    Notes: Abstract PURPOSE: This goal of this research was to develop and evaluate the psychometrics of a health-related quality of life scale developed to address issues related specifically to fecal incontinence, the Fecal Incontinence Quality of Life Scale. METHODS: The Fecal Incontinence Quality of Life Scale is composed of a total of 29 items; these items form four scales: Lifestyle (10 items), Coping/Behavior (9 items), Depression/Self-Perception (7 items), and Embarrassment (3 items). RESULTS: Psychometric evaluation of these scales demonstrates that they are both reliable and valid. Each of the scales demonstrate stability over time (test/retest reliability) and have acceptable internal reliability (Cronbach alpha 〉0.70). Validity was assessed using discriminate and convergent techniques. Each of the four scales of the Fecal Incontinence Quality of Life Scale was capable of discriminating between patients with fecal incontinence and patients with other gastrointestinal problems. To evaluate convergent validity, the correlation of the scales in the Fecal Incontinence Quality of Life Scale with selected subscales in the SF-36 was analyzed. The scales in the Fecal Incontinence Quality of Life Scale demonstrated significant correlations with the subscales in the SF-36. CONCLUSIONS: The psychometric evaluation of the Fecal Incontinence Quality of Life Scale showed that this fecal incontinence-specific quality of life measure produces both reliable and valid measurement.

    Notes: Abstract PURPOSE: This study was performed to determine the quality of life and cost-effectiveness of therapeutic options for patients with locally recurrent rectal carcinoma, determined from the perspectives of patients and health care providers. METHODS: We reviewed the records of patients (N=68) with locally recurrent rectal carcinoma evaluated from 1992 through 1995. We constructed a decision-analytic model incorporating outcomes, survival, and costs. Utilities were elicited from convenience samples of health care providers and patients using the standard gamble technique. RESULTS: The median survival for patients undergoing surgical resection (n=40) was 42 months, compared with 16.8 months for patients undergoing diagnostic or palliative surgery (n=16) and 18.3 months for patients treated nonoperatively (n=12;P〈0.005). The mean cost of treatment per patient was $19,283 for the nonoperative group, $45,647 for the diagnostic or palliative surgery group, and $70,878 for the surgical resection group. The diagnostic or palliative surgical strategy was dominated by the nonoperative strategy because the former had greater costs with fewer health benefits. The incremental cost-utility ratio of surgical resection compared with nonoperative management using health care provider utilities was $109,777 per quality-adjusted life year gained; it was reduced to $56,698 using per quality-adjusted life year using mean patient utilities. CONCLUSIONS: Patients with recurrent rectal carcinoma view surgery and morbidity to be less severe than health care providers. Diagnostic or palliative surgery is expensive and affects quality-adjusted survival adversely compared with nonoperative therapy. Surgical resection may be a cost-effective use of resources, particularly when cost-effectiveness is calculated using patient preferences.

    Notes: Abstract PURPOSE: The aim of this study was to determine rates of complications and extent of benefits for laparoscopic-assisted colectomy compared with open colectomy in patients older than age 75. METHODS: Forty-two patients undergoing laparoscopic-assisted colectomy (1992–1998) were matched to 42 open colectomy patients for gender, age, year of surgery, operating surgeon, and procedure. Health status (American Society of Anesthesiology score), previous abdominal surgery, conversion rate, surgical outcome, and need for assistance at admission and dismissal (independencevs. home with assistancevs. nursing facilities) were reviewed. RESULTS: Mean ages were 81.2 and 80.5 years for laparoscopic-assisted colectomy and open colectomy, respectively (P=not significant). Twenty-one laparoscopic-assisted colectomy and 23 open colectomy patients were females. American Society of Anesthesiology scores were comparable, as were rates of previous abdominal surgery (57 percent for laparoscopic-assisted colectomyvs. 62 percent for open colectomy;P=not significant). Mean operative times were longer for laparoscopic-assisted colectomy (190 minutes for laparoscopic-assisted colectomyvs. 142 minutes for open colectomy;P〈0.001); operating room times progressively decreased from 221 minutes in 1992 to 1995 to 147 in 1998 for laparoscopic right hemicolectomy (P〈0.001). The conversion rate for laparoscopic-assisted colectomy was 14.3 percent. There were no deaths in either group, and laparoscopic-assisted colectomy was associated with fewer morbidities (14.3 percent for laparoscopic-assisted colectomyvs. 33.3 percent for open colectomy;P=0.04), narcotic usage (2.7vs. 4.8 days;P〈0.001), time to return to bowel movements (3.9vs. 5.9 days;P〈0.001), and length of hospital stay (6.5vs. 10.2 days;P〈0.001). Independent status at admission in 37 laparoscopic-assisted colectomy and 38 open colectomy patients was maintained at discharge by 35 laparoscopic-assisted colectomyvs. 29 open colectomy patients (P=0.025). CONCLUSIONS: Laparoscopic-assisted colectomy is safe and beneficial, including preservation of postoperative independence, to the elderly when compared with open colectomy.

    Notes: Abstract Background: There have been significant developments and advances in the area of outcomes research in the past 25 years. Unfortunately, many surgical oncologists may not have a clear concept of outcomes research and the methodology involved. Methods: A literature-based review article was done that included an overview of outcomes research, and study design and types, outcome measures, outcome instruments, and sources of outcome data were examined. In addition, we reviewed small area variation(volume outcome analysis as well as quality-of-life studies and their applications in surgical oncology clinical investigation. Specific examples from surgical oncology were identified. Results: As the costs of health care have increased, so has the emphasis on measuring outcomes of medical and surgical care to determine the quality and appropriateness of care. Marked variations in a variety of outcomes after oncological procedures have been attributed to individual surgeon and institution characteristics. Because much of the clinical surgical oncology literature deals only with the traditional mortality and morbidity outcomes, a more comprehensive examination of patient outcomes is required to fully evaluate the impact of patient management decisions. Health-related quality of life can be measured and analyzed in several ways and decisions regarding the use of such methodology are dependent on multiple factors. Conclusions: Surgical oncologists should recognize that the true value of their interventions requires systematic and comprehensive examination of patient outcomes.

    Notes: Abstract Background: The aim of the present study was to examine whether type of surgery, age, and time since surgery influenced psychological distress and quality of life (QOL) in women treated for breast cancer. Methods: We surveyed 183 women who had undergone surgery for breast cancer. Psychological distress was measured with the Mental Health Inventory and QOL was measured with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. Results: After controlling for stage of disease, radiation treatment, and age, there was a statistically significant interaction between type of surgery and time since surgery for the Mental Health Inventory total score, and a marginal interaction between type of surgery and time since surgery for the Global health status/QOL score. Women who had breast conservation surgery experienced significantly greater levels of psychological distress and marginally worse QOL from 40 months after surgery onward than did women who received a mastectomy. Conclusions: The effects of different surgical treatments for breast cancer on psychological distress and QOL become apparent only after a period of several years. Women, therefore, need counseling on the potentially positive and negative psychological implications of different surgical treatments for breast cancer.

    Notes: Abstract PURPOSE: Despite high patient satisfaction with a pelvic pouch, patients experience some bowel dysfunction. Patients whose indication for surgery is neoplasia may have near-normal preoperative bowel function. We hypothesized that these patients would be less accepting of a poorer functional status after surgery, reflected in a poorer measure of quality of life. METHOD: Sixteen patients who had dysplasia or cancer as the primary indication for surgery were compared with a matched control group whose indication for surgery was failed medical therapy. Quality of life was assessed using one disease-specific instrument, the Inflammatory Bowel Disease Questionnaire, two generic quality-of-life instruments, the Sickness Impact Profile and the Short Form 36, and two utility assessments. RESULTS: The groups were well matched with no significant differences in functional outcome. Quality-of-life scores were high in both groups and there were no significant differences in overall quality of life between the two groups using all five instruments. There was evidence of a response shift phenomenon in the failed medical therapy control group. CONCLUSION: Quality of life of patients who have a pelvic pouch for colitis-associated neoplasia is excellent and the same as that of patients who have a pouch for failure of medical therapy.

    Notes: Abstract PURPOSE: Locally advanced primary and recurrent rectal cancers treated with external beam radiation therapy, intraoperative radiation therapy, and chemotherapy represent a complex group of patients in the setting of extensive pelvic surgery and sphincter preservation. We sought to define functional outcome and quality of life in this subset of patients. METHODS: We retrospectively reviewed our experience with locally advanced primary and recurrent rectal cancer patients who underwent intraoperative radiation therapy with either low anterior resection (n=12) or coloanal anastomosis (n=6) between 1991 and 1998. Current functional outcome and quality of life were evaluated by a detailed questionnaire. RESULTS: Median time from operation to assessment was 24 (range, 6–93) months. Using a standardized Sphincter Function Scale, incorporating the number of bowel movements per day and degree of incontinence, patients were graded as poor, fair, good, or excellent function. Of all patients, 56 percent reported unfavorable (poor or fair) function. Of the subset of patients with coloanal anastomosis or very low low anterior resection, 88 percent had unfavorable function as compared with 30 percent with standard low anterior resection. (P=0.02; Fisher's exact probability test). A quality-of-life satisfaction score based on social, professional, and recreational restrictions demonstrated 56 percent of patients to be dissatisfied with their bowel function. CONCLUSIONS: The majority of patients with advanced rectal cancers who require external beam radiation therapy, extensive pelvic surgery, and intraoperative radiation therapy report unfavorable functional and quality-of-life outcomes after sphincter preservation. In this setting patients being considered for coloanal anastomosis or very low anterior resection may be better served by permanent diversion.

    Notes: Abstract PURPOSE: The surgical treatment of fistula-in-ano frequently results in recurrence of the fistula or postoperative anal incontinence. Despite these problems, most patients are satisfied with the results of their surgery. To clarify this apparent discrepancy, we attempted to identify factors that affect patient's lifestyles and may contribute to their satisfaction. METHODS: A questionnaire was mailed to 624 patients surgically treated for cryptoglandular fistula-in-ano at the University of Minnesota during a five-year period. Three hundred seventy-five patients returned their questionnaires. Patients who were followed up for a minimum of one year were included in this retrospective study. Associations between postoperative complications and patient satisfaction were identified by chi-squared tests and multiple logistic regression. Attributable fractions for patient dissatisfaction were calculated using study population dissatisfaction rates. RESULTS: Patient satisfaction was strongly associated with fistula recurrence, difficulty holding gas, soiling of undergarment, and accidental bowel movements. Effects of incontinence on patient quality of life were also significantly associated with patient satisfaction as was the number of lifestyle activities affected by incontinence. Patients with fistula recurrence reported a higher dissatisfaction rate (61 percent) than did patients with anal incontinence (24 percent), but the attributable fraction of dissatisfaction for incontinence (84 percent) was greater than that for fistula recurrence (33 percent). Patient satisfaction was not significantly associated with age, gender, history of previous fistula surgery, type of fistula, surgical procedure, time since surgery, or operating surgeon. CONCLUSION: Patient satisfaction after surgical treatment for fistula-in-ano is associated with recurrence of the fistula, the development of anal incontinence, and with the effects of anal incontinence on patient lifestyle. In our series of patients treated mainly with laying open of the fistula tract, patients with fistula recurrence had a higher dissatisfaction rate than did patients with anal incontinence. However, because anal incontinence was more prevalent than fistula recurrence, a higher fraction of dissatisfaction was attributable to anal incontinence.

    Notes: Abstract Background: In this study, we used a previously well-validated survey to assess the impact of different forms of urinary diversion on overall quality of life in patients with bladder cancer. Methods: A total of 92 patients, having three different forms of urinary diversion after radical cystectomy, completed by mail the SF-36, a validated quality-of-life survey. All patients had local(regional disease at the time of cystectomy and are currently without evidence of disease. Completed surveys were then analyzed into physical (PCS) and mental (MCS) component quality-of-life scores per published protocols. Results were then compared with published age-based norms. Results: A total of 38 men who had cystectomy and ileal neobladder had a mean PCS (6SD) of 48.4 (7.8) and a mean MCS of 51.0 (7.4); 16 men and women who had cystectomy and Indiana Pouch had a mean PCS of 48.4 (8.9) and a mean MCS of 55.7 (3.8). None of these results is statistically different from published age- and sex-based population norms. Thirty-eight men who had cystectomy and ileal conduit had a mean PCS of 41.4 (8.5) and a mean MCS of 48.2 (10.7). The PCS is not statistically different from the population-based norm; however, the MCS is significantly decreased from the published norm (P 5.01). Conclusions: Patients with ileal conduits have significantly decreased mental health quality of life whereas patients with continent urinary diversions do not. Therefore, when not medically contraindicated, patients should be offered a continent diversion as the diversion of choice after cystectomy.

    Notes: Abstract PURPOSE: The hypothesis is that the impact of a temporary stoma on a patient's daily life is determined by complications and related stoma care problems. METHOD: A prospective clinical trial was performed, studying complications and social well-being of 37 patients with loop ileostomy and 39 patients with a loop colostomy (randomly assigned comparison). Patients were categorized according to degree of social restriction. The association between the degree of social restriction and the presence of stoma care problems and complications was assessed. Follow-up was scheduled every three months until the stoma was closed (94 percent). RESULTS: There is no relation between stoma type (ileostomy or colostomy) and degree of social restriction (chi-squared test,P=0.42). The more stoma care problems or complications seen, the higher the degree of social restriction: significantly more stoma care problems were seen in the completely isolated group of patients when compared with the patients who were less socially restricted (Spearman correlation coefficient 1=0.35,P=0.003). Especially stoma leakage, peristomal skin irritation, dietary prescriptions, retraction, and prolapse of the stoma have significant impact on the patient's daily life. CONCLUSION: Stoma surgery has a great influence on a patient's daily life. There is a clear relation between the number of stoma care problems and the degree of social restriction. Follow-up of stoma patients under close surveillance of stoma care nurse to minimize stoma care problems and a careful surgical technique are advocated for good stoma care.

    Notes: Abstract The thoracic cage after a lung resection is filled by the remaining lobes, the elevated diaphragm, the diminished thoracic cage, and by mediastinal shifting. The changes in the thorax after a lung resection were quantified using magnetic resonance imaging. The study group consisted of 39 patients who had undergone a lobectomy, four who had undergone a pneumonectomy, and 14 controls. The left ventricular angle, ascending aortic angle, mediastinal shift, longitudinal length of the thoracic cage, the distance between the thoracic apex and the level of the aortic valve, and diaphragmatic elevation were all measured. After a right lower lobectomy, the mediastinum shifted more rightward than after a right upper lobectomy. The diaphragm became more greatly elevated after a right upper lobectomy than after a right lower lobectomy. When a chest wall resection was added to a right upper lobectomy, the mediastinal anatomical changes decreased. After a left upper lobectomy, the degree of mediastinal shifting was greater than after a left lower lobectomy. A left upper lobectomy shifted the mediastinum at the level of the right atrium. This method is easily reproducible and was found to be effective for quantifying the changes in the thorax after a lung resection.

    Notes: Abstract: Little is known about the effectiveness of transcatheter chemotherapy in liver metastases from gastric cancer. The aim of this study was to evaluate the initial results of hepatic artery infusion and oily chemoembolization in these liver secondaries. Courses of transcatheter arterial infusion with 5-fluorouracil/doxorubicin (12 patients) and oily chemoembolization with doxorubicin-in-iodized oil and gelatin sponge (12 patients) were performed in 24 patients with histologically proven unresectable gastric cancer liver metastases. A positive effect of treatment (partial response + stabilization) was seen in 92% of the patients after chemoinfusion and in 50% after chemoembolization. The 1- and 2-year actuarial survival rates were 92% and 53% for infusion vs 50% and 17% for chemoembolization, respectively (log-rank test, P = 0.0009). For patients who had already died, the mean survival was 19.2 months vs 9.5 months (Student's t-test, P 〈 0.05) with median survivals of 23 months vs 8 months, respectively. The results with arterial infusion were very close to those reported for liver resection. Transcatheter therapy appears to be useful for the palliation of unresectable liver metastases from gastric cancer. If regional chemotherapy is used, arterial infusion should be the first-choice treatment, with oily chemoembolization being reserved for patients who do not respond to infusion.

    Notes: Abstract Purpose:A multi-centric trial was performed to explore theclinical activity, in terms of response and toxicity (primary objectives),duration of response and survival (secondary objectives), of docetaxel withcisplatin in advanced gastric cancer (AGC). Patients and methods:Patients with measurable unresectable and/ormetastatic gastric carcinoma, performance status ≤1, normal hematological,hepatic and renal functions and not pretreated for advanced disease bychemotherapy received up to eight cycles of TC (docetaxel 85 mg/m2d1, cisplatin 75 mg/m2 d1) q3w. Dose escalation to 100mg/m2 was performed in five patients and was discontinued forexcessive toxicity. Results:Forty-eight patients were accrued. A median of 5cycles/patient was given. We observed 2 complete and 25 partial responses foran overall intent to treat response rate of 56% (95% CI:41%–71%). Twelve patients had stable disease for ≥9weeks (3 cycles). The median time to progression and overall survival were 6.6and 9 months, respectively. Grade ≥3 toxicities were neutropenia81%, anemia 32%, thrombocytopenia 4%, alopecia36%, fatigue 9%, mucositis 9%, diarrhea 6%,nausea/vomiting 4%, neurologic 2%, and one anaphylaxisprecluding treatment administration. We recorded nine episodes of non-fatalfebrile neutropenia in eight patients, two of them with docetaxel at 100mg/m2. There were no direct treatment-related deaths. Conclusions:TC is active in AGC with a high response rate in amulticentric trial. Despite its hematotoxicity, this regimen is well toleratedand can be recycled as originally planned in 78% of the cases. Theseresults may serve as basis for further developments of docetaxel containingregimens in this disease.

    Notes: Abstract Background:Concomitant chemoradiotherapy is an effectivetreatment modality for advanced head and neck cancer, but improved regimensare needed. We sought to define the toxicities, recommended phase II dose, andoutcome of a combination chemotherapy regimen with concomitanthyperfractionated radiotherapy in patients with poor prognosis cancers of thehead and neck, including those having received prior curative intentradiotherapy. Patients and methods:From 1995 until 1997, 54 patients weretreated, 25 of whom had received a prior full course of radiotherapy to thehead and neck. Patients were treated with 5-fluorouracil (5-FU) 600mg/m2/day continuous infusion × 5 days (days 1–5),hydroxyurea, 500 mg p.o. bid × 11 doses (days 1–6) and paclitaxel(60–150 mg/m2) by one-hour infusion on day 2 using a doseescalation strategy. Radiotherapy was given concomitantly on days 2–6,150 cGy bid. Each of 4–5 cycles was delivered every other week. Results:The MTD of paclitaxel was 100 mg/m2. Theregimen was feasible; radiotherapy was delivered at a median of 7300 cGy and83% of patients received ≥80% planned dose intensity.Hematological toxicity, with granulocyte colony stimulating factor, was verymild. Dose limiting toxicities were mucositis and dermatitis. Despite poorprognosis, two-year survival was 45%. Conclusions:The recommended phase II dose of this regimen is 5-FU600 mg/m2/day × 120 hours (days 1–5), hydroxyurea 500mg p.o. b.i.d. × 11 doses (days 1–6), paclitaxel 100mg/m2 over one hour on day 2, and radiotherapy 150 cGy b.i.d. days2–6. Concomitant chemotherapy and re-irradiation was feasible on thisprotocol and resulted in long-term survival in patients without other curativeintent options.

    Notes: Abstract Background:Pneumothorax occurring in the absence of obvious lungdisease is defined as spontaneous pneumothorax. Spontaneous pneumothoraxoccurs in a variety of settings in patients with malignancies. Patients and methods:We present a case report of spontaneouspneumothorax in malignancy and review the literature. Results:No correlation was found between the occurrence ofpneumothorax with age, sex or smoking history. Pneumothorax occurred with avariety of primary tumors. However it was always associated with lungmetastases or lung involvement with tumor. In certain cases the metastaseswere detected after the occurrence of pneumothorax. Conclusions:The occurrence of pneumothorax in a patient withmalignancy should prompt a search for lung metastases.

    Notes: Abstract Background:The combination of paclitaxel (P) and carboplatin (C)is an effective treatment for advanced NSCLC. Gemcitabine (G) is an active newdrug. We planned a phase I study to find the maximum tolerated dose (MTD) ofthe PCG combination. A phase II study was subsequently conducted to evaluatethe activity and toxicity of PCG. Patients and methods:Forty-five patients entered the study.Twenty-eight had stage IIIA–B disease, 17 stage IV. In the phase Istudy, with a fixed dose of C at AUC = 6 on day 1, P was escalated usingincrements of 25 mg/m2 starting from 175 mg/m2 on day1 and G with increments of 200 mg/m2 starting from 800mg/m2 on day 1 and 8. Results:Fourteen patients entered the phase I study. The MTD wasreached at P 200 mg/m2, C AUC = 6 and G 1000 mg/m2.Neutropenic fever and grade 3 diarrhea were the dose limiting toxicities.Thirty-one patients were treated in the phase II study with P 175mg/m2, C AUC = 6 and G 1000 mg/m2. Response rate was57% (68% in stage III and 47% in stage IV).Myelosuppression was the main toxicity, with grade 3–4 leukopeniaoccurring in 35% of cases. Grade 3 anemia was observed in 24%of cases and grade 3–4 thrombocytopenia occurred in 34% ofpatients. Non-hematological toxicity was mild. Median survival and one-yearactuarial survival were 20.5 months and 74% for stage III and 11.5months and 47% for stage IV. Conclusions:PCG is a promising regimen for treating advancedNSCLC. A phase III study comparing PCG to paclitaxel plus carboplatin inadvanced NSCLC is ongoing. On the other hand, we are planning to introduce thePCG regimen in the treatment of stage II–III patients in the setting ofa multimodality treatment.

    Description / Table of Contents: Summary A vital X-ray imaging technique in oral and craniomaxillofacial surgery is the panoramic X-ray. Due to its variety of special projections, including imaging of the transversal level and low exposure to radiation, it is suitable for answering many clinical questions and for diagnostics of various findings. It has become possible to minimize the necessary doses by further development of technology and devices, as well as of X-ray films and by new detection systems, such as sensors or screens. In some clinical cases, the diagnostic deficiencies of conventional imaging techniques make computed tomography (CT) and magnetic resonance (MR) imaging indispensable. Although MR is particularly suitable for soft tissue imaging, it has also become helpful in finding cortical changes by shorter measuring times. In certain cases, e. g., changes to bone metabolism, differentiated methods of nuclear medicine make image-aided analysis of function possible.
    Notes: Zusammenfassung Zentrale Aufnahmeart in der Röntgendiagnostik der Mund-, Kiefer- und Gesichtschirurgie ist die Panoramaschichtaufnahme. Mit ihren zahlreichen Spezialprojektionen einschließlich der Abbildung der Transversalebene ist sie für die Abklärung zahlreicher Fragestellungen mit geringer Strahlenexposition geeignet. Die Verringerung des Dosisbedarfs ist weiterhin durch Fortentwicklungen der Gerätetechnik, der Röntgenfilme und durch neue Detektionssysteme wie z. B. Sensoren oder Speicherfolien möglich geworden. Diagnostische Unzulänglichkeiten der konventionellen Aufnahmearten machen bei zahlreichen klinischen Fragestellungen der Mund-, Kiefer- und Gesichtschirurgie eine Bildgebung mittels Computertomographie und Kernspintomographie unumgänglich. Obgleich die Kernspintomographie v. a. für die Weichteildiagnostik vorrangig geeignet ist, erlaubt sie mittlerweile, aufgrund der Verkürzung der Messzeiten, auch Veränderungen der Kortikalis abzubilden. Bei bestimmten Fragestellungen, wie z. B. Veränderungen des Knochenmetabolismus, ermöglichen differenzierte nuklearmedizinische Verfahren eine abbildungsunterstützte Funktionsanalyse.

    Notes: Abstract The spinal dorsal horn is known for its important functional role in the field of transmission and modulation of sensory afferents. Because of this, the dorsal horn represents a target for numerous analgesic and antispastic procedures. Thus, it would be interesting to develop imaging dedicated to this spinal structure. The purpose of this study was to investigate the radiologic anatomy of the cervical dorsal horn by magnetic resonance imaging (MRI) (1.5T). The first step consisted in the validation of the anatomic information provided by MRI on 5 human cadavers. A spin-echo sequence (T2, 2000/45) enabled the demonstration of good correlations between histologic sections and axial MRI slices performed at the corresponding cervical levels. The second step was the 〈〈in vivo〈〈 exploration of 20 subjects, aiming at the development of a gradient echo sequence (T2*) with a conventional MRI unit, compatible with a routine clinical examination. The dorsal horn was clearly identified in 77% of the axial slices performed (n = 300). The angle between the dorsal horn axis and the sagittal plane was measured as from 25.5˚ at C2 to 40˚ at C8 segments. The results of this anatomico-radiologic study of the cervical dorsal horn suggest that preoperative MRI could be useful to design the surgical approach to this structure, as performed during cervical microsurgical drezotomy (DREZ = dorsal root entry zone) for the treatment of selected cases of chronic pain or disabling spasticity in the upper limbs.

    Notes: Abstract Colonoscopy is an invasive technique, frequently incomplete and often poorly tolerated in elderly patients. New, less invasive modalities are being developed to diagnose moderate-sized adenomatous polyps and colorectal caners which involve pneumo- or hydrocolography with high-resolution surface imaging, either by CT or MR scanning. This approach has recently been supplemented by complex image post-processing to provide a form of virtual colonoscopy which takes account of projected colonic direction and which can map for mucosal anomalies. It remains to be seen how sensitive these newer techniques are and whether defined algorithms for colonic representation can be agreed upon which will prove both accurate and cost-effective both in symptomatic and screening populations.

    Notes: Abstract Using BOLD-fMRI we have previously documented activation of the red nucleus (RN) and substantia nigra (SN) during spontaneously and visually activated migraine headache. These observations prompted us to study brainstem function in chronic daily headache patients using high-resolution magnetic resonance imaging (MRI) techniques. Seventeen chronic daily headache (CDH) patients, ten episodic migraine (EM) patients and fifteen controls (N) were imaged with a 3 tesla MRI system. For each subject, the relaxation rates R2, R2* and R2' were obtained for RN and SN. There was a significant decrease in R2' and R2* values for RN and SN in CDH compared to N and EM groups (p 〈 0.05), but no significant difference between the N and EM groups. A decrease in R2' and R2* indicates reduced deoxyhemoglobin and hence persistent activation of the RN and SN in CDH patients most likely secondary to ongoing headache at the time of study. The imaging data provide objective evidence of disturbed central nervous system function in CDH.

    Notes: Abstract Purpose:We conducted a phase II multicentre study of gemcitabinein patients with anaplastic astrocytoma and glioblastoma multiforme at firstrelapse. Patients and methods:Patients with anaplastic astrocytoma orglioblastoma multiforme receiving a stable dose of steroids and ECOGperformance status ≤3 were eligible for this study at the time of firstrelapse. One adjuvant chemotherapy regimen was permissible. Patients receivedgemcitabine 1000 mg/m2 i.v. weekly × 3, repeated on afour-weekly cycle. Results:Of 20 patients enrolled, 15 were evaluable for response,19 for non-hematological toxicity and 18 for hematological toxicity. Sevenpatients had anaplastic astrocytoma (AA) and twelve glioblastoma multiforme(GBM). Age ranged from 28–71 years (median 50). Fifteen patientsdiscontinued therapy due to disease progression. The median number of cyclesadministered was 1 (range 1–11); only two patients received more thanthree cycles. Hematologic toxicity was acceptable and no grade 4 toxicity wasseen. One patient developed Pneumocystispneumonia and eventualpulmonary embolism; one died of gastric hemorrhage related to steroid therapy.No objective responses were seen. Nine patients had stable disease (medianduration 2.7 months, range 0.9–11.2). Conclusions:Gemcitabine given in this dose and schedule seemswell tolerated but is not active in patients with recurrent high-gradegliomas.

    Notes: Abstract Background:The cytotoxic agent bendamustine combines apurine-like benzimidazol and alkylating nitrogen mustard group. The clinicallytolerated dose for single bolus bendamustine is 215 mg/m2, forfractionated therapy on four consecutive days 85 mg/m2. The maximumtolerated dose of a day 1 and 8 (q4w) 30 min infusion schedule was recentlyfound to be 160 mg/m2, mouth dryness and fatigue weredose-limiting. Our current phase I trial was designed to define therecommended dose of a new weekly short infusion schedule. Patients and methods:Patients with refractory malignant tumoursqualified for the trial after written informed consent was obtained.Bendamustine was given as a 30-min i.v. infusion weekly for up to eightconsecutive weeks. Results:Twelve patients (8 male, 4 female, median age 57.5 years,range 42–64) were enrolled in this trial. At the starting dose of 80mg/m2, two patients had dose-limiting toxicity (fatigue grade 3,mouth dryness grade 3, fever grade 4 Common Toxicity Criteria). Nodose-limiting events were observed in six patients treated at 60mg/m2. An intermediate dose level of 70 mg/m2 wasstudied in three younger, less heavily pre-treated patients, was welltolerated and not associated with dose-limiting events. Haematologicaltoxicity was mild except for grade 3–4 lymphocytopenia, occurring in 11of 12 patients. Bendamustine was found to induce long-lastingpanlymphocytopenia with predominant B-cell cytotoxicity. Conclusions:The maximum tolerated dose of weekly bendamustinegiven as a 30-min i.v. infusion is 80 mg/m2, mouth dryness, fatigueand fever are dose-limiting. The recommended dose for phase II trials is 60mg/m2.

    Notes: Abstract Background:Standard therapy for lymphoma consists of acyclophosphamide (C), doxorubicin, vincristine (V), and prednisone (P) (CHOP)combination regimen. Liposomal daunorubicin (DaunoXome®) is an alternativeto doxorubicin for patients with lymphoma because of its more favorable safetyprofile and potentially more selective uptake in lymphoma. The objectives ofthis study were to determine the maximum tolerated dose (MTD) of liposomaldaunorubucin with CVP (COP-X) and the tolerability of the regimen in patientswith indolent lymphoma. Patients and methods:Patients with low-grade andintermediate-grade lymphoma having adequate cardiac, hepatic, and renalfunction were enrolled. Patients received C 750 mg/m2, V 1.4mg/m2 (maximum 2.0 mg), and liposomal daunorubicin 50–100mg/m2 i.v. on day 1 and P 100 mg p.o. on days 1–5. MTD wasthe liposomal daunorubicin dose associated with 20% dose-limitingtoxicity (ANC 〈500/mm3 for 〉5 days or febrile neutropenia). Results:Twenty patients, median age 59 years, were treated. Theliposomal daunorubicin MTD combined with CVP was 70–80 mg/m2,depending on patient population. No significant non-hematologic toxicityoccurred. Response rate was 44% (2 complete and 5 partial responses). Conclusions:A liposomal daunorubicin dose of 80 mg/m2in the COP-X regimen was well tolerated with little non-hematologic toxicity.

    Notes: Abstract Background:Several studies have investigated the possible roleof the adjuvant chemotherapy after curative resection for gastric cancerfailing to show a clear indication; previous meta-analyses suggested smallsurvival benefit of adjuvant chemotherapy, but the statistical methods usedwere open to criticisms. Materials and methods:Randomised trials were identified by meansof Medline and CancerLit and by selecting references from relevant articles.Systematic review of all randomised clinical trials of adjuvant chemotherapyfor gastric cancer compared with surgery alone, published before January 2000,were considered. Pooling of data was performed using the fixed effect model.Death for any cause was the study endpoint. The hazard ratio and its95% confidence intervals (95% CI), derived according to themethod of Parmar, were the statistics chosen for summarising the relativebenefit of chemotherapyversuscontrol. Results:Overall 20 articles (21 comparisons) were considered foranalysis. Three studies used single agent chemotherapy, seven combination of5-fluorouracil (5-FU) with anthracyclin, ten combination of 5-FU withoutanthracyclines. Information on 3658 patients, 2180 deaths, was collected. Chemotherapy reduced the risk of death by 18% (hazard ratio 0.82,95% CI: 0.75–0.89, P 〈 0.001). Association ofAnthracyclines to 5-FU did not show a statistically significant improvementwhen compared with the effect of the other regimens. Conclusions:Chemotherapy produces a small survival benefit inpatients with curatively resected gastric cancer. However, taking into accountthe limitations of literature based meta-analyses, adjuvant chemotherapy isstill to be considered as an investigational approach.

    Description / Table of Contents: Zusammenfassung. Filme erzählen Geschichten. Spannungsvoll sind dabei vor allem jene Szenen, in denen Menschen vor Entscheidungskonflikte gestellt werden. Medizinethische Konflikte tauchen dabei nicht nur in Arztserien oder Krankheitsdarstellungen auf, sondern häufig in Genres, in denen diese Thematik kaum vermutet wird: Komödien, Western, Liebesfilmen, Gangster- und Kriminalfilmen. Indem Filme derartige Konflikte inszenieren und Lösungen bieten, greifen sie auf moralische Werthaltungen zurück und sind zugleich Seismographen für die gesellschaftliche Relevanz medizinethischer Themenfelder. Allerdings können im Film ethische Prinzipien der Entscheidungsfindung der Dramaturgie der Handlung zum Opfer fallen. Eine Analyse der dargestellten Konfliktsituationen ähnelt einer medizinethischen Fallbesprechung und stellt eine hilfreiche Ergänzung für die Vermittlung analytischer und kommunikativer Kompetenzen dar.
    Notes: Abstract. Movies tell stories. Thrilling are especially those situations, when people have to make ethical decisions. Issues of medical ethics crop up not only in hospital series, but often in genres where this subject is hardly to be supposed: comedies, westerns, love stories and gangster movies. Enacting these conflicts means offering a solution, and in doing so films refer to moral values and – at the same time – function as seismographs for the social relevance of bioethical topics. But it is possible that ethical principles of good decision-making fall victims to the drama of the story. Analysis of the portrayed conflict is similar to a case discussion in bioethics and represents a helpful adjunct to the procurement of analytical and communicative competences.

    Notes: Abstract  Four subependymomas of the lateral ventricle were reviewed with regard to clinical presentation, neuroimaging features, treatment, histopathological features, and long-term follow-up. There were two male and two female patients ranging in age from 27 to 60 years (mean 48.3 years). While two patients presented with symptoms and signs of raised intracranial pressure, two others were found incidentally during neuroimaging investigations to have intraventricular tumors. Neuroimaging characteristics of these tumors included no paraventricular extension, iso- or hypodensity with minimal enhancement on computerized tomography (CT), or iso- or hypointensity on T1-weighted and hyperintensity on T2-weighted magnetic resonance images (MRI). The usual finding on MRI was of no or scarce contrast enhancement, but one case showed heterogeneous enhancement. Three patients underwent total resection of the tumor and one underwent partial resection. No patients received postoperative radiation therapy. All patients have been doing well 4.8 to 15.4 years (mean 8.8 years), after surgery. Although there are no absolutely specific features to distinguish these tumors from other intraventricular tumors preoperatively, subependymoma should be kept in mind for differential diagnosis, as this tumor may safely be removed without sacrificing contiguous normal tissue and with good long-term results.

    Notes: Abstract Background: Chemotherapy using multi-drug regimens is consideredmore active than single-agent therapy. This may be due to synergisticinteractions or, simply, a higher probability of administering an activeagent. We investigated in vitrothe type of drug interactions in arecognized regimen in relationship to tumour type and drug sensitivity. Patients and methods: The possibility of synergistic and additiveinteractions between individual cytotoxic drugs was investigated for thecomponent drugs of the established FEC regimen, i.e., 5-fluorouracil,epirubicin and cyclophosphamide, in 243 patient tumour samples representingvarious drug sensitivity using the non-clonogenic fluorometric microculturecytotoxicity assay. Results: Using a cell survival of ≤50% as a limit fordrug activity and sample sensitivity, the overall response rates to the mostactive single drug (Dmax) and the combination were 56% and64%, respectively, with a distribution among diagnoses similar to thatin the clinic. For 86% of the samples there was concordance withrespect to judgement of activity using either Dmax or thecombination. For samples being sensitive to at least one single drug,95% were also sensitive to the combination whereas for samples withinsignificant Dmax effect, only 2% were sensitive to thecombination. In samples with modest Dmax effects, i.e., cellsurvival in the range 〉50%–≤80%, 45%responded to the combination. The effect of the combination was generally wellpredicted from the Dmax effect. Conclusions:The superior antitumour effect of drug combinationscompared with single drugs may be due to the higher chance of selecting anactive agent. However, for intermediately sensitive tumours, additionalinteraction effects of a combination may be of clinical significance.

    Notes: Abstract Background:Gemcitabine is active in patients with otherwiseresistant or refractory ovarian cancer. As the drug is well tolerated, studiesusing gemcitabine combined with other antineoplastic agents are needed. Theaim of the study was to determine the maximum tolerated dose (MTD) ofepirubicin combined with gemcitabine, with and without support of G-CSF. Patients and methods:Patients with platinum-resistant orrefractory ovarian cancer were eligible. Gemcitabine (G) (starting dose 800mg/m2 day 1 and 8; 200 mg/m2 escalation per level) andepirubicin (E) (starting dose 60 mg/m2 day 1; 15 mg/m2escalation per level) were given every 21 days for four to six cycles. G-CSF(filgrastim 5 µg/kg/die) was given in case of grade 4 neutropenia(levels without support) or from day 9 up to leukocyte count〉10,000/mm3 after nadir (levels with support). Cohorts of threepatients were enrolled at each level, and another three patients were planned,if one dose-limiting toxicity (DLT) was registered. MTD was determined firstwithout and then with G-CSF. Results:Four levels were studied (G 800 + E 60; G 1000 + E 60;G 1000 + E 75; G 1000 + E 75 + G-CSF) with four, four, three and threepatients enrolled, respectively. DLT (grade 4 febrile neutropenia) wasobserved in two patients at level 3. Thus, G1000 + E 60 mg/m2 wasthe MTD without G-CSF. The addition of prophylactic G-CSF did not allow afurther increase of the dose and grade 4 thrombocytopenia was the DLT at level4. Non-hematological toxicity was mild. Grade 2 mucositis was reported in fourpatients. Among the 13 patients with measurable or evaluable disease, 3partial responses were observed for an overall response rate of 23.1%. Conclusions:The combination of gemcitabine 1000 mg/m2(day 1, 8) and epirubicin at 60 mg/m2 (day 1) is a feasibletherapy. Grade 4 neutropenia is frequent and G-CSF support is often required.With prophylactic support of G-CSF, the DLT is thrombocytopenia.

    Notes: Abstract Background:Primary cerebral non-Hodgkin's lymphomas (NHL) inimmunocompetent patients (PCL) are located exclusively in the central nervoussystem, the eye, or meninges. Clinical management of these patients remainscontroversial. Patients and methods:Clinical characteristics of the patients andparameters influencing their outcome as of December 1998 were investigated andregistered in a database of 226 patients treated in the French Federation ofCancer Centers between 1980 and 1995. Results:Most PCL are diffuse large-cell NHL with a B phenotype.The incidence of PCL has been steadily increasing over the past 20 years insome but not all countries. The overall survival of primary cerebral lymphoma(PCL) patients in the published series, a median of 12–16 months and afive-year survival of 5%–20%, is poor. Several series havenow reported long-term survivals of more than 10 years and PCL may thereforebe a curable tumor in some patients. The optimal treatment of PCL is notknown. Complete resection of the tumor does not improve outcome andmultidisciplinary approaches combining chemotherapy and radiotherapy are nowcommonly used, although the superiority of combination over radiotherapy- orchemotherapy-alone has never been demonstrated in a phase III trial. Theoptimal chemotherapy regimen, the dose and even the usefulness of brainradiotherapy after chemotherapy are therefore still matters of debate.Recently, several authors have reported a relatively high incidence of lateneurological sequelae after PCL treatment. Conclusions:The optimal treatment of PCL patients remains to bedefined. Large cooperative international phase III trials are now required todefine and improve the optimal treatment of PCL and reduce its sequelae.

    Notes: Abstract Background:Treatment strategies in Hodgkin's disease (HD) arechanging fundamentally over the last decades. Both radiotherapy andcombination chemotherapy are effective treatment modalities. However, theoptimal choice of treatment or combinations of treatment is still debated fordifferent prognostic groups. Patients and methods:The German Hodgkin's Lymphoma Study Group(GHSG) initiated randomized clinical trials since 1978. Over the past 20years, more than 6000 patients with HD in all stages were randomized, treatedand followed by the GHSG. Patients are now being recruited from more than 300clinical centers. Results:As a consequence of different clinical trials, it is nowthe policy of the GHSG to tailor treatment to the individual risk of patients,giving favorable patients less intensive and less toxic therapy thanunfavorable patients. The treatment for early and intermediate stage HDbecomes quite similar with few cycles of polychemotherapy followed by involvedfield irradiation. In advanced stage HD, the introduction of dose intensifiedchemotherapy (BEACOPP), has improved treatment results and thus willsubstitute the MOPP or ABVD regimens. Conclusions:Although most of the patients with HD will be curedby modern treatment stategies, several questions are still subjects of ongoingclinical trials: 1) which chemotherapy regimen in which quantity will be thebest with respect to efficacy and toxicity and 2) which dose and field sizeof radiotherapy is adequate within the combined modality.

    Notes: Abstract Purpose:To determine the safety and activity of LY231514(ALIMTA™, MTA, pemetrexed disodium, Eli Lilly and Co.,Indianapolis, IN) in chemotherapy-naïve patients with advanced pancreaticcancer. Patients and methods:Patients with unresectable or metastaticpancreatic cancer received LY231514 600 mg/m2 as a 10–minuteinfusion every three weeks. Results:Forty-two patients were enrolled in this phase II trial.The median age was 60.3 (range 37–77) years; 79% had metastaticdisease. Neutropenia was common (40% of patients ≥ grade 3) butinfectious complications were rare. Significant anemia or thrombocytopeniaoccurred in 〈20% of patients. Non-hematologic toxicities includedgrade 2 or 3 skin reaction which was ameliorated by dexamethasone. Elevationsof bilirubin or transaminases were infrequent (〈25% of patients) anddid not require dose reductions or treatment delays. Thirty-five patientsreceived two cycles of therapy and were evaluable for response. One complete(duration 16.2 months) and one partial (duration 6.9 months) were observedresulting in an objective response rate of 5.7% for evaluable patients.In addition, 17 patients (40%) had stable disease that lasted ≥6months in 5 patients. The median survival was 6.5 months, with 28% ofpatients alive at one year. Conclusions:LY231514 is a well-tolerated agent with minimalobjective antitumor activity in pancreatic cancer. The median and one yearsurvival times, which may be important indicators in phase II trials of newagents, are of interest. Combination trials of LY231514 in pancreatic cancerare planned.

    Notes: Abstract Background:Gemcitabine (Gemzar®) and 5-fluorouracil (5-FU)plus folinic acid (FA) both have proven activity in the treatment of patientswith advanced pancreatic cancer. The present study was initiated toinvestigate the efficacy of gemcitabine in combination with 5-FU–FA. Patients and methods:Thirty-eight patients, median age 60 years(range 34–70) with inoperable, stage IV, pancreatic cancer were enrolledinto the study and treated on an outpatient basis. All except one patientreceived at least one cycle of treatment with gemcitabine (1000mg/m2), followed by FA (200 mg/m2) and 5-FU (750mg/m2) administered as a 24-hour continuous infusion on days 1, 8,15 and 22 of a 42-day schedule. No patient had received prior chemotherapy orradiotherapy. All 38 patients were assessed for efficacy, toxicity and timeto progressive disease. Results:Two patients (5%), achieved a partial response andthirty-four patients (89%) achieved stable disease. There were twoearly deaths (≤4 weeks). The median time to progression was 7.1 months(range 0.4–18.1+; 95% confidence interval (95% CI):5.3–7.9 months). Three patients had a progression-free interval ofgreater than 12 months and 12 of 38 patients (32%) survived longer than12 months. The median overall survival was 9.3 months (range 0.5–26.5;95% CI: 7.3–13.0 months). The incidence of grade 3 and 4toxicities was low. Conclusions:The combination of gemcitabine and 5-FU–FA isactive and well tolerated and seems to offer an improvement inprogression-free interval over both gemcitabine monotherapy and 5-FU–FAtherapy.

    Notes: Abstract Background:Hepatic arterial chemotherapy for liver metastases ofcolorectal cancer is still under discussion. Mainly because of the technicalcomplications of this mode of treatment and the lack of a survival benefit inrandomized studies. We performed an analysis of hepatic arterial5-fluorouracil (5-FU) chemotherapy in 145 consecutive patients treated at asingle institution. Patients and methods:One hundred forty-five patients withinoperable liver metastases from colorectal cancer were included. 5-FU, 1000mg/m2/day continuous infusion for five days every three weeks, wasdelivered in the hepatic artery by percutaneous catheter or arterial accessdevice. Results:The response rate was 34% for all patients,40% in patients with extrahepatic disease, and 15% in patientswith i.v. 5-FU-based pretreatment. TTP and OS for all patients were 7.5 and14.3 months, respectively. In patients with extrahepatic disease or i.v.5-FU-based pretreatment, OS was significantly shorter compared to patientswithout extrahepatic disease or 5-FU-based pretreatment (9.7 vs. 19.3 monthsand 10.1 vs. 17.4 months, respectively). forty-seven percent of patientsstopped treatment because of a complication. Complications most often seen inpatients with arterial ports were hepatic artery thrombosis (48%) anddislocation of the catheter (22%). Conclusions:The results of our analysis are in line with previousphase III studies. Extrahepatic disease and i.v. 5-FU-based pretreatment wereprognostic for reduced OS. The complication rate of hepatic arterial deliverywas worrisome, although, no negative impact on survival could be established.There is a strong need for improvement of hepatic arterial delivery methodsbefore further evaluation of hepatic arterial 5-FU will be worthwhile.

    Notes: Abstract Background:Among the 566 patients with follicular lymphomas (FL)included in the GELF 86 prospective trials from October 1986 to September1995, 372 with progressive/relapsing disease were analyzed retrospectively toidentify prognostic factors at first relapse. Patients and methods:For progressive FL, patients received mono-(22%) or polychemotherapy (78%) followed by high-dose therapy(HDT) with ASCT for 83 patients (22%). The median time toprogression from initial treatment was 23 months (range 3–102 months)and 24% of documented patients (52 of 217) had histologicaltransformation (HT). Salvage therapy produced an overall response in64% of patients and the five-year survival from progression was42%. Results:For patients who underwent HDT with ASCT compared tostandard treatment, five-year freedom from second failure was at 42%vs. 16% (P = 0.0001) and five-year survival was58% vs. 38% (P = 0.0005), respectively. Thebenefit of HDT and ASCT remained if we consider only patients less than 65years (five-year survival at 60% vs. 40%; P =0.001). Multivariate analysis of parameters significant according tounivariate analysis found that no ASCT at first progression, age at relapse〉50 years, progression on-therapy were adversely significant onsurvival. Conclusions:HDT with ASCT compared to standard treatmentprolonged remission and survival after first progression of FL patients.

    Notes: Abstract Background:It has been shown that irinotecan is superior toinfusional 5-fluorouracil (5-FU) in patients with advanced colorectal cancerafter 5-FU failure. In a recent trial, median survival was 10.8 months forpatients treated with irinotecan, compared to 8.5 months in patients receivinginfusional 5-FU. Considering the statistically significant but clinicallyrelatively small advantage of irinotecan over 5-FU, cost effectiveness shouldalso be part of treatment decision. Purpose:To relate the costs of each management approach tooverall survival in patients with metastatic colorectal cancer. Patients and methods:The healthcare costs and medical benefits(treatment-added survival) of second-line chemotherapy in patients (infusional5-FU: 129, irinotecan: 127) were compared. Data on overall survival were drawnfrom a multicenter randomised trial that compared infusional 5-FU (continuousinfusion, AIO, or LV5-FU2 regimens) to irinotecan alone. Costs were derivedfrom the accounting system in two university hospitals in Paris, France. Results:The range in total healthcare costs was 14,135 to 12,192US$ patient between management approaches, with irinotecan chemotherapycosting most and 5-FU-continuous infusion least. If survival was included asa treatment benefit, the cost-effectiveness ratio of irinotecan over 5-FUranged from 9,344 to 10,137 US$ per year of added survival. Conclusions:The least expensive management for metastaticcolorectal was 5-FU infusion but the additional cost of irinotecan wasbalanced by the added months of survival, with a cost-effectiveness ratioclose to that of other cancer treatments.

    Notes: Abstract Background:There were approximately 12,500 cases of esophageal carcinoma diagnosed in the US in 1992 and 12,200 deaths. The impact of chemotherapy on patients with metastatic disease is marginal with a median survival of only five months. Gemcitabine (LY188011,2,2,–difluorodeoxycytidine: dFdC), an analog of cytosine arabinoside (ara-C), is a pyrimidine antimetabolite. Gemcitabine has shown interesting clinical activity in initial phase II clinical trials in a variety of malignancies, including the aerodigestive malignancies, squamous-cell carcinoma of the head/neck and both non-small-cell and small-cell lung cancer. Patients and methods:A total of 21 patients with chemotherapy-naïve metastatic esophageal carcinoma were entered. Nineteen patients were evaluable for toxicity and seventeen patients were evaluable for response. Gemcitabine was administered intravenously at 1250 mg/m2 over 30–60 minutes on days 1, 8, and 15 followed by 1 week of rest. This four-week schedule defined a cycle of treatment. Patients may have received a maximum of six cycles. Results:Gemcitabine was well tolerated with minimal non-hematologic toxicity and grade 3–4 anemia, granulocytopenia, and thrombocytopenia occurring in 10.5%, 21%, and 0% of patients, respectively. No responses were seen in the seventeen evaluable patients. Conclusions:At the dose and schedule studied it would appear that gemcitabine has no activity in patients with chemotherapy-naïve esophageal carcinoma.

    Notes: Abstract  With the widespread introduction of preoperative radiotherapy for rectal cancer and the development of transanal endoscopic microsurgery for selected early lesions, preoperative radiological staging of these tumours has taken on increasing importance. This study is a systematic review to evaluate computed tomography (CT), endorectal sonography (ES) and magnetic resonance imaging (MRI) as preoperative staging modalities in rectal cancer. A Medline-based search identifying studies using CT, ES, or MRI in preoperative staging of rectal cancer between 1980 and 1998 was undertaken. The list of papers was supplemented by extensive cross-checking of citation lists. Studies were included if they met predetermined criteria. Data from the accepted studies were entered into pooled tables comparing radiological and pathological staging results for each modality both in determining bowel wall penetration and involvement of lymph nodes. Accuracy, sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio were determined for the pooled results. Eighty-three studies from 78 papers including 4897 patients met the inclusion criteria. In determining the wall penetration of the tumour the values for sensitivity for CT, ES, MRI and MRI with endorectal coil were 78%, 93%, 86% and 89%; for specificity 63%, 78%, 77% and 79%; and for accuracy 73%, 87%, 82% and 84%, respectively. In determining the nodal involvement by tumour the sensitivity values for CT, ES, MRI and MRI with endorectal coil 52%, 71%, 65% and 82%; for specificity 78%, 76%, 80% and 83%; and for accuracy 66%, 74%, 74% and 82%, respectively. MRI with an endorectal coil is the single investigation that most accurately predicts pathological stage in rectal cancer.

    Description / Table of Contents: Zusammenfassung. Im Rahmen einer prospektiven Beobachtungsstudie wurden die perioperativen Ergebnisse der Plug-und-Patch-Reparation bei Patienten ≥ 65 Jahre untersucht und zusätzlich bei 34 konsekutiven Patienten die Lebensqualität vor und 3 Monate postoperativ standardisisiert mit Hilfe der Short Form (SF) 36 – einem validierten Lebensqualitätsbogen – erhoben. Von August 1994 bis Februar 1999 wurden 147 Patienten mit einem Durchschnittsalter von 73 ± 5 Jahren (65–92 Jahre) in der Plug-und-Patch-Technik zumeist in Lokalanaesthesie (LA: n = 124; 84 %, ITN: n = 23; 16 %) operiert. Die präoperativen Risikofaktoren waren vor allem Alkoholkonsum, Hypertonus, Diabetes mellitus, coronare Herzerkrankung, Nikotinkonsum, cerebrale Erkrankungen, Hyperlipidämie und pulmonale Erkrankungen. Nach anaesthesiologischer Einschätzung bestand in der Mehrzahl ein Stadium ASA II (ASA I: n = 14; 9 %, ASA II: n = 82; 56 %, ASA III: n = 51; 35 %). Die durchschnittliche Operationszeit betrug 41 ± 17 Min. (26–73). Intraoperative Komplikationen traten nicht auf, postoperative Komplikationen bestanden vor allem in oberflächlichen Wundhämatomen (n = 6; 3,7 %), und -infektionen (n = 1; 0,6 %), Seromen (n = 7; 3,8 %), Harnverhalt (n = 3; 1,8 %) sowie ilioinguinalem Schmerzsyndrom (n = 3; 1,8 %). Der postoperative Schmerzmittelbedarf betrug 4,9 ± 1,8 g Novalgin®über durchschnittlich 4 ± 3 Tage. Die Dauer des postoperativen Klinikaufenthaltes lag bei 2 ± 1 Tagen, die Einschränkung alltäglicher Verrichtungen bei 6 ± 3 Tagen. Bei der klinischen Nachuntersuchung ergab sich in allen Fällen ein regelrechter Befund ohne Hinweis auf ein Rezidiv oder Spätkomplikationen. Bei der Lebensqualität zeigte sich 3 Monate postoperativ eine signifikante Verbesserung (p 〈 0,05) in den Dimensionen: physische Funktion, Schmerz, Vitalität und soziale Funktion im Vergleich zu den präoperativen Werten. Tendentiell günstiger aber nicht signifikant waren postoperativ die Dimensionen Rolleneinschränkung sowie psychische und globale Gesundheit.
    Notes: Abstract. In a prospective study the perioperative results of plug-and-patch repair were investigated in patients ≥ 65 years, and quality of life was assessed using the SF36 preoperatively and 3 months after the procedure in 34 consecutive patients. From August 1994 to February 1999 147 patients with a mean age of 73 ± 5 years (65–92 years) were operated on using the plug-and-patch technique, mostly under local anesthesia (LA: n = 124, 84 %, ITN: n = 23, 16 %). Preoperative risk factors were alcohol consumption, hypertonus, diabetes mellitus, ischemic heart disease, smoking, cerebrovascular disease, hyperlipidaemia and pulmonary disease. Most of the patients were ASA II (ASA I: n = 14, 9 %, ASA II: n = 82, 56 %, ASA III: n = 51, 35 %). No intraoperative complications occurred, postoperative complications consisted of superficial wound hematoma (n = 6, 3.7 %) and infection (n = 1, 0.6 %), seroma (n = 7, 3.8 %), urinary retention (n = 3, 1.8 %) and ilioguinal pain syndrome (n = 3, 3.8 %). The total amount of postoperative analgesic consumption was 4.9 ± 1.8 g Novalgin for about 4 ± 3 days. The duration of postoperative hospitalization was 2 ± 1 days and limitation of daily activities 6 ± 3 days. Clinical examinations after 3 months revealed no recurrence or late complications. Investigation of quality of life showed a significant improvement in the SF36 domains of physical activity, pain, vitality, and social functioning after the operation. No significant change was observed for physical, emotional, and global health.

    Description / Table of Contents: Abstract. This study investigated multiple trauma patients, who were injured between 1991 and 1995 and treated in our department. The aim of this study was to identify the determinants of quality of life after multiple trauma. From a total of 186 patients 173 (93 %) were examined. The patients were asked to rate their quality of life according to the Nottingham Health Profile (NHP) and to a visual analogue scale (VAS). The VAS and the NHP isolated the age of the patients, the duration of artificial respiration, and the duration of rehabilitation as the predictors for a reduced overall quality of life. These results show that quality of life after multiple trauma not only depends on the severity of injury but also on demographic and psychosocial factors.
    Notes: Zusammenfassung. Ziel dieser Studie war es, Prädikatoren zu identifizieren, die die erreichbare Lebensqualität polytraumatisierter Patienten nach Abschluß ihrer klinischen und rehabilitativen Therapie determinieren. Es wurden 173 Patienten nachuntersucht, die in den Jahren 1991–1995 ein Polytrauma per definitionem erlitten hatten. Die posttraumatische Lebensqualität der Patienten wurde mit den international etablierten Meßinstrumenten Nottingham Health Profile (NHP) und einer visuellen Analogskala (VAS) bewertet. Über die VAS und den NHP ließen sich global das Alter der Patienten zum Zeitpunkt der Polytraumatisierung, die Beatmungsdauer und die Rehabilitationsdauer als hochsignifikante Determinanten der posttraumatischen Lebensqualität differenzieren. Diese Ergebnisse zeigen, daß die erreichbare Lebensqualität nach Polytrauma nicht nur von der Schwere der Verletzungen, sondern auch von vorbestehenden, therapeutisch nicht zu beeinflussenden demographischen und psychosozialen Daten abhängig ist.

    Description / Table of Contents: Summary In addition to the motor symptoms of Morbus Parkinson, a number of cognitive and emotional changes take place. The diagnosis of these concomitant symptoms has received increasing attention in research and clinical practice. Global rating scales offer economical advantages but generally do not satisfy the requirements of psychometric criteria, and they do not suffice in light of the multidimensional symptoms of the disease. Based on recent research results, recommendations from the CAPSIT protocol (Core Assessment Program for Surgical Interventional Therapies) for diagnosis of neurosurgically treated Parkinson's patients, and the restraints of everyday clinical work, we propose a standardized neuropsychological diagnostic routine. It includes diagnostic methods that are in use internationally and so timesaving and easily accessible that they can be considered suitable for routine diagnostics. Data comparison among various treatment centers can thus take place more easily. We have included only methods that differentiate well and whose test criteria offer a basis for thorough consultation as well as planning and evaluation of multidimensional therapy.
    Notes: Zusammenfassung Neben den motorischen Symptomen treten beim Morbus Parkinson eine Reihe kognitiver und emotionaler Veränderungen auf. Die Diagnostik dieser Begleitsymptome hat in den letzten Jahren nicht nur im Bereich der Forschung, sondern auch in der klinischen Praxis zunehmend an Bedeutung gewonnen. Globale Ratingskalen genügen trotz ihrer ökonomischen Vorteile in der Regel nicht den Anforderungen psychometrischer Testgütekriterien und werden der Multidimensionalität der Erkrankung nicht gerecht. Basierend auf dem aktuellen Stand der Forschung, den Empfehlungen des CAPSIT-Protokolls zur Diagnostik neurochirurgisch behandelter Parkinsonpatienten sowie den Erfordernissen der klinischen Praxis wird eine Testbatterie zur standardisierten neuropsychologischen Routinediagnostik vorgeschlagen. Sie umfasst diagnostische Verfahren, die zeitökonomisch, gut zugänglich und international verbreitet sind, um in der Routinediagnostik eingesetzt werden zu können und den Austausch zwischen verschiedenen Zentren zu vereinfachen. Es wurden nur Verfahren berücksichtigt, deren Differenziertheit und Testgüte Grundlage für eine fundierte Beratung sein können sowie solche, die für die Planung und Evaluation einer multidimensionalen Therapie geeignet sind.

    Description / Table of Contents: Abstract Available data on the epidemiology of interstitial cystitis (IC) are heterogeneous. Its prevalence ranges between 16 and 510 females/100,000 inhabitants and the incidence at 1.2–2.6/100,000 females with a mean age of 42–52 years. The disease tends to affect women (female:male ratio 9–10:1) and Caucasians (〉90%). The quality of life of patients suffering from IC is reduced to a significant degree in almost every aspect (work, social events, leisure activities). Financial expenses (medical as well as economical) associated with the disease are considerable. There is an enormous need to promote IC education and research in order to support affected patients effectively in the future.
    Notes: Zusammenfassung Die vorliegenden Daten zur Epidemiologie der interstitiellen Zystitis sind sehr heterogen. Die Prävalenz beträgt 16–510 Frauen/100.000 Einwohner, die Inzidenz liegt zwischen 1,2–2,6 /100.000 Frauen mit einem mittleren Alter bei Diagnosestellung von 42–52 Jahren. Die Geschlechterverteilung bevorzugt das weibliche im Verhältnis zum männlichen Geschlecht (9–10 Frauen/1 Mann) mit einer ethnischen Bevorzugung der Kaukasier (〉90%). Die Lebensqualität der betroffenen Patienten ist in fast allen Lebensbereichen (Arbeit, Soziales, Freizeit) signifikant eingeschränkt. Die Kosten (sowohl medizinisch als auch volkswirtschaftlich) sind erheblich. Es besteht ein enormer Weiterbildungs- und Forschungsbedarf, um durch einen besseren Kenntnisstand den Patient(inn)en mit IC wirkungsvoll helfen zu können.

    Description / Table of Contents: Abstract It is important to reflect back on the enormous changes that have taken place in society over the past century that have affected the quality of life of disabled persons and societal attitudes towards disability. Although great progress has been made, these people remain marginalized and disadvantaged, and despite all the efforts of volunteers, professionals, and governments, we cannot categorically state that they are fully socially integrated. The term disability continues to carry an enormous stigma, and therefore it is important to examine the concept of social integration and the issues around it as they affect disabled persons and the role of the International Paralympic Committee (IPC) movement in achieving this end.
    Notes: Zusammenfassung Nach Ablauf des letzten Jahrhunderts ist es wichtig auf die enormen gesellschaftlichen Veränderungen zurückzublicken und darauf, wie dieser Wandel die gesellschaftlichen Einstellungen gegenüber Behinderungen und die Lebensqualität von Behinderten verändert hat. Obwohl große Fortschritte gemacht wurden sind Behinderte immer noch eine benachteiligte Randgruppe; trotz aller Anstrengungen von Freiwilligen, Fachpersonal und Regierungen kann man noch nicht behaupten, dass sie voll gesellschaftlich integriert sind. Der Begriff “Behinderung” beinhaltet weiterhin ein großes Stigma. Deshalb ist es wichtig, das Konzept und die verschiedenen Aspekte der sozialen Intergration von Behinderten zu prüfen und die Rolle des Internationalen Paralympischen Kommittees (IPC) zur Verwirklichung dieser Ziele darzustellen.

    Description / Table of Contents: Abstract From a group of 41 consecutive patients receiving an endoprosthetic knee replacement 35 patients underwent complete pre- and postoperative documentation of life quality in the short term follow-up. The comparison of pre- and postoperative life quality assessment with the SF-36 form showed significant differences on the 5% level for the categories “somatic pain” and “psychological wellness”. The parameter “somatic functionality” showed with a P-value of 0.0616 almost significant improvement. The other parameters also showed improved values without reaching statistical significance. In summary, after implantation of a total knee replacement an improvement of life quality can be documented.
    Notes: Zusammenfassung Aus einem Gesamtkollektiv von 41 nacheinander operierten Patienten konnten bei 35 Daten hinsichtlich der allgemeinen Lebensqualität im kurzfristigen Verlauf dokumentiert werden. Bei der Untersuchung der prä und post-operativen Lebensqualität mit Hilfe des SF-36-Scores zeigten sich auf dem 5-%-Niveau eine signifikante Verbesserung in den Kategorien “Körperliche Schmerzen” und “psychisches Wohlbefinden”. Mit einem P-Wert von p = 0,0616 kann eine fast signifikante Verbesserung in der körperlichen Funktionsfähigkeit konstatiert werden. Weitere 5 untersuchte Unterpunkte zeigten keine signifikante Verbesserung, jedoch bessere Werte bei den errechneten Mittelwerten. Zusammenfassend ist festzustellen, daß die Implantation einer Knieendoprothese zu einem deutlichen Gewinn in der Lebensqualität des kranken Menschen führt.

    Notes: Abstract Patients with metachronous liver metastasis after curative resection of gastric carcinoma generally have a poor prognosis, even when recurrence is confined to the liver. We report a patient in whom hepatic arterial infusion therapy with bolus low-dose cisplatin (CDDP) and continuous 5-fluorouracil (5-FU) was effective against large metastases confined to the liver. An 83-year-old man was admitted with huge liver metastases from gastric carcinoma. Intra-arterial bolus injection of low-dose CDDP (5 mg) and continuous intra-arterial infusion of 5-FU (250 mg/day for 7 days) was started. After four courses of this arterial infusion therapy, computed tomography scans revealed shrinkage of the liver metastases. He was followed-up as an outpatient and continued to receive the arterial infusion therapy once every 4 weeks. Throughout the course of the chemotherapy, a partial response of the liver metastases was maintained. The patient had an improved quality of life after starting the chemotherapy, and he survived for 16 months from the commencement of the therapy. Arterial infusion therapy with bolus low-dose CDDP and continuous 5-FU may be recommended for patients with isolated hepatic recurrence of gastric carcinoma.

    Notes: Abstract  We describe a case of plant-thorn synovitis of the elbow resulting from a thorn injury. This caused recurrent pain and swelling of the elbow over a 3-month period. A magnetic resonance imaging examination was initially requested to exclude septic arthritis, and demonstrated a joint effusion, synovitis, and a 2-cm linear opacity embedded in the synovium. Ultrasound was performed prior to surgery to confirm these findings and provide accurate localization of the thorn fragment, later removed at surgery. To our knowledge this is the first example of this condition that has been confirmed by radiological imaging prior to surgery.

    Notes: Abstract  Objective. To define the possible mechanism of posture-dependent symptoms of spinal stenosis by measuring the effect of low back posture on morphologic changes of the intervertebral discs and spinal canal in healthy young people. Design.Twenty healthy young volunteers underwent magnetic resonance imaging while supine with their spine in neutral, flexed, extended, and right and left rotational positions. The axial MR images at the middle of the intervertebral discs of L3–4 and L4–5 were analyzed to measure the difference in the size and shape of the intervertebral discs and spinal canal in each posture. Results.  Extension or rotation decreased the sagittal diameters and cross-sectional areas of the dural sac and spinal canal and increased the thickness of the ligamentum flavum, whereas flexion had the opposite effects. The gap between the convex posterior disc margin and the anterior margin of the facet joint on each side, represented as the subarticular sagittal diameter, increased with flexion and decreased with extension or rotation. The direction of rotation did not result in asymmetry of the subarticular sagittal diameter, but right rotation caused thickening of the right ligamentum flavum, and vice versa. The shape and dimensions of the disc did not change significantly according to the positions of the low back. Conclusions.With extension or rotation, the thickness of the ligamentum flavum increased and the posterior margin of the intervertebral disc was approximated to the facet joint without any change in shape and size of the disc. These phenomena result in a decrease in the size of the spinal canal and dural sac in extension or rotation postures in young healthy people without disc degeneration, and may explain the posture-dependent symptom of spinal stenosis.

    Notes: Abstract  Complete rupture of the hamstring muscles is a rare injury. The proximal musculo-tendinous junction is the most frequent site of rupture. We present two cases of complete rupture of the distal semimenbranosus tendon, which clinically presented as soft-tissue masses. MR imaging permitted the correct diagnosis. There has been only one other such case reported.

    Notes: Abstract  We report on a 69-year-old woman with a solid variant of aneurysmal bone cyst (solid ABC) in the left humerus with a pathological fracture. Radiographically, the lesion exhibited a relatively well-defined osteolytic lesion in the diaphysis of the left humerus. On magnetic resonance (MR) imaging, the medullary lesion exhibited a homogeneous signal intensity isointense with surrounding normal muscles on the T1-weighted images and a mixture of low and high signal intensity on the T2-weighted images. Contrast-enhanced T1-weighted images revealed diffuse enhancement of the entire lesion. The pathological study showed a proliferation of fibroblasts, histiocytes, chronic inflammatory cells and numerous multinucleated giant cells in a collagenous matrix. Abundant osteoid formation in the matrix was observed, but the cells were devoid of nuclear atypia. Aneurysmal cystic cavities were absent. A review of the English literature found 22 cases of solid ABC of the long bones.

Radiographically, the lesion was a well-defined osteolytic lesion with marginal sclerosis. The CT images demonstrated a well-defined osteolytic lesion with partial cortical breakthrough. T1-weighted MR images showed a hypointense lesion, while T2-weighted images revealed hyperintense areas, with internal, hypointense septa. Gadolinium-enhanced T1-weighted images showed lattice-like enhancement of the lesion.

    Notes: Abstract  Objective. To document the imaging characteristics of subcutaneous and musculoskeletal sparganosis. Design and patients. Ten patients with musculoskeletal sparganosis were examined, with a variety of imaging modalities including MRI (n=6), ultrasonography (n=8), plain radiography (n=7) and CT (n=1). Pathologic correlation was carried out in all cases. Results. Nine lesions involved soft tissues, of which seven were in the thigh, two in the trunk and one involved a vertebral body. The majority of the lesions in soft tissue were confined to the subcutaneous layer but two extended deep into underlying muscles. Sonography revealed low-echoic serpiginous tubular tracts (8/8), and an intraluminal echogenic structure (4/8). MRI revealed multiple serpiginous tubular tracts and peripheral rim enhancement. Two patients showed perilesional soft tissue edema. Pathologically, the lesion consisted of a larva surrounded by three layers of inflammation: an inner epithelioid granulomatous cell layer, middle chronic inflammatory cell layers, and an outer fibrous layer. Conclusion. The study suggests that if serpiginous tubular tracts are seen at imaging studies, musculoskeletal sparganosis should be included in the differential diagnosis.

    Notes: Abstract  Objective. To assess the accuracy and utility of magnetic resonance (MR) imaging in the detection and grading of pectoralis major muscle and tendon tears. Design and patients. A retrospective review was carried out of 10 patients referred for MR imaging for suspected pectoralis muscle injury and possible operative therapy. The pectoralis muscle and tendon were imaged using thin (3–4 mm) axial sections with a variety of sequences combined for anatomical delineation (T1-weighted SE or PD SE) and fluid detection (T2-weighted SE, T2-weighted FSE with fat suppression, or STIR). Surgical correlation was available in six patients. Clinical follow-up was available in four patients treated by nonoperative therapy. Results. MR imaging identified five complete tears, four partial tears and one normal tendon. One complete and one partial tear were at the myotendinous junction. The remaining seven injuries were at the enthesis. Surgical correlation consisted of five complete tears and one partial tear. One complete and one partial tear were at the myotendinous junction with the remaining four complete tears at the enthesis. The MR interpretation and surgical findings were in agreement in all six cases. All four patients treated with nonoperative therapy demonstrated improvement at a clinical follow-up examination, with restoration of function and strength consistent with a healed prior partial injury. Conclusion. MR imaging is accurate and useful in detecting and grading tears involving the pectoralis major muscle and tendon, facilitating the identification of patients with complete tears who are candidates for operative therapy.

    Notes: Abstract  Objective. To review imaging studies of isolated involvement of the sacrum due to tuberculosis and determine the role of imaging in the diagnosis and management of these patients. Design and patients. A retrospective analysis of 15 cases of isolated sacral tuberculosis imaged with MR imaging was performed. The CT images were also reviewed where available, and the various lesion characteristics were identified. We also reviewed the medical records in an attempt to determine the impact of the imaging studies on the management of these patients. Results. Fifteen patients (5 male, 10 female) presented with symptoms of 3–15 months’ duration. Chronic localized backache with muscle spasm was the commonest presenting symptom; discharging sinuses with abscess formation was found in six patients, five of whom were children. MR imaging of the sacrum revealed a hypointense marrow signal on T1-weighted images and hyperintense signal on T2-weighted images in 14 of 15 patients, the S2 vertebra being always involved. CT revealed osteolytic changes in the sacrum in all the five patients in whom CT was performed. All patients showed marked clinical improvement within 1 year of anti-tuberculous chemotherapy. Conclusion. Isolated tuberculosis of the sacrum is uncommon but should be suspected in patients presenting with chronic low backache or children with discharging sinuses/abscesses and showing sacral destruction on CT or MR imaging. MR imaging can identify cases and enables early institution of anti- tuberculous chemotherapy.

    Notes: Abstract  We present a rare case of juxtacortical chondromyxoid fibroma arising in the lesser trochanter of the right femur which corresponds to an apophysis. Radiography showed a well-defined expansive lesion with a sclerotic margin measuring 5×3.5 cm in diameter in the lesser trochanter. On spin echo T1-weighted images, the lesion revealed low signal intensity similar to muscle. On spin echo T2-weighted images, the lesion revealed high heterogeneous signal intensity, which after gadolinium injection showed heterogeneous enhancement. The inner margin of the cortex was intact and adjacent bone marrow was of normal signal intensity. The outer margin of the lesion was also clearly defined and extension into adjacent soft tissue beyond the exophytic cortical outgrowth was not evident.

    Notes: Abstract The impact of bladder removal and urinary diversion for patients' everyday life is largely unknown. The aims of this study were to compare subjective morbidity of ileal neobladder to the urethra versus ileal conduit urinary diversion and to elucidate its influence on quality of life. A total of 102 patients who underwent cystectomy due to a bladder malignancy were included in the study. In 69 patients (67.6%) an orthotopic neobladder and in 33 patients (32.4%) an ileal conduit was performed as urinary diversion. The compliance was 99% and mean follow-up was 37 months. All patients completed two retrospective quality of life questionnaires, namely the QLQ-C30 and a questionnaire developed at our institution to ask for urinary diversion specific items. The questioning and assessment was performed by non-urologists. The results obtained from the validated (QLQ-C30) and our own specially compiled questionnaire clearly demonstrate that patients with an orthotopic neobladder are more able to adapt to the new situation than patients with an ileal conduit. In addition, neobladder to the urethra improves the quality of life because it improves self-confidence, causes better rehabilitation as well as the restoration of leisure, professional, travelling, and social activities, and reduced risk of inadvertent loss of urine. For example, 92.8% of neobladder patients did not feel handicapped at all, and 87% did not feel sick or ill, in contrast to 51.5% and 66.7% of ileal conduit patients, respectively. Of the neobladder patients, 74.6% felt absolutely safe with the urinary diversion in contrast to 33.3% in the ileal conduit group. Only 1.5% of neobladder patients had wet clothes caused by urine leakage during the day, versus 48.5% of ileal conduit patients. Moreover, 97% of our neobladder patients would recommend the same urinary diversion to a friend suffering from the same disease, but only 36% of ileal conduit patients would do so. These results demonstrate that the quality of life is preserved to a higher degree after orthotopic neobladder than after ileal conduit urinary diversion.

    Notes: Abstract Fifty-nine patients with spondylodiscitis (SD) of the thoracic and/or lumbar spine were followed-up clinically and radiologically [X-ray, computed tomography (CT), magnetic resonance imaging (MRI)] over a mean time of 2.2 years (1–6.5 years). All patients without abscess formation (n = 35) were treated conservatively. Out of the group with abscess formation (n = 24) 6 patients were also treated conservatively, 11 were drained under CT control and 7 were operated. At time of diagnosis, “signs of florid inflammation” were seen in 60% of the roentgenograms, in 93% of the CTs and in all of the MRIs. The sensitivity to differentiate between SD with and without abscess formation was 85% by MRI and 69% by CT. “Signs of regressive inflammation” and “signs of increasing osseous consolidation”, essential facts for starting remobilization, could first be seen using CT 6 weeks after onset of therapy. Using MRI these signs were seen with a considerable delay at 12 weeks. Clinically, only 3 of the 59 analyzed patients developed recurrent SD. In conclusion, MRI is the radiological method of choice for establishing the diagnosis of SD, in particular with regard to differentiating between cases with and without abscess formations. In contrast, CT is superior for performing success control after treatment. Therapeutically, conservative, minimal-invasive and operative procedures are not rival but rather complementary.

    Notes: Abstract Gliomas of the optic nerve, although typically of pilocytic (WHO grade I) histology, can present within the spectrum of astrocytic neoplasia including glioblastoma (WHO grade IV). In certain cases, histologic features alone make the distinction between pilocytic and diffuse astrocytomas difficult. We reviewed 22 cases of optic nerve gliomas, 19 of which were pilocytic astrocytomas (PA), and 3 of which were diffuse, non-pilocytic astrocytomas. The cases were evaluated for their clinical course, radiographic appearance, histologic grade, and proliferation indices as detected by MIB-1 (Ki-67) and p53 antibodies. Of the 19 PA, 14 showed no tumor growth by magnetic resonance imaging, and had Ki-67 and p53 labeling indices (LI) of 〈 1%. The other 5 PA exhibited aggressive behavior manifest by marked diffuse infiltrative tumor growth causing death in 2 patients, 1 of whom was diagnosed with neurofibromatosis type 1 (immunoperoxidase and radiographs not available), and marked local growth with an average time to growth of 39.3 months, a Ki-67 LI of 2–3%, and a p53 LI of 〈 1% in three others. Three of the five aggressive PA histologically demonstrated a finely reticulated pattern, a pattern that appears as an exaggeration or expansion of the normal neuroglia of the optic nerve, and may simulate a diffuse low-grade astrocytoma. Two demonstrated the coarsely reticulated pattern, with the biphasic and microcystic pattern typical of PA. Three diffuse astrocytomas (2 anaplastic astrocytomas and 1 glioblastoma) originated clinically and radiographically from the optic nerve, and revealed a Ki-67 LI of 2–12%, a p53 LI of 2–8%, and an average time to growth of 8 months. We conclude that the majority of PA of the optic nerve are non-aggressive, stabilize radiographically, and have Ki-67 and p53 LI 〈 1%. However, a subpopulation of PA has a propensity for aggressive behavior, and are identified by a Ki-67 LI of 2–3% and a p53 LI of 〈 1%. Diffuse astrocytomas have both Ki-67 and p53 LI 〉 2%. Thus, in cases of aggressive optic nerve tumors in which the histologic review of biopsy material cannot confidently confirm the diagnosis of pilocytic or diffuse fibrillary glioma, a p53 LI of 〉 1% appears to favor the diagnosis of diffuse astrocytoma.

    Notes: Abstract  Acute myelofibrosis is a rare, malignant hematological disorder of unknown etiology with an inevitably fatal outcome. Here we present the study of a 63-year-old Caucasian man with acute onset of pancytopenia. Repeated bone marrow biopsies showed dense fibrosis and hypoplastic hematopoiesis raising various differential diagnoses of malignant and nonmalignant conditions. Bone marrow scintigraphy and magnetic resonance imaging (MRI) showed areas suggesting neoplastic infiltration, mainly in both femurs and tibias. Histological examination of a surgical biopsy of the left tibia revealed acute megakaryoblastic leukemia. As the patient refused polychemotherapy, therapy with interferon gamma was initiated but discontinued prematurely because of intolerable side effects. The presented case therefore suggests that the combination of bone marrow scintigraphy and MRI is a valuable diagnostic tool in patients presenting with myelofibrosis of unknown origin.

    Notes: Abstract The authors carried out an anatomic and magnetic resonance imaging study of the architecture of the elevator muscles of the mandible in 169 cadavers. The aim of this study was to define the architectural organization of the human masseter muscle, temporalis and pterygoid muscles. Layered dissections and anatomic sections in different spatial planes showed that the masseter muscle exhibited a typical pennate structure consisting of a succession of alternating musculoaponeurotic layers. The muscle had three well-differentiated parts the superficial, intermediate and deep masseter muscles. The same pattern was constantly found 1) for the superficial masseter, two alternate musculoaponeurotic layers oriented at 60∘ in relation to the plane of occlusion, 2) for the intermediate masseter, a single musculo-aponeurotic layer oriented at 90∘ in relation to the occlusal plane, 3) for the deep masseter, three musculoaponeurotic layers whose general orientation was at 90∘ for the bounding layers and 110∘ for the intermediate layer. The MRI study confirmed the reality of this architectural arrangement.

    Notes: Abstract In this review, a simplified scheme for classification of cortical malformations is introduced and illustrated based on the work of Barkovich et al. [8]. Detailed MRI studies identify cortical malformations as a major cause of epilepsy in children. Two aspects that are becoming increasingly important for the paediatrician are emphasised. First, knowledge of the genetic background of cortical malformations is necessary for appropriate genetic counselling. Although the majority of cortical malformations occur sporadically, recent studies have shown a familial pattern in specific epilepsy syndromes associated with cortical malformations. Second, the epilepsy becomes refractory to the common anti-epileptic drugs in many patients with cortical malformations so that epilepsy surgery should be considered. In this respect, the paediatrician can play a pivotal role in referring candidate patients for further specialised assessment. Conclusion The input of the paediatrician will become crucial to link clinical, genetic and neuro-imaging data in children with the great variety of possible cortical malformations.

    Notes: Abstract Neurological abnormalities in phenylketonuria were described before dietary treatment became possible. These included tremor, clumsiness, epilepsy, spastic paraparesis and occasionally extrapyramidal features. Neurological deterioration after childhood was recognised. Patients with neurological deterioration described recently have been late diagnosed or intellectually impaired or both. No early diagnosed patient who was well treated and of good intellectual outcome has yet shown neurological deterioration after stopping diet but it may happen. Conclusion The fascinating links between pathology, magnetic resonance imaging appearances, magnetic resonance spectroscopy results and clinical features are not yet clearly understood. Patients must understand the possible risks of stopping diet and make their choice. All patients need help, support and follow-up regardless of the choices they make over continuing diet.

    Notes: Abstract. We present the clinical and magnetic resonance imaging findings of a patient who, following treatment for pancreatic non-Hodgkin's lymphoma (NHL), relapsed with apparently isolated involvement of the right masticator space and left psoas muscles. Non-Hodgkin's lymphoma arising from the masticator space muscles is very rare. In addition, simultaneous lymphomatous involvement of multiple discrete skeletal muscle sites, in the absence of disease elsewhere, has previously only been reported in the limb or limb girdle muscles. Lymphoma should be considered as a cause of isolated enlarged skeletal muscles, even when involving such distant sites.

    Notes: Abstract Toxoplasma encephalitis was confirmed by biopsy in three patients with bone marrow (BMT) or peripheral blood stem-cell transplantation (PBSCT). All had MRI before antimicrobial therapy. The intensity of contrast enhancement was very variable. One patient had one large, moderately enhancing cerebral lesion and several smaller almost nonenhancing lesions. The second had small nodular and haemorrhagic lesions without any enhancement. The third had late cerebral toxoplasmosis and showed multiple lesions with marked contrast enhancement. The moderate or absent contrast enhancement in the two patients in the early phase of cerebral toxoplasmosis may be related to a poor immunological response, with a low white blood cell count in at least one patient. Both received higher doses of prednisone than the patient with late infection, leading to a reduced inflammatory response. In patients with a low leukocyte count and/or high doses of immunosuppressive therapy, typical contrast enhancement may be absent.

    Notes: Abstract We present the results ¶of MRI examinations in ten patients with documented Nijmegen ¶breakage syndrome (NBS), aged 1.75–19 years. T1-, Proton-Density- and T2-weighted spin-echo sequences were performed in three planes. All patients showed microcephaly with decreased size of the frontal lobes and narrow frontal horns. In four patients agenesis of the posterior part of the corpus callosum was found, with colpocephaly and temporal horns dilatation. In one patient callosal hypoplasia was accompanied by abnormal cerebrospinal fluid spaces and wide cerebral cortex, suspicious of pachygyria. Sinusitis was present in all ten patients, as a result of primary immunodeficiency. As in ataxia teleangiectasia and other breakage syndromes, patients with NBS show an inherited susceptibility to malignancy and hypersensitivity to X- and γ-radiation. CT is therefore contraindicated in these patients and MRI should be the method of choice for diagnostic imaging.

    Notes: Abstract Our aim was to evaluate the relative diagnostic accuracy of MRI without contrast medium and MRI before and after contrast medium in the assessment of T-staging of laryngeal tumours. We studied 25 men (mean age 51.8, range 41–61) with laryngeal squamous cell carcinomas, using Spin-echo (SE) T1-weighted and fast SE T2-weighted sequences. The T1-weighted sequences were then repeated after gadolinium-diethylene-triaminepenta-acetic acid (Gd DTPA) 0.1 ml/kg. All patients then underwent biopsy and surgery. Two radiologists independently assessed the anonymised images by filling-out two multiple-choice forms, one for each technique, at a 2 week interval. The forms included a judgement concerning tumour identification and infiltration of the anterior commissure, supraglottic region, arytenoid cartilage, Morgagni's ventricle, paraglottic space, thyroid and cricoid cartilages, thyro-hyo-epiglottic space, vocal cords, subglottic region, and epiglottis. Similar forms were filled out by the surgeon and the pathologist after surgery. The sensitivity, specificity and diagnostic accuracy of MRI were unaffected by the use of contrast medium. Since it did not provide additional staging information, its continued routine use in these cases is not justified.

    Notes: Abstract We report a 63-year-old man who had a rare bilateral thalamic glioma. He complained of difficulty with calculations and had mental deterioration. T1-weighted images revealed bilateral thalamic swelling with homogeneous low signal and no contrast enhancement. The tumour, showing decrease of N-acetylaspartate and the presence of lactate on magnetic resonance spectroscopy, was diagnosed as an astrocytoma by stereotactic biopsy.

    Notes: Abstract We report on a young woman with a primary cerebral immunocytoma. Most primary cerebral nervous system lymphomas (PCNSL) are highly malignant undifferentiated B-cell tumours, there are few data on the clinical course, MRI and spectroscopy findings of this rare PCNSL subtype. MRI revealed a radially enhancing tumour with mild perifocal oedema. MR spectroscopy indicated low cell turnover. Slow clinical progression, no significant changes with treatment, and imaging findings were consistent with a low-grade malignant tumour.

    Notes: Abstract The tick-borne encephalitis (TBE) virus gives rise to epidemic encephalitis. Mild forms usually manifest as influenza-like episodes or are clinically silent. MRI is usually normal in TBE. We describe severe TBE in a patient who presented with fever and altered mental status after a tick bite and a specific antibody response to TBE. MRI revealed pronounced signal abnormalities in the basal ganglia and thalamus, without contrast enhancement. These findings coincide well with neuropathological studies of severe nerve cell degeneration with inflammatory cell infiltrates, neuronophagia and reactive astrocytosis in the deep grey matter. We review the literature and discuss the relevant differential diagnosis.

    Notes: Abstract MRI has facilitated diagnostic assessment of the corpus callosum. Diagnostic classification of solitary or multiple lesions of the corpus callosum has not attracted much attention, although signal abnormalities are not uncommon. Our aim was to identify characteristic imaging features of lesions frequently encountered in practice. We reviewed the case histories of 59 patients with lesions shown on MRI. The nature of the lesions was based on clinical features and/or long term follow-up (ischaemic 20, Virchow-Robin spaces 3, diffuse axonal injury 7, multiple sclerosis 11, hydrocephalus 5, acute disseminated encephalomyelitis 5, Marchiafava-Bignami disease 4, lymphoma 2, glioblastoma hamartoma each 1). The location in the sagittal plane, the relationship to the borders of the corpus callosum and midline and the size were documented. The 20 ischaemic lesions were asymmetrical but adjacent to the midline; the latter was involved in new or large lesions. Diffuse axonal injury commonly resulted in large lesions, which tended to be asymmetrical; the midline and borders of the corpus callosum were always involved. Lesions in MS were small, at the lower border of the corpus callosum next to the septum pellucidum, and crossed the midline asymmetrically. Acute disseminated encephalomyelitis and the other perivenous inflammatory diseases caused relatively large, asymmetrical lesions. Hydrocephalus resulted in lesions of the upper part of the corpus callosum, and mostly in its posterior two thirds; they were found in the midline. Lesions in Marchiafava-Bignami disease were large, often symmetrically in the midline in the splenium and did not reach the edge of the corpus callosum.

    Notes: Abstract Knowledge of the exact site of leakage of cerebrospinal fluid CSF leakage is important for planning surgery. We report our experience with myelocisternography with Gd-DTPA. We decided that intrathecal use of this contrast medium was justified in selected cases when other techniques have failed. After we had given detailed information to four patients with CSF leakage, they underwent five examinations. The images were interpreted by comparing those before and after injection. In all cases the contrast medium arrived at the basal cisterns, giving high contrast against adjacent structures. All patients tolerated the examination without complications or any indication of side effects.

    Notes: Abstract Idiopathic granulomatous hypophysitis is a rare inflammatory disease of unknown aetiology; few cases are reported. We review the clinical presentation and radiological characteristics of these cases and our own experience with three new surgical cases, to determine diagnostic criteria. MRI of three cases revealed sellar lesions extending into the chiasmatic cistern. Their shape varied, from dumbbell to spherical and elliptical. All were isointense with the brain on T1-weighted images and gave heterogeneously high signal on T2-weighted images. Contrast enhancement was homogeneous in one case and heterogeneous in another. The pituitary stalk could not be identified. There was no dural enhancement. The sphenoid sinus mucosa was thickened in two cases and normal in one.

    Notes: Abstract We reviewed the CT and MRI of seven patients with primary malignant lymphoma of the maxillary sinus to find if there are characteristic imaging findings suggestive of the disease. The images were analysed for appearance, size, signal, internal characteristics, extent of tumour, bone change and lymph node enlargement. In two patients, the tumour first presented with mucosal thickening. In the remaining five, the tumours were an expansile mass 4–6 cm in diameter at the time of detection. Although it was difficult to distinguish tumour from mucosa or obstructed fluid on CT, T2-weighted MRI enabled us to separate tumour from normal mucosa or fluid. In two patients, the tumours were heterogeneous. Calcification and haemorrhage were observed in one patient. Periantral soft-tissue infiltration was always present, even when tumour appeared as slight mucosal thickening. Posterior extension was seen in all patients. Permeative and lytic bone destruction accompanied most cases of periantral soft-tissue infiltration; mixed destruction and sclerosis was also observed. Mucosal thickening with periantral soft-tissue infiltration may suggest malignant lymphoma of the maxillary sinus in its early form. Various types of bone change may accompany the periantral soft-tissue infiltration.

    Notes: Abstract Among 527 MRI examinations of patients with a suspicion of epilepsy in 5 years, we found 32 cases of hippocampal malrotation (HIMAL). The characteristic features are: incomplete inversion of the hippocampus with and abnormally round shape; unilateral involvement of the whole hippocampus; normal signal intensity and size; blurred internal structure; an abnormal angle of collateral sulcus; abnormal position and size of the fornix; normal size of the temporal lobe; enlargement and particular configuration of the temporal horn, typical of corpus callosum agenesis; and a normal corpus callosum. In 7 cases (22 %) HIMAL occurred together with developmental disorders. It was predominantly seen in men. The clinical features were varied. Based on some MRI features, the presence of developmental disorders, the male predominance, the frequently positive family history, and a review of the literature, we think HIMAL may be the consequence of a mild hemisphere developmental disorder. It is probably not the basic cause of epilepsy in such varied clinical setting, but may be a sign of a developmental disorder and can help in selecting patients for more meticulous investigation. It also may give some new understanding of brain development.

    Notes: Abstract We describe the normal dural enhancement patterns of the sellar region and determine whether the duramater is affected by pituitary macroadenomas. Dural enhancement appeared to be usually abnormal in 20 patients with pituitary macroadenoma compared with 20 control patients, mainly at the planum sphenoidale and carotid sulcus. However dural changes are subtle and their recognition requires knowledge of the normal enhancement patterns. Dural changes, reported in a variety of inflammatory and infectious dural diseases and after surgery, are not specific and may be also seen in pituitary macroadenomas.

    Notes: Abstract To assess the role of virtual endoscopy (VE) in the examination of intracisternal structures and of the inner ear, we studied the anatomy of the labyrinth and internal auditory canal using the original CT slices and VE on the unaffected side in three female and three male patients, age range 3–46 years, with contralateral retrocochlear hearing loss. We also examined seven patients with different pathological findings. VE was performed using an advanced postprocessing program with high- resolution 3D data sets of CT (1–1.5 mm thickness, pitch 1.25) and MRI-CISS-3D (constructive interference in steady state) images of the basal cisterns (1.5 T, slice thickness 0.7–1 mm). VE provides an endoscopic-like view from a given point within the basal cisterns of vessels and nerves (on MRI) or of the structures of the inner ear (on CT). The complex anatomy and pathological changes in the inner ear can be faithfully shown. The main advantage is not basic diagnostic information but demonstration of topographically complex situations, such as the canalicular system of the inner ear, for discussion, preoperative planning and teaching.

    Notes: Abstract Cranial and spinal MRI was carried out at 0.5 or 1.5 T in five patients with spinal dermoid tumours. Free fatty material was appreciated within the normally communicating cerebrospinal fluid pathways in all five cases and in one case fat droplets were also observed within a dilated central canal of the spinal cord. While dissemination of lipid within the subarachnoid space and ventricles is easily understandable, the presence of lipid droplets within the central canal is more difficult to explain, since the central canal is only potential in the adult. When a dermoid tumor is suspected, we recommend MRI of the entire central nervous system, to detect possible leakage of fat from rupture of a cystic portion of the tumour.

    Notes: Abstract We evaluated the feasibility and use of diffusion-weighted and fluid-attenuated inversion-recovery pulse sequences performed as an emergency for patients with acute ischaemic stroke. A 5-min MRI session was designed as an emergency diagnostic procedure for patients admitted with suspected acute ischaemic stroke. We reviewed routine clinical implementation of the procedure, and its sensitivity and specificity for acute ischaemic stroke over the first 8 months. We imaged 91 patients (80 min to 48 h following the onset of stroke). Clinical deficit had resolved in less than 3 h in 15 patients, and the remaining 76 were classified as stroke (59) or stroke-like (17) after hospital discharge. Sensitivity of MRI for acute ischaemic stroke was 98 %, specificity 100 %. MRI provided an immediate and accurate picture of the number, site, size and age of ischaemic lesions in stroke and simplified diagnosis in stroke-like episodes. The feasibility and high diagnostic accuracy of emergency MRI in acute stroke strongly support its routine use in a stroke centre.

    Notes: Abstract Cavernomas fall within the group of angiographically occult lesions and may be found in up to 4 % of the population [1]. They may occur at any age, and with the advent of MRI incidental cavernomas are increasingly identified. The pathogenesis is uncertain. Familial cases are well recognised with a reported prevalence of 10–15 % [2–3]. The incidence of new lesions has been reported at 0.4 lesions per patient per year in cases with familial cavernomas [4]. Presumed cavernomas have been documented following radiation for malignancy [5–6], and sterotactic cerebral biopsy [7]. There have been no previously documented cases of de novo genesis of cavernomas following bacterial meningitis and subdural empyemas.

    Notes: Abstract We compared the sensitivity of T2-weighted spin-echo (FSE) and fast short-tau inversion-recovery (fSTIR) sequences in detection of multiple sclerosis of the spinal cord in 100 consecutive patients with clinically confirmed multiple sclerosis (MS); 86 patients underwent also brain MRI. In all, 310 focal lesions were detected on fSTIR and 212 on T2-weighted FSE, spinal cord lesions were seen better on fSTIR images, with a higher contrast between the lesion and the normal spinal cord. In 24 patients in whom cord plaques were shown with both sequences, the cranial study was normal or inconclusive. Assessment of spinal plaques can be particularly important when MRI of the brain is inconclusive, and in there situations fSTIR can be helpful.

    Notes: Abstract Our aim was to relate MRI findings in patients with severe traumatic brain injury (TBI) to clinical severity and long-term outcome. We studied 37 patients with severe TBI, who were submitted to clinical assessment for disability and cognition and to MRI 60–90 days after trauma. Clinical assessment was also performed 3, 6 and 12 months later. The number and volume of lesions in various cerebral structures were calculated semiautomatically from FLAIR and fast field-echo images. Possible correlations between total and regional lesion volume and clinical deficits were then investigated. The frontal and temporal lobes were most frequently involved. Total lesion volume on FLAIR images correlated significantly with clinical outcome, whereas that on FFE images did not. Regional analysis showed that FLAIR lesion volume in the corpus callosum correlated significantly with scores on disability and cognition scales at the first clinical assessment. FLAIR lesion volume in the frontal lobes correlated significantly with clinical scores 1 year later.

    Notes: Abstract Intracerebral haemorrhage may be visible indefinitely on MRI, due to persistence of haemosiderin in macrophages around the lesion, but it is not clear whether all haemorrhages produce haemosiderin or, if not, what proportion cannot be identified as former haemorrhages on routine MRI. We performed routine MRI (spin-echo T2- and proton-density weighted images) in 116 survivors of moderate to severe head injury, 1–5 years after injury. We reviewed the images blindly and correlated them with CT in the acute stage, to determine how many haemorrhages from the acute stage were identifiable by virtue of haemosiderin deposition on late MRI. Of 106 haemorrhages in 78 patients on CT at the time of injury, 96 (90 %) were visible as haemosiderin on late MRI. Of the old haemorrhages without haemosiderin, seven of ten were in patients where another haemorrhage with haemosiderin was still visible elsewhere in the brain. No patient or haemorrhage features explained the formation or absence of haemosiderin. Thus about 10 % of definite haematomas show no trace of haemosiderin on routine spin-echo MRI. Radiologists should be alerted to supplement routine spin-echo with gradient-echo sequences if there is a reason to suspect, or specifically exclude, prior haemorrhage.

    Notes: Abstract We present a case of vitamin B12 deficiency and subacute combined degeneration in a patient with a gastrectomy. MRI showed high-signal lesions on T2-weighted images in both the posterior and anterior columns, associated with minor thoracic spinal cord expansion. The patient was treated with B12 supplements and clinical improvement was associated with reduction of the size of the lesions on MRI.

    Notes: Abstract The frequency, predisposing factors and clinical consequences of haemorrhagic infarcts and damaged blood-brain barrier as shown by contrast enhancement (CE) in ischaemic cerebral infarcts are controversial. We prospectively compared the sensitivity of CT and MRI to haemorrhagic transformation (HT) and CE. We also wished to investigate the clinical significance of HT and factors possibly associated with it. We studied 36 patients with acute ischaemic infarcts in the middle cerebral artery territory during the first 2 weeks after the ictus. After CT and rating of the neurological deficit on admission, serial examinations with clinical neuromonitoring, contrast-enhanced CT and MRI were done on the same day. The occurrence and severity of HT were correlated with CE, stroke mechanism, infarct size, development of neurological deficits and antithrombotic treatment. The frequency of HT detected by MRI was 80 %. CE usually preceded HT or was seen simultaneously. MRI had a higher sensitivity than CT to HT and CE. Severity of HT was positively correlated with infarct size (P 〈 0.01). HT had no influence on patient's neurological status. Neither the type of antithrombotic treatment nor the stroke mechanism was associated with the severity of HT. No parenchymal haemorrhage occurred.

    Notes: Abstract Phaeohyphomycosis is an uncommon disorder caused by a variety of saprophytic fungi having distinctive morphologic features. Central nervous system infection typically occurs in the absence of predisposing factors and usually manifest symptoms and signs of abscess formation. We describe an otherwise healthy young man whose presentation with cerebral phaeohyphomycosis was subacute meningitis and stroke. Neuroimaging studies revealed multiple parenchymal lesions having the characteristics of recent infarcts; several vascular territories were involved. The nature of these lesions was confirmed histologically at autopsy. To our knowledge, such radiologic appearances have not previously been reported in this condition.

    Notes: Abstract We reviewed the preoperative images of 28 patients with pathologically proven mesial temporal sclerosis, to assess thalamic asymmetry and signal change. A further 25 nonsurgical patients with temporal lobe epilepsy and unequivocal, unilateral changes of mesial temporal sclerosis, and 20 controls, were also reviewed. None of the control group had unequivocal asymmetry of the thalamus. There was an ipsilateral asymmetrically small thalamus in five (18 %) of the surgical group and in three (12 %) of the nonsurgical patients. In four cases there was thalamic signal change. In three patients with thalamic volume loss there was ipsilateral hemiatrophy. All patients with an asymmetrically small thalamus had an asymmetrically small fornix and all but one a small ipsilateral mamillary body.
