    Description / Table of Contents: Summary Brain metastases develop as a late manifestation of renal cell cancer (RCC) and pose an increasing challenge to urologists as a result of the more frequent prolonged survival of patients with advanced RCC. Therapeutic options, including surgical resection and radiotherapy, were analyzed retrospectively to assess survival and to identify factors influencing prognosis in a group of 90 patients treated either by brain metastasectomy (n = 64) or radiotherapy (n = 26). The analysis confirmed that the overall median survival was a disappointing 461 days and the 1-year survival rate was 31 % for patients treated by surgical resection and 310 days and 15 % respectively for patients treated by radiotherapy. However, a subgroup of patients who benefitted significantly from aggressive treatment of metastases could be defined. The following favorable prognostic factors showed a trend toward improved survival: (1) metachronous appearance of brain metastases more than 1 year after nephrectomy (P 〈 0.0001), (2) good patient performance (Karnofsky 〉 70) (P 〈 0.0002), (3) patient's age under 50 years (P 〈 0.05), (4) solitary lesions (P 〈 0.05), (5) minimal or no neurological deficit (P 〈 0.05), and (6) the absence of/or minimal extracranial metastases (P 〈 0.05). No influence of lesion size and localization (infratentorial vs supratentorial) on survival was detected. Surgical treatment of recurrent brain tumors (n = 17) yielded an additional median survival advantage of 8 months as compared to untreated patients (n = 16). Our results suggest that, especially in patients with good prognostic criteria, a radical metastasectomy plus vigorous surgery of local recurrences and, if required, subsequent systemic immuno- or chemoimmunotherapy should be performed. In patients with poor prognosis, stereotactic radiosurgery is recommended for palliation and survival prolongation.
    Notes: Zusammenfassung Die Resektion bzw. Bestrahlung der Hirnmetastasen als Bestandteil eines interdisziplinären Therapiekonzepts bei disseminiert metastasiertem Nierenkarzinom hat angesichts der besseren Therapierbarkeit der systemischen Metastasen neuerdings an Bedeutung gewonnen. Um den eventuell daraus resultierenden Nutzen für die Patienten zu charakterisieren, wurden die klinischen Verläufe von 90 Patienten, die im Zeitraum vom 30. 06. 1977 bis zum 30. 06. 1993 wegen hirnmetastasiertem Nierenzellkarzinom entweder operiert (n = 64) oder bestrahlt (n = 26) wurden, retrospektiv analysiert und der Effekt möglicher prognostischer Faktoren auf das Überleben untersucht. Die Analyse bestätigte zwar grundsätzlich die ausgesprochen schlechte Prognose von Patienten mit Hirnmetastasen, wobei nach operativer Behandlung die Gesamteinjahresüberlebensrate 31 % und das mediane Überleben 461 Tage und nach Bestrahlung 15 % bzw. 310 Tage betrugen. Es konnte jedoch eine Gruppe von Patienten definiert werden, die in besonderer Weise von der Behandlung profitiert hatten. Die beste Langzeitprognose zeigten Kranke 1. im Alter von unter 50 Jahren, 2. in gutem Allgemeinzustand (Karnofsky über 70) (p 〈 0,0002), 3. mit Solitärmetastasen (p 〈 0,05) und 4. langem metastasenfreiem Intervall nach dem Auftreten des Primärtumors bis zur Hirnmetastasendiagnose von 〉 1 Jahr (p 〈 0,0001) sowie 5. keinen bzw. geringgradigen neurologischen Ausfällen und 6. keinen bzw. minimalen extrakraniellen Metastasen.

    Notes: Abstract Peripheral blood samples from 61 patients (36 male, 25 female) with all stages of B-type chronic lymphocytic leukemia (CLL) were studied for MDR1 phenotype using monoclonal antibodies and rhodamine-123 dye exclusion, a functional assay of MDR1 expression. The duration of the disease varied from 1 month to 22 years at the time of initial study. Overall, 74% of the patients were positive for rhodamine-123 exclusion. When analyzed by gender, significantly more men than women were positive (89% versus 48%, p〈0.001). There were more positive men than women for every stage of the disease. Female patients were found to be either MDR1 phenotype positive or negative at any stage of the disease. In contrast, all male patients with early (stages 0–II) disease were MDR1 phenotype positive. One early-stage (stage II) male patient converted from rhodamine-efflux positive to rhodamine-efflux negative as he progressed from stage-II to stage-IV disease. We suggest that some of the differences in disease biology of male versus female CLL patients (women having a more benign course) may be due to gender-dependent differences in drug-resistance gene activity, including MDR1. Our results also emphasize the need to take into account gender in evaluating the clinical course of patients with CLL.

    Notes: Abstract We report ultrasonographic and CT findings in a patient with endometriosis of the bladder wall after cesarean section. Endometriosis is defined as ectopic endometrial tissue which responds to the endocrine changes of the menstrual cycle [1]. The incidence of the condition may be as high as 20% of all menstruating women [2]. The most common locations of endometriosis are in the true pelvis, particularly the fallopian tubes and the ovaries. The sacrouterine ligaments and Douglas' cul-de-sac are also frequently affected. Rarer sites of endometriotic implants include the gastrointestinal tract, urogenital organs, and extraabdominal sites. The diagnosis is suggested by the results of modern imaging techniques and the usually typical clinical findings and is confirmed by histopathology of a surgical specimen. The literature contains few reports on ultrasound and computed tomography (CT) findings in patients with endometriosis [3, 4].

    Notes: Abstract Vascular injuries in lumbar disk surgery, although rare, are serious complications which may be overlooked due to a broad range of clinical manifestations. It is important that surgeons and radiologists be aware of these potentially fatal complications and develop an appropriate symptom-based diagnostic paradigm. We reviewed 8099 consecutive cases of lumbar disk surgery, performed over a 14-year period at a single institution, for postoperative vascular complications. We identified four patients (0.05%) with lumbar disk surgery-related vascular complications: intraoperative lacerations of the abdominal aorta and median sacral artery, an arteriovenous fistula between the left common iliac artery and vein detected 19 days postdiskectomy, and a partially thrombosed aortic aneurysm with an arteriovenous fistula between the aneurysm and the inferior vena cava, diagnosed 11 months after surgery. The majority of cases in the literature of vascular injury in lumbar disk surgery were reported prior to 1965. Diagnostic approaches described in that period do not reflect the great range of diagnostic techniques available today. Angiography remains the gold standard for diagnosis and guidance as to surgical repair. However, a high index of suspicion based on clinical signs and/or the use of sonography or CT is important in the detection of these complications.
