    Notes: BACKGROUND: Pantoprazole is a proton pump inhibitor characterized by a low potential to interact with the cytochrome P450 enzyme system in man. Its effect on intragastric pH following single and repeated oral intake was investigated in comparison to omeprazole by continuous intragastric pH-metry at doses recommended for treatment of peptic ulcer disease. METHODS: Sixteen healthy male subjects underwent two dosing periods. From day 1 to day 7, they were given once daily by mouth 40 mg pantoprazole in one period and 20 mg omeprazole in the other period, according to a double-blind randomized crossover design. Twenty-four-hour intragastric pH was recorded and frequent blood samples for pharmacokinetic analysis were taken on day 1 and day 7. A placebo pH profile was obtained prior to each treatment period. RESULTS: Pantoprazole was significantly more effective than omeprazole with regard to increase in 24-h and daytime pH, following both single (median 24-h pH: 1.45 vs. 1.3, P 〈 0.05; median daytime pH: 1.6 vs. 1.3, P 〈 0.01) and repeated (median 24-h pH: 3.15 vs. 2.05, P 〈 0.01; median daytime pH: 3.8 vs. 2.65, P 〈 0.05) oral intake. As compared to the first dose, repeated administration of both drugs markedly increased the effect on intragastric pH. With pantoprazole, steady- state serum concentrations were obtained after the first dose, but not with omeprazole. Both drugs were well tolerated without relevant changes in vital signs of clinical laboratory parameters. CONCLUSION: Pantoprazole 40 mg is significantly more effective than omeprazole 20 mg in raising intragastric pH.

    Description / Table of Contents: Summary In analogy with high-dose contrast-enhanced CT, there have been a few studies during recent years that have dealt with high-dose paramagnetic contrast dyes in MRI. One reason for these studies was the development of new and low-osmolar contrast agents in the MR field. Depending on the clinical problem, a high-dose contrast study in MRI is rarely indicated: (1) in metastatic disease, MR imaging with high-dose contrast material is indicated when the standard dose study is negative or only shows a solitary cerebral lesion or a number of lesions just suitable for radiosurgery; (2) in patients with malignant glioma the high-dose study allows better definition of the tumor margins. If a radical surgical approach is planned, the diagnostic potential should be fully used; if only a biopsy or subtotal debulking is planned, a standard dose study is enough. (3) in patients with MS, a high-dose study is only recommended within therapeutic trials in which the number of active plaques is a primary variable.
    Notes: Zusammenfassung In Analogie zu Erfahrungen mit der Hochdosiskontrastverstärkung in der CT wurden in den letzten Jahren Untersuchungen zur höheren Dosierung der paramagnetischen Kontrastmittel in der MRT gemacht. Dabei spielte auch auf dem MR-Sektor die Entwicklung von niedrig osmolaren Kontrastmitteln eine Rolle. In Abhängigkeit von der konkreten Fragestellung ist die Hochdosis-KM Gabe im kranialen MRT derzeit nur selten indiziert: 1. Zeigt das MR nach der KM-Standarddosis nur eine singuläre intrazerebrale Metastase oder aber eine Anzahl von Metastasen, bei der die Radiochirurgie gerade noch indiziert ist, ist eine zweite MR-Untersuchung mit einer Gesamtdosis von 0,3 mmol/kg KG zu empfehlen. Dies gilt auch, wenn unter der Standarddosis keine zerebrale Metastase bei malignem Grundleiden sichtbar ist. 2. Bei malignen hirneigenen Tumoren ermöglicht die Hochdosis-KM-Gabe eine bessere Definition der Tumorgrenzen. Wenn eine radikale Operation möglich erscheint, sollten die diagnostischen Möglichkeiten voll ausgeschöpft werden. Ist nur eine Biopsie oder eine subtotale Operation geplant, ist die Standarddosis ausreichend. 3. Bei der multiplen Sklerose ist die Hochdosis KM-Gabe nur in Therapiestudien indiziert, wenn eine der Zielvariablen die Anzahl der aktiven Plaques ist.

    Description / Table of Contents: Summary Purpose: To assess the influence of initial preoperative brain edema in malignant gliomas on regrowth patterns. Subjects and methods: 79 patients with histologically verified supratentorial malignant glioma were prospectively studied by magnetic resonance imaging (MRI) before and every 2–3 months after surgery. The median follow-up time was 11 months. We correlated the configuration of the initial vasogenic edema on T2-weighted images with tumor regrowth patterns on contrast-enhanced T1-weighted images. Results: 35/47 tumor regrowths (75%) imitated the initial edema configuration, while 11/47 occurred within the initial tumor bed; in one case tumor recurrence was multilocal. Conclusion: In glioblastoma, tumor regrowth patterns correlate positively with the configuration of the initial vasogenic brain edema. The initial, „presurgical” peritumoral edema should thus be considered when planning further treatment.
    Notes: Zusammenfassung Fragestellung: Beeinflussen Form und Größe des präoperativen peritumoralen Hirnödems die Rezidiventwicklung bei malignen supratentoriellen Gliomen? Methodik: Prospektiv wurden 79 Patienten mit einem malignen supratentoriellen Gliom mit einem standardisierten MRT-Protokoll untersucht. MRT-Untersuchungen erfolgten vor der neurochirurgischen Operation, möglichst innerhalb der ersten 3 Tage nach Operation und während der Nachbeobachtungszeit in Abständen von 2–3 Monaten. Die mediane Nachbeobachtungszeit betrug 11 Monate. Die initiale präoperative Ödemkonfiguration auf den T2-gewichteten MRT-Aufnahmen wurde mit der Rezidivtumorkonfiguration auf den Kontrastmittel verstärkten T1-gewichteten Aufnahmen verglichen. Ergebnisse: 47 Patienten entwickelten während der Nachbeobachtungszeit ein Rezidiv. Die Konfiguration des Rezidivtumors imitierte in 35/47 Patienten (75%) die initiale präoperative Ödemkonfiguration. Bei 11/47 Patienten entwickelte sich ein lokales und bei einem Patienten ein multilokales Rezidiv. Schlußfolgerungen: Die präoperative Tumorödemkonfiguration im T2-gewichteten MRT-Bild korreliert mit der Rezidivtumorausdehnung. Zukünftige Therapiestudien sollten daher die Ausdehnung des initalen präoperativen Ödems als zusätzlichen prognostischen Faktor mitberücksichigen.

    Notes: Abstract We report our experience in using Guglielmi electrolytically detachable coils (GDC) alone or in combination with other materials in the treatment of intracranial or cervical high-flow fistulae. We treated 14 patients with arteriovenous fistulae on brain-supplying vessels – three involving the external carotid or the vertebral artery, five the cavernous sinus and six the dural sinuses – by endovascular occlusion using electrolytically detachable platinum coils. The fistula was caused by trauma in six cases. In one case Ehlers-Danlos syndrome was the underlying disease, and in the remaining seven cases no aetiology could be found. Fistulae of the external carotid and vertebral arteries and caroticocavernous fistulae were reached via the transarterial route, while in all dural fistulae a combined transarterial-transvenous approach was chosen. All fistulae were treated using electrolytically detachable coils. While small fistulae could be occluded with electrolytically detachable coils alone, large fistulae were treated by using coils to build a stable basket for other types of coil or balloons. In 11 of the 14 patients, endovascular treatment resulted in complete occlusion of the fistula; in the remaining three occlusion was subtotal. Symptoms and signs were completely abolished by this treatment in 12 patients and reduced in 2. On clinical and neuroradiological follow-up (mean 16 months) no reappearance of symptoms was recorded.

    Notes: Abstract Discussion of the total costs and cost-effectiveness ratios of patients receiving high-dose chemotherapy (HDC) and peripheral blood stem cell support (PBSCS) is controversial. In Germany, no reliable data are available, whereas in other countries this issue has been extensively studied. We performed a pharmacoeconomic evaluation on all patients (n = 37) treated with HDC and PBSCS at our institution between July 1994 and June 1997. Patients suffered from high-risk or poor-prognosis breast cancer (n = 24), Hodgkin's disease (n = 3), high-grade non-Hodgkin's lymphoma (n = 4), multiple myeloma (n = 2), small-cell cervical cancer (n = 1), malignant hystiocytosis (n = 1) and testicular cancer (n = 2). For pharmacoeconomic evaluation, the period from initiation of induction chemotherapy (IC) until reconstitution after the last course of HDC and PBSCS was considered. A total of 18 patients received IC/HDC/PBSCS for locally advanced or systemic disease, and 19 patients received adjuvant or consolidation IC/HDC/PBSCS. Treatment protocols were heterogeneous. Patients were treated with two to five courses (median two) respectively of IC and sequential mono-HDC (n = 26), tandem-HDC (n = 10) or triple-HDC (n = 1). All patients received granulocyte/macrophage-colony-stimulating factor (G-CSF) for stem cell mobilisation and for amelioration of neutropenia after HDC. The relative costs (based on supplier prices) for the total amount of drugs prescribed during the in-patient period was 29.8% for G-CSF, 35.8% for blood products 18.5% for chemotherapy, 2.4% for antiemetics, 5.9% for antimicrobial drugs and 7.6% for other drugs. Contrary to expectations, antimicrobial drugs had only a minor pharmacoeconomic impact during IC/HDC/PBSCS in patients with high-risk or poor-prognosis malignancies, indicating that prolonged septic complications were uncommon in our institution. We conclude that pharmacoeconomic evaluations in IC/HDC/PBSCS might be integrated into the effort to ensure quality control and monitoring.
