Pneumatoceles and pneumothoraces complicating staphylococcal pneumonia: treatment by synchronous independent lung ventilation.
1993
A 54 year old man with a staphylococcal sepsis developed staphylococcal pneumonia complicated by multiple pneumatoceles and bilateral tension pneumothoraces caused by bronchopleural fistulae. Excessive enlargement of the right sided pneumatoceles and a tension pneumothorax not improved by drainage led to mediastinal shift and compression of the right lung. Reversal of the mediastinal shift and closure of the bronchopleural fistulae was achieved by assisted independent lung ventilation.
Hepatozelluläre Karzinommarker bei einem primären Gallenblasenkarzinom
1987
Eine Adenokarzinomzellinie, Mz-ChA-2, konnte kurzlich aus einem primaren Gallenblasenkarzinom, das lokal in die Leber eingewachsen war, in Gewebekultur etabliert werden (1). Zyto- und Histomorphologie dieser Tumorzellinie in vitro und nach Transplantation auf Nacktmause entsprechen dem Primartumor der 65jahrigen Patientin. Im Serum wurden leicht erhohte AFP-Werte bestimmt, wahrend die CEA-Werte normal waren. Im Gewebekulturuberstand dieser neuen Tumorzellinie MZ-ChA-2 konnte AFP nachgewiesen werden. Auf klonaler Ebene zeigten sich erhebliche quantitative Schwankungen in der AFP-Synthese. CEA konnte im Gewebekulturuberstand nicht nachgewiesen werden, dem Serumbefund bei der Patientin entspre…
Biliary adenocarcinoma
1985
Three human cell lines from adenocarcinomas of the extrahepatic biliary tract were established in permanent tissue culture. Mz-ChA-1 and Mz-ChA-2 were cultured from mechanically dissociated gallbladder adenocarcinoma metastases and SK-ChA-1 was grown from malignant ascites of a patient with primary adenocarcinoma of the extrahepatic biliary tree. Cell doubling times in tissue culture are 3-4 days for Mz-ChA-1 and approximately 2 days for Mz-ChA-2 and SK-ChA-1. All three tumour cell lines were successfully transplanted to nude mice, inducing progressive tumour growth. Histologically, nude mouse tumours resembled the original adenocarcinomas. In vitro formation of gland-like structures were r…
Candida arthritis: cellular immune responses of synovial fluid and peripheral blood lymphocytes to Candida albicans.
1991
A case of septic Candida albicans arthritis of the knee in a patient with systemic candidiasis is presented. Systemic and intra-articular cellular immune responses to C albicans and various bacterial antigens were monitored for 15 weeks. It is shown that the candida induced blastogenesis of synovial fluid lymphocytes was much more stimulated than that of peripheral blood lymphocytes, and that the proportion of activated cells expressing HLA class II antigens was markedly increased in the synovial fluid. Strong cellular immune responses to Candida albicans could still be shown many weeks after the synovial fluid aspirates had become sterile. For the first time synovial fluid derived, CD4 pos…
Treatment of advanced pancreatic cancer with 5-fluorouracil, folinic acid and interferon alpha-2A: results of a phase II trial.
1995
Interferon alpha-2a (IFN-alpha) and folinic acid (FA) have been shown to modulate the cytotoxic effects of 5-fluorouracil (5-FU) in the treatment of cancer. A phase II study was initiated to evaluate the effect of a combination of 5-FU/FA/IFN-alpha in patients with advanced pancreatic cancer. Sixty previously untreated patients with advanced adenocarcinoma of the pancreas were treated with 500 mg m-2 FU via an intravenous bolus 1 h after the initiation of a 2 h infusion of 500 mg m-2 FA. Before starting the FA infusion, 6 million units (MU) of IFN-alpha was administered subcutaneously. The treatment was repeated once a week. Of 57 evaluable patients, eight (14%) had a partial response (PR),…
