Abdominopelvic tuberculosis simulating disseminated ovarian carcinoma with elevated CA-125 level: report of two cases.

We report the radiologic presentations of two cases of peritoneal-pelvic tuberculosis. The initial interpretation based on the adnexal masses, ascites, omental and peritoneal thickening, and elevated serum CA-125 levels led to an erroneous preliminary diagnosis of disseminated ovarian cancer. In both patients, histologic examination showed tuberculosis. The clinical and radiologic findings resolved significantly after several months of multidrug antituberculosis treatment.

Primary hepatic carcinoid tumor: dynamic CT findings.

Most carcinoid tumors involve the gastrointestinal tract or respiratory system. Primary hepatic carcinoid tumor is a rare entity. A 46-year-old woman presented with abdominal pain, vomiting, and diarrhea. She was diagnosed with primary hepatic carcinoid tumor based on radiologic and laboratory findings, namely a mass in the fifth segment of the liver and markedly elevated levels of 5-hydroxyindole acetic acid in the urine. Histologic and immunohistochemical findings of the resected liver segment showed a malignant carcinoid tumor of the liver. This case is of interest because of the rarity of this neoplasm. This report describes the case and reviews the clinical features, radiologic findings, and treatment in previously reported cases.

Reperfusion strategy after regional ischaemia: simulation of emergency revascularization and effects of integrated cardioplegia on myocardial resuscitation.

We induced ischaemia in the left anterior descending artery of 16 dogs while the heart was beating, followed by cardiopulmonary bypass (CPB), aortic cross clamping and blood cardioplegia. Half of the dogs received integrated blood cardioplegia and sudden uncontrolled reperfusion (group A) while the others received the same cardioplegia followed by pressure-controlled tepid initial reperfusion (group B). The effects on myocardial cell metabolism, oxidative stress and ultrastructure were recorded. The recovery period was significantly longer and cardiac output levels after CPB significantly lower in group A compared with group B. Group A showed a failure to uptake and utilize oxygen during the recovery period and significant lipid peroxidation. Marked tissue oedema was seen in group A but mitochondrial and organelle integrity was almost normal in both groups. We conclude that integrated cardioplegia could partially resuscitate the myocardium in this model, and pressure controlled reperfusion during the first 2 min is needed as an adjunct procedure.
