Acute pseudo-obstruction of the colon following partial splenic artery embolization: report of a case.

This is a case of a 45-year-old woman suffering from liver cirrhosis with hypersplenism who received a partial splenic artery embolization with gelfoam pieces. Thrombocytopenia and leukopenia improved immediately after treatment. Marked abdominal distention, metallic bowel sounds and combined small and large bowel distension with air-fluid levels as shown on a plain abdominal X ray were noted on the fifth day after the embolization procedure. Laparotomy was performed. No mechanical obstruction was found during surgery. Acute pseudo-obstruction of the colon (Ogilvie's syndrome) was diagnosed. This condition was considered to be a complication of the partial splenic artery embolization and has not hitherto been reported.

Bilocular atrial malignant mesenchymoma causing mitral and localized pulmonary vein flow obstruction: diagnosis by transoesophageal echocardiography.

Cardiac malignant mesenchymoma is an extremely rare malignancy with poor prognosis. We report a patient presenting with a history and clinical findings typical of mitral stenosis. Transthoracic echocardiography showed a mass on the thickened posterior mitral leaflet. Transoesophageal echocardiography revealed two tumoural masses: one on the atrial side of the posterior mitral leaflet causing mitral obstruction, the other arising in the region of the right lower pulmonary vein orifice and obstructing inflow through this vein.     

传染病研究40年（1955～1995年）

本文综述本校传染病学教研室１９５５～１９９５年间所取得的科研成果。内容包括１０余种传染病与寄生虫病的临床和基础研究，其中以华支睾吸虫病、恙虫病等有广东特色的传染病以及伤寒、痢疾、病毒性肝炎等影响人民健康最普遍的传染病为重点。反映了建国以来各个时期本教研室对防治这些传染病所作的贡献。所取得的成果，相当一部分通过多年来的验证，已获得广大传染病工作者所认同或列为常规，部分已获得部委级奖励。现在重温这些成果，可能起承前启后的意义。     

A prospective study of autologous 'blood patch' pleurodesis for persistent air leak after pulmonary resection.

OBJECTIVE: To evaluate the efficacy and risks of autologous 'blood patch' pleurodesis in patients with persistent air leak after pulmonary resection. METHODS: All patients operated on by a single surgeon between January 2002 and January 2004 and presenting with a persistent air leak after pulmonary resection have been treated by the autologous blood patch pleurodesis technique. Fifty millilitres of autologous blood were injected through the chest tube that was then rinsed, clamped for 30 min and then unclamped and placed back to water seal. RESULTS: We have obtained a 100% success rate in 11 patients with persistent air leak who have been treated with this technique over a 2-year period. Most air leaks (72.7%) ceased within 12 h of blood injection. No patient developed empyema, but two patients developed fever and pleural fluid grew Staphylococcus after blood pleurodesis. At 3-month follow-up, all patients were well and their lungs were expanded fully. CONCLUSIONS: In our experience a single injection of 50 ml of blood is sufficient to seal persistent air leaks in less than 48 h. Although highly effective, the autologous blood patch pleurodesis technique should not be used in patients with incomplete lung re-expansion or positive pleural fluid culture to minimize the risk of empyema.     

Levels of cardiovascular risk factors in type 2 diabetes mellitus are dependent on the stage of proteinuria.

Levels of cardiovascular risk factors were determined in 75 patients with Type 2 diabetes mellitus. The patients were divided into three groups according to their urinary protein excretion (UPE): (a) normal proteinuria (less than or equal to 70 mg d-1); (b) microproteinuria (70-500 mg d-1); and (c) macroproteinuria (greater than 500 mg d-1). A significant stepwise increase in mean systolic blood pressure, LDL-cholesterol and fibrinogen levels was observed from the first to the third investigated group of patients. Mean apoprotein B levels were significantly increased in the group with macroproteinuria compared to the other two groups. Significant linear correlations were found between UPE and LDL-cholesterol, total cholesterol, apoprotein B, creatinine, systolic blood pressure and diabetes duration. In summary, it is concluded that the levels of some cardiovascular risk factors increase with the stage of proteinuria in Type 2 diabetes mellitus.
