Sixteen pregnancies were followed up in 13 patients with prosthetic heart valves: 8 pregnancies went to term under oral anticoagulation, 4 under heparin and 4 without anticoagulation. 9 healthy normal children were delivered; there were 2 still births and 5 abortions. On the maternal side 3 haemorrhages and thromboembolic episodes which involved 2 patients on heparin, one of whom died, were observed. The following points are apparent from our observations and a review of the existing medical literature: --the risk of thromboembolism is not increased. The marked clotting tendency of maternal blood post-partum contraindicates the withdrawal of anticoagulants during this critical period; --haemorrhagic complications are common with anticoagulants; --foetal loss is greatly increased; --the teratogenecity of vitamin-K antagonists is certain, but the risk is small. The problems of anticoagulation are discussed; theoretically heparin should be given during the 1st trimestre and from the 38th week to the second post-partum week. The patients should be closely supervised by both obstetrician and cardiologist and hospitalisation is advised for the last month of pregnancy. Normal vaginal delivery is usually possible. 相似文献

Cryolobulines are immunoglobulins that persist in the serum, precipitate with cold temperature and resolubilize when rewarmed. There are 3 types of cryoglobulinemia. Type II and III define mixed cryoglobulinemia. 40% approximately of patients with chronic hepatitis C virus (HCV) infection had cryoglobulinemia. OBJECTIVE: To evaluate the frequency of cryoglobulinemia in a chronic hepatitis virus (CHV) infection group and determine the characteristics of positive cryoglobulinemia patients. RESULTS: 76 patients were included. There were 53 women an 23 men. The mean age was 59.45 years. Mixed cryoglobulinemia was detected in 65 patients (85.5 %). Cirrhosis, old age and the long duration of CHV infection were the 3 factors associated with cryoglobulinemia positivity. CONCLUSION: Mixed cryoglobulinemia is a frequent manifestation during chronic hepatitis C infection virsus especially in patients with cirrhosis. 相似文献

Osler Weber Rendu Disease is an hereditary haemorrhagic télangectasia habitually revealed by reccurent bleeding (epistaxis). Hepatic involvement in Osler disease is found in 8 to 31%, manifested by cholestasis. We report an original observation of a cholangitis revealing Osler disease. 相似文献

Hydatic pulmonary embolism: complication of a cardiac hydatic cyst:a case report hydatic cardiac cyst is a rare condition and represents only 0.5 to 2% of all visceral localisations of the hydatid disease. We reported a 28 year old patient with a multiple hydatic pulmonary embolism caused by the rupture of a hydatic cyst of the interventricular septum. The diagnosis was established by transthoracic echocardiography and CT Scan. Surgery was performed without delay and the outcome was good after a five month follow-up. This case illustrates the diagnostic value of the non invasive imaging means in hydatic cyst of the heart and underlines the importance of surgery realized before complications occur. 相似文献

Cardiac involvment is rare, and intracardiac thromboses are exceptional in Behcet's disease. We present a 29 years old male patient seen for right heart-failure, thrombophlebitis and pulmonary embolism. A right atrial thrombosis was showen at the echocardiography and confirmed by computed tomography and magnetic resonance imaging. The diagnosis of Behcet's disease was established on the finding of bipolar aphtous ulcers and skin hypersensitivity. We conclude that Behcet's disease shoud be considered as a possible cause of cardiac thrombosis in the youngs men of the Mediterranean basin. 相似文献

The survey was performed during the month of March 1998 and concerned 9 ICUs located in teaching hospitals. To be included each ICU had to MV for more than 12 hours were included in the study and had a 28 day follow-up in the ICU or until hospital discharge. Collected parameters were indications of MV, modalities of MV and of weaning, complication and outcome at hospital discharge. Assist-control ventilation was the most used ventilation modality (69.8%). Weaning of MV was performed in 63% of the study patients and was based on a once-a-day attempt of spontaneous breathing through a T-piece (59.5%) and a combination of intermittent mandatory ventilation with pressure support (IMV-PS: 27%) or pressure support alone (11.2%). Mean length of hospital stay was 19.7 +/- 15.9 days of which 11.6 days were spent in the ICU. Fifty nine patients (54%) were alive at discharge form the ICU of whom 4 ultimately died during their hospital stay. MV practice as well as ICU facilities are not homogenous in Tunisia. Recommendations and guidelines should be built in order to standardize MV practice in Tunisia. 相似文献

The aim of this study is to report the results, the complications and limits of laparoscopy in patients with tuberculous peritonitis. In a retrospective study of 163 laparoscopy realized from 1970 to 1998. All the patients had exsudative ascites with predominantly of lymphocytes. Miliary nodules were found in 87% of cases, adhesions between the peritoneum and organs were found in 69% of cases and congestion in 63% of cases. Laparoscopically guide peritoneal biopsies detected caseating granulomas in 87% of cases. Laparoscopic appearance of the peritoneum mimicking a carcinosis in 15% of cases. One patient had complication as a bowel perforation. Miliary nodules and adherences are the more frequent appearances into peritoneal cavity in tuberculous peritonitis. With peritoneal biopsies, laparoscopy is always the best method for definitively and rapidly diagnosis of tuberculous peritonitis. 相似文献

In this retrospective study, 78 patients with acute biliary pancreatitis underwent endoscopic retrograde cholangio-pancreatography (31 men, 47 women; median age 61 years). It was a severe pancreatitis in 70% cases. The median time from admission to endoscopic sphincterotomy was 4 days. Endoscopic sphincterotomy was performed in 73 patients (93.3%). Bile duct clearance was achieved in 69 patients (88.37%). Overall, the complication rate was 7%. All the patients recovered after endoscopic sphincterotomy. Surgery was necessary in 40% cases. 相似文献

AIM: to investigate the effects of crude garlic on adult male rat reproductive functions. METHODS: Thirty male rats were divided into five groups: group 1 (untreated) and groups 2, 3, 4 and 5 were fed for 30 days with 5%, 10%, 15% and 30% crude garlic, respectively. Testes and accessory organs were weighed and some markers were assessed. Light and electron microscopy observations were also performed. RESULTS: A significant decrease was observed in the body weight of groups 4 (14%; P < 0.01) and 5 (20%; P < 0.01); of the prostate weight in group 5 (29.1%; P < 0.05) and of seminal vesicle weight in groups 3 (14.4%; P < 0.01), 4 (18.3%; P < 0.01) and 5 (27.3%; P < 0.01). In contrast, testis and epididymis weights were unchanged. In epididymis tissue, the alpha glucosidase activity and the spermatozoa density were unchanged. The treatment resulted in a significant decrease in testosterone serum levels in groups 3 (77.3%; P < 0.01), 4 (77.3%; P < 0.01) and 5 (90.9%; P < 0.01), associated with a significant increase in LH serum levels (P < 0.01). Testicular histology showed a dose-dependent increase in the percentage of empty seminiferous tubules. Moreover, testicular function was affected; a significant decrease in phosphatase acid activity (P < 0.01) and testosterone (P < 0.05) contents were observed. CONCLUSION: Crude garlic consumption during 1 month reduced testosterone secretion and altered spermatogenesis at 10%, 15% and 30% doses. 相似文献
