Importance of echocardiography in prognosis of surgical outcomes in cholecystitis in elderly patients

The authors propose to use more often echocardiography (EchoCG) in examination of elderly (over 60 years) of age patients with cholecystitis that permits to increase surgical activity to 92.4%. Left ventricular ejection fraction is the most informative. When this fraction is lower than 45% surgery must be recommended on vital indications only. EchoCG was used in 155 patients with cholecystitis, 131 of them were operated. 2 (1.52%) patients died due to acute cardio-vascular insufficiency and pulmonary artery thromboembolism.

沈阳男性髋部骨折多于女性原因探讨

为找出沈阳地区髋部骨折发生男性多于女性的原因，探索该病在不发达国家或地区的流行特点，我们再次通过查阅病例记录，对沈阳市１９９４年５０岁以上人口的部分髋部骨折病发生的原因进行了较详细的调查分析。共调查分析２６６髋部骨折病例，其中男１６３例，女１０３例。损伤原因记为单纯摔倒（滑倒或绊倒）、骑自行车摔倒、自行车撞倒、机动车事故和高位跌下（滚楼梯或从较高位置掉下）。结果表明：男女在髋部骨折伤因构成上有差别（Ｐ＝０．００４）。女性髋部骨折的大多数（７０％）是由单纯摔倒引起，而在男性则不足一半（４９％），即男性髋部骨折的一半以上不是由于单纯摔倒而是由各种意外事故造成的（Ｐ＝０．０００８）。在各种意外事故中，男性骑自行车摔倒引起骨折的频率（２８％）明显高于女性（１０％）。除了骑自行车摔倒外，男性由自行车撞倒和高位跌下引起骨折的频率稍高于女性，但无太大差别。机动车事故造成骨折的频率男女基本一致。此结果在一定的程度上说明，１９９４年沈阳５０岁以上的男性髋部骨折发病率高是由于男性发生的各种意外事故多，尤其是骑自行车引起的事故造成的。
