A review of incisional hernia repairs: preoperative weight loss and selective use of the mesh repair

At the Shouldice Clinic pre-operative weight loss is used prior to incisional hernia repairs. Mesh repair is selectively used, based on specific hernia characteristics. A series of 236 patients were reviewed and followed up for 36 months. Data were available on 188 patients (80%). There were 15 recurrences (8%). The number of obese patients was reduced from 67 (35.6%) to 25 (13.3%) through the weight loss program. The hernia diameter, gastrointestinal complications, and surgical site infection were significantly related to recurrence but not the type of repair, obesity, location, or previous recurrences. The risk factors of incisional hernias include size, intestinal complications and infections. A selective use has a comparable result to the exclusive use of mesh repair. Weight reduction has yet to be shown to affect the rate of recurrence, and further prospective studies are required.     

外源性NGF对坐骨神经损伤后脊髓前角细胞CNTF表达的影响

目的　探讨坐骨神经损伤后脊髓前角细胞睫状神经营养因子 (CNTF)表达变化及外源性神经生长因子(NGF)与CNTF表达的关系。方法　采用大鼠坐骨神经损伤动物模型 ,分为给药组和对照组 ,每只大鼠又分为损伤侧组 (L组 )和健侧组 (R组 )两个亚组。用原位杂交、免疫组化技术检测CNTF的表达水平 ,观察各组在 1d、7d、1 4d、2 1d及 2 8d时的变化。用计算机图像自动处理系统进行定量分析研究。结果　给药组损伤侧脊髓前角细胞中CNTF表达水平除 1d、7d组外其余均多于对照组 (P <0 .0 5 ) ;而两组健侧脊髓前角细胞中CNTF表达水平无统计学意义 (P >0 .0 5 )。结论　①外源性NGF能促进坐骨神经损伤后损伤侧脊髓前角细胞中CNTF表达水平的增加 ;而对健侧CNTF表达水平无明显作用。②坐骨神经损伤后损伤侧脊髓前角细胞中CNTF表达水平在最初的 3周内逐渐下降 ,然后开始恢复 ,但至第 4周尚未恢复到开始时的水平 ;而两组健侧CNTF表达水平则无明显差异 (P >0 .0 5 )。     

传染病流行的社会因素及社会控制策略刍议

传染病与社会文化因素的关系密切。应重视社会因素对传染病的发生发展影响，从社会根源上探究其发病原理，包括经济因素、科学技术、文化、人口、卫生服务和其它社会因素。人类要有与传染病长期斗争的思想准备，并制定包括大卫生观和技术合作等相应的社会策略。     

非霍奇金淋巴瘤85例临床及预后分析

目的：分析多种因素对非霍奇金淋巴瘤(NHL)预后的影响。方法：通过SABC法进行免疫分型，采用Kaplan—Meier法分析患者治疗后的生存期，采用Cox比例风险模型分析影响预后的因素。结果：B细胞来源-NHL(B-NHL)发病率为63．3％。T细胞来源-NHL(T—NHL)为36．7％；低度恶性占17．6％，中、高度恶性占74．1％。1、2、3、5年生存率：低度恶性患者为92．1％、84．5％、65．1％、45．1％；中、高度恶性患者为84．9％、67．5％、47．6％、28．4％。I、Ⅱ期患者为98．8％、91.5％、87．5％、70．3％；Ⅲ期、Ⅳ期患者为62．1％、55．5％、40．1％、23．8％。T—NHL为70．8％、53．5％、47．7％、30．2％；B-NHL为82．1％、70．5％、61．1％、50．1％。结论：年龄、乳酸脱氢酶水平、恶性程度、临床分期、免疫分型、身体状况评分(PS)是影响NHL预后的重要因素。     

Diabetic retinopathy: different risk factors for exudates and haemorrhages

The retinae of 137 patients were examined ophthalmologically and for visual acuity at diagnosis of noninsulin dependent diabetes and again in 1982 and 1983, approximately 7 and 8 years later, when colour photographs were also taken. In 1983, 46% were without detectable retinopathy, 32% had haemorrhages (including microaneurysms) only, 4% exudates alone and 18% both lesions. Those with haemorrhages were more hyperglycaemic than those without retinopathy and those with exudates only. Indeed, those with exudates alone had lower mean glucose levels than those without retinopathy (p<0.05). Patients with exudates (± haemorrhages) had a lower percentage of the fatty acids of plasma cholesterol esters as linoleate than those without (p<0.05) but this did not hold for those developing haemorrhages. Different risk factors appear to operate in different features of diabetic retinophathy. In some respects exudate formation may be more akin to macro than to micro angiopathy.     

Postgraduate qualifications of British doctors

Among British-qualified doctors of 1974 and 1977, about 80% held postgraduate qualifications of some kind. The commonest qualifications were DRCOG, MRCP and MRCOG. There were considerable differences between medical schools in the numbers of qualifiers taking various examinations. Apart from the MRC Psych, DRCOG and Family Planning Certificate, qualifications were more commonly held by men than women. Tables show the type of work being done 9-13 years after leaving medical school by holders of various postgraduate qualifications; e.g. 60% of MRCP holders were working in medicine or a medical specialty and 84% of FRCS holders in general surgery or a surgical specialty. Discussion deals with the plurality, specificity, variability, perceived necessity, sufficiency, international utility and career significance of British postgraduate qualifications.
