Routinely collected general practice data aids identification of people with hyperglycaemia and metabolic syndrome.

AIMS: To assess the performance of a risk score comprising data routinely available in general practice records (age, gender, body mass index, family history of diabetes, smoking habits and prescribed anti-hypertensive drugs or steroids) in detecting diabetes, impaired glucose tolerance and metabolic syndrome. METHODS: In a population-based, cross-sectional study in a semi-rural general practice in Jutland, Denmark, Cambridge Risk Scores were calculated for 1355 patients without known diabetes (69% response rate) who completed questionnaires and underwent anthropometric measurement and an oral glucose tolerance test. RESULTS: Prevalences of diabetes, impaired glucose tolerance and metabolic syndrome were 2.29% (95% CI: 1.56-3.23), 6.64% (95% CI: 5.38-8.10) and 13.4% (95% CI: 11.5-15.2), respectively. Area under the ROC curve for the risk score and diabetes was 83.8% (75.9-91.7) and for metabolic syndrome [European Group for the Study of Insulin Resistance (EGIR)] was 78.1% (74.6-81.6). Twenty per cent of the population had a risk score above 0.246; at this threshold the sensitivity to detect diabetes was 71.0% (53.4-83.9), the specificity 81.2% (79.0-83.2), positive predictive value 8.1% (6.6-10.0) and likelihood ratio 3.77 (2.94-4.85). For metabolic syndrome (EGIR) corresponding values for sensitivity were 50.3% (43.1-57.5), specificity 84.7% (82.5-85.6), positive predictive value 33.6% (28.2-39.4), and likelihood ratio 3.28 (2.69-4.00). CONCLUSIONS: Undiagnosed hyperglycaemia and metabolic syndrome are common. The Cambridge Risk Score is a practical first step in a screening procedure to identify individuals with these disorders who might benefit from diagnostic testing or to direct preventive interventions.     

扶正调平汤减轻化疗毒副反应的临床观察

目的研究在化疗过程中运用扶正调平汤对减轻肿瘤患者的骨髓抑制，消化道症状等化疗副反应的作用。方法通过临床对60例手术及非手术胃癌患者随机分成两组，即治疗组和对照组，观察化疗前后两组的血象变化、消化道反应情况，及其生活质量进行评定，比较、分析。结果实验证明化疗同时配合扶正调平汤对改善化疗副反应的作用显著化于对照组（P〈0．05）。结论说明扶正调平汤对减轻化疗毒副反应方面具有较好的临床疗效。提高了患者生活质量，使惠者顺利完成化疗疗程。     

Comparison of propofol induction with thiopentone or methohexitone in short outpatient general anaesthesia

The per- and post-operative characteristics of three different i.v. anaesthetic induction agents were studied double-blindly in 75 patients admitted for outpatient gynaecological dilatation and curettage. All the patients were premedicated with midazolam 0.1 mg/kg i.m. Induction started with alfentanil 0.015 mg/kg i.v. 60 s before either: propofol 2.2 mg/kg i.v., or thiopentone 4.0 mg/kg i.v., or methohexitone 2.0 mg/kg i.v. All the patients received 66% nitrous oxide in oxygen. The propofol patients were significantly better relaxed and had a higher incidence of hypotension during the procedure. The methohexitone patients had higher pulse rates and a higher frequency of hiccups during the procedure. Propofol induction resulted in a faster awakening of the patients and a better recovery function compared with methohexitone for the first 15 min and compared with thiopentone for the first 240 min after the procedure. Postoperative side-effects were less frequent in the thiopentone group, and minor abdominal pain was significantly more frequent in the propofol group. There was no significant difference between the groups for any variable after 240 min postoperatively.     

第二足趾跖侧菱形皮瓣转移改形法再造拇指

目的介绍第二足趾跖侧菱形皮瓣转移改形再造拇指的方法。方法用传统方法切取第二足趾后,于第二足趾近段跖侧设计菱形皮瓣,用180°逆形转移或向远侧直接推进的方法将皮瓣嵌入第二足趾跖侧狭细处,以改善其外形。结果临床应用6例,再造拇指全部存活。术后随访3～24个月,再造拇指外形美观,感觉运动恢复满意。结论用第二足趾跖侧菱形皮瓣转移改形法再造拇指,能明显改善第二足趾的外形,使再造拇指更美观。

Polymorphism analysis of four canine MHC class I genes

Abstract: We have studied the variability of four structurally complete dog leukocyte antigen (DLA) class I genes, termed DLA-12, -88, -79 and -64, in a population of mixed breed, unrelated dogs. The human HLA and canine DLA loci share a high degree of similarity in terms of gene structure. This analysis focused on the first three exons of each of four complete canine genes. Exons two and three are the major source of polymorphism in the corresponding human genes. In this analysis, DLA-88 was found to be significantly more polymorphic than the other three genes, with 44 distinct alleles observed among 63 mixed breed, unrelated dogs. The remaining genes had between one and four alleles when examined in 25 dogs. This work was carried out as part of an effort to develop an MHC typing system for the dog, which is critical to the further development of preclinical studies of hematopoietic stem cell and solid organ transplantation in the canine model.     

Social class and obesity in 12-year-old children in Brussels: Influence of gender and ethnic origin

From their school health files, the body mass index of 2607 children, 1268 boys and 1339 girls, from the Brussels region of Belgium was analysed. The aim was to study the relationship between obesity and social class, gender and nationality. In Belgian girls, the lower their social class, the higher was the prevalence and severity of obesity. There was no such significant relationship in Belgian boys, nor in immigrant children of either sex, although the overall prevalence of obesity was similar in all groups. These results question certain hypotheses proposed to explain the relationship between social class and obesity. Conclusion From early adolescence on, social inequality influences the prevalence of obesity in Belgian girls, but not in Belgian boys nor in immigrant children. Prevention of obesity should take into account the influence of gender, social class and ethnic origin. Received: 21 January 1997 and in revised form: 30 September 1997 / Accepted: 21 October 1997
