Low HDL‐cholesterol is common in European Type 2 diabetic patients receiving treatment for dyslipidaemia: data from a pan‐European survey

Aims To measure the prevalence of low high‐density lipoprotein (HDL)‐cholesterol (men < 1.03 mmol/l; women < 1.29 mmol/l) in European Type 2 diabetic patients receiving treatment for dyslipidaemia. Methods The pan‐European Survey of HDL‐cholesterol measured lipids and other cardiovascular risk factors in 3866 patients with Type 2 diabetes and 4436 non‐diabetic patients undergoing treatment for dyslipidaemia in 11 European countries. Results Diabetic patients were more likely to be obese or hypertensive than non‐diabetic patients. Most patients received lifestyle interventions (87%) and/or a statin (89%); treatment patterns were similar between groups. Diabetic patients had [means (SD)] lower HDL‐cholesterol [1.22 (0.37) vs. 1.35 mmol/l (0.44) vs. non‐diabetic patients, P < 0.001] and higher triglycerides [2.32 (2.10) vs. 1.85 mmol/l (1.60), P < 0.001]. More diabetic vs. non‐diabetic patients had low HDL‐cholesterol (45% vs. 30%), high triglycerides (≥ 1.7 mmol/l; 57% vs. 42%) or both (32% vs. 19%). HDL‐cholesterol < 0.9 mmol/l was observed in 18% of diabetic and 12% of non‐diabetic subjects. Differences between diabetic and non‐diabetic groups were slightly greater for women. LDL‐ and total cholesterol were lower in the diabetic group [3.02 (1.05) vs. 3.30 mmol/l (1.14) and 5.12 (1.32) vs. 5.38 mmol/l (1.34), respectively, P < 0.001 for each]. Conclusions Low HDL‐cholesterol is common in diabetes: one in two diabetic women has low HDL‐cholesterol and one diabetic man in four has very low HDL‐cholesterol. Management strategies should include correction of low HDL‐cholesterol to optimize cardiovascular risk in diabetes.     

Influence of tumours on normal cells and optimal chemotherapy regimens: the case of several drugs and toxicity constraints.

Cancer chemotherapy with the application of several drugs is studied. The negative and inhibiting effect of the tumour on normal cells is taken into account. Under certain hypotheses, we determine the optimal regimen that minimizes the tumour burden at the end of a fixed period of therapy while maintaining several normal cell populations above prescribed levels. More precisely, it is demonstrated that the optimal drug administration corresponds to the strategy of intensive chemotherapy.     

Aspiration biopsy cytology of mammary myoepithelioma

A case of ultrastructurally confirmed myoepithelioma of the breast studied by fine-needle aspiration biopsy is reported. Aspirated tumor cells were spindle-shaped with well-defined cytoplasm and oval nuclei showing no remarkable nuclear pleomorphism. They were seen mainly in irregular bundles with strong cellular cohesiveness. Their cytoplasm contained S-100 protein demonstrated by the peroxidase antiperoxidase staining technique.     

Undergraduate psychiatry teaching in Ethiopia

Many epidemiological studies have shown the magnitude and seriousness of mental disorders in developing countries. However, mental health care remains unsatisfactory owing to lack of skilled manpower and many other social and medical priorities. General practitioners and other health personnel can significantly help in extending mental health care provided they receive adequate training during their medical curriculum. With this aim, the Department of Psychiatry at Addis Ababa University runs a 6-week full-time course for undergraduate medical students. Its chief objectives, teaching methods, achievements and shortcomings are discussed in the paper.     

腹股沟浅淋巴结移植的应用解剖

本文在32侧成人尸体上,对腹股沟浅淋巴结的形态及血供进行了观察和测量。腹股沟部上外区淋巴结有恒定的旋髂浅血管供应。动脉外径平均约1.5mm,干长21.8mm,营养2～6个淋巴结、该区是吻合血管移植淋巴结的首选供区。     

老年人急性阑尾炎的腹腔镜手术治疗

目的 探讨老年人急性阑尾炎的临床特点，更好地把握腹腔镜阑尾切除（LA）术的方法和特点。方法 回顾分析50例老年人急性阑尾炎LA的临床资料。结果 LA均获成功，患者全部治愈，无严重的并发症发生，肠功能恢复时间及住院时间均缩短。结论 老年人反应迟钝，阑尾炎进展快，易发生坏疽及穿孔，合并症多，手术风险较高，LA是安全、可行的，除个别腹膜后阑尾炎外，其余均可施行LA。     

胎膜早破并发胎盘早剥的临床分析

目的　探讨妊娠晚期胎膜早破并发胎盘早剥的发生率、早期诊断和处理要点。方法　回顾分析2 0 0 1年～2 0 0 4年郑州大学第三附属医院产科分娩的胎膜早破病例,其中并发胎盘早期剥离者8例,与非胎膜早破发生胎盘早剥者进行比较。分析早期诊断和母婴结局。结果　3年分娩总数为4 12 4例,胎膜早破并发胎盘早剥者占全部胎盘早剥的2 8 6 % ,胎膜早破是胎盘早剥的首位发病诱因。胎膜早破并发胎盘早剥的发生率为2 77% ,而非胎膜早破者为0 5 2 % ,两者相比差异有显著性(P <0 0 1)。间断腰痛、血性羊水、胎心异常为常见的临床表现。胎膜早破并发胎盘早剥时围产儿的死亡率为12 5‰,无孕产妇死亡。结论　胎膜早破是胎盘早剥的诱因之一,重视临床表现,并结合B超和胎心监护有助于早期诊断,以降低母儿并发症。     

Circulating adipocytokines in non-diabetic and Type 1 diabetic children: relationship to insulin therapy, glycaemic control and pubertal development.

AIM: To determine the influence of Type 1 diabetes mellitus on circulating adipocytokines in children. METHODS: The circulating concentrations of leptin, adiponectin, resistin and tumour necrosis factor (TNF)-alpha were measured in 91 children, aged 11.1 +/- 2.7 years, with Type 1 diabetes mellitus (T1DM). Ninety-one healthy children were selected as control subjects. RESULTS: Body mass index-adjusted leptin concentrations were higher in the pubertal diabetic children compared with the control children. There was a significant positive correlation between leptin and daily insulin dose in the diabetic group. Circulating adiponectin concentrations were higher in the prepubertal diabetic children and were positively associated with HbA(1c). Resistin concentrations were lower in the prepubertal non-diabetic subjects compared with the pubertal non-diabetic children, whose values were higher than those of the diabetic children. TNF-alpha concentrations were similar in non-diabetic and diabetic children. CONCLUSIONS: Circulating concentrations of adipocytokines are abnormal in Type 1 diabetic children, although the direction of change differs by cytokine. Pubertal development, in addition to insulin treatment and glycaemic control, also influences the concentrations.
