Neighbourhood migrant composition and tobacco-related cancer mortality: A census-linked study among five origin groups in urban Belgium

We studied the role of ‘ethnic density’ in the neighbourhood for tobacco-related cancer mortality among five migrant origin groups in urban Belgium. Using full population linked census data, multilevel Poisson models were applied to model effects of three linear and categorical indicators of same-origin presence for each origin group, and to test effect mediation by migrant generation and educational level. We first of all found that increased same migrant-origin presence in the neighbourhood had protective effects on tobacco-related cancer mortality for men in most groups. Second, only Turkish men had a mortality disadvantage when Turkish concentration was higher. Third, effects were not detected across all indicators of same-origin presence, nor among most groups of women. Finally, for several groups, neighbourhood effects were mediated by generational status and educational level.     

小儿不明原因长期发热的临床诊断

目的：探讨小儿不明原因长期发热的病因及诊断方法。方法：回顾性总结分析符合FUO诊断标准的患儿76例。结果：76例中能明确诊断的72例,确诊率94．8％,未明确诊断4例（5．2％）。确诊病例中,感染性疾病42例（59％）,结缔组织病12例（16．7％）,肿瘤性疾病10例（13．8％）,其它4例（5．4％）。结论：临床只要做到详尽而确切的病史采集和必要的实验室检查,多数FUO是能明确诊断的;感染性痢疾、结 缔组织性及肿瘤性疾病是FUO的主要病因。

Infective endocarditis in paediatrics

Infective endocarditis is a result of infection of the endocardium, particularly of the heart valves (native or prosthetic valves). The most common causative organisms in the paediatric population are: Streptococci, Staphylococci and Enterococci. The classical signs of infective endocarditis like Roth spots, Janeway lesions, splinter haemorrhages and Osler's nodes are relatively rare in children. A high index of suspicion in a febrile child with a new murmur, detailed history, meticulous examination, repeated blood cultures, and echocardiography are essential in establishing the diagnosis. Management of infective endocarditis involves a prolonged course of antibiotics, at least for 4–6 weeks depending upon the causative organism and underlying heart condition. Complications of infective endocarditis include congestive heart failure resulting from valvular damage/regurgitation, infective emboli leading to abscesses in other organs and abnormal host immunological responses. Prophylactic antibiotics for dental and other medical procedures like genitourinary tract procedures are no longer recommended in the UK. The emphasis should be on educating children and their parents in early recognition of infective endocarditis. Children at high risk of developing endocarditis should be assessed urgently after clinical suspicion.     

长江中下游地区菱属植物的DNA分子鉴别

目的 对野生菱和栽培菱种rDNA ITS片段进行分析，探讨该片段在两大群体中的系统学及鉴别研究意义。方法 对菱的rDNA ITS区进行了PCR扩增、测序，运用clustal、Mega 2．0等软件对ITs区进行序列分析鉴别。结果 获得rDNAI TS1、ITS2和5．8S rDNA完整序列，10个居群菱的ITS1与ITS2序列的长度分别为234～236 bp和220～221 bp，5．8S区均为164bp，不同居群的碱基差异为0．22％～2．94％。变异位点数为16个，信息位点数6个。用NJ法根据ITS序列数据构建系统发生树。结论 尽管菱属各居群间rDNA ITS的差异百分率较小，其亲缘关系较近，但根据ITS序列的特征可以很好地鉴别野生菱、栽培菱，菱属植物有可能都起源于同一种野生类居群。     

Pseudoinfarction Pattern in an Infant

A 4-week-old female infant presented with congestive heart failure, moderate mitral regurgitation, and an electrocardiographic pattern of anterolateral myocardial infarction. Angiography revealed normal coronary arteries and moderate mitral regurgitation. A single-catheter electrophysiology study confirmed the presence of an accessory atrioventricular conduction pathway.     

葛根素注射剂与发热相关性的病例对照研究

目的：探讨不明原因短期发热（SFUO）的危险因素，论证最早上市的葛根素注射剂——普乐林与发热的相关性。方法：采取1：2匹配病例对照，选择温州医学院附属第一医院1995～1997年住院的心脑血管病病例为调查对象．将符合SFUO标准的45例纳入病例组，对照组为相匹配的90例病例。选取普乐林、其他活血化瘀中药、抗生素、生物制品、其他西药注射剂、阿司匹林服用、过敏史、微侵袭手术、重大精神刺激等9项候选危险因素，进行调查分析．筛选出危险因素。结果：单因素条件logistic回归分析将“使用普乐林”筛选为发热的危险因素，比值比（OR）为13．772．P〈0．001；多因素条件logistic回归分析显示，最终有统计学意义的只有普乐林注射液，OR值10．947。结论：最早上市的葛根素注射剂——普乐林的使用是SFUO的独立危险因素，两者存在相关性.
