幼儿园824名3－6岁幼儿肝功能、乙肝表面抗原检测结果分析

为了解幼儿的肝功能和ＨＢｓＡｇ携带情况，我们于１９９１年肝炎发病高峰季节对我县四所幼儿园共８２４名幼儿进行了ＡＬＴ、ＴＴＴ、ＺｎＴＴ、ＨＢｓＡｇ检测。结果ＡＬＴ、ＴＴＴ均升高１例，有体征；ＡＬＴ单项升高６例，无症状；ＨＢｓＡｇ阳性５８例，其中９例ＡＬＴ升高，４例ＴＴＴ升高。幼儿园是幼儿集中的地方、同吃、同住、接触密切，对ＨＢｓＡｇ阴性者接种乙肝疫苗，对ＡＬＴ升高者不能忽视以免发生肝炎流行。     

菏泽市城区1008名学龄儿童感觉统合失调调查分析

目的：为了解本市的学龄儿童感觉统合失调的发生率及造成感觉统合失调的有关因素。方法：采用北京感觉统合失调评定表，对6－10岁1008名在校儿童进行整群抽样调查，所获数据经χ^2检验。结果：感觉统合失调发生率为35．52％，其中轻率23．4％，重度12．1％，男童发生率为43．08％，女童发生率为27．89％，男高于女（P＜0．05）。结论：儿童感觉统合失调发生率与父母文化程度、儿童自身智力、学习成绩、出生时缺氧缺血性脑病有关，有关部门要迅速组建机构对感觉统合失调进行训练。     

农村居民艾滋病防治知识及高危行为调查研究

目的　通过对农村居民艾滋病 (AIDS)防治知识及高危行为的研究 ,为制定AIDS预防控制措施提供依据。方法　运用横断面调查研究方法 ,通过两阶段人群抽样对其AIDS防治知识及相关行为进行研究。结果　调查对象听说过AIDS的为 6 1.78% ;答对 0～ 3题为 5 6 .91% ,4～ 9题为 38.4 8% ,10～ 13题为 4 .5 5 % ;认为不可能感染艾滋病病毒的为 5 6 .94 % ,不清楚的为 38.38% ,有可能的为 4 .6 8%。 12人有卖血史 ,15人有性病史 ,在有性行为的 886人中 ,7.6 7%有过 1个以上多性伴。结论　农村居民AIDS知识匮乏 ,存在着相关危险行为。所以 ,我省预防AIDS的策略主要是开展健康教育积极推进健康促进 ,改善危险行为 ,提倡安全性行为和推广安全套的使用     

Normal morphology of sacroiliac joints in children: magnetic resonance studies related to age and sex

Objective. To determine in a prospective study the normal MRI morphology of the sacroiliac joints (SIJs) in relation to age and sex during adolescence. Design and patients. A total of 98 children (63 boys, mean age 12.7±2.8 years; 35 girls, mean age 13.7±2.3 years), ranging in age from 8 to 17 years, with juvenile chronic arthritis (JCA) but without signs of sacroiliitis fulfilled the study prerequisites (no back pain and no pathologic changes of the SIJs on physical examination before MRI in a 1.5-year follow-up). An additional eight HLA-B27-negative boys and eight HLA-B27-negative girls without arthritis served as controls. The MRI protocol comprised a T1-weighted SE sequence, an opposed-phase T2*-weighted GE sequence, and a dynamic contrast-enhanced study in single-section technique. Results. Noncontrast MRI permitted differentiation of “open” from ossified segmental and lateral apophyses of the sacral wings, with a significant difference in age (P <0.05) between children with open and ossified apophyses. Ossification of the apophyses of the sacral wings was seen significantly earlier (P <0.05) in girls than in boys. Girls also had a significantly higher incidence of transitional lumbosacral vertebrae, pelvic asymmetries, and accessory joints. In the contrast-enhanced opposed-phase MRI study, normal cartilage of the SIJs showed no contrast enhancement whereas the joint capsule showed a moderate enhancement. Conclusion. There are significant age- and sex-related differences in the normal MRI morphology of juvenile SIJs. Our findings might serve as a standard of comparison for the evaluation of pathologic changes – in particular for the early identification of juvenile sacroiliitis.     

Chronic cryptococcal meningitis in an intravenous drug addict without evidence of infection by HIV-1,2 in southern Italy

Before the emergence of AIDS, extra-pulmonary cryptococcosis was very rare. By contrast, meningeal cryptococcosis is a very common opportunistic infection in AIDS patients. We report an intravenous drug addict with cryptococcal meningitis, who was not infected with HIV and had no apparent predisposing conditions. This case, as those elsewhere described, supports the potential existence of viral agents, other than HIV-1,2, capable of encouraging the occurrence of unusual infections as have emerged during the AIDS pandemic.

三峡库区涪陵段1964至1993年肾综合征出血热的流行趋势

本文对三峡库区涪陵段1964～1993年肾综合征出血热（HFRS）的流行趋势作了某些分析，旨在兴建、开发三峡库区时为防治本病提供一定的依据。30年中发病乡（镇）的扩大与发现，以1964～1969年较为突出，占累计发病乡（镇）总数的27.59%，在嗣后的24年（1970～1993年）间仍以平均每年3.8个疫区的新发现渐进式扩大，可见三峡库区涪陵段HFRS疫区的发现与扩大仍未结束；发病率在80年代（6.58／10万）急剧上升，较60年代（3.53／10万）和70年代（2.51／10万）发病总数高1.83倍，90年代的发病率（1O.54／10万）较前26年上升57.49%；病例围绕高、中发疫区向心性集中，流行强度则离心性递减；在涪陵段的长江南岸、乌江北岸以集簇性暴发为主，长江北岸、乌江南岸为散在发病；呈5～7月（占27.03%）、10～12月（占45.79%）“双峰”型季节性发病高峰，1～4、8、9月份为非流行季节，其病例占总发病数的27.17%；每5～7年出现l次周期性发病高峰，高峰年的发病率与该地区整体发病率一致，似呈上升趋势；68.76％的病人集中在20～49岁人群，农民发病占83.35%，男女之比为2.5:1。疫区及疫源地以野鼠型为主，混合型次之，家鼠型也存在。     

Challenging the Presumption of Diminished Capacity to Parent: Does Divorce Really Change Parenting Practices?*

Abstract: The purpose of this paper is to determine whether divorced parents exhibit a diminished capacity to parent in the period following divorce. Using 2 waves of data from a national survey of Canadian children, the current study prospectively follows 5,004 children living in 2–biological parent households at initial interview and compares changes in parenting practices between households that subsequently divorce and those that remain intact. Results show that divorce is unrelated to changes in parenting behavior, suggesting that there are more similarities than differences in parenting among recently divorced and continuously married parents.
