Microbial etiology of acute gastroenteritis in hospitalized children in Taiwan.

BACKGROUND/PURPOSE: Viral infections are the most common causes of acute infectious diarrhea in the pediatric population. To explore any possible microbial etiologies of acute gastroenteritis in children, we detected stool viral antigen including rotavirus, adenovirus, norovirus and astrovirus. We also studied the possible precipitating factors. METHODS: During a period of 1 year (from October 2003 to September 2004), children from birth to 15 years old admitted to the pediatric ward were prospectively surveyed. Stool specimens were collected within 48 hours after admission and then frozen at -40 degrees C until analysis. Enzyme immunoassay was used to detect rotavirus, astrovirus, norovirus and adenovirus. Bacterial culture was performed at the same time. RESULTS: During the study period, 82 stool samples were collected due to acute gastroenteritis and fit the definition of a diarrhea episode. Forty-two (51.2%) patients with viral infection, 11 (13.4%) with bacterial infection, and six (7.3%) with mixed viral and bacterial infection were detected. The most prevalent virus was rotavirus (35.4%), followed by norovirus (29.3%). The most prevalent cause of bacterial infection was Salmonella (19.5%). With regard to clinical severity, rotavirus resulted in longer hospital stay, higher rate of vomiting, stool occult blood, leukocytosis, lower rate in stool pus cell, and C-reactive protein elevation more than 5 mg/dL as compared with norovirus. Only the difference in hospital stay reached significant statistical difference. CONCLUSION: Norovirus is an important cause of acute gastroenteritis in children, although rotavirus is still the leading cause of pediatric acute gastroenteritis.

4种黏结剂对牙本质黏结强度的比较研究

目的:比较两种第六代黏结剂-XenoⅢ、AdaperPrompt与两种第五代黏结剂-Singlebond、Singlebond2两两之间黏结强度的差异,为临床选择黏结剂提供参考依据。方法:暴露新鲜拔除的牛牙根牙本质,按照上述4种黏结剂各自的操作要求进行黏结,测试标本的微拉伸强度(μTBS)和剪切强度。结果:XenoⅢ、AdaperPrompt、Singlebond和Singlebond2的微拉伸强度(MPa)依次为:20.87±4.88,24.81±5.24,30.41±3.48,31.61±6.95;剪切强度依次为:14.85±4.26,17.23±2.57,19.18±5.65,20.92±3.73。结论:第五代黏结剂较第六代黏结剂具有更高的黏结强度,推荐使用。     

特发性甲状旁腺功能低下（附13例分析）

本文观察分析了13例特发性甲状旁腺功能低下患者、查PTH6例。患者血清中除有本病低血钙、高血磷的固有特征外，其它微量元素也有改变，如血清镁值减低。这与文献[1]的报道相符。碱性磷酸酶2例明显升高。磷廓清率S例降低。肾小管磷重吸收率5例升高。放免甲功：抗甲状腺微粒体2例升高。T细胞亚群1例低于正常值。本病有家族性，与遗传有关。

眼球挫伤与锌

从１９９１年１１月到１９９２年８月对５０例眼挫伤的血清锌进行测定，３６例异常占７２％，其中有眼底改变占７５％。视神经视网膜挫伤锌值增高。低锌影响杆细胞及锥细胞代谢致视力低下，低锌影响视色素合成及色素上皮代谢，造成伤后视网膜色紊乱。     

半乳糖-半乳糖胺检测法在大肠癌筛选中的应用

应用半乳糖-半乳糖胺检测法对118份直肠粘液标本作了检查。在30例大肠癌病人中其阳性率达90％,在65例肠粘膜正常人中,其阴性率达92.3％;另外20例大肠息肉病人中,其阳性率为15％,3例溃疡性结肠炎病人中阳性率为66.7％。结果表明:该法有较高的敏感性(90％)和特异性(92.3％),方法简便,结果易重复,在大肠癌普查中具有较大的应用潜力;在大肠息肉和溃疡结肠性炎中也有一定的阳性率,提示该法可用于某些大肠癌癌前状态恶变的监测。
