Importance of screening the peripheral smear

A 5-year-old boy presented with history of failure to thrive from infancy. There was a history of one sibling death due to similar problems and history of severe abortions in the mother. Routine examination of peripheral smear revealed more than 50% acanthocytes. Based on this tests were streamlined to doing lipid profile and Lipo protein electrophoresis which revealed hypolipidemia and absent Β hypo protein band. Jejuna) mucosal biopsy confirmed the diagnosis of A Beta Lipo proteinemia which revealed lipid laden enterocytes. This case illustrates the importance of simple tests like peripheral smear examination in streamlining further tests in the diagnosis of major diseases.     

Quantitative study of the morphological changes in the thyroid gland following IR laser radiation

The morphological changes produced in the thyroid glands of albino rats following radiation with a 904 nm infrared laser were studied. Two different levels of radiation were applied: 46.8 J/cm² and 140.4 J/cm². Evaluation of the changes in the densities of the epithelial, colloidal and follicular volumes and of the activation index revealed that the laser beam produced changes in the thyroid parenchyma. It was observed that there was a direct relationship between the severity of the lesion and the radiation energy applied.     

Performance measures for evaluating services for people with a first episode of psychosis

Aim: The purpose of this project was to operationalize and apply a previously identified set of performance measures designed to evaluate services for those experiencing a first episode of a schizophrenia spectrum disorder. Methods: Operational definitions were developed for previously identified measures through an iterative process of discussions between clinical experts and health‐care evaluators. Data were collected from existing sources including corporate databases, clinical databases and chart review. Results: Definitions were developed for 44 measures covering seven of eight domains recommended for service level evaluation by the Canadian Institute for Health Information domains. Forty measures could be calculated. Conclusions: The measures represent a comprehensive set of performance measures suitable for the evaluation of services for people with a first‐episode psychosis. The measures could be used by other services in order to establish standards and norms for routine clinical practice.

Subclinical pulmonary oedema and intermittent haemodialysis

It has been postulated that patients with chronic renal failure,even in the absence of cardiopulmonary symptoms, accumulateinterstitial pulmonary fluid, which is removed by haemodialysis.To test this hypothesis we used the indocyanine green (ICG)-heavywater double indicator dilution method to measure lung water,cardiac output, and central blood volume in relation to haemodialysis.Ten uraemic patients, without cardiopulmonary symptoms, wereinvestigated at the beginning and end, and 2 h after, a regulardialysis session. A group of 18 surgical patients about to undergoelective abdominal surgery served as controls. Despite normalgas exchange, central blood volume, and cardiac output at thestart of dialysis the mean (SD) lung water was significantlyhigher than in the control group [4.8 (0.9) compared with 3.6(0.7) ml/kg, P<0.001]. There was no correlation between weightgain between sessions of dialysis and the magnitude of lungwater at the start of dialysis. Lung water decreased (P <0.001)to the level of the control group in response to dialysis. Therewas no correlation between weight loss and reduction in lungwater induced by dialysis. In conclusion, we have verified thepresence of subclinical pulmonary oedema which was removed bydialysis in a group of patients with established renal failure.The variations in lung water cannot be explained by hydrostaticmechanisms alone.     

2,6—二叔丁基对甲酚对大鼠尿生化指标的影响

以２０，６０和１８０ｍｇ／ｋｇ体重剂量给大鼠喂食２，６－二叔丁基对甲酚（ＢＨＴ），检测尿中ＡＳＴ、ＡＬＰ、ＬＤＨ和ＧＧＴ等指标变化。结果表明：随染毒时间延长，各尿酶含量逐渐出现显著性增高，病理学检查发现高剂量组有１例间质性肾炎，提示ＢＨＴ对肾功能可能产生有害作用。     

低温蒸汽甲醛气体灭菌效果观察

为观察低温蒸汽甲醛气体灭菌效果及其使用的可行性,采用每包内放置化学指示卡和生物指示剂,进行了实际灭菌效果检测。结果,灭菌程序记录曲线清晰,可清楚地记录灭菌日期、抽真空次数、进甲醛次数、灭菌维持时间、灭菌温度、压力、抽甲醛气体次数、空气脉冲次数和结束时间。所有包装袋外甲醛化学指示色块均由原来的橙色变为棕色;所有包内化学指示卡均由原来的深兰色变为合格的绿色。26锅次灭菌后生物指示剂全部无菌生长;对 36件灭菌后物品进行无菌检验均无细菌生长。结论,低温蒸汽甲醛灭菌效果可靠,操作简便,使用安全。     

椎动脉形态学异常对后循环短暂性脑缺血发作症状持续时间的影响

目的 探讨椎动脉形态学异常对后循环TIA症状持续时间的影响。
方法 回顾性分析2015年10月-2018年3月在中国科学院大学重庆仁济医院神经内科完成头颈部DSA
或CTA的后循环TIA住院患者临床资料，根据症状持续时间分为<10 min组、10～59 min组和≥60 mi n组，
比较椎动脉形态异常各亚型在3组间的差异。通过多因素Logistic回归分析明确椎动脉形态异常与后
循环TIA症状持续时间之间的关系。
结果 共纳入237例患者，其中症状持续时间<10 min组109例（45.99%）、10～59 min组71例（29.96%）
和≥60 min组57例（24.05%）。一般临床资料的比较显示，性别、椎动脉和基底动脉狭窄率≥50%
在3组间差异具有统计学意义（P＜0.05）。椎动脉形态异常中，动脉粥样硬化性椎动脉狭窄（狭窄
率1%～99%）在3组间的差异具有统计学意义（P =0.004），而一侧迂曲、双侧迂曲、一侧优势、一
侧优势合并迂曲和起源异常在3组间差异均无统计学意义；多因素Logi sti c回归分析显示椎动脉
狭窄（OR 2.500，95%CI 1.381～4.525，P =0.002）、基底动脉狭窄率≥50%（OR 12.066，95%CI
1.446～100.668，P =0.021）是TI A症状持续时间延长的独立影响因素。
结论 椎动脉狭窄和基底动脉狭窄率≥50%是影响后循环TIA症状持续时间延长的独立影响因素。
