Sharma's parachute sign a new laparoscopic sign in abdomino pelvic tuberculosis

AimsTo demonstrate a new laparoscopic sign “Sharma's Parachute sign” in abdominopelvic tuberculosis in women with infertility.MethodsA total of 104 women who were diagnosed to have abdominopelvic tuberculosis, on endometrial sampling or on laparoscopy were enrolled in this ongoing study on tuberculosis in infertility. A new laparoscopic “Sharma's parachute sign” was looked for in these cases on laparoscopy.ResultsThe mean age, pairty and duration of infertility was 27.6 years, 0.58 and 4.1 years respectively. Menstrual dysfuction were common especially hypomenorrhoea (34.61%), oligomenorrhoea (36.53%) along with constitutional symptoms and abdomino pelvic pain or lump. Diagnosis of abdominopelvic tuberculosis was made by identification of acid fast bacilli (AFB) on microscopy or culture of endometrial aspirate or peritoneal biopsy or positive gene Xpert or positive polymerase chain reaction (PCR) or histopathological demonstration of epithelioid granuloma on endometrial or peritoneal biopsy, various laparoscopic findings on pelvic and abdominal organs were tubercles and shaggy areas (white deposits, caseous nodules encysted ascites, abdominal and pelvic adhesions, tubal findings (hydrosalpinx, pyosalpinx, beaded or calcified tubes). A new “Sharma's parachute sign”in which ascending colon was totally adherent to anterior abdominal wall with its mesocolon looking like an open parachute with small caseous nodule was seen in 11 (10.5%) cases.ConclusionDiagnostic laparoscopy is an important investigation for abdominopelvic tuberculosis showing various adhesions including new parachute sign.     

The Relationship Between Air Pollution and Lung Cancer in Nonsmokers in Taiwan

Introduction

For never-smokers (smoked <100 lifetime cigarettes), lung cancer (LC) has emerged as an important issue. We aimed to investigate the effects of prevalence changes in tobacco smoking and particulate matter (PM) 2.5 (PM_2.5) levels on LC in Taiwan, in relation to contrasting PM_2.5 levels, between Northern Taiwan (NT) and Southern Taiwan (ST).

A new mouse model for the neurodevelopmental ciliopathy Joubert syndrome

Recent recognition of the key role of primary cilia in orchestrating human development and of the dire consequences of their dysfunction on human health has placed this small organelle in the spotlight. While the causal link between mutations in ciliary genes and central nervous system malformations and dysfunction is well established, the mechanisms by which primary cilia dysfunction acts on development and function of the CNS remain partly unknown. The recent article by Bashford and Subramanian in The Journal of Pathology describes a new mouse model for the neurodevelopmental ciliopathy Joubert syndrome, supporting a role for ciliary-mediated Hedgehog signaling on proliferation, survival, and differentiation of cerebellar granule cell progenitors. © 2019 Pathological Society of Great Britain and Ireland.

港九海底铁路建设中的减压病——工作条件与发病关系探讨

本文介绍香港九龙海底铁路建设中高气压作业与减压病发病情况。该工程有11条坑道,共计259 448个高压工作日,减压288 140人次,发生减压病1 534例。根据不同的工作压力,以暴露次数、高压工作日数及暴露4小时以上次数3种方法分别计算减压病发病率。结果表明:各种方法计算出的发病率都有随工作压力增高而上升的趋势,说明现用的减压表对不同的工作压力达不到同样的预防效果。本文还对3大主要工种和14个小工种的减压病作了分析。     

Turner氏综合征的临床与骨改变分析(附15例报告)

目的通过对15例有详细的临床及影像资料的Turner氏综合征分析,探讨先天性卵巢发育不良综合征(Turner)的临床与骨改变特点。方法收集15例Turner氏综合征临床及骨骼X线平片,分析其表现。结果染色体核型分3型,第1型45,X,8例;第2型46,XX,5例;第3型46,XX/45,X,2例。X线表现有:骨质稀疏14例,掌骨征阳性8例,指骨优势9例,肘外翻10例,脊柱骨化不良5例,足趾趾节短9例,颅底凹陷11例。结论Turner氏综合征患者最终身高明显低于正常人群,智力低下,性发育不全。X线表现典型,骨改变对临床的诊断具有主要参考价值。     

纯氧和空气复苏患儿24个月随访观察

目的 探讨纯氧和空气复苏对新生儿发育的影响,为新生儿复苏用氧选择提供依据.方法 对2005年1月-2007年1月在保定市妇幼保健院进行窒息复苏的30例患儿在24个月时进行随访,依据复苏用氧浓度分为纯氧复苏组(20例)和空气复苏组(10例),内容包括出生时胎龄、出生体重、身长、头围、阿氏评分(1 min,5 min)、心率(1 min,5 min)、随访时体重、身长、头围及运动发育标志(坐、爬、站、走时间).结果 出生时患儿身体数据差异无统计学意义,24个月随访,患儿身高、体重、头围及运动发育标志差异均无统计学意义(P>0.05).结论 空气复苏对新生儿窒息患者是安全有效的.
