A Study of Upper GI Endoscopic Findings in Patients Presented with Upper GI Bleed.

INTRODUCTION: Bleeding from upper gastrointestinal tract is approximately five times more common than bleeding from lower gastrointestinal tract. The most common cause has been gastroduodenal ulcer disease, Esophageal varices, Mallory-Weiss tear. MATERIALS: It is an observational study carried out in General medicine department in GSL hospital in patients presented with history of vomiting of frank blood and/or passed dark coloured stools were chosen for this study with an aim to find out the prevalence of nature of lesion on Upper Gastro Endoscopy in patients admitted for UGI bleed and to find out the prevalence of nature of lesion. RESULT: Detailed history regarding the UGI bleeding like number of times of hematemesis approximate quantity of blood vomited each time, associated with malena. Symptoms of common diseases that can lead to UGI bleeding and detailed history of drug intake like aspirin, other NSAIDs, steroids and symptoms due to blood loss were recorded in the questionnaire. CONCLUSION: The peptic ulcer disease was the most common lesion found on endoscopy with prevalence of 54% and Varices with prevalence of 16% Minor UGI bleed was the commonest presentation. Majority of lesions (60%) presented with minor UGI bleed 28% lesions presented as moderate UGI bleed. Only 8% presented as major UGI bleed. Varices account for the most common cause for major UGI bleed contributing 50%. Gastric ulcer was commonest lesions accounting for 37 cases (37%) among 72 cases having single acid peptic lesions on endoscopy. The second most common is common is duodenal ulcer (31%).

A rare case of Turner's syndrome presenting with Mullerian agenesis.

Turner's syndrome also called as Ullrich Turner's syndrome, is a disease of unclear pathogenesis characterized by complete or partial absence of one sex chromosome, with or without cell line mosaicism in a phenotypic female with short stature. Various anomalies result in a constellation of features, of which the most disturbing is primary amenorrhea due to gonadal dysgenesis. Hormone therapy in these patients can often result in successful menstruation, and scope for subsequent pregnancy because of anatomically normal uterus and vagina. Coexisting Mullerian agenesis in these patients can jeopardize the chances of future pregnancy as they have associated structural abnormalities of the uterus and vagina. We report a rare case of middle-aged female with Turner's syndrome and Mullerian agenesis having absent secondary sexual characters and missing uterus with incompletely formed vagina.

Enhanced microfiltration devices configured with hydrodynamic trapping and a rain drop bypass filtering architecture for microbial cells detection.

Ultra-fine (<1 microm) microfilters are required to effectively trap microbial cells. We designed microfilters featuring a rain drop bypass architecture, which significantly reduces the likelihood of clogging at the cost of limited cell loss. The new rain drop bypass architecture configuration has a substantially lower pressure drop and allows a better efficiency in trapping protozoan cells (Cryptosporidium parvum and Giardia lamblia) in comparison to our previous generation of a microfilter device. A modified version displaying sub-micron filter gaps was adapted to trap and detect bacterial cells (Escherichia coli), through a method of cells labeling, which aims to amplify the fluorescence signal emission and therefore the sensitivity of detection.
