Microbiology of Chronic Suppurative Otitis Media in a Tertiary Care Hospital in Bangladesh.

This cross sectional prospective study was carried out in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU) and Department of Microbiology, University of Dhaka from July 2012 to June 2013. The objectives of this study were to identify the common microorganisms involved and the antibiograms of chronic suppurative otitis media (CSOM) patients in this tertiary care hospital in Bangladesh. A total of 117 patients clinically diagnosed of CSOM were enrolled in the study. They had chronic ear discharge & had not received any topical or systemic antibiotics for the previous five days. Swabs was taken and cultured for bacteria. The standard of isolation and identification was followed. Antimicrobial susceptibility of all aerobic bacterial isolates was performed by using modified Kirby Bauer Disk diffusion method. There were 186 positive cultures for organism from 117 patients. The most common causal organisms isolated were S. aureus (47.30%) and Pseudomonas spp. (27.40%) followed by S. epidermidis (16.10%), Klebsiella spp. (8.10%) and Escherichia coli. (1.10%). Gentamicin showed the highest sensitivity (89.8%) to S. aureus whereas erythromycin showed the lowest sensitivity (14.8%) with highest resistance (67%) to S. aureus. Pseudomonas spp. showed highest sensitivity against ciprofloxacin (78.4%) and highest resistance against cloxacillin (96.1%). Novobiocin showed the highest sensitivity (100%) followed by chloram phenicol (94.1%) to S. epidermidis. Klebsiella spp. and E. coli showed highest sensitivity against chloram phenicol. This study suggests that Staphylococcus aureus and Pseudomonas are the commonest bacteria involved in CSOM in Bangladesh and Ciprofloxacin is an important tool in the management of active CSOM.

The prevalence of the arcuate artery: a cadaveric study of 72 feet.

The purpose of this study was to quantify the occurrence of the arcuate artery. The arcuate artery was defined as that artery branching off the dorsalis pedis artery at or below the level of the tarsometatarsal joint, tending laterally across the bases of metatarsals 2 through 4, and supplying dorsal metatarsal arteries 2 through 4. The arcuate artery was present in 16.7% of 72 cadaver feet that were dissected and examined, suggesting that the arcuate artery is not the primary blood supply to dorsal metatarsal arteries 2 through 4 as is commonly described. It was determined that the lateral tarsal artery supplied dorsal metatarsal arteries 2 through 4 more frequently (47.2%) than the arcuate artery. The proximal perforating arteries as well as various combinations of all three sources were also found to contribute complete blood supply to dorsal metatarsal arteries 2 through 4. Therefore, a consistent dorsal arterial network, which differentiates throughout development, better explains the blood supply of the dorsal forefoot than the arcuate artery.

Effect of heat stress on gastro-intestinal motility in young albino rats.

Motility of the gastrointestinal tract was studied by barium meal technique in control and heat exposed young and adult albino rats. As compared to the controls, the gastric emptying and the intestinal transit were significantly increased in heat exposed young rats, while in vivo intestinal absorption of D-glucose and L-proline was significantly decreased in heat exposed young rats. The rapid transit of meal through small intestine in heat exposed young rats could be responsible for decreased absorptive capacity of small intestine by reducing the exposure time for nutrients.

Role of hyperphagia in structural changes of small intestine during lactation.

The present study was conducted to investigate the cause of the structural changes of small intestine during lactation in albino rats. Anatomical measurements (total length, total wet weight and total dry weight) and histological studies of small intestine were undertaken in virgin control rats, lactating control rats, lactating rats with restricted food intake and lactating rats with restricted litter size. Restriction of food intake prevented the growth of small intestine during lactation, while restriction of litter size had no effect. Results indicate that the structural changes in small intestine are due to work hypertrophy secondary to hyperphagia and not due to any hormonal factors.

Junctures to the therapeutic goal of diabetes mellitus: Experience in a tertiary care hospital of Kolkata.

INTRODUCTION: The World Health Organization has declared India as the "diabetic capital" of the world. In controlling of such chronic, mostly asymptomatic disease, patients' role can't be overemphasized. AIMS: To assess the level of compliance to anti-diabetic therapies and to ascertain the determinants of non-compliance, if any. MATERIALS AND METHODS: A cross-sectional observational study was conducted for 3 months in a diabetic clinic of R G Kar Medical College and Hospital, Kolkata. Data were collected by interviewing the patients, examining their prescriptions and laboratory reports and anthropometry after obtaining informed consent. RESULTS: Blood report at the point of data collection revealed controlled glucose homeostasis in 38.93% patients but evaluation of past 3 months report showed only 24.3% had control over hyperglycemia. Glycemic control was seen to be positively related to short duration of disease, compliance to therapies, and high knowledge about diabetes. Compliance to therapies found in 32.22% of study subjects was in turn associated with short duration of disease. House-wives showed poor compliance; insulin treatment with or without oral-anti-diabetic agent showed better compliance. Knowledge of diabetes was significantly high among higher educated; poor among women, house-wives, and rural people. CONCLUSION: Patient-providers collaboration is to be developed through a patient-centered care model based on the mutual responsibility of both so that each patient is considered in the mesh of his/her other goals of life and helped to promote empowerment to take informed decision for behavioral change conducive to control the disease.

A study of the distribution of ABO and Rh(D) blood groups amongst Lodha tribe in Midnapore district of West Bengal.

Distribution of ABO and Rh(D) blood group was studied in 206 Lodha subjects living in the Midnapore district of West Bengal. It was observed that incidence of group A was maximum and incidence of group AB was minimum; 99.5% of the subjects were 'Rh' positive. The highest incidence of group A amongst Lodhas indicates that they might belong to the proto-Australoid group anthropologically.
