This study was conducted to assess the bacterial flora carried on stethoscopes used by medical personnel and to study the effect of disinfection of stethoscopes on the flora. In the 106 stethoscopes sampled, Gram-positive organisms were the most (60%) frequently isolated. Among them, Staphylococcus aureus accounted for 15.8% of the flora of which 21% were(More)
Primary involvement of the pancreas in bacterial and parasitic diseases is exceptional. Infection of the pancreas is usually secondary to necrosis and inflammation after serious necrotizing pancreatitis. Although a rare manifestation of a common disease, pancreatic tuberculosis can present to a clinician as a difficult diagnostic dilemma. The clinical(More)
The ability of the Vitek Yeast Biochemical Card to identify yeast isolates was compared with conventional methods. Of the fifty yeast isolates tested same species identification was obtained in thirty-four isolates. The Vitek yeast biochemical card identified 13 isolates which could not be identified by the conventional tests. Though the Vitek Yeast(More)
Pulmonary hypertension is an important cause of dyspnoea in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients. The effect highly active antiretroviral therapy on pulmonary artery pressure has been an area of controversy. The purpose of this study was to evaluate the effect of antiretroviral therapy on pulmonary(More)
Anti-mycobacterial antibody to A60 antigen were quantified in the sera and cerebrospinal fluid (csf) samples of one hundred patients of neurotuberculosis and twenty non-tubercular controls by immunoenzymatic (ELISA) assay. Sixty three patients (63%) had "significant" antibody titres in serum and/or CSF samples. In contrast, none of the samples from the(More)
A 40-year premenopausal woman was referred by her treating oncologist for F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) to rule out disease recurrence or metastasis. She had completed therapy for Hodgkin lymphoma (Stage IIA) 1 year earlier. Post-therapy gallium-67 study showed no evidence of residual disease and the(More)
Serial passage through disinfectants at sub-minimal inhibitory concentrations induced antibiotic resistances in 30.5% of the derived phenotypic variants of five strains of Staphylococcus aureus. A proportion of these phenotypic variants showed changes in their phage typing pattern by becoming susceptible to an increased number of phages, and a change from(More)
