Nutcracker syndrome is caused by compression of the left renal vein between the aorta and the superior mesenteric artery where it passes in the fork formed at the bifurcation of these arteries. The phenomenon results in left renal venous hypertension. The syndrome is manifested by left flank and abdominal pain, with or without unilateral haematuria. Other(More)
OBJECTIVE To investigate the extent of tobacco expenditures in Bangladesh and to compare those costs with potential investment in food and other essential items. DESIGN Review of available statistics and calculations based thereon. RESULTS Expenditure on tobacco, particularly cigarettes, represents a major burden for impoverished Bangladeshis. The(More)
One hundred sixty-five invasive Streptococcus pneumoniae strains were isolated from children under five at Dhaka Shishu (Children's) Hospital during the period 1992 to 1995. Ninety-four strains were from cerebrospinal fluid, and 71 were from blood. More than 91% of the strains were isolated from patients aged 24 months or less. Predominant serotypes were,(More)
From January 1986 through February 1993, there were 16 episodes of respiratory infection due to Corynebacterium pseudodiphtheriticum in 13 patients. The ages of patients ranged from 24 to 77 years; the ratio of male to female patients was 3:1. One patient had three episodes of infection, and another patient had two. In one patient, who died of disseminated(More)
SETTING The Chest Clinic and the JICA (Japan International Cooperation Agency) Molecular Laboratories, University Teaching Hospital, Lusaka, Zambia, and the Department of Internal Medicine, Institute of Tropical Medicine, Nagasaki University, Nagasaki, Japan. OBJECTIVE To evaluate the polymerase chain reaction (PCR) as a laboratory test for the rapid(More)
We investigated the effects of two mucoregulating drugs, S-carboxymethylcysteine (S-CMC) and N-acetylcysteine (NAC), on the attachment of Moraxella catarrhalis (M. catarrhalis) to pharyngeal epithelial cells. The attachment of M. catarrhalis decreased (33-57%) significantly (P<0.01) in a dose-dependent manner in cells treated with mucoregulating drugs as(More)
Moraxella catarrhalis is one of the major pathogens of respiratory infections and has the ability to attach to the pharyngeal cells iva fimbriae. We characterized the epithelial cell receptor to which fimbriate M. catarrhalis binds. Neuraminidase pretreatment of pharyngeal epithelial cells resulted in a significant decrease of M. catarrhalis attachment,(More)
Three hundred sixty-two Streptococcus pneumoniae strains were isolated from children under 5 years of age at Dhaka Shishu (Children) Hospital from 1993 to 1997. The strains were isolated from blood (n = 105), CSF (n = 164), ear swab (n = 61), eye swab (n = 20), and pus (n = 12). Of the 362 isolates, 42 (11.6%) showed intermediate resistance (MIC, <0.1(More)
A hospital-based prospective study of 99 patients with community-acquired pneumonia (CAP) was carried out in Kampala, Uganda. We evaluated microbiological etiologies, clinical features and effectiveness of short-term parenteral ampicillin followed by oral amoxicillin for these patients in relation to HIV-status. We demonstrated a very high prevalence (75%)(More)
Respiratory infections are initiated by the attachment of bacteria to pharyngeal epithelial cells. We studied the attachment of Burkholderia pseudomallei to pharyngeal epithelial cells. After one, two, three, and four washes, there were 22.6+/-8.9, 15.7+/-7.0, 6.8+/-3.1, and 4.6+/-1.1 (mean+/-SD) attached bacteria/cell, respectively. If the bacterial(More)
