Wood dusts are known to cause respiratory disorders like rhinitis and asthma. This study was therefore done to determine the magnitude of the problem among woodworkers in south-eastern Nigeria exposed to high level of wood dust. Five hundred and ninety one woodworkers were selected using a stratified random sampling. The prevalence of woodwork-related rhinitis and asthma were then observed in t...

Breast cancer tissues from 271 cases were analyzed immunologically for c-erbB-2 oncoprotein (HER-2/neu), epidermal growth factor receptor (EGF-R) and estrogen receptor (ER). Overexpression of both c-erbB-2 oncoprotein and EGF-R showed an inverse association with ER and a direct association with metastatic involvement of lymph node and high histological grade. The frequency of c-erbB-2 and EGF-R...

Our study assessed bacteria on swabs taken from the surface of the diaphragm of stethoscopes used by medical students in Nigeria. We found bacterial contamination on 80.1% of the stethoscopes. Staphylococcus aureus and Pseudomonas aeruginosa were major isolates. Bacterial colonization was highest among stethoscopes cleaned with only water and those never cleaned with any agent or never cleaned ...

BACKGROUND The baseline cardiac troponin T (cTnT) level strongly predicts short-term mortality in acute coronary syndromes, but the added value of later measures to predict short- and long-term outcome and in the context of baseline clinical characteristics is unclear. METHODS AND RESULTS Relations between baseline, peak, and 8- and 16-hour (late) cTnT results and outcomes were assessed in 73...

OBJECTIVE To estimate whether botulinum toxin type A is more effective than placebo at reducing pain and pelvic floor pressure in women with chronic pelvic pain and pelvic floor muscle spasm. METHODS This study was a double-blinded, randomized, placebo-controlled trial. All participants presented with chronic pelvic pain of more than 2 years duration and evidence of pelvic floor muscle spasm....

BACKGROUND Although high exercise tolerance is associated with an excellent prognosis, the significance of abnormal myocardial perfusion imaging (MPI) in patients with high exercise tolerance has not been established. This study retrospectively compares the utility of MPI and exercise ECG (EECG) in these patients. METHODS AND RESULTS Of 388 consecutive patients who underwent exercise MPI and ...

Virulence is the primary factor used for selection of entomopathogenic fungi (EPF) for development as biopesticides. To understand the genetic mechanisms underlying differences in virulence of fungal isolates on various arthropod pests, we compared the chitinase genes, chi2 and chi4, of 8 isolates of Metarhizium anisopliae. The clustering of the isolates showed various groups depending on their...

INTRODUCTION Eating disorders indicate unhealthy habits in nutrition and/or behaviour in the feeding and maintaining of body weight. The main characteristic of these diseases is changed behaviour in nutrition, either as an intentional restriction of food, namely extreme dieting or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misu...

PURPOSE To investigate whether single nucleotide polymorphisms (SNPs) in the OPA1 gene are associated with two primary open-angle glaucoma (POAG) subgroups: those with elevated intraocular pressure (POAG/IOP) and those with normal tension glaucoma (NTG) in the African-Caribbean population of Barbados, West Indies. METHODS SNPs at intervening sequence (IVS) 8, +4, and +32 of the OPA1 gene were...

OBJECTIVES This study has investigated the prevalence of work-related musculoskeletal disorders (WMSDs), the most commonly affected body parts, the risk factors of WMSDs and the coping strategies adopted by hairdressers. MATERIAL AND METHODS The study design was a cross-sectional descriptive survey design. Two hundred and ninety-nine hairdressers (242 females and 57 males) from salons in Suru...
