Urine sampling for HPV DNA detection has been proposed as an effective method for monitoring the impact of HPV vaccination programs; however, conflicting results have been reported. The goal of this study was to evaluate the performance of optimized urine HPV DNA testing in women aged 19 to 25 years. Optimization process included the use of first void urine, immediate mixing of urine with DNA p...
AIMS Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are sensitive and specific biomarkers for recent alcohol ingestion. This study compared urinary EtG and EtS measurement with self-reports for detection of prior drinking in alcohol-dependent outpatients treated with the anti-craving medication acamprosate or placebo. METHODS Alcohol-dependent outpatients (26 women, 30 men) were randomized t...
PURPOSE Up to 50% of urinary tract infections (UTIs) in young children are missed in primary care. Urine culture is essential for diagnosis, but urine collection is often difficult. Our aim was to derive and internally validate a 2-step clinical rule using (1) symptoms and signs to select children for urine collection; and (2) symptoms, signs, and dipstick testing to guide antibiotic treatment....
We assessed depression among 300 elderly Sudanese (age 60+ years). We conducted a cross-sectional household survey in 3 localities in Khartoum State. A 2-stage stratified sampling was carried out to select the localities and then the areas using simple random sampling; then systematic random sampling was used to select households. The prevalence of depression was 47.5%. Depression was significa...
Urine samples were collected from 152 workers (64 men, 88 women) who had been exposed to benzene, 53 workers (men only) exposed to a mixture of benzene and toluene, and 213 non-exposed controls (113 men, 100 women). The samples were analysed for 1,2,4-benzentriol (a minor metabolite of benzene) by high performance liquid chromatography. The time weighted average solvent exposure of each worker ...
Occupational exposure to tetrahydrofuran (THF) was studied by analysis of environmental air, blood, alveolar air, and urine from 58 workers in a video tape manufacturing plant. Head space gas chromatography (GC) with an FID detector was used for determination of THF concentration in alveolar air, urine, and blood. Environmental exposure to THF was measured by personal sampling with a carbon fel...
