Oxidative stress, melatonin level, and sleep insufficiency among electronic equipment repairers.

Background: Exposure to extremely low frequency electromagnetic field (ELF-EMF), especially among electronic equipment repairers may induce oxidative stress and affect sleep quality.

Aims: This study was carried out to (a) investigate the effect of exposure to ELF-EMF on the malondialdehyde (MDA) levels among electronic equipment repairers as an indicator of oxidative stress; and melatonin hormone levels; and (b) to study the prevalence of sleep insufficiency among electronic equipment repairers exposed to ELF-EMF.

Materials And Methods: A cross-sectional study was carried out on 50 electronic equipment repairers at high risk of exposure to ELF-EMF, and a matched control group at lower risk of exposure to ELF-EMF.

Can a single serum CA125 assay predict the outcome of threatened abortion?

Earlier work suggested that high levels of CA125 could be detected in the sera of women with threatened abortion. In this study, we used CA125 as a method of anticipating outcome in cases of threatened abortion and compared the results with ultrasonic findings. Three groups of patients were studied.

Pretreatment cystatin C in children with malignancy: can it predict chemotherapy-induced glomerular filtration rate reduction during the induction phase?

Background: Monitoring of kidney function is essential during chemotherapy. Serum creatinine is of limited value in early detection of renal insufficiency. The cystatin C level has been proved to be a good marker for detection of mild reduction in glomerular filtration rate.
