A health survey was conducted on 199 workers engaged in dividing and packaging pyrethroids. The subjects were exposed to fenvalerate at 0.012-0.055 mg/m3 and deltamethrin at 0.005-0.012 mg/m3 in the air with simultaneous skin contact for 0.5-4.5 months. Burning sensations and tightness or numbness on the face appeared in two thirds of the subjects and one third had sniffs and sneezes. Abnormal facial sensations, dizziness, fatigue, and miliary red papules on the skin were more evident in summer than in winter. Neither abnormalities in other organs or systems nor symptoms or signs of acute pyrethroid poisoning were found by interviews, examinations, and laboratory tests. There was no significant difference in plasma levels of NA, cAMP, and cGMP between the examined subjects and the control group. The urine concentration of fenvalerate in the study group ranged from 1.02 to 18.6 micrograms/l; deltamethrin in the urine was present in trace amounts.

Data from 5 studies recently conducted in Bangladesh regarding dizziness as a major side effect of oral contraceptive (OC) use were reviewed. The Bangladeshi women describe dizziness as "Mata gurai" (headspinning), a sensation of rotary motion unaccompanied by nausea or vomiting. It appears to mimic the characteristics of postural hypotension rather than true vertigo and is often associated with generalized weakness. Both dizziness and weakness were cited by a large proportion of women in study A as reasons for discontinuation, and the 2 symptoms were often linked. Burning sensations, usually in the extremities, also proved to be a frequent cause of discontinuation. In study B, except for dizziness, there was no significant difference between women continuing OC use and those who had stopped use. The incidence of dizziness reported by discontinuers was significantly higher than that reported by continuing users. The case-control health survey used in study C corroborated the view that some complaints associated with OC use were equally common in nonusers, but the incidence of dizziness and eye problems was significantly higher in OC users than in both matched control groups. There were no significant associations found between dizziness and hemoglobin levels or blood pressure in study D. Of those women who took multiple vitamin capsules in study E, 57% reported a lessening of dizzinesss, compared with 69% who received glucose capsules.
