Alterations in Pregnenolone and Testosterone Levels in Male Shift Workers.

Steroid hormone levels are closely related to the endogenous circadian rhythm induced by sleep-wake and dark-light cycles. Shift work that disrupts the circadian rhythm may influence the levels of steroid hormones. The association between shift work and alterations in female sex steroid hormone levels has been studied, but little is known about testosterone and its precursor pregnenolone levels in male shift workers.

Migraine: incorrect self-management for a disabling disease.

Migraine is an economically and socially relevant pathology but patients' consciousness and consequently a proper management is often unsatisfactory. In this study, we aimed to evaluate the disease awareness, the general approach and the impact on working activity in a population of headache-affected hospital workers. During an 18-month period, hospital workers responded to a questionnaire investigating headache presence, characteristics and awareness.
