Disturbi respiratori del sonno e medicina del lavoro: considerazioni su tre casi clinici

Three subjects suffering from sleep-disordered breathing are described. Two of them (a 37-year-old lorry driver with obstructive sleep apnea, and a 47-year-old bricklayer with upper airway resistance syndrome) had suffered several accidents at work in few months, due to daytime sleepiness. The third patient (45-year-old) had developed (central and obstructive) sleep apnea after having been exposed to organic solvents for 15 years as a painter. In all the three subjects, polysomnography led to correct diagnosis, and nocturnal ventilotherapy with nasal CPAP (continuous positive airway pressure) considerably improved the clinical picture. The cases presented illustrate the twofold interest of sleep-disordered breathing for Occupational Medicine: on the one hand, these syndromes may reduce job performance and increase the accident risk; on the other hand, they may recognize as a risk factor the occupational exposure to solvents.
