ABSTRACT

In 1877, W.H. Broadbent, a British physician, provided one of the earliest

descriptions of obstructive sleep apnea syndrome (OSAS) (1) in the journal

Lancet. He characterized the condition as failure of inspiration to overcome the

resistance in the pharynx leading to snoring and periods of perfect silence during

several respiratory periods. It was not until the mid to late 1900s that the high

prevalence of this condition in children and adults was recognized by the

medical community. The mounting knowledge of OSAS and of its pathogenesis

evolved over time as we began learning about the association of the disorder

with serious adverse health outcomes. Significant progress has been made over

the last two decades in our understanding of the mechanisms mediating adverse

health outcomes due to OSAS. Such progress was supported by the technological

advances in the study of sleep, in the continuous monitoring of ventilatory

parameters, and finally in the revolution in molecular techniques. Specifically,

these advances supported the investigation of the inflammatory and metabolic

disease mechanisms in children and adults with OSAS.
