Obstructive sleep apnea syndromes.
The first description of an obstructive sleep apnea (OSA) sufferer is generally attributed to the novelist Charles Dickens, who described ‘‘Joe’’ in The Posthumous Papers of the Pickwick Club, published in 1836. Joe was an excessively sleepy, obese boy who snored loudly and had possible right-sided heart failure that led to his being called ‘‘young dropsy’’ [1,2]. The first physician to describ...
متن کاملCerebral hemodynamics in obstructive sleep apnea.
We have investigated cerebral blood flow velocity (CBVF) in 14 patients with marked obstructive sleep apnea syndrome using transcranial Doppler ultrasonography during sleep. The CBFV increased during apnea, with a mean acceleration of 0.9 cm/s2, followed by a rapid decrease during snoring. The same effect was obtained by voluntary apnea in healthy subjects, showing a smaller acceleration rate (...
متن کامل[Sleep apnea-hypopnea syndromes and heart failure].
Heart failure (HF) and sleep-disordered breathing are conditions highly prevalent in the general population that often co-exist in the same patient. Epidemiological and pathophysiological studies indicate that there may be a causal link between sleep-disordered breathing and HF with either left ventricular systolic dysfunction or preserved ejection fraction. The presence of sleep-disordered bre...
متن کاملAssessment of intracranial hemodynamics in sleep apnea syndrome.
BACKGROUND AND PURPOSE Sleep apnea syndrome may lead to changes in cerebral hemodynamics due to altered alveolar ventilation. We investigated the dynamics of CO2- and blood pressure-regulated alterations of cerebral blood flow velocities during apneic episodes and evaluated CO2 reactivity during different sleep stages. METHODS A computer-assisted pulsed Doppler system (2 MHz) was used for con...

approach which collates material that would otherwise be scattered into a variety of general, gastroenterology, and psychology journals. Journalistic editors might also have been less tolerant of the text's prosaic expressions, by no means limited to the "short lived segments of deathless prose" with which each small section is introduced. However, for this reader, far from detracting from the ...
