Cheyne-Stokes breathing and systemic arterial pressure periodic pattern during sleep in central alveolar hypoventilation.

This report refers to a 51 year old man with the clinical features of central alveolar hypoventilation (CAH). Polysomnographic recordings showed periodic breathing and central apnoeas associated with abnormal oscillations of systemic arterial pressure and heart rate during all sleep stages. Oxygen administration during sleep reduced hypoxia, while the periodic breathing and arterial pressure oscillations persisted. The authors suggest that an impairment of the brain structures that play a role in homeostatic adjustment of autonomic functions in connection with the sleep-wake cycle, is responsible for the unusual sleep-related disturbances shown by this patient.

Need for multi-diagnostic approaches before considering treatment in obstructive sleep apnea.

To choose an appropriate therapeutic treatment for obstructive sleep apnea syndrome (OSAS) depends on accurately diagnosing the underlying problems that lead to the disease. Evaluating local anatomical problems is critical. New techniques, such as imaging, permit us to do this more effectively. Appreciating the involvement of the central nervous system (CNS) in a fully developed syndrome is also important. Abnormal stimulation of the autonomic nervous system can be evaluated easily with a Holter ECG. Recognizing that OSAS is a multi-faceted problem whose various symptoms interact and aggravate one another helps to explain why treatments may not be immediately effective.

Staging of heavy snorers' disease. A proposal.

The passage from trivial snoring to heavy snorer's disease or obstructive apnea syndrome is a subtle and gradual process. The suspect clinical signs of this process are primarily the onset of intermittent snoring and daytime sleepiness. We propose a diagnostic assessment based on objective monitoring of respiratory behaviour (noise of snoring, endothoracic pressure, SaO2) during sleep and the tendency to daytime drowsiness (by means of the so-called multiple sleep latency test, MSLT). These parameters establish not only the presence of a disease state, but also give a fairly accurate indication of the different stages of the disease. The nocturnal respiratory pattern emerging from this objective assessment can be divided into four stages: stage 0 (or preclinical), with sporadic obstructive apneas; stage I (or initial), with obstructive apneas persisting during light (st. 1-2) and REM sleep; stage II (or overt), with obstructive apneas persisting for the whole length of sleep; stage III (or complicated), with alveolar hypoventilation persisting during wakefulness. In stage 0, episodes of O2 desaturation are sporadically present and linked to obstructive apneas or hypopneas. In stages I-II, phasic desaturations are correlated with the apneas. In stage II and above all stage III, phasic desaturation is associated with persistent falls of Sao2.(ABSTRACT TRUNCATED AT 250 WORDS)
