The present study evaluated the efficacy of 25 mg of quazepam, a new benzodiazepine hypnotic, in a population of chronic insomniacs. The results indicate that a single dose (25 mg) administered for one night was efficacious when measured both objectively by polysomnographic recording and subjectively by questionnaire with no reported side-effects. The change in the objective measures paralleled the direction of change in subjective measures. Sleep efficiency and sleep maintenance were improved without EEG changes in Stages 2, 3-4, and REM. Further study is needed to evaluate the effects of chronic administration of different doses of quazepam in chronic insomniacs.

Cardiovascular control was studied in infants with univentricular heart (UVH). Side motion tests and 45-s 45° head-up tilt tests were performed in 11 control and 9 UVH infants at the age of 13 ± 3.2 wk. In addition, heart rate (HR) reactions to spontaneous arousals and HR variability during slow-wave sleep (SWS) were determined. All UVH infants had been hypoxic for several weeks, and during the sleep study the mean arterial oxyhemoglobin saturation was 82 ± 5%. Tests were done at night during SWS, confirmed by polysomnographic recording. Continuous beat-to-beat blood pressure (BP) was measured. In the side-motion tests, control infants consistently showed a transient increase in HR and BP. This response was markedly reduced in all of the UVH infants ( P < 0.0001). In tilt tests, the UVH infants showed normal BP responses, but, although a sustained 2.0% decrease in HR was observed in the controls, the UVH infants presented with a sustained 2.6% mean HR increase ( P = 0.005). The UVH infants also showed attenuated HR acceleration during spontaneous arousals ( P = 0.01), but HR variability did not differ significantly from the controls. In conclusion, UVH infants with chronic hypoxia exhibit defective vestibulosympathetic pathways, as expressed by an absence of acute HR and BP reactivity to side motion. HR reactions to postural challenge and spontaneous arousal are also altered. Autonomic function abnormalities in these infants are suggested to be secondary to hypoxia.

Polysomnographic Recording

We report the first episode of Kleine-Levin (KLS) syndrome in a 17-year-old male. The illness onset, clinical features, neuropsychological evaluation and polysomnographic recording are described. Typical symptoms hypersomnia, hyperphagia and sexual disinhibition were observed besides behavioral disturbances, polysonographic and neuropsychological alterations. Behavioral disturbances similar to a manic episode including psychotic symptoms were relevant. The pharmacologic treatment included lithium, methylphenidate and risperidone. The introduction of risperidone aimed the control of psychotic symptoms and the persistent manifestations of hypersexuality after sleepness control and to the best of our knowledge there are no other report regarding risperidone use for KLS in the literature.

OBJECTIVE: Our study goal was to examine polysomnography, indices of sleep and allergy, and serum and nasal cytokines in allergic and nonallergic subjects. STUDY DESIGN AND SETTING: In this descriptive, exploratory study, 4 allergic and 4 nonallergic subjects underwent 2 nights of polysomnographic recording with serial measurements of cytokines and completed measures of sleep quality and allergic symptoms. RESULTS: Three serum cytokines (interleukin (IL)-1β, IL-4, and IL-10) were higher in allergic subjects and were termed proallergic. Three serum cytokines (IL-1ra, IL-2, and IL-12) were higher in nonallergic subjects and were termed allergy inhibitory. Proallergic serum cytokines correlated with increased latency to rapid eye movement sleep, decreased time in rapid eye movement sleep, and decreased latency to sleep onset. Low levels of allergy-inhibitory serum cytokines were associated with increased allergic symptoms. CONCLUSIONS: Differences in serum cytokines between allergic and nonallergic individuals are associated with variations in polysomnography and allergic symptoms. SIGNIFICANCE: Understanding these mechanisms may suggest novel approaches to alleviating drowsiness and other symptoms in allergic patients.
