STUDY OBJECTIVES To assess the efficacy of continuous positive airway pressure (CPAP) in obstructive sleep apnea (OSA) patients who are < 2 years of age. DESIGN A retrospective chart review of 18 patients from 1992 to 1999 who had OSA confirmed by polysomnography. All patients in this study also completed a separate night of CPAP polysomnography to determine the effectiveness of CPAP in the c...

OBJECTIVE To determine clinical and baseline polysomnographic data on obstructive sleep apnoea secondary to adenotonsillar hypertrophy in Hong Kong Chinese children. DESIGN Prospective study. SETTING University teaching hospital, Hong Kong. PARTICIPANTS Fifty children (35 boys and 15 girls) suspected to have obstructive sleep apnoea were recruited between January 1999 and December 1999. ...

Cardiac vagal control (CVC) has been linked to both physical and mental health. One critical aspect of health, that has not received much attention, is sleep. We hypothesized that adults with higher CVC--operationalized by high-frequency heart rate variability (HF-HRV)--will exhibit better sleep quality assessed both subjectively (i.e., with Pittsburgh Sleep Quality Index) and objectively (i.e....

Treatment options may be limited for infants with obstructive sleep apnea when there is no surgically correctable upper airway lesion. We therefore evaluated, retrospectively, the efficacy of low-flow oxygen as a therapeutic option for infant obstructive sleep apnea. We reviewed the medical charts of 23 infants who had undergone a therapeutic trial of low-flow oxygen during polysomnography. Spl...

background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...

BACKGROUND The initial experience with continuous positive airway pressure (CPAP) may predict subsequent compliance. In a retrospective study, we found that premedication with nonbenzodiazepine sedative-hypnotic agents during CPAP titration polysomnography independently predicted short-term compliance. To validate these findings, we conducted a prospective clinical trial to assess whether preme...

PURPOSE To evaluate sleep disturbances or sleep related events and their characteristics among patients with medically refractory epilepsy, compared to those with controlled epilepsy. METHODS In a prospective case-controlled study, patients of medically refractory and controlled epilepsy were recruited and history pertaining to epilepsy and sleep related events and Epworth sleepiness scores w...

OBJECTIVE To investigate the impact of obstructive sleep apnea syndrome (OSAS) on night-time secretion of brain natriuretic peptide (BNP) and antidiuretic hormone (ADH) in older men with nocturia accompanied by nocturnal polyuria. MATERIALS AND METHODS One hundred six men with nocturia aged ≥ 60 years underwent full-night polysomnography to determine whether they had OSAS. Blood count, standa...

Objectives. To identify whether sleep disturbances are more prevalent in primary SS (pSS) patients compared with the general population and to recognize which specific sleep symptoms are particularly problematic in this population. Methods. Electronic searches of the literature were conducted in PubMed, Medline (Ovid), Embase (Ovid), PsychINFO (Ovid) and Web of Science and the search strategy...

OBJECTIVE The purpose of the study was to evaluate quantitative sleep electroencephalogram (EEG) frequencies in monozygotic twins discordant for chronic fatigue syndrome. METHODS Thirteen pairs of female twins underwent polysomnography. During the first night, they adapted to the sleep laboratory, and during the second night, their baseline sleep was assessed. Visual stage scoring was conduct...
