Snoring, sleep disturbance, and behaviour in 4-5 year olds.

Parents of 996 children aged 4-5 years identified consecutively from the Oxford health visitor register were asked to complete a questionnaire about breathing disorders during sleep. A total of 782 (78.5%) was returned. Ninety five (12.1%) children were reported to snore on most nights. Habitual snoring was significantly associated with daytime sleepiness, restless sleep, and hyperactivity. The questionnaire responses were used to select two subgroups, one at high risk of a sleep and breathing disorder and a control group. These children (132 in total) were monitored at home with overnight video recording and oximetry, and had formal behavioural assessment using the Conners scale. Seven (7/66) children from the high risk group and none from the control group had obvious sleep disturbance consequent on snoring and upper airway obstruction. Thus our estimate of the prevalence of sleep and breathing disorders in this age group is 7/996 or 0.7%. The high risk group had significantly higher nocturnal movement, oxygen saturation dip rates, and overnight pulse rates than the controls. Maternal but not paternal smoking was associated with the high risk group. Parents and teachers thought those in the high risk group were more hyperactive and inattentive than the controls, but only their parents thought them more aggressive. Significant sleep and breathing disorders occur in about 0.7% of 4-5 year olds. Children whose parents report snoring and sleep disturbance have objective evidence of sleep disruption and show more behaviour problems than controls.

Sleep disturbance in preschool-aged hyperactive and nonhyperactive children.

In spite of inadequate laboratory demonstrations of sleep problems in children with attention deficit disorder with hyperactivity, the belief persists that such problems exist. Sleep restlessness is, in fact, one of the criteria in the Diagnostic and Statistical Manual of Mental Disorders, ed 3, definition of attention deficit disorder with hyperactivity, and sleep problems are listed on two major checklists often used for describing the symptoms of this disorder. In a series of three studies, sleep problems were investigated in preschool-aged children with attention deficit disorder relative to control children without the disorder. Results of the first two studies demonstrated clearly that parents of hyperactive children considered their children to have many more sleep problems than did parents of the control children. Parental daily documentation, which is less likely to be affected by reporting bias, was used in the third study. Although the results of the third study supported the finding of increased frequency of night wakings in these children, there was no difference in total sleep time or sleep onset latency between the two groups. Two other significant group differences (enuresis and night sweats) were primarily due to subgroups of children with attention deficit disorder and hyperactivity. The greater number of sleep wakings, which disrupt parents' sleep, may be responsible for the clinical reports that these children are poor sleepers.

Are sleep disorders hereditary? A questionnaire survey of elderly persons about themselves and their parents.

The aim of the present study was to investigate the occurrence of sleep complaints in an elderly population in relation to the sleep pattern in their parents. The study is based on a postal questionnaire, which was sent to 10,216 elderly persons in northern Sweden. The mean (s.d.) ages of the participating men and women were 73.0 (6.0) and 72.6 (6.7) years, respectively. Among the men whose parents had no sleep problems, a good night's sleep was reported by 11.1%, and among those whose parents both had such problems, this proportion was 18.9%. The corresponding figures for women were 20.6% and 60.0%, respectively. Restless sleep, frequent awakening, difficulty in getting to sleep again after waking up in the night as well as tiredness at night but with inability to get to sleep was more common in both sexes if either of the parents had difficulty in sleeping, and even more common if such problems had occurred in both parents. Also visits to doctors because of sleep problems and treatment with sleeping pills were more common in both men and women whose parents had had sleep problems, compared with those whose parents had been good sleepers. Thus, a poor sleep was more common in elderly persons if their parents had sleep problems, compared with those whose parents had been good sleepers. The results suggest that hereditary factors could be an underestimated cause of sleep disorders in the elderly.

Wrist actigraphic measures of sleep in space.

STUDY OBJECTIVES: To determine whether wrist actigraphy is useful as a tool for space-based sleep research. Specifically, to determine whether bedtimes and waketimes can be identified from the actigraphic record, and whether actigraphic measures of sleep in space are related to polysomnographic (PSG) ones. DESIGN AND SETTING: Actigraphy, sleep diary, and Polysomnographic (PSG) measures of sleep were obtained from four subjects in two 72h measurement blocks occurring 2d and 12d into a 17d Space Shuttle mission in orbiting the earth in microgravity. PATIENTS: Four healthy male astronauts aged 38y - 47y. INTERVENTIONS: NA. MEASUREMENTS AND RESULTS: Sleep onset and offset at "night" could be quite clearly identified from the actigraphic record and were better estimated by actigraph than by diary. There was a high correlation between actigraphic and PSG estimates of sleep duration (r = 0.96) and sleep efficiency (r = 0.88), and a similarity in the mean estimates obtained. On a minute-by-minute basis, there was a good correlation between sleep stage and actigraphic movement counts, with a higher level of counts per minute recorded in epochs with lighter PSG sleep stages. There was also a high correlation (r = 0.90) between minutes of stage 0 (wake) occurring between bedtime and wake time, and number of non-zero actigraph epochs during the same interval. CONCLUSIONS: Actigraphy worked well in space both as a way of detecting bedtimes and waketimes, and as an indicant of sleep restlessness.

Circadian phase estimation of chronic insomniacs relates to their sleep characteristics.

The significance of the phase of circadian rhythmicity for the diagnosis of sleep disturbance was investigated in a group of 80 chronic insomniacs (59 females; mean age 34.8, range 18-59 years). In order to stay close to common clinical practice, data were collected by means of two-week sleep diaries in combination with repeated measurements of subjective alertness and oral temperature. Special measures were taken to minimize the impact of masking upon the temperature measurements. In addition, wrist activity was monitored for an overlapping period of 11 days. Measurements of oral temperature and subjective alertness were fitted with 3 (rd) -degree polynomials, for which the peak times (times of maximum) were identified. Principal Components Analysis of these peak times and the times of bed-in and wake-up for all subjects revealed that the phase estimates for the alertness and the sleep-wake rhythms had a strong interrelationship, which was independent from the temperature phase. Using the 25- and the 75-percentiles of the frequency distribution of the temperature peak times as boundaries, the subjects were classified into early (N = 18), middle (N = 37) and late (N = 19) temperature phase subgroups, which had mean peak times of 14:08 h, 17:43 h and 20:09 h, respectively. Comparisons between the early phase and the late phase subgroups showed that a significant overall MANOVA effect was mainly due to differences in total sleep time (early < late) as calculated from the log, and to differences in the mean nocturnal actigraphic count (early> late). Moreover, the subjective estimates of sleep latency (early < late) and wake after sleep onset (early > late) tended to differ between the two subgroups. The main result of this study, i.e., that insomniacs with a relatively advanced temperature phase had a relatively shorter and more restless sleep, while insomniacs with a relatively delayed temperature phase tended to experience a relatively long sleep latency, supports the conclusion that the addition of oral temperature measurements to a sleep/wake log extends its diagnostic and therapeutic applicability.

Sleep disturbance in children with epilepsy.

This study employed a validated pediatric sleep questionnaire to evaluate for sleep-disordered symptoms in children with epilepsy (n=14). Results were compared with those for age-matched children (n=14) with known obstructive sleep apnea. Subjects were enrolled from an outpatient epilepsy clinic and a pediatric sleep disorders clinic. We hypothesized that children with epilepsy would (1) report symptoms of sleep disturbance similar to those of children with documented obstructive sleep apnea, and (2) display behavioral disturbances on parent and child behavioral symptom measures. Results indicate that more than 50% of children with epilepsy had behavioral problems (n=14). No differences in snoring, excessive daytime sleepiness, and restless sleep were seen between the two subject groups. Results suggest that neurobehavioral problems in children with epilepsy may in part be attributed to an underlying sleep disturbance.

Sleep architecture and REM sleep measures in prepubertal children with attention deficit disorder with hyperactivity.

A 2-night polysomnographic study of 9 rigorously assessed prepubertal children who fit Diagnostic Statistical Manual-III criteria for attention deficit disorder with hyperactivity (ADDH) and a contrast group of 11 control children is reported. Despite the fact that 57% of the ADDH group were reported to experience restless sleep on structured parental rating forms, they did not show any sleep architecture abnormalities on polysomnographic recordings when compared with the normals at baseline other than decreased rapid eye movement (REM) activity. Seven of the ADDH boys were restudied after 6 months of continuous methylphenidate therapy (mean daily dose of 34.4 +/- 14.0 mg or 1.4 +/- 0.7 mg/kg). Across and within (pre-post) group comparisons showed that methylphenidate therapy was associated with delayed sleep onset, lengthened sleep, and changes in certain REM sleep variables.

Road traffic accidents in patients with obstructive sleep apnoea.

Three patients involved in road traffic accidents were suspected to have obstructive sleep apnoea (OSA). Two of them fell asleep while riding motorcycles and one patient fell asleep behind the wheel of a truck causing it to overturn. The diagnosis of OSA in each case was suspected based on a history of loud snoring, restless sleep, and excessive daytime somnolence and was confirmed by sleep studies.

[Sleep disordered breathing in group A xeroderma pigmentosum].

We studied sleep disordered breathing (SDB) in 12 patients with group A xeroderma pigmentosum (XP) by means of respiratory inductive plethysmography (Respisomnograph:Nims) during polysomnographical examination. The subjects were 6 male and 6 female patients aged from 10 months to 25 years. Four out of the subjects had SDB:3 showed sleep apnea (apnea index ranged from 5.2 to 44.2/h) and 1 presented desaturation during sleep (desaturation time per total sleep time was 4.3%). All these patients were over 12 years. The patients below 14 years had mainly the central type of SDB, and the others aged over 16 years had both the central and obstructive types of SDB. Three of the 4 patients had daytime sleepiness or restless sleep, which seemed to be due to SDB. We discussed the pathophysiology of SDB with XP in relation with brain stem function and peripheral neuropathy. We must pay attention to SDB in patients with XP aged over 12 years.

Sleep disordered breathing: effects of adenotonsillectomy on behaviour and psychological functioning.

UNLABELLED: Children on the adenotonsillectomy waiting list aged 6 years or more were screened by questionnaire and overnight sleep monitoring to identify 12 with a moderate sleep and breathing disorder (SBD) group. They were matched by age and sex with 11 children who had a similar history of snoring and sleep disturbance but without an obvious sleep and breathing problem when monitored (snorer group) and also with a group of ten children most of whom were refered for an unrelated surgical procedure (control group). All children were studied before and 3-6 months after surgery. Pre-operatively the SBD and snorer groups both had significantly more restless sleep than the control group. The SBD group also had significantly more (> 4%) dips in oxygen saturation than the other two groups. After surgery there were no longer any significant differences between the three groups. After adenotonsillectomy the SBD group showed a significant reduction in aggression, inattention and hyperactivity on the parent Conners scale, and an improvement in vigilance on the Continuous Performance Test. The snorer group also improved showing less hyperactive behaviour than pre-operatively and better vigilance. The control groups's behaviour and performance did not change significantly. There were no significant changes in the performance of the Matching Familiar Figures Test in any of the groups. CONCLUSION: Relief of mild to moderate sleep and breathing disorders in children is associated with improved behaviour and functioning. We confirm previous work which suggests that the relation between sleep disordered breathing and daytime problems in children is a causal one.

Update in obstructive sleep apnea syndrome in children.

The prevalence of OSAS in children is 0.7-3%, with peak incidence in pre-schoolers. It is characterised by partial or complete upper airway obstruction during sleep, causing intermittent hypoxia. Both anatomical (severe nasal obstruction, craniofacial anomalies, hypertrophy of the pharyngeal lymphoid tissue, laryngeal anomalies, etc.) and functional factors (neuromuscular diseases) predispose to OSAS during childhood. The main cause of OSAS in children in adenotonsillar hypertrophy. The most common clinical manifestations of OSAS are: nocturnal snoring, respiratory pauses, restless sleep and mouth breathing. Nocturnal pulse oximetry, nocturnal noise audio/videotape recording and nap polysomnography are useful tools for screening suspected cases of OSAS in children, and the gold-standard for diagnosis is overnight polysomnography in the sleep laboratory. On the contrary of SAOS adults, children usually present: less arousals associated to apnea events, more numerous apneas/hypopneas during REM sleep, and more significant oxyhemoglobin desaturation even in short apneas. The treatment of OSAS may be surgical (adenotonsillectomy, craniofacial abnormalities correction, tracheostomy) or clinical (sleep hygiene, continuous positive airway pressure--CPAP).

Diagnosis of sleep apnea.

Rapidly accumulating evidence shows that sleep apnea is a major factor influencing personal health and public safety. Diagnosis and treatment of this syndrome may well result in significant preventive medicine outcomes. The prevalence of sleep apnea is so high that evaluation and treatment must become the province of the primary care physician. Accurate, appropriate history, physical assessment and clinical management are the mainstays of care, with the judicial application of technology. A history of snoring, particularly when it is intermittent, interrupted by snorts, and accompanied by restless sleep or daytime sleepiness suggests the need for further evaluation. When co-morbid conditions such as hypertension, cardiovascular disease or type 2 diabetes are present, formal evaluation and consideration of treatment are needed. If initial evaluation reveals severe obstructive sleep apnea with observed apneas, together with excessive daytime sleepiness, clinical management with empirical application of continuous positive airway pressure (CPAP) may suffice in experienced hands.

Sleep and periodic limb movement in sleep in juvenile fibromyalgia.

OBJECTIVES: Fibromyalgia has been recently recognized in children and adolescents as juvenile fibromyalgia (JF). In adult fibromyalgia, subjective complaints of nonrestorative sleep and fatigue are supported by altered polysomnographic findings including a primary sleep disorder known as periodic limb movements in sleep (PLMS) in some subjects. Although poor sleep is a diagnostic criterion for JF, few reports in the literature have evaluated specific sleep disturbances. Our objectives were to evaluate in a controlled study the polysomnographic findings of children and adolescents with JF for alterations in sleep architecture as well as possible PLMS not previously noted in this age group. METHODS: Sixteen consecutive children and adolescents (15.0 +/- 2.6 years of age) diagnosed with JF underwent overnight polysomnography. Polysomnography was also performed on 14 controls (14.0 +/- 2.2 years of age) with no history of an underlying medical condition that could impact on sleep architecture. Respiratory variables, sleep stages, and limb movements were measured during sleep in all subjects. RESULTS: JF subjects differed significantly from controls in sleep architecture. JF subjects presented with prolonged sleep latency, shortened total sleep time, decreased sleep efficiency, and increased wakefulness during sleep. In addition, JF subjects exhibited excessive movement activity during sleep. Six of the JF subjects (38%) were noted to have an abnormally elevated PLMS index (>5/hour), indicating PLMS in these subjects. CONCLUSION: Our study demonstrated abnormalities in sleep architecture in children with JF. We also noted PLMS in a significant number of subjects. This has not been reported previously in children with this disorder. We recommend that children who are evaluated for JF undergo polysomnography including PLMS assessment. juvenile fibromyalgia; periodic limb movement in sleep; restless legs syndrome.

Sleep hygiene and migraine in children and adolescents.

Although sleep problems are a common complaint in migraine patients, the role of sleep habits and hygiene as triggering factors of head pain attacks has been poorly analyzed. The aim of this study was to evaluate the effect of modifying bad sleep habits across several headache parameters. Based on our previous study, we selected 70/164 migraineurs (42.7%) with poor sleep hygiene and randomly assigned them to two groups: group A migraineurs, who were instructed to follow directions to improve sleep hygiene; and group B migraineurs who were not given instructions on improving sleep hygiene. Mean duration and frequency of migraine attacks were significantly reduced at follow-up in group A, while group B showed only an insignificant initial reduction. No differences were found in the severity of migraine attacks that seemed related to a higher prevalence of nocturnal symptoms such as bedtime struggles, hypnic jerks, nightmares, and restless sleep. Our study is an alternative approach to the treatment of migraine, i.e. treatment through a simple modification of sleep behavior without recurring to pharmacological treatment.

Obstructive sleep apnea in the obese.

Obstructive sleep apnea (OSA) syndrome occurs in 4% to 9% of middle-aged men and in 1% to 2% of middle-aged women. The incidence of OSA among morbidly obese patients is 12- to 30-fold higher. The pathophysiology of OSA is complex and incompletely understood. The important clinical symptoms of OSA include snoring, daytime sleepiness, restless sleep, morning fatigue, and headaches. The diagnosis is made by polysomnography. The possible sequelae of OSA are hypertension, left and right ventricular hypertrophy, sudden cardiovascular death, and increased risk for brain infarction. Nasal continuous positive airway pressure (nCPAP) appears to be the recommended treatment for OSA. Morbidly obese patients may also benefit from weight reduction gastric surgery.

Psychometric evaluation of the Pittsburgh Sleep Quality Index.

The Pittsburgh Sleep Quality Index (PSQI) measures sleep quality and disturbance retrospectively over a 1-month period using self-reports. Although the PSQI has been used in a variety of populations, published psychometric data are limited. The goal of this study was to examine psychometric properties of the PSQI among four populations: bone marrow transplant patients (n=155); renal transplant patients (n=56); women with breast cancer (n=102); and women with benign breast problems (n=159). Results supported PSQI internal consistency reliability and construct validity. Cronbach's alphas were 0.80 across groups and correlations between global and component scores were moderate to high. PSQI scores were moderately to highly correlated with measures of sleep quality and sleep problems, and poorly correlated with unrelated constructs. Individuals with sleep problems, poor sleep quality, and sleep restlessness had significantly higher PSQI scores in comparison to individuals without such problems.

[Diagnosis of pediatric obstructive sleep apnea hypopnea syndrome].

OBJECTIVE: To discuss the clinical feature and diagnosis of pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) and analyze characteristics of polysomnography. METHODS: Cephalometric analysis, fibrous endoscopic examination and sleep breathing studies were performed in 49 cases with suspected complaints and signs. RESULTS: Most of them had marked history about snore, sleep apnea and signs of upper airway obstruction caused by enlargement of tonsil and/or adenoid. Polysomnography (PSG) was given to 41 cases who was proved 1 case with primary snore, 5 cases with upper airway resistance syndrome, 35 cases with OSAHS. Another 8 cases with OSAHS were diagnosed by Autoset I studies. CONCLUSION: Many features of pediatric OSAHS are different from adult OSAHS. The common symptom of pediatric OSAHS include snore, restless sleep, struggling to breathe, abnormal paradoxical chest/abdomen motion, mouth breathing, failure-to-thrive. Obesity and excessive daytime sleepiness are little present. Severe cases may be associated with cor pulmonale. PSG play an important role in exact diagnosis of pediatric sleep related breathing disorder. The results demonstrate that pediatric OSAHS are characterized by partial upper airway obstruction, more or less apnea and associated with staged desaturation. They have little sleep structure disorder and difficulty breathing are not associated with arousal. Apnea hypopnea index (AHI), lowest oxygen saturation (LSaO2) and desaturation index below 90% (SIT90%) are very important factors to measure about serious degree of pediatric OSAHS.
