A 67-year-old woman with acquired micrognathia developed severe daytime hypersomnia, loud snoring, nocturnal enuresis, encopresis, and hypertension. A polysomnogram demonstrated 564 sleep apneas, primarily obstructive, recurrent hypoxia, a bradytachycardia, and absent stages III, IV, and REM sleep. Endoscopy during sleep revealed recurrent active closure of the upper pharynx associated with loud snoring. A tracheoplasty was done because of severity of symptoms and failure of conservative therapy. Dramatic improvement in sleepiness and hypertension occurred within 48 hours. On postoperative night 15 a repeated polysomnogram showed only 23 apneas, no hypoxia or bradytachycardia, and long periods of stage II, IV, and REM sleep. Patients with the hypersomnia-sleep apnea syndrome should be provided with a tracheal opening during sleep when severe daytime somnolence, cardiac arrhythmias, and hypertension are present.

Epidemiologic studies revealed that up to 10 percent of middle-aged men show more than 10 cessations of breathing of more than 10 seconds' duration. In these patients, increased morbidity and mortality rates have been proved. More than 50 percent of apnea patients exhibit arterial hypertension, and up to 50 percent of hypertensive patients experience sleep apnea. Patients with sleep apnea and essential hypertension need special attention paid to their antihypertensive therapy because the following side effects of drugs have to be avoided: increases of cardiac insufficiency, hyperviscosity of the blood, intensification of the hypersomnia by central sedation, intensification of a pre-existing tendency towards arrhythmias, and deprivation of deep and rapid eye movement sleep. In this study, the effects of angiotensin-converting enzyme inhibitors in patients with sleep apnea and hypertension are examined. An interim evaluation of six patients (aged 50 to 57) yielded the following results: Average Broca index, 124; average blood pressure before therapy, 159/102 mm Hg; average blood pressure after therapy, 132/78; a decrease of the apnea and hypopnea index from x = 31 (range, 12 to 77) to x = 20 (range, two to 54). Therapy did not influence sleep structure: before therapy, an average of 19 percent of sleep episodes were of the rapid eye movement type (range, 11 to 32 percent); after therapy, 23 percent were of this type on average (range, 21 to 25 percent). A final evaluation will be carried out after the second study phase for 12 patients who have been treated in a double-blind scheme with metropolol versus cilazapril.

Sleep apnea and obstructive snoring are sleep related breathing disorders (SRBD). Nevertheless, there is only a quantitative difference between snoring and the obstructive form of sleep apnea. Snoring occurs in at least 20% of the population; 50% of the 50 year old male snore. Although in most of the cases only harmless snoring is concerned. It becomes serious if it leads as the independent SRBD "obstructive snoring" to a continuous oxygen desaturation and a sleep disturbance or, if in cases of sleep apnea a postapnoic snoring is concerned. The snoring pattern "loud and irregular" is always a sign for a serious SRBD. Still, no exact statement can be given concerning the frequency of obstructive snoring. However, the prevalence of sleep apnea in men of the mean age group has been determined to 10%. By the so-called sleep apnea syndrome are summarized clinical pictures with symptoms and findings caused by sleep apnea, respectively with those which can be reduced by sufficiently early introduced therapy. Most frequent symptoms and findings are: hypertension, loud and irregular snoring, daytime sleepiness and nocturnal cardiac arrhythmias. Especially hypersomnia has always to be taken seriously. In relation with other symptoms and findings associated with apnea it is always an indication for the examination for sleep apnea and obstructive snoring.

Snoring usually is trivial and unimportant, but it can turn into a social or medical problem. Obesity, hypertension and heart disease are more frequent among snorers than among nonsnorers, and especially snorers with hypersomnia during the day are at risk. Hypersomnia in association with snoring usually signifies obstructive sleep apnea. Increased resistance in the upper airways, together with negative inspiratory pharyngeal pressure and muscular hypotonia during deep non-REM and REM sleep, lead to collapse of the pharynx, hypoxia and hypercapnia. Only after arousal from sleep does muscle tone return, pharyngeal obstruction reopen and airflow resume. Since this process can occur 300 or 400 times a night, repetitive alveolar hypoventilation leads to pulmonary-arterial hypertension and cor pulmonale, and the repetitive sympathetic activations can cause systemic hypertension or serious cardiac arrhythmias. The countless arousals deprive the sufferer of deep non-REM and REM sleep and their consequence is sleep fragmentation. The symptoms are excessive daytime sleepiness, intellectual deterioration and personality and behavioral changes. Oronasomaxillofacial, endocrine and neuromuscular anomalies and diseases predispose to sleep apnea, and alcohol or CNS-depressant drugs can favour its occurrence. Diagnosis is made by nighttime oxymetry, and if this is abnormal, by polysomnography. After polysomnography it is possible to distinguish between obstructive and nonobstructive sleep apnea, and the decisions for an adequate treatment can be made.

Observations are described in 12 massively obese patients (5 women, 7 men), aged 25 to 59 years (mean 37), who weighed 312 to more than 500 pounds (mean 381). Seven patients had had systemic hypertension, 4 hypersomnia or sleep apnea, 2 diabetes mellitus, and 1 patient symptomatic coronary artery disease. Five patients died suddenly from undetermined causes, 2 from right-sided congestive heart failure, 1 patient from acute myocardial infarction; 1 from aortic dissection; 1 from intracerebral hemorrhage; 1 from a drug overdose, and 1 soon after an ileal bypass. The heart weight was increased in all 12 patients. The heart weight to body weight ratio expressed as a percent ranged from 0.22 to 0.61 (mean 0.37) (normal for men 0.42 to 0.46 [mean 0.43], normal for women 0.38 to 0.46 [mean 0.40]). The left ventricular cavity was dilated in 11 patients and the right ventricular cavity in all 12. Only 2 patients (aged 42 and 59 years) had 1 or more major epicardial coronary arteries narrowed greater than 75% in cross-sectional area by atherosclerotic plaque, 1 of whom had no symptoms of myocardial ischemia. Of 664 five-millimeter segments from the 4 major epicardial coronary arteries from 11 patients (mean 60 per patient), 431 (65%) were narrowed 0 to 25% in XSA, 143 (21%) were narrowed 26 to 50%, 73 (11%) were narrowed 51 to 75%, and 17 (3%) were narrowed 76 to 100%.(ABSTRACT TRUNCATED AT 250 WORDS)

Narcolepsy is a disabling, chronic sleep-wake disorder that typically starts in a patient's second or third decade of life. Its key features are hypersomnia and cataplexy. Sleep paralysis, hallucinations, and disrupted sleep are nonspecific symptoms and are not always present. Disability relates primarily to sleepiness- related cognitive impairment, accidents, and psychosocial problems. Treatment, which includes counseling, scheduled napping, and pharmacologic intervention, is effective for most patients. Hypersomnia is best treated with such indirect sympathomimetics as mazindol, pemoline, methylphenidate, and amphetamine. Modafinil may become the drug of choice because it has fewer side effects. Cataplexy, sleep paralysis, and hallucinations may be ameliorated by compounds, including clomipramine and imipramine, that suppress rapid eye movement (REM) sleep. Regular follow-up visits enable the clinician to recognize uncommon but serious side effects (tolerance, substance abuse, psychosis, and hypertension) and additional sleep disturbances (sleep apnea, periodic limb movements in sleep, REM sleep behavior disorder), which can be specifically treated.

The distinction between the depressive troubles according to their inclusion in bipolar disorders or in recurrent depressive disorders offers an evident practical interest. In fact, the curative and mainly the preventive treatment of these troubles are different. So it is necessary to identify the predictive factors of bipolar development in case of inaugural depressive episode. In 1983, Akiskal was the first who identified those factors: pharmacological hypomania, puerperal depression, onset at early age (<25 years), presence of psychotic characteristics, hypersomnia and psychomotor inhibition. Through this study, the authors try to compare the epidemiological, clinical and evolution characteristics of major depression in bipolar disorders to recurrent depressive disorders in order to indicate the correlated factors with bipolarity. It is a retrospective and comparative study based on about 155 inpatients for major depressive episode during the period between January 1994 and December 1998. These patients were divided into two groups according the DSM IV criteria: bipolar group (96 patients) and recurrent depressive group (59 patients). Both groups were compared according to socio-demographic data, life events in childhood, personal and family history, clinical and evolution characteristics of the index depressive episode. The predictive factors proposed by Akiskal were systematically examined. It was found out that the following factors were correlated with bipolarity: high rate of separation and divorce (17.7% versus 5.1%; p=0.02), family history of psychiatric disorders (56.3% versus 35.6%; p=0.012) especially bipolar ones (29.2% versus 3.4%; p=0,00008), onset at early age (mean age of onset: 24.8 8.2 years versus 34.1 12.6 years; p=0.000004), number of affective episode significantly more frequent (mean 3.6 versus 2.5; p=0.03), sudden onset of depressive episode (44.8% versus 15.9%; p=0.0003) and presence of psychotic characteristics (69.8% versus 16.7%; p=0.0001) catatonic characteristics (37.3% versus 20.3%; p=0.03), hypersomnia (51% versus 20.3%; p=0.03) and psychomotor inhibition (83.3% versus 42.4%; p=0.00007). Negatively correlated factors of bipolar depression were: somatic comorbidity such as diabetes, hypertension and rhumatismal diseases (12.5% versus 28.8%; p=0.012) and association with dysthymic disorders (2.2% versus 12.1%; p=0.029). No correlation was found between bipolarity and life events in childhood, seasonal character, alcoholic dependence and suicide attempt. Concerning the validity of predictive factors of bipolarity proposed by Akiskal, we found: history of bipolar disorders (Sensibility: 29.2%, specificity: 96.6%, Positive Predictive Value (PPV): 93%), hypersomnia (Sensibility: 51%, specificity: 80%, PPV: 80%), onset before the age of 25 years (Sensibility: 62.5%, specificity: 70%, PPV: 77%), psychomotor inhibition (Sensibility: 83.3%, specificity 58%, PPV: 76%), and psychotic characteristics (Sensibility: 69.8%, specificity: 62.7%, PPV: 75%). In spite of methodological differences, our results tallied with the other studies. We focus on the importance of the bipolar family history criterion, which has the highest PPV, and the limits of psychotic characteristics criterion which has the lowest PPV. This may be explained by the frequency of these characteristics of affective disorders in our cultural context. The association of the hypersomnia and psychomotor inhibition in one criterion in order to increase their diagnostic power. Our study helps us to identify the factors that would predict the bipolar evolution of a depressive episode allowing the use of specific treatment and ensuring the improvement of prognostic.

Sleep-related disorders are most prevalent in the older adult population. A high prevalence of medical and psychosocial comorbidities and the frequent use of multiple medications, rather than aging per se, are major reasons for this. A major concern, often underappreciated and underaddressed by clinicians, is the strong bidirectional relationship between sleep disorders and serious medical problems in older adults. Hypertension, depression, cardiovascular disease, and cerebrovascular disease are examples of diseases that are more likely to develop in individuals with sleep disorders. Conversely, individuals with any of these diseases are at a higher risk of developing sleep disorders. The goals of this article are to help guide clinicians in their general understanding of sleep problems in older persons, examine specific sleep disorders that occur in older persons, and suggest evidence- and expert-based recommendations for the assessment and treatment of sleep disorders in older persons. No such recommendations are available to help clinicians in their daily patient care practices. The four sections in the beginning of the article are titled, Background and Significance, General Review of Sleep, Recommendations Development, and General Approach to Detecting Sleep Disorders in an Ambulatory Setting. These are followed by overviews of specific sleep disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Circadian Rhythm Sleep Disorders, Parasomnias, Hypersomnias, and Sleep Disorders in Long-Term Care Settings. Evidence- and expert- based recommendations, developed by a group of sleep and clinical experts, are presented after each sleep disorder.
