The aim of this randomized controlled trial was to assess the effects of treatment with continuous positive airway pressure versus conservative therapy (CT) on well-being, mood, and functional status in subjects with mild sleep-disordered breathing (SDB). One hundred and eleven subjects, aged 25 to 65 yr, with a respiratory disturbance index (RDI) of 5 to 30 and without subjective pathologic sleepiness, were randomized to nasal CPAP or to CT. Ninety-seven subjects were followed-up after 8 wk. Treatment response was assessed from changes between baseline and follow-up measures of mood, energy/fatigue, and functional status/general health. Of the 51 subjects randomized to CPAP, 25 (49%) experienced an improved outcome, as compared with 12 of 46 of subjects (26%) randomized to CT (p < 0.05). The odds of experiencing a treatment response in the CPAP as compared with the CT group were 2.72 (OR: 1.18 to 6.58, 95% CI). A beneficial effect of CPAP over CT was most evident among individuals without sinus problems and among subjects with hypertension or diabetes. Differential treatment responses were not related to degree of baseline sleepiness or SDB. This suggests that middle-aged snorers with relatively low levels of SDB (RDI < 30) may benefit more from nasal CPAP than from less specific therapy directed at improving breathing during sleep. CPAP therapy may be beneficial to a broader group of subjects than previously appreciated.

A 64-year-old man with multiple system atrophy complained of daytime sleepiness, fatigue, and snoring. Neurological examination revealed severe autonomic failure, mild cerebellar ataxia and akinesia. Daytime blood gas analysis showed respiratory acidosis with hypoxia and hypercapnia. MR imaging of the brain showed atrophy of the pons, cerebellum and bilateral frontal lobes. Although paralysis of the vocal cord abduction was not found by laryngoscopy during daytime examination, polysomnography (PSG) showed heavy snoring with paradoxical respiration associated with severe desaturation during sleep as well as reduced slow wave sleep and REM sleep. He was diagnosed as having sleep-related upper airway obstructive breathing disorder probably due to Gerhardt syndrome. Tracheostomy was considered, but we performed nasal CPAP therapy during sleep because this therapy is non-invasive and would not impair his daily life. After nasal CPAP therapy, daytime sleepiness, fatigue, and snoring with desaturation improved, and PSG showed increased slow wave sleep. These results demonstrate that nasal CPAP therapy improves the quality of sleep and should be considered in patients with early stages of multiple system atrophy who exhibit sleep-related breathing disorders.

This study compared sleep architecture in women and men with sleep apnoea syndrome. Women (n = 126) had longer sleep latencies, greater amounts of slow wave sleep, and fewer awakenings during the night than men (n = 181), despite no differences in age, RDI (Respiratory Disturbance Index) or oxygen saturation. In a subgroup of men and women treated with nasal CPAP, gender differences generally persisted. There was no difference in the complaint of daytime sleepiness between the groups, but the women reported more fatigue during the day than the men, as well as complaining about more sleep disturbance at night. We interpret these differences in terms of known gender differences in sleep architecture and sleep complaints.

Hypersomnia (excessive sleepiness) refers to an increased sleep propensity with a subjective craving for sleep, involuntary naps and "sleep attacks" during the day and/or prolonged nighttime sleep with sleep drunkeness. Excessive sleepiness should be separated from fatigue and lack of energy associated with a variety of medical and psychiatric diseases. Hypersomnia is reported by 2-5% of the adult population and can lead to poor work, accidents and neuropsychiatric disturbances. Sleep apnea syndrome (SAS), narcolepsy, chronic sleep deprivation (insufficiency), and restless legs/periodic limb movements in sleep syndrome (RLS/PLMS) represent the most common causes of hypersomnia. The diagnosis of these conditions can often be suspected on clinical grounds. However, an overnight polysomnography and a multiple sleep latency test are often additionally required for definite diagnosis. Treatment options include nasal CPAP for SAS, stimulants for narcolepsy, sleep prolongation for sleep insufficiency, and dopaminergic agents for RLS/PLMS.

A 68-year-old female referred for excessive daytime sleepiness, strong morning headaches, snoring and suspected chronic fatigue syndrome. The polyMESAM examination was performed with following results: Respiratory Disturbances Index--RDI (average number of apnoeas and hypopnoeas in one hour of registration) 26, Oxygen Desaturation Index--ODI (average number of oxygen haemoglobin saturation drops in one hour) 51, basal oxygen haemoglobin saturation 90% and average oxygen haemoglobin saturation minimas 82%. Her condition was rated as grave OSAS. CPAP therapy was, however, impeded by anxiety state caused by claustrophobia. Analysis of lateral cephalogram proved significant constriction of the retrolingual posterior airway space to 6 mm (the bottom standard limit for women is 12 mm), with a relatively good position of the hyoid bone. The genioglossus advancement surgery was therefore performed on the patient as the only causational therapy. Then the patient referred improvement of sleepiness, snoring, fatigue and morning headache. PolyMESAM recorded two months after the surgery showed a strong improvement of OSAS: RDI 11, ODI 14, basal oxygen haemoglobin saturation 93% and average oxygen haemoglobin saturation minimas 89%.

(1) After negotiations with the Finnish Ministry of Social Affairs and Health, a national programme to promote prevention, treatment and rehabilitation of sleep apnoea for the years 2002-2012 has been prepared by the Finnish Lung Health Association on the basis of extensive collaboration. The programme needs to be revised as necessary, because of the rapid development in medical knowledge, and in appliance therapy in particular. (2) Sleep apnoea deteriorates slowly. Its typical features are snoring, interruptions of breathing during sleep and daytime tiredness. Sleep apnoea affects roughly 3% of middle-aged men and 2% of women. In Finland, there are approx. 150,000 sleep apnea patients, of which 15,000 patients have a severe disease, 50,000 patients are moderate and 85,000 have a mild form of the disease. Children are also affected by sleep apnea. A typical sleep apnea patient is a middle-aged man or a postmenopausal woman. (3) The obstruction of upper airways is essential in the occurrence of sleep apnoea. The obstruction can be caused by structural and/or functional factors. As for structural factors, there are various methods of intervention, such as to secure children's nasal respiration, to remove redundant soft tissue, as well as to correct malocclusions. It is possible to have an effect on the functional factors by treating well diseases predisposing to sleep apnoea, by reducing smoking, the consumption of alcohol and the use of medicines impairing the central nervous system. The most important single risk factor for sleep apnoea is obesity. (4) Untreated sleep apnoea leads to an increase morbidity and mortality through heart circulatory diseases and through accidents by tiredness. Untreated or undertreated sleep apnoea deteriorates a person's quality of life and working capacity. (5) The goals of the Programme for the prevention and treatment of sleep apnoea are as follows: (1) to decrease the incidence of sleep apnoea, (2) to ensure that as many patients as possible with sleep apnoea recover, (3) to maintain capacity for work and functional capacity of patients with sleep apnoea, (4) to reduce the percentage of patients with severe sleep apnoea, (5) to decrease the number of sleep apnoea patients requiring hospitalisation and (6) to improve cost effectiveness of prevention and treatment of sleep apnoea. (6) The following means are suggested for achieving the goals: (1) to promote prevention of obesity, weight loss and weight control; (2) to promote securing of nasal respiration in child patients and removal of obstructing redundant soft tissues; (3) to promote the correction of children's malocclusions, (4) to enhance knowledge about risk factors and treatment of sleep apnoea in key groups, (5) to promote early diagnosis and active treatment, (6) to commence rehabilitation early and individually as a part of treatment and (7) to encourage scientific research. (7) On the national level, the occurrence of sleep apnoea can be prevented, for example, by encouraging weight control. The programme gives examples of such measures and appeals to various authorities and voluntary organisations to reinforce their collaboration. Preventive measures should be individualised, and based on due consideration. (8) The efficacy of diagnosing sleep apnoea should be increased. Attention should be paid to the symptoms of risk group patients at different units of the primary and occupational health care. Even mild forms of the disease should be treated appropriately. Diagnosis and treatment of the disease involve cooperation between the primary and specialised health-care sectors. Methods of treatment are (1) treatment of obesity, (2) positional therapy, (3) reduction of the use of medicines impairing the central nervous system, (4) reduction of smoking and the consumption of alcohol, (5) devices affecting the position of the tongue and lower jaw, (6) treatment with Continuous Positive Airway Pressure (CPAP-treatment), (7) surgical methods of treatment and (8) rehabilitation. (9) The hierarchy of referrals in the prevention and treatment of sleep apnoea should be revised to accord a greater role to the primary health-care sector. Good exchanges of information and cooperation between the primary health care and specialised medical-care sectors should be developed. Hospitals districts in cooperation with provincial governments and municipalities should ensure that different levels of the health-care system are capable of fulfilling the tasks assigned to them appropriately. (10) Rehabilitation of sleep apnoea should be goal-orientated and cover all forms of rehabilitation: medical, occupational and social. Rehabilitation should prevent the effects caused by the disease. Thus, it is possible to support self-care, increase the patient's resources and improve quality of life. (11) Information and training should be directed primarily towards health-care personnel, patients and their families. Organisations should produce materials for health and patient education as well as organising training events. To support the activities. financing will be needed from organisations such as Finland's Slot Machine Association. The Social Insurance Institution should disseminate information about questions of social security. Regional direction and training will mainly be the responsibilities of hospital districts, provincial governments and local health centres. The media will play an important role in the dissemination in-depth information about prevention and treatment of sleep apnoea.

Sleep-related disturbed breathing and parasomnia in very young children are in the focus of epidemiological interest. The cardinal symptom, i.e. snoring, in connection with nocturnal perspiration, mouth breathing, susceptibility to infection of the upper respiratory tract and tiredness during the day or hypermotility, can be an indication of obstructive sleep apnea (OSA). The common treatment is adenotomy unless there is indication of allergic swelling of the nasal mucous membrane. Other anatomic predispositions for OSA must be considered (tonsillar hypertrophy, midfacial hypoplasia, micro- and retrognathia, e.g. in patients with Down's syndrome or patients with preoperated cleft lip face palate). Inhalative nasal corticoids are a possible alternative to adenotomy in light to medium grade cases of OSA. Tonsillotomy is indicated only in serious OSA cases, tonsillectomy is only justified in cases of chronic tonsillitis or more than 4-6 cases of angina in the last 12 months. Treatment with nasal CPAP is tolerated well also in childhood. Patients with central hypoventilation syndromes, insufficiency of the respiratory musculature or obesitas hypoventilation syndrome can usually be ventilated by non-invasive approach using a nasal mask. Patients suffering from parasomnia should always be asked if they snore at night because if OSA is diagnosed and treated, there are very good prospects of curing somnambulism as well. Like with narcolepsy and REM sleep, a close HLA association has also been identified for family somnambulism. In cases of parasomnia which becomes manifest only after very young age frontal lobe epilepsy should be suspected and searched by polysomnographic and simultaneous continuous nocturnal video surveillance. If reversive development or unclear motoric and utterance phenomena are observed, sleep-bound convulsive disorder should be looked for. Syncopal events can require comprehensive cardiological diagnosis, including exclusion of nightly disorders of the cardiac rhythm.

OSA syndrome is characterized by recurring episodes of upper airway (UA) obstruction during sleep. The UA is subjected to collapse when the negative airway pressure generated by inspiratory activity of the diaphragm and intercostal muscles exceeds the force produced by the UA dilating muscles. Factors that reduce UA calibre lead to increased UA resistance with the generation of a more negative pharyngeal pressure during inspiration, and thereby predispose to UA occlusion during sleep. As a consequence, UA dilating muscles must contract more forcefully to maintain a patent UA, which may predispose to fatigue. Nasal CPAP counteracts these collapsing forces and is associated with resting of the UA muscles. The more recent development of auto-adjusting CPAP (APAP) is a reflection of the understanding that the pressure required to prevent UA collapse fluctuates throughout the night and results in a lower mean pressure that may be more comfortable for some patients. The predominant morbidity of the OSA syndrome is cardiovascular and there is growing understanding of the basic mechanisms involved. Intermittent hypoxia appears to play a central role by activating transcription factors that predispose to atherogenesis, particularly NFkappaB. Sympathetic overactivity also appears to play an important role but the mechanisms involved are unclear.

The Nozovent nostril dilator improves nasal breathing to the same degree as topical decongestants and reduces mouth dryness at night in 51% of nocturnal mouth breathers. It does not help every snorer but reduces the snoring heard by the sleeping partner in about 50%, improves the respiratory disturbance index significantly in 19% and gives less morning and daytime tiredness in 40% of snorers. The medium CPAP pressure can be significantly reduced with the dilator.

We report the case of a 47-year-old man with idiopathic central sleep apnoeas recurring during wake-sleep transitions at night or at diurnal naps. Symptoms associated with central apnoeas were sudden awakening with shortness of breath, sleep fragmentation and daytime tiredness. Following the failure of CPAP and BiPAP, we treated the patient with zolpidem which reduced central apnoea events, improved sleep and eliminated the patient's nocturnal disturbing symptoms. Beneficial effects were still present after two years of treatment. Our case demonstrates that zolpidem may be beneficial in the long term treatment of idiopathic central sleep apnoea syndrome.
