A 71-year-old man was noted to habitually snore loudly at night and have a predisposition to somnolence during the daytime. While dozing during the day, he developed cardiac arrest at the time when snoring stopped, and was resuscitated. By means of a respiration monitor, he was diagnosed as having sleep apnea syndrome (SAS) with a combination of obstructive, central, and mixed type. However, neither respiratory insufficiency nor cardiac insufficiency was observed, and there were no abnormal findings on laboratory tests and bronchoscopy. SAS complicated by cardiac arrest is usually seen in cases with concomitant symptoms such as excessive obesity, hypertension, arrhythmia, right heart insufficiency, secondary polycythemia, or mental disorder. The present case abruptly developed cardiac arrest in the absence of such symptoms. This case therefore suggests the importance of screening tests using a respiration monitor during sleep in subjects who have a loud snore or a predisposition to somnolence during the daytime. Although treatment with UPPP alone had no noticeable effect, UPPP treatment combined with sleeping in the lateral position was effective in the present case. The efficacy rate of UPPP has been reported to be 50 to 60%. The early establishment of a method for precise evaluation of the site of obstruction as well as criteria for appropriate application of UPPP are urgently required.

Obstructive sleep apnea syndrome was first described 200 years ago but the definition of the syndrome was only developed during the last ten years (snoring, apneas during the night, somnolence, high blood pressure, changes of personality). The frequency of the syndrome is not known exactly but the pathophysiology, the morbidity and the mortality associated with the syndrome is facilitating by application of a positive airway pressure (CPAP) at the nose. Good compliance and rapid improvement of the symptomatology with practically no complications make that CPAP is the first choice for the physician in 1991.

In order to determine whether the clinical features of obstructive sleep apnoea (OSA) are the same in men and women we reviewed the records of 22 women with OSA. The women were matched with 44 men of similar age (+/- 5 years) and frequency of respiratory events (less than or equal to 15/hr, 16-40/hr, 41-70/hr and greater than 70/hr). The degree of daytime somnolence was similar in men and women. Women are more likely than men to complain of morning fatigue and morning headache, and less likely to report restless sleep or to have been told of apnoea during sleep. Difficulty initiating sleep (DIS) was twice as common in women as in men (p less than 0.05). Most of these differences were also seen when women and men who snored but did not have OSA were compared. Arterial hypertension was less common in women (3/22) than in men (18/44), (p less than 0.001). More striking than the differences between men and women in the prevalence of single symptoms was the existence of a subgroup of women (9/22) with no complaint of either apnoea, choking arousals or restless sleep, and normal blood pressure, complaining only of fatigue and morning headache, and in three cases DIS as well. We concluded that OSA may be commoner in women than previous reports suggest, and that the clinical features may be misleading in women.

The case history of a 65 year old female patient has been reported here by the authors. The patient was admitted to the Intensive Therapy Unit owing to her repeated heart pain. Later she was transferred to the Department of Medicine to establish the exact diagnosis. Prepyloric ulcer and hypertension were occurred in her history. The symptoms of her preceding as well as her recent illness were: pain in epigastric field, nausea, adynamia, weakness, polyuria, significant loss of weight, somnolence and the shortened Q--T time in electrocardiogram related to hypercalcemia syndrome. The calcium value in blood proved to be at critically high level from time to time. The possibility of the secondary hypercalcemic state was excluded by sonographic examination and the elevated level of parathormone in blood established the diagnosis of the hyperparathyroidism. The surgical resection of parathyroidic adenoma yielded a complete recovery of the patient. The authors call the attention to the significance of the clinical signs in the diagnosis of the disease.

Twenty-seven morbidly obese patients (13 men and 14 women) with body mass index greater than or equal to 40 kg m-2 were examined. The mean age of the subjects was 36.9 +/- 8.2 years (range 23-51 years), and the mean BMI was 50.2 +/- 6.2 kg m-2 (range 40.0-62.9 kg m-2). A whole-night sleep recording was made for all patients with signs or symptoms indicative of possible obstructive sleep apnoea syndrome (OSAS). If the first nocturnal sleep recording was abnormal, it was controlled after 1 year. Eleven (10 men and one woman) of the 27 patients had an oxygen desaturation index (ODI) of 10 h-1. They were symptomatic with excessive daytime sleepiness or other daytime symptoms of OSAS. The occurrence of OSAS in men and women was 76.9 and 7.1%, respectively. Arterial hypertension was associated with OSAS, but not with smoking or the degree of obesity. Antihypertensive treatment was received by nine of the 27 patients; six of them had OSAS. Thus six of the 11 (54.5%) patients with OSAS and three of the 16 (18.8%) nonapnoeic patients were treated for arterial hypertension (Fisher exact test, P = 0.042). The odds ratio of OSAS for arterial hypertension is 5.2 (95% CI, 0.71-43.6). Vertical-banded gastroplasty was performed in 14 patients, three of whom had OSAS. The selection of patients for gastroplasty was made without taking into account the results of sleep recordings. In the three OSAS patients, a 30-38% reduction in BMI was achieved by surgery. Eight patients with OSAS were treated with an intensified dietary regimen, and the reduction in BMI ranged from -2.6 to 33%. OSAS was either cured or significantly improved in six (55%) patients, with a mean reduction in BMI of 27%, while in patients with persistent OSAS the mean reduction in BMI was only 7%.

To determine if a history of snoring is a risk factor for brain infarction, I conducted a case-control study of risk factors for ischemic stroke using 177 consecutive male patients aged 16-60 (mean 49) years with acute brain infarction. For each patient I chose an age-matched (+/- 6 years) male control. Arterial hypertension, coronary heart disease, snoring (habitually or often), and heavy drinking (greater than 300 g/wk) were risk factors in the stepwise multiple logistic regression analysis. The odds ratio of snoring for brain infarction was 2.13. By McNemar's test this association increased strongly if a history of sleep apnea, excessive daytime sleepiness, and obesity were all present with snoring (odds ratio 8.00). My study indicates that snoring may be a risk factor for ischemic stroke, possibly because of the higher prevalence of an obstructive sleep apnea syndrome among snorers than nonsnorers.

Severe complications involving the central nervous system occurred in 7 of 36 children (19%) after renal transplantation. The children, aged 1.6-13.1 years at transplantation were treated with ciclosporin and prednisolone. Six of them had azathioprine as well. The neurological symptoms consisted of seizures, drowsiness, confusion, hallucinations, visual disturbances, and mental changes. In all cases electroencephalograms were severely pathological, showing diffuse abnormalities with or without focal abnormalities and epileptic activity. In all but one case the ciclosporin trough blood levels were within the therapeutic range. Blood glucose and electrolytes were normal. Several factors might contribute to the central nervous system complications: ciclosporin, corticosteroids, hypertension, rejection, and as yet unknown ones.

Violent shaking causes severe injury in infants, but the diagnosis of shaken baby syndrome is often difficult to make because of the lack of obvious external signs. Consultations by other specialists may not be helpful, since the findings of most organ systems, taken in isolation, are usually nonspecific. Shaken baby syndrome should be considered in infants presenting with seizures, failure to thrive, vomiting associated with lethargy or drowsiness, hypothermia, bradycardia, hypertension or hypotension, respiratory irregularities, coma or death. Shaken babies are usually less than one year old, and most are under six months of age. Head injury (notably subdural hemorrhage) and retinal hemorrhages are the hallmarks of the syndrome.

Patients (n = 150) were randomized to a 6-week, double-blind study to evaluate the relative efficacy and safety of mirtazapine, amitriptyline, and placebo in the treatment of major depressive disorder symptoms. Average daily modal doses were mirtazapine, 18 mg; amitriptyline, 111 mg; and placebo, 4.6 capsules. Mirtazapine- and amitriptyline-treated patients had statistically significantly greater mean Hamilton Rating Scale for Depression (HAM-D) score reductions (weekly visits 1, 2, 4, and endpoint) compared to placebo. These findings were supported by the Montgomery-Asberg Depression Rating Scale (MADRS); the Zung Self-rating Depression Scale (SDS); and the Clinical Global Impressions (CGI) scales. Somnolence and weight gain were the only adverse clinical experiences (ACEs) reported substantially more often by mirtazapine-treated patients than by those in the placebo group. However, more amitriptyline-treated patients reported decreased visual accommodation, dry mouth, dyspepsia, constipation, tachycardia, hypertension, hypotension, discoordination, dizziness, and tremor than mirtazapine- or placebo-treated patients. Results of this study indicate that mirtazapine is more effective than placebo in the treatment of these patients, and superior to amitriptyline in respect to anticholinergic and cardiovascular effects.

A 39-year old Chinese man presented with an acute onset of severe headache, accelerated hypertension and subsequently an unexpected extensive right occipital haemorrhage. These were found to be related to a sleep apnoea syndrome which had been unrecognized for many years despite its typical symptoms of loud snoring and excessive daytime sleepiness. Weight reduction led to significant clinical but not polysomnographic improvement of the sleep apnoea syndrome.
