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.

Factors associated with mortality were examined for 27,370 hip fracture patients aged 65 years or older in Maryland hospitals, using discharge data for 1979-1988. Variables of interest included sociodemography, principal medical and injury diagnoses, E-code, year, disposition, and hospital. For both white males and white females, the hip fracture rate doubled with each 5-year increment in age. The overall proportion who died during hospitalization was 4.9% (n = 1,339). After multivariate adjustment, there remained a substantially increased risk of death for males. The relative odds (RO) of dying for males versus females were 1.6. Other factors associated with high relative odds of dying during hospitalization included the diagnosis of septicemia (RO = 12.3), pneumonia/influenza (RO = 4.9), and digestive system disorder (RO = 3.6). The RO of dying doubled in the presence of cardiac, neoplastic, or cerebrovascular disease. Patients with diagnoses of nervous system or mental disorder, hypertension, anemia, musculoskeletal system disease, or urinary tract infection were at decreased risk of dying. Results of the study suggest that the prevention or early diagnosis and treatment of serious infections in the elderly patient with a hip fracture remain an important challenge to clinicians.

To study past histories of patients who died suddenly, we selected cases from all the summary death certificates in which death occurred within 24 hours from the onset of symptoms spanning 1984 to 1986 in Niigata prefecture with a population of 2.5 million. We then re-examined all information on the death certificates to determine the underlying causes. Sudden deaths due to cardiovascular diseases other than acute myocardial infarction and cerebrovascular accident (OCD) accounted for the largest proportion (51.4%). The proportion of death of unknown etiology increased with the decrease in age in both sexes aged 15 to 54 years, accounting for 67.8% in males and 51.1% in females. The number of cases with histories of diseases related to atherosclerosis (e.g. hypertension, old cerebrovascular accident, etc) increased with age in both sexes, accounting for 38.5% in males and 36.4% in females, both aged 75 years old and over. Except diseases related to atherosclerosis, the past histories accounted for 2.5% or greater were as follows: alcoholism (4.1%), psychiatric disorder (PSY, 2.9%) and valvular heart diseases (VD, 2.6%) in 15-54-year-old males; ischemic heart diseases (IHD, 9.4%), arrhythmia without organic heart diseases (ARR, 2.5%) and VD (2.5%) in 55-74-year-old male; IHD (11.4%), bronchial asthma (3.7%), common cold within one month (CC, 3.6%), cor pulmonale or its related diseases (3.0%) and ARR (2.6%) in male of 75 years old and over; PSY (8.7%), IHD (5.8%), VD (5.1%), pregnancy, delivery or related diseases (4.4%), chronic renal failure (3.6%) and CC (2.9%) in 15-54-year-old females; IHD (10.2%), VD (3.2%) and ARR (2.6%) in 55-74-year-old females; and IHD (11.8%) in females of 75 years old and over. When diseases related to atherosclerosis were included, half of the sudden death cases due to OCD had past histories of underlying cause. As descriptions of past histories are often incomplete, there were probably more cases with past histories. The results of this study indicate that investigation of past histories may aid in elucidating and preventing sudden death.

Post-traumatic stress disorder (PTSD) was studied in the Piedmont region of North Carolina. Among 2985 subjects, the lifetime and six month prevalence figures for PTSD were 1.30 and 0.44% respectively. In comparison to non-PTSD subjects, those with PTSD had significantly greater job instability, family history of psychiatric illness, parental poverty, child abuse, and separation or divorce of parents prior to age 10. PTSD was associated with greater psychiatric comorbidity and attempted suicide, increased frequency of bronchial asthma, hypertension, peptic ulcer and with impaired social support. Differences were noted between chronic and acute PTSD on a number of measures, with chronic PTSD being accompanied by more frequent social phobia, reduced social support and greater avoidance symptoms.

This study examined the physical complaints, mental complaints and psychiatric disorders in software engineers. Subjects were 101 male software engineers. They were evaluated by a semistructured interview. Psychiatric diagnosis was based on DSM-III (Diagnostic and Statistical Manual of Mental Disorders, third edition). The results are summarized as follows: 1) Physical complaints were observed in 68% of the subjects with 25% of the subjects complaining of physical ill-health. This study showed that 12% of the subjects had hypertension, 12%, gastritis or gastro-duodenal ulcer, 14%, allergic disease, and 19% miscellaneous diseases. 2) Of the subjects 62% had mental complaints and 31% mental ill-health. Depressive symptom was the most frequent mental complaint with 32% of the subjects diagnosed as DSM-III. The common diagnoses were adjustment disorders (19%), major affective disorders (6%), psychological factors affecting physical condition (5%) and dysthymic disorder (3%). Only one subject sought professional help from a psychiatrist for relief of mental complaints. The data suggest the severity of mental ill health in software engineers, but methodological limitations preclude a firm conclusion at this time. Further studies should be made on the mental health state in software engineers.

Vascular dementia is the second most common type of dementia in the elderly after the dementia of Alzheimer's disease. Six forms of vascular dementia have been described: multi-infarct dementia, lacunar dementia, Binswanger's subcortical encephalopathy, cerebral amyloid angiopathy, white-matter lesions associated with dementias, and single-infarct dementia. Each is described. Severe dementia is found in 5% of persons over age 65 and in 15% to 20% of persons over age 80 years. Alzheimer's disease accounts for 50% to 60% of cases of severe dementia and vascular dementia for 10% to 20%; 20% of the patients have both disorders. The incidence of vascular dementia, which seems to be declining, is about 7/1,000 persons/year. Hypertension is the most powerful risk factor for all vascular dementias. Vascular dementias can be accurately diagnosed by using clinical and mental state examinations, Diagnostic and Statistical Manual of Mental Disorders criteria, ischemic scores, and computed tomography or magnetic resonance imaging. The most successful treatment of vascular dementia is the prevention of cerebral infarcts. Study of the incidence of vascular dementias and their treatment will be included in the European Trial on Systolic Hypertension in the Elderly (SYST-EUR) of 3,000 elderly hypertensive patients.

A stratified random sample of 83 black and 81 white community residents aged 65 years and older in a five-county area in the Piedmont region of North Carolina was evaluated for dementia, using the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, and the National Institute of Neurological Disorders and Stroke--Alzheimer's Disease and Related Disorders Association criteria. Of 164 subjects, 26 were found to be demented, resulting in an estimated prevalence rate of dementia in the five-county area of 16% (95% confidence interval, 7.92 to 24.08) for blacks and 3.05% (95% confidence interval, 0 to 6.91) for whites. The estimated prevalence of dementia for white women (2.9%) was similar to that for white men (3.3%), but the rate for black women was distinctly higher than for black men (19.9% and 8.9%, respectively). Blacks were more likely than whites to have a history of stroke, hypertension, and other chronic disorders that might have contributed to the development of dementia. Apart from differences in rates of institutionalization, no other relevant factors were identified that might explain the difference in the prevalence of dementia in these black and white community residents.

The authors studied data on psychiatric disorders and eight chronic medical conditions in a community sample of 2,554 persons. The sex- and age-adjusted prevalence of any psychiatric disorder in the preceding 6 months was 24.7% and of lifetime psychiatric disorder was 42.2% among persons with one or more medical conditions, compared to 17.5% and 33.0%, respectively, for persons with no medical condition. Persons with chronic medical conditions were more likely to have lifetime substance use disorders and recent affective and anxiety disorders. Arthritis, cancer, lung disease, neurological disorder, heart disease, and physical handicap were strongly associated with psychiatric disorders, but hypertension and diabetes were not.

Prevalence of medical disorders was determined for 10,758 consecutive admissions for inpatient alcoholism treatment to 13 hospitals located in eight states of the United States. The majority of patients (approximately 70% of the men and 73% of the women) had a significant medical problem other than alcoholism. The most prevalent disorders were diseases of the liver, gallbladder and pancreas; bronchitis; emphysema; and asthma. Hypertensive disease was found in 15% of the men and 7% of the women. Psychiatric disorders associated with alcoholism were neuroses, personality disorders and other nonpsychotic states. Less than 10% of all patients were referred by physicians; more than 90% had not been previously diagnosed or treated for medical or psychiatric disorders associated with alcoholism. The high prevalence of medical disorders indicates that inpatient treatment of alcoholism should be undertaken in facilities that have expertise and resources for concurrent treatment of serious medical illness.

The aims of this study were to determine the prognosis for women with different symptoms and signs indicating ischaemic heart disease and to relate entry characteristics to events of ischaemic heart disease and stroke, and to overall mortality during a 12-year follow-up period. A prospective cohort study was started as a cross-sectional investigation in 1968-69 (1462 participants aged 38-60, participation rate 90.1%). The same sample was re-studied in 1980-81 (1154 participants, participation rate 78.9% of those studied in 1968-69). In addition, a clinical series comprising all women of similar age in Gothenburg with myocardial infarction during the years 1968-70 (47 women) was followed up for 12 years. The 12-year overall mortality rate for women with initial myocardial infarction in the clinical series was 45%. The 12-year overall mortality rates for women who at the time of the initial study either were considered to have angina pectoris or showed electrocardiographic changes indicating ischaemic heart disease at rest or at work were 10%, 17% and 10% respectively (expected figures 7%, 12% and 10%). Twenty-three women (1.6%) developed myocardial infarction during the follow-up period (8 fatal, 15 non-fatal). New symptoms of angina pectoris were recorded in 56 women (4.0%), new electrocardiographic changes indicating ischaemic heart disease in 73 women (6.0%), and new signs of stroke in 13 women (0.9%). Altogether 75 women (5.1%) died during the follow-up period. These five end-points were taken into consideration. Women with previously untreated arterial hypertension were offered control visits during the follow-up period and were prescribed antihypertensive drugs when clinically indicated. In this group of women, hypertension was not a predictor for any of the end-points. No other systematic intervention was carried out. Increased abdominal adiposity, increased serum triglycerides and low peak expiratory flow were independent predictors of at least three of the end-points studied: myocardial infarction, stroke and death. Increased abdominal adiposity was also an independent predictor of angina pectoris. Initial diabetes was an independent predictor of both myocardial infarction and of death. Low energy intake predicted myocardial infarction and electrocardiographic changes indicating ischaemic heart disease. High serum gastrin levels predicted myocardial infarction. Low education and high degree of mental disorder were independent predictors of angina pectoris. Physical inactivity at leisure and physical inactivity at work were independent predictors of stroke and of death, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)
