Criterion-related validity of a new measure of functional ability was conducted according to a causal model based on conceptual models employed in the area of rehabilitative and geriatric medicine. The criteria variables included concurrent diagnosed diseases, global self-rated health, drug consumption and general practitioner (GP) consultations. The measure of functional ability was developed with the intention of achieving a high degree of discrimination among a group of community dwelling elderly. Data were derived from a sample survey of 70-year-old men and women conducted in 1984 in the county of Copenhagen (Denmark). Altogether 366 men and 368 women participated in each of the two phases of the study--a comprehensive medical examination at the county hospital at Glostrup followed by a home visit conducted by an occupational therapist 1-2 weeks later. The analysis included four different unidimensional index scales of functional ability divided into two types, with reduced speed and tiredness as subdimensions. The two scale types were mobility function and lower limb function. Early losses of ability together with global self-rated health were treated as outcome measures of diagnosed chronic diseases. At the same time these outcome measures together with diagnosed diseases were considered to predict drug consumption and GP consultations. It was shown that functional ability as measured by the new index scales were strongly influenced by diagnosed diseases: arteriostenosis and osteoarthrosis in lower extremities, obesity, shoulder impairments and bronchitis among women, and glucose intolerance, arteriostenosis in lower extremities and shoulder impairments among men. Global self-rated health was strongly associated with the new functional ability rating system. Early losses of ability but not self-rated health was a strong predictor for drug consumption and frequent contacts with GP. It is concluded that the new measure of functional ability is suitable for health studies of community dwelling elderly, in particular as a summary statement of the individual's health status.

In order to elucidate factors affecting taxi drivers health, a questionnaire survey was performed on 5523 taxi drivers and health examinations were conducted on 311 taxi drivers from among them. Analysis by a method of multivariate analysis called Quantification II was performed with dependent variables being blood pressure, the number of subjective symptoms and fatigue on rising, and independent variables being work and daily life conditions. The major results of this survey were as follows: 1) A tendency for hypertension risk to increase with degree of obesity, and both employment as a taxi driver for 1-4 years and over twenty years of taxi driving were positively associated with increase in risk for hypertension. 2) Common factors to all types of work shifts which were related to an increase in the number of subjective symptoms were irregularity of meals, insufficient rest on off days, large number of years engagement at taxi driving, frequent frightening experiences while driving and comparatively short driving distance in one shift. 3) Common factors to all types of work shifts that were connected with fatigue at the time of rising were insufficient rest on off days and long years engagement in taxi driving.

A young Japanese female demonstrated unusual features of Cushing's syndrome, cardiac myxomas and mucocutaneous lentigines. At the age of 12 years she presented with growth failure and obesity. The dexamethasone suppression test, the metyrapone test and low corticotropin concentrations indicated a primary adrenal disorder. At surgery, the adrenal glands were not enlarged (the right, 4.0 g; the left; 4.5 g) but had numerous small dark brown nodules. The pathological findings showed multiple small black cortical nodules containing large cells with eosinophilic cytoplasm and lipofuscin, and internodular cortical atrophy. These abnormalities were consistent with primary pigmented nodular adrenocortical disease. At age 22 years she complained of fatigue and palpitations associated with mid-chest pain. Four cardiac myxomas, suspected from the echocardiogram, were surgically removed. Because Cushing's syndrome and cardiac myxomas are life-threatening conditions, an awareness of the complex is important.

Adiposis dolorosa or Dercum's disease consists of a painful progressive localized state of obesity with four cardinal symptoms: a) painful circumscribed or diffuse fatty deposits, b) generalized obesity in women usually of menopausal age, c) asthenia, weakness and frequently tendency to fatigue and d) mental phenomena including emotional instability, depression, epilepsy, mental confusion and true dementia. Only a few cases in men have been described. The pain may be treated with intravenous administration of lignocaine or oral mexitil while no causal treatment is known. An illustrative case is reported.

Hypothalamic tissue levels of nine regulatory peptides (bombesin, calcitonin gene-related peptide [CGRP], galanin, neuromedin B, neuropeptide Y [NPY], neurotensin, somatostatin, substance P, and vasoactive intestinal peptide [VIP]) were compared in Aston obese diabetic (ob/ob) and lean (+/?) mice aged 4, 16, and 28 weeks. Neurotensin concentrations were significantly lower in ob/ob mice than in lean mice, with a 20% reduction (P = .03) in the whole hypothalamus at 4 weeks of age, a 24% reduction (P = .009) in the lateral hypothalamus at 16 weeks, and a 50% reduction (P = .0007) in the central hypothalamus at 28 weeks of age. Apart from a 42% increase in vasoactive intestinal peptide concentrations in the central hypothalamus of ob/ob mice at 28 weeks (P = .02), levels of the other eight peptides examined did not differ significantly between obese and lean groups. Neurotensin is known to cause anorexia and increased energy expenditure when injected into the central hypothalamus. Reduced hypothalamic neurotensin concentrations may reflect reduced neurotensinergic activity, which might contribute to hyperphagia and decreased energy expenditure, two major defects that contribute to obesity and diabetes in the ob/ob syndrome.

In order to examine whether there are sex-differences in the response of energy balance to physical training slightly obese men and women participated in the same 3 months physical training program with the same individual relative intensity. The men became somewhat lighter (-2 kg) and leaner (-2.9 kg body fat) and showed decreases in sum of insulin and sum of C-peptide values during an oral glucose tolerance test as well as cholesterol values. The women showed decrease of 2.6 kg body fat, and also increased lean body mass (1.9 kg) and similar metabolic changes. The women had, however, a larger body fat mass at the outset. When women with similar body fat mass as that of men were analysed separately, no change in body weight or body fat had occurred, and the metabolic adaptations were less pronounced. No compensatory increase of energy intake could be discovered in any of the groups, the most obese women actually showed a decrease. Taken together with previous information these results suggest that men, like male rats, become leaner during physical training due to a lack of energy intake compensation. Women with similar body fat mass, however, like female rats, may react with such a compensation, causing a protection of their body fat. Women usually have more body fat than men, however. Obese women in this study showed a decrease of body fat.

A 61-year-old woman with low grade obesity index complained of general fatigue. Cardiomegaly had been present since the age of 45. According to a roentgenogram on admission, her cardia-thoracic ratio was 61%. Pericardial effusion was strongly suspected because of extra echo spaces on both posterior and anterior walls, and unsynchronized echocardiograph waves of epicardium and pericardium. However, values of dynamic CT measured at areas equivalent to the extra echo spaces were -120. On admission, T1-emphasized MRI image showed a high signal density in those areas. After significant weight reduction, the abnormal values and signs of the clinical examinations, as well as the patient's complaints were attenuated or disappeared. Together with these results, cardiomegaly of the patient was diagnosed to be due to excessive fat deposit between the epicardium and cardiac muscle. Dissociation between mildness of obesity index and excessive deposition of fat in the pericardium was discussed from the point of view of body mass index and time course of fat deposition.

The relationship of solvent exposure to self-reported neurologic and somatic symptoms as well as neuropsychological performance was examined in a sample of 567 female blue collar workers who were members of the International Brotherhood of Electrical Workers (IBEW). Structured interviews were conducted at IBEW offices. Five solvent exposure categories were derived--never exposed, exposed prior to but not during the past year, exposed during the past year but not currently, currently exposed less than 50% of the time, and currently exposed more than 50% of the time. No differences among the groups on neuropsychological performance were found. On the other hand, heightened exposure was significantly related to depression, severe headaches, light-headedness, room spinning, appetite difficulties, funny taste in mouth, weakness/fatigue, rashes, and abdominal pain after controlling for the effects of seven risk factors (age, smoking, moderate-heavy alcohol consumption, severe obesity, history of physician-diagnosed chronic illness, working in a clean room, and exposure to other chemicals). These findings are consistent with Scandinavian studies of solvent-exposed male workers and point to the need for careful prospective research.

International study of the effect of dexfenfluramine in obesity (ISIS): 6 months results. ISIS is a multicentre therapeutic trial of the "intention to treat" type organized to test the effectiveness and side-effects of dexfenfluramine combined with diet in the treatment of obesity. This was a randomized, double-blind drug versus placebo study programmed for a one-year period. Eight hundred and twenty-two obese patients were included. Dexfenfluramine was administered in doses of 15 mg b.d. The intermediate results after 6 months of treatment are presented. Significant differences were observed between the dexfenfluramine group (n = 404) and the placebo group (n = 418). In the treated group: 1) the drug withdrawal rate was lower, mainly due to a greater number of patients in the placebo group dissatisfied with their weight loss; 2) about twice as many patients achieved an important loss of weight in terms of percentage of the initial weight or overweight; 3) the cumulative loss of weight was greater; 4) there was a higher incidence of transient side-effects, such as fatigue, diarrhoea, dry mouth, polyuria and drowsiness. These results suggest that dexfenfluramine will be suitable for a more prolonged treatment of obese patients, in addition to diet.

The preventive role of the occupational practitioner and occupational medicine no longer has to be demonstrated. As far as cardiovascular risk factors are concerned, on the one hand there are a certain number of cardiovascular diseases which have their origin in certain occupational fields (this concerns 10 pictures of occupational diseases which are entitled to compensation) and, on the other hand, occupational medicine has an important role to play when faced with the usual cardiovascular risks such as sedentary life style, obesity or excess weight, alcohol, tobacco, diabetes, fatigue and stress. Apart from giving advice to employees (health education) and instantly replying to the risk by individual or collective prevention and by medical and technical prevention, there is epidemiological observation and the investigation of quantitative or quantifiable "indicators". All these roles imply interdisciplinary dialogue and community participation so as to be able to counteract environmental hazards, rehabilitate vulnerable subjects, and develop health.
