The clinical courses of 60 children suffering from ulcerative Colitis (UC, n = 21) and Crohn's disease (CD, n = 39) were investigated over a period of 8.7 and 5.1 years respectively. At the time of diagnosis all UC-patients showed mucohemorrhagic feces. Relapses often occurred after emotional stress and in 81% of all patients during the winter season. Typical late complications were arthritis (6/21), osteoporosis (6/21), allergic diseases (8/21) and diabetes mellitus (2/21). However, the psychosomatic development appeared normal in at least 17/21 of these patients. Generally the courses in children with CD were more serious. Despite intensive therapy 15/39 children developed an intestinal stenosis which was followed by bowel resection in 11 of them. Further complications were fistulas (6/39), abscess-formations (4/39) and osteoporosis (12/39) due to steroid therapy. Only 12/39 showed a significant catch-up growth. Interviews and psychological tests revealed that CD-patients were introverted with strong connections to their families. Equally they longed for approval and social contact with their contemporaries.

More and more people are turning to exercise as a means of achieving long-term health. The World Health Organization has endorsed this concept. The best available evidence suggests that an employee fitness programme will result in decreased health-care costs, decreased absenteeism and increased productivity for the employer. Regular physical activity is also associated with lower mortality rates. Appropriate physical activity may be a valuable tool in therapeutic regimens for the control and amelioration (rehabilitation) of cardiovascular disease, coronary artery disease, hypertension, congenital heart disease, peripheral vascular disease, obesity, chronic obstructive pulmonary disease, diabetes mellitus, musculoskeletal disorders, end-stage renal disease, stress, anxiety and depression, etc. Regular physical activity, independent of other factors, reduces the probability of coronary artery disease and early death. Patients with risk factors for coronary artery disease need more intensive preexercise evaluation than those not a risk, and those with known or suspected cardiovascular disease need the most intensive evaluation and follow-up. Participation in vigorous sports activities, such as jogging, swimming, tennis, etc., helps to protect against the development of hypertension, even when other predisposing factors are present. Several studies have been conducted on the use of exercise in the treatment of hypertension. Physical exercise also contributes to the control of body weight. Consideration of the metabolic abnormalities in patients with type II (adult onset) diabetes indicates that they would make excellent candidates for an exercise programme. Osteoporosis is an important health problem for the elderly. The best treatment available at present is prevention, and a high level of physical activity throughout life can result in a larger skeletal mass during old age.(ABSTRACT TRUNCATED AT 250 WORDS)

The results are presented of a controlled study in male Wistar rats into the effects of 24R,25-dihydroxyvitamin D3 on blood glucose levels, bone calcium content and ADP-induced platelet aggregation in streptozocin-induced diabetes mellitus. Blood glucose levels were shown to be decreased by 10 micrograms/kg 24R,25-dihydroxyvitamin D3. The reduced bone calcium content associated with diabetes mellitus was returned to normal levels with both 1 and 10 micrograms/kg 24R,25-dihydroxyvitamin D3. It was also shown to exhibit dose-dependent anti-platelet activity. The data suggest that 24R,25-dihydroxyvitamin D3 might have potential as a mild therapeutic agent in the treatment of osteoporosis and platelet hyperactivity associated with diabetes mellitus.

The side effects and health risks associated with contraceptive pills have been explained by the metabolic changes they produce. The steroids in them affect the metabolism of hormones, vitamins, trace elements, carbohydrates, proteins and lipids. The changes, however, are minimal, and the steroid content has decreased over the years. The liver toxicity of currently used pills is small. Serum amino transferase values need to be checked once during the 1st 3-6 months of use, although routine liver tests have been halted. Contraceptive pills cause fluid retention and weight increase because of the estrogens. Progestin increases the secretion of water and natrium. Osteoporosis, however, does not develop. Contraceptive pills do not cause diabetes, although blood sugar increases more than average during the glucose tolerance test. Some progestins have a poor anabolic effect. The ethinylestradiol pill increases the content of some liver-based proteins in the circulation. Smoking is an important risk factor because it increases changes in the content of coagulation factors and antithrombin III. The progestin component determines the effect of the pill on lipoproteins. Changes in the cholesterol and triglycerides have remained minimal, as the estrogen-progestin content of the pill has been decreased. A new product that acts antiandrogenically has been developed for contraception by those suffering from acne.

A 44-year-old Chinese male with a 7-year history of diabetes developed spontaneous fractures affecting the femur and distal tibia and fibula within a period of 4 months. Spontaneous rib fractures were also present. There was additional evidence of extensive tissue damage with retinopathy, proteinuria, necrobiosis lipoidica diabeticorum, peripheral neuropathy and autonomic neuropathy. Investigation confirmed the presence of generalised osteoporosis and showed no evidence of other metabolic bone disease or abnormal vitamin D metabolism. Mild hypogonadism was also present and investigation suggested a disturbance of hypothalamic-pituitary control of gonadal function. It is suggested that the severe generalised osteoporosis resulted from poorly controlled diabetes with a possible additional contribution from androgen deficiency secondary to the diabetes.

Double photon absorptiometry comparison was done of lumbar bone mineral content (BMC) values in 40 women with well-compensated non-insulin-dependent diabetes mellitus (type II) and on dietary and/or oral hypoglycemic treatment, and 35 age-matched non-diabetic women, to determine the presence and degree of osteoporosis in this type of diabetes by means of a highly precise and sensitive method. No difference between the two groups was noted as regards blood calcium, phosphorus, PTH and thyrocalcitonin, and urinary calcium and phosphorus. BMC, on the other hand, was significantly lower in the diabetics, both in L2,L3,L4 and in L4 alone. No significant difference could be discerned between patients on diet and those on drugs. It can thus be maintained that osteoporosis is a possible complication of type II diabetes and may appear even in the absence of its classical complications.

Present-time Greenlanders are living a stressful 'westernized life' complete with an elevated consumption of tobacco and alcohol. The drinking water in Greenland is extremely soft and the diet is very low in calcium (and probably magnesium) and rich in carbohydrate and fat. Despite these different predisposing factors, death from ischemic heart disease is 3-6 times less frequent than in Denmark. The serum calcium/magnesium ratio in Greenlanders is significantly lower than in Danes. Magnesium deficits in patients with acute myocardial infarction, as well as epidemiologically positive correlations between dietary calcium/magnesium ratios and ischemic heart death, are the basis for attributing the low incidence of ischemic heart death in Greenland to the low Greenlandic calcium/magnesium ratio in diet and blood serum. Other characteristics of the Greenlandic disease pattern include a low incidence of stones in kidney and urinary tract, few cases of diabetes mellitus, prolonged bleeding time, increased atrioventricular block and osteoporosis, all of which may also be related to a low calcium and high magnesium metabolic status.

Purified osteocalcin from cow and calf bone was analyzed for nonenzymatic glycosylation (glycation) by sodium [3H]borohydride reduction. Calf bone was found to be approximately 5% glycated, while bone from mature cows was 10% glycated. These results were confirmed by a second method which utilizes periodate oxidation followed by formaldehyde fluorescence. Osteocalcin in human bone was also found to be glycated. The content of glycated osteocalcin from the bones of 47 nondiabetic individuals, aged 0.6-97, was dependent upon age. The extent of glycation was lowest in children, was constant through the adult years, and increased linearly in bone taken from individuals aged 60-97. Glycated osteocalcin was purified by boronate affinity chromatography and subjected to one-step Edman degradation. It was established that the site of glycation was the amino-terminal tyrosine. Increases in the amount of glycated osteocalcin in the bones of older individuals may play a role in the pathogenesis of senile osteoporosis and in the osteopenia which may accompany diabetes mellitus.

As a result of decreases in maternal mortality and infectious diseases, women's life expectancy has increased rapidly in this century and is expected to reach 83 years by the year 2000. However, there are a large number of chronic conditions that negatively affect the quality of life of women today: urinary tract infection, menstrual cycle disorders, hypertension, diabetes, osteoporosis, arthritis, eating disorders, substance abuse, and mental depression. Although women's life expectancy is 7.5 years greater than that of men, the morbidity rates are significantly higher for women. As women continue to enter the labor force in large numbers, questions are being raised regarding the physical and psychological hazards of jobs traditionally considered to be women's work, the risks associated with jobs that are physically demanding or involve exposure to toxic substances, and the association between pregnancy outcome and employment. Further research is needed on the effects of multiple role stress on women's health. Another recent trend has been the feminization of poverty: 2/3 of all US adults classified as poor are women. The lack of financial resources has a detrimental effect on nutrition, access to health care, and other preventive behaviors. Yet another social change related to women's health is the increasing number of elderly in the population. Women comprise 72% of the elderly poor, and over 80% of all retiring female workers do not have pension benefits. Access to, availability of, and payment for health care are problems for elderly women. It is important that research address the physiologic, psychosocial, and economic factors that together affect women's health status.

The study of hormonal alterations due to exercise is of growing interest because of the implications for adaptation, performance, and health. The influence of the sympathoadrenal response on energy metabolism and fluid and electrolyte balance has been of primary interest in past research. Interpretation of results, however, is difficult because of the numerous factors which need to be controlled. Limitations in the interpretation of hormone levels exist because of changes in plasma volume and/or clearance rate and the influences of timing and method of blood sampling. Other factors which must be considered are the design of exercise protocols, and various subject characteristics (sex, age, fitness level, training history, diet, emotional status, diurnal and menstrual variations). Hormonal alterations during acute exercise occur primarily because of sympathoadrenal secretion of the catecholamines which initiate mobilisation of glucose and free fatty acids. This response, in turn, stimulates other endocrine glands and cells (anterior and posterior pituitary, adrenal cortex, thyroid, parathyroid, liver, pancreas, kidney) to secrete secondary hormones which potentiate fuel mobilisation and regulate water and electrolyte concentrations. As duration of exercise increases, nutrient and ion concentrations also influence hormonal responses. In recent years, research has focused on the effect of exercise-induced hormonal alterations on reproductive functioning and various endocrine-related diseases (hypopituitarism, diabetes, osteoporosis, cardiovascular disease). These topics, as well as a better understanding of mechanisms of action via receptor activity, influences on training adaptations, and implications (if any) of hormonal alterations for the growth and development of children, provide challenges for future research.
