After a control period on a placebo, 45 patients with mild to moderate hypertension were treated with metoprolol, 100 mg twice daily alone and in free combination with chlorthalidone 50 mg daily using a double-blind crossover technique. The beta-blocker alone induced a significant fall in blood pressure; the diastolic pressure was reduced to 100 mg Hg or less in 37 of the 45 patients and to 95 mm Hg or less in 19 patients. The addition of chlorthalidone enhanced the antihypertensive effect so that in 33 patients diastolic pressure fell to 95 mm Hg or less. The drugs were well tolerated even by a small number of patients with chronic bronchitis and diabetes mellitus. None of the patients developed cardiac failure. Adding a diuretic caused a small reduction in serum potassium concentrations, and the relevance of this observation is discussed.

Obesity, a common disorder causing excess mortality due to the development of cardiovascular disease, hypertension, respiratory illness, and diabetes, is difficult to control by simple dieting techniques. Low calorie foods, which can facilitate newer weight reduction approaches such as behavior modification, often lack adequate palatability due to the absence of carbohydrate or fat. Various low calorie bulking agents that can replace the traditionally used carbohydrates and fats are discussed in terms of caloric value, utility, and regulatory status. Methods of measuring caloric utilization of bulking agents in test animals and humans are evaluated. For fat, no really satisfactory replacement is currently available, although several promising are under development. Dietary fiber sources such as microcrystalline cellulose are receiving considerable attention as flour replacements. While the polyols have many desirable attributes, as sucrose replacements, their caloric utilization values generally prevent a significant caloric reduction when they are used in foods. Several experimental sucrose replacements are described.

Estrogen replacement in menopause should be used for specific symptoms such as ovarian failure, hot flushes, vaginal atrophy, atrophy of the vulva, and atrophic urethritis. The dose should be as low as possible to be effective and perscribed for as short as time as possible, since there are possible risks of uterine cancer, breast cancer, increased blood pressure, gallstones, deep vein thrombosis, and thromboembolism. Estrogens should be administered to provide the maximum benefit with the minimum risk involved. Estrogens should not be given to patients with known contraindications such as: suspected breast or uterine cancer; undiagnosed genital bleeding; Dubin-Johnson syndrome; acute hepatic disease; previous or present thromboembolism; or severe thrombophlebitis. Careful evaluation should be made before administering estrogen to women with uterine myomata, hyperlipidemia, hypercholesterolemia, sevare varicose veins, chronic hepatic dysfunction, diabetes mellitus, porphyria, or severe hypertension.

At the Gynecological University Hospital in Marburg/Lahn, 190 women with cancer of the ovary who had been under clinical treatment from 1962--July 1976 were studied epidemiologically. Special risk factors which seem to predispose to the development of cancer of the ovary were determined. Higher social standing, having no children or having born more than four children, a shortened menarche-menopause interval, having had radiation of the pelvis, as well as having had an appendectomy seem to be factors overrepresented among cancer patients in Marburg. More patients had blood group A and fewer had blood group O than would be expected from the distribution in the population as a whole. Polyps of the corpus uteri were often seen to precede cancer of the ovary. Diabetes mellitus, adiposity, hypertension and varicosis were frequent accompanying diseases. Many patients had a fmily history of cancer.

Using ultrasonic A- and B-scan equipment (Kretz-Technik), 80 pregnancies with chronic placental dysfunction were investigated: 34 cases with hypertension, 24 cases with diabetes and 22 cases with rhesus immunization. In addition to biparietal diameter (A-scan), the direct and transverse diameter, the circumference and the area were estimated on B-scan displays of the occipito-frontal plane and the largest cross-sectional plane of the abdomen. 15 parameters of fetal growth and body composition were compared with normal standards. The significance of the different methods in the diagnosis of fetal dysmaturity was demonstrated.

Simultaneous determinations of unconjugated estriol and 15alpha-hydroxyestriol (E4) levels in maternal serum were studied serially to ascertain the relative usefulness of these estrogens as indicators of fetal welfare. Complicated pregnancies included 16 patients with pre-eclampsia and/or hypertension, six patients with severe Rh-isoimmunization, 12 patients with diabetes mellitus, of which four had vascular disease, three patients with fetal death in utero, and three twin pregnancies. Retrospective analysis failed to indicate a clinically useful role for serum E4 determinations in the evaluation of fetal welfare during high-risk pregnancies.

Radiographs of 175 patients with diffuse idiopathic skeletal hyperostosis (DISH) of the spine or ankylosing spondylitis were reviewed. DISH most frequently began in the middle and lower portions of the thoracic spine; it was rare in the upper portion. A few vertebrae were first affected, and then involvement extended, sometimes throughout the thoracic spine. The anterior and lateral aspects of vertebral bodies were mainly affected. Hyperostosis vertically spanning the anterior aspects of the vertebrae varied in thickness up to 10 mm, and the rate at which the hyperostosis proliferated was not specific for any vertebra. Males were 12 times more frequently affected than females, especially in the older age groups. Diabetes mellitus and hypertension have reportedly been associated with DISH, but no such correlation was found in this study. Despite the existence of criteria for differential diagnosis, it is sometimes difficult to distinguish ankylosing spondylitis from DISH radiologically. The radiologic features helpful in the differential diagnosis are described, and a review of the pertinent literature is included.

Long-term dialysis treatment of diabetics with terminal renal failure is beset with severe complications. In 19 unselected diabetics in terminal renal failure (13 juvenile diabetics and 6 maturity-onset diabetics) the clinical course during long-term dialysis was observed. A total of 1377 dialyses during 167 months of treatment were performed. Diabetic angiopathy, hypertension, and hyperhydration were the most prominent complications. The interval between the onset of diabetes and the beginning of dialysis treatment was 21,5 years in the juvenile diabetics and 5,2 years in maturity-onset diabetes. The survival time during dialysis was on average 13,2 months for the juvenile diabetics and 0,6 months for maturity-onset diabetics. The patients died chiefly from cardiovascular complications.

In 240 patients with peripheral circulatory disorders (Fontaine Stage II) who had participated in intensive physiotherapeutic interval training daily for 6 weeks between October 1974 and July 1976, it was established that the therapeutic results were not related to age or sex. The "risk" factors of smoking, diabetes mellitus, hypertriglyceridemia, hypercholesterolemia and hyperuricemia individually show no connection with the results. Only overweight, hypertension and coronary heart disease appear to have an unfavorable influence. It is distinctly recognizable that the more risk factors there are combined in a patient with intermittent claudication, the less chance he has of success in physiotherapeutic vessel training.

Human body continuously assimilates a variety of elements from the environment and the concentration of these elements in blood is regulated by means of various homeostatic mechanisms. Some of the elements, though present in very small amounts perform highly specialized functions in initiating many biochemical reactions. These elements, known as essential trace elements, are closely related to human diseases as their deficiency or excess induces physiological changes. Many diseases such as hypertension, atherosclerosis, diabetes etc are related to trace element imbalance. Therefore the measurement of trace elements in body fluids and tissues can be effectively employed for diagnostic tests.
