The treatment of obesity is one of the major measures available today in the field of preventive medicine. In particular, the coronary epidemic of Western civilisation would be halted, and most cases of maturity-onset diabetes prevented, if obesity were to be treated effectively. Anorectic drugs act mainly on the satiety centre in the hypothalamus to produce anorexia. They also have various metabolic effects involving fat and carbohydrate metabolism, but many of these may be secondary to loss of weight. Most of the drugs are related directly or indirectly to amphetamine and in addition act by increasing general physical activity. Anorectic drugs tend to lose their effect after some months, and part of this reduction in effect may be due to chemical alterations produced by the drugs in the brain. All the drugs, with the exception of fenfluramine, have a stimulant effect on the central nervous system in some individuals, resulting in restlessness and nervousness, irritability and insomnia. Fenfluramine commonly produces drowsiness in normal doses, but has stimulant effects with overdosage. Dexamphetamine, phenmetrazine and benzphetamine all tend to cause euphoria and the risk of addiction is therefore considerable. Euphoria occasionally occurs with diethylpropion, phentermine and chlorphentermine, but to a much lesser extent. Side-effects also occur due to sympathetic stimulation and gastro-intestinal irritation. These side-effects may cause some individuals to stop taking the drug, but are never serious or dangerous. Drug interactions may occur with monoamine oxidase inhibitors and to a clinically unimportant extent, with antihypertensive drugs. The anorectic drugs have a very definite part to play in the treatment of obesity, mainly for those individuals who have altered their eating habits but have come to a plateau of weight which they find difficult to get below. The drugs are best given in a long-acting form and can safely be continued as long as weight loss persists, provided that the clinician exercises careful supervision. Dexamphetamine, phenmetrazine and benzphetamine should rarely be used because of the danger of addiction, and chlorphentermine is potentially hazardous for long-term use. Diethylpropion emerges as the drug of first choice, as fenfluramine has a tendency to cause depression and has a higher incidence of side-effects. Fenfluramine is mainly useful for people who are especially tense and for obese maturity-onset diabetics who have been unable to lose weight with the biguanides. Mazindol and phentermine appear to be useful as alternative drugs.

Two patients with insulin-dependent diabetes mellitus (IDDM) for 42 and 46 years respectively were diagnosed to produce factitious hypoglycemia. They had several properties in common: abnormal personality, refusal to stop incipient hypoglycemia, ideal body weight, good hemoglobin A1c (HbA1c) values, non-specific changes in the EEG, and brain atrophy sparing the periventricular areas. The addiction forced the patients to continue their habit during hospital stay. The dose of surreptitiously injected regular insulin always produced serum insulin concentrations large enough to clarify the diagnosis.

To study the urban-suburban differences in low birthweight among black Americans, 54,870 single births occurring to black mothers in the hospitals of Washington, DC, from 1980 to 1984 were analyzed. The observed data showed a 25% higher incidence of low birthweight (under 2501 gm) among infants born to urban mothers compared with those born to suburban mothers. Bivariate analysis showed that a greater proportion of urban mothers, compared with the proportion of suburban mothers, was teenage (23.6% vs 10.3%) and unmarried (67.6% vs 32.9%), had less than a high school education (31.7% vs 9.1%), and received inadequate prenatal care (34.3% vs 20.3%). The logit model fit to these data showed that by controlling for the above risk factors, the residential differences in the incidence of low birth rate were almost eliminated. Exploration of the medical risks associated with adverse pregnancy outcomes showed that the urban mothers had substantially higher rates for premature rupture of membrane, concurrent hypertension, pre-existing diabetes, hyperemesis, anemia, and narcotic addiction. The findings of the article underline the usefulness of studying intra-black differences rather than relying solely on race comparative research.

Since the isolation of enkephalins 7 yr ago, there has been an explosive increase in knowledge and an enormous interest in the action of both exogenous and endogenous opiates. This review deals with the interaction of opiates with the endocrine pancreas. The results of animal studies performed in vitro do not allow any conclusion to be drawn, because the effects of opioid peptides on pancreatic hormone release seem dependent on many variables, including the agent investigated, dose administered, concentration of glucose in the medium, and experimental procedure used. The results of in vivo animal studies suggest that central administration of opiates and opioid peptides acts indirectly via the sympathetic nervous system to cause hyperglycemia and impaired insulin secretion, while peripheral administration tends to stimulate insulin and glucagon secretion. This last statement seems also to be true for studies performed in human beings. The narcotic addict offers a model to evaluate the hormonal and metabolic effects of a chronically administered agent that binds and activates endogenous receptors. In these subjects, it is possible to find increased concentrations of glycosylated hemoglobin A1 and a marked reduction of the acute insulin response to intravenous glucose, but not to arginine, which suggests a state of defective glucose recognition by pancreatic beta-cells during narcotic addiction. Thus, the heroin addict, like patients with non-insulin-dependent diabetes, does not respond appropriately to glucose signals.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January and December 1992 an epidemiological survey on the risk factors for cardiovascular disease in eighteen-year old boys during call-up has been performed in Verona. The study involved 3426 subjects: 100% of the boys coming from the metropolitan area and 65% of those coming from the non-metropolitan areas. A family history of hypertension was found in 9.54% of the subjects and a family history of myocardial infarction or sudden death was found in 4.54% of the subjects. 0.18% of the population reported diabetes and 2% hypertension. Prevalence of smoke addiction was 39.1% and in this group 17.54% smoked > or = 20 cigarettes/day. Prevalence of smoke addiction was significantly greater in the boys having one or both smoking parents (p < 0.001), in working people in respect to students (p < 0.001), in boys from metropolitan in respect to those from non-metropolitan areas (p = 0.033), and among those not practising sport activity (p < 0.001). Mean systolic and diastolic blood pressure were 130.16 +/- 13/74.48 +/- 9 mm Hg and 90th percentile was 149/87 mm Hg. Systolic and diastolic blood pressure were significantly lower in boys from metropolitan in respect to those from non-metropolitan areas and in smokers in respect to non smokers. A body mass index > or = 30 was found in 3.04% of the subjects, the body mass index being directly related to systolic and diastolic blood pressure (p < 0.001). Total cholesterol performed on a voluntary basis from capillary blood samples by Reflotron System was determined in 80.06% of the subjects. Mean blood cholesterol was 139.1 +/- 28 mg/dL and 90th percentile's value was 182 mg/dL. Mean blood cholesterol was significantly lower in non-metropolitan in respect to metropolitan areas (p = 0.033). 44.48% of the subjects had one or more risk factors, 5.22% had two risk factors and 0.67% three or more risk factors for cardiovascular disease. This study shows that 1) in this population of young people a significant part is exposed to one or more cardiovascular risk factors; 2) social and environmental factors affect, sometimes deeply, the prevalence of cardiovascular risk factors; 3) The visit for call-up appears to be important in the setting-up of a strategy of primary prevention for cardiovascular disease.

Results of morbidity and medical care surveys of the Santiago's population are presented in this paper. A random sample of 1,000 dwellings with 4,700 people was selected and studied 3 times, in 1993 and 1994. All health events (acute and chronic morbidity, health examinations, dental care) and main features of medical care were registered in the interviews which covered a 2-week period each time. The population sample had similar characteristics than the results of the last Population and Dwellings Chilean Census. Health events were registered with high frequency: 56% of the families had one or more members with chronic disease; 51% with acute diseases; 46% with emotional troubles; 24% had dental care; 17% health examination and 6% different types of injuries. Frequency of medical care during the fortnight period was 5.6% out of total population of acute diseases; 1.0% of injuries; 4.9% for chronic diseases, 3.9% of health examinations and 5.6% of dental care. Frequency of diseases was significantly higher among women (50%) than in men (33%) and in poor people than in higher socioeconomic levels. Most of the acute disease were respiratory illnesses followed by communicable diseases, skin troubles and rheumatologic disorders. The most important detected chronic diseases were blood hypertension, diabetes mellitus, bronchial asthma and alcoholic addiction.(ABSTRACT TRUNCATED AT 250 WORDS)

Short-term outcome after coronary angioplasty is mainly determined by restenosis, while long-term outcome is determined by new events due to incomplete revascularization, by atherosclerosis progression and by late-restenosis. The aim of this study is to assess if correctly treated coronary risk factors are predictors of poor prognosis after coronary angioplasty. Two-hundred and twenty six patients (209 males, 17 females, mean age 56 +/- 9 years) with successful coronary angioplasty were treated for coronary risk factors. New events (death, myocardial infarction, repeat angioplasty, bypass surgery) were recorded. Ischemia was evaluated by serial exercise tests. The mean follow-up was 31 +/- 12 months. Survival was 99.5% at 1 year and 97.4% after 5 years; "event free survival" was 84.6% at 1 year and 65.9% after 5 years; "ischemia free survival" was 84.6% at 1 year and 44.8% after 5 years. "Ischemia free survival" was higher in patients with single coronary angioplasty and in patients with infarct-related vessel angioplasty. Smoke addiction, diabetes, hypercholesterolemia and hypertension were not significantly correlated with "ischemia free survival". Smokers and diabetics had a trend towards a less favorable 5 year outcome, but without statistical differences. In conclusion, this study shows that correctly treated coronary risk factors do not worsen prognosis after coronary angioplasty.

The study, conducted over 4 years among 400 diabetic patients, reports the epidemiological and clinical aspects of diabetes mellitus at the National Hospital of Ouagadougou, Burkina Faso. Epidemiologically, diabetes mellitus affects men by 64% and women by 36%. 76% are over 40 y. o., whereas only 2.2% are under 20. Clinically, the classification of diabetic patients shows that 10.7% are insulin-dependent and 76.5% non insulin-dependent. No usual tropical diabetes has been found. The calcifications observed in 2.5% of cases were combined with chronic alcoholic pancreatitis. The classic triad (polyuria, polyphagia, polydipsia) led to diagnostic by 41% of the patients, whereas 27.5% have been identified when having complications, and 23% by a systematic check-up. Cardio-vascular risk factors combined with diabetes have been found: obesity (28%), high blood pressure (20%), hyperuricaemia (14%), addiction to smoking (20%). The epidemiological characteristics, as well as the various clinical aspects, mostly complies with the observations of the african authors.

Female albino rats were exposed to methadone over a 35-day period by addition of the drug in their drinking water. The final dose of the drug was 1.8 mg/kg body weight per day. After this period, the drug was withdrawn from some animals for 30 days (postexposure). Compared to unexposed controls, serum glucose levels rose during exposure and returned to control levels postexposure. Oral glucose tolerance tests showed impairment in 35-day drug-exposed animals compared to controls and postexposure. The activities of three key enzymes of glycolysis and three key enzymes of gluconeogenesis were measured in liver during and at the end of the exposure period, as well as postexposure. Compared to unexposed controls and postexposure, specific activities of two glycolytic enzymes in livers of exposed animals-hexokinase and phosphofructokinase 1-were significantly reduced, whereas the activity of a third glycolytic enzyme-pyruvate kinase-was unchanged. The specific activities of two gluconeogenic enzymes-glucose-6-phosphatase and fructose-1,6-biphosphatase-were significantly elevated in the drug-exposed animals compared to controls, whereas the activity of a third enzyme-phosphoenolpyruvate carboxykinase-was unchanged. These data indicate that methadone addiction produces a metabolic state similar to insulin-resistant diabetes.

Concerns about high costs have led to limits on the services covered by most insurance plans for substance abuse treatment. But, the commonly used comparison group for cost analyses, all enrollees in a health-care plan, may not be appropriate because addiction is a chronic condition. Therefore, to determine whether substance abusers incur higher charges than patients with other serious chronic conditions, we used health insurance information for employees and dependents over 3 years (1989 to 1991) for two firms with a total of almost 40,000 employees to do alternate comparisons. We compared average annual charges for patients with the following diagnoses: substance abuse, substance abuse with mental illness, arthritis, asthma, and diabetes. Patients who undergo treatment for abusing alcohol, drugs, or both often (but not always) incur higher charges than people with other chronic conditions. Clear differences in average charges emerge between patients with and without mental health claims.
