The object of the present research was to study the effect of dexfenfluramine (d-F) and placebo (P) on compliance with dietary treatment, especially as far as changes in kcal and macronutrient intake are concerned. A double-blind study d-F vs P was performed in 36 obese females, age range 20-59 years (mean 37.22 +/- 12.41), with a mean BMI of 33.95 +/- 5.36, suffering from obesity due to overeating without complications: Outpatient control every 30 days. The study protocol provided for a 14-month double-blind treatment with daily administration of either P (2 capsules) or d-F (two 15 mg capsules). Dietary prescription of 1200 kcal (5016 kJ) was given 15 days before enrollment (T/0) and during this period enrollment criteria were checked prior to randomization. Dietary intake was checked by a three-day recall (one working day, one half-holiday and one full holiday) in basal conditions and after 6-12 and 14 months. Administration of d-F and P brought about changes in alimentary behaviour in obese patients according to the dietary regime prescribed. In our patients, no highly significant differences between d-F and P were observed; however, the effect of P on macronutrient intake (carbohydrates, lipids and proteins) tended to peter out around the 12th month. Treatment with d-F reduced the consumption of simple carbohydrates, animal fats but not of animal proteins.

One hundred and twenty-six patients with radiolucent gallstones in 'functioning' gallbladders were treated with 8-10 mg ursodeoxycholic acid (UDCA) kg/day and followed to a treatment conclusion. Complete or partial gallstone dissolution was achieved in 74 (59 per cent). However, only 22 achieved complete gallstone dissolution, as judged by two normal oral cholecystograms; ultrasonograms were performed in 16 of these patients, and all were normal. UDCA was stopped in 76 patients: because of cystic duct obstruction (n = 12), severe biliary pain (n = 13), non-response (n = 25) or partial stone dissolution with arrested progress (n = 26). Life-table analysis showed that complete gallstone dissolution rates at four years were 25-30 per cent (two normal oral cholecystograms) and 17-19 per cent (two normal oral cholecystograms plus one ultrasonogram). All patients with complete gallstone dissolution had shown partial stone dissolution at 6-12 months; of those with partial stone dissolution at six months, only 25 per cent went on to complete gallstone dissolution, and then always within two years. Efficacy correlated inversely with stone size but not with age, sex, obesity or on-treatment saturation indices. Acquired surface gallstone calcification developed in 13 patients (life-table analysis 22 +/- 7 per cent at four years); none of these patients achieved complete gallstone dissolution and only five achieved partial stone dissolution. Thus, despite relatively high partial gallstone dissolution rates, the ultimate efficacy of UDCA in achieving complete gallstone dissolution is low.

More than 10 controlled epidemiologic studies are reported and reviewed in this paper which examine gallbladder disease and oral contraceptive (OC) use. Findings concerning an association between the 2 are contradictory. OC use and the use of estrogens in postmenopausal women have been reported to be associated with increased attack rates of gallbladder disease, but the increased risk in higher in those women using estrogens than progestin-based OCs. Other studies, however, have reported little overall effect of OC use on the development of gallbladder disease. Where increased risk has been documented, it has been related more to duration. The increased risk of gallbladder disease related to OC use has been observed to be higher within the 6-12 month range of usage. Only 1 study reported increased risk of gallbladder disease in longterm users. The increase may be greater in multiparae than nulliparae; pregnancy and obesity may also pose an increased risk to the disease in OC users. However, these findings are not widely accepted.

Glucose tolerance and insulin secretion were studied in 56 women 6-12 years following a pregnancy complicated by gestational diabetes, and in 23 matched controls. At recall 14 women were known to have diabetes and five were again pregnant with recurrent gestational diabetes. The early development of diabetes was associated with a fasting plasma glucose greater than 6 mmol/l during pregnancy and with a high plasma glucose response to oral glucose which persisted after delivery. Obesity was predictive of non-insulin-dependent diabetes whereas those that later required insulin were not obese. At recall, seven of the remaining 37 women were found to have unrecognized diabetes, 13 had impaired glucose tolerance (IGT) and 17 were normal by WHO criteria using a 75 g oral glucose tolerance test. In these 37 women, fasting plasma glucose and the glucose response to oral glucose in pregnancy were not predictive of subsequent diabetes or impaired glucose tolerance. Obesity in pregnancy and subsequent weight gain were associated with non-insulin-dependent diabetes and impaired glucose tolerance at recall. Insulin deficiency was observed during the oral glucose tolerance test in the diabetics (the mean +/- SEM ratio insulin area:glucose area 4.1 +/- 1.3 diabetics, 10.7 +/- 1.8 controls, p less than 0.05), whereas in the group with impaired glucose tolerance insulin levels were high and in proportion to their hyperglycaemia (insulin area:glucose area 10.9 +/- 1.4 IGT, 9.4 +/- 1.4 controls). Women with normal glucose tolerance and previous gestational diabetes had significantly lower insulin responses than their controls, despite mild hyperglycaemia (insulin area:glucose area 4.0 +/- 0.7 normal glucose tolerance, 7.6 +/- 1.1 controls, p less than 0.02). Abnormalities of glucose tolerance and insulin secretion are present following a gestational diabetic pregnancy. Gestational diabetes identifies women at risk for developing diabetes and impaired glucose tolerance, both of which are risk factors for premature vascular disease.

In sarcoidosis and other granulomatous non-caseous diseases, the election treatment is immunosuppressive, mainly with cortisones that ensure more than 70% lasting remissions. Continuous use of cortisones for a long time (8-30 months) in high doses leads to serious side effects: gastric and intestinal ulcers, obesity, osteoporosis, suprarenal dysfunction, sensitivity to infections. Good results and elimination of the important side effects were obtained by treatment with Reprimum--a semisynthetic antibiotic with a wide spectrum and immunosuppressive properties--administered alone or with prednisone in small doses (15-20 mg once) in 6 weeks' series: 2 weeks--Reprimum 10/mg/kg daily +/- prednisone and for other 4 weeks--Reprimum 15 mg/kg twice a week +/- prednisone followed by two weeks' break. In 75 patients with histopathologically confirmed sarcoidosis (of whom 7-9.3% with outside-the-lung situs, too), the treatment with Reprimum gave: 94.7% lasting remission, only 5.3% failures, reduction of the treatment period to 6-12 months and the absence of any important side reaction. In other 37 sarcoidosis cases, failures of cortisone therapy (of which 11-30% relapses after 2-6 years), the treatment with Reprimum together with prednisone allowed recovery of 29 patients (78.4%). The same treatment with Reprimum, used in 22 patients with immunosuppressive treatment indication (dermatomyositis, Kaposi's syndrome, thrombocytopenias, nodose periarteritis, silicosis), of whom 18 (81.8%) were failures of the cortisone therapy, healed 20 of these cases (90.9%). Reprimum immunosuppressive property acts at the level of T4+ lymphocyte, involved in sarcoidosis pathogenesis. The functional blockage of T4+ lymphocyte can be also achieved by cyclosporine A.(ABSTRACT TRUNCATED AT 250 WORDS)

We have recently shown that in addition to beta-endorphin the opioid peptides Met- and Leu-enkephalin and their apparent precursors are localized in islet endocrine cells of the rat pancreas. To begin evaluating a possible role for these pancreatic opiates in the pathophysiology of genetic diabetes in rodents, immunoreactive beta-endorphin and Met- and Leu-enkephalins were measured in acetic acid extracts of pancreas and pituitary of C57BL/KsJ db/db mice and their lean littermates. Groups of animals were studied during three phases of development of the diabetic syndrome in the mutant mice: at 4 (hyperinsulinemic and prediabetic); 6, 9, and 12 (frankly obese and diabetic); and 30 (hypoinsulinemic) wk of age. Elevations or decreases (P less than .05) were found in db/db mice (vs. lean littermates) as follows: pituitary content of Met-enkephalin was twofold higher at all ages studied; pituitary free Leu-enkephalin was lower at 4 wk and reversed to higher at 6-30 wk; pancreatic beta-endorphin was 30% lower at 4 wk and reversed to threefold higher at 6-12 wk; Met- and Leu-enkephalin-containing larger peptides were elevated at one or more points between 6 and 12 wk in both the pancreas and the pituitary. Thus, the onset of overt obesity between 4 and 6 wk of age was accompanied by a marked rise in both pancreatic beta-endorphin and pituitary Leu-enkephalin; similar elevations in these parameters have been reported previously in C57BL/6J ob/ob mice at approximately 12 wk of age.(ABSTRACT TRUNCATED AT 250 WORDS)

In a Finnish Multicentre Study, height, weight and skinfold thicknesses were measured in 3-, 6-, 9-, 12-, 15-, and 18-year-old children (N = 3,596). Height and weight percentiles superimposed on the current Finnish growth charts were above the standards in 6-15-year-old boys and 3-12-year-old girls. Triceps skinfold thickness percentiles (10% and 90%) appeared to be closest to British values and below American values. Weight, body mass index (BMI) and skinfold thicknesses showed good intercorrelations (up to .90) except in young boys. Height had a low positive correlation with BMI (.28 to .36) and with skinfold thickness (.23 to .36) in the age groups 6-12 years. BMI and subscapular skinfold seem to be useful obesity indicators. No consistent correlations were seen between physical variables and serum LDL- or total cholesterol and apoprotein B concentrations. There was a slight negative correlation between the physical variables and serum HDL-cholesterol. Apoprotein A1 correlated negatively to all obesity indicators in 12-year-old girls. Serum triglycerides showed slight positive correlation to physical variables. BMI and skinfolds had a low to moderate correlation with insulin (.21-.51) mainly in the three oldest age groups. On the ground of BMI and skinfold measurements we have reason to believe that the prevalence of obesity at 3-18 years of age is similar in Finland as in other countries in Europe.

Incisional herniation remains a major problem for the general surgeon. Most published studies have followed up patients for 6-12 months after operation. In this study, 363 patients, known not to have an incisional hernia at 1 year, were reviewed between 2.5 and 5.5 years after operation. Twenty-one patients (5.8 per cent) were found to have developed incisional hernias. None of the causal factors previously implicated in the aetiology of incisional herniation (wound infection, male sex, obesity, age, postoperative chest infection or abdominal distension), was found to be associated with the development of these 'late hernias'.

To test whether the property of medium-chain fatty acids (which have 6-12 carbon atoms) being incorporated only in small amounts into the various tissues of a living organism could be exploited to treat obesity, genetically obese Zucker rats and their lean littermates were fed a diet containing 20% medium-chain triacylglycerols (MCT) or long-chain triacylglycerols (LCT) for 10 weeks. MCT, as compared with LCT, had the following effects: 1) MCT did not diminish weight gain in either the nonobese or the obese rats; 2) they increased ketogenesis more in the former than in the latter; 3) they increased the concentration of triacylglycerols in the liver of the obese rats but not of the lean ones; 4) they decreased the concentration of cholesterol in the liver of the lean but not of the obese rats, and 5) they did not particularly affect the concentration of proteins, glucose and insulin in the blood. We therefore conclude that the influence of the genotype is much more important in the establishment of the biochemical characteristics of rats than is the nature of the fatty acids ingested. Replacing LCT in the diet with MCT did not correct any of the major metabolic disorders in obese rats and therefore cannot unaided constitute a solution to the problem of genetic obesity.

Childhood obesity is an increasing problem in developed countries. Its persistence into adulthood with accompanied health risks has raised many concerns. In a country with rapid growing economy and changing life styles such as Thailand, the natural history of obesity in school children aged 6-12 years was investigated. Yearly weight and height measurements were performed from 1991 onwards. Of 1,156 primary school children enrolled in 1991, two year follow-up was possible in 1,106 cases. Prevalence of obesity, as diagnosed by weight-for-height > 120% of the Bangkok reference, rose from 12.2% in 1991 to 13.5% in 1992 and 15.6% in 1993. In two years, 74 non-obese children became obese while 28 obese children showed the opposite trend. For those obese children who attended the weight control program, their body mass indices and triceps skinfold thickness increased significantly less than those of the non-attendees in the first year. These findings persisted in the second year but were of a smaller magnitude. Results of this study demonstrate the trend of increasing obesity in school children in the transitional society and the short term benefit of a weight control program.
