Intussusception of the defunctionalized intestinal segment following jejuno-ileal bypass for obesity has rarely been reported. Persistent crampy abdominal pain (often accompanied by nausea and vomiting) and normal radiologic evaluation are suggestive of this entity. The routine use of silver clips, although helpful in some instances, cannot exclude this diagnosis. A high index of suspicion and the use of sonography may prove that intussusception of the defunctionalized segment is more common than has been previously reported.

The effect of one of the new human pancreatic growth hormone releasing factors (hpGRFs) was assessed in children or young adults with different forms of growth retardation or endocrine-metabolic diseases. Intravenously administered synthetic hpGRF-40 (1 microgram/kg) induced a clear-cut and prompt rise in plasma growth hormone (GH) levels in 8 normal prepubertal children and a definite GH rise in 11 out of 14 children with isolated GH deficiency (IGHD) and one child with the Silver-Russel syndrome. In two out of three subjects with craniopharyngioma hpGRF-40 did not induce any plasma GH increase. In seven out of ten children with constitutional growth delay (CGD), hpGRF-40 induced a biphasic GH response, with a prompt small GH increment followed by a second, more consistent rise. Both in children with IGHD and with CGD the rise in plasma GH following hpGRF-40 was markedly lower than in controls. In children with CGD the GH response to hpGRF-40 was defective, despite the fact that in most of them the GH response to standard pharmacological stimuli was normal according to generally accepted criteria. hpGRF induced a small but sustained plasma GH rise in four hypothyroid subjects, while in three out of four children with idiopathic obesity the GH response to hpGRF was strikingly reduced. These data demonstrate that hpGRF is a potent stimulus of GH release in normal prepubertal children and a physiological means of investigating GH function in diseases associated with growth impairment.

About 50 mg of silver leaf (metallic silver) was given daily by mouth to 30 healthy volunteers for 20 days. A statistically significant hypophospholipidemic, hypotriglyceridemic, hypocholesterolemic and hypoglycemic effect was observed. This was accompanied by a less marked fall in total lipids and significant rise in HDL-cholesterol. In addition, a decrease in plasma enzymes - alkaline phosphatase (ALP), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), creatine phosphokinase (CPK), gamma glutamyl transpeptidase (GGT) and lactate dehydrogenase (LDH) was noted. This was statistically significant for all enzymes except CPK. The safety of ingested silver foil is indicated by absence of pathology in urine and unaltered levels of protein and albumin in the plasma. These observations suggest that silver could be beneficial in conditions like diabetes mellitus, obesity and atherosclerosis.

Severe obstructive sleep apnea (OSAS) is most often accompanied by metabolic syndrome, obesity, diabetes and coronary disease. In its most severe form, it is a life-threatening condition, requiring active and immediate help. Nasal continuous positive airway pressure (CPAP) is the most efficient nonsurgical treatment for patients with OSAS. However, for anatomical, disease-related and subjective reasons, many patients cannot accept this treatment. A permanent tracheostomy may be one alternative in such patients who, in addition, often suffer from extreme obesity and severe heart disease. In this paper, we describe the long-term follow-up results of 7 patients suffering from OSAS and treated with permanent tracheostomy. All the patients (5 men, 2 women) were diagnosed using the static charge sensitive bed method and night-time oximetry for sleep analysis. The mean body mass index (BMI) of the patients ranged from 34 to 60 and the age from 41 to 64 years. All the patients had severe OSAS and long periods of low oxygen saturation (SaO2) levels. Six patients had a CPAP trial before tracheostomy. Only 2 patients tolerated the trial but, despite the continuous use of CPAP, they were nonresponders. Permanent tracheostomy was done according to normal routine in each patient. After primary healing of 2 days, they used silver cannulae, which also allowed them to speak. The patients were evaluated every year after the tracheostomy. After some practical difficulties including proper maintenance of the cannula, all the patients quickly learned the correct management. In postoperative sleep studies, nadir SaO2 levels had improved significantly, obstructive apneas had disappeared and the subjective quality of life had improved. No marked changes in BMI were found.

Small lesions centered in the posterodorsal region of the medial amygdala resulted in excessive weight gains in female rats. Unilateral lesions were nearly as effective as bilateral lesions in the first 48 h after surgery (+21 to +32 g). Assessment of lesion damage was done by both qualitative evaluation and by a quantitative grid-point counting method. The critical sites for weight gain were the intra-amygdaloid bed nucleus of the stria terminalis and the posterodorsal medial amygdaloid nucleus. Incidental damage to the overlying globus pallidus was negatively related to weight gain. The cupric silver method for demonstrating axonal degeneration was applied to brains with obesity-inducing lesions. A dense pattern of degenerating terminals was found in the lateral septum, amygdala, ventral striatum, and ventromedial hypothalamus. Degeneration in the paraventricular nucleus of the hypothalamus was scarce or absent. Small retrograde tracer injections made in either the intra-amygdaloid bed nucleus of the stria terminalis or in the posterodorsal medial amygdaloid nucleus labeled cells in the amygdala, lateral septum, and hypothalamus, reciprocating the anterograde projections from the amygdala to these areas. The data suggest that subdivisions of the posterodorsal amygdala participate in the regulation of feeding in a manner that is similar to the better-known role of this part of the brain in mediating reproductive behavior. Although topographical differences may exist within the amygdaloid and hypothalamic subdivisions regulating these two sexually dimorphic behaviors, the relays engaged by feeding-related connections and those related to reproduction are remarkably parallel.

Homozygosity for the interleukin-6 (IL-6) g.-174G>C promoter polymorphism has recently been associated with indices of overweight. Homozygous subjects were observed to have reduced energy expenditure, suggesting that lower IL-6 gene transcription, caused by the IL-6 g.-174G>C promoter polymorphism, may be associated with obesity. The aim of this study was to investigate the association of this polymorphism with long-term weight gain. For 334 normal weight (20 < BMI < or = 25 kg/m2) and 334 obese (BMI > 30 kg/m2) subjects matched by age and sex originating from the population-based EPIC-Potsdam Study, recalled weight change from age 25 to study enrollment was determined, the IL-6 g.-174G>C promoter polymorphism was defined, and plasma concentrations of IL-6 and C-reactive protein were measured. The IL-6 g.-174G>C promoter polymorphism was significantly associated with obesity (chi2 = 7,34, p = 0.026). Odds ratios for subjects with GC and CC genotypes for obesity were 1.19 (95% CI: 0.84 to 1.68; p = 0.323) and 1.91 (95% CI: 1.19 to 3.08; p = 0.007), respectively. Recalled weight change from age 25 years to study enrollment differed significantly according to genotype (p = 0.044) and was most pronounced in subjects with the CC genotype, suggesting that the IL-6 g.-174G>C promoter polymorphism is a susceptibility or modifying locus for common obesity and weight gain.
