The epidemiology of inguinal hernia was investigated in a community survey in a neighbourhood of western Jerusalem in 1969-71. The current prevalence rate, excluding operated hernias, was 18 per 100 men aged 25 and over, and the lifetime prevalence, including operated hernias, was 24 per 100. Prevalence rose markedly with age; the lifetime prevalence rate reached 40 per 100 men at the ages of 65-74 and 47 per 100 at 75 and over. The prevalence of hernia was significantly higher in the presence of varicose veins, in men who reported symptoms of prostatic hypertrophy, and, among lean men only, in the presence of haemorrhoids. These associations may reflect the role of increased abdominal pressure. The prevalence of hernia was low in the presence of overweight or adiposity, suggesting that
obesity
is a protective factor. No significant age-independent associations were found with chronic cough, constipation, physical activity at work, or a number of other variables. Two-thirds of the hernias had not been operated upon. The prevalence of unrepaired hernias rose with age; 13% of all men aged 65-74 and 23% of those aged 75 and over had unoperated groin swellings. One in every five operated hernias showed evidence of recurrence. No significant age-independent associations were found between evidence of occurrence and other characteristics. A comparison of interview responses and examination findings showed that interview data on the presence of hernias were of low validity, mainly because of under-reporting.

The sera of 160 diabetics who were well controlled by oral hypoglycaemic agents (OHA) for at least three months after diagnosis were tested for pancreatic islet cell antibodies (ICAb) either at diagnosis or within two years after diagnosis. 129 were non-obese at diagnosis and of these ICAb was detected in the sera in 20 (16%). 31 were obese at diagnosis and of these ICAb was detected in the sera in three (10%). All of the 160 diabetics were insulin independent at the time of testing the serum for ICAb. The presence of ICAb was associated with a high probability of becoming insulin dependent, calculated from actuarial statistics. 86% of ICAb positive patients initially controlled on OHA may be expected to be insulin dependent at five years from diagnosis as compared to 18% of ICAb negative patients.
Obesity
at diagnosis did not significantly affect the probability of becoming insulin dependent. ICAb positive diabetes controlled by OHA can be regarded as a less severe form of insulin-dependent (Type I) diabetes.

Three cases of severe anorexia are reported. It results in a strong protein malabsorption with hepatic steatosis and in a syndrome of mental depression which needed the re-establishment of the intestinal-continuity. Although a mild post-operative anorexia is regular and contributes to the weight loss, massive anorexia must be considered as a new and redoubtable unpredictible complication of the surgical treatment for
obesity
, which may hinder the intestinal adaptation and increase the protein malabsorption.

After bypass operation for
obesity
the remaining lactose-hydrolyzing capacity of the functioning shunt is very low, especially if the shunt is constructed from a shorter jejunal and a longer ileal segment. In most cases a temporary decrease in the lactase activity of the jejunal part of the shunt occurs during the first postoperative months. In the present study lactose provoked or aggravated diarrhoea and other symptoms in 20 of 33 shunt-operated patients, and 10 patients reported milk intolerance postoperatively. Oral glucose tolerance tests indicated that the lactase activity was rate limiting for lactose absorption postoperatively.

The present experiments have tested the hypothesis that ventromedial hypothalamic (VMH) lesions enhance insulin secretion by neural mechanisms. Rats were made diabetic by injecting streptozotocin to destroy their own pancreatic beta-cells. Subsequently, transplants of fetal pancreatic tissue were placed under the renal capsule. VMH lesions were placed in rats whose diabetes was cured with transplants as well as sham-transplanted animals. The animals were followed for 4 wk. The lesioned rats with pancreatic transplants gained no more weight than the sham-operated controls. There was no significant rise in insulin in the transplanted rats after VMH lesioning, but the VMH lesioned rats with intact pancreatic tissue showed the expected rise in insulin. Food intake rose 71% in the VMH lesioned rats with intact beta-cells, but only 23% in the VMH lesioned rats with transplants. Hypertrophy of the pancreatic islets was also observed in the VMH lesioned rats with an intact pancreas, but was not found in the VMH lesioned rats with a transplanted pancreas. Thus, transplantation of pancreatic tissue beneath the renal capsule of diabetic rats prevented the characteristic hyperphagia, hyperinsulinemia, and
obesity
in VMH lesioned rats whose pancreas was free from intact innervation. The results support the hypothesis that neural mediation of the rise in insulin is the primary factor in the development of hypothalamic
obesity
.

By employing neutron activation analysis, endogenous content of gold was estimated quantitatively in discrete brain areas and in subcellular fractions of the hypothalamus of gold thioglucose (GTG) induced obese mice. The highest concentration of gold was obtained in the ventromedial hypothalamus (VMH) reaching approximately 100 ng/mg wet tissue. Significantly higher concentrations were observed in other hypothalamic subareas followed by certain limbic areas and the thalamus, while in the cerebral and the cerebellar cortex the gold concentration was very low. Subcellularly, the hypothalamic gold was principally recovered in the supernatant fraction particularly after a hyposmotic shock treatment of the crude mitochondrial fraction. Contrary to GTG, treatment with gold thiomalate (GTM) did not induce
obesity
in the mouse, although considerable amount of gold was observed in the VMH, a finding suggesting the existence in the VMH of at least a two step mechanisms for inducing GTG
obesity
. To identify the satiety neuron transmitter, an analysis of certain enzyme activities involved in the synthesis of known transmitters, such as acetylcholine or gamma-aminobutyric acid (GABA), was made in the GTG-obese mice. There were no significant changes in any of the areas functionally related to the VMH.

Empirical support is provided for three basic strategies of improving the cost-effectiveness of treatments for
obesity
. The importance of analyzing both the effectiveness and cost of different program components when attempting to improve cost-effectiveness is illustrated in the first two studies. First, the strength of relationships between changes in different eating behaviors and changes in
obesity
was assessed for a small sample of obese individuals. Change in only one of eight behaviors investigated was significantly and strongly correlated with change in
obesity
. Data also were collected on the subjective costs and benefits of changing 36 eating behaviors that are commonly included in treatments for
obesity
. Some eating behaviors were found to differ greatly in subjective cost and perceived benefit, as measured by clients' ratings of component difficulty and component usefulness. A final, quasi-experimental study demonstrated the importance of developing cost-effective systems for translating principles of treatment for
obesity
into actual treatment. The impact on cost-effectiveness in mind is illustrated in a comparison of dollars paid by clients in relation to percent reduction in
obesity
for two weight reduction programs. The studies are discussed as highlighting the importance of measuring the cost and effectiveness of alternative delivery systems for, and different components of, treatments for
obesity
.

Swelling of the arm, mobility of the shoulder joint and muscle strength were examined in 76 patients with breast cancer 4.5 to 14 years (mean 8 years) after primary therapy. Marked arm swelling was found on the operated side in 31% of the patients operated by radical mastectomy and in 18% of those having undergone total mastectomy. The swelling was more marked in the upper arm than in the forearm. Patients irradiated postoperatively with a megavoltage technique showed more often and more oedema than those treated with a kilovoltage technique.
Obese
patients had more swelling than patients of normal weight. Of the various movements of the shoulder joint, abduction, adduction, flexion, extension, horizontal extension and internal rotation were significantly reduced on the operated side in comparison with the non-operated side, but the differences were not great. Neither swelling of the arm nor the patient's weight had any effect on the function of the shoulder joint, as expressed in terms of abduction. Of the muscle groups in the shoulder joint adductors, flexors and extensors were significantly weaker on the operated than on the non-operated side. The muscle strength of the operated side averaged 25% weaker than that of the control side. Swelling of the arm did not reduce the muscle strength of the shoulder joint.

Two women, aged 41 and 51 years, developed jaundice, encephalopathy, and hypoprothrombinemia during rapid weight loss four and 12 months after jejunoileal bypass for refractory
obesity
. Both were treated for liver failure and received a prolonged course of nutrition parenterally and orally. Serial liver biopsy specimens demonstrated extensive alcoholic-like hepatitis and cirrhosis that improved with nutritional repletion and reanastomosis. Postoperative biopsy specimens later demonstrated minimal portal fibrosis in one patient and inactive mild cirrhosis in the other. Although previous reports indicate that patients usually die when they develop liver failure of this severity after jejunoileal bypass, prolonged intensive nutritional repletion was associated with sufficient clinical and histologic improvement in these two patients so that intestinal reanastomosis could be performed safely.

Thiopental was administered for seizure control in 2 patients with uncontrollable seizures. Serum samples were collected from each patient and assayed for thiopental, and the resulting serum concentration--time data were analyzed pharmacokinetically. The biologic half-life in both patients was significantly longer than previously reported values. Based on the limited number of patients studied, it would appear that half-life and volume of distribution increase with the degree of
obesity
, while clearance remains unchanged. These pharmacokinetic characteristics would be worthy of consideration in cases where there may be prolonged use of thiopental, eg., for the control of uncontrollable seizures.
