Circulating levels of 25-OH vitamin D were measured in 44 patients who had undergone small intestinal bypass for obesity. Sixty-one percent had low circulating levels of the metabolite, which tended to normalize with time. This adaptive response also occurred for circulating total calcium, magnesium, albumin, and alkaline phosphatase. Serum concentrations of 25-OH vitamin D were directly related to total serum calcium and albumin. Impaired intestinal absorption of 25-OH vitamin D was seen in two patients. Following correction of total serum calcium for attendant hypoalbuminemia, 27% of patients remained hypocalcemic. The bone densities of two of 32 patients were low. In addition, skeletal biopsies of three of six patients were abnormal. It is concluded that small intestinal bypass results in at least transient deficits of circulating 25-OH vitamin D. As this operation may be associated with abnormal bone morphology, clinically significant skeletal disease may become apparent with long-term follow-up.

North American Indians have a higher morbidity from gallbladder disease, diabetes mellitus and obesity than other North Americans; this may result from their food intake. Nutrient intake and meal patterns were compared in 120 Micmac Indian and 115 Caucasian women in Shubenacadie, NS. Findings were compared with the Canadian Dietary Standard (CDS) and the Nutrition Canada national and Indian survey reports. The diet of Indian women had higher carbohydrate, lower protein and lower fibre content than that of Caucasian women, who derived a higher percentage of energy from protein and had a higher intake of vitamin A, niacin and ascorbic acid. Overnight fast was longer among Indian women. A high percentage of all women studied reported diets that did not reach the CDS for total energy intake in kilocalories or for calcium, iron, vitamin A, thiamin or riboflavin.

50 patients were operated on; 42 women and 8 men at the age of 17 to 57. The weight of the patients was 100 to 184 kg. and the overweight amounted in most cases to 70 to 188%. Long lasting conservative treatment proved to be inefficient. The endocrynological basis of the obesity was excluded. 6 patients were operated upon according to the Salmon-method and 44 according to the Payne-De Wind-method. 3 patients died. 47 patients recovered without complications. For two years after the operation the loss of weight was 28 to 50% compared with the initial weight. Diarrhoe stopped six months after the operation. During this time a decrease in the concentration of potassium and calcium in the blood serum was observed. Judging from the positive changes the decrease of the cholesterol concentration in the blood was observed as well as the general improvement of the patients health. All patients are in good health and have taken up their jobs again.

The relationship between blood pressure, ponderal index, sex, blood glucose, haemoglobin, serum uric acid, calcium cholesterol and creatinine, and albumin has been examined in 698 subjects aged between 44 and 49 years from the register of a group general practice. Sixty per cent of the variation in systolic pressure could be explained by statistically significant associations with diastolic pressure, sex, blood glucose, serum calcium, and cholesterol. The diastolic blood pressure (not corrected for systolic pressure) was significantly related only to ponderal index, haemoglobin in men, and cholesterol in women. Pulse pressure was also positively related to the risk factors blood glucose, serum cholesterol, and calcium. The possibility is discussed that one or more of these variables reduce aortic compliance and that the serum calcium contributes to this end. Diastolic, but not systolic pressure, had a prime association with relative weight, obesity being only basically associated with an increase in diastolic pressure.

A series of 36 patients with surgically proved primary hyperparathyroidism is reported. From this group a clinical profile consisting of obesity, anxiety, and/or depression in a mildly hypertensive, middleaged female was derived. Women constituted 92 percent of the patients. The serum calcium was confirmed again as the single most valuable test in the evaluation of this disorder.

Thirty-two patients, 28 women and 4 men aged from 17 to 57 years were treated surgically for obesity. Their body weight ranged from 90 to 184 kg, with an excess weight from 42% to 180%. In 6 cases the Salmon operation and in 26 the Payne-de Wind operation were performed. Two patients died. In the remaining cases the postoperative course was uneventful and relatively mild. The longest follow-up period was 22 months. Weight loss rate was highest in the first period after the operation and the monthly rate of the weight loss in the first year after the operation was 3.5 to 6 kg. Diarrhea disappeared usually after 4 months. In some patients a transient fall in serum potassium and calcium level was observed. Other favorable results included a significant fall in the serum levels of cholesterol and beta-lipoproteins and improved value of BSP retention test. The condition of the patients is good and they have returned to work.

The jejunoileal bypass is, of all the current therapeutic possibilities, the only permanent method for the successful treatment of a patient with hypothalamic obesity. Pre-operatively, it is advisable, however, to reduce the body weight by exclusive alimentation with Vivonex, in order to improve lung function and diminish the operation risks. Putting a smaller section of the bowel at rest will prevent major weight loss, as well as more severe complications. The disturbances of the calcium and potassium metabolism and of liver function, which frequently occur after jejunoileal bypass operation, were not observed, when on both sides of the immobilised bowel section a section of small bowel 23 to 38 cm long was maintained in normal function.

Of 93 patients with small bowel bypass for massive exogenous obesity, three developed calcium oxalate urinary calculi, four stones in their gallbladder, and one developed both gallstones and urinary calculi during a mean follow-up period of 17.6 plus or minus 9.0 months. The urinary oxalate excretion increased from 21.6 to 67.8 mg/24 hours (P smaller than .001); simultaneously, the urinary output decreased from 1,775 to 1,101 ml/24 hours (P smaller than .001). Postoperatively, there was a significant increase in the rate of bile salt synthesis from 1.6 to 4.9 gm/day (P smaller than .02) and in the bile sale glycine/taurine ratio from 4.6 to 6.8 (P smaller than .05). It is suggested that the postbypass increase in the biliary glycine/taurine ratio, with its consequent decrease in the zeta potential of the micelles in bile, is at least partly responsible for the increased incidence of cholelithlasis. The pathogenic basis for the increased incidence of urinary calculi is hyperoxaluria, which is probably related to an increased bile salt and glycine synthesis.

1. The contribution of school milk to the nutrition of 396 Kent primary schoolchildren aged 8-11 years was assessed using information collected in a survey which included a weighed-diet record, a socio-economic questionnaire and a medical examination. 2. Over half the children (59% for boys, 54% for girls) drank school milk every school day of the diet-record week. 3. Children who drank school milk every school day, when compared with those not drinking it, had a significantly higher mean daily intake of liquid milk, a higher total daily intake of several important nutrients including animal protein, calcium, thiamin and riboflavin, and a diet richer in Ca and riboflavin (boys) and animal protein and Ca (girls). They were also less likely to have intakes of Ca and riboflavin below the recommended daily intakes for these nutrients, (Department of Health and Social Security, 1969). 4. The increased nutritional intake associated with school milk consumption was not related to any differences in height, weight, arm circumference or skinfold thickness. 5. There was no evidence that school milk consumption was associated with obesity (as assessed clinically).

The experimental series by dogs and pigs show no specific absorption place in the small intestine--except the high selective absorption of vitamin B12 in the last ileum loop. Potassium absorption is better in the upper jejunum. For all other substances the conditions for absorption are the same in the jejunum as in the ileum. Calcium, carotin and cholesterol need a sufficiently extensive surface and show therefore a direct relation to the length of the small intestine. For the treatment of the extreme obesity we perform the jejunoileostomy with different lengths of jejunum and ileum. The hypercholesterinaemia type II can be treated by a partial ileum bypass. By the diminished absorption of the bile salts a sufficient decrease of the cholesterol level is possible, which amounts to about half the earlier value. The jejunoileostomy reduces not only overweight, but also improves the carbohydrate metabolism and lowers the increased fat levels.
