Vitamin A loading--an indicator of post-prandial lipoprotein clearance in healthy and hypertriglyceridemic subjects.

To study post-prandial lipoprotein metabolism in normolipidemic and hypertriglyceridemic subjects, a vitamin A fat loading test was used. This method specifically labels dietary fat particles with retinyl palmitate (RP). Following RP concentrations, metabolic behavior of chylomicrons and chylomicron remnants were studied.

Fatty acid composition of adipose tissue in Ethiopian immigrants: a prospective study during their first year in Israel.

We measured the subcutaneous adipose tissue fatty acid composition in 22 male Ethiopian Jews, aged 17-65, shortly after their immigration to Israel. These subjects showed a concentration of linoleic acid (17.8%), which was relatively low compared with Israeli levels, and a high concentration of palmitic acid (28.

Prevalence of diabetes mellitus in Ethiopian immigrants.

The prevalence of diabetes mellitus among 445 new immigrant Ethiopian Jews was studied immediately after their arrival to Israel, and found to be 0.4%. This low prevalence could be attributed to their long trek accompanied by severe malnutrition which caused death to the old, weak and sick, leaving a selectively young and healthy population group.

ELISA for Campylobacter jejuni antibodies in Israeli children with diarrhea and in healthy soldiers.

An ELISA test was employed to detect Campylobacter jejuni antibodies, using as antigen the glycine-HCl buffer extract of a local isolate. The antibody response (IgG, IgA and IgM) was examined in a group of 32 children (age 0-12 years) with C. jejuni enteritis diagnosed by the isolation of the agent.

Hyponatremia in internal medicine ward patients: causes, treatment and prognosis.

A prospective study among unselected patients hospitalized in an internal medicine ward showed that 46 patients, 6.9% of total admissions, had serum concentrations of sodium less than 132 mEq/l. In 28.

Pregnancy and Cushing's syndrome: example of endocrine interaction.

Pregnancy rarely occurs in women with Cushing's syndrome, and when it does, fetal mortality and morbidity are very high. We describe a 30-year-old woman who was found to have severe Cushing's syndrome in the 22nd week of her first pregnancy, after a year of unsuccessful attempts to conceive. The patient had the majority of the symptoms and signs characteristic of the syndrome.

Sclerosing peritonitis. Possible early diagnosis by computerized tomography of the abdomen.

Sclerosing peritonitis (SP) has come to be recognized as a serious complication of peritoneal dialysis (PD). However, diagnosis is often established at a late stage of the disease and at laparotomy. The use of computerized tomography (CT) of the abdomen in 2 patients, clinically suspected of suffering from SP, revealed loculated ascites, adherent bowel loops, bowel lumenal narrowing, and thickening of the peritoneal membrane.

Severe sexual impairment produced by morbid obesity. Report of a case.

A 45-year-old man, was admitted for investigation of severe sexual impairment. During 20 years of marriage, he had had no normal sexual intercourse and the couple was childless. Physical examination disclosed a severely obese man (weight 300 kg, height 1.

Prolonged fever as a presenting symptom in adrenal tumors.

Four patients with adrenal tumors in whom prolonged fever was the foremost symptom are presented. Two of the patients had nonfunctional adrenocortical carcinoma, one had a pheochromocytoma without adrenergic hyperactivity, and in the fourth, an aldosteronoma was found. Only in 1 case was the tumor (pheochromocytoma) resectable and this patient became afebrile post surgery.

Rapid healing of diabetic foot ulcers with meticulous blood glucose control.

Fifteen diabetic patients, with neuropathic food ulcers refractory to conventional treatment, were found to be poorly balanced and were put on meticulous regimens; some on continuous subcutaneous insulin infusion and others on split mixed doses. Once diabetes was controlled, the wound healed rapidly in 11 of the patients within 4 to 13 weeks. In 4 patients amputation was necessary.

Bacteremic infections in granulopenic patients in Israel.

Forty-four bacteremic, granulopenic patients hospitalized during a 4-year period (between 1980 and 1983) in the Tel Aviv Medical Center are reviewed. Fifty-four organisms were recovered from the 44 patients, including 17 strains in 8 patients (18%) in mixed infections. Eighty-three percent of the organisms were gram-negative and 17% gram-positive.

Plasma lipid profile in verapamil-treated hypertensive patients.

Plasma lipid profiles were monitored for one year in hypertensive patients treated with verapamil. Elevations of triglyceride and very low density lipoprotein fractions were demonstrated in those patients already hyperlipidemic before commencement of verapamil. Caution may be necessary when giving verapamil to these hyperlipidemic patients.

Prolonged volume depletion imitating end-stage renal failure.

Four patients with chronic renal insufficiency were erroneously diagnosed as reaching the "end stage" of their disease. All of them had had insidious salt and water depletion prolonged over a period of 5 to 8 weeks. The correct diagnosis was missed because the signs and symptoms of slowly developing volume depletion were indistinguishable from the clinical picture of terminal uremia.
