Brown-bowel syndrome.

Extensive brownish discoloration of the small bowel is rare and has been described mainly in association with malabsorption disorders. It is related to deficiency of the fat soluble vitamin E. Vitamin E is an antioxidant substance that prevents peroxidation of unsaturated fatty acids. Vitamin E deficiency may result in oxidized lipids, which when polymerized with polysaccharides form the brown, PAS-positive pigment termed ceroid or lipofuscin. The deposition of pigmented granules in the effected tissues accounts for the brownish discoloration. We present three patients ultimately found to have "brown bowel syndrome (BBS)," in which the symptoms, preoperative findings, and respective diagnoses were different. In all three patients, serum Vitamin E levels were found to be extremely low.

Conservative surgery in Zollinger-Ellison syndrome: report of a case with an eight-year follow-up.

The patient described here, with malignant non-beta islet cell tumor of the head of the pancreas, was treated by resection of the tumor and metastases. Additional pathology of perforated duodenal ulcer and pyloric stenosis required vagotomy and pyloroplasty. The maintenance of normal gastrin levels after the operation indicates a good prognosis. We believe that the low-risk Zollinger-Ellison patient should be treated surgically and the tumor removed. When no tumor can be detected, parietal cell vagotomy should be performed to assist the pharmacological control of the gastric acid hypersecretion. Extensive surgery, such as total gastrectomy, is no longer the treatment of choice and is reserved for the so-called "cimetidine failure."

Endobronchial metastasis of renal cell carcinoma.

Endobronchial metastasis from nonpulmonary carcinoma is rare. A case of metastatic renal cell carcinoma is presented and the literature reviewed. Severe haemoptysis was the initial symptom leading to the finding of a bronchial polypoid mass.

Bilateral breast cancer.

Between the years 1972 and 1982, 1,880 women were treated for breast cancer at the Tel-Aviv Medical Center. One thousand two hundred fifteen detailed charts are included in our study. Sixty-six patients (5.4%) were diagnosed as having bilateral breast cancer. The mean age at first tumor diagnosis was 55.1 years. Bilateral breast cancer appears to be more common in nulligravidas and women who have delivered up to two children. In patients where the first tumor was greater than 4 cm in diameter, there was a higher incidence of a second tumor. A total of 65.2% of all patients who developed a second breast tumor had no axillary lymph node metastasis at the time the first breast tumor was diagnosed. There was no correlation between the histological types of the first and second tumors. The longer the woman survived after the first cancer diagnosis, the greater the likelihood of her developing a second tumor; the longer the interval between the diagnosis of the two cancers, the better the survival rate.

Gentamicin serum half-life: a comparison between pregnant and non-pregnant women.

The serum half-life of gentamicin following an intravenous dose was compared between 19 pregnant women (28-34 weeks of pregnancy) with premature rupture of the membranes and 17 non-pregnant women with pelvic inflammatory disease, the groups being age and weight matched. A significant reduction of gentamicin half-life was found in the pregnant group.

Lipoma of the colon. A report of 22 cases.

A series of 22 cases of lipomas of the colon is presented. Fourteen patients had small (mean size, 12.5 mm), asymptomatic colon lipomas which were diagnosed incidently. In four of these patients, more than one lipoma was found. Eight patients had one larger (mean size, 70.5 mm) symptomatic lipoma. The symptomatic patients were older (mean age, 64.3 years) than the asymptomatic patients (mean age, 54.7 years). While small lipomas do not generally give symptoms, it seems that the symptoms of larger lipomas are mainly due to mechanical interference in colonic passage or ulceration of the mucosa that covers the lipoma.

Transdermal therapeutic system scopolamine (TTSS), dimenhydrinate, and placebo--a comparative study at sea.

The efficacy of transdermally administered scopolamine was compared with the efficacy of oral dimenhydrinate and placebo therapy in the prevention of motion sickness at sea. Medication was administered on a controlled double blind basis to 140 subjects. A placebo effect reduced the motion sickness incidence (MSI) from 57.69% in the control group to 43.47%. Administration of dimenhydrinate reduced the MSI to 22.22% and the use of Transdermal Therapeutic System Scopolamine (TTSS) further reduced the MSI to 16.66%. TTSS afforded 61.67% protection against motion sickness at sea, compared to 48.88% protection with dimenhydrinate.

Furosemide effect on penicillin induced convulsions.

Convulsions were induced in 20 cats by the administration of intravenous penicillin. Furosemide administered together and after penicillin failed to reduce the seizure activity. Penicillin brain concentrations were not reduced by furosemide. Penicillin induced seizures are not affected by furosemide.

Mental health care in the Lebanon War, 1982.

Lessons in mental health care learned from the October 1973 War were applied in the Lebanon War 1982. A three-echelon system of management was followed according to the practices prevalent in Western armies. The clinical pictures were essentially similar to those observed in other wars. Combat stress reactions (CSR) comprised 15 to 20% of the total casualties during the active phase of the war; the rate of late reactions was 30 to 40% of the total CSR. Treatment on the battlefield was more effective than treatment following airlift to the rear, in returning soldiers to their units. The role of stress in causing CSR, and the importance of leadership and cohesion in its prevention were evident. The important lessons learned from the Lebanon War are discussed and include: 1) the need for a broad definition of CSR; 2) the importance of forward unit intervention; 3) the necessity of mobility and divisibility of mental health treatment units; 4) fighting units should not be dispersed immediately after combat; and 5) the management of stress reactions to be the responsibility not only of the mental health services, but of all sections of the medical corps, both in treatment and prevention.
