Guillain-Barré syndrome (GBS) is often preceded by an infectious disease. A case of GBS after hepatitis A in a pregnant woman is described. The patient was treated with intravenous immunoglobulin and had full recovery with no neurologic sequelae. She gave birth in term to a healthy baby. This is the first reported case in the English literature of a triple condition of hepatitis A, GBS, and pregnancy.

"Sharap" is a private medical service integrated within our public clinic and hospital services. Clients may choose their physician by paying a fee in addition to what their health insurance agency (Kupat Holim) pays for. All other hospital services are supplied to all patients alike. The main purpose of this study was to evaluate the extent to which this declared policy is maintained in practice. During 5 months in 1997, 198 Sharap patients and 198 regular patients were interviewed in the the general surgery, cardiac surgery, ENT, cardiology, newborn and gynecology wards of this hospital. Both groups were similar in regard to cause of hospitalization, gender, age group (10-year age ranges), and length of hospitalization (at least 24 hours). Similar levels of satisfaction with hospitalization in general and with the nursing service and with supportive services were found in both groups. However, Sharap patients were more satisfied with their physicians than regular patients (87% vs 74%, respectively). Similar results were also found using indirect measures of satisfaction. About 86% in both groups reported having achieved the goal of improvement in health. A high proportion of respondents from both groups (82% and 88%, respectively) could not distinguish between Sharap and regular patients in the ward. However, a greater proportion of regular patients (35% vs 21%) wanted more extensive explanations from their physicians regarding their treatment. Sharap patients belonged to higher socio-economic classes than regular patients. Our evaluation indicates that although the Sharap service enables the affluent to choose their preferred physician, resulting in a different doctor-patient relationship, the service does not create a significant feeling of discrimination among hospitalized patients, and does not interfere with the high level of health services available to the public at large.
We describe a 73-year-old male who developed native valve infective endocarditis due to Staphylococcus capitis as a consequence of repeated oesophageal dilatation. The patient was treated with appropriate antibiotic therapy but his condition deteriorated and he died. We review 10 previously reported cases of infective endocarditis associated with upper endoscopy and discuss the issue of prophylaxis of high risk patients prior to upper endoscopy involving various invasive procedures, e.g. biopsy, dilatation and sclerotherapy.
Lipoamide dehydrogenase deficiency is a rare disease, manifested in early childhood by lactic acidemia, progressive neurological damage and death in most cases. We report a case of lipoamide dehydrogenase deficiency in a 34-year-old Ashkenazi-Jewish woman. The deficiency manifested as acute hepatitis without cognitive impairment or acidosis. The patient's brother also had lipoamide dehydrogenase deficiency, diagnosed at the age of 20, and manifested as hepatocellular damage, lactic acidemia and myoglobinuria. We assume that the trigger for this hepatocellular damage was prolonged fasting, and that otherwise the patient might have gone undiagnosed. Other cases in Ashkenazi Jews of mild lipoamide dehydrogenase deficiency with hepatocellular injury but without central nervous system involvement are reviewed.
The approach described in this paper is predicated on the fundamental belief that in order to become competent and ethical practitioners, students must understand themselves and how they see others. They must be given tools and skills that facilitate examination of their own assumptions and beliefs about themselves, others, and how the world works. It is also essential that students examine how these assumptions and beliefs will influence the way they choose to conduct therapy. Once they are aware of their biases, they must learn to choose to consciously influence themselves in a way that permits their clients the largest room for change within the clients' own contexts of belief, understanding, experience, and possibility. In this paper I describe the use of the genogram as a tool to facilitate the process of gaining self knowledge. This tool has been used in a multicultural counseling course, as well as in professional development workshops for psychologists, mental health counselors, and marriage and family therapists.

A 39 year-old patient with long-standing diagnosis of pelvic endometriosis had been treated for over twenty years with oral contraceptives (OCs). A year prior to admission to the gynecological ward, an ultrasonographic examination revealed three hepatic lesions, which were not reported in previous liver sonography. These lesions progressed during OC use, over the next six months. Liver function tests were normal. Liver scan, CT and ultrasound imaging techniques supported the diagnosis of solid hepatic tumors. These lesions developed concomitantly to long-term use of OCs, therefore discontinuation of therapy was mandatory. Six months later, the patient was hospitalized due to pelvic pain. She underwent total abdominal hysterectomy and left salpingo-oophorectomy (the right adnexa had been removed years before). Due to the patient's young age, hormone replacement therapy was indicated. The preferred preparation was transdermal estradiol due to the fact that systemic absorption has no hepatic first-pass effect and therefore exerts minimal influence on liver enzymes and functions. Serial ultrasonographic examinations, performed while under treatment with transdermal estradiol, showed complete regression of the hepatic lesions over a period of two years. Our report demonstrates regression of multifocal hepatic tumors despite transdermal estradiol replacement therapy.
A 23-year-old Ethiopian new immigrant presented with a giant lymphangioma extending from the posterior mediastinum through the retroperitoneum, ending as a herniated fluid-filled sac in the inguinal region. Chylous fluid aspirated from within the lymphangioma was cultured positive for Mycobacterium tuberculosis. Considerable regression occurred following 6 months of antituberculous treatment.
Functional adaptation of the remnant intestine after extensive resection of small bowel is well documented. The effects of partial resection of large bowel on the remaining colon have not been characterized. Transepithelial potential (VT), tissue resistance (RT), and short-circuit current (Isc) were measured in vitro across distal colonic tissue of rats three weeks after proximal hemicolectomy with ileotransversotomy and compared to the same parameters measured in the distal colon of control animals. In a second series of experiments, an in vivo perfusion technique was used to measure changes in sodium, potassium, and water transport in distal colon following proximal hemicolectomy. A 2.5-fold increase in VT (P less than 0.01), a 62% increase in RT (P less than 0.001), and a 35% increase in Isc (P less than 0.05) were observed three weeks following hemicolectomy when compared to control animals. A 64% increase in net sodium absorption (P less than 0.025), no significant change in net potassium transport, and a 115% increase in net water absorption (P less than 0.01) were demonstrated in hemicolectomized animals when compared to control. It is concluded that in the rat the distal colon is capable of functional adaptation to increase net sodium and water absorption within three weeks after proximal hemicolectomy. The mechanism responsible for this adaptive process has yet to be defined. Our findings may explain the lack of chronic diarrhea in patients undergoing right hemicolectomy.

Whereas, in chronic type B hepatitis, the therapeutic effect of alpha-interferon has been studied extensively, data on the effect of interferon on the course and prognosis of acute hepatitis B are scarce in the literature. We report a case of acute type B hepatitis complicated by life-threatening extrahepatic manifestations where recombinant alpha-interferon facilitated clinical, biochemical, and serological recovery.
Clinical and laboratory features of 17 patients over 40 years of age (mean age: 55 years) admitted with infectious mononucleosis were compared with those of 17 adolescents (mean age: 13 years) hospitalized with this illness. Elderly patients with infectious mononucleosis were found to run a longer febrile course (13 vs. 7 days, p less than 0.01) and to have a lower peak total white blood cell count (6,600/mm3 vs. 11,000/mm3, p less than 0.001) and a lower incidence of splenomegaly (50% vs. 76%, p less than 0.05), lymphadenopathy (25% vs. 94%, p less than 0.001), and pharyngitis (25% vs. 47%, p less than 0.05), compared with young patients with infectious mononucleosis. Patients in both groups had a high prevalence of abnormal liver function tests. It is concluded that infectious mononucleosis in patients over 40 years of age is not as uncommon as previously reported, and that clinical and laboratory features differ between young and older patients suffering from this disease.
Studies were performed, using a synthetic glucocorticoid, RU 28362, that has negligible binding to aldosterone receptors, to examine whether the effect of glucocorticoids on the electrical properties of rat distal colon involves a specific mechanism or crossover binding to aldosterone receptor sites. Compared with control, RU 28362, in a dose of 70 micrograms.100 g body wt-1.day-1, increased transepithelial potential differences (VT) twofold and the equivalent short-circuit current (ISC) threefold; epithelial resistance (RT) was reduced 25%. These changes were qualitatively similar to, but less than, the changes induced by the same dose of aldosterone. The effects of dexamethasone in the same dose were indistinguishable from the changes caused by aldosterone. The results of cell-impalement studies corresponded to whole epithelial changes; RU 28362 induced a small increase in basolateral potential difference, from -43 +/- 2 to -45 +/- 1 mV, and a fall in apical potential difference, from 40 +/- 2 to 36 +/- 1 mV, but these effects on cell membrane voltage were less than caused by either aldosterone or dexamethasone. In contrast to the marked inhibitory action of amiloride to reduce VT in aldosterone- and dexamethasone-treated animals, this sodium channel blocker had no effect on VT in RU 28362-treated animals. Similarly, while spironolactone caused marked inhibition of the changes in VT, RT, and ISC induced by aldosterone, the inhibitory action on tissue from RU 28362-treated animals was slight or absent. These results suggest that glucocorticoids have a specific aldosterone receptor-independent action on the electrical properties of the large intestine.
