Features of SLE in various ethnic groups in Israel.

Objective: To assess the association between the ethnic origin of patients with SLE living in Israel, and the clinical and laboratory features of SLE.

Methods: A retrospective review of medical records was carried out. Patients were classified into 3 groups based on their ethnic origin: a) Ashkenazi Jews, b) Sepharadic Jews and c) Arabs.

Allergy and SLE: common and variable.

Autoimmune conditions and allergic diseases are both characterized by immune dysregulation. The purpose of this study was to evaluate the incidence of various allergic disorders in patients with systemic lupus erythematosus (SLE). Sixty patients with SLE completed a questionnaire detailing their allergic disorders, which we compared with those of 60 age- and sex-matched healthy people.

Primary antiphospholipid syndrome emerging following thymectomy for myasthenia gravis: additional evidence for the kaleidoscope of autoimmunity.

The etiology of autoimmune diseases is multifactorial. In many of them the stimulation by a specific autoantigen is claimed to be responsible for the initiation of the disease. Alternatively, an autoimmune state may be induced by a pure dysregulation of the immune system.

Nitric oxide synthase induction with renal transplant rejection or infection.

Nitric oxide (NO) is readily oxidized to nitrate and nitrite and NO activates guanylyl cyclase, increasing cyclic GMP levels. To determine if nitric oxide synthase (NOS) is present in urine collected daily from patients following renal transplantation, we evaluated NOS activity in the leukocyte-rich particulate fraction and measured nitrate, nitrite, and cyclic GMP levels in the supernatant fraction of the urine. Reverse transcriptase-PCR and cDNA sequencing confirmed the presence of inducible NOS (iNOS) in cells obtained from the urine of renal transplant patients with rejection.

Phase I trial of intravenous carboplatin and cyclosporin A in refractory gynecologic cancer patients.

Our objective was to determine the maximum tolerated dose of cyclosporin A (CsA) delivered as a loading dose (LD) and continuous i.v. infusion (CI) in combination with carboplatin in patients with refractory gynecologic cancers.

Must living renal donors be hospitalized overnight prior to surgery?

To determine whether preoperative intravenous hydration was an important determinant of perioperative safety for the kidney donor or of early allograft function, 21 consecutive living donor transplants were assessed retrospectively. Donors hospitalized overnight received 1008 +/- 169 mL of intravenous fluid during the 8 h prior to operation, compared to no preoperative hydration among a cohort of 15 patients. No differences between intraoperative blood pressures, fluid administration, urine output, or time in the operating room were identified between groups.

No correlation between prolactin levels and clinical activity in patients with systemic lupus erythematosus.

Objective: To assess the frequency of hyperprolactinemia and its possible clinical significance in patients with systemic lupus erythematosus (SLE).

Methods: Concentrations of prolactin (PRL) were determined in 63 consecutive patients with SLE by an immunoradiometric assay. Antinuclear antibodies, anti-DNA, ribonucleoprotein, Sm, Ro, La, and anticardiolipin antibodies were determined by standard techniques.

A statistical survey of dioxin-like compounds in United States beef: a progress report.

The USEPA and the USDA have completed the first statistically designed survey of the occurrence and concentration of CDDs and CDFs in the fat of beef animals raised for human consumption in the United States. Back fat was sampled from 63 carcasses at federally inspected slaughter establishments nationwide. The sample design called for sampling beef animal classes in proportion to national annual slaughter statistics.

Comparison of clinical and laboratory parameters for systemic lupus erythematosus activity in Israelis versus Europeans.

The clinical activity of systemic lupus erythematosus (SLE) may be influenced by ethnic and environmental factors. The Consensus group on Activity Criteria for SLE attempted in a multicenter study to determine well-accepted criteria for disease activity. Of the 704 randomly assigned patients, 41 (5.

A regional experience with emergency liver transplantation.

Liver transplantation for patients requiring life-support results in the lowest survival and highest costs. A ten year (1983-1993) regional experience with liver transplantation for critically ill patients was undertaken to ascertain the fate of several subgroups of patients. Of the 828 liver transplants performed at six transplant centers within the region over this period, 168 (20%) were done in patients who met today's criteria for a United Network of Organ Sharing (UNOS) status 1 (emergency) liver transplant candidate.

Systemic lupus erythematosus and thymoma--a double-edged sword.

The coexistence of systemic lupus erythematosus (SLE) and thymoma is rare. We describe 2 female patients with this combination. A 48-year-old woman presented with dyspnea due to a left pleural effusion.

Enalapril treatment of posttransplant erythrocytosis: efficacy independent of circulating erythropoietin levels.

To determine the mechanism of action by which angiotensin-converting enzyme (ACE) inhibitors lower hematocrit in patients with posttransplant erythrocytosis, indices of red blood cell production and red blood cell destruction were obtained serially for 6 months from 10 renal transplant patients receiving treatment with enalapril for this problem. Before treatment, five patients had an elevated red blood cell mass, four had plasma volume contraction, and one had both. The mean hemoglobin concentration decreased by 2 g/dL (range, 0.

The presence of antiphospholipid antibodies in acute myocardial infarction.

This study was undertaken to determine if there is an association between increased titers of five different antiphospholipid antibodies (aPLA) in young patients' sera and the occurrence of acute myocardial infarction (AMI). Antibodies to anticardiolipin (aCL), anti-phosphatidylserine (aPS), antiphosphatidylinositol (aPI), anti-phosphatidylcholine (aPC), and anti-phosphatidylethanol amine (aPEA) were measured in 214 patients (102 patients, 102 healthy controls and 10 patients with antiphospholipid syndrome). These antibodies were measured twice (within 4h of onset of acute myocardial ischemic chest pain and 3 months after the myocardial infarction) by enzyme linked immunosorbent assay (ELISA).

Preemptive ganciclovir therapy to prevent cytomegalovirus disease in cytomegalovirus antibody-positive renal transplant recipients. A randomized controlled trial.

Objective: To determine whether preemptive ganciclovir therapy administered daily during antilymphocyte antibody therapy can prevent cytomegalovirus disease in renal transplant recipients who are positive for cytomegalovirus antibody.

Design: Randomized, controlled, multicenter trial.

Setting: 6 university-affiliated transplantation centers.

Anti-neuronal antibodies in antiphospholipid syndrome with central nervous system involvement: the difference from systemic lupus erythematosus.

The presence of antineuronal antibodies was compared in 43 patients with primary aPLS and 57 patients with neuropsychiatric SLE. Fifty-eight patients with Guillain-Barré syndrome and 72 normal healthy donors served as control groups. Seventeen patients in the study group had aPLS associated with CNS involvement.

Myelin- and microbe-specific antibodies in Guillain-Barré syndrome.

We surveyed the frequency of reported infections and target autoantigens in 56 Guillain Barré syndrome (GBS) patients by detecting antibodies to myelin and microbes. Sulfatide (43%), cardiolipin (48%), GD1a (15%), SGPG (11%), and GM3 (11%) antibodies were the most frequently detected heterogenous autoantibodies. A wide spectrum of antimicrobial IgG and IgM antibodies were also detected; mumps-specific IgG (66%), adenovirus-specific IgG (52%), varicella-zoster virus-specific IgG (46%), and S.

Strategies for success in academic surgery.

Background: A growing concern among university surgeons is a perceived threat to the traditional academician role. Factors that have led to this concern include (1) changes in reimbursement and patient referral patterns, both of which have resulted in reduced income; (2) mounting external pressure from the departmental chairperson/dean to generate professional fees; (3) pervasive ambiguity in the criteria for promotion and tenure; (4) intensified competition for research dollars in recent years; and (5) a perception that fellow academicians view surgeons as operating room technicians incapable of laboratory research. These cogent issues have the means to place academic goals in jeopardy.
