Article Synopsis
  • Cyclosporine maintenance therapy is effective in preventing acute rejection post-kidney transplant, but it can harm kidney function over time due to nephrotoxicity.* -
  • A study compared standard cyclosporine doses to lower doses in kidney transplant patients not taking corticosteroids and found that lower doses led to significantly lower treatment failure rates and better kidney function over two years.* -
  • The findings suggest that reducing cyclosporine exposure in these patients is both safe and beneficial for preserving kidney health.*

Superpotent topical corticosteroids (CS) have been demonstrated to improve bullous pemphigoid (BP) patients' survival. We assessed whether a mild regimen using lower doses of topical CS and a shorter duration could improve the outcome of BP patients even more. Three-hundred and twelve BP patients were included in a multicenter randomized controlled trial and stratified depending on the extent of BP as moderate (n=134) or extensive (n=178).

CXC chemokine receptor 4 (CXCR4) has been reported to be involved in organ-specific homing of breast cancer-derived metastasis. We investigated CXCR4 expression by immunohistochemistry as a possible new prognostic factor for primary breast cancer. Two groups of women treated for breast cancer in 1991 at the Centre for the fight against cancer of Upper Normandy-France (Centre de Lutte contre le Cancer de Haute Normandie) were assessed retrospectively.

Acute bronchiolitis is the main cause of emergency visits and hospitalizations in infants. Recent data suggest that neutrophil- and eosinophil-mediated inflammations were part of bronchiolitis pathophysiology. Apart from the defined risk factors, few was known on the underlying pathophysiology, which might point out the differences observed in the severity of the disease.

Background: Unexpected cases of bullous pemphigoid (BP) have been reported in adult patients with various neurological disorders suggesting a possible relationship between these diseases.

Objectives: (1) To determine the prevalence and types of neurological disorders in patients with BP, (2) to assess patients' functional impairment, and (3) to compare the clinical and biological findings as well as prognosis of BP patients presenting with or without neurological disorders.

Methods: BP patients with neurological disorders were selected in a series of 341 consecutive BP patients treated in 20 French Dermatology Departments.

Study Objective: Patients with acute cardiogenic pulmonary edema may develop respiratory failure. Noninvasive respiratory support should be initiated rapidly to avoid tracheal intubation. The aim of this study is to compare the efficacy of continuous positive airway pressure (CPAP) delivered by the Boussignac CPAP device and bilevel positive airway pressure (bilevel PAP) in patients with acute respiratory failure caused by acute cardiogenic pulmonary edema.

Background And Aims: Stress is often perceived by patients with inflammatory bowel disease (IBD) as the leading cause of their disease. The aim of this study was to assess whether stress, evaluated through life event (LE) occurrence, is associated with IBD onset.

Methods: Incident cases of IBD, including 167 patients with Crohn's disease (CD) and 74 with ulcerative colitis (UC), were compared with two control groups, one of 69 patients with acute self-limited colitis (ASLC) and another of 255 blood donors (BDs).

Background: Self-expanding metallic stents (SEMS) are a first-line therapeutic procedure in the palliative treatment of dysphagia in patients with esophageal cancer. However, the impact of SEMS insertion on patient nutritional status has never been assessed.

Objective: To evaluate the nutritional status of patients after insertion of a SEMS and the impact of a preexisting undernutrition status on survival.

Background: The Script Concordance test (SC) test is an assessment tool that measures the capacity to solve ill-defined problems, that is, reasoning in a context of uncertainty. This study assesses the feasibility, reliability and validity of the SC test made available on the Web to French urologists.

Methods: A 97 items SC test was developed based on major educational objectives of French urology training programmes.

Purpose: To develop a rat model of chronic Acanthamoeba polyphaga keratitis suitable for pharmacologic assessment of therapeutic agents.

Methods: An A. polyphaga isolate (ATCC #50495) was grown in peptone-yeast extract-glucose medium.

Objective: To assess prevalence and characteristics of opportunistic infections in patients with polymyositis/dermatomyositis (PM/DM). To determine the predictive values for opportunistic infections on clinical presentation, biochemical findings, and paraclinical features of PM/DM to detect patients at risk of opportunistic infections.

Methods: The medical records of 156 consecutive PM/DM patients in 3 medical centers were reviewed.

Background: It has been suggested that clonal T cells may play a critical role in the pathogenesis of systemic sclerosis.

Observations: A monoclonal population of T cells was found in blood samples from 13 (34%) of 38 consecutive patients with a definite diagnosis of systemic sclerosis who were prospectively examined by T-cell receptor gamma gene rearrangement using polymerase chain reaction analysis and denaturating gradient gel electrophoresis. In the healthy control group, the same type of examination revealed a monoclonal population of T cells in the blood samples from only 3 healthy subjects (4%)(odds ratio, 12.

Unlabelled: Ampullary carcinomas (AC) account for 33% of all surgically operable pancreatoduodenal tumors. The 5-year relative survival rate is 50% and tumoral stage is the main prognostic factor. However, among the three AC histological subtypes (intestinal, pancreatobiliary and mixed), a favorable prognostic has been reported for the intestinal subtype.

Background: Mesenteric ischemia and acidosis leading to intestinal ischemia has been observed during cardiopulmonary bypass (CPB) despite normal flow in the mesenteric vessels. The aim of this study was to assess mesenteric endothelium-dependent reactivity and vasoconstrictor responses of small mesenteric arteries in a rat model of CPB without aortic cross-clamping.

Methods: After femoral cannulation a partial 90 minutes CPB was performed with hemodynamics and blood gas parameters monitoring.

This study aimed to assess the short-term respiratory effects of a new portable device that delivers a continuous positive airway pressure via a face mask (Boussignac-CPAP) in patients with severe acute cardiogenic pulmonary oedema, and the feasibility of using this technique in an emergency department. We prospectively studied 30 consecutive patients with acute cardiogenic pulmonary oedema. They were randomly assigned either to the Boussignac-CPAP valve, which delivered oxygen, or to standard oxygen delivery for a duration of 30 min.

To distinguish between chondrosarcoma (grade 1--borderline histology) and enchondroma, we examined six chondrosarcomas (grade 1--borderline histology) which looked like benign lesions. Their diagnosis, albeit based on clinical, radiologic and pathologic examinations, was not easily reached. Moreover, we examined six enchondromas and 11 chondrosarcomas, the diagnoses of which were straightforward.

A change in the balance between proliferation and apoptosis in the course of hepatocellular carcinoma (HCC) development and progression has been suspected. We wanted to identify related genes whose mRNA levels could provide markers of severity and prognosis after resection. The extent of cell apoptosis, proliferation, and differentiation was measured with a terminal deoxynucleotidyl transferase-mediated deoxyuridine 5-triphosphate-biotin nick-end labeling assay, and the Ki-67 index was determined in paired tumor and cirrhotic tissue samples from patients who had undergone HCC resection after diagnosis of hepatitis C-related or alcoholism-related cirrhosis.

Background: Plasma viral load monitoring is an integral part of the standard of care for HIV-infected patients in industrialized countries. In developing countries, viral load assay is either unaffordable or hindered by on-site maintenance and/or technical problems.

Objectives: To evaluate a new and simple quantitative assay for plasma HIV reverse transcriptase (RT) activity; and to compare RT activity-based and RNA-based quantification in plasma samples from patients infected by different subtypes of HIV-1 group-M, HIV-1 group-O and HIV-2.
