We present 3 patients with infective endocarditis due to Candida sp. They were not immunodeficient subjects, but they had major surgery, longterm antimicrobial therapy and prosthetic implants. Candida endocarditis is a difficult diagnosis for biological and technical. There is also poor results with and therapeutic reasons. The combined treatment with amphotericin B and 5-fluorocytosine, plus surgical removal of the infected tissue is recommended widely in the literature. 相似文献
The aim of the study was to determine the possible effect of melatonin treatment on disturbed sleep, fatigue and pain symptoms
observed in fibromyalgia (FM) patients. Twenty-one consecutive patients with FM were included in an open 4-week-duration pilot
study. Before and after treatment with melatonin 3 mg at bedtime, patients were evaluated using tender point count by palpation
of 18 classic anatomical regions, pain score in four predesignated areas, pain severity on a 10 cm visual analogue scale (VAS),
sleep disturbances, fatigue, depression, anxiety, and patient and physician global assessments, also by a VAS. Urine 6-sulphatoxymelatonin
levels (aMT-6S) were measured in the patients and 20 age- and sex-matched controls. Nineteen patients completed the study.
One patient withdrew because of migraine and another was lost to follow-up. At day 30, median values for the tender point
count and severity of pain at selected points, patient and physician global assessments and VAS for sleep significantly improved
with melatonin treatment. Other variables improved but did not reach statistical significance. Adverse events were mild and
transient. Lower levels of aMT-6S were found in FM patients compared with normal median controls (±SD, 9.16 ± 7.9 μg/24 h
vs 16.8 ± 12.8 μg/24 h) (p= 0.06). Although this is an open study, our preliminary results suggest that melatonin can be an alternative and safe treatment
for patients with FM. Double-blind placebo controlled studies are needed.

Introduction: Eosinophilic esophagitis (EoE) is a chronic, allergen-driven inflammatory esophageal disease characterized by predominantly eosinophilic inflammation leading to esophageal dysfunction. Recent efforts to understand EoE have increased our knowledge of the disease.
Areas covered: Multiple cells, molecules, and genes interplay with early life environmental factors in the pathophysiology of EoE to converge in the esophageal epithelium at the center of disease pathogenesis. Epithelial cells constitute a mayor cytokine source for TSLP and Calpain-14; an impaired epithelial barrier function allowing penetration of food and microbiota-derived antigens is involved in triggering and maintaining inflammation. Eosinophil and mast cell-derived products, including TGFβ, together with IL-1β and TNFα, promote epithelial mesenchymal transition in EoE, contributing to tissue remodeling by synthetizing and depositing extracellular matrix in subepithelial layers. This article aims to provide a state-of-the-art update on the pathophysiology of EoE applied to clinical practice, and latest research and developments with potential interest to improve the diagnosis and treatment of patients with EoE are revised.
Expert commentary: Preliminary approaches have provided promising results toward incorporating minimally invasive methods for patient diagnosis and monitoring in clinical practice. Early diagnosis and optimized therapies will allow for personalized medicine in EoE. 相似文献
Peptides of the corticotropin-releasing factor (CRF) family signal through the activation of two receptors, CRF receptor type 1 (CRFR1) and type 2 (CRFR2), both of which exist as multiple splice variants. We have identified a cDNA from mouse brain encoding a splice variant, soluble CRFR2alpha (sCRFR2alpha), in which exon 6 is deleted from the gene encoding CRFR2alpha. Translation of this isoform produces a predicted 143-aa soluble protein. The translated protein includes a majority of the first extracellular domain of the CRFR2alpha followed by a unique 38-aa hydrophilic C terminus resulting from a frame shift produced by deletion of exon 6. By using RT-PCR and Southern hybridization, the relative mRNA expression levels of full-length (seven transmembrane domains) CRFR2alpha and the soluble form (sCRFR2alpha) in the mouse brain were measured with a single reaction. The results demonstrate high levels of expression of sCRFR2alpha in the olfactory bulb, cortex, and midbrain regions. A rabbit antiserum raised against a synthetic peptide fragment encoding the unique C terminus revealed specific sCRFR2alpha immunoreactivity in mouse brain slices by immunohistochemistry and in extracts of brain regions by RIA. Interestingly, the sCRFR2alpha immunoreactivity distribution closely approximated that of CRFR1 expression in rodent brain. A protein corresponding to sCRFR2alpha, expressed and purified from either mammalian or bacterial cell systems, binds several CRF family ligands with low nanomolar affinities. Furthermore, the purified sCRFR2alpha protein inhibits cellular responses to CRF and urocortin 1. These data support a potential role of the sCRFR2alpha protein as a possible biological modulator of CRF family ligands. 相似文献
