Diagnosis of Idiopathic Pulmonary Fibrosis. An Official ATS/ERS/JRS/ALAT Clinical Practice Guideline.

Background: This document provides clinical recommendations for the diagnosis of idiopathic pulmonary fibrosis (IPF). It represents a collaborative effort between the American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society.

Methods: The evidence syntheses were discussed and recommendations formulated by a multidisciplinary committee of IPF experts.

Different oral corticosteroid regimens for acute asthma.

Background: Asthma is a common long-term breathing condition that affects approximately 300 million people worldwide. People with asthma may experience short-term worsening of their asthma symptoms; these episodes are often known as 'exacerbations', 'flare-ups', 'attacks' or 'acute asthma'. Oral steroids, which have a potent anti-inflammatory effect, are recommended for all but the most mild asthma exacerbations; they should be initiated promptly.

Incidence of ventilator associated pneumonia in burn patients with inhalation injury treated with high frequency percussive ventilation versus volume control ventilation: A systematic review.

Background: Pneumonia increases mortality in burn patients with inhalation injuries. We evaluated whether the use of High Frequency Percussive Ventilation (HFPV) in burn patients with inhalation injuries can decrease rates of Ventilator Associated Pneumonia (VAP) compared to Volume Control Ventilation (VCV).

Methods: Data were gathered from PubMed, EMBASE, Web of Science, reference lists, and hand search.

Early versus late surgical intervention or medical management for infective endocarditis: a systematic review and meta-analysis.

Objective: Infective endocarditis is associated with high morbidity and mortality and optimal timing for surgical intervention is unclear. We performed a systematic review and meta-analysis to compare early surgical intervention with conservative therapy in patients with infective endocarditis.

Methods: PubMed, Cochrane, EMBASE, CINAHL and Google-scholar databases were searched from January 1960 to April 2015.

Ocular adnexal marginal zone B cell lymphoma: a clinical and pathologic study of 23 cases.

To better characterize ocular adnexal marginal zone lymphoma of mucosa-associated lymphoid tissue (MZL-MALT), we analyzed the clinical and pathologic features of 23 patients (11 men, 12 women, median age 66 years). The tumor was confined to one ocular structure in 18 cases (conjunctiva, n=8; orbit, n=8; or lacrimal gland, n=2). Concurrent extraorbital disease was detected by the staging procedure in five patients, and preferentially involved other MALT sites.

HHV-8-associated T-cell lymphoma in a lymph node with concurrent peritoneal effusion in an HIV-positive man.

Primary effusion lymphoma (PEL) is an uncommon large cell lymphoma, usually seen in human immunodeficiency virus (HIV)-infected patients. PEL is characterized by various clinical, histomorphologic, and immunophenotypical features, and is associated with the human herpes virus 8 (HHV-8). PEL may present as either a body cavity-based lymphomatous effusion or a solid tumor mass.

Prognostic factors associated with the survival of patients developing loco-regional recurrences of differentiated thyroid carcinomas.

To estimate survival of patients with loco-regional recurrences (LRRs) of differentiated thyroid carcinomas (DTCs) and to identify factors associated with survival after LRRs, we analyzed retrospective data of the 172 patients treated and followed up in our institution from 1958 to 2000 who had developed LRRs (6% of DTC patients). Ultrasound, when used, picked up 95% of the recurrences. Survival was estimated with the method of Kaplan-Meier, and associated prognostic features were studied in univariate and multivariate Cox model-based analyses.
