Multiple endocrine neoplasia type 2 (MEN 2) is an autosomal dominant inherited disease, characterized by germ-line variants in RET proto-oncogene. Variants are frequently located in the RET extracellular cysteine-rich region domain, mainly affecting cysteines which are replaced by an alternative amino acid, resulting in a mispaired cysteine and the generation of RET dimers. We describe a novel c.

Introduction And Aim: Pseudomonas aeruginosa could acquire a mucoid phenotype due to mutations in mucA (mucoid Pseudomonas aeruginosa - mPA) that is a hallmark of poor prognosis in patients with bronchiectasis. Despite the higher prevalence of Pseudomonas aeruginosa in bronchiectasis, how mPA and non-mucoid Pseudomonas aeruginosa (non-mPA) phenotypes could affect viscoelastic properties of sputum is unknown. Our aim was to determine the relationship between Pseudomonas aeruginosa phenotypes isolation, the viscoelastic properties of sputum and the clinical outcomes in patients with bronchiectasis.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with limited response to currently available therapies. Alveolar type II (ATII) cells act as progenitor cells in the adult lung, contributing to alveolar repair during pulmonary injury. However, in IPF, ATII cells die and are replaced by fibroblasts and myofibroblasts.

Information regarding the processes leading to death in patients with invasive aspergillosis (IA) is lacking. We sought to determine the causes of death in these patients, the role that IA played in the cause, and the timing of death. The factors associated with IA-related mortality are also analyzed.

Objective: To assess the efficacy of linezolid compared with vancomycin in an experimental model of pneumonia induced by methicillin-resistant Staphylococcus aureus (MRSA) in ventilated pigs.

Methods: Forty pigs (30 kg) were intubated and challenged via bronchoscopy with a suspension of 106 colony forming units of MRSA into every lobe. Afterwards, pigs were ventilated up to 96 hours.

The aim of our study was to determine the usefulness of pneumococcal urinary antigen (UA) collected in the emergency department (ED) for the microbiologic diagnosis of community-acquired pneumonia (CAP) in HIV patients and to compare it with other diagnostic tests. Prospective study from 1 January 2007 to 31 December 2008 included HIV-infected patients admitted at the ED with respiratory symptoms and who were diagnosed of CAP. UA, two blood cultures and sputum sample for culture determination were collected from every patient.

Objective: To prospectively evaluate the predictive factors for the nonresponse to empirical antibiotic treatment and mortality in patients with intensive care unit-acquired pneumonia.

Design: A 1-yr prospective cohort of patients with suspicion of intensive care unit-acquired pneumonia.

Setting: Five medical and surgical intensive care units of Hospital Clinic in Barcelona.
