Primary immunodeficiency disorders (PIDs) have been described as diseases caused by one or more defects of the immune system. These patients are more likely to experience recurrent and/or severe infections and have a tendency to develop a wide range of complications. Respiratory diseases are the main and initial manifestation for the majority of PID patients and most common complication in this group of patients. Pulmonary complications present a significant cause of morbidity and also mortality among patients suffering from different forms of PIDs...

BACKGROUND: Clinically amyopathic dermatomyositis (CADM) is a distinct subgroup of dermatomyositis characterized by unique dermatologic manifestations without muscle involvement. CADM is frequently associated with interstitial lung disease (ILD), which usually has a rapidly progressive, fatal clinical course. Although CADM-related ILD (CADM-ILD) is well-described, data on the histopathology of CADM-ILD are limited. Organizing pneumonia and pulmonary vasculitis have rarely been reported...

A 71-year-old man was admitted to our hospital for dyspnea, which had worsened over a period of more than six months. He was previously diagnosed as having cryptogenic organizing pneumonia, and was treated with steroids in another hospital. He had complained of worsening dyspnea, despite the treatment. We performed video-assisted thoracoscopic surgery because of the high level of lactate dehydrogenase and inconsistency of the usual interstitial pneumonia pattern. Pathologic specimens showed atypical lymphocytes confined to the pulmonary capillaries...

BACKGROUND Idiopathic inflammatory myopathies are autoimmune disorders that can involve the skin, joints, muscles, and lungs. The most common of these disorders are dermatomyositis, polymyositis, overlap syndrome, and inclusion body myositis. Necrotizing autoimmune myopathy is an idiopathic inflammatory myopathy that is rarely associated with Sjögren's syndrome. The most common lung findings associated with anti-EJ antisynthetase syndrome are nonspecific interstitial pneumonia and usual interstitial pneumonia; this condition is rarely associated with fibrinous and organizing pneumonia...

OBJECTIVE: The presence of resistant microorganisms is a major cause of failure in initial empirical antimicrobial therapy. The objectives of this study are to determine the resistance profile of microorganisms that cause bacteraemia of abdominal origin and to identify whether the previous use of antibiotics and the place of acquisition of bacteraemia are risk factors associated with the presence of resistant organisms. MATERIAL AND METHODS: A clinical, observational, epidemiological, retrospective cohort study was conducted with all the adult patients admitted to a university hospital from 2011-2013...

Integrative and Conjugative Elements (ICEs) are widespread chromosomal mobile genetic elements, which can transfer autonomously by conjugation in bacteria. Thirteen ICEs with a conjugation module closely related to that of ICESt3 of Streptococcus thermophilus were characterized in Streptococcus salivarius by whole genome sequencing. Sequence comparison highlighted ICE evolution by shuffling of 3 different integration/excision modules (for integration in the 3' end of fda, rpsI or rpmG genes) with the conjugation module of the ICESt3 subfamily...

This work presents the complete nucleotide sequences of p0801-IMP from Klebsiella pneumoniae, p7121-IMP from K. oxytoca, and p17285-IMP from Citrobacter freundii, which are recovered from three different cases of nosocomial infection. These three plasmids represent the first fully sequenced blaIMP-carrying IncN2 plasmids. Further comparative genomics analysis of all the five integron-carrying IncN2 plasmids p0801-IMP, p7121-IMP, p17285-IMP, pJIE137, and p34983-59.134kb indicates that they possess conserved IncN2 backbones with limited genetic variations with respect to gene content and organization...

The spleen plays an integral protective role against encapsulated bacterial infections. Our understanding of the associated mechanisms is limited to thymus-independent (TI) antibody production by the marginal zone (MZ) B cells, leaving the contribution of other splenic compartments such as the red pulp (RP) largely unexplored despite asplenic patients succumbing to the infection in the first 24 h, suggesting important antibody-independent mechanisms. In this study, using time-lapse intravital imaging of the spleen, we identify a tropism for Streptococcus pneumoniae in this organ mediated by tissue-resident MZ and RP macrophages and a protective role for two distinct splenic neutrophil populations (Ly6G(hi) and Ly6G(intermediate)) residing in the splenic RP...

The indigenous intestinal microbiota is frequently considered an additional major organ of the human body and exerts profound immunomodulating activities. Germ-free (GF) mice display a significantly different inflammatory responsiveness pattern compared with conventional (CV) mice, and this was dubbed a "hyporesponsive phenotype." Taking into account that the deposition of immune complexes is a major event in acute inflammation and that GF mice have a distinct Ig repertoire and B cell activity, we aimed to evaluate whether this altered Ig repertoire interferes with the inflammatory responsiveness of GF mice...

BACKGROUND: Personal Emergency Response Systems (PERS) are traditionally used as fall alert systems for older adults, a population that contributes an overwhelming proportion of healthcare costs in the United States. Previous studies focused mainly on qualitative evaluations of PERS without a longitudinal quantitative evaluation of healthcare utilization in users. To address this gap and better understand the needs of older patients on PERS, we analyzed longitudinal healthcare utilization trends in patients using PERS through the home care management service of a large healthcare organization...

BACKGROUND: Gastric tubes are commonly used for the administration of drugs and tube feeding for people who are unable to swallow. Feeding via a tube misplaced in the trachea can result in severe pneumonia. Therefore, the confirmation of tube placement in the stomach after tube insertion is important. Recent studies have reported that ultrasonography provides good diagnostic accuracy estimates in the confirmation of appropriate tube placement. Hence, ultrasound could provide a promising alternative to X-rays in the confirmation of tube placement, especially in settings where X-ray facilities are unavailable or difficult to access...

BACKGROUND: Febrile neutropenia (FN) is common in cancer patients particularly hematologic malignancies due to intensive cytotoxic chemotherapy. It is an important cause of morbidity, mortality and treatment delays. The risk is greater in patients with ANC < 500/ mm3 and increases dramatically in those with ANC < 100/ mm3 and duration of neutropenia more than 1 week. AIMS AND OBJECTIVES: The purpose of this study was to evaluate the incidence, demographic characteristics, clinical profile, mortality, outcome and factors affecting the outcome in patients with febrile neutropenia (FN) admitted at our Center between January 2011 and November 2012...

REVIEW
Omar Ortega, Alberto Martín, Pere Clavé
Oropharyngeal dysphagia (OD) is a condition recognized by the World Health Organization and defined as the difficulty or inability to move a bolus safely and effectively from the oral cavity to the esophagus, and can include aspirations, choking, and residue. OD is pandemic among different phenotypes of older people, affecting between 27% and 91% of the population 70 years or older. Although OD can be diagnosed by well-defined clinical methods and complementary explorations, in the clinical setting OD is seldom systematically screened and treated, and awareness among the medical/geriatric community is scarce...
