Bronchiolitis: The New American Academy of Pediatrics Guidelines
2008
Respiratory Syncytial Virus (RSV) is the leading cause of hospitalization for lower respiratory tract infections (LRTI) in young children worldwide. RSV is an important cause of LRTI in infants and a variety of factors, such as gender, age at admission, gestational age, birth weight, and exposure to tobacco smoke and breast feeding may affect the prevalence of RSV-related disease and, possibly, the risk of developing asthma-like symptoms during the school years. AAP in 2006 formulated the new guidelines on diagnosis and management of bronchiolitis, giving recommendations on different conditions requesting clinical decisions also in terms of prevention.
Early identification of permanent maxillary canine impaction: A radiographic comparative study in a Mexican population
2019
Background Opportune diagnosis, prediction, and interceptive treatment of permanent maxillary canine (PMC) impaction is fundamental for pediatric dentists and orthodontists. In children and young adolescents, diagnostic information obtained from a panoramic radiograph is valuable for the overview and prediction of a potential PMC ectopic eruption into the oral cavity. The aim of the present study was to calculate and compare the prevalence of impaction of PMC in a Mexican pediatric sample (7 to 13 years old), through the use of the Ericson & Kurol (EK/L) and the Power & Short (PS) measurement analyses performed on panoramic radiographs. Material and methods This investigation was a cross-se…
Serum 25-hydroxyvitamin D levels in patients with cutaneous lupus erythematosus in a Mediterranean region
2010
Low vitamin D levels have been found in patients with autoimmune diseases, including type I diabetes, rheumatoid arthritis, multiple sclerosis and systemic lupus erythematosus. The main source of vitamin D is exposure to sunlight, but the same solar radiation is known to exacerbate lupus erythematosus. We investigated the prevalence of vitamin D insufficiency in patients with cutaneous lupus erythematosus (CLE). We designed a cross-sectional study including 55 patients with CLE to measure their serum 25-hydroxyvitamin D (25(OH)D) by chemiluminescence immunoassay and compare it with a control group consisting of 37 healthy sex and age-matched subjects recruited from the patients' relatives a…
Incidence and survival of human pathogens in French soils, impact of land use, pedoclimatic and biologic soil factors
2013
Soil contamination by bacterial pathogens can occur through manure, sewage sludge spreading or irrigation using waste water treatment plants effluents. Agricultural soils may act as reservoirs for these pathogens, play a significant role in their dissemination, leading to the potential contamination of food and water resources. Health risk associated with the occurrence of pathogens in environmental matrices has to be thoroughly evaluated. In this context, the objectives of this work were: i) to determine the prevalence of two pathogenic bacterial species (Listeria monocytogenes and Enterococcus faecalis) in a large collection of French soils originated from a systematic soil survey of the …
Protection of the European Energy Consumers’ Rights within the Globalization Context
2015
Abstract The ambivalence of globalization determines the consumer to comply with the legislation of the nation state as well as the UE legislation through the norms of the European Parliament regarding the rights of the European consumer, the labelling in the energetic field and the European Book of the consumer of energy. The consumers have the essential information that are to allow the attaining of objectives referring to the hedging of vulnerable citizens, less red tape, changing of the supplier, more information but also consumers’ hedging against the selling practices of non-loyal selling practices. The main objectives of the article aim at outlining the main theoretical methodologica…
Double parton correlations and constituent quark models: a light front approach to the valence sector
2014
An explicit evaluation of the double parton distribution functions (dPDFs), within a relativistic Light-Front approach to constituent quark models, is presented. dPDFs encode information on the correlations between two partons inside a target and represent the non-perturbative QCD ingredient for the description of double parton scattering in proton-proton collisions, a crucial issue in the search of new Physics at the LHC. Valence dPDFs are evaluated at the low scale of the model and the perturbative scale of the experiments is reached by means of QCD evolution. The present results show that the strong correlation effects present at the scale of the model are still sizable, in the valence r…
Familial hypercholesterolaemia: A global call to arms
2015
Familial Hypercholesterolaemia (FH) is the commonest autosomal co-dominantly inherited condition affecting man. It is caused by mutation in one of three genes, encoding the low-density lipoprotein (LDL) receptor, or the gene for apolipoprotein B (which is the major protein component of the LDL particle), or in the gene coding for PCSK9 (which is involved in the degradation of the LDL-receptor during its cellular recycling). These mutations result in impaired LDL metabolism, leading to life-long elevations in LDL-cholesterol (LDL-C) and development of premature atherosclerotic cardiovascular disease (ASCVD) [1], [2] and [3]. If left untreated, the relative risk of premature coronary artery d…
Serum antibodies to thymus epithelial cells in non-A, non-B and cryptogenic chronic liver disease
2008
Antibodies against thymus epithelial cells (anti-TEC) and the basal cell layer (BCLA) of squamous epithelia have been described in association with HDV-related chronic liver disease (CLD). Data are lacking on their presence during nAnB virus infection. Sera from 51 patients with nAnB post-transfusion hepatitis, including acute and chronic cases diagnosed during a prospective study on candidates for cardiac surgery, and 167 with various forms of CLD were tested for the presence of anti-TEC and BCLA using indirect immunofluorescence on human thymus and rat forestomach sections. Both antibodies mainly occurred in nAnB, HDV and cryptogenic CLD (anti-TEC: 51%, 47% and 42%; BCLA: 29%, 38% and 31%…
Inflammatory papillary hyperplasia: a systematic review
2017
Introduction Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa. It is usually found in denture-wearers but also has been reported in patients without a history of use of a maxillary prosthesis use. Objetives The aim of this study is to review the literature to assess the prevalence of denture stomatitis and inflammatory papillary hyperplasia and the etiological factors associated. Material and Methods A search was carried out in PubMed (January 2005 to October 2015) with the key words “inflammatory papillary hyperplasia”, “denture stomatitis”, “granular stomatitis” and “Newton’s type III” The inclusion criteria were studies including at least a sample of 50 a…
