Abstract: in order to better understand the epidemiological transmission network of leishmaniasis, an endemic disease in northeast brazil, we investigated the susceptibility of spix yellow-toothed cavies (galea spixii) to the leishmania infantum chagasi parasite. nine cavies were experimentally infected, separated into three groups and monitored at 30, 90 and 180 days, respectively. amastigotes were identified in the spleen slides of two cavies killed 180 days after infection. antibodies against the l. i. chagasi were identified in one of the cavies. this demonstrates that g. spixii is in fact capable of maintaining a stable infection by l. i. chagasi without alterations in biochemical and hematological parameters of the host and without perceivable micro and macroscopic lesions.

Abstract: Objectives: to investigate the knowledge, the attitudes and practices of the nurses students' in the specialization in Family Health, of the Institute of Continuous Education in PUC Sete Lagoas city, Belo Horizonte, Brasil. Methods: transversal, descriptive, study developed with 17 nurses, students of the Family Health Specialization, with volunteered to participate in the study. It was conducted toward the application of modified questionnaire with the thematic dental avulsion. The data were analyzed by descriptive statistical methods. Results: most of the nurses (71%) never heard before the term “dental avulsion”. Five nurses (29%) would not know which providences is necessary in case of dental avulsion, six (35%) would store the tooth and conduct the person to the dentist, three (18%) just direct the person to the dentist, one nurse (6%) would conduct the person to do the restoration, the other (6%) would store the tooth in milk and would give the tooth to the rescuer, and only one (6%) of them would make the replantation immediately. Conclusions: we can affirm that the analyzed nurses present inadequately knowledge when they were questioned about different aspects of urgency procedures in cases of dental avulsion.

Abstract: Oleic acid (OA) can induce acute lung injury in experimental models. In the present work, we used intratracheal OA injection to show augmented oedema formation, cell migration and activation, lipid mediator, and cytokine productions in the bronchoalveolar fluids of Swiss Webster mice. We also demonstrated that OA-induced pulmonary injury is dependent on ERK1/2 activation, since U0126, an inhibitor of ERK1/2 phosphorylation, blocked neutrophil migration, oedema, and lipid body formation as well as IL-6, but not IL-1β production. Using a mice strain carrying a null mutation for the TLR4 receptor, we proved that increased inflammatory parameters after OA challenges were not due to the activation of the TLR4 receptor. With OA being a Na/K-ATPase inhibitor, we suggest the possible involvement of this enzyme as an OA target triggering lung inflammation. 1. Introduction Adult respiratory distress syndrome (ARDS) description appeared in 1967, with 12 patients with refractory cyanosis to oxygenation therapy [1]. Recently, a draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (200?mm?Hg < PaO2/FIO2 ≤ 300?mm?Hg), moderate (100?mm?Hg < PaO2/FIO2 ≤ 200?mm?Hg), and severe (PaO2/FIO2 ≤ 100?mm?Hg) [2] which was nominated as Berlin definition, replacing the American-European consensus [3]. The initial lesion characterizing the exudative phase of ARDS is an increase in alveolar permeability to plasma proteins, leading to an interstitial and alveolar oedema [4, 5]. In the acute phase, cytokines and lipids are released, leading to alveolar-capillary barrier loss with hyaline membrane formation [6, 7]. In fact, ARDS is a diffuse alveolar damage secondary to an intense lung inflammatory response to an infectious, noninfectious, or extra pulmonary insult [8, 9]. ARDS can be induced by several factors such as systemic endotoxin release, pneumonia, drug overdose, acid aspiration, fat embolism, and pancreatitis [10–13] and can occur in pathological processes including sepsis, major trauma, or severe leptospirosis [8, 14, 15]. Resolution of the pulmonary oedema and lung inflammation are important determinants of ARDS outcome. Removal of alveolar fluid depends on transport of salt and water across the alveolar epithelium through apical sodium channels (ENaC) followed by extrusion to the lung interstitium via the Na-K-ATPase of alveolar epithelial cells [16–18]. Oleic acid (OA) is an inhibitor of the Na/K-ATPase activity in bovine serum [19] and is also a Na/K-ATPase inhibitor in a rabbit lung model, increasing endothelial

Abstract: pendred syndrome (ps) is an autossomal recessive disorder characterized by sensorineural deafness, goiter and iodide organification defect. the hearing loss is associated with inner ear abnormalities, ranging from an isolated enlarged vestibular aqueduct (eva) to a typical coclear dysplasia. mutations in the gene that encodes pendrin (slc26a4), a chloride/iodide transporter, have been shown to be associated with ps. we describe the clinical and molecular characteristics of a large consanguineous family harboring a mutation in the slc26a4 gene. the proband was a 26-year-old deaf brazilian woman who presented a bulky multinodular goiter and hypothyroidism since puberty. five other siblings were deaf: one brother had a similar phenotype, three siblings also had goiters but normal thyroid function tests, and one brother had only a subtle thyroid enlargement. other 4 siblings had no thyroid or hearing disorder. parents were first degree cousins and had normal hearing. the mother was healthy, except for subclinical hypothyroidism; the father was deceased. a perchlorate test in the proband showed a discharge of 21% of the incorporated iodide 2h after the administration of 1g of kclo4. audiological examinations showed profound hearing loss in all deaf subjects; ct and mri of the temporal bones showed eva in all of them. genomic dna was isolated from whole blood, from the 6 affected and 4 unaffected siblings, the mother and control. the coding region of the pds gene (exons 2-21), including exon/intron boundaries, were amplified by pcr and sequenced. a single base-pair (t) deletion at position 1197 of exon 10 was detected in homozygous state in the 6 deaf siblings. the mother and 2 unaffected siblings were heterozygous for this mutation, which has been described by everett et al. the 1197delt mutation is predicted to result in a frameshift and a truncated protein. the existence of ps phenocopies and intrafamilial phenotypic variability are well documented. the definite diagno
