ABSTRACT
Abstract This study evaluated the parasite fauna on the gills of spotted goatfish Pseudupeneus maculatus captured in the dry and rainy seasons in the coast of the State of Pernambuco, Brazil. Eight parasite species were identified belonging to the following taxa: Monogenea (Haliotrema caraïbensis, Haliotrema caballeroi and Haliotrema golvani); Crustacea (Rocinela signata, Hamaticolax scutigerulus and Caligidae gen. sp.) and Cestoda (Nybelinia indica and Pseudolacistorhynchus noodti). The most prevalent parasites were: Monogenea (100%), H. scutigerulus (35%), N. indica (11.7%), R. signata (8.3%), Caligidae gen. sp. (3.33%) and P. noodti (0.83%). Values of infestation are compared to other studies, and the uncommon occurrence of Trypanorhyncha on the gills suggests that the spotted goatfish could be an intermediate host for the parasite.
Resumo O presente estudo investigou a fauna parasitária das brânquias do peixe conhecido como saramunete Pseudupeneus maculatus, capturados nas estações seca e chuvosa na costa do estado de Pernambuco, Brasil. Oito espécies de parasitos foram identificadas, pertencentes aos seguintes táxons: Monogenea (Haliotrema caraïbensis, Haliotrema caballeroi e Haliotrema golvani); Crustacea (Rocinela signata, Hamaticolax scutigerulus e Caligidae gen. sp.) e Cestoda (Nybelinia indica e Pseudolacistorhynchus noodti). Os parasitos mais prevalentes foram: Monogenea (100%), H. scutigerulus (35%), N. indica (11,7%), R. signata (8,3%), Caligidae gen. sp. (3,33%) e P. noodti (0,83%). Os valores de infestação são comparados a outros estudos, e a ocorrência incomum de cestóides Trypanorhyncha sugere que o saramunete pode ser um hospedeiro intermediário para o parasito.

Background: Although it is well known that allergic diseases involve a strong Th2 immune response, with production of high levels of specific IgE allergen, knowledge on the association between filarial infection and allergies, among paediatric patients is scarce. Objective: To evaluate the allergic response patterns in cases of filarial infection by comparing peripheral eosinophils, total IgE levels, immediate hypersensitivity and cytokine levels in children and adolescents in Brazil. Methods: This was an exploratory study with three groups: (I) with filarial infection and without allergic diseases; (II) without filarial infection and with allergic diseases; and (III) without filarial infection and without allergic diseases. The prick test and specific IgE tests for aeroallergens were performed using five antigens. Peripheral eosinophils and total IgE were also evaluated. IL-4 and IL-5 were determined using whole-blood culture stimulated by three antigens. Results: Eosinophilia and elevated levels of total IgE (≥ 400IU/dl) were observed in all groups. The prick test was positive in 56.6% of the cases. Group I presented hypersensitive responses similar to the allergic disease groups. In the whole-blood culture stimulated by Dermatophagoides pteronyssinus, average IL-4 production did not differ significantly among the groups, but IL5 production resulting from stimulation was greater in the allergic disease groups (p < 0.05). Conclusions: The allergic response pattern in group with filarial infection was similar to that of the groups with and without allergic diseases, but the response to IL-5 in the culture stimulated by D. pteronyssinus was an exclusive characteristic of the allergic group (AU)

ABSTRACT
Background: Severe combined immunodeficiency (SCID) is one of the most severe forms of primary immunodeficiency. The objectives of this study were to analyze the diagnosis, treatment, and prognosis of SCID in Brazil and to document the impact of BCG vaccine. Methods: We actively searched for cases by contacting all Brazilian referral centers. Results: We contacted 23 centers and 70 patients from 65 families. Patients were born between 1996 and 2011, and 49 (70%) were male. More than half (39) of the diagnoses were made after 2006. Mean age at diagnosis declined from 9.7 to 6.1 months ( P= .058) before and after 2000, respectively, and mean delay in diagnosis decreased from 7.9 to 4.2 months ( P= .009). Most patients (60/70) were vaccinated with BCG before the diagnosis, 39 of 60 (65%) had complications related to BCG vaccine, and the complication was disseminated in 29 of 39 (74.3%). Less than half of the patients (30, 42.9%) underwent hematopoietic stem cell transplantation (HSCT). Half of the patients died (35, 50%), and 23 of these patients had not undergone HSCT. Disseminated BCG was the cause of death, either alone or in association with other causes, in 9 of 31 cases (29%, no data for 4 cases). Conclusions: In Brazil, diagnosis of SCID has improved over the last decade, both in terms of the number of cases and age at diagnosis, although a much higher number of cases had been expected. Mortality is higher than in developed countries. Complications of BCG vaccine are an important warning sign for the presence of SCID and account for significant morbidity during disease progression (AU)
Antecedentes: La inmunodeficiencia severa combinada (IDSC) es una de las formas más graves de la inmunodeficiencia primaria. El objetivo de este estudio fue analizar el estado del diagnóstico, tratamiento y pronóstico de esta enfermedad en Brasil y documentar el impacto de la vacunación con BCG (bacillus Calmette-Guérin). Métodos: Los casos fueron seleccionados tras contactar con los centros de referencia de Brasil. Resultados: Se contactaron 23 centros en total, que permitieron recopilar a 70 pacientes entre los años 1996 y 2011 procedentes de 65 familias, 49 de ellos (70%) varones. En más de la mitad de ellos (39), el diagnóstico fue realizado con posteriridad al año 2006. La edad media en el diagnóstico varió entre los 9,7 a los 6,1 meses (p=0.058), antes y después del año 2000, respectivamente, y el tiempo en que se realizó el diagnóstico disminuyó de los 7,9 a los 4,2 meses (p=0.009). La mayoría de ellos (60/70) se habían vacunado con BCG antes del diagnóstico, 39/60 (65%) tuvieron complicaciones con la BCG y en 29/39 (74.3%) la enfermedad se diseminó. En menos de la mitad de los pacientes (30/70, 42,9%) se realizó un trasplate de células madre (HSCT). La mitad de los pacientes (35/70, 50%) murieron; 23/35 de ellos sin HSCT. La diseminación del BCG fue la causa de la muerte, sola o asociada con otras causas, en 9/31 casos (29%, en 4 casos sin datos). Conclusiones: En conclusión, el diagnóstico de IDSC en Brasil ha mejorado en la última década, tanto en términos numéricos, cómo respecto a la edad de detección de la enfermedad. La mortalidad es alta en comparación con los países desarrollados. La vacuna con BCG provoca complicaciones importantes en estos pacientes, lo cual alerta sobre el posible diagnóstico y progresión de esta enfermedad (AU)

We transplanted 47 patients with Fanconi anemia using an alternative source of hematopoietic cells. The patients were assigned to the following groups: group 1, unrelated bone marrow (N = 15); group 2, unrelated cord blood (N = 17), and group 3, related non-sibling bone marrow (N = 15). Twenty-four patients (51 percent) had complete engraftment, which was not influenced by gender (P = 0.87), age (P = 0.45), dose of cyclophosphamide (P = 0.80), nucleated cell dose infused (P = 0.60), or use of anti-T serotherapy (P = 0.20). Favorable factors for superior engraftment were full HLA compatibility (independent of the source of cells; P = 0.007) and use of a fludarabine-based conditioning regimen (P = 0.046). Unfavorable factors were > or = 25 transfusions pre-transplant (P = 0.011) and degree of HLA disparity (P = 0.007). Intensity of mucositis (P = 0.50) and use of androgen prior to transplant had no influence on survival (P = 0.80). Acute graft-versus-host disease (GVHD) grade II-IV and chronic GVHD were diagnosed in 47 and 23 percent of available patients, respectively, and infections prevailed as the main cause of death, associated or not with GVHD. Eighteen patients are alive, the Kaplan-Meyer overall survival is 38 percent at ~8 years, and the best results were obtained with related non-sibling bone marrow patients. Three recommendations emerged from the present study: fludarabine as part of conditioning, transplant in patients with <25 transfusions and avoidance of HLA disparity. In addition, an extended family search (even when consanguinity is not present) seeking for a related non-sibling donor is highly recommended.

No presente trabalho foi realizado um estudo da técnica cirúrgica de coleta de embriöes na espécie caprina, utilizando-se doadoras heterozigotas para a translocaçäo 5/15, acasaladas com animal translocado. Simultaneamente foram observados aspectos técnicos inerentes à criopreservaçäo, descongelaçäo e cultivo das estruturas recuperadas. Frente ao tratamento superovulatório, o cio foi observado em 24 ou 48 horas após a remoçäo da esponja intravaginal e foram recuperadas 71 estruturas viáveis em 43 coletas. O 1-2 Propanodiol mostrou-se eficiente criopreservador, permitindo cultivo de todos os embriöes, fato näo observado quando utilizou-se o Glicerol. As aderências provocadas pelas repetidas coletas constituem-se no grande desafio no sentido de se aperfeiçoar a técnica, pois säo consideradas um fator limitante ao uso de doadores no início da vida reprodutiva
