Revista chilena de pediatría , 2012,
Abstract: Introducción: Se ha estipulado que los ni os con condiciones crónicas de salud, pueden tener un alto riesgo de caries. Aunque la literatura sobre caries tempranas de la infancia (CTI) es extensa, poco se sabe acerca de su prevalencia en ni os con estas condiciones. Objetivo: Conocer la prevalencia de CTI en ni os con enfermedades respiratorias crónicas (ERC) en el Hospital Calvo Mackenna, Santiago, Chile y determinar su asociación con CTI. Pacientes y Método: Se realizó un estudio de corte transversal, sobre un total de 120 ni os de 2 a 5 a os 11 meses de edad, un grupo de estudio de 60 ni os con ERC y un grupo control de 60 ni os sanos fueron analizados. Se diagnosticó CTI de acuerdo a la definición aceptada por la AAPD, mediante un examen oral realizado por un operador bajo condiciones estandarizadas. Para el análisis estadístico se utilizó el programa Stata 11. Resultados: La prevalencia de CTI fue de 53% en ni os con ERC y 25% en ni os sanos (p < 0,0001). El valor de Qdds Ratio para ni os con ERC fue de 7,046 mostrando un incremento del riesgo de CTI, comparado con ni os sanos. (95% CI: 2,372-20,929). Conclusión: En esta población, los ni os con ERC presentan una alta prevalencia de CTI. En esta muestra se encontró una asociación estadísticamente significativa entre CTI y ERC. Introduction: Children with chronic health conditions may have an increased risk for developing caries. Although the literature on early childhood cavities (ECC) is extensive, little is known about its prevalence in children with these conditions. objective: To determine the prevalence of ECC in children with chronic respiratory disease (CRD) at Luis Calvo Mackenna Hospital in Santiago, Chile, and to determine their association. Patients and Methods: A cross-sectional study was performed on 120 children aged 2 to 5 years 11 months, a study group of 60 children with CRD and a control group of 60 healthy children were analyzed. ECC was diagnosed meeting the ALAPD criteria, an oral exam conducted by an operator under standardized conditions. The Stata 11 program was used for statistical analysis. results: The prevalence of ECC was 53% in children with CRD and 25% in healthy children (p < 0.0001). The value of odds ratio for children with CRD was 7.046 showing an increased risk of ECC compared with healthy children. (95% CI: 2.372 to 20.929). Conclusion: In this population, children with CRD have a high prevalence of ECC. In this sample, a statistically significant association between ECC and CRD was found.

Abstract: El riesgo de leishmaniasis visceral (LV) urbana epidémica se registró por primera vez en la Argentina en el a o 2004, por presencia del vector Lutzomyia longipalpis en la provincia de Formosa, la provincia de Misiones registra casos de LV humana, LV canina y vector en el a o 2006, y la provincia de Corrientes en el verano 2008-2009. En la provincia de Santiago del Estero los casos de LV humana y LV canina en el a o 2008 estuvieron asociados posiblemente a vectores secundarios. Por ello, para conocer la distribución del riesgo en la región del Chaco, entre enero y abril del 2010 se realizó la búsqueda sistemática del vector de LV en 30 localidades de las provincias de Formosa, Chaco y en la ciudad de Reconquista, Santa Fe (224 trampas/noche). Se comprobó la presencia de Lu. longipalpis, por primera vez, en las localidades de Resistencia y Puerto Antequera (Chaco). En Clorinda y Puerto Pilcomayo (Formosa) se obtuvieron las trampas con más ejemplares, 158 y 241 Lu. longipalpis trampa/sitio/noche respectivamente. Los resultados muestran que el vector de la LV urbana epidémica continúa dispersándose en el territorio argentino, habiendo ingresado a la provincia de Chaco. La notificación de casos esporádicos en la región chaque a, transmitidos por vectores secundarios, como Lu. migonei, podría aumentar también debido a la vigilancia intensificada, y a la dispersión del parásito asociada al tránsito de perros infectados, sintomáticos o asintomáticos. The appearance of the vector of visceral leishmaniasis (VL) Lutzomyia longipalpis in the province of Formosa in 2004 was associated with urban epidemic risk for the first time in Argentina. During 2006, vectors, canine and human cases of VL were reported in the province of Misiones, and in summer 2008-2009, in the province of Corrientes. In Santiago del Estero province in 2008, cases of human and canine VL were associated with secondary vectors. Therefore, with the aim to know the current distribution of VL risk in the Chaco region, systematic captures of the vector were performed between January and April 2010 in 30 localities of Formosa and Chaco, and in the city of Reconquista, province of Santa Fe (224 traps/night). Lu. longipalpis was reported for the first time in the cities of Resistencia and Puerto Antequera (Chaco). Clorinda and Puerto Pilcomayo (Formosa) are the localities where the traps with more individuals were obtained, 158 and 241 Lu. longipalpis trap / site / night respectively. These results showed that the vector of urban epidemic VL is still spreading in Argentina, and already reached the provin
Isolation and Characterization of 26 Microsatellite Loci for the Shortfin Silverside Fish Chirostoma humboldtianum Valenciennes1835 (Atherinopsidae: Menidiinae) Derived from Next Generation Sequencing and Their Cross-Amplification in Central Mexican Atherinopsids  [PDF]

Abstract:

The endemic silverside fish C. humboldtianum is of great ichtyologycal, economical and cultural relevance in central Mexico and it has been suggested that it is among a group of other “peces blancos”, the most ancestral species. Here we characterized a set of 26 microsatellite loci from the species in order to further assess population and phylogeographic issues that aid in evaluating their highly impacted populations. From 58 primer pairs tested on specimens from Villa Victoria dam (Rio Balsas Basin), 26 loci positively amplified on the species and cross-primed on specimens of the closely related and threatened Poblana alchichica, C. promelas and C. riojai. Loci resolved medium and high genetic variation (mean NA = 14.3, SD = 9.38; mean HO & HE = 0.47, SD = 0.32 and 0.58, SD = 0.32, respectively) and it is expected that these polymorphic loci are also useful in studing threatened atherinopsid species.

Síndrome de Diógenes: revis?o sistemática da literatura
Almeida,Rosa; Ribeiro,Oscar;
Revista Portuguesa de Saúde Pública , 2012, DOI: http://dx.doi.org/10.1016/j.rpsp.2012.03.004
Abstract: background: diogenes syndrome (ds) presents a growing international interest in clinical, social and public health research areas. it is characterized by a break and rejection of social patterns observed in a severe negligence in personal and environmental care, in a gradual isolation, in a reduced insight and in the accumulation behavior. many theoretical explanations have been presented but none covers entirely the complexity associated with the syndrome. objective: contribute to the systematization of scientific evidence about ds and to raise national awareness among clinical and social professionals for this syndrome. methods: the literature on ds was comprehensively reviewed [1960-2010] in english, french, spanish and portuguese languages, supplemented with research of associated nomenclature. 109 documents were considered for analysis and of these 67 case reports were collected and analysed by a grid built for that purpose. results: ds was found to be more common in older subjects (84%), single individuals (44%), who were living alone (64%) and in an apartment. ds cases were usually referenced by neighbors to the health care system as a result of a hazard to themselves or others. the determining criteria for the identification of the syndrome were social isolation and physical and domestic self-neglect. two thirds of the reports described psychiatric diagnoses that appeared to contribute to the presentation of the ds. discussion: ds is presented as a true syndrome that combines a multifactorial etiology. this entity seems to present a unique age-related feature, characterized by the manifestation of a different range of precipitating factors, supporting the argument that ds should be considered as a geriatric syndrome. main obstacles to intervention are isolation and the refusal of formal support that seems to reveal a mismatch between the needs of these individuals and the way services are provided.
