Abstract:

Dental plaque in adult patients is well identified as a reservoir for Helicobacter pylori. This question still remains unclear in children. The aim of this study is to identify the presence of this bacterium in dental plaque of Mexican pediatric patients, using Real Time Polymerase Chain Reaction (qPCR). Forty patients from 2 to 11 years without dyspeptic symptoms were enrolled. Samples were collected from the subgingival space of the lingual side of the lower molars and cultured in selective medium. Therefore, qPCR analysis was conducted. According to the results obtained in this study, it was found that 35% of the pediatric population who participated tested qPCR positive for the presence of H. pylori in dental plaque samples. No significant associations were detected among isolation rate by gender or age. We found that dental plaque may be a reservoir for H. pylori. However, more research is needed to establish the way of the infection of pediatric population.

Abstract: Un desafío de la gestión de los recursos humanos en las peque as y medianas empresas (pymes) es analizar las prácticas de liderazgo. Esta investigación indagó por la frecuencia del uso del liderazgo por parte de los gerentes de las pymes del estado de Tamaulipas, México. El estudio analizó cinco comportamientos del Inventario de las Prácticas de Liderazgo (IPL). A los resultados de un cuestionario, adaptado al idioma espa ol de su versión original en inglés del IPL y aplicado a una muestra de 98 gerentes, se le realizaron pruebas de confi abilidad. Esos resultados indican que el comportamiento "inspirar una visión compartida" se practica frecuentemente y que "desafiar los procesos" se emplea poco. También se observa que el número de subordinados y el tipo de empresa influyen en las prácticas de liderazgo de los gerentes.

Abstract: the illegal use of clenbuterol in feeding of cattle has caused outbreaks of food poisoning in humans that consume beef and internal organs. since 2007, with the modification of the ley federal de sanidad animal, the use of clenbuterol as growth promoter is penalized and coordinated actions are announced between the secretaria de salud (ssa) and the secretaria de agricultura, ganaderia, desarrollo rural, pesca y alimentacion (sagarpa) on concurrent issues. this study analyzed the implementation of the procedures in the public health sector, as well as the coordinated activities between ssa and sagarpa in queretaro and jalisco states in mexico. results indicate that a higher degree of collaboration between these two institutions is required in the exchange of information from sagarpa to ssa derived from penal procedures, as well as in the identification of improvement action procedures, thus optimizing the results achieved by both institutions in concurring actions related to sanitary surveillance of clenbuterol use.
