Niveles de conocimiento y práctica sobre prevención en salud bucodental de padres cuyos hijos acuden a la Cátedra de Odontopediatría de la Facultad de Odontología de la Universidad Nacional de Asunción en el año 2009 / Levels of knowledge and practice of prevention in oral health of parents whose children attend the Department of Dentistry of the Fucultad of Dentistry, National University of Asunción in 2009

Los padres son los únicos responsables de la salud bucal de sus hijos durante le primeros años de vida, tienen la responsabilidad de inicia a sus hijos en las prácticas de higiene bucal, proporcionarle una dieta equilibrada para favorecer un desarrollo óptimo en todas las estructuras corporal y velar, con la ayuda de un profesional odontológico, por un desarrollo equilibrado de toda la estructura estogmatognática. Este estudio observacional descriptivo de corte transversal, tuvo como objetivo determinar el nivel de conocimiento y práctica sobre prevención en salud bucodental de padres cuyo hijos acudieron a la cátedra de odontopediatría de la Facultad de Odontología de la Universidad Nacional de Asunción durante el año 2009, para lo cual se realizó una encuesta sobre higiene bucal, dieta, Flúor, alimentos cariogénicos y erupción dentaria, que constituyeron las variables de interés. La muestra estuvo constituida por 152 sujetos de ambos sexos. Los resultados del estudio demostraron que un 78,9% de los padres encuestados posee conocimiento suficiente, frente a un 21,19% que posee conocimiento insuficiente

A soundscape study: What kinds of sounds can elderly people affected by dementia recollect?

In this study, the kinds of sounds recollected by elderly people with dementia were investigated as a first step towards improving their sound environment. Onomatopoeias were presented to elderly people as keys to recollecting sounds, and they told what they imagined from each onomatopoeia. The results are summarized as follows. (1) Generally speaking, sounds from nature, such as the songs of birds and the sound of rain were recollected easily from onomatopoeias, regardless of gender. (2) Sounds of kitchen work were recollected by women only. (3) Sounds from old routines were recollected clearly. (4) Sounds that elicited feelings of nostalgia were also recollected intensely from onomatopoeias. These results show that elderly people suffering from dementia are able to recollect the sounds that had once occupied very important parts of their lives. However, these sounds in themselves are not unusual sounds in their daily lives. This suggests the importance of soundscape design in daily life.

Use of polymerase chain reaction in the diagnosis of toxocariasis: an experimental study.

In this paper we report the usefulness of polymerase chain reaction technique in the diagnosis of visceral larva migrans in a mouse model. Liver samples obtained from two set of experimentally infected mice (10, 100, 1,000 and 10,000 embryonated Toxocara canis eggs per mouse) along with the eggs of T. canis, T. cati and Ascaris suum were included in this study. Polymerase chain reaction (PCR) was performed using Toxocara primers (SB12). The first PCR product electrophoresis revealed very thin positive bands or no bands in liver samples. However, on second PCR a clear-cut bands were observed. No positive band was shown by A. suum eggs. Our findings thus indicate the usefulness of PCR technic in the diagnosis of visceral larva migrans (VLM) in liver biopsy materials specifically by means of double PCR using the primer SB12.
