Worming Cows?Peter Plate It has come to our attention that representatives from a pharmaceutical company have been visiting dairies in the area and taking bulk milk samples to test for Ostertagia (abomasal worm)antibodies. On producing a positive result, farmers have then been advised to worm their entireherd with an avermectin based pour-on and told that doing so could increase yield by two litres per It was Christmas in the cowshed cow per day.
Not a single cow could sleep We would like to take this opportunity to explain why taking such action based on such a test Every eye was tightly shut would be poor clinical practice based on bad science.
Trying not to peep First, it is important to understand a bit about the parasite. Ostertagia ostertagii is an abomasal roundworm, which follows a direct lifecycle between cattle and the pasture.

Microsoft word - el sÍndrome del diente fisurado.doc

Traducido del Texto "Endodontics" de Arnaldo Castellucci MD, DDS Vol. 1. Primera Ed. 2.004 Traducción: Dr. Carlos Heilborn. Odontólogo. Especialista en Endodoncia. Asunción - Paraguay EL SÍNDROME DEL DIENTE FISURADO Uziel Blumenkranz S. DDS Si uno considera las varias quejas de los pacientes con diferentes formas de patología pulpar, por ej. sensibilidad al frío en la hiperemia o sensibilidad al calor en las pulpitis; o de patología peri apical, por ej. dolor desencadenado por presión en una periodontitis o absceso, uno puede concluir que éstos no pueden coexistir en el mismo diente. Mientras el paciente puede manifestar que el diente es sensible al calor, frío y presión, esto se debe generalmente a la condensación de síntomas de odontalgias previas. Sin embargo, existe un caso en el cual estos tres síntomas pueden originarse y coexistir en un mismo diente. Esto se conoce como el "síndrome del diente fisurado". Introducción Hasta el año 1.964 se han sugerido muchos nombres para esta condición. Pero fue Cameron quien introdujo el término "síndrome del diente fisurado", agregando que "el factor más importante para el diagnóstico del diente fisurado es el conocimiento de que estas fisuras suceden". Aunque se han escrito muchos artículos sobre este tema desde entonces, muchos pacientes con este síndrome están sin diagnóstico. Además existe una confusión en la literatura dental al respecto de los dientes diagnosticados con el "síndrome del diente fisurado" y aquellos fracturados como consecuencia de accidentes de procedimientos. Las fracturas de la última categoría han sido denominadas Fracturas Apicales Inducidas por Williams y fracturas radiculares verticales, por otros. Mientras que en ambos casos el la consecuencia en el diente puede ser la misma, la etiología es diferente. También es un hecho que mientras que la profesión dental se valga principalmente de las evaluaciones radiográficas, este síndrome no puede ser fácilmente identificado. Las fisuras se producen de mesial a distal, donde las películas radiográficas son incapaces de capturarlas. Por tanto, más y más dientes serán víctimas del "síndrome del diente fisurado". Aún así, si se detectan pueden ser salvados. Los dientes fisurados son muy difíciles de diagnosticar, especialmente si el dentista no los está buscando. En muchos casos, debido a la ignorancia por parte del dentista, el paciente es tildado de "paranoico", y es enviado a su casa con una prescripción de tranquilizantes. Es notable que en su estudio Cameron reportó que un paciente aquejado del síndrome del diente fisurado estaba siendo medicado con Tegretol debido a una posible neuralgia trigeminal y para otro se estaba considerando cirugía cerebral. Los dientes fisurados son un estadio intermedio de una serie de eventos que, si no se reconocen y no se tratan, culminarán con la extracción del diente. El diagnóstico y tratamiento precoces a menudo pueden prevenir molestias innecesarias y tratamientos más invasivos. Definición El "Síndrome del Diente Fisurado" se caracteriza por una fractura incompleta de un diente posterior con pulpa vital, la cual incluye dentina y posiblemente la pulpa dental. En un intento de expandir el dominio del síndrome, deben incluirse también en esta definición los dientes fisurados con necrosis pulpar y/o abscesos dentoalveolares. Un diente se considera "fisurado" cuando los potenciales segmentos de la fractura se mantienen intactos por una porción del diente a través del cual la fractura aún no se ha extendido. La "fisura" se refiere a una disrupción o interrupción de la continuidad de la
