ABSTRACT
Fundamento: El laboratorio dental es una fuente potencial de contaminación cruzada. Este trabajo busca evaluar su control en Galicia. Material y métodos: Entrevistas telefónicas aleatorias y voluntarias hasta completar 149 cuestionarios. Las variables se describen mediante porcentajes o medias y desviaciones típicas. Se realiza análisis bivariante empleando ji cuadrado. Resultados: Participaron mayoritariamente varones (68,5%), de mediana edad (media=45,7; DE=9,8) con 20,8 (DE=10,5) años de ejercicio en laboratorios urbanos medianos (58,4%), que cuentan mayoritariamente con protocolo escrito (57,7%) y que identifican mayor riesgo al recibir trabajos (80,6%). El 55,0% (significativamente hombres de mayor edad) no asegura la desinfección de los trabajos. La mayoría usa guantes (62,4%), sobre todo jóvenes en laboratorios grandes. Un 55,7% está vacunado frente a hepatitis B. Una minoría (22,0%) ha recibido formación en control de contaminación cruzada. Conclusiones: Las prácticas de control de contaminación cruzada se encuentran por debajo de los estándares recomendados, con un importante déficit de formación y protocolos
Background: Dental laboratories are a potential source of cross-contamination. This study aims to assess its control in Galicia. Methods: Voluntary random telephone interviews resulted in 149 completed questionnaires. The variables are described by percentages or means and standar deviations. A bivariate analysis was undertaken using the Chi square test. Results: Participants were mostly middle-age (mean=45.7, SD=9.8) males (68.5%) with 20.8 (SD=10.5) years of professional experience in middle-size urban (58.4%) laboratories, who identified a higher risk when receiving items from the clinic (80.6%). Most technicians (57.7%) have a written protocol. Many (55.0%), significantly older males, do not check for item disinfection. Most technicians use gloves (62.4%) particularly younger staff at larger laboratories. Fifty-five point seven percent had been vaccinated against hepatitis B. Only 22.0% of technicians reported receiving training in cross-contamination control. Conclusions: Identified cross-infection control practices are below standards, and lack of training and protocols are a matter for concern

Eight children with arteriovenous malformations of the gastrointestinal tract were studied during a two year period (1989-1993). The main localization of the arteriovenous malformations were: ascending colon (five cases), descending colon (five cases), terminal ileum (three cases), rectum and sigmoid (three cases). Diagnosis approach was made with colonoscopy and arteriography. Surgical resection of the affected segments was the therapeutical procedure in seven of the eight cases.

We studied 40 children with recurrent abdominal pain during a period of six months (january to june 1993) entered at the gastroenterology service of the Instituto Nacional de Pediatria in México City. In all of then we performed in all of them an upper gastrointestinal endoscopy with 3 biopsies from gastric mucosa (antrum) for histological examination and urease tests. We also did an ELISA test looking for an H. Pylori specific serum IgG response. Our control group were 40 healthy children in whom we did only the ELISA test. We did not find any statistics differences between the histologic findings (gold standard) and the urease and ELISA tests. With IgG antibodies prevalence for H. Pylori in children with recurrent abdominal pain were 57% in contrast with our control group in whom the prevalence was 5%.

Se presentan ocho niños con diagnóstico de malformación arteriovenosa del intestino atendidos en el servicio de gastroenterología del Instituto Nacional de Pediatria durante el período de 1989 a 1993. Las malformaciones arteriovenosas (MAV) se localizaron con mayor frecuencia a nivel del colon ascendente (5 casos), descendente (5 casos), ileon terminal (3 casos), rectosigmoides (3 casos). La colonoscopía y arteriografía selectiva fueron procedimientos que permitieron el diagnóstico preoperatorio. La resección del segmento afectado fue el procedimiento terapéutico de elección en siete de los ocho casos

Se estudiaron 40 niños con dolor abdominal recurrente, que acudieron al servicio de gastroenterología del Instituto Nacional de Pediatría de la ciudad de México durante un período de 6 meses, de enero a junio de 1993. A todos los niños se les efectuó biopsia de estómago (antro) para histologia y prueba de ureasa rápida. Asimismo, se practicó determinación de anticuerpos IgG mediante la técnica de ELISA. El grupo control estuvo integrado por 40 niños sanos, esto es, sin manifestación ni evidencia de enfermedad gastrointestinal alguna y a los que se les realizó únicamente determinación de anticuerpos. No hubo diferencias estadisticamente significativas al comparar el estudio histológico (estándar de oro) con la prueba de ureasa rápida y ls determinación de anticuerpos por la técnica de ELISA. La prevalencia de anticuerpos IgG para helicobacter Pylori en problación con dolor abdominal fue de 57 por ciento mientras que en población sana fue de 5 por ciento.
