ABSTRACT
PURPOSE: The aim of this study was to describe a surgical technique that can be used to solve dentofacial deformities associated with narrow interradicular spaces of the anterior teeth of the maxilla and inadequate overbite/overjet seen in hand-articulated models. This is presented here as an alternative to segmentation of the maxilla in Le Fort I osteotomy. METHODS: Six patients with dentofacial deformities (classes II and III malocclusions) had Le Fort I osteotomy accompanied by buccal alveolar corticotomies of the maxilla. During the immediate postoperative period, elastic forces were applied to mobilize the anterior dentoalveolar segments until the planned overjet/overbite was observed. RESULTS: All patients reached the desired occlusion approximately 1 month after the surgical procedure. Pulp vitality of the teeth adjacent to the corticotomies was not compromised. CONCLUSIONS: The clinical results obtained confirm the technique as a safe and reliable alternative to segmentation of the maxilla in orthognathic surgery.

There are 2 types of distraction devices for mandibular distraction: buried and external. The advantage of buried devices is the stability, but the difficulty in removing the screws is the greatest disadvantage. To resolve this problem, an osteosynthesis screw (Fariña Screw) has been designed, which greatly facilitates its removal when buried distractors are used.

Se informa de 103 casos de dermatofibroma diagnósticados en el Departamento de Anatomía Patológica del Hospital General de Zona Núm 14 del Instituto Mexicano del Seguro Social en Guadalajara, Jalisco, estudiados en el periodo comprendido entre 1986 y 1995. Los datos obtenidos fueron analizados estadísticamente y se consideraron porcentajes, tasas, proporciones, media y desviación estándar. El tumor afectó principalmente a mujeres jovenes (71..8 por ciento), la edad promedio fue de 35 años; en 65.8 por ciento se localizó en extremidades y su prevalencia fue 2.66 por 100,000 derechohabientes

El presente estudio tiene como objetivo evaluar el impacto del "Programa de prevención y control de la enfermedad diarreica" en la demanda de servicios de hospitalización por diarrea, mediante el uso temprano de sales de hidratación oral y el incremento del estado nutricional a través de la promoción de la lactancia materna. En 11 años de estudio se logró disminuir la tasa de egresos hospitalarios de 3.2 en 1984 a 0.16 en 1994 por cada 1000 usuarios y una disminución del costo de la atención médica por este concepto de N$2'133,312.00 en 1993
