ABSTRACT
Objetivo . El propósito de este estudio fue comparar los cambios mediante tomografía computarizada de haz cónico en el posicionamiento condilar de pacientes Clase III antes y después de una osteotomía sagital bilateral de rama mandibular indicada para la retro- posición mandibular. Métodos . Se analizaron 30 pacientes, 16 mujeres y 14 hombres con rango de edad de 15 a 40 años y deformidad dentofacial Clase III no tratada que asistieron a consulta de diagnóstico en el periodo del año 2013 al 2016 en el Hospital Regional "General Ignacio Zaragoza" (CDMX, México), realizándoseles mediciones de la posición condilar en tres tiempos: prequirúrgico, intermedio (4 días posquirúrgico) y final (9 meses posquirúrgico), en dos planos: corte sagital y corte coronal. Resultados . No se observó diferencia significativa en los espacios anterior, central y posterior antes (2,56 ± 0,55 mm; 1,78 ± 0,48 mm; 1,92 ± 0,36 mm) y después (2,68 ± 0,51 mm; 1,87 ± 0,43 mm; 2,01 ± 0,37 mm), diferencia de medias -0,120; -0,085; -0,090 p =0,921; 0,948 y 0,778, respectivamente. Del mismo modo, en el corte coronal no se observan cambios significativos en los ángulos condilares derecho antes (68,25 ± 1,56°) y después (68,77 ± 1,63°) p =0,217; e izquierdo antes (68,92 ± 1,63°) y después (69,30 ± 2°) p =0,215. Conclusiones . La osteotomía sagital bilateral de rama mandibular en pacientes Clase III es una técnica quirúrgica que ofrece mínimas alteraciones condilares, pues mantiene una estabilidad condilar en el posoperatorio a 9 meses.
Objective. The purpose of this study was to compare the changes by conical beam com- puted tomography in the condylar positioning of Class III patients before and after a sagittal osteotomy of the bilateral mandibular ramus in Class III indicated for mandibu- lar retroposition. Methods. Thirty patients were analyzed, 16 women and 14 men with an age range of 15 to 40 years and untreated Class III dentofacial deformity who were attended by diagnostic consultation during the period from 2013 to 2016 at the "Gen eral Ignacio Zaragoza" Regional Hospital (CDMX, Mexico), performing measurements of the condylar position in three stages: presurgical, intermediate (4 days after surgery) and final (9 months after surgery), in two planes: sagittal section and coronal section. Re - sults. No significant difference was observed in the anterior, central and posterior spaces before (2.56 ± 0.55 mm; 1.78 ± 0.48 mm; 1.92 ± 0.36 mm) and after (2.68 ± 0.51 mm; 1.87 ± 0.43 mm; 2.01 ± 0.37 mm), mean difference -0.120; -0,085; -0.090 p =0.921; 0.948 and 0.778, respectively. Similarly, in the coronal section there are no significant changes in the right condylar angles before (68.25 ± 1.56 °) and after (68.77 ± 1.63°) p =0.217; and left before (68.92 ± 1.63°) and then (69.30 ± 2°) p =0.215. Conclusions. Sagittal osteotomy of the bilateral mandibular ramus in Class III patients is a surgical technique that offers minimal condylar alterations, since it maintains a condylar stability in the postoperative period at 9 months.
ABSTRACT
En el año 2001, se constituye el Instituto Pediátrico del Corazón (IPC) con el fin de integrar a cardiólogos pediátricos y cirujanos cardiacos en una unidad multidisciplinar dedicada a la atención integral del paciente con cardiopatía congénita. Esto incluye la atención a pacientes desde el periodo fetal hasta la edad adulta y requiere de una estrecha colaboración con intensivistas pediátricos, anestesiólogos, obstetras y cardiólogos de adultos. El crecimiento y la calidad de la actividad asistencial, investigadora y docente de esta unidad en los últimos años, la ha llevado a ser designada como unidad de referencia a nivel nacional (CSUR) para el tratamiento de neonatos y niños con cardiopatías congénitas así como para el tratamiento de la hipertensión pulmonar compleja (AU)
In the year 2001, the Pediatric Heart Institute (PHI) was formed in order to integrate pediatric cardiologists and heart surgeons into a multidisciplinary unit dedicated to the comprehensive care of the patient with congenital heart disease. This includes patient care from the fetal period up to the adult age and requires close collaboration by the pediatric intensive care physicians, anesthesiologists, adult cardiologist and obstetricians. The growth and quality of the care, investigator and teaching activity of this unit in recent years has led it to being designated as Reference Centers, Services and Units (CSUR by its acronym in Spanish) on the national level for the treatment of newborn and children with congenital heart disease and for the treatment of complex pulmonary hypertension (AU)

The purpose of this study was to determine the therapeutic efficacy of albendazole and praziquantel administration in the treatment of neurocysticercosis of the fourth ventricle. The authors report the results obtained in 10 patients with cystic neurocysticercosis of the fourth ventricle who were treated with albendazole at a dosage of 15 mg/kg/day for 2 weeks. Because of the failure of albendazole treatment, two of the patients received an additional course of praziquantel at a dosage of 100 mg/kg/day for 2 weeks. A total of 16 courses of albendazole and two courses of praziquantel were administered to the 10 patients. In eight patients (80%), there was complete disappearance of the cyst, in one other (10%) there was an important decrease in the size of the cyst, and in one (10%), no change was seen. None of the patients had complications during the follow-up period of between 6 and 26 months (average 15.7 months). The authors postulate that a regimen of albendazole is the treatment of choice for this type of neurocysticercosis, although praziquantel may also be useful.

Measles pneumonia is the most frequent complications associated with mortality in this infection. There are two types, one corresponds to the giant-cells pneumonia and the other one to lung superinfection after measles infection. The first one has been occurred in immunosuppressed patients, without rash. We reported a measles pneumonia case in a previously healthy adolescent girl who had a fatal pneumonia by giant cells demonstrated by open lung biopsy. The review of the literature showed that this is very unusual in normal population.

Changes in CT scan and NMR imaging findings are reported in a patient with cerebral radiation lesions affecting first the left and then the right frontal cerebral cortex. This case is exceptional since voluntarily and by necessity the radiation dose for an inextirpable frontal sinus tumor had been very high. As a result of this radiotherapy, a survival of about 10 years was obtained under good conditions, with cerebral lesions provoking relatively moderate functional consequences.
