Se presenta un caso de Panencefalitis Esclerosante sub aguda post sarampión (PEESA), el primero en nuestro medio corroborado por técnicas de inmuno histoquímica y con el cual deseamos llamar la atención en varios puntos:

En este trabajo se reportan evidencias de los efectos de la hipoxia en la fisiopatología de la preeclampsia al demostrar: primero, que el aumento del receptor soluble-1 del VEGF es selectivo en células trofoblásticas (CT) en respuesta a valores bajos de oxígeno; segundo, que ese incremento está fuertemente ligado a la elevación del factor de transcripción HIF-2 alfa en las células trofoblásticas, y tercero, que las CT, fibroblastos de las vellocidades (FV) y endoteliales de vena umbilical (HUVEC) de placentas preeclámpticas son más sensibles a la respuesta hipóxica que las de otro origen. Finalmente, la elevación del receptor soluble sVEGFR-1 en CT en respuesta a HIF-2 alfa puede explicar un estado antiangiogénico que lleva a la remodelación deficiente de la vasculatura que se encuentra en la preeclampsia.

Introduction: the cardiac syndrome is the main cause of morbidty and mortality in Chagas disease, and its pathogenesis appears to be related to abnormalities of the autonomous nervous system which affect cardiovascular physiology. Objectives: to compare the values of heart rate ,blood pressure and electrocardiographic (EKG) abnormalities of the infected population with those of the control population. Materials and Methods: this is an analytic, observational, cross sectional study made in the valley of Vítor, Arequipa, from 2004 to 2005. Volunteers over 15 yearse of age ere studied: 25 T. cruzi seropositive an 50 T. cruzi seronegative persons. Examinations including heart rate, blood pressure and standard 12-lead EDGs were performed, comparing the results between the groups. Results: heart rate and blood pressure values were similar between seropositiv...
