Revisión sistemática sobre los modelos y protocolos de seguridad para la reapertura de colegios en pandemia por COVID-19. Objetivo: Determinar los resultados y clasificar la especificación técnica y metodológica de los modelos y protocolos de seguridad para la reapertura de los colegios. Métodos: Se realizó una revisión sistemática en base a la declaración PRISMA 2020 y utilizamos Pubmed, Scopus, Web of Science, Embase, CINAHL y Tripdatabase para la información bibliográfica. Se incluyó estudios transversales, cohortes, casos control y ensayos comunitarios sin limitación referida al idioma. En el desenlace se describieron los modelos y protocolos de seguridad para la reapertura de colegios en pandemia por COVID-19 y utilizamos el Newcastle Ottawa Scale (NOS) y NOS modificada para el análisis de riesgo de sesgo. Resultados: De 27 estudios que pasaron a la fase de selección...

This is a newborn in the department of San Martín, who presented gastroschisis and was treated immediately with hydration, parenteral nutrition, decompression of the hollow viscera with aspiration and surgical technique, using a blood bag as a protector to then proceed to the continuous taxia and the daily washes; with good evolution and total suture on the seventh day after the operation.

Crohn disease is of immunological origin, in which an inflammatory condition occurs that can be located anywhere in the intestine, especially in the ileocecal part. It is usually characterized by diarrhea and pain with weight loss. The present case is of a 15-year-old girl who abruptly debuts with abdominal right iliac fossa (RIF) pain, which suggests an appendicular condition, so she underwent surgery. In later days, he presented persistent vomiting, suspected of an obstructive condition. A second surgical intervention shows an inflammatory condition at the ileocecal level, so a colostomy and ileostomy are performed. Biopsy showed lesions consistent with Crohn's disease. Treatment with mesalazine and azathioprine was performed, achieving a remission of the picture. Six months later an anastomosis was performed with a favorable evolution of the patient.
