There were no signs of perianal erythema. After the parents told of increased regurgitation, the anti H2 antagonist was replaced by a proton pump inhibitor PPI which was administered by the attending pediatrician through house calls. This was done despite the mother's comment that it was not advisable to administer proton pump inhibitors to children under 1 year of age.
Durante el tercer control, a los 2 meses y 15 días de edad, el paciente persiste con deposiciones con moco, aunque sin sangre y eritema perianal, relatan un aumento en las regurgitaciones, y el cambio del antagonista anti-H2 a inhibidor de bomba de protones IBP, implementado por el pediatra tratante extrainstitucional, a pesar de haberle comentado a la mamá que no era aconsejable instaurar IBP en niños menores de 1 año de edad.
