Introduction: In the Surgical treatment of giant omphalocele and gastroschisis and recommended the complementary treatment with prosthetic synthetic patch in order to prevent the compartmental syndrome. But this prosthetic materials are get out seven a twelve days post surgery. Objectives: This study has the goal to determinate the usefulness of a porcine pericardium treated with 1 % glutaraldehyde , surgically applied on a defect in the abdominal wall. Matrial and method: The study was carry on in Experimental Surgery Unit at the National Child Hospital , we've had 30 rats Holtzmann with weights between 200 and 300 grams. The porcine pericardium sterile obtained was treated with 1% glutaraldehyde. The animals were anesthesied with ketamine 50 mg/ kg and Xilascina 12 mgs/kg IM Atropine 0.2 mgs/Kilo IM. Using sterile surgical technical a rectangular area of 3 x 1 centimeter of the abdomin...

Objective. To determine the clinical, epidemiological and pathological characteristics of lymphomas in patients of the National Institute of Child Health Breña between 2015-2019. Methods. A quantitative, observational, crosssectional, descriptive and retrospective study was carried out; corresponding to pediatric patients diagnosed with lymphoma between 2015 and 2019. The SPSS v24 program was used for the analysis. The quantitative variables were expressed in measures of central tendency and the qualitative ones in absolute and relative frequencies. Results. 43 cases were included, the average age was 7.2 years (1a – 16a), 72.1% (n = 31) were male. Among the most frequent symptoms are fever 51.2% (n = 22), weight loss 41.9% (n = 18) and fatigue 20.9% (n = 9) and among the prevalent signs, lymphadenopathy 83.7% (n = 36) and abdominal mass with 14% (n = 6). The most frequent location wa...

La hidatidosis pulmonar es una patología que tiene como agente etiológico a un parásito en forma de larvas de Echinococcus granulosus; esto constituye una zoonosis que tiene como reservorio a los herbívoros o al hombre. Se reportó el caso de un varón de 48 años con dolor en hemitórax derecho, disnea, tos, expectoración y fiebre. Al examen físico de radiografía de tórax y tomografía (murmullo vesicular y vibraciones vocales disminuidos en lóbulo medio de pulmón derecho) y a la percusión matidez; se encontró hallazgos anormales sugestivos de hidatidosis. En los exámenes del laboratorio se evidenció leucocitosis con desviación izquierda, PCR 145 mg/ml, VSG 85. El diagnóstico se basó en criterios clínicos, estudios de imagen, y el antecedente epidemiológico. Se procedió a la extracción quirúrgica del quiste. El diagnóstico se confirmó con el estudio de anatomía ...

Medulloblastomas are the most common malignant brain neoplasms in children. Immunohistochemical(IHC) markers can determine a molecular classification, using the markers GAB1, YAP1, β-catenin, P53, and Ki67. The classification of these neoplasms into molecular groups has proven to be clinically and therapeutically significant. The clinical outcomes of medulloblastoma include death, adverseeffects or conditions, and tumor recurrence. The objective of this research was to determine the individual association between the IHC markers used for molecular group classification and the clinical outcome in patients with medulloblastoma treated at the Instituto Nacional de Salud del Niño (INSN - National Institute of Child Health) during the period 2013–2022. The population consisted of 58 patients. The individual IHC expression of GAB1, YAP1, β-catenin, p53, and Ki67 in paraffin-embedded biops...
