Predictors of Complicated Appendicitis with Evolution to Appendicular Peritonitis in Pediatric Patients.

Appendicitis is one of the most frequent surgical emergencies in pediatric surgery. Complicated appendicitis can evolve with appendicular peritonitis characterized by the diffusion of the pathological process to the peritoneal cavity, thus producing generalized or localized inflammation of the peritoneum. The capacity to anticipate the possibility of perforation in acute appendicitis can direct prompt management and lower morbidity.

Prediction of histopathological local staging by radiological findings and differential diagnosis overview in children with nephroblastoma.

Background: Nephroblastoma is the most common renal malignancy in children kidney. They are highly heterogeneous tumors with challenging imagistic and histopathological (HP) differential diagnosis. Imaging is critical for understanding local anatomy, staging and for planning surgical approach.
