Diagnostic value of hemoglobin concentration in identifying Meckel's diverticulum in pediatric lower gastrointestinal bleeding.

Purpose: To assess the diagnostic performance of hemoglobin concentration for Meckel's diverticulum (MD) and evaluate if hemoglobin levels could be useful in the surgical decision-making process of children with lower gastrointestinal bleeding (LGIB).

Methods: Retrospective cohort study of children with LGIB attending the emergency department between 2011 and 2021. Episodes of LGIB were divided into two groups: MeckD (MD diagnosed by surgery) and non-MeckD.

Role of Intraluminal Esophageal Impedance Baseline in the Diagnosis of Esophagitis in Children.

 Low values of esophageal impedance baseline (EIB) have been related to esophagitis. The aim of this study was to evaluate the diagnostic performance of EIB for erosive esophagitis (ErE) and histological esophagitis (HiE) in children studied for gastroesophageal reflux.  Children who underwent esophageal multichannel intraluminal impedance-pH monitoring (MII-pH) and upper-endoscopy with esophageal biopsies were studied retrospectively.

Surgical Findings in Transfusion-Associated Necrotizing Enterocolitis.

Introduction The extent of intestinal damage in transfusion-associated necrotizing enterocolitis (TNEC) has been scarcely studied. The aim of this investigation was to study surgical findings in TNEC and determine their severity considering the extent of the disease and risk of bowel perforation. Materials and Methods Neonates who required surgical treatment for necrotizing enterocolitis (NEC) were studied retrospectively.

Could clinical scores guide the surgical treatment of necrotizing enterocolitis?

Purpose: Test the diagnostic reliability of the score for neonatal acute physiology-perinatal extension-II (SNAPPE-II) and the metabolic derangement acuity score (MDAS) as predictors of surgery in patients with necrotizing enterocolitis (NEC).

Methods: The SNAPPE-II and the MDAS were applied to 99 patients with NEC. Both the scores were calculated at the moment of diagnosis (T(0)) and when surgical assessment was required (T(1)).

Diaphragmatic avulsion with chance fracture: a rare association in the seat belt syndrome.

Traumatic diaphragmatic injuries are uncommon in children. Chance fractures are typical in adults who had motor vehicle accidents but infrequent in children. The seat belt syndrome is characterized by a spectrum of injuries caused by the compression of the abdomen by the seat belt.
