Immediate Results of the Use of Split-Thickness Skin Autografts With and Without Acellular Dermal Matrix in Patients with Burns: A Comparative Study in a Colombian Population.

Dermal substitutes have become fundamental tools for covering skin defects, most recently with biological subtypes such as glycerolized acellular dermal matrix (GADM). However, literature regarding this matter is scarce in Latin America and Colombia. In this descriptive observational study, we compared the use of partial skin autografts (PSA) combined with GADM and autografts without GADM.

Bronchodilator Response in FEF for the Diagnosis of Asthma in Children.

Background: Spirometry tests with a bronchodilator response (BDR) in FEV a methacholine concentration that produces a 20% drop in FEV (PC) ≤ 2 mg/mL, and a positive exercise test have high specificity for the diagnosis of asthma in children. However, the value of forced expiratory flow during the middle half of the FVC maneuver (FEF) in spirometry has been questioned. The objective of this study was to relate the BDR in FEF of spirometry tests with normal FEV and FEV/FVC to airway hyper-responsiveness (AHR) to methacholine or exercise in children age 5-15 y with clinical suspicion of asthma.

Venous-arterial CO difference in children with sepsis and its correlation with myocardial dysfunction.

This study aimed to determine the association between venous-arterial CO difference (Pv-aCO) and clinical outcomes of interest in children with severe sepsis and septic shock. An analytical observational study of a prospective cohort was conducted. The study was carried out from January 2015 to January 2018 in the pediatric intensive care unit of a referral hospital.
