Effect of zinc versus vitamin A supplementation on pediatric patients with community-acquired pneumonia.

Community-acquired pneumonia (CAP) is one of the most common infectious diseases affecting the respiratory tract and is responsible for a high mortality rate in children less than 5 years of age. The mortality rate due to CAP is much higher in low/middle-income countries than in high-income countries due to malnutrition and different micronutrient deficiencies that weaken the immune system. The aim of this study was to compare the effects of zinc and vitamin A, as two elements of micronutrient agents, on the recovery rate of children suffering from CAP aged from 6 months to 5 years.

Balloon Tamponade for the Management of Gastrointestinal Bleeding.

Background: Acute gastrointestinal bleeding is a potentially life-threatening condition that requires rapid intervention. In critically ill patients who are refractory to other therapies, balloon tamponade devices can be lifesaving.

Objective: We provide a review of balloon tamponade devices for gastric and esophageal variceal bleeding for emergency clinicians.
