Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...
Background: Pesticides are chemical compounds used against vectors of human and animal diseases as well as plant pests. This study was undertaken to assess pulmonary reactions, if any, associated with occupational exposure to pesticides. Methods: This was a cross sectional analytical study in which a group of 86 exposed (employees of a pesticide producing company) and 75 unexposed referent sub...
