Abstract [ntroductiO!I and Aim of Work INTRODUCTION AND AIM OF WORK Chronic illness and congenital malformations may cause growth retardation. Approximately 8 in every 1000 livebirtbs will have some form of congenital heart disease (Gersony, 1992). .6 Children with mild congenital cardiac abnormalities tend to grow normally. Those with more severe malformations frequently have evidence of serious growth abnormality. Gro’Wth retardation is most severe among those with large left to right shunts causing heart failure. Cyanosis tends to produce a rather parallel retardation of both height and weight while heart failure tends to cause a great retardation of weight than height (Rosenthal, 1993). Rheumatic fever is the most frequent cause of heart disease in the 5 to 13 years old group, cau:;ing 25% to 40% of aU hospital admi>sions in developing countries. The estimated prevalence in 1986 of chronic rheumatic heart disease is 7 per 1000 persons of all ages (Hurst, 1990). In Egypt, rheumatic heart disease is still the predominant form of heart disease in children (E!-Sherief, 1978) with a prevalence of 3.6-3.9 per thousand (Tav.:fique et al., 1988 and Mahfouz et a!., 1989). It was reported that the maximum age incidence was between 4 and 12 years in the majority of cases (Kassem et a!., 1982). 1 |
