Introduction: CONGENITAL ANOMALIES (CAs) are a worldwide problem and an important cause of childhood death, chronic illness, and disability. They result from defective embryogenesis or intrinsic abnormalities in the development process and often lead to long-term disability, which may have significant impacts on individuals, families, health-care systems, and societies. The most common, severe CONGENITAL ANOMALIES include heart defects, neural tube defects and the Down syndrome. Although CONGENITAL ANOMALIES may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes. Some CONGENITAL ANOMALIES can be prevented,timely vaccination of the mother, adequate intake of folic acid or iodine through fortification of foods or supplementation during pregnancy, and adequate antenatal care are just 3 examples of primary preventive methods. Physicians involved in the provision of health care for children and adolescents, need a basic understanding of how to evaluate and when to refer children and adolescents with CONGENITAL ANOMALIES to the respective subspecialty. Therefore, the aim of this article is to review the incidence, and different patterns of birth defect or CONGENITAL ANOMALIES in several Eastern Mediterranean developing countries. Materials and Methods: In this study, the terms Birth Defects, CONGENITAL ANOMALIES and CONGENITAL Malformations are synonymous and have been used interchangeably throughout this article. Conclusion: This study provides useful information about the extent and range of CONGENITAL malformations diagnosed immediately after birth in infants and highlighted the prevalence and types of CONGENITAL malformations. Maternal vaccination, adequate intake of folic acid or iodine through fortification of main foods or supplements during pregnancy, and adequate prenatal care are just three examples of contraceptive methods.
