      Chukwu, J; Cunney, R; Molloy, E (Irish Medical Journal, 2014-09)
      Congenital Diaphragmatic Hernia (CDH) is a rare congenital disorder as a result of deficient development of the diaphragm with resultant herniation of abdominal viscera into the thoracic cavity, mal-development of the alveoli and pulmonary vessels 1,2 . The incidence of CDH â ranges from 1 in 2,000 to 1 in 15,000 births 3 . Due to the legislation in Ireland against termination of pregnancy it was suggested that there may be an increased incidence of CDH. There is no mandatory reporting of CDH cases in the Republic of Ireland (ROI) and Northern Ireland (NI). Voluntary case reporting to the Irish Paediatric Surveillance Unit (IPSU) started in January 2010.
