Piacenza, January 5 - Prosecutors are probing the death of an unborn baby shortly before a programmed caesarean delivery, media reported Tuesday. Investigations began after the father turned to police saying doctors in Piacenza had performed a successful clinical examination on his wife on December 31. The woman subsequently returned to the hospital after her baby stopped showing signs of life. The local authorities said in a statement that all the proper procedures had been followed during gestation and that the pregnancy had showed no particular risk factors. The incident comes as questions continue to be asked over the death of five women in the final stages of pregnancy in Italy in the last week. The health ministry has dispatched a task force of inspectors to probe the deaths. Initial reports suggest the hospital was not to blame in at least one case, involving a woman who died of cardiac arrest at Turin's Sant'Anna Hospital shortly after her daughter Elisa was still-born on December 26.
