Munchausen's syndrome by proxy Illness or injury in a child caused by a parent or other person in charge who purports the disorders to be spontaneous. The child is commonly brought, often repeatedly, for medical attention and, if suspicion is raised, any responsibility for the child's medical condition is strenuously denied. Separation from the parent or person in loco parentis leads to recovery of the child's disorder. The commonest caused conditions are seizures, rashes, apparent respiratory failure, rashes, bleeding, diarrhoea and vomiting and near-coma. All of these are brought about by such means as partial suffocation, pressure on the neck, the administration of drugs, poisoning, the application of blood or the use of anticoagulants such as warfarin rat poison. Covert closed-circuit TV monitoring has been used to detect the crime.
