The diagnosis of Munchausen by proxy syndrome, a subtle form of child
abuse, is very difficult. One reason is a seemingly well caring ''idea
l'' mother who is mainly responsible for the fabricated illness of her
child, the other biologically and technically well trained medical do
ctors maltreating the children unwittingly Doctors are often separated
from each other by their subspecialities but nevertheless directly ap
proached by the mothers. The latter frequently have a medical educatio
n. A warning list of ''red flags'' of symptoms and clinical situations
should sensitise the pediatrician for artificial illnesses and enable
him to start diagnostic work-up early. One responsible doctor should
coordinate all activities. The crucial step is a separation of mother
and child, but a team approach involving child psychiatry, child wellf
are organisations and legal authorities is mandatory. Therapeutic opti
ons for the perpetrators are minimal. The prognosis is poor if such a
child is not separated from his family or retransferred too early. Res
earch to understand psychopathology and to develop new therapeutic opt
ions is needed.
