Síndrome de Münchausen by proxy: enfoque forense / Munchausen syndrome by proxy: forensic approach

El síndrome de Münchausen by proxy es una forma de maltrato infantil cuyas consecuencias pueden ser tan graves como la muerte del niño, víctima de enfermedades ficticias provocadas por un cuidador del que es muy dificil sospechar.

Considering suffocatory abuse and Munchausen by proxy in the evaluation of children experiencing apparent life-threatening events and sudden infant death syndrome.

This study describes 138 young children admitted to the hospital over a 23 year period for recurrent apparent life threatening events (ALTEs), unexplained deaths, or with Sudden Infant Death Syndrome (SIDS)-related diagnoses. In examining the potential for suffocatory abuse in living children, we utilized characteristics in the literature that distinguish SIDS or ALTEs due to natural disease states from abuse. Findings demonstrate a co-occurrence of risk factors that raise suspicions of suffocatory abuse or Munchausen by Proxy. Of the 35 children who died, SIDS was the presumed clinical diagnosis at the time of death in 71 % of the cases. Comprehensive chart review and autopsy findings revealed a non-SIDS diagnosis in 54% and confirmed or suspicious child abuse in 37% of these deaths. Reports to Child Protective Services were made in 6% of cases. Recommendations for assessment of children including attention to risk indicators, involvement of child protection teams, mandatory autopsies, and eath scene investigations are offered.

Clinical and toxicological findings in two young siblings and autopsy findings in one sibling with multiple hospital admissions resulting in death. Evidence suggesting Munchausen syndrome by proxy.

A 15-month-old girl underwent several emergency department (ED) visits and two admissions for parent-reported histories of ingestions, apnea, and seizures. She was initially admitted following reports of several unusual episodes of syncope accompanied by convulsive movements and was discharged on mephobarbital with a diagnosis of atypical seizure disorder. The day after discharge, she was brought to the ED in cardiopulmonary arrest and was resuscitated after a prolonged period. She was declared brain dead 2 days later. Ante- and postmortem toxicology produced several inconclusive findings, none of which explained death. Autopsy findings, including neuropathology, failed to demonstrate any significant disease processes. Approximately 3 months later, a 4-month-old female sibling was brought to the ED with a parent-reported history of apnea and seizures similar to the deceased child. A stool specimen obtained 2 days after admission contained numerous tiny seeds, which were found by gas chromatography-mass spectrometry analysis to contain lorazepam and temazepam. The role of these benzodiazepines in the apnea episodes in this infant was unknown, but the presence of the seeds in such a young infant coupled with the parent's aberrant behavior, led to the tentative diagnosis of Munchausen syndrome by proxy. This diagnosis was strengthened when results from these studies persuaded legal authorities to remove the surviving sibling from the parents, resulting in an asymptomatic recovery.

Pediatric abuse. New patterns of injury.

The spectrum of abusive symptomatology has continued to expand since the initial report of the battered child syndrome. Many of these abused children present to the ED without a history of trauma. The ED physician must be aware of the range of clinical signs and symptoms to recognize and treat these children.

Munchausen syndrome by proxy.

Munchausen syndrome by proxy may result in a child suffering significant morbidity and mortality either from a parent or carer or as a result of unnecessary hospital admissions, investigations and treatment. It should therefore be considered in the differential diagnosis of any child with signs or symptoms that remain unexplained after standard investigations or are unresponsive to treatment.

Co-morbidity associated with fabricated illness (Munchausen syndrome by proxy).

Fifty six children who had been victims of fabricated illnesses and 82 of their 103 siblings were studied. In addition to the index fabrication, 64% of index children had had other illnesses fabricated by their mothers. Twenty nine per cent of the index children had a history of failure to thrive and 29% a history of non-accidental injury, inappropriate medication, or neglect. Seventy three per cent of the index children had been affected by at least one of these additional problems. Eleven per cent of the siblings had died in early childhood, the cause of death not being identified. Thirty nine per cent of siblings themselves had had illnesses fabricated by their mothers, and 17% had been affected by either failure to thrive, non-accidental injury, inappropriate medication, or neglect.
