++

Syndrome consisting of alopecia or hypotrichosis, oligophrenia, microcephaly, seizures, and mental retardation.

++

Alopecia-Epilepsy-Oligophrenia Syndrome; Alopecia-Mental Retardation-Epilepsy-Microcephaly Syndrome; Epilepsy-Oligophrenia Syndrome of Moynahan.

++

Three types of this disorder are suggested:

++

Type I: Total alopecia and mental retardation, the main features, in association with microcephaly

++

Type II: Subtotal alopecia and mental retardation with or without epilepsy

++

Type III: Subtotal alopecia and psychomotor retardation with microcephaly and epilepsy

++

First described in 1962 by E.J. Moynahan, an British dermatologist practicing in London.

++

The incidence remains unknown.

++

Familial with parental consanguinity; autosomal recessive trait.

++

Unknown.

++

Microcephaly, alopecia or hypertrichosis, and epilepsy (grand mal seizures).

++

Sparse or absent scalp hair, microcephaly, seizures, short stature; hypogonadism with late puberty. Poor musculature. Sometimes sensorineural deafness.

++

No literature on anesthesia in this condition. However, full neurologic history and examination, epileptic history, especially of control and medications, and associated anomalies resulting from microcephaly must be reviewed.

++

Epileptic control is essential; usual medications should be maintained until the morning of surgery wherever possible and appropriate nontriggering anesthetic agents used. Psychomotor retardation with poor speech skills may lead to a uncooperative patient.

++

Note potential for interaction with antiepileptic drugs. Chronic phenytoin administration increases nondepolarizing neuromuscular blocker requirements, produces gingival hyperplasia and bleeding, and may cause hepatic dysfunction. Ketamine, enflurane, and methohexital are relatively contraindicated. High concentration (greater than 5-6%) of sevoflurane at induction might trigger epilepsy.
