Psychotic side effects of steroids have been observed at relatively high frequency if mild cases, such as euphoria, are included, while it has been said that incidences differ among kinds of steroids. We reported a case developing severe schizophrenia-like symptoms following the treatment with betamethasone although this drug is believed to be rarely involved in steroid-induced psychosis, and its psychotic side effects have been rarely reported. When betamethasone was administered for progressive peripheral facial paralysis at a mean daily dose of 7mg, psychotic symptoms appeared from the 15th treatment day. Psychosis began with interrupted appearance of excitation, autism, and misanthropia. Although the steroid was gradually decreased in dose because of abatement of facial paralysis, not only psychotic symptoms were aggravated, but also appeared hallucination. Thus the steroid was withdrawn before the scheduled date while its dose was gradually decreased, and haloperidol was administered. Psychotic symptoms were gradually eliminated and completely disappeared about 40 days after onset.

The objective of this study is to investigate the type, importance, and incidence of hereditary diseases in patients at the National Institute of Neurology and Neurosurgery in Mexico City. A review of 6,258 files indicated that hereditary diseases represent an important problem for the Institute. Of the diseases with the highest incidences, hereditary factors have an important role in seven (epilepsy, depression, facial palsy, schizophrenia, mental retardation, migraine, and Parkinson's disease). Diseases of known monogenic etiology represent 1.5% of all the cases.

To investigate molecular and clinical aspects of conotruncal anomaly face (CAF), we studied the correlation between deletion size and phenotype and the mode of inheritance in 183 conotruncal anomaly face syndrome (CAFS) patients. Hemizygosity for a region of 22ql1.2 was found in 180 (98%) of the patients with CAFS by fluorescence in situ hybridization (FISH) using the N25(D22S75) DiGeorge critical region (DGCR) probe. No hemizygosity was found in three (2%) of the patients with CAFS by FISH using nine DiGeorge critical region probes and a SD1OP1 probe (DGA II locus). None of these three patients had mental retardation and just one had nasal intonation, which was observed in almost all of the 180 CAFS patients who carried deletions (mental retardation, 92%; nasal voice, 88%). Nineteen of 143 families (13%) had familial CAFS and 16 affected parents (84%) were mothers. Although only two of the affected parents had cardiovascular anomalies, the deletion size in the 16 affected parents and their affected family members, who were studied by FISH analysis, was the same. It indicates that extragenic factors may play a role in the genesis of phenotypic variability, especially in patients with cardiovascular anomalies. No familial cases were found among CAFS patients with absent thymus/DiGeorge anomaly (DGA). Also, in all 18 CAFS patients with completely absent thymus/DGA and all 6 CAFS patients with schizophrenia, it was revealed that the deletion was longer distally. A study of the origin of the deletion using microsatellite analyses in 48 de novo patients showed that in 65% of CAFS patients it was maternal, while in 64% of DGA patients it was paternal. The findings of this study indicated that CAF was almost always associated with the deletion of 22ql1.2. As well as the major features of the syndrome, other notable extracardiac anomalies were found to be susceptibility to infection, schizophrenia, atrophy or dysmorphism of the brain, thrombocytopenia, short stature, facial palsy, anal atresia, and mild limb abnormalities.
