The 2',3'-cyclic nucleotide 3'-phosphodiesterase and oligodendrocyte lineage transcription factor 2 genes do not appear to be associated with schizophrenia in the Japanese population.

Several lines of evidence suggest that disturbance of myelin-related genes is associated with the etiology of schizophrenia. Recently, the 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) gene and the oligodendrocyte lineage transcription factor 2 (OLIG2) gene were reported to be related to the development of schizophrenia, based on the results of genetic association and microarray studies. In the present study, no significant association with schizophrenia was observed by single-marker or haplotype analysis for 6 tag SNPs of these genes (759 cases, 757 controls).

An association study between catechol-O-methyl transferase gene polymorphism and methamphetamine psychotic disorder.

Objective: A series of methamphetamine psychosis reveals two kinds of clinical courses of methamphetamine psychosis: transient type and prolonged type. Furthermore, paranoid psychosis sometimes recurs without methamphetamine reuse, referred to as spontaneous relapse. Dysfunction of central dopaminergic neurotransmission has been implicated in the pathogenesis of these psychiatric states.

Emergence agitation after sevoflurane versus propofol in pediatric patients.

Unlabelled: Sevoflurane may be associated with a high incidence of emergence agitation in preschool children. We tested the hypothesis that maintenance of anesthesia with propofol after sevoflurane induction would reduce the incidence of this excitatory behavior compared with continuing sevoflurane for maintenance. We conducted a randomized, single-blinded, two-period, cross-over study in 16 preschool age children undergoing repeated brief general anesthetics for eye examination.

Comparison of acceleromyography and electromyography in vecuronium-induced neuromuscular blockade with xenon or sevoflurane anesthesia.

Study Objectives: To compare acceleromyography (AMG) and electromyography (EMG) with xenon or sevoflurane anesthesia during vecuronium-induced neuromuscular blockade.

Design: Prospective randomized study.

Setting: University hospital.
