18q Deletion Syndrome-Associated Schizophrenia: A Case Report.

Introduction: 18q deletion syndrome is a rare genetic disorder characterized by various neurodevelopmental anomalies and medical issues. Although the occurrence of psychosis has been reported in a small number of cases, details regarding the nature of such symptoms and their response to treatment have not been described.

Case Presentation: We describe a 31-year-old male with a history of speech delays, autistic features, a tethered spinal cord, bilateral vertical talus, subaortic stenosis and aortic regurgitation, recurrent otitis media, mild hearing loss, and hypospadias, who experienced a first episode of psychosis in his late 20s.

Whole-genome sequencing analysis of clozapine-induced myocarditis.

One of the concerns limiting the use of clozapine in schizophrenia treatment is the risk of rare but potentially fatal myocarditis. Our previous genome-wide association study and human leucocyte antigen analyses identified putative loci associated with clozapine-induced myocarditis. However, the contribution of DNA variation in cytochrome P450 genes, copy number variants and rare deleterious variants have not been investigated.

The Coordinators of Psychiatric Education (COPE) Residency In-Training Exam: a preliminary psychometric assessment.

Objective: The Coordinators of Psychiatric Education (COPE) Residency In-Training Exam is a formative exam for Canadian psychiatric residents that was reconstructed using assessment best practices. An assessment of psychometric properties was subsequently performed on the exam to ensure preliminary validity and reliability.

Methods: An exam blueprint was developed based on the 2007 Royal College objectives for psychiatric training.

Cue-induced brain activity in pathological gamblers.

Background: Previous studies using functional magnetic resonance imaging (fMRI) have identified differential brain activity in healthy subjects performing gambling tasks and in pathological gambling (PG) subjects when exposed to motivational and emotional predecessors for gambling as well as during gambling or response inhibition tasks. The goal of the present study was to determine if PG subjects exhibit differential brain activity when exposed to visual gambling cues.

Methods: Ten male DSM-IV-TR PG subjects and 10 matched healthy control subjects underwent fMRI during visual presentations of gambling-related video alternating with video of nature scenes.
