Incidentaloma Discoveries in the Course of Neuroimaging Research.

ABSTRACTAmong healthy volunteers in psychiatric brain functional magnetic resonance imaging (fMRI) research studies, the prevalence of incidentalomas can be as high as 34%, of which 10% show clinical significance. An incidentaloma is a lesion found by coincidence without clinical symptoms or suspicion. Like lesions and other types of accidental findings, it is found in healthy individuals recruited to take part in psychiatric studies. The prevalence of these accidental findings among specific psychiatric populations remains unknown. However, a precise understanding of cerebral neuroanatomy, neuroradiological expertise, and an appropriate choice of fMRI exploration sequences will increase the sensitivity of identifying these accidental findings and enable researchers to address their clinical relevance and nature. We present recommendations on how to appropriately inform patients or participants of the accidental findings. Additionally, we propose specific suggestions pertaining to the clinical research setting aimed for investigators and psychiatrists. Unlike current articles pertaining to incidentaloma, the current report provides a distinct focus on psychiatric issues and specific recommendations for studies involving psychiatric patients.

[Crossroads, 50 years of child care]. / La croisée des chemins, 50 ans de soins aux enfants.

INTRODUCTION: Through a journey in time, we propose to revisit the birth of the first mental health care settings for children with mental disorders affiliated with Université de Montréal, Quebec, Canada. METHODS: The main centers of child psychiatry affiliated with the Université de Montréal are presented with the outstanding figures of the time. RESULTS: Philosophical transitions and therapeutic paradigms are also briefly discussed. The creation of subspecialty clinics and training approved by the Royal College of Psychiatry of Child and Adolescent marked the contemporary era. CONCLUSION: The contribution to training medical students, residents and researchers in the field of Child and Adolescent Psychiatry reflects the important milestones since the foundation of the Université de Montréal Department of Psychiatry. So much achieved in half a century.

A review of obsessive-compulsive disorder in children and adolescents.

This article is a review of recent literature on obsessive-compulsive disorder in the pediatric population. Areas covered include: a brief historical perspective, clinical presentation in relation to symptoms found in different age groups, epidemiology, psychiatric comorbidity, etiology (with regards to genetics, neuroimaging, and familial factors), clinical course and prognosis, and treatment, with special emphasis on individual and family-based cognitive-behavioral therapy and psychopharmacology.
