Objectives To examine the transfer of knowledge in psychiatry, longitudinally, over more than 35 years, through the 4 editions of the manual "Psychiatrie clinique" published in Quebec, thanks to the initiative of the publication directors affiliated with the Institut universitaire en santé mentale de Montréal (formerly the Louis-H. Lafontaine Hospital). Our hypothesis is that the evolution of the content and form of such a manual reflects an evolution of knowledge in psychiatry with a naturally educational vocation which of what must be known and applicable in the discipline.

Purpose: To describe long term clinical and functional outcomes of schizophrenia in a developed country.
Method: Long term longitudinal study of clinical and functional outcomes of incidence cohort of all consecutive admissions for a first hospitalization for schizophrenia between 1983 and 1987 in Montreal, Canada (n = 142). Data collection was conducted at admission, 5 years, 10-16 years and 27-31 years follow-up by reviewing hospital charts and government linked health administrative databases.

Schizophrenia is a severe psychiatric disorder characterized by important cognitive deficits, which ultimately compromise the patients' ability to make optimal decisions. Unfortunately, the neurobiological bases of impaired reward-related decision-making in schizophrenia have rarely been studied. The objective of this study is to examine the neural mechanisms involved in reward-related decision-making in schizophrenia, using functional magnetic resonance imaging (fMRI).

While clozapine is the gold-standard medication for this complex population, many will not respond to this molecule. For these ultra-resistant patients, limited options are available.
View Article and Find Full Text PDFSchizophrenia is a chronic and severe mental illness that poses significant challenges. While many pharmacological and psychosocial interventions are available, many treatment-resistant schizophrenia patients continue to suffer from persistent psychotic symptoms, notably auditory verbal hallucinations (AVH), which are highly disabling. This unmet clinical need requires new innovative treatment options.

We recruited 23 patients without and 24 patients with (SCZ+V) a history of violent behaviors, as well as 22 healthy non-violent men. Participants were administered an affective (angry-neutral faces) Go/NoGo task while undergoing functional magnetic resonance imaging.

Schizophrenia smokers, compared to their counterparts with no comorbid psychiatric disorder, are largely unaware and indifferent to the long-term negative consequences of cigarette smoking. The objective of this study was to determine, for the first time, if these meta-cognitive deficits are associated with neuro-functional alterations in schizophrenia smokers.

Objectives: To assess the effectiveness of exercise on pain, disability, function, patient satisfaction, quality of life (QoL) and global perceived effect (GPE) in adults with NP.
Methods: We searched computerised databases up to May 2014 for randomized controlled trials (RCTs) comparing exercise to a control in adults with NP with/without cervicogenic headache (CGH) or radiculopathy.
Background: Highly prevalent in schizophrenia, tobacco smoking substantially increases the risk of cardiac-related death. Compared to the general population, tobacco smoking cessation rates are lower in schizophrenia. Unfortunately, the reasons for these low cessation rates remain poorly understood.

Growing evidence suggests that cannabis abuse/dependence is paradoxically associated with better cognition in schizophrenia. Accordingly, we performed a functional magnetic resonance imaging (fMRI) study of visuospatial abilities in 14 schizophrenia patients with cannabis abuse (DD), 14 nonabusing schizophrenia patients (SCZ), and 21 healthy controls (HCs). Participants performed a mental rotation task while being scanned.

Despite this, the reasons for cannabis abuse remain elusive, but emotions may play a critical role in this comorbidity. Accordingly, we performed a functional magnetic resonance imaging study of emotional memory in schizophrenia patients with cannabis abuse (dual-diagnosis, DD).

We, an invited panel of experts led by a working group of 3, critically examined the evidence and our collective experience regarding the effectiveness, tolerability and safety of ziprasidone across its clinical uses. There was no opportunity for manufacturer input into the content of the review.

However, the results have not been consistent and the mechanisms underlying this effect have not been elucidated. Thus, the purpose of the present study was to evaluate verbal and nonverbal cognition (using visuospatial processing tests) in patients treated with clozapine (initially treatment resistant) and those treated with other second-generation antipsychotics, relative healthy control subjects.

However, neuronal correlates of change related to food information processing have not been investigated with these medications. We studied the effect of a pharmacological manipulation with an antipsychotic known to cause weight gain on metabolites, cognitive tasks and neural correlates related to food regulation.

Methods: Here we used functional magnetic resonance imaging (fMRI) to assess brain activity in response to food cues and neutral stimuli in twenty patients with schizophrenia and eleven healthy individuals. In addition to clinical and dietary habits assessments, we collected, in patients, measurements of fasting glucose, ghrelin, leptin, insulin, prolactin and lipids blood concentration and we correlated the cerebral activity with clinical and metabolic measures.
This article examines the adoption in Québec of the evidence-based practice, Integrated Psychological Treatment (IPT) of people with schizophrenia and the longevity of this practice within nine clinical milieus in a context of transformation of services. A team of researchers of the Centre de recherche Fernand Seguin has closely followed the implementation and the maintenance of the IPT in nine clinical milieus. More specifically, this article presents the factors that have contributed, on a five year period, to the maintenance (or not) of the IPT in these settings.

There are no recent North American studies on the long-term outcome of first-episode schizophrenia to clarify if these beliefs are myths or reality. Our study describes the long-term outcome (10 to 16 years) of a first-episode schizophrenia incidence cohort (n = 142) in a Canadian urban centre between 1983 and 1999.

Human exposure to bisphenol A (BPA) has recently received special attention. It has been shown that exposure to BPA may occur through the consumption of beverages or foods that have been in contact with polycarbonate (PC) plastic containers or epoxy resins in food packaging. A BPA migration study was conducted using a variety of plastic containers, including polycarbonate baby bottles, non-PC baby bottles, baby bottle liners, and reusable PC drinking bottles.

The authors realized that various programs have multiplied in the course of the last decade and many have shown benefits in comparison with the usual treatments delivered in general psychiatry. Thus these programs are composed of the following elements : family intervention, intensive community treatment, employment support, cognitive behavioural therapy and social skills training.
