SYNOPSIS. Dans un premier temps, le problème de l’extraction de motifs séquentiels peut sembler proche de celui de l’extraction de règles d’association. Ce rapprochement s’avère cependant très fragile en raison d’un élément clé qui est propre à l’extraction de motifs séquentiels : la temporalité. Cette notion permet à la fois de distinguer à l’intérieur des enregistrements un ordre d’apparition...

BACKGROUND Panic attacks may be a risk marker for a variety of psychological problems and are associated with increased impairment in a host of domains. However, previous studies have not investigated the role of physical illness in the panic attack-disability relations, which is striking due to findings that physical illness is linked to both panic attacks and disability. The present investiga...

Emerging evidence suggests that anxiety sensitivity (AS) predicts subsequent development of anxiety symptoms and panic attacks. However, evidence regarding whether AS serves as a premorbid risk factor for the development of clinical syndromes is lacking. The primary aim of the present study was to determine whether AS acts as a vulnerability factor in the pathogenesis of psychiatric diagnoses. ...

L’une des activités les plus importantes en biologie est l’analyse des données d’expression de gènes. Les biologistes espèrent ainsi mieux comprendre les fonctions des gènes et leurs interactions. Nous étudions dans cet article une technique permettant d’aider à l’analyse de ces données d’expression : l’extraction de concepts sous contraintes. Pour cela, nous proposons d’extraire des fermés sou...

Terrorism is a global issue and a constant international threat.

Résumé. La découverte d’informations cachées dans les bases de données multimédias est une tâche difficile à cause de leur structure complexe et à la subjectivité liée à leur interprétation. Face à cette situation, l’utilisation d’un index est primordiale. Un index multimédia permet de regrouper les données selon des critères de similarité. Nous proposons dans cet article d’apporter une amélior...

The purpose of the study was to contrast first panic attacks (PAs) of patients with panic disorder (PD) with vs. without agoraphobia and to explore differences between first PAs leading to the development of PD and those that remain isolated. Data were drawn from a community survey (N=2259 including 88 isolated PAs and 75 PD cases). An additional sample of 234 PD patients was recruited in a cli...

This systematic review aimed to examine the results of studies that have investigated the induction of panic attacks and/or the anxiogenic effect of the caffeine challenge test in patients with panic disorder. The literature search was performed in PubMed, Biblioteca Virtual em Saúde and the ISI Web of Knowledge. The words used for the search were caffeine, caffeine challenge test, panic disord...

Panic, when viewed ethologically, is not pathological in itself, it is rather an adaptation that evolved to facilitate escape in dangerous situations. Patients with panic disorder have panic with normal form, but the attacks occur in the absence of real danger. The agoraphobia syndrome can be understood as a related adaptation that is expected after repeated panic attacks. These hypotheses acco...
