We sought to estimate the pooled current prevalence of posttraumatic stress disorder (PTSD) among rescue workers and to determine the variables implicated in the heterogeneity observed among the prevalences of individual studies. A systematic review covering studies reporting on the PTSD prevalence in rescue teams was conducted following four sequential(More)
Thirty years after creation of the posttraumatic stress disorder (PTSD) diagnosis, its literature could still benefit from standardization of traumatic events. The authors report the type and frequency of traumatic events found in the mainstream PTSD literature using a bibliometric approach, and propose a categorization based on the terms used for their(More)
A fair assessment of merit is needed for better resource allocation in the scientific community. We analyzed the performance of the institutional h-index in the case of Brazilian Psychiatry Post-graduation Programs. Traditional bibliometric indicators and the institutional h-index similarly ranked the programs, except for the Average Impact Factor. The(More)
PURPOSE No study has examined the impact of the comorbid Axis I conditions on the quality of life (QoL) of patients with a primary diagnosis of PTSD. Our goal was to investigate the influence of comorbid disorders on the QoL of treatment-seeking outpatients with PTSD. METHODS The diagnoses of PTSD and of the comorbid disorders were established using the(More)
The DSM-IV-TR postulates that PTSD symptoms are organized into 3 clusters. This assumption has been challenged by growing number of factor analytical studies, which tend to favor 4-factor, first-order models. Our objective was to investigate whether the clusters of PTSD symptoms identified in North American and European studies could be replicated in a(More)
BACKGROUND There is a dearth of literature dealing with the impact of the severity of posttraumatic symptoms and of comorbid mental disorders on the health-related quality of life (HRQOL) of victims of civilian violence with a primary diagnosis of PTSD. OBJECTIVES To investigate the influence of the severity of posttraumatic symptoms and of presence of(More)
BACKGROUND Tonic immobility is an involuntary motor and vocal inhibition reaction, considered the last-ditch response of the defensive cascade model. It is elicited in context of inescapable threat and perception of entrapment. Our aim was to investigate the association between different traumatic events and peritraumatic tonic immobility (PTI) in a(More)
Background: Prazosin is an antagonist of alpha-1 adrenergic receptor used to treat PTSD-related nightmares and insomnia. Although evidence suggests that it is also effective in the treatment of general symptoms of PTSD, its short half-life (2-3 hours) may limit its therapeutic effects. Objective: To describe four cases of patients with PTSD resistant to(More)
INTRODUCTION Conditional risk for PTSD is the risk of developing PTSD after exposure to traumatic events. This epidemiological study of the general urban population from the two largest cities in Brazil reports exposure to traumatic events; conditional risk for PTSD; and proportion/estimated number of PTSD cases secondary to each type of traumatic event.
