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)
The selective serotonin reuptake inhibitors (SSRIs) are considered the first-line pharmacological treatment for PTSD. However, even when treated with this class of drugs, response rates rarely exceed 60% and less than 20-30% of the patients achieve full remission. The aim of this study was to address this limitation by systematically reviewing the options(More)
This systematic review aims to investigate neurobiological changes related to cognitive-behavioral therapy (CBT) in anxiety disorders detected through neuroimaging techniques and to identify predictors of response to treatment. Cognitive-behavioral therapy modified the neural circuits involved in the regulation of negative emotions and fear extinction in(More)
Tonic immobility is the last defense reaction to entrapment by a predator. In humans, peritraumatic tonic immobility was correlated with PTSD severity and poor response to treatment. This study compared the role of peritraumatic dissociation, panic physical symptoms and tonic immobility as predictors of response to standard pharmacotherapy for PTSD.(More)
OBJECTIVE To describe the prevalence of comorbid lifetime anxiety disorders in outpatients with schizophrenia and to compare the subjective quality of life of patients with and without comorbid anxiety disorders. METHODS Fifty-three outpatients were recruited. They were interviewed with the Anxiety Disorders section of the SCID for DSM-IV. Quality of life(More)
Data regarding the co-occurrence of anxiety symptoms or syndromes in schizophrenia is scant. Hierarchical assumptions embedded in diagnostic systems and methodologic difficulties hamper the development of studies on accessory symptomatology outside of the core positive-negative-disorganized symptoms. Recent studies have repeatedly challenged these(More)
A cross-sectional survey for posttraumatic stress disorder (PTSD) was conducted with 234 Brazilian ambulance workers (180 men and 54 women) using a sociodemographic questionnaire, the Posttraumatic Stress Disorder Checklist-Civilian Version, and the Short Form Health Survey-36. Current prevalence rates for full and partial PTSD were 5.6% (men = 6.7%, women(More)
Although video-EEG monitoring has revolutionized the diagnosis of psychogenic nonepileptic seizure (PNES), the etiology of this condition remains poorly understood. This article is a critical review of studies on the prevalence of traumatic events, abuse, and/or posttraumatic stress disorder (PTSD) in patients with PNES. Searches carried out on MEDLINE(More)
BACKGROUND Previous studies suggested the importance of peritraumatic reactions as predictors of PSTD symptoms severity. Despite mounting evidence that tonic immobility occurs under intense life threats its role as predictor of PTSD severity remains by and large understudied. The objective of this study was to investigate the role of peritraumatic reactions(More)
INTRODUCTION Tonic immobility is the last defense against predation in animals and is characterized by paralysis and analgesia. In humans, it has only been reported in women victims of sexual abuse. OBJECTIVE This study evaluated the prevalence of peritraumatic tonic immobility (PTI) in patients with PTSD and investigated its association with response to(More)
