Four Questions Nurses Can Ask to Predict PTSD 1 Year After a Motor Vehicle Crash.

BACKGROUND: The role of nurses in screening for posttraumatic stress disorder is crucial in trauma units. OBJECTIVES: To create and evaluate an easy and brief tool for nurses to predict chronic posttraumatic stress disorder 1 year after a motor vehicle crash. METHODS: We performed a 1-year follow-up multicenter study from 2007 to 2015, including 274 patients injured in a motor vehicle crash who were hospitalized in an orthopedic trauma unit. Nurses administered the DEPITAC questionnaire. Posttraumatic stress disorder was measured by the Post-Traumatic Stress Disorder Checklist of symptoms during the first year following the crash. A multivariable logistic regression model was implemented to select items significantly associated with posttraumatic stress disorder to improve the DEPITAC questionnaire. Predictive performance to predict posttraumatic stress disorder 1 year after the motor vehicle crash was examined for these different models. RESULTS: Of 274 patients studied, a total of 75.9% completed the questionnaire at 1 year of follow-up. We found that only two questions and two simple elements of the patient's medical record (other injury or a person dying during the crash, perception of vital threat, number of children, and length of stay in trauma) predicted posttraumatic stress disorder 1 year after a motor vehicle crash. CONCLUSIONS: The brevity of this evaluation, simple scoring rules, and screening test performance suggest that this new screening tool can be easily administered in the acute care setting by nurses.

Antiepileptic drugs and risk of suicide attempts: a case-control study exploring the impact of underlying medical conditions.

PURPOSE: Randomized-controlled trials and claims databases suggest that antiepileptic drug (AED) use may increase the risk of suicide attempts (SA). The present case-control study explores the impact of underlying indications on this potential association. METHODS: Physicians collected the medical history; prior 12-month drug use was obtained from standardized telephone interviews with patients. The association between AED use and SA was explored using multivariate conditional logistic regression. The analyses were replicated after stratification on depression and neurological disorders (epilepsy, migraine, and chronic neuropathic pain). RESULTS: Between 2008 and 2012, 506 adults with an incident SA were recruited in suicide treatment centers from across France and socio-demographically matched to 2829 controls from primary care settings. The association between AED use and odds of SA was not significant overall (odds ratio [OR], 1.5; 95% confidence interval [CI], 0.9-2.4). No association was observed for patients with neurological disorders (OR, 1.1; 95%CI, 0.5-2.4) as opposed to patients with depression (OR, 1.6; 95%CI, 1.0-2.5), but unmeasured confounding was suspected. CONCLUSIONS: Our results suggest that the association observed between AED use and increased odds of non-fatal SA in patients with either a lifetime history of depression or no neurological disorder may be explained by the presence of an underlying psychiatric disorder. Accounting for underlying indications is crucial in drug safety studies, as these can cause a reported association (or lack thereof) to be misleading. This may require the prospective collection of medical data at a patient level. Copyright © 2017 John Wiley & Sons, Ltd.

Intrusive experiences in posttraumatic stress disorder: Treatment response induces changes in the directed functional connectivity of the anterior insula.

BACKGROUND: One of the core features of posttraumatic stress disorder (PTSD) is re-experiencing trauma. The anterior insula (AI) has been proposed to play a crucial role in these intrusive experiences. However, the dynamic function of the AI in re-experiencing trauma and its putative modulation by effective therapy need to be specified. METHODS: Thirty PTSD patients were enrolled and exposed to traumatic memory reactivation therapy. Resting-state functional magnetic resonance imaging (fMRI) scans were acquired before and after treatment. To explore AI-directed influences over the rest of the brain, we referred to a mixed model using pre-/posttreatment Granger causality analysis seeded on the AI as a within-subject factor and treatment response as a between-subject factor. To further identify correlates of re-experiencing trauma, we investigated how intrusive severity affected (i) causality maps and (ii) the spatial stability of other intrinsic brain networks. RESULTS: We observed changes in AI-directed functional connectivity patterns in PTSD patients. Many within- and between-network causal paths were found to be less influenced by the AI after effective therapy. Insular influences were found to be positively correlated with re-experiencing symptoms, while they were linked with a stronger default mode network (DMN) and more unstable central executive network (CEN) connectivity. CONCLUSION: We showed that directed changes in AI signaling to the DMN and CEN at rest may underlie the degree of re-experiencing symptoms in PTSD. A positive response to treatment further induced changes in network-to-network anticorrelated patterns. Such findings may guide targeted neuromodulation strategies in PTSD patients not suitably improved by conventional treatment.

Catatonia and consultation-liaison psychiatry study of 12 cases.

Nowadays, catatonia is no more considered as a subtype of schizophrenia. Catatonia seems more frequently associated to mood disorders as well as general medical conditions. It is sometimes difficult to associate formally a medical etiology to this syndrome. But we found, in the literature, three groups of associated general medical conditions: neurological disorders, drug induced and toxic induced conditions, metabolic conditions. We present a prospective study of 12 clinical cases of catatonia due to general medical conditions we realized in the Consultation-Liaison Psychiatry Department of the University Hospital of LILLE (France) during a period of 5 months. We find coherent data with the literature. However, our results suggest that if medical conditions precipitate the catatonia syndrome, they are rarely its only etiology. We think that if somatic factors are co-morbid with psychiatric conditions they do not necessarily predominate as the target of treatment. The treatment of the catatonia must be a priority and remain symptomatic, to allow in parallel the specific treatment for the somatic disorder or the psychiatric disorder.

[Hypersexuality in Parkinson's disease. Advantage of the presence of the entourage for medical assessment]. / Prise en charge de l'hypersexualité dans la maladie de Parkinson. Intérêt de la présence de l'entourage lors de l'évaluation médicale.

OBJECTIVE: To improve the management of hypersexuality caused by antiparkinsonian treatment and its psychopathological implications in patients with Parkinson's disease (PD). If hypersexuality is a classic form of impulse control disorder (ICD) observed in PD, its rate is certainly underestimated. METHODS: We have proposed to meet patients with Parkinson's disease, referred by the neurology department of Lille University Hospital, for detection or suspicion of hypersexuality, in the presence of their spouse. The session consisted of an interview conducted by our psychiatry team. This evaluation was conducted between January 1 and August 31, 2011. Nine patients were referred to our service, 7 agreed to meet us, 6 of them with their spouse. RESULTS: An interview in the presence of the spouse has improved hypersexuality screening and information given to the patient and his close contacts regarding the side effects of treatment, and particularly the occurrence of hypersexuality. It also highlighted the various expressions of these behavioral changes, often minimized by patients, as spouses had great difficulty dealing with this. It helped them to improve verbal communication and, therefore, to be more informative concerning sexual behavior changes in connection with the treatment and its management. Finally, it has enabled improved support for secondary consequences of this impulse control disorder, such as guilt, jealousy or shame. Our interest has also focused on the impact of this hypersexuality on patients' families. Among the six sets partners, four had symptoms requiring specific psychiatric care: depression, suicidal intention or post-traumatic stress disorder. PERSPECTIVE: Hypersexuality seems underestimated in patients receiving antiparkinsonian treatment. This underestimation is probably linked to some defense mechanisms such as denial or minimization, but also to the feelings generated by these behavioral problems, such as shame or guilt. On the other hand, some patients do not experience stress related behavioral changes (even though the family may complain). Systematic partner interview could be a solution to improving this screening.
