Abstract Acute seizures frequently occur following severe traumatic brain injury (TBI) and have been associated with poor patient prognosis. Silent or nonconvulsive seizures (NCS) manifest in the absence of motor convulsion, can only be detected via continuous electroencephalographic (EEG) recordings, and are often unidentified and untreated. Identification of effective anti-epileptic drugs (AED) against post-traumatic NCS remains crucial to improve neurological outcome. Here, we assessed the anti-seizure profile of ethosuximide (ETX, 12.5–187.5 mg/kg) and phenytoin (PHT, 5–30 mg/kg) in a spontaneously occurring NCS model associated with penetrating ballistic-like brain injury (PBBI). Rats were divided between two drug cohorts, PHT or ETX, and randomly assigned to one of four doses or vehicle within each cohort. Following PBBI, NCS were detected by continuous EEG monitoring for 72 h post-injury. Drug efficacy was evaluated on NCS parameters of incidence, frequency, episode duration, total duration, and onset latency. Both PHT and ETX attenuated NCS in a dose-dependent manner. In vehicle-treated animals, 69–73% experienced NCS (averaging 9–10 episodes/rat) with average onset of NCS occurring at 30 h post-injury. Compared with control treatment, the two highest PHT and ETX doses significantly reduced NCS incidence to 13–40%, reduced NCS frequency (1.8–6.2 episodes/rat), and delayed seizure onset: <20% of treated animals exhibited NCS within the first 48 h. NCS durations were also dose-dependently mitigated. For the first time, we demonstrate that ETX and PHT are effective against spontaneously occurring NCS following PBBI, and suggest that these AEDs may be effective at treating post-traumatic NCS.

Object Current standard of care for patients with severe traumatic brain injury (TBI) is prophylactic treatment with phenytoin for 7 days to decrease the risk of early posttraumatic seizures. Phenytoin alters drug metabolism, induces fever, and requires therapeutic-level monitoring. Alternatively, levetiracetam (Keppra) does not require serum monitoring or have significant pharmacokinetic interactions. In the current study, the authors compare the EEG findings in patients receiving phenytoin with those receiving levetiracetam monotherapy for seizure prophylaxis following severe TBI. Methods Data were prospectively collected in 32 cases in which patients received levetiracetam for the first 7 days after severe TBI and compared with data from a historical cohort of 41 cases in which patients received phenytoin monotherapy. Patients underwent 1-hour electroencephalographic (EEG) monitoring if they displayed persistent coma, decreased mental status, or clinical signs of seizures. The EEG results were grouped into normal and abnormal findings, with abnormal EEG findings further categorized as seizure activity or seizure tendency. Results Fifteen of 32 patients in the levetiracetam group warranted EEG monitoring. In 7 of these 15 cases the results were normal and in 8 abnormal; 1 patient had seizure activity, whereas 7 had seizure tendency. Twelve of 41 patients in the phenytoin group received EEG monitoring, with all results being normal. Patients treated with levetiracetam and phenytoin had equivalent incidence of seizure activity (p = 0.556). Patients receiving levetiracetam had a higher incidence of abnormal EEG findings (p = 0.003). Conclusions Levetiracetam is as effective as phenytoin in preventing early posttraumatic seizures but is associated with an increased seizure tendency on EEG analysis. PMID:18828701

Post-traumatic stress was assessed in early and late pregnancy, and 1, 4, 7, and 11 months postpartum by means of questionnaires among 1224 women. Thirty-seven women (3%) had post-traumatic stress (meeting criteria B, C, and D for PTSD) at least once within 1-11 months postpartum. In pregnancy, depression, severe fear of childbirth, 'pre'-traumatic stress, previous counseling related to pregnancy/childbirth, and self-reported previous psychological problems were associated with an increased risk of having post-traumatic stress within 1-11 months postpartum. Sum-scores of post-traumatic stress did not decrease over time among women who at least once had post-traumatic stress (criteria B, C, and D) within 1-11 months postpartum. Women with post-traumatic stress also showed a decrease in perceived social support over time postpartum.

Pediatric post-traumatic epilepsy incidence varies depending on reporting mechanism and injury severity; anti-epileptic drug (AEDs) use also varies with lack of quality evidence-based data. Adverse AED effects are not negligible; some may negatively affect functional outcome. This review focuses on clarifying available data. This review discusses seizures associated with traumatic brain injury in children, including seizure incidence, relationship to severity of injury, potential detrimental effects of seizures, potential benefits of AED, adverse effects of AED, new developments in preventing epileptogenesis, and suggested recommendations for patient management. English language papers were identified from PubMed using search terms including but not excluding the following: adverse drug effects, anti-epileptic drugs, children, electroencephalogram, epilepsy, epileptogenesis, head injury, levetiracetam, pediatrics, phenytoin, post-traumatic epilepsy, prevention, prophylaxis, seizures, and traumatic brain injury. Expert commentary: Identification of high-risk patients for post-traumatic seizures is a key goal. Levetiracetam may prevent epileptogenesis, as may other developments.

Post-traumatic epilepsy (PTE) occurs in 20% of individuals with acquired epilepsy, and can impact significantly the quality of life due to the seizures and other functional or cognitive and behavioral outcomes of the traumatic brain injury (TBI) and PTE. There is no available antiepileptogenic or disease modifying treatment for PTE. Animal models of TBI and PTE have been developed, offering useful insights on the value of inflammatory, neurodegenerative pathways, hemorrhages and iron accumulation, calcium channels and other target pathways that could be used for treatment development. Most of the existing preclinical studies test efficacy towards pathologies of functional recovery after TBI, while a few studies are emerging testing the effects towards induced or spontaneous seizures. Here we review the existing preclinical trials testing new candidate treatments for TBI sequelae and PTE, and discuss future directions for efforts aiming at developing antiepileptogenic and disease-modifying treatments.

Post-traumatic epilepsy (PTE) is defined as the development of unprovoked seizures in a delayed fashion after traumatic brain injury (TBI). PTE lies at the intersection of two distinct fields of study, epilepsy and neurotrauma. TBI is associated with a myriad of both focal and diffuse anatomic injuries, and an ideal animal model of epilepsy after TBI must mimic the characteristics of human PTE. The three most commonly used models of TBI are lateral fluid percussion, controlled cortical injury, and weight drop. Much of what is known about PTE has resulted from use of these models. In this review, we describe the most commonly used animal models of TBI with special attention to their advantages and disadvantages with respect to their use as a model of PTE.

Traumatic brain injury increases the risk of both early and late seizures. Antiepileptic prophylaxis reduces early seizures, but their use beyond 1 week does not prevent the development of post-traumatic epilepsy. Furthermore, prolonged prophylaxis exposes patients to side effects of the drugs and has occupational implications. The American Academy of Neurology recommends that antiepileptic prophylaxis should be started for patients with severe traumatic brain injury and discontinued after 1 week. An audit is presented here that investigates the use of prophylaxis in a cohort of military patients admitted to the UK Defence Medical Rehabilitation Centre (DMRC). Data were collected and analysed retrospectively from electronic and paper records between February 2009 and August 2012. The timing and duration of antiepileptic drug use and the incidence of seizures were recorded. During the study period, 52 patients with severe traumatic brain injury were admitted to the rehabilitation centre: 25 patients (48%) were commenced on prophylaxis during the first week following injury while 27 (52%) did not receive prophylaxis. Only one patient (2%) received prophylaxis for the recommended period of 1 week, 22 patients (42%) received prophylaxis for longer than 1 week with a mean duration of 6.2 months. Two patients (4%) had post-traumatic epilepsy and started on treatment at DMRC. The use of antiepileptic prophylaxis varies widely and is generally inconsistent with evidence-based guidance. This exposes some patients to a higher risk of early seizures and others to unnecessary use of antiepileptics. Better implementation of prophylaxis is required.

The objective of this study was to find risk factors in pregnancy for post-traumatic stress and depression 1 month after childbirth. Furthermore, the relation between post-traumatic stress and depression was explored. A prospective longitudinal study. Pregnant women in Linköping and Kalmar, Sweden. A total of 1224 women were assessed in pregnancy, week 12-20 and 32, as well as 1 month postpartum. Post-traumatic stress and depression after delivery were assessed 1 month postpartum. Potential risk factors were assessed in early and late pregnancy. Variables measured during pregnancy were trait anxiety, depression, fear of childbirth, childbirth-related traumatic stress, stress coping capacity, social support, parity, educational level, age, gestation week, parity, educational level, civil status, previous psychological/psychiatric counselling, and previous experience of any traumatic events. Delivery mode was assessed from the medical records. Prevalence of post-traumatic stress (criteria A, B, C, D, E, and F according to DSM-IV) and depression (Beck's depression inventory). One month postpartum, 12 (1.3%) women had post-traumatic stress (met symptom criteria B, C, and D for post-traumatic stress disorder according to Diagnostic and statistical manual of mental disorders, 4th edition [DSM-IV]). The most important risk factors in pregnancy were depression in early pregnancy (OR=16.3), severe fear of childbirth (OR=6.2), and 'pre'-traumatic stress (in view of the forthcoming delivery) in late pregnancy (OR=12.5). The prevalence of depression was 5.6%. Post-traumatic stress and depression were positively related 1 month postpartum and were predicted by mainly the same factors. Risk factors for post-traumatic stress and depression after childbirth can be assessed in early pregnancy. Post-traumatic stress and depression also seem to share the same underlying vulnerability factors.

Post-Traumatic Cognition Mediates the Relationship between a History of Sexual Abuse and the Post-Traumatic Stress Symptoms in Sexual Assault Victims

More than half of all sexual assault victims report experiencing sexual victimization more than once. The aim of this paper was to determine the role post-traumatic cognition plays in the relationship between a history of sexual abuse and post-traumatic stress symptoms in sexual assault victims. The relationship between a history of sexual assault and the severity of post-traumatic stress symptoms was investigated retrospectively using data from a sexual assault crisis center in Korea. Data on psychological symptoms were collected in person at the initial assessment and by telephone 1 month later using the Post-traumatic Cognitions Inventory and the Post-traumatic Stress Disorder Symptoms Scale: Self-report Version. Of 105 women included in the analysis, 10 (9.5%) reported prior sexual abuse and were classified as sexually revictimized. Revictimized women had more post-traumatic negative cognition at initial assessment (t = −2.98; P = 0.004) and more post-traumatic symptoms at 1 month follow-up (t = −2.39; P = 0.019) than singly victimized women. At 1 month follow-up, the severity of post-traumatic stress symptoms had increased in revictimized women but had decreased slightly in singly victimized women. Negative post-traumatic cognition fully mediated the association between a history of sexual abuse and the severity of post-traumatic stress symptoms. Early detection of sexually revictimized women and tailored service and treatment intervention is needed to better serve this group of victims. Interventions targeted at preventing revictimization or post crime victimization may also help victims recover from the trauma and prevent future abuse. PMID:28875614

Early Seizures Prematurely Unsilence Auditory Synapses to Disrupt Thalamocortical Critical Period Plasticity.

Heightened neural excitability in infancy and childhood results in increased susceptibility to seizures. Such early-life seizures are associated with language deficits and autism that can result from aberrant development of the auditory cortex. Here, we show that early-life seizures disrupt a critical period (CP) for tonotopic map plasticity in primary auditory cortex (A1). We show that this CP is characterized by a prevalence of "silent," NMDA-receptor (NMDAR)-only, glutamate receptor synapses in auditory cortex that become "unsilenced" due to activity-dependent AMPA receptor (AMPAR) insertion. Induction of seizures prior to this CP occludes tonotopic map plasticity by prematurely unsilencing NMDAR-only synapses. Further, brief treatment with the AMPAR antagonist NBQX following seizures, prior to the CP, prevents synapse unsilencing and permits subsequent A1 plasticity. These findings reveal that early-life seizures modify CP regulators and suggest that therapeutic targets for early post-seizure treatment can rescue CP plasticity. Copyright © 2018 The Authors.

Post-traumatic stress disorder and cardiovascular disease.

2017-04-01

In this paper, a first in a Series of two, we look at the evidence for an association of post-traumatic stress disorder with incident cardiovascular disease risk and the mechanisms that might cause this association, as well as the prevalence of post-traumatic stress disorder due to cardiovascular disease events and its associated prognostic risk. We discuss research done after the publication of previous relevant systematic reviews, and survey currently funded research from the two most active funders in the field: the National Institutes of Health and the US Veterans Administration. We conclude that post-traumatic stress disorder is a risk factor for incident cardiovascular disease, and a common psychiatric consequence of cardiovascular disease events that might worsen the prognosis of the cardiovascular disease. There are many candidate mechanisms for the link between post-traumatic stress disorder and cardiovascular disease, and several ongoing studies could soon point to the most important behavioural and physiological mechanisms to target in early phase intervention development. Similarly, targets are emerging for individual and environmental interventions that might offset the risk of post-traumatic stress disorder after cardiovascular disease events.

To determine the impact of post-traumatic stress disorder (PTSD) on headache characteristics and headache prognosis in U.S. soldiers with post-traumatic headache. PTSD and post-concussive headache are common conditions among U.S. Army personnel returning from deployment. The impact of comorbid PTSD on the characteristics and outcomes of post-traumatic headache has not been determined in U.S. Army soldiers. A retrospective cohort study was conducted among 270 consecutive U.S. Army soldiers diagnosed with post-traumatic headache at a single Army neurology clinic. All subjects were screened for PTSD at baseline using the PTSD symptom checklist. Headache frequency and characteristics were determined for post-traumatic headache subjects with and without PTSD at baseline. Headache measures were reassessed 3 months after the baseline visit, and were compared between groups with and without PTSD. Of 270 soldiers with post-traumatic headache, 105 (39%) met screening criteria for PTSD. There was no significant difference between subjects with PTSD and those without PTSD with regard to headache frequency (17.2 vs 15.7 headache days per month; P = .15) or chronic daily headache (58.1% vs 52.1%; P = .34). Comorbid PTSD was associated with higher headache-related disability as measured by the Migraine Disability Assessment Score. Three months after the baseline neurology clinic visit, the number of subjects with at least 50% reduction in headache frequency was similar among post-traumatic headache cases with and without PTSD (25.9% vs 26.8%). PTSD is prevalent among U.S. Army soldiers with post-traumatic headache. Comorbid PTSD is not associated with more frequent headaches or chronic daily headache in soldiers evaluated at a military neurology clinic for chronic post-traumatic headache. Comorbid PTSD does not adversely affect short-term headache outcomes, although prospective controlled trials are needed to better assess this relationship. © 2013 American Headache

This was a prospective study, affecting mild TBI (mTBI) (Glasgow Coma Scale 14-15) cases attending to the Emergency Department between January 2009 and April 2012 (40 months duration). Patients were divided into two groups (Group A: without PTA, and Group B: with PTA, and they were assessed according to the risk factors. A total of 1762 patients (males: 1002, 56.8%) were meeting study inclusion criteria [Group A: n = 1678 (83.8%), Group B: n = 84 (4.2%)]. Age, CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs, and skull base fractures), anticoagulation therapy and seizures were independent factors of PTA. There was no statistically significant correlation between PTA and sex, convexity fractures, stroke event, mechanism of mTBI (fall +/or beating), hypertension, coronary heart disease, chronic smokers and diabetes (p > 0.005). CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs and skull base fractures), age, seizures and anticoagulation/antiplatelet therapy, were independent factors of PTA and could be used as predictive factors after mTBI.

Seizure following traumatic brain injury (TBI) constitutes a common complication that requires effective prevention to improve the outcome of TBI. Phenytoin has been the only recommended antiepileptic drug (AED) for seizure prophylaxis; however, several shortcomings have affected its use. Intravenous levetiracetam has been available since 2006 and has been increasingly accepted as a seizure prophylaxis for brain injury, mainly due to its favorable pharmacokinetic features and minimal adverse events profile. However, the efficacy and safety of levetiracetam versus phenytoin for seizure prophylaxis following TBI are not well clarified. The aim of this study was to assess the efficacy and safety of levetiracetam versus phenytoin for seizure prophylaxis following TBI. We conducted a search of the MEDLINE, EMBASE, and Cochrane library databases to March 2016, and screened original research that included patients with TBI who received levetiracetam. We included randomized controlled trials (RCTs) or controlled observational cohort studies that compared levetiracetam and phenytoin, as well as uncontrolled case series regarding prophylactic levetiracetam following TBI. The outcomes included early or late seizure prophylaxis and safety. The estimates of seizure prophylaxis were pooled using a meta-analysis, and the estimates for the case series were pooled using descriptive statistics. A total of 1614 patients from 11 studies were included in this review, of whom 1285 patients from eight controlled studies (one RCT and seven cohort studies) were included in the meta-analysis. Levetiracetam was not superior to phenytoin with regard to early seizure prophylaxis (risk ratio [RR] 1.10, 95 % confidence interval [CI] 0.64-1.88); the estimate of early seizure incidence was 0.05 (95 % CI 0.02-0.08). Three studies that assessed late seizure did not indicate the superiority of levetiracetam to phenytoin. There were no differences in mortality during hospitalization or after 6�

The potentially debilitating effect of posttraumatic stress disorder (PTSD) has created much interest in early intervention strategies that can reduce PTSD. This review critiques the evidence for psychological debriefing approaches and alternate early intervention strategies. The review critiques the randomized controlled trials of psychological debriefing, and early provision of cognitive behavior therapy. The latter approach involves therapy attention on acutely traumatized individuals who are high risk for PTSD development, and particularly in people with acute stress disorder (ASD). Psychological debriefing does not prevent PTSD. Cognitive behaviour therapy strategies have proven efficacy in reducing subsequent PTSD in ASD populations. Despite the promising evidence for early provision of CBT, many people do not benefit from CBT. This review concludes with consideration of major challenges facing early intervention approaches in the context of terrorist attacks and mass disasters.

Deep Recurrent Neural Networks for seizure detection and early seizure detection systems

DOE Office of Scientific and Technical Information (OSTI.GOV)

Talathi, S. S.

Epilepsy is common neurological diseases, affecting about 0.6-0.8 % of world population. Epileptic patients suffer from chronic unprovoked seizures, which can result in broad spectrum of debilitating medical and social consequences. Since seizures, in general, occur infrequently and are unpredictable, automated seizure detection systems are recommended to screen for seizures during long-term electroencephalogram (EEG) recordings. In addition, systems for early seizure detection can lead to the development of new types of intervention systems that are designed to control or shorten the duration of seizure events. In this article, we investigate the utility of recurrent neural networks (RNNs) in designing seizuremore » detection and early seizure detection systems. We propose a deep learning framework via the use of Gated Recurrent Unit (GRU) RNNs for seizure detection. We use publicly available data in order to evaluate our method and demonstrate very promising evaluation results with overall accuracy close to 100 %. We also systematically investigate the application of our method for early seizure warning systems. Our method can detect about 98% of seizure events within the first 5 seconds of the overall epileptic seizure duration.« less

Cortico-cortical evoked potentials offer the possibility of understanding connectivity within seizure networks to improve diagnosis and more accurately identify candidates for seizure surgery. We sought to determine if cortico-cortical evoked potentials and post-stimulation oscillatory changes differ for sites of EARLY versus LATE ictal spread. 37 patients undergoing stereoelectroencephalography were tested using a cortico-cortical evoked potential paradigm. All electrodes were classified according to the speed of ictal spread. EARLY spread sites were matched to a LATE spread site equidistant from the onset zone. Root-mean-square was used to quantify evoked responses and post-stimulation gamma band power and coherence were extracted and compared. Sites of EARLY spread exhibited significantly greater evoked responses after stimulation across all patients (t(36)=2.973, p=0.004). Stimulation elicited enhanced gamma band activity at EARLY spread sites (t(36)=2.61, p=0.03, FDR corrected); this gamma band oscillation was highly coherent with the onset zone. Cortico-cortical evoked potentials and post-stimulation changes in gamma band activity differ between sites of EARLY versus LATE ictal spread. The oscillatory changes can help visualize connectivity within the seizure network. Copyright © 2015 Elsevier B.V. All rights reserved.

Head injury is a common event and can cause a spectrum of motor and cognition disabilities. A frequent complication is seizures. Antiepileptic drugs (AED) such as phenytoin are often used in clinical practice with the hopes of preventing post-traumatic epilepsy. Whether immediate medical intervention following head trauma with either AEDs or neuroprotective drugs can alter the process of epileptogenesis and lead to a more favorable outcome is currently unknown. This review attempted to address the effectiveness of these treatment interventions. This review updates and expands on the earlier Cochrane review. To compare the efficacy of antiepileptic drugs and neuroprotective agents with placebo, usual care or other pharmacologic agents for the prevention of post-traumatic epilepsy in people diagnosed with any severity of traumatic brain injury. We searched The Cochrane Epilepsy Group's specialized register, CENTRAL, MEDLINE, ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform (ICTRP) in January 2015. We searched EMBASE, Biological Abstracts and National Research Register in September 2014 and SCOPUS in December 2013. The Cochrane Epilepsy Group performed handsearches of relevant journals. We included randomized controlled trials (RCTs) that include AEDs or neuroprotective agents compared with placebo, another pharmacologic agent or a usual care group. The outcomes measured included a seizure occurring within one week of trauma (early seizure), seizure occurring later than one week post-trauma (late seizure), mortality and any adverse events. Two review authors independently assessed study quality and extracted the data. We calculated risk ratios (RR) and 95% confidence intervals (CI) for each outcome. We used random-effects models in the meta-analyses and performed pre-defined subgroup and sensitivity analyses. This review included 10 RCTs (reported in 12 articles) consisting of 2326 participants The methodological quality

Influence of early stress on memory reconsolidation: Implications for post-traumatic stress disorder treatment

PubMed Central

Birmes, Philippe; Ferry, Barbara

2018-01-01

Post-traumatic stress disorder (PTSD) is a common consequence of exposure to a life-threatening event. Currently, pharmacological treatments are limited by high rates of relapse, and novel treatment approaches are needed. We have recently demonstrated that propranolol, a β-adrenergic antagonist, inhibited aversive memory reconsolidation in animals. Following this, in an open-label study 70% of patients with PTSD treated with propranolol during reactivation of traumatic memory exhibited full remission. However, the reason why 30% of these patients did not respond positively to propranolol treatment is still unclear. One of the major candidates as factor of treatment resistance is the patient's early-life traumatic history. To test the role of this factor, mice with pre- or postnatal stress are being tested in fear conditioning and in a new behavioral task, the "city-like", specifically designed as a mouse model of PTSD. After reactivation of the traumatic event, mice received propranolol injection to block the noradrenergic system during memory reconsolidation. Results show that, in the “city-like” test, control mice strongly avoided the shock compartment but also the compartments containing cues associated with the electric shocks. Injection of propranolol after reactivation greatly reduced the memory of the traumatic event, but this effect was not present when mice had received pre- or postnatal stress. Moreover, propranolol produced only a very weak effect in the fear conditioning test, and never changed the corticosterone level whatever the behavioral experiment. Taken together our results suggest that our new behavioural paradigm is well adapted to PTSD study in mice, and that early stress exposure may have an impact on propranolol PTSD treatment outcome. These data are critical to understanding the effect of propranolol treatment, in order to improve the therapeutic protocol currently used in humans. PMID:29352277

Post-traumatic stress disorder (PTSD) is a common consequence of exposure to a life-threatening event. Currently, pharmacological treatments are limited by high rates of relapse, and novel treatment approaches are needed. We have recently demonstrated that propranolol, a β-adrenergic antagonist, inhibited aversive memory reconsolidation in animals. Following this, in an open-label study 70% of patients with PTSD treated with propranolol during reactivation of traumatic memory exhibited full remission. However, the reason why 30% of these patients did not respond positively to propranolol treatment is still unclear. One of the major candidates as factor of treatment resistance is the patient's early-life traumatic history. To test the role of this factor, mice with pre- or postnatal stress are being tested in fear conditioning and in a new behavioral task, the "city-like", specifically designed as a mouse model of PTSD. After reactivation of the traumatic event, mice received propranolol injection to block the noradrenergic system during memory reconsolidation. Results show that, in the "city-like" test, control mice strongly avoided the shock compartment but also the compartments containing cues associated with the electric shocks. Injection of propranolol after reactivation greatly reduced the memory of the traumatic event, but this effect was not present when mice had received pre- or postnatal stress. Moreover, propranolol produced only a very weak effect in the fear conditioning test, and never changed the corticosterone level whatever the behavioral experiment. Taken together our results suggest that our new behavioural paradigm is well adapted to PTSD study in mice, and that early stress exposure may have an impact on propranolol PTSD treatment outcome.

Post-traumatic neurodegeneration and chronic traumatic encephalopathy.

Traumatic brain injury (TBI) is a leading cause of mortality and morbidity around the world. Concussive and subconcussive forms of closed-head injury due to impact or blast neurotrauma represent the most common types of TBI in civilian and military settings. It is becoming increasingly evident that TBI can lead to persistent, long-term debilitating effects, and in some cases, progressive neurodegeneration and chronic traumatic encephalopathy (CTE). The epidemiological literature suggests that a single moderate-to-severe TBI may be associated with accelerated neurodegeneration and increased risk of Alzheimer's disease, Parkinson's disease, or motor neuron disease. However, the pathologic phenotype of these post-traumatic neurodegenerations is largely unknown and there may be pathobiological differences between post-traumatic disease and the corresponding sporadic disorder. By contrast, the pathology of CTE is increasingly well known and is characterized by a distinctive pattern of progressive brain atrophy and accumulation of hyperphosphorylated tau neurofibrillary and glial tangles, dystrophic neurites, 43 kDa TAR DNA-binding protein (TDP-43) neuronal and glial aggregates, microvasculopathy, myelinated axonopathy, neuroinflammation, and white matter degeneration. Clinically, CTE is associated with behavioral changes, executive dysfunction, memory deficits, and cognitive impairments that begin insidiously and most often progress slowly over decades. Although research on the long-term effects of TBI is advancing quickly, the incidence and prevalence of post-traumatic neurodegeneration and CTE are unknown. Critical knowledge gaps include elucidation of pathogenic mechanisms, identification of genetic risk factors, and clarification of relevant variables-including age at exposure to trauma, history of prior and subsequent head trauma, substance use, gender, stress, and comorbidities-all of which may contribute to risk profiles and the development of post-traumatic

OBJECTIVE Posttraumatic seizure is a major complication following traumatic brain injury (TBI). The aim of this study was to determine the variation in seizure prophylaxis in select pediatric trauma centers. The authors hypothesized that there would be wide variation in seizure prophylaxis selection and use, within and between pediatric trauma centers. METHODS In this retrospective multicenter cohort study including 5 regional pediatric trauma centers affiliated with academic medical centers, the authors examined data from 236 children (age < 18 years) with severe TBI (admission Glasgow Coma Scale score ≤ 8, ICD-9 diagnosis codes of 800.0-801.9, 803.0-804.9, 850.0-854.1, 959.01, 950.1-950.3, 995.55, maximum head Abbreviated Injury Scale score ≥ 3) who received tracheal intubation for ≥ 48 hours in the ICU between 2007 and 2011. RESULTS Of 236 patients, 187 (79%) received seizure prophylaxis. In 2 of the 5 centers, 100% of the patients received seizure prophylaxis medication. Use of seizure prophylaxis was associated with younger patient age (p < 0.001), inflicted TBI (p < 0.001), subdural hematoma (p = 0.02), cerebral infarction (p < 0.001), and use of electroencephalography (p = 0.023), but not higher Injury Severity Score. In 63% cases in which seizure prophylaxis was used, the patients were given the first medication within 24 hours of injury, and 50% of the patients received the first dose in the prehospital or emergency department setting. Initial seizure prophylaxis was most commonly with fosphenytoin (47%), followed by phenytoin (40%). CONCLUSIONS While fosphenytoin was the most commonly used medication for seizure prophylaxis, there was large variation within and between trauma centers with respect to timing and choice of seizure prophylaxis in severe pediatric TBI. The heterogeneity in seizure prophylaxis use may explain the previously observed lack of relationship between seizure prophylaxis and outcomes.

To evaluate spectrum of causes & their characteristic findings in peripartum head ache and seizures on computed tomography & magnetic resonance imaging. Forty patients with complaints of peripartum headache and seizures underwent cross sectional imaging with computed tomography and magnetic resonance imaging during period of June 2011 to May 2012. Age group of subjects in this study was 18 to 38 y. Out of 40 patients 15 had history of eclampsia and remaining 25 patients were normotensive. Subjects with complaints of headache and seizures after six weeks of delivery were excluded from the study. Intravenous contrast was administered in cases with diagnostic dilemma. All results were reported and informed to the referring physicians on priority bases. Nine patients with peripartum headache and seizures revealed no brain parenchymal or cerebral vascular abnormalities on imaging. Eleven patients with a history of eclampsia showed features of eclamptic encephalopathy. Out 40 patients, 17 patients revealed cortical venous thrombosis with 14 patients showing parenchymal changes. One patient each showed features of meningoencephalitis, ischemic watershed territory infarct & region of gliosis. All results were analysed & tabulated. Eclamptic encephalopathy and cortical venous thrombosis are the major causes for post partum headache and seizures. Rational use of CT & MRI in the early course of the disease helps in characterizing the lesion and providing the appropriate treatment.

To report an analysis of the concept of perinatal post-traumatic stress disorder. Prevalence of perinatal post-traumatic stress disorder is rising in the USA, with 9% of the U.S. perinatal population diagnosed with the disorder and an additional 18% being at risk for the condition. Left untreated, adverse maternal-child outcomes result in increased morbidity, mortality and healthcare costs. Concept analysis via Walker and Avant's approach. The databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Academic Search Premier and PsychINFO were searched for articles, written in English, published between 2006-2015, containing the terms perinatal and post-traumatic stress disorder. Perinatal post-traumatic stress disorder owns unique attributes, antecedents and outcomes when compared to post-traumatic stress disorder in other contexts, and may be defined as a disorder arising after a traumatic experience, diagnosed any time from conception to 6 months postpartum, lasting longer than 1 month, leading to specific negative maternal symptoms and poor maternal-infant outcomes. Attributes include a diagnostic time frame (conception to 6 months postpartum), harmful prior or current trauma and specific diagnostic symptomatology defined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Antecedents were identified as trauma (perinatal complications and abuse), postpartum depression and previous psychiatric history. Consequences comprised adverse maternal-infant outcomes. Further research on perinatal post-traumatic stress disorder antecedents, attributes and outcomes in ethnically diverse populations may provide clinicians a more comprehensive framework for identifying and treating perinatal post-traumatic stress disorder. Nurses are encouraged to increase their awareness of perinatal post-traumatic stress disorder for early assessment and intervention, and prevention of adverse maternal-infant outcomes. © 2017 John Wiley

Seizures after primary intracerebral hemorrhage (PICH) are significant and treatable complications, but the factors predicting immediate, early and late seizures are poorly known. We investigated characteristics and outcome with special reference to occurrence and timing of a first seizure among consecutive subjects with PICH. A population-based study was conducted in Northern Ostrobothnia, Finland, in 1993-2008 that included all patients with a first-ever primary ICH without any prior diagnosis of epilepsy. Immediate (<24h after admission), early (1-14 days) and late (>2 weeks) seizures were considered separately. Out of a total of 935 ICH patients, 51 had immediate, 21 early and 58 late seizures. The patients with seizures were significantly younger than the others and more often had a subcortical hematoma location (p<0.05). Lifestyle factors did not differ between the groups. The risk factors for immediate seizures in multivariable analysis were a low Glasgow coma scale score (GCS) on admission, subcortical location and age inversely (p<0.01). The only independent risk factor for early seizures was subcortical location (p<0.001), whereas subcortical location (p<0.001), age inversely (p<0.01) and hematoma evacuation (p<0.05) independently predicted late seizures. Immediate and early seizures predicted infectious complications (p<0.05). Patients with subcortical hematoma and of younger age are at risk for immediate seizures after primary ICH irrespective of hematoma size. Patients with immediate and early seizures more often had infectious complications. Surgery increases the risk of a late seizure after ICH. Copyright © 2014 Elsevier B.V. All rights reserved.

The last decades have demonstrated the value of early interventions after a traumatic event. The purpose of these interventions is to prevent the development of psychological consequences such as post-traumatic stress disorder. Psychological debriefing is clearly the most popular intervention. However, in the literature, it is subject to a real controversy. The objective of the present paper is to define the interest of psychological debriefing, but also alternative therapeutical strategies for people exposed to traumatic events.

Traumatic birth experiences may lead to serious psychological impairment. Recent studies show that a considerable number of women can develop post-traumatic stress disorder (PTSD), in some cases in a subsyndromal form. Until now, the possibility that postpartum psychological symptoms might be a continuum of a pre-existing disorder in pregnancy has rarely been considered. This study therefore aimed to evaluate the proportion of women who develop post-traumatic stress disorder as a result of childbirth. Materials and Methods: 56 multiparous women were recruited for the study. The diagnosis of PTSD was made according to the criteria for psychological disorders in the DSM-IV (Diagnostics and Statistical Manual of Mental Disorders). The data were collected in structured interviews in the 30th to 38th week of gestation and in the 6th week post partum. Results: Of the 56 women participating, 52 (93 %) completed the survey. Uncontrolled results showed that 21.15 % of the multiparous women met the full diagnostic PTSD criteria in the 6th week post partum. After the exclusion of all cases already characterised by all criteria or a subsyndromal form of PTSD caused by previous traumatisation, the PTSD rate was below 8 % at 6 weeks postpartum (= incidence rate of PTSD post partum). Conclusions: The present study is the first prospective longitudinal study to demonstrate the occurrence of full criteria PTSD in multiparous women as a result of childbirth after having excluded pre-existing PTSD. The results of our study show a high prevalence rate of PTSD during pregnancy. A number of women report all aspects of post-traumatic stress disorder as a result of childbirth. PMID:25253905

Endorphin mediation of post-ictal effects of kindled seizures in rats.

PubMed

Kelsey, J E; Belluzzi, J D

1982-12-16

Brief electrical stimulation of the enkephalin-rich globus pallidus at 1-h intervals produced kindled, clonic seizures in rats as rapidly as similar stimulation of the amygdala. Massing the kindling trials at 10-min intervals inhibited the occurrence of subsequent seizures, especially following globus pallidus stimulation. Naloxone (20 mg/kg), an opiate receptor antagonist, reversed this post-ictal inhibition of seizures following massed trials, but had no effect on seizures kindled at 1-h intervals. Thus, endorphin-released during seizures do not appear to mediate the production of kindled seizures, but do appear to mediate the transient posts ictal inhibition of seizures.

Traumatic brain injury (TBI) is a well-known risk factor for seizures. We aimed to identify the frequency and risk factors for seizure occurrence during hospitalization for TBI. We used ICD-9-CM codes to identify patients 18 years of age or older from the National Trauma Data Bank who were admitted with TBI. We also used ICD-9-CM codes to identify the subset who had seizures during hospitalization. Patient demographics, comorbidities, Glasgow Coma Scale (GCS) score, Injury Severity Score Abbreviated Injury Scale (ISSAIS), in-hospital complications, and discharge disposition were compared in the seizure group (SG) and no-seizure group (NSG). A total of 1559 patients had in-hospital seizures, comprising 0.4% of all patients admitted with TBI. The mean age of SG was 3 years older than NSG [51 vs. 48; p < 0.0001]. African-American ethnicity (20 vs. 12%, p < 0.0001) and moderate TBI (8 vs. 4%, p < 0.0001) were more common in SG. History of alcohol dependence was more common in the SG (25 vs. 11%, p < 0.0001). Fall was the most common mechanism of injury in SG (56 vs. 36% in NSG; p < 0.0001). Subdural hematoma was more common in SG (31 vs. 21%, p < 0.0001). SG had higher rates of pneumonia, ARDS, acute kidney injury, and increased ICP. The average length of hospital stay was significantly higher in SG (10 vs. 6 days, p < 0.0001), and these patients had higher rate of discharge to nursing facility (32 vs. 25%, p < 0.0001). In-hospital seizures occur in 0.4% of all TBI patients. Although infrequent, seizure occurrence is associated with higher rates of hospital complications such as pneumonia and ARDS and is an independent predictor of longer hospital stay and worse hospital outcome.

Background Epilepsy surgery is a potentially curative treatment option for pharmacoresistent patients. If non-invasive methods alone do not allow to delineate the epileptogenic brain areas the surgical candidates undergo long-term monitoring with intracranial EEG. Visual EEG analysis is then used to identify the seizure onset zone for targeted resection as a standard procedure. Methods Despite of its great potential to assess the epileptogenicty of brain tissue, quantitative EEG analysis has not yet found its way into routine clinical practice. To demonstrate that quantitative EEG may yield clinically highly relevant information we retrospectively investigated how post-operative seizure control is associated with four selected EEG measures evaluated in the resected brain tissue and the seizure onset zone. Importantly, the exact spatial location of the intracranial electrodes was determined by coregistration of pre-operative MRI and post-implantation CT and coregistration with post-resection MRI was used to delineate the extent of tissue resection. Using data-driven thresholding, quantitative EEG results were separated into normally contributing and salient channels. Results In patients with favorable post-surgical seizure control a significantly larger fraction of salient channels in three of the four quantitative EEG measures was resected than in patients with unfavorable outcome in terms of seizure control (median over the whole peri-ictal recordings). The same statistics revealed no association with post-operative seizure control when EEG channels contributing to the seizure onset zone were studied. Conclusions We conclude that quantitative EEG measures provide clinically relevant and objective markers of target tissue, which may be used to optimize epilepsy surgery. The finding that differentiation between favorable and unfavorable outcome was better for the fraction of salient values in the resected brain tissue than in the seizure onset zone is consistent

Post-stroke seizures are considered as a major cause of epilepsy in adults. The pathophysiologic mechanisms resulting in post-stroke seizures are not fully understood. The present study attempted to reveal a new mechanism underlying neuronal hyperexcitability responsible to the seizure development after ischemic stroke. Transient global ischemia was produced in adult Wistar rats using the 4-vessel occlusion (4-VO) method. The spontaneous behavioral seizures were defined by the Racine scale III-V. The neuronal death in the brain was determined by hematoxylin-eosin staining. The expression levels of A-type potassium channels were analyzed by immunohistochemical staining and western blotting. We found that the incidence of spontaneous behavioral seizures increased according to the severity of ischemia with 0% after 15-min ischemia and ∼50% after 25-min ischemia. All behavioral seizures occurred with 48h after ischemia. Morphological analysis indicated that brain damage was not correlated with behavioral seizures. Immunohistochemical staining showed that the expression levels of the A-type potassium channel subunit Kv4.2 was significantly reduced in ischemic brains with behavioral seizures, but not in ischemic brains without seizures. In addition, rats failing to develop spontaneous behavioral seizures within 2days after ischemia were more sensitive to bicuculline-induced seizures at 2 months after ischemia than control rats. Meanwhile, Kv4.2 expression was decreased in brain at 2 months after ischemia. Our results demonstrated the reduction of Kv4.2 expression might contribute to the development of post-ischemic seizures and long-term increased seizure susceptibility after ischemia. The mechanisms underlying post-stroke seizures and epilepsy is unknown so far. The down-regulation of IA channels may explained the abnormal neuronal hyperexcitability responsible for the seizure development after ischemic stroke. Copyright © 2016 Elsevier B.V.

Post-traumatic seizures can exacerbate injurious outcomes of severe brain trauma, yet effective treatments are limited owing to the complexity of the pathology underlying the concomitant occurrence of both events. In this study, we tested C-10068, a novel deuterium-containing analog of (+)-N-methyl-3-ethoxymorphinan, in a rat model of penetrating ballistic-like brain injury (PBBI) and evaluated the effects of C-10068 on PBBI-induced nonconvulsive seizures (NCS), acute neuroinflammation, and neurofunctional outcomes. NCS were detected by electroencephalographic monitoring. Neuroinflammation was evaluated by immunohistochemical markers, for example, glial fibrillary acidic protein and major histocompatibility complex class I, for activation of astrocytes and microglia, respectively. Neurofunction was tested using rotarod and Morris water maze tasks. Three infusion doses of C-10068 (1.0, 2.5, and 5.0 mg/kg/h × 72 h) were tested in the antiseizure study. Neuroinflammation and neurofunction were evaluated in animals treated with 5.0 mg/kg/h × 72 h C-10068. Compared to vehicle treatment, C-10068 dose dependently reduced PBBI-induced NCS incidence (40-50%), frequency (20-70%), and duration (30-82%). The most effective antiseizure dose of C-10068 (5.0 mg/kg/h × 72 h) also significantly attenuated hippocampal astrocyte activation and perilesional microglial reactivity post-PBBI. Within C-10068-treated animals, a positive correlation was observed in reduction in NCS frequency and reduction in hippocampal astrocyte activation. Further, C-10068 treatment significantly attenuated astrocyte activation in seizure-free animals. However, C-10068 failed to improve PBBI-induced motor and cognitive functions with the dosing regimen used in this study. Overall, the results indicating that C-10068 exerts both potent antiseizure and antiinflammatory effects are promising and warrant further investigation.

Behavioral problems and emotional difficulties at children of the veterans of war with post-traumatic stress disorder (PTSD) have not been researched entirely. In our country, which has a lot of persons suffering from some psychological traumas, this trauma seems to continue. The aim of this study was to determine the exposure, manifestations of behavioral problems and emotional difficulties at children and early adolescents, whose fathers were the veterans of war demonstrating post-traumatic stress disorder symptoms. The analyzed group comprised 120 school age children (10-15 years of age), whose parents/fathers were the veterans of war. The children were divided into two groups, and each group into the following two age sub-groups: 10-12 (children) and 13-15 (early adolescents) according to PTSD presence at their fathers - veterans of war. PTSD symptoms at fathers, veterans of war, were assessed using the Harvard Trauma Questionnaire-Bosnia and Herzegovina version and MKB-10 - audit of criteria. To assess the behavioral problems of children, the Child Behavior Checklist for parents was used, and to evaluate the neuroticism at children Hanes-Scale of neuroticism-extraversion was used while the depression level was evaluated using the Depression self-rating scale (DSRS). To analyze the obtained results, SPSS 17 program was used. The value p <0. 05 is considered significant. Children of fathers, the veterans of war, demonstrating the PTSD symptoms show more problems in activity, social and school conduct as well as in symptoms of behavioral problems compared to the children whose fathers do not demonstrate the PTSD symptoms (p<0. 001). Children of the war veterans demonstrating the symptoms of the post-traumatic stress disorder show significant difference at neuroticism sub-scales (p<0.001). Negative correlation between PTSD and activity, social and school conduct has been determined (p <0. 01), while positive correlation was determined between PTSD of war veterans

We identified factors associated with early and late postoperative seizure control in patients with supratentorial meningioma plus preoperative seizures. In this retrospective study, univariate analysis and multivariate logistic regression analysis compared 24 clinical variables according to the occurrence of early (≤1 week) or late (>1 week) postoperative seizures. Sixty-two of 97 patients (63.9 %) were seizure free for the entire postoperative follow-up period (29.5 ± 11.8 months), while 13 patients (13.4 %) still had frequent seizures at the end of follow-up. Fourteen of 97 patients (14.4 %) experienced early postoperative seizures, and emergence of new postoperative neurological deficits was the only significant risk factor (odds ratio = 7.377). Thirty-three patients (34.0 %) experienced late postoperative seizures at some time during follow-up, including 12 of 14 patients with early postoperative seizures. Associated risk factors for late postoperative seizures included tumor progression (odds ratio = 7.012) and new permanent postoperative neurological deficits (odds ratio = 4.327). Occurrence of postoperative seizures in patients with supratentorial meningioma and preoperative seizure was associated with new postoperative neurological deficits. Reduced cerebral or vascular injury during surgery may lead to fewer postoperative neurological deficits and better seizure outcome.

In epilepsy it has been challenging to detect early changes in brain activity that occurs prior to seizure onset and to map their origin and evolution for possible intervention. Besides, preclinical seizure experiments need to be conducted in awake animals with images reconstructed and displayed in real-time. We demonstrate using a rat model of generalized epilepsy that diffuse optical tomography (DOT) provides a unique functional neuroimaging modality for noninvasively and continuously tracking brain activities with high spatiotemporal resolution. We developed methods to conduct seizure experiments in fully awake rats using a subject-specific helmet and a restraining mechanism. For the first time, we detected early hemodynamic responses with heterogeneous patterns several minutes preceding the electroencephalographic seizure onset, supporting the presence of a "pre-seizure" state both in anesthetized and awake rats. Using a novel time-series analysis of scattering images, we show that the analysis of scattered diffuse light is a sensitive and reliable modality for detecting changes in neural activity associated with generalized seizure. We found widespread hemodynamic changes evolving from local regions of the bilateral cortex and thalamus to the entire brain, indicating that the onset of generalized seizures may originate locally rather than diffusely. Together, these findings suggest DOT represents a powerful tool for mapping early seizure onset and propagation pathways.

The aim of the present study was to identify the major factors correlated with early postoperative seizures in elderly patients who had undergone a meningioma resection, and subsequently, to develop a logistic regression equation for assessing the seizures risk. Fourteen factors possibly correlated with early postoperative seizures in a cohort of 209 elderly patients who had undergone meningioma resection, as analyzed by multifactorial stepwise logistic regression. Phenobarbital sodium (0.1 g, intramuscularly) was administered to all 209 patients 30 min prior to undergoing surgery. All the patients had no previous history of seizures. The correlation of the 14 clinical factors (gender, tumor site, dyskinesia, peritumoral brain edema (PTBE), tumor diameter, pre- and postoperative prophylaxes, surgery time, tumor adhesion, circumscription, blood supply, intraoperative transfusion, original site of the tumor and dysphasia) was assessed in association with the risk for post-operative seizures. Tumor diameter, postoperative prophylactic antiepileptic drug (PPAD) administration, PTBE and tumor site were entered as risk factors into a mathematical regression model. The odds ratio (OR) of the tumor diameter was >1, and PPAD administration showed an OR >1, relative to a non-prophylactic group. A logistic regression equation was obtained and the sensitivity, specificity and misdiagnosis rates were 91.4, 74.3 and 25.7%, respectively. Tumor diameter, PPAD administration, PTBE and tumor site were closely correlated with early postoperative seizures; PTBE and PPAD administration were risk and protective factors, respectively.

Client-centred therapy, post-traumatic stress disorder and post-traumatic growth: theoretical perspectives and practical implications.

PubMed

Joseph, Stephen

2004-03-01

In practice it is not unusual for client-centred therapists to work with people who have experienced traumatic events. However, client-centred therapy is not usually considered within texts on traumatic stress and questions have been raised over the appropriateness of client-centred therapy with trauma survivors. The present study shows how, although he was writing well before the introduction of the term 'post-traumatic stress disorder', Carl Rogers provided a theory of therapy and personality that contains an account of threat-related psychological processes largely consistent with contemporary trauma theory. Rogers' theory provides the conceptual underpinnings to the client-centred and experiential ways of working with traumatized people. Furthermore, Rogers' theory provides an understanding of post-traumatic growth processes, and encourages therapists to adopt a more positive psychological perspective to their understanding of how people adjust to traumatic events.

Objective Early post-traumatic seizures (PTS) may contribute to worsened outcomes after traumatic brain injury (TBI). Evidence to guide the evaluation and management of early PTS in children is limited. We undertook a survey of current practices of continuous electroencephalographic monitoring (cEEG), seizure prophylaxis and the management of early PTS to provide essential information for trial design and the development of PTS management pathways. Design Surveys were sent to site principal investigators at all 43 sites participating in the ADAPT (Approaches and Decisions in Acute Pediatric TBI) trial at the time of the survey. Surveys consisted of 12 questions addressing strategies to (i) implement cEEG monitoring, (ii) PTS prophylaxis, (iii) treat acute PTS, (iv) treat status epilepticus (SE) and refractory status epilepticus (RSE) and (v) monitor anti-seizure drug levels. Setting Institutions comprised a mixture of free-standing children’s hospitals and university medical centers across the United States and Europe. Measurements and Main Results cEEG monitoring was available in the pediatric intensive care unit in the overwhelming majority of clinical sites (98%); however, the plans to operationalize such monitoring for children varied considerably. A similar majority of sites report that administration of prophylactic anti-seizure medications is anticipated in children (93%), yet a minority reports that a specified protocol for treatment of PTS is in place (43%). Reported medication choices varied substantially between sites, but the majority of sites reported pentobarbital for RSE (81%). Presence of an treatment protocols for seizure prophylaxis, early PTS, post-traumatic SE and RSE was associated with decreased reported medications (all p < 0.05). Conclusions This study reports the current management practices for early PTS in select academic centers after pediatric severe TBI.

Post-traumatic psychiatric disorders: PTSD is not the only diagnosis.

PubMed

Auxéméry, Yann

2018-05-01

Traumatic events and their consequences are often hidden or minimised by patients for reasons linked to the post-traumatic stress disorder itself (inexpressibility, shame, depressive thoughts, fear of stigmatisation, etc.). Although post-traumatic stress disorder (PTSD) remains the most widely known disorder, chronic post-traumatic psychiatric disorders are many and varied. After a trauma, the practitioner has to check for the different clinical forms of post-traumatic psychological consequences: PTSD is not the only diagnosis. Based on our own clinical experience compared to the international literature, we think necessary to build a didactic classification describing chronic post-traumatic symptoms and syndromes. Post traumatic depressions and bereavement lead to high risk of suicidal crisis and self-harm behaviours. Re-experiencing are felt with anxiety, hyper arousal increases anxious reactivity, and avoidance strategies increase anticipatory anxiety, indicating post-traumatic anxiety disorders (agoraphobia, specific phobia, obsessive compulsive disorder, separation anxiety, social phobia). Characterising an often-severe clinical picture, the co-occurrence of post-traumatic and chronic psychotic symptoms is not unusual (post-traumatic schizophrenia, post-traumatic depression with mood-congruent psychotic features, non-schizophrenic post-traumatic psychotic disorder, and bipolar reaction to trauma). A physical injury occurring at the same time as a traumatic exposure increases the risk of developing post-traumatic stress disorder later which, in turn, afflicts the subjective perception of the physical health (development of somatoform and psychosomatic disorders, comorbidity with a post-concussion syndrome). The trauma may cause a rupture in the biography of a person, also in his/her internal physiological functioning as in his/her social activities (impacts of instinctive functions and behaviours, personality changes, and adjustment difficulties on professional

Post-traumatic growth among the UK veterans following treatment for post-traumatic stress disorder.

2017-04-01

The aim of this paper was to examine levels of post-traumatic growth (PTG) in a sample of the UK veterans who had received treatment for post-traumatic stress disorder (PTSD). The study followed-up 149 UK veterans after they had completed standardised treatment for PTSD provided by Combat Stress. Data had previously been collected on a range of mental health outcomes before treatment, and then repeated 6 months after the end of treatment. For the current study, participants completed the post-traumatic growth inventory (PTGI) measure. Analysis was conducted to explore levels of PTG and whether there were any relationships between pretreatment and post-treatment ratings of mental health and PTG. The mean score on the PTGI was 32.6. Evidence of a treatment effect on levels of PTG was observed. There appeared to be a relationship between improvements in symptoms of PTSD and depression and higher levels of PTG. This study observed the presence of PTG following exposure to traumatic events within a sample of the UK veterans following their treatment for PTSD. PTG scores were moderately low in comparison to similar studies in the USA. Published by the BMJ Publishing Group Limited.

Traumatic neglected dislocations of hip in children are rare entity. Neglected traumatic dislocations of hip in children along with heterotopic ossification are still rare. Post traumatic neglected hip dislocations are to be diagnosed as early as possible and have to be treated with precision and aggression as the outcome of treatment for the same is not predictable. 5 year female with post-traumatic neglected hip dislocation with heterotopic ossification forming a pseudoacetabulum postero-superiorly in which femur head was lodged. The girl was operated by open reduction using Moore's Posterior approach and showed good results. Here is a mention of a rare case with a good 18 months follow up with no complication. Post-traumatic neglected posterior hip dislocation mostly requires open reduction and relocation of femoral head in original acetabulum with concentric reduction. Heterotopic ossification is a rare but known complication of traumatic dislocation of hip in children. Good results can be achieved in such cases and regular follow-up of patient is required post-operatively.

We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS.

Post-traumatic Guillain-Barré syndrome (GBS) is a rarely described potentially life-threatening cause of weakness. We sought to elucidate the clinical features and electrophysiological patterns of post-traumatic GBS as an aid to diagnosis. We retrospectively studied six patients diagnosed with post-traumatic GBS between 2014 and 2016 at Tianjin Medical University General Hospital, China. Clinical features, serum analysis, lumbar puncture results, electrophysiological examinations, and prognosis were assessed. All six patients had different degrees of muscular atrophy at nadir and in two, respiratory muscles were involved. Five also had damaged cranial nerves and four of these had serum antibodies against gangliosides. The most common electrophysiological findings were relatively normal distal latency, prominent reduction of compound muscle action potential amplitude, and absence of F-waves, which are consistent with an axonal form of GBS. It is often overlooked that GBS can be triggered by non-infectious factors such as trauma and its short-term prognosis is poor. Therefore, it is important to analyze the clinical and electrophysiological features of GBS after trauma. Here we have shown that electrophysiological evaluations are helpful for diagnosing post-traumatic GBS. Early diagnosis may support appropriate treatment to help prevent morbidity and improve prognosis.

Identify seizure onset electrodes that need to be resected for seizure freedom in children undergoing intracranial electroencephalography recording for treatment of medically refractory epilepsy. All children undergoing intracranial electroencephalography subdural grid electrode placement at the Children’s Hospital of Philadelphia from 2002-2008 were asked to enroll. We utilized intraoperative pictures to determine the location of the electrodes and define the resection cavity. A total of 15 patients had surgical fields that allowed for complete identification of the electrodes over the area of resection. Eight of 15 patients were seizure free after a follow up of 1.7 to 8 yr. Only one seizure-free patient had complete resection of all seizure onset associated tissue. Seizure free patients had resection of 64.1% of the seizure onset electrode associated tissue, compared to 35.2% in the not seizure free patients (p=0.05). Resection of tissue associated with infrequent seizure onsets did not appear to be important for seizure freedom. Resecting ≥ 90% of the electrodes from the predominant seizure contacts predicted post-operative seizure freedom (p=0.007). The best predictor of seizure freedom was resecting ≥ 90% of tissue involved in majority of a patient’s seizures. Resection of tissue under infrequent seizure onset electrodes was not necessary for seizure freedom. PMID:24563805

Comorbid Post-Traumatic Stress Disorder and Opioid Dependence.

PubMed

Patel, Rikinkumar S; Elmaadawi, Ahmed; Nasr, Suhayl; Haskin, John

2017-09-03

Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions. Since opioid withdrawal symptoms mimic hyper vigilance, this results in an exaggeration of the response of patients with post-traumatic stress disorder. This comorbidity is associated with worse health outcomes, as its pathophysiology involves a common neurobiological circuit. Opioid substitution therapy and psychotherapeutic medications in combination with evidence-based cognitive behavioral therapy devised for individuals with comorbid post-traumatic stress disorder and opioid dependence may improve treatment outcomes in this population. Therefore, we conclude that the screening for post-traumatic stress disorder in the opioid-abusing population is crucial. To understand the underlying mechanisms for this comorbidity and to improve the treatment response, further research should be encouraged.

[Morel-Lavallée syndrome and post-traumatic nodular fat necrosis: Two post-traumatic complications mimicking cellulitis].

PubMed

Moulin, C; Barthélémy, I; Emering, C; D'Incan, M

Dermal and subcutaneous inflammation following direct trauma is initially evocative of soft-tissue infection. However, two differential diagnoses must be considered: Morel-Lavallée syndrome and post-traumatic nodular fat necrosis. Case 1: a 51-year-old woman fell off her motorbike and had dermabrasions on her right and left tibial ridges that rapidly developed into dermo-hypodermitis of the entire limb. There was no improvement after 3 weeks of antibiotics. The patient was apyretic. She had a soft, non-inflammatory tumefaction on the inner aspect of her left knee. Ultrasound revealed subcutaneous collection in both legs. The surgeons confirmed a diagnosis of Morel-Lavallée syndrome and drained the two collections. Progress was good and the patient healed without major consequences. Case 2: following a fall on her stairs, a 40-year-old woman presented dermabrasions and haematomas on her left leg. Antibiotic therapy failed to prevent the progression of dermo-hypodermitis. The patient remained apyretic and there was no inflammatory syndrome. A CT scan showed thickening of a subcutaneous fat and fluid collection, resulting in diagnosis of post-traumatic nodular fat necrosis. Management was surgical and the outcome was good. These two cases show two post-traumatic cutaneous complications: Morel-Lavallée syndrome and post-traumatic nodular fat necrosis. Morel-Lavallée syndrome occurs after tangential trauma next to richly vascularized tissue. Post-traumatic nodular fat necrosis is defined as necrosis of adipocytes. In both cases, diagnosis is confirmed by imagery (Ultrasonography, tomography). Our two case reports show that inflammatory presentation of both Morel-Lavallée syndrome and post-traumatic nodular fat necrosis can lead to diagnostic and therapeutic errors while a surgical procedure is necessary since tissue necrosis can occur.

Characterization of Early Partial Seizure Onset: Frequency, Complexity and Entropy

Jouny, Christophe C.; Bergey, Gregory K.

2011-01-01

Objective A clear classification of partial seizures onset features is not yet established. Complexity and entropy have been very widely used to describe dynamical systems, but a systematic evaluation of these measures to characterize partial seizures has never been performed. Methods Eighteen different measures including power in frequency bands up to 300Hz, Gabor atom density (GAD), Higuchi fractal dimension (HFD), Lempel-Ziv complexity, Shannon entropy, sample entropy, and permutation entropy, were selected to test sensitivity to partial seizure onset. Intracranial recordings from forty-five patients with mesial temporal, neocortical temporal and neocortical extratemporal seizure foci were included (331 partial seizures). Results GAD, Lempel-Ziv complexity, HFD, high frequency activity, and sample entropy were the most reliable measures to assess early seizure onset. Conclusions Increases in complexity and occurrence of high-frequency components appear to be commonly associated with early stages of partial seizure evolution from all regions. The type of measure (frequency-based, complexity or entropy) does not predict the efficiency of the method to detect seizure onset. Significance Differences between measures such as GAD and HFD highlight the multimodal nature of partial seizure onsets. Improved methods for early seizure detection may be achieved from a better understanding of these underlying dynamics. PMID:21872526

Post-traumatic stress symptoms 5 years after military deployment to Afghanistan: an observational cohort study.

PubMed

2016-01-01

Deployment can put soldiers at risk of developing post-traumatic stress symptoms. Despite several longitudinal studies, little is known about the timing of an increase in post-traumatic stress symptoms relative to pre-deployment. Longitudinal studies starting pre-deployment, in which participants are repeatedly measured over time, are warranted to assess the timing of an increase in symptoms to ultimately assess the timing of an increase in treatment demand after deployment. In this large observational cohort study, Dutch military personnel who were deployed to Afghanistan as part of the International Security Assistance Forces between March, 2005, and September, 2008, were assessed for post-traumatic stress symptoms with the Self-Rating Inventory for Post-traumatic Stress Disorder (SRIP) questionnaire. Participants were assessed 1 month before deployment and followed up at 1 month, 6 months, 12 months, 2 years, and 5 years after deployment, with changes in SRIP scores compared with pre-deployment using a mixed model analysis. The primary outcome was the total score of post-traumatic stress symptoms measured with SRIP at pre-deployment and the five follow-up assessments, with a score of 38 used as the cutoff to indicate substantial post-traumatic stress symptoms. Between March, 2005, and September, 2008, 1007 participants were recruited to this study. The results show two important effects of deployment on post-traumatic stress symptoms. A short-term symptom increase within the first 6 months after deployment (symptom increase coefficient for SRIP score vs pre-deployment [β] 0·99, 95% CI 0·50-1·48); and a long-term symptom increase at 5 years after deployment (β 1·67, 1·14-2·20). This study underlines the importance of long-term monitoring of the psychological health of soldiers after deployment because early detection of symptoms is essential to early treatment, which is related to improved psychological health.

High rates of adverse outcomes have been reported following blast-related concussive traumatic brain injury in US military personnel, but the extent to which such adverse outcomes can be predicted acutely after injury is unknown. We performed a prospective, observational study of US military personnel with blast-related concussive traumatic brain injury (n = 38) and controls (n = 34) enrolled between March and September 2012. Importantly all subjects returned to duty and did not require evacuation. Subjects were evaluated acutely 0-7 days after injury at two sites in Afghanistan and again 6-12 months later in the United States. Acute assessments revealed heightened post-concussive, post-traumatic stress, and depressive symptoms along with worse cognitive performance in subjects with traumatic brain injury. At 6-12 months follow-up, 63% of subjects with traumatic brain injury and 20% of controls had moderate overall disability. Subjects with traumatic brain injury showed more severe neurobehavioural, post-traumatic stress and depression symptoms along with more frequent cognitive performance deficits and more substantial headache impairment than control subjects. Logistic regression modelling using only acute measures identified that a diagnosis of traumatic brain injury, older age, and more severe post-traumatic stress symptoms provided a good prediction of later adverse global outcomes (area under the receiver-operating characteristic curve = 0.84). Thus, US military personnel with concussive blast-related traumatic brain injury in Afghanistan who returned to duty still fared quite poorly on many clinical outcome measures 6-12 months after injury. Poor global outcome seems to be largely driven by psychological health measures, age, and traumatic brain injury status. The effects of early interventions and longer term implications of these findings are unknown. © The Author (2015). Published by Oxford University Press on behalf of the Guarantors of Brain. All

Post-traumatic stress disorder due to childbirth: the aftermath.

Childbirth qualifies as an extreme traumatic stressor that can result in post-traumatic stress disorder. The reported prevalence of post-traumatic stress disorder after childbirth ranges from 1.5% to 6%. The aim of this phenomenologic study was to describe the essence of mothers' experiences of post-traumatic stress disorder after childbirth. The qualitative research design used for this study was descriptive phenomenology. The main recruitment approach was via the Internet through the help of Trauma and Birth Stress, a charitable trust in New Zealand. Purposive sampling was used and resulted in 38 mothers participating from the countries of New Zealand, the United States, Australia, and the United Kingdom. The participants were asked to describe their experiences with post-traumatic stress disorder after childbirth. Their stories were analyzed using Colaizzi's method of data analysis. Mothers with post-traumatic stress disorder attributable to childbirth struggle to survive each day while battling terrifying nightmares and flashbacks of the birth, anger, anxiety, depression, and painful isolation from the world of motherhood. This glimpse into the lives of mothers with post-traumatic stress disorder attributable to childbirth provides an impetus to increase research efforts in this neglected area.

It has been recently shown that enriched environment led to a significant benefit in learning and retention of visual-spatial memory, being able to reverse the cognitive impairment generated by undernourishment and recurrent seizures. We investigated the hippocampal morphological effects of recurrent seizures and undernourishment early in life in Wistar rats and the possible benefits produced by the enriched environment in these conditions. The morphological parameters stereologically evaluated were hippocampal volume, thickness of pyramidal stratum of the CA1 subfield and neuronal and glial densities in the same subfield. Male Wistar rats were divided into eight groups including nourished, nourished+enriched environment, nourished+recurrent seizures, nourished+recurrent seizures+enriched environment, undernourished, undernourished+enriched environment, undernourished+recurrent seizures and undernourished+recurrent seizures+enriched environment. Undernourishment model consisted in nutritional deprivation regimen from post-natal day 2 (P2) to P15. From P8 to P10, recurrent seizures group were induced by flurothyl three times per day. Enriched environment groups were exposed between P21 and P51. Our main findings were: (1) animals submitted to the enriched environment showed an increased hippocampal volume; (2) enriched environment promotes increases in the thickness of the pyramidal layer in hippocampal CA1 subfield in animals nourished and undernourished with recurrent seizures; (3) undernourishment during early development decreased neuronal density in CA1 and CA3 subfields. Our findings show that these three conditions induces important changes in hippocampal morphology, the most deleterious changes are induced by undernourishment and recurrent seizures, while more beneficial morphological changes are produced by enriched environment.

Summary Purpose To determine whether AMPA receptor (AMPAR) antagonist NBQX can prevent early mTOR pathway activation and long-term sequelae following neonatal seizures in rats, including later-life spontaneous recurrent seizures, CA3 mossy fiber sprouting, and autistic-like social deficits. Methods Long-Evans rats experienced hypoxia-induced neonatal seizures (HS) at postnatal day (P)10. NBQX (20 mg/kg) was administered immediately following HS (every 12h x 4 doses). 12h post-HS, we assessed mTOR activation marker phosphorylated p70-S6 kinase (p-p70S6K) in hippocampus and cortex of vehicle (HS+V) or NBQX-treated post-HS rats (HS+N) versus littermate controls (C+V). Spontaneous seizure activity was compared between groups by epidural cortical electroencephalography (EEG) at P70-100. Aberrant mossy fiber sprouting was measured using Timm staining. Finally, we assessed behavior between P30-38. Key findings Post-seizure NBQX treatment significantly attenuated seizure-induced increases in p-P70S6K in the hippocampus (p<0.01) and cortex (p<0.001). While spontaneous recurrent seizures increased in adulthood in HS+V rats compared to controls (3.22±1seizures/hour; p=0.03), NBQX significantly attenuated later-life seizures (0.14±0.1 seizures/hour; p=0.046). HS+N rats showed less aberrant mossy fiber sprouting (115±8.0%) than vehicle-treated post-HS rats (174±10%, p=0.004), compared to controls (normalized to 100%). Finally, NBQX treatment prevented alterations in later-life social behavior; post-HS rats showed significantly decreased preference for a novel over a familiar rat (71.0±12 sec) compared to controls (99.0±15.6 sec; p<0.01), while HS+N rats showed social novelty preference similar to controls (114.3±14.1 sec). Significance Brief NBQX administration during the 48 hours post-seizure in P10 Long-Evans rats suppresses transient mTOR pathway activation and attenuates spontaneous recurrent seizures, social preference deficits and mossy fiber sprouting observed in

Assessment of the usefulness of magnetic resonance brain imaging in patients presenting with acute seizures.

Magnetic Resonance Imaging (MRI) is increasingly available as a tool for assessment of patients presenting to acute services with seizures. We set out to prospectively determine the usefulness of early MRI brain in a cohort of patients presenting with acute seizures. We examined the MR imaging studies performed in patients admitted solely because of acute seizures to Cork University Hospital over a 12-month period. The main aim of the study was to determine if the MRI established the proximate cause for the patient's recent seizure. We identified 91 patients who underwent MRI brain within 48 h of admission for seizures. Of the 91 studies, 51 were normal (56 %). The remaining 40 studies were abnormal as follows: microvascular disease (usually moderate/severe) (n = 19), post-traumatic gliosis (n = 7), remote symptomatic lesion (n = 6), primary brain tumour (n = 5), venous sinus thrombosis (n = 3), developmental lesion (n = 3), post-surgical gliosis (n = 3) and single cases of demyelination, unilateral hippocampal sclerosis, lobar haemorrhage and metastatic malignant melanoma. Abnormalities in diffusion-weighted sequences that were attributable to prolonged ictal activity were seen in nine patients, all of who had significant ongoing clinical deficits, most commonly delirium. Of the 40 patients with abnormal MRI studies, seven patients had unremarkable CT brain. MR brain imaging revealed the underlying cause for acute seizures in 44 % of patients. CT brain imaging failed to detect the cause of the acute seizures in 19 % of patients in whom subsequent MRI established the cause. This study emphasises the importance of obtaining optimal imaging in people admitted with acute seizures.

Between 9 and 44% of women experience giving birth as traumatic, and 3% of women develop a post-traumatic stress disorder following childbirth. Knowledge on risk factors is abundant, but studies on treatment are limited. This study aimed to present an overview of means to prevent traumatic birth experiences and childbirth-related post-traumatic stress disorder. Major databases [Cochrane; Embase; PsycINFO; PubMed (Medline)] were searched using combinations of the key words and their synonyms. After screening titles and abstracts and reading 135 full-text articles, 13 studies were included. All evaluated secondary prevention, and none primary prevention. Interventions included debriefing, structured psychological interventions, expressive writing interventions, encouraging skin-to-skin contact with healthy newborns immediately postpartum and holding or seeing the newborn after stillbirth. The large heterogeneity of study characteristics precluded pooling of data. The writing interventions to express feelings appeared to be effective in prevention. A psychological intervention including elements of exposure and psycho-education seemed to lead to fewer post-traumatic stress disorder symptoms in women who delivered via emergency cesarean section. No research has been done on primary prevention of traumatic childbirth. Research on secondary prevention of traumatic childbirth and post-traumatic stress disorder following delivery provides insufficient evidence that the described interventions are effective in unselected groups of women. In certain subgroups, results are inhomogeneous. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

This case presentation highlights important principles in the management of post-traumatic diaphragmatic hernia. A suggestive history should prompt early diagnosis even if the patient appears well. The chest radiograph, although not pathognomonic, is extremely useful in the detection of diaphragmatic hernia if accurately interpreted. Herniated bowel is at high risk of strangulation, especially in the presence of a 'ribbon sign'. Delayed operative intervention can prove fatal.

The purpose of this study was to examine the relationship between peri-ictal EEG activity, surgical outcome, and extent of seizure propagation in a sample of pediatric epilepsy patients. Intracranial EEG recordings were obtained from 19 patients (mean age = 11.4 years, range = 3-20 years) with 57 seizures used for analysis (mean = 3.0 seizures per patient). For each seizure, 3-min segments were extracted from adjacent pre-ictal and post-ictal epochs. To compare physiology of the epileptic network between epochs, we calculated the relative delta power (Δ) using discrete Fourier transformation and constructed functional networks based on broadband connectivity (conn). We investigated differences between the pre-ictal (Δ pre , conn pre ) and post-ictal (Δ post , conn post ) segments in focal-network (i.e., confined to seizure onset zone) versus distributed-network (i.e., diffuse ictal propagation) seizures. Distributed-network (DN) seizures exhibited increased post-ictal delta power and global EEG connectivity compared to focal-network (FN) seizures. Following DN seizures, patients with seizure-free outcomes exhibited a 14.7% mean increase in delta power and an 8.3% mean increase in global connectivity compared to pre-ictal baseline, which was dramatically less than values observed among seizure-persistent patients (29.6% and 47.1%, respectively). Post-ictal differences between DN and FN seizures correlate with post-operative seizure persistence. We hypothesize that post-ictal deactivation of subcortical nuclei recruited during seizure propagation may account for this result while lending insights into mechanisms of post-operative seizure recurrence.

Stressful life events (SLEs) may elicit positive psychosocial change among youth, referred to as Post-traumatic Growth (PTG). We assessed types of SLEs experienced, degree to which participants reported PTG, and variables predicting PTG across 24 months among a sample of high risk, ethnically diverse early emerging adults. Participants were recruited from alternative high schools ( n = 564; mean age=16.8; 65% Hispanic). Multi-level regression models were constructed to examine the impact of environmental (SLE quantity, severity) and personal factors (hedonic ability, perceived stress, developmental stage, future time orientation) on a composite score of PTG. The majority of participants reported positive changes resulted from their most life-altering SLE of the past two years. Predictors of PTG included fewer SLEs, less general stress, having a future time perspective, and greater identification with the developmental stage of Emerging Adulthood. Findings suggest intervention targets to foster positive adaptation among early emerging adults who experience frequent SLEs.

Pathophysiological links between traumatic brain injury and post-traumatic headaches

Ruff, Robert L.; Blake, Kayla

2016-01-01

This article reviews possible ways that traumatic brain injury (TBI) can induce migraine-type post-traumatic headaches (PTHs) in children, adults, civilians, and military personnel. Several cerebral alterations resulting from TBI can foster the development of PTH, including neuroinflammation that can activate neural systems associated with migraine. TBI can also compromise the intrinsic pain modulation system and this would increase the level of perceived pain associated with PTH. Depression and anxiety disorders, especially post-traumatic stress disorder (PTSD), are associated with TBI and these psychological conditions can directly intensify PTH. Additionally, depression and PTSD alter sleep and this will increase headache severity and foster the genesis of PTH. This article also reviews the anatomic loci of injury associated with TBI and notes the overlap between areas of injury associated with TBI and PTSD. PMID:27635228

The present study aims to examine the relationship between trait resilience and virtues in the context of trauma. A total of 537 participants who attended the preliminary investigation and completed the Life Events Checklist were screened. Of these participants, 142 suffered from personal traumatic experiences in the past year; these individuals were qualified and invited to respond to online questionnaires to assess trait resilience, virtues (i.e., Conscientiousness, Vitality, and Relationship), post-traumatic stress disorder (PTSD) symptoms, and post-traumatic growth (PTG). The following questionnaires were used: Connor-Davidson Resilience Scale-Revised, Chinese Virtues Questionnaire, PTSD Checklist-Specific, and Post-traumatic Growth Inventory-Chinese. Only 95 participants who manifested self-reported PTSD symptoms and PTG were involved in the current analyses. Trauma was positively and significantly correlated with PTSD in the current sample. Results indicated that trait resilience was positively associated with virtues and PTG; by contrast, PTSD scores were negatively but not significantly related to most of these factors. The three virtues contributed to PTG to a greater extent than trait resilience in non-PTSD and PTSD groups. However, trait resilience remained a significant predictor in the PTSD group even when the three virtues were controlled. The relationship between trait resilience and PTG was moderated by PTSD type (non-PTSD group vs. PTSD group). Our results further suggested that trait resilience and virtues were conceptually related but functionally different constructs. Trait resilience and virtues are positively related; thus, these factors contributed variances to PTG in the context of trauma; however, trait resilience is only manifested when virtues are controlled and when individuals are diagnosed as PTSD. Furthermore, implications and limitations of this study are discussed. PMID:25932954

Neurotherapy of Traumatic Brain Injury/Post-Traumatic Stress Symptoms in Vietnam Veterans.

Previous report suggested the beneficial effects of an adaptation of the Flexyx Neurotherapy System (FNS) for the amelioration of mixed traumatic brain injury/post-traumatic stress symptoms in veterans of the Afghanistan and Iraq wars. As a novel variant of electroencephalograph biofeedback, FNS falls within the bioenergy domain of complementary and alternative medicine. Rather than learning voluntary control over the production/inhibition of brain wave patterns, FNS involves offsetting stimulation of brain wave activity by means of an external energy source, specifically, the conduction of electromagnetic energy stimulation via the connecting electroencephalograph cables. Essentially, these procedures subliminally induce strategic distortion of ongoing brain wave activity to presumably facilitate resetting of more adaptive patterns of activity. Reported herein are two cases of Vietnam veterans with mixed traumatic brain injury/post-traumatic stress symptoms, each treated with FNS for 25 sessions. Comparisons of pre- and post-treatment questionnaire assessments revealed notable decreases for all symptoms, suggesting improvements across the broad domains of cognition, pain, sleep, fatigue, and mood/emotion, including post-traumatic stress symptoms, as well as for overall activity levels. Findings suggest FNS treatment may be of potential benefit for the partial amelioration of symptoms, even in some individuals for whom symptoms have been present for decades.

To quantify the risk of unprovoked seizures after traumatic brain injury (TBI) METHODS: We used the Stockholm Incidence Registry on Epilepsy to carry out a population-based case-control study, including 1,885 cases with incident unprovoked seizures from September 1, 2000 through August 31, 2008, together with 15,080 matched controls. Information of prior hospitalizations for TBI was obtained through record linkage with the Swedish National Inpatient Registry for the period 1980-2008. Relative risks (RRs) for unprovoked seizures were estimated after various TBI diagnoses, and influences of TBI severity and time since trauma were studied in detail. After hospitalization for mild TBI, the RR was 2.0 (95% confidence interval [CI] 1.5-2.7). The RR was higher after brain contusion (5.9, 95% CI 2.4-15.0) or intracranial hemorrhage (ICH) (4.5, 95% CI 2.2-9.0), whereas a combination of both diagnoses led to a further sevenfold increase in RR (42.6, 95% CI 12.2-148.5). The risk was greatest during the first 6 months after severe TBI (RR 48.9, 95% CI 10.9-218.9) or mild TBI (RR 8.1, 95% CI 3.1-21.7), but was still elevated >10 years after any TBI. Herein we present a large population-based case-control study on TBI as a risk factor for unprovoked epileptic seizures, including cases of all ages with individually validated seizure diagnoses. The risk for epileptic seizures was substantially increased after TBI, especially during the first 6 months after the injury and in patients with a combination of ICH and brain contusion.

This study used ambulatory polysomnography (PSG) to investigate post-traumatic nightmares of post-traumatic stress disorder (PTSD). The key research question was whether post-traumatic nightmares occur in both rapid eye movement (REM) and non-REM sleep, and if so, whether nightmares in each sleep stage differed in content, phenomenology, and heart rate response. Underlying sleep disorders were investigated in an exploratory way. Thirty-five treatment-seeking veterans, current serving military members, and emergency service personnel undertook full PSG using the Compumedics (Melbourne, Australia) SomtePSG V1 system, during an inpatient psychiatric admission. The PSG recording included an event button to be pressed when a nightmare occurred, allowing us to determine the stage of sleep, changes in heart rate, and associated sleep events. The content and phenomenological features of participants' nightmares were recorded. Of the 35 participants, 29 reported a nightmare during their sleep study, but only 21 pressed the event button and could recall the content of one or more nightmare. This yielded sleep and nightmare data for 24 nightmares. Of the 24, 10 nightmares arose from REM sleep and 14 from non-REM (stages N1 and N2). Seven were accurate trauma replays and 17 were non-replay or a mixture of replay and non-replay. Most nightmares were associated with respiratory or leg movement events and increase in heart rate on awakening. Post-traumatic nightmares of PTSD occur in both REM and non-REM sleep and are commonly associated with other sleep disturbances. These findings have important treatment implications. © Sleep Research Society 2017. Published by Oxford University Press on behalf of the Sleep Research Society. All rights reserved.

It is unclear which specific symptoms of post-traumatic stress disorder are related to poor perceived quality of life. To investigate the influence of post-traumatic stress disorder symptomatology on quality of life in traumatic injury survivors. Traumatic injury survivors completed questionnaires on post-traumatic stress disorder symptomatology and quality of life at 3 months ( n = 987), 12 months ( n = 862), 24 months ( n = 830) and 6 years ( n = 613) post trauma. Low quality of life was reported by 14.5% of injury survivors at 3 months and 8% at 6 years post event. The post-traumatic stress disorder symptom clusters that contributed most to poor perceived quality of life were numbing and arousal, the individual symptoms that contributed most were anger, hypervigilance and restricted affect. There was variability in the quality of life of traumatic injury survivors in the 6 years following trauma and a consistent proportion reported low quality of life. Early intervention to reduce anger, hypervigilance and restricted affect symptoms may provide a means to improving the quality of life of traumatic injury survivors.

Early diagnosis of complications after severe trauma by specific biomarkers remains difficult. Identify potential new biomarkers for early diagnosis of post-traumatic complications. Mice underwent pressure-controlled hemorrhage or sham procedure. Four hours later, genome-wide expression of isolated Kupffer cells was compared with controls using Affymetrix-Genechip-Expression-Analysis and real-time-PCR. Expression analysis and real-time-PCR revealed a significant increase of gene expression of Cxcl10, Il4ra, Csf2rb2, Lcn2, and Gbp5. Cxcl10, Il4ra, Csf2rb2, Lcn2, and Gbp5 might represent new biomarkers for early diagnosis of post-traumatic complications, if they are linked to the development of post-traumatic complications.

Objective Traumatic brain injury (TBI) causes substantial morbidity and mortality in children. Post-traumatic seizures (PTS) may worsen outcomes after TBI. PTS risk factors are incompletely understood. Our objective was to clarify PTS risk factors in a large cohort of children with severe TBI. Design Retrospective cohort study of a probabilistically linked dataset from the National Trauma Data Bank (NTDB) and the Pediatric Health Information Systems (PHIS) database, 2007–2010 Setting 29 U.S. children’s hospitals Patients 2,122 children (age < 18 years old at admission) with linked NTDB and PHIS records, severe (Emergency Department [ED] Glasgow Coma Scale [GCS] < 8) TBI, hospital length of stay > 24 hours, and non-missing disposition Interventions None Measurements and Main Results The outcome was PTS, identified using validated ICD-9-CM diagnosis codes. Pre-specified candidate predictors of PTS included age, injury mechanism, ED GCS, intracranial hemorrhage type, hypoxia, hypotension, and cardiac arrest. PTS were diagnosed in 25.2% of children with severe TBI. In those without abuse/assault or subdural hemorrhage (SDH), the PTS rate varied between 36.6% in those < 2 years old and 16.4% in those 14–17 years old. Age, abusive mechanism, and subdural hemorrhage (SDH) are each significant predictors of PTS. The risk of PTS has a complex relationship with these predictors. The estimated odds of PTS decrease with advancing age, OR = 0.929 (0.905, 0.954) per additional year of age with no abuse/assault and no SDH; OR = 0.820 (0.730, 0.922) per additional year of age when abuse and SDH are present. An infant with accidental TBI and SDH has approximately the same estimated probability of PTS as an abused infant without SDH, 47% (95% CI: 39%, 55%) versus 50% (95% CI: 41%, 58%), P = 0.69. The triad of young age, injury by abuse/assault, and SDH confers the greatest estimated probability for PTS, 60% (95% CI: 53%, 66%). Conclusions PTS risk in children with severe TBI

Electrophysiological biomarkers of epileptogenicity after traumatic brain injury.

PubMed

2018-06-05

Post-traumatic epilepsy is the architype of acquired epilepsies, wherein a brain insult initiates an epileptogenic process culminating in an unprovoked seizure after weeks, months or years. Identifying biomarkers of such process is a prerequisite for developing and implementing targeted therapies aimed at preventing the development of epilepsy. Currently, there are no validated electrophysiological biomarkers of post-traumatic epileptogenesis. Experimental EEG studies using the lateral fluid percussion injury model have identified three candidate biomarkers of post-traumatic epileptogenesis: pathological high-frequency oscillations (HFOs, 80-300 Hz); repetitive HFOs and spikes (rHFOSs); and reduction in sleep spindle duration and dominant frequency at the transition from stage III to rapid eye movement sleep. EEG studies in humans have yielded conflicting data; recent evidence suggests that epileptiform abnormalities detected acutely after traumatic brain injury carry a significantly increased risk of subsequent epilepsy. Well-designed studies are required to validate these promising findings, and ultimately establish whether there are post-traumatic electrophysiological features which can guide the development of 'antiepileptogenic' therapies.

U.S. Army mortuary affairs (MA) soldiers experience stressors of deployment and exposure to the dead, increasing risk for post-traumatic stress and depression. This study examines Troop Education for Army Morale, a postdeployment early intervention based on Psychological First Aid. MA soldiers (N = 126) were randomized to intervention or comparison groups 1-month postdeployment. Intervention sessions were held at 2, 3, 4, and 7 months. Assessments of post-traumatic stress disorder (PTSD), depression, and quality of life (QOL) were conducted at 1, 2, 3, 4, 7, and 10 months for both groups. At baseline, 25.0% of the total sample had probable PTSD (17-item PTSD Checklist M = 35.4, SD = 16.9) and 23.6% had probable depression (9-item Patient Health Questionnaire Depression Scale M = 7.8, SD = 6.9). Over 10 months, PTSD and depression symptoms decreased and QOL improved for the total sample. At study conclusion, intervention and comparison groups were not different. Intervention group males showed a transient symptom increase at 2 to 3 months. Males attended fewer intervention sessions than females. Lower attendance was associated with more symptoms and lower QOL. Higher attendance was associated with greater intervention benefits. Findings highlight the need for better understanding postdeployment interventions and facilitating attendance. Further intervention for MA soldiers is indicated.

2015-01-01

Summary Post-traumatic stress disorder occurs in people exposed to life-threatening trauma. GPs may be seeing more patients with post-traumatic stress disorder as military personnel return from overseas deployments. The condition can present in various ways. To reduce the likelihood of missed or delayed diagnosis GPs can screen at-risk populations. A comprehensive assessment is recommended. Specialist referral may be required, particularly if there are other mental health problems. Trauma-focused psychological therapies should be offered as the first line of treatment for post-traumatic stress disorder. Usually 8–12 sessions are needed for a therapeutic effect. If drug treatment is needed, selective serotonin reuptake inhibitors are the first line. Other drugs used in post-traumatic stress disorder include antipsychotics, anticonvulsants and prazosin.

2010-01-01

Objective Develop a method for automatic detection of seizures prior to or immediately after clinical onset using features derived from scalp EEG. Methods This detection method is patient-specific. It uses recurrent neural networks and a variety of input features. For each patient we trained and optimized the detection algorithm for two cases: 1) during the period immediately preceding seizure onset, and 2) during the period immediately following seizure onset. Continuous scalp EEG recordings (duration 15 – 62 h, median 25 h) from 25 patients, including a total of 86 seizures, were used in this study. Results Pre-onset detection was successful in 14 of the 25 patients. For these 14 patients, all of the testing seizures were detected prior to seizure onset with a median pre-onset time of 51 sec and false positive rate was 0.06/h. Post-onset detection had 100% sensitivity, 0.023/hr false positive rate and median delay of 4 sec after onset. Conclusions The unique results of this study relate to pre-onset detection. Significance Our results suggest that reliable pre-onset seizure detection may be achievable for a significant subset of epilepsy patients without use of invasive electrodes. PMID:20461014

There is evidence that traumatic birth experiences are associated with psychological impairments. This study aimed to estimate the prevalence of childbirth-related post-traumatic stress symptoms and its obstetric and perinatal risk factors among a sample of Iranian women. This was a cross-sectional study carried out in Bushehr, Iran during a 3-months period from July to September 2009. Data were collected from all women attending eleven healthcare centers for postnatal care 6 to 8 weeks after childbirth. Those who had a traumatic delivery were identified and entered into the study. In order to assess childbirth-related post-traumatic stress, the Post-traumatic Symptom Scale-Interview (PSS-I) was administered. Data on demographic, obstetric and perinatal characteristics also were collected. Multivariate logistic regression was performed to examine the association between childbirth-related post-traumatic stress and demographic and obstetric and perinatal variables. In all, 400 women were initially evaluated. Of these, 218 women (54.5%) had a traumatic delivery and overall, 80 women (20%) were found to be suffering from post-partum post-traumatic stress disorder (PTSD). Multiple logistic regression analysis revealed that post-partum PTSD was associated with educational level, gestational age at delivery, number of prenatal care visits, pregnancy complications, pregnancy intervals, labor duration, and mode of delivery. The findings indicated that the prevalence of traumatic birth experiences and post-partum PTSD were relatively high among Iranian women. The findings also indicated that obstetric and perinatal variables were independently the most significant contributing factors to women's post-partum PTSD. It seems that a better perinatal care and supportive childbirth might help to reduce the burden of post-partum PTSD among this population.

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) presents a distinct clinical course of biphasic seizures and impaired consciousness. These symptoms are followed by reduced diffusion in the subcortical white matter on magnetic resonance imaging that is typically observed between 3 and 9 days after illness onset. Here, we report two cases of traumatic head injury with clinical and radiological features similar to those for AESD. The similarities between our cases and AESD may be useful in understanding the pathogenesis of AESD. Copyright © 2013 The Japanese Society of Child Neurology. Published by Elsevier B.V.

2015-06-01

Nursing students in the present sample who have experienced childhood adversity have a certain level of post-traumatic growth. If introduced into nursing curricula, emotional intelligence interventions may increase emotional coping resources and enhance social skills for nurses, which may benefit their long-term occupational health. As researchers consider personal resilience a strategy for responding to workplace adversity in nurses, resilience building should be incorporated into nursing education. This is a preliminary study that may guide future investigations of the curvilinear relationship rather than linear relationship between post-traumatic growth and positive factors in the special sample of nursing students. Resilience, emotional intelligence and post-traumatic growth may benefit nursing students' careers and personal well-being in clinical work. Developing both their emotional intelligence and resilience may assist their individual post-traumatic growth and enhance their ability to cope with clinical stress. To investigate the relationships among post-traumatic growth, emotional intelligence and psychological resilience in vocational school nursing students who have experienced childhood adversities, a cross-sectional research design with anonymous questionnaires was conducted and self-report data were analysed. The Childhood Adversities Checklist (Chinese version), Posttraumatic Growth Inventory, Emotional Intelligence Scale and the 10-item Connor-Davidson Resilience Scale were used. Survey data were collected from 202 Chinese vocational school nursing students during 2011. Post-traumatic growth was associated with emotional intelligence and psychological resilience. Results indicated a curvilinear relationship between emotional intelligence and post-traumatic growth, and between psychological resilience and post-traumatic growth. Moderate-level emotional intelligence and psychological resilience were most associated with the greatest levels of growth

Population-based data on the prevalence, correlates, and treatment utilization of post-traumatic stress disorder by gender and veteran status are limited. With changes in post-traumatic stress disorder diagnostic criteria in 2013, current information from a uniform data source is needed. This was a secondary analysis of the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III, which consisted of in-person interviews that were conducted with a representative sample of U.S. adults. The Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-5 Version was used to assess past-year and lifetime post-traumatic stress disorder among veterans (n=3,119) and civilians (n=32,982). Data were analyzed from January to March 2017. Adjusting for age and race/ethnicity, women veterans reported the highest rates of lifetime and past-year post-traumatic stress disorder (13.4%, 95% CI=8.8%, 17.9%, and 11.7%, 95% CI=7.1%, 16.4%) compared with women civilians (8.0%, 95% CI=7.4%, 8.6%, and 6.0%, 95% CI=5.5%, 6.6%); men veterans (7.7%, 95% CI=6.5%, 8.8%, and 6.7%, 95% CI=5.7%, 7.8%); and men civilians (3.4%, 95% CI=3.0%, 3.9%, and 2.6%, 95% CI=2.2%, 2.9%). Traumatic event exposure, correlates of lifetime post-traumatic stress disorder, and treatment seeking varied across subgroups. Men and women veterans were more likely than civilians to use a variety of treatment sources, with men civilians being least likely to seek treatment and men veterans exhibiting the longest delay in seeking treatment. Post-traumatic stress disorder is a common mental health disorder that varies by gender and veteran status. Women veterans' high rates of post-traumatic stress disorder highlight a critical target for prevention and intervention, whereas understanding treatment barriers for men veterans and civilians is necessary.

Predictors of birth-related post-traumatic stress symptoms: secondary analysis of a cohort study.

PubMed

Furuta, Marie; Sandall, Jane; Cooper, Derek; Bick, Debra

2016-12-01

This study aimed to identify factors associated with birth-related post-traumatic stress symptoms during the early postnatal period. Secondary analysis was conducted using data from a prospective cohort study of 1824 women who gave birth in one large hospital in England. Post-traumatic stress symptoms were measured by the Impact of Event Scale at 6 to 8 weeks postpartum. Zero-inflated negative binomial regression models were developed for analyses. Results showed that post-traumatic stress symptoms were more frequently observed in black women and in women who had a higher pre-pregnancy BMI compared to those with a lower BMI. Women who have a history of mental illness as well as those who gave birth before arriving at the hospital, underwent an emergency caesarean section or experienced severe maternal morbidity or neonatal complications also showed symptoms. Women's perceived control during labour and birth significantly reduced the effects of some risk factors. A higher level of perceived social support during the postnatal period also reduced the risk of post-traumatic stress symptoms. From the perspective of clinical practice, improving women's sense of control during labour and birth appears to be important, as does providing social support following the birth.

Many clinicians have noted that patients demonstrate a myopic refractive change following Traumatic Brain Injury (TBI). This apparent myopic shift disappears with cycloplegia, yet stubbornly reappears as soon as the pharmaceutical effect wears off. We propose that this shift is secondary to an irritative lesion that affects the parasympathetic innervation, resulting in ciliary body contracture. The dilemma for the clinician is whether to provide the immediate relief of clear distance vision by prescribing additional minus lenses, or to work toward attempting to re-establish the baseline refractive error. The natural history of post-traumatic pseudomyopia in our experience involves one of the following three courses: (1) a transient condition that will occasionally resolve; (2) the typical case, a recalcitrant condition that will resolve under cycloplegic intervention, but immediately return as the cycloplegic wears off; or (3) a less-common subgroup of patients who continue to show an increase in myopia over time. Our description of these cases demonstrates management strategies (including atropinization) to relax accommodative spasm, traditional vision therapy techniques aimed at loosening the accommodative system, and refractive corrections. Pseudomyopia is one of many ocular and behavioral sequelae following TBI. By understanding the natural course and potential management options for post-traumatic pseudomyopia, the clinician will be better prepared to deal with these challenging cases. Flexibility is required, since options that work with one patient may prove ineffective with another. Counseling the patient as to potential outcomes given the natural history of this condition helps establish more-realistic expectations by the patients being treated.

Neonatal seizures can lead to later life epilepsy and neurobehavioral deficits, and there are no treatments to prevent these sequelae. We previously showed that hypoxia-induced seizures in a neonatal rat model induce rapid phosphorylation of S831 and S845 sites of the AMPA receptor GluR1 subunit and later neuronal hyperexcitability and epilepsy, suggesting that seizure-induced post-translational modifications may represent a novel therapeutic target. To unambiguously assess the contribution of these sites, we examined seizure susceptibility in wild type mice versus transgenic knock-in mice with deficits in GluR1 S831 and S845 phosphorylation (GluR1 double phosphomutant (GluR1DPM) mice). Phosphorylation of the GluR1 S831 and S845 sites was significantly increased in the hippocampus and cortex following a single episode of pentyleneterazol (PTZ) induced seizures in postnatal day 9 (P9) wild type mouse pups, and that transgenic knock-in mice have a higher threshold and longer latencies to seizures. Like the rat, hypoxic seizures in P9 C57BL/6N wild type mice resulted in transient increases in GluR1 S831 and GluR1 S845 phosphorylation in cortex, and were associated with enhanced seizure susceptibility to later-life kainic acid induced seizures. In contrast, later-life seizure susceptibility following hypoxia-induced seizures was attenuated in GluR1 DPM mice, supporting a role for post-translational modifications in seizure-induced network excitability. Finally, human hippocampal samples from neonatal seizure autopsy cases also showed an increase in GluR1 S831 and S845, supporting the validation of this potential therapeutic target in human tissue.

Is Electroconvulsive Therapy a Treatment for Depression Following Traumatic Brain Injury?

Traumatic brain injury (TBI) can be caused by blunt or penetrating injury to the head. The pathophysiological evolution of TBI involves complex biochemical and genetic changes. Common sequelae of TBI include seizures and psychiatric disorders, particularly depression. In considering pharmacologic interventions for treating post-TBI depression, it is important to remember that TBI patients have a higher risk of seizures; therefore, the benefits of prescribing medications that lower the seizure threshold need to be weighed against the risk of seizures. When post-TBI depression is refractory to pharmacotherapy, electroconvulsive therapy (ECT) could provide an alternative therapeutic strategy. Data remain sparse on using ECT in this seizure-prone population, but three case reports demonstrated good outcomes. Currently, not enough evidence exists to provide clinical recommendations for using ECT for treating post-TBI depression, and more research is needed to generate guidelines on how best to treat depression in TBI patients. However, the preliminary data on using ECT in patients with TBI are promising. If proven safe, ECT could be a powerful tool to treat post-TBI depression. PMID:29707426

Secondary tics are those in which an aetiology justifying them can be found, as compared to idiopathic tics, which make up the majority, and the Gilles de la Tourette syndrome (SGT), which is, at the moment, of unknown origin. Of the possible aetiologies described as causing tics, craneo-encephalic trauma has been mentioned on very few occasions. We present a case of post-traumatic tics (verbal and neck) in a young man of 24, and review the published cases which can be considered to be of post-traumatic tics. We have found six cases of tics secondary to traumas, all craneo-encephalic, like ours (the one under study). The time interval between the blow and the appearance of the tic or tics varied between 2 weeks and 3 months. The absence of significant lesions seen in the complementary investigations make it impossible for us to discover the site of the lesion caused by the trauma. However, the presence in some cases of other tics before the trauma, and of family histories of tics, supports the idea of a genetic basis or predisposition to suffer this disorder.

To determine whether the absence of early epileptiform abnormalities predicts absence of later seizures on continuous EEG monitoring of hospitalized patients. We retrospectively reviewed 242 consecutive patients without a prior generalized convulsive seizure or active epilepsy who underwent continuous EEG monitoring lasting at least 18 hours for detection of nonconvulsive seizures or evaluation of unexplained altered mental status. The findings on the initial 30-minute screening EEG, subsequent continuous EEG recordings, and baseline clinical data were analyzed. We identified early EEG findings associated with absence of seizures on subsequent continuous EEG. Seizures were detected in 70 (29%) patients. A total of 52 patients had their first seizure in the initial 30 minutes of continuous EEG monitoring. Of the remaining 190 patients, 63 had epileptiform discharges on their initial EEG, 24 had triphasic waves, while 103 had no epileptiform abnormalities. Seizures were later detected in 22% (n = 14) of studies with epileptiform discharges on their initial EEG, vs 3% (n = 3) of the studies without epileptiform abnormalities on initial EEG (p < 0.001). In the 3 patients without epileptiform abnormalities on initial EEG but with subsequent seizures, the first epileptiform discharge or electrographic seizure occurred within the first 4 hours of recording. In patients without epileptiform abnormalities during the first 4 hours of recording, no seizures were subsequently detected. Therefore, EEG features early in the recording may indicate a low risk for seizures, and help determine whether extended monitoring is necessary.

Treatment of TBI remains a major unmet medical need, with 2.5 million new cases of traumatic brain injury (TBI) each year in Europe and 1.5 million in the USA. This single-center proof-of-concept preclinical study tested the hypothesis that pharmacologic neurostimulation with proconvulsants, either atipamezole, a selective α 2 -adrenoceptor antagonist, or the cannabinoid receptor 1 antagonist SR141716A, as monotherapy would improve functional recovery after TBI. A total of 404 adult Sprague-Dawley male rats were randomized into two groups: sham-injured or lateral fluid-percussion-induced TBI. The rats were treated with atipamezole (started at 30min or 7 d after TBI) or SR141716A (2min or 30min post-TBI) for up to 9 wk. Total follow-up time was 14 wk after treatment initiation. Outcome measures included motor (composite neuroscore, beam-walking) and cognitive performance (Morris water-maze), seizure susceptibility, spontaneous seizures, and cortical and hippocampal pathology. All injured rats exhibited similar impairment in the neuroscore and beam-walking tests at 2 d post-TBI. Atipamezole treatment initiated at either 30min or 7 d post-TBI and continued for 9 wk via subcutaneous osmotic minipumps improved performance in both the neuroscore and beam-walking tests, but not in the Morris water-maze spatial learning and memory test. Atipamezole treatment initiated at 7 d post-TBI also reduced seizure susceptibility in the pentylenetetrazol test 14 wk after treatment initiation, although it did not prevent the development of epilepsy. SR141716A administered as a single dose at 2min post-TBI or initiated at 30min post-TBI and continued for 9 wk had no recovery-enhancing or antiepileptogenic effects. Mechanistic studies to assess the α 2 -adrenoceptor subtype specificity of the disease-modifying effects of atipametzole revealed that genetic ablation of α 2A -noradrenergic receptor function in Adra2A mice carrying an N79P point mutation had antiepileptogenic effects

Post-traumatic stress disorder vs traumatic brain injury

2011-01-01

Post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) often coexist because brain injuries are often sustained in traumatic experiences. This review outlines the significant overlap between PTSD and TBI by commencing with a critical outline of the overlapping symptoms and problems of differential diagnosis. The impact of TBI on PTSD is then described, with increasing evidence suggesting that mild TBI can increase risk for PTSD. Several explanations are offered for this enhanced risk. Recent evidence suggests that impairment secondary to mild TBI is largely attributable to stress reactions after TBI, which challenges the long-held belief that postconcussive symptoms are a function of neurological insult This recent evidence is pointing to new directions for treatment of postconcussive symptoms that acknowledge that treating stress factors following TBI may be the optimal means to manage the effects of many TBIs, PMID:22034252

Regrettably, exposure to trauma is common worldwide, and can have serious adverse psychological results. The introduction of the notion of post-traumatic stress disorder has led to increasing medicalisation of the problem. This awareness has helped popular acceptance of the reality of post-traumatic psychiatric sequelae, which has boosted research into the pathogenesis of the disorder, leading to improved pharmacological and psychological management. The subjective experience of trauma and subsequent expression of symptoms vary considerably over space and time, and we emphasise that not all psychological distress or psychiatric disorders after trauma should be termed post-traumatic stress disorder. There are limits to the medicalisation of distress and there is value in focusing on adaptive coping during and after traumas. Striking a balance between a focus on heroism and resilience versus victimhood and pathological change is a crucial and constant issue after trauma for both clinicians and society. In this Review we discuss the advantages and disadvantages of medicalising trauma response, using examples from South Africa, the Armed Services, and post-disaster, to draw attention to our argument.

To determine whether AMPA receptor (AMPAR) antagonist NBQX can prevent early mammalian target of rapamycin (mTOR) pathway activation and long-term sequelae following neonatal seizures in rats, including later-life spontaneous recurrent seizures, CA3 mossy fiber sprouting, and autistic-like social deficits. Long-Evans rats experienced hypoxia-induced neonatal seizures (HS) at postnatal day (P)10. NBQX (20 mg/kg) was administered immediately following HS (every 12 h × 4 doses). Twelve hours post-HS, we assessed mTOR activation marker phosphorylated p70-S6 kinase (p-p70S6K) in hippocampus and cortex of vehicle (HS + V) or NBQX-treated post-HS rats (HS + N) versus littermate controls (C + V). Spontaneous seizure activity was compared between groups by epidural cortical electroencephalography (EEG) at P70-100. Aberrant mossy fiber sprouting was measured using Timm staining. Finally, we assessed behavior between P30 and P38. Postseizure NBQX treatment significantly attenuated seizure-induced increases in p-p70S6K in the hippocampus (p < 0.01) and cortex (p < 0.001). Although spontaneous recurrent seizures increased in adulthood in HS + V rats compared to controls (3.22 ± 1 seizures/h; p = 0.03), NBQX significantly attenuated later-life seizures (0.14 ± 0.1 seizures/h; p = 0.046). HS + N rats showed less aberrant mossy fiber sprouting (115 ± 8.0%) than vehicle-treated post-HS rats (174 ± 10%, p = 0.004), compared to controls (normalized to 100%). Finally, NBQX treatment prevented alterations in later-life social behavior; post-HS rats showed significantly decreased preference for a novel over a familiar rat (71.0 ± 12 s) compared to controls (99.0 ± 15.6 s; p < 0.01), whereas HS + N rats showed social novelty preference similar to controls (114.3 ± 14.1 s). Brief NBQX administration during the 48 h postseizure in P10 Long-Evans rats suppresses transient mTOR pathway activation and attenuates spontaneous recurrent seizures, social preference deficits, and mossy

Background Although childhood adversities are known to predict increased risk of post-traumatic stress disorder (PTSD) after traumatic experiences, it is unclear whether this association varies by childhood adversity or traumatic experience types or by age. Aims To examine variation in associations of childhood adversities with PTSD according to childhood adversity types, traumatic experience types and life-course stage. Method Epidemiological data were analysed from the World Mental Health Surveys ( n = 27 017). Results Four childhood adversities (physical and sexual abuse, neglect, parent psychopathology) were associated with similarly increased odds of PTSD following traumatic experiences (odds ratio (OR) = 1.8), whereas the other eight childhood adversities assessed did not predict PTSD. Childhood adversity-PTSD associations did not vary across traumatic experience types, but were stronger in childhood-adolescence and early-middle adulthood than later adulthood. Conclusions Childhood adversities are differentially associated with PTSD, with the strongest associations in childhood-adolescence and early-middle adulthood. Consistency of associations across traumatic experience types suggests that childhood adversities are associated with generalised vulnerability to PTSD following traumatic experiences. © The Royal College of Psychiatrists 2017.

Developmental Timing of Childhood Physical and Sexual Maltreatment Predicts Adult Depression and Post-Traumatic Stress Symptoms.

Child physical and sexual maltreatment have emerged as documented risk factors for a wide range of health problems in adulthood, including depression and post-traumatic stress symptoms. Prior research focuses on generalized childhood adversities without accounting for how different critical details about the maltreatment may affect outcomes in adulthood. The present study examines the impact of two critical details, timing and type of child maltreatment, on depression and post-traumatic stress symptoms in adulthood. Participants ( N = 104) completed the Maltreatment and Abuse Chronology of Exposure scale (MACE) and the Inventory of Depression and Anxiety Scale-Second Version (IDAS-II). Hierarchical multiple regressions compared three different models of child maltreatment predictors and their differential utility for predicting depression and post-traumatic stress symptoms in adulthood: (a) number of child maltreatment experiences, (b) severity of child maltreatment, and (c) timing of child maltreatment. Results indicate that severity of child maltreatment and timing of child maltreatment are greater predictors for adult depression and post-traumatic stress symptoms than number of child maltreatment experiences. Compared with other developmental periods, early childhood sexual maltreatment experiences (5 years of age and below) and late childhood physical maltreatment experiences (13 years of age and above) were stronger predictors of adult depression and post-traumatic stress symptoms. Children maltreated during these age groups may be prioritized for prevention and intervention efforts, particularly when there are limited resources. Clinical interviews with maltreated children should also be expanded to include information about developmental timing and severity of maltreatment, which have ramifications for later health problems. Implications for assessment of maltreated children, prevention of adult depression and post-traumatic stress symptoms, and future

High incidence of necrotic and suppurative complications is feature of acute post-traumatic pancreatitis. Severe trauma of the pancreas and post-traumatic pancreatitis lead to depressurization of ductal system that requires adequate drainage of damaged area and retroperitoneal fat. 95 patients in group 1 received standardized treatment. The victims of the 2nd group (44 patients) were treated using immunoreactive therapy (roncoleukin) and octreotide (the dose depended on the severity of pancreatitis) at early stages. The efficacy of treatment was assessed based on clinical, laboratory and instrumental parameters. Regardless severity of pancreatic injury overall mortality in groups 1 and 2 was 41% and 20.5% respectively. The main causes of adverse outcomes are severe destructive pancreatitis, postnecrotic suppurative complications. Adequacy rather radicalism of surgery should be preferred for blunt pancreatic trauma management. Minimally invasive surgical techniques and new methods of biological hemostasis may be applied. Timely use of anti-enzymatic and immunoactive therapy reduces the risk of severe post-traumatic pancreatitis, suppurative complications and improves outcomes in patients with blunt pancreatic trauma.

Early Detection of Human Focal Seizures Based on Cortical Multiunit Activity

Approximately 50 million people in the world suffer from epileptic seizures. Reliable early seizure detection could bring significantly beneficial therapeutic alternatives. In recent decades, most approaches have relied on scalp EEG and intracranial EEG signals, but practical early detection for closed-loop seizure control remains challenging. In this study, we present preliminary analyses of an early detection approach based on intracortical neuronal multiunit activity (MUA) recorded from a 96-microelectrode array (MEA). The approach consists of (1) MUA detection from broadband field potentials recorded at 30 kHz by the MEA; (2) MUA feature extraction; (3) cost-sensitive support vector machine classification of ictal and interictal samples; and (4) Kalman-filtering postprocessing. MUA was here defined as the number of threshold crossing (spike counts) applied to the 300 Hz – 6 kHz bandpass filtered local field potentials in 0.1 sec time windows. MUA features explored in this study included the mean, variance, and Fano-factor, computed across the MEA channels. In addition, we used the leading eigenvalues of MUA spatial and temporal correlation matrices computed in 1-sec moving time windows. We assessed the seizure detection approach on out-of-sample data from one-participant recordings with six seizure events and 4.73-hour interictal data. The proposed MUA-based detection approach yielded a 100% sensitivity (6/6) and no false positives, and a latency of 4.17 ± 2.27 sec (mean ± SD) with respect to ECoG-identified seizure onsets. These preliminary results indicate intracortical MUA may be a useful signal for early detection of human epileptic seizures. PMID:25571313

Bereavement, post-traumatic stress and post-traumatic growth: through the lenses of positive psychology

2017-01-01

ABSTRACT Background: During the past decades we have learned a lot about the psychopathology that can be triggered from adversity, but our knowledge of the qualities developed and processes experienced by people who remain healthy despite having gone through trauma has been limited. A proposed area within positive psychology is the psychology of loss. Psychology of loss emphasizes the study of healthy individuals, the resources they use for adapting to loss, and the ways in which they can transform their losses into personal growth and strength. Under the theoretical umbrella of positive psychology, the construct of post-traumatic growth has also received increased scholarly attention in recent years. Post-traumatic growth is a concept and a construct that reflects the ‘positive psychological change experienced as a result of the struggle with highly challenging life circumstances’ (Tedeschi & Calhoun, 2004). Numerous empirical studies have described the phenomenon after various traumas, including traumatic bereavement, even among children and adolescents (Kilmer et al., 2009). Objective: The qualitative study presented was conducted in the UK, where eight women were interviewed after losing their first child perinatally. This type of bereavement constitutes a traumatic loss and although there is a plethora of research focusing on the resulting parental psychopathology, research on adaptive grief resolution and post-traumatic growth is scarce. Method: The research question was ‘How mothers experience personal growth after a perinatal loss’ and the research methodology employed was interpretative phenomenological analysis (Smith, Flowers, & Larkin, 2009). Results: The analysis revealed four superordinate themes. The first mainly presented the traumatic quality of this type of bereavement and included subthemes such as iatrogenic psychological trauma, while the second presented the multiple losses involved with emerging themes on the amputated object

Prognostication in the early stage of traumatic coma is a common challenge in the neuro-intensive care unit. We report the unexpected recovery of functional milestones (i.e., consciousness, communication, and community reintegration) in a 19-year-old man who sustained a severe traumatic brain injury. The early magnetic resonance imaging (MRI) findings, at the time, suggested a poor prognosis. During the first year of the patient's recovery, MRI with diffusion tensor imaging and T2*-weighted imaging was performed on day 8 (coma), day 44 (minimally conscious state), day 198 (post-traumatic confusional state), and day 366 (community reintegration). Mean apparent diffusion coefficient (ADC) and fractional anisotropy values in the corpus callosum, cerebral hemispheric white matter, and thalamus were compared with clinical assessments using the Disability Rating Scale (DRS). Extensive diffusion restriction in the corpus callosum and bihemispheric white matter was observed on day 8, with ADC values in a range typically associated with neurotoxic injury (230-400 × 10(-6 )mm(2)/s). T2*-weighted MRI revealed widespread hemorrhagic axonal injury in the cerebral hemispheres, corpus callosum, and brainstem. Despite the presence of severe axonal injury on early MRI, the patient regained the ability to communicate and perform activities of daily living independently at 1 year post-injury (DRS = 8). MRI data should be interpreted with caution when prognosticating for patients in traumatic coma. Recovery of consciousness and community reintegration are possible even when extensive traumatic axonal injury is demonstrated by early MRI.

Post-Traumatic Stress Symptoms in Pediatric Heart Transplant Recipients.

Traumatic experiences are not unusual in pediatric heart transplant (HT) recipients before and after transplantation. Post-traumatic stress symptoms (PTSS) present at the time of transplant evaluation and developing afterward occur with an unknown frequency. We sought to determine the burden of these symptoms in heart transplant patients. We reviewed 51 consecutive HTs between 2003-2007, including 40 primary transplants and 11 re-transplants. Symptoms were present in 17 of the 51 patients (34%) at the time of orthotopic heart transplantation evaluation. None met the criteria for full post traumatic stress disorder. Transplant complications were examined. Nineteen subjects of the total sample had rejection in the first year following transplant. Rejection rates in the first year was 41% for those with PTSS (7 of 17 patients) and 36% for those without (12 of 33 patients) (P=n.s). Of those patients presenting for a second heart transplant, 55% had PTSS at the time of transplant evaluation and/or the peritransplant period; whereas, (28%) undergoing a primary transplant had PTSS. In addition to symptoms resulting from the disease process leading to HT and other prior experiences, the HT itself seems to present a large psychiatric burden on patients. All patients need to be followed before and after HT for signs and symptoms related to PTSS. Future studies should be undertaken to determine if preventative detection and treatment of patients with these PTSS symptoms early can lead to better outcomes.

Symptoms of post-traumatic stress disorder are common in fibromyalgia patients. This study compared post-traumatic stress disorder symptoms in fibromyalgia patients and healthy controls and determined whether patient-control differences in post-traumatic stress disorder symptoms mediated differences in mental health. In all, 30 patients and 30 healthy controls completed questionnaires assessing symptoms of post-traumatic stress disorder and mental health. Fibromyalgia patients had greater symptoms of post-traumatic stress disorder and mental health than controls. Patient-control differences in mental health symptoms were fully or partially mediated by differences in post-traumatic stress disorder symptoms. Healthcare providers should understand the role of trauma as management of trauma symptoms may be one strategy for improving mental health.

The aim of the study is to study the prevalence and comorbidity of commonly occurring psychological symptoms in people exposed to Nepal mega earthquake in 2015 after a year of the event. A community based, cross sectional, descriptive study was carried out in Bhumlichaur area of Gorkha district, Nepal after around 14 months of the first major earthquake. We used self-reporting questionnaire 20, Post-traumatic stress disorder 8 and hospital anxiety and depression scale to screen for presence of symptoms of anxiety and depression or post-traumatic stress disorder in this population. The risk of having these disorders according to different socio-demographic variable was assessed by calculating odds ratio. All calculations were done using predictive and analytical software (PASW) version 16.0. A total of 198 participants were included in the final data analysis. The mean age of study participants was 35.13 years (SD=18.04). Borderline anxiety symptoms were found in 104 (52.5%) while significant anxiety symptoms were found in 40 (20%) of respondents. Borderline depressive symptoms were seen in 40 (20%) while significant depressive symptoms were seen in 16 (8%) of subjects. Around 27% (n= 53) of respondents were classified as having post-traumatic stress disorder. The prevalence of anxiety and depressive symptoms and post-traumatic stress disorder seems to be high even after one year in people exposed to earthquake.

To explore the roles of attachment and alexithymia in the severity of post-traumatic stress disorder symptoms and to specify the relationship between sub-dimensions of attachment, alexithymia and posttraumatic stress disorder symptoms in patients with first-time myocardial infarction in mainland China. Patients experiencing myocardial infarction have a risk of developing post-traumatic stress disorder symptoms. However, there have been few studies on the roles of attachment and alexithymia. A cross-sectional survey design. Ninety-seven patients participated in the assessment of post-traumatic stress disorder symptoms, attachment and alexithymia from June-December in 2012. To assess post-traumatic stress disorder symptoms and their correlates, we administered the Post-traumatic Stress Disorder Checklist-Civilian Version, the 20-item Toronto Alexithymia Scale and the Experiences in Close Relationships Scale 5-17 days after the remission of first myocardial infarction attack. Twenty-five (25·77%) patients met the criteria of posttraumatic stress disorder symptoms. Greater attachment anxiety and avoidance were associated with more severe posttraumatic stress disorder symptoms. Except for externally oriented thinking, all dimensions of alexithymia were significantly correlated with post-traumatic stress symptoms. In the regression model, attachment anxiety and difficulties identifying feelings were found to be predictive and the total regression equation explained 24·2% variance of posttraumatic stress disorder symptoms among myocardial infarction patients. First-time myocardial infarction patients were at risk of developing posttraumatic stress disorder symptoms. Attachment anxiety and difficulties identifying feelings were positively associated with posttraumatic stress disorder symptoms in the early stage of myocardial infarction rehabilitation. It is essential to evaluate the causal relationship between attachment, alexithymia and posttraumatic stress disorder

Symptoms of both depression and Post-Traumatic Stress Disorder (PTSD) are prevalent among first-time mothers following birth. However, the direction of the association between the two types of symptoms is unclear. Ninety six first-time mothers giving birth via vaginal delivery (N=38), emergency C-Section (N=27) and planned C-Section (N=21) were assessed for depression and PTSD twice: Six weeks post-partum and six-weeks later. Cross-lagged Structural Equation Modeling (SEM) analyses revealed a prospective effect of depressive symptoms on PTSD symptoms. No moderating factors were identified. A relatively modest sample size and only two assessment waves. An early detection and intervention with symptoms of post-partum depression might also prevent the development of PTSD symptoms.

Childbirth might be a traumatic event for some women. This study was conducted with the objective of investigating the prevalence of Post-Traumatic Stress Disorder (PTSD) following childbirth. The study was designed using a descriptive correlation scheme. The participants were selected from the women referred to the healthcare centers affiliated with Zahedan University of Medical Sciences, Zahedan, Iran. Personal interviews were conducted with 600 women who were 6-8 weeks postpartum and had been undergone to this center for postpartum and child care. One hundred and three (17. 2%) women had symptoms of PTSD following childbirth based on the PTSD Symptom Scale (PSS). The results of logistic regression analysis revealed a significant correlation between maternal occupation (P = 0.01), depression level (P < 0.001) and anxiety level (P < 0.001) with PTSD following childbirth. PTSD from childbirth occurs in some women. Early identification of risk factors should lead to early therapeutic intervention in the mothers at risk of PTSD.

This mail survey measured post-traumatic stress symptoms, spiritual and non-spiritual coping strategies, and positive spiritual outcomes following the tragedies of 9/11/01 in a national, random sample of 1,056 Presbyterians. Respondents reported mild to moderate degrees of re-experiencing and hyper-arousal symptoms of post-traumatic stress, unrelated to location or knowing someone involved. People experiencing high stress used greater frequency and variety of both spiritual and non-spiritual types of coping strategies. Positive spiritual outcomes were remarkably related to positive spiritual coping strategies, in contrast to no association with negative coping. This study illustrates the significant degree of post-traumatic stress experienced with vicarious exposure and a wide spectrum of coping strategies used following the major terrorist attacks.

Objective: To evaluate via a research literature survey the anterior neurological significance of decreased olfactory functioning following traumatic brain injuries. Materials and Methods: A computer literature review was performed to locate all functional neuro-imaging studies on patients with post-traumatic anosmia and other olfactory deficits. Results: A convergence of findings from nine functional neuro-imaging studies indicating evidence for reduced metabolic activity at rest or relative hypo-perfusion during olfactory activations. Hypo-activation of the prefrontal regions was apparent in all nine post-traumatic samples, with three samples yielding evidence of reduced activity in the temporal regions as well. Conclusions: The practical ramifications include the reasonable hypothesis that a total anosmic head trauma patient likely has frontal lobe involvement. PMID:21716782

Post-traumatic Stress Disorder and Cardiovascular Disease.

PubMed

Burg, Matthew M; Soufer, Robert

2016-10-01

Post-traumatic stress disorder (PTSD) is a disabling condition that develops consequent to trauma exposure such as natural disasters, sexual assault, automobile accidents, and combat that independently increases risk for early incident cardiovascular disease (CVD) and cardiovascular (CV) mortality by over 50 % and incident hypertension risk by over 30 %. While the majority of research on PTSD and CVD has concerned initially healthy civilian and military veteran samples, emerging research is also demonstrating that PTSD consequent to the trauma of an acute cardiac event significantly increases risk for early recurrence and mortality and that patient experiences in the clinical pathway that are related to the emergency department environment may provide an opportunity to prevent PTSD onset and thus improve outcomes. Future directions for clinical and implementation science concern broad PTSD and trauma screening in the context of primary care medical environments and the testing of PTSD treatments with CVD-related surrogates and endpoints.

Early Detection of Human Epileptic Seizures Based on Intracortical Local Field Potentials

2014-01-01

The unpredictability of re-occurring seizures dramatically impacts the quality of life and autonomy of people with epilepsy. Reliable early seizure detection could open new therapeutic possibilities and thus substantially improve quality of life and autonomy. Though many seizure detection studies have shown the potential of scalp electroencephalogram (EEG) and intracranial EEG (iEEG) signals, reliable early detection of human seizures remains elusive in practice. Here, we examined the use of intracortical local field potentials (LFPs) recorded from 4×4-mm2 96-microelectrode arrays (MEA) for early detection of human epileptic seizures. We adopted a framework consisting of (1) sampling of intracortical LFPs; (2) denoising of LFPs with the Kalman filter; (3) spectral power estimation in specific frequency bands using 1-sec moving time windows; (4) extraction of statistical features, such as the mean, variance, and Fano factor (calculated across channels) of the power in each frequency band; and (5) cost-sensitive support vector machine (SVM) classification of ictal and interictal samples. We tested the framework in one-participant dataset, including 4 seizures and corresponding interictal recordings preceding each seizure. The participant was a 52-year-old woman suffering from complex partial seizures. LFPs were recorded from an MEA implanted in the participant’s left middle temporal gyrus. In this participant, spectral power in 0.3–10 Hz, 20–55 Hz, and 125–250 Hz changed significantly between ictal and interictal epochs. The examined seizure detection framework provided an event-wise sensitivity of 100% (4/4) and only one 20-sec-long false positive event in interictal recordings (likely an undetected subclinical event under further visual inspection), and a detection latency of 4.35 ± 2.21 sec (mean ± std) with respect to iEEG-identified seizure onsets. These preliminary results indicate that intracortical MEA recordings may provide key signals to quickly

Post-traumatic hypopituitarism and fatigue.

Masel, Brent E; Zgaljardic, Dennis J; Forman, Jack

2017-10-01

Post-traumatic hypopituitarism (PTH) associated with chronic cognitive, psychiatric, and/or behavioural sequelae is common following moderate to severe traumatic brain injury (TBI). More specifically, due to a cascade of hormonal deficiencies secondary to PTH, individuals with TBI may experience debilitating fatigue that can negatively impact functional recovery, as it can limit participation in brain injury rehabilitation services and lead to an increase in maladaptive lifestyle practices. While the mechanisms underlying fatigue and TBI are not entirely understood, the current review will address the specific anatomy and physiology of the pituitary gland, as well as the association between pituitary dysfunction and fatigue in individuals with TBI.

Restless 'rest': intrinsic sensory hyperactivity and disinhibition in post-traumatic stress disorder.

Clancy, Kevin; Ding, Mingzhou; Bernat, Edward; Schmidt, Norman B; Li, Wen

Post-traumatic stress disorder is characterized by exaggerated threat response, and theoretical accounts to date have focused on impaired threat processing and dysregulated prefrontal-cortex-amygdala circuitry. Nevertheless, evidence is accruing for broad, threat-neutral sensory hyperactivity in post-traumatic stress disorder. As low-level, sensory processing impacts higher-order operations, such sensory anomalies can contribute to widespread dysfunctions, presenting an additional aetiological mechanism for post-traumatic stress disorder. To elucidate a sensory pathology of post-traumatic stress disorder, we examined intrinsic visual cortical activity (based on posterior alpha oscillations) and bottom-up sensory-driven causal connectivity (Granger causality in the alpha band) during a resting state (eyes open) and a passive, serial picture viewing state. Compared to patients with generalized anxiety disorder (n = 24) and healthy control subjects (n = 20), patients with post-traumatic stress disorder (n = 25) demonstrated intrinsic sensory hyperactivity (suppressed posterior alpha power, source-localized to the visual cortex-cuneus and precuneus) and bottom-up inhibition deficits (reduced posterior→frontal Granger causality). As sensory input increased from resting to passive picture viewing, patients with post-traumatic stress disorder failed to demonstrate alpha adaptation, highlighting a rigid, set mode of sensory hyperactivity. Interestingly, patients with post-traumatic stress disorder also showed heightened frontal processing (augmented frontal gamma power, source-localized to the superior frontal gyrus and dorsal cingulate cortex), accompanied by attenuated top-down inhibition (reduced frontal→posterior causality). Importantly, not only did suppressed alpha power and bottom-up causality correlate with heightened frontal gamma power, they also correlated with increased severity of sensory and executive dysfunctions (i.e. hypervigilance and impulse control

Ankle involvement by synovial chondromatosis is unusual. It is unknown whether a post-traumatic event to the ankle induces the formation and development of these lesions. Synovial osteochondromatosis associated with post-traumatic ankle events are rare but suggest trauma to the synovial tissues as being causative, although this has never been statistically confirmed owing to the lack of reports and frequency. We report a case of primary synovial osteochondromatosis involving the tibiotalar joint with painful symptoms after a history of ankle injury, including magnetic resonance imaging findings of this unusual condition.

Given that post-traumatic headache is one of the most prevalent and long-lasting post-concussion sequelae, causes significant morbidity, and might be associated with slower neurocognitive recovery, we sought to evaluate the use of concussion screening scores in a concussion clinic population to assess for post-traumatic headache. This is a retrospective cross-sectional study of 254 concussion patients from the New York University (NYU) Concussion Registry. Data on the headache characteristics, concussion mechanism, concussion screening scores were collected and analyzed. 72% of the patients had post-traumatic headache. About half (56.3%) were women. The mean age was 35 (SD 16.2). 90 (35%) patients suffered from sport-related concussions (SRC). Daily post-traumatic headache patients had higher Sport Concussion Assessment Tool (SCAT)-3 symptom severity scores than the non-daily post-traumatic headache and the headache-free patients (50.2 [SD 28.2] vs. 33.1 [SD 27.5] vs. 21.6 SD23], p < 0.001). Patients with SRC had lower headache intensity (4.47 [SD 2.5] vs. 6.24 [SD 2.28], p < 0.001) and SCAT symptom severity scores (33.9 [SD 27.4] vs. 51.4 [SD 27.7], p < 0.001) than the other patients, but there were no differences in post-traumatic headache prevalence, frequency, and Standardized Assessment of Concussion (SAC) scores. The presence and frequency of post-traumatic headache are associated with the SCAT-3 symptom severity score, which is the most important predictor for post-concussion recovery. The SCAT-3 symptom severity score might be a useful tool to help characterize patients' post-traumatic headache.

2016-09-01

After identifying the most seizure-relevant characteristics by a previously developed heuristic classifier, a data-driven post-processor using a novel set of features is applied to improve the performance. The main characteristics of the outputs of the heuristic algorithm are extracted by five sets of features including synchronization, evolution, retention, segment, and signal features. Then, a support vector machine and a decision making layer remove the falsely detected segments. Four datasets including 71 neonates (1023h, 3493 seizures) recorded in two different university hospitals, are used to train and test the algorithm without removing the dubious seizures. The heuristic method resulted in a false alarm rate of 3.81 per hour and good detection rate of 88% on the entire test databases. The post-processor, effectively reduces the false alarm rate by 34% while the good detection rate decreases by 2%. This post-processing technique improves the performance of the heuristic algorithm. The structure of this post-processor is generic, improves our understanding of the core visually determined EEG features of neonatal seizures and is applicable for other neonatal seizure detectors. The post-processor significantly decreases the false alarm rate at the expense of a small reduction of the good detection rate. Copyright © 2016 International Federation of Clinical Neurophysiology.

The majority of individuals with post-traumatic headache have symptoms that are indistinguishable from migraine. The overlap in symptoms amongst these individuals raises the question as to whether post-traumatic headache has a unique pathophysiology or if head trauma triggers migraine. The objective of this study was to compare brain structure in individuals with persistent post-traumatic headache (i.e. headache lasting at least 3 months following a traumatic brain injury) attributed to mild traumatic brain injury to that of individuals with migraine. Twenty-eight individuals with persistent post-traumatic headache attributed to mild traumatic brain injury and 28 individuals with migraine underwent brain magnetic resonance imaging on a 3 T scanner. Regional volumes, cortical thickness, surface area and curvature measurements were calculated from T1-weighted sequences and compared between subject groups using ANCOVA. MRI data from 28 healthy control subjects were used to interpret the differences in brain structure between migraine and persistent post-traumatic headache. Differences in regional volumes, cortical thickness, surface area and brain curvature were identified when comparing the group of individuals with persistent post-traumatic headache to the group with migraine. Structure was different between groups for regions within the right lateral orbitofrontal lobe, left caudal middle frontal lobe, left superior frontal lobe, left precuneus and right supramarginal gyrus (p < .05). Considering these regions only, there were differences between individuals with persistent post-traumatic headache and healthy controls within the right lateral orbitofrontal lobe, right supramarginal gyrus, and left superior frontal lobe and no differences when comparing the migraine cohort to healthy controls. In conclusion, persistent post-traumatic headache and migraine are associated with differences in brain structure, perhaps suggesting differences in their underlying

Post traumatic inferior vena cava (IVC) thrombosis is a rare and not well described entity with nonspecific clinical presentation. It remains a therapeutic challenge in traumatic context because of haemorrhagic risk due to anticoagulation. We report a case of IVC thrombosis in an 18 year-old man who presented with liver injury following a traffic crash. The thrombosis was incidentally diagnosed on admission by computed tomography. The patient was managed conservatively without anticoagulation initially considering the increasing haemorrhagic risk. IVC filter placing was not possible because of the unusual localization of the thrombus. Unfractionated heparin was started on the third day after CT scan control showing stability of hepatic lesions with occurrence of a pulmonary embolism. The final outcome was good. The management of post traumatic IVC thrombosis is not well described. Medical approach consists in conservative management with anticoagulation which requires the absence of active bleeding lesions. Surgical treatment is commonly based on thrombectomy under extracorporeal circulation. Interventional vascular techniques have become an important alternative approach for the treatment of many vessel lesions. Their main advantages are the relative ease and speed with which they can be performed. Post traumatic IVC thrombosis is a rare condition. Its management is not well defined. Early anticoagulation should be discussed on a case-by-case basis. Other alternatives such IVC filter or surgical thrombectomy may be used when the bleeding risk is increased. The most serious risk is pulmonary embolism. Outcome can be favorable even with non surgical approaches. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

Few efficacious early treatments for post-traumatic stress disorder (PTSD) in children and adolescents exist. Previous trials have intervened within the first month post-trauma and focused on secondary prevention of later post-traumatic stress; however, considerable natural recovery may still occur up to 6-months post-trauma. No trials have addressed the early treatment of established PTSD (i.e. 2- to 6-months post-trauma). Twenty-nine youth (8-17 years) with PTSD (according to age-appropriate DSM-IV or ICD-10 diagnostic criteria) after a single-event trauma in the previous 2-6 months were randomly allocated to Cognitive Therapy for PTSD (CT-PTSD; n = 14) or waiting list (WL; n = 15) for 10 weeks. Significantly more participants were free of PTSD after CT-PTSD (71%) than WL (27%) at posttreatment (intent-to-treat, 95% CI for difference .04-.71). CT-PTSD yielded greater improvement on child-report questionnaire measures of PTSD, depression and anxiety; clinician-rated functioning; and parent-reported outcomes. Recovery after CT-PTSD was maintained at 6- and 12-month posttreatment. Beneficial effects of CT-PTSD were mediated through changes in appraisals and safety-seeking behaviours, as predicted by cognitive models of PTSD. CT-PTSD was considered acceptable on the basis of low dropout and high treatment credibility and therapist alliance ratings. This trial provides preliminary support for the efficacy and acceptability of CT-PTSD as an early treatment for PTSD in youth. Moreover, the trial did not support the extension of 'watchful waiting' into the 2- to 6-month post-trauma window, as significant improvements in the WL arm (particularly in terms of functioning and depression) were not observed. Replication in larger samples is needed, but attention to recruitment issues will be required. © 2016 The Authors.

In a randomised controlled study, a type of cognitive behavior therapy known as Rational Rehabilitation proved effective in the treatment of patients with chronic mental symptoms. Post-traumatic stress disorder is a serious illness that occurs frequently and can last for many years. Rational Rehabilitation may also be an effective treatment for post-traumatic stress disorder. To investigate, via a pilot study, on the effect of Rational Rehabilitation in patients with post-traumatic stress disorder, whether a randomised controlled study is called for. Nineteen patients with post-traumatic stress disorder, who were awaiting regular treatment, opted to join the study. The effect of Rational Rehabilitation was studied in relation to: symptoms of post-traumatic stress disorder, degree of happiness experienced, autonomy, social support and need for further treatment. results Rational Rehabilitation seems to have a positive effect on all outcome measures, except flashbacks. A controlled study of the effect of Rational Rehabilitation in patients with post-traumatic stress disorder seems justified.

POST Traumatic Stress Disorder in Emergency Workers: Risk Factors and Treatment

NASA Astrophysics Data System (ADS)

Argentero, Piergiorgio; Dell'Olivo, Bianca; Setti, Ilaria

Post traumatic stress disorder (PTSD) are emergent phenomena resulting from exposure to a traumatic event that causes actual or threatened death or injury and produces intense fear, helplessness, or horror. In order to assess the role of different factors contributing to this kind of emergent phenomenon prevalence rates across gender, cultures, and samples exposed to different traumas are examined. Risk factors for PTSD, including pre-existing individual-based factors, features of the traumatic event, and post-trauma interventions are examined as well. Several characteristics of the trauma, related to cognitions, post-trauma social support and therapeutic interventions for PTSD are also considered. Further work is needed in order to analyze the inter-relationships among these factors and underlying mechanisms. The chaotic nature of traumatic processes, the multiple and interactive impacts on traumatic events require a comprehensive perspective aimed at planning effective interventions. Treatment outcome studies recommended the combined use of training and therapies as first-line treatment for PTSD.

This study developed a measure of physical post traumatic growth (physical post traumatic growth inventory; P-PTGI) in men with prostate cancer. A pool of items was created from themes identified in a qualitative study. A quantitative study was then conducted to assess the psychometric properties of the P-PTGI in a sample of 693 prostate cancer survivors. Tests of dimensionality revealed that the 20-item P-PTGI contained two factors: Health Autonomy and Health Awareness. Results demonstrated that scale score reliability for the P-PTGI and its subscales was excellent. In support of the scale's convergent validity, scores on the P-PTGI correlated positively with mindfulness and quality of life, and correlated negatively with depression and anxiety. A statistically significant correlation between the P-PTGI and another robust indicator of post traumatic growth attests to its concurrent validity. While further investigation of the P-PTGI's psychometric properties is required, preliminary findings are promising.

Prenatal corticosteroid exposure alters early developmental seizures and behavior

In humans, corticosteroids are often administered prenatally to improve lung development in preterm neonates. Studies in exposed children as well as in children, whose mothers experienced significant stress during pregnancy indicate behavioral problems and possible increased occurrence of epileptic spasms. This study investigated whether prenatal corticosteroid exposure alters early postnatal seizure susceptibility and behaviors. On gestational day 15, pregnant rats were injected i.p. with hydrocortisone (2× 10 mg/kg), betamethasone (2× 0.4 mg/kg) or vehicle. On postnatal day (P)15, seizures were induced by flurothyl or kainic acid (3.5 or 5.0 mg/kg). Horizontal bar holding was determined prior to seizures and again on P17. Performance in the elevated plus maze was assessed on P20-22. Prenatal exposure to betamethasone decreased postnatal susceptibility to flurothyl-induced clonic seizures but not to kainic acid-induced seizures. Prenatal hydrocortisone decreased postnatal weight but did not affect seizure susceptibility. Hydrocortisone alone did not affect performance in behavioral tests except for improving horizontal bar holding on P17. A combination of prenatal hydrocortisone and postnatal seizures resulted in increased anxiety. Prenatal exposure to mineralocorticoid receptor blocker canrenoic acid did not attenuate, but surprisingly amplified the effects of hydrocortisone on body weight and significantly worsened horizontal bar performance. Thus, prenatal exposure to excess corticosteroids alters postnatal seizure susceptibility and behaviors. Specific effects may depend on corticosteroid species. PMID:21429712

There is a well-described association between infantile epilepsy and pervasive cognitive and behavioral deficits, including a high incidence of autism spectrum disorders. Despite the robustness of the relationship between early-life seizures and the development of autism, the pathophysiological mechanism by which this occurs has not been explored. As a result of increasing evidence that autism is a disorder of brain connectivity we hypothesized that early-life seizures would interrupt normal brain connectivity during brain maturation and result in an autistic phenotype. Normal rat pups underwent recurrent flurothyl-induced seizures from postnatal (P) day 5-14 and then tested, along with controls, for developmental alterations of development brain oscillatory activity from P18-25. Specifically we wished to understand how normal changes in rhythmicity in and between brain regions change as a function of age and if this rhythmicity is altered or interrupted by early life seizures. In rat pups with early-life seizures, field recordings from dorsal and ventral hippocampus and prefrontal cortex demonstrated marked increase in coherence as well as a decrease in voltage correlation at all bandwidths compared to controls while there were minimal differences in total power and relative power spectral densities. Rats with early-life seizures had resulting impairment in the sociability and social novelty tests but demonstrated no evidence of increased activity or generalized anxiety as measured in the open field. In addition, rats with early-life seizures had lower seizure thresholds than controls, indicating long-standing alterations in the excitatory/inhibition balance. Bumetanide, a pharmacological agent that blocks the activity of NKCC1 and induces a significant shift of ECl toward more hyperpolarized values, administration at the time of the seizures precluded the subsequent abnormalities in coherence and voltage correlation and resulted in normal sociability and seizure

Increasing evidence indicates that post-traumatic stress disorder (PTSD) may develop following traumatic brain injury (TBI), despite most patients having no conscious memory of their accident. This prospective study examined the frequency, timing of onset, symptom profile, and trajectory of PTSD and its psychiatric comorbidities during the first 4 years following moderate-to-severe TBI. Participants were 85 individuals (78.8% male) with moderate or severe TBI recruited following admission to acute rehabilitation between 2005 and 2010. Using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Disorders (SCID-I), participants were evaluated for pre- and post-injury PTSD soon after injury and reassessed at 6 months, 12 months, 2 years, 3 years, and 4 years post-injury. Over the first 4 years post-injury, 17.6% developed injury-related PTSD, none of whom had PTSD prior to injury. PTSD onset peaked between 6 and 12 months post-injury. The majority of PTSD cases (66.7%) had a delayed-onset, which for a third was preceded by subsyndromal symptoms in the first 6 months post-injury. PTSD frequency increased over the first year post-injury, remained stable during the second year, and gradually declined thereafter. The majority of subjects with PTSD experienced a chronic symptom course and all developed one or more than one comorbid psychiatric disorder, with mood, other anxiety, and substance-use disorders being the most common. Despite event-related amnesia, post-traumatic stress symptoms, including vivid re-experiencing phenomena, may develop following moderate-to-severe TBI. Onset is typically delayed and symptoms may persist for several years post-injury.

Challenges in treating post-traumatic stress disorder and attachment trauma.

PubMed

Allen, Jon G

2003-06-01

Treating women suffering from trauma poses significant challenges. The diagnostic prototype of post-traumatic stress disorder (PTSD) is based on single-event trauma, such as sexual assault in adulthood. Several effective cognitive- behavioral treatments for such traumas have been developed, although many treated patients continue to experience residual symptoms. Even more problematic is the complex developmental psychopathology stemming from a lifetime history of multiple traumas, often beginning with maltreatment in early attachment relationships. A history of attachment trauma undermines the development of capacities to regulate emotional distress and thereby complicates the treatment of acute trauma in adulthood. Such complex trauma requires a multifaceted treatment approach that must balance processing of traumatic memories with strategies to contain the intense emotions this processing evokes. Moreover, conducting such treatment places therapists at risk for secondary trauma such that trauma therapists also must process this stressful experience and implement strategies to regulate their own distress.

Thoracoscopic evacuation of retained post-traumatic hemothorax.

Post-traumatic retained hemothorax is a major risk factor for empyema thoracis leading to prolonged hospitalization, entrapped lung and a need for decortication. VATS (Video Assisted Thoracoscopy) for retained hemothorax shortens the duration of chest tube drainage and length of stay. From December 2004 to July 2009, 110 consecutive patients underwent VATS for retained or clotted hemothoraces at the Department of Thoracic Surgery, Jinnah Postgraduate Medical Centre, Karachi. Majority of the patients were males (n = 91; 82.7%). Sixty-five patients (59.1%) underwent VATS within 6 days and 45 patients (40.9%) between 7 - 14 days of injury. In 8 patients (7.3%) VATS was abandoned for thoracotomy. Post VATS full lung expansion was achieved in 87 patients (79.0) with complete evacuation of hemothorax. Chest tubes were removed within the first week in 100 patients (90.9%). In hemodynamically stable patients, VATS is a safe, reliable and effective technique for the evacuation of retained hemothorax. Early intervention within 6 days of injury avoids the need for a thoracotomy and is associated with a better short and long-term outcome.

Post-traumatic tricuspid insufficiency: a case report.

2011-11-01

Post-traumatic tricuspid insufficiency is a rare complication of chest trauma. An 18-year-old male patient was injured in a bicycle accident from his abdominal and anterior chest wall. The tear on the inferior diaphragmatic surface of the heart was repaired with primary sutures by the attending surgeon. Eighteen years later, he was admitted to the hospital with severe tricuspid regurgitation (3+/4+). During the operation, the valve was determined unsuitable for repair and was replaced with a bioprosthesis. The hemodynamic aberrations relevant to an isolated tricuspid valve injury are very often well-tolerated. Reconstructive surgery may be possible in the early period. In the late cases, repair is sometimes not feasible due to degeneration of the valvular apparatus. Replacement with a biological prosthesis may give the best long-term results in longstanding cases.

Post-Traumatic Stress Disorder, Depression and Anxiety among North Korean Refugees: A Meta-Analysis.

Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), p<0.001, z=8.33, and anxiety, r=0.51, 95% CI (0.36, 0.63), p<0.001, z=6.07. The relationships between post-traumatic stress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

Memories of Vietnam: post-traumatic stress disorders in Australian veterans.

We compared a random sample of Australian Vietnam veteran inpatients suffering from Post Traumatic Stress Disorder (PTSD) (N = 13) with veteran inpatients with other neurotic diagnoses. Those with PTSD had experienced substantially higher levels of combat stress, were more likely to have manifested conduct disorder in childhood, and had poorer work adjustment. Only three had been diagnosed as having traumatic or war neuroses by their original treating psychiatrist in the Veterans Affairs Department. Post traumatic stress disorder (or war neurosis) has possibly been under-diagnosed by treating psychiatrists in the Veterans Affairs Department, especially in the pre-DSM-III era.

To assess and compare post-traumatic osteoarthritis following intra-articular calcaneal fractures, one must have a reliable grading system that consistently grades the post-traumatic changes of the joint. A reliable grading system aids in the communication between treating physicians and improves the interpretation of research. To date, there is no consensus on what grading system to use in the evaluation of post-traumatic subtalar osteoarthritis. The objective of this study was to determine and compare the inter- and intra-rater reliability of two grading systems for post-traumatic subtalar osteoarthritis. Four observers evaluated 50 calcaneal fractures at least one year after trauma on conventional oblique lateral, internally and externally rotated views, and graded post-traumatic subtalar osteoarthritis using the Kellgren and Lawrence Grading Scale (KLGS) and the Paley Grading System (PGS). Inter- and intra-rater reliability were calculated and compared. The inter-rater reliability showed an intra-class correlation (ICC) of 0.54 (95 % CI 0.40-0.67) for the KLGS and an ICC of 0.41 (95 % CI 0.26 - 0.57) for the PGS. This difference was not statistically significant. The intra-rater reliability showed a mean weighted kappa of 0.62 for both the KLGS and the PGS. There is no statistically significant difference in reliability between the Kellgren and Lawrence Grading System (KLGS) and the Paley Grading System (PGS). The PGS allows for an easy two-step approach making it easy for everyday clinical purposes. For research purposes however, the more detailed and widely used KLGS seems preferable.

The Buffalo Cardio-metabolic Occupational Police Stress study, an occupational cohort study of police officers, was conducted to evaluate physiologic and stress measures in a high-risk occupation where occupational exposure to difficult criminal situations can lead to physiologic and psychological health consequences among those who enforce the law. The chronic exposure to human tragedy may place police officers at special risk for mental health disorders and the potential for misuse of alcohol or drugs. While exact etiologies of post-traumatic stress were not determined by this study, overall post-traumatic stress (PTS) prevalence rates among the police officers was 35%, with 10% of individuals demonstrating severe PTS symptomatology. Waking cortisol measures tended to be higher among officers with more PTS symptomatology, with some gender related differences noted. Given the increase in incarcerations for addictions related offenses over the past 20 years and the chronic exposure to human suffering and tragedy, early recognition of PTS symptoms is essential in making the diagnosis of post-traumatic stress in high-risk occupational cohorts. Providing early entry into treatment and subsequently attempting to eliminate or minimize long-term consequences of post-traumatic stress can have a significant impact on the prevention of long term sequelae of chronic stress, such as the use or misuse of drugs or alcohol.

Determine the effect of traumatic event re-exposure and post-traumatic stress disorder (PTSD) symptom severity on proximal drug use and drug abuse treatment-seeking in syringe exchange participants. Prospective longitudinal 16-month cohort study of new syringe exchange registrants enrolled in a parent study of methods to improve treatment engagement. Data were collected in a research van next to mobile syringe exchange distribution sites in Baltimore, Maryland. Male and female (n = 162) injecting drug users (IDUs) registered for syringe exchange. Traumatic event re-exposure was identified each month with the Traumatic Life Events Questionnaire. PTSD symptoms were measured with the Modified PTSD Symptom Scale-Revised, given every 4 months. Outcome measures collected monthly were days of drug use (heroin, cocaine) and drug abuse treatment-seeking behavior (interest, calls to obtain treatment, treatment participation). Each traumatic event re-exposure was associated with about 1 more day of cocaine use after accounting for the previous month's cocaine use [same month adjusted B, standard error = 1.16 (0.34); 1 month later: 0.99 (0.34)], while PTSD symptoms had no effect. Traumatic event re-exposure increased interest in drug abuse treatment [same month adjusted odds ratios with 95% confidence intervals = 1.34 (1.11-1.63)] and calling to obtain treatment [same month 1.58 (1.24-2.01); 1 month later 1.34 (1.03-1.75)]. Each 10% increase in PTSD symptom severity was associated with persistent increased interest in treatment [same month 1.25 (1.10-1.42); 1 month later 1.16 (1.02-1.32); 2 months later 1.16 (1.02-1.32)] and calling to obtain treatment [same month 1.16 (1.02-1.32)]. Neither traumatic events nor PTSD symptoms were associated with participants receiving treatment. Becoming exposed again to traumatic events among injecting drug users is associated with an increase in cocaine use up to 1 month later, but drug use is not related to post-traumatic stress disorder

On 11 March 2011, a massive undersea earthquake, measuring 9.0 on the Richter scale, caused a tsunami that devastated the shoreline of east Japan. It is estimated that over 20,000 people lost their lives as a result. It is recommended that clinical effort after a tsunami disaster concentrate on a high-impact area rather than cover a large area. However, regional differences in post-traumatic stress symptoms among children after a tsunami disaster are not well clarified. This study evaluated post-traumatic stress symptoms and reported the findings of early-phase screening of 2259 students from Higashi-Matsushima City, Japan, 6 weeks after a tsunami hit the city. The sample was divided into two age groups: elementary school students (n=1102) and junior high school students (n=1157). Of these groups, 289 (26.2%) elementary school students and 123 (10.6%) junior high school students attended the four schools that were located in the area struck by the tsunami; the mortality rate of the area exceeded 4%. We referred to these students as the "high-impact group." The "lower-impact group" consisted of 813 (73.8%) elementary school students and 1034 (89.4%) junior high school students who attended the remaining ten schools. The severity of post-traumatic stress symptoms did not significantly differ between areas with relatively high and low impact. However, among the junior high school students, those attending the school in the highly impacted area showed higher post-traumatic symptoms scores than did the students of the less-impacted area. When planning a mass intervention after a disaster, especially in the early phase when the resources for intervention are not sufficient, it might be useful to consider the degree of age-dependent impact effect.

This study investigated the post traumatic stress disorder (PTSD) and post traumatic growth (PTG) in 2,300 earthquake survivors 1 year after the 2008 Wenchuan earthquake. This study aimed to investigate the relationship between PTSD and PTG and also tested for the gender differences in PTSD and PTG subgroups. A stratification random sampling strategy and questionnaires were used to collect the data. The PTSD was assessed using the PTSD Check list-Civilian and the PTG was assessed using the Post traumatic growth inventory. 2,300 individuals were involved in the initial survey with 2,080 completing the final questionnaire, a response rate of 90.4%. One-way ANOVA analyses were performed to investigate the gender differences in the PTSD and PTG subgroups. One year following the earthquake, 40.1 and 51.1% of survivors reported PTSD and PTG, respectively. A bivariate correlation analysis indicated that there was a positive association between PTG and PTSD. The PTG and PTSD variance analysis conducted on female and male subgroups suggested that women were more affected than men. Given the relatively high PTG prevalence, it was concluded that researchers need to pay more attention to the positive outcomes of an earthquake rather than just focusing on the negative effects. The surveys and analyses indicated that psychological intervention and care for the earthquake disaster survivors should focus more on females and older people, who tend to be more adversely affected.

Post-traumatic acute respiratory distress syndrome (ARDS) is associated with prolonged mechanical ventilation and longer hospitalizations. The relationship between post-traumatic ARDS severity and financial burden has not been previously studied. We hypothesized that increasing severity is associated with incrementally higher health care costs. Adults arriving as the highest level of trauma activation were enrolled in an ongoing prospective cohort study. Patients who survived ≥6 hours are included in the analysis. Blinded review of chest radiographs was performed by two independent physicians for any intubated patient with PaO2:FiO2 ratio (P/F) ≤300mgHg during the first 8 days of admission. The severity of ARDS was classified by the Berlin criteria. Hospital charge data was utilized to perform standard costing analysis. ARDS occurred in 13% (203/1586). The distribution of disease severity was 33% mild, 42% moderate, and 25% severe. Patients with ARDS were older (41 vs 35 years, p<0.01), had higher median ISS (30 vs 10, p<0.01), more chest injury (AIS≥3: 51% vs 21%, p<0.01), and blunt mechanisms (85% vs 53%, p<0.01). By ARDS severity, there was no significant difference in age, mechanism, or rate of traumatic brain injury. Increasing ARDS severity was associated with higher ISS and higher mortality rates. Standardized total hospital charges were four-fold higher for patients who developed ARDS compared to those who did not develop ARDS ($434K vs $96K, p<0.01). Furthermore, the daily hospital charges significantly increased across categories of worsening ARDS severity (mild $20,451; moderate $23,994; severe $33,316, p<0.01). The development of post-traumatic ARDS is associated with higher health care costs. Among trauma patients who develop ARDS, total hospital charges per day increase with worsening severity of disease. Prevention, early recognition, and treatment of ARDS after trauma are potentially important objectives for efforts to control health care

Low pressure hyperbaric oxygen therapy and SPECT brain imaging in the treatment of blast-induced chronic traumatic brain injury (post-concussion syndrome) and post traumatic stress disorder: a case report

PubMed Central

2009-01-01

A 25-year-old male military veteran presented with diagnoses of post concussion syndrome and post traumatic stress disorder three years after loss of consciousness from an explosion in combat. The patient underwent single photon emission computed tomography brain blood flow imaging before and after a block of thirty-nine 1.5 atmospheres absolute hyperbaric oxygen treatments. The patient experienced a permanent marked improvement in his post-concussive symptoms, physical exam findings, and brain blood flow. In addition, he experienced a complete resolution of post-traumatic stress disorder symptoms. After treatment he became and has remained employed for eight consecutive months. This case suggests a novel treatment for the combined diagnoses of blast-induced post-concussion syndrome and post-traumatic stress disorder. PMID:19829822

Rotator cuff strain: a post-traumatic mimicker of tendonitis on MRI.

To determine whether there is a subset of young patients (< 35 years) with acute, post-traumatic insults to the rotator cuff which mimic the early stages of impingement. One hundred and ninety-seven consecutive shoulder MR images were retrospectively reviewed, and the results of 83 clinically correlated. Two observers independently evaluated the location of intra-tendon signal and adjacent bone marrow abnormalities on T1- and T2-weighted images. These findings were correlated with age, history of trauma, and surgical or clinical follow-ups. Patients younger than 35 years had signal intensity that was more localized in atypical locations (posterior aspect of the supraspinatus tendon), more commonly associated with marrow abnormalities (presumed bone bruise), and more often associated with trauma. Younger patients also were less likely to require surgery, especially if they showed bone bruises. This differentiated them from older patients (> 45 years), who demonstrated more widespread signal within the tendon, rare bone bruises, and more frequent surgery. Localized tendon signal in atypical locations of the supraspinatus tendon, particularly when associated with bone bruise and young age, suggests the possibility of a post-traumatic strain.

We reviewed the existing literature on the efficacy of anticonvulsants in treating post-traumatic stress disorder. We performed a literature search using PubMed, EMBASE and the Cochrane database on 30 September 2013. Randomized,controlled studies that investigated the efficacy of anticonvulsants for post-traumatic stress disorder were included in this review. Studies with retrospective designs, case reports and case series were excluded. A total of seven studies met the inclusion criteria for this review. Three studies used topiramate with negative findings regarding its efficacy. Two studies used divalproex, both of which failed to show superiority over placebo. One study used lamotrigine, with favourable results, and one study used tiagabine, with negative results. Future long-term studies with larger sample sizes are needed to investigate the clinical utility of anticonvulsants for posttraumatic stress disorder treatment.

Post-traumatic stress disorder (PTSD) is a chronic and difficult to treat psychiatric disorder. Objective, performance-based diagnostic markers that uniquely index risk for PTSD above and beyond subjective self-report markers could inform attempts to improve prevention and early intervention. We evaluated the predictive value of threat-related attention bias measured immediately after a potentially traumatic event, as a risk marker for PTSD at a 3-month follow-up. We measured the predictive contribution of attentional threat bias above and beyond that of the more established marker of risk for PTSD, self-reported psychological dissociation. Dissociation symptoms and threat-related attention bias were measured in 577 motor vehicle accident (MVA) survivors (mean age = 35.02 years, 356 males) within 24 h of admission to an emergency department (ED) of a large urban hospital. PTSD symptoms were assessed at a 3-month follow-up using the Clinician-Administered PTSD Scale (CAPS). Self-reported dissociation symptoms significantly accounted for 16% of the variance in PTSD at follow-up, and attention bias toward threat significantly accounted for an additional 4% of the variance in PTSD. Threat-related attention bias can be reliably measured in the context of a hospital ED and significantly predicts risk for later PTSD. Possible mechanisms underlying the association between threat bias following a potentially traumatic event and risk for PTSD are discussed. The potential application of an attention bias modification treatment (ABMT) tailored to reduce risk for PTSD is suggested.

Disrupted rapid eye movement sleep predicts poor declarative memory performance in post-traumatic stress disorder.

Successful memory consolidation during sleep depends on healthy slow-wave and rapid eye movement sleep, and on successful transition across sleep stages. In post-traumatic stress disorder, sleep is disrupted and memory is impaired, but relations between these two variables in the psychiatric condition remain unexplored. We examined whether disrupted sleep, and consequent disrupted memory consolidation, is a mechanism underlying declarative memory deficits in post-traumatic stress disorder. We recruited three matched groups of participants: post-traumatic stress disorder (n = 16); trauma-exposed non-post-traumatic stress disorder (n = 15); and healthy control (n = 14). They completed memory tasks before and after 8 h of sleep. We measured sleep variables using sleep-adapted electroencephalography. Post-traumatic stress disorder-diagnosed participants experienced significantly less sleep efficiency and rapid eye movement sleep percentage, and experienced more awakenings and wake percentage in the second half of the night than did participants in the other two groups. After sleep, post-traumatic stress disorder-diagnosed participants retained significantly less information on a declarative memory task than controls. Rapid eye movement percentage, wake percentage and sleep efficiency correlated with retention of information over the night. Furthermore, lower rapid eye movement percentage predicted poorer retention in post-traumatic stress disorder-diagnosed individuals. Our results suggest that declarative memory consolidation is disrupted during sleep in post-traumatic stress disorder. These data are consistent with theories suggesting that sleep benefits memory consolidation via predictable neurobiological mechanisms, and that rapid eye movement disruption is more than a symptom of post-traumatic stress disorder. © 2014 European Sleep Research Society.

The unambiguous identification of the epileptogenic tubers in individuals with tuberous sclerosis complex (TSC) can be challenging. We assessed whether magnetic source imaging (MSI) and coregistration of (18)fluorodeoxyglucose PET (FDG-PET) with MRI could improve the identification of the epileptogenic regions noninvasively in children with TSC. In addition to standard presurgical evaluation, 28 children with intractable epilepsy from TSC referred from 2000 to 2007 had MSI and FDG-PET/MRI coregistration without extraoperative intracranial EEG. Based on the concordance of test results, 18 patients with TSC (64%) underwent surgical resection, with the final resection zone confirmed by intraoperative electrocorticography. Twelve patients are seizure free postoperatively (67%), with an average follow-up of 4.1 years. Younger age at surgery and shorter seizure duration were associated with postoperative seizure freedom. Conversely, older age and longer seizure duration were linked with continued seizures postoperatively or prevented surgery because of nonlateralizing or bilateral independent epileptogenic zones. Complete removal of presurgery MSI dipole clusters correlated with postoperative seizure freedom. Magnetic source imaging and (18)fluorodeoxyglucose PET/MRI coregistration noninvasively localized the epileptogenic zones in many children with intractable epilepsy from tuberous sclerosis complex (TSC), with 67% seizure free postoperatively. Seizure freedom after surgery correlated with younger age and shorter seizure duration. These findings support the concept that early epilepsy surgery is associated with seizure freedom in children with TSC and intractable epilepsy.

Objectives: Post-traumatic growth (PTG) and its opposite—post-traumatic depreciation (PTD)—may be treated as important indicators of the patient quality of life. In the absence of studies on both, PTG and PTD in cancer patients, we investigated (1) coping strategies and support effectiveness as predictors of PTG and PTD in post-mastectomy women, (2) homogeneous classes with different intensity of PTG and PTD symptoms, and (3) correlates of class membership. Methods: Coping strategies (Brief COPE), support effectiveness (SSE-Q), PTG (PTGI), and PTD (negatively reworded items of PTGI) were measured in 84 post-mastectomy women (mean age = 62.27, SD = 8.38). Multiple regression, two-step cluster, and multinomial logistic regression were applied. Results: PTG and PTD had unique predictors: time since diagnosis and positive emotion-focused coping predicted PTG (R2 = 0.24), while negative emotion-focused and avoidance-focused coping and low support effectiveness were linked to PTD (R2 = 0.14). Four groups of PTG × PTD symptoms were identified: high PTG low PTD group (52.4%), low PTG low PTD group (17.9%), high PTG high PTD group (15.5%), and low PTG high PTD group (14.3%). Higher emotion- and avoidance-focused coping was characteristic for the high PTD low PTG group (R2 = 0.41). Conclusion: Our findings shed light on the coexistence and unique predictors of PTG and PTD after mastectomy, indicating heterogeneity in PTG and PTD levels among post-mastectomy women.

Objectives: Post-traumatic growth (PTG) and its opposite-post-traumatic depreciation (PTD)-may be treated as important indicators of the patient quality of life. In the absence of studies on both, PTG and PTD in cancer patients, we investigated (1) coping strategies and support effectiveness as predictors of PTG and PTD in post-mastectomy women, (2) homogeneous classes with different intensity of PTG and PTD symptoms, and (3) correlates of class membership. Methods: Coping strategies (Brief COPE), support effectiveness (SSE-Q), PTG (PTGI), and PTD (negatively reworded items of PTGI) were measured in 84 post-mastectomy women (mean age = 62.27, SD = 8.38). Multiple regression, two-step cluster, and multinomial logistic regression were applied. Results: PTG and PTD had unique predictors: time since diagnosis and positive emotion-focused coping predicted PTG ( R 2 = 0.24), while negative emotion-focused and avoidance-focused coping and low support effectiveness were linked to PTD ( R 2 = 0.14). Four groups of PTG × PTD symptoms were identified: high PTG low PTD group (52.4%), low PTG low PTD group (17.9%), high PTG high PTD group (15.5%), and low PTG high PTD group (14.3%). Higher emotion- and avoidance-focused coping was characteristic for the high PTD low PTG group ( R 2 = 0.41). Conclusion: Our findings shed light on the coexistence and unique predictors of PTG and PTD after mastectomy, indicating heterogeneity in PTG and PTD levels among post-mastectomy women.

Early-life seizures alter synaptic calcium-permeable AMPA receptor function and plasticity

Calcium (Ca2+)-mediated1 signaling pathways are critical to synaptic plasticity. In adults, the NMDA glutamate receptor (NMDAR) represents a major route for activity-dependent synaptic Ca2+ entry. However, during neonatal development, when synaptic plasticity is high, many AMPA glutamate receptors (AMPARs) are also permeable to Ca2+ (CP-AMPAR) due to low GluA2 subunit expression, providing an additional route for activity- and glutamate-dependent Ca2+ influx and subsequent signaling. Therefore, altered hippocampal Ca2+ signaling may represent an age-specific pathogenic mechanism. We thus aimed to assess Ca2+ responses 48 hours after hypoxia-induced neonatal seizures (HS) in postnatal day (P)10 rats, a post-seizure time point at which we previously reported LTP attenuation. We found that Ca2+ responses were higher in brain slices from post-HS rats than in controls and this increase was CP-AMPAR-dependent. To determine whether synaptic CP-AMPAR expression was also altered post-HS, we assessed the expression of GluA2 at hippocampal synapses and the expression of long-term depression (LTD), which has been linked to the presence of synaptic GluA2. Here we report a decrease 48 hours after HS in synaptic GluA2 expression at synapses and LTD in hippocampal CA1. Given the potentially critical role of AMPAR trafficking in disease progression, we aimed to establish whether post-seizure in vivo AMPAR antagonist treatment prevented the enhanced Ca2+ responses, changes in GluA2 synaptic expression, and diminished LTD. We found that NBQX treatment prevents all three of these post-seizure consequences, further supporting a critical role for AMPARs as an age-specific therapeutic target. PMID:27521497

Levetiracetam-induced neutropenia following traumatic brain injury.

PubMed

Bunnell, Kristen; Pucci, Francesco

2015-01-01

Levetiracetam is being increasingly utilized for post-traumatic brain injury seizure prophylaxis, in part because of its more favourable adverse effect profile compared to other anti-epileptics. This report highlights an unusual, clinically significant adverse drug reaction attributed to levetiracetam use in a patient with blunt traumatic brain injury. This study describes a case of isolated neutropenia associated with levetiracetam in a 52-year-old man with traumatic brain injury. The patient developed neutropenia on day 3 of therapy with levetiracetam, with an absolute neutrophil count nadir of 200. There were no other medications that may have been implicated in the development of this haematological toxicity. Neutropenia rapidly resolved upon cessation of levetiracetam therapy. Clinicians should be aware of potentially serious adverse reactions associated with levetiracetam in patients with neurological injury.

This study investigated the incidence of posttraumatic stress disorder (PTSD) and psychiatric co-morbidity following epileptic seizure, whether alexithymia mediated the relationship between self-efficacy and psychiatric outcomes, and whether the mediational effect was moderated by the severity of PTSD from other traumas. Seventy-one (M=31, F=40) people with a diagnosis of epilepsy recruited from support groups in the United Kingdom completed the Posttraumatic Stress Diagnostic Scale, the Hospital Anxiety and Depression Scale, the Toronto Alexithymia Scale-20 and the Generalized Self-Efficacy Scale. They were compared with 71 people (M=29, F=42) without epilepsy. For people with epilepsy, 51% and 22% met the diagnostic criteria for post-epileptic seizure PTSD and for PTSD following one other traumatic life event respectively. For the control group, 24% met the diagnostic criteria for PTSD following other traumatic life events. The epilepsy group reported significantly more anxiety and depression than the control. Partial least squares (PLS) analysis showed that self-efficacy was significantly correlated with alexithymia, post-epileptic seizure PTSD and psychiatric co-morbidity. Alexithymia was also significantly correlated with post-epileptic seizure PTSD and psychiatric co-morbidity. Mediation analyses confirmed that alexithymia mediated the path between self-efficacy and post-epileptic seizure PTSD and psychiatric co-morbidity. Moderated mediation also confirmed that self-efficacy and PTSD from one other trauma moderated the effect of alexithymia on outcomes. To conclude, people can develop posttraumatic stress disorder symptoms and psychiatric co-morbidity following epileptic seizure. These psychiatric outcomes are closely linked with their belief in personal competence to deal with stressful situations and regulate their own functioning, to process rather than defend against distressing emotions, and with the degree of PTSD from other traumas. © 2013 Elsevier

Post-traumatic stress disorder (PTSD) occurs in 5-10% of the population and is twice as common in women as in men. Although trauma exposure is the precipitating event for PTSD to develop, biological and psychosocial risk factors are increasingly viewed as predictors of symptom onset, severity and chronicity. PTSD affects multiple biological systems, such as brain circuitry and neurochemistry, and cellular, immune, endocrine and metabolic function. Treatment approaches involve a combination of medications and psychotherapy, with psychotherapy overall showing greatest efficacy. Studies of PTSD pathophysiology initially focused on the psychophysiology and neurobiology of stress responses, and the acquisition and the extinction of fear memories. However, increasing emphasis is being placed on identifying factors that explain individual differences in responses to trauma and promotion of resilience, such as genetic and social factors, brain developmental processes, cumulative biological and psychological effects of early childhood and other stressful lifetime events. The field of PTSD is currently challenged by fluctuations in diagnostic criteria, which have implications for epidemiological, biological, genetic and treatment studies. However, the advent of new biological methodologies offers the possibility of large-scale approaches to heterogeneous and genetically complex brain disorders, and provides optimism that individualized approaches to diagnosis and treatment will be discovered.

Traumatic stressors and post-traumatic stress disorder symptoms in headache patients.

de Leeuw, Reny; Schmidt, John E; Carlson, Charles R

2005-01-01

The aim of this study was to assess the prevalence of significant traumatic stressors and post-traumatic stress disorder (PTSD) symptoms in a headache population. Several recent publications have emphasized the relationship between life stressors and/or daily hassles and recurrent headaches. However, little is known about the prevalence and impact of major traumatic stressors in patients with recurrent headaches. Eighty patients with either migraine or tension-type headache completed a PTSD checklist. Data were compared with those from patients with chronic masticatory muscle pain of similar intensity and duration. Almost 64% of the headache patients reported one or more major traumatic stressors. This percentage was not significantly different from that of the comparison group, and fell within the broad range reported for exposure to traumatic stressors in epidemiologic studies with nonpatient populations. One out of 6 patients in the total headache sample, and 1 out of 4 of those reporting a traumatic stressor, reported symptoms suggestive of current PTSD. The prevalence of current PTSD-like symptomatology reported by the headache patients was comparable to that of the comparison group of the present study, but higher than that reported for the general population in the available literature printed in English. Traumatic stressors most often reported were not related to direct physical trauma, but rather associated with loss or serious illness of a loved one. Exposure to traumatic events in patients with a primary diagnosis of recurrent headaches is similar to that reported for chronic masticatory muscle pain patients or nonpatient populations. However, symptoms consistent with a diagnosis of current PTSD appear to be more frequent in patients with recurrent headaches than reported in the scientific literature printed in English for nonpatient populations. Screening for PTSD symptomatology is recommended as part of the routine clinical evaluation of headache.

This study examined reported post-traumatic stress disorder symptoms in adults with poorly controlled type 2 diabetes who had no history of psychiatric diagnosis or treatment ( n = 184, M HbA1c  = 9.13%, standard deviation = 1.68). Participants reported moderate to severe intensity of post-traumatic stress disorder symptoms ( M = 19.17, SD = 17.58). Together, depressive and post-traumatic stress disorder symptoms accounted for 10-40 percent of the variance in type 2 diabetes outcomes; post-traumatic stress disorder symptoms were associated with elevated diabetes distress and more frequent exercise and self-blood glucose testing (unique R 2  ~ 3%). Post-traumatic stress disorder symptoms may be overlooked in type 2 diabetes among patients without formal psychiatric diagnoses, and warrant increased attention.

The aim of this prospective study was to examine the etiology of post-traumatic stress symptoms following childbirth within a transactional framework of stress. Participants were women (N = 1,499) from the Akershus Birth Cohort. These women were followed from pregnancy to 8 weeks postpartum. We modeled predisposing factors (e.g., fear of childbirth) and precipitating factors (subjective and objective birth experiences) as predictors of post-traumatic stress symptoms. Post-traumatic stress symptoms were measured by means of the Impact of Event Scale, objective birth experiences by means of birth journals, and subjective birth experiences by means of three questions. A structural equation model showed that subjective birth experiences had the highest association with post-traumatic stress symptoms. Moreover, they mediated the effect of predisposing factors and objective birth experiences. The results suggest that women's subjective birth experiences are the most important factor in the development of post-traumatic stress symptoms following childbirth.

A growing literature shows prominent sex effects for risk for post-traumatic stress disorder and associated medical comorbid burden. Previous research indicates that post-traumatic stress disorder is associated with reduced slow wave sleep, which may have implications for overall health, and abnormalities in rapid eye movement sleep, which have been implicated in specific post-traumatic stress disorder symptoms, but most research has been conducted in male subjects. We therefore sought to compare objective measures of sleep in male and female post-traumatic stress disorder subjects with age- and sex-matched control subjects. We used a cross-sectional, 2 × 2 design (post-traumatic stress disorder/control × female/male) involving83 medically healthy, non-medicated adults aged 19-39 years in the inpatient sleep laboratory. Visual electroencephalographic analysis demonstrated that post-traumatic stress disorder was associated with lower slow wave sleep duration (F(3,82)  = 7.63, P = 0.007) and slow wave sleep percentage (F(3,82)  = 6.11, P = 0.016). There was also a group × sex interaction effect for rapid eye movement sleep duration (F(3,82)  = 4.08, P = 0.047) and rapid eye movement sleep percentage (F(3,82)  = 4.30, P = 0.041), explained by greater rapid eye movement sleep in post-traumatic stress disorder females compared to control females, a difference not seen in male subjects. Quantitative electroencephalography analysis demonstrated that post-traumatic stress disorder was associated with lower energy in the delta spectrum (F(3,82)  = 6.79, P = 0.011) in non-rapid eye movement sleep. Slow wave sleep and delta findings were more pronounced in males. Removal of post-traumatic stress disorder subjects with comorbid major depressive disorder, who had greater post-traumatic stress disorder severity, strengthened delta effects but reduced rapid eye movement effects to non-significance. These findings support previous evidence that post-traumatic

Post-traumatic stress disorder is highly prevalent among individuals who suffer from opioid use disorder. Compared to individuals with opioid use disorder alone, those with post-traumatic stress disorder have a worse course of illness, occupational functioning, and physical health. The neurobiological pathways underlying each disorder overlap substantially, and there are multiple pathways through which these disorders may interact. This narrative review explores evidence underpinning 3 explanatory perspectives on comorbid post-traumatic stress disorder and opioid use disorder: The opioid susceptibility model (a.k.a.: the Self-Medication Hypothesis), the post-traumatic stress disorder susceptibility model, and the common factors model. Diagnostic implications, treatment implications, and directions for future research are discussed.

Determining the labor factors associated with post-traumatic stress in uniformed workers in Medellin. A cross-sectional study was made of 124 uniformed workers aged 20 to 48 years-old. A survey was made using an adults' post-traumatic stress instrument which had been validated in Medellin. Statistical analysis was carried out. Post-traumatic stress disorder risk prevalence was 52.2 %. Multivariate analysis showed that the highest risk situations were those related to previous mental health diagnosis (PR=7.67), working schedule (4.24), violent episodes (PR=3.59) and community relationships (PR=2.73). A person's current labor situation seemed to be a risk factor for developing post-traumatic stress in the target population.

Early detection of epilepsy seizures based on a weightless neural network.

This work introduces a new methodology for the early detection of epileptic seizure based on the WiSARD weightless neural network model and a new approach in terms of preprocessing the electroencephalogram (EEG) data. WiSARD has, among other advantages, the capacity of perform the training phase in a very fast way. This speed in training is due to the fact that WiSARD's neurons work like Random Access Memories (RAM) addressed by input patterns. Promising results were obtained in the anticipation of seizure onsets in four representative patients from the European Database on Epilepsy (EPILEPSIAE). The proposed seizure early detection WNN architecture was explored by varying the detection anticipation (δ) in the 2 to 30 seconds interval, and by adopting 2 and 3 seconds as the width of the Sliding Observation Window (SOW) input. While in the most challenging patient (A) one obtained accuracies from 99.57% (δ=2s; SOW=3s) to 72.56% (δ=30s; SOW=2s), patient D seizures could be detected in the 99.77% (δ=2s; SOW=2s) to 99.93% (δ=30s; SOW=3s) accuracy interval.

There is limited evidence for effective interventions in the treatment of post-traumatic stress symptoms within individuals diagnosed with schizophrenia. Clinicians have concerns about using exposure treatments with this patient group. The current trial was designed to evaluate a 16-session cognitive restructuring programme, without direct exposure, for the treatment of post-traumatic stress symptoms specifically within individuals diagnosed with schizophrenia. A multicentre randomized controlled single-blinded trial with assessments at 0 months, 6 months (post-treatment) and 12 months (follow-up) was conducted. A total of 61 participants diagnosed with schizophrenia and exhibiting post-traumatic stress symptoms were recruited. Those randomized to treatment were offered up to 16 sessions of cognitive-behaviour therapy (CBT, including psychoeducation, breathing training and cognitive restructuring) over a 6-month period, with the control group offered routine clinical services. The main outcome was blind rating of post-traumatic stress symptoms using the Clinician Administered PTSD Scale for Schizophrenia. Secondary outcomes were psychotic symptoms as measured by the Positive and Negative Symptom Scale and the Psychotic Symptom Rating Scale. Both the treatment and control groups experienced a significant decrease in post-traumatic stress symptoms over time but there was no effect of the addition of CBT on either the primary or secondary outcomes. The current trial did not demonstrate any effect in favour of CBT. Cognitive restructuring programmes may require further adaptation to promote emotional processing of traumatic memories within people diagnosed with a psychotic disorder.

This case report describes a patient who presented with myelopathy secondary to a large retro-odontoid post traumatic cicatrix. The objective of this study was to discuss the clinical presentation, pathogenesis, imaging, and surgical management of pseudoarthrosis tissue mass associated with odontoid nonunion. Atlantoaxial subluxation (AAS) has been widely reported in patients with rheumatoid arthritis. AAS leads to repeated cycles of partial tear and repair of ligaments around the altantoaxial complex, resulting in the formation of periodontoid mass (pseudotumor). It is thought that formation of retro-odontoid post traumatic mass (cicatrix), in certain cases of odontoid fracture, is because of similar pathology. This is a retrospective review of case note. Here, the patient underwent posterior decompression through a C1-C2 laminectomy and occipitocervical (C0-C4) fusion with instrumentation, which resulted in dramatic improvement in his symptoms and spontaneous regression of retro-odontoid post traumatic cicatrix. We have described an interesting and a rare case of a large pseudoarthrosis tissue mass associated with odontoid nonunion, which regressed following stand-alone posterior instrumentation. To the best of our knowledge, only a handful of such cases of spontaneous regression of retro-odontoid post traumatic cicatrix following occipitocervical fixation have been described in literature, and our case adds to the growing list of such cases and may help in understanding the natural history of the disease process one day. Although rare, post traumatic cicatrix should be considered as a differential diagnosis of enhancing retro-odontoid mass, especially if there is any history of cervical spine trauma.

The aim of this prospective study was to establish the degree to which parents report post-traumatic growth after the intensive care treatment of their child. Prospective cross-sectional cohort study. Paediatric Intensive Care Unit (PICU). A total of 50 parents of children, admitted to PICU for >12 h. Parents provided stress ratings as their child was discharged from PICU and, 4 months later, completed postal questionnaires rating their anxiety, depression, post-traumatic stress and post-traumatic growth. As much as 44 parents (88%) indicated on the Posttraumatic Growth Inventory (PTGI) [1] that they had experienced a positive change to a great degree as a result of their experiences in PICU. Parents of children who were ventilated (P = 0.024) reported statistically higher post-traumatic growth as did parents of older children (P = 0.032). PTGI scores were positively correlated with post-traumatic stress scores at 4 months (P = 0.021), but on closer inspection this relationship was found to be curvilinear. Post-traumatic growth emerged as a salient concept for this population. It was more strongly associated with moderate levels of post-traumatic stress, than high or low levels.

Objective Penetrating brain injury (PBI) has the highest risk for inducing post-traumatic epilepsy and retained foreign materials such as bullet fragments carry the greatest risk. This study examines the potential contribution of copper, a major component of bullets, to the development of epilepsy following PBI. Methods Anesthetized adult male rats received a penetrating injury from the dorsal cortex to the ventral hippocampus from a high speed small bit drill. In one group of animals, copper wire was inserted into the lesion. Control animals had only the lesion or the lesion plus stainless steel wire (biologically inert foreign body). From 6 to up to 11 months following the injury the rats were monitored intermittently for the development of epilepsy with video-EEG. A separate set of animals was examined for possible acute seizures in the week following the injury. Results 22 of the 23 animals with copper wire developed chronic epilepsy compared to 3 of the 20 control rats (lesion and lesion with stainless steel). Copper was associated with more extensive injury. The control rats with epilepsy had larger lesions. In the acute injury group, there was no difference in the incidence of seizures (83% lesion plus stainless steel, 70% lesion plus copper). Conclusions Copper increases the risk for epilepsy and may increase damage over time, but there were no differences between the groups in the incidence of acute post-injury seizures. Lesion size may contribute to epilepsy development in lesion only animals. Copper maybe an independent risk factor for the development of epilepsy and possible secondary injury, but lesion size also contributes to the development of epilepsy. The consequences of prolonged exposure of the brain to copper observed in these animals may have clinical implications that require further evaluation. PMID:25470332

Qualitative interviews with 10 adolescents, mean age at assessment 17.09 years (SD 1.81). Mean time since injury 4.62 years (SD 2.89). Data were analysed using a primarily interpretative phenomenological analysis approach. Two major findings: (1) perceived quality of life was not automatically impacted by a traumatic brain injury, but when it was, the directionality of impact (positive, negative) varied depending on the life-domain; (2) changes in ability post-traumatic brain injury were attributed to the injury (more often cognitive and physical changes) or to a sense of normal maturation processes (72% and 28%, respectively). Attribution processing permeated themes of personal and social discrepancies, which also yielded themes of: altered family and relationships, roles, responsibilities, independence, coping and post-traumatic growth. All participants reported a happy life at the time of interview. The adolescents' appraisal of their identity from pre- to post-injury life was related to their current sense of well-being. Most notably was the sense of balance; participants addressed the negative and positive consequences of brain injury to qualify their sense of wellbeing.

Posttraumatic seizure (PTS) is a significant complication of traumatic brain injury (TBI). To perform a systematic review and meta-analysis to compare levetiracetam with phenytoin for seizure prophylaxis in patients diagnosed with severe TBI. An inclusive search of several electronic databases and bibliographies was conducted to identify scientific studies that compared the effect of levetiracetam and phenytoin on PTS. Independent reviewers obtained data and classified the quality of each article that met inclusion criteria. A random effects meta-analysis was then completed. During June and July 2015, a systematic literature search was performed that identified 6097 articles. Of these, 7 met inclusion criteria. A random-effects meta-analysis was performed. A total of 1186 patients were included. The rate of seizure was 35 of 654 (5.4%) in the levetiracetam cohort and 18 of 532 (3.4%) in the phenytoin cohort. Our meta-analysis revealed no change in the rate of early PTS with levetiracetam compared with phenytoin (relative risk, 1.02; 95% confidence interval, 0.53-1.95; P = .96). The lack of evidence on which antiepileptic drug to use in PTS is surprising given the number of patients prescribed an antiepileptic drug therapy for TBI. On the basis of currently available Level III evidence, patients treated with either levetiracetam or phenytoin have similar incidences of early seizures after TBI.

Dissociative seizures: a challenge for neurologists and psychotherapists.

2013-04-01

The prevalence of dissociative seizures is between 2 and 33 sufferers per 100,000 persons. 70% of sufferers are women. Dissociative seizures markedly impair quality of life. Their close superficial resemblance to epileptic seizures makes them hard to diagnose. Selective literature search in PubMed and PsycINFO. Persons with dissociative seizures constitute a mixed group with a wide variety of predisposing, precipitating, and maintaining factors. Some 90% have comorbid psychiatric disorders such as depression, anxiety, somatoform disorders, personality disorders, or post-traumatic stress disorder. Video-EEG monitoring enables highly reliable diagnosis. Psychotherapy is considered the treatment of first choice; in prospective studies, it has been found to lower the frequency of dissociative seizures by at least 50%, or to eliminate them completely, in 50% to 80% of patients. An individually tailored combination of behavioral therapeutic, imagery-based, and psychodynamic approaches seems reasonable. For the treatment of psychiatric comorbidities, psychotherapy is indicated, in combination with psychoactive drugs if necessary. Before any treatment is provided, the diagnosis should be communicated to the patient in an appropriate way, ideally by both the neurologist and the psychotherapist, so that the patient can develop an alternative disease model. When the diagnosis of dissociative seizures has been made, psychotherapy is indicated, possibly in combination with psychoactive medication, in the setting of long-term treatment provided in collaboration by the neurologist, psychiatrist, psychotherapist, and family physician. Further randomized trials are needed to determine which treatments are best for which subgroups of patients.

Post-traumatic stress disorder has been detected in patients after treatment in intensive care unit. The main goal of this study is to review the psychological aspects and therapeutic interventions on those patients after their treatment on intensive care unit. Thirty eight articles have been included. The prevalence of post-traumatic stress disorder has varied from 17% up to 30% and the incidence from 14% to 24%. The risk factors were: previous anxiety historic, depression or panic, having delusional traumatic memories (derived from psychic formations as dreams and delirium), belief effects, depressive behavior, stressing experiences and mechanical ventilation. High doses of opiates, symptoms caused by sedation or analgesia reduction and the use of lorazepam were related with the increase of delirium and delusional memory. The disorder sintomatology can be reduced with hydrocortisone administration, with daily sedation interruption. No other effectiveness psychological intervention study was found.

To investigate the relationship between traumatic brain injury (TBI) and psychogenic nonepileptic seizures (PNES). We hypothesized that PNES with TBI would be associated with more psychiatric comorbidities and disability than PNES without TBI. In this cross-sectional study comparing patients with PNES with TBI to patients with PNES without TBI, medical records from 255 consecutive patients with electroencephalography (EEG)-confirmed PNES were reviewed to assess variables including demographic, head injury, neurologic, psychiatry, social variables, and quality of life and symptoms scales. Parametric, analysis of covariance (ANCOVA), and logistic regression analyses were performed, to compare psychiatric and function variables between the two study groups while controlling for age and sex.   Of the 92 patients with PNES who fulfilled inclusion/exclusion criteria, 41 (44.6%) had a history of TBI. Of the 41 patients with TBI, 30 (73%) met criteria for mild TBI (mTBI). Patients with TBI had more mood disorder diagnoses, were more likely to receive disability, and had lower global functioning than non-TBI patients with PNES, after adjusting for age and sex. Patients with TBI and PNES had significantly increased odds for having major depression, behavioral impulsivity, posttraumatic stress disorder diagnosis, and a trauma/abuse history. TBI is a significant risk factor in patients with PNES, being associated with increased psychiatric diagnostic comorbidity, symptoms severity, poorer functioning, and increased disability. This study reveals the importance of identifying and addressing the impact of TBI in patients with seizure disorders. Addressing the sequelae of TBI in PNES may be a target to improve functioning.

The causes of post-traumatic acute kidney injury (AKI) are multifactorial, and shock associated with major trauma has been proposed to result in inadequate renal perfusion and subsequent AKI in trauma patients. This study aimed to investigate the true incidence and clinical presentation of post-traumatic AKI in hospitalized adult patients and its association with shock at a Level I trauma center. Detailed data of 78 trauma patients with AKI and 14,504 patients without AKI between January 1, 2009 and December 31, 2014 were retrieved from the Trauma Registry System. Patients with direct renal trauma were excluded from this study. Two-sided Fisher's exact or Pearson's chi-square tests were used to compare categorical data, unpaired Student's t-test was used to analyze normally distributed continuous data, and Mann-Whitney's U test was used to compare non-normally distributed data. Propensity score matching with a 1:1 ratio with logistic regression was used to evaluate the effect of shock on AKI. Patients with AKI presented with significantly older age, higher incidence rates of pre-existing comorbidities, higher odds of associated injures (subdural hematoma, intracerebral hematoma, intra-abdominal injury, and hepatic injury), and higher injury severity than patients without AKI. In addition, patients with AKI had a longer hospital stay (18.3 days vs. 9.8 days, respectively; P < 0.001) and intensive care unit (ICU) stay (18.8 days vs. 8.6 days, respectively; P < 0. 001), higher proportion of admission into the ICU (57.7% vs. 19.0%, respectively; P < 0.001), and a higher odds ratio (OR) of short-term mortality (OR 39.0; 95% confidence interval, 24.59-61.82; P < 0.001). However, logistic regression analysis of well-matched pairs after propensity score matching did not show a significant influence of shock on the occurrence of AKI. We believe that early and aggressive resuscitation, to avoid prolonged untreated shock, may help to prevent the occurrence

Sudden unexplained/unexpected death (SUDEP) is related to high mortality in patients with epilepsy. The prolongation of QT interval, involved in cardiac arrhythmia-related SUDEP, may be precipitated by antiepileptic drugs (AEDs). In this study, we evaluated the effects of phenobarbital and levetiracetam on PR-QTc intervals in patients with post-stroke seizures. We performed an open-label, parallel group, prospective, multicenter study between June 2009 and December 2013 in patients older than 18 years of age with a clinical diagnosis of post-stroke seizure and treated with phenobarbital or levetiracetam. In order to exclude a role of cerebral post-stroke injury on modulation of PR and QTc intervals, patients with cerebral post-stroke injury and without seizures were also enrolled as controls. Interictal electrocardiography analysis revealed no significant difference in PR interval between patients treated with an AED (n = 49) and control patients (n = 50) (181.25 ± 12.05 vs. 182.4 ± 10.3 ms; p > 0.05). In contrast, a significantly longer QTc interval was recorded in patients treated with an AED compared with control patients (441.2 ± 56.6 vs. 396.8 ± 49.3 ms; p < 0.01). Patients treated with phenobarbital showed a significantly longer QTc interval than patients treated with levetiracetam (460.0 ± 57.2 vs. 421.5 ± 50.1 ms; p < 0.05). The study reported that in patients with late post-stroke seizures, phenobarbital prolonged QTc interval more so than levetiracetam.

Early pediatric antiepileptic drug nonadherence is related to lower long-term seizure freedom.

To examine the relationship between previously identified nonadherence trajectories during the first 6 months of antiepileptic drug (AED) therapy and long-term seizure-free rates (defined as ≥1 year of seizure freedom at the 4 years postdiagnosis milestone) in a cohort of children with newly diagnosed epilepsy. A prospective longitudinal observational study of AED adherence and seizure freedom in a consecutive cohort of 124 children (ages 2-12 years) with newly diagnosed epilepsy was conducted. The association between previously identified AED adherence trajectories (i.e., near-perfect adherence [e.g., average adherence = 96.8%] vs nonadherent) and seizure freedom for ≥1 year at the 4 years postdiagnosis milestone was determined. Children who exhibited nonadherence to AED therapy in the first 6 months of treatment were 3.24 times more likely not to have achieved ≥1 year of seizure freedom at the 4 years postdiagnosis milestone compared to children in the near-perfect adherence group (χ² = 5.13; p = 0.02). Specifically, at the 4 years postdiagnosis milestone, only 12% of children in the near-perfect adherence group were continuing to experience seizures compared to 31% of children in the nonadherent group. Children with epilepsy who achieved near-perfect adherence during the first 6 months of therapy experienced a higher rate of seizure freedom 4 years postdiagnosis compared with those children who demonstrated early nonadherence. This suggests that adherence intervention early in the course of treatment could play a role in improving long-term seizure freedom rates in children with epilepsy.

The course of post-traumatic stress disorder after the Oklahoma City bombing.

North, C S

Oklahoma City bombing survivors (N = 182) were studied 6 months post-bombing and reassessed approximately 1 year later (N = 141) to determine the longitudinal course of post-traumatic stress disorder (PTSD) and other psychiatric disorders. The Diagnostic Interview Schedule assessed lifetime, current, predisaster, and post-bombing psychiatric diagnoses at both assessment points. One-third of the Oklahoma City bombing survivors had PTSD at index, and similar rates were diagnosed at follow-up. More recovery from depression was apparent than from PTSD. No delayed onset PTSD was observed, and all PTSD was chronic. Avoidance and numbing symptoms were dominant in defining the development of PTSD. Early onset and chronicity of PTSD indicate need for prompt and long-term intervention after disasters. Focus on avoidance and numbing symptoms may aid in identification of individuals needing intervention and monitoring the course of PTSD.

What differentiates those who are able to adapt well to adverse life events (i.e., persons who are resilient) from those who are not (e.g., persons who develop post-traumatic stress symptoms)? Previous work suggests that enhanced autobiographical integration of trauma memories is associated with more severe post-traumatic stress symptoms. Extending this line of work, the present study looked at whether the integration of trauma memories, repressive coping and cognitive reactivity are related to post-traumatic stress symptomatology following negative life events among otherwise healthy young adults (N = 213). Results show that while enhanced integration of trauma memories and high levels of dissociation are related to elevated levels of post-traumatic stress, people who generally engage in repressive coping report fewer post-traumatic stress symptoms.

Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs) of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen) Co., LTD, Guangdong, China) utilizing standard techniques. Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.

Women at pre partum and post partum are especially susceptible to war trauma because they struggle to protect their infants from danger. Trauma research suggests increased problems in maternal mental health and infant development. Yet many cognitive-emotional processes affect the trauma survivors' mental health, such as post-traumatic growth and post-traumatic cognition. The aim of this study was to examine whether a mother's high post-traumatic growth and optimal post-traumatic cognition could protect their own mental health and their infant's stress regulation from the effects of traumatic war experiences. This three-wave prospective study involved Palestinian women living in the Gaza Strip who were at the second trimester of pregnancy (T1), women with infants aged 4 months (T2), and women with children aged 12 months (T3) months. The participants reported their war experiences in a 30-item checklist of losses, destruction, and atrocities in the 2008-09, 2012, and 2014 military offensives. Post-traumatic growth was assessed by a 21-item scale and post-traumatic cognition by a 36-item scale. Maternal mental health was assessed by post-traumatic stress disorder (PTSD), depressive, anxiety, and dissociation symptoms at T1 and T3, and infants' stress regulation was assessed with the Infant Behaviour Questionnaire at T2 and T3. We included 511 women at T1, 481 women at T2, and 454 women at T3. High maternal post-traumatic growth and post-traumatic cognition had protective roles. Post-traumatic growth had a protective effect on maternal mental health since severe exposure to traumatic war experiences was not associated with maternal PTSD, depression, and dissociation if women showed high post-traumatic growth, as indicated by the significant interaction effect between post-traumatic growth and war trauma on each of the three symptoms. Post-traumatic cognition had a protective effect on infant development since severe exposure was not associated with dysfunctional

Symptoms of post-traumatic stress disorder (PTSD) and depression are highly co-morbid following a traumatic event. Nevertheless, decisive evidence regarding the direction of the relationship between these clinical entities is missing. The aim of the present study was to examine the nature of this relationship by comparing a synchronous change model (PTSD and depression are time synchronous, possibly stemming from a third common factor) with a demoralization model (i.e. PTSD symptoms causing depression) and a depressogenic model (i.e. depressive symptoms causing PTSD symptoms). Israeli adult victims of single-event traumas (n=156) were assessed on measures of PTSD and depression at 2, 4 and 12 weeks post-event. A cross-lagged structural equation modeling (SEM) analysis provided results consistent with the synchronous change model and the depressogenic model. Depressive symptoms may play an important role in the development of post-traumatic symptoms.

Exposure to workplace bullying and post-traumatic stress disorder symptomology: the role of protective psychological resources.

PubMed

Spence Laschinger, Heather K; Nosko, Amanda

2015-03-01

To examine the relationship between nurses' exposure to workplace bullying and Post-Traumatic Stress Disorder symptomology and the protective role of psychological capital (PsyCap). Workplace bullying has serious organisational and health effects in nursing. Few studies have examined the relation of workplace bullying to serious mental health outcomes, such as Post-Traumatic Stress Disorder. Even fewer have examined the effect of intrapersonal strengths on the health impact of workplace bullying. A survey of 1205 hospital nurses was conducted to test the hypothesized model. Nurses completed standardized measures of bullying, Post-Traumatic Stress Disorder and PsyCap. A moderated regression analysis revealed that more frequent exposure to workplace bullying was significantly related to Post-Traumatic Stress Disorder symptomology regardless of the PsyCap level. That is, PsyCap did not moderate the bullying/PTSD relationship in either group. Bullying exposure and PsyCap were significant independent predictors of Post-Traumatic Stress Disorder symptoms in both groups. Efficacy, a subdimension of PsyCap, moderated the bullying/Post-Traumatic Stress Disorder relationship only among experienced nurses. Workplace bullying appears to be predictive of Post-Traumatic Stress Disorder symptomology, a serious mental health outcome. Workplace bullying is a serious threat to nurses' health and calls for programmes that eliminate bullying and encourage greater levels of positive resources among nurses. © 2013 John Wiley & Sons Ltd.

Early posttraumatic seizures may contribute to worsened outcomes after traumatic brain injury. Evidence to guide the evaluation and management of early posttraumatic seizures in children is limited. We undertook a survey of current practices of continuous electroencephalographic monitoring, seizure prophylaxis, and the management of early posttraumatic seizures to provide essential information for trial design and the development of posttraumatic seizure management pathways. Surveys were sent to site principal investigators at all 43 sites participating in the Approaches and Decisions in Acute Pediatric TBI trial at the time of the survey. Surveys consisted of 12 questions addressing strategies to 1) implement continuous electroencephalographic monitoring, 2) posttraumatic seizure prophylaxis, 3) treat acute posttraumatic seizures, 4) treat status epilepticus and refractory status epilepticus, and 5) monitor antiseizure drug levels. Institutions comprised a mixture of free-standing children's hospitals and university medical centers across the United States and Europe. Site principal investigators of the Approaches and Decisions in Acute Pediatric TBI trial. None. Continuous electroencephalographic monitoring was available in the PICU in the overwhelming majority of clinical sites (98%); however, the plans to operationalize such monitoring for children varied considerably. A similar majority of sites report that administration of prophylactic antiseizure medications is anticipated in children (93%); yet, a minority reports that a specified protocol for treatment of posttraumatic seizures is in place (43%). Reported medication choices varied substantially between sites, but the majority of sites reported pentobarbital for refractory status epilepticus (81%). The presence of treatment protocols for seizure prophylaxis, early posttraumatic seizures, posttraumatic status epilepticus, and refractory status epilepticus was associated with decreased reported medications

Early malnutrition in life has permanent consequences on brain development and has been suggested to influence seizure susceptibility. Despite malnutrition is not a direct cause of seizures, we hypothesize that malnutrition may modulate inflammatory response and result in cerebral vulnerability to seizures. In this study, we provide evidence that malnutrition may increase susceptibility to seizures in the postnatal period by interleukin-1β (IL-1β) in the hippocampus. Malnourished rats were maintained on a nutritional deprivation regimen from postnatal day 1 (P1) to P10. From P7 to P10, the threshold to seizures induced by flurothyl was used as an index of seizure susceptibility. ELISA and western blot was performed to evaluate levels of IL-1β, IL-1R1, PSD-95 and synapsin. The role of inflammation in the changes of seizure threshold was studied with inhibitors of IL-1β and IL-1R1. A significant decrease in body weight and seizure threshold was observed in postnatal malnourished rats. Early malnutrition modulates inflammation by high levels of IL-1β in hippocampus and in serum. Furthermore, our malnutrition paradigm induced an increase in corticosterone levels. Injection of IL-1β and IL-1R1 inhibitors before seizure induction augments seizure threshold in malnourished rats similar to nourished group. Malnutrition did not change PSD-95 and synapsin expression in the hippocampus. We suggest that malnutrition-induced inflammation might contribute to seizure susceptibility in the postnatal period. © 2016 Wiley Periodicals, Inc.

Childbirth for some women can be experienced as a traumatic event whereby it is appraised as threatening to life and associated with feelings of fear, helplessness or horror. These women may develop symptoms consistent with post-traumatic stress disorder or its sub-clinical symptoms (post-traumatic stress, PTS). Cognitive processes such as attentional biases have been identified in individuals with PTS exposed to other traumatic events. This study used an experimental design (the modified Stroop task) to investigate the relationship between attentional biases and PTS symptoms in 50 women who experienced their labour and delivery as stressful and responded with fear, helplessness and horror. Attentional biases away from childbirth words were significantly associated with both symptoms of post-traumatic stress and more negative experiences of childbirth. A negative experience was also associated with more severe symptoms of PTS. Positive experiences were unassociated with attentional biases or symptoms. Post-traumatic stress responses, in this population, may be associated with avoidance, and through influencing cognitive processing, acting as a maintaining factor of distress.

Depression and post-traumatic stress disorder frequently occur as a consequence of occupational accidents. To date, research has been primarily focused on high-risk workers, such as police officers or firefighters, and has rarely considered individuals whose occupational environment involves the risk of severe, but not necessarily life-threatening, injury. Therefore, the present study was aimed at assessing the psychological consequences of accidents occurring in several occupational settings (e.g., construction and industry). Thirty-eight victims of occupational accidents (injured workers) and 38 gender-, age-, and years of education-matched workers who never experienced a work accident (control group) were recruited. All participants underwent a semi-structured interview administered by a trained psychologist, and then were requested to fill in the questionnaires. Injured workers reported more severe anxious, post-traumatic and depressive symptoms, and poorer coping skills, as compared to controls. In the injured group low levels of resilience predicted post-traumatic symptomatology, whereas the degree of physical injury and the length of time since the accident did not play a predictive role. The results suggest that occupational accidents may result in a disabling psychopathological condition, and that a brief psychological evaluation should be included in the assessment of seriously injured workers.

OBJECTIVE The purpose of this meta-analysis was to evaluate the impact of perioperative antiepileptic drug (AED) prophylaxis on short- and long-term seizure incidence among patients undergoing brain tumor surgery. It is the first meta-analysis to focus exclusively on perioperative AED prophylaxis among patients undergoing brain tumor surgery. METHODS The authors searched PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and the System for Information on Gray Literature in Europe for records related to perioperative AED prophylaxis for patients with brain tumors. Risk of bias in the included studies was assessed using the Cochrane risk of bias tool. Incidence rates for early seizures (within the first postoperative week) and total seizures were estimated based on data from randomized controlled trials. A Mantel-Haenszel random-effects model was used to analyze pooled relative risk (RR) of early seizures (within the first postoperative week) and total seizures associated with perioperative AED prophylaxis versus control. RESULTS Four RCTs involving 352 patients met the criteria of inclusion. The results demonstrated that perioperative AED prophylaxis for patients undergoing brain tumor surgery provides a statistically significant reduction in risk of early postoperative seizures compared with control (RR = 0.352, 95% confidence interval 0.130-0.949, p = 0.039). AED prophylaxis had no statistically significant effect on the total (combined short- and long-term) incidence of seizures. CONCLUSIONS This meta-analysis demonstrates for the first time that perioperative AED prophylaxis for brain tumor surgery provides a statistically significant reduction in early postoperative seizure risk.

This case study describes post-traumatic stress disorder (PTSD) and head injury after a road traffic accident involving a pedestrian. Previous studies have proposed two mechanisms by which this dual diagnosis may occur: (1) when post-traumatic amnesia and retrograde amnesia are small or non-existent and (2) when non-declarative memory systems for the traumatic event are in operation. This case study demonstrates a third mechanism--"islands" of memory within post-traumatic amnesia.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12th, 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors. PMID:25206499

Preterm birth may represent a traumatic situation for both parents and a stressful situation for the infant, potentially leading to difficulties in mother-infant relationships. This study aimed to investigate the impact of an early intervention on maternal posttraumatic stress symptoms, and on the quality of mother-infant interactions, in a sample of very preterm infants and their mothers. Half of the very preterm infants involved in the study (n=26) were randomly assigned to a 3-step early intervention program (at 33 and 42 weeks after conception and at 4 months' corrected age). Both groups of preterm infants (with and without intervention) were compared to a group of full-term infants. The impact of the intervention on maternal posttraumatic stress symptoms was assessed 42 weeks after conception and when the infants were 4 and 12 months of age. The impact of the intervention on the quality of mother-infant interactions was assessed when the infants were 4 months old. Results showed a lowering of mothers' posttraumatic stress symptoms between 42 weeks and 12 months in the group of preterm infants who received the intervention. Moreover, an enhancement in maternal sensitivity and infant cooperation during interactions was found at 4 months in the group with intervention. In the case of a preterm birth, an early intervention aimed at enhancing the quality of the mother-infant relationship can help to alleviate maternal post-traumatic stress symptoms and may have a positive impact on the quality of mother-infant interactions.

Background Understanding the factors which increase the risk of PTSD for military personnel is important. This study aims to investigate the relative contribution of pre-deployment, peri-deployment, and post deployment variables to the prevalence of post traumatic stress symptoms in UK Armed Forces personnel who have been deployed in Iraq since 2003. Method Data are drawn from stage 1 of a retrospective cohort study comparing a random sample of UK military personnel deployed to the 2003 Iraq War with a control group who were not deployed to the initial phase of war fighting (response rate 61%). The analyses are limited to 4762 regular service individuals who responded and who deployed to Iraq since 2003. Results Post traumatic stress symptoms were associated with lower rank, being unmarried, low educational attainment and a history of childhood adversity. Exposure to potentially traumatising events was associated with post traumatic stress symptoms. Appraisals of the experience as involving threat to life or that work in theatre was above an individual’s trade and experience were strongly associated with post traumatic stress symptoms Low morale, poor social support within the unit and non-receipt of a homecoming brief were associated with greater risk of post traumatic stress symptoms. Conclusions These results support that there are modifiable occupational factors which may influence an individual’s risk of PTSD. Personal appraisal of threat to life during the trauma emerged as the strongest predictor of symptoms, and therefore interventions focused on reinstating a sense of control are an important focus for treatment.

Early-life stress impacts the developing hippocampus and primes seizure occurrence: cellular, molecular, and epigenetic mechanisms

PubMed Central

Huang, Li-Tung

2014-01-01

Early-life stress includes prenatal, postnatal, and adolescence stress. Early-life stress can affect the development of the hypothalamic-pituitary-adrenal (HPA) axis, and cause cellular and molecular changes in the developing hippocampus that can result in neurobehavioral changes later in life. Epidemiological data implicate stress as a cause of seizures in both children and adults. Emerging evidence indicates that both prenatal and postnatal stress can prime the developing brain for seizures and an increase in epileptogenesis. This article reviews the cellular and molecular changes encountered during prenatal and postnatal stress, and assesses the possible link between these changes and increases in seizure occurrence and epileptogenesis in the developing hippocampus. In addititon, the priming effect of prenatal and postnatal stress for seizures and epileptogenesis is discussed. Finally, the roles of epigenetic modifications in hippocampus and HPA axis programming, early-life stress, and epilepsy are discussed. PMID:24574961

Biliary leakage due to a rapidly growing post-traumatic hepatic artery pseudoaneurysm: a case report.

2004-01-01

Post-traumatic hepatic pseudoaneurysms are rare. We report a very unusual case of bile duct injury complicated with an asymptomatic post-traumatic hepatic pseudoaneurysm. A previously healthy 17-year-old man sustained multiple traumas after a motorcycle accident. Post-traumatic hepatic pseudoaneurysms were detected after blunt liver injury. The rapid growth of the pseudoaneurysms in the hepatic hilus compressed the common hepatic bile duct and caused extrahepatic bile leakage at the lateral lobe. At first, the hepatic arterial pseudoaneurysms were embolized and bile leakage at the left lobe was treated conservatively. Finally, however, segment 2 and 3 partial liver resection should have been performed to stop the bile leakage. Post-traumatic pseudoaneurysm should be ruled out, in addition to the presence of biliary tract injury, if the intraperitoneal bile leakage appears after liver injury.

The incidence of late posttraumatic seizures (LPTS) in individuals with traumatic brain injury (TBI) ranges anywhere from 5% to 18.9% in civilian populations up to 32% to 50% in military personnel. This article reviews the current knowledge about the incidence and prevalence of LPTS following a TBI, the risk factors for developing LPTS, and the options available for preventing the development of LPTS. The psychosocial ramifications of LPTS following a TBI have not been well explored. As a result, the psychosocial findings from the current literature on epilepsy will be reviewed with the hope that the need for future TBI outcomes research to investigate the impact of LPTS following a TBI or, at least, to include LPTS as a potential contributing factor will be recognized.

Guilt, shame and need for a container: a study of post-traumatic stress among ambulance personnel.

PubMed

Jonsson, Anders; Segesten, Kerstin

2004-10-01

Post-traumatic stress symptoms among ambulance personnel are regarded as a natural behaviour and reaction to working with the severely injured, suicides, injured children and dead people. The findings show that post-traumatic stress symptoms, guilt, shame and self-reproach are common after duty-related traumatic events. To handle these overwhelming feelings it is necessary to talk about them with fellow workers, friends or family members. By using another person as a container it is possible to internalise the traumatic experience. Poor and un-emphatic behaviour towards a patient and their relatives can have its origin in untreated traumatic experiences. Personnel in ambulance organisations who perform defusing, debriefing and counselling have to be informed of the importance that the roll of guilt and shame may play in the developing of post-traumatic stress symptoms.

Post-traumatic stress disorder and head injury as a dual diagnosis: "islands" of memory as a mechanism.

PubMed Central

King, N S

1997-01-01

This case study describes post-traumatic stress disorder (PTSD) and head injury after a road traffic accident involving a pedestrian. Previous studies have proposed two mechanisms by which this dual diagnosis may occur: (1) when post-traumatic amnesia and retrograde amnesia are small or non-existent and (2) when non-declarative memory systems for the traumatic event are in operation. This case study demonstrates a third mechanism--"islands" of memory within post-traumatic amnesia. PMID:9010405

In China, a growing number of adolescents have experienced traumatic events that have resulted in PTSD (post-traumatic stress disorder). Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare. To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China. A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old) were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ), a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson's correlations, multiple linear regression analyses and structural equation modeling (SEM) were applied to analyze the data. Of the adolescents, 39.76% (N = 2292) had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence) was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms. According to the SEM, parenting style had a significant direct effect on resilience (0.70, P<0.01) and post-traumatic symptoms (-0.15, P<0.05), and resilience had a significant direct effect on the post-traumatic symptoms (-0.43, P<0.01). Furthermore, parenting style had a significant indirect effect (-0.43×0.70 = -0.30. P<0.01) on the post-traumatic symptoms through resilience. The SEM significantly explained 49% of the variance in resilience and 30% of the variance in post-traumatic symptoms. Parenting style and

The aim of this work was to find out whether thinking frequently about the donor influences post-traumatic growth of liver transplant recipients. The sample of 240 patients selected was made up of 185 men and 55 women with an overall mean age of 60.21 (SD 9.3) years. All of them had received liver transplants from cadaver donors. Transplant recipients were asked whether they thought frequently about the donor (yes or no) and filled out the Post-traumatic Growth Inventory. The t test for unpaired samples was applied to analyze how thinking frequently about the donor or not influenced post-traumatic growth. We also calculated the effect sizes by means of Cohen d or Cohen w depending on the nature of the variables analyzed (quantitative or qualitative). The liver transplant recipients who thought frequently about the donor, compared with those who did not, had higher total scores on post-traumatic growth (P = .000; d = 0.57; medium effect size). Furthermore, considering the effect sizes, the differences between the subgroups were more relevant on the following subscales: new possibilities (P = .000; d = 0.53; medium effect size), appreciation of life (P = .000; d = 0.60; medium effect size), and spiritual change (P = .000; d = 0.54; medium effect size). Patients who think frequently about the donor have more post-traumatic growth than those who do not. Copyright © 2017 Elsevier Inc. All rights reserved.

Delayed activation of the primary orbitofrontal cortex in post-traumatic anosmia.

Functional magnetic resonance imaging may help in elucidating the pathophysiology of post-traumatic anosmia. Using an fMRI olfactory stimulus paradigm, this study compared BOLD activation of the brain in a 21-year old male research subject with post-traumatic anosmia and a 19-year old male normal healthy control participant. A delayed activation of the primary orbitofrontal cortex was found in the subject with traumatic anosmia, which may represent a crucial pathophysiological mechanism in the subject with traumatic anosmia due to axonal injury or traumatic transection at the lamina cribrosa level. In healthy subjects the activation of secondary cortical areas may be due to the habituation effect in the primary olfactory cortex. This raises the possibility that, in the absence of secondary activation areas-that may act as a feed-back habituation or desensitization in the patient-one of the primary response areas is activated over the longer period of stimulation. The failed activation of these secondary areas in the patient may cause a feed-back habituation or desensitization in the patient and could also play a role in the disturbed perception of odours.

Posttraumatic seizures (PTS) are well-recognized acute and chronic complications of traumatic brain injury (TBI). Risk factors have been identified, but considerable variability in who develops PTS remains. Existing PTS prognostic models are not widely adopted for clinical use and do not reflect current trends in injury, diagnosis, or care. We aimed to develop and internally validate preliminary prognostic regression models to predict PTS during acute care hospitalization, and at year 1 and year 2 postinjury. Prognostic models predicting PTS during acute care hospitalization and year 1 and year 2 post-injury were developed using a recent (2011-2014) cohort from the TBI Model Systems National Database. Potential PTS predictors were selected based on previous literature and biologic plausibility. Bivariable logistic regression identified variables with a p-value < 0.20 that were used to fit initial prognostic models. Multivariable logistic regression modeling with backward-stepwise elimination was used to determine reduced prognostic models and to internally validate using 1,000 bootstrap samples. Fit statistics were calculated, correcting for overfitting (optimism). The prognostic models identified sex, craniotomy, contusion load, and pre-injury limitation in learning/remembering/concentrating as significant PTS predictors during acute hospitalization. Significant predictors of PTS at year 1 were subdural hematoma (SDH), contusion load, craniotomy, craniectomy, seizure during acute hospitalization, duration of posttraumatic amnesia, preinjury mental health treatment/psychiatric hospitalization, and preinjury incarceration. Year 2 significant predictors were similar to those of year 1: SDH, intraparenchymal fragment, craniotomy, craniectomy, seizure during acute hospitalization, and preinjury incarceration. Corrected concordance (C) statistics were 0.599, 0.747, and 0.716 for acute hospitalization, year 1, and year 2 models, respectively. The prognostic model for PTS

Trauma and stress-related disorders (e.g., Acute Stress Disorder; ASD and Post-Traumatic Stress Disorder; PTSD) that develop following a traumatic event are characterized by cognitive-affective dysfunction. The cognitive and affective functions disrupted by stress disorder are mediated, in part, by glutamatergic neural systems. However, it remains unclear whether neural glutamate concentrations, measured acutely following trauma, vary with ASD symptoms and/or future PTSD symptom expression. Therefore, the current study utilized proton magnetic resonance spectroscopy ( 1 H-MRS) to investigate glutamate/glutamine (Glx) concentrations within the dorsal anterior cingulate cortex (ACC) of recently (i.e., within one month) traumatized individuals and non-traumatized controls. Although Glx concentrations within dorsal ACC did not differ between recently traumatized and non-traumatized control groups, a positive linear relationship was observed between Glx concentrations and current stress disorder symptoms in traumatized individuals. Further, Glx concentrations showed a positive linear relationship with future stress disorder symptoms (i.e., assessed 3 months post-trauma). The present results suggest glutamate concentrations may play a role in both acute and future post-traumatic stress symptoms following a traumatic experience. The current results expand our understanding of the neurobiology of stress disorder and suggest glutamate within the dorsal ACC plays an important role in cognitive-affective dysfunction following a traumatic experience.

This study examined predictors and health-related effects of post-traumatic stress among 129 civilian internees of the Japanese during World War II. Post-traumatic stress disorder was noted in 36.7% within the 6 months after their release and in 15.0% within the most recent 6 months. Women were more likely than men to indicate post-traumatic stress disorder within the 6 months after their release. Higher incomes were associated with lower levels of post-traumatic stress within the most recent 6 months. After controlling for demographic and internment-related factors, higher levels of post-traumatic stress were associated with poorer physical health. This association was stronger among older internees than among their younger counterparts. Implications of the findings for clinical gerontology are discussed.

A confrontation with death can lead to acute reactions of stress, followed possibly, after a phase of latency, by post-traumatic stress disorder (PTSD). PTSD is characterised by the appearance of a repetition syndrome combining reliving, hypervigilance and avoidance; comorbidities frequently arise, increasingthe risk of suicide. Caregivers have an important role to play in identifying them.

Epileptic activity associated with Alzheimer disease (AD) deserves increased attention because it has a harmful impact on these patients, can easily go unrecognized and untreated, and may reflect pathogenic processes that also contribute to other aspects of the illness. We report key features of AD-related seizures and epileptiform activity that are instructive for clinical practice and highlight similarities between AD and transgenic animal models of the disease. To describe common clinical characteristics and treatment outcomes of patients with amnestic mild cognitive impairment (aMCI) or early AD who also have epilepsy or subclinical epileptiform activity. Retrospective observational study from 2007 to 2012. SETTING Memory and Aging Center, University of California, San Francisco. We studied 54 patients with a diagnosis of aMCI plus epilepsy (n = 12), AD plus epilepsy (n = 35), and AD plus subclinical epileptiform activity (n = 7). Clinical and demographic data, electroencephalogram (EEG) readings, and treatment responses to antiepileptic medications. Patients with aMCI who had epilepsy presented with symptoms of cognitive decline 6.8 years earlier than patients with aMCI who did not have epilepsy (64.3 vs 71.1 years; P = .02). Patients with AD who had epilepsy presented with cognitive decline 5.5 years earlier than patients with AD who did not have epilepsy (64.8 vs 70.3 years; P = .001). Patients with AD who had subclinical epileptiform activity also had an early onset of cognitive decline (58.9 years). The timing of seizure onset in patients with aMCI and AD was nonuniform (P < .001), clustering near the onset of cognitive decline. Epilepsies were most often complex partial seizures (47%) and more than half were nonconvulsive (55%). Serial or extended EEG monitoring appeared to be more effective than routine EEG at detecting interictal and subclinical epileptiform activity. Epileptic foci were predominantly unilateral and temporal. Of the

The use of antiepileptic drugs (AEDs) in the neurosurgical setting has a number of implications, including their possible role in the prevention of seizures after acute cerebral insults or brain tumors and the potential for toxicity and interactions when these agents are administered in association with radiotherapy or chemotherapy. This review discusses these controversial issues and draws the following conclusions. 1) AEDs should be prescribed on a short-term basis to prevent seizures occurring within the first week after a cerebral insult (trauma, neurosurgical procedure) but are ineffective to avoid true post-traumatic epilepsy or first seizures in patients with primary or secondary cerebral neoplasms. 2) The use of phenytoin and, to a lesser extent, phenobarbital and carbamazepine during cranial irradiation is associated with an increased risk for severe, potentially fatal, mucocutaneous reactions. In this context, new AEDs with a very low potential for allergic cutaneous reactions should be preferred. 3) Enzyme-inducing AEDs, such as phenytoin, phenobarbital, and carbamazepine, may increase the clearance and reduce the clinical efficacy of corticosteroids and anticancer agents that are also metabolized by the cytochrome P450 system. The newly developed AEDs that are devoid of hepatic metabolism, such as levetiracetam and gabapentin, are now recommended because of good results in preliminary studies and because they do not show interactions with anticancer agents.

Attitudes to emotional expression and personality in predicting post-traumatic stress disorder.

2000-09-01

To test hypotheses derived from a suggestion of Williams (1989) that negative attitudes towards emotional expression act as a predisposing or maintaining factor for post-traumatic stress reactions following a traumatic event. The study employed a prospective design in which attitudes to emotional expression, the 'Big Five' personality factors (Costa & McCrae, 1992a) and initial symptoms and injury severity within 1 week of a road traffic accident were used to predict the development of post-traumatic stress disorder 6 weeks post-accident. Sixty victims of road traffic accidents randomly selected from attenders at a large A&E department were assessed by questionnaire and interview. Measures comprised a 4-item scale relating to emotional expression, standardized scales for intrusion and avoidance features of traumatic experiences, and for anxiety and depression and the NEO-FFI Five Factor Personality Inventory. Forty-five of these participants responded to a postal questionnaire follow-up. In this survey the battery was repeated and also included a self-report diagnostic measure of post-traumatic stress disorder (PTSD). The percentage of the sample meeting DSM-IV diagnostic criteria for PTSD at 6 weeks post-trauma was 30.8%. A small but significant relationship was found for negative attitudes to emotional expression at 1 week to predict intrusive symptoms and diagnosis at 6 weeks, over and above the independent relationships of initial symptoms, initial injury severity, personality and coping. The emotional expression measure was largely stable between the two points of measurement. More negative attitudes to emotional expression were related to less openness, extraversion and agreeableness personality domains. Some support for the hypotheses was found in relation to the development of PTSD and for the status of attitudes to emotion as a stable trait related to personality factors.

Victims of motor vehicle accidents often develop post-traumatic stress disorder, which causes significant social function loss. For the difficulty in treating post-traumatic stress disorder, identification of subjects at high risk for post-traumatic stress disorder is essential for providing possible intervention. This paper aims to examine the cortical structural traits related to susceptibility to post-traumatic stress disorder. To address this issue, we performed structural magnetic resonance imaging study in motor vehicle accident victims within 48 hours from the accidents. A total of 70 victims, available for both clinical and magnetic resonance imaging data, enrolled in our study. Upon completion of 6-month follow-up, 29 of them developed post-traumatic stress disorder, while 41 of them didn't. At baseline, voxelwise comparisons of cortical thickness, cortical area and cortical volume were conducted between post-traumatic stress disorder group and trauma control group. As expected, several reduced cortical volume within frontal-temporal loop were observed in post-traumatic stress disorder. For cortical thickness, no between-group differences were observed. There were three clusters in left hemisphere and one cluster in right hemisphere showing decreased cortical area in post-traumatic stress disorder patients, compared with trauma controls. Peak voxels of the three clusters in left hemisphere were separately located in superior parietal cortex, insula and rostral anterior cingulate cortex. The finding of reduced surface area of left insula and left rostral anterior cingulate cortex suggests that shrinked surface area in motor vehicle accident victims could act as potential biomarker of subjects at high risk for post-traumatic stress disorder.

Phenobarbital increases electroclinical uncoupling and our preliminary observations suggest it may also affect electrographic seizure morphology. This may alter the performance of a novel seizure detection algorithm (SDA) developed by our group. The objectives of this study were to compare the morphology of seizures before and after phenobarbital administration in neonates and to determine the effect of any changes on automated seizure detection rates. The EEGs of 18 term neonates with seizures both pre- and post-phenobarbital (524 seizures) administration were studied. Ten features of seizures were manually quantified and summary measures for each neonate were statistically compared between pre- and post-phenobarbital seizures. SDA seizure detection rates were also compared. Post-phenobarbital seizures showed significantly lower amplitude (p<0.001) and involved fewer EEG channels at the peak of seizure (p<0.05). No other features or SDA detection rates showed a statistical difference. These findings show that phenobarbital reduces both the amplitude and propagation of seizures which may help to explain electroclinical uncoupling of seizures. The seizure detection rate of the algorithm was unaffected by these changes. The results suggest that users should not need to adjust the SDA sensitivity threshold after phenobarbital administration.

As part of the "Joining Forces" Initiative ("JFI"), the White House and nursing leaders announced nurses' commitment to recognize symptoms, provide care, and refer veterans and active duty military members for post-traumatic stress disorder ("PTSD"). The JFI is positioned to save lives through nursing education and raising PTSD awareness. Nurses should also be educated to recognize resilience (stable trajectory of healthy functioning across time following a traumatic event) and assess for post-traumatic growth ("PTG") (positive meaning making) alongside PTSD. In veterans who do develop PTSD, nearly three fourths of them with moderate PTSD will also experience PTG. Nurses' frontline contact with veterans in the VA, private sector healthcare settings, and community enable them to educate veterans and active duty military members about these coping trajectories.

In South Africa, alcohol use poses a public health burden. Hazardous alcohol use often co-occurs with psychological distress (e.g., depression and post-traumatic stress). However, the majority of the research establishing the relationship between alcohol use and psychological distress has been cross-sectional, so the nature of co-occurring changes in psychological distress and alcohol use over time is not well characterized. The objective of this study is to examine the longitudinal relationship between psychological distress and alcohol use among South African women who attend alcohol serving venues. Four waves of data were collected over the course of a year from 560 women in a Cape Town township who attended drinking venues. At each assessment wave, participants reported depressive symptoms, post-traumatic stress symptoms, and alcohol use. Multilevel growth models were used to: 1) assess the patterns of alcohol use; 2) examine how depressive symptoms uniquely, post-traumatic stress symptoms uniquely, and depressive and post-traumatic stress symptoms together were associated with alcohol use; and 3) characterize the within person and between person associations of depressive symptoms and post-traumatic stress symptoms with alcohol use. Women reported high levels of alcohol use throughout the study period, which declined slightly over time. Post-traumatic stress symptoms were highly correlated with depressive symptoms. Modeled separately, both within person and between person depressive and post-traumatic stress symptoms were uniquely associated with alcohol use. When modeled together, significant between person effects indicated that women who typically have more post-traumatic stress symptoms, when controlling for depressive symptoms, are at risk for increased alcohol use; however, women with more depressive symptoms, controlling for post-traumatic stress symptoms, do not have differential risk for alcohol use. Significant within person effects indicated an

Post-traumatic stress disorder (PTSD) is an anxiety disorder arising from exposure to a traumatic event. Although primarily defined in terms of behavioral symptoms, the global neurophysiological effects of traumatic stress are increasingly recognized as a critical facet of the human PTSD phenotype. Here we use magnetoencephalographic recordings to investigate two aspects of information processing: inter-regional communication (measured by functional connectivity) and the dynamic range of neural activity (measured in terms of local signal variability). We find that both measures differentiate soldiers diagnosed with PTSD from soldiers without PTSD, from healthy civilians, and from civilians with mild traumatic brain injury, which is commonly comorbid with PTSD. Specifically, soldiers with PTSD display inter-regional hypersynchrony at high frequencies (80-150 Hz), as well as a concomitant decrease in signal variability. The two patterns are spatially correlated and most pronounced in a left temporal subnetwork, including the hippocampus and amygdala. We hypothesize that the observed hypersynchrony may effectively constrain the expression of local dynamics, resulting in less variable activity and a reduced dynamic repertoire. Thus, the re-experiencing phenomena and affective sequelae in combat-related PTSD may result from functional networks becoming "stuck" in configurations reflecting memories, emotions, and thoughts originating from the traumatizing experience. The present study investigates the effects of post-traumatic stress disorder (PTSD) in combat-exposed soldiers. We find that soldiers with PTSD exhibit hypersynchrony in a circuit of temporal lobe areas associated with learning and memory function. This rigid functional architecture is associated with a decrease in signal variability in the same areas, suggesting that the observed hypersynchrony may constrain the expression of local dynamics, resulting in a reduced dynamic range. Our findings suggest that

A single unprovoked seizure is a frequent phenomenon in the general population and the rate of seizure recurrence can vary widely. Individual risk prognostication is crucial in predicting patient outcomes and guiding treatment decisions. In this article, we review the most important risk factors associated with an increased likelihood of seizure recurrence after a single unprovoked seizure. In summary, the presence of focal seizure, nocturnal seizure, history of prior brain injury, family history of epilepsy, abnormal neurological exam, epileptiform discharges on electroencephalography and neuroimaging abnormalities, portend increased risk of seizure recurrence. Elucidation of these risk factors in patient assessment will augment clinical decision-making and may help determine the appropriateness of instituting anti-epilepsy treatment. We also discuss the Canadian model of single seizure clinics and the potential use to assess these patients. Copyright © 2017. Published by Elsevier Ltd.

Psychotrauma occurs as a result to a traumatic event, which may involve witnessing someone's actual death or personally experiencing serious physical injury, assault, rape and sexual abuse, being held as a hostage, or a threat to physical or psychological integrity. Post-traumatic stress disorder (PTSD) is an anxiety disorder and was defined in the past as railway spine, traumatic war neurosis, stress syndrome, shell shock, battle fatigue, combat fatigue, or post-traumatic stress syndrome (PTSS). If untreated, post-traumatic stress disorder can impair relationships of those affected and strain their families and society. Deployed soldiers are especially at a high risk to be affected by PTSD but often receive inadequate treatment. Reviews to date have focused only on a single type of treatment or groups of soldiers from only one country. The aim of the current review was to evaluate characteristics of therapeutic methods used internationally to treat male soldiers' PTSD after peacekeeping operations in South Eastern Europe and the Gulf wars. This systematic literature review returned results pertaining to the symptoms, diagnosis, timing and effectiveness of treatment. Sample groups and controls were relatively small and, therefore, the results lack generalizability. Further research is needed to understand the influence and unique psychological requirements of each specific military operation on the internationally deployed soldiers. PMID:19643016

Early traumatic events in psychopaths.

The relationship between diverse early traumatic events and psychopathy was studied in 194 male inmates. Criminal history transcripts were revised, and clinical interviews were conducted to determine the level of psychopathy using the Psychopathy Checklist-Revised (PCL-R) Form, and the Early Trauma Inventory was applied to assess the incidence of abuse before 18 years of age. Psychopathic inmates presented a higher victimization level and were more exposed to certain types of intended abuse than sociopathic inmates, while the sum of events and emotional abuse were associated with the PCL-R score. Our studies support the influence of early adverse events in the development of psychopathic offenders. © 2013 American Academy of Forensic Sciences.

To determine whether lung retrieval from traumatic donors performed within 24 h of brain death has a negative impact on early graft function and survival after lung transplantation (LT), when compared with those retrieved after 24 h. Review of lung transplants performed from traumatic donors over a 17-year period. Recipients were distributed into two groups: transplants from traumatic donor lungs retrieved within 24 h of brain death (Group A), and transplants from traumatic donor lungs retrieved after 24 h of brain death (Group B). Demographic data of donors and recipients, early graft function, perioperative complications and mortality were compared between both groups. Among 356 lung transplants performed at our institution, 132 were from traumatic donors (70% male, 30% female). Group A: 73 (55%); Group B: 59 (45%). There were 53 single, 77 double, and 2 combined LT. Indications were emphysema in 41 (31%), pulmonary fibrosis in 31 (23%), cystic fibrosis in 38 (29%), bronchiectasis in 9 (7%) and other indications in 13 patients (10%). Donor and recipient demographic data, need or cardiopulmonary bypass, postoperative complications and Intensive Care Unit and hospital stay did not differ between groups. Primary graft dysfunction (A vs B): 9 (16%) vs 13 (26%) P = 0.17. PaO2/FiO2 24 h post-transplant (A vs B): 303 mmHg vs 288 mmHg (P = 0.57). Number of acute rejection episodes (A vs B): 0.93 vs 1.49 (P = 0.01). Postoperative intubation time (A vs B): 99 vs 100 h (P = 0.99). 30-day mortality (A vs B): 7 (10%) vs 2 (3.5%) (P = 0.13). Freedom from bronchiolitis obliterans syndrome (A vs B): 82, 72, 37, 22 vs 78, 68, 42, 15%, at 3, 5, 10 and 15 years, respectively (P = 0.889). Survival (A vs B): 65, 54, 46, 42 and 27 vs 60, 50, 45, 43 and 29% at 3, 5, 7, 10 and 15 years, respectively (P = 0.937). In our experience, early lung retrieval after brain death from traumatic donors does not adversely affect early and long-term outcomes after LT.

Mild traumatic brain injury (TBI) persistent post-concussion syndrome (PPCS) and post-traumatic stress disorder (PTSD) are epidemic in United States Iraq and Afghanistan War veterans. Treatment of the combined diagnoses is limited. The aim of this study is to assess safety, feasibility, and effectiveness of hyperbaric oxygen treatments (HBOT) for mild TBI PPCS and PTSD. Thirty military subjects aged 18–65 with PPCS with or without PTSD and from one or more blast-induced mild-moderate traumatic brain injuries that were a minimum of 1 year old and occurred after 9/11/2001 were studied. The measures included symptom lists, physical exam, neuropsychological and psychological testing on 29 subjects (1 dropout) and SPECT brain imaging pre and post HBOT. Comparison was made using SPECT imaging on 29 matched Controls. Side effects (30 subjects) experienced due to the HBOT: reversible middle ear barotrauma (n = 6), transient deterioration in symptoms (n = 7), reversible bronchospasm (n = 1), and increased anxiety (n = 2; not related to confinement); unrelated to HBOT: ureterolithiasis (n = 1), chest pain (n = 2). Significant improvement (29 subjects) was seen in neurological exam, symptoms, intelligence quotient, memory, measures of attention, dominant hand motor speed and dexterity, quality of life, general anxiety, PTSD, depression (including reduction in suicidal ideation), and reduced psychoactive medication usage. At 6-month follow-up subjects reported further symptomatic improvement. Compared to Controls the subjects' SPECT was significantly abnormal, significantly improved after 1 and 40 treatments, and became statistically indistinguishable from Controls in 75% of abnormal areas. HBOT was found to be safe and significantly effective for veterans with mild to moderate TBI PPCS with PTSD in all four outcome domains: clinical medicine, neuropsychology, psychology, and SPECT imaging. Veterans also experienced a significant reduction in suicidal ideation and reduction

Background: Post traumatic growth (PTG) can be defined as positive change following a traumatic event. The current conceptualization of PTG encompasses five main dimensions, however, there is no dimension which accounts for the distinct effect of a physical trauma on PTG. The purpose of the present research was to test the role of PTG, physical post traumatic growth (PPTG), resilience and mindfulness in predicting psychological and health related adjustment. Method: Ethical approval was obtained from relevant institutional ethics committees. Participants ( N = 241), who were at least 1 year post prostate cancer treatment, were invited to complete a battery of questionnaires either through an online survey or a paper and pencil package received in the post The sample ranged in age from 44 to 88 years ( M = 64.02, SD = 7.76). Data were analysis using confirmatory factor analysis and structural equation modeling. Results: The physical post traumatic growth inventory (P-PTGI) was used to evaluate the role of PPTG in predicting adjustment using structural equation modeling. P-PTGI predicted lower distress and improvement of quality of life, whereas conversely, the traditional PTG measure was linked with poor adjustment. The relationship between resilience and adjustment was found to be mediated by P-PTGI. Conclusion: Findings suggest the central role of PTG in the prostate cancer survivorship experience is enhanced by the inclusion of PPTG. Adjusting to a physical trauma such as illness (internal transgressor) is unlike a trauma with an external transgressor as the physical trauma creates an entirely different framework for adjustment. The current study demonstrates the impact of PPTG on adjustment. This significantly adds to the theory of the development of PTG by highlighting the interplay of resilience with PTG, PPTG, and adjustment.

Predictors of post-traumatic stress symptoms in Oklahoma City: exposure, social support, peri-traumatic responses.

Tucker, P; Pfefferbaum, B; Nixon, S J; Dickson, W

2000-11-01

Eighty-five adults seeking mental health assistance six months after the Oklahoma City bombing were assessed to determine which of three groups of variables (exposure, peri-traumatic responses, and social support) predicted development of post-traumatic stress disorder (PTSD) symptoms. Variables most highly associated with subsequent PTSD symptoms included having been injured (among exposure variables), feeling nervous or afraid (peri-traumatic responses), and responding that counseling helped (support variables). Combining primary predictors in the three areas, PTSD symptoms were more likely to occur in those reporting counseling to help and those feeling nervous or afraid at the time of the bombing. Implications of these findings are discussed for behavioral health administrators and clinicians planning service delivery to groups of victims seeking mental health intervention after terrorist attacks and other disasters.

The objectives of this study were to examine differences in social participation among Veterans with spinal cord injuries/disorders with and without post-traumatic stress disorder, and determine if lower social participation was independently associated with having post-traumatic stress disorder. A cross-sectional mailed national survey was sent to a national sample of Veterans with spinal cord injuries/disorders who received prior-year Veterans Affairs healthcare. Surveys provided data on: demographics, health conditions, injury characteristics, and social participation. Analyses included bivariate comparisons, and multivariate logistic regression to determine if lower social participation was independently associated with post-traumatic stress disorder. Veterans with (vs. without) post-traumatic stress disorder (n = 896) reported lower social participation (40.2 vs. 43.9, p < 0.0001). Multivariate analyses showed that longer duration of injury (OR = 0.98, 95% CI: 0.97-1.00, p = 0.04) and white race (OR = 0.62, 95% CI: 0.38-1.01, p = 0.05) were associated with lower odds of post-traumatic stress disorder, while a greater number of health conditions (OR = 1.43, 95% CI: 1.25-1.64, p < 0.0001) was associated with greater odds. When controlling for covariates, lower social participation was independently associated with post-traumatic stress disorder (OR = 0.94, 95% CI: 0.90-0.98, p = 0.003). Results indicate post-traumatic stress disorder is associated with lower social participation in Veterans with spinal cord injuries/disorders, independent of other factors that may impact participation. Efforts to screen for and treat post-traumatic stress disorder among persons with spinal cord injuries/disorders, regardless of injury-specific factors, are needed to improve participation. Implications for Rehabilitation Individuals with spinal cord injuries/disorders often have post-traumatic stress disorder; in Veterans with spinal cord

Post-traumatic external nasal pain syndrome (a trigeminal based pain disorder).

PubMed

Rozen, Todd

2009-09-01

Little has been written about persistent external nasal pain after injury to the nose in the neurologic or headache literature. In clinical practice, this can be a disabling and treatment refractory condition. The external portion of the nose is highly innervated by branches of the ophthalmic and maxillary divisions of the trigeminal nerve including the nasociliary nerve, external nasal nerve, infratrochlear nerve, anterior ethmoidal nerve, and infraorbital nerve. As these nerves are located on the external portion of the nose just deep enough to the skin they can be easily traumatized with any impact to the nose. Four patients with what is termed the post-traumatic external nasal pain syndrome are reported in this paper, describing the clinical presentation of the disorder and providing treatment options. Post-traumatic external nasal pain syndrome appears to be a novel form of trigeminal-based pain not previously reported in the neurologic literature.

Treating post-traumatic tremor with deep brain stimulation: report of five cases.

Post-traumatic tremor is one of the most common movement disorders resulting from severe head trauma. However, literature regarding successful deep brain stimulation (DBS) treatment is scarce, resulting in ambiguity regarding the optimal lead location. Most cases support the ventral intermediate nucleus, but there is evidence to defend DBS of the zona incerta, ventral oralis anterior/posterior, and/or a combination of these targets. We report five patients with disabling post-traumatic tremor treated with DBS of the ventral intermediate nucleus and of the globus pallidus internus. Patients were referred to the Vanderbilt Movement Disorders Division, and surgical intervention was determined by a DBS Multidisciplinary Committee. Standard DBS procedure was followed. Patients 1-4 sustained severe diffuse axonal injuries. Patients 1-3 underwent unilateral ventral intermediate nucleus DBS for contralateral tremor, while Patient 4 underwent bilateral ventral intermediate nucleus DBS. Patients 1-3 experienced good tremor reduction, while Patient 4 experienced moderate tremor reduction with some dystonic posturing of the hands. Patient 5 had dystonic posturing of the right upper extremity with tremor of the left upper extremity. He was treated with bilateral DBS of the globus pallidus internus and showed good tremor reduction at follow-up. Unilateral or bilateral DBS of the ventral intermediate nucleus and bilateral DBS of the globus pallidus internus may be effective and safe treatment modalities for intractable post-traumatic tremor. Further studies are needed to clarify the optimal target for surgical treatment of post-traumatic tremor. Published by Elsevier Ltd.

Mild traumatic brain injury (mTBI) accounts for most cases of TBI, and many patients show incomplete long-term functional recovery. We aimed to create a prognostic model for functional outcome by combining demographics, injury severity, and psychological factors to identify patients at risk for incomplete recovery at 6 months. In particular, we investigated additional indicators of emotional distress and coping style at 2 weeks above early predictors measured at the emergency department. The UPFRONT study was an observational cohort study done at the emergency departments of three level-1 trauma centres in the Netherlands, which included patients with mTBI, defined by a Glasgow Coma Scale score of 13-15 and either post-traumatic amnesia lasting less than 24 h or loss of consciousness for less than 30 min. Emergency department predictors were measured either on admission with mTBI-comprising injury severity (GCS score, post-traumatic amnesia, and CT abnormalities), demographics (age, gender, educational level, pre-injury mental health, and previous brain injury), and physical conditions (alcohol use on the day of injury, neck pain, headache, nausea, dizziness)-or at 2 weeks, when we obtained data on mood (Hospital Anxiety and Depression Scale), emotional distress (Impact of Event Scale), coping (Utrecht Coping List), and post-traumatic complaints. The functional outcome was recovery, assessed at 6 months after injury with the Glasgow Outcome Scale Extended (GOSE). We dichotomised recovery into complete (GOSE=8) and incomplete (GOSE≤7) recovery. We used logistic regression analyses to assess the predictive value of patient information collected at the time of admission to an emergency department (eg, demographics, injury severity) alone, and combined with predictors of outcome collected at 2 weeks after injury (eg, emotional distress and coping). Between Jan 25, 2013, and Jan 6, 2015, data from 910 patients with mTBI were collected 2 weeks after injury; the final

Non-ablative, fractional lasers generate microscopic columns of coagulated tissue through the epidermis and dermis to evoke a wound healing response. In this study, the authors examined the efficacy and safety of the non-ablative 1540 nm erbium:glass fractional laser in the treatment of surgical and post-traumatic scars. Clinical studies were conducted on a range of surgical and post-traumatic scars with a 1540 nm erbium:glass fractional laser varying energy, pulse widths, treatment passes, and number of treatments. A histological study was conducted on a postsurgical scar to follow the time course of healing post-treatment and the impact of the fractional treatment on normalization of scar tissue, as compared to baseline histology of the scar. Histologic findings demonstrated rapid re-epithelialization of the epidermis within 72 hours of treatment. Remodeling of scar tissue with renewal and reorganization of collagen fibers in the dermis was noted two weeks post-treatment. Clinical subjects, with Fitzpatrick skin types II-V, received three to seven treatments with microbeam energies up to 60 mJ/pb and five passes. Relative to baseline, 73% of treated scars improved 50% or more and 43% improved 75% or more. Side effects included mild swelling (95% of subjects), erythema (94%) and purpura (5%), which all resolved within two to three days. Downtime was minimal-to-none for all subjects. These data illustrate the safety and efficacy of the 1540 nm erbium:glass fractional laser in the treatment of surgical and post-traumatic scars. Practitioners can vary energy and microbeam density in order to tailor the treatment to reflect the individual scar characteristics.

Symptoms of post-traumatic distress in mothers of preterm infants have been a subject of mental health research. The aim of this study was to assess the prevalence of and risk factors associated with such symptoms in mothers of preterm infants in Taiwan. This was a cross-sectional study performed between January 1, 2010 and June 30, 2011. One hundred and two mothers of preterm infants born at less than 37 weeks gestation and with a subsequent neonatal intensive care unit (NICU) stay between 2005 and 2009 were recruited. Participants completed a demographic questionnaire, the Impact of Event Scale-Revised (IES-R), the Center for Epidemiologic Studies Depression Scale (CES-D) and the neuroticism subscale of the Maudsley Personality Inventory (MPI). The preterm infants' data were taken from medical records. The prevalence of symptoms of distress was 25.5% (26/102) in the participants. These symptoms were associated with previous miscarriages, preterm premature rupture of membranes, neurotic personality and depression. The experience of preterm birth and NICU hospitalization can be traumatic to mothers. Early support for mothers during the preterm infants' NICU stay and transition to home care are recommended.

This study evaluated the factors associated with post-traumatic stress symptoms in Korean adolescents who lived in a disaster-affected community. A total of 1101 students attending secondary and high schools in Jindo, the location of the Sewol ferry disaster, were enrolled in a cross-sectional survey. The Child Report of Post-traumatic Symptoms (CROPS), the Center for Epidemiological Studies Depression Scale (CES-D), and the State Anxiety Inventory for Children (SAIC) were administered. Female gender, older children, poor academic achievement, and directly witnessing the rescue scene were associated with post-traumatic stress symptoms. The CES-D and SAIC scores of subjects with witness of the rescue were significantly higher than those of respondents without such experiences. The regression analysis revealed that directly witnessing the rescue scene was significantly associated with post-traumatic stress symptoms after adjusting for other variables. The results of this study suggest that witnessing the rescue scene following a disaster might be a risk factor for post-traumatic stress symptoms in adolescents in disaster-affected communities.

There has been no comprehensive investigation of psychological health in Australia's Korean War veteran population, and few researchers are investigating the health of coalition Korean War veterans into old age. To investigate the association between war service, anxiety, post-traumatic stress disorder (PTSD) and depression in Australia's 7525 surviving male Korean War veterans and a community comparison group. A survey was conducted using a self-report postal questionnaire which included the PTSD Checklist, the Hospital Anxiety and Depression scale and the Combat Exposure Scale. Post-traumatic stress disorder (OR 6.63, P<0.001), anxiety (OR 5.74, P<0.001) and depression (OR 5.45, P<0.001) were more prevalent in veterans than in the comparison group. These disorders were strongly associated with heavy combat and low rank. Effective intervention is necessary to reduce the considerable psychological morbidity experienced by Korean War veterans. Attention to risk factors and early intervention will be necessary to prevent similar long-term psychological morbidity in veterans of more recent conflicts.

To assess the prevalence of hypopituitarism following traumatic brain injury (TBI), describe the time-course and assess the association with trauma-related parameters and early post-traumatic hormone alterations. A 12-month prospective study. Forty-six consecutive patients with TBI (mild: N = 22; moderate: N = 9; severe: N = 15). Baseline and stimulated hormone concentrations were assessed in the early phase (0-12 days post-traumatically), and at 3, 6 and 12 months postinjury. Pituitary tests included the Synacthen-test (acute +6 months) and the insulin tolerance test (ITT) or the GHRH + arginine test if the ITT was contraindicated (3 + 12 months). Insufficiencies were confirmed by retesting. Early post-traumatic hormone alterations mimicking central hypogonadism or hypothyroidism were present in 35 of the 46 (76%) patients. Three months post-traumatically, 6 of the 46 patients failed anterior pituitary testing. At 12 months, one patient had recovered, whereas none developed new insufficiencies. All insufficient patients had GH deficiency (5 out of 46), followed by ACTH- (3 out of 46), TSH- (1 out of 46), LH/FSH- (1 out of 46) and ADH deficiency (1 out of 46). Hypopituitary patients had more frequently been exposed to severe TBI (4 out of 15) than to mild or moderate TBI (1 out of 31) (P = 0.02). Early endocrine alterations including lowered thyroid and gonadal hormones, and increased total cortisol, free cortisol and copeptin were positively associated to TBI severity (P < 0.05), but not to long-term development of hypopituitarism (P > 0.1), although it was indicative in some. Long-term hypopituitarism was frequent only in severe TBI. During the 3-12 months follow-up, recovery but no new insufficiencies were recorded, indicating manifest hypothalamic or pituitary damage already a few months postinjury. Very early hormone alterations were not associated to long-term post-traumatic hypopituitarism. Clinicians should, nonetheless, be aware of potential ACTH

The management of complete or partial urethral disruption is controversial, and much debate continues regarding immediate versus delayed definitive therapy. We further analyze our experience and long-term results using early endoscopic realignment. Between April 1987 and January 1999, 29 men with posterior urethral disruption (23 complete and 6 partial) underwent primary urethral realignment 0 to 8 days after injury. Pelvic fractures were present in 23 patients. In all patients, the actual operating time for realignment was 75 minutes or less. All patients were evaluated postoperatively for incontinence, impotence, and strictures. After a mean follow-up of 68 months (range 18 to 155), all patients were continent. Four patients (13.7%) required conversion to an open perineal urethroplasty. At the last follow-up visit, 25 (86%) of the 29 patients were potent and 4 achieved adequate erections for intercourse using intracorporeal injections (prostaglandin E(1)). Twelve patients (41%) developed short secondary strictures and were successfully treated with internal urethrotomy. The mean follow-up of these 12 patients was 83 months (range 34 to 120). Urinary flow rate measurement at the last follow-up visit revealed satisfactory voiding parameters in all patients. Primary endoscopic realignment offers an effective method for treating traumatic urethral injuries. Our long-term follow-up provides additional support for the use of this technique by demonstrating that urethral continuity can be established without an increased incidence of impotence, stricture formation, or incontinence. In case of failure, endoscopic realignment does not compromise the result of secondary urethroplasty.

Fear of childbirth and obstetrical events as predictors of postnatal symptoms of depression and post-traumatic stress disorder.

Fairbrother, Nichole; Woody, Sheila R

2007-12-01

This prospective study examined psychological and obstetrical predictors of enduring postpartum symptoms of depression and post-traumatic stress disorder. Contrary to prediction, prenatal fear of childbirth did not significantly predict symptoms of depression or post-traumatic stress disorder at one month postpartum, but anxiety sensitivity was an unexpected predictor that merits further investigation. Several obstetrical and neonatal variables significantly predicted symptoms of post-traumatic disorder, but not depression.

The purpose of this study was to determine if serum microRNA (miRNA) signatures were biomarkers of early cartilage degeneration in preclinical mouse models of post-traumatic osteoarthritis (OA) and inflammatory arthritis. Cartilage degeneration was induced in 10-12 week old male C57BL6 mice by destabilization of the medial meniscus (DMM) or intra-articular injection of methylated-bovine-serum-albumin (AIA), with sham-operated or saline-injected control animals (n = 6/treatment/time). Total serum RNA and knee joints were isolated at 1, 4 and 16 weeks post-induction. Cartilage degeneration was scored histologically. Serum miRNA expression profiling was performed using Agilent microarrays and validated by qPCR. DMM-operated and AIA mice had characteristic cartilage degeneration (proteoglycan loss, chondrocyte hypertrophy, structural damage), that increased significantly with time compared with controls, and with distinct temporal differences between arthritis models. However, expression profiling revealed no statistically significant dysregulation of serum miRNAs between AIA vs saline-injected or DMM vs sham-operated control mice at the critical early disease stages. The inability to detect DMM or AIA serum miRNA signatures compared with controls was not due to the insensitivity of the expression profiling approach since significant changes were observed in miRNA expression between the arthritis models and between time points. While distinct patterns of progressive cartilage degradation were induced in the arthritis models, we were unable to identify any serum miRNAs that were significantly dysregulated in early stages of disease compared with controls. This suggests circulating serum miRNAs may not be useful as cartilage biomarkers in distinguishing the early or progressive stages of arthritis cartilage degeneration.

Children exposed to disaster: I. Epidemiology of post-traumatic symptoms and symptom profiles.

To determine the range and severity of post-traumatic stress disorder (PTSD) symptoms exhibited by children after exposure to a natural disaster. Three months after Hurricane Hugo struck Berkeley County, South Carolina, 5,687 school-aged children were surveyed about their experiences and reactions related to the storm. Self-reports of PTSD symptoms were obtained by use of a PTSD Reaction Index. Significant variation in the prevalence of PTSD symptoms was found across race, gender, and age groups. Self-reported symptoms were used to derive a post-traumatic stress syndrome classification according to DSM-III-R guidelines for the diagnosis of PTSD. More than 5% of the sample reported sufficient symptoms to be classified as exhibiting this post-traumatic stress syndrome. Females and younger children were more likely to receive this classification. At the symptom level, females reported more symptoms associated with emotional processing and emotional reaction to the trauma. Males were more likely to report symptoms related to cognitive and behavioral factors. Younger children were more likely to report symptoms overall. Children exposed to a high magnitude natural disaster report sufficient symptoms to establish a DSM-III-R derived classification of a PTSD syndrome. Differences between gender, age, and race groups appear to be related to differential risk of exposure, reporting biases, as well as a differential risk for developing post-traumatic symptoms.

The validity of applying the construct of post-traumatic stress disorder (PTSD) across cultures has been the subject of contention. Although PTSD symptoms have been identified across multiple cultures, questions remain whether the constellation represents a coherent construct with an interpretable factor structure across diverse populations, especially those naïve to western notions of mental disorder. An important additional question is whether a constellation of Complex-PTSD (C-PTSD) can be identified and if so, whether there are distinctions between that disorder and core PTSD in patterns of antecedent traumatic events. Our study amongst West Papuan refugees in Papua New Guinea (PNG) aimed to examine the factorial structure of PTSD based on the DSM-IV, DSM-5, ICD-10 and ICD-11 definitions, and C-PTSD according to proposed ICD-11 criteria. We also investigated domains of traumatic events (TEs) and broader psychosocial effects of conflict (sense of safety and injustice) associated with the factorial structures identified. Culturally adapted measures were applied to assess exposure to conflict-related traumatic events (TEs), refugees' sense of safety and justice, and symptoms of PTSD and C-PTSD amongst 230 West Papuan refugees residing in Port Morseby, PNG. Confirmatory factor analysis (CFA) supported a unitary construct of both ICD-10 and ICD-11 PTSD, comprising the conventional symptom subdomains of intrusion, avoidance, and hyperarousal. In contrast, CFA did not identify a unitary construct underlying C-PTSD. The interaction of witnessing murders and sense of injustice was associated with both the intrusion and avoidance domains of PTSD, but not with the unique symptom clusters characterizing C-PTSD. Our findings support the ICD PTSD construct and its three-factor structure in this transcultural refugee population. Traumatic experiences of witnessing murder associated with a sense of injustice were specifically related to the intrusion and avoidance domains of

The current study examined whether trauma characteristics such as the type and number of traumatic events were associated with three suicidal behaviours (i.e. ideation, plan and attempt) after adjusting for sociodemographic factors, post-traumatic symptoms and history of psychiatric disorders. Data came from the 2007 Australian National Survey of Mental Health and Wellbeing ( N = 8841). Respondents were asked about exposure to 28 traumatic events that occurred during their lifetime. Suicidal behaviours were measured using three statements about whether the person ever seriously thought about or planned or attempted suicide. Sexual violence and exposure to multiple traumatic events were particularly associated with suicidal behaviours. The presence of the emotional numbing symptom cluster and co-occurrence of three psychiatric disorders (major depressive disorder, alcohol use disorder and substance use disorder) also increased the odds of suicidal behaviours. Analysis of age of onset revealed that the mean age of traumatic exposure was earlier than the age at which suicidal behaviours emerged. The current study is the first to demonstrate that sexual violence and exposure to multiple traumatic events are associated with suicidal behaviours in a representative sample of Australian adults. The results underline the potential benefits of thorough assessment of trauma history, post-traumatic symptoms and history of psychiatric disorders and their additive contribution in suicide risk among trauma victims. These findings can be used by clinicians and researchers for early intervention programmes.

Post-War Research on Post-Traumatic Stress Disorder. Part I. Research before 1989.

The paper presents the post-war history of post-traumatic research conducted at the Department of Psychiatry of the Jagiellonian University and the analysis of the main research approaches and selected publications. The time after World War II passed in Poland in two directions: coping with the finished war trauma and simultaneously the experience of communist persecution trauma. First scientific publications appeared in the fifties and were focused on the research of former concentration camps prisoners (KZ-Syndrome). Between 1962 and 1989 a special edition of Przegląd Lekarski, which concentrated entirely on war trauma research, was published. The journal was nominated for the Peace Nobel Prize twice. The research team from the Department of Psychiatry headed by Professor Antoni Kępiński made a very extensive description of KZ-Syndrome issues. The paper summarizes the most important contemporary research findings on psychopathology of KZ-Syndrome (Szymusik), reaction dynamics (Teutsch), after camp adjustment (Orwid), paroxysmal hypermnesia (Półtawska), somatic changes (Gatarski, Witusik). The result of the study was the basis for the development of a methodology and a new look at the classification of the consequences of post-traumatic stress disorder, as well as the development of ethical attitudes towards patients.

Delayed-onset post-traumatic headache after a motor vehicle collision: a case report

PubMed Central

Stupar, Maja; Kim, Peter SY

2007-01-01

Introduction Headaches are common after a motor vehicle accident (MVA). Post-traumatic headaches share many clinical symptoms including the clinical course of primary headaches. Secondary headaches (including those resulting from a subdural hematoma) are not as common, but should be considered in cases of post-traumatic events particularly if clinical symptoms progress. Clinical Features A case of a patient with a post-traumatic subdural hematoma demonstrates the importance of carefully examining, properly diagnosing and managing patients that experience headaches after MVAs. This patient presented with uncomplicated low back pain, neck pain and headache which progressed at one month to include focal neurological deficits. Since clinical examination alone may not be sufficient to diagnose secondary headaches, immediate referral to the emergency department may be required. Conclusion Primary contact practitioners should be aware of the various causes of headaches that result after a MVA. Headaches, which do not respond or progress, should be followed aggressively to determine their source. PMID:17657301

Post-traumatic hepatic artery pseudoaneurysm is uncommon, appearing in approximately 1% of hepatic trauma cases. Most are extrahepatic (80%) and have a late onset. Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications, especially breakage. Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices. Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection. We present a case of post-traumatic hepatic artery pseudoaneurysm that was successfully treated using this combined technique.

Dysfunctional cognitions related to trauma is an important factor in the development and maintenance of post-traumatic stress disorder symptoms in children and adolescents. The Child Post-traumatic Cognitions Inventory (CPTCI) assesses such cognitions about trauma. We investigated the psychometric properties of the Korean version of CPTCI and its short form by surveying child and adolescent survivors of sexual violence. Children and adolescents aged 7-16 years ( N  = 237, M age  = 12.6, SD  = 2.3, 222 [93.7%] were female) who were exposed to sexual violence were included in this survey. We assessed the factor structure, internal consistency, and validity of the CPTCI and its short form through data analysis. Confirmatory factor analysis results supported the two-factor model presented in the original study. The total scale, its subscales, and the short form had good internal consistency (Cronbach's α = .96 for total scale and .91-.95 for the other scales). The CPTCI showed high correlations with scales measuring post-traumatic stress symptoms ( r  = .77-.80), anxiety ( r  = .69-.71), and depression ( r  = .74-.77); the correlation with post-traumatic stress symptoms was the highest. The differences in CPTCI scores per post-traumatic stress symptom levels were significant (all p  < .001) Sex differences in CPTCI scores were not significant ( p  > .05 for all comparisons); however, the scores exhibited differences per age group (all p  < .001). The results indicate that the Korean version of the CPTCI is a valid and reliable scale; therefore, it may be a valuable tool for assessing maladaptive cognitions related to trauma in research and clinical settings.

To examine cognitive activity limitations and predictors of outcome 1 year post-trauma in patients admitted to sub-acute rehabilitation after severe traumatic brain injury. The study included 119 patients with severe traumatic brain injury admitted to centralized sub-acute rehabilitation in the Eastern part of Denmark during a 5-year period from 2005 to 2009. Level of consciousness was assessed consecutively during rehabilitation and at 1 year post-trauma. Severity of traumatic brain injury was classified according to duration of post-traumatic amnesia. The cognitive subscale of Functional Independence MeasureTM (Cog-FIM) was used to assess cognitive activity limitations. Multivariate logistic regression analyses were performed to identify predictors of an independent level of functioning. The majority of patients progressed to a post-confusional level of consciousness during the first year post-trauma. At follow-up 33-58% of patients had achieved functional independence within the cognitive domains on the Cog-FIM. Socio-economic status, duration of acute care and post-traumatic amnesia were significant predictors of outcome. Substantial recovery was documented among patients with severe traumatic brain injury during the first year post-trauma. The results of the current study suggest that absence of consciousness at discharge from acute care should not preclude patients from being referred to specialized sub-acute rehabilitation.

Transnasal Endoscopic Optic Nerve Decompression in Post Traumatic Optic Neuropathy.

To quantify the successful outcome in patients following optic nerve decompression in post traumatic unilateral optic neuropathy in form of improvement in visual acuity. A prospective study was carried out over a period of 5 years (January 2011 to June 2016) at civil hospital Ahmedabad. Total 20 patients were selected with optic neuropathy including patients with direct and indirect trauma to unilateral optic nerve, not responding to conservative management, leading to optic neuropathy and subsequent impairment in vision and blindness. Decompression was done via Transnasal-Ethmo-sphenoidal route and outcome was assessed in form of post-operative visual acuity improvement at 1 month, 6 months and 1 year follow up. After surgical decompression complete recovery of visual acuity was achieved in 16 (80%) patients and partial recovery in 4 (20%). Endoscopic transnasal approach is beneficial in traumatic optic neuropathy not responding to steroid therapy and can prevent permanent disability if earlier intervention is done prior to irreversible damage to the nerve. Endoscopic optic nerve surgery can decompress the traumatic and oedematous optic nerve with proper exposure of orbital apex and optic canal without any major intracranial, intraorbital and transnasal complications.

The purpose of this investigation was to study basal cerebral glucose absorption patterns associated to long-term post-traumatic stress disorder. Fluorodeoxyglucose positron emission tomography (FDG-PET) and statistic parametric mapping (SPM) were used to compare regional cerebral glucose absorption between 15 war veterans (Hispanic men, aged 39-41 (M = 39.5, SD = 0.84)) diagnosed with post-traumatic stress disorder (PTSD) based on DSM-IV criteria, and a matching control group of six asymptomatic veterans. This study was conducted 20 years after the traumatic events. PTSD patients presented relatively diminished activity (P<0.005) in: cingulate gyri, precuneus, insula, hippocampus; frontal, pre-frontal and post-central regions; lingual, calcarine, occipital medial and superior gyri, and verbal and paraverbal areas. Relativeley augmented activity (P<0.005) was observed in PTSD patients in: fusiform, temporal superior, medial, and inferior gyri; occipital medial, inferior and lingual gyri; precuneus, and cerebellum. The amygdala and the thalamus showed normal metabolic activity. Various brain regions that showed diminished activity (limbic, frontal and prefrontal cortex, multimodal parieto-occipital areas and verbal and paraverbal areas) have evolved lately, and sub-serve highly complex cognitive and behavioural functions. Metabolic activity patterns are comparable to those observed in personality disorders of the borderline type.

2018-01-01

A growing body of research suggests that counterfactual thinking after traumatic events is associated with post-traumatic stress reactions. In this study we explored frequency of upward and downward counterfactuals in trauma-exposed individuals, and how trauma-related counterfactuals were represented in terms of vividness. We examined the relationships between vividness and frequency of counterfactual thoughts and post-traumatic stress reactions in two groups who had experienced different types of traumatic exposure, namely survivors and bereaved from the fire on the ferry Scandinavian Star in 1990. Even after 26 years, both survivors and bereaved reported that they currently entertained thoughts about what could have happened during the fire on Scandinavian Star. Survivors reported more downward counterfactuals than the bereaved, whereas the bereaved reported more upward counterfactuals than the survivors did. Vividness of counterfactual thoughts, as well as reported frequency of upward and downward counterfactuals, were associated with post-traumatic stress reactions. Our results suggest that both upward and downward counterfactuals can be harmful, and that vivid counterfactuals about a traumatic event might play a similar role in post-traumatic stress as trauma memories. Therefore, traumatized individuals who entertain counterfactual thoughts may benefit from interventions that target these thoughts specifically.

White matter integrity in highly traumatized adults with and without post-traumatic stress disorder.

Prior structural imaging studies of post-traumatic stress disorder (PTSD) have observed smaller volumes of the hippocampus and cingulate cortex, yet little is known about the integrity of white matter connections between these structures in PTSD samples. The few published studies using diffusion tensor imaging (DTI) to measure white matter integrity in PTSD have described individuals with focal trauma rather than chronically stressed individuals, which limits generalization of findings to this population; in addition, these studies have lacked traumatized comparison groups without PTSD. The present DTI study examined microstructural integrity of white matter tracts in a sample of highly traumatized African-American women with (n=25) and without (n=26) PTSD using a tract-based spatial statistical approach, with threshold-free cluster enhancement. Our findings indicated that, relative to comparably traumatized controls, decreased integrity (measured by fractional anisotropy) of the posterior cingulum was observed in participants with PTSD (p<0.05). These findings indicate that reduced microarchitectural integrity of the cingulum, a white matter fiber that connects the entorhinal and cingulate cortices, appears to be associated with PTSD symptomatology. The role of this pathway in problems that characterize PTSD, such as inadequate extinction of learned fear, as well as attention and explicit memory functions, are discussed.

To evaluate pain incidence and intensity in patients undergoing septorhinoplasty, and to assess analgesic treatment effectiveness, in the first 7 days after surgery. Prospective outcomes analysis using visual analogue scale assessment of pain intensity in the first 7 post-operative days. Fifty-seven patients were enrolled in the study, 29 women and 28 men, aged 18 to 51 years. All were treated for post-traumatic deformity of the external nose and/or nasal septum, with either septorhinoplasty or septoplasty. In the first 3 days after septorhinoplasty, patients' mean visual analogue scale pain score exceeded the range denoting 'analgesic success', and showed considerable exacerbation in the evening. Patients' pain decreased to a mean score of 15.4 one hour after administration of a nonsteroidal anti-inflammatory drug (metamizole). Analgesia is recommended for all patients in the first 3 days after septorhinoplasty, especially in the early evening.

Use of electroconvulsive therapy (ECT) is limited by cognitive disturbance. Focal electrically-administered seizure therapy (FEAST) is designed to initiate focal seizures in the prefrontal cortex. To date, no studies have documented the effects of FEAST on regional cerebral blood flow (rCBF). A 72 year old depressed man underwent three single photon emission computed tomography (SPECT) scans to capture the onset and resolution of seizures triggered with right unilateral FEAST. We used Bioimage Suite for within-subject statistical analyses of perfusion differences ictally and post-ictally compared with the baseline scan. Early ictal increases in regional cerebral blood flow (rCBF) were limited to the right prefrontal cortex. Post-ictally, perfusion was reduced in bilateral frontal and occipital cortices and increased in left motor and precuneus cortex. FEAST appears to triggers focal onsets of seizure activity in the right prefrontal cortex with subsequent generalization. Future studies are needed on a larger sample. Copyright © 2014 Elsevier Inc.

Continuous EEG (cEEG) is necessary to document nonconvulsive seizures (NCS), nonconvulsive status epilepticus (NCSE), as well as rhythmic and periodic EEG patterns of 'ictal-interictal uncertainty' (RPPIIU) including periodic discharges, rhythmic delta activity, and spike-and-wave complexes in neurological intensive care patients. However, cEEG is associated with significant recording and analysis efforts. Therefore, predictors from short-term routine EEG with a reasonably high yield are urgently needed in order to select patients for evaluation with cEEG. The aim of this study was to assess the prognostic significance of early epileptiform discharges (i.e., within the first 30 min of EEG recording) on the following: (1) incidence of ictal EEG patterns and RPPIIU on subsequent cEEG, (2) occurrence of acute convulsive seizures during the ICU stay, and (3) functional outcome after 6 months of follow-up. We conducted a separate analysis of the first 30 min and the remaining segments of prospective cEEG recordings according to the ACNS Standardized Critical Care EEG Terminology as well as NCS criteria and review of clinical data of 32 neurological critical care patients. In 17 patients with epileptiform discharges within the first 30 min of EEG (group 1), electrographic seizures were observed in 23.5% (n = 4), rhythmic or periodic EEG patterns of 'ictal-interictal uncertainty' in 64.7% (n = 11), and neither electrographic seizures nor RPPIIU in 11.8% (n = 2). In 15 patients with no epileptiform discharges in the first 30 min of EEG (group 2), no electrographic seizures were recorded on subsequent cEEG, RPPIIU were seen in 26.7% (n = 4), and neither electrographic seizures nor RPPIIU in 73.3% (n = 11). The incidence of EEG patterns on cEEG was significantly different between the two groups (p = 0.008). Patients with early epileptiform discharges developed acute seizures more frequently than patients without early epileptiform discharges (p = 0.009). Finally, functional

Hypopituitarism may often occur in association with traumatic brain injury (TBI). Identification of reliable predictors of pituitary dysfunction is of importance in order to establish a rational testing approach. We searched the records of patients with TBI, who underwent neuroendocrine evaluation in our institution between 2007 and 2013. One hundred sixty-six adults (70% men) with TBI (median age: 41.6 years; range: 18-76) were evaluated at a median interval of 40.4 months (0.2-430.4).Of these, 31% had ≥1 pituitary deficiency, including 29% of patients with mild TBI and 35% with moderate/severe TBI. Growth hormone deficiency was the most common deficiency (21%); when body mass index (BMI)-dependent cutpoints were used, this was reduced to 15%. Central hypoadrenalism occurred in10%, who were more likely to have suffered a motor vehicle accident (MVA, p = 0.04), experienced post-traumatic seizures (p = 0.04), demonstrated any intracranial hemorrhage (p = 0.05), petechial brain hemorrhages (p = 0.017), or focal cortical parenchymal contusions (p = 0.02). Central hypothyroidism occurred in 8% and central hypogonadism in 12%; the latter subgroup had higher BMI (p = 0.03), were less likely to be working after TBI (p = 0.002), and had lower Global Assessment of Functioning (GAF) scores (p = 0.03). Central diabetes insipidus (DI) occurred in 6%, who were more likely to have experienced MVA (p < 0.001) or sustained moderate/severe TBI (p < 0.001). Patients with MVA and those with post-traumatic seizures, intracranial hemorrhage, petechial brain hemorrhages, and/or focal cortical contusions are at particular risk for serious pituitary dysfunction, including adrenal insufficiency and DI, and should be referred for neuroendocrine testing. However, a substantial proportion of patients without these risk factors also developed hypopituitarism.

The study investigated associations between workplace bullying and post-traumatic stress symptoms as compared to and controlled for associations between the latter and other psychosocial stress factors at work and in everyday life. The study employed a representative sample of Lithuanian family physicians, hence investigated a particularly resourceful occupational group in a geographical region earlier found to have a high risk context for exposure to bullying at work. With a response rate of 89.2%, a total of 323 family physicians filled in an anonymous questionnaire on workplace bullying, post-traumatic symptomatology (IES-R), other psychosocial stressors at work and in everyday life, personal health resources (sense of coherence), behavioral characteristics and demographic variables. The statistical software SPSS 14.0, Windows was used in the analysis. Associations were tested using a multivariate logistic regression analysis. A high prevalence of bullying was found among family physicians in Lithuania, with 13% of them experiencing severe workplace bullying and 17.3% experiencing more occasional incidents of bullying. The prevalence of post-traumatic stress symptoms was also high with 15.8% scoring above the standardized cut-off thresholds for post-traumatic stress disorder. The odds ratio (OR) of severe bullying for post-traumatic stress after adjustment for age and gender was 8.05 (95% confidence intervals (CI): 3.80-17.04). In the fully adjusted model it increased to 13.88 (95% CI: 4.68-41.13) indicating cumulative effects of all the investigated stressors. Workplace bullying is particularly prevalent among Lithuanian family physicians, as are the symptoms of post-traumatic distress. Strong associations between post-traumatic stress and exposure to severe bullying indicate that bullying is a significant source of mental health.

Animal models of post-traumatic stress disorder: face validity

Post-traumatic stress disorder (PTSD) is a debilitating condition that develops in a proportion of individuals following a traumatic event. Despite recent advances, ethical limitations associated with human research impede progress in understanding PTSD. Fortunately, much effort has focused on developing animal models to help study the pathophysiology of PTSD. Here, we provide an overview of animal PTSD models where a variety of stressors (physical, psychosocial, or psychogenic) are used to examine the long-term effects of severe trauma. We emphasize models involving predator threat because they reproduce human individual differences in susceptibility to, and in the long-term consequences of, psychological trauma. PMID:23754973

Anterior cruciate ligament injury results in altered kinematics and kinetics in the knee and hip joints that persist despite surgical reconstruction and rehabilitation. Abnormal movement patterns and a history of osteoarthritis are risk factors for articular cartilage degeneration in additional joints. The purpose of this study was to determine if hip joint biomechanics early after anterior cruciate ligament injury and reconstruction differ between patients with and without post-traumatic knee osteoarthritis 5years after reconstruction. The study's rationale was that individuals who develop knee osteoarthritis after anterior cruciate ligament injury may also demonstrate large alterations in hip joint biomechanics. Nineteen athletes with anterior cruciate ligament injury completed standard gait analysis before (baseline) and after (post-training) extended pre-operative rehabilitation and at 6months, 1year, and 2years after reconstruction. Weightbearing knee radiographs were completed 5years after reconstruction to identify medial compartment osteoarthritis. Five of 19 patients had knee osteoarthritis at 5years after anterior cruciate ligament reconstruction. Patients with knee osteoarthritis at 5years walked with smaller sagittal plane hip angles (P: 0.043) and lower sagittal (P: 0.021) and frontal plane (P: 0.042) external hip moments in the injured limb before and after reconstruction compared to those without knee osteoarthritis. The current findings suggest hip joint biomechanics may be altered in patients who develop post-traumatic knee osteoarthritis. Further study is needed to confirm whether the risk of non-traumatic hip pathology is increased after anterior cruciate ligament injury and if hip joint biomechanics influence its development.

Herodotus' account of the Athenian spear carrier Epizelus' psychogenic mutism following the Marathon Wars is usually cited as the first documented account of post-traumatic stress disorders in historical literature. This paper describes much earlier accounts of post combat disorders that were recorded as occurring in Mesopotamia (present day Iraq) during the Assyrian dynasty (1300-609 BC). The descriptions in this paper include many symptoms of what we would now identify in current diagnostic classification systems as post-traumatic stress disorders; including flashbacks, sleep disturbance and low mood. The Mesopotamians explain the disorder in terms of spirit affliction; the spirit of those enemies whom the patient had killed during battle causing the symptoms.

Combat veterans, mental health issues, and the death penalty: addressing the impact of post-traumatic stress disorder and traumatic brain injury.

More than 1.5 million Americans have participated in combat operations in Iraq and Afghanistan over the past seven years. Some of these veterans have subsequently committed capital crimes and found themselves in our nation's criminal justice system. This Essay argues that combat veterans suffering from post-traumatic stress disorder or traumatic brain injury at the time of their offenses should not be subject to the death penalty.Offering mitigating evidence regarding military training, post-traumatic stress disorder, and traumatic brain injury presents one means that combat veterans may use to argue for their lives during the sentencing phase of their trials. Alternatively, Atkins v. Virginia and Roper v. Simmons offer a framework for establishing a legislatively or judicially created categorical exclusion for these offenders, exempting them from the death penalty as a matter of law. By understanding how combat service and service-related injuries affect the personal culpability of these offenders, the legal system can avoid the consequences of sentencing to death America's mentally wounded warriors, ensuring that only the worst offenders are subject to the ultimate punishment.

Seizures are common during the neonatal period, often due to hypoxic-ischemic encephalopathy and may contribute to acute brain injury and the subsequent development of cognitive deficits and childhood epilepsy. Here we explored short- and long-term consequences of neonatal hypoxia-induced seizures in 7 day old C57BL/6J mice. Seizure activity, molecular markers of hypoxia and histological injury were investigated acutely after hypoxia and response to chemoconvulsants and animal behaviour was explored at adulthood. Hypoxia was induced by exposing pups to 5% oxygen for 15 min (global hypoxia). Electrographically defined seizures with behavioral correlates occurred in 95% of these animals and seizures persisted for many minutes after restitution of normoxia. There was minimal morbidity or mortality. Pre- or post-hypoxia injection of phenobarbital (50mg/kg) had limited efficacy at suppressing seizures. The hippocampus from neonatal hypoxia-seizure mice displayed increased expression of vascular endothelial growth factor and the immediate early gene c-fos, minimal histological evidence of cell injury and activation of caspase-3 in scattered neurons. Behavioral analysis of mice five weeks after hypoxia-induced seizures detected novel anxiety-related and other behaviors, while performance in a spatial memory test was similar to controls. Seizure threshold tests with kainic acid at six weeks revealed that mice previously subject to neonatal hypoxia-induced seizures developed earlier, more frequent and longer-duration seizures. This study defines a set of electro-clinical, molecular, pharmacological and behavioral consequences of hypoxia-induced seizures that indicate short- and long-term deleterious outcomes and may be a useful model to investigate the pathophysiology and treatment of neonatal seizures in humans.

See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit. We prospectively enrolled 16 patients admitted to the intensive care unit for acute severe traumatic brain injury to test two hypotheses: (i) in patients who lack behavioural evidence of language expression and comprehension, functional magnetic resonance imaging and electroencephalography detect command-following during a motor imagery task (i.e. cognitive motor dissociation) and association cortex responses during language and music stimuli (i.e. higher-order cortex motor dissociation); and (ii) early responses to these paradigms are associated with better 6-month outcomes on the Glasgow Outcome Scale-Extended. Patients underwent functional magnetic resonance imaging on post-injury Day 9.2 ± 5.0 and electroencephalography on Day 9.8 ± 4.6. At the time of imaging, behavioural evaluation with the Coma Recovery Scale-Revised indicated coma (n = 2), vegetative state (n = 3), minimally conscious state without language (n = 3), minimally conscious state with language (n = 4) or post-traumatic confusional state (n = 4). Cognitive motor dissociation was identified in four patients, including three whose behavioural diagnosis suggested a vegetative state. Higher-order cortex motor dissociation was identified in two additional patients. Complete absence of responses to language, music and motor imagery was only observed in coma patients.

Post-traumatic stress disorder is pervasive in low- and middle-income countries. There is evidence to suggest that post-traumatic stress disorder is more common among people living with HIV than non-infected matched controls. We carried out a systematic review of interventions for adult post-traumatic stress disorder from resource poor settings with a focus on people living with HIV. We included all studies that investigated interventions for adult post-traumatic stress disorder from resource poor settings with a focus on interventions that were either randomised controlled trials or observational cohort studies carried out from 1980 to May 2015. Of the 25 articles that were identified for full review, two independent reviewers identified seven studies that met our study inclusion criteria. All randomised controlled trials (RCT) (n = 6) used cognitive behavioural therapy-based interventions and focused on people living with HIV in resource poor settings. There was only one study focusing on the use of lay counsellors to address post-traumatic stress disorder but core competencies were not described. There were no intervention studies from Africa, only an observational cohort study from Rwanda. Rigorously evaluated interventions for adult post-traumatic stress disorder in people living with HIV are rare. Most were undertaken in resource poor settings located in high-income countries. There is a need for research on the development and implementation of appropriate interventions for post-traumatic stress disorder in people living with HIV in low- and middle-income countries. © 2016 John Wiley & Sons Ltd.

The aim of this study was to evaluate the role of resource-oriented variables such as self-efficacy, locus of control (LOC) and post-traumatic growth (PTG) in predicting treatment response in older adults with post-traumatic stress. Fifty-eight older adults with subsyndromal or greater severity of war-associated post-traumatic stress disorder (PTSD) symptoms completed a randomized controlled Internet-based cognitive-behavioural therapy (CBT) with immediate and delayed treatment groups. Assessments of PTSD severity and resource-oriented variables of self-efficacy, LOC and PTG were conducted at baseline, post-treatment and at a 6-month follow-up. Results revealed that pre-treatment scores on measures of internal LOC and PTG predicted PTSD symptom severity at post-treatment, even after controlling for initial PTSD. At a 6-month follow-up, internal LOC continued to predict PTSD symptom severity. In addition, repeated-measures analyses of variance revealed that, relative to older adults with low internal LOC and PTG, older adults with high internal LOC and PTG, respectively, did not differ with respect to initial PTSD severity, but they showed a more pronounced response to treatment. These findings suggest that greater locus of control and post-traumatic growth is associated with greater improvement in PTSD symptoms following Internet-based CBT. Assessment of these constructs may be useful in identifying trauma survivors who are most likely to respond to CBT. Greater internal locus of control and post-traumatic growth is associated with greater improvement in PTSD symptoms following Internet-based CBT. Older adults with initial high internal locus of control and post-traumatic growth, respectively, did not differ with respect to initial PTSD severity, but they showed a more pronounced response to treatment. It could be assumed that patients with initial functional appraisals could benefit easier and faster from a trauma-focused cognitive-behavioural therapy compared to

The aim of epilepsy models is to investigate disease ontogenesis and therapeutic interventions in a consistent and prospective manner. The kainic acid-induced status epilepticus (KASE) rat model is a widely used, well-validated model for temporal lobe epilepsy (TLE). As we noted significant variability within the model between labs potentially related to the rat strain used, we aimed to describe two variants of this model with diverging seizure phenotype and neuropathology. In addition, we evaluated two different protocols to induce status epilepticus (SE). Wistar Han (Charles River, France) and Sprague-Dawley (Harlan, The Netherlands) rats were subjected to KASE using the Hellier kainic acid (KA) and a modified injection scheme. Duration of SE and latent phase were characterized by video-electroencephalography (vEEG) in a subgroup of animals, while animals were sacrificed 1 week (subacute phase) and 12 weeks (chronic phase) post-SE. In the 12 weeks post-SE groups, seizures were monitored with vEEG. Neuronal loss (neuronal nuclei), microglial activation (OX-42 and translocator protein), and neurodegeneration (Fluorojade C) were assessed. First, the Hellier protocol caused very high mortality in WH/CR rats compared to SD/H animals. The modified protocol resulted in a similar SE severity for WH/CR and SD/H rats, but effectively improved survival rates. The latent phase was significantly shorter (p < 0.0001) in SD/H (median 8.3 days) animals compared to WH/CR (median 15.4 days). During the chronic phase, SD/H rats had more seizures/day compared to WH/CR animals (p < 0.01). However, neuronal degeneration and cell loss were overall more extensive in WH/CR than in SD/H rats; microglia activation was similar between the two strains 1 week post-SE, but higher in WH/CR rats 12 weeks post-SE. These neuropathological differences may be more related to the distinct neurotoxic effects of KA in the two rat strains than being the outcome of seizure burden

Recently, the topic of traumatic brain injury has gained attention in both the scientific community and lay press. Similarly, there have been exciting developments on multiple fronts in the area of neurochemistry specifically related to purine biology that are relevant to both neuroprotection and neurodegeneration. At the 2105 meeting of the National Neurotrauma Society, a session sponsored by the International Society for Neurochemistry featured three experts in the field of purine biology who discussed new developments that are germane to both the pathomechanisms of secondary injury and development of therapies for traumatic brain injury. This included presentations by Drs. Edwin Jackson on the novel 2',3'-cAMP pathway in neuroprotection, Detlev Boison on adenosine in post-traumatic seizures and epilepsy, and Michael Schwarzschild on the potential of urate to treat central nervous system injury. This mini review summarizes the important findings in these three areas and outlines future directions for the development of new purine-related therapies for traumatic brain injury and other forms of central nervous system injury. In this review, novel therapies based on three emerging areas of adenosine-related pathobiology in traumatic brain injury (TBI) were proposed, namely, therapies targeting 1) the 2',3'-cyclic adenosine monophosphate (cAMP) pathway, 2) adenosine deficiency after TBI, and 3) augmentation of urate after TBI. © 2016 International Society for Neurochemistry.

Virtual Reality-Enhanced Extinction of Phobias and Post-Traumatic Stress.

Virtual reality (VR) refers to an advanced technological communication interface in which the user is actively participating in a computer-generated 3-dimensional virtual world that includes computer sensory input devices used to simulate real-world interactive experiences. VR has been used within psychiatric treatment for anxiety disorders, particularly specific phobias and post-traumatic stress disorder, given several advantages that VR provides for use within treatment for these disorders. Exposure therapy for anxiety disorder is grounded in fear-conditioning models, in which extinction learning involves the process through which conditioned fear responses decrease or are inhibited. The present review will provide an overview of extinction training and anxiety disorder treatment, advantages for using VR within extinction training, a review of the literature regarding the effectiveness of VR within exposure therapy for specific phobias and post-traumatic stress disorder, and limitations and future directions of the extant empirical literature.

Onyx embolization of cerebral arteriovenous malformations (AVM) has become increasingly common. We explored the risk of seizures after Onyx use.A retrospective review was conducted of 20 patients with supratentorial brain arteriovenous malformation (AVM) who received Onyx embolization between 2006 and 2009. Baseline demographics, clinical history, seizure history, AVM characteristics and treatment were compared between those who developed post-onyx seizure and those who did not. MRIs were reviewed for edema following Onyx treatment.Of 20 patients who underwent Onyx embolization, the initial AVM presentation was hemorrhage in 40% (N=8). The median number of embolizations was two (range 1-4) and the median final obliteration amount was 90% (range 50-100%). A history of seizure was present in 50% (N=10) of patients pre-embolization and 12 (60%) patients received seizure medications (treatment or prophylaxis) prior to embolization. Seizur post-Onyx embolization occurred in 45% (N=9). The median time to seizur post-Onyx was seven days (range 0.3-210). Four patients (20%) with seizures post-Onyx had no seizure history. Two of these patients (10%) had no other identifiable cause for seizure other than recent Onyx embolization. Seizures in these two patients occurred within 24 hours of Onyx administration. Among patients with post-Onyx seizures, there was a trend toward larger AVM size (P=0.091) and lower percent obliteration (P=0.062). Peri-AVM edema was present in 75% of MRIs performed within one month of Onyx treatment and may represent a possible etiology for seizures.New onset seizures post-Onyx embolization are not uncommon. Further study of seizure prevention is warranted.

Objective To evaluate the effectiveness of cognitive therapy for post-traumatic stress disorder related to terrorism and other civil conflict in Northern Ireland. Design Randomised controlled trial. Setting Community treatment centre, Northern Ireland. Participants 58 consecutive patients with chronic post-traumatic stress disorder (median 5.2 years, range 3 months to 32 years) mostly resulting from multiple traumas linked to terrorism and other civil conflict. Interventions Immediate cognitive therapy compared with a waiting list control condition for 12 weeks followed by treatment. Treatment comprised a mean of 5.9 sessions during 12 weeks and 2.0 sessions thereafter. Main outcome measures Primary outcome measures were patients' scores for post-traumatic stress disorder (post-traumatic stress diagnostic scale) and depression (Beck depression inventory). The secondary outcome measure was scores for occupational and social functioning (work related disability, social disability, and family related disability) on the Sheehan disability scale. Results At 12 weeks after randomisation, immediate cognitive therapy was associated with significantly greater improvement than the waiting list control group in the symptoms of post-traumatic stress disorder (mean difference 9.6, 95% confidence interval 3.6 to 15.6), depression (mean difference 10.1, 4.8 to 15.3), and self reported occupational and social functioning (mean difference 1.3, 0.3 to 2.5). Effect sizes from before to after treatment were large: post-traumatic stress disorder 1.25, depression 1.05, and occupational and social functioning 1.17. No change was observed in the control group. Conclusion Cognitive therapy is an effective treatment for post-traumatic stress disorder related to terrorism and other civil conflict.

mTOR is activated in epilepsy, but the mechanisms of mTOR activation in post-traumatic epileptogenesis are unknown. It is also not clear whether mTOR inhibition has an anti-epileptogenic, or merely anticonvulsive effect. The rat hippocampal organotypic culture model of post-traumatic epilepsy was used to study the effects of long-term (four weeks) inhibition of signaling pathways that interact with mTOR. Ictal activity was quantified by measurement of lactate production and electrical recordings, and cell death was quantified with lactate dehydrogenase (LDH) release measurements and Nissl-stained neuron counts. Lactate and LDH measurements were well correlated with electrographic activity and neuron counts, respectively. Inhibition of PI3K and Akt prevented activation of mTOR, and was as effective as inhibition of mTOR in reducing ictal activity and cell death. A dual inhibitor of PI3K and mTOR, NVP-BEZ235, was also effective. Inhibition of mTOR with rapamycin reduced axon sprouting. Late start of rapamycin treatment was effective in reducing epileptic activity and cell death, while early termination of rapamycin treatment did not result in increased epileptic activity or cell death. The conclusions of the study are as follows: (1) the organotypic hippocampal culture model of post-traumatic epilepsy comprises a rapid assay of anti-epileptogenic and neuroprotective activities and, in this model (2) mTOR activation depends on PI3K-Akt signaling, and (3) transient inhibition of mTOR has sustained effects on epilepsy.

Post-traumatic stress disorder--a diagnostic and therapeutic challenge.

In Germany, the one-month prevalence of post-traumatic stress disorder (PTSD) is in the range of 1% to 3%. Soldiers, persons injured in accidents, and victims of domestic violence increasingly seek medical help for symptoms of emotional stress. Days lost from work and monetary compensation for emotional disturbances are markedly on the rise. The term "PTSD" is commonly used uncritically and imprecisely, with too little regard for the existing diagnostic criteria. It is at risk of turning into a nonspecific collective term for emotional stress of any kind. We selectively reviewed the literature in the PubMed database and pertinent journals, with additional consideration of the recommendations and guidelines of medical societies from Germany and abroad. The characteristic types of reactions seen in PTSD are nightmares and an intense, repetitive, intrusive "reliving" of the traumatic event(s). Emotional traumatization manifests itself not only as PTSD but also through major effects on other mental and somatic diseases. An early, trauma-focused behavioral therapeutic intervention involving several sessions, generally on an outpatient basis, can prevent the development of PTSD. The most important components of effective treatment are a focus on the particular trauma experienced and confrontation with the patient's memories of the trauma. The best existing evidence is for cognitive therapy, behavioral therapy according to the exposure paradigm of Foa, and eye movement desensitization and reprocessing therapy. The most recent meta-analysis reveals effect strengths of g = 1.14 for all types of psychotherapy and g = 0.42 for all types of pharmacotherapy taken together (with considerable differences among psychotherapeutic methods and among drugs). The efficacy of psychodynamic therapy, systemic therapy, body-oriented therapy, and hypnotherapy has not been adequately documented in randomized controlled trials. PTSD can be precisely diagnosed and effectively treated when the

Given the recent peak in refugee numbers and refugees' high odds of developing post-traumatic stress disorder (PTSD), finding ways to alleviate PTSD in refugees is of vital importance. However, there are major differences in PTSD treatment response between refugees, the determinants of which are largely unknown. This study aimed at improving PTSD treatment for adult refugees by identifying PTSD treatment response predictors. A prospective longitudinal multilevel modelling design was used to predict PTSD severity scores over time. We analysed data from a randomized controlled trial with pre-, post-, and follow-up measurements of the safety and efficacy of eye movement desensitization and reprocessing and stabilization in asylum seekers and refugees suffering from PTSD. Lack of refugee status, comorbid depression, demographic, trauma-related and treatment-related variables were analysed as potential predictors of PTSD treatment outcome. Treatment outcome data from 72 participants were used. The presence (B = 6.5, p = .03) and severity (B = 6.3, p < .01) of a pre-treatment depressive disorder predicted poor treatment response and explained 39% of the variance between individuals. Refugee patients who suffer from PTSD and severe comorbid depression benefit less from treatment aimed at alleviating PTSD. Results highlight the need for treatment adaptations for PTSD and comorbid severe depression in traumatized refugees, including testing whether initial targeting of severe depressive symptoms increases PTSD treatment effectiveness. There are differences in post-traumatic stress disorder (PTSD) treatment response between traumatized refugees. Comorbid depressive disorder and depression severity predict poor PTSD response. Refugees with PTSD and severe depression may not benefit from PTSD treatment. Targeting comorbid severe depression before PTSD treatment is warranted. This study did not correct for multiple hypothesis testing. Comorbid depression may

The aims of this preliminary study were to explore the suitability for and benefits of commencing dysarthria treatment for people with traumatic brain injury (TBI) while in post-traumatic amnesia (PTA). It was hypothesized that behaviours in PTA don't preclude participation and dysarthria characteristics would improve post-treatment. A series of comprehensive case analyses. Two participants with severe TBI received dysarthria treatment focused on motor speech deficits until emergence from PTA. A checklist of neurobehavioural sequelae of TBI was rated during therapy and perceptual and motor speech assessments were administered before and after therapy. Results revealed that certain behaviours affected the quality of therapy but didn't preclude the provision of therapy. Treatment resulted in physiological improvements in some speech sub-systems for both participants, with varying functional speech outcomes. These findings suggest that dysarthria treatment can begin and provide short-term benefits to speech production during the late stages of PTA post-TBI.

Post-traumatic fatigue (PTF) is a common, disabling, and often chronic symptom following traumatic brain injury (TBI). Yet, the impact of chronic cognitive and physical fatigue and their associations with psychiatric, sleep, cognitive, and psychosocial sequelae in mild-moderate TBI remain poorly understood. Sixty Veterans with a history of mild-moderate TBI and 40 Veteran controls (VC) were administered the Modified Fatigue Impact Scale, a validated measure of TBI-related cognitive and physical fatigue as well as measures of neuropsychiatric, psychosocial, sleep, and objective cognitive functioning. Compared to VC, TBI Veterans endorsed significantly greater levels of cognitive and physical fatigue. In TBI, psychiatric symptoms, sleep disturbance, and post-traumatic amnesia (PTA) were associated with both cognitive and physical fatigue, while loss of consciousness (LOC) and poor attention/processing speed were related to elevations in cognitive fatigue only. In regression analyses, anxiety, sleep disturbance, and LOC significantly predicted cognitive fatigue, while only post-traumatic stress symptoms and PTA contributed to physical fatigue. Cognitive and physical fatigue are problematic symptoms following mild-moderate TBI that are differentially associated with specific injury and psychiatric sequelae. Findings provide potential symptom targets for interventions aimed at ameliorating fatigue, and further underscore the importance of assessing and treating fatigue as a multi-dimensional symptom following TBI.

to systematically identify interventions that midwives could introduce to address post-traumatic stress in women following childbirth. a search strategy was developed and relevant papers were identified from databases including Cinahl, Cochrane Library, EMBASE, Maternity and Infant Care, MEDLINE, PsycINFO, and Web of Science. Key search terms used were post-traumatic stress, post partum, intervention, controlled trial and review. Papers eligible for inclusion were primary studies and reviews of research published from 2002-2012, focusing on interventions which could be implemented by midwives for the prevention and/or management of PTSD. For primary studies, RCTs, controlled clinical trials, and cohort studies with a control group were eligible. Eligible reviews were those with a specified search strategy and inclusion/exclusion criteria. Methodological quality was assessed using recognised frameworks. six primary studies and eight reviews were eligible for inclusion. The majority of included studies or reviews focused on debriefing and/or counselling interventions; however the results were not consistent due to significant variation in methodological quality and use of dissimilar interventions. Two of the reviews considered the general management of post partum PTSD and one broadly covered anxiety during pregnancy and the post partum, incorporating a section on PTSD. The majority of women reported that the opportunity to discuss their childbirth experience was subjectively beneficial. no evidence-based midwifery interventions were identified from this systematic review that can be recommended for introduction into practice to address PTSD. It is recommended that future research in this area should incorporate standardised interventions with similar outcome measures to facilitate synthesis of results. Further research on interventions used in non-maternity populations is needed in order to confirm their usefulness in addressing post partum PTSD. © 2013 Elsevier

To examine the prevalence of post-traumatic stress disorder symptoms and to explore the predictive factors of post-traumatic stress disorder symptoms among bereaved adolescents four years after the Yushu earthquake. On 14 April 2010, the 7·1-magnitude Yushu earthquake occurred in the high-altitude, hypoxia-prone regions primarily inhabited by ethnic minorities. Many adolescents lost their parents during the earthquake. This study examined post-traumatic stress disorder and its predictors among bereaved Tibetan adolescents four years after the trauma in China. This was a cross-sectional descriptive study. This study used a cross-sectional design with 830 bereaved adolescents. Participant demographic data included gender, age and grade, and the earthquake exposure variables included the deceased relatives, whether they were buried, injured or amputated (non-life-threatening) and whether they witnessed a burial, injury or death. The post-traumatic stress disorder Checklist-Civilian version was used to assess the symptoms and prevalence of post-traumatic stress disorder, and the Coping Style Scale assessed coping styles. The results indicated that the prevalence of post-traumatic stress disorder was 19·3%. Individuals who were buried, injured or amputated (non-life-threatening), who witnessed a burial, injury or death, who suffered severe property loss during the earthquake and who had negative coping skills were the most likely individuals to have post-traumatic stress disorder symptoms. The presence of post-traumatic stress disorder was very prevalent among adolescents four years after the Yushu earthquake. Effective mental health services should be developed to facilitate postdisaster recovery for bereaved adolescents at high risk for post-traumatic stress disorder. The findings in this study improve our understanding of post-traumatic stress disorder and related risk factors in bereaved adolescents in non-Western communities, providing useful information for

compared with exposed-SD animals. Intentional prevention of sleep in the early aftermath of stress exposure may well be beneficial in attenuating traumatic stress-related sequelae. Post-exposure SD may disrupt the consolidation of aversive or fearful memories by facilitating correctly timed interactions between glucocorticoid and adrenergic systems. PMID:22713910

Traumatic brain injury

There is an increasing incidence of military traumatic brain injury (TBI), and similar injuries are seen in civilians in war zones or terrorist incidents. Indeed, blast-induced mild TBI has been referred to as the signature injury of the conflicts in Iraq and Afghanistan. Assessment involves schemes that are common in civilcian practice but, in common with civilian TBI, takes little account of information available from modern imaging (particularly diffusion tensor magnetic resonance imaging) and emerging biomarkers. The efficient logistics of clinical care delivery in the field may have a role in optimizing outcome. Clinical care has much in common with civilian TBI, but intracranial pressure monitoring is not always available, and protocols need to be modified to take account of this. In addition, severe early oedema has led to increasing use of decompressive craniectomy, and blast TBI may be associated with a higher incidence of vasospasm and pseudoaneurysm formation. Visual and/or auditory deficits are common, and there is a significant risk of post-traumatic epilepsy. TBI is rarely an isolated finding in this setting, and persistent post-concussive symptoms are commonly associated with post-traumatic stress disorder and chronic pain, a constellation of findings that has been called the polytrauma clinical triad.

Patients with traumatic epidural haematoma, undergoing the prompt and correct treatment, usually have favourable outcomes. However, secondary cerebral infarction may be life-threatening condition, as it is difficult to be identified before neurological impairment occurs. To evaluate the clinical data of patients with traumatic EDH and assess potential risk factors for post-operative cerebral infarction. The clinical data of patients with traumatic EDH were collected and analysed retrospectively. The univariate analysis revealed 10 potential risk factors (the haematoma location, volume, the largest thickness and mid-line shift, basal cisterns compression, traumatic subarachnoid haemorrhage, pupil dilatation, pre-operative Glasgow Coma Scale score, ∆GCS and intraoperative brain pressure) for cerebral infarction with statistically significant difference. Of these factors, haematoma volume and basal cistern compression turned out to be the most significant risk factors through final multivariate logistic regression analysis. The findings of this study can provide predictive factors for development of cerebral infarction and information for clinical decision-making and future studies.

Research on emotional disclosure should test the effects of different disclosure methods and whether symptoms are affected differently than post-traumatic growth. We randomized 214 participants with unresolved stressful experiences to four disclosure conditions (written, private spoken, talking to a passive listener, talking to an active facilitator) or two control conditions. All groups had one 30-minute session. After 6 weeks, disclosure groups reported more post-traumatic growth than controls, and disclosure conditions were similar in this effect. All groups decreased in stress symptoms (intrusions, avoidance, psychological and physical symptoms), but disclosure did not differ from control. We conclude that 30 minutes of disclosure leads to post-traumatic growth but not necessarily symptom reduction, and various disclosure methods have similar effects. Research on the effects of disclosure should focus on the benefits of growth as well as symptom reduction. © 2010 Wiley Periodicals, Inc.

The Dissociative Subtype of Post-traumatic Stress Disorder: Research Update on Clinical and Neurobiological Features.

PubMed

van Huijstee, Jytte; Vermetten, Eric

2017-10-21

Recently, a dissociative subtype of post-traumatic stress disorder (PTSD) has been included in the DSM-5. This review focuses on the clinical and neurobiological features that distinguish the dissociative subtype of PTSD from non-dissociative PTSD. Clinically, the dissociative subtype of PTSD is associated with high PTSD severity, predominance of derealization and depersonalization symptoms, a more significant history of early life trauma, and higher levels of comorbid psychiatric disorders. Furthermore, PTSD patients with dissociative symptoms exhibit different psychophysiological and neural responses to the recall of traumatic memories. While individuals with non-dissociative PTSD exhibit an increased heart rate, decreased activation of prefrontal regions, and increased activation of the amygdala in response to traumatic reminders, individuals with the dissociative subtype of PTSD show an opposite pattern. It has been proposed that dissociation is a regulatory strategy to restrain extreme arousal in PTSD through hyperinhibition of limbic regions. In this research update, promises and pitfalls in current research studies on the dissociative subtype of PTSD are listed. Inclusion of the dissociative subtype of PTSD in the DSM-5 stimulates research on the prevalence, symptomatology, and neurobiology of the dissociative subtype of PTSD and poses a challenge to improve treatment outcome in PTSD patients with dissociative symptoms.

Post Traumatic Stress Disorder (PTSD) is still a diagnosis which is frequently missed even by psychiatric professionals. Each doctor needs to maintain a high level of awareness that patients may have experienced trauma; that PTSD can often occur for a variety of common symptoms; and that it may also be at the root of a persisting treatment-resistant depressive or anxiety state. This case demonstrates that occupational accidents may result in this condition.

Introduction Cognitive theories of psychopathology have generally proposed that early experiences of childhood abuse and neglect may result in the development of early maladaptive self-schemas. Maladaptive core schemas are central in the development and maintenance of psychological symptoms in a schema-focused approach. Psychosocial dysfunction in individuals with psychological problems has been consistently found to be associated with symptom severity. However, till date, linkages between psychosocial functioning, early traumatic experiences and core schemas have received little attention. The aim of the present study was to explore the relations among maladaptive interpersonal styles, negative experiences in childhood and core self-schemas in non-clinical adults. Methods A total of 300 adults (58% women) participated in the study. The participants completed a socio-demographic questionnaire, Young Schema Questionnaire, Childhood Trauma Questionnaire and Interpersonal Style Scale. Results Hierarchical regression analyses revealed that the Disconnection and Rejection and Impaired Limits schema domains were significant antecedents of maladaptive interpersonal styles after controlling for demographic characteristics and childhood abuse and neglect. Associations of child sexual abuse with Emotionally Avoidant, Manipulative and Abusive interpersonal styles were mediated by early maladaptive schemas. Early maladaptive schemas mediated the relations of emotional abuse with Emotionally Avoidant and Avoidant interpersonal styles as well as the relations of physical abuse with Avoidant and Abusive interpersonal styles. Conclusion Interpersonal styles in adulthood are significantly associated with childhood traumatic experiences. Significant relations between early traumatic experiences and maladaptive interpersonal styles are mediated by early maladaptive schemas. PMID:28360715

As a part of an ongoing clinical study of refugees with post traumatic stress disorder (PTSD), the primary objective of the current study was to examine and describe the distribution of adult attachment patterns as assessed by the Adult Attachment Interview (AAI) in Arabic-speaking refugees. A total of 43 adult male and female refugees with Iraqi and Palestinian backgrounds completed the AAI. Sixty-seven percent of the sample was classified as Unresolved with respect to loss or trauma and a substantial proportion of insecure attachment representations (14% Secure-Autonomous, 39% Dismissing, 42% Preoccupied, 5% Cannot Classify) was found, in addition to high intake levels of post traumatic stress symptoms and comorbidity. Findings are compared with AAI studies of other PTSD or trauma samples, and the paper elaborates upon the methodological challenges in administering the AAI in a context of simultaneous translation.

Late seizures after intracerebral haemorrhage occur after the initial acute haemorrhagic insult subsides, and represent one of its most feared long-term sequelae. Both susceptibility to late seizures and their functional impact remain poorly characterized. We sought to: (i) compare patients with new-onset late seizures (i.e. delayed seizures), with those who experienced a recurrent late seizure following an immediately post-haemorrhagic seizure; and (ii) investigate the effect of late seizures on long-term functional performance after intracerebral haemorrhage. We performed prospective longitudinal follow-up of consecutive intracerebral haemorrhage survivors presenting to a single tertiary care centre. We tested for association with seizures the following neuroimaging and genetic markers of cerebral small vessel disease: APOE variants ε2/ε4, computer tomography-defined white matter disease, magnetic resonance imaging-defined white matter hyperintensities volume and cerebral microbleeds. Cognitive performance was measured using the Modified Telephone Interview for Cognitive Status, and functional performance using structured questionnaires obtained every 6 months. We performed time-to-event analysis using separate Cox models for risk to develop delayed and recurrent seizures, as well as for functional decline risk (mortality, incident dementia, and loss of functional independence) after intracerebral haemorrhage. A total of 872 survivors of intracerebral haemorrhage were enrolled and followed for a median of 3.9 years. Early seizure developed in 86 patients, 42 of whom went on to experience recurrent seizures. Admission Glasgow Coma Scale, increasing haematoma volume and cortical involvement were associated with recurrent seizure risk (all P < 0.01). Recurrent seizures were not associated with long-term functional outcome (P = 0.67). Delayed seizures occurred in 37 patients, corresponding to an estimated incidence of 0.8% per year (95% confidence interval 0.5–1

Post-traumatic stress disorder (PTSD) is a condition associated with traumatic brain injury (TBI). While the importance of PTSD and TBI among military personnel is widely recognized, there is less awareness of PTSD associated with civilian TBI. We examined the incidence and factors associated with PTSD 6 months post-injury in a civilian emergency department population using measures from the National Institute of Neurological Disorders and Stroke TBI Common Data Elements Outcome Battery. Participants with mild TBI (mTBI) from the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot study with complete 6-month outcome batteries (n = 280) were analyzed. Screening for PTSD symptoms was conducted using the PTSD Checklist-Civilian Version. Descriptive measures are summarized and predictors for PTSD were examined using logistic regression. Incidence of screening positive for PTSD was 26.8% at 6 months following mTBI. Screening positive for PTSD was significantly associated with concurrent functional disability, post-concussive and psychiatric symptomatology, decreased satisfaction with life, and decreased performance in visual processing and mental flexibility. Multi-variable regression showed injury mechanism of assault (odds ratio [OR] 3.59; 95% confidence interval [CI] 1.69-7.63; p = 0.001) and prior psychiatric history (OR 2.56; 95% CI 1.42-4.61; p = 0.002) remained significant predictors of screening positive for PTSD, while education (per year OR 0.88; 95% CI 0.79-0.98; p = 0.021) was associated with decreased odds of PTSD. Standardized data collection and review of pre-injury education, psychiatric history, and injury mechanism during initial hospital presentation can aid in identifying patients with mTBI at risk for developing PTSD symptoms who may benefit from closer follow-up after initial injury care.

Facilitating post traumatic growth

2004-01-01

Background Whilst negative responses to traumatic injury have been well documented in the literature, there is a small but growing body of work that identifies posttraumatic growth as a salient feature of this experience. We contribute to this discourse by reporting on the experiences of 13 individuals who were traumatically injured, had undergone extensive rehabilitation and were discharged from formal care. All participants were injured through involvement in a motor vehicle accident, with the exception of one, who was injured through falling off the roof of a house. Methods In this qualitative study, we used an audio-taped in-depth interview with each participant as the means of data collection. Interviews were transcribed verbatim and analysed thematically to determine the participants' unique perspectives on the experience of recovery from traumatic injury. In reporting the findings, all participants' were given a pseudonym to assure their anonymity. Results Most participants indicated that their involvement in a traumatic occurrence was a springboard for growth that enabled them to develop new perspectives on life and living. Conclusion There are a number of contributions that health providers may make to the recovery of individuals who have been traumatically injured to assist them to develop new views of vulnerability and strength, make changes in relationships, and facilitate philosophical, physical and spiritual growth.

Management of post-traumatic headaches in children and adolescents.

PubMed

Kacperski, Joanne; Arthur, Todd

2016-01-01

Traumatic brain injuries (TBI) occur in an estimated 475,000 children aged 0-14 each year. Worldwide, mild traumatic brain injuries (mTBI) represent around 75-90% of all hospital admissions for TBI. mTBI are a common occurrence in children and adolescents, particularly in those involved in athletic activities. An estimated 1.6-3.8 million sports-related TBIs occur each year, including those for which no medical care is sought. Headache is a common occurrence following TBI, reported in as many as 86% of high school and college athletes who have suffered from head trauma. As most clinicians who manage concussion and post-traumatic headaches (PTHs) can attest, these headaches may be difficult to treat. There are currently no established guidelines for the treatment of PTHs, especially when persistent, and practices can vary widely from one clinician to the next. Making medical management more challenging, there are currently no randomized controlled trials evaluating the efficacy of therapies for PTHs in children and adolescents. © 2015 American Headache Society.

Objective To determine the frequency of mutations in CDKL5 in both male and female patients with infantile spasms or early onset epilepsy of unknown cause, and to consider whether the breadth of the reported phenotype would be extended by studying a different patient group. Methods Two groups of patients were investigated for CDKL5 mutations. Group 1 comprised 73 patients (57 female, 16 male) referred to Cardiff for CDKL5 analysis, of whom 49 (42 female, 7 male) had epileptic seizure onset in the first six months of life. Group 2 comprised 26 patients (11 female, 15 male) with infantile spasms previously recruited to a clinical trial, the UK Infantile Spasms Study. Where a likely pathogenic mutation was identified, further clinical data were reviewed. Results Seven likely pathogenic mutations were found among female patients from group 1 with epileptic seizure onset in the first six months of life, accounting for seven of the 42 in this group (17%). No mutations other than the already published mutation were found in female patients from group 2, or in any male patient from either study group. All patients with mutations had early signs of developmental delay and most had made little developmental progress. Further clinical information was available for six patients: autistic features and tactile hypersensitivity were common but only one had suggestive Rett‐like features. All had a severe epileptic seizure disorder, all but one of whom had myoclonic jerks. The EEG showed focal or generalised changes and in those with infantile spasms, hypsarrhythmia. Slow frequencies were seen frequently with a frontal or fronto‐temporal predominance and high amplitudes. Conclusions The spectrum of the epileptic seizure disorder, and associated EEG changes, in those with CDKL5 mutations is broader than previously reported. CDKL5 mutations are a significant cause of infantile spasms and early epileptic seizures in female patients, and of a later intractable seizure disorder

Longitudinal changes of telomere length and epigenetic age related to traumatic stress and post-traumatic stress disorder.

Several studies have reported an association between traumatic stress and telomere length suggesting that traumatic stress has an impact on ageing at the cellular level. A newly derived tool provides an additional means to investigate cellular ageing by estimating epigenetic age based on DNA methylation profiles. We therefore hypothesise that in a longitudinal study of traumatic stress both indicators of cellular ageing will show increased ageing. We expect that particularly in individuals that developed symptoms of post-traumatic stress disorder (PTSD) increases in these ageing parameters would stand out. From an existing longitudinal cohort study, ninety-six male soldiers were selected based on trauma exposure and the presence of symptoms of PTSD. All military personnel were deployed in a combat zone in Afghanistan and assessed before and 6 months after deployment. The Self-Rating Inventory for PTSD was used to measure the presence of PTSD symptoms, while exposure to combat trauma during deployment was measured with a 19-item deployment experiences checklist. These groups did not differ for age, gender, alcohol consumption, cigarette smoking, military rank, length, weight, or medication use. In DNA from whole blood telomere length was measured and DNA methylation levels were assessed using the Illumina 450K DNA methylation arrays. Epigenetic ageing was estimated using the DNAm age estimator procedure. The association of trauma with telomere length was in the expected direction but not significant (B=-10.2, p=0.52). However, contrary to our expectations, development of PTSD symptoms was associated with the reverse process, telomere lengthening (B=1.91, p=0.018). In concordance, trauma significantly accelerated epigenetic ageing (B=1.97, p=0.032) and similar to the findings in telomeres, development of PTSD symptoms was inversely associated with epigenetic ageing (B=-0.10, p=0.044). Blood cell count, medication and premorbid early life trauma exposure did not

Chronic post-traumatic headache: clinical findings and possible mechanisms

Defrin, Ruth

2014-01-01

Chronic post-traumatic headache (CPTHA), the most frequent complaint after traumatic brain injury (TBI), dramatically affects quality of life and function. Despite its high prevalence and persistence, the mechanism of CPTHA is poorly understood. This literature review aimed to analyze the results of studies assessing the characteristics and sensory profile of CPTHA in order to shed light on its possible underlying mechanisms. The search for English language articles published between 1960 and 2013 was conducted in MEDLINE, CINAHL, and PubMed. Studies assessing clinical features of headache after TBI as well as studies conducting quantitative somatosensory testing (QST) in individuals with CPTHA and in individuals suffering from other types of pain were included. Studies on animal models of pain following damage to peripheral tissues and to the peripheral and central nervous system were also included. The clinical features of CPTHA resembled those of primary headache, especially tension-type and migraine headache. Positive and negative signs were prevalent among individuals with CPTHA, in both the head and in other body regions, suggesting the presence of local (cranial) mechanical hypersensitivity, together with generalized thermal hypoesthesia and hypoalgesia. Evidence of dysfunctional pain modulation was also observed. Chronic post-traumatic headache can result from damage to intra- and pericranial tissues that caused chronic sensitization of these tissues. Alternatively, although not mutually exclusive, CPTHA might possibly be a form of central pain due to damage to brain structures involved in pain processing. These, other possibilities, as well as risk factors for CPTHA are discussed at length. PMID:24976746

Maternal mental health has been largely neglected in the literature. Women, however, may be vulnerable to developing post-traumatic stress symptoms or post-traumatic stress disorder (PTSD), following traumatic birth. In turn, this may affect their capacity for child rearing and ability to form a secure bond with their baby and impact on the wider family. Trauma-focused psychological therapies (TFPT) are widely regarded as effective and acceptable interventions for PTSD in general and clinical populations. Relatively little is known about the effectiveness of TFPT for women postpartum who have post-traumatic stress symptoms. We will conduct a review to assess the effectiveness of TFPT, compared with usual postpartum care, as a treatment for post-traumatic stress symptoms or PTSD for women following traumatic birth. Using a priori search criteria, we will search for randomised controlled trials (RCT) in four databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO and OpenGrey. We will use search terms that relate to the population, TFPT and comparators. Screening of search results and data extraction will be undertaken by two reviewers, independently. Risk of bias will be assessed in RCTs which meet the review criteria. Data will be analysed using the following methods, as appropriate: narrative synthesis; meta-analysis; subgroup analysis and meta-regression. As this work comprises a synthesis of existing studies, ethical approvals are not required. Results will be disseminated at conferences and in publications.

This is an updated version of the Cochrane Review previously published in Issue 3, 2015.The incidence of seizures following supratentorial craniotomy for non-traumatic pathology has been estimated to be between 15% to 20%; however, the risk of experiencing a seizure appears to vary from 3% to 92% over a five-year period. Postoperative seizures can precipitate the development of epilepsy; seizures are most likely to occur within the first month of cranial surgery. The use of antiepileptic drugs (AEDs) administered pre- or postoperatively to prevent seizures following cranial surgery has been investigated in a number of randomised controlled trials (RCTs). To determine the efficacy and safety of AEDs when used prophylactically in people undergoing craniotomy and to examine which AEDs are most effective. For the latest update we searched the following databases on 26 June 2017: Cochrane Epilepsy Group Specialized Register, the CENTRAL, MEDLINE, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP). We did not apply any language restrictions. We included RCTs of people with no history of epilepsy who were undergoing craniotomy for either therapeutic or diagnostic reasons. We included trials with adequate randomisation methods and concealment; these could either be blinded or unblinded parallel trials. We did not stipulate a minimum treatment period, and we included trials using active drugs or placebo as a control group. Three review authors (JW, JG, YD) independently selected trials for inclusion and performed data extraction and risk of bias assessments. We resolved any disagreements through discussion. Outcomes investigated included the number of participants experiencing seizures (early (occurring within first week following craniotomy), and late (occurring after first week following craniotomy)), the number of deaths and the number of people experiencing disability and adverse effects. Due to the heterogeneous nature of the trials

to explore the possibility of using eye movement desensitisation and reprocessing (EMDR) to treat women who have experienced post-traumatic stress after childbirth. the pilot study consisted of a 'before and after' treatment design combined with follow-up measurements 1-3 years after EMDR treatment. Quantitative data from questionnaires (Traumatic Event Scale [TES]) were collected. In addition, qualitative data from individual interviews with the participants were collected as well as data from the psychotherapist's treatment notes of the EMDR treatment sessions. the north of Sweden. four women with post-traumatic stress disorder (PTSD) after childbirth (one pregnant and three non-pregnant). all participants reported reduction of post-traumatic stress after treatment. After 1-3 years, the beneficial effects of EMDR treatment remained for three of the four women. Symptoms of intrusive thoughts and avoidance seemed most sensitive for treatment. EMDR might be a useful tool in the treatment of non-pregnant women severely traumatised by childbirth; however, further research is required.

Approximately 50-65% of Australians are exposed to a traumatic event during their lifetime. Approximately 250 000 Australians suffer from post-traumatic stress disorder (PTSD) at any given time, making it one of the most common anxiety disorders. In May 2007, the Australian guidelines for the treatment of adults with acute stress disorder and posttraumatic stress disorder was published. In order to facilitate translation of evidence regarding PTSD into busy clinical practice, and particularly for general practitioners, a more succinct version of the guidelines has been developed. This article describes a brief algorithm based on the Australian guidelines and outlines key recommendations. General practitioners are often the first point of contact with the health care system for someone who has experienced a traumatic event. Patients experiencing trauma within the past 2 weeks require psychological first aid, and monitoring and assessment for the development of acute stress disorder and symptoms of PTSD. If the patient wishes to talk about the event with you, support them in doing so. However, it is important not to push those who prefer not to talk about the event. Trauma focused psychological treatment is the first line of treatment for PTSD, although antidepressant medication may have an adjuvant role in some patients or in those with comorbidities.

To determine the impact of earlier urethral interventions on the outcomes of anastomotic urethroplasty in post-traumatic stricture urethra. From October 1995 to March 2008, a total of 58 patients with post-traumatic posterior urethral stricture underwent anastomotic urethroplasty. Eighteen patients had earlier undergone urethral intervention in the form of urethrotomy (3), endoscopic realignment (7), or open urethroplasty (8). Success was defined as no obstructive urinary symptoms, maximum urine flow rate > or = 15 mL/s, normal urethral imaging and/or urethroscopy, and no need of any intervention in the follow-up period. Patients who met the above objective criteria after needing 1 urethrotomy following urethroplasty were defined to have satisfactory outcome and were included in satisfactory result rate along with patients who had a successful outcome. Results were analyzed using unpaired t test, chi-square test, binary logistic regression, Kaplan-Meier curves, and log rank test. Previous interventions in the form of endoscopic realignment or urethroplasty have significant adverse effect on the success rate of subsequent anastomotic urethroplasty for post-traumatic posterior urethral strictures (P <.05). Previous intervention in the form of visual internal urethrotomies (up to 2 times) did not affect the outcome of subsequent anastomotic urethroplasty. Length of stricture and age of patient did not predict the outcome in traumatic posterior urethral strictures in logistic regression analysis. Previous failed railroading or urethroplasty significantly decrease the success of subsequent anastomotic urethroplasty. Hence, a primary realignment or urethroplasty should be avoided in suboptimal conditions and the cases of post-traumatic urethral stricture should be referred to centers with such expertise. 2010 Elsevier Inc.

Subchondral bone is thought to play a significant role in the initiation and progression of the post-traumatic osteoarthritis. The goal of this study was to document changes in tibial and femoral subchondral bone that occur as a result of two lapine models of anterior cruciate ligament injury, a modified ACL transection model and a closed-joint traumatic compressive impact model. Twelve weeks post-injury bones were scanned via micro-computed tomography. The subchondral bone of injured limbs from both models showed decreases in bone volume and bone mineral density. Surgical transection animals showed significant bone changes primarily in the medial hemijoint of femurs and tibias, while significant changes were noted in both the medial and lateral hemijoints of both bones for traumatic impact animals. It is believed that subchondral bone changes in the medial hemijoint were likely caused by compromised soft tissue structures seen in both models. Subchondral bone changes in the lateral hemijoint of traumatic impact animals are thought to be due to transmission of the compressive impact force through the joint. The joint-wide bone changes shown in the traumatic impact model were similar to clinical findings from studies investigating the progression of osteoarthritis in humans. PMID:26147652

Background Most studies of post-traumatic stress disorder (PTSD) in low- and middle-income countries (LMICs) have focused on ‘high-risk’ populations defined by exposure to trauma. Aims To estimate the prevalence of post-traumatic stress disorder (PTSD) in a LMIC, the conditional probability of PTSD given a traumatic event and the strength of associations between traumatic events and other psychiatric disorders. Method Our sample contained a mix of 3995 twins and 2019 non-twins. We asked participants about nine different traumatic exposures, including the category ‘other’, but excluding sexual trauma. Results Traumatic events were reported by 36.3% of participants and lifetime PTSD was present in 2.0%. Prevalence of non-PTSD lifetime diagnosis was 19.1%. Of people who had experienced three or more traumatic events, 13.3% had lifetime PTSD and 40.4% had a non-PTSD psychiatric diagnosis. Conclusions Despite high rates of exposure to trauma, this population had lower rates of PTSD than high-income populations, although the prevalence might have been slightly affected by the exclusion of sexual trauma. There are high rates of non-PTSD diagnoses associated with trauma exposure that could be considered in interventions for trauma-exposed populations. Our findings suggest that there is no unique relationship between traumatic experiences and the specific symptomatology of PTSD. PMID:25257062

Perspectives on Creating Clinically Relevant Blast Models for Mild Traumatic Brain Injury and Post Traumatic Stress Disorder Symptoms

2012-01-01

Military personnel are returning from Iraq and Afghanistan and reporting non-specific physical (somatic), behavioral, psychological, and cognitive symptoms. Many of these symptoms are frequently associated with mild traumatic brain injury (mTBI) and/or post traumatic stress disorder (PTSD). Despite significant attention and advances in assessment and intervention for these two conditions, challenges persist. To address this, clinically relevant blast models are essential in the full characterization of this type of injury, as well as in the testing and identification of potential treatment strategies. In this publication, existing diagnostic challenges and current treatment practices for mTBI and/or PTSD will be summarized, along with suggestions regarding how what has been learned from existing models of PTSD and traditional mechanism (e.g., non-blast) traumatic brain injury can be used to facilitate the development of clinically relevant blast models.

Political violence is known to cause psychological distress. There is a large body of empirical studies drawing correlations between war trauma, torture, and post-traumatic stress disorder (PTSD). However, there are few studies on the effects of war-related trauma among Syrian refugees after events following the 'Arab Spring' uprisings between 2010 and 2012. This study examines the association of PTSD symptoms with torture and other traumatic events among Syrian Kurdish refugees living in Kurdistan Region, Iraq. The experiences and PTSD symptoms among 91 Syrian Kurdish refugees in the Arbat camp in the Sulaymaniyah Governorate of the Kurdistan Region of Iraq were assessed using the Harvard Trauma Questionnaire, sections I, IV, and V. Results showed that the estimated levels of PTSD symptoms were high: between 35 and 38%. There were no significant gender differences in the occurrence of PTSD symptoms. However, men reported more general traumatic experiences than women. There were significant positive correlations between PTSD symptoms with traumatic events and torture ( r = 0.500, r = 0.366, respectively). Examining the mental health impact of torture and other traumatic events among refugees has possible implications for organizations managing rehabilitation programs for individuals who have been exposed to traumatic events.

The diversity of methodological approaches and lack of pathogenetically reasonable tactics for patients with combined ocular injuries became the basis for the development and systematization of surgical rehabilitation stages of patients, in whom post-traumatic cataract is combined with post-traumatic aniridia and corneal scarring. to construct a visual rehabilitation approach to patients with post-traumatic defects of the anterior eye segment following optical-reconstructive surgery that involved implantation of an iris-lens diaphragm (ILD). We have analyzed 80 reconstructive cases with ILD implantation in patients with post-traumatic aniridia and corneal damage. These patients constituted the first study group (Group 1). We have also investigated 58 eyes with residual ametropy and stable visual function 1 year after ILD implantation before and after conducting a laser keratorefractive surgery. These patients were assigned to the second study group (Group 2). Rehabilitation approach to patients after anterior segment injuries that has been proposed allows to achieve high clinical and functional results and reduce the risk of intra- and postoperative complications. The proposed approach to patients after optical-reconstructive surgery with iris-lens diaphragm implantation followed by keratorefractive surgery is an effective method of visual rehabilitation of anterior eye segment post-traumatic defects.

Do South African former detainees experience post-traumatic stress? Circumventing the demand characteristics of psychological assessment.

Most research on persons subjected to physical or psychological torture for political reasons has framed this experience as traumatic, with the sequelae approximating the diagnostic criteria of post-traumatic stress disorder (PTSD). Yet, critiques of the trauma model have called attention to the fact that PTSD represents a Western conceptualization of the concerns of persons who have survived stressful experiences. In order to determine whether symptoms of traumatization are salient psychiatric phenomena for South African former detainees, semi-structured qualitative interviews were conducted with 20 respondents who were detained and tortured for political reasons during the apartheid era. Interviews were transcribed and analysed for thematic content using a grounded theory approach. Results showed that although the main concerns expressed were unrelated to traumatization, participants also indicated that they experienced symptoms of post-traumatic stress. These data suggest that although too great a focus on traumatic responses may be misplaced, it remains important to consider the possibility that former detainees may exhibit symptoms of this nature. Consequently, critiques of the trauma discourse as a Western phenomenon need to be tempered with evidence of the lived reality of psychological sequelae experienced by this population.

The objective of this study was to explore whether ketamine prevents or exacerbates acute or post-traumatic stress disorders in military trauma patients. We conducted a retrospective study of a database from the French Military Health Service, including all soldiers surviving a war injury in Afghanistan (2010-2012). The diagnosis of post-traumatic stress disorder was made by a psychiatrist and patients were analysed according to the presence or absence of this condition. Analysis included the following covariables: age; sex; acute stress disorder; blast injury; associated fatality; brain injury; traumatic amputation; Glasgow coma scale; injury severity score; administered drugs; number of surgical procedures; physical, neurosensory or aesthetic sequelae; and the development chronic pain. Covariables related to post-traumatic and acute stress disorders with a p ≤ 0.10 were included in a multivariable logistic regression model. The data from 450 soldiers were identified; 399 survived, of which 274 were analysed. Among these, 98 (36%) suffered from post-traumatic stress disorder and 89 (32%) had received ketamine. Fifty-four patients (55%) in the post-traumatic stress disorder group received ketamine vs. 35 (20%) in the no PTSD group (p < 0.001). The 89 injured soldiers who received ketamine had a median (IQR [range]) injury severity score of 5 (3-13 [1-26]) vs. 3 (2-4 [1-6] in the 185 patients who did not (p < 0.001). At multivariable analysis, only acute stress disorder and total number of surgical procedures were independently associated with the development of post-traumatic stress disorder. In this retrospective study, ketamine administration was not a risk factor for the development of post-traumatic stress disorder in the military trauma setting. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

The current study was to examine the relationship among depressive symptoms, post-traumatic stress symptoms, emotion regulatory self-efficacy and suicide risk. A cross-sectional survey was conducted among 3257 graduate students from a medical college of China. Lifetime prevalence of suicidal ideation, plan and attempt were 25.7%, 1.6%, 1.1%, respectively, with one-year suicidal ideation showing at 6.3%. Structural equation modeling was employed to examine the relative contribution of depressive symptoms, post-traumatic stress symptoms and emotion regulatory self-efficacy on suicide risk. Structural equation model had a highly satisfactory fit [χ 2  = 7.782, df = 4, p = 0.096; RMSEA = 0.021; CFI = 0.992; GFI = 0.997]. Post-traumatic stress symptoms had a direct effect and an indirect effect on suicide risk via emotion regulatory self-efficacy. Depressive symptoms also had a direct effect and an indirect effect on suicide risk via emotion regulatory self-efficacy. The depressive and post-traumatic stress symptoms increased the risk of suicide risk, but the variable of emotion regulatory self-efficacy would be served as a buffering factor, decreasing the risk of suicide. The interaction term of depressive symptoms and post-traumatic stress symptoms had a direct effect on suicide risk. A significant interactive effect of depressive and post-traumatic stress symptoms on suicide risk was found. Copyright © 2018 Elsevier B.V. All rights reserved.

Post-traumatic stress disorder following disasters: a systematic review

2016-01-01

Background Disasters are traumatic events that may result in a wide range of mental and physical health consequences. Post-traumatic stress disorder (PTSD) is probably the most commonly studied post-disaster psychiatric disorder. This review aimed to systematically assess the evidence about PTSD following exposure to disasters. Method A systematic search was performed. Eligible studies for this review included reports based on the DSM criteria of PTSD symptoms. The time-frame for inclusion of reports in this review is from 1980 (when PTSD was first introduced in DSM-III) and February 2007 when the literature search for this examination was terminated. Results We identified 284 reports of PTSD following disasters published in peer-reviewed journals since 1980. We categorized them according to the following classification: (1) human-made disasters (n=90), (2) technological disasters (n=65), and (3) natural disasters (n=116). Since some studies reported on findings from mixed samples (e.g. survivors of flooding and chemical contamination) we grouped these studies together (n=13). Conclusions The body of research conducted after disasters in the past three decades suggests that the burden of PTSD among persons exposed to disasters is substantial. Post-disaster PTSD is associated with a range of correlates including sociodemographic and background factors, event exposure characteristics, social support factors and personality traits. Relatively few studies have employed longitudinal assessments enabling documentation of the course of PTSD. Methodological limitations and future directions for research in this field are discussed.

To date, studies of biological risk factors have revealed inconsistent relationships with subsequent post-traumatic stress disorder (PTSD). The inconsistent signal may reflect the use of data analytic tools that are ill equipped for modeling the complex interactions between biological and environmental factors that underlay post-traumatic psychopathology. Further, using symptom-based diagnostic status as the group outcome overlooks the inherent heterogeneity of PTSD, potentially contributing to failures to replicate. To examine the potential yield of novel analytic tools, we reanalyzed data from a large longitudinal study of individuals identified following trauma in the general emergency room (ER) that failed to find a linear association between cortisol response to traumatic events and subsequent PTSD. First, latent growth mixture modeling empirically identified trajectories of post-traumatic symptoms, which then were used as the study outcome. Next, support vector machines with feature selection identified sets of features with stable predictive accuracy and built robust classifiers of trajectory membership (area under the receiver operator characteristic curve (AUC)=0.82 (95% confidence interval (CI)=0.80–0.85)) that combined clinical, neuroendocrine, psychophysiological and demographic information. Finally, graph induction algorithms revealed a unique path from childhood trauma via lower cortisol during ER admission, to non-remitting PTSD. Traditional general linear modeling methods then confirmed the newly revealed association, thereby delineating a specific target population for early endocrine interventions. Advanced computational approaches offer innovative ways for uncovering clinically significant, non-shared biological signals in heterogeneous samples. PMID:28323285

Spinal meningiomas usually present with slowly progressive symptoms of cord and root compression, while a sudden clinical onset is very rare. A 35-year-old previously symptom-free woman presented sudden right sciatica and weakness of her right leg following a fall with impact to her left foot. A neurological examination showed paresis of the right quadriceps, tibial and sural muscles, increased bilateral knee and ankle reflexes and positive Babinski sign. Magnetic resonance imaging (MRI) revealed the presence of a spinal T11 meningioma in the left postero-lateral compartment of the spinal canal; at this level, the spinal cord was displaced to the contralateral side with the conus in the normal position. At surgery, a meningioma with dural attachment of the left postero-lateral dural surface was removed. The intervention resulted in rapid remission of both pain and neurological deficits. Spinal meningiomas may exceptionally present with sudden pain and neurological deficits as result of tumour bleeding or post-traumatic injury of the already compressed nervous structures, both in normal patients and in those with conus displacement or tethered cord. In this case, the traumatic impact of the left foot was transmitted to the spine, resulting in stretching of the already compressed cord and of the contralateral lombosacral roots. This case suggests that low thoracic cord compression should be suspected in patients with post-traumatic radicular leg pain with normal lumbar spine MRI. © The Author(s) 2016.

Seizure susceptibility of neuropeptide-Y null mutant mice in amygdala kindling and chemical-induced seizure models.

Neuropeptide Y (NPY) administered exogenously is anticonvulsant, and, NPY null mutant mice are more susceptible to kainate-induced seizures. In order to better understand the potential role of NPY in epileptogenesis, the present studies investigated the development of amygdala kindling, post-kindling seizure thresholds, and anticonvulsant effects of carbamazepine and levetiracetam in 129S6/SvEv NPY(+/+) and NPY(-/-) mice. In addition, susceptibility to pilocarpine- and kainate-induced seizures was compared in NPY(+/+) and (-/-) mice. The rate of amygdala kindling development did not differ in the NPY(-/-) and NPY(+/+) mice either when kindling stimuli were presented once daily for at least 20 days, or, 12 times daily for 2 days. However, during kindling development, the NPY(-/-) mice had higher seizure severity scores and longer afterdischarge durations than the NPY(+/+) mice. Post-kindling, the NPY(-/-) mice had markedly lower afterdischarge thresholds and longer afterdischarge durations than NPY (+/+) mice. Carbamazepine and levetiracetam increased the seizure thresholds of both NPY (-/-) and (+/+) mice. In addition, NPY (-/-) mice had lower thresholds for both kainate- and pilocarpine-induced seizures. The present results in amygdala kindling and chemical seizure models suggest that NPY may play a more prominent role in determining seizure thresholds and severity of seizures than in events leading to epileptogenesis. In addition, a lack of NPY does not appear to confer drug-resistance in that carbamazepine and levetiracetam were anticonvulsant in both wild type (WT) and NPY null mutant mice.

Family Caregivers of Liver Transplant Recipients: Coping Strategies Associated With Different Levels of Post-traumatic Growth.

Analyze the influence of 2 variables (post-traumatic growth and time since liver transplantation) on coping strategies used by the transplant recipient's family members. In all, 218 family members who were their main caregivers of liver transplant recipients were selected. They were evaluated using the Posttraumatic Growth Inventory and the Brief COPE. A 3 × 3 factorial analysis of variance was used to analyze the influence that post-traumatic growth level (low, medium, and high) and time since transplantation (≤3.5 years, >3.5 to ≤9 years, and >9 years) exerted on caregiver coping strategies. No interactive effects between the two factors in the study were found. The only significant main effect was the influence of the post-traumatic growth factor on the following variables: instrumental support (P = .007), emotional support (P = .005), self-distraction (P = .006), positive reframing (P = .000), acceptance (P = .013), and religion (P = <.001). According to the most relevant effect sizes, low post-traumatic growth compared with medium growth was associated with less use of self-distraction (P = .006, d = -0.52, medium effect size), positive reframing (P = .001, d = -0.62, medium effect size), and religion (P = .000, d = -0.66, medium effect size), and in comparison with high growth, it was associated with less use of positive reframing (P = .002, d = -0.56, medium effect size) and religion (P = .000, d = 0.87, large effect size). Regardless of the time elapsed since the stressful life event (liver transplantation), family members with low post-traumatic growth usually use fewer coping strategies involving a positive, transcendent vision to deal with transplantation.

Previous studies have documented weaknesses in cognitive ability and early academic readiness in young children with traumatic brain injury (TBI). However, few of these studies have rigorously controlled for demographic characteristics, examined the effects of TBI severity on a wide range of skills, or explored moderating influences of environmental factors on outcomes. To meet these objectives, each of three groups of children with TBI (20 with severe, 64 with moderate, and 15 with mild) were compared with a group of 117 children with orthopedic injuries (OI group). The children were hospitalized for their injuries between 3 and 6 years of age and were assessed an average of 1½ months post injury. Analysis revealed generalized weaknesses in cognitive and school readiness skills in the severe TBI group and suggested less pervasive effects of moderate and mild TBI. Indices of TBI severity predicted outcomes within the TBI sample and environmental factors moderated the effects of TBI on some measures. The findings document adverse effects of TBI in early childhood on post-acute cognitive and school readiness skills and indicate that residual deficits are related to both injury severity and the family environment.

High risk of hypogonadism after traumatic brain injury: clinical implications.

PubMed

Agha, Amar; Thompson, Christopher J

2005-01-01

Several recent studies have convincingly documented a close association between traumatic brain injury (TBI) and pituitary dysfunction. Post-traumatic hypogonadism is very common in the acute post-TBI phase, though most cases recover within six to twelve months following trauma. The functional significance of early hypogonadism, which may reflect adaptation to acute illness, is not known. Hypogonadism persists, however, in 10-17% of long-term survivors. Sex steroid deficiency has implications beyond psychosexual function and fertility for survivors of TBI. Muscle weakness may impair functional recovery from trauma and osteoporosis may be exacerbated by immobility secondary to trauma. Identification and appropriate and timely management of post-traumatic hypogonadism is important in order to optimise patient recovery from head trauma, improve quality of life and avoid the long-term adverse consequences of untreated sex steroid deficiency.

To describe relationships between cumulative trauma, partner conflict and post-traumatic stress in African-American postpartum women. Cumulative trauma exposure estimates for women in the USA range from 51-69%. During pregnancy, most trauma research has focused on physical injury to the mother. Post-traumatic stress disorder (PTSD) is associated with trauma and more prevalent in African-American women than women of other groups. Knowledge about both the rate and impact of cumulative trauma on pregnancy may contribute to our understanding of women seeking prenatal care, and disparities in infant morbidity and mortality. This retrospective, correlational, cross-sectional study took place on postpartum units of two Detroit hospitals. Participants were 150 African-American women aged between 18-45 who had given birth. Mothers completed the Cumulative Trauma Scale, Conflict Tactics Scale, Clinician Administered Post-traumatic Stress Scale, Edinburgh Postnatal Depression Scale and a Demographic Data form. Descriptive statistics, correlations and multiple regressions were used for data analysis. All participants reported at least one traumatic event in their lifetime. Cumulative trauma and partner conflict predicted PTSD, with the trauma of a life-threatening event for a loved one reported by 60% of the sample. Nearly, one-fourth of the women screened were at risk for PTSD. Increased cumulative trauma, increased partner conflict and lower level of education were related to higher rates of PTSD symptoms. Both cumulative trauma and partner conflict in the past year predict PTSD. Reasoning was used most often for partner conflict resolution. The results of this study offer additional knowledge regarding relationships between cumulative trauma, partner conflict and PTSD in African-American women. Healthcare providers need to be sensitive to patient life-threatening events, personal failures, abuse and other types of trauma. Current evidence supports the need to assess for

Emergency medical service (EMS) personnel who work to provide emergency medical care at the scene and during transportation are exposed to various kinds of stressors and are particularly susceptible to developing stress-reactions. This study assesses symptoms of post-traumatic stress disorder and its predictors among the personnel of a selected EMS in Karachi, Pakistan. Data were gathered from 518 personnel working in an EMS setting from February to May 2014. Participants were screened for post-traumatic stress symptoms using the Impact of Event Scale-Revised (IES-R). Demographic and work-related characteristics, coping styles and the social support systems of the participants were assessed. Linear regression was used on the IES-R to identify predictors of post-traumatic stress symptoms. The mean score of the IES-R was 23.9 ± 12.1. EMS personnel with a dysfunctional coping style (β = 0.67 CI 0.39 - 0.95), anxiety, and depression (β = 0.64 CI 0.52 - 0.75) were more likely to have increased severity of post-traumatic stress symptoms. Age was found to have an inverse relationship with stress symptoms (β = -0.17 CI 0.33 - -0.023), indicating the susceptibility of younger EMS personnel to stress. The EMS personnel in this setting were found to have a moderate level of post-traumatic stress symptoms. The significant predictors of post-traumatic stress symptoms in this EMS population were age, coping style, and levels of anxiety and depression. These predicting factors can be a potential avenue for interventions to improve the mental health of these frontline workers.

Post-Traumatic Symptomatology and Compulsions as Potential Mediators of the Relation Between Child Sexual Abuse and Auditory Verbal Hallucinations.

PubMed

McCarthy-Jones, Simon

2018-05-01

Whilst evidence is mounting that childhood sexual abuse (CSA) can be a cause of auditory verbal hallucinations (AVH), it is unclear what factors mediate this relation. Recent evidence suggests that post-traumatic symptomatology may mediate the CSA-AVH relation in clinical populations, although this hypothesis has not yet been tested in the general population. There is also reason to believe that obsessive ideation could mediate the CSA-AVH relation. To test for evidence to falsify the hypotheses that post-traumatic symptomatology, obsessions, compulsions, anxiety and depression mediate the relation between CSA and AVH in a general population sample. Indirect effects of CSA on AVH via potential mediators were tested for, using a regression-based approach employing data from the 2007 Adult Psychiatric Morbidity Survey (n = 5788). After controlling for demographics, IQ and child physical abuse, it was found that CSA, IQ, post-traumatic symptomatology and compulsions predicted lifetime experience of AVH. Mediation analyses found significant indirect effects of CSA on AVH via post-traumatic symptomatology [odds ratio (OR): 1.11; 95% confidence interval (CI):1.00-1.29] and compulsions (OR: 1.10, 95% CI: 1.01-1.28). These findings offer further support for the hypothesis that post-traumatic symptomatology is a mediator of the CSA-AVH relation. Although no evidence was found for obsessional thoughts as a mediating variable, a potential mediating role for compulsions is theoretically intriguing. This study's findings reiterate the need to ask about experiences of childhood adversity and post-traumatic symptomology in people with AVH, as well as the likely therapeutic importance of trauma-informed and trauma-based interventions for this population.

The Sewol ferry disaster caused national shock and grief in Korea. The present study examined the prevalence and associated factors of post-traumatic stress disorder (PTSD) symptoms among the surviving students 20 months after that disaster. This study was conducted using a cross-sectional design and a sample of 57 students (29 boys and 28 girls) who survived the Sewol ferry disaster. Data were collected using a questionnaire, including instruments that assessed psychological status. A generalized linear model using a log link and Poisson distribution was performed to identify factors associated with PTSD symptoms. The results showed that 26.3% of participants were classified in the clinical group by the Child Report of Post-traumatic Symptoms score. Based on a generalized linear model, Poisson distribution, and log link analyses, PTSD symptoms were positively correlated with the number of exposed traumatic events, peers and social support, peri-traumatic dissociation and post-traumatic negative beliefs, and emotional difficulties. On the other hand, PTSD symptoms were negatively correlated with psychological well-being, family cohesion, post-traumatic social support, receiving care at a psychiatry clinic, and female gender. This study uncovered risk and protective factors of PTSD in disaster-exposed adolescents. The implications of these findings are considered in relation to determining assessment and interventional strategies aimed at helping survivors following similar traumatic experiences. © 2018 The Korean Academy of Medical Sciences.

Posttraumatic stress disorder caused by the misattribution of seizure-related experiential responses

2011-01-01

Patients with temporal lobe seizures sometimes experience what John Hughlings Jackson described as “dreamy states” during seizure onset. These phenomena may be characterized by a re-experiencing of past events, feelings of familiarity (déjà vu), and hallucinations. In previous reports, patients have been aware of the illusory nature of their experiences. Here, however, the case of a patient with a documented 37-year history of temporal lobe epilepsy who is not aware is described. Fifteen years ago, the patient saw visions of traumatic autobiographical events that he had never previously recalled. He believed them to be veridical memories from his childhood, although evidence from his family suggests that they were not. The patient’s psychological reaction to the “recovery” of these traumatic “memories” was severe enough to qualify as posttraumatic stress disorder (PTSD). To our knowledge, this is the first report of PTSD caused by the misattribution of mental states that accompany a seizure. PMID:21035405

Seizures below one minute in duration are difficult to assess correctly using seizure detection algorithms. We aimed to improve neonatal detection algorithm performance for short seizures through the use of trend templates for seizure onset and end. Bipolar EEG were recorded within a transiently asphyxiated ovine model at 0.7 gestational age, a common experimental model for studying brain development in humans of 30-34 weeks of gestation. Transient asphyxia led to electrographic seizures within 6-8 h. A total of 3159 seizures, 2386 shorter than one minute, were annotated in 1976 h-long EEG recordings from 17 foetal lambs. To capture EEG characteristics, five features, sensitive to seizures, were calculated and used to derive trend information. Feature values and trend information were used as input for support vector machine classification and subsequently post-processed. Performance metrics, calculated after post-processing, were compared between analyses with and without employing trend information. Detector performance was assessed after five-fold cross-validation conducted ten times with random splits. The use of trend templates for seizure onset and end in a neonatal seizure detection algorithm significantly improves the correct detection of short seizures using two-channel EEG recordings from 54.3% (52.6-56.1) to 59.5% (58.5-59.9) at FDR 2.0 (median (range); p < 0.001, Wilcoxon signed rank test). Using trend templates might therefore aid in detection of short seizures by EEG monitoring at the NICU.

Evidence is presented that Alexander the Great, Captain James Cook, Emily Dickinson, and Florence Nightingale each developed symptoms consistent with post-traumatic stress disorder in the aftermath of repeated potentially traumatizing events of differing character. Their case histories also varied with respect to background, premorbid personality style, risk factors, clinical presentation, and course of the illness, illustrating the pleomorphic character of the disorder, as well as the special problems in diagnosing it in historical figures.

Early Activation of Ventral Hippocampus and Subiculum during Spontaneous Seizures in a Rat Model of Temporal Lobe Epilepsy

PubMed Central

Toyoda, Izumi; Bower, Mark R.; Leyva, Fernando

2013-01-01

Temporal lobe epilepsy is the most common form of epilepsy in adults. The pilocarpine-treated rat model is used frequently to investigate temporal lobe epilepsy. The validity of the pilocarpine model has been challenged based largely on concerns that seizures might initiate in different brain regions in rats than in patients. The present study used 32 recording electrodes per rat to evaluate spontaneous seizures in various brain regions including the septum, dorsomedial thalamus, amygdala, olfactory cortex, dorsal and ventral hippocampus, substantia nigra, entorhinal cortex, and ventral subiculum. Compared with published results from patients, seizures in rats tended to be shorter, spread faster and more extensively, generate behavioral manifestations more quickly, and produce generalized convulsions more frequently. Similarities to patients included electrographic waveform patterns at seizure onset, variability in sites of earliest seizure activity within individuals, and variability in patterns of seizure spread. Like patients, the earliest seizure activity in rats was recorded most frequently within the hippocampal formation. The ventral hippocampus and ventral subiculum displayed the earliest seizure activity. Amygdala, olfactory cortex, and septum occasionally displayed early seizure latencies, but not above chance levels. Substantia nigra and dorsomedial thalamus demonstrated consistently late seizure onsets, suggesting their unlikely involvement in seizure initiation. The results of the present study reveal similarities in onset sites of spontaneous seizures in patients with temporal lobe epilepsy and pilocarpine-treated rats that support the model's validity.

Remembering Collective Violence: Broadening the Notion of Traumatic Memory in Post-Conflict Rehabilitation.

In the aftermath of war and armed conflict, individuals and communities face the challenge of dealing with recollections of violence and atrocity. This article aims to contribute to a better understanding of processes of remembering and forgetting histories of violence in post-conflict communities and to reflect on related implications for trauma rehabilitation in post-conflict settings. Starting from the observation that memory operates at the core of PTSD symptomatology, we more closely explore how this notion of traumatic memory is conceptualized within PTSD-centered research and interventions. Subsequently, we aim to broaden this understanding of traumatic memory and post-trauma care by connecting to findings from social memory studies and transcultural trauma research. Drawing on an analysis of scholarly literature, this analysis develops into a perspective on memory that moves beyond a symptomatic framing toward an understanding of memory that emphasizes its relational, political, moral, and cultural nature. Post-conflict memory is presented as inextricably embedded in communal relations, involving ongoing trade-offs between individual and collective responses to trauma and a complex negotiation of speech and silence. In a concluding discussion, we develop implications of this broadened understanding for post-conflict trauma-focused rehabilitation.

Treating acute seizures with benzodiazepines: does seizure duration matter?

PubMed

Naylor, David E

2014-10-01

Several clinical trials have shown improved seizure control and outcome by early initiation of treatment with benzodiazepines, before arrival in the emergency department and before intravenous access can be established. Here, evidence is provided and reviewed for rapid treatment of acute seizures in order to avoid the development of benzodiazepine pharmacoresistance and the emergence of self-sustaining status epilepticus. Alterations in the physiology, pharmacology, and postsynaptic level of GABA-A receptors can develop within minutes to an hour and hinder the ability of synaptic inhibition to stop seizures while also impairing the efficacy of GABAergic agents, such as benzodiazepines, to boost impaired inhibition. In addition, heightened excitatory transmission further exacerbates the inhibitory/excitatory balance and makes seizure control even more resistant to treatment. The acute increase in the surface expression of NMDA receptors during prolonged seizures also may cause excitotoxic injury, cell death, and other pathological expressions and re-arrangements of receptor subunits that all contribute to long-term sequelae such as cognitive impairment and chronic epilepsy. In conclusion, a short window of opportunity exists when seizures are maximally controlled by first-line benzodiazepine treatment. After that, multiple pathological mechanisms quickly become engaged that make seizures increasingly more difficult to control with high risk for long-term harm.

To characterize the risk for seizures over time in relation to EEG findings in hospitalized adults undergoing continuous EEG monitoring (cEEG). Retrospective analysis of cEEG data and medical records from 625 consecutive adult inpatients monitored at a tertiary medical center. Using survival analysis methods, we estimated the time-dependent probability that a seizure will occur within the next 72-h, if no seizure has occurred yet, as a function of EEG abnormalities detected so far. Seizures occurred in 27% (168/625). The first seizure occurred early (<30min of monitoring) in 58% (98/168). In 527 patients without early seizures, 159 (30%) had early epileptiform abnormalities, versus 368 (70%) without. Seizures were eventually detected in 25% of patients with early epileptiform discharges, versus 8% without early discharges. The 72-h risk of seizures declined below 5% if no epileptiform abnormalities were present in the first two hours, whereas 16h of monitoring were required when epileptiform discharges were present. 20% (74/388) of patients without early epileptiform abnormalities later developed them; 23% (17/74) of these ultimately had seizures. Only 4% (12/294) experienced a seizure without preceding epileptiform abnormalities. Seizure risk in acute neurological illness decays rapidly, at a rate dependent on abnormalities detected early during monitoring. This study demonstrates that substantial risk stratification is possible based on early EEG abnormalities. These findings have implications for patient-specific determination of the required duration of cEEG monitoring in hospitalized patients.

This study examined the unique effects of child sexual abuse simultaneously with post-traumatic stress disorder symptom clusters, problem drinking, and illicit drug use in relation to sexual revictimization in a community sample of female adult sexual assault victims. Participants (N=555) completed two surveys a year apart. Child sexual abuse predicted more post-traumatic stress disorder symptoms in adult sexual assault victims. Posttraumatic stress disorder numbing symptoms directly predicted revictimization, whereas other post-traumatic stress disorder symptoms (reexperiencing, avoidance, and arousal) were related to problem drinking, which in turn predicted revictimization. Thus, numbing symptoms and problem drinking may be independent risk factors for sexual revictimization in adult sexual assault victims, particularly for women with a history of childhood sexual abuse.

Post-traumatic Stress Disorder Symptoms Resulting from Torture and Other Traumatic Events among Syrian Kurdish Refugees in Kurdistan Region, Iraq

Political violence is known to cause psychological distress. There is a large body of empirical studies drawing correlations between war trauma, torture, and post-traumatic stress disorder (PTSD). However, there are few studies on the effects of war-related trauma among Syrian refugees after events following the ‘Arab Spring’ uprisings between 2010 and 2012. This study examines the association of PTSD symptoms with torture and other traumatic events among Syrian Kurdish refugees living in Kurdistan Region, Iraq. The experiences and PTSD symptoms among 91 Syrian Kurdish refugees in the Arbat camp in the Sulaymaniyah Governorate of the Kurdistan Region of Iraq were assessed using the Harvard Trauma Questionnaire, sections I, IV, and V. Results showed that the estimated levels of PTSD symptoms were high: between 35 and 38%. There were no significant gender differences in the occurrence of PTSD symptoms. However, men reported more general traumatic experiences than women. There were significant positive correlations between PTSD symptoms with traumatic events and torture (r = 0.500, r = 0.366, respectively). Examining the mental health impact of torture and other traumatic events among refugees has possible implications for organizations managing rehabilitation programs for individuals who have been exposed to traumatic events.

Psychological resilience and post-traumatic growth in disaster-exposed organisations: overview of the literature.

PubMed

Brooks, Samantha; Amlôt, R; Rubin, G J; Greenberg, N

2018-02-02

As disasters become increasingly prevalent, and reported on, a wealth of literature on post-disaster mental health has been published. Most published evidence focuses on symptoms of mental health problems (such as post-traumatic stress disorder, depression and anxiety) and psychosocial factors increasing the risk of such symptoms. However, a recent shift in the literature has moved to exploring resilience and the absence of adverse lasting mental health effects following a disaster. This paper undertakes a qualitative review of the literature to explore factors affecting psychological resilience, as well as the potential positive impact of experiencing a disaster (post-traumatic growth) by examining the literature on employees in disaster-exposed organisations. We identify several protective factors: training, experience, and perceived (personal) competence; social support; and effective coping strategies. Post-traumatic growth frequently appeared to occur at both personal and professional levels for those rescue staff after a disaster, giving employees a greater appreciation of life and their relationships, enhancing their self-esteem and providing a sense of accomplishment and better understanding of their work. Implications, in terms of how to build a resilient workforce, are discussed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Awake craniotomies (AC) could reduce neurological deficits compared with patients under general anesthesia, however, intraoperative seizure is a major reason causing awake surgery failure. The purpose of the study was to give a comprehensive overview the published articles focused on seizure incidence in awake craniotomy. Bibliographic searches of the EMBASE, MEDLINE,were performed to identify articles and conference abstracts that investigated the intraoperative seizure frequency of patients underwent AC. Twenty-five studies were included in this meta-analysis. Among the 25 included studies, one was randomized controlled trials and 5 of them were comparable studies. The pooled data suggested the general intraoperative seizure(IOS) rate for patients with AC was 8%(fixed effect model), sub-group analysis identified IOS rate for glioma patients was 8% and low grade patients was 10%. The pooled data showed early seizure rates of AC patients was 11% and late seizure rates was 35%. This systematic review and meta-analysis shows that awake craniotomy is a safe technique with relatively low intraoperative seizure occurrence. However, few RCTs were available, and the acquisition of further evidence through high-quality RCTs is highly recommended.
