    Sports-related concussion has gained increased prominence, in part due to media coverage of several well-known athletes who have died from consequences of chronic traumatic encephalopathy (CTE). CTE was first described by Martland in 1928 as a syndrome seen in boxers who had experienced significant head trauma from repeated blows. The classic symptoms of impaired cognition, mood, behavior, and motor skills also have been reported in professional football players, and in 2005, the histopathological findings of CTE were first reported in a former National Football League (NFL) player. These finding were similar to Alzheimer's disease in some ways but differed in critical areas such as a predominance of tau protein deposition over amyloid. The pathophysiology is still unknown but involves a history of repeated concussive and subconcussive blows and then a lag period before CTE symptoms become evident. The involvement of excitotoxic amino acids and abnormal microglial activation remain speculative. Early identification and prevention of this disease by reducing repeated blows to the head has become a critical focus of current research.

    Chronic traumatic encephalopathy is a neurodegenerative disease produced by accumulated minor traumatic brain injuries; no definitive premortem diagnosis and no treatments are available for chronic traumatic encephalopathy. Risk factors associated with chronic traumatic encephalopathy include playing contact sports, presence of the apolipoprotein E4, and old age. Although it shares certain histopathological findings with Alzheimer disease, chronic traumatic encephalopathy has a more specific presentation (hyperphosphorylated tau protein deposited as neurofibrillary tangles, associated with neuropil threads and sometimes with beta-amyloid plaques). Its clinical presentation is insidious; patients show mild cognitive and emotional symptoms before progressing to parkinsonian motor signs and finally dementia. Results from new experimental diagnostic tools are promising, but these tools are not yet available. The mainstay of managing this disease is prevention and early detection of its first symptoms.

    2016-01-01

    For nearly 80 years, suicidality was not considered to be a core clinical feature of chronic traumatic encephalopathy (CTE). In recent years, suicide has been widely cited as being associated with CTE, and now depression has been proposed to be one of three core diagnostic features alongside cognitive impairment and anger control problems. This evolution of the clinical features has been reinforced by thousands of media stories reporting a connection between mental health problems in former athletes and military veterans, repetitive neurotrauma, and CTE. At present, the science underlying the causal assumption between repetitive neurotrauma, depression, suicide, and the neuropathology believed to be unique to CTE is inconclusive. Epidemiological evidence indicates that former National Football League players, for example, are at lower, not greater, risk for suicide than men in the general population. This article aims to discuss the critical issues and literature relating to these possible relationships.

    Full Text Available Chronic traumatic encephalopathy (CTE is a progressive neurodegenerative disease that is a long-term consequence of single or repetitive closed head injuries for which there is no treatment and no definitive pre-mortem diagnosis. It has been closely tied to athletes who participate in contact sports like boxing, American football, soccer, professional wrestling and hockey. Risk factors include head trauma, presence of ApoE3 or ApoE4 allele, military service, and old age. It is histologically identified by the presence of tau-immunoreactive NFTs and NTs with some cases having a TDP-43 proteinopathy or beta-amyloid plaques. It has an insidious clinical presentation that begins with cognitive and emotional disturbances and can progress to Parkinsonian symptoms. The exact mechanism for CTE has not been precisely defined however, research suggest it is due to an ongoing metabolic and immunologic cascade called immunoexcitiotoxicity. Prevention and education are currently the most compelling way to combat CTE and will be an emphasis of both physicians and athletes. Further research is needed to aid in pre-mortem diagnosis, therapies, and support for individuals and their families living with CTE.

  6. Is chronic traumatic encephalopathy a real disease?

    Science.gov (United States)

    Randolph, Christopher

    2014-01-01

    Chronic traumatic encephalopathy (CTE) has received widespread media attention and is treated in the lay press as an established disease, characterized by suicidality and progressive dementia. The extant literature on CTE is reviewed here. There currently are no controlled epidemiological data to suggest that retired athletes are at increased risk for dementia or that they exhibit any type of unique neuropathology. There remain no established clinical or pathological criteria for diagnosing CTE. Despite claims that CTE occurs frequently in retired National Football League (NFL) players, recent studies of NFL retirees report that they have an all-cause mortality rate that is approximately half of the expected rate, and even lower suicide rates. In addition, recent clinical studies of samples of cognitively impaired NFL retirees have failed to identify any unique clinical syndrome. Until further controlled studies are completed, it appears to be premature to consider CTE a verifiable disease.

    Chronic traumatic encephalopathy is a progressive neurodegenerative disease characterized by neurofibrillary tau tangles following repetitive neurotrauma. The underlying mechanism linking traumatic brain injury to chronic traumatic encephalopathy has not been elucidated. The authors investigate the role of endoplasmic reticulum stress as a link between acute neurotrauma and chronic neurodegeneration. The authors used pharmacological, biochemical, and behavioral tools to assess the role of endoplasmic reticulum stress in linking acute repetitive traumatic brain injury to the development of chronic neurodegeneration. Data from the authors' clinically relevant and validated rodent blast model were compared with those obtained from postmortem human chronic traumatic encephalopathy specimens from a National Football League player and World Wrestling Entertainment wrestler. The results demonstrated strong correlation of endoplasmic reticulum stress activation with subsequent tau hyperphosphorylation. Various endoplasmic reticulum stress markers were increased in human chronic traumatic encephalopathy specimens, and the endoplasmic reticulum stress response was associated with an increase in the tau kinase, glycogen synthase kinase-3β. Docosahexaenoic acid, an endoplasmic reticulum stress inhibitor, improved cognitive performance in the rat model 3 weeks after repetitive blast exposure. The data showed that docosahexaenoic acid administration substantially reduced tau hyperphosphorylation (t = 4.111, p < 0.05), improved cognition (t = 6.532, p < 0.001), and inhibited C/EBP homology protein activation (t = 5.631, p < 0.01). Additionally the data showed, for the first time, that endoplasmic reticulum stress is involved in the pathophysiology of chronic traumatic encephalopathy. Docosahexaenoic acid therefore warrants further investigation as a potential therapeutic agent for the prevention of chronic traumatic encephalopathy.

  11. Chronic traumatic encephalopathy and other neurodegenerative proteinopathies

    Maria Carmela Tartaglia

    2014-01-01

    Full Text Available Chronic traumatic encephalopathy (CTE is described as a slowly progressive neurodegenerative disease believed to result from multiple concussions. Traditionally, concussions were considered benign events and although most people recover fully, about 10% develop a post-concussive syndrome with persisting neurological, cognitive and neuropsychiatric symptoms. CTE was once thought to be unique to boxers, but it has now been observed in many different athletes having suffered multiple concussions as well as in military personal after repeated blast injuries. Much remains unknown about the development of CTE but its pathological substrate is usually tau, similar to that seen in Alzheimer’s disease and frontotemporal lobar degeneration. The aim of this perspective is to compare and contrast clinical and pathological CTE with the other neurodegenerative proteinopathies and highlight that there is an urgent need for understanding the relationship between concussion and the development of CTE as it may provide a window into the development of a proteinopathy and thus new avenues for treatment.

    Growing public health concern exists over the incidence of chronic traumatic brain injury (TBI) in athletes participating in contact sports. Chronic TBI represents a spectrum of disorders associated with long-term consequences of single or repetitive TBI and includes chronic traumatic encephalopathy (CTE), chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologists should be familiar with the different types of chronic TBI and their diagnostic criteria. CTE is the most severe chronic TBI and represents the neurologic consequences of repetitive mild TBI. It is particularly noted among boxers and football players. CTE presents with behavioral, cognitive, and motor symptoms, and can only be definitively diagnosed postmortem. Chronic postconcussion syndrome is defined as postconcussion symptoms that last longer than 1 year and do not appear to resolve; it may develop after a single concussive event. Chronic neurocognitive impairment is an all-encompassing clinical term denoting long-term neurologic sequelae secondary to sports-related trauma and can present either within the postconcussion syndrome or years after a symptom-free interval. This article discusses the diagnostic evaluation of chronic TBI, including clinical history, neurologic examination, neuropsychological testing, neuroimaging, and laboratory testing, as well as the distinctions between CTE, chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologic impairment among athletes exposed to repetitive brain injury appears to be a real phenomenon. Because CTE has no established treatment, prevention is of paramount importance for athletes participating in contact sports.

    Full Text Available Niklaus Egloff,1 Anna Hirschi,2 Roland von Känel1 1Department of General Internal Medicine, Division of Psychosomatic Medicine, Inselspital, University Hospital, Bern, Switzerland; 2Outpatient Clinic for Victims of Torture and War, Swiss Red Cross, Bern-Wabern, Switzerland Abstract: Up to 80% of patients with severe posttraumatic stress disorder are suffering from “unexplained” chronic pain. Theories about the links between traumatization and chronic pain have become the subject of increased interest over the last several years. We will give a short summary about the existing interaction models that emphasize particularly psychological and behavioral aspects of this interaction. After a synopsis of the most important psychoneurobiological mechanisms of pain in the context of traumatization, we introduce the hypermnesia–hyperarousal model, which focuses on two psychoneurobiological aspects of the physiology of learning. This hypothesis provides an answer to the hitherto open question about the origin of pain persistence and pain sensitization following a traumatic event and also provides a straightforward explanatory model for educational purposes.

    Recently, the pathobiology, causes, associated factors, incidence and prevalence, and natural history of chronic traumatic encephalopathy (CTE) have been debated. Data from retrospective case series and high-profile media reports have fueled public fear and affected the medical community's understanding of the role of sports-related traumatic brain injury (TBI) in the development of CTE. There are a number of limitations posed by the current evidence that can lead to confusion within the public and scientific community. In this paper, the authors address common questions surrounding the science of CTE and propose future research directions.

    Full Text Available Repetitive brain trauma is associated with a progressive neurological deterioration, now termed as chronic traumatic encephalopathy (CTE. Although research on the long-term effects of TBI is advancing quickly, the incidence and prevalence of post-traumatic neurodegeneration and CTE are unknown. The incidence and prevalence of chronic traumatic encephalopathy and the genetic risk factors critical to its development are currently under research. CTE can be diagnosed only by post mortem neuropathological examination of the brain. Great efforts are being made to better understand the clinical signs and symptoms of CTE, obtained in most cases retrospectively from families of affected persons.Patients with CTE are described as having behavioral, mood, cognitive and motor impairments, occurring after a long latency from the traumatic events. Recent pathogenetic studies have provided new insights to CTE mechanisms, offering important clues in understanding neurodegenerative process and relations between physical factors and pathologic protein deposition. Further research is needed to better identify the genetic and environmental risk factors for CTE, as well as rehabilitation and treatment strategies.

    Chronic traumatic encephalopathy (CTE) is a form of neurodegeneration that results from repetitive brain trauma. Not surprisingly, CTE has been linked to participation in contact sports such as boxing, hockey and American football. In American football getting "dinged" equates to moments of dizziness, confusion, or grogginess that can follow a blow to the head. There are approximately 100,000 to 300,000 concussive episodes occurring in the game of American football alone each year. It is beli...

    Traumatic brain injury can lead to the neurodegenerative disease chronic traumatic encephalopathy. This condition has a clear neuropathological definition but the relationship between the initial head impact and the pattern of progressive brain pathology is poorly understood. We test the hypothesis that mechanical strain and strain rate are greatest in sulci, where neuropathology is prominently seen in chronic traumatic encephalopathy, and whether human neuroimaging observations converge with computational predictions. Three distinct types of injury were simulated. Chronic traumatic encephalopathy can occur after sporting injuries, so we studied a helmet-to-helmet impact in an American football game. In addition, we investigated an occipital head impact due to a fall from ground level and a helmeted head impact in a road traffic accident involving a motorcycle and a car. A high fidelity 3D computational model of brain injury biomechanics was developed and the contours of strain and strain rate at the grey matter-white matter boundary were mapped. Diffusion tensor imaging abnormalities in a cohort of 97 traumatic brain injury patients were also mapped at the grey matter-white matter boundary. Fifty-one healthy subjects served as controls. The computational models predicted large strain most prominent at the depths of sulci. The volume fraction of sulcal regions exceeding brain injury thresholds were significantly larger than that of gyral regions. Strain and strain rates were highest for the road traffic accident and sporting injury. Strain was greater in the sulci for all injury types, but strain rate was greater only in the road traffic and sporting injuries. Diffusion tensor imaging showed converging imaging abnormalities within sulcal regions with a significant decrease in fractional anisotropy in the patient group compared to controls within the sulci. Our results show that brain tissue deformation induced by head impact loading is greatest in sulcal locations

    Chronic Traumatic Encephalopathy (CTE) is a neurodegenerative disease associated with repetitive brain trauma (RBT). Initially described in boxers, CTE has now been found in other contact sport athletes with a history of RBT. In recent years, there has been tremendous media attention regarding CTE, primarily because of the deaths of high profile American football players who were found to have CTE upon neuropathological examination. However, the study of CTE remains in its infancy. This review focuses on research from the Centre for the Study of Traumatic Encephalopathy (CSTE) at Boston University. This study reviews the formation of the CSTE, major CSTE publications and current ongoing research projects at the CSTE. The neuropathology of CTE has been well-described. Current research focuses on: methods of diagnosing the disease during life (including the development of biomarkers), examination of CTE risk factors (including genetic susceptibility and head impact exposure variables); description of the clinical presentation of CTE; development of research diagnostic criteria for Traumatic Encephalopathy Syndrome; and assessment of mechanism and pathogenesis. Current research at the BU CSTE is aimed at increasing understanding of the long-term consequences of repetitive head impacts and attempting to begin to answer several of the unanswered questions regarding CTE.

    Tait, Raymond C; Ferguson, McKenzie; Herndon, Christopher M

    2017-01-01

    Chronic orofacial pain is a symptom associated with a wide range of neuropathic, neurovascular, idiopathic, and myofascial conditions that affect a significant proportion of the population. While the collective impact of the subset of the orofacial pain disorders involving neurogenic and idiopathic mechanisms is substantial, some of these are relatively uncommon. Hence, patients with these disorders can be vulnerable to misdiagnosis, sometimes for years, increasing the symptom burden and delaying effective treatment. This manuscript first reviews the decision tree to be followed in diagnosing any neuropathic pain condition, as well as the levels of evidence needed to make a diagnosis with each of several levels of confidence: definite, probable, or possible. It then examines the clinical literature related to the idiopathic and neurogenic conditions that can occasion chronic orofacial pain, including burning mouth syndrome, trigeminal neuralgia, glossopharyngeal neuralgia, post-herpetic neuralgia, and atypical odontalgia. Temporomandibular disorders also are examined as are other headache conditions, even though they are not neurologic conditions, because they are common and can mimic symptoms of the latter disorders. For each of these conditions, the paper reviews literature regarding incidence and prevalence, physiologic and other contributing factors, diagnostic signs and symptoms, and empirical evidence regarding treatments. Finally, in order to improve the quality and accuracy of clinical diagnosis, as well as the efficiency with which effective treatment is initiated and delivered, criteria are offered that can be instrumental in making a differential diagnosis.

  7. Chronic traumatic encephalopathy-integration of canonical traumatic brain injury secondary injury mechanisms with tau pathology.

    Science.gov (United States)

    Kulbe, Jacqueline R; Hall, Edward D

    2017-11-01

    In recent years, a new neurodegenerative tauopathy labeled Chronic Traumatic Encephalopathy (CTE), has been identified that is believed to be primarily a sequela of repeated mild traumatic brain injury (TBI), often referred to as concussion, that occurs in athletes participating in contact sports (e.g. boxing, American football, Australian football, rugby, soccer, ice hockey) or in military combatants, especially after blast-induced injuries. Since the identification of CTE, and its neuropathological finding of deposits of hyperphosphorylated tau protein, mechanistic attention has been on lumping the disorder together with various other non-traumatic neurodegenerative tauopathies. Indeed, brains from suspected CTE cases that have come to autopsy have been confirmed to have deposits of hyperphosphorylated tau in locations that make its anatomical distribution distinct for other tauopathies. The fact that these individuals experienced repetitive TBI episodes during their athletic or military careers suggests that the secondary injury mechanisms that have been extensively characterized in acute TBI preclinical models, and in TBI patients, including glutamate excitotoxicity, intracellular calcium overload, mitochondrial dysfunction, free radical-induced oxidative damage and neuroinflammation, may contribute to the brain damage associated with CTE. Thus, the current review begins with an in depth analysis of what is known about the tau protein and its functions and dysfunctions followed by a discussion of the major TBI secondary injury mechanisms, and how the latter have been shown to contribute to tau pathology. The value of this review is that it might lead to improved neuroprotective strategies for either prophylactically attenuating the development of CTE or slowing its progression.

    2013-01-01

    Full Text Available Traumatic brain injury (TBI is a global health concern, and the recent literature reports that a single mild TBI can result in chronic traumatic encephalopathy (CTE. It has been suggested that CTE may lead to death by suicide, raising important prevention, treatment, and policy implications. Thus, we conducted a systematic review of the medical literature to answer the key question: What is the existing evidence in support of a relationship between CTE and suicide? Systematic searches of CTE and suicide yielded 85 unique abstracts. Seven articles were identified for full text review. Only two case series met inclusion criteria and included autopsies from 17 unique cases, 5 of whom died by suicide. Neither studies used blinding, control cases, or systematic data collection regarding TBI exposure and/or medical/neuropsychiatric history. The identified CTE literature revealed divergent opinions regarding neuropathological elements of CTE and heterogeneity regarding clinical manifestations. Overall quality of evidence regarding a relationship between CTE and suicide was rated as very low using Grading of Recommendations Assessment, Development and Evaluation Working Group (GRADE criteria. Further studies of higher quality and methodological rigor are needed to determine the existence and nature of any relationship between CTE and suicide.

    Over the past decade, public awareness of the long-term pathological consequences of traumatic brain injury (TBI) has increased. Such awareness has been stimulated mainly by reports of progressive neurological dysfunction in athletes exposed to repetitive concussions in high-impact sports such as boxing and American football, and by the rising number of TBIs in war veterans who are now more likely to survive explosive blasts owing to improved treatment. Moreover, the entity of chronic traumatic encephalopathy (CTE)--which is marked by prominent neuropsychiatric features including dementia, parkinsonism, depression, agitation, psychosis, and aggression--has become increasingly recognized as a potential late outcome of repetitive TBI. Annually, about 1% of the population in developed countries experiences a clinically relevant TBI. The goal of this Review is to provide an overview of the latest understanding of CTE pathophysiology, and to delineate the key issues that are challenging clinical and research communities, such as accurate quantification of the risk of CTE, and development of reliable biomarkers for single-incident TBI and CTE.

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease characterized by a distinct pattern of hyperphosphorylated tau (p-tau). Thought to be caused by repetitive concussive and subconcussive injuries, CTE is considered largely preventable. The majority of neuropathologically confirmed cases have occurred in professional contact sport athletes (eg, boxing, football). A recent post-mortem case series has magnified concerns for the public's health following its identification in six high school level athletes. CTE is diagnosed with certainty only following a post-mortem autopsy. Efforts to define the etiology and clinical progression during life are ongoing. The goal of this article is to characterize the clinical concepts associated with short- and long-term effects of repetitive traumatic brain injury, with a special emphasis on new clinical diagnostic criteria for CTE. Utilizing these new diagnostic criteria, two cases of neuropathologically confirmed CTE, one in a professional football player and one in a professional boxer, are reported. Differences in cerebellar pathology in CTE confirmed cases in boxing and football are discussed. © 2015 International Society of Neuropathology.

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease that is most often identified in postmortem autopsies of individuals exposed to repetitive head impacts, such as boxers and football players. The neuropathology of CTE is characterized by the accumulation of hyperphosphorylated tau protein in a pattern that is unique from that of other neurodegenerative diseases, including Alzheimer's disease. The clinical features of CTE are often progressive, leading to dramatic changes in mood, behavior, and cognition, frequently resulting in debilitating dementia. In some cases, motor features, including parkinsonism, can also be present. In this review, the historical origins of CTE are revealed and an overview of the current state of knowledge of CTE is provided, including the neuropathology, clinical features, proposed clinical and pathological diagnostic criteria, potential in vivo biomarkers, known risk factors, and treatment options.

    Full Text Available Despite the extensive media coverage associated with the diagnosis of chronic traumatic encephalopathy (CTE, our fundamental understanding of the disease pathophysiology remains in its infancy. Only recently have scientific laboratories and personnel begun to explore CTE pathophysiology through the use of preclinical models of neurotrauma. Some studies have shown the ability to recapitulate some aspects of CTE in rodent models, through the use of various neuropathologic, biochemical, and/or behavioral assays. Many questions related to CTE development however remain unanswered. These include the role of impact severity, the time interval between impacts, the age at which impacts occur, and the total number of impacts sustained. Other important variables such as the location of impacts, character of impacts, and effect of environment/lifestyle and genetics also warrant further study. In this work we attempt to address some of these questions by exploring work previously completed using single and repetitive injury paradigms. Despite some models producing some deficits similar to CTE symptoms, it is clear that further studies are required to understand the development of neuropathological and neurobehavioral features consistent with CTE-like features in rodents. Specifically, acute and chronic studies are needed that characterize the development of tau-based pathology.

    The chronic effects of repetitive head impacts (RHI) on the development of neuroinflammation and its relationship to chronic traumatic encephalopathy (CTE) are unknown. Here we set out to determine the relationship between RHI exposure, neuroinflammation, and the development of hyperphosphorylated tau (ptau) pathology and dementia risk in CTE. We studied a cohort of 66 deceased American football athletes from the Boston University-Veteran's Affairs-Concussion Legacy Foundation Brain Bank as well as 16 non-athlete controls. Subjects with a neurodegenerative disease other than CTE were excluded. Counts of total and activated microglia, astrocytes, and ptau pathology were performed in the dorsolateral frontal cortex (DLF). Binary logistic and simultaneous equation regression models were used to test associations between RHI exposure, microglia, ptau pathology, and dementia. Duration of RHI exposure and the development and severity of CTE were associated with reactive microglial morphology and increased numbers of CD68 immunoreactive microglia in the DLF. A simultaneous equation regression model demonstrated that RHI exposure had a significant direct effect on CD68 cell density (p CTE. Inflammatory molecules may be important diagnostic or predictive biomarkers as well as promising therapeutic targets in CTE.

    Repetitive traumatic brain injury (rTBI) is one of the major risk factors for the abnormal deposition of phosphorylated tau (PT) in the brain and chronic traumatic encephalopathy (CTE). CTE and temporal lobe epilepsy (TLE) affect the limbic system, but no comparative studies on PT distribution in TLE and CTE are available. It is also unclear whether PT pathology results from repeated head hits (rTBI). These gaps prevent a thorough understanding of the pathogenesis and clinical significance of PT, limiting our ability to develop preventative and therapeutic interventions. We quantified PT in TLE and CTE to unveil whether a history of rTBI is a prerequisite for PT accumulation in the brain. Six postmortem CTE (mean 73.3 years) and age matched control samples were compared to 19 surgically resected TLE brain specimens (4 months-58 years; mean 27.6 years). No history of TBI was present in TLE or control; all CTE patients had a history of rTBI. TLE and CTE brain displayed increased levels of PT as revealed by immunohistochemistry. No age-dependent changes were noted, as PT was present as early as 4 months after birth. In TLE and CTE, cortical neurons, perivascular regions around penetrating pial vessels and meninges were immunopositive for PT; white matter tracts also displayed robust expression of extracellular PT organized in bundles parallel to venules. Microscopically, there were extensive tau-immunoreactive neuronal, astrocytic and degenerating neurites throughout the brain. In CTE perivascular tangles were most prominent. Overall, significant differences in staining intensities were found between CTE and control (PCTE and TLE (P=0.08). pS199 tau analysis showed that CTE had the most high molecular weight tangle-associated tau, whereas epileptic brain contained low molecular weight tau. Tau deposition may not be specific to rTBI since TLE recapitulated most of the pathological features of CTE. Copyright © 2015 Elsevier B.V. All rights reserved.

  19. Chronic traumatic encephalopathy and risk of suicide in former athletes.

    Iverson, Grant L

    2014-01-01

    In the initial autopsy case studies of chronic traumatic encephalopathy (CTE), some researchers have concluded that the proteinopathy associated with CTE is the underlying cause of suicidality and completed suicide in former athletes. A review of the literature on contact sports and risk of completed suicide revealed only one epidemiological study with direct relevant data. There are no published cross-sectional, epidemiological or prospective studies showing a relation between contact sports and risk of suicide. One published epidemiological study suggests that retired National Football League players have lower rates of death by suicide than the general population. Outside of sports, there is a mature body of evidence suggesting that the causes of suicide are complex, multifactorial and difficult to predict in individual cases. Future research might establish a clear causal connection between the proteinopathy of CTE and suicide. At present, however, there is insufficient scientific evidence to conclude that there is a strong causal relationship between the presence of these proteinopathies and suicide in former athletes. Additional research is needed to determine the extent to which the neuropathology of CTE is a possible mediator or moderator variable associated with suicide.

  20. Chronic traumatic encephalopathy: the dangers of getting "dinged".

    Chronic traumatic encephalopathy (CTE) is a form of neurodegeneration that results from repetitive brain trauma. Not surprisingly, CTE has been linked to participation in contact sports such as boxing, hockey and American football. In American football getting "dinged" equates to moments of dizziness, confusion, or grogginess that can follow a blow to the head. There are approximately 100,000 to 300,000 concussive episodes occurring in the game of American football alone each year. It is believed that repetitive brain trauma, with or possibly without symptomatic concussion, sets off a cascade of events that result in neurodegenerative changes highlighted by accumulations of hyperphosphorylated tau and neuronal TAR DNA-binding protein-43 (TDP-43). Symptoms of CTE may begin years or decades later and include a progressive decline of memory, as well as depression, poor impulse control, suicidal behavior, and, eventually, dementia similar to Alzheimer's disease. In some individuals, CTE is also associated with motor neuron disease similar to amyotrophic lateral sclerosis. Given the millions of athletes participating in contact sports that involve repetitive brain trauma, CTE represents an important public health issue. In this review, we discuss recent advances in understanding the etiology of CTE. It is now known that those instances of mild concussion or "dings" that we may have previously not noticed could very well be causing progressive neurodegenerative damage to a player's brain. In the future, focused and intensive study of the risk factors could potentially uncover methods to prevent and treat this disease.

    - Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease caused by repetitive head injuries like those seen in sports such as boxing, American football and soccer.- The clinical features of CTE are a range of cognitive, psychiatric and motor symptoms, and histopathology involves deposits of hyperphosphorylated tau protein and the presence of TAR DNA-binding protein (TDP-43) with relatively little beta-amyloid.- CTE is difficult to differentiate clinically from Alzheimer's disease, frontotemporal dementia and psychiatric disorders because of the major symptom overlap between these conditions.- The most important risk factors for developing CTE are the cumulative effect of repetitive head injuries, with or without clinical symptoms, and the duration of exposure to the repetitive injuries (the sporting career).- There is no treatment for CTE at present and the strategy must be primarily geared to prevention.- In view of the large number of people, including those in the Netherlands, who take part in sports in which head injuries may occur, research into CTE is of major societal importance.

    A disease initially associated with boxers ninety years ago, chronic traumatic encephalopathy (CTE) is now recognized as a significant risk to boxers, American football players, ice hockey players, military personnel or anyone to whom recurrent head injuries are a distinct possibility. Diagnosis is currently confirmed at autopsy, although CTE's presumed sufferers have symptoms of depression, suicidal thoughts, mood and personality changes, and loss of memory. CTE sufferers also complain of losing cognitive ability, dysfunction in everyday activities, inability to keep regular employment, violent tendencies and marital strife. Dementia may develop over the long term. Unfortunately, there is no clear consensus in regards to pathology, with both number and severity of head injuries being linked to disease progression. Despite the slow advancement of this disease, there are no clinical methods to diagnose or monitor prognosis in presumed patients, limiting clinicians' efforts to symptom management. The lack of diagnostic tools fuels the need for biomedical engineers to develop techniques for in vivo detection of CTE. This review examines efforts made with various magnetic resonance and nuclear imaging techniques, with a view towards improving the sensitivity and specificity of diagnostic imaging for CTE.

    Patients with chronic neck pain can present with disability, low quality of life, psychological factors and clinical symptoms. It is unclear whether patients with a traumatic onset differ from those with a non-traumatic onset, by having more complex and severe symptoms. The purpose of this study was to investigate the clinical presentation of chronic neck pain patients with and without traumatic onset by examining cervical mobility, sensorimotor function, cervical muscle performance and pressure pain threshold in addition to the following self-reported characteristics: quality of life, neck pain and function, kinesiophobia, depression, and pain bothersomeness. This cross-sectional study included 200 participants with chronic neck pain: 120 with traumatic onset and 80 with non-traumatic onset. Participants were recruited from physiotherapy clinics in primary and secondary health care. For participants to be included, they were required to be at least 18 years of age, have had neck pain for at least 6 months, and experienced neck-related activity limitation as determined by a score of at least 10 on the Neck Disability Index. We conducted the following clinical tests of cervical range of motion, gaze stability, eye movement, cranio-cervical flexion, cervical extensors, and pressure pain threshold. The participants completed the following questionnaires: physical and mental component summary of the Short Form Health Survey, EuroQol-5D, Neck Disability Index, Patient-Specific Functional Scale, Pain Bothersomeness, Beck Depression Inventory-II, and TAMPA scale of kinesiophobia. The level of significance for all analyses was defined as p<0.01. Differences between groups for the continuous data were determined using either a Student's t-test or Mann Whitney U test. In both groups, the majority of the participants were female (approximately 75%). Age, educational level, working situation and sleeping patterns were similar in both groups. The traumatic group had symptoms

  4. Clustering of tau-immunoreactive pathology in chronic traumatic encephalopathy.

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder which may result from repetitive brain injury. A variety of tau-immunoreactive pathologies are present, including neurofibrillary tangles (NFT), neuropil threads (NT), dot-like grains (DLG), astrocytic tangles (AT), and occasional neuritic plaques (NP). In tauopathies, cellular inclusions in the cortex are clustered within specific laminae, the clusters being regularly distributed parallel to the pia mater. To determine whether a similar spatial pattern is present in CTE, clustering of the tau-immunoreactive pathology was studied in the cortex, hippocampus, and dentate gyrus in 11 cases of CTE and 7 cases of Alzheimer's disease neuropathologic change (ADNC) without CTE. In CTE: (1) all aspects of tau-immunoreactive pathology were clustered and the clusters were frequently regularly distributed parallel to the tissue boundary, (2) clustering was similar in two CTE cases with minimal co-pathology compared with cases with associated ADNC or TDP-43 proteinopathy, (3) in a proportion of cortical gyri, estimated cluster size was similar to that of cell columns of the cortico-cortical pathways, and (4) clusters of the tau-immunoreactive pathology were infrequently spatially correlated with blood vessels. The NFT and NP in ADNC without CTE were less frequently randomly or uniformly distributed and more frequently in defined clusters than in CTE. Hence, the spatial pattern of the tau-immunoreactive pathology observed in CTE is typical of the tauopathies but with some distinct differences compared to ADNC alone. The spread of pathogenic tau along anatomical pathways could be a factor in the pathogenesis of the disease.

    We define chronic traumatic encephalopathy (CTE) as a progressive neurodegenerative syndrome caused by single, episodic, or repetitive blunt force impacts to the head and transfer of acceleration-deceleration forces to the brain. We present emerging histomorphologic phenotypes of CTE that we identified in our cohort of CTE cases with apolipoprotein E genotyping and causes and manners of death. Autopsy brain tissue of 14 professional athletes and 3 high school football players was examined after unexpected deaths. Histochemical and immunohistochemical tissue staining was performed with apolipoprotein E genotyping. Ten of 14 professional athletes (71%) were positive for CTE: 7 of 8 football players, 2 of 4 wrestlers, and 1 boxer. One of 3 high school players manifested incipient CTE. The age range of those with CTE was 18 to 52 years; they were all male athletes. In all cases of CTE, Alzheimer-type cerebral cortical atrophy was absent; negligible to mild neocortical neuronal dropout was present. The fundamental neuropathologic feature of CTE was the topographic distribution of sparse, moderate, and frequent band-shaped, flame-shaped, small and large globose neurofibrillary tangles and neuritic threads in the cerebral cortex, subcortical nuclei/basal ganglia, hippocampus, and brainstem nuclei. Sparse to frequent diffuse amyloid plaques may accompany tauopathy and was seen in only 2 CTE cases. No α-synucleinopathy was present. All 7 CTE-positive professional athletes with known apolipoprotein E genotypes had at least 1 E3 allele comprising 5 E3/E3 (71%) and 2 E3/E4 (29%). Alcohol- and drug-related deaths, suicides, and accidental deaths were overrepresented in our CTE cohort. The emerging histomorphologic features of our CTE cohort may specify histologic criteria for CTE diagnosis, may identify emerging histologic variants of CTE and may facilitate more objective surveillance and accurate identification of sentinel CTE cases.

    Background : Trauma exposure and post-traumatic stress disorder (PTSD) are risk factors for chronic pain. Objective: This study investigated how exposure to intentional and non-intentional traumatic events and PTSD are related to pain severity and outcome of treatment in chronic pain patients. Methods : We assessed exposure to potentially traumatizing events, psychiatric diagnosis with structured clinical interview, and pain severity in 63 patients at a secondary multidisciplinary pain clinic at the beginning of treatment, and assessed level of pain at follow up. Exposure to potentially traumatizing events and PTSD were regressed on pain severity at the initial session and at follow up in a set of multiple regression analysis. Results : The participants reported exposure to an average of four potentially traumatizing events, and 32% had PTSD. Exposure to intentional traumatic events and PTSD were significantly associated with more severe pain, and PTSD significantly moderated the relationship between trauma exposure and pain (all p < .05). The treatment programme reduced pain moderately, an effect that was unrelated to trauma exposure and PTSD. Conclusions : Trauma exposure is related to chronic pain in the same pattern as to mental disorders, with intentional trauma being most strongly related to pain severity. PTSD moderated the relationship between trauma exposure and pain. While pain patients with PTSD initially report more pain, they responded equally to specialist pain treatment as persons without PTSD.

  7. Which factors influence the development of post-traumatic stress disorder in patients with burn injuries? A systematic review of the literature.

    Hobbs, Katherine

    2015-05-01

    This article aims to discover which variables influence the development of post-traumatic stress disorder in patients with burn injuries. It will also consider whether it is possible to predict which burns patients will develop PTSD. Post-traumatic stress disorder is an important psychopathology for burned patients as it can affect both physical outcomes and quality of life for those affected. Research states that PTSD may be identified in up to 30% of burns patients, making it relatively common. A systematic review of the literature was carried out using four databases. Eleven articles were identified from these searches, and were then analysed thematically to draw out common ideas. Gender, extraversion and neuroticism, attribution of blame, capacity for forgiveness, the event as a disaster or non-disaster, alcohol consumption and peri-traumatic emotional response were all found to influence burns patients' risk of developing PTSD. While it is possible to identify the factors that put burns patients are greater risk of developing PTSD, it is not possible to accurately predict who will go on to develop PTSD due to the interplay between variables and individual differences. Focus should instead be on screening for PTSD and timely recognition of intrusive symptoms. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Hospital admissions related to burn injury reach 40,000 annually. Patients who experience extensive burns require longer hospital stays and are at increased risk for infection and hospital acquired conditions. This comparative case study is a two patient matched case control design that follows the hospital course of two children who experienced burn injuries. For one of these patients, with the consent of the child's parents, the grandmother treated her granddaughter with essential oils. Essential oils have the potential to inhibit microbial growth, support treatment of wounds, and facilitate healing. However, there have been no large scale studies on essential oils. Data for the two cases were retrieved from the electronic medical record at a Midwestern Pediatric Hospital. Retrieved data included burn site description, treatment for burns, number of days on the ventilator, white blood cell count, length of hospital stay, number of ICU days, infections diagnosed by positive culture and pain ratings. While the goals for treatment were the same for both children, the child who received only standard care was diagnosed with two blood stream infections and four hospital acquired conditions while the child who received supplemental treatment with essential oils did not develop any blood stream infections, was diagnosed with one hospital acquired condition, was in the PICU one day less, and had a four day shorter length of hospital stay. While these case findings are intriguing, research is needed to expand understanding of the role of essential oils in the treatment of burns. Copyright © 2017 Elsevier Inc. All rights reserved.

    Based on growing findings of brain volume loss and deleterious white matter alterations during the chronic stages of injury, researchers posit that moderate-severe traumatic brain injury (TBI) may act to “age” the brain by reducing reserve capacity and inducing neurodegeneration. Evidence that these changes correlate with poorer cognitive and functional outcomes corroborates this progressive characterization of chronic TBI.

    Objective To evaluate the risk of chronic traumatic brain injury from amateur boxing. Setting Secondary research performed by combination of sport physicians and clinical academics. Design, data sources, and methods Systematic review of observational studies in which chronic traumatic brain injury was defined as any abnormality on clinical neurological examination, psychometric testing, neuroimaging studies, and electroencephalography. Studies were identified through database (1950 to date) and bibliographic searches without language restrictions. Two reviewers extracted study characteristics, quality, and data, with adherence to a protocol developed from a widely recommended method for systematic review of observational studies (MOOSE). Results 36 papers had relevant extractable data (from a detailed evaluation of 93 studies of 943 identified from the initial search). Quality of evidence was generally poor. The best quality studies were those with a cohort design and those that used psychometric tests. These yielded the most negative results: only four of 17 (24%) better quality studies found any indication of chronic traumatic brain injury in a minority of boxers studied. Conclusion There is no strong evidence to associate chronic traumatic brain injury with amateur boxing. PMID:17916811

  14. Psychiatric comorbidity of chronic daily headache: focus on traumatic experiences in childhood, post-traumatic stress disorder and suicidality.

    Juang, Kai Dih; Yang, Chin-Yi

    2014-04-01

    The fifth edition of the Diagnostic and Statistic Manual (DSM-5) reclassified some mental disorders recently. Post-traumatic stress disorder (PTSD) is in a new section termed "trauma- and stressor-related disorder". Community-based studies have shown that PTSD is associated with a notably high suicidal risk. In addition to previous findings of comorbidity between chronic daily headache (CDH) and both depressive disorders and anxiety disorders, recent data suggest that frequency of childhood maltreatment, PTSD, and suicidality are also increased in CDH. CDH patients with migraine aura are especially at risk of suicidal ideation. Research suggests that migraine attack, aura, frequency, and chronicity may all be related to serotonergic dysfunction. Vulnerability to PTSD and suicidality are also linked to brain serotonin function, including polymorphisms in the serotonin transporter gene (5-HTTLPR). In the present review, we focus on recent advances in knowledge of traumatic experiences in childhood, PTSD, and suicidality in relation to migraine and CDH. We hypothesize that vulnerability to PTSD is associated with migraine attack, migraine aura, and CDH. We further postulate that these associations may explain some of the elevated suicidal risks among patients with migraine, migraine aura, and/or CDH. Field studies are required to support these hypotheses.

    The long-term consequences of repetitive head impacts have been described since the early 20th century. Terms such as punch drunk and dementia pugilistica were first used to describe the clinical syndromes experienced by boxers. A more generic designation, chronic traumatic encephalopathy (CTE), has been employed since the mid-1900s and has been used in recent years to describe a neurodegenerative disease found not just in boxers but in American football players, other contact sport athletes, military veterans, and others with histories of repetitive brain trauma, including concussions and subconcussive trauma. This article reviews the literature of the clinical manifestations of CTE from 202 published cases. The clinical features include impairments in mood (for example, depression and hopelessness), behavior (for example, explosivity and violence), cognition (for example, impaired memory, executive functioning, attention, and dementia), and, less commonly, motor functioning (for example, parkinsonism, ataxia, and dysarthria). We present proposed research criteria for traumatic encephalopathy syndrome (TES) which consist of four variants or subtypes (TES behavioral/mood variant, TES cognitive variant, TES mixed variant, and TES dementia) as well as classifications of 'probable CTE' and 'possible CTE'. These proposed criteria are expected to be modified and updated as new research findings become available. They are not meant to be used for a clinical diagnosis. Rather, they should be viewed as research criteria that can be employed in studies of the underlying causes, risk factors, differential diagnosis, prevention, and treatment of CTE and related disorders.

    On April 3 and 5 of 2005, approximately 52,000 people gathered in Chapel Hill, North Carolina to celebrate the National Collegiate Athletic Association Final Four victories of the University of North Carolina men's basketball team. As crowds rejoiced and intensified into a celebratory riot, many participants lit dozens of bonfires and expressed themselves by jumping through the flames. To describe the interesting injury mechanism of celebratory fire jumping and to describe the injuries associated with two celebratory riots. We conducted a cross-sectional study analyzing all Emergency Medical Services (EMS) and hospital reports of injuries associated with each gathering. We used a standardized data collection instrument to record descriptive information on all patients with celebration-associated complaints and noted their treatment and disposition. For analysis, we abstracted data and generated basic descriptive statistics and comparisons of groups. A total of 58 celebrants received medical care, including 27 patients first evaluated by EMS and 49 patients subsequently evaluated in the Emergency Department. Most were young (average age = 23.8 years), male (65%, 32/49), had complaints associated with alcohol (65%, 32/49), and were not admitted to the hospital (92%, 45/49). Of those presenting for hospital evaluation, 30% (15/49) had burns associated with fire-jumping. Most patients from these gatherings had relatively minor injuries or medical complaints. However, burns associated with fire-jumping represented a substantial proportion of more serious injuries and hospitalizations. These cases are presented to increase awareness of the burn injuries associated with this type of celebratory mass gathering. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    The current study examined occurrence and within-family associations of traumatic stress reactions after child burn injury, while in the same model addressing the role of parents' own symptoms in their reports of child symptoms. One-hundred children (8-18 years old), and their mothers (n=90) and fathers (n=74) were assessed within the first month (T1) and three months (T2) after burn. Parents and children rated child traumatic stress reactions on the Children's Responses to Trauma Inventory (CRTI) and parents rated their own reactions on the Impact of Event Scale (IES). Cross-sectional associations at the two occasions were examined using a structural equation model. Occurrence of traumatic stress symptoms in the clinical range was higher in parents (T1: 24-50%; T2: 14-31%) than children (T1: 0-11%; T2: 3-5%, depending on whether children, mothers or fathers reported on symptoms). Traumatic stress symptoms of mothers at T1 and of both parents at T2 were significantly related to child self-reported symptoms. Moreover, mothers who experienced higher stress symptoms themselves gave higher ratings of their child's symptoms at both time points, while for fathers, this was only found at T2. The current study demonstrates the impact of pediatric burn injury on the family level, and shows simultaneous existence of within-family interrelatedness of traumatic stress and an influence of parents' own symptoms on their perception of child symptoms. Findings highlight the need for trauma symptom screening in all family members and for considering informants' symptoms to understand the child's functioning in particular.

    Chronic neuropathic pain after burn injury may have multiple causes, such as direct nerve injury, nerve compression, or neuroma formation, and can significantly impair quality of life and limit functional recovery. Management includes a team-based approach that involves close collaboration between occupational and physical therapists, plastic surgeons, and experts in chronic pain, from neurology, anesthesia, psychiatry, and physiatry. Carefully selected patients with an anatomic cause of chronic neuropathic pain unequivocally benefit from surgical intervention. Self-reflection and analysis yield improvement in both efficiency and effectiveness when managing patients with burns with chronic neuropathic pain. Copyright © 2017 Elsevier Inc.

    Explosive aggressive behaviour is a significant clinical and medico-legal problem in patients suffering from head injury. However, experts in neuropsychiatry have proposed a specific category for this disorder: the o rganic aggressive syndrome: . The basic reason for proposing this diagnosis is that it describes the specificity of the violent conduct secondary to 'brain damage' with greater precision. Early diagnosis and treatment of the injury is critical. The impact of hnetium-99m-hexamethylpropuleneamine oxime (HMPAO) was examined for measuring brain damage in correlation to neuropsychological performance in patients with traumatic brain injury (TBI). We thus report the case of a twelve-year-old child with a history of CET, who presents with serious episodes of heteroaggressiveness and suggest the usefulness of single photon emission computerized tomography (SPECT) to establish the validity of this psychiatric diagnosis. The appearance of modern functional neuro-image techniques (SPECT) may help to increase the validity of clinical diagnoses in the field of psychiatry in general and of forensic psychiatry in particularly, as the related findings may be used as demarcation criteria to establish syndromic diagnoses (Au)

    Complete olecranon bursectomy with debridement, protection of veins and nerves. Risk-adapted antibiotic therapy and early functional aftercare. Acute, traumatic laceration of the bursa olecrani, chronic therapy-resistant bursitis olecrani. For traumatic bursa injuries: general contraindications for anesthesia and surgery; chronic bursitis: initially not closable skin defect (plastic surgery required), hemodynamically instable patient (e.g. systemic inflammatory response syndrome [SIRS] or sepsis), pre-existing skin infection. Local anesthesia beyond the lesion, careful debridement, identification and removal of the entire bursa, excision of contaminated skin, lavage, drain insertion (Redon, Easy-flow, Penrose). Wound closure, elastic bandage, and splint. Elastic bandage for 2 days, followed by drain removal. Wound assessment, early functional aftercare without splint, antibiotic therapy in septic bursitis for 2 weeks, PRICE scheme. Removal of stitches after 10-12 days. Over 5 years, 138 cases of traumatic bursa lesion or chronic bursitis olecrani were treated in our clinic, 82 patients underwent surgery. Ten patients were treated with vacuum-assisted closure therapy and consecutive wound healing; fistulae occurred in two patients and in another two dehiscence developed. All of the defects could be closed without flaps.

Practice is heavily influenced by anecdote rather than evidence-based protocols and industry-biased literature rather than robust randomized controlled trials. Burn units are well placed to address this considerable need, as a result of their infrastructure, their multispecialty staffing, and their need to evolve in light of the declining incidence of major burn injury in developed countries. The aim of this review is to evaluate some of the ideological and practical challenges facing wound practitioners and burn surgeons while managing chronic and complex wounds. It also includes an approach to wound assessment and how to conceptualize and implement dressing strategies and new and existing multimodal therapies.

  12. Considerations for Experimental Animal Models of Concussion, Traumatic Brain Injury, and Chronic Traumatic Encephalopathy—These Matters Matter

    Directory of Open Access Journals (Sweden)

    Mark W. Wojnarowicz

    2017-06-01

    Full Text Available Animal models of concussion, traumatic brain injury (TBI, and chronic traumatic encephalopathy (CTE are widely available and routinely deployed in laboratories around the world. Effective animal modeling requires careful consideration of four basic principles. First, animal model use must be guided by clarity of definitions regarding the human disease or condition being modeled. Concussion, TBI, and CTE represent distinct clinical entities that require clear differentiation: concussion is a neurological syndrome, TBI is a neurological event, and CTE is a neurological disease. While these conditions are all associated with head injury, the pathophysiology, clinical course, and medical management of each are distinct. Investigators who use animal models of these conditions must take into account these clinical distinctions to avoid misinterpretation of results and category mistakes. Second, model selection must be grounded by clarity of purpose with respect to experimental questions and frame of reference of the investigation. Distinguishing injury context (“inputs” from injury consequences (“outputs” may be helpful during animal model selection, experimental design and execution, and interpretation of results. Vigilance is required to rout out, or rigorously control for, model artifacts with potential to interfere with primary endpoints. The widespread use of anesthetics in many animal models illustrates the many ways that model artifacts can confound preclinical results. Third, concordance between key features of the animal model and the human disease or condition being modeled is required to confirm model biofidelity. Fourth, experimental results observed in animals must be confirmed in human subjects for model validation. Adherence to these principles serves as a bulwark against flawed interpretation of results, study replication failure, and confusion in the field. Implementing these principles will advance basic science discovery and

    In the chronic phase after mild traumatic brain injury (mTBI), microhaemorrhages are frequently detected on magnetic resonance imaging (MRI). It is however unclear whether microhaemorrhages are associated with functional outcome and which MRI sequence is most appropriate to address this association. We aimed to determine the association between microhaemorrhages and functional outcome in the chronic posttraumatic phase after injury with the most suitable MRI sequence to address this association. One hundred twenty-seven patients classified with mTBI admitted to the outpatient clinic from 2008 to 2015 for persisting posttraumatic complaints were stratified according to the presence of MRI abnormalities (n = 63 (MRI+ group) and n = 64 without abnormalities (MRI- group)). For the detection of microhaemorrhages, susceptibility-weighted imaging (SWI) and T2* gradient recalled echo (T2*GRE) were used. The relation between the functional outcome (dichotomized Glasgow Outcome Scale Extended scores) and the number and localization of microhaemorrhages was analysed using binary logistic regression. SWI detected twice as many microhaemorrhages compared to T2*GRE: 341 vs. 179. Lesions were predominantly present in the frontal and temporal lobes. Unfavourable outcome was present in 67% of the MRI+ group with a significant association of total number of microhaemorrhages in the temporal cortical area on SWI (OR 0.43 (0.21-0.90) p = 0.02), with an explained variance of 44%. The number of microhaemorrhages was not correlated with the number of posttraumatic complaints. An unfavourable outcome in the chronic posttraumatic phase is associated with the presence and number of microhaemorrhages in the temporal cortical area. SWI is preferably used to detect these microhaemorrhages. (orig.)

  14. Chronic Traumatic Encephalopathy: Is Latency in Symptom Onset Explained by Tau Propagation?

    Science.gov (United States)

    Kriegel, Joshua; Papadopoulos, Zachary; McKee, Ann C

    2018-02-01

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy associated with repetitive mild brain trauma. CTE, previously termed "dementia pugilistica," has been identified in American football, ice hockey, baseball, rugby and soccer players, boxers, wrestlers, and military personnel exposed to blast and other traumatic brain injuries. There is often a long latency period between an individual's exposure to repetitive brain trauma and the clinical symptoms of CTE. The pathology of CTE is characterized by a progression from isolated focal perivascular hyperphosphorylated tau lesions in the cerebral cortex to a widespread tauopathy that involves diffuse cortical and medial temporal lobe regions. We hypothesize that the spread of tau from focal perivascular lesions to a widespread tauopathy occurs as a result of intraneuronal and intrasynaptic prion-like protein templating, as well as tau secretion and propagation along glymphatic and cerebrospinal fluid pathways.

This ritual entails not only immediate complications such as infection, pain, and haemorrhage, but also chronic ones including dysmenorrhea and dyspareunia. However, there is limited data on neuropathic pain secondary to female genital mutilation when searching the literature. Case. This case discusses a 38-year-old female with a history of infibulation who presented with a chronic burning abdominal and anterior vulvar pain including the related investigations and treatment. Discussion. This case brings to light the additional delayed complication of this ritual: sensory neuropathy. Our goal is to educate health professionals to be aware of these complications and to appropriately investigate and treat them in order to find a solution to relieve the patients’ symptoms.

    To explore the prevalence and determinants of chronic post-traumatic stress disorder (PTSD) among flood victims. A cross-sectional survey was carried out in 2014 among individuals who had experienced the 1998 floods and had been diagnosed with PTSD in 1999 in Hunan, China. Cluster sampling was used to select subjects from the areas that had been surveyed in 1999. PTSD was diagnosed according to DSM-IV criteria, social support was measured according to a Social Support Rating Scale, coping style was measured according to a Simplified Coping Style Questionnaire, and personality was measured by use of the revised Eysenck Personality Questionnaire Short Scale for Chinese. Data were collected through face-to-face interviews by use of a structured questionnaire. Multivariate logistic regression analysis was used to reveal the determinants of chronic PTSD. A total of 123 subjects were interviewed, 17 of whom (14.4%) were diagnosed with chronic PTSD. Chronic PTSD was significantly associated with disaster stressors (odds ratio [OR]: 1.74; 95% confidence interval [CI]: 1.22-2.47), nervousness (OR: 1.09; 95% CI: 1.01-1.17), and social support (OR: 0.85; 95 CI%: 0.74-0.98). Chronic PTSD in flood victims is significantly associated with disaster stressors, nervousness, and social support. These factors may play important roles in identifying persons at high risk of chronic PTSD.

    This study conducted a preliminary examination on cognitive reserve (CR) as a modifier of symptom expression in subjects with autopsy-confirmed chronic traumatic encephalopathy (CTE). The sample included 25 former professional football players neuropathologically diagnosed with CTE stage III or IV. Next of kin interviews ascertained age at cognitive and behavioral/mood symptom onset and demographic/athletic characteristics. Years of education and occupational attainment defined CR. High occupational achievement predicted later age at cognitive (p=0.02) and behavioral/mood (p=0.02) onset. Education was not an individual predictor. These preliminary findings suggest that CR may forestall the clinical manifestation of CTE.

    The relationship between soccer and chronic traumatic encephalopathy (CTE) is not well established. We report clinicopathological correlations in an 83-year-old retired center-back soccer player, with no history of concussion, manifesting typical Alzheimer-type dementia. Examination revealed mixed pathology including widespread CTE, moderate Alzheimer's disease, hippocampal sclerosis, and TDP-43 proteinopathy. This case adds to a few CTE cases described in soccer players. Furthermore, it corroborates that CTE may present clinically as typical Alzheimer-type dementia. Further studies investigating the extent to which soccer is a risk for CTE are needed.

  20. Damage to Myelin and Oligodendrocytes: A Role in Chronic Outcomes Following Traumatic Brain Injury?

    Directory of Open Access Journals (Sweden)

    William L. Maxwell

    2013-09-01

    Full Text Available There is increasing evidence in the experimental and clinical traumatic brain injury (TBI literature that loss of central myelinated nerve fibers continues over the chronic post-traumatic phase after injury. However, the biomechanism(s of continued loss of axons is obscure. Stretch-injury to optic nerve fibers in adult guinea-pigs was used to test the hypothesis that damage to the myelin sheath and oligodendrocytes of the optic nerve fibers may contribute to, or facilitate, the continuance of axonal loss. Myelin dislocations occur within internodal myelin of larger axons within 1–2 h of TBI. The myelin dislocations contain elevated levels of free calcium. The volume of myelin dislocations increase with greater survival and are associated with disruption of the axonal cytoskeleton leading to secondary axotomy. Waves of Ca2+ depolarization or spreading depression extend from the initial locus injury for perhaps hundreds of microns after TBI. As astrocytes and oligodendrocytes are connected via gap junctions, it is hypothesized that spreading depression results in depolarization of central glia, disrupt axonal ionic homeostasis, injure axonal mitochondria and allow the onset of axonal degeneration throughout an increasing volume of brain tissue; and contribute toward post-traumatic continued loss of white matter.

    The relationship between post-traumatic stress disorder (PTSD) and chronic symptoms of mild traumatic brain injury (mTBI) is difficult to discern and poorly understood. An accurate differential diagnosis, assessment, and treatment of mTBI and PTSD are challenging due to significant symptom overlap and the absence of clearly established biomarkers. The objective of this work is to examine how post-traumatic stress influences task-free default mode network in chronic mTBI subjects. Control subjects (N = 44) were compared with chronic mTBI subjects with low (N = 58, PTSD Checklist-Civilian Version [PCL-C] total network of brain regions involved with emotional regulation and memory coding, rather than a fear-related response. Taken together, the results suggest these regions form a network that could be a target for future research pertaining to PTSD and chronic mTBI. Furthermore, the use of clinical measures, task-based imaging studies, or multimodal imaging could help further elucidate specific neural correlates of PTSS and mTBI.

    A large body of literature supports the role of psychologic stress in urticaria; however, the comorbidity between chronic idiopathic urticaria (CIU) and post-traumatic stress disorder (PTSD), a classic stress-mediated syndrome, has received little attention. The underlying etiology of urticaria is not identifiable in about 70% of patients, possibly because of difficulties with identification of a direct cause-and-effect relationship between a potential causative factor and the onset of urticaria. The core features of PTSD (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision [DSMIV-TR]) that are important in urticaria include (1) autonomic nervous system reactivity and state of sympathetic hyperarousal that can manifest as CIU, and (2) the persistent re-experiencing of the traumatic events in PTSD, which can manifest as urticaria or angioedema, or both, affecting a previously traumatized body region (eg, urticarial wheals affecting the body region where the patient had been stabbed years earlier). The following features of PTSD make it difficult to use the cause-and-effect model for the determination of causation: (1) PTSD may first emerge years after the initial trauma and is classified as PTSD with Delayed Onset (DSMIV-TR); and (2) the traumatic triggers that precipitate the PTSD symptoms may be unique and idiosyncratic to the patient and not even qualify as stressful or traumatic by standard criteria (eg, precipitating events for the PTSD may include smell of a certain cologne that was used by the perpetrator or witnessing a scene in a movie that was reminiscent of the location where the abuse occurred). Finally, in PTSD with Delayed Onset, patients may not make a conscious association between their recurrent urticaria and their earlier traumas because they can develop classically conditioned associations between stimuli that are reminiscent of the original abuse situation and their somatic reactions such as urticaria.

    Following his discovery of chronic traumatic encephalopathy (CTE) in football players in 2002, Dr. Bennet Omalu hypothesized that posttraumatic stress disorder (PTSD) in military veterans may belong to the CTE spectrum of diseases. The CTE surveillance at the Brain Injury Research Institute was therefore expanded to include deceased military veterans diagnosed with PTSD. The authors report the case of a 27-year-old United States Marine Corps (USMC) Iraqi war veteran, an amphibious assault vehicle crewman, who committed suicide by hanging after two deployments to Fallujah and Ramadi. He experienced combat and was exposed to mortar blasts and improvised explosive device blasts less than 50 m away. Following his second deployment he developed a progressive history of cognitive impairment, impaired memory, behavioral and mood disorders, and alcohol abuse. Neuropsychiatric assessment revealed a diagnosis of PTSD with hyperarousal (irritability and insomnia) and numbing. He committed suicide approximately 8 months after his honorable discharge from the USMC. His brain at autopsy appeared grossly unremarkable except for congestive brain swelling. There was no atrophy or remote focal traumatic brain injury such as contusional necrosis or hemorrhage. Histochemical and immunohistochemical brain tissue analysis revealed CTE changes comprising multifocal, neocortical, and subcortical neurofibrillary tangles and neuritic threads (ranging from none, to sparse, to frequent) with the skip phenomenon, accentuated in the depths of sulci and in the frontal cortex. The subcortical white matter showed mild rarefaction, sparse perivascular and neuropil infiltration by histiocytes, and mild fibrillary astrogliosis. Apolipoprotein E genotype was 3/4. The authors report this case as a sentinel case of CTE in an Iraqi war veteran diagnosed with PTSD to possibly stimulate new lines of thought and research in the possible pathoetiology and pathogenesis of PTSD in military veterans as part of

    Chronic traumatic encephalopathy (CTE) has been linked to participation in contact sports such as boxing and American football. CTE results in a progressive decline of memory and cognition, as well as depression, suicidal behavior, poor impulse control, aggressiveness, parkinsonism, and, eventually, dementia. In some individuals, it is associated with motor neuron disease, referred to as chronic traumatic encephalomyelopathy, which appears clinically similar to amyotrophic lateral sclerosis. Results of neuropathologic research has shown that CTE may be more common in former contact sports athletes than previously believed. It is believed that repetitive brain trauma, with or possibly without symptomatic concussion, is responsible for neurodegenerative changes highlighted by accumulations of hyperphosphorylated tau and TDP-43 proteins. Given the millions of youth, high school, collegiate, and professional athletes participating in contact sports that involve repetitive brain trauma, as well as military personnel exposed to repeated brain trauma from blast and other injuries in the military, CTE represents an important public health issue. Focused and intensive study of the risk factors and in vivo diagnosis of CTE will potentially allow for methods to prevent and treat these diseases. Research also will provide policy makers with the scientific knowledge to make appropriate guidelines regarding the prevention and treatment of brain trauma in all levels of athletic involvement as well as the military theater.

    Since the 1920s, it has been known that the repetitive brain trauma associated with boxing may produce a progressive neurological deterioration, originally termed dementia pugilistica, and more recently, chronic traumatic encephalopathy (CTE). We review 48 cases of neuropathologically verified CTE recorded in the literature and document the detailed findings of CTE in 3 profession althletes, 1 football player and 2 boxers. Clinically, CTE is associated with memory disturbances, behavioral and personality changes, parkinsonism, and speech and gait abnormalities. Neuropathologically, CTE is characterized by atrophy of the cerebral hemispheres, medial temporal lobe, thalamus, mammillary bodies, and brainstem, with ventricular dilatation and a fenestrated cavum septum pellucidum. Microscopically, there are extensive tau-immunoreactive neurofibrillary tangles, astrocytic tangles, and spindle-shaped and threadlike neurites throughout the brain. The neurofibrillary degeneration of CTE is distinguished from other tauopathies by preferential involvement of the superficial cortical layers, irregular patchy distribution in the frontal and temporal cortices, propensity for sulcal depths, prominent perivascular, periventricular, and subpial distribution, and marked accumulation of tau-immunoreactive astrocytes. Deposition of beta-amyloid, most commonly as diffuse plaques, occurs in fewer than half the cases. Chronic traumatic encephalopathy is a neuropathologically distinct slowly progressive tauopathy with a clear environmental etiology.

    Few neurologic diseases have captured the nation's attention more completely than chronic traumatic encephalopathy (CTE), which has been discovered in the autopsies of professional athletes, most notably professional football players. The tragic case of Junior Seau, a Hall of Fame, National Football League linebacker, has been the most high-profile confirmed case of CTE. Here we describe Seau's case, which concludes an autopsy conducted at the National Institutes of Health that confirmed the diagnosis. Since 1990, Junior Seau had a highly distinguished 20-year career playing for the National Football League as a linebacker, from which he sustained multiple concussions. He committed suicide on May 2, 2012, at age 43, after which an autopsy confirmed a diagnosis of CTE. His clinical history was significant for a series of behavioral disturbances. Seau's history and neuropathologic findings were used to better understand the pathophysiology, diagnosis, and possible risk factors for CTE. This high-profile case reflects an increasing awareness of CTE as a long-term consequence of multiple traumatic brain injuries. The previously unforeseen neurologic risks of American football have begun to cast doubt on the safety of the sport. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Objective : Biological dressings like collagen are impermeable to bacteria, and create the most physiological interface between the wound surface and the environment. Collagen dressings have other advantages over conventional dressings in terms of ease of application and being natural, non-immunogenic, non-pyrogenic, hypo-allergenic, and pain-free. This study aims to compare the efficacy of collagen dressing in treating burn and chronic wounds with that of conventional dressing materials. Materials and Methods : The records of 120 patients with chronic wounds of varied aetiologies and with mean age 43.7 years were collected and analyzed. The patients had been treated either with collagen or other conventional dressing materials including silver sulfadiazine, nadifloxacin, povidone iodine, or honey (traditional dressing material. Patients with co-morbidities that could grossly affect the wound healing like uncontrolled diabetes mellitus, chronic liver or renal disease, or major nutritional deprivation were not included. For the purpose of comparison the patients were divided into two groups; ′Collagen group′ and ′Conventional group′, each having 60 patients. For assessment the wound characteristics (size, edge, floor, slough, granulation tissue, and wound swab or pus culture sensitivity results were recorded. With start of treatment, appearance of granulation tissue, completeness of healing, need for skin grafting, and patients′ satisfaction was noted for each patient in both groups. Results : With two weeks of treatment, 60% of the ′collagen group′ wounds and only 42% of the ′conventional group′ wounds were sterile (P=0.03. Healthy granulation tissue appeared earlier over collagen-dressed wounds than over conventionally treated wounds (P=0.03.

    This study investigated secondary traumatic stress and its relationship to burnout among nurses working at a Turkish hospital. A mixed-methods design included a cross-sectional survey administering the Professional Quality of Life instrument and Maslach Burnout Inventory to 106 nurses. Interviews with a subgroup of eight participants explored nurses' experiences and coping strategies related to caring for chronically ill pediatric patients. High risk levels of secondary traumatic stress existed among 40.6% participants, and those over the age of 40 years were at greater risk. Two main interview themes emerged that identified (a) consequences and (b) coping strategies while caring for chronically ill children. Nurses experience emotional burdens and may purposefully distance themselves from chronically ill children. Social support from nurse colleagues and spiritual beliefs assist coping. Workplaces should acknowledge stressors inherent in chronic pediatric nursing care. Environments that welcome spiritual practices and actively encourage social support could address job hazards.

    Chronic traumatic encephalopathy (CTE) is a neuropathologically defined disease reportedly linked to a history of repetitive brain trauma. As such, retired collision sport athletes are likely at heightened risk for developing CTE. Researchers have described distinct pathological features of CTE as well a wide range of clinical symptom presentations, recently termed traumatic encephalopathy syndrome (TES). These clinical symptoms are highly variable, non-specific to individuals described as having CTE pathology in case reports, and are often associated with many other factors. This review describes the cognitive, emotional, and behavioral changes associated with 1) developmental and demographic factors, 2) neurodevelopmental disorders, 3) normal aging, 4) adjusting to retirement, 5) drug and alcohol abuse, 6) surgeries and anesthesia, and 7) sleep difficulties, as well as the relationship between these factors and risk for developing dementia-related neurodegenerative disease. We discuss why some professional athletes may be particularly susceptible to many of these effects and the importance of choosing appropriate controls groups when designing research protocols. We conclude that these factors should be considered as modifiers predominantly of the clinical outcomes associated with repetitive brain trauma within a broader biopsychosocial framework when interpreting and attributing symptom development, though also note potential effects on neuropathological outcomes. Importantly, this could have significant treatment implications for improving quality of life. PMID:27561662

    Chronic traumatic encephalopathy (CTE, previously called punch drunk and dementia pugilistica) has a rich history in the medical literature in association with boxing, but has only recently been recognized with other contact sports, such as football and ice hockey, as well as with military blast injuries. CTE is thought to be a neurodegenerative disease associated with repeated concussive and subconcussive blows to the head. There is characteristic gross and microscopic pathology found in the brain, including frontal and temporal atrophy, axonal degeneration, and hyperphosphorylated tau and TAR DNA-binding protein 43 pathology. Clinically, there are characteristic progressive deficits in cognition (memory, executive dysfunction), behavior (explosivity, aggression), mood (depression, suicidality), and motor function (parkinsonism), which correlate with the anatomic distribution of brain pathology. While CTE shares clinical and neuropathological traits with other neurodegenerative diseases, the clinical syndrome and the neuropathology as a whole are distinct from other neurodegenerative diseases. Here we review the CTE literature to date. We also draw on the literature from mild traumatic brain injury and other neurodegenerative dementias, particularly when these studies provide guidance for future CTE research. We conclude by suggesting seven essential areas for future CTE research.

    Less than eight years after the establishment of the National Child Traumatic Stress Network in 2001 it has become evident that the current diagnostic classification system is inadequate for tens of thousands of traumatized children. While the inclusion of PTSD in the psychiatric classification system in 1980 led to extensive scientific studies of that diagnosis, over the past 25 years there has been a parallel emergence of the field of Developmental Psychopathology, which has documented the effects of interpersonal trauma and disruption of caregiving systems on the development of affect regulation, attention, cognition, perception, and interpersonal relationships. Another significant development has been the increasing documentation of the effects of adverse early life experiences on brain development. The goal of introducing the diagnosis of Developmental Trauma Disorder is to capture the reality of the clinical presentations of children and adolescents exposed to chronic interpersonal trauma. Whether or not they exhibit some symptoms of PTSD, children who have developed in the context of ongoing danger, maltreatment, and inadequate caregiving systems are ill-served by the current diagnostic system, as it frequently leads to multiple unrelated diagnoses, an emphasis on behavioral control without recognition of interpersonal trauma and lack of safety in the etiology of symptoms, and a lack of attention to ameliorating the developmental disruptions that underlie the symptoms.

    Chronic traumatic encephalopathy (CTE) is an acquired primary tauopathy with a variety of cognitive, behavioral, and motor symptoms linked to cumulative brain damage sustained from single, episodic, or repetitive traumatic brain injury (TBI). No definitive clinical diagnosis for this condition exists. In this work, we used [F-18]FDDNP PET to detect brain patterns of neuropathology distribution in retired professional American football players with suspected CTE (n = 14) and compared results with those of cognitively intact controls (n = 28) and patients with Alzheimer's dementia (AD) (n = 24), a disease that has been cognitively associated with CTE. [F-18]FDDNP PET imaging results in the retired players suggested the presence of neuropathological patterns consistent with models of concussion wherein brainstem white matter tracts undergo early axonal damage and cumulative axonal injuries along subcortical, limbic, and cortical brain circuitries supporting mood, emotions, and behavior. This deposition pattern is distinctively different from the progressive pattern of neuropathology [paired helical filament (PHF)-tau and amyloid-β] in AD, which typically begins in the medial temporal lobe progressing along the cortical default mode network, with no or minimal involvement of subcortical structures. This particular [F-18]FDDNP PET imaging pattern in cases of suspected CTE also is primarily consistent with PHF-tau distribution observed at autopsy in subjects with a history of mild TBI and autopsy-confirmed diagnosis of CTE.

    Sleep quality appears to be altered by traumatic brain injury (TBI). However, whether persistent post-injury changes in sleep architecture are present is unknown and relatively unexplored. We conducted a systematic review and meta-analysis to assess the extent to which chronic TBI (>6 months since injury) is characterized by changes to sleep architecture. We also explored the relationship between sleep architecture and TBI severity. In the fourteen included studies, sleep was assessed with at least one night of polysomnography in both chronic TBI participants and controls. Statistical analyses, performed using Comprehensive Meta-Analysis software, revealed that chronic TBI is characterized by relatively increased slow wave sleep (SWS). A meta-regression showed moderate-severe TBI is associated with elevated SWS, reduced stage 2, and reduced sleep efficiency. In contrast, mild TBI was not associated with any significant alteration of sleep architecture. The present findings are consistent with the hypothesis that increased SWS after moderate-severe TBI reflects post-injury cortical reorganization and restructuring. Suggestions for future research are discussed, including adoption of common data elements in future studies to facilitate cross-study comparability, reliability, and replicability, thereby increasing the likelihood that meaningful sleep (and other) biomarkers of TBI will be identified.

    ABSTRACT Chronic traumatic encephalopathy (CTE) was initially described in boxers, but in recent years it has been reported in other settings, particularly in contact sports and military personnel. Soccer (football association) had previously been (and still is) considered relatively safe when compared to other sports, such as American football. However, a few cases of professional soccer players with CTE have been reported in the last few years. It is still unknown how frequent this condition is in soccer players, and the role played by heading the ball remains elusive. Other traumas to the head, face and neck caused by contact with another player's head, arm or other body parts are among the most frequent in soccer. In spite of the lack of more in-depth knowledge, there is reasonable evidence for recommending severe punishment (red card and suspension for several matches) for players causing avoidable trauma to another player's head.

    Blast exposure is associated with traumatic brain injury (TBI), neuropsychiatric symptoms, and long-term cognitive disability. We examined a case series of postmortem brains from U.S. military veterans exposed to blast and/or concussive injury. We found evidence of chronic traumatic encephalopathy (CTE), a tau protein–linked neurodegenerative disease, that was similar to the CTE neuropathology observed in young amateur American football players and a professional wrestler with histories of concussive injuries. We developed a blast neurotrauma mouse model that recapitulated CTE-linked neuropathology in wild-type C57BL/6 mice 2 weeks after exposure to a single blast. Blast-exposed mice demonstrated phosphorylated tauopathy, myelinated axonopathy, microvasculopathy, chronic neuroinflammation, and neurodegeneration in the absence of macroscopic tissue damage or hemorrhage. Blast exposure induced persistent hippocampal-dependent learning and memory deficits that persisted for at least 1 month and correlated with impaired axonal conduction and defective activity-dependent long-term potentiation of synaptic transmission. Intracerebral pressure recordings demonstrated that shock waves traversed the mouse brain with minimal change and without thoracic contributions. Kinematic analysis revealed blast-induced head oscillation at accelerations sufficient to cause brain injury. Head immobilization during blast exposure prevented blast-induced learning and memory deficits. The contribution of blast wind to injurious head acceleration may be a primary injury mechanism leading to blast-related TBI and CTE. These results identify common pathogenic determinants leading to CTE in blast-exposed military veterans and head-injured athletes and additionally provide mechanistic evidence linking blast exposure to persistent impairments in neurophysiological function, learning, and memory.

Data Analysis: Paired Student′s t-test was used for the assessment of functional recovery using mean BI scores at admission and discharge. The Wilcoxon nonparametric test was used for the assessment of functional recovery by comparing admission and discharge DRS scores. Results: Mean duration of stay was 30.8 days (range 18--91, SD15.6. Significant functional recovery observed in patients comparing BI and DRS scores at admission and discharge (mean BI admission 50.5±25.4, range 0--85 vs. mean discharge BI score 61.1±25.3, range 0--95, P<0.001, mean DRS admission score 7.57±4.1, range 2.5--21.0 vs. mean discharge DRS score 6.36±4.3, range 1.0-21.0, P<0.001. Conclusion: Patients with severe TBI continue to show functional recovery even in chronic phase with rehabilitation. They are left with significant residual physical and cognitive deficits and would require long-term care and assistance from care givers for the daily activities, as suggested by the mean DRS score at discharge.

    During the transition from acute to chronic stages of recovery after spinal cord injury (SCI), there is an evolving state of immunologic dysfunction that exacerbates the problems associated with the more clinically obvious neurologic deficits. Since injury directly affects cells embedded within the "immune privileged/specialized" milieu of the spinal cord, maladaptive or inefficient responses are likely to occur. Collectively, these responses qualify as part of the continuum of "SCI disease" and are important therapeutic targets to improve neural repair and neurological outcome. Generic immune suppressive therapies have been largely unsuccessful, mostly because inflammation and immunity exert both beneficial (plasticity enhancing) and detrimental (e.g. glia- and neurodegenerative; secondary damage) effects and these functions change over time. Moreover, "compartimentalized" investigations, limited to only intraspinal inflammation and associated cellular or molecular changes in the spinal cord, neglect the reality that the structure and function of the CNS are influenced by systemic immune challenges and that the immune system is 'hardwired' into the nervous system. Here, we consider this interplay during the progression from acute to chronic SCI. Specifically, we survey impaired/non-resolving intraspinal inflammation and the paradox of systemic inflammatory responses in the context of ongoing chronic immune suppression and autoimmunity. The concepts of systemic inflammatory response syndrome (SIRS), compensatory anti-inflammatory response syndrome (CARS) and "neurogenic" spinal cord injury-induced immune depression syndrome (SCI-IDS) are discussed as determinants of impaired "host-defense" and trauma-induced autoimmunity.

    Traumatic brain injury (TBI) is a significant biomedical problem among military personnel and civilians. There exists an urgent need to develop and refine biological measures of acute brain injury and chronic recovery after brain injury. Such measures "biomarkers" can assist clinicians in helping to define and refine the recovery process and developing treatment paradigms for the acutely injured to reduce secondary injury processes. Recent biomarker studies in the acute phase of TBI have highlighted the importance and feasibilities of identifying clinically useful biomarkers. However, much less is known about the subacute and chronic phases of TBI. We propose here that for a complex biological problem such as TBI, multiple biomarker types might be needed to harness the wide range of pathological and systemic perturbations following injuries, including acute neuronal death, neuroinflammation, neurodegeneration and neuroregeneration to systemic responses. In terms of biomarker types, they range from brain-specific proteins, microRNA, genetic polymorphism, inflammatory cytokines and autoimmune markers and neuro-endocrine hormones. Furthermore, systems biology-driven biomarkers integration can help present a holistic approach to understanding scenarios and complexity pathways involved in brain injury.

  8. A chronic traumatic tracheoesophageal fistula functioning as a respirator and a phonator simultaneously

    Full Text Available Acquired benign tracheoesophageal fistula (TEF is an infrequent complication of prolonged intubation or chest blunt injury. Controversy exists as to whether this should be repaired in a single-stage or in a two-stage procedure. To understand the advantage of one-stage surgery on this complicated injury, and vocalization after reconstruction, we will present a case that had a chronic traumatic TEF, compounded with total laryngotracheal obstruction and an existing unilateral vocal fixation. A 28-year-old female sustained a laryngotracheal injury in a car accident eight years ago and underwent a temporary laryngotracheal stent placement after reconstructive surgery, for one year, in another hospital. Relapsing aspiration pneumonia had developed since then. Video laryngoscopy revealed a mobile right vocal fold, a completely obstructed glottic lumen by granulomatous tissue, and a TEF. This chronic fistula functioned as a respirator without any assistance from the ventilator tube placement, as also a phonator, offering a socially acceptable voice simultaneously, as the larynges were totally obstructed by the scarring granulation tissue. This surrogate glottis enabled survival without a tracheostoma and challenged the justification of any further reconstruction in this patient. Eventually, TEF repair and reconstruction of the laryngotracheal airway were conducted in one stage. Subsequently, the insufficient glottis was corrected by medialized laryngoplasty, to complete the entire reconstruction work.

    Full Text Available Chronic traumatic encephalopathy (CTE is a neurodegenerative disease associated with head trauma. Although initially believed to affect only boxers, the at-risk population has expanded to encompass a much wider demographic, including American football players, hockey players, wrestlers, and military veterans. This expansion has garnered considerable media attention and public concern for the potential neurodegenerative effects of head trauma. The main aim of this systematic review is to give a complete overview of the common findings and risk factors for CTE as well as the status quo regarding the incidence and prevalence of CTE. This systematic review was performed using PubMed and MEDLINE and includes all neuropathologically confirmed cases of CTE in the medical literature to date, from the first published case in 1954 to August 1, 2013 (n = 153. The demographics, including the primary source of mTBI (mild Traumatic Brain Injury, age and cause of death, ApoE genotype, and history of substance abuse, when listed, were obtained from each case report. The demographics of American football players found to have CTE are also presented separately in order to highlight the most prevalent group of CTE cases reported in recent years. These 153 case reports of CTE represent the largest collection to date. We found that a history of mTBI was the only risk factor consistently associated with CTE. In addition, we found no relationships between CTE and age of death or abnormal ApoE allele. Suicide and the presence of premorbid dementia was not strongly associated with CTE. We conclude that the incidence of CTE remains unknown due to the lack of large, longitudinal studies. Furthermore, the neuropathological and clinical findings related to CTE overlap with many common neurodegenerative diseases. Our review reveals significant limitations of the current CTE case reporting and questions the widespread existence of CTE in contact sports.

    Chronic traumatic encephalopathy (CTE) is a recently revived term used to describe a neurodegenerative process that occurs as a long term complication of repetitive mild traumatic brain injury (TBI). Corsellis provided one of the classic descriptions of CTE in boxers under the name "dementia pugilistica" (DP). Much recent attention has been drawn to the apparent association of CTE with contact sports (football, soccer, hockey) and with frequent battlefield exposure to blast waves generated by improvised explosive devices (IEDs). Recently, a promising serum biomarker has been identified by measurement of serum levels of the neuronal microtubule associated protein tau. New positron emission tomography (PET) ligands (e.g., [18 F] T807) that identify brain tauopathy have been successfully deployed for the in vitro and in vivo detection of presumptive tauopathy in the brains of subjects with clinically probable CTE. Major academic and lay publications on DP/CTE were reviewed beginning with the 1928 paper describing the initial use of the term CTE by Martland. The major current concepts in the neurological, psychiatric, neuropsychological, neuroimaging, and body fluid biomarker science of DP/CTE have been summarized. Newer achievements, such as serum tau and [18 F] T807 tauopathy imaging, are also introduced and their significance has been explained. Recent advances in the science of DP/CTE hold promise for elucidating a long sought accurate determination of the true prevalence of CTE. This information holds potentially important public health implications for estimating the risk of contact sports in inflicting permanent and/or progressive brain damage on children, adolescents, and adults.

    The aetiopathogenesis of chronic anal fissure (CAF) is unclear and is probably multifactorial. CAF represents 10-15% of proctological consultations. This case report identifies adulthood sexual abuse as a significant risk and a potential aetiopathogenic factor of CAF This case history was discovered while carrying out administrated interviews during authors' clinical retrospective study on CAF. The clinical presentation of this 49-year-old woman is predominated by chronic anal lesions (anal tears in the anoderm, anal sphincter hypertrophy), associated medical history as a high consumer of healthcare with very poor mental health, chronic traumatic anal sex practice history, and especially persistent recurrences of gastro-intestinal symptoms after surgery. Surgical history is summarized as: 7x spontaneous abortion; 5x fistulectomy and 3x anal abscess; 4x Bartholin's gland; 4x hypertrophy papilla ablation; 2x anal manometry, 2x fissurectomy and 1x sphincterotomy; 2x haemorrhoid; and 1x hysterectomy. These symptoms initially started and the operations in particular took place after she was married. After 26 years of sexual abuse within her marriage, the clinical diagnosis was made and was consented by this patient. A referral to a psychiatrist was evident and a long course of multidisciplinary therapy (medical, surgical, physiological and psychological approaches) seemed to be of benefit, in terms of improving the clinical symptoms. Authors suggest that physicians should suspect sexual abuse in any patient with a medical history as a high consumer of healthcare and especially when there is persistent recurrence after the lateral subcutaneous internal sphincterotomy. We recognise that the link or causality is difficult to prove and further study is probably needed to shed light on the link between sexual abuse and CAF: although in the United Kingdom, over 20.83% of the population are subject to sexual abuse. 83%.

  13. Cognitive Gains from Gist Reasoning Training in Adolescents with Chronic-Stage Traumatic Brain Injury

    Full Text Available Adolescents with traumatic brain injury (TBI typically demonstrate good recovery of previously acquired skills. However, higher-order and later emergent cognitive functions are often impaired and linked to poor outcomes in academic and social/behavioral domains. Few control trials exist that test cognitive treatment effectiveness at chronic recovery stages. The current pilot study compared the effects of two forms of cognitive training, gist reasoning (top-down versus rote memory learning (bottom-up, on ability to abstract meanings, recall facts, and utilize core executive functions (i.e., working memory, inhibition in 20 adolescents (ages 12-20 who were six months or longer post-TBI. Participants completed eight 45-minute sessions over one month. After training, the gist reasoning group (n = 10 exhibited significant improvement in ability to abstract meanings and increased fact recall. This group also showed significant generalizations to untrained executive functions of working memory and inhibition. The memory training group (n = 10 failed to show significant gains in ability to abstract meaning or on other untrained specialized executive functions, although improved fact recall approached significance. These preliminary results suggest that relatively short-term training (6 hours utilizing a top-down reasoning approach is more effective than a bottom-up rote learning approach in achieving gains in higher-order cognitive abilities in adolescents at chronic stages of TBI. These findings need to be replicated in a larger study; nonetheless, the preliminary data suggest that traditional cognitive intervention schedules need to extend to later-stage training opportunities. Chronic-stage, higher-order cognitive trainings may serve to elevate levels of cognitive performance in adolescents with TBI.

    Background: Traumatic brain injury represents a significant cause of mortality and permanent disability in the adult population. Acute subdural haematoma is one of the conditions most strongly associated with severe brain injury. Knowledge on the natural history of the illness and the outcome of patients conservatively managed may help the neurosurgeon in the decision-making process. Methods: We prospectively analysed 27 patients with age ranges 15-90 years, in whom a CT scan diagnosis of acute subdural haematoma was made, and in whom craniotomy for evacuation was not initially performed, to the neurosurgery department of Ayub Teaching Hospital Abbottabad (2008-2011). Patients with deranged bleeding profile, anticoagulant therapy, chronic liver disease, any other associated intracranial abnormalities, such as cerebral contusions, as shown on CT, were excluded from this study. All patients were followed by serial CT scans, and a neurological assessment was done. Results: There were 18 male and 9 female patients, Cerebral atrophy was present in over half of the sample. In 22 of our patients, the acute subdural haematoma resolved spontaneously, without evidence of damage to the underlying brain, as shown by CT or neurological findings. Four patients subsequently required burr hole drainage for chronic subdural haematoma. In each of these patients, haematoma thickness was greater than 10 mm. The mean delay between injury and operation in this group was 15-21 days. Among these patients 1 patient required craniotomy for haematoma removal due to neurological deterioration. Conclusion: Certain conscious patients with small acute subdural haematomas, without mass effect on CT, may be safely managed conservatively, but due to high risk of these acute subdural haematoma changing into chronic subdural haematoma these patients should be reinvestigated in case of neurological deterioration.

    A single traumatic brain injury (TBI), even when mild (ie, concussion), can cause lasting consequences. Individuals with a history of chronic (>1-year prior) mild TBI have an increased risk of mood disturbances (eg, depression, suicide). This population also has lingering sleep alterations, including poor sleep quality and changes in sleep stage proportions. Given these sleep deficits, we aimed to test whether sleep-dependent emotional memory consolidation is reduced in this population. We utilized a mild TBI group (3.7 ± 2.9 years post injury) and an uninjured (non-TBI) population. Participants viewed negative and neutral images both before and after a 12-hour period containing sleep ("Sleep" group) or an equivalent period of time spent awake ("Wake" group). Participants rated images for valence/arousal at both sessions, and memory recognition was tested at session two. The TBI group had less rapid eye movement (REM), longer REM latency, and more sleep complaints. Sleep-dependent memory consolidation of nonemotional images was present in all participants. However, consolidation of negative images was only present in the non-TBI group. A lack of differentiation between the TBI Sleep and Wake groups was due to poor performance in the sleep group and, unexpectedly, enhanced performance in the wake group. Additionally, although the non-TBI participants habituated to negative images over a waking period, the TBI participants did not. We propose disrupted sleep- and wake-dependent emotional processing contributes to poor emotional outcomes following chronic, mild TBI. This work has broad implications, as roughly one-third of the US population will sustain a mild TBI during their lifetime. © Sleep Research Society 2017.

    Post-traumatic stress disorder (PTSD) is one of the most prevalent long-term psychiatric diagnoses among survivors of severe acute respiratory syndrome (SARS). The objective of this study was to identify the predictors of chronic PTSD in SARS survivors. PTSD at 30 months after the SARS outbreak was assessed by the Structured Clinical Interview for the DSM-IV. Survivors' demographic data, medical information and psychosocial variables were collected for risk factor analysis. Multivariate logistic regression analysis showed that female gender as well as the presence of chronic medical illnesses diagnosed before the onset of SARS and avascular necrosis were independent predictors of PTSD at 30 months post-SARS. Associated factors included higher-chance external locus of control, higher functional disability and higher average pain intensity. The study of PTSD at 30 months post-SARS showed that the predictive value of acute medical variables may fade out. Our findings do not support some prior hypotheses that the use of high dose corticosteroids is protective against the development of PTSD. On the contrary, the adversity both before and after the SARS outbreak may be more important in hindering recovery from PTSD. The risk factor analysis can not only improve the detection of hidden psychiatric complications but also provide insight for the possible model of care delivery for the SARS survivors. With the complex interaction of the biopsychosocial challenges of SARS, an integrated multidisciplinary clinic setting may be a superior approach in the long-term management of complicated PTSD cases.

    Chronic traumatic encephalopathy (CTE) is a tauopathy associated with prior exposure to repetitive head impacts, such as those incurred through American football and other collision sports. Diagnosis is made through neuropathological examination. Many of the clinical features of CTE are common in the general population, with and without a history of head impact exposure, making clinical diagnosis difficult. As is now common in the diagnosis of other neurodegenerative disorders, such as Alzheimer's disease, there is a need for methods to diagnose CTE during life through objective biomarkers. The aim of this study was to examine tau-positive exosomes in plasma as a potential CTE biomarker. Subjects were 78 former National Football League (NFL) players and 16 controls. Extracellular vesicles were isolated from plasma. Fluorescent nanoparticle tracking analysis was used to determine the number of vesicles staining positive for tau. The NFL group had higher exosomal tau than the control group (p negative predictive value. Within the NFL group, higher exosomal tau was associated with worse performance on tests of memory (p = 0.0126) and psychomotor speed (p = 0.0093). These preliminary findings suggest that exosomal tau in plasma may be an accurate, noninvasive CTE biomarker.

    To explore the long-term prognosis and influence of social support and coping style of patients with post-traumatic stress disorder (PTSD) after suffering from floods. Patients suffered PTSD due to Dongting lake flood in 1998 were selected through cluster random sampling. PTSD scale civilian version (PCL-C) was used to examine and diagnose the participants in this study. PTSD was then evaluated by the social support rating scale (SSRS) and the simple coping style questionnaire (SCSQ). Among all the 120 subjects, 14(11.67%) of them were diagnosed as having PTSD. Compared with the rehabilitation group, scores on subjective support, objective support, total social support and positive coping, total of coping style from the non-rehabilitation group all appeared significant low (Pfloods while disaster experience (OR=1.626, 95%CI: 1.118-2.365) appeared as a risk factor. Chronic PTSD developed after the floods called for attention. Better social support, positive coping style could significantly improve the long-term prognosis of patients with PTSD after the floods.

    The association between exposure to head injury and increased risk of neurodegenerative disease, specifically chronic traumatic encephalopathy (CTE), is widely recognized. Historically, this was largely considered a phenomenon restricted to boxers, with more recent case series identifying further 'high risk' individuals, such as former American footballers, or military personnel. However, in all cases thus far reported, it is clear that it is the exposure to head injury which is associated with increased dementia risk, and not the circumstances or environment of exposure. As such, there is considerable potential for under-recognition of CTE in patients presenting with neurodegenerative disease, particularly where head injury exposure might have been historical and through sport. This article reviews current understanding of CTE and, via an illustrative case in rugby union, highlights the value of a detailed history on head injury and also draws attention to imaging studies in assessing patients with neurodegenerative disease. © The Author 2015.

    Chronic traumatic encephalopathy (CTE) is a form of neurodegeneration believed to result from repeated head injuries. Originally termed dementia pugilistica because of its association with boxing, the neuropathology of CTE was first described by Corsellis in 1973 in a case series of 15 retired boxers. CTE has recently been found to occur after other causes of repeated head trauma, suggesting that any repeated blows to the head, such as those that occur in American football, hockey, soccer, professional wrestling, and physical abuse, can also lead to neurodegenerative changes. These changes often include cerebral atrophy, cavum septi pellucidi with fenestrations, shrinkage of the mammillary bodies, dense tau immunoreactive inclusions (neurofibrillary tangles, glial tangles, and neuropil neurites), and, in some cases, a TDP-43 proteinopathy. In association with these pathologic changes, disordered memory and executive functioning, behavioral and personality disturbances (eg, apathy, depression, irritability, impulsiveness, suicidality), parkinsonism, and, occasionally, motor neuron disease are seen in affected individuals. No formal clinical or pathologic diagnostic criteria for CTE currently exist, but the distinctive neuropathologic profile of the disorder lends promise for future research into its prevention, diagnosis, and treatment.

    CCL11, a protein previously associated with age-associated cognitive decline, is observed to be increased in the brain and cerebrospinal fluid (CSF) in chronic traumatic encephalopathy (CTE) compared to Alzheimer's disease (AD). Using a cohort of 23 deceased American football players with neuropathologically verified CTE, 50 subjects with neuropathologically diagnosed AD, and 18 non-athlete controls, CCL11 was measured with ELISA in the dorsolateral frontal cortex (DLFC) and CSF. CCL11 levels were significantly increased in the DLFC in subjects with CTE (fold change = 1.234, p football (β = 0.426, p = 0.048) independent of age (β = -0.046, p = 0.824). Preliminary analyses of a subset of subjects with available post-mortem CSF showed a trend for increased CCL11 among individuals with CTE (p = 0.069) mirroring the increase in the DLFC. Furthermore, an association between CSF CCL11 levels and the number of years exposed to football (β = 0.685, p = 0.040) was observed independent of age (β = -0.103, p = 0.716). Finally, a receiver operating characteristic (ROC) curve analysis demonstrated CSF CCL11 accurately distinguished CTE subjects from non-athlete controls and AD subjects (AUC = 0.839, 95% CI 0.62-1.058, p = 0.028). Overall, the current findings provide preliminary evidence that CCL11 may be a novel target for future CTE biomarker studies.

    Over the past decade, athletic-related chronic traumatic encephalopathy (CTE) has garnered a great deal of attention in the popular press and, more recently, in the scientific press. With increasing frequency, sports medicine practitioners and providers are faced with questions from the parents of high school football players about CTE and the risk posed to children who participate in this or other contact or collision sports. The purpose of this review was to summarize the research on CTE in an attempt to provide some evidence-based answers to frequently asked questions in clinics from parents. Addressed are (1) the definitions of CTE and its symptoms, (2) the evidence for CTE in football, (3) abnormal tau protein, (4) the use of neuroimaging in CTE diagnosis, (5) risk for CTE, (6) CTE diagnosis in youth, (7) CTE and its relationship to suicide, and (8) contact and collision sports as a risk factor for permanent brain injury or death. © 2014 The Author(s).

    We describe a case of post-traumatic cephalalgia in a 54-year-old man with chronic right parieto-occipital headache 3 years posthead injury. At the initial presentation, his Glasgow Coma Scale (GCS) was 13/15 and CT brain revealed an acute subdural haematoma with fronto-temporal contusions. After 24 h his GCS dropped to 8/15 and subsequently he underwent a right-sided craniotomy and evacuation of the subdural haematoma and contusionectomy and intracranial pressure monitoring. To manage the cerebral oedema, the cranial bone flap was left in situ free-floating and was managed in an intensive care setting. He made good clinical recovery and 3 months postoperatively he complained of right-sided headache not relieved with medication and occipital nerve block. Three years later he underwent an exploration of the previous craniotomy scalp wound and the free-floating bone flap under the scalp was immobilised. The headache completely resolved following the procedure and is currently asymptomatic.

    This article describes the impact of the integration of a licensed clinical social worker (LCSW) with expertise in behavioral health on identification of risk factors for chronic pain in a cohort of adults with sickle cell disease. Authors conducted a retrospective chart review of all visits to the adult sickle cell center during the first six months of LCSW integration. Demographics, clinical history, and LCSW notes were reviewed. Overall, 71 patients were introduced to the LCSW; 55 percent of them had chronic pain. Patients with chronic pain were older, used opioids daily, took hydroxyurea, reported higher daily pain scores, and underwent more acute care visits and hospitalizations for pain with longer stays. Fifty-eight (81 percent) patients requested concrete social work services such as transportation and housing. Thirty-two patients (55 percent) expressed a desire for mental health counseling while receiving concrete services. Twenty-two (69 percent) of these patients self-disclosed at least one traumatic experience. In fact, a statistically significant relationship between chronic pain and a history of trauma was identified (p = 0.001). Results suggest that sickle cell patients should receive clinical social work services to assess for traumatic exposures that may influence chronic pain.

    Study Design Retrospective cohort study. Purpose Trauma is the most common cause for chronic coccygodynia. The present study aims at presenting our results after complete removal of the coccyx for refractory traumatic coccygodynia in terms of pain level, complication rates, and patients' overall satisfaction. Overview of Literature There is limited extant literature describing the success rate and complications in refractory isolated traumatic coccygodynia. Methods From January 2011 to January 2012, 10 consecutive patients with posttraumatic coccygodynia (six males and four females; mean age, 42 years) were enrolled in our study. Conservative treatment of the condition had failed in all patients. The same surgeon performed a complete coccygectomy on all patients. Postoperative outcomes included measurements of pain relief and degree of patient satisfaction with the procedure's results. Results In our selected cohort, all patients indicated complete pain relief or significant pain improvement in follow up-care and would recommend this procedure. One patient developed a subcutaneous hematoma that required surgical intervention. Conclusions Our results suggest that complete removal of the coccyx relieves pain in patients with refractory chronic traumatic coccygodyniaand is therefore a reasonable treatment option after conservative treatment failure.

    Post-traumatic stress disorder (PTSD) is a distressing condition, which is often treated with psychological therapies. Earlier versions of this review, and other meta-analyses, have found these to be effective, with trauma-focused treatments being more effective than non-trauma-focused treatments. This is an update of a Cochrane review first published in 2005 and updated in 2007. To assess the effects of psychological therapies for the treatment of adults with chronic post-traumatic stress disorder (PTSD). For this update, we searched the Cochrane Depression, Anxiety and Neurosis Group's Specialised Register (CCDANCTR-Studies and CCDANCTR-References) all years to 12th April 2013. This register contains relevant randomised controlled trials from: The Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). In addition, we handsearched the Journal of Traumatic Stress, contacted experts in the field, searched bibliographies of included studies, and performed citation searches of identified articles. Randomised controlled trials of individual trauma-focused cognitive behavioural therapy (TFCBT), eye movement desensitisation and reprocessing (EMDR), non-trauma-focused CBT (non-TFCBT), other therapies (supportive therapy, non-directive counselling, psychodynamic therapy and present-centred therapy), group TFCBT, or group non-TFCBT, compared to one another or to a waitlist or usual care group for the treatment of chronic PTSD. The primary outcome measure was the severity of clinician-rated traumatic-stress symptoms. We extracted data and entered them into Review Manager 5 software. We contacted authors to obtain missing data. Two review authors independently performed 'Risk of bias' assessments. We pooled the data where appropriate, and analysed for summary effects. We include 70 studies involving a total of 4761 participants in the review. The first primary outcome for this review was reduction in the severity of PTSD

    Full Text Available Background: Chronic traumatic encephalopathy (CTE is the term coined for the neurodegenerative disease often suspected in athletes with histories of repeated concussion and progressive dementia. Histologically, CTE is defined as a tauopathy with a distribution of tau-positive neurofibrillary tangles that is distinct from other tauopathies, and usually shows an absence of beta-amyloid deposits, in contrast to Alzheimer’s disease. Although the connection between repeated concussions and CTE-type neurodegeneration has been recently proposed, this causal relationship has not yet been firmly established. Also, the prevalence of CTE among athletes with multiple concussions is unknown. Methods: We performed a consecutive case series brain autopsy study on six retired professional football players from the Canadian Football League with histories of multiple concussions and significant neurological decline. Results: All participants had progressive neurocognitive decline prior to death; however, only 3 cases had post-mortem neuropathological findings consistent with CTE. The other 3 participants had pathological diagnoses of Alzheimer’s disease, amyotrophic lateral sclerosis and Parkinson’s disease. Moreover, the CTE cases showed co-morbid pathology of cancer, vascular disease and Alzheimer’s disease. Discussion: Our case studies highlight that not all athletes with history of repeated concussions and neurological symptomalogy present neuropathological changes of CTE. These preliminary findings support the need for further research into the link between concussion and CTE as well as the need to expand the research to other possible causes of taupathy in athletes. They point to a critical need for prospective studies with good sampling methods to allow us to understand the relationship between multiple concussions and the development of CTE.

    Chronic traumatic encephalopathy (CTE) is the term coined for the neurodegenerative disease often suspected in athletes with histories of repeated concussion and progressive dementia. Histologically, CTE is defined as a tauopathy with a distribution of tau-positive neurofibrillary tangles (NFTs) that is distinct from other tauopathies, and usually shows an absence of beta-amyloid deposits, in contrast to Alzheimer's disease (AD). Although the connection between repeated concussions and CTE-type neurodegeneration has been recently proposed, this causal relationship has not yet been firmly established. Also, the prevalence of CTE among athletes with multiple concussions is unknown. We performed a consecutive case series brain autopsy study on six retired professional football players from the Canadian Football League (CFL) with histories of multiple concussions and significant neurological decline. All participants had progressive neurocognitive decline prior to death; however, only 3 cases had post-mortem neuropathological findings consistent with CTE. The other 3 participants had pathological diagnoses of AD, amyotrophic lateral sclerosis (ALS), and Parkinson's disease (PD). Moreover, the CTE cases showed co-morbid pathology of cancer, vascular disease, and AD. Our case studies highlight that not all athletes with history of repeated concussions and neurological symptomology present neuropathological changes of CTE. These preliminary findings support the need for further research into the link between concussion and CTE as well as the need to expand the research to other possible causes of taupathy in athletes. They point to a critical need for prospective studies with good sampling methods to allow us to understand the relationship between multiple concussions and the development of CTE.

    Two chronic, traumatic brain injury (TBI) cases are presented, where cognitive function improved following treatment with transcranial light emitting diodes (LEDs). At age 59, P1 had closed-head injury from a motor vehicle accident (MVA) without loss of consciousness and normal MRI, but unable to return to work as development specialist in internet marketing, due to cognitive dysfunction. At 7 years post-MVA, she began transcranial LED treatments with cluster heads (2.1" diameter with 61 diodes each - 9x633nm, 52x870nm; 12-15mW per diode; total power, 500mW; 22.2 mW/cm2) on bilateral frontal, temporal, parietal, occipital and midline sagittal areas (13.3 J/cm2 at scalp, estimated 0.4 J/cm2 to brain cortex per area). Prior to transcranial LED, focused time on computer was 20 minutes. After 2 months of weekly, transcranial LED treatments, increased to 3 hours on computer. Performs nightly home treatments (now, 5 years, age 72); if stops treating >2 weeks, regresses. P2 (age 52F) had history of closed-head injuries related to sports/military training and recent fall. MRI shows fronto-parietal cortical atrophy. Pre-LED, was not able to work for 6 months and scored below average on attention, memory and executive function. Performed nightly transcranial LED treatments at home (9 months) with similar LED device, on frontal and parietal areas. After 4 months of LED treatments, returned to work as executive consultant, international technology consulting firm. Neuropsychological testing (post- 9 months of transcranial LED) showed significant improvement in memory and executive functioning (range, +1 to +2 SD improvement). Case 2 reported reduction in PTSD symptoms.

  10. Filling in the gaps: Anticipatory control of eye movements in chronic mild traumatic brain injury

    Full Text Available A barrier in the diagnosis of mild traumatic brain injury (mTBI stems from the lack of measures that are adequately sensitive in detecting mild head injuries. MRI and CT are typically negative in mTBI patients with persistent symptoms of post-concussive syndrome (PCS, and characteristic difficulties in sustaining attention often go undetected on neuropsychological testing, which can be insensitive to momentary lapses in concentration. Conversely, visual tracking strongly depends on sustained attention over time and is impaired in chronic mTBI patients, especially when tracking an occluded target. This finding suggests deficient internal anticipatory control in mTBI, the neural underpinnings of which are poorly understood. The present study investigated the neuronal bases for deficient anticipatory control during visual tracking in 25 chronic mTBI patients with persistent PCS symptoms and 25 healthy control subjects. The task was performed while undergoing magnetoencephalography (MEG, which allowed us to examine whether neural dysfunction associated with anticipatory control deficits was due to altered alpha, beta, and/or gamma activity. Neuropsychological examinations characterized cognition in both groups. During MEG recordings, subjects tracked a predictably moving target that was either continuously visible or randomly occluded (gap condition. MEG source-imaging analyses tested for group differences in alpha, beta, and gamma frequency bands. The results showed executive functioning, information processing speed, and verbal memory deficits in the mTBI group. Visual tracking was impaired in the mTBI group only in the gap condition. Patients showed greater error than controls before and during target occlusion, and were slower to resynchronize with the target when it reappeared. Impaired tracking concurred with abnormal beta activity, which was suppressed in the parietal cortex, especially the right hemisphere, and enhanced in left caudate and

    In retired professional association football (soccer) players with a past history of repetitive head impacts, chronic traumatic encephalopathy (CTE) is a potential neurodegenerative cause of dementia and motor impairments. From 1980 to 2010, 14 retired footballers with dementia were followed up regularly until death. Their clinical data, playing career, and concussion history were prospectively collected. Next-of-kin provided consent for six to have post-mortem brain examination. Of the 14 male participants, 13 were professional and 1 was a committed amateur. All were skilled headers of the ball and had played football for an average of 26 years. Concussion rate was limited in six cases to one episode each during their careers. All cases developed progressive cognitive impairment with an average age at onset of 63.6 years and disease duration of 10 years. Neuropathological examination revealed septal abnormalities in all six post-mortem cases, supportive of a history of chronic repetitive head impacts. Four cases had pathologically confirmed CTE; concomitant pathologies included Alzheimer's disease (N = 6), TDP-43 (N = 6), cerebral amyloid angiopathy (N = 5), hippocampal sclerosis (N = 2), corticobasal degeneration (N = 1), dementia with Lewy bodies (N = 1), and vascular pathology (N = 1); and all would have contributed synergistically to the clinical manifestations. The pathological diagnosis of CTE was established in four individuals according to the latest consensus diagnostic criteria. This finding is probably related to their past prolonged exposure to repetitive head impacts from head-to-player collisions and heading the ball thousands of time throughout their careers. Alzheimer's disease and TDP-43 pathologies are common concomitant findings in CTE, both of which are increasingly considered as part of the CTE pathological entity in older individuals. Association football is the most popular sport in the world and the potential link between

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease, which is associated with mild repetitive traumatic brain injury (TBI). This long-term and progressive symptom due to TBI was initially called punch-drunk syndrome or dementia pugilistica, since it was believed to be associated with boxing. However, serial neuropathological studies of mild repetitive TBI in the last decade have revealed that CTE occurs not only in boxers but also in a wider population including American football players, wrestlers, and military personnel. CTE has gained large public interest owing to dramatic cases involving retired professional athletes wherein serious behavioral problems and tragic incidents were reported. Unlike mild repetitive TBI, a single episode of severe TBI can cause another type of late-onset neuropsychiatric disease including Alzheimer's disease (AD). Several epidemiological studies have shown that a single episode of severe TBI is one of the major risk factors of AD. Pathologically, both AD and CTE are characterized by abnormal accumulations of hyperphosphorylated tau proteins. However, recent neuropathological studies revealed that CTE demonstrates a unique pattern of tau pathology in neurons and astrocytes, and accumulation of other misfolded proteins such as TDP-43. Currently, no reliable biomarkers of late-onset neurodegenerative diseases following TBI are available, and a definitive diagnosis can be made only via postmortem neuropathological examination. Development in neuroimaging techniques such as tau and amyloid positron emission tomography imaging might not only enable early diagnosis of CTE, but also contribute to the interventions for prevention of late-onset neurodegenerative diseases following TBI. Further studies are necessary to elucidate the mechanisms of neurodegeneration in the living brain of patients with TBI.

    The United States Department of Defense Blast Injury Research Program Coordinating Office organized the 2015 International State-of-the-Science meeting to explore links between blast-related head injury and the development of chronic traumatic encephalopathy (CTE). Before the meeting, the planning committee examined articles published between 2005 and October 2015 and prepared this literature review, which summarized broadly CTE research and addressed questions about the pathophysiological basis of CTE and its relationship to blast- and nonblast-related head injury. It served to inform participants objectively and help focus meeting discussion on identifying knowledge gaps and priority research areas. CTE is described generally as a progressive neurodegenerative disorder affecting persons exposed to head injury. Affected individuals have been participants primarily in contact sports and military personnel, some of whom were exposed to blast. The symptomatology of CTE overlaps with Alzheimer's disease and includes neurological and cognitive deficits, psychiatric and behavioral problems, and dementia. There are no validated diagnostic criteria, and neuropathological evidence of CTE has come exclusively from autopsy examination of subjects with histories of exposure to head injury. The perivascular accumulation of hyperphosphorylated tau (p-tau) at the depths of cortical sulci is thought to be unique to CTE and has been proposed as a diagnostic requirement, although the contribution of p-tau and other reported pathologies to the development of clinical symptoms of CTE are unknown. The literature on CTE is limited and is focused predominantly on head injuries unrelated to blast exposure (e.g., football players and boxers). In addition, comparative analyses of clinical case reports has been challenging because of small case numbers, selection biases, methodological differences, and lack of matched controls, particularly for blast-exposed individuals. Consequently, the

    Players of American football may be at increased risk of long-term neurological conditions, particularly chronic traumatic encephalopathy (CTE). To determine the neuropathological and clinical features of deceased football players with CTE. Case series of 202 football players whose brains were donated for research. Neuropathological evaluations and retrospective telephone clinical assessments (including head trauma history) with informants were performed blinded. Online questionnaires ascertained athletic and military history. Participation in American football at any level of play. Neuropathological diagnoses of neurodegenerative diseases, including CTE, based on defined diagnostic criteria; CTE neuropathological severity (stages I to IV or dichotomized into mild [stages I and II] and severe [stages III and IV]); informant-reported athletic history and, for players who died in 2014 or later, clinical presentation, including behavior, mood, and cognitive symptoms and dementia. Among 202 deceased former football players (median age at death, 66 years [interquartile range, 47-76 years]), CTE was neuropathologically diagnosed in 177 players (87%; median age at death, 67 years [interquartile range, 52-77 years]; mean years of football participation, 15.1 [SD, 5.2]), including 0 of 2 pre-high school, 3 of 14 high school (21%), 48 of 53 college (91%), 9 of 14 semiprofessional (64%), 7 of 8 Canadian Football League (88%), and 110 of 111 National Football League (99%) players. Neuropathological severity of CTE was distributed across the highest level of play, with all 3 former high school players having mild pathology and the majority of former college (27 [56%]), semiprofessional (5 [56%]), and professional (101 [86%]) players having severe pathology. Among 27 participants with mild CTE pathology, 26 (96%) had behavioral or mood symptoms or both, 23 (85%) had cognitive symptoms, and 9 (33%) had signs of dementia. Among 84 participants with severe CTE pathology, 75 (89

    Full Text Available Objectives. Characterize the scale and pattern of long-term atrophy in grey matter (GM, white matter (WM and cerebrospinal (CSF in chronic moderate-severe traumatic brain injury (TBI and its relationship to neurocognitive outcomes.Participants. The TBI group consisted of 17 males with primary diagnosis of moderate-severe closed head injury. Participants had not received any systematic, post-acute rehabilitation and were recruited on average 8.36 years post-injury. The control group consisted of 15 males matched on age and education.Main measures. Neurocognitive battery included widely used tests of verbal memory, visual memory, executive functioning, and attention/organization. GM,WM, and CSF volumes were calculated from segmented T1-weighted anatomical MR images. Voxel-based morphometry was employed to identify brain regions with differences in GM and WM between TBI and control groups.Results. Chronic TBI results in significant neurocognitive impairments, and significant loss of GM and WM volume, and significant increase in CSF volume. Brain atrophy is not widespread, but it is rather distributed in a fronto-thalamic network. The extent of volume loss is predictive of performance on the neurocognitive tests.Conclusion. Significant brain atrophy and associated neurocognitive impairments during the chronic stages of TBI support the notion that TBI results in a chronic condition with lifelong implications.

    Flores, Elaine C; Carnero, Andres M; Bayer, Angela M

    2014-01-01

    This study aimed to evaluate the association between chronic Post-Traumatic Stress Disorder (PTSD) and both structural and cognitive social capital in adult survivors of the 2007 earthquake in Pisco, Peru. Cognitive social capital measures trust, sense of belonging and interpersonal relationships in the community and structural social capital measures group membership, support from community groups and individuals, and involvement in citizenship activities. We conducted a population-based cross-sectional study in five counties in Pisco, selecting 1012 adults through complex, multi-stage random sampling. All participants completed socio-demographic questions and validated Spanish-language versions of the Adapted Social Capital Assessment Tool (SASCAT) and the civilian PTSD checklist (PCL-C). After performing descriptive and bivariate analyses, we carried out prevalence ratio (PR) regression. The overall prevalence of chronic PTSD was 15.9% (95% CI: 12.3, 19.8), much higher than anticipated based on existing evidence. Cognitive social capital was found to be negatively associated with chronic PTSD, while no significant association was found for structural social capital. Specifically, those with high cognitive social capital had an almost two times lower prevalence of chronic PTSD (PR = 1.83, 95% CI: 1.50, 2.22) compared with those with low cognitive social capital. No independent association between structural social capital and chronic PTSD was found (PR = 1.44, 95% CI: 0.70, 2.97). In conclusion, cognitive social capital, but not structural social capital, has a protective influence on the occurrence of chronic PTSD in survivors of natural disasters. These results may have public health implications. For example, pre- and post-disaster community-based interventions that catalyze and foster dimensions of cognitive social capital may aid in ameliorating the effect of earthquakes and other natural disasters on populations with high vulnerability to such events

    Full Text Available Chronic traumatic encephalopathy (CTE is a progressive neurodegenerative disease marked by debilitating cognitive and behavioral symptoms. CTE is thought to be caused by traumatic brain injuries (TBIs, though it remains unclear how the frequency, duration and intensity of TBIs contribute to CTE vulnerability. It is estimated that as many as 4M sports-related TBIs may occur annually in the US, though mild TBIs are often underreported and/or undiagnosed. As participation in athletics is arguably a voluntary and controllable risk factor for TBI, it is important to identify and understand factors that might affect an athlete’s’ likelihood of developing CTE. This review summarizes CTE symptomology and pathology, reviews relevant findings from animal models of TBI/CTE, discusses clinical criteria and emerging technologies used for diagnosis, reviews the extent to which sex differences may contribute to TBI severity and/or recovery and, finally, presents a data-driven protocol for return-to-play procedures for student athletes in contact sports.

    We present a case of chronic traumatic encephalopathy (CTE) in a retired National Football League (NFL) Player with autopsy findings, apolipoprotein E genotype, and brain tissue evidence of chronic brain damage. This 44-year-old retired NFL player manifested a premortem history of cognitive and neuropsychiatric impairment, which included in part, chronic depression, suicide attempts, insomnia, paranoia, and impaired memory before he finally committed suicide. A full autopsy was performed with Polymerase Chain Reaction-based analyses of his blood to determine the apolipoprotein genotype. Histochemical and immunohistochemical analyses were performed on topographical gross sections of the brain. Autopsy confirmed a fatal gunshot wound of the head. The apolipoprotein E genotype was E3/E3 and the brain tissue revealed diffuse cerebral taupathy (Neurofibrillary Tangles and Neuritic Threads). This will be the third case of CTE in a national football player, which has been reported in the medical literature. Omalu et al., reported the first two cases in 2005 and 2006. This case series manifested similar premortem history of neuropsychiatric impairment with autopsy evidence of cerebral taupathy without any neuritic amyloidopathy. For a definitive diagnosis of CTE to be made, and for medicolegal purposes, a full autopsy must be performed with histochemical and immunohistochemical analyses of the brain to identify the presence of Neurofibrillary Tangles (NFTs) and Neuritic Threads (NTs). Further longitudinal prospective studies are required to confirm the common denominators and epidemiology of CTE in professional American football players, which have been identified by this case series.

    Post-traumatic stress disorder (PTSD) is psychiatric disease, which can occur following exposure to traumatic events. PTSD may be acute or chronic, and can have a waxing and waning course of symptoms. It has been hypothesized that proinflammatory cytokines and chemokines in the cerebrospinal fluid (CSF) or plasma might be mediators of the psychophysiological mechanisms relating a history of trauma exposure to changes in behavior and mental health disorders, and medical morbidity. Here we test the cytokine/chemokine hypothesis for PTSD by examining levels of 17 classical cytokines and chemokines in CSF, sampled at 0900 hours, and in plasma sampled hourly for 24 h. The PTSD and healthy control patients are from the NIMH Chronic PTSD and healthy control cohort, initially described by Bonne et al. (2011), in which the PTSD patients have relatively low comorbidity for major depressive disorder (MDD), drug or alcohol use. We find that in plasma, but not CSF, the bivariate MCP4 (CCL13)/ MCP1(CCL2) ratio is ca. twofold elevated in PTSD patients compared with healthy controls. The MCP-4/MCP-1 ratio is invariant over circadian time, and is independent of gender, body mass index or the age at which the trauma was suffered. By contrast, MIP-1β is a candidate biomarker for PTSD only in females, whereas TARC is a candidate biomarker for PTSD only in males. It remains to be discovered whether these disease-specific differences in circadian expression for these specific immune signaling molecules are biomarkers, surrogates, or drivers for PTSD, or whether any of these analytes could contribute to therapy.

    Currently, only presumptive diagnosis of chronic traumatic encephalopathy (CTE) can be made in living patients. We present a modality that may be instrumental to the definitive diagnosis of CTE in living patients based on brain autopsy confirmation of [F-18]FDDNP-PET findings in an American football player with CTE. [F-18]FDDNP-PET imaging was performed 52 mo before the subject's death. Relative distribution volume parametric images and binding values were determined for cortical and subcortical regions of interest. Upon death, the brain was examined to identify the topographic distribution of neurodegenerative changes. Correlation between neuropathology and [F-18]FDDNP-PET binding patterns was performed using Spearman rank-order correlation. Mood, behavioral, motor, and cognitive changes were consistent with chronic traumatic myeloencephalopathy with a 22-yr lifetime risk exposure to American football. There were tau, amyloid, and TDP-43 neuropathological substrates in the brain with a differential topographically selective distribution. [F-18]FDDNP-PET binding levels correlated with brain tau deposition (rs = 0.59, P = .02), with highest relative distribution volumes in the parasagittal and paraventricular regions of the brain and the brain stem. No correlation with amyloid or TDP-43 deposition was observed. [F-18]FDDNP-PET signals may be consistent with neuropathological patterns of tau deposition in CTE, involving areas that receive the maximal shearing, angular-rotational acceleration-deceleration forces in American football players, consistent with distinctive and differential topographic vulnerability and selectivity of CTE beyond brain cortices, also involving midbrain and limbic areas. Future studies are warranted to determine whether differential and selective [F-18]FDDNP-PET may be useful in establishing a diagnosis of CTE in at-risk patients.

    Sleep disturbance is common in chronic post-traumatic stress disorder (PTSD). However, prior work has demonstrated that there are inconsistencies between subjective and objective assessments of sleep disturbance in PTSD. Therefore, we investigated whether subjective or objective sleep assessment has greater clinical utility to differentiate PTSD patients from healthy subjects. Further, we evaluated whether the combination of subjective and objective methods improves the accuracy of classification into patient versus healthy groups, which has important diagnostic implications. We recruited 32 chronic war-induced PTSD patients and 32 age- and gender-matched healthy subjects to participate in this study. Subjective (i.e. from three self-reported sleep questionnaires) and objective sleep-related data (i.e. from actigraphy scores) were collected from each participant. Subjective, objective, and combined (subjective and objective) sleep data were then analyzed using support vector machine classification. The classification accuracy, sensitivity, and specificity for subjective variables were 89.2%, 89.3%, and 89%, respectively. The classification accuracy, sensitivity, and specificity for objective variables were 65%, 62.3%, and 67.8%, respectively. The classification accuracy, sensitivity, and specificity for the aggregate variables (combination of subjective and objective variables) were 91.6%, 93.0%, and 90.3%, respectively. Our findings indicate that classification accuracy using subjective measurements is superior to objective measurements and the combination of both assessments appears to improve the classification accuracy for differentiating PTSD patients from healthy individuals.

    Full Text Available Vertigo, was provoked and right torsional up-beat nystagmus was observed in a 47-year-old patient when she was placed into the right Hallpike-Dix test position using infrared goggle technology. The clinical diagnosis was benign paroxysmal positional vertigo (BPPV, specifically right posterior canalithiasis, resulting from a mild traumatic brain injury (TBI suffered approximately six-months earlier. Previous medical consultations did not include vestibular system examination, and Meclizine was prescribed to suppress her chief complaint of vertigo. Ultimately, the patient was successfully managed by performing two canalith repositioning maneuvers during a single clinical session. The patient reported 100% resolution of symptoms upon reexamination the following day, and the Hallpike-Dix test was negative. Continued symptom resolution was subjectively reported 10 days postintervention via telephone consultation. This case report supports previous publications concerning the presence of BPPV following TBI and the need for inclusion of vestibular system examination during medical consultation.

    Full Text Available Abstract Background Individuals who sustain traumatic brain injuries (TBIs often continue to experience significant impairment of cognitive functions mediated by the prefrontal cortex well into chronic stages of recovery. Traditional brain training programs that focus on improving specific skills fall short of addressing integrative functions that draw upon multiple higher-order processes critical for social and vocational integration. In the current study, we compare the effects of two short-term, intensive, group-based cognitive rehabilitation programs for individuals with chronic TBI. One program emphasizes learning about brain functions and influences on cognition, while the other program adopts a top-down approach to improve abstract reasoning abilities that are largely reliant on the prefrontal cortex. These treatment programs are evaluated in civilian and military veteran TBI populations. Methods/design One hundred individuals are being enrolled in this double-blinded clinical trial (all measures and data analyses will be conducted by blinded raters and analysts. Each individual is randomly assigned to one of two treatment conditions, with each condition run in groups of five to seven individuals. The primary anticipated outcomes are improvement in abstract reasoning and everyday life functioning, measured through behavioral tasks and questionnaires, and attention modulation, as measured by functional neuroimaging. Secondary expected outcomes include improvements in the cognitive processes of working memory, attention, and inhibitory control. Discussion Results of this trial will determine whether cognitive rehabilitation aimed at teaching TBI-relevant information about the brain and cognition versus training in TBI-affected thinking abilities (e.g., memory, attention, and executive functioning can improve outcomes in chronic military and civilian TBI patient populations. It should shed light on the nature of improvements and the

    The primary aim of this study was to assess the level of engagement in computer-based simulations of functional tasks, using a haptic device for people with chronic traumatic brain injury. The objectives were to design functional tasks using force feedback device and determine if it could measure motor performance improvement. A prospective crosssectional study was performed in a biomedical research facility. The testing environment consisted of a single, interactive, stylus-driven computer session navigating virtual scenes in 3D space. Subjects had a haptic training session (TRAIN) and then had three chances to perform each virtual task: (i) remove tools from a workbench (TOOL), (ii) compose 3 letter words (SPELL), (iii) manipulate utensils to prepare a sandwich (SAND), and (iv) tool use (TUSE). Main Outcome Measures included self-report of engagement in the activities, improved performance on simulated tasks and observer estimate as measured by time to completion or number of words completed from baseline, correlations among performance measures and self-reports of boredom, neuropsychological symptom inventory (NSI), and The Purdue Peg Motor Test (PPT). Participants were 19 adults from the community with a 1 year history of non-penetrating traumatic brain injury (TBI) and were able to use computers. Seven had mild, 3 moderate and 9 severe TBIs. Mean score on the Boredom Proneness Scale (BPS): 107 (normal range 81-117); mean NSI:32; mean PPT 54 (normal range for assembly line workers >67). Responses to intervention: 3 (15%)subjects did not repeat all three trials of the tasks; 100% reported they were highly engaged in the interactions; 6 (30%) reported they had a high level of frustration with the tasks, but completed them with short breaks. Performance measures: Comparison of baseline to post training: TOOL time decreased by (mean) 60 sec; SPELL increased by 2.7 words; TUSE time decreased by (mean) 68 sec; and SAND time decreased by (mean) 72 sec.

  13. Chronic Hypopituitarism Associated with Increased Postconcussive Symptoms Is Prevalent after Blast-Induced Mild Traumatic Brain Injury

    Full Text Available The most frequent injury sustained by US service members deployed to Iraq or Afghanistan is mild traumatic brain injuries (mTBI, or concussion, by far most often caused by blast waves from improvised explosive devices or other explosive ordnance. TBI from all causes gives rise to chronic neuroendocrine disorders with an estimated prevalence of 25–50%. The current study expands upon our earlier finding that chronic pituitary gland dysfunction occurs with a similarly high frequency after blast-related concussions. We measured circulating hormone levels and accessed demographic and testing data from two groups of male veterans with hazardous duty experience in Iraq or Afghanistan. Veterans in the mTBI group had experienced one or more blast-related concussion. Members of the deployment control (DC group encountered similar deployment conditions but had no history of blast-related mTBI. 12 of 39 (31% of the mTBI participants and 3 of 20 (15% veterans in the DC group screened positive for one or more neuroendocrine disorders. Positive screens for growth hormone deficiency occurred most often. Analysis of responses on self-report questionnaires revealed main effects of both mTBI and hypopituitarism on postconcussive and posttraumatic stress disorder (PTSD symptoms. Symptoms associated with pituitary dysfunction overlap considerably with those of PTSD. They include cognitive deficiencies, mood and anxiety disorders, sleep problems, diminished quality of life, deleterious changes in metabolism and body composition, and increased cardiovascular mortality. When such symptoms are due to hypopituitarism, they may be alleviated by hormone replacement. These findings suggest consideration of routine post-deployment neuroendocrine screening of service members and veterans who have experienced blast-related mTBI and are reporting postconcussive symptoms.

  14. High prevalence of chronic pituitary and target-organ hormone abnormalities after blast-related mild traumatic brain injury

    Full Text Available Studies of traumatic brain injury from all causes have found evidence of chronic hypopituitarism, defined by deficient production of one or more pituitary hormones at least one year after injury, in 25-50% of cases. Most studies found the occurrence of posttraumatic hypopituitarism (PTHP to be unrelated to injury severity. Growth hormone deficiency (GHD and hypogonadism were reported most frequently. Hypopituitarism, and in particular adult GHD, is associated with symptoms that resemble those of PTSD, including fatigue, anxiety, depression, irritability, insomnia, sexual dysfunction, cognitive deficiencies, and decreased quality of life. However, the prevalence of PTHP after blast-related mild TBI (mTBI, an extremely common injury in modern military operations, has not been characterized. We measured concentrations of 12 pituitary and target-organ hormones in two groups of male US Veterans of combat in Iraq or Afghanistan. One group consisted of participants with blast-related mTBI whose last blast exposure was at least one year prior to the study. The other consisted of Veterans with similar military deployment histories but without blast exposure. Eleven of 26, or 42% of participants with blast concussions were found to have abnormal hormone levels in one or more pituitary axes, a prevalence similar to that found in other forms of TBI. Five members of the mTBI group were found with markedly low age-adjusted insulin-like growth factor-I (IGF-I levels indicative of probable GHD, and three had testosterone and gonadotropin concentrations consistent with hypogonadism. If symptoms characteristic of both PTHP and PTSD can be linked to pituitary dysfunction, they may be amenable to treatment with hormone replacement. Routine screening for chronic hypopituitarism after blast concussion shows promise for appropriately directing diagnostic and therapeutic decisions that otherwise may remain unconsidered and for markedly facilitating recovery and

    Soldiers with a traumatic brain injury (TBI) present with an array of neuropsychiatric symptoms that can be grouped into nosological clusters: (1) cognitive dysfunctions: difficulties in memory, attention, language, visuospatial cognition, sensory-motor integration, affect recognition, and/or executive function typically associated with neocortical damage; (2) neurobehavioral disorders: mood, affect, anxiety, posttraumatic stress, and psychosis, as well as agitation, sleep problems, and libido loss, that may have been caused by damage to the cortex, limbic system, and/or brain stem monoaminergic projection systems; (3) somatosensory disruptions: impaired smell, vision, hearing, equilibrium, taste, and somatosensory perception frequently caused by trauma to the sensory organs or their projections through the brain stem to central processing systems; (4) somatic symptoms: headache and chronic pain; and (5) substance dependence. TBI-related cognitive impairment is common in veterans who have served in recent conflicts in the Middle East and is often related to blasts from improvised explosive devices. Although neurobehavioral disorders such as depression and posttraumatic stress disorder commonly occur after combat, the presentation of such disorders in those with head injury may pass undetected with use of current diagnostic criteria and neuropsychological instruments. With a multidimensional approach (such as the biopsychosocial model) applied to each symptom cluster, psychological, occupational, and social dysfunction can be delineated and managed.

    The purpose of this study was to evaluate alterations of regional cerbral blood flow (CBF) and cerebrovascular reserve (CVR), and correlation between these alternations and cognitive dysfunctin in patients with chronic traumatic brain injury (TBI) and normal brain MRI findings. Thirty TBI patients and 19 healthy volunteers underwent rest/acetazolaminde brain SPECT using Tc-99m HMPAO. Korean-Wechsler Adult Intelligence scale test was also performed in the patient group. Statistical analysis was performed with statistical parametric mapping software (SPM '97). CBF was diminished in the left hemisphere including Wernicke's area in all patients with lower verbal scale scores. In addition, a reduction in CBF in the right frontal, temporal and parietal cortices was related with depressed scores in information, digital span, arithmetic and similarities. In patients with lower performance scale scores, CBF was mainly diminished in the right hemisphere including superior temporal and supramarginal gyri, premotor, primary somatomotor and a part of prefrontal cortices, left frontal lobe and supramarginal gyrus. CVR was diminished in sixty-four Brodmann's areas compared to control. A reduction in CVR was demonstrated bilaterally in the frontal and temporal lobes in patients with lower scores in both verbal and performance tests, and in addition, both inferior parietal and occipital lobes in information subset. Alterations of CBF and CVR were demonstrated in the symptomatic TBI patients with normal MRI finding. These alterations were correlated with the change of intelligence, of which the complex functions are subserved by multiple interconnected cortical structures.=20

    CCL11, a protein previously associated with age-associated cognitive decline, is observed to be increased in the brain and cerebrospinal fluid (CSF) in chronic traumatic encephalopathy (CTE) compared to Alzheimer’s disease (AD). Using a cohort of 23 deceased American football players with neuropathologically verified CTE, 50 subjects with neuropathologically diagnosed AD, and 18 non-athlete controls, CCL11 was measured with ELISA in the dorsolateral frontal cortex (DLFC) and CSF. CCL11 levels were significantly increased in the DLFC in subjects with CTE (fold change = 1.234, p football (β = 0.426, p = 0.048) independent of age (β = -0.046, p = 0.824). Preliminary analyses of a subset of subjects with available post-mortem CSF showed a trend for increased CCL11 among individuals with CTE (p = 0.069) mirroring the increase in the DLFC. Furthermore, an association between CSF CCL11 levels and the number of years exposed to football (β = 0.685, p = 0.040) was observed independent of age (β = -0.103, p = 0.716). Finally, a receiver operating characteristic (ROC) curve analysis demonstrated CSF CCL11 accurately distinguished CTE subjects from non-athlete controls and AD subjects (AUC = 0.839, 95% CI 0.62–1.058, p = 0.028). Overall, the current findings provide preliminary evidence that CCL11 may be a novel target for future CTE biomarker studies. PMID:28950005

    Subluxation of the extensor tendon results from a disruption to the sagittal band at the metacarpophalangeal joint. When conservative treatment fails to correct the subluxation, surgical treatment may be necessary. Surgical techniques for chronic cases vary in graft source and graft pathway. We present a surgical technique to recentralize and stabilize the extensor tendon using a residual ruptured sagittal band. This technique is simple and effective without donor site morbidity and seems to provide potential biomechanical advantages by restoring nearly normal anatomy.

    2018-01-01

    Full Text Available Objective: Central pain can occur following traumatic brain injury, leading to poor functional recovery, limitation of activities of daily living, and decreased quality of life. The aim of this study was to determine whether high-frequency (10 Hz repetitive transcranial magnetic stimulation, applied over the primary motor cortex of the affected hemisphere, can be used to manage chronic central pain after mild traumatic brain injury. Design: Prospective randomized feasibility study. Methods: Twelve patients with mild traumatic brain injury and chronic central pain were randomly assigned to transcranial magnetic stimulation (high-frequency stimulation, 10 sessions or sham groups. Diffuse tensor tractography revealed partially injured spinothalamocortical tracts in all recruited patients. A numerical rating scale (NRS was used to evaluate pain intensity during pre-treatment and immediately after the 5th transcranial magnetic stimulation session (post1, 10th transcranial magnetic stimulation session (post2, and 1 (post3, 2 (post4, and 4 weeks (post 5 after finishing treatment. Physical and mental health status were evaluated using the Short Form 36 Health Survey (SF-36, including physical and mental component scores (PCS, MCS. Results: The NRS score of the repetitive transcranial magnetic stimulation group was significantly lower than the sham group score at all clinical evaluation time-points during and after transcranial magnetic stimulation sessions. The transcranial magnetic stimulation group’s SF-36 PCS score was significantly higher at post2, post3, post4, and post5 compared with the sham group. Conclusion: High-frequency transcranial magnetic stimulation may be used to manage chronic central pain and improve quality of life in patients with mild traumatic brain injury. However, this is a pilot study and further research is needed.

  1. Exploring the physiological correlates of chronic mild traumatic brain injury symptoms

    Full Text Available We report on the results of a multimodal imaging study involving behavioral assessments, evoked and resting-state BOLD fMRI, and DTI in chronic mTBI subjects. We found that larger task-evoked BOLD activity in the MT+/LO region in extra-striate visual cortex correlated with mTBI and PTSD symptoms, especially light sensitivity. Moreover, higher FA values near the left optic radiation (OR were associated with both light sensitivity and higher BOLD activity in the MT+/LO region. The MT+/LO region was localized as a region of abnormal functional connectivity with central white matter regions previously found to have abnormal physiological signals during visual eye movement tracking (Astafiev et al., 2015. We conclude that mTBI symptoms and light sensitivity may be related to excessive responsiveness of visual cortex to sensory stimuli. This abnormal sensitivity may be related to chronic remodeling of white matter visual pathways acutely injured.

    Full Text Available Mild to moderate traumatic brain injury (TBI due to blast exposure is frequently diagnosed in veterans returning from the wars in Iraq and Afghanistan. However, it is unclear whether neural damage resulting from blast TBI differs from that found in TBI due to blunt-force trauma (e.g., falls and motor vehicle crashes. Little is also known about the effects of blast TBI on neural networks, particularly over the long term. Because impairment in working memory has been linked to blunt-force TBI, the present functional magnetic resonance imaging (fMRI study sought to investigate whether brain activation in response to a working memory task would discriminate blunt-force from blast TBI. Twenty-five veterans (mean age = 29.8 years, standard deviation = 6.01 years, 1 female who incurred TBI due to blast an average of 4.2 years prior to enrollment and 25 civilians (mean age = 27.4 years, standard deviation = 6.68 years, 4 females with TBI due to blunt-force trauma performed the Sternberg Item Recognition Task while undergoing fMRI. The task involved encoding 1, 3, or 5 items in working memory. A group of 25 veterans (mean age = 29.9 years, standard deviation = 5.53 years, 0 females and a group of 25 civilians (mean age = 27.3 years, standard deviation = 5.81 years, 0 females without history of TBI underwent identical imaging procedures and served as controls. Results indicated that the civilian TBI group and both control groups demonstrated a monotonic relationship between working memory set size and activation in the right caudate during encoding, whereas the blast TBI group did not (p < 0.05, corrected for multiple comparisons using False Discovery Rate. Blast TBI was also associated with worse performance on the Sternberg Item Recognition Task relative to the other groups, although no other group differences were found on neuropsychological measures of episodic memory, inhibition, and general processing speed.

    Post-traumatic stress disorder (PTSD) is in part due to a deficit in memory consolidation and extinction. Oxytocin (OXT) has anxiolytic effects and promotes prosocial behaviors in both rodents and humans, and evidence suggests that it plays a role in memory consolidation. We studied the effects of administered OXT and social co-housing in a rodent model of PTSD. Acute OXT yielded a short-term increase in the recall of the traumatic memory if administered immediately after trauma. Low doses of OXT delivered chronically had a cumulating anxiolytic effect that became apparent after 4 days and persisted. Repeated injections of OXT after short re-exposures to the trauma apparatus yielded a long-term reduction in anxiety. Co-housing with naive nonshocked animals decreased the memory of the traumatic context compared with single-housed animals. In the long term, these animals showed less thigmotaxis and increased interest in novel objects, and a low OXT plasma level. Co-housed PTSD animals showed an increase in risk-taking behavior. These results suggest beneficial effects of OXT if administered chronically through increases in memory consolidation after re-exposure to a safe trauma context. We also show differences between the benefits of social co-housing with naive rats and co-housing with other shocked animals on trauma-induced long-term anxiety.

    To date, a clear differentiation of disability, cognitive deficits, and central sensitization between chronic neck pain of a traumatic nature and that of a nontraumatic nature is lacking. This study aimed to examine differences in disability, cognitive deficits, and central sensitization between women with traumatic and idiopathic (nontraumatic) chronic neck pain and women who were healthy. In addition, interrelationships among these variables were investigated. This was a case-control study. Ninety-five women (28 women who were healthy [controls], 35 women with chronic idiopathic neck pain [CINP], and 32 women with chronic whiplash-associated disorders [CWAD] [traumatic]) were enrolled in the study. First, all participants completed standardized questionnaires to investigate pain-related disability and health-related quality of life. Next, cognitive performance was assessed. Finally, pressure pain thresholds and conditioned pain modulation were examined to investigate central sensitization. Pain-related disability, reduced health-related quality of life, and cognitive deficits were present in participants with CWAD and, to a significantly lesser extent, in participants with CINP. Local hyperalgesia was demonstrated in participants with CWAD and CINP but not in women who were healthy. However, distant hyperalgesia and decreased conditioned pain modulation efficacy were shown only in participants with CWAD; this result is indicative of the presence of central sensitization. Moderate to strong Spearman correlations (ρ=.456-.701) among disability, cognitive deficits, and hyperalgesia (local and distant) were observed in participants with CWAD. In participants with CINP, only local hyperalgesia and subjective cognitive deficits were moderately (ρ=.463) correlated. No conclusions about the causality of the observed correlations can be drawn. This innovative research revealed important differences between women with CWAD and women with CINP and thus provided evidence

    Objective The current study examined multiple stress indicators (chronic, perceived, traumatic) in relation to prevalent coronary heart disease (CHD), stroke, and major cardiovascular disease (CVD) risk factors (i.e., diabetes, dyslipidemia, hypertension, current smoking) in the multi-site Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (2010–2011). Methods Participants were 5313 men and women, 18–74 years old, representing diverse Hispanic/Latino ethnic backgrounds, who underwent a comprehensive baseline clinical exam and sociocultural exam with measures of stress. Results Chronic stress burden was related to a higher prevalence of CHD after adjusting for sociodemographic, behavioral and biological risk factors [OR (95% CI) = 1.22, (1.10–1.36)] and related to stroke prevalence in the model adjusted for demographic and behavioral factors [OR (95% CI) = 1.26, (1.03–1.55∂)]. Chronic stress was also related to a higher prevalence of diabetes [OR=1.20, (1.11–1.31)] and hypertension [OR=1.10 (1.02–1.19)] in individuals free from CVD (N=4926). Perceived stress [OR=1.03 (1.01–1.05)] and traumatic stress [OR=1.15 (1.05–1.26)] were associated with a higher prevalence of smoking. Participants who reported a greater number of lifetime traumatic events also unexpectedly showed a lower prevalence of diabetes [OR=.89 (.83–.97)] and hypertension [OR=.88 (.82–.93)]. Effects were largely consistent across age and sex groups. Conclusions The study underscores the utility of examining multiple indicators of stress in relation to health, since the direction and consistency of associations may vary across distinct stress conceptualizations. In addition, the study suggests that chronic stress is related to higher CVD risk and prevalence in Hispanics/Latinos, the largest U.S. ethnic minority group. PMID:24979579

    To test efficacy of 8-session, 1:1 treatment, anger self-management training (ASMT), for chronic moderate to severe traumatic brain injury (TBI). Three US outpatient treatment facilities. Ninety people with TBI and elevated self-reported anger; 76 significant others (SOs) provided collateral data. Multicenter randomized controlled trial with 2:1 randomization to ASMT or structurally equivalent comparison treatment, personal readjustment and education (PRE). Primary outcome assessment 1 week posttreatment; 8-week follow-up. Response to treatment defined as 1 or more standard deviation change in self-reported anger. SO-rated anger, emotional and behavioral status, satisfaction with life, timing of treatment response, participant and SO-rated global change, and treatment satisfaction. State-Trait Anger Expression Inventory-Revised Trait Anger (TA) and Anger Expression-Out (AX-O) subscales; Brief Anger-Aggression Questionnaire (BAAQ); Likert-type ratings of treatment satisfaction, global changes in anger and well-being. After treatment, ASMT response rate (68%) exceeded that of PRE (47%) on TA but not AX-O or BAAQ; this finding persisted at 8-week follow-up. No significant between-group differences in SO-reported response rates, emotional/behavioral status, or life satisfaction. ASMT participants were more satisfied with treatment and rated global change in anger as significantly better; SO ratings of global change in both anger and well-being were superior for ASMT. ASMT was efficacious and persistent for some aspects of problematic anger. More research is needed to determine optimal dose and essential ingredients of behavioral treatment for anger after TBI.

    Full Text Available Traumatic brain injury (TBI is a mechanical insult to the brain caused by external forces and associated with inflammation and oxidative stress. The patients may show different profiles of neurological recovery and a combination of oxidative damage and inflammatory processes can affect their courses. It is known that an over-expression of cytokines can be seen in peripheral blood in the early hours/days after the injury, but little is known about the weeks and months encompassing the post-acute and chronic phases. In addition, no information is available about the antioxidant responses mediated by the major enzymes that regulate ROS levels: superoxide dismutase (SOD, catalase (CAT, peroxidases, and GSH related enzymes. This study investigates the 6-month trends of inflammatory markers and antioxidant responses in 22 severe TBI patients with prolonged disorders of consciousness, consecutively recruited in a dedicated neuro-rehabilitation facility. Patients with a high degree of neurological impairment often show an uncertain outcome. In addition, the profiles of plasma activities were related to the neurological recovery after 12 months.Venous peripheral blood samples were taken blindly as soon as clinical signs and laboratory markers confirmed the absence of infections, 3 and 6 months later. The clinical and neuropsychological assessment continued up to 12 months. Nineteen patients completed the follow up. In the chronic phase, persistent high plasma levels of cytokines can interfere with cognitive functioning and higher post-acute levels of cytokines (IFN-g, TNF-a, IL1b, IL6 are associated with poorer cognitive recoveries 12 months later. Moreover, higher IFN- γ, higher TNF-α and lower glutathione peroxidase (GPx activity are associated with greater disability.The results add evidence of persistent inflammatory response, provide information about long-term imbalance of antioxidant activity and suggest that the over-production of cytokines and

    One week following unilateral lung contusion (LC), rat lungs demonstrate full histologic recovery. When animals undergo LC plus the addition of chronic restraint stress (CS), wound healing is significantly delayed. Mesenchymal stem cells (MSCs) are pluripotent cells capable of immunomodulation, which have been the focus of much research in wound healing and tissue regeneration. We hypothesize that the addition of MSCs will improve wound healing in the setting of CS. Male Sprague-Dawley rats (n = 6-7 per group) were subjected to LC/CS with or without the injection of MSCs. MSCs were given as a single intravenous dose of 5 × 10 cells in 1 mL Iscove's Modified Dulbecco's Medium at the time of LC. Rats were subjected to 2 hours of restraint stress on Days 1 to 6 following LC. Seven days following injury, rats were sacrificed, and the lungs were examined for histologic evidence of wound healing using a well-established histologic lung injury score (LIS) to grade injury. LIS examines inflammatory cells/high-power field (HPF) averaged over 30 fields, interstitial edema, pulmonary edema, and alveolar integrity, with scores ranging from 0 (normal) to 11 (highly damaged). Peripheral blood was analyzed by flow cytometry for the presence of T-regulatory (C4CD25FoxP3) cells. Data were analyzed by analysis of variance followed by Tukey's multiple comparison test, expressed as mean (SD). As previously shown, 7 days following isolated LC, LIS has returned to 0.83 (0.41), with a subscore of zero for inflammatory cells/HPF. The addition of CS results in an LIS of 4.4 (2.2), with a subscore of 1.9 (0.7) for inflammatory cells/HPF. Addition of MSC to LC/CS decreased LIS to 1.7 (0.8), with a subscore of zero for inflammatory cells/HPF. Furthermore, treatment of animals undergoing LC/CS with MSCs increased the %T-regulatory cells by 70% in animals undergoing LC/CS alone (12.9% [2.4]% vs. 6.2% [1.3%]). Stress-induced impairment of wound healing is reversed by the addition of MSCs given

    A 3-year old male who sustained 2(nd) and 3(rd) degree burns that covered approximately 60% TBSA presented to a large adult and pediatric verified burn center. On hospital day (HD) 26 of his stay, Candida fungemia was identified by blood culture, delaying operative management until HD 47. On HD 47, after his first operative intervention, the patient developed a persistent metabolic and lactic acidosis. On HD 66, a search for a cause of his osmol gap of 56 mOsm/kg revealed a potential source-propylene glycol. Previous studies have implicated the propylene glycol emulsifier in the silver sulfadiazine that was being applied to his skin as a rare cause of lactic acidosis in severely burned patients. Within 24 hours of stopping the silver sulfadiazine therapy, his lactic acidosis and osmol gap resolved; within 72 hours his metabolic acidosis resolved. Silver sulfadiazine is commonly used adjunct therapy in the treatment of 2(nd) and 3(rd) degree burns and generally has few adverse reactions. The absorption of propylene glycol systemically can rarely occur when applied to extensive burns, presumably due to the disruption of the skin barrier; the half-life of PG is 10 hours and can be prolonged with renal disease because ~50% of the sulfadiazine is excreted in the urine unchanged. When propylene glycol is present systemically, it is metabolized to lactic acid in the liver, which can cause a lactic acidosis. Several commonly used drugs also use propylene glycol as an emulsifier, including IV preparations of lorazepam, pentobarbital, phenobarbital, and phenytoin. In all of these clinical scenarios, including severe burn patients that are being treated with silver sulfadiazine, both lactic acid and propylene glycol levels should be measured to monitor for this rare, potentially serious co-morbidity.

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    The long-term pathological effects of chronic epilepsy on normal brain ageing are unknown. Previous clinical and epidemiological studies show progressive cognitive decline in subsets of patients and an increased prevalence of Alzheimer's disease in epilepsy. In a post-mortem series of 138 patients with long-term, mainly drug-resistant epilepsy, we carried out Braak staging for Alzheimer's disease neurofibrillary pathology using tau protein immunohistochemistry. The stages were compared with clinicopathological factors, including seizure history and presence of old traumatic brain injury. Overall, 31% of cases were Braak Stage 0, 36% Stage I/II, 31% Stage III/IV and 2% Stage V/VI. The mean age at death was 56.5 years and correlated with Braak stage (P < 0.001). Analysis of Braak stages within age groups showed a significant increase in mid-Braak stages (III/IV), in middle age (40-65 years) compared with data from an ageing non-epilepsy series (P < 0.01). There was no clear relationship between seizure type (generalized or complex partial), seizure frequency, age of onset and duration of epilepsy with Braak stage although higher Braak stages were noted with focal more than with generalized epilepsy syndromes (P < 0.01). In 30% of patients, there was pathological evidence of traumatic brain injury that was significantly associated with higher Braak stages (P < 0.001). Cerebrovascular disease present in 40.3% and cortical malformations in 11.3% were not significantly associated with Braak stage. Astrocytic-tau protein correlated with the presence of both traumatic brain injury (P < 0.01) and high Braak stage (P < 0.001). Hippocampal sclerosis, identified in 40% (bilateral in 48%), was not associated with higher Braak stages, but asymmetrical patterns of tau protein accumulation within the sclerotic hippocampus were noted. In over half of patients with cognitive decline, the Braak stage was low indicating causes other than Alzheimer's disease pathology. In summary

    We studied whether brain perfusion SPECT is useful in the psychiatric disability evaluation of patients with chronic traumatic brain injury (TBI). Sixty-nine patients (M:F=58:11, age 39 ± 14 years) who underwent Tc-99m HMPAO brain SPECT, brain MRI and neuropsychological (NP) tests during hospitalization in psychiatric wards for the psychiatric disability evaluation were included; the severity of injury was mild in 31, moderate in 17 and severe in 21. SPECT, MRI, NP tests were performed 6 ∼ 61 months (mean 23 months) post-injury. Diagnostic accuracy of SPECT and MRI to show hypoperfusion or abnormal signal intensity in patients with cognitive impairment represented by NP test results were compared. Forty-two patients were considered to have cognitive impairment on NP tests and 27 not. Brain SPECT showed 71% sensitivity and 85% specificity, while brain MRI showed 62% sensitivity and 93% specificity (p>0.05, McNemar test). SPECT found more cortical lesions and MRI was superior in detecting white matter lesions. sensitivity and specificity of 31 mild TBI patients were 45%, 90% for SPECT and 27%, 100% for MRI (p>0.05, McNemar test). Among 41 patients with normal brain MRI, SEPCT showed 63% sensitivity (50% for mild TBI) and 88% specificity (85% for malingerers). Brain SPECT has a supplementary role to neuropsychological tests in the psychiatric disability evaluation of chronic TBI patients by detecting more cortical lesions than MRI

    Prior studies have demonstrated training-induced changes in the healthy adult brain. Yet, it remains unclear how the injured brain responds to cognitive training months-to-years after injury. Sixty individuals with chronic traumatic brain injury (TBI) were randomized into either strategy-based ( N  = 31) or knowledge-based ( N  = 29) training for 8 weeks. We measured cortical thickness and resting-state functional connectivity (rsFC) before training, immediately posttraining, and 3 months posttraining. Relative to the knowledge-based training group, the cortical thickness of the strategy-based training group showed diverse temporal patterns of changes over multiple brain regions ( p vertex  training group induced only monotonic increases in connectivity, relative to the knowledge-based training group (| Z | > 1.96, p NBS  training group yielded monotonic improvement in scores for the trail-making test ( p  training-induced changes in cortical thickness ( p vertex  training group. These findings suggest that training-induced brain plasticity continues through chronic phases of TBI and that brain connectivity and cortical thickness may serve as markers of plasticity.

    This study was undertaken to determine whether changes had occurred in the numbers of burns that could be related to backyard burning subsequent to the introduction of the council tax throughout Eire for the collection of household refuse. Numbers of patients admitted to our unit who had sustained burns by burning rubbish were recorded prospectively over a period of 12 months. A random control group was taken as three years prior to this and results found by retrospective chart review. Between January and November 2005, 168 patients were admitted to the National Burns Unit, St James's Hospital Dublin, Ireland. Nineteen of these patients sustained flame burns from backyard burning. One hundred and seventy patients were admitted in the comparative period of 2002; Seven of these from backyard burning. The total number of inpatient days for these patients in 2005 (255) was significantly more than in 2002 (68) (p=0.024). The numbers in our study show a marked increase in the number of patients sustaining burns in this manner, and appear to correlate with the introduction of bin charges by a number of county councils around the country last year. This study demonstrates that the introduction of legislation can have an unforeseen adverse affect on the population if not introduced in correlation with appropriate public education. While the introduction of waste charges represents a very necessary move forward in waste disposal in Ireland, public awareness campaigns should be implemented to prevent further such injuries from occurring.

    Full Text Available Management of burn injury has always been the domain of burn specialists. Since ancient time, local and systemic remedies have been advised for burn wound dressing and burn scar prevention. Management of burn wound inflicted by the different physical and chemical agents require different regimes which are poles apart from the regimes used for any of the other traumatic wounds. In extensive burn, because of increased capillary permeability, there is extensive loss of plasma leading to shock while whole blood loss is the cause of shock in other acute wounds. Even though the burn wounds are sterile in the beginning in comparison to most of other wounds, yet, the death in extensive burns is mainly because of wound infection and septicemia, because of the immunocompromised status of the burn patients. Eschar and blister are specific for burn wounds requiring a specific treatment protocol. Antimicrobial creams and other dressing agents used for traumatic wounds are ineffective in deep burns with eschar. The subeschar plane harbours the micro-organisms and many of these agents are not able to penetrate the eschar. Even after complete epithelisation of burn wound, remodelling phase is prolonged. It may take years for scar maturation in burns. This article emphasizes on how the pathophysiology, healing and management of a burn wound is different from that of other wounds.

    Diffusion tensor imaging (DTI) has recently evolved as valuable technique to investigate diffuse axonal injury (DAI). This study examined whether fractional anisotropy (FA) images analyzed by statistical parametric mapping (FA-SPM images) are superior to T 2 *-weighted gradient recalled echo (T2*GRE) images or fluid-attenuated inversion recovery (FLAIR) images for detecting minute lesions in traumatic brain injury (TBI) patients. DTI was performed in 25 patients with cognitive impairments in the chronic stage after mild or moderate TBI. The FA maps obtained from the DTI were individually compared with those from age-matched healthy control subjects using voxel-based analysis and FA-SPM images (p<0.001). Abnormal low-intensity areas on T2*GRE images (T2* lesions) were found in 10 patients (40.0%), abnormal high-intensity areas on FLAIR images in 4 patients (16.0%), and areas with significantly decreased FA on FA-SPM image in 16 patients (64.0%). Nine of 10 patients with T2* lesions had FA-SPM lesions. FA-SPM lesions topographically included most T2* lesions in the white matter and the deep brain structures, but did not include T2* lesions in the cortex/near-cortex or lesions containing substantial hemosiderin regardless of location. All 4 patients with abnormal areas on FLAIR images had FA-SPM lesions. FA-SPM imaging is useful for detecting minute lesions because of DAI in the white matter and the deep brain structures, which may not be visualized on T2*GRE or FLAIR images, and may allow the detection of minute brain lesions in patients with post-traumatic cognitive impairment.

    Clinical psychiatric disorders of depression, anxiety, and substance abuse are most prevalent after traumatic brain injury (TBI). Pre-clinical research has focused on depression and anxiety post-injury; however, virtually no data exist examining whether the preference for illicit drugs is affected by traumatic injury in the developing adolescent brain. Using the controlled cortical impact (CCI) model of TBI and the conditioned place preference (CPP) assay, we tested the underlying hypothesis that brain injury during adolescence exacerbates the rewarding properties of cocaine in adulthood possibly through an active inflammatory status in the mesolimbic pathway. Six-week old, C57BL/6 mice sustained a single CCI-TBI to the right somatosensory cortex. CPP experiments with cocaine began 2 weeks post-TBI. Animals receiving cocaine displayed significant place preference shifts compared to saline controls. Further, within the cocaine-experienced cohort, moderate CCI-TBI during adolescence significantly increased the preference shift in adulthood when compared to naïve controls. Additionally, persistent neuroinflammatory responses were observed in the cortex, nucleus accumbens (NAc), and ventral tegmental area post-CCI-TBI. Significant increases in both astrocytic, glial fibrillary acidic protein, and microglial, ionization basic acid 1, markers were observed in the NAc at the end of CPP testing. Moreover, analysis using focused array gene expression panels identified the upregulation of numerous inflammatory genes in moderate CCI-TBI animals, compared to naïve controls, both in the cortex and NAc at 2 weeks post-TBI, before onset of cocaine administration. These results suggest that sustaining moderate TBI during adolescence may augment the rewarding effects of psychostimulants in adulthood, possibly by induction of chronic mesolimbic neuroinflammation.

    Preliminary studies of body therapy for women in trauma recovery suggest positive results but are not specific to women with post-traumatic stress disorder (PTSD) and chronic pain. To examine the feasibility and acceptability of body-oriented therapy for female veterans with PTSD and chronic pain taking prescription analgesics. A 2-group, randomized, repeated-measures design was employed. Female veterans (N=14) were recruited from a Veterans Affairs (VA) healthcare system in the Northwest United States (VA Puget Sound Health Care System, Seattle, Washington). Participants were assigned to either treatment as usual (TAU) or treatment as usual and 8 weekly individual body-oriented therapy sessions (mindful awareness in body-oriented therapy group). Written questionnaires and interviews were used to assess intervention acceptability; reliable and valid measures were administered at 3 time points to evaluate measurement acceptability and performance; and within-treatment process measures and a participant post-intervention questionnaire assessed treatment fidelity. A body-oriented therapy protocol, "Mindful Awareness in Body-oriented Therapy" (MABT) was used. This is a mind-body approach that incorporates massage, mindfulness, and the emotional processing of psychotherapy. Over 10 weeks of recruitment, 31 women expressed interest in study participation. The primary reason for exclusion was the lack of prescription analgesic use for chronic pain. Study participants adhered to study procedures, and 100% attended at least 7 of 8 sessions; all completed in-person post-treatment assessment. Written questionnaires about intervention experience suggest increased tools for pain relief/relaxation, increased body/mind connection, and increased trust/safety. Ten of 14 responded to mailed 3-month follow-up. The response-to-process measures indicated the feasibility of implementing the manualized protocol and point to the need for longer sessions and a longer intervention period

This study investigated pain sensitivity in terms of bilateral pressure pain thresholds over the trapezius and tibialis anterior muscles and pain responses after a unilateral hypertonic saline infusion into the right legs tibialis anterior muscle and related those parameters to intensity and area size of the clinical pain and to psychological factors (sleeping problems, depression, anxiety, catastrophizing and fear-avoidance). Methods Nineteen women with chronic non-traumatic neck-shoulder pain but without simultaneous anatomically widespread clinical pain (NSP) and 30 age-matched pain-free female control subjects (CON) participated in the study. Results NSP had lower pressure pain thresholds over the trapezius and over the tibialis anterior muscles and experienced hypertonic saline-evoked pain in the tibialis anterior muscle to be significantly more intense and locally more widespread than CON. More intense symptoms of anxiety and depression together with a higher disability level were associated with increased pain responses to experimental pain induction and a larger area size of the clinical neck-shoulder pain at its worst. Conclusion These results indicate that central mechanisms e.g., central sensitization and altered descending control, are involved in chronic neck-shoulder pain since sensory hypersensitivity was found in areas distant to the site of clinical pain. Psychological status was found to interact with the perception, intensity, duration and distribution of induced pain (hypertonic saline) together with the spreading of clinical pain. The duration and intensity of pain correlated negatively with pressure pain thresholds. PMID:21992460

    The aim of this study was to assess the characteristics of neuropathic pain after non-traumatic, non-compressive (NTNC) myelopathy and find potential predictors for neuropathic pain. We analyzed 54 patients with NTNC myelopathy. The Short Form McGill Pain Questionnaire (SF-MPQ) and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) were used to assess pain. Health-related QOL was evaluated by the Short Form 36-item (SF-36) health survey. Out of 48 patients with pain, 16 (33.3%) patients experienced neuropathic pain. Mean age was significantly lower in patients with neuropathic pain than in patients with non-neuropathic pain (39.1 ± 12.5 vs. 49.8 ± 9.3, P = 0.002). There were no statistically significant differences in the other variables including sex, etiology of myelopathy, pain and QOL scores between the two groups. A binary logistic regression revealed that onset age under 40, and non-idiopathic etiology were independent predictors of the occurrence of neuropathic pain. Both SF-MPQ and LANSS scores were significantly correlated with SF-36 scores, adjusted by age, sex, presence of diabetes mellitus, and current EDSS scores (r = -0.624, P Neuropathic pain must be one of serious complications in patients with NTNC myelopathy and also affects their quality of life. Onset age and etiology of myelopathy are important factors in the development of neuropathic pain in NTNC myelopathy.

    NeuroQuant® is a recently developed, FDA-approved software program for measuring brain MRI volume in clinical settings. The aims of this study were as follows: (1) to examine the test-retest reliability of NeuroQuant®; (2) to test the hypothesis that patients with mild traumatic brain injury (TBI) would have abnormally rapid progressive brain atrophy; and (3) to test the hypothesis that progressive brain atrophy in patients with mild TBI would be associated with vocational outcome. Sixteen patients with mild TBI were compared to 20 normal controls. Vocational outcome was assessed with the Glasgow Outcome Scale-Extended (GOSE) and Disability Rating Scale (DRS). NeuroQuant® showed high test-re-test reliability. Patients had abnormally rapid progressive atrophy in several brain regions and the rate of atrophy was associated with inability to return to work. NeuroQuant®, is a reliable and valid method for assessing the anatomic effects of TBI. Progression of atrophy may continue for years after injury, even in patients with mild TBI.

    The hypotheses of this systematic review were the following: 1) Prevalence of post-traumatic stress disorder (PTSD) will differ between various types of chronic pain (CP), and 2) there will be consistent evidence that CP is associated with PTSD. Of 477 studies, 40 fulfilled the inclusion/exclusion criteria of this review and were grouped according to the type of CP. The reported prevalence of PTSD for each grouping was determined by aggregating all the patients in all the studies in that group. Additionally all patients in all groupings were combined. Percentage of studies that had found an association between CP and PTSD was determined. The consistency of the evidence represented by the percentage of studies finding an association was rated according to the Agency for Health Care Policy and Research guidelines. Grouping PTSD prevalence differed ranging from a low of 0.69% for chronic low back pain to a high of 50.1% in veterans. Prevalence in the general population with CP was 9.8%. Of 19 studies, 16 had found an association between CP and PTSD (84.2%) generating an A consistency rating (consistent multiple studies). Three of the groupings had an A or B (generally consistent) rating. The veterans grouping received a C (finding inconsistent) rating. The results of this systematic review confirmed the hypotheses of this review. © 2016 American Academy of Pain Medicine. All rights reserved.

  14. Combination therapy of human umbilical cord blood cells and granulocyte colony stimulating factor reduces histopathological and motor impairments in an experimental model of chronic traumatic brain injury.

    Directory of Open Access Journals (Sweden)

    Sandra A Acosta

    Full Text Available Traumatic brain injury (TBI is associated with neuro-inflammation, debilitating sensory-motor deficits, and learning and memory impairments. Cell-based therapies are currently being investigated in treating neurotrauma due to their ability to secrete neurotrophic factors and anti-inflammatory cytokines that can regulate the hostile milieu associated with chronic neuroinflammation found in TBI. In tandem, the stimulation and mobilization of endogenous stem/progenitor cells from the bone marrow through granulocyte colony stimulating factor (G-CSF poses as an attractive therapeutic intervention for chronic TBI. Here, we tested the potential of a combined therapy of human umbilical cord blood cells (hUCB and G-CSF at the acute stage of TBI to counteract the progressive secondary effects of chronic TBI using the controlled cortical impact model. Four different groups of adult Sprague Dawley rats were treated with saline alone, G-CSF+saline, hUCB+saline or hUCB+G-CSF, 7-days post CCI moderate TBI. Eight weeks after TBI, brains were harvested to analyze hippocampal cell loss, neuroinflammatory response, and neurogenesis by using immunohistochemical techniques. Results revealed that the rats exposed to TBI treated with saline exhibited widespread neuroinflammation, impaired endogenous neurogenesis in DG and SVZ, and severe hippocampal cell loss. hUCB monotherapy suppressed neuroinflammation, nearly normalized the neurogenesis, and reduced hippocampal cell loss compared to saline alone. G-CSF monotherapy produced partial and short-lived benefits characterized by low levels of neuroinflammation in striatum, DG, SVZ, and corpus callosum and fornix, a modest neurogenesis, and a moderate reduction of hippocampal cells loss. On the other hand, combined therapy of hUCB+G-CSF displayed synergistic effects that robustly dampened neuroinflammation, while enhancing endogenous neurogenesis and reducing hippocampal cell loss.

    Childhood and adolescence coincide with rapid maturation and synaptic reorganization of distributed neural networks that underlie complex cognitive-affective behaviors. These regions, referred to collectively as the 'social brain network' (SBN) are commonly vulnerable to disruption from pediatric traumatic brain injury (TBI); however, the mechanisms that link morphological changes in the SBN to behavior problems in this population remain unclear. In 98 children and adolescents with mild to severe TBI, we acquired 3D T1-weighted MRIs at 2-8 weeks post-injury. For comparison, 33 typically developing controls of similar age, sex and education were scanned. All participants were assessed on measures of Theory of Mind (ToM) at 6 months post-injury and parents provided ratings of behavior problems at 24-months post-injury. Severe TBI was associated with volumetric reductions in the overall SBN package, as well as regional gray matter structural change in multiple component regions of the SBN. When compared with TD controls and children with milder injuries, the severe TBI group had significantly poorer ToM, which was associated with more frequent behavior problems and abnormal SBN morphology. Mediation analysis indicated that impaired theory of mind mediated the prospective relationship between abnormal SBN morphology and more frequent chronic behavior problems. Our findings suggest that sub-acute alterations in SBN morphology indirectly contribute to long-term behavior problems via their influence on ToM. Volumetric change in the SBN and its putative hub regions may represent useful imaging biomarkers for prediction of post-acute social cognitive impairment, which may in turn elevate risk for chronic behavior problems. © The Author (2016).

    To investigate the diagnostic efficacy of morphological sequences at 3.0 T MR imaging in detecting anterior cruciate ligament (ACL), meniscal pathology and traumatic cartilage legions in young patients with chronic deficient anterior cruciate ligament knees. This prospective study included 43 patients (39 male) between the age of 15 and 37 years (mean age 22.6 years) with a history of knee injury sustained at least 3 months prior to the decision to repair a torn ACL. All patients underwent a 3.0 T MR scan with the same standard protocol, including intermediate-weighted and three-dimensional spoiled gradient-recalled T1-weighted sequences with fat saturation and subsequently surgical reconstruction of the ACL, along with meniscal and cartilage repair, when necessary. All ACL tears were correctly interpreted by 3.0 T MR images. The sensitivity of the MR scans regarding tears of the medial meniscus was 93.7%, the specificity 92.6%, the positive predictive value 88.2% and the negative predictive value 95.8%. The sensitivity of the MR scans regarding tears of lateral meniscus was 85.7%, the specificity was 93.1%, the positive predictive value 85.7% and the negative predictive value 93.1%. With regard to the grading of the cartilage lesions, Cohen's kappa coefficient indicated moderate agreement for grade I and II cartilage lesions (0.5), substantial agreement for grade III and IV cartilage lesions (0.70 and 0.66) and substantial agreement for normal regions (0.75). Regarding location of the cartilage lesions, Cohen's kappa coefficient varied between almost perfect agreement in the lateral femoral condyle and no agreement in the trochlea. In the setting of chronic ACL deficiency, MR imaging at 3.0 T achieves satisfactory diagnostic performance regarding meniscal and ligamentous pathology. In the detection of cartilage lesions MRI is less successful. (orig.)

    Full Text Available It has been demonstrated that automated locomotor training can improve walking capabilities in spinal cord-injured subjects but its effectiveness on brain damaged patients has not been well established. A possible explanation of the discordant results on the efficacy of robotic training in patients with cerebral lesions could be that these patients, besides stimulation of physiological motor patterns through passive leg movements, also need to train the cognitive aspects of motor control. Indeed, another way to stimulate cerebral motor areas in paretic patients is to use the cognitive function of motor imagery. A promising possibility is thus to combine sensorimotor training with the use of motor imagery. The aim of this paper is to assess changes in brain activations after a combined sensorimotor and cognitive training for gait rehabilitation. The protocol consisted of the integrated use of a robotic gait orthosis prototype with locomotor imagery tasks. Assessment was conducted on two patients with chronic traumatic brain injury and major gait impairments, using functional magnetic resonance imaging. Physiatric functional scales were used to assess clinical outcomes. Results showed greater activation post-training in the sensorimotor and supplementary motor cortices, as well as enhanced functional connectivity within the motor network. Improvements in balance and, to a lesser extent, in gait outcomes were also found.

    Here a case is presented of a 51-year-old former high school football player with multiple concussions, including one episode with loss of consciousness. The patient experienced 6 years of cognitive and mood decline, and his wife corroborated increasing memory loss, attentional difficulties, and depressed mood without suicidal ideation. He had been unable to maintain full-time employment because of progressive decline. Based on his presentation, he had been previously diagnosed with attention deficit hyperactivity disorder and bipolar disorder, type II. Neuropsychological tests indicated domain-specific cognitive impairment, and longitudinal volumetric magnetic resonance imaging (MRI) of the brain showed progressive brainstem, diencephalic, and frontal lobe atrophy. This regional volume loss correlated with the increased signal seen on tau and amyloid imaging (FDDNP-PET scan) of a separate case of suspected chronic traumatic encephalopathy (CTE). Visual assessment of the MRI also showed evidence of old petechial hemorrhages in the frontal and temporal-parietal lobe white matter. This case raises the possibility of distinct quantitative and visual brain MRI findings in suspected CTE. Copyright © 2016 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

    The aim of this study was to explore the phenomenon of identity change and subsequent post-traumatic growth (PTG) in individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Ten participants (average illness duration 7.4 years) were interviewed (average length, 79 minutes) via a semi-structured interview schedule and verbatim transcriptions were analysed with interpretative phenomenological analysis. The four superordinate themes revealed were 'comparisons of past to present self: "you have to be someone else, and you have to live with that''', 'the effect of social isolation on identity and subsequent insights into others' behaviours', 'contemplation of future and identity: ''where do I go from here?"', and 'PTG: "the letting go, the building up, [and] the gradual process of rebuilding"'. These themes outlined the experiences of those with ME/CFS as they underwent changes in identity due to the limitations the condition imposed on activities and roles, understanding others' behaviours after a period of isolation, the comparison of the past self with the present self and finally, the positive growth that was noted by two of the interviewees with regards to a new 'true' self. Despite the distressing and unpredictable nature of ME/CFS, it appears that individuals with this disorder can experience personal growth.

    To evaluate the clinical utility of quantitative diffusion tensor tractography (DTT) and tractography-based core analysis (TBCA) of the cingulum by defining the reproducibility, normal values, and findings in traumatic brain injury (TBI). Eighty patients with TBI and normal routine MRI and 78 controls underwent MRI at 3T. To determine reproducibility, 12 subjects were scanned twice. Superior (SC) and inferior (IC) cingulum were analyzed separately by DTT (fractional anisotropy (FA) thresholds 0.15 and 0.30). TBCA was performed from volumes defined by tractography with gradually changed FA thresholds. FA values were correlated with clinical and neuropsychological data. The lowest coefficient of variation was obtained at DTT threshold 0.30 (2.0 and 2.4 % for SC and IC, respectively), but in proportion to standard deviations of normal controls, the reproducibility of TBCA was better in SC and similar to that of DTT in IC. In patients with TBI, volume reduction with loss of peripheral fibers was relatively common; mean FA was mostly normal in these tractograms. The frequency of FA reductions (>2 SD) was in DTT smaller than in TBCA, in which FA decrease was present in 42 (13.1 %) of the 320 measurements. Central FA values in SC predicted visuoperceptual ability, and those in left IC predicted cognitive speed, language, and communication ability (p < 0.05). Tractography-based measurements have sufficient reproducibility for demonstration of severe abnormalities of the cingulum. TBCA is preferential for clinical FA analysis, because it measures corresponding areas in patients and controls without inaccuracies due to trauma-induced structural changes. (orig.)

    Deep partial and full thickness facial burns require early skin grafting. Pressure face masks and local steroids reduce hypertrophic scarring. Split skin and Z-plasties are used for early reconstructive surgery. Only after softening of the scar tissue definite reconstructive work should be undertaken. For this period full thickness skin grafts and local flaps are preferred. Special regional problems require skilled plastic surgery. Reconstructive surgery is the most essential part of the rehabilitation of severe facial burns.

    To update critical care practitioners on the recent advancements in burn care. Particular topics discussed include airway management, acute resuscitation, issues within the intensive care unit, nutrition, and wound management. This is a concise review of the recent burn literature tailored to the critical care practitioner. Criteria for extubation of burn patients are examined, as is the need for cuffed endotracheal tubes in pediatric burn patients. Strategies to avoid over-resuscitation are discussed, including use of colloid, as well as nurse-driven and computer-guided resuscitation protocols. New data regarding common ICU issues such as insulin therapy, delirium, and preferred intravenous access are reviewed. The importance of nutrition in the burn patient is emphasized, particularly early initiation of enteral nutrition, continuation of nutrition during surgical procedures, and use of adjuncts such as immunonutrition and beta blockade. Finally, both short-term and long-term wound issues are addressed via sections on laser Doppler assessment of burns and pressure garment therapy to prevent long-term scarring.

    Because of their extensive wounds, burn patients are chronically exposed to inflammatory mediators. Thus, burn patients, by definition, already have "systemic inflammatory response syndrome." Current definitions for sepsis and infection have many criteria (fever, tachycardia, tachypnea, leukocytosis) that are routinely found in patients with extensive burns, making these current definitions less applicable to the burn population. Experts in burn care and research, all members of the American Burn Association, were asked to review the literature and prepare a potential definition on one topic related to sepsis or infection in burn patients. On January 20, 2007, the participants met in Tucson, Arizona to develop consensus for these definitions. After review of the definitions, a summary of the proceedings was prepared. The goal of the consensus conference was to develop and publish standardized definitions for sepsis and infection-related diagnoses in the burn population. Standardized definitions will improve the capability of performing more meaningful multicenter trials among burn centers.

    The injection of polymethylmethacrylate (PMMA) is a minimally invasive image-guided procedure that is typically used to treat vertebral body fractures due to osteoporosis or neoplastic involvement. The injection of PMMA into various other locations including the sacrum, acetabulum, pedicles, femur and tibia has been reported previously, and these procedures have, overall, been highly effective at alleviating pain and discomfort. Although the injection of PMMA into the vertebral body is a very common procedure that has been performed for over 2 decades for the percutaneous treatment of vertebral body fractures, the percutaneous injection of PMMA has not been reported in the English literature as treatment for superior pubic ramus fractures. We report the percutaneous treatment of an acute superior pubic ramus fracture and of a chronic insufficiency fracture of the superior pubic ramus using a parasymphyseal approach to access the region of injury.

    Neurogenic dysphagia is a difficulty in swallowing induced by nervous system disease. It often causes serious complications, which are preventable if dysphagia is properly managed. There is growing debate concerning the usefulness of non-invasive neuromuscular electrical stimulation (NMES) in treating swallowing dysfunction. Aim of this study was to assess the effectiveness of Vitalstim© device, and to investigate the neurophysiological mechanisms underlying functional recovery. A 34-year-old man, affected by severe chronic dysphagia following traumatic brain injury, underwent two different intensive rehabilitation trainings, including either conventional rehabilitation alone or coupled to Vitalstim training. We evaluated patient swallowing function in two separate sessions (i.e. before and after the two trainings) by means of ad hoc swallowing function scales and electrophysiological parameters (rapid paired associative stimulation). The overall Vitalstim program was articulated in 6 weekly sessions for 6 weeks. The patient did not report any side-effect either during or following both the intensive rehabilitation trainings. We observed an important improvement in swallowing function only after Vitalstim training. In fact, the patient was eventually able to safely eat even solid food. This is the first report objectively suggesting (by means of rPAS) a correlation between the brain neuroplastic changes induced by Vitalstim and the swallowing function improvement. It is hypothesizable that Vitalstim may have targeted cortical (and maybe subcortical) brain areas that are recruited during the highly coordinated function of swallowing, and it may have thus potentiated the well-known neuroplastic changes induced by repetitive and intensive swallowing exercises, probably thanks to metaplasticity phenomena.

    Full Text Available Background: In more than 90% of whiplash accidents a good explanation regarding the association between trauma mechanism, organic pathology, and persistent symptoms has failed to be provided. Objective: We predicted that the severity of chronic whiplash-associated disorder (WAD, measured as number of whiplash symptoms, pain duration, pain-related disability, and degree of somatisation would be associated with the number of post-traumatic stress disorder symptoms (PTSD. Secondly, we expected attachment-anxiety to be a vulnerability factor in relation to both PTSD and WAD. Design: Data were collected from 1,349 women and 360 men suffering from WAD from the Danish Society for Polio, Traffic, and Accident Victims. The PTSD symptoms were measured by the Harvard Trauma Questionnaire. All three core PTSD clusters were included: re-experiencing, avoidance, and hyperarousal. Attachment security was measured along the two dimensions, attachment-anxiety and attachment-avoidance, by the Revised Adult Attachment Scale. Results: PTSD symptoms were significantly related to the severity of WAD. In particular, the PTSD clusters of avoidance and hyperarousal were associated with the number of whiplash symptoms, disability, and somatisation. Attachment-anxiety was significantly related to PTSD symptoms and somatisation but not to pain and disability. A co-morbidity of 38.8% was found between the PTSD diagnosis and WAD, and about 20% of the sample could be characterised as securely attached. Conclusions: The PTSD clusters of avoidance and hyperarousal were significantly associated with severity of WAD. The study emphasises the importance of assessing PTSD symptomatology after whiplash injury. Furthermore, it highlights that attachment theory may facilitate the understanding of why some people are more prone to develop PTSD and WAD than others.For abstract or full text in other languages, please see Supplementary files under Reading Tools online

    Full Text Available Abstract Background Early trauma-focused cognitive-behavioural therapy (TFCBT holds promise as a preventive intervention for people at risk of developing chronic post-traumatic stress disorder (PTSD. The aim of this review was to provide an updated evaluation of the effectiveness of early TFCBT on the prevention of PTSD in high risk populations. Methods We performed a systematic literature search in international electronic databases (MEDLINE, EMBASE, PsycINFO, CENTRAL, CINAHL, ISI and PILOTS and included randomised controlled trials comparing TFCBT delivered within 3 months of trauma, to alternative interventions. All included studies were critically appraised using a standardised checklist. Two independent reviewers selected studies for inclusion and assessed study quality. Data extraction was performed by one reviewer and controlled by another. Where appropriate, we entered study results into meta-analyses. Results Seven articles reporting the results of five RCTs were included. All compared TFCBT to supportive counselling (SC. The study population was patients with acute stress disorder (ASD in four trials, and with a PTSD diagnosis disregarding the duration criterion in the fifth trial. The overall relative risk (RR for a PTSD diagnosis was 0.56 (95% CI 0.42 to 0.76, 1.09 (95% CI 0.46 to 2.61 and 0.73 (95% CI 0.51 to 1.04 at 3–6 months, 9 months and 3–4 years post treatment, respectively. A subgroup analysis of the four ASD studies only resulted in RR = 0.36 (95% CI 0.17 to 0.78 for PTSD at 3–6 months. Anxiety and depression scores were generally lower in the TFCBT groups than in the SC groups. Conclusion There is evidence for the effectiveness of TFCBT compared to SC in preventing chronic PTSD in patients with an initial ASD diagnosis. As this evidence originates from one research team replications are necessary to assess generalisability. The evidence about the effectiveness of TFCBT in traumatised populations without an ASD

    Multi-drug resistant Acinetobacter baumanii infections represent a growing problem, especially in traumatic wounds and burns suffered by military personnel injured in Middle Eastern conflicts. Effective treatment using traditional antibiotics can be extremely difficult and new antimicrobial approaches are being investigated. One of these antimicrobial alternatives could be the combination of non-toxic photosensitizers (PS) and visible light known as photodynamic therapy (PDT). We report on the establishment of a new mouse model of full thickness thermal burns infected with a bioluminescent derivative of a clinical Iraqi isolate of A. baumannii and its PDT treatment by topical application of a PS produced by covalent conjugation chlorin(e6) to polyethylenimine followed by illumination of the burn surface with red light. Application of 108 A. baumannii cells to the surface of 10-second burns made on the dorsal surface of shaved female BALB/c mice led to chronic infections that lasted on average 22 days characterized by a remarkably stable bacterial bioluminescence. PDT carried out on day 0 soon after applying bacteria gave over three logs of loss of bacterial luminescence in a light exposure dependent manner, while PDT carried out on day 1 and day 2 gave approximately a 1.7-log reduction. Application of PS dissolved in 10% or 20% DMSO without light gave only modest reduction in bacterial luminescence from mouse burns. Some bacterial regrowth in the treated burn was observed but was generally modest. It was also found that PDT did not lead to inhibition of wound healing. The data suggest that PDT may be an effective new treatment for multi-drug resistant localized A. baumannii infections.

The aim of this study was to investigate the existence of post-traumatic stress disorder (PTSD and predictors of PTSD Checklist score initially and 3 months after injury in burns victims admitted to the Sina Burn Center in north-west Iran.Methods: This prospective study examined adult patients aged 16–65 years with unintentional burns. The PTSD Checklist was used to screen for PTSD.Results: Flame burns constituted 49.4% of all burns. Mean PTSD score was 23.8 ± 14.7 early in the hospitalization period and increased to 24.2 ± 14.3, 3 months after the burn injury. Twenty percent of victims 2 weeks into treatment had a positive PTSD screening test, and this figure increased to 31.5% after 3 months. The likelihood of developing a positive PTSD screening test increased significantly after 3 months (P < 0.01. Using multivariate regression analysis, factors independently predicting PTSD score were found to be age, gender, and percentage of total body surface area burned.Conclusion: PTSD was a problem in the population studied and should be managed appropriately after hospital admission due to burn injury. Male gender, younger age, and higher total body surface area burned may predict a higher PTSD score after burn injury. Keywords: post-traumatic stress disorder, burn injury, predictors, Iran

    Full Text Available Traumatic brain injury is the first cause of death and disability in children and young adults in worldwide. During the acute phase of recovery from moderate to severe brain injury, a period of post-traumatic confusion state (PTCS will arise that is a combination of cognitive and behavioral dysfunction. Seven key symptoms of PTCS are identified and measured by Confusion Assessment Protocol (CAP  Agitation can be part of PTCS in the acute phase or, part of the recovery of consciousness in chronic phase. There are different hypothesis and classifications of acute and chronic post-traumatic aggressive syndromes. While post-traumatic aggression is common, its mechanism, assessment tool, outcome and treatment plans are not well-defined. Understanding the different aspects of post-traumatic aggression; mechanism, differential diagnosis, and treatment are reviewed in this article.

    Thermal burn injuries are a significant cause of morbidity and mortality worldwide. In addition to treatment of the burns, emergency clinicians must assess for inhalation injury, exposure to toxic gases, and related traumatic injuries. Priorities for emergency resuscitation include stabilization of airway and breathing, intravenous fluid administration, pain control, and local wound care. Special populations, including children and pregnant women, require additional treatment considerations. Referral to specialized burn care for select patients is necessary to improve long-term outcomes. This article reviews thermal burn classification and evidence-based treatment strategies.

The scope of this qualitative theory was increased by formalizing the connections between 14 individual studies all conducted by the same researcher on the same topic, with different groups, using different research designs and different types of analyses. Axioms were derived from this research program along with attributes of traumatic childbirth, posttraumatic stress, and secondary traumatic stress. This middle range theory addresses the long-term chronic consequences of a traumatic birth for mothers including its impact on breastfeeding, subsequent childbirth, and the anniversary of birth trauma. The impact on fathers and clinicians present at the traumatic birth is highlighted as secondary traumatic stress comes into play. Troubling glimpses of difficulties in mother–infant bonding are revealed. PMID:28462301

    The diagnosis PTSD does not adequately describe the impact of exposure to childhood trauma of the developing child. The objective of the study was to examine the prevalence of different interpersonal trauma types and to describe the long-term effects of maltreatment and neglect in a clinical sample of 34 adolescents. The majority (62%) of the sample was exposed to two different types of trauma during childhood. Emotional abuse and emotional neglect have been the most common trauma types (59%; 53%). 71% of the traumatized adolescents did not meet the criteria for PTSD. The most common diagnosis in the sample was Borderline Personality Disorder. All average scores at SCL-90-Symptom-Scale were clinical significant. Half of the sample reported suicide attempts and self destructive behavior. One third reported substance abuse and aggressive behavior against others respectively. None of the traumatized adolescents had a positive Self-concept. Altogether the results show that abused children and adolescents have a range of psychological sequelae that are not captured in the PTSD diagnostic criteria. Therefore the results support the necessity for a new and more precise diagnosis for chronically traumatized children and adolescents.

  9. Burning mouth syndrome: Current concepts

    Full Text Available Burning mouth syndrome (BMS is a chronic pain condition. It has been described by the International Headache Society as "an intra-oral burning or dysesthetic sensation, recurring daily for more than 2 h/day for more than 3 months, without clinically evident causative lesions." BMS is frequently seen in women in the peri-menopausal and menopausal age group in an average female/male ratio of 7:1. The site most commonly affected is the anterior two-thirds of the tongue. The patient may also report taste alterations and oral dryness along with the burning. The etiopathogenesis is complex and is not well-comprehended. The more accepted theories point toward a neuropathic etiology, but the gustatory system has also been implicated in this condition. BMS is frequently mismanaged, partly because it is not well-known among healthcare providers. Diagnosis of BMS is made after other local and systemic causes of burning have been ruled out as then; the oral burning is the disease itself. The management of BMS still remains a challenge. Benzodiazepines have been used in clinical practice as the first-line medication in the pharmacological management of BMS. Nonpharmacological management includes cognitive behavioral therapy and complementary and alternative medicine (CAM. The aim of this review is to familiarize healthcare providers with the diagnosis, pathogenesis, and general characteristics of primary BMS while updating them with the current treatment options to better manage this group of patients.

    Full Text Available Objective: Psychiatric rehabilitation has gained significance owing to improved healthcare facilities for burn injuries and decreased mortality/ morbidity rates. Burn traumas may result in psychiatric signs such as denial, anger, guilt, confusion, disgrace, anxiety, distress, and nervousness. Psychiatric disorders such as delirium, depression, anxiety, post-traumatic stress disorder, and sexual problems can also be encountered. Therefore, it is necessary to look for these signs and disorders through regular sessions with burn patients and appropriate psychometric tests. This study aims at examining the process of psychological rehabilitation for burn patients in light of the current literature. Material and Methods: This study has been carried out in the light of the main and current literature review. The study intends to put forth the data observed in the course of the psychological diagnosis, treatment and rehabilitation of burn patients. The study has been conducted in accordance with the Helsinki Declaration Guidelines. Results: Treatment and rehabilitation process requires a multidisciplinary teamwork that consists of physicians, dieticians, psychologists, social service specialists, and other healthcare workers who can meet the needs of burn patients and their families. It is necessary for the team to contribute both to the hospitalization process and the social environment of the patients and their families. Conclusion: It is observed that the quality of life of these patients can be considerably improved with the effective assessment of psychiatric signs that occur during or after the injury and with appropriate treatment methods.

    Partial-thickness scalds are the most common pediatric burn injury, and primary management consists of wound dressings to optimize the environment for reepithelialization. Operative intervention is reserved for burns that fail to heal using conservative methods. Worldwide, paraffin-based gauze (Jelonet) is the most common burn dressing; but literature suggests that it adheres to wounds and requires more frequent dressing change that may traumatize newly epithelialized surfaces. Hydrocolloid dressings (DuoDERM) provide an occlusive moist environment to optimize healing and are associated with less frequent dressing changes.

    Full Text Available BACKGROUND With the advances in technology, electrical injuries are becoming more common and are the leading cause of work-related traumatic death. One third of all electrical traumas and most high-voltage injuries are job related and more than 50% of these injuries result from power line contact. The management of the major burn injury represents a significant challenge to every member of the burns team. Most of electrical burns present with gangrene of toes and limbs with eschar over body parts. Their presentation is mostly due to contact with high-voltage electricity at their work places. MATERIALS AND METHODS A retrospective study was made to study the clinico-social profile of patients suffering electric burns admitted into Department of General Surgery. RESULTS 92 cases were evaluated and studied. Majority of patients developed gangrene of limbs and toes. Amputations and skin grafting was done. Most patients who suffered electric burns were males of age group 21 to 40 years. All cases are accidental and mostly occurred at work places. Most electric burns are high-voltage based and caused deep burns. Major complications like acute renal failure and septicaemia were encountered. Most of them suffered 16 to 30% burns. Most commonly isolated organism from wounds is pseudomonas. Most of them suffered a hospital stay of 1 to 2 months. CONCLUSION Electric burns are a burden to the society. Prevention is the best way to deal with them. Electricity-based employees have to be trained properly regarding safety measures to be taken. General education of public regarding safety measures can prevent electrical burn injuries.

    To examine structural integrity loss in the fornix from 5-30 months after moderate and severe traumatic brain injury (TBI) using diffusion tensor imaging. MRIs were prospectively undertaken in 29 adults with moderate and severe TBI at two time points. Fractional anisotropy (FA) was calculated for the fornix (column/body, right crux and left crux) at 5 and 30 months post-injury. Paired t-tests revealed significant FA reductions with large effect sizes across time in the column/body, p fornix plays a critical role in memory, this may be a contributing factor to the poor clinical outcomes observed in these patients.

    Although burn patients with preexisting mood disorders have been shown to have diminished clinical recovery, acute mental disorders (AMD) are often unrecognized despite a link with post-traumatic stress disorder and social maladjustment later on. This study assessed the clinical profile of a large cohort of burn patients who developed AMD compared to those with chronic mental illness (CMI) and those without mental health problems to assess the impact of AMI on burn outcomes. Admission data on 96,451 patients with third degree flame burns was abstracted from the Nationwide Inpatient Sample (NIS) Database from 2001 to 2011. AMD was defined as adjustment disorder (ICD-10 codes F43.2-F43.29) and acute stress disorder (F43.0), while CMI was defined as major depressive disorder (F33.0-F33.9) and bipolar disorder (F31.0-F31.9). Data was compared across three subgroups: AMD, CMI, and patients without any mood disorders. Categorical variables were compared using the Chi-square test, and continuous variables were compared using Student t-test and analysis of variance (ANOVA). Multivariate analysis using the "backward Wald" method was performed to calculate odds ratios (OR) and determine independent factors which increased the risk of developing AMD after burn. 979 (1%) burn patients were diagnosed with AMD, compared to 5971 (6.2%) with CMI and 89,501 (92.8%) without mood disorders at the time of the burn. Patients with AMD were significantly younger, predominantly male and Caucasian. Patients with AMD had a higher frequency of multiple third-degree burn sites. AMD patients had a significantly longer length of hospitalization and shorter actuarial survival. More AMD patients lacked social or family support, suffered from alcoholism or illicit drug abuse, and had a history of psychological trauma or self-inflicted injuries compared to other groups. After burn, 4.9% of AMD patients developed burn wound infections, 5.0% had nutritional deficiencies, 1.7% had skin graft failure

    The improvement of preclinical emergency medicine, better surgical and conservative therapies, and the development of intensive care units and specialized centers have improved the survival rate for patients with serious spinal cord injuries. Therefore, more sequelae of chronic spinal cord injuries such as post-traumatic spinal cord cavitations also occur. The first such case was described by Bastian in 1867. Generally, these cavitations were diagnosed from 2 months up to 32 years after the trauma. The overall prevalence of post-traumatic syringomyelia (PTS) is not known; however, with the increasing use of magnetic resonance imaging (MRI), its diagnosis has increased, ranging from 2.3% of paraplegic and tetraplegic patients in 1976 and 3.2% in 1985, to nearly 50% in a selected group of patients in 1991 and 1993. In 1995, a 4.45% incidence was reported. In our clinic we are currently treating 440 cases of syringomyelia, 140 of which are PTS. Several observations suggest more than one potential mechanism for the evolution of a post-traumatic cyst or PTS. Various factors, such as hemorrhage or, in particular, ischemia within the spinal cord, blockage of the cerebrosinal fluid (CSF) pathways around the cord or localized meningeal fibrosis either alone or in combination with other factors, may be involved. Clinically, sensory disturbances, loss of motor function, pain, and modification of the deep tendon reflexes are observed in most patients. On MRI, PTS is seen as a longitudinal, cystic cavity within the spinal cord, giving a hypointense signal on T 1 -weighted images and a hyperintense signal on T 2 -weighted images. For treatment planning it is mandatory to identify the lower and upper end of the PTS on the MRI. (orig.) [de

    Hair bleaching is increasingly being carried out in hairdressing salons. The products used are a mixture of hydrogen peroxide and persulfates, both active chemical agents. Scalp burns secondary to hair bleaching are a traumatic adverse effect rarely discussed in publications that continue to be little known among healthcare professionals. We report the case of a 15-year-old girl with a plaque of scarring alopecia on the vertex. This lesion resulted from a deep burn following a hair-bleaching procedure. Healing took around 4 months, resulting in discomfort for our patient. This is a rare case of scarring alopecia following a basic chemical burn to the scalp. The oxidation reaction induced by the mixture of hydrogen peroxide and persulfates, prepared in a basic medium, causes bleaching of the melanin pigments in hair. The clinical presentation of a single, well limited, painful, oozing ulceration located at the vertex was similar to the other cases published in the literature. Although a chemical burning mechanism is most often incriminated, the procedure is always coupled with use of a heat source and associated thermal burn may occur. The delayed appearance of the lesion appears to be caused by the forming of surfactants by the hydrogen peroxide/persulfate mixture, resulting in slow dissolution of the oxidizing compounds within the stratum corneum.

    Full Text Available Traumatic injury of the diaphragm ranges from 0.6 to 1.2% and rise up to 5%among patients who were victims of blunt trauma and underwent laparotomy.Clinical suspicion associated with radiological assessment contributes to earlydiagnosis. Isolated diaphragmatic injury has a good prognosis. Generallyworse outcomes are associated with other trauma injuries. Bilateral andright diaphragmatic lesions have worse prognosis. Multi detector computed tomography (MDCT scan of the chest and abdomen provides better diagnosticaccuracy using the possibility of image multiplanar reconstruction. Surgicalrepair via laparotomy and/ or thoracotomy in the acute phase of the injury hasa better outcome and avoids chronic complications of diaphragmatic hernia.The authors present the case of a young male patient, victim of blunt abdominaltrauma due to motor vehicle accident with rupture of the diaphragm, spleenand kidney injuries. The diagnosis was made by computed tomography of thethorax and abdomen and was confirmed during laparotomy.

    Background: Burning feet syndrome (BFS) has been described anecdotally in the literature for over 200 years. Described subjectively by patients as burning, prickling and unremitting with nocturnal exacerbations, the condition draws parallels with the burning dysaesthesia found in diabetic peripheral neuropathy, and appears to display a similar chronicity. Despite being a common symptom, especially among the elderly, its etiology in non-specific and often marked by a lack of objective clinical...

    In human body, wound healing is a normal biological phenomenon. Burns may be acute or chronic depending upon the source and its time of exposure. Burn wounds may be superficial, partial or full thickness wounds. When skin comes in contact with higher temperature, protein denaturation takes place due to which the plasma membrane integrity is lost. When skin is burned, a number of inflammatory mediators and releasing agents such as histamine, nitric oxide, oxygen free radicals, eicosanoid produ...

    Burning mouth syndrome (BMS) refers to chronic orofacial pain, unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women. BMS is characterized by an intense burning or stinging sensation, preferably on the tongue or in other areas of the oral mucosa. It can be accompanied by other sensory disorders such as dry mouth or taste alterations. Probably of multifactorial origin, and often idiopathic, with a still unknown etiopathogenesis in which local, systemic and psychological factors are implicated. Currently there is no consensus on the diagnosis and classification of BMS. This study reviews the literature on this syndrome, with special reference to the etiological factors that may be involved and the clinical aspects they present. The diagnostic criteria that should be followed and the therapeutic management are discussed with reference to the most recent studies.

    Introduction. The key element of a safe workplace for employees is the maintenance of fire safety. Thermal, chemical, and electrical burns are common types of burns at the workplace. This study assessed the epidemiology of work-related burn injuries on the basis of the workers treated in a regional burn centre. Methods. Two years' retrospective data (2005-2006) from the Trauma Registry of the American College of Surgeons of the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Georgia, were collected and analysed. Results. During the time period studied, 2510 adult patients with acute burns were admitted; 384 cases (15%) were work-related. The average age of the patients was 37 yr (range, 15-72 yr). Males constituted the majority (90%) of workrelated burn injury admissions. The racial distribution was in accordance with the Centre's admission census. Industrial plant explosions accounted for the highest number of work-related burns and, relatively, a significant number of patients had chemical burns. The average length of hospital stay was 5.54 days. Only three patients did not have health insurance and four patients (1%) died. Conclusion. Burn injuries at the workplace predominantly occur among young male workers, and the study has shown that chemical burns are relatively frequent. This study functions as the basis for the evaluation of work-related burns and identification of the causes of these injuries to formulate adequate safety measures, especially for young, male employees working with chemicals.

    Sustaining a burn injury sets in motion a cycle of pain, disfigurement, and a search for survival. In pediatric burns, the injury extends to the parents where fear, ignorance, and helplessness forever change their lives. Pediatric burn injuries are caused by fire, hot liquids, clothing irons, hair curlers, caustic substances like drain cleaner, the grounding of an electrical source, and exposure to radiation. Efficiency in the delivery of pediatric burn care is critical. Maximizing resource utilization means continual self-evaluation and economic analysis of therapeutic modalities. Griffiths et al found that most childhood burns are due to scalds, which can be treated for $1061 per percent burn. Paddock et al reduced the cost of treating superficial pediatric burns and reduced the length of stay in hospital using silver-impregnated gauze over traditional methods. Barrett et al found improved cosmesis of skin grafts using cultured epithelial autografts but at a substantially increased cost. Corpron et al showed that pediatric burn units that treat burns >10% total body surface area and operative treatment of pediatric burns regardless of size generate positive revenue. There is a paucity of evidentiary pediatric burn economic data. More research is needed to address areas of pediatric burn care inefficiency. Improving knowledge of cost in all health care endeavors will create competition and drive down expenditures.

    Full Text Available Background: Posttraumatic stress disorder (PTSD tends to follow a chronic and treatment resistant course. Avoidance and numbing are symptoms associated with chronicity and impaired life quality. As D-cycloserine (DCS can facilitate extinction of conditioned fear, we aimed to investigate the efficacy and tolerability of DCS for the treatment of numbing and avoidance in chronic PTSD. Materials and Methods: This was an 11-week, double-blind, cross-over trial conducted in 2012 and 2013, in out-patient University psychiatry clinics. The studied population was selected randomly among outpatients with chronic combat-related PTSD (based on DSM-IV-TR criteria for chronic PTSD, who were males over 18 and <65 years of age (n = 319. Seventy six eligible patients were randomly assigned to two groups. Patients entered a 1-week run-in period. The groups received either an add-on treatment of DCS (50 mg daily, or placebo (4-week. After a 2-week washout, the groups received cross-over treatments (4-week. Clinical, paraclinical assessments, and clinician administered PTSD scale (CAPS were performed at baseline, and at the end of the 1 st , 5 th , and 11 th week. Side-effects were also evaluated. The overall number of avoidance and numbing symptoms, symptom frequency, and symptom intensity were measured separately. Results: Neither frequency nor number of symptoms was significantly influenced. However, DCS treatment demonstrates a significant decrease in intensity of avoidance/numbing symptoms, and improvement in function (mean [standard error] = −4.2 [1.5], P = 0.008. Side-effects were not statistically remarkable. Conclusion: D-cycloserine can help as an adjunctive treatment to alleviate numbing and avoidance in combat-related chronic PTSD.

    1988-08-01

    From 1971 to 1981, 245 adults with burn injuries were admitted to the Ahmadu Bello University Hospital, Zaria. The burns were major in 197 patients, moderate in 28 and minor in 20. Socioeconomic factors contributing to the injuries included the use of wood fires for cooking, for warming the body and the dwelling during the cool harmattan season, loose indigenous garments, thatch-roofed huts, petrol hoarding and epileptic seizures. Flame burns exceeded scalds with a high seasonal frequency in both men and women during the harmattan. Scalds occurred predominantly among the women, puerperal hot baths being a major cause. The overall mortality rate of 22 per cent is excessive. General economic development, architectural improvements, proper handling of petrol and kerosene, modification or abandonment of the puerperal ritual of hot baths, the maintenance of chronic epileptics on anticonvulsants and a programme of universal active immunization against tetanus would contribute to the prevention of burns and complications in adults and decrease the mortality rate.

    Joshi, V.

    1991-01-01

    This chapter summarizes the direct biomass burning practices in India. The review pertains to fire practices in forest, agricultural fields, grasslands, households, and industry. In forest land, extent of controlled burning for regeneration and fire prevention is estimated based on the forest statistics. The biomass burned annually due to accidental fires and for shifting cultivation is quantified based on a few earlier studies. In the case of household and small-scale industries, the biomass burned is quantified by extrapolating past data on energy consumption. In addition to wood and crop residues, the use of dungcakes and charcoal is also accounted for in calculating the total amount of biofuels burned annually. Wherever possible, regional and seasonal variations in the biomass burning practices are highlighted. This exercise has led to improve the current estimates of biomass burned annually in India. The factors influencing the impact of National Programme on Improved Cookstoves (NPIC) in reducing the greenhouse gas emissions are discussed

    Partial-thickness scalds are the most common pediatric burn injury, and primary management consists of wound dressings to optimize the environment for reepithelialization. Operative intervention is reserved for burns that fail to heal using conservative methods. Worldwide, paraffin-based gauze (Jelonet) is the most common burn dressing; but literature suggests that it adheres to wounds and requires more frequent dressing change that may traumatize newly epithelialized surfaces. Hydrocolloid dressings (DuoDERM) provide an occlusive moist environment to optimize healing and are associated with less frequent dressing changes. The aim of the study was to retrospectively analyze pediatric burns in a single tertiary referral center over a 10-year period comparing the impact of Jelonet and DuoDERM dressings relative to operative intervention rates. All pediatric burns admitted between 1997 and 2007 were identified using the Hospital Inpatient Enquiry system. Demographics were collected from hospital records and theater logbooks. Acute, partial-thickness burns in patients younger than 15 years were analyzed according to dressing type applied (Jelonet or DuoDERM). Two hundred forty-eight pediatric burns were analyzed between 1997 and 2007. One hundred thirty-nine patients were treated with Jelonet dressings, and 109 were treated with DuoDERM. Debridement and grafting were required in 60 (43%) of the Jelonet patients compared with 10 (9%) of the DuoDERM patients (P pediatric burns.

    Abstract Because there is no standard reporting of injuries in jails and prisons, the national burden of head trauma during incarceration is unclear. We report on a case of repeated head trauma in the New York City (NYC) jail system, data on the incidence of head trauma and mild traumatic brain injury (mTBI), and compare those findings with national estimates. The case report revealed 64 injurious events over two years, 44% resulting in a head injury and 25% resulting in emergency hospitalization. During the 42 months of this analysis, 10,286 incidents of head trauma occurred in the NYC jail system. Mild TBI occurred in 1,507 of these instances. The rate of head trauma and mTBI was 269.0 and 39.4 per 1,000 person-years, respectively. The lack of reporting head trauma in correctional settings means that national prevalence estimates of these critical health outcomes miss the vulnerable cohort of incarcerated individuals.

    It is alarming that only 59% of those who have post-traumatic stress disorder (PTSD) respond to selective serotonin reuptake inhibitors. Many existing treatments, both pharmacological and nonpharmacological, do not directly target trauma memories that lay at the core of the PTSD pathogenesis. Notable exceptions are medications like ketamine and propranolol and trauma-focused psychotherapies like eye-movement desensitization and reprocessing therapy (developed by Shapiro) and Trauma Interventions using Mindfulness Based Extinction and Reconsolidation (TIMBER) for trauma memories (developed by Pradhan). Although the antidepressant effects of ketamine are no longer news, ketamine's effects on treatment refractory PTSD (TR-PTSD) is a recent concept. As TR-PTSD has a marked public health burden and significant limitations in terms of treatment interventions, a thorough assessment of current strategies is required. Research to bring clarity to the underlying pathophysiology and neurobiology of TR-PTSD delineating the chemical, structural, and circuitry abnormalities will take time. In the interim, in the absence of a 1-size-fits-all therapeutic approach, pragmatically parallel lines of research can be pursued using the pharmacological and nonpharmacological treatments that have a strong theoretical rationale for efficacy. This article aims to review the current literature on interventions for PTSD, most notably ketamine, trans-cranial magnetic stimulation treatment, yoga and mindfulness interventions, and TIMBER. We present an outline for their future use, alone as well as in combination, with a hope of providing additional insights as well as advocating for developing more effective therapeutic intervention for this treatment-resistant and debilitating condition.

    Traumatic brain injury (TBI) causes brain dysfunction in many patients. However, some patients have severe brain dysfunction but display no abnormalities on magnetic resonance imaging (MRI). There have been some reports of hypometabolism even in such patients. The purpose of this study was to investigate the relationship between metabolic abnormality and loss of neuronal integrity in TBI patients with some symptoms but without MRI abnormalities. The study population comprised ten patients with TBI and ten normal volunteers. All of the patients were examined at least 1 year after the injury. 15 O-labelled gas PET and [ 11 C]flumazenil (FMZ) positron emission tomography (PET) were carried out. The cerebral metabolic rate of oxygen (CMRO 2 ) and binding potential (BP) images of FMZ were calculated. Axial T2WI, T2*WI and FLAIR images were obtained. Coronal images were added in some cases. All of the patients had normal MRI findings, and all showed areas with abnormally low CMRO 2 . Low uptake on BP images was observed in six patients (60%). No lesions that showed low uptake on BP images were without low CMRO 2 . On the other hand, there were 14 lesions with low CMRO 2 but without BP abnormalities. These results indicate that there are metabolic abnormalities in TBI patients with some symptoms after brain injury but without abnormalities on MRI. Some of the hypometabolic lesions showed low BP, indicating a loss of neuronal integrity. Thus, FMZ PET may have potential to distinguish hypometabolism caused by neuronal loss from that caused by other factors. (orig.)

    This is a report of the first descriptive analytic study of a group of 183 burn patients, treated in the Burn Unit at the University Hospital of Cartagena, Colombia during the period since January 1985 until December 1990. There is presented experience with the selected group of 24 patients in whom the diagnosis of burn was associated with epilepsy. There is also analysed and described the gravity of the scars sequels, neurological disorders, the complication of the burn and an impact of this problem on the patient, his (her) family and the community. It is very important to report that there was found Neurocisticercosis in 66.6% of the group of burn patients with epilepsy, and it is probably the first risk factor of burn in this group.

    Although they are formally categorized by the ABA as major burns, isolated burns of the feet are often managed on an outpatient basis. This retrospective review evaluates the success of such outpatient management, including the complications encountered. The outcome of the review emphasizes that although isolated burns encompass only a small body surface area, they require careful in-hospital treatment to avoid the complications of cellulitis, subsequent prolonged hospitalization, increased need for skin grafting, and increased incidence of hypertrophic scarring.

    The evaluation and treatment of head and neck burns remains a challenge to the burn surgeon, because of the long-term emotional and psychologic effects of even the most minor change in facial appearance. Fortunately, the results currently achieved are orders of magnitude better than previously available, but they still remain far below the perfect outcome desired by both the physician and the burn victim.

    This study compared the difference in brain structure in 12 mine disaster survivors with chronic post-traumatic stress disorder, 7 cases of improved post-traumatic stress disorder symptoms, and 14 controls who experienced the same mine disaster but did not suffer post-traumatic stress disorder, using the voxel-based morphometry method. The correlation between differences in brain structure and post-traumatic stress disorder symptoms was also investigated. Results showed that the gray matter volume was the highest in the trauma control group, followed by the symptoms-improved group, and the lowest in the chronic post-traumatic stress disorder group. Compared with the symptoms-improved group, the gray matter volume in the lingual gyrus of the right occipital lobe was reduced in the chronic post-traumatic stress disorder group. Compared with the trauma control group, the gray matter volume in the right middle occipital gyrus and left middle frontal gyrus was reduced in the symptoms-improved group. Compared with the trauma control group, the gray matter volume in the left superior parietal lobule and right superior frontal gyrus was reduced in the chronic post-traumatic stress disorder group. The gray matter volume in the left superior parietal lobule was significantly positively correlated with the State-Trait Anxiety Inventory subscale score in the symptoms-improved group and chronic post-traumatic stress disorder group (r = 0.477, P = 0.039). Our findings indicate that (1) chronic post-traumatic stress disorder patients have gray matter structural damage in the prefrontal lobe, occipital lobe, and parietal lobe, (2) after post-traumatic stress, the disorder symptoms are improved and gray matter structural damage is reduced, but cannot recover to the trauma-control level, and (3) the superior parietal lobule is possibly associated with chronic post-traumatic stress disorder. Post-traumatic stress disorder patients exhibit gray matter abnormalities.

    Traumatic injury remains one of the most prevalent reasons for patients to be hospitalized. Burn injury accounts for 40,000 hospitalizations in the United States annually, resulting in a large burden on both the health and economic system and costing millions of dollars every year. The complications associated with postburn care can quickly cause life-threatening conditions including sepsis and multiple organ dysfunction and failure. In addition, alcohol intoxication at the time of burn injury has been shown to exacerbate these problems. One of the biggest reasons for the onset of these complications is the global suppression of the host immune system and increased susceptibility to infection. It has been hypothesized that infections after burn and other traumatic injury may stem from pathogenic bacteria from within the host's gastrointestinal tract. The intestine is the major reservoir of bacteria within the host, and many studies have demonstrated perturbations of the intestinal barrier after burn injury. This article reviews the findings of these studies as they pertain to changes in the intestinal immune system after alcohol and burn injury.

    Single, severe traumatic brain injury (TBI) which elevates CNS amyloid, increases the risk of Alzheimer's disease (AD); while repetitive concussive and subconcussive events as observed in athletes and military personnel, may increase the risk of chronic traumatic encephalopathy (CTE). We describe two clinical cases, one with a history of multiple concussions during a career in the National Football League (NFL) and the second with frontotemporal dementia and a single, severe TBI. Both patients presented with cognitive decline and underwent [(18)F]-Florbetapir positron emission tomography (PET) imaging for amyloid plaques; the retired NFL player also underwent [(18)F]-T807 PET imaging, a new ligand binding to tau, the main constituent of neurofibrillary tangles (NFT). Case 1, the former NFL player, was 71 years old when he presented with memory impairment and a clinical profile highly similar to AD. [(18)F]-Florbetapir PET imaging was negative, essentially excluding AD as a diagnosis. CTE was suspected clinically, and [(18)F]-T807 PET imaging revealed striatal and nigral [(18)F]-T807 retention consistent with the presence of tauopathy. Case 2 was a 56-year-old man with personality changes and cognitive decline who had sustained a fall complicated by a subdural hematoma. At 1 year post injury, [(18)F]-Florbetapir PET imaging was negative for an AD pattern of amyloid accumulation in this subject. Focal [(18)F]-Florbetapir retention was noted at the site of impact. In case 1, amyloid imaging provided improved diagnostic accuracy where standard clinical and laboratory criteria were inadequate. In that same case, tau imaging with [(18)F]-T807 revealed a subcortical tauopathy that we interpret as a novel form of CTE with a distribution of tauopathy that mimics, to some extent, that of progressive supranuclear palsy (PSP), despite a clinical presentation of amnesia without any movement disorder complaints or signs. A key distinguishing feature is that our patient presented

    Despite major advances in the area of burn management, burn injury continues to be a leading cause of pediatric mortality and morbidity. Facial burns in particular are devastating to the affected child and result in numerous physical and psychosocial sequelae. Although many of the principles of adult burn management can be applied to a pediatric patient with facial burns, the surgeon must be cognizant of several important differences. Facial burns and subsequent scar formation can drastically affect the growth potential of a child's face. Structures such as the nose and teeth may become deformed due to abnormal external forces caused by contractures. Serious complications such as occlusion amblyopia and microstomia must be anticipated and urgently addressed to avert permanent consequences, whereas other reconstructive procedures can be delayed until scar maturation occurs. Furthermore, because young children are actively developing the concept of self, severe facial burns can alter a child's sense of identity and place the child at high risk for future emotional and psychologic disturbances. Surgical reconstruction of burn wounds should proceed only after thorough planning and may involve a variety of skin graft, flap, and tissue expansion techniques. The most favorable outcome is achieved when facial resurfacing is performed with respect to the aesthetic units of the face. Children with facial burns remain a considerable challenge to their caregivers, and these patients require long-term care by a multidisciplinary team of physicians and therapists to optimize functional, cosmetic, and psychosocial outcomes.

  14. The multi-factorial origins of Chronic Traumatic Encephalopathy (CTE) symptomology in post-career athletes: The athlete post-career adjustment (AP-CA) model.

    Gaetz, Michael

    2017-05-01

    CTE has two prominent components: the pathophysiology that is detected in the brain postmortem and the symptomology that is present in the interval between retirement and end of life. CTE symptomology has been noted to include memory difficulties, aggression, depression, explosivity, and executive dysfunction at early stages progressing to problems with attention, mood swings, visuospatial difficulties, confusion, progressive dementia, and suicidality (e.g. McKee et al. (2012), Omalu et al. (2010a-c), McKee et al. (2009)). There are a number of assumptions embedded within the current CTE literature: The first is the assumption that CTE symptomology reported by athletes and their families is the product of the pathophysiology change detected post-mortem (e.g. McKee et al. (2009)). At present, there is little scientific evidence to suggest that all CTE symptomology is the product of CTE pathophysiology. It has been assumed that CTE pathophysiology causes CTE symptomology (Meehan et al. (2015), Iverson et al. (2016)) but this link has never been scientifically validated. The purpose of the present work is to provide a multi-factorial theoretical framework to account for the symptomology reported by some athletes who sustain neurotrauma during their careers that will lead to a more systematic approach to understanding post-career symptomology. There is significant overlap between the case reports of athletes with post-mortem diagnoses of CTE, and symptom profiles of those with a history of substance use, chronic pain, and athlete career transition stress. The athlete post-career adjustment (AP-CA) model is intended to explain some of the symptoms that athletes experience at the end of their careers or during retirement. The AP-CA model consists of four elements: neurotrauma, chronic pain, substance use, and career transition stress. Based on the existing literature, it is clear that any one of the four elements of the AP-CA model can account for a significant number of

    Full Text Available In human body, wound healing is a normal biological phenomenon. Burns may be acute or chronic depending upon the source and its time of exposure. Burn wounds may be superficial, partial or full thickness wounds. When skin comes in contact with higher temperature, protein denaturation takes place due to which the plasma membrane integrity is lost. When skin is burned, a number of inflammatory mediators and releasing agents such as histamine, nitric oxide, oxygen free radicals, eicosanoid products, tumor necrosis factors, and interleukins etc., are released at the site. For wound healing mechanism, the keratinocytes has to move from uninjured site to the burned area. For deeper burns this process takes a long time. By some unknown mechanisms, burn wounds may convert from one form to another form. So burn wound depth must be accurately measured before starting the treatment to prevent the complications. Burns can be induced in experimental animals by using different models. Many treatments such as herbal drugs, topical agents, gene therapy, volume therapy, and rehabilitation can be employed. This review article mainly deals with the theoretical and practical aspects of burn wound healing. Some burn wound healing plants with their chemical constituents, plant part used, uses and animal models are described here.

    The case of a 32-year-old woman who sustained a nasal bone fracture and dental trauma at the age of 9 is described in this article. Misdiagnosis of the dental displacement into the middle turbinate at the initial examination led to chronic facial pain. The cause of the pain was incorrectly diagnosed or misinterpreted by several medical specialists, including an otolaryngologist, neurologist, physiatrist, ophthalmologist, internist, radiologist, oral surgeon, dentist, and the patient's family physician. Finally, 23 years after the dental trauma, a multislice computed tomogram revealed that the primary maxillary canine was dislocated into the right middle nasal concha. The tooth, which had become embedded into necrotic, inflammatory tissue, was removed by endoscopic surgery, which resulted in full resolution of the patient's pain.

  17. Burns and military clothing.

    Burn injury is a ubiquitous threat in the military environment. The risks during combat are well recognised, but the handling of fuel, oil, munitions and other hot or flammable materials during peacetime deployment and training also imposes an inherent risk of accidental burn injury. Over the last hundred years, the burn threat in combat has ranged from nuclear weapons to small shoulder-launched missiles. Materials such as napalm and white phosphorus plainly present a risk of burn, but the threat extends to encompass personnel in vehicles attacked by anti-armour weapons, large missiles, fuel-air explosives and detonations/conflagrations on weapons platforms such as ships. Large numbers of burn casualties were caused at Pearl Harbor, in Hiroshima and Nagasaki, Vietnam, during the Arab/Israeli Wars and in the Falkland Islands conflict. The threat from burns is unlikely to diminish, indeed new developments in weapons seek to exploit the vulnerability of the serviceman and servicewoman to burns. Clothing can be a barrier to some types of burn--both inherently in the properties of the material, but also by trapping air between clothing layers. Conversely, ignition of the clothing may exacerbate a burn. There is hearsay that burnt clothing products within a wound may complicate the clinical management, or that materials that melt (thermoplastic materials) should not be worn if there is a burn threat. This paper explores the incidence of burn injury, the mechanisms of heat transfer to bare skin and skin covered by materials, and the published evidence for the complication of wound management by materials. Even light-weight combat clothing can offer significant protection to skin from short duration flash burns; the most vulnerable areas are the parts of the body not covered--face and hands. Multilayered combat clothing can offer significant protection for short periods from engulfment by flames; lightweight tropical wear with few layers offers little protection. Under

    An outbreak of chickenpox that occurred at the Burns Repair Surgery Unit, Department of Children's Surgery, Hospital R. del Río, between June and November, 1975, is reported. 27 cases of burned children were studied, including analysis of correlations of the stages and outcome of the disease (varicela), the trauma (burns) and the graft (repair surgery). As a result, the authors emphasize the following findings: 1. Burns and their repair are not aggravating factors for varicella. In a small number of cases the exanthema looked more confluent in the graft surgical areas and in the first degree burns healing spontaneously. 2. Usually there was an uneventful outcome of graft repair surgery on a varicella patient, either during the incubation period, the acme or the convalescence. 3. The fact that the outmost intensity of secondary viremia of varicella occurs before the onset of exanthemia, that is, during the late incubation period, is confirmed.

    An important component of the multicentre Chronic Effects of Neurotrauma Consortium (CENC) project is the development of improved quantitative magnetic resonance imaging (MRI) methods, including volumetric analysis. Although many studies routinely employ quality assurance (QA) procedures including MR and human phantoms to promote accuracy and monitor site differences, few studies perform rigorous direct comparisons of these data nor report findings that enable inference regarding site-to-site comparability. These gaps in evaluating cross-site differences are concerning, especially given the well-established differences that can occur between data acquired on scanners with different manufacturer, hardware or software. This study reports findings on (1) a series of studies utilizing two MR phantoms to interrogate machine-based variability using data collected on the same magnet, (2) a human phantom repeatedly imaged on the same scanner to investigate within-subject, within-site variability and (3) a human phantom imaged on three different scanners to examine within subject, between-site variability. Although variability is relatively minimal for the phantom scanned on the same magnet, significantly more variability is introduced in a human subject, particularly when regions are relatively small or multiple sites used. Vigilance when combining data from different sites is suggested and that future efforts address these issues.

    This paper describes RI cisternographic (RIC) examinations of whiplash-associated disorder (WAD) and results of their treatment with nerve block and epidural blood patch (EBP) conducted in authors' facilities. Subjects were 40 chronic (av. symptomatic period of 3.1 y) WAD patients (av. age 34 y) with traffic (28 cases), sports (7) and falling (5) causes with complication of suspicious cerebrospinal fluid (CSF) leak. RIC was done 2.5-24 hr after injection of 37 MBq of 111 In-diethylenetriamine pentaacetic acid (DTPA) in the medullary space through epidural puncturing needle. Positive finding of clear leak or early accumulation of RI in the bladder was seen in 21 cases and negative, in 19. Positive patients had significantly higher rates of headache, abnormal vision and fatigue than negative ones. EBP was conducted through X-ray to all positive patients and to negative ones with strongly suspicious leak complication (7 cases), which resulted in improvement of symptoms like headache and vision in the former, but no improvement in the latter cases. Repeated RIC of the patients with poor improvement in the former was suggested effective for judgment of repetition of EBP treatment. Cervical facet joint blocks were found effective in cases with posterior cervical pain. Symptoms in WAD accompanying headache should be differentially diagnosed whether it is derived from posttraumatic CSF leak or from pain due to cervical facet arthritis. (R.T.)

    Following a major burn, skeletal muscle protein synthesis rate increases but is often insufficient to compensate for massively elevated muscle protein breakdown rates. Given the long-term nature of the pathophysiologic response to burn injury, we hypothesized that muscle protein synthesis rate would be chronically elevated in severely burned children. The objectives of this study were to characterize muscle protein synthesis rate of burned children over a period of 24 months after injury and to identify predictors that influence this response. A total of 87 children with 40% or greater total body surface area (TBSA) burned were included. Patients participated in stable isotope infusion studies at 1, 2, and approximately 4 weeks after burn and at 6, 12, and 24 months after injury to determine skeletal muscle protein fractional synthesis rate. Generalized estimating equations with log link normal distribution were applied to account for clustering of patients and control for patient characteristics. Patients (8 ± 6 years) had large (62, 51-72% TBSA) and deep (47% ± 21% TBSA third degree) burns. Muscle protein fractional synthesis rate was elevated throughout the first 12 months after burn compared with established values from healthy young adults. Muscle protein fractional synthesis rate was lower in boys, in children older than 3 years, and when burns were greater than 80% TBSA. Muscle protein synthesis is elevated for at least 1 year after injury, suggesting that greater muscle protein turnover is a component of the long-term pathophysiologic response to burn trauma. Muscle protein synthesis is highly affected by sex, age, and burn size in severely burned children. These findings may explain the divergence in net protein balance and lean body mass in different populations of burn patients. Prognostic study, level III.

    Many individuals are affected on their higher brain functions, such as intelligence, memory, and attention, even after minor traumatic brain injury (MTBI). Although higher brain dysfunction is based on impairment of the cerebral circulation and metabolism, the precise relationship between them remains unknown. This study was undertaken to investigate the relationship between the cerebral circulation or cerebral metabolism and higher brain dysfunction. Twenty subjects with higher brain dysfunction caused by chronic MTBI were studied. They had no abnormal MRI findings. The full-scale intelligence quotient (FIQ) were quantitatively evaluated by the Wechsler Adult Intelligence Scale-Revised (WAIS-R), and the subjects were classified into the normal group and the impaired group. Concurrent with the evaluation of FIQ, positron emission tomography (PET) was performed by the steady state method with {sup 15}O gases inhalation. Regional cerebral blood flow (rCBF), oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO{sub 2}) were calculated in the bilateral frontal, parietal, temporal, and occipital lobe. First, of all twenty subjects, we investigated rCBF, OEF and CMRO{sub 2} in all regions. Then we compared rCBF, OEF, and CMRO{sub 2} between the normal group and the impaired group based on FIQ score. We also studied the change of FIQ score of 13 subjects 9.3 months after the first evaluation. In addition, we investigated the change of rCBF, OEF and CMRO{sub 2} along with the improvement of FIQ score. Although rCBF and OEF of all subjects were within the normal range in all regions, CMRO{sub 2} of more than half of subjects was under the lower normal limit in all regions except in the right occipital lobe, showing the presence of ''relative luxury perfusion''. Comparison of rCBF, OEF and CMRO{sub 2} between normal group and impaired group revealed that CMRO{sub 2} of the impaired group was significantly lower than that of the

    This study investigates the prevalence of different types of childhood adversities (CA) and posttraumatic stress disorder (PTSD) in female patients with Fibromyalgia or Chronic Widespread Pain (FM/CWP) compared to patients with Functional Dyspepsia (FD) and achalasia. In FM/CWP, we also investigated the association between CA and PTSD on the one hand and pain severity on the other. Patient samples consisted of 154 female FM/CWP, 83 female FD and 53 female achalasia patients consecutively recruited from a tertiary care hospital. Well-validated self-report questionnaires were used to investigate CA and PTSD. Forty-nine per cent of FM/CWP patients reported at least 1 type of CA, compared to 39.7% of FD patients and 23.4% of achalasia patients (p PTSD than both FD (p PTSD comorbidity, but not CA, was associated with self-reported pain severity and PTSD severity mediated the relationship between CA and pain severity. In summary, the prevalence of CA is higher in FM/CWP compared to achalasia, but similar to FD. However, PTSD is more prevalent in FM/CWP compared to FD and associated with higher pain intensity in FM/CWP. As expected and has been shown in other functional disorders, we found elevated levels of childhood adversity in FM/CWP patients. Results of this study however suggest that the impact of childhood adversity (i.e. whether such events have led to the development of PTSD symptoms), rather than the mere presence of such adversity, is of crucial importance in FM/CWP patients. Screening for PTSD symptoms should be an essential part of the assessment process in patients suffering from FM/CWP, and both prevention and intervention efforts should take into account PTSD symptoms and their impact on pain severity and general functioning. © 2017 European Pain Federation - EFIC®.

    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

    Burns are a challenge for trauma care and a contribution to the surgical burden. The former Soviet republic of Ukraine has a foundation for burn care; however data concerning burns in Ukraine has historically been scant. The objective of this paper was to compare a new burn database to identify problems and implement improvements in burn care and prevention in this country. Retrospective analyses of demographic and clinical data of burn patients including Tukey's post hoc test, analysis of variance, and chi square analyses, and Fisher's exact test were used. Data were compared to the American Burn Association (ABA) burn repository. This study included 1752 thermally injured patients treated in 20 hospitals including Specialized Burn Unit in Municipal Hospital #8 Lviv, Lviv province in Ukraine. Scald burns were the primary etiology of burns injuries (70%) and burns were more common among children less than five years of age (34%). Length of stay, mechanical ventilation use, infection rates, and morbidity increased with greater burn size. Mortality was significantly related to burn size, inhalation injury, age, and length of stay. Wound infections were associated with burn size and older age. Compared to ABA data, Ukrainian patients had double the length of stay and a higher rate of wound infections (16% vs. 2.4%). We created one of the first burn databases from a region of the former Soviet Union in an effort to bring attention to burn injury and improve burn care. Copyright © 2013 Elsevier Ltd and ISBI.

    Since the introduction of applications (apps) for smartphones, the popularity of medical apps has been rising. The aim of this review was to demonstrate the current availability of apps related to burns on Google's Android and Apple's iOS store as well as to include a review of their developers, features, and costs. A systematic online review of Google Play Store and Apple's App Store was performed by using the following search terms: "burn," "burns," "thermal," and the German word "Verbrennung." All apps that were programmed for use as medical apps for burns were included. The review was performed from 25 February until 1 March 2014. A closer look at the free and paid calculation apps including a standardized patient was performed. Four types of apps were identified: calculators, information apps, book/journal apps, and games. In Google Play Store, 31 apps were related to burns, of which 20 were calculation apps (eight for estimating the total body surface area (TBSA) and nine for total fluid requirement (TFR)). In Apple's App Store, under the category of medicine, 39 apps were related to burns, of which 21 were calculation apps (19 for estimating the TBSA and 17 for calculating the TFR). In 19 out of 32 available calculation apps, our study showed a correlation of the calculated TFR compared to our standardized patient. The review demonstrated that many apps for medical burns are available in both common app stores. Even free available calculation apps may provide a more objective and reproducible procedure compared to manual/subjective estimations, although there is still a lack of data security especially in personal data entered in calculation apps. Further clinical studies including smartphone apps for burns should be performed. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

    Ball lightning is a rare physical phenomenon, which is not yet completely explained. It is similar to lightning but with different, peculiar characteristics. It can be considered a mix of fire and electricity, concentrated in a fireball with a diameter of 20-cm that most commonly appears suddenly, even in indoor conditions, during a thunderstorm. It moves quickly for several meters, can change direction, and ultimately disappears. During a great storm, a 28-year-old man and his 5-year-old daughter sustained burn wounds after ball lightning came from the outdoors through a chimney. These two patients demonstrated signs of fire and electrical injuries. The father, who lost consciousness, sustained superficial second-degree burn wounds bilaterally on the zygomatic area and deep second-degree burn wounds on his right hand (total body surface area, 4%). His daughter demonstrated superficial second-degree burn wounds on the left part of the face and deep second-degree and third-degree burn wounds (total body surface area, 30%) on the left neck, both upper arms, and the back. In this article, the authors report the first two cases of burn injuries resulting from ball lightning contact indoors. The literature on this rare phenomenon is reviewed to elucidate the nature of ball lightning. Emphasis is placed on the nature of injuries after ball lightning contact, the therapy used, and the long-term complications.

    Hand burns are common in the pediatric population. Optimal hand function is a crucial component of a high-quality survival after burn injury. This can only be achieved with a coordinated approach to the injuries. The aim of this study was to review the management algorithm and outcomes of pediatric hand burns at our institution. In total, 70 children fulfilling our study criteria were treated for a burn hand injury in our Burn Care Center between January 2008 and May 2013. 14 of the 70 pediatric patients underwent surgery because of the depth of the hand burns. The management algorithm depending on the depth of the burn is described. Two patients underwent correction surgery due to burn contractures later. For a successful outcome of the burned hand, the interdisciplinary involvement and cooperation of the plastic and pediatric surgeon, hand therapist, burn team, patient and their parents are crucial.

    Full Text Available Unexpected extreme sudden traumatic stressor may cause post-traumatic stress disorder (PTSD. Important traumatic events include war, violent personal assault (e.g., sexual assault, and physical attack, being taken hostage or kidnapped, confinement as a prisoner of war, torture, terrorist attack, severe car accidents, and natural disasters. In childhood age sexual abuse or witnessing serious injuries or unexpected death of a beloved one are among important traumatic events. PTSD can be categorized into two types of acute and chronic PTSD: if symptoms persist for less than three months, it is termed “acute PTSD,” otherwise, it is called “chronic PTSD.” 60.7% of men and 51.2% of women would experience at least one potentially traumatic event in their lifetime. The lifetime prevalence of PTSD is significantly higher in women than men. Lifetime prevalence of PTSD varies from 0.3% in China to 6.1% in New Zealand. The prevalence of PTSD in crime victims are between 19% and 75%; rates as high as 80% have been reported following rape. The prevalence of PTSD among direct victims of disasters was reported to be 30%–40%; the rate in rescue workers was 10%–20%. The prevalence of PTSD among police, fire, and emergency service workers ranged from 6%–32%. An overall prevalence rate of 4% for the general population, the rate in rescue/recovery occupations ranged from 5% to 32%, with the highest rate reported in search and rescue personnel (25%, firefighters (21%, and workers with no prior training for facing disaster. War is one of the most intense stressors known to man. Armed forces have a higher prevalence of depression, anxiety disorders, alcohol abuse and PTSD. High-risk children who have been abused or experienced natural disasters may have an even higher prevalence of PTSD than adults.

    Full Text Available Traumatic events do not only affect the person who was directly exposed to the incident, but they might also lead to some reactions on people with whom they interact. It is argued that, reactions given to a traumatic event by being exposed to the incident either primarily or secondarily, resemble each other. While in primary exposure the perceived threat is subjective, in secondary exposure the threat belongs to the person one interacts with. Secondary exposition to trauma may lead to re-experiencing, avoidance, and increased arousal symptoms as well as impairment in daily functioning. Briefly, secondary exposition to a traumatic incident induces parallel reactions as in those who are primarily exposed. In addition to these, taking specific precautions help decreasing the negative effects of secondary traumatic stress. This review focuses on the secondary traumatic stress and secondary traumatic stress disorder of workers who offer service in relief operations. For this aim, related theoretical concepts along with the literature studies are presented and information regarding ways of coping with the negative effects of secondary traumatization is discussed.

    This study analyses staphylococcal septicaemia in a series of 1516 burn patients who were admitted to the burn unit of the Al-Babtain Centre for Burns and Plastic Surgery, Ibn Sina Hospital, Kuwait over a period of 6.5 years (1 June 1992-31 December 1998). One hundred and nine patients (7.2%) developed clinically and microbiologically proven septicaemia, of which 80 (73.4%) showed one or the other type of Staphylococcus in their blood. Fifty (62.5%) of them were males and 30 (37.5%) females, with a mean age of 26 years and the mean total body surface area of burns (TBSA) of 45% (range 1-93%). Preschool age children comprised 27.5% of the patients. Flame was the dominant (80%) cause of burn. Of the 80 patients who had 91 episodes of septicaemia, 52 (65%) had MRSA, 8 (10%) MSSA, 11 (13.8%) MRSE and 5 (6.2%) MSSE and 4 (5%) others had mixed organisms. Only the patients with MRSA had multiple episodes. Eight patients (10%) showed septicaemic episodes within only 48 h of admission; however, the majority of the patients (77.5%) had a septicaemic attack within 2 weeks postburn. Of the 52 MRSA septicaemic cases, 39 (75%) survived and 13 (25%) died. Four patients with septicaemia due to mixed infections died. A total of 19 patients were intubated, 14 due to inhalation injury and 5 because of septicaemia; all in the former group died. Glycopeptide therapy (vancomycin/teicoplanin) was instituted immediately following the detection of staphylococci in the blood. No significant difference was noted in relation to mortality amongst the septicaemic patients, whether or not on prophylactic antibiotic. Fifty-six (70%) of the 80 patients had 139 sessions of skin grafting and survived. Of the 52 MRSA patients, 40 had 101 sessions of skin grafting and 33 of them survived. The apparent low mortality was probably due to early detection of the organism, appropriate antibiotic therapy, care for nutrition and early wound cover. This study indicates a high incidence of staphylococcal

    The resuscitation of severe burn remains a controversial area within the burn care profession. There is ongoing debate as to what percentage burn is associated with a sufficient quality of life to support initial resuscitation efforts. We conducted a survey of delegates at the 39th Annual Meeting of the British Burns Association (2005), regarding attitudes towards resuscitation following major burns. Respondents were asked the maximum percentage total body surface area (TBSA) burn beyond which they would not wish to be resuscitated. They were also asked what maximum TBSA they perceived to be commensurate with an acceptable quality of life (QOL). One hundred and forty three of 300 delegates responded to the questionnaire. Thirty three percent of respondents would not wish to be resuscitated with 50-75% TBSA burns or greater. A further 35% would not wish to have life-sustaining intervention with 75-95% TBSA burns or greater. The remaining 32% indicated that they would not want resuscitation with TBSA burns>95%. Regardless of TBSA affected, 16% would not wish resuscitation if they had full thickness facial burns, a further 10% did not want resuscitation if both their hands and faces were affected. Our survey demonstrates the diversity of personal preference amongst burn care professionals. This would suggest that a unifying philosophy regarding the resuscitation of extensive burns will remain elusive.

    The traumatic aortic valvular insufficiency (TAVI), through less frequent after a non-penetrating thoracic traumatism, is a serious entity with a very reserved prognosis. So it must be suspected in every patients with signs or symptoms of de novo heart failure post-traumatism. The transthoracic echocardiography and eventually transesophageal echocardiography have a fundamental role in the confirmation of the diagnosis. The clinical picture of traumatic aortic regurgitation is quickly evolutionary and the non efficacy of medical therapy has placed the valvular substitution surgery as the best succeeded treatment. With the advent of the aortic valve repairing surgery some TAVI cases has been submitted to this procedure. Nevertheless, the development of residual aortic regurgitation in these situations, usually requiring later valvular replacement surgery, make the aortic valvuloplasty a controversial surgical technique. The AA describe a recent clinical case of aortic regurgitation after a non-penetrant thoracic traumatism, discussing the aspects connected with physiopathology, diagnosis and therapy. The singularity of this case was based on the fact that the initial clinical diagnosis had been prejudiced by the context of a polytraumatism and there had been a time free of symptoms between the traumatism and the beginning of the symptomatology of left ventricular failure. Even though the identification of the problem allowed an intensive treatment of this serious situation that ended with the replacement of the aortic valve by mechanical aortic prosthesis, with the patient's total recovery.

    The ecological effects of forest fires burning with high severity are long-lived and have the greatest impact on vegetation successional trajectories, as compared to low-to-moderate severity fires. The primary drivers of high severity fire are unclear, but it has been hypothesized that wind-driven, large fire-growth days play a significant role, particularly on large fires in forested ecosystems. Here, we examined the relative proportion of classified burn severity for individual daily areas burned that occurred during 42 large forest fires in central Idaho and western Montana from 2005 to 2007 and 2011. Using infrared perimeter data for wildfires with five or more consecutive days of mapped perimeters, we delineated 2697 individual daily areas burned from which we calculated the proportions of each of three burn severity classes (high, moderate, and low) using the differenced normalized burn ratio as mapped for large fires by the Monitoring Trends in Burn Severity project. We found that the proportion of high burn severity was weakly correlated (Kendall τ = 0.299) with size of daily area burned (DAB). Burn severity was highly variable, even for the largest (95th percentile) in DAB, suggesting that other variables than fire extent influence the ecological effects of fires. We suggest that these results do not support the prioritization of large runs during fire rehabilitation efforts, since the underlying assumption in this prioritization is a positive relationship between severity and area burned in a day.

The mechanism and treatment of these types of injuries are also described. A 44 year-old female was admitted under the care of the burns team following burns secondary to an exploding air-freshener canister. The patient sustained burns to the face, thorax and arms resulting in a seven-day hospital admission. The burns were treated conservatively. To our knowledge this is one of the few documented cases of burns as a result of air-fresheners. As they become more ubiquitous, we anticipate the incidence of such cases to increase. As such, they pose a potential public health concern on a massive scale.

    To substantiate the use of nanostructured bioplastic material for the treatment of traumatic eye injuries. The study enrolled 96 eyes of 48 rabbits and was carried out in 3 series of experiments, different in the type of induced corneal trauma: mechanical erosion, alkaline or acid burn. The animals were clinically monitored and sacrificed for morphological investigation at days 3, 7, 14, 30, and 90. The size of mechanical corneal erosions was repeatedly evaluated with fluorescein eye stain test. In the experimental group, Hyamatrix biomaterial was topically administered according to an original technique. In the controls, soft contact lenses were inserted and sutured. Complete closure of the epithelial defect with no impact on corneal properties was achieved in 3 days in the experimental group and in4 days in the control group. As for alkaline and acid corneal burns, experimental and control groups received Hyamatrix biomaterial and Solcoseryl eye gel correspondingly. In the experimental group of alkaline burn the defect closed by day 7, in the controls--by day 10-11. Acid-induced corneal edema also resolved by day 7 in the experimental group and by day 14 in the control group. 1. The results of this experimental and morphological study prove the hyaluronic acid-derived nanostructured bioplastic material effective in accelerating corneal re-epithelialization after mechanical erosions as compared with the controls. 2. Topical application of the hyaluronic acid-derived nanostructured bioplastic material shortens the exudative phase of inflammation, promotes corneal defect closure with formation of a more subtle opacification, and stimulates corneal restoration after chemical burns.

    Full Text Available Abstract 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.

    Summary Tattoos are on the rise, and so are patients with tattooed burn lesions. A proper assessment with regard to burn depth is often impeded by the tattoo dye. Laser speckle contrast analysis (LASCA) is a technique that evaluates burn lesions via relative perfusion analysis. We assessed the effect of tattoo skin pigmentation on LASCA perfusion imaging in a multicolour tattooed patient. Depth of burn lesions in multi-coloured tattooed and untattooed skin was assessed using LASCA. Relative perfusion was measured in perfusion units (PU) and compared to various pigment colours, then correlated with the clinical evaluation of the lesion. Superficial partial thickness burn (SPTB) lesions showed significantly elevated perfusion units (PU) compared to normal skin; deep partial thickness burns showed decreased PU levels. PU of various tattoo pigments to normal skin showed either significantly lower values (blue, red, pink) or significantly increased values (black) whereas orange and yellow pigment showed values comparable to normal skin. In SPTB, black and blue pigment showed reduced perfusion; yellow pigment was similar to normal SPTB burn. Deep partial thickness burn (DPTB) lesions in tattoos did not show significant differences to normal DPTB lesions for black, green and red. Tattoo pigments alter the results of perfusion patterns assessed with LASCA both in normal and burned skin. Yellow pigments do not seem to interfere with LASCA assessment. However proper determination of burn depth both in SPTB and DPTB by LASCA is limited by the heterogenic alterations of the various pigment colours. PMID:28149254

    The Burning Mouth Syndrome (BMS) is an oral mucosa pain--with or without inflammatory signs--without any specific lesion. It is mostly observed in women aged 40-60 years. This pain feels like a moderate/severe burning, and it occurs more frequently on the tongue, but it may also be felt at the gingiva, lips and jugal mucosa. It may worsen during the day, during stress and fatigue, when the patient speaks too much, or through eating of spicy/hot foods. The burning can be diminished with cold food, work and leisure. The goal of this review article is to consider possible BMS etiologies and join them in 4 groups to be better studied: local, systemic, emotional and idiopathic causes of pain. Knowing the different diagnoses of this syndrome, we can establish a protocol to manage these patients. Within the local pain group, we must investigate dental, allergic and infectious causes. Concerning systemic causes we need to look for connective tissue diseases, endocrine disorders, neurological diseases, nutritional deficits and salivary glands alterations that result in xerostomia. BMS etiology may be of difficult diagnosis, many times showing more than one cause for oral pain. A detailed interview, general physical examination, oral cavity and oropharynx inspection, and lab exams are essential to avoid a try and error treatment for these patients.

    Post-traumatic acute renal failure requiring renal replacement therapy in an intensive care unit (ICU) is associated with high mortality. To assess indicators of improved survival. This was a retrospective cohort study of 64 consecutive trauma patients (penetrating and blunt trauma and burns) who underwent haemodialysis (HD) over a period of 5 years. Information on pre-hospital and in-hospital resuscitation, trauma scores and physiological scores and daily ICU records were collected. The majority of the patients were dialysed with continuous venovenous haemofiltration in the early years of the study and later with sustained low-efficiency dialysis. Of the 64 patients 47 died, giving an overall mortality rate of 73%. Mortality was highest in the burns patients (84%). Survival in all patients, irrespective of injury, was unrelated to the Revised Trauma Score, Injury Severity Score, Acute Physiology and Chronic Health Evaluation Score or Trauma Injury Severity Score. The duration of HD did not differ significantly between the three trauma groups, and age was not a significant predictor of survival. Patients who were polyuric at the time of the initiation of HD had a lower mortality rate than those who were oliguric, anuric or normouric, although this did not reach statistical significance (p=0.09). Acute renal failure in trauma patients is associated with a low survival rate. Controversial conclusions have been presented in the literature. In this study, none of the parameters previously reported to affect survival proved to be valid, although the number of patients was comparable with those in other studies. Since understanding of the predictors and course of renal failure in trauma patients is still at an early stage, there is a need for multicentre prospective studies.

  17. Traumatic cervical artery dissection.

    2005-01-01

    Traumatic cervical artery dissection (TCAD) is a complication of severe blunt head or neck trauma, the main cause being motor vehicle accidents. TCAD are increasingly recognized, and incidences of up to 0.86% for internal carotid and 0.53% for traumatic vertebral artery dissections (TVAD) among blunt trauma victims are reported. Diagnostic evaluation for TCAD is mandatory in the presence of (1) hemorrhage of potential arterial origin originating from the nose, ears, mouth, or a wound; (2) expanding cervical hematoma; (3) cervical bruit in a patient >50 years of age; (4) evidence of acute infarct at brain imaging; (5) unexplained central or lateralizing neurological deficit or transient ischemic attack, or (6) Horner syndrome, neck or head pain. In addition, a number of centers screen asymptomatic patients with blunt trauma for TCAD. Catheter angiography is the standard of reference for diagnosis of TCAD. Color duplex ultrasound, computed tomographic, and magnetic resonance angiography are noninvasive screening alternatives, but each method has its diagnostic limitations compared to catheter angiography. Anticoagulants and antiplatelet drugs may prevent ischemic stroke, but bleeding from traumatized tissues may offset the benefits of antithrombotic treatment. Endovascular therapy of dissected vessels, thrombarterectomy, direct suture of intimal tears, and extracranial-intracranial bypass should be considered in exceptional cases. Neurological outcome is probably worse in TCAD compared to spontaneous CAD, although it is unclear whether this is due to dissection-induced ischemic stroke or associated traumatic lesions.

    psoralen and ultraviolet A (PUVA) phototherapy (PT) has become a standard treatment for several severe skin diseases. Photosensitization is done by oral psoralen intake. In minor cases, PUVA can lead to skin changes like erythema and hyperpigmentation. However, it can also lead to severe burn injuries when exposed to extensive UV light. This makes the treatment in a burn center inevitable. We report the clinical observation of a 38-year-old man presenting with an extensive burn injury caused by sun tanning after PUVA PT. There are just few cases of extensive burns induced by PUVA PT. Prevention becomes manifest in patient information, correct calculation of dosage, evaluation of photosensitivity, and close observation. In cases of severe burn injuries, patients should be referred to a burn center for optimal conservative treatment. Surgical intervention is usually not necessary.

    2018-05-01

    Although the overall incidence of and mortality rate associated with burn injury have decreased in recent decades, burns remain a significant source of morbidity and mortality in children. Children with major burns require emergent resuscitation. Resuscitation is similar to that for adults, including pain control, airway management, and administration of intravenous fluid. However, in pediatrics, fluid resuscitation is needed for burns greater than or equal to 15% of total body surface area (TBSA) compared with burns greater than or equal to 20% TBSA for adults. Unique to pediatrics is the additional assessment for non-accidental injury and accurate calculation of the percentage of total burned surface area (TBSA) in children with changing body proportions are crucial to determine resuscitation parameters, prognosis, and disposition.

    Post-traumatic headache is one of the most common symptoms occurring after mild traumatic brain injury in children. This is an expert opinion-based two-part review on pediatric post-traumatic headaches. In part II, we focus on the medical management of post-traumatic headaches. There are no randomized controlled trials evaluating the efficacy of therapies specifically for pediatric post-traumatic headaches. Thus, the algorithm we propose has been extrapolated from the primary headache literature and small noncontrolled trials of post-traumatic headache. Most post-traumatic headaches are migraine or tension type, and standard medications for these headache types are used. A multifaceted approach is needed to address all the possible causes of headache and any comorbid conditions that may delay recovery or alter treatment choices. For acute treatment, nonsteroidal anti-inflammatories can be used. If the headaches have migrainous features and nonsteroidal anti-inflammatories are not effective, triptans may be beneficial. Opioids are not indicated. Medication overuse should be avoided. For preventive treatments, some reports indicate that amitriptyline, gabapentin, or topiramate may be beneficial. Amitriptyline is a good choice because it can be used to treat both migraine and tension-type headaches. Nerve blocks, nutraceuticals (e.g. melatonin), and behavioral therapies may also be useful, and lifestyle factors, especially adequate sleep hygiene and strategies to cope with anxiety, should be emphasized. Improved treatment of acute post-traumatic headache may reduce the likelihood of developing chronic headaches, which can be especially problematic to effectively manage and can be functionally debilitating.

    Burn wounds cause high levels of morbidity and mortality worldwide. People with burns are particularly vulnerable to infections; over 75% of all burn deaths (after initial resuscitation) result from infection. Antiseptics are topical agents that act to prevent growth of micro-organisms. A wide range are used with the intention of preventing infection and promoting healing of burn wounds. To assess the effects and safety of antiseptics for the treatment of burns in any care setting. In September 2016 we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid MEDLINE (In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL. We also searched three clinical trials registries and references of included studies and relevant systematic reviews. There were no restrictions based on language, date of publication or study setting. We included randomised controlled trials (RCTs) that enrolled people with any burn wound and assessed the use of a topical treatment with antiseptic properties. Two review authors independently performed study selection, risk of bias assessment and data extraction. We included 56 RCTs with 5807 randomised participants. Almost all trials had poorly reported methodology, meaning that it is unclear whether they were at high risk of bias. In many cases the primary review outcomes, wound healing and infection, were not reported, or were reported incompletely.Most trials enrolled people with recent burns, described as second-degree and less than 40% of total body surface area; most participants were adults. Antiseptic agents assessed were: silver-based, honey, Aloe Vera, iodine-based, chlorhexidine or polyhexanide (biguanides), sodium hypochlorite, merbromin, ethacridine lactate, cerium nitrate and Arnebia euchroma. Most studies compared antiseptic with a topical antibiotic, primarily silver sulfadiazine (SSD); others compared antiseptic with a non

  2. Marginally Stable Nuclear Burning

    Thermonuclear X-ray bursts result from unstable nuclear burning of the material accreted on neutron stars in some low mass X-ray binaries (LMXBs). Theory predicts that close to the boundary of stability oscillatory burning can occur. This marginally stable regime has so far been identified in only a small number of sources. We present Rossi X-ray Timing Explorer (RXTE) observations of the bursting, high- inclination LMXB 4U 1323-619 that reveal for the first time in this source the signature of marginally stable burning. The source was observed during two successive RXTE orbits for approximately 5 ksec beginning at 10:14:01 UTC on March 28, 2011. Significant mHz quasi- periodic oscillations (QPO) at a frequency of 8.1 mHz are detected for approximately 1600 s from the beginning of the observation until the occurrence of a thermonuclear X-ray burst at 10:42:22 UTC. The mHz oscillations are not detected following the X-ray burst. The average fractional rms amplitude of the mHz QPOs is 6.4% (3 - 20 keV), and the amplitude increases to about 8% below 10 keV.This phenomenology is strikingly similar to that seen in the LMXB 4U 1636-53. Indeed, the frequency of the mHz QPOs in 4U 1323-619 prior to the X-ray burst is very similar to the transition frequency between mHz QPO and bursts found in 4U 1636-53 by Altamirano et al. (2008). These results strongly suggest that the observed QPOs in 4U 1323-619 are, like those in 4U 1636-53, due to marginally stable nuclear burning. We also explore the dependence of the energy spectrum on the oscillation phase, and we place the present observations within the context of the spectral evolution of the accretion-powered flux from the source.

    Fatigue is a common consequence of numerous pediatric health conditions. In adult burn survivors, fatigue was found to be a major problem. The current cross-sectional study is aimed at determining the levels of perceived fatigue in pediatric burn survivors. Perceived fatigue was assessed in 23 children and adolescents (15 boys and 8 girls, aged 6-18 years, with burns covering 10-46% of the total body surface area, 1-5 years post burn) using both child self- and parent proxy reports of the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale. Outcomes were compared with reference values of non-burned peers. At group level, pediatric burn survivors did not report significantly more symptoms of fatigue than their non-burned peers. Individual assessments showed, however, that four children experienced substantial symptoms of fatigue according to the child self-reports, compared to ten children according to the parent proxy reports. Furthermore, parents reported significantly more symptoms of fatigue than the children themselves. Age, gender, extent of burn, length of hospital stay, and number of surgeries could not predict the level of perceived fatigue post-burn. Our results suggest that fatigue is prevalent in at least part of the pediatric burn population after 1-5 years. However, the fact that parents reported significantly more symptoms of fatigue then the children themselves, hampers evident conclusions. It is essential for clinicians and therapists to consider both perspectives when evaluating pediatric fatigue after burn and to determine who needs special attention, the pediatric burn patient or its parent.

    Historical relationships between weather, the Canadian fire weather index (FWI) system components and area burned in Canadian ecozones were analysed on a monthly basis in tandem with output from the Canadian and the Hadley Centre GCMs to project future area burned. Temperature and fuel moisture were the variables best related to historical monthly area burned with 36-64% of the variance explained depending on ecozone. Our results suggest significant increases in future area burned although there are large regional variations in fire activity. This was especially true for the Canadian GCM where some ecozones show little change in area burned, however area burned was not projected to decrease in any of the ecozones modelled. On average, area burned in Canada is projected to increase by 74-118% by the end of this century in a 3 x CO2 scenario. These estimates do not explicitly take into account any changes in vegetation, ignitions, fire season length, and human activity (fire management and land use activities) that may influence area burned. However, the estimated increases in area burned would have significant ecological, economic and social impacts for Canada

    2012-09-30

    Burning mouth syndrome (BMS) refers to chronic orofacial pain, unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women. BMS is characterized by an intense burning or stinging sensation, typically on the tongue or in other areas of the oral mucosa. It can be accompanied by other sensory disorders such as dry mouth or taste alterations. Probably of multifactorial origin, and often idiopathic, with a still unknown etiopathogenesis in which local, systemic and psychological factors are implicated. Currently there is no consensus on the diagnosis and classification of BMS. This study reviews the literature on this syndrome, with special reference to the etiological factors that may be involved and the clinical aspects they present. The diagnostic criteria that should be followed and the therapeutic management are discussed with reference to the most recent studies.

    Accurate diagnosis and localization of peripheral nerve traumatic injury remains difficult. Early diagnosis and repair of nerve discontinuity lesions lead to better outcome than delayed repair. We used new high frequency ultrasound to evaluate 24 patients with 29 traumatic nerve injuries. There were a variety of causes including gunshot wounds, blunt injuries, burns, stabbings, and motor vehicle accidents. The patients were then either treated surgically with nerve status directly observed or followed clinically for recovery of nerve function. The ultrasound findings correspond with the clinical outcome of 28 of the 29 nerves. While this is a study limited by a small patient number, ultrasound evaluation should be considered in the evaluation of nerve injury and can lead to early diagnosis and treatment of surgical nerve injuries.

    Although nearly 11 million individuals yearly require medical treatment due to burn injuries and develop clinically intractable pain, burn injury-induced pain is poorly understood, with relatively few studies in preclinical models. To elucidate mechanisms of burn injury-induced chronic pain, we utilized a second-degree burn model, which produces a persistent neuropathic pain phenotype. Rats with burn injury exhibited reduced mechanical pain thresholds ipsilateral to the burn injury. Ipsilateral WDR neurons in the spinal cord dorsal horn exhibited hyperexcitability in response to a range of stimuli applied to their hindpaw receptive fields. Because dendritic spine morphology is strongly associated with synaptic function and transmission, we profiled dendritic spine shape, density, and distribution of WDR neurons. Dendritic spine dysgenesis was observed on ipsilateral WDR neurons in burn-injured animals exhibiting behavioral and electrophysiological evidence of neuropathic pain. Heat hyperalgesia testing produced variable results, as expected from previous studies of this model of second-degree burn injury in rats. Administration of Rac1-inhibitor, NSC23766, attenuated dendritic spine dysgenesis, decreased mechanical allodynia and electrophysiological signs of burn-induced neuropathic pain. These results support two related implications: that the presence of abnormal dendritic spines contributes to the maintenance of neuropathic pain, and that therapeutic targeting of Rac1 signaling merits further investigation as a novel strategy for pain management after burn injury. © 2013.

    Full Text Available The data presented here are associated with the article “The blister fluid proteome of paediatric burns” (Zang et al., 2016 [1]. Burn injury is a highly traumatic event for children. The degree of burn severity (superficial-, deep-, or full-thickness injury often dictates the extent of later scar formation which may require long term surgical operation or skin grafting. The data were obtained by fractionating paediatric burn blister fluid samples, which were pooled according to burn depth and then analysed using data dependent acquisition LC–MS/MS. The data includes a table of all proteins identified, in which burn depth category they were found, the percentage sequence coverage for each protein and the number of high confidence peptide identifications for each protein. Further Gene Ontology enrichment analysis shows the significantly over-represented biological processes, molecular functions, and cellular components of the burn blister fluid proteome. In addition, tables include the proteins associated with the biological processes of “wound healing” and “response to stress” as examples of highly relevant processes that occur in burn wounds.

    In several biomes, including croplands, wooded savannas, and tropical forests, many small fires occur each year that are well below the detection limit of the current generation of global burned area products derived from moderate resolution surface reflectance imagery. Although these fires often generate thermal anomalies that can be detected by satellites, their contributions to burned area and carbon fluxes have not been systematically quantified across different regions and continents. Here we developed a preliminary method for combining 1-km thermal anomalies (active fires) and 500 m burned area observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) to estimate the influence of these fires. In our approach, we calculated the number of active fires inside and outside of 500 m burn scars derived from reflectance data. We estimated small fire burned area by computing the difference normalized burn ratio (dNBR) for these two sets of active fires and then combining these observations with other information. In a final step, we used the Global Fire Emissions Database version 3 (GFED3) biogeochemical model to estimate the impact of these fires on biomass burning emissions. We found that the spatial distribution of active fires and 500 m burned areas were in close agreement in ecosystems that experience large fires, including savannas across southern Africa and Australia and boreal forests in North America and Eurasia. In other areas, however, we observed many active fires outside of burned area perimeters. Fire radiative power was lower for this class of active fires. Small fires substantially increased burned area in several continental-scale regions, including Equatorial Asia (157%), Central America (143%), and Southeast Asia (90%) during 2001-2010. Globally, accounting for small fires increased total burned area by approximately by 35%, from 345 Mha/yr to 464 Mha/yr. A formal quantification of uncertainties was not possible, but sensitivity

  15. In-situ burning of Orimulsion : small scale burns

    This study examined the feasibility of burning Orimulsion. In-situ burning has always been a viable method for cleaning oil spills on water because it can effectively reduce the amount of spilled oil and eliminate the need to collect, store, transport and dispose of recovered oil. Orimulsion, however, behaves very differently from conventional oil when it is spilled because of its composition of 70 per cent bitumen in 30 per cent water. In-situ burning of this surfactant-stablized oil-in-water emulsion has never been seriously considered because of the perception that Orimulsion could not be ignited, and if it could, ignition would not be sustained. In this study, burn tests were conducted on 3 scales in a Cleveland Open Cup apparatus of 5 cm, 10 cm and 50 cm diameters. Larger scale burns were conducted in specially built pans. All tests were conducted on salt water which caused the bitumen to separate from the water. The objective was to determine if sufficient vapours could be generated to ignite the Orimulsion. The study also measured if a sustained flame would result in successful combustion. Both objectives were successfully accomplished. Diesel fuel was used to ignite the Orimulsion in the specially designed pan for large scale combustion. Quantitative removal of Orimulsion was achieved in all cases, but in some burns it was necessary to re-ignite the Orimulsion. It was noted that when Orimulsion burns, some trapped water droplets in the bitumen explode with enough force to extinguish a small flame. This did not occur on large-scale burns. It was concluded that the potential for successful in-situ burning increases with size. It was determined that approximately 1 mm in thickness of diesel fuel is needed to ignite a burn. 5 refs., 3 tabs., 4 figs

    Each year, thousands of women experience violence, and many of these are survivors of intimate partner violence. Each year, thousands of nurses provide physical and emotional care to these women. Nurses and employers need to recognize that exposures to traumatized women place nurses at risk for the development of secondary traumatic stress disorder. This article describes secondary traumatic stress, its risk factors, and its consequences. Workplace interventions and policies are recommended to reduce the avoidance, numbness, intrusive imagery, and other negative symptoms associated with secondary traumatic stress disorder.

    2011-09-01

    Full Text Available Background: Traumatic ulcer is a common form of ulceration occured in oral cavity caused by mechanical trauma, either acute or chronic, resulting in loss of the entire epithelium. Traumatic ulcer often occurs in children that are usually found on buccal mucosa, labial mucosa of upper and lower lip, lateral tongue, and a variety of areas that may be bitten. To properly diagnose the ulcer, dentists should evaluate the history and clinical description in detail. If the lesion is allegedly accompanied by other infections, such as fungal, bacterial or viral infections, microbiological or serological tests will be required. One of the initial therapy given for fungal infection is nystatin which aimed to support the recovery and repair processes of epithelial tissue in traumatic ulcer case. Purpose: This case report is aimed to emphasize the importance of microbiological examination in suspected cases of ulcer accompanied with traumatic fungal infection. Case: A 12-year-old girl came to the clinic of Pediatric Dentistry, Faculty of Dentistry, University of Indonesia on June 9, 2011 accompanied with her mother. The patient who had a history of geographic tongue came with complaints of injury found in the middle of the tongue. The main diagnosis was ulcer accompanied with traumatic fungal infection based on the results of swab examination. Case management: This traumatic ulcer case was treated with Dental Health Education, oral prophylaxis, as well as prescribing and usage instructions of nystatin. The recovery and repair processes of mucosal epithelium of the tongue then occured after the use of nystatin. Conclusion: It can be concluded that microbiological examination is important to diagnose suspected cases of ulcer accompanied with traumatic fungal infection. The appropriate treatment such as nystatin can be given for traumatic fungal infection.Latar belakang: Ulkus traumatic merupakan bentuk umum dari ulserasi rongga mulut yang terjadi akibat trauma

  5. Traumatic insemination in terrestrial arthropods.

    2014-01-01

    Traumatic insemination is a bizarre form of mating practiced by some invertebrates in which males use hypodermic genitalia to penetrate their partner's body wall during copulation, frequently bypassing the female genital tract and ejaculating into their blood system. The requirements for traumatic insemination to evolve are stringent, yet surprisingly it has arisen multiple times within invertebrates. In terrestrial arthropods traumatic insemination is most prevalent in the true bug infraorder Cimicomorpha, where it has evolved independently at least three times. Traumatic insemination is thought to occur in the Strepsiptera and has recently been recorded in fruit fly and spider lineages. We review the putative selective pressures that may have led to the evolution of traumatic insemination across these lineages, as well as the pressures that continue to drive divergence in male and female reproductive morphology and behavior. Traumatic insemination mechanisms and attributes are compared across independent lineages.

    Full Text Available History of present illness: A 48-year-old male with unknown past medical history presents as a trauma after being hit by a car traveling approximately 25 miles per hour. On initial presentation, the patient is confused, combative, and not answering questions appropriately. The patient is hypotensive with a blood pressure of 68/40 and a heart rate of 50 beats per minute, with oxygen saturation at 96% on room air. FAST scan is positive for fluid in Morrison’s pouch, splenorenal space, and pericardial space. Significant findings: The initial chest x-ray showed an abnormal superior mediastinal contour (blue line, suggestive of a possible aortic injury. The CT angiogram showed extensive circumferential irregularity and outpouching of the distal aortic arch (red arrows compatible with aortic transection. In addition, there was a circumferential intramural hematoma, which extended through the descending aorta to the proximal infrarenal abdominal aorta (green arrow. There was also an extensive surrounding mediastinal hematoma extending around the descending aorta and supraaortic branches (purple arrows. Discussion: Traumatic aortic injury is a life-threatening event. The incidence of blunt thoracic aortic injury is low, between 1 to 2 percent of those patients with blunt thoracic trauma.1 However, approximately 80% of patients with traumatic aortic injury die at the scene.2 Therefore it is imperative to diagnose traumatic aortic injury in a timely fashion. The diagnosis can be difficult due to the non-specific signs and symptoms and other distracting injuries. Clinical suspicion should be based on the mechanism of the injury and the hemodynamic status of the patient. In any patient with blunt or penetrating trauma to the chest that is hemodynamically unstable, traumatic aortic injury should be on the differential. Chest x-ray can be used as a screening tool. A normal chest x-ray has a negative predictive value of approximately 97%. CTA chest is the

    Orbital emphysema can be produced by trans-conjunctival migration of air from a high pressure airgun. In an industrial accident an 8 mm conjunctival laceration was produced in the superior fornix which acted as a portal of entry for air into the subconjunctival, subcutaneous, and retrobulbar spaces. Computed tomography revealed no evidence of orbital fracture and showed that traumatic orbital emphysema occurred without a broken orbital bone.

    Estimation of the total body surface area burned (%TBSA) following a burn injury is used in determining whether to transfer the patient to a burn center and the required fluid resuscitation volumes. Unfortunately, the commonly applied methods of estimation have revealed inaccuracies, which are mostly related to human error. To calculate the %TBSA (quotient), it is necessary to divide the burned surface area (Burned BSA) (numerator in cm2) by the total body surface area (Total BSA) (denominator in cm2). By using everyday objects (eg. credit cards, smartphones) with well-defined surface areas as reference for estimations of Burned BSA on the one hand and established formulas for Total BSA calculation on the other (eg. Mosteller), we propose an approximation method to assess %TBSA more accurately than the established methods. To facilitate distribution, and respective user feedback, we have developed a smartphone app integrating all of the above parameters, available on popular mobile device platforms. This method represents a simple and ready-to-use clinical decision support system which addresses common errors associated with estimations of Burned BSA (=numerator). Following validation and respective user feedback, it could be deployed for testing in future clinical trials. This study has a level of evidence of IV and is a brief report based on clinical observation, which points to further study.

    Mild traumatic brain injury is very common in Western societies, affecting approximately 1.8 million individuals in the USA. Even though between 30% and 90% of patients develop post-traumatic headache, post-traumatic headache remains a very controversial disorder. Particularly when it comes to chronic post-traumatic headache following mild closed head injury and headache attributed to whiplash injury. Some experts are disputing its existence as a genuine disorder. Indistinct disease classification, unresolved pathophysiological mechanism, and the role of accident-related legal issues further fuel this controversy. The complex combination of pain and neuropsychological symptoms needs further research in understanding the underlying pathophysiological mechanisms associated with the acute headache following trauma but more so the mechanisms associated with the development of chronic pain in some patients. Investigators should refrain from oversimplifying these complex mechanisms as hysteric exaggeration of everyday complains and from implying greed as motivation for this potentially very disabling disease.

    This study aimed to elucidate the illness representations of patients with traumatic injury and to examine what extent their illness representations change over time. Traumatic injury has attracted global concern because it is the major reason for death and disability in people under 45 years old. One model, the Common Sense Model of Illness Representation (CSMIR), has the potential to help individuals adjust to changes in health status such as traumatic injury. Longitudinal study design. This study was conducted using a and collected data prior to hospital discharge and at three and six months after hospital discharge. One individual question form and the Chinese Illness Perception Questionnaire Revised (IPQ-R) (Trauma) were used to collect demographic data, clinical data and illness representations. A total of 114 participants completed the survey three times. The overall response rate was 79.7%. Six subscales of the Chinese (Trauma): identity, emotional representations, consequences, controllability, illness coherence and causes of the Chinese IPQ-R (Trauma) changed significantly over time. Two subscales, Timeline (acute/chronic) and Timeline Cyclical, did not change significantly. Based on these findings, there may be a window of opportunity to provide appropriate interventions to individuals with traumatic injury at each time point. The results of this study have implications for nursing practice and further nursing research. Understanding illness representation in patients with traumatic injury may help nurses to provide anticipatory guidance and to design nursing interventions before and after hospital discharge, ultimately to improve health outcomes of those patients.

    2008-07-01

    The leading etiologies of pediatric burns are scald, thermal, and electrical injuries. The initial management of burns involves assessment of burn depth and total body surface area (TBSA) affected, a history, and physical examination. Calculation of percent of TBSA affected is an important determinant of the necessity for hospitalization versus outpatient management. Only second- and third-degree burns are included in the calculation. The criteria for outpatient management vary based on the center experience and resources. One such set of criteria in an experienced burn center includes burn affecting less than 15% TBSA, therefore not requiring fluid resuscitation; the ability to take in oral fluids, excluding serious perioral burns; no airway involvement or aspiration of hot liquid; no abuse; and dependable family able to transport the patient for clinic appointments. Once the child is ready to reenter school, the physician must discuss with the family and school staff any needs and expectations for the child, including wound care. Social reintegration can be difficult. Educating the teachers and staff of the child's appearance may help prepare the students.

  14. Rehabilitation of the burn patient

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Rehabilitation is an essential and integral part of burn treatment. It is not something which takes place following healing of skin grafts or discharge from hospital; instead it is a process that starts from day one of admission and continues for months and sometimes years after the initial event. Burns rehabilitation is not something which is completed by one or two individuals but should be a team approach, incorporating the patient and when appropriate, their family. The term ′Burns Rehabilitation′ incorporates the physical, psychological and social aspects of care and it is common for burn patients to experience difficulties in one or all of these areas following a burn injury. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. The aims of burn rehabilitation are to minimise the adverse effects caused by the injury in terms of maintaining range of movement, minimising contracture development and impact of scarring, maximising functional ability, maximising psychological wellbeing, maximising social integration

    Ahn, Chris S; Maitz, Peter K M

    2012-11-01

    It is difficult to define the true cost of a burns injury, however there has always been a consensus that the costs associated with burns care are high. This study aims to achieve an accurate calculation of the cost of acute burns care in an Australian context. A retrospective review of 20 adult burn patients treated at our Centre was performed. An itemized price list was prepared based on items, services and equipment actually utilized in the care of burns patients. Case records were reviewed for a count of quantities to calculate costs for each item. Regression analysis was performed to produce a cost vs %TBSA curve for cost prediction. A cost breakdown was also performed for analysis of the most significant areas of expenditure and their trends with %TBSA. The cost calculated for an average adult burns patient was AU$71,056 (US$73,532). The total cost of all 20 patients was AU$2,449,112 (US$2,534,464). %TBSA injured was confirmed as the primary determinant of cost. Hospital length of stay, operative costs, dressings and staffing were found to be the most significant components of cost and increased most prominently with %TBSA. Compared to our findings, expenditure for prevention and education programs is minimal. There is limited conclusive evidence that changes in management protocols have had successful impact on the cost of burns treatment. Future progress in burns management may effect factors such as hospital length of stay, however until such changes, resource allocation should recognize the importance of prevention and its success at reduction of injury severity for real reductions in cost of burns care.

    connection correlated with both associative memory and information processing speed and normalized when these functions improved. We have previously shown abnormally high posterior cingulate cortex connectivity in the chronic phase after traumatic brain injury, and this abnormality was also observed in patients with post-traumatic amnesia. Patients with post-traumatic amnesia showed evidence of widespread traumatic axonal injury measured using diffusion magnetic resonance imaging. This change was more marked within the cingulum bundle, the tract connecting the parahippocampal gyrus to the posterior cingulate cortex. These findings provide novel insights into the pathophysiology of post-traumatic amnesia and evidence that memory impairment acutely after traumatic brain injury results from altered parahippocampal functional connectivity, perhaps secondary to the effects of axonal injury on white matter tracts connecting limbic structures involved in memory processing. © The Author (2016).

    2010-07-10

    Burning mouth syndrome is a chronic pathology of unknown ethiopathogenesis. The aim of this study was to evaluate whether acupuncture can produce a reduction of the burning sensation by influencing the oral microcirculation. Thirty patients (10 male and 20 female; mean age +/- SD = 65.4 +/- 2.17) and 30 healthy subjects (10 male and 20 female; mean age +/- SD = 62.06 +/- 6.72) were recruited for the study. The patients were treated with acupunctural techniques based on traditional Chinese medicine. Microcirculation was observed in vivo using videocapillaroscopy at three different times: t(0)) in the absence of acupuncture; t(1)) 1 minute after the insertion of the needles; and t(2)) 5 minutes after the insertion of the needles and following their stimulation. The capillaroscopic observation revealed a significant increase of the capillary tortuousness and density, a reduction of the arborescence and a reduction of burning sensation in such patients. The study shows that acupuncture influences oral microcirculation, resulting in a significant variation of the vascular pattern to which is associated a significant reduction of the burning sensation after three weeks of therapy. Such reduction of the burning sensation has been permanent for the 18 months following the acupuncture therapy. Acupuncture appears a valid therapeutic choice in the management of such patients.

    The affected elbow of 28 patients with traumatic olecranon bursitis was radiographically compared with the homologous elbow of 28 matched controls. Olecranon spurs, amorphous calcium deposits, or both, were present in 16 patients and 4 controls (p<0.01). Air was injected in the bursa in 12 additional patients. Nodules in the bursal floor were noted in 10, and the bursa was partially septated in 8. Olecranon spurs, present in 6 patients, corresponded to the insertion of the triceps tendon. With elbow flexion the bursa flattened and lengthened while the olecranon process glided distally beneath the bursal floor. (Auth.)

    2005-01-01

    Full Text Available The medicinal properties of honey have been recognized since antiquity. Although used as an adjuvant method of accelerating wound healing from ancient times, honey has been sporadically used in the treatment of burns. Honey acts mainly as a hyperosmolar medium and prevents bacterial growth. Because of its high viscosity, it forms a physical barrier, and the presence of enzyme catalase gives honey an antioxidant property. Its high-nutrient content improves substrate supply in local environment promoting epithelialization and angiogenesis. In pediatric burn patients no exclusive study has been conducted using honey as a burn dressing. An attempt is being made to evaluate the effect of honey in the management of burns in pediatric patients.

According to recent studies, up to 25 % of the German working population appear to suffer from what the Amercan physician and psychoanalyst, Herbert Freudenberger, has designated in 1974 as "burn-out syndrome". Characteristic features of this syndrome are emotional exhaustion, depersonalization and low personal accomplishment. People affected by the burn-out syndrome may suffer from depressive or anxious symptoms, from sleep disorders, chronic pain syndromes, or functional disorders of the cardiovascular or gastrointestinal system. Primary causes of the burnout syndrome include high demand combined with low influence, a high level of engagement without sufficient rewards or gratification, and a low level of social support. Preventive measures against burn-out include Balint-like supervision groups. In cases of a fully developed burn-out syndrome, affected persons should undergo either psychotherapy or a multimodal psychosomatic therapy.

    The principal hydrogen burning mechanisms that take place in stars have been elucidated and explored for many decades. However, the introduction of a prodigious flux of electron anti-neutrinos would significantly accelerate these mechanisms and change the path toward the production of an α particle. We discuss the nature of such changes in the hydrogen burning mechanisms, and the side effects spawned from such alterations

  17. DIFFERENTIATING PERIMORTEM AND POSTMORTEM BURNING

    Full Text Available One of the most challenging cases in forensic medicine is ascertaining the cause of death of burnt bodies under suspicious circumstances. The key questions that arise at the time of investigation include: 1  Was the person alive or dead prior to fire accident?  Did the victim die because of burn?  If death was not related to burns, could burns play a role in causing death?  Were the burns sustained accidentally, did the person commit suicide or was the person murdered?  Are the circumstances suggesting an attempt to conceal crime?  How was the fire started?  How was the victim identified?  In case of mass fatalities, who died first? Postmortem burning of corpses is supposed to be one of the ways to hide a crime. Differentiating the actual cause of death in burn patients is therefore important. Medical examiners usually focus on the defining the changes that occur in tissues while forensic anthropologists deal with the changes related to the bone with or without any the influence of other tissues. Under the circumstances of fire, differentiating the perimortem trauma from that of postmortem cause of bone fractures is vital in determining the cause and motive of death

  18. Chemical and Common Burns in Children.

    2017-05-01

    Burns are a common cause of preventable morbidity and mortality in children. Thermal and chemical burns are the most common types of burns. Their clinical appearance can be similar and the treatment is largely similar. Thermal burns in children occur primarily after exposure to a hot surface or liquid, or contact with fire. Burns are typically classified based on the depth and total body surface area, and the severity and onset of the burn can also depend on the temperature and duration of contact. Chemical burns are caused by chemicals-most commonly acids and alkalis-that can damage the skin on contact. In children, the most common cause of chemical burns is from household products such as toilet bowl cleaners, drain cleaners, detergents, and bleaches. Mild chemical burns generally cause redness and pain and can look similar to other common rashes or skin infections, whereas severe chemical burns are more extreme and may cause redness, blistering, skin peeling, and swelling.

    2017-01-01

    The classical concept of social support has recently become of relevance again, particularly in the context of traumatized patient groups, which include refugees and migrants. This article summarizes the evidence from social support research, e. g. different types of positive effects as well as context, gender and cultural aspects. These aspects are highlighted by means of studies stemming from applied healthcare research and thus describe a wide range of health effects, e.g. increased well-being and reduced depressive symptoms, improved functional abilities, better immune status and longevity. Two new trauma-specific differentiations of the social support concept are introduced: societal acknowledgement as a trauma survivor and disclosure of traumatic experiences. Against this background several implications for working with refugees arise: promotion of self-efficacy and posttraumatic maturation as well as the treatment of mental disorders show considerable benefits from focusing on social support. Finally, possibilities emerging from digital communication media are discussed, which are particularly relevant in this context.

    2009-12-01

    Full Text Available The primary aim of this paper is to provide a brief review of the existing literature investigating the relationship between chronic pain and the Posttraumatic Stress Disorder (PSTD. There is a growing body of research that indicates that PSTD and chronic pain frequently co-occur, and that both conditions may interact in such a way as to negatively impact the course and outcome of the treatment of either disorder. People with both health problems tend to have greater distress and impairment compared to those with only one of these conditions. In recent years, several important conceptual developments and potential mechanisms have been proposed on how and why these disorders often co-occur and how they can interact with one another. The research suggests that variables such as fear and avoidance, anxiety sensitivity, and catastrophizing, as well as general and specific psychological and biological features, may help account for the development and maintenance of both conditions.

    In order to be useful, animal models should be reproducible and consistent regardless of sampling bias, investigator creating burn, and burn location. We determined the variability in burn depth based on biopsy location, burn location and investigator in a porcine model of partial thickness burns. 24 partial thickness burns (2.5 cm by 2.5 cm each) were created on the backs of 2 anesthetized pigs by 2 investigators (one experienced, one inexperienced) using a previously validated model. In one of the pigs, the necrotic epidermis covering each burn was removed. Five full thickness 4mm punch biopsies were obtained 1h after injury from the four corners and center of the burns and stained with Hematoxylin and Eosin and Masson's trichrome for determination of burn depth by a board certified dermatopathologist blinded to burn location and investigator. Comparisons of burn depth by biopsy location, burn location and investigator were performed with t-tests and ANOVA as appropriate. The mean (SD) depth of injury to blood vessels (the main determinant of burn progression) in debrided and non-debrided pigs pooled together was 1.8 (0.3)mm, which included 75% of the dermal depth. Non-debrided burns were 0.24 mm deeper than debrided burns (PBurn depth increased marginally from cephalic to caudal in non-debrided burns, but showed no statistical differences for these locations, in debrided burns. Additionally, there were also no statistical differences in burn depths from midline to lateral in either of these burn types. Burn depth was similar for both investigators and among biopsy locations. Burn depth was greater for caudal locations in non-debrided burns and overall non-debrided burns were deeper than debrided burns. However, burn depth did not differ based on investigator, biopsy site, and medial-lateral location. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available Burn demographics, prevention and care have changed considerably since the 1970s. The objectives were to 1 identify new and confirm previously described changes, 2 make comparisons to the American Burn Association National Burn Repository, 3 determine when the administration of fluids in excess of the Baxter formula began and to identify potential causes, and 4 model mortality over time, during a 36-year period (1974-2009 at the Harborview Burn Center in Seattle, WA, USA.14,266 consecutive admissions were analyzed in five-year periods and many parameters compared to the National Burn Repository. Fluid resuscitation was compared in five-year periods from 1974 to 2009. Mortality was modeled with the rBaux model. Many changes are highlighted at the end of the manuscript including 1 the large increase in numbers of total and short-stay admissions, 2 the decline in numbers of large burn injuries, 3 that unadjusted case fatality declined to the mid-1980s but has changed little during the past two decades, 4 that race/ethnicity and payer status disparity exists, and 5 that the trajectory to death changed with fewer deaths occurring after seven days post-injury. Administration of fluids in excess of the Baxter formula during resuscitation of uncomplicated injuries was evident at least by the early 1990s and has continued to the present; the cause is likely multifactorial but pre-hospital fluids, prophylactic tracheal intubation and opioids may be involved.1 The dramatic changes include the rise in short-stay admissions; as a result, the model of burn care practiced since the 1970s is still required but is no longer sufficient. 2 Fluid administration in excess of the Baxter formula with uncomplicated injuries began at least two decades ago. 3 Unadjusted case fatality declined to ∼6% in the mid-1980s and changed little since then. The rBaux mortality model is quite accurate.

    Herniation of abdominal viscera into the pericardial space is a rare occurrence involving a sacless entry through a rent in the pericardial portion of the diaphragm's central tendon. Intrapericardial diaphragmatic hernia is often overlooked both clinically and radiologically and more pressing cardiorespiratory and orthopaedic abnormalities are addressed. The traumatic patient presented here had air shadows above the diaphragm on his chest radiograph. Chest computed tomography showed displacement of heart and air-filled mass, suspicious of a bowel loop, in the pericardial sac. A diagnosis of intrapericardial hernia was made in this patient who was haemodynamically unstable. The diaphragmatic tear was surgically repaired and the patient's postoperative course was uncomplicated.

    Burn injuries put a huge financial burden on patients and healthcare systems. They are the 8th leading cause of mortality and the 13th most common cause of morbidity in our country. We used data from our Burn Registry Program to evaluate risk factors for mortality and lethal area fifty percent (LA50) in all burn patients admitted over two years. We used multiple logistic regressions to identify risk factors for mortality. LA50 is a reliable aggregate index for hospital care quality and a good measure for comparing results, also with those of other countries. 28,690 burn patients sought medical attention in the Emergency Department, and 1721 of them were admitted. Male to female ratio was 1,75:1. 514 patients were under 15 years old. Median age was 25 (range: 3 months - 93 years). Overall, probability of death was 8.4%. LA50 was 62.31% (CI 95%: 56.57-70.02) for patients aged 15 and over and 72.52% (CI 95%: 61.01-100) for those under 15. In the final model, we found that Adjusted OR was significant for age, female sex, TBSA and inhalation injury (P pay special attention to these variables, especially in prevention programs, to reduce mortality and improve patient outcome. Children have better outcome than adults given equal burn size. Suicide rates are higher for women than men in our country.

  6. Telemedicine and burns: an overview.

    Access to specialized burn care is becoming more difficult and is being restricted by the decreasing number of specialized burn centers. It is also limited by distance and resources for many patients, particularly those living in poverty or in rural medically underserved communities. Telemedicine is a rapidly evolving technology related to the practice of medicine at a distance through rapid access to remote medical expertise by telecommunication and information technologies. Feasibility of telemedicine in burn care has been demonstrated by various centers. Its use facilitates the delivery of care to patients with burn injuries of all sizes. It allows delivery of acute care and can be appropriately used for a substantial portion of the long-term management of patients after a burn by guiding less-experienced surgeons to treat and follow-up patients more appropriately. Most importantly, it allows better effective triage which reduces unnecessary time and resource demanding referrals that might overwhelm system capacities. However, there are still numerous barriers to the implementation of telemedicine, including technical difficulties, legal uncertainties, limited financial support, reimbursement issues, and an inadequate evidence base of its value and efficiency.

  7. Introduction to burning plasma physics

    International Nuclear Information System (INIS)

    Momota, Hiromu

    1982-01-01

    The free energy of fusion-produced charged particles, the critical plasma Q-value for the thermal instability, and the Cherenkov's emission are discussed. The free energy of fusion-produced charged particles is large even in DT burning plasma. The primary role of fusion-produced energetic charged particles is the heating of fuel plasma. If the charged particle heating is large, burning may be thermally unstable. A zero dimensional analysis shows that the critical plasma Q-values for this thermal instability are nearly 5 for DT burning plasma of 14 keV and 1.6 for D-He 3 burning plasma of 60 keV. These critical plasma Q-values are small as compared to that required for commercial reactors. Then, some methods of burning-control should be introduced to fusion plasma. Another feature of energetic charged particles may be Cherenkov's emission of various waves in fusion plasma. The relationship between this micro-instability and transport phenomena may be the important problem to be clarified. The fusion-produced energetic charged particles have large Larmor radii, and they may have effects on balooning mode instability. (Kato, T.)

    To evaluate magnetic resonance imaging (MRI) findings of cevical injuries. MRI studies of 34 patients with cervical spinal injuries were analyzed retrospectively. All MRI scans were obtained with an 1.0T superconductive MRI scanner (Siemens Magnetom 42SPE) and their findings were analyzed regarding the spinal cord, bony spine, ligaments, and intervertebral disks. A variety of abnormal findings were detected: 25 cord abnormalities including cord compression (15 cases), cord edema (4 cases), syringomyelia (4 cases), myelomalacia (1 case), and hemorrhagic contusion (1 case), 18 ligamentous injuries, 22 disk herniations (9 post-traumatic, 13 chronic degenerative), 11 spine fractures, and 4 subluxations. MRI is useful in evaluating the spinal cord itself, in depicting ligamentous injuries, in establishing the presence of disc herniation, and in assessing the alignment of cervical spine

    2014-01-01

    The literature surrounding pediatric burns has focused on inpatient management. The goal of this study is to characterize the population of burned children treated as outpatients and assess outcomes validating this method of burn care. A retrospective review of 953 patients treated the burn clinic and burn unit of a tertiary care center. Patient age, burn etiology, burn characteristics, burn mechanism, and referral pattern were recorded. The type of wound care and incidence of outcomes including subsequent hospital admission, infection, scarring, and surgery served as the primary outcome data. Eight hundred and thirty children were treated as outpatients with a mean time of 1.8 days for the evaluation of burn injury in our clinic. Scalds accounted for 53% of the burn mechanism, with burns to the hand/wrist being the most frequent area involved. The mean percentage of TBSA was 1.4% for the outpatient cohort and 8% for the inpatient cohort. Burns in the outpatient cohort healed with a mean time of 13.4 days. In the outpatient cohort, nine (1%) patients had subsequent admissions and three (0.4%) patients had concern for infection. Eight patients from the outpatient cohort were treated with excision and grafting. The vast majority of pediatric burns are small, although they may often involve more critical areas such as the face and hand. Outpatient wound care is an effective treatment strategy which results in low rates of complications and should become the standard of care for children with appropriate burn size and home support.

    After scalds, flame burns have been considered the next most common mode of burn injury in childhood. Recent experience in the authors' unit suggested that contact burns were becoming more frequent. The authors sought to determine the contemporary frequency of different burn modalities in children presenting to a burns unit. A retrospective review of 3621 children treated in the burns unit, both ambulatory and inpatient, at the authors' institution between January 2003 and December 2007 was performed. Patients were identified using the Burns Unit database. Data collected included age, gender, burn etiology and site, TBSA, and whether operative surgery was required. Of the 3515 patients eligible for inclusion, scalds accounted for 55.9%, contact 30.5%, and flame 7.9% of all burns. Contact burns were shown to be consistently more frequent than flame burns for every year of the study (z = 17.30, P burns, reflecting the variety of mechanisms involved. The data suggest a change in the historical pattern of pediatric burns previously reported in the literature. These findings have implications for public health awareness and burns prevention campaigns.

  11. Neuronal Plasticity Associated with Burn Injury and Its Relevance for Perception and Management of Pain in Burn Patients

    Directory of Open Access Journals (Sweden)

    Terence J Coderre

    2000-01-01

    Full Text Available Through the introduction of the gate control theory and various subsequent works, Ronald Melzack has inspired many investigators worldwide to realize two important facts about pain. First, incoming pain messages are subject to both negative and positive modulation, which significantly affect its perception. Second, the progression of knowledge about the basic mechanisms underlying persistent and chronic pain is critically dependent on the increased understanding of the complexity of the symptoms experienced by pain patients. The present paper examines these two very important issues in an effort to understand better the mechanisms that underlie the pain suffered by burn patients. The physiological responses to burn injury involve many different mediators and mechanisms, all of which contribute to pain perception and development of neuronal plasticity underlying short and long term changes in pain sensitivity. While experimental burn injuries in humans and animals are typically well controlled and mild, in burn victims, the severity is much more variable, and clinical care involves repeated traumas and manipulations of the injured sites. Recurrent inputs from damaged and redamaged tissue impinge on a nervous system that becomes an active participant in the initiation of changes in sensory perception and maintenance of long term sensory disturbances. Recently acquired experimental evidence on postburn hyperalgesia, central hyperexcitability and changes in opioid sensitivity provides strong support that burn patients need an analgesic approach aimed at preventing or reducing the 'neural' memory of pain, including the use of more than one treatment modality. Burn injuries offer a unique opportunity to combine experimental and clinical research to understand pain mechanisms better. Over the years, Ronald Melzack has insisted that one of the most laudable enterprises in research is to span the gap between these two often separate worlds.

    Domestic and industrial swallowing of caustic substances can cause acute and chronic injuries. In the acute phase of care, focus is on the immediate control of tissue damage and perforation, and in the chronic phase, the focus is on the treatment of pharyngeal narrowing and impaired swallowing. The patients of this report were an 18-year-old man and a 20-year-old woman, who had esophageal burns after ingesting chemicals, and for solving their nutritional problems, such as difficulty in swallowing, they had underwent surgery. Patients had continued follow-up after surgery. Treatment of esophageal burn lesions is by immediate and delayed removing of damage outcomes.

    A new reduced size ITER-RC superconducting tokamak concept is proposed with the goals of studying burn physics either in an inductively driven standard tokamak (ST) mode of operation, or in a quasi-steady state advanced tokamak (AT) mode sustained by non-inductive means. This is achieved by reducing the radiation shield thickness protecting the superconducting magnet by 0.34 m relative to ITER and limiting the burn mode of operation to pulse lengths as allowed by the TF coil warming up to the current sharing temperature. High gain (Q≅10) burn physics studies in a reversed shear equilibrium, sustained by RF and NB current drive techniques, may be obtained. (author)

    When traumatic wounds are quickly and accurately treated, morbidity and costs can be significantly decreased. Several factors, such as time delay between injury and treatment, the degree of contamination, extension and depth of the wound, and the mechanism of injury, influence the treatment and prognosis and stress the importance of a patient-specific approach. Although all traumatic wounds are contaminated, antibiotic therapy is seldom required if correct wound management is installed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Burn as a traumatic life incident manifests severe pain and psychological problems. Specific instruments are needed to evaluate burn patients' psychological issues related to the injury. The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES). In this cross-sectional study, convenience sampling method was utilized to select 55 Iranian hospitalized burn patients. Combined translation was utilized for translating scales. Alpha cronbach, item-total correlation, convergent and discriminative validity were evaluated. The Cronbach's α for both BSPAS- and IES-Persian version was 0.96. Item-total correlation coefficients ranged from 0.70 to 0.90. Convergent construct validity was confirmed by indicating high correlation between the scales designed to measure the same concepts. The mean score of BSPAS- and IES-Persian version was lower for individuals with a lower TBSA burn percentage which assessed discriminative construct validity of scales. BSPAS- and IES-Persian version showed high internal consistency and good validity for the assessment of burn psychological outcome in hospitalized burn patients. Future studies are needed to determine repeatability, factor structure, sensitivity and specificity of the scales. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    2015-05-01

    Every year an estimated 42 million people worldwide suffer a mild traumatic brain injury (MTBI) or concussion. More severe traumatic brain injury (TBI) is a well-established risk factor for a variety of neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS). Recently, large epidemiological studies have additionally identified MTBI as a risk factor for dementia. The role of MTBI in risk of PD or ALS is less well established. Repetitive MTBI and repetitive sub-concussive head trauma have been linked to increased risk for a variety of neurodegenerative diseases including chronic traumatic encephalopathy (CTE). CTE is a unique neurodegenerative tauopathy first described in boxers but more recently described in a variety of contact sport athletes, military veterans, and civilians exposed to repetitive MTBI. Studies of repetitive MTBI and CTE have been limited by referral bias, lack of consensus clinical criteria for CTE, challenges of quantifying MTBI exposure, and potential for confounding. The prevalence of CTE is unknown and the amount of MTBI or sub-concussive trauma exposure necessary to produce CTE is unclear. This review will summarize the current literature regarding the epidemiology of MTBI, post-TBI dementia and Parkinson's disease, and CTE while highlighting methodological challenges and critical future directions of research in this field.

    Stroke is the second most common cause of death and the leading cause of adult disability. Both stroke patients and their family can therefore experience increased traumatic stress level. The participants are close relatives of patients (n=65) who had a first time stroke (CRPWS) hospitalized. A control group (CG) (n=61), who had no history of chronic illness in their family and had at least one traumatic life event experience. The National Institutes of Health Stroke Scale, Modified Rankin Scale, Personal Information Form, Life Events Checklist, Traumatic Stress Symptom Scale, and Multidimensional Scale of Perceived Social Support, were used in the study. We found no significant association between NIHSS and MRS of patients and traumatic stress level of the family member. The traumatic stress level was significantly higher in the CRPWS group than in the CG group. Traumatic stress level was higher in women than men and was not associated with perceived social support in the CRPWS group. The traumatic stress level of the relatives was not associated with the clinical features of the stroke patients. In the early phase, after the diagnosis of stroke, psychological support may be important to prevent CRPWS from PTSD.

    To identify the risk factors for post-traumatic amnesia (PTA) and to document the incidence of PTA after mild traumatic brain injuries. 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.

    Absract: In view of the world-wide problem of energy sustainability and greenhouse gas production (carbon dioxide), it is timely to review the issues involved in generating heat and power from all fuels and especially new (to the UK) solid fuels, including high moisture fuels such as wood, SRF, oil shale, tar sands and brown coal, which will become major international fuels as oil and gas become depleted. The combustion properties of some of these materials are significantly different from traditional coal, oil and gas fuels, however the technology proposed herein is also applicable to these conventional fuels. This paper presents some innovative combustion system options and the associated technical factors that must be considered for their implementation. For clarity of understanding, the novel concepts will be largely presented in terms of a currently developing solid fuel market; biomass wood chips. One of the most important characteristics of many solid fuels to be used in the future (including oil shale and brown coal) is their high moisture content of up to 60%. This could be removed by utilising low grade waste heat that is widely available in industry to dry the fuel and thus reduce transport costs. Burning such dried wood for power generation also increases the energy available from combustion and thus acts as a thermal transformer by upgrading the low grade heat to heat available at combustion temperatures. The alternative approach presented here is to recover the latent heat by condensing the extrinsic moisture and the water formed during combustion. For atmospheric combustion, the temperature of the condensed combustion products is below the dew point at about 55-65 o C and is only suitable for recovery in an efficient district heating system. However, in order to generate power from the latent heat, the condensation temperature must be increased to the level where the heat can be used in the thermodynamic power cycle. This can be achieved by

  6. Molecular mechanisms of cognitive dysfunction following traumatic brain injury.

    Traumatic brain injury (TBI) results in significant disability due to cognitive deficits particularly in attention, learning and memory, and higher-order executive functions. The role of TBI in chronic neurodegeneration and the development of neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS) and most recently chronic traumatic encephalopathy (CTE) is of particular importance. However, despite significant effort very few therapeutic options exist to prevent or reverse cognitive impairment following TBI. In this review, we present experimental evidence of the known secondary injury mechanisms which contribute to neuronal cell loss, axonal injury, and synaptic dysfunction and hence cognitive impairment both acutely and chronically following TBI. In particular we focus on the mechanisms linking TBI to the development of two forms of dementia: AD and CTE. We provide evidence of potential molecular mechanisms involved in modulating Aβ and Tau following TBI and provide evidence of the role of these mechanisms in AD pathology. Additionally we propose a mechanism by which Aβ generated as a direct result of TBI is capable of exacerbating secondary injury mechanisms thereby establishing a neurotoxic cascade that leads to chronic neurodegeneration.

SPT refers to the anxiety-related cognitive, emotional, and behavioral reactions to pain that resemble the features of a traumatic stress reaction.Methods: In Study 1, a preliminary set of 79 items was administered to 116 participants. The data were analyzed by using combined nonparametric and parametric item response theory resulting in a 12-item scale with a one-factor structure and good preliminary psychometric properties. Studies 2 and 3 assessed the factor structure and psychometric properties of the SPTS-12 in a community sample of 823 participants (268 with chronic pain and 555 pain-free and a clinical sample of 345 patients (126 with chronic post-surgical pain, 92 with other nonsurgical chronic pain, and 127 with no chronic pain at least 6 months after undergoing coronary artery bypass graft surgery, respectively. Results: The final SPTS-12 derived from Study 1 comprised 12 items that discriminated between individuals with different levels of SPT, with the overall scale showing good to very good reliability and validity. The results from Studies 2 and 3 revealed a one-factor structure for chronic pain and pain-free samples, excellent reliability and concurrent validity, and moderate convergent and discriminant validity. Conclusion: The results of the three studies provide preliminary evidence for the validity and reliability of the SPTS-12.

    Full Text Available Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS, which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder.

    Infection is a major problem in burn care and especially when it is due to bacteria with hospital-acquired multi-resistance to antibiotics. Moreover, when these bacteria are Gram-negative organisms, the most effective molecules are 20 years old and there is little hope of any new product available even in the distant future. Therefore, it is obvious that currently available antibiotics should not be misused. With this aim in mind, the following review was conducted by a group of experts from the French Society for Burn Injuries (SFETB). It examined key points addressing the management of antibiotics for burn patients: when to use or not, time of onset, bactericidia, combination, adaptation, de-escalation, treatment duration and regimen based on pharmacokinetic and pharmacodynamic characteristics of these compounds. The authors also considered antibioprophylaxis and some other key points such as: infection diagnosis criteria, bacterial inoculae and local treatment. French guidelines for the use of antibiotics in burn patients have been designed up from this work. Copyright © 2009 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available Background: Diabetes mellitus is a common chronic metabolic disease which have numerous physical effects for patients. Objective: The aim of this study was to determine the prevalence of subjective xerostomia and burning mouth of patients with type 2 diabetes mellitus in cities of Sari and Qaemshahr. Methods: In this descriptive-analytic study, totally 1455 patients with type 2 diabetes mellitus with complain of xerostomia and/or burning mouth which had referred to diabetes clinic in Sari and Qaemshahr were examined in 2016. For every patient asked about chronic xerostomia and burning mouth and if the answer was positive, the oral examination was done to ensure the absence of mucosal lesions and find signs of xerostomia. Then, xerostomia questionnaire was completed by patients suffering from dry mouth. Finally, the information was statistically analyzed by T test and chi square test. Findings: Prevalence of burning mouth was found 111 (7.6% in diabetic patients that in the women were significantly higher than in men (P<0.0001. Prevalence of xerstomia patients was found 239 (16.4% that was not significant between the male and female. There was a significant correlation between burning mouth and xerostomia with FBS and HbA1c in diabetic patients (P<0.0001. Conclusion: Possibility of burning mouth, and xerostomia will increase in the diabetic patients with low metabolic control which can cause more severe side effects related to oral health.

    Out of 1415 patients treated as inpatients at Al-Babtain Center for Burns and Plastic Surgery, Ibn Sina Hospital, Kuwait spanning over a period of 6 years from June 1992 to June 1998, 102 developed clinically and microbiologically proven septicaemia. Only 15 out of them had either single or multiple episodes of septicaemia due to Pseudomonas aeruginosa and were studied during their stay in the hospital. Five of them were males and 10 females, with a mean age of 26 years (range 3-51 years) and mean total body surface area of burns (TBSA) of 66% (range 25-90%). All of them had flame burns and resuscitation was found to be difficult in eight patients either due to delayed hospitalization or accompanied inhalation injury. Seven patients were intubated, four due to inhalation injury and three for septicaemic complications. Among the 15 patients under study, a total of 36 septicaemic episodes were detected of which 21 were due to P. aeruginosa. This organism was found in the first episodes in nine patients, in second episodes in six, in third episodes in three and fourth, fifth and sixth episodes in one patient, each at a variable postburn day. Ten patients had 38 sessions of excision and skin grafting, six of them survived. Nine of the 15 patients under study died due to septicaemia, but only six of them had P. aeruginosa as the last isolate. Except for one, all patients had > 40% TBSA burn, two had difficult resuscitation and four were intubated. The day of death varied between 3 to 52 days postburn (mean 19 days). This study showed that females with flame burns are susceptible to P. aeruginosa septicaemia. Difficult resuscitation and intubation also proved to be important risk factors. Septicaemia could occur quite early in the postburn days and the mortality due to this organism was quite high. Early excision and grafting with other effective management may result in a better outcome.

    The acute and long-term consequences of traumatic brain injury (TBI) have received increased attention in recent years. In this Review, we discuss the neuropathology and neural mechanisms associated with TBI, drawing on findings from sports-induced TBI in athletes, in whom acute TBI damages axons and elicits both regenerative and degenerative tissue responses in the brain and in whom repeated concussions may initiate a long-term neurodegenerative process called dementia pugilistica or chronic traumatic encephalopathy (CTE). We also consider how the neuropathology and neurobiology of CTE in many ways resembles other neurodegenerative illnesses such as Alzheimer's disease, particularly with respect to mismetabolism and aggregation of tau, β-amyloid, and TDP-43. Finally, we explore how translational research in animal models of acceleration/deceleration types of injury relevant for concussion together with clinical studies employing imaging and biochemical markers may further elucidate the neurobiology of TBI and CTE.

    Traumatized refugees often suffer from complex posttraumatic disorders with a high tendency of chronicity. This is due to severe and often repeated traumatization in the course of political persecution on one hand and uprooting and ongoing stress caused by leaving their home country and society and living under an adverse situation in exile on the other hand. This article shows how positive and negative factors going along with migration interfere with the course of the traumatic process and the therapeutic possibilities and how the therapeutic process can be adjusted to the situation.

    Full Text Available INTRODUCTION Interest for traumatic thoracic aorta rupture stems from the fact that its number continually increases, and it can be rapidly lethal. OBJECTIVE The aim of this study is to present early and long term results as well as experiences of our team in surgical treatment of traumatic thoracic aorta rupture. METHOD Our retrospective study includes 12 patients with traumatic thoracic aorta rupture treated between 1985 and 2007. There were 10 male and two female patients of average age 30.75 years (18-74. RESULTS In six cases, primary diagnosis was established during the first seven days days after trauma, while in 6 more than one month later. In 11 cases, classical open surgical procedure was performed, while endovascular treatment was used in one patient. Three (25% patients died, while two (16.6% had paraplegia. Nine patients (75% were treated without complications, and are in good condition after a mean follow-up period of 9.7 years (from one month to 22 years. CONCLUSION Surgical treatment requires spinal cord protection to prevent paraplegia, using cardiopulmonary by-pass (three of our cases or external heparin-bonded shunts (five of our cases. Cardiopulmonary by-pass is followed with lower incidence of paraplegia, however it is not such a good solution for patients with polytrauma because of hemorrhage. The endovascular repair is a safe and feasible procedure in the acute phase, especially because of traumatic shock and polytrauma which contributes to higher mortality rate after open surgery. On the other hand, in chronic postrauamatic aortic rupture, open surgical treatment is connected with a lower mortality rate and good long-term results. There have been no published data about long-term results of endovascular treatment in the chronic phase.

    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.

    Studies of posttraumatic stress disorder (PTSD) are complicated by wide variability in the intensity and duration of prior stressors in patient participants, secondary effects of chronic psychiatric illness, and a variable history of treatment with psychiatric medications. In magnetic resonance imaging (MRI) studies, patient samples have often been small, and they were not often compared to similarly stressed patients without PTSD in order to control for general stress effects. Findings from these studies have been inconsistent. The present study investigated whole-brain microstructural alterations of white matter in a large drug-naive population who survived a specific, severe traumatic event (a major 8.0-magnitude earthquake). Using diffusion tensor imaging (DTI), we explored group differences between 88 PTSD patients and 91 matched traumatized non-PTSD controls in fractional anisotropy (FA), as well as its component elements axial diffusivity (AD) and radial diffusivity (RD), and examined these findings in relation to findings from deterministic DTI tractography. Relations between white matter alterations and psychiatric symptom severity were examined. PTSD patients, relative to similarly stressed controls, showed an FA increase as well as AD and RD changes in the white matter beneath left dorsolateral prefrontal cortex and forceps major. The observation of increased FA in the PTSD group suggests that the pathophysiology of PTSD after a specific acute traumatic event is distinct from what has been reported in patients with several years duration of illness. Alterations in dorsolateral prefrontal cortex may be an important aspect of illness pathophysiology, possibly via the region's established role in fear extinction circuitry. Use-dependent myelination or other secondary compensatory changes in response to heightened demands for threat appraisal and emotion regulation may be involved.

    2017-05-01

    Chemical burns can lead to serious health outcomes. Previous studies about chemical burns have been performed based on burn center data so these studies have provided limited information about the incidence of chemical burns at the national level. The aim of this study was to evaluate the incidence and characteristics of chemical burns using nationwide databases. A cohort representing the Korean population, which was established using a national health insurance database, and a nationwide workers' compensation database were used to evaluate the incidence and characteristics of chemical burns. Characteristics of the affected body region, depth of burns, industry, task, and causative agents were analyzed from two databases. The incidence of chemical burns was calculated according to employment status. The most common regions involving chemical burns with hospital visits were the skin followed by the eyes. For skin lesions, the hands and wrists were the most commonly affected regions. Second degree burns were the most common in terms of depth of skin lesions. The hospital visit incidence was 1.96 per 10,000 person-year in the general population. The compensated chemical burns incidence was 0.17 per 10,000 person-year. Employees and the self-employed showed a significantly increased risk of chemical burns undergoing hospital visits compared to their dependents. Chemical burns on the skin and eyes are almost equally prevalent. The working environment was associated with increased risk of chemical burns. Our results may aid in estimating the size of the problem and prioritizing prevention of chemical burns. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    2016-05-01

    The impact of war and violence on the mental and physical health of the civilian population is immense. Traumatization is often experienced sequentially, which leads to a higher risk for developing trauma-related disorders (PTSD, depression, chronic pain).Refugees traumatized by war experience specific stressors related to their status of residence (e. g., application hearing, length of the asylum procedure). Together with limited access to health care, these constitute additional risk factors for developing somatic and psychological illnesses.Adequate treatment for this highly vulnerable group requires a multimodal approach facilitated by translators. According to the S3 guidelines (S3-Richtlinien), trauma-adapted psychotherapeutic treatment has to be complemented by the activities of social workers, by medical treatment, and by legal advice.

  10. Modelling burned area in Africa

    2010-10-01

    Full Text Available The simulation of current and projected wildfires is essential for predicting crucial aspects of vegetation patterns, biogeochemical cycling as well as pyrogenic emissions across the African continent. This study uses a data-driven approach to parameterize two burned area models applicable to dynamic vegetation models (DVMs and Earth system models (ESMs. We restricted our analysis to variables for which either projections based on climate scenarios are available, or that are calculated by DVMs, and we consider a spatial scale of one degree as the scale typical for DVMs and ESMs. By using the African continent here as an example, an analogue approach could in principle be adopted for other regions, for global scale dynamic burned area modelling.

    We used 9 years of data (2000–2008 for the variables: precipitation over the last dry season, the last wet season and averaged over the last 2 years, a fire-danger index (the Nesterov index, population density, and annual proportion of area burned derived from the MODIS MCD45A1 product. Two further variables, tree and herb cover were only available for 2001 as a remote sensing product. Since the effect of fires on vegetation depends strongly on burning conditions, the timing of wildfires is of high interest too, and we were able to relate the seasonal occurrence of wildfires to the daily Nesterov index.

    We parameterized two generalized linear models (GLMs, one with the full variable set (model VC and one considering only climate variables (model C. All introduced variables resulted in an increase in model performance. Model VC correctly predicts the spatial distribution and extent of fire prone areas though the total variability is underrepresented. Model VC has a much lower performance in both aspects (correlation coefficient of predicted and observed ratio of burned area: 0.71 for model VC and 0.58 for model C. We expect the remaining variability to be attributed to additional

    This invention, a method for ultrasonically determining the depth of a skin burn, is based on the finding that the acoustical impedance of burned tissue differs sufficiently from that of live tissue to permit ultrasonic detection of the interface between the burn and the underlying unburned tissue. The method is simple, rapid, and accurate. As compared with conventional practice, it provides the important advantage of permitting much earlier determination of whether a burn is of the first, second, or third degree. In the case of severe burns, the usual two - to three-week delay before surgery may be reduced to about 3 days or less.

    Full Text Available The hand is ranked among the three most frequent sites of burns scar contracture deformity. One of the major determinants of the quality of life in burns survivors is the functionality of the hands. Burns deformities, although largely preventable, nevertheless do occur when appropriate treatment is not provided in the acute situation or when they are part of a major burns. Reconstructive procedures can greatly improve the function of the hands. Appropriate choice of procedures and timing of surgery followed by supervised physiotherapy can be a boon for a burns survivor.

    Full Text Available Burn injuries are a huge public health issue for children throughout the world, with the majority occurring in developing countries. Burn injuries can leave a pediatric patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Rehabilitation is an essential and integral part of pediatric burn treatment. The aim of this article was to review the literature on pediatric burn rehabilitation from the Medline, CINAHL, and Web of Science databases. An attempt has been made to present the basic aspects of burn rehabilitation, provide practical information, and discuss the goals and conceptualization of rehabilitation as well as the development of rehabilitation philosophy and strategies.

    The number of polymorphs which stained with the dye nitro-blue tetrazolium (NBT "Positive") increased sharply during the first week after burning, reaching levels 4--5 times above values for healthy volunteers. In burns of more than 20% of the body surface a second, smaller increase in the number of NBT "positives" occurred 4 to 6 weeks after burning. The high levels of NBT "positive" polymorphs occurred independently of infection on the burns. A burned patient who died from septicaemia had very low numbers of NBT "positive" polymorphs for 3 weeks before death. PMID:444418

  17. The Use of Glabrous Skins Grafts in the Treatment of Pediatric Palmar Hand Burns.

    An often overlooked, yet useful, technique in the treatment of palmar hand burns is the use of glabrous skin grafting, particularly in dark-skinned individuals. Pediatric palmar burns are a particularly unique subset of burns. The typical split-thickness or full-thickness skin grafts leave a notably different skin texture and pigmentation. It is also known that the psychological aspects of a pediatric burn can be quite burdensome for a child as he or she progresses through childhood and adolescence. For a dark-skinned patient the placement a standard full-thickness skin graft in a nonpigmented palm provides for a constant reminder of a traumatic event. We report a case series of pediatric patients who were managed with glabrous skin grafting from the plantar aspect of the foot. A retrospective review of palmar skin burns requiring grafting at a single pediatric burn center experience over a 2 and a half year time period was performed. Seventeen patients were identified. Our treatment algorithm for deep partial thickness burns first relies on a combination of operative and nonoperative measures to expedite the demarcation of the burn injury. If the burn is full thickness in nature or if a lack of progression of healing is identified within the first 14 days of injury, then skin grafting is recommended. Our technique for performing the graft is described. The average age at time of surgery was 2.05 years (6 months to 6.8 years). Fourteen of the 17 patients had darker skin types (Fitzpatrick Type III-VI) and identified themselves as either Hispanic or African American. The average size of the area requiring skin graft after debridement was 0.94% total body surface area (0.5%-2.0%). Of the patients that were not lost to follow-up, 1 patient required additional grafting after developing a finger contracture for splint noncompliance. Aesthetically, the wounds went on to heal with an excellent pigment match and an inconspicuous donor site. In the management of deep

    A hand represents 3% of the total body surface area. The hands are involved in close to 80% of all burns. The potential morbidity associated with hand burns can be substantial. Imagine a patient carrying a pan of flaming cooking oil to the doorway or someone lighting a room-sized pile of leaves and branches doused with gasoline. It is clear how the hands are at risk in these common scenarios. Not all burn injuries will require surgical intervention. Recognizing the need for surgery is paramount to achieving good functional outcomes for the burned hand. The gray area between second- and third-degree burns tests the skill and experience of every burn/hand surgeon. Skin anatomy and the size of injury dictate the surgical technique used to close the burn wound. In addition to meticulous surgical technique, preoperative and postoperative hand therapy for the burned hand is essential for a good functional outcome. Recognizing the burn depth is paramount to developing the appropriate treatment plan for any burn injury. This skill requires experience and practice. In this article, we present an approach to second- and third-degree hand burns. Copyright © 2014 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.

    Burns to the perineum are frequently exposed to faeces. Diverting colostomy is often described to prevent faecal soiling. Because this technique is invasive with frequent complications, use of non-surgical devices including specifically designed faecal management systems has been reported in perineal burns. In order to standardise the faecal management strategy in patients with perineal burns, a group of French experts was assembled. This group first evaluated the ongoing practice in France by analysing a questionnaire sent to every French burn centre. Based on the results of this study and on literature data, the experts proposed recommendations on the management of perineal burns in adults. Specifically designed faecal management systems are the first-line method to divert faeces in perineal burns. The working group proposed recommendations and an algorithm to assist in decisions in the management of perineal burns in four categories of patients, depending on total burn skin area, depth and extent of the perineal burn. In France, non-surgical devices are the leading means of faecal diversion in perineal burns. The proposed algorithm may assist in decisions in the management of perineal burns. The expert group emphasises that large clinical studies are needed to better evaluate these devices. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    In 2009, the Victoria Department of Sustainability and Environment estimated approximately 430,000 hectares of Victoria Australia were burned by numerous bushfires. Burned Area Emergency Response (BAER) teams from the United States were deployed to Victoria to assist local fire managers. The U.S. Geological Survey Earth Resources Observation and Science Center (USGS/EROS) and U.S. Forest Service Remote Sensing Applications Center (USFS/RSAC) aided the support effort by providing satellite-derived "soil burn severity " maps for over 280,000 burned hectares. In the United States, BAER teams are assembled to make rapid assessments of burned lands to identify potential hazards to public health and property. An early step in the assessment process is the creation of a soil burn severity map used to identify hazard areas and prioritize treatment locations. These maps are developed primarily using Landsat satellite imagery and the differenced Normalized Burn Ratio (dNBR) algorithm.

    Radiation injuries are usually caused by radioactive isotopes in industry. Detonations of nuclear reactors, the use of military nuclear weapons, and terrorist attacks represent a risk of mass burn casualties. Ionizing radiation creates thermal burns, acute radiation syndrome with pancytopenia, and a delayed cutaneous syndrome. After a latency period, skin symptoms appear and the depth of tissue damages increase with dose exposure. The usual burn resuscitation protocols have to be applied. Care of these victims also requires assessment of the level of radiation, plus decontamination by an experienced team. In nuclear disasters, the priority is to optimize the available resources and reserve treatment to patients with the highest probability of survival. After localized nuclear injury, assessment of burn depth and surgical techniques of skin coverage are the main difficulties in a burn centre. Training in medical facilities and burn centres is necessary in the preparation for management of the different types of burn injuries.

    Purpose: To completely process less combustible radioactive wastes with no excess loads on discharge gas processing systems and without causing corrosions to furnace walls. Method: Among combustible radioactive wastes, chlorine-containing less combustible wastes such as chlorine-containing rubbers and vinyl chlorides, and highly heat generating wastes not containing chloride such as polyethylene are selectively packed into packages. While on the other hand, packages of less combustible wastes are charged into a water-cooled jacket type incinerator intermittently while controlling the amount and the interval of charging so that the temperature in the furnace will be kept to lower than 850 deg C for burning treatment. Directly after the completion of the burning, the packed highly heat calorie producing wastes are charged and subjected to combustion treatment. (Yoshihara, H.)

    Wildland fire impacts on surface freshwater resources have not previously been measured, nor factored into regional water management strategies. But, large wildland fires are increasing and raise concerns about fire impacts on potable water. Here we synthesize long-term records of wildland fire, climate, and river flow for 168 locations across the United States. We show that annual river flow changed in 32 locations, where more than 19% of the basin area was burned. Wildland fires enhanced annual river flow in the western regions with a warm temperate or humid continental climate. Wildland fires increased annual river flow most in the semi-arid Lower Colorado region, in spite of frequent droughts in this region. In contrast, prescribed burns in the subtropical Southeast did not significantly alter river flow. These extremely variable outcomes offer new insights into the potential role of wildfire and prescribed fire in regional water resource management, under a changing climate.

    Severe combined burn-blast injury is a great challenge to surgical teams due to its high mortality. It also results in unsightly traumatic tattoos. The aims of these case reports were to clarify the clinical characteristic of the dynamite explosion burn-blast facial injuries and discuss appropriate management of these patients. We report two patients suffering from facial burn-blast injury following dynamite explosion in which after primary stabilization, silver sulfadiazine cream was applied to the wounds and 12 hours later the wounds were cleaned under general anesthesia with vigorous saline solution irrigation and brushing. The foreign particles were meticulously removed from wounds and simultaneous repairing of defects was done with nylon 6-0 sutures. We conclude application of silver sulfadiazine cream on facial burn-blast injury tattoos several hours before surgical removal of particles is highly efficacious in facilitating particle removal and attaining a good result following surgical intervention, and primary repair. Treatment of combined burn-blast tattoos is different from other types of tattoos not associated with burns. Debridement and removal of foreign particles under general anesthesia from skin immediately and primary reconstruction of wounds is essential. We recommend application of the topical agent silver sulfadiazine to wounds about 12 hours before surgical intervention.

    Major burn patients have characteristics that make them especially susceptible to candidemia, but few studies focused on this have been published. The objectives were to evaluate the epidemiological, microbiological and clinical aspects of candidemia in major burn patients, determining factors associated with a poorer prognosis and mortality. We conducted a retrospective observational study of candidemia between 1996 and 2012 in major burn patients admitted to the La Fe University Hospital, Valencia, Spain. The study included 36 episodes of candidemia in the same number of patients, 55.6% men, mean age 37.33 years and low associated comorbidity. The incidence of candidemia varied between 0.26 and 6.09 episodes/1000 days stay in the different years studied. Candida albicans was the most common species (61.1%) followed by Candida parapsilosis (27.8%). Candidemia by C. krusei, C. glabrata or C. tropicalis were all identified after 2004. Central vascular catheter (CVC) was established as a potential source of candidemia in 36.1%, followed by skin and soft tissues of thermal injury (22.2%) and urinary tract (8.3%). Fluconazole was used in 19 patients (52.7%) and its in vitro resistance rate was 13.9%. The overall mortality was 47.2%, and mortality related to candidemia was 30.6%. Factors associated with increased mortality were those related to severe infection and shock. CVC was the most usual focus of candidemia. Fluconazole was the most common antifungal drug administered. The management of candidemia in major burn patients is still a challenge. © 2016 Blackwell Verlag GmbH.

    Traumatic intracranial lesion has been one of the most frequent and serious problem in neurosurgical pathology. Computed tomography made it possible to get prompt diagnosis and surgical intervention of intracranial lesions by its safety, fastness and accuracy. Computed tomographic scan was carried out on 1309 cases at Soonchunhyang Chunan Hospital for 15 months from October 1983 to December 1984. We have reviewed the computed tomographic scans of 264 patients which showed traumatic intracranial lesion. The result were as follows: 1. Head trauma was the most frequent diagnosed disease using computed tomographic scans (57.8%) and among 264 cases the most frequent mode of injury was traffic accident (73.9%). 2. Skull fracture was accompanied in frequency of 69.7% and it was detected in CT in 38.6%: depression fracture was more easily detected in 81%. 3. Conutercoup lesion (9.5%) was usually accompanied with temporal and occipital fracture, and it appeared in lower incidence among pediatric group. 4. Intracranial lesions of all 264 cases were generalized cerebral swelling (24.6%), subdural hematoma (22.3%), epidural hematoma (20.8%), intracerebral hematoma (6.1%), and subarachnoid hemorrhage (3.0%). 5. The shape of hematoma was usually biconvex (92.7%) in acute epidural hematoma and cresentic (100%) in acute subdural hematoma, but the most chronic the case became, they showed planoconvex and bicconvex shapes. 6. Extra-axial hematoma was getting decreased in density as time gone by. 7. Hematoma density was not in direct proportion to serum hemoglobin level as single factor.

    There is limited English literature describing the experience of a civilian hospital managing blast-related burn injuries. As the largest regional burn unit, we reviewed our cases with the aim of identifying means to improve current management. A 6-year retrospective analysis of all patients coded as sustaining blast-related burns was conducted through the unit's burns database. Medical case notes were reviewed for information on burn demographics, management and outcomes. 42 patients were identified. Male to female ratio was 37:5. Age range was 12-84 years, (mean=33 years). Total body surface area (%TBSA) burn ranged from 0.25% to 60%, (median=1%). The most common burn injury was flame (31/42, 73.8%). Gas explosions were the most common mechanism of injury (19 cases; 45.2%). 7/42 cases (16.7%) had full ATLS management pre-transfer to the burns unit. The Injury Severity Score (ISS) ranged from 0-43 (median=2). 17/42 (40.4%) patients required admission. 37/36 (88.1%) patients were managed conservatively of which 1 patient later required surgery due to deeper burns. 5/42 (11.9%) patients required surgical management at presentation and these were noted to be burns with >15% TBSA requiring resuscitation. One case required emergency escharotomies and finger amputations. All patients survived their burn injuries. Blast-related burn injuries are generally uncommon in the civilian setting. Following proper assessment, most of these cases can be deemed as minor injuries and managed conservatively. Improvement in burns management education and training at local emergency departments would provide efficient patient care and avoid unnecessary referrals to a burns unit.

    Lignites burning in the Greek Coal Power Plants (CPP) contain naturally occurring radionuclides mainly arising from the uranium series. Radium-226 concentrations in lignites burning in the three Coal Power Plants of the 3.02 GW energy centre, the greatest in Greece (Valley of Ptolemais, North Greece), varied from about 30 to 132 Bq kg -1 (average 65.5 Bq kg -1 . About 1.3 % of 226 Ra is discharged to the environment in particulate form - fly ash - by the stacks of thermal power stations, burning coal at a rate 14.3 Mt (GH y) -1 . The collective effective dose equivalent (EDE) commitment to the population 44400 living in the region of these plants, due to inhalation was estimated to be 0.13 man Sv y -1 , that is an order of magnitude higher than that recommended for such a population. Doses from inhaled radon and radon progeny might cause an excess of 3-7 cancer deaths this year. (author)

  13. Minocycline attenuates mechanical allodynia and central sensitization following peripheral second-degree burn injury.

    Science.gov (United States)

    Chang, Yu-Wen; Waxman, Stephen G

    2010-11-01

    Burn injury induces severe pain that can be refractory to existing pharmacotherapies. The underlying mechanism of burn pain remains unclear. We previously established an animal model and reported that unilateral burn injury induces chronic and bilateral mechanical allodynia, which is associated with central sensitization and microglial activation in the spinal cord dorsal horn. Modulation of the activity of microglia and p38 mitogen-activated protein kinase (MAPK) has been shown to ameliorate neuropathic pain in several nerve-injury pain models. In the present study, we show in this rat model that daily treatment with the microglial inhibitor minocycline (10 mg/kg), administered at the time of burn injury and for 7 days thereafter, significantly attenuates ipsilateral and contralateral allodynia as assessed up to 1 month following burn injury. These sensory changes are paralleled by significant suppression of evoked hyperexcitability of dorsal-horn neurons and of the expression of phosphorylated p38 (phospho-p38) in OX42+ microglial cells within the dorsal horn. Our results suggest that modulation of inflammation at early times after burn injury may have long-lasting effects, attenuating central neuropathic mechanisms which contribute to pain after burn injury. We demonstrate, in a rodent model of burn-associated pain, that the microglial inhibitor minocycline, delivered at the time of burn injury and for 1 week thereafter, has long-lasting effects, attenuating microglial activation and neuronal hyperresponsiveness in the dorsal horns, and ameliorating allodynia for at least 1 month.

    Traumatic brain injury is a worldwide health issue and a significant cause of preventable deaths and disabilities. We aimed to describe population-based data on intensive care treated traumatic brain injury in Iceland over 15 years period. Retrospective review of all intensive care unit admissions due to traumatic brain injury at The National University Hospital of Iceland 1999-2013. Data were collected on demographics, mechanism of injury, alcohol consumption, glasgow come scale upon admission, Injury Severity Scoring, acute physiology and chronic health evaluation II score, length of stay, interventions and mortality (defined as glasgow outcome score one). All computerized tomography scans were reviewed for Marshall score classification. Intensive care unit admissions due to traumatic brain injury were 583. The incidence decreased significantly from 14/100.000/year to 12/100.000/year. Males were 72% and the mean age was 41 year. Majority of patients (42%) had severe traumatic brain injury. The most common mechanism of injury was a fall from low heights (36.3%). The mortality was 18.2%. Increasing age, injury severity score, Marshall score and acute physiology and chronic health evaluation II score are all independent risk factors for death. Glasgow coma scale was not an independent prognostic factor for outcome. Incidence decreased with a shift in injury mechanism from road traffic accidents to falls and an increased rate of traumatic brain injury in older patients following a fall from standing or low heights. Mortality was higher in older patients falling from low heights than in younger patients suffering multiple injuries in road traffic accidents. Age, injury severity score, acute physiology and chronic health evaluation II score and Marshall score are good prognostic factors for outcome. Traumatic brain injury continues to be a considerable problem and the increase in severe traumatic brain injury in the middle age and older age groups after a seemingly

  18. Reactive burn models and ignition & growth concept

    Science.gov (United States)

    Menikoff, R.; Shaw, M. S.

    Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature). This leads to the Ignition & Growth concept, introduced by LeeTarver in 1980, as the basis for reactive burn models. A homo- genized burn rate needs to account for three meso-scale physical effects: (i) the density of active hot spots or burn centers; (ii) the growth of the burn fronts triggered by the burn centers; (iii) a geometric factor that accounts for the overlap of deflagration wavelets from adjacent burn centers. These effects can be combined and the burn model defined by specifying the reaction progress variable λ = g(s) as a function of a dimensionless reaction length s(t) = rbc/ℓbc, rather than by specifying an explicit burn rate. The length scale ℓbc(Ps) = [Nbc(Ps)]-1/3 is the average distance between burn centers, where Nbc is the number density of burn centers activated by the lead shock. The reaction length rbc(t) = ∫t0 D(P(t'))dt' is the distance the burn front propagates from a single burn center, where D(P) is the deflagration speed as a function of the local pressure and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. We have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

    Most literature about geriatric burns has focused on inpatient management; therefore, our study investigated the effects of burn characteristics and preexisting medical comorbidities on treatment outcomes for geriatric burn patients treated as outpatients. A retrospective review was conducted for 391 patients over 65 years of age seen in the emergency department of Fukui Prefectural Hospital over a 10-year period. Charts were reviewed for age, sex, burn characteristics, burn mechanisms, preexisting medical comorbidities, and treatment outcomes. Multivariate regression analysis was used to examine the relationship between outcomes of outpatients and comorbidities, which were calculated by the Charlson comorbidity index. Seventy-three patients aged 65 years and older were treated as outpatients at Fukui Prefectural Hospital. The majority (80%) of these patients had burns on less than 5% of their total body surface area. Scald burns accounted for 63% of burn mechanisms, with burns to the lower extremities being the most frequent. The mean percentage of total burn surface area was 4% in the outpatient group and 28% for the inpatient group. The mean time to healing was 24.3 days in outpatients. Of the 73 outpatients, 17 (23%) showed delayed healing. Of these 17 patients, 3 patients experienced wound infection and 2 patients had documented hypertrophic scarring. Four patients ultimately underwent excision and grafting. The common preexisting medical comorbidities in the outpatient group were congestive heart failure and diabetic mellitus. There were no significant differences for medical comorbidities between outpatients and inpatients. The Charlson comorbidity index for outpatients with delayed healing was higher than that for those without delayed healing. The Charlson comorbidity index was associated with delayed healing of outpatients, but age or total burn surface area were not. The characteristics of geriatric burn outpatients were distinct from those of inpatients

    Burning mouth syndrome (BMS) is a chronic condition of burning of the tongue and oral mucosa. It is often accompanied with complaints of xerostomia, although it is unknown whether the dryness is a sensory change similar to the burning sensation or due to hyposalivation. To determine whether there is change in salivary flow rate, whole salivary flows were measured in BMS patients. A clinical ambispective study was conducted. Patients' clinical files were reviewed for stimulated and unstimulated whole salivary flow. Patients were divided into four groups based on diagnosis into Sjögren's syndrome (SS), BMS, BMS taking oral drying medications (BMS-med), and control (C). Whole stimulated (SF) and unstimulated flow (USF) measurements were collected and compared among groups. Data were analysed with ANOVA, Levene's test, Tukey's test and Games-Howell test. Twenty SS, 22 BMS, 24 BMS-med and 15 C were included in the study. SF was significantly lower in SS (0.59 ml ± 0.36) compared with BMS (1.56 ml ± 0.65, p dry mouth. This suggests that hyposalivation may play a role in causing dry mouth in BMS, which may respond to treatment with a sialogogue.

    Many wound management protocols have been developed to improve wound healing after burn with the primordial aim to restore the barrier function of the skin and also provide a better esthetic outcome. Autologous skin grafts remain the gold standard in the treatment of skin burn, but this treatment has its limitation especially for patients presenting limited donor sites due to extensive burn areas. Deep burn injuries also alter the integrity of skin-sensitive innervation and have an impact on patient's quality of life by compromising perceptions of touch, temperature, and pain. Thus, patients can suffer from long-term disabilities ranging from cutaneous sensibility loss to chronic pain. The cellular mechanisms involved in skin reinnervation following injury are not elucidated yet. Depending on the depth of the burn, nerve sprouting can occur from the wound bed or the surrounding healthy tissue, but somehow this process fails to provide correct reinnervation of the wound during scarring. In addition, several clinical observations indicate that damage to the peripheral nervous system influences wound healing, resulting in delayed wound healing or chronic wounds, underlining the role of innervation and neuromediators for normal cutaneous tissue repair development. Promising tissue engineering strategies, including the use of biomaterials, skin substitutes, and stem cells, could provide novel alternative treatments in wound healing and help in improving patient's sensory recovery.

    Forty-seven patients with traumatic olecranon bursitis were evaluated after a mean follow-up of 31 months (range 6 to 62 months). Twenty-two patients treated with bursal aspiration had delayed recovery and no complications of therapy. Twenty-five patients treated with intrabursal injection of 20 mg of triamcinolone hexacetonide had rapid recovery, usually within one week, but suffered complications such as infection (3 cases), skin atrophy (5 cases), and chronic local pain (7 cases). Since spontaneous resolution can be expected, a conservative approach is suggested in the treatment of traumatic olecranon bursitis. Images PMID:6696516

    Burn injury is a public health concern often associated with individual pain, emotional stress, prolonged hospitalizations, permanent disfigurement and family stress. In this paper we studied the avaliable data on burn injury among adolescents in Israel through a Medline search and found three relevant studies with data on this population. The incidence rate of burn injury was 0.46 per 1,000 children aged 5-14 years for Jews and 0.91 for Bedouin. Most of the burn injury in this age group was caused by hot liquids, followed by fire and chemical burns for both Jews and Bedouin, but electical burns occurred more often in Bedouins. Mortality was very low for the adolescent group. Prevention programs in schools since the 1980s have been found effective, but the public health focus should now be geared towards groups at risk.

    The immunosuppression induced by thermal injury renders the burned victim susceptible to infection. A mouse model was developed to examine the immunosuppression, which was possible to induce even at a minor thermal insult of 6% total body surface area. After induction of the burn (48 hr......) a depression of leukocytes in the peripheral blood was found of the burned mice. This depression was due to a reduction in the polymorphonuclear cells. The burned mice were not able to clear a Pseudomonas aeruginosa wound infection, since the infection spread to the blood as compared to mice only infected...... with P. aeruginosa subcutaneously. The burn model offers an opportunity to study infections under these conditions. The present model can also be used to examine new antibiotics and immune therapy. Our animal model resembling the clinical situation is useful in developing new treatments of burn wound...

    Full Text Available Burn care is a huge challenge in India, having the highest female mortality globally due to flame burns. Burns can happen anywhere, but are more common in the rural region, affecting the poor. Most common cause is flame burns, the culprit being kerosene and flammable flowing garments worn by the women. The infrastructure of healthcare network is good but there is a severe resource crunch. In order to bring a positive change, there will have to be more trained personnel willing to work in the rural areas. Strategies for prevention and training of burn team are discussed along with suggestions on making the career package attractive and satisfying. This will positively translate into improved outcomes in the burns managed in the rural region and quick transfer to appropriate facility for those requiring specialised attention.

    Intracompartmental sepsis (IS) is a rare complication in patients with burns. Intracompartmental sepsis presents in patients with inadequate perfusion of intracompartmental tissues and subsequent ischemic necrosis and infection. Contributing factors include high-volume resuscitation, delayed escharotomies, and previous bacteremia. We describe a case of massive burns from a gas explosion and the subsequent development of IS in our intensive care burn unit. The patient presented with a 75% total body surface area burn on admission, with 39% superficial, deep partial-thickness and 26% full-thickness burns. Intracompartmental sepsis was diagnosed 45 days after admission. Anterior compartment muscles, including the tibialis anterior, extensor hallucis longus, and extensor digitorum longus, were necrotic with relatively fair nerve and vascular structures. Intracompartmental sepsis is an overwhelming, infectious complication that appears late and can occur easily in patients with major burns. Early diagnosis and management are a must for improving outcomes.

    To investigate the incidence, clinical and microbiological characteristics, risk factors, and therapeutic outcome of infectious keratitis in patients with limbal stem cell deficiency (LSCD) related to Stevens-Johnson syndrome (SJS) and corneal chemical burn. Medical records of 90 eyes of 59 patients who were diagnosed with LSCD resulting from SJS (52 eyes of 29 patients) or corneal chemical burn (38 eyes of 30 patients) were reviewed. Infectious keratitis developed in 35% of LSCD patients with SJS (18 eyes, 14 patients) and in 18% of those with chemical burn (7 eyes, 7 patients). The development of infectious keratitis in SJS was significantly associated with the severity of chronic ocular surface complications in the cornea, conjunctiva, and eyelids and with the use of topical corticosteroids during the disease course. All cases of infectious keratitis following chemical burn occurred in patients with grade III or IV burn by Roper-Hall classification. Approximately 83% of culture-proven cases of infectious keratitis were bacterial infection, most of which (80%) were caused by Gram-positive bacteria. For resolution of infection, 17 eyes (68%) received surgery in addition to medical treatment, whereas 8 eyes (32%) received medical treatment alone. After infection resolution, the final visual acuity was decreased in 10 eyes (40%) compared with before infection. Infectious keratitis is a common complication of LSCD associated with SJS or severe chemical burn to the cornea. Despite medical and surgical treatments, the visual outcome is poor.

    Hand burns represent a unique challenge to the burns team due to the intricate structure and unrivalled functional importance of the hand. The initial assessment and prognosis relies on consideration of the specific site involved as well as depth of the burn. We created a simple severity score that could be used by referring non-specialists and researchers alike. The Hand Burn Severity (HABS) score stratifies hand burns according to severity with a numerical value of between 0 (no burn) and 18 (most severe) per hand. Three independent assessors scored the photographs of 121 burned hands of 106 adult and paediatric patients, demonstrating excellent inter-rater reliability (r=0.91, pburn depth alone. The HABS score is a simple to use tool to stratify severity at initial presentation of hand burns which will be useful when referring, and when reporting outcomes.

  18. High burn rate solid composite propellants

    Science.gov (United States)

    Manship, Timothy D.

    High burn rate propellants help maintain high levels of thrust without requiring complex, high surface area grain geometries. Utilizing high burn rate propellants allows for simplified grain geometries that not only make production of the grains easier, but the simplified grains tend to have better mechanical strength, which is important in missiles undergoing high-g accelerations. Additionally, high burn rate propellants allow for a higher volumetric loading which reduces the overall missile's size and weight. The purpose of this study is to present methods of achieving a high burn rate propellant and to develop a composite propellant formulation that burns at 1.5 inches per second at 1000 psia. In this study, several means of achieving a high burn rate propellant were presented. In addition, several candidate approaches were evaluated using the Kepner-Tregoe method with hydroxyl terminated polybutadiene (HTPB)-based propellants using burn rate modifiers and dicyclopentadiene (DCPD)-based propellants being selected for further evaluation. Propellants with varying levels of nano-aluminum, nano-iron oxide, FeBTA, and overall solids loading were produced using the HTPB binder and evaluated in order to determine the effect the various ingredients have on the burn rate and to find a formulation that provides the burn rate desired. Experiments were conducted to compare the burn rates of propellants using the binders HTPB and DCPD. The DCPD formulation matched that of the baseline HTPB mix. Finally, GAP-plasticized DCPD gumstock dogbones were attempted to be made for mechanical evaluation. Results from the study show that nano-additives have a substantial effect on propellant burn rate with nano-iron oxide having the largest influence. Of the formulations tested, the highest burn rate was a 84% solids loading mix using nano-aluminum nano-iron oxide, and ammonium perchlorate in a 3:1(20 micron: 200 micron) ratio which achieved a burn rate of 1.2 inches per second at 1000

    Tumors that develop in old burn scars are usually squamous cell carcinomas. Sarcomas have also been reported, albeit rarely. To our knowledge, there has been only one case report of an extraskeletal osteosarcoma arising in a prior burn scar reported in the English-language literature, mainly discussing the clinicopathological features. Herein, we present a case of cutaneous osteosarcoma visualized as a mineralized soft-tissue mass arising from the scar associated with a previous skin burn over the back. This seems to be the first report describing the imaging features of a cutaneous osteosarcoma from an old burn scar. (orig.)

    Those practicing Emergency Medicine are frequently faced with a patient presenting with a chemical burn. Most dermal chemical burns are minor and do not require specialized treatment. Occasionally, however, the clinician may be in the position of responding to a chemical burn in which standard therapy of irrigation and good wound care may not be sufficient or, at worst, contraindicated. Several burn conditions will be reviewed, some of those requiring only specific decontamination techniques, as in hot tar, others posing special hazards to clinicians, as in elemental metals, and finally, examples are given of hazardous materials requiring attention to systemic effects, as in hydrofluoric acid.
