RESUMO

Introduction: Traumatic brain injury (TBI) is an important public health concern and that may lead to severe neural sequels, such as color vision deficits. Methods: We evaluated the color vision of 10 TBI patients with normal cognitive function using a color discrimination test in a fixed saturation level. We also analyzed computerized tomography scans to identify the local of the brain damages. Results: Four TBI patients that had lesions in brain areas of the ventral visual streams, five TBI patients had lesions inferred in brain areas of the dorsal visual stream, and one TBI patient had lesion in the occipital area. All the patients had cognitive and color vision screened and they had characterized the chromatic discrimination at high and low saturation. All participants had no significant cognitive impairment in the moment of the color vision test. Additionally, they had perfect performance for discrimination of chromatic stimulus at high saturation and similar to controls (n = 37 age-matched participants). Three of four TBI patients with lesions in the ventral brain and one patient with lesion in the occipital area had impairment of the chromatic discrimination at low saturation. All TBI patients with lesions in the dorsal brain had performance similar or slightly worse than the controls. Conclusion: Chromatic discrimination at low saturation was associated to visual damage in the ventral region of the brain and is a potential tool for functional evaluation of brain damage in TBI patients.

RESUMO

Objetivo: Compreender o cotidiano de portadores de dor neuropática decorrente de lesão traumática. Metodologia: Pesquisa exploratória, descritiva, de abordagem qualitativa, com participantes selecionados por meio de mídias sociais. A coleta de dados foi realizada entre o período de julho a setembro de 2022, com indivíduos adultos que possuem diagnóstico de dor neuropática após lesão traumática. A coleta ocorreu por meio de um formulário online, utilizando um questionário sociodemográfico e um questionário aberto, para a captura de informações pertinentes sobre seu caso clínico e vivência com a dor crônica. Os dados foram analisados por meio de Bardin. Todos os preceitos éticos foram respeitados e o projeto foi aprovado sob parecer n.º 5.529.581 da Universidade Cesumar. Resultados: Participaram 15 pessoas com dor neuropática, com prevalência do sexo feminino (93,3%), com idade entre 41 a 50 anos (66,7%). Observou-se que 53,3% relataram comorbidades crônicas, sendo as doenças psíquicas, ansiolíticas e cardíacas mais citadas. Ainda, 33,3% dos participantes relataram que foram internados por causas de dores ou por tentativa de suicídio, 93,3% usam opióides e analgésicos potentes e ainda foram citados antidepressivos e ansiolíticos em 62% das respostas. Dentre os temas em destaque nas respostas, sobressaíram-se "Contexto e diagnóstico da dor neuropática; Vivência e frequência da dor; Apoio profissional e familiar diante da doença". Considerações Finais: Nesse sentido, a percepção acerca dos profissionais de saúde e valorização do médico para o tratamento da dor neuropática está relacionada, muitas vezes, à necessidade de aumentar o conhecimento referente ao manejo da dor e à utilização de opióides.

Objective: To understand the daily life of patients with neuropathic pain resulting from traumatic injury. Methodology: Exploratory, descriptive research, with a qualitative approach, with participants selected through social media. Data collection was carried out between July and September 2022, with adult individuals diagnosed with neuropathic pain after traumatic injury. The collection took place through an online form, using a sociodemographic questionnaire and an open questionnaire, to capture relevant information about their clinical case and experience with chronic pain. Data were analyzed using Bardin. All ethical precepts were respected and the project was approved by report n.º 5,529,581 of Cesumar University. Results: 15 people with neuropathic pain participated, with a prevalence of females (93.3%), aged between 41 and 50 years (66.7%). It was observed that 53.3% reported chronic comorbidities, with psychic, anxiolytic and cardiac diseases being the most cited. Also, 33.3% of the participants reported that they were hospitalized due to pain or a suicide attempt, 93.3% used opioids and potent analgesics, and antidepressants and anxiolytics were mentioned in 62% of the answers. Among the topics highlighted in the responses, the most important were "Context and diagnosis of neuropathic pain; Experience and frequency of pain; Professional and family support in the face of the disease". Final Considerations: In this sense, the perception of health professionals and the appreciation of physicians for the treatment of neuropathic pain is often related to the need to increase knowledge regarding pain management and the use of opioids.

RESUMO

Introduction Traumatic brain injury (TBI) is among the main causes of death and neurological sequelae worldwide. Injuries are classified as diffuse (diffuse axonal injury and brain swelling) or focal (cerebral contusion [CCo], epidural hematoma, and acute subdural hematoma). Among all TBIs, CCos are the most frequent focal lesion, and treatment modalities are many. Hematoma evacuation using large craniotomies has been well described in the literature. The main goal of the present study is to discuss the advantages of minimally invasive approaches for the treatment of CCos, regarding operative time, blood loss, and postoperative tomographic results. Methods An integrative literature review was conducted on the SciELO, LILACS, and PubMed databases. Seven case reports were included in the present study. Retrospective data collection was performed, analyzing gender, age, Glasgow coma scale score on hospital admission, surgical approach, and postoperative (tomographic) results. Results The minimally invasive keyhole approach was used in seven patients with CCos. The supraorbital approach (n » 5) was performed for frontal lobe contusions, and the minipterional approach (n » 2) was performed for temporal lobe contusions. All cases had adequate hematoma evacuation, confirmed by postoperative computed tomography scans. Conclusion The minimally invasive approaches were effective for hematoma evacuation, with adequate clinical and radiological postoperative results.

Introdução O traumatismo cranioencefálico se encontra entre as principais causas de óbito e sequelas neurológicas na estatística mundial. As lesões são classificadas como difusas (lesão axonal difusa e edema cerebral traumático) ou focais (contusões cerebrais [CoC], hematoma epidural, e hematoma subdural agudo). Dentre todos os tipos de lesões cerebrais traumáticas, as contusões são a lesão focal mais comum, e são reservadas a elas múltiplas modalidades de tratamento. O principal objetivo desse estudo é discutir as vantagens dos acessos minimamente invasivos no tratamento de contusões cerebrais, especialmente no que concerne à duração do procedimento, perda sanguínea e resultados tomográficos pós-operatórios. Métodos Uma revisão integrativa de literatura foi conduzida nas plataformas Scientific Electronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e PubMed. Sete relatos de caso foram incluídos neste estudo. A coleta retrospectiva de dados foi realizada com a análise das seguintes variáveis: gênero, idade, escala de coma de Glasgow à admissão, acesso cirúrgico utilizado e resultados tomográficos pós-operatórios. Resultados O acesso cirúrgico minimamente invasivo foi utilizado em sete pacientes com CoC. O acesso supraorbital (n » 5) foi usado para tratar contusões frontais, enquanto o acesso minipterional (n » 2) foi usado para o tratamento de contusões temporais. Em todos os casos, foi obtida drenagem satisfatória do hematoma, confirmada por meio de tomografias pós-operatórias. Conclusão Os acessos minimamente invasivos foram efetivos para evacuação dos hematomas intraparenquimatosos, com resultados clínicos e tomográficos favoráveis.

RESUMO

Traumatic subdural hemorrhage (TSH) is an injury between the meningeal membranes, caused by traumas, especially traffic accidents. OBJECTIVE: To describe the mortality rate (MR) due to TSH in the period 2018-2022 in Chile. MATERIALS AND METHODS: Descriptive, observational, and cross-sectional study on MR due to TSH in the period 2018-2022 in Chile, according to gender, age group, regional distribution, place of death, and month of death. Anonymous and public databases were used. No ethics committee approval was required. RESULTS: The average MR due to TSH in Chile from 2018 to 2022 was 0.45/100,000 inhabitants, with a peak in 2018 (0.75) and a minimum in 2021 (0.31). Men had higher rates. Mortality increased with age, especially in those over 80 years. The Metropolitan Region accounted for 35.2% of TSH-related deaths. Hospitals and clinics were the main places of death (67.1%), with more deaths in March, July, and August. DISCUSSION: The MR due to TSH progressively decreased due to medical improvements. Men have higher rates, possibly due to risk factors or biological differences. The reduction in MR in hospitals is linked to changes in the severity and categorization of the place of death. The connection with traffic accidents is significant, especially between March and August, due to the return to academic activities and weather conditions. Additionally, TSH-related deaths are concentrated in densely populated regions with more traffic accidents.

RESUMO

INTRODUCTION: Traumatic brain injury (TBI), a leading cause of morbidity and mortality among trauma patients worldwide, poses the risk of secondary neurological insult due to significant catecholamine surge. We aim to investigate the effectiveness and outcomes of beta-blocker administration in patients with severe TBI. METHODS: A search through PubMed, EMBASE, JAMA network, and Google Scholar databases was conducted for relevant peer-reviewed original studies published before February 15, 2022. A standard random-effects model was used, as justified by a high Cohen's Q test. RESULTS: Twelve studies met inclusion criteria and were included in the meta-analysis. Severe TBI patients who were administered beta-blockers had a significantly reduced incidence of in-hospital mortality compared to the non-beta-blocker group (14.5% vs 19.2%). However, the beta-blocker group was reported to have a significantly greater number of ventilator days (5.58 vs 2.60 days). Similarly, intensive care unit (9.00 vs 6.84 days) and hospital (17.30 vs 11.02 days) lengths of stay (LOS) were increased in the beta-blocker group compared to those who were not administered beta-blocker therapy, but only the difference in hospital-LOS was significant. CONCLUSIONS: Beta-blockers have significantly decreased in-hospital mortality in patients with severe TBI despite being associated with an increase in ventilator days and hospital-LOS. The administration of beta-blocker therapy in the management of severe TBI may be warranted and should be discussed in future guidelines.

RESUMO

The brain-lung interaction can seriously affect patients with traumatic brain injury, triggering a vicious cycle that worsens patient prognosis. Although the mechanisms of the interaction are not fully elucidated, several hypotheses, notably the "blast injury" theory or "double hit" model, have been proposed and constitute the basis of its development and progression. The brain and lungs strongly interact via complex pathways from the brain to the lungs but also from the lungs to the brain. The main pulmonary disorders that occur after brain injuries are neurogenic pulmonary edema, acute respiratory distress syndrome, and ventilator-associated pneumonia, and the principal brain disorders after lung injuries include brain hypoxia and intracranial hypertension. All of these conditions are key considerations for management therapies after traumatic brain injury and need exceptional case-by-case monitoring to avoid neurological or pulmonary complications. This review aims to describe the history, pathophysiology, risk factors, characteristics, and complications of brain-lung and lung-brain interactions and the impact of different old and recent modalities of treatment in the context of traumatic brain injury.

RESUMO

Background: Traumatic brain injuries (TBI) are a leading cause of death and disability worldwide. Violence is the leading cause of mortality in Honduras. However, the incidence and impact of TBI in this low-middle income country (LMIC) is unknown. The aim of this study is to describe the epidemiology of TBI in Honduras, as captured by an injury surveillance tool in the country's major referral center. Methods: A cross sectional review of all TBI-related emergency department visits at the main referral hospital in Honduras from January to December 2013 was conducted. The calculation of descriptive statistics from Injury Surveillance System (InSS) data was performed. Results: Of 17,971 total injuries seen in 2013, 20% were traumatic brain injuries (n=3,588). The main mechanisms of injury were falls (41.11%), road traffic accidents (23.91%), blunt trauma (20.82%), penetrating knife injuries (5.85%), and firearm injuries (2.26%). Most TBI were classified as mild; 99.69% (Glasgow Coma Scale=15). Emergency room mortality was low (1.11%). The modified Kampala Trauma Score median was 8 (interquartile range 7-8). Conclusion: Mild TBI accounts for a significant percentage of all injuries presenting to a high-volume referral center in Honduras in 2013. Despite the high incidence of violence in this country, most TBI were accidental, secondary to road traffic accidents and falls. Further research is required with more recent data as well as with prospective data collection methods.

RESUMO

Objective A frequent challenge for the neurosurgeon when treating a patient with cranioencephalic trauma is to determine whether the patient has a vascular lesion, when to suspect it, and what studies to request. In this context, the objective of the present study was to identify the variables on cranial computed tomography (CT) scans that predict vascular injury in digital subtraction angiography in patients with cranioencephalic trauma. ethods We conducted a cross-sectional study of patients with cranioencephalic trauma admitted to the Hospital Universitario del Valle between June 2016 and June 2019. Subjects with available simple CT images of the skull and digital subtraction angiography were included. Results A total of 138 subjects who met the inclusion criteria were identified. The average age was 32 years, 82% were men, and the most frequent mechanism of injury was firearm wound (59%). The variables associated with vascular injury were fracture of the base of the temporal skull and sphenoid fracture. Conclusion The presence of fractures of the base of the temporal skull and sphenoid fractures is associated with vascular injury in patients with cranioencephalic trauma.

Objetivo Um desafio frequente para o neurocirurgião no cuidado de um paciente com traumatismo crânio-encefálico é determinar se o paciente tem lesão vascular, quando suspeitar que tem, e quais estudos pedir. Neste contexto, o objetivo deste estudo foi identificar as variáveis da tomografia computadorizada (TC) de crânio que predizem lesão vascular na angiografia por subtração digital em pacientes com traumatismo crânio-encefálico. Métodos Fez-se um estudo transversal de pacientes com traumatismo crânio-encefálico internados no hospital (cego) entre junho de 2016 e junho de 2019. Foram incluídos também pacientes com imagens de TC simples do crânio e angiografia de subtração digital disponíveis. Resultados Foram identificados um total de 138 sujeitos que cumpriam os critérios de inclusão. A média de idade foi de 32 anos, 82% eram homens, e o mecanismo da lesão mais frequente foi o ferimento por arma de fogo (59%). As variáveis associadas à lesão vascular foram a fratura da base do crânio temporal e a fratura esfenoidal. Conclusão A presença de fraturas da base do crânio temporal e fraturas do esfenoide está associada à lesão vascular em pacientes com traumatismo crânio-encefálico.

RESUMO

Chronic traumatic encephalopathy (CTE) is a neurodegenerative syndrome caused by repetitive and cumulative head trauma. Due to the widespread practice of contact and collision sports, a discussion of the long-term repercussions of repeated head trauma is imperative. The present literature review, performed through the SciELO, PUBMED, and BVS-Bireme databases, includes studies conducted since the year 2000, which established the relationship between CTE and the practice of sports. The diagnosis of CTE was notably present in individuals practicing sports that involve repeated traumatic brain injuries. The noticeable changes triggered by CTE include a series of clinical and neuropathological manifestations that can help in the differentiation from other tauopathies.

A encefalopatia traumática crônica (ETC) é uma síndrome neurodegenerativa causada por traumatismo craniano repetitivo e cumulativo. Com a prática disseminada de esportes de contato, torna-se importante discutir as repercussões a longo prazo de traumatismos cranianos repetidos. A presente revisão da literatura, executada através das bases de dados SciELO, PUBMED e BVS-Bireme, inclui estudos realizados desde o ano de 2000 que estabeleceram a relação entre a ETC e a prática de esportes. O diagnóstico de ETC esteve notadamente presente em indivíduos praticantes de esportes que envolvem repetidas lesões cerebrais traumáticas. As alterações perceptíveis desencadeadas pela ETC incluem uma série de manifestações clínicas e neuropatológicas, que podem auxiliar na diferenciação de outras tauopatias.

RESUMO

BACKGROUND: Cerebellar mutism (CM) is defined as the lack of speech production, despite an intact state of consciousness and cognitive function, that happens secondary to a cerebellar insult. To the best of our knowledge, only five cases have thus far been described in the English literature. In this paper, we report the sixth incidence overall, which is also the first case of a CM associated with penetrating head injury. The relevant literature is reviewed and analyzed, our current knowledge of the neuroanatomical and functional relations is summarized, and potential future research endeavors are indicated. CASE DESCRIPTION: An 8-year-old girl was transferred to our hospital having had fallen on a rod that penetrated her neck behind the ear. An urgent computed tomography scan of the head revealed a right cerebellar contusion with surrounding edema. Three days later, she became mute but was still obeying commands. Repeat imaging showed a resolving cerebellar contusion with increased edema and mass effect. By day 9, she had uttered a few words. At 1-month follow-up, the child had regained normal speech. CONCLUSION: Posttraumatic CM is a rare and probably underreported condition with only six documented cases to date. Although it may well be on the same spectrum as postoperative CM, further understanding of the exact mechanism, clinical course, and prognosis of this entity is bound to significantly improve the recovery and quality of life of head trauma patients.

Materiales y métodos: Estudio observacional, prospectivo, analítico. Se identificaron las consultas por traumatismo encefalocraneano leve entre el 30 de julio de 2018 y el 15 de agosto del 2019. Se valoró la presencia de factores de riesgo para lesión como escala de coma de Glasgow al ingreso y a las 2 horas, cinemática del trauma, sospecha de fractura de base y bóveda de cráneo, cefalea, vómitos, mayores a 65 años, pérdida de conocimiento, amnesia del episodio, anticoagulación o antiagregación y consumo de alcohol o drogas. Se consignaron los casos con tomografías patológicas y necesidad de neurocirugía. Resultados: Se incluyeron 1319 pacientes, 9% de estudios patológicos y 1,2% requirieron neurocirugía. Resultaron significativas como factores de riesgo la alta cinemática del traumatismo (p 0,02); escala de coma de Glasgow a las 2 horas (p 0,014); sospecha de fractura de bóveda (p 0,003) y base de cráneo (p 0,000); vómitos en más de dos ocasiones (p 0,000); cefalea (p 0,01) y amnesia del episodio (p 0,012) Conclusiones: La identificación de factores predictivos de lesión ayuda a optimizar el uso de tiempo del tomógrafo suprimiendo estudios innecesarios y priorizando los potencialmente patológicos.

Abstract: Introduction: The systematic performance of skull tomography in mild brain trauma is controversial, corresponding to 70-90% of cases. Up to 10% of these traumas will present injuries and 1.4% will require neurosurgery. The objective of the study is to determine the number of pathological scans in mild head injury and to identify predictive factors for injury. Materials and methods: Observational, prospective, analytical study. Consultations for mild brain injury were identified between July 30, 2018 and August 15, 2019. The presence of risk factors for injury was assessed as the Glasgow coma scale at admission and at 2 hours, trauma kinematics, suspicion of skull base and vault fracture, headache, vomiting, people over 65 years of age, loss of consciousness, amnesia of the episode, anticoagulation or antiplatelet therapy and alcohol or drug use. The cases with pathological tomography and the need for neurosurgery were consigned. Results: 1,319 patients were included, 9% of pathological studies and 1.2% required neurosurgery. The high kinematics of trauma were significant as risk factors (p 0.02); Glasgow coma scale at 2 hours (p 0.014); suspicion of fracture of the vault (p 0.003) and skull base (p 0.000); vomiting on more than two occasions (p 0.000); headache (p 0.01) and episode amnesia (p 0.012). Conclusions: The identification of predictive factors of injury helps to optimize the use of tomography time by eliminating unnecessary studies and prioritizing potentially pathological ones.

Resumo: Introdução: O desempenho sistemático da tomografia de crânio no trauma cerebral leve é ​​controverso, correspondendo a 70-90% dos casos. Até 10% desses traumas apresentarão lesões e 1,4% necessitarão de neurocirurgia. O objetivo do estudo é determinar o número de exames patológicos em traumatismo craniano leve e identificar fatores preditivos de lesão. Materiais e métodos: Estudo observacional, prospectivo e analítico. As consultas para lesão cerebral leve foram identificadas entre 30 de julho de 2018 e 15 de agosto de 2019. A presença de fatores de risco para lesão foi avaliada pela escala de coma de Glasgow na admissão e em 2 horas, cinemática do trauma, suspeita de fratura da base do crânio e abóbada, dor de cabeça, vômitos, pessoas com mais de 65 anos, perda de consciência, amnésia do episódio, anticoagulação ou terapia antiplaquetária e uso de álcool ou drogas. Os casos com tomografia patológica e necessidade de neurocirurgia foram dispensados. Resultados: 1.319 pacientes foram incluídos, 9% dos estudos patológicos e 1,2% neurocirurgia necessária. A alta cinemática do trauma foi significativa como fator de risco (p 0,02); Escala de coma de Glasgow em 2 horas (p 0,014); suspeita de fratura de abóbada (p 0,003) e base do crânio (p 0,000); vômito em mais de duas ocasiões (p 0,000); dor de cabeça (p 0,01) e episódio de amnésia (p 0,012). Conclusões: A identificação de fatores preditivos de lesão auxilia na otimização do uso do tempo de tomografia, eliminando estudos desnecessários e priorizando os potencialmente patológicos.

RESUMO

BACKGROUND: Aneurysms in the pediatric population are uncommon, requiring a high index of suspicion for diagnosis. We report a case of a child with head trauma and delayed diagnosed cerebral aneurysm. METHODS: A 2-year-old girl was brought to the emergency room with seizures. Head imaging showed acute intraventricular hemorrhage, hydrocephalus, and paraclinoid aneurysm of the right internal carotid artery. She had been hospitalized elsewhere 1 month prior for traumatic brain injury after falling to the ground with subarachnoid and intraventricular hemorrhage and good recovery, but without diagnosis of aneurysm. RESULTS: The child was treated with aneurysm embolization and ventriculoperitoneal shunt, being discharged asymptomatic. CONCLUSION: Most primary intraventricular hemorrhage in pediatric population has identifiable etiology. A high rate of clinical suspicion, associated with a low threshold for vascular neuroimaging studies for children with spontaneous or atypical intracranial hemorrhage allow accurate diagnosis, appropriate treatment, and improved outcome.

RESUMO

CONTEXT: Concussions are a global public health concern, and education on the importance of self-reporting may not reach all athletes to the same degree around the world. OBJECTIVE: To determine if differences were present in the concussion awareness, understanding, and -reporting behaviors of collegiate athletes' in 3 countries with varied degrees of concussion publicity. DESIGN: Cross-sectional survey. SETTING: Collegiate sports medicine clinics. PATIENTS OR OTHER PARTICIPANTS: Collegiate athletes in the United States (n = 964; high publicity), Ireland (n = 302; moderate publicity), and Jordan (n = 129; low publicity). The degree of concussion publicity was categorized based on the extent of national public health awareness initiatives, care guidelines, research publications, and mass media coverage. MAIN OUTCOME MEASURE(S): Participants completed a 10- to 15-minute survey on concussion awareness, understanding, and -reporting behaviors. The main outcome measures were concussion education (awareness; 21 options; select all sources of concussion information), concussion knowledge (understanding; maximum score of 49), and diagnosed/nondisclosed concussion history (reporting behaviors; self-report yes/no items). RESULTS: A higher proportion of Jordanian athletes reported never having received concussion information previously (73.6%) than Irish (24.2%) or US athletes (9.4%). Knowledge differed among countries (P < .0001, η2 = .28), with US athletes displaying higher total knowledge scores (40.9 ± 4.5) than Jordanian (35.1 ± 5.6) and Irish (32.1 ± 3.5) athletes. Greater percentages of Irish and US athletes reported a history of a diagnosed concussion (31.8% and 29.6%, respectively) and history of concussion nondisclosure (25.2% and 15.5%, respectively) than Jordanian athletes (2.3% and 0.0% for history of a diagnosed concussion and history of concussion nondisclosure, respectively). CONCLUSIONS: In the United States, where concussion publicity is high, formal legislation exists, and sports medicine resources and concussion awareness and understanding were increased. More culturally appropriate concussion initiatives are needed globally to ensure that athletes around the world can identify concussive injuries and understand the dangers of continued sport participation while concussed.

RESUMO

ABSTRACT Objective: to evaluate the clinical-epidemiological characteristics, treatment, and evolution of patients with occipital condyle fracture (OCF) at one of the largest referral trauma centers in Latin America. Methods: this was a retrospective observational study of OCF identified from trauma cases admitted between December 2011 and December 2019 by the neurosurgery team at a Type 3 trauma center. Results: a total of twenty-eight occipital condyle fractures were identified in twenty-six patients. The incidence was less than 0.2% per year and more common in male patients (4:1 ratio) involved in traffic accidents. The mean age was 42.08 years. Anderson and Montesano type II and Tuli type 1 were the most frequent (67.9% and 89.3%, respectively) and no case presented C0-C1-C2 instability. All patients were treated with a cervical collar for 3 to 6 months. About 65% of the patients exhibited good progression (Glasgow Outcome Scale equal to 4), and the severity of traumatic brain injury was the main determinant for negative outcomes. Conclusion: the findings of this study are in accordance with available literature data. The use of external stabilization with a cervical collar is reinforced for the treatment of stable lesions, even when these are bilateral. Assessment of the patients' follow-up results in the studied sample may contribute with useful information for the treatment of occipital condyle fractures.

RESUMO Objetivo: avaliar o perfil clínico-epidemiológico, o tratamento e a evolução de pacientes com fraturas do côndilo occipital (FCO) em um dos maiores centros especializados em trauma na América Latina. Método: este é um estudo observacional retrospectivo de FCO identificadas em casos de trauma que foram atendidos no período de Dezembro de 2011 a Dezembro de 2019 pela equipe de trauma de centro de trauma Tipo 3. Resultados: um total de vinte e oito fraturas do côndilo occipital foram identificadas em 26 pacientes. A incidência foi inferior a 0.2% ao ano e mais comum em pacientes do sexo masculino (proporção 4:1) envolvidos em acidentes de trânsito. A idade média foi de 42.08 anos. O Tipo II de Anderson e Montesano e o Tipo 1 de Tuli foram os mais frequentes (67.9% e 89.3%, respectivamente) e nenhum caso teve instabilidades C0C1C2. Todos os pacientes foram tratados com colar cervical por período de 3 a 6 meses. Cerca de 65% dos pacientes apresentaram boa evolução (Escala de Resultados de Glasgow maior ou igual a 4), e a gravidade da lesão cerebral foi o principal determinante para os resultados negativos. Conclusão: os achados deste estudo são similares a dados disponíveis na literatura. O uso de colar cervical para estabilização externa é reforçado para o tratamento de lesões estáveis, mesmo quando bilaterais. A avaliação dos resultados do acompanhamento dos pacientes na amostra estudada pode contribuir com informações úteis para o tratamento de fraturas de côndilo occipital.

RESUMO

OBJECTIVES: To investigate the molecular mechanism of edaravone (EDA) in improving the post-traumatic brain injury (TBI) dysfunction in learning and memory. METHODS: In vitro and in vivo TBI models were established using hydrogen peroxide (H2O2) treatment for hippocampal nerve stem cells (NSCs) and surgery for rats, followed by EDA treatment. WST 1 measurement, methylthiazol tetrazolium assay, and flow cytometry were performed to determine the activity, proliferation, and apoptosis of NSCs, and malondialdehyde (MDA), lactic dehydrogenase (LDH), and reactive oxygen species (ROS) detection kits were used to analyze the oxides in NSCs. RESULTS: Following EDA pretreatment, NSCs presented with promising resistance to H2O2-induced oxidative stress, whereas NSCs manifested significant increases in activity and proliferation and a decrease in apoptosis. Meanwhile, for NSCs, EDA pretreatment reduced the levels of MDA, LDH, and ROS, with a significant upregulation of Nrf2/antioxidant response element (ARE) signaling pathway, whereas for EDA-treated TBI rats, a significant reduction was observed in the trauma area and injury to the hippocampus, with improvement in memory and learning performance and upregulation of Nrf2/ARE signaling pathway. CONCLUSIONS: EDA, by regulating the activity of Nrf2/ARE signal pathway, can improve the TBI-induced injury to NSCs and learning and memory dysfunction in rats.

RESUMO

Background: Paroxysmal autonomic instability with dystonia (PAID) syndrome, a subset of dysautonomia, is characterized by paroxysms of marked agitation, diaphoresis, hyperthermia, hypertension, tachycardia and tachypnea accompanied by hypertonia and extensor posturing. Case Report: We report a 52-year-old man who was severely brain injured and developed spastic tetraparesis with cognitive impairment. During his Intensive care unit stay and rehabilitation period, he presented with paroxysmal episodes of dystonic posturing accompanied by dysautonomia. Discussion: Our case raises awareness of PAID, a life-threatening condition which can mimic many others and poses significant challenges in the acute management and rehabilitation of patients. Highlights: PAID is characterized by paroxysms of marked agitation, diaphoresis, hyperthermia, hypertension, tachycardia and tachypnea accompanied by hypertonia and extensor posturing.It usually presents in patients with severe brain injury primarily due to trauma or hypoxia resulting in diffuse axonal or brainstem injury.PAID is also associated with tuberculous meningitis, interpeduncular tuberculoma, pneumococcal meningoencephalitis, intracerebral hemorrhage and paraneoplastic limbic encephalopathy.Differential diagnosis of PAID include neuroleptic malignant syndrome, malignant hyperthermia, sepsis, thyroid storm, pheochromocytoma, autonomic epileptic seizures, sepsis and impending cerebral herniation.
