ABSTRACT

Resumen Los accidentes de tránsito son una de las principales causas de lesiones y muertes en la población general, se ha descrito que aproximadamente el 60% de las muertes por accidentes de tránsito son ocasionadas por el trauma craneoencefálico, siendo que el daño axonal difuso es una causa frecuente de coma y discapacidad grave. Dentro de los hallazgos más importantes en la autopsia médico legal a nivel macróscopico se encuentran las petequias en cuerpo calloso, hemorragias en sustancia blanca, entre otros y a nivel microscópico se observan edema axonal reactivo diseminado. En el presente artículo se comentará un caso de daño axonal difuso secundario a un accidente de tránsito, además se realizará una revisión del tema abarcando los puntos más importantes a tomar en cuenta desde el punto de vista médico legal.


Abstract Traffic accidents are one of the main causes of injuries and deaths in the general population, it has been described that approximately 60% of deaths from traffic accidents are caused by head trauma, diffuse axonal damage is a cause frequent coma and severe disability after head trauma, among the most important findings in the legal medical autopsy at the macroscopic level are the petechiae in the corpus callosum, hemorrhages in white matter, among others and at the microscopic level disseminated reactive axonal swelling. In this article, a case of diffuse axonal damage secondary to a traffic accident will be discussed, and a review of the subject will be carried out covering the most important points to be taken into account from the legal medical point of view.

ABSTRACT

ABSTRACT: Cranioencephalic trauma (CET) is defined is the combination of neural and vascular injuries and their inflammatory effects in the brain, skull and scalp. This modality of trauma may lead to motor, psychological and cognitive sequels or even death. The present study aimed to assess the main epidemiological aspects in victims of CET treated at Cuiabá Municipal Hospital (CMH), Brazil. An observational and analytical study was performed in the medical records of patients diagnosed with CET treated at CMH between July and December of 2000, 2006 and 2011. The information retrieved from the patients consisted of age, sex, place of residence, cause of trauma, association with other trauma, outcomes (death or discharge) and the severity of neurological effect (Glasgow Coma Scale). The data obtained was analyzed descriptively with absolute (n) and relative (%) quantification. Medical records of 669 victims were analyzed, out of which 567 were males (84.7 %). Male patients were aged between 20 and 39 years old (mean age: 32.8 years). The most prevalent cause of trauma was the motorcycle accident (26.6 %). The neurological severity of the CET was mild in most of the cases (32.5 %). Considering the place of residence, most of the patients (n=331; 49.5 %) were from the capital city of Mato Grosso State (Cuiabá, Brazil). Four-hundred seventy-nine (71.6 %) patients progressed without death. A high prevalence rate of CET was observed at CMH. Major attention must be given to young adult victims of motorcycle accidents.


RESUMEN: El traumatismo craneoencefálico (TCE) se define como una combinación de daño neural, insuficiencia vascular y efectos inflamatorios que comprometen el cráneo, el encéfalo y el cuero cabelludo, causando la muerte, o serias secuelas motoras, psicológicas y cognitivas. De esta forma, el objetivo de este trabajo fue evaluar los principales aspectos epidemiológicos en victimas de Traumatismo Craneoencefálico (TCE) atendidas en el Hospital y Sala de Primeros Auxilios Municipal de Cuiabá (HPSMC), Brasil. Se trata de un estudio observacional de historias clínicas del archivo del HPSMC, admitidos con diagnóstico de TCE en el período de julio a diciembre de los años 2000, 2006 y 2011. Se consideraron el rango de edad, el sexo, la procedencia de las víctimas, la causa del trauma, la asociación con otros traumas, la defunción y el alta, el cuadro neurológico (Escala de Coma de Glasgow - ECG). El análisis de los datos fue descriptivo con números absolutos y porcentajes. Se evaluaron historias clínicas de 669 víctimas de TCE, en los que el sexo masculino fue el de mayor prevalencia con 567 casos (84,7 %), con mayor incidencia en el rango de edad de 20 a 39 años (39,2 %), el promedio de edad fue de 32,8 años, siendo la etiología más frecuente los accidentes motociclísticos (26,6 %). En el momento de la admisión de acuerdo al ECG hubo una predominancia de TCE leve (32,5 %). En cuanto a la procedencia, 331 (49,5 %) eran del municipio de Cuiabá. Del total de víctimas, 479 (71,6 %) evolucionaron hasta tener el alta hospitalaria. Se registró una prevalencia elevada de TCE en el HPSMC, con predominancia de víctimas adultas jóvenes de sexo masculino, siendo los accidentes motociclísticos la principal causa.

ABSTRACT

Introduction:This study describes the demographics, aetiology, emergency centre diagnosis and severity indicators of patients with head injuries presenting to the largest referral hospital emergency centre in Botswana.Methods:Cross-sectional retrospective data was collected from July 2015 to September 2015 for all emergency centre head injury presentations at Princess Marina Hospital. Information was extracted from emergency centre records regarding patient demographics, mechanism of injury, clinical observations, diagnosis, and treatment.Results:Three-hundred and sixty head injury patients presented to the emergency centre in the three months, averaging four per day. 80% were less than 40 years of age and males accounted for 69% of all presentations. 58% of injuries were listed as being accidental, 39% recorded from assaults and 38% from road traffic accidents. The most common emergency centre clinical diagnosis was concussion and the most common radiological diagnosis skull fracture. The median Glasgow Coma Scale was 15 with a range from 3 to 15; and, among patients for whom Revised Trauma Score could be calculated, 79% scored the lowest probability of death in the Revised Trauma Score.Discussion:Head injury disproportionately overburdened males in this study, and head injury aetiology and demographic picture was similar to regional data. Severity scoring using the Glasgow Coma Scale was only available among 66% of patients and Revised Trauma Score calculable in half of presentations. Only 55% of head injury patients were discharged from the emergency centre, despite the preponderance of low severity scores. Head CTs appear to have been over-utilised and implementation of a Traumatic Head CT guideline for our setting is proposed. This study improves understanding of the burden of head injury in Botswana and advocates for national referral guidelines for patients with head injury in Botswana

ABSTRACT

RESUMO Estudo retrospectivo, transversal e descritivo, aprovado pelo Comitê de Ética em Pesquisa (CEP), sob o número CAAE 16728013.0.0000.5346. Trata-se de uma série de casos que tem por objetivo investigar a presença de sintomas otoneurológicos e o equilíbrio postural de seis pacientes com tontura após traumatismo cranioencefálico (TCE). Foram submetidos a uma anamnese clínica e a avaliações: teste de organização sensorial por meio da posturografia dinâmica foam laser e provas oculomotoras e vestibulares da vectoeletronistagmografia computadorizada (VENG). Os dados foram analisados a partir dos valores de referência para cada avaliação. Na posturografia, observou-se que as maiores diferenças entre o valor obtido e o valor de referência foram nas posições VI, V e III, respectivamente. A análise sensorial indicou alteração, principalmente, nos sistemas de preferência visual e vestibular. Todos os pacientes avaliados apresentaram ao menos uma alteração nas provas da VENG. Cinco pacientes tiveram alteração na prova calórica e nenhum apresentou alteração na prova rotatória pendular decrescente, que avalia a compensação vestibular. Além das queixas vestibulares, quatro pacientes estavam em tratamento com psicotrópicos para depressão. Tais resultados ratificam a presença de alterações vestíbulo-oculares no pós-TCE, os quais devem receber atenção especial devido ao comprometimento central associado.


ABSTRACT It is a retrospective, cross-sectional, descriptive, approved by Ethics Research Committee (ERC), under number CAAE 16728013.0.0000.5346. This is a series of cases that aims to investigate the presence of otoneurological symptoms and the postural balance of six patients with dizziness after Traumatic Brain Injury (TBI). Participants were submitted to a clinical anamnesis and the evaluations: Sensory Organization Test through Foam Laser Dynamic Posturography and oculomotor and vestibular tests of Computerized Vectoelectronystamography (VENG). The data were analyzed from the reference values for each evaluation. In posturography, it was observed that the greatest differences between the value obtained and the reference value were in positions VI, V and III, respectively. Sensory analysis indicated alteration mainly in the visual and vestibular preference systems. All the evaluated patients presented at least one alteration in the VENG tests. Five patients had alterations in the caloric test, and none presented alterations to the rotatory chair test (RCT), which evaluates the vestibular compensation. Considering vestibular complaints, four patients were on psychotropic treatment for depression. These results demonstrate the presence of vestibulo-ocular alterations in post-TBI, which should receive special attention due to associated central impairment.

ABSTRACT

Introduction. Le but de cette étude était d'évaluer les conditions de prise en charge des traumatismes crâniens de l'enfant au Centre Hospitalier Universitaire (CHU) de Brazzaville. Méthodologie. Nous avons revu les dossiers des enfants âgés d'un mois à 17 ans, hospitalisés dans le service de chirurgie polyvalente du CHU de Brazzaville entre janvier 2014 et décembre 2015, et avons retenu ceux qui l'étaient pour un traumatisme crânien. Les paramètres épidémiologiques, diagnostiques, thérapeutiques et évolutifs ont été analysés. Résultats. sur 66 enfant hospitalisés, 48 (72,72%) ont été admis pour un traumatisme crânien et parmi eux 45 (68,18%) enfants ont été inclus dont 33 garçons et 12 filles. Leur âge moyen était de 9,73 ans. Le traumatisme était consécutif à un accident de la voie publique dans 36 cas (80%), à une chute dans 6 cas (13,33%), et à une agression dans 3 cas (6,66%). Le score de Glasgow était inférieur ou égal à huit dans 12 cas (26,66%), compris entre 9 et 12 dans 25 cas (55,55%) et entre 13 et 15 dans 8 cas (17,77%). Le scanner crânio-encéphalique était réalisé en moyenne quatre jours après le traumatisme. Quatre enfants (8,88%) ont été opérés. L'évolution après 12 mois était favorable pour 26 enfants (78,79%) et 12 enfants ont été perdus de vue. Conclusion. la fréquence élevée des traumatismes crâniens chez l'enfant est liée aux accidents de la voie publique. Une prise en charge adéquate nécessite la disponibilité d'un scanner cranioencéphalique en urgence. Nous préconisons un renforcement de l'éducation et la communication s'agissant les accidents de la voie publique et la facilitation de l'accès à l'imagerie

ABSTRACT

O objetivo deste estudo foi utilizar a sonda uretral flexível como método alternativo para aferição da pressão intracraniana em coelhos com trauma cranioencefálico induzido pelo cateter de Fogarty 4 Fr (balão epidural) e comparar os dados obtidos com o método convencional de cateter de ventriculostomia. Foram utilizados 12 coelhos, machos, adultos, distribuídos aleatoriamente em dois grupos, denominados de G1: mensuração da PIC com cateter de ventriculostomia (n=6) e G2: mensuração com sonda uretral (n=6). Foram realizadas duas craniotomias na região parietal direita e esquerda para a implantação do cateter de ventriculostomia ou sonda uretral flexível e o balão epidural, respectivamente. A PAM, a PPC, a FC, a FR e a TR foram mensurados antes e após a craniotomia. A PIC foi avaliada após a craniotomia e a cada 10 minutos depois do preenchimento do balonete com 0,3mL de NaCl 0,9%, durante 40 minutos, e com 0,6mL, pelo mesmo período de tempo, totalizando 80 minutos. A PIC aumentou em ambos os grupos, sendo menores os valores registrados com a sonda uretral flexível. Foi possível reproduzir o aumento da PIC com o modelo experimental de TCE utilizando o cateter de Fogarty 4 Fr na região epidural e, embora haja a necessidade de outros estudos, a sonda uretral flexível demonstra ser um método alternativo de mensuração da PIC em coelhos com trauma cranioencefálico.(AU)


The aim of this study was to evaluate the use of flexible urethral catheter as an alternative method for measuring intracranial pressure in rabbits with head trauma induced by 4 F Fogarty catheter (epidural balloon) and compare the data obtained with the conventional method of ventriculostomy catheter. In this study, New Zealand rabbits were randomly distributed into two groups, G1: measuring the ICP with ventriculostomy catheter (n=6) and G2: measuring the ICP with urethral catheter (n=6). Two craniotomies were performed in the right and left parietal region for the implantation of a ventriculostomy catheter and/or flexible urethral catheter and epidural 4 Fr Fogarty arterial embolectomy catheter, respectively. MAP, CPP, HR, RF and RT values were measured before and after of the craniotomy. The ICP value was measured after craniotomy, every five minutes during 40 minutes after the balloon was inflated with 0.3 ml with NaCl and further 40 minutes after the balloon was inflated with 0.6 ml. The ICP value increased in both groups; however, the ICP values were lower in the flexible urethral catheter. The flexible urethral catheter can be used as an alternative method to measure ICP values in rabbits with head injury.(AU)

ABSTRACT

Cada año millones de personas alrededor del mundo sufren de Trauma de Cráneo (TEC), una sustancial proporción han muerto o se mantienen discapacitados [1]. El TEC provoca una lesión estructural y/o una disrupción fisiológica de la función cerebral; aunque en gran parte el daño cerebral definitivo depende del trauma per se, cambios inflamatorios pos-traumáticos también contribuyen al resultado final . La Universidad de Washington, a través del Dr. Randall M Chesnut y su equipo nos ha hecho llegar al Hospital de Especialidades José Carrasco Arteaga una placa de reconocimiento por el trabajo que hasta hoy se ha realizado en la Unidad de Cuidados Intensivos (UCI) del hospital y el Servicio de Neurocirugía, con la participación activa de las Dras. Soraya Puertas y Katy Trelles y con el apoyo del Dr. Marco Rivera, Coordinador General de Investigación del Hospital. Esperamos que los resultados de este estudio sirvan para optimizar el cuidado de nuestros pacientes, objetivo final de todo esfuerzo médico.

ABSTRACT

Pneumocephalus is defined as the presence of air in any of the intracranial compartments. Its most frequent causes are trauma and cranial surgery. Clinical signs occur as a result of increased intracranial pressure and vary with the location and extent of the lesion. A case involving a seven-month-old female Saint Bernard, who suffered cranial trauma caused by a bite to the face at ten days of age and had presented with seizures and localized pain four months previously is reported. A computed tomography scan of the skull revealed a nasocephalic mass with low contrast enhancement, bone lysis, and hypodensity (-940 Hounsfield units) of the lateral and third ventricles, indicating intraventricular pneumocephalus. During surgery, a fragment of the mass was collected for histopathological examination, which demonstrated the presence of multifocal areas of necrosis. The computed tomography (CT) is a reliable method for the characterization of intracranial lesions and diagnosis of pneumocephalus, whose occurrence must be considered in pathological processes in which there is increased intracranial pressure and in patients undergoing certain surgical procedures and anesthetic specific, and CT is indicated as a monitoring tool for these patients.


Pneumoencéfalo é definido como a presença de gás em quaisquer dos compartimentos intracranianos e possui como causas mais frequentes o traumatismo e cirurgias cranianas. Os sinais clínicos ocorrem como consequência do aumento de pressão intracraniana e variam conforme o local e a extensão da lesão. Relata-se o caso de uma cadela de sete meses de idade, da raça São Bernardo, que sofreu trauma por mordedura em face, quatro meses antes, apresentando crises convulsivas e sensibilidade dolorosa local desde então. O exame tomográfico do crânio revelou massa nasoencefálica com baixa captação de contraste, lise óssea e hipodensidade (-940HU) dos ventrículos laterais e terceiro ventrículo encefálico, caracterizando pneumoencéfalo intraventricular. Foi realizada intervenção cirúrgica e coleta de fragmento da massa para exame histopatológico, que demonstrou existência de necrose multifocal. O exame de tomografia computadorizada (TC) é um método confiável para a caracterização de lesões intracranianas e diagnóstico de pneumoencéfalo, cuja ocorrência deve ser considerada em processos patológicos nos quais há aumento da pressão intracraniana e em pacientes submetidos a alguns procedimentos cirúrgicos e anestésicos específicos, sendo a TC indicada como ferramenta de monitoramento desses pacientes.

ABSTRACT

Introduction The observation of multiple lesions in a skull computed tomography (CT) scan is always cause for concern because of the frequent possibility of neoplastic etiology, although granulomatous, infectious, vascular, iatrogenic, demielinating, trauma, parasitic diseases, and strokes can produce a similar aspect on radiology. A wide range of non-neoplastic conditions can mimic a brain tumor, both clinically and radiologically, representing a potential pitfall for physicians involved in patient care. The study's goal is to alert specialists to the possibility of other neoplastic and nonneoplastic etiologies in the differential diagnosis of hypodense lesions in non-contrast. Methods We performed a literature review using PubMed, Medline, Science Direct, Embase, Clinical Trials, Ebsco, and Scielo. Articles were selected in the period of 1986 to 2015. Discussion Knowledge of various etiologies when with multiple lesions appear on computed tomography allows specialists to guide the diagnosis to appropriate treatment, avoiding the irradiation of non-neoplastic lesions and unnecessary surgeries. The most common lesions were the neoplasm (74% to 86%), especially gliomas, followed by infections (8% to 15%), and infarcts (0.6% to 6%), which represent nonneoplastic lesions. Conclusion Given the relatively high percentage of wrong neuroradiology diagnoses, most cases may require histological diagnosis, because even magnetic resonance imaging (MRI) renders difculties in distinguishing such lesions.


Introdução Observação de múltiplas lesões na tomograa computadorizada de crânio (TC) é sempre motivo de preocupação por causa da possibilidade frequente de etiologia neoplásica, embora as doenças granulomatosas, infecciosas, vascular, iatrogênica, desmielinizante, trauma, e parasitárias podem produzir aspecto semelhante na radiologia. Uma ampla gama de condições não neoplásicas pode mimetizar um tumor cerebral, tanto clínica, quanto radiologicamente, representando uma armadilha potencial para os médicos envolvidos no cuidado ao paciente. O objetivo do estudo é alertar a possibilidade de outras etiologias neoplásicas e não neoplásicas no diagnóstico diferencial de lesões hipodensas em TC sem contraste. Métodos Revisão da literatura utilizando PubMed, MEDLINE, Google Scholar, Ensaios Clínicos, EBSCO, Scielo, Tópicos em radiologia. Foram selecionados por período 1986- 2015. Discussão O conhecimento de várias etiologias, quando confrontado com múltiplas lesões na tomograa computadorizada permite o direcionamento do diagnóstico para o tratamento adequado, evitando a irradiação de lesões não neoplásicas e cirurgias desnecessárias. As lesões mais frequentes são neoplasias (74% a 86%), especialmente gliomas, seguido de infecções (8% a 15%) e infartos (0,6% a 6%), que representam lesões não neoplásicas. Conclusão Como um possível resultado da percentagem relativamente elevada de diagnósticos errados neurorradiológicos, o diagnóstico histológico faz necessário, porque mesmo Ressonância pode ser difícil na diferenciação de tais lesões.

O trauma maxilofacial ‚ um dos grandes desafios para os servi‡os de sa£de e representa um dos problemas mais importantes devido … elevada taxa de incidˆncia e alto custo financeiro. A frequente associa‡Æo entre trauma craniofacial e maxilofacial exige abordagens e tratamento multiprofissional e sÆo cada vez mais complexos, com tempo de interna‡Æo mais longo e altos custos para o sistema p£blico de sa£de. Este estudo apresenta um relato de caso cl¡nico de um paciente admitido no servi‡o de emergˆncia do Hospital Municipal Salgado Filho (HMSF) – RJ, v¡tima de agressÆo f¡sica por pedra no ter‡o superior de face e submetido ao tratamento cir£rgico por equipe multiprofissinal (neurocirurgiÆo e cirurgiÆo bucomaxilofacial), com cranializa‡Æo do seio frontal e reparo do defeito ¢sseo com tela de titƒnio de reconstru‡Æo. Conclui-se neste trabalho que a proposta cir£rgica, que consistiu na cranializa‡Æo do seio frontal pelo acesso bicoronal, como tratamento proposto para o paciente, apresentou- -se satisfat¢ria, segundo as referˆncias liter rias consultadas. Sugere-se acompanhamento p¢s-operat¢rio cl¡nico e radiogr fico do paciente, uma vez que neste relato foi mencionado apenas o tratamento cir£rgico do caso.


TMaxillofacial trauma is a major challenge for health services and represents a serious problem due to its high incidence and high costs. The frequent association between craniofacial and maxillofacial trauma requires multidisciplinary approaches and treatment, and it i salso very complex, with longer hospitalization time and high costs to the public health system. This study presents a case report of a patient assisted in the emergency department of the Salgado Filho Municipal Hospital (HMSF) – RJ, victim of physical assault by stone in the upper third of the face, who underwent surgery conducted by multiprofissinal team (neurosurgeons and maxillofacial surgeon) with cranialization of the frontal sinus and repair of bone defect reconstruction with titanium screen. It was concluded that the surgical approach, which consisted of the frontal sinus cranialization using bicoronal access was satisfactory as treatment according to the researched literature. It is suggested post-operative clinical and radiographic follow-up of the patient since in this report only the surgical treatment of the case was approached.

ABSTRACT

La hipertensión intracraneal es la principal causa de mortalidad en los pacientes con lesiones craneales. En la actualidad la lesión traumática cerebral es un problema de salud pública en todo el mundo. La craniectomía descompresiva surge como una estrategia de tratamiento para los pacientes con hipertensión intracraneal refractaria a manejo médico. Este procedimiento requiere una técnica quirúrgica cuidadosa y exquisita, presentamos una revisión actualizada del procedimiento dirigida a los residentes en formación y a los neurocirujanos latinoamericanos.


Intracranial hypertension is the leading cause of mortality in patients with head injuries. Currently, traumatic brain injury is a public health problem worldwide. Decompressive craniectomy emerges as a treatment strategy for patients with intracranial hypertension refractory to medical management. This procedure requires careful surgical technique and exquisite, we present a review of the procedure intended for residents in training and Colombian neurosurgeon.

ABSTRACT

Traumatic brain injury (TBI) constitutes a major health and socioeconomic problem throughout theworld. Despite the signi!cant advances in neuroradiology and cerebral monitoring it is still dif!cult tomeasure the degree of primary brain injury and continuing secondary damage with Glasgow ComaScale score or the initial computed tomography. Predicting prognosis of TBI patients in early stages hasa vital importance and is dif!cult in some instances. The present review shows that there has been anincreasing interest in biochemical markers for traumatic brain injury during the last years. The potentialcorrelation of markers with injury and outcome measures in severe head injury is promising.


O traumatismo cranioencefálico constitui um grave problema socioeconômico em todo o mundo. Apesar dos avanços em neurorradiologia e neuromonitorização, ainda é difícil mensurar a injúria primária e prever os danos secundários dos pacientes com base somente na Escala de Coma de Glasgow ou natomogra!a de crânio da admissão. Predizer o prognóstico dos pacientes ainda em uma fase inicial é devital importância, porém muitas vezes difícil. A presente revisão mostra que há interesse cada vez maiornos marcadores biológicos relacionados ao trauma decrânio. A potencial correlação dos biomarcadoresda injúria primária com o desfecho dos pacientes com traumatismo craniano grave é promissora.

ABSTRACT

O traumatismo cranioencefálico constitui frequente causa de morbidade e mortalidade da população pediátrica. Os sintomas são variáveis, dependendo da localização da lesão e da extensão do dano encefálico subjacente. Uma avaliação completa é necessária para garantir um plano de tratamento apropriado. A intervenção fisioterapêutica é essencial para minimizar os efeitos deletérios da imobilidade, bem como para facilitar a restauração da função. O presente estudo visa demonstrar a importância do tratamento fisioterapêutico no paciente pediátrico acometido por traumatismo cranioencefálico, visto que esse tipo de lesão cerebral envolve múltiplas alterações, o que possibilita maior variabilidade de intervenções da equipe de reabilitação.
