Clinical applicability of magnetic resonance imaging in acute spinal cord trauma.

PURPOSE: To assess the clinical application of magnetic resonance imaging (MRI) in patients with acute spinal cord trauma (SCT) according to the type, extension, and severity of injury and the clinical-radiological correlation. METHODS: Diagnostic imaging [computed tomography (CT) and MRI] tests of 98 patients with acute SCT were analyzed to assess their clinical diagnostic value. The following radiological findings of SCT were investigated: vertebral compression fractures, bursts and dislocations, posterior element fractures, C1 and C2 lesions, vertebral listhesis, bone swelling, spinal canal compression, disk herniation, extradural hematoma, spinal cord contusions, spinal cord swelling, and posterior ligamentous complex (PLC) injuries. RESULTS: The radiological findings were better visualized using MRI, except for the posterior elements (p = 0.001), which were better identified with CT. A total of 271 lesions were diagnosed as follows: 217 using MRI, 154 using CT, and 100 (36.9 %) using both MRI and CT. MRI detected 117 more lesions than CT. CONCLUSION: MRI was significantly superior to CT in the diagnosis of bone swelling, PLC injury, disk herniation, spinal canal compression, spinal cord contusion and swelling present in SCT. MRI detected a larger number of lesions than CT and is highly useful for the diagnosis of soft tissue and intrathecal injuries.

Sociodemographic and Clinical Factors for Microcephaly Secondary to Teratogenic Infections in Brazil: An Ecological Study.

Microcephaly is a neurological condition characterized by anomalies in the growth of the cranial circumference. This study aims to examine the association between sociodemographic and clinical variables and the occurrence of secondary microcephaly in newborns in Brazil. It also aims to investigate the association between this congenital anomaly and teratogenic infections. This research adopts an observational approach with an ecological, descriptive, and analytical design. The sample includes infants aged ≤28 days and registered in the country's Live Births Information System from January 2015 to December 2021. Newborns were categorized into G1, consisting of newborns with one of the three infections (Zika, toxoplasmosis, or syphilis), and G2, consisting of newborns with two of the three infections. A total of 1513 samples were analyzed and divided into two groups: one infection (syphilis n = 423; toxoplasmosis n = 295; or Zika n = 739) and two infections (n = 56). The northeastern region of Brazil has the highest prevalence of microcephaly. Regarding the population profile, the Zika virus infection is more common among white mothers, while the syphilis infection is more common among black mothers. Among newborns with microcephaly, boys have a lower prevalence of toxoplasmosis infection, while girls have a lower prevalence of Zika virus infection. This study provides pertinent information on each infection and contributes to the epidemiologic understanding of the association between teratogenic infections and microcephaly.

Ventricular empyema associated with severe pyogenic meningitis in COVID-19 adult patient: Case report.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) pandemic raised global attention especially due to the severe acute respiratory symptoms associated to it. However, almost one third of patients also develop neurological symptoms. The aim of the present study is to describe the case of a previously health adult that evolved cerebral ventricular empyema in the IV ventricle during COVID-19 infection treatment. CASE DESCRIPTION: A 49-year-old man with COVID-19 developed pneumonia caused by multidrug-resistant Acinetobacter baumannii. After treating adequate treatment, sedation was switched off without showing appropriate awakening. Brain CT was performed with evidence of communicating hydrocephalus. External ventricular shunt (EVD) was implant with intraoperative cerebrospinal fluid suggestive of meningitis with a positive culture for oxacillin-sensitive Staphylococcus hominis. Twenty days after EVD, meningitis treatment was finished and with 2 negative cultures, conversion to ventriculoperitoneal shunt was performed. In the following week, during the evaluation of the patient in intensive care, quadriplegia and absence of spontaneous respiratory movement were evidenced, just maintaining head movement. Brain MRI was performed with a diagnosis of ventriculitis associated with pus collections on the IV ventricle. The patient underwent microsurgical drainage removal of the shunt, with a positive intraventricular collection culture for Klebsiella pneumoniae carbapenemase and multidrug-resistant Pseudomonas aeruginosa, without improvement in the neurological condition. After 14 weeks of hospitalization, the patient died. CONCLUSION: It is well known that COVID-19 has potential to directly attack and cause severe damage to the central nervous system; however, ventricular empyema is an extremely rare life-threatening complication.

Surgical Outcome of Microvascular Decompression for Hemifacial Spasm: Symptom Control and Quality of Life / Resultado Cirúrgico da Descompressão Microvascular no Espasmo Hemifacial: Controle de Sintomas e Qualidade de Vida

Introduction Hemifacial spasm (HFS) is characterized by a segmental myoclonus of the face muscles innervated by the ipsilateral facial nerve. The accepted pathophysiology of HFS suggests that it is a disease process of the nerve root entry zone associated with any neuro-vascular conflict. Aim Review the surgical results and outcome regarding spasm control, post-operative quality of life and morbidity of microvascular decompression (MVD) for HFS from a Brazilian neurosurgical team. Method An observational investigation was conducted with data collection from patients with hemifacial spasm treated with MVD from January 2000 to December 2015 in two different centers in the West of São Paulo State, Brazil. Results A total of 152 patients underwent MVD for the treatment of HFS, ninety-eight (64.5%) female. Eighty-seven (57.2%) patients presented right-side spasms. The most common offending vessel was the posterior inferior cerebellar artery (PICA) with 78 (51.3%) patients. According to clinical presentation, an amount of 144 (94.7%) patients presented total control of symptoms after 36 months of follow-up. Regarding quality of life, a total of 125 (82.2%) patients referred normal quality of life after MVD for HFS and 121 (96.8%) from then were able to return to work or previous occupation. Permanent facial paresis / palsy was observed in 6 (3.6%) patients. There was no surgical mortality. Conclusion MVD for the treatment of HFS is a safe and efficacious surgical procedure to control spasm. Neurosurgeons experience, adequate patient selection and good anatomical knowledge are fundamental to success of the treatment.

Introdução O espasmo hemifacial (EHF) é caracterizado por mioclonia segmentar dos músculos da face inervados pelo nervo facial ipsilateral. A fisiopatologia aceita da EHF sugere que é um processo da doença da zona de entrada da raiz nervosa associada a conflito neuro-vascular. Objetivo Revisar os resultados e desfechos cirúrgicos em relação ao controle de espasmo, a qualidade de vida pós-operatória e a morbidade da descompressão microvascular (DMV) para EHF de uma equipe de neurocirurgia brasileira. Método Realizada investigação observacional com coleta de dados de pacientes com espasmo hemifacial tratados com DMV entre janeiro de 2000 a dezembro de 2015, em dois diferentes centros do Oeste do Estado de São Paulo, Brasil. Resultados Um total de 152 pacientes foram submetidos a DMV, noventa e oito (64,5%) do sexo feminino. Oitenta e sete (57,2%) pacientes apresentavam espasmos no lado direito. O conflito mais comum foi com a artéria cerebelar inferior posterior (PICA) em 78 (51,3%) pacientes. Um total de 144 (94,7%) pacientes apresentou controle total dos sintomas após 36 meses de acompanhamento. Em relação à qualidade de vida, 125 (82,2%) pacientes referiram qualidade de vida normal após a MVD para HFS e 121 (96,8%) puderam retornar ao trabalho/ocupação anterior. Paresia/paralisia facial permanentes foram observadas em 6 (3,6%) pacientes. Não houve mortalidade cirúrgica. Conclusão DMV para o tratamento da EHF é um procedimento cirúrgico seguro e eficaz para o controle do espasmo. A experiência dos neurocirurgiões, a seleção adequada dos pacientes e o bom conhecimento anatômico são fundamentais para o sucesso do tratamento.

Spinal cord injury in elderly patients admitted to a tertiary hospital.

BACKGROUND: Spinal cord injury (SCI) has a negative impact on quality of life and healthcare costs. In recent years with the age pyramid inversion, there has been a high prevalence of SCI in the elderly. These patients must be studied in order to invest in the prevention and treatment of SCI in these patients. OBJECTIVE: To identify the characteristics and clinical aspects of spinal cord injury (SCI) in the elderly. METHODS: Retrospective study of elderly patients (≥ 60 years of age) with a clinical diagnosis of SCI. Clinical and socio-demographic variables were collected from medical records. RESULTS: Sixty-two elderly patients were studied (56% men). The patients were analyzed according to gender. Women presented compression fractures associated with thoracolumbar transition, while men presented with listhesis associated with cervical lesions and increased complications. It was found that the need for surgical intervention was higher in men. Among many characteristics that differed between the elderly and younger people (< 60 years; n = 259), in the morphological diagnosis, we observed that compression fractures and dislocation fractures were more highly associated with ages ≥ 60 and < 60, respectively. After SCI, the elderly have a higher risk for late hemodynamic instability. CONCLUSION: Elderly individuals with SCI have distinct characteristics and clinical factors related to gender and age.

Characteristics and clinical aspects of patients with spinal cord injury undergoing surgery.

OBJECTIVE: To identify the characteristics of patients with spinal cord injury (SCI) undergoing surgery. METHODS: Previously, 321 patients with SCI were selected. Clinical and socio-demographic variables were collected. RESULTS: A total of 211 patients were submitted to surgery. Fall and injuries in the upper cervical and lumbosacral regions were associated with conservative treatment. Patients with lesions in the lower cervical spine, worse neurological status, and unstable injuries were associated with surgery. Individuals undergoing surgery were associated with complications after treatment. The authors assessed whether age influenced the characteristics of patients submitted to surgery. Subjects with <60 years of age were associated with motorcycle accidents and the morphologies of injury were fracture-dislocation. Elderly individuals were associated to fall, SCI in the lower cervical spine and the morphology of injury was listhesis. Subsequently, the authors analyzed the gender characteristics in these patients. Women who suffered car accidents were associated to surgery. Women were associated with paraparesis and the morphologic diagnosis was fracture-explosion, especially in the thoracolumbar transition and lumbosacral regions. Men who presented traumatic brain injury and thoracic trauma were related to surgery. These individuals had a worse neurological status and were associated to complications. Men and the cervical region were most affected, thereby, these subjects were analyzed separately (n = 92). The presence of complications increased the length of hospital stay. The simultaneous presence of morphological diagnosis, worst neurological status, tetraplegia, sensory, and motor alterations were associated with complications. Pneumonia and chest trauma were associated with mortality. CONCLUSION: These factors enable investments in prevention, rehabilitation, and treatment.

OBJETIVO: Identificar as características de pacientes com traumatismo raquimedular (TRM) submetidos à cirurgia. MÉTODOS: Previamente, 321 pacientes com TRM foram selecionados. As variáveis clínicas e sócio-demográficas foram coletadas. RESULTADOS: Um total de 211 pacientes foram submetidos a cirurgia. A queda e lesões nas regiões cervical superior e lombosacral foram associadas com tratamento conservador. Pacientes com lesões nas regiões cervical inferior, pior status neurológico e lesões instáveis foram associados com cirurgia. Indivíduos operados foram associados com complicações após tratamento. Posteriormente, os autores avaliaram se idade influenciava as características dos pacientes submetidos à cirurgia. Sujeitos com < 60 anos foram associados com acidente motociclístico e o diagnóstico de fratura-luxação. Subsequentemente, analisaram-se as características dos sexos nestes pacientes. Mulheres que sofreram acidente automobilístico foram associadas com cirurgia. Mulheres foram associadas com paraparesia e diagnóstico morfológico de fratura explosão, principalmente nas regiões de transição tóraco-lombar e lombo-sacral. Homens que apresentaram traumatismo crânio-encefálico e torácico foram relacionados a cirurgia. Estes indivíduos tiveram um pior status neurológico e foram associados à complicação. Homens e região cervical foram mais afetadas; portanto, estes pacientes foram analisados isoladamente (n = 92). A presença de complicações aumentou a permanência hospitalar. A presença de diagnósticos morfológicos simultaneamente, pior status neurológico, tetraplegia, alteração sensório-motora foram associados com complicações. Pneumonia e traumatismo torácico foram associados com mortalidade. CONCLUSÃO: Estes fatores possibilitam investimentos em prevenção, reabilitação e tratamento.

Longer epilepsy duration and multiple lobe involvement predict worse seizure outcomes for patients with refractory temporal lobe epilepsy associated with neurocysticercosis.

OBJECTIVE: To investigate the surgical outcomes of temporal lobe epilepsy associated with hippocampal sclerosis (TLE-HS) and neurocysticercosis (NCC). METHODS: A retrospective investigation of patients with TLE-HS was conducted in a tertiary center. RESULTS: Seventy-nine (62.2%), 37 (29.1%), 6 (4.7%), and 5 (3.9%) patients were Engel class I, II, III, and IV, respectively. Fifty-two (71.2%) patients with epilepsy durations ≤ 10 years prior to surgery were seizure-free 1 year after the operation compared to 27 (50.0%) patients with epilepsy durations > 10 years (p = 0.0121). Forty-three (72.9%) patients with three or fewer lobes affected by NCC were seizure-free one year after the operation, and 36 (52.9%) patients with more than three involved lobes were seizure-free after surgery (p = 0.0163). CONCLUSIONS: Longer epilepsy durations and multiple lobe involvement predicted worse seizure outcomes in TLE-HS plus NCC patients.

Microsurgical treatment of patients with refractory epilepsy and mesial temporal cavernous malformations: Clinical experience of a tertiary epilepsy center.

BACKGROUND: Mesiotemporal cavernous malformation can occur in 10-20% of patients with cerebral cavernomas and are frequently associated with refractory. METHODS: A retrospective investigation was performed in the epilepsy clinic of a Brazilian tertiary referral epilepsy center, from January 2000 to March 2012. RESULTS: A total of 21 patients were included in the study. Thirteen patients (62%) evolved to Engel I; 5 (24%) to Engel II, 2 (10%) to Engel III, and 1 (5%) to Engel IV. We observed that 10 (48%) patients with 12 years or less of epilepsy duration evolved to Engel I and 1 (5%) to Engel II; whereas from a total of 10 patients with epilepsy duration of more than 12 years, 3 (30%) evolved to Engel I and 7 (70%) to Engel II, III, or IV (P < 0.001 [bilateral]; P1 ≠ P2). CONCLUSION: Postsurgical seizure outcome for temporal lobe epilepsy associated with mesiotemporal cavernomas is very satisfactory.

Gross-total resection of temporal low grade gliomas is a critically important factor in achieving seizure-freedom.

OBJECTIVE: To present a surgical series of patients with low grade temporal gliomas causing intractable epilepsy, focusing on long-term seizure outcome. METHOD: A retrospective study was conducted with patients with temporal low-grade gliomas (LGG). RESULTS: Sixty five patients with were operated in our institution. Males were more affected than females and the mean age at surgery was 32.3 ± 8.4 (9-68 years). The mean age at seizure onset was 25.7 ± 9.2 (11-66 years). Seizure outcome was classified according with Engel classification. After one year of follow up, forty two patients (64.6%) were Engel I; seventeen (26.2%) Engel II; four (6.2%) Engel III and two (3.1%) Engel IV. Statistically significant difference in seizure outcome was obtained when comparing the extension of resection. Engel I was observed in 39 patients (69.6%) with total resection and in only 3 (33.3%) patients with partial resection. CONCLUSION: Gross-total resection of temporal LGGs is a critically important factor in achieving seizure-freedom.

Contralateral extradural hematoma following decompressive craniectomy for acute subdural hematoma (the value of intracranial pressure monitoring): a case report.

INTRODUCTION: Decompressive surgery for acute subdural hematoma leading to contralateral extradural hematoma is an uncommon event with only few cases previously reported in the English medical literature. CASE PRESENTATION: The present study describes the case of a 39-year-old White Brazilian man who had a motorcycle accident; he underwent decompressive craniectomy for the treatment of acute subdural hematoma and evolved contralateral extradural hematoma following surgery. CONCLUSION: The present case highlights the importance of close monitoring of the intracranial pressure of severe traumatic brain injury, even after decompressive procedures, because of the possible development of contralateral extradural hematoma.

Ruptured Bilateral Pericallosal Artery Aneurysm in Mirror Position: Case Report

Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operativemanagement of ruptured bilateral PA aneurysms is feasible and effective.

Intradural Schwannoma Exacerbating the Symptoms of Degenerative Lumbar Stenosis: Case Report

Introduction Schwannoma is a common intradural slow-growing, benign and encapsulated tumor that originates from the myelin sheaths of the nerve fibers. However, a lumbar schwannoma complicating the symptoms of spinal stenosis is an extremely rare association. Aim To describe the case of a woman presenting a lumbar schwannoma in association with spinal stenosis. Case Report A 53 year-old female was referred to neurosurgical evaluation due to the worsening of a lumbar pain that was irradiating to the left inferior leg along the anterolateral surface. A neurological examination revealed motor deficits for extension of the left leg and attenuation of the left patellar reflex. Magnetic resonance imaging (MRI) showed lumbar spinal stenosis due to flavum ligament hypertrophy and disc herniation in the L3L4 and L4L5 segments, and an expansive lesion with homogeneous contrast enhancement occupying the left neuroforamen of the L3L4 segment. The patient underwent surgical resection of the tumor and decompression of the stenotic segments with posterior screw instrumentation from L3 to L5. She presented an uneventful recovery and significant improvement of the lumbar pain, and was still free of symptoms 6 months after surgery. An anatomopathological examination defined the tumor as a schwannoma (Grade I ­ World Health Organization [WHO]). Conclusion The present study highlights that lumbar schwannoma is a possible etiology complicating the symptoms of patients with previous lumbar spinal stenosis. It is important to treat both pathologies to improve the patients' symptoms.

Introdução O schwannoma é um tumor intradural comum, benigno, de crescimento lento e encapsulado que se origina da bainha de myelina das fibras nervosas. No entanto, a presença de um schwannoma lombar complicando os sintomas de estenose do canal medular é uma associação extremamente rara. Objetivos Descrever o caso de uma paciente portadora de schwannoma lombar exacerbando os sintomas de estenose do canal lombar. Relato de Caso Uma mulher de 53 anos de idade foi encaminhada para avaliação neurocirúrgica devido a relato de piora dos sintomas de dor lombar que irradiavam preferencialmente para o membro inferior esquerdo na sua face antero-lateral. O exame físico neurológico revelou a presença de déficit motor para a extensão do membro inferior esquerdo e redução do reflexo patelar esquerdo. A imagem de ressonância magnética mostrou a presença de estenose do canal lombar devido à hipertrofia do ligamento amarelo e herniações discais nos segmentos L3L4 e L4L5. Além disso, o estudo radiológico também evidenciou a presença de uma lesão expansiva ocupando o neuroforamen de L3L4 com captação homogênea do meio de contraste. A paciente foi submetida à ressecção cirúrgica do processo neoplásico e descompressão do canal medular com artrodese através de instrumentação dos segmentos L3L4L5 via posterior em um único ato operatório. A paciente apresentou uma recuperação pós-operatória adequada e mantém-se assintomática em segmento clínico seis meses após o procedimento cirúrgico. O estudo anatomo-patológico e imuno-histoquímico definiu o processo expansivo como schwannoma (Grau I da OMS). Conclusão O presente estudo destaca que o schwannoma lombar é uma possibilidade etiológica para os pacientes portadores de estenose do canal lombar que apresentam piora progressiva dos sintomas ou novos déficits neurológicos. É importante tratar as duas patologias para que o paciente obtenha melhor resultado clínico no controle dos sintomas.

Prognosis Factors in Patients with Spinal Cord Trauma / Fatores de prognóstico em pacientes com trauma raquimedular

Objective Analyze the predictors of prognosis in patients with spinal cord trauma (SCT) in a tertiary hospital. Method Study prospective with 321 patients. The analysis focused on patient-related data, cause of accident, anatomical distribution, neurologic status, associated injuries, length of hospital stay, and in-hospital complications/mortality. Results The SCT was more common in men, but women older than 50 years presented a higher risk than men of the same age. Automobile accidents, motorcycle accidents, and gunshots resulted in more injuries associated. The cervical spine involvement was directly related to an increase in the number of associated injuries, complications, and mortality. Already, the neurologic status ASIA-A was associated with an increase in the number of complications, length of stay, and mortality. Conclusion The predictive factors of prognosis in these patients included age, sex, cause of injury, anatomic distribution, and neurologic status.

Predictors of clinical complications in patients with spinomedullary injury / Preditores de complicações clínicas em pacientes com trauma raquimedular / Predictores de complicaciones en pacientes con trauma raquimedular

Objective: To analyze individuals with spinal cord injury who developed secondary clinical complications, and the variables that can influence the prognosis. Methods: A prospective study of 321 patients with spinal cord injury. The variables were collected: age, sex, cause of the accident, anatomical distribution, neurological status, associated injuries, in-hospital complications, and mortality only in patients who developed complications. Results: A total of 72 patients were analyzed (85% male) with a mean age of 44.72±19.19 years. The individuals with spinal cord injury who developed clinical complications were mostly male, over 50 years of age, and the main cause was accidental falls. These patients had longer hospitalization times and a higher risk of progressing to death. Pneumonia was the main clinical complication. With regard to the variables that can influence the prognosis of these patients, it was observed that spinal cord injury to the cervical segment with syndromic quadriplegia, and neurological status ASIA-A, have a higher risk of developing pneumonia, the most common complication, as well as increased mortality. Conclusion: Clinical complications secondary to spinal cord injury are influenced by demographic factors, as well as characteristics of the injury contributing to an increase in mortality.

Objetivo: Analisar pacientes de um hospital terciário com trauma raquimedular que evoluíram com complicações clínicas intra-hospitalares, bem como as variáveis que podem interferir no prognóstico. Métodos: Estudo prospectivo de 321 pacientes vítimas de trauma raquimedular, que coletou dados sobre as seguintes variáveis: idade, sexo, etiologia do acidente, distribuição anatômica, estado neurológico, lesões associadas, complicações clínicas e mortalidade. Foram analisados apenas os pacientes que evoluíram com complicações. Resultados: Foram analisados 72 pacientes (85% do sexo masculino), com média de idade de 44,72±19,19 anos. Esses indivíduos com trauma raquimedular evoluíram com complicações clínicas intra-hospitalares, sendo a maioria do sexo masculino e com idade superior a 50 anos, sendo a principal causa a queda acidental. Além disso, esses pacientes apresentaram maior tempo de permanência hospitalar e risco de evoluir para o óbito. A pneumonia foi a principal complicação clínica. Com relação às variáveis que podem interferir no prognóstico desses pacientes, observa-se que o trauma raquimedular no segmento cervical com quadro sindrômico de tetraplegia e o estado neurológico ASIA-A apresenta maior risco de desenvolver complicações clínicas, sendo a pneumonia a mais frequente, assim como maior risco de aumentar a mortalidade. Conclusão: As complicações clínicas secundárias ao trauma raquimedular são influenciadas por fatores demográficos, assim como por características relacionadas com a lesão, interferindo no aumento da mortalidade.

Objetivo: Analizar los pacientes en un hospital de tercer nivel con lesión de la médula espinal que tuvieron complicaciones clínicas, así como las variables que pueden influir en el pronóstico. Métodos: Estudio prospectivo de 321 pacientes con lesiones de la médula espinal, que recopiló datos sobre las siguientes variables: edad, sexo, causa del accidente, distribución anatómica, estado neurológico, lesiones asociadas, complicaciones clínicas y mortalidad. Sólo se analizaron los pacientes que desarrollaron complicaciones. Resultados: Se analizaron 72 pacientes (85% varones) con una edad media de 44,72±19,19 años. Aquellos individuos con lesión de la médula espinal progresaron con complicaciones clínicas intrahospitalarias, en su mayoría varones y mayores de 50 años, siendo la caída accidental la principal causa. Además, estos pacientes tenían una estancia hospitalaria más prolongada y riesgo de progresar a la muerte. La neumonía fue la principal complicación clínica. En cuanto a las variables que pueden influir en el pronóstico de estos pacientes, se observa que la lesión de la médula espinal en el segmento cervical con cuadro sindrómico de tetraplejía y el estado neurológico ASIA-A aporta un mayor riesgo de desarrollar complicaciones clínicas, siendo la neumonía la más frecuente, así como mayor riesgo de aumento de la mortalidad. Conclusión: Las complicaciones clínicas secundarias a la lesión de la médula espinal se ven afectadas por factores demográficos, así como por las características relacionadas con la lesión, que influyen en el aumento de la mortalidad.

Analysis of patients with spinal cord trauma associated with traumatic brain injury / Análise de pacientes com trauma raquimedular associado a traumatismo cranioencefálico / Análisis de los pacientes con traumatismos vertebrales asociados con traumatismos encefálicos

Objective: Characterize victims of spinal cord injury (SCI) associated with traumatic brain injury (TBI) and risk factors. Methods: Study conducted with 52 victims of SCI associated with TBI. The variables studied were: sex; age; marital status; occupation; educational level; religion; etiology and the lesion area; neurological condition by the ASIA scale; associated injuries and potential risk factors. Results: The male (85%), aged between 21-30 years (25%), civil status stable union (56%), low level of education (69%) and the Roman Catholic religion (77%) presented the greater number of victims. Motor vehicle accidents (58%) were the main etiology. The cervical segment had higher injury risk (RR=3.48, p<0.0001). The neurological status ASIA-E (52%), the syndromic neck pain (35%) and the rate of mild TBI (65%) were the most frequent. Complications occurred in 13 patients with increased frequency of pneumonia (62%). The length of hospital stay was significantly higher (20±28 days) and 17% of patients died. Men (RR=2.14, p=0.028) and individuals exposed to motor vehicle accidents (RR=1.91, p=0.022) showed a higher risk of these lesions concurrently. Moreover, these patients had 2.48 (p<0.01) higher risk of death than victims of SCI alone. Conclusion: The SCI associated with TBI was more frequent in men, young adults, and individuals exposed to motor vehicle accidents. The cervical spine is more likely to be affected. Furthermore, ...

Unusual penetrating cranioencephalic injury by a harpoon in a Brazilian Man / Traumatismo cranioencefalico perfurante incomum por arpão

Lesões cranianas penetrantes correspondem a uma causa incomum de traumatismo cranioencefalico diferentemente de ferimentos por projéteis de arma de fogo. A maioria dos casos relatados na literatura, embora notáveis pela gravidade, apresentam boa evolução pós-operatória. O objetivo do presente relato é descrever o caso de um homem brasileiro admitido com lesão craniana penetrante profunda por arpão e sem déficits neurológicos. Os autores discutem os principais mecanismos do trauma e realizam breve revisão científica da literatura sob os aspectos epidemiológicos e possíveis abordagens terapêuticas. O manejo neurocirúrgico precoce e apropriado, quando realizado por cirurgião experiente, pode contribuir consideravelmente no prognostico dos pacientes.
