Sural nerve grafts in subacute facial nerve injuries: a report of two cases.

Because facial nerve injuries affect the quality of life, leaving them untreated can have devastating effects. The number of patients with traumatic and iatrogenic facial nerve paralysis is considerably high. Early detection and prompt treatment during the acute injury phase are crucial, and immediate surgical treatment should be considered when complete facial nerve injury is suspected. Symptom underestimation by patients and clinical misdiagnosis may delay surgical intervention, which may negatively affect outcomes and in some cases, impair the recovery of the injured facial nerve. Here, we report two cases of facial nerve injury that were treated with nerve grafts during the subacute phase. In both cases, subacute facial nerve grafting achieved significant improvements. These cases highlight surgical intervention in the subacute phase using nerve grafts as an appropriate treatment for facial nerve injuries.

Hospitalisations and in-hospital deaths following moderate to severe traumatic brain injury in Australia, 2015-20: a registry data analysis for the Australian Traumatic Brain Injury National Data (ATBIND) project.

OBJECTIVE: To describe the frequency of hospitalisation and in-hospital death following moderate to severe traumatic brain injury (TBI) in Australia, both overall and by patient demographic characteristics and the nature and severity of the injury. DESIGN, SETTING: Cross-sectional study; analysis of Australia New Zealand Trauma Registry data. PARTICIPANTS: People with moderate to severe TBI (Abbreviated Injury Score [head] greater than 2) who were admitted to or died in one of the twenty-three major Australian trauma services that contributed data to the ATR throughout the study period, 1 July 2015 - 30 June 2020. MAJOR OUTCOME MEASURES: Primary outcome: number of hospitalisations with moderate to severe TBI; secondary outcome: number of deaths in hospital following moderate to severe TBI. RESULTS: During 2015-20, 16 350 people were hospitalised with moderate to severe TBI (mean, 3270 per year), of whom 2437 died in hospital (14.9%; mean, 487 per year). The mean age at admission was 50.5 years (standard deviation [SD], 26.1 years), and 11 644 patients were male (71.2%); the mean age of people who died in hospital was 60.4 years (SD, 25.2 years), and 1686 deaths were of male patients (69.2%). The overall number of hospitalisations did not change during 2015-20 (per year: incidence rate ratio [IRR], 1.00; 95% confidence interval [CI], 0.99-1.02) and death (IRR, 1.00; 95% CI, 0.97-1.03). CONCLUSION: Injury prevention and trauma care interventions for people with moderate to severe TBI in Australia reduced neither the incidence of the condition nor the associated in-hospital mortality during 2015-20. More effective care strategies are required to reduce the burden of TBI, particularly among younger men.

The Australian Traumatic Brain Injury National Data (ATBIND) project: a mixed methods study protocol.

BACKGROUND: Traumatic brain injury (TBI) is the largest contributor to death and disability in people who have experienced physical trauma. There are no national data on outcomes for people with moderate to severe TBI in Australia. OBJECTIVES: To determine the incidence and key determinants of outcomes for patients with moderate to severe TBI, both for Australia and for selected population subgroups, including Aboriginal and Torres Strait Islander Australians. METHODS AND ANALYSIS: The Australian Traumatic Brain Injury National Data (ATBIND) project will analyse Australia New Zealand Trauma Registry (ATR) data and National Coronial Information Service (NCIS) deaths data. The ATR documents the demographic characteristics, injury event description and severity, processes of care, and outcomes for people with major injury, including TBI, assessed and managed at the 27 major trauma services in Australia. We will include data for people with moderate to severe TBI (Abbreviated Injury Scale [AIS] (head) score higher than 2) who had Injury Severity Scores [ISS] higher than 12 or who died in hospital. People will also be included if they died before reaching a major trauma service and the coronial report details were consistent with moderate to severe TBI. The primary research outcome will be survival to discharge. Secondary outcomes will be hospital discharge destination, hospital length of stay, ventilator-free days, and health service cost. ETHICS APPROVAL: The Alfred Ethics Committee approved ATR data extraction (project reference number 670/21). Further ethics approval has been sought from the NCIS and multiple Aboriginal health research ethics committees. The ATBIND project will conform with Indigenous data sovereignty principles. DISSEMINATION OF RESULTS: Our findings will be disseminated by project partners with the aim of informing improvements in equitable system-level care for all people in Australia with moderate to severe TBI. STUDY REGISTRATION: Not applicable.

The KNTS-NCPGC strives to write and inherit the will of the society through the development of clinical practice guidelines, which are one of the outcomes representing professionalism and public interest and can be expressed in terms of "trust" and "best." In this review, the history and achievements of KNTS-NCPGC, the status of the ongoing development of guidelines, and the perspectives of the committee are covered.

Venous Injury in Patients with Blunt Traumatic Brain Injury: Retrospective Analysis of a National Cohort.

BACKGROUND: Cerebral venous injury (CVI) includes injury to a dural venous sinus or major vein and leads to poorer outcomes for patients with blunt traumatic brain injury (TBI). We sought to identify the incidence, associated factors, and outcomes associated with CVI in a large national cohort. METHODS: Adult patients with blunt TBI were identified from the National Trauma Databank (2013-2017). Outcomes included inpatient mortality, discharge disposition, stroke, length of stay (LOS), intensive care unit LOS, and duration of mechanical ventilation. Multivariate regression models were used to identify the association between exposure variables and CVI, as well as each outcome. RESULTS: There were 619,659 patients with blunt TBI who met the inclusion criteria. CVI occurred in 1792 (0.3%) patients. Mixed intracranial injury type had the strongest association with CVI (odds ratio [OR] 2.89, 95% confidence interval [CI] 2.38-3.50), followed by isolated TBI (OR 1.76, 95% CI 1.54-2.02) and skull fracture (OR 1.72, 95% CI 1.55-1.91). CVI was associated with increased odds of mortality (OR 1.38, 95% CI 1.19-1.60), nonroutine discharge (OR 1.26, 95% CI 1.12-1.40), and stroke (OR 1.95, 95% CI 1.33-2.86). It was also associated with longer LOS (ß 2.02, 95% CI 1.55-2.50) and intensive care unit LOS (ß 0.14, 95% CI 0.13-0.16). Among locations of venous injury, superior sagittal sinus injury had significant associations with mortality (OR 2.93, 95% CI 1.62-5.30) and nonroutine discharge disposition (OR 1.94, 95% CI 1.12-3.35), whereas the others did not. CONCLUSIONS: We identified a 0.3% incidence of CVI in all-comers with blunt TBI as well as several injury-related variables that may be used to guide investigation for dural venous sinus injury. CVI was associated with poorer outcomes, with superior sagittal sinus injury having the strongest association.

Tratamiento integral de la osificación heterotópica en politraumatismo con traumatismo encéfalo craneano reporte de un caso / Comprehensive treatment of heterotopic ossification in polytraumatism with traumatic brain injury case report

RESUMEN Introducción: La osificación heterotópica (OH) es una complicación descrita en los pacientes con daño neurológico. Reporte de caso: Paciente que sufrió un politraumatismo y traumatismo encéfalo craneano (TEC), con fracturas y déficit neurológico secundario al TEC, quien presentó varias osificaciones heterotópicas durante su evolución, que comprometieron el logro de los objetivos funcionales. Presentó como principal manifestación tumefacción y limitación del rango articular (RA) para la extensión de cadera y rodilla izquierda, lo que mantenía el miembro inferior izquierdo (MI) flexionado, impidiendo la bipedestación y marcha. Fue diagnosticado como osteoma secundario a trauma neurológico y recibió un manejo médico estructurado, que incluyó la intervención quirúrgica: "resección del osteoma y tenotomía en isquiotiobiales", obteniendo mejora del rango articular, logrando la bipedestación y marcha con apoyo biomecánico. Discusión: La fisiopatología se cree que está relacionada a la liberación sistémica de sustancias estimulantes de células madre pluripotenciales, que se diferencian como osteoblastos. Conclusión: Un manejo integral multidisciplinario provee mejores resultados funcionales, lo que contribuye a la meta de la independencia.

ABSTRACT Introduction: Heterotopic ossification (OH) is a complication described in patients with neurological damage. Case report: Patient who suffered a multiple trauma and traumatic brain injury (TBI), with fractures and neurological deficit secondary to TBI, who presented several heterotopic ossifications (OH) during his evolution that compromised the achievement of functional objectives. The main manifestation was swelling and limitation of the articular range (RA) for the extension of the left hip and knee, which kept the lower left limb (MI) flexed, preventing standing and walking. He was diagnosed as osteoma secondary to neurological trauma and received structured medical management, which included surgical intervention: "resection of the osteoma and tenotomy in hamstrings", obtaining improvement of the joint range, chieving standing and walking with biomechanical support. Discussion: The pathophysiology is believed to be related to the systemic release of stimulating substances from pluripotent stem cells, which differentiate as osteoblasts. Conclusion: A multidisciplinary comprehensive management provides better functional results, which contributes to the goal of the independence.

[Functional reconstruction in traumatic paralysis]. / Funktionelle Rekonstruktionen bei traumatischen Lähmungen.

BACKGROUND: Traumatic nerve injuries are associated with a high morbidity and long rehabilitation times. The extent of a nerve lesion and the related regeneration potential can often only be estimated during the course, whereby the time window for successful surgical interventions is limited. OBJECTIVE: The incidence and distribution of traumatic nerve lesions are reported. Algorithms for treatment decisions are presented. MATERIAL AND METHODS: Statistics from the German TraumaRegister DGU® as well as international registers were evaluated. The results of basic research and expert recommendations for diagnostics and treatment are discussed. RESULTS AND CONCLUSION: A strategic approach to conservative and surgical treatment of traumatic nerve injuries depending on the extent of injury and resulting regeneration potential is recommended. In conjunction with the clinical course, electrophysiology and imaging diagnostics, e.g. nerve sonography, can help to differentiate between neurapraxia, axonotmesis and neurotmesis.

Traumatic spinal cord injury in Victoria, 2007-2016.

OBJECTIVE: To investigate trends in the incidence and causes of traumatic spinal cord injury (TSCI) in Victoria over a 10-year period. DESIGN, SETTING, PARTICIPANTS: Retrospective cohort study: analysis of Victorian State Trauma Registry (VSTR) data for people who sustained TSCIs during 2007-2016. MAIN OUTCOMES AND MEASURES: Temporal trends in population-based incidence rates of TSCI (injury to the spinal cord with an Abbreviated Injury Scale [AIS] score of 4 or more). RESULTS: There were 706 cases of TSCI, most the result of transport events (269 cases, 38%) or low falls (197 cases, 28%). The overall crude incidence of TSCI was 1.26 cases per 100 000 population (95% CI, 1.17-1.36 per 100 000 population), and did not change over the study period (incidence rate ratio [IRR], 1.01; 95% CI, 0.99-1.04). However, the incidence of TSCI resulting from low falls increased by 9% per year (95% CI, 4-15%). The proportion of TSCI cases classified as incomplete tetraplegia increased from 41% in 2007 to 55% in 2016 (P < 0.001). Overall in-hospital mortality was 15% (104 deaths), and was highest among people aged 65 years or more (31%, 70 deaths). CONCLUSIONS: Given the devastating consequences of TSCI, improved primary prevention strategies are needed, particularly as the incidence of TSCI did not decline over the study period. The epidemiologic profile of TSCI has shifted, with an increasing number of TSCI events in older adults. This change has implications for prevention, acute and post-discharge care, and support.

Henrique Dumont: how a traumatic brain injury contributed to the development of the airplane / Henrique Dumont: como um traumatismo cranioencefálico contribuiu para o desenvolvimento do avião

ABSTRACT The life and death of Henrique Dumont (1832-1892) is little known, being usually remembered as Alberto Santos-Dumont's father. This report describes the history of this Brazilian engineer, also known as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic. This forced him to sell the farm and move to France for treatment. Before his death two years later, he gave his 18-year-old son bits of advice, and distributed his inheritance, which allowed Alberto to study in Paris and finance his experiments that would culminate in the development of the airplane. The diagnostic and therapeutic possibilities are also discussed.

RESUMO A vida e especialmente a morte do brasileiro Henrique Dumont (1832-1892) são pouco conhecidas, sendo geralmente lembrado como pai de Alberto Santos Dumont. Relatamos a história deste engenheiro que obteve enorme sucesso empresarial no final do século XIX, sendo denominado Rei do Café. Em 1890, durante a inspeção da sua fazenda, maior cafeicultura do mundo na época, caiu da charrete e ficou hemiplégico. Isso o fez vender a fazenda e buscar tratamento na França, trazendo o primeiro automóvel do Brasil ao retornar. Antes de morrer dois anos após o acidente, deu valorosos conselhos e distribuiu sua herança ao filho Alberto, então com dezoito anos de idade, que pôde assim estudar em Paris e financiar seus experimentos que culminariam no desenvolvimento do avião. São discutidas e contemporizadas as possibilidades diagnósticas e terapêuticas relacionadas ao déficit neurológico.

Evaluation of two collagen conduits and autograft in rabbit sciatic nerve regeneration with quantitative magnetic resonance DTI, electrophysiology, and histology.

BACKGROUND: We compared different surgical techniques for nerve regeneration in a rabbit sciatic nerve gap model using magnetic resonance diffusion tensor imaging (DTI), electrophysiology, limb function, and histology. METHODS: A total of 24 male New Zealand white rabbits were randomized into three groups: autograft (n = 8), hollow conduit (n = 8), and collagen-filled conduit (n = 8). A 10-mm segment of the rabbit proximal sciatic nerve was cut, and autograft or collagen conduit was used to bridge the gap. DTI on a 3-T system was performed preoperatively and 13 weeks after surgery using the contralateral, nonoperated nerve as a control. RESULTS: Overall, autograft performed better compared with both conduit groups. Differences in axonal diameter were significant (autograft > hollow conduit > collagen-filled conduit) at 13 weeks (autograft vs. hollow conduit, p = 0.001, and hollow conduit vs. collagen-filled conduit, p < 0.001). Significant group differences were found for axial diffusivity but not for any of the other DTI metrics (autograft > hollow conduit > collagen-filled conduit) (autograft vs. hollow conduit, p = 0.001 and hollow conduit vs. collagen-filled conduit, p = 0.021). As compared with hollow conduit (autograft > collagen-filled conduit > hollow conduit), collagen-filled conduit animals demonstrated a nonsignificant increased maximum tetanic force. CONCLUSIONS: Autograft-treated rabbits demonstrated improved sciatic nerve regeneration compared with collagen-filled and hollow conduits as assessed by histologic, functional, and DTI parameters at 13 weeks.

Lumbar burner and stinger syndrome in an elderly athlete.

Burner or stinger syndrome is a rare sports injury caused by direct or indirect trauma during high-speed or contact sports mainly in young athletes. It affects peripheral nerves, plexus trunks or spinal nerve roots, causing paralysis, paresthesia and pain. We report the case of a 57-year-old male athlete suffering from burner syndrome related to a lumbar nerve root. He presented with prolonged pain and partial paralysis of the right leg after a skewed landing during the long jump. He was initially misdiagnosed since the first magnet resonance imaging was normal whereas electromyography showed denervation. The insurance company refused to pay damage claims. Partial recovery was achieved by pain medication and physiotherapy. Burner syndrome is an injury of physically active individuals of any age and may appear in the cervical and lumbar area. MRI may be normal due to the lack of complete nerve transection, but electromyography typically shows pathologic results.

PERIPHERAL NERVE INJURY IN SPORTS.

- Peripheral nerve injuries in sports are rare. Peripheral nerve injuries in sports are caused by pressure, stretching, or bone fracture. Peripheral nerve injuries are more frequent on upper limbs, and the type of injury is determined by the type of sport. According to Seddon, we distinguish 3 levels of injury: 1) neurapraxia; 2) axonotmesis; and 3) neurotmesis. Diagnosis must be reached as early as possible to enable timely initiation of appropriate treatment. The diagnostics of peripheral nerve injuries includes electromyography and nerve conduction studies, somatosensory evoked potentials, magnetic resonance imaging, and ultrasound. Proximal nerve injuries have a poorer prognosis for neurologic recovery.

[Overexpression of TRPV1 after periphery nerve injury attenuates nerve regeneration in rats].

Objective: To observe the effect of the expressive or functional blockage of TRPV1 on nerve regeneration after sciatic trans-section injury. Methods: AMG-517, a kind of TRPV1 inhibitor, was injected into the surrounding area of the ipsilateral lumbar dorsal root ganglia while unilateral sciatic nerve was transected. A total of 24 healthy male Sprague-Dawley rats were divided into 4 groups: control group, injury only group, injury+ AMG-517 150 µg/kg group, injury+ AMG-517 300 µg/kg group. The injury only group was injected the same volume of medium. The release of CGRP from dorsal-horn of spinal cord, the number of axons at proximal stem of sciatic nerve after transection, and the expression of TRPV1 in dorsal root ganglion were detected using the methods of ELISA, Western blot and semi-thin section (1 µm)- toluidine blue staining 2 weeks after injury. Results: The release of CGRP in lumbar spinal dorsal horn was obviously decreased after AMG-517 treatment, which was the evidence of TRPV1 functional inhibition. CGRP in the control group was 0.15 ng/g, the injury only group 0.17 ng/g, AMG-517 150 µg/kg group 0.09 ng/g, and AMG-517 300 µg/kg group 0.11 ng/g(P<0.01). The number of axons which were myelinated or unmyelinated increased after the TRPV1 was inhibited by AMG-517(P<0.01). In addition, the injection of AMG-517 into surrounding dorsal root ganglion decreased the expression of TRPV1 in dorsal root ganglion(P<0.01). Conclusions: Over expression or activation of TRPV1 after periphery nerve injury has negative effect on nerve regeneration in fact; Inhibiting the over-expression or over-activation of TRPV1 after nerve injury facilitates axonal regeneration and nerve repair.

Síndrome de Brown-Séquard em associação à síndrome de Horner / Brown Sequard Syndrome In Association With Horner Syndrome

O trauma raquimedular (TRM) é uma importante causa de incapacidade, sendo constatado uma incidência média de 21 pacientes por milhão de habitantes por ano por uma revisão sistemática realizada nas cinco regiões do pais em. Em Belo Horizonte essa incidência chegou a 26 pacientes por milhão por ano. Trata-se de AFC, 28 anos, que foi encaminhado com urgência para o Hospital João XXIII com história de agressão por arma branca (um facão) na região supra clavicular esquerda no dia 22/10. Ao exame neurológico o paciente encontrava-se consciente, orientado e com hemiplegia á esquerda. Anestesia tátil e vibratória á esquerda (lesão do trato corticoespinhal e fascículo grácil e cuneiforme) e preservada á direita, além de anestesia térmica/dolorosa contralateral a hemissecção (lesão do trato espinotalâmico), que configuram a síndrome de Brown Sequard completa. Foi realizada tomografia computadorizada da coluna que evidenciou fratura de lâmina de T1. A ferida lacerante foi suturada e paciente manteve quadro estável por 5 dias. Após 7 dias da admissão hospitalar constatou-se anisocoria com pupila miótica à esquerda eptose de pálpebra também a esquerda, que configura a síndrome de Horner concomitantemente. Foi realizada punção lombar constatando liquor hemorrágico e com alta celularidade, iniciado antibioticoterapia com Meropenem e Vancomicina. Relata-se a correlação anátomoclínica de paciente vitima de TRM aberto, com síndromes associadas, de hemissecção medular e Horner. Ressalta-se a importância dos conhecimentos em neuroanatomia. (AU)

Spinal cord trauma is an important cause of disability, with an average incidence of 21 patients per million inhabitants per year by a systematic review in the five regions of Brazil. In Belo Horizonte, this incidence reached 26 patients per million per year. This is the AFC, 28 years old, who was referred urgently to the Hospital João XXIII with a history of white-collar aggression (a machete) in the left supraclavicular region on 22/10. At the neurological examination the patient was conscious, oriented and with left hemiplegia. Tactile and vibratory anesthesia to the left (lesion of the corticospinal tract and gracile and cuneiform fasciculus) and preserved to the right, in addition to thermal / painful anesthesia contralateral to the hemisection (lesion of the spinothalamic tract), which constitute the complete Brown Sequard syndrome. Computed tomography of the spine was performed, showing a T1 fracture. The lacerating wound was sutured and patient maintained stable frame for 5 days. After 7 days of hospital admission, anisocoria was observed with miotic pupil on the left and ptosis of the eyelid also on the left, which configures Horner syndrome concomitantly. A lumbar puncture was performed, confirming hemorrhagic and high cellularity, and antibiotic therapy with Meropenem and Vancomycin. The anatomic-clinical correlation of a patient with open MTR with associated syndromes of medullary and Horner hemisection is reported. The importance of knowledge in neuroanatomy is emphasized.

Acute spinal cord injury.

Acute spinal cord injury (SCI) is a devastating event with high mortality and, among survivors, a high degree of morbidity due to both motor and sensory deficits. The damage that occurs with a SCI is recognized to be pathophysiologically biphasic: the initial insult to neural tissue can be followed by a secondary process of progressive ischemia that may worsen the severity of dysfunction. The extent of this secondary insult is potentially modifiable, and a variety of interventions have been studied in an attempt to improve motor and sensory outcomes. What follows is a brief review of some such procedural and pharmacologic interventions, including early decompressive surgery, use of methylprednisolone, and blood pressure and respiratory management, which have been proposed to improve outcomes after SCI.

Positive Outcome After a Small-Caliber Gunshot Fracture of the Upper Cervical Spine without Neurovascular Damage.

BACKGROUND: Gunshot wounds to the cervical spine most frequently concur with serious injuries to the spinal cord and cervical vessels and often have a fatal outcome. CASE REPORT: We describe the case of a 35-year-old male with a complex fracture of the C2 vertebra body and a mandibular fracture after a penetration gunshot to the cervical spine. Computed tomography (CT) at admission revealed the exact extent of the fractures and the small caliber bullet lodged next to the C2 vertebra. In this rare and extremely lucky case no collateral vascular or neurological damage was detected. Eighteen months after surgical bullet removal and posterior C1-C3 fusion complete bone healing of the C2 vertebra was achieved and there were no secondary neurovascular deficits. CONCLUSIONS: Immediate surgical C1-C3 fixation resulted in an excellent outcome without secondary neurovascular deficits in this rare case of traumatic complex C2 vertebral fracture caused by a gunshot injury.
