Is there a correlation between the spinal instability neoplastic score and mechanical pain in patients with metastatic spinal cord compression? A prospective cohort study.

INTRODUCTION: The decision for selecting patients for surgical treatment of metastatic spinal cord compression (MSCC) is challenging even for experienced surgeons. Recently, the spinal instability neoplastic score (SINS) has been proposed to help surgeons in the evaluation of spinal stability in the setting of spinal metastases. This study aimed to evaluate the correlation between SINS and preoperative visual analog scale (VAS), as well as the pre- and post-operative association of the VAS and neurological function. METHODS: A prospective cohort study was conducted in a tertiary referral cancer center. Seventy-nine patients with MSCC were surgically treated from June 2012 to March 2015. Pain status before and after surgery was assessed using VAS score, and neurological status was evaluated using the American Spine Injury Association Impairment Scale (AIS) before and after surgery. Pain was classified as VAS (0-4) none or mild pain; VAS (5-8) moderate pain; and VAS (9-10) as severe pain. Neurological function was scored as AIS A: Complete deficits, AIS B-D: Incomplete deficits, AIS E: Neurologically intact. SINS degrees were classified as 0-6-stable; 7-12 potentially unstable, and 13-18-unstable. Spearman's correlation coefficient test was utilized for correlation between pain and SINS; Chi-square association test was utilized for evaluating pre- and post-operative pain and AIS, as well as the association between SINS and tumor types. RESULTS: A higher SINS correlates with severe mechanical pain preoperatively (ρ = 0.38, P = 0.001); surgical procedure improved neurological function (P = 0.0001), and decrease pain (P = 0.84). Finally, a higher SINS was also associated with osteolytic tumors (P = 0.03). CONCLUSIONS: The SINS correlates with mechanical pain. Surgery provides a significant improvement in pain and neurological status, especially in patients who presented higher SINS scores and some degree of preoperative neurological function.

Severe Lateral Thoracic Fracture-Dislocation without Neurological Deficit ­ Case Report

Introduction A case report of a thoracic fracture-dislocation (T11­T12) without neurological deficit is presented. Objective Report the diagnosis and treatment of a traumatic severe fracture with lateral dislocation at the thoracolumbar junction without neurological deficit. Background Fracture-dislocation of the thoracic spine without neurological deficit is a rare lesion. We retrieved only 15 cases reported in the literature. Surgical treatment with spinal decompression, fusion and realignment is the treatment of choice. Case A 40-year-old man suffered a bicycle accident and was admitted with severe back pain but neurologically intact. He was treated with a wide laminectomy and spinal cord decompression followed by correction of his deformity using pedicle screw instrumentation and rod maneuvers. Results After three days, the patient was able to walk, and after one month he had just mild back pain, but was neurologically intact, and was able to return to his usual daily activities. After six months, he was neurologically intact and performing routine physical activities. Conclusions Fracture-dislocation of the thoracic spine without neurological deficit is a rare injury. A good outcome can be obtained with modern spinal stabilization surgical techniques, avoiding late neurological deterioration.

Computed tomography evaluation of the normal craniocervical junction craniometry in 100 asymptomatic patients.

OBJECT: Most of the craniometric relationships of the normal craniocervical junction (CCJ), especially those related to angular craniometry, are still poorly studied and based on measurements taken from simple plain radiographs. In this study, the authors performed a craniometric evaluation of the CCJ in a population without known CCJ anomalies. The purpose of the study was to evaluate the normal CCJ craniometry based on measurements obtained from CT scans. METHOD: The authors analyzed 100 consecutive CCJ CT scans obtained in adult patients who were admitted at their tertiary hospital for treatment of non-CCJ conditions between 2010 and 2012. A total of 17 craniometrical measurements were performed, including the relation of the odontoid with the cranial base, the atlantodental interval (ADI), the clivus length, the clivus-canal angle (CCA)-the angle formed by the clivus and the upper cervical spine, and the basal angle. RESULTS: The mean age of the 100 patients was 50.6 years, and the group included 52 men (52%) and 48 women (48%). In 5 patients (5%), the tip of the odontoid process was more than 2 mm above the Chamberlain line, and in one of these 5 patients (1% of the study group). it was more than 5 mm above it. One patient had a Grabb-Oakes measurement above 9 mm (suggesting ventral cervicomedullary encroachment). The mean ADI value was 1.1 mm. The thickness of the external occipital protuberance ranged from 7.42 to 22.36 mm. The mean clivus length was 44.74 mm, the mean CCA was 153.68° (range 132.32°-173.95°), and the mean basal angle was 113.73° (ranging from 97.06°-133.26°). CONCLUSIONS: The data obtained in this study can be useful for evaluating anomalies of the CCJ in comparison with normal parameters, potentially improving the diagnostic criteria of these anomalies. When evaluating CCJ malformations, one should take into account the normal ranges based on CT scans, with more precise bone landmarks, instead of those obtained from simple plain radiographs.

Aplicação da escala SF-36 em pacientes operados de tumores da base do crânio / Application of SF-36 scale in patients operated on skull base tumors

Introdução: A base do crânio é uma região que pode ser afetada por diferentes tipos de tumores. Os tumores dessa região podem ser benignos ou malignos e se localizarem na cavidade anterior, média ou posterior do crânio. Embora relativamente raras, essas lesões podem afetar significativamente os pacientes em virtude de sua localização anatômica complexa e riscos próprios do manejo cirúrgico. A qualidade de vida de pacientes operados de tumores da base do crânio pode ser prejudicada não somente pelo comprometimento neurológico resultante da lesão anatômica, mas também por problemas psicossociais tais como diminuição da autoconfiança e autoestima, mudança nas atividades de vida diária, dependência, estigma, discriminação, dificuldade de interação social, desemprego, entre outras. Dessa forma, o objetivo deste estudo foi avaliar a qualidade de vida dos pacientes operados de tumores da base do crânio. Método: O estudo incluiu 38 indivíduos que foram avaliados entre seis meses e um ano após a cirurgia usando a escala de qualidade de vida SF-36. Resultados: Todos os pacientes tiveram pontuação acima de 50. Em seis dos oito domínios, nos componentes físico e mental, mulheres pontuaram melhor que homens, especialmente em LAF (limitação por aspectos físicos). Quando comparadas as idades, pacientes acima de 50 anos pontuaram melhor. Quando comparados os sexos, mulheres até 50 anos pontuaram melhor que os homens. Por outro lado, homens com idade superior a 50 anos pontuaram melhor que as mulheres. Conclusão: Embora haja diferenças, estas não foram estatisticamente significantes. Assim, não houve melhora significativa nos quesitos social, físico, psicológico e funcional quando idade e sexo foram comparados.

Background: The skull base is a region that may be affected by different types tumors. Tumors in this region can be benign or malignant and are located in the anterior fossa, middle or posterior fossa. Although relatively rare, they are potentially harmful, because of the complex anatomic features of these regions and the inherent risk of a surgical procedure. The quality of life of patients can be hampered not only by neurological impairment, but also by psychosocial problems such as decreased self-confidence and self-esteem, change in daily activities, dependency, stigma and discrimination, difficulty in social interaction and unemployment. Thus, the aim of this study was to assess the quality of life of patients operated on for tumors of the skull base. Method: The study included 38 individuals who were evaluated between six months and one year after surgery, using the SF-36. Results: All patients had scores above 50 when all domains were summed up. In six out of eight domains (physical and mental components) women scored better than men, especially in LAF (limitation due to physical abilities). When compared to age, patients older than 50 years scored better. When compared with gender, women until 50 years had a better score. On the other hand, men aged over 50 years scored better than women. Conclusion: Although there are slight differences, these were not statistically significant. We concluded that no significant improvement occurred in social, physical, psychological and functional outcome when age and sex were compared.

Evaluation of the thoracolumbar injury classification system in thoracic and lumbar spinal trauma.

STUDY DESIGN: Retrospective study. OBJECTIVE: Evaluate the relationship among the neurologic status, the Thoracolumbar Injury Classification System (TLICS) score, and the Magerl/AO classification system. SUMMARY OF THE BACKGROUND DATA: A wide range of classification schemes for thoracic and lumbar spine trauma have been described, but none has achieved widespread acceptance. A recent system proposed by Vaccaro et al has been developed to improve injury classification and guide surgical decision making. METHODS: Analysis of 49 patients treated surgically for thoracic and lumbar spine trauma from 2003 to 2009 in 2 spine trauma centers. Clinical and radiologic data were evaluated, classifying the trauma according to American Spinal Injury Association status, the Magerl/AO classification for fractures, and the TLICS score. RESULTS: The mean age was 37 years (range, 17-72). Thirty-five (71%) patients had a thoracolumbar fracture (T11-L2). A posterior approach was used in all the cases. American Spinal Injury Association status remained unchanged in 44 (4 had some improvement and 1 worsened). A total of 61.1% of the patients with a type A fracture were neurologically intact compared with 80% with complete neurologic deficit for type C fractures. The TLICS score range from 2 to 9 (average of 6.2). Forty-seven of 49 (96%) patients had a TLICS score greater than 4, suggesting surgical treatment. Seventy percentage of the patients with a TLICS score from 4 to 6 were neurologically intact compared with 87.5% of complete neurologic deficits in patients with TLICS 7 to 9. A statistic correlation was established between the neurologic status and AO type fracture (P = 0.0041) and the TLICS score (P < 0.0001). An association between the AO type fracture and the TLICS score was also found (P = 0.0088). CONCLUSION: The TLICS score treatment recommendation matched surgical treatment in 47 of 49 patients (96%). The TLICS was found to correlate to the AO classification. This suggests that the TLICS can be used to classify thoracolumbar trauma and can accurately predict surgical management.

Surgical management of trigeminal schwannomas.

OBJECT: The authors provide a detailed review of the surgical management of trigeminal schwannomas (TSs) and also discuss the best surgical approach based on the surgical anatomy and tumor extension. METHODS: A series of 17 patients with TSs who were surgically treated between 1987 and 2008 at the authors' institution is reported. The lesions were small (< 3 cm) in 2, medium (between 3 and 4 cm) in 5, large (> 4 cm) in 6, and giant (> 5 cm) in 4 cases. Preoperative symptoms included trigeminal hypesthesia (53%), facial pain (53%), headaches (35.3%), hearing impairment (17.6%), seizures (17.6%), diplopia (11.8%), ataxia (11.8%), and hemiparesis and increased intracranial pressure with papilledema (5.9%). The mean follow-up duration was 10.5 years (121.6 months), with an average of 0.8 patients per year. RESULTS: Total tumor excision was possible in 16 patients, with no surgery-related deaths. Postoperative trigeminal anesthesia was observed in 7; trigeminal motor function was preserved in 7. Two developed cerebrospinal fluid leakage, 2 presented with mild facial palsy, and 1 patient with neurofibromatosis Type 2 had recurrence of the tumor, which was uneventfully removed. Of the 9 who reported facial pain, only 1 remained symptomatic postoperatively. CONCLUSIONS: The best treatment for TSs is complete microsurgical removal. Postoperative preservation of trigeminal nerve function is possible when resection of the lesion is performed at well-established skull base neurosurgical centers. Although good results have been reported with radiosurgery, no cure can be obtained with this therapeutic modality. Instead, this treatment should be reserved only for nonresectable and residual tumors within the cavernous sinus.

Acoustic neuroma (vestibular schwannoma): surgical results on 240 patients operated on dorsal decubitus position.

OBJECTIVE: To evaluate the result of the surgical treatment of vestibular schwannoma (VS) operated in dorsal decubitus (mastoid position). METHOD: 240 patients with a VS underwent a retrosigmoid craniotomy for tumor resection in dorsal decubitus (mastoid position). The function of 7th and 8th cranial nerves was monitored during surgery and the opened internal auditory canal (IAC) was reconstructed using a vascularized dura flap, muscle and fibrin glue. RESULTS: Complete tumor removal was achieved in 99% of the cases, with a mortality of 1.6%. The facial nerve function was preserved in 85% of cases and hearing in 40% of the patients (with preoperative hearing) with tumors of up 1.5 cm in diameter. The incidence of cerebrospinal fluid leak was 5.8% and meningitis 2.9%. Venous air embolism was registered in 3% of cases; it was not associated to mortality. CONCLUSION: Surgical removal of VS in dorsal position has several advantages; the morbidity and mortality are very low.

Reconstruction of the cranial base in surgery for jugular foramen tumors.

OBJECTIVE: The surgical removal of a jugular foramen (JF) tumor presents the neurosurgeon with a complex management problem that requires an understanding of the natural history, diagnosis, surgical approaches, and postoperative complications. Cerebrospinal fluid (CSF) leakage is one of the most common complications of this surgery. Different surgical approaches and management concepts to avoid this complication have been described, mainly in the ear, nose, and throat literature. The purpose of this study was to review the results of CSF leakage prevention in a series of 66 patients with JF tumors operated on by a multidisciplinary cranial base team using a new technique for cranial base reconstruction. METHODS: We retrospectively studied 66 patients who had JF tumors with intracranial extension and who underwent surgical treatment in our institutions from January 1987 to December 2001. Paragangliomas were the most frequent lesions, followed by schwannomas and meningiomas. All patients were operated on using the same multidisciplinary surgical approach (neurosurgeons and ear, nose, and throat surgeons). A surgical strategy for reconstruction of the cranial base using vascularized flaps was carried out. The closure of the surgical wound was performed in three layers. A specially developed myofascial flap (temporalis fascia, cervical fascia, and sternocleidomastoid muscle) associated to the inferior rotation of the posterior portion of the temporalis muscle was used to reconstruct the cranial base with vascularized flaps. RESULTS: In this series of 66 patients, postoperative CSF leakage developed in three cases. These patients presented with very large or recurrent tumors, and the postoperative CSF fistulae were surgically closed. The cosmetic result obtained with this reconstruction was classified as excellent or good in all patients. CONCLUSION: Our results compare favorably with those reported in the literature. The surgical strategy used for cranial base reconstruction presented in this article has several advantages over the current surgical techniques used in cases of JF tumors.

Intradural jugular foramen tumors.

Eleven patients with jugular foramen lesions with or without extradural extension were operated at University Hospital of Campinas (UNICAMP), in Campinas, Brazil, between 1998 and 2001. Neck dissection, mastoidectomy without transposition of the facial nerve and myofascial flap reconstruction of the cranial base with an especially developed technique were carried out in 7 patients. Four patients were operated using retrosigmoid craniectomy. Total excision was accomplished in 9 cases. All patients did not show evidence of disease progression at least after 2 years follow-up. There was no mortality. New lower cranial nerve deficits occurred in 5 patients. Nine maintain or improved their preoperative status based on Karnofsky and Glasgow Outcome Scale. A complex anatomy of this region demand wide exposures for treat those tumors. For this reason, an adequate approach for curative resection of most lesions and an efficient skull base reconstruction decreasing postoperative morbidity are essential.

Intradural jugular foramen tumors

Onze pacientes com lesões expansivas do forame jugular associadas ou não a componente extradural foram submetidos a ressecção cirúrgica no Hospital das Clínicas da Universidade Estadual de Campinas (UNICAMP) entre 1998 e 2001. Foi utilizada cirurgia combinada com dissecção do pescoço, mastoidectomia sem transposição do nervo facial e técnica de reconstrução miofascial da base do crânio desenvolvida por um dos autores. Quatro pacientes foram operados via craniectomia retrosigmoidea. Ressecção total foi feita em 9 pacientes, subtotal em um e parcial em outro. Nenhum dos 11 pacientes teve progressão da doença em 2 anos de acompanhamento. Não houve mortalidade. Cinco pacientes tiveram déficits adicionais de nervos cranianos baixos. Nove pacientes mantiveram ou melhoraram suas pontuações de acordo com a escala de Karnofsky. Para adequada abordagem do paciente com tumor de forame jugular, são necessários bom conhecimento anatômico da região, exposição cirúrgica ampla, e técnica de reconstrução eficiente para obter cura com baixas taxas de complicações pós-operatórias.

Chronic epidural hematoma of the vertex.

Epidural hematomas of the cranial vertex can be rarely found in patients victims of head trauma. The diagnosis of the vertex hematoma may be delayed by the odd location of the bleeding site and the absence of a clear localization symptomatology. The current method of choice for investigation of head trauma patients, the computed tomography (CT) scans, may also give misleading diagnostic clues. Epidural hematomas of the vertex can be also encountered in a chronic form, and re-bleeding is possibly the underlying mechanism for the long term permanence of the hematoma. We report a case of a patient with a chronic epidural hematoma of the cranial vertex with a long interval between the trauma and the symptoms onset. We review the current literature focusing on the diagnostic pitfalls and forms of treatment of the chronic epidural hematoma of the vertex.

Double-checked preoperative localization of brain lesions.

We describe two simple methods that can be used together or alone to localize brain convexity lesions. These methods are based on computerized tomography or magnetic resonance imaging to calculate the position of a given lesion under the skin and help neurosurgeons to plan their surgical approaches. Using spatial fixed points traced on the radiological scans and transposing them to the skin scalp allows the lesion to be projected or drawn on the calvaria.

Risk factors and outcome in 100 patients with aneurysmal subarachnoid hemorrhage

OBJECTIVE: Clinical and surgical outcome of patients with subarachnoid hemorrhage (SAH) due to ruptured aneurysm were assessed in comparison to pre-operative data and risk factors such as previous medical history, clinical presenting condition, CT findings and site of bleeding. METHODS: We evaluated 100 consecutive patients with aneurysmal SAH. Gender, color, history of hypertension, smoking habit, site and size of aneurysm, admittance and before surgery Hunt Hess scale, need for cerebro-spinal fluid shunt, presence of complications during the surgical procedure, Glasgow Outcome Scale, presence of vasospasm and of rebleeding were assessed and these data matched to outcome. For statistical analysis, we applied the chi-squared test or Fisher's test using the pondered kappa coeficient. Kruskal-Wallis test was used for comparison of continue variables. Tendency of proportion was analyzed through Cochran-Armitage test. Significance level adopted was 5 percent. RESULTS: Patients studied were mainly white, female, without previous history of hypertension and non-smokers. Upon hospital admittance, grade 2 of Hunt-Hess scale was most frequently observed (34 percent), while grade 3 of Fisher scale was the most prevalent. Single aneurysms were most frequent at anterior circulation, between 12 and 24 mm. The most frequent Glasgow Outcome Scale observed was 5 (60 percent). Hunt Hess upon the moment of surgery and presence of complications during surgical procedure showed positive correlation with clinical outcome (p=0.00002 and p=0.001, respectively). Other variables were not significantly correlated to prognosis. Tendency of proportion was observed between Hunt-Hess scale and Fisher scale. CONCLUSION: Among variables such as epidemiological data, previous medical history and presenting conditions of patients with ruptured aneurysms, the Hunt-Hess scale upon the moment of surgery and the presence of surgical adversities are statistically related to degree of disability

Orbital apex syndrome due to aspergillosis: case report

We report the case of a 73-year-old female who presented facial numbness and pain in the first division of the trigeminal nerve, ptosis, diplopia and visual loss on the right side for the previous four months. The neurological, radiological and histological examination demonstrated a rare case of invasive fungal aspergillosis of the central nervous system, causing orbital apex syndrome, later transformed in temporal brain abscess. She died ten months later due to respiratory and renal failure in spite of specific antimycotic therapy

Pilocytic astrocytoma following radiotherapy for craniopharyngioma: case report

Administration of fractionated doses of irradiation is part of the adjutant therapy for CNS tumours such as craniopharyngiomas and pituitary adenomas. It can maximise cure rates or expand symptom-free period. Among the adverse effects of radiotherapy, the induction of a new tumour within the irradiated field has been frequently described. The precise clinical features that correlate irradiation and oncogenesis are not completely defined, but some authors have suggested that tumors are radiation induced when they are histologically different from the treated ones, arise in greater frequency in irradiated patients than among normal population and tend to occur in younger people with an unusual aggressiveness. In this article, we report a case of a papillary astrocytoma arising in a rather unusual latency period following radiotherapy for craniopharyngioma

Hemorragia de tronco cerebral após remoçäo cirúrgica de cisto aracnóide da fissura silviana: relato de caso / Brainstem hemorrhage after surgical removal of arachnoid cyst of the sylvian fissure: a case report

Os autores relatam um caso de hemorragia de tronco cerebral após craniotomia para ressecçao de grande cisto aracnóide de fissura silviana esquerda. A sintomatologia inicial pré-operatória incluía sinais de hipertensao intracraniana e a tomografia computadorizada mostrava desvio de linha média. Diversos fatores sao discutidos para explicar o sangramento parenquimatoso pós-operatório: edema cerebral, diminuiçao do retorno venoso e de fluxo sanguíneo no lado comprimido. Entretanto a fisiopatologia da hemorragia perenquimatosa em casos como o relatado permanece obscura. uma abordagem cirúrgica mais cutelosa é proposta nesse pacientes com de hipertensao intracraniana.

Shaken baby syndrome (síndrome do bebê chacoalhado): relato de caso / Shaken baby syndrome: report of a case

Os autores relatam o caso de uma lactente de 50 dias de vida que foi trazida ao Pronto Socorro Pediátrico do Hospital de Clínicas da UNICAMP com crises convulsivas. Ao exame apresentava-se sem sinais externos de trauma, hipoativa e com crises convulsivas generalizadas. A fundoscopia evidenciou hemorragia retiniana difusa bilateral. Foi submetida a tomografia de crâneo que mostrou hemorragia inter-hemisférica e "swelling" cerebral. A criança foi internada na UTI pediátrica, mantida sob ventilaçäo assistida e recebendo hidantal porém, apesar do tratamento, evoluiu para óbito três dias depois. Desde o início havia suspeita de maus-tratos, o que foi confirmado um dia após a internaçäo quando o pai relatou que "chacoalhou" a criança porque ela chorava bastante. O presente estudo tem como objetivo ressaltar aspectos sociais, epidemiológicos e a dificuldade diagnóstica desta síndrome que algumas vezes pode ser fatal, como neste caso

Hematoma intracerebral tardio pós-traumatismo craniencefálico por arma de fogo: relato de caso / Delayed intracerebral haematoma after gunshot head injury: case report

Os autores relatam o caso de uma paciente de 25 anos de idade, que foi admitida no Pronto-Socorro do H.C. da UNICAMP. O exame neurológico confirmou Glasgow de 15. Foi feita uma tomografia computadorizada de crânio, que mostrou uma pequena contusäo temporal direita. A paciente ficou internada durante dois dias e recebeu alta sem queixas e com o mesmo Glasgow inicial. Dezessete dias depois, retornou ao Hospital em coma. Uma nova tomografia demonstrou grande hematoma intraparenquimatoso. A mesma faleceu um dia após a internaçäo
