As artérias lenticuloestriadas podem interferir na extensão da ressecção tumoral e sobrevida nos gliomas da ínsula? / Can lenticulostriated arteries interfere with the extent of tumor resection and survival in insula gliomas?

Introdução: Os gliomas são tumores encefálicos e da medula espinhal que se originam nas células gliais e cuja progressão invade o tecido cerebral adjacentee e dentre eles um dos mais desafiadores são localizados no lobo cerebral da ínsula. Estas artérias irrigam estruturas nobres e sua lesão pode produzir danos sensitivos, motores e de linguagem. Objetivo: Descrever o impacto da extensão da ressecção, sobrevida global e dos resultados funcionais após a cirurgia dos gliomas insulares, quando estes tumores estejam ou não envolvidos pelas artérias lenticuloestriadas. Métodos: Revisão integrativa nas plataformas virtuais em português e inglês, buscando AND ou OR dados através dos seguintes descritores "Gliomas da ínsula, Mapeamento cerebral, Artérias lenticuloestriadas". A busca inicial foi baseada no título e/ou resumo. Decididos os trabalhos incluíveis foi realizada a leitura na íntegra dos textos. Ao total foram estudados 55 artigos. Resultados: O lobo da ínsula fica "escondido" pela sobreposição dos lobos frontal, parietal e temporal. Para alcançá-lo pode-se realizar as abordagens transsilviana ou transcortical. Ocorre que ao chegar na ínsula visualiza-se significativa ramificação constituída pelas artérias lenticuloestriadas, cuja manipulação pode determinar déficit neurológico e, ao se aprofundar no córtex insular, depara-se com outras estruturas tão importantes quanto a própria ínsula. O conhecimento anatômico das artérias lenticuloestriadas e suas relações é de fundamental importância para a ressecção de glioma insular, pois o comprometimento delas e da artéria cerebral média podem determinar a isquemia dos núcleos da base e da cápsula interna. Conclusão: O tratamento dos gliomas insulares permanece como grande desafio. Devido à sua localização e possibilidade de desenvolvimento de déficits neurológicos na manipulação cirúrgica é necessário não somente conhecer sua localização topográfica, mas também a íntima relação vascular com as artérias lenticuloestriadas. O envolvimento delas pelo tumor possui implicações na sobrevida e na preservação da função neurológica. O conhecimento detalhado da anatomia da região é fundamental para diminuir complicações que afetem grandemente a qualidade de vida dos pacientes.

Introduction: Gliomas are brain and spinal cord tumors that originate in glial cells and whose progression invades the adjacent brain tissue and among them one of the most challenging are located in the cerebral lobe of the insula. These arteries supply noble structures and their damage can cause sensory, motor and language damage. Objective: To describe the impact of the extent of resection, overall survival and functional results after surgery for insular gliomas, when these tumors are or are not involved by lenticulostriate arteries. Methods: Integrative review on virtual platforms in Portuguese and English, searching for AND or OR data using the following descriptors "Insula gliomas, Brain mapping, Lenticulostriate arteries". The initial search was based on the title and/or abstract. Once the included works were decided, the texts were read in full. In total, 55 articles were studied. Results: The insula lobe is "hidden" by the overlap of the frontal, parietal and temporal lobes. To achieve this, transsylvian or transcortical approaches can be performed. It turns out that when arriving at the insula, a significant branch made up of lenticulostriate arteries is seen, the manipulation of which can cause neurological deficits and, when going deeper into the insular cortex, one comes across other structures as important as the insula itself. Anatomical knowledge of the lenticulostriate arteries and their relationships is of fundamental importance for the resection of insular glioma, as their involvement and that of the middle cerebral artery can determine ischemia of the basal ganglia and internal capsule. Conclusion: The treatment of insular gliomas remains a major challenge. Due to its location and the possibility of developing neurological deficits during surgical manipulation, it is necessary not only to know its topographic location, but also the intimate vascular relationship with the lenticulostriate arteries. Their involvement by the tumor has implications for survival and preservation of neurological function. Detailed knowledge of the region's anatomy is essential to reduce complications that greatly affect patients' quality of life.

É possível prever a mortalidade molecular em meduloblastomas pela análise dos receptores de membrana CD114? / Is it possible to predict molecular mortality in meduloblastomas by analysis of CD114 membrane receptors?

Introdução: Os meduloblastomas são os tumores sólidos mais comuns da infância e classificados em 4 subgrupos moleculares: WNT, SHH, grupo 3 e grupo 4. Muitos estudos buscam desenvolvimento de novos quimioterápicos para os meduloblastomas através da identificação de genes cuja expressão sejam novos alvos moleculares para drogas, como receptores de membrana associados a replicação celular. Objetivo: Avaliar a associação da expressão de CD114 com a mortalidade de pacientes portadores de meduloblastoma. Métodos: Revisão feita colhendo informações publicadas em plataformas virtuais em português e inglês. Inicialmente foi realizada busca por descritores relacionados ao tema - neurocirurgia, oncologia cirúrgica, terapia de alvo molecular e meduloblastoma - e seus equivalentes em inglês - neurosurgery, surgical oncology, molecular targeted therapy e medulloblastoma - com busca AND ou OR, considerando o título e/ou resumo. Após, foram incluídos somente os que tinham maior relação ao tema, e realizada a leitura da íntegra dos textos. Finalmente foram referidos 2 artigos. Resultados: Há diferença na expressão do receptor de membrana CD114 entre o Grupo 3 e os demais grupos moleculares, além de diferença entre o subtipo molecular SHH γ e os subtipos moleculares Grupo 3 α e Grupo 3 ß. Não houve diferença estatisticamente significativa entre os demais grupos e subtipos. Em relação à mortalidade, esta revisão não demonstrou significância estatística na relação entre expressões baixas e elevadas desse gene e a mortalidade. Conclusão: Não há relação direta entre a expressão do receptor de membrana CD114 e a mortalidade em pacientes portadores de meduloblastoma. Entretanto, são necessários estudos adicionais sobre as vias de sinalização intracelulares associadas a esse receptor e ao seu gene, o CSF3R.

Introduction: Medulloblastomas are the most common solid tumors of childhood and classified into 4 molecular subgroups: WNT, SHH, Group 3 and Group 4. Many studies seek to develop new chemotherapy drugs for medulloblastomas by identifying genes whose expression is new molecular targets for drugs, such as membrane receptors associated with cell replication. Objective: To evaluate the association of CD114 expression with mortality in patients with medulloblastoma. Methods: Review carried out collecting information published on virtual platforms in Portuguese and English. Initially, a search was carried out for descriptors related to the topic - neurosurgery, surgical oncology, molecular targeted therapy and medulloblastoma, with AND or OR search, considering the title and/or summary. Afterwards, only those that were most related to the topic were included, and the texts read in full. Finally, 23 articles were referred. Results: There is a difference in the expression of the CD114 membrane receptor between Group 3 and the other molecular groups, in addition to a difference between the SHH γ molecular subtype and the Group 3 α and Group 3 ß molecular subtypes. There was no statistically significant difference between the other groups and subtypes. Regarding mortality, this review did not demonstrate statistical significance in the relationship between low and high expressions of this gene and mortality. Conclusion: There is no direct relationship between the expression of the CD114 membrane receptor and mortality in patients with medulloblastoma. However, additional studies are needed on the intracellular signaling pathways associated with this receptor and its gene, CSF3R.

Evaluation of progesterone receptor expression in low- and high-grade astrocytomas.

OBJECTIVE: Gliomas are tumors originating from glial cells. Gliomas are the most common primary neoplasms of the central nervous system, with astrocytomas being the most prevalent glioma subtype. Progesterone regulates several reproductive processes, such as ovulation and sexual behavior, and influences neuronal excitability, learning, and the neoplastic proliferation of glial cells. Progesterone functions mainly by interacting with intracellular progesterone receptors to modify the expression of the genes involved in cell proliferation, angiogenesis, and epidermal growth factor production. As not many studies on the hormone receptors in glial tumors have been reported, the objective of this study was to evaluate the expression of these proteins in astrocytomas and to determine whether their expression levels vary according to the tumor grade. METHODS: This was a retrospective study using glial tumor paraffin blocks obtained from the São Marcos Hospital Pathology Department archives. Forty cases were divided equally into two groups, based on histological types and the World Health Organization criteria (low- and high-grade tumors). Progesterone receptor expression was analyzed by immunohistochemistry. The data were statistically analyzed using the Mann-Whitney U test and Spearman's correlation coefficient; results with p<0.05 were considered statistically significant. RESULTS: There were no statistically significant differences between the mean nuclear progesterone receptor expression of low-grade (0.1495) and high-grade (0.0937) astrocytomas (p=0.2). CONCLUSION: Progesterone receptors are present in both low- and high-grade gliomas; however, there is no significant difference in the levels of progesterone receptor expression between the tumor grades.

Association between Single Nucleotide Polymorphisms and Glioma Risk: A Systematic Literature Review.

This study aimed to determine the main single nucleotide polymorphisms (SNPs) that are associated with an increased or decreased risk of glioma development in healthy individuals. We conducted a systematic review of the articles published in English on the PUBMED database between January 2008 and December 2017. Our search resulted in a total of 743 articles; however, only 56 were included in this review. A total of 148 polymorphisms were found, which involved 64 different genes. The polymorphisms that were most associated with an increased risk of glioma development were polymorphic variants rs179782, rs13181, and rs3791679 of the genes XRCC1, ERCC2, and EFEMP1, respectively.

Basilar invagination associated with chiari malformation type I: A literature review.

Basilar invagination (BI) and Chiari malformation type I (CM-I) are very important anomalies that introduce instability and compression in the occipitocervical transition region and have complex clinical characteristics. These anomalies vary according to the affected structures. The present study revises current knowledge regarding the anatomy, anatomo-physiology, clinical manifestations, and radiological findings of these entities and the associated surgical treatment approaches. A bibliographic survey was performed through a search in the Medline, PubMed, SciELO, Science and LILACS databases. When associated, these craniovertebral malformations result in neurological deficits due to neural parenchyma compression; however, the presence of microtraumas due to repetitive lesions caused by the bulb and cervical marrow instability has been highlighted as a determinant dysfunction. Surgical treatment is controversial and has many technical variations. Surgery is also challenging due to the complex anatomical characteristics and biomechanics of this region. Nevertheless, advances have been achieved in our understanding of related mechanisms, and compression and atlantoaxial instability are considered key elements when selecting the surgical approach.

Importance of the First Coil in the Embolization of Intracranial Aneurysms : A Case Control Study.

PURPOSE: Endovascular therapy for the treatment of cerebral aneurysms has a higher incidence of rebleeding and a lower occlusion rate than microsurgical clipping. This study investigated whether first coil volume packing density (1st VPD) and first loop diameter of the first coil (1st LD) are associated with recanalization after endovascular coiling. METHODS: The study included 174 initial saccular aneurysm cases from 2010 to 2015. Between the recanalization and non-recanalization groups, we compared age, sex, aneurysm location, rupture occurrence, shape, maximum aneurysm size, neck width, dome-to-neck ratio, aneurysm volume, coil volume, VPD, 1st VPD, 1st LD, relation of the first loop diameter of the first coil and the maximum aneurysm size (RLAS), types of assistance techniques, and the Raymond scale score at initial and follow-up angiography. RESULTS: Recanalization occurred in 41 cases (23.6%). The factors associated with recanalization were irregular shape, maximum aneurysm size, neck width, dome-to-neck ratio, aneurysm volume, VPD, 1st VPD and 1st LD smaller than the maximum aneurysm size. The cut-off values for aneurysmal recanalization were 92%, 11% and 37% for RLAS, 1st VPD and VPD, respectively. CONCLUSION: The 1st VPD and 1st LD were associated with aneurysmal recanalization after embolization. These factors provide a helpful index for coil programming.

Embryonic Tumor with Abundant Neuroepithelium and True Rosettes (ETANTR): Case Report and Literature Review

The embryonal tumor with abundant neuropil and true rosettes (ETANTR) is an extremely rare variant of the primitive neuroectodermal tumor (PNET). About 80 cases have been reported since its first description in the literature, in 2000. The ETANTR occurs in very young patients, especially children under 6 years of age. It is found mainly in the cerebral cortex. Headache, focal neurological signs, seizures, increased head circumference and psychomotor developmental delay are the most frequent symptoms of ETANTR. Histologically, it displays the features of an ependymoblastoma and a neuroblastoma, showing areas of neuroepithelium fibrillar rosettes with ependymoblastic zones and interposed undifferentiated neuroepithelial cells. The ETANTR is distinguishable from other embryonal tumors due to the abundance of neuroepithelium. Genetic studies have demonstrated the presence of polysomy of chromosome 2 and chromosome 19q13.42 amplification. This is an extremely aggressive tumor with a mean survival ranging from 9 to 48 months. We present the first report in Brazil, published in indexed literature, of an ETANTR case involving a young child.

O tumor embrionário com neurópilo abundante e rosetas verdadeiras (TENARV) é uma variante muito rara do tumor neuroectodérmico primitivo (TNEP), com cerca de 80 casos publicados desde a sua primeira descrição na literatura, em 2000. O TENARV ocorre em pacientes muito jovens, especialmente crianças abaixo de 6 anos de idade, atingindo principalmente o córtex cerebral. Cefaleia, sinais focais, crise convulsiva, aumento do perímetro cefálico e atraso do desenvolvimento psicomotor são os sintomas mais frequentes da TENARV. Histologicamente, este tipo de tumor apresenta as características combinadas de um ependimoblastoma e um neuroblastoma, demonstrando áreas de neuroepitélio fibrilar com rosetas ependimoblásticas de permeio e zonas de células neuroepiteliais indiferenciadas. O TENARV é distinguível de outros tumores embrionários pela abundância de neuroepitélio. Estudos genéticos demonstram a presença de polissomia do cromossomo 2 e amplificação do cromossomo 19q13.42. Trata-se de um tumor extremamente agressivo, com sobrevida média entre 9 e 48 meses. Apresentamos o primeiro relato brasileiro, publicado em literatura indexada, de um caso de TENARV acometendo uma criança jovem.

OBJETIVO: Investigar as alterações histopatológicas produzidas por um modelo de trauma craniano fechado por queda de peso em ratos. MÉTODOS: Utilizando uma plataforma para produção de lesão craniana fechada controlada por queda de peso com energia pré-definida e conhecida, 25 ratos Wistar machos (Rattus norvegicus albinus) foram divididos em cinco grupos iguais que receberam níveis diferentes de energia de impacto craniano: G1, G2, G3 e G4 com 0,234J, 0,5J, 0,762J e 1J respectivamente e G5 (Sham). Sob analgesia, cada grupo teve seus encéfalos coletados e processados para análise histopatológica por microscopia óptica convencional. RESULTADOS: Houve maior número de neurônios lesados em animais do grupo 4, mas morte neuronal também pôde ser constatada nos animais do grupo 5. Hemorragias parenquimatosas foram mais frequentes nos animais do grupo 4 e o inchaço cerebral citotóxico e congestão vascular foram mais intensos neste grupo. CONCLUSÃO: Os achados à análise histopatológica permitem observar alterações típicas do trauma craniano e estas guardaram proporção direta com a energia do impacto.

Resultados tardios da descompressão microvascular do nervo facial pela artéria vertebral / Long-term outcomes of facial nerve microvascular decompression by vertebral artery

Espasmos faciais constituem afecção rara, caracterizada por contrações assimétricas, involuntárias e paroxísticas da musculatura facial. Frequentemente são de acometimento unilateral e levam a situação desconfortável e prejudicial à qualidade de vida dos pacientes. Na maioria das vezes, o quadro inicia-se gradualmente no músculo orbicular dos olhos, seguindo-se por acometimento do andar inferior da face ipsilateralmente. Os espasmos são causados por compressão vascular, mais comumente provocada pela presença da artéria cerebelosa póstero-inferior (PICA) ou da artéria cerebelosa antero-inferior (AICA) (sendo mais raro o envolvimento da artéria vertebral) sobre a raiz do nervo facial, na REZ (Root Entry Zone). Injeção de toxina botulínica no músculo facial envolvido é uma opção terapêutica medicamentosa, no entanto possui benefícios transitórios ao longo da terapia. A descompressão microvascular é um tratamento efetivo, com baixas taxas de complicação. Descreve-se o caso de um paciente de 65 anos portador de contrações involuntárias e esporádicas da musculatura orbicular do olho esquerdo de caráter insidioso e progressivo. Optou-se por microcirurgia descompressiva com interposição de teflon entre artéria vertebral esquerda e o nervo facial na fossa posterior, com significativa melhora clínica, e regressão progressiva dos espasmos até sua completa remissão.

Facial spasm is a rare disease characterized by asymmetriccontractions and involuntary paroxysmal activity offacial muscles. It is often unilateral disease and leadsto an uncomfortable and injurious situation that affectspatients’ quality of life. Most often, it begins gradually inthe orbicularis oculi muscle, followed by involvement of theipsilateral inferior face . The spasms are usually causedby PICA and AICA vascular compression (vertebral arterycompression is more rare) of the facial nerve root, in itsentry zone. Botulinum toxin injection in the involved facialmuscle is a treatment option, however has transient benefitsduring the therapy. Microvascular decompression is aneffective treatment, with low complication rates. We reporta case of a 65-year-old patient with sporadic involuntarycontractions of left orbicular muscle , with an insidious andprogressive character. Microsurgical decompression withTeflon interposition between the left vertebral artery and thefacial nerve in the posterior fossa was performed. There wasa significant clinical improvement, with progressive decreaseof the spasms until complete remission.

Lesão cerebral traumática: parâmetros clínicos e patológicos em um modelo experimental de queda de peso / Traumatic brain injury: clinical and pathological parameters in an experimental weightdrop model

PURPOSE: To investigate the function of an experimental cranium trauma model in rats. METHODS: The equipment, already described in the literature and under discreet adaptations, is composed by a platform that produces closed head impact controlled by weight drop with pre-defined and known energy. 25 Wistar male rats (Rattus norvegicus albinus) were divided into five equal groups that received different quantities of cranial impact energy: G1, G2, G3 and G4 with 0,234J, 0,5J, 0,762J and 1J respectively and G5 (Sham). Under intense analgesia, each group was evaluated clinically in a sequence of intervals and had their encephalon removed for pathologic analysis.
