Injuries are classified as diffuse (diffuse axonal injury and brain swelling) or focal (cerebral contusion [CCo], epidural hematoma, and acute subdural hematoma). Among all TBIs, CCos are the most frequent focal lesion, and treatment modalities are many. Hematoma evacuation using large craniotomies has been well described in the literature. The main goal of the present study is to discuss the advantages of minimally invasive approaches for the treatment of CCos, regarding operative time, blood loss, and postoperative tomographic results. Methods An integrative literature review was conducted on the SciELO, LILACS, and PubMed databases. Seven case reports were included in the present study. Retrospective data collection was performed, analyzing gender, age, Glasgow coma scale score on hospital admission, surgical approach, and postoperative (tomographic) results. Results The minimally invasive keyhole approach was used in seven patients with CCos. The supraorbital approach (n = 5) was performed for frontal lobe contusions, and the minipterional approach (n = 2) was performed for temporal lobe contusions. All cases had adequate hematoma evacuation, confirmed by postoperative computed tomography scans.

Objectives Clinical outcome of fetuses undergoing intrauterine MMC repair by the Peralta mini-hysterotomy. Monitor the reduction of Arnold-Chiari II secondary to MMC, reduction of hydrocephalus and also motor development in these children. Methods Descriptive study of 26 cases with intrauterine MMC repair by mini-hysterotomy, or Peralta technique, performed at the IECPN from December 2017 to February 2020. Results Between December 2017 and February 2020, 26 pregnant women with children with MMC were operated on using Peralta technique. Fetuses were born at an average gestational age of 34.2 weeks and 8% were born before 30 weeks of gestation. The average birth weight was 2096g. It was possible to observe a significant reduction in the occurrence of Arnold-Chiari II in these patients, as well as an evident improvement in motor function in the neurological examination of these babies at the end of the first month of life, where 20 of 23 babies had active movement in the lower limbs. Discussion This study demonstrates the correction of fetal MMC through a mini-hysterotomy of 2.5 to 3.5 cm, developed in order to reduce maternal and fetal mortality. This mini-hysterotomy technique is not a minimally invasive procedure, as it is based on open surgery for the treatment of fetal MMC, as recommended by the Management of Myelomeningocele Study (MOMS).","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136294351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors report a case of AO in a 9-year-old female patient presenting with 5th and 7th cranial nerve palsy. Prior pathological history included resection of an expansile nodule in the left temporal bone. Conventional radiological examination and computed tomography (CT) of the skull revealed an osteoblastic lesion arising in the petrous portion of the left temporal bone, measuring 5.2 cm in the largest dimension. The patient was subjected to partial surgical resection of the process. Microscopy revealed a primary neoplastic bone composed of numerous epithelioid round osteoblasts disposed in solid sheets and with mild atypia, large eosinophilic cytoplasm, and an eccentric, ovoid nucleus. The process exhibited loose stroma, low mitotic index, osteoid formation, and a few osteoclast-like multinucleated giant cells. The diagnosis of AO was thus established. After 5 months of clinical follow-up, the patient is asymptomatic, without evidence of tumoral growth on CT scans.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"427 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136294350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is an integrative literature review guided by the guiding question: “Do changes in blood glucose levels or plasma sodium concentration influence in-hospital morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage?”. The search for articles was performed on the PubMed platform, limiting the selection to works published in English in the period from 2017 to 2022. The results found demonstrate that the role of sodium ions in changes in the prognosis of patients is complex, with hypernatremia being the main factor described to worse outcomes. In contrast, the part of hyponatremia is controversial and may not have prognostic value, and serum sodium concentration is increasingly an important item to be evaluated in patients with aSAH. As for glucose, the variability of this substrate, both hyperglycemia and hypoglycemia, may be correlated with in-hospital and long-term mortality in patients with aSAH. Thus, the present study concludes that changes in blood glucose values and plasma sodium concentration influence the in-hospital morbidity and mortality of patients with aSAH. However, it is emphasized that the analysis of the independent influence of each of the related predictors must be done with caution due to the heterogeneity of the results found.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136294352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Review of previous studies from 1927 to 2021, from basic and translational research using human and animal ES tissue or cells, as well as previous reviews about the subject. The present article is divided into three parts. In this first part, we review the microsurgical anatomy and physiology of the ES. Results The ES is a structure situated in the inner ear, together with the cochlea, the vestibular system, and other structures. Differently from its adjacent structures, the ES does not have a specialized epithelium; instead, it has mitochondria-rich cells and ribosomal-rich cells, which are responsible for ionic transportation and secretory activity. Apart from these functions, the ES is also responsible for homeostasis regulation of the inner ear, endolymphatic fluid volume control, immune response, elimination of inner ear cellular debris and floating otoconia, regulation of membranous labyrinth pressure, acid/basic transport, and secretion of substances. Its anatomy is not very variable, since in most studies no more than 20mm separates the location of the ES in the samples, in any direction. Conclusion The human ES has vital functions in the inner ear, and its anatomy is rarely variable. Knowing that, and the importance of this area for neurosurgery, the present study elucidates the exact location of the ES and the lost functions that a lesion in this structure must cause.","PeriodicalId":42205,"journal":{"name":"Brazilian Neurosurgery-Arquivos Brasileiros de Neurocirurgia","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135044459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results Among the 65 patients who underwent biopsy, 42 were male, and 23 were female. The mean age was 53.1 years.
