Five-Year Longitudinal Cohort Study Determines the Critical Intervals for Periodic Audiometric Testing Based on 5070 Tests of Metallurgical Workers Exposed and Nonexposed to Noise

Ear and Hearing (2021)

Vagner Antônio Rodrigues da Silva Alexandre Caixeta Guimarães Joel Lavinsky Henrique Furlan Pauna Alexandre Scalli Mathias Duarte

To compare the progression of 3-, 4-, and 6-kHz thresholds (pure-tone average) over 5 years and determine the most critical period for occupational risk among workers exposed and nonexposed to noise.Metallurgical workers were divided into 2 groups: noise-exposed and non-noise-exposed groups. The 6 initial audiometric tests of each worker were analyzed as baseline test and annual tests 1 to 5.A total of 845 workers were included, 748 in the noise-exposed group and 97 in the non-noise-exposed group, resulting in 5070 tests analyzed. The nonexposed group showed no significant difference in the mean pure-tone averages between any of the annual tests in either ear. In the exposed group, a significant difference was observed in mean pure-tone averages between baseline and Test1 (p = 0.001 right ear; p = 0.001 left ear), between Test3 and Test4 (p = 0.002 right ear; p = 0.005 left ear), and between Test4 and Test5 (p = 0.003 right ear; p = 0.001 left ear). There was no difference between Test1 and Test2 or between Test2 and Test3 in either ear.The progression of pure-tone averages at 3, 4, and 6 kHz differed between workers exposed and nonexposed to noise. Noise-exposed workers had a significant progressive worsening of audiometric thresholds after 3 years of employment. This study identified, in an unprecedented way, two critical periods of noise exposure: in the first year and after the third year of employment in a noisy environment.

What is known about superior semicircular canal dehiscence syndrome

BioSCIENCE (2024)

Alícia Batista de Almeida Barbosa Gustavo Henrique Tomasi José Fernando Polansky Joel Lavinsky Rafaela Fernandes Gonçalves

Introdução: A origem da síndrome foi levantada através do estudo de tomografias computadorizadas onde os sintomas eram acompanhados de falha na cobertura óssea do canal semicircular superior, na fossa craniana média, próximo à dura-máter. Essa doença ainda não é de conhecimento da maioria dos médicos. Objetivo: Atualizar o conhecimento sobre ela para despertar a possibilidade de sua existência durante atendimento médico. Método: Revisão narrativa feita nas plataformas Pubmed e Scielo visando artigos ao tema, incluindo relatos de casos, estudos, revisões e metanálises publicados entre 1998 e 2023. Foram incluídos artigos em inglês, português e espanhol. Os descritores usados foram “superior canal dehiscence syndrome”, “superior canal dehiscence” e “síndrome da deiscência do canal semicircular superior”. Resultado: Foram analisados 47 artigos. Conclusão: O entendimento dessa síndrome é complexo e pouco conhecido, e aprimoramento das estratégias de tratamento requerem abordagem multidisciplinar com investigação contínua na intenção de oferecer melhor qualidade de vida ao portador. Tentativas evolutivas na orientação terapêutica até que se tenha confirmação por evidências de qual é melhor forma de tratamento, é o que na atualidade deve ser feito.

What a Neurosurgeon Should Know About the Endolymphatic Sac: Part 1–Anatomy and Physiology

Arquivos Brasileiros de Neurocirurgia Brazilian Neurosurgery (2023)

Marco Antônio Schlindwein Vaz Jander Moreira Monteiro Francisco Luiz Souza Braga Joel Lavinsky Giuseppe Casella Santis

Abstract Objective To describe the microsurgical anatomy and the physiology of the endolymphatic sac (ES) that a neurosurgeon should know. 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.

Neurosurgical Management of Skull Base Epidermoid Tumors in Children

Cureus (2022)

Marco Antônio Schlindwein Vaz Joel Lavinsky Ricardo Ventura Santos Francisco Pantoja Braga Paola Maria Brolin Santis Isolan

Epidermoid tumors (ET) are congenital and benign tumors that develop from de ectoderm during neurogenesis. In the skull base, these lesions can insinuate themselves into several intracranial compartments by filling the subarachnoid space, and possibly affecting some important structures, like the brainstem, cerebellopontine angle, the pituitary in the middle fossa, and others. In the pediatrics skull base tumors, the ET represents 7-9%, being very rare. The surgical perspective of these cases is dependent on the extension of the resection. We presented two cases of total and near-total resection of ETs in the pediatric skull base, with successful outcomes.
