"Stat Rosa Pristina Nomine, Nomina Nuda Tenemus": The Many Syndromes, Diseases, and Anatomic Structures Bearing Jean-Martin Charcot's Name.

The sheer magnitude of Jean-Martin Charcot's contributions to neurology, pathology, psychiatry, and internal medicine has allowed for the common usage of eponyms bearing the master's name in recognition of his work. However, these are so numerous that confusion has naturally arisen concerning the exact nature of each eponym, allowing for different specialists to refer to completely different ailments or symptoms, while using the very same expression. Previous compilations of his eponyms were often incomplete. Therefore, the authors aimed to bring some clarification into the nature and origin of each known eponym with Charcot's name.

The Devil Is in the Details: Neurological Diseases Presenting as Religious Hallucinations in Two Literary Works.

Few authors in the Western literature have acquired such a monumental reputation as Thomas Mann and Fyodor Dostoyevsky; although with different backgrounds and aesthetic peculiarities, their writings converge thematically in their frequent relationship with disease. From Dostoyevsky's struggle with epilepsy to Mann's descriptions of tuberculosis and cholera, many are the examples found in their body of work describing medical afflictions. One noteworthy similarity in their works is the presence of hallucinations with Mephistopheles-like devilish entities, possibly caused by neurological diseases: in Mann's case, concerning the main character of Doctor Faustus, caused by neurosyphilis, while for Dostoyevsky, concerning one of the titular Brothers Karamazov, by delirium tremens. In both cases, the authors leave room for ambiguity, with the characters themselves casting doubts on whether their experiences were indeed caused by their disease or by an actual supernatural being. In this, we may find an interesting intersection between neurology and the literature.

Pioneers in the cisterna magna puncture.

At the beginning of the 20th century, cerebrospinal fluid (CSF) collection and analysis emerged as a promising aid in the diagnosis of diseases of the central nervous system. It was obtained through the established procedure of lumbar puncture, described by Heinrich Quinke in 1891. The search for an alternative way to gather the CSF emerged in animal research, highlighting the cisterna magna as a promising source, with relative safety when performed by someone trained. Described initially and in detail by James Ayer in 1920, the procedure was widely adopted by neurologists and psychiatrists at the time, featuring its multiple advantages and clinical applications. After a period of great procedure use and exponential data collection, its complications and risks relegated the puncture of the cisterna magna as an alternative route that causes fear and fascination in modern Neurology.

Resumo No início do século XX, a coleta e análise do líquido cefalorraquidiano (LCR) despontavam como um promissor auxílio no diagnóstico das doenças do sistema nervoso central. Sua obtenção se dava através do consagrado procedimento de punção lombar, descrito por Heinrich Quinke em 1891. A busca por uma via alternativa na obtenção do LCR ganhou destaque nas pesquisas animais, destacando-se na cisterna magna promissora fonte, com relativa segurança quando executada por alguém treinado. Descrito inicialmente e de maneira pormenorizada por James Ayer em 1920, o procedimento foi amplamente adotado por neurologistas e psiquiatras à época, com destaque para suas múltiplas vantagens e aplicações clínicas. Após um período de grande uso do procedimento e exponencial obtenção de dados, suas complicações e riscos relegaram a punção da cisterna magna como via alternativa que causa medo e fascínio na Neurologia moderna.

A concise historical perspective of the area postrema structure and function / Uma perspectiva histórica concisa da estrutura e função da área postrema

ABSTRACT First described by Retzius at the end of the 19th century, the structure in the posterior medulla oblongata, then named area postrema, underwent an intense investigation into its function in the decades that followed. Findings, mainly in animal studies, have partially elucidated its role as an emetic center in the central nervous system. In the second half of the 20th century, this function was associated with reports of syndromes characterized by uncontrollable nausea and vomiting related to structural damage in the area postrema, mainly in the context of demyelinating diseases. At the beginning of the 21st century, the so-called area postrema syndrome has been consolidated as a diagnostic factor in diseases related to the spectrum of neuromyelitis optica, more than 100 years after its first description.

RESUMO Descrita pela primeira vez por Retzius no final do século XIX, a estrutura na medula oblonga posterior, então nomeada de área postrema, passou por intensa investigação quanto à sua função nas décadas seguintes. Achados sobretudo em estudos com animais elucidaram parcialmente sua função como centro emético no sistema nervoso central. Na segunda metade do século XX, tal função foi associada a relatos de síndromes caracterizadas por náuseas e vômitos incoercíveis relacionadas a lesões estruturais na área postrema, principalmente no contexto das doenças desmielinizantes. Já no início do século XXI, a então chamada síndrome da área postrema se consolida como fator diagnóstico nas doenças relacionadas ao espectro da neuromielite óptica, mais de 100 anos sua primeira descrição.

Endovascular Treatment of a Dural Arteriovenous Fistula after Cerebral Sinovenous Thrombosis in a Child.

BACKGROUND: Dural arteriovenous fistula (DAVF) is rare in children. Development theories postulate a response to cerebral sinovenous thrombosis (CSVT) or to venous hypertension. The symptoms are highly nonspecific and depend on lesion location. Standard treatment of thrombosis is based on antithrombotic therapy, while the main therapy for DAVF is embolization. CASE REPORT: An 8-year-old boy presented with headache was diagnosed with CSVT and treated with anticoagulant. He developed tinnitus, mental confusion, and lowering of consciousness. Magnetic resonance imaging showed a DAVF draining through a single stenotic venous sinus. Successful endovascular treatment was performed with arterial embolization of multiple feeders and stent and balloon sinus angioplasty. CONCLUSION: Risk factors associated with sinus thrombosis must be always investigated; endovascular treatment is safe and reasonable in a clinical deterioration scenario.
