ABSTRACT

Ludwig van Beethoven, the great composer, born 250 years ago, had several health problems and a progressive hearing loss. Gastrointestinal symptoms prevailed among his physical complaints, but there were also frequent headaches, eye pain, and polyarthralgia. Likewise, there are many reports about his alcohol intake and frequent walks. There were also peculiar behavioral and awkward physical aspects of the famous composer. All may take part as a determinant for the communicative aspects of his music. Spite Beethoven's corporal structure could be considered just a developmental variant, it can also be congenitally related to many bone-nervous abnormalities such as craniovertebral junction malformation with interference in the Genius' health. In reality, it is almost impossible to cover Beethoven's entire health problem with just one underlying disease. Most likely, he had comorbidities, one of which, although not fatal, was that related to abnormalities in the development of the skull and cervical spine worsened by a baseline autoimmune disorders that injured joints, and maybe even the VIII cranial nerve and inner ear.


Ludwig van Beethoven, o grande compositor, nascido há 250 anos, teve vários problemas de saúde e uma perda auditiva progressiva. Os sintomas gastrointestinais prevaleceram entre suas queixas físicas, mas também houve frequentes episódios de cefaleia, dores nos olhos e poliartralgia. Da mesma forma, há muitos relatos sobre sua ingestão de álcool e caminhadas frequentes. Havia também aspectos físicos peculiares e estranhos do famoso compositor. Todos podem tomar parte como um determinante para os aspectos comunicativos de sua música. Apesar da estrutura corporal de Beethoven poder ser considerada apenas uma variante de desenvolvimento, pode também estar relacionada a algumas anormalidades ósseo- neural, tais como a malformação da junção craniovertebral com interferência na saúde do Gênio. Na realidade, é quase impossível cobrir todo o problema de saúde de Beethoven com apenas uma doença subjacente. Muito provavelmente, ele tinha comorbidades, uma das quais, embora não fatal, era aquela relacionada a anormalidades no desenvolvimento do crânio e da coluna cervical agravadas por uma desordem auto-imune de base que lesionava as articulações, e talvez até o VIII nervo craniano e o ouvido interno.

ABSTRACT

Abstract Objective: The present study aims to perform a reproducibility study of the clivus-canal angle (CCA), Welcker's basal angle (WBA), and the distance from the odontoid process to Chamberlain's line (DOCL) on magnetic resonance imaging (MRI). Materials and Methods: Two medical students and two radiologists respectively evaluated 100 and 50 consecutive MRI scans of adult skulls, selected randomly. Each examiner, working independently and blinded to the previous results, performed readings for each patient on two different occasions. Measurements were performed in T1-weighted sequences acquired in the midsagittal plane. The levels of intraobserver reproducibility and interobserver agreement were evaluated by calculating the intraclass correlation coefficients (ICCs) and the corresponding 95% confidence intervals. Results: The mean values obtained by the examiners were 150° for the CCA, 130° for the WBA, and 2.5 mm for the DOCL. The ICC for interobserver agreement was 0.980, 0.935, and 0.967, for the CCA, WBA, and DOCL, respectively, for the students, compared with 0.977, 0.941, and 0.982, respectively, for the radiologists, and 0.980, 0.992, and 0.990, respectively, for all of the examiners together. In the analysis of intraobserver agreement, the ICC ranged from 0.929 to 0.959 for the CCA, from 0.918 to 0.964 for the WBA, and from 0.918 to 0.981 for the DOCL. Conclusion: The measurement of the CCA, WBA, and DOCL appears to show excellent intraobserver reproducibility and interobserver agreement on MRI.


Resumo Objetivo: Realizar um estudo de reprodutibilidade do ângulo clivocanal (ACC), ângulo basal de Welcker (ABW) e distância do odontoide à linha de Chamberlain (DOLC) em ressonância magnética (RM). Materiais e Métodos: Quatro examinadores, dois graduandos de medicina e dois radiologistas, avaliaram, respectivamente, 100 e 50 indivíduos adultos submetidos a RM de crânio, consecutiva e aleatoriamente. Cada um realizou duas leituras para cada paciente em diferentes ocasiões, de forma cega e independente. As análises de concordância intraobservador e interobservador foram realizadas pelo coeficiente de correlação intraclasse (CCI), com intervalo de confiança de 95%. Resultados: As medidas médias, considerando todos os examinadores, foram: ACC = 150°, ABW = 130°, DOLC = 2,5 mm. A análise interobservador entre os estudantes revelou CCI de 0,980, 0,935 e 0,967 para ACC, ABW e DOLC, respectivamente, e para os radiologistas, CCI de 0,977, 0,941 e 0,982, respectivamente. A análise interobservador entre estudantes e radiologistas revelou CCI de 0,980, 0,992 e 0,990, respectivamente. Em relação à análise intraobservador, as medidas do ACC tiveram CCI variando entre 0,929 e 0,959, ABW entre 0,918 e 0,964 e DOLC entre 0,918 e 0,981. Conclusão: ACC, ABW e DOLC obtiveram excelentes reprodutibilidades intraobservador e interobservador na RM.

ABSTRACT

The high prevalence of craniovertebral junction malformation in Northeastern Brazil is historically associated with brachycephalic biotype (flat head), also common in this region. It has been postulated that this trait was introduced to this region by the Dutch during the colonial period in Brazil's history. Based on the confrontation of this paradigm against some historical facts, the authors concluded that the brachycephalic phenotype was inherited from prehistoric ancestors (Amerindians) who were already living in this region when white European men arrived.

A alta prevalência de malformação da junção craniovertebral no Nordeste do Brasil é historicamente associada ao biótipo braquicefálico (cabeça chata), também comum nessa região. Postula-se que essa característica tenha sido introduzida na região pelos holandeses durante o período colonial da história do Brasil. Com base na confrontação desse paradigma com alguns fatos históricos, os autores concluem que o fenótipo braquicefálico foi herdado de ancestrais pré-históricos (ameríndios) que já habitavam a região no momento da chegada do homem branco europeu.
