ABSTRACT

Luigi Luciani (1840-1919) was an illustrious Italian citizen and physiologist whose research scope covered mainly cardiovascular subjects, the nervous system, and fasting. He published in 1891 a modern landmark of the study of cerebellar physiology - "Il cervelletto: nuovistudi di normal and pathología physiology" / "The cerebellum: new studies on normal and pathological physiology." In his experiment, a dog survived after cerebellectomy, reporting a triad of symptoms (asthenia, atonia, and astasia). In this way, the eminent neurophysiologist improved the operative technique and sterile processes to redirect the issue of cerebellar symptoms. Luciani died at age 78, a hundred years ago, and left mainly the understanding of the role of the cerebellum in regulating postural tone and muscle strength, which represented a step forward in understanding cerebellar motor physiology. In recent decades, cognitive / affective function has been added to the cerebellar motor, and there has also been a better understanding of cerebellar circuits.


Luigi Luciani (1840-1919) foi um ilustre cidadão e fisiologista italiano, cujo escopo de pesquisa abrangia principalmente assuntos cardiovasculares, sistema nervoso e jejum. Ele publicou em 1891 um marco moderno do estudo da fisiologia do cerebelo - "Il cervelletto: nuovistudi di fisiologia normale and patologica" / "O cerebelo: novos estudos sobre fisiologia normal e patológica". Em seu experimento, um cão sobreviveu após a cerebelectomia, com o relatório de uma tríade de sintomas (astenia, atonia e astasia). Dessa maneira, o eminente neurofisiologista aprimorou a técnica operatória e os processos estéreis para redirecionar a questão dos sintomas cerebelares. Luciani morreu aos 78 anos, cem anos atrás, e deixou principalmente a compreensão do papel do cerebelo na regulação do tônus postural e da força muscular, o que representou um passo adiante na compreensão da fisiologia motora cerebelar. Nas últimas décadas, a função cognitivo / afetiva foi adicionada à motora cerebelar e, também, houve uma melhor compreensão dos circuitos do cerebelo.

ABSTRACT

Organic causes of astasia or asterixis have been described in the literature. However, concurrent unilateral manifestation of the two symptoms is extremely rare. We report two cases presenting with astasia and asterixis due to infarcts involving the ventrolateral nucleus of the left thalamus. Acute onset of astasia or asterixis in patients without significant metabolic disorder should alert the clinician on the possibility of acute stroke involving the thalamus.
