Would Francisco Soca have been the first to relate toe phenomenon as pyramidal disorders?

INTRODUCTION: The Uruguayan physician Francisco Soca, who specialized in neurology in Jean-Martin Charcot's clinic, defended a thesis at the Paris Faculty of Medicine in 1888 on Friedreich's ataxia in eleven patients. In this work he described the presence of toe phenomenon. OBJECTIVE: This historical note presents a toe sign described by the Soca eight years before Babinski's classic description. DISCUSSION: In the late 1800s Soca completed a specialization in neurology at the service run by Charcot in Paris. He defended an important thesis in 1888 assessing data from 11 Friedreich's ataxia. In his thesis, Soca also described the toe phenomenon and the presence of structural changes in the feet of these patients that were not described in the Friedreich study published in 1863. CONCLUSION: The Soca's thesis contained the description of toe extension associated with pyramidal tract lesions, eight years later described and further immortalized as Babinski's sign. Therefore, Soca had already publicized this sign as being representative of a pyramidal dysfunction before Babinski or any other neurologist.

Paraparesia espástica por HTLV-I: 20 años después. A propósito de un caso / Spastic paraparesis by HTLV-I: 20 years later. About a case / Paraparesia espástica pelo HTLV-I: 20 anos depois. Sobre um caso

Resumen: Se describe un caso de paraparesia espástica asociada al retrovirus HTLV-I, en una paciente de 34 años, cuyo diagnóstico se realizó 17 años después del inicio de su enfermedad. El mismo se obtuvo mediante la determinación de anticuerpos en sangre y líquido cefalorraquídeo. En la literatura nacional existen solo dos casos publicados previamente. El objetivo de la presentación del caso es recordar las principales características epidemiológicas, clínicas y paraclínicas de dicha patología, así como restablecer la importancia de considerar al HTLV-Ia la hora de búsqueda etiológica de una mielopatía crónica, y mantener los controles en sangre de donantes y hemoderivados para eliminar una de las principales vías de contagio.

Abstract: A case of spastic paraparesis associated with HTLV-I retrovirus was described in a 34-year-old patient whose diagnosis was made 17 years after the onset of his disease. It was obtained by determining antibodies in blood and cerebrospinal fluid. In the national literature there are only two previously published cases. The objective of the presentation of the case is to recall the main epidemiological, clinical and paraclinical characteristics of said pathology, as well as to re-establish the importance of considering the HTLV-Ia the etiological search time of a chronic myelopathy, and to maintain the blood controls of donors and blood products to eliminate one of the main routes of infection.
