ABSTRACT

Introducción: El infarto medular es una entidad infrecuente y con elevada morbilidad. El diag-nóstico puede resultar difícil y el tratamiento óptimo sigue siendo controvertido. Existen pocasseries de casos publicadas.Métodos: Estudio retrospectivo de infarto medular en un hospital terciario desde 1999 a 2020.Se evaluaron la etiología, las características clínicas, radiológicas, terapéuticas y pronósticas.Resultados: Se incluyeron 41 pacientes (58,5% varones, edad media 61 ±17 a˜nos). Treinta y unpacientes (75,6%) presentaban factores de riesgo vascular (FRV). Presentaron déficit motor (39,95,1%), dolor (20, 48,8%), déficit sensitivo (33, 80,4%) y alteración autonómica (24, 58,5%). Serealizó resonancia magnética (RM) en 37 pacientes (90,2%). En los 12 pacientes con secuenciasde difusión, esta estaba alterada en 10. La localización más afectada fue la dorsal (68,2%). Serealizó estudio vascular en 33 pacientes (80,4%). Las etiologías más frecuentes fueron disecciónaórtica en 6, ateroesclerosis demostrada en estudio vascular en 6, embolia fibrocartilaginosa en6, posquirúrgico en 5 e hipotensión en 4. El mecanismo etiológico quedó sin filiar en 12 pacientes(29,3%), 9 presentaban FRV. Al final del periodo de seguimiento (mediana 24 meses, rangointercuartílico 3-70), 12 pacientes (29,2%) presentaban deambulación autónoma. La presenciade FRV y la paraparesia se asociaron significativamente a peor pronóstico (p < 0,05).Discusión: El infarto medular es una patología con una etiología variada, que en muchos delos pacientes queda sin resolver. El pronóstico funcional a largo plazo es malo y depende de lascaracterísticas basales del paciente y de la forma de presentación clínica. La RM, especialmentelas secuencias de difusión, es útil en el diagnóstico precoz.(AU)


Introduction: Spinal cord infarction is a rare disease with a high rate of morbidity. Its diagnosiscan be challenging and controversy remains regarding the best treatment. Few case series havebeen published.Methods: We conducted a retrospective review of cases of spinal cord infarction attended ina tertiary hospital from 1999 to 2020. Aetiology and clinical, imaging, and prognostic featureswere assessed.Results: Forty-one patients (58.5% men, mean [standard deviation] age 61 [17] years) wereincluded in the study. Thirty-one patients (75.6%) presented vascular risk factors. Motor deficitswere recorded in 39 (95.1%), pain in 20 (48.8%), sensory deficits in 33 (80.4%), and autonomicdysfunction in 24 (58.5%). MRI was performed in 37 (90.2%) patients. Diffusion-weighted imageswere available for 12 patients, with 10 showing diffusion restriction. The thoracic region wasthe most frequently affected (68.2%). Vascular imaging studies were performed in 33 patients(80.4%). The most frequent aetiologies were aortic dissection (6 cases), atherosclerosis demons-trated by vascular imaging (6 cases), fibrocartilaginous embolism (6 cases), surgery (5 cases),and hypotension (4 cases). Aetiology was undetermined in 12 patients (29.3%), although 9 ofthese presented vascular risk factors. At the end of the follow-up period (median, 24 months;interquartile range, 3-70), 12 patients (29.2%) were able to walk without assistance. Vascularrisk factors and paraparesis were significantly associated with poorer prognosis (P < .05).Discussion: Spinal cord infarction may present diverse aetiologies, with the cause remainingundetermined in many patients. Long-term functional prognosis is poor, and depends on baselinecharacteristics and clinical presentation. MRI, and especially diffusion-weighted sequences, isuseful for early diagnosis.(AU)

ABSTRACT

Introducción: La eficacia de la trombectomía mecánica en territorio carotídeo en las primeras 24 horas se ha probado con trabajos publicados recientemente. Métodos: Revisión retrospectiva a partir de un registro prospectivo en nuestro centro de referencia de ictus para valorar la eficacia y seguridad del tratamiento endovascular realizado más allá de las 6 horas de evolución de los síntomas en pacientes con ictus isquémico agudo y oclusión de gran vaso en territorio carotídeo, entre noviembre de 2016 y abril de 2019. Resultados: Se recopilaron datos de 59 pacientes (55,9% mujeres, mediana de edad 71 años). Treinta y tres pacientes fueron detectados al despertar. El 57,6% de los casos fueron traslados secundarios. La mediana de NIHSS basal fue 16. La mediana del ASPECTS fue 8 y el 94,9% de los pacientes presentó > 50% de tejido salvable. El 88,1% de los pacientes logró una recanalización satisfactoria, en 5 pacientes después de 24 horas de evolución. El 67,8% de los casos logró la independencia funcional a los 90 días de seguimiento. Los pacientes que no lograron la independencia funcional presentaban mayor edad, mayor proporción de fibrilación auricular, mayor tiempo punción-recanalización y mayor puntuación NIHSS, tanto basal como al alta. Conclusión: En nuestra experiencia la trombectomía mecánica después de las 6 horas se asoció con buenos resultados de funcionalidad a los 90 días. La edad, la puntuación NIHSS, el tiempo punción-recanalización y la prevalencia de fibrilación auricular fueron factores determinantes en el pronóstico funcional. La eficacia de este tratamiento por encima de las 24 horas merece ser estudiada.(AU)


Introduction: Thrombectomy in the carotid artery territory was recently shown to be effective up to 24 hours after symptoms onset. Methods: We conducted a retrospective review of a prospective registry of patients treated at our stroke reference centre between November 2016 and April 2019 in order to assess the safety and effectiveness of mechanical thrombectomy performed beyond 6 hours after symptoms onset in patients with acute ischaemic stroke and large vessel occlusion in the carotid artery territory. Results: Data were gathered from 59 patients (55.9% women; median age, 71 years). In 33 cases, stroke was detected upon awakening; 57.6% of patients were transferred from another hospital. Median baseline NIHSS score was 16, and median ASPECTS score was 8, with 94.9% of patients presenting > 50% of salvageable tissue. Satisfactory recanalisation was achieved in 88.1% of patients, beyond 24 hours after onset in 5 cases. At 90 days of follow-up, 67.8% were functionally independent; those who were not were older and presented higher prevalence of atrial fibrillation, greater puncture-to-recanalisation time, and higher NIHSS scores, both at baseline and at discharge. Conclusion: In our experience, mechanical thrombectomy beyond 6 hours was associated with good 90-day functional outcomes. Age, NIHSS score, puncture-to-recanalisation time, and presence of atrial fibrillation affected functional prognosis. The efficacy of the treatment beyond 24 hours after onset merits study.(AU)

ABSTRACT

INTRODUCTION: Functional neurological disorders (FND) are a frequent reason for visits in neurology. However, specific training on these disorders during undergraduate and residency training is limited. This study assesses the knowledge, attitude and exposure of medical students to FNDs before completing their medical degree. PATIENTS AND METHODS: We conducted a 15-item survey to explore understanding, exposure and attitudes towards FNDs among sixth-year medical students at four Spanish universities. RESULTS: A total of 118 students (mean age 23.6 ± 1.2 years; 71.2% female) returned the survey. Of these, 88 (74.6%) were aware of the concept of FNDs and 78 (66.1%) had studied them in psychiatry classes. The term 'psychosomatic' was chosen by 54.1% of the students as the most appropriate term to refer to these disorders, and 111 (94.1%) believed that a history of sexual or physical abuse was common among FND patients. Fifty-seven students (48.3%) assumed that the diagnosis of FND was mostly a clinical diagnosis of exclusion and 63 (53.4%) indicated that it is managed only by psychiatry. One hundred and one students (85.6%) considered that adequate training on FNDs is an important aspect of their medical training. CONCLUSIONS: Medical students are aware of the existence of FNDs, but their preferred terminology, as well as the perceived aetiological factors, reflect that the historical view of these disorders is still deeply rooted. Medical students feel that they should receive adequate education on FNDs from specialists in neurology and psychiatry as part of their training.


TITLE: ¿Qué piensan los estudiantes de Medicina sobre los trastornos neurológicos funcionales?Introducción. Los trastornos neurológicos funcionales (TNF) son un motivo de consulta frecuente en neurología. Sin embargo, la formación específica sobre estos trastornos durante la formación universitaria y el período de residencia es limitada. En este estudio se evalúan los conocimientos, la actitud y la exposición de los estudiantes de Medicina a los TNF antes de terminar el grado de Medicina. Sujetos y métodos. Realizamos una encuesta de 15 ítems para explorar la comprensión, la exposición y las actitudes hacia los TNF entre los estudiantes de Medicina de sexto año en cuatro universidades españolas. Resultados. Devolvieron la encuesta 118 estudiantes (edad media 23,6 ± 1,2 años; 71,2%, mujeres). De ellos, 88 (74,6%) conocían el concepto de TNF y 78 (66,1%) los habían estudiado en las clases de psiquiatría. El 54,1% de los estudiantes eligió el término 'psicosomático' como el más adecuado para referirse a estos trastornos, y 111 (94,1%) creían que una historia de abuso sexual o físico era común entre los pacientes con TNF. Cincuenta y siete estudiantes (48,3%) asumieron que el diagnóstico de TNF era mayoritariamente un diagnóstico clínico de exclusión y 63 (53,4%) señalaron que el manejo se realiza únicamente desde psiquiatría. Ciento un estudiantes (85,6%) consideraron que una formación adecuada sobre los TNF es un aspecto importante de su formación médica. Conclusiones. Los estudiantes de Medicina son conscientes de la existencia de los TNF, pero la terminología preferida por ellos, así como los factores etiológicos percibidos, reflejan que la visión histórica acerca de estos trastornos está aún arraigada. Los estudiantes de Medicina consideran que deberían recibir una educación adecuada sobre los TNF como parte de su formación por parte de los especialistas en neurología y psiquiatría.

ABSTRACT

BACKGROUND AND PURPOSE: Specific respiratory tract infections, including COVID-19, may cause smell and/or taste disorders (STDs) with increased frequency. The aim was to determine whether new-onset STDs are more frequent amongst COVID-19 patients than influenza patients. METHOD: This was a case-control study including hospitalized patients of two tertiary care centres. Consecutive patients positive for COVID-19 polymerase chain reaction (cases) and patients positive for influenza polymerase chain reaction (historical control sample) were assessed during specific periods, employing a self-reported STD questionnaire. RESULTS: Seventy-nine cases and 40 controls were included. No significant differences were found in basal features between the two groups. New-onset STDs were significantly more frequent amongst cases (31, 39.2%) than in the control group (5, 12.5 %) [adjusted odds ratio 21.4 (2.77-165.4, P = 0.003)]. COVID-19 patients with new-onset STDs were significantly younger than COVID-19 patients without STDs (52.6 ± 17.2 vs. 67.4 ± 15.1, P < 0.001). Amongst COVID-19 patients who presented STDs, 22 (70.9%) recalled an acute onset and it was an initial manifestation in 11 (35.5%). Twenty-five (80.6%) presented smell disorders (mostly anosmia, 14, 45.2%) and 28 (90.3%) taste disorders (mostly ageusia, 14, 45.2%). Only four (12.9 %) reported concomitant nasal obstruction. The mean duration of STD was 7.5 ± 3.2 days and 12 patients (40%) manifested complete recovery after 7.4 ± 2.3 days of onset. CONCLUSION: New-onset STDs were significantly more frequent amongst COVID-19 patients than influenza patients; they usually had an acute onset and were commonly an initial manifestation. The use of STD assessment in anamnesis as a hint for COVID-19 and to support individuals' self-isolation in the current epidemic context is suggested.
