Perception of task duration affects metabolic cost during split-belt adaptation.

Humans continuously adapt locomotor patterns. Whether metabolic cost reduction is the primary objective or a by-product of the observed biomechanical changes during adaptation is not known. The main goal of our study is to determine if perception of task duration affects the adaptation of locomotor patterns to reduce energetic cost during split-belt walking. We tested the hypothesis that individuals who believe they will sustain a locomotor adaptation task for a prolonged time will reduce metabolic cost by adapting toward a walking pattern associated with lower mechanical work. N=14 participants walked on a split-belt treadmill for 10 minutes with knowledge of task duration (group K), while N=15 participants performed the task under the assumption that they would walk for 30 minutes (group U). Both groups walked for 10 minutes with the belts moving at 1.5 and 0.5 m/s, followed by 6 minutes of walking with both belts at 1.0 m/s. We observed a significant main effect of Time (p<0.001, observed power 1.0) and the interaction of Time×Group (p=0.004, observed power 0.84) on metabolic cost. Participants in the U group had a metabolic cost that was 12% lower during adaptation compared to the K group, which did not reduce metabolic cost during adaptation. The metabolic cost reduction observed in group U was not associated with biomechanical changes during adaptation. Our results indicate that metabolic cost reduction has a primary role in tasks that need to be sustained for a prolonged time, and this reduction is not only related to biomechanical factors.

Variants rs2758346, rs5746094, and rs2758331 of SOD2 gene: association study with breast cancer in a Mexican population and their analysis in silico.

OBJECTIVE: The aim of the study was to analyze the association between the superoxide dismutase 2 (SOD2) gene variants rs2758346, rs5746094, and rs2758331 and breast cancer (BC) in the Mexican population as well as to perform in silico assessments of the variants' potential impact. PATIENTS AND METHODS: We performed in silico analysis and analyzed 489 healthy women and 467 BC patients using TaqMan assays and Real-Time PCR. RESULTS: The TT genotype, the T allele of the rs2758346 variant, and the CC genotype of both rs5746094 and rs2758331 were identified as BC risk factors (p < 0.05). The TT and CTTT genotype of the rs2758346 variant stratified by the presence of ki-67 (> 20%), TCCC, and estrogen receptor (ER)-positive of the rs5746094 variant, and the CC and CT genotypes of rs2758331 stratified by menopause status and non-chemotherapy response were risk factors. The TTC and TTA haplotypes are risk factors for BC. In silico analysis revealed that the rs2758346, rs5746094, and rs2758331 variants could influence SOD2 gene regulation by transcription factors and circulating RNAs (circRNAs). CONCLUSIONS: The rs2758346, rs5746094, and rs2758331 variants of the SOD2 gene were associated with BC risk and could influence SOD2 regulation by transcription factors and circRNAs.

Low rCBV values in glioblastoma tumor progression under chemoradiotherapy.

PURPOSE: After standard treatment for glioblastoma, perfusion MRI remains challenging for differentiating tumor progression from post-treatment changes. Our objectives were (1) to correlate rCBV values at diagnosis and at first tumor progression and (2) to analyze the relationship of rCBV values at tumor recurrence with enhancing volume, localization of tumor progression, and time elapsed since the end of radiotherapy in tumor recurrence. METHODS: Inclusion criteria were (1) age > 18 years, (2) histologically confirmed glioblastoma treated with STUPP regimen, and (3) tumor progression according to RANO criteria > 12 weeks after radiotherapy. Co-registration of segmented enhancing tumor VOIs with dynamic susceptibility contrast perfusion MRI was performed using Olea Sphere software. For tumor recurrence, we correlated rCBV values with enhancing tumor volume, with recurrence localization, and with time elapsed from the end of radiotherapy to progression. Analyses were performed with SPSS software. RESULTS: Sixty-four patients with glioblastoma were included in the study. Changes in rCBV values between diagnosis and first tumor progression were significant (p < 0.001), with a mean and median decreases of 32% and 46%, respectively. Mean rCBV values were also different (p < 0.01) when tumors progressed distally (radiation field rCBV values of 1.679 versus 3.409 distally). However, changes and, therefore, low rCBV values after radiotherapy in tumor recurrence were independent of time. CONCLUSION: Chemoradiation alters tumor perfusion and rCBV values may be decreased in the setting of tumor progression. Changes in rCBV values with respect to diagnosis, with low rCBV in tumor progression, are independent of time but related to the site of recurrence.

Clinical utility of a personalized and long-term monitoring device for Parkinson's disease in a real clinical practice setting: An expert opinion survey on STAT-ON™.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

[Opicapone for the treatment of Parkinson's disease: real-life data in Spain]. / Opicapona para el tratamiento de la enfermedad de Parkinson: datos de vida real en España.

Opicapone is a catechol-O-methyl-transferase (iCOMT) inhibitor authorized in Europe in 2016 and indicated as adjunctive therapy to preparations of levodopa/ DOPA decarboxylase inhibitors in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilised on those combinations. The efficacy of opicapone in these patients has been demonstrated in two pivotal randomized clinical trials, BIPARK I and BIPARK II, in which it has demonstrated its superiority versus placebo and non-inferiority versus entacapone. Although they constitute the gold standard for the evaluation of interventions, randomized clinical trials present limitations of external validity due to the use of strict eligibility criteria. Therefore, it is considered necessary to have a more comprehensive evaluation of the efficacy of the drug, complementing the information obtained from randomized clinical trials with that of "real world or real clinical practice" studies. The objective of this review has been to collect and put into perspective the information available on opicapone coming from real clinical practice studies in Spain. The data from Spain with opicapone in 18 series with more than 1,000 patients in total, confirm the safety and efficacy previously reported with this iCOMT. Furthermore, they show that opicapone is especially useful in patients with a less advanced stage of the disease and mild motor fluctuations, which would suggest that the earlier its introduction in the therapeutic scheme for the management of motor fluctuations, the better is the benefit-risk ratio for the drug.

TITLE: Opicapona para el tratamiento de la enfermedad de Parkinson: datos de vida real en España.Resumen. La opicapona es un inhibidor de la catecol-O-metiltransferasa (iCOMT) autorizado en Europa en 2016 como terapia adyuvante a las preparaciones de levodopa/inhibidores de la dopa descarboxilasa en pacientes adultos con enfermedad de Parkinson y fluctuaciones motoras de final de dosis que no puedan ser estabilizados con esas combinaciones. La eficacia de la opicapona en estos pacientes ha sido demostrada en dos ensayos clínicos pivotales, BIPARK I y BIPARK II, en los que se ha demostrado la superioridad frente al placebo y la no inferioridad frente a la entacapona. A pesar de que constituyen el estándar para la evaluación de intervenciones, los ensayos clínicos aleatorizados presentan limitaciones de validez externa debidas a la utilización de criterios estrictos de elegibilidad. Por tanto, se considera necesario disponer de una evaluación más amplia de la eficacia general del fármaco, complementando la información de los ensayos clínicos aleatorizados con estudios de 'vida real o práctica clínica real'. El objetivo de esta revisión ha sido recopilar y poner en perspectiva la información disponible sobre los resultados de la opicapona en estudios de práctica clínica real en España. Los datos acumulados en España con opicapona en 18 series con más de 1.000 pacientes confirman la seguridad y la eficacia de este iCOMT comunicadas previamente. Además, muestran que la opicapona es especialmente útil en pacientes en un estadio de la enfermedad menos avanzado y fluctuaciones motores leves, lo que sugeriría una mejor relación beneficio-riesgo cuanto más temprana sea su introducción en el esquema terapéutico para el tratamiento de las fluctuaciones motoras.

Brain activity in well-controlled perinatally HIV-infected young adults: a fMRI pilot study. / Actividad cerebral en jóvenes infectados por el virus de la inmunodeficiencia humana por transmisión vertical: estudio piloto de resonancia magnética funcional.

INTRODUCTION AND AIM: Perinatal transmission of human immunodeficiency virus (PHIV) is considered a chronic disease that has highlighted several cognitive deficits. From birth to early adulthood, cognition is known to play a fundamental role. However, although neurocognitive processes associated with PHIV have been extensively described by psychometric testing, data is scarce on neural activity from functional magnetic resonance imaging (fMRI) which provides in vivo physiological information. SUBJECTS AND METHODS: We studied described impaired cognitive processes using fMRI on a group of PHIV adolescents with good immunovirological indications and healthy matched controls. Psychological status and neurocognitive functions were also assessed. RESULTS: There were no significant differences between HIV+ and HIV- groups, either on neurocognitive testing nor in fMRI activity for phonological fluency tasks. Prolonged duration of cART was positively associated with greater brain activity in left inferior frontal gyrus (LIFG) which could indicate functional compensation. CONCLUSIONS: These results suggest that neural activity through fMRI in PHIV adolescents with good daily functioning and good immunovirological control may be similar to their peers.

TITLE: Actividad cerebral en jóvenes infectados por el virus de la inmunodeficiencia humana por transmisión vertical: estudio piloto de resonancia magnética funcional.Introducción y objetivos. La infección por el virus de la inmunodeficiencia humana de transmisión vertical (VIH-TV) constituye una enfermedad crónica que puede asociar múltiples alteraciones cognitivas que pueden influenciar el desarrollo de estos pacientes desde la infancia a la vida adulta. Sin embargo, aunque las alteraciones neurocognitivas vinculadas al VIH-TV están ampliamente descritas y valoradas mediante pruebas psicométricas, no existen apenas estudios de actividad neuronal medida a través de la resonancia magnética funcional (RMf). Sujetos y métodos. Analizar la utilidad de la RMf a través de la realización de tareas motoras y de fluidez verbal en un grupo de adolescentes y jóvenes con VIH-TV con buen control inmunovirológico y compararlo con un grupo control negativo de características similares. Se evaluaron también alteraciones psicológicas y funciones neurocognitivas. Resultados. No se encontraron diferencias significativas entre el grupo VIH+ y el grupo control para las tareas ejecutadas durante la RMf ni en la evaluación neurocognitiva. Un mayor tiempo de terapia combinada antirretroviral se asoció de forma directa con una mayor actividad en el giro frontal inferior izquierdo, lo cual podría indicar una posible compensación funcional. Conclusiones. Estos resultados sugieren que la actividad neuronal medida a través de la RMf en adolescentes con VIH-TV y buen control inmunovirológico es similar a la de sus pares.

Cambios en la tolerancia al ejercicio, disnea y calidad de vida a las 8 vs. 12 semanas de rehabilitación pulmonar en pacientes con EPOC / Changes in tolerance to exercise, dyspnoea and quality of life at 8 vs. 12 weeks of pulmonary rehabilitation in patients with COPD

Introducción En pacientes con enfermedad pulmonar obstructiva crónica (EPOC), la rehabilitación pulmonar reporta mejorías en la tolerancia al ejercicio, la calidad de vida y la disminución de síntomas; sin embargo, pocos estudios comparan programas de rehabilitación pulmonar de menor y mayor duración. El objetivo fue describir los beneficios de la RP en cuanto a tolerancia al ejercicio, percepción de disnea y de calidad de vida, en pacientes con EPOC que asisten a un programa de rehabilitación pulmonar durante 8 semanas comparados con los que asisten durante 12 semanas en una institución de tercer nivel de la ciudad de Cali-Colombia. Métodos Estudio cuasiexperimental vinculando pacientes con EPOC, 15 pacientes en el programa de rehabilitación pulmonar de 8 semanas y 15 pacientes en el programa de rehabilitación pulmonar de 12 semanas. Se valoró al inicio y final del programa el índice de masa corporal, distancia recorrida en el test de caminata de los 6 minutos (TC6M), la calidad de vida CRQ-SAS. Resultados El índice de masa corporal no presentó cambios estadísticamente significativos en los grupos, la tolerancia al ejercicio presentó mejoría estadísticamente significativa en la rehabilitación pulmonar de 12 semanas (p<0,05), el cuestionario CRQ-SAS evidenció una mejoría en todos los dominios, pero no hubo diferencias entre ambos grupos. Conclusiones Pacientes con EPOC presentaron mejorías estadísticamente significativas después del programa de rehabilitación pulmonar en variables como la disnea y la calidad de vida; sin embargo, solo el grupo de rehabilitación pulmonar de 12 semanas presentó mejorías estadísticamente significativas en la distancia recorrida del TC6M comparado con el grupo de rehabilitación pulmonar de 8 semanas (AU)

Introduction In patients with chronic obstructive pulmonary disease (COPD), pulmonary rehabilitation reports improvements in exercise tolerance, quality of life and decrease in symptoms; however, few studies compare shorter and longer pulmonary rehabilitation programmes. The objective was to describe the benefits of PR in terms of exercise tolerance, perception of dyspnoea and quality of life, in patients with COPD attending a pulmonary rehabilitation programme for 8 weeks compared to those attending for 12 weeks in a third level institution in the city of Cali, Colombia. Methods Quasi-experimental study linking patients with COPD, 15 patients in the 8-week pulmonary rehabilitation programme and 15 patients in the 12-week pulmonary rehabilitation programme. Body mass index (BMI), distance covered in the 6-minute walk test (TC6M), quality of life CRQ-SAS questionnaire were assessed at the beginning and end of the programme. Results BMI did not show statistically significant changes in the groups, exercise tolerance showed statistically significant improvement in 12-week pulmonary rehabilitation programme (p<.05), the CRQ-SAS questionnaire evidences improvement in all domains, but there were no differences between both groups. Conclusions COPD patients, statistically significant improvement after the pulmonary rehabilitation programme in variables such as dyspnoea and quality of life; however, only the 12-week pulmonary rehabilitation programme group presented statistically significant improvements in the distance travelled of the TC6M compared to the 8-week pulmonary rehabilitation programme group (AU)

Clinical utility of a personalized and long-term monitoring device for Parkinson's disease in a real clinical practice setting: An expert opinion survey on STAT-ON™.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

Factors associated with visits to general practitioners in patients with schizophrenia in Malaga.

BACKGROUND: Patients with psychiatric disorders have more physical problems than other patients, so their follow-up by the general practitioner is particularly important for them. METHODS: We aimed to elaborate a multilevel explanatory model of general practitioner (GP) visits made by patients with schizophrenia and related disorders (SRD). An observational, cross-sectional study was conducted from January 1, 2008 to July 1, 2011, in the area of the Clinical Management Unit of Mental Health (CMU-MH) of the Regional Hospital of Malaga (Spain). The eligible population consisted of all patients with SRD in contact with a GP residing in the study area. Our dependent variable was total number GP visits. The independent variables were: 1) patient variables (sociodemographic and clinical variables); 2) primary care centre (PCC) variables. We performed descriptive analysis, bivariate analysis and multilevel regression. RESULTS: Four hundred ninety four patients were included. Mean annual number of GP visits was 4.1. Female sex, living in a socioeconomically deprived area, a diagnosis of schizoaffective disorder and contact with a GP who had a more active approach to mental health issues were associated with a higher number of visits whilst being single and good communication between the PCC and mental health teams were associated with a lower number of GP visits. CONCLUSIONS: Number of GP visits was not just associated with patient factors, but also with organisational and the involvement of health professionals, for example GPs with an active approach to mental health issues.

[Risk factors associated with the development of enterocolitis in Hirschsprung's disease]. / Factores de riesgo asociados al desarrollo de enterocolitis en la enfermedad de Hirschsprung.

OBJECTIVES: Hirschsprung's-associated enterocolitis (HAEC) is a live-threatening complication that remains badly understood. Our objective is to identify the risk factors related to the development of HAEC in the cohort of patients with Hirschsprung's disease (HD) treated in our center. METHODS: We reviewed the patients treated for HD between 2000 and 2016. Ninety four patients were included, and the clinical details related to the disease were evaluated. Our primary outcome measure was the development of HAEC. Relative risks are presented with 95% confidence intervals. RESULTS: Twenty seven patients out of the ninety four (28.7%) suffered HAEC. None of them died from this complication. The extended aganglionosis, the need of a preoperative stoma, a transabdominal surgery and the diagnosis before the age of 7.2 months were related to a higher risk of suffering HAEC. CONCLUSIONS: HAEC remains a common complication in patients suffering from HD, especially those with complex forms. The identification of the risk factors could result in a better control of the HAEC, which lead to a faster diagnosis and treatment, reducing the morbi-mortality related to HAEC.

OBJETIVO: La enterocolitis (EC) asociada a la enfermedad de Hirschsprung (EdH) es una entidad de etiopatogenia desconocida y potencialmente mortal. Nuestro objetivo es identificar los factores implicados en el desarrollo de EC en una cohorte de pacientes con EdH tratados en el nuestro centro. METODOS: Se revisaron los pacientes tratados por EdH en el periodo 2000-2016. Se incluyeron 94 pacientes, recogiendo de las historias clínicas variables demográficas y todas las relacionadas con la enfermedad. Se realizó un estudio de riesgo uni y multivariado usando como variable dependiente la existencia de un cuadro de enterocolitis. Los resultados se presentan con riesgo relativo (RR) con su intervalo de confianza al 95%. RESULTADOS: De los 94 pacientes estudiados, 27 (28,7%) sufrieron algún episodio de EC. Ninguno falleció por esta causa. La afectación intestinal extensa, la necesidad de una ostomía de descarga en el proceso diagnóstico, la cirugía abierta y el diagnóstico anterior a los 7,2 meses de vida se asociaron en el análisis univariante a un mayor riesgo de desarrollar EC. En el multivariante, tan solo el diagnostico precoz y la cirugía abierta quedaron como variables asociadas al riesgo de EC. CONCLUSIONES: La EC sigue siendo una complicación habitual en la EdH, especialmente en las formas más largas y complejas. La identificación de los factores que la favorecen permitiría un mayor control, una mejor prevención secundaria ante el comienzo de los síntomas y un tratamiento más precoz, lo que lograría disminuir su morbilidad.

En el multivariante, tan solo el diagnostico precoz y la cirugía abierta quedaron como variables asociadas al riesgo de EC. Conclusiones. La EC sigue siendo una complicación habitual en la EdH, especialmente en las formas más largas y complejas. La identificación de los factores que la favorecen permitiría un mayor control, una mejor prevención secundaria ante el comienzo de los síntomas y un tratamiento más precoz, lo que lograría disminuir su morbilidad (AU)

Objectives. Hirschsprung's-associated enterocolitis (HAEC) is a live-threatening complication that remains badly understood. Our objective is to identify the risk factors related to the development of HAEC in the cohort of patients with Hirschsprung's disease (HD) treated in our center. Methods. We reviewed the patients treated for HD between 2000 and 2016. Ninety four patients were included, and the clinical details related to the disease were evaluated. Our primary outcome measure was the development of HAEC. Relative risks are presented with 95% confidence intervals. Results. Twenty seven patients out of the ninety four (28.7%) suffered HAEC. None of them died from this complication. The extended aganglionosis, the need of a preoperative stoma, a transabdominal surgery and the diagnosis before the age of 7.2 months were related to a higher risk of suffering HAEC. Conclusions. HAEC remains a common complication in patients suffering from HD, especially those with complex forms. The identification of the risk factors could result in a better control of the HAEC, which lead to a faster diagnosis and treatment, reducing the morbimortality related to HAEC (AU)

Multiple-resistance to ivermectin and benzimidazole of a Haemonchus contortus population in a sheep flock from mainland France, first report.

Anthelmintic resistance was explored by fecal egg count reduction test in a sheep flock from the French Pyrenees at the request of the veterinary practitioner after a poor response to anthelmintics was noted. The FECRT confirmed the suspicion with a mean percentage of reduction in egg excretions of 45% (CI 95%: - 40 to 78.5) and 0% (CI95%: - 162 to 49) within the ivermectin and the benzimidazole groups respectively. Haemonchus contortus was shown to be the IVM and BZ resistant species after morphological and molecular characterizations whereas Teladorsagia circumcincta was probably resistant to BZ only. The H. contortus population was still susceptible to moxidectin, closantel and levamisole. As this sheep flock is a transhumant flock, the spread of this multiple-resistant Haemonchus contortus population to the other sheep flocks sharing the same pastures in Pyrenean Mountains is highly likely. From the knowledge of the authors, this is the first report of multi-resistance to ivermectin and benzimidazole of a Haemonchus contortus population in mainland France.

[Language disorders in acute cerebellitis: beyond dysarthria]. / Alteraciones del lenguaje en la cerebelitis aguda: mas alla de la disartria.

INTRODUCTION: Acute cerebellitis is one of the main causes of cerebellar syndrome in infancy. Among the wide range of manifestations, headache and ataxia being the most predominant, we can find other less frequent, although nonetheless interesting, ones, such as language disorders, which go beyond the well-known cerebellar dysarthria. The different combinations in which the symptoms can appear, especially when not accompanied by ataxia, make the condition a real challenge for the clinician. CASE REPORTS: Two patients, aged 2 and 4 years, with clinical features, lab tests and neuroimaging results consistent with parainfectious acute cerebellitis. Both of them also presented a striking language disorder, one in the form of cerebellar mutism and the other in the form of hypofluency and agrammatism, the latter also developing in the absence of ataxia. Both cases progressed favourably, and mild speech alterations persisted in the follow-up visits. CONCLUSIONS: Cases such as these expand the range of clinical manifestations of acute cerebellitis. The involvement of the cerebellum in neurocognitive processes like language is becoming increasingly more important and, although many aspects are still only speculations, managing to define its true role will have important repercussions on the diagnosis, treatment and long-term prognosis of these patients.

TITLE: Alteraciones del lenguaje en la cerebelitis aguda: mas alla de la disartria.Introduccion. La cerebelitis aguda es una de las principales causas de sindrome cerebeloso en la infancia. Entre un amplio elenco de manifestaciones, en el que predominan la cefalea y la ataxia, podemos encontrar otras menos habituales, aunque interesantes, como las alteraciones del lenguaje, mas alla de la bien conocida disartria cerebelosa. Las diferentes combinaciones en que pueden aparecer los sintomas, especialmente cuando no se acompañan de ataxia, hacen de este cuadro un verdadero reto para el clinico. Casos clinicos. Se presentan dos pacientes, de 2 y 4 años, con clinica, pruebas de laboratorio y neuroimagen compatibles con cerebelitis aguda parainfecciosa, que asociaron una llamativa alteracion del lenguaje, uno en forma de mutismo cerebeloso y otro en forma de hipofluencia y agramatismo, y este ultimo cursaba ademas en ausencia de ataxia. La evolucion de ambos casos fue buena, y persistieron leves alteraciones del habla en el seguimiento posterior. Conclusiones. Casos como estos amplian el espectro de manifestaciones clinicas de la cerebelitis aguda. Cada vez cobra mayor importancia la participacion del cerebelo en procesos neurocognitivos como el lenguaje y, aunque muchos aspectos son aun especulativos, alcanzar a definir su verdadero papel tendra una repercusion en el diagnostico, el tratamiento y el pronostico a largo plazo de estos pacientes.

[Antibiotics and gait disorders]. / Antibioticos y trastornos de la marcha.

The neurological toxicity of many antibiotics has been reported in a number of articles and clinical notes. In this review antibiotics are classified according to the physiopathogenic mechanism that can give rise to a gait disorder, taking both clinical and experimental data into account. An exhaustive search was conducted in Google Scholar and PubMed with the aim of finding reviews, articles and clinical cases dealing with gait disorders secondary to different antibiotics. The different antibiotics were separated according to the physiopathogenic mechanism that could cause them to trigger a gait disorder. They were classified into antibiotics capable of producing cerebellar ataxia, vestibular ataxia, sensitive ataxia or an extrapyramidal gait disorder. The main aim was to group all the drugs that can give rise to a gait disorder, in order to facilitate the clinical suspicion and, consequently, the management of patients.

TITLE: Antibioticos y trastornos de la marcha.La toxicidad neurologica de muchos antibioticos se ha documentado en numerosos articulos y notas clinicas. En esta revision se clasifican los antibioticos en funcion del mecanismo fisiopatogenico por el que pueden provocar un trastorno de la marcha, teniendo en cuenta tanto datos clinicos como experimentales. Se ha realizado una busqueda exhaustiva en Google Scholar y PubMed con el objetivo de encontrar revisiones, articulos y casos clinicos acerca de trastornos de la marcha secundarios a distintos antibioticos. Se han separado los diferentes antibioticos en funcion del mecanismo fisiopatogenico por el cual podrian producir una alteracion de la marcha. Se han clasificado en antibioticos capaces de producir ataxia cerebelosa, ataxia vestibular, ataxia sensitiva o un trastorno de la marcha extrapiramidal. El principal objetivo era agrupar todos los farmacos que pueden provocar un trastorno de la marcha, para facilitar la sospecha clinica y, en consecuencia, el tratamiento de los pacientes.
