Computerized assessment of handwriting in de novo Parkinson's disease: A kinematic study.

INTRODUCTION: Dysgraphia, a recognized PD motor symptom, lacks effective clinical assessment. Current evaluation relies on motor assessment scales. Computational methods introduced over the past decade offer an objective dysgraphia assessment, considering size, duration, speed, and handwriting fluency. Objective evaluation of dysgraphia may be of help for early diagnosis of PD. OBJECTIVE: Computerized assessment of dysgraphia in de novo PD patients and its correlation with clinical scales. METHODS: We evaluated 38 recently diagnosed, premedication PD patients and age-matched controls without neurological disorders. Participants wrote "La casa de Pamplona es bonita" three times on paper and once on a Wacom tablet under the paper, totaling four phrases. Writing segments of 5-10 s were analyzed. The Wacom tablet captured kinematic data, including mean velocity, mean acceleration, and pen pressure. Data were saved in.svc format and analyzed using specialized software developed by Tecnocampus Mataró. Standard clinical practice data, Hoehn & Yahr staging, and UPDRS scales were used for evaluation. RESULTS: Significant kinematic differences existed; patients had lower mean speed (27 ± 12 vs. 48 ± 18, p < 0.0001) and mean acceleration (7.2 ± 3.9 vs. 15.01 ± 7, p < 0.0001) than controls. Mean speed and mean acceleration correlated significantly with UPDRS III scores (speed: r = -0.52, p < 0.0007; acceleration: r = 0.60, p < 0.0001), indicating kinematic parameters' potential in PD evaluation. CONCLUSIONS: Dysgraphia is identifiable in PD patients, even de novo, indicating an early symptom and correlates with clinical scales, offering potential for objective PD patient evaluation.

Safinamide in Clinical Practice: A Spanish Multicenter Cohort Study.

Background: Safinamide is an approved drug for the treatment of motor fluctuations of Parkinson's Disease (PD) patients with a potential benefit on non-motor symptoms (NMS). Methods: A retrospective multicenter cohort study was conducted, in which the clinical effect of safinamide on both motor and NMS was assessed by the Clinical Global Impression of Change scale. Furthermore, we assessed the appearance of adverse events (AEs) and its effect on dyskinesia, that were also recorded in non-fluctuating PD patients and in those previously treated with rasagiline. Results: We included 213 PD patients who received safinamide in addition to their regular levodopa therapy. Thirty-five withdrew prematurely from safinamide, mainly because of AEs. Out of 178, clinical improvement on motor and NMS was found in 76.4% and 26.2%, respectively. A total of 44 reported AEs of mild intensity. We did not find a difference concerning the clinical benefit or AEs when comparing either patients who had or had not been taking Monoamine Oxidase B Inhibitor (MAOB-I) previously or between patients with and without motor complications. Conclusions: Safinamide is an effective and safe add-on to levodopa drug for PD patients. Moreover, safinamide could elicit an additional clinical improvement in PD patients previously treated with other MAOB-I and in non- fluctuating patients with suboptimal motor control.

Efficacy of long-term continuous subcutaneous apomorphine infusion in advanced Parkinson's disease with motor fluctuations: a multicenter study.

Continuous subcutaneous apomorphine infusion (CSAI) is, at present, an alternative option for advanced Parkinson's disease (PD) with motor fluctuations. We studied the evolution of patients with PD and severe motor fluctuations long-term treated with CSAI. We reviewed data from 82 patients with PD (mean age, 67 +/- 11.07; disease duration, 14.39 +/- 5.7 years) and severe motor fluctuations referred to 35 tertiary hospitals in Spain. These patients were long-term treated (for at least 3 months) with CSAI and tolerated the procedure without serious side effects. We compared the baseline data of these 82 patients (before CSAI) with those obtained from the last follow-up visit of each patient. The mean follow-up of CSAI was 19.93 +/- 16.3 months. Mean daily dose of CSAI was 72.00 +/- 21.38 mg run over 14.05 +/- 1.81 hours. We found a statistically significant reduction in off-hours, according to self-scoring diaries (6.64 +/- 3.09 vs. 1.36 +/- 1.42 hours/day, P < 0.0001), total and motor UPDRS scores (P < 0.0001), dyskinesia severity (P < 0.0006), and equivalent dose of antiparkinsonian therapy (1,405 +/- 536.7 vs. 800.1 +/- 472.9 mg of levodopa equivalent units P < 0.0001). CSAI is an effective option for patients with PD and severe fluctuations, poorly controlled by conventional oral drug treatment.

Mitos y evidencias en el empleo de la toxina botulínica: espasticidad del adulto y del niño con parálisis cerebral / Myths and evidence on the use of botulinum toxin: spasticity in adults and in children with cerebral palsy

Introducción. La espasticidad es un problema médico frecuente que impacta de forma significativa en la calidad de vida de los pacientes y sus familias. Objetivo. Analizar y dar respuesta a diferentes cuestiones en el uso de la toxina botulínica tipo A (TBA) en nuestra práctica clínica habitual. Desarrollo. Un grupo de expertos en neurología elaboró una lista de temas relacionados con el uso de la TBA. Se consideraron dos grandes bloques: espasticidad del adulto y del niño con parálisis cerebral. Se realizó una revisión de la bibliografía que incluyó los diferentes artículos publicados en español, inglés y francés hasta junio de 2016. El documento se estructuró como un cuestionario que incluyó las preguntas que, según el criterio del panel, podrían generar mayor controversia o duda. El borrador inicial del documento fue revisado por los miembros del panel y se realizaron las modificaciones necesarias hasta alcanzar el mayor grado de consenso. A continuación, el texto final fue validado. Se incluyeron diferentes preguntas sobre diferentes aspectos de la espasticidad en adultos: evaluación de la espasticidad, técnicas de infiltración, dosis, número de puntos, etc. En cuanto a la espasticidad en los niños con parálisis cerebral, se analizaron preguntas como: edad mínima de infiltración, métodos de sedoanalgesia, etc. Conclusiones. Esta revisión constituye una herramienta para neurólogos, médicos rehabilitadores y residentes de ambas especialidades, dentro de diferentes ámbitos específicos del manejo de la TBA (AU)

Introduction. Spasticity is a medical problem with a high incidence that significantly impact on the quality of life of patients and their families. Aim. To analyze and to answer different questions about the use of botulinum toxin type A (BTA) in our clinical practice. Development: A group of experts in neurology develop a list of topics related with the use of BTA. Two big groups were considered: spasticity in adults and in children with cerebral palsy. A literature search at PubMed for English, French, and Spanish language articles published up to June 2016 was performed. The manuscript was structured as a questionnaire that includes those questions that, according to the panel opinion, could generate more controversy or doubt. The initial draft was reviewed by the expert panel members to allow for modifications, and after subsequent revisions for achieving the highest degree of consensus, the final text was then validated. Different questions about diverse aspects of spasticity in adults, such as methods for evaluating spasticity, infiltration techniques, doses, number of infiltration points, etc. Regarding spasticity in children with cerebral palsy, the document included questions about minimum age of infiltration, methods of analgesia, etc. Conclusions: This review is a tool for continuous training for neurologist and rehabilitation specialist and residents of both specialties, about different specific areas of the management of BTA (AU)
