Continuous Subcutaneous Apomorphine Infusion before Subthalamic Deep Brain Stimulation: A Prospective, Comparative Study in 20 Patients.

BACKGROUND: Studies comparing the clinical efficacy of apomorphine infusion (APO) with subsequent subthalamic deep brain stimulation (STN-DBS) in advanced Parkinson's disease (aPD) are currently lacking. Retrospective data have shown that patients treated with APO are usually older, have a more prolonged disease, and a more severe phenotype. OBJECTIVE: To compare the benefit of APO with that of STN-DBS on motor, non-motor, cognitive, and quality of life in the same patient when given sequentially. METHODS: We prospectively analyzed 20 aPD patients over 3 different treatment phases: baseline (optimized medical treatment), during APO treatment, and during subsequent STN-DBS treatment. The APO and STN-DBS phases were stable for 6 months, and evaluation of the different treatments was separated by 6 months. RESULTS: Compared to baseline, APO, and STN-DBS reduced mean daily off time by 70.5% and 89.3% (P = 0.012), respectively, and scores for Unified Parkinson's Disease Rating Scale (UPDRS) IV by 27.5% and 80.5% (P ≤ 0.001), Non-motor symptoms scale (NMSS) by 24.6% and 49.3% (P ≤ 0.001), Montgomery Asberg depression scale (MADRS) by 7.4% and 39.0% (P = 0.27), Starkstein apathy scale (SAS) by 51.1% and 39.9% (P = 0.734), Parkinson's disease sleep scale 2 (PDSS-2) by 25.7% and 56.7% (P ≤ 0.001), and Parkinson's disease questionnaire 39 item (PDQ-39) by 39.6% and 64.9% (P ≤ 0.001). Global cognition did not change with either therapy, but phonetic fluency worsened after STN-DBS compared to APO (P = 0.022). CONCLUSIONS: Both APO and STN-DBS improved motor and non-motor symptoms and quality of life compared to optimized medical treatment in aPD. Overall, STN-DBS was the most effective treatment, but APO showed a pronounced benefit on motor symptoms. Effective treatment for aPD should not be delayed, even when waiting for surgery.

Objetivos: Analizar la supervivencia de una cohorte de pacientes con metástasis cerebrales tratados con radiocirugía y determinar qué factores pueden influir en los resultados. Pacientes y método: Estudio retrospectivo descriptivo sobre una cohorte de 126 pacientes diagnosticados de metástasis intracraneal tratados con radiocirugía. Se excluyeron aquellos casos en los que se realizó cirugía (antes o después de la radiocirugía). Se analizó la supervivencia en función de factores clínicos (edad, sexo, tumor primario), radiológicos (número, localización y volumen de las lesiones) y de radioterapia (dosis de tratamiento, radioterapia holocraneal). Se realizó análisis univariante y multivariante de regresión de Cox. Resultados: Entre febrero de 2008 y abril de 2015 se trataron 225 metástasis cerebrales en 126 pacientes con edad media de 59,8 ± 11,6 años. La mediana de supervivencia fue de 8,2 meses. La supervivencia global a los 6, 12 y 24 meses fue del 60,3, del 31,5 y del 12,8%, respectivamente. Los orígenes más frecuentes fueron pulmonar (59,5%) y mama (14,3%), y la localización principal, los hemisferios cerebrales (77%). El volumen medio fue de 10,35cc (0,2-43,5). Se encontraron como factores significativos de supervivencia, entre otros: edad menor de 60años (p = 0,046), sexo femenino (p < 0,001), cáncer de mama (p < 0,001); KPS > 80 (p = 0,001), puntuación en la escala SIR > 6,5 (p = 0,031), escala GPA ≥ 2,5 (p = 0,003). Conclusiones: La radiocirugía es una técnica adecuada para el tratamiento de las metástasis cerebrales, y entre los factores pronósticos encontrados destacan la edad menor de 60 años, el sexo femenino y las mejores puntuaciones en las escalas de Karfnosky, SIR y GPA

Objective: To analyse the survival rate of a cohort of patients with intracranial metastases treated with radiosurgery, and to determine the factors that influence the results. Patients and method: Retrospective analysis performed on a cohort of 126 patients undergoing radiosurgery for brain metastases. Patients treated with surgery before or after radiosurgery were excluded. Survival is analysed based on clinical (age, sex, primary tumour), radiological (number, location and volume of lesions), and radiotherapy factors (treatment dose, holocraneal radiation). Univariate and multivariate analyses were performed to determine significant prognostic factors. Results: A total of 225 brain metastases in 126 patients, with a mean age of 59.8 ± 11.6 years, were treated between February 2008 and April 2015. The mean survival was 8.2 months. The overall survival rates at 6 months, 1 year, and 2 years were 60.3%, 31.5%, and 12.8%, respectively. Lung (59.5%) and breast (14.3) were the most common primary tumours, and the most common site for metastases was the cerebral hemisphere (77%) and the average volume was 10.35 cc (0.2-43.5). Significant survival factors were: age under 60 (P = .046), female (P < .001), breast cancer (P < .001), KPS > 80 (P = .001), SIR6 > 5 (P = .031), and GPA ≥ 2.5 (P = .003). Conclusions: Radiosurgery is an appropriate technique for the treatment of brain metastases, and the main prognostic factors include being age under 65, female, breast cancer, and good scores on Karnofsky, SIR, and GPA scales

Hematoma subdural crónico en pacientes muy ancianos / Chronic subdural haematomas in very elderly patients

Introducción. El hematoma subdural crónico (HSC) es una patología frecuente en los servicios de neurocirugía, y especialmente prevalente entre los pacientes de edad avanzada. El objetivo de este estudio es analizar las características demográficas, clínicas y radiológicas en una serie de pacientes mayores de 85 años afectados de un HSC. Pacientes y métodos. Realizamos un estudio retrospectivo sobre una serie de pacientes mayores de 85 años entre abril de 1986 y noviembre de 2015. Se recogieron las características clínicas (edad, sexo, comorbilidades, factores de riesgo, características radiológicas) y los resultados quirúrgicos (complicaciones fundamentalmente centradas en las recidivas y mortalidad). Analizamos las particularidades de este grupo de edad y su relación entre edad, sexo, grado clínico, tratamiento antiagregante o anticoagulante, arquitectura del hematoma, desplazamiento de la línea media y número de trépanos realizados con la mortalidad y recidiva del hematoma. Resultados. Analizamos 200 pacientes con una edad media de 88,5 años (rango 85-104), con una relación varón:mujer de 1:1,1. Se recogió antecedente traumático en 114 casos (57%) y estaban sometidos a terapia anticoagulante o antiagregante 71 pacientes (35,5%). Al ingreso, 114 pacientes (57%) tenían un buen estado clínico (grado 0-2 de Markwalder). El principal síntoma fue el deterioro cognitivo en 82 casos (41%). El HSC estaba localizado en el hemisferio izquierdo en 89 (44,5%), derecho en 78 casos (39%) y bilateral en los restantes 33 (16,5%). Se presentaron 59 complicaciones en 59 casos (29 recidivas) y el grado clínico de Markwalder se relacionó con unos mayores índices de complicaciones y mortalidad (p<0,0001). Conclusiones. El HSC es una patología frecuente en los pacientes muy ancianos. Clínicamente se manifiesta con deterioro cognitivo y déficit neurológico. La situación clínica al ingreso representó en nuestra serie un importante factor predictivo tanto de complicaciones como de mortalidad (AU)

Introduction. Chronic subdural haematoma (CSDH) is one of the most common neurosurgical conditions and is especially prevalent among elderly individuals. The objective of this study was to analyse the demographic, clinical and radiological findings, and surgical outcomes in a series of chronic subdural haematoma in patients older than 85 years. Patients and methods. A review was carried out on all patients over 85 years with CSDH treated in our neurosurgical service from April 1986 to November 2015. A record was made of the baseline patient characteristics (age, sex, comorbidities, known risk factors, imaging characteristics, and number of burr-holes) and surgical outcomes (complications, especially recurrences and mortality). An analysis was carried out on the special characteristics of these patients, as well as the relationships between gender, clinical grade, anti-platelet or anticoagulant therapy, internal architecture of the haematoma, and midline shift, with mortality and recurrence of the haematoma. Results. A total of 200 patients were included, with a mean age of 88.5 (range 85-104) years, and the male: female sex ratio was 1:1.1. History of injury was reported in 114 (57%) cases. Anti-platelet or anticoagulant therapy was being used by 71 (35.5%) patients. On admission, 114 patients (57%) were in satisfactory condition (Markwalder grades 0-2). The main symptom was behavioural disturbance in 82 (41%) cases. CSDH was left-sided in 89 (44.5%) patients, right-sided in 78 (39%) cases (39%), and bilateral in the remaining 33 (16.5%) cases). Postoperative complications were observed in 59 cases (29 recurrences). Preoperative Markwalder grade correlated significantly with recurrence rate and mortality (P<.0001). Conclusions. CSDH was a very common disease in very elderly patients. Behavioural disturbance and neurological deficits are the most common first symptom. Preoperative neurological status at admission is the most important factor in recurrences and mortality (AU)

Hematoma subdural crónico bilateral: análisis de una serie de 190 pacientes / Bilateral chronic subdural haematoma: Analysis of a series of 190 patients

Objetivos: Analizar las características clínicas, los factores de recidiva y el resultado quirúrgico de un grupo de pacientes con hematoma subdural crónico bilateral (HSCB) y compararlos con una serie de hematomas subdurales crónicos unilaterales (HSCU). Pacientes y métodos: Estudio retrospectivo que incluye a 1.523 pacientes, tratados quirúrgicamente durante un período de 30 años, de un hematoma subdural crónico. Los pacientes se dividieron en 2 grupos: el de estudio formado por 190 pacientes que presentaban un HSCB y el control formado por 1.333 pacientes que presentaban un HSCB. Resultados: La serie de estudio está formada por 126 varones (66,3%) y 64 mujeres (33,7%) con una edad media de 74,8±10,2 años. En el grupo control hay 870 varones (65,2%) y 463 mujeres (34,8%) con una edad media de 73,2% ± 12,1. El síntoma de inicio más frecuente fue el deterioro cognitivo en 63 pacientes (33,2%) en los bilaterales y en 416 (29,5%) en los unilaterales. Se produjeron 18 casos de recidiva (9,4%) en los bilaterales y 77 (5,7%) en los unilaterales (p = 0,027). La mortalidad fue de 10 casos (5,2%) en los bilaterales y de 55 (4%) en el grupo control. Se encontraron como factores significativos de recidiva: sexo masculino (p = 0,022), la ingesta de fármacos anticoagulantes/antiagregantes (p = 0,032) y la mala situación clínica al ingreso (p = 0,039). Conclusiones: El HSCB afecta de manera importante a los varones y la forma de presentación más habitual es la cefalea. Los factores más importantes que influyen en las recidivas son el sexo masculino, la ingesta de fármacos anticoagulantes/antiagregantes y la peor situación clínica al ingreso. Los índices de recidiva fueron significativamente superiores a los unilaterales

Objective: The aim of this study is to analyse the clinical findings and surgical results in a series of patients with bilateral chronic subdural haematoma (BCSDH), and compare the results with a series of patients treated for unilateral chronic subdural haematoma (UCSDH). Patients and methods: A retrospective study was performed on 1523 patients diagnosed and surgically treated for chronic subdural haematoma over a period of 30 years. Patients were divided into 2 groups: The study group consisting of 190 patients operated on for a BCSDH and the control group consisting of patients operated on for an UCSDH (1333 cases). Results: The patient series included 126 males (66.3%) and 64 females (33.7%), with a mean age at diagnosis of 74.8 ± 10.2. The control group consisted of 870 males (65.2%) and 463 women (34.8%), with a mean age of 73.2 ± 12.1. The most common presenting symptoms was cognitive impairment in 63 patients (33.2%) with BCSDH and 416 (29.5%) with UCSDH. Recurrence rates were 9.4% (18 patients) and 5.7% (77 patients) in unilateral and bilateral haematomas, respectively. The mortality was 10 patients (5.2%) with BCSDH and 55(4%) with UCSDH. Factors significantly related to recurrence in the univariate analysis were being male (P = .040), anticoagulant/antiplatelet therapy (P = .032), and poor neurological status at admission (P = .039). Conclusions: This study indicates that BCSDH is more frequent in males, and the most common presentation is headache. The most important factors influencing recurrences are being male, intake of anticoagulant-antiaggregant drugs, and worse clinical status at admission
