Delayed Neurological Improvement After Full Endovascular Reperfusion in Acute Anterior Circulation Ischemic Stroke.

Background and Purpose: We aimed to determine the prevalence and predictors of delayed neurological improvement (DNI) after complete endovascular reperfusion in anterior circulation acute ischemic stroke (AIS). Methods: Retrospective analysis of an online multicenter prospective reperfusion registry of patients with consecutive anterior circulation AIS treated with endovascular thrombectomy (EVT) from January 2018 to June 2019 in tertiary stroke centers of the NORDICTUS (NORD-Spain Network for Research and Innovation in ICTUS) network. We included patients with AIS with a proximal occlusion in whom a modified Thrombolysis in Cerebral Infarction 3 reperfusion pattern was obtained. DNI was defined if, despite absence of early neurological improvement during the first 24 hours, patients achieved functional independence on day 90. Clinical and radiological variables obtained before EVT were analyzed as potential predictors of DNI. Results: Of 1565 patients with consecutive AIS treated with EVT, 1381 had proximal anterior circulation occlusions, 803 (58%) of whom achieved a modified Thrombolysis in Cerebral Infarction 3. Of these, 628 patients fulfilled all selection criteria and were included in the study. Mean age was 73.8 years, 323 (51.4%) were female, and median baseline National Institutes of Health Stroke Scale was 16. Absence of early neurological improvement was observed in 142 (22.6%) patients; 32 of these (22.5%) achieved good long-term outcome and constitute the DNI group. Predictors of DNI in multivariable-adjusted logistic regression were male sex (odds ratio, 6.4 [95% CI, 2.1­22.3] P=0.002), lower pre-EVT National Institutes of Health Stroke Scale score (odds ratio, 1.4 [95% CI, 1.2­1.5], P<0.001), and intravenous thrombolysis (odds ratio, 9.1 [95% CI, 2.7­30.90], P<0.001). Conclusions: One-quarter of patients with anterior circulation AIS who do not clinically improve within the first 24 hours after complete cerebral endovascular recanalization will achieve long-term functional independence, regardless of the poor early clinical course. Male sex, lower initial clinical severity, and use of intravenous thrombolysis before EVT predicted this clinical pattern.

Nutritional profile of multiple sclerosis / Perfil nutricional de la esclerosis múltiple

Background: multiple sclerosis (MS) is an inflammatory, neurodegenerative disease of the central nervous system. Weight loss and malnutrition are prevalent in advanced stages of MS. Objective: the aim of this study was to define the nutritional profile in moderate-advanced MS (especially by documenting malnutrition) and its evolution. Methods: a case-control study was designed; cross-sectional observational study was complemented by a 12-month prospective longitudinal observational study of MS patients. Nutritional status was evaluated by collecting clinical, anthropometric, dietary and analytical data. Results: one hundred and twenty-four patients with MS and 62 controls were recruited; 8% of the patients were malnourished or at risk of malnutrition. Only MS patients with advanced disability needed nutritional support. During the follow-up, five patients died and four of them received nutritional support. Conclusions: malnutrition was unusual in our sample of patients with moderate-advanced MS. The need for nutritional support is related to dysphagia in patients with advanced neurological disability. The nutritional status of patients with moderate-advanced MS is defined by a tendency to overweight and by the decrease in basal energy expenditure and handgrip strength test in relation to the loss of muscle mass. The deficient intake of polyunsaturated fatty acids, fiber and vitamin D is exacerbated in the evolution of the disease

Introducción: la esclerosis múltiple (EM) es una enfermedad inflamatoria y neurodegenerativa del sistema nervioso central. La pérdida de peso y la malnutrición son frecuentes en fases avanzadas de la EM. Objetivo: el objetivo de este estudio fue definir el perfil nutricional de la EM en estadio moderado-avanzado (especialmente, documentando la malnutrición) y su evolución a 12 meses. Métodos: se realizó un estudio de casos-controles; el estudio observacional transversal se complementó con un estudio observacional longitudinal prospectivo a 12 meses de los pacientes con EM. El estado nutricional se evaluó mediante la recogida de datos clínicos, antropométricos, dietéticos y analíticos. Resultados: se incluyeron en el estudio 124 pacientes con EM y 62 controles. El 8% de los pacientes estaban desnutridos o en riesgo de desnutrición. Solo los pacientes con EM con discapacidad avanzada necesitaban soporte nutricional. Durante el seguimiento, cinco pacientes fallecieron y cuatro de ellos estaban recibiendo soporte nutricional. Conclusiones: la desnutrición es infrecuente en nuestra muestra de pacientes con EM moderada-avanzada. La necesidad de apoyo nutricional está relacionada con la disfagia en pacientes con discapacidad neurológica avanzada. El estado nutricional de los pacientes con EM moderada-avanzada se define por una tendencia al sobrepeso y por valores bajos en el gasto energético basal y en la dinamometría manual en relación con la pérdida de masa muscular. La ingesta deficiente de ácidos grasos poliinsaturados, fibra y vitamina D se acentúa en la evolución de la enfermedad

Isolated deafness in multiple sclerosis patients.

Isolated cranial nerve involvement in multiple sclerosis (MS) patients is not frequent. Deafness is considered to be uncommon in MS patients. We have reviewed the sensorineural hearing loss episodes that had been thoroughly investigated in our hospital in the last 5 years. We present three cases of sensorineural hearing loss in patients with MS and compare them with other previously reported and discuss this uncommon symptom. The cases that we present were firstly evaluated by an otolaryngologist. A lesion is seen at the root-entry zone of the eighth cranial nerve in only one case, but no lesions are seen in the other cases. A retrocochlear demyelinating disorder was demonstrated in the two patients in whom brainstem auditory evoked potentials were performed. All patients recovered at least partially their hearing functions.

Mechanical endovascular procedure for the treatment of acute ischemic stroke caused by total detachment of a papillary fibroelastoma.

Papillary fibroelastomas (PFEs) are rare cardiac tumors. Despite their benign nature, they are associated with a high risk of embolic complications including stroke. Endovascular treatment has been reported as a safe procedure in patients with myxoma, the most common type of primary cardiac tumor. A case of ischemic stroke due to embolization of a PFE successfully treated with a single pass of a retrievable stent is described. A 64-year-old patient with a right middle cerebral artery syndrome was treated with an intravenous and endovascular protocol as a revascularization procedure. Mechanical thrombectomy resulted in total recanalization with clinical improvement. Histological examination of the clot showed pathological features of a typical PFE. The endovascular treatment was safe and effective. With mechanical embolectomy it is possible to obtain and analyze pathological specimens, enabling the diagnosis of uncommon strokes.
