Thrombectomy with embed aspiration in acute ischaemic stroke.

BACKGROUND: In addition to stent retrievers, direct aspiration has become a reasonable thrombectomy strategy. OBJECTIVES: We carried out the thrombectomy by guiding the aspiration catheter fully over the clot and performing immediate manual aspiration; we call this procedure "embed aspiration". METHODS: In this prospective, non-randomised, single-centre study, we included all patients treated at a high volume-of-care stroke centre between 2017 and 2018 for the TRIANA (Thrombectomy in Andalusia using Aspiration) registry. Thrombectomy was carried out by embed aspiration. Patients were classified according to the success (eTICI 2b67-2c-3) or failure (eTICI 0-1-2a-2b50) of the procedure. Baseline clinical data and outcomes were compared, and multivariate analysis was performed. RESULTS: The embed aspiration technique was used in 370 patients. Treatment was successful in 90.3% of patients. Mean puncture-to-recanalisation time was 25 minutes. The overall rate of good outcomes (mRS 0-2) at 3 months was 64%. CONCLUSIONS: This study supports real-life evidence that standardised embed aspiration may be an alternative to stent retrievers for thrombectomy.

Benefits in quality of life following an obstructive sleep apnea screening and treatment program in patients with acute ischemic stroke. / Beneficios en la calidad de vida de un programa de cribado y tratamiento de apnea obstructiva del sueño en pacientes con ictus isquémico agudo.

INTRODUCTION: Obstructive sleep apnea (OSA) has been proposed as a factor that worsens stroke prognosis. Our aim was to determine if an OSA intervention could improve quality of life (QOL, first objective) and modified Rankin score (mRS, second objective). PATIENTS AND METHODS: The intervention group of this quasi-experimental study included patients with acute ischemic stroke <72 hours who underwent polygraphy and Continuous Positive Airway Pressure (CPAP) and hygienic-dietary measures if required. The control group followed routine clinical practice. The Short Form 36 Health Survey (SF-36) and mRS were applied at the sixth month after stroke in both groups. RESULTS: Fifty-five vs. sixty-two patients were included in the intervention and control group respectively. In the intervention group, 64.71% of patients accepted the proposed CPAP (16 cases with a good adherence). An improvement in SF-36 items was detected in the intervention group: physical functioning (p = 0.008), role physical (p = 0.002), bodily pain (p = 0.008), general health (p <0.001), vitality (p = 0.001) and role emotional (p = 0.015). In a per-protocol analysis, all these improvements were verified in the group of patients treated with good CPAP adherence (p < 0.05 in all the same SF-36 items). The percentage of patients with physical component summatory = 50 was higher in the intervention group (p = 0.003). There were no differences in the median of mRS (p = 0.262). CONCLUSIONS: Although more evidence is needed, a significant improvement in QOL was suggested after our OSA intervention, particularly in patients with good CPAP adherence.

TITLE: Beneficios en la calidad de vida de un programa de cribado y tratamiento de apnea obstructiva del sueño en pacientes con ictus isquémico agudo.Introducción. La apnea obstructiva del sueño (AOS) se ha propuesto como un factor de mal pronóstico en el ictus. Pretendemos determinar si una intervención sobre la AOS puede mejorar las escalas de calidad de vida (primer objetivo) y de discapacidad (segundo objetivo). Pacientes y métodos. El grupo de intervención de este estudio cuasi experimental incluye a pacientes con ictus isquémico agudo menor de 72 horas de evolución a quienes se les realizó poligrafía, así como presión positiva continua en las vías aéreas (CPAP) y medidas higienicodietéticas si se requerían. En el grupo de control se siguió la práctica clínica habitual. Se aplicaron las escalas Short Form 36 Health Survey (SF-36) y modified Rankin Score (mRS) en el sexto mes del ictus en ambos grupos. Resultados. Se incluyó a 55 y a 62 pacientes en el grupo de intervención y en el de control, respectivamente. En el grupo de intervención, el 64,71% de los pacientes aceptó la CPAP indicada (16 casos con buena adhesión). Se detectó una mejoría en los ítems de la escala SF-36 en el grupo de intervención: funcionamiento físico (p = 0,008), rol físico (p = 0,002), dolor corporal (p = 0,008), salud general (p menor de 0,001), vitalidad (p = 0,001) y rol emocional (p = 0,015). En un análisis por protocolo, todas estas mejorías se comprobaron en el grupo de pacientes tratados con CPAP con buena adhesión (p menor de 0,05 en todos los ítems de la SF-36). El porcentaje de pacientes con el sumatorio del componente físico = 50 fue más alto en el grupo de intervención (p = 0,003). No había diferencias en la mediana de la mRS (p = 0,262). Conclusiones. Aunque se necesitan más evidencias, nuestro estudio sugiere una mejoría significativa de la calidad de vida tras nuestra intervención en la AOS, especialmente en pacientes con buena adhesión a la CPAP.

Retraso en la administración de tratamiento trombolítico en el ictus minor / Delayed administration of thrombolytic therapy in minor stroke

Introducción: Se considera ictus minor a aquel que se presenta con escasos síntomas; sin embargo, hasta un 40% presenta discapacidad a largo plazo. La tasa de trombólisis en estos pacientes también es inferior a la del resto de ictus. En este estudio se pretende explorar si existen diferencias en los tiempos de atención en la trombólisis intravenosa en los pacientes con ictus minor. Material y métodos. Revisión retrospectiva de los ictus tratados con trombólisis intravenosa en nuestro centro y análisis comparativo de los tiempos de asistencia entre ictus minor y el resto. Resultados: Se encontraron tiempos más alargados en los casos de ictus minor en cuanto al tiempo puerta-tomografía computarizada y puerta-aguja. No fue así, sin embargo, para el tiempo desde el inicio de los síntomas hasta la llegada al hospital. Conclusiones: La presencia de escasos síntomas en el ictus minor puede hacer difícil su reconocimiento y podría ser un motivo de retraso en el tratamiento. La formación entre el personal que atiende a estos pacientes es fundamental para mejorar este aspecto.(AU)

Introduction: Minor strokes are considered to be those that present with few symptoms, although up to 40% of them entail long-term disability. The rate of thrombolysis in these patients is also lower than in other strokes. The aim of this study is to explore whether there are any differences in intravenous thrombolysis care times in minor strokes. Patients and methods: We conducted a retrospective review of strokes treated with intravenous thrombolysis at our centre and a comparative analysis of the care times in minor strokes and in the other types. Results: Longer times were found in minor strokes in terms of door-to-CT scan and door-to-needle time. This was not the case, however, for the time from the onset of symptoms to arrival at the hospital. Conclusions: The presence of few symptoms in minor strokes can make them difficult to recognise and could be a reason for delaying treatment. Training among staff caring for these patients is essential to improve this aspect.(AU)

Revascularización carotídea con stent: implicaciones clínicas y para el procedimiento de la presencia de una lesión suboclusiva / Carotid artery stenting: clinical and procedural implications for near-occlusion stenosis

Introducción y objetivos: La conveniencia del implante de stent en lesiones carotídeas suboclusivas es un tema controvertido. Nuestro trabajo valoró las implicaciones clínicas y de procedimiento de la revascularización de lesiones carotídeas suboclusivas. Métodos: Se incluyó a 205 pacientes con enfermedad carotídea revascularizados con stent: los pacientes con lesiones suboclusivas (n = 54) fueron comparados con el resto de la población (n = 151). Resultados: No hubo diferencias entre grupos para la edad, el sexo y la tasa de pacientes sintomáticos (que constituían 3 cuartas partes de la población). El implante de stent en lesiones suboclusivas cursó con una alta tasa de éxito (96%), similar al resto de las lesiones (98%). La revascularización de las lesiones suboclusivas condicionó un mayor uso de protección proximal (54% vs. 20,5%, p < 0,001) y necesidad de predilatación (33% vs. 17%, p = 0,01). El abordaje de lesiones suboclusivas ocasionó un mayor desprendimiento de placa, manifestado por una mayor tasa de material embólico extraído (18,5% vs. 7%, p = 0,01) y de lesiones isquémicas cerebrales periprocedimiento (47% vs. 31%, p = 0,07). A los 30 días de la revascularización, la tasa de eventos neurológicos (muerte, ictus mayor, ictus menor) mostró tendencia a ser mayor para el grupo con lesiones suboclusivas (9,2% vs. 3,2%, p = 0,08). Conclusiones: La revascularización con stent de lesiones carotídeas suboclusivas presenta una alta tasa de éxito de procedimiento; sin embargo, su mayor carga de placa ocasiona un superior porcentaje de lesiones isquémicas cerebrales, y de eventos neurovasculares en el primer mes (AU)

Introduction and objectives: The advisability of implanting a stent in carotid near-occlusion stenosis is a controversial topic. We have assessed procedural and clinical implications of stent implantation for carotid artery disease with near occlusion. Methods: We included 205 patients who underwent carotid artery revascularisation with a stent. The group of patients with near-occlusion stenosis (n=54)was compared to the rest of the population (n=151). Results: No differences were found between groups for age, sex, and the percentage of symptomatic patients (three-quarters of the population). Carotid stent revascularisation for near-occlusion stenosis presented a high procedural success rate (96%) similar to that of revascularisation processes for other lesions (98%). Stenting in cases of near-occlusion stenosis required increased use of proximal protection (54% vs. 20.5%, P<.001) and predilation (33% vs. 17%, P=.01). The process to repair near-occlusion stenosis cause increased detachment of plaque, as shown by higher percentages of macroscopic plaque captured by protection devices (18.5% vs. 7%, P=.01) and of perioperative ischaemic brain lesions (47% vs 31%, P = .07). At 30 days of follow-up, the tendency toward adverse neurological events (death, major and minor stroke) was higher in the near-occlusion group (9.2% vs. 3.2%, P=.08). Conclusions: Stent revascularisation for near-occlusion carotid stenosis has a high procedural success rate; however, its higher plaque load was responsible for the increased rate of ischaemic brain lesions and adverse neurovascular events at 30 days post-procedure (AU)

[Autosomal dominant compelling helio-ophthalmic outburst syndrome (photic sneeze reflex). Clinical study of six Spanish families]. / Síndrome de estornudos heliooftálmicos compulsivos autosómico dominante (reflejo fótico de estornudo). Estudio clínico de seis familias españolas.

INTRODUCTION: Sneeze is an ubiquitous phenomenon that happens to everyone. In spite of this, little attention has been paid to it, among medical literature in general, and even less in neurologic texts. A curious entity, called autosomal dominant compelling helio-ophthalmic outburst syndrome, has been scarcely described in the scientific literature. This reflex appears when subjects are exposed suddenly to intense sunlight and it consists of long incoercible sneeze bursts. There are no publications on this subject among the spanish literature.and intensity increase with time. OBJECTIVE: To study the clinical and physiological features of the reflex in Spanish families. PATIENTS AND METHOD: Affected subjects were identified by personal interview and given a questionnaire drawn up for this study. Besides, they were instructed to give the questionnaire to their relatives.and intensity increase with time. RESULTS: All the six families showed a high-penetrance, autosomal dominant inheritance. The reflex had a high consistency, a latency about 3 seconds, an intersneeze interval of 2 seconds and a frequency of 2-3 sneezes/ burst. Refractory period was long.and intensity increase with time. DISCUSSION: Our study suggest a higher consistency, shorter latency and lower age of onset of the reflex in our patients than general population, and that frequency and intensity increase with time.

Intrathecal IgG synthesis: marker of progression in multiple sclerosis patients.

OBJECTIVES: We study the power of IgG synthesis value as a marker of disease activity in multiple sclerosis (MS). MATERIAL AND METHODS: Link index was calculated in 202 MS patients. Time between first, second and third attack and progression index (PI) were compared in patient with normal (NLI) high (HL) or very high Link index (VHLI). RESULTS: Secondary progressive (SP) patients had a higher LI than relapsing-remitting (RR) and primary progressive (PP) courses (1.10 +/- 0.5 for SP vs 0.86 +/- 0.5 for RR and 0.81 +/- 0.5 for PP, P=0.01 and 0.03, respectively). Having a HLI in MS RR and SP patients has no time effect in the development of the second and third attack. PI was higher in patients with VHIL (0.67 +/- 0.7) vs patients with NLI (0.42 +/- 0.4, P=0.008) and with HLI (0.39 +/- 0.3, P=0.001). CONCLUSIONS: This study confirmed that LI is a good marker of subsequent progression of MS.

[Clinical features of familial multiple sclerosis in Spain]. / Características clínicas de la esclerosis múltiple familiar en España.

INTRODUCTION: Multiple sclerosis (MS) is a demyelinating and inflammatory disease of the central nervous system (CNS) with a clear proved genetic susceptibility. The real frequency and clinical features of familial MS is although not well established in Spain. OBJECTIVE: We studied the clinical and CSF features of familial MS (FMS) patients in comparison with the rest of our patients. PATIENTS AND METHODS: We reviewed 308 definite MS patients looking for patients with other familial members with MS. We analyzed clinical characteristics (age, age at onset, sex, evolution time, evolution course, symptoms at onset, disability measured by EDSS scale) and IgG synthesis measured by Tibbling-Link index. RESULTS: We found 23 patients (10 men and 13 women) in 18 independent families with at least other family member diagnosed of definite MS (7.47% of our total MS population). Age and age at onset were no different from non FMS cases. The clinical course was relapsing-remitting in 21 out of 23 FMS cases and secondary progressive in two. No primary progressive cases were found among FMS. At onset the symptom most frequently found in FMS was optic neuritis. Mean EDSS score was lower in FMS cases in comparison with the rest of cases. Link index was increase in 93.7% of patients with FMS. CONCLUSION: In comparison with non familiar forms FMS patients in Spain, present more often remitting courses, are less disabled, optical neuritis is more frequently seen as onset symptom and IgG synthesis is more often increased.

[Evolution and adverse effects in patients with remittent-recurrent multiple sclerosis treated with interferon beta 1b. The influence of patient's weight and height]. / Evolución y efectos adversos en pacientes con esclerosis múltiple remitente-recidivante tratados con interferón beta 1b. Influencia del peso y la talla de los enfermos.

BACKGROUND: The aim of the present study was to determine whether the adverse effects (AE) of interferon beta 1b (IFNb-1b) are related to patient weight, height and body surface area. Moreover, whether the basal incapacity and/or some of these AE may be related to the evolutive prognosis were also studied. METHODS: Twenty-nine females and 14 males with remittent-recurrent multiple sclerosis treated with IFNb-1b were studied. The clinical data and the AE, were compared with the number of outbreaks and the progression of incapacity over the first year of treatment in patients with high weight, height and body surface area with respect to those under the mean. RESULTS: Although the presence of fever was similar in the two groups during the first month (8/19 in the high weight patients and 11/24 in the low weight group), in the following months, overall, the low weight patients continued to present fever. Fever during the first month was associated with a lower number of outbreaks at one year of evolution (0.04 +/- 0.1, n = 19 vs 0.30 +/- 0.5, n = 24; p = 0.04). Furthermore, the patients with lesser incapacity presented a better evolution than those with more incapacity, particularly at 2 years (0.21 +/- 1.3 vs 1.36 +/- 0.9; p = 0.05). CONCLUSIONS: During the first month of treatment fever is very frequent in all the patients regardless of weight and fever was correlated with a lower number of outbreaks at one year of evolution. From the third month fever was less frequent in the lower weight patients group.

[Familial cerebral cavernomatosis associated with cutaneous angiomas]. / Cavernomatosis cerebral familiar asociada a angiomas cutáneos.

UNLABELLED: OBJECTIVE, PATIENTS AND METHOD: We present a genealogical study of a person with familial cerebral cavernomatosis (CCF) discovered following study of a man who presented with status epilepticus at the age of 35 years. This had also affected another three members of the family consisting of a total of 43 persons, studied over six generations. RESULTS: In the family members studied we did not find cavernomas at other sites but there were dermatological lesions whose relation to cerebral cavernomas (CC) is discussed. CCs are the second commonest type of cerebral vascular malformations. Their major clinical features are epilepsy and cerebral haemorrhage. There are two forms of CC: a sporadic form with single lesions and a familial form with multiple lesions. Although the condition has been recognized since 1854, very little is known about it. Recently a gene causing the familial form has been found on chromasome 7. CONCLUSIONS: We discuss the clinical findings in this family with relation to descriptions in the literature. We emphasize the importance of MR in diagnosis of the condition and for detection of asumptomatic carriers. We consider a possible relationship between these findings and genes which have been mapped, and in view of recent genetic data, the hypothesis of a possible Spanish ancestor with the condition.
