Crisis en urgencias: una vista a las características clínicas y terapéuticas a través de 122 pacientes / Seizures in the emergency service: the clinical and therapeutic characteristics of 122 patients

Introducción Las crisis epilépticas son un motivo frecuente de consulta en los servicios de urgencias hospitalarias. Llegar al diagnóstico correcto puede ser complejo, y es fundamental decidir cuándo y qué medicamento anticrisis (MAC) pautar. Nuestro objetivo es detallar las características de los pacientes que consultaron por este motivo en un hospital mediano. Pacientes y métodos Estudio observacional retrospectivo de todos los pacientes mayores de edad que consultaron en el servicio de urgencias del Hospital Universitario Lucus Augusti entre enero de 2022 y enero de 2023 con diagnóstico al alta de crisis epiléptica. Se registraron variables demográficas, los antecedentes, si era una primera crisis, el número de éstas, si se inició un MAC y cuál, el diagnóstico, qué pruebas se realizaron y si se interconsultó con la guardia de neurología. Resultados Se diagnosticó a 122 pacientes de crisis epilépticas en urgencias. El 50,8% eran mujeres. La media de edad fue de 69,8 años. Se solicitó valoración por neurología en un 47,6%. El 50,8% presentó una primera crisis. No se llegó al diagnóstico en un 46% de los casos, de los cuales sólo 10 fueron valorados por neurología. La etiología más frecuente fue la vascular. Se realizó un electroencefalograma en un 41,8%. El levetiracetam fue prácticamente el único fármaco utilizado cuando no se consultó con neurología. Conclusiones La valoración precoz de los pacientes con una primera crisis en urgencias por un especialista en neurología es determinante para el diagnóstico de epilepsia. Cuando no se interconsulta, casi siempre se pauta el mismo MAC. (AU)

INTRODUCTION Epileptic seizures are a common cause of admission in emergency services at hospitals. Performing the correct diagnosis can be difficult, and deciding when and which anti-seizure medication (ASM) to prescribe is critical. Our objective is to detail the characteristics of patients treated in a medium-sized hospital for this reason. PATIENTS AND METHODS A retrospective observational study was performed, including all the adult patients treated by the emergency service of the Lucus Augusti University Hospital between January 2022 and January 2023 with a diagnosis of epileptic seizure on discharge. The study recorded their demographic variables, history, whether it was their first seizure, the number of seizures, whether an anti-seizure medication was administered and which one, the diagnosis, the tests performed, and whether the patient was referred to the neurology service. RESULTS A total of 122 patients were diagnosed with epileptic seizures in the emergency service. 50.8% of the patients were women. The mean age was 69.8 years. Neurological assessment was requested for 47.6%. 50.8% presented their first seizure. No diagnosis was performed in 46% of the cases, of which only 10 were evaluated by the neurology service. The most common etiology was vascular. An electroencephalogram was performed on 41.8%. Levetiracetam was practically the only drug administered when the neurology department was not consulted. CONCLUSIONS Early evaluation of patients with their first seizure in the emergency service by a neurological specialist is crucial for the diagnosis of epilepsy. The same anti-seizure medication is almost always prescribed when no cross-consultation takes place. (AU)

Safety of Intravenous Thrombolysis for Acute Stroke in Patients with an Active Malignancy: Case Series and Review of the Literature.

INTRODUCTION: Evidence is scarce regarding the safety of alteplase for acute stroke in patients with an active malignancy. METHODS: We reviewed medical records for patients with both conditions treated at our institution over a 2-year period. RESULTS: Five patients were identified, of which only one developed an asymptomatic intracerebral haemorrhage, and no systemic bleedings occurred. Functional outcomes and stroke severity, as measured by National Institutes of Health Stroke Scale and modified Rankin Scale, were favourable upon discharge. CONCLUSION: In the absence of active bleeding or known malignancy of the central nervous system, intravenous alteplase seems a reasonable option for patients with an active cancer and acute stroke.

Utilidad de los estudios serológicos en los centros de Atención Primaria para el diagnóstico precoz de la enfermedad de Lyme / Usefulness of serological studies for the early diagnosis of Lyme disease in Primary Health Care Centres

Objetivo: Determinar la utilidad del diagnóstico precoz de la enfermedad de Lyme (EL) en los Centros de Atención Primaria (CAP) empleando el ELISA como técnica de cribado serológico. Métodos: Se realiza un estudio retrospectivo (2006-2013) consistente en la determinación mediante ELISA de la seropositividad a Borrelia de 2.842 personas consideradas en riesgo de padecer EL. Se estudia la relación entre el hábitat y la zona de residencia de las personas con seropositividad a Borrelia, según la procedencia de las muestras (CAP/Hospital). Resultados: El 15,2% de los sueros resultaron positivos frente a Borrelia spp. La seropositividad fue significativamente superior en las muestras remitidas desde los CAP que desde el Hospital y en los habitantes del rural y la montaña frente al área urbana y la meseta. El porcentaje de seropositividad se incrementó con el transcurso de los años. Los médicos de Atención Primaria detectaron mayor porcentaje de enfermos de Lyme en Fase I y tras la instauración del tratamiento no se observaron secuelas. Conclusiones: El papel del médico de atención primaria es primordial en el diagnóstico precoz de la EL, constatándose un mayor porcentaje de seropositivos entre las muestras remitidas desde los CAP con predominio del diagnóstico en Fase I de enfermedad y la resolución sin secuelas. La detección de anticuerpos específicos frente a Borrelia, mediante ELISA, es una prueba útil para el cribado de pacientes en riesgo de EL (AU)

Objective: The main aim of this study was to determine the usefulness of an early diagnosis of Lyme disease (LD) in Primary Health Care Centres (PHCC) using the ELISA test as serological screening technique. Methods: A retrospective study (2006-2013) was performed in order to determine the anti-Borrelia seropositivity in 2,842 people at risk of having LD. The possible relationship between the environment and the area of residence with anti-Borrelia seropositivity was also studied according to the origin of the specimens (PHCC/Hospital). Results: Overall, 15.2% of samples were positive to Borrelia spp. Seropositivity was significantly higher in samples sent by PHCC doctors than those sent by Hospital doctors. Seropositivity was significantly higher in rural than in urban populations and in those who live in mountainous or flat areas. The percentage of seropositivity has increased over the years. Conclusions: The role of the PHCC doctor is essential for achieving an early diagnosis of Lyme disease, as a higher percentage of seropositives was detected in samples submitted from PHCC. Furthermore, most early localised LD patients were diagnosed in PHCC, avoiding the appearance of sequelae. Therefore, detection of Borrelia specific antibodies using an ELISA assay is a useful screening test for patients at risk of LD (AU)

Manifestaciones articulares en enfermos de Lyme / Articular manifestations in patients with Lyme disease

Objetivos. Determinar el porcentaje de pacientes con clínica articular entre los enfermos de Lyme en el NO de España y conocer su evolución y respuesta al tratamiento. Pacientes. Se realizó un estudio retrospectivo (2006-2013) revisando las historias clínicas de los enfermos de Lyme con clínica articular. Se analizaron las manifestaciones clínicas, los datos de laboratorio, el tratamiento y la evolución de los enfermos. Resultados. Diecisiete de 108 pacientes confirmados como enfermos de Lyme (15,7%) presentaban clínica articular. De estos 17, el 64,7% presentó artritis, el 29,4% artralgias y el 5,9% bursitis. La rodilla fue la articulación más afectada. La clínica articular se asoció frecuentemente a manifestaciones neurológicas, dermatológicas o cardíacas. La mayoría de los pacientes estaban en fase iii. El 11,8% evolucionó a artritis crónica recidivante, aunque recibieron tratamiento adecuado. Conclusiones. En zonas con elevado riesgo de picadura por garrapatas, la presencia de clínica articular debe hacernos sospechar la posibilidad de una enfermedad de Lyme con objeto de establecer de forma precoz un tratamiento adecuado que evite secuelas (AU)

Objectives. To determine the percentage of Lyme patients with articular manifestations in NW Spain and to know their evolution and response to treatment. Patients. A retrospective study (2006-2013) was performed using medical histories of confirmed cases of Lyme disease showing articular manifestations. Clinical and laboratory characteristics, together with the treatment and evolution of the patients, were analysed. Results. Seventeen out of 108 LD confirmed patients (15.7%) showed articular manifestations. Regarding those 17 patients, 64.7%, 29.4% and 5.9% presented arthritis, arthralgia and bursitis, respectively. The knee was the most affected joint. Articular manifestations were often associated to neurological, dermatological and cardiac pathologies. Otherwise, most patients were in Stage III. The 11.8% of the cases progressed to a recurrent chronic arthritis despite the administration of an appropriate treatment. Conclusions. Lyme disease patients showing articular manifestations should be included in the diagnosis of articular affections in areas of high risk of hard tick bite, in order to establish a suitable and early treatment and to avoid sequels (AU)

[Clinical experience with lacosamide in Galicia: the GALACO study]. / Experiencia clinica con lacosamida en Galicia: estudio GALACO.

INTRODUCTION: Lacosamide is a sodium channel blocker antiepileptic drug authorized as an adjunctive therapy for focal seizures in adolescents and adults. AIM: To analyze the efficacy and safety of lacosamide in Galicia according to its use in daily clinical practice. PATIENTS AND METHODS: Retrospective observational study in patients who started treatment with lacosamide between January 2014 and June 2013 in 10 hospitals in Galicia, Spain. Its efficacy and safety at 3, 6 and 12 months after starting lacosamide was assessed. RESULTS: We included 184 patients with a mean age of 44.2 ± 17.4 years old; 56.5% (n = 104) were male; 173 patients constituted the efficacy population. Mean duration of epilepsy was 18.8 ± 15.5 years. Seizure frequency was 2.5 ± 1.6 episodes/month. After 12 months, 68.2% of patients (n = 118) had >= 50% improvement (responders) and among them, 54 (45.8% of responder patients) were seizure free. Twenty-three percent (n = 43) suffered from adverse events after 12 months, being dizziness (10.3%) and instability (3.3%) the most frequently reported. After the 12 month visit, 87.5% of patients (n = 161) continued treatment with lacosamide. CONCLUSIONS: Lacosamide provides a very good efficacy and safety profile for patients with focal refractory epilepsy. High percentage of responders may be related to a less refractory population compared to other daily clinical practice studies. It constitutes an attractive therapeutic option for the treatment of focal epilepsies.

Conforman la población de eficacia 173 pacientes. El tiempo medio de evolución de la epilepsia fue de 18,8 ± 15,5 años. La frecuencia de crisis era de 2,5 ± 1,6 episodios/mes. A los 12 meses, el 68,2% de los pacientes (n = 118) presentaba una mejoría igual o superior al 50% (pacientes respondedores) y, de ellos, 54 (el 45,8% de los respondedores) estaban libres de crisis. El 23,4% (n = 43) refirió efectos adversos a los 12 meses, principalmente mareos (10,3%) e inestabilidad (3,3%). Después de la visita de los 12 meses, continuaba con lacosamida el 87,5% de los pacientes (n = 161). Conclusiones. La lacosamida ofrece un perfil de eficacia y seguridad muy favorable para pacientes con epilepsia focal refractaria. El elevado porcentaje de respondedores podría atribuirse a una población de epilépticos menos refractarios que en otros estudios de práctica clínica. Constituye una opción terapéutica atractiva para el tratamiento de epilepsias de inicio focal.

Epidemiología de la enfermedad de Lyme en un área sanitaria del noroeste de España / Epidemiology of Lyme disease in a healthcare area in north-west Spain

Objetivo: Valorar la influencia de algunos factores de riesgo sobre la tasa de incidencia de la enfermedad Lyme y describir las principales manifestaciones clínicas de esta. Métodos: Se realizó un estudio retrospectivo sobre esta enfermedad (2006-2013), en una zona del noroeste de España, incluyendo solo los pacientes que cumplían los criterios de vigilancia epidemiológica de los Centers for Disease Control and Prevention de los Estados Unidos. Resultados: La tasa de incidencia varió entre 2,64 y 11,61 por 100.000 habitantes y año. Hubo diferencias significativas respecto al hábitat, la edad y la zona de residencia. Los pacientes presentaron manifestaciones neurológicas (67,59%), dermatológicas (47,22%), reumatológicas (15,74%) o cardiacas (13,88%), solas o combinadas. Conclusiones: El incremento de esta enfermedad en el noroeste de España y las diferencias observadas entre las distintas zonas de una misma área sanitaria hacen necesario plantear estudios epidemiológicos que permitan aumentar el índice de sospecha diagnóstica e implementar medidas de prevención eficaces (AU)

Objective: To evaluate the influence of some risk factors on the incidence rate of Lyme disease and the main clinical manifestations. Methods: A retrospective study of Lyme disease (2006-2013) was performed in north-west Spain; we included only patients who fulfilled the epidemiological surveillance criteria defined by the Centers for Disease Control and Prevention. Results: The incidence rate varied between 2.64 and 11.61/100,000 inhabitants/year. Significant differences were found in relation to habitat, age and area of residence. Patients showed neurological (67.59%), dermatological (47.22%), rheumatological (15.74%) and cardiac (13.88%) manifestations, alone or combined. Conclusions: Due to the increase of the disease in north-west Spain and the differences observed between the different areas, epidemiological studies are needed that increase the index of diagnostic suspicion and lead to the implementation of effective prevention measures (AU)

[Zonisamide in the preventive treatment of refractory migraine]. / Zonisamida en el tratamiento preventivo de la migraña refractaria.

INTRODUCTION: Chronic migraine refractory to preventive treatment is a common clinical situation in general neurology clinics. The aim is to analyse our experience with zonisamide in the preventive treatment of patients with frequent refractory migraine. PATIENTS AND METHODS: Those patients with no response or intolerance to topiramate and at least one more preventative received zonisamide. This drug was increased 25 mg per week up to 200 mg/day. The efficacy of zonisamide was evaluated in terms of 'response' (reduction in attack frequency below 50%) at the third month of treatment. RESULTS: Our series comprises a total of 172 patients, with ages ranging from 22 to 69 years. 85% were women. The final dosage of zonisamide was 50-200 mg/day, with the 100 mg/day being the most frequently administered dose. Zonisamide was efficacious (response) in 76 (44%) patients; response being excellent in 22 (13%). MIDAS score was reduced by 43.2%. Zonisamide was not tolerated by 27% of the patients, mainly due to subjective mental slowness or digestive symptoms. CONCLUSIONS: These results, obtained in a big sample of patients refractory or intolerant to topiramate and other preventatives, indicate that, at least in conditions of daily clinical practice, zonisamide, at relatively low dosages, is an option to be considered for the preventive treatment of patients with frequent migraine.

Introducción. La migraña crónica refractaria al tratamiento preventivo habitual es una situación frecuente en consultas de neurología. Se pretende analizar la experiencia con zonisamida en el tratamiento de pacientes con migraña frecuente refractaria. Pacientes y métodos. Aquellos pacientes sin respuesta o con intolerancia a topiramato y al menos otro fármaco preventivo para la migraña recibieron zonisamida. El fármaco se incrementó a razón de 25 mg/semana, hasta un máximo de 200 mg/día. La eficacia de la zonisamida se evaluó en términos de ‘respuesta’ (disminución en la frecuencia de las crisis al menos del 50%) al tercer mes del tratamiento. Resultados. Nuestra serie comprende 172 pacientes de entre 22 y 69 años. El 81% eran mujeres. Las dosis de zonisamida oscilaron entre 50 y 200 mg/día, y la dosis más frecuentemente administrada fue de 100 mg/día. La zonisamida mostró eficacia (respuesta) en 76 (44%) de los pacientes; la respuesta fue excelente en 22 (13%). La puntuación en el test de MIDAS se redujo en un 43,2%. Un 27% de los pacientes no toleró el fármaco, fundamentalmente por bradipsiquia subjetiva o clínica digestiva. Conclusiones. Estos resultados, obtenidos en un número amplio de pacientes refractarios o intolerantes a topiramato y otros fármacos, indican que, al menos en condiciones de práctica clínica, la zonisamida, en dosis relativamente bajas, es una opción que se debe considerar en el tratamiento preventivo del paciente con migraña frecuente

Strokes at time of disease diagnosis in a series of 287 patients with biopsy-proven giant cell arteritis.

Patients with giant cell arteritis (GCA) generally present with cranial ischemic manifestations that are directly related to vascular involvement. They may also experience strokes in the territory of the carotid or the vertebrobasilar artery. We conducted the current study to assess the frequency and predictors of strokes in general, and of vertebrobasilar stroke in particular, at the time of diagnosis in a series of 287 consecutive patients with biopsy-proven GCA diagnosed over a 27-year period at the single hospital for a well-defined population of northwestern Spain.During the study period, 8 (2.8%) patients had strokes (1 in the carotid and 7 in the vertebrobasilar territory) between the onset of symptoms of the disease and 4 weeks after the onset of corticosteroid therapy. Six of the 7 patients with vertebrobasilar stroke were men. In most cases the vertebrobasilar stroke occurred after the onset of corticosteroid therapy. Smoking history was more common among patients with vertebrobasilar stroke (p = 0.01). Patients with vertebrobasilar stroke more commonly had permanent visual loss due to arteritic involvement of ophthalmic branches derived from the internal carotid (3/7; 42.9%) than the rest of GCA patients (33/280; 11.8%) (p = 0.05). Patients with strokes had higher hemoglobin values (13.2 +/- 1.5 g/dL) than patients without (11.7 +/- 1.6 g/dL) (p = 0.009). Moreover, only 1 (14.3%) of the 7 patients with vertebrobasilar stroke had anemia compared to 157 (56.1%) of the remaining 280 patients (p = 0.05). The best predictors of stroke were permanent visual loss (odds ratio [OR], 5.42) and arterial hypertension (OR, 5.06). In contrast, women (OR, 0.10) and patients with anemia at the time of disease diagnosis (OR, 0.11) had a significantly reduced risk of suffering strokes. Smoking history was the best positive predictor of vertebrobasilar stroke (OR, 5.22). In contrast, a reduced risk of suffering vertebrobasilar strokes was found in individuals who had anemia at the time of GCA diagnosis (OR, 0.13).Results of the current study show an increased risk of strokes, in the vertebrobasilar territory in particular, at the time of GCA diagnosis. Patients with biopsy-proven GCA and traditional cardiovascular risk factors or permanent visual loss have an increased risk of suffering strokes. Results also suggest a potential protective role of anemia against the development of these cerebrovascular complications.

Two coincidental neurological complications as a presenting form of infectious endocarditis.

A 46-year-old man with two consecutive neurological events (an ischemic stroke and an intracerebral hemorrhage) is presented. Streptococcus bovis biotype I was found in blood cultures and echocardiography showed native mitral valve mobile vegetations. The patient died due to the extension of intracerebral hemorrhage.

Ischemic heart disease in patients from Northwest Spain with biopsy proven giant cell arteritis. A population based study.

OBJECTIVE: To assess the incidence, mortality, and predictors of ischemic heart disease (IHD) in patients from the Lugo region of Northwest Spain with biopsy-proven giant cell arteritis (GCA). METHODS: Retrospective study of patients with biopsy-proven GCA diagnosed from 1981 to 2001 at the single hospital for a population of 250,000 people. A survival analysis was performed. Hazard ratios and standardized mortality ratio (SMR) as well as predictors of IHD in patients with biopsy-proven GCA were also assessed. RESULTS: Nineteen (9%) of the 210 patients with biopsy-proven GCA diagnosed during the period of study had IHD. The incidence of IHD in patients with GCA was 12.6/1000 person-years at risk (95% CI 6.9-21.0). During the study period 1981-2000 the population aged > or = 50 years in Lugo was roughly 100,000, and the mortality rate due to IHD in patients with GCA for that population was 8/100,000. The SMR in patients with GCA due to IHD was 1.62 (95% CI 0.70-3.20). Mortality in patients with GCA who had IHD was higher than in those patients without IHD (age and sex adjusted hazard ratio 2.81, 95% CI 1.51-5.21; p = 0.001). Age (hazard ratio 1.15), hypertension (hazard ratio 2.51), and abnormal temporal artery on physical examination (hazard ratio 0.36) at the time of diagnosis of GCA were the best predictors of IHD over the followup period in patients with biopsy-proven GCA. CONCLUSION: Our observations suggest that mortality due to IHD in patients from Lugo with GCA is not much higher than that reported in the Spanish population aged 50 years and older. However, mortality in patients with GCA with IHD is higher than in GCA patients without IHD.

Aortic aneurysm and dissection in patients with biopsy-proven giant cell arteritis from northwestern Spain: a population-based study.

Most classical manifestations of giant cell arteritis (GCA) are the result of occlusive vascular involvement. However, unlike ischemic manifestations, aortic aneurysmal disease in patients with GCA has been less well described. We assessed the incidence and predictors of aortic aneurysm and dissection in patients with biopsy-proven GCA from the Lugo region of northwestern Spain and compared the results with those in a 2003 report from Olmsted County, MN. We performed a retrospective study of biopsy-proven GCA patients diagnosed from 1981 to 2001 at the single hospital for a well-defined population of almost 250,000 people. Twenty (9.5%) of the 210 biopsy-proven GCA patients diagnosed during the study period developed aortic aneurysmal disease. Sixteen of the 20 patients had thoracic aneurysms and 6 had abdominal aneurysms. The incidence of aortic aneurysm and/or dissection in Lugo (18.9 per 1000 person years at risk) was similar to that reported in Olmsted County (18.7 per 1000 person years at risk). Hypertension (hazard ratio: 4.73) and polymyalgia rheumatica with a marked acute inflammatory response at the time of diagnosis of GCA (hazard ratio: 3.71) were the best predictors of aortic aneurysmal disease. Our present observations suggest that a severe inflammatory response associated with hypertension at the time of diagnosis of GCA may promote the development of aortic aneurysmal disease. GCA patients having these features should be monitored for the existence of aortic aneurysm and dissection.
