[Migraine with aura, right-to-left shunt and frequency of seizures]. / Migraña con aura, shunt derecha-izquierda y frecuencia de crisis.

INTRODUCTION: The high prevalence of patent foramen ovale in migraine with aura (MWA) seems to be well established; yet, the possible relation between the magnitude of the right-to-left shunt (RLS) and MWA is not so clear. As a hypothesis, if the RLS played a precipitating role, subjects with a larger degree of shunt might experience a higher number of seizures. We examine this possible relationship between the magnitude of the shunt and the incidence of seizures. PATIENTS AND METHODS: We examined a series of 72 patients with MWA to obtain the frequencies of seizures (dividing them into three groups of increasing frequency), history and precipitating factors. The presence and magnitude of the RLS were later determined by means of transcranial Doppler ultrasonography, following a method that had previously been validated. Univariate analysis was then used to evaluate the possible association between the magnitude of the shunt and the frequency of seizures. RESULTS: The mean age was 36 years. RLS appeared in 44 patients (61.1%) and followed a 'shower/curtain' pattern in 38% of cases. Frequency of seizures was low in 27%, medium in 45% and high in 27% of patients. Frequency was not associated with the magnitude of the shunt even when only high-frequency cases were considered. High frequency was associated, however, with certain precipitating factors. CONCLUSIONS: Our study confirms the existence of a high prevalence of RLS in patients with MWA, but no association was found between the magnitude of the shunt and the frequency of the seizures. As discussed here, these findings are partly at odds with a 'threshold' type of association or mechanism that precipitates seizures.

[Use of extra-hospital emergency systems in the treatment of acute stroke in the region of Murcia. Possible repercussions on the urgent care of stroke patients]. / Utilización del sistema de emergencias extrahospitalario en el tratamiento del ictus agudo en la región de Murcia. Posible repercusión en la asistencia sanitaria urgente del ictus.

AIM: To examine the use of extra-hospital emergency systems in the urgent care of stroke patients in our region and their influence on the time required to reach hospital, the time needed to perform an urgent computerised axial tomography (CAT) scan and the delay in receiving attention from the specialist. PATIENTS AND METHODS: Samples were collected from 232 stroke patients out of the total number admitted to our hospitals. Data about the stroke were collected prospectively, and included the arrival time, the time required to perform the CAT scan and the time the specialist devoted to attending the patient. Data were also gathered about the different extra-hospital transport and emergency systems. A statistical analysis was performed to determine the effect of using the extra-hospital emergency procedures on the different variables. RESULTS: A total of 53.6% of patients arrived within the first three hours. 38.7% went straight to hospital, 25% visited extra-hospital Emergency Services first, and 18.5% made a prior visit to Primary Care. 51.5% found their own way to the hospital and 46.7% arrived by ambulance. Mean time taken to perform an urgent CAT scan: 190.4 minutes; mean time required for specialist attention: 25.65 hours. The only statistically significant relation was the use of extra-hospital emergency systems and health care transport according to the type of stroke: both were more likely to be used in cases of haemorrhagic stroke. CONCLUSIONS: In hospitals in the Murcia region, the use of the extra-hospital emergency system and the means of transport utilised do not affect the time stroke patients take to reach hospital or the time needed to perform an urgent CAT scan or the delay in receiving attention from a specialist; the aetiology of the stroke does, however, influence the use of such services.

Objetivo. Utilización en nuestra región de los sistemas de urgencias extrahospitalarias en la atención urgente del ictus y su influencia en el tiempo de llegada al hospital, el de realización de la tomografía axial computarizada (TAC) urgente y demora de la atención por el especialista. Pacientes y métodos. Se recogieron muestras de 232 pacientes con ictus del total de los ingresados en nuestros hospitales. Prospectivamente se recogieron datos sobre el ictus, con inclusión de los tiempos de llegada, tiempo de realización de la TAC y tiempo de atención por el especialista. Se recogió el uso delos distintos sistemas de urgencias y transporte extrahospitalarios. Estadísticamente se analizó la influencia del uso de los dispositivos de urgencia extrahospitalarios en las distintas variables recogidas. Resultados. 53,6% de los pacientes llegaron en las tres primeras horas. 38,7% acudieron directamente al hospital, el 25% acude primero al Servicio de Urgencias extrahospitalarias y 18,5% consulta previamente con Asistencia Primaria. El 51,5% llegaron por sus propios medios y el 46,7% en ambulancia. Tiempo medio de TAC urgente: 190,4 minutos; tiempo medio de atención por el especialista:25,65 horas. La única relación estadísticamente significativa fue el uso del sistema de urgencias extrahospitalarias y transporte sanitario según el tipo de ictus, con más tendencia a utilizarlos en los ictus hemorrágicos. Conclusiones. En los hospitales de Murcia, el uso del sistema de urgencias extrahospitalarias y el medio de transporte empleado no influyen en el tiempo de llegada del ictus al hospital, en el tiempo de realización de TAC urgente ni en la demora de atención por el especialista, y sí influye en la utilización de dichos servicios la etiología del ictus (AU)

[Descriptive study of behavioural disorders in mild cognitive impairment]. / Estudio descriptivo de los trastornos conductuales en el deterioro cognitivo leve.

INTRODUCTION: Mild cognitive impairment (MCI) is defined as an abnormality in cognitive function not provoking a noticeable disability in activities of daily living in the affected person. In a group of patients with MCI, we propose to observe and to quantify the presence of behavioral disorders, using the neuropsychiatric inventory (NPI). PATIENTS AND METHODS: NPI is a known instrument in evaluation of this kind of disorders in patients with dementia, and it is a semi structured interview with a relevant informer or relative to the patient. NPI was applied to a series of 100 cases (61 women and 39 men) of MCI, diagnosed as usual in our settings. Mean age was 74.3 +/- 10 years, and mean MEC (Spanish modified version of MMSE) 25.57 +/- 4.2 (over a maximum of 35 points). RESULTS: Most prevalent disorder was depression, in 36 % of cases, and other frequent findings were irritability (35%), anxiety (24%) and apathy (19%). In some cases, agitation (4%), abnormal motor behavior (3%) and delusions (1%) were detected. Hallucination, disinhibition and euphoria or elation were not detected in this series. CONCLUSION: Data show a certain similarity with occidental culture environment, globally considered. The presence of behavioral and psychological disorders in patients with MCI could be a marker for later development of dementia. NPI can be a usable tool when detection and evaluation of these symptoms is required.
