Strength of association of classical vascular risk factors in young patients with ischaemic stroke: a case-control study.

INTRODUCTION: Recent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established. METHODS: We compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup. RESULTS: Using logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology. CONCLUSIONS: Hypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.

Longitudinal study of in-hospital consultations with neurology in a tertiary hospital. A health care activity on the increase.

OBJECTIVE: In-hospital consultation (IHC) is a service that some medical specialties provide to others with the aim of resolving complications in patients admitted to different hospital units. The aim of this study is to perform a descriptive analysis and longitudinal study of IHCs received in our department during the last 5 years. METHOD: A retrospective study was conducted on the IHCs made within the period 2005-2009. The data analysed were as follows: department of origin of the IHC, reason for consult, date, priority of care, definitive diagnosis, need for follow-up, need for transfer, and the demographic data of the patients. RESULTS: There were a total of 1458 IHCs in the period studied. The mean age of the patients was 58.2 ± 19.10 years, and 837 (57.6%) were males. The number of IHCs per year was: 2005: 263; 2006: 226; 2007: 239; 2007: 239, 2008: 329 and 2009: 401. The majority (86.8%) had normal priority, 8.5% high priority, and 4.7% were urgent. The Emergency Department (12%), Cardiology (10.9%), General Medicine (9.8%) and Psychiatry (8.9%) were the services with the highest demand. The most frequent reasons for consulting were loss of consciousness and epileptic seizures (24.6%), cerebral vascular disease (21.1%), and confusional states and cognitive impairment (13.4%). Over one third (36.8%) were resolved in the first consultation, and the remainder (63.8%) required follow up. Of all the cases assessed, 8.4% required transfer to Neurology. CONCLUSIONS: IHC is a complex activity that may not resolve all questions in a single visit. It involves a health care burden which is increasing annually. The increasing diagnostic complexity of the neurology, as well as the increasingly more specific treatments are the factors that lead to this higher demand.

[Isolated mesencephalic stroke related to a ruptured intracranial dermoid cyst]. / Ictus isquémico mesencefálico aislado secundario a ruptura de quiste dermoide.

Dermoids cysts are embrionary benign lesions that comprise approximately 0.04-0.25% of all intracranial tumors. Occasionally they break and spread their content into subarachnoid space and/or lateral ventricles causing several acute or delayed symptoms. Debut of this type of tumor as acute stroke is poorly reflected in literature. We present a 26-year-old woman with a isolated mesencephalic infarct secondary to spontaneous rupture of a dermoid cyst. We discuss the possible pathophysiological mechanisms for this condition and review the literature.

Los quistes dermoides son lesiones benignas deorigen embrionario que representan del 0.04 a 0,25%de todos los tumores intracraneales. Estos quistesocasionalmente pueden romperse diseminándose elcontenido graso intraquístico al espacio subaracnoideoy/o los ventrículos laterales. En este caso puede provocardiversas manifestaciones clínicas de forma agudao retardada. El debut de este tipo de tumor con unictus agudo está escasamente reflejado en la literatura.Presentamos el caso de una mujer de 26 años con uninfarto mesencefálico aislado secundario a la rupturade un quiste dermoide.
