Cultural adaptation and validation of a peninsular Spanish version of the MSTCQ© (Multiple Sclerosis Treatment Concerns Questionnaire). / Adaptación cultural y validación al español de España del MSTCQ© (Multiple Sclerosis Treatment Concerns Questionnaire).

INTRODUCTION: Although subcutaneous treatments for multiple sclerosis (MS) have been shown to be effective, adverse reactions and pain may adversely affect treatment satisfaction and adherence. This study presents an adapted and validated Spanish version of the Multiple Sclerosis Treatment Concerns Questionnaire© (MSTCQ), which evaluates satisfaction with the injection device (ID) across 4 domains: injection system (A), side effects (B) (flu-like symptoms, reactions, and satisfaction), experience with treatment (C) and benefits (D). METHODS: Two study phases: 1) Cultural adaptation process with input from experts (n=6) and patients (n=30). 2) Validation obtained by means of an observational, cross-sectional, multi-centre study evaluating 143 adult MS patients using an ID. Tools employed: MSTCQ©, Patient-Reported Indices for Multiple Sclerosis (PRIMUS©), and Treatment Satisfaction Questionnaire for Medication (TSQM©). Psychometric properties: Feasibility (percentage of valid cases and floor/ceiling effects); Reliability (Cronbach α) and test-retest correlation (n=41, intraclass correlation coefficient, ICC); and construct validity (factor analysis of domains A and B) and convergent validity (Spearman rank-order correlation for MSTCQ© vs TSQM©). RESULTS: Mean age (SD) was 41.94 (10.47) years, 63% of the group were women, and 88.11% presented relapsing-remitting MS. Mean (SD) EDSS score was 2.68 (1.82) points. MSTCQ© completion was high (0%-2.80% missing data). Internal consistency was high at α=0.89 for the total score (A+B) and α=0.76, 0.89, and 0.92 for domains A, B, and C, respectively. The version demonstrated excellent test-retest reliability for the total (ICC=0.98) and for domains A, B, and C: ICC=0.82, 0.97, and 0.89, respectively. Factor analysis corroborated the internal structure of the original questionnaire. The association between total and domain scores on both the MSTCQ© and the TSQM© was moderately strong (Rho=0.42-0.74) and significant (P<.05 and P<.01). CONCLUSION: The Spanish version of MSTCQ© demonstrates appropriate psychometric properties.

Eyelid myokymia in patients with migraine taking topiramate.

OBJECTIVE: Although ocular side effects of topiramate are common, neuroophthalmologic manifestations such as blepharospasm, myokymia and oculogyric crisis are scarcely reported. METHODS: We present a serie of 8 patients with migraine who developed eyelid myokymia after treatment with topiramate. We reviewed all patients with migraine treated with topiramate attending the headache outpatient clinic of our hospital from January 2008 to December 2012. RESULTS: During the study period, a total of 140 patients with migraine were treated with topiramate in our headache clinic. Eight presented eyelid myokymia after beginning treatment with topiramate (5,7%). Topiramate was stopped and myokymia disappeared in all patients, it was prescribed again and eyelid myokymia reappeared with their previous characteristics in all patients. CONCLUSIONS: Eyelid myokymia is an underreported side-effect of topiramate in patients with migraine, of unknown cause, so that in future, further studies are need to examine whether patients with migraine are predisposed or not to this adverse effect.

Migraine education brochures and patient-perceived satisfaction.

INTRODUCTION: Brochures are commonly used as educational tools in daily neurological practice. They are provided to increase the general population's knowledge of a specific disease and also to combat sources of erroneous information. Surveys are the most commonly used method of ascertaining user satisfaction with services received. OBJECTIVES: This study will assess patient-perceived satisfaction and provide feedback to measure the comprehensibility and overall utility of an educational brochure on migraine. MATERIAL AND METHODS: Open prospective multicentre study of a group of patients diagnosed with migraine in neurology clinics in Alicante province. During the initial visit, each patient received a migraine brochure prepared by the Valencian Society of Neurology's study group for headaches (CEFALIC). During a follow-up visit, they were then asked to fill out a personal survey on the overall quality of the information in the brochure. RESULTS: We included a total of 257 patients diagnosed with migraine (83% episodic migraine; 17% chronic migraine); mean age was 37.6 years. Two hundred seven patients confirmed having read the brochure (80.5%); 50 patients (19.5%) either forgot to read it or had no interest in doing so. The brochure seemed interesting and easy to understand according to 90% of the patients. Seventy-six per cent of the respondents stated that reading the brochure increased their overall knowledge of migraine, while 50% of the patients found the brochure useful for improving migraine control. CONCLUSIONS: Patients found the migraine educational brochure to be comprehensible, a means of increasing overall knowledge of the disease, and useful for increasing control over migraines. Evaluations of the educational brochures that we provide to our patients with migraine should be studied to discover the causes of dissatisfaction, determine the level of quality of service, and investigate potential areas for improvement.

Clinical characteristics associated with psychosocial functioning among patients with uncomplicated epilepsy in Spain.

OBJECTIVE: To identify the clinical characteristics associated with poor psychosocial functioning among Spanish patients with epilepsy but no other neurological or psychiatric disorder. METHODS: Between May and September 2001 a survey among patients with epilepsy was carried out in 32 Spanish health care centres. The selection criteria of patients were attendance to a routine neurologist visit, to be aged between 25 and 64 and not having another additional neurological handicap (n=812). Psychosocial function was elicited through six indicators: educational level, marital status, unemployment status, restricted car driving, self-perception of epilepsy as an important limiting factor in the educational level achieved and, among unemployed, as the cause of their unemployment. Multiple logistic regression models were fitted in order to calculate adjusted odds ratios (aOR) and their 95% confidence intervals. RESULTS: After simultaneously adjusting for socio-demographic variables and clinical characteristics, the six outcomes analysed increased with seizure frequency. Moreover, all the outcomes except low educational level were also related to early age at onset of epilepsy. Although no relation with objective educational level was found, there was a strong association between early age at onset of symptoms and self-perception of epilepsy as an important limiting factor of educational achievement. CONCLUSION: These findings emphasize the need for more effective treatment of epilepsy and also highlight the importance of a psychosocial approach to management of epilepsy for patients with an early onset of symptoms in order to prevent social limitations in adult life.

[Nontraumatic cerebral hematoma in young adults: a study of 42 cases]. / Hematoma intracerebral no traumático en adultos jóvenes: estudio de 42 casos.

BACKGROUND: Cerebrovascular disease has particular features in young adults (15-45 years). In this context, non-traumatic intracranial hematoma (NTICH) has received little attention. Therefore, its analysis has been attempted focusing on etiology, localization and short term prognosis. METHODS: 42 patients aged 15-45 years who were admitted because of NTICH were evaluated. 41 variables were analyzed with chi-square method and Fischer's exact test. RESULTS: The localization of hematoma was as follows: basal ganglia/thalamus in 59%, lobar in 19%, posterior fossa in 12%, pure intraventricular in 2 cases and multiple in one case. The most common etiology was hypertension (HT) (32%), followed by arteriovenous malformations (12%), oral anticoagulants (10%), chronic alcohol abuse (10%), coagulation disorders and one central nervous system arteriopathy; 12 cases were idiopathic. On the basis of etiology two groups were distinguished: 15-30 years (no case with hypertension) and 30-45 years (HT as the leading cause). Survival was 89%. CONCLUSIONS: NTICH in young adults has a heterogeneous etiology. On the basis of the most common cause two groups can be considered: from 15 to 30 years (arteriovenous malformation) and from 30 to 45 years (HT). High blood pressure at the time of stroke is correlated with previous HT. The short term life prognosis is better than that of NTICH in general series. Deterioration of consciousness in the acute phase and oral anticoagulation are poor prognostic factors.

[Cerebrovascular morbidity in Spain: incidence and prevalence]. / Morbilidad por enfermedad cerebrovascular en España: incidencia y prevalencia.

OBJECTIVE: A descriptive study of the morbidity due to cerebrovascular disease in Spain. METHODS: A review of the studies of the incidence and prevalence of cerebrovascular disease in Spain. A search of the literature available through the database MEDLINE. RESULTS: The annual incidence of stroke in Spain is approximately 150 per 100,000 inhabitants. The annual incidence of transient ischaemic accidents is 35-60 per 100,000 in community studies and nearly 300 per 100,000 in door-to-door studies. In the population aged over 65 years, the prevalence of stroke is 4%-8% and the prevalence of transient ischaemic accidents is 2%-3%. CONCLUSION: The incidence and prevalence figures for cerebrovascular disease in Spain are high.

[First adult seizures]. / Primera crisis en el adulto.

This review analyses the diagnostic, prognostic and therapeutic aspects of a first epileptic crisis occurring in adult patients. Although it is generally accepted that a cranial CT scan is indicated after the first crisis in order to rule out a structural cerebral lesion after the first crisis, the need for cerebral MR studies in such cases is debatable. The decision to begin anticonvulsant treatment is very controversial, mainly because of the difficulty in assessing the risk of recurrence in any given person. In each case this decision should be reached after bearing in mind the factors indicating risk of recurrence, the patient's personal condition, their work and their own opinion.

[Prevention of migraine: a pharmacoepidemiological study]. / Prevención de la migraña: un estudio farmacoepidemiológico.

INTRODUCTION: This study aims to perform a descriptive analysis of the usage patterns of migraine prophylactic medications by various neurologists in our setting. MATERIAL AND METHODS: The first preventive treatment prescribed for migraine in patients not associated to other diagnoses of primary headache was recorded in three outpatient neurology clinics and one headache specific clinic. RESULTS: A total of 235 prophylactic treatments out of 669 patients were initiated. The patients were aged 37 +/- 12 years (mean +/- standard deviation) and 84.45% were women. Migraines with aura accounted for 18.9% of migraines. By order of frequency, the prophylactic treatments administered were topiramate (43%), beta-blockers (18%), flunaricine (17%), amitriptyline (14%), selective serotonin reputake inhibitors (6%) and others (2%). Beta-blockers and flunaricine were used much more frequently in men (29.7% and 27% versus 15.9% and 14.4%, respectively) and antidepressants were used more in women (21.87% versus 5.4%). The most frequently used antidepressant was amitriptyline, and its use increases with the age of the patient, it being the most frequently used treatment in over 60-year-old patient group. CONCLUSIONS: At present, topiramate has become the first preventive treatment option for migraine in our setting, especially in young women. There is greater variability in the choice of an alternative treatment. Amitriptyline is the first choice within the antidepressants and is almost exclusively prescribed in women with migraine and elderly age.

[Classic antiepileptic and new generation antiepileptic drugs: gender differences in effectiveness and adverse drug reactions]. / Fármacos antiepilépticos clásicos y de nueva generación: diferencias de sexo en la efectividad y en las reacciones adversas.

INTRODUCTION: Women are more likely to suffer adverse drug reactions. Moreover adverse drug reactions differ depending on gender. The main objective of new generation antiepileptic drugs (AED) is to reduce adverse drug reactions while maintaining the same effectiveness as the classic ones. OBJECTIVES: a) To identify sociodemographic and clinical variables associated with being treated with new generation AEDs, and b) to compare effectiveness, averse drug reactions and quality of life among patients treated with monotherapy, either with classic or with new generation AEDs, examining the potential gender differences. PATIENTS AND METHODS: A survey among 990 patients aged 16-64 with epilepsy was carried out in 32 Spanish hospitals (response rate: 96 %). For the purposes of this study patients treated with monotherapy (n = 496) were selected. The outcome variables were: effectiveness in seizure control, adverse drug reactions and three dimensions of the SF-36 questionnaire (vitality, mental health and self-perceived health status). RESULTS: 21 % of women and 8% of men were treated with new AEDs. Women were more likely to be treated with new generation AEDs. Moreover, age of epilepsy onset was also positively related to new AEDs and a gradient was found. Whereas no differences in effectiveness, adverse drug reactions or quality of life were observed among men, among women, those treated with new generation AEDs had less adverse drug reactions but, on the other hand, effectiveness for controlling seizures was lower. CONCLUSIONS: Women are more likely to be treated with new AEDs. Although these new treatments seem to have less adverse drug reactions among females, their effectiveness in controlling seizures are lower than that of classic AEDs.

[Quality of the health care to the epileptic patients in Spain]. / Calidad asistencial en epilepsia. Situación de la asistencia a los pacientes epilépticos en España.

INTRODUCTION: The objective of the study was to evaluate the quality of the health care to the epileptic patient in Spain including recently diagnosed patients, controlled patients and medically refractory patients. METHODS: Throughout years 2001-2002 a questionnaire of consensus was agreed by neurologists from surgical epilepsy units, epilepsy units, community hospitals and outpatient clinics. RESULTS: A total of 139 questionnaires were analysed. Only one third of the hospitals had a specialized epilepsy clinic. The longest waiting lists for diagnostic procedures were video EEG and Holter EEG, with 175 and 97.6 days, respectively. Clear differences between autonomous communities as far as availability of neurologists on duty, availability of diagnostic tests and number of epilepsy units are stated, existing, in general, more resources in the autonomous communities with health transferred before 2002 and Madrid. CONCLUSIONS: As much the lack of resources as the inequalities indicate that we are still far from the quality standards recommended by the International League Against Epilepsy (ILAE), lacking a suitable lanning that eliminates the inequalities and it so approaches us a system of assistance integrated in different levels as it is set out by the international scientific community.

Acute headache of recent onset and subarachnoid hemorrhage: a prospective study.

Twenty-seven patients with acute severe headache of recent onset were prospectively recruited in the Emergency Room. Mean duration of headache was 61 hours. CT scan disclosed subarachnoid bleeding in 4 patients and spinal tap revealed subarachnoid hemorrhage (SAH) in 5 patients with normal CT scan. In most SAH cases pain was bilateral, very intense and involving the occipital region. Four of these patients had doubtful or no nuchal rigidity and in one, pain improved while in the Emergency Room. In every case with an intense acute severe headache of recent onset CT scan and (if normal) a lumbar puncture are warranted to help rule out a SAH.

[Practical exercises on diagnostic test interpretation]. / Ejemplos prácticos de interpretación de pruebas diagnósticas.

Although medical literature places great emphasis on therapy, diagnosis remains an essential part of medical practice. We present four clinical cases that show the interaction between pre-test probabilities and the accuracy of investigations (sensitivity, specificity, predictive values and likelihood ratios) The first example studies the influence of meningeal signs in the diagnosis of meningitis. The second one analyzes the diagnostic utility of investigations in patients suspected of dementia. The third example examines the change in the probability of carpal tunnel syndrome depending on the physical examination and the electrodiagnostic studies. The last example explains the use of ROC curves in the diagnosis of demyelinating disease with CSF-IgG index.

Peripheral iron metabolism in patients with focal cerebral ischemia.

To ascertain the possible role of iron as a risk factor for cerebral ischemia, we studied the serum levels of iron, transferrin and ferritin in 42 patients between the third and seventh days after a cerebral ischemic event (transient ischemic attack, reversible ischemic neurological deficit or cerebral infarction) and in 62 matched controls. The serum levels of iron did not differ significantly between cerebral ischemic patient and control groups. Serum transferrin levels were lower and ferritin higher in stroke patients than in controls. These values were not influenced by age, blood pressure, or smoking and alcohol drinking habits. These results suggest that iron stores could be related to the risk for cerebral ischemia.

Serum levels of nitrates in focal cerebral ischemia.

To ascertain the possible role of nitric oxide (NO) as risk factor for cerebral ischemia, we studied the serum levels of nitrate (oxidation product that provides an indirect estimation of NO), in 49 patients between the 3rd and 7th days after a cerebral ischemic event (TIAs, RIND and cerebral infarction) and in 65 matched controls. The serum levels of nitrate did not differ significantly between cerebral ischemic patient and control groups (42.6 ± 334 and 44.8 ± 2.67 ± µmol/l, respectively). They were not influenced by age, blood pressure, or smoking and alcohol-drinking habits. These results suggest that serum levels of nitrate are apparently unrelated to the risk for cerebral ischemia.
