[Clinical characteristics of vestibular migraine: considerations in a series of 41 patients]. / Caracteristicas clinicas de la migraña vestibular: consideraciones en una serie de 41 pacientes.

INTRODUCTION: After years of debate about its being approached from headaches and its denomination, vestibular migraine has recently been included in the research appendix of the 3rd edition of the International Headache Classification. AIM: To analyse the characteristics of a series of patients with vestibular migraine who visited because of headaches. PATIENTS AND METHODS: Our sample consisted of patients who were attended in a headache unit between January 2014 and December 2015. The demographic variables and the characteristics of both migraine and vestibular symptoms were considered, and cases with other otorhinolaryngological conditions were excluded. RESULTS: The sample was finally made up of 41 patients (11 males, 30 females) with a mean age of 31.8 ± 13.3 years at the time they were included in the study. Sixteen patients (39%) met criteria for chronic migraine and two (4.9%) presented visual auras. The vestibular symptoms were considered severe in eight cases (19.5%) and occurred in 74.6% of the migraine attacks. Vertigo was described as internal in 18 cases (43.9%), external in 22 (53.7%) and mixed in one case (2.4%). The most frequent symptom was positional vertigo (n = 25; 61%), followed by that induced by head movements (n = 18; 43.9%) and spontaneous (n = 15; 36.6%). Accompanying symptoms included tinnitus (n = 12; 29.3%) and a feeling of fullness in the ear (n = 8; 19.5%). CONCLUSION: It is not uncommon to identify symptoms consistent with vestibular migraine in patients who visit a headache unit; they are patients whose day-to-day activities are not usually affected by their vertigo.

TITLE: Caracteristicas clinicas de la migraña vestibular: consideraciones en una serie de 41 pacientes.Introduccion. Tras años de debates sobre su enfoque desde las cefaleas y su denominacion, la migraña vestibular ha sido recientemente incluida en el apendice de investigacion de la III edicion de la Clasificacion Internacional de Cefaleas. Objetivo. Analizar las caracteristicas de una serie de pacientes con migraña vestibular en los que el motivo de consulta fue la cefalea. Pacientes y metodos. Pacientes atendidos en una unidad de cefaleas entre enero de 2014 y diciembre de 2015. Se consideran las variables demograficas y caracteristicas tanto de la migraña como de los sintomas vestibulares, y se excluyen los casos con otras patologias otorrinolaringologicas. Resultados. Se incluyen 41 pacientes (11 varones, 30 mujeres) con una edad media de 31,8 ± 13,3 años en el momento de la inclusion. Dieciseis pacientes (39%) reunian criterios de migraña cronica y dos (4,9%) presentaban auras visuales. Los sintomas vestibulares fueron considerados graves en ocho casos (19,5%) y ocurrian en un 74,6% de los episodios de migraña. El vertigo se describia como interno en 18 casos (43,9%), externo en 22 (53,7%) y mixto en uno (2,4%). El sintoma mas frecuente fue el vertigo posicional (n = 25; 61%), seguido del inducido por movimientos cefalicos (n = 18; 43,9%) y el espontaneo (n = 15; 36,6%). Como sintomas acompañantes se observaron acufenos (n = 12; 29,3%) y pletora aural (n = 8; 19,5%). Conclusion. La identificacion de sintomas compatibles con una migraña vestibular no es excepcional en los pacientes que acuden a una unidad de cefaleas; se trata de pacientes en los que el vertigo no suele interferir en sus actividades habituales.

Burning mouth syndrome: Clinical description, pathophysiological approach, and a new therapeutic option. / Síndrome de boca ardiente: descripción clínica, planteamiento fisiopatológico y una nueva opción terapéutica.

INTRODUCTION: Burning mouth syndrome is defined as scorching sensation in the mouth in the absence of any local lesions or systemic disease that would explain that complaint. The condition responds poorly to commonly used treatments and it may become very disabling. METHODS: We prospectively analysed the clinical and demographic characteristics and response to treatment in 6 cases of burning mouth syndrome, diagnosed at 2 tertiary hospital headache units. RESULTS: Six female patients between the ages of 34 and 82 years reported symptoms compatible with burning mouth syndrome. In 5 of them, burning worsened at the end of the day; 4 reported symptom relief with tongue movements. Neurological examinations and laboratory findings were normal in all patients and their dental examinations revealed no buccal lesions. Each patient had previously received conventional treatments without amelioration. Pramipexol was initiated in doses between 0.36mg and 1.05mg per day, resulting in clear improvement of symptoms in all cases, a situation which continues after a 4-year follow up period. CONCLUSIONS: Burning mouth syndrome is a condition of unknown aetiology that shares certain clinical patterns and treatment responses with restless leg syndrome. Dopamine agonists should be regarded as first line treatment for this entity.

Impulsivity among migraine patients: Study in a series of 155 cases. / Impulsividad en pacientes migrañosos: estudio en una serie de 155 casos.

INTRODUCTION: Impulsivity is a psychological phenomenon that has not been extensively studied in headache patients. We aim to assess the presence of impulsivity in patients with chronic migraine (CM) and medication overuse (MO). PATIENTS: All patients examined in an outpatient headache clinic between January 2013 and March 2014 were included. Episodic migraine, CM, and MO were diagnosed according to ICHD-III beta criteria. We prospectively gathered demographic and clinical characteristics. Mood disorders were evaluated using the Hospital Anxiety and Depression Scale (HADS) and impulsiveness was assessed with the Plutchik impulsivity scale. RESULTS: A total of 155 patients were included (22 men, 133 women). The mean age (SD) was 38.2 (11.7) years (range, 18-70); 104 patients (67.1%) presented CM and, among them, 74 (71.1%) had MO. Of the patient total, 28.4% met criteria for anxiety, 7.1% for depression and 16.1% for impulsivity. The CM group showed higher scores for HADS-anxiety (8.5 [SD 4.5] vs. 6.4 [SD 3.6], p=0.003) and HADS-depression (4.4 [4.3] vs. 1.9 [2.3], p<0.001). Among CM cases only, scores for HADS-anxiety (9.3 [4.4] vs. 6.8 [4.3], p=0.01) and HADS-Depression (5.1 [4.6] vs. 2.7 [2.9], p=0.002) were higher in patients who also had MO. We found no associations between Plutchik scale scores or presence of impulsivity with either CM or MO. CONCLUSION: Impulsivity is a common trait in our population of migraine patients, but unlike mood disorders, it is not correlated with either CM or MO.

HaNDL syndrome: Correlation between focal deficits topography and EEG or SPECT abnormalities in a series of 5 new cases. / Síndrome HaNDL: correlación entre la topografía del déficit neurológico y las alteraciones en electroencefalograma y SPECT en una serie de 5 nuevos casos.

INTRODUCTION: Transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) is characterised by migraine-like headache episodes accompanied by neurological deficits consisting of motor, sensory, or aphasic symptoms. Electroencephalogram (EEG) and single photon emission computed tomography (SPECT) may show focal abnormalities that correspond to the neurological deficits. We aim to evaluate the correlation between focal deficit topography and EEG or SPECT abnormalities in 5 new cases. PATIENTS: We retrospectively reviewed patients attended in a tertiary hospital (January 2010-May 2014) and identified 5 patients (3 men, 2 women) with a mean age of 30.6 ± 7.7 (21-39) years. They presented 3.4 ± 2.6 episodes of headache (range, 2-8) of moderate to severe intensity and transient neurological deficits over a maximum of 5 weeks. Pleocytosis was detected in CSF in all cases (70 to 312 cells/mm3, 96.5-100% lymphocytes) with negative results from aetiological studies. RESULTS: At least one EEG was performed in 4 patients and SPECT in 3 patients. Patient 1: 8 episodes; 4 left hemisphere, 3 right hemisphere, and 1 brainstem; 2 EEGs showing left temporal and bilateral temporal slowing; normal SPECT. Patient 2: 2 episodes, left hemisphere and right hemisphere; SPECT showed decreased left temporal blood flow. Patient 3: 3 left hemisphere deficits; EEG with bilateral frontal and temporal slowing. Patient 4: 2 episodes with right parieto-occipital topography and right frontal slowing in EEG. Patient 5: 2 episodes, right hemisphere and left hemisphere, EEG with right temporal slowing; normal SPECT. CONCLUSION: The neurological deficits accompanying headache in HaNDL demonstrate marked clinical heterogeneity. SPECT abnormalities and most of all EEG abnormalities were not uncommon in our series and they did not always correlate to the topography of focal déficits.

Characteristics of the first 2,000 patients registered in a specialist headache clinic.

OBJECTIVES: Headache is a common cause of medical consultations. We aim to analyze demographic characteristics of first two thousand patients in our register, and the incidence of their different headaches coded according to the International Classification of Headache Disorders, ii edition (ICHD-II). PATIENTS AND METHODS: On January 2008 a headache outpatient clinic was established in a tertiary hospital. Patients could be referred by general practitioners according to previously consensused criteria, as well as by general neurology or other specialities clinics. The following variables were prospectively collected on all patients; age, sex, referral source, complementary tests required, and the previously prescribed symptomatic or prophylactic therapies. All headaches were classified accordingly to ICHD-II. When a patient fulfilled criteria for more than one type of headache, all of them were diagnosed and classified. RESULTS: In October 2012, 2000 patients (ratio women/men 2.59/1) had been seen in our headache clinic. The median age was 42 years (range: 11-94), 55.3% were referred from primary care, and 68.1% did not require complementary tests. A total of 3095 headaches were recorded in these 2000 patients, of which 2222 (71.8%) were considered primary headaches, 382 (12.3%) secondary headaches, with 117 (3.8%) corresponding to cranial neuralgias, 136 (4.3%) were unclassified headaches, and 238 (7.7%) were included in the research Appendix of the ICHD-II. The most represented group was 1 (migraine) with 53% of all headaches. CONCLUSIONS: The characteristics of first 2000 patients in our register were comparable to those previously described in other types of headache outpatient clinics. Migraine was the most frequent diagnosis, and secondary headaches were not as frequent in our series. Most headaches could be coded according to ICHD-II criteria.

Chronic migraine with and without medication overuse: experience in a hospital series of 434 patients.

INTRODUCTION: Chronic migraine (CM) is a complication of episodic migraine, favored by risk factors as medication overuse (MO). We intend to compare demographic and clinic characteristics of a series of CM patients, with and without MO. METHODS: The study included patients with CM (2006 revised criteria) attended in a headache outpatient office located in a tertiary hospital between January 2008 and May 2012. We recorded demographic characteristics, age at migraine onset, time from onset, previous use of symptomatic or preventive therapy, and headache impact measured with six-item headache impact test (HIT-6). RESULTS: A total of 434 patients (357 women, 77 men) were diagnosed with CM out of the 1868 (23.2%) that attended our clinic. Of these, 258 (72.2%) fulfilled criteria of MO, and 59.8% of those with MO, and 41.1% of cases without MO had previously received preventative treatment (P<.001). Age at onset of migraine was lower in MO patients (21.2±10.1 vs 23.8±12.5 years, P=.02) and time from onset to headache clinic consultation was higher in MO cases (23.8±14.1 vs 18.3±14.8 years, P<.001). We found no difference between both groups in average HIT-6 score and the percentage of patients with a HIT-6 score over 55. CONCLUSIONS: CM, with or without MO, is a burdensome group of patients in our headache clinic. Patients with MO are referred later and have more frequently received preventive treatments.

Headache in the elderly: characteristics in a series of 262 patients.

INTRODUCTION: Although headache prevalence decreases in patients older than 65, headaches are a common complaint and their different clinical and therapeutic features must be understood. This article analyses the clinical characteristics of elderly patients treated in an outpatient headache unit. METHODS: We collected demographic and clinical data from patients treated in a tertiary hospital headache unit between January 2008 and May 2013. Headaches were codified according to the International Classification of Headache Disorders, 2nd edition (ICHD-2). RESULTS: Of a total of 1868 patients treated, 262 patients (14%, 189 women and 73 men) were older than 65 years. Ninety-nine (68 women, 31 men, 5.3% of the total) were over 75. Headaches began after the age of 65 in only 136 patients (51.9%). The 362 headaches were codified as follows: 23.8% as Group 1 (Migraine) and 28.7% as Group 2 (Tension-type headache). We diagnosed 58 (16%) secondary headaches; 26 (7.2%) were classified as Group 13 (Cranial neuralgias) and 23 (6.4%) in Group 14 (Other headaches). Symptomatic medication overuse was detected in 38 patients (14.5%). We also identified headaches considered typical in the elderly, including chronic migraine (41 cases), hypnic headache (6), occipital neuralgia (4), SUNCT (2), cervicogenic headache (1), primary cough headache (1), and giant cell arteritis (2). CONCLUSIONS: Elderly patients were frequently treated in our outpatient headache unit. Tension-type headache was the most common diagnosis in this population. Geriatric headache syndromes such as hypnic headache or occipital neuralgia were also represented in our series.
