Although migraine (MH) and tension type headache (TTH) are the most common and important causes of recurrent headache in adolescents, they are poorly understood and not recognized by parents and teachers, delaying the first physician evaluation for correct diagnosis and management. The purpose of this study is to assess the knowledge about headache impact among the students of a Communication Private High School in Rimini city, and to evaluate the main different types of headaches interfering with school and social day activities. ⋯ Out of the 60 students, 84 % experienced recurrent headache during the last 12 months. 79 % were females, aged 17-20 years; a family history was present in 74 % of headache students, in the maternal line; 45 % of subjects were identified as having MH and 27 % TTH; 25 % had morning headache and 20 % in the afternoon; fatigue, emotional stress and lack of sleep were the main trigger factors for headache, respectively in 86, 50 and 50 % of students; 92 % of headache students could not follow the lessons, could not participate in exercises and physical activity because of the headache; none had consulted a medical doctor and the 90 % of all students had never read, listened or watched television about headache. This study remarks on the need to promote headache educational programs, starting from high school, to increase communication between teachers-family-physician and patient-adolescents, with the goal to have an early appropriate therapeutic intervention, improvement of the quality of life and to prevent long-term headache disease in the adult age.

The aim of this study was to investigate the clinical characteristics and patterns of diagnosis and treatment of patients with tension-type headache in the neurology outpatient clinic of a university hospital in China. This cross-sectional study was conducted in the neurological clinic of a tertiary care hospital in Chongqing between March 2010 and May 2010. All consecutive patients with the chief complaint of headache were asked to complete a face-to-face interview with physicians. ⋯ In conclusion, many tension-type headache patients did not receive a physician diagnosis of tension-type headache or effective treatment in the neurological clinic. Tension-type headache remains underrecognized in China. Better education among physicians is needed so as to improve the diagnosis and treatment of tension-type headache.

To date, no studies are available on the effect of pregabalin in dystonia. A patient with subarachnoidal and cerebral hemorrhage was treated with pregabalin for neuropathic pain. ⋯ One possible explanation for these symptoms could be neuronal hyperactivity within still-functioning pathways in connection with the motor cortex. Preponderance of activity in potentially compensatory structures could be suppressed by pregabalin: therefore, its potential benefit in subacute secondary dystonia in cases with orbital brain involvement is suggested.

This study aimed to investigate the role of p38 MAPK phosphorylation and opening of the mitoK(ATP) channels in the sevoflurane-induced delayed neuroprotection in the rat brain. Adult male Sprague-Dawley rats (250-300 g) were randomly assigned into four groups: ischemia/reperfusion (Control), sevoflurane (Sevo), 5-hydroxydecanoate (5-HD) + sevoflurane (5-HD + Sevo) and 5-HD groups and were subjected to right middle cerebral artery occlusion (MCAO) for 2 h. Sevoflurane preconditioning was induced 24 h before MCAO in sevoflurane and 5-HD + sevoflurane groups by exposing the animals to 2.4% sevoflurane in oxygen for 60 min. ⋯ Sevoflurane treatment also caused increased phosphorylation of p38 MAPK at 24 and 72 h after reperfusion. These beneficial effects were attenuated by 5-HD. Blockade of cerebral protection with 5-HD concomitant with decrease in p38 phosphorylation suggests that mitoK(ATP) channels opening and p38 phosphorylation participate signal transduction cascade of sevoflurane preconditioning and p38 MAPK activation may be a downstream of opening mitoK(ATP) channels.

Moderate to severe migraine attacks are treated with triptans. However, about 25% of migraineurs fail to respond to triptans. We investigated the involvement of gene polymorphisms, personality traits and characteristics of headache, and made a scoring system for prediction of clinical response to triptans in patients with migraine. ⋯ The score in inconsistent responders (1.6 ± 0.6) was significantly higher than that in consistent responders (0.8 ± 0.7, P < 0.001). Sensibility of low-score (RI = 0) group was 100%, and specificity of high-score (PI ≥ 2) group was 87%. The proposed scoring system should in the future be the object of larger studies to confirm its validity.
