Recurrent Headaches (recurrent + headaches)
Selected AbstractsCommon CX3CR1 Alleles Are Associated With a Reduced Risk of HeadachesHEADACHE, Issue 7 2008Christophe Combadière PhD Objectives., The aim of this study was to investigate the role of the chemokine receptor CX3CR1 in headaches and migraine. Methods., Distribution of 2 polymorphisms of the chemokine receptor CX3CR1 (V249I and T280M) was determined in a population-based sample of 1179 elderly individuals. Results., Heterozygotes for both CX3CR1 polymorphisms had a reduced risk of recurrent headaches, with an odds ratio (OR) of 0.64 (95% confidence interval [CI] = 0.46-0.90) for the I249 allele and 0.55 (95% CI = 0.38-0.81) for the M280 allele. Haplotype analysis showed that carriers of the rarer CX3CR1 I249-M280 haplotype had a reduced risk of recurrent headaches, with an OR of 0.57 (95% CI = 0.41-0.80, P = .001). This association was seen for both nonmigraine headaches (OR = 0.47, 95% CI = 0.28-0.79, P = .004) and migraine (OR = 0.65, 95% CI = 0.43-0.98, P = .041). Conclusions., These results need to be replicated but suggest that the chemokine receptor CX3CR1 may play a role in recurrent headaches. [source] Epidemiology and Symptomatology of Migraine Among School Children: Denizli Urban Area in TurkeyHEADACHE, Issue 8 2004Mehmet Zencir MD Objective.,This study was aimed at finding the prevalence, associated factors, and symptomatology of migraine among 5 to 8 grades of secondary and 9 to 11 grades of high school children (age range between 11 and 18 years old) in the Denizli urban area in the western part of Turkey. Background.,Data from the developed countries indicate that migraine is the most common cause of recurrent headaches in children. Also, childhood migraine is sufficiently severe to prevent the half of the suffering children from carrying on their usual daily activities. Methods.,A cross-sectional school-based study was conducted between May 2000 and June 2000. There were 2,490 participants selected by a multistage stratified clustered sampling procedure. A validated self-administered questionnaire designed according to the International Headache Society criteria was given to the school children of age between 11 and 18 years. Results.,Overall migraine prevalence was 8.8%; it was 6.7% in boys and 11.0% in girls (OR: 1.7; 95% CI: 1.3 to 2.3). Among girls, the highest prevalence (17.7%) occurred at 15 years of age, but among boys, the highest prevalence (11.9%) occurred at 16 years of age. Of children with migraine, 56.5% had a positive family history, and only 29.1% visited a doctor for headache. Conclusion.,Migraine is a common health problem among school children in Denizli urban area and it often goes underdiagnosed. [source] Lifetime Prevalence and Characteristics of Recurrent Primary Headaches in a Population-Based Sample of Swedish TwinsHEADACHE, Issue 8 2002Dan A. Svensson MSc Objective.,To examine the lifetime prevalence and other characteristics of recurrent primary headaches in twins. Background.,The twin model may provide insights into the role of genetic and environmental influences in headache disorders. However, assumptions as to whether twins are representative of the general population, and whether monozygotic and dizygotic twins are similar have rarely been addressed. Methods.,The study population consisted of a random sample of 17- to 82-year-old twins from the Swedish Twin Registry (n = 1329). Structured interviews on the telephone by lay personnel and the International Headache Society criteria were used for assessment and diagnosis of recurrent primary headaches. Prevalence data of the general population for migraine and tension-type headache was obtained from various published reports. Results.,A total of 372 subjects (29%) had ever had recurrent headaches. In total, 241 recurrent headache sufferers fulfilled the criteria for migraine or tension-type headache, and the lifetime prevalence was 7.1% for migraine without aura, 1.4% for migraine always with aura, 1.9% for migraine occasionally with aura, 9.4% for episodic tension-type headache, and 1.3% for chronic tension-type headache. The lifetime prevalence of all migraine and all tension-type headache, including another 84 subjects fulfilling all but one of the criteria for migraine or tension-type headache, was 13.8% and 13.5%, respectively. The corresponding prevalence risk for women was 2.4 (95% confidence interval [CI] 1.7, 3.4) and 1.5 (95% CI 1.1, 2.1), respectively. Zygosity was not a significant predictor for migraine. In tension-type headache, the prevalence risk for dizygotic twins and unlike-sexed twins as compared with monozygotic twins was 1.9 (95% CI: 1.2, 3.1) and 1.8 (95% CI: 1.1, 2.9), respectively. Conclusion.,There is no twin-singleton or monozygotic-dizygotic difference for the risk of migraine. In tension-type headache, twins seem to have a lower risk than singletons, and this is especially true for monozygotic twins. [source] Psychosocial Impact of Headache and Comorbidity with Other Pains among Swedish School AdolescentsHEADACHE, Issue 8 2002Åsa Fichtel MSc Background.,The psychosocial impact of headache combined with other pains has previously been insufficiently investigated. Objective., The present study examined the prevalence of headache, its comorbidity with other pains and psychosocial impact among adolescents. Methods., 793 adolescents in a sample recruited from 8 schools in the middle of Sweden were assessed. Results.,Forty-five percent of the adolescents reported ongoing pain during assessment and more than half of the adolescents reported at least one frequent pain during the previous 6 months. The most common pain among girls was headache (42%), but for boys muscle pain (32%) was most prevalent. Number of pains and perceived pain disability were also higher among girls than boys. One-third of the headache sufferers had headache only, while one-third reported one other frequent pain and the others had at least two other frequent pains. Overall, adolescents with frequent headaches had higher levels of anxiety or depressive symptoms, in addition to functional disability and usage of analgesic medication. Frequent headache sufferers reported more problems in everyday life areas than those with infrequent headaches. Conclusions.,It is recommended that adolescents suffering from recurrent headaches routinely should be asked about the presence of other pains, anxiety and depressive symptoms, medication usage, in addition to psychosocial consequences in their everyday life activities. Longitudinal research is also needed to delineate causal relationships between psychosocial factors and recurrent pains, in particular regarding possible sex differences. [source] Does the Addition of Dexamethasone to Standard Therapy for Acute Migraine Headache Decrease the Incidence of Recurrent Headache for Patients Treated in the Emergency Department?ACADEMIC EMERGENCY MEDICINE, Issue 12 2008A Meta-analysis, Systematic Review of the Literature Abstract Objectives:, Neurogenic inflammation is thought to play a role in the development and perpetuation of migraine headache. The emergency department (ED) administration of dexamethasone in addition to standard antimigraine therapy has been used to decrease the incidence of recurrent headaches at 24 to 72 hours following evaluation. This systematic review details the completed trials that have evaluated the use of dexamethasone in this role. Methods:, The authors searched MEDLINE, EMBASE, CINAHL, LILACS, recent emergency medicine scientific abstracts, and several prepublication trial registries for potential investigations related to the research question. The authors included studies that incorporated randomized, double-blind, placebo-controlled methodology and that were performed in the ED. A fixed-effects and random-effects model was used to obtain summary risk ratios (RRs) and 95% confidence intervals (CIs) for the self-reported outcome of moderate or severe headache on follow-up evaluation. Results:, A pooled analysis of seven trials involving 742 patients suggests a modest but significant benefit when dexamethasone is added to standard antimigraine therapy to reduce the rate of patients with moderate or severe headache on 24- to 72-hour follow-up evaluation (RR = 0.87, 95% CI = 0.80 to 0.95; absolute risk reduction = 9.7%). The treatment of 1,000 patients with acute migraine headache using dexamethasone in addition to standard antimigraine therapy would be expected to prevent 97 patients from experiencing the outcome of moderate or severe headache at 24 to 72 hours after ED evaluation. The sensitivity analysis yielded similar results with sequential trial elimination, indicating that no single trial was responsible for the overall result. Adverse effects related to the administration of a single dose of dexamethasone were infrequent, mild, and transient. Conclusions:, These results suggest that dexamethasone is efficacious in preventing headache recurrence and safe when added to standard treatment for the management of acute migraine headache in the ED.
