Estimates of the prevalence of essential tremor (ET) are probably low because screening questionnaires have been used. The authors estimated the prevalence of ET in Mersin Province, Turkey, in 2,253 individuals aged >or=40 years, all of whom were examined by study neurologists. There were 89 ET cases (prevalence = 4.0%, 95% CI = 3.2 to 4.8%). The prevalence of ET may be higher than previously estimated. This is important when defining the extent of the health care problem.
The discrepancy in RLS prevalence studies (including the authors') suggests that prevalence varies among different races, thus supporting a genetic predisposition.
The objectives of the present study were to estimate the prevalence of recurrent headaches in schoolchildren (ranging from 2nd to 5th degrees) in Mersin city of Turkey and to determine the sensitivity, specificity, positive predictive value and positive likelihood ratio of the diagnostic headache characteristics in children with migraine and Tension Type Headache (TTH) using neurologist's diagnosis as the gold standard. The stratified sample of study was composed of 5562 children. The prevalence of recurrent headache was 49.2% (2739 of 5562) and the prevalence of current headache was 31.3% (859 of 2739). TTH was more common than migraine (24.7% vs. 10.4%). The most sensitive headache characteristic for migraine was 'severity of pain' and the most sensitive definitive symptom is 'duration of headache' in children with TTH. IHS-based symptom definition criteria are highly beneficial in diagnosis of childhood headache, if used together with detailed clinical assessment.
We present the clinical findings of a group of largely undiagnosed and untreated population-dwelling ET cases that would not otherwise have come to neurological attention. Approximately one-half reported functional difficulty and psychiatric symptoms were over-represented in these ET cases compared with matched controls. These findings suggest that ET, as it exists in the population, is not a completely benign entity.
Headache is a common health problem among schoolchildren in Mersin, which merits increased attention and detailed multicentre epidemiological and clinical studies.
This cross-sectional clinical study was conducted in order to explore the relationship between atopic disorders and migraine. We evaluated 186 consecutive patients with migraine. Patients with a history of atopic disorders were compared with the others during headache-free intervals, for their headache characteristics, pulmonary test (PFT) performances and immunological screenings, through appropriate statistical methods. Of the patients with migraine, 77 (41.4%) reported at least one atopic disorder. PFT screening showed a general decreased pulmonary capacity and an important correlation between a positive history of atopic disorders and both increased eosinophil and IgE levels in headache-free periods. It should be discussed whether screening with PFT or immunological tests helps in early detection of progressive lung disease which might develop in these patients.
Headache is a common problem among adolescents, and variations can be observed in headache types and characteristics. The present study aimed to reach 5562 Turkish children who were investigated six years previously in a school-based childhood headache project, and to evaluate their current headache status. Investigators interviewed the available students with structured questionnaires. New and old data were matched and analyzed. The present study included 1155 adolescents (mean age 15.2 +/- 1.1 years), with 582 boys (50.4%) and 573 girls (49.6%). The prevalence of headache was 78.7% (tension-type headache [TTH] 57.5%, migraine 18.6%, unspecified 2.6%). The prevalence of headache was 45.2% six years previously. In the intervening six years, headache prevalence increased and the headache types changed significantly (Kappa: 0.04, p < .01). The most important variation during this time was the significant increase in TTH. Analgesic use was determined in 70.2% of adolescents with headache, with this ratio being higher in migraineurs. In conclusion, there were an increase in headache prevalence and a significant change in headache types over the previous six years. It can also be suggested that new country-based management strategies are required.
To evaluate the long-term efficacy of non-surgical treatment methods for mild and moderate carpal tunnel syndrome, 120 patients with clinical symptoms and electrophysiologic evidence were included in a prospective, randomized and blinded trial: 60 patients were instructed to wear splints every night, 30 received injections of betamethasone 4 cm proximal to the carpal tunnel, and 30 received injections distal to the carpal tunnel. After approximately 1 year (mean, 11 months; range, 9-14), 108 patients were available for final evaluation. We assessed clinical symptom severity and performed detailed electrophysiologic examinations before and after treatment. Splinting provided symptomatic relief and improved sensory and motor nerve conduction velocities at the long-term follow-up when the splints were worn almost every night. Proximal and distal injections of steroids were ineffective on the basis of both clinical symptoms and electrophysiologic findings.
