Ovarian hormones, age and pubertal development and their association with days of headache onset in girls with migraine: An observational cohort study.

Background Fifty-three percent of adolescent girls report headaches at the onset of menses, suggesting fluctuations of ovarian hormones trigger migraine during puberty. Aims To determine if urinary metabolites of estrogen and progesterone are associated with days of headache onset (HO) or severity in girls with migraine. Methods This was a pilot study and included 34 girls with migraine balanced across three age strata (pre-pubertal (8-11), pubertal (12-15), and post-pubertal (16-17) years of age). They collected daily urine samples and recorded the occurrence and severity of headache in a daily diary. Urine samples were assayed for estrone glucuronide (E1G) and pregnandiol glucuronide (PdG) and the daily change was calculated (ΔE1G, ΔPdG). Pubertal development was assessed by age, pubertal development score (PDS), and menstrual cycle variance. The primary outcome measures were HO days and headache severity. Generalized linear mixed models were used, and included the hormonal variables and three different representations of pubertal development as covariates. Results Models of HO days demonstrate a significant age*PdG interaction (OR 0.85 [95% CI 0.75, 0.97]) for a 1 standard deviation increase in PdG and three-year increase in age. A separate model showed a significant PDS*PdG interaction (OR -0.85 [95% CI; 0.76, 0.95]). ΔPDG was associated with headache severity in unadjusted models ( p < 0.017). Conclusion Age and pubertal development could moderate the effect of ovarian hormones on days of headache onset in girls with migraine.

Inpatient treatment of status migraine with dihydroergotamine in children and adolescents.

OBJECTIVE: To assess the effectiveness of aggressive therapy of status migraine in children and adolescents. BACKGROUND: Inpatient management of pediatric status migraine and intractable headache is limited because of a lack of studies and guidelines. Adult treatment is often based on anecdotal experience, although a few controlled studies have been reported. Added to that is the discomfort of general pediatricians and neurologists in using available effective treatments in pediatric patients (such as dihydroergotamine: DHE). METHODS: Charts of all patients admitted to the neurology service, at Cincinnati Children's Hospital Medical Center-Department of Neurology, for inpatient treatment for intractable headache/status migraine over a 6-week period were reviewed. Demographics, evaluation, diagnosis, and treatment used were tabulated. Data on the effectiveness of the treatments provided were evaluated. Thirty-two total consecutive charts were retrospectively reviewed during that period. RESULTS: Upon discharge, 74.4% of the patients were headache-free. The mean severity of the pain upon discharge was 1.02 +/- 2.22 (using the 0-10 pain scale). CONCLUSION: From our review, DHE is very effective in treating and aborting an episode of status migraine and should be offered to children and adolescent patients who have failed their usual abortive therapy to prevent further severe disability that mainly affects their schooling and social activities.
