Multicenter Study Clinical Trial
Use of complementary and alternative medicine in patients suffering from primary headache disorders.
Complementary and alternative medicine (CAM) is increasingly common in the treatment of primary headache disorders despite lack of evidence for efficacy in most modalities. A systematic questionnaire-based survey of CAM therapy was conducted in 432 patients who attended seven tertiary headache out-patient clinics in Germany and Austria. Use of CAM was reported by the majority (81.7%) of patients. ⋯ There were no differences with respect to gender, headache diagnoses, headache-specific disability, education, income, religious attitudes or satisfaction with conventional attack therapy. A higher number of headache days, longer duration of headache treatment, higher personal costs, and use of CAM for other diseases predicted a higher number of used CAM treatments. This study confirms that CAM is widely used among primary headache patients, mostly in combination with standard care.

Controlled Clinical Trial
Ictal and interictal phonophobia in migraine-a quantitative controlled study.
The aim of the study was to evaluate quantitatively ictal and interictal phonophobia in episodic migraine (EM). We included subjects with EM and age- and gender-matched controls. Sound stimuli were pure tones at frequencies of 1000, 4000 and 8000 Hz. ⋯ Interictal mean SAT of migraineurs, averaged for the three frequencies, was significantly lower than that of controls [90.4 (0.8) dB vs. 105.9 (1.1) dB, respectively, P < 0.0001]. In migraineurs, mean ictal SAT, averaged for the three frequencies, was significantly lower than interictal SAT [76.0 (0.9) dB vs. 91.0 (0.8) dB, respectively, P < 0.0001]. Patients with EM exhibit increased sound aversion between attacks that is further augmented during an acute attack.

Visual analogue scales (VAS) are well-validated instruments for assessing pain intensity, but have an impractical format. The aim of the study was to validate a vertical against a horizontal VAS for pain intensity registration. Out-patients with headache or non-headache pain were included. ⋯ Correlation coefficients were > 0.95. Bland-Altman analysis showed good agreement between vertical and horizontal scores with correlation coefficients > 0.84. A vertical VAS is equally valid as a horizontal VAS for registration of pain intensity in headache and non-headache patients.

Migraine is a common headache disorder that is increasingly being evaluated in population-based studies. The American Migraine Study II and the Women's Health Study (WHS) have successfully used 'modified' International Classification of Headache Disorders, 1st edition (ICHD-I) criteria to classify patients. Investigating agreement of self-reported migraine in large epidemiological studies with the criteria of the revised version [International Classification of Headache Disorders, 2nd edition (ICHD-II)] is sparse. ⋯ In this sub-cohort, we confirmed self-reported migraine in > 87% of women when applying the ICHD-II criteria for migraine (71.5%) and probable migraine without aura (16.2%). In conclusion, there is excellent agreement between self-reported migraine and ICHD-II-based migraine classification in the WHS. In addition, questionnaire-based migraine assessment according to full ICHD-II criteria in large population-based studies is feasible.

To delineate the differences in clinical characteristics and evaluate the outcome between primary and secondary cough headache, 83 consecutive patients (59M/24F, mean age 61.5 +/- 17.7 years) with cough headache (1.2%) out of 7100 patients in a headache clinic were studied. All of them received brain imaging studies. Most did not have relevant brain lesions (n = 74, 89.2%, primary group) except for nine patients (10.8%, the secondary group). ⋯ Inconsistent with the proposed International Classification of Headache Disorders, 2nd edn criteria, 10.8% of patients with primary cough headache had headache duration of > 30 min. Clinical features, neurological examinations and drug response could not safely differentiate primary from secondary cough headache. Neuroimaging studies are required in each patient.
