Randomized Controlled Trial Multicenter Study
Topiramate reduces headache days in chronic migraine: a randomized, double-blind, placebo-controlled study.
The aim of this study was to evaluate the efficacy and tolerability of topiramate for the prevention of chronic migraine in a randomized, double-blind, placebo-controlled trial. Chronic migraine is a common form of disabling headache presenting in headache subspecialty practice. Preventive treatments are essential for chronic migraine management, although there are few or no controlled empirical trial data on their use in this patient population. ⋯ Treatment emergent adverse events were reported by 75% of topiramate-treated patients (37%, placebo). The most common AEs, paraesthesia, nausea, dizziness, dyspepsia, fatigue, anorexia and disturbance in attention, were reported by 53%, 9%, 6%, 6%, 6%, 6% and 6% of topiramate-treated patients, respectively, vs. 7%, 0%, 0%, 0%, 0%, 4% and 4% of placebo-treated patients. This randomized, double-blind, placebo-controlled trial demonstrates that topiramate is effective and reasonably well tolerated when used for the preventive treatment of chronic migraine, even in the presence of medication overuse.

Randomized Controlled Trial Clinical Trial
Magnetic resonance angiography shows dilatation of the middle cerebral artery after infusion of glyceryl trinitrate in healthy volunteers.
Previous studies have reported dilatation of the middle cerebral artery (MCA) during acute glyceryl trinitrate (GTN)-induced headache, using imaging techniques such as transcranial Doppler (TCD), positron emission tomography (PET) and single photon emission computerized tomography (SPECT). In the present study we aimed to evaluate whether magnetic resonance angiography (MRA) may be used to examine the effect of GTN on the MCA, with respect to changes in diameter and cross-sectional area in healthy volunteers. In addition, we wanted to determine the intra- and inter-observer variation of the method. ⋯ The intra-observer variation (day-to-day) at baseline was 8.3% and 10.9% for the two observers. The mean inter-observer variation of the cross-sectional MCA area was 15.5% and for the diameter measurements 8%. The present study shows that the MRA method gives a reliable semi-quantitative index of the vascular changes in the intra-cerebral arteries after infusion of GTN and may be useful for headache research.

Randomized Controlled Trial Comparative Study Clinical Trial
Chronic tension-type headache treated with acupuncture, physical training and relaxation training. Between-group differences.
The aim of this study was to compare acupuncture, relaxation training and physical training in the treatment of chronic tension-type headache (CTTH). The study comprised 90 consecutive patients with CTTH who were randomly allocated to acupuncture, relaxation training or physical training. Headache intensity, headache-free days and headache-free periods were registered using a visual analogue scale and a headache diary. ⋯ Immediately after the last treatment, the number of headache-free periods and of headache-free days was higher in the relaxation group compared with the acupuncture group. There were no other significant differences between the groups at any time point. The clinical implications of our findings are that relaxation training induced the most pronounced effects directly after the treatment period, compared with acupuncture and physical training.

Randomized Controlled Trial
Advice alone vs. structured detoxification programmes for medication overuse headache: a prospective, randomized, open-label trial in transformed migraine patients with low medical needs.
The aim of this study was to compare the effectiveness of strong advice to withdraw the overused medication with the effectiveness of two structured pharmacological detoxification strategies in a cohort of patients diagnosed with probable migraine overuse headache (MOH) plus migraine and presenting low medical needs. One hundred and twenty patients participated in the study. Exclusion criteria included: previous detoxification treatments, coexistent medical or psychiatric illnesses and overuse of agents containing opioids, benzodiazepines and barbiturates. ⋯ Withdrawal therapy was considered successful if, after 2 months, the patient had reverted to an episodic pattern of headache and to an intake of symptomatic medication on fewer than 10 days/month. We were able to detoxify 75.4% of the whole cohort, 77.5% of patients in group A, 71.7% of patients in group B and 76.9% of those in group C (P>0.05). In patients with migraine plus MOH and low medical needs, effective drug withdrawal may be obtained through the imparting of advice alone.

Randomized Controlled Trial Multicenter Study
Efficacy of physiotherapy including a craniocervical training programme for tension-type headache; a randomized clinical trial.
We conducted a multicentre, randomized controlled trial with blinded outcome assessment. The treatment period was 6 weeks with follow-up assessment immediately thereafter and after 6 months. The objective was to determine the effectiveness of a craniocervical training programme combined with physiotherapy for tension-type headache. ⋯ Effect sizes were large and clinically relevant. Loss to follow-up amounted to 3.7%. Physiotherapy including craniocervical training reduces symptoms of tension-type headache significantly over a prolonged time frame.
