Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Acute treatment of migraine attacks: efficacy and safety of a nonsteroidal anti-inflammatory drug, diclofenac-potassium, in comparison to oral sumatriptan and placebo. The Diclofenac-K/Sumatriptan Migraine Study Group.
Migraine attacks are often treated with simple analgesics or with ergotamine-containing preparations alone or in combination with anti-emetics. Although also sometimes used to treat migraine, nonsteroidal anti-inflammatory drugs (NSAIDs) have not been systematically evaluated in controlled clinical trials, particularly in comparison with the newer drug sumatriptan. Sumatriptan is a specific migraine treatment which has recently become among the most widely prescribed acute migraine therapies. However, while effective, it has low oral bioavailability and some problematic adverse effects. Diclofenac-potassium is a potent NSAID available as a fast-acting oral tablet, which has been shown to be safe and effective in several other acute pain indications. In the clinical trial reported here, the efficacy and safety of diclofenac-potassium in the acute treatment of migraine attacks has been tested in comparison with oral sumatriptan and placebo. ⋯ Compared with placebo and the reference therapy sumatriptan, diclofenac-potassium is an effective, fast-acting, and well-tolerated acute oral therapy for migraine attacks, with advantages over oral sumatriptan in terms of onset of analgesic effect, reduction of accompanying symptoms, and tolerability profile. It may therefore be useful as an alternative oral therapy for migraine attacks.

Clinical Trial
Pressure pain threshold and pain tolerance in episodic tension-type headache do not depend on the presence of headache.
Pressure pain thresholds and responses to painful mechanical stimuli were obtained from 20 subjects with episodic tension-type headaches (TTH). Tender points in the temporalis and trapezius muscles were studied, along with two nontender points, one in the temporalis and one on the Achilles tendon. Two examinations were performed, one during and one without a headache, and results were compared. ⋯ The data demonstrate that the sensitivity level of these points does not differ based on the presence or absence of TTH. This suggests that the muscle sensitivity in TTH is constant. The observation that the sensitivity levels of both tender and nontender points did not vary suggests that the underlying mechanism or effect of TTH is not restricted to tender muscles.

Psychological factors are important in the chronification and aggravation of headaches. We studied 90 patients suffering from migraine, chronic daily headache (CDH) evolved from migraine, and episodic or chronic tension-type headache (TTH). Emotional, cognitive, and behavioral pain coping were assessed using the Kiel Pain Inventory (KPI), Beck's Depression Inventory, the State-Trait-Anxiety Inventory, and Quality of Life Questionnaire. ⋯ The predictor variable for transformation of migraine was impairment of well-being/quality of life, and for transformation of TTH, the frequency of headaches and depression. Finally, analgesic misuse seems to be less important for chronification and transformation of headaches than the degree of psychological disability. This study draws attention to the role of psychological factors in the chronification of TTH and transformation of migraine and provides some recommendations for the behavioral treatment of chronic headaches.

Randomized Controlled Trial Clinical Trial
Significant reduction in post-lumbar puncture headache using an atraumatic needle. A double-blind, controlled clinical trial.
A characteristic headache occurs in about 36-55% of patients after lumbar puncture, and many of these patients need bed rest for one or more days to get relief. In a double-blind randomized trial we compared a new 22-gauge atraumatic puncture needle with the most widely used 20-gauge "conventional" needle. In 49 patients randomized to the atraumatic needle, post-lumbar puncture headache occurred in 6%, whereas in the 50 patients randomized to the conventional needle this occurred in 32% (p = 0.001). On the basis of these results we recommend use of the atraumatic needle in order to diminish the frequency of post-lumbar puncture headache.
