A review of studies on migraine therapy shows a large heterogeneity in the clinical evaluation of different drugs and behavioral approaches. The percentages of efficacy of beta-blockers or behavior therapy (relaxation, biofeedback) range from 30% to 80%. Methodological differences from one author to another in the design and conduct of the studies might be causes of this variation. ⋯ Double-blind and placebo-controlled studies are often required, but this demand often cannot be niet in empirical reality because of the individuality of the patient or the heterogeneity of the symptoms. We discuss some alternative approaches that could be used in empirical research on headache therapy. The application of single-case experiments as well as methods of time-series analysis are described as a more appropriate approach to the evaluation of studies on chronic headaches.

Migraine is a syndrome and not a nosological entity. It is therefore relatively improbable that a uniform etiology can be defined, and it must be assumed that there are different multifactorial etiological conditions for each individual. It is probable that a therapy concept that is equally valid and promising for all patients can therefore never be developed. ⋯ The intrinsic action of a therapy method should be compared to the placebo effect on a randomized doubleblind basis. If this preconditions is fulfilled, appraisals of the real chances of success in the practice can be made more accurately on the basis of large-scale open studies comprising a representative cross-section of migraine patients. Further topics for therapy studies should include the analysis of responders and nonresponders and the development of differential indications for certain methods of therapy.

A short survey about the different methods available for producing postoperative analgesia is given, the goal being to make it clear to the clinician that there are quite a number of techniques to be used although the everyday clinical practice often sticks to simple and not too effective methods of pain treatment following surgery. Initially presenting short informations about the neurophysiology of pain and the pathogenesis and causes of postoperative pain two main groups of producing analgesia are then discussed. Thefirst group deals with the systemic use of analgesics be it nonnarcotic analgesic antipyretics or narcotic analgesics (opioids). ⋯ They present clear advantages over the local anesthetic methods as there are the long lasting analgesia and the selective blockade of pain not touching motor and sympathetic nerve fibers. A delayed respiratory depression however might be a serious danger showing an incidence of 0,3% in the epidural and some 10% in the subarachnoid route. Aiming to inform the clinician once again about the vast field of possibilities available to make the postoperative course painfree it is hoped that this important task in the postoperative period will be handled with more consequence and effectivity in the future.
