During a semi-structured interview 82 migraine patients were asked biographical and illnessrelated questions. They completed psychological instruments on coping behavior (Stressverarbeitungsfragebogen), self-concept (Frankfurter Selbstkonzeptskalen), attributional style (IE-SV-F), illness behavior, and illness-related attributions (Tübinger Attributions-fragebogen). The theoretical background of this research is a cognitive model of coping with stress and illness. ⋯ Some of the pain behavior strategies could be identified as being focused on illness (guarding behavior, avoidance and social withdrawal, resignation and complaint); only the attempt to relax is regarded as being focused on health. Migraine patients show a preference neither for medical nor psychological causal attributions of their illness but score significantly higher on medical than psychological control attributions. The results have implications for psychological therapy.

A randomized, double-blind study was performed to test the analgesic effect of salmon calcitonin (sCT). The pain threshold of ten healthy subjects was measured during electrical stimulation of the dental pulp. Each subject underwent four different tests, whereby sCT at doses of 50 IU, 100 IU and 200 IU or placebo was administered subcutaneously. ⋯ The maximal threshold change was also significantly dependent on the dosage: with placebo the maximal change was 4 mA, while with sCT 50, sCT 100, and sCT 200 it was 14, 17 and 18 mA, respectively. The plasma levels of sCT and its analgesic activity were significantly correlated, as was demonstrated by means of linear regression based upon the bilogarithmic transformation of the plasma concentration. Altogether, the results prove conclusively that calcitonin given systemically possesses primary analgesic efficacy, a property that fits well into its spectrum of activity in the treatment of (painful) bone diseases.
