Drug therapy for the prevention of migraine attacks is becoming more and attacks is becoming more and more important. The aims of such prophylactic treatment are to reach a lower frequency, shorter duration and milder intensity of migraine attacks, and to reduce the intake of anti-migraine medication, to improve the quality of life and working ability. The question of efficacy and tolerance of established migraine prophylactics [1] has been thoroughly investigated in many studies. So far the question of sustained efficacy after a successful prophylactic treatment completion has not been a research priority, but it is nonetheless of great importance. Researchers at the neurologic scientific research institute of the university of Naples have followed up migraine out-patients after successful prophylactic treatment and observed that prophylactic agents differ not only in their immediate efficacy and safety, but also in long-term efficacy. Therefore, an open pilot study was performed with the prophylactic agents propranolol, flunarizine, pizotifen, DHE retard, methysergide and cyclandelate in the recommended dossages (Tabe 1). ⋯ In spite of the uncontrolled pilot design, it can be said in summary that all prophylactic drugs were effective. Cyclandelate had a good safety profile, and in efficacy it was at least comparable to the other prophylactic drugs. Patients treated with cyclandelate had a longer duration of active treatment and likewise a longer period of follow up. In addition, the proportion of patients with "no indication for repeated prophylaxis" at follow up was higher than for any of the other drugs. The results are interesting for medical practice and suggest replication in a randomized blind study. If the results yielded by the present study are confirmed, cyclandelate should be classified as a drug of first choice for migraine prophylaxis.

Local wound perfusion with bupivacaine after elective abdominal surgery seems to be a promising method of reducing postoperative pain. Applicability, effectiveness, side effects and risks were tested in a pilot study with 28 patients. During closure of the laparotomy incision two catheters were inserted, one between peritoneum and fascia and the other subcutaneously. ⋯ No severe side effects occurred, but the study was interrupted nonetheless in 3 patients, 2 of whom had a transit syndrome while the third had more severe hypotension than could be explained by the bupivacaine blood level. No infections and no problems with wound healing occurred during the study. This study proved that the method tested leads to significant pain reduction after elective abdominal surgery and has no severe side effects.

In rheumatology, all of the more than 400 specified syndromes are associated with pain. In the conceptual discussion on the multidimensional influences postulated to explain the development of chronic pain, fibromyalgia has gained increasing interest. Fibromyalgia (fibrositis) is an unspecific soft-tissue disorder with chronic wide-spread musculoskeletal pain and palpable hypersensitivity at fibrositic tender points. ⋯ Histochemical investigations on muscle biopsy and biochemical tests have revealed unspecific changes but no characteristic muscle abnormality. It is supposed that the clinical features may result from central neurohumoral dysfunction combining with peripheral mechanisms to result in hyperalgesia. An integrated therapeutic concept with a reassuring and positive doctor-patient relationship can be helpful in achieving satisfactory treatment results.

The possible association of brain tumour with headache was investigated in 100 patients seen for brain surgery. Preoperatively, 43 patients suffered from headache. These patients were thoroughly questioned about the nature of their pain. Investigation included the McGill Pain Questionnaire. ⋯ Our investigations yielded new information concerning the epidemology of headache accompanying brain tumours. Headache is not an early cardinal symptom of brain tumours, as was generally believed earlier. With the help of the McGill Pain Questionnaire a fine quantitative and qualitative characterization of headache of different origins could be made. The connection between tumour localization and pain lateralization, as well as the possible mechanisms of intracranial pain projection was extensively analysed. The interpretations of the results are at best hypotheses and they do not help determine why more than half of the patients with brain tumour did not experience headache.
