An increasing number of papers deal with immunological factors in headache syndromes such as migraine and cluster headache. The aim of this review is to give an overview of the factors that have been measured and to assess their reliability and relevance for the pathogenesis of these headaches. Most of the studies are handicapped by methodological problems, especially the different classifications of headaches, the lack of adequate controls and methodological problems with the measurement of certain immune parameters. ⋯ Although the immunological changes have been shown to be valid, their pathogenesis in these headaches is unclear. With the increasing recognition of the existence of a neuroimmunologic network, alterations in each system should always be considered to be associated with changes in an other. Acute or chronic pain seems to trigger immunological abnormalities.

Many studies investigated patient-controlled analgesia (PCA) in the postoperative period in recovery rooms under anaesthesiologic monitoring but reports on the advantages and indications of PCA in surgical wards are scarce. The aim of this prospective study therefore was to investigate PCA as a routine technique in surgical wards. In particular we were interested in safety and in the efficacy of analgesia. ⋯ We conclude that PCA with piritramide is a safe technique when performed under routine conditions on surgical wards. However, standardized monitoring is mandatory. PCA leads to effective analgesia and consequently to greater comfort of surgical patients in the postoperative period. These conclusions hold only for patients with ASA status I-II who have undergone operations of the types listed above.

Up to 70% of cancer patients in the terminal phase of their disease complain of moderate or severe pain. Pain therapy in these patients follows the analgesic ladder of the WHO. Many cancer patients will need a strong opioid to get sufficient pain relief. ⋯ The transdermal application of a strong opioid may be an alternative, especially for patients with cancer of the head and neck or in the gastrointestinal tract. Because of the pharmacokinetic laziness of the system the use of Fentanyl-TTS should be limited to patients with stable tumor pain. In these patients Fentanyl-TTS might be valuabe on step III of the analgesic ladder of the WHO or as an alternative to invasive methods when it is impossible to administer oral opioids.

The period of late exteroceptive suppression (ES 2) of the temporalis muscle is often shortened in patients with chronic tension-type headache. The present study was conducted to find out whether the ES 2 is influenced by muscle relaxation training and whether it is rather a state or a trait marker. ⋯ The duration of ES 2 was modified by a muscle relaxation training in patients with chronic tension-type headache. Therefore, ES 2 is a state marker and is probably influenced by limbic structures. Measurement of ES 2 may not be only a diagnostic tool, but could also be useful in monitoring results of therapy in patients with tension-type headache.
