Thirty patients suffering from reflex sympathetic dystrophy accompanied by continuous spontaneous pain of the affected distal limb were investigated. The aim of the study was to determine whether a suprasystolic compression (cuff) fixed at the distal part of the affected limb and interrupting the distal circulation would influence the pain. In most cases, this so-called ischaemia-test led to a substantial suppression of pain, which occurred during the first or second minute after the cuff had been applied. Therefore, this test can be used as a new diagnostic tool to support the clinical diagnosis of reflex sympathetic dystrophy.

In 60 women undergoing vaginal hysterectomy, a total of 420 pain evaluations of postoperative pain intensity were performed by an observer and the patients. Pain intensity was rated by the observer on a visual analogue scale. The patients themselves evaluated their pain on a visual analogue scale and on a 101-point numerical rating scale. ⋯ The correlation between patients' self-assessments and observers' ratings was poor (r (2)=0.28;y=0.66x+31.3). There was also no clear correlation between pain intensity and heart rate or arterial blood pressure. A reliable assessment of pain intensity can only be performed by patients' self-assessment and not by observers' ratings.

Different therapeutic modalities are available for the treatment of rheumatic pain. The most important one, besides physiotherapy, is medication with analgesics and adjuvant drugs. Analgesics are given orally and by a stepwise approach in keeping with the principles of cancer pain therapy. ⋯ Patients often suffer from constipation, nausea and vomiting, but these side-effects can be treated with laxatives and antiemetic drugs. There is no reason to differentiate between opioid medication in a cancer patient with pain and in a patient with "non-malignant" rheumatic pain. Centrally acting muscle relaxants may be helpful as adjuvant medication in patients with myalgia for example, and tricyclic antidepressants can also be beneficial, especially in neuropathic pain and for patients with psychiatric distress associated with pain.

The first studies on psychological treatment of pediatric headache appeared about 10 years ago; most of them were published in Anglo-American journals. This review focuses on relaxation training and biofeedback (EMG and hand temperature feedback) as the psychological interventions most often used in pediatric migraine and tension headaches. ⋯ Biofeedback studies are methodologically less well controlled and although positive effects have been observed, e.g., in single case studies, the relative usefulness of biofeedback has yet to be determined. Deficits in research on the psychological treatment of headache in children and adolescents are described, new research issues are discussed and recommendations for more systematic research are given.

Vitamins of the B group have long been used to treat neuropathies of different origins and the accompanying pain. A combination of the vitamins B(1), B(6), and B(12) prevents the slowing of impulse conduction produced by tetanic stimulation in diabetic mice. In patients suffering from diabetic neuropathy, B vitamins alleviate pain in the upper extremities. ⋯ It has recently also been reported that a combination of the vitamins B1, B6, and B12 has analgesic properties in non-neuropathic conditions. In animal experiments, B vitamins diminish nociceptive responses in spinal and thalamic neurones and potentiate the antinociceptive effect of analgesic agents. Similarly, B vitamins potentiate the therapeutic effect of diclofenac in patients suffering from acute low back pain.
