A 21-year-old man suffered from diffuse low back pain and sciatica for 10-s periods once or twice a day over a period of 6 months. After this, pain became chronic and was resistant to conventional conservative treatment. Only acetylsalicylic acid diminished pain. ⋯ The time between onset of symptoms and final diagnosis was 18 months. Symptoms disappeared after surgery. Clinical and radiological aspects of the case are discussed.

Realizing that achievement in postoperative pain treatment was not satisfactory, central health authorities in USA, United Kingdom and Australia have published guidelines for managing acute pain. Establishing acute pain services is thought to be one of the means of improving pain relief in the individual patient. ⋯ At this moment, introduction of acute pain services is at a preliminary stage in Denmark, and consequently an overview of results obtained from abroad is given including pain treatment techniques, management and safety measures, as well as visions concerning the impact of optimal pain relief upon convalescence. We conclude that the introduction of acute pain services is bound to optimize postoperative patient care and might well prove to be a significant factor in reducing postoperative morbidity.

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.

Tolerance to the mydriatic effect of buprenorphine, butorphanol, nalbuphine, and cyclorphan, and cross-tolerance to morphine in mice.
An increase in the use of opioid derivatives in the treatment of pain syndrome in clinical practice, and especially in the treatment of cancer, has added impetus to the search for an agent which does not induce tolerance and cross-tolerance to other opiodis. The mydriatic effect of opioids in mice, the correlation between analgesia and mydriasis, and tolerance to the analgesic effect of morphine in mice were evaluated previously. ⋯ Tolerance and cross-tolerance to morphine were developed following a chronic use of buprenorphine, nalbuphine, and cyclorphan. After chronic injection of butorphanol, no tolerance or cross-tolerance to morphine was observed.
