This epidemiological questionnaire-study of 362 patients suffering from chronic pain related to musculoskeletal disorders showed the following results: Most musculoskeletal pain syndromes are located in the head and back areas (57.3%). Patients who seek treatment in an orthopedic pain clinic suffer from at least moderate pain according to the verbal rating scale and from pain equal too or more than 50 on to the numeric rating scale. For most patients (51.9%) the duration of the pain has been between 1 and 10 years. ⋯ Most patients with chronic pain consult 2 to 6 doctors. For typical orthopedic pain syndromes most patients consult an orthopedist. Patients with chronic headaches consult an orthopedic specialist about as frequently as neurologist or internist specialist.

Sufentanil, alfentanil, and fentanyl: impact on cerebrospinal fluid pressure in patients with brain tumors.
In order to evaluate the safety of the new synthetic opioids, alfentanil and sufentanil, in neurosurgical patients, we administered sufentanil 1 microg/kg i.v., alfentanil 50 microg/kg i.v. followed by an infusion of 1 microg/kg/min, or fentanyl 5 microg/kg i.v. to 30 patients with supratentorial tumors anesthetized with nitrous oxide (N2O), 60% in O2. Lumbar cerebrospinal fluid pressure (CSFP) and mean arterial pressure (MAP) responses were recorded for 10 min thereafter, while ventilation was held constant [mean PaCO2 = 36.1 +/- 1.0 mm Hg (SEM)]. There was no change in CSFP after fentanyl. ⋯ It is concluded that because sufentanil increased CSFP in patients who have brain tumors, it also may be contraindicated in other neurosurgical patients at risk for intracranial hypertension. Alfentanil may share this propensity, since CSFP increased despite a profound reduction in MAP. Among the three opioids evaluated, only fentanyl appears to be appropriate for supplementing N2O-2 anesthesia in patients who have compromised intracranial compliance.

The gate control theory resulted in intensified consideration and investigation of psychological factors in the pathogenesis and continuation of chronic pain. This had led to an increasing interest in the efficacy of psychotherapy for such patients. The different forms of psychotherapy (hypnosis, relaxation, behavior therapy, psychodynamically oriented therapy) currently most often applied are reviewed with notes on the methods and the efficacy recorded for each. ⋯ The small numbers of patients evaluated in most of the studies suggest that the population investigated may well not be representative, especially if the difficulty of motivating chronic pain patients to present for psychotherapy is taken into account. In addition, a diagnostic classification of the population investigated is lacking. Conclusions are drawn for the planning of future therapy studies.

During the 1960s, it was observed that the tricyclic antidepressant imipramine was effective in the treatment of neuralgia, myalgia, and pain in carcinoma. Similarly, in other studies, clomipramine was also found to have an analgesic effect. The sedative antidepressant amitriptyline has proved effective in migraine prophylaxis, chronic tension headache, and psychogenic musculoskeletal and neuralgic facial pain. ⋯ The remaining tricyclic and the tetracyclic antidepressants have not been sufficiently well evaluated. This is also true of monoamine oxidase inhibitors, of which individual reports to date suggest are probably also effective as analgesics. A scientific investigation into the possible differences in the effectiveness of various antidepressants in specific chronic pain conditions is an important task for the future.
