In pain clinics, thorough documentation of patient-related data is essential for analysis of patient history, long-term evaluation of diagnostic and therapeutic procedures, and research on the etiology and epidemiology of chronic pain syndromes. With these requirements in mind, we realized a microcomputer documentation system based on a commercial data-base software concept (dBASE). Each patient's data are stored in three different sections: data for identification, basic data (mainly diagnostic findings), and treatment related follow-up data. ⋯ The microcomputer documentation system offers listings for administration as well as effective patient scheduling thanks to a recall system by date of last contact, selected therapeutic procedures and any other item in the medical record. A mail-merge service can be applied, which is particularly useful for follow-up-studies. The documentation system means routine work can be standardized and performed in an economical manner, with the ultimate aim of enhancing the quality of pain therapy.

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.

Tursky's pain perception profile [16] has been revised and adapted for use in German-speaking conditions, and this new modification is presented. It integrates six different methods of clinical and experimental methods of clinical and experimental pain measurement, which are intended to meet the enhanced demands put forward in pain research for multivariate measurement of pain by a variety of methods. ⋯ The results document the many aspects of chronic pain and the necessity for multimodal measurement. In addition, they supply a means of achieving a better pain-related classification of pain patients on an experimental basis.

Reflex sympathetic dystrophy (RSD) is a disease of the extremities that can be elicited by different factors, occurring at different sites (e.g., trauma, herpes zoster, myocardial infarction). Independently of its etiology, however, the clinical symptoms of RSD are found most often in distal parts of the extremities affected (hand or foot). In a generalized distribution pattern, the following signs, representing a triad of autonomic, motoric and sensory disturbances, are commonly observed in these regions: 1. dysregulation of blood flow to the skin and of sweating, together with diffuse swelling, 2. impairment of movement and muscular strength; 3. diffuse sensory skin disturbances and spontaneous pain of ariable character (e.g., burning, throbbing, aching, shooting). ⋯ This excitation, in turn, maintains the abnormal vasoconstrictor outflow via reflex mechanisms, thus initiating a vicious circle. Sympatholytic therapy can interrupt the abnormal vasoconstrictor outflow, leading to increased venous return and reducing interstitial pressure and nociceptor activation (interruption of the vicious circle). If sympatholytic therapy is applied early, full recovery may occur.

Conventional clinical dosages of local anesthetics may not be sufficient to block conduction of all afferent impulses, which is important for an effective epidural sensory blockade. Further depression of the transmission of information can be accomplished by central modulating mechanisms, preventing sensory perception. Since there are interindividual differences in the quality of modulating mechanisms, standardized depression of impulse propagation by the local anesthetic is associated with a wide variation in the total depression of afferent impulses. ⋯ Patients with a low pain threshold require a more highly concentrated local anesthetic. The addition of opioids to the local anesthetic will permit the use of lower concentrations of the local anesthetic itself. Optimal use of diagnostic, prognostic, and therapeutic epidural blockades is possible only if the influence of modulating mechanisms is taken into account.
