Subcutaneous self-administration of morphine with a "pain pen", a semiautomatic mechanical injection system about the size of a penholder, was tested in nine patients with severe chronic pain of malignant origin. During a period of treatment of 12-100 days (on an outpatient basis in three patients) side-effects of subcutaneous morphine could only be observed during a short-lasting initial period of adaptation. ⋯ There were no hygienic problems, and the patients learned the technique of self-injection within a few days. This system may be especially suitable for patients with gastrointestinal incompatibility of oral opiate preparations, e.g. patients with multiple drug intake.

In repeated clinical studies a preponderance of pain syndromes on the left side of the body has frequently been observed. Experimental studies in humans revealed a lower pain threshold on the left, nondominant side. On the other hand, some studies do not confirm this lateralization. ⋯ For pain induced by pressure, lateral asymmetry increased with pain intensity, for the other two methods it was constant. Lateral asymmetry was found in all subjects, but significant differences could only be demonstrated in female Ss. It is concluded that both gender and handedness contribute to lateral asymmetry of pain sensitivity in man.

Tick-borne borreliosis (Borrelia burgdorferi) is a common and complex disorder affecting the skin, the joints and the nervous system. It progresses through different clinical stages. The clinical spectrum of neuroborreliosis has expanded since the introduction and widespread application of specific serological tests. ⋯ Therefore, borreliosis can be assumed to produce a painful skin dystrophy like SRD or ACA by direct injury to the sympathetic nerves even in the early clinical stage of the infection. The main conditions to be considered in the differential diagnosis are polymyalgia rheumatica; lumbar disk herniation; inflammatory radiculopathies of other origin (e.g. herpes zoster); painful neuropathies, including the diabetic thoraco-abdominal form; internal disorders of chest and abdomen with referred pain; lymphocytic meningitis of other origin, encephalomyelitis; and sympathetic reflex dystrophy. High-dose penicillin G i.v. is a potent analgesic in all patients with tick-borne neuroborreliosis.

Migraine is a syndrome and not a nosological entity. It is therefore relatively improbable that a uniform etiology can be defined, and it must be assumed that there are different multifactorial etiological conditions for each individual. It is probable that a therapy concept that is equally valid and promising for all patients can therefore never be developed. ⋯ The intrinsic action of a therapy method should be compared to the placebo effect on a randomized doubleblind basis. If this preconditions is fulfilled, appraisals of the real chances of success in the practice can be made more accurately on the basis of large-scale open studies comprising a representative cross-section of migraine patients. Further topics for therapy studies should include the analysis of responders and nonresponders and the development of differential indications for certain methods of therapy.
