Research tabulating the existence and effects of pain and related factors in the elderly is lacking, in spite of the continued growth of the aged population. Leg pain, in particular, may interfere with activities and interpersonal interactions. This study of 3,097 rural elderly examines the prevalence of complaints of leg pain and related factors in a geographically-defined population. Findings indicate that leg pain is clearly a common experience which impacts daily activities of the elderly.

In a questionnaire survey we determined the prevalence and intensity of muscular symptoms in a group of chronic headache sufferers as compared with age- and sex-matched controls. The muscular symptoms studied were tightness and soreness of the neck, shoulder, and jaw muscles. Muscle tightness was reported significantly more frequently in the headache than in the control group, but only for the neck muscles (48.6 vs. 29.9%; p less than 0.01). ⋯ With regard to the prevalence of muscle soreness, there were no significant differences between the headache and the control groups or within the headache group when headache was absent or present. However, the intensity of muscle soreness was significantly greater for all three muscle groups in the headache group when headache was present than when headache was absent (p less than 0.001). The results indicate significant muscular symptoms in relation to headache, particularly in relation to the neck muscles, with tightness standing out more than soreness.

A study was conducted to determine symptom report patterns in a heterogenous population of orofacial pain patients and to evaluate how symptom patterns relate to various dimensions of the human pain experience. Results indicated that symptoms frequently associated with chronic orofacial pain disorders can be described by four indices related to the temporomandibular joint (TMJ) and its movement; discomfort of and parafunctional activities related to the masticatory muscles; interference of pain with activities of daily living; and presence of orofacial pain unrelated to myogeneous or arthrogenous TMJ disorders. Of these four symptom indices, only the pain interference (symptom) index was related to clinical pain and illness behavior. ⋯ Two of the indices were influenced by diagnosis. Biomechanical symptoms and parafunctional activities appear to be insignificantly related to perceived pain intensity, pain responsiveness, illness behavior, or personality, but are related to diagnosis. The results indicated that relatively simple symptom checklists have potential utility in screening orofacial pain patients and in evaluation of treatment outcome.

The technique of long-term, open catheterization of the spinal subarachnoid space for infusion of analgesics in patients with refractory cancer pain is sparsely reported in the literature. We report on a technique using 18G Portex nylon catheters and 16G-17G Tuohy needles, and its problems and complications. One hundred fifty-seven catheters were inserted in 142 patients, in most of them (79%) under deep sedation and local anesthesia. ⋯ Absorbent and impermeable dressings were applied over the tunnel exit, catheter Luer connection and bacterial filter. Antibiotics were given on the day of insertion and 2 days thereafter. During the insertion procedure, the following problems and complications were encountered; two or more attempts before successful spinal-dural puncture (32%), accidental puncture of an extradural vessel (10%), difficult dural puncture (18%), absence of free dripping of cerebrospinal fluid (CSF) in spite of successful dural puncture (4%), blood-stained CSF (9%), radicular pain and paresthesiae (4%), difficult advancement of the catheter (6%), difficult tunneling (11%), and bleeding in the tunnel (0.7%).(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between pain perception and emotional states is well known. However, the nature of this relationship and how different emotional states affect sensory and cognitive dimensions of pain remains uncertain. Results from experimental investigations are often contradictory, which may be due to methodological difficulties in inducing pain and monitoring physiological responses. ⋯ No differences could be detected for either the happy or the fear-related condition compared with the baseline or neutral hypnotic condition. A significant positive correlation between the subjective intensity of depression and the increase in evoked potentials was found, but none for the other three emotions. The results support earlier findings that clinical depression is related to increased pain perception, and findings that the expression of anger can inhibit the experience of pain.(ABSTRACT TRUNCATED AT 250 WORDS)
