It has been widely recognized that an appreciable proportion of chronic pain patients have depressive disorders. Although numerous studies and several literature reviews have examined the relationship between chronic pain and depression, disorders of mood come in many forms, and little attention has been paid to the different types of depressive disorders found among patients with chronic pain. In this article, the different ways in which a chronic pain patient may manifest depression are discussed. ⋯ The medical illnesses and medications that can cause symptoms of depressive disorders are also briefly described. Depressive disorders and their concomitants are an integral part of the experience of chronic pain and are important in developing an optimal treatment plan. For these reasons, they should be carefully evaluated in all patients with chronic pain.

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.

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.
