Myofascial pain syndromes, fibromyalgia, and articular dysfunctions may all be contributing to our patients' ubiquitous musculoskeletal pain problems that generally are poorly understood and poorly managed. Thepectoralis minor myofascial pain syndrome, for example, results from trigger points (TrPs) activated by stress overload of the muscle. ⋯ Snapping palpation at the TrP elicits a local twitch response (LTR). The increased muscle tension of a pectoralis minor syndrome commonly entraps the lower trunk of the brachial plexus, producing symptoms of a cervical radiculopathy.

In clinical pychology, the Gate Control Theory of pain (GCT) is considered a milestone among the psychological approaches to pain. In this paper ten critical issues are raised against the GCT. It is argued that GCT should be abandoned as a basis for the psychological study of pain. ⋯ Second, the methodological consequences that accompany the model are considered. Third, research evidence on the validity of the model is given, in particular with regard to the relationship between pain experience and subjective stress, as well as between pain experience and coping with the pain. Finally, further research questions are formulated.

In this study carried out in a sample of 80 patients suffering from rheumatoid arthritis (RA) tried an attempt was made to answer the following questions: 1. are there pain factors with a wider range that are more generally applicable than those covered by current German questionnaires? 2. To what extent can somatic parameters predict pain factors? 3. To what extent can a patient's pain behavior (a patient's activity scores) predict pain factors? The study was based on data collected by means of the Pain Experience Questionnaire (PEQ), the McGill Pain Questionnaire MPQ, the West Haven-Yale Multidimensional Pain Inventory WHYMPI, the Measurement Of Patient Outcome Scale MOPO, as well as six different clinical parameters. ⋯ At a statistically significant level, the first factor can be predicted by the clinical variables. Regression of the activity scores on the factor "socio-emotional consequences" suggests a close correlation between the two variables, although the results failed to reach statistical significance. On the whole, the results strongly support the notion of integrating clinical, behavioral and cognitive findings in the diagnostic assessment of chronic rheumatoid pain patients.

Many studies have demonstrated that cancer pain can be relieved in most cases by suitable analgesic medication. Patients with a diagnosis of "intractable cancer pain", however, are referred to our pain clinic nearly every day. A retrospective study of 1140 patients was therefore performed to evaluate the pain mechanisms and whether analgesic pretreatment had been adequate. ⋯ The principal causes for the inadequacy of the analgesic pretreatment were: failure to prescribe analgesics (10% of the patients), irregular intake schedule or prolonged intervals between applications (66%), underdosage of nonopioid analgesics (27%) or opioids (42%), and withholding of nonopioid analgesics (30%), strong opioids (14%), or co-analgesic drugs (17%), although their prescription was indicated. The severe pain was thus caused in many patients by simple mistakes in the prescription of analgesics. Terms like "intractable" should be used with caution when referring to cancer pain because they are often unreflected and can make patients and physicians feel helpless or insecure.

The problem of nociception and pain development in radicular pain syndromes is not clarified. In the pathophysiology of pain of radicular compression caused by stenosis or disc prolapse, morphological complex nerve root/ganglion is the key structure. Chronic compression forces on the nerve structure cause structural changes. ⋯ The membrane threshold shift in nociceptive fibers is an important prerequisite for pain perception in nerve root compression. New biochemical aspects in the pathophysiology of radicular syndromes are presented, which could explain the discrepancy between pain and objective clinical findings. The article concludes that a better understanding of the nerve root pathophysiology will bring a more differentiated pain-management strategy.
