Current pain and headache reports

Although cluster headache (CH) has been the focus of a great deal of research, it also has been the focus of a great deal of speculations that have been repeated commonly as fact. The authors conducted a thorough review of the literature and an informal poll of several noted headache experts to investigate the truth behind common myths and hypotheses regarding CH. They then present an overview of some of these more common hypotheses, observations, and myths, and offer a brief review of the existing evidence supporting or negating the theories. These include gender, genetics, suicidality, homicidality, physical appearance, personality, and psychologic features of the patient with CH.

The experience of chronic pain can be associated with significant distress and disability; however, this is not always the case. Although attempts to control or reduce pain can be helpful for many pain sufferers, on some occasions this is not an effective option and a different response is required. ⋯ At least 15 laboratory and clinical studies make the growing case for the role of acceptance in the functioning of people with chronic pain, and evidence from treatment outcome studies is promising. It appears that acceptance-related processes will at least expand our range of psychologic treatment methods for chronic pain sufferers and, at best, significantly improve them.

For decades, glucocorticoid therapy has been a well-recognized abortive treatment for cluster headaches. However, the role of steroid hormones, including both glucocorticoids and sex steroids, in the pathophysiology and therapy of cluster headaches has been a topic of much debate and speculation. Current research now points to the importance of cortisol and testosterone in the pathogenesis of cluster headaches, and they appear to be linked mechanistically to another hormone, melatonin. ⋯ Accumulated evidence suggests sympathetic dysfunction--embodied in the Horner sign so commonly seen in the cluster headache--as a necessary ingredient in the inception of the cluster headache. Sympathetic dysfunction now is thought to be associated with the hypercortisolism, hypotestosteronism, and lower-than-normal melatonin levels in the active cluster patient. Future research may hold the key to a fuller explanation of the complex interaction of hormonal systems in the cluster headache.

ReviewChronic widespread pain and psychiatric disorders in veterans of the first Gulf War.
More than 10% of the 700,000 American troops who served during the first Gulf War (GW) are receiving treatment for a constellation of diffuse and frequently poorly defined medical and psychiatric symptoms that have been designated the GW syndrome by both clinicians and the popular media. The current clinical consensus is that the symptoms reported in GW veterans are the sequela of combat and other stressful events that have been identified in the veterans of other wars and armed conflicts. ⋯ Research has confirmed a close bimodal relationship between chronic pain and psychiatric symptoms. Investigators are now exploring the efficacy of treatment approaches that address the close relationship between chronic pain and mental illness in this challenging patient population.

ReviewAre functional capacity evaluations affected by the patient's pain?
Functional capacity evaluations (FCE) are comprehensive batteries of performance-based tests used commonly to inform return-to-work decisions for injured workers. As many people undergoing FCE have painful musculoskeletal conditions limiting their work ability, pain becomes a critical factor in the assessment of function. This paper considers the available literature related to the influence of pain on FCE, which clearly indicates FCEs are behavioral assessments influenced by pain intensity and other pain-related constructs. ⋯ As such, for purposes of claims adjudication, FCE should not be considered a purely "objective" indicator of functional impairment independent of subject or evaluator perceptions. FCE may have some value for facilitating return-to-work or re-integrating chronically disabled workers into the workforce, although pain factors must be taken into consideration when making predictions about future work status. Shorter FCEs could potentially be as effective as more lengthy protocols.
