Similarly hypertension fact sheet purchase nifedipine 20 mg with visa, perceived control has been linked with coping efficacy in both pain and depression [30 blood pressure essential oils purchase generic nifedipine pills, 31] demi lovato heart attack order nifedipine with paypal. They dis- cuss an operant behavioral perspective (disorder results as a response to the environment), a more general behavioral perspective (pain becomes associated with displeasure in activities, activities are reduced to avoid pain, cycle of pain and depression results), and a cognitive perspective (disorder results from ‘systematic negative distortions in cognitive processes’). Research exploring the applications of these perspectives in the realm of the pain–depression rela- tionship, that is, targeting populations suffering from the comorbidity of chronic pain and depression, is lacking. Most of the emphasis on understand- ing applications of these theories has been in the depression literature, although the pain literature has become more active in this area recently. Summary Treatments such as the ones reviewed above have been shown to be effec- tive in treating both chronic pain and depression and researchers have begun identifying similar underlying mechanisms that may explain the joint effective- ness of these treatments. However, most research to date that has included mea- sures of both depression and chronic pain has investigated the effects of treatment for a particular population of chronic pain patients and measured changes in depression as well. It is less common for the selected sample to con- sist of patients with comorbid pain and depression, with the aim of under- standing effectiveness of treatments for this comorbid condition, or extending the sampling scheme to patients with extensive and complex internalizing comorbidities (e. Thus, while some of the work in this area has begun to explore the common mechanisms underlying the Krueger/Tackett/Markon 66 effects of treatment for pain and depression, it is important for future research to test theories of treatment for complex patterns of internalizing comorbidity that are frequently seen in clinical settings. Psychopharmacological Treatments That Work for Depression and Chronic Pain An influx of research over the last 15 years has provided compelling evi- dence that antidepressants can be used as an effective treatment for chronic pain. Tricyclics are a particular class of antidepressants that were hypothesized to be effective in treating pain. In support of this hypothesis, studies have gen- erally found that tricyclics ameliorate pain symptoms [33, 34] and are effective in treating both pain and depressive symptoms. Other antidepressants have also been studied in relation to pain, and some have been shown to have positive effects on pain symptoms [36–38] and on both pain and depressive symptoms [39, 40]. Hudson and Pope reviewed the evidence on effectiveness of antide- pressant treatments for a large class of disorders. Specifically, they identified major depressive disorder, bulimia, obsessive-compulsive disorder, panic disor- der, attention deficit/hyperactivity disorder, cataplexy, migraine, and irritable bowel syndrome as a related class of disorders based on studies showing effec- tive use of antidepressant treatments for them. Posttraumatic stress disorder and atypical facial pain nearly met the criteria to be classified in this grouping. Hudson and Pope termed this class of disorders that respond to antidepressants the ‘affective spectrum disorder’, based on the idea that response to treatment can be used to identify a similar pathophysiology among disorders. While most research in this area has looked at the impact of treatments for depression on symptoms of chronic pain, a recent study investigated the reverse relationship. Substance P, one of the best-understood neuropeptides, has been extensively studied in relation to pain. It has been widely established that sub- stance P antagonists are helpful in alleviating pain. Recently, evidence such as having similar patterns of distribution in the CNS, led one group of researchers to postulate that modulation of substance P may be linked to , or interact with, serotonin and norepinephrine pathways. A randomized, double-blind, placebo-controlled study demonstrated efficacy in the treatment Structural Models 67 of depressive symptoms with a substance P antagonist, supporting the theory that substance P plays a role in regulating depression as well as pain. Putative Mechanisms Underlying Psychopharmacological Treatments The documented high levels of comorbidity between depression and chronic pain have led some researchers to speculate that there is a common neurochemical association to account for the pain–depression relationship. Specifically, researchers have pointed to serotonin and norepinephrine to explain this connection. It has been well-established in the literature that serotonin and norepinephrine play a role in depression [46, 47], and in the expe- rience of pain.

Is there a way to prevent or mitigate subsequent postwar symptoms and associated depression and disability? We 1The views expressed in this article are those of the authors and do not necessarily represent the official policy or position of the Uniformed Services University of the Health Sciences, Walter Reed Army Medical Center, Department of the Army, Department of Defense, or the US Government. This article delineates the model, describes its epidemi- ological foundations, and details examples of how it is being adopted and improved as part of the system of care for US military personnel, war veterans and families. A scientific test of the model’s overall effectiveness is difficult, yet healthcare systems for combatants and their families are already being put to pragmatic tests as troops return from war in Iraq and Afghanistan and from other military challenges. Karger AG, Basel Introduction In 1991, the United States military moved nearly 700,000 personnel to the Gulf War theater of operations over a 6-month period and with the help of a multinational coalition force rapidly extricated Iraq from Kuwait. In the process, only 147 US troops were killed in action, and the rates of disease and nonbattle injuries among these troops were similarly low. Today, however, over 1 in 7 US veterans of the war has sought government-sponsored health- care for related health concerns. Fully 17% of UK Gulf War veterans describe themselves as suffering from the ‘Gulf War syndrome’, a set of poorly defined and heterogeneous ailments consisting mainly of chronic pain, fatigue, depression and other idiopathic symptoms. Nearly 30% of US Gulf War veterans have sought service-connected disability benefits and nearly 87% of processed claims have resulted in benefits, including some 3,200 of the more than 11,000 claims for a heterogeneous set of ‘undiagnosed illnesses’ that usually involve some combination of chronic pain, fatigue, and depression. More than 250 million dollars spent on US government-funded medical research has failed to identify any consistent elevations in disease-related mor- tality or hospitalization rates among these veterans. Epidemiological studies have consistently shown an excess of nearly every reportable symptom among Gulf War veterans compared to nondeployed military personnel from the Gulf War era, but these symptoms have failed to lead investigators to the identi- fication of any single responsible disease or illness. The inconclusive debate regarding potential causes of pain, depression, and other idiopathic symptoms among the veterans has been fierce and confusing while implicating widely divergent factors from oil well smoke, potentially contagious infections and chemical and biological warfare agents to major depression, posttraumatic stress disorder and somatization [7, 8]. These syndromes have followed virtually every war dating back at least as far as the Crimean War of the 1850s and have gone by a variety of different names (e. In each case, the causes of these postwar syndromes have remained elusive, but polarized etiological debates focused on competing psychological vulnerability versus biomedical disease explanations. In these postwar debates, various stakeholder groups have frequently taken up predictable and at times self-interested positions, waging well-publicized battles over the legitimacy of putative exposures and potentially related postwar symptom syndromes. These etiological contests and their associated scientific, political, legal, and media debates may have unintended public health consequences including social divisions, unwarranted community health worries, and elevated mistrust between conflict veterans and the healthcare systems and individual providers that are charged with meeting their postwar health needs. These debates and the distress resulting from them may also alter potentially important health behaviors such as care-seeking, compliance with medical advice, and alcohol and tobacco use, and these behaviors can compound usual medical and psychosocial sources of symptoms and disability. In these and other ways, each war sets into motion an expanding legacy of chronic physical, emotional, and fiscal consequences that ultimately affect not only veterans but the larger society as well. Prevailing disease management approaches to prevention and healthcare delivery do not adequately address the symptoms and disability that occur among war veterans in the weeks, months, and years following wartime envi- ronmental and psychosocial exposures. There is, therefore, a critical need for innovative and comprehensive models that can better address postwar pain, fatigue, depression, and other idiopathic symptoms. This need is particularly poignant given the recent return of US and UK military forces to Iraq and the mission to remain there during the postwar period. Can we prevent what may become the latest in the long line of postwar syndromes or are we destined for a second version of the ‘Gulf War syndrome’?
