    The aim of this study was to review published controlled trials of hypnotic treatments for chronic and cancer procedure-related pain in children. Trials were included if participants were 18 years of age or below, were randomized and had populations with chronic pain or cancer procedure-related pain. After the studies were assessed, 12 were selected for review. Although the evidence is limited, the findings indicate that hypnosis is an effective pain-control technique when used with children suffering from cancer procedure-related pain or chronic pain. Further research into the use of hypnosis to manage chronic pain in children should be a priority so that empirically based conclusions can be drawn about the effects of hypnosis on children.

    Postoperative pain and analgesic requirements may be associated with chronic pain. The aim of the study was to investigate this association. We studied 98 patients who had cancer breast surgery and served as controls in four previous studies, receiving placebo. We compared the pain and analgesic requirements 0-9 h and 1-6 days postoperatively: a) between patients with chronic pain 3 months postoperatively versus patients without and b) between those patients who consumed analgesics at home versus those who did not. Patients with chronic pain had experienced higher intensity pain at rest the first 9 postoperative hours (VAS-rest p = 0.033). Patients requiring analgesics at home had consumed postoperatively more opioids (p = 0.005) and more paracetamol (p = 0.037). These patients had experienced pain of higher intensity the first 9 postoperative hours (VAS-rest p = 0.022, VAS-movement p = 0.009) as well as during the six postoperative days (VAS-rest p = 0.013, VAS-movement p = 0.001). Higher intensities of acute postoperative pain are associated with chronic pain development. Higher analgesic needs and higher acute postoperatively pain intensity are associated with long-term analgesic consumption. PMID:19235522

    Effective therapeutic options for patients living with chronic pain are limited. The pain relieving effect of cannabinoids remains unclear. A systematic review of randomized controlled trials (RCTs) examining cannabinoids in the treatment of chronic non-cancer pain was conducted according to the PRISMA statement update on the QUORUM guidelines for reporting systematic reviews that evaluate health care interventions. Cannabinoids studied included smoked cannabis, oromucosal extracts of cannabis based medicine, nabilone, dronabinol and a novel THC analogue. Chronic non-cancer pain conditions included neuropathic pain, fibromyalgia, rheumatoid arthritis, and mixed chronic pain. Overall the quality of trials was excellent. Fifteen of the eighteen trials that met the inclusion criteria demonstrated a significant analgesic effect of cannabinoid as compared with placebo and several reported significant improvements in sleep. There were no serious adverse effects. Adverse effects most commonly reported were generally well tolerated, mild to moderate in severity and led to withdrawal from the studies in only a few cases. Overall there is evidence that cannabinoids are safe and modestly effective in neuropathic pain with preliminary evidence of efficacy in fibromyalgia and rheumatoid arthritis. The context of the need for additional treatments for chronic pain is reviewed. Further large studies of longer duration examining specific cannabinoids in homogeneous populations are required.

    Background and aim Ketamine is a drug used for the induction and maintenance of general anesthesia, for the treatment of postoperative and posttraumatic acute pain, and more recently, for the reduction of postoperative opioid requirements. The main mechanism of action of ketamine is the antagonization of N-methyl-D-aspartate (NMDA) receptors that are associated with central sensitization. In the pathogenesis of chronic pain and particularly in neuropathic pain, an important role is played by the activation of NMDA receptors. Although ketamine is indicated and used for the treatment of chronic cancer pain as an adjuvant to opioids, there are few clinical studies that clearly demonstrate the effectiveness of ketamine in this type of pain. The aim of this study is to analyze evidence-based clinical data on the effectiveness and safety of ketamine administration in the treatment of chronic neoplastic pain, and to summarize the evidence-based recommendations for the use of ketamine in the treatment of chronic cancer pain. Method We reviewed the literature from the electronic databases of MEDLINE, COCHRANE, PUBMED, MEDSCAPE (1998–2014), as well as chapters of specialized books (palliative care, pain management, anesthesia). Results A number of studies support the effectiveness of ketamine in the treatment of chronic cancer pain, one study does not evidence clear clinical benefits for the use of ketamine, and some studies included too few patients to be conclusive. Conclusions Ketamine represents an option for neoplasic pain that no longer responds to conventional opioid treatment, but this drug should be used with caution, and the development of potential side effects should be carefully monitored.

  16. Using opioids in general practice for chronic non-cancer pain: an overview of current evidence.

    PubMed

    Currow, David C; Phillips, Jane; Clark, Katherine

    2016-05-01

    Chronic non-cancer pain (lasting more than 3 months) is highly prevalent in Australia (17% of males and 20% of females) and its optimal management is crucial to the health and wellbeing of the community. For 5% of the population, such pain interferes markedly with daily function. Part of the treatment for acute non-cancer pain for many people will include opioid analgesics at least for days to weeks. However, as pain becomes chronic, evidence to support ongoing prescription of opioids is lacking. There is increasing pressure to ensure that prescribing opioid analgesics is minimised to reduce not only the risk of dependence and illicit diversion but also the potential harms associated with tolerance, side effects and complications. Frameworks for considering opioid prescribing include assessing suitability of the patient for opioids; initiating a trial of therapy; and monitoring long term use. There is limited evidence of the long term efficacy of opioids for chronic non-cancer pain, and documented clinical consequences beyond addiction include acceleration of loss of bone mineral density, hypogonadism and an association with increased risk of acute myocardial infarction. Careful clinical selection of patients can help optimise the evidence-based use of opioids for chronic non-cancer pain: only treat pain that has been as well defined as possible when non-opioid therapies have not been effective; consider referral to specialist services for assessment if doses are above 100 mg oral morphine equivalent per 24 hours or the duration of therapy is longer than 4 weeks; limit prescribing to only one practitioner; seek an agreement with the patient for the initiation and potential withdrawal of opioids if the therapeutic trial is not effective.

    Testis cancer is a disease that directly affects a man's sense of masculinity and involves treatments compromising sexual function. The aim of this study was to investigate the prevalence of sexual dysfunction and the influence of chronic pain on sexuality in long-term testis cancer survivors. Thus, we examined 539 patients after they had one testis removed because of a testicular germ cell tumor. Having completed oncologic therapy, all patients received a detailed questionnaire asking about the occurrence and clinical presentation of testis pain before and after orchiectomy. In addition, items from the abridged International Index of Erectile Function and Brief Sexual Function Inventory were used to gain precise information on individual sexual function. Overall, 34.5% of our testicular cancer survivors complained of reduced sexual desire, and sexual activity was reduced in 41.6%. Erectile dysfunction was present in up to 31.5% of patients. In 24.4%, the ability to maintain an erection during intercourse was impaired. Ejaculatory disorders (premature, delayed, retrograde, or anejaculation) occurred in 84.9% of our testis cancer survivors. A total of 32.4% of our participants experienced a reduced intensity of orgasm, and 95.4% experienced reduced overall sexual satisfaction. There was a significant correlation between the occurrence of chronic pain symptoms and the relative frequency and intensity of erectile dysfunction, inability to maintain an erection, ejaculation disorders, and reduced intensity of orgasm. In conclusion, chronic pain has a negative impact on sexuality in testis cancer survivors. PMID:21474790

    Neurosurgical treatment of pain is based on 3 concepts: 1) lesional techniques interrupt the transmission of nociceptive neural input by lesionning the nociceptive pathways (cordotomy, radicotomy...), they are indicated to treat morphine-resistant cancer pain; 2) neuromodulation techniques try to decrease pain by reinforcing inhibitory mechanisms, using chronic electrical stimulation of the nervous system (peripheral nerve stimulation, spinal cord stimulation, motor cortex stimulation...) to treat chronic neuropathic pain; 3) intrathecal infusion of analgesics (morphine, ziconotide), using implantable pumps, allows to increase their efficacy and to reduce their side effects. These techniques can improve, sometimes dramatically, patients with severe and chronic pain, refractory to all other treatments. PMID:23923757

    Little is known about patients prescribed high doses of opioids to treat chronic non-cancer pain, though these patients may be at higher risk for medication-related complications. We describe the prevalence of high-dose opioid use and associated demographic and clinical characteristics among veterans treated in a VA regional healthcare network. Veterans with chronic non-cancer pain prescribed high doses of opioids (>=180 mg/day morphine equivalent; n=478) for 90+ consecutive days were compared to two groups with chronic pain: Traditional-dose (5–179 mg/day; n=500) or no opioid (n=500). High-dose opioid use occurred in 2.4% of all chronic pain patients and in 3.4% of all chronic pain patients prescribed opioids long-term. The average dose in the high-dose group was 324.9 (SD=285.1) mg/day. The only significant demographic difference among groups was race (p=0.03) with black veterans less likely to receive high doses. High-dose patients were more likely to have four or more pain diagnoses and the highest rates of medical, psychiatric, and substance use disorders. After controlling for demographic factors and VA facility, neuropathy, low back pain, and nicotine dependence diagnoses were associated with increased likelihood of high-dose prescriptions. High-dose patients frequently did not receive care consistent with treatment guidelines: there was frequent use of short-acting opioids, urine drug screens were administered to only 40.8% of patients in the prior year, and 32.0% received concurrent benzodiazepine prescriptions, which may increase risk for overdose and death. Further study is needed to identify better predictors of high-dose usage, as well as the efficacy and safety of such dosing. PMID:20801580

    Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed. PMID:24799477

    Abstract Breast cancer surgery is known to cause severe acute postoperative pain, which can persist for a long time. We administered nefopam preventively to patients undergoing lumpectomy with axillary lymph node dissection or sentinel lymph node biopsy, and evaluated its efficacy on acute and chronic postoperative pain. Enrolled patients were assigned to the nefopam (n = 41) or the control (n = 42) group. Before initiating the operation, 20 mg of nefopam was given to the patients of the nefopam group, and normal saline was used in the control group. Ketorolac was given at the end of surgery, and meloxicam was prescribed in the postoperative period to all patients in both groups. Pain was assessed using a numerical rating scale (NRS), and the rescue analgesic drug was given when the NRS was >5. Implementation of postoperative chemotherapy, radiotherapy (RT), or hormone therapy was evaluated. The NRS of postoperative pain was significantly lower in the nefopam than in the control group in the postanesthetic care unit (4.5 ± 2.2 vs 5.7 ± 1.5, respectively; P = 0.01), at postoperative 6 h (3.0 ± 1.6 vs 4.5 ± 1.3, respectively; P < 0.001), and at postoperative 24 h (3.1 ± 1.1 vs 3.8 ± 1.5, respectively; P = 0.01) with reduced use of rescue analgesic drugs. Significantly fewer patients suffered from chronic postoperative pain in the nefopam than in the control group at postoperative 3 months (36.6% vs 59.5%, P = 0.04). Considering only the cohort without postoperative adjuvant RT, the difference in the proportion of patients reporting chronic pain increased (23.5% in the nefopam group vs 61.5% in the control group, P = 0.04). Preventive nefopam was helpful in reducing the acute postoperative pain, with reduced use of rescue analgesic drugs, and it contributed to reduced occurrence of chronic pain at postoperative 3 months after breast cancer surgery.

    Neurosurgical treatment of pain used two kind of techniques: 1) Lesional techniques interrupt the transmission of nociceptive neural input by lesionning the nociceptive pathways (drezotomy, cordotomy, tractotomy…). They are indicated to treat morphine-resistant cancer pain and few cases of selected neuropathic pain. 2) Neuromodulation techniques try to decrease pain by reinforcing inhibitory and/or to limit activatory mechanisms. Chronic electrical stimulation of the nervous system (peripheral nerve stimulation, spinal cord stimulation, motor cortex stimulation…) is used to treat chronic neuropathic pain. Intrathecal infusion of analgesics (morphine, ziconotide…), using implantable pumps, allows to increase their efficacy and to reduce their side effects. These techniques can improve, sometimes dramatically, selected patients with severe and chronic pain, refractory to all other treatments. The quality of the analgesic outcome depends on the relevance of the indications. PMID:25681114

    The perception and interpretation of pain is the end point of an interaction of cognitive, cultural, and environmental factors and this complex interaction effects the pain response and quality of life of each person which shows that pain perception and the verbal and behavioral response shows variations and is specific for each patient. Chronic pain can be due to Fibromyalgia Syndrome (FMS) and Neuropathic Pain (NP) where the underlying pathophysiologic mechanisms are being revealed or it can be chronic low back pain (CLBP) where pain persists in spite of healing of tissue and no underlying pathologic mechanism can be defected. Central sensitization, inhibition of descending pain inhibitory systems, functional changes in autonomic nervous system amd neurotransmitter as well as changes in stress response system are factors contributing to the initiation and maintenance of pain and cognitive, behavioral factors are also important contributors in chronic pain. Biopsychosocial and biomedical mechanisms should be assessed in the rehabilitation interventions. The aims of rehabilitation in chronic pain are to increase activity tolerance, functional capacity and to decrease socio-economic loads. The targets of activity should be physical, functional and social. Psychologic based programs as cognitive-behavioral techniques and operant conditioning are also valid procedures in rehabilitation of chronic pain patients. Rehabilitation should be multidisciplinary and of long-term targeted to valid out-come for success. PMID:15977088

    Rising mortality rates, increased opioid prescription abuse, and a perceived need to provide practitioners with structured guidance in opioid prescribing have prompted the Washington State Legislature to establish new legal standards of practice regarding chronic non-cancer pain management. Clinicians are required to conduct a detailed physical examination and health history prior to treatment. Risk assessments for abuse and detailed periodic reviews of treatment are required at least every 6 months. Those considered "high risk" or who have significant psychiatric comorbidities will be required to sign and follow a written agreement or pain contract, obtain their pain prescriptions from a single provider, and submit to biological drug screening. Unless an exemption exists, patients prescribed > 120 mg of morphine-equivalents daily, considered severe pain nonresponders, necessitating dosage escalation, diagnosed with multifaceted mental health-related comorbidities, demonstrating diagnostic ambiguity, and/or requiring significant treatment individualization are referred to a pain specialist. Episodic care settings should refrain from supplying opioids to chronic pain patients whenever possible. The ER is for Emergencies coalition instituted the Seven Best Practices program throughout the state to reduce unnecessary visits, coordinate prescribing practice, reduce Medicaid expenditures, and improve overall patient care. The state reported approximately $33.65 million in savings in 2013 through the use of these practices and converting Medicaid participants from fee-for-service to managed care plans. Similar legislation to complement clinical practice guidelines is expected to be enacted in other states. It is vital that practitioners comprehend the new guidelines and make appropriate adjustments in their opioid prescribing habits. PMID:26369588

    PubMed

    Sunshine, A; Olson, N Z

    1988-12-01

    This article summarizes the results of five single-dose clinical studies of three pain models: postpartum, postoperative, and chronic cancer pain. The efficacy of ketoprofen (in varying doses from 25 to 225 mg) was compared with one of the following standards: aspirin (650 mg), codeine (90 mg), acetaminophen (650 mg) plus codeine (60 mg), and parenteral morphine (5 mg and 10 mg). The results indicate that ketoprofen in doses as low as 25 mg has analgesic properties significantly superior to those of placebo. For the treatment of postpartum pain, ketoprofen was significantly more effective than aspirin 650 mg but not significantly different from codeine 90 mg. Ketoprofen doses of 50 mg and 150 mg also provided analgesia superior to that with acetaminophen 650 mg plus codeine 60 mg for the management of moderate to severe postoperative pain. Moreover, oral doses of ketoprofen (75 and 225 mg) provided analgesia similar to that obtained with 5 and 10 mg parenteral doses of morphine. Adverse effects related to ketoprofen were relatively minor and infrequent. Ketoprofen was recently approved for use as an analgesic for treatment of mild to moderate pain in total daily doses up to 300 mg; the recommended initial dose is 25 to 50 mg every 6 to 8 hours as necessary.

    Poor efficiency in terms of treatment of unspecific back pain and related chronic pain syndromes has led to the necessity of general care guidelines addressing evidence-based strategies for treatment of lower back pain (LBP). Systematically validated and reviewed algorithms have been established for all kinds of unspecific back pain, covering both acute and chronic syndromes. Concerning the impact of psychosocial risk factors in the development of chronic LBP, multimodal treatment is preferred to monomodal strategies. Self-responsible acting on the part of the patient should be supported while invasive methods in particular, i.e. operative treatment, should be avoided due to lacking evidence in outcome efficiency.

    Controversy surrounds the use of strong opioid analgesic drugs for chronic non-cancer pain. Specialists have concluded that fears of problematic drug use are often unfounded. In contrast, others claim the existence of significant problems.'Problematic drug use' includes the following definitions; addiction, abuse, physiological dependence and tolerance.We present a case study and the results of a pilot, longitudinal, cohort study, via a pilot questionnaire, of 22 chronic pain clinic patients following a trial of opioid drugs. The results suggest that chronic non-cancer pain patients can be maintained on opioids with few problems, and likewise can withdraw with minimal adverse effects, other than a return of pain.

    Nonpharmacologic therapies have become a vital part of managing chronic pain (CP). Although these can be used as stand-alone therapies, nonpharmacologic treatments often are used to augment and complement pharmacologic treatments (ie, multimodal therapy). Nonpharmacologic approaches can be classified as behavioral, cognitive, integrative, and physical therapies. Core principles in developing a treatment plan are explaining the nature of the CP condition, setting appropriate goals, and developing a comprehensive treatment approach and plan for adherence. Clinicians should become familiar with these interventions so that they can offer patients flexibility in the pain management approach. Effective noninvasive treatment modalities for CP include behavioral therapy for short-term pain relief; cognitive behavioral therapy for reducing long-term pain and disability; hypnosis as adjunctive therapy; guided imagery, diaphragmatic breathing, and muscle relaxation, especially for cancer-related pain; mindfulness-based stress reduction for patients with chronic low back pain; acupuncture for multiple pain conditions; combination manipulation, manual therapy, endurance exercise, stretching, and strengthening for chronic neck pain; animal-assisted therapy; and S-adenosyl-L-methionine for joint pain. Guidelines for use of these treatment modalities are based on expert panel recommendations in combination with data from randomized controlled trials. PMID:25970869

A recognition of the importance of treating pain has influenced this increase, but higher rates of opioid prescribing have produced undesirable outcomes including the misuse of medication as well as an increased number of deaths and emergency department visits attributable to opioids. Diverse psychiatric disorders, such as major depression, now also occur in 40% of those with an opioid use disorder (OUD). Neuroscience We now understand that addictive behaviors are caused by both environmental and genetic factors. Although OUD has historically been perceived as a weakness of character, it is now clear that it is a chronic disease, which results from a complex interaction between a substance, such as opioid, environmental factors, and an individual's genotype. Unfortunately, this evidence has yet to be successfully translated into clinical practice and most physicians are unable to diagnose and manage OUD patients appropriately.Clinical guidelines Many clinical guidelines for the management of chronic, non-cancer pain are available. All guidelines identify the need to assess the patient appropriately and screen for factors associated with misuse before prescribing opioids. Guidelines generally acknowledge that patients should not be denied appropriate pain management, but that some patients will require close supervision and frequent follow-up to prevent the misuse of prescription opioids.

    Background: In both developing and developed countries, chronic pain remains a real issue and a true disease that affects up to 42% of the population in some areas. Opioids are widely used for the management of chronic pain with variations in prescribing practices, indications and observed efficacy. Aim: to analyze trends in opioids prescribing and patient response in chronic non-cancer pain conditions. Methods: Retrospective study of 1500 casenotes of patients suffering variable non-cancer chronic pain conditions. Detailed review of those cases who were managed using opioids. Statistical analysis using “SOFA” software set. Results: The prevalence of opioids prescribing in patients suffering this condition was thus around 35% (n=526). Women older than 50 years were more likely than men to have a chronic pain condition and to be given opioid therapy for 1 year or more. Opioid efficacy on neuropathic and mixed types of pain was found to be significant with relatively low rate of drop-out and limited side-effects that are not life threatening. Overall, patients stopped or changed their opioid medication due to inefficacy in only 12.7% of cases. Conclusions: The simple fact of having pain is itself a source of self-reported disability regardless of the actual physiological or pathological mechanism. Policy makers should be aware of the huge impact of chronic pain disease and of its serious effects on social and economical well-being. In developing countries, chronic pain could represent a real challenge for all parties. Multimodal management, including opioids, appears crucial for the approach of this disease. PMID:24015132

    Despite progress in pain management, chronic non-cancer pain (CNCP) represents still a clinical challenge. The efficacy and safety profile of tramadol make it suitable as a long-term treatment in a variety of CNCP conditions. New once-daily (OD) formulations of tramadol have been marketed in various countries, in order to offer the advantage of a reduced dosing regimen and to improve patients’ compliance. This review focuses on the technology, pharmacology, clinical efficacy, and safety of different once-daily tramadol formulations. Hydrophilic vs hydrophobic matrix systems and newer technologies used in once-daily formulations to control drug delivery are discussed. Three randomized controlled trials (RCTs) established OD tramadol analgesic efficacy to be superior to that of placebo for pain management and functional improvement in patients with osteoarthritis. Three RCTs demonstrated similar rates of efficacy between OD tramadol and immediate-release (IR) or sustained-release (SR) formulations, with a better adverse events profile. An open trial on long term tolerability showed that OD tramadol is generally safe in rheumatological pain treatment. PMID:18473006

    This paper examines how a group of working class people describes and experiences chronic pain. This hermeneutical-phenomenological study concentrates on the lived body of pain from three perspectives, drawing on interviews with 14 people who were attending a pain management program. First I consider the terms in which pain is circumscribed in the narratives, stories told in the context of learning to manage pain. These terms are polarities, ways of specifying and legitimating pain in relation to "mind" and "body." Pain, in the discursive polarities that define it, is the private property of an individual, who must in some fashion prove that pain exists in an objective manner. The speaker, in this discourse, stands as the one responsible for the production of pain. In the second part, the analysis turns to what this discourse reveals about pain as a lived body phenomenon. Here the analysis centers upon the torment of having to inhabit the intolerable, upon how pain unmakes the lifeworld of the sufferer, and how, simultaneously, people make pain. The place of pain is the body, as body-in-place. The place of pain is at the boundaries of human dwelling, a kind of non-place, expressed metaphorically as "prison" or "homelessness." Finally, after these considerations of how pain is described, in part three, I turn to the act of "saying" pain, that is, to the narratives as addressed to someone else. The participants were not simply dispensing information; they were saying something to me. The narratives had the form of complaints. The form of the narratives, in the context of the pain program, was a quasi-legal call to rectify wrongs. PMID:10574237

    A multidisciplinary pain centre study of 120 consecutive chronic orofacial pain patients assessed pain description and intensity ratings, gender differences, prevalence of concurrent conditions, and interinstrument relationships of the McGill Pain Questionnaire and visual analogue scale. Pain words chosen by patients to describe conditions were predominantly sensory words, and patients with concurrent conditions often listed words indicating a substantial affective component. Results showed pain intensity ratings of chronic orofacial pain conditions have similar or higher pain ratings when compared with other medical chronic pain conditions such as back pain, cancer pain and arthritis. There was a significantly higher female: male ratio (88:32) with gender playing an important but poorly understood causal role. The most frequent condition diagnosed was atypical facial pain (n = 40), followed by temporomandibular disorder (n = 32), atypical odontalgia (n = 29) and pathology of the orofacial region (n = 19). Temporomandibular disorder was present in 75 of the 120 subjects, as the sole pain complaint (n = 32) or as an associated secondary condition (n = 43), indicating concurrent pain conditions exist and may be related. There were significantly higher total pain scores of the McGill Pain Questionnaire in patients with multiple conditions compared with patients with a single condition. The visual analogue scale showed a significant correlation to the number of words chosen index of the McGill Pain Questionnaire for orofacial pain. PMID:9973710

    Introduction Chronic pain is a public health problem of epidemic proportion in most countries with important physical, psychological, social and economic consequences. The management of chronic pain is complex and requires an integrated network approach between all levels of the healthcare system and the involvement of several health professionals from different disciplines. Measuring the performance of organisations that provide care to individuals with chronic pain is essential to improve quality of care and requires the use of relevant performance and quality indicators. A scoping review methodology will be used to synthesise the evidence on performance and quality indicators developed for non-cancer chronic pain management across the continuum of care. Methods and analysis The following electronic databases will be searched from 2000 onwards: Cochrane Effective Practice and Organisation of Care (EPOC) Review Group Specialised Register; Cochrane Library; EMBASE; PubMed; CINAHL; PsycINFO; ProQuest Dissertations and Theses. All types of studies will be included if these are concerned with performance or quality indicators in adults with chronic non-cancer pain. In addition, searches will be conducted on provincial, national and international health organisations as well as health professional and scientific associations’ websites. A qualitative descriptive approach will be used to describe characteristics of each indicator. All identified indicators will be classified according to dimensions covered by Donabedian and the Triple Aim frameworks. Ethics and dissemination The scoping review findings will inform the development of a performance measurement system comprising a list of performance indicators with their level of evidence which can be used by stakeholders to evaluate the quality of care for individuals with chronic non-cancer pain at the patient, institutional and system level. The results will be disseminated via several knowledge translation strategies

    Chronic pain may recur after initial response to strong opioids in both patients with cancer and patients without cancer or therapy may be complicated by intolerable side effects. When minimally invasive interventional pain management techniques also fail to provide satisfactory pain relief, continuous intrathecal analgesic administration may be considered. Only 3 products have been officially approved for long-term intrathecal administration: morphine, baclofen, and ziconotide. The efficacy of intrathecal ziconotide for the management of patients with severe chronic refractory noncancer pain was illustrated in 3 placebo-controlled trials. A randomized study showed this treatment option to be effective over a short follow-up period for patients with pain due to cancer or AIDS. The efficacy of intrathecal opioid administration for the management of chronic noncancer pain is mainly derived from prospective and retrospective noncontrolled trials. The effect of intrathecal morphine administration in patients with pain due to cancer was compared with oral or transdermal treatment in a randomized controlled trial, which found better pain control and fewer side effects with intrathecal opioids. Other evidence is derived from cohort studies. Side effects of chronic intrathecal therapy may either be technical (catheter or pump malfunction) or biological (infection). The most troublesome complication is, however, the possibility of granuloma formation at the catheter tip that may induce neurological damage. Given limited studies, the evidence for intrathecal drug administration in patients suffering from cancer-related pain is more compelling than that of chronic noncancer pain. PMID:24118774

    Summary points 1. Musculoskeletal problems are the commonest reason for medical discharge in all the British armed forces. By definition, these problems are chronic and resistant to treatment. 2. Pain is also common in veterans who have experienced severe injuries (polytrauma), often accompanied by post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) orpostconcussive syndrome. 3. In veterans seeking treatment for chronic pain, PTSD is common. There is also evidence for elevated levels of alcohol misuse in veterans who have been deployed to conflict. However, most veterans do not have pain, PTSD or alcohol problems. 4. Pain clinicians would benefit from training in meeting veterans’ needs, in order to promote their engagement and successful treatment. This should include countering stereotypes, information about the military and support for the assessment and onward referral of PTSD and alcohol problems. PMID:26516504

    There has been a recent increase in public and professional concern about the prescription of strong prescription opioids for pain. Despite this concern, research to date has been limited because of a number of factors such as small sample sizes, exclusion of people with complex comorbidities, and studies of short duration. The Pain and Opioids IN Treatment is a 2-year prospective cohort study of 1500 people prescribed with pharmaceutical opioids for their chronic pain. This article provides an overview of the demographic and clinical characteristics of the cohort using the baseline data of 1514 community-based people across Australia. Participants had been in pain for a period of 10 years and had been on prescription opioids for approximately 4 years. One in 10 was on a daily morphine equivalent dose of ≥200 mg. Employment and income levels were low, and two-thirds of the sample reported that their pain had impacted on their employment status. Approximately 50% screened positive for current moderate-to-severe depression, and 1 in 5 had made a lifetime suicide attempt. There were a number of age-related differences. The younger groups experienced higher levels of pain and pain interference, more mental health and substance use issues, and barriers to treatment, compared with the older group. This study found that the people who have been prescribed strong opioids for chronic pain have very complex demographic and clinical profiles. Major age-related differences in the experiences of pain, coping, mental health, and substance use suggest the necessity of differential approaches to treatment. PMID:25599444

    Acute and chronic orofacial pain continues to be poorly understood and managed. The National Health and Medical Research Council of Australia (NHMRC) 1999 report on acute pain management promotes the development of evidence based clinical practice guidelines aimed at improving both the quality of health care and health outcomes in medical and dental practice in Australia. Nerve signals arising from sites of tissue or nerve injury lead to long term changes in the central nervous system and the amplification and persistence of pain. These nociceptor activity-induced neuronal changes known as central sensitization, have important clinical implications in the development of new approaches to the management of persistent pain. These findings and implications are discussed in relationship to poorly managed and understood conditions such as oral dysaesthesia, burning mouth syndrome, atypical facial pain/atypical odontalgia, peripheral nerve injury, deafferentation and phantom tooth syndrome.

    We evaluated the effect of multimodal analgesia on acute and chronic pain after breast surgery for cancer. Fifty patients scheduled for breast cancer surgery were blindly randomized to receive gabapentin, eutectic mixture of local anesthetics cream, and ropivacaine in the wound or three placebos. Pain (visual analog scale) and analgesics were recorded in the postanesthesia care unit (PACU) 3, 6, and 9 h and 8 days after surgery. Three and 6 mo later, patients were assessed for chronic pain. The treatment group consumed less paracetamol in the PACU (469 versus 991 mg; P < 0.002) and less Lonalgal (1.0 versus 4.4 tablets; P = 0.003) than the controls, exhibited lower visual analog scale scores at rest in the PACU (P = 0.001) and on postoperative Days 1, 3, and 5 (P = 0.040, P = 0.015, and P = 0.045, respectively), and after movement in the PACU (P = 0.001) and on postoperative Days 2, 4, and 8 (P = 0.028, P = 0.007, and P = 0.032, respectively). Three and 6 mo after surgery, 18 of 22 (82%) and 12 of 21 (57%) of the controls reported chronic pain versus 10 of 22 (45%) and 6 of 20 (30%) in the treatment group (P = 0.028 and P = 0.424, respectively); 5 of 22 and 4 of 21 of the controls required analgesics versus 0 of 22 and 0 of 20 of those treated (P = 0.048 and P = 0.107, respectively). Multimodal analgesia reduced acute and chronic pain after breast surgery for cancer. PMID:16244006

A summary of various medication classes and anesthetic techniques is provided that highlights evidence emerging from neurosurgical literature. This summary covers opioid management, acetaminophen, nonsteroidal antiinflammatories, ketamine, lidocaine, dexmedetomidine, corticosteroids, gabapentin, and regional anesthesia for neurosurgery. At present, there is not enough investigation into these areas to describe best practices for treating or preventing chronic pain in neurosurgery; but providers can identify a wider range of options available to personalize perioperative care strategies.

    Chronic non-cancer pain (CNCP) is significant global health issue, accounting for a substantial increase in prescription analgesics worldwide, in recent decades. This clinical burden is evident in the UK prison population, where the prevalence of CNCP has never previously been determined. This study, conducted in June/July 2013, used prescribing data and a systematic review of clinical records from two UK prison establishments to derive a figure for point-prevalence of CNCP. Results showed that 20% of the total aggregated prisoner rolls (N = 1944) described CNCP and had been in receipt of treatment with daily analgesia, for a period of at least 3 months prior to observation date. This prevalence of CNCP was related to increasing age group (Spearman's rank correlation 0.94). Of those on continuous analgesic therapy (CAT), 44% were taking continuous opioid therapy (COT) of any sort. Prisoners with a diagnosis of opioid-type drug dependence (OTDD) were more than twice as likely to complain of CNCP and be on continuous medication for it (odds ratio 2.3). The issues relating to CNCP in prisons are discussed. Further research is recommended, identifying factors influencing CNCP prevalence in prisons, and enabling comparisons to CNCP prevalence in the UK general population. PMID:26516564

    Objective We sought to identify primary care providers’ interest in, as well as perceived barriers and facilitators to, using novel telemedicine technologies (e.g., smartphones) for managing chronic non-cancer pain (CNCP) in older adults. Design Six focus groups were conducted with 25 primary care providers. Setting Two academically affiliated primary care practices serving older adults with CNCP in New York City. Methods The investigators used content analysis to analyze transcribed focus group data and identify specific themes. Results While most providers reported limited use of telemedicine, they expressed substantial interest in trying devices such as smartphones in the management of older patients with CNCP. Perceived barriers to implementation of telemedicine tools included information overload, lack of mobile device usability among patients and clinicians, liability issues, and cost. To overcome these barriers, participants suggested implementing electronic or human-based pre-analysis of data (e.g., a computer or a person that triages patient data), creating a low-cost and user-friendly mobile device design, and targeting appropriate user populations. Conclusions Primary care providers are interested in applying telemedicine when caring for older adults with CNCP. Although they perceived multiple barriers to device implementation, they offered innovative solutions to address these barriers. Providers felt that novel telemedicine technologies may improve the management of CNCP but wanted evidence that the devices were both cost- and time-efficient, and led to improved patient outcomes before adopting their use in practice.

    Several animal studies have demonstrated that pain is modulated by spinal mechanisms involving prostaglandins and that acetylsalicylic acid (ASA) administered intrathecally has an analgesic effect. We report our experience of this treatment in 60 patients with proven and advanced cancer. An isobaric solution of lysine acetylsalicylate was administered by lumbar puncture in doses ranging from 120 to 720 mg of ASA. The results were evaluated using the habitual criteria: scoring system, behaviour, consumption of analgesic drugs. In this trial the method proved astonishingly effective (78% of the cases). Analgesia was strong, almost immediate and without influence on motricity. No thermic or neurovegetative changes were noted. The effect of one injection lasted from 3 weeks to 1 month on average; it was reproduced and often more prolonged after a repeat injection. Pain associated with bone metastases seems to constitute the best indication, notably in breast and lung cancer and in myeloma. Visceral (pancreas) or neural pain requires higher doses to respond. Failures (22%) were due to such factors as insufficient dosage at the very beginning of our experience or severe depressive syndrome. The perineal and sphincteral pain of rectal cancer often resists treatment. This simple, inexpensive and very effective method with no other complication than a frequent tendency to fatigue should rank among other analgesic measures in cancer. The lack of respiratory depression is a major advantage over catheter spinal opiate analgesia. We consider that its main indications are pain associated with osteolytic metastases of adenocarcinomas, and myelomas. Owing to the absence of formal toxicological data, its use must be limited to cancer pain and to patients with a life expectancy of less than 2 years. PMID:2957675

    Hundred patients with far-advanced cancer and pain were interviewed within a few days of admission to a special care unit. Eighty had more than one pain; 34 had four or more. A total of 303 anatomically distinct pains were recorded. Ninety-one patients had pain caused by the cancer itself. Twelve had treatment-related pain; and 19 had pain related to chronic disease or debility ('associated pain'). Thirty-nine patients had one or more pains unrelated to cancer or treatment; the most common of these was myofascial pain. In 41 patients only was all the pain caused directly by the cancer. Bone involvement and nerve compression were the most common forms of cancer-related pain; soft tissue and visceral pains also occurred frequently. Fifty-seven patients had pain for more than 4 months. PMID:6218464

    Chronic pain is usually underestimated in children, due to lack of knowledge and its specific signs. In addition to suffering, chronic pain causes a physical, psychological, emotional, social, and financial burden for the child and his family. Practitioners may find themselves in a situation of failure with depletion of medical resources. Some types of chronic pain are refractory to conventional systemic treatment and may require the use of regional anesthesia. Cancer pain is common in children and its medical management is sometimes insufficient. It is accessible to neuroaxial or peripheral techniques of regional anesthesia if it is limited to an area accessible to one of these techniques and no contraindications (e.g., thrombopenia) are present. Complex regional pain syndrome 1 is not rare in children and adolescents, but it often goes undiagnosed. Regional anesthesia may contribute to the treatment of complex regional pain syndrome 1, mainly in case of recurrence, because it provides rapid effective analgesia and allows rapid implementation of intensive physiotherapy. These techniques have also shown interest in phantom limb pain after limb amputation, but they remain controversial for erythromelalgia pain or chronic abdominopelvic pain. Finally, the treatment of postdural puncture headache due to cerebrospinal fluid leak can be treated by performing an epidural injection of the patient's blood, called a blood-patch. Finally, the management of children with chronic pain should be multidisciplinary (pediatrician, physiotherapist, psychologist, surgeon, anesthesiologist) to support the child and her problem in its entirety.

    Purpose of review Most individuals who develop pain following an inciting event will return to a healthy state as the injury heals. However, a small percentage continue to suffer, that is, transition to chronic pain. Chronic pain may persist for years and is accompanied by cognitive abnormalities, as well as diminished quality of life. In animals, persistent pain is characterized by peripheral and spinal cord reorganization, and recent evidence in humans also indicates cortical reorganization. Yet, despite more than 30 years of research, there is little agreement on the neural mechanisms that mediate the transition from acute to chronic pain. Recent findings In a longitudinal brain-imaging study, individuals who developed an intense back pain episode were followed over a 1-year period, during which pain and brain parameters were collected repeatedly. A smaller number of healthy individuals and chronic back pain patients were also studied concomitantly, as positive and negative controls. At the time of entry into the study, strength of synchrony between the medial prefrontal cortex and nucleus accumbens (i.e. functional connectivity) was predictive (>80% accuracy) of individuals who subsequently transition to chronicity 1 year later. Summary Properties of the brain’s emotional learning circuitry predict the transition to chronic pain. The involvement of this circuitry in pain remains mostly unexplored. Future human and animal model studies are necessary to unravel underlying mechanisms driving pain chronicity, with the potential of advancing novel therapeutics for preventing pain chronification.

    In the past decade, the literature on chronic pain shows an increasing interest in the relationship between patients' locus of control (LOC) beliefs and their responses to the chronic pain experience [1-5]. However, few of these studies assess the relationships between ethnic or cultural background and LOC style in the chronic pain experience--despite research suggesting that culture affects chronic pain responses [6-8]. This report of two quantitative and qualitative research projects among chronic pain sufferers in New England and in Puerto Rico, shows significant relationships between patients' LOC style and variations in reported chronic pain intensity and responses. Our studies also demonstrate a relationship between LOC style and ethnic or cultural background and an interaction between LOC style and cultural identity in variations in reported pain intensity. In addition, we found intra-ethnic/cultural-group variations in the pain experience related to LOC style. In these chronic pain populations, the qualitative data further suggests that LOC style may not be a permanent, unchanging characteristic or cognitive interpretation. Instead, an individual's LOC style may be altered by the chronic pain experience and such a style may change at various stages in the chronic pain 'career'. These studies also show that in many ethnic/cultural groups, an increased sense of control may contribute to an increased ability to cope successfully with the chronic pain experience. In light of these findings, we suggest that it may be possible to alter a patient's sense of control through the development of deliberate culturally appropriate and personally relevant programs designed to help the patients establish a sense of control over their lives and their pain.

    The benefit of exercise for pain control likely comes from the impact of exercise on the endogenous opioid system and on central pain modulatory systems. Patients with some chronic pain conditions seem to have a dysfunctional endogenous pain modulatory system, which should be considered when prescribing exercise. The prescription of exercise for chronic pain must address the biomechanical issues and the psychosocial factors that contribute to the patient's pain and disability. Patient education, coordination of care within the health care team, and selecting an exercise regimen that is meaningful to and achievable by the patient are all important components to promote a successful rehabilitation program.

    Chronic musculoskeletal pain results from a complex interplay of mechanical, biochemical, psychological, and social factors. Effective management is markedly different from that of acute musculoskeletal pain. Understanding the physiology of pain transmission, modulation, and perception is crucial for effective management. Pharmacologic and nonpharmacologic therapies such as psychotherapy and biofeedback exercises can be used to manage chronic pain. Evidence-based treatment recommendations have been made for chronic pain conditions frequently encountered by orthopaedic surgeons, including low back, osteoarthritic, posttraumatic, and neuropathic pain. Extended-release tramadol; select tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants; and topical medications such as lidocaine, diclofenac, and capsaicin are among the most effective treatments. However, drug efficacy varies significantly by indication. Orthopaedic surgeons should be familiar with the widely available safe and effective nonnarcotic options for chronic musculoskeletal pain.

The Centers for Disease Control and Prevention (CDC) developed and published the Guideline for Prescribing Opioids for Chronic Pain to provide recommendations for the prescribing of opioid pain medication for patients 18 and older in primary care settings. Recommendations focus on the use of opioids in treating chronic pain (pain lasting longer than 3 months or past the time of normal tissue healing) outside of active cancer treatment, palliative care, and end-of-life care.

    Cancer and its treatment exert a heavy psychological and physical toll. Of the myriad symptoms which result, pain is common, encountered in between 30% and 60% of cancer survivors. Pain in cancer survivors is a major and growing problem, impeding the recovery and rehabilitation of patients who have beaten cancer and negatively impacting on cancer patients’ quality of life, work prospects and mental health. Persistent pain in cancer survivors remains challenging to treat successfully. Pain can arise both due to the underlying disease and the various treatments the patient has been subjected to. Chemotherapy causes painful chemotherapy-induced peripheral neuropathy (CIPN), radiotherapy can produce late effect radiation toxicity and surgery may lead to the development of persistent post-surgical pain syndromes. This review explores a selection of the common causes of persistent pain in cancer survivors, detailing our current understanding of the pathophysiology and outlining both the clinical manifestations of individual pain states and the treatment options available.

    We present the case of a 56-year-old man who developed chronic pain following the excision of a facial cancer that was poorly controlled despite multiple analgesic medications. Following the starting of nabilone (a synthetic cannabinoid) his pain control was greatly improved and this had a huge impact on his quality of life. We also managed to significantly reduce his doses of opioid analgesia and ketamine. We review the current literature regarding the medicinal use of cannabinoids, with an emphasis on chronic pain, in an attempt to clarify their role and how to select patients who may benefit from this treatment.

    Background This is an update of the original Cochrane review published in Issue 2, 2007. Some antiepileptic medicines have a place in the treatment of neuropathic pain (pain due to nerve damage). This updated review adds five new additional studies looking at evidence for Lamotrigine as an effective treatment for acute and chronic pain. Objectives To assess analgesic efficacy and adverse effects of the antiepileptic drug lamotrigine in acute and chronic pain. Search methods Randomised controlled trials (RCTs) of lamotrigine in acute, and chronic pain (including cancer pain) were identified from MEDLINE, EMBASE and CENTRAL up to January 2011. Additional studies were sought from the reference list of the retrieved papers. Selection criteria RCTs investigating the use of lamotrigine (any dose, by any route, and for any study duration) for the treatment of acute or chronic pain. Assessment of pain intensity or pain relief, or both, using validated scales. Participants were adults aged 18 and over. Only full journal publication articles were included. Data collection and analysis Dichotomous data (ideally for the outcome of at least 50% pain relief) were used to calculate relative risk with 95% confidence intervals. Meta-analysis was undertaken using a fixed-effect model. Numbers needed to treat to benefit (NNTs) were calculated as the reciprocal of the absolute risk reduction. For unwanted effects, the NNT becomes the number needed to harm (NNH) and was calculated. Main results Twelve included studies in 11 publications (1511 participants), all with chronic neuropathic pain: central post stroke pain (1), chemotherapy induced neuropathic pain (1), diabetic neuropathy (4), HIV related neuropathy (2), mixed neuropathic pain (2), spinal cord injury related pain (1), and trigeminal neuralgia (1); none investigated lamotrigine in acute pain. The update had five additional studies (1111 additional participants). Participants were aged between 26 and 77 years. Study duration

    In the last 2 decades, a growing body of research aimed at investigating the health benefits of Tai Chi in various chronic health conditions has been recognized in the literature. This article reviewed the history, the philosophy, and the evidence for the role of Tai Chi in a few selected chronic pain conditions. The ancient health art of Tai Chi contributes to chronic pain management in 3 major areas: adaptive exercise, mind-body interaction, and meditation. Trials examining the health benefit of Tai Chi in chronic pain conditions are mostly low quality. Only 5 pain conditions were reviewed: osteoarthritis, fibromyalgia, rheumatoid arthritis, low back pain, and headache. Of these, Tai Chi seems to be an effective intervention in osteoarthritis, low back pain, and fibromyalgia. The limitations of the Tai Chi study design and suggestions for the direction of future research are also discussed. PMID:22609642

    We studied the associations of widespread pain with other pain and functional measures among patients with chronic epicondylitis. A total of 190 patients (66% females) participated in the study; with a mean age 43.7, mean duration of symptoms 48weeks, chronic lateral (n=160) and medial (n=30) epicondylitis. We analysed clinical status, grip strength and cubital pain thresholds and interviewed pain and disability, leisure time physical activity, strenuous hobby activities for arms, duration of symptoms, other systemic and upper extremity disorders, arm operations, and work ability. The location of pain was analysed using a whole-body pain drawing, categorized into three groups; the highest of which was classified as widespread pain. A total of 85 patients (45%) reported widespread pain. It was highly associated with female gender, high pain scores, decreased grip strength and pain thresholds (p<0.001 for all), with increased number of positive manual tests, low level of hobby strain for arms and physical activity, long duration of symptoms, and sick leave (p for all <0.05). It was also related to upper extremity disorders and arm surgery, but not with operated epicondylitis, other systemic diseases, workload or work ability. In addition, 39% of patients without other disease reported widespread pain. Widespread pain is common in chronic epicondylitis with and without other diseases, and is related to high pain scores, decreased function of the arm, long duration of symptoms, sick leave, and with a low level of physical activity.

    Neuropathic pain in cancer arises following injury to peripheral or central neurons, in a similar manner to such pain arising from a non-cancer injury. Much of our knowledge of neuropathic pain is based on peripheral originating events with little known about central neuropathic pain. This article explores some of the similarities and differences between cancer and non-cancer-related neuropathic pain. The neural pathways, ion channels, receptors and neurotransmitters that potentially can be altered in both neuropathies are the same; however the nature of the injury, the timing, repeated injuries and the co-existence of simultaneous non-neuropathic pain states lead to potential unique constellations of neuroreceptor and neurotransmitter expression in the context of cancer pain. This in turn may lead to different clinical presentation of pain sensations and potentially lead to specific treatment options. PMID:18492553

    Pain persisting for at least 6 months is defined as chronic. Chronic facial pain conditions often take on lives of their own deleteriously changing the lives of the sufferer. Although much is known about facial pain, it is clear that those physicians who treat these conditions should continue elucidating the mechanisms and defining successful treatment strategies for these life-changing conditions. This article will review many of the classic causes of chronic facial pain due to the trigeminal nerve and its branches that are amenable to surgical therapies. Testing of facial sensibility is described and its utility introduced. We will also introduce some of the current hypotheses of atypical facial pain and headaches secondary to chronic nerve compressions and will suggest possible treatment strategies. PMID:22110799

    2014-12-01

    Chronic pain is defined as an unpleasant sensory and emotional experience persisting longer than the normal process of healing, usually longer than 3 months. About a fifth of the world's population is believed to suffer from chronic pain. In Europe, chronic pain accounts for nearly 500 m lost working days, and it costs the European economy >€34 billion (£28 billion) every year. Establishing a reliable diagnosis is the primary challenge in evaluating a patient with chronic pain. Common diagnoses not to miss include seronegative spondyloarthritides, endocrine abnormalities including severe vitamin D deficiency and polymyalgia rheumatica. Once important or treatable diagnoses have been ruled out, the history can be used as a tool to establish a therapeutic plan for shared decision-making using the biopsychosocial model. Onward referral to pain clinics can be helpful for more involved patient management, but often good outcomes are achieved with the support of primary care. PMID:26096090

    Objective This study aimed to investigate the efficacy of intrathecal morphine in the long term by hypothesising that a reduction of the intrathecal opioid dose following long-term administration would increase the level of pain intensity. Design Randomised, double-blind, controlled, parallel group trial. Setting Department of Pain Management, Russells Hall Hospital, Dudley, UK. Participants 24 patients with non-cancer pain implanted with morphine reservoirs were assessed for eligibility. Interventions Participants were randomly allocated to one of two parallel groups in which one of the groups had no change in morphine dose and the other group had a small reduction (20%) in dosage every week during a 10-week follow-up. Outcome Primary outcomes were visual analogue scale (VAS) pain score change and withdrawal from the study due to lack of efficacy. Results 9 of the patients assessed for eligibility declined to participate in the study. 15 patients were randomised to control (n=5) or intervention (n=10) and included in an intention-to-treat analysis. Owing to worsening of pain, seven patients withdrew from the study prematurely. None knew prior to withdrawal which arm of the study they were in, but all turned out to be in the dose-reduction arm. The calculation of dropout rates between groups indicated a significant statistical difference (p=0.026) and recruitment was ceased. The VAS change between baseline and the last observation was smaller in the control group (median, Mdn=11) than in the intervention group (Mdn=30.5), although not statistically significant, Z=−1.839, p=0.070; r=−0.47. Within groups, VAS was significantly lower at baseline (Mdn=49.5) than at the last observation (Mdn=77.5) for the reduction group, Z=−2.805, p=0.002; r=−0.627 but not for the control group (p=0.188). Conclusions This double-blind randomised controlled trial of chronic intrathecal morphine administration suggests the effectiveness of this therapy for the management of

    All chronic pain begins at some discrete point in time. Significant strides in the understanding of mechanisms and risk factors associated with the transition from a new, or acute, pain experience to a chronic pain condition have been made over the past 20 years. These insights provide the hope of one day being able to modify or even halt this pathophysiologic progression. This article reviews some of the current knowledge of this transition as well as the evidence currently available to best prevent and treat it using persistent surgical pain as a model.

    Chronic pain is a debilitating condition with major socioeconomic impact, whose neurobiological basis is still not clear. An involvement of the neurovascular unit (NVU) has been recently proposed. In particular, the blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB), two NVU key players, may be affected during the development of chronic pain; in particular, transient permeabilization of the barrier is suggested by several inflammatory- and nerve-injury-based pain models, and we argue that the clarification of molecular BBB/BSCB permeabilization events will shed new light in understanding chronic pain mechanisms. Possible biases in experiments supporting this theory and its translational potentials are discussed. Moving beyond an exclusive focus on the role of the endothelium, we propose that our understanding of the mechanisms subserving chronic pain will benefit from the extension of research efforts to the NVU as a whole. In this view, the available evidence on the interaction between analgesic drugs and the NVU is here reviewed. Chronic pain comorbidities, such as neuroinflammatory and neurodegenerative diseases, are also discussed in view of NVU changes, together with innovative pharmacological solutions targeting NVU components in chronic pain treatment.

    Chronic pain is common. Many patients with cancer and other life-limiting illnesses have chronic pain that is related to their disease, and some have comorbid chronic nonmalignant chronic pain. As palliative care continues to move upstream and outpatient palliative care programs develop, palliative care clinicians will be called upon to treat chronic pain. Chronic pain differs from acute pain in the setting of advanced disease and a short prognosis in terms of its etiology, comorbidities-especially psychiatric illness and substance abuse-and management. To successfully care for these patients, palliative care providers will need to learn new clinical competencies. This article will review chronic pain management core competencies for palliative care providers. PMID:22556285

    Chronic pain arising from peripheral inflammation and tissue or nerve injury is a common clinical symptom. Although intensive research on the neurobiological mechanisms of chronic pain has been carried out during previous decades, this disorder is still poorly managed by current drugs such as opioids and nonsteroidal anti-inflammatory drugs. Inflammation, tissue injury and/or nerve injury-induced changes in gene expression in sensory neurons of the dorsal root ganglion, spinal cord dorsal horn and pain-associated brain regions are thought to participate in chronic pain genesis; however, how these changes occur is still elusive. Epigenetic modifications including DNA methylation and covalent histone modifications control gene expression. Recent studies have shown that peripheral noxious stimulation changes DNA methylation and histone modifications and that these changes may be related to the induction of pain hypersensitivity under chronic pain conditions. This review summarizes the current knowledge and progress in epigenetic research in chronic pain and discusses the potential role of epigenetic modifications as therapeutic antinociceptive targets in this disorder.

    Chronic pelvic pain in women is defined as persistent, noncyclic pain perceived to be in structures related to the pelvis and lasting more than six months. Often no specific etiology can be identified, and it can be conceptualized as a chronic regional pain syndrome or functional somatic pain syndrome. It is typically associated with other functional somatic pain syndromes (e.g., irritable bowel syndrome, nonspecific chronic fatigue syndrome) and mental health disorders (e.g., posttraumatic stress disorder, depression). Diagnosis is based on findings from the history and physical examination. Pelvic ultrasonography is indicated to rule out anatomic abnormalities. Referral for diagnostic evaluation of endometriosis by laparoscopy is usually indicated in severe cases. Curative treatment is elusive, and evidence-based therapies are limited. Patient engagement in a biopsychosocial approach is recommended, with treatment of any identifiable disease process such as endometriosis, interstitial cystitis/painful bladder syndrome, and comorbid depression. Potentially beneficial medications include depot medroxyprogesterone, gabapentin, nonsteroidal anti-inflammatory drugs, and gonadotropin-releasing hormone agonists with add-back hormone therapy. Pelvic floor physical therapy may be helpful. Behavioral therapy is an integral part of treatment. In select cases, neuromodulation of sacral nerves may be appropriate. Hysterectomy may be considered as a last resort if pain seems to be of uterine origin, although significant improvement occurs in only about one-half of cases. Chronic pelvic pain should be managed with a collaborative, patient-centered approach. PMID:26926975

When considering nerve blocks for chronic pain, clinicians must always consider the indications, risks, benefits, and proper technique. Nerve blocks encompass a wide variety of interventional procedures. The most common nerve blocks for chronic pain and that may be applicable to the neurosurgical patient population are reviewed in this article.

    PubMed Central

    Ji, Ru-Rong; Berta, Temugin; Nedergaard, Maiken

    2013-01-01

    Activation of glial cells and neuro-glial interactions are emerging as key mechanisms underlying chronic pain. Accumulating evidence has implicated 3 types of glial cells in the development and maintenance of chronic pain: microglia and astrocytes of the central nervous system (CNS), and satellite glial cells of the dorsal root and trigeminal ganglia. Painful syndromes are associated with different glial activation states: (1) glial reaction (ie, upregulation of glial markers such as IBA1 and glial fibrillary acidic protein (GFAP) and/or morphological changes, including hypertrophy, proliferation, and modifications of glial networks); (2) phosphorylation of mitogen-activated protein kinase signaling pathways; (3) upregulation of adenosine triphosphate and chemokine receptors and hemichannels and downregulation of glutamate transporters; and (4) synthesis and release of glial mediators (eg, cytokines, chemokines, growth factors, and proteases) to the extracellular space. Although widely detected in chronic pain resulting from nerve trauma, inflammation, cancer, and chemotherapy in rodents, and more recently, human immunodeficiency virus-associated neuropathy in human beings, glial reaction (activation state 1) is not thought to mediate pain sensitivity directly. Instead, activation states 2 to 4 have been demonstrated to enhance pain sensitivity via a number of synergistic neuro-glial interactions. Glial mediators have been shown to powerfully modulate excitatory and inhibitory synaptic transmission at presynaptic, postsynaptic, and extrasynaptic sites. Glial activation also occurs in acute pain conditions, and acute opioid treatment activates peripheral glia to mask opioid analgesia. Thus, chronic pain could be a result of “gliopathy,” that is, dysregulation of glial functions in the central and peripheral nervous system. In this review, we provide an update on recent advances and discuss remaining questions. PMID:23792284

    Chronic leg pain is commonly treated by orthopaedic surgeons who take care of athletes. The sources are varied and include the more commonly encountered medial tibial stress syndrome, chronic exertional compartment syndrome, stress fracture, popliteal artery entrapment syndrome, nerve entrapment, Achilles tightness, deep vein thrombosis, and complex regional pain syndrome. Owing to overlapping physical examination findings, an assortment of imaging and other diagnostic modalities are employed to distinguish among the diagnoses to guide the appropriate management. Although most of these chronic problems are treated nonsurgically, some patients require operative intervention. For each condition listed above, the pathophysiology, diagnosis, management option, and outcomes are discussed in turn. PMID:25157051

    Objectives Little is known about the treatment Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans receive for chronic non-cancer pain (CNCP). We sought to describe the prevalence of prescription opioid use, types and doses of opioids received, and identify correlates of receiving prescription opioids for CNCP among OEF/OIF veterans. Design Retrospective review of VA administrative data. Setting Ambulatory clinics within a VA regional healthcare network. Patients OEF/OIF veterans who had at least 3 elevated pain screening scores within a 12-month period in 2008. Within this group, those prescribed opioids (n=485) over the next 12 months were compared to those not prescribed opioids (n=277). In addition, patients receiving opioids short term (<90 days, n=284) were compared to patients receiving them long-term (≥90 consecutive days, n=201). Results Of 762 OEF/OIF veterans with CNCP, 64% were prescribed at least one opioid medication over the 12 months following their index dates. Of those prescribed an opioid, 59% were prescribed opioids short-term and 41% were prescribed opioids long-term. The average morphine-equivalent opioid dose for short-term users was 23.7 mg (SD=20.5) compared with 40.8 mg (SD=36.1) for long-term users (p<0.001). Fifty-one percent of long-term opioid users were prescribed short-acting opioids only and one-third were also prescribed sedative-hypnotics. In adjusted analyses, diagnoses of low back pain, migraine headache, post-traumatic stress disorder, and nicotine use disorder were associated with an increased likelihood of receiving an opioid prescription. Conclusion Prescription opioid use is common among OEF/OIF veterans with CNCP and is associated with several pain diagnoses and medical conditions. PMID:21899715

    This manuscript, developed by a group of chronic pain researchers and clinicians from around the world, aims to address the state of knowledge about fibromyalgia (FM) and identify ongoing challenges in the field of FM and other chronic pain syndromes that may be characterized by pain centralization/amplification/hypersensitivity. There have been many exciting developments in research studies of the pathophysiology and treatment of FM and related syndromes that have the potential to improve the recognition and management of patients with FM and other conditions with FM-like pain. However, much of the new information has not reached all clinicians, especially primary care clinicians, who have the greatest potential to use this new knowledge to positively impact their patients’ lives. Furthermore, there are persistent misconceptions about FM and a lack of consensus regarding the diagnosis and treatment of FM. This paper presents a framework for future global efforts to improve the understanding and treatment of FM and other associated chronic pain syndromes, disseminate research findings, identify ways to enhance advocacy for these patients, and improve global efforts to collaborate and reach consensus about key issues related to FM and chronic pain in general.

    Introduction Intrathecal drug delivery (ITDD) systems are an option for the management of patients with chronic non-cancer pain, cancer pain and spasticity. Concerns over their invasiveness and high initial costs have led National Health Service (NHS) England to decommission ITDD for patients with chronic non-cancer pain. However, the extent to which this decision is in line with existing economic evidence is unclear. To address this question, we will carry out a systematic review to identify and evaluate the existing evidence on the cost-effectiveness of ITDD for chronic non-cancer pain. Methods and analysis A high-sensitivity search strategy will be employed in Cochrane Library, MEDLINE, EMBASE, Web of Science, NHS EED, DARE and HTA. Database searches will be complemented by additional searching techniques. Screening of the results will be performed by 2 reviewers independently using predetermined inclusion and exclusion criteria. Full and partial economic evaluations will be included. Data extraction will be carried out using a form created for the purposes of this review. Quality assessment of all included studies will be performed using recommended checklists. Ethics and dissemination Ethical approval is not required as primary data will not be collected. Findings will be disseminated through peer-reviewed publications and conference presentations.

    Pain is a real issue of public health, quality and evolution of a system of health test: this is a major social problem. Pain management meets a humanistic, ethical purpose and dignity of man because of the physical and psychological implications. It induces a disability which excludes the patient of society gradually or suddenly. The physical pain and mental suffering to all ages of life make more vulnerable people weakened by disease. Rebel chronic pain are sources of disability, disabilities, disability and major alterations in the quality of life. All of these data shows the impact of pain and its intensity on the professional conditions, on professional activity and productivity, on the use of care systems (very significant increase in medical consultations, hospitalizations), as well as on the mental and physical health. These results confirmed analyses which consider that the unrelieved pain has a major economic impact on care systems and constitutes a public health problem with around two thirds of persons professionally impacted by pain. The progress of medicine has helped the healing of certain serious diseases, but also favoured acute diseases to turn to chronic diseases. The result is an increase in of lifetime sometimes without disease, but this survival may be also accompanied by disease or disability. Progress, pain and suffering, the end of life, ethics will be the core of the basic thoughts of tomorrow. PMID:27509674

    Objective Chronic pain affects both psychological and physical functioning, and is responsible for more than $60 billion in lost productivity annually in the United States. Although previous studies have demonstrated racial disparities in opioid treatment, there is little evidence regarding disparities in treatment of chronic non-cancer pain (CNCP) and the role of physician specialty. Design A retrospective cohort study. Setting We analyzed North Carolina Medicaid claims data, from July 1, 2009 to May 31, 2010, to examine disparities by different provider specialties in beneficiaries dispensed prescriptions for opioids. Subjects The population included White and Black North Carolina Medicaid beneficiaries with CNCP (n=75,458). Methods We used bivariate statistics and logistic regression analysis to examine race-based discrepancies in opioid prescribing by physician specialty. Results Compared to White beneficiaries with CNCP (n=49,197), Black beneficiaries (n=26,261) were less likely [OR 0.91 (CI: 0.88–0.94)] to fill an opioid prescription. Our hypothesis was partially supported: we found that race-based differences in beneficiaries dispensed opioid prescriptions were more prominent in certain specialties. In particular, these differences were most salient among patients of specialists in obstetrics and gynecology [OR 0.78 (CI: 0.67–0.89)] and internal medicine [OR 0.86 (CI: 0.79–0.92)], as well as general practitioners/family medicine physicians [OR 0.91 (CI: 0.85–0.97)]. Conclusions Our findings suggest that, in our study population, Black beneficiaries with CNCP are less likely than Whites to fill prescriptions for opioid analgesics as a function of their provider’s specialty.

    2012-01-01

    The patients with chronic pain are increasingly reporting to the physicians for its management. Chronic pain are associated with head, neck and shoulder pain, spinal pain, pain in the joints and extremities, complex regional pain syndrome and phantom pain. The chronic pain is being managed worldwide. The different specialty of medicine is producing a lot of evidence through the published literature but the same is not being published in the field of chronic pain management. Though some evidence is being reported as to different aspects of pain management from different parts of the world but same is lacking from Indian subcontinent. This is in contrast to much done clinical work in this field as well. We present here the available evidence in relation to chronic pain management. PMID:23439674

  8. Melatonin in Chronic Pain Syndromes.

    PubMed

    Danilov, Andrei; Kurganova, Julia

    2016-06-01

    Melatonin is a neurohormone secreted by epiphysis and extrapineal structures. It performs several functions including chronobiotic, antioxidant, oncostatic, immune modulating, normothermal, and anxiolytic functions. Melatonin affects the cardiovascular system and gastrointestinal tract, participates in reproduction and metabolism, and body mass regulation. Moreover, recent studies have demonstrated melatonin efficacy in relation to pain syndromes. The present paper reviews the studies on melatonin use in fibromyalgia, headaches, irritable bowel syndrome, chronic back pain, and rheumatoid arthritis. The paper discusses the possible mechanisms of melatonin analgesic properties. On one hand, circadian rhythms normalization results in sleep improvement, which is inevitably disordered in chronic pain syndromes, and activation of melatonin adaptive capabilities. On the other hand, there is evidence of melatonin-independent analgesic effect involving melatonin receptors and several neurotransmitter systems. PMID:26984272

    2016-06-01

    Opioids prescribed for chronic cancer and noncancer pain have been embroiled in public policy debates as to effectiveness and potential for contributing to society's problem with misuse, addiction, and overdose mortality. The conundrum of opioid prescribing is to determine who will most likely benefit from opioids and how medical practitioners may safely provide chronic opioid therapy, while also identifying patients who are unlikely to benefit or could divert illicit pharmaceuticals into society. Risk assessment and monitoring are essential to meet the standard of care, as is compliance with federal controlled substances law as well as state regulations. PMID:27208714

  10. Opioids for chronic non-cancer pain: a protocol for a systematic review of randomized controlled trials

    PubMed Central

    2013-01-01

    Background Opioids are prescribed frequently and increasingly for the management of chronic non-cancer pain (CNCP). Current systematic reviews have a number of limitations, leaving uncertainty with regard to the benefits and harms associated with opioid therapy for CNCP. We propose to conduct a systematic review and meta-analysis to summarize the evidence for using opioids in the treatment of CNCP and the risk of associated adverse events. Methods and design Eligible trials will include those that randomly allocate patients with CNCP to treatment with any opioid or any non-opioid control group. We will use the guidelines published by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) to inform the outcomes that we collect and present. We will use the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system to evaluate confidence in the evidence on an outcome-by-outcome basis. Teams of reviewers will independently and in duplicate assess trial eligibility, abstract data, and assess risk of bias among eligible trials. To ensure interpretability of our results, we will present risk differences and measures of relative effect for all outcomes reported and these will be based on anchor-based minimally important clinical differences, when available. We will conduct a priori defined subgroup analyses consistent with current best practices. Discussion Our review will evaluate both the effectiveness and the adverse events associated with opioid use for CNCP, evaluate confidence in the evidence using the GRADE approach, and prioritize patient-important outcomes with a focus on functional gains guided by IMMPACT recommendations. Our results will facilitate evidence-based management of patients with CNCP and identify key areas for future research. Trial registration Our protocol is registered on PROSPERO (CRD42012003023), http://www.crd.york.ac.uk/PROSPERO. PMID:23965223

    2014-01-01

    Modern methods of brain imaging have enabled objective measurements of functional and structural brain changes associated with chronic pain conditions. According to recent investigations, chronic pain is not only associated with abnormally strong or prolonged activity of regions processing acute pain, but also with activation of brain networks that are characteristic for each pain state, changes in cortical remodeling, as well as local reduction of grey matter in several regions of the brain. Brain changes associated with chronic pain facilitate the understanding of mechanisms of various chronic pain conditions. PMID:25211820

    Cognitive behavioral therapy (CBT) is often used to treat chronic pain; however, more information is needed about what are the most efficacious dose and delivery methods. The aims of this review were to determine (a) which CBT doses, delivery methods, strategies, and follow-up periods have been explored in recent intervention studies of individuals with chronic pain and (b) whether the outcomes described in the selected studies were consistent with recommendations by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials. The CINAHL, EMBASE, PubMed, PsycInfo, and SCOPUS databases were searched for randomized controlled trials published from 2009 to 2015 testing CBT for adults with chronic pain. Thirty-five studies were included in this review. Results revealed that CBT reduced pain intensity in 43% of trials, the efficacy of online and in-person formats were comparable, and military veterans and individuals with cancer-related chronic pain were understudied.

    2015-05-01

    Legal and licensure issues are an inevitable aspect of treating patients with chronic pain. Clinicians need to ensure compliance with state medical board and federal guidelines. Prescription drug abuse continues to be a significant problem. Despite the legalization of medical marijuana in some states, there is currently no medical indication for prescribing marijuana; the exceptions are dronabinol and nabilone. These are approved by the Food and Drug Administration for chemotherapy-induced nausea and vomiting, and dronabinol also is approved for anorexia in patients with AIDS or cancer. Other legal issues concern establishment of chronic pain as a basis for disability status. Clinicians often are asked to provide a letter or assessment, such as a functional capacity evaluation, for documenting disability. Referral to a physical medicine and rehabilitation subspecialist or physical therapist for this evaluation should be considered. Balancing legal and licensure issues with the best interests of the patient can be challenging for clinicians. PMID:25970871

    PubMed Central

    Tuttle, C B

    1985-01-01

    Chronic severe cancer pain is often not well controlled because both patient and physician have a poor understanding of the nature of the pain and of the actions of various potent analgesics. Physicians often fail to tailor analgesic dosages to the needs of the individual and unnecessarily limit the dosage because they have an ill founded fear that the patient will become addicted. The basis of rational management of cancer pain with drugs is an appropriate analgesic given regularly in doses adequate to suppress pain continuously. This review compares the potent analgesics and identifies and discusses those that have a role in treating chronic cancer pain. It emphasizes the value of morphine sulfate and gives information on starting and individualizing dosages and managing side effects. PMID:2856896

  15. Endometriosis and Chronic Pelvic Pain

    PubMed Central

    Bloski, Terri; Pierson, Roger

    2010-01-01

    Nurses often encounter patients with chronic pelvic pain associated with endometriosis, which is a puzzling and problematic gynecologic condition that has continued to plague women and baffle doctors and researchers worldwide since it was first identified by Dr. J. Sampson in the 1920s (Sampson, 1940). Endometriosis is defined as the growth, adhesion and progression of endometrial glands and stroma outside of the uterine cavity, with cellular activity evident in lesions, nodules, cysts or endometriomas (Audebert et al., 1992). Although it typically appears benign on histopathology, endometriosis has been likened to a malignant tumor since the lesions grow, infiltrate and adhere to adjacent tissues and interfere with physiologic processes (Kitawaki et al., 2002; Noble, Simpson, Johns, & Bulun, 1996). Ectopic endometriotic growths respond to cyclic changes of estrogen and proliferate and shed in a manner similar to eutopic endometrium. This cyclic ectopic activity results in internal bleeding, formation of scar tissue, inflammation and sometimes debilitating chronic pain (Kitawaki et al.). PMID:18837717

  16. Alexithymia in Chronic Pain Disorders.

    PubMed

    Di Tella, Marialaura; Castelli, Lorys

    2016-07-01

    This review proposes a critical discussion of the recent studies investigating the presence of alexithymia in patients suffering from different chronic pain (CP) conditions. The term CP refers to pain that persists or progresses over time, while alexithymia is an affective dysregulation, largely observed in psychosomatic diseases. Overall, the examined studies showed a high prevalence of alexithymia, especially difficulties in identifying feelings, in all the different CP conditions considered. However, the association between alexithymia and pain intensity was not always clear and in some studies this relationship appeared to be mediated by negative effect, especially depression. The role of alexithymia in CP should be clarified by future studies, paying particular attention to two aspects: the use of additional measures, in addition to the Toronto Alexithymia Scale, to assess alexithymia, and the analysis of the potential differences in the evolution of different CP conditions with reference to the presence or absence of alexithymia.

    Children with chronic pain often undergo surgery and effective perioperative management of their pain can be challenging. Identification of the pediatric chronic pain patient preoperatively and development of a perioperative pain plan may help ensure a safer and more comfortable perioperative course. Successful management usually requires multiple different classes of analgesics, regional anesthesia, and adjunctive nonpharmacological therapies. Neuropathic and oncological pain can be especially difficult to treat and usually requires an individualized approach. PMID:27370517

    2013-01-01

    Cancerous cells can originate in a number of different tissues such as prostate, breast and lung, yet often go undetected and are non-painful. Many types of cancers will metastasize toward the bone microenvironment first. Tumor burden within the bone causes excruciating breakthrough pain with properties of continual pain inadequately managed with current analgesics. Part of this failure is due to the poor understanding of the etiology of cancer pain. Animal models of cancer-induced bone pain (CIBP) have revealed that the neurochemistry of cancer has features distinctive from other chronic pain states. For example, preclinical models of metastatic cancer often result in the upregulation of neurotrophins, such as NGF and BDNF that can lead to nociceptive sensitization. Preclinical cancer models demonstrate nociceptive neuronal expression of acid sensing receptors, such as ASIC1 and TRPV1 that respond to a significant increase in an acidic cancer-induced environment within the bone. CIBP is correlated with a significant increase in pro-inflammatory mediators acting peripherally and centrally, contributing to neuronal hypersensitive states. And finally, cancer cells generate high levels of oxidative molecules that are thought to significantly increase extracellular glutamate, thus activating primary afferent neurons. Knowledge of the unique neuro-molecular profile of cancer pain will ultimately lead to the development of novel and superior therapeutics for CIBP. PMID:24076008

    Breast cancer surgery is known to cause severe acute postoperative pain, which can persist for a long time. We administered nefopam preventively to patients undergoing lumpectomy with axillary lymph node dissection or sentinel lymph node biopsy, and evaluated its efficacy on acute and chronic postoperative pain.Enrolled patients were assigned to the nefopam (n = 41) or the control (n = 42) group. Before initiating the operation, 20 mg of nefopam was given to the patients of the nefopam group, and normal saline was used in the control group. Ketorolac was given at the end of surgery, and meloxicam was prescribed in the postoperative period to all patients in both groups. Pain was assessed using a numerical rating scale (NRS), and the rescue analgesic drug was given when the NRS was >5. Implementation of postoperative chemotherapy, radiotherapy (RT), or hormone therapy was evaluated.The NRS of postoperative pain was significantly lower in the nefopam than in the control group in the postanesthetic care unit (4.5 ± 2.2 vs 5.7 ± 1.5, respectively; P = 0.01), at postoperative 6 h (3.0 ± 1.6 vs 4.5 ± 1.3, respectively; P < 0.001), and at postoperative 24 h (3.1 ± 1.1 vs 3.8 ± 1.5, respectively; P = 0.01) with reduced use of rescue analgesic drugs. Significantly fewer patients suffered from chronic postoperative pain in the nefopam than in the control group at postoperative 3 months (36.6% vs 59.5%, P = 0.04). Considering only the cohort without postoperative adjuvant RT, the difference in the proportion of patients reporting chronic pain increased (23.5% in the nefopam group vs 61.5% in the control group, P = 0.04).Preventive nefopam was helpful in reducing the acute postoperative pain, with reduced use of rescue analgesic drugs, and it contributed to reduced occurrence of chronic pain at postoperative 3 months after breast cancer surgery.

    In this review we integrate recent human and animal studies from the viewpoint of chronic pain. First, we briefly review the impact of chronic pain on society and address current pitfalls of its definition and clinical management. Second, we examine pain mechanisms via nociceptive information transmission cephalad and its impact and interaction with the cortex. Third, we present recent discoveries on the active role of the cortex in chronic pain, with findings indicating that the human cortex continuously reorganizes as it lives in chronic pain. We also introduce data emphasizing that distinct chronic pain conditions impact on the cortex in unique patterns. Fourth, animal studies regarding nociceptive transmission, recent evidence for supraspinal reorganization during pain, the necessity of descending modulation for maintenance of neuropathic behavior, and the impact of cortical manipulations on neuropathic pain is also reviewed. We further expound on the notion that chronic pain can be reformulated within the context of learning and memory, and demonstrate the relevance of the idea in the design of novel pharmacotherapies. Lastly, we integrate the human and animal data into a unified working model outlining the mechanism by which acute pain transitions into a chronic state. It incorporates knowledge of underlying brain structures and their reorganization, and also includes specific variations as a function of pain persistence and injury type, thereby providing mechanistic descriptions of several unique chronic pain conditions within a single model.

  2. Chronic Pain after Inguinal Hernia Repair

    PubMed Central

    Background. Chronic postherniorrhaphy groin pain is defined as pain lasting >6 months after surgery, which is one of the most important complications occurring after inguinal hernia repair, which occurs with greater frequency than previously thought. Material and Methods. Patients undergoing elective inguinal hernioplasty in Victoria Hospital from November 2011 to May 2013 were included in the study. A total of 227 patients met the inclusion criteria and were available for followup at end of six months. Detailed preoperative, intraoperative, and postoperative details of cases were recorded according to proforma. The postoperative pain and pain at days two and seven and at end of six months were recorded on a VAS scale. Results. Chronic pain at six-month followup was present in 89 patients constituting 39.4% of all patients undergoing hernia repair. It was seen that 26.9% without preoperative pain developed chronic pain whereas 76.7% of patients with preoperative pain developed chronic pain. Preemptive analgesia failed to show statistical significance in development of chronic pain (P = 0.079). Nerve injury was present in 22 of cases; it was found that nerve injury significantly affected development of chronic pain (P = 0.001). On multivariate analysis, it was found that development of chronic pain following hernia surgery was dependent upon factors like preoperative pain, type of anesthesia, nerve injury, postoperative local infiltration, postoperative complication, and most importantly the early postoperative pain. Conclusions. In the present study, we found that chronic pain following inguinal hernia repair causes significant morbidity to patients and should not be ignored. Preemptive analgesia and operation under local anesthesia significantly affect pain. Intraoperative identification and preservation of all inguinal nerves are very important. Early diagnosis and management of chronic pain can remove suffering of the patient.

    The global burden of cancer pain is enormous and opioids, despite their side effects, remain the primary therapeutic approach. The cause of cancer pain is unknown. Mechanisms driving cancer pain differ from those mechanisms responsible for inflammatory and neuropathic pain. The prevailing hypothesis put forward to explain cancer pain posits that cancers generate and secrete mediators which sensitize and activate primary afferent nociceptors in the cancer microenvironment. Moreover, cancers induce neurochemical reorganization of the spinal cord, which contributes to spontaneous activity and enhanced responsiveness. The purpose of this review, which covers clinical and preclinical studies, is to highlight those peripheral and central mechanisms responsible for cancer pain. The challenges facing neuroscientists and clinicians studying and ultimately treating cancer pain are discussed. PMID:24664352

    2014-01-01

    Objectives This study aims to describe what adults with chronic pain experience in their role as parents, utilizing quantitative and qualitative methods. The first aim is to compare parents with chronic pain to parents without chronic pain on perceptions of their adolescent’s pain, parental response to pain, and catastrophizing beliefs about pain. The study also examined predictors of parental protective behaviors, and examined whether these associations differed by study group. Methods Parents with chronic pain (n=58) and parents without chronic pain (n=72) participated, and completed questionnaire measures of pain characteristics and pain interference, as well as measures of parental catastrophizing and protective pain responses. Parents with chronic pain also completed a structured interview about their experience of being a parent. Interview responses were videotaped and subsequently coded for content. Results Compared to controls, parents with chronic pain endorsed more pain in their adolescents, and were more likely to catastrophize about their adolescent’s pain and respond with protective behaviors. Parent’s own pain interference and the perception of higher pain in their adolescent was associated with increased protective parenting in the chronic pain group. Qualitative coding revealed a number of areas of common impact of chronic pain on parenting. Discussion Chronic pain impacts everyday parenting activities and emotions, and impacts pain-specific parent responses that are known to be related to increased pain and pain catastrophizing in children and adolescents. Parents with chronic pain might benefit from interventions that address potential parenting difficulties, and might improve outcomes for their children. PMID:25232862

    This guideline provides recommendations for primary care providers who are prescribing opioids for chronic pain outside of active cancer treatment, palliative care, and end-of-life care. The guideline addresses: (a) when to initiate or continue opioids for chronic pain; (b) opioid selection, dosage, duration, follow-up, and discontinuation; and (c) assessing risk and addressing harms of opioid use. This guideline is intended to improve communication between providers and patients about the risks and benefits of opioid therapy for chronic pain, improve the safety and effectiveness of pain treatment, and reduce the risks associated with long-term opioid therapy, including abuse, dependence, overdose, and death (Dowell D, Haegerich TM, Chou R.

    2016-01-01

    Following the widespread use of mesh repairs, recurrence rates after inguinal hernia surgery have become acceptable and focus has shifted from recurrence to chronic pain. Although pain can be controlled with analgesics, chronic postsurgical pain is a major clinical problem, which can significantly influence the patient's quality of life. The rate of chronic pain after inguinal hernia mesh repair can reach 51.6%. The reasons for posthernioplasty chronic pain are often unclear. It has been linked to nerve injury and nerve entrapment, but there is also association between the rate of chronic pain and the type of mesh used for hernia repair. As there are >160 meshes available in the market, it is difficult to choose a mesh whose usage would result in the best outcome. Different mesh characteristics have been studied, among them weight of mesh has probably gained the most attention. The choice of adequate therapy for chronic groin pain after inguinal hernia repair is controversial. The European Hernia Society recommends that a multidisciplinary approach at a pain clinic should be considered for the treatment of chronic postoperative pain. Although surgical treatment of chronic posthernioplasty pain is limited because of the lack of relevant research data, resection of entrapped nerves, mesh removal in the case of mesh related pain or removal of fixation sutures can be beneficial for the patient with severe pain after inguinal hernia surgery. One drawback of published studies is the lack of consensus over definition of chronic pain, which makes it complicated to compare the results of different studies and to conduct meta-analyses and systematic reviews. Therefore, a uniform definition of chronic pain and its best assessment methods should be developed in order to conduct top quality multicenter randomized trials. Further research to develop meshes with optimal parameters is of vital importance and should be encouraged. PMID:26567717

    Purpose There is evidence that the management of chronic non-cancer pain (CNCP) in primary care is far from being optimal. A 1-day workshop was held to explore the perceptions of key actors regarding the challenges and priority interventions to improve CNCP management in primary care. Methods Using the Chronic Care Model as a conceptual framework, physicians (n=6), pharmacists (n=6), nurses (n=6), physiotherapists (n=6), psychologists (n=6), pain specialists (n=6), patients (n=3), family members (n=3), decision makers and managers (n=4), and pain researchers (n=7) took part in seven focus groups and five nominal groups. Results Challenges identified in focus group discussions were related to five dimensions: knowledge gap, “work in silos”, lack of awareness that CNCP represents an important clinical problem, difficulties in access to health professionals and services, and patient empowerment needs. Based on the nominal group discussions, the following priority interventions were identified: interdisciplinary continuing education, interdisciplinary treatment approach, regional expert leadership, creation and definition of care paths, and patient education programs. Conclusion Barriers to optimal management of CNCP in primary care are numerous. Improving its management cannot be envisioned without considering multifaceted interventions targeting several dimensions of the Chronic Care Model and focusing on both clinicians and patients.

    Chronic pain in incarcerated women is understudied and poorly described. Study objectives were to describe pain characteristics, correlates, and predictors in a convenience sample of incarcerated women with chronic pain. A survey packet that included the Brief Pain Inventory Short Form (BPI-SF) and the Pain Catastrophizing Scale (PCS) was distributed to all inmates at a state prison for women. Those who self-identified as having chronic pain ≥4 on a 0-10 numeric rating scale were invited to complete the survey. Demographics and medical and psychiatric diagnoses were abstracted by chart review. Participants (N=159) rated their current and average pain intensity as severe. Pain catastrophizing was found to predict average pain intensity and level of pain-related interference in functioning. Pain catastrophizing is treatable with behavioral intervention in the general population. Findings suggest that pain catastrophizing may be an important target for research and treatment in incarcerated women with chronic pain. PMID:22643606

    2015-07-01

    Hydrocodone bitartrate is the most commonly used drug for acute and chronic pain in the U.S. with over 135 million prescriptions in 2012. The U.S. is the primary consumer of hydrocodone, using 99% of the global supply for 4.4% of the global population. With its easy availability and abuse patterns, hydrocodone has been touted as a primary driver of opioid-related abuse and misuse. There are no clinical efficacy studies of hydrocodone in short-acting form in combination with acetaminophen or ibuprofen in chronic pain. Hydrocodone has been approved with two long-term formulations since 2014. The FDA has rescheduled hydrocodone from Schedule III to Schedule II which went into effect on October 6, 2014, along with a limit on added acetaminophen of 325 mg for each dose of hydrocodone. This review examines the evolution of hydrocodone into a common and yet controversial drug in the U.S. with its pharmacokinetics, pharmacodynamics, safety and efficacy. PMID:26261844

    Intense abdominal pain is a prominent feature of chronic pancreatitis and its treatment remains a major clinical challenge. Basic studies of pancreatic nerves and experimental human pain research have provided evidence that pain processing is abnormal in these patients and in many cases resembles that seen in neuropathic and chronic pain disorders. An important ultimate outcome of such aberrant pain processing is that once the disease has advanced and the pathophysiological processes are firmly established, the generation of pain can become self-perpetuating and independent of the initial peripheral nociceptive drive. Consequently, the management of pain by traditional methods based on nociceptive deafferentation (e.g., surgery and visceral nerve blockade) becomes difficult and often ineffective. This novel and improved understanding of pain aetiology requires a paradigm shift in pain management of chronic pancreatitis. Modern mechanism based pain treatments taking into account altered pain processing are likely to increasingly replace invasive therapies targeting the nociceptive source, which should be reserved for special and carefully selected cases. In this review, we offer an overview of the current available pharmacological options for pain management in chronic pancreatitis. In addition, future options for pain management are discussed with special emphasis on personalized pain medicine and multidisciplinarity. PMID:24259960

    Pain in the spine is the most frequently described pain problem in primary care, afflicting at least 54 million Americans. When spinal pain becomes chronic, the prognosis for recovery is poor, often leading to disability and reduced quality of life. Clinical treatment is inadequate, often focusing on physical pathology alone. To improve treatment outcomes for chronic pain as recommended by current guidelines, the Biobehavioral Pain Profile (BPP), which includes six pain response subscales, was developed to guide cognitive behavioral therapy (CBT). The purpose of this study was to describe the BPP in 100 individuals with chronic spine pain and examine the associations between the BPP and important clinical outcomes, including chronic pain, disability, and quality of life. Participants reported a high level of pain, a low quality of life, and a high level of disability despite receiving treatment with opioids. Scores on BPP subscales including evaluating loss of control, past and current experience, physiologic responsivity, and thoughts of disease progression were elevated, indicating a need for CBT. Five of the six BPP subscales had a significant association with quality of life, chronic pain, and disability with the thought of disease progression being a strong factor for most of the clinical outcome variables. By identifying BPP, clinicians can provide appropriate treatments to improve individuals' quality of life and prevent further disability. Further study using the BPP to guide CBT is needed.

    This study examines retrospectively the cause, clinical features, natural history and results of treatment of intractable pain associated with breast cancer in 210 patients. The three chief types of pain were that due to skeletal metastases or brachial plexus neuropathy and pain of psychogenic origin. Onset at the time of cancer diagnosis characterized the psychogenic pain, whereas pain from metastases first occurred after a median latency of 3.7 years. Treatment was custom-tailored to the specific patient and pain problem, with several factors taken into account. The onset of intractable pain due to metastatic disease indicated a short survival (median, 9 months). PMID:6277445

    One of the major problems in modern medicine is to find remedies for the group of people with chronic pain syndromes. Low back pain is one of the most frequent syndromes and perhaps the most invalidating of all of them. Chronic pain seems to develop through several pathways affecting the spinal cord and the brain: (1) neuro-anatomical reorganisation, (2) neuro-physiological changes, and (3) activation of glia cells (immune reaction in the central nervous system). Although all of these pathways seem to provide a (partial) plausible explanation for chronic pain, treatments influencing these pathways often fail to alleviate chronic pain patients. This could be because of the probability that chronic pain develops by all three mechanisms of disease. A treatment influencing just one of these mechanisms can only be partially successful. Other factors that seem to contribute to the development of chronic pain are psychosocial. Fear, attention and anxiety are part of the chronic pain syndrome being cause or consequence. The three pathways and the psycho-emotional factors constitute a psycho-neuro-immunological substrate for chronic pain syndromes; a substrate which resembles the substrate for phantom pain and functional invalidity after stroke. Both phantom pain and functional invalidity are considered non-use syndromes. The similarity of the substrate of both these two neurological disorders and chronic pain makes it reasonable to consider chronic pain a non-use disease (the hypothesis). To test this hypothesis, we developed a "paradoxal pain therapy". A therapy which combines the constraint induced movement therapy and strategies to dissociate pain from conditioning factors like fear, anxiety and attention. The aim of the therapy is to establish a behaviour perpendicular on the pathological pain-behaviour. Clinically, the treatment seems promising, although we just have preliminary results. Further clinical and laboratory studies are needed to measure eventual changes at

    A survey conducted by the National Sleep Foundation found that 20% of Americans have sleep disorders and 45% experience chronic pain. Several authors evaluated the interrelationship between these functions using various instruments such the Pittsburgh Sleep Quality Index (PSQI) and identified that 34% of subjects in the general population have a poor quality of sleep, but there are few studies that assess the quality of sleep in patients with chronic pain of nonmalignant origin. We undertook this study to evaluate the quality of sleep using the PSQI in patients with chronic pain unrelated to cancer. We conducted a clinical, nonrandomized, uncontrolled, descriptive, and prospective study, applying the PSQI through a direct one-time interview to 311 subjects with chronic pain unrelated to cancer. According to the categorization of the PSQI between good and poor sleepers, 89% of the subjects were poor sleepers (n = 276). There are significant differences in pain intensity according to the categorization of the PSQI, with a higher intensity shown in the "poor sleepers" (analysis of variance [ANOVA], P = .030). Using a linear regression model to estimate the curve, a higher score is rated on the PSQI global score (ANOVA, P = .000, R(2) = .46) with the increase of the intensity of the pain. We conclude that "poor sleepers" or those who considered their sleep as "poor quality" have significantly higher pain intensity. This suggests that intensity of pain plays a role in evaluating the quality of sleep in the subjective perception of sleep and instruments that assess quality. PMID:24004315

    Background Long-acting opioid formulations are advocated for maintaining pain control in chronic cancer pain. OROS® hydromorphone is a sustained-release formulation of hydromorphone that requires dosing once daily to maintain therapeutic concentrations. The objective of this study was to demonstrate the clinical equivalence of immediate-release and sustained-release formulations of hydromorphone and morphine for chronic cancer pain. Methods 200 patients with cancer pain (requiring ≤ 540 mg/d of oral morphine) participated in this double-blind, parallel-group trial. Patients were randomized to receive hydromorphone or morphine (immediate-release for 2–9 days, sustained-release for 10–15 days). Efficacy was assessed with the Brief Pain Inventory (BPI), investigator and patient global evaluations, Eastern Cooperative Oncology Group performance status, and the Mini-Mental State Examination. The primary endpoint was the 'worst pain in the past 24 hours' item of the BPI, in both the immediate-release and sustained-release study phases, with treatments deemed equivalent if the 95% confidence intervals (CI) of the between-group differences at endpoint were between -1.5 and 1.5. No equivalence limits were defined for secondary endpoints. Results Least-squares mean differences (95% CI) between groups were 0.2 (-0.4, 0.9) in the immediate-release phase and -0.8 (-1.6, -0.01) in the sustained-release phase (intent-to-treat population), indicating that the immediate-release formulations met the pre-specified equivalence criteria, but that the lower limit of the 95% CI (-1.6) was outside the boundary (-1.5) for the sustained-release formulations. BPI 'pain now PM' was significantly lower with OROS® hydromorphone compared with controlled-release morphine (least-squares mean difference [95% CI], -0.77 [-1.49, -0.05]; p = 0.0372). Scores for other secondary efficacy variables were similar between the two sustained-release treatments. At endpoint, > 70% of investigators and

    In the United States, millions of Americans are affected by chronic pain, which adds heavily to national rates of morbidity, mortality, and disability, with an ever-increasing prevalence. According to a 2011 report titled Relieving Pain in America: A Blueprint for Transforming Prevention, Care, Education, and Research by the Institute of Medicine of the National Academies, pain not only exacts its toll on people's lives but also on the economy with an estimated annual economic cost of at least $560 - 635 billion in health care costs and the cost of lost productivity attributed to chronic pain. Intravenous infusions of certain pharmacologic agents have been known to provide substantial pain relief in patients with various chronic painful conditions. Some of these infusions are better, and although not necessarily the first therapeutic choice, have been widely used and extensively studied. The others show promise, however are in need of further investigations. This article will focus on non-opiate intravenous infusions that have been utilized for chronic painful disorders such as fibromyalgia, neuropathic pain, phantom limb pain, post-herpetic neuralgia, complex regional pain syndromes (CRPS), diabetic neuropathy, and central pain related to stroke or spinal cord injuries. The management of patients with chronic pain conditions is challenging and continues to evolve as new treatment modalities are explored and tested. The following intravenous infusions used to treat the aforementioned chronic pain conditions will be reviewed: lidocaine, ketamine, phentolamine, dexmedetomidine, and bisphosphonates. This overview is intended to familiarize the practitioner with the variety of infusions for patients with chronic pain. It will not, however, be able to provide guidelines for their use due to the lack of sufficient evidence. PMID:23703410

    Approximately 10% of patients following a variety of surgeries develop chronic postsurgical pain. Reducing chronic postoperative pain is especially important to reconstructive surgeons because common operations such as breast and limb reconstruction have even higher risk for developing chronic postsurgical pain. Animal studies of posttraumatic nerve injury pain demonstrate that there is a critical time frame before and immediately after nerve injury in which specific interventions can reduce the incidence and intensity of chronic neuropathic pain behaviors–so called “preventative analgesia.” In animal models, perineural local anesthetic, systemic intravenous local anesthetic, perineural clonidine, systemic gabapentin, systemic tricyclic antidepressants, and minocycline have each been shown to reduce pain behaviors days to weeks after treatment. The translation of this work to humans also suggests that brief perioperative interventions may protect patients from developing new chronic postsurgical pain. Recent clinical trial data show that there is an opportunity during the perioperative period to dramatically reduce the incidence and severity of chronic postsurgical pain. The surgeon, working with the anesthesiologist, has the ability to modify both early and chronic postoperative pain by implementing an evidence-based preventative analgesia plan. PMID:23463498

    Background Despite current advances in cancer treatment, many breast cancer survivors still face long-term post-operative challenges as a result of suffering from daily pain and other distressing symptoms related to lymphedema, ie, abnormal accumulation of lymph fluid in the ipsilateral upper limb or body. Grounded in research-driven behavioral strategies, The-Optimal-Lymph-Flow is a unique Web- and mobile-based system focusing on self-care strategies to empower, rather than inhibit, how breast cancer survivors manage daily pain and symptoms. It features a set of safe, feasible, and easily-integrated-into-daily-routine exercises to promote lymph flow and drainage, as well as guidance to maintain an optimal body mass index (BMI). Objective To conduct a randomized clinical trial (RCT) to evaluate the efficacy of the Web- and mobile-based The-Optimal-Lymph-Flow system for managing chronic pain and symptoms related to lymphedema. The primary outcome includes pain reduction, and the secondary outcomes focus on symptom relief, limb volume difference by infra-red perometer, BMI, and quality of life (QOL) related to pain. We hypothesize that participants in the intervention group will have improved pain and symptom experiences, limb volume difference, body mass index, and QOL. Methods A parallel RCT with a control-experimental, pre- and post-test, repeated-measures design is used in this study. A total of 120 patients will be randomized according to the occurrence of pain. Participants will be recruited face-to-face at the point of care during clinical visits. Participants in the intervention group will receive the Web- and mobile-based The-Optimal-Lymph-Flow intervention and will have access to and learn about the program during the first in-person research visit.

    Objectives Use of prescription opioids for chronic pain is increasing, as is abuse of these medications, though the nature of the link between these trends is unclear. These increases may be most marked in patients with mental health (MH) and substance use disorders (SUDs). We analyzed trends between 2000 and 2005 in opioid prescribing among individuals with non-cancer pain conditions (NCPC), with and without MH and SUDs. Methods Secondary data analysis of longitudinal administrative data from two dissimilar populations: a national, commercially-insured population, and Arkansas Medicaid enrollees. We examined these opioid outcomes: (1) Rates of any prescription opioid use in the past year, (2) rates of chronic use of prescription opioids (greater than 90 days in the past year), (3) mean days supply of opioids, (4) mean daily opioid dose in morphine equivalents, and (5) percentage of total opioid dose that was Schedule II opioids. Results In 2000, among individuals with NCPC, chronic opioid use was more common among those with a MH or SUD than those without in commercially insured (8% versus 3%, p<0.001) and Arkansas Medicaid (20% versus 13%, p<0.001). Between 2000 and 2005, in commercially insured, rates of chronic opioid use increased by 34.9% among individuals with an MH or SUD, and 27.8% among individuals without these disorders. In Arkansas Medicaid chronic opioid use increased 55.4% among individuals with an MH or SUD, and 39.8% among those without. Discussion Chronic use of prescription opioids for NCPC is much higher and growing faster in patients with MH and SUDs than those without these diagnoses. Clinicians should monitor use of prescription opioids in these vulnerable groups to determine whether opioids are substituting for or interfering with appropriate mental health and substance abuse treatment.

    The pattern and frequency of neurovegetative symptoms was studied in 57 patients with chronic pain. Seventy-nine percent of these patients had a diagnosable depressive illness, but endogenous depression was rare (5%). Patients with chronic pain were divided into major depressives, minor/intermittent depressives and patients with no depression. A control group of nonendogenous major depressives without pain was also utilized. Major depressives differed from the other two chronic pain groups in that there was more frequent or severe early waking, weight loss, anorexia, diminished libido and initial insomnia. Diurnal variation of mood was not a characteristic of major depression with chronic pain, and did not differ in frequency from the other two chronic pain groups. Major depressives exhibited a profile of neurovegetative symptoms very similar to that found in the control group of major depressives. Over one-third of minor/intermittent depressed patients with chronic pain exhibited atypical (reversed) vegetative symptoms of hyperphagia and weight gain. This finding, together with our review of the literature, suggests an important and previously unrecognized link between atypical depression and chronic pain. PMID:2934454

    Several empirical studies have shown that personal characteristics act as differential variables, which determine how pain is experienced and how the chronic pain patient adjusts to pain. The main aim of the present research is to review the relationships between some dispositional characteristics and pain adjustment. Taking into account the empirical literature, 6 personality traits that are relevant to the pain experience have been selected: neuroticism, anxiety sensitivity, and experiential avoidance as risk factors that increase the probability of patients experiencing a disability; and extraversion, optimism, and resilience as personal resources that increase their capacity to manage pain effectively. The results suggest that it would be useful to include an assessment of normal personality structure during the multi-dimensional evaluation of a person with chronic pain. Understanding these individual personality characteristics will aid in designing pain intervention programs and help predict possible treatment outcomes. PMID:23338768

In line with their increased use, both of these approaches have exponentially gathered increasing evidence to support their use.4,10 For example, various randomised controlled trials and systematic reviews have shown that teaching patients more about the biology and physiology of their pain experience leads to positive changes in pain, pain catastrophization, function, physical movement and healthcare utilisation.7–10 Graded motor imagery, in turn, has shown increasing evidence to help pain and disability in complex pain states such as complex regional pain syndrome (CRPS).11,12 Most research using TNE and GMI has focussed on chronic low back pain (CLBP) and CRPS and none of these advanced pain treatments have been trialled on the thoracic spine.

    Pain is a significant burden for patients with cancer and is particularly prevalent among those with advanced cancer. Appropriate interventional cancer pain therapies complement conventional pain management by reducing the need for systemic opioid therapy and its associated toxicity; however, these therapies are often underutilized. This article reviews techniques, indications, complications, and outcomes of the most common interventional approaches for the management of cancer-related pain. These approaches include intrathecal drug delivery, vertebral augmentation, neurolysis of the celiac, superior hypogastric and ganglion impar plexus', image-guided tumor ablation, and other less commonly performed but potentially beneficial interventions.

    2015-10-01

    Chronic pelvic pain is defined as disabling pain of at least six months duration. Chronic pelvic pain has often multiple causative factors. Careful analysis of clinical history and detailed clinical examination must be carried out to guide further imaging investigations. Endometriosis is a common cause of chronic pelvic pain, although there is no correlation between the severity of lesions and pain intensity. Pelvic ultrasonography should be the first line imaging examination to search for causative conditions that include endometriosis, adenomyosis, pelvic varices and chronic infection. Magnetic resonance imaging (MRI) is useful for making the positive diagnosis and assessing the spread of endometriosis. MRI is more accurate than ultrasonography for the diagnosis of tubo-ovarian abscess when an adnexal mass is identified. Duplex and color Doppler ultrasonography as well as MR angiography are the best imaging technique for the diagnosis of pelvic congestion syndrome. In patients with pudendal neuralgia, cross-sectional imaging help exclude nerve compression. PMID:26441020

    PubMed

    Compton, Peggy; Athanasos, Peter

    2003-09-01

    Health care professionals face numerous challenges in assessing and treating chronic pain patients with a substance abuse history. Societal perspectives on morality and criminality, imprecise addiction terminology, litigation fears, and genuine concern for a patient's relapse into or escalation of substance abuse result in unrelieved and under-relieved pain in precisely the population that--as increasing evidence indicates--is generally intolerant of pain. Before adequate pain relief can occur in chronic pain patients with current or past substance abuse issues, it is imperative that the clinician recognize addiction as a disease with known symptoms and treatments. Further, the clinician must realize the difference between true addiction and similar conditions, so the patient's condition can be monitored and regulated properly. Although clinicians are often reluctant to medicate with opioids, it is always best to err on the side of adequate pain relief. Withholding opioids from chronic pain patients in order to avoid the onset or relapse of addiction is contrary to the growing body of evidence and results only in unnecessary pain for the patient. Chronic pain in patients with a history of addictive disease can be treated successfully with opiate analgesia; it just requires caution and careful monitoring of medication use. If addiction is treated as a known risk when providing opioid analgesia to a recovering addict, its development can be minimized while pain relief is provided. PMID:14567207

    Deep brain stimulation (DBS) is a commonly performed procedure and has been used for the treatment of chronic pain since the early 1970s. A review of the literature was performed utilizing the PubMed database evaluating the use of DBS in the treatment of various pain syndromes. Literature over the last 30 years was included with a focus on those articles in the last 10 years dealing with pain conditions with the highest success as well as the targets utilized for treatment. DBS carries favorable results for the treatment of chronic pain, especially when other methods have not been successful such as medications, conservative measures, and extracranial procedures. Various chronic pain conditions reported in the literature respond to DBS including failed back surgery syndrome (FBSS), phantom limb pain, and peripheral neuropathic pain with a higher response rate for those with nociceptive pain compared to neuropathic pain. Cephaligias have promising results, with cluster headaches carrying the best success rates. DBS plays a role in the treatment of chronic pain conditions. Although considered investigational in the USA, it carries promising success rates in a recalcitrant patient population. PMID:26049773

    2013-01-01

    Objective This study aimed to examine the association of hemiplegic shoulder pain with central hypersensitivity through pressure-pain thresholds (PPT) at healthy, distant tissues. Design This study is a cross-sectional study. A total of 40 patients (n=20 hemiplegic shoulder pain (HSP), n=20 stroke without HSP) were enrolled in this study. Pressure-pain thresholds were measured at the affected deltoid and contralateral deltoid and tibialis anterior using a handheld algometer. Differences in PPTs were analyzed by Wilcoxon Rank Sum test and with linear regression analysis controlling for gender, a known confounder of PPTs. Results Subjects with hemiplegic shoulder pain had lower local PPTs than stroke control subjects when comparing the painful to dominant shoulders and comparing the non-painful shoulder and tibialis anterior to the non-dominant side controls. Similarly, those with hemiplegic shoulder pain had lower PPTs when comparing to controls in contralesional-to-contralesional comparisons as well as ipsilesional-to-ipsilesional comparisons. Conclusions Subjects with hemiplegic shoulder pain have lower local and distal PPTs than subjects without hemiplegic shoulder pain. Our study suggests that chronic shoulder pain may be associated with widespread central hypersensitivity, which has been previously found to be associated with other chronic pain syndromes. This further understanding can then help develop better treatment options for those with this hemiplegic shoulder pain. PMID:23255268

    Summary Co-occurring substance use disorders (SUDs) are common among chronic pain patients. However, limited data are available to guide treatment for chronic pain patients with SUD. Recent data suggest that comorbid substance use disorders (SUDs) are common among chronic non-cancer pain (CNCP) patients; however, prevalence rates vary across studies and findings are limited regarding treatment options for CNCP patients with comorbid SUD. The purpose of this systematic review is to assess the prevalence, associated demographic and clinical characteristics, and treatment outcomes for CNCP patients with comorbid SUD. We conducted searches from Ovid MEDLINE, PsychINFO, and PubMED from 1950 through February 2010 and retrieved the references. Thirty-eight studies met inclusion criteria and provided data that addressed our key questions. Three to forty-eight percent of CNCP patients have a current SUD. There are no demographic or clinical factors that consistently differentiate CNCP patients with comorbid SUD from patients without SUD, though SUD patients appear to be at greater risk for aberrant medication-related behaviors. CNCP patients with SUD are more likely to be prescribed opioid medications and at higher doses than CNCP patients without a history of SUD. CNCP patients with comorbid SUD do not significantly differ in their responses to treatment compared to CNCP patients without SUD, though the quality of this evidence is low. Limited data are available to identify predictors of treatment outcome. Although clinical experience and research suggests that SUDs are common among CNCP patients, only limited data are available to guide clinicians who treat this population. Research is needed to increase understanding of the prevalence, correlates, and responses to treatment of CNCP patients with comorbid SUDs. PMID:21185119

    Neuropathic pain is a significant social and economic burden. Back pain, joint pain and headaches affect over 30% of the population. Chronic orofacial pain is a common condition and is difficult to diagnose and manage. This two-part paper aims to provide an overview of novel understanding of neuropathic pain, and furnish clinical teams with an update on the less common and less well-recognized chronic orofacial conditions. Headaches and temporomandibular disorders are the most common conditions and are covered in separate papers (6 and 10). Trigeminal neuralgia, burning mouth, and trigeminal autonomic cephalgias are also covered in separate papers (7, 8 and 9). The remaining conditions: post-traumatic neuropathy (nerve injury); and persistent idiopathic facial pain and atypical odontalgia are discussed in this and the following paper. Clinical Relevance: Neuropathic pain, though rare, is a consequence of dental treatment. Nerve injury in relation to M3M surgery, dental implants, endodontics and local anaesthesia result in 70% of affected patients experiencing chronic neuropathic pain. PMID:26685473

    Low back pain is an extremely common presenting complaint that occurs in upward of 80% of persons. Treatment of an acute episode of back pain includes relative rest, activity modification, nonsteroidal anti-inflammatories, and physical therapy. Patient education is also imperative, as these patients are at risk for further future episodes of back pain. Chronic back pain (>6 months' duration) develops in a small percentage of patients. Clinicians' ability to diagnose the exact pathologic source of these symptoms is severely limited, making a cure unlikely. Treatment of these patients should be supportive, the goal being to improve pain and function. PMID:26614726

    The literature on methods of invasive local treatment of chronic pain was analyzed. We reviewed 14 publications including meta-analyses and systematic reviews. The use of regional anesthesia conducted by anesthesiologists in pain clinics demonstrated the evidence based efficacy of different types of peridural injections of local anesthetics with steroids in patients with root pain syndromes at cervical and lumbar levels. Therapeutic blockades of the occipital nerve is effective method of treatment of cervicogenic and cluster headache as well as occipital nerve neuralgia. There are clear indications of the efficacy of local injections in primary chronic cephalgia (migraine and headache of tension). The possibility of the abortion of the pain information flow in peripheral nociceptive pathways and, as a consequence, breaking the vicious circle is emphasized. Issues on the efficacy of local injections at trigger points in the treatment of chronic pain are highlighted. PMID:24874319

    Foot pain is a common accompaniment of advancing age, affecting at least one in four older people. However, management of foot pain is a largely undervalued aspect of geriatric health care, resulting in many older people needlessly enduring chronic foot pain and related disability. The aim of this review is to provide an overview of (i) the prevalence and risk factors for foot pain, (ii) the impact of foot pain on mobility and quality of life, and (iii) the conservative management of foot pain. The available evidence indicates that although foot pain is common and disabling in older people, conservative interventions such as routine foot care, footwear advice and foot orthoses are effective at reducing foot pain and may also assist in maintaining mobility and independence in this age group.

    Chronic pain represents a challenge to patients, families, employers, and the physicians who care for these individuals. Opioids remain the mainstay of the analgesic medications for the treatment of both acute and chronic pain. Controlled release preparations of morphine, oxycodone, fentanyl and long acting opioid agents such as methadone and levorphanol have been medically and ethically accepted in managing chronic cancer pain. However, the continued use of these medications for patients with chronic noncancer pain has been fiercely debated. This article attempts to reconcile the medical and ethical dilemma of using opioid medications for chronic noncancer pain. Growing clinical experience in the field of pain medicine has helped to clarify: (1) the misunderstanding of addiction, physical dependence and analgesic tolerance, (2) the misconception that chronic opioid therapy inevitably causes personality changes, depression, and impairment of cognitive and physical function, (3) the lack of information on the correct use of opioid analgesics with regard to titration and management of related side effects. The behavioral management of pain patients undergoing chronic opioid therapy is also discussed. A protocol for optimal patient management is proposed. Particular emphasis is given to the consent form, behavioral contracting, and the consequences of noncompliance. The importance of psychologic evaluation before a long-term opioid trial, to minimize future complications, is stressed. Although most patients on the opioid regimen do well, special attention must be given to patients with current addiction, a past history of addiction, or current misuse of opioid medications. Pharmacologic and conservative interventions are often warranted in those patients with significant behavioral problems. If such strategies fail, and chronic opioid therapy is deemed necessary, some treatment guidelines are offered. PMID:9311061

    2016-01-01

    Introduction: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and interstitial cystitis/bladder pain syndrome collectively referred to as urologic CPPS (UCPPS) is defined by the absence of identifiable bacterial infection as a cause for the chronic pain and urinary symptoms. Methods: A PubMed search of all recent relevant articles using the keywords/phrases: CPPS, CPPS, and male pelvic pain, was conducted. Results: CPPS has a high worldwide prevalence and its negative impact on quality of life compares with or exceeds common chronic morbidities. Triggers include certain comestibles as well as psychosocial factors that promote catastrophizing and illness focused behavior. Several validated tools are currently available to help diagnose and direct targeted therapy. Treatment should begin with the most simple and least invasive based on the presenting clinical phenotype. Conclusions: Although no gold-standard treatment exists, a multidisciplinary approach with multimodal therapy gives the UCPPS patient the best chance of symptom relief. PMID:26941492

    Context: Psychological factors, such as that exist when we experience pain, can profoundly alter the strength of pain perception. Aim: The study aims to estimate the prevalence of psychiatric disorders, and its association with perception of pain and functional status in chronic patients in palliative care. Materials and Methods: The sample was selected via simple randomisation and post consent were assessed using (1) a semi- structured questionnaire to elicit socio-demographic information and medical data (2) Brief Pain Inventory (3) ICD-10 Symptom Checklist (4) ICD-10-Diagnostic Criteria for Research (DCR) (5) Montgomery Asberg Depression Rating Scale (MADRS) (6) Covi Anxiety Rating Scale (7) Karnofsky Performance Status Scale. Data was analysed using independent sample t test and chi square test. Results: The psychiatric morbidity was 67% with depression and adjustment disorders being the major diagnosis. There was a significant association between psychiatric morbidity pain variables (P = 0.000). Psychiatric morbidity significantly impaired activity, mood, working, walk, sleep, relationship, and enjoyment. There was no association between aetiology of pain, type of cancer, treatment for primary condition and treatment for pain and psychiatric morbidity. The functional status of cancer patients was also poorer in patients with psychiatric morbidity (P = 0.008). Conclusion: There is a high prevalence of psychiatric illness in chronic pain patients of any aetiology. Psychiatric morbidity is associated with increased pain perception, impairment in activity and poor functional status. PMID:24347904

    Objective: The aim of this study was to assess safety and efficacy of fixed combination oxycodone prolonged release (PR)/naloxone PR in terms of both analgesia and improving opioid-induced bowel dysfunction (OIBD) and associated symptoms, such as opioid-induced constipation (OIC), in adults with chronic non-cancer pain. Study design: These were open-label extension studies in which patients who had previously completed a 12-week, double-blind study received oxycodone PR/naloxone PR for up to 52 weeks. The analgesia study assessed pain using the modified Brief Pain Inventory-Short Form (BPI-SF). The bowel function study assessed improvements in constipation using the Bowel Function Index (BFI). Results: At open-label baseline in the analgesia study (n = 379), mean score [± standard deviation (SD)] for the BPI-SF item ‘average pain over the last 24 h’ was 3.9 ± 1.52, and this remained low at 6 months (3.7 ± 1.59) and 12 months (3.8 ± 1.72). Mean scores for BPI-SF item ‘sleep interference’, and the BPI-SF ‘pain’ and ‘interference with activities’ subscales also remained low throughout the 52-week study. In the bowel function study (n = 258), mean BFI score (± SD) decreased from 35.6 ± 27.74 at the start of the extension study to 20.6 ± 24.01 after 12 months of treatment with oxycodone PR/naloxone PR. Pain scores also remained low and stable during this study. Adverse events in both extension phases were consistent with those associated with opioid therapy; no additional safety concerns were observed. Conclusion: Results from these two open-label extension studies demonstrate the long-term efficacy and tolerability of fixed combination oxycodone PR/naloxone PR in the treatment of chronic pain. Patients experienced clinically relevant improvements in OIBD while receiving effective analgesic therapy. PMID:20370845

    There is emerging evidence that chronic musculoskeletal pain is associated with anatomical and functional abnormalities in gray matter. However, little research has investigated the relationship between chronic musculoskeletal pain and white matter (WM). In this study, we used whole-brain tract-based spatial statistics, and region-of-interest analyses of diffusion tensor imaging (DTI) data to demonstrate that patients with chronic musculoskeletal pain exhibit several abnormal WM integrity as compared to healthy controls. Chronic musculoskeletal pain was associated with lower fractional anisotropy (FA) in the splenium of corpus callosum, and left cingulum adjacent to the hippocampus. Patients also had higher radial diffusivity (RD) in the splenium, right anterior and posterior limbs of internal capsule, external capsule, superior longitudinal fasciculus, and cerebral peduncle. Patterns of axial diffusivity (AD) varied: patients exhibited lower AD in the left cingulum adjacent to the hippocampus and higher AD bilaterally in the anterior limbs of internal capsule, and in the right cerebral peduncle. Several correlations between diffusion metrics and clinical variables were also significant at a p<0.01 level: FA in the left uncinate fasciculus correlated positively with Total Pain Experience and typical levels of pain severity. AD in the left anterior limb of internal capsule and left uncinate fasciculus were correlated with Total Pain Experience and typical pain level. Positive correlations were also found between AD in the right uncinate and both Total Pain Experience and Pain Catastrophizing. These results demonstrate that WM abnormalities play a role in chronic musculoskeletal pain; either as a cause, predisposing factor, consequence, or compensatory adaptation. PMID:25135468

    More than 30% of U.S. adults report having experienced low back pain within the preceding three months. Although most low back pain is nonspecific and self-limiting, a subset of patients develop chronic low back pain, defined as persistent symptoms for longer than three months. Low back pain is categorized as nonspecific low back pain without radiculopathy, low back pain with radicular symptoms, or secondary low back pain with a spinal cause. Imaging should be reserved for patients with red flags for cauda equina syndrome, recent trauma, risk of infection, or when warranted before treatment (e.g., surgical, interventional). Prompt recognition of cauda equina syndrome is critical. Patient education should be combined with evidence-guided pharmacologic therapy. Goals of therapy include reducing the severity of pain symptoms, pain interference, and disability, as well as maximizing activity. Validated tools such as the Oswestry Disability Index can help assess symptom severity and functional change in patients with chronic low back pain. Epidural steroid injections do not improve pain or disability in patients with spinal stenosis. Spinal manipulation therapy produces small benefits for up to six months. Because long-term data are lacking for spinal surgery, patient education about realistic outcome expectations is essential. PMID:25978200

    A child or adolescent can suffer from chronic pain. Whatever the causes, it can trap the child in a specific process whereby they focus on the pain, fearing that it will appear and experiencing anxiety. Hypno-analgesia and hypnotherapy enable them to escape this process and find within themselves the capacity to face up to the pain. Moreover, these techniques offer them an autonomy which they can use in all areas of their life. PMID:24779171

    The aims of this study were to investigate the prevalence of orofacial pain symptoms in the Korean elderly population, and to evaluate factors associated with orofacial pain and graded chronic pain. Of 4,342 Korean elders from the cohort of Korean National Interview Survey of Oral Health Status in 2000, telephone interviews were conducted on a stratified random sample of 1,032 people aged 55 years or older. Prevalence of five orofacial pain symptoms (jaw joint pain, face pain, toothache, oral sores, and burning mouth) in the past 6 months along with questions from the graded chronic pain scale were assessed by telephone using a structured questionnaire. The results suggested that the 6-month prevalence of joint pain (15.5%), face pain (9.3%), toothache (26.8%), oral sores (26.2%), and burning mouth (14.2%) in Korean elders were higher than in studies on Caucasian populations. Painful oral sores and burning mouth had higher prevalence for females than for males. Subjects with joint pain, burning mouth or toothache pain were more likely to report high levels of a pain-related disability compared with subjects not reporting those symptoms. There were no age group differences in pain intensity, but the older age group reported a higher number of disability days because of their pain. Chronic orofacial pain is a substantial health problem in the elderly population. PMID:15494197

    Background. Chronic pain is associated with increased morbidity and mortality, predominated by cardiovascular disease and cancer. Investigating related risk factor measures may elucidate the biological burden of chronic pain. Objectives. We hypothesized that chronic pain severity would be positively associated with the risk factor composite. Methods. Data from 12,982 participants in the 6th Tromsø study were analyzed. Questionnaires included demographics, health behaviors, medical comorbidities, and chronic pain symptoms. The risk factor composite was comprised of body mass index, fibrinogen, C-reactive protein, and triglycerides. Chronic pain severity was characterized by frequency, intensity, time/duration, and total number of pain sites. Results. Individuals with chronic pain had a greater risk factor composite than individuals without chronic pain controlling for covariates and after excluding inflammation-related health conditions (p < 0.001). A significant "dose-response" relationship was demonstrated with pain severity (p < 0.001). In individuals with chronic pain, the risk factor composite varied by health behavior, exercise, lower levels and smoking, and higher levels. Discussion. The risk factor composite was higher in individuals with chronic pain, greater with increasing pain severity, and influenced by health behaviors. Conclusions. Identification of a biological composite sensitive to pain severity and adaptive/maladaptive behaviors would have significant clinical and research utility. PMID:27445627

    The differential diagnosis for chronic ankle pain is quite broad. Ankle pain can be caused by intra-articular or extra-articular pathology and may be a result of a traumatic or nontraumatic event. A detailed patient history and physical examination, coupled with judicious selection of the appropriate imaging modalities, are vital in making an accurate diagnosis and providing effective treatment. Chronic ankle pain can affect all age groups, ranging from young athletes to elderly patients with degenerative joint and soft-tissue disorders. It has been estimated that 23,000 ankle sprains occur each day in the United States, representing approximately 1 sprain per 10,000 people per day. Because nearly one in five ankle injuries result in chronic symptoms, orthopaedic surgeons are likely to see patients with chronic ankle pain. Many patients with chronic ankle pain do not recall any history of trauma. Reviewing the management of the various disorders that can cause chronic ankle pain will help orthopaedic surgeons provide the best treatment for their patients. PMID:21553785

    The neural mechanisms underlying the development and maintenance of chronic neuropathic pain remain unclear. Evidence from human investigations suggests that neuropathic pain is associated with altered thalamic burst firing and thalamocortical dysrhythmia. Additionally, experimental animal investigations show that neuropathic pain is associated with altered infra-slow (<0.1 Hz) frequency oscillations within the dorsal horn and somatosensory thalamus. The aim of this investigation was to determine whether, in humans, neuropathic pain was also associated with altered infra-slow oscillations within the ascending "pain" pathway. Using resting-state functional magnetic resonance imaging, we found that individuals with orofacial neuropathic pain have increased infra-slow oscillatory activity throughout the ascending pain pathway, including within the spinal trigeminal nucleus, somatosensory thalamus, thalamic reticular nucleus, and primary somatosensory cortex. Furthermore, these infra-slow oscillations were temporally coupled across these multiple sites and occurred at frequencies similar to calcium waves in activated astrocytes. The region encompassing the spinal trigeminal nucleus also displayed increased regional homogeneity, consistent with a local spread of neural activity by astrocyte activation. In contrast, no increase in oscillatory behavior within the ascending pain pathway occurred during acute noxious stimuli in healthy individuals. These data reveal increased oscillatory activity within the ascending pain pathway that likely underpins increased thalamocortical oscillatory activity, a self-sustaining thalamocortical dysrhythmia, and the constant perception of pain. Significance statement: Chronic neuropathic pain is associated with altered thalamic firing and thalamocortical dysrhythmia. The mechanisms responsible for these changes remain unknown. In this study, we report in individuals with neuropathic pain increased oscillatory neural activity within the

    This review aims at presenting a current view on the physiopathologic mechanisms associated with temporomandibular disorders (TMDs). While joint pain is characterized by a well-defined inflammatory process mediated by tumor necrosis factor-α and interleukin, chronic muscle pain presents with enigmatic physiopathologic mechanisms, being considered a functional pain syndrome similar to fibromyalgia, irritable bowel syndrome, interstitial cystitis and chronic fatigue syndrome. Central sensitization is the common factor unifying these conditions, and may be influenced by the autonomic nervous system and genetic polymorphisms. Thus, TMDs symptoms should be understood as a complex response which might get worse or improve depending on an individual's adaptation. PMID:25741834

    Obesity and pain present serious public health concerns in our society. Evidence strongly suggests that comorbid obesity is common in chronic pain conditions, and pain complaints are common in obese individuals. In this paper, we review the association between obesity and pain in the general population as well as chronic pain patients. We also review the relationship between obesity and pain response to noxious stimulation in animals and humans. Based upon the existing research, we present several potential mechanisms that may link the two phenomena, including mechanical/structural factors, chemical mediators, depression, sleep, and lifestyle. We discuss the clinical implications of obesity and pain, focusing on the effect of weight loss, both surgical and noninvasive, on pain. The literature suggests that the two conditions are significant comorbidities, adversely impacting each other. The nature of the relationship however is not likely to be direct, but many interacting factors appear to contribute. Weight loss for obese pain patients appears to be an important aspect of overall pain rehabilitation, although more efforts are needed to determine strategies to maintain long-term benefit.

    In the past decade there has been a dramatic increase in (1) understanding the neurophysiological components of the pain experiences, (2) randomized clinical trials testing the efficacy of hypnotic treatments on chronic pain, and (3) laboratory research examining the effects of hypnosis on the neurophysiological processes implicated in pain. Work done in these areas has not only demonstrated the efficacy of hypnosis for treating chronic pain but is beginning to shed light on neurophysiological processes that may play a role in its effectiveness. This paper reviews a selection of published studies from these areas of research, focusing on recent findings that have the most potential to inform both clinical work and research in this area. The paper concludes with research and clinical recommendations for maximizing treatment efficacy based on the research findings that are available. PMID:24073099

    Objective Increasing rates of opioid use disorders (abuse and dependence) among patients prescribed opioids are a significant public health concern. We investigated the association between exposure to prescription opioids and incident opioid use disorders (OUDs) among individuals with a new episode of a chronic non-cancer pain (CNCP) condition. Methods We utilized claims data from the HealthCore Database for 2000–2005. The dataset included all individuals aged 18 and over with a new CNCP episode (no diagnosis in the prior 6 months), and no opioid use or OUD in the prior 6 months (n=568,640). We constructed a single multinomial variable describing prescription opioid days supply (none, acute, and chronic) and average daily dose (none, low dose, medium dose, and high dose), and examined the association between this variable and an incident OUD diagnosis. Results Patients with CNCP prescribed opioids had significantly higher rates of OUDs compared to those not prescribed opioids. Effects varied by average daily dose and days supply: low dose, acute (odds ratio (OR)=3.03, 95% confidence interval (CI)= 2.32, 3.95); low dose, chronic (OR=14.92, 95% CI=10.38, 21.46); medium dose, acute (OR=2.80, 95% CI=2.12, 3.71); medium dose, chronic (OR=28.69, 95% CI=20.02, 41.13); high dose, acute (OR=3.10 95% CI=1.67, 5.77); and high dose, chronic (OR=122.45, 95% CI=72.79, 205.99). Conclusion Among individuals with a new CNCP episode, prescription opioid exposure was a strong risk factor for incident OUDs; magnitudes of effects were large. Duration of opioid therapy was more important than daily dose in determining OUD risk. PMID:24281273

    Background Concomitant use of opioids and promethazine has been reported in various subpopulations, including methadone maintenance patients, injection drug users, and at-risk teenagers. Promethazine is thought to potentiate the “high” from opioids. However, to date, the prevalence of promethazine use has not been determined among patients prescribed opioids for chronic pain. Methods Urine samples from 921 patients prescribed opioids for chronic pain were analyzed for promethazine. Demographic data, toxicology results, and opioid prescription information were obtained through medical record abstraction. We assessed the prevalence and factors associated with promethazine use with bivariable and multivariable statistics. Results The prevalence of promethazine-positive urine samples among chronic pain patients was 9%. Only 50% of promethazine-positive patients had an active prescription for promethazine. Having benzodiazepine-positive urine with no prescription for a benzodiazepine was statistically associated with promethazine use. Also, having a prescription for methadone for pain or being in methadone maintenance for the treatment of opioid dependence were both statistically associated with promethazine use. Chronic pain patients prescribed only a long-acting opioid were more likely to have promethazine-positive urines than patients prescribed a short-acting opioid. Conclusions The study provides compelling evidence of significant promethazine use in chronic pain patients. Promethazine should be considered as a potential drug of abuse that could cause increased morbidity in opioid-using populations. PMID:25754939

    Chronic low back pain (CLBP) is a significant healthcare problem, and many individuals with CLBP remain unresponsive to available interventions. Previous research suggests that hypnosis is effective for many chronic pain conditions; however, data to support its efficacy for CLBP are outdated and have been limited primarily to case studies. This pilot study indicated that a brief, 4-session standardized self-hypnosis protocol, combined with psycho-education, significantly and substantially reduced pain intensity and pain interference. Significant session-to-session improvements were also noted on pain ratings and mood states; however, follow-up data suggest that these benefits may not have been maintained across time in this sample. These findings need to be replicated and confirmed in a larger clinical trial, which could also assess the long-term effects of this treatment. PMID:20183738

    The aim of the study was to analyze the primary prevalence of chronic neuropathic pain syndrome in oncology patients of Karaganda (Kazakhstan), to estimate the structure of pain syndrome in randomly chosen patients, to assess the effectiveness of analgesic therapy in oncology patients. All the patients with confirmed cancer admitted to hospital in Karaganda regional oncologic dispensary were studied. The study period was limited to 60 consecutive days. The results were statistically processed using 6.0 «STATISTICA» program. In 11,2±1,6% of the cases, oncology patients that got combined modality treatment suffered from the chronic neuropathic pain syndrome; 66,7±7,3% patients of them had the III cancer stage. 2. While studying the chronic neuropathic pain structure it was revealed that: 52,4±7,7% of the patients suffered from a mild pain, from average - 38,1±7,5% of the patients, from severe pain - 9,5±4,5%. Neuropathic pain syndrome in the form of numbness occurred in 47,6±7,7% of the respondents, tingling - in 38,1±7,5% of the patients and 14,3±5,4% of the respondents described it as «electric shock». 52,4±7,7% of the patients described temperature changes of the skin, 28,6±7,0% of them told about allodynia. The given pain can be correctly diagnosed on rare occasions. It brings about the low efficiency of currently prescribed standard pain treatment. It was 20%-effective only for ¼ of the patients. In sum, it can be brought into focus that each 10th oncology patient of the II clinical group in Kazakhstan may potentially suffer from the chronic neuropathic pain syndrome. The given syndrome in cancer patients requires selective differential diagnostics and constant management of the pain treatment regimen because of occurrence of standard regimens incapacity, progression of tolerance to the actual pain treatment and significant deterioration of oncology patients' life quality.

    Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes after treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical outcomes in a large database of chronic pain patients. In this observational cohort study, participants were 2272 patients treated in one of 3 university-affiliated multidisciplinary pain treatment centers. All patients received personalized care, including medical, psychological, and/or physical interventions. Patient expectations regarding pain relief and improvements in quality of life and functioning were measured before the first visit to the pain centers and served as predictor variables. Changes in pain intensity, depressive symptoms, pain interference, and tendency to catastrophize, as well as satisfaction with pain treatment and global impressions of change at 6-month follow-up, were considered as treatment outcomes. Structural equation modeling analyses showed significant positive relationships between expectations and most clinical outcomes, and this association was largely mediated by patients' global impressions of change. Similar patterns of relationships between variables were also observed in various subgroups of patients based on sex, age, pain duration, and pain classification. Such results emphasize the relevance of patient expectations as a determinant of outcomes in multimodal pain treatment programs. Furthermore, the results suggest that superior clinical outcomes are observed in individuals who expect high positive outcomes as a result of treatment. PMID:26447703

    During pregnancy most of women will experience some kind of pain, either as a result of a pre-existing condition (low back pain, headache, fibromyalgia, and rheumatoid arthritis) or as a direct consequence of pregnancy (weight gain, postural changes, pelvic floor dysfunction, hormonal factors). However, chronic pain management during pregnancy and lactation remains a challenge for clinicians and pregnant women are at risk of undertreatment for painful conditions, because of fear about use of drugs during pregnancy. Few analgesic drugs have been demonstrated to be absolutely contraindicated during pregnancy and breastfeeding, but studies in pregnant women are not available for most of pain medications. The aim of this paper is to review the safety profile in pregnancy or lactation of the commonly prescribed pain medications and non-pharmacological treatments. In addition to the conventional classifications from the Food and Drug Administration and the American Academy of Paediatrics, authors analyzed the currently available clinical data from literature.

    Breakthrough cancer pain (BCP) is common in patients with cancer, causing a negative impairment in quality of life. Recent diagnostic criteria allow for differentiation of background chronic pain and BCP, for which proportion of unpredictable episodes is very high. Five characteristics define BCP: rapid onset, high intensity, maximum intensity (minutes), mean duration 30 min, and unpredictable onset. Fentanyl is a synthetic opioid characterized by rapid absorption and start of the analgesic effects. In addition to comparing some of the marked differences between the four pharmaceutical forms of fentanyl marketed in Spain, this paper discusses the data collected in a comprehensive clinical trial program with fentanyl pectin nasal spray (FPNS), a formulation that takes advantage of the intranasal route and the PecSys™ technology. The FPNS formulation achieves analgesic action 5 min after application and significant pain relief at 10 min. FPNS, therefore, has key features to be an optimal treatment for BCP. PMID:23263914

    With the technological advances in cancer diagnosis and treatment, the survival rates for patients with cancer are prolonged. The issue of figuring out how to improve the life quality of patients with cancer has become increasingly prominent. Pain, especially bone pain, is the most common symptom in malignancy patients, which seriously affects the life quality of patients with cancer. The research of cancer pain has a breakthrough due to the development of the animal models of cancer pain in recent years, such as the animal models of mouse femur, humerus, calcaneus, and rat tibia. The establishment of several kinds of animal models related to cancer pain provides a new platform in vivo to investigate the molecular mechanisms of cancer pain. In this review, we focus on the advances of cancer pain from bone metastasis, the mechanisms involved in cancer pain, and the drug treatment of cancer pain in the animal models. PMID:26316696

    The public and healthcare professionals have become increasingly aware and accepting of the benefit in physical, psychological, social, and spiritual support for patients with cancer. Patients with cancer often seek nonpharmacologic interventions to complement conventional care and decrease the pain associated with cancer and its treatment. Most often referred to as complementary and alternative medicine (CAM), these supportive therapies consist of a heterogeneous group of modalities used as adjuncts to allopathic health care. Biofield therapies are CAM modalities that involve the direction of healing energy through the hands to facilitate well-being by modifying the energy field of the body. This critical review of studies of biofield therapies emphasizes research using these modalities to decrease pain in patients with cancer. Although the therapies have demonstrated clinical efficacy, additional research is warranted. Oncology nurses should familiarize themselves with biofield therapies so they can offer informed recommendations to patients with cancer experiencing pain. PMID:22297006

    The knowledge of biological pain mechanisms are not sufficient for the understanding of patients with chronic pain syndromes such as low back, cervicobrachial and muscle pain. Psychological and psychosocial aspects play important roles in the setting and perpetuation of symptoms. Mood and anxiety disorders, secondary gains such as early retirement and financial compensations, must all be acknowledged by the physician as possible contributors to the symptoms. Abnormal illness behavior may better characterize patients with chronic pain syndromes. Behavior observation, which is akin to medical practice, is therefore a powerful tool in the diagnosis and management of these syndromes. Physicians ought be very careful in not reinforcing the patients already strong organic convictions regarding their symptoms, avoiding making decisions based on patients complaints and alleged disabilities, and assigning poorly defined and disputable diagnosis labels. Society needs also to refrain from policies that encourage abnormal illness behaviors. PMID:10849642

    Researchers have seldom invited patients with chronic pain to describe their lived experiences. This phenomenologic study involved in-depth interviews with nine women and four men with nonmalignant chronic pain. The essence of participants' experiences was unremitting torment by a force or monster that cannot be tamed. The body was altered and recalcitrant, the life world was shrunken, and the pain set up a barrier that separated them from other people. Time seemed to stop; the future was unfathomable. Findings of this study contribute to the phenomenological literature that explores the human body and its symbolic meanings and call into question the idealized positive depiction of chronic illness that is prominent in contemporary literature.

    Henceforth, ultrasonography (US) is an indispensible imaging technique in regional anesthesia practice. With the guidance of US, various invasive interventions in chronic pain pathologies of the musculoskeletal system, peripheral and neuroaxial pathologies has become possible. The management includes diagnostic blocks as weel as radiofrequency ablation and institution of neurolythic agents. During these algologic interventions we are able to see the target tissue, the dispersion of the drug and all nearby vascular structures. Besides these the US also protects the team from ionic radiation that one encounters when using flouroscopy of computed tomography. Latest publication in this field show that applicability of US in chronic pain syndromes is rapidly expanding with a good future. The additional equipment (echogenic needles, 3-D US etc.) will also expands its applications in algology practice. This review highlights different applications of US in chronic pain conditions.

    Pain catastrophizing (PC) has been related to pain levels in both patients experiencing acute or chronic pain and in healthy volunteers exposed to experimental pain. Still, it is unclear whether high levels of pain catastrophizing lead to high levels of pain or vice versa. We therefore tested whether levels of pain catastrophizing could be increased and decreased in the same participant through hypnotic suggestions and whether the altered level of situation-specific pain catastrophizing was related to increased and decreased pain levels, respectively. Using the spontaneous pain of 22 patients with chronic tension-type headache and experimentally induced pain in 22 healthy volunteers, participants were tested in 3 randomized sessions where they received 3 types of hypnotic suggestions: Negative (based on the 13 items in the Pain Catastrophizing Scale), Positive (coping-oriented reversion of the Pain Catastrophizing Scale), and Neutral (neutral sentence) hypnotic suggestions. The hypnotic suggestions significantly increased and decreased situation-specific PC in both patients and healthy volunteers (P < 0.001). Also, the levels of pain intensity and pain unpleasantness were significantly altered in both patients and healthy volunteers (P < 0.001). Furthermore, regression analyses showed that changes in pain catastrophizing predicted changes in pain in patients (R = 0.204-0.304; P < 0.045) and in healthy volunteers (R = 0.328-0.252; P < 0.018). This is the first study to successfully manipulate PC in positive and negative directions in both patients with chronic pain and healthy volunteers and to show that these manipulations significantly influence pain levels. These findings may have important theoretical and clinical implications. PMID:26871534

    We tested the hypothesis that chronic pain development (pain chronification) and ongoing chronic pain (chronic pain) reduce the activity and induce plastic changes in an endogenous analgesia circuit, the ascending nociceptive control. An important mechanism mediating this form of endogenous analgesia, referred to as capsaicin-induced analgesia, is its dependence on nucleus accumbens μ-opioid receptor mechanisms. Therefore, we also investigated whether pain chronification and chronic pain alter the requirement for nucleus accumbens μ-opioid receptor mechanisms in capsaicin-induced analgesia. We used an animal model of pain chronification in which daily subcutaneous prostaglandin E2 (PGE2) injections into the rat's hind paw for 14 days, referred to as the induction period of persistent hyperalgesia, induce a long-lasting state of nociceptor sensitization referred to as the maintenance period of persistent hyperalgesia, that lasts for at least 30 days following the cessation of the PGE2 treatment. The nociceptor hypersensitivity was measured by the shortening of the time interval for the animal to respond to a mechanical stimulation of the hind paw. We found a significant reduction in the duration of capsaicin-induced analgesia during the induction and maintenance period of persistent mechanical hyperalgesia. Intra-accumbens injection of the μ-opioid receptor selective antagonist Cys(2),Tyr(3),Orn(5),Pen(7)amide (CTOP) 10 min before the subcutaneous injection of capsaicin into the rat's fore paw blocked capsaicin-induced analgesia. Taken together, these findings indicate that pain chronification and chronic pain reduce the duration of capsaicin-induced analgesia, without affecting its dependence on nucleus accumbens μ-opioid receptor mechanisms. The attenuation of endogenous analgesia during pain chronification and chronic pain suggests that endogenous pain circuits play an important role in the development and maintenance of chronic pain.

    The perpetual pursuit of pain elimination has been constant throughout human history and pervades human cultures. In some ways it is as old as medicine itself. Cultures throughout history have practiced the art of pain management through remedies such as oral ingestion of herbs or techniques believed to have special properties. In fact, even Hippocrates wrote about the practice of trepanation, the cutting of holes in the body to release pain. Current therapies for management of pain include the pervasive utilization of opioids, which have an extensive history, spanning centuries. There is general agreement about the appropriateness of opioids for the treatment of acute and cancer pain, but the long-term use of these drugs for treatment of chronic non-malignant pain remains controversial. The pros and cons regarding these issues are beyond the scope of this review. Instead, the purpose of this review will be directed towards the pharmacology of commonly prescribed opioids in the treatment of various chronic pain syndromes. Opium, derived from the Greek word for "juice," is extracted from the latex sap of the opium poppy (Papaverum somniferum). The juice of the poppy is the source of some 20 different alkaloids of opium. These alkaloids of opioids can be divided into 2 chemical classes: phenanthrenes (morphine, codeine, and thebaine) and benzylisoquinolines (agents that do not interact with opioid receptors).

    The past two decades have contributed a large body of preclinical work that has assisted in our understanding of the underlying pathophysiological mechanisms that cause chronic pain. In this context, it has been recognized that effective treatment of pain is a priority and that treatment often involves the use of one or a combination of agents with analgesic action. The current review presents an evidence-based approach to the pharmacotherapy of chronic pain. Medline searches were done for all agents used as conventional treatment in chronic pain. Published papers up to June 2005 were included. The search strategy included randomized, controlled trials, and where available, systematic reviews and meta-analyses. Further references were found in reference sections of papers located using the above search strategy. Agents for which there were no controlled trials supporting efficacy in treatment of chronic pain were not included in the present review, except in cases where preclinical science was compelling, or where initial human work has been positive and where it was thought the reader would be interested in the scientific evidence to date.

    1993-05-01

    Pain, and especially cancer pain, is not a pure nociceptive, physical experience, but involves different dimensions of man, such as personality, affect, cognition, behavior and social relations. Cancer pain is best conceptualized as the convergence of multiple activated systems with feedback mechanisms to a complex, multidimensional model. The psychosocial aspects of this multidimensional model will be analyzed with special emphasis on results from recent research. Although most research has been conducted on the role of affect and cognition in cancer pain, data on other factors such as personality, behavior or social aspects exist and will be presented. In the second part of this paper the implications of these results for therapeutic strategies in clinical work will be discussed. Although a considerable body of knowledge exists to support the hypothesis of a multidimensional model of cancer pain, where psychosocial variables play an important role, only a few studies address the issue of to what degree different factors exercise their influence. This may be different from patient to patient and may change over the course of the disease. Whatever importance these single variables in the multidimensional model of cancer pain may have, the patient is best treated when none of these aspects is neglected in the assessment and all are taken care of in the treatment. A multidisciplinary team, with a psychiatrist as one of the team members, is often best prepared to fulfill this task. PMID:8149139

    Chronic pain in the orofacial region has always been a vexing problem for dentists to diagnose and treat effectively. For trigeminal neuropathic pain, there are 3 medications (gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors) to use plus topical anesthetics that have therapeutic efficacy. For chronic daily headaches (often migraine in origin), 3 prophylactic medications have reasonable therapeutic efficacy (β-blockers, tricyclic antidepressants, and antiepileptic drugs). The 3 Food and Drug Administration-approved drugs for fibromyalgia (pregabalin, duloxetine, and milnacipran) are not robust, with poor efficacy. For osteroarthritis, nonsteroidal anti-inflammatory drugs have therapeutic efficacy and when gastritis contraindicates them, corticosteriod injections are helpful. PMID:27475515

    The treatment of pain in the patient with cancer has focused attention on a series of controversial issues involving medical, social, and moral factors. The medical factors include a lack of knowledge on the part of health care professionals regarding the rational use of opioid drugs. This is coupled with real limitations in the general understanding of the mechanisms of pain and its treatment using pharmacologic, anesthetic, and neurosurgical approaches. Several pharmacologic controversies, including the choice of drug, route and method of administration, and tolerance development and risk of substance abuse, have emerged with the use of opioids on a chronic basis in the cancer population. The social and moral implications involve the issue of who will pay for high technology pain management approaches for patients either at home or in hospice care and the ethical considerations in managing pain with opioid drugs. Carefully designed studies to assess these factors, coupled with broad educational programs, will improve the care of cancer patients in pain and expand our understanding of these important issues.

    Risky decision-making seems to be markedly disrupted in patients with chronic pain, probably due to the high cost that impose pain and negative mood on executive control functions. Patients’ behavioral performance on decision-making tasks such as the Iowa Gambling Task (IGT) is characterized by selecting cards more frequently from disadvantageous than from advantageous decks, and by switching often between competing responses in comparison with healthy controls (HCs). In the present study, we developed a simple heuristic model to simulate individuals’ choice behavior by varying the level of decision randomness and the importance given to gains and losses. The findings revealed that the model was able to differentiate the behavioral performance of patients with chronic pain and HCs at the group, as well as at the individual level. The best fit of the model in patients with chronic pain was yielded when decisions were not based on previous choices and when gains were considered more relevant than losses. By contrast, the best account of the available data in HCs was obtained when decisions were based on previous experiences and losses loomed larger than gains. In conclusion, our model seems to provide useful information to measure each individual participant extensively, and to deal with the data on a participant-by-participant basis. PMID:25136301

    Many people worldwide suffer from pain and a portion of these sufferers are diagnosed with a chronic pain condition. The management of chronic pain continues to be a challenge, and despite taking prescribed medication for pain, patients continue to have pain of moderate severity. Current pain therapies are often inadequate, with side effects that limit medication adherence. There is a need to identify novel therapeutic targets for the management of chronic pain. One potential candidate for the treatment of chronic pain is therapies aimed at modulating the vasoactive peptide endothelin-1. In addition to vasoactive properties, endothelin-1 has been implicated in pain transmission in both humans and animal models of nociception. Endothelin-1 directly activates nociceptors and potentiates the effect of other algogens, including capsaicin, formalin, and arachidonic acid. In addition, endothelin-1 has been shown to be involved in inflammatory pain, cancer pain, neuropathic pain, diabetic neuropathy, and pain associated with sickle cell disease. Therefore, endothelin-1 may prove a novel therapeutic target for the relief of many types of chronic pain. PMID:25210474

    Persistent and disabling pain is the hallmark of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, disease severity (as measured by objective indexes such as those that use radiography or serology) is only marginally related to patients' reports of pain severity, and pain-related presentation can differ widely among individuals with CP/CPPS. Increasing evidence in support of the biopsychosocial model of pain suggests that cognitive and emotional processes are crucial contributors to inter-individual differences in the perception and impact of pain. This review describes the growing body of literature relating depression and catastrophizing to the experience of pain and pain-related sequelae in CP/CPPS. Depression and catastrophizing are consistently associated with the reported severity of pain, sensitivity to pain, physical disability, poor treatment outcomes, and inflammatory disease activity and potentially with early mortality. A variety of pathways, from cognitive to behavioral to neurophysiological, seem to mediate these deleterious effects. Collectively, depression and catastrophizing are critically important variables in understanding the experience of pain in patients with CP/CPPS. Pain, depression, and catastrophizing might all be uniquely important therapeutic targets in the multimodal management of a range of such conditions. PMID:23869268

    Chronic visceral pain syndromes are important clinical problems with largely unmet medical needs. Based on the common overlap with other chronic disorders of visceral or somatic pain, mood and affect, and their responsiveness to centrally targeted treatments, an important role of central nervous system in their pathophysiology is likely. A growing number of brain imaging studies in irritable bowel syndrome, functional dyspepsia and bladder pain syndrome/interstitial cystitis has identified abnormalities in evoked brain responses, resting state activity and connectivity, as well as in grey and white matter properties. Structural and functional alterations in brain regions of the salience, emotional arousal, and sensorimotor networks, as well as in prefrontal regions, are the most consistently reported findings. Some of these changes show moderate correlations with behavioral and clinical measures. Most recently, data driven machine-learning approaches to larger data sets have been able to classify visceral pain syndromes from healthy control subjects. Future studies need to identify the mechanisms underlying the altered brain signatures of chronic visceral pain and identify targets for therapeutic interventions. PMID:25789437

    Chronic nonspecific neck pain is a common problem in rheumatology and may resist conventional treatment. Pathophysiological links exist between the cervical spine and masticatory system. Occlusal disorders may cause neck pain and may respond to dental treatment. The estimated prevalence of occlusal disorders is about 45%, with half the cases being due to functional factors. Minor repeated masticatory dysfunction (MD) with craniocervical asymmetry is the most common clinical picture. The pain is usually located in the suboccipital region and refractory to conventional treatment. The time pattern may be suggestive, with nocturnal arousals or triggering by temporomandibular movements. MD should be strongly suspected in patients with at least two of the following: history of treated or untreated MD, unilateral temporomandibular joint pain and clicking, lateral deviation during mouth opening, and limitation of mouth opening (less than three fingerbreadths). Rheumatologists should consider MD among causes of neck pain, most notably in patients with abnormal craniocervical posture, signs linking the neck pain to mastication, and clinical manifestations of MD. Evidence suggesting that MD may cause neck pain has been published. However, studies are needed to determine whether treatment of MD can relieve neck pain. PMID:16226475

    An overview is given on the current classification, description and treatment of chronic pain with causally relevant psychological factors. It is based on the "practice guidelines on somatoform disorders" and on a thematically related meta-analysis. The classificatory problems, especially of the demarcation of somatoform and other chronic pain, are presented. Additional descriptive dimensions of the relevant psychosocial factors are: pain description, other organically unexplained pain- and non-pain-symptoms, anxiety and depression, disease conviction and illness behaviour, personality and childhood abuse. A modified psychotherapy for (somatoform) chronic pain is outlined. Finally, this aetiologically oriented psychosomatic-psychiatric approach is compared to psychological coping models for chronic pain. PMID:15138684

    We intend to present some aspects related with the coping process in a person with chronic pain. The presence of pain has implications in daily life activities, such as eating, drinking, sleeping or selfcare. Pain can unchain responses in the person, namely depression, anxiety, isolation, fear of pain and pessimistic thoughts. Thus we verify that in his/her adaptation process to the condition of chronic pain the person needs to integrate some strategies to manage his/her day by day activities. In this article we try to systematize the process where nurses based on Lazarus and Folkman's Model: Stress processing and Coping, can systematize care. In fact, nurses try to help people in the identification of their personal resources as well as the socio-ecological resources. The sense the care process has as a goal is the improvement of the quality of life through pain control and the person's adaptation of his/her condition of health, through development of his/her knowledge and capacities to use the resources, be they personal as instrumental or social.

    Introduction: This is a case presentation of a 45-year-old male with chronic donor site pain following autologous iliac crest bone harvest successfully treated with superior cluneal nerve blockade. Donor site pain following autologous bone harvest is a common postoperative complication of lumbar fusion procedures that can cause significant morbidity and diminish quality of life, even in the context of an otherwise successful surgery. Dysfunction of the superior cluneal nerves is an etiology of this chronic pain. The patient’s medical history, attempted treatments, and literature were reviewed. Case Presentation: A 45-year-old male with a six year history of severe pain over the right iliac crest following an otherwise successful lumbar laminectomy and fusion underwent two sets of superior cluneal nerve blocks, with sustained relief of more than 80% at seven months follow up. Conclusions: Donor site pain following autologous iliac crest bone harvest is a common surgical complication that is often resistant to conservative treatments such as physical therapy and oral medications. Blockade of the superior cluneal nerves is a safe and technically simple procedure that may result in long-term pain relief, obviating the need to consider more invasive options. PMID:26587399

    Pain is unfortunately a quite common symptom for cancer patients. Normally pain starts as an episodic experience at early cancer phases to become chronic in later stages. In order to improve the quality of life of oncological patients, anti-cancer treatments are often accompanied by analgesic therapies. The P2X receptor are adenosine triphosphate (ATP) gated ion channels expressed by several cells including neurons, cancer and immune cells. Purinergic signaling through P2X receptors recently emerged as possible common pathway for cancer onset/growth and pain sensitivity. Indeed, tumor microenvironment is rich in extracellular ATP, which has a role in both tumor development and pain sensation. The study of the different mechanisms by which P2X receptors favor cancer progression and relative pain, represents an interesting challenge to design integrated therapeutic strategies for oncological patients. This review summarizes recent findings linking P2X receptors and ATP to cancer growth, progression and related pain. Special attention has been paid to the role of P2X2, P2X3, P2X4 and P2X7 in the genesis of cancer pain and to the function of P2X7 in tumor growth and metastasis. Therapeutic implications of the administration of different P2X receptor blockers to alleviate cancer-associated pain sensations contemporarily reducing tumor progression are also discussed.

    Chronic pain is common and complex and has a large impact on individuals and society. Good epidemiological pain data provide key information on the use of resources (both in general practice and in specialist clinics), insight into factors that lead to or favour chronicity and the design of interventions aimed at reducing or preventing the effects of chronic pain. This review aims to highlight the important factors associated with chronic pain, including those factors which are amenable to lifestyle intervention. PMID:26516524

    The cause of chronic pelvic pain syndrome (CPPS) has yet to be established. Since the late 1980s, cytokine, chemokine, and immunological classification studies using human samples have focused on identifying biomarkers for CPPS, but no diagnostically beneficial biomarkers have been identified, and these studies have done little to deepen our understanding of the mechanisms underlying chronic prostatic pain. Given the large number of men thought to be affected by this condition and the ineffective nature of current treatments, there is a pressing need to elucidate these mechanisms. Prostatitis types IIIa and IIIb are classified according to the presence of pain without concurrent presence of bacteria; however, it is becoming more evident that, although levels of bacteria are not directly associated with levels of pain, the presence of bacteria might act as the initiating factor that drives primary activation of mast-cell-mediated inflammation in the prostate. Mast cell activation is also known to suppress regulatory T cell (Treg) control of self-tolerance and also activate neural sensitization. This combination of established autoimmunity coupled with peripheral and central neural sensitization can result in the development of multiple symptoms, including pelvic pain and bladder irritation. Identifying these mechanisms as central mediators in CPPS offers new insight into the prospective treatment of the disease. PMID:24686526

    Background/Study Context Chronic pain is associated with increased interference in daily functioning that becomes more pronounced as pain intensity increases. Based on previous research showing that older adults maintain well-being in the face of pain as well as or better than their younger counterparts, the current study examined the interaction of age and pain intensity on interference in a sample of chronic orofacial pain patients. Methods Data were obtained from the records of 508 chronic orofacial pain patients being seen for an initial evaluation from 2008 to 2012. Collected data included age (range: 18–78) and self-reported measures of pain intensity and pain interference. Bivariate correlations and regression models were used to assess for statistical interactions. Results Regression analyses revealed that pain intensity positively predicted pain interference (R2 = .35, B = 10.40, SE = 0.62, t(507) = 16.70, p < .001). A significant interaction supported the primary hypothesis that aging was associated with reduced interference at high levels of pain intensity (ΔR2 = .01, B = −1.31, SE = 0.63, t(505) = −2.90, p = .04). Conclusion At high levels of pain intensity, interference decreased with age, although the age by pain intensity interaction effect was small. This evidence converges with aging theories, including socioemotional selectivity theory, which posits that as people age, they become more motivated to maximize positive emotions and minimize negative ones. The results highlight the importance of studying the mechanisms older adults use to successfully cope with pain. PMID:26214102

    Chronic pain affects nearly one-third of the American population. Chronic pain can lead to a variety of problems for a pain sufferer, including developing secondary medical problems, depression, functional and vocational disability, opioid abuse and suicide. Current pain care models are deficient in providing a necessary comprehensive approach. Most patients with chronic pain are managed by primary care clinicians who are typically ill prepared to effectively and efficiently manage these cases. A biopsychosocial approach to evaluate and treat chronic pain is clinically and economically efficacious, but unique delivery systems are required to meet the challenge of access to specialty care.

    Chronic pain is associated with symptoms that may impair a patient's quality of life, including emotional distress, fatigue, and sleep disturbance. There is a high prevalence of concomitant pain and sleep disturbance. Studies support the hypothesis that sleep and pain have a bidirectional and reciprocal relationship. Clinicians who manage patients with chronic pain often focus on interventions that relieve pain, and assessing and treating sleep disturbance are secondary or not addressed. This article reviews the literature on pain and co-occurring sleep disturbance, describes the assessment of sleep disturbance, and outlines nonpharmacologic and pharmacologic treatment strategies to improve sleep in patients with chronic pain.

  7. Chronic pain, perceived stress, and cellular aging: an exploratory study

    PubMed Central

    2012-01-01

    Background Chronic pain conditions are characterized by significant individual variability complicating the identification of pathophysiological markers. Leukocyte telomere length (TL), a measure of cellular aging, is associated with age-related disease onset, psychosocial stress, and health-related functional decline. Psychosocial stress has been associated with the onset of chronic pain and chronic pain is experienced as a physical and psychosocial stressor. However, the utility of TL as a biological marker reflecting the burden of chronic pain and psychosocial stress has not yet been explored. Findings The relationship between chronic pain, stress, and TL was analyzed in 36 ethnically diverse, older adults, half of whom reported no chronic pain and the other half had chronic knee osteoarthritis (OA) pain. Subjects completed a physical exam, radiographs, health history, and psychosocial questionnaires. Blood samples were collected and TL was measured by quantitative polymerase chain reaction (qPCR). Four groups were identified characterized by pain status and the Perceived Stress Scale scores: 1) no pain/low stress, 2) no pain/high stress, chronic pain/low stress, and 4) chronic pain/high stress. TL differed between the pain/stress groups (p = 0.01), controlling for relevant covariates. Specifically, the chronic pain/high stress group had significantly shorter TL compared to the no pain/low stress group. Age was negatively correlated with TL, particularly in the chronic pain/high stress group (p = 0.03). Conclusions Although preliminary in nature and based on a modest sample size, these findings indicate that cellular aging may be more pronounced in older adults experiencing high levels of perceived stress and chronic pain.

    Persistent pain is a serious problem that often contributes to a poor quality of life in pancreatic cancer patients. Medical management by opioid analgesics is often accompanied by side effects and incomplete pain relief. A celiac plexus block is a simple treatment which relieves pain, but the procedure demands a certain degree of proficiency and the duration of the effects obtained can be rather limited. Transhiatal bilateral splanchnicectomy achieves a certain denervation of splanchnic nerves, but it requires a laparotomy. Unilateral thoracoscopic splanchnicectomy is a minimally invasive procedure to cause definite denervation. Bilateral thoracoscopic splanchnicectomy is recommended for unsatisfactory cases or recurrent pain occurring after the initial unilateral splanchnicectomy. It is important to select the most suitable treatment depending on patients' actual medical state and the predicted outcomes. PMID:24868557

    Pain is a major symptom in cancer patients, and most cancer patients with advanced or terminal cancers suffer from chronic pain related to treatment failure and/or tumor progression. In the present study, we examined the development of cancer pain in mice. Murine hepatocarcinoma cells, HCa-1, were inoculated unilaterally into the thigh or the dorsum of the foot of male C3H/HeJ mice. Four weeks after inoculation, behavioral signs were observed for mechanical allodynia, cold allodynia, and hyperalgesia using a von Frey filament, acetone, and radiant heat, respectively. Bone invasion by the tumor commenced from 7 days after inoculation of tumor cells and was evident from 14 days after inoculation. Cold allodynia but neither mechanical allodynia nor hyperalgesia was observed in mice that received an inoculation into the thigh. On the contrary, mechanical allodynia and cold allodynia, but not hyperalgesia, were developed in mice with an inoculation into the foot. Sometimes, mirror-image pain was developed in these animals. These results suggest that carcinoma cells injected into the foot of mice may develop severe chronic pain related to cancer. This animal model of pain would be useful to elucidate the mechanisms of cancer pain in humans. PMID:15861499

    The case was presented here in order to point out that an immunocompetent child might have Strongyloidiosis infection that might be misdiagnosed. A 9 year old male patient who had chronic abdominal pain with a feeling of weakness was treated several times for urinary tract infection. He had never been tested for the presence of parasites. After the patient's complaints occurred again, he presented at our hospital. Strongyloides stercoralis larvae were observed in his feces by microscopy. Albendazol (400 mg/day for three days) was prescribed. After 10 days, the feces of the patient was reexamined and no Strongyloides stercoralis larvae were detected. For this reason, it is important to investigate the possibility of intestinal parasitic infections in children with chronic abdominal pain. PMID:18645954

    Conventional treatments have not slowed down the ever expanding low back pain (LBP) problem. Traditional treatment has most probably contributed to the growth of the problem. Therefore, in a search for new solutions, 'functional restoration' has been devised. In connection with chronic LBP the term has been associated with a full-day program lasting from 3 to 5 weeks. It includes multidisciplinary treatment of patients in groups with intensive physical and ergonomic training, psychological pain management, back school, as well as teaching in social/work related issues. The key concepts are 'acceptance of the pain', 'activity', 'self-responsibility', 'multidisciplinary' and 'quantitative functional evaluation (QFE)'. The latter is aimed so that the participants can feel the physical improvement, encouraging them to be able to go back to work, or at least to lead a more active life style. Several controlled studies suggest a lasting effect in terms of regaining their ability to work and improving pain behavior for a good part of disabled chronic LBP patients. However, it is noteworthy that randomized studies seemingly show poorer results than studies not employing randomized controls. PMID:8809926

    Pain commonly affects multiple sclerosis (MS) patients, and has the potential to become chronic and burden an already damaged central nervous system. Imaging studies are providing insights into brain restructuring associated with chronic pain and different chronic pain conditions seem to evoke distinct plasticity patterns. Our objective was to study the structural and functional brain changes of chronic neuropathic pain of MS. Employing structural and resting functional magnetic resonance imaging we compared MS patients with chronic central pain with MS patients without pain matched with respect to age, gender, subtype and duration of MS and disability. Mean duration of pain was 7.6 years. Comparing the pain and no-pain groups, brain functional default-mode network differences were found. There was decreased coactivation in the caudate nucleus and nucleus accumbens bilaterally. Also, for the relapsing-remitting subgroup of patients, grey matter thickness changes predominated in the pain group in the mesial region of the temporal lobes, caudate, putamen, thalami and the fronto-parietal cortex; in the group without pain, changes predominated in the frontopolar and orbitofrontal cortices and in the occipital areas. A dysfunction in the reward system in chronic pain of MS was found, particularly in the brain areas involved in its motivational aspects, as such probably reflecting the maladaptive physiology of chronic pain, and possibly the signature of pain in MS, in a disease where reward impairment seems to be already one of its features.

    Aims To explore the relationship between chronic pain and characteristics, behaviors, and psychological status of suburban Connecticut injection drug users. Methods Cross-sectional study with quantitative interview and serological testing for HIV and hepatitis B and C in 456 individuals who injected drugs in the past month were dichotomized into those reporting current chronic pain of at least six months duration and all others. The interview covered (i) sociodemographics, (ii) injection drug use, (iii) interactions with drug treatment, criminal justice, and harm reduction, (iv) screening for alcohol use, chronic pain, anxiety, and depression, and (v) knowledge regarding HIV, hepatitis B (HBV) and C (HCV), and opioid overdose. Serological testing for HIV, HBV, and HCV was conducted. Results One-third (n=143) reported chronic pain. These individuals differed significantly from those not reporting chronic pain on characteristics that included older age, lower educational achievement, and injection of pharmaceutical opioids. They also reported experiencing more psychological and family problems on the ASI and higher levels of depression and anxiety. Four of five individuals with chronic pain (117 of 148 providing chronology data) reported non-medical opioid use prior to the onset of chronic pain. Conclusions Chronic pain is common among drug injectors in our study population although it was unusual for chronic pain to have preceded non-medical opioid use. Psychological problems in injectors with co-occurring chronic pain are likely pose significant complications to successful treatment for substance abuse, pain, or infectious disease treatment.

    Chronic pain is pathological, persisting beyond normal tissue healing time. Previous work has suggested ∼50% variation in chronic pain development is heritable. No data are currently available on the heritability of pain categorized using the Chronic Pain Grade (CPG). Furthermore, few existing studies have accounted for potential confounders that may themselves be under genetic control or indeed 'heritable' non-genetic traits. This study aimed to determine the relative contributions of genetic, measured and shared environmental and lifestyle factors to chronic pain. Chronic pain status was determined and CPG measured in participants from Generation Scotland: the Scottish Family Health Study, a large cohort of well-characterized, extended families from throughout Scotland, UK. Heritability estimates (h (2) ) for 'any chronic pain' and 'severe' chronic pain (CPG 3 or 4) were generated using SOLAR software, with and without adjustment for shared household effects and measured covariates age, body mass index, gender, household income, occupation and physical activity. Data were available for 7644 individuals in 2195 extended families. Without adjustment, h (2) for 'any chronic pain' was 29% [standard errors (SE) 6%; p < 0.001], and for 'severe' chronic pain was 44% (SE 3%; p <0.001). After adjustment, 'any chronic pain' h(2) = 16% (SE 7%; p = 0.02) and 'severe' chronic pain h(2) = 30% (SE 13%; p = 0.007). Co-heritability of both traits was 11% (SE 76%). This study supports the use of chronic pain as a phenotype in genetic studies, with adequate correction for confounders to specifically identify genetic risk factors for chronic pain. PMID:22337623

    Purpose Research into the pathophysiology of chronic prostatitis/chronic pelvic pain syndrome has primarily focused on markers of peripheral dysfunction. We present the first neuroimaging investigation to our knowledge to characterize brain function and anatomy in chronic prostatitis/chronic pelvic pain syndrome. Materials and Methods We collected data from 19 male patients with chronic prostatitis/chronic pelvic pain syndrome, and 16 healthy age and gender matched controls. Functional magnetic resonance imaging data were obtained from 14 patients with chronic prostatitis/chronic pelvic pain syndrome as they rated spontaneous pain inside the scanner. Group differences (16 patients per group) in gray matter total volume and regional density were evaluated using voxel-based morphometry, and white matter integrity was studied with diffusion tensor imaging to measure fractional anisotropy. Functional and anatomical imaging outcomes were correlated with the clinical characteristics of chronic prostatitis/chronic pelvic pain syndrome. Results Spontaneous pelvic pain was uniquely characterized by functional activation within the right anterior insula, which correlated with clinical pain intensity. No group differences were found in regional gray matter volume, yet density of gray matter in pain relevant regions (anterior insula and anterior cingulate cortices) positively correlated with pain intensity and extent of pain chronicity. Moreover the correlation between white matter anisotropy and neo-cortical gray matter volume was disrupted in chronic prostatitis/chronic pelvic pain syndrome. Conclusions We provide novel evidence that the pain of chronic prostatitis/chronic pelvic pain syndrome is associated with a chronic pelvic pain syndrome specific pattern of functional brain activation and brain anatomical reorganization. These findings necessitate further investigations into the role of central mechanisms in the initiation and maintenance of chronic prostatitis/chronic

  16. Neuroimmune interactions in itch: Do chronic itch, chronic pain, and chronic cough share similar mechanisms?

    PubMed

    2015-12-01

    Itch and pain are closely related but also clearly distinct sensations. Pain is known to suppress itch, while analgesics such as morphine can provoke itch. However, in pathological and chronic conditions, pain and itch also have similarities. Dysfunction of the nervous system, as manifested by neural plastic changes in primary sensory neurons of the peripheral nervous system (peripheral sensitization) and spinal cord and brain stem neurons in the central nervous system (central sensitization) will result in chronic pain and itch. Importantly, these diseases also result from immune dysfunction, since inflammatory mediators can directly activate or sensitize nociceptive and pruriceptive neurons in the peripheral and central nervous system, leading to pain and itch hypersensitivity. In this mini-review, I discuss the roles of Toll-like receptors (TLRs), transient receptor potential ankyrin 1 (TRPA1) ion channel, and Nav1.7 sodium channel in regulating itch and inflammation, with special emphasis of neuronal TLR signaling and the interaction of TLR7 and TRPA1. Chronic pain and chronic itch are debilitating diseases and dramatically impact the life quality of patients. Targeting TLRs for the control of inflammation, neuroinflammation (inflammation restricted in the nervous system), and hyperexcitability of nociceptors and pruriceptors will lead to new therapeutics for the relief of chronic pain and chronic itch. Finally, given the shared mechanisms among chronic cough, chronic pain, and chronic itch and the demonstrated efficacy of the neuropathic pain drug gabapentin in treating chronic cough, novel therapeutics targeting TRPA1, Nav1.7, and TLRs may also help to alleviate refractory cough via modulating neuron-immune interaction.

    Chronic pain is one of the most prevalent health problems in our modern world, with millions of people debilitated by conditions such as back pain, headache and arthritis. To address this growing problem, many people are turning to mind–body therapies, including meditation, yoga and cognitive behavioural therapy. This article will review the neural mechanisms underlying the modulation of pain by cognitive and emotional states — important components of mind–body therapies. It will also examine the accumulating evidence that chronic pain itself alters brain circuitry, including that involved in endogenous pain control, suggesting that controlling pain becomes increasingly difficult as pain becomes chronic.

    PubMed

    2016-03-01

    Chronic pain is a major medical problem that is resistant to conventional medical intervention. It also causes emotional changes such as anxiety and fear. Furthermore, anxiety or fear often enhances the suffering of pain. Based on recent studies, I propose chronic anxiety triggered by injury or chronic pain is mediated through presynaptic long-term potentiation (LTP) in the anterior cingulate cortex (ACC), a key cortical region for pain perception. Conversely, NMDA receptor-dependent postsynaptic LTP plays a more important role in behavioral sensitization in chronic pain. Thus, postsynaptic and presynaptic LTP in ACC neurons are likely the key cellular mechanisms for causing chronic pain and its associated anxiety, respectively. This suggests potential targets for treating chronic pain and related anxiety. PMID:26878750

    Chronic pancreatitis (CP) is a chronic inflammatory disease of the pancreas. The main symptom of patients with CP is chronic and severe abdominal pain. However, the pathophysiology of pain in CP remains obscure. Traditionally, researchers believed that the pain was caused by anatomical changes in pancreatic structure. However, treatment outcomes based on such beliefs are considered unsatisfactory. The emerging explanations of pain in CP are trending toward neurobiological theories. This article aims to review current evidence regarding the neuropathophysiology of pain in CP and its potential implications for the development of new treatments for pain in CP. PMID:26600977

    Background Carbamazepine is used to treat chronic neuropathic pain. Objectives Evaluation of analgesic efficacy and adverse effects of carbamazepine for acute and chronic pain management (except headaches). Search methods Randomised controlled trials (RCTs) of carbamazepine in acute, chronic or cancer pain were identified, searching MEDLINE, EMBASE, SIGLE and Cochrane CENTRAL to June 2010, reference lists of retrieved papers, and reviews. Selection criteria RCTs reporting the analgesic effects of carbamazepine. Data collection and analysis Two authors independently extracted results and scored for quality. Numbers needed to treat to benefit (NNT) or harm (NNH) with 95% confidence intervals (CI) were calculated from dichotomous data for effectiveness, adverse effects and adverse event withdrawal. Issues of study quality, size, duration, and outcomes were examined. Main results Fifteen included studies (12 cross-over design; three parallel-group) with 629 participants. Carbamazepine was less effective than prednisolone in preventing postherpetic neuralgia following acute herpes zoster (1 study, 40 participants). No studies examined acute postoperative pain. Fourteen studies investigated chronic neuropathic pain: two lasted eight weeks, others were four weeks or less (mean 3 weeks, median 2 weeks). Five had low reporting quality. Ten involved fewer than 50 participants; mean and median maximum treatment group sizes were 34 and 29. Outcome reporting was inconsistent. Most placebo controlled studies indicated that carbamazepine was better than placebo. Five studies with 298 participants provided dichotomous results; 70% improved with carbamazepine and 12% with placebo. Carbamazepine at any dose, using any definition of improvement was significantly better than placebo (70% versus 12% improved; 5 studies, 298 participants); relative benefit 6.1 (3.9 to 9.7), NNT 1.7 (1.5 to 2.0).

    The goal of this review is to discuss the psychiatric aspects of pain in cancer patients from a biopsychosocial approach. Pain in cancer patients is considered as a complex reaction causing severe suffering and involves many psychological aspects. It has many dimensions such as personality, affect, cognition and social relations. The pain experience may also be influenced by some psychological factors such as anxiety, depression and the meaning of pain. Therefore, a successful management of cancer pain requires a multidisciplinary approach. Since cancer pain is generally treated medically, the psychological impact of pain is often underestimated. However, cancer pain is usually related to high levels of psychological distress. Culture, as an important factor affecting cancer pain, will also be discussed during this review. It is crucial to understand cultural diversity in the treatment of cancer patients with pain. Research shows that a minority patients of various ethnicities have less control of their pain because of the miscommunication problem within the medical setting. By paying attention to patients' cultural diversities, problems such as miscommunication causing inadequate control of pain can be eliminated. In order to manage pain in cancer patients, cognitive-behavioral interventions may be integrated with pharmacotherapy. The main goal of these strategies is to provide a sense of control and better coping skills to deal with cancer. Patients' maladaptive thoughts or behaviors may cause physical and emotional stress. Main behavioral strategies include biofeedback, relaxation training, and hypnosis. Cognitive strategies include guided imagery, distraction, thought monitoring and problem solving. By discussing all of these aspects of cancer pain, the multidimensional characteristic of pain and the relation between cancer pain and psychiatric factors will be clarified. PMID:20590361

    The aim of the study was to determine whether children with chronic benign pain are in contact with their general practitioner (GP) more frequently than those without chronic benign pain. A random sample of children and adolescents aged between 0 and 18 years of age was drawn from the records of ten general practices. According to their responses to a pain questionnaire, subjects were assigned to the chronic benign pain group (n = 95) if they had pain of more than three months' duration, or to the control group (n = 105) if they had pain of less than three months' duration or no pain at all. All the subjects had an average GP consultation rate of 2.6 contacts per year. No significant age and sex differences were found. Chronic benign pain in childhood and adolescence is not related to increased use of healthcare services, suggesting that somatisation does not play a major role in children with chronic benign pain.

    Background Chronic pain is a major public health problem. The impact of stages of chronic pain adjusted for disease load on societal burden has not been assessed in population surveys. Methods A cross-sectional survey with 4360 people aged ≥ 14 years representative of the German population was conducted. Measures obtained included demographic variables, presence of chronic pain (based on the definition of the International Association for the Study of Pain), chronic pain stages (by chronic pain grade questionnaire), disease load (by self-reported comorbidity questionnaire) and societal burden (by self-reported number of doctor visits, nights spent in hospital and days of sick leave/disability in the previous 12 months, and by current unemployment). Associations between chronic pain stages with societal burden, adjusted for demographic variables and disease load, were tested by Poisson and logistic regression analyses. Results 2508 responses were received. 19.4% (95% CI 16.8% to 22.0%) of participants met the criteria of chronic non-disabling non-malignant pain. 7.4% (95% CI 5.0% to 9.9%) met criteria for chronic disabling non-malignant pain. Compared with no chronic pain, the rate ratio (RR) of days with sick leave/disability was 1.6 for non-disabling pain and 6.4 for disabling pain. After adjusting for age and disease load, the RRs increased to 1.8 and 6.8. The RR of doctor visits was 2.5 for non-disabling pain and 4.5 for disabling pain if compared with no chronic pain. After adjusting for age and disease load, the RR fell to 1.7 and 2.6. The RR of days in hospital was 2.7 for non-disabling pain and 11.7 for disabling pain if compared with no chronic pain. After adjusting for age and disease load, the RR fell to 1.5 and 4.0. Unemployment was predicted by lower educational level (Odds Ratio OR 3.27 [95% CI 1.70-6.29]), disabling pain (OR 3.30 [95% CI 1.76-6.21]) and disease load (OR 1.70 [95% CI 1.41-2.05]).

    Chronic musculoskeletal pain is one of the most intractable clinical problems faced by clinicians and can be devastating for patients. Central pain amplification is perceived pain that cannot be fully explained on the basis of somatic or neuropathic processes and is due to physiologic alterations in pain transmission or descending pain modulatory pathways. In any individual, central pain amplification may complicate nociceptive or neuropathic pain. Furthermore, patients with somatic symptom disorders may have alterations in their psychological or behavioral responses to pain that contribute significantly to the clinical presentation. Genetic, physiologic, and psychological factors associated with central pain amplification are beginning to be understood. One important contributor to chronic pain is perceived stress and stress response systems. We and others have shown a complex relationship between the physiologic stress response and chronic pain symptoms. Unfortunately, treatments for chronic pain are woefully inadequate and often worsen clinical outcomes. Developing new treatment strategies for patients with chronic pain is of utmost urgency. This essay provides a framework for thinking about chronic pain and developing new treatment approaches. PMID:26330672

    Pain behaviors are shaped by social demands and learning processes, and chronic pain has been previously suggested to affect their meaning. In this study, we combined functional magnetic resonance imaging with in-scanner video recording during thermal pain stimulations and use multilevel mediation analyses to study the brain mediators of pain facial expressions and the perception of pain intensity (self-reports) in healthy individuals and patients with chronic back pain (CBP). Behavioral data showed that the relation between pain expression and pain report was disrupted in CBP. In both patients with CBP and healthy controls, brain activity varying on a trial-by-trial basis with pain facial expressions was mainly located in the primary motor cortex and completely dissociated from the pattern of brain activity varying with pain intensity ratings. Stronger activity was observed in CBP specifically during pain facial expressions in several nonmotor brain regions such as the medial prefrontal cortex, the precuneus, and the medial temporal lobe. In sharp contrast, no moderating effect of chronic pain was observed on brain activity associated with pain intensity ratings. Our results demonstrate that pain facial expressions and pain intensity ratings reflect different aspects of pain processing and support psychosocial models of pain suggesting that distinctive mechanisms are involved in the regulation of pain behaviors in chronic pain.

    Effects of light upon human tissue are divided into irreversible effects and reversible effects. Irreversible effects can be called as high level laser therapy (HLLT), and reversible effects can be called as low level light therapy (LLLT). Light irradiators for chronic pain act under principle of LLLT. Laser diode, halogen lamp and xenon lamp are used as light sources for light irradiator for various chronic pain. These days, light emitting diode (LED) is used as light source for light irradiator for various kinds of pain. Light irradiators are now divided into portable light weight low power machine and heavy weight, high power machine. In the dental area Nd : YAG laser is using as HLLT tool. But, now there are many reports about Nd : YAG laser used as anesthetic machine. In these reports, topical anesthetic effects of Nd : YAG laser are immediate and with fewer side effects compared with topical anesthetic agents. These effects are explained as LLLT. Halogen lamp and xenon lamp type irradiators were also introduced. MEDILASER SOFT PULSE10, an laser diode type irradiator was withdrawn from the market. PMID:25098134

    2011-01-01

    Background Chronic pain patients are common in general practice. In this study "chronic pain" is defined as diffuse musculoskeletal pain not due to inflammatory diseases or cancer. Effective patient-physician relations improve treatment results. The relationship between doctors and chronic pain patients is often dysfunctional. Consultation training for physicians and medical students can improve the professional ability to build effective relations, but this demands a thorough understanding of the problems in the relation. Several studies have defined the issues that frequently cause problems, but few have described the process. The aim of this study was to understand and illustrate what GPs' experience in contact with chronic pain patients and what works and does not work in these consultations. Methods Our theoretical perspective is constructivist, based upon the relativist view that individuals construct realities to understand and navigate the world. Five Swedish General Practitioners (GPs), two male and three female, were interviewed and asked to tell a story about a difficult encounter with a chronic pain patient. Tapes of the interviews were transcribed and analysed using narrative analysis. Three GPs told narratives suited for our analytic tools and these were included in the final results. Results Each narrative highlights a certain dilemma and a strategy. The dilemmas were: power game; good intentions that fail when a patient is persuaded against her own conviction; persuasion of the unwilling; transferred tiredness; distrust and dissociation from the patient. Professional strategies of listening, encouraging and teamwork were central to handling difficult situations. Conclusions The narratives show that GP's consultations with chronic pain patients sometimes are characterized by conflicts and difficult situations. They are facilitated by methods such as active listening and teamwork, but still may remain hard to handle. This has not before been studied

    OBJECTIVE To estimate worldwide prevalence of chronic low back pain according to age and sex. METHODS We consulted Medline (PubMed), LILACS and EMBASE electronic databases. The search strategy used the following descriptors and combinations: back pain, prevalence, musculoskeletal diseases, chronic musculoskeletal pain, rheumatic, low back pain, musculoskeletal disorders and chronic low back pain. We selected cross-sectional population-based or cohort studies that assessed chronic low back pain as an outcome. We also assessed the quality of the selected studies as well as the chronic low back pain prevalence according to age and sex. RESULTS The review included 28 studies. Based on our qualitative evaluation, around one third of the studies had low scores, mainly due to high non-response rates. Chronic low back pain prevalence was 4.2% in individuals aged between 24 and 39 years old and 19.6% in those aged between 20 and 59. Of nine studies with individuals aged 18 and above, six reported chronic low back pain between 3.9% and 10.2% and three, prevalence between 13.1% and 20.3%. In the Brazilian older population, chronic low back pain prevalence was 25.4%. CONCLUSIONS Chronic low back pain prevalence increases linearly from the third decade of life on, until the 60 years of age, being more prevalent in women. Methodological approaches aiming to reduce high heterogeneity in case definitions of chronic low back pain are essential to consistency and comparative analysis between studies. A standard chronic low back pain definition should include the precise description of the anatomical area, pain duration and limitation level. PMID:26487293

    Chronic pain in children and adolescents can be difficult for a single provider to manage in a busy clinical setting. Part of this difficulty is that pediatric chronic pain not only impacts the child but also the families of these children. In this review article, we discuss etiology and pathophysiology of chronic pain, along with variables that impact the severity of chronic pain and functional loss. We review diagnosis and management of selected chronic pain conditions in pediatric patients, including headache, low back pain, hypermobility, chronic fatigue, postural orthostatic tachycardia syndrome, abdominal pain, fibromyalgia, and complex regional pain syndrome. For each condition, we create a road map that contains therapy prescriptions, exercise recommendations, and variables that may influence pain severity. Potential medications for these pain conditions and associated symptoms are reviewed. A multidisciplinary approach for managing children with these conditions, including pediatric pain rehabilitation programs, is emphasized. Lastly, we discuss psychological factors and interventions for pediatric chronic pain and potential complementary and alternative natural products and interventions. PMID:26568508

    Increased opioid prescribing for back pain and other chronic musculoskeletal pain conditions has been accompanied by dramatic increases in prescription opioid addiction and fatal overdose. Opioid-related risks appear to increase with dose. While short-term randomized trials of opioids for chronic pain have found modest analgesic benefits (a one-third reduction in pain intensity on average), the long-term safety and effectiveness of opioids for chronic musculoskeletal pain is unknown. Given the lack of large, long-term randomized trials, recent epidemiologic data suggests the need for caution when considering long-term use of opioids to manage chronic musculoskeletal pain, particularly at higher dosage levels. Principles for achieving more selective and cautious use of opioids for chronic musculoskeletal pain are proposed. PMID:24315147

    Chronic, nonmalignant pain is a substantial public health problem in the United States. Research over the past 2 decades has defined chronic pain by using a "biopsychosocial model" that considers a patient's biology and psychological makeup in the context of his or her social and cultural milieu. Whereas this model addresses the pathology of chronic pain, it also places many demands on the physician, who is expected to assess and manage chronic pain safely and successfully. There is a growing body of evidence suggesting that opioids can be effective in the management of chronic pain, but there has also been a rise in opioid-related overdoses and deaths. Clinicians should be aware of assessment tools that may be used to evaluate the risk of opioid abuse. A basic understanding of chronic pain pathophysiology and a uniform approach to patient care can satisfy the needs of both patients and physicians. PMID:23918913

    A longitudinal evaluation of the recovery from an acute back pain episode was undertaken on 117 sufferers, with assessments at the onset, 3 and 6 months. The number of individuals still reporting pain at 6 months, and therefore qualifying for 'chronic pain', was considerably higher than expected (40%). At 6 months, the persisting pain problems were found to be moderate to severe in intensity in approx. 20% of cases. Despite the pain, the chronic sufferers showed gradual continuing adjustments to it, re-establishing activities despite pain. Most of the change in the pain components (cognitive, subjective, behavioral, depression, anxiety) occur in the first 3 months, after which considerable stability is evident in the residual problem. In contrast, the impact of the pain and the consequent disability decline more markedly and continue to do so right up to the 6 month point. There was no evidence of chronic pain evolving and growing, but rather of a persistence of the acute presentation. PMID:1835836

    2015-01-01

    Chronic muscle pain remains a significant source of suffering and disability despite the adoption of pharmacologic and physical therapies. Muscle pain is mediated by free nerve endings distributed through the muscle along arteries. These nerves project to the superficial dorsal horn and are transmitted primarily through the spinothalamic tract to several cortical and subcortical structures, some of which are more active during the processing of muscle pain than other painful conditions. Mechanical forces, ischemia, and inflammation are the primary stimuli for muscle pain, which is reflected in the array of peripheral receptors contributing to muscle pain-ASIC, P2X, and TRP channels. Sensitization of peripheral receptors and of central pain processing structures are both critical for the development and maintenance of chronic muscle pain. Further, variations in peripheral receptors and central structures contribute to the significantly greater prevalence of chronic muscle pain in females. PMID:24633937

    Oral opioids are the treatment of choice for chronic cancer pain. Morphine is the strong opioid of choice for the treatment of moderate to severe cancer pain according to guidelines from the World Health Organization (WHO). This recommendation by the WHO was derived from availability, familiarity to clinicians, established effectiveness, simplicity of administration, and relative inexpensive cost. It was not based on proven therapeutic superiority over other options. Patients who experience inadequate pain relief or intolerable side effects with one opioid may often be successfully treated with another agent or with the same agent administered by a different route. Opioid rotation, or switching to an alternative opioid, helps some patients achieve better pain control with fewer associated adverse effects. Oxycodone is a mu-opioid receptor specific ligand, with clear agonist properties. It is an active potent opioid, which is in part a kappa-receptor agonist. Like morphine and other pure agonists, there is no known ceiling to the analgesic effects of oxycodone. The active metabolites of oxycodone (eg, oxymorphone) could be important in oxycodone-mediated analgesia. The main pharmacokinetic difference between oxycodone and morphine is in oral bioavailability. The bioavailability of oxycodone is >60% and the bioavailability of morphine is 20%. Controlled-release oxycodone is absorbed in a bi-exponential fashion. There is a rapid phase with a mean half-life of 37 min, accounting for 38% of the dose, and a slow phase with a half-life of 6.2 h, which accounts for the residual 62%. Oxycodone elimination is impaired by renal failure because there are both an increased volume of distribution and reduced clearance. A lot of studies prove that the efficacy of controlled-release oxycodone in cancer-pain control is at least the same as morphine, immediate-release oxycodone and hydromorphone. Its toxicity profile seems better than that of morphine. There are actually several

    The role of personality in the experience of chronic pain is a growing field, with endless debate regarding the existence of a "pain personality". This study aims to compare different chronic pain types and consolidate the existence of a common personality. Thirty-two females with chronic orofacial pain and 37 age-matched healthy females were assessed with the Temperament and Character Inventory-Revised. Chronic pain subjects had either trigeminal neuropathy (neuropathic pain) or temporomandibular disorders (nociceptive pain). This study revealed that individuals with different chronic pain types exhibit a mutual personality profile encompassing significantly higher scores in Harm Avoidance and significantly lower scores in Self-Directedness when compared to healthy subjects. In fact, this combination is associated with Cluster C personality disorders. In conclusion, our study reveals that irrespective of type, chronic pain may be associated with Cluster C personality disorders. Indeed, there has never been empirical evidence in the past to suggest that chronic pain as an overall concept is associated with any particular personality disorders. Therefore, a potential future avenue of chronic pain treatment may lie in targeting particular personality aspects and shift the target of pain-relieving treatments from sensory and psychologically state focused to psychologically trait focused.

    Lumbar degenerative disc disease without disc herniation, also known as discogenic pain, is an elusive diagnosis of chronic low back pain. Lumbar provocation discography and fusion surgery have been frequently utilized for several decades as the gold standards for the diagnosis and treatment of symptomatic lumbar discogenic pain, though controversial, based on conjecture, rather than evidence. In addition to lumbar fusion, various other operative and nonoperative modalities of treatments are available in managing chronic lumbar discogenic pain. This review provides an updated assessment of the management of chronic lumbar discogenic pain with a critical look at the many modalities of treatments that are currently available. PMID:26255722

    As detailed in this online CME activity (www.cmeaccess.com/AJM/ChronicPain04), determining pain mechanism is an important aspect guiding treatment selection for chronic musculoskeletal pain states. Although broad classifications provide a framework, any combination of mechanisms may be present in a chronic pain patient, and there is growing evidence that pain states generally considered nociceptive may also involve elements of augmented central nervous system pain processing. Nonopioid analgesics, including serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, and alpha-2-delta ligand anticonvulsants, are the treatments of choice for fibromyalgia and other central neuropathic pain states. Additionally, studies have now shown that certain SNRIs can be effective in treating "classic" nociceptive pain states, such as osteoarthritis, and also are effective for low back pain. In addition to considering biological mechanisms, chronic pain management also involves recognizing and evaluating the contribution of psychological and sociocultural factors that can influence pain chronicity and patient prognosis. A multimodal/multidisciplinary approach incorporating pharmacologic and nonpharmacologic therapy into a program that includes more than 1 discipline is important to improve outcomes in patients with chronic pain.

    Purpose Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent urologic disorder among men, but its etiology is still poorly understood. Our objective was to examine the relationship between physical activity and incidence of CP/CPPS in a large cohort of male health professionals. Methods We conducted a prospective cohort study among men in the Health Professionals Follow-up Study followed from 1986 to 2008. The study population included 20,918 men who completed all CP/CPPS questions on the 2008 questionnaire. Leisure-time physical activity, including type and intensity of activity, was measured by questionnaire in 1986. A National Institute of Health Chronic Prostatitis Symptom Index pain score was calculated based on the responses on the 2008 questionnaire. Participants with pain scores ≥ 8 were considered CP/CPPS cases (n=689). Results Higher leisure-time physical activity was associated with lower risk of CP/CPPS. The multivariable-adjusted odds ratio (OR) comparing >35.0 to ≤3.5 MET-h/wk of physical activity was 0.72 (95% confidence interval (CI): 0.56, 0.92, p for trend <0.001). Observed inverse associations between physical activity and CP/CPPS were similar for both moderate- and vigorous-intensity activities. Sedentary behavior, measured as time spent watching television, was not associated with risk of CP/CPPS (p for trend 0.64). Conclusions Findings from this study, the first large scale and most comprehensive study to date on this association, suggest that higher levels of leisure-time physical activity may lower risk of CP/CPPS in middle-aged and older men.

    Chronic axial neck pain and cervicogenic headache are common problems, and there have been significant advances in the understanding of the etiology and treatment of each. The severity and duration of pain drives the process. For patients who have had slight to moderate pain that has been present for less than 6 months and have no significant motor loss, strength training of anterior, posterior, and interscapular muscle groups coupled with body mechanics training is prescribed. After 8 weeks, if the patient is better, exercises are continued at home or in a gym. If the patient is not better, physical therapy is continued for up to 8 more weeks. In patients with motor loss or severe pain, radiographs and magnetic resonance imaging (MRI) should be ordered at the initial visit. In patients with slight to moderate pain who are not better by 4 to 6 months, plain radiographs of the neck and MRI should be ordered. Based on the results, a spinal injection is usually prescribed. If MRI reveals spinal stenosis of the central or lateral canal, or a disc herniation, an epidural corticosteroid injection should be ordered. If the epidural provides good relief, the patient can be referred for more aggressive physical therapy and repeat the epidural as needed up to a maximum of three times. If there is no pathology within the canal, medial branch blocks and intra-articular steroid injections can be ordered based on the joints that are most tender or where disc space narrowing is greatest, or MRI or radiographs are recommended. If there is excellent relief from the medial branch block and joint injections, repeat when the steroids wear off. If there is good relief again, but pain recurs, medial branch radiofrequency neurotomy is recommended. For patients with one or two level disc degeneration that has not responded, a psychologic evaluation and discography is recommended. If there are no significant psychologic abnormalities, and one or two (rarely three) painful discs, surgical

    Pain is common as a presenting complaint to outpatient and emergency departments for children, yet pain management represents one of the children's largest unmet needs. A child may present with acute pain for an intermittent issue or may have acute or chronic pain in the setting of chronic illness. The mainstay of treatment for pain uses a stepwise approach for pain management, such as set up by the World Health Organization. For children with life-limiting illnesses, the Institute of Medicine guidelines recommends referral upon diagnosis for palliative care, meaning that the child receives comprehensive services that include pain control in coordination with curative therapies; yet barriers remain. From the provider perspective, pain can be better addressed through a careful assessment of one's own knowledge, skills, and attitudes. The key components of pain management in children are multimodal, regardless of the cause of the pain. PMID:23329083

    Pain is a complex and multidimensional perception, embodied in our daily experiences through interoceptive appraisal processes. The article reviews the recent literature about interoception along with predictive coding theories and tries to explain a missing link between the sense of the physiological condition of the entire body and the perception of pain in chronic conditions, which are characterized by interoceptive deficits. Understanding chronic pain from an interoceptive point of view allows us to better comprehend the multidimensional nature of this specific organic information, integrating the input of several sources from Gifford's Mature Organism Model to Melzack's neuromatrix. The article proposes the concept of residual interoceptive images (ghosts), to explain the diffuse multilevel nature of chronic pain perceptions. Lastly, we introduce a treatment concept, forged upon the possibility to modify the interoceptive chronic representation of pain through external input in a process that we call interoceptive modeling, with the ultimate goal of reducing pain in chronic subjects.

    Pain is a complex and multidimensional perception, embodied in our daily experiences through interoceptive appraisal processes. The article reviews the recent literature about interoception along with predictive coding theories and tries to explain a missing link between the sense of the physiological condition of the entire body and the perception of pain in chronic conditions, which are characterized by interoceptive deficits.

    Chronic pelvic pain in women is a key site through which explorations of the meanings of female gender and pain might further insights into the broader question of the embodied experience of women in relation to pain. A biocultural approach is used to present an analysis of interviews with 40 New Zealand women in which they reflect on 'how come' they have chronic pelvic pain. Women consistently employ a mechanistic rendition of medical discourse and understandings in their constructions of 'how come' they have pain, accompanied by a reiteration of 'not knowing' and a normalizing of their pelvic pain. We explore how this normalizing works within the narratives to establish women's pelvic pain as intrinsically gendered. Etiological meanings that are constructed in medical terms and yet are unable to be interpreted within a dualist frame of normality and pathology, we argue, permeate and shape gendered experience of chronic pain conditions.
