    SUMMARY Two hundred patients with chronic intractable pain have been evaluated in order to study the clinical characteristics of pain and associated psychiatric illnesses. The commonest site of pain was reported to be head and face, usually dull in nature. Almost 75% of patients reported continuous pain. A great majority (40%–80%) had some psycho-social problem or other problem resultant from the chronic pain. 72% patients had identifiable psychiatric illness, commonest being neurotic depression and anxiety states. The common symptoms reported on the Present State Examination (PSE) were worrying (77%), depression (40%), hypochondrical pre-occupation (35%), autonomic anxiety (42%) and irritability (40%). There is no specific clinical characteristic associated with any particular psychiatric diagnosis. The relevance of psychiatric symptoms and illness associated with chronic pain has been discussed.

    Spinal epidural neurostimulation, which evolved from dorsal column stimulation, has been found to be effective in the treatment of acute and chronic intractable pain. Urban and Hashold have shown that it is a safe, simplified alternative to dorsal column stimulation, especially because laminectomy is not required if the electrodes are inserted percutaneously. Percutaneous epidural neurostimulation is also advantageous because there can be a diagnostic trial period before permanent internalization and implantation. This diagnostic and therapeutic modality has been used in 36 patients during the past 3 years at Northwestern Memorial Hospital. Eleven of these patients had acute intractable pain, which was defined as pain of less than 1 year in duration. Initial postimplantation results from the 36 patients indicate that spinal epidural neurostimulation is most effective in treating the intractable pain of diabetes, arachnoiditis, and post-traumatic and postamputation neuroma. Long term follow-up, varying from 1 year to 3 years postimplantation in the 20 initially responding patients, indicates that the neurostimulation continues to provide significant pain relief (50% or greater) in a majority of the patients who experienced initial significant pain relief.

    Cryoanalgesia, the local application of extreme cold to nerves to produce analgesia, has been used to treat patients with intractable perineal pain. The cryoprobe was inserted percutaneously through the sacral hiatus into the sacral canal to produce anaesthesia of the lower sacral nerve roots. Forty patients received a total of 70 treatments: 31 patients (78%) were helped by the procedure and the median duration of improvement was 30 days. The treatment was more successful in relieving symptoms in patients suffering from pelvic cancer and coccydynia. The best results were obtained in those patients who received numerous freeze applications or prolonged freezing. Images Figure 1. PMID:7299782

    As many as 62% low back pain patients can have sacroiliac joint (SIJ) pain. There is limited (to poor) evidence in regards to long-term pain relief with therapeutic intra-articular injections and/or conventional (heat or pulsed) radiofrequency ablations (RFAs) for SIJ pain. We report our pain-clinic experience with peripheral nerve field stimulation (PNFS) for two patients of intractable SIJ pain. They had reported absence of long-term pain relief (pain relief >50% for at least 2 weeks postinjection and at least 3 months post-RFA) with SIJ injections and SIJ RFAs. Two parallel permanent 8-contact subcutaneous stimulating leads were implanted under the skin overlying their painful SIJ. Adequate stimulation in the entire painful area was confirmed. For implantable pulse generator placement, a separate subcutaneous pocket was made in the upper buttock below the iliac crest level ipsilaterally. During the pain-clinic follow-up period, the patients had reduced their pain medications requirements by half with an additional report of more than 50% improvement in their functional status. The first patient passed away 2 years after the PNFS procedure due to medical causes unrelated to his chronic pain. The second patient has been comfortable with PNFS-induced analgesic regimen during her pain-clinic follow-up during last 5 years. In summary, PNFS can be an effective last resort option for SIJ pain wherein conventional interventional pain techniques have failed, and analgesic medication requirements are escalating or causing unwarranted side-effects.

    As mast cells have been highlighted in the pathogenesis of diarrhea-predominant irritable bowel syndrome, a new term "mastocytic enterocolitis" was suggested by Jakate and colleagues to describe an increase in mucosal mast cells in patients with chronic intractable diarrhea and favorable response to treatment with antihistamines. Although it is not an established disease entity, two cases have been reported in the English medical literature. Here, for the first time in Asia, we report another case of chronic intractable diarrhea caused by gastrointestinal mastocytosis. The patient was a 70-year-old male with chronic intractable diarrhea for 3 months; the cause of the diarrhea remained obscure even after exhaustive evaluation. However, biopsy specimens from the jejunum were found to have increased mast cell infiltration, and the patient was successfully treated with antihistamines. PMID:27433151

    PubMed

    Russo, C M; Brose, W G

    1998-01-01

    Chronic pain is an emotional experience and is defined as pain lasting greater than six months. It is important to understand the neurophysiology of pain in order to treat it. Nociceptors in the periphery travel to the substantia gelatinosa of the spinal cord while secondary and tertiary afferents transmit information from the dorsal horn to the brain. Modification of pain information may take place in these ascending pathways or in descending pathways. Treatment of chronic pain is most successful when it is approached in a multidisciplinary fashion with the focus not only on treatment of underlying etiology, but also on the secondary impacts of pain on the patient's life. The management of chronic pain requires special expertise. Most of the experts in chronic pain assessment and management organize themselves into pain treatment centers. These centers vary widely in their approach to the problem. The most sophisticated is a multidisciplinary center that is university-based and includes teaching and research. Treatment of chronic pain includes a variety of medications, psychological support, and rehabilitation. Multidisciplinary pain management is also an integral part of the palliative care and hospice concept used to treat cancer pain.

    Intracerebroventricular (ICV) administration of opioids for control of intractable cancer pain has been used since 1982. We present here our experience of intracerebroventricular administration of pain treatments including ziconotide associated with morphine and ropivacaine for patients resistant to a conventional approach, with nociceptive, neuropathic, or mixed pain. These clinical cases were conducted with patients suffering from refractory pain, more than 6/10 on a numerical pain rating scale (NPRS) while on high-dose medical treatment and/or intolerance with significant side effects from oral medication. The baseline study visit included a physical examination and an assessment of pain intensity on a NPRS. Under general anesthesia, a neuronavigation device was used to place the catheter on the floor of the third ventricle, supported by an endoscope. Then, drugs were injected in the cerebroventricular system, through a pump (external or subcutaneous). The primary objective was to measure pain evaluation with ICV treatment after a complete withdrawal of other medications.Four patients were enrolled: 3 with intractable cancer pain and one with central neuropathic pain. The median NPRS at baseline was 9.5 [8.5; 19]. The mean NPRS after one month was 3.5 [3; 4.5]. Ziconotide was initiated at 0.48 µg/d and up to a median of 1.2 µg/d [1.0; 1.56]. The median dose of morphine and ropivacaine used initially was respectively 0.36 mg/d [0.24; 0.66] up to 0.6 mg/d [0.45; 4.63] and 1.2 mg/d [0; 2.4] up to 2.23 mg/d [1.2; 3.35]. Minor side effects were initially observed but transiently. One psychiatric agitation required discontinuation of ziconotide infusion. For intractable pain, using ziconotide by intracerebroventricular infusion seems safe and efficient, specifically for chronic neoplastic pain of cervicocephalic, thoracic, or diffuse origin and also for pain arising from a central neuropathic mechanism.

    Haemangiomas are tumours of vascular origin accounting for approximately 7 % of all benign tumours. Three types of haemangioma have been described according to the vessel type involved: capillary, cavernous and mixed. Intramuscular haemangiomas (IMHs) are infrequent, accounting for less than 1 % of all haemangiomas and are mostly located in the extremities and the trunk. Intramuscular haemangiomas of the rectus abdominis muscle are extremely rare, with only one previous case reported in the literature to the best of our knowledge. In this report, we present the case of a patient with intractable pain related to IMHs of the rectus abdominis and we analyse diagnostic assessment and surgical management of the condition.

    Objective To evaluate the beneficial effect of botulinum toxin A (Botox) injection into the subscapularis muscle on intractable hemiplegic shoulder pain. Methods Six stroke patients with intractable hemiplegic shoulder pain were included. Botulinum toxin A was injected into the subscapularis muscle. Intractable hemiplegic shoulder pain was evaluated using an 11-point numerical rating scale. Pain-free range of motion was assessed for shoulder abduction and external rotation. The spasticity of the shoulder internal rotator was measured using the modified Ashworth scale. Assessments were carried out at baseline and at 1, 2, 4, and, if possible, 8 weeks. Results Intractable hemiplegic shoulder pain was improved (p=0.004) after botulinum toxin injection into the subscapularis muscle. Restricted shoulder abduction (p=0.003), external rotation (p=0.005), and spasticity of the shoulder internal rotator (p=0.005) were also improved. Improved hemiplegic shoulder pain was correlated with improved shoulder abduction (r=–1.0, p<0.001), external rotation (r=–1.0, p<0.001), and spasticity of the internal rotator (r=1.0, p<0.001). Conclusion Botulinum toxin A injection into the subscapularis muscle appears to be valuable in the management of intractable hemiplegic shoulder pain.

Moderately good relief of pain was obtained with a combination of phenothiazines (especially pericyazine), antidepressant drugs and antihistamines. The theoretical implications of this are discussed and it is suggested that the drugs in question act partly by virtue of an effect on the multisynaptic neuronal systems whose activities are related to the experience of pain.

    2011-12-01

    Cryoanalgesia is a controversial adjunct to the management of chronic pain, but we know of no studies that have investigated its effect in the management of temporomandibular joint (TMJ) pain. In this five-year retrospective study we treated 17 patients who had severe pain that had failed to respond to all forms of conventional conservative treatment and were not appropriate for simple open operation. None had a clear indication for open operation on the joint or had too severe disease to warrant a simple procedure. Preliminary diagnostic injections of bupivacaine to the TMJ relieved the pain. We applied the cryoprobe in the region of the auriculotemporal nerve and TMJ capsule. There was a small but insignificant improvement in mean mouth opening together with a significant (p=0.000) improvement in visual analogue pain scores (VAS) from 6.8 (range 4-10) to 2.0 (range 0-7). Two patients had no change in their pain scores, and 2 had complete resolution of their pain. The mean number of pain-free months after treatment was 7 (IQR 3-15). Three patients had long-term pain relief, and 12 temporary relief; 6 of these subsequently had successful relief after total replacement of the TMJ. One patient had further cryoanalgesia, one was referred for specialist pain management, and one controlled the pain with nortriptyline. Of the 17 cases studied, 2 had temporary complications after cryoanalgesia. Cryoanalgesia is a useful adjunct to the management of intractable pain in the TMJ. Short-term pain relief can be achieved, and long-term relief is possible in some, deferring more complex and costly treatments. PMID:21177004

    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

Putative risk factors for CPSP include genetic predisposition, demographic, clinical (pain history, type of surgery, anaesthesia, acute pain severity), and psychological factors (vulnerability vs resilience). Evidence of prevention is limited: long-term benefit from pre-emptive/perioperative analgesia has not been demonstrated consistently. Large scale prospective studies with detailed pre, intra and postoperative multifactorial assessments are required to refine understanding of the aetiology and prognosis of CPSP. PMID:26526062

    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

    In this paper the chronicity of pain in non-specific pain syndromes is discussed. Experts in the study of pain with several professional backgrounds in rehabilitation are the authors of this paper. Clinical experience and literature form the basis of the paper. Non-specific low back pain and Complex Regional Pain Syndrome type I (CRPS-I) are discussed in the light of chronic pain. Many definitions of chronic pain exist. Yellow flags are important factors to identify possible chronic pain. In the acute phase of a non-specific pain complaint one should try to identify possible psychosocial inciting risk factors. Behavioural and cognitive treatment seems to be effective for chronic pain patients. PMID:16492632

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.

    Pain is frequent in communicative or no-communicative, ambulatory, institutionalized or hospitalized veterans. It is associated with severe comorbidity so much more than chronic pain could be neglected and expressed of atypical manner or masked by the absence of classical symptoms in particular in case of dementia or of sensory disorders. Pain detection by clinic examination or by pain assessment's methods and adequate approach by pharmacological and non pharmacological therapies are essential for correct pain management. On pharmacological plan, the strategy of the O.M.S. landings is applicable owing to a more particular attention to secondary effects and drugs interactions. AINS must be manipulated with prudence. There are no reasons to exclude opioides from the therapeutic arsenal but with a reduction of the starting doses, a regular adaptation and a very attentive survey. In drugs of landing 2, tramadol reveals itself as efficient and better tolerated as the codeine and dextropropoxyphene has to be to avoid. The obtaining of a satisfactory result depends on a regular assessment of the pain in a context of polydisciplinar approach (physicians, nurses, paramedicals, other care givers).

    There are patients who suffer from persistent dentoalveolar pain disorder (PDAP) which is a pain of the teeth, either dentoalveolar pain or nonodontogenic toothache, and its cause has not yet been identified. An effective intervention for PDAP has not yet been established. Interventions for patients with PDAP are generally pharmacological treatments such as antidepressants, anticonvulsants, and pregabalin. However, these medicines are not always effective for patients. The pain disorder in the orofacial region including temporomandibular disorder (TMD) and PDAP was effectively treated with our original exercise therapy. However, we did observe some intractable cases of PDAP even when our original exercise therapy was used. This paper presents our findings in which Kamishoyosan improved the pain intensity in 14 out of 15 PDAP patients refractory to our original exercise therapy. PMID:26495024

    Chronic noncancer pain is highly prevalent with associated negative effects on function and quality of life of the individuals involved. Opioids have been shown to decrease pain and improve function in some patients with chronic noncancer pain, but they are not always effective and are associated with multiple complications, including drug misuse, abuse and diversion. Furthermore, the effectiveness of opioids in decreasing pain and improving function has not been proven conclusively, resulting in continued uncertainty about long-term benefits of opioids for chronic noncancer pain. Ideally, in modern medicine, clinical decisions are made based on information derived from high quality evidence. Since no such evidence exists for chronic opioid therapy in chronic noncancer pain, this review describes various aspects of opioid therapy in chronic noncancer pain, including adherence monitoring, along with a ten-step process outlining the principles of effective and safe opioid use.

    Background Unacceptable adverse effects, contraindications to and/or ineffectiveness of World Health Organization step III “pain ladder” drugs causes needless suffering among a population of cancer patients. Successful management of severe cancer pain may require invasive treatment. However, a patient’s refusal of an invasive procedure necessitates that clinicians consider alternative options. Objective Intrathecal bupivacaine delivery as a viable treatment of intractable pain is well documented. There are no data on rectal bupivacaine use in cancer patients or in the treatment of cancer tenesmoid pain. This study aims to demonstrate that bupivacaine administered rectally could be a step in between the current treatment options for intractable cancer pain (conventional/conservative analgesia or invasive procedures), and to evaluate the effect of the mode of administration (intrathecal versus rectal) on the bupivacaine plasma concentration. Cases We present two Caucasian, elderly inpatients admitted to hospice due to intractable rectal/tenesmoid pain. The first case is a female with vulvar cancer, and malignant infiltration of the rectum/vagina. Bupivacaine was used intrathecally (0.25–0.5%, 1–2 mL every 6 hours). The second case is a female with ovarian cancer and malignant rectal infiltration. Bupivacaine was adminstered rectally (0.05–0.1%, 100 mL every 4.5–11 hours). Methods Total bupivacaine plasma concentrations were determined using the high-performance liquid chromatography-ultraviolet method. Results Effective pain control was achieved with intrathecal bupivacaine (0.077–0.154 mg·kg−1) and bupivacaine in enema (1.820 mg·kg−1). Intrathecal bupivacaine (0.5%, 2 mL) caused a drop in blood pressure; other side effects were absent in both cases. Total plasma bupivacaine concentrations following intrathecal and rectal bupivacaine application did not exceed 317.2 ng·mL−1 and 235.7 ng·mL−1, respectively. Bupivacaine elimination was

    Almost 10% of the adult male population suffer from prostatitis. The International Prostatitis Collaborative Network has devised and validated a clinically useful classification of prostatitis that urologists and primary care clinicians will find helpful. According to this schema, chronic bacterial prostatitis is clearly an infectious disease, and patients with chronic prostatitis associated with chronic pelvic pain syndrome can have either inflammatory or noninflammatory disease. Chronic bacterial prostatitis is uncommon, chronic nonbacterial prostatitis (CPPS) is extremely common. Antibiotic therapy is indicated in management of chronic bacterial prostatitis and inflammatory chronic pelvic pain syndrome. Fluoroquinolones are safe and effective in managing chronic bacterial prostatitis. Based on literature, noninflammatory chronic pelvic pain syndrome can be treated using adrenergic blockade, analgesic, tricyclic antidepressants, benzodiazepie, physical therapy. PMID:12556633

    2015-05-01

    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.

    2014-02-01

    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.

    Chronic intractable pain is a common problem in severe pancreatic disease. Bilateral thoracoscopic splanchnotomy, a thoracoscopic neurotomy of the splanchnic nerves, is rarely performed but may provide significant pain relief in these patients. We present a safe strategy that uses prone positioning and two thoracoscopic ports for either hemithorax, permitting easy exposure and simple dissection of the greater and lesser splanchnic nerves. In our experience, this technique provides excellent pain relief with a minimal postoperative stay and few postoperative adverse events. This intervention has the potential to reduce dependency on opioid agents and improve quality of life in carefully selected patients. PMID:26897240

    Chronic pain, especially chronic back pain, is costly to workers, their families, employers, and society. Successful return to productive work life for the worker with chronic pain requires multi-disciplinary efforts, including those of the nurse case manager, occupational health nurse, and nursing specialist in pain management. Sensitivity to the dynamics of multiple stakeholders in the RTW process is essential because of their diverse perspectives. Successful RTW can be facilitated by a combination of approaches, including case management, worker capacity evaluation, ergonomic job analysis, team design of job modifications, appropriate medical treatment, and self management by the worker.

    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.

    2015-01-01

    Unlike acute pain that warns us of injury or disease, chronic or persistent pain serves no adaptive purpose. Though there is no agreed on definition of chronic pain, it is commonly referred to as pain that is without biological value, lasting longer than the typical healing time, not responsive to treatments based on specific remedies, and of a duration greater than 6 months. Chronic pain that is severe and intractable has detrimental consequences, including psychological distress, job loss, social isolation, and, not surprisingly, it is highly comorbid with depression and anxiety. Historically, pain without an apparent anatomical or neurophysiological origin was labelled as psychopathological. This approach is damaging to the patient and provider alike. It pollutes the therapeutic relationship by introducing an element of mutual distrust as well as implicit, if not explicit, blame. It is demoralizing to the patient who feels at fault, disbelieved, and alone. Moreover, many medically unexplained pains are now understood to involve an interplay between peripheral and central neurophysiological mechanisms that have gone awry. The new Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, somatic symptom disorder overpsychologizes people with chronic pain; it has low sensitivity and specificity, and it contributes to misdiagnosis, as well as unnecessary stigma. Adjustment disorder remains the most appropriate, accurate, and acceptable diagnosis for people who are overly concerned about their pain. PMID:26174215

    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

    Phantom limb pain is a phenomenon in which patients experience pain in a part of the body that no longer exists. In several treatment modalities, spinal cord stimulation (SCS) has been introduced for the management of intractable post-amputation pain. A 46-year-old male patient complained of severe ankle and foot pain, following above-the-knee amputation surgery on the right side amputation surgery three years earlier. Despite undergoing treatment with multiple modalities for pain management involving numerous oral and intravenous medications, nerve blocks, and pulsed radiofrequency (RF) treatment, the effect duration was temporary and the decreases in the patient's pain score were not acceptable. Even the use of SCS did not provide completely satisfactory pain management. However, the trial lead positioning in the cauda equina was able to stimulate the site of the severe pain, and the patient's pain score was dramatically decreased. We report a case of successful pain management with spinal cauda equina stimulation following the failure of SCS in the treatment of intractable phantom limb pain. PMID:27103968

    Phenytoin is an anti-convulsant and anti-arrhythmic medication. Manufactured by various pharmaceutical companies with various brand names, phenytoin (PHT) is also known as Dilantain, Hydantoin or Phenytek in the United States; Dilantain or Remytoine in Canada; Epamin, Hidantoina in Mexico; and Fenidatoin or Fenitron or other names elsewhere in the world. Phenytoin (PHT) is especially useful for patients suffering from intractable oral and facial pain especially those who exhibit anger, stress, depression and irrational emotions commonly seen in the patients with oral and facial pain. When used properly, Phenytoin is also an effective anxiolysis drug in addition to its theraputic effects on pain and can be used alone or, even better, if combined with other compatible sedatives. Phenytoin is particularly valuable when combined with acupuncture for patients with trigeminal neuralgia, glossopharyneal neuralgia, Bell's palsy, and some other facial paralysis and pain. It also has an advantage of keeping the patient relatively lucid after treatment. Either PHT or acupuncture alone can benefit patients but the success of treatment outcome may be limited. We found by combining both acupuncture and PHT with Selective Drug Uptake Enhancement by stimulating middle finger at the first segment of ventral (palmar) and lateral surfaces, as well as prescribing PHT with the dosage predetermined for each patient by Bi-Digital O-Ring Test (BDORT), the treatment outcome was much better resulted with less recurrence and intensity of pain during episodes of attack. Patients with Bell's palsy were most benefited by acupuncture therapy that could completely get rid of the illness. PMID:21830351

    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 non-steroidal anti-inflammatory drugs. Inflammation-, tissue injury-, and/or nerve injury-induced changes in gene expression in sensory neurons of the dorsal root ganglion (DRG), 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 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

    Chronic pain is a multifactorial condition with both physical and psychological symptoms, and it affects around 20% of the population in the developed world. In spite of outstanding advances in pain management over the past decades, chronic pain remains a significant problem. This article provides a mechanism- and evidence-based approach to improve the outcome for pharmacologic management of chronic pain. The usual approach to treat mild to moderate pain is to start with a nonopioid analgesic. If this is inadequate, and if there is an element of sleep deprivation, then it is reasonable to add an antidepressant with analgesic qualities. If there is a component of neuropathic pain or fibromyalgia, then a trial with one of the gabapentinoids is appropriate. If these steps are inadequate, then an opioid analgesic may be added. For moderate to severe pain, one would initiate an earlier trial of a long term opioid. Skeletal muscle relaxants and topicals may also be appropriate as single agents or in combination. Meanwhile, the steps of pharmacologic treatments for neuropathic pain include (1) certain antidepressants (tricyclic antidepressants, serotonin and norepinephrine reuptake inhibitors), calcium channel alpha(2)-delta ligands (gabapentin and pregabalin) and topical lidocaine, (2) opioid analgesics and tramadol (for first-line use in selected clinical circumstances) and (3) certain other antidepressant and antiepileptic medications (topical capsaicin, mexiletine, and N-methyl-d-aspartate receptor antagonists). It is essential to have a thorough understanding about the different pain mechanisms of chronic pain and evidence-based multi-mechanistic treatment. It is also essential to increase the individualization of treatment. PMID:20556211

    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.

    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

    Transverse myelitis is a rare inflammatory myelopathy characterized by loss of motor and sensory function below the affected level of the spinal cord, and causes neurogenic bowel and bladder. Occasionally, it also causes neuropathic pain with spasticity. Traditional therapies for neuropathic pain are multiple, including multimodal analgesic regimens, antiepileptic or antidepressant medications, opioids, sympathetic blocks, and spinal cord stimulation. Persistent neuropathic pain can cause emotional distress by affecting sleep, work, recreation, and emotional well-being. Here we report the case of a patient suffering from intractable neuropathic pain following acute transverse myelitis that was not relieved by combinations of nonsteroidal anti-inflammatory, anti-epileptic, antidepressant, and opioid medications, or by acupuncture. Implantation of an intrathecal morphine pump controlled the pain successfully without side effects, and enabled the patient to embark on intensive rehabilitation. The patient’s muscle strength has improved significantly and the patient may soon be able to use a walker with minimal assistance. PMID:23935366

    Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p < 0.05). There were no between group differences in heat pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

    2014-03-01

    Chronic pain, most often due to haemophilic arthropathy, is a pervasive problem in persons with haemophilia (PWH) that adversely impacts function and quality of life. PWH with inhibitors and older PWH may be especially vulnerable to progressive arthropathy and resulting chronic pain. The development of chronic pain from acute pain involves a complex interplay of biological and psychosocial factors that may all contribute to the perpetuation of chronic pain and the outcome of therapy. In the absence of evidence-based guidelines, an individualized, multimodal approach to chronic pain management is proposed, as it is in individuals without haemophilia who have chronic pain. Pharmacological treatment is central to the management of chronic pain and must be modified based on pain intensity, ongoing response to therapy and the risk for adverse events. Non-pharmacological interventions, including physiotherapy, complementary treatments and surgical (e.g. orthopaedic) or other invasive procedures, may be integral to chronic pain management in this population. Ongoing psychosocial assessment is critical to identify those factors that may be contributing to the perpetuation of chronic pain or acting as barriers to effective management. Additional study is needed to identify optimal pharmacological treatments for chronic pain in PWH based on the unique pathophysiology of haemophilic arthropathy and on risk profile. Systematic determination of the particular psychosocial factors impacting the experience and management of chronic pain in PWH would likewise add value to the treatment of this pervasive problem.

    We present the case of a 76 year old female inpatient who suffered from a chronic intractable cough which arose simultaneously to a severe major depression and was secondary to an exorbitant psychological distress. Chronic cough had never been experienced before and was initially considered to have a mere psychogenic origin since a comprehensive and guideline-based diagnostic screening did not reveal any underlying somatic cause. However, several factors cast doubt on the solitary psychic genesis of the chronic cough: i) occurrence immediately after a penetrant cold, ii) embedding in other complaints of laryngeal hyperreagibility (larynx irritable), such as persistent globus pharyngeus sensation, throat clearing and episodic dysphonia, iii) first occurrence on old life, iv) erupting from sleep as well, v) persistence despite remission of the major depression, and v) no sustaining benefit from specific psychotherapy and speech therapy. Therefore, diagnostics were extended to apparative tools for objective evaluation of swallowing by using fiberoptic videoendoscopic (FEES) and videofluoroscopic (VFS) techniques, which revealed signs of laryngeal neuropathy but without evidence of penetration or aspiration. A co-existing small goiter and an impaired glucose tolerance along with a putative intracellular vitamin B12 or folate deficiency (as indirectly derived from an apparent hyperhomocysteinemia) were assumed to be responsible for the neuropathy and underwent specific treatments. The impaired glucose tolerance and putative vitamin deficit were compatible with a distal symmetric sensorimotoric, even subclinical polyneuropathy of the lower extremities. The larynx irritable improved under gabapentin being confirmed by drug removals several times, and finally calmed down almost completely under gabapentin, which was in line with the scant literature of this topic. Re-examination of the larynx per FEES nine months later showed no deficits any more under the well

    Chronic heart failure (HF) is considered to be refractory when persisting despite an intensive drug regimen, or intractable when requiring "artificial" supports. Among them, hemofiltration (HE) has been used frequently, but only on an "acute" basis, to induce fast and safe water removal. Since 1985 the authors have treated refractory and intractable HF first by means of acute CAVH (continuous arteriovenous HE: 11 patients) and then (1988-1992) with IVVH (intermittent venovenous HE), initially done on an "acute" basis (13 patients) and then an a chronic basis (CIVVH): 8 subjects (6M, 2F; mean age, 60.8 years), 3 with RCHF and 5 with ICHF. This report deals with our experience in CIVVH. All patients were in severe failure. During a follow-up period of 63 months (range, 1-17/patient), 82 IVVH treatments (10.2/patient) were carried out, using this schedule: permanent Tesio catheter in superior vena cava, 0.6 m2 filter, double blood pump (blood flow = 80-250 ml/min); transmembrane pressure = 50-150 mmHg; mean ultrafiltration = 19 ml/min; replacement fluid = 8.6 ml/min; and session time = 340 +/- 88 min, according to individual dry weight (bioimpedance system). Six patients died (1-13 months after IVVH began); four of six had ICHF and two of six had RCHF; five of eight patients showed a significant amelioration of functional state, changing from fourth to third, to second and first degree failure, but this was after heart transplantation. In all cases a marked reduction in the drug regimen and in hospitalization was the rule. PMID:1457943

    2005-01-01

    The comorbidity integrated by chronic pain and depression is very common. The somatoform depressive symptoms appear often as diferent types of pain. Amon them premenstrual pain and fibromialgia are some of the most important clinical pictures. Chronic pain leads to depression as a consequence of these three kinds of factors: biomedical, psychosocial (passive attitude, disability) and pharmacological agents. Copping and acceptance of chronic pain is associated with lower pain intensity, less depression and less psychosocial disability. The appropriate use of analgesics in the management of chronic pain demands individualization. Several antidepressants have possitive effects on pain syndrom. Depression is underrecognized ad undertreated above all in patients with chronic pain. In order screening the depression seven ways are described here: personal and family history, type of the personality, clinic and evolutive aspects of somatoform symptom, search of other depressive symptoms and positive therapeutic effect determinated by an antidepressant.

  5. Psychological Aspects of Chronic Musculoskeletal Pain

    2015-01-01

    Chronic musculoskeletal pain, by its very nature, will be associated with negative emotions and psychological distress. There are individual differences in personality, coping skills, behavioral adaptation, and social support that dramatically alter the psychological outcomes of patients with chronic pain. Patients that have an aspect of central pain amplification associated with mechanical or inflammatory pain and patients with fibromyalgia (FM) are likely to exhibit higher levels of psychological distress and illness behaviors. This manuscript will discuss several different constructs for the association between chronic pain, central pain amplification, and psychological distress. The first key question addresses mechanisms shared in common between chronic pain and mood disorders, including the individual factors that influence psychological comorbidity. Second, how pain affects mood and vice versa. Finally, the utility of cognitive behavioral approaches to the management of chronic pain symptoms will be discussed. PMID:26267008

  6. Opioids for chronic noncancer pain

    PubMed Central

    2015-01-01

    The recent American Academy of Neurology position paper by Franklin, “Opioids for chronic noncancer pain,” suggests that the benefits of opioid treatment are very likely to be substantially outweighed by the risks and recommends avoidance of doses above 80–120 mg/day morphine equivalent. However, close reading of the primary literature supports a different conclusion: opioids have been shown in randomized controlled trials (RCTs) to be highly effective in the treatment of chronic nonmalignant pain; long-term follow-up studies have shown that this effectiveness can be maintained; and effectiveness has been limited in many clinical trials by failure to take into account high variability in dose requirements, failure to adequately treat depression, and use of suboptimal outcome measures. Frequency of side effects in many RCTs has been inflated by overly rapid dose titration and failure to appreciate the high interindividual variability in side effect profiles. The recent marked increase in incidence of opioid overdose is of grave concern, but there is good reason to believe that it has been somewhat exaggerated. Potential causes of overdose include inadequately treated depression; inadequately treated pain, particularly when compounded by hopelessness; inadvertent overdose; concurrent use of alcohol; and insufficient practitioner expertise. Effective treatment of pain can enable large numbers of patients to lead productive lives and improve quality of life. Effective alleviation of suffering associated with pain falls squarely within the physician's professional obligation. Existing scientific studies provide the basis for many improvements in pain management that can increase effectiveness and reduce risk. Many potentially useful areas of further research can be identified. PMID:26138946

    2011-01-01

    The transition from acute to chronic musculoskeletal pain is not well understood. To understand this transition, it is important to know how peripheral and central sensitization are manifested and how they can be assessed. A variety of human pain biomarkers have been developed to quantify localized and widespread musculoskeletal pain. In addition, human surrogate models may be used to induce sensitization in otherwise healthy volunteers. Pain can arise from different musculoskeletal structures (e.g. muscles, joints, ligaments, or tendons), and differentiating the origin of pain from those different structures is a challenge. Tissue specific pain biomarkers can be used to tease these different aspects. Chronic musculoskeletal pain patients in general show signs of local/central sensitization and spread of pain to degrees which correlate to pain intensity and duration. From a management perspective, it is therefore highly important to reduce pain intensity and try to minimize the duration of pain. PMID:23115471

    We introduce an intradural approach to spinal cord stimulation for the relief of intractable pain, and describe the biophysical rationale that underlies its design and performance requirements. The proposed device relies on wireless, inductive coupling between a pial surface implant and its epidural controller, and we present the results of benchtop experiments that demonstrate the ability to transmit and receive a frequency-modulated 1.6 MHz carrier signal between micro-coil antennae scaled to the ≈ 1 cm dimensions of the implant, at power levels of about 5 mW. Plans for materials selection, microfabrication, and other aspects of future development are presented and discussed.

    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.

    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

    Background Surgical injury can frequently lead to chronic pain. Despite the obvious importance of this problem, the first publications on chronic pain after surgery as a general topic appeared only a decade ago. This study tests the hypothesis that chronic postsurgical pain was, and still is, represented insufficiently. Methods We analyzed the presentation of this topic in journal articles covered by PubMed and in surgical textbooks. The following signs of insufficient representation in journal articles were used: (1) the lack of journal editorials on chronic pain after surgery, (2) the lack of journal articles with titles clearly indicating that they are devoted to chronic postsurgical pain, and (3) the insufficient representation of chronic postsurgical pain in the top surgical journals. Results It was demonstrated that insufficient representation of this topic existed in 1981–2000, especially in surgical journals and textbooks. Interest in this topic began to increase, however, mostly regarding one specific surgery: herniorrhaphy. It is important that the change in the attitude toward chronic postsurgical pain spreads to other groups of surgeries. Conclusion Chronic postsurgical pain is still a neglected topic, except for pain after herniorrhaphy. The change in the attitude toward chronic postsurgical pain is the important first step in the approach to this problem. PMID:23152698

    Objectives Catastrophizing is often the primary target of the cognitive-behavioral treatment of chronic pain. Recent literature on acceptance and commitment therapy (ACT) suggests an important role in the pain experience for the concepts mindfulness and acceptance. The aim of this study is to examine the influence of mindfulness and general psychological acceptance on pain-related catastrophizing in patients with chronic pain. Methods A cross-sectional survey was conducted, including 87 chronic pain patients from an academic outpatient pain center. Results The results show that general psychological acceptance (measured with the AAQ-II) is a strong predictor of pain-related catastrophizing, independent of gender, age and pain intensity. Mindfulness (measured with the MAAS) did not predict levels of pain-related catastrophizing. Discussion Acceptance of psychological experiences outside of pain itself is related to catastrophizing. Thus, acceptance seems to play a role in the pain experience and should be part of the treatment of chronic pain. The focus of the ACT treatment of chronic pain does not necessarily have to be on acceptance of pain per se, but may be aimed at acceptance of unwanted experiences in general. Mindfulness in the sense of “acting with awareness” is however not related to catastrophizing. Based on our research findings in comparisons with those of other authors, we recommend a broader conceptualization of mindfulness and the use of a multifaceted questionnaire for mindfulness instead of the unidimensional MAAS.

    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

    2000-01-01

    New developments in brain imaging lead to a better understanding of cortical and subcortical processes involved in pain perception and the establishment of chronic pain. For different forms of chronic pain long-term changes in cortical structures have been described. In patients with phantom limb pain and back pain alterations in the somatotopic organization of the primary somatosensory (SI) could be observed. The amount of this reorganization is correlated with the subjective pain rating. These changes, which are based on processes of neuronal plasticity, can partially be reversed by analgesic interventions. For the investigation of cortical processes concerning reorganization, EEG and MEG methods are most suitable because of their high temporal and spatial resolution. In conclusion, these findings open a new way for therapeutic interventions to prevent the development of chronic pain.

    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

    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.

    A preliminary report is presented on the results achieved in the assessment and treatment of patients with intractable pain during the first six months experience gained following the appointment of a pain consultant at the Ludwig Boltzmann Institute of Clinical Oncology. Nerve blockade was carried out 106 times in 45 patients suffering from primary or secondary malignant disease and 71 times in 18 patients with other conditions; intrathecal instillation of 96% alcohol was performed once and 2 chordotomies were also performed. One patient needed antidepressive therapy. Major questions relating to this problem are discussed. Gratifyingly satisfactory results were observed in more than two thirds of the patients. These objective findings and the subjective impressions obtained from patients, their relatives and our personnel prompted us to continue with this type of treatment for pain and to increase our efforts in this direction.

    The application of operant learning theory on chronic pain by Fordyce has had a huge impact on chronic pain research and management. The operant model focuses on pain behaviors as a major component of the pain problem, and postulates that they are subject to environmental contingencies. The role of operant learning in pain behaviors generally has been supported by experimental studies, which are reviewed in the present article. Subsequently, the rationale, goals, and methods of operant behavioral treatment of chronic pain are outlined. Special attention is paid to three therapeutic techniques (graded activity, activity pacing, and time-contingent medication management), which are discussed in detail with regard to their operationalization, effectiveness, and (possible) mechanisms of action. Criticisms of the operant model are presented, as are suggestions for the optimization of (operant) behavioral treatment efficacy.

    Although myofascial pain has often been described as being associated with psychosocial stress, detailed evidence in support of this assumption, either from standardized clinical examination or from validated chronic stress questionnaires, is absent. The hypothesis of the present study was that some stressors lead to higher scores in patients suffering from chronic myofascial pain than in pain-free controls and in patients suffering from chronic facial pain. One hundred and fifty subjects were included in the study, and depending on clinical findings, divided into three groups: exclusively chronic myofascial pain group, controls with chronic facial pain but without temporomandibular disorders (TMD), and controls without pain or TMD. Chronic stress was assessed on nine subscales by use of a validated questionnaire. Myofascial pain patients have a significantly higher stress score for "social isolation" than pain-free controls (t-test, p = 0.003). However, they do not have higher scores than patients suffering from facial pain (t test, p = 0.169). Thus, the hypothesis of this study could not be completely rejected. PMID:19705168

    Summary Chronic pain is a public health concern affecting 20–30% of the population of Western countries. Although there have been many scientific advances in the understanding of the neurophysiology of pain, precisely assessing and diagnosing a patient's chronic pain problem is not straightforward or well-defined. How chronic pain is conceptualized influences how pain is evaluated and the factors considered when making a chronic pain diagnosis. There is no one-to-one relationship between the amount or type of organic pathology and pain intensity, but instead, the chronic pain experience is shaped by a myriad of biomedical, psychosocial (e.g. patients' beliefs, expectations, and mood), and behavioural factors (e.g. context, responses by significant others). Assessing each of these three domains through a comprehensive evaluation of the person with chronic pain is essential for treatment decisions and to facilitate optimal outcomes. This evaluation should include a thorough patient history and medical evaluation and a brief screening interview where the patient's behaviour can be observed. Further assessment to address questions identified during the initial evaluation will guide decisions as to what additional assessments, if any, may be appropriate. Standardized self-reported instruments to evaluate the patient's pain intensity, functional abilities, beliefs and expectations, and emotional distress are available, and can be administered by the physician, or a referral for in depth evaluation can be made to assist in treatment planning.

There is no one-to-one relationship between the amount or type of organic pathology and pain intensity, but instead, the chronic pain experience is shaped by a myriad of biomedical, psychosocial (e.g. patients' beliefs, expectations, and mood), and behavioural factors (e.g. context, responses by significant others). Assessing each of these three domains through a comprehensive evaluation of the person with chronic pain is essential for treatment decisions and to facilitate optimal outcomes. This evaluation should include a thorough patient history and medical evaluation and a brief screening interview where the patient's behaviour can be observed. Further assessment to address questions identified during the initial evaluation will guide decisions as to what additional assessments, if any, may be appropriate. Standardized self-reported instruments to evaluate the patient's pain intensity, functional abilities, beliefs and expectations, and emotional distress are available, and can be administered by the physician, or a referral for in depth evaluation can be made to assist in treatment planning.

    Central aspects in the prevention of pain from becoming chronic are good management of acute pain, early recognition of risk factors and a multidisciplinary working approach. Postherpetic neuralgia can probably be prevented with a vaccine and medication. In the prevention of prolonged postoperative pains there is some evidence of the effect of local anesthetics and ketamine, but their clinical significance is unclear. Multidisciplinary therapeutic and rehabilitative actions can be taken to prevent prolongation and recurrence of lower back pain especially in patients having an increased risk of chronic pain.

    Although almost all infants suffering chronic subdural hematomas (CSDH) are successfully treated by established methods such as a subdural puncture, burr holes and shunting procedures, infantile CSDH with progressive craniocerebral disproportion requires a special therapeutical regimen. Clinical efforts such as reduction cranioplasty have been made as a treatment for these cases. This is a case report of a 9-month-old male infant with an intractable CSDH, bilateral and large, and subsequent brain atrophy caused by traumatic head injury. Excellent results were obtained by a modified reduction cranioplasty. In brief, the patient was supine-positioned with a 20-degree flexion of the head in an attempt to obtain a large operative field. Bicoronal skin incision was combined with an additional linear one on the midline (T-shaped incision). Bilateral frontoparietal craniotomy with periosteum was made to keep the midline bony bridge overlying the superior sagittal sinus (SSS). The resulting extensive dural opening allowed complete evacuation of the subdural hematoma. Thereafter, the anterior part, ca. 4cm in width, of the bony bridge was removed in order to make the remaining bone able to be manipulated and connected to the frontal bone. Prior to this stage, SSS close to the crista galli was ligated and cut with the falx to avoid postoperative kinking. The dura mater was sutured so as not to leave an excessive subdural space. The bone flaps were trimmed to complete a good-shaped reconstruction. Finally, the excessive scalp was removed because the original scalp was too large for the reconstructed skull.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8295704

    Psychological, neurophysiological and therapeutic aspects of chronic pain are reviewed in the light of recent progress achieved in the respective fields (alpha-feedback training; gate-control theory; transcutaneous electrostimulation; percutaneous stereoactic radio-frequency cordotomy). The efficacy of selective large fibre stimulation has been evaluated in 39 spinal cord injury patients suffering from chronic intractable pain of 6 to 35 months's duration. Stimulation was applied daily for 6 consecutive hours. Pain reflief was assessed by verbal and visual analogue scales and McGill's pain questionaire. After 1 week, total or almost total relief of pain was reported by 49 per cent, moderate relief by 41 per cent and no improvement by 10 per cent of the cases; at a 3-months follow-up the figures were 28 per cent, 49 per cent and 23 per cent respectively.

    Background Myofascial pain syndrome (MPS) is a regional musculoskeletal pain disorder that is caused by myofascial trigger points. The objective of this study was to determine the prevalence of MPS among chronic back pain patients, as well as to identify risk factors and the outcome of this disorder. Methods This was a prospective observational study involving 126 patients who attended the Pain Management Unit for chronic back pain between 1st January 2009 and 31st December 2009. Data examined included demographic features of patients, duration of back pain, muscle(s) involved, primary diagnosis, treatment modality and response to treatment. Results The prevalence of MPS among chronic back pain patients was 63.5% (n = 80). Secondary MPS was more common than primary MPS, making up 81.3% of the total MPS. There was an association between female gender and risk of developing MPS (χ2 = 5.38, P = 0.02, O.R. = 2.4). Occupation, body mass index and duration of back pain were not significantly associated with MPS occurrence. Repeated measures analysis showed significant changes (P < 0.001) in Visual Analogue Score (VAS) and Modified Oswestry Disability Score (MODS) with standard management during three consecutive visits at six-month intervals. Conclusions MPS prevalence among chronic back pain patients was significantly high, with female gender being a significant risk factor. With proper diagnosis and expert management, MPS has a favourable outcome. PMID:21716607

    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

  18. Opioids in chronic noncancer pain: More faces from the crowd

    Watson, C Peter N

    2012-01-01

    BACKGROUND: The use of opioids for chronic noncancer pain (CNCP) remains very controversial. There are several randomized controlled trials, mostly in neuropathic pain, reporting efficacy and safety in the short term, but more long-term data are needed. Randomized controlled trials may be limited in providing data about the patients who benefit from often high-dose opioids over the long term. The present article provides details of these patients and adds to a previous case series. METHODS: The present article contains 17 case reports of 11 CNCP conditions (followed to 2011) selected to illustrate specific issues from a survey of 84 patients with intractable CNCP treated with opioids and followed every three months for a median of 11 years. The previous published survey of this group reported outcomes of pain severity, adverse effects, pain relief, satisfaction, mood, problematic opioid use, tolerance, physical dependency, functional status, health-related quality of life (HRQL), immune status and sexual function. The outcome measures for that study included a numerical rating scale for pain, the Hospital Anxiety and Depression Scale, the Brief Pain Inventory Interference Scale, the Pain Disability Index and, for HRQL, the Short-Form Health Survey 12 version 2. Most patients in the total sample reported 50% or greater relief and a moderate improvement in disability. Scores for functional status and HRQL were not severely affected. Problematic use, tolerance and serious adverse effects, including constipation, were not major issues. These selected patient reports were chosen, not to illustrate optimal results, but rather important aspects of the diagnoses, opioids and doses, the paucity of intolerable adverse effects, particular issues (concurrent addiction history, bipolar disorder and combination therapy), disease-specific and other outcomes and duration of follow-up with complex pain problems. RESULTS: Opioids were found to be safe and useful in the long term for

    In recent years there has been an increased interest in pain neuroscience in physical therapy.1,2 Emerging pain neuroscience research has challenged prevailing models used to understand and treat pain, including the Cartesian model of pain and the pain gate.2–4 Focus has shifted to the brain's processing of a pain experience, the pain neuromatrix and more recently, cortical reorganisation of body maps.2,3,5,6 In turn, these emerging theories have catapulted new treatments, such as therapeutic neuroscience education (TNE)7–10 and graded motor imagery (GMI),11,12 to the forefront of treating people suffering from persistent spinal pain. 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. This lack of research and writings in regards to the thoracic spine is not unique to pain science, but also in manual therapy. There are, however, very unique pain neuroscience issues that skilled manual therapists may find clinically meaningful when treating a patient struggling with persistent thoracic pain. Utilising the latest understanding of pain neuroscience, three key clinical chronic thoracic issues will be discussed – hypersensitisation of intercostal nerves, posterior primary rami nerves mimicking Cloward areas and mechanical and sensitisation issues of the spinal dura in

    Five hundred consecutive patients attending a psychiatric clinic were examined in order to ascertain the prevalence of chronic pain in various psychiatric illnesses and demographic categories. Chronic pain was found to be a frequent symptom in anxiety neurosis (60%), neurotic depression (45%) and hysteria (24.3%). Less than 3% of psychotic patients reported chronic pain. Females and those patients who had entered further education beyond secondary level were found to have significantly higher (P less than 0.001) representation as compared to the psychiatric population without pain. The results are in accordance with certain earlier studies carried out almost two decades ago. Chronic pain was found to be a common symptom of psychiatric illness, reported by 18.6% patients, especially those diagnosed as having neurosis. It was also reported more often by females and by those with a higher education. The reasons for these observations require investigation.

    From the point of view of healthcare policies, improvement in pain care has been required for years; however, there is a great discrepancy between the current need for pain care and the actual provision by healthcare services. This article seeks to demonstrate that while healthcare policies are one of the critical factors involved, a variety of conceptual, diagnostic and therapeutic causes should also be taken into account. Firstly, considering that pain care is primarily concerned with the suffering of pain by patients, the focus lies with their conscious experience in order to define the patients' understanding of pain. Additionally, in this article current biomedical and psychosocial comprehension concerning chronic pain will be illustrated and why it is necessary to broaden our horizons in order to do justice to patients with chronic pain.

    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.

    Subjective disability is considered as the variable that reflects the impact of chronic pain on a patient's life. This study examines the questions of which syndrome or patient characteristics determine subjective disability and whether there are differences between samples of patients with chronic headaches and low back pain. Direct pain variables and depression, pain coping strategies, and pain-related self-statements (including catastrophizing) are introduced into multivariate regression analyses as potential predictors of disability using a sample of 151 pain patients. Disability is not predicted by pain severity in patients with headaches or back pain. Psychological variables, especially coping strategies, are far more influential. Coping explains more variance in disability in the headache sample than in the chronic law hack pain group, whereas depression is more relevant for the degree of disability in the back pain sample. In this study, we present a critical analysis of possible interpretations of our results. We point to an overlap of concepts underlying some of the variables used: this overlap also considerably invalidates conclusions drawn from a multitude of studies done in this field, including the one presented. We strongly argue for a conceptual clarification, and consequently for the revision of assessment instruments, before further empirical work in this area is done.

    Back pain is a significant medical problem and one of the most common causes of medical consultations and missed work. In acute low back pain, patients with "red flags" indicating a serious underlying spinal or extraspinal disease must be identified by medical evaluation. Most cases of acute back pain are non-specific, and education, physical activity and pain medication is recommended. In addition, yellow flags (risks of developing chronic pain) should be recognized. The management of low back pain has been addressed by the German National Disease Management Guideline (NVL) low back pain published in 2010. This guideline evaluates the evidence and effectiveness of diagnostic and therapeutic interventions with a focus on nonspecific back pain. For chronic nonspecific low back pain intervention based on nondrug and drug therapy and a multiprofessional assessment is recommended. In patients with chronic inflammatory low back pain with onset before the age of 45, rheumatic spondyloarthritis should be considered. Recently, a guideline (S3-Leitlinie) for the management of axial spondyloarthritis including ankylosing spondylitis has become available. It provides evidence of physical and drug therapy including nonsteroidal antirheumatic and Tumor necrosis factor (TNF) inhibitor therapy. PMID:25465277

    Chronic, debilitating abdominal pain is arguably the most important component of chronic pancreatitis, leading to significant morbidity and disability. Attempting to treat this pain, which is too often unsuccessful, is a frustrating experience for physician and patient. Multiple studies to improve understanding of the pathophysiology that causes pain in some patients but not in others have been performed since the most recent reviews on this topic. In addition, new treatment modalities have been developed and evaluated in this population. This review discusses new advances in neuroscience and the study of visceral pain mechanisms, as well as genetic factors that may play a role. Updates of established therapies, as well as new techniques used in addressing pain from chronic pancreatitis, are reviewed. Lastly, outcome measures, which have been highly variable in this field over the years, are addressed. PMID:17533083

    Improving the way opioids are prescribed through clinical practice guidelines can ensure patients have access to safer, more effective chronic pain treatment while reducing the number of people who misuse, abuse, or overdose from these drugs. 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.

    The purpose of this study was to examine factors affecting the severity of neurological deficits and intractable back pain in patients with insufficient bone union following osteoporotic vertebral fracture (OVF). Reports of insufficient union following OVF have recently increased. Patients with this lesion have various degrees of neurological deficits and back pain. However, the factors contributing to the severity of these are still unknown. A total of 45 patients with insufficient union following OVF were included in this study. Insufficient union was diagnosed based on the findings of vertebral cleft on plain radiography or CT, as well as fluid collection indicating high-intensity change on T2-weighted MRI. Multivariate logistic regression analysis was performed to determine the factors contributing to the severity of neurological deficits and back pain in the patients. Age, sex, level of fracture, duration after onset of symptoms, degree of local kyphosis, degree of angular instability, ratio of occupation by bony fragments, presence or absence of protrusion of flavum, and presence or absence of ossification of the anterior longitudinal ligament (OALL) in the adjacent level were used as explanatory variables, while severity of neurological deficits and back pain were response variables. On multivariate analysis, factors significantly affecting the severity of neurological deficits were angular instability of more than 15° [adjusted odds ratio (OR), 9.24 (95% confidence interval, CI 1.49–57.2); P < 0.05] and ratio of occupation by bony fragments in the spinal canal of more than 42% [adjusted OR 9.23 (95%CI 1.15–74.1); P < 0.05]. The factor significantly affecting the severity of back pain was angular instability of more than 15° [adjusted OR 14.9 (95%CI 2.11–105); P < 0.01]. On the other hand, presence of OALL in the adjacent level reduced degree of back pain [adjusted OR 0.14 (95%CI 0.03–0.76); P < 0.05]. In this study, pronounced angular

    Primary Sjögren syndrome, which involves lesions in both the brain and spinal cord, is rarely reported. Related symptoms, such as intractable pain due to central nervous system involvement, are very rare. A 73-year-old woman diagnosed with primary Sjögren syndrome manifested with subacute encephalopathy and extensive transverse myelitis. She complained of severe whole body neuropathic pain. Magnetic resonance imaging demonstrated a non-enhancing ill-defined high intensity signal involving the posterior limb of the both internal capsule and right thalamus on a T2 fluid-attenuated inversion recovery image. Additionally, multifocal intramedullary ill-defined contrast-enhancing lesion with cord swelling from the C-spine to L-spine was also visible on the T2-weighted image. Her intractable pain remarkably improved after administration of concomitant oral doses of gabapentin, venlafaxine, and carbamazepine.

    This study reports chronic pain prevalence in a randomly selected sample of the adult Australian population. Data were collected by Computer-Assisted Telephone Interview (CATI) using randomly generated telephone numbers and a two-stage stratified sample design. Chronic pain was defined as pain experienced every day for three months in the six months prior to interview. There were 17,543 completed interviews (response rate=70.8%). Chronic pain was reported by 17.1% of males and 20.0% of females. For males, prevalence peaked at 27.0% in the 65--69 year age group and for females, prevalence peaked at 31.0% in the oldest age group (80--84 years). Having chronic pain was significantly associated with older age, female gender, lower levels of completed education, and not having private health insurance; it was also strongly associated with receiving a disability benefit (adjusted OR=3.89, P<0.001) or unemployment benefit (adjusted OR=1.99, P<0.001); being unemployed for health reasons (adjusted OR=6.41, P<0.001); having poor self-rated health (adjusted OR=7.24, P<0.001); and high levels of psychological distress (adjusted OR=3.16, P<0.001). Eleven per cent of males and 13.5% of females in the survey reported some degree of interference with daily activities caused by their pain. Prevalence of interference was highest in the 55--59 year age group in both males (17.2%) and females (19.7%). Younger respondents with chronic pain were proportionately most likely to report interference due to pain, affecting 84.3% of females and 75.9% of males aged 20--24 years with chronic pain. Within the subgroup of respondents reporting chronic pain, the presence of interference with daily activities caused by pain was significantly associated with younger age; female gender; and not having private health insurance. There were strong associations between having interfering chronic pain and receiving disability benefits (adjusted OR=3.31, P<0.001) or being unemployed due to health reasons

    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

    To communicate, understand, and prescribe treatment, it is essential that some consensually validated criteria be used to describe groups of patients who share a set of relevant attributes. Several classification systems have been developed to described relatively homogeneous subgroups of chronic pain patients. These systems have been based on theoretical perspectives of chronic pain syndromes tied to physical pathology. Alternative systems based on a priori psychological categories or empirically derived classifications also have been proposed. Some of the strengths and weaknesses of deductive and inductive approaches to classification are described, and the advantages of polydiagnostic and multiaxial approaches are described as alternatives to the traditional classification. Research on an empirically derived multiaxial classification for chronic pain is described and related to chronic orofacial pain. PMID:2085195

    Chronic pain is a major health concern affecting 80 million Americans at some time in their lives with significant associated morbidity and effects on individual quality of life. Chronic pain can result from a variety of inflammatory and nerve damaging events that include cancer, infectious diseases, autoimmune-related syndromes and surgery. Current pharmacotherapies have not provided an effective long-term solution as they are limited by drug tolerance and potential abuse. These concerns have led to the development and testing of gene therapy approaches to treat chronic pain. The potential efficacy of gene therapy for pain has been reported in numerous pre-clinical studies that demonstrate pain control at the level of the spinal cord. This promise has been recently supported by a Phase-I human trial in which a replication-defective herpes simplex virus (HSV) vector was used to deliver the human pre-proenkephalin (hPPE) gene, encoding the natural opioid peptides met- and leu-enkephalin (ENK), to cancer patients with intractable pain resulting from bone metastases (Fink et al., 2011). The study showed that the therapy was well tolerated and that patients receiving the higher doses of therapeutic vector experienced a substantial reduction in their overall pain scores for up to a month post vector injection. These exciting early clinical results await further patient testing to demonstrate treatment efficacy and will likely pave the way for other gene therapies to treat chronic pain. PMID:22668775

    Mesenteric panniculitis is a chronic illness that is characterized by fibrosing inflammation of the mesenteries that can lead to intractable abdominal pain. Pain control is a crucial component of the management plan. Most patients will improve with oral corticosteroids treatment, however, some patients will require a trial of other immunosuppressive agents, and a minority of patients will continue to have refractory disease. Endoscopic ultrasound guided celiac plexus block is used frequently to control abdominal pain in patients with pancreatic pathology. To our knowledge there are no case reports describing its use in mesenteric panniculitis patients with refractory abdominal pain. PMID:25992196

    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.

    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.

    Although acute pain is a physiological response warning the human body of possible harm, chronic pain can be a pathological state associated with various diseases or a disease in itself. In the United States alone, around one-third of the population has experienced a chronic pain condition and annual cost to the society is in the range of 500-600 billion dollars.(1) It should be noted that if at all this is a very modest estimate, it surpasses the costs associated with cancer, heart disease, and diabetes combined.(1) Unfortunately, despite these humongous costs, the treatment of chronic pain is inadequate.(1) Chronic pain affects individuals in a variety of forms, and below we highlight some of the most common chronic pain conditions seen in a pain clinic. Most of these disorders are difficult to treat and typically require multimodal therapy including pharmacotherapy, behavioral modification, and targeted interventions. We have summarized the scope of each disorder, clinical features, proposed mechanisms, and current therapies for them (Table 1).

    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 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

  5. Change Pain: changing the approach to chronic pain.

    2011-08-01

    In Italy, chronic pain has a prevalence of about 26%, a rate that warrants efforts by specialists and primary care physicians to improve its treatment. From a study of various treatment systems, it is clear that a radical change in the approach to pain pathology is needed. To this end, the Change Pain International Advisory Board*, an international panel of experts, highlighted the limits to current treatment schemes and proposed new strategies. Among the criticalities are poor or inadequate communication between physician and patient, difficulty in qualitative and quantitative measurement of pain, management of adverse effects, and the "vicious circle" generated by current therapies, often the cause of poor compliance with pain treatment or discontinuation of analgesic therapy. A further limitation to current therapeutic practice is to consider pain intensity as the sole reference parameter in its treatment. In light of these considerations, the Advisory Board has drawn up a strategy to improve outcomes of pain therapy: 1) a shared therapeutic pact between physician and patient based on efficacious communication rather than on information alone; 2) identification of defined therapeutic objectives that allow for reaching a balance between reduction of pain and occurrence of adverse effects; 3) adoption of drug therapies that respond at least in part to an approach based on the pathogenic mechanism of pain rather than on pain intensity alone.

    Objective The main object of this pilot study was to investigate the safety of administering onabotulinumtoxinA (BTA) towards the sphenopalatine ganglion (SPG) in intractable chronic cluster headache. Efficacy data were also collected to provide indication on whether future placebo-controlled studies should be performed. Method In a prospective, open-label, uncontrolled study, we performed a single injection of 25 IU (n = 5) or 50 IU BTA (n = 5) towards the SPG in 10 patients with intractable chronic cluster headache with a follow-up of 24 weeks. The primary outcome was adverse events (AEs) and the main efficacy outcome was attack frequency in weeks 3 and 4 post-treatment. Results A total of 11 AEs were registered. There was one severe adverse event (SAE): posterior epistaxis. The number of cluster headache attacks (main efficacy outcome) was statistically significantly reduced in the intention-to-treat analysis from 18 ± 12 per week in baseline to 11 ± 14 (p = 0.038) in weeks 3 and 4, and five out of 10 patients had at least 50% reduction of attack frequency compared to baseline. The cluster attack frequency was significantly reduced for five out of six months post-treatment. Conclusion Randomised, placebo-controlled studies are warranted to establish the potential of this possible novel treatment of cluster headache. PMID:26232105

    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

    This paper reviews the impact of genetic variability of drug metabolizing enzymes, transporters, receptors, and pathways involved in chronic pain perception on the efficacy and safety of analgesics and other drugs used for chronic pain treatment. Several candidate genes have been identified in the literature, while there is usually only limited clinical evidence substantiating for the penetration of the testing for these candidate biomarkers into the clinical practice. Further, the pain-perception regulation and modulation are still not fully understood, and thus more complex knowledge of genetic and epigenetic background for analgesia will be needed prior to the clinical use of the candidate genetic biomarkers.

    Background Chronic pain is common, often widespread and has a substantial impact on health and quality of life. The relationship between chronic pain and mortality is unclear. This systematic review aimed to identify and evaluate evidence for a relationship between chronic pain and mortality. Methods A search of ten electronic databases including EMBASE and MEDLINE was conducted in March 2012, and updated until March 2014. Observational studies investigating the association between chronic or widespread pain (including fibromyalgia) and mortality were included. Risk of bias was assessed and a meta-analysis was undertaken to quantify heterogeneity and pool results. A narrative review was undertaken to explore similarities and differences between the included studies. Results Ten studies were included in the review. Three reported significant associations between chronic or widespread pain and mortality in unadjusted results. In adjusted analyses, four studies reported a significant association. The remaining studies reported no statistically significant association. A meta-analysis showed statistically significant heterogeneity of results from studies using comparable outcome measures (n = 7)(I2 = 78.8%) and a modest but non-significant pooled estimate (MRR1.14,95%CI 0.95–1.37) for the relationship between chronic pain and all-cause mortality. This association was stronger when analysis was restricted to studies of widespread pain (n = 5,I2 = 82.3%) MRR1.22(95%CI 0.93–1.60). The same pattern was observed with deaths from cancer and cardiovascular diseases. Heterogeneity is likely to be due to differences in study populations, follow-up time, pain phenotype, methods of analysis and use of confounding factors. Conclusion This review showed a mildly increased risk of death in people with chronic pain, particularly from cancer. However, the small number of studies and methodological differences prevented clear conclusions from being drawn

    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

    Spatial perception is sensitive to the energetic costs required to perform intended actions. For example, hills look steeper to people who are fatigued or burdened by a heavy load. Similarly, perceived distance is also influenced by the energy required to walk or throw to a target. Such experiments demonstrate that perception is a function, not just of optical information, but also of the perceiver's potential to act and the energetic costs associated with the intended action. In the current paper, we expand on the notion of "cost" by examining perceived distance in patients diagnosed with chronic pain, a multifactorial disease, which is experienced while walking. We found that chronic pain patients perceive target distances to be farther away compared with a control group. These results indicate the physical, and perhaps emotional, costs of chronic pain affect spatial perceptions.

    2015-01-01

    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

    2010-01-01

    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

    2011-01-01

    Chronic groin pain after herniorrhaphy is a concern, as approximately 10% of patients undergoing inguinal hernia repair have symptoms, which often limit physical ability. The etiopathogenesis is related to periostitis pubis (somatic pain) and more often to nerve injury (neuropathic pain). It is clinically important to distinguish between these two types of pain because treatment can be different. The physician should establish a routine diagnosis and treatment, and most patients will need surgical approach. Prevention of this condition is of great importance and can lead to a lower incidence of the syndrome. Some measures are key, such as how to avoid application of stitches or clips to the pubis periosteum, using the prosthesis carefully and identifying the nerves in the groin. This last measure is certainly the most important in the prevention of chronic pain and involves thorough knowledge of anatomy and the use of refined technique.

    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.

    Pain is the major symptom in chronic pancreatitis. Its intensity frequently necessitates partial or complete pancreatectomy. The mechanisms of pain are not yet fully understood and, thereby, the therapeutic management is still controversial. Possible causes of pain include outflow obstruction with increased ductal and parenchymal pressure within the pancreas, and inflammatory involvement of intrapancreatic nerve fibres. Possible extrapancreatic causes are common bile duct and duodenal stenosis. The first theory has recently been substantiated by the demonstration of a definite relationship between intrapancreatic pressure, as measured intraoperatively, and intensity of pain. Infiltration of inflammatory cells around the nerves together with an increase in the number of nerve fibres in the fibrotic pancreatic tissue has been proposed as a possible cause of pain in chronic pancreatitis. Moreover, immunohistological studies have shown that the amount of neurotransmitters, such as substance P, is increased in afferent pancreatic nerves. Stenosis of the common bile duct and duodenum has been reported to be associated with severe abdominal pain. Common bile duct and duodenal stenosis in chronic pancreatitis may be caused by extension of fibrosis and active inflammation of the pancreas within the wall of duodenum and bile duct. This article updates the different pathogenetic mechanisms in pancreatic pain and the current therapeutic possibilities with their advantages and shortcomings.

    Context: Chronic lower leg pain in athletes can be a frustrating problem for patients and a difficult diagnosis for clinicians. Myriad approaches have been suggested to evaluate these conditions. With the continued evolution of diagnostic studies, evidence-based guidance for a standard approach is unfortunately sparse. Evidence Acquisition: PubMed was searched from January 1980 to May 2011 to identify publications regarding chronic lower leg pain in athletes (excluding conditions related to the foot), including differential diagnosis, clinical presentation, physical examination, history, diagnostic workup, and treatment. Results: Leg pain in athletes can be caused by many conditions, with the most frequent being medial tibial stress syndrome; chronic exertional compartment syndrome, stress fracture, nerve entrapment, and popliteal artery entrapment syndrome are also considerations. Conservative management is the mainstay of care for the majority of causes of chronic lower leg pain; however, surgical intervention may be necessary. Conclusion: Chronic lower extremity pain in athletes includes a wide differential and can pose diagnostic dilemmas for clinicians. PMID:23016078

    In the modern age of advanced surgical techniques and pharmacologic management, bacterial spinal infections (SIs) can be managed (either eradicated or suppressed) in many hosts. However, the optimal management of SIs may be limited by patient comorbidities, which do not allow for surgical management, or limited by antimicrobial options due to side effects, toxicities, or emerging drug resistance. In these settings, frank and honest discussion regarding risks and benefits of treatment should be pursued, including that the SI may be a terminal illness. In this case series, we present 3 patients who had bacterial SIs whose treatments were limited by the above-mentioned factors. Furthermore, each case presented challenges regarding optimal medical management of somatic and neuropathic pain associated with the SI. PMID:22144661

    2007-09-01

    Methadone treatment in chronic pain patients is still limited owing to misconceptions about addiction, safety, and its unique pharmacokinetic and pharmacodynamic properties. Nevertheless, patients with chronic noncancer pain are frequently treated with methadone at our Pain Centre either as the first opioid of choice, for specific pain conditions, or as a second-line opioid in patients developing tolerance or intractable side effects with other opioids. The aim of this study was to examine whether a nurse case management program of chronic pain patients treated with methadone is feasible and safe in trying to improve patients' care in an ambulatory setting. This program consisted of three phases: initial primary education session, telephone follow-up during methadone titration, and a subsequent maintenance period. The nurse case manager functioned autonomously and when required reported to and consulted the physician. The study included 75 subjects and was done over a nine-month period by completing follow-up questionnaires for every call. Of a total of 194 recorded calls, 41% were unscheduled. Forty-four percent of phone calls resulted in a methadone increase and 11% led to a decrease or cessation of methadone. No patients developed serious morbidity or mortality. Fifty-seven percent of patients were either satisfied or very satisfied with their treatment. A nurse-led case management program of methadone in chronic pain patients can improve patient care in an ambulatory setting. PMID:17723930

    2016-01-01

    Analgesic medications compounded for topical use are gaining popularity for the management of chronic pain. The advantages of topical pain medications include reduction of systemic adverse effects, improved patient acceptance, few drug interactions, ease of dose determination, avoidance of first-pass metabolism, and direct access to the target site. Compounded topical medications typically use a mixture of 3 or more single medications to achieve multiple complementary effects at lower doses of each individual medication. Herein, we review the mechanisms, adverse effects, and evidence for some of the most commonly used medications in topical compounds for pain management. Because more topical medications are used for chronic pain, dermatologists can expect an increase in irritant and allergic contact dermatitis related to these medications. PMID:27649348

    The acute whiplash injury is a significant health burden for patients and the healthcare system. Traditional approaches to treatment fail to resolve this ever growing medicolegal and social problem. A new biopsychosocial model of whiplash disorder encourages new ways of treating and preventing of the chronic disability. This biopsychosocial model takes into account the mechanism by which acute pain becomes chronic pain, and how this can be prevented. Specific education and treatments encourage a behaviour after whiplash injury that is conducive to more rapid recovery, and provides the whiplash patient with insight into the mediators of chronic pain. The article describes in practical terms how to use education, reassurance, a more judicious use of therapy, and exercise to achieve this goal. Practical guidelines are provided on educating the patient about other symptoms that may cause concern. PMID:12421777

    A 79-year-old female presented with incapacitating chronic neck pain. The patient's pain which was greatest on the left side persisted for 18 months and was described as stabbing in nature (10/10 intensity). In addition to her neck pain, the patient described having frequent headaches. After six weeks of physical therapy and undergoing a rhizotomy procedure, she showed no prolonged improvement. An epidural steroid injection provided only temporary pain relief and was followed by a successful posterior fusion using the Harms technique with iliac crest autogenous bone grafting and placement of polyaxial screws in the C1 lateral masses and C2 pedicles. At the one-year follow-up the patient reported no pain or complaints. In general, C1-C2 arthrodesis is a surgical challenge due to the proximity of neurovascular structures (vertebral arteries and spinal cord) and wide range of the joint motion. The Harms technique is one of many techniques developed to reduce anatomical risk and improve results related to biomechanical stability and fusion rates. PMID:27774361

    2006-01-01

    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.

    Chronic regional pain syndrome (CRPS) can be intractable to treat and patients sometimes suffer for many years. Therefore, new treatment strategies are needed to alleviate symptoms in CRPS patients. This case report describes a patient suffering from intractable CRPS type 1 for 13 years. Due to her swollen painful feet and left knee she is wheelchair-bound. The combination of palmitoylethanolamide and ketamine 10% cream reduced her pain by more than 50% after 1 month of treatment, and a marked reduction in swelling and skin discoloration was noticed. Furthermore, she could walk independently again and she experienced no side effects. Thus, palmitoylethanolamide and topical ketamine could be a combination therapy option for treating CRPS patients.

    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

    51 patients suffering chronic pain, with different diagnoses, were treated in groups as outpatients using a cognitive behavioural approach. Groups of 7-8 patients met for two hours a week for six weeks. The groups were led by a team consisting of a clinical psychologist, a physiotherapist and a doctor. The patients learned about different aspects of pain, self-exercise and relaxation by selfhypnosis. Group dynamics was used to strengthen self-esteem, facilitate learning and encourage a change of attitude towards pain. Each patient answered a questionnaire about activities, level of pain, drugs and psychological symptoms before and immediately after treatment, and at follow-up one year later. At follow-up, 43% were less depressed, 70% felt less pain and 50% were more active and used less drugs.

    Pain is a leading symptom in chronic pancreatitis (CP) and often its management necessitates surgical intervention. Nevertheless the presence of different hypotheses, the pathophysiology of pain is not understood, thus the indications for therapy remain controversial. Increased pressure within the ductal system and/or the parenchyma has been suggested to be one of the causes of pain. This controversial theory has been substantiated by the demonstration of a relationship between intrapancreatic pressure and intensity of pain. On the other hand, recent studies have shown the inflammatory involvement of intrapancreatic nerve fibres in a so called "neuroimmune interaction". In fact, infiltration of inflammatory cells around the nerves together with an increase in the number of nerve fibres in the fibrotic pancreatic tissue have been proposed as a possible cause of pain in chronic pancreatitis. Moreover, immunohistological studies have shown that the amount of neurotransmitters, such as substance P and calcitonin gene related peptide, is increased in afferent pancreatic nerves and a close interrelationship between pain and immune cell infiltration of the nerves has been reported in CP. In addition to these hypothesis, extrapancreatic causes such as common bile duct obstruction and duodenal stenosis are discussed. This article review points to the different pathogenic mechanisms of pancreatic pain in CP.

    Dysregulation of pain neurocircuitry and neurochemistry has been increasingly recognized as playing a critical role in a diverse spectrum of diseases including migraine, fibromyalgia, depression, and PTSD. Evidence presented here supports the hypothesis that alcohol dependence is among the pathologies arising from aberrant neurobiological substrates of pain. In this review, we explore the possible influence of alcohol analgesia and hyperalgesia in promoting alcohol misuse and dependence. We examine evidence that neuroanatomical sites involved in the negative emotional states of alcohol dependence also play an important role in pain transmission and may be functionally altered under chronic pain conditions. We also consider possible genetic links between pain transmission and alcohol dependence. We propose an allostatic load model in which episodes of alcohol intoxication and withdrawal, traumatic stressors, and injury are each capable of dysregulating an overlapping set of neural substrates to engender sensory and affective pain states that are integral to alcohol dependence and comorbid conditions such as anxiety, depression, and chronic pain.

    Given the pervasive effect of chronic pain, a comprehensive approach to nursing care is needed. Addressing the physical effects of persistent pain on multiple systems and bodily functions requires combining (drug and nondrug) interventions to reduce pain and improve functioning. Targeting anxiety, depression and anger effectively can halt or even reverse the escalation of pain attributed to emotions. Recognizing belief patterns associated with distress and disability, while challenging patients to rethink the truthfulness of their perceptions is an important step in helping patients think, feel, and do better. Eliciting self-reflective narratives about the context of pain in their lives taps into the spiritual domain and initiates processes of grieving, forgiveness, and acceptance that are needed to transcend perceived limits and find new meaning in their lives. By attending to social interactions, including therapeutic relationships, chronic pain patients can become more independent and involved in family or socially meaningful activities. Combined, nurses can help patients restore joy, functioning, and a sense of purpose despite the devastating toll persistent pain has taken.

    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

    Central pain following traumatic brain injury (TBI) has not been studied in depth. Our purpose was to conduct a systematic study of patients with TBI suffering from chronic central pain, and to describe the characteristics of the central pain. Groups were TBI patients with (TBIP) and without central pain (TBINP) and healthy controls. TBI patients with other pain mechanisms were excluded from the study. Participants underwent quantitative somatosensory testing in the painful and pain-free body regions. Thresholds for warmth, cold, heat-pain, touch and graphesthesia were measured and pathologically evoked pain (allodynia, hyperpathia and wind-up pain) evaluated. Chronic pain was mapped and characterized. Chronic pain developed at a relatively late onset (6.6+/-9 months) was almost exclusively unilateral and reported as pricking, throbbing and burning. Although both TBIP and TBINP exhibited a significant reduction in thermal and tactile sensations compared to controls, thermal sensations in the painful regions of TBIP were significantly more impaired than pain-free regions in the same patients (p<0.01) and in TBINP (p<0.01). Painful regions also exhibited very high rates of allodynia, hyperpathia and exaggerated wind-up. The characteristics of the chronic pain resembled those of other central pain patients although TBIP displayed several unique features. The sensory profile indicated that damage to the pain and temperature systems is a necessary but not sufficient condition for the development of chronic central pain following TBI. Neuronal hyperexcitability may be a contributing factor to the chronic pain.

    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

    2004-01-01

    The pathophysiology of pain in chronic pancreatitis (CP) is incompletely understood. Several hypotheses have been advanced, including pancreatic and extrapancreatic causes. The existence of different hypotheses to explain the genesis of pain in CP also reflects the different therapeutic approaches to pain in these patients. Increased intraductal pressure as a result of single or multiple strictures and/or calculi is believed to be a common cause of pain in CP patients with a dilated main pancreatic duct. Other suggested causes include pancreatic fibrosis, interstitial hypertension and pancreatic ischemia. Additionally, extrapancreatic causes like duodenal and common bile duct stenosis with scarring due to pancreatic inflammation are suggested as factors causing pain in CP. The 'neurogenic inflammation' hypothesis is a fascinating theory which is supported by different studies. Immunohistological reports have shown that the amount of neurotransmitters, such as substance P and its receptor, calcitonin gene-related peptide and other neurotransmitters, are increased in afferent pancreatic nerves and a correlation between pain and immune cell infiltration of the nerves has been reported in CP. In this review we will discuss the different pain hypotheses and will present the perspective that neuroimmune interaction is an important factor for pain generation in CP.

    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

    Objective. Opioid therapy in patients with chronic noncancer pain must be preceded by evaluation of the risk of opioid misuse. The aim of this study was to evaluate the predictive validity of the Italian translation of the Pain Medication Questionnaire (PMQ) and of the Diagnosis Intractability Risk and Efficacy Score (DIRE) in chronic pain patients. Design. 75 chronic noncancer pain patients treated with opioids were enrolled and followed longitudinally. Risk of opioid misuse was evaluated through PMQ, DIRE, and the physician's clinical evaluation. Pain experience and psychological characteristics were assessed through specific self-report instruments. At follow-ups, pain intensity, aberrant drug behaviors, and presence of the prescribed opioid and of illegal substances in urine were also checked. Results. PMQ demonstrated good internal consistency (Cronbach's α = 0.77) and test-retest reliability (r = 0.86). Significant correlations were found between higher PMQ scores and the number of aberrant drug behaviors detected at 2-, 4-, and 6-month follow-ups (P < 0.01). Also the DIRE demonstrated good predictive validity. Conclusions. The results obtained with specific tools are more reliable than the clinician's evaluation alone in predicting the risk of opioid misuse; regular monitoring and psychological intervention will contribute to improving compliance and outcome of long-term opioid use.

    The objectives of this study were to investigate whether continuous intravenous ketamine during the first 72 hours after thoracotomy could reduce the incidence and intensity of chronic postthoracotomy pain (CPTP) and to define the incidence and risk factors of CPTP. Seventy-eight patients receiving thoracotomy for lung tumor (benign or malignant) were randomly divided into two groups: ketamine group (n = 31) and control groups (n = 47). Patients in the ketamine group received intravenous ketamine 1 mg/kg before incision, followed by 2 μg/kg/minute infusion for 72 hours plus sufentanil patient-controlled intravenous analgesia after thoracotomy. Patients in the control group received intravenous a 0.9% normal saline and infusion plus sufentanil patient-controlled intravenous analgesia. The solutions patients received were blinded. The numerical rating scale (NRS) pain scores and the incidence and risk factors of CPTP were recorded during the first 6 months after surgery. Compared with control group, the incidence of chronic pain in the ketamine group did not decrease at 2 months (χ(2) = 1.599, P = .206) and 6 months (χ(2) = 0.368, P = .544) after surgery. Postoperative pain scores in the ketamine group were not significantly different from those of the control group patients at 2 months (U = 677.5, P = .593) and 6 months (U = 690.5, P = .680). The incidence of CPTP was 78.2% (61/78) at 2 months and 53.8% (42/78) at 6 months after surgery. Retractor used time (OR = 5.811, P = .002), inadequate acute pain control (NRS ≥ 5) (OR = 5.425, P = .048), and chemotherapy (OR = 3.784, P = .056) were independent risk factors for chronic postthoracotomy pain. The authors conclude that continuous intravenous ketamine (2 μg/kg/min) during the first 72 hours after thoracotomy was not beneficial to prevent chronic postthoracotomy pain. The independent risk factors for chronic postthoracotomy pain were retractor used time, inadequate acute pain control, and chemotherapy.

    The test behavior of 24 chronic low back pain patients was compared with the behavior of 24 healthy control Ss., matched for age and sex, in an experimental, acute pain situation (cold pressor-test). Chronic low back pain patients showed poorer persistence behavior and reported more pain. Thus, elements of typical chronic low back pain behavior were also present in an acute pain situation. These findings are discussed within the framework of stimulus-generalization theory. In addition, the effect of different coping strategies on pain tolerance was reconfirmed. The chronic low back pain group and the control group did not cope differently.

    The empirical support for hypnosis for chronic pain management has flourished over the past two decades. Clinical trials show that hypnosis is effective for reducing chronic pain, although outcomes vary between individuals. The findings from these clinical trials also show that hypnotic treatments have a number of positive effects beyond pain control. Neurophysiological studies reveal that hypnotic analgesia has clear effects on brain and spinal-cord functioning that differ as a function of the specific hypnotic suggestions made, providing further evidence for the specific effects of hypnosis. The research results have important implications for how clinicians can help their clients experience maximum benefits from hypnosis and treatments that include hypnotic components. PMID:24547802

    Chronic nonbacterial prostatitis is an ill-defined, painful clinical condition that is characterized by various nonspecific symptoms, some of which are related to urination or the male reproductive organs. Urologists diagnose this particular condition when the symptoms are not associated with urinary bacterial growth before and after transrectal prostate massage. In this review, we describe the recommended and optional tests that can be performed in these cases. There is significant overlap between chronic nonbacterial prostatitis and other unexplained pain conditions, raising the question as to whether the prostate is the culprit. The sources and mediators of pain and the psychological aspects of this complex condition are discussed. Treatments consist of traditional antibiotics and α-blockers. Because the pain relief is often temporary, patients seek other solutions. Various therapeutics have been introduced to satisfy the expectations of patients and physicians. We discuss other pain medications, as well as intraprostatic drug injections and shockwave therapy. Importantly, however, not all of these suggestions have been widely accepted by urologists or pain clinics.

    Epidemiologic studies continue to provide evidence that fibromyalgia is part of a spectrum of chronic widespread pain. The prevalence of chronic widespread pain is several times higher than fibromyalgia as defined by the 1990 American College of Rheumatology guidelines. There is now compelling evidence of a familial clustering of fibromyalgia cases in female sufferers; whether this clustering results from nature or nature remains to be elucidated. A wide spectrum of fibromyalgia-associated symptomatology and syndromes continues to be described. During the past year the association with interstitial cystitis has been explored, and neurally mediated hypotension has been documented in both fibromyalgia and chronic fatigue syndrome. Abnormalities of the growth hormone-insulin-like growth factor-1 axis have been also documented in both fibromyalgia and chronic fatigue syndrome. The commonly reported but anecdotal association of fibromyalgia with whiplash-type neck trauma was validated in a report from Israel. However, unlike North America, 100% of Israeli patients with posttraumatic fibromyalgia returned to work. Basic research in fibromyalgia continues to pinpoint abnormal sensory processing as being integral to understanding fibromyalgia pain. Drugs such as ketamine, which block N-methyl-D-aspartate receptors (which are often upregulated in central pain states) were shown to benefit fibromyalgia pain in an experimental setting. The combination of fluoxetine and amitriptyline was reported to be more beneficial than either drug alone in patients with fibromyalgia. A high prevalence of autoantibodies to cytoskeletal and nuclear envelope proteins was found in chronic fatigue syndrome, and an increased prevalence of antipolymer antibodies was found in symptomatic silicone breast implant recipients who often have fibromyalgia.

    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

    A number of psychosocial factors have been associated with the onset, exacerbation and/or maintenance of chronic pain in adolescents. The present study was conducted to evaluate the relative importance of vulnerability, reinforcement, and modeling. We compared 222 adolescents with chronic pain and no documented physiological etiology (headache, back, limb and abdominal pain) with 148 controls and their (respectively 183 vs. 127) parents. Analyses showed that adolescents with chronic pain are more vulnerable in terms of neuroticism, negative fear of failure, and (less) experienced social acceptance. Contrary to our expectations, the chronic pain group experienced less reinforcement for their pain behavior by both parents and peers than the control group. While the number of pain models was higher in the chronic pain group, no differences were found between their parents and those of the adolescents without chronic pain in pain experience, pain parameters, and pain coping. Regression analyses on the contribution of psychosocial factors to chronic pain and its parameters sustained the positive relation between vulnerability, (less) pain reinforcement, pain models and coping with pain. Furthermore, we also found evidence that gender differences have to be taken into account.

    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

    Background: This report describes a young woman with incomplete traumatic cervical spinal cord injury and intractable pruritus involving her dorsal forearm. Method: Case report. Findings: Anatomic distribution of the pruritus corresponded to the dermatomal distribution of her level of spinal cord injury and vertebral fusion. Symptoms were attributed to the spinal cord injury and possible cervical root injury. Pruritus was refractory to all treatments, including topical lidocaine, gabapentin, transcutaneous electrical nerve stimulation, intravenous Bier block, stellate ganglion block, and acupuncture. Conclusions: Further understanding of neuropathic pruritus is needed. Diagnostic workup of intractable pruritus should include advanced imaging to detect ongoing nerve root compression. If diagnostic studies suggest radiculopathy, epidural steroid injection should be considered. Because the autonomic nervous system may be involved in complex chronic pain or pruritic syndromes, sympatholysis via such techniques as stellate ganglion block might be effective. PMID:19777867

    Tinnitus and chronic pain are sensory-perceptual disorders associated with negative affect and high impact on well-being and behavior. It is now becoming increasingly clear that higher cognitive and affective brain systems are critically involved in the pathology of both disorders. Here, we propose that the ventromedial prefrontal cortex and the nucleus accumbens are part of a central “gatekeeping” system in both sensory modalities, which evaluates the relevance and affective value of sensory stimuli and controls information flow via descending pathways. If this frontostriatal system is compromised, long-lasting disturbances are the result. Parallels in both systems are striking and mutually informative, and progress in understanding central gating mechanisms might provide a new impetus to the therapy of tinnitus and chronic pain.

    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

    Tics are characterized by involuntary, sudden, rapid, repetitive, nonrhythmic, stereotyped movements or phonic productions. Those who suffer from either motor or phonic tics, but not both, for more than 1 year are diagnosed with chronic tic disorder. Several pharmacological interventions have been proposed for the treatment of tic disorder. Dopamine D2 receptor blockers and dopamine depletors are thought to be the most effective ones clinically. However, such treatments are suboptimal in terms of effectiveness and side effects, such as body weight gain and extrapyramidal symptoms. We report on a 13-year-old girl, with chronic motor tic disorder refractory to multiple anti-tic therapies, who showed dramatic improvement and remission after taking the crude leaf extract of Clerodendrum inerme (L) Gaertn. No side effects were observed during a follow-up of more than 2 years. To the best of our knowledge, this is the first report on the anti-tic effect of Clerodendrum inerme.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition with a heterogeneous origin that responds best to multimodal therapy. The bioflavonoid quercetin has antioxidant and antiinflammatory effects that have proven useful for treating this condition. Using the clinical phenotype system UPOINT, quercetin can be helpful for those with organ-specific complaints (bladder or prostate) and pelvic floor spasm. This article discusses the current understanding of CP/CPPS and how treatment with quercetin can be used alone or as part of multimodal therapy.

    Chronic deep brain stimulation (DBS) of the periventricular gray (PVG) has been used for the treatment of chronic central pain for decades. In recent years motor cortex stimulation (MCS) has largely supplanted DBS in the surgical management of intractable neuropathic pain of central origin. However, MCS provides satisfactory pain relief in about 50-75% of cases, a range comparable to that reported for DBS (none of the reports are in placebo-controlled studies and hence the further need for caution in evaluating and comparing these results). Our experience also suggests that there is still a role for DBS in the control of central pain. Here we present a series of eight consecutive cases of intractable chronic pain of central origin treated with PVG DBS with an average follow-up of 9 months. In each case, two electrodes were implanted in the PVG and the ventroposterolateral thalamic nucleus, respectively, under guidance of corneal topography/magnetic resonance imaging image fusion. The PVG was stimulated in the frequency range of 2-100 Hz in alert patients while pain was assessed using the McGill-Melzack visual analogue scale. In addition, local field potentials (FPs) were recorded from the sensory thalamus during PVG stimulation. Maximum pain relief was obtained with 5-35 Hz stimulation while 50-100 Hz made the pain worse. This suggests that pain suppression was frequency dependent. Interestingly, we detected low frequency thalamic FPs at 0.2-0.4 Hz closely associated with the pain. During 5-35 Hz PVG stimulation the amplitude of this potential was significantly reduced and this was associated with marked pain relief. At the higher frequencies (50-100 Hz), however, there was no reduction in the FPs and no pain suppression. We have found an interesting and consistent correlation between thalamic electrical activity and chronic pain. This low frequency potential may provide an objective index for quantifying chronic pain, and may hold further clues to the mechanism of

    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.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition among men of a wide age range, with detrimental effects on quality of life. The etiology, pathogenesis, and optimal treatment of CP/CPPS remain unknown, although progress has been made in these domains in recent years. A wide variety of pharmacologic and nonpharmacologic therapies have been studied in clinical trials, but most have shown limited efficacy in symptom alleviation. CP/CPPS is increasingly viewed as a condition that involves variable degrees of neuropathic pain. Medications such as gabapentin, pregabalin, memantine, and tricyclic antidepressants are often used in other neuropathic pain conditions and, therefore, are considered potential treatments for CP/CPPS. Few studies of these agents in patients with CP/CPPS have been reported, but future clinical trials should help to determine their utility and to characterize the pathogenetic mechanisms of pain in CP/CPPS. Combining treatment trials with biomarker, genomic, and imaging studies, in addition to epidemiologic and symptom-based assessments, will maximize the ability to probe disease etiology and pathogenesis, as well as identify effective treatment.

    As the field of pain management nears the halfway point of the Congressionally declared "Decade of Pain Control and Research," the prevalence of chronic pain and disability related thereto continue to escalate. In the context of rising costs and suffering associated with persistent pain worldwide, the chronic pain research community has increasingly recognized and investigated the role of the cognitive and affective dimensions of pain. In this paper, the authors review psychologic aspects of pain, psychopathology in chronic pain syndromes, suicidality in this population, and the use of psychotropic medications for treatment in these patients. Where possible, the authors have outlined limitations of previous research in these areas, and have highlighted and described recent studies that have addressed these perceived shortcomings. The role of the psychiatrist in the treatment of patients with chronic pain is reviewed.

    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.

    Chronic back pain is a major source of disability, decreased quality of life and healthcare costs. Treating chronic back pain is difficult, with even effective therapies only being modestly effective. Helping patients avoid the transition from acute to chronic low back pain is a promising strategy for preventing suffering and reducing healthcare utilization. The biopsychosocial model provides a useful framework for understanding factors that contribute to chronicity in low back pain, and are important targets for interventions. This article reviews recent research on predictors of chronicity and treatment strategies in higher risk patients that may be helpful for preventing chronicity. PMID:24654586

    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

    Chronic pain is a pervasive and expensive public health problem affecting roughly one-third of the American population. The inability of language to accurately convey pain expressions combined with the social stigmas associated with discussing pain persuade many sufferers to remain silent about their pain. Gender politics and fear of professional repercussions further encourage silence. This article explores the need for a safe and secure place for chronic pain sufferers to talk of their pain experiences. The extent to which digital communication technology can fulfill this need is examined. This descriptive study examines the use of one online chronic pain management workshop for its ability to create an engaged community of choice. Workshop admittance was based on participants having a qualifying chronic pain condition. A thematic discourse analysis is conducted of all entries chronic pain participants posted. In addition to goal setting, participants discuss the ways in which pain affects them on a daily basis. Two themes emerge: validation and encouragement. This study suggests that chronic pain users need a discursive space to legitimate their chronic pain identity. It confirms that online websites and virtual audiences facilitate disclosure and allow for authentic communication. The benefits of computer-mediated discussion as well as its limitations are examined. PMID:23276258

    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

    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

    The use of acupuncture for pain in pediatrics is a long-standing practice in Eastern cultures. Despite growing interest in the West, there has been relatively little systematic research on acupuncture for chronic pediatric pain. In particular, there is a paucity of randomized clinical trials testing the efficacy of acupuncture for chronic pain problems in pediatric populations. This commentary briefly reviews the history of acupuncture for pain and includes a summary of extant findings regarding potential mechanisms of its analgesic effects. Key areas for future research to advance the application of acupuncture to chronic pediatric pain problems are outlined.

    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

    Based on behavioral theory, it has been hypothesized that spouse solicitous responses to the pain behaviors of chronic pain patients may contribute to the maintenance of pain behaviors and disability. Self-report data support this hypothesis, but direct observational measures have not been used to study this association. In this study, 50 chronic pain patients and their spouses were videotaped while engaging in common household activities. and patient pain behaviors and spouse solicitous behaviors were coded from the tapes. Spouse solicitous responses to non-verbal pain behaviors were significant predictors of physical disability in the more depressed patients, and were significant predictors of rate of non-verbal pain behavior in patients who reported greater pain. Spouse solicitous responses did not predict psychosocial dysfunction or total self-reported pain behaviors. The result support behavioral theory and indicate the need for further study of the association between spouse solicitousness and patient pain behaviors/disability.

    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

    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.

    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.

    Extensive training of repetitive and highly skilled movements, as it occurs in professional classical musicians, may lead to changes in tactile sensitivity and corresponding cortical reorganization of somatosensory cortices. It is also known that professional musicians frequently experience musculoskeletal pain and pain-related symptoms during their careers. The present study aimed at understanding the complex interaction between chronic pain and music training with respect to somatosensory processing. For this purpose, tactile thresholds (mechanical detection, grating orientation, two-point discrimination) and subjective ratings to thermal and pressure pain stimuli were assessed in 17 professional musicians with chronic pain, 30 pain-free musicians, 20 non-musicians with chronic pain, and 18 pain-free non-musicians. We found that pain-free musicians displayed greater touch sensitivity (i.e., lower mechanical detection thresholds), lower tactile spatial acuity (i.e., higher grating orientation thresholds) and increased pain sensitivity to pressure and heat compared to pain-free non-musicians. Moreover, we also found that musicians and non-musicians with chronic pain presented lower tactile spatial acuity and increased pain sensitivity to pressure and heat compared to pain-free non-musicians. The significant increment of pain sensitivity together with decreased spatial discrimination in pain-free musicians and the similarity of results found in chronic pain patients, suggests that the extensive training of repetitive and highly skilled movements in classical musicians could be considered as a risk factor for developing chronic pain, probably due to use-dependent plastic changes elicited in somatosensory pathways.

    Chronic pain is a significant health problem that greatly impacts the quality of life of individuals and imparts high costs to society. Despite intense research effort in understanding of the mechanism of pain, chronic pain remains a clinical problem that has few effective therapies. The advent of human brain imaging research in recent years has changed the way that chronic pain is viewed. To further extend the use of human brain imaging techniques for better therapies, the adoption of imaging technique onto the animal pain models is essential, in which underlying brain mechanisms can be systematically studied using various combination of imaging and invasive techniques. The general goal of this thesis is to addresses how brain develops and maintains chronic pain in an animal model using fMRI. We demonstrate that nucleus accumbens, the central component of mesolimbic circuitry, is essential in development of chronic pain. To advance our imaging technique, we develop an innovative methodology to carry out fMRI in awake, conscious rat. Using this cutting-edge technique, we show that allodynia is assoicated with shift brain response toward neural circuits associated nucleus accumbens and prefrontal cortex that regulate affective and cognitive component of pain. Taken together, this thesis provides a deeper understanding of how brain mediates pain. It builds on the existing body of knowledge through maximizing the depth of insight into brain imaging of chronic pain.

    There is increasing interest in the use of complimentary and alternative medicine (CAM) for the treatment of chronic pain. This review examines alternative and complimentary therapies, which can be incorporated as part of a biopsychosocial approach in the treatment of chronic pain syndromes. In the present investigation, literature from articles indexed on PubMed was evaluated including topics of alternative therapies, complimentary therapies, pain psychology, biofeedback therapy, physical exercise therapies, acupuncture, natural and herbal supplements, whole-body cryotherapy, and smartphone technologies in the treatment of chronic pain syndromes. This review highlights the key role of psychology in the treatment of chronic pain. Cognitive behavior therapy appears to be the most impactful while biofeedback therapy has also been shown to be effective for chronic pain. Exercise therapy has been shown to be effective in short-, intermediate-, and long-term pain states. When compared to that in sham controls, acupuncture has shown some benefit for neck pain immediately after the procedure and in the short term and improvement has also been demonstrated in the treatment of headaches. The role of smartphones and whole-body cryotherapy are new modalities and further studies are needed. Recent literature suggests that several alternate therapies could play a role in the treatment of chronic pain, supporting the biopsychosocial model in the treatment of pain states. PMID:27038968

  13. Opioid Pharmacotherapy for Chronic Noncancer Pain: The American Experience

    PubMed Central

    2013-01-01

    Chronic noncancer pain is a significant and growing public health challenge in the United States. Lacking effective alternative interventions for effective chronic noncancer pain management, many physicians have turned to opioid pharmacotherapy. Increased opioid prescribing brings not only gains in therapeutic benefit but also a higher incidence of adverse drug events including increased medication misuse and opioid related mortality. Currently the United States must confront the dual problems of widespread undertreated chronic noncancer pain and a prescription opioid abuse crisis. Withholding pain relieving drugs from patients in need is unjustifiable, yet drug diversion, abuse and adverse drug events have become major social as well as medical problems. At the heart of this crisis is the lack of definitive evidence about the risk to benefit ratio of opioid pharmacotherapy for chronic noncancer pain both on an individual case and on a population basis. This article describes the extent and severity of the American chronic noncancer pain problem and the history of opioid pharmacotherapy for chronic noncancer pain in the United States. It then discusses the concept of evidence based practice and reviews current evidence supporting opioid pharmacotherapy for chronic noncancer pain as well as adverse drug events related to opioid pharmacotherapy including misuse and abuse. Finally, it considers the conflict of providing pain relief versus protecting society and reviews steps that governmental agencies, industry and others are taking to contain and ultimately resolve the problems of excessive prescribing and conflicting priorities.

    Pain management is extremely important in day surgery, and it is one of the limiting factors for this type of procedures. Locoregional anesthesia is strongly recommended for day surgery; nevertheless, it could be very difficult to localize nerve position especially in obese patients. Furthermore, a complete nerve blockade could result in a delayed discharge. We present a case of analgesic ultrasound-guided block of tibial and common peroneal nerves in the popliteal fossa without any motor function involvement in an obese patient undergoing debridement of an infected lower limb ulcer; all previous attempts of surgical debridement in day surgery with topical anesthetics had failed because of discomfort due to pain. Our aim was to ensure an optimal degree of analgesia and, at the same time, to save motor function in order to make early discharge possible. We used 15 mL ropivacaine 0.375% to obtain a differential block, taking advantage of sensitive fibers selectivity of ropivacaine. Surgical debridement was performed successfully. Our peripheral blockade was able to provide significantly prolonged analgesia without motor block that guaranteed a safe and early discharge according to the Post Anesthetic Discharge Scoring System. The satisfaction expressed by the patient and her comfort during the procedure support the choice of this approach for intractable painful ulcers of lower limb.

  15. Central and peripheral pain generators in women with chronic pelvic pain: patient centered assessment and treatment.

    PubMed

    Hoffman, Donna

    2015-01-01

    Women with chronic pelvic pain (CPP) often present without obvious cause on imaging studies, laboratory values or physical exam. Dysfunctional sensory processing in the central nervous system (CNS) may explain pain of unclear origin. Central sensitization (CS), a mechanism of centrally mediated pain, describes this abnormal processing of sensory information. Women with CPP often present with several seemingly unrelated symptoms. This can be explained by co-existing chronic pain syndromes occurring in the same patient. Central sensitization occurs in all of these pain syndromes, also described as dysfunctional pain syndromes, and thus may explain why several often occur in the same patient. Six of the most common pain disorders that co-exist in CPP include endometriosis, painful bladder syndrome/interstitial cysitis, vulvodynia, myofascial pain/ pelvic floor hypertonus, irritable bowel syndrome, and primary dysmenorrhea. Central pain generators, (pain originating from CS) and peripheral pain generators, (pain from local tissue damage), can both occur in each of these six conditions. These pain generators will be described. Chronic pain, specifically dysfunctional sensory processing, is recognized as a systemic disease process like diabetes to be managed as opposed to a local problem to be "fixed" or cured. A multi-disciplinary approach to assessment and treatment with a focus on improving emotional, physical and social functioning instead of focusing strictly on pain reduction is more effective in decreasing disability. This is best achieved by determining the patient's needs and perspective through a patient-centered approach. Algorithms for such an approach to assessment and treatment are outlined.

    Context Sickle cell disease (SCD) is an inherited hematological disease marked by intense pain. Early in life the pain is episodic, but it becomes increasingly chronic in many cases. Little is known about this emergence of a chronic pain state. Objectives The goal of this study was to determine whether adult SCD patients whose pain is still largely episodic show early signs of the disturbed pain processing (hyperalgesia, increased temporal summation) and cognition (hypervigilance and catastrophizing) that are characteristic of a chronic pain state. Methods SCD patients (n=22) and healthy controls (n=52) received noxious pressure stimulation for up to three minutes, and periodically reported pain intensity and unpleasantness on 0–10 scales, allowing the rate of pain increase (temporal summation) to be determined. Pain intensity discrimination also was measured, and attitudes toward pain were assessed. Results There were no overall differences in pain ratings or temporal summation between patient and control groups. However, patients’ experimental pain ratings tended to increase with age, and those reporting a history of very painful episodes showed particularly rapid temporal summation of pain unpleasantness. Patients were significantly impaired at discriminating intensities of noxious stimulation. Patients were more hypervigilant than controls, but catastrophizing was elevated only during pain episodes. Conclusion Most SCD patients whose pain remits entirely between episodes are not in a chronic pain state, but some—those who are older and have a history of highly painful episodes—appear to be transitioning into it. These early signs of disturbed processing may aid clinicians seeking to forestall disease progression. PMID:22579409

    We explored the use of virtual reality distraction techniques for use as adjunctive therapy to treat chronic pain. Virtual environments were specifically created to provide pleasant and engaging experiences where patients navigated on their own through rich and varied simulated worlds. Real-time physiological monitoring was used as a guide to determine the effectiveness and sustainability of this intervention. Human factors studies showed that virtual navigation is a safe and effective method for use with chronic pain patients. Chronic pain patients demonstrated significant relief in subjective ratings of pain that corresponded to objective measurements in peripheral, noninvasive physiological measures.

  19. Dysfunctional stress responses in chronic pain.

    PubMed

    Woda, Alain; Picard, Pascale; Dutheil, Frédéric

    2016-09-01

    Many dysfunctional and chronic pain conditions overlap. This review describes the different modes of chronic deregulation of the adaptive response to stress which may be a common factor for these conditions. Several types of dysfunction can be identified within the hypothalamo-pituitary-adrenal axis: basal hypercortisolism, hyper-reactivity, basal hypocortisolism and hypo-reactivity. Neuroactive steroid synthesis is another component of the adaptive response to stress. Dehydroepiandrosterone (DHEA) and its sulfated form DHEA-S, and progesterone and its derivatives are synthetized in cutaneous, nervous, and adipose cells. They are neuroactive factors that act locally. They may have a role in the localization of the symptoms and their levels can vary both in the central nervous system and in the periphery. Persistent changes in neuroactive steroid levels or precursors can induce localized neurodegeneration. The autonomic nervous system is another component of the stress response. Its dysfunction in chronic stress responses can be expressed by decreased basal parasympathethic activity, increased basal sympathetic activity or sympathetic hyporeactivity to a stressful stimulus. The immune and genetic systems also participate. The helper-T cells Th1 secrete pro-inflammatory cytokines such as IL-1-β, IL-2, IL-6, IL-8, IL-12, IFN-γ, and TNF-α, whereas Th2 secrete anti-inflammatory cytokines: IL-4, IL-10, IGF-10, IL-13. Chronic deregulation of the Th1/Th2 balance can occur in favor of anti- or pro-inflammatory direction, locally or systemically. Individual vulnerability to stress can be due to environmental factors but can also be genetically influenced. Genetic polymorphisms and epigenetics are the main keys to understanding the influence of genetics on the response of individuals to constraints. PMID:27262345

    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.

    2016-06-01

    African American grandparent caregiving is increasing, and evidence shows that grandparent caregiving influences health and its management. As older adults age, their potential of experiencing chronic pain increases, and this is profound given that physiological research shows that African Americans, aside from aging, may have a predisposition for developing chronic pain. Research shows older African Americans experience significant chronic pain, but few have discussed the implications of managing chronic pain in older African Americans who have added parental responsibility. Many older African Americans receive home healthcare services and there is a unique role for home healthcare clinicians in caring for this vulnerable population. This article discusses the impact of pain on caregiving, challenges in pain management, and practice and policy implications to assist home healthcare clinicians maintain the safety and protection of both the older grandparent and grandchildren.

    2014-01-01

    Based on theoretical considerations and recent observations, we argue that continued suffering of chronic pain is critically dependent on the state of motivational and emotional mesolimbic-prefrontal circuitry of the brain. The plastic changes that occur within this circuitry in relation to nociceptive inputs dictate the transition to chronic pain, rendering the pain less somatic and more affective in nature. This theoretical construct is a strong departure from the traditional scientific view of pain, which has focused on encoding and representation of nociceptive signals. We argue that the definition of chronic pain can be recast, within the associative learning and valuation concept, as an inability to extinguish the associated memory trace, implying that supraspinal/cortical manipulations may be a more fruitful venue for adequately modulating suffering and related behavior for chronic pain. We briefly review the evidence generated to date for the proposed model and emphasize that the details of underlying mechanisms remain to be expounded.

    The combination of prescription opioid dependence and chronic pain is increasingly prevalent and hazardous to public health. Variability in pain may explain poor prescription opioid addiction treatment outcomes in persons with chronic pain. This study examined pain trajectories and pain volatility in patients with chronic pain receiving treatment for prescription opioid addiction. We conducted secondary analyses of adults with chronic pain (n = 149) who received buprenorphine/naloxone (BUP/NLX) and counseling for 12 weeks in an outpatient, multisite clinical trial. Good treatment outcome was defined as urine-verified abstinence from opioids at treatment endpoint (Week 12) and during at least 2 of the previous 3 weeks. Pain severity significantly declined over time during treatment (b = -0.36, p < .001). Patients with greater pain volatility were less likely to have a good treatment outcome (odds ratio = 0.55, p < .05), controlling for baseline pain severity and rate of change in pain over time. A 1 standard deviation increase in pain volatility was associated with a 44% reduction in the probability of endpoint abstinence. The significant reduction in subjective pain during treatment provides observational support for the analgesic effects of BUP/NLX in patients with chronic pain and opioid dependence. Patients with greater volatility in subjective pain during treatment have increased risk of returning to opioid use by the conclusion of an intensive treatment with BUP/NLX and counseling. Future research should examine underlying mechanisms of pain volatility and identify related therapeutic targets to optimize interventions for prescription opioid addiction and co-occurring chronic pain.

    Simons, Laura; Elman, Igor; Borsook, David

    2014-01-01

    Our understanding of chronic pain involves complex brain circuits that include sensory, emotional, cognitive and interoceptive processing. The feed-forward interactions between physical (e.g., trauma) and emotional pain and the consequences of altered psychological status on the expression of pain have made the evaluation and treatment of chronic pain a challenge in the clinic. By understanding the neural circuits involved in psychological processes, a mechanistic approach to the implementation of psychology-based treatments may be better understood. In this review we evaluate some of the principle processes that may be altered as a consequence of chronic pain in the context of localized and integrated neural networks. These changes are ongoing, vary in their magnitude, and their hierarchical manifestations, and may be temporally and sequentially altered by treatments, and all contribute to an overall pain phenotype. Furthermore, we link altered psychological processes to specific evidence-based treatments to put forth a model of pain neuroscience psychology. PMID:24374383

    Chronic pain can be described as a syndrome or process of decompensation not unlike any other chronic disease or illness. As such, chronic pain patients are often difficult to work with because of the pervasive personal, social, emotional, and physical impact of the syndrome on their lives and the lives of their families. The pain curve was developed to be used as an educational instrument to assist patients in understanding the disease process, confronting denial, and self-diagnosing their illness. This curve now in use at our institution describes both the progression and the recovery of the illness. The pain curve is used as an educational tool to aid patients in addressing important recovery issues such as denial and the disease process, the progression of symptoms in a chronic illness, medication and alcohol use and abuse in the management of chronic pain, the impact on and from the family and the importance of peer support.

    While chronic pain is considered by some to be a CNS disease, little is understood about underlying neurobiological mechanisms. Addiction models have heuristic value in this regard, because both pain and addictive disorders are characterized by impaired hedonic capacity, compulsive drug seeking, and high stress. In drug addiction such symptomatology has been attributed to reward deficiency, impaired inhibitory control, incentive sensitization, aberrant learning, and anti-reward allostatic neuroadaptations. Here we propose that similar neuroadaptations exist in chronic pain patients.

    Background The emergence of anger as an important predictor of chronic pain outcomes suggests that treatments that target anger may be particularly useful within the context of chronic pain. Eastern traditions prescribe compassion cultivation to treat persistent anger. Compassion cultivation has been shown to influence emotional processing and reduce negativity bias in the contexts of emotional and physical discomfort, thus suggesting it may be beneficial as a dual treatment for pain and anger. Our objective was to conduct a pilot study of a 9-week group compassion cultivation intervention in chronic pain to examine its effect on pain severity, anger, pain acceptance and pain-related interference. We also aimed to describe observer ratings provided by patients’ significant others and secondary effects of the intervention. Methods Pilot clinical trial with repeated measures design that included a within-subjects wait-list control period. Twelve chronic pain patients completed the intervention (F= 10). Data were collected from patients at enrollment, treatment baseline and post-treatment; participant significant others contributed data at the enrollment and post-treatment time points. Results In this predominantly female sample, patients had significantly reduced pain severity and anger and increased pain acceptance at post-treatment compared to treatment baseline. Significant other qualitative data corroborated patient reports for reductions in pain severity and anger. Conclusions Compassion meditation may be a useful adjunctive treatment for reducing pain severity and anger, and for increasing chronic pain acceptance. Patient reported reductions in anger were corroborated by their significant others. The significant other corroborations offer a novel contribution to the literature and highlight the observable emotional and behavioral changes in the patient participants that occurred following the compassion intervention.

    Background Neuropathic characteristics are highly involved in the development of chronic pain both physically and psychologically. However, little is known about the relationship between neuropathic characteristics and brain morphological alteration. Objectives The aim of this study is to investigate the mechanisms of chronic pain development by examining the above-mentioned relationships by voxel-based morphometry in patients with chronic pain. Methods First, we assessed neuropathic characteristics using the painDETECT Questionnaire in 12 chronic pain patients. Second, to assess the gray matter volume changes by voxel-based morphometry, we conducted magnetic resonance imaging of the brain. We applied multiregression analysis of these two assessment methods. Results There were significant positive correlations between painDETECT Questionnaire scores and the gray matter volume in the bilateral anterior cingulate cortex and right posterior cingulate cortex. Conclusions Our findings suggest that neuropathic characteristics strongly affect the brain regions related to modulation of pain in patients with chronic pain and, therefore, contribute to the severity of chronic pain.

    Chronic pain is defined as pain lasting longer than six weeks and is one of the main complaints in elderly subjects. Frailty is a pathological condition that increases an individual's vulnerability by diminishing their homeostatic reserve, and it is considered a mortality risk factor. We examined the association between chronic pain and frailty in subjects who were recruited from a check-up clinic in Mexico City. Chronic pain and frailty were evaluated in 131 subjects through validated questionnaires. Descriptive and analytical statistics were performed. Of the participants, 41.9% presented with chronic pain, and 12.2% were frail. The unadjusted OR for the presence of frailty in subjects with chronic pain was 14.3 (95%CI 3.0-67.8), and the phi coefficient showed a weak positive correlation between the variables (Φ=0.352, p<0.001). In conclusion, chronic pain is associated with a higher risk of frailty. Well-timed diagnosis and treatment of chronic pain can help prevent dependency in these individuals. PMID:26980370

    Psychological factors have an impact on subjective pain experience. The aim of this study was to explore the occurrence of alexithymia and Early Maladaptive Schemas in a sample of 271 first visit chronic pain patients of six pain clinics. The patients completed the study questionnaire consisting of the Toronto Alexithymia Scale-20, the Finnish version of the Young Schema Questionnaire short form-extended, the Beck Depression Inventory-II, and pain variables. Alexithymic patients scored higher on Early Maladaptive Schemas and had more pain intensity, pain disability and depression than nonalexithymic patients. Both alexithymia and depression correlated significantly with most Early Maladaptive Schemas. The co-occurrence of alexithymia, Early Maladaptive Schemas and depression seems to worsen the pain experience. Screening of alexithymia, depression and Early Maladaptive Schemas may help to plan psychological treatment interventions for chronic pain patients. PMID:26040835

    Ewan, Eric E.; Martin, Thomas J.

    2013-01-01

    Previously preclinical pain research has focused on simple behavioral endpoints to assess the efficacy of analgesics in acute and chronic pain models, primarily reflexive withdrawal from an applied mechanical or thermal stimulus. However recent research has been aimed at investigating other behavioral states in the presence of pain, including spontaneous, non-elicited pain. One approach is to investigate the reinforcing effects of analgesics in animals with experimental pain, which should serve as reinforcers by virtue of their ability to alleviate the relevant subjective states induced by pain. The gold standard for assessing drug reinforcement is generally accepted to be drug self-administration, and this review highlights the ability of drugs to serve as reinforcers in animals with experimental neuropathic pain, and the extent to which this behavior is altered in chronic pain states. Additionally, intracranial self-stimulation is an operant procedure that has been used extensively to study drug reinforcement mechanisms and the manner in which neuropathic pain alters the ability of drugs to serve as reinforcers in this paradigm will also be discussed. Drug self-administration and intracranial self-stimulation have promise as tools to investigate behavioral effects of analgesics in animals with chronic pain, particularly regarding the mechanisms through which these drugs motivate consumption in a chronic pain state.

    Osteoporosis (OP) is a pathological condition that manifests clinically as pain, fractures, and physical disability, resulting in the loss of independence and the need for long-term care. Chronic pain is a multidimensional experience with sensory, affective, and cognitive aspects. Age can affect each of these dimensions and the pain that is experienced. In OP, chronic pain appears to have sensory characteristics and properties of nociceptive and neuropathic pain. Its evaluation and treatment thus require a holistic approach that focuses on the specific characteristics of this population. Pain management must therefore include pharmacological approaches, physiotherapy interventions, educational measures, and, in rare cases, surgical treatment. Most rehabilitative treatments in the management of patients with OP do not evaluate pain or physical function, and there is no consensus on the effects of rehabilitation therapy on back pain or quality of life in women with OP. Pharmacological treatment of pain in patients with OP is usually insufficient. The management of chronic pain in patients with OP is complicated with regard to its diagnosis, the search for reversible secondary causes, the efficacy and duration of oral bisphosphonates, and the function of calcium and vitamin D. The aim of this review is to discuss the most appropriate solutions in the management of chronic pain in OP. PMID:27099529

    2016-01-01

    Metastatic spinal tumors are usually quite difficult to treat. In patients with metastatic spinal tumors, conventional radiotherapy fails to relieve pain in 20–30% of cases and open surgery often causes considerable trauma and complications, which delays treatment of the primary disease. Percutaneous vertebroplasty (PVP) is considered to be useful in achieving rapid pain control and preventing further vertebral collapse due to spinal metastasis. However, symptoms of intraspinal neural compression can be contraindications to PVP. To overcome this problem, we performed PVP following targeted bipolar radiofrequency decompression, and examined the effect of the combined treatment in relieving severe radicular pain related to spinal cord compression caused by malignant metastatic tumors.

    Abstract Chronic pain after joint replacement is common, affecting approximately 10% of patients after total hip replacement (THR) and 20% of patients after total knee replacement (TKR). Heightened generalized sensitivity to nociceptive input could be a risk factor for the development of this pain. The primary aim of this study was to investigate whether preoperative widespread pain sensitivity was associated with chronic pain after joint replacement. Data were analyzed from 254 patients receiving THR and 239 patients receiving TKR. Pain was assessed preoperatively and at 12 months after surgery using the Western Ontario and McMaster Universities Osteoarthritis Pain Scale. Preoperative widespread pain sensitivity was assessed through measurement of pressure pain thresholds (PPTs) at the forearm using an algometer. Statistical analysis was conducted using linear regression and linear mixed models, and adjustments were made for confounding variables. In both the THR and TKR cohort, lower PPTs (heightened widespread pain sensitivity) were significantly associated with higher preoperative pain severity. Lower PPTs were also significantly associated with higher pain severity at 12 months after surgery in the THR cohort. However, PPTs were not associated with the change in pain severity from preoperative to 12 months postoperative in either the TKR or THR cohort. These findings suggest that although preoperative widespread pressure pain sensitivity is associated with pain severity before and after joint replacement, it is not a predictor of the amount of pain relief that patients gain from joint replacement surgery, independent of preoperative pain severity.

    Previous functional magnetic resonance imaging (fMRI) studies in healthy controls (HC) and pain-free migraine patients found activations to pain-related words in brain regions known to be activated while subjects experience pain. The aim of the present study was to identify neural activations induced by pain-related words in a sample of chronic back pain (CBP) patients experiencing current chronic pain compared to HC. In particular, we were interested in how current pain influences brain activations induced by pain-related adjectives. Subjects viewed pain-related, negative, positive, and neutral words; subjects were asked to generate mental images related to these words during fMRI scanning. Brain activation was compared between CBP patients and HC in response to the different word categories and examined in relation to current pain in CBP patients. Pain-related words vs. neutral words activated a network of brain regions including cingulate cortex and insula in subjects and patients. There was stronger activation in medial and dorsolateral prefrontal cortex (DLPFC) and anterior midcingulate cortex in CPB patients than in HC. The magnitude of activation for pain-related vs. negative words showed a negative linear relationship to CBP patients’ current pain. Our findings confirm earlier observations showing that pain-related words activate brain networks similar to noxious stimulation. Importantly, CBP patients show even stronger activation of these structures while merely processing pain-related words. Current pain directly influences on this activation. PMID:27517967

  4. A neural model for chronic pain and pain relief by extracorporeal shock wave treatment.

    PubMed

    2008-12-01

    The paper develops a new theory of chronic pain and pain relief by extracorporeal shock wave treatment. Chronic pain without underlying anatomical disorder is looked at as a pathological control function of memory. Conditioned reflexes are considered to be engraved memory traces linking sensory input of afferent signals with motor response of efferent signals. This feature can be described by associative memory functions of the nervous system. Some conditioned reflexes may cause inappropriate or pathological reactions. Consequently, a circulus vitiosus of pain sensation and muscle and/or vessel contraction is generated when pain becomes chronic (pain spiral). The key feature is a dedicated engram responsible for a pathological (painful) reaction. The pain memory may be explained by the concept of a holographic memory model published by several authors. According to this model it is shown how nervous systems may generate and recall memory contents. The paper shows how extracorporeal shock wave treatment may reorganize pathologic memory traces, thus giving cause to real and permanent pain relief. In a generalized manner, the idea of associative memory functions may help in the understanding of conditioning as a learning process and explain extracorporeal shock wave application as an efficient treatment concept for chronic pain. This concept may open the door for new treatment approaches to chronic pain and several other disorders of the nervous system.

  5. Could Stress Contribute to Pain-Related Fear in Chronic Pain?

    Learning to predict pain based on internal or external cues constitutes a fundamental and highly adaptive process aimed at self-protection. Pain-related fear is an essential component of this response, which is formed by associative and instrumental learning processes. In chronic pain, pain-related fear may become maladaptive, drive avoidance behaviors and contribute to symptom chronicity. Pavlovian fear conditioning has proven fruitful to elucidate associative learning and extinction involving aversive stimuli, including pain, but studies in chronic pain remain scarce. Stress demonstrably exerts differential effects on emotional learning and memory processes, but this has not been transferred to pain-related fear. Within this perspective, we propose that stress could contribute to impaired pain-related associative learning and extinction processes and call for interdisciplinary research. Specifically, we suggest to test the hypotheses that: (1) extinction-related phenomena inducing a re-activation of maladaptive pain-related fear (e.g., reinstatement, renewal) likely occur in everyday life of chronic pain patients and may alter pain processing, impair perceptual discrimination and favor overgeneralization; (2) acute stress prior to or during acquisition of pain-related fear may facilitate the formation and/or consolidation of pain-related fear memories; (3) stress during or after extinction may impair extinction efficacy resulting in greater reinstatement or context-dependent renewal of pain-related fear; and (4) these effects could be amplified by chronic stress due to early adversity and/or psychiatric comorbidity such depression or anxiety in patients with chronic pain.

    This prospective study of acute and sub-acute low back pain (LBP) patients was conducted to assess whether attentional biases predicted chronic pain status 3 and 6 months later. The attentional biases of 100 LBP patients were assessed within 3 months of developing pain and 6 months later. Participants also completed measures associated with outcome at 3 assessment points: baseline, 3 and 6 months later. Current pain status was assessed at follow-ups. Patients were classified as those that met standard criteria for chronic pain or those who did not (i.e., the comparison group). At baseline, participants demonstrated a bias toward sensory pain words. However, biases toward sensory pain words did not differentiate those who subsequently developed chronic pain and those who did not at either follow-up. The same bias was observed 6 months later, but again it failed to distinguish between the chronic pain and comparison groups. However, subjects who developed chronic pain at both 3 (n=22) and 6 (n=21) months demonstrated biases away from affective pain words at baseline but not 6 months later, in comparison to other participants. These results remained significant in multivariate analyses. These findings are consistent with patterns observed in the previous research, and suggest that avoidance of emotionally laden pain-related stimuli (i.e., affective pain words) is associated with negative outcomes for LBP patients in the acute and sub-acute phase. This research suggests that attentional biases in relation to pain-related stimuli are important for the development of chronic pain, but are more complex than initially thought. PMID:24028848

    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. CDC Guideline for Prescribing Opioids for Chronic Pain - United States, 2016. MMWR Recomm Rep 2016;65:1-49. DOI: http://dx.doi.org/10.15585/mmwr.rr6501e1.). PMID:27178083

    Objectives To help address the unique needs of parents of children with chronic pain, a four module, parent-only, group art therapy curriculum was designed and implemented within an interdisciplinary pain rehabilitation treatment program. We evaluated perceived satisfaction and helpfulness of the group intervention. Methods Fifty-three parents of children experiencing chronic pain enrolled in a day hospital interdisciplinary pain rehabilitation program participated. The voluntary parent art therapy group was offered one time per week for one hour. Participants completed a measure of satisfaction, helpfulness, and perceived social support at the end of each group session. Results Parents enjoyed participating in the group, agreed that they would try art therapy again, and found it to be a helpful, supportive, and validating experience. Conclusions Initial results are promising that group art therapy is an appropriate and helpful means of supporting parents of children with chronic pain during interdisciplinary pain rehabilitation.

    Chronic pain substantially impacts patient function and quality of life and is a burden to society at large in terms of increased health care utilization and loss of productivity. As a result, there is an increasing recognition of chronic pain as a public health crisis. However, there remains wide variability in clinical practices related to the prevention, assessment, and treatment of chronic pain. Certain fundamental aspects of chronic pain are often neglected including the contribution of the psychological, social, and contextual factors associated with chronic pain. Also commonly overlooked is the importance of understanding the likely neurobiological mechanism(s) of the presenting pain and how they can guide treatment selection. Finally, physicians may not recognize the value of using electronic medical records to systematically capture data on pain and its impact on mood, function, and sleep. Such data can be used to monitor onset and maintenance of treatments effects at the patient level and evaluate costs at the systems level. In this review we explain how these factors play a critical role in the development of a coordinated, evidence-based treatment approach tailored to meet specific needs of the patient. We also discuss some practical approaches and techniques that can be implemented by clinicians in order to enhance the assessment and management of individuals with chronic pain in primary care settings.

    Abstract The aim of this study was to investigate the discourses used by people with chronic pain. Using qualitative interview data from five Irish people with a variety of chronic pain conditions, Foucauldian discourse analysis was undertaken to identify the discourses in operation in participants' accounts. Three discourses were identified: a moral discourse, a discourse of pain as personal tragedy, and a biomedical discourse. A moral discourse was used to construct participants as moral individuals experiencing real pain who try to accomplish activities and fulfil social roles without burdening others. The discourse of chronic pain as personal tragedy describes the multiple negative consequences of chronic pain including activity, relationship, physical, financial, and emotional consequences, and changed expectations of the future. This discourse bolsters the moral discourse through rejecting any benefits associated with chronic pain. Participants rejected a biomedical discourse by proposing their own explanatory models of pain, resisting psychosocial understandings of pain, criticizing medical professionals and healthcare services, and challenging medical expertise, professionalism, and power. These practices allow participants to reject the patient subject-position with its attendant passivity and requirements for adherence and compliance.

    BACKGROUND: The way in which individuals with chronic pain habitually approach activity engagement has been shown to impact daily functioning, with both avoidance of one’s daily activities and overactivity (activity engagement that significantly exacerbates pain) associated with more pain, higher levels of physical disability and poorer psychological functioning. OBJECTIVE: To provide insight into the development of maladaptive habitual approaches to activity engagement in chronic pain by applying an attachment theory framework. METHODS: A sample of 164 adults with chronic pain completed selfreport measures of attachment, approach to activity and pain cognitions. Mediation analyses were undertaken to examine the direct association between attachment variables and maladaptive approaches to activity, and to test for the mediating role of pain cognitions (catastrophizing and thought suppression). RESULTS: Results demonstrated that higher levels of secure attachment were associated with lower levels of activity avoidance, which was fully mediated by lower levels of pain catastrophizing; higher levels of preoccupied or fearful attachment were directly associated with higher levels overactivity; higher levels of preoccupied attachment were associated with higher levels of activity avoidance, which was partially mediated by higher levels of pain catastrophizing; and higher levels of fearful attachment were indirectly associated with higher levels of activity avoidance through higher levels of catastrophizing. CONCLUSIONS: These results provide preliminary support for the suggestion that insecure attachment may be a source of vulnerability to the development of disabling activity patterns in chronic pain.

    Systematic reviews of psychosocial assessment and effectiveness of psychotherapy for chronic pain syndromes in older patients are rare. However, it is of particular importance to consider the psychosocial aspects of elderly people with chronic pain. This narrative review describes recommended German-language assessments of the psychosocial dimensions of pain and summarizes existing studies of psychological therapy approaches for chronic pain in old age. Effective psychometric instruments are available for the assessment of cognitive function, pain-specific attitudes, depression, fear of falling, interpersonal processes and social activities, pain management, pain acceptance, disability, psychological well-being, and quality of life. Further experience with the use of these instruments with cognitively impaired or geriatric patients is required. The efficacy of age-adapted cognitive behavioral therapy and multimodal therapy for older patients has been documented. However, there is often a lack of supporting documentation about important result parameters (e.g., quality of life, functioning in everyday life, or pain acceptance). Overall, chronic pain in elderly people requires a biopsychosocial-spiritual model of pain. More attention should be given in research and daily practice to religiosity/spirituality as a possible means of coping, while mindfulness- and acceptance-based therapies should be further explored.

    AIMS The biological basis for painful temporomandibular disorder (TMD) remains unclear. An emerging literature implicates circulating inflammatory cytokines in the development of pain sensitivity and painful TMD. One newly discovered anti-inflammatory adipokine, omentin-1, has decreased expression in several inflammatory conditions including osteoarthritis. The aim of this study was to investigate the relationship between omentin-1 levels and painful TMD. METHODS Using a case-control design, chronic painful TMD cases (n=90) and TMD-free controls (n=54) were selected participants in the multisite OPPERA study (Orofacial Pain: Prospective Evaluation and Risk Assessment). Painful TMD case status was determined by examiner using established Research Diagnostic Criteria for TMD. Levels of omentin-1 were measured in stored blood plasma samples using an enzyme-linked immunosorbent assay. Binary logistic regression calculated the odds ratios (ORs) and 95% confidence limits (CLs) for the association between omentin-1 and painful TMD. Models adjusted for study site, age, sex, and body mass index (BMI). RESULTS The unadjusted association between omentin-1 and chronic painful TMD was statistically non-significant (P=.072) Following adjustment of the negative confounding bias of covariates, odds of painful decreased 36% per standard deviation increase in circulating omentin-1 (adjusted OR=0.64, 95% CL: 0.43, 0.96. P=.031). CONCLUSION Circulating levels of omentin-1 were significantly lower in painful TMD cases than controls, suggesting that painful TMD pain is mediated by inflammatory pathways. PMID:27472522

    Objective To determine the nature and scope of pain in working-aged adults with myotonic muscular dystrophy (MMD) and facioscapulohumeral muscular dystrophy (FSHD). Design Retrospective, cross-sectional survey. Setting Community-based survey. Participants Convenience sample of subjects with MMD and FSHD. Interventions Not applicable. Main Outcome Measures Overall intensity and duration of pain, pain inference, pain sites, pain treatments, and relief provided by pain treatments. Results More subjects with FSHD (82%) than with MMD (64%) reported pain. The most frequently reported pain sites for both diagnostic groups were lower back (66% MMD, 74% FSHD) and legs (60% MMD, 72% FSHD). Significant differences in pain intensity were found between the diagnostic groups in the hands, legs, knees, ankles, and feet, with patients with MMD reporting greater pain intensity at these sites than patients with FSHD. Age was related to the onset of pain (participants reporting pain were younger than those not reporting pain in the FSHD sample), but pain severity was not significantly associated with age in those reporting pain. Respondents with both diagnoses that reported mobility limitations and used assistive devices (eg, wheelchair, cane) reported more pain severity than those with mobility limitations who did not use assistive devices, who, in turn, reported more pain severity than respondents who reported no mobility limitations at all. The treatments that were reported to provide the greatest pain relief were not necessarily those that were the most frequently tried or still used. Conclusions The findings indicate that pain is a more common problem in persons with FSHD than in persons with MMD, although it is common in both populations. In addition, these pain problems are chronic, underscoring the need to identify and provide effective pain treatments for patients with these neuromuscular diseases. PMID:18226657

    Objectives Obesity is associated with functional disability in adults with chronic pain, but less is known about obesity among youth with chronic pain. The purpose of this study was to 1) identify the prevalence of overweight and obesity in children and adolescents receiving treatment for chronic pain, and 2) examine associations between Body Mass Index (BMI), pain intensity, and activity limitations in this population. Methods Data was obtained from records of 118 patients, ages 8 to 18, seen in a multidisciplinary pediatric pain clinic. Information about age, gender, pain problem, duration and severity, medical diagnoses, medications, height and weight were collected from medical records and intake questionnaires. The CDC’s pediatric BMI calculator was used to obtain percentile and category (underweight, healthy weight, overweight, obese). Children and parents completed the Child Activity Limitations Interview-21 (CALI-21), a self-report measure of activity limitations. Results A significantly higher rate of overweight and obesity was observed among youth with chronic pain compared to a normative sample. BMI percentile was predictive of concurrent limitations in vigorous activities, according to parent report. Discussion BMI percentile and weight status may contribute to activity limitations among children and adolescents with chronic pain. Weight status is an important factor to consider in the context of treatment of chronic pain and disability in children and adolescents. PMID:20664337

    : Over the past two decades, the use of opioids to manage chronic pain has increased substantially, primarily in response to the recognized functional, emotional, and financial burden associated with chronic pain. Within this same period, unintentional death related to prescription opioids has been identified as a public health crisis, owing in part to such factors as insufficient professional training and medication overprescription, misuse, and diversion. The authors discuss current best practices for prescribing opioids for chronic pain, emphasizing patient assessment and essential patient teaching points regarding safe medication use, storage, and disposal.

    Abstract Peripheral inflammation causes mechanical pain behavior and increased action potential firing. However, most studies examine inflammatory pain at acute, rather than chronic time points, despite the greater burden of chronic pain on patient populations, especially aged individuals. Furthermore, there is disagreement in the field about whether primary afferents contribute to chronic pain. Therefore, we sought to evaluate the contribution of nociceptor activity to the generation of pain behaviors during the acute and chronic phases of inflammation in both young and aged mice. We found that both young (2 months old) and aged (>18 months old) mice exhibited prominent pain behaviors during both acute (2 day) and chronic (8 week) inflammation. However, young mice exhibited greater behavioral sensitization to mechanical stimuli than their aged counterparts. Teased fiber recordings in young animals revealed a twofold mechanical sensitization in C fibers during acute inflammation, but an unexpected twofold reduction in firing during chronic inflammation. Responsiveness to capsaicin and mechanical responsiveness of A-mechanonociceptor (AM) fibers were also reduced chronically. Importantly, this lack of sensitization in afferent firing during chronic inflammation occurred even as these inflamed mice exhibited continued behavioral sensitization. Interestingly, C fibers from inflamed aged animals showed no change in mechanical firing compared with controls during either the acute or chronic inflammatory phases, despite strong behavioral sensitization to mechanical stimuli at these time points. These results reveal the following two important findings: (1) nociceptor sensitization to mechanical stimulation depends on age and the chronicity of injury; and (2) maintenance of chronic inflammatory pain does not rely on enhanced peripheral drive.

    Because of the great prevalence of chronic pain, it is not surprising that there have been a number of influential reports by the Institute of Medicine, National Institutes of Health, and the World Health Organization that have documented the medical, social and economic problems caused by it, and the need for better pain-management programs. The present article briefly reviews these reports, and then focuses on three important areas that need to be considered when addressing the continuing and growing epidemic of one of the most prevalent types of chronic pain [chronic low back pain (CLBP)]: the biopsychosocial model of chronic pain; the paradigm shift in medicine from a disease model to an illness model of CLBP; and a review of the treatment- and cost-effectiveness of interdisciplinary chronic pain management programs. This overview will serve as an important prelude to other topics related to low back pain included in this Special Issue of Healthcare. Topics covered will range from assessment and treatment approaches, to important psychosocial mediators/moderators such as coping and pain beliefs. PMID:27417800

    Pain afflflicts over 50 million people in the US, with 30.7% US adults suffering with chronic pain. Despite advances in therapies, many patients will continue to deal with ongoing symptoms that are not fully addressed by the best conventional medicine has to offer them. The patients frequently turn to therapies outside the usual purview of conventional medicine (herbs, acupuncture, meditation, etc.) called complementary and alternative medicine (CAM). Academic and governmental groups are also starting to incorporate CAM recommendations into chronic pain management strategies. Thus, for any physician who care for patients with chronic pain, having some familiarity with these therapies-including risks and benefits-will be key to helping guide patients in making evidence-based, well informed decisions about whether or not to use such therapies. On the other hand, if a CAM therapy has evidence of both safety and efficacy then not making it available to a patient who is suffering does not meet the need of the patient. We summarize the current evidence of a wide variety of CAM modalities that have potential for helping patients with chronic pain in this article. The triad of chronic pain symptoms, ready access to information on the internet, and growing patient empowerment suggest that CAM therapies will remain a consistent part of the healthcare of patients dealing with chronic pain.

On the other hand, if a CAM therapy has evidence of both safety and efficacy then not making it available to a patient who is suffering does not meet the need of the patient. We summarize the current evidence of a wide variety of CAM modalities that have potential for helping patients with chronic pain in this article. The triad of chronic pain symptoms, ready access to information on the internet, and growing patient empowerment suggest that CAM therapies will remain a consistent part of the healthcare of patients dealing with chronic pain.

  4. A New Perspective of Neuromyopathy to Explain Intractable Pancreatic Cancer Pains; Dry Needling as an Effective Adjunct to Neurolytic Blocks

    We present a new perspective of neuromyopathy in pancreatic cancer pain (PCP) referral to bodywall; proposal of new rationale to include ultrasound guided dry needling (USGDN) of body wall muscles as an effective adjunct to neurolytic coeliac plexus block (NCPB) or splanchnic nerve radiofrequency ablation (SRF) for comprehensive interventional management. Methods: PCP response to SRF in 2 patients and NCPB in 3 patients was documented on numerical rating scale (NRS) on post procedure days 3 and 15. If the residual pain was >5 NRS on day 15, USGDN of abdominal and back muscles was started on a thrice weekly basis. The response to USGDN documented on day 30 after approximately 6 sessions of DN, showed a significant pain reduction (0-2 NRS) with 50% reduction of pre-treatment opioid consumption. This was sustained at 6 months or till their demise. Convergence of visceral and somatic nerves at the dorsal horn (viscerosomatic neurons) causes referral of visceral pain to the back and abdominal muscles. This leads to formation of myofascial trigger points (MTrPs) in the muscles which sets up a parallel network of sensitized peripheral and central motor nociceptive processing (neuromyopathy). USGDN specifically addressed the MTrPs that develop as an epiphenomenon of self-perpetuating neuromyopathy while SRF/NCPB, analgesics and neuromodulators could address only visceral nociceptive afferents (pain mediated through celiac plexus) which forms a meagre 10% of the total spinal cord afferent input. Thus, we conclude that combination of neuromyopathy and viscerosomatic convergence in PCP indicate a specific role for DN as an adjunct to SRF/NCPB in our patients PMID:26962286

    Patients with chronic pain and depression are more likely to develop opioid abuse compared to patients without depression. It is not known if this association differs by pain location. We compared the strength of association between depression and opioid misuse in patients with chronic low back pain (CLBP) vs. chronic pain of other location (CPOL). Chart abstracted data was obtained from 166 patients seeking care in a family medicine clinic. Depression was measured by the PHQ-9 and opioid misuse was measured using the Current Opioid Misuse Measure. Pain severity and interference questions came from the Brief Pain Inventory. Cross-tabulations were computed to measure the association between depression and opioid misuse stratified on pain location. Exploratory logistic regression modeled the association between depression and opioid misuse after adjusting for pain location and pain severity and interference. Depression was significantly associated with opioid misuse in CPOL but not in CLBP. Regression results indicate pain interference partly accounts for the depression-opioid misuse association. These preliminary results from a small patient sample suggest depression may co-occur with opioid misuse more often in CPOL than in CLBP. Further research is needed to compare this comorbidity in specific pain diagnoses such as arthritis, fibromyalgia and CLBP. PMID:27417622

    Cognitive factors such as catastrophic thoughts regarding pain, and conversely, one's acceptance of that pain, may affect emotional functioning among persons with chronic pain conditions. The aims of the present study were to examine the effects of both catastrophizing and acceptance on affective ratings of experimentally induced ischemic pain and also self-reports of depressive symptoms. Sixty-seven individuals with chronic back pain completed self-report measures of catastrophizing, acceptance, and depressive symptoms. In addition, participants underwent an ischemic pain induction procedure and were asked to rate the induced pain. Catastrophizing showed significant effects on sensory and intensity but not affective ratings of the induced pain. Acceptance did not show any significant associations, when catastrophizing was also in the model, with any form of ratings of the induced pain. Catastrophizing, but not acceptance, was also significantly associated with self-reported depressive symptoms when these two variables were both included in a regression model. Overall, results indicate negative thought patterns such as catastrophizing appear to be more closely related to outcomes of perceived pain severity and affect in persons with chronic pain exposed to an experimental laboratory pain stimulus than does more positive patterns as reflected in measures of acceptance.

    Autism spectrum disorder is a debilitating mental illness and social issue. Autism spectrum disorder patients suffer from social isolation, cognitive deficits, compulsive behavior, and sensory deficits, including hyposensitivity to pain. However, recent studies argued that autism spectrum disorder patients show physiological pain response and, in some cases, even extremely intense pain response to harmless stimulation. Recently, Shank gene family was reported as one of the genetic risk factors of autism spectrum disorder. Thus, in this study, we used Shank2(-) (/) (-) (Shank2 knock-out, KO) mice to investigate the controversial pain sensitivity issue and found that Shank2 KO mice showed reduced tactile perception and analgesia to chronic pain.

    Current analgesics predominately modulate pain transduction and transmission in neurons and have limited success in controlling disease progression. Accumulating evidence suggests that neuroinflammation, which is characterized by infiltration of immune cells, activation of glial cells and production of inflammatory mediators in the peripheral and central nervous system, has an important role in the induction and maintenance of chronic pain. This review focuses on emerging targets such as chemokines, proteases and the Wnt pathway that promote spinal cord neuroinflammation and chronic pain. It also highlights the anti-inflammatory and pro-resolution lipid mediators that act on immune cells, glial cells and neurons to resolve neuroinflammation, synaptic plasticity and pain. Targeting excessive neuroinflammation could offer new therapeutic opportunities for chronic pain and related neurological and psychiatric disorders. PMID:24948120

    Chronic pelvic pain has rarely been discussed in the pain management literature, although it is extremely common in general gynecological practice and often refractory to traditional medical and surgical therapy. A chronic pelvic pain program was developed to offer an alternative treatment approach for women for whom standard gynecological procedures were inappropriate or unsuccessful. Sixteen subjects completed the full 6-8 week interdisciplinary program, which included both somatic and behavioral therapies. Compared to a waiting list control the results showed a dramatic decrease in reported levels of pain following treatment. Anxiety and depression also decreased and psychosocial functioning improved, including return to work, increased social activities, and improved sexual activity. The outcome suggests that the interdisciplinary pain management approach is effective for the treatment of chronic pelvic pain. PMID:2352765

    Chronic pain is a complex phenomenon that causes a significant disruption in the lives of those affected. Chronic pain is difficult to treat and challenges healthcare professionals' abilities to implement effective treatments. Therefore, chronic pain sufferers often seek complementary alternative medicine therapies such as meditation. Literature reviews have examined studies using mindfulness-based stress reduction program as an intervention for a variety of health problems. However, no reviews exist looking at a specific patient population's utilization of meditation-based programs. Therefore, the purpose of this integrative review is to examine studies that have investigated meditation as an intervention for chronic pain, identify gaps in the literature, and make recommendations for further research.

    Chronic nonmalignant pain is estimated to affect over 50 million Americans. It frequently results in significant physical, behavioral, psychological, social, and spiritual problems for patients and their families. In spite of its prevalence and consequences, chronic pain is often misunderstood and inadequately managed by healthcare professionals. Advanced practice nurses who are knowledgeable about chronic pain and the complex biopsychosocial-spiritual needs of this patient population serve an important role in recognizing these patients and intervening appropriately in their care. The purpose of this two-part article is to provide that information. Part I outlines the pathophysiology, assessment, biopsychosocial-spiritual aspects, and pharmacological treatment of chronic pain. Part II addresses a variety of nonpharmacologic and self-management interventions one can use in the primary care setting to treat these difficult health problems. PMID:10711057

    Chronic pain after surgery limits social activity, interferes with work, and causes emotional suffering. A major component of such pain is reported as resting or spontaneous pain with no apparent external stimulus. Although experimental animal models can simulate the stimulus-evoked chronic pain that occurs after surgery, there have been no studies of spontaneous chronic pain in such models. Here the conditioned place preference (CPP) paradigm was used to reveal resting pain after experimental thoracotomy. Male Sprague Dawley rats received a thoracotomy with 1-hour rib retraction, resulting in evoked tactile hypersensitivity, previously shown to last for at least 9 weeks. Intraperitoneal injections of morphine (2.5 mg/kg) or gabapentin (40 mg/kg) gave equivalent 2- to 3-hour-long relief of tactile hypersensitivity when tested 12 to 14 days postoperatively. In separate experiments, single trial CPP was conducted 1 week before thoracotomy and then 12 days (gabapentin) or 14 days (morphine) after surgery, followed the next day by 1 conditioning session with morphine or gabapentin, both versus saline. The gabapentin-conditioned but not the morphine-conditioned rats showed a significant preference for the analgesia-paired chamber, despite the equivalent effect of the 2 agents in relieving tactile allodynia. These results show that experimental thoracotomy in rats causes spontaneous pain and that some analgesics, such as morphine, that reduce evoked pain do not also relieve resting pain, suggesting that pathophysiological mechanisms differ between these 2 aspects of long-term postoperative pain. Perspective: Spontaneous pain, a hallmark of chronic postoperative pain, is demonstrated here in a rat model of experimental postthoracotomy pain, further validating the use of this model for the development of analgesics to treat such symptoms. Although stimulus-evoked pain was sensitive to systemic morphine, spontaneous pain was not, suggesting different mechanistic

    Persistent, painful cervical lymphadenopathy associated with malaise that does not respond to oral antibiotics may be cat-scratch disease. This condition is challenging to treat and may require surgical intervention. We present a case report of an immunocompetent 47-year-old African-American woman who was diagnosed with cat-scratch disease and hospitalized after multiple outpatient evaluations for progressive, painful lymphadenopathy. This case report outlines the patient's treatment in the author's urban outpatient clinic followed by an inpatient hospital stay with surgical intervention. Although the reported incidence of cat-scratch disease is higher in whites, primary care physicians should include cat-scratch disease in their differential diagnosis for African-American patients with regional lymphadenopathy, which is a hallmark of the disease. In addition, primary care physicians should be familiar with the atypical presentations of cat-scratch disease and the broad differential diagnosis for regional lymphadenopathy, including sarcoidosis, which is more common in African Americans.

    Individuals with "insecure" adult attachment styles have been shown to experience more pain than people with secure attachment, though results of previous studies have been inconsistent. We performed a cross-sectional study on a large population-based sample to investigate whether, compared to pain free individuals, subjects with chronic widespread pain were more likely to report insecure adult attachment style. Subjects in a population-based cross-sectional study completed a self-rated assessment of adult attachment style. Attachment style was categorised as secure (i.e., normal attachment style); or preoccupied, dismissing or fearful (insecure attachment styles). Subjects completed a pain questionnaire from which three groups were identified: pain free; chronic widespread pain; and other pain. Subjects rated their pain intensity and pain-related disability on an 11 point Likert scale. Subjects (2509) returned a completed questionnaire (median age 49.9 years (IQR 41.2-50.0); 59.2% female). Subjects with CWP were more likely to report a preoccupied (RRR 2.6; 95%CI 1.8-3.7), dismissing (RRR 1.9; 95%CI 1.2-3.1) or fearful attachment style (RRR 1.4; 95%CI 1.1-1.8) than those free of pain. Among CWP subjects, insecure attachment style was associated with number of pain sites (Dismissing: RRR 2.8; 95%CI 1.2-2.3, Preoccupied: RRR=1.8, 95%CI 0.98-3.5) and degree of pain-related disability (Preoccupied: RRR=2.1, 95%CI 1.0-4.1), but not pain intensity. These findings suggest that treatment strategies based on knowledge of attachment style, possibly using support and education, may alleviate distress and disability in people at risk of, or affected by, chronic widespread pain.

    According to a recent survey, about 15 % of the Japanese population suffers from moderate-severe chronic musculoskeletal pain persisting for at least 6 months. Social factors and related psychological factors (including depression) thus appear to greatly affect chronic musculoskeletal pain. This suggests the need for measures that take these factors into account. Treatment for musculoskeletal pain at present is generally based on a biomedical model that has been used for many years in this field, and modern medical imaging technologies have been a high priority to support this model and treatment strategy. Under the concept of the biomedical model, nonsteroidal antiinflammatory drugs, channel blockers and opioid analgesics are generally used as pharmacotherapy to alleviate chronic pain. However, these drugs are commonly associated with problems such as adverse effects, drug dependency and drug abuse, and they must be used with care. Surgery may also be effective in treating certain diseases, but studies have shown that many patients suffer residual chronic pain even after such treatment. Besides, exercise therapy has been found to be effective in treating many different types of chronic pain. Lately, various countries have been launching interdisciplinary pain centers that use a multidisciplinary approach to treat chronic musculoskeletal pain. Treatment in these centers is provided by a team of specialists in anesthesiology, psychiatry and orthopedics as well as the relevant paramedical professionals. The therapeutic strategy is based on a cognitive-behavioral approach, and patients are taught about methods for restoring physical function and coping with pain, mostly with drugs and exercise therapy, so that any pain present does not impair function and the patient can reintegrate into society.

    Objective To assess the effect of multidisciplinary biopsychosocial rehabilitation on clinically relevant outcomes in patients with chronic low back pain. Design Systematic literature review of randomised controlled trials. Participants A total of 1964 patients with disabling low back pain for more than three months. Main outcome measures Pain, function, employment, quality of life, and global assessments. Results Ten trials reported on a total of 12 randomised comparisons of multidisciplinary treatment and a control condition. There was strong evidence that intensive multidisciplinary biopsychosocial rehabilitation with functional restoration improves function when compared with inpatient or outpatient non-multidisciplinary treatments. There was moderate evidence that intensive multidisciplinary biopsychosocial rehabilitation with functional restoration reduces pain when compared with outpatient non-multidisciplinary rehabilitation or usual care. There was contradictory evidence regarding vocational outcomes of intensive multidisciplinary biopsychosocial intervention. Some trials reported improvements in work readiness, but others showed no significant reduction in sickness leaves. Less intensive outpatient psychophysical treatments did not improve pain, function, or vocational outcomes when compared with non-multidisciplinary outpatient therapy or usual care. Few trials reported effects on quality of life or global assessments. Conclusions The reviewed trials provide evidence that intensive multidisciplinary biopsychosocial rehabilitation with functional restoration reduces pain and improves function in patients with chronic low back pain. Less intensive interventions did not show improvements in clinically relevant outcomes.

    This investigation was conducted to test the accuracy of unassisted pain maps drawn by patients with chronic pain. Three aspects of accuracy were investigated, the accuracy of the area of pain reported, whether all existing pains were reported, and whether related symptoms were reported. Thirty-six successive new admissions to a chronic pain rehabilitation center were used as subjects. Each patient filled out the pain map prior to meeting any professional staff. During their examination the investigators completed a new pain map without seeing the patient's map. Thirty-one pairs of pain maps were compared and scored, with most maps showing several pain areas. Area of pain was accurately represented 43% of the time. Of 139 distinct pains found during examination, only 58% were reported in the pain maps. Thirtyfour percent of related symptoms were reported. It appears that unassisted pain maps are sufficiently flawed to discourage their use as an indicator of the patients symptom location J Orthop Sports Phys Ther 1987;8(8):391-396.

    Objective To offer preliminary guidance on prescribing smoked cannabis for chronic pain before the release of formal guidelines. Quality of evidence We reviewed the literature on the analgesic effectiveness of smoked cannabis and the harms of medical and recreational cannabis use. We developed recommendations on indications, contraindications, precautions, and dosing of smoked cannabis, and categorized the recommendations based on levels of evidence. Evidence is mostly level II (well conducted observational studies) and III (expert opinion). Main message Smoked cannabis might be indicated for patients with severe neuropathic pain conditions who have not responded to adequate trials of pharmaceutical cannabinoids and standard analgesics (level II evidence). Smoked cannabis is contraindicated in patients who are 25 years of age or younger (level II evidence); who have a current, past, or strong family history of psychosis (level II evidence); who have a current or past cannabis use disorder (level III evidence); who have a current substance use disorder (level III evidence); who have cardiovascular or respiratory disease (level III evidence); or who are pregnant or planning to become pregnant (level II evidence). It should be used with caution in patients who smoke tobacco (level II evidence), who are at increased risk of cardiovascular disease (level III evidence), who have anxiety or mood disorders (level II evidence), or who are taking higher doses of opioids or benzodiazepines (level III evidence). Cannabis users should be advised not to drive for at least 3 to 4 hours after smoking, for at least 6 hours after oral ingestion, and for at least 8 hours if they experience a subjective “high” (level II evidence). The maximum recommended dose is 1 inhalation 4 times per day (approximately 400 mg per day) of dried cannabis containing 9% delta-9-tetrahydrocannabinol (level III evidence). Physicians should avoid referring patients to “cannabinoid” clinics (level

    When an organ disease is ruled out as the origin of pelvic pain, the superior hypogastric plexus (SHP) injury and consequent dysfunction could be the mechanism of visceral chronic pain perpetuation. As much as a dorsal discus herniation may harm the dorsal or ventral roots, a ventral discus herniation at L4-L5 or L5-S1 may result in direct physical trauma to the SHP, maintaining chronic visceral pain mediated by sympathetic dysfunction, conceivably also afferent fibers dysfunction. We propose that similarly to nociceptive somatic dysfunction named complex regional pain syndrome, the maintained sympathetic pelvic pain secondary to straight physical damage to the SHP characterize in fact the same disease, but in nociceptive visceral tissue, named visceral complex regional pain syndrome, a concept constructed based on the International Association for the Study of Pain criteria (1994).

    2013-01-01

    This review explores the treatment of male chronic pelvic pain syndrome (CPPS) (i.e., chronic prostatitis) through the use of neuromodulation, which is the electrical stimulation of the nervous system. Neuromodulation has been used for the treatment of chronic pain for decades, and this review will examine the theory and use of neuromodulation and the various techniques available for the treatment of CPPS. Because of limited published research, much of the data presented will not be explicitly for male CPPS, but will be extrapolated from other chronic pelvic pain studies where neuromodulation has been used. Although several types of neuromodulation techniques are currently available for chronic pelvic pain conditions, none are considered standard therapies for treating CPPS. Despite the limited evidence, neuromodulation appears to provide benefits for some patients with CPPS. The improvement of urinary symptoms is more clearly defined than improvements in pain, but at least a subset of patients in most of the published studies and case series derive some benefit in the short term, and limited evidence suggests that long-term improvement of symptoms is possible. The debate about the pathophysiology of pelvic pain syndromes continues and the mechanism of action of neuromodulation on urinary and pain symptoms has yet to be defined. The fuller understanding of both will inform the evidence basis of using neuromodulation for male CPPS. PMID:23619478

    Substance use disorders (SUDs), whether active or in remission, are often encountered in patients with chronic nonmalignant pain. Clinicians are challenged when managing chronic pain while facing substance abuse issues during the course of chronic opioid therapy (COT). Further, the interrelated behavioral symptomatology of addiction and chronic pain suggests that if one disorder is untreated, effective treatment of the other in not possible. Incomplete understanding of the overlapping presentations of the two disorders, coupled with insufficient management of both conditions, leads to undertreated pain and premature discharge of SUD patients from pain treatment. In order to achieve pain relief and optimal functionality, both conditions need to be carefully managed. This paper reviews the prevalence of SUDs in chronic pain patents; the overlapping presentation of the two disorders; risk factors and stratification for addiction; identification of addiction in the chronic pain population; and suggestions for treating patients with COT, with an emphasis on relapse prevention. With appropriate assessment and treatment, COT for chronic pain patients with a history of SUD can be successful, leading to improved functionality and quality of life.

    2007-04-01

    Chronic pain plagues older adults more than any other age group; thus, practitioners must be able to approach this problem with confidence and skill. This article reviews the assessment and treatment of the most common chronic nonmalignant pain conditions that affect older adults--myofascial pain, generalized osteoarthritis, chronic low back pain (CLBP), fibromyalgia syndrome, and peripheral neuropathy. Specific topics include essential components of the physical examination; how and when to use basic and advanced imaging in older adults with CLBP; a stepped care approach to treating older adults with generalized osteoarthritis and CLBP, including noninvasive and invasive management techniques; how to diagnose and treat myofascial pain; strategies to identify the older adult with fibromyalgia syndrome and avoid unnecessary "diagnostic" testing; pharmacological treatment for the older adult with peripheral neuropathy; identification and treatment of other factors such as dementia and depression that may significantly influence response to pain treatment; and when to refer the patient to a pain specialist. While common, chronic pain is not a normal part of aging, and it should be treated with an emphasis on improved physical function and quality of life.

  14. DNA methylation of SPARC and chronic low back pain

    PubMed Central

    2011-01-01

    Background The extracellular matrix protein SPARC (Secreted Protein, Acidic, Rich in Cysteine) has been linked to degeneration of the intervertebral discs and chronic low back pain (LBP). In humans, SPARC protein expression is decreased as a function of age and disc degeneration. In mice, inactivation of the SPARC gene results in the development of accelerated age-dependent disc degeneration concurrent with age-dependent behavioral signs of chronic LBP. DNA methylation is the covalent modification of DNA by addition of methyl moieties to cytosines in DNA. DNA methylation plays an important role in programming of gene expression, including in the dynamic regulation of changes in gene expression in response to aging and environmental signals. We tested the hypothesis that DNA methylation down-regulates SPARC expression in chronic LBP in pre-clinical models and in patients with chronic LBP. Results Our data shows that aging mice develop anatomical and behavioral signs of disc degeneration and back pain, decreased SPARC expression and increased methylation of the SPARC promoter. In parallel, we show that human subjects with back pain exhibit signs of disc degeneration and increased methylation of the SPARC promoter. Methylation of either the human or mouse SPARC promoter silences its activity in transient transfection assays. Conclusions This study provides the first evidence that DNA methylation of a single gene plays a role in chronic pain in humans and animal models. This has important implications for understanding the mechanisms involved in chronic pain and for pain therapy. PMID:21867537

    The Pain and Interoception Imaging Network (PAIN) repository (painrepository.org) is a newly created NIH (NIDA/NCCAM) funded neuroimaging data repository that aims to accelerate scientific discovery regarding brain mechanisms in pain and to provide more rapid benefits to pain patients through the harmonization of efforts and data sharing. The PAIN Repository consists of two components, an Archived Repository and a Standardized Repository. Similar to other 'open' imaging repositories, neuroimaging researchers can deposit any dataset of chronic pain patients and healthy controls into the Archived Repository. Scans in the Archived Repository can be very diverse in terms of scanning procedures and clinical metadata, complicating the merging of datasets for analyses. The Standardized Repository overcomes these limitations through the use of standardized scanning protocols along with a standardized set of clinical metadata, allowing an unprecedented ability to perform pooled analyses. The Archived Repository currently includes 741 scans and is rapidly growing. The Standardized Repository currently includes 433 scans. Pain conditions currently represented in the PAIN repository include: irritable bowel syndrome, vulvodynia, migraine, chronic back pain, and inflammatory bowel disease. Both the PAIN Archived and Standardized Repositories promise to be important resources in the field of chronic pain research. The enhanced ability of the Standardized Repository to combine imaging, clinical and other biological datasets from multiple sites in particular make it a unique resource for significant scientific discoveries.

    Objectives In group interviews, we examined strategies used to manage chronic pain from the perspective of the individual. Methods Sixteen low income overweight Latino adults participated in two group interviews facilitated by a trained moderator who inquired about the type of chronic pain suffered by participants, followed by more specific questions about pain management. Interviews were audio-recorded, transcribed verbatim (Spanish), back-translated into English, and analyzed using thematic analysis. Results Participants’ pain varied in type, location, and intensity. Participants discussed pain-related changes in activities and social life, and difficulties with health care providers, and as a result, we discovered five major themes: Pain-related Life Alterations, Enduring the Pain, Trying Different Strategies, Emotional Suffering, and Encounters with Health Care System/Providers. Discussion Findings indicated that there are opportunities for providers to improve care for low income overweight Latinos with chronic pain by listening respectfully to how pain alters their daily lives and assisting them in feasible self management strategies.

  17. From acute musculoskeletal pain to chronic widespread pain and fibromyalgia: application of pain neurophysiology in manual therapy practice.

    2009-02-01

    During the past decade, scientific research has provided new insight into the development from an acute, localised musculoskeletal disorder towards chronic widespread pain/fibromyalgia (FM). Chronic widespread pain/FM is characterised by sensitisation of central pain pathways. An in-depth review of basic and clinical research was performed to design a theoretical framework for manual therapy in these patients. It is explained that manual therapy might be able to influence the process of chronicity in three different ways. (I) In order to prevent chronicity in (sub)acute musculoskeletal disorders, it seems crucial to limit the time course of afferent stimulation of peripheral nociceptors. (II) In the case of chronic widespread pain and established sensitisation of central pain pathways, relatively minor injuries/trauma at any locations are likely to sustain the process of central sensitisation and should be treated appropriately with manual therapy accounting for the decreased sensory threshold. Inappropriate pain beliefs should be addressed and exercise interventions should account for the process of central sensitisation. (III) However, manual therapists ignoring the processes involved in the development and maintenance of chronic widespread pain/FM may cause more harm then benefit to the patient by triggering or sustaining central sensitisation.

  18. Cerebral Cortical Thickness in Chronic Pain Due to Knee Osteoarthritis: The Effect of Pain Duration and Pain Sensitization

    PubMed Central

    2016-01-01

    Objective This study investigates associations between cortical thickness and pain duration, and central sensitization as markers of pain progression in painful knee osteoarthritis. Methods Whole brain cortical thickness and pressure pain thresholds were assessed in 70 participants; 40 patients with chronic painful knee osteoarthritis (age = 66.1± 8.5 years, 21 females, mean duration of pain = 8.5 years), and 30 healthy controls (age = 62.7± 7.4, 17 females). Results Cortical thickness negatively correlated with pain duration mainly in fronto-temporal areas outside of classical pain processing areas (p<0.05, age-controlled, FDR corrected). Pain sensitivity was unrelated to cortical thickness. Patients showed lower cortical thickness in the right anterior insula (p<0.001, uncorrected) with no changes surviving multiple test correction. Conclusion With increasing number of years of suffering from chronic arthritis pain we found increasing cortical thinning in extended cerebral cortical regions beyond recognised pain-processing areas. While the mechanisms of cortical thinning remain to be elucidated, we show that pain progression indexed by central sensitization does not play a major role. PMID:27658292

    In select cases, interventional pain management techniques can bean effective adjunct to the multidisciplinary care of pediatric patients with chronic pain. The secret to success stems in proper patient selection and in delineating clear goals and expectations—motivated patients do well. Comfort measures ranging from distraction through general anesthesia should be employed to alleviate anxiety and distress, and to provide optimal working conditions for the proceduralist. In the appropriate context, the occasion to provide interventional care can be a rewarding role for the anesthesiologist to play in chronic pediatric pain patient care. PMID:23047451

    2013-01-01

    BACKGROUND: Locus of control (LOC) is related to the impact of headaches and chronic pain; however, literature evidence regarding LOC is not always consistent. Several authors consider this to be due, in part, to the separate interpretation of LOC factors, during which the interaction among them is ignored. In 1982, Wallston and Wallston proposed eight possible LOC health patterns depending on whether the individual scored high or low in each of three dimensions. OBJECTIVE: To identify these LOC patterns in patients with headaches and chronic pain, and to validate them in terms of their association with a selection of the main pain indicators. METHODS: A total of 228 individuals were recruited at three public centres in Seville, Spain. Participants completed a semistructured clinical interview and several questionnaires assessing psychological variables related to pain. The main statistical analyses used were two-step cluster analysis and ANCOVA. RESULTS: The six-cluster solution was optimal. The patterns observed coincided with: the believer in control; the yea-sayer; the pure chance; the pure internal; the pure professional; and the nay-sayer clusters. The double external or type VI clusters were not observed. Clusters could be classified from the best to the worst adjustment to chronic pain. CONCLUSIONS: These results support the empirical validity of the theoretical model of LOC patterns proposed in 1982 by Wallston and Wallston among a chronic pain population. The analysis of patterns provides more accurate information regarding the adjustment to pain compared with analysis of the LOC factors separately. PMID:23936894

    2014-01-01

    Objective Although chronic pain is a known risk factor for suicide, few studies to date have tested specific predictions about suicidal ideation that are derived from theory. The interpersonal theory of suicide proposes that the psychological constructs of thwarted belongingness and perceived burdensomeness are unique and independent precursors to suicidal ideation. We tested this hypothesis in a clinical sample of patients with chronic pain. Methods A total of 303 patients of a chronic pain rehabilitation program completed measures of pain severity, duration, and disability, cognitive-affective measures of depression and catastrophizing, and interpersonal measures of relationship distress and self-perceived burden to others. The latter measures were included as indices of the belongingness and burdensomeness constructs. Participants also rated two items pertaining to suicidal ideation. Results In a multiple regression analysis, both distress in interpersonal relations (β = 0.12, p = .037) and self-perceived burden to others (β = 0.25, p < .001) were significant predictors of suicidal ideation, even after adjusting statistically for demographic characteristics, pain severity and duration, functional limitations, catastrophizing, and depression. Conclusions These findings suggest that the interpersonal theory is relevant to understanding elevated rates of suicidal ideation among people with chronic pain and may have broader applicability to other populations with chronic illness or disability.

  3. Treating Chronic Pain with SSRIs: What Do We Know?

    2016-01-01

    Serotonin is a monoamine neurotransmitter that plays a major role in both nociception and mood regulation. Alterations in the 5-hydroxytryptophan (5HT) system have been reported in chronic pain patients. In recent years, Selective Serotonin Reuptake Inhibitors (SSRIs) have been suggested as an alternative treatment for chronic pain due to the fact that they are better tolerated presenting less secondary effects than other antidepressants such as tricyclic antidepressants. Although several clinical trials have been published, the effectiveness of SSRI as treatment for pain conditions is inconclusive. This review aims to summarise what is known, regarding the effectiveness of SSRI as a treatment for chronic pain conditions in adults. A total of 36 studies involving a total of 1898 participants were included in this review. Of the 36 trials included in the review, 2 used zimelidine as treatment, 3 used escitalopram, 4 used fluvoxamine, 4 used sertraline, 6 used citalopram, 8 used paroxetine, 9 used fluoxetine, and one used both citalopram and paroxetine. Because the trials included in this review are quite heterogeneous, only qualitative analyses were performed. SSRI seems to have an effect on most of chronic pain conditions; however, further clinical trials with good methodology leading to low risk of bias are needed in order to conclude once and for all the effect of this drug class as treatment for chronic pain conditions.

    Individuals with chronic widespread pain, including those with fibromyalgia, pose a particular challenge to treatment, given the modest effectiveness of pharmacological agents for this condition. The growing consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. Several non-pharmacological interventions, particularly exercise and cognitive-behavioural therapy (CBT), have garnered good evidence of effectiveness as stand-alone, adjunctive treatments for patients with chronic pain. In this article, evidenced-based, non-pharmacological management techniques for chronic widespread pain are described by using two broad categories, exercise and CBT. The evidence for decreasing pain, improving functioning and changing secondary symptoms is highlighted. Lastly, the methods by which exercise and CBT can be combined for a multi-component approach, which is consistent with the current evidence-based guidelines of several American and European medical societies, are addressed.

    2003-09-01

    This study explored family relationships and intimacy of women experiencing chronic pain from the perspective of the women and their family members. A narrative ethnographic qualitative research design was used. Narrative and field data were analyzed using the coding procedure outlined by Strauss aided by the QSR NUD*IST 4 qualitative computer software program. Twenty-five women self-identified as experiencing chronic pain, and 13 family members including 7 husbands, 1 father, 1 stepmother, and 4 children living in the home were interviewed. Three patterns of behavior emerged regarding family relationships: cycle of close involvement compensated with isolation, focus directed toward others, and loss of physical sexual intimacy. Findings of this study indicate that family members' perception is that chronic pain affects important basic relationships and both emotional and physical intimacy. A need exists to relieve some of the suffering that accompanies pain in these women and their families. Based on the study's findings, several treatment strategies are recommended.

    Hypersensitivity of pain pathways is considered a relevant determinant of symptoms in chronic pain patients, but data on its prevalence are very limited. To our knowledge, no data on the prevalence of spinal nociceptive hypersensitivity are available. We studied the prevalence of pain hypersensitivity and spinal nociceptive hypersensitivity in 961 consecutive patients with various chronic pain conditions. Pain threshold and nociceptive withdrawal reflex threshold to electrical stimulation were used to assess pain hypersensitivity and spinal nociceptive hypersensitivity, respectively. Using 10th percentile cutoff of previously determined reference values, the prevalence of pain hypersensitivity and spinal nociceptive hypersensitivity (95% confidence interval) was 71.2 (68.3-74.0) and 80.0 (77.0-82.6), respectively. As a secondary aim, we analyzed demographic, psychosocial, and clinical characteristics as factors potentially associated with pain hypersensitivity and spinal nociceptive hypersensitivity using logistic regression models. Both hypersensitivity parameters were unaffected by most factors analyzed. Depression, catastrophizing, pain-related sleep interference, and average pain intensity were significantly associated with hypersensitivity. However, none of them was significant for both unadjusted and adjusted analyses. Furthermore, the odds ratios were very low, indicating modest quantitative impact. To our knowledge, this is the largest prevalence study on central hypersensitivity and the first one on the prevalence of spinal nociceptive hypersensitivity in chronic pain patients. The results revealed an impressively high prevalence, supporting a high clinical relevance of this phenomenon. Electrical pain thresholds and nociceptive withdrawal reflex explore aspects of pain processing that are mostly independent of sociodemographic, psychological, and clinical pain-related characteristics.

    The February-March 2014 special issue of the American Psychologist featured articles summarizing select contributions from the field of psychology to the assessment and treatment of chronic pain. The articles examined a range of psychosocial and family factors that influence individual adjustment and contribute to disparities in pain care. The reviews also considered the psychological correlates and neurophysiological mechanisms of specific pain treatments, including cognitive-behavioral therapy, hypnosis, acceptance and commitment therapy, mindfulness, and meditation. Although a number of articles emphasized the role that negative states of mind play in pain outcomes, positive emotions were given only brief mention. Here, we provide a rationale for the inclusion of positive emotions in chronic pain research. PMID:25844656

    2011-01-01

    Chronic pain is the leading cause of disability in the United States. The transition from acute to persistent pain is thought to arise from maladaptive neuroplastic mechanisms involving three intertwined processes, peripheral sensitization, central sensitization, and descending modulation. Strategies aimed at preventing persistent pain may target such processes. Models for studying preventive strategies include persistent post-surgical pain (PPP), persistent post-trauma pain (PTP) and post-herpetic neuralgia (PHN). Such entities allow a more defined acute onset of tissue injury after which study of the long-term effects is more easily examined. In this review, we examine the pathophysiology, epidemiology, risk factors, and treatment strategies for the prevention of chronic pain using these models. Both pharmacological and interventional approaches are described, as well as a discussion of preventive strategies on the horizon. PMID:22102847

    Abdominal aortic aneurysm has a population prevalence of 2-5% and mortality in case of rupture of 80%. Up to 91% of cases is accompanied with low back pain, so it is important to include aortic aneurysm in the differential diagnosis of chronic low back pain. Low back pain is one of the most frequent reasons for consultions in Services Emergency Hospital Emergency and Primary Care Services, with an estimated 80% of population having spinal pain at some point in their lives, with 90% of them having a benign course.

  10. Chronic intraoral pain--assessment of diagnostic methods and prognosis.

    PubMed

    Pigg, Maria

    2011-01-01

    The overall goal of this thesis was to broaden our knowledge of chronic intraoral pain. The research questions were: What methods can be used to differentiate inflammatory, odontogenic tooth pain from pain that presents as toothache but is non-odontogenic in origin? What is the prognosis of chronic tooth pain of non-odontogenic origin, and which factors affect the prognosis? Atypical odontalgia (AO) is a relatively rare but severe and chronic pain condition affecting the dentoalveolar region. Recent research indicates that the origin is peripheral nerve damage: neuropathic pain. The condition presents as tooth pain and is challenging to dentists because it is difficult to distinguish from ordinary toothache due to inflammation or infection. AO is of interest to the pain community because it shares many characteristics with other chronic pain conditions, and pain perpetuation mechanisms are likely to be similar. An AO diagnosis is made after a comprehensive examination and assessment of patients' self-reported characteristics: the pain history. Traditional dental diagnostic methods do not appear to suffice, since many patients report repeated care-seeking and numerous treatment efforts with little or no pain relief. Developing methods that are useful in the clinical setting is a prerequisite for a correct diagnosis and adequate treatment decisions. Quantitative sensory testing (QST) is used to assess sensory function on skin when nerve damage or disease is suspected. A variety of stimuli has been used to examine the perception of, for example, touch, temperature (painful and non-painful), vibration, pinprick pain, and pressure pain. To detect sensory abnormalities and nerve damage in the oral cavity, the same methods may be possible to use. Study I examined properties of thermal thresholds in and around the mouth in 30 pain-free subjects: the influence of measurement location and stimulation area size on threshold levels, and time variability of thresholds

    To better understand the use of narcotic analgesics, the hydromorphone concentration was measured in serum samples from 43 patients with chronic severe pain who were receiving this drug. At the time of blood sampling, pain intensity, mood, and cognitive performance were assessed. There was large individual variation in the dose-drug level relationship. Seven patients with bone or soft tissue pain and drug levels of greater than or equal to 4 ng/ml had good pain control, whereas 10 did not. None of 15 patients with levels less than 4 ng/ml had pain control, despite drug doses similar to those given patients with higher levels. Thus 60% of the patients without control of their pain had hydromorphone levels below the lowest level that produced pain control. No patient with pain from nerve infiltration or compression had good pain control, irrespective of the drug level or dose. Poor mood correlated with high pain intensity and low drug level. Impaired cognitive performance was not related to drug level. Knowing that there is a low concentration of narcotic in the blood of a patient with chronic severe pain who is receiving high drug doses and who shows lack of both efficacy and side effects may reassure health care professionals that further narcotic dosage escalation is appropriate.

  12. THE ROLE OF SODIUM CHANNELS IN CHRONIC PAIN

    Levinson, Simon R.; Luo, Songjiang; Henry, Michael A.

    2012-01-01

    Here we review recent research into the mechanisms of chronic pain that has focused on neuronal sodium channels, a target of classic analgesic agents. We first discuss evidence that specific sodium channel isoforms are essential for the detection and conduction of normal acutely painful stimuli from nociceptors. We then review findings that show changes in sodium channel expression and localization in chronic inflammation and nerve injury in animal and human tissues. We conclude by discussing the role that myelination plays in organizing and maintaining sodium channel clusters at nodes of Ranvier in normal development and how inflammatory processes or nerve injury alter the characteristics of such clusters. Based on these findings, we suggest that chronic pain may in part result from partial demyelination of axons during chronic injury, which creates aberrant sodium channel clusters that serve as sites of ectopic sensitivity or spontaneous activity.

    Spinal cord stimulation (SCS) suppresses visceral response to colon distension in an animal model. In humans, it may be an effective therapy for chronic pain of pelvic origin, irritable bowel syndrome, and persistent unspecified abdominal pain. Described here is the case of SCS for 38-year-old woman with visceral pain secondary to chronic pancreatitis. Previous therapies included numerous endoscopic retrograde cholangiopancreatographies, multiple pancreatic duct stenting, chemical and surgical sympathectomies with short-lasting pain relief. After the initial evaluation, the patient underwent retrograde epidural differential block to determine possible source of pain. Delay in pain recurrence after block suggested that the origin of her pain was visceral. After the psychologic evaluation, the patient underwent SCS trial over 14 days. She had 2 trial leads placed epidurally via T9-T10 paramedian entry with the tips of both leads positioned at T6 vertebral body. During the trial, visual analog scale pain score decreased from 8 to 1 cm, Pain Disability Index from 62 to 14, and opioid use from 150 to 0 mg of morphine sulfate equivalent a day. After the completion of successful SCS trial, she was implanted with dual octrode leads and rechargeable pulse generator. Median pain scores decreased from 8 to 1 at 3 months after the implant. Pain Disability Index changed from 62 to 15. Opiate use decreased to none. It seems that SCS may have a significant therapeutic potential for the treatment of visceral pain secondary to chronic pancreatitis. PMID:18496389

    Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that refer pain to adjacent sites. Effective treatments are available to reduce MFPP, including myofascial trigger point release, biofeedback, and electrical stimulation. An interdisciplinary team is essential for identifying and successfully treating MFPP.

    This study used Q-methodology to explore justice-related accounts of chronic pain. Eighty participants completed the Q-sorting procedure (33 chronic pain sufferers and 47 non-pain sufferers). Analysis revealed five main factors. Three factors blame: society for poor medical and interpersonal treatment; the chronic pain sufferer for indulging in self-pity and unempathic healthcare workers for ignoring patients. A fourth factor acknowledges the unfairness of pain and encourages self-reliance. The fifth factor rejects injustice in the chronic pain discourse. Overall, there is a shared view that chronic pain brings unfair treatment, disrespect and a de-legitimization of pain. Future research ideas are suggested.

    Pain neuroscience education (PNE) is increasingly used as part of a physical therapy treatment in patients with chronic pain. A thorough clinical biopsychosocial assessment is recommended prior to PNE to allow proper explanation of the neurophysiology of pain and the biopsychosocial interactions in an interactive and patient-centered manner. However, without clear guidelines, clinicians are left wondering how a biopsychosocial assessment should be administered. Therefore, we provided a practical guide, based on scientific research and clinical experience, for the biopsychosocial assessment of patients with chronic pain in physiotherapy practice. The purpose of this article is to describe the use of the Pain - Somatic factors - Cognitive factors - Emotional factors - Behavioral factors - Social factors - Motivation - model (PSCEBSM-model) during the intake, as well as a pain analysis sheet. This model attempts to clearly establish what the dominant pain mechanism is (predominant nociceptive, neuropathic, or non-neuropathic central sensitization pain), as well as to assess the provoking and perpetuating biopsychosocial factors in patients with chronic pain. Using this approach allows the clinician to specifically classify patients and tailor the plan of care, including PNE, to individual patients. PMID:27351769

    2015-01-01

    Abstract Overactivity is a frequently used term in chronic pain literature. It refers to the phenomenon whereby individuals engage in activity in a way that significantly exacerbates pain, resulting in periods of incapacity. Overactivity, as a construct, has been derived solely from patients' self-reports, raising concerns about the legitimacy of the construct. Self-reported overactivity reflects an individual's “belief,” collected retrospectively, that their earlier activity levels have resulted in increased levels of pain. This may be different to an individual actually engaging in activity in a way that significantly exacerbates pain. In this study, a 5-day observational study design was used to investigate the validity of overactivity as a construct by examining the relationship between a self-report measure of overactivity, patterns of pain, and objectively measured physical activity over time. A sample of 68 adults with chronic pain completed a questionnaire investigating self-reported habitual engagement in overactivity and activity avoidance behaviour, before commencing 5 days of data collection. Over the 5-day period, participants wore an activity monitor and recorded their pain intensity 6 times a day using a handheld computer. Associations were found between (1) high levels of pain and both high overactivity and high avoidance, (2) high levels of overactivity and more variation in pain and objective activity across days, and (3) high levels of overactivity and the reoccurrence of prolonged activity engagement followed by significant pain increases observed in data sets. These results offer some preliminary support for the validity of overactivity as a legitimate construct in chronic pain. PMID:26067583

    This study examines maladaptive pain-related fear-avoidance and endurance coping in subgroups of patients with chronic back pain. Hypotheses were derived from the avoidance-endurance model of pain [Hasenbring M. Attentional control of pain and the process of chronification. In: Sandkühler J, Bromm B, Gebhart GF, editors. Progress in pain research, vol. 129. New York: Elsevier; 2000. p. 525-34.], which assumes that endurance coping (cognitive, behavioral tendency to endure severe pain to finish current activities irrespective of pain increases) leads to overuse of muscles, joints, and discs with an increase of pain as long-term consequence. Participants were 120 patients referred for treatment of chronic pain to General Practices. They were classified as 'dysfunctional-DYS' (15.8%), 'interpersonally distressed-ID' (10.8%), and 'adaptive copers-AC' (61.7%) based on the Multidimensional Pain Inventory [Kerns RD, Turk DC, Rudy TE. The West Haven-Yale Multidimensional Pain Inventory (WHYMPI). Pain 1985;23:345-56.] and compared on measures of pain-related fear-avoidance coping (anxiety/depression; help-/hopelessness; catastrophizing; avoidance of social/physical activity) and endurance coping (positive mood; thought suppression; endurance behavior) using the Kiel Pain Inventory [Hasenbring M. The Kiel Pain Inventory-Manual. Three questionnaire scales for assessment of pain-related cognitions, emotions and copying strategies. Bern:Huber; 1994.]. Multivariate analysis of variance indicated that groups differed significantly for pain-related fear-avoidance and endurance coping, even after control for pain intensity and depression. Univariate effects revealed that patients classified as DYS reported more anxiety/depression, help-/hopelessness, and catastrophizing than did those classified as AC. Furthermore, the DYS group showed more thought suppression compared to AC; however, subgroups did not differ significantly with regard to avoidance of social and physical activity

    This paper examines current knowledge about putative "pro-algesic" dietary components, and discusses whether limiting the intake of these substances can help improve chronic pain. Although there is a common impression that numerous food components, natural and synthetic, can cause or worsen pain symptoms, very few of these substances have been investigated. This article focuses on four substances, monosodium glutamate, aspartame, arachidonic acid, and caffeine, where research shows that overconsumption may induce or worsen pain. For each substance, the mechanism whereby it may act to induce pain is examined, and any clinical trials examining the effectiveness of reducing the intake of the substance discussed. While all four substances are associated with pain, decreased consumption of them does not consistently reduce pain. PMID:26900907

    When the medical records for John Fitzgerald Kennedy were made public, it became clear that the 35th President of the United States suffered greatly from a series of medical illnesses from the time he was a toddler until his assassination in November of 1963. Aside from having Addison disease, no condition seemed to cause him more distress than did his chronic low back pain. A number of surgical procedures to address the presumed structural cause of the pain resulted in little relief and increased disability. Later, a conservative program, including trigger point injections and exercises, provided modest benefit. Herein, the mechanisms underlying his pain are evaluated based on more contemporary pain research. This reconceptualizing of John Fitzgerald Kennedy's pain could serve as a model for other cases where the main cause of the pain is presumed to be located in the periphery.

    Chronic pain is very common in all European countries, with musculoskeletal problems predominating. About 1% of the adult population develops a syndrome of chronic muscle pain, fibromyalgia (FMS), characterized by multiple tender points, back or neck pain, and a number of associated problems from other organs, including a high frequency of fatigue. Evidence points to central sensitization as an important neurophysiological aberration in the development of FMS. Importantly, these neurological changes may result from inadequately treated chronic focal pain problems such as osteoarthritis or myofascial pain. It is important for health professionals to be aware of this syndrome and to diagnose the patients to avoid a steady increase in diagnostic tests. On the other hand, patients with chronic widespread pain have an increased risk of developing malignancies, and new or changed symptoms should be diagnosed even in FMS. In rheumatology practice it is especially important to be aware of the existence of FMS in association with immune inflammatory diseases, most commonly lupus and rheumatoid arthritis. Differential diagnoses are other causes of chronic pain, e.g. thyroid disease. The costs of this syndrome are substantial due to loss of working capability and direct expenses of medication and health-system usage. Fibromyalgia patients need recognition of their pain syndrome if they are to comply with treatment. Lack of empathy and understanding by healthcare professionals often leads to patient frustration and inappropriate illness behavior, often associated with some exaggeration of symptoms in an effort to gain some legitimacy for their problem. FMS is multifaceted, and treatment consists of both medical interventions, with emphasis on agents acting on the central nervous system, and physical exercises.

    All generalist and specialist clinicians are likely to encounter torture survivors among refugees and asylum seekers. A minority of people survive torture and a smaller minority reach a developed country; those who do tend to be the more resilient and resourceful. They have many health, social and welfare problems; persistent pain in the musculoskeletal system is one of the most common. There is little specific evidence on pain in survivors of torture; the guidelines on interdisciplinary specialist management are applicable. Most of the literature on refugee survivors of torture has an exclusive focus on psychological disorders, with particularly poor understanding of pain problems. This article summarizes the current status of assessment and treatment of pain problems in the torture survivor.

    Purpose Tobacco smoke exposure continues to be the leading preventable risk factor for many diseases and has the potential to be a risk factor for chronic pain. The purpose of this study is to determine the relationship of chronic pain with smoking, secondhand smoke exposure and non-smoking using serum cotinine (and self-report of living with someone who smokes in the home) to identify the tobacco exposure groups. Methods The National Health and Nutrition Examination Survey (NHANES) 2003–2004 was used for this study. Participants were queried about pain duration and had serum cotinine levels determined during the course of the NHANES examination/survey. Participants, ages 20 years and above, with complete data on chronic pain, cotinine level, sex, race/ethnicity, and responses concerning living with someone who smoked in the home were included in the study (n=4429). Results The adjusted odds ratio of tobacco smoke exposure on chronic pain was 1.67 (95% CI: 1.08, 2.59; p=0.0220) for participants with a serum cotinine level >10 ng/mg (smokers) as compared with individuals who had a non-detectable serum cotinine level. For individuals with a serum cotinine level >0.011 ng/mg to 10 ng/mg who identified as living with someone who smoked in the home, the adjusted odds ratio was 0.88 (95% CI: 0.47, 1.65; p=0.6785) as compared with individuals who had a non-detectable serum cotinine level. Conclusion Chronic pain is a complex situation with many factors affecting it. Similarly, smoking is a complex addiction. The interplay of chronic pain and cotinine levels in this study were significant. PMID:26835515

    [Purpose] Through core strength training, patients with chronic low back pain can strengthen their deep trunk muscles. However, independent training remains challenging, despite the existence of numerous core strength training strategies. Currently, no standardized system has been established analyzing and comparing the results of core strength training and typical resistance training. Therefore, we conducted a systematic review of the results of previous studies to explore the effectiveness of various core strength training strategies for patients with chronic low back pain. [Methods] We searched for relevant studies using electronic databases. Subsequently, we evaluated their quality by analyzing the reported data. [Results] We compared four methods of evaluating core strength training: trunk balance, stabilization, segmental stabilization, and motor control exercises. According to the results of various scales and evaluation instruments, core strength training is more effective than typical resistance training for alleviating chronic low back pain. [Conclusion] All of the core strength training strategies examined in this study assist in the alleviation of chronic low back pain; however, we recommend focusing on training the deep trunk muscles to alleviate chronic low back pain.

    Common sequelae following a traumatic event include chronic pain and posttraumatic stress disorder (PTSD). Over the last decade, the literature relating to PTSD has become progressively more sophisticated, resulting in well-supported theories and treatments for sufferers. Equivalent research relating to chronic pain has more recently gathered momentum. However, to date there has been minimal attention devoted to the concurrence of the two disorders, even though high comorbidity has been noted. This review begins by briefly summarizing the literature relating to the two disorders in terms of symptoms, prevalence and comorbidity. It explicates the major psychological theories of chronic pain and PTSD and reviews the evidence relating what factors maintain the disorders. A number of pathways by which chronic pain and PTSD may be mutually maintaining are highlighted. We conclude that chronic pain and PTSD are mutually maintaining conditions and that there are several pathways by which both disorders may be involved in the escalation of symptoms and distress following trauma. Treatment implications are considered, as are issues for future research.

    Exercise therapy is the most widely used type of conservative treatment for low back pain. Systematic reviews have shown that exercise therapy is effective for chronic but not for acute low back pain. During the past 5 years, many additional trials have been published on chronic low back pain. This articles aims to give an overview on the effectiveness of exercise therapy in patients with low back pain. For this overview, existing Cochrane reviews for the individual interventions were screened for studies fulfilling the inclusion criteria, and the search strategy outlined by the Cochrane Back Review Group (CBRG) was followed. Studies were included if they fulfilled the following criteria: (1) randomised controlled trials,(2) adult (> or =18 years) population with chronic (> or =12 weeks) nonspecific low back pain and (3) evaluation of at least one of the main clinically relevant outcome measures (pain, functional status, perceived recovery or return to work). Two reviewers independently selected studies and extracted data on study characteristics, risk of bias and outcomes at short-term, intermediate and long-term follow-up. The GRADE approach (GRADE, Grading of Recommendations Assessment, Development and Evaluation) was used to determine the quality of evidence. In total, 37 randomised controlled trials met the inclusion criteria and were included in this overview. Compared to usual care, exercise therapy improved post-treatment pain intensity and disability, and long-term function. The authors conclude that evidence from randomised controlled trials demonstrated that exercise therapy is effective at reducing pain and function in the treatment of chronic low back pain. There is no evidence that one particular type of exercise therapy is clearly more effective than others. However, effects are small and it remains unclear which subgroups of patients benefit most from a specific type of treatment. PMID:20227641

    Patients with chronic fatigue syndrome (CFS) experience chronic musculoskeletal pain which is even more debilitating than fatigue. Scientific research data gathered around the world enables clinicians to understand, at least in part, chronic musculoskeletal pain in CFS patients. Generalized joint hypermobility and benign joint hypermobility syndrome appear to be highly prevalent among CFS sufferers, but they do not seem to be of any clinical importance. On the other hand, pain catastrophizing accounts for a substantial portion of musculoskeletal pain and is a predictor of exercise performance in CFS patients. The evidence concerning pain catastrophizing is supportive of the indirect evidence of a dysfunctional pain processing system in CFS patients with musculoskeletal pain. CFS sufferers respond to incremental exercise with a lengthened and accentuated oxidative stress response, explaining muscle pain, postexertional malaise, and the decrease in pain threshold following graded exercise in CFS patients. Applying the scientific evidence to the manual physiotherapy profession, pacing self-management techniques and pain neurophysiology education are indicated for the treatment of musculoskeletal pain in CFS patients. Studies examining the effectiveness of these strategies for CFS patients are warranted.

  13. Chronic Stress, Cortisol Dysfunction, and Pain: A Psychoneuroendocrine Rationale for Stress Management in Pain Rehabilitation

    2014-01-01

    Pain is a primary symptom driving patients to seek physical therapy, and its attenuation commonly defines a successful outcome. A large body of evidence is dedicated to elucidating the relationship between chronic stress and pain; however, stress is rarely addressed in pain rehabilitation. A physiologic stress response may be evoked by fear or perceived threat to safety, status, or well-being and elicits the secretion of sympathetic catecholamines (epinephrine and norepinepherine) and neuroendocrine hormones (cortisol) to promote survival and motivate success. Cortisol is a potent anti-inflammatory that functions to mobilize glucose reserves for energy and modulate inflammation. Cortisol also may facilitate the consolidation of fear-based memories for future survival and avoidance of danger. Although short-term stress may be adaptive, maladaptive responses (eg, magnification, rumination, helplessness) to pain or non–pain-related stressors may intensify cortisol secretion and condition a sensitized physiologic stress response that is readily recruited. Ultimately, a prolonged or exaggerated stress response may perpetuate cortisol dysfunction, widespread inflammation, and pain. Stress may be unavoidable in life, and challenges are inherent to success; however, humans have the capability to modify what they perceive as stressful and how they respond to it. Exaggerated psychological responses (eg, catastrophizing) following maladaptive cognitive appraisals of potential stressors as threatening may exacerbate cortisol secretion and facilitate the consolidation of fear-based memories of pain or non–pain-related stressors; however, coping, cognitive reappraisal, or confrontation of stressors may minimize cortisol secretion and prevent chronic, recurrent pain. Given the parallel mechanisms underlying the physiologic effects of a maladaptive response to pain and non–pain-related stressors, physical therapists should consider screening for non–pain-related stress to

  16. Problems in the Differential Diagnosis of Chronic Pain

    1990-01-01

    Differential diagnosis is the systematic consideration of the possible cause of signs and symptoms. It requires establishing an anatomic diagnosis, in which the site of pathology is identified, and then an etiiologic diagnosis of the causal pathologic agent. The differential diagnosis is based on a knowledge of the pathophysiology of 1) the presenting signs and symptoms, and 2) the natural history of various diseases and their causative agents. Consequently, the accuracy and reliability of the differential diagnosis is limited by a lack of knowledge about the pathophysiology of various diseases that produce chronic pain. Most painful conditions affecting ectodermally derived tissues are relatively easily localized; the major problems are in the diagnosis of central nervous system pain syndromes and in our knowledge about the pathophysiology of painful neurologic disorders. The anatomic diagnosis of painful diseases of mesodermal and endodermal tissues may be difficult because of the phenomena of referred pain and tenderness. The etiologic diagnosis is made difficult by our lack of knowledge about how various pathologic processes activate nociceptors in these tissues. Finally, the differential diagnosis of chronic pain requires information about the psychological characteristics of the patient and how emotional and higher cognitive functions influence the perception of pain.

    Interdisciplinary pain rehabilitation programs (IPRPs) are based on a functional restoration approach to treating complex chronic pain conditions. With a greater appreciation for a biopsychosocial approach to more effectively manage patients with chronic pain has come the development of more comprehensive treatment programs with less of a biomedical emphasis (i.e., interventional therapy, unimodal physical therapy, and passive modalities) and more of a biopsychosocial one. Interdisciplinary programs involve the use of multiple disciplines such as physical and occupational therapy, pain psychology, medical pain management, vocational rehabilitation, relaxation training, and nursing educations. Multiple psychometric tools are used in the assessment process and along treatment to better assess outcomes. This article will examine components of IPRPs, discuss desirable features of successful programs and teams, and more closely review four established outpatient pain programs in the United States. A greater understanding of the unique features and shared values of successful programs will help one better understand how these programs can be more widely used and available. The review will also highlight common psychometric outcomes tools used in assessing patients and monitoring outcomes. Most importantly, the review will help to answer a common question, even among pain physicians: "What goes on in those chronic pain programs?"

    Chronic postsurgical pain (CPSP) is a pain syndrome that has attracted attention for more than 10 years. CPSP is a pain syndrome that develops postoperatively and lasts for at least 2 months in the absence of other causes for pain (eg, recurrence of malignancy, chronic infection, and so forth). Pain continuing from a preexisting disease is not considered as CPSP. In this article, the authors discuss the etiopathogenesis of CPSP and interventions that can help prevent and treat this condition.

    A sensitive non-invasive diagnostic test for intrinsic ligament rupture in patients with chronic wrist pain has still to be found. Differential displacement of the scaphoid, lunate and triquetrum can in some instances be seen during arthroscopy of acute wrist injuries and also on overdistraction of distal radial fractures with an external fixator. We performed a prospective study on 20 patients with chronic wrist pain using 2 kg and 5 kg traction radiographs without and with the addition of an ischaemic block, to assess differential displacement as a diagnostic criterion for intrinsic ligament rupture. Arthroscopy was used as arbiter of diagnosis. The sensitivity ranged from 14% to 57% and the specificity ranged from 53.7% to 100% according to the amount of traction and ischaemic block. In view of these poor results we conclude the stretch test has no additional value in the preoperative assessment of chronic wrist pain. PMID:8077822

    Chronic nonmalignant pain frequently results in significant physical, behavioral, psychological, social, and spiritual issues for patients and their families. It is often misunderstood and unsuccessfully managed. Advanced practice nurses who are knowledgeable about chronic pain and the complex biopsychosocial-spiritual needs of this patient population serve an important role in recognizing these patients and intervening appropriately in their care. The purpose of this two-part article is to provide that information. Part I [Clinical Excellence for Nurse Practitioners, 3 (4), 192-204] outlined the pathophysiology, assessment, biopsychosocial-spiritual aspects, and pharmacologic treatment of chronic pain. In Part II, a variety of nonpharmacologic and self-management interventions one can use in the primary care setting to treat these difficult health problems are introduced. PMID:11858295

    Background This study aimed to answer three questions related to chronic myofascial pain syndrome (MPS): 1) Is the motor cortex excitability, as assessed by transcranial magnetic stimulation parameters (TMS), related to state-trait anxiety? 2) Does anxiety modulate corticospinal excitability changes after evoked pain by Quantitative Sensory Testing (QST)? 3) Does the state-trait anxiety predict the response to pain evoked by QST if simultaneously receiving a heterotopic stimulus [Conditional Pain Modulation (CPM)]? We included females with chronic MPS (n = 47) and healthy controls (n = 11), aged 19 to 65 years. Motor cortex excitability was assessed by TMS, and anxiety was assessed based on the State-Trait Anxiety Inventory. The disability related to pain (DRP) was assessed by the Profile of Chronic Pain scale for the Brazilian population (B:PCP:S), and the psychophysical pain measurements were measured by the QST and CPM. Results In patients, trait-anxiety was positively correlated to intracortical facilitation (ICF) at baseline and after QST evoked pain (β = 0.05 and β = 0.04, respectively) and negatively correlated to the cortical silent period (CSP) (β = -1.17 and β = -1.23, respectively) (P <0.05 for all comparisons). After QST evoked pain, the DRP was positively correlated to ICF (β = 0.02) (P < 0.05). Pain scores during CPM were positively correlated with trait-anxiety when it was concurrently with high DRP (β = 0.39; P = 0.02). Controls’ cortical excitability remained unchanged after QST. Conclusions These findings suggest that, in chronic MPS, the imbalance between excitatory and inhibitory descending systems of the corticospinal tract is associated with higher trait-anxiety concurrent with higher DRP.

To complement existing reviews of acupuncture and moxibustion for chronic pain and to provide more detailed discussion and analysis, we did a literature search using ‘Igaku Chuo Zasshi Wed’ (Japana Centra Revuo Medicina) and ‘Citation Information by National Institute of Information’ covering the period 1978–2006. Original articles and case reports of acupuncture and moxibustion treatment of chronic pain were included. Animal studies, surveys, and news articles were excluded. Two independent reviewers extracted data from located articles in a pre-defined structured way, and assessed the likelihood of causality in each case. We located 57 papers written in Japanese (20 full papers, 37 case reports). Conditions examined were headache (12 trials), chronic low back pain (9 trials), rheumatoid arthritis (8 trials), temporomandibular dysfunction (8 trials), katakori (8 trials) and others (12 trials). While 23 were described as clinical control trials (CCTs), 11 employed a quasi-random method. Applying the 5-point Jadad quality assessment scoring system, the mean score was 1.5 ± 1.3 (SD). Eleven (52%) of the CCTs were conducted to determine a more effective procedure for acupuncture; these compared a certain type of acupuncture with another type of acupuncture or specific additional points. In particular, the trigger point acupuncture was widely used to treat chronic low back pain in Japan. Many reports of chronic pain treatment by acupuncture and moxibustion are listed in Japanese databases. From the data, we conclude that there is limited evidence that acupuncture is more effective than no treatment, and inconclusive evidence that trigger point acupuncture is more effective than placebo, sham acupuncture or standard care.

    The present study measured the effects of catastrophizing self-statements and positive coping self-statements on cold pressor-induced pain. Participants were 58 adult chronic pain patients with current facial pain. It was hypothesized that catastrophizing would lead to a decrease in pain endurance whereas positive coping would lead to an increase in pain endurance. It was also hypothesized that catastrophizing would lead to an increase in peak pain intensity whereas positive coping would lead to a decrease in peak pain intensity. At pretest, participants submerged their nondominant hand in the cold pressor. Pain sensitivity ranges (PSR) were subsequently determined by calculating the difference between tolerance and threshold times. Ratings of peak pain intensity were measured using a pressure sensitive bladder/transducer. Participants underwent random assignment to either a catastrophizing group or a positive coping self-statement group. ANCOVA results revealed that on average, participants employing catastrophizing statements as a coping strategy experienced significantly lower PSR (M = 35.53, SD = 39.71) compared to participants employing positive coping self-statements (M = 73.70, SD = 86.14) when controlling for pretest PSR. Group assignment had no significant influence on peak pain intensity ratings. Thus, our results reveal that manipulation of coping causes changes in pain endurance. PMID:21197299

    A large number of treatments were used for patients with chronic low back pain. Frequent episodes have been reported very high. Although balneotherapy was found effective in this disease, there are not well-designed studies. We aimed to determine the effectiveness of balneotherapy versus physical therapy in patients with chronic low back pain. Exercise was added to both treatment programs. Sixty patients with chronic low back pain were randomly divided into two groups. Physical modalities plus exercise were applied to group 1, and group 2 was received balneotherapy plus exercise for ten sessions. The following parameters were measured: visual analogue scale at rest and movement for pain, paracetamol dose, manual muscle test for lumber muscles, modified Schoeber' test, Oswestry disability index, and Short-Form 36 at the beginning and end of the therapies and at the 3 months follow-up. The statistical analyses were performed using the SPSS 10.0 program. Both groups achieved significant improvements within themselves. But balneotherapy groups were improved at back extensor muscle test (P < 0.05), modified Schoeber's test (P < 0.03), Oswestry disability index, and the some scores of SF 36 (energy vitality, social function, role limitations related to physical problems, and general health P < 0.05). Balneotherapy combined with exercise therapy had advantages than therapy with physical modalities plus exercise in improving quality of life and flexibility of patients with chronic low back pain.

    The prevalence of fibromyalgia in the general population was found to be 2% and increased with age. Multiple traumatic factors, including sexual and physical abuse, may be important initiating events. The most important pathophysiologic studies in fibromyalgia included evidence of altered blood flow to the brain and hypothalamic-pituitary-adrenal dysfunction. The prevalence of chronic fatigue syndrome is much less than that of fibromyalgia. Epidemiologic studies demonstrated that chronic fatigue and symptoms of fibromyalgia are distributed as continuous variables in the general population. No association between chronic fatigue and initial infections was seen in primary care practices.

    This study evaluates group treatment for women suffering from chronic pelvic pain. The concept of group treatment was based on psychosomatic and physio-therapeutical principles and on cognitive and operant behavioral therapy. Each group was composed of up to six women suffering from chronic pelvic pain, and two physiotherapists. Each group treatment session lasted 2.5 h per week for a period of 10 weeks. The women completed questionnaires and pain drawings four times during the treatment period from the beginning of the period till 15 months later. During 13 group treatment periods 53 women accomplished the treatment. Before the treatment the women had experienced pain for an average period of 5 years and 9 months (ranging from 6 months to 22 years). The women's descriptions of the changes derived from group treatment were analyzed according to the Grounded Theory Method. A methodical triangulation of quantitative and qualitative data as well as analyzes of the drawings were applied. One year after the end of the treatment, 39% of the women were pain-free. The average level of pain measured according to the Visual Analog Scale was reduced from 2.8 to 0.9 (p < 0.01). The intake rate of analgesics was reduced from an average of 8.5 units to 0.9 units per week (p < 0.01). Furthermore a reduction in the use of the National Health Service and increases in gainful employment were registered. By means of the Grounded Theory Analysis a model of the development process was elaborated. The process begins with the development of self-knowledge, followed by the woman assuming self responsibility for her own life and performing self-activeness. During the process the woman increases her feeling of self-control and personal mastery of her emotions. The women's pain drawings improved, resulting in more detailed drawings, the color intensity abating, the extent of pains declining, and the outlines blurring. In conclusion this kind of group treatment brings the women relief from

    Pain and inflammation in the absence of infection are hallmarks in chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) patients. The etiology of CP/CPPS is unclear, and autoimmunity has been proposed as a cause. Experimental autoimmune prostatitis (EAP) models have long been used for studying CP/CPPS. Herein, we studied prostate inflammation induction and chronic pelvic pain development in EAP using IL-12p40-KO, IL-4-KO, IL-17-KO, and wild-type (C57BL/6) mice. Prostate antigen (PAg) immunization in C57BL/6 mice induced specific Th1 and Th17 immune responses and severe prostate inflammation and cell infiltration, mainly composed of CD4 T cells and macrophages. Moreover, chronic pelvic pain was evidenced by increased allodynia responses. In immunized IL-17-KO mice, the presence of a prominent PAg-specific Th1 immune response caused similar prostate inflammation and chronic pelvic pain. Furthermore, markedly high PAg-specific Th1 immune responses, exacerbated prostate inflammation, and chronic pelvic pain were detected in immunized IL-4-KO mice. Conversely, immunized IL-12p40-KO mice developed PAg-specific Th2 immune responses, characterized by high IL-4 secretion and neither infiltration nor damage in the prostate. As observed in wild-type control animals, IL12p40-KO mice did not evidence tactile allodynia responses. Our results suggest that, as in patients, chronic pelvic pain is a consequence of prostate inflammation. After PAg immunization, a Th1-associated immune response develops and induces prostate inflammation and chronic pelvic pain. The absence of Th1 or Th2 cytokines, respectively, diminishes or enhances EAP susceptibility. In addition, IL-17 showed not to be essential for pathology induction and chronic pelvic pain development.

    Patients with chronic pain have a multifactoral problem that exhibits both physical and psychosocial symptoms. Evaluation includes determination of the physical diagnosis and psychosocial contributing factors on an equal and integrated basis. Contributing factors include any factor that plays a role in initiation and perpetuation or results from and thus, complicates the problem. Management follows with both reduction of contributing factors and treatment of the diagnosis. Contributing factors are classified as biological, behavioral, social, cognitive, emotional, and environmental. Individual factors in each group for chronic craniofacial pain are reviewed.

    When assessing women with chronic vulvar pain, women's health physical therapists search for comorbid mechanical components (including musculoskeletal, fascial, and visceral) and other disorders that may contribute to or be caused by chronic vulvar pain (CVP). Pelvic floor hypertonicity is a key perpetuating factor for CVP. Comprehensive physical therapy evaluation and suggested physical therapy interventions are described. Anatomy of the pelvis, common evaluative findings, and specifics for pelvic floor muscle rehabilitation are presented. Normalization of pelvic floor muscle function contributes to the reduction of CVP. Successful treatment includes the identification and treatment of co-existing physical abnormalities throughout the trunk and pelvis.

    Juvenile fibromyalgia in children with sickle cell disease has not been reported in the literature. We report an adolescent patient with sickle cell whose pain symptoms progressed from having recurrent acute sickle cell pain crisis episodes to a chronic pain syndrome over several years. He was eventually diagnosed with juvenile fibromyalgia based on the clinical history and myofascial tender points and his pain symptoms responded better to multidisciplinary strategies for chronic fibromyalgia pain. Chronic pain in sickle cell disease is an area of poor research, and in addition there is inconsistency in the definition of chronic pain in sickle cell disease. Central sensitisation to pain is shown to occur after recurrent painful stimuli in a genetically vulnerable individual. In a chronic pain condition such as fibromyalgia central sensitisation is thought to play a key role. Fibromyalgia should be considered as one of the main differential diagnosis in any sickle cell patient with chronic pain.

    Neural circuits that determine the perception and modulation of pain remain poorly understood. The prefrontal cortex (PFC) provides top-down control of sensory and affective processes. While animal and human imaging studies have shown that the PFC is involved in pain regulation, its exact role in pain states remains incompletely understood. A key output target for the PFC is the nucleus accumbens (NAc), an important component of the reward circuitry. Interestingly, recent human imaging studies suggest that the projection from the PFC to the NAc is altered in chronic pain. The function of this corticostriatal projection in pain states, however, is not known. Here we show that optogenetic activation of the PFC produces strong antinociceptive effects in a rat model (spared nerve injury model) of persistent neuropathic pain. PFC activation also reduces the affective symptoms of pain. Furthermore, we show that this pain-relieving function of the PFC is likely mediated by projections to the NAc. Thus, our results support a novel role for corticostriatal circuitry in pain regulation. PMID:25834050

    According to the Institute of Medicine (IOM) report on pain, chronic pain affects an estimated 116 million American adults and costs the nation more than $600 billion each year in medical treatment and lost worker productivity. Many individuals with chronic pain undergo surgical procedures. Safe and effective treatment of their postoperative pain can present a significant challenge to the health care team but is essential to their optimal recovery. Administrators in a community hospital in central Pennsylvania identified a need to improve the care of their patients with chronic pain and supported a hospital-wide initiative to address various aspects of this population's hospital experience. This article presents the first phase of an evidence-based practice project that focused on improving the perioperative pain management in patients with chronic pain who receive long-acting opioids for the treatment of chronic pain before admission for surgery.

    Chronic pain in children and adolescents is associated with major disruption to developmental experiences crucial to personal adjustment, quality of life, academic, vocational and social success. Caring for these patients involves understanding cognitive, affective, social and family dynamic factors associated with persistent pain syndromes. Evaluation and treatment necessitate a comprehensive multimodal approach including psychological and behavioral interventions that maximize return to more developmentally appropriate physical, academic and social activities. This article will provide an overview of major psychosocial factors impacting on pediatric pain and disability, propose an explanatory model for conceptualizing the development and maintenance of pain and functional disability in medically difficult-to-explain pain syndromes, and review representative evidence-based cognitive behavioral and systemic treatment approaches for improving functioning in this pediatric population.

    Primary sensory neurons in the DRG play an essential role in initiating pain by detecting painful stimuli in the periphery. Tissue injury can sensitize DRG neurons, causing heightened pain sensitivity, often leading to chronic pain. Despite the functional importance, how DRG neurons function at a population level is unclear due to the lack of suitable tools. Here we developed an imaging technique that allowed us to simultaneously monitor the activities of >1,600 neurons/DRG in live mice and discovered a striking neuronal coupling phenomenon that adjacent neurons tend to activate together following tissue injury. This coupled activation occurs among various neurons and is mediated by an injury-induced upregulation of gap junctions in glial cells surrounding DRG neurons. Blocking gap junctions attenuated neuronal coupling and mechanical hyperalgesia. Therefore, neuronal coupling represents a new form of neuronal plasticity in the DRG and contributes to pain hypersensitivity by "hijacking" neighboring neurons through gap junctions. PMID:27568517

    This two-phase study was conducted to identify relevant domains of patient-reported outcomes from the perspective of people who experience chronic pain. In Phase 1, focus groups were conducted to generate a pool of patient outcome-related domains and their components. The results of the focus groups identified 19 aspects of their lives that were significantly impacted by the presence of their symptoms and for which improvements were important criteria they would use in evaluating the effectiveness of any treatment. Phase 2 was conducted to examine the importance and relevance of domains identified from a much larger and diverse sample of people with chronic pain. A survey was developed and posted on the American Chronic Pain Association website. Participants were asked to rate the importance of each item or domain identified by the focus groups on a scale of 0 to10 (i.e., 0="not at all important" and 10="extremely important"). The survey was completed by 959 individuals. The results indicate that all 19 aspects of daily life derived from the focus groups were considered important with a majority of respondents indicating a score of 8 or greater. In addition to pain reduction, the most important aspects were enjoyment of life, emotional well-being, fatigue, weakness, and sleep-related problems. Chronic pain clearly impacts health-related quality of life. The results of the two phases of the study indicate that people with chronic pain consider functioning and well-being as important areas affected by the presence of symptoms and as appropriate targets of treatment. These multiple outcomes should be considered when evaluating the efficacy and effectiveness of chronic pain treatments.

    Background Chronic back pain is relatively resistant to unimodal therapy regimes. The aim of this study was to introduce and evaluate the short-term outcome of a three-week intensive multidisciplinary outpatient program for patients with back pain and sciatica, measured according to decrease of functional impairment and pain. Methods The program was designed for patients suffering from chronic back pain to provide intensive interdisciplinary therapy in an outpatient setting, consisting of interventional injection techniques, medication, exercise therapy, back education, ergotherapy, traction, massage therapy, medical training, transcutaneous electrical nerve stimulation, aquatraining, and relaxation. Results Based on Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS) scores, a significant improvement in pain intensity and functionality of 66.83% NRS and an ODI of 33.33% were achieved by our pain program within 3 weeks. Conclusion This paper describes the organization and short-term outcome of an intensive multidisciplinary program for chronic back pain on an outpatient basis provided by our orthopedic department, with clinically significant results.

    Self-discrepancy occurs when a person feels the failure to fulfill one's hopes or responsibilities. Although self-discrepancy has been widely examined to elucidate patients' chronic pain adjustment, the underlying mechanism is unclear. The present study proposes that the effect of self-discrepancy on pain outcomes is accounted for by psychological inflexibility, which involves the psychological processes that guide behaviors in the pursuit of goals and values. One-hundred patients with chronic pain were recruited from a public hospital. They were invited to participate in a semi-structured interview regarding their self-discrepancy and complete self-reported questionnaires regarding their psychological inflexibility and pain outcomes. The results confirmed that psychological inflexibility partly accounts for the variance observed between self-discrepancy and pain outcomes. The current study provides additional insight into the mechanism underpinning the impact of self-discrepancy on patients' pain adjustment and offers clinical implications regarding the use of acceptance commitment therapy for chronic pain management.

    2015-01-01

    Pain sensing neurons in the periphery (called nociceptors) and the central neurons that receive their projections show remarkable plasticity following injury. This plasticity results in amplification of pain signaling that is now understood to be crucial for the recovery and survival of organisms following injury. These same plasticity mechanisms may drive a transition to a non-adaptive chronic pain state if they fail to resolve following the termination of the healing process. Remarkable advances have been achieved in the past two decades in understanding the molecular mechanisms that underlie pain plasticity following injury. The mechanisms bear a striking resemblance to molecular mechanisms involved in learning and memory processes in other brain regions, including the hippocampus and cerebral cortex. Here those mechanisms, their commonalities and subtle differences, will be highlighted and their role in causing chronic pain will be discussed. Arising from these data is the striking argument that chronic pain is a disease of the nervous system, which distinguishes this phenomena from acute pain that is frequently a symptom alerting the organism to injury. This argument has important implications for the development of disease modifying therapeutics. PMID:25744681

    Chronic pain and depression are coexisting entities with high simultaneous prevalence. Both are linked with early adversities. Early maladaptive schemas (EMS) can be seen as a reflection of these adversities. EMSs extensively indicate underlying psychic patterns and provide a good opportunity to detect covert processes and psychic shapes (latent factors), which create the basis of how people rate their schemas. The purpose of this study was to explore these latent, higher order schema factors (SF) and to find out how they are associated with pain intensity or depression in chronic pain patients and a control sample. The study subjects consisted of 271 first-visit pain patients and 331 control participants. Sociodemographic and pain data were gathered by questionnaire; 18 EMSs were measured with the Young Schema Questionnaire (short form) and depressiveness was measured with the Beck Depression Inventory, Version II. Exploratory factor and regression analyses were used. The chronic pain patient group showed two SFs. The first SF showed a shameful, defective, socially isolated, failure, emotionally inhibited, deprived, submissive and resigned pattern. The second SF showed a demanding, approval seeking, self-sacrificing and punitive pattern. SF1 predicted more than half of the depressiveness in the pain patient sample. A three-factor structure was found in the control sample, and SFs 1 and 3 together predicted almost one-third of depressiveness. The pain patient and the control groups had a different, higher order factor structure. We assume that SF1 in the pain patients reflected a rather serious, undefined early psychic trauma and was also associated with their depressiveness. PMID:21210495

    Chronic pain following surgery limits social activity, interferes with work and causes emotional suffering. A major component of such pain is is reported as “resting” or spontaneous pain with no apparent external stimulus. Although experimental animal models can simulate the stimulus-evoked chronic pain that occurs after surgery, there have been no studies of spontaneous chronic pain in such models. Here the Conditioned Place Preference (CPP) paradigm was used to reveal resting pain after experimental thoracotomy. Male Sprague-Dawley rats received a thoracotomy with 1 hour rib retraction, resulting in evoked tactile hypersensitivity, previously shown to last for at least 9 weeks. Intraperitoneal injections of morphine (2.5 mg/kg) or gabapentin (40mg/kg) gave equivalent 2-3h long relief of tactile hypersensitivity, when tested 12-14 days post-operative. In separate experiments, single trial CPP was conducted 1 week before thoracotomy and then 12 days (gabapentin) or 14 days (morphine) after surgery, followed the next day by one conditioning sesssion with morphine or gabapentin, both vs saline. The gabapentin-conditioned, but not the morphine-conditioned rats showed a significant preference for the analgesia-paired chamber, despite the two agents’ equivalent effect in relieving tactile allodynia. These results show that experimental thoracotomy in rats causes spontaneous pain, and that some analgesics, such as morphine, that reduce evoked pain do not also relieve resting pain, suggesting that pathophysiological mechanisms differ between these two aspects of long-term post-operative pain.

    Chronic musculoskeletal pain, such as low back pain, often appears in the presence of psychiatric comorbidities (e.g., depression, posttraumatic stress disorder (PTSD)), especially among U.S. military service members serving in the post-9/11 combat era. Although there has been much speculation about how to best address pain/trauma psychiatric symptom comorbidities, there are little available data to guide practice. The present study sought to examine how pre-treatment depression and PTSD influence outcomes in a functional restoration pain management program using secondary analysis of data from the Department of Defense-funded Functional and Orthopedic Rehabilitation Treatment (FORT) trial. Twenty-eight FORT completers were analyzed using a general linear model exploring how well depression and PTSD symptoms predict post-treatment pain (Visual Analog Scale (VAS) pain rating), disability (Oswestry Disability Index; Million Visual Analog Scale), and functional capacity (Floor-to-Waist and Waist-to-Eye Level progressive isoinertial lifting evaluation scores) in a sample of active duty military members with chronic musculoskeletal pain and comorbid depression or PTSD symptoms. Analysis revealed that pre-treatment depression and PTSD symptoms did not significantly predict rehabilitation outcomes from program completers. Implications of these findings for future research on trauma-related pain comorbidities are discussed. PMID:27417626

    This retrospective study investigated the influence of psychiatric comorbidity on pain perception and coping with pain in tertiary pain clinic patients, 427 treated for chronic low back pain (CLBP) and 629 for other forms of chronic pain (CG). No differences in psychosomatic dimensions were found between the two groups, but Italian Pain Questionnaire dimensions and intensity scores (t = 7.35; p < 0.0001) were higher in CLBP than in CG subjects. According to the Mini-International Neuropsychiatric Interview, CLBP patients also had a higher prevalence of lifetime major depressive episodes (χ2 = 4.96; p < 0.05), dysthymic disorder (χ2 = 4.64; p < 0.05), suicide risk (χ2 = 10.43; p < 0.01), and agoraphobia (χ2 = 6.31; p < 0.05) than CG patients did. The Multidimensional Pain Inventory showed a close association between CLBP and both agoraphobia (χ2 = 3.74; p < 0.05) and dysfunctional coping style (χ2 = 8.25; p < 0.01), which increased disability. Both agoraphobia and lifetime depression were associated with an overall increase in dimensions and pain intensity in CLBP, but not in CG. PMID:26153889

    Patient characteristics associated with the course and severity of low back pain (LBP) and disability have been the focus of extensive research, however, known characteristics do not explain much of the variance in outcomes. The relationship between anterior trunk pain (ATP) and LBP has not been explored, though mechanisms for visceral referred pain have been described. Study objectives were: (1) determine prevalence of ATP in chronic LBP patients, (2) determine whether ATP is associated with increased pain and disability in these patients, and (3) evaluate whether ATP predicts the course of pain and disability in these patients. In this study, spinal outpatient department patients mapped the distribution of their pain and patients describing pain in their chest, abdomen or groin were classified with ATP. Generalized estimating equations were performed to investigate the relationship between ATP and LBP outcomes. A total of 2974 patients were included and 19.6% of patients reported ATP. At all time points, there were significant differences in absolute pain intensity and disability in those with ATP compared with those without. The presence of ATP did not affect the clinical course of LBP outcomes. The results of this study suggest that patients who present with LBP and ATP have higher pain and disability levels than patients with localised LBP. Visceral referred pain mechanisms may help to explain some of this difference. PMID:24502844

Generalized estimating equations were performed to investigate the relationship between ATP and LBP outcomes. A total of 2974 patients were included and 19.6% of patients reported ATP. At all time points, there were significant differences in absolute pain intensity and disability in those with ATP compared with those without. The presence of ATP did not affect the clinical course of LBP outcomes. The results of this study suggest that patients who present with LBP and ATP have higher pain and disability levels than patients with localised LBP. Visceral referred pain mechanisms may help to explain some of this difference.

    Combined pharmacological treatments are the most used approach for neuropathic pain. Carbamazepine, an antiepileptic agent, is generally used as a third-line treatment for neuropathic pain and can be considered an option only when patients have not responded to the first- and second-line medications. In the case presented herein, a patient with neuropathic pain was treated using a combined pharmacological regimen. The patient's pain deteriorated, despite increasing the doses of opioids, when carbamazepine was discontinued, potentially because carbamazepine withdrawal disrupted the balance that was achieved by the multifaceted pharmacological regimen, thus inducing hyperalgesia. Interestingly, when carbamazepine was prescribed again, the patient's pain was successfully managed. Animal research has reported that carbamazepine can potentiate the analgesic effectiveness of morphine in rodent models of neuropathic pain and postoperative pain. This clinical case demonstrates that carbamazepine may have a synergistic effect on the analgesic effectiveness of morphine and may inhibit or postpone opioid-induced hyperalgesia. We postulate that a probable mechanism of action of carbamazepine may involve -aminobutyric acid-ergic potentiation and the interruption of glutamatergic function via N-methyl-D-aspartate receptors. Further research is warranted to clarify the analgesic action of carbamazepine and its potential use for the prevention of opioid-induced hyperalgesia in chronic neuropathic pain patients.

    This study reviewed the published literature evaluating multidisciplinary chronic pain treatment facilities to provide an overview of their availability, caseload, wait times, and facility characteristics. A systematic literature review was conducted using PRISMA guidelines following a search of MEDLINE, PsycINFO, and CINAHL databases. Inclusion criteria stipulated that studies be original research, survey more than one pain treatment facility directly, and describe a range of available treatments. Fourteen articles satisfied inclusion criteria. Results showed little consistency in the research design used to describe pain treatment facilities. Availability of pain treatment facilities was scarce and the reported caseloads and wait times were generally high. A wide range of medical, physical, and psychological pain treatments were available. Most studies reported findings on the percentage of practitioners in different health care professions employed. Future studies should consider using more comprehensive search strategies to survey facilities, improving clarity on what is considered to be a pain treatment facility, and reporting on a consistent set of variables to provide a clear summary of the status of pain treatment facilities. This review highlights important information for policymakers on the scope, demand, and accessibility of pain treatment facilities. PMID:27445618

    Chronic pain interrupts behaviour, interferes with functioning, and may affect a person's identity: their sense of self. We tested whether loss of role and personal attributes and current and past self-concept differentiation, predicted adjustment as indexed by measures of depression. Chronic pain patients (n=80) completed measures of pain (MPQ), disability (PDI), depression and anxiety (BDI, HADS). Measures of role and attribute loss and self-concept differentiation were derived from a Role-Attribute Test in which participants identified four social roles in four domains (friendship, occupation, leisure, family) and nominated two personal attributes in each role prior to pain onset and current. Participants reported mean losses of 3.38 roles, and 6.97 attributes. Greater losses were observed in friendship, occupation and leisure domains compared with the family domain. Multiple regression analyses revealed that after controlling for demographic and clinical differences, role and attribute loss predicted depression scores. There was no evidence that depression was associated with past self-concept differentiation. The results are discussed with reference to the methodology used and the relevance of self-identity to understand adjustment to chronic pain. PMID:14499455

    The prevalence of chronic widespread pain in the general population in Israel was comparable with reports from the USA, UK, and Canada. Comorbidity with fibromyalgia (FM) resulted in somatic hyperalgesia in patients with irritable bowel syndrome. One sixth of the subjects with chronic widespread pain in the general population were also found to have a mental disorder. Mechanisms involved in referred pain, temporal summation, muscle hyperalgesia, and muscle pain at rest were attenuated by the N-methyl-D-aspartate (NMDA) antagonist, ketamine, in FM patients. Delayed corticotropin release, after interleukin-6 administration, in FM was shown to be consistent with a defect in hypothalamic corticotropin-releasing hormone neural function. The basal autonomic state of FM patients was characterized by increased sympathetic and decreased parasympathetic systems tones. The severity of functional impairment as assessed by the Medical Outcome Survey Short Form (SF-36) discriminated between patients with widespread pain alone and FM patients. Chronic fatigue syndrome (CFS) occurred in about 0.42% of a random community-based sample of 28,673 adults in Chicago, Illinois. A significant clinical overlap between CFS and FM was reported. Cytokine dysregulation was not found to be a singular or dominant factor in the pathogenesis of CFS. A favorable outcome of CFS in children was reported; two thirds recovered and resumed normal activities. No major therapeutic trials in FM and CFS were reported over the past year.

  15. The need for knowledge translation in chronic pain

    One in five Canadians suffers from some form of persistent or chronic pain. The impact on individual lives, families and friends, the health services sector and the economy is huge. Reliable evidence is available that the burden of persistent pain can be markedly reduced when available knowledge is applied. Bridging the quality chasm between chronic pain and the care process will require a unique confluence of opinion from all stakeholders committed within a focused community of practice to address the impact of pain. Various levels of success in this regard have been demonstrated when there is exchange, synthesis and ethically sound application of research findings within a complex set of interactions among researchers and knowledge users. It is now critical to accelerate the capture of the benefits of research for Canadians through improved health, more effective and responsive services and products, and a strengthened health care system to bring about health reform and health care reform across Canada as it pertains to the one in five Canadians living with chronic, disabling pain. The overarching outcome of such an initiative needs to be promoted to sustain a balanced portfolio of curiosity-and needs-based research, which along with existing knowledge, can be mobilized and applied for the benefit of Canadians, the health care system and the economy.

    Objectives. This study was done to evaluate three bedside tests in discriminating visceral pain from somatic pain among women with chronic pelvic pain. Study Design. The study was an exploratory cross-sectional evaluation of 81 women with chronic pelvic pain of 6 or more months' duration. Tests included abdominal cutaneous allodynia (aCA), perineal cutaneous allodynia (pCA), abdominal and perineal myofascial trigger points (aMFTP) and (pMFTP), and reduced pain thresholds (RPTs). Results. Eighty-one women were recruited, and all women provided informed consent. There were 62 women with apparent visceral pain and 19 with apparent somatic sources of pain. The positive predictive values for pelvic visceral disease were aCA-93%, pCA-91%, aMFTP-93%, pMFTP-81%, and RPT-79%. The likelihood ratio (+) and 95% C.I. for the detection of visceral sources of pain were aCA-4.19 (1.46, 12.0), pCA-2.91 (1.19, 7.11), aMTRP-4.19 (1.46, 12.0), pMFTP-1.35 (0.86, 2.13), and RPT-1.14 (0.85, 1.52), respectively. Conclusions. Tests of cutaneous allodynia, myofascial trigger points, and reduced pain thresholds are easily applied and well tolerated. The tests for cutaneous allodynia appear to have the greatest likelihood of identifying a visceral source of pain compared to somatic sources of pain. PMID:22135736

    Chronic pain and posttraumatic stress disorder (PTSD) symptoms have been found to co-occur in adults; however, research has not examined this co-occurrence in adolescence, when pediatric chronic pain often first emerges. The aims of this study were to compare the frequency and intensity of PTSD symptoms and stressful life events in cohorts of youth with (n = 95) and without (n = 100) chronic pain and their parents and to determine the association between PTSD symptoms, health-related quality of life, and pain symptoms within the chronic pain sample. All participants completed questionnaire measures through an online survey. Findings revealed that youth with chronic pain and their parents had significantly higher levels of PTSD symptoms as compared with pain-free peers. More youth with chronic pain (32%) and their parents (20%) reported clinically significant elevations in PTSD symptoms than youth without chronic pain (8%) and their parents (1%). Youth with chronic pain also reported a greater number of stressful life events than those without chronic pain, and this was associated with higher PTSD symptoms. Among the chronic pain cohort, higher levels of PTSD symptoms were predictive of worse health-related quality of life and were associated with higher pain intensity, unpleasantness, and interference. Results suggest that elevated PTSD symptoms are common and linked to reduced functioning among youth with chronic pain. Future research is needed to examine PTSD at the diagnostic level and the underlying mechanisms that may explain why this co-occurrence exists.

    Chronic groin pain is one the most complex conditions encountered in the field of sports medicine. Conservative treatment is long lasting and the result of treatment is often uncer- tain and symptom recurrences are common, which can be very frustrating for both the patient and the physician. The complex etiology and uncertainties during treatment of chronic groin pain is the reason why some authors call it the Bermuda Triangle of sports medicine. In our prospective, 7-year study, 114 athletes with chronic groin pain resistant to conservative therapy were treated surgically. In 109 athletes with sports hernia, we performed nerve neurolysis along with resection of the genital branch of the genitofemoral nerve and we also reinforced the posterior wall of inguinal canal using a modified Shouldice technique. In 26 athletes that had concomitant adductor tendinosis and in 5 athletes with isolated tendinosis we performed tenotomy. Eighty-one of 83 patients with isolated sports hernia returned to sports within a mean of 4.4 (range, 3-16) weeks. Thirty-one athletes with adductor tenotomy returned to sports activity within a mean of 11.8 (range, 10-15) weeks. If carefully diagnosed using detailed history taking, physical examination and correct imaging techniques, chronic groin pain can be treated very successfully and quickly, so it need not be a Bermuda Triangle of sports medicine.

    Objectives: With growing evidence for the effectiveness of craniosacral therapy (CST) for pain management, the efficacy of CST remains unclear. This study therefore aimed at investigating CST in comparison with sham treatment in chronic nonspecific neck pain patients. Materials and Methods: A total of 54 blinded patients were randomized into either 8 weekly units of CST or light-touch sham treatment. Outcomes were assessed before and after treatment (week 8) and again 3 months later (week 20). The primary outcome was the pain intensity on a visual analog scale at week 8; secondary outcomes included pain on movement, pressure pain sensitivity, functional disability, health-related quality of life, well-being, anxiety, depression, stress perception, pain acceptance, body awareness, patients’ global impression of improvement, and safety. Results: In comparison with sham, CST patients reported significant and clinically relevant effects on pain intensity at week 8 (−21 mm group difference; 95% confidence interval, −32.6 to −9.4; P=0.001; d=1.02) and at week 20 (−16.8 mm group difference; 95% confidence interval, −27.5 to −6.1; P=0.003; d=0.88). Minimal clinically important differences in pain intensity at week 20 were reported by 78% within the CST group, whereas 48% even had substantial clinical benefit. Significant between-group differences at week 20 were also found for pain on movement, functional disability, physical quality of life, anxiety and patients’ global improvement. Pressure pain sensitivity and body awareness were significantly improved only at week 8. No serious adverse events were reported. Discussion: CST was both specifically effective and safe in reducing neck pain intensity and may improve functional disability and the quality of life up to 3 months after intervention.

    The aim of the study was to show the role of tools in the evaluation of chronic pain (CP) in general practitioner (GP) everyday clinical practice. The study was done by analyzing electronic database of the first visits of 1090 CP patients referred to the Pain Clinic of the Karlovac General Hospital, Karlovac, Croatia, by their GPs. All patient records were analyzed according to the cause of CP, strongest pain a week before the examination, quality of sleep, and the Patients' Global Impression of Change scale. All statistical analyses were done using the IBM SPSS Statistics version 19.0.0.1 (www.spss.com). CP predominantly occurs in older age group. Patients with musculoskeletal pain accounted for the highest percentage (n = 316; 29%), followed by those with neuropathic pain (n = 253; 23.20%) and those with low back pain (n = 225; 20.60%). The mean pain intensity rating scale score was 8.3 ± 1.8 a week before the examination and the mean quality of sleep score was 6.8 ± 1.9. Moderate and severe sleep quality disorder was significantly present in patients over 65 years of age (p = 0.007), patients with musculoskeletal and neuropathic pain, back pain, and those having rated Patients' Global Impression of Change scale as worsening (p = 0.001). The severity of pain and poor quality of sleep are the leading causes of deterioration of the Patients' Global Impression of Change scale in patients suffering from musculoskeletal and neuropathic pain. In order to treat CP comprehensively, it is important for GPs to evaluate the outcomes of clinical treatment using tools for CP assessment. PMID:27276768

    Objectives This systematic review and meta-analysis examined the effects of psychological therapies for management of chronic pain in children. Methods Randomized controlled trials of psychological interventions treating children (<18 years) with chronic pain conditions including headache, abdominal, musculoskeletal, or neuropathic pain were searched for. Pain symptoms, disability, depression, anxiety, and sleep outcomes were extracted. Risk of bias was assessed and quality of the evidence was rated using GRADE. Results 35 included studies revealed that across all chronic pain conditions, psychological interventions reduced pain symptoms and disability posttreatment. Individual pain conditions were analyzed separately. Sleep outcomes were not reported in any trials. Optimal dose of treatment was explored. For headache pain, higher treatment dose led to greater reductions in pain. No effect of dosage was found for other chronic pain conditions. Conclusions Evidence for psychological therapies treating chronic pain is promising. Recommendations for clinical practice and research are presented. PMID:24602890

    2008-01-01

    Background Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error and ROM-variability. Methods Participants (n = 173) were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak) was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal), and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Results Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9° (95% CI; 12.2–15.6) for the WAD group, 17.9° (95% CI; 16.1–19.6) for the chronic neck pain group and 25.9° (95% CI; 23.7–28.1) for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Conclusion Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a history of neck trauma, nor

    2016-10-01

    In this article, the interrelatedness of age and chronic pain is discussed and testable hypotheses about this interrelationship are postulated. Numerous studies have consistently shown mild cognitive problems, together with changes in brain gray and white matter integrity, in chronic pain patients. More recently, a handful of studies have indicated that age may play a crucial role in the reduced neurocognitive integrity in these chronic pain patients. However, studies systematically examining this interrelationship are lacking. We now give several propositions of this interaction between age and chronic pain by summarizing the evidence for the following testable hypotheses: 1) neurocognitive deficits in chronic pain are age-dependent, 2) chronic pain induces early aging, or 3) chronic pain can be considered as an age accelerator, resulting in a disproportional decline in neurocognitive integrity with increasing age. To advance this important field, it is highly recommended that future studies systematically document cognitive and neuroanatomical changes in chronic pain patients as a function of age.

    This study aimed to analyze the experience of working women suffering from chronic musculoskeletal pain, using a qualitative design with a phenomenological approach. The technique drew on in-depth interviews with five working women that presented to the orthopedics and neurosurgery departments of a hospital in Guadalajara, Mexico, with a complaint of musculoskeletal pain for more than six months. The study showed that the women felt rejection, segregation, discrimination, lack of support at the workplace, and feelings of frustration and powerlessness related to their health condition. The women also perceived as a barrier the lack of efficiency in disability proceedings and job reintegration or relocation. Financial and family responsibilities were their main reason for continuing to work despite their chronic musculoskeletal pain. PMID:26735388

    1987-12-01

    The treatment approach presented in this article is an obvious departure from ways physicians are typically trained to handle patients' pain complaints. Traditional medical training focuses primarily on the management of acute pain. Unfortunately, the treatment modalities appropriate for acute pain are not applicable to most chronic pain disorders. Since physicians' practices contain many chronic pain patients, it is important for them to develop a more comprehensive and effective approach to the management of CLBP. Through the use of case vignettes, this article has attempted to elucidate some common problems experienced by patients with CLBP. It is a complex disorder that requires that the physicians be sensitive to the biologic, psychologic, and social aspects of the illness. Simply handing a patient with CLBP a set of back exercises or prescriptions for narcotics and sedatives will not be beneficial. Rather, the patient must be educated about the pain and taught to take an active role in his own treatment. By working with patients and their families, physicians can teach patients with CLBP the self-management skills essential for the resumption of a normal, productive life. PMID:2972043

    Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child’s pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child’s outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

    Holistic medicine seems to be efficient in the treatment of chronic pain in internal organs, especially when the pain has no known cause. It is quite surprising that while chronic pain can be one of the toughest challenges in the biomedical clinic, it is often one of the simplest things to alleviate in the holistic clinic. These pains are regarded as being caused by repressed emotions and are explained as psychosomatic reactions. Using holistic medicine, the patients can often be cured of their suffering when they assume responsibility for the repressed feelings. The holistic process theory of healing states that the return to the natural (pain free) state of being is possible whenever the person obtains the resources needed for existential healing. This shift is explained by the related quality of life and life mission theories. The resources needed are "holding" or genuine care in the dimensions of awareness, respect, care, acknowledgment, and acceptance with support and processing in the dimensions of feeling, understanding, and letting go of negative attitudes and beliefs. The preconditions for the holistic healing to take place are "love" and trust. Obtaining the full trust of the patient, therefore, seems to be the biggest challenge of holistic medicine, especially when dealing with a patient in pain.

    Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child's pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child's outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

  18. [Electrophysiological evaluation of pathophysiological and pharmacological characteristics of chronic pain].

    Recent studies have revealed considerable evidence for our understanding of the mechanisms underlying the development and maintenance of chronic pain including neuropathic and inflammatory pain. It is considered that plastic changes in the spinal dorsal horn contribute to the amplification of pain signaling. Moreover, persistent pain affects brain function and also the endogenous descending pain regulatory system. To characterize these pathophysiological changes and pharmacological properties in chronic pain conditions at the synaptic level, we have employed in vitro electrophysiology in slices of the spinal cord and supraspinal regions such as brainstem and hippocampus of adult mice and in vivo electrophysiology in anesthetized rats. In particular, we have successfully prepared spinal slices with an attached dorsal root, where A-fiber- or C-fiber-evoked monosynaptic excitatory postsynaptic currents or miniature excitatory postsynaptic currents were recorded from voltage-clamped dorsal horn neurons. In anesthetized rats, C-fiber-evoked field potentials were recorded from the spinal dorsal horn in response to electrical stimulation of the sciatic nerve fibers, and their long-term potentiation was elicited to mimic increased synaptic efficacy after peripheral nerve injury. Of interest is the finding that some drugs exerted the injury-specific effects on synaptic transmission, thus strongly suggesting the importance of pharmacological analysis at the synaptic level combined with electrophysiological techniques to obtain pathophysiological information and new insights into drug research in this field.

    Objective Chronic pain in individuals with HIV is a common, impairing condition. Behavioral interventions for chronic pain specifically tailored to this population have yet to be developed. We assert that understanding self-management strategies already used by persons living with these conditions is an essential first step, and is the objective of this investigation. Design We conducted a thematic analysis of qualitative data from 25 in-depth interviews with individuals with HIV and chronic pain. Results The primary pain self-management strategies articulated by participants were: physical activity; cognitive and spiritual strategies; spending time with family and friends and social support; avoidance of physical/social activity; medication-centric pain management; and substance use. Conclusions Some of these strategies may be viewed as beneficial and overlap with known HIV self-management strategies (cognitive strategies), whereas others may have negative health consequences (substance use). Interventions that incorporate healthy self-management strategies may be particularly effective in improving both HIV and pain outcomes. PMID:25645646

    This systematic review addresses the pathophysiology, diagnostic evaluation, and treatment of several chronic pain syndromes affecting the pelvic organs: chronic proctalgia, coccygodynia, pudendal neuralgia, and chronic pelvic pain. Chronic or recurrent pain in the anal canal, rectum, or other pelvic organs occurs in 7% to 24% of the population and is associated with impaired quality of life and high health care costs. However, these pain syndromes are poorly understood, with little research evidence available to guide their diagnosis and treatment. This situation appears to be changing: A recently published large randomized, controlled trial by our group comparing biofeedback, electrogalvanic stimulation, and massage for the treatment of chronic proctalgia has shown success rates of 85% for biofeedback when patients are selected based on physical examination evidence of tenderness in response to traction on the levator ani muscle-a physical sign suggestive of striated muscle tension. Excessive tension (spasm) in the striated muscles of the pelvic floor appears to be common to most of the pelvic pain syndromes. This suggests the possibility that similar approaches to diagnostic assessment and treatment may improve outcomes in other pelvic pain disorders. PMID:22110274

    Depression and chronic pain know no geographical boundaries. About 350 million people around the world experience long-lasting sadness and an unshakeable sense of hopelessness, and one person out of ten tries to live each day to its fullest despite continuous physical pain. These two difficult conditions frequently coexist, becoming more common with age. Looking ahead, we can expect the incidence of depression and chronic illness to grow, since more people over age 65 will populate the world by 2020 than children younger than five. PMID:25782107

    Objective Sleep disturbance in chronic pain is common, occurring in two-thirds of patients. There is a complex relationship between chronic pain and sleep; pain can disrupt sleep and poor sleep can exaggerate pain intensity. This may have an impact on both depressive symptoms and attention to pain. This study aims to evaluate the relationship between chronic pain and sleep, and the role of mood and attention. Methods Chronic pain patients, recruited from a secondary care outpatient clinic, completed self-report measures of pain, sleep, depressive symptoms and attention to pain. Hierarchical regression and structural equation modelling were used to explore the relationships between these measures. Participants (n = 221) were aged between 20 and 84 (mean = 52) years. Results The majority of participants were found to be ‘poor sleepers’ (86%) with increased pain severity, depressive symptoms and attention to pain. Both analytical approaches indicated that sleep disturbance is indirectly associated with increased pain severity Instead the relationship shared by sleep disturbance and pain severity was further associated with depressive symptoms and attention to pain. Conclusions Our results indicate that sleep disturbance may contribute to clinical pain severity indirectly though changes in mood and attention. Prospective studies exploring lagged associations between these constructs could have critical information relevant to the treatment of chronic pain. PMID:26726076

    The transition from acute pain to chronic pain entails considerable changes of patients at multiple levels of the nervous system and in psychological states. An accurate differentiation between acute and chronic pain is essential in pain management as it may help optimize analgesic treatments according to the pain state of patients. Given that acute and chronic pain could modulate brain states in different ways and that brain states could greatly shape the neural processing of external inputs, we hypothesized that acute and chronic pain would show differential effects on cortical responses to non-nociceptive sensory information. Here by analyzing auditory-evoked potentials (AEPs) to pure tones in rats with acute or chronic pain, we found opposite influences of acute and chronic pain on cortical responses to auditory inputs. In particular, compared to no-pain controls, the N100 wave of rat AEPs was significantly enhanced in rats with acute pain but significantly reduced in rats with chronic pain, indicating that acute pain facilitated cortical processing of auditory information while chronic pain exerted an inhibitory effect. These findings could be justified by the fact that individuals suffering from acute or chronic pain would have different vigilance states, i.e., the vigilance level to external sensory stimuli would be increased with acute pain, but decreased with chronic pain. Therefore, this auditory response holds promise of being a brain signature to differentiate acute and chronic pain. Instead of investigating the pain system per se, the study of pain-induced influences on cortical processing of non-nocicpetive sensory information might represent a potential strategy to monitor the progress of pain chronification in clinical applications.

    The purpose of this study was to determine veteran pain scale preference of four common pain scales: the Faces Scale, the Visual Analog Scale, the Numeric Rating Scale, and the Mankoski Pain Scale. The study also examined the reliability and validity of the Mankoski Pain Scale with the other three scales. A sample of veterans (N = 200) with chronic pain receiving treatment in a residential rehabilitation treatment program (RRTP) and a surgical and specialty care (SSC) outpatient clinic at a Department of Veterans Affairs (VA) medical center participated in the study. There was a significant difference between scales in regard to preference, χ2(3) = 64.59, p < .001. A large percentage of the sample preferred the Mankoski Pain Scale (46%). Test-retest of the reliability was comparable for all the scales. Validity of the Mankoski scale was excellent, as it correlated very well with the Numeric (r = .84, p < .001), Analog (r = .83, p < .001), and Faces (r = .78, p < .001) scales. The findings indicate that the Mankoski Pain Scale is a valid and reliable tool for pain with veterans, and it was the preferred scale by veterans for use when describing pain.

    Chronic pancreatitis (CP) is a chronic inflammation of pancreas that leads to progressive fibrosis of pancreatic parenchyma. Commonest indication of surgery in chronic pancreatitis is intractable pain. Choice of procedure depends upon the main pancreatic duct (MPD) morphology. Decompression is useful in dilated and obstructed ducts. Traditional form of decompression is construction of a pancreatico-jejunal anastomosis (LPJ). Another method to achieve ductal decompression is by a pancreaticogastrostomy (LPG) and this study will try to evaluate its effectiveness against pancreaticojejunostomy. To compare the effectiveness of LPG and LPJ in relieving intractable abdominal pain in patients with CP and their respective post-operative complications. This prospective study was done over a period of 4 years from Jan 2007 to Dec 2010 at IPGME & R (SSKM), a tertiary hospital of eastern India. Patients with diagnosis of CP with or without duct calculi and MPD diameter ≥7 mm with intractable pain were included. 70 patients were randomly allocated for LPJ and LPG operation by lottery method. Study tools were questionnaires, blood and radiological investigations and standard instruments for open surgery. The patients were prospectively analyzed for duration of surgery and hospital stay, operative/postoperative complications and assessment of postoperative pain relief. Pain relief was assessed as complete (no analgesic requirement), satisfactory (tolerable pain with normal daily activities) and unsatisfactory (hospitalization, narcotics or hampered daily activities). 1. Operative time was shorter in LPG than LPJ (Median 85 vs. 110 min). 2. Incidence of ileus was lesser in LPG group (p = .054). Other complications were comparable in both groups. 3. LPG was associated with shorter duration of hospital stay (Mean 6 vs. 8 days). 4. Pain relief was comparable in LPG and LPJ. LPG is a good alternative to LPJ for CP. PMID:26139966

    OBJECTIVES: to measure the pain intensity, identify the disability and depression levels in people with chronic back pain and to correlate these variables. A cross-sectional, descriptive and exploratory study was undertaken at the Pain Treatment Clinic of the University of São Paulo at Ribeirão Preto Hospital das Clínicas, between February and June 2012, after receiving approval from the Ethics Committee at the University of São Paulo at Ribeirão Preto College of Nursing. METHOD: sixty subjects with chronic back pain participated. The instruments used were: the 11-point Numerical Category Scale, the Roland-Morris Disability Questionnaire and the Beck Depression Inventory. To analyze the data, the arithmetic means, standard deviations and Spearman's correlation coefficient were calculated. RESULTS: the findings show that the participants presented high pain, disability and depression levels. The correlation between pain intensity and disability and between pain intensity and depression was positive and weak and, between disability and depression, positive and moderate. CONCLUSION: the study variables showed moderate and weak indices and the mutual correlations were positive. PMID:25296139

    Central sensitivity syndromes (CSS) include fibromyalgia syndrome (FMS), irritable bowel syndrome, temporomandibular disorder, restless legs syndrome, chronic fatigue syndrome, and other similar chronic painful conditions that are based on central sensitization (CS). CSS are mutually associated. In this paper, prevalence of FMS among other members of CSS has been described. An important recent recognition is an increased prevalence of FMS in other chronic pain conditions with structural pathology, for example, rheumatoid arthritis, systemic lupus, ankylosing spondylitis, osteoarthritis, diabetes mellitus, and inflammatory bowel disease. Diagnosis and proper management of FMS among these diseases are of crucial importance so that unwarranted use of such medications as corticosteroids can be avoided, since FMS often occurs when RA or SLE is relatively mild.

    Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.

    Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (ie, chronic postsurgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (ie, surgery, viral infection, injury, and toxic or noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

    Background The 9-item STarT-Back screening tool was developed in primary care patients with low back pain (LBP) to identify those at greatest risk for chronic pain and requiring targeted treatment. We conducted a secondary data analysis study to examine the performance of comparable questionnaire items in a sample of primary care patients with well-defined acute LBP. Methods In a prospective cohort study, 605 primary care patients with LBP of less than 30 days answered a questionnaire with 6 items identical and 3 items analogous to the 9-item STarT-Back. Participants were followed up at 6 months and 2 years. STarT-Back rules were applied to classify participant's risk of chronic LBP, and the performance of the screening items in predicting outcomes was assessed using likelihood ratios. Results The proportion of patients with chronic pain at follow-up was considerably lower (6 months: 22%; 2 years: 25%) than in the STarT-Back validation cohort (40%) of patients with pain of any duration. The probability of developing chronic pain given a high-risk designation by items similar to the STarT-Back increased the pre-test probability to 31% and 35%. Likelihood ratios were close to 1. Conclusions A risk classification schema using the recommended cut-off scores with items similar to the STarT-Back in a primary care population with strictly defined acute LBP had limited ability to identify persons who progressed to chronic pain. The results suggest caution when applying the STarT-Back in patients with acute LBP and a need to consider a modification of its cut-offs. PMID:25381748

    Chronic whiplash is a debilitating condition characterized by increased sensitivity to painful stimuli, maladaptive illness beliefs, inappropriate attitudes, and movement dysfunctions. Previous work in people with chronic low back pain and chronic fatigue syndrome indicates that pain neurophysiology education is able to improve illness beliefs and attitudes as well as movement performance. This single-case study (A-B-C design) with six patients with chronic whiplash associated disorders (WAD) was aimed at examining whether education about the neurophysiology of pain is accompanied by changes in symptoms, daily functioning, pain beliefs, and behavior. Periods A and C represented assessment periods, while period B consisted of the intervention (pain neurophysiology education). Results showed a significant decrease in kinesiophobia (Tampa Scale for Kinesiophobia), the passive coping strategy of resting (Pain Coping Inventory), self-rated disability (Neck Disability Index), and photophobia (WAD Symptom List). At the same time, significantly increased pain pressure thresholds and improved pain-free movement performance (visual analog scale on Neck Extension Test and Brachial Plexus Provocation Test) were established. Although the current results need to be verified in a randomized, controlled trial, they suggest that education about the physiology of pain is able to increase pain thresholds and improve pain behavior and pain-free movement performance in patients with chronic WAD.

    The history of physical and sexual abuse in childhood and adulthood was assessed in 31 women with chronic pelvic pain, 142 women with chronic pain in other locations, and 32 controls. Thirty-nine percent of patients with chronic pelvic pain had been physically abused in childhood. This percentage was significantly greater than that observed in other chronic-pain patients (18.4%) or controls (9.4%), though the prevalence of childhood sexual abuse did not differ among the groups (19.4, 16.3, and 12.5%, respectively). Abuse in adulthood was less common and was not significantly more likely to have occurred in patients with chronic pelvic pain than in other chronic-pain patients or controls. These data suggest that pelvic pain is unlikely to be specifically and psychodynamically related to sexual abuse but that the pernicious nature of abuse, whether physical or sexual, may promote the chronicity of painful conditions.

    This study explored family relationships and intimacy of women experiencing chronic pain from the perspective of the women and their family members. A narrative ethnographic qualitative research design was used. Narrative and field data were analyzed using the coding procedure outlined by Strauss aided by the QSR NUD*IST 4 qualitative computer software program. Twenty-five women self-identified as experiencing chronic pain, and 13 family members including 7 husbands, 1 father, 1 stepmother, and 4 children living in the home were interviewed. Three patterns of behavior emerged regarding family relationships: cycle of close involvement compensated with isolation, focus directed toward others, and loss of physical sexual intimacy. Findings of this study indicate that family members' perception is that chronic pain affects important basic relationships and both emotional and physical intimacy. A need exists to relieve some of the suffering that accompanies pain in these women and their families. Based on the study's findings, several treatment strategies are recommended. PMID:14566711

    Background: Despite tobacco farming involving intensive manual labor, chronic low back pain (CLBP) prevalence and associated factors are unknown among this occupational group. Methods: This was a cross-sectional study conducted in southern Brazil. A random sample of tobacco farmers was interviewed. Socioeconomic and individual characteristics, occupational tasks, workloads, and comorbidities were investigated. Chronic low back pain prevalence was described in relation to independent variables, and associations were examined with Poisson regression. Results: Chronic low back pain prevalence was 8·4%. Increasing age, rearing two or more species of livestock (PR 1·65), exposure to tasks that require heavy physical exertion (PR 2·00), working in awkward postures (PR 1·36), green tobacco sickness (GTS) (PR 1·63), pesticide poisoning (PR 2·37), and minor psychiatric disorders (PR 2·55) were associated with CLBP. Conclusions: This study found that CLBP is a relevant health problem among tobacco farmers and highlights understudied risk factors such as pesticide poisoning and GTS. Policies to minimize exposure to physiological and chemical workloads in tobacco planting to prevent CLBP are needed. Health professionals should be trained to diagnose and prevent acute low back pain episodes and thus prevent/minimize limitations and disabilities due to CLBP. PMID:25633930

    The aim of this study was to investigate the effectiveness of balneotherapy (BT), which is applied in addition to physical therapy (PT), in the treatment of chronic neck pain. Sixty patients with chronic neck pain were divided into study (n = 30) and control (n = 30) groups. All of the patients in both groups were treated with a 15-session standard PT program consisting of hot pack, ultrasound, and transcutaneous electrical stimulation. Patients in the study group were also treated with a 15-session BT program lasting 20 min/day in addition to the standard PT program. Visual analogue scale (VAS), modified neck disability index (mNDI), and Nottingham Health Profile (NHP) scores of all patients were evaluated at three different times as pretreatment, posttreatment, and posttreatment third week. There was no statistically significant difference between the clinical and demographic characteristics of the patients in different groups before treatment. Intragroup analysis revealed significant improvement in all parameters for both of the groups at all time intervals. Intergroup analysis uncovered the superiority of the study group. According to the results of this study, BT in combination with PT is superior to PT alone in reducing pain and disability and improving quality of life in patients with chronic neck pain.

    Touch plays a significant role in human social behavior and social communication, and its rewarding nature has been suggested to involve opioids. Opioid blockade in monkeys leads to increased solicitation and receipt of grooming, suggesting heightened enjoyment of touch. We sought to study the role of endogenous opioids in perception of affective touch in healthy adults and in patients with fibromyalgia, a chronic pain condition shown to involve reduced opioid receptor availability. The pleasantness of touch has been linked to the activation of C-tactile fibers, which respond maximally to slow gentle touch and correlate with ratings of pleasantness. We administered naloxone to patients and healthy controls to directly observe the consequences of µ-opioid blockade on the perceived pleasantness and intensity of touch. We found that at baseline chronic pain patients showed a blunted distinction between slow and fast brushing for both intensity and pleasantness, suggesting reduced C-tactile touch processing. In addition, we found a differential effect of opioid blockade on touch perception in healthy subjects and pain patients. In healthy individuals, opioid blockade showed a trend toward increased ratings of touch pleasantness, while in chronic pain patients it significantly decreased ratings of touch intensity. Further, in healthy individuals, naloxone-induced increase in touch pleasantness was associated with naloxone-induced decreased preference for slow touch, suggesting a possible effect of opioid levels on processing of C-tactile fiber input. These findings suggest a role for endogenous opioids in touch processing, and provide further evidence for altered opioid functioning in chronic pain patients. PMID:27022625

    Spinal cord stimulation (SCS) applications and technologies are fast advancing. New SCS technologies are being used increasingly in the clinical environment, but often there is a lag period between the clinical application and the publishing of high-quality evidence on safety and efficacy. Recent developments will undoubtedly expand the applicability of SCS, allowing more effective and individualized treatment for patients, and may have the potential to salvage patients who have previously failed neuromodulation. Already, high-level evidence exists for the safety, efficacy, and cost-effectiveness (Level I–II) of traditional SCS therapies in the treatment of chronic refractory low back with predominant limb pain (regardless of surgical history). More than half of all patients with chronic painful conditions experience sustained and significant levels of pain reduction following SCS treatment. Although only limited evidence exists for burst stimulation, there is now Level I evidence for both dorsal root ganglion SCS and high-frequency SCS that demonstrates compelling results compared with traditional therapies. The body of evidence built on traditional SCS research may be redundant, with newer iterations of SCS therapies such as dorsal root ganglion SCS, high-frequency SCS, and burst SCS. A number of variables have been identified that can affect SCS efficacy: implanter experience, appropriate patient selection, etiologies of patient pain, existence of comorbidities, including psychiatric illness, smoking status, and delay to SCS implant following pain onset. Overall, scientific literature demonstrates SCS to be a safe, effective, and drug-free treatment option for many chronic pain etiologies. PMID:27445503

    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). Four studies (188 participants) reporting outcomes equivalent to 50% pain reduction or more

    Objective To evaluate sensitization, myofascial trigger points, and quality of life in women with chronic pelvic pain with and without endometriosis. Methods A cross-sectional prospective study of women aged 18 to 50 with pain suggestive of endometriosis and healthy, pain-free volunteers without history of endometriosis. Patients underwent a physiatric neuro-musculoskeletal assessment of clinical signs of sensitization and myofascial trigger points in the abdominopelvic region. Pain symptoms, psychosocial, and quality-of-life measures were also assessed. All pain participants underwent laparoscopic excision of suspicious lesions to confirm endometriosis diagnosis by histologic evaluation. Results Patients included 18 with current, biopsy-proven endometriosis, 11 with pain only, and 20 healthy volunteers. The prevalence of sensitization as measured by regional allodynia and hyperalgesia was similar in both pain groups (83% and 82%) but much lower among healthy volunteers (15%, p<0.001). Nearly all women with pain had myofascial trigger points (94% and 91%). Adjusting for study group, those with high anxiety (OR=1.05, 95% CI:1.004–1.099; p=0.031) and depression (OR=1.06, 95% CI:1.005–1.113; p=0.032) scores were more likely to have sensitization. Pain patients with any history of endometriosis had the highest proportion of sensitization compared to the others (87% v 67% v 15%; p<0.001). Adjusting for any history of endometriosis, those with myofascial trigger points were most likely sensitized (OR=9.41, 95% CI:1.77–50.08, p=0.009). Conclusions Sensitization and myofascial trigger points were common in women with pain regardless of whether they had endometriosis at surgery. Those with any history of endometriosis were most likely to have sensitization. Traditional methods of classifying endometriosis-associated pain based on disease, duration, and anatomy are inadequate and should be replaced by a mechanism-based evaluation, as our study illustrates.

    Chronic pelvic pain is common, but rarely cured, thus patients seek both second opinions and alternative means of controlling their pain. Complementary and alternative medicine accounts for 11.2% of out-of-pocket medical expenditures for adults for all conditions in the United States. Although there are many treatments, rigorous testing and well-done randomized studies are lacking. Dietary changes and physical modalities such as physical therapy have often been included in the category of alternative medicine, but their use is now considered mainstream. This article concentrates on other sources of alternative and complementary medicine, such as dietary supplementation and acupuncture.

    Neuromodulation techniques modify the activity of the central or peripheral nervous system. Spinal cord stimulation is a reversible and minimally invasive treatment whose efficacy and cost effectiveness are recognized for the treatment of chronic neuropathic pain or ischemic pain. Spinal cord stimulation is not the option of last resort and should be considered among other options before prescribing long-term opioids or considering reoperation. The selection and regular follow-up of patients are crucial to the success of the therapy. PMID:27506068

    Acceptance of chronic pain has increasingly become a significant issue in the field of pain management. Many researchers have suggested that patients with better acceptance of pain are more likely to have better functioning both in physical and psychological status. In many countries, the Chronic Pain Acceptance Questionnaire (CPAQ) and CPAQ-8 have been validated and utilized frequently to measure the pain acceptance of patients with chronic pain. However, the CPAQ and CPAQ-8 yet have not been introduced and validated in Mainland China.In this study, we aimed to translate the English version of the CPAQ into simplified Chinese, make proper cross-cultural adaptations, and validate the psychometric properties of the Chinese version of the CPAQ and the CPAQ-8.The English version of the CPAQ was first linguistically translated and cross-culturally adapted to formulate a Chinese version. Then, we recruited 224 patients from a pain clinic and every participant was asked to finish a series of questionnaires. Finally, statistical analysis was performed to test the psychometric properties of the CPAQ and the CPAQ-8.Both confirmatory factor analysis (CFA) and principal component analysis (PCA) confirmed a 2-factor structure for the CPAQ and the CPAQ-8. Nine out of 10 of the hypotheses were validated for construct validity. The overall intraclass correlation coefficient (ICC) value for the CPAQ and CPAQ-8 were 0.92 and 0.89, respectively. In addition, the Cronbach α values for both the CPAQ and the CPAQ-8 showed excellent test-retest reliability.In conclusion, the original CPAQ was successfully developed into the Chinese version of the CPAQ and CPAQ-8 with excellent validity and reliability. The scores of the CPAQ or CPAQ-8 might be a strong predictor for the physical and psychological function of chronic pain patients. In addition, to improve the satisfaction of surgery patients, we recommend measuring patients' pain acceptance using the CPAQ or CPAQ-8 before and after the

    Background Rubefacients (containing salicylates or nicotinamides) cause irritation of the skin, and are believed to relieve various musculoskeletal pains. They are available on prescription, and are common components in over-the-counter remedies. A non-Cochrane review in 2004 found limited evidence for efficacy. Objectives To review current evidence for efficacy and safety of topically applied rubefacients in acute and chronic painful musculoskeletal conditions in adults. Search methods Cochrane CENTRAL, MEDLINE, EMBASE, the Oxford Pain Relief Database, and reference lists of articles were searched; last search December 2008. Selection criteria Randomised, double blind, placebo or active controlled clinical trials of topical rubefacient for musculoskeletal pain in adults, with at least 10 participants per treatment arm, and reporting outcomes at close to 7 (minimum 3, maximum 10) days for acute conditions and 14 (minimum 7) days or longer for chronic conditions. Data collection and analysis Two review authors independently assessed trials for inclusion and quality, and extracted data. Relative benefit or risk and number needed to treat to benefit or harm (NNT or NNH) were calculated with 95% confidence intervals (CI). Acute and chronic conditions were analysed separately. Main results Six placebo and one active controlled studies (560 and 137 participants) in acute pain, and seven placebo and two active controlled studies (489 and 90 participants) in chronic pain were included. All used topical salicylates. The evidence in acute conditions was not robust; using only better quality, valid studies, there was no difference between topical rubefacient and topical control, though overall, including lower quality studies, the NNT for clinical success compared with placebo was 3.2 (95% CI: 2.4 to 4.9). In chronic conditions the NNT was 6.2 (95% CI: 4.0 to 13) compared with topical placebo. Adverse events and withdrawals occurred more often with rubefacients than placebo

    As in the general population, chronic pain is a prevalent and burdensome affliction in active-duty military personnel. Painful conditions in military members can be categorized broadly in terms of whether they arise directly from combat injuries (gunshot, fragmentation wound, blast impact) or whether they result from non-combat injuries (sprains, herniated discs, motor vehicle accidents). Both combat-related and non-combat-related causes of pain can further be classified as either acute or chronic. Here we discuss the state of pain management as it relates to the military population in both deployed and non-deployed settings. The term non-battle injury (NBI) is commonly used to refer to those conditions not directly associated with the combat actions of war. In the history of warfare, NBI have far outstripped battle-related injuries in terms not only of morbidity, but also mortality. It was not until improvements in health care and field medicine were applied in World War I that battle-related deaths finally outnumbered those attributed to disease and pestilence. However, NBI have been the leading cause of morbidity and hospital admission in every major conflict since the Korean War. Pain remains a leading cause of presentation to military medical facilities, both in and out of theater. The absence of pain services is associated with a low return-to-duty rate among the deployed population. The most common pain complaints involve the low-back and neck, and studies have suggested that earlier treatment is associated with more significant improvement and a higher return to duty rate. It is recognized that military medicine is often at the forefront of medical innovation, and that many fields of medicine have reaped benefit from the conduct of war.

    Attentional biases to painful stimuli are evident in individuals with chronic pain, although the directional tendency of these biases (ie, toward or away from threat-related stimuli) remains unclear. This study used eye-tracking technology, a measure of visual attention, to evaluate the attentional patterns of individuals with and without chronic pain during exposure to injury-related and neutral pictures. Individuals with (N=51) and without chronic pain (N=62) completed a dot-probe task using injury-related and neutral pictures while their eye movements were recorded. Mixed-design analysis of variance evaluated the interaction between group (chronic pain, pain-free) and picture type (injury-related, neutral). Reaction time results showed that regardless of chronic pain status, participants responded faster to trials with neutral stimuli in comparison to trials that included injury-related pictures. Eye-tracking measures showed within-group differences whereby injury-related pictures received more frequent fixations and visits, as well as longer average visit durations. Between-group differences showed that individuals with chronic pain had fewer fixations and shorter average visit durations for all stimuli. An examination of how biases change over the time-course of stimulus presentation showed that during the late phase of attention, individuals with chronic pain had longer average gaze durations on injury pictures relative to pain-free individuals. The results show the advantage of incorporating eye-tracking methodology when examining attentional biases, and suggest future avenues of research. PMID:27570461

There are distinct groups with increased vulnerability for the emergence of chronic pain. These groups may be defined by developmental status and/or life circumstances. Within the pediatric, geriatric, and drug abuser populations, chronic pain represents a significant health issue. This article focuses on known anatomic, physiologic, and genetic mechanisms underlying chronic pain in these populations, and highlights the need for a multimodal approach from multiple health care professionals for management of chronic pain in those with the most risk.

    Many cortical areas play crucial roles in higher order brain functions such as pain and emotion-processing, decision-making, and cognition. Among them, anterior cingulate cortex (ACC) and insular cortex (IC) are two key areas. Glutamate mediates major excitatory transmission during long-term plasticity in both physiological and pathological conditions. Specifically related to nociceptive or pain behaviors, metabotropic glutamate subtype receptors (mGluRs) have been involved in different types of synaptic modulation and plasticity from periphery to the spinal cord. However, less is known about their functional roles in plasticity related to pain and its related behaviors within cortical regions. In this review, we first summarized previous studies of synaptic plasticity in both the ACC and IC, and discussed how mGluRs may be involved in both cortical long-term potentiation (LTP) and long-term depression (LTD)-especially in LTD. The activation of mGluRs contributes to the induction of LTD in both ACC and IC areas. The loss of LTD caused by peripheral amputation or nerve injury can be rescued by priming ACC or IC with activations of mGluR1 receptors. We also discussed the potential functional roles of mGluRs for pain-related behaviors. We propose that targeting mGluRs in the cortical areas including the ACC and IC may provide a new therapeutic strategy for the treatment of chronic pain, phantom pain or anxiety. PMID:27296638

    We report reversal of chronic postsurgical pain (CPSP) along with functional restoration after total knee replacement (TKR) in two patients, using a combination therapy that included ultrasonography-guided pulsed radiofrequency (PRF) of nerves supplying the knee to provide pain relief, along with dry needling (DN) to relax myofascial triggers/bands that caused painful stiffness and restricted movement of muscles acting across the knee. Both patients showed demonstrable pain relief, as evidenced by changes in pain as assessed on the Numeric Rating Scale (patient 1: 4-9/10 [pre-treatment] to 0-3/10 [6 months post-treatment]; patient 2: 5-9/10 to 0-4/10), Oxford Knee Score (patient 1: 17 to 40; patient 2: 12 to 39), Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs score (patient 1: 16 to 0; patient 2: 18 to 0), and Patient Health Questionnaire-9 score (patient 1: 17 to 2; patient 2: 20 to 2). The selection of the PRF-and-DN combination for treating post-TKR CPSP was based on a new idea that CPSP is a neuromyopathic phenomenon involving both sensory and motor neuropathy. It has evolved from our experience of 8 years. Physiotherapy worked synergistically with DN, optimizing muscle performance and pain relief.

    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

    Background Dexketoprofen, an NSAID used in the management of acute and chronic pains, is licensed in several countries but has not previously been the subjected of a systematic review. We used published and unpublished information from randomised clinical trials (RCTs) of dexketoprofen in painful conditions to assess evidence on efficacy and harm. Methods PubMed and Cochrane Central were searched for RCTs of dexketoprofen for pain of any aetiology. Reference lists of retrieved articles and reviews were also searched. Menarini Group produced copies of published and unpublished studies (clinical trial reports). Data were abstracted into a standard form. For studies reporting results of single dose administration, the number of patients with at least 50% pain relief was derived and used to calculate the relative benefit (RB) and number-needed-to-treat (NNT) for one patient to achieve at least 50% pain relief compared with placebo. Results Thirty-five trials were found in acute pain and chronic pain; 6,380 patients were included, 3,381 receiving dexketoprofen. Information from 16 trials (almost half the total patients) was obtained from clinical trial reports from previously unpublished trials or abstracts. Almost all of the trials were of short duration in acute conditions or recent onset pain. All 12 randomised trials that compared dexketoprofen (any dose) with placebo found dexketoprofen to be statistically superior. Five trials in postoperative pain yielded NNTs for 12.5 mg dexketoprofen of 3.5 (2.7 to 4.9), 25 mg dexketoprofen of 3.0 (2.4 to 3.9), and 50 mg dexketoprofen of 2.1 (1.5 to 3.5). In 29/30 active comparator trials, dexketoprofen at the dose used was at least equivalent in efficacy to comparator drugs. Adverse event withdrawal rates were low in postoperative pain and somewhat higher in trials of longer duration; no serious adverse events were reported. Conclusion Dexketoprofen was at least as effective as other NSAIDs and paracetamol/opioid combinations

    Low Back Pain (LBP) is a major medical and socio-economical problem in the industrialized countries. Exercise therapy is the keystone of conservative treatment for chronic low back pain (CLBP). Numerous randomized trials and clinical practice guidelines have supported that exercise diminishes disability and pain severity while improving fitness and occupational status in patients with CLBP, as well as decrease its recurrence rate. However, there is no significant evidence that one particular type of exercise is clearly more effective than others. Here we present a descriptive review of different types of exercise for therapeutic or prevention purposes in patients with CLBP. Studies suggest that individually tailored, supervised exercise programs are associated with the best outcomes. High quality clinical trials are needed to determine the effectiveness of specific interventions (type, time, intensity and other characteristics) aimed at individuals and/or specific target groups.

    Researchers have become increasingly interested in the social context of chronic pain conditions. The purpose of this article is to provide an integrated review of the evidence linking marital functioning with chronic pain outcomes including pain severity, physical disability, pain behaviors, and psychological distress. We first present an overview of existing models that identify an association between marital functioning and pain variables. We then review the empirical evidence for a relationship between pain variables and several marital functioning variables including marital satisfaction, spousal support, spouse responses to pain, and marital interaction. On the basis of the evidence, we present a working model of marital and pain variables, identify gaps in the literature, and offer recommendations for research and clinical work. Perspective The authors provide a comprehensive review of the relationships between marital functioning and chronic pain variables to advance future research and help treatment providers understand marital processes in chronic pain.

    Pain catastrophizing is becoming increasingly recognized as a clinically important psychological factor in chronic musculoskeletal pain. In this retrospective cross-sectional study, we have identified factors associated with an increased risk for pain catastrophizing in chronic neck pain (CNP) patients. We obtained data from our medical database on 331 patients who were treated for neck pain as their chief complaint at our clinic. The Pain Catastrophizing Scale (PCS) was used to define a high pain catastrophizing state (PCS score ≥21) in this study. Patient demographics, pain-related factors, and psychological factors were evaluated with logistic regression analysis to identify risk factors of high pain catastrophizing among patients with CNP. A total of 256 patients with CNP satisfied the study inclusion criteria and were included in the analyses. The median PCS score was 16 (range, 0-45), and 86 of 256 patients (33.5%) reported a PCS score ≥21. In multivariate analysis, high pain intensity, clinical insomnia, and a high level of depression/anxiety were strongly associated with high pain catastrophizing in patients with CNP. Depression was the strongest predictor of high pain catastrophizing, with an odds ratio of 7.35 (95% confidence interval 2.23-24.22). High pain catastrophizing was not significantly related to age, gender, comorbidities, or neck pain-related physical symptoms. In conclusion, poor psychological states should be addressed as an important part of pain management in CNP patients who are susceptible to high pain catastrophizing. PMID:27631217

    Aberrant neuronal activity in injured peripheral nerves is believed to be an important factor in the development of neuropathic pain (NPP). Channel protein pCREB of that activity has been shown to mitigate the onset of associated molecular events in the nervous system, and sodium hydrosulfide (NaHS) could inhibit the expression of pCREB. However, whether NaHS could relieve the pain, it needs further experimental research. Furthermore, the clinical potential that NaHS was used to relieve pain was limited so it would be required. To address these issues, the rats of sciatic nerve chronic constriction injury (CCI) were given intraperitoneal injection of NaHS containing hydrogen sulfide (H2S). The experimental results showed that NaHS inhibited the reduction of paw withdrawal thermal latency (PWTL), mechanical withdrawal threshold (MWT), and the level of pCREB in CCI rats in a dose-dependent manner and they were greatly decreased in NaHSM group (P < 0.05). NaHS alleviates chronic neuropathic pain by inhibiting expression of pCREB in the spinal cord of Sprague-Dawley rats. PMID:25506383

    The use of interventions based on the best available evidence in occupational therapy is essential, and evaluation of research is part of an evidence-based practice. The aim of this study was to assess the quality of studies describing and evaluating the effects of occupational therapy interventions on chronic pain. A systematic review of studies with diverse designs was carried out. A quality assessment was conducted, and the level of evidence was defined using the Research Pyramid Model. Of 19 included studies, three received the highest evidence level, and three were considered to be of high quality. The clinical recommendations that can be derived from this study are the following: occupational therapy interventions should start from the identified needs of the person with chronic pain; no support exists for the effectiveness of electromyographic biofeedback training as a supplement, more studies are needed to confirm this result; the efficacy of instructions on body mechanics was significant during work-hardening treatment; and occupational therapists need to perform and present more clinical studies of high quality and high-evidence level to build up a trustworthy arsenal of evidence-based interventions, for example, in persons with chronic pain.

    Purpose Although chronic prostatitis/chronic pelvic pain syndrome is a prevalent urological disorder among men of all ages, its etiology remains unknown. Only a few previous studies have examined associations between lifestyle factors and chronic prostatitis/chronic pelvic pain syndrome, of which most were limited by the cross-sectional study design and lack of control for possible confounders. To address these limitations we performed a cohort study of major lifestyle factors (obesity, smoking and hypertension) and chronic prostatitis/chronic pelvic pain syndrome risk in the HPFS (Health Professionals Follow-up Study), a large ongoing cohort of United States based male health professionals. Materials and Methods The HPFS includes 51,529 men who were 40 to 75 years old at baseline in 1986. At enrollment and every 2 years thereafter participants have completed questionnaires on lifestyle and health conditions. In 2008 participants completed an additional set of questions on recent chronic prostatitis/chronic pelvic pain syndrome pain symptoms modified from the NIH (National Institutes of Health)-CPSI (Chronic Prostatitis Symptom Index) as well as questions on approximate date of symptom onset. The 653 participants with NIH-CPSI pain scores 8 or greater who first experienced symptoms after 1986 were considered incident chronic prostatitis/chronic pelvic pain syndrome cases and the 19,138 who completed chronic prostatitis/chronic pelvic pain syndrome questions but did not report chronic prostatitis/chronic pelvic pain syndrome related pain were considered noncases. Results No associations were observed for baseline body mass index, waist circumference, waist-to-hip ratio, cigarette smoking and hypertension with chronic prostatitis/chronic pelvic pain syndrome risk (each OR ≤1.34). Conclusions In this large cohort study none of the lifestyle factors examined was associated with chronic prostatitis/chronic pelvic pain syndrome risk. As the etiology of chronic

    Fibromyalgia and widespread pain were common in Gulf War veterans with unexplained illness referred to a rheumatology clinic. Increased tenderness was demonstrated in the postmenstrual phase of the cycle compared with the intermenstrual phase in normally cycling women but not in users of oral contraceptives. Patients with fibromyalgia had high levels of symptoms that have been used to define silicone implant-associated syndrome. Tender points were found to be a common transient finding associated with acute infectious mononucleosis, but fibromyalgia was an unusual long-term outcome. The common association of fibromyalgia with other rheumatic and systemic illnesses was further explored. A preliminary study revealed a possible linkage of fibromyalgia to the HLA region. Patients with fibromyalgia were found to have an impaired ability to activate the hypothalamic pituitary portion of the hypothalamic pituitary adrenal axis as well as the sympathoadrenal system, leading to reduced corticotropin and epinephrine response to hypoglycemia. Much interest has been expressed in the literature on the possible role of autonomic dysfunction in the development or exacerbation of fatigue and other symptoms in chronic fatigue syndrome. Mycoplasma genus and mycoplasma fermentans were detected by polymerase chain reaction in patients with chronic fatigue syndrome. It was reported that myofascial temporomandibular disorder does not run in families. No major therapeutic trials in fibromyalgia, chronic fatigue syndrome, or myofascial pain syndrome were reported over the past year. The effectiveness of cognitive behavioral therapy and behavior therapy for chronic pain in adults was emphasized. A favorable outcome of fibromyalgia and chronic fatigue syndrome in children and adolescents was reported.

  12. Demonstration of Cutaneous Allodynia in Association with Chronic Pelvic Pain

    2009-01-01

    Pelvic pain is a common condition that is associated with dysmenorrhea and endometriosis. In some women the severe episodes of cyclic pain change and the resultant pain becomes continuous and this condition becomes known as Chronic Pelvic Pain. This state can be present even after the appropriate medical or surgical therapy has been instituted. It can be associated with pain and tenderness in the muscles of the abdomen wall and intra-pelvic muscles leading to severe dyspareunia. Additional symptoms of irritable bowel and interstitial cystitis are common. A common sign of the development of this state is the emergence of cutaneous allodynia which emerges from the so-called viscero-somatic reflex. A simple bedside test for the presence of cutaneous allodynia is presented that does not require excessive time or special equipment. This test builds on previous work associated with changes in sensation related to gall bladder function and the viscera-somatic reflex(1;2). The test is undertaken with the subject s permission after an explanation of how the test will be performed. Allodynia refers to a condition in which a stimulus that is not normally painful is interpreted by the subject as painful. In this instance the light touch associated with a cotton-tipped applicator would not be expected to be painful. A positive test is however noted by the woman as suddenly painful or suddenly sharp. The patterns of this sensation are usually in a discrete pattern of a dermatome of the nerves that innervate the pelvis. The underlying pathology is now interpreted as evidence of neuroplasticity as a consequence of severe and repeating pain with changes in the functions of the dorsal horns of the spinal cord that results in altered function of visceral tissues and resultant somatic symptoms(3). The importance of recognizing the condition lies in an awareness that this process may present coincidentally with the initiating condition or after it has been treated. It also permits the

    OBJECTIVE The aim of this study was to systematically review dextrose (d-glucose) prolotherapy efficacy in the treatment of chronic musculoskeletal pain. DATA SOURCES Electronic databases PubMed, Healthline, OmniMedicalSearch, Medscape, and EMBASE were searched from 1990 to January 2016. STUDY SELECTION Prospectively designed studies that used dextrose as the sole active prolotherapy constituent were selected. DATA EXTRACTION Two independent reviewers rated studies for quality of evidence using the Physiotherapy Evidence Database assessment scale for randomized controlled trials (RCTs) and the Downs and Black evaluation tool for non-RCTs, for level of evidence using a modified Sackett scale, and for clinically relevant pain score difference using minimal clinically important change criteria. Study population, methods, and results data were extracted and tabulated. DATA SYNTHESIS Fourteen RCTs, 1 case–control study, and 18 case series studies met the inclusion criteria and were evaluated. Pain conditions were clustered into tendinopathies, osteoarthritis (OA), spinal/pelvic, and myofascial pain. The RCTs were high-quality Level 1 evidence (Physiotherapy Evidence Database ≥8) and found dextrose injection superior to controls in Osgood–Schlatter disease, lateral epicondylitis of the elbow, traumatic rotator cuff injury, knee OA, finger OA, and myofascial pain; in biomechanical but not subjective measures in temporal mandibular joint; and comparable in a short-term RCT but superior in a long-term RCT in low back pain. Many observational studies were of high quality and reported consistent positive evidence in multiple studies of tendinopathies, knee OA, sacroiliac pain, and iliac crest pain that received RCT confirmation in separate studies. Eighteen studies combined patient self-rating (subjective) with psychometric, imaging, and/or biomechanical (objective) outcome measurement and found both positive subjective and objective outcomes in 16 studies and positive

    Chronic pain is common in HIV, but incompletely characterized, including its underlying etiologies, its effect on healthcare utilization, and the characteristics of affected patients in the HIV primary care setting. These data are needed to design and justify appropriate clinic-based pain management services. Using a clinical data warehouse, we analyzed one year of data from 638 patients receiving standard-of-care antiretroviral therapy in a large primary care HIV clinic, located in the Harlem neighborhood of New York City. We found that 40% of patients carried one or more chronic pain diagnoses. The most common diagnoses were degenerative musculoskeletal disorders (eg, degenerative spinal disease and osteoarthritis), followed by neuropathic pain and headache disorders. Many patients (16%) had multiple chronic pain diagnoses. Women, older patients, and patients with greater burdens of medical illness, and psychiatric and substance use comorbidities were disproportionately represented among those with chronic pain diagnoses. Controlling for overall health status, HIV patients with chronic pain had greater healthcare utilization including emergency department visits and radiology procedures. In summary, our study demonstrates the high prevalence of chronic pain disorders in the primary care HIV clinic. Colocated interventions for chronic pain in this setting should not only focus on musculoskeletal pain but also account for complex multifaceted pain syndromes, and address the unique biopsychosocial features of this population. Furthermore, because chronic pain is prevalent in HIV and associated with increased healthcare utilization, developing clinic-based pain management programs could be cost-effective.

    Chronic pain is frequently experienced in adolescents; it affects functionality and requires interventions to decrease the impairments caused by pain. Cognitive behavioral therapy (CBT) has been analyzed in numerous studies that evaluated its effects on reducing the different types of chronic pain in children and adolescents. Interestingly, the outcome of CBT was initially focused on pain intensity, but, because there is no correspondence between children's pain intensity and level of disability, the ability to participate in school and social and recreational activities have been the primary focus of recent studies. There are innovative methods of CBT (such as the third generation of CBT) with and without the use of technology that facilitates the availability of this psychological treatment to adolescents with chronic pain, optimizing its accessibility and comprehensiveness, and maintaining its effectiveness. In the future, specific types of CBT could be specific to the diagnosis of chronic pain in the adolescent, sociodemographics, and other unique features. Parents of children with chronic pain are usually included in these programs, either as coaches in the intervention or as recipients of psychological therapies (including CBT) to optimize benefits. CBT has no adverse effect on chronic pain in adolescents, and there is no literature that makes reference to the effectiveness of CBT in preventing chronic pain in adolescents. A review of the role of CBT in chronic pain in adolescents via a PubMed database search was performed to identify the role of CBT in the management of chronic pain in adolescents.

    Objective To investigate the incidence and pre-operative risk factors for developing pelvic pain after hysteroscopic sterilization using the Essure™ micro-inserts Design Retrospective cohort study (Canadian Task Force classification II-2). Setting University Medical Center Patients A total of 458 patients who underwent hysteroscopic sterilization with Essure™ between January 1, 2005 and June 30, 2012. Results The incidence of acute pelvic pain after hysteroscopic sterilization was 8.1%, and the incidence of persistent pain after 3 months post-procedure was 4.2%. The range of presentation with pain was 1 to 469 days, with a mean time of 56 days. Of the patients that developed chronic pelvic pain after the procedure, 75% presented within 130 days of the procedure. Patients with previous diagnoses of any chronic pain (chronic pelvic pain, chronic low back pain, chronic headache, and fibromyalgia) were more likely to report both acute pain (OR 6.81, 95% CI 2.95,15.73) and chronic pain (OR 6.15, 95% CI 2.10,18.10) after hysteroscopic sterilization. Conclusions Pelvic pain may develop after hysteroscopic sterilization. Patients with preexisting chronic pain diagnoses may be at increased risk of developing pelvic pain after the procedure. Fifty percent of new pelvic pain after Essure™ placement will resolve by 3 months. PMID:24952343

    Dystrophy is a main factor of CRPS. A large number of patients do not develop dystrophy but, instead, they suffer from pain with limitation in movement, possible paraesthesia and/or swelling. This is then a chronic regional pain syndrome or (shoulder-arm-) hand-finger syndrome. These patients should never be confronted with the diagnosis Morbus Sudeck or algodystrophy, which are today also well known among non-professionals, to avoid pushing them into a status of constant severe invalidity. Histories, clinical examination, as well as a good personal understanding of the patient are indispensable. Knowing that pain, or the extent of pain, remains subjective until today, the clinical diagnosis depends on the absence of side differences in: a) the circumference of soft tissues of both upper extremities; b) the callosity of the palm; c) the bone-density. These three parameters allow verification of the consequences of the pain complaints (indirect pain verification). It is essential to find the cause for their suffering and to treat it as far as possible: 1) Too long and inappropriate immobilisation (patient's suffering not considered sufficiently). These patients can recover quickly when the right diagnosis is made in good time. 2) Limitation of movement due to scar, neuroma, or elongation pain: a) bizarre functional disabilities can develop; b) due to the patient's complaints, one or several operations would finally be performed, which will not lead to an improvement but rather to an aggravation of the pain; c) socially-induced purposeful pain increase, the typical statement of the patient will be: "I can't stand it any longer". Patients who are socially over-burdened, or have psycho-social problems, may experience a decline of performance or a post-traumatic stress disorder. Several patients will be introduced as illustrations for each of the relevant groups. PMID:20205065

    Although substantial evidence has established that microglia and astrocytes play a key role in the establishment and maintenance of persistent pain in animal models, the role of glial cells in human pain disorders remains unknown. Here, using the novel technology of integrated positron emission tomography-magnetic resonance imaging and the recently developed radioligand (11)C-PBR28, we show increased brain levels of the translocator protein (TSPO), a marker of glial activation, in patients with chronic low back pain. As the Ala147Thr polymorphism in the TSPO gene affects binding affinity for (11)C-PBR28, nine patient-control pairs were identified from a larger sample of subjects screened and genotyped, and compared in a matched-pairs design, in which each patient was matched to a TSPO polymorphism-, age- and sex-matched control subject (seven Ala/Ala and two Ala/Thr, five males and four females in each group; median age difference: 1 year; age range: 29-63 for patients and 28-65 for controls). Standardized uptake values normalized to whole brain were significantly higher in patients than controls in multiple brain regions, including thalamus and the putative somatosensory representations of the lumbar spine and leg. The thalamic levels of TSPO were negatively correlated with clinical pain and circulating levels of the proinflammatory citokine interleukin-6, suggesting that TSPO expression exerts pain-protective/anti-inflammatory effects in humans, as predicted by animal studies. Given the putative role of activated glia in the establishment and or maintenance of persistent pain, the present findings offer clinical implications that may serve to guide future studies of the pathophysiology and management of a variety of persistent pain conditions.

    Background Chronic neuropathic pain affects 1%–2% of the adult population and is often refractory to standard pharmacologic treatment. Patients with chronic pain have reported using smoked cannabis to relieve pain, improve sleep and improve mood. Methods Adults with post-traumatic or postsurgical neuropathic pain were randomly assigned to receive cannabis at four potencies (0%, 2.5%, 6% and 9.4% tetrahydrocannabinol) over four 14-day periods in a crossover trial. Participants inhaled a single 25-mg dose through a pipe three times daily for the first five days in each cycle, followed by a nine-day washout period. Daily average pain intensity was measured using an 11-point numeric rating scale. We recorded effects on mood, sleep and quality of life, as well as adverse events. Results We recruited 23 participants (mean age 45.4 [standard deviation 12.3] years, 12 women [52%]), of whom 21 completed the trial. The average daily pain intensity, measured on the 11-point numeric rating scale, was lower on the prespecified primary contrast of 9.4% v. 0% tetrahydrocannabinol (5.4 v. 6.1, respectively; difference = 0.7, 95% confidence interval [CI] 0.02–1.4). Preparations with intermediate potency yielded intermediate but nonsignificant degrees of relief. Participants receiving 9.4% tetrahydrocannabinol reported improved ability to fall asleep (easier, p = 0.001; faster, p < 0.001; more drowsy, p = 0.003) and improved quality of sleep (less wakefulness, p = 0.01) relative to 0% tetrahydrocannabinol. We found no differences in mood or quality of life. The most common drug-related adverse events during the period when participants received 9.4% tetrahydrocannabinol were headache, dry eyes, burning sensation in areas of neuropathic pain, dizziness, numbness and cough. Conclusion A single inhalation of 25 mg of 9.4% tetrahydrocannabinol herbal cannabis three times daily for five days reduced the intensity of pain, improved sleep and was well tolerated.

    Background Ischemia-reperfusion (I/R) injuries consist of enhanced oxidative and inflammatory responses along with microvascular dysfunction following prolonged ischemia and reperfusion. Since I/R injuries induce chronic postischemia pain (CPIP) in laboratory animals, it is possible that surgical procedures utilizing prolonged ischemia may result in chronic postoperative pain. Glycemic modulation during ischemia and reperfusion could impact pain following I/R injury, as glucose triggers oxidative, inflammatory and thrombotic reactions, whereas insulin has anti-oxidative, anti-inflammatory and vasodilatory properties. Methods 110 rats underwent a 3-h period of ischemia followed by reperfusion to produce CPIP. CPIP rats had previously been divided into 6 groups with differing glycemic-modulation paradigms: 1) normal feeding; 2) fasting; 3) fasting with normal saline administration; 4) fasting with dextrose administration; 5) normal feeding with insulin administration; and 6) normal feeding with dextrose and insulin administration. Blood glucose levels were assessed during ischemia and reperfusion in these separate groups of rats, and they were tested for mechanical and cold allodynia over the following 21 days (on days 2, 5, 7, 9, 12 and 21 post-I/R injury). Results I/R injury in rats with normoglycemia or relative hyperglycemia (groups 1, 4) led to significant mechanical and cold allodynia; conversely, relative hypoglycemia associated with insulin treatment or fasting (groups 2, 3, and 5) reduced allodynia induced by I/R injury. Importantly, insulin treatment did not reduce allodynia when administered to fed rats given dextrose (group 6). Conclusion Our results suggest that glycemic levels at the time of I/R injury significantly modulate postinjury pain thresholds in CPIP rats. Strict glycemic control during I/R injury significantly reduces CPIP pain and, and conversely, hyperglycemia significantly enhances it, which could have potential clinical applications

    The aim of this article is to report the development and preliminary testing of a prototype computerized adaptive test of chronic pain (CHRONIC PAIN-CAT) conducted in two stages: 1) evaluation of various item selection and stopping rules through real data simulated administrations of CHRONIC PAIN-CAT; 2) a feasibility study of the actual prototype CHRONIC PAIN-CAT assessment system conducted in a pilot sample. Item calibrations developed from a US general population sample (N=782) were used to program a pain severity and impact item bank (k=45) and real data simulations were conducted to determine a CAT stopping rule. The CHRONIC-PAIN CAT was programmed on a tablet PC using QualityMetric's Dynamic Health Assessment (DYHNA®) software and administered to a clinical sample of pain sufferers (n=100). The CAT was completed in significantly less time than the static (full item bank) assessment (p<.001). On average, 5.6 items were dynamically administered by CAT to achieve a precise score. Scores estimated from the two assessments were highly correlated (r=.89) and both assessments discriminated across pain severity levels (p<.001, RV=.95). Patients’ evaluations of the CHRONIC PAIN-CAT were favourable. Perspective This report demonstrates that the CHRONIC PAIN-CAT is feasible for administration in a clinic. The application has the potential to improve pain assessment and help clinicians manage chronic pain. PMID:19595636

    The intersection between chronic health conditions, drug use, and treatment seeking behavior among adults in the criminal justice system has been largely understudied. This study examined whether chronic pain was associated with opiate use, other illicit drug use, and drug-related arrests in a sample of substance-using probationers. We expected that probationers with chronic pain-related diagnoses would report more opiate use and drug-related arrests. This study used baseline data from 250 adults on probation in Baltimore, Maryland and Dallas, Texas who were participating in a larger clinical trial. Eighteen percent of probationers in this sample reported suffering from chronic pain. In bivariate analyses, probationers with chronic pain reported more drug-related arrests (t=-1.81; p<0.05) than those without chronic pain. Multivariate analyses support the hypothesis that probationers who reported chronic pain were marginally more likely to use opiates (OR=2.37; 95% CI .89-1.05) and non-opiate illicit drugs (OR=3.11; 95% CI 1.03-9.39) compared to offenders without chronic pain. In summary, these findings suggest that adults under probation supervision who suffer from chronic pain may be involved in criminal activity (specifically, drug-related criminal activity) in an effort to self-medicate their physical health condition(s). Screening probationers for chronic pain in the probation setting and referring these adults to pain management treatment may be an important step in advancing public safety.

    The experience of pain in humans is modulated by endogenous opioids, but it is largely unknown how the opioid system adapts to chronic pain states. Animal models of chronic pain point to upregulation of opioid receptors (OpR) in the brain, with unknown functional significance. We sought evidence for a similar relationship between chronic pain and OpR availability in humans. Using positron emission tomography and the radiotracer (11)C-diprenorphine, patients with arthritis pain (n = 17) and healthy controls (n = 9) underwent whole-brain positron emission tomography scanning to calculate parametric maps of OpR availability. Consistent with the upregulation hypothesis, within the arthritis group, greater OpR availability was found in the striatum (including the caudate) of patients reporting higher levels of recent chronic pain, as well as regions of interest in the descending opioidergic pathway including the anterior cingulate cortex, thalamus, and periaqueductal gray. The functional significance of striatal changes were clarified with respect to acute pain thresholds: data across patients and controls revealed that striatal OpR availability was related to reduced pain perception. These findings are consistent with the view that chronic pain may upregulate OpR availability to dampen pain. Finally, patients with arthritis pain, compared with healthy controls, had overall less OpR availability within the striatum specifically, consistent with the greater endogenous opioid binding that would be expected in chronic pain states. Our observational evidence points to the need for further studies to establish the causal relationship between chronic pain states and OpR adaptation.

    Background Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly taken orally, but they are also available in topical preparations to be applied to or rubbed onto the skin of a painful joint, typically one affected by arthritis, with the aim of relieving pain locally. Topical NSAIDs are widely used in some parts of the world for acute and chronic painful conditions, but have not been universally accepted until recently. One of the problems has been that older clinical studies were generally short, lasting four weeks or less, and short duration studies are not regarded as adequate in ongoing painful conditions. Objectives To examine the use of topical NSAIDs in chronic musculoskeletal pain, focusing on studies of high methodological quality, and examining the measured effect of the preparations according to study duration. The principal aim was to estimate treatment efficacy in longer duration studies of at least 8 weeks. Search methods A series of electronic searches, together with bibliographic searches, and searches of in-house databases were combined with electronic searches of clinical trial registers and manufacturers of topical NSAIDs, or companies known to be actively researching topical NSAIDs. There had to be at least 10 participants in each treatment arm, with application of treatment at least once daily. Selection criteria Randomised, double blind studies with placebo or active comparators, where at least one treatment was a topical NSAID product, in any topical formulation (cream, gel, patch, solution), in studies lasting at least two weeks. Data collection and analysis Two review authors independently assessed study quality and validity, and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk (RR) and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Information was available from 7688 participants in 34 studies from 32 publications; 23 studies

    Disturbances in family functioning have been identified in youth with chronic pain and are associated with worse child physical and psychological functioning. Assessment measures of family functioning used in research and clinical settings vary. This systematic review summarizes studies investigating relationships among family functioning, pain and pain-related disability in youth with chronic pain. Sixteen articles were reviewed. All studies were cross-sectional, seven utilized between-group comparisons (chronic pain versus healthy/control) and twelve examined within-group associations among family functioning, pain and/or pain-related disability. Studies represented youth with various pain conditions (e.g., headache, abdominal pain, fibromyalgia) aged 6 – 20 years. Findings revealed group differences in family functioning between children with chronic pain and healthy controls in five of seven studies. Significant associations emerged among family variables and pain-related disability in six of nine studies with worse family functioning associated with greater child disability; relationships between family functioning and children’s pain were less consistent. Different patterns of results emerged depending on family functioning measure used. Overall, findings showed that families of children with chronic pain generally have poorer family functioning than healthy populations, and that pain-related disability is more consistently related to family functioning than pain intensity.

    Chronic pain is multi-dimensional. At the physical level itself, beyond the nociceptive pathway, there is hyper arousal state of the components of the nervous system, which negatively influences tension component of the muscles, patterns of breathing, energy levels and mindset, all of which exacerbate the distress and affect the quality of life of the individual and family. Beginning with the physical body, Yoga eventually influences all aspects of the person: vital, mental, emotional, intellectual and spiritual. It offers various levels and approaches to relax, energize, remodel and strengthen body and psyche. The asanas and pranayama harmonize the physiological system and initiate a “relaxation response” in the neuro endocrinal system. This consists of decreased metabolism, quieter breathing, stable blood pressure, reduced muscle tension, lower heart rate and slow brain wave pattern. As the neural discharge pattern gets modulated, hyper arousal of the nervous system and the static load on postural muscle come down. The function of viscera improves with the sense of relaxation and sleep gets deeper and sustained; fatigue diminishes. Several subtle level notional corrections can happen in case the subject meditates and that changes the context of the disease, pain and the meaning of life. Meditation and pranayama, along with relaxing asanas, can help individuals deal with the emotional aspects of chronic pain, reduce anxiety and depression effectively and improve the quality of life perceived.

    The article discusses possible effects of the use of analgesics during pregnancy. It summarizes the pertinent literature and reports some previously unpublished data from the Swedish Medical Birth Register. Most likely the use of analgesics does not cause spontaneous abortion. Only small malformation risk increases are seen after the use of opioids and perhaps non-steroid anti-inflammatory drug (NSAID) use. If possible, the latter should be avoided during the first trimester. If exposure has occurred there is no reason to consider an interruption of the pregnancy. Continued use of analgesics may increase the risk of preeclampsia and of preterm birth, especially valid for opioids. Use of acetylsalicylic acid (ASA) in late pregnancy should be avoided because of the risk of bleeding and (valid also for NSAIDs) premature closure of the ductus arteriosus. A small risk for neonatal abstinence syndrome may exist after the use of opioids for chronic pain, notably during the third trimester and long-lasting effects on child development can possibly occur. For a woman with chronic pain, adequate use of pain killers during pregnancy is needed. It is prudent to avoid ASA and NSAIDs towards the end of the pregnancy, while acetaminophen is an acceptable option all through pregnancy. If continued use of opioids is necessary, the associated risks are low. Triptans can be used for migraine during pregnancy. If possible sumatriptan is preferable to other triptans as data for the latter are largely lacking. Ergots are preferably avoided as not enough data are available. PMID:27154242

    Study Objectives: To determine whether an extended bedtime in sleepy and otherwise healthy volunteers would increase alertness and thereby also reduce pain sensitivity. Setting: Outpatient with sleep laboratory assessments. Participants and Interventions: Healthy volunteers (n = 18), defined as having an average daily sleep latency on the Multiple Sleep Latency Test (MSLT) < 8 min, were randomized to 4 nights of extended bedtime (10 hr) (EXT) or 4 nights of their diary-reported habitual bedtimes (HAB). On day 1 and day 4 they received a standard MSLT (10:00, 12:00, 14:00, and 16:00 hr) and finger withdrawal latency pain testing to a radiant heat stimulus (10:30 and 14:30 hr). Results: During the four experimental nights the EXT group slept 1.8 hr per night more than the HAB group and average daily sleep latency on the MSLT increased in the EXT group, but not the HAB group. Similarly, finger withdrawal latency was increased (pain sensitivity was reduced) in the EXT group but not the HAB group. The nightly increase in sleep time during the four experimental nights was correlated with the improvement in MSLT, which in turn was correlated with reduced pain sensitivity. Conclusions: These are the first data to show that an extended bedtime in mildly sleepy healthy adults, which resulted in increased sleep time and reduced sleepiness, reduces pain sensitivity.

    Background Chronic musculoskeletal pain is highly prevalent, disabling, and costly, and has many negative effects on quality of life. The aim of this study was to investigate factors associated with higher reported pain levels in patients with chronic musculoskeletal pain among demographic, clinical, and psychological factors, and to evaluate whether insomnia is independently associated with pain intensity in this population. Methods A total of 357 patients with chronic musculoskeletal pain (pain duration ≥ six months) satisfied the study inclusion criteria and were included in the analyses. Patient demographics, clinical, and psychological factors were evaluated with hierarchical multivariate logistic analysis to identify factors associated with severe pain (NRS [numeric rating scale] ≥ 7). Hierarchical linear regression analysis also performed to identify factors associated with pain intensity (0 to 10 NRS). Results Multivariate logistic analyses revealed older age (OR [odds ratio] = 1.017, 95% CI [confidence interval] 1.001–1.032, P = 0.034), high anxiety level (OR = 1.162, 95% CI 1.020–1.324, P = 0.024), high pain catastrophizing (OR = 1.043, 95% CI 1.007–1.081, P = 0.018), and severe insomnia (OR = 1.112, 95% CI 1.057–1.170, P<0.001) were significantly associated with severe pain. Hierarchical linear regression analysis showed age (β = 0.106, P = 0.041), pain catastrophizing (β = 0.249, P<0.001), and insomnia (β = 0.286, P<0.001) were significantly associated with pain intensity. The variance in pain intensity explained by the final model was 32.2%. Conclusions Older age, severe insomnia, and high pain catastrophizing were significantly associated with higher reported pain levels. Insomnia was independently associated with pain intensity, even after controlling for various demographic and clinical factors. These factors should be considered when devising pain management strategies for this population. PMID:27636367

    National Institutes of Health category III prostatitis, also known as chronic prostatitis/chronic pelvic pain syndrome, is a common condition with significant impact on quality of life. This clinically defined syndrome has a multifactorial etiology and seems to respond best to multimodal therapy. At least half of these patients have pelvic floor spasm. There are several approaches to therapy including biofeedback, acupuncture, and myofascial release physical therapy. However, the only multicenter study of pelvic floor physical therapy for pelvic floor spasm in men failed to show an advantage over conventional Western massage. We have proposed a clinical phenotyping system called UPOINT to classify patients with urologic chronic pelvic pain and subsequently direct appropriate therapy. Here, we review the current approach to category III prostatitis and describe how clinical phenotyping with UPOINT may improve therapy outcomes. PMID:20490725

    The pathophysiology of the chronic pain following spinal cord injury (SCI) is unclear. In order to study it's underlying mechanism we characterized the neurological profile of SCI subjects with (SCIP) and without (SCINP) chronic pain. Characterization comprised of thermal threshold testing for warmth, cold and heat pain and tactile sensibility testing of touch, graphesthesia and identification of speed of movement of touch stimuli on the skin. In addition, spontaneously painful areas were mapped in SCIP and evoked pathological pain--allodynia, hyperpathia and wind-up pain evaluated for both groups. Both SCIP and SCINP showed similar reductions in both thermal and tactile sensations. In both groups thermal sensations were significantly more impaired than tactile sensations. Chronic pain was present only in skin areas below the lesion with impaired or absent temperature and heat-pain sensibilities. Conversely, all the thermally impaired skin areas in SCIP were painful while painfree areas in the same subjects were normal. In contrast, chronic pain could be found in skin areas without any impairment in tactile sensibilities. Allodynia could only be elicited in SCIP and a significantly higher incidence of pathologically evoked pain (i.e. hyperpathia and wind-up pain) was seen in the chronic pain areas compared to SCINP. We conclude that damage to the spinothalamic tract (STT) is a necessary condition for the occurrence of chronic pain following SCI. However, STT lesion is not a sufficient condition since it could also be found in SCINP. The abnormal evoked pain seen in SCIP is probably due to neuronal hyperexcitability in these subjects. The fact that apparently identical sensory impairments manifest as chronic pain and hyperexcitability in one subject but not in another implies that either genetic predisposition or subtle differences in the nature of spinal injury determine the emergence of chronic pain following SCI.

    Few studies have provided a detailed characterization of pain in patients with chronic obstructive pulmonary disease (COPD). The aims of this cross-sectional study were to describe the occurrence, intensity, locations, and level of interference associated with pain, as well as pain relief; to identify differences in demographic, clinical, and symptom characteristics between COPD patients with and without pain; and to determine which demographic, clinical, and symptom characteristics were associated with average pain, worst pain, and pain interference. A total of 258 patients with COPD provided information on demographic characteristics; comorbidities; respiratory parameters including dyspnea; body mass index; and symptom characteristics (i.e., anxiety, depression, sleep disturbance, and fatigue). Pain was measured using the Brief Pain Inventory. Of these 258 COPD patients, 157 (61%) reported pain. Multiple linear regression analyses were performed to determine which demographic, clinical, and symptom characteristics were associated with average pain severity, worst pain severity, and mean pain interference. Lower stages of COPD were associated with higher worst pain and higher pain interference scores. Higher depression scores were associated with higher average pain and higher pain interference scores. In addition, higher number of pain locations was associated with higher average and higher worst pain severity scores. Findings from this study confirm that pain is a significant problem and highlights the need for specific pain management interventions for patients with COPD. More research is needed about specific pain characteristics and symptoms to gain an increased knowledge about the causes of pain in these patients. PMID:27095390

    Purpose Chronic pain is a widespread and debilitating condition, encountered by physicians in a variety of practice settings. Although many pharmacologic and behavioral strategies exist for the management of this condition, treatment is often unsatisfactory. Scrambler Therapy is a novel, non-invasive pain modifying technique that utilizes transcutaneous electrical stimulation of pain fibers with the intent of re-organizing maladaptive signaling pathways. This review was conducted to further evaluate what is known regarding the mechanisms and mechanics of Scrambler Therapy and to investigate the preliminary data pertaining to the efficacy of this treatment modality. Methods The PubMed/Medline, SCOPUS, EMBASE, and Google Scholar databases were searched for all articles published on Scrambler Therapy prior to November 2015. All case studies and clinical trials were evaluated and reported in a descriptive manner. Results To date, 20 reports, of varying scientific quality, have been published regarding this device; all but one small study, published only as an abstract, provided results that appear positive. Conclusion The positive findings from preliminary studies with Scrambler Therapy support that this device provides benefit for patients with refractory pain syndromes. Larger, randomized studies are required to further evaluate the efficacy of this approach. PMID:27041741

    Pelvic pain is a common gynecologic complaint. Retroperitoneal pelvic tumors are rarely a cause of pelvic pain. Neurofibroma is an uncommon pelvic retroperitoneal tumor, and only 17 cases are reported to date. A 38-year-old woman with chronic pelvic pain had a soft fixed mass that was the size of an orange in the right posterolateral fornix, with a normal uterus on pelvic examination, and a mass of 6.3 × 5.2 cm with mixed echotexture on the right side separate from both ovaries on transvaginal ultrasonography. A provisional diagnosis of retroperitoneal mass probably a retroperitoneal teratoma was made. Laparoscopy was performed; an ill-defined retroperitoneal soft tissue mass of about 6 cm was seen on the right pararectal and presacral area, displacing the rectum toward the left side. The mass was soft and jellylike without a cyst wall. Histopathologic study and immunohistochemistry results were consistent with neurofibroma of the sacrococcygeal regions. To our knowledge this is the third case of sacrococcygeal neurofibroma treated by complete laparoscopic excision. Gynecologists should keep sacrococcygeal neurofibroma as a differential diagnosis of pelvic pain with atypical location of a pelvic mass. A high index of suspicion and an appropriate imaging technique are needed for accurate diagnosis. Laparoscopy seems to be a safe and effective method of managing retroperitoneal presacral neurofibromas.

    Chronic pain in adults with sickle cell disease (SCD) is a complex multidimensional experience that includes biological, psychological, sociological, and spiritual factors. To date, three models of pain associated with SCD (i.e., biomedical model; biopsychosocial model for SCD pain; Health Belief Model) are published. The biopsychosocial (BPS) multidimensional approach to chronic pain developed by Turk and Gatchel is a widely used model of chronic pain. However, this model has not been applied to chronic pain associated with SCD. In addition, a spiritual/religious dimension is not included in this model. Because spirituality/religion is central to persons affected by SCD, this dimension needs to be added to any model of chronic pain in adults with SCD. In fact, data from one study suggest that spirituality/religiosity is associated with decreased pain intensity in adults with chronic pain from SCD. A BPS-Spiritual model is proposed for adults with chronic pain from SCD since it embraces the whole person. This model includes the biological, psychological, sociological, and spiritual factors relevant to adults with SCD based on past and current research. The purpose of this paper is to describe an adaptation of Turk and Gatchel’s model of chronic pain for adults with SCD and to summarize research findings that support each component of the revised model (i.e., biological, psychological, sociological, spiritual). The paper concludes with a discussion of implications for the use of this model in research. PMID:24315252

    [Purpose] This study aimed to identify the effects of the CORE exercise program on pain and active range of motion (AROM) in patients with chronic low back pain. [Subjects and Methods] Thirty subjects with chronic low back pain were randomly allocated to two groups: the CORE group (n = 15) and the control group (n = 15). The CORE group performed the CORE exercise program for 30 minutes a day, 3 times a week, for 4 weeks, while the control group did not perform any exercise. The visual analog scale (VAS) and an algometer were used to measure pain, and pain-free AROM in the trunk was measured before and after the intervention. [Results] The CORE group showed significantly decreased VAS scores at rest and during movement and had a significantly increased pressure pain threshold in the quadratus lumborum and AROM in the trunk compared with those in the control group. [Conclusion] This study demonstrated that the CORE exercise program is effective in decreasing pain and increasing AROM in patients with chronic low back pain. Thus, the CORE exercise program can be used to manage pain and AROM in patients with chronic low back pain.

    2014-01-01

    The treatment of chronic pain arising from deep tissues is currently inadequate and there is need for new pharmacological agents to provide analgesia. The endogenous paracrine hormone/neurotransmitter oxytocin is intimately involved in the modulation of multiple physiological and psychological functions. Recent experiments have given clear evidence for a role of oxytocin in the modulation of nociception. The present article reviews the existent human and basic science data related to the direct and indirect effects of oxytocin on pain. Due to its analgesic, anxiolytic, antidepressant and other central nervous system effects, there is strong evidence that oxytocin and other drugs acting through the oxytocin receptor could act as multifunctional analgesics with unique therapeutic value.

    Ten percent of all gynecologic consultations are for chronic pelvic pain, and 20% of patients require a laparoscopy. Chronic pelvic pain affects 15% of all women annually in the United States, with medical costs and loss of productivity estimated at $2.8 billion and $15 billion per year, respectively. Chronic pelvic pain in women may have multifactorial etiology, but 22% have pain associated with musculoskeletal causes. Unfortunately, pelvic musculoskeletal dysfunction is not routinely evaluated as a cause of pelvic pain by gynecologists. A pelvic musculoskeletal examination is simple to perform, is not time-consuming, and is one of the most important components to investigate in all chronic pelvic pain patients. This article describes common musculoskeletal causes of chronic pelvic pain and explains how to perform a simple musculoskeletal examination that can be easily incorporated into the gynecologist physical examination.

    Various phases of solar energy were evaluated for possible medical application, using the Bi-Digital O-Ring Test. A 2-4 minute interval of highly beneficial phase during sunrise and sunset which is comparable or is stronger than (+) Qigong Energy was detected. This energy was stored on 3 x 5 inch index cards. The sun energy stored on the exposed surface had a Bi-Digital O-Ring Test extremely strong positive (+) response, and the opposite side of the index card which was not exposed to the sun showed an equally strong negative (-) response. When the Bi-Digital O-Ring Test strong positive side (+) was applied to the patient's skin above various intractable painful areas with circulatory disturbances, including gangrenous pain, muscle pain, joint pain, & migraine headache, most of the pain disappeared or was significantly reduced within between 10 seconds and 5 minutes, with accelerated wound healing compared with Qigong energy stored paper of the same exposure, which caused pain to disappear within between 1.5 minutes and 15 minutes. When this Special Solar Energy Stored Paper was applied either directly to the skin above cancer positive areas or the midline of the upper chest above the thymus gland representation area, or the occipital area above the medulla oblongata, various cancer related parameters returned to close to normal values, with immediate clinical improvement. The beneficial effects of 10-60 seconds of application of the Special Solar Energy Stored Paper lasted for between 7 and 40 days, depending on the individual and their environmental electromagnetic field, how the special solar energy was stored, and how it was applied to the patient.

    This study aimed to develop a grounded theory to describe and explain the experience of pain and its impact, as reported by the individuals who had pain associated with chronic leg ulceration. The Strauss and Corbin grounded theory approach was used. In-depth interviews were undertaken with 11 people aged ≥ 65 years from Leeds in the north of England. All participants were cared for by home care nurses and had painful leg ulceration. The emergent grounded theory centered on a core category of "The journey to chronic pain." The theory suggested a trajectory consisting of three phases that the patient experiences, where the end result is a chronic pain syndrome. In phase 1, leg ulcer pain has predominantly acute nociceptive properties, and if this is not managed effectively, or ulcers do not heal, persistent pain may develop with both nociceptive and neuropathic properties (i.e., phase 2). If phase 2 pain is not managed effectively, patients may then develop refractory long-term pain (phase 3). Those who progress to phase 3 tend to experience negative consequences such as insomnia, depression, and suicidal ideation. Only when health care professionals understand and acknowledge the persistent and long-term nature of the pain in this patient group can the pain be managed effectively.

    Background Pelvic adhesions are found in up to 50% of women with CPP during investigative surgeries and adhesiolysis is often performed as part of their management although the causal or casual association of adhesions, and the clinical benefit of adhesiolysis in the context of CPP is still unclear. Our aim was to test the hypothesis of whether laparoscopic adhesiolysis leads to significant pain relief and improvement in quality of life (QoL) in patients with chronic pelvic pain (CPP) and adhesions. Methods This was a double-blinded RCT. This study was conducted in 2 tertiary referral hospitals in United Kingdom over 4 years. Women with chronic pelvic pain (CPP) were randomized into having laparoscopic adhesiolysis or diagnostic laparoscopy. Women were assessed at 0, 3 and 6 months for Visual analogue scale scores (VAS) and Quality of Life (QoL) measures (SF-12 and EHP-30). Results A total of 92 participants were recruited; 50 qualified to be randomized, with 26 in the adhesiolysis and 24 in the control group. The results are expressed in median (interquartile ranges). In women who underwent adhesiolysis, there was a significant improvement at 6 months in VAS scores (-17.5 (-36.0 - -5.0) compared to controls (-1.5 (-15.0 – 4.5; p = 0.048); SF-12 scores physical component score (25.0 (18.8 – 43.8)) compared to controls (6.3 (-6.3 – 18.8); p = 0.021), SF-12 emotional component score 32.5 (4.4 – 48.8) compared to controls -5 (-21.3 – 15.0); p < 0.0074) and EHP-30 emotional well being domain 32.5 (4.4 – 48.8) compared to the controls -5 (-21.3 – 15.0; p < 0.0074). Conclusions This study stopped before recruitment reached the statistically powered sample size due to difficulty with enrollment and lack of continued funding. In selected population of women presenting to the gynecological clinic with chronic pelvic pain, adhesiolysis in those who have adhesions may be of benefit in terms of improvement of pain and their quality of life

    Chronic orchalgia is a frustrating clinical problem for both the patient and the physician. We present a 17-year-old boy with a bilateral idiopathic chronic intractable orchalgia with failed conservative treatment. For 2 years, he suffered from severe attacks of scrotal pain that affected his daily activities and caused frequent absence from school. Ultrasound-guided pulsed radiofrequency ablation (PRF) of the genital branches of the genitofemoral nerve performed after local anesthetic nerve block confirmed the diagnosis and yielded 6 weeks of symptom relief. Seven-month follow-up revealed complete satisfactory analgesia. The use of PRF is an effective and non-invasive approach to treat intractable chronic orchalgia. PMID:24843352

  12. Communicating the Experience of Chronic Pain and Illness Through Blogging

    2012-01-01

    Background Although more individuals are sharing their experiences with chronic pain or illness through blogging (writing an Internet web log), research on the psychosocial effects and motivating factors for initiating and maintaining a blog is lacking. Objective The objective was to examine via online questionnaire the perceived psychosocial and health benefits of blogging among patients who use this media to communicate their experience of chronic pain or illness. Methods A 34-item online questionnaire was created, tested, and promoted through online health/disease forums. The survey employed convenience sampling and was open from May 5 to July 2, 2011. Respondents provided information regarding demographics, health condition, initiation and upkeep of blogs, and dynamics of online communication. Qualitative data regarding respondents’ blogging experiences, expectations for blogging, and the perceived effects from blogging on the blogger’s health, interpersonal relationships, and quality of life were collected in the form of written narrative. Results Out of 372 respondents who started the survey, 230 completed the entire questionnaire. Demographic data showed survey respondents to be predominantly female (81.8%) and highly educated (97.2% > high school education and 39.6% with graduate school or professional degrees). A wide spectrum of chronic pain and illness diagnoses and comorbidities were represented. Respondents reported that initiating and maintaining an illness blog resulted in increased connection with others, decreased isolation, and provided an opportunity to tell their illness story. Blogging promoted accountability (to self and others) and created opportunities for making meaning and gaining insights from the experience of illness, which nurtured a sense of purpose and furthered their understanding of their illness. Conclusions Results suggest that blogging about chronic pain and illness may decrease a sense of isolation through the establishment

  13. Surface Electromyographic (SEMG) Biofeedback for Chronic Low Back Pain

    Biofeedback is a process in which biological information is measured and fed back to a patient and clinician for the purpose of gaining increased awareness and control over physiological domains. Surface electromyography (SEMG), a measure of muscle activity, allows both a patient and clinician to have direct and immediate access to muscle functioning that is not possible with manual palpation or visual observation. SEMG biofeedback can be used to help “down-train” elevated muscle activity or to “up-train” weak, inhibited, or paretic muscles. This article presents a historical and clinical overview of SEMG and its use in chronic low back pain assessment and biofeedback training. PMID:27417615

    Chronic pelvic pain in women is a debilitating, costly condition often treated by physical therapists. The etiology of this condition is multifactorial and poorly understood, given the complex interplay of muscles, bones, and soft tissue that comprise the pelvis. There are few guidelines directing treatment interventions for this condition. In the last decade, several investigators have highlighted the role of psychological variables in conditions such as vulvodynia and painful bladder syndrome. Pain-related fear is the focus of the fear-avoidance model (FAM) of pain, which theorizes that some people are more likely to develop and maintain pain after an injury because of their emotional and behavioral responses to pain. The FAM groups people into 2 classes on the basis of how they respond to pain: people who have low fear, confront pain, and recover from injury and people who catastrophize pain—a response that leads to avoidance/escape behaviors, disuse, and disability. Given the presence of pain-related cognitions in women with chronic pelvic pain, including hypervigilance, catastrophizing, and anxiety, research directed toward the application of the FAM to guide therapeutic interventions is warranted. Isolated segments of the FAM have been studied to theorize why traditional approaches (ie, medications and surgery) may not lead to successful outcomes. However, the explicit application of the FAM to guide physical therapy interventions for women with chronic pelvic pain is not routine. Integrating the FAM might direct physical therapists' clinical decision making on the basis of the pain-related cognitions and behaviors of patients. The aims of this article are to provide information about the FAM of musculoskeletal pain and to provide evidence for the relevance of the FAM to chronic pelvic pain in women. PMID:21835893

    Providing comprehensive care for chronic pelvic pain is impeded by time and resource constraints of the standard health care visit. To provide patient education, psychosocial support, and health care assessment, we developed group visits for women with chronic pelvic pain using an evidence-based, holistic nursing approach. In this article, we describe the structure of group visits, the process of conducting Centering group visits focused on empowerment, and the content of a holistic curriculum for women with chronic pelvic pain.

    Musculoskeletal pain (MSP) is a common sequela of traumatic stress exposure. While biological factors contributing to chronic MSP after motor vehicle collision (MVC) have traditionally focused on tissue injury, increasing evidence suggests that neuro/stress/immune processes mediated by stress system activation may play a more dominant role. In a previous study, we found that genetic variants in the hypothalamic-pituitary-adrenal (HPA) axis-related gene FKBP5 influence vulnerability to persistent MSP 6 weeks after MVC. In the present cohort study (n = 855), we evaluated whether genetic variants in several other important HPA axis-related genes, including the glucocorticoid receptor (NR3C1), corticotropin-releasing hormone receptor R1 (CRHR1), and corticotropin-releasing hormone-binding protein (CRHBP), influence risk of chronic MSP over time after MVC. Genetic polymorphism rs7718461 in the CRHBP gene showed significant association (P = 0.0012) with overall pain severity during the year after MVC in regression models controlling for multiple comparisons. Two additional CRHBP alleles in high linkage disequilibrium with rs7718461 also showed trend-level significance. In secondary analyses, a significant interaction between this CRHBP locus (minor allele frequency = 0.33) and time was observed (P = 0.015), with increasing effect observed over time following trauma. A significant CRHBP × FKBP5 interaction was also observed, with substantially increased MSP after MVC in those with a risk allele in bo
