    Greater trochanteric pain is one of the common complaints in orthopedics. Frequent diagnoses include myofascial pain, trochanteric bursitis, tendinosis and rupture of the gluteus medius and minimus tendon, and external snapping hip. Furthermore, nerve entrapment like the piriformis syndrome must be considered in the differential diagnosis. This article summarizes essential diagnostic and therapeutic steps in greater trochanteric pain syndrome. Careful clinical evaluation, complemented with specific imaging studies and diagnostic infiltrations allows determination of the underlying pathology in most cases. Thereafter, specific nonsurgical treatment is indicated, with success rates of more than 90 %. Resistant cases and tendon ruptures may require surgical intervention, which can provide significant pain relief and functional improvement in most cases.

    Originally defined as "tenderness to palpation over the greater trochanter with the patient in the side-lying position," greater trochanteric pain syndrome (GTPS) as a clinical entity, has expanded to include a number of disorders of the lateral, peritrochanteric space of the hip, including trochanteric bursitis, tears of the gluteus medius and minimus and external coxa saltans (snapping hip). Typically presenting with pain and reproducible tenderness in the region of the greater trochanter, buttock, or lateral thigh, GTPS is relatively common, reported to affect between 10% and 25% of the general population. Secondary to the relative paucity of information available on the diagnosis and management of components of GTPS, the presence of these pathologic entities may be underrecognized, leading to extensive workups and delays in appropriate treatment. This article aims to review the present understanding of the lesions that comprise GTPS, discussing the relevant anatomy, diagnostic workup and recommended treatment for trochanteric bursitis, gluteus medius and minimus tears, and external coxa saltans.

    Objectives To describe the prevalence of greater trochanteric pain syndrome (GTPS); to determine whether GTPS is associated with iliotibial band (ITB) tenderness, knee osteoarthritis (OA), body mass index (BMI), or low back pain (LBP); and to assess whether GTPS is associated with reduced hip internal rotation, physical activity, and mobility. Design Cross-sectional, population-based study. Setting Multicenter observational study. Participants Community-dwelling adults (N=3026) ages 50 to 79 years. Interventions Not applicable. Main Outcome Measures Greater trochanteric tenderness to palpation in subjects with complaints of hip pain and no signs of hip OA or generalized myofascial tenderness. Results The prevalence of unilateral and bilateral GTPS was 15.0% and 8.5% in women and 6.6% and 1.9% men. Odds ratio (OR) for women was 3.37 (95% confidence interval [CI], 2.67–4.25), but age and race were not significantly associated with GTPS. In a multivariate model, adjusting for age, sex, ITB tenderness, ipsilateral and contralateral knee OA, BMI, and LBP, ITB tenderness (OR=1.72; 95% CI, 1.34–2.19), knee OA ipsilaterally (OR=3.47; 95% CI, 2.72–4.42) and con-tralaterally (OR=1.74; 95% CI, 1.32–2.28), and LBP (OR=2.79; 95% CI, 2.22–3.50) were positively related to GTPS. In this complete model, BMI was not associated with GTPS (OR=1.10; 95% CI, 0.80–1.52 when comparing ≥ 30 with <25kg/m2). Hip internal rotation range of motion did not differ based on GTPS status. After multivariate adjustment, GTPS did not alter physical activity score, but bilateal GTPS was significantly associated with a higher 20-meter walk time and chair stand time. Conclusions The higher prevalence of GTPS in women and in adults with ITB pain or knee OA indicates that altered lower-limb biomechanics may be related to GTPS. Slower functional performance in those with GTPS suggests that the study of targeted rehabilitation may be useful. A longitudinal study will be necessary to identify

    Greater trochanteric pain syndrome (GTPS) is a common cause of lateral hip pain. Most cases respond to conservative treatments with a few refractory cases requiring surgical intervention. For many years, this condition was believed to be caused by trochanteric bursitis, with treatments targeting the bursitis. More recently gluteal tendinopathy/tears have been proposed as potential causes. Treatments are consequently developing to target these proposed pathologies. At present there is no defined treatment protocol for GTPS. The purpose of this systematic literature review is to evaluate the current evidence for the effectiveness of GTPS interventions, both conservative and surgical. PMID:26955229

    Greater trochanteric pain syndrome (GTPS) is a term used to describe chronic pain overlying the lateral aspect of the hip. This regional pain syndrome, once described as trochanteric bursitis, often mimics pain generated from other sources, including, but not limited to myofascial pain, degenerative joint disease, and spinal pathology. The incidence of greater trochanteric pain is reported to be approximately 1.8 patients per 1000 per year with the prevalence being higher in women, and patients with coexisting low back pain, osteoarthritis, iliotibial band tenderness, and obesity. Symptoms of GTPS consist of persistent pain in the lateral hip radiating along the lateral aspect of the thigh to the knee and occasionally below the knee and/or buttock. Physical examination reveals point tenderness in the posterolateral area of the greater trochanter. Most cases of GTPS are self-limited with conservative measures, such as physical therapy, weight loss, nonsteroidal antiinflammatory drugs and behavior modification, providing resolution of symptoms. Other treatment modalities include bursa or lateral hip injections performed with corticosteroid and local anesthetic. More invasive surgical interventions have anecdotally been reported to provide pain relief when conservative treatment modalities fail.

    Introduction Greater trochanteric pain syndrome (GTPS) is a common condition, the pathogenesis of which is incompletely understood. Although leg-length inequality has been suggested as a potential risk factor for GTPS, this widely held assumption has not been tested. Methods A cross-sectional analysis of greater trochanteric tenderness to palpation was performed in subjects with complaints of hip pain and no signs of hip osteoarthritis or generalized myofascial tenderness. Subjects were recruited from one clinical center of the Multicenter Osteoarthritis Study, a multicenter population-based study of community-dwelling adults aged 50 to 79 years. Diagnosis of GTPS was based on a standardized physical examination performed by trained examiners, and technicians measured leg length on full-limb anteroposterior radiographs. Results A total of 1,482 subjects were eligible for analysis of GTPS and leg length. Subjects' mean ± standard deviation age was 62.4 ± 8.2 years, and 59.8% were female. A total of 372 lower limbs from 271 subjects met the definition for having GTPS. Leg-length inequality (difference ≥ 1 cm) was present in 37 subjects with GTPS and in 163 subjects without GTPS (P = 0.86). Using a variety of definitions of leg-length inequality, including categorical and continuous measures, there was no association of this parameter with the occurrence of GTPS (for example, for ≥ 1 cm leg-length inequality, odds ratio = 1.17 (95% confidence interval = 0.79 to 1.73)). In adjusted analyses, female sex was significantly associated with the presence of GTPS, with an adjusted odds ratio of 3.04 (95% confidence interval = 2.07 to 4.47). Conclusion The present study found no evidence to support an association between leg-length inequality and greater trochanteric pain syndrome. PMID:18510741

    Tumoral calcinosis is a rare syndrome characterized by massive subcutaneous soft tissue deposits of calcium phosphate near the large joints. It is more prevalent in patients with chronic kidney disease undergoing dialysis. A 57-year-old woman was referred to our pain clinic with the complaint of severe pain in the left buttock and lateral hip. The patient had been suffering from chronic kidney disease for 10 years and had been undergoing peritoneal dialysis over the past 5 years. The patient's symptom was initially suspected to be of lumbar origin at the L5 level and a left L5 transforaminal epidural block was performed, but without success. Re-evaluation of the physical examination revealed severe tenderness over the left greater trochanter and piriformis muscle. On ultrasonographic evaluation, multiple mass-like lesions in the left buttock were observed. About 30 mL of fluid was aspirated from the cystic lesions, followed by 30 mL mixture of 0.08% levobupivacaine and triamcinolone 40 mg injected into the bursa under ultrasound guidance, which brought pain relief. Trochanteric bursitis was thought of as the cause of the symptoms. The patient was diagnosed with tumoral calcinosis based on the past medical history, simple plain radiographs, and hip magnetic resonance imaging (MRI). We diagnosed a case of greater trochanteric pain syndrome due to tumoral calcinosis related to chronic kidney disease in a patient whose symptoms had initially been considered to be radiating leg pain caused by lumbar spinal disease. We report our experience of symptomatic improvement following the repeated ultrasound-guided aspiration of calcific fluid and the injection of a mixture of local anesthetic and steroid.

    Disorders causing lateral hip pain are encountered frequently by physicians. Evaluating these problems can be challenging because of the myriad of potential causes, the complex anatomy of the peritrochanteric structures, and the inconsistently described etiologic factors. Misconceptions about the causes of lateral hip pain and tenderness are common, frequently leading to approaches that only provide temporary solutions rather than address the underlying pathology. Trochanteric bursitis is implicated frequently but is seldom the primary cause of pain in chronic cases. It is important to address hip rotator cuff tendinopathy and pelvic core instability. Treatment options include therapeutic exercise, physical modalities, corticosteroid injections, extracorporeal shock wave therapy, and regenerative injection therapies. For recalcitrant cases, surgery may be appropriate. By understanding the anatomy of the peritrochanteric structures, and the pathologic processes most likely responsible for symptomatology and dysfunction, the physician will be prepared to provide effective long-term solutions for this common problem.

    Isolated greater trochanter fractures after total hip arthroplasty are associated with major comorbidities such as debilitating weakness, pain, and dislocation. No definitive standard of care has been established for these fracture. However, it is well known that reestablishing osseous union in these patients is strongly associated with return of functional status. We report a case of an elderly patient with multiple hip revision surgeries now presenting with unilateral greater trochanter fracture. Treatment incorporated the use of a trochanteric claw plate, cerclage wiring, and adjuvant demineralized bone matrix allograft to achieve successful osseous union. This is the first reported use of adjuvant demineralized bone matrix for fixing these fractures.

    Objective To evaluate if pelvic or hip width predisposed women to developing greater trochanteric pain syndrome (GTPS). Design Prospective case control study. Participants Four groups were included in the study: those gluteal tendon reconstructions (n=31, GTR), those with conservatively managed GTPS (n=29), those with hip osteoarthritis (n=20, OA) and 22 asymptomatic participants (ASC). Methods Anterior-posterior pelvic x-rays were evaluated for femoral neck shaft angle; acetabular index, and width at the lateral acetabulum, and the superior and lateral aspects of the greater trochanter. Body mass index, and waist, hip and greater trochanter girth were measured. Data were analysed using a one-way analysis of variance (ANOVA; posthoc Scheffe analysis), then multivariate analysis. Results The GTR group had a lower femoral neck shaft angle than the other groups (p=0.007). The OR (95% CI) of having a neck shaft angle of less than 134°, relative to the ASC group: GTR=3.33 (1.26 to 8.85); GTPS=1.4 (0.52 to 3.75); OA=0.85 (0.28 to 2.61). The OR of GTR relative to GTPS was 2.4 (1.01 to 5.6). No group difference was found for acetabular or greater trochanter width. Greater trochanter girth produced the only anthropometric group difference (mean (95% CI) in cm) GTR=103.8 (100.3 to 107.3), GTPS=105.9 (100.2 to 111.6), OA=100.3 (97.7 to 103.9), ASC=99.1 (94.7 to 103.5), (ANOVA: p=0.036). Multivariate analysis confirmed adiposity is associated with GTPS. Conclusion A lower neck shaft angle is a risk factor for, and adiposity is associated with, GTPS in women. PMID:22547561

    Trochanteric bursitis is a clinical condition which simulates major hip diseases and low back pain, it may also mimic nerve root pressure syndrome. Patients with greater trochanteric bursitis pain syndrome (GTBPS) usually suffer from pain radiating to the posterolateral aspect of the thigh, paraesthesiae in the legs, and tenderness over the iliotibial tract.. The purpose of this study is to indicate the similarity between the clinical features of the GTBPS and those of chronic low back pain, and to highlight the importance of diagnosing GTBPS in patients complaining of low back conditions. Three hundred female patients were included in this prospective study. All patients complained about chronic low back pain or sciatica and had a failed long term conservative treatment. Local injection of the tender peritrochanteric area was only done in half of the patients (group 1). Patients were required to answer the Oswestry Disability Index Questionnaire during all periods of follow-up. Patients of group 1 had a better clinical outcome (p < 0.0005) than the patients in group 2 where no injection was done. We conclude that greater trochanter bursitis pain syndrome is a frequent syndrome which may be associated with low back symptoms. Patients with a long standing history of low back pain and sciatica should be routinely checked for GTBPS. GTBPS is easy to diagnose and can be treated. Peritrochanteric infiltration with glucocorticoids mixed with 2% lidocaine relieves patients from their symptoms for a long period of time. Recurrence should always be expected, but treatment may be repeated.

    Trochanteric bursitis has been used as a general term to describe pain around the greater trochanteric region of the hip. We hypothesised that trochanteric bursitis may not however have an inflammatory component and that accordingly, bursal inflammation has no role in lateral hip pain. This study was designed to test this hypothesis. Patients undergoing primary total hip replacement were enrolled in this prospective, case-controlled, blinded study. Twenty-five patients who met the criteria for diagnosis of trochanteric bursitis (group A) were matched with a control group of 25 patients (group B). Trochanteric bursal samples were harvested from all patients intraoperatively and sent for histological analysis for the presence of inflammation. The intraoperative appearance of the abductor tendon insertion was also noted. None of the samples showed any evidence of acute or chronic inflammatory changes. Intraoperatively, five patients (20%) in group A were noted to have thinning of the gluteus medius tendon but no macroscopic tendon tears were detected in any bursal samples. This study suggests that there is no inflammatory component to so-called trochanteric bursitis, which accordingly casts doubt on both the terminology and the existence of this condition as a separate clinical entity. Clinicians should search for an alternative cause of symptoms in such cases.

    Lateral hip pain along with tenderness of the greater trochanter has been associated with greater trochanteric pain syndrome. Radiographically, this has been associated with gluteus medius pathology on magnetic resonance imaging. This has led some surgeons to conclude that abductor pathology is a primary cause of lateral hip pain. Failure of conservative treatment in the setting of gluteus medius pathology may lead to surgical intervention. In some patients a focal tear of the gluteus medius cannot be visualized and likely represents more diffuse tendinopathy. In these patients we propose micropuncture of the greater trochanter. Similar procedures have shown effectiveness in the elbow and shoulder by eliciting a healing response. Our experience suggests that trochanteric micropuncture at the insertion of the gluteus medius tendon can be effectively performed endoscopically for gluteus medius tendinopathy. PMID:25973381

    Greater trochanteric pain syndrome is an enigmatic but common cause of lateral hip symptoms in middle-aged active women. The most common manifestation of this syndrome is a degenerative tendinopathy of the hip abductors similar to the intrinsic changes seen with rotator cuff pathology in the shoulder. There are no definitive tests to isolate the underlying pathology and palpation is a non-specific means by which to differentiate the source of the pain generator. The physical examination must comprehensively evaluate for a cluster of potential impairments and contributing factors that will need to be addressed to effectively manage the likely functional limitations and activity challenges the syndrome presents to the patient. Compressive forces through increased tension in the iliotibial band should be avoided. Intervention strategies should include education regarding postural avoidance, activity modifications, improvement of lumbopelvic control, and a patient approach to resolving hip joint restrictions and restoring the tensile capabilities of the deep rotators and abductors of the hip. A number of reliable and validated hip-specific self-report outcome tools are available to baseline a patient's status and monitor their progress. Further investigations to identify the epidemiological risk factors, establish effective treatment strategies, and predict prognosis are warranted.

    Lateral hip pain is a common complaint in patients with a history of lower back pain from spinal disease. These patients often are diagnosed and treated for trochanteric bursitis because of localized pain and tenderness in the lateral hip. We presumed numerous scintigraphic features could provide diagnostic criteria for diagnosing gluteus medius tendinitis and trochanteric bursitis. A study was designed to assess the scintigraphic criteria for diagnosis of trochanteric bursitis and to evaluate the relationship of trochanteric bursitis to gluteus medius tendinitis and lumbar degenerative disease in predicting relapse after injection. We evaluated 97 patients with greater trochanteric pain syndrome to find a correlation between trochanteric bursitis, gluteus medius tendinitis, and spinal degenerative disease using scintigraphy and magnetic resonance imaging. We also evaluated predictors for responding to trochanteric injection of local anesthetic/glucocorticoid injection. We found a correlation between lumbar degenerative disease, gluteus medius tendinopathy, and trochanteric bursitis. Of these, 30 of 48 patients (63%) responded to injection of local anesthetic and glucocorticoids. The major predictor of relapse of pain after injection in 18 patients was the presence of moderate to severe lumbar degenerative disease seen on scintigraphic imaging. We propose a mechanistic model of the greater trochanteric pain syndrome to explain the interrelationship and response to therapy. Scintigraphy can provide sensitive and specific diagnoses of gluteus medius tendinitis and trochanteric bursitis.

    Lateral hip pain associated with trochanteric bursitis is a common orthopedic condition, and can be debilitating in chronic or recalcitrant situations. Conservative management is the most common initial treatment and often results in resolution of symptoms and improved patient outcomes. These modalities include rest, activity modification, physical therapy, anti-inflammatory medication, or corticosteroid injections. However, there is a subset of patients in which symptoms persist despite exhaustive conservative modalities. For these patients, trochanteric bursectomy is a surgical option to address persistent pathology. Previous literature indicates that both open and arthroscopic surgical techniques can be used to address the inflamed bursa and results in good patient outcomes. However, recent advances in hip arthroscopy have allowed for improvements in minimally invasive techniques to address intracapsular and extracapsular pathology of the hip, including recalcitrant trochanteric bursitis. The purpose of this manuscript is to describe our technique for a minimally invasive arthroscopic trochanteric bursectomy.

    Soft tissue infection due to Mycobacterium tuberculosis can affect muscle, tendons, fascia, bursa and synovial tissue. Tuberculous trochanteric bursitis is a rare entity that usually affects immunocompromised patients. Manifestations usually occur insidiously, which delays diagnosis and treatment. We present the case of an immunocompetent young woman who came to our department for chronic left hip pain. The study confirms the diagnosis of tuberculous trochanteric bursitis. This case demonstrates the importance of considering a possible infectious origin of bursitis in immunocompetent patients.

    Seventy patients, averaging 82 years of age, were referred for low back pain and/or a suspected herniated disk. Objective neurological deficits consistent with L5 or S1 root involvement were identified in 5 of the 70 patients. Trochanteric bursitis (TB), often mimicking radiculitis, was diagnosed in 31 patients. Trochanteric bursitis was associated with lumbosacral strain and lumbar osteoarthrosis in 21 of 31 patients and with an S1 disk in 1 of those 31 patients. Degenerative joint disease of the ipsilateral hip was present in 4 of 20 of these patients with TB. Six patients with low back pain had both hip and knee arthritis (including two patients with rheumatoid arthritis). Three patients had degenerative hip disease without low back complaints. The remaining patient had TB associated with left hemiparesis. All patients had limitation of lumbosacral motion. Patients with arthritic hips had apparent shortening of the affected leg of one-half inch or greater. Trochanteric bursitis is a common complication of lumbosacral strain, frequently mimicking radiculopathy. Gait alteration associated with back pain or static traction on gluteal musculature during rest therapy may be predisposing factors. The association of TB with hip disease and/or leg length discrepancies was again confirmed.

    Trochanteric bursitis with lateral hip pain is a commonly encountered orthopaedic condition. Although most patients respond to corticosteroid injections, rest, physical therapy (PT), stretching, and anti-inflammatory medications, those with recalcitrant symptoms may require operative intervention. Studies have explored the use of the arthroscope in the treatment of these patients. However, these reports have not addressed the underlying pathology in this chronic condition. We believe that the iliotibial band must be addressed and is the main cause of pain, inflammation, and trochanteric impingement leading to the development of bursitis. We report a new technique for arthroscopic trochanteric bursectomy with iliotibial band release. Our technique involves 2 incisions--one 4 cm proximal to the greater trochanter along the anterior border of the iliotibial band, and the other 4 cm distal and along the posterior border. The 30 degrees arthroscope is introduced through the inferior portal, and a cannula is introduced through the superior portal. A 5.5-mm arthroscopic shaver is inserted through the superior cannula to clear off the surface of the iliotibial band, so that it may be adequately visualized. A hooked electrocautery probe is then used to longitudinally incise the iliotibial band until it no longer rubs, causing impingement over the greater trochanter.

    We report the clinical case of a 76 years-old woman with a subacute trochanteric inflammatory pain with low-grade fever and laboratory markers of acute inflammation, associated with the ultrasonographic evidence of bursitis and radiologic evidence of femoral erosions, that resolved after intravenous antibiotherapy. Although rare, the infectious etiology should be considered in patients with clinical manifestations of bursitis and signs of systemic involvement.

    This study evaluated the use of arthroscopic bursectomy for pain relief in patients with trochanteric bursitis after hip arthroplasty. In this retrospective case series of 12 patients undergoing arthroscopic treatment of recalcitrant trochanteric bursitis after hip arthroplasty, outcomes were assessed via phone interview with a numeric pain rating scale from 1 to 10 and were compared with preoperative pain ratings. Patients were asked the percentage of time they had painless hip function and whether they would have the surgery again. At an average 36-month follow-up (range, 4-85 months), the average numeric pain scale rating improved from 9.3 to 3.3. At an average of 62% of the time, patients had painless use of the hip. Ten of 12 patients in the study felt the pain relief gained was substantial enough to warrant having procedure again. In these patients, arthroscopic bursectomy was a viable option for patients with recalcitrant bursitis after hip arthroplasty.

  8. Trochanteric fossa or piriform fossa of the femur: time for standardised terminology?

    2013-06-01

    Piriform fossa, trochanteric fossa and greater trochanteric tip have each been described as entry points for antegrade femoral nailing. However, the terminology used for these entry points is confusing. The accuracy of the entry point nomenclature in published text and illustrations was recorded in this review study. The trochanteric fossa, a deep depression at the base of the femoral neck is indicated as 'piriform fossa' in the vast majority of the publications. Other publications indicate the insertion site of the tendon of the piriformis muscle on the greater trochanteric tip as 'piriform fossa'. As a result of recurrent terminology error and consistent reproductions of it, the recommended entry point in literature is confusing and seems to need standardisation. The piriform fossa does not appear to exist in the femoral region. The trochanteric fossa is the standard entry point which most surgeons recommend for facilitating a standard straight intramedullary nail, as is in line with the medullary canal. The greater trochanteric tip is the lateral entry point for intramedullary nails with a proximal lateral bend.

    A 66-yr-old white woman presented with progressive complaints of right lateral hip and thigh pain associated with a disabling limp without an antecedent history of trauma. Physical examination revealed localized pain over the right greater trochanter to palpation. A full pain-free range of motion of the right hip was associated with weakness in the hip abductors. The patient ambulated with a compensated right Trendelenburg gait. Subsequent magnetic resonance imaging demonstrated a trochanteric bursitis and an effusion of the hip and a full-thickness tear of the gluteus medius muscle, with both a disruption and retraction of the tendon of an atretic gluteus minimus muscle. Conjoined tendon pathology of both the gluteus medius and minimus as, revealed by magnetic resonance examination, is probably more frequent than heretofore commonly recognized. In patients presenting with "intractable" complaints of a trochanteric bursitis and an ambulatory limp due to weakness in the hip abductors, imaging studies calling attention to a possible tendon rupture may be diagnostic.

    We examined the efficacy of corticosteroid injection as treatment for postarthroplasty trochanteric bursitis and the risk factors for failure of nonoperative treatment. There were 32 (4.6%) cases of postsurgical trochanteric bursitis in 689 primary total hip arthroplasties. Of the 25 hips with follow-up, 11 (45%) required multiple injections. Symptoms resolved in 20 (80%) but persisted in 5. We found no statistically significant differences between patients who did and did not develop trochanteric bursitis, or between those who did and did not respond to treatment. There was a trend toward younger age and greater limb-length discrepancy in nonresponders. In conclusion, (1) corticosteroid injection(s) for postoperative trochanteric bursitis is effective; and (2) nonoperative management may be more likely to fail in young patients and those with leg-length discrepancy.

    Background There are several different techniques commonly used to perform intramedullary (IM) nailing of the femur to fix femoral fractures. We sought to identify significant differences in outcomes of studies comparing 1) trochanteric and piriformis entry and 2) antegrade and retrograde entry in IM nailing of the femur. Methods We searched MEDLINE, Cochrane and Embase databases and the Orthopaedic Trauma Association and American Academy of Orthopaedic Surgeons websites for comparative studies published from inception to November 2015. Criteria used to select articles for detailed review included use of antegrade and retrograde entry point or use of trochanteric and piriformis entry point for IM nailing of the femur in adult patients. Functional and technical outcomes were extracted from accepted studies. Results We identified 483 potential studies, of which 52 were eligible. Of these, we included 13 publications and 2 abstracts (2 level I, 7 level II and 6 level III studies). Trochanteric entry significantly reduced operative duration by 14 min compared with piriformis entry (p = 0.030). Retrograde nailing had a greater risk of postoperative knee pain than antegrade nailing (p = 0.05). On the other hand, antegrade nailing had significantly more postoperative hip pain (p = 0.003) and heterotopic ossification (p < 0.001) than retrograde nailing. No significant differences in functional outcomes were observed. Conclusion Although some significant differences were found, the varying quality of studies made recommendation difficult. Our meta-analysis did not confirm superiority of either antegrade over retrograde or trochanteric over piriformis entry for IM nailing of the femur. Level of evidence Level III therapeutic.

    To evaluate the effect of prophylactic epiphyseodesis of the greater trochanter in Perthes' disease, 62 children with unilateral Perthes' disease who underwent trochanteric epiphyseodesis combined with varus osteotomy of the femur during the active stage of the disease (mean age at surgery: 8.4 y) and 20 controls were followed up until skeletal maturity. On radiographs taken at skeletal maturity, the articulo-trochanteric distance, the center-trochanteric distance, the length of the abductor lever arm, the neck-shaft angle, the radius of the femoral head, and the Reimer's migration index of normal and affected hips were measured. The shape of the femoral head was assessed according to the criteria of Mose. The range of hip motion, the strength of hip abduction, and limb lengths were measured and the Trendelenburg sign was elicited. The mean values of articulo-trochanteric distance and center-trochanteric distance were greater and the frequency of a positive Trendelenburg sign was less in children who had undergone trochanteric epiphyseodesis than in children who had no surgery (P<0.01). Trochanteric epiphyseodesis achieved optimal trochanteric growth arrest in 60% of operated children; the procedure was not effective in 30%, and in 10% of children there was overcorrection. Logistic regression analysis showed that the size of the femoral head at healing and the age at surgery were variables that significantly influenced the effectiveness of trochanteric growth arrest. At skeletal maturity, the mean shortening of the affected limb in operated children was 0.44 cm (SD 0.68 cm), whereas that of non-operated children was 0.86 cm (SD 0.78 cm) (P<0.05). The range of motion of the hip was excellent and there were no significant differences in the range of motion among children with optimal correction, under-correction, and overcorrection. A probability curve plotted on the basis of a logistic regression model suggests that effective trochanteric arrest may be achieved in a

    Context: Historically, the term greater trochanteric pain syndrome has been used to describe a spectrum of conditions that cause lateral-sided hip pain, including greater trochanteric bursitis, snapping iliotibial band, and/or strains or tendinopathy of the abductor mechanism. Diagnosis of these conditions may be difficult because clinical presentations are variable and sometimes inconclusive. Especially difficult is differentiating intrinsic pain from pain referred to the greater trochanteric region. The purposes of this article are to review the relevant anatomy and pathophysiology of the lateral hip. Evidence Acquisition: Data were collected through a thorough review of the literature conducted through a MEDLINE search of all relevant papers between 1980 and January 2010. Results: Recent advances in imaging and an improved understanding of pathomechanics have helped to guide the evaluation, diagnosis, and appropriate treatment for patients presenting with lateral hip pain. Conclusion: Various diagnostic tools and treatment modalities can be used to effectively manage the athletic patient presenting with lateral hip pain. PMID:23015937

    Several surgical approaches could be used in hip arthroplasty or trauma surgery: anterior, anterolateral, lateral, posterior (with or without trochanterotomy), using or not an orthopedic reduction table. Subtrochanteric and extra-capsular trochanteric fractures (ECTF) are usually treated by internal fixation with mandatory restrictions on weight bearing. Specific complications have been widely described. Mechanical failures are particularly high in unstable fractures. Hip fractures are a major public health issue with a mortality rate of 12%–23% at 1 year. An alternative option is to treat ECTF by total hip arthroplasty (THA) to prevent decubitus complications, to help rapid recovery, and to permit immediate weight bearing as well as quick rehabilitation. However, specific risks of THA have to be considered such as dislocation or cardiovascular failure. The classical approach (anterior or posterior) requires the opening of the joint and capsule, weakening hip stability and the repair of the great trochanter is sometimes hazardous. For 15 years, we have been treating unstable ECTF by THA with cementless stem, dual mobility cup (DMC), greater trochanter (GT) reattachment, and a new surgical approach preserving capsule, going through the fracture and avoiding joint dislocation. Bombaci first described a similar approach in 2008; our trans fractural digastric approach (medial gluteus and lateral vastus) is different. A coronal GT osteotomy is performed when there is no coronal fracture line. It allows easy access to the femoral neck and acetabulum. The THA is implanted without femoral internal rotation to avoid extra bone fragment displacement. With pre-operative planning, cup implantation is easy and stem positioning is adjusted referring to the top of the GT after trial reduction and preoperative planning. The longitudinal osteotomy and trochanteric fracture are repaired with wires and the digastric incision is closed. This variant of Bombaci approach could be

    ABSTRACT Objective: To compare the efficacy of platelet rich plasma (PRP) against corticosteroid on the treatment of trochanteric pain syndrome. Methods: From July 2011 to November 2012, eighteen patients (20 hips) with trochanter pain syndrome were randomized in two groups and treated with platelet rich plasma or triamcinolone infiltration guided by ultrasound. Pain and function were evaluated prior to the intervention and after 10, 30 and 60 days, through the Facial Expressions Scale for Pain and the Western Ontario McMaster and Harris Hip Score questionnaires. Inter-group analysis was performed by Student t-test and intragroup analysis by ANOVA, followed by Bonferroni post hoc test. Statistical significance was set at p <0.05. Results: There was no difference between the groups. The triamcinolone group showed pain reduction (p=0.004) and improved function (p=0.036) through the Harris Hip Score questionnaire at 10, 30 and 60 days after treatment, when compared with the pre- intervention period. The platelet rich plasma group showed no statistical improvement in any of the variables. Conclusion: Up to 60 days, PRP infiltration has no influence on pain relief and function improvement in trochanteric syndrome treatment. Level of Evidence II, Prospective Comparative Study.

    Once used routinely, trochanteric osteotomy in total hip arthroplasty now is usually limited to difficult primary and revision cases. There are three types: the standard trochanteric osteotomy and its variations, the trochanteric slide, and the extended trochanteric osteotomy. Each has unique indications, fixation techniques, and complications. Primary total hip arthroplasty procedures requiring the enhanced exposure provided by trochanteric osteotomy may be needed in patients with hip ankylosis or fusion, protrusio acetabuli, proximal femoral deformities, developmental dysplasia, or abductor muscle laxity. Trochanteric osteotomies in revision arthroplasties, primarily the extended trochanteric osteotomy, facilitate the removal of well-fixed femoral components, provide direct access to the diaphysis for distal fixation, and enhance acetabular exposure.

  17. Relationship between width of greater trochanters and width of iliac wings in tronchanteric bursitis.

    Trochanteric bursitis is a common disorder that is characterized by inflammation of the bursa, superficial to the greater trochanter of the femur, leading to pain in the lateral hip, and often occurs because of acute trauma or repetitive friction involving the iliotibial band, the greater trochanter, and the bursa. In the study reported here, we hypothesized that the increased incidence of bursitis may be the result of the increased prominence of the trochanter in relation to the wings of the iliac crest. Distances between the outermost edges of trochanters and iliac wings were measured in 202 patients from the University of North Carolina Health Care System-101 without a known diagnosis and 101 with a clinical diagnosis of trochanteric bursitis. To determine significance, t tests for nonpaired data were used. Mean (SD) difference between trochanter and iliac wing widths was 28 (20) mm in the group diagnosed with trochanteric bursitis and 17 (18) mm in the control group. The difference between the groups in this regard was significant (P<.00005). In addition, mean (SD) ratio of trochanter widths to iliac wing widths was 1.09 (.06) in the bursitis group and 1.05 (.06) in the control group. The difference between these groups was significant (P<.0005) in this regard as well. Having trochanters wider in relation to iliac wings was associated with the diagnosis of trochanteric bursitis.

    We report a 67-year-old woman with systemic lupus erythematosus and systemic disseminated tuberculosis affecting the femoral trochanteric bursae, a site rarely affected by tuberculosis. For quantification of the inflammation with gallium-67 scintigraphy, we calculated the radioisotope count ratio in the most inflamed areas, the right lateral thorax and bursa of the right greater trochanter. Systemic scanning with this modality allowed evaluation of the extent of lesions and simple quantitative determination of the severity of inflammation, yielding information useful for the follow-up of the patient during the course of tuberculosis treatment.

    Effective pain communication is essential if adequate treatment and support are to be provided. Pain communication is often multimodal, with sufferers utilising speech, nonverbal behaviours (such as facial expressions), and co-speech gestures (bodily movements, primarily of the hands and arms that accompany speech and can convey semantic information) to communicate their experience. Research suggests that the production of nonverbal pain behaviours is positively associated with pain intensity, but it is not known whether this is also the case for speech and co-speech gestures. The present study explored whether increased pain intensity is associated with greater speech and gesture production during face-to-face communication about acute, experimental pain. Participants (N = 26) were exposed to experimentally elicited pressure pain to the fingernail bed at high and low intensities and took part in video-recorded semi-structured interviews. Despite rating more intense pain as more difficult to communicate (t(25)  = 2.21, p =  .037), participants produced significantly longer verbal pain descriptions and more co-speech gestures in the high intensity pain condition (Words: t(25)  = 3.57, p  = .001; Gestures: t(25)  = 3.66, p =  .001). This suggests that spoken and gestural communication about pain is enhanced when pain is more intense. Thus, in addition to conveying detailed semantic information about pain, speech and co-speech gestures may provide a cue to pain intensity, with implications for the treatment and support received by pain sufferers. Future work should consider whether these findings are applicable within the context of clinical interactions about pain.

    The current literature indicates that the standard starting point for intramedullary nailing is the piriform fossa. The accuracy of the entry point for anterograde femoral intramedullary nailing between published texts and relevant illustrations was recorded. The piriform fossa is the site of insertion of the piriform tendon and represents a small, shallow depression located on the tip of the greater trochanter. The trochanteric fossa is a deep depression on the inner surface of the greater trochanter, and in the vast majority of the published data is indicated incorrectly as "piriform fossa". As a result of either a recurrent drawing mismatch or a terminology error, the correct entry point for anterograde femoral intramedullary nailing is confusing and should be indicated in the current literature. The trochanteric fossa appears to be the standard entry point that most surgeons recommend.

    Purpose No study to date has compared the associations of pain intensity, depression, and anxiety with insomnia among outpatients with chronic low back pain (CLBP). This study aimed to investigate this issue. Patients and methods A total of 225 outpatients with CLBP were enrolled from a general orthopedics clinic. The Insomnia Severity Index was used to evaluate sleep quality. Major depressive disorder (MDD) and anxiety disorders were diagnosed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision, Axis I Disorders. Two psychometric scales were used to evaluate depression and anxiety. The Visual Analog Scale was employed to assess pain intensity. Multiple linear regressions were performed to determine the association of insomnia with pain intensity, depression, and anxiety. Results Among the 225 subjects, 58 (25.8%) had clinical insomnia; 83 (36.9%) had severe low back pain; 49 (21.8%) had MDD, including 21 (9.3%) with a current major depressive episode (MDE); and 52 (23.1%) had anxiety disorders. More than half (56.9%) of the subjects with CLBP and clinical insomnia had MDD and/or anxiety disorders. Subjects with a current MDE or anxiety disorders had greater severities of pain and insomnia as compared with subjects without these conditions. After controlling for demographic variables, MDE was more strongly associated with insomnia than severe low back pain; moreover, the severity of depression had a greater association with insomnia than pain intensity. Conclusion The association of depression with insomnia was not inferior to that of pain intensity with insomnia. Among patients with CLBP and insomnia, integration of depression and anxiety treatment into treatment of pain might help to improve sleep quality. PMID:27563244

    Here we report a unique case of chronic occipital neuralgia caused by pathological vascular contact of the left greater occipital nerve. After 12 months of left-sided, unremitting occipital neuralgia, a hypesthesia and facial pain developed in the left hemiface. The decompression of the left greater occipital nerve from pathological contacts with the occipital artery resulted in immediate relief for hemifacial sensory change and facial pain, as well as chronic occipital neuralgia. Although referral of pain from the stimulation of occipital and cervical structures innervated by upper cervical nerves to the frontal head of V1 trigeminal distribution has been reported, the development of hemifacial sensory change associated with referred trigeminal pain from chronic occipital neuralgia is extremely rare. Chronic continuous and strong afferent input of occipital neuralgia caused by pathological vascular contact with the greater occipital nerve seemed to be associated with sensitization and hypersensitivity of the second-order neurons in the trigeminocervical complex, a population of neurons in the C2 dorsal horn characterized by receiving convergent input from dural and cervical structures.

    Objectives: To evaluate valgus subtrochanteric osteotomy for the treatment of trochanteric non-union. Methods: A retrospective study of cases series. From 1998 September to 2009 January, seventeen (17) cases with a diagnosis of non-union of trochanteric fracture were re-operated by the hip group of the Ortophaedic And Traumatology service of the Hospital Geral de Goiania (HGG). The patients presented pain at the fracture site, a femoral varus angle of less than 120°, and non-union of the fracture in the 3rd months after the initial surgery. Results: Patients with ages ranging from 30 to 73 years, with a maximum follow-up of 09 years and minimum of 09 years. The mean time from first surgery to osteotomy was six months. Bone union was observed in 16 patients, with a mean union time of 12 weeks after surgery. The mean hip varus angle was 1050 (1200 to 900). After surgery, the mean hip valgus angle was 1440 (1550 to 1350). We had one unsuccessful case; a 78-year old patient who had osteogtomy, fixed with DHS of 1500, with valgization to 1540. After six months of follow-up without union of the fracture, it was decided to perform total cemented hip artroplasthy, without complications. Conclusion: Valgus subtrochanteric osteotomies can be indicated for the treatment of trochanteric treatment of pseudoarthroses, with good final results for bone union, avoiding the need for total hip artroplasthy and maintaining biological fixation, as well as reestablishing the mechanical and anatomical axis of the affected limb.

    Failure of internal fixation of trochanteric fractures requires repeat surgery in order to avoid the risks of complications affecting bedridden patients. This study was conducted to assess the results of hemi- or total hip arthroplasty with a cementless modular femoral stem, as a salvage operation following early mechanical failure of internal fixation. Twenty nine patients with a mean age of 81.1 years (70-91) were included in the study. Fractures extending into the diaphysis and pathological fractures were excluded, as well as patients who presented late complications. A cementless modular stem designed for metaphyso-diaphyseal anchorage was used in all cases. Twenty-two patients underwent hemiarthroplasty and seven total hip arthroplasty. Four patients died within one year and two were lost to follow-up. The remaining 23 patients were followed for a mean of 20 months (range: 6-89). At the time of last follow-up, 20 were ambulatory with (11 cases) or without support (9 cases) and three were bedridden. There were no intra- or postoperative femoral fractures. Two patients presented an early dislocation after bipolar hemiarthroplasty. One was successfully treated by closed reduction; the other underwent revision with a dual mobility acetabular component because of recurrent dislocation. All the patients reported significant pain relief and functional improvement. Subsidence of the stem greater than 5 mm was noted in three cases, without clinical consequences. The cementless modular femoral stem used in this study appeared as a reliable implant. Primary arthroplasty with such an implant could be considered in selected cases such as markedly unstable fractures and in osteoporotic elderly patients.

    Post-operative trochanteric bursitis is a known complication secondary to the surgical approach in total hip arthroplasty. This phenomenon may be partially attributable to repetitive microtrauma generated when soft tissues rub against implanted hardware. Significant rates of post-operative trochanteric bursitis have been observed following procedures in which a trochanteric fixation device, such as a bolt-washer mechanism or a cable-grip/claw system, is used to secure the trochanteric fragment after trochanteric osteotomy. We present a simple technique for use with a bolt-washer system or grip plate in which trochanteric components are covered in bone wax followed by a layer of cement to decrease friction and to diminish the risk of post-operative bursitis.

    We evaluated whether accelerated knee osteoarthritis (AKOA) was associated with greater pain and other outcomes and if outcomes varied over time differently among those with incident AKOA or common knee osteoarthritis (KOA), which we defined as a gradual onset of disease. We conducted longitudinal analyses among participants in the Osteoarthritis Initiative who had no radiographic KOA at baseline (Kellgren-Lawrence [KL] <2). Participants were considered AKOA if ≥1 knees progressed to KL grade ≥3 and common KOA if ≥1 knees increased in radiographic scoring within 48 months. We defined the index visit as the study visit when they met the AKOA or common KOA criteria. Our observation period included up to 3 years before and after the index visit. Our primary outcome was WOMAC pain converted to an ordinal scale: none (pain score = 0/1 out of 20), mild (pain score = 2/3), and moderate-severe pain (pain score >3). We explored 11 other secondary outcome measures. We performed an ordinal logistic regression or linear models with generalized estimating equations. The predictors were group (AKOA or common KOA), time (seven visits), and a group-by-time interaction. Overall, individuals with AKOA (n = 54) had greater pain, functional disability, and global rating scale as well as slower chair-stand and walking pace compared with those with common KOA (n = 187). There was no significant interaction between group and time for knee pain; however, there was for chair-stand pace and global rating scale. In conclusion, AKOA may be a painful and disabling phenotype that warrants more attention by clinicians and researchers.

    We studied the effect of trochanteric osteotomy in 192 total hip replacements in 140 patients with congenital hip disease. There was bony union in 158 hips (82%), fibrous union in 29 (15%) and nonunion in five (3%). The rate of union had a statistically significant relationship with the position of reattachment of the trochanter, which depended greatly on the pre-operative diagnosis. The pre-operative Trendelenburg gait substantially improved in all three disease types (dysplasia, low and high dislocation) and all four categories of reattachment position. A persistent Trendelenburg gait post-operatively was noticed mostly in patients with defective union (fibrous or nonunion). Acetabular and femoral loosening had a statistically significant relationship with defective union and the position of reattachment of the trochanter. These results suggest that the complications of trochanteric osteotomy in total hip replacement for patients with congenital hip disease are less important than the benefits of this surgical approach.

    Introduction: Biomechanically proximal femoral nail (PFN) is a better choice of implant, still it is associated with screw breakage, cut out of screw through femoral head, Z effect, reverse Z effect, and lateral migration of screws. The purpose of this study is to evaluate the results of augmented PFN in terms of prevention of postoperative complications and failure rates in unstable trochanteric fractures. Material and methods: We carried out a prospective study of 82 cases with unstable trochanteric femoral fractures from April 2010 to December 2015. Forty-two females and 40 males in the age group between 58 and 81 years were included in this study. There were 45 cases of AO 31 A2 (2.2, 2.3) and 37 cases of AO 31 A3 (3.1, 3.2, 3.3). Fractures were fixed by PFN with augmentation by an additional screw from trochanter to inferior quadrant of femoral head or cerclage wire to strengthen the lateral trochanteric wall. Results: The bone healing is observed in all the cases in the mean period of 14.2 weeks. Nine patients developed complications, including lateral migration of neck screws (n = 5), Z effect (n = 1), infection (n = 2), and breakage of distal interlocking bolt in one case. Removal of screws was required in five cases. Patients were followed up for a mean of 8.4 months. At the end of follow-up the Salvati and Wilson hip function was 32 (out of 40) in 88% of patients. Conclusion: The stabilization of lateral trochanteric wall with additional screw or cerclage wire increases the stability of construct. PMID:28186871

    Conservative measures--followed by corticosteroid injection, if necessary--are best. Conservative therapy includes rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and stretching exercises focused on the lower back and sacroiliac joints. Patients whose symptoms persist despite conservative therapy are likely to benefit from an injection of 24 mg betamethasone and 1% lidocaine (or equivalent) into the inflamed bursa. In rare cases of intractable symptoms, surgical procedures such as iliotibial band release, subgluteal bursectomy, and trochanteric reduction osteotomy are options.

    Few reports to date have discussed acute deltoid muscle injury, including partial or complete deltoid muscle detachment from its origin. The present report describes a different pathomechanism and clinical manifestations of deltoid muscle injury. A 52-year-old man experienced acute severe pain in the right shoulder as a result of abrupt elevation of the arm. The deltoid muscle had apparently been scratched by an osteophyte on the greater tuberosity. After arthroscopic excision of the osteophyte, the symptoms resolved completely.

    Extensive bone loss raises formidable challenges in total hip revision. The aim of this study was to evaluate the results of reconstruction using a cemented long-stem and massive structural allograft implanted in a filleted proximal femur, with and without the use of a trochanteric claw plate. Between 1988 and 2001, 44 revisions were performed in 42 patients. After a transtrochanteric approach, the femur was cut longitudinally. A long, cemented Charnley-type prosthesis was used, and flaps of the residual femur were folded around the allograft. The greater trochanter was reinserted with wires in all revisions, and with both wires and a claw plate in 20 revisions. Mean follow-up was 7.15 years (range: 3–16); seven patients, died and four were lost to follow-up. The follow-up exceeded five years in 34 patients. The major complication was nonunion of the greater trochanter, which occurred in 25 cases. Six dislocations, one recurrence of infection, two mechanical loosening, and two fractures below the stem were also recorded. The use of a trochanteric claw plate significantly improved final hip stability, even in patients with nonunion. Femoral reconstruction with a massive structural allograft is reliable and long-lived, and serious complications and long-term resorption are uncommon. The use of a trochanteric claw plate significantly improves final hip stability. Level of evidence: Therapeutic study, level III (retrospective comparative study). PMID:18008098

    The differential diagnosis of hip pain is broad and includes intra-articular pathology, extra-articular pathology, and mimickers, including the joints of the pelvic ring. With the current advancements in hip arthroscopy, more patients are being evaluated for hip pain. In recent years, our understanding of the functional anatomy around the hip has improved. In addition, because of advancements in magnetic resonance imaging, the diagnosis of soft tissue causes of hip pain has improved. All of these advances have broadened the differential diagnosis of pain around the hip joint and improved the treatment of these problems. In this review, we discuss the causes of intra-articular hip pain that can be addressed arthroscopically: labral tears, loose bodies, femoroacetabular impingement, capsular laxity, tears of the ligamentum teres, and chondral damage. Extra-articular diagnoses that can be managed arthroscopically are also discussed, including: iliopsoas tendonitis, "internal" snapping hip, "external" snapping hip, iliotibial band and greater trochanteric bursitis, and gluteal tendon injury. Finally, we discuss extra-articular causes of hip pain that are often managed nonoperatively or in an open fashion: femoral neck stress fracture, adductor strain, piriformis syndrome, sacroiliac joint pain, athletic pubalgia, "sports hernia," "Gilmore's groin," and osteitis pubis.

    Episacral lipoma is a small, tender subcutaneous nodule primarily occurring over the posterior iliac crest. Episacral lipoma is a significant and treatable cause of acute and chronic low back pain. Episacral lipoma occurs as a result of tears in the thoracodorsal fascia and subsequent herniation of a portion of the underlying dorsal fat pad through the tear. This clinical entity is common, and recognition is simple. The presence of a painful nodule with disappearance of pain after injection with anaesthetic, is diagnostic. Medication and physical therapy may not be effective. Local injection of the nodule with a solution of anaesthetic and steroid is effective in treating the episacral lipoma. Here we describe 2 patients with painful nodules over the posterior iliac crest. One patient complained of severe lower back pain radiating to the left lower extremity and this patient subsequently underwent disc operation. The other patient had been treated for greater trochanteric pain syndrome. In both patients, symptoms appeared to be relieved by local injection of anaesthetic and steroid. Episacral lipoma should be considered during diagnostic workup and in differential diagnosis of acute and chronic low back pain.

    Summary Background the aim of this study was to measure the effects of high volume image-guided injections and structured rehabilitation (HVIGI&SR) for greater trochanter pain syndrome (GTPS). Methods 31 consecutive subjects were recruited (23 retrospectively; 8 prospectively) over 5 months. GTPS was diagnosed based on history and examination findings, alongside radiological examination. The HVI-GI used a 22-gauge spinal needle to administer 10ml of 0.5% Marcaine and 50 mg hydrocortisone just deep to the periosteum underlying the gluteal tendon insertion under ultrasound guidance, followed by structured rehabilitation. A visual analogue scale (VAS) for pain was used as the main outcome measure. Results the mean VAS improved from 81.7 mm (±17.6) to 42.3 mm (±28.3), (p<0.05) in the prospective subjects at a mean of 6 weeks, considered clinically significant. In the retrospective subjects the mean VAS had improved from 74.6 (±10.9) mm to 38.2(±31.2) mm at two weeks (p<0.01) and 31.3 (±27.6) mm at the final time point, a mean of 60 weeks (p<0.01). The Hip and Groin Outcome Score in the prospective group showed a non-significant increase from 173.2 to 296.1 (p=0.12). Conclusion HVIGI&SR should be considered when short- and medium-term pain-relieving treatment for GTPS is required. Controlled studies are warranted to fully establish effectiveness, and assess long term effects. Level of evidence case series. PMID:26261785

    Objective this was an epidemiological study on trochanteric bursitis at the time of performing total hip arthroplasty. Methods sixty-two sequential patients who underwent total hip arthroplasty due to osteoarthrosis, without any previous history of trochanteric bursitis, were evaluated. The bursas were collected and evaluated histologically. Results there were 35 female patients (56.5%) and 27 male patients (43.5%), with a mean age of 65 years (±11). Trochanteric bursitis was conformed histologically in nine patients (14.5%), of whom six were female (66.7%) and three were male (33.3%). Conclusions 14.5% of the bursas analyzed presented inflammation at the time that the primary total hip arthroplasty due to osteoarthrosis was performed, and the majority of the cases of bursitis were detected in female patients.

    The purpose of this study was to investigate the influence of lateral muscle loading on the stress/strain distributions of the trochanteric Gamma nail (TGN) fixation within the healed, trochanteric and subtrochanteric femoral fractures by means of a finite element method. The effect of three muscle groups, the abductors (ABD), the vastus lateralis (VL) and the iliotibial band (ITB), were investigated. The analytical results showed that addition of lateral muscle forces, iliotibial band and vastus lateralis, produced compensation of forces and reduction of bending moments in the bone and in the trochanteric Gamma nail especially in the lateral aspect. The iliotibial band produced a higher impact as compared to the vastus lateralis. Therefore in the finite element analysis of the proximal femur with the trochanteric Gamma nail fracture fixation should include the lateral muscle forces to simulate load condition with maximal physiological relevance to the closed nailing technique.

    Back pain is a leading cause of disability. Previous research suggests that modifiable risk factors influence recovery from back pain, and practice guidelines recommend integrating such factors within primary care management. Toward this goal, a brief, multidimensional questionnaire, the STarT Back Tool, was designed to facilitate risk assessment by reducing the need to administer multiple, unidimensional questionnaires. However, aspects of this tool's clinical utility remain unaddressed. For instance, it is unclear whether this tool is responsive to treatment-related changes or whether clinically meaningful information is lost when it replaces multiple risk questionnaires. This study compared the responsiveness of the STarT Back Tool to its corresponding full-length measures, and evaluated its ability to detect clinically meaningful improvement. The study sample included 300 participants that consulted their doctor with disabling back pain. The STarT Back Tool and its reference standard questionnaires (disability, catastrophizing, fear, and depression) were administered at baseline and 4 months later. Regression analyses tested whether, after controlling for its reference standard questionnaires, the STarT Back Tool (independent variable) predicted treatment-related changes in global improvement, pain severity, disability, catastrophizing, fear, and depression (dependent variables). Receiver operating characteristic analyses determined the level of STarT Back change needed for clinically meaningful improvement. STarT Back scores predicted changes in all dependent variables except depression. Reductions in STarT Back scores predicted meaningful improvement on all dependent variables. These findings suggest that the STarT Back Tool, instead of multiple risk questionnaires, can be used to measure recovery from back pain. Implications for future research and clinical practice are discussed.

    Introduction Variation in the outcomes in RcTs comparing water-related methods and air insufflation during the insertion phase of colonoscopy raises challenging questions regarding the approach. This report reviews the impact of water exchange on the variation in attenuation of pain during colonoscopy by water-related methods. Methods Medline (2008 to 2011) searches, abstracts of the 2011 Digestive Disease Week (DDW) and personal communications were considered to identify RcTs that compared water-related methods and air insufflation to aid insertion of the colonoscope. Results: Since 2008 nine published and one submitted RcTs and five abstracts of RcTs presented at the 2011 DDW have been identified. Thirteen RcTs (nine published, one submitted and one abstract, n=1850) described reduction of pain score during or after colonoscopy (eleven reported statistical significance); the remaining reports described lower doses of medication used, or lower proportion of patients experiencing severe pain in colonoscopy performed with water-related methods compared with air insufflation (Tables 1 and 2). The water-related methods notably differ in the timing of removal of the infused water - predominantly during insertion (water exchange) versus predominantly during withdrawal (water immersion). Use of water exchange was consistently associated with a greater attenuation of pain score in patients who did not receive full sedation (Table 3). Conclusion The comparative data reveal that a greater attenuation of pain was associated with water exchange than water immersion during insertion. The intriguing results should be subjected to further evaluation by additional RcTs to elucidate the mechanism of the pain-alleviating impact of the water method. PMID:22163081

    Prevention of avascular complications is a primary aim. The ischemic insult to the femoral head provokes different types of morphologic deformities depending on its location. When the lateral part of the growth plate is affected, the head will be in valgus with a short neck, on the contrary, when the medial part is affected, a coxa vara occurs. The sooner the growth is stopped, the shorter the neck will be. Nevertheless, the greater trochanter will continue its growth and under certain conditions, will extend beyond the head. The Articulo-Trochanteric Distance is a measurement of the deformity which may be checked regularly. Early recognition permits prevention and adequate treatment. Treatment options include epiphysiodesis of the greater trochanter before the age of 8 to 10 years, trochanteric repositioning with osteotomy, and valgus osteotomy (Pauwels' Y-osteotomy).

    The concept of psoas impingement secondary to a tight or inflamed iliopsoas tendon causing impingement of the anterior labrum during hip extension has been suggested. The purpose of this study was to assess the relationship between the lesser trochanteric version (LTV) in symptomatic patients with psoas impingement as compared with asymptomatic hips. The femoral neck version (FNV) and LTV were evaluated on axial magnetic resonance imaging, as well as the angle between LTV and FNV. Data from 12 symptomatic patients and 250 asymptomatic patients were analysed. The mean, range and standard deviations were calculated. Independent t-tests were used to determine differences between groups. The lesser trochanteric retroversion was significantly increased in patients with psoas impingement as compared with asymptomatic hips (−31.1° SD ± 6.5 versus −24.2° ± 11.5, P < 0.05). The FNV (9° ± 8.8 versus 14.1° ± 10.7, P > 0.05) and the angle between FNV and LTV (40.2° ± 9.7 versus 38.3° ± 9.6, P > 0.05) were not significantly different between groups. In conclusion, the lesser trochanteric retroversion is significantly increased in patients with psoas impingement as compared with asymptomatic hips. PMID:27011834

    Background: The sliding screw-plate devices and cephalo-medullary nail devices have performed well in stable inter-trochanteric fractures in patients with reasonably good quality of bone. However, their suboptimal performance in comminuted fractures in the presence of osteoporotic bone has prompted many surgeons to consider bipolar hemiarthroplasty as the primary modality of management of comminuted inter-trochanteric fractures in elderly patients. However, long term stability of the hemiarthroplasty implant also may be compromised due to the presence of postero-medial bone loss at the area of the calcar. Materials and Methods: We have presented a simple and effective technique of calcar grafting by harvesting cortical bone strut from the neck of the fractured femur. A total of 34 patients with inter-trochanteric fractures of the femur were treated with calcar grafting. The mean age was 79.2 years. The graft was harvested from the calcar region of the head and neck fragment of the femur and wedged between the medial femoral cortex and medial edge of the prosthesis. The mean followup period was 54.5 months. Results: In 32 of 34 (94%) patients in our series, the calcar graft healed well without dislodgement. There was graft resorption in two patients associated with subsidence of the implant and loosening. Conclusion: Calcar grafting using this technique provides stability to the implant in the presence of comminution and incorporates well in the majority of patients. Donor site morbidity of graft harvesting is also avoided. PMID:26806966

    Giant cell arteritis, a large-sized vessel vasculitis, may be associated with musculoskeletal proximal (polymyalgia rheumatica) or distal manifestations. A 68-year-old woman, who had inflammatory pelvic girdle pain, was diagnosed with giant cell arteritis and was successfully treated with corticosteroids. The magnetic resonance imaging and ultrasonography revealed a bilateral bursitis and pelvic girdle enthesopathy. Bursitis is the main anatomic lesion occurring in polymyalgia rheumatica and can be underlined by ultrasonography.

    After trochanteric fractures, the rate of survival of old patients was best when treated by the Ender method: 15% died during 3 months following the fracture. The procedure is uneasy and an excellent radiologic technique is necessary. The position of the proximal end of the first nail in the femoral head is most important. Excessive external rotation was frequent, but little desabling. Secondary displacement of the nails toward the distal end occurred in 25% of the cases and was difficult to avoid but remained moderate. The procedure is indicated in old people with porotic bones. It should not be done in subtrochanteric fractures.

    Background Total hip arthroplasty with subtrochanteric shortening osteotomy is widely performed for high hip dislocation. However, suboptimal leg length discrepancy correction and nonunion of the osteotomy site remain concerns. Although total hip arthroplasty using trochanteric osteotomy without subtrochanteric osteotomy was introduced, cemented implants have been more commonly used than contemporary cementless implants in this procedure. We evaluated the long-term results of cementless total hip arthroplasty with trochanteric osteotomy without subtrochanteric osteotomy for high hip dislocation. Methods From 1990 to 2002, 27 cementless total hip arthroplasties using trochanteric osteotomy without subtrochanteric osteotomy were performed in 26 patients with Crowe III or IV high hip dislocation and a mean age of 36.4 ± 12.9 years. Seven ceramic-on-ceramic, 8 ceramic-on-polyethylene, 10 metal-on-polyethylene, and 2 metal-on-metal bearings were inserted. Mean follow-up was 15.1 ± 3.7 years. We retrospectively reviewed medical records and radiographic data and evaluated the clinical and radiological results including the Harris hip score, implant survival, correction of leg length discrepancy, and occurrence of complications. Results The mean Harris hip score and leg length discrepancy improved significantly from 73.3 to 94.9 points and from 4.3 cm to 1.0 cm, respectively. With revision for loosening set as the end point, implant survival rates at 10 and 15 years postoperatively were 96.0% and 90.9% for stems and 74.1% and 52.3% for cups. In 8 of 10 hips with the metal-on-polyethylene bearing and 4 of 8 hips with the ceramic-on-polyethylene bearing, revision surgery was performed for aseptic loosening. However, no revision was performed in hips with the ceramic-on-ceramic bearing or the metal-on-metal bearing. Implant survival was significantly different by the type of bearing surface. Two permanent neurologic complications occurred in patients with a limb lengthening

This entity has not been reported previously. Our patient was treated by hemi-arthroplasty and repair of the disrupted capsule, and achieved a good long-term functional result. The cause of this particular condition is discussed.

    Introduction Management of unstable intertrochanteric fractures have posed a unique challenge to orthopaedicians over years. Several surgical techniques and implants have been developed for the same. Fractures of the lateral wall have been considered as the major cause of femoral medialization after fixation by Dynamic Hip Screw (DHS). Studies have shown that supplementation of trochanteric stabilization plate reduces the incidence of femoral medialization. Aim To assess the radiological union and hip function after fixation of unstable intertrochanteric fractures with DHS and Trochanteric Stabilization Plate (TSP). Materials and Methods A prospective study was conducted with a total of 32 patients between age groups of 30-70 years with Evan Jensen unstable and very unstable type of intertrochanteric fractures, between August 2013 to March 2015 in the Department of Orthopaedics ARS Hospital, Tirupur, Tamil Nadu, India. They underwent open reduction and DHS and TSP fixation. They were started on full weight bearing mobilization on post op day three. They were reviewed at post-op weeks 3,6,12 and 24. Hip mobilization and rehabilitation exercises were instituted during course of reviews. Radiographs were taken to assess fracture union and hip function was evaluated during follow-ups. At the end of 24 weeks, degree of radiographic union was scored as per Radiological Union Score for Hip (RUSH). Hip function was scored with Harris hip score. Analyses were done using frequency and proportions. Chi-square tests were used to assess the test of association. Results Fifteen patients had RUSH scores between 10-20 and 17 patients had scores between 20-30 points. RUSH score had mean of 21.03+/- 2.132 points. 9 of 32 patients had excellent results as per Harris hip score, 10 had good, nine had fair and four had poor. On comparison of Harris hip score with RUSH score: Interval between 10-20 points, of 15 patients; two had excellent results, five had good, five had fair and three

    This study compared the sliding characteristics of three lag screw designs used with trochanteric nails and determined the effects of lubrication on sliding. They were tested by an established method to measure initiation and ease of lag screw sliding. These tests were then repeated with calf serum lubrication. There were significant differences (p < 0.05) between the loads required to initiate lag screw sliding that appeared to be related to design. Screw sliding was similar for all three designs; however, the presence of lag screw locking slots affected sliding in that region. Lubrication did not affect either parameter. Lag screw design aspects, such as diameter and, particularly, surface finish, affect sliding. Due to the small contact area between the lag screw and nail creating high interface stresses, lubrication had no effect on lag screw sliding.

The patients were evaluated clinically, radiologically and functionally one week, two weeks, one month, two months, six months and one year after the operation. Results: The clinical complications comprised five cases of death, one case of calcaneal ulcer, one case of acute arterial obstruction and two cases of deep vein thrombosis. The radiographic evaluation showed that the mean cervicodiaphyseal angle in the immediate postoperative period was 132.5°. The mean tip-apex index was 22.8 mm. After one year, the mean cervicodiaphyseal angle was 131.7°. Fracture consolidation was seen in all the patients six months after the operation, except in one case that presented cut-out. There were no cases of fracture below the implant. The functional evaluation using the Harris score after one year showed a mean of 69.3 points. The evaluation of walking progress showed that after one year, 40.6% of the patients had the same ability to walk that they had before the fracture. The visual analogue pain scale showed that a significant decrease in pain complaints occurred, going from 5.19 in the first week to 2.25 after 1 year. Conclusion: Osteosynthesis using a cephalomedullary nail resulted in low rates of clinical and mechanical complications and adequate functional outcomes. PMID:27027025

    Tuberculous trochanteric bursitis (TTB) is a rare condition that accounts for 1% of musculoskeletal tuberculosis cases. Extrapulmonary TB is usually diagnosed late because of reduced diagnostic suspicion, particularly in the absence of signs of systemic infection. Herein, we report a case of right hip pain that was misdiagnosed as ankylosing spondylitis. The patient had a history of inflammatory back pain with morning stiffness. However, HLA-B27 was negative. Sacroiliac magnetic resonance imaging (MRI) revealed a giant multiloculated collection (27×16×10 cm). Percutaneous drainage was performed and Mycobacterium tuberculosis was observed in fluid culture. The patient was treated by drainage along with antituberculosis therapy. After 1 year of antituberculosis therapy, control MRI revealed total resolution of the large fluid collection. It is important to emphasize that fever or general symptoms are absent in patients with TTB, as observed in the present case. In endemic countries, TTB should be kept in mind in the differential diagnosis of a patient presenting with chronic hip pain without fever, weight loss, and constitutional symptoms.

  15. Increase in the incidence of cervical and trochanteric fractures of the proximal femur in Niigata Prefecture, Japan.

    This study aimed to determine the incidence of cervical and trochanteric fractures of the proximal femur in 1994 in Niigata Prefecture, Japan, and to compare this incidence with those previously reported in Niigata in 1985, 1987, and 1989. We visited all hospitals within Niigata Prefecture having an orthopedic department and reviewed the medical records and radiographs of all patients who sustained such fractures in 1994. The population of Niigata Prefecture was determined in 1994 to be 2,483,879 (1,205,151 males and 1,278,728 females). The population over 65 years of age was 428,795 (172,788 males and 256,007 females), representing 17.3% of the total population. In 1994, there were 1,468 cervical or trochanteric fractures in 378 males and 1,090 females, with a male-to-female ratio of 1:2.9. The incidence of these fractures in persons over 65 years of age was 304 fractures per 100,000 population per year. Of 528 cervical and 940 trochanteric fractures, the latter accounted for 64% of the total number. The age-specific incidence of the fractures in Niigata exhibited an exponential increase with age, similar to those reported in Sweden and the United States. However, the incidence was lower than in those countries. When comparing the number of cervical and trochanteric fractures in 1994 with the numbers reported in 1985, 1987, and 1989, it is evident that the overall number and incidence of these fractures has been increasing over this period. Even if the difference of the age-specific population among these years is adjusted, the fractures have been increasing.

  16. Wiring Techniques for the Fixation of Trochanteric Fragments during Bipolar Hemiarthroplasty for Femoral Intertrochanteric Fracture: Clinical Study and Technical Note

    Purpose Femoral intertrochanteric fractures are common in the elderly. Appropriate surgical fixation of trochanteric fracture fragments can restore normal anatomical structure and ambulation, and can aid in the recovery of biomechanical function of the hip. We evaluated clinical outcomes of bipolar hemiarthroplasty using a wiring technique for trochanteric fracture fragment fixation. Materials and Methods From September 2006 to February 2015, a total of 260 cases underwent simultaneous bipolar hemiarthroplasty and wire fixation. A total of 65 patients (69 hips) with an average age of 78 years and more than one year of follow-up was included in the study. Using pre-, postoperative and follow-up radiograms, we evaluated wire fixation failure and also assessed changes in walking ability. Results Loosening or osteolysis around the stem was not observed; however, we did observe bone growth around the stem (54 cases), cortical hypertrophy (6 cases), a wide range of sclerotic lines but no stem subsidence (1 case), wire breakage (9 cases), and fracture fragment migration with no significant functional deficiency (2 cases). Conclusion Our study showed that additional wiring for trochanteric fracture fragment fixation following bipolar hemiarthroplasty can help restore normal anatomy. The added stability results in faster rehabilitation, and good clinical and radiographic outcomes. We recommend this procedure in this type of fracture. PMID:28316962

    Hispanic adults experience significant pain, but little is known about their pain during hospitalization. The purpose of this research was to describe Hispanic inpatients' pain intensity and compare their pain intensity with that of non-Hispanic patients. A post hoc descriptive design was used to examine 1,466 Hispanic inpatients' medical records (63.2% English speakers) and 12,977 non-Hispanic inpatients' medical records from one hospital for 2012. Mean documented pain intensity was mild for both Hispanic and non-Hispanic inpatients. Pain intensity was greater for English-speaking Hispanic patients than Spanish speakers. The odds of being documented with moderate or greater pain intensity decreased 30% for Spanish-speaking patients. Greater pain intensity documented for English-speaking Hispanic inpatients suggests underreporting of pain intensity by Spanish-speaking patients. Practitioners should use interpreter services when assessing and treating pain with patients who speak languages different from the practitioners' language(s).

    Healthy children are often required to repeatedly undergo painful medical procedures (eg, immunizations). Although memory is often implicated in children's reactions to future pain, there is a dearth of research directly examining the relationship between the 2. The current study investigated the influence of children's memories for a novel pain stimulus on their subsequent pain experience. One hundred ten healthy children (60 boys) between the ages of 8 and 12 years completed a laboratory pain task and provided pain ratings. Two weeks later, children provided pain ratings based on their memories as well as their expectancies about future pain. One month following the initial laboratory visit, children again completed the pain task and provided pain ratings. Results showed that children's memory of pain intensity was a better predictor of subsequent pain reporting than their actual initial reporting of pain intensity, and mediated the relationship between initial and subsequent pain reporting. Children who had negatively estimated pain memories developed expectations of greater pain prior to a subsequent pain experience and showed greater increases in pain ratings over time than children who had accurate or positively estimated pain memories. These findings highlight the influence of pain memories on healthy children's expectations of future pain and subsequent pain experiences and extend predictive models of subsequent pain reporting.

  19. Evaluating the patient with low back pain.

    Shaikh, Maliha; Östör, Andrew J K

    2015-12-01

    In the UK, low back pain is the most common cause of disability in young adults and every year 6-9% of adults consult their GP about back pain. A thorough history and examination is required to exclude an alternative diagnosis, such as pain arising from the hip or trochanteric bursa and to categorise patients as having: serious spinal pathology, nerve root/radicular pain or non-specific back pain. Inflammatory back pain is often missed, particularly in the early stages when examination may be normal. The primary features are pain arising in patients under 40, thoracolumbar or sacroiliac pain and alternating buttock pain. Stiffness in the early morning and after rest is a hallmark of inflammatory back pain. There may also be peripheral joint involvement with evidence of inflammatory arthritis as well as extra-articular manifestations such as iritis, psoriasis and colitis. Sphincter disturbance leading to loss of bladder or bowel control should also be explored as it is a sign of spinal cord compression or cauda equina syndrome. Both of these are neurosurgical emergencies and need urgent referral for further investigation and possible intervention. The majority of patients with low back pain can be managed in primary care as the pain will usually be self-limiting. Patients with suspected inflammatory back pain should be referred to rheumatology as soon as possible in order to institute early management and prevent long-term deformity and disability. Patients with suspected serious spinal pathology should be referred urgently for further investigation. Red flag symptoms should raise concerns regarding a possible sinister cause such as malignancy and more than one red flag mandates urgent further investigation.

  20. Biomechanical analysis of the cephalomedullary nail versus the trochanteric stabilizing plate for unstable intertrochanteric femur fractures.

    Unstable intertrochanteric fractures are commonly treated with a cephalomedullary nail due to high failure rates with a sliding hip screw. The Omega3 Trochanteric Stabilizing Plate is a relatively new device that functions like a modified sliding hip screw with a proximal extension; however, its mechanical properties have not been evaluated. This study biomechanically compared a cephalomedullary nail, that is, Gamma3 Nail against the Omega3 plate. Unstable intertrochanteric fractures were created in 24 artificial femurs. Experimental groups were as follows: Nail (i.e. Gamma3 Nail) (n = 8), Plate A (i.e. Omega3 plate with four distal non-locking screws and no proximal locking screws) (n = 8), Plate B (i.e. Plate A plus five proximal locking screws) (n = 8), Plate C (i.e. Omega3 plate with three distal locking screws and no proximal locking screws) (n = 8), and Plate D (i.e. Plate C plus five proximal locking screws) (n = 8). All specimens were stiffness tested, while the Nail and Plate D groups were also strength tested. For lateral bending, Plate B was less stiff than the Nail (p = 0.001) and Plate A (p = 0.009). For torsion, Plate A was less stiff than Plate D (p = 0.020). For axial compression, the Nail was less stiff than Plate A (p = 0.036) and Plate B (p = 0.008). Axial strength for the Nail (5014 ± 308 N) was 66% higher than the Plate D construct (2940 ± 411 N) (p < 0.001). All Nails failed by partial or complete cutout through the femoral head and neck, but Plate D failed by varus collapse and deformation of the lag screw. When the cephalomedullary nail is clinically contra-indicated, this study supports the use of the Omega3 plate, since it had similar stiffness in three test modes to the Gamma3 Nail, but had lower strength. Stability of Omega3 plate constructs was not improved with locked fixation proximally or distally.

  6. Neurological diseases and pain

    PubMed Central

    2012-01-01

    Chronic pain is a frequent component of many neurological disorders, affecting 20–40% of patients for many primary neurological diseases. These diseases result from a wide range of pathophysiologies including traumatic injury to the central nervous system, neurodegeneration and neuroinflammation, and exploring the aetiology of pain in these disorders is an opportunity to achieve new insight into pain processing. Whether pain originates in the central or peripheral nervous system, it frequently becomes centralized through maladaptive responses within the central nervous system that can profoundly alter brain systems and thereby behaviour (e.g. depression). Chronic pain should thus be considered a brain disease in which alterations in neural networks affect multiple aspects of brain function, structure and chemistry. The study and treatment of this disease is greatly complicated by the lack of objective measures for either the symptoms or the underlying mechanisms of chronic pain. In pain associated with neurological disease, it is sometimes difficult to obtain even a subjective evaluation of pain, as is the case for patients in a vegetative state or end-stage Alzheimer's disease. It is critical that neurologists become more involved in chronic pain treatment and research (already significant in the fields of migraine and peripheral neuropathies). To achieve this goal, greater efforts are needed to enhance training for neurologists in pain treatment and promote greater interest in the field. This review describes examples of pain in different neurological diseases including primary neurological pain conditions, discusses the therapeutic potential of brain-targeted therapies and highlights the need for objective measures of pain.

    2011-01-01

    Objectives Our primary goals were to determine whether pre-existing fear of pain and pain sensitivity contributed to post-exercise pain intensity. Methods Delayed onset muscle pain was induced in the trunk extensors of 60 healthy volunteers using an exercise paradigm. Levels of fear of pain and experimental pain sensitivity were measured before exercise. Pain intensity in the low back was collected at 24 and 48 hours post-exercise. Participants were grouped based on pain intensity. Group membership was used as the dependent variable in separate regression models for 24 and 48 hours. Predictor variables included fear, pain sensitivity, torque lost during the exercise protocol, and demographic variables. Results The final models predicting whether a participant reported clinically meaningful pain intensity at 24 hours only included baseline fear of pain at each level of pain intensity tested. The final model at 48 hours included average baseline pain sensitivity and the loss of muscle performance during the exercise protocol for one level of pain intensity tested (greater than 35mm out of 100). Discussion Combined, these findings suggest that the initial reports of pain after injury maybe more strongly influenced by fear while the inflammatory process and pain sensitivity may play a larger role for later pain intensity reports.

    The proximal femoral nail antirotation is a new generation of intramedullary device for the treatment of trochanteric femoral fractures, having a helical blade rather than a screw for suggested better purchase in osteoporotic bone. However, it is not free of complications. Few reports are available on postoperative perforation of the helical blade through the femoral head as a unique complication of proximal femoral nail antirotation. We report a 79-year-old woman with acetabular perforation after migration of the helical blade through the femoral head after an unstable trochanteric fracture, which was fixed with a proximal femoral nail antirotation.

    2009-10-01

    This article presents a simple technique for fascia lata lengthening that is less aggressive, can be performed under local anaesthetic with little morbidity and disability, and has excellent results. Eleven patients (13 hips) were enrolled in this study. Mean age was 54.6 years, there was one man and ten women. Outcomes were assessed by using a visual analog pain scale, Harris hip score and Lickert scale (satisfaction). There was a mean follow-up time of 43 months (range 15-84). All patients were scored by the Harris hip scale with a mean improvement from 61 (range 48-77) to 91 (range 76-95) after surgery. The mean visual analogue scale (VAS) score improved from 83 (range 60-99) to 13 (range 0-70). We had 12 of 13 patients reporting a good result. Mean surgical time was 15 min, and only one seroma was reported as a complication. No inpatient management was needed. In conclusion, distal "Z" lengthening of the fascia lata appears to be a good alternative for treatment of this condition.

  10. Greater trochanter apophysitis in the adolescent athlete.

    2015-05-01

    Lower limb traction apophysitis is common in young athletes, occurring at sites such as the tibial tubercle (Osgood-Schlatter disease) and distal patella (Sinding-Larsen-Johansson disease). Around the hip, iliac apophysitis is well recognized, but no cases of greater trochanter apophysitis have previously been reported. We describe the case of a 15-year-old male basketball player with a 2-month history of the right hip pain and significant functional limitation. X-rays revealed widening of the greater trochanter apophysis with subchondral sclerosis, consistent with a diagnosis of traction apophysitis. The patient was treated with a period of relative rest and anti-inflammatory medication. He gradually returned to full athletic activity, including basketball, without recurrence of pain or limitation. We describe the first reported case of traction apophysitis of the greater trochanter. The unique muscular anatomy of this apophysis with balanced forces explains the rarity of this condition. If encountered, rest and activity modification is the recommended treatment.

    Primary or idiopathic greater omental torsion remains a rare cause of acute surgical abdomen in adults and children. The aetiology is as yet unknown and the treatment of choice, once diagnosis is established, is resection of the torted omentum. We report our experience with three such cases encountered over the last five years, two of which were diagnosed and subsequently managed laparoscopically. The performance of diagnostic laparoscopy for acute abdominal pain of an undetermined origin may lead to an increased detection of this condition and subsequent therapeutic intervention.

  13. Foetal pain?

    PubMed

    Derbyshire, Stuart W G

    2010-10-01

    The majority of commentary on foetal pain has looked at the maturation of neural pathways to decide a lower age limit for foetal pain. This approach is sensible because there must be a minimal necessary neural development that makes pain possible. Very broadly, it is generally agreed that the minimal necessary neural pathways for pain are in place by 24 weeks gestation. Arguments remain, however, as to the possibility of foetal pain before or after 24 weeks. Some argue that the foetus can feel pain earlier than 24 weeks because pain can be supported by subcortical structures. Others argue that the foetus cannot feel pain at any stage because it is maintained in a state of sedation in the womb and lacks further neural and conceptual development necessary for pain. Much of this argument rests on the definition of terms such as 'wakefulness' and 'pain'. If a behavioural and neural reaction to a noxious stimulus is considered sufficient for pain, then pain is possible from 24 weeks and probably much earlier. If a conceptual subjectivity is considered necessary for pain, however, then pain is not possible at any gestational age. Regardless of how pain is defined, it is clear that pain for conceptual beings is qualitatively different than pain for non-conceptual beings. It is therefore a mistake to draw an equivalence between foetal pain and pain in the older infant or adult.

  2. Why Social Pain Can Live on: Different Neural Mechanisms Are Associated with Reliving Social and Physical Pain

    PubMed Central

    Meyer, Meghan L.; Williams, Kipling D.; Eisenberger, Naomi I.

    2015-01-01

    Although social and physical pain recruit overlapping neural activity in regions associated with the affective component of pain, the two pains can diverge in their phenomenology. Most notably, feelings of social pain can be re-experienced or “relived,” even when the painful episode has long passed, whereas feelings of physical pain cannot be easily relived once the painful episode subsides. Here, we observed that reliving social (vs. physical) pain led to greater self-reported re-experienced pain and greater activity in affective pain regions (dorsal anterior cingulate cortex and anterior insula). Moreover, the degree of relived pain correlated positively with affective pain system activity. In contrast, reliving physical (vs. social) pain led to greater activity in the sensory-discriminative pain system (primary and secondary somatosensory cortex and posterior insula), which did not correlate with relived pain. Preferential engagement of these different pain mechanisms may reflect the use of different top-down neurocognitive pathways to elicit the pain. Social pain reliving recruited dorsomedial prefrontal cortex, often associated with mental state processing, which functionally correlated with affective pain system responses. In contrast, physical pain reliving recruited inferior frontal gyrus, known to be involved in body state processing, which functionally correlated with activation in the sensory pain system. These results update the physical-social pain overlap hypothesis: while overlapping mechanisms support live social and physical pain, distinct mechanisms guide internally-generated pain.

  4. Autologous Fat Grafting as a Last Resort for Unsustainable Pain in a Woman with Multiple Osteochondromas

    2017-01-01

    Multiple osteochondromas (MO) is characterized by the formation of osteochondromas throughout the entire body. Although the evidence regarding its pathogenesis is well understood, no curative treatment for the disorder is available. Patients can be treated symptomatically by surgical removal of painful osteochondromas. Unfortunately, some patients still suffer from severe pain, even after surgery. We report on a case concerning a 48-year-old woman with a history of MO who presented with persistent pain after surgical removal of a symptomatic osteochondroma of the left scapula and multiple symptomatic osteochondromas of the left foot and trochanteric region. Several interventions to reduce the pain did not have any lasting effect. Subsequently, she was treated with autologous fat grafting (AFG). After each session she was pain-free for at least one year and reported only partial recurrence of the pain. This is the first case report describing AFG for the treatment of pain after both surgical removal of an osteochondroma and symptomatic osteochondromas in a patient suffering MO with promising results. The treatment is more effective and clearly continues to remain active longer than injection therapy or pain medication. Future studies are necessary to confirm our results. PMID:28352606

    We studied the effect of implantation of self-reinforced polyglycolic acid (SR-PGA) screws through the greater trochanter in rabbits. 15 rabbits aged 10 weeks had an SR-PGA screw inserted through the left trochanter physis. A similar drilling was made through the right greater trochanter without screw implantation. The animals were assigned to 3 groups of 5, and were killed after 1, 2 or 3 months. Radiographs of both femurs were obtained monthly and the articulo-trochanteric distance and the neck-shaft angle were measured. After killing the animals, a histological study was performed. The drilling on the right trochanter generated a bony bridge in all the animals. The SR-PGA screws did not give rise to an epiphysiodesis. The progressive peripheral degradation of the implants gave rise to the formation of only modest bridges, which were smaller in size than those observed in the control trochanter. Our findings suggest that absorbable PGA screws implanted through a growth plate cause only minor bone formation and no epiphyseodesis.

  6. Relationship of child perceptions of maternal pain to children's laboratory and non-laboratory pain.

    2008-01-01

    Previous research has established links between parent and child pain. However, little is known about sex-specific parent-child pain relationships in a nonclinical population. A sample of 186 children aged eight to 18 years (49% female) provided information on maternal and self bodily pain, assessed by asking children about the presence and location of bodily pain experienced. Children also completed three laboratory pain tasks and reported on cold pressor pain intensity, pressure pain intensity and heat pain intensity. The presence of child-reported maternal pain was consistently correlated with daughters' bodily and laboratory pain, but not with sons' pain in bivariate analyses. Multivariate analyses controlling for child age and maternal psychological distress indicated that children of mothers with bodily pain reported more total bodily pain sites as well as greater pressure and cold pain intensity, relative to children of mothers without bodily pain. For cold pain intensity, these results differed for boys versus girls, in that daughters reporting maternal pain evidenced significantly higher cold pain intensity compared with daughters not reporting maternal pain. No such differences were found for boys. The findings suggest that children's perceptions of maternal pain may play a role in influencing children's own experience of pain, and that maternal pain models may affect boys and girls differently.

We have a greater appreciation for the complex nature of pain and that it can develop into a disease in itself. As such, we need more efforts on prevention of chronic pain and for interdisciplinary approaches. For precision pain medicine to be successful, we need to link learning health systems with pain biomarkers (eg, genomics, proteomics, patient reported outcomes, brain markers) and its treatment.

    BACKGROUND: Extant research comparing laboratory pain responses of children with chronic pain with healthy controls is mixed, with some studies indicating lower pain responsivity for controls and others showing no differences. Few studies have included different pain modalities or assessment protocols. OBJECTIVES: To compare pain responses among 26 children (18 girls) with chronic pain and matched controls (mean age 14.8 years), to laboratory tasks involving thermal heat, pressure and cold pain. Responses to cold pain were assessed using two different protocols: an initial trial of unspecified duration and a second trial of specified duration. METHODS: Four trials of pressure pain and of thermal heat pain stimuli, all of unspecified duration, were administered, as well as the two cold pain trials. Heart rate and blood pressure were assessed at baseline and after completion of the pain tasks. RESULTS: Pain tolerance and pain intensity did not differ between children with chronic pain and controls for the unspecified trials. For the specified cold pressor trial, 92% of children with chronic pain completed the entire trial compared with only 61.5% of controls. Children with chronic pain exhibited a trend toward higher baseline and postsession heart rate and reported more anxiety and depression symptoms compared with control children. CONCLUSIONS: Contextual factors related to the fixed trial may have exerted a greater influence on pain tolerance in children with chronic pain relative to controls. Children with chronic pain demonstrated a tendency toward increased arousal in anticipation of and following pain induction compared with controls. PMID:22518373

  11. Pain after hip arthroplasty managed by Brennan Healing Science.

    A case is presented illustrating the potential effect of Brennan Healing Science on pain following hip arthroplasty for avascular necrosis. A 54-year-old woman experienced anterior groin pain, numbness at the bottom of her foot, and occasional grinding at her hip 22 years after right total hip arthroplasty secondary to avascular necrosis. X-ray films showed signs of osteolysis behind the acetabular cup and asymmetric decreased polyethylene thickness of the acetabular prosthetic. Her orthopedic surgeon advised the patient to follow up every 6-9 months to avoid catastrophic failure of the implant, with plans for surgical revision to be scheduled at the next appointment. The patient sought alternative treatment to avoid an invasive procedure. On presentation, the patient had difficulty walking up the stairs into the treatment room due to pain which she rated a 9/10. She found it painful to rotate, flex, extend her hip, or to sit. Hands-on healing techniques based on the Brennan Healing Science method were initiated, starting at the feet, balancing the energy, and working the way up the joints. Once the work at the hip was completed, the hands-on techniques continued up the centerline of the body and the healing was brought to a close. On completion of a 60-minute healing, the patient was able to stand freely and rated her pain as a 4/10. Flexion, extension, and rotation at the hip were no longer distressing. She was able to walk up and down stairs without distress and denied instability, bursitis, or trochanteric or iliopsoas pain or swelling. Repeat X-rays showed decrease in bone spurs and no hardware problem, and her orthopedic surgeon recommended follow-up after 2 years. It is suggested that Brennan Healing Science techniques could play an effective and cost-efficient role in the treatment of pain following hip arthroplasty.

    Sexual pain is an underrecognized and poorly treated constellation of disorders that significantly impact affected women and their partners. Recognized as a form of chronic pain, sexual pain disorders are heterogeneous and include dyspareunia (superficial and deep), vaginismus, vulvodynia, vestibulitis, and noncoital sexual pain disorder. Women too often tolerate pain in the belief that this will meet their partners' needs. This article provides a review of the terminology and definition of the condition, theories on the pathophysiology, diagnostic considerations, and recommendations on the management of female sexual pain.

The etiology of the temporomandibular joint pain is enigmatic, no single etiological factor is regarded as the cause. Its distribution is also not confined to a single area. This article presents the basic etiologic factors, its epidemiology, distribution of pain, classification of patients and the psychosocial behavior of patients suffering with temporomandibular pain. As overwhelming majority of medical and dental conditions/issues related to etiology of temporomandibular pain in patients have traditionally been presented and interpreted from the clinician's point of view.

    2016-01-01

    Although clinical models have traditionally defined pain by its consequences for the behavior and internal states of the sufferer, recent evidence has highlighted the importance of examining pain in the context of the broader social environment. Neuroscience research has highlighted commonalities of neural pathways connecting the experience of physical and social pain, suggesting a substantial overlap between these phenomena. Further, interpersonal ties, support and aspects of the social environment can impair or promote effective adaptation to chronic pain through changes in pain perception, coping and emotional states. The current paper reviews the role of social factors in extant psychological interventions for chronic pain, and discusses how greater attention to these factors may inform future research and clinical care.

    Chronic Pain extracts a "penalty" on society now estimated to be well in excess of $100 million per year. The "penalty" that Chronic Pain extracts from its victims is incalculable. Chronic Pain is a major component of Temporomandibular Disorders. The current neurological theory of the mechanism of chronic TMD pain is explored along with the current modes of treatment. Pharmacological management of Chronic Pain in a clinical setting is outlined. Dentists are involved in pain management on a daily basis. Dentists treat pain both prophylacticly and in response to specific patient symptoms. Most dental treatment involves some type of pain management. We, dentists, have become very adept at managing acute pain. We have much greater difficulty managing chronic pain. The word "pain" derives from the Greek word for penalty, and appeared to them to be a "penalty" inflicted by the gods. In 1984, Bonica estimated that one-third of all Americans suffered from some kind of chronic pain at a "penalty" to society of $65 Billion annually in medical expenses and lost wages and productivity. This figure is certainly much greater now. Chronic pain can be a very complex problem that can require a multidisciplinary approach to treatment. Chronic pain in the dental setting is most frequetly caused by prolonged Temporomandibular Disorders.

    In the Greater Yellowstone Area, free-ranging bison occur in Jackson Hole, Wyoming, and Yellowstone National Park. The Yellowstone population is discussed, with emphasis on changes in numbers from approximately 400 in 1968 to about 3500 now. Major influences for change initially were natural; more recently the winter road system used by snowmobiles appeared to be the dominant factor. The situation is in a state of flux. Interagency planning is in progress to address management alternatives for conflicts outside the park.

  8. Ion channel therapeutics for pain

    2015-01-01

    Pain is a complex disease which can progress into a debilitating condition. The effective treatment of pain remains a challenge as current therapies often lack the desired level of efficacy or tolerability. One therapeutic avenue, the modulation of ion channel signaling by small molecules, has shown the ability to treat pain. However, of the 215 ion channels that exist in the human genome, with 85 ion channels having a strong literature link to pain, only a small number of these channels have been successfully drugged for pain. The focus of future research will be to fully explore the possibilities surrounding these unexplored ion channels. Toward this end, a greater understanding of ion channel modulation will be the greatest tool we have in developing the next generation of drugs for the treatment of pain. PMID:26218246

    Previous research suggests that for people living with chronic pain, pain expectancy can undermine access to adaptive resources and functioning. We tested and replicated the unique effect of pain expectancy on subsequent pain through 2 daily diary studies. We also extended previous findings by examining cognitive and affective antecedents of pain expectancy and the consequences of pain expectancy for daily social enjoyment and stress. In study 1, 231 individuals with rheumatoid arthritis completed 30 end-of-day diaries. Results of multilevel structural equation model showed that controlling for today's pain, pain expectancy predicted next day pain. In study 2, diary assessments of affective, cognitive, and social factors were collected during the morning, afternoon, and evening for 21 days from a sample of 220 individuals with fibromyalgia. Results showed that both positive affect and the extent to which pain interfered with daily activities in the afternoon predicted evening pain expectancy in the expected direction. However, negative affect and pain coping efficacy were not associated with pain expectancy. Consistent with study 1, more than usual evening pain expectancy was related to greater next morning pain. We also found that next morning pain predicted next afternoon social enjoyment but not social stress. The findings of these 2 studies point to the importance of promoting positive affect and reducing pain expectancy as a way of decreasing the detrimental effect of chronic pain on enjoyable social experiences.

  10. In vitro comparison of resistance to implant failure in unstable trochanteric fractures fixed with intramedullary single screw versus double screw device

    Background: The purpose of this study was to compare the resistance of intramedullary single screw device (Gamma nail) and double screw device proximal femoral nail (PFN) in unstable trochanteric fractures in terms of the number of cycles sustained, subsidence and implant failure in an axial loading test in cadaveric femora. Materials and Methods: The study was conducted on 18 dry cadaveric femoral specimens, 9 of these were implanted with a Gamma nail and 9 with PFN. There was no significant difference found in average dual energy X-ray absorptiometry value between both groups. The construct was made unstable (AO type 31A3.3) by removing a standard sized posteromedial wedge. These were tested on a cyclic physiological loading machine at 1 cycle/s with a load of 200 kg. The test was observed for 50,000 loading cycles or until implant failure, whichever occurred earlier. Peak displacements were measured and analysis was done to determine construct stiffness and gap micromotion in axial loading. Result: It was observed that there was statistically significant difference in terms of displacement at the fracture gap and overall construct stiffness of specimens of both groups. PFN construct group showed a mean subsidence of 1.02 mm and Gamma nail construct group showed mean subsidence of 2.36 mm after cycling. The average stiffness of Gamma nail group was 62.8 ± 8.4 N/mm which was significantly lower than average stiffness of the PFN group (80.4 ± 5.9 N/mm) (P = 0.03). In fatigue testing, 1 out of 9 PFN bone construct failed, while 5 of 9 Gamma nail bone construct failed. Conclusion: When considering micromotion (subsidence) and incidence of implant/screw failure, double screw device (PFN) had statistically significant lower micromotion across the fracture gap with axial compression and lower incidence of implant failure. Hence, double screw device (PFN) construct had higher stability compared to single screw device (GN) in an unstable trochanteric fracture femur

  11. The role of sensory signals from the insect coxa-trochanteral joint in controlling motor activity of the femur-tibia joint.

    Interjoint coordination in multi-jointed limbs is essential for the generation of functional locomotor patterns. Here we have focused on the role that sensory signals from the coxa-trochanteral (CT) joint play in patterning motoneuronal activity of the femur-tibia (FT) joint in the stick insect middle leg. This question is of interest because when the locomotor system is active, movement signals from the FT joint are known to contribute to patterning of activity of the central rhythm-generating networks governing the CT joint. We investigated the influence of femoral levation and depression on the activity of tibial motoneurons. When the locomotor system was active, levation of the femur often induced a decrease or inactivation of tibial extensor activity while flexor motoneurons were activated. Depression of the femur had no systematic influence on tibial motoneurons. Ablation experiments revealed that this interjoint influence was not mediated by signals from movement and/or position sensitive receptors at the CT joint, i.e., trochanteral hairplate, rhombal hairplate, or internal levator receptor organ. Instead the influence was initiated by sensory signals from a field of campaniform sensillae, situated on the proximal femur (fCS). Selective stimulation of these fCS produced barrages of inhibitory postsynaptic potentials (IPSPs) in tibial extensor motoneurons and activated tibial flexor motoneurons. During pharmacologically activated rhythmic activity of the otherwise isolated mesothoracic ganglion (pilocarpine, 5 x 10(-4) M), deafferented except for the CT joint, levation of the femur as well had an inhibitory influence on tibial extensor motoneurons. However, the influence of femoral levation on the rhythm generated was rather labile and only sometimes a reset of the rhythm was induced. In none of the preparations could entrainment of rhythmicity by femoral movement be achieved, suggesting that sensory signals from the CT joint only weakly affect central

    Neuropathic pain is caused by a lesion or disease of the somatosensory system, including peripheral fibres (Aβ, Aδ and C fibres) and central neurons, and affects 7–10% of the general population. Multiple causes of neuropathic pain have been described and its incidence is likely to increase owing to the ageing global population, increased incidence of diabetes mellitus and improved survival from cancer after chemotherapy. Indeed, imbalances between excitatory and inhibitory somatosensory signalling, alterations in ion channels and variability in the way that pain messages are modulated in the central nervous system all have been implicated in neuropathic pain. The burden of chronic neuropathic pain seems to be related to the complexity of neuropathic symptoms, poor outcomes and difficult treatment decisions. Importantly, quality of life is impaired in patients with neuropathic pain owing to increased drug prescriptions and visits to health care providers, as well as the morbidity from the pain itself and the inciting disease. Despite challenges, progress in the understanding of the pathophysiology of neuropathic pain is spurring the development of new diagnostic procedures and personalized interventions, which emphasize the need for a multidisciplinary approach to the management of neuropathic pain.

    Reverse oblique intertrochanteric fractures have unique mechanical characteristics and are often treated with intramedullary implants. We compared the outcomes of the reconstruction trochanteric antegrade nail (TAN) with the proximal femoral nail antirotation (PFNA). Between July 2008 and February 2014, we reviewed all patients with reverse oblique intertrochanteric fractures treated at our hospital. Patients with pathological fractures and those who were treated with other than TAN and PFNA nailing systems were excluded. Preoperative assessment included the Abbreviated mental test score (AMT), the ASA grade, pre-injury mobility and place of residence. Postoperative outcome measures included the type of implant used, time to fracture union, failures of fixation and revision surgeries. Fifty-eight patients were included and divided into two groups based on the treatment: 22 patients treated with TAN and 36 patients treated with PFNA systems. The two groups were well matched with regards to demographics and fracture type. The overall union rate was similar in both groups but the time to union was shorter in the TAN group. There were 8 implant failures in the PFNA (22.2%) group compare to none in the TAN group. Implant failure was associated with the severity of fracture (AO 31.A3.3) but was not related to fracture malreduction or screw position (Tip-apex-distance). Our study suggests that the use of reconstruction system with two screws such as TAN may be more suitable implant for reverse oblique intertrochanteric hip fractures.

    Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

  19. Physical activity behavior predicts endogenous pain modulation in older adults.

    PubMed

    Naugle, Kelly M; Ohlman, Thomas; Naugle, Keith E; Riley, Zachary A; Keith, NiCole R

    2017-03-01

    Older adults compared with younger adults are characterized by greater endogenous pain facilitation and a reduced capacity to endogenously inhibit pain, potentially placing them at a greater risk for chronic pain. Previous research suggests that higher levels of self-reported physical activity are associated with more effective pain inhibition and less pain facilitation on quantitative sensory tests in healthy adults. However, no studies have directly tested the relationship between physical activity behavior and pain modulatory function in older adults. This study examined whether objective measures of physical activity behavior cross-sectionally predicted pain inhibitory function on the conditioned pain modulation (CPM) test and pain facilitation on the temporal summation (TS) test in healthy older adults. Fifty-one older adults wore an accelerometer on the hip for 7 days and completed the CPM and TS tests. Measures of sedentary time, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) were obtained from the accelerometer. Hierarchical linear regressions were conducted to determine the relationship of TS and CPM with levels of physical activity, while controlling for demographic, psychological, and test variables. The results indicated that sedentary time and LPA significantly predicted pain inhibitory function on the CPM test, with less sedentary time and greater LPA per day associated with greater pain inhibitory capacity. Additionally, MVPA predicted pain facilitation on the TS test, with greater MVPA associated with less TS of pain. These results suggest that different types of physical activity behavior may differentially impact pain inhibitory and facilitatory processes in older adults.

    When explored separately, child and parent catastrophic thoughts about child pain show robust negative relations with child pain. The objective of this study was to conduct a dyadic analysis to elucidate intrapersonal and interpersonal influences of child and parent pain catastrophizing on aspects of pain communication, including observed behaviours and perceptions of child pain. A community sample of 171 dyads including children aged 8 to 12 years (89 girls) and parents (135 mothers) rated pain catastrophizing (trait and state versions) and child pain intensity and unpleasantness following a cold pressor task. Child pain tolerance was also assessed. Parent-child interactions during the cold pressor task were coded for parent attending, nonattending, and other talk, and child symptom complaints and other talk. Data were analyzed using the actor-partner interdependence model and hierarchical multiple regressions. Children reporting higher state pain catastrophizing had greater symptom complaints regardless of level of parent state pain catastrophizing. Children reporting low state pain catastrophizing had similar high levels of symptom complaints, but only when parents reported high state pain catastrophizing. Higher child and parent state and/or trait pain catastrophizing predicted their own ratings of higher child pain intensity and unpleasantness, with child state pain catastrophizing additionally predicting parent ratings. Higher pain tolerance was predicted by older child age and lower child state pain catastrophizing. These newly identified interpersonal effects highlight the relevance of the social context to children's pain expressions and parent perceptions of child pain. Both child and parent pain catastrophizing warrant consideration when managing child pain.

    2016-03-01

    Identifying clinical neuropathic pain phenotypes is a first step to better understand the underlying pain mechanisms after spinal cord injury (SCI). The primary purpose of the present study was to characterize multidimensional neuropathic pain phenotypes based on quantitative sensory testing (QST), pain intensity, and utilization of catastrophizing coping strategies. Thermal perception, thermal pain, and vibratory perception thresholds were assessed above and below the level of injury (LOI) in 101 persons with SCI and neuropathic pain, 18 persons with SCI and no neuropathic pain, and 50 able-bodied, pain-free controls. Cluster analysis of QST z-scores below the LOI, pain intensity ratings, and the Coping Strategies Questionnaire (CSQ) catastrophizing subscale scores in subjects with neuropathic pain resulted in two phenotypes: severe neuropathic pain (SNP) with greater pain intensity (7.39 ± 1.57) and thermal and vibratory sensitivity compared with the moderate neuropathic pain (MNP; 5.40 ± 1.43). A factor analysis including all CSQ subscales, the Neuropathic Pain Symptom Inventory (NPSI) total score, and thermal pain sensitivity above and below the LOI resulted in three factors: (1) adaptive pain coping including increasing activities, diverting attention, and reinterpreting pain sensations; (2) catastrophizing, neuropathic pain, and thermal sensitivity including greater NPSI total score, thermal pain sensitivity below the LOI, and catastrophizing; and (3) general pain sensitivity including greater thermal pain sensitivity above the LOI and lower catastrophizing. Our results suggest that neuropathic pain symptom severity post-SCI is significantly associated with residual spinothalamic tract function below the LOI and catastrophizing pain coping.

    Among the clinically relevant pain conditions, pain in the musculoskeletal system is most frequent. This article reports extensive epidemiological data on musculoskeletal system pain in Germany and worldwide. Since back pain is most frequent, the diagnostics and therapeutic algorithms of acute, recurring, and chronic lower back pain in Germany will be particularly addressed. The importance of the physiologic-organic, the cognitive-emotional, the behavioral, and the social level to diagnostics and treatment will be discussed. We will also focus on osteoarthritic pain and address its epidemiology, clinical importance, and significance for the health care system. This article will list some reasons why the musculoskeletal system in particular is frequently the site of chronic pain. The authors believe that these reasons are to be sought in the complex structures of the musculoskeletal system; in the particular sensitivity of the deep somatic nociceptive system for long-term sensitization processes, as well as the ensuing nervous system reactions; and in the interactions between the nervous and immune systems. The article will give some insights into the research carried out on this topic in Germany.

    During the last few years a vivid debate, both scientifically and emotionally, has risen in the medical literature as to whether a fetus is able to feel pain during abortion or intrauterine surgery. This debate has mainly been inspired by the demonstration of various hormonal or motor reactions to noxious stimuli at very early stages of fetal development. The aims of this paper are to review the literature on development of the pain system in the fetus, and to speculate about the relationship between "sensing" as opposed to "feeling" pain and the number of reactions associated with painful stimuli. While a cortical processing of pain theoretically becomes possible after development of the thalamo-cortical connections in the 26th week of gestation, noxious stimuli may trigger complex reflex reactions much earlier. However, more important than possible painfulness is the fact that the noxious stimuli, by triggering stress responses, most likely affect the development of an individual at very early stages. Hence, it is not reasonable to speculate on the possible emotional experiences of pain in fetuses or premature babies. A clinically relevant aim is rather to avoid and/or treat any possibly noxious stimuli, and thereby prevent their potential adverse effects on the subsequent development.

    It has been suggested that increased pain sensitivity and disruption of endogenous pain inhibitory processes may account, at least in part, for the greater prevalence and severity of chronic pain in women compared to men. However, previous studies addressing this topic have produced mixed findings. This study examined sex differences in pain sensitivity and inhibition using quantitative sensory testing (QST), while also considering the influence of other important factors such as depressive symptoms and sleep quality. Healthy men (n=24) and women (n=24) each completed a QST battery. This battery included an ischemic pain task (IPT) that used a submaximal effort tourniquet procedure as well as a conditioned pain modulation (CPM) procedure for the assessment of endogenous pain inhibition. Prior to QST, participants completed the Center for Epidemiologic Studies Depression Scale and the Pittsburgh Sleep Quality Index. Analyses revealed significant sex differences for the ischemic pain task and the conditioned pain modulation procedure, such that women tolerated the ischemic pain for a shorter amount of time and demonstrated less pain inhibition compared with men. This remained true even when accounting for sex differences in depressive symptoms and sleep quality. The results of this study suggest that women may be more pain sensitive and possess less-efficient endogenous pain inhibitory capacity compared with men. Whether interventions that decrease pain sensitivity and enhance pain inhibition in women ultimately improve their clinical pain outcomes is an area of research that deserves additional attention in the future.

  8. Thoracolumbar pain among fighter pilots.

    1999-08-01

    High +Gz forces place high stress on the spinal column, and fighter pilots flying high-performance fighter aircraft frequently] report work-related thoracic and lumbar spine pain. The aim of this study was to determine whether +Gz exposure causes work-related thoracolumbar spine pain among fighter pilots. A questionnaire was used to establish the occurrence of thoracic and lumbar spine pain during the preceding 12 months and during duties over the whole working career among 320 fighter pilots and 283 nonflying controls matched for age and sex. Thirty-two percent of the pilots and 19% of the controls had experienced pain in the thoracic spine during the preceding 12 months (odds ratio [OR] = 2.3; 95% confidence interval [CI] = 1.5-3.5; p = 0.002 for the pilots). Among the pilots, the OR increased up to 6.1 (95% CI = 1.6-23.1; p = 0.0007) with the number of +Gz flight hours. There was no difference between the groups with regard to lumbar pain during the preceding 12 months, but over their whole working careers fighter pilots (58%) had experienced lumbar pain during their duties more often than controls (48%) (OR = 1.8; 95% CI = 1.3-2.6; p = 0.002). The greater the number of +Gz flight hours, the greater the occurrence of lumbar spine pain when on duty (OR = 26.9; 95% CI = 6.2-116; p = 0.0001 for the most experienced fighter pilots). The same was not true with regard to the number of +Gz flight hours and lumbar pain during the preceding 12 months. Age had no effect on pain in the thoracic or lumbar spine. Fighter pilots flying high-performance aircraft have more work-related thoracic and lumbar spine pain than controls of the same age and sex. The difference is explained by the pilots' exposure to +Gz forces.

    developed by the American psychiatrist George Engel, defined chronic pain as an illness rather than a disease. Concurrently, the radical behaviorism of the late 1960s affected both the therapy of chronic and of acute pain. Based on this theory, patient-controlled analgesia (PCA) was introduced in the 1970s and 1980s. Acute pain services (APS) in hospitals, were developed beginning in the 1980s using the continuous release of opioids. Regional anesthesia played a greater role than general anesthesia in developing pain therapy in the twentieth century and paved the way for pain therapy. The restriction to nerve blocks in pain centers was overcome by the expansion of theoretical foundations beyond the framework of anesthesiology. Impulses from psychology and psychosomatic medicine were crucial. The evolution of cancer pain therapy was distinct from non-cancer pain therapy.

    Abdominal pain can result from a variety of different intra- and extra-abdominal disorders. Given the wide variety of etiological triggers for this pain, the primary task during the first stage of the diagnostic work-up is to determine as soon as possible the underlying cause and the degree of emergency. The aim of this evaluation is to adapt the therapeutic measures which are necessary for a causal treatment to the individual situation. Contrary to somatic causes of abdominal pain, the availability of such a causal therapy for functional bowel disorders is still very limited. Given this dilemma, the therapeutic focus of abdominal pain associated with these functional syndromes has to be placed on symptom-oriented treatment.

  19. Fetal pain.

    PubMed

    Rokyta, Richard

    2008-12-01

    The fetus reacts to nociceptive stimulations through different motor, autonomic, vegetative, hormonal, and metabolic changes relatively early in the gestation period. With respect to the fact that the modulatory system does not yet exist, the first reactions are purely reflexive and without connection to the type of stimulus. While the fetal nervous system is able to react through protective reflexes to potentially harmful stimuli, there is no accurate evidence concerning pain sensations in this early period. Cortical processes occur only after thalamocortical connections and pathways have been completed at the 26th gestational week. Harmful (painful) stimuli, especially in fetuses have an adverse effect on the development of humans regardless of the processes in brain. Moreover, pain activates a number of subcortical mechanisms and a wide spectrum of stress responses influence the maturation of thalamocortical pathways and other cortical activation which are very important in pain processing.

  1. Differential pain modulation properties in central neuropathic pain after spinal cord injury.

    PubMed

    Gruener, Hila; Zeilig, Gabi; Laufer, Yocheved; Blumen, Nava; Defrin, Ruth

    2016-07-01

    It seems that central neuropathic pain (CNP) is associated with altered abilities to modulate pain; whereas dysfunction in descending pain inhibition is associated with the extent of chronic pain distribution, enhanced pain excitation is associated with the intensity of chronic pain. We investigated the hypothesis that CNP is associated with decreased descending pain inhibition along with increased neuronal excitability and that both traits are associated with spinothalamic tract (STT) damage. Chronic spinal cord injury subjects with CNP (n = 27) and without CNP (n = 23) and healthy controls (n = 20) underwent the measurement of pain adaptation, conditioned pain modulation (CPM), tonic suprathreshold pain (TSP), and spatial summation of pain above injury level. Central neuropathic pain subjects also underwent at and below-lesion STT evaluation and completed the questionnaires. Central neuropathic pain subjects showed decreased CPM and increased enhancement of TSP compared with controls. Among CNP subjects, the dysfunction of CPM and pain adaptation correlated positively with the number of painful body regions. The magnitude of TSP and spatial summation of pain correlated positively with CNP intensity. STT scores correlated with CNP intensity and with TSP, so that the more affected the STT below injury level, the greater the CNP and TSP magnitude. It seems that CNP is associated with altered abilities to modulate pain, whereas dysfunction in descending pain inhibition is associated with the extent of chronic pain distribution and enhanced pain excitation is associated with the intensity of chronic pain. Thus, top-down processes may determine the spread of CNP, whereas bottom-up processes may determine CNP intensity. It also seems that the mechanisms of CNP may involve STT-induced hyperexcitability. Future, longitudinal studies may investigate the timeline of this scenario.

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Purpose We conducted a study on patients who underwent hip joint arthroplasty because of unstable femur intertrochanteric fractures with greater trochanter bony fragments. After dividing patients into three groups depending on their fracture patterns, we evaluated the clinical and radiological outcomes of different operation methods applied to each of these groups. Materials and Methods Using Evan's classification, we defined an unstable intertrochanteric fracture as those characterized as stage 4 or 5. Of the 137 patients presenting with an intertrochanteric fracture with osteoporosis (bone mineral density, <−2.5) between March 2014 and October 2015, 63 met the eligibility criteria and were included in this study. Next, patients were divided into three groups based on their greater trochanter fracture patterns (discerned with three-dimensional computed tomography images); different fixation methods were applied to each group by a single orthopaedic surgeon. Results Taken as a whole, 50 out of 63 patients experienced no reduction in walking distance in their daily lives. Harris hip score increased from 74.8 to 85.7 point and we considered this a relatively good result. Radiologically, we observed complete bone union in 62 cases (98.4%); the lone exception was in a patient who experienced osteolysis. There were also 3 cases who removed greater trochanter reattachment device due to broken implant and 1 case of dislocation. Conclusion The different fixation methods applied to three distinct groups with varying fractures patterns were successful in achieving proper reduction and fixation of greater trochanteric fractures. We also observed reduced bone union periods when arthroplasty was performed in patients with unstable intertrochanteric fractures. Lastly, we believe these approaches may also aid in achieving early ambulation and early rehabilitations. PMID:28316964

  5. Children's selective attention to pain and avoidance behaviour: the role of child and parental catastrophizing about pain.

    2013-10-01

    The present study investigated selective attention to pain in children, its implications for child avoidance behaviour, and the moderating role of dimensions comprising child and parental catastrophizing about pain (ie, rumination, magnification, and helplessness). Participants were 59 children (31 boys) aged 10-16 years and one of their parents (41 mothers). Children performed a dot-probe task in which child facial pain displays of varying pain expressiveness were presented. Child avoidance behaviour was indexed by child pain tolerance during a cold-pressor task. Children and parents completed measures of child and parent pain catastrophizing, respectively. Findings indicated that both the nature of child selective attention to pain and the impact of selective attention upon child avoidance behaviour were differentially sensitive to specific dimensions of child and parental catastrophizing. Specifically, findings showed greater tendency to shift attention away from pain faces (i.e.,, attentional avoidance) among children reporting greater pain magnification. A similar pattern was observed in terms of parental characteristics, such that children increasingly shifted attention away from pain with increasing levels of parental rumination and helplessness. Furthermore, child attentional avoidance was associated with greater avoidance behaviour (i.e., lower pain tolerance) among children reporting high levels of pain magnification and those whose parents reported greater rumination about pain. The current findings corroborate catastrophizing as a multidimensional construct that may differentially impact outcomes and attest to the importance of assessing both child and parental characteristics in relation to child pain-related attention and avoidance behaviour. Further research directions are discussed.

    The authors compared the pain intensity and difficulty experienced in performing activities of daily living (ADL) among 237 patients with orofacial pain. The patients underwent comprehensive examinations and recorded their subjective symptoms on a form (five items for pain intensity and six for ADL-related difficulty). On the basis of the primary diagnosis, the patients were divided into the temporomandibular joint dysfunction (TMJ), myofascial pain (MP), neuropathic pain (NP), and fibromyalgia (FM) groups. The intensity of pain in the jaw/face, tightness in the jaw/face, pain in the neck, and toothache significantly differed among the groups (p < 0.01, Kruskal-Wallis test). Compared to other patients, the FM and NP groups reported greater pain intensity, whereas those in the TMJ group reported lesser pain intensity. The ADL-related difficulty was not significantly different among the groups. Thus, compared to pain due to joint-related disorders, myalgic and neuropathic pain seem to be of higher intensity.

    Pain is one of the primary symptoms of juvenile idiopathic arthritis (JIA). JIA patients have reduced pain tolerance and pain threshold compared to healthy controls. In children with JIA the greater use of coping strategies such as problem-solving, positive self-statements and distraction consistently have predicted less arthritis-related pain, even after controlling for relevant medical and demographic variables. Interventions specifically designed to modify maladaptive pain coping strategies and pain-related health beliefs may be effective in reducing pain in children with JIA.

    Objectives In the context of widespread opioid use, increased emphasis has been placed on the potentially deleterious effects of concurrent benzodiazepine (BZD) and opioid use. Although use of opioids in chronic pain has been a major focus, BZD use is equally concerning. Thus, the primary aim of this study was to determine the associations between BZD and opioid use in adults with chronic pain upon admission to an outpatient interdisciplinary pain rehabilitation (IPR) program. Methods The study cohort involved 847 consecutive patients admitted to a 3-week outpatient IPR program from January 2013 through December 2014. Study variables included baseline demographic and clinical characteristics, Center for Epidemiologic Studies-Depression Scale, Pain Catastrophizing Scale, and the pain severity subscale of the Multidimensional Pain Inventory. Results Upon admission, 248 (29%) patients were taking BZDs. Patients using BZDs were significantly more likely to use opioids and to be female. Additionally, patients using BZDs had significantly greater depression, pain catastrophizing, and pain severity scores. In univariable logistic regression analysis, opioid use, female sex, and greater scores of depression, pain catastrophizing, and pain severity were significantly associated with BZD use. In multivariable logistic regression analysis adjusted for age, sex, pain duration, opioid use, depression, pain catastrophizing, and pain severity, only female sex and greater depression scores were significantly associated with BZD use. Discussion Among patients participating in an outpatient IPR program, female sex and greater depression scores were associated with BZD use. Results identify a high prevalence of BZD use in patients with chronic pain and reinforce the need to weigh the risks versus benefits when prescribing in this patient population. PMID:28223841

    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.

    There is much evidence to suggest that psychological and social issues are predictive of pain severity, emotional distress, work disability, and response to medical treatments among persons with chronic pain. Psychologists can play an important role in the identification of psychological and social dysfunction and in matching personal characteristics to effective interventions as part of a multidisciplinary approach to pain management, leading to a greater likelihood of treatment success. The assessment of different domains using semi-structured clinical interviews and standardized self-report measures permits identification of somatosensory, emotional, cognitive, behavioral and social issues in order to facilitate treatment planning. We briefly describe measures to assess constructs related to pain and intervention strategies for the behavioral treatment of chronic pain and discuss related psychiatric and substance abuse issues. Finally, we offer a future look at the role of integrating pain management in clinical practice in the psychological assessment and treatment for persons with chronic pain. PMID:22383018

    The clinical manifestations of Marfan syndrome frequently cause pain. This study aimed to characterize pain in a cohort of adults with Marfan syndrome and investigate demographic, physical, and psychological factors associated with pain and pain-related disability. Two hundred and forty-five participants (73% female, 89% non-Hispanic white, 90% North American) completed an online questionnaire assessing clinical features of Marfan syndrome, pain severity, pain-related disability, physical and mental health, depressive symptoms, pain catastrophizing, and insomnia. Eighty-nine percent of respondents reported having pain with 28% of individuals reporting pain as a presenting symptom of Marfan syndrome. Almost half of individuals reported that pain has spread from its initial site. Participants in our study reported poor physical and mental health functioning, moderate pain-related disability, and mild levels of depressive symptoms, sleep disturbances, and pain catastrophizing. Those who identified pain as an initial symptom of Marfan syndrome and those who reported that pain had spread from its initial site reported greater psychological burden compared with those without pain as an initial symptom or pain spreading. Physical health is the largest predictor of pain severity and pain-related disability. While pain catastrophizing and worse mental health functioning are significant correlates of pain severity and pain-related disability, respectively. Pain is a significant and persistent problem in Marfan syndrome and is associated with profound disability and psychological burden. Further studies are indicated to better characterize the directionality of pain, pain-related disability, and psychological burden in Marfan syndrome. © 2016 Wiley Periodicals, Inc.

    Illness-specific cognitions are associated with outcomes in numerous health conditions, however, little is known about their role in noncardiac chest pain (NCCP). NCCP is prevalent, impairing, and associated with elevated health care utilization. Our objective was to investigate the relations between illness perceptions, emotion, and pain in a sample of 196 adult patients diagnosed with NCCP. We found that negative illness perceptions were associated with greater anxiety, depression, chest pain, and pain-related life interference while controlling for the effects of demographic and pain-related variables. These results expand current NCCP theory and may inform future treatment development.

    Ketoprofen is a nonsteroidal antiinflammatory drug, recently approved as an over-the-counter (OTC) analgesic at a 12.5 mg dosage strength. This is the first published study which explores the analgesic efficacy and safety of ketoprofen 12.5 mg in patients experiencing pain following the removal of impacted third molars. This study was single-dose, double-blind and randomized utilizing a 6-hour in-patient evaluation period. Patients ingested a single dose of ketoprofen 12.5 mg (n = 30), ketoprofen 37.5 mg (n = 32) or placebo (n = 15) when their post-surgical pain reached at least a moderate intensity on a 5-point categorical (CAT) scale and greater than 50 mm on a 100 mm visual analog scale (VAS). Measures of pain intensity and relief were gathered every 20 minutes for the first 2 hours, and then hourly from hours 3 through 6. Adverse drug reactions were also recorded as they occurred. Both dosages of ketoprofen were significantly more efficacious than placebo (two way ANOVAs, p < 0.05). For pain intensity difference (PID) and pain relief, the 12.5 mg dose exhibited statistical superiority from hours 1 through 3, while the 37.5 mg dose exhibited statistical superiority from 40 minutes through 4 hours. Ketoprofen 37.5 mg was significantly more efficacious than the 12.5 mg dose only at 40 minutes for PID(VAS) and relief, and at 60 minutes for PID(VAS). Both ketoprofen dosages displayed significantly greater 3-hr, 4-hr and 6-hr summary analgesic measures (SPID(VAS), SPID(CAT), TOTPAR) than placebo, with the exception of the 6-hr SPID(CAT) measure for ketoprofen 12.5 mg. No serious side effects were observed in this study. We conclude that ketoprofen in a dose range of 12.5 mg to 37.5 mg is a safe and effective analgesic for the relief of post-operative dental pain.

    Background Prior investigations into facial pain associated with chronic rhinosinusitis (CRS) have yielded important results, but have yet to utilize pain-specific outcome measures. This study seeks to characterize facial pain associated with CRS using validated pain-specific instruments. Methods Adults with CRS were enrolled into a prospective, cross-sectional study along with control participants presenting with non-CRS diagnoses. Facial pain was characterized in both groups using the Brief Pain Inventory Short Form (BPI-SF) and the Short-Form McGill Pain Questionnaire (SF-MPQ). CRS-specific measures of disease were measured including the Sinonasal Outcome Test-22 (SNOT-22), nasal endoscopy, and computed tomography scoring. Results Patients were comprised of CRS with nasal polyposis (CRSwNP; n=25), CRS without nasal polyposis (CRSsNP; n=30), and control participants (n=8). Subjects with CRSwNP and CRSsNP were less likely to be pain free than controls (16.0%, 6.7% and 62.5% respectively, p=0.001) and carried greater burden of pain as measured by the BPI-SF and SF-MPQ than controls (p=0.002 and p=0.017, respectively). Pain in CRS was most commonly located around the eyes and characterized as ‘throbbing’ and ‘aching’. Nasal polyp status was not associated with differences in character, severity, or location of pain. Conclusions Subjects with CRS have a greater burden of facial pain relative to control subjects across several standardized pain measures. Further, facial pain in CRS significantly correlated to QOL and CRS-specific disease severity measures. Study across larger cohorts using standardized pain measures is warranted to clarify the association of facial pain with chronic rhinosinusitis. PMID:26074476

    Pain and alcohol use are both highly prevalent in the general population, and pain-alcohol interrelations are of increasing empirical interest. Previous research has identified associations between pain and alcohol dependence, and the current review provides novel contributions to this emerging domain by incorporating studies that have tested relations between pain and low-to-moderate alcohol consumption, and by identifying potential psychosocial mechanisms of action. Specifically, we sought to integrate evidence of pain-alcohol relations derived from two directions of empirical inquiry (i.e., effects of alcohol on pain and effects of pain on alcohol use) across psychological, social, and biological literatures. We observed converging evidence that associations between alcohol consumption and pain may be curvilinear in nature. Whereas moderate alcohol use was observed to be associated with positive pain-related outcomes (e.g., greater quality of life), excessive drinking and alcohol use disorder appear to be associated with deleterious pain-related outcomes (e.g., greater pain severity). We also observed evidence that alcohol administration confers acute pain-inhibitory effects, and that situational pain may motivate alcohol consumption (e.g., drinking for pain-coping). Future research can inform theoretical and clinical applications through examination of temporal relations between pain and alcohol consumption, tests of hypothesized mechanisms, and the development of novel interventions.

    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.

    The objective of this preliminary study was to examine the extent to which affective marital interaction related to depressive symptoms in persons with chronic pain and their spouses and to pain severity in persons with pain. Couples from the community completed self-report surveys and engaged in a videotaped conversation on a topic of mutual disagreement that was coded for three affect types (i.e., anger/contempt, sadness, humor). Humor was positively related to marital satisfaction in both partners. Spouse anger/contempt and sadness were positively related to depressive symptoms in spouses. Several significant interaction effects between couple pain status (i.e., whether one or both partners reported pain) and affect also emerged. Specifically, sadness in the participant designated as the person with pain was associated with greater depressive symptoms and pain severity when only he or she reported pain whereas sadness was related to fewer depressive symptoms and less pain severity when both partners reported pain. The relationships between spouse anger and spouse depressive symptoms and between spouse humor and pain severity in the person with pain were also moderated by couple pain status. These exploratory findings can be interpreted in light of emotion regulation and pain empathy theories. For example, partners who have not experienced pain themselves may fail to empathize with persons in pain, thus preventing effective emotion regulation. When both spouses report chronic pain, expressions of negative affect may instead promote emotion regulation because the affect is experienced with a spouse who may be more empathetic.

    Objective One potential consequence of chronic opioid analgesic administration is a paradoxical increase of pain sensitivity over time. Little scientific attention has been given to how cessation of opioid medication affects the hyperalgesic state. In this study, we examined the effects of opioid tapering on pain sensitivity in chronic pain patients. Design Twelve chronic pain patients on long-term opioid analgesic treatment were observed in a 7- to 14-day inpatient pain rehabilitation program, with cold pain tolerance assessed at admission and discharge. The majority of participants were completely withdrawn from their opioids during their stay. Outcome Measures We hypothesized that those patients with the greatest reduction in daily opioid use would show the greatest increases in pain tolerance, as assessed by a cold pressor task. Results A linear regression revealed that the amount of opioid medication withdrawn was a significant predictor of pain tolerance changes, but not in the direction hypothesized. Greater opioid reduction was associated with decreased pain tolerance. This reduction of pain tolerance was not associated with opioid withdrawal symptoms or changes in general pain. Conclusions These findings suggest that the withdrawal of opioids in a chronic pain sample leads to an acute increase in pain sensitivity. PMID:18564998

  7. Empathy gaps for social pain: why people underestimate the pain of social suffering.

    In 5 studies, the authors examined the hypothesis that people have systematically distorted beliefs about the pain of social suffering. By integrating research on empathy gaps for physical pain (Loewenstein, 1996) with social pain theory (MacDonald & Leary, 2005), the authors generated the hypothesis that people generally underestimate the severity of social pain (ostracism, shame, etc.)--a biased judgment that is only corrected when people actively experience social pain for themselves. Using a social exclusion manipulation, Studies 1-4 found that nonexcluded participants consistently underestimated the severity of social pain compared with excluded participants, who had a heightened appreciation for social pain. This empathy gap for social pain occurred when participants evaluated both the pain of others (interpersonal empathy gap) as well as the pain participants themselves experienced in the past (intrapersonal empathy gap). The authors argue that beliefs about social pain are important because they govern how people react to socially distressing events. In Study 5, middle school teachers were asked to evaluate policies regarding emotional bullying at school. This revealed that actively experiencing social pain heightened the estimated pain of emotional bullying, which in turn led teachers to recommend both more comprehensive treatment for bullied students and greater punishment for students who bully.

  8. Provocative sacroiliac joint maneuvers and sacroiliac joint block are unreliable for diagnosing sacroiliac joint pain.

    Mapping studies of pain elicited by injections into the sacroiliac joints (SIJs) suggest that sacroiliac joint syndrome (SIJS) may manifest as low back pain, sciatica, or trochanteric pain. Neither patient-reported symptoms nor provocative SIJ maneuvers are sensitive or specific for SIJS when SIJ block is used as the diagnostic gold standard. This has led to increasing diagnostic use of SIJ block, a procedure in which an anesthetic is injected into the joint under arthrographic guidance. However, several arguments cast doubt on the validity of SIJ block as a diagnostic gold standard. Thus, the effects of two consecutive blocks are identical in only 60% of cases, and the anesthetic diffuses out of the joint in 61% of cases, often coming into contact with the sheaths of the adjacent nerve trunks or roots, including the lumbosacral trunk (which may contribute to pain in the groin or thigh) and the L5 and S1 nerve roots. These data partly explain the limited specificity of SIJ block for the diagnosis of SIJS and the discordance between the pain elicited by the arthrography injection and the response to the block. The limitations of provocative maneuvers and SIJ blocks may stem in part from a contribution of extraarticular ligaments to the genesis of pain believed to originate within the SIJs. These ligaments include the expansion of the iliolumbar ligaments, the dorsal and ventral sacroiliac ligaments, the sacrospinous ligaments, and the sacrotuberous ligaments (sacroiliac joint lato-sensu). They play a role in locking or in allowing motion of the SIJs. Glucocorticoids may diffuse better than anesthetics within these ligaments. Furthermore, joint fusion may result in ligament unloading.

    Background: The prevalence of chronic pain is high and increasing. Medication management is an important component of chronic pain management. There is a shortage of physicians who are available and comfortable providing this service. In Alberta, pharmacists have been granted an advanced scope of practice. Given this empowerment, their availability, training and skill set, pharmacists are well positioned to play an expanded role in the medication management of chronic pain sufferers. Objective: To compare the effectiveness and cost of a physician-only vs a pharmacist-physician team model of medication management for chronic nonmalignant pain sufferers. Method: Data was analyzed for 89 patients who had received exclusively medication management at a rural Alberta multidisciplinary clinic. 56 were managed by a sole physician. 33 were managed by a team (pharmacist + physician). In the team model, the physician did the medical assessment, diagnosis, and established a treatment plan in consultation with the patient and pharmacist. The pharmacist then provided the ongoing follow-up including education, dose titration and side effect management and consulted with the physician as needed. Change in pain (Numerical Rating Scale) and disability (Pain Interference Questionnaire) over the course of treatment were recorded. The treatment duration and number of visits were used to calculate cost of care. Results: Both models of medication management resulted in significant and comparable improvements in pain, disability and patient perception of medication effectiveness. Patients in the physician-only group were seen more frequently and at a greater cost. The pharmacist-physician team approach was markedly more cost-effective, and patients expressed a high level of satisfaction with their medication management. Conclusions: The pharmacist-physician team model of medication management results in significant reductions of pain and disability for chronic nonmalignant pain sufferers

  10. Neck pain

    2008-01-01

    Introduction Non-specific neck pain has a postural or mechanical basis and affects about two thirds of people at some stage, especially in middle age. Acute neck pain resolves within days or weeks, but may become chronic in about 10% of people. Whiplash injuries follow sudden acceleration–deceleration of the neck, such as in road traffic or sporting accidents. Up to 40% of people continue to report symptoms 15 years after the accident, although this varies between countries. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for people with non-specific neck pain without severe neurological deficit? What are the effects of treatments for acute whiplash injury? What are the effects of treatments for chronic whiplash injury? What are the effects of treatments for neck pain with radiculopathy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 91 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of the evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, biofeedback, drug treatments (analgesics, antidepressants, epidural steroid injections, muscle relaxants, non-steroidal anti-inflammatory drugs [NSAIDs]), early mobilisation, early return to normal activity, exercise, heat or cold, manipulation (alone or plus exercise), mobilisation, multimodal treatment, patient education, percutaneous radiofrequency neurotomy

    Cues that 46 pediatric nurses with a BS in Nursing reported as key to their pain assessments of 88 videotaped infants, ages 0 to 12 months, are identified. Frequencies with which these cues were used for infants of different ages and the relationships between key cues and assessed levels of pain are described. Greater pain was strongly associated with tears, stiff posture, guarding, and fisting. Greater pain was moderately associated with inadequate type or dosage of analgesia, more recent surgery, inconsolability, difficult to distract, does not focus on surroundings, frown, grimace, wrinkled face, flushed face, pain cry, and increased arousal in response to touch of sore area. Internurse variability in cue use was sizable. Most of the often-used cues had weak or no association with assessed pain level. Only consolability, pain cry, grimace, and stiff posture were frequently used and correlated > .51 with assessed level of pain.

    While previous cross-sectional studies have found that negative beliefs about low back pain are associated with pain intensity, the relationship between back beliefs and persistent low back pain is not well understood. This cohort study aimed to examine the role of back beliefs in persistent low back pain in community-based individuals. A hundred and ninety-two participants from a previous musculoskeletal health study were invited to take part in a two-year follow-up study. Beliefs about back pain were assessed by the Back Beliefs Questionnaire (BBQ) at baseline and low back pain intensity was measured by the Chronic Pain Grade Questionnaire at baseline and follow-up. Of the 150 respondents (78.1%), 16 (10.7%) reported persistent high intensity low back pain, 12 (8.0%) developed high intensity low back pain, in 16 (10.7%) their high intensity low back pain resolved and 106 (70.7%) experienced no high intensity low back pain. While participants were generally positive about low back pain (BBQ mean (SD) = 30.2 (6.4)), those with persistent high intensity pain reported greater negativity (BBQ mean (SD) = 22.6 (4.9)). Negative beliefs about back pain were associated with persistent high intensity low back pain after adjusting for confounders (M (SE) = 23.5 (1.6) vs. >30.1 (1.7), p < .001). This study found negative back beliefs were associated with persistent high intensity low back pain over 2 years in community-based individuals. While further longitudinal studies are required, these findings suggest that targeting beliefs in programs designed to treat and prevent persistent high intensity low back pain may be important.

    Pain is a burdensome symptom that can commonly exist chronically along the cancer trajectory. Uncontrolled pain will impact on cancer patients' quality of life, even further negatively affect cancer survivors' employment. Based on systemic reviews of studies for past 10 years, the paper reported that although there is enormous advancement on the knowledge of cancer pain and pain management, studies still documented undertreatment of cancer pain globally. Additionally, pain distress a significant portion of cancer survivors. The pain in cancer survivors distinct from the pain related with cancer, instead emphasize on pain related with cancer treatment, such as neuropathic pain, muscular syndrome. Evidence-based pain management with common pain problems in cancer survivors is lacking. Further studies are needed to understand the pain in cancer survivors and to develop effective strategies in helping cancer survivors to manage their pain.

    Abstract Leptin, an appetite-regulatory hormone, is also known to act as a proinflammatory adipokine. One of the effects of increased systemic leptin concentrations may be greater sensitivity to pain. We report the results of two studies examining the association between leptin and pain: a small pilot longitudinal study, followed by a large cross-sectional study. In Study 1, three women with physician-diagnosed fibromyalgia provided blood draws daily for 25 consecutive days, as well as daily self-reported musculoskeletal pain. Daily fluctuations in serum leptin were positively associated with pain across all three participants (F (1,63) = 12.8, p < 0.001), with leptin predicting ∼49% of the pain variance. In Study 2, the relationship between leptin and body pain was examined in a retrospective cross-sectional analysis of 5676 generally healthy postmenopausal women from the Women's Health Initiative. Leptin levels obtained from single blood draws were tested for a relationship with self-reported body pain. Body mass index (BMI) was also included as a predictor of pain. Both leptin and BMI were found to be independently associated with self-reported pain (p = 0.001 and p < 0.001, respectively), with higher leptin levels and greater BMI each being associated with greater pain. Leptin appears to be a predictor of body pain both within- and between-individuals and may be a driver of generalized pain states such as fibromyalgia. PMID:27028709

    There is limited research describing the patterns of healthcare utilization in adolescents with chronic pain. This study describes healthcare utilization in a clinical chronic pain sample, and compares the patterns of service use of this group to a community sample with intermittent pain complaints. We also investigated demographic and clinical factors that predicted healthcare visits and medication use in the clinical sample. Data on 117 adolescents (aged 12-18; n=59 clinical pain sample, n=58 community) were collected. Caregivers and adolescents reported on sociodemographics, medical visits, current medications, pain, activity limitations, and depression. As hypothesized, the clinical pain sample had higher rates of healthcare consultation on all types of medical visits (general, specialty care, complementary medicine, mental health, OT/PT), and higher medication use compared to the community sample. Regression analyses revealed that higher annual income, greater pain frequency, and higher levels of caregiver reported activity limitations were associated with a greater number of healthcare visits for the total sample. Within the clinical pain sample, higher pain frequency and greater activity limitations (caregiver-report) predicted more specialty care visits. Additionally, higher income and greater levels of depressive symptoms predicted a higher number of prescribed medications. Perspective This study contributes to the limited available data on health service and medication use in a clinical chronic pain sample versus a community sample of adolescents. We also identify clinical factors (pain frequency, parent-reported activity limitations, depressive symptoms) and demographic factors (gender, income) associated with healthcare utilization.

  18. Central Neuropathic Pain Syndromes.

    PubMed

    Watson, James C; Sandroni, Paola

    2016-03-01

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

    Joint pain is common in haemophilia and may be acute or chronic. Effective pain management in haemophilia is essential to reduce the burden that pain imposes on patients. However, the choice of appropriate pain-relieving measures is challenging, as there is a complex interplay of factors affecting pain perception. This can manifest as differences in patients’ experiences and response to pain, which require an individualized approach to pain management. Prophylaxis with factor replacement reduces the likelihood of bleeds and bleed-related pain, whereas on-demand therapy ensures rapid bleed resolution and pain relief. Although use of replacement or bypassing therapy is often the first intervention for pain, additional pain relief strategies may be required. There is an array of analgesic options, but consideration should be paid to the adverse effects of each class. Nevertheless, a combination of medications that act at different points in the pain pathway may be beneficial. Nonpharmacological measures may also help patients and include active coping strategies; rest, ice, compression, and elevation; complementary therapies; and physiotherapy. Joint aspiration may also reduce acute joint pain, and joint steroid injections may alleviate chronic pain. In the longer term, increasing use of prophylaxis or performing surgery may be necessary to reduce the burden of pain caused by the degenerative effects of repeated bleeds. Whichever treatment option is chosen, it is important to monitor pain and adjust patient management accordingly. Beyond specific pain management approaches, ongoing collaboration between multidisciplinary teams, which should include physiotherapists and pain specialists, may improve outcomes for patients.

    Race and ethnicity shape the experience of pain in adults, with African Americans typically exhibiting greater pain intensity and evoked pain responsiveness than Non-Hispanic Whites. However, it remains unclear whether there are racial differences in conditioned pain modulation (CPM) and if these are present in youth. CPM refers to a reduction in perceived pain intensity for a test stimulus during application of a conditioning stimulus and may be especially relevant in determining risk for chronic pain. The present study assessed CPM to evoked thermal pain in 78 healthy youth (ages 10 to 17), 51% of whom were African American and 49% were Non-Hispanic White. African-American youth reported lower mean conditioning pain ratings than Non-Hispanic White youth, controlling for mean pre-conditioning pain ratings, which is consistent with stronger CPM. Multilevel models demonstrated stronger CPM effects in African-American than Non-Hispanic White youth, as evident in more rapid within-person decreases in pain ratings during the conditioning phase. These findings suggest that diminished CPM likely does not account for the enhanced responsiveness to evoked thermal pain observed in African-American youth. These results may have implications for understanding racial differences in chronic pain experience in adulthood. Perspective This study evaluated conditioned pain modulation to evoked thermal pain in African-American and Non-Hispanic White youth. Findings could have implications for the development of personalized chronic pain treatment strategies that are informed by race and ethnicity. PMID:26086899

    2015-01-01

    Study Objectives: Sleepwalking is a disorder characterized by arousal specifically from slow wave sleep with dissociated brain activity that may be related to lower nociceptive state. Our objectives were to assess the frequency of chronic pain, headache, and migraine in sleepwalkers compared to controls, examine the impact and determinants of pain in sleepwalkers, and report analgesia frequency during injurious parasomnia episodes. Design: Cross-sectional case-control study. Setting: Data were collected at the Sleep Disorders Center, Montpellier, France. Participants: One hundred patients with sleepwalking were assessed for disease characteristics, sleep (polysomnography, sleepiness, and insomnia), pain (chronic pain, multidimensional pain inventory, headache, and migraine), depressive symptoms, and quality of life compared to 100 adult controls. Pain perception was retrospectively assessed during injurious parasomnia episodes. Measurements and Results: Raw association data showed that lifetime headache, migraine, and chronic pain at time of study were significantly associated with sleepwalking (also called somnambulism). Compared to controls, sleepwalkers reported more frequent daytime sleepiness, and depressive and insomnia symptoms. After adjustments, sleepwalking was associated with increased risk for headache and migraine only. Compared to pain-free sleepwalkers, sleepwalkers with chronic pain were more likely to be older and to have greater daytime sleepiness, insomnia, and depressive symptoms, with no difference in polysomnography assessment. Of the 47 sleepwalkers with at least one previous violent parasomnia episode, 78.7% perceived no pain during episodes, allowing them to remain asleep despite injury. Conclusion: Our results highlight the clinical enigma of pain in sleepwalking patients with complaints of frequent chronic pain, migraine, and headache during wakefulness but who report retrospectively experience of analgesia during severe parasomnia

    Background. Health outcomes are often contingent on how effective the individual is able to manage existent illness-related symptoms. This is all the more relevant among chronic pain patients. Objective. This study aimed to identify indicators of pain treatment satisfaction among middle-aged and older adults (N = 150) receiving outpatient treatment from a comprehensive cancer center. Methods. Patients were surveyed on questions assessing pain treatment satisfaction, pain severity, and additional social characteristics. Results. Descriptive data showed that middle-aged adults reported more pain locations, greater pain severity, and less satisfaction with pain treatment. A multivariate model was specified, showing older adults being more satisfied with their pain treatment. For the middle-aged adults, treatment satisfaction was generally lower with greater pain severity. This counters that for the older adults, where treatment satisfaction remained consistent despite increased levels of pain severity. Conclusion. These findings address an important issue regarding how pain is experienced across the life course. This suggests that general assumptions cannot be made about the health outcomes of older adults. Beyond the descriptive definitions of pain, there remains the need to develop models that account for determinants that may account for the pain experience among a diverse adult population.

    The prevalence of neuropathic low back pain differs in different ethnic populations. The aims of the study are to determine its frequency and associations in a multi-ethnic cohort of Asian low back pain patients. This was a cross-sectional study of low back patients seen at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia. Neuropathic low back pain patients were identified using the painDETECT questionnaire and compared with non-neuropathic (unclear or nociceptive) low back pain patients, in terms of socio-demographic and clinical factors, pain severity (numerical pain rating scale, NPRS), disability (Roland Morris Disability Questionnaire, RMDQ), as well as anxiety and depression (Hospital Anxiety and Depression Scale, HADS). Of 210 patients, 26 (12.4%) have neuropathic low back pain. Neuropathic pain is associated with non-Chinese ethnicity, higher body mass index and pain radiation below the knee. Patients with neuropathic pain have significantly higher NPRS and RMDQ scores, and there are more subjects with anxiety on HADS. However, there are no differences between the groups in age, gender, pain duration or underlying diagnosis of low back pain. The prevalence of neuropathic low back pain in a multi-ethnic Malaysian cohort is lower than previously reported in other populations with possible differences between ethnic groups. It is associated with greater pain severity, disability and anxiety.

Methods Retrospective review of patient data from a 3.5-year period. Results Fifteen percent (66/439) of all referrals to our pain service were for NP (56/323 patients, 17%; 34 male, 22 female). The NP patient group had 1401 clinical visits (778 inpatient visits [55.5%] and 623 outpatient visits [44.5%]). Patients with NP had a significantly greater mean number of pain visits per consult (p=0.008) and significantly more days (median) of pain service follow-up (p <0.001) than did other patients. The most common cause of NP was cancer treatment rather than the underlying malignancy. Pharmacological management of NP was complex, often comprising 3 medications. Nonpharmacological approaches were used for 57.6% of NP referrals. Discussion NP is less frequently encountered than non-NP in children with cancer; nevertheless, it is more difficult to treat, requiring longer follow up, more clinical visits, complex pharmacological management, and the frequent addition of non-pharmacological interventions.

    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.

  7. Verbally reinforcing pain reports: an experimental test of the operant model of chronic pain.

    2004-01-01

    Effective treatments for chronic pain have been based on the operant model for chronic pain, which holds that pain behaviours can be operantly controlled by various reinforcers. Support for the operant model comes primarily from treatment/outcome studies which report significant reductions in pain behaviours in chronic pain patients, but fail to demonstrate the underlying operant thesis that various reinforcers play a significant role in the establishment and maintenance of pain behaviours. In an experimental test of this hypothesis, the pain reports of forty-six healthy undergraduate students were measured over two sets of fifteen trials, in which the pressure from a blood-pressure cuff applied to their arm either remained stable or decreased over time. Half of the subjects received positive verbal reinforcement from the experimenter after each trial if their report of pain intensity exceeded that of the previous trial. Overall, the mean pain reports of reinforced subjects were significantly greater than those of the non-reinforced subjects both when the intensity of the cuff was stable over trials, and when it decreased, as expected. These results provide support for the operant model of chronic pain. The clinical and theoretical implications of these results for the operant model of chronic pain are discussed, and suggestions for future research are made.

  8. Pain complaint and the weather: weather sensitivity and symptom complaints in chronic pain patients.

    Chronic pain patients frequently report that weather conditions affect their pain; however, no standardized measures of weather sensitivity have been developed. We describe the development and use of the Weather and Pain Questionnaire (WPQ) which assess patient sensitivity to meteorologic variables defined by the National Weather Service (e.g., temperature, precipitation). Seventy chronic pain patients (59% females) with an average age of 43 years completed the WPQ. The instrument was revised using factor analysis to produce a Weather Sensitivity Index (WSI) (48% of variance) with high internal consistency (0.93) and test-retest reliability (r = 0.89). Reporting patterns suggested that patients could reliably identify which meteorologic variables influenced their pain but could not reliably determine which physical symptoms were consistently affected. The most frequently reported meteorologic variables which affect pain complaint were temperature (87%) and humidity (77%). The most frequently reported physical complaints associated with the weather were joint and muscle aches (82% and 79%, respectively). Patients labeled as being 'weather sensitive', defined by greater than median scores on the WPQ, reported significantly greater pain intensity, greater chronicity of pain problems, and more difficulties sleeping than patients with low scores on the WPQ. No differences in gender, education level, disability status, or global psychological distress were found. Results are discussed with respect to physiological and psychological mediating variables.

    Characterising the clinical course of back pain by mean pain scores over time may not adequately reflect the complexity of the clinical course of acute low back pain. We analysed pain scores over 12 weeks for 1585 patients with acute low back pain presenting to primary care to identify distinct pain trajectory groups and baseline patient characteristics associated with membership of each cluster. This was a secondary analysis of the PACE trial that evaluated paracetamol for acute low back pain. Latent class growth analysis determined a 5 cluster model, which comprised 567 (35.8%) patients who recovered by week 2 (cluster 1, rapid pain recovery); 543 (34.3%) patients who recovered by week 12 (cluster 2, pain recovery by week 12); 222 (14.0%) patients whose pain reduced but did not recover (cluster 3, incomplete pain recovery); 167 (10.5%) patients whose pain initially decreased but then increased by week 12 (cluster 4, fluctuating pain); and 86 (5.4%) patients who experienced high-level pain for the whole 12 weeks (cluster 5, persistent high pain). Patients with longer pain duration were more likely to experience delayed recovery or nonrecovery. Belief in greater risk of persistence was associated with nonrecovery, but not delayed recovery. Higher pain intensity, longer duration, and workers' compensation were associated with persistent high pain, whereas older age and increased number of episodes were associated with fluctuating pain. Identification of discrete pain trajectory groups offers the potential to better manage acute low back pain.

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

    PubMed Central

    Elsenbruch, Sigrid; Wolf, Oliver T.

    2015-01-01

    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.

    Greater levels of conscientiousness have been associated with lower levels of negative affect. We focus on one mechanism through which conscientiousness may decrease negative affect: effective emotion regulation, as reflected by greater recovery from negative stimuli. In 273 adults who were 35-85 years old, we collected self-report measures of personality including conscientiousness and its self-control facet, followed on average 2 years later by psychophysiological measures of emotional reactivity and recovery. Among middle-aged adults (35-65 years old), the measures of conscientiousness and self-control predicted greater recovery from, but not reactivity to, negative emotional stimuli. The effect of conscientiousness and self-control on recovery was not driven by other personality variables or by greater task adherence on the part of high conscientiousness individuals. In addition, the effect was specific to negative emotional stimuli and did not hold for neutral or positive emotional stimuli.

    Chronic postoperative pain remains a frequent pathology whose global impact approximates 20 and 30% and accounts for 20% of the consultations in a pain center. Risk factors consider firstly each patient's feature and comorbidity and also different surgical procedures with their technical approach. Neuropathic pain compared to nociceptive pain is a great component in the postoperative period and needs to be recognized by specific tests (DN4). Pain prevention involves risk factors' detection, appropriate anesthetic support and effective postoperative pain management. Treatment is based on the type of pain and includes a multimodal analgesia with interventional pain therapy.

    Central poststroke pain (CPSP) is characterized by hemianesthesia associated with unrelenting chronic pain. The final pain experience stems from interactions between sensory, affective, and cognitive components of chronic pain. Hence, managing CPSP will require integrated approaches aimed not only at the sensory but also the affective-cognitive spheres. A better understanding of the brain's processing of pain anticipation is critical for the development of novel therapeutic approaches that target affective-cognitive networks and alleviate pain-related disability. We used magnetoencephalography (MEG) to characterize the neural substrates of pain anticipation in patients suffering from intractable CPSP. Simple visual cues evoked anticipation while patients awaited impending painful (PS), nonpainful (NPS), or no stimulus (NOS) to their nonaffected and affected extremities. MEG responses were studied at gradiometer level using event-related fields analysis and time-frequency oscillatory analysis upon source localization. On the nonaffected side, significantly greater responses were recorded during PS. PS (vs. NPS and NOS) exhibited significant parietal and frontal cortical activations in the beta and gamma bands, respectively, whereas NPS (vs. NOS) displayed greater activation in the orbitofrontal cortex. On the affected extremity, PS (vs. NPS) did not show significantly greater responses. These data suggest that anticipatory phenomena can modulate neural activity when painful stimuli are applied to the nonaffected extremity but not the affected extremity in CPSP patients. This dichotomy may stem from the chronic effects of pain on neural networks leading to habituation or saturation. Future clinically effective therapies will likely be associated with partial normalization of the neurophysiological correlates of pain anticipation.

  1. Pain-Related Fear, Disability, and the Fear-Avoidance Model of Chronic Pain

    2015-01-01

    Chronic pain is a significant public health concern that imposes substantial burdens on individuals and healthcare systems, and factors that contribute to the development and maintenance of pain-related disability are of increasing empirical and clinical interest. Consistent with the fear-avoidance model of chronic pain, greater pain-related fear has consistently been associated with more severe disability and may predict the progression of disability over time. Recent evidence indicates that treatments designed to reduce pain-related fear are efficacious for improving disability outcomes, and several clinical trials are currently underway to test tailored intervention content and methods of dissemination. Future research in this area is needed to identify factors (e.g., substance use, comorbid psychopathology) that may influence interrelations between pain-related fear, response to treatment, and disability.

    In the postoperative period, 47% to 75% of the patients report some degree of pain. This study aimed to evaluate pain in the pre and postoperative period of patients submitted to craniotomy. This prospective research was carried out at the neurosurgery unit of a large Brazilian hospital. For a quantitative evaluation of pain, the verbal numeric 0-10 rating scale was used. Forty patients with a mean age of 36 years were evaluated. In the preoperative period, 34 (85%) patients indicated headache as the main cause of pain. In the postoperative period, 37 (93%) patients complained of pain while three (7%) reported absence of pain. Pain peaks were observed on the 2nd postoperative day, when 12 (32%) of the patients reported severe pain and 10 (27%) moderate pain. Absence of severe pain occurred after the 8th postoperative day. It was concluded that protocols of analgesia in craniotomy are needed, such as training nurses to better evaluate and handle pain.

    This paper is a summary of presentations on postoperative pain control by the authors at the 2014 PainForum meeting in People’s Republic of China. Postoperative pain is often untreated or undertreated and may lead to subsequent chronic pain syndromes. As more procedures migrate to the outpatient setting, postoperative pain control will become increasingly more challenging. Evidence-based guidelines for postoperative pain control recommend pain assessment using validated tools on a consistent basis. In this regard, consistency may be more important than the specific tool selected. Many hospitals have introduced a multidisciplinary acute pain service (APS), which has been associated with improved patient satisfaction and fewer adverse events. Patient education is an important component of postoperative pain control, which may be most effective when clinicians chose a multimodal approach, such as paracetamol (acetaminophen) and opioids. Opioids are a mainstay of postoperative pain control but require careful monitoring and management of side effects, such as nausea, vomiting, dizziness, and somnolence. Opioids may be administered using patient-controlled analgesia systems. Protocols for postoperative pain control can be very helpful to establish benchmarks for pain management and assure that clinicians adhere to evidence-based standards. The future of postoperative pain control around the world will likely involve more and better established APSs and greater communication between patients and clinicians about postoperative pain. The changes necessary to implement and move forward with APSs is not a single step but rather one of continuous improvement and ongoing change. PMID:26893579

    Objective and Method Research on emotion and pain has burgeoned. We review the last decade’s literature, focusing on links between emotional processes and persistent pain. Results Neurobiological research documents the neural processes that distinguish affective from sensory pain dimensions, link emotion and pain, and generate central nervous system pain sensitization. Psychological research demonstrates that greater pain is related to emotional stress and limited emotional awareness, expression, and processing. Social research shows the potential importance of emotional communication, empathy, attachment, and rejection. Conclusions Emotions are integral to the conceptualization, assessment, and treatment of persistent pain. Research should clarify when to eliminate or attenuate negative emotions, and when to access, experience, and express them. Theory and practice should integrate emotion into cognitive-behavioral models of persistent pain. PMID:21647882

    The study used a daily process design to examine the role of psychological resilience and positive emotions in the day-to-day experience of pain catastrophizing. A sample of 95 men and women with chronic pain completed initial assessments of neuroticism, psychological resilience, and demographic data, and then completed short diaries regarding pain intensity, pain catastrophizing, and positive and negative emotions every day for 14 consecutive days. Multilevel modeling analyses indicated that independent of level of neuroticism, negative emotions, pain intensity, income, and age, high-resilient individuals reported greater positive emotions and exhibited lower day-to-day pain catastrophizing compared with low-resilient individuals. Mediation analyses revealed that psychologically resilient individuals rebound from daily pain catastrophizing through experiences of positive emotion. Implications for research on psychological resilience, pain catastrophizing, and positive emotions are discussed.

    Objective This study seeks to establish the efficacy of single-lead, 3-week peripheral nerve stimulation (PNS) therapy for pain reduction in stroke survivors with chronic hemiplegic shoulder pain. Design Single-site, pilot, randomized controlled trial for adults with chronic shoulder pain after stroke. Participants were randomized to receive a 3-week treatment of single-lead PNS or usual care (UC). The primary outcome was the worst pain in the last week (Brief Pain Inventory, Short Form question 3) measured at baseline, and weeks 1,4, 12, and 16. Secondary outcomes included pain interference (Brief Pain Inventory, Short Form question 9), pain measured by the ShoulderQ Visual Graphic Rating Scales; and health-related quality of life (SF-36v2). Results Twenty-five participants were recruited, 13 to PNS and 12 to UC. There was a significantly greater reduction in pain for the PNS group compared to controls, with significant differences at 6 and 12 weeks after treatment. Both PNS and UC were associated with significant improvements in pain interference and physical health related quality of life. Conclusions Short-term PNS is a safe and efficacious treatment for shoulder pain. Pain reduction is greater than compared to UC and is maintained for at least 12 weeks after treatment. PMID:24355994

  7. Pain management in neonates.

    2004-05-01

    Multiple lines of evidence suggest an increased sensitivity to pain in neonates. Repeated and prolonged pain exposure may affect the subsequent development of pain systems, as well as potentially contribute to alterations in long-term development and behavior. Despite impressive gains in the knowledge of neonatal pain mechanisms and strategies to treat neonatal pain acquired during the last 15 years, a large gap still exists between routine clinical practice and research results. Accurate assessment of pain is crucial for effective pain management in neonates. Neonatal pain management should rely on current scientific evidence more than the attitudes and beliefs of care-givers. Parents should be informed of pain relief strategies and their participation in the health care plan to alleviate pain should be encouraged. The need for systemic analgesia for both moderate and severe pain, in conjunction with behavioral/environmental approaches to pain management, is emphasized. A main sources of pain in the neonate is procedural pain which should always be prevented and treated. Nonpharmacological approaches constitute important treatment options for managing procedural pain. Nonpharmacological interventions (environmental and preventive measures, non-nutritive sucking, sweet solutions, skin-skin contact, and breastfeeding analgesia) can reduce neonatal pain indirectly by reducing the total amount of noxious stimuli to which infants are exposed, and directly, by blocking nociceptive transduction or transmission or by activation of descending inhibitory pathways or by activating attention and arousal systems that modulate pain. Opioids are the mainstay of pharmacological pain treatment but there are other useful medications and techniques that may be used for pain relief. National guidelines are necessary to improve neonatal pain management at the institutional level, individual neonatal intensive care units need to develop specific practice guidelines regarding pain

    2011-01-01

    Objectives Persistent pain is associated with poorer health outcomes and may lead to increased vulnerability and diminished physiologic reserve, ultimately precipitating frailty. To test for the existence of this process, we compared the association of self-reported moderate to severe pain with the presence of frailty. Design Cross-sectional analysis of the Canadian Study of Health and Aging-Wave 2. Setting Community dwellers Participants Representative sample of persons age 65 and older in Canada. Measurements Pain (exposure) was categorized as no or very mild pain versus moderate or greater pain. Frailty (outcome) was operationalized as the accumulation of 33 possible self-reported health attitudes, illnesses, and functional abilities, subsequently divided into tertiles (i.e. not frail, pre-frail, and frail). Multivariable logistic regression assessed for the association of pain with frailty. Results Of participants who reported moderate or greater pain (35.5% or 1,765 out of 4,968), 16.2% were not frail, 34.1% were pre-frail, and 49.8%were frail. For persons with moderate or greater pain compared to those with mild or no pain, the odds of being pre-frail compared to not frail were higher by a factor of 2.52 (95% confidence interval (CI)=2.13-2.99; p<0.05). For persons with moderate or greater pain compared to those with mild or no pain, the odds of being frail compared to not frail was higher by a factor of 5.52 (CI=4.49-6.64; p<0.05). Conclusion Moderate or higher pain was independently associated with the presence of frailty. While we cannot ascertain causality in a cross-sectional analysis, interventions to improve pain management may help prevent or ameliorate frailty. PMID:22150394

    We studied the highest reported number of patients with occult fracture of the greater tuberosity of the humerus and we analysed why fracture was not diagnosed, shoulder function and prevalence of eventually associated rotator cuff tear (RCT). Twenty-four patients with a missed fracture of the greater tuberosity underwent MR study for a suspect RCT. We evaluated shoulder function and self-assessed comfort with the Constant score (CS) and Simple Shoulder Test (SST). Nine patients showed evidence of cuff tendinosis, 11 of partial (p) RCT (2: subscapularis; 6: supraspinatus and 3: supraspinatus and infraspinatus). All patients with pRCT were older than 40. Initially, the mean CS and SST were 54% and 5/12; at follow-up, values increased to 36% and 5 points. MR should be performed in patients apparently negative for fracture but with painful shoulders and decreased ROM. Of our patients, 45.8% had pRCT; nevertheless function recovery was verified in 16 weeks.

    Pain has been considered as part of a defensive strategy whose specific role is to signal an immediate active danger to the organism. This definition fits well for acute pain. It does not work well, however, for chronic pain that is maintained even in absence of an ongoing, active threat. Currently, acute and chronic pain are considered to be separate conditions. What follows is a review of the different theories about pain and its history. Different hypotheses regarding pain mechanisms are illustrated. New data emerging from scientific research on chronic pain (migraine in particular) involving innovative imaging techniques are reported and discussed.

    2015-01-01

    Recent data demonstrate that dry eye (DE) susceptibility and other chronic pain syndromes (CPS) such as chronic widespread pain, irritable bowel syndrome and pelvic pain, may share common heritable factors. Previously, we showed that DE patients describing more severe symptoms tended to report features of neuropathic ocular pain (NOP). We hypothesize that patients with a greater number of CPS would have a different DE phenotype compared to those with fewer CPS. We recruited a cohort of 154 DE patients from the Miami Veterans Affairs Hospital and defined high and low CPS groups by cluster analysis. In addition to worse non-ocular pain complaints and higher PTSD and depression scores (P<0.01), we found that the high CPS group reported more severe neuropathic-type DE symptoms compared to the low CPS group, including worse ocular pain assessed via 3 different pain scales (P<0.05), with similar objective corneal DE signs. This is the first study to demonstrate DE patients who manifest a greater number of comorbid CPS report more severe DE symptoms and features of NOP. These findings provide further evidence that NOP may represent a central pain disorder, and that shared mechanistic factors may underlie vulnerability to some forms of DE and other comorbid CPS.

    There is mounting evidence of long-lasting changes in pain sensitivity in school-age children who were cared for in a neonatal intensive care unit. Such care involves multiple pain exposures, 70% of which are accounted for by heel lance to monitor physiological well-being. The authors sought to model the repeated brief pain resulting from heel lance by administering repeated paw needle stick to neonatal rat pups. Repeated needle stick during the first 8 days of life was sex-specific in altering responses to mechanical and inflammatory stimuli, but not to a thermal stimulus, at maturity. Specifically, neonatal paw needle stick males exhibited significantly greater mechanical sensitivity in response to von Frey hair testing, whereas neonatal paw needle stick females exhibited significantly greater pain behavior scores following hindpaw formalin injection. This is the first study to show such sex-dependent changes in pain responsiveness at maturity in animals having experienced repeated neonatal needle stick pain. These findings support existing evidence that there are long-term sensory sequelae following neonatal pain experiences in rats and further suggest that there are sex-linked differences in the nature of the consequences. If these relationships hold in humans, these findings suggest that even mild painful insults early in life are not without sensory consequences.

    In this study, we utilize plate tectonic history of Central Asia to constrain understanding of sedimentary basin development and to show how regional scale tectonic events affect play elements for major basins of greater China. Tectonic framework and paleogeography are used as a constraint on models for basin formation, climate distribution and accommodation which in turn control distribution of reservoir, source, seal and trap. Greater China is an artifact of Phanerozoic tectonics. It has a protracted history of continental deformation as amalgamation of crustal blocks and island arc/subduction and accretion complexes occurred. Early Paleozoic hydrocarbon systems are dominated by extensive carbonate platform and Permian and younger systems are dominated by continental and lacustrine sedimentation. The basement of greater China consists of continental and accretion crust. The crustal blocks include South and North China, Indochina, Tibet and Tarim, and accretion blocks include the Altaids and Manchurides. The relative positions and interactions of these blocks during Paleozic and Mesozoic time resulted in formation of greater China. Final amalgamation and deformation occurred in Eocene time when India collided with Asia. The discussions consist of presentation of a model for tectonic evolution of these blocks and their paleogeography through Phanerozoic time. This is done with maps at 1:8 million scale covering nine time slices, three in the Paleozoic, three in the Mesozoic and three in the Cenozoic.

    Despite the availability of effective pain treatments, there are numerous barriers to effective management resulting in a large proportion of patients not achieving optimal pain control. Chronic pain is inadequately treated because of a combination of cultural, societal, educational, political and religious constraints. The consequences of inadequately treated pain are physiological and psychological effects on the patient, as well as socioeconomic implications. Unreasonable failure to treat pain is viewed as unethical and an infringement of basic human rights. The numerous barriers to the clinical management of pain vary depending on whether they are viewed from the standpoint of the patient, the physician, or the institution. Identification and acknowledgement of the barriers involved are the first steps to overcoming them. Successful initiatives to overcome patient, physician and institutional barriers need to be multifaceted in their approach. Multidisciplinary initiatives to improve pain management include dissemination of community-based information, education and awareness programmes to attempt to change attitudes towards pain treatment. A better awareness and insight into the problems caused by unrelieved pain and greater knowledge about the efficacy and tolerability of available pain management options should enable physicians to seek out and adhere to treatment guidelines, and participate in interventional and educational programmes designed to improve pain management, and for institutions to implement the initiatives required. Although much work is underway to identify and resolve the issues in pain management, many patients still receive inadequate treatment. Continued effort is required to overcome the known barriers to effective pain management.

    The processing of noxious and non-noxious sensations differs between chronic pain syndromes, and we believe that studies of sensory processing in the presence of pain will help to clarify the aetiology of the conditions. Here we measured in humans the threshold-level mechanosensitivity in tonic experimental muscle pain. We found (1) that muscle pain induced by hypertonic saline reduced cutaneous threshold-level mechanosensitivity at the site of pain and at the mirror site in the contralateral face, (2) that this effect outlasted the sensation of pain, (3) that it was more pronounced when the painful area was reported to be large, and (4) that the loss of mechanosensitivity was greater in males than females. Comparing our findings to results obtained with other pain models, all classes of nociceptors do not seem to have the same effect on cutaneous mechanosensitivity. The observed threshold-level hypoesthesia is consistent with the hypothesis that the increased mechanical thresholds found in clinic cases of temporomandibular disorders and cervicobrachialgia are a direct result of the activation of muscle nociceptors.

    Several cognitive-affective constructs, including pain catastrophizing and pain-related anxiety, have been implicated in the onset and progression of chronic pain, and both constructs have been identified as key targets for multidisciplinary pain treatment. Both neuroticism and depression have been linked to these constructs (and to each other), but how each may contribute to the pain experience is unknown. This study tested associations between neuroticism, depression, and indices of catastrophizing and pain-related anxiety among persons seeking treatment for chronic non-malignant pain. We hypothesized, as a higher-order personality trait, neuroticism would remain uniquely associated with both pain catastrophizing and pain-related anxiety, even after accounting for current symptoms of depression. A retrospective study design assessed depression (as measured by the Centers for Epidemiologic Studies-Depression scale), neuroticism (measured with the Neuroticism-Extraversion-Openness Personality Inventory), the Pain Catastrophizing Scale, and the Pain Anxiety Symptom Score in a consecutive series of patients (n=595) admitted to a 3-week outpatient pain treatment program from March 2009 through January 2011. Hierarchical regression indicated that neuroticism was independently associated with greater pain catastrophizing and pain-related anxiety, above-and-beyond the contributions of sociodemographic characteristics, pain severity, and depression. A depression by neuroticism interaction was not observed, suggesting that associations between neuroticism and cognitive-affective pain constructs remained stable across varying levels of current depression. These findings represent an early but important step towards the clarification of complex associations between trait neuroticism, current depression, and tendencies toward catastrophic and anxiety-provoking appraisals of pain among persons seeking treatment for chronic pain.

    Objectives To describe and understand varieties and characteristics of sensitization contributing to hyperalgesia for patients with chronic pain conditions. Methods Thermal stimulation was delivered to the face, forearm and calf of pain-free subjects and individuals with irritable bowel syndrome (IBS), temporomandibular pain disorder (TMD) and fibromyalgia syndrome (FMS). Three second contacts of a preheated thermode occurred at 30 sec. intervals in ascending and then descending series (0.7°C steps). Results Thermal pain ratings during ascending series were greater at each site for individuals diagnosed with chronic pain. Strong pain at the time of testing further enhanced the ratings at all sites, but mild or moderate clinical pain did not have this effect. Thermal pain for all subjects was greater during descending series than during ascending series of arm and leg stimulation. The hypersensitivity during descending series was comparable for pain-free, FMS and TMD subjects but was increased in duration for arm or leg stimulation of FMS subjects. Discussion The widespread sensitization for IBS and TMD subjects does not rely on mechanisms of spatial and temporal summation often invoked to explain widespread hyperalgesia associated with chronic pain. Increased sensitivity during descending series during stimulation of an arm or leg but not the face indicates a propensity for sensitization of nociceptive input to the spinal cord. Abnormally prolonged sensitization for FMS patients reveals a unique influence of widespread chronic pain referred to deep somatic tissues. PMID:23629594

    Purpose This preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain. Methods Test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (ICC), standard error of measurements (SEMs), coefficient of variation (CV), and one-way repeated measures ANOVA using the values collected from 13 young individuals (25.8 ± 6.2 years) with chronic non-specific low back pain on two occasions separated by 2 days. Percent agreement of the ordinal data was also determined by Cohen's Kappa statistics (kappa). The measures consisted of tissue blood flow (BF), average pain visual analog scales (VAS), pressure pain threshold (PPT), cold pain threshold (CPT), heat pain threshold (HPT) and lumbo-pelvic stability test (LPST). An acceptable reliability was determined as the ICC values of greater than 0.85, SEMs less than 5%, CV less than 15%, the kappa scores of greater than 80% and no evidence of systematic error (ANOVA, P>0.05). Results ICC of all measures in the lumbo-sacral area were greater than 0.87. The kappa was also greater than 83%. Most measures demonstrated a minimal error of measurements and less potential of systemic error in nature. Only the SEMs and the CV of the CPT exceeded the acceptable level. Conclusions It is concluded that most of the quantitative measurements are reliable for the study of non-specific low back pain, however the CPT should be applied with care as it has a great variation among individuals and potential of measurement error.

    ABSTRACT Objective Hypnotic suggestion is an empirically validated form of pain control; however, the underlying mechanism remains unclear. Methods Thirteen fibromyalgia patients received suggestions to alter their clinical pain, and 15 healthy controls received suggestions to alter experimental heat pain. Suggestions were delivered before and after hypnotic induction with blood oxygen level–dependent (BOLD) activity measured concurrently. Results Across groups, suggestion produced substantial changes in pain report (main effect of suggestion, F2, 312 = 585.8; p < .0001), with marginally larger changes after induction (main effect of induction, F1, 312 = 3.6; p = .060). In patients, BOLD response increased with pain report in regions previously associated with pain, including thalamus and anterior cingulate cortex. In controls, BOLD response decreased with pain report. All changes were greater after induction. Region-of-interest analysis revealed largely linear patient responses with increasing pain report. Control responses, however, were higher after suggestion to increase or decrease pain from baseline. Conclusions Based on behavioral report alone, the mechanism of suggestion could be interpreted as largely similar regardless of the induction or type of pain experience. The functional magnetic resonance imaging data, however, demonstrated larger changes in brain activity after induction and a radically different pattern of brain activity for clinical pain compared with experimental pain. These findings imply that induction has an important effect on underlying neural activity mediating the effects of suggestion, and the mechanism of suggestion in patients altering clinical pain differs from that in controls altering experimental pain. Patient responses imply that suggestions altered pain experience via corresponding changes in pain-related brain regions, whereas control responses imply suggestion engaged cognitive control.

    Migraine is a pain disorder associated with abnormal brain structure and function, yet the effect of migraine on acute pain processing remains unclear. It also remains unclear whether altered pain-related brain responses and related structural changes are associated with clinical migraine characteristics. Using fMRI and three levels of thermal stimuli (non-painful, mildly painful, and moderately painful), we compared whole-brain activity between 14 migraine patients and 14 matched controls. Although, there were no significant differences in pain thresholds nor in pre-scan pain ratings to mildly painful thermal stimuli, patients did have aberrant suprathreshold nociceptive processing. Brain imaging showed that, compared to controls, patients had reduced activity in pain modulatory regions including left dorsolateral prefrontal, posterior parietal, and middle temporal cortices and, at a lower-threshold, greater activation in the right mid-insula to moderate pain vs. mild pain. We also found that pain-related activity in the insula was associated with clinical variables in patients, including associations between: bilateral anterior insula and pain catastrophizing (PCS); bilateral anterior insula and contralateral posterior insula and migraine pain intensity; and bilateral posterior insula and migraine frequency at a lower-threshold. PCS and migraine pain intensity were also negatively associated with activity in midline regions including posterior cingulate and medial prefrontal cortices. Diffusion tensor imaging revealed a negative correlation between fractional anisotropy (a measure of white matter integrity; FA) and migraine duration in the right mid-insula and a positive correlation between left mid-insula FA and PCS. In sum, while patients showed lower sensitivity to acute noxious stimuli, the neuroimaging findings suggest enhanced nociceptive processing and significantly disrupted modulatory networks, particularly involving the insula, associated with indices

    STUDY QUESTION What are the pain characteristics among women, with no prior endometriosis diagnosis, undergoing laparoscopy or laparotomy regardless of clinical indication? SUMMARY ANSWER Women with surgically visualized endometriosis reported the highest chronic/cyclic pain and significantly greater dyspareunia, dysmenorrhea, and dyschezia compared with women with other gynecologic pathology (including uterine fibroids, pelvic adhesions, benign ovarian cysts, neoplasms and congenital Müllerian anomalies) or a normal pelvis. WHAT IS KNOWN ALREADY Prior research has shown that various treatments for pain associated with endometriosis can be effective, making identification of specific pain characteristics in relation to endometriosis necessary for informing disease diagnosis and management. STUDY DESIGN, SIZE, DURATION The study population for these analyses includes the ENDO Study (2007–2009) operative cohort: 473 women, ages 18–44 years, who underwent a diagnostic and/or therapeutic laparoscopy or laparotomy at one of 14 surgical centers located in Salt Lake City, UT or San Francisco, CA. Women with a history of surgically confirmed endometriosis were excluded. PARTICIPANTS/MATERIALS, SETTING AND METHODS Endometriosis was defined as surgically visualized disease; staging was based on revised American Society for Reproductive Medicine (rASRM) criteria. All women completed a computer-assisted personal interview at baseline specifying 17 types of pain (rating severity via 11-point visual analog scale) and identifying any of 35 perineal and 60 full-body front and 60 full-body back sites for which they experienced pain in the last 6 months. MAIN RESULTS AND THE ROLE OF CHANCE There was a high prevalence (≥30%) of chronic and cyclic pelvic pain reported by the entire study cohort regardless of post-operative diagnosis. However, women with a post-operative endometriosis diagnosis, compared with women diagnosed with other gynecologic disorders or a normal pelvis

    Background Parental behaviors, emotions, and cognitions are known to influence children’s response to pain. However, prior work has not tested the association between maternal psychological factors and children’s responses to a conditioned pain modulation (CPM) task. CPM refers to the reduction in perceived pain intensity for a test stimulus following application of a conditioning stimulus to a remote area of the body, and is thought to reflect the descending inhibition of nociceptive signals. Methods The present study examined sex differences in the association between maternal anxiety about pain and children’s CPM responses in 133 healthy children aged 8–17 years. Maternal pain anxiety was assessed using the Pain Anxiety Symptoms Scale-20. In addition to the magnitude of CPM, children’s anticipatory anxiety and pain-related fear of the CPM task were measured. Results Sequential multiple linear regression revealed that even after controlling for child age and general maternal psychological distress, greater maternal pain anxiety was significantly related to greater CPM anticipatory anxiety and pain-related fear in girls, and to less CPM (ie, less pain inhibition) in boys. Conclusion The findings indicate sex-specific relationships between maternal pain anxiety and children’s responses to a CPM task over and above that accounted for by the age of the child and the mother’s general psychological distress.

    Although body awareness and pain perception are considered to be parts of the interoceptive system, the relationship between them is unclear. This study examines the association between body awareness and pain habituation, hypothesizing that this association is moderated by pain catastrophizing and mindfulness. Sixty subjects received a mildly aversive electrical stimulus for 60 s, during which they were requested to rate the amount of perceived pain. Complete habituation was indicated by abolition of pain sensation; partial habituation was indicated by a decrease in pain sensation. Individuals who demonstrated complete habituation had lower levels of pain catastrophizing and lower levels of mindfulness. As hypothesized, the association between body awareness and pain habituation was moderated by pain catastrophizing: Among low pain catastrophizers, the higher the body awareness, the stronger the tendency to exhibit complete habituation. Among high pain catastrophizers, the higher the body awareness, the greater the likelihood to present partial habituation.

    2007-06-01

    Understanding the relationships between spirituality and health has become increasingly important in health research, including nursing research. Very little of the research thus far has focused on spirituality, religion, and pain even though spiritual views have been intertwined with beliefs about pain and suffering throughout history. Spiritual views can have a substantial impact on patients' understanding of pain and decisions about pain management. The author reviews the research literature on spirituality and pain from a historical perspective. The analysis is concerned with how spirituality and religion have been used to construct a meaning of pain that shapes appraisal, coping, and pain management. The clinical implications include respectful communication with patients about spirituality and pain, inclusion of spirituality in education and support programs, integration of spiritual preferences in pain management where feasible and appropriate, consultation with pastoral care teams, and reflection by nurses about spirituality in their own lives. A discussion of research implications is included.

  15. Pain, objectivity and history: understanding pain stigma.

    PubMed

    Goldberg, Daniel S

    2017-02-21

    The primary claim of this paper is that understanding the stigma so commonly endured by chronic pain sufferers today in the USA and the UK is unlikely without proper appreciation of the history of pain. Ameliorating such stigma is an ethical imperative, and yet most approaches eschew even an attempt to trace connections between historical attitudes, practices and beliefs towards pain and the stigmatisation so many pain sufferers currently endure. The manuscript aims to help fill this gap by framing pain in the modern era in context of two crucial intellectual schemes that waxed in the 19th and 20th centuries: mechanical objectivity and somaticism. The analysis explains these frameworks and applies them to exploration of primary sources connected to contested pain conditions such as railway spine. By properly situating the historical roots of what it means to cite the 'subjectivity' of pain as a problem, the modern roots of stigmatising attitudes and practices towards chronic pain sufferers become much clearer. The manuscript concludes by suggesting that interventions expressly intended to target the root causes of such stigma are much more likely to be successful than approaches that proceed in ignorance of the historical forces shaping and driving pain stigma in the present.

    The painful events associated with the treatment of a severe burn can, because of their long-lasting and repetitive characteristics, be one of the most excruciating experiences in clinical practice. Moreover, burn pain has been shown to be detrimental to burn patients. Although nociception and peripheral hyperalgesia are considered the major causes of burn pain, the study of more hypothetical mechanisms like central hyperalgesia and neuropathic pain may lead to a better understanding of burn pain symptoms and to new therapeutic approaches. Continuous pain and intermittent pain due to therapeutic procedures are two distinct components of burn pain. They have to be evaluated and managed separately. Although continuous pain is by far less severe than intermittent pain, the treatment is, in both cases, essentially pharmacological relying basically on opioids. Because of wide intra- and inter-individual variations, protocols will have to leave large possibilities of adaptation for each case, systematic pain evaluation being mandatory to achieve the best risk/benefit ratio. Surprisingly, the dose of medication decreases only slowly with time, a burn often remaining painful for long periods after healing. Non pharmacological treatments are often useful and sometimes indispensable adjuncts; but their rationale and their feasibility depends entirely on previous optimal pharmacological control of burn pain. Several recent studies show that burn pain management is inadequate in most burn centres.

    The purpose of this study was to describe the types of pain information described by older adults with chronic osteoarthritis pain. Pain descriptions were obtained from older adults’ who participated in a posttest only double blind study testing how the phrasing of healthcare practitioners’ pain questions affected the amount of communicated pain information. The 207 community dwelling older adults were randomized to respond to either the open-ended or closed-ended pain question. They viewed and orally responded to a computer displayed videotape of a practitioner asking them the respective pain question. All then viewed and responded to the general follow up question, ““What else can you tell me?” and lastly, “What else can you tell me about your pain, aches, soreness or discomfort?” Audio-taped responses were transcribed and content analyzed by trained, independent raters using 16 a priori criteria from the American Pain Society (2002) Guidelines for the Management of Pain in Osteoarthritis, Rheumatoid Arthritis, and Juvenile Chronic Arthritis. Older adults described important but limited types of information primarily about pain location, timing, and intensity. Pain treatment information was elicited after repeated questioning. Therefore, practitioners need to follow up older adults’ initial pain descriptions with pain questions that promote a more complete pain management discussion. Routine use of a multidimensional pain assessment instrument that measures information such as functional interference, current pain treatments, treatment effects, and side effects would be one way of insuring a more complete pain management discussion with older adults.

    It is now recognized that from the newborn period onwards, children are capable of experiencing pain. This includes the premature infant. The challenge for healthcare providers is to incorporate methods of pain assessment and treatment into their daily practices. The child's understanding of pain closely follows the cognitive and behavioral model developed by Jean Piaget. Based on these developmental stages, pain assessment measures have been developed. Pharmacologic advances have accompanied this improved understanding of infant, child, and adolescent psychology. While acute pain accounts for the majority of children's experiences, recurrent/chronic pain states do occur (e.g. sickle cell related and neuropathic) and can be effectively treated.

    There has been great progress in the understanding of basic neurobiologic mechanisms of pain, but this body of knowledge has not yet translated into new and improved analgesics. Progress has been made regarding pain assessment in horses, but more work is needed until sensitive and accurate pain assessment tools are available for use in clinical practice. This review summarizes and updates the knowledge concerning the cornerstones of pain medicine (understand, assess, prevent, and treat). It highlights the importance of understanding pain mechanisms and expressions to enable a rational approach to pain assessment, prevention, and management in the equine patient.

    2010-01-01

    It has long been appreciated that the experience of pain is highly variable between individuals. Pain results from activation of sensory receptors specialized to detect actual or impending tissue damage (i.e., nociceptors). However, a direct correlation between activation of nociceptors and the sensory experience of pain is not always apparent. Even in cases in which the severity of injury appears similar, individual pain experiences may vary dramatically. Emotional state, degree of anxiety, attention and distraction, past experiences, memories, and many other factors can either enhance or diminish the pain experience. Here, we review evidence for “top-down” modulatory circuits that profoundly change the sensory experience of pain. PMID:21041960

    Quantitative sensory testing (QST) has been used to characterize pain sensitivity in individuals with and without pain conditions. Research remains limited in pediatric populations, hindering the ability to expand the utility of QST toward its potential application in clinical settings and clinical predictive value. The aims of this study were to examine pain sensitivity using QST in adolescents with chronic pain compared to adolescents without chronic pain and identify predictors of pain sensitivity. A population-based study conducted from 2010 to 2011 provided data on 941 adolescents, 197 were classified as having chronic pain and 744 were classified without chronic pain. Self-reported data on pain characteristics, psychological functioning, and QST responses were examined. The findings revealed lower pressure pain threshold and tolerance on the trapezius (P's = 0.03) in adolescents with chronic pain compared to adolescents without chronic pain, but no differences on heat or cold-pressor pain tasks. Female sex (P's = 0.02) and poorer psychological functioning (P's = 0.02) emerged as significant predictors of greater pain sensitivity across all pain modalities. Exploratory analyses revealed several associations between clinical pain characteristics and QST responses within the chronic pain cohort. Findings from this large pediatric sample provide comprehensive data that could serve as normative data on QST responses in adolescents with and without chronic pain. These findings lay the groundwork toward developing future QST research and study protocols in pediatric populations, taking into consideration sex and psychological distress.

    Children undergo acute painful procedures and many also experience chronic pain.Due to their developing systems, infants and children may be at greater risk than adults for protracted pain sensitivity.There is a need to manage acute and chronic paediatric pain to reduce children's suffering and to prevent future pain problems.Consistent with a biopsychosocial perspective, complementary and alternative medicine (CAM) should be considered in management of acute and chronic paediatric pain.Although research is limited for paediatric pain, CAM interventions receiving the most empirical attention include hypnotherapy, acupuncture and music therapy. Evidence also exists for the therapeutic benefits of yoga, massage, humor therapy and the use of certain biological based therapies.

    SUMMARY No single analgesic drug provides the perfect therapeutic/adverse effect profile for every pain condition. In addition to convenience and possibly improved compliance, a combination of analgesic drugs offers the potential, requiring verification, of providing greater pain relief and/or reduced adverse effects than the constituent drugs when used individually. We review here analgesic combinations containing oxycodone. We found surprisingly little preclinical information about the analgesic or adverse effect profiles of the combinations (with acetaminophen, paracetamol, nonsteroidal anti-inflammatory drugs, morphine, gabapentin or pregabalin). Clinical experience and studies suggest that the combinations are safe and effective and may offer certain advantages. As with all combinations, the profile of adverse effects must also be determined in order to provide the clinician with the overall benefit/risk assessment. PMID:20571607

    Objective Chronic pain is believed to be related to a dysfunction of descending pain modulatory mechanisms. Functioning of descending pain modulation can be assessed by various methods, including conditioned pain modulation (CPM). CPM refers to the inhibition of one source of pain by a second noxious stimulus, termed the conditioning stimulus. This procedure can activate an endogenous pain inhibitory mechanism that inhibits early nociceptive processing. Chronic pain and anxiety disorders are more prevalent among females and it has been hypothesized that females react with more negative emotions towards unpleasant stimuli and this might be part of the explanation of greater pain sensitivity in females. The present study investigated whether expectations modulate the effect of conditioning stimulation on pain, subjective stress, and heart rate. In addition, we investigated whether the modulation of CPM by expectations differed between males and females. Methods Seventy-two subjects (including 36 women) received six noxious heat stimuli to the forearm. During three of these stimuli, a conditioning stimulus (cold-water bath) was applied to the contralateral arm in order to activate CPM. One third of the subjects were told that this would reduce pain (analgesia group), one-third that it would increase pain (hyperalgesia group), and one third received no information about its effect (no info group). Results Information that conditioning stimulation decreased or enhanced pain had the corresponding effect in females, but not in males. Conditioning stimulation increased stress, but not heart rate in females in the hyperalgesia group. A higher expectation of analgesia and lower stress during conditioning stimulation was associated with larger inhibitory CPM. Conclusion These results suggest that reduced inhibitory CPM can be due to contextually induced cognitive and emotional factors and not necessarily a dysfunction of descending inhibitory pathways.

    Chronic pain represents one of the most important public health problems in terms of both the number of patients afflicted and health care costs. Most patients with chronic pain are treated with medications as the mainstay of therapy, and yet most medically treated patients continue to report ongoing pain. Additionally, adverse effects from pain medications represent a major challenge for clinicians and patients. Spinal cord stimulation and intrathecal drug delivery systems are well-established techniques that have been utilized for over 25 years. Intrathecal drug delivery systems have proven efficacy for a wide variety of intractable pain conditions and fewer adverse effects than systemic medical therapy in patients with refractory cancer-related pain. Spinal cord stimulation is cost-effective and provides improved pain control compared with medical therapy in patients with a variety of refractory pain conditions including complex regional pain syndrome, painful diabetic neuropathy, and chronic radiculopathy. Patients who have intractable pain that has not responded to reasonable attempts at conservative pain care measures should be referred to a qualified interventional pain specialist to determine candidacy for the procedures discussed in this article.

    Loin pain hematuria syndrome is a rare disease with a prevalence of ∼0.012%. The most prominent clinical features include periods of severe intermittent or persistent unilateral or bilateral loin pain accompanied by either microscopic or gross hematuria. Patients with loin pain hematuria syndrome initially present with hematuria, flank pain, or most often both hematuria and flank pain. Kidney biopsies from patients with loin pain hematuria typically reveal only minor pathologic abnormalities. Further, loin pain hematuria syndrome is not associated with loss of kidney function or urinary tract infections. Loin pain hematuria syndrome-associated hematuria and pain are postulated to be linked to vascular disease of the kidney, coagulopathy, renal vasospasm with microinfarction, hypersensitivity, complement activation on arterioles, venocalyceal fistula, abnormal ureteral peristalsis, and intratubular deposition of calcium or uric acid microcrystals. Many patients with loin pain hematuria syndrome also meet criteria for a somatoform disorder, and analgesic medications, including narcotics, commonly are used to treat loin pain hematuria syndrome-associated pain. Interventional treatments include renal denervation, kidney autotransplantation, and nephrectomy; however, these methods should be used only as a last resort when less invasive measures have been tried unsuccessfully. In this review article, we discuss and critique current clinical practices related to loin pain hematuria syndrome pathophysiology, diagnosis, treatment, and prognosis.

    The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and its habitats and to address the observed decreases in distribution and population numbers. The amount of research and management has increased as the year 2015 approaches, which is when the U.S. Fish and Wildlife Service (FWS) is expected to make a final decision about whether or not to protect the species under the Endangered Species Act. In 2012, the Sage-Grouse Executive Oversight Committee (EOC) of the Western Association of Fish and Wildlife Agencies (WAFWA) requested that the U.S. Geological Survey (USGS) lead the development of a Greater Sage-Grouse National Research Strategy (hereafter Research Strategy). This request was motivated by a practical need to systematically connect existing research and conservation plans with persisting or emerging information needs. Managers and researchers also wanted to reduce redundancy and help focus limited funds on the highest priority research and management issues. The USGS undertook the development of this Research Strategy, which addresses information and science relating to the greater sage-grouse and its habitat across portions of 11 Western States. This Research Strategy provides an outline of important research topics to ensure that science information gaps are identified and documented in a comprehensive manner. Further, by identifying priority topics and critical information needed for planning, research, and resource management, it provides a structure to help coordinate members of an expansive research and management community in their efforts to conduct priority research.

    Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. In this study we detail an accidental mating between a female nyala (Tragelaphus angasii) and a male greater kudu (T. strepsiceros). The hybrid was phenotypically nyala and was identified as such based on mitochondrial DNA. Further genetic analysis based on nine microsatellite markers, chromosome number and chromosome morphology however, confirmed its status as an F1 hybrid. Results obtained from a reproductive potential assessment indicated that this animal does not have the potential to breed successfully and can be considered as sterile.

    Recent functional brain connectivity studies have contributed to our understanding of the neurocircuitry supporting pain perception. However, evoked-pain connectivity studies have employed cutaneous and/or brief stimuli, which induce sensations that differ appreciably from the clinical pain experience. Sustained myofascial pain evoked by pressure cuff affords an excellent opportunity to evaluate functional connectivity change to more clinically relevant sustained deep-tissue pain. Connectivity in specific networks known to be modulated by evoked pain (sensorimotor, salience, dorsal attention, frontoparietal control, and default mode networks: SMN, SLN, DAN, FCN, and DMN) was evaluated with functional-connectivity magnetic resonance imaging, both at rest and during a sustained (6-minute) pain state in healthy adults. We found that pain was stable, with no significant changes of subjects' pain ratings over the stimulation period. Sustained pain reduced connectivity between the SMN and the contralateral leg primary sensorimotor (S1/M1) representation. Such SMN-S1/M1 connectivity decreases were also accompanied by and correlated with increased SLN-S1/M1 connectivity, suggesting recruitment of activated S1/M1 from SMN to SLN. Sustained pain also increased DAN connectivity to pain processing regions such as mid-cingulate cortex, posterior insula, and putamen. Moreover, greater connectivity during pain between contralateral S1/M1 and posterior insula, thalamus, putamen, and amygdala was associated with lower cuff pressures needed to reach the targeted pain sensation. These results demonstrate that sustained pain disrupts resting S1/M1 connectivity by shifting it to a network known to process stimulus salience. Furthermore, increased connectivity between S1/M1 and both sensory and affective processing areas may be an important contribution to interindividual differences in pain sensitivity.

    Prominent clinical models of chronic pain propose a fundamental role of classical conditioning in the development of pain-related disability. If classical conditioning is key to this process, then people with chronic pain may show a different response to pain-related conditioned stimuli (CS) than healthy controls. We set out to determine whether this is the case by undertaking a comprehensive and systematic review of the literature. To identify studies comparing classical conditioning between people with chronic pain and healthy controls, the databases MEDLINE, PsychINFO, PsychARTICLES, Scopus, CINAHL, were searched using key words and MESH headings consistent with 'classical conditioning' AND 'pain'. Articles were included when a) pain-free control and chronic pain groups were included, and b) a differential classical conditioning design was used. The systematic search revealed seven studies investigating differences in classical conditioning between people with chronic pain and healthy controls. The included studies involved a total of 129 people with chronic pain (Fibromyalgia syndrome, Spinal pain, Hand pain, Irritable bowel syndrome), and 104 healthy controls. Outcomes included indices of pain-related conditioning such as unconditioned stimulus (US) expectancy and contingency awareness, self-report and physiological measures of pain-related fear, evaluative judgments of conditioned stimulus (CS) pleasantness, and muscular and cortical responses. Due to variability in outcomes, meta-analyses included a maximum of four studies. People with chronic pain tended to show reduced differential learning and flatter generalisation gradients with respect to US-expectancy and fear-potentiated eyeblink startle responses. Some studies demonstrated a propensity for greater muscular responses and perceptions of unpleasantness in response to pain-associated cues, relative to control cues.

    2009-01-01

    Aim: To investigate if pain area in patients with chronic pain could be measured by a computerized assessment on previously marked pain drawings on paper figures and to analyze the further application of the method. Methods: Seventy-two patients (54 women and 18 men) who were admitted to Umeå University Hospital during 2003 for assessment of chronic pain answered a set of questionnaires (pain intensity on the visual analog scale [VAS], disability on the Disability Rating Index [DRI], life satisfaction on the LiSat-11) and filled in pain drawings on paper figures of the human body. The pain drawings were later analyzed by using computerized assessment. Results: Women marked a greater pain area than men, but the difference was not significant (p =0.433). No significant difference was shown for the previous seven days between men and women on the VAS (p =0.914), DRI (p =0.493), or LiSat-11 (p =0.124). A statistically significant correlation was found between pain area and VAS for the previous seven days (r =0.250; p =0.046). Pain area was statistically significantly correlated to the DRI (r =0.336; p =0.014) and close to negatively correlated to the LiSat-11 (r =0.687; p =0.057). Conclusion: This pilot study shows that pain drawing area could be measured by a computerized assessment of pain drawings. The method points to the possibility of relating pain area with other instruments. In the present study, an association between the patients’ pain drawing area and pain intensity and between pain area and level of activity was shown. PMID:19721724

    2004-01-01

    The sacroiliac joint is a source of pain in the lower back and buttocks in approximately 15% of the population. Diagnosing sacroiliac joint-mediated pain is difficult because the presenting complaints are similar to those of other causes of back pain. Patients with sacroiliac joint-mediated pain rarely report pain above L5; most localize their pain to the area around the posterior superior iliac spine. Radiographic and laboratory tests primarily help exclude other sources of low back pain. Magnetic resonance imaging, computed tomography, and bone scans of the sacroiliac joint cannot reliably determine whether the joint is the source of the pain. Controlled analgesic injections of the sacroiliac joint are the most important tool in the diagnosis. Treatment modalities include medications, physical therapy, bracing, manual therapy, injections, radiofrequency denervation, and arthrodesis; however, no published prospective data compare the efficacy of these modalities.

    Objective This study compared the impact of cognitive-behavioral therapy for pain (CBT-P), mindful awareness and acceptance treatment (M), and arthritis education (E) on day-to-day pain- and stress-related changes in cognitions, symptoms, and affect among adults with rheumatoid arthritis (RA). Method 143 RA patients were randomized to one of the three treatment conditions. CBT-P targeted pain coping skills; M targeted awareness and acceptance of current experience to enhance coping with a range of aversive experiences; and E provided information regarding RA pain and its management. At pre- and post-treatment, participants completed 30 consecutive evening diaries assessing that day's pain, fatigue, pain-related catastrophizing and perceived control, morning disability, and serene and anxious affects. Results Multilevel models compared groups in the magnitude of within-person change in daily pain- and stress-reactivity from pre- to post-treatment. M yielded greater reductions than did CBT-P and E in daily pain-related catastrophizing, morning disability, and fatigue, and greater reductions in daily stress-related anxious affect. CBT-P yielded less pronounced declines in daily pain-related perceived control than did M and E. Conclusions For individuals with RA, M produces the broadest improvements in daily pain- and stress-reactivity relative to CBT-P and E. These findings also highlight the utility of a diary-based approach to evaluating the treatment-related changes in responses to daily life. PMID:25365778

    Emotional-affective and cognitive dimensions of pain are less well understood than nociceptive and nocifensive components, but the forebrain is believed to play an important role. Recent evidence suggests subcortical and cortical brain areas outside the traditional pain processing network contribute critically to emotional-affective responses and cognitive deficits related to pain. These brain areas include different nuclei of the amygdala and certain prefrontal cortical areas. Their roles in various aspects of pain will be discussed. Biomarkers of cortical dysfunction are being identified that may evolve into therapeutic targets to modulate pain experience and improve pain-related cognitive impairment. Supporting data from preclinical studies in neuropathic pain models will be presented. Neuroimaging analysis provides evidence for plastic changes in the pain processing brain network. Results of clinical studies in neuropathic pain patients suggest that neuroimaging may help determine mechanisms of altered brain functions in pain as well as monitor the effects of pharmacologic interventions to optimize treatment in individual patients. Recent progress in the analysis of higher brain functions emphasizes the concept of pain as a multidimensional experience and the need for integrative approaches to determine the full spectrum of harmful or protective neurobiological changes in pain.

    Background Chronic pain is common among patients receiving opioid maintenance treatment (OMT) for opioid use disorder. To aid development of treatment recommendations for coexisting pain and opioid use disorder, it is necessary to characterize pain treatment needs and assess whether needs differ as a function of OMT medication. Methods A point-prevalence survey assessing pain and engagement in coping strategies was administered to 179 methadone and buprenorphine-maintained patients. Results Forty-two percent of participants were categorized as having chronic pain. Methadone patients had greater severity of pain relative to buprenorphine patients, though both groups reported high levels of interference with daily activities, and participants with pain attended the emergency room more frequently relative to participants without pain. Only 2 coping strategies were being utilized by more than 50% of participants (over-the-counter medication, prayer). Conclusions Results indicate that pain among OMT patients is common, severe, and of significant impairment. Methadone patients reported greater severity pain, particularly worse pain in the past 24 hours, though interference from pain in daily activities did not vary as a function of OMT. Most participants with pain were utilizing few evidenced-based pain coping strategies. Increasing OMT patient access to additional pain treatment strategies is an opportunity for immediate intervention, and similarities across OMT type suggest interventions do not need to be customized to methadone vs. buprenorphine patients.

    2016-01-01

    Conditioned pain modulation is a powerful analgesic mechanism, occurring when a painful stimulus is inhibited by a second painful stimulus delivered at a different body location. Reduced conditioned pain modulation capacity is associated with the development of some chronic pain conditions and the effectiveness of some analgesic medications. Human lesion studies show that the circuitry responsible for conditioned pain modulation lies within the caudal brainstem, although the precise nuclei in humans remain unknown. We employed brain imaging to determine brainstem sites responsible for conditioned pain modulation in 54 healthy individuals. In all subjects, 8 noxious heat stimuli (test stimuli) were applied to the right side of the mouth and brain activity measured using functional magnetic resonance imaging. This paradigm was then repeated. However, following the fourth noxious stimulus, a separate noxious stimulus, consisting of an intramuscular injection of hypertonic saline into the leg, was delivered (conditioning stimulus). During this test and conditioning stimulus period, 23 subjects displayed conditioned pain modulation analgesia whereas 31 subjects did not. An individual's analgesic ability was not influenced by gender, pain intensity levels of the test or conditioning stimuli or by psychological variables such as pain catastrophizing or fear of pain. Brain images were processed using SPM8 and the brainstem isolated using the SUIT toolbox. Significant increases in signal intensity were determined during each test stimulus and compared between subjects that did and did not display CPM analgesia (p<0.05, small volume correction). The expression of analgesia was associated with reduction in signal intensity increases during each test stimulus in the presence of the conditioning stimulus in three brainstem regions: the caudalis subdivision of the spinal trigeminal nucleus, i.e., the primary synapse, the region of the subnucleus reticularis dorsalis and in the

    This article maps the history of health organisation across Greater Manchester (GM), primarily since the Second World War, to show how against a continuing backdrop of health inequalities, services have been driven (and constrained) by the needs and the politics of each period. Defining ‘success’ as benefits for patients the article identifies examples such as Salford’s mental health services (1950s and 1960s), public health in North Manchester (1970s and 1980s), the creation of centres for diabetes, sickle-cell and thalassaemia (1980s) and the formation of the Joint Health Unit in 2002. What this history shows is that over the period the common factors influencing the ‘success’ of health organisation across GM have been the championing of particular issues by multi-disciplinary groups working across health and social care and stability in structures and personnel.

    Pain assessment is subject to bias due to characteristics of the individual in pain and of the observing person. Few research studies have examined pain assessment biases in an experimental setting. This study employs innovative virtual human technology to achieve greater experimental control. A lens model design was used to capture decision-making policies at the idiographic and nomothetic level. Seventy-five undergraduates viewed virtual humans (VH) that varied in sex, race, age, and pain expression. Participants provided computerized ratings with Visual Analogue Scales on the VH's pain intensity, pain unpleasantness, negative mood, coping, and need for medical treatment. Idiographic analyses revealed that individuals used pain expression most frequently as a significant cue. Nomothetic analyses showed that higher pain expression VH and female VH were viewed as having higher pain intensity, higher pain unpleasantness, greater negative mood, worse coping, and a greater need to seek medical treatment than lower pain expression VH and male VH, respectively. Older VH were viewed as having worse coping and a greater need to seek medical treatment than younger VH. This innovative paradigm involving VH technology and a lens model design was shown to be highly effective and could serve as a model for future studies investigating pain-related decision making in healthcare providers.

    People with chronic pain and comorbid posttraumatic stress disorder (PTSD) report more severe pain and poorer quality of life than those with chronic pain alone. This study evaluated the extent to which associations between PTSD and chronic pain interference and severity are mediated by pain-related coping strategies and depressive symptoms. Veterans with chronic pain were divided into 2 groups, those with (n=65) and those without (n=136) concurrent PTSD. All participants completed measures of pain severity, interference, emotional functioning, and coping strategies. Those with current PTSD reported significantly greater pain severity and pain interference, had more symptoms of depression, and were more likely to meet diagnostic criteria for a current alcohol or substance use disorder (all p-values <.01). Participants with PTSD reported more use of several coping strategies, including guarding, resting, relaxation, exercise/stretching, and coping self-statements. Illness-focused pain coping (i.e., guarding, resting, and asking for assistance) and depressive symptoms jointly mediated the relationship between PTSD and both pain interference (total indirect effect=0.194, p<.001) and pain severity (total indirect effect=0.153, p=.004). Illness-focused pain coping also evidenced specific mediating effects, independent of depression. In summary, specific pain coping strategies and depressive symptoms partially mediated the relationship between PTSD and both pain interference and severity. Future research should examine whether changes in types of coping strategies after targeted treatments predict improvements in pain-related function for chronic pain patients with concurrent PTSD.

Fifty-one professional ballet and contemporary dancers (17 males and 34 females), with the mean age of 25.9 years, completed a general pain questionnaire, the Pain Appraisal Inventory, the Survey of Pain Attitudes Control Subscale, and the Sports Inventory for Pain. Multivariate analyses of variance indicated that both the cognitive appraisal of the pain and pain coping styles did not differ according to the type of pain experienced or the pain severity. However, it was found that dancers with performance pain of either low or high severity were more likely to dance in pain than dancers experiencing injury pain. Multiple regression analyses indicated that the appraisal of pain as threatening was predictive of the use of avoidance and catastrophizing pain coping styles. Overall, results indicated that dancers may not differentiate between performance pain and injury pain, or modify their appraisal and coping strategies according to the characteristics of the pain experienced. The study highlighted an opportunity for increased education for dancers in recognizing the difference between pain considered to be a routine aspect of training and pain which is a signal of serious injury.

    Neuropathic pain (NP) is a debilitating symptom experienced by a number of patients with cancer. We evaluated the validity of ID Pain as a screening tool for NP in breast cancer survivors using the Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) and a reported diagnosis of NP as criterion measures. Two hundred forty breast cancer survivors with a mean age of 58 years (standard deviation=16) participated in this survey. Forty-five percent of the sample reported having pain in the past week. Of those reporting pain, 33% reported that they had been diagnosed by their health care provider with NP, 39% had a positive ID Pain (> or = 2) score, and 19% had a positive S-LANSS score. The most commonly endorsed ID Pain item was "hot/burning" (n=48) followed by feeling "numb" (n=47) and "pins and needles" (n=45). Total ID Pain score was significantly associated with a clinical diagnosis of NP (r=0.41; P<0.001) and the S-LANSS total score (r=0.54; P<0.001). Receiver operating curve analysis demonstrated that ID Pain has a predictive validity of 0.72 and 0.70 for diagnosis of NP as made by clinicians and the S-LANSS, respectively. We also found that an ID Pain score greater than or equal to 2 corresponded with the likelihood of NP in this sample, consistent with the original ID Pain development study. This study provides evidence for ID Pain as a valid screening measure for NP in breast cancer survivors.

    Abstract Background: The number of older jail inmates in poor health is increasing rapidly. Among older adults, pain is common and leads to greater acute care use. In jail, pain management is complicated by concerns about misuse and diversion. A lack of data about the prevalence and management of pain in older jail inmates limits our ability to develop optimal palliative care strategies for this population. Objective: To describe the prevalence of and factors associated with pain and analgesic use in a population of older jail inmates. Design: Cross-sectional study. χ2 tests assessed association between characteristics, pain, and analgesic use. Setting/Subjects: Two hundred ten jail inmates age 55 or older. Measurements: “Severe frequent pain” defined as “severe or very severe” pain experienced “frequently or constantly” using the validated Memorial Symptom Assessment Scale. Medical conditions, substance use, and analgesic treatment determined through self-report and jail medical records. Results: Participants' mean age was 59 years; 69% had multimorbidity; 75% reported any pain; 39% reported severe frequent pain. Report of severe frequent pain was associated with multimorbidity, functional impairment, and pre-jail acute care use (p<0.05), but not with substance use (57% versus 56%, p=0.89). Within a week of their interview, most participants with severe frequent pain had received an analgesic (87%) and many received an opioid (70%). Conclusion: High rates of pain in a rapidly growing population of older jail inmates with multimorbidity and functional impairment suggest that jails are an important site for assessing symptom burden and developing appropriate palliative care interventions.

  3. Occlusion and facial pain.

    PubMed

    Klineberg, I

    1978-02-01

    The role of the occlusion in the aetiology of reflex jaw muscle hyperactivity and myofacial pain is analysed. Neurological mechanisms are proposed to explain how variations in occlusal morphology of sufficient magnitude (segmental influences), and the presence of anxiety states (suprasegmental influences) affect jaw muscle activity and contribute to myofascial pain. Controlled occlusal therapy may alter the segmental neurological control of jaw muscle activity to facilitate resolution of muscle hyperactivity in acute myofascial pain. Chronic myofascial pain dysfunction is not primarily related to occlusal factors and a complex psychophysiological mechanism is involved in this type of pain problem.

    Low back pain is a common condition that is encountered by both primary care physicians as well as various specialists, which include: orthopedic surgeons, physical medicine and rehabilitation specialists, neurologists, rheumatologists, and pain management specialists. Associated muscular pain is very common and often a reactive response from nociception from other structures. Myofascial pain may arise, which is characterized by the presence of myofascial trigger points (MTrPs) that are located in fascia, tendons, and/or muscle. This article reviews the current evidence regarding the pathophysiology, assessment, and recommended treatment options for myofascial low back pain.

    This study aimed to describe the perspectives of surgical patients towards postoperative pain management during their hospital stay. Thirty strategically chosen postoperative inpatients from different surgical wards in a university hospital in Sweden participated. A qualitative, descriptive approach using individual interviews was chosen. These were tape-recorded, transcribed verbatim, and analyzed according to a qualitative content analysis. The patients' descriptions of postoperative pain management indicated that pain was a symptom that was always in focus, either because it was constantly present or because pain could appear abruptly during different activities and movements. Although the focus was on pain and an awareness that it should be relieved or avoided, the solutions were often routine, short-term, and involved the regular intake of drugs, plus additional medication if needed for an acute pain episode. From the patients' descriptions of their experience with postoperative pain management, we distinguished three categories: "patients' pain knowledge", "patients' pain management approaches", and "patients' views of health-care professionals". The findings from this study highlight important aspects of nursing care that should receive greater attention in postoperative pain management. The patients' narratives could be a valuable asset in the quality improvement of postoperative pain management as these narratives highlight episodes difficult to elicit in other ways.

    The demographic factors of sex, age, and race/ethnicity are well recognized as relevant to pain sensitivity and clinical pain expression. Of these, sex differences have been the most frequently studied, and most of the literature describes greater pain sensitivity for women. The other 2 factors have been less frequently evaluated, and current literature is not definitive. Taking advantage of the large Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA) study cohort, we evaluated the association of sex, age, and self-reported race with 34 measures of pressure, mechanical, and thermal pain sensitivity encompassing threshold and suprathreshold perception. Women were significantly more pain-sensitive than men for 29 of 34 measures. Age effects were small, and only significant for 7 of 34 measures, however, the age range was limited (18-44 years of age). Race/ethnicity differences varied across groups and pain assessment type. Non-Hispanic white individuals were less pain-sensitive than African-American (for 21 of 34 measures), Hispanic (19 of 34), and Asian (6 of 34) individuals. No pain threshold measure showed significant racial differences, whereas several suprathreshold pain measures did. This suggests that racial differences are not related to tissue characteristics or inherent nociceptor sensitivity. Rather, the differences observed for suprathreshold pain ratings or tolerance are more likely related to differences in central nociceptive processing, including modulation imposed by cognitive, psychological, and/or affective factors.

    Diagnosing cause of pain in children with severe cognitive impairments is difficult due to their problems with communication. Identification of risk factors for specific pain etiologies might help professionals in this task. The aim of this study was to determine whether child-related characteristics increase risk for specific types of pain. Participants were the caregivers of 41 females and 53 males with moderate to profound mental retardation, who were aged 3 to 18 years 8 months (mean 10:1, SD 4:4) but who communicated at the level of a typical child of 13.8 months (SD 10 months): 44 of the children had cerebral palsy (CP) and 59 a seizure disorder. Caregivers reported the cause of children's episodes of pain for four 1-week periods over 1 year. Logistic regression analyses were used to predict occurrence of specific types of pain using children's demographic, medical, and physical characteristics. Children had 406 episodes of pain due to accident, gastrointestinal conditions, musculoskeletal problems, infection, recurrent conditions, and common childhood causes. Results indicated that a unique set of risk factors predicted each pain type in this sample. Significant risk factors for pain included: lack of visual impairment and leg impairment (accidental pain); seizures, leg impairment, and greater number of medications (non-accidental pain); being male and tube fed (musculoskeletal pain); age <7 years, absence of CP, visual impairment, and less frequent medical monitoring (infection pain); being female and with arm impairment (gastrointestinal pain); and being tube fed and taking fewer medications (common childhood pains). In most cases, models were more specific than sensitive, indicating that the significant predictors are more useful for eliminating potential pain causes. These results suggest that population risk factors may be helpful in structuring diagnostic investigations for individual children with severe cognitive impairments.

    Tobacco addiction and chronic pain represent two highly prevalent and comorbid conditions that engender substantial burdens upon individuals and systems. Although interrelations between pain and smoking have been of clinical and empirical interest for decades, research on the topic of pain, nicotine, and tobacco smoking has increased dramatically over the past five years. We conceptualize the interaction of pain and smoking as a prototypical example of the biopsychosocial model. Accordingly, the current review extrapolated from behavioral, cognitive, affective, biomedical, and social perspectives to propose causal mechanisms that may contribute to the observed comorbidity between these two conditions. Research in the broad area of pain and smoking was first dichotomized into investigations of either "effects of smoking on pain" or "effects of pain on smoking." We then integrated the extant literature to present a reciprocal model of pain and smoking that is hypothesized to interact in the manner of a positive feedback loop, resulting in greater pain, increased smoking, and the maintenance of tobacco addiction. Finally, we proposed directions for future research, and discussed clinical implications for smokers with comorbid pain disorders. We observed modest evidence to support the notions that smoking may be a risk factor in the multifactorial etiology of some chronically painful conditions, and that the experience of pain may come to serve as a potent motivator of smoking. We also found that whereas animal studies yielded consistent support for direct pain-inhibitory effects of nicotine and tobacco smoke, results from human studies were much less consistent. Future research in the emerging area of pain and smoking has the potential to inform theoretical and clinical applications with respect to tobacco smoking, chronic pain, and their comorbid presentation.

  9. Pain in burn patients.

    While severe pain is a constant component of the burn injury, inadequate pain management has been shown to be detrimental to burn patients. Pain-generating mechanisms in burns include nociception, primary and secondary hyperalgesia and neuropathy. The clinical studies of burn pain characteristics reveal very clear-cut differences between continuous pain and pain due to therapeutic procedures which have to be treated separately. Some of the main features of burn pain are: (1) its long-lasting course, often exceeding healing time, (2) the repetition of highly nociceptive procedures which can lead to severe psychological disturbances if pain control is inappropriate. Pharmaco-therapy with opioids is the mainstay for analgesia in burned patients, but non-pharmacological techniques may be useful adjuncts. Routine pain evaluation is mandatory for efficient and safe analgesia. Special attention must be given to pain in burned children which remains too often underestimated and undertreated. More educational efforts from physicians and nursing staff are necessary to improve pain management in burned patients.

    Considerable evidence suggests regular physical activity can reduce chronic pain symptoms. Dysfunction of endogenous facilitatory and inhibitory systems has been implicated in multiple chronic pain conditions. However, few studies have investigated the relationship between levels of physical activity and descending pain modulatory function. Purpose This study’s purpose was to determine whether self-reported levels of physical activity in healthy adults predicted 1) pain sensitivity to heat and cold stimuli, 2) pain facilitatory function as tested by temporal summation of pain (TS), and 3) pain inhibitory function as tested by conditioned pain modulation (CPM) and offset analgesia. Methods Forty-eight healthy adults (age range 18–76) completed the International Physical Activity Questionnaire (IPAQ) and the following pain tests: heat pain thresholds (HPT), heat pain suprathresholds, cold pressor pain (CPP), temporal summation of heat pain, conditioned pain modulation, and offset analgesia. The IPAQ measured levels of walking, moderate, vigorous and total physical activity over the past seven days. Hierarchical linear regressions were conducted to determine the relationship between each pain test and self-reported levels of physical activity, while controlling for age, sex and psychological variables. Results Self-reported total and vigorous physical activity predicted TS and CPM (p’s <.05). Individuals who self-reported more vigorous and total physical activity exhibited reduced temporal summation of pain and greater CPM. The IPAQ measures did not predict any of the other pain measures. Conclusion Thus, these results suggest that healthy older and younger adults who self-report greater levels of vigorous and total physical activity exhibit enhanced descending pain modulatory function. Improved descending pain modulation may be a mechanism through which exercise reduces or prevents chronic pain symptoms. PMID:23899890

    Ibn Sina (Latin name - Avicenna, 980-1037) is a famous Muslim physician who wrote The Canon of Medicine. Pain-related writings within The Canon were identified and analysed and compared to Galen and Modern Pain Theory. We found evidence in The Canon that Avicenna challenged Galen's concept of pain. Galen insisted that injuries (breach of continuity) were the only cause of pain. In contrast, Avicenna suggested that the true cause of pain was a change of the physical condition (temperament change) of the organ whether there was an injury present or not. Avicenna extended Galen's descriptions of 4 to 15 types of pain and used a terminology that is remarkably similar to that used in the McGill Pain Questionnaire.

    Pain in infancy and childhood is extremely common. Sources of pain include illness, injury, and medical and dental procedures. Over the past two decades, tremendous progress has been made in the assessment, prevention and treatment of pain. It is important for the paediatric health care provider to be aware of the implications and consequences of pain in childhood. A multitude of interventions are available to reduce or alleviate pain in children of all ages, including neonates. These include behavioural and psychological methods, as well as a host of pharmacological preparations, which are safe and effective when used as indicated. Many complementary and alternative treatments appear to be promising in treating and relieving pain, although further research is required. The present article reviews the most common sources of pain in childhood and infancy, as well as current treatment strategies and options. PMID:19030348

  13. Pain emotion and homeostasis.

    PubMed

    Panerai, Alberto E

    2011-05-01

    Pain has always been considered as part of a defensive strategy, whose specific role is to signal an immediate, active danger. This definition partially fits acute pain, but certainly not chronic pain, that is maintained also in the absence of an active noxa or danger and that nowadays is considered a disease by itself. Moreover, acute pain is not only an automatic alerting system, but its severity and characteristics can change depending on the surrounding environment. The affective, emotional components of pain have been and are the object of extensive attention and research by psychologists, philosophers, physiologists and also pharmacologists. Pain itself can be considered to share the same genesis as emotions and as a specific emotion in contributing to the maintenance of the homeostasis of each unique subject. Interestingly, this role of pain reaches its maximal development in the human; some even argue that it is specific for the human primate.

    Arrays of multiple, nominally identical sensors with sensor-output-processing electronic hardware and software are being developed in order to obtain accuracy, reliability, and lifetime greater than those of single sensors. The conceptual basis of this development lies in the statistical behavior of multiple sensors and a multisensor-array (MSA) algorithm that exploits that behavior. In addition, advances in microelectromechanical systems (MEMS) and integrated circuits are exploited. A typical sensor unit according to this concept includes multiple MEMS sensors and sensor-readout circuitry fabricated together on a single chip and packaged compactly with a microprocessor that performs several functions, including execution of the MSA algorithm. In the MSA algorithm, the readings from all the sensors in an array at a given instant of time are compared and the reliability of each sensor is quantified. This comparison of readings and quantification of reliabilities involves the calculation of the ratio between every sensor reading and every other sensor reading, plus calculation of the sum of all such ratios. Then one output reading for the given instant of time is computed as a weighted average of the readings of all the sensors. In this computation, the weight for each sensor is the aforementioned value used to quantify its reliability. In an optional variant of the MSA algorithm that can be implemented easily, a running sum of the reliability value for each sensor at previous time steps as well as at the present time step is used as the weight of the sensor in calculating the weighted average at the present time step. In this variant, the weight of a sensor that continually fails gradually decreases, so that eventually, its influence over the output reading becomes minimal: In effect, the sensor system "learns" which sensors to trust and which not to trust. The MSA algorithm incorporates a criterion for deciding whether there remain enough sensor readings that

    [Purpose] The aim of this study was to ascertain the prevalence of chronic widespread musculoskeletal pain in patients with obstructive sleep apnea syndrome and to assess the relationship between sleep disorder and pain, quality of life, and disability. [Subjects and Methods] Seventy-four patients were included in the study and classified as having mild, moderate, or severe obstructive sleep apnea. Chronic widespread pain, quality of life, and disability were evaluated. [Results] Forty-one patients (55.4%) had chronic widespread pain. Female patients had a higher incidence of chronic pain, and female patients with chronic pain had higher body mass indexes, pain levels, and disability scores than did male patients. Physical component scores of female patients with chronic pain were lower than those of male patients. No correlation was observed between the degree of sleep disorder and severity of pain, pain duration, disability, or quality of life in obstructive sleep apnea patients with pain. [Conclusion] This study showed a 55.4% prevalence of chronic widespread pain in patients with obstructive sleep apnea and a greater risk of chronic pain in female than in male patients. Female patients with obstructive sleep apnea and chronic pain have higher pain and disability levels and a lower quality of life. PMID:26504332

    Objective The objective of this study was to investigate the existence of an equine pain face and to describe this in detail. Study design Semi-randomized, controlled, crossover trial. Animals Six adult horses. Methods Pain was induced with two noxious stimuli, a tourniquet on the antebrachium and topical application of capsaicin. All horses participated in two control trials and received both noxious stimuli twice, once with and once without an observer present. During all sessions their pain state was scored. The horses were filmed and the close-up video recordings of the faces were analysed for alterations in behaviour and facial expressions. Still images from the trials were evaluated for the presence of each of the specific pain face features identified from the video analysis. Results Both noxious challenges were effective in producing a pain response resulting in significantly increased pain scores. Alterations in facial expressions were observed in all horses during all noxious stimulations. The number of pain face features present on the still images from the noxious challenges were significantly higher than for the control trial (p = 0.0001). Facial expressions representative for control and pain trials were condensed into explanatory illustrations. During pain sessions with an observer present, the horses increased their contact-seeking behavior. Conclusions and clinical relevance An equine pain face comprising ‘low’ and/or ‘asymmetrical’ ears, an angled appearance of the eyes, a withdrawn and/or tense stare, mediolaterally dilated nostrils and tension of the lips, chin and certain facial muscles can be recognized in horses during induced acute pain. This description of an equine pain face may be useful for improving tools for pain recognition in horses with mild to moderate pain. PMID:25082060

    The Greater Vancouver Regional District commissioned an 18-month planning and predesign study to define the components in a comprehensive water and predesign study to define the components in a comprehensive water quality improvement plan for its 2,500-ML/d (660-mgd) system. The study included three primary tasks: (1) predesign of disinfection and corrosion control facilities, (2) a 12-month pilot testing program using parallel pilot plants at the Seymour and Capilano water supply reservoirs, and (3) planning for future filtration plants. The results of the study identified chlorine, ammonia, sulfur dioxide, soda ash, and carbon dioxide in a two-stage treatment approach as the recommended disinfection and corrosion control scheme for the low-pH, low-alkalinity water supplies. The pilot-plant studies confirmed that direct filtration using deep-bed monomedium filters operating at a loading rate of 22.5 m/h provided excellent treatment performance and productivity over a wide range of raw-water quality. Ozonation was studied extensively and found not to be beneficial in the overall treatment performance. The phased improvement plan for the disinfection, corrosion control, and filtration facilities has an estimated capital cost of about Can$459 million.

    The Greater Green River Basin (GGRB) of Wyoming has produced abundant oil and gas out of multiple reservoirs for over 60 years, and large quantities of gas remain untapped in tight gas sandstone reservoirs. Even though GGRB production has been established in formations from the Paleozoic to the Tertiary, recent activity has focused on several Cretaceous reservoirs. Two of these formations, the Ahnond and the Frontier Formations, have been classified as tight sands and are prolific producers in the GGRB. The formations typically naturally fractured and have been exploited using conventional well technology. In most cases, hydraulic fracture treatments must be performed when completing these wells to to increase gas production rates to economic levels. The objectives of the GGRB production improvement project were to apply the concept of horizontal and directional drilling to the Second Frontier Formation on the western flank of the Rock Springs Uplift and to compare production improvements by drilling, completing, and testing vertical, horizontal and directionally-drilled wellbores at a common site.

    The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA) receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, potentially infested places were entomologically evaluated. T. infestans was only detected in a hen building for egg production, which housed approximately 6,000 birds. A total of 2,930 insects were collected. Density was about 9 triatomines/m(2). The proportions of fifth instar nymphs and adults were significantly higher than those of the other stages (p<0.001). The number of triatomines collected largely exceeded the highest domestic infestation found in one house from rural endemic areas of Argentina. Though triatomines were negative for Trypanosoma cruzi, they could acquire the parasite by coming in contact with infected people living in GBA. Besides, the numerous and widely distributed places housing hens and chickens, would favor the settlement of the vector. Together, both facts may constitute a risk of parasitic vectorial transmission. It is recommended to intensify systematic activities of vector search and case detection in GBA.

    Manual therapy is often used with exercise to treat neck pain. This cervical overview group systematic review update assesses if manual therapy, including manipulation or mobilisation, combined with exercise improves pain, function/disability, quality of life, global perceived effect, and patient satisfaction for adults with neck pain with or without cervicogenic headache or radiculopathy. Computerized searches were performed to July 2009. Two or more authors independently selected studies, abstracted data, and assessed methodological quality. Pooled relative risk (pRR) and standardized mean differences (pSMD) were calculated. Of 17 randomized controlled trials included, 29% had a low risk of bias. Low quality evidence suggests clinically important long-term improvements in pain (pSMD-0.87(95% CI:-1.69,-0.06)), function/disability, and global perceived effect when manual therapy and exercise are compared to no treatment. High quality evidence suggests greater short-term pain relief [pSMD-0.50(95% CI:-0.76,-0.24)] than exercise alone, but no long-term differences across multiple outcomes for (sub)acute/chronic neck pain with or without cervicogenic headache. Moderate quality evidence supports this treatment combination for pain reduction and improved quality of life over manual therapy alone for chronic neck pain; and suggests greater short-term pain reduction when compared to traditional care for acute whiplash. Evidence regarding radiculopathy was sparse. Specific research recommendations are made.

    Hospitalized children frequently receive inadequate pain assessment and management despite substantial evidence to support effective pediatric pain practices. The objective of this study was to determine the effect of a multidimensional knowledge translation intervention, Evidence-based Practice for Improving Quality (EPIQ), on procedural pain practices and clinical outcomes for children hospitalized in medical, surgical and critical care units. A prospective cohort study compared 16 interventions using EPIQ and 16 standard care (SC) units in 8 Canadian pediatric hospitals. Chart reviews at baseline (time 1) and intervention completion (time 2) determined the nature and frequency of painful procedures and of pain assessment and pain management practices. Trained pain experts evaluated pain intensity 6 months post-intervention (time 3) during routine, scheduled painful procedures. Generalized estimating equation models compared changes in outcomes between EPIQ and SC units over time. EPIQ units used significantly more validated pain assessment tools (P<0.001) and had a greater proportion of patients who received analgesics (P=0.03) and physical pain management strategies (P=0.02). Mean pain intensity scores were significantly lower in the EPIQ group (P=0.03). Comparisons of moderate (4-6/10) and severe (7-10/10) pain, controlling for child and unit level factors, indicated that the odds of having severe pain were 51% less for children in the EPIQ group (adjusted OR: 0.49, 95% CI: 0.26-0.83; P=0.009). EPIQ was effective in improving practice and clinical outcomes for hospitalized children. Additional exploration of the influence of contextual factors on research use in hospital settings is required to explain the variability in pain processes and clinical outcomes.

    The present review summarizes the current state of knowledge about the genetics of pain-related phenomena and illustrates the scope and power of genetic approaches to the study of pain. We focus on work performed in our laboratories in Jastrzebiec, Poland; Portland, OR; and Los Angeles, which we feel demonstrates the continuing usefulness of classical genetic approaches, especially when used in combination with newly available molecular genetic techniques.

Decreased pain sensitivity seems to be an endophenotype of schizophrenia spectrum disorders. How this alteration links to other dimensions of schizophrenia and physical comorbidity-related help-seeking behaviour/morbidity/mortality requires further study.

    Pain is a ubiquitous yet highly variable experience. The psychophysiological and genetic factors responsible for this variability remain unresolved. We hypothesised the existence of distinct human pain clusters (PCs) composed of distinct psychophysiological and genetic profiles coupled with differences in the perception and the brain processing of pain. We studied 120 healthy subjects in whom the baseline personality and anxiety traits and the serotonin transporter-linked polymorphic region (5-HTTLPR) genotype were measured. Real-time autonomic nervous system parameters and serum cortisol were measured at baseline and after standardised visceral and somatic pain stimuli. Brain processing reactions to visceral pain were studied in 29 subjects using functional magnetic resonance imaging (fMRI). The reproducibility of the psychophysiological responses to pain was assessed at year. In group analysis, visceral and somatic pain caused an expected increase in sympathetic and cortisol responses and activated the pain matrix according to fMRI studies. However, using cluster analysis, we found 2 reproducible PCs: at baseline, PC1 had higher neuroticism/anxiety scores (P ≤ 0.01); greater sympathetic tone (P<0.05); and higher cortisol levels (P ≤ 0.001). During pain, less stimulus was tolerated (P ≤ 0.01), and there was an increase in parasympathetic tone (P ≤ 0.05). The 5-HTTLPR short allele was over-represented (P ≤ 0.005). PC2 had the converse profile at baseline and during pain. Brain activity differed (P ≤ 0.001); greater activity occurred in the left frontal cortex in PC1, whereas PC2 showed greater activity in the right medial/frontal cortex and right anterior insula. In health, 2 distinct reproducible PCs exist in humans. In the future, PC characterization may help to identify subjects at risk for developing chronic pain and may reduce variability in brain imaging studies.

    Effective pain management is a desirable standard of care for preterm and term newborns and may potentially improve their clinical and neurodevelopmental outcomes. Neonatal pain should be assessed routinely using context-specific, validated and objective pain methods, despite the limitations of currently available tools. Reducing invasive procedures, and using pharmacological, behavioral or environmental measures can be used to manage neonatal pain. Non-pharmacologic approaches include kangaroo care, facilitated tucking, non-nutritive sucking, sucrose and other sweeteners, massage and acupuncture therapy. They are used for procedures causing acute, transient, or mild pain, or as adjunctive therapy for moderate or severe pain. Local and topical anesthetics can reduce the acute pain caused by skin-breaking or mucosa-injuring procedures. Opioids form the mainstay for treatment of severe pain; morphine and fentanyl are the most commonly used drugs, although other opioids are also available. Non-opioid drugs include various sedatives and anesthetic agents, mostly used as adjunctive therapy in ventilated neonates. Acetaminophen, ibuprofen and other drugs are used for neonates, although their efficacy and safety remains unproven. Approaches for implementing an effective pain management program in the Neonatal ICU are summarized, together with practical protocols for procedural, postoperative, and mechanical ventilation-associated neonatal pain and stress.

    Pain has been reported to be a common problem in the general population and end-stage renal disease (ESRD) patients. Although similar data for pre-ESRD patients are lacking, we recently reported that the prevalence of pain is also very high (>70%) among pre-ESRD patients at a Los Angeles County tertiary referral centre. The high prevalence of pain in the CKD population is particularly concerning because pain has been shown to be associated with poor quality of life. Of greater concern, poor quality of life, at least in dialysis patients, has been shown to be associated with poor survival. We herein discuss the pathophysiology of common pain conditions, review a commonly accepted approach to the management of pain in the general population, and discuss analgesic-induced renal complications and therapeutic issues specific for patients with reduced renal function.

    Objective As smoking impacts physiological pathways in the central nervous system, it is important to consider the association between smoking and fibromyalgia, a pain condition caused predominantly by central nervous system dysfunction. The objectives were to assess the prevalence of current smoking among treatment-seeking chronic pain patients with (FM+) and without (FM−) a fibromyalgia-like phenotype; test the individual and combined influence of smoking and fibromyalgia on pain severity and interference; and examine depression as a mediator of these processes. Methods Questionnaire data from 1566 patients evaluated for a range of conditions at an outpatient pain clinic were used. The 2011 Survey Criteria for Fibromyalgia were used to assess the presence of symptoms associated with fibromyalgia. Results Current smoking was reported by 38.7% of FM+ patients compared to 24.7% of FM− patients. FM+ smokers reported higher pain and greater interference compared to FM+ nonsmokers, FM− smokers, and FM− nonsmokers. There was no interaction between smoking and fibromyalgia. Significant indirect effects of fibromyalgia and smoking via greater depression were observed for pain severity and interference. Conclusions Current smoking and positive fibromyalgia status were associated with greater pain and impairment among chronic pain patients, possibly as a function of depression. Although FM+ smokers report the most negative clinical symptomatology (i.e., high pain, greater interference) smoking does not appear to have a unique association with pain or functioning in FM+ patients, rather the effect is additive. The 38.7% smoking rate in FM+ patients is high, suggesting FM+ smokers present a significant clinical challenge. PMID:25801019

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

    2012-01-01

    Introduction On 6 April 2009, at 03:32 local time, an Mw 6.3 earthquake hit the Abruzzi region of central Italy causing widespread damage in the City of L Aquila and its nearby villages. The earthquake caused 308 casualties and over 1,500 injuries, displaced more than 25,000 people and induced significant damage to more than 10,000 buildings in the L'Aquila region. Objectives This observational retrospective study evaluated the prevalence and drug treatment of pain in the five weeks following the L'Aquila earthquake (April 6, 2009). Methods 958 triage documents were analysed for patients pain severity, pain type, and treatment efficacy. Results A third of pain patients reported pain with a prevalence of 34.6%. More than half of pain patients reported severe pain (58.8%). Analgesic agents were limited to available drugs: anti-inflammatory agents, paracetamol, and weak opioids. Reduction in verbal numerical pain scores within the first 24 hours after treatment was achieved with the medications at hand. Pain prevalence and characterization exhibited a biphasic pattern with acute pain syndromes owing to trauma occurring in the first 15 days after the earthquake; traumatic pain then decreased and re-surged at around week five, owing to rebuilding efforts. In the second through fourth week, reports of pain occurred mainly owing to relapses of chronic conditions. Conclusions This study indicates that pain is prevalent during natural disasters, may exhibit a discernible pattern over the weeks following the event, and current drug treatments in this region may be adequate for emergency situations.

  11. Basic science of pain.

    PubMed

    DeLeo, Joyce A

    2006-04-01

    The origin of the theory that the transmission of pain is through a single channel from the skin to the brain can be traced to the philosopher and scientist René Descartes. This simplified scheme of the reflex was the beginning of the development of the modern doctrine of reflexes. Unfortunately, Descartes' reflex theory directed both the study and treatment of pain for more than 330 years. It is still described in physiology and neuroscience textbooks as fact rather than theory. The gate control theory proposed by Melzack and Wall in 1965 rejuvenated the field of pain study and led to further investigation into the phenomena of spinal sensitization and central nervous system plasticity, which are the potential pathophysiologic correlates of chronic pain. The processing of pain takes place in an integrated matrix throughout the neuroaxis and occurs on at least three levels-at peripheral, spinal, and supraspinal sites. Basic strategies of pain control monopolize on this concept of integration by attenuation or blockade of pain through intervention at the periphery, by activation of inhibitory processes that gate pain at the spinal cord and brain, and by interference with the perception of pain. This article discusses each level of pain modulation and reviews the mechanisms of action of opioids and potential new analgesics. A brief description of animal models frames a discussion about recent advances regarding the role of glial cells and central nervous system neuroimmune activation and innate immunity in the etiology of chronic pain states. Future investigation into the discovery and development of novel, nonopioid drug therapy may provide needed options for the millions of patients who suffer from chronic pain syndromes, including syndromes in which the pain originates from peripheral nerve, nerve root, spinal cord, bone, muscle, and disc.

  12. Diagnosis of heel pain.

    Heel pain is a common presenting symptom in ambulatory clinics. There are many causes, but a mechanical etiology is most common. Location of pain can be a guide to the proper diagnosis. The most common diagnosis is plantar fasciitis, a condition that leads to medial plantar heel pain, especially with the first weight-bearing steps in the morning and after long periods of rest. Other causes of plantar heel pain include calcaneal stress fracture (progressively worsening pain following an increase in activity level or change to a harder walking surface), nerve entrapment (pain accompanied by burning, tingling, or numbness), heel pad syndrome (deep, bruise-like pain in the middle of the heel), neuromas, and plantar warts. Achilles tendinopathy is a common condition that causes posterior heel pain. Other tendinopathies demonstrate pain localized to the insertion site of the affected tendon. Posterior heel pain can also be attributed to a Haglund deformity, a prominence of the calcaneus that may cause bursa inflammation between the calcaneus and Achilles tendon, or to Sever disease, a calcaneal apophysitis in children. Medial midfoot heel pain, particularly with continued weight bearing, may be due to tarsal tunnel syndrome, which is caused by compression of the posterior tibial nerve as it courses through the flexor retinaculum, medial calcaneus, posterior talus, and medial malleolus. Sinus tarsi syndrome occurs in the space between the calcaneus, talus, and talocalcaneonavicular and subtalar joints. The syndrome manifests as lateral midfoot heel pain. Differentiating among causes of heel pain can be accomplished through a patient history and physical examination, with appropriate imaging studies, if indicated.

    Objectives A significant proportion of children with functional abdominal pain develop chronic pain. Identifying clinical characteristics predicting pain persistence is important in targeting interventions. We examined whether child anxiety and/or pain-stooling relations were related to maintenance of abdominal pain frequency and compared the predictive value of three methods for assessing pain-stooling relations (i.e., diary, parent report, child report). Methods Seventy-six children (7–10-years-old at baseline) who presented for medical treatment of functional abdominal pain were followed up 18–24 months later. Baseline anxiety and abdominal pain-stooling relations based on pain and stooling diaries and child- and parent-questionnaires were examined in relationship to the persistence of abdominal pain frequency. Results Children’s baseline anxiety was not related to persistence of pain frequency. However, children who displayed irritable bowel syndrome (IBS) symptoms at baseline maintained pain frequency at follow-up, whereas in children in whom there was no relationship between pain and stooling, pain frequency decreased. Pain and stool diaries and parent report of pain-stooling relations were predictive of pain persistence but child-report questionnaires were not. Conclusions The presence of IBS symptoms in school age children with functional abdominal pain appears to predict persistence of abdominal pain over time, while anxiety does not. Prospective pain and stooling diaries and parent report of IBS symptoms were predictors of pain maintenance, but child report of symptoms was not. PMID:26301615

    Background Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a condition characterized by pelvic pain and urinary symptoms. Some IC/BPS patients have pain confined to the pelvic region, while others suffer widespread pain. Inflammatory processes have previously been linked to pelvic pain in IC/BPS, but their association with widespread pain in IC/BPS has not been characterized. Methods Sixty-six women meeting criteria for IC/BPS completed self-report measures of pain as part of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP), collected 3 days of saliva for cortisol assays, and provided blood samples. Peripheral blood mononuclear cells (PBMCs) were stimulated with Toll-Like Receptor (TLR) 2 and 4 agonists and cytokines were measured in supernatant; IL-6 was also measured in plasma. Associations between inflammatory variables and the likelihood of endorsing extra-pelvic pain, or the presence of a comorbid syndrome, were tested by logistic regression and General Linear Models, respectively. A subset of patients (n=32) completed Quantitative Sensory Testing. Results A one standard deviation increase in TLR-4 inflammatory response was associated with a 1.59 greater likelihood of endorsing extra-pelvic pain (p = .019). Participants with comorbid syndromes also had higher inflammatory responses to TLR-4 stimulation in PBMCs (p = .016). Lower pressure pain thresholds were marginally associated with higher TLR-4 inflammatory responses (p = .062), and significantly associated with higher IL-6 in plasma (p = .031). Conclusions TLR-4 inflammatory responses in PBMCs are a marker of widespread pain in IC/BPS, and should be explored in other conditions characterized by medically unexplained pain. PMID:25771510

    Objective: To assess the relationship between shoulder mobility and strength and the presence of pain among baseball players. Methods: Between April and July 2009, 55 baseball players were assessed by the Shoulder and Elbow Group of the School of Medical Sciences, Santa Casa de Misericórdia, São Paulo. They were all males, aged between 15 and 33 years (mean of 21); they attended an average of three training sessions per week and had been doing this sport for a mean of 10 years. Results: 14 of the 55 players evaluated were pitchers, and 20 reported pain during the pitching motion. The mean values for lateral and medial rotation and range of motion (ROM) in the dominant shoulder were, respectively, 110 °, 61 ° and 171 °, with a statistically significant difference in relation to the non-dominant limb. Pitchers had greater gains in lateral rotation and deficits in medial rotation than did non-pitchers. Pain presented a statistically significant correlation with diminished ROM, greater length of time playing the sport and situations of “shoulder at risk”. Conclusions: Statistically significant differences in dominant shoulder mobility were found, with increased lateral rotation, diminished medial rotation and smaller ROM, in relation to the contralateral limb. There was a statistically significant relationship between the pitcher's position and greater gain in lateral rotation and diminished medial rotation. There were statistically significant correlations between pain and diminished ROM, greater length of time playing the sport and situations of “shoulder at risk”. There was a statistical tendency suggesting that players with diminished medial rotation of the dominant shoulder presented a relationship with pain. PMID:27028320

    Functional neuroimaging has fundamentally changed our knowledge about the cerebral representation of pain. For the first time it has been possible to delineate the functional anatomy of different aspects of pain in the medial and lateral pain systems in the brain. The rapid developments in imaging methods over the past years have led to a consensus in the description of the central pain responses between different studies and also to a definition of a central pain matrix with specialized subfunctions in man. In the near future we will see studies where a systems perspective allows for a better understanding of the regulatory mechanisms in the higher-order frontal and parietal cortices. Also, pending the development of experimental paradigms, the functional anatomy of the emotional aspects of pain will become better known. PMID:10466155

    2009-10-01

    Confusion between radicular and nerve trunk syndrome is not rare. With sciatic pain, any nerve trunk pain or an atypical nerve course should suggest nerve trunk pain of the sciatic nerve in the buttocks. The usual reflex with sciatic pain is vertebral-radicular conflict. The absence of spinal symptoms and the beginning of pain in the buttocks and not in the lumbar region should reorient the etiologic search. Once a tumor of the nerve trunk has been ruled out (rarely responsible for pain other than that caused by tumor pressure), a myofascial syndrome should be explored searching for clinical, electrophysiological, and radiological evidence of compression of the sciatic trunk by the piriform muscle but also the obturator internus muscle. Hamstring syndrome may be confused with this syndrome. Treatment is first and foremost physical therapy. Failures can be treated with classical CT-guided infiltrations with botulinum toxin. Surgery should only be entertained when all these solutions have failed.

    2016-01-01

    Background painDETECT is a screening measure for neuropathic pain. The nine-item version consists of seven sensory items (burning, tingling/prickling, light touching, sudden pain attacks/electric shock-type pain, cold/heat, numbness, and slight pressure), a pain course pattern item, and a pain radiation item. The seven-item version consists only of the sensory items. Total scores of both versions discriminate average pain-severity levels (mild, moderate, and severe), but their ability to discriminate individual item severity has not been evaluated. Methods Data were from a cross-sectional, observational study of six neuropathic pain conditions (N=624). Average pain severity was evaluated using the Brief Pain Inventory-Short Form, with severity levels defined using established cut points for distinguishing mild, moderate, and severe pain. The Wilcoxon rank sum test was followed by ridit analysis to represent the probability that a randomly selected subject from one average pain-severity level had a more favorable outcome on the specific painDETECT item relative to a randomly selected subject from a comparator severity level. Results A probability >50% for a better outcome (less severe pain) was significantly observed for each pain symptom item. The lowest probability was 56.3% (on numbness for mild vs moderate pain) and highest probability was 76.4% (on cold/heat for mild vs severe pain). The pain radiation item was significant (P<0.05) and consistent with pain symptoms, as well as with total scores for both painDETECT versions; only the pain course item did not differ. Conclusion painDETECT differentiates severity such that the ability to discriminate average pain also distinguishes individual pain item severity in an interpretable manner. Pain-severity levels can serve as proxies to determine treatment effects, thus indicating probabilities for more favorable outcomes on pain symptoms. PMID:27555789

    2014-01-01

    Musculoskeletal pain conditions, such as fibromyalgia and low back pain, tend to coexist in affected individuals and are characterized by a report of pain greater than expected based on the results of a standard physical evaluation. The pathophysiology of these conditions is largely unknown, we lack biological markers for accurate diagnosis, and conventional therapeutics have limited effectiveness. Growing evidence suggests that chronic pain conditions are associated with both physical and psychological triggers, which initiate pain amplification and psychological distress; thus, susceptibility is dictated by complex interactions between genetic and environmental factors. Herein, we review phenotypic and genetic markers of common musculoskeletal pain conditions, selected based on their association with musculoskeletal pain in previous research. The phenotypic markers of greatest interest include measures of pain amplification and ‘psychological’ measures (such as emotional distress, somatic awareness, psychosocial stress and catastrophizing). Genetic polymorphisms reproducibly linked with musculoskeletal pain are found in genes contributing to serotonergic and adrenergic pathways. Elucidation of the biological mechanisms by which these markers contribute to the perception of pain in these patients will enable the development of novel effective drugs and methodologies that permit better diagnoses and approaches to personalized medicine.

    2015-01-01

    Facial mimicry has been suggested to be a behavioral index for emotional empathy. The present study is the first to investigate the link between facial muscle activity and empathy for pain by facial electromyographic (EMG) recording while observers watched videos depicting real-life painful events. Three types of visual stimulus were used: an intact painful scene and arm-only (needle injection) and face only (painful expression) scenes. Enhanced EMG activity of the corrugator supercilii (CS) and zygomaticus major (ZM) muscles was found when observers viewed others in pain, supporting a unique pain expression that is distinct from the expression of basic emotions. In the intact video stimulus condition, CS activity was correlated positively with the empathic concern score and ZM activity, suggesting facial mimicry mediated empathy for pain. Cluster analysis of facial EMG responses revealed markedly different patterns among stimulus types, including response category, ratio, and temporal dynamics, indicating greater ecological validity of the intact scene in eliciting pain empathy as compared with partial scenes. This study is the first to quantitatively describe pain empathy in terms of facial EMG data. It may provide important evidence for facial mimicry as a behavioral indicator of pain empathy.

    2015-01-01

    Low-back pain is one of the most common painful conditions experienced by humans throughout their life. Some occupational risk factors (namely, heavy manual material handling) may also contribute to the development of low-back pain: due to the high prevalence of both low-back pain and manual material handling in the adult working population, it has been estimated that low-back pain is probably the most common occupational disorder worldwide. Lifetime prevalence of low-back pain has been reported to be as high as 84%, depending on the case definition used, and no age group is spared, even children. Although low-back pain is not a lethal condition, it was estimated at the third rank among all diseases by disability-adjusted life-years in 2010 in the USA, after ischemic heart disease and chronic obstructive pulmonary disease, and at the first rank by years lived with disability. It also ranked high (13th) globally for the same year, in disability-adjusted life-years. Low-back pain is currently classified as nonspecific/specific as to putative cause and as acute (lasting less than 6 weeks), subacute (6-12 weeks), or chronic (more than 12 weeks) according to duration of symptoms. The distinction between nonspecific/specific and acute/subacute/chronic low-back pain is useful not only for epidemiologic studies, but also (mainly) for choosing the appropriate strategy for the diagnosis and treatment of the disorder. Workplace risk factors for low-back pain include manual lifting and whole-body vibration exposure. This chapter will provide an overview of modern concepts of low-back pain (in general) and will then outline some distinctive features of work-related low-back pain.

    Background Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled “Orofacial Pain and Cancer” (Dolor Orofacial y Cancer) given at the VI Simposio International “Advances in Oral Cancer” on the 22 July, 2016 in Donostia. Material and Methods We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. Results There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. Conclusions The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years. Key words:Pain, orofacial, facial, cancer. PMID:27694791

    Chronic pain is prevalent in the western world; however fear of pain often has a greater impact than the degree of initial injury. The aim of this study was to explore the relationship between knowledge of the neurophysiology of pain and fear avoidance in individuals diagnosed with chronic pain. Twenty-nine people with chronic musculoskeletal pain were recruited and completed questionnaires to determine their understanding of pain neurophysiology and the degree of their fear avoidance beliefs. There was an inverse relationship between knowledge of pain neurophysiology and the level of fear avoidance. Patients with higher pain knowledge reported less fear avoidance and lower perceived disability due to pain. There was no relationship with the educational level or compensable status for either variable. The findings suggest that fear avoidance is positively influenced by neurophysiology of pain education, so that a higher level of pain knowledge is associated with less activity-related fear. The clinical implication is that reducing fear avoidance/kinesiophobia using neurophysiology of pain education in people with chronic pain may provide an effective strategy to help manage fear avoidance and related disability in the chronic pain population in order to improve treatment outcomes.

    In this study we examined pain and disability in 115 community-dwelling, urban, older adults (mean age = 74 years; 52% Black, 48% White). Participants completed a survey of pain (pain presence, intensity, locations, and duration) and disability (Sickness Impact Profile). Sixty percent of the sample reported pain; Black and White adults did not differ on any pain variable. In structural equation models controlling for socioeconomic factors and health, pain did not mediate the relationship between race and disability. Race moderated the pain-disability relationship; pain was more associated with disability among Whites than Blacks.

    Boney metastasis may lead to terrible suffering from debilitating pain. The most likely malignancies that spread to bone are prostate, breast, and lung. Painful osseous metastases are typically associated with multiple episodes of breakthrough pain which may occur with activities of daily living, weight bearing, lifting, coughing, and sneezing. Almost half of these breakthrough pain episodes are rapid in onset and short in duration and 44% of episodes are unpredictable. Treatment strategies include: analgesic approaches with "triple opioid therapy", bisphosphonates, chemotherapeutic agents, hormonal therapy, interventional and surgical approaches, steroids, radiation (external beam radiation, radiopharmaceuticals), ablative techniques (radiofrequency ablation, cryoablation), and intrathecal analgesics.

    The frequency and nature of exertion pains of the leg in athletes were studied in 2,750 cases of overuse injuries treated at the Sports Clinic of the Deaconess Institute of Oulu, Finland, during the years 1972-1977. 465 cases of exertion pain (18%) were located in the shin. The medial tibial syndrome was the most common overuse injury among these athletes, comprising 9.5% of all exertion injuries and 60% of the leg exertion pains. Together with stress fracture of the tibia, the second most common exertion pain of the leg, it accounted for 75% of the total leg pains. There are certain difficulties in differentiating between the medial tibial syndrome and stress fracture of the tibia. They both occur at the same site with similar symptoms. Radiological examination and isotope scanning are needed. The medial tibial syndrome is an overuse injury at the medial tibial border caused by running exercises. The pain is elicited by exertional ischaemia. The pathogenesis is explained by increased pressure in the fascial compartment of the deep flexor muscles due to prolonged exercise. Similar chronic ischaemic pains from exercise are also found in other fascial compartments of the leg, especially in the anterior compartment. The only treatment needed for stress fractures is rest from training. Fascial compartment pains also usually subside. If chronic fascial syndromes prevent training, fasciotomy is recommended as a reliable method to restore the athlete to normal training without pains. PMID:486888

    Patellofemoral pain (PFP) syndrome is a frequently encountered overuse disorder that involves the patellofemoral region and often presents as anterior knee pain. PFP can be difficult to diagnose. Not only do the etiology, diagnosis, and treatment remain challenging, but the terminology used to describe PFP is used inconsistently and can be confusing. Patellofemoral pain syndrome (PFPS) seems to be multifactorial, resulting from a complex interaction among intrinsic anatomic and external training factors. Although clinicians frequently make the diagnosis of PFPS, no consensus exists about its etiology or the factors most responsible for causing pain. This article discusses the pathophysiology, diagnosis, and management of PFP.

    The growing popularity of ferrets as pets has created the demand for advanced veterinary care for these patients. Pain is associated with a broad range of conditions, including acute or chronic inflammatory disease, neoplasia, and trauma, as well as iatrogenic causes, such as surgery and diagnostic procedures. Effective pain management requires knowledge and skills to assess pain, good understanding of the pathophysiology of pain, and general knowledge of pharmacologic and pharmacodynamic principles. Unfortunately, scientific studies on efficacy, pharmacokinetics, pharmacodynamics, and safety of analgesic drugs in the ferret are limited. However, basic rules on the treatment of pain and mechanisms of action, safety, and efficacy of analgesic drugs in other species can be adapted and applied to pain management in ferrets. This article aims to make an inventory of what is known on the recognition of pain in ferrets, what analgesic drugs are currently used in ferrets, and how they can be adopted in a patient-orientated pain management plan to provide effective pain relief while reducing and monitoring for unwanted side effects.

    2014-09-01

    Individuals with pelvic pain commonly present with complaints of pain located anywhere below the umbilicus radiating to the top of their thighs or genital region. The somatovisceral convergence that occurs within the pelvic region exemplifies why examination of not only the organs but also the muscles, connective tissues (fascia), and neurologic input to the region should be performed for women with pelvic pain. The susceptibility of the pelvic floor musculature to the development of myofascial pain has been attributed to unique functional demands of this muscle. Conservative interventions should be considered to address the impairments found on physical examination.

    Background Despite the widespread popularity of social media, little is known about the extent or context of pain-related posts by users of those media. Objective The aim was to examine the type, context, and dissemination of pain-related tweets. Methods We used content analysis of pain-related tweets from 50 cities to unobtrusively explore the meanings and patterns of communications about pain. Content was examined by location and time of day, as well as within the context of online social networks. Results The most common terms published in conjunction with the term “pain” included feel (n=1504), don’t (n=702), and love (n=649). The proportion of tweets with positive sentiment ranged from 13% in Manila to 56% in Los Angeles, CA, with a median of 29% across cities. Temporally, the proportion of tweets with positive sentiment ranged from 24% at 1600 to 38% at 2400, with a median of 32%. The Twitter-based social networks pertaining to pain exhibited greater sparsity and lower connectedness than did those social networks pertaining to common terms such as apple, Manchester United, and Obama. The number of word clusters in proportion to node count was greater for emotion terms such as tired (0.45), happy (0.43), and sad (0.4) when compared with objective terms such as apple (0.26), Manchester United (0.14), and Obama (0.25). Conclusions Taken together, our results suggest that pain-related tweets carry special characteristics reflecting unique content and their communication among tweeters. Further work will explore how geopolitical events and seasonal changes affect tweeters’ perceptions of pain and how such perceptions may affect therapies for pain. PMID:25843553

    2015-01-01

    BACKGROUND: Top-down characteristics of an observer influence the detection and estimation of a sufferer’s pain. A comprehensive understanding of these characteristics is important because they influence observer helping behaviours and the sufferer’s experience of pain. OBJECTIVES: To examine the hypothesis that individuals who score high in trait anxiety would perceive more intense pain in others, as indicated by a larger negative response bias, and that this association would persist after adjusting for pain catastrophizing. METHODS: Healthy young adult participants (n=99; 50 male) watched videos containing excerpts of facial expressions taken from patients with shoulder pain and were asked to rate how much pain the patient was experiencing using an 11-point numerical rating scale. Sensitivity and response bias were calculated using signal detection methods. RESULTS: Trait anxiety was a predictor of response bias after statistically adjusting for pain catastrophizing and observer sex. More anxious individuals had a proclivity toward imputing greater pain to a sufferer. CONCLUSIONS: Individuals scoring higher on trait anxiety were more likely to impute pain to a sufferer. Anxious caregivers may be better able to respond with appropriate intervention once pain behaviour is detected, or they may exacerbate symptoms by engaging in excessive palliative care and solicitous behaviour.

    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

    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.

    2007-01-01

    BACKGROUND: As the North American population ages, the prevalence of knee osteoarthritis and the surgical interventions (ie, total knee arthroplasty [TKA]) aimed at correcting pain and disability will also rise proportionally. Therefore, efforts to better understand the factors associated with surgical outcomes are warranted. To date, no studies have examined the impact of psychosocial factors on acute postoperative TKA pain. OBJECTIVES: The primary objective was to examine the associations among catastrophizing, negative mood, demographics and acute postoperative pain following TKA. Ancillary analyses examined the association of preoperative psychological variables with postoperative pain. METHODS: Patients completed questionnaire packages 2 h before their surgery and on three consecutive postoperative days while in the hospital. The questionnaire packages included the Short Form –McGill Pain Questionnaire, the Pain Catastrophizing Scale and the Shortened Version of Profile of Mood States. The Mini-Mental State Examination was also administered. Demographic data were extracted from patients’ medical charts. RESULTS: Associations among catastrophizing, negative mood and pain were established. Regressions showed that younger age predicted greater preoperative and postoperative day 1 pain; catastrophizing predicted preoperative and postoperative day 2 pain; and negative mood predicted postoperative day 3 pain. Catastrophizing and negative mood were highly correlated at several assessment points. Preoperative variables did not predict postoperative pain. CONCLUSION: These results have postoperative pain management implications. Heightened attention to psychosocial variables, such as postoperative catastrophizing and negative mood, may be useful in identifying patients at risk for greater postoperative pain. PMID:17717610

    Decades of research confirm that women have greater pain sensitivity than men. Women also show greater overall anxiety sensitivity than men. Given these differences, we hypothesized that sex differences in anxiety would explain sex differences in experienced pain and physiological responses to pain (at both spinal and cortical levels). By measuring subjective pain, state/trait anxiety, nociceptive flexion reflexes, and somatosensory evoked potentials (SEPs), it was possible to test the effects of anxiety on the processing of painful drives at different levels of the neuraxis while also documenting the role played by anxiety on sex differences in experienced pain. Results confirm that women are indeed more sensitive to pain than men. Importantly, this difference was accompanied by a significant sex difference in cortical activity (SEP amplitude) but not spinal nociceptive activity, suggesting that much of the sex difference in experienced pain is attributable to variations in thalamocortical processing and to ensuing changes in the appraisal of and/or emotional response to noxious insult. In support of this claim, we found that sex differences in cortical activity and subjective pain disappeared when trait anxiety was controlled for. This means that stable predispositions to respond with heightened apprehension contribute to baseline pain sensitivity differences between the sexes. These results indicate that the modulatory effect of affect on pain-related brain processes may explain why men and women experience painful shocks so differently. In our study, the mediating role of anxiety on sex differences in pain was tested and confirmed using path analysis.

    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.

    It is not known if the fetus can actually feel pain, but noxious stimulation during fetal life does cause detectable stress responses. These responses cause both short and long-term changes in the central nervous system, which can affect subsequent pain behaviour. Reducing the stress response is known to be beneficial in children and adults and recent evidence suggests this is also true for the fetus. However, the optimal amount of suppression required and the best method of achieving this (opioid or regional anaesthesia techniques) remain unknown. Prevention and treatment of pain is a basic human right, regardless of age, and if the technique of fetal surgery is to progress then a greater understanding of nociception and the stress response is required.

    Neuropathic pain is the most common type of pain in neuropathy. In painful polyneuropathies the pain usually has a "glove and stocking" distribution. The pain may be predominantly spontaneous, e.g., with a burning, pricking, or shooting character or characterized by evoked pain such as mechanical or cold allodynia. In the clinical setting, the prevention of painful neuropathies and treatment of underlying neuropathy remains inadequate and thus symptomatic treatment of the pain and related disability needs to be offered. Most randomized, double-blind, placebo-controlled trials (RCTs) published in painful neuropathy have been conducted in patients with diabetes and to what extent a treatment which is found effective in painful diabetic polyneuropathy can be expected to relieve other conditions like chemotherapy- or HIV-induced neuropathy is unknown. Tricyclic antidepressants (TCAs), gabapentin, pregabalin, and serotonin noradrenaline reuptake inhibitors (SNRIs) are first drug choices. In patients with localized neuropathic pain, a topical lidocaine patch may also be considered. Second-line treatments are tramadol and other opioids. New types of treatment include botulinum toxin type A (BTX-A), high-dose capsaicin patches, and cannabinoids. Other types of anticonvulsant drugs such as lamotrigine, oxcarbazepine, and lacosamide have a more questionable efficacy in painful polyneuropathy but may have an effect in a subgroup of patients. Combination therapy may be considered in patients with insufficient effect from one drug. Treatment is usually a trial-and-error process and has to be individualized to the single patient, taking into account all comorbidities such as possible concomitant depression, anxiety, diseases, and drug interactions. Side-effects to antidepressants include dry mouth, nausea, constipation, orthostatic hypotension, and sedation. ECG should always be obtained prior to treatment with TCAs, which also should not be used in patients with cardiac

    Objective Preoperative determinants of pain duration following surgery are poorly understood. We identified preoperative predictors of prolonged pain after surgery in a mixed surgical cohort. Methods We conducted a prospective longitudinal study of patients undergoing mastectomy, lumpectomy, thoracotomy, total knee replacement, or total hip replacement. We measured preoperative psychological distress and substance use, and then measured pain and opioid use after surgery until patients reported the cessation of both opioid consumption and pain. The primary endpoint was time to opioid cessation, and those results have been previously reported. Here we report preoperative determinants of time to pain resolution following surgery in Cox proportional hazards regression. Results Between January 2007 and April 2009 we enrolled 107 of 134 consecutively approached patients undergoing the aforementioned surgical procedures. In the final multivariate model, preoperative self-perceived risk of addiction predicted more prolonged pain. Unexpectedly, anxiety sensitivity predicted more rapid pain resolution after surgery. Each one-point increase (on a four point scale) of self-perceived risk of addiction was associated with a 38% (95% CI 3 - 61) reduction in the rate of pain resolution (p= 0.04). Furthermore, higher anxiety sensitivity was associated with an 89% (95% CI 23–190) increased rate of pain resolution (p=0.004). Conclusions Greater preoperative self-perceived risk of addiction, and lower anxiety sensitivity predicted a slower rate of pain resolution following surgery. Each of these factors was a better predictor of pain duration than preoperative depressive symptoms, PTSD symptoms, past substance use, fear of pain, gender, age, preoperative pain, or preoperative opioid use.

    With over four million deliveries annually in the United States alone and a constant increase in cesarean delivery rate, childbirth is likely to have a huge impact on the occurrence of acute and possibly chronic postpartum pain. Recent awareness that chronic pain may occur after childbirth has prompted clinicians and researchers to investigate this topic. Current evidence points towards a relatively low incidence of chronic pain after cesarean delivery, with rates ranging between 1% and 18%. To provide a potential mechanistic explanation for the relatively low occurrence of chronic pain after cesarean delivery compared with that after other types of surgery, it has been proposed that endogenous secretion of oxytocin may confer specific protection. Clinical interventions to reduce the incidence and severity of chronic post-surgical pain have not been consistently effective. Likely explanations are that the drugs that have been investigated were truly ineffective or that the effect was too modest because with a low incidence of chronic pain, studies were likely to be underpowered and failed to demonstrate an effect. In addition, since not all women require preventive therapies, preoperative testing that may identify women vulnerable to pain may be highly beneficial. Further research is needed to identify valid models that predict persistent pain to allow targeted interventions to women most likely to benefit from more tailored anti-hyperalgesic therapies.

    Severe pain is highly prevalent, with rates of 40% to 70% in patients with advanced cancer, liver disease, heart failure, human immunodeficiency virus, and renal failure. Wide variations in pain assessment and reporting methods and the measurement of multiple symptoms should be addressed in future studies. Regarding psychological approaches, determining whether hypnotherapy or other individual psychotherapeutic interventions reduce pain and/or psychological distress in a palliative care population is difficult. Interest is increasing in the concept of demoralization syndromes and the role of posttraumatic stress disorder in modulating responses to pain at the end of life. We review evidence from multiple studies that the use of rehabilitative therapy improves functional status and pain control among patients with advanced cancer, and we raise the possibility that rehabilitation therapy will be helpful in patients with other advanced diseases. We summarize ongoing clinical trials of electronic order sets, clinical care pathways, and care management pathways to improve pain management in palliative care. Wagner's Chronic Illness Model provides a way of analyzing how healthcare systems can be changed to provide adequate and continuing pain management in palliative care. Much work remains to ensure that pain is recognized, treated, and monitored effectively.

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

    Chronic pain after laparoscopic cholecystectomy is related to postoperative pain during the first postoperative week, but it is unknown which components of the early pain response is important. In this prospective study, 100 consecutive patients were examined preoperatively, 1 week postoperatively, and 3, 6, and 12 months postoperatively for pain, psychological factors, and signs of hypersensitivity. Overall pain, incisional pain (somatic pain component), deep abdominal pain (visceral pain component), and shoulder pain (referred pain component) were registered on a 100-mm visual analogue scale during the first postoperative week. Nine patients developed chronic unexplained pain 12 months postoperatively. In a multivariate analysis model, cumulated visceral pain during the first week and number of preoperative biliary pain attacks were identified as independent risk factors for unexplained chronic pain 12 months postoperatively. There were no consistent signs of hypersensitivity in the referred pain area either pre- or postoperatively. There were no significant associations to any other variables examined. The risk of chronic pain after laparoscopic cholecystectomy is relatively low, but significantly related to the visceral pain response during the first postoperative week.

    This study examined whether self-efficacy mediated the relationship between pain catastrophizing and pain and disability. Participants were 192 individuals diagnosed with osteoarthritis (OA) of the knees who were overweight or obese. Multiple mediator analyses were conducted to simultaneously test self-efficacy for pain control, physical function, and emotional symptoms as mediators while controlling for demographic and medical status variables. Higher pain catastrophizing was associated with lower self-efficacy in all three domains (ps< .05). Self-efficacy for pain control fully mediated the relationship between pain catastrophizing and pain (β=.08, Sobel test Z=1.97, p<.05). The relationship between pain catastrophizing and physical disability was fully mediated by self-efficacy for physical function (β=.06, Sobel test Z=1.95, p=.05). Self-efficacy for emotional symptoms partially mediated the relationship between pain catastrophizing and psychological disability (β=.12, Sobel test Z=2.92, p<.05). These results indicate that higher pain catastrophizing contributed to greater pain and disability via lower domain-specific self-efficacy. Efforts to reduce pain and improve functioning in OA patients should consider addressing pain catastrophizing and domain specific self-efficacy. Pain catastrophizing may be addressed through cognitive therapy techniques and self-efficacy may be enhanced through practice of relevant skills and personal accomplishments. Perspective This paper found that higher pain catastrophizing contributed to great pain and disability via domain specific self-efficacy. These results suggest that treatment efforts to reduce pain and improve functioning in OA patients who are overweight or obese should consider addressing both pain catastrophizing and self-efficacy.

Pain arising from these structures is often mistaken for angina pectoris, pleurisy or other serious disorders. In this article the clinical features, pathogenesis and management of the various musculoskeletal chest wall disorders are discussed. The more common causes are costochondritis, traumatic muscle pain, trauma to the chest wall, “fibrositis” syndrome, referred pain, psychogenic regional pain syndrome, and arthritis involving articulations of the sternum, ribs and thoracic spine. Careful analysis of the history, physical findings and results of investigation is essential for precise diagnosis and effective treatment. ImagesFig. 3Fig. 4Fig. 5 PMID:4027804

  15. An archaeology of pain

    NASA Astrophysics Data System (ADS)

    Gruber, Dennis Michael

    Pain is a discursive construct of science and medicine. Through the discourses of biopower and technoscience pain is used to construct and maintain the social body. Biopower and technoscience are discursive practices that are enveloped within the disciplines of Western society. Specifically, the disciplines of education, science, and medicine use biopower and technoscience to normalize the body and construct binaries which create the abnormal. The cyborg is a discursive practice used to implode the binaries of the disciplines which maintain the social body. Through the implosion of binaries, the binary of mind/body is no longer plausible in the explanation of pain. Neuropathic chronic pain and phantom limb pain become cyborg discourses which operate to deconstruct the pedagogies of science and medicine.

    Abdominal pain is among the most frequent ailments reported in the office setting and can account for up to 40% of ailments in the ambulatory practice. Also, it is in the top three symptoms of patients presenting to emergency departments (ED) and accounts for 5-10% of all ED primary presenting ailments. There are several common sources for acute abdominal pain and many for subacute and chronic abdominal pain. This article explores the history-taking, initial evaluation, and examination of the patient presenting with acute abdominal pain. The goal of this article is to help differentiate one source of pain from another. Discussion of acute cholecystitis, pancreatitis, appendicitis, ectopic pregnancy, diverticulitis, gastritis, and gastroenteritis are undertaken. Additionally, there is discussion of common laboratory studies, diagnostic studies, and treatment of the patient with the above entities.

    Groin pain in young athletes is a common problem, accounting for significant downtime in sports participation. It can be difficult to make the correct diagnosis as groin pain has a wide differential diagnosis, which encompasses acute as well as chronic causative factors. In this article this is illustrated by presenting three cases of patients who attended our hospital. In all three cases the main complaint was sports-related groin pain, and the patients presented with very similar symptoms. However, after further investigation the patients were diagnosed with three very different types of injury: sportsman's hernia; hip labral tear; and pubic osteitis. This emphasises the need for every general practitioner and medical specialist to understand that there is a wide differential diagnosis for groin pain in athletes, in order to be able to implement specific therapy targeting the actual cause of groin pain.

    Offspring of parents with chronic pain may be at risk for poorer outcomes than offspring of healthy parents. The objective of this research was to provide a comprehensive mixed-methods systematic synthesis of all available research on outcomes in offspring of parents with chronic pain. A systematic search was conducted for published articles in English examining pain, health, psychological, or family outcomes in offspring of parents with chronic pain. Fifty-nine eligible articles were identified (31 population-based, 25 clinical, 3 qualitative), including offspring from birth to adulthood and parents with varying chronic pain diagnoses (eg, mixed pain samples, arthritis). Meta-analysis was used to synthesize the results from population-based and clinical studies, while meta-ethnography was used to synthesize the results of qualitative studies. Increased pain complaints were found in offspring of mothers and of fathers with chronic pain and when both parents had chronic pain. Newborns of mothers with chronic pain were more likely to have adverse birth outcomes, including low birthweight, preterm delivery, caesarian section, intensive care admission, and mortality. Offspring of parents with chronic pain had greater externalizing and internalizing problems and poorer social competence and family outcomes. No significant differences were found on teacher-reported externalizing problems. The meta-ethnography identified 6 key concepts (developing independence, developing compassion, learning about health and coping, missing out, emotional health, and struggles communicating with parents). Across study designs, offspring of parents with chronic pain had poorer outcomes than other offspring, although the meta-ethnography noted some constructive impact of having a parent with chronic pain.

    Breakthrough cancer pain has been defined as a transitory increase in pain intensity that occurs despite relatively stable and adequately controlled background pain. More than half of cancer patients with chronic pain suffer by some form of breakthrough cancer pain. The management of breakthrough cancer pain is comprehensive and includes pharmacological and nonpharmacological approaches. The principal treatment strategies are optimization of regular analgesic medication combined with effective rescues medication. The new transmucosal forms of fentanyl represent an important improvement in our treatment options.

  5. Somatosensory Profiles but Not Numbers of Somatosensory Abnormalities of Neuropathic Pain Patients Correspond with Neuropathic Pain Grading

    Due to the lack of a specific diagnostic tool for neuropathic pain, a grading system to categorize pain as ‘definite’, ‘probable’, ‘possible’ and ‘unlikely’ neuropathic was proposed. Somatosensory abnormalities are common in neuropathic pain and it has been suggested that a greater number of abnormalities would be present in patients with ‘probable’ and ‘definite’ grades. To test this hypothesis, we investigated the presence of somatosensory abnormalities by means of Quantitative Sensory Testing (QST) in patients with a clinical diagnosis of neuropathic pain and correlated the number of sensory abnormalities and sensory profiles to the different grades. Of patients who were clinically diagnosed with neuropathic pain, only 60% were graded as ‘definite’ or ‘probable’, while 40% were graded as ‘possible’ or ‘unlikely’ neuropathic pain. Apparently, there is a mismatch between a clinical neuropathic pain diagnosis and neuropathic pain grading. Contrary to the expectation, patients with ‘probable’ and ‘definite’ grades did not have a greater number of abnormalities. Instead, similar numbers of somatosensory abnormalities were identified for each grade. The profiles of sensory signs in ‘definite’ and ‘probable’ neuropathic pain were not significantly different, but different from the ‘unlikely’ grade. This latter difference could be attributed to differences in the prevalence of patients with a mixture of sensory gain and loss and with sensory loss only. The grading system allows a separation of neuropathic and non-neuropathic pain based on profiles but not on the total number of sensory abnormalities. Our findings indicate that patient selection based on grading of neuropathic pain may provide advantages in selecting homogenous groups for clinical research. PMID:22927981

    Objective To examine pain self-efficacy and pain acceptance in relation to functioning in pediatric patients with chronic headache. Methods Participants were 209 youth aged 8–17 years who presented for a multidisciplinary pediatric headache clinic evaluation. They completed measures of pain self-efficacy and pain acceptance and a standard battery of clinical measures including indicators of emotional functioning. Results Pain self-efficacy and acceptance were associated with less disability, better school functioning, and fewer depressive symptoms. While taking into account several demographic and pain-related variables, pain self-efficacy had a greater association with less functional disability, while pain acceptance had a greater association with less depressive symptoms and better school functioning. Conclusions These findings indicate that both resilience processes can serve to positively interact with functioning and symptoms of depression. Ultimately, this study suggests that higher levels of pain self-efficacy and pain acceptance in an individual experiencing pain are associated with more positive outcomes. PMID:25324532

    Pain relief is a management problem for many patients, their families, and the medical professionals caring for them. Although everyone experiences pain to some degree, responses to it vary from one person to another. Recognizing and specifying someone else’s pain is clinically a well know challenge. Research on the biology and neurobiology of pain has given us a relationship between spirituality and pain. There is growing recognition that persistent pain is a complex and multidimensional experience stemming from the interrelations among biological, psychological, social, and spiritual factors. Patients with pain use a number of cognitive and behavioral strategies to cope with their pain, including religious/spiritual factors, such as prayers, and seeking spiritual support to manage their pain. This article provides an overview of the complex phenomenon of pain, with a focus on spiritual and religious issues in pain management. PMID:26973914

    Because of the high prevalence of back pain experienced by U.S. Army helicopter pilots, a study was conducted to ascertain the feasibility of reproducing these symptoms in the laboratory. A mock-up of a UH-1H seat and control configuration was mounted to a multi-axis vibration simulator (MAVS). Eleven subjects were tested on the apparatus for two 120-min periods. During one period, the MAVS was programmed to reproduce vibrations recorded from a UH-1H in cruise flight. The subjects received no vibration during the other test period. All subjects reported back pain which they described as identical to the pain they experience during flight, during one or more of their test periods. There was no statistical difference between the vibration and nonvibration test conditions (p greater than 0.05) in terms of time of onset of pain or intensity of pain as measured by a visual analog scale. It appears the vibration at the frequencies and amplitudes tested plays little or no role in the etiology of the back symptoms reported by these pilots. It is proposed that the primary etiological factor for these symptoms is the poor posture pilots are obliged to assume for extended periods while operating helicopters.

    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.

    Mental defeat is a psychological construct that has recently been applied to characterize the experience of chronic pain. Elevated levels of mental defeat have been identified in patients with chronic pain, and while its presence distinguishes treatment seeking from non-treatment seeking individuals, the link between mental defeat and disability in chronic pain is yet to be established. The current study investigated the extent to which mental defeat is associated with pain-related interference, distress and disability. A total of 133 participants completed the Pain Self Perception Scale that assessed mental defeat in relation to pain. Moreover, the participants were asked to complete a set of questionnaires that measured pain interference, distress, disability and other demographic (age, body mass index), clinical (pain intensity) and psychological (catastrophizing, worry, rumination and health anxiety) predictors of disability. Mental defeat was found to be strongly correlated with pain interference, sleep disturbance, anxiety, depression, functional disability and psychosocial disability. These correlations remained significant even when pain intensity and demographic variables were partialled out. Relative to chronic pain patients with lower levels of mental defeat, those with higher levels of mental defeat reported greater degree of pain interference, distress and disability. In a series of regression analyses, mental defeat emerged as the strongest predictor of pain interference, depression and psychosocial disability, whereas catastrophizing was the best predictor of sleep interference, anxiety and functional disability. These findings suggest that mental defeat may be an important mediator of distress and disability in chronic pain. Theoretical and clinical implications are discussed.

    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.

    Debate continues regarding the influence of litigation on pain outcomes after motor vehicle collision (MVC). In this study we enrolled European Americans presenting to the emergency department (ED) in the hours after MVC (n=948). Six weeks later, participants were interviewed regarding pain symptoms and asked about their participation in MVC-related litigation. The incidence and predictors of neck pain and widespread pain 6weeks after MVC were compared among those engaged in litigation (litigants) and those not engaged in litigation (nonlitigants). Among the 859 of 948 (91%) participants completing 6-week follow-up, 711 of 849 (83%) were nonlitigants. Compared to nonlitigants, litigants were less educated and had more severe neck pain and overall pain, and a greater extent of pain at the time of ED evaluation. Among individuals not engaged in litigation, persistent pain 6weeks after MVC was common: 199 of 711 (28%) had moderate or severe neck pain, 92 of 711 (13%) had widespread pain, and 29 of 711 (4%) had fibromyalgia-like symptoms. Incidence of all 3 outcomes was significantly higher among litigants. Initial pain severity in the ED predicted pain outcomes among both litigants and nonlitigants. Markers of socioeconomic disadvantage predicted worse pain outcomes in litigants but not nonlitigants, and individual pain and psychological symptoms were less predictive of pain outcomes among those engaged in litigation. These data demonstrate that persistent pain after MVC is common among those not engaged in litigation, and provide evidence for bidirectional influences between pain outcomes and litigation after MVC.

    Nerve impairment is a key clinical aspect of leprosy and may present the distribution of mononeuropathy or multiple nerve trunks, small cutaneous nerve fibers, and free nerve endings. The clinical range of leprosy is determined by individual cell-mediated immune response to infection that also may play a role in different types of pain syndromes in leprosy. Previous studies reported a high prevalence of neuropathic pain in leprosy. In an Ethiopian study with 48 patients, pure nociceptive pain was experienced by 43% of patients and pure neuropathic pain (NeP) by 11% of patients. In an Indian study, 21.8% of leprosy patients had pain with neuropathic characteristics. These rates underlie the need to develop tools for the early diagnosis and detection of infection and its complications, such as nerve damage and pain. In a larger sample with leprosy-associated NeP (n = 90), we have applied the Douleur Neuropathique en 4 questions (DN4) and found sensitivity = 97.1% and specificity = 57.9%. The high sensitivity of this tool in leprosy patients suggests that it could be a valuable tool to screen for neuropathic pain in this population and could be used as part of health care programs aimed at detecting, treating, and rehabilitating leprosy in endemic areas.

  17. Low back pain.

    Low back pain is a leading cause of disability. It occurs in similar proportions in all cultures, interferes with quality of life and work performance, and is the most common reason for medical consultations. Few cases of back pain are due to specific causes; most cases are non-specific. Acute back pain is the most common presentation and is usually self-limiting, lasting less than three months regardless of treatment. Chronic back pain is a more difficult problem, which often has strong psychological overlay: work dissatisfaction, boredom, and a generous compensation system contribute to it. Among the diagnoses offered for chronic pain is fibromyalgia, an urban condition (the diagnosis is not made in rural settings) that does not differ materially from other instances of widespread chronic pain. Although disc protrusions detected on X-ray are often blamed, they rarely are responsible for the pain, and surgery is seldom successful at alleviating it. No single treatment is superior to others; patients prefer manipulative therapy, but studies have not demonstrated that it has any superiority over others. A WHO Advisory Panel has defined common outcome measures to be used to judge the efficacy of treatments for studies. PMID:14710509

    Danziger, N; Willer, J-C

    2009-02-01

    Congenital insensitivity to pain (CIP) is a rare syndrome with various clinical expressions, characterized by a dramatic impairment of pain perception since birth. In the 1980s, progress in nerve histopathology allowed to demonstrate that CIP was almost always a manifestation of hereditary sensory and autonomic neuropathies (HSAN) involving the small-calibre (A-delta and C) nerve fibres which normally transmit nociceptive inputs along sensory nerves. Identification of the genetic basis of several clinical subtypes has led to a better understanding of the mechanisms involved, emphasizing in particular the crucial role of nerve growth factor (NGF) in the development and survival of nociceptors. Recently, mutations of the gene coding for the sodium channel Nav1.7--a voltage-dependent sodium channel expressed preferentially on peripheral nociceptors and sympathetic ganglia--have been found to be the cause of CIP in patients showing a normal nerve biopsy. This radical impairment of nociception mirrors the hereditary pain syndromes associated with "gain of function" mutations of the same ion channel, such as familial erythromelalgia and paroxysmal extreme pain disorder. Future research with CIP patients may identify other proteins specifically involved in nociception, which might represent potential targets for chronic pain treatment. Moreover, this rare clinical syndrome offers the opportunity to address interesting neuropsychological issues, such as the role of pain experience in the construction of body image and in the empathic representation of others' pain.

  19. Pain in autoimmune disorders.

    Most autoimmune diseases are associated with pathological pain development. Autoimmune diseases with pathological pain include complex regional pain syndrome, rheumatoid arthritis, and Guillian-Barré syndrome to name a few. The present Review explores research linking the immune system to the development of pathological pain in autoimmune diseases. Pathological pain has been linked to T-cell activation and the release of cytokines from activated microglia in the dorsal horn of the spinal cord. New research on the role of autoantibodies in autoimmunity has generated insights into potential mechanisms of pain associated with autoimmune disease. Autoantibodies may act through various mechanisms in autoimmune disorders. These include the alteration of neuronal excitability via specific antigens such as the voltage-gated potassium channel complexes or by mediating bone destruction in rheumatoid arthritis. Although more research must be done to understand better the role of autoantibodies in autoimmune disease related pain, this may be a promising area of research for new analgesic therapeutic targets. © 2016 Wiley Periodicals, Inc.

  20. Impaired neck motor function and pronounced pain-related fear in helicopter pilots with neck pain - a clinical approach.

    PubMed

    2008-08-01

    There is recognition that neck pain is a significant clinical problem in military aviation. In the present trial, the objectives were to explore neck motor function and pain-related fear in pilots with differing progression of neck pain. Seventy-two military helicopter pilots were enrolled: 20 had acute ongoing neck pain, 27 had subacute pain, and 25 were pain-free controls. Neck-flexor electromyography activity (root-mean-square) during staged active craniocervical flexion, median power frequency during sustained neck-flexor contraction, cervical range of motion, rating of perceived exertion after sustained flexor contraction, and rated fear-avoidance beliefs about physical activity were estimated. Main effects emerged for flexor activity, fear-avoidance and range of motion, but not for median frequency variables or perceived exertion. Post hoc testing showed that, compared to controls, both pain groups had greater flexor activity at higher stages of craniocervical flexion while the acute group had higher fear-avoidance and less range of motion in axial rotation and flexion-extension, all P<0.01. Discriminant regression revealed a sensitivity/specificity of 87%/71% (neck-pain/controls), with the flexor activity superior. The results indicate that altered neuromotor synergies are present at different progressions of pain. The tracing of such aberrant activity and fear-avoidance beliefs is suggested in future screening and neck intervention research.

  1. Painful neuropathy: Mechanisms.

    PubMed

    Lee-Kubli, Corinne A; Calcutt, Nigel A

    2014-01-01

    Painful neuropathy, like the other complications of diabetes, is a growing healthcare concern. Unfortunately, current treatments are of variable efficacy and do not target underlying pathogenic mechanisms, in part because these mechanisms are not well defined. Rat and mouse models of type 1 diabetes are frequently used to study diabetic neuropathy, with rats in particular being consistently reported to show allodynia and hyperalgesia. Models of type 2 diabetes are being used with increasing frequency, but the current literature on the progression of indices of neuropathic pain is variable and relatively few therapeutics have yet been developed in these models. While evidence for spontaneous pain in rodent models is sparse, measures of evoked mechanical, thermal and chemical pain can provide insight into the pathogenesis of the condition. The stocking and glove distribution of pain tantalizingly suggests that the generator site of neuropathic pain is found within the peripheral nervous system. However, emerging evidence demonstrates that amplification in the spinal cord, via spinal disinhibition and neuroinflammation, and also in the brain, via enhanced thalamic activity or decreased cortical inhibition, likely contribute to the pathogenesis of painful diabetic neuropathy. Several potential therapeutic strategies have emerged from preclinical studies, including prophylactic treatments that intervene against underlying mechanisms of disease, treatments that prevent gains of nociceptive function, treatments that suppress enhancements of nociceptive function, and treatments that impede normal nociceptive mechanisms. Ongoing challenges include unraveling the complexity of underlying pathogenic mechanisms, addressing the potential disconnect between the perceived location of pain and the actual pain generator and amplifier sites, and finding ways to identify which mechanisms operate in specific patients to allow rational and individualized choice of targeted therapies.

Sometimes this may be true, but neither the individual patients nor the accumulated scientific evidence deserve such a routine dismissal. In this editorial I will review issues of responsibility, the nature of referred pain and referred tenderness, evidence for the value of tender point examination as an objective measure, techniques of assessment of the cervical spine, techniques of assessment of pain behaviour, and the determinants of the specific symptom patterns associated with cervical injury.

    Myofascial pelvic pain is fraught with many unknowns. Is it the organs of the pelvis, is it the muscles of the pelvis, or is the origin of the pelvic pain from an extrapelvic muscle? Is there a single source or multiple? In this state of confusion what is the best way to manage the many symptoms that can be associated with myofascial pelvic pain. This article reviews current studies that attempt to answer some of these questions. More questions seem to develop as each study presents its findings.

    Pediatric chronic pain is a major health problem commonly associated with impaired functioning. There is a great need for more knowledge regarding the complex interplay between demographic variables such as age and gender, pain, and functioning in pediatric chronic pain. Objective: The objective of the study was to investigate if; (1) pediatric chronic pain patients with high and low levels of functioning differ in demographic variables, pain, and pain interference; (2) explore the mediating function of pain interference in the relationship between pain and functioning (i.e., depression and functional disability). Method: The study includes a consecutive sample of children and adolescents referred to a tertiary pain clinic due to chronic pain (n = 163). Cross-sectional data was analyzed to investigate the interrelationships between variables. Analyses of indirect effects were used to assess the impact of pain interference on the relation between pain and depression. Results: Findings illustrate high levels of depression, school absence and pain interference in this sample. Furthermore, pain interference mediated the relationship between pain and depression. Conclusion: Thus, this study adds to the growing support of findings suggesting that functioning and pain interference should be routinely assessed in pediatric chronic pain and a central target in treatment. Particularly, these findings imply a need for interventions specifically aimed at improved functioning for patients with chronic debilitating pain. PMID:28082931

  6. Pain and Psychological Outcomes After Rehabilitative Treatment for a Woman With Chronic Pelvic Pain With Stage III Cervical Cancer: A Case Report

    2016-01-01

    Background Chronic pelvic pain and sexual dysfunction are adverse effects of treatment of cervical cancer. Surgery and radiation therapies may result in soft tissue pain and dysfunction, including spasms and trigger points of the pelvic floor muscles that result in pain. In addition to physical restrictions, negative mood associated with pain is believed to intensify and prolong the pain experience. Study Design The purpose of this case report was to describe outcomes of pelvic physical therapy in a 58-year-old woman with chronic pelvic pain after medical treatments for cervical cancer. Case Description The patient reported dyspareunia, hip pain, and lower abdominal, pelvic pain, and fatigue with activities lasting greater than 30 minutes. Interventions included pelvic floor massage, dilator use, and patient education. Symptoms were assessed at baseline and completion of physical therapy, using the Female Sexual Function Index, Fear of Pain Questionnaire–III, Pain Catastrophizing Scale, and Numerical Pain Rating Scale. Outcomes The Female Sexual Function Index score decreased from 7.8 to 2.8, the Fear of Pain Questionnaire– III score decreased from 85 to 73, the Pain Catastrophizing Scale score decreased from 18 to 8, and lower abdominal and pelvic pain decreased from 4 of 10 to 0 of 10, while bilateral hip pain remained at 4 of 10. In addition, she exhibited increased tolerance to mechanical pressure, evidenced by progression in size of a vaginal dilator. Discussion These results suggest that pelvic physical therapy may be useful in treating chronic pelvic pain after cervical cancer treatments and may also help decrease the magnitude of negative mood aspects such as pain-related fear and catastrophizing.

  8. [Pharmacotherapy for neuropathic pain caused by injury to the afferent nerve fibers].

    PubMed

    Weber, W E

    2001-04-28

    Phantom pain, a form of neuropathic pain, is caused by damage to somatosensible afferent nerve fibres in the peripheral or central nervous system. Often, the pain cannot be satisfactorily treated with nonsteroidal anti-inflammatory drugs. Dependent on the underlying mechanism the pain is treated with either antidepressants (for more or less continuous pain) or anti-epileptics (for paroxysmal pain). Of the antidepressants, the tricyclic antidepressants are the best studied and most prescribed. The activity of new drugs, such as the selective serotonin reuptake inhibitor paroxetine as well as venlafaxine, has yet to be clearly shown. Of the anti-epileptics, carbamazepine and phenytoin are the most prescribed. New drugs which provide greater pain relief than the placebo are oxcarbazepine, gabapentine and lamotrigine. Other effective drugs for phantom pain are: gamma-butyric acid agonists (baclofen), opiates (morphine preparations with a regulated release; phentanyl patch), the N-methyl-D-aspartate receptor antagonist amantadine, transdermally administered clonidine and locally applied lidocaine.

  9. History of physical and sexual abuse in women with chronic pelvic pain.

    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.

  12. Pain and nociception: mechanisms of cancer-induced bone pain.

    PubMed

    Falk, Sarah; Dickenson, Anthony H

    2014-06-01

    Cancer pain, especially pain caused by metastasis to bone, is a severe type of pain, and unless the cause and consequences can be resolved, the pain will become chronic. As detection and survival among patients with cancer have improved, pain has become an increasing challenge, because traditional therapies are often only partially effective. Until recently, knowledge of cancer pain mechanisms was poor compared with understanding of neuropathic and inflammatory pain states. We now view cancer-induced bone pain as a complex pain state involving components of both inflammatory and neuropathic pain but also exhibiting elements that seem unique to cancer pain. In addition, the pain state is often unpredictable, and the intensity of the pain is highly variable, making it difficult to manage. The establishment of translational animal models has started to reveal some of the molecular components involved in cancer pain. We present the essential pharmacologic and neurobiologic mechanisms involved in the generation and continuance of cancer-induced bone pain and discuss these in the context of understanding and treating patients. We discuss changes in peripheral signaling in the area of tumor growth, examine spinal cord mechanisms of sensitization, and finally address central processing. Our aim is to provide a mechanistic background for the sensory characteristics of cancer-induced bone pain as a basis for better understanding and treating this condition.

    2014-12-01

    Hip pain in the adolescent athlete is a common source of functional impairment and can limit athletic performance. In the past, many intra- and extra-articular hip abnormalities went unrecognized and were left untreated because of insufficient diagnostic imaging and limited surgical options. However, over the past 20 years, there has been a tremendous expansion research, and the understanding of the etiology of hip pain among such athletes has grown. Improvements in imaging modalities and technical innovations have led to greater diagnostic insights and creative new treatment strategies. This article explores the etiology and treatment of hip pain in the adolescent athlete.

  14. Role of satellite glial cells in gastrointestinal pain.

    PubMed

    Hanani, Menachem

    2015-01-01

    Gastrointestinal (GI) pain is a common clinical problem, for which effective therapy is quite limited. Sensations from the GI tract, including pain, are mediated largely by neurons in the dorsal root ganglia (DRG), and to a smaller extent by vagal afferents emerging from neurons in the nodose/jugular ganglia. Neurons in rodent DRG become hyperexcitable in models of GI pain (e.g., gastric or colonic inflammation), and can serve as a source for chronic pain. Glial cells are another element in the pain signaling pathways, and there is evidence that spinal glial cells (microglia and astrocytes) undergo activation (gliosis) in various pain models and contribute to pain. Recently it was found that satellite glial cells (SGCs), the main type of glial cells in sensory ganglia, might also contribute to chronic pain in rodent models. Most of that work focused on somatic pain, but in several studies GI pain was also investigated, and these are discussed in the present review. We have shown that colonic inflammation induced by dinitrobenzene sulfonic acid (DNBS) in mice leads to the activation of SGCs in DRG and increases gap junction-mediated coupling among these cells. This coupling appears to contribute to the hyperexcitability of DRG neurons that innervate the colon. Blocking gap junctions (GJ) in vitro reduced neuronal hyperexcitability induced by inflammation, suggesting that glial GJ participate in SGC-neuron interactions. Moreover, blocking GJ by carbenoxolone and other agents reduces pain behavior. Similar changes in SGCs were also found in the mouse nodose ganglia (NG), which provide sensory innervation to most of the GI tract. Following systemic inflammation, SGCs in these ganglia were activated, and displayed augmented coupling and greater sensitivity to the pain mediator ATP. The contribution of these changes to visceral pain remains to be determined. These results indicate that although visceral pain is unique, it shares basic mechanisms with somatic pain

    This study examined the relationships among anxiety sensitivity (AS), catastrophizing, somatization, and pain in 240 non-clinical children (121 girls; mean age = 12.7 years). Children with pain problems (n = 81; 33.8%) reported greater AS and catastrophizing (p’s < .01) relative to children without pain problems. AS but not catastrophizing was significantly associated with current pain. However, both AS and catastrophizing were significantly associated with somatization. AS and catastrophizing represent related but partially distinct cognitive constructs that may be targeted by interventions aimed at alleviating pain and somatization in children. PMID:19858329

    These retrospective analyses of daily mean pain scores from nine placebo-controlled trials of pregabalin at 150, 300, or 600 mg/day (pregabalin, n = 1205; placebo, n = 772) examined time to significant reduction of pain during the first 2 weeks of treatment of painful diabetic peripheral neuropathy and postherpetic neuralgia. Time to onset of reduction in pain-defined as the first day for which patients treated with pregabalin had significant reductions (P < 0.05) in mean pain score compared with the placebo group for that day and the subsequent day-was calculated for all treatment groups demonstrating statistically significant reduction in pain at trial end point. The time to a 1-point or greater improvement in mean pain score was measured for each patient who was a responder at end point (30% or greater improvement in mean pain score). In seven of the nine trials (representing 11 of 14 pregabalin arms), significant reduction in pain was achieved at end point. The time to onset for reduction in pain was treatment Day 1 or 2 in nine of these successful treatment arms. Individual responder analysis confirmed that responders in the pregabalin groups reported a 1-point or greater pain reduction earlier than responders in placebo groups (P < 0.0001). However, this analysis is not a direct estimate of the likelihood that an individual patient would experience noticeable pain relief by the end of the second day. Overall, for patients who will respond to pregabalin, statistically significant and sustained reduction of pain associated with diabetic peripheral neuropathy and posttherapeutic neuralgia occurs early, usually by the end of 2 days of pregabalin treatment.

  18. Intrathecal clonidine and adenosine: effects on pain and sensory processing in patients with chronic regional pain syndrome.

    2015-01-01

    Chronic pain may be accompanied by hyperalgesia and allodynia, and analgesic interventions may reduce these hypersensitivity phenomena. Preclinical data suggest that intrathecal clonidine and adenosine reduce hypersensitivity, but only clonidine reduces pain; therefore, we tested the effects of these interventions in patients with chronic pain. Twenty-two subjects with pain and hyperalgesia in a lower extremity from complex regional pain syndrome were recruited in a double-blind crossover study to receive intrathecal clonidine, 100 μg, or adenosine, 2 mg. Primary outcome measure was proportion with ≥30% reduction in pain 2 hours after injection, and secondary measures were pain report, areas of hypersensitivity, and temporal summation to heat stimuli. Treatments did not differ in the primary outcome measure (10 met success criterion after clonidine administration and 5 after adenosine administration), although they did differ in pain scores over time, with clonidine having a 3-fold greater effect (P = 0.014). Both drugs similarly reduced areas of hyperalgesia and allodynia by approximately 30% and also inhibited temporal summation. The percentage change in pain report did not correlate with the percentage change in areas of hyperalgesia (P = 0.09, r = 0.08) or allodynia (P = 0.24, r = 0.24) after drug treatment. Both intrathecal clonidine and adenosine acutely inhibit experimentally induced and clinical hypersensitivity in patients with chronic regional pain syndrome. Although these drugs do not differ in analgesia by the primary outcome measure, their difference in effect on pain scores over time and lack of correlation between effect on pain and hypersensitivity suggest that analgesia does not parallel antihyperalgesia with these treatments.

  19. No pain, no gain: pain behaviour in the armed forces.

    PubMed

    Harper, Phil

    Pain is a unique phenomenon that is difficult to express and is influenced by many different factors, including cultural expectations. A dichotomy exists within the British Armed Forces between pain being seen as necessary--the "no pain, no gain" view--and the opposite image of stoical service personnel who suppress their emotions--the "roughie-toughie" image. This dichotomy was explored through an ethnographic study of pain behaviour experienced during a training course. Pain behaviour was found to be consistent with cultural expectations and this supported the "no pain, no gain" perspective. Physical and psychological pain were expressed differently, reinforcing the western, scientific mind-body dichotomy. In addition, personnel frequently tried to suppress their pain and this supported the "roughie-toughie" philosophy. Thus, pain expression varies according to the context in which it occurs. Nurses need to be aware of this to ensure they interpret and manage their patients' pain appropriately.

    Fragility vertebral fractures often are associated with chronic back pain controlled by analgesic compounds. Capacitive coupling electrical stimulation is a type of electrical stimulation technology approved by the US FDA to noninvasively enhance fracture repair and spinal fusion. These uses suggest it would be a possible treatment for patients with back pain attributable to vertebral fractures. We therefore randomized 51 postmenopausal women with multiple fractures and chronic pain to the use of one of two indistinguishable devices delivering either the standard capacitive coupling electrical stimulation by Osteospine™ (active group) or low intensity pulse (control group). Twenty patients of the active group and 21 of the control group (80%) completed the study for a total duration of 3 months. The mean visual analog scale values for pain and the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) scores improved in both groups. We observed a relationship between hours of treatments and reductions in pain intensity only in the active group. Capacitive coupling electrical stimulation was not more effective than control treatment when comparing mean visual analog scale pain and QALEFFO scores in the two groups and when adjusting for the hours of treatment. However, the proportion of patients able to discontinue NSAIDs owing to elimination or reduction of pain was greater in the active group than in the control group. We interpret these findings as suggesting capacitive coupling electrical stimulation controls pain in some patients and reduces the use of NSAIDs. Level of Evidence: Level I, therapeutic study.

    Perception is seen as a process that utilises partial and noisy information to construct a coherent understanding of the world. Here we argue that the experience of pain is no different; it is based on incomplete, multimodal information, which is used to estimate potential bodily threat. We outline a Bayesian inference model, incorporating the key components of cue combination, causal inference, and temporal integration, which highlights the statistical problems in everyday perception. It is from this platform that we are able to review the pain literature, providing evidence from experimental, acute, and persistent phenomena to demonstrate the advantages of adopting a statistical account in pain. Our probabilistic conceptualisation suggests a principles-based view of pain, explaining a broad range of experimental and clinical findings and making testable predictions. PMID:28081134

    2003-10-01

    For chronic pain patients, acceptance of a self-management approach for pain may influence success in treatment, and adopting such a perspective may be conceptualized as a stage of change model. For 65 chronic pain patients in multidisciplinary treatment programs, we examined whether pretreatment self-management stage, assessed with Pain Stage of Change Questionnaire subscales, affected improvements in outcomes, and whether changes in stage represented a therapeutic process factor. Results showed (a) low precontemplation, high contemplation, and high action attitudes at pretreatment predicted greater improvements in outcomes than the opposite pattern of attitudes; (b) pre- to midtreatment changes in precontemplation and contemplation attitudes predicted mid- to posttreatment changes in pain severity and interference, but not vice versa. Results support the usefulness of a stage model in conceptualizing patients' acquisition of a self-management approach to pain, and suggest that early-treatment progression across stages may lead to reductions in pain severity and lifestyle interference.

    Fillingim, Roger B.; King, Christopher D.; Ribeiro-Dasilva, Margarete C.; Rahim-Williams, Bridgett; Riley, Joseph L.

    2009-01-01

    Sex-related influences on pain and analgesia have become a topic of tremendous scientific and clinical interest, especially in the last 10 to 15 years. Members of our research group published reviews of this literature more than a decade ago, and the intervening time period has witnessed robust growth in research regarding sex, gender, and pain. Therefore, it seems timely to revisit this literature. Abundant evidence from recent epidemiologic studies clearly demonstrates that women are at substantially greater risk for many clinical pain conditions, and there is some suggestion that postoperative and procedural pain may be more severe among women than men. Consistent with our previous reviews, current human findings regarding sex differences in experimental pain indicate greater pain sensitivity among females compared with males for most pain modalities, including more recently implemented clinically relevant pain models such as temporal summation of pain and intramuscular injection of algesic substances. The evidence regarding sex differences in laboratory measures of endogenous pain modulation is mixed, as are findings from studies using functional brain imaging to ascertain sex differences in pain-related cerebral activation. Also inconsistent are findings regarding sex differences in responses to pharmacologic and non-pharmacologic pain treatments. The article concludes with a discussion of potential biopsychosocial mechanisms that may underlie sex differences in pain, and considerations for future research are discussed. Perspective This article reviews the recent literature regarding sex, gender, and pain. The growing body of evidence that has accumulated in the past 10 to 15 years continues to indicate substantial sex differences in clinical and experimental pain responses, and some evidence suggests that pain treatment responses may differ for women versus men.

    1985-01-01

    Low back pain is one of the most common and costly afflictions of our Society. The majority of adults will have at least one episode of acute low back pain that will likely resolve regardless of treatment. Lumbar spine radiographs are overused and there is little scientific support for many of the therapeutic interventions advocated. Even for those patients with symptomatic herniated disc, only a small fraction will ultimately require surgical intervention. PMID:2930949

  16. Low back pain (acute)

    PubMed Central

    2011-01-01

    Introduction Low back pain affects about 70% of people in resource-rich countries at some point in their lives. Acute low back pain can be self-limiting; however, 1 year after an initial episode, as many as 33% of people still have moderate-intensity pain and 15% have severe pain. Acute low back pain has a high recurrence rate; 75% of those with a first episode have a recurrence. Although acute episodes may resolve completely, they may increase in severity and duration over time. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of oral drug treatments for acute low back pain? What are the effects of local injections for acute low back pain? What are the effects of non-drug treatments for acute low back pain? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 49 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, advice to stay active, analgesics (paracetamol, opioids), back exercises, back schools, bed rest, behavioural therapy, electromyographic biofeedback, epidural corticosteroid injections, lumbar supports, massage, multidisciplinary treatment programmes, muscle relaxants, non-steroidal anti-inflammatory drugs (NSAIDs), spinal manipulation, temperature treatments (short-wave diathermy, ultrasound, ice, heat), traction, and transcutaneous electrical nerve stimulation

    Neuropathic pain can result from neuronal hyperexcitability and complex interactions of the nociceptive pathways. Intraepidermal electrical stimulation (IES) is a novel technique that can selectively activate Aδ and C fibers. To investigate patterns of changes in Aδ- and C-mediated brain responses in patients with neuropathic pain using IES, we recorded pain-related evoked potential (PREP) after IES of Aδ and C fibers in 20 patients with neuropathic pain and 15 age-matched healthy volunteers. We evaluated PREP latencies, amplitudes, and amplitude ratios of PREPs after C/Aδ-fiber stimulation. PREP amplitudes after Aδ-fiber stimulation tended to be smaller in the patient group, whereas there were no significant differences in amplitudes after C-fiber stimulation between the patient and normal control groups. PREP amplitude ratios after C/Aδ-fiber stimulation were significantly greater in the patient group than in the control group, and the higher ratio tended to be associated with a greater visual analog scale score. Patients with neuropathic pain had a tendency towards decreased Aδ amplitudes and significantly increased C/Aδ PREP amplitude ratios and this ratio appeared to be associated with the intensity of pain. Our findings suggest that decreased inhibition of the Aδ to C nociceptive systems is associated with generation of neuropathic pain.

    The sacroiliac joint accounts for approximately 16% to 30% of cases of chronic mechanical low back pain. Pain originating in the sacroiliac joint is predominantly perceived in the gluteal region, although pain is often referred into the lower and upper lumbar region, groin, abdomen, and/ or lower limb(s). Because sacroiliac joint pain is difficult to distinguish from other forms of low back pain based on history, different provocative maneuvers have been advocated. Individually, they have weak predictive value, but combined batteries of tests can help ascertain a diagnosis. Radiological imaging is important to exclude "red flags" but contributes little in the diagnosis. Diagnostic blocks are the diagnostic gold standard but must be interpreted with caution, because false-positive as well as false-negative results occur frequently. Treatment of sacroiliac joint pain is best performed in the context of a multidisciplinary approach. Conservative treatments address the underlying causes (posture and gait disturbances) and consist of exercise therapy and manipulation. Intra-articular sacroiliac joint infiltrations with local anesthetic and corticosteroids hold the highest evidence rating (1 B+). If the latter fail or produce only short-term effects, cooled radiofrequency treatment of the lateral branches of S1 to S3 (S4) is recommended (2 B+) if available. When this procedure cannot be used, (pulsed) radiofrequency procedures targeted at L5 dorsal ramus and lateral branches of S1 to S3 may be considered (2 C+).

    Nociception is the process of transmission of painful signals by nociceptors in the primary afferent nerve fibers, which specifically respond to noxious stimuli. These noxious stimuli are detected by nociceptors and converted into electrical signals, which are then transmitted to the spinal cord, thalamus, and the cerebral cortex, where pain is finally sensed. Transient receptor potential (TRP) ion channels have emerged as a family of evolutionarily conserved ligand-gated ion channels that function as molecular detectors of physical stimuli. Several member of this family, at least six channels from three TRP family subtypes (TRPV1-4, TRPM8, and TRPA1), are expressed in nociceptors, where they act as transducers for signals from thermal, chemical, and mechanical stimuli and play crucial roles in the generation and development of pathological pain perception. This review focuses on the increasing evidence of TRP channel involvement and contribution in nociceptive pain and the pain hypersensitivity associated with peripheral inflammation or neuropathy, and on the renewed interest in targeting TRP channels for pain relief.

  1. Mechanisms of Myofascial Pain

    Myofascial pain syndrome is an important health problem. It affects a majority of the general population, impairs mobility, causes pain, and reduces the overall sense of well-being. Underlying this syndrome is the existence of painful taut bands of muscle that contain discrete, hypersensitive foci called myofascial trigger points. In spite of the significant impact on public health, a clear mechanistic understanding of the disorder does not exist. This is likely due to the complex nature of the disorder which involves the integration of cellular signaling, excitation-contraction coupling, neuromuscular inputs, local circulation, and energy metabolism. The difficulties are further exacerbated by the lack of an animal model for myofascial pain to test mechanistic hypothesis. In this review, current theories for myofascial pain are presented and their relative strengths and weaknesses are discussed. Based on new findings linking mechanoactivation of reactive oxygen species signaling to destabilized calcium signaling, we put forth a novel mechanistic hypothesis for the initiation and maintenance of myofascial trigger points. It is hoped that this lays a new foundation for understanding myofascial pain syndrome and how current therapies work, and gives key insights that will lead to the improvement of therapies for its treatment.

    The aim of the study was to determine the most effective dose of Ibuprofen - one of the non-steroidal anti-inflammatory drugs frequently used in dental practice for pain management. According to our observations, Ibuprofen markedly softens and quickly reduces procedural pain in 55 (91.67%) patients and post-procedural pain in 44 (73.33%) patients, reduces the post-procedural need for or the amount of the drug, removes the fear of anesthesia and endodontic treatment; with irreversible pulpits significantly increases the efficiency of the inferior alveolar nerve block by local anesthetics. Our clinical observation of taking ibuprofen pre-procedurally demonstrates its effectiveness not only as a means for the relief of pain episodes, but also as an excellent anti-inflammatory treatment for chronic toothache Based on our research, the appointment of non-steroidal anti-inflammatory drugs before dental interventions, in this case - Ibuprofen turned out to be the key to the success of effective pain management. We suggest that administration of analgesics in order to relieve and effectively pre-empt pain before, during or after treatment should start before surgery and furthermore, this treatment should be extended into the postoperative period. Premedication with ibuprofen significantly increased the success rates of inferior alveolar nerve block anesthesia in teeth with irreversible pulpitis.

    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).

    The lateral aspect of the hip is composed of a complex array of osseous and soft tissue structures. Both common and uncommon clinical entities are encountered in the lateral hip. This article briefly introduces fundamental imaging anatomy and the functional roles of different osseous and soft tissue structures in the lateral aspect of the hip, followed by a discussion of relevant imaging findings of lateral hip pathology. Greater trochanteric pain syndrome is frequently encountered in patients with lateral hip pain and encompasses a spectrum of soft tissue abnormalities including trochanteric and subgluteal bursitis, and tendinopathy or tears of the gluteal tendons. In addition, different types of injuries to the gluteal myotendinous unit and injuries to the indirect head of the rectus femoris, proximal iliotibial band, and the lateral joint capsular ligaments can present with lateral hip pain. Some of the less common soft tissue abnormalities of the lateral hip include Morel-Lavallée lesion and meralgia paresthetica.

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

    Best current estimates of neuropathic pain prevalence come from studies using screening tools detecting pain with probable neuropathic features; the proportion experiencing significant, long-term neuropathic pain, and the proportion not responding to standard treatment are unknown. These "refractory" cases are the most clinically important to detect, being the most severe, requiring specialist treatment. The aim of this study was to estimate the proportion of neuropathic pain in the population that is "refractory," and to quantify associated clinical and demographic features. We posted self-administered questionnaires to 10,000 adult patients randomly selected from 10 general practitioner practices in 5 UK locations. The questionnaire contained chronic pain identification and severity questions, cause of pain, SF-12, EQ-5D, S-LANSS (Self-administered Leeds Assessment of Neuropathic Signs and Symptoms), PSEQ (Pain Self-Efficacy Questionnaire), use of neuropathic pain medications, and health care utilisation. These data were combined to determine the presence and characteristics of "refractory" neuropathic pain according to the defining features identified by a Delphi survey of international experts. Graded categories of chronic pain with and without neuropathic characteristics were generated, incorporating the refractory criteria. Completed questionnaires were returned by 4451 individuals (response rate 47%); 399 had "chronic pain with neuropathic characteristics" (S-LANSS positive, 8.9% of the study sample); 215 (53.9%) also reported a positive relevant history ("Possible neuropathic pain"); and 98 (4.5% of all Chronic Pain) also reported an "adequate" trial of at least one neuropathic pain drug ("Treated possible neuropathic pain"). The most refractory cases were associated with dramatically poorer physical and mental health, lower pain self-efficacy, higher pain intensity and pain-related disability, and greater health care service use.

    The aim of this study was to investigate the influence of non-pain-related failure experiences and pain-related fear on pain report, pain tolerance and pain avoidance in chronic low back pain (CLBP) patients. Moreover, the mediating and moderating role of negative affectivity (trait-NA) in the relationship between failure experiences and pain was examined. Seventy-six patients were divided into high and low pain-related fear groups and within each group they were randomly assigned to the failure or success feedback condition. In the first part of the study patients completed a 'social empathy test' and experimenter 1 subsequently delivered false failure or success feedback. A second experimenter, who was blind for the condition, subsequently administered two lifting tasks in order to obtain measures of pain report, tolerance and avoidance. Failure feedback did have an effect on pain avoidance but unexpectedly, and not as hypothesized, pain avoidance was reduced instead of enhanced. With regard to pain report and pain tolerance similar patterns were found, but these were not statistically significant. The effect of failure feedback on pain avoidance was moderated by trait-NA. Only in the subgroup of patients who scored low on trait-NA did failure feedback decrease pain avoidance. State-NA did not mediate the effects of feedback. In line with previous findings, pain-related fear resulted in lower pain tolerance. Moreover, this study was the first to show that pain-related fear predicted higher pain report in CLBP patients. Pain-related fear did not predict pain avoidance when pre-lifting pain and gender were controlled for. Finally, pre-lifting pain turned out to be the strongest predictor with regard to all pain measures. The role of pain-related fear and unexpected findings with regard to feedback are discussed as well as some clinical implications.

    Cancer pain is multifactorial and complex. The impact of cancer pain is devastating, with increased morbidity and poor quality of life, if not treated adequately. Cancer pain management is a challenging task both due to disease process as well as a consequence of treatment-related side-effects. Optimization of analgesia with oral opioids, adjuvant analgesics, and advanced pain management techniques is the key to success for cancer pain. Early access of oral opioid and interventional pain management techniques can overcome the barriers of cancer pain, with improved quality of life. With timely and proper anticancer therapy, opioids, nerve blocks, and other non-invasive techniques like psychosocial care, satisfactory pain relief can be achieved in most of the patients. Although the WHO Analgesic Ladder is effective for more than 80% cancer pain, addition of appropriate adjuvant drugs along with early intervention is needed for improved Quality of Life. Effective cancer pain treatment requires a holistic approach with timely assessment, measurement of pain, pathophysiology involved in causing particular type of pain, and understanding of drugs to relieve pain with timely inclusion of intervention. Careful evaluation of psychosocial and mental components with good communication is necessary. Barriers to cancer pain management should be overcome with an interdisciplinary approach aiming to provide adequate analgesia with minimal side-effects. Management of cancer pain should comprise not only a physical component but also psychosocial and mental components and social need of the patient. With risk–benefit analysis, interventional techniques should be included in an early stage of pain treatment. This article summarizes the need for early and effective pain management strategies, awareness regarding pain control, and barriers of cancer pain. PMID:21976852

    Pain management is vitally important to injured patients being evacuated from the warzone. A prospective assessment of real-time ratings of pain acceptability, intensity, and satisfaction of a convenience sample of 114 less severely ill and injured U.S. military patients being evacuated on Aeromedical Evacuation (AE) missions from Ramstein Air Field, Germany, to Andrews Air Force Base, Maryland, was conducted. Data were collected before and during 12 AE flights in December 2012 and May 2013. Acceptable pain intensity was a median of 6/10 (range 2-9), with 76% of patients indicating an acceptable pain intensity greater than 4. During AE transport, 75% of patients reported at least one pain score≥4. Despite these high pain ratings, there was documentation of administration for only 58% of routine and 48% for as-needed analgesics/adjuvants. Over 47% of patients experienced pain that exceeded their acceptable intensity level, but of those patients with pain that was more severe than acceptable, only 10% rated their satisfaction with their pain management as poor or fair. This is the first study to provide real-time concurrent assessment of pain and pain management during en route care. The worst pain was reported for the hospital to aircraft arrival, suggesting the need for interventions to safely optimize pain management during this handoff period.

    We examined whether pain outcomes (pain interference, perceived pain treatment effectiveness) vary by race and then whether opioid use moderates these associations. These analyses are part of a retrospective cohort study among 3,505 black and 46,203 non-Hispanic, white Department of Veterans Affairs (VA) patients with diagnoses of chronic musculoskeletal pain who responded to the 2007 VA Survey of Healthcare Experiences of Patients (SHEP). We used electronic medical record data to identify prescriptions for pharmacologic pain treatments in the year after diagnosis (Pain Diagnosis index visit) and before the SHEP index visit (the visit that made one eligible to complete the SHEP); pain outcomes came from the SHEP. We found no significant associations between race and pain interference or perceived effectiveness of pain treatment. VA patients with opioid prescriptions between the Pain Diagnosis index visit and the SHEP index visit reported greater pain interference on the SHEP than those without opioid prescriptions during that period. Opioid prescriptions were not associated with perceived treatment effectiveness for most patients. Findings raise questions about benefits of opioids for musculoskeletal pain and point to the need for alternative treatments for addressing chronic noncancer pain.

    Persistent or chronic pain is tightly associated with various environmental changes and linked to abnormal gene expression within cells processing nociceptive signaling. Epigenetic regulation governs gene expression in response to environmental cues. Recent animal model and clinical studies indicate that epigenetic regulation plays an important role in the development/maintenance of persistent pain and, possibly the transition of acute pain to chronic pain, thus shedding light in a direction for development of new therapeutics for persistent pain.

    Evidence suggests that patients with irritable bowel syndrome (IBS) are more vigilant to pain-associated stimuli. The aims of this study were to compare women with IBS (n = 20) to healthy control (HC, n = 20) women on pain sensitivity, conditioned pain modulation (CPM) efficiency and salivary cortisol levels before and after the CPM test; and examine the relationship of CPM efficiency with gastrointestinal, somatic pain, and psychological distress symptoms in each group. Women, ages 20–42, gave consent, completed questionnaires and kept a symptom diary for 2 weeks. CPM efficiency was tested with a heat test stimulus and cold water condition stimulus in a laboratory between 8 and 10 a.m. on a follicular phase day. Salivary cortisol samples were collected just before and after the experimental testing. Compared to the HC group, women with IBS reported more days with gastrointestinal and somatic pain/discomfort, psychological distress, fatigue, and feeling stressed. During the CPM baseline testing women with IBS reported greater pain sensitivity compared to the HC group. In the IBS group, CPM efficiency was associated with the pain impact (PROMIS) measure, daily abdominal pain/discomfort, psychological distress, in particular anxiety. There was no group difference in salivary cortisol levels. Overall, women with IBS exhibit an increased sensitivity to thermal stimuli. Impaired CPM was present in a subset of women with IBS.

    Objectives: The present study was designed to evaluate the usefulness of deep dry needling in the treatment of temporomandibular myofascial pain. Study Design: We selected 36 patients with myofascial pain located in the external pterygoid muscle (30 women/6 men, mean age=27 years with SD±6,5). We studied differences in pain with a visual analog scale and range of mandibular movements before and after intervention. Results: We found a statistically significant relationship (p<0,01) between therapeutic intervention and the improvement of pain and jaw movements, which continued up to 6 months after treatment. Pain reduction was greater the higher was the intensity of pain at baseline. Conclusions: Although further studies are needed, our findings suggest that deep dry needling in the trigger point in the external pterygoid muscle can be effective in the management of patients with myofascial pain located in that muscle. Key words:Temporomandibular joint, myofascial pain, external pterygoid muscle, trigger point, deep dry needling. PMID:22549679

    Introduction: Spinal pain in the paediatric population is a significant health issue, with an increasing prevalence as they age. Paediatric patients attend for chiropractor care for spinal pain, yet, there is a paucity of quality evidence to guide the practitioner with respect to appropriate care planning. Methods: A retrospective chart review was used to describe chiropractic management of paediatric neck pain. Two researchers abstracted data from 50 clinical files that met inclusion criteria from a general practice chiropractic office in the Greater Toronto Area, Canada. Data were entered into SPSS 15 and descriptively analyzed. Results: Fifty paediatric neck pain patient files were analysed. Patients’ age ranged between 6 and 18 years (mean 13 years). Most (98%) were diagnosed with Grade I–II mechanical neck pain. Treatment frequency averaged 5 visits over 19 days; with spinal manipulative therapy used in 96% of patients. Significant improvement was recorded in 96% of the files. No adverse events were documented. Conclusion: Paediatric mechanical neck pain appears to be successfully managed by chiropractic care. Spinal manipulative therapy appears to benefit paediatric mechanical neck pain resulting from day-today activities with no reported serious adverse events. Results can be used to inform clinical trials assessing effectiveness of manual therapy in managing paediatric mechanical neck pain. PMID:27713576

    The objective of this paper is to test and correct for systematic differences in reporting of pain severity among older adults by age, gender, ethnic group and socio-economic status using anchoring vignettes. Data from a national survey of community-dwelling older Singaporeans (aged 60 years and over) conducted in 2009 was used. Respondents were asked to rate the severity of their own pain as well as that of others described in the vignettes on a five-point scale ranging from none to extreme. An ordered probit model was used to estimate the coefficients of the independent variables (age, gender, ethnic group, education, housing type) on self-reported pain. Reporting heterogeneity in pain severity was then corrected using a Hierarchical Ordered Probit model. The results showed that before correcting for reporting heterogeneity, women, those older, and those of Malay ethnicity reported greater severity of pain, while there was no association of reported pain severity with housing type and education. However, after correcting for reporting heterogeneity, while women and those older were found to have an even greater severity of pain than what they had reported, Malays were found to have a lower severity of pain than what they had reported. We conclude that there are systematic differences in reporting pain severity by age, gender and ethnic group. We propose that pain management may be improved if medical professionals take into account reporting heterogeneity for pain severity among various population sub-groups in Singapore.

    Purpose: Back pain is the leading cause of global years lived with disability. This cross-sectional study assessed if a greater exposure to smoking cigarettes was associated with a greater prevalence of back pain. Methods: This study examined data from 34,525 United States adults from the 2012 National Health Interview Survey. Analyses assessed the difference in back pain prevalence among current smokers, former smokers, and never smokers and the number of cigarettes smoked between current smokers with and without back pain. Results: Back pain prevalence was 28%. There was a significant association between back pain and smoking, X2 (2, 599, n = 34, 241) = 546.3, p < .001. Back pain increased with increased smoking exposure; back pain was present in 23.5% of never-smokers, 33.1% of former smokers, and 36.9% of current smokers. The number of cigarettes smoked per day for current daily smokers was higher for those with back pain (Md = 13) than those without back pain (Md = 10), U = 2701065, z = -3.70, p < .001, r = .05. Conclusions: Our findings suggest that there may be a biological gradient associated with exposure to smoking cigarettes and back pain in adult Americans. PMID:27790393

    2009-01-01

    Neuropathic pain is one of the worst painful symptoms in clinic. It contains nerve-injured neuropathy, diabetic neuropathy, chronic inflammatory pain, cancer pain, and postherpes pain, and is characterized by a tactile allodynia and hyperalgesia. Neuropathic pain, especially the nerve-injured neuropathy, the diabetic neuropathy, and the cancer pain, is opioid resistant pain. Since the downregulation of mu-opioid receptors is observed in dorsal spinal cord, morphine and fentanyl could not provide marked antihyperalgesic/antiallodynic effects in the course neuropathic pain states. The downregulation of mu-opioid receptors is suggested to be mediated through the activation of NMDA receptors. Moreover, at the neuropathic pain states, the increased expression of voltage-dependent Na+ channels and Ca2+ channels are observed. Based on the above information concerned with the pathophysiology of neural changes in neuropathic pain states, new drug treatments for neuropathic pain, using ketamine, methadone, and gabapentin, have been developed. These drugs show remarkable effectiveness against hyperalgesia and allodynia during neuropathic pain states. Oxycodone is a mu-opioid receptor agonist, which has different pharmacological profiles with morphine. The remarkable effectiveness of oxycodone for neuropathic pain provides the possibility that mu-opioid receptor agonists, which have different pharmacological profile with morphine, can be used for the management of neuropathic pain.

    Greater dispositional optimism has been related to less severe pain; however, whether optimism is associated with endogenous pain modulation has not yet been examined. The beneficial effects of dispositional optimism often vary according to cultural dynamics. Thus, assessing optimism-pain relationships across different ethnic groups is warranted. This study sought to examine the association between optimism and conditioned pain modulation (CPM), and test whether this association differs according to ethnicity. Optimism and CPM were assessed in a sample of healthy, ethnically diverse young adults. CPM was determined by comparing pressure pain thresholds obtained before and during exposure to a cold pressor task. All participants completed a validated measure of dispositional optimism. Greater reported optimism was significantly associated with enhanced CPM, and the strength of this association did not vary according to individuals’ ethnic background. These findings suggest that an optimistic disposition may potentiate endogenous pain inhibition. PMID:22367226

    Purpose: Pain is a common symptom among cancer patients, yet many patients do not receive adequate pain management. Few data exist quantifying analgesic use by radiation oncology patients. This study evaluated the causes of pain in cancer patients and investigated the reasons patients fail to receive optimal analgesic therapy. Methods and Materials: An institutional review board-approved, Internet-based questionnaire assessing analgesic use and pain control was posted on the OncoLink (available at (www.oncolink.org)) Website. Between November 2005 and April 2006, 243 patients responded. They were predominantly women (73%), white (71%), and educated beyond high school (67%) and had breast (38%), lung (6%), or ovarian (6%) cancer. This analysis evaluated the 106 patients (44%) who underwent radiotherapy. Results: Of the 106 patients, 58% reported pain from their cancer treatment, and 46% reported pain directly from their cancer. The pain was chronic in 51% and intermittent in 33%. Most (80%) did not use medication to manage their pain. Analgesic use was significantly less in patients with greater education levels (11% vs. 36%, p = 0.002), with a trend toward lower use by whites (16% vs. 32%, p 0.082) and women (17% vs. 29%, p = 0.178). The reasons for not taking analgesics included healthcare provider not recommending medication (87%), fear of addiction or dependence (79%), and inability to pay (79%). Participants experiencing pain, but not taking analgesics, pursued alternative therapies for relief. Conclusions: Many radiation oncology patients experience pain from their disease and cancer treatment. Most study participants did not use analgesics because of concerns of addiction, cost, or failure of the radiation oncologist to recommend medication. Healthcare providers should have open discussions with their patients regarding pain symptoms and treatment.

    Background Despite providing insufficient medical evidence of the existence of a real cardiac condition, patients with non-coronary chest pain still interpret their pain incorrectly. The present study, therefore, sought to compare the irrational beliefs in non-coronary patients with mild chest pain against those with severe chest pain. Methods A cross-sectional design was used. The statistical population comprised non-coronary patients who presented to the Heart Emergency Center of Kermanshah city, Iran. Using a matching method, 96 participants were selected and studied in two groups of 48. The instruments used were the Comorbidity Index, Brief Pain Index, and the Jones Irrational Beliefs Test (short-form). The multivariate analysis of variance, chi-square test, and t-test were used for data analysis. Results Controlling for the effects of age and comorbid conditions, the severity of three types of irrational beliefs, including emotional irresponsibility (P<0.001), hopelessness changes (P<0.001), and problem avoiding (P=0.002) was higher among patients with severe chest pain (according to effect level). However, in terms of demand for approval, no difference was seen between the two groups (P=0.180). Conclusion Non-coronary patients with severe chest pain showed a greater number of irrational beliefs in comparison to patients with mild pain. Irrational beliefs are common mental occurrences in patients with non-coronary chest pain, and they should be attended to by health professionals, especially in severe non-coronary chest pain. Further investigation to determine the association between irrational beliefs and non-coronary chest pain is necessary. PMID:26217482

    Chronic widespread pain is associated with several medical and psychiatric disorders including, but not limited to, chronic fatigue syndrome, fibromyalgia, mood disorders, hepatitis, endocrine disorders such as hypothyroidism, and rheumatologic disorders such as rheumatoid arthritis. Careful and comprehensive differential diagnosis must be performed to ensure a correct diagnosis before an appropriate treatment can be selected. Fibromyalgia, in particular, is challenging to diagnose and treat because it shares many characteristics with other disorders and is commonly concurrent with major mood disorders. A comprehensive disease management strategy including patient education, pharmacotherapy, cognitive-behavioral therapy, and aerobic and other forms of exercise can be beneficial for many patients with fibromyalgia.

    The nociceptive system enables us to respond in time to external threats that otherwise would produce tissue damage. By monitoring tissue composition the system also contributes to bodily homeostasis. Nociceptors signal mechanical stress, extreme temperatures, cell injury and inflammation. Powerful modulation of nociceptive signals occurs in the spinal dorsal horn, so that their further transmission to the brain can be enhanced or inhibited. A vast array of transmitters and receptors are responsible for complex synaptic interactions in the dorsal horn. Synaptic plasticity alters neuronal excitability for hours to months (years?), contributing to hyperalgesia and chronic pain. Descending monoaminergic connections from the brain stem can inhibit or facilitate the signal transmission from nociceptors. These systems are partly controlled by ascending signals from the dorsal horn, partly by descending connections from amygdala, hypothalamus and the cerebral cortex. The latter are thought to contribute to context-dependent pain modulation. The subjective experience of pain correlates with increased activity in a cortical network including the insula, the cingulate gyrus and some other areas. The activity of the network is also positively correlated with expectation of pain, and negatively correlated with expectation of pain relief--independent of nociceptor stimulation.

    As the biological alarm of impending or actual tissue damage, pain is essential for our survival. However, when it is initiated and/or sustained by dysfunctional elements in the nociceptive system, it is itself a disease known as neuropathic pain. While the critical nociceptive system provides a number of protective functions, it is unique in its central role of monitoring, preserving and restoring the optical tear film in the face of evaporative attrition without which our vision would be non-functional. Meeting this existential need resulted in the evolution of the highly complex, powerful and sensitive dry eye alarm system integrated in the peripheral and central trigeminal sensory network. The clinical consequences of corneal damage to these nociceptive pathways are determined by the type and location of its pathological elements and can range from the spectrum known as dry eye disease to the centalised oculofacial neuropathic pain syndrome characterised by a striking disparity between the high intensity of symptoms and paucity of external signs. These changes parallel those observed in somatic neuropathic pain. When seen through the neuroscience lens, diseases responsible for inadequately explained chronic eye pain (including those described as dry eye) can take on new meanings that may clarify long-standing enigmas and point to new approaches for developing preventive, symptomatic and disease-modifying interventions for these currently refractory disorders.

  7. Functional abdominal pain

    2005-01-01

    Functional abdominal pain or functional abdominal pain syndrome (FAPS) is an uncommon functional gut disorder characterised by chronic or recurrent abdominal pain attributed to the gut but poorly related to gut function. It is associated with abnormal illness behaviour and patients show psychological morbidity that is often minimised or denied in an attempt to discover an organic cause for symptoms. Thus the conventional biomedical approach to the management of such patients is unhelpful and a person's symptom experience is more usefully investigated using a biopsychosocial evaluation, which necessarily entails a multidisciplinary system of healthcare provision. Currently the pathophysiology of the disorder is poorly understood but is most likely to involve a dysfunction of central pain mechanisms either in terms of attentional bias, for example, hypervigilance or a failure of central pain modulation/inhibition. Although modern neurophysiological investigation of patients is promising and may provide important insights into the pathophysiology of FAPS, current clinical management relies on an effective physician-patient relationship in which limits on clinical investigation are set and achievable treatment goals tailored to the patient's needs are pursued.

    Psychosomatics of visceral pain syndromes. From a psychosomatic point of view visceral pain syndromes can be classified into nociceptive (somatic and visceral) pain syndromes without and with maladaptive pain coping resp.psychic comorbidity, functional pain syndromes (typical symptom clusters without biochemical or structural abnormalities in clinical routine diagnostics) and psychic disorders with pain as main symptom. With regard to the etiology and the course of chronic inflammatory bowel diseases (IBD) as representatives of somatic pain syndromes and of irritable bowel syndrome/chronic pelvic pain as representatives of functional pain syndromes empirically validated psychosocial aspects are summarized: Personality traits, illness behavior, daily hassles, life events and psychic comorbidity and effects of psychotherapy. Psychosocial factors are decisive in the etiology and the course of functional pain syndromes as determinants of their severity (psychosomatic disease in a narrow sense). Psychosocial factors are not decisive for the etiology, but for the course of IBD (psychosomatic disease in a broader sense). Within general pain therapy of visceral pain syndromes a biopsychosocial approach should be applied right from the beginning (psychosomatic basic care). Within special pain therapy of visceral pain syndromes a qualified psychiatric - psychotherapeutic diagnostics and co-therapy should be mandatory.

  9. Diagnosing heel pain in adults.

    PubMed

    Aldridge, Tracy

    2004-07-15

    Heel pain is a common condition in adults that may cause significant discomfort and disability. A variety of soft tissue, osseous, and systemic disorders can cause heel pain. Narrowing the differential diagnosis begins with a history and physical examination of the lower extremity to pinpoint the anatomic origin of the heel pain. The most common cause of heel pain in adults is plantar fasciitis. Patients with plantar fasciitis report increased heel pain with their first steps in the morning or when they stand up after prolonged sitting. Tenderness at the calcaneal tuberosity usually is apparent on examination and is increased with passive dorsiflexion of the toes. Tendonitis also may cause heel pain. Achilles tendonitis is associated with posterior heel pain. Bursae adjacent to the Achilles tendon insertion may become inflamed and cause pain. Calcaneal stress fractures are more likely to occur in athletes who participate in sports that require running and jumping. Patients with plantar heel pain accompanied by tingling, burning, or numbness may have tarsal tunnel syndrome. Heel pad atrophy may present with diffuse plantar heel pain, especially in patients who are older and obese. Less common causes of heel pain, which should be considered when symptoms are prolonged or unexplained, include osteomyelitis, bony abnormalities (such as calcaneal stress fracture), or tumor. Heel pain rarely is a presenting symptom in patients with systemic illnesses, but the latter may be a factor in persons with bilateral heel pain, pain in other joints, or known inflammatory arthritis conditions.

    The objective of this study was to determine if the combination of tenderness-guided endovaginal ultrasound and digital pelvic exam (i.e. EVUS-assisted exam) for preoperative pain mapping, in cases without nodules or endometriomas, increases sensitivity/specificity for laparoscopic findings. This was a retrospective review of women with chronic pelvic pain ± infertility with preoperative pain mapping exam prior to laparoscopy (n = 97, 2006-7). Predictor variables (EVUS-assisted exam vs digital pelvic exam alone, for pain mapping) were coded as tender vs non-tender. Primary outcome was findings on laparoscopy (e.g. endometriosis or adhesions) and was coded as abnormal vs normal. We found that EVUS-assisted exam had greater sensitivity (0.81, 95% CI: 0.70-0.89) for abnormal laparoscopy compared with digital pelvic exam alone (0.58, 95% CI: 0.46-0.69) (McNemar's test, p < 0.001). Specificity was limited for both types of pain mapping (0.22, 95% CI: 0.08-0.44 for EVUS-assisted; and 0.39, 95% CI: 0.20-0.61 for digital), with no significant difference (p = 0.13). In conclusion, in the absence of nodules or endometriomas, EVUS-assisted exam increases sensitivity, but with no benefit in specificity, for prediction of abnormal laparoscopy.

  11. Striatal opioid receptor availability is related to acute and chronic pain perception in arthritis: does opioid adaptation increase resilience to chronic pain?

    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.

    Pain characteristics, muscle function and impact on daily activities were studied in 39 women with chronic regional muscular pain (RMP). They were all blue-collar workers in work involving precise manipulations. The main location of the pain was in the neck-shoulder region. Nineteen age-matched women with fibromyalgia (FM) were studied in the same way as the RMP patients. Thirty-seven women with no pain and with the same age and weight as the RMP patients served as reference group with respect to muscle strength and endurance. A follow-up study was done with respect to pain distribution and other pain characteristics 20 months after the initial examination. The findings were of the same nature in the RMP and the FM groups. The intensity of pain, the lowering of pain threshold for pressure, and the degree of sleep disturbance were greater in the FM than in the RMP group. Isometric muscle strength and static muscular endurance were reduced in both FM and RMP compared to reference values. The reduction in strength and endurance was greater in FM than in RMP. Even if the impact on everyday activities were greater in FM than in RMP, the impact was substantial in RMP patients also, for example with regard to work capacity. There were no transitions from RMP to FM during the 20 months to follow-up. Three FM patients, however, did not meet the ACR criteria for FM at follow-up.

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

    Recent reports suggest deficits in conditioned pain modulation (CPM) and enhanced suprathreshold heat pain response (SHPR) potentially play a role in the development of chronic pain. The purpose of this study was to investigate whether central pain processing was altered in 2 musculoskeletal shoulder pain models. The goals of this study were to determine whether central pain processing: 1) differs between healthy subjects and patients with clinical shoulder pain, 2) changes with induction of exercise induced muscle pain (EIMP), and 3) changes 3 months after shoulder surgery. Fifty eight patients with clinical shoulder pain and 56 age and sex matched healthy subjects were included in these analyses. The healthy cohort was examined before inducing EIMP, and 48 and 96 hours later. The clinical cohort was examined before shoulder surgery and 3 months later. CPM did not differ between the cohorts, however; SHPR was elevated for patients with shoulder pain compared to healthy controls. Induction of acute shoulder pain with EIMP resulted in increased shoulder pain intensity but did not change CPM or SHPR. Three months following shoulder surgery clinical pain intensity decreased but CPM was unchanged from pre-operative assessment. In contrast SHPR was decreased and showed values comparable with healthy controls at 3 months. Therefore, the present study suggests that: 1) clinical shoulder pain is associated with measurable changes in central pain processing, 2) exercise-induced shoulder pain did not affect measures of central pain processing, and 3) elevated SHPR was normalized with shoulder surgery. Collectively our findings support neuroplastic changes in pain modulation were associated with decreases in clinical pain intensity only, and could be detected more readily with thermal stimuli.

    The studies reviewed here show that the duration and severity of individual episodes of back pain can be lessened, reducing recurrences and their cost in terms of suffering and lost work. Frank examines differential diagnosis; acute, chronic, and intractable pain; and service implications. Modern management emphasises self care, and bed rest should usually not be longer than 48 hours. A return to physical fitness and other activities, including employment, is actively encouraged. Medication has a role in facilitating these objectives. Two points are especially emphasised: strategies to manage low back pain must be long term and preventive; and the responsibility to keep fit, maintain an exercise programme, and remain relaxed so as to avoid physically stressing the spine is that of the individual, not of the professionals.

    The self is not a unitary concept but has different facets, encompassing potentially contradictory states, intentions or desires. The ensuing contradictory facets of the self lead to internal discrepancies which can have both motivational and emotional consequences. Self-Discrepancy Theory (SDT) explains emotional consequences by considering discrepancies between the actual, ideal or ought self. Depression can be part predicted by considering the extent an individual regards their self as enmeshed with their pain. Individuals who place a high value on independence or social interaction are more likely to experience a high anxious state in the presence of the “mere threat” of pain enmeshment. Consequently pain can rapidly come to infiltrate and affect a person's sense of self. PMID:26527455

    1994-12-01

    This report summarizes research on the hypothesis that idiopathic chronic pain syndromes and depressive disorders share certain common pathogenetic mechanisms. There is increasing evidence that this may be partly true. Not only do chronic pain syndromes respond to treatment with antidepressants, but there are also striking clinical similarities between these syndromes and depressive syndromes. However, important differences do exist (e.g., the courses of these disorders are usually dissimilar). Family studies show that affective disorders are common in first-degree relatives of patients with idiopathic pain syndromes, but it is impossible to conclude from this that clear-cut genetic factors are of importance. Factors common to both syndromes include common personality traits, shortened rapid eye movements in sleep EEG, hypercortisolaemia and pathological dexamethasone suppression tests, low levels of melatonin in serum and urine and high levels of endorphins and Fraction I in cerebro-spinal fluid. One important common pathogenetic mechanism seems to be disturbances in the serotoninergic system.

    Background Individuals with functional gastrointestinal disorders (FGIDs) report experiencing trauma more often than healthy controls, but little is known regarding psychophysical correlates. Purpose Test the hypothesis that adolescents and young adults with FGIDs since childhood and a trauma history (n = 38) would exhibit heightened temporal summation to thermal pain stimuli, an index of central sensitization, and greater clinical symptoms compared to patients with FGIDs and no trauma history (n = 95) and healthy controls (n =135). Methods Participants completed self-report measures, an experimental pain protocol, and psychiatric diagnostic interview as part of a larger longitudinal study. Results FGID+Trauma patients exhibited greater temporal summation than FGID+No Trauma patients and healthy controls. Additionally, FGID+Trauma patients exhibited greater gastrointestinal and non-gastrointestinal symptom severity, number of chronic pain sites, and disability. Conclusions Assessing for trauma history in patients with FGIDs could identify a subset at risk for greater central sensitization and pain-related symptoms. PMID:25967582

    Pain burden is high in people living with HIV (PLWH), but the effect of this pain on functionality is equivocal. Resilience, the ability to cope with adversity, may promote adaptation to pain, so we hypothesised that higher resilience would correlate with less pain-related impairment of activity. We recruited 197 black South African PLWH, 99 with chronic pain (CP) and 98 patients without. We measured pain intensity and interference using the Brief Pain Inventory, and resilience using the Resilience Scale. Participants were generally highly resilient. Greater resilience correlated with better health-related quality of life, but not with pain intensity or interference. We also measured physical activity objectively, by actigraphy, in a subset of patients (37 with chronic pain and 31 without chronic pain), who wore accelerometers for two weeks. There was no difference in duration or intensity of activity between those with and without pain, and activity was not associated with resilience. In this sample, pain was not associated with altered physical activity. Resilience did not explain differences in pain intensity or pain interference but was associated with improved quality of life. Financial stresses and the fear of HIV stigma may have driven patients to conceal pain and to suppress its expected impairment of activity.

    Study Design Best evidence synthesis. Objective To identify, critically appraise, and synthesize literature from 1980 through 2006 on surgical interventions for neck pain alone or with radicular pain in the absence of serious pathologic disease. Summary of Background Data There have been no comprehensive systematic literature or evidence-based reviews published on this topic. Methods We systematically searched Medline for literature published from 1980 to 2006 on percutaneous and open surgical interventions for neck pain. Publications on the topic were also solicited from experts in the field. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our Best Evidence Synthesis. Results Of the 31,878 articles screened, 1203 studies were relevant to the Neck Pain Task Force mandate and of these, 31 regarding treatment by surgery or injections were accepted as scientifically admissible. Radiofrequency neurotomy, cervical facet injections, cervical fusion and cervical arthroplasty for neck pain without radiculopathy are not supported by current evidence. We found there is support for short-term symptomatic improvement of radicular symptoms with epidural corticosteroids. It is not clear from the evidence that long-term out comes are improved with the surgical treatment of cervical radiculopathy compared to non operative measures. However, relatively rapid and substantial symptomatic relief after surgical treatment seems to be reliably achieved. It is not evident that one open surgical technique is clearly superior to others for radiculopathy. Cervical foramenal or epidural injections are associated with relatively frequent minor adverse events (5%–20%); however, serious adverse events are very uncommon (<1%). After open surgical procedures on the cervical spine, potentially serious acute complications are seen in approximately 4% of patients. Conclusion Surgical treatment and limited

    Chronic orofacial pain (COFP) is an umbrella term used to describe painful regional syndromes with a chronic, unremitting pattern. This is a convenience term, similar to chronic daily headaches, but is of clinically questionable significance: syndromes that make up COFP require individually tailored diagnostic approaches and treatment. Herein we describe the three main categories of COFP: musculoskeletal, neurovascular, and neuropathic. For many years, COFP and headache have been looked upon as discrete entities. However, we propose the concept that because COFP and headaches share underlying pathophysiological mechanisms, clinical characteristics, and neurovascular anatomy, they should be classified together.

CRPS is not uncommon after hand surgery and may complicate post-operative care. There is no specific diagnostic test for CRPS and the diagnosis is based on history, clinical examination, and supportive laboratory findings. Recent modifications to diagnostic criteria have enabled clinicians to diagnose this disease more consistently.

    Training in mindfulness is a well-supported therapeutic strategy for pain conditions, though short-term mindfulness training for acute pain is not always effective. To explore the possibility that initial attempts at mindfulness in people without previous training may drain self-regulatory resources, the current study used a student sample (N=63) to test the hypothesis that brief instruction in mindfulness would lead to reduced pain tolerance on a cold pressor task (CPT), compared to more familiar strategies for coping with acute pain. We also investigated whether high heart rate variability (HRV), a physiological indicator of self-regulatory capacity, would predict pain tolerance. Higher HRV predicted greater pain tolerance only in the control group, suggesting that applying unfamiliar mindfulness strategies while attempting to tolerate pain more rapidly sapped self-regulatory strength.

    The objective of our study was to review the effectiveness of needle acupuncture in treating the common and disabling problem of pelvic and back pain in pregnancy. Two small trials on mixed pelvic/back pain and 1 large high-quality trial on pelvic pain met the inclusion criteria. Acupuncture, as an adjunct to standard treatment, was superior to standard treatment alone and physiotherapy in relieving mixed pelvic/back pain. Women with well-defined pelvic pain had greater relief of pain with a combination of acupuncture and standard treatment, compared to standard treatment alone or stabilizing exercises and standard treatment. We used a narrative synthesis due to significant clinical heterogeneity between trials. Few and minor adverse events were reported. We conclude that limited evidence supports acupuncture use in treating pregnancy-related pelvic and back pain. Additional high-quality trials are needed to test the existing promising evidence for this relatively safe and popular complementary therapy.

    Objective: To conduct a post hoc evaluation of the prevalence of clinically significant pain and the efficacy of duloxetine in patients with generalized anxiety disorder (GAD) and concurrent pain. Method: Data from two 9- to 10-week double-blind, placebo-controlled, randomized clinical trials of duloxetine (60 to 120 mg) in DSM-IV–defined GAD were analyzed (study 1 was conducted from July 2004 to September 2005; study 2 was conducted from August 2004 to June 2005). Efficacy was assessed with the Hamilton Rating Scale for Anxiety (HAM-A), visual analog scales (VAS) for pain, the Hospital Anxiety Depression Scale (HADS), the Clinical Global Impressions-Improvement of Illness (CGI-I) scale, the Patient Global Impressions-Improvement (PGI-I) scale, and the Sheehan Disability Scale (SDS) global functional impairment scale. Results: Of 840 patients randomly assigned to treatment, 61.3% (302 duloxetine, 213 placebo) had VAS scores ≥ 30 mm on at least 1 of the pain scales, indicating clinically significant pain. Among those patients with concurrent pain at baseline, change from baseline to endpoint in the HAM-A total score (42.9% change in mean scores for duloxetine, 31.4% for placebo), HADS anxiety scale (40.3% vs. 22.8%), HADS depression scale (36.1% vs. 20.5%), HAM-A psychic factor (45.9% vs. 29.9%), and SDS global functional improvement score (45.5% vs. 22.1%) was significantly (all p's < .001) greater for duloxetine compared with placebo. Improvement on the CGI-I (p = .003) and PGI-I (p < .001) was also significantly greater for duloxetine. Response (HAM-A total score decrease ≥ 50%) (49% vs. 29%) and remission (HAM-A total score ≤ 7 at endpoint) (29% vs. 18%) rates were significantly greater for duloxetine compared with placebo (p < .001 and p = .041, respectively). Duloxetine demonstrated statistically significantly greater reduction in pain on all 6 VAS pain scales (all p's < .001 except headaches with p < .002) (for duloxetine, percent change in means from

    Pain is fundamentally unpleasant, a feature that protects the organism by promoting motivation and learning. Relief of aversive states, including pain, is rewarding. The aversiveness of pain, as well as the reward from relief of pain, is encoded by brain reward/motivational mesocorticolimbic circuitry. In this Review, we describe current knowledge of the impact of acute and chronic pain on reward/motivation circuits gained from preclinical models and from human neuroimaging. We highlight emerging clinical evidence suggesting that anatomical and functional changes in these circuits contribute to the transition from acute to chronic pain. We propose that assessing activity in these conserved circuits can offer new outcome measures for preclinical evaluation of analgesic efficacy to improve translation and speed drug discovery. We further suggest that targeting reward/motivation circuits may provide a path for normalizing the consequences of chronic pain to the brain, surpassing symptomatic management to promote recovery from chronic pain.

  13. [Pain and Christianity. A symbol for overcoming pain?].

    Pain and Christianity appear to belong together: Christ's pain stands at the centre of God's healing; his pain leads to the salvation of mankind. We can learn from Jesus' example how to bear suffering and pain. In early Christian times, the belief that Jesus Christ suffered pain on the cross was usually not accepted. In line with the "apathy axiom", freedom from emotion was something to strive for at that time. Only after the acceptance of Christianity as the state religion of the Roman Empire in 380 AD did the pain of Christ again stand in the centre of the Christian doctrine of salvation. The memory of the fact that Jesus himself had to undergo the worst pain can still help people to overcome their pain and comfort them.

    Sex differences in response to experimental pain are commonly reported in systematic reviews in the adult literature. The objective of the present research was to conduct a systematic review and meta-analysis of sex differences in healthy children's responses to experimental pain (e.g., cold pressor, heat pain, pressure pain) and, where possible, to conduct analyses separately for children and adolescents. A search was conducted of electronic databases for published papers in English of empirical research using experimental pain tasks to examine pain-related outcomes in healthy boys and girls between 0 and 18 years of age. Eighty articles were eligible for inclusion and were coded to extract information relevant to sex differences. The systematic review indicated that, across different experimental pain tasks, the majority of studies reported no significant differences between boys and girls on pain-related outcomes. However, the meta-analysis of available combined data found that girls reported significantly higher cold pressor pain intensity compared to boys in studies where the mean age of participants was greater than 12 years. Additionally, a meta-analysis of heat pain found that boys had significantly higher tolerance than girls overall, and boys had significantly higher heat pain threshold than girls in studies where the mean age of participants was 12 years or younger. These findings suggest that developmental stage may be relevant for understanding sex differences in pain.

    While high levels of negative affect and cognitions have been associated in chronic pain conditions with greater pain sensitivity, the neural mechanisms mediating the hyperalgesic effect of psychological factors in patients with pain disorders are largely unknown. In this cross-sectional study, we hypothesized that 1) catastrophizing modulates brain responses to pain anticipation, and that 2) anticipatory brain activity mediates the hyperalgesic effect of different levels of catastrophizing, in fibromyalgia (FM) patients. Using functional Magnetic Resonance Imaging, we scanned the brains of 31 FM patients exposed to visual cues anticipating the onset of moderately intense deep-tissue pain stimuli. Our results indicated the existence of a negative association between catastrophizing and pain-anticipatory brain activity, including in the right lateral prefrontal cortex (IPFC). A bootstrapped mediation analysis revealed that pain-anticipatory activity in lateral prefrontal cortex (IPFC) mediates the association between catastrophizing and pain sensitivity. These findings highlight the role of IPFC in the pathophysiology of FM related hyperalgesia, and suggest that deficits in the recruitment of pain-inhibitory brain circuitry during pain-anticipatory periods may play an important contributory role in the association between various degrees of widespread hyperalgesia in FM and levels of catastrophizing, a well validated measure of negative cognitions and psychological distress. Perspective This article highlights the presence of alterations in pain-anticipatory brain activity in FM. These findings provide the rationale for the development of psychological or neurofeedback-based techniques aimed at modifying patients' negative affect and cognitions towards pain. PMID:25937162

    Objectives. To describe the rationale for the pain presence, location, and intensity measures in the National Social Life, Health and Aging Project (NSHAP). Method. Responses to the pain presence, location (pain map), and intensity (verbal descriptor scale) items were analyzed by gender and age (62–69, 70–79, and 80–91). Pain intensity was dichotomized (none to mild vs moderate or higher) and compared by demographics, physical function, mood, and self-rated health. All analyses used Wald tests to compare sample means. Results. Participants completed the pain presence (n = 2,430/2,799), location (n = 2,558/2,799), and intensity (n = 2,589/2,799) items. Pain items varied by gender with women reporting more head, arm, hip/buttock, leg, and foot pain compared to men, (p < .05) at each individual site. Women also reported more intense pain compared to men—2.13 versus 1.94, respectively (p < .05). Pain items demonstrated remarkable similarity among age cohorts. Health indicators were significant and in the expected direction (p < .001). An increase in comorbidity, ADL and IADL dependence, worse self-rated health, and more depressive symptoms were each significantly more common among participants who reported moderate or greater pain compared to none to mild pain. Discussion. Pain presence, location, and intensity measures were successfully integrated into NSHAP Wave 2 and exhibit construct and external validity. PMID:25360020

    The Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) predicts increased risk of opioid misuse in chronic pain patients. We evaluated whether higher SOAPP-R scores are associated with greater opioid reinforcing properties, potentially contributing to their predictive utility. Across two counterbalanced laboratory sessions, 55 chronic low back pain sufferers completed the SOAPP-R at baseline, and measures of back pain intensity, evoked pain responsiveness (thermal, ischemic), and subjective opioid effects after receiving intravenous morphine (0.08 mg/kg) or saline placebo. Morphine effect measures were derived for all outcomes reflecting the difference between morphine and placebo condition values. Higher SOAPP-R scores were significantly associated with greater desire to take morphine again, less feeling down and feeling bad, and greater reductions in sensory low back pain intensity following morphine administration. This latter effect was due primarily to SOAPP-R content assessing medication-specific attitudes and behavior. Individuals exceeding the clinical cutoff (18 or more) on the SOAPP-R exhibited significantly greater morphine liking, desire to take morphine again, and feeling sedated; lower feeling bad; and greater reductions in sensory low back pain following morphine. The SOAPP-R may predict elevated opioid risk in part by tapping into individual differences in opioid reinforcing effects. PMID:25892658

    CAM therapies have become increasingly popular in pediatric populations. Yet, little is known about children's preferences for CAM. This study examined treatment preferences in chronic pediatric pain patients offered a choice of CAM therapies for their pain. Participants were 129 children (94 girls) (mean age = 14.5 years +/- 2.4; range = 8-18 years) presenting at a multidisciplinary, tertiary clinic specializing in pediatric chronic pain. Bivariate and multivariate analyses were used to examine the relationships between CAM treatment preferences and patient's sociodemographic and clinical characteristics, as well as their self-reported level of functioning. Over 60% of patients elected to try at least one CAM approach for pain. The most popular CAM therapies were biofeedback, yoga and hypnosis; the least popular were art therapy and energy healing, with craniosacral, acupuncture and massage being intermediate. Patients with a diagnosis of fibromyalgia (80%) were the most likely to try CAM versus those with other pain diagnoses. In multivariate analyses, pain duration emerged as a significant predictor of CAM preferences. For mind-based approaches (i.e. hypnosis, biofeedback and art therapy), pain duration and limitations in family activities were both significant predictors. When given a choice of CAM therapies, this sample of children with chronic pain, irrespective of pain diagnosis, preferred non-invasive approaches that enhanced relaxation and increased somatic control. Longer duration of pain and greater impairment in functioning, particularly during family activities increased the likelihood that such patients agreed to engage in CAM treatments, especially those that were categorized as mind-based modalities.

    Objective: This study aimed at developing an experimental paradigm to assess vicarious pain experiences. We further explored the putative moderating role of observer's characteristics such as hypervigilance for pain and dispositional empathy. Methods: Two experiments are reported using a similar procedure. Undergraduate students were selected based upon whether they reported vicarious pain in daily life, and categorized into a pain responder group or a comparison group. Participants were presented a series of videos showing hands being pricked whilst receiving occasionally pricking (electrocutaneous) stimuli themselves. In congruent trials, pricking and visual stimuli were applied to the same spatial location. In incongruent trials, pricking and visual stimuli were in the opposite spatial location. Participants were required to report on which location they felt a pricking sensation. Of primary interest was the effect of viewing another in pain upon vicarious pain errors, i.e., the number of trials in which an illusionary sensation was reported. Furthermore, we explored the effect of individual differences in hypervigilance to pain, dispositional empathy and the rubber hand illusion (RHI) upon vicarious pain errors. Results: Results of both experiments indicated that the number of vicarious pain errors was overall low. In line with expectations, the number of vicarious pain errors was higher in the pain responder group than in the comparison group. Self-reported hypervigilance for pain lowered the probability of reporting vicarious pain errors in the pain responder group, but dispositional empathy and the RHI did not. Conclusion: Our paradigm allows measuring vicarious pain experiences in students. However, the prevalence of vicarious experiences of pain is low, and only a small percentage of participants display the phenomenon. It remains however unknown which variables affect its occurrence.

    Abstract Safe and effective management of acute dental pain can be accomplished with nonopioid and opioid analgesics. To formulate regimens properly, it is essential to appreciate basic pharmacological principles and appropriate dosage strategies for each of the available analgesic classes. This article will review the basic pharmacology of analgesic drug classes, including their relative efficacy for dental pain, and will suggest appropriate regimens based on pain intensity. Management of chronic pain will be addressed in the second part of this series. PMID:20553137
