  2. Opioid Therapy for Chronic Nonmalignant Pain

    Directory of Open Access Journals (Sweden)

    Russell K Portenoy


    Full Text Available Long term administration of an opioid drug for chronic nonmalignant pain continues to be controversial, but is no longer uniformly rejected by pain specialists. This is true despite concerns that the regulatory agencies that oversee physician prescribing of opioid drugs continue to stigmatize the practice. The changing clinical perspective has been driven, in part, by widespread acknowledgement of the remarkably favourable outcomes achieved during opioid treatment of cancer pain. These outcomes contrast starkly with popular teaching about chronic opioid therapy and affirm the potential for prolonged efficacy, tolerable side effects, enhanced function associated with improved comfort and minimal risk of aberrant drug-related behaviours consistent with addiction. A large anecdotal experience in populations with nonmalignant pain suggests that these patients are more heterogeneous and that opioid therapy will greatly benefit some and will contribute to negative outcomes for others. The few controlled clinical trials that have been performed support the safety and efficacy of opioid therapy, but have been too limited to ensure generalization to the clinical setting. A critical review of the medical literature pertaining to chronic pain, opioid pharmacology and addiction medicine can clarify misconceptions about opioid therapy and provide a foundation for patient selection and drug administration. The available data support the view that opioids are no panacea for chronic pain, but should be considered in carefully selected patients using clinically derived guidelines that stress a structured approach and ongoing monitoring of efficacy, adverse effects, functional outcomes and the occurrence of aberrant drug-related behaviours.

  3. Effect of chronic nonmalignant pain on highway driving performance. (United States)

    Veldhuijzen, D S; van Wijck, A J M; Wille, F; Verster, J C; Kenemans, J L; Kalkman, C J; Olivier, B; Volkerts, E R


    Most pain patients are treated in an outpatient setting and are engaged in daily activities including driving. Since several studies showed that cognitive functioning may be impaired in chronic nonmalignant pain, the question arises whether or not chronic nonmalignant pain affects driving performance. Therefore, the objective of the present study was to determine the effects of chronic nonmalignant pain on actual highway driving performance during normal traffic. Fourteen patients with chronic nonmalignant pain and 14 healthy controls, matched on age, educational level, and driving experience, participated in the study. Participants performed a standardized on-the-road driving test during normal traffic, on a primary highway. The primary parameter of the driving test is the Standard Deviation of Lateral Position (SDLP). In addition, driving-related skills (tracking, divided attention, and memory) were examined in the laboratory. Subjective assessments, such as pain intensity, and subjective driving quality, were rated on visual analogue scales. The results demonstrated that a subset of chronic nonmalignant pain patients had SDLPs that were higher than the matched healthy controls, indicating worse highway driving performance. Overall, there was a statistically significant difference in highway driving performance between the groups. Further, chronic nonmalignant pain patients rated their subjective driving quality to be normal, although their ratings were significantly lower than those of the healthy controls. No significant effects were found on the laboratory tests.

  6. An update on the role of opioids in the management of chronic pain of nonmalignant origin. (United States)

    Højsted, Jette; Sjøgren, Per


    To summarize and reflect over primarily recent epidemiological and randomized controlled trials in opioid-treated chronic nonmalignant pain patients, focusing on effects, side effects, risks and long-term consequences of the treatment. In the western world opioids are increasingly being used for long-term treatment of chronic nonmalignant pain. While the long-term benefits of opioids regarding pain relief, functional capacity and health-related quality of life still remain to be proven, studies are emerging that describe serious long-term consequences such as addiction, opioid-induced hyperalgesia, cognitive disorders, and suppression of the immune and reproductive systems. Much more research is needed concerning long-time effects and consequences of opioid therapy in chronic nonmalignant pain patients; however, some clear warning signals have been sent out within recent years.

    Full Text Available Igor Kissin Department of Anesthesiology, Perioperative, and Pain Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA Background: For the past 30 years, opioids have been used to treat chronic nonmalignant pain. This study tests the following hypotheses: (1 there is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective; and (2 the main problem associated with the safety of such treatment – assessment of the risk of addiction – has been neglected. Methods: Scientometric analysis of the articles representing clinical research in this area was performed to assess (1 the quality of presented evidence (type of study; and (2 the duration of the treatment phase. The sufficiency of representation of addiction was assessed by counting the number of articles that represent (1 editorials; (2 articles in the top specialty journals; and (3 articles with titles clearly indicating that the addiction-related safety is involved (topic-in-title articles. Results: Not a single randomized controlled trial with opioid treatment lasting >3 months was found. All studies with a duration of opioid treatment ≥6 months (n = 16 were conducted without a proper control group. Such studies cannot provide the consistent good-quality evidence necessary for a strong clinical recommendation. There were profound differences in the number of addiction articles related specifically to chronic nonmalignant pain patients and to opioid addiction in general. An inadequate number of chronic pain-related publications were observed with all three types of counted articles: editorials, articles in the top specialty journals, and topic-in-title articles. Conclusion: There is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective. The above identified signs indicating neglect of addiction associated with the

  10. Polysomnographic characteristics in nonmalignant chronic pain populations: A review of controlled studies. (United States)

    Bjurstrom, Martin F; Irwin, Michael R


    Sleep and pain are critical homeostatic systems that interact in a bidirectional manner. Complaints of sleep disturbance are ubiquitous among patients with chronic pain disorders, and conversely, patients with persistent insomnia symptoms commonly report suffering from chronic pain. Sleep deprivation paradigms demonstrate that partial or complete sleep loss induce hyperalgesia, possibly due to shared mechanistic pathways including neuroanatomic and molecular substrates. Further, chronic pain conditions and sleep disturbances are intertwined through comorbidities, which together cause detrimental psychological and physical consequences. This critical review examines 29 polysomnography studies to evaluate whether nonmalignant chronic pain patients, as compared to controls, show differences in objective measures of sleep continuity and sleep architecture. Whereas these controlled studies did not reveal a consistent pattern of objective sleep disturbances, alterations of sleep continuity were commonly reported. Alterations of sleep architecture such as increases in light sleep or decreases in slow-wave sleep were less commonly reported and findings were mixed and also inconsistent. Methodological flaws were identified, which complicated interpretation and limited conclusions; hence, recommendations for future research are suggested. Knowledge of abnormalities in the sleep process has implications for understanding the pathophysiology of chronic pain conditions, which might also direct the development of novel intervention strategies.

  11. Oral opioid administration and hyperalgesia in patients with cancer or chronic nonmalignant pain. (United States)

    Reznikov, Igor; Pud, Dorit; Eisenberg, Elon


    Previous research has reported on reduced paw withdrawal latencies to heat and mechanical stimuli after parenteral administration of opioids in animals and on increased pain sensitivity in humans subsequent to postoperative infusions of short-acting opioids or in drug addicts. The aim of the present study was to explore the possibility that oral opioid treated patients with cancer-related or chronic nonmalignant pain differ in their pain sensitivity from patients treated with non-opioid analgesics. The study population consisted of 224 patients, including 142 in the opioid-treated group and 82 in the non-opioid-treated group. Pain thresholds for punctuate measured by von Frey filaments (g), mechanical pressure measured by pressure algometer (mmHg), heat stimuli measured by quantitative sensory testing (degrees C), as well as suprathreshold tonic heat pain intensity (46.5 degrees C for 1 min) measured by 0-10 numerical pain scale (NPS) were obtained at a nonpainful site (thenar eminence) in all patients. No differences between the groups were found for gender, age, duration of pain, or duration of treatment (independent variables). No significant differences between the groups were found in punctuate (difference = 17.0 g (95% CI -8.8, 42.8), P = 0.19), pressure (2.2 mmHg (-28.7, 33.2), P = 0.89) and heat (-0.3 degrees C (-1.5, 0.9), P = 0.70) pain thresholds, or in suprathreshold heat pain intensity (difference between maximal pain intensities -0.4 NPS units (95% CI -1.2, 0.4), P = 0.31). Pearson correlations within the opioid-treated group failed to show significant relationships between any of the independent variables and the outcome measures. A further comparison of the outcomes between the 'weak' opioid-treated subgroup and the 'strong' opioid-treated subgroup again revealed insignificant results. These results suggest that the administration of 'commonly used' dosages of oral opioids does not result in abnormal pain sensitivity beyond that of patients

  12. Subanesthetic, Subcutaneous Ketamine Infusion Therapy in the Treatment of Chronic Nonmalignant Pain. (United States)

    Zekry, Olfat; Gibson, Stephen B; Aggarwal, Arun


    This study was designed to describe the efficacy and toxicity of subcutaneous ketamine infusions and sublingual ketamine lozenges for the treatment of chronic nonmalignant pain. Data were collected prospectively on 70 subjects managed in an academic, tertiary care hospital between 2007 and 2012 who received between 3 and 7 days of subanesthetic, subcutaneous ketamine infusion. Data were analyzed for efficacy, adverse effects, and reduction in use of opioid medication. We also analyzed whether subsequent treatment with sublingual ketamine lozenges resulted in longer-term efficacy of the beneficial effects of the initial ketamine infusion. There was a significant reduction in pain intensity measured by numerical rating scale (NRS) from mean of 6.38 before ketamine to 4.60 after ketamine (P ketamine infusion from a mean morphine equivalent dose (MMED) of 216 mg/day before ketamine to 89 mg/day after ketamine (P ketamine infusion was 59%. No subjects increased their use of opioids during their hospitalization for the ketamine infusion. A small proportion of subjects who responded to the infusion were continued on ketamine lozenges. This group was followed for between 3 months and 2 years. The use of ketamine lozenges after the infusion resulted in 31% of these subjects being able to cease their use of opioids compared with only 6% who did not receive ketamine lozenges. Eleven percent of subjects who received lozenges subsequently increased their opioid usage. Adverse effects were fairly common, but only mild, with 46% of patients experiencing light-headedness and dizziness, 25% tiredness and sedation, 12% headaches, 12% hallucinations, and 8% vivid dreams. Adverse effects were easily managed by reducing the rate of the ketamine infusion. The administration of subanesthetic, subcutaneous ketamine infusion was well tolerated, with mostly mild adverse effects and no serious adverse effects. The infusion provided significant pain relief in subjects who had failed a wide

    Cámara, Rafael J A; Merz, Christian; Wegmann, Barbara; Stauber, Stefanie; von Känel, Roland; Egloff, Niklaus


    Objectives. We compared two index screening tests for early diagnosis of functional pain: pressure pain measurement by electronic diagnostic equipment, which is accurate but too specialized for primary health care, versus peg testing, which is cost-saving and more easily manageable but of unknown sensitivity and specificity. Early distinction of functional (altered pain perception; nervous sensitization) from neuropathic or nociceptive pain improves pain management. Methods. Clinicians blinded for the index screening tests assessed the reference standard of this noninferiority diagnostic accuracy study, namely, comprehensive medical history taking with all previous findings and treatment outcomes. All consenting patients referred to a university hospital for nonmalignant musculoskeletal pain participated. The main analysis compared the receiver operating characteristic (ROC) curves of both index screening tests. Results. The area under the ROC curve for peg testing was not inferior to that of electronic equipment: it was at least 95% as large for finger measures (two-sided p = 0.038) and at least equally as large for ear measures (two-sided p = 0.003). Conclusions. Routine diagnostic testing by peg, which is accessible for general practitioners, is at least as accurate as specialized equipment. This may shorten time-to-treatment in general practices, thereby improving the prognosis and quality of life.

  14. Faculty Communication Knowledge, Attitudes, and Skills Around Chronic Non-Malignant Pain Improve with Online Training. (United States)

    Donovan, Anna K; Wood, Gordon J; Rubio, Doris M; Day, Hollis D; Spagnoletti, Carla L


    Many physicians struggle to communicate with patients with chronic, non-malignant pain (CNMP). Through the use of a Web module, the authors aimed to improve faculty participants' communication skills knowledge and confidence, use of skills in clinical practice, and actual communication skills. The module was implemented for faculty development among clinician-educators with university faculty appointments, outpatient clinical practices, and teaching roles. Participants completed the Collaborative Opioid Prescribing Education Risk Evaluation and Mitigation Strategy (COPE-REMS®) module, a free Web module designed to improve provider communication around opioid prescribing. Main study outcomes were improvements in CNMP communication knowledge, attitudes, and skills. Skills were assessed by comparing a subset of participants' Observed Structured Clinical Exam (OSCE) performance before and after the curriculum. Sixty-two percent of eligible participants completed the curriculum in 2013. Knowledge-based test scores improved with curriculum completion (75% vs. 90%; P communication skills on the OSCE improved after the curriculum (mean 67% vs. 79%, P = 0.03). Experienced clinician-educators improved their communication knowledge, attitudes, and skills in managing patients with CNMP after implementation of this curriculum. The improvements in attitudes were sustained at six months. A Web-based curriculum such as COPE-REMS® may be useful for other programs seeking improvement in faculty communication with patients who have CNMP. © 2016 American Academy of Pain Medicine.

  15. Meta-ethnography to understand healthcare professionals’ experience of treating adults with chronic non-malignant pain (United States)

    Seers, Kate; Barker, Karen L


    Objectives We aimed to explore healthcare professionals’ experience of treating chronic non-malignant pain by conducting a qualitative evidence synthesis. Understanding this experience from the perspective of healthcare professionals will contribute to improvements in the provision of care. Design Qualitative evidence synthesis using meta-ethnography. We searched five electronic bibliographic databases from inception to November 2016. We included studies that explore healthcare professionals’ experience of treating adults with chronic non-malignant pain. We used the GRADE-CERQual framework to rate confidence in review findings. Results We screened the 954 abstracts and 184 full texts and included 77 published studies reporting the experiences of over 1551 international healthcare professionals including doctors, nurses and other health professionals. We abstracted six themes: (1) a sceptical cultural lens, (2) navigating juxtaposed models of medicine, (3) navigating the geography between patient and clinician, (4) challenge of dual advocacy, (5) personal costs and (6) the craft of pain management. We rated confidence in review findings as moderate to high. Conclusions This is the first qualitative evidence synthesis of healthcare professionals’ experiences of treating people with chronic non-malignant pain. We have presented a model that we developed to help healthcare professionals to understand, think about and modify their experiences of treating patients with chronic pain. Our findings highlight scepticism about chronic pain that might explain why patients feel they are not believed. Findings also indicate a dualism in the biopsychosocial model and the complexity of navigating therapeutic relationships. Our model may be transferable to other patient groups or situations.

  18. A mega-ethnography of eleven qualitative evidence syntheses exploring the experience of living with chronic non-malignant pain. (United States)

    Toye, Fran; Seers, Kate; Hannink, Erin; Barker, Karen


    Each year over five million people develop chronic non-malignant pain and can experience healthcare as an adversarial struggle. The aims of this study were: (1) to bring together qualitative evidence syntheses that explore patients' experience of living with chronic non-malignant pain and develop conceptual understanding of what it is like to live with chronic non-malignant pain for improved healthcare; (2) to undertake the first mega-ethnography of qualitative evidence syntheses using the methods of meta-ethnography. We used the seven stages of meta-ethnography refined for large studies. The innovation of mega-ethnography is to use conceptual findings from qualitative evidence syntheses as primary data. We searched 7 bibliographic databases from inception until February 2016 to identify qualitative evidence syntheses that explored patients' experience of living with chronic non-malignant pain. We identified 82 potential studies from 556 titles, screened 34 full text articles and included 11 qualitative evidence syntheses synthesising a total of 187 qualitative studies reporting more than 5000 international participants living with chronic pain. We abstracted concepts into 7 conceptual categories: (1) my life is impoverished and confined; (2) struggling against my body to be me; (3) the quest for the diagnostic 'holy grail'; (4) lost personal credibility; (5) trying to keep up appearances; (6) need to be treated with dignity; and (7) deciding to end the quest for the grail is not easy. Each conceptual category was supported by at least 7 of the 11 qualitative evidence syntheses. This is the first mega-ethnography, or synthesis of qualitative evidence syntheses using the methods of meta-ethnography. Findings help us to understand that the decision to end the quest for a diagnosis can leave patients feeling vulnerable and this may contribute to the adversarial nature of the clinical encounter. This knowledge demonstrates that treating a patient with a sense that they

  19. The Effect of Curanderismo on Chronic Non-malignant Pain: A Case Report. (United States)

    Kennedy, Laura; Gonzales, Erin; Corbin, Lisa


    This case study describes the effects of the use of curanderismo, an indigenous healing modality combining techniques in massage, sound, and aromatherapy, on a patient with chronic pain. Despite being a commonly used health practice in certain populations, little is reported in the medical literature about the use of curanderismo. Case report as part of a larger randomized trial of curanderismo for chronic pain. Setting was a community-based hospital affiliated primary care clinic. An adult patient with chronic, opioid dependent back pain following an injury, and subsequent spinal fusion was treated. Intervention was the patient received 33 curanderismo treatment sessions over 10 months in addition to ongoing conventional treatment at a community-based chronic pain management clinic. Main outcomes measures were self-reported assessments of pain, functional ability, mood, insomnia, and narcotic usage. Secondary outcome measure was qualitative interview. Although there was no change in quantitative self-reported pain measures, the patient reported improved function, mood, and sleep as well as decreased narcotic usage. Curanderismo, in addition to conventional pain management, improved patient reported symptoms and functional ability, led to healthy lifestyle changes, and decreased narcotic usage. Controlled studies are needed to confirm the benefit of curanderismo as safe, non-interventional, and cost-effective adjunct for chronic pain management. Copyright © 2016 Elsevier Inc.

    Ott, Oliver J.; Niewald, Marcus; Weitmann, Hajo-Dirk; Jacob, Ingrid; Adamietz, Irenaeus A.; Schaefer, Ulrich; Keilholz, Ludwig; Heyd, Reinhard; Muecke, Ralph


    The purpose of this article is to summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign painful degenerative skeletal disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of enthesiopathies (shoulder syndrome, trochanteric bursitis, plantar fasciitis, and elbow syndrome) and painful arthrosis (knee, hip, hand, and finger joints). The most relevant aspects of the DEGRO S2e Consensus Guideline Radiation Therapy of Benign Diseases 2014 regarding diagnostics, treatment decision, dose prescription as well as performance of radiotherapy and results are summarized. For all indications mentioned above, retrospective and some prospective analyses have shown remarkable effects in terms of pain relief. Nevertheless, the Level of Evidence (LoE) and the Grade of Recommendation (GR) vary: LoE 1b-4 and GR A-C. Low-dose radiotherapy for painful degenerative skeletal disorders is effective in the majority of the patients and therefore it may be a reasonable therapeutic alternative when simple and non-invasive methods have been used without persistent success. For all discussed entities, single fraction doses of 0.5-1.0 Gy and total doses of 3.0-6.0 Gy/series applied with 2-3 fractions per week are recommended. (orig.) [de

    Full Text Available We report a case of 42-year-old male patient with hypogonadotropic hypogonadism. He suffered from general fatigue and erectile dysfunction after the treatment with transdermal fentanyl for chronic pain by traffic injury. Endocrine examinations and hormone stimulating tests showed that he had hypogonadotropic hypogonadism. Brain magnetic resonance imaging (MRI showed no abnormal findings, and he had no past history of accounting for acquired hypogonadotropic hypogonadism. Therefore, his hypogonadism was diagnosed to be caused by opioid treatment. Although opioid-induced endocrine dysfunctions are not widely recognized, this case suggests that we should consider the possibility of endocrine dysfunctions in patients with opioid treatment.

  5. Correlates and management of nonmalignant pain in the nursing home. SAGE Study Group. Systematic Assessment of Geriatric drug use via Epidemiology. (United States)

    Won, A; Lapane, K; Gambassi, G; Bernabei, R; Mor, V; Lipsitz, L A


    Nonmalignant pain is a common problem among older people. The prevalence of pain in the nursing home is not well studied. We looked at the association between nonmalignant pain, psychological and functional health, and the practice patterns for pain management in the nursing home. A cross-sectional study. Nursing Home in four US states. A total of 49,971 nursing home residents from 1992 to 1995. We used the SAGE database (Systematic Assessment of Geriatric drug use via Epidemiology), which linked information from the Minimum Data Set and nursing home drug utilization data. The MDS items measured included pain, activities of daily living (ADL) function, mood, and time involved in activities. The use of analgesics, anxiolytics, and antidepressants was also documented. Daily pain was reported in 26% of nursing home residents. The prevalence was lower among men, persons more than age 85, and racial minorities. Persons suffering pain daily were more likely to have severe ADL impairment, odds ratio (OR) (2.47 (95% CI, 2.34-2.60)), more depressive signs and symptoms (OR 1.66 (95% CI, 1.57-1.75)), and less frequent involvement in activities (OR 1.35 (95% CI, 1.29-1.40)). Approximately 25% of persons with daily pain received no analgesics. Residents who were more than 85 years old (OR 1.15 (95% CI 1.02-1.28)), cognitively impaired, (OR 1.44 (95% CI, 1.29-1.61)), of male gender (OR 1.17 (95% CI, 1.06-1.29)), or a racial minority (OR 1.69 (95% CI, 1.40-2.05) and OR 1.56 (95% CI, 0.70-1.04) for blacks and Hispanics, respectively) were at greater risk of not receiving analgesics. Approximately 50% of those in pain used physical and occupational therapies, which was more than two times higher (OR 2.44 (95% CI, 2.34-2.54)), than use for those not in pain. Daily nonmalignant pain is prevalent among nursing home residents and is often associated with impairments in ADL, mood, and decreased activity involvement. Even when pain was recognized, men, racial minorities, and cognitively

  6. Sleep behaviors in older African American females reporting nonmalignant chronic pain: understanding the psychosocial implications of general sleep disturbance. (United States)

    Baker, Tamara A; Whitfield, Keith E


    This study examined factors that influence sleep quality in older African American women (N = 181) reporting chronic pain. Participants completed a series of questions assessing demographic and behavioral characteristics, health status, pain intensity, and sleep disturbance. Findings indicated that younger participants and those experiencing poorer physical functioning reported more difficulty sleeping due to pain. Similarly, participants who reported being awakened from sleep due to pain were younger and experienced greater pain intensity. Understanding the relationship between sleep and pain in this group of women may be useful in promoting effective disease management and sleep awareness among patients, caregivers, and healthcare professionals.

  7. [The Competence Network Parkinson (CNP)]. (United States)

    Oertel, Wolfgang H; Deuschl, Guenther; Eggert, Karla


    The Competence Network Parkinson (CNP) is a research infrastructure for disease-oriented translational and clinical research in the field of Parkinson syndromes (PS). It was initiated in 1999 and funded until 2008 by the German Ministry for Education and Research (BMBF). The CNP created a highly frequented website with information on PS for the general public and for experts. The CNP designed and established one of the first electronic internet-based data entry systems (secuTrial®) - fulfilling the legal standards of data safety and security - a material bank for genetic research on Parkinson's disease (PD), implemented and investigated new methods for early diagnosis of PD and related atypical PS including in vivo dopamine transporter imaging (DAT SPECT), established the German Parkinson Study Group (GPS-Pharma) with 40 certified trial centres for pharmacotherapeutical trials and the German interdisciplinary Parkinson Study Group (neurology and neurosurgery) for deep brain stimulation (GPS-DBS), and carried out several pharmacoeconomic and health care studies on PD in Germany. Sustainability of the infrastructure CNP has in part been achieved in form of the GPS-Pharma and the GPS-DBS, as well as in the German Study Group on REM Sleep Behaviour Disorder (RBD), a prodromal phase of PD. Part of the CNP activities, such as genetic research and research on cohorts of PD patients, have been incorporated into the German Center for Neurodegenerative Disorders (DZNE). Furthermore, topics such as health care research are funded within projects of the EU research program. The article describes problems in setting up a competence network from scratch and contains recommendations how to avoid them in the future.

  8. Circulatory CNP Rescues Craniofacial Hypoplasia in Achondroplasia. (United States)

    Yamanaka, S; Nakao, Kazumasa; Koyama, N; Isobe, Y; Ueda, Y; Kanai, Y; Kondo, E; Fujii, T; Miura, M; Yasoda, A; Nakao, Kazuwa; Bessho, K


    Achondroplasia is the most common genetic form of human dwarfism, characterized by midfacial hypoplasia resulting in occlusal abnormality and foramen magnum stenosis, leading to serious neurologic complications and hydrocephalus. Currently, surgery is the only way to manage jaw deformity, neurologic complications, and hydrocephalus in patients with achondroplasia. We previously showed that C-type natriuretic peptide (CNP) is a potent stimulator of endochondral bone growth of long bones and vertebrae and is also a potent stimulator in the craniofacial region, which is crucial for midfacial skeletogenesis. In this study, we analyzed craniofacial morphology in a mouse model of achondroplasia, in which fibroblast growth factor receptor 3 (FGFR3) is specifically activated in cartilage ( Fgfr3 ach mice), and investigated the mechanisms of jaw deformities caused by this mutation. Furthermore, we analyzed the effect of CNP on the maxillofacial area in these animals. Fgfr3 ach mice exhibited midfacial hypoplasia, especially in the sagittal direction, caused by impaired endochondral ossification in craniofacial cartilage and by premature closure of the spheno-occipital synchondrosis, an important growth center in craniomaxillofacial skeletogenesis. We crossed Fgfr3 ach mice with transgenic mice in which CNP is expressed in the liver under the control of the human serum amyloid-P component promoter, resulting in elevated levels of circulatory CNP ( Fgfr3 ach /SAP-Nppc-Tg mice). In the progeny, midfacial hypoplasia in the sagittal direction observed in Fgfr3 ach mice was improved significantly by restoring the thickness of synchondrosis and promoting proliferation of chondrocytes in the craniofacial cartilage. In addition, the foramen magnum stenosis observed in Fgfr3 ach mice was significantly ameliorated in Fgfr3 ach /SAP-Nppc-Tg mice due to enhanced endochondral bone growth of the anterior intraoccipital synchondrosis. These results clearly demonstrate the therapeutic

    Robert B Coambs


    Full Text Available BACKGROUND: Many physicians are overly cautious about prescribing opioids for chronic pain because of fears of iatrogenic addiction. However, in patients with chronic pain, addiction to opioid analgesics is exceedingly rare when there is no prior history of alcohol or drug abuse.

  10. Health-related quality of life in fibromyalgia and refractory angina pectoris: a comparison between two chronic non-malignant pain disorders. (United States)

    Andréll, Paulin; Schultz, Tomas; Mannerkorpi, Kaisa; Nordeman, Lena; Börjesson, Mats; Mannheimer, Clas


    To compare health-related quality of life in 2 different populations with chronic pain: patients with fibromyalgia and patients with refractory angina pectoris. Previous separate studies have indicated that these patient groups report different impacts of pain on health-related quality of life. The Short-Form 36 was used to assess health- related quality of life. In order to adjust for age and gender differences between the groups, both patient groups were compared with age- and gender-matched normative controls. The difference in health-related quality of life between the 2 patient groups was assessed by transforming the Short-Form 36 subscale scores to a z-score. The patients with fibromyalgia (n = 203) reported poorer health-related quality of life in all the subscale scores of Short-Form 36 (p fibromyalgia experience greater impairment in health-related quality of life compared with the normal population than do patients with refractory angina pectoris, despite the fact that the latter have a potentially life-threatening disease. The great impairment in health- related quality of life in patients with fibromyalgia should be taken into consideration when planning rehabilitation.

  11. Patients with Concomitant Chronic Neck Pain and Myofascial Pain in Masticatory Muscles Have More Widespread Pain and Distal Hyperalgesia than Patients with Only Chronic Neck Pain. (United States)

    Muñoz-García, Daniel; López-de-Uralde-Villanueva, Ibai; Beltrán-Alacreu, Héctor; La Touche, Roy; Fernández-Carnero, Josué


    Insufficient evidence exists to compare widespread pain (WP), pain sensibility, and psychological factors that occur in patients presenting with chronic neck pain (CNP) or a combination of temporomandibular disorder (TMD) and other complaints. The present study compared the pain sensibility and psychological factors of subjects with CNP with those with TMD + CNP. Cross-sectional study. Local community. A nonprobabilistic convenience sample of 86 persons with CNP or TMD was recruited into three groups: CNP, TMD with myofascial pain in masticatory muscles with cocomitant CNP (TMD + CNP), and asymptomatic control groups consisted of 27, 29, and 30 participants, respectively. Participants underwent a clinical examination to evaluate WP with computerized assessment based on the pain drawing, pressure pain thresholds (PPT), and psychological factors, which were evaluated using the pain catastrophizing scale (PCS) and the state-trait anxiety inventory (STAI). Statistically significant differences were observed between participants with CNP and TMD + CNP for WP (t = -2.80, P  < 0.01, d = -1.06). Post hoc analyses only revealed significant differences between TMD + CNP participants and asymptomatic controls for PPT at extratrigeminal areas. Pearson correlation analyses showed a moderate positive association between symptomatic groups within the WP and STAI ( P  < 0.05) and a moderate negative association between PCS and PPT ( P  < 0.05) at the right tibialis muscle. TMD + CNP participants had more areas of pain and also showed widespread pain hyperalgesia. Both groups of participants had psychological factors positively associated with STAI and WP; further, PCS and the PPT at the extratrigeminal region were negatively associated with each other in both groups, except for the left tibialis in the TMD + CNP group. © 2016 American Academy of Pain Medicine.

  12. Increased psychological distress among individuals with spinal cord injury is associated with central neuropathic pain rather than the injury characteristics. (United States)

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


    Cross-sectional study. Central neuropathic pain (CNP) is common after spinal cord injury (SCI). The psychological impact of CNP is not clear. Previous studies reported depression and pain catastrophizing among patients with SCI and CNP; however, the lack of control groups prevented discerning whether these were attributed to CNP or to the SCI itself. The aim was to examine the psychological distress among individuals with SCI with and without CNP and controls to evaluate its impact and possible source. Outpatient clinic of a large rehabilitation center. Individuals with SCI and CNP (n = 27) and without CNP (n = 23), and able-bodied controls (n = 20) participated. Data collection included sociodemographics, SCI characteristics, and level of post-traumatic stress disorder (PTSD), anxiety, stress, depression, and pain catastrophizing. The sensory, affective, and cognitive dimensions of CNP were analyzed. Individuals with SCI and CNP exhibited elevated levels of PTSD, anxiety, stress, depression, and pain catastrophizing compared to the two control groups, which presented similar levels. The psychological variables among the CNP group correlated positively only with the affective dimension of CNP. Neither CNP nor the psychological variables correlated with SCI characteristics. Irrespective of CNP intensity, the affective dimension (suffering) is associated with increased psychological distress. Perhaps individual differences in the response to SCI and/or individual traits rather than the mere exposure to SCI may have a role in the emergence of CNP and psychological distress/mood dysfunction. Rehabilitation programs should prioritize stress management and prevention among individuals with SCI and CNP.

    Objective: To develop a RIA kit for measurement of C-type natriuretic peptide (CNP) and to investigate its in clinical use. Methods: Conjugated CNP-TG was used to immunize the rabbit and the antibody against CNP was prepared. CNP RIA kits were made from it. Plasma CNP concentrations of 83 controls, 54 patients with coronary heart disease, 25 patients with heart failure and 73 patients with primary hypertension were determined with this RIA kit. Results: The sensitivity of detection was 5 pg/ml. The specificity of CNP anti-serum was high and did not react with ANP, NT, NPY, ET, CGRP and CT. The intra and interassy CVs were <10% and <15% respectively. The plasma levels of patients with coronary heart disease, heart failure and primary hypertension were 62.5 pg/ml, 47.9 pg/ml, 56.4 pg/ml respectively. There were all significantly higher than the level in controls (27.5 pg/ml). Conclusion: RIA of CNP with this kit is a simple, rapid method. It is a reliable means for studying the role of CNP in various physiological and pathophysiological states

  15. Radiotherapy for non-malignant disorders

    International Nuclear Information System (INIS)

    Seegenschmiedt, Michael Heinrich; Makoski, Hans-Bruno; Trott, Klaus-Ruediger; Brady, Luther W.


    This volume discusses the general background, radiobiology, radiophysics and clinical applications of radiation therapy in the treatment of non-malignant diseases. Within 39 chapters, it documents the rationale and indications for the use of state-of-the-art radiotherapy for various non-malignant disorders of the CNS, head and neck, eye, skin and soft tissues, bone and joints, and the vascular system. In so doing, it draws attention to and elucidates the scope for application of radiotherapy beyond the treatment of malignancies. Both the risks and the benefits of such treatment are fully considered, the former ranging from minor clinical problems to life-threatening diseases. With the assistance of many tables and colored figures, the extensive data from clinical studies are presented in a well-structured and informative way. Each chapter concludes with a list of key points, allowing the reader to quickly comprehend the main facts. Since this approach offers an interdisciplinary perspective, this book will be of interest not only to radiotherapists but also to many other practitioners and medical specialists, for example orthopedists, surgeons, and ophthalmologists.

  16. Dynamic oscillatory signatures of central neuropathic pain in spinal cord injury. (United States)

    Vuckovic, Aleksandra; Hasan, Muhammad A; Fraser, Matthew; Conway, Bernard A; Nasseroleslami, Bahman; Allan, David B


    Central neuropathic pain (CNP) is believed to be accompanied by increased activation of the sensorimotor cortex. Our knowledge of this interaction is based mainly on functional magnetic resonance imaging studies, but there is little direct evidence on how these changes manifest in terms of dynamic neuronal activity. This study reports on the presence of transient electroencephalography (EEG)-based measures of brain activity during motor imagery in spinal cord-injured patients with CNP. We analyzed dynamic EEG responses during imaginary movements of arms and legs in 3 groups of 10 volunteers each, comprising able-bodied people, paraplegic patients with CNP (lower abdomen and legs), and paraplegic patients without CNP. Paraplegic patients with CNP had increased event-related desynchronization in the theta, alpha, and beta bands (16-24 Hz) during imagination of movement of both nonpainful (arms) and painful limbs (legs). Compared to patients with CNP, paraplegics with no pain showed a much reduced power in relaxed state and reduced event-related desynchronization during imagination of movement. Understanding these complex dynamic, frequency-specific activations in CNP in the absence of nociceptive stimuli could inform the design of interventional therapies for patients with CNP and possibly further understanding of the mechanisms involved. This study compares the EEG activity of spinal cord-injured patients with CNP to that of spinal cord-injured patients with no pain and also to that of able-bodied people. The study shows that the presence of CNP itself leads to frequency-specific EEG signatures that could be used to monitor CNP and inform neuromodulatory treatments of this type of pain.

  17. Higher level of NT-proCNP in cerebrospinal fluid of patients with meningitis. (United States)

    Tomasiuk, Ryszard; Lipowski, Dariusz; Szlufik, Stanislaw; Peplinska, Krystyna; Mikaszewska-Sokolewicz, Malgorzata


    Aminoterminal pro-C type natriuretic peptide (NT-proCNP) as an active form of CNP, has been recently proven to be a potential marker of sepsis and to be linked to inflammatory diseases. So far, there are no studies describing the level of NT-proCNP in meningitis. The purpose of this study was to evaluate the diagnostic value of NT-proCNP in cerebrospinal fluid (CSF) in patients with meningitis and to compare it with the serum level of CRP and procalcitonin (PCT) in this group of patients. The results were compared to serum levels of CRP, PCT and CSF levels of cytosis, protein and lactate. NT-proCNP levels were statistically significant between the control group and the meningitis groups (p=0.02; R=0.3). We also noted a correlation between the level of NT-proCNP in the CSF of all of the study groups (controls and meningitis patients) and the CSF levels of cytosis (p0.05; R=0.11). These results suggest that NT-proCNP could be a potential marker of meningitis, but it cannot be used to distinguish between the types of meningitis. Copyright © 2015 Elsevier Ireland Ltd.

  18. Helicobacter pylori and non-malignant diseases. (United States)

    Furuta, Takahisa; Delchier, Jean-Charles


    It is well known that Helicobacter pylori infection is associated with many nonmalignant disorders such as gastritis, peptic ulcer, gastroesophageal reflux disease (GERD), gastric polyp, nonsteroidal anti-inflammatory drug (NSAID)/aspirin-induced gastric injury, and functional dyspepsia. In 2008, interesting articles on the association of H. pylori infection with these disorders were presented, some of which intended to reveal the mechanisms of inter-individual differences in response to H. pylori infection, and have demonstrated that genetic differences in host and bacterial factors as well as environmental factors account for these differences. A decline in the occurrence of peptic ulcer related to H. pylori was confirmed. An inverse relationship between H. pylori infection and GERD was also confirmed but the impact of gastric atrophy on the prevention of GERD remained debatable. For NSAID-induced gastric injury, eradication of H. pylori infection has been recommended. During this year, eradication of H. pylori infection was recommended for patients treated with antiplatelet therapy as well as aspirin and NSAID. It was also reported that for patients with functional dyspepsia, eradication of H. pylori offers a modest but significant benefit.

  20. Radiotherapy for non-malignant disorders: state of the art and update of the evidence-based practice guidelines (United States)

    Micke, O; Muecke, R


    Every year in Germany about 50,000 patients are referred and treated by radiotherapy (RT) for “non-malignant disorders”. This highly successful treatment is applied only for specific indications such as preservation or recovery of the quality of life by means of pain reduction or resolution and/or an improvement of formerly impaired physical body function owing to specific disease-related symptoms. Since 1995, German radiation oncologists have treated non-malignant disorders according to national consensus guidelines; these guidelines were updated and further developed over 3 years by implementation of a systematic consensus process to achieve national upgraded and accepted S2e clinical practice guidelines. Throughout this process, international standards of evaluation were implemented. This review summarizes most of the generally accepted indications for the application of RT for non-malignant diseases and presents the special treatment concepts. The following disease groups are addressed: painful degenerative skeletal disorders, hyperproliferative disorders and symptomatic functional disorders. These state of the art guidelines may serve as a platform for daily clinical work; they provide a new starting point for quality assessment, future clinical research, including the design of prospective clinical trials, and outcome research in the underrepresented and less appreciated field of RT for non-malignant disorders.

  3. Spinal astrocytic activation contributes to mechanical allodynia in a rat chemotherapy-induced neuropathic pain model.

    Directory of Open Access Journals (Sweden)

    Xi-Tuan Ji

    Full Text Available Chemotherapy-induced neuropathic pain (CNP is the major dose-limiting factor in cancer chemotherapy. However, the neural mechanisms underlying CNP remain enigmatic. Accumulating evidence implicates the involvement of spinal glia in some neuropathic pain models. In this study, using a vincristine-evoked CNP rat model with obvious mechanical allodynia, we found that spinal astrocyte rather than microglia was dramatically activated. The mechanical allodynia was dose-dependently attenuated by intrathecal administratration of L-α-aminoadipate (astrocytic specific inhibitor; whereas minocycline (microglial specific inhibitor had no such effect, indicating that spinal astrocytic activation contributes to allodynia in CNP rat. Furthermore, oxidative stress mediated the development of spinal astrocytic activation, and activated astrocytes dramatically increased interleukin-1β expression which induced N-methyl-D-aspartic acid receptor (NMDAR phosphorylation in spinal neurons to strengthen pain transmission. Taken together, our findings suggest that spinal activated astrocytes may be a crucial component of the pathophysiology of CNP and "Astrocyte-Cytokine-NMDAR-neuron" pathway may be one detailed neural mechanisms underlying CNP. Thus, inhibiting spinal astrocytic activation may represent a novel therapeutic strategy for treating CNP.

    Serum amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) levels have been proposed as a biomarker of linear growth in healthy children. The usefulness of NT-proCNP in patients with achondroplasia (ACH)/hypochondroplasia (HCH) remains to be elucidated. The objective was to study whether serum NT-proCNP level is a good biomarker for growth in ACH/HCH and other patients of short stature. This was a longitudinal cohort study. Sixteen children with ACH (aged 0·4-4·3 years), six children with HCH (2·7-6·3 years), 23 children with idiopathic short stature (ISS) (2·2-9·0 years), eight short children with GH deficiency (GHD) (2·9-6·8 years) and five short children born small for gestational age (SGA) (2·0-6·6 years). Patients with ACH/HCH received GH treatment for 1 year. Serum NT-proCNP levels and height were measured. NT-proCNP levels positively correlated with height velocity in these short children (P < 0·05, r = 0·27). NT-proCNP levels inversely correlated with age in children with ISS alone (P < 0·01, r = -0·55). Serum NT-proCNP levels in patients with ACH/HCH were increased 3 months following the initiation of GH treatment (P < 0·05). Height SDS gain during GH treatment for 1 year was positively correlated with the changes in NT-proCNP levels after the initiation of GH (P < 0·01, r = 0·72). Serum NT-proCNP levels may be a good biomarker to indicate the effect of GH treatment on growth in patients with ACH/HCH at least in the first year and height velocity in short stature patients. © 2016 John Wiley & Sons Ltd.

  5. Genetic diversity analysis of cyanogenic potential (CNp) of root among improved genotypes of cassava using simple sequence repeat markers. (United States)

    Moyib, O K; Mkumbira, J; Odunola, O A; Dixon, A G


    Cyanogenic potential (CNp) of cassava constitutes a serious problem for over 500 million people who rely on the crop as their main source of calories. Genetic diversity is a key to successful crop improvement for breeding new improved variability for target traits. Forty-three improved genotypes of cassava developed by International Institute of Tropical Agriculture (ITA), Ibadan, were characterized for CNp trait using 35 Simple Sequence.Repeat (SSR) markers. Essential colorimetry picric test was used for evaluation of CNp on a color scale of 1 to 14. The CNp scores obtained ranged from 3 to 9, with a mean score of 5.48 (+/- 0.09) based on Statistical Analysis System (SAS) package. TMS M98/ 0068 (4.0 +/- 0.25) was identified as the best genotype with low CNp while TMS M98/0028 (7.75 +/- 0.25) was the worst. The 43 genotypes were assigned into 7 phenotypic groups based on rank-sum analysis in SAS. Dissimilarity analysis representatives for windows generated a phylogenetic tree with 5 clusters which represented hybridizing groups. Each of the clusters (except 4) contained low CNp genotypes that could be used for improving the high CNp genotypes in the same or near cluster. The scatter plot of the genotypes showed that there was little or no demarcation for phenotypic CNp groupings in the molecular groupings. The result of this study demonstrated that SSR markers are powerful tools for the assessment of genetic variability, and proper identification and selection of parents for genetic improvement of low CNp trait among the IITA cassava collection.

    Francesca eCamera


    Full Text Available Several experimental results published in the literature showed that weak pulsed magnetic fields affected the response of the central nervous system. However, the specific biological mechanisms that regulate the observed behaviors are still unclear and further scientific investigation is required. In this work we performed simulations on a neuronal network model exposed to a specific pulsed magnetic field signal that seems to be very effective in modulating the brain activity: the Complex Neuroelectromagnetic Pulse (CNP. Results show that CNP can silence the neurons of a feed-forward network for signal intensities that depend on the strength of the bias current, the endogenous noise level and the specific waveforms of the pulses.

  8. Bacterial Infections Following Splenectomy for Malignant and Nonmalignant Hematologic Diseases (United States)

    Leone, Giuseppe; Pizzigallo, Eligio


    Splenectomy, while often necessary in otherwise healthy patients after major trauma, finds its primary indication for patients with underlying malignant or nonmalignant hematologic diseases. Indications of splenectomy for hematologic diseases have been reducing in the last few years, due to improved diagnostic and therapeutic tools. In high-income countries, there is a clear decrease over calendar time in the incidence of all indication splenectomy except nonmalignant hematologic diseases. However, splenectomy, even if with different modalities including laparoscopic splenectomy and partial splenectomy, continue to be a current surgical practice both in nonmalignant hematologic diseases, such as Immune Thrombocytopenic Purpura (ITP), Autoimmune Hemolytic Anemia (AIHA), Congenital Hemolytic Anemia such as Spherocytosis, Sickle Cell Anemia and Thalassemia and Malignant Hematological Disease, such as lymphoma. Today millions of people in the world are splenectomized. Splenectomy, independently of its cause, induces an early and late increase in the incidence of venous thromboembolism and infections. Infections remain the most dangerous complication of splenectomy. After splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria. Commonly, the infections strictly correlated to the absence of the spleen or a decreased or absent splenic function are due to encapsulated bacteria that are the most virulent pathogens in this set of patients. Vaccination with polysaccharide and conjugate vaccines again Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis should be performed before the splenectomy. This practice reduces but does not eliminate the occurrence of overwhelming infections due to capsulated bacteria. At present, most of infections found in splenectomized patients are due to Gram

  9. Forest wildfire increases soil microbial biomass C:N:P stoichiometry in long-term effects (United States)

    Zhou, Xuan


    Boreal forest fire strongly influences carbon (C) stock in permafrost soil by thawing permafrost table which accelerated microbe decomposition process. We studied soil microbial biomass stoichiometry in a gradient of four (3 yr, 25 yr, 46 yr and more than 100 yr) ages since fire in Canada boreal forest. Soil microbial biomass (MB) in long-term after fire is significantly higher than in short-term. MB C and nitrogen (N) were mainly dominated by corresponding soil element concentration and inorganic P, while MB phosphorus (P) changes were fully explained by soil N. Fire ages and soil temperature positively increased MB N and P, indicating the negative impact by fire. Microbial C:N:P gradually increased with fire ages from 15:2:1 to 76:6:1 and then drop down to 17:2:1 in the oldest fire ages. The degree of homeostasis of microbial C, N and P are close to 1 indicates non-homoeostasis within microbial elements, while it of C:N:P is close to 8 shows a strong homeostasis within element ratios and proved microbial stoichiometric ratio is not driven by soil element ratios. In conclusion, i) microbial biomass elements highly depends on soil nutrient supply rather than fire ages; ii) wildfire decreased microbial stoichiometry immediate after fire but increased with years after fire (YF) which at least 3 times higher than > 100 fire ages; iii) microbial biomass C, N and P deviated from strict homeostasis but C:N:P ratio reflects stronger homeostasis.

    Full Text Available Elderly population is hospitalized more frequently than young people, and they suffer from more severe diseases that are difficult to diagnose and treat. The present study aimed to investigate the factors affecting mortality in elderly patients hospitalized for nonmalignant reasons. Demographic data, reason for hospitalization, comorbidities, duration of hospital stay, and results of routine blood testing at the time of first hospitalization were obtained from the hospital records of the patients, who were over 65 years of age and hospitalized primarily for nonmalignant reasons. The mean age of 1012 patients included in the study was 77.8 ± 7.6. The most common reason for hospitalization was diabetes mellitus (18.3%. Of the patients, 90.3% had at least a single comorbidity. Whilst 927 (91.6% of the hospitalized patients were discharged, 85 (8.4% died. Comparison of the characteristics of the discharged and dead groups revealed that the dead group was older and had higher rates of poor general status and comorbidity. Differences were observed between the discharged and dead groups in most of the laboratory parameters. Hypoalbuminemia, hypertriglyceridemia, hypopotassemia, hypernatremia, hyperuricemia, and high TSH level were the predictors of mortality. In order to meet the health necessities of the elderly population, it is necessary to well define the patient profiles and to identify the risk factors.

  14. Global biodiversity, stoichiometry and ecosystem function responses to human-induced C-N-P imbalances. (United States)

    Carnicer, Jofre; Sardans, Jordi; Stefanescu, Constantí; Ubach, Andreu; Bartrons, Mireia; Asensio, Dolores; Peñuelas, Josep


    Global change analyses usually consider biodiversity as a global asset that needs to be preserved. Biodiversity is frequently analysed mainly as a response variable affected by diverse environmental drivers. However, recent studies highlight that gradients of biodiversity are associated with gradual changes in the distribution of key dominant functional groups characterized by distinctive traits and stoichiometry, which in turn often define the rates of ecosystem processes and nutrient cycling. Moreover, pervasive links have been reported between biodiversity, food web structure, ecosystem function and species stoichiometry. Here we review current global stoichiometric gradients and how future distributional shifts in key functional groups may in turn influence basic ecosystem functions (production, nutrient cycling, decomposition) and therefore could exert a feedback effect on stoichiometric gradients. The C-N-P stoichiometry of most primary producers (phytoplankton, algae, plants) has been linked to functional trait continua (i.e. to major axes of phenotypic variation observed in inter-specific analyses of multiple traits). In contrast, the C-N-P stoichiometry of higher-level consumers remains less precisely quantified in many taxonomic groups. We show that significant links are observed between trait continua across trophic levels. In spite of recent advances, the future reciprocal feedbacks between key functional groups, biodiversity and ecosystem functions remain largely uncertain. The reported evidence, however, highlights the key role of stoichiometric traits and suggests the need of a progressive shift towards an ecosystemic and stoichiometric perspective in global biodiversity analyses.

    Li Dongsheng


    CNP1500 is a four-loop PWR nuclear power plant with light water as moderator and coolant. The reactor core is composed of 205 AFA-3GXL fuel assemblies. The active core height at cold is 426.4 cm and equivalent diameter is 347.0 cm. The reactor thermal output is 4250 MW, and average linear power density is 179.5 W/cm. The cycle length of equilibrium cycle core is 470 equivalent full power days. For all cycles, the moderator temperature coefficients at all conditions are negative values, the nuclear enthalpy rise factors F ΔH at hot full power, all control rods out and equilibrium xenon are less than the limit value, the maximum discharge assembly burnup is less 55000 MW·d/tU, and the shutdown margin values at the end of life meet design criteria. The low-leakage core loading reduces radiation damage on pressure vessel and is beneficial to prolong use lifetime of it. The in-core fuel management design scheme and main calculation results for CNP1500 nuclear power plant are presented. (author)

  16. A novel peptide from the ACEI/BPP-CNP precursor in the venom of Crotalus durissus collilineatus. (United States)

    Higuchi, Shigesada; Murayama, Nobuhiro; Saguchi, Ken-ichi; Ohi, Hiroaki; Fujita, Yoshiaki; da Silva, Nelson Jorge; de Siqueira, Rodrigo José Bezerra; Lahlou, Saad; Aird, Steven D


    In crotaline venoms, angiotensin-converting enzyme inhibitors [ACEIs, also known as bradykinin potentiating peptides (BPPs)], are products of a gene coding for an ACEI/BPP-C-type natriuretic peptide (CNP) precursor. In the genes from Bothrops jararaca and Gloydius blomhoffii, ACEI/BPP sequences are repeated. Sequencing of a cDNA clone from venom glands of Crotalus durissus collilineatus showed that two ACEIs/BPPs are located together at the N-terminus, but without repeats. An additional sequence for CNP was unexpectedly found at the C-terminus. Homologous genes for the ACEI/BPP-CNP precursor suggest that most crotaline venoms contain both ACEIs/BPPs and CNP. The sequence of ACEIs/BPPs is separated from the CNP sequence by a long spacer sequence. Previously, there was no evidence that this spacer actually coded any expressed peptides. Aird and Kaiser (1986, unpublished) previously isolated and sequenced a peptide of 11 residues (TPPAGPDVGPR) from Crotalus viridis viridis venom. In the present study, analysis of the cDNA clone from C. d. collilineatus revealed a nearly identical sequence in the ACEI/BPP-CNP spacer. Fractionation of the crude venom by reverse phase HPLC (C(18)), and analysis of the fractions by mass spectrometry (MS) indicated a component of 1020.5 Da. Amino acid sequencing by MS/MS confirmed that C. d. collilineatus venom contains the peptide TPPAGPDGGPR. Its high proline content and paired proline residues are typical of venom hypotensive peptides, although it lacks the usual N-terminal pyroglutamate. It has no demonstrable hypotensive activity when injected intravenously in rats; however, its occurrence in the venoms of dissimilar species suggests that its presence is not accidental. Evidence suggests that these novel toxins probably activate anaphylatoxin C3a receptors.

    Smith, H.S.; Lan, S.; Ceriani, R.; Hackett, A.J.; Stampfer, M.R.


    We have developed a method for clonal growth of human mammary epithelial cells of both nonmalignant and malignant origin. Plating efficiencies of 1 to 50% were obtained by seeding second-passage mammary epithelial cells on fibroblast feeder layers in an enriched medium composed of various hormones and growth factors, as well as conditioned media from three specific human cell lines. Single mammary epithelial cells seeded sparsely onto the fibroblasts underwent at least eight population doublings to form large, readily visible colonies. Optimal colony formation required both feeder cells and the enriched medium. Epithelial colonies containing at least 16 cells were visible 5 days postseeding, and these colonies continued to grow progressively. Plating efficiency and colony size were similar on ultraviolet-irradiated or nonirradiated fibroblasts. The number of colonies formed was proportional to the number of epithelial cells plated. The colonies were identified as epithelial by the presence of human mammary epithelial antigens

  2. Determinants of hematology-oncology trainees' postfellowship career pathways with a focus on nonmalignant hematology (United States)

    Jenkins, Sarah; Mikhael, Joseph; Gitlin, Scott D.


    Nonmalignant hematologic conditions are extremely prevalent and contribute significantly to the global burden of disease. The US health care system may soon face a shortage of specialists in nonmalignant hematology. We sought to identify factors that lead hematology-oncology fellows to pursue (or not to pursue) careers in nonmalignant hematology. Cross-sectional, web-based survey distributed to 149 graduates of a hematology-oncology fellowship program at a large academic medical center between 1998 and 2016. Eighty-six out of 149 graduates responded (57.7%); most (59 [68.6%]) practice at an academic medical center. Respondents spend a mean of 61% of their time in clinical practice, 23.7% conducting research, 5.2% in education, and 5.2% in administration. Those in clinical practice spend a mean of 52.1% of their time in solid tumor oncology, 37.5% in hematologic malignancies, and 10% in nonmalignant hematology; only 1 spent >50% of time practicing nonmalignant hematology. Factors most significantly affecting choice of patient population included clinical experience during fellowship and intellectual stimulation of the patient population/disease type. Factors that could have most significantly influenced a decision to spend more time in nonmalignant hematology included increased exposure/access to role models and mentors and opportunities for better career growth/advancement. Fellowship graduates spend >50% of their time in clinical practice, but almost none spend a significant amount of time practicing nonmalignant hematology. Given the growing number of patients with nonmalignant hematologic conditions and a possible future provider shortage, medical trainees should be encouraged to pursue careers in nonmalignant hematology.

    Full Text Available Human height is a highly heritable trait considered as an important factor for health. There has been limited success in identifying the genetic factors underlying height variation. We aim to identify sequence variants associated with adult height by a genome-wide association study of copy number variants (CNVs in Chinese.Genome-wide CNV association analyses were conducted in 1,625 unrelated Chinese adults and sex specific subgroup for height variation, respectively. Height was measured with a stadiometer. Affymetrix SNP6.0 genotyping platform was used to identify copy number polymorphisms (CNPs. We constructed a genomic map containing 1,009 CNPs in Chinese individuals and performed a genome-wide association study of CNPs with height.We detected 10 significant association signals for height (p<0.05 in the whole population, 9 and 11 association signals for Chinese female and male population, respectively. A copy number polymorphism (CNP12587, chr18:54081842-54086942, p = 2.41 × 10(-4 was found to be significantly associated with height variation in Chinese females even after strict Bonferroni correction (p = 0.048. Confirmatory real time PCR experiments lent further support for CNV validation. Compared to female subjects with two copies of the CNP, carriers of three copies had an average of 8.1% decrease in height. An important candidate gene, ubiquitin-protein ligase NEDD4-like (NEDD4L, was detected at this region, which plays important roles in bone metabolism by binding to bone formation regulators.Our findings suggest the important genetic variants underlying height variation in Chinese.

  4. The hazards of using ionising radiation for non-malignant conditions - a case study

    Morton, Tracy


    A case study is presented in which a patient received low dose radiotherapy at seven months for a non-malignant cavernous haemangioma on the upper chest. She subsequently developed three separate malignancies before the age of 40 years: a thyroid carcinoma, a breast carcinoma and a basal cell carcinoma of the skin on the upper chest. This case illustrates the hazards of using ionizing radiation for the treatment of non-malignant conditions. (U.K.)

  5. Recurrent, nonmalignant tracheoesophageal fistulas and the need for surgical improvisation. (United States)

    Altorjay, Aron; Mucs, Mihály; Rüll, Miklós; Tihanyi, Zoltán; Hamvas, Balázs; Madácsy, László; Paál, Balázs


    Despite the many recent advances in thoracic surgery, the management of patients with recurrent, nonmalignant tracheoesophageal fistulas remains problematic, controversial, and challenging. Between 1998 and 2008, we treated 8 patients with RTEF. Closure of the original tracheoesophageal fistula had been attempted once in 5 patients, twice in 2 patients, and 4 times in 1 patient, all in different institutions. Four cases necessitated right posterolateral thoracotomy and cervical exposure, 2 cases cervical and abdominal incision, and 1 case right posterolateral thoracotomy, with abdominal and cervical exposure. With the exception of the 2 patients whose excluded esophagus was used to substitute for the trachea membranous wall, the damaged tracheal segment was removed. In general, a pedicled mediastinal pleural flap was pulled into the neck to increase the safety of the tracheal anastomosis formed with the trachea, and (or) to separate the suture lines of the two organs. A single intervention was sufficient for all 8 patients: no reoperation was necessary, and there was no perioperative mortality. Transient reflux, abdominal distention, and dyspnea in response to forced physical exertion occurred in 1 case each. Only 1 patient subsequently takes medication regularly for reflux disease. Separation initiated from the tracheal bifurcation, a pedicled mediastinal pleural flap pulled into the neck, a tracheal anastomosis sewn onto the cricoid cartilage with avoidance of its posterolateral elbow, a shaped Dumon stent (Novatech, Plan de Grasse, France) with an individually fenestrated tracheostomy cannula, and endoscopy-assisted, transhiatal vagal-preserving esophageal exclusion all served as successful elements of our surgical procedures. 2010 The Society of Thoracic Surgeons.

  6. Effect of Discontinuous Ultrasonic Treatment on Mechanical Properties and Microstructure of Cast Al413-SiCnp Nanocomposites

    Directory of Open Access Journals (Sweden)

    M.R. Dehnavi


    Full Text Available Effects of discontinuous ultrasonic treatment on the microstructure, nanoparticle distribution, and mechanical properties of cast Al413-SiCnp nanocomposites were studied. The results showed that discontinuous ultrasonic treatment was more effective in improving the mechanical properties of the cast nanocomposites than the equally timed continuous treatment. The yield and ultimate tensile strengths of Al413-2%SiCnp nanocomposites discontinuously treated for two 20 minute periods increased by about 126% and 100% compared to those of the monolithic sample, respectively. These improvements were about 107% and 94% for the nanocomposites continuously treated for a single 40 minute period. The improvement in the mechanical properties was associated with severe refinement of the microstructure, removal of the remaining gas layers on the particles surfaces, more effective fragmentation of the remaining agglomerates as well as improved wettability and distribution of the reinforcing particles during the first stage of solidification.

  7. Rapid top-down regulation of plant C:N:P stoichiometry by grasshoppers in an Inner Mongolia grassland ecosystem. (United States)

    Zhang, Guangming; Han, Xingguo; Elser, James J


    Understanding how food web interactions alter the processing of limiting nutrient elements is an important goal of ecosystem ecology. An experiment manipulating densities of the grasshopper Oedaleus asiaticus was performed to assess top-down effects of grasshoppers on C:N:P stoichiometry of plants and soil in a grassland ecosystem in Inner Mongolia (China). With increased grasshopper feeding, plant biomass declined fourfold, litter abundance increased 30%, and the plant community became dominated by non-host plant taxa. Plant stoichiometric response depended on whether or not the plant was a grasshopper host food species: C:N and C:P ratios increased with increasing grasshopper density (GD) for host plants but decreased in non-host plants. These data suggest either a direct transfer of grasshopper-recycled nutrients from host to non-host plants or a release of non-host plants from nutrient competition with heavily grazed host plants. Litterfall C:N and C:P decreased across moderate levels of grasshopper density but no effects on C:N:P stoichiometry in the surface soil were observed, possibly due to the short experimental period. Our observations of divergent C:N:P stoichiometric response among plant species highlight the important role of grasshopper herbivory in regulating plant community structure and nutrient cycling in grassland ecosystems.

  8. Reduced ability of C-type natriuretic peptide (CNP) to activate natriuretic peptide receptor B (NPR-B) causes dwarfism in lbab−/− mice (United States)

    Yoder, Andrea R.; Kruse, Andrew C.; Earhart, Cathleen A.; Ohlendorf, Douglas H.; Potter, Lincoln R.


    C-type natriuretic peptide (CNP) stimulates endochondrial ossification by activating the transmembrane guanylyl cyclase, natriuretic peptide receptor-B (NPR-B). Recently, a spontaneous autosomal recessive mutation that causes severe dwarfism in mice was identified. The mutant, called long bone abnormality (lbab), contains a single point mutation that converts an arginine to a glycine in a conserved coding region of the CNP gene, but how this mutation affects CNP activity has not been reported. Here, we determined that thirty to greater than one hundred-fold more CNPlbab was required to activate NPR-B as compared to wild-type CNP in whole cell cGMP elevation and membrane guanylyl cyclase assays. The reduced ability of CNPlbab to activate NPR-B was explained, at least in part, by decreased binding since ten-fold more CNPlbab than wild-type CNP was required to compete with [125I][Tyr0]CNP for receptor binding. Molecular modeling suggested that the conserved arginine is critical for binding to an equally conserved acidic pocket in NPR-B. These results indicate that reduced binding to and activation of NPR-B causes dwarfism in lbab−/− mice. PMID:18554750

  9. Evidence of Physiotherapy Interventions for Patients with Chronic Neck Pain: A Systematic Review of Randomised Controlled Trials (United States)

    Damgaard, Pia; Bartels, Else Marie; Ris, Inge; Christensen, Robin; Juul-Kristensen, Birgit


    Chronic neck pain (CNP) is common and costly, and the effect of physiotherapeutic interventions on the condition is unclear. We reviewed the literature for evidence of effect of physiotherapy interventions on patients with CNP. Five bibliographic databases (MEDLINE, EMBASE, CINAHL, Cochrane Library, and PEDro) were systematically searched. Randomised, placebo and active-treatment-controlled trials including physiotherapy interventions for adults with CNP were selected. Data were extracted primary outcome was pain. Risk of bias was appraised. Effect of an intervention was assessed, weighted to risk of bias. 42 trials reporting on randomised comparisons of various physiotherapy interventions and control conditions were eligible for inclusion involving 3919 patients with CNP. Out of these, 23 were unclear or at high risk of bias, and their results were considered moderate- or low-quality evidence. Nineteen were at low risk of bias, and here eight trials found effect on pain of a physiotherapy intervention. Only exercise therapy, focusing on strength and endurance training, and multimodal physiotherapy, cognitive-behavioural interventions, massage, manipulations, laser therapy, and to some extent also TNS appear to have an effect on CNP. However, sufficient evidence for application of a specific physiotherapy modality or aiming at a specific patient subgroup is not available. PMID:27335877

    Lauche, Romy; Cramer, Holger; Hohmann, Claudia; Choi, Kyung-Eun; Rampp, Thomas; Saha, Felix Joyonto; Musial, Frauke; Langhorst, Jost; Dobos, Gustav


    Introduction. Cupping has been used since antiquity in the treatment of pain conditions. In this pilot study, we investigated the effect of traditional cupping therapy on chronic nonspecific neck pain (CNP) and mechanical sensory thresholds. Methods. Fifty CNP patients were randomly assigned to treatment (TG, n = 25) or waiting list control group (WL, n = 25). TG received a single cupping treatment. Pain at rest (PR), pain related to movement (PM), quality of life (SF-36), Neck Disability Index (NDI), mechanical detection (MDT), vibration detection (MDT), and pressure pain thresholds (PPT) were measured before and three days after a single cupping treatment. Patients also kept a pain and medication diary (PaDi, MeDi) during the study. Results. Baseline characteristics were similar in the two groups. After cupping TG reported significantly less pain (PR: −17.9 mm VAS, 95%CI −29.2 to −6.6; PM: −19.7, 95%CI −32.2 to −7.2; PaDi: −1.5 points on NRS, 95%CI −2.5 to −0.4; all P cupping might be an effective treatment for improving pain, quality of life, and hyperalgesia in CNP.

  11. Economic burden of non-malignant blood disorders across Europe: a population-based cost study. (United States)

    Luengo-Fernandez, Ramon; Burns, Richeal; Leal, Jose


    Blood disorders comprise a wide range of diseases including anaemia, malignant blood disorders, and haemorrhagic disorders. Although they are a common cause of disease, no systematic cost-of-illness studies have been done to assess the economic effect of non-malignant blood disorders in Europe. We aimed to assess the economic burden of non-malignant blood disorders across the 28 countries of the European Union (EU), Iceland, Norway, and Switzerland. Non-malignant blood disorder-related costs (WHO International Classification of Diseases, 10th revision [ICD] D50-89) were estimated for 28 EU countries, Iceland, Norway, and Switzerland for 2012. Country-specific costs were estimated with aggregate data on morbidity, mortality, and health-care resource use obtained from international and national sources. Health-care costs were estimated from expenditure on primary care, outpatient care, emergency care, hospital inpatient care, and drugs. Costs of informal care and productivity losses due to morbidity and early death were also included. To these costs we added those due to malignant blood disorders (ICD-10 C81-96 and D47) as estimated in a Burns and colleagues' companion Article to obtain the total costs of blood disorders. Non-malignant disorders of the blood cost the 31 European countries €11 billion in 2012. Health-care costs accounted for €8 billion (75% of total costs), productivity losses for €2 billion (19%), and informal care for less than €1 billion (6%). Averaged across the European population studied, non-malignant disorders of the blood represented an annual health-care cost of €159 per ten citizens. Combining malignant and non-malignant blood disorders, the total cost of blood disorders was €23 billion in 2012. Our study highlights the economic burden that non-malignant blood disorders place on European health-care systems and societies. Our study also shows that blood disorder costs were evenly distributed between malignant and non-malignant

    , incidence and prevalence of addiction in opioid treated pain patients, screening tools for assessing opioid addiction in chronic pain patients and recommendations regarding addiction problems in national and international guidelines for opioid treatment in cancer patients and chronic non-malignant pain...... patients. The review indicates that the prevalence of addiction varied from 0% up to 50% in chronic non-malignant pain patients, and from 0% to 7.7% in cancer patients depending of the subpopulation studied and the criteria used. The risk of addiction has to be considered when initiating long-term opioid...... treatment as addiction may result in poor pain control. Several screening tools were identified, but only a few were thoroughly validated with respect to validity and reliability. Most of the identified guidelines mention addiction as a potential problem.

  13. Transient Cnp expression by early progenitors causes Cre-Lox-based reporter lines to map profoundly different fates. (United States)

    Tognatta, Reshmi; Sun, Wenjing; Goebbels, Sandra; Nave, Klaus-Armin; Nishiyama, Akiko; Schoch, Susanne; Dimou, Leda; Dietrich, Dirk


    NG2 expressing oligodendroglial precursor cells are ubiquitous in the central nervous system and the only cell type cycling throughout life. Previous fate mapping studies have remained inconsistent regarding the question whether NG2 cells are capable of generating certain types of neurons. Here, we use CNP-Cre mice to map the fate of a sub-population of NG2 cells assumed to be close to differentiation. When crossing these mice with the ROSA26/YFP Cre-reporter line we discovered large numbers of reporter-expressing pyramidal neurons in the piriform and dorsal cortex. In contrast, when using Z/EG reporter mice to track the fate of Cnp-expressing NG2 cells only oligodendroglial cells were found reporter positive. Using BrdU-based birth dating protocols and inducible NG2CreER:ROSA26/YFP mice we show that YFP positive neurons are generated from radial glial cells and that these radial glial cells display temporary and low level activity of certain oligodendroglial genes sufficient to recombine the Cre-inducible reporter gene in ROSA26/YFP but not in Z/EG mice. Taken together, we did not obtain evidence for generation of neurons from NG2 cells. Our results suggest that with an appropriate reporter system Cnp activity can be used to define a proliferative subpopulation of NG2 cells committed to generate oligodendrocytes. However, the strikingly different results obtained from ROSA26/YFP versus Z/EG mice demonstrate that the choice of Cre-reporter line can be of crucial importance for fate mapping studies and other applications of the Cre-lox technology.

    Nadine Gelbrich


    Full Text Available Objective. Cytokines and chemokines are widely involved in cancer cell progression and thus represent promising candidate factors for new biomarkers. Methods. Four renal cell cancer (RCC cell lines (Caki-1, 786-O, RCC4, and A498 and a nonmalignant renal cell line (RC-124 were examined with respect to their proliferation. The cytokine and chemokine expression pattern was examined by a DNA array (Human Cytokines & Chemokines RT2 Profiler PCR Array; Qiagen, Hilden, Germany, and expression profiles were compared. Results. Caki-1 and 786-O cells exhibited significantly increased proliferation rates, whereas RCC4 and A498 cells demonstrated attenuated proliferation, compared to nonmalignant RC-124 cells. Expression analysis revealed 52 cytokines and chemokines primarily involved in proliferation and inflammation and differentially expressed not only in malignant and nonmalignant renal cells but also in the four RCC cell lines. Conclusion. This is the first study examining the expression of 84 cytokines and chemokines in four RCC cell lines compared to that in a nonmalignant renal cell line. VEGFA, NODAL, and BMP6 correlated with RCC cell line proliferation and, thus, may represent putative clinical biomarkers for RCC progression as well as for RCC diagnosis and prognosis.

  15. Pain management in older adults. (United States)

    Tracy, Bridget; Sean Morrison, R


    Chronic pain is prevalent among older adults but is underrecognized and undertreated. The approach to pain assessment and management in older adults requires an understanding of the physiology of aging, validated assessment tools, and common pain presentations among older adults. To identify the overall principles of pain management in older adults with a specific focus on common painful conditions and approaches to pharmacologic treatment. We searched PubMed for common pain presentations in older adults with heart failure, end-stage renal disease, dementia, frailty, and cancer. We also reviewed guidelines for pain management. Our review encompassed 2 guidelines, 10 original studies, and 22 review articles published from 2000 to the present. This review does not discuss nonpharmacologic treatments of pain. Clinical guidelines support the use of opioids in persistent nonmalignant pain. Opioids should be used in patients with moderate or severe pain or pain not otherwise controlled but with careful attention to potential toxic effects and half-life. In addition, clinical practice guidelines recommend use of oral nonsteroidal anti-inflammatory drugs with extreme caution and for defined, limited periods. An understanding of the basics of pain pathophysiology, assessment, pharmacologic management, and a familiarity with common pain presentations will allow clinicians to effectively manage pain for older adults. © 2013 Elsevier HS Journals, Inc.

    Full Text Available The purpose of this study was to investigate health-related quality of life (HRQOL and associated factors in patients with chronic neck pain (CNP. The HRQOL of patients with CNP was assessed by the Short Form-36 questionnaire in this cross-sectional study. To evaluate the psychological factors related to HRQOL, the Eysenck Personality Questionnaire, Chinese Health Questionnaire, and Beck Anxiety Inventory were used. The scores for the eight subscales of Short Form-36 were all lower than the Taiwanese age-matched normative values (p < 0.001. The two most strongly affected subscales were the role–physical subscale and the bodily pain sub-scale; both scores were below half the score of the age-/sex-matched normative values. The physical components summary score, a summary measure, was moderately correlated with age (ρ = −0.43, education level (ρ = 0.37 and Beck Anxiety Inventory score (ρ = −0.36. The mental components summary score was moderately to highly correlated with the Chinese Health Questionnaire score (ρ = −0.72, the neuroticism domain of Eysenck Personality Questionnaire (ρ = −0.52 and Beck Anxiety Inventory score (ρ = −0.41. The HRQOL of patients with CNP was worse than that of normal subjects across all domains. Furthermore, patients with a neurotic personality, minor psychiatric morbidity and higher anxiety status showed poor mental health, as measured by the Short Form-36. We found that patients with CNP had multiple physical and mental health problems in terms of. The mental health of patients with CNP was strongly associated with various psychological factors. Comprehensive assessment of the physical and mental functioning of patients with CNP can improve the management and care of these patients.

  17. Chronic female pelvic pain

    Gaurab Maitra


    Full Text Available Chronic pelvic pain (CPP is defined as nonmalignant pain perceived in the structures related to the pelvis that has been present for more than 6 months or a non acute pain mechanism of shorter duration. Pain in the pelvic region can arise from musculoskeletal, gynaecological, urologic, gastrointestinal and or neurologic conditions. Key gynaecological conditions that contribute to CPP include pelvic inflammatory disease (PID, endometriosis, adnexa pathologies (ovarian cysts, ovarian remnant syndrome, uterine pathologies (leiomyoma, adenomyosis and pelvic girdle pain associated with pregnancy. Several major and minor sexually transmitted diseases (STD can cause pelvic and vulvar pain. A common painful condition of the urinary system is Interstitial cystitis(IC. A second urologic condition that can lead to development of CPP is urethral syndrome. Irritable bowel syndrome (IBS is associated with dysmenorrhoea in 60% of cases. Other bowel conditions contributing to pelvic pain include diverticular disease,Crohn′s disease ulcerative colitis and chronic appendicitis. Musculoskeletal pathologies that can cause pelvic pain include sacroiliac joint (SIJ dysfunction, symphysis pubis and sacro-coccygeal joint dysfunction, coccyx injury or malposition and neuropathic structures in the lower thoracic, lumbar and sacral plexus. Prolonged pelvic girdle pain, lasting more than 6 months postpartum is estimated in 3% to 30% of women. Nerve irritation or entrapment as a cause of pelvic pain can be related to injury of the upper lumbar segments giving rise to irritation of the sensory nerves to the ventral trunk or from direct trauma from abdominal incisions or retractors used during abdominal surgical procedures. Afflictions of the iliohypogastric, ilioinguinal, genitofemoral, pudendal and obturator nerves are of greatest concern in patients with pelvic pain. Patient education about the disease and treatment involved is paramount. A knowledge of the differential

    The integral measurement of the $^{12}$C(n,p)$^{12}$B reaction was performed at the neutron time of flight facility n_TOF at CERN. The total number of $^{12}$B nuclei produced per neutron pulse of the n_TOF beam was determined using the activation technique in combination with a time of flight technique. The cross section is integrated over the n_TOF neutron energy spectrum from reaction threshold at 13.6 MeV to 10 GeV. Having been measured up to 1 GeV on basis of the $^{235}$U(n,f) reaction, the neutron energy spectrum above 200 MeV has been reevaluated due to the recent extension of the cross section reference for this particular reaction, which is otherwise considered a standard up to 200 MeV. The results from the dedicated GEANT4 simulations have been used to evaluate the neutron flux from 1 GeV up to 10 GeV. The experimental results related to the $^{12}$C(n,p)$^{12}$B reaction are compared with the evaluated cross sections from major libraries and with the predictions of different GEANT4 models, which m...

  20. Clinical significance of determination of serum NSE and plasma ET, IGF-II, CNP levels in patients with acute brain injury

    International Nuclear Information System (INIS)

    Chen Bo


    Objective: To investigate the clinical significance of changes of plasma ET, IGF-II, CNP and serum NSE contents in patients with acute brain injury. Methods: Serum contents of neuron specific enolase (NSE) were measured with chemiluminescence immunoassay and plasma endothelin (ET), insulin-like growth factor-II (IGF-II) and C-type natriuretic peptide (CNP) were measured with radioimmunoassay in 30 patients with acute brain injury and 35 controls. Results: Serum contents of NSE and plasma IGF-II, CNP were not much different in patients with mild brain injury from those in controls (P >0.05), but plasma contents of ET were already significantly higher in patients with mild brain injury than those in controls(P < 0.01). The serum NSE and plasma ET levels in patients with moderate and severe brain injury were significantly higher than those in patients with mild brain injury and controls (P < 0.01). Decrease of plasma levels of IGF-II and CNP was not significant in patients with mild brain injury (vs controls). However, the plasma levels of IGF-II and CNP were significantly lower in patients with moderate and severe brain injury than those in patients with mild brain injury and controls (P <0.01). As a whole, the magnitude of changes of these parameters was proportional to the severity of the injury. Conclusion: Changes of serum NSE and plasma IGF-II, ET and CNP levels were closely related to the pathological process of brain injury. Determination of these parameters was of clinical importance for evaluation of the severity of injury and outcome prediction. (authors)

  1. Reimbursement of analgesics for chronic pain. (United States)

    Pedersen, Line; Hansen, Anneli Borge; Svendsen, Kristian; Skurtveit, Svetlana; Borchgrevink, Petter C; Fredheim, Olav Magnus S


    The prevalence of chronic non-malignant pain in Norway is between 24% and 30%. The proportion of the population using opioids for non-malignant pain on a long-term basis is around 1%. The purpose of our study was to investigate how many were prescribed analgesics on reimbursable prescription under reimbursement code -71 (chronic non-malignant pain) in 2009 and 2010, which analgesics were prescribed and whether prescribing practices were in accordance with national guidelines. We retrieved pseudonymised data from the National Prescription Database on all those who received drugs with reimbursement code -71 in 2009 and 2010. The data contain information on drug, dosage, formulation, reimbursement code and date of issue. 90,731 patients received reimbursement for drugs indicated for chronic non-malignant pain in 2010. Of these, 6,875 were given opioids, 33,242 received paracetamol, 25,865 non-steroid inflammatory drugs (NSAIDs), 20,654 amitryptiline and 16,507 gabapentin. Oxycodone was the most frequently prescribed opioid, followed by buprenorphine, tramadol and codeine/paracetamol. Of those who were prescribed opioids, 4,047 (59%) received mainly slow-release opioids, 2,631 (38%) also received benzodiazepines and 2,418 (35%) received benzodiazepine-like sleep medications. The number of patients who received analgesics and opioids on reimbursable prescriptions was low compared to the proportion of the population with chronic pain and the proportion using opioids long-term. 38% of those reimbursed for opioids also used benzodiazepines, which is contrary to official Norwegian guidelines.

  3. Nonmalignant T cells stimulate growth of T-cell lymphoma cells in the presence of bacterial toxins

    DEFF Research Database (Denmark)

    Woetmann, Anders; Lovato, Paola; Eriksen, Karsten W


    Bacterial toxins including staphylococcal enterotoxins (SEs) have been implicated in the pathogenesis of cutaneous T-cell lymphomas (CTCLs). Here, we investigate SE-mediated interactions between nonmalignant T cells and malignant T-cell lines established from skin and blood of CTCL patients....... The malignant CTCL cells express MHC class II molecules that are high-affinity receptors for SE. Although treatment with SE has no direct effect on the growth of the malignant CTCL cells, the SE-treated CTCL cells induce vigorous proliferation of the SE-responsive nonmalignant T cells. In turn, the nonmalignant...... T cells enhance proliferation of the malignant cells in an SE- and MHC class II-dependent manner. Furthermore, SE and, in addition, alloantigen presentation by malignant CTCL cells to irradiated nonmalignant CD4(+) T-cell lines also enhance proliferation of the malignant cells. The growth...

  5. Lipid peroxidation and antioxidants status in human malignant and non-malignant thyroid tumours. (United States)

    Stanley, J A; Neelamohan, R; Suthagar, E; Vengatesh, G; Jayakumar, J; Chandrasekaran, M; Banu, S K; Aruldhas, M M


    Thyroid epithelial cells produce moderate amounts of reactive oxygen species that are physiologically required for thyroid hormone synthesis. Nevertheless, when they are produced in excessive amounts, they may become toxic. The present study is aimed to compare the lipid peroxidation (LPO), antioxidant enzymes - superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and non-protein thiols (reduced glutathione (GSH)) in human thyroid tissues with malignant and non-malignant disorders. The study used human thyroid tissues and blood samples from 157 women (147 diseased and 10 normal). Thyroid hormones, oxidative stress markers and antioxidants were estimated by standard methods. LPO significantly increased in most of the papillary thyroid carcinoma (PTC: 82.9%) and follicular thyroid adenoma (FTA: 72.9%) tissues, whilst in a majority of nodular goitre (69.2%) and Hashimoto's thyroiditis (HT: 73.7%) thyroid tissues, it remained unaltered. GSH increased in PTC (55.3%), remained unaltered in FTA (97.3%) and all other goiter samples studied. SOD increased in PTC (51.1%) and all other malignant thyroid tissues studied. CAT remained unaltered in PTC (95.7%), FTA (97.3%) and all other non-malignant samples (HT, MNG, TMNG) studied. GPx increased in PTC (63.8%), all other malignant thyroid tissues and remained unaltered in many of the FTA (91.9%) tissues and all other non-malignant samples (HT, MNG, TMNG) studied. In the case of non-malignant thyroid tumours, the oxidant-antioxidant balance was undisturbed, whilst in malignant tumours the balance was altered, and the change in r value observed in the LPO and SOD pairs between normal and PTC tissues and also in many pairs with multi-nodular goitre (MNG)/toxic MNG tissues may be used as a marker to differentiate/detect different malignant/non-malignant thyroid tumours. © The Author(s) 2015.

  6. Extracellular vesicle-mediated phenotype switching in malignant and non-malignant colon cells

    Mulvey, Hillary E.; Chang, Audrey; Adler, Jason; Del Tatto, Michael; Perez, Kimberly; Quesenberry, Peter J.; Chatterjee, Devasis


    Extracellular vesicles (EVs) are secreted from many cells, carrying cargoes including proteins and nucleic acids. Research has shown that EVs play a role in a variety of biological processes including immunity, bone formation and recently they have been implicated in promotion of a metastatic phenotype. EVs were isolated from HCT116 colon cancer cells, 1459 non-malignant colon fibroblast cells, and tumor and normal colon tissue from a patient sample. Co-cultures were performed with 1459 cells and malignant vesicles, as well as HCT116 cells and non-malignant vesicles. Malignant phenotype was measured using soft agar colony formation assay. Co-cultures were also analyzed for protein levels using mass spectrometry. The importance of 14-3-3 zeta/delta in transfer of malignant phenotype was explored using siRNA. Additionally, luciferase reporter assay was used to measure the transcriptional activity of NF-κB. This study demonstrates the ability of EVs derived from malignant colon cancer cell line and malignant patient tissue to induce the malignant phenotype in non-malignant colon cells. Similarly, EVs derived from non-malignant colon cell lines and normal patient tissue reversed the malignant phenotype of HCT116 cells. Cells expressing an EV-induced malignant phenotype showed increased transcriptional activity of NF-κB which was inhibited by the NF--κB inhibitor, BAY117082. We also demonstrate that knock down of 14-3-3 zeta/delta reduced anchorage-independent growth of HCT116 cells and 1459 cells co-cultured with HCT derived EVs. Evidence of EV-mediated induction of malignant phenotype, and reversal of malignant phenotype, provides rational basis for further study of the role of EVs in tumorigenesis. Identification of 14-3-3 zeta/delta as up-regulated in malignancy suggests its potential as a putative drug target for the treatment of colorectal cancer

  7. The Role of Ventral Tegmental Area Gamma-Aminobutyric Acid in Chronic Neuropathic Pain after Spinal Cord Injury in Rats. (United States)

    Ko, Moon Yi; Jang, Eun Young; Lee, June Yeon; Kim, Soo Phil; Whang, Sung Hun; Lee, Bong Hyo; Kim, Hee Young; Yang, Chae Ha; Cho, Hee Jung; Gwak, Young S


    Spinal cord injury (SCI) frequently results in chronic neuropathic pain (CNP). However, the understanding of brain neural circuits in CNP modulation is unclear. The present study examined the changes of ventral tegmental area (VTA) putative GABAergic and dopaminergic neuronal activity with CNP attenuation in rats. SCI was established by T10 clip compression injury (35 g, 1 min) in rats, and neuropathic pain behaviors, in vivo extracellular single-cell recording of putative VTA gamma-aminobutyric acid (GABA)/dopamine neurons, extracellular GABA level, glutamic acid decarboxylase (GAD), and vesicular GABA transporters (VGATs) were measured in the VTA, respectively. The results revealed that extracellular GABA level was significantly increased in the CNP group (50.5 ± 18.9 nM) compared to the sham control group (10.2 ± 1.7 nM). In addition, expression of GAD 65/67 , c-Fos, and VGAT exhibited significant increases in the SCI groups compared to the sham control group. With regard to neuropathic pain behaviors, spontaneous pain measured by ultrasound vocalizations (USVs) and evoked pain measured by paw withdrawal thresholds showed significant alteration, which was reversed by intravenous (i.v.) administration of morphine (0.5-5.0 mg/kg). With regard to in vivo electrophysiology, VTA putative GABAergic neuronal activity (13.6 ± 1.7 spikes/sec) and putative dopaminergic neuronal activity (2.4 ± 0.8 spikes/sec) were increased and decreased, respectively, in the SCI group compared to the sham control group. These neuronal activities were reversed by i.v. administration of morphine. The present study suggests that chronic increase of GABAergic neuronal activity suppresses dopaminergic neuronal activity in the VTA and is responsible for negative emotion and motivation for attenuation of SCI-induced CNP.

  8. Meta-analysis of transcutaneous electrical nerve stimulation for relief of spinal pain. (United States)

    Resende, L; Merriwether, E; Rampazo, É P; Dailey, D; Embree, J; Deberg, J; Liebano, R E; Sluka, K A


    We conducted a systematic review and meta-analysis analysing the existing data on transcutaneous electrical nerve stimulation (TENS) or interferential current (IFC) for chronic low back pain (CLBP) and/or neck pain (CNP) taking into account intensity and timing of stimulation, examining pain, function and disability. Seven electronic databases were searched for TENS or IFC treatment in non-specific CLBP or CNP. Four reviewers independently selected randomized controlled trials (RCTs) of TENS or IFC intervention in adult individuals with non-specific CLBP or CNP. Primary outcomes were for self-reported pain intensity and back-specific disability. Two reviewers performed quality assessment, and two reviewers extracted data using a standardized form. Nine RCTs were selected (eight CLBP; one CNP), and seven studies with complete data sets were included for meta-analysis (655 participants). For CLBP, meta-analysis shows TENS/IFC intervention, independent of time of assessment, was significantly different from placebo/control (p TENS/IFC intervention was better than placebo/control, during therapy (p = 0.02), but not immediately after therapy (p = 0.08), or 1-3 months after therapy (p = 0.99). Analysis for adequate stimulation parameters was not significantly different, and there was no effect on disability. This systematic review provides inconclusive evidence of TENS benefits in low back pain patients because the quality of the studies was low, and adequate parameters and timing of assessment were not uniformly used or reported. Without additional high-quality clinical trials using sufficient sample sizes and adequate parameters and outcome assessments, the outcomes of this review are likely to remain unchanged. These data highlight the need for additional high-quality RCTs to examine the effects of TENS in CLBP. Trials should consider intensity of stimulation, timing of outcome assessment and assessment of pain, disability and function. © 2017 European Pain

  9. Investigation of the effect of traditional Chinese medicine on pain and inflammation in chronic nonbacterial prostatitis in rats. (United States)

    Liu, Y-J; Song, G-H; Liu, G T


    According to traditional Chinese medicine, the symptoms of chronic nonbacterial prostatitis/chronic pelvic pain syndrome (CNP/CPPS) may be treated using a cocktail of herbs that stimulate blood circulation ('activating blood circulation formula'). We investigated the effect of three doses of this formula on a rat model of CNP/CPPS. Male Wistar rats were injected with a saline extract of male sex accessory glands on days 0 and 30 to induce prostatitis and then treated daily by gavage between days 32 and 60. Treatment with low, medium and high doses of activating blood circulation formula resulted in an almost total rescue of paw withdrawal threshold at day 60, and treatment with the highest dose also significantly decreased prostate inflammation (assessed histopathologically). We further observed elevated serum prostaglandin E2 levels in the CNP/CPPS model which decreased upon high-dose treatment, and increased Cox-2 expression in the prostate and spinal cord dorsal horn which was rescued in both tissues in the high-dose group and in the prostate in the medium-dose group. These results shed light on a possible mechanism by which activating blood circulation therapy may alleviate pain in a rat model of CNP/CPPS by downregulating Cox-2 expression in the spinal cord, thereby raising the pain threshold. Further research will be needed to fully characterise the mechanism by which activating blood circulation therapy produces this therapeutic effect. © 2016 Blackwell Verlag GmbH.

  10. Effect of music on power, pain, depression and disability. (United States)

    Siedliecki, Sandra L; Good, Marion


    This paper reports a study testing the effect of music on power, pain, depression and disability, and comparing the effects of researcher-provided music (standard music) with subject-preferred music (patterning music). Chronic non-malignant pain is characterized by pain that persists in spite of traditional interventions. Previous studies have found music to be effective in decreasing pain and anxiety related to postoperative, procedural and cancer pain. However, the effect of music on power, pain, depression, and disability in working age adults with chronic non-malignant pain has not been investigated. A randomized controlled clinical trial was carried out with a convenience sample of 60 African American and Caucasian people aged 21-65 years with chronic non-malignant pain. They were randomly assigned to a standard music group (n = 22), patterning music group (n = 18) or control group (n = 20). Pain was measured with the McGill Pain Questionnaire short form; depression was measured with the Center for Epidemiology Studies Depression scale; disability was measured with the Pain Disability Index; and power was measured with the Power as Knowing Participation in Change Tool (version II). The music groups had more power and less pain, depression and disability than the control group, but there were no statistically significant differences between the two music interventions. The model predicting both a direct and indirect effect for music was supported. Nurses can teach patients how to use music to enhance the effects of analgesics, decrease pain, depression and disability, and promote feelings of power.

  11. Radiation therapy for nonmalignant diseases in Germany. Current concepts and future perspectives

    International Nuclear Information System (INIS)

    Heinrich Seegenschmiedt, M.; Micke, O.; Willich, N.


    Background: radiotherapy (RT) of nonmalignant diseases has a long-standing tradition in Germany. Over the past decade significant theoretical and clinical progress has been made in this field to be internationally recognized as an important segment of clinical RT. This development is reflected in a national patterns-of-care study (PCS) conducted during the years 2001-2002. Material and methods: in 2001 and 2002, a questionnaire was mailed to all RT facilities in Germany to assess equipment, patient accrual, RT indications, and treatment concepts. 146 of 180 institutions (81%) returned all requested data: 23 university hospitals (UNI), 95 community hospitals (COM), and 28 private institutions (PRIV). The specific diseases treated at each institution and the RT concepts were analyzed for frequencies and ratios between the different institution types. All data were compared to the first PCS in 1994-1996. Results: in 137 institutions (94%) 415 megavoltage units (mean 1.7; range 1-4), and in 78 institutions (53%) 112 orthovoltage units (mean 1.1; range 0-2) were available. A mean of 37,410 patients were treated per year in all institutions: 503 (1.3%) for inflammatory disorders, 23,752 (63.5%) for degenerative, 1,252 (3.3%) for hypertrophic, and 11,051 (29.5%) for functional, other and unspecified disorders. In comparison to the first PCS there was a significant increase of patients per year (from 20,082 to 37,410; +86.3%) in most nonmalignant diseases during the past 7-8 years. Most disorders were treated in accordance with the national consensus guidelines: the prescribed dose concepts (single and total doses) varied much less during the period 2001-2002 in comparison with the previous PCS in 1994-1996. Only five institutions (3.4%) received recommendations to change single or total doses and/or treatment delivery. Univariate analysis detected significant institutional differences in the use of RT for various disorders. Conclusion: RT is increasingly accepted in

  12. Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios?

    Directory of Open Access Journals (Sweden)

    H. Frigstad


    Full Text Available Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small deviations from the Redfield ratio (C:N:P = 106:16:1. Two time-series from the Norwegian shelf in Skagerrak are used to identify drivers of the seasonal variation in seston elemental ratios. An ordination identified water mass characteristics and bloom dynamics as the most important drivers for determining C:N, while changes in nutrient concentrations and biomass were most important for the C:P and N:P relationships. There is no standardized method for determining the functional composition of seston and the fractions of POC, PON and PP associated with phytoplankton, therefore any such information has to be obtained by indirect means. In this study, a generalized linear model was used to differentiate between the live autotrophic and non-autotrophic sestonic fractions, and for both stations the non-autotrophic fractions dominated with respective annual means of 76 and 55%. This regression model approach builds on assumptions (e.g. constant POC:Chl-a ratio and the robustness of the estimates were explored with a bootstrap analysis. In addition the autotrophic percentage calculated from the statistical model was compared with estimated phytoplankton carbon, and the two independent estimates of autotrophic percentage were comparable with similar seasonal cycles. The estimated C:nutrient ratios of live autotrophs were, in general, lower than Redfield, while the non-autotrophic C:nutrient ratios were higher than the live autotrophic ratios and above, or close to, the Redfield ratio. This is due to preferential remineralization of nutrients, and the P content mainly governed the difference between the sestonic fractions. Despite the seasonal variability in seston composition and the generally low contribution of autotrophic

  13. Effectiveness of traditional bone setting in chronic neck pain: randomized clinical trial. (United States)

    Zaproudina, Nina; Hänninen, Osmo O P; Airaksinen, Olavi


    This study evaluates the effectiveness of traditional bone setting (TBS) in chronic neck pain (cNP) compared with conventional physiotherapy (PT) and massage (M). This was a randomized clinical trial. Working-aged employed subjects with cNP (n = 105; 37 men and 68 women; mean age, 41.5 years) were randomized into TBS, PT, and M groups. Follow-up times were 1, 6, and 12 months after the treatments. Neck pain intensity (visual analog scale), perceived disability (Neck Disability Index [NDI]), and neck spine mobility measurements were used as outcomes. Global assessment was evaluated by the subjects (scale from -1 to +10). Data were analyzed using time (pre and post) by group (TBS, PT and M), 2- way analysis of variance for repeated measures. Neck pain decreased and NDI scores improved in all groups 1 month after the treatment (P better after TBS. Neck spine mobility in rotation movements tended to improve significantly better and the frons-knee distance improved more after TBS. One year later, both NDI and neck pain were significantly better after TBS than in reference groups. A significant improvement was reported by 40% to 45.5% of subjects in the PT and M groups and by 68.6% in the TBS group. Bone setters' ability to communicate and to interact with patients was evaluated significantly higher. In the TBS group, the number of sick days was minimal as was the use of painkillers during 1-year follow-up compared to that in the reference groups. Traditional bone setting, which is a soft manual mobilization technique focusing on the muscles, joints, and ligaments, appears to be effective in cNP. Two thirds of subjects experienced it as beneficial, and it seems to be able to improve disability and pain in patients with cNP. Subjective and partially objective benefits of TBS were found in those patients more than after other interventions, and the effects lasted at least for 1 year.

  14. The short-term effects of TENS plus therapeutic ultrasound combinations in chronic neck pain. (United States)

    Sayilir, Selcuk


    To investigate the effects of TENS plus therapeutic ultrasound combinations on symptom relief, physical functionality, perceived stress levels, daytime sleepiness and neck mobility in patients with chronic neck pain (CNP). A total of 64 patients were divided into two groups as the TENS plus ultrasound group (n = 39) and the control CNP group (n = 25). The therapy comprised TENS and therapeutic ultrasound applications for 10 sessions. The control subjects were discouraged from using analgesics but were allowed to use paracetamol daily, if necessary. The Neck Disability Index (NDI), Epworth Sleepiness Scale (ESS), Perceived Stress Scale (PSS), visual analog scale (VAS) and tragus-wall/chin-manubrium distances were recorded at the baseline and after therapy. Significant improvements were detected in the TENS plus ultrasound group compared to the control CNP subjects in respect of VAS, PSS and NDI scores after the TENS plus therapeutic ultrasound therapies (all p stress levels and improving functionality in the short-term of CNP.

    Chronic neuropathic pain (CNP) is one of the most significant unmet clinical needs in modern medicine. Alongside the lack of effective treatments, there is a great deficit in the availability of objective diagnostic methods to reliably facilitate an accurate diagnosis. We therefore aimed to determine the feasibility of a simple diagnostic test by analysing differentially expressed genes in the blood of patients diagnosed with CNP of the lower back and compared to healthy human controls. Refinement of microarray expression data was performed using correlation analysis with 3900 human 2-colour microarray experiments. Selected genes were analysed in the dorsal horn of Sprague-Dawley rats after L5 spinal nerve ligation (SNL), using qRT-PCR and ddPCR, to determine possible associations with pathophysiological mechanisms underpinning CNP and whether they represent translational biomarkers of CNP. We found that of the 15 potential biomarkers identified, tissue inhibitor of matrix metalloproteinase-1 (TIMP1) gene expression was upregulated in chronic neuropathic lower back pain (CNBP) (p = 0.0049) which positively correlated (R = 0.68, p = ≤0.05) with increased plasma TIMP1 levels in this group (p = 0.0433). Moreover, plasma TIMP1 was also significantly upregulated in CNBP than chronic inflammatory lower back pain (p = 0.0272). In the SNL model, upregulation of the Timp1 gene was also observed (p = 0.0058) alongside a strong trend for the upregulation of melanocortin 1 receptor (p = 0.0847). Our data therefore highlights several genes that warrant further investigation, and of these, TIMP1 shows the greatest potential as an accessible and translational CNP biomarker.

  16. In vivo toxicity of the culturable marine cyanobacterium Geitlerinema pseudacutissimum CNP 1019 extract on male Swiss albino mice (Mus musculus). (United States)

    Maruthanayagam, Veerabadhran; Nagarajan, Manivel; Sundararaman, Muthuraman


    In this study, we investigated the in vivo toxicity of Geitlerinema pseudacutissimum CNP 1019 organic extract in a murine host. A single intraperitoneal injection of 1 g extract kg⁻¹ body weight (BW) did not exhibit mortality, whereas 3 g extract kg⁻¹ BW (approximate lethal dose) resulted in mortality within 5 days. To perform subchronic exposure toxicity analyses (i.e., daily exposure for a total of 14 days), a maximum concentration of ≤1 g extract kg⁻¹ BW was used. Subchronic toxicity studies in the treated mice, showed fluctuations of feed intake, loss of body weight, increase in specific activity of serum lactate dehydrogenase, alanine aminotransferase and decrease in whole serum protein concentration. LDH isoenzyme expression was found, and levels of the various isoforms were decreased as a result of the treatment. Histopathology studies in liver, kidney, and spleen isolated from the treated mice showed the presence of necrotic debris, hemorrhage, and micronuclei revealing the toxicity of the extract. The dose-dependent alterations in biochemical parameters in conjunction with the histological lesions noted in the animals treated with the prepared extract illustrate the likely potential toxicity to mammals from any encounters with the studied cyanobacterium.

  17. Aberrant immunoglobulin and c-myc gene rearrangements in patients with nonmalignant monoclonal cryoglobulinemia

    The status of the immunoglobulin (Ig) genes was investigated in patients with idiopathic nonmalignant monoclonal IgG cryoglobulinemia (NCG). In NCG, monoclonal antibodies are synthesized at an accelerated rate by nonmalignant B lymphocytes. In order to determine whether this high production rate is related to a clonal B cell expansion, the rearrangement of the Ig genes was investigated by Southern blot analysis of genomic, 32 P-labelled, DNA extracted from the peripheral blood lymphocytes of four NCG patients. In three of four (VI, BR, and CH) clonal expansion of B cells was detected using probes specific for the genes. BamHI digestion of DNA from VI and BR produced three rearranged fragments which cohybridized with two of the probes. This finding suggested the presence of additional nonsecretory B cell clones and/or disruption of the gene segments spanned by and detected with the probes. In addition, the possibility of aberrant gene rearrangements was supported by noting the alteration of the c-myc gene locus in genomic DNA from peripheral blood leukocytes of VI and CH. Northern blot analysis of RNA isolated from peripheral blood B cells of VI and CH demonstrated aberrant transcripts of the c-myc gene, showing an active role of the altered c-myc locus. Detection of c-myc rearrangement in NCG patients clearly shows that this event may not be a final step in malignant B cell transformation

  18. Effects of taxonomy, sediment, and water column on C:N:P stoichiometry of submerged macrophytes in Yangtze floodplain shallow lakes, China. (United States)

    Su, Haojie; Wu, Yao; Xie, Ping; Chen, Jun; Cao, Te; Xia, Wulai


    Carbon (C), nitrogen (N) and phosphorus (P) are the three most important essential elements limiting growth of primary producers. Submerged macrophytes generally absorb nutrients from sediments by root uptake. However, the C:N:P stoichiometric signatures of plant tissue are affected by many additional factors such as taxonomy, nutrient availability, and light availability. We first revealed the relative importance of taxonomy, sediment, and water column on plant C:N:P stoichiometry using variance partitioning based on partial redundancy analyses. Results showed that taxonomy was the most important factor in determining C:N:P stoichiometry, then the water column and finally the sediment. In this study, a significant positive relationship was found between community C concentration and macrophyte community biomass, indicating that the local low C availability in macrophytes probably was the main reason why submerged macrophytes declined in Yangtze floodplain shallow lakes. Based on our study, it is suggested that submerged macrophytes in Yangtze floodplain shallow lakes are primarily limited by low light levels rather than nutrient availability.

  19. Bone marrow-derived CD13+ cells sustain tumor progression: A potential non-malignant target for anticancer therapy. (United States)

    Dondossola, Eleonora; Corti, Angelo; Sidman, Richard L; Arap, Wadih; Pasqualini, Renata


    Non-malignant cells found within neoplastic lesions express alanyl (membrane) aminopeptidase (ANPEP, best known as CD13), and CD13-null mice exhibit limited tumor growth and angiogenesis. We have recently demonstrated that a subset of bone marrow-derived CD11b + CD13 + myeloid cells accumulate within neoplastic lesions in several murine models of transplantable cancer to promote angiogenesis. If these findings were confirmed in clinical settings, CD11b + CD13 + myeloid cells could become a non-malignant target for the development of novel anticancer regimens.

  20. Non-malignant disease mortality in meat workers: a model for studying the role of zoonotic transmissible agents in non-malignant chronic diseases in humans. (United States)

    Johnson, E S; Zhou, Y; Sall, M; Faramawi, M El; Shah, N; Christopher, A; Lewis, N


    Current research efforts have mainly concentrated on evaluating the role of substances present in animal food in the aetiology of chronic diseases in humans, with relatively little attention given to evaluating the role of transmissible agents that are also present. Meat workers are exposed to a variety of transmissible agents present in food animals and their products. This study investigates mortality from non-malignant diseases in workers with these exposures. A cohort mortality study was conducted between 1949 and 1989, of 8520 meat workers in a union in Baltimore, Maryland, who worked in manufacturing plants where animals were killed or processed, and who had high exposures to transmissible agents. Mortality in meat workers was compared with that in a control group of 6081 workers in the same union, and also with the US general population. Risk was estimated by proportional mortality and standardised mortality ratios (SMRs) and relative SMR. A clear excess of mortality from septicaemia, subarachnoid haemorrhage, chronic nephritis, acute and subacute endocarditis, functional diseases of the heart, and decreased risk of mortality from pre-cerebral, cerebral artery stenosis were observed in meat workers when compared to the control group or to the US general population. The authors hypothesise that zoonotic transmissible agents present in food animals and their products may be responsible for the occurrence of some cases of circulatory, neurological and other diseases in meat workers, and possibly in the general population exposed to these agents.

The isolats were used are Acinetobacter baumanni, Alcaligenes eutrophus, Bacillus sp1., Methylococcus capsulatus, Bacillus sp2., Morococcus sp., Pseudomonas diminuta, Xanthomonas albilineans, Bacillus cereus and Flavobacterium branchiophiia. Variation of inoculum concentrations were 10%, 15%, and 20% (v/v, C:N:P ratios were 100:10:1, 100:10:0,5, 100:5:1, and 100:5:0,5, and pH were 6,5, 7,0, 7,5. Observed parameters in optimization were Total Plate Count (TPC the culture every 24 hours, Total Petroleum Hydrocarbon (TPH and Chemical Oxygen Demand (COD examined at the end of the bioremediation period. Best optimization result then analyzed with GC/MS. Optimization result indicated the best inoculum concentration was 10% with TPH degradation 61,79% and COD slope 61,75%. It is assumed that the low value of TPH degradation and COD slope at 15% and 20% inoculum concentration were caused by competition inside the bacterial population at that high inoculum concentration. The competition result in low growth and degradation. C:N:P ratio was 100:5:1 with TPH degradation 66,55% and COD slope 85,18%. It is assumed that the C:N:P ratio is equal, so it can enhance the bioremediation procces. The best pH was 7,5 with TPH degradation 73,24% and COD slope 86,28%. The process at the optimum conditions using inoculum as a mixed culture enhanced the bioremediation process with the result as follows, TPH degradation 93,06%, COD 90,73% for treatment. The chromatogram indicated that total hydrocarbon compound from nC9 – nC32 have been degraded by 43,413% – 63,117%. A good result of bioremediation was obtained from mixed culture inoculum at 10% concentration, C:N:P ratio of 100:5:1, and pH 7,5.

    Full Text Available The surficial sediments recovered from 12 sites located near the channel axis of the Florida Straits and the lower slope off NW Cuba were analyzed for total organic carbon (TOC, nitrogen (TN, phosphorus (TP, elemental C:N:P ratios, C and N isotopic values, and 14C dating. The depth profiles of TOC, TN, and TP (0-18 cm displayed a downcore trend and a significant variation. The TOC values were low (0.15 to 0.62%; 66 to 516 µmol g(-1. Sites near the island's lower slope had lower TOC average concentrations (158-333 µmol g(-1 than those closer to the channel axis (averaging 341-516 µmol g(-1; p <0.05. The TN concentrations near the lower slope attained 0.11% (80 µmol g(-1, whereas, towards the channel axis, they decreased to 0.07% (55 µmol g(-1; p<0.05. The C:N ratios ranged from 1.9 to 10.2. The mean molar C:N ratio (5.4 indicated a marine hemipelagic deposition. The TP was lower at sites near the lower slope (38.4 to 50.0 µmol gv; 0.12% to 0.16% than those near the channel axis (50.0 to 66 µmol g(-1; 0.15 to 0.21%. C:P fluctuated from 7.7 to 14.1 in the surficial sediment layer. The bulk organic δ13Corg and δ15N values confirmed pelagic organic sources, and the 14C dating revealed that the sediments were deposited during the Holocene (1000-5000 yr BP. We suggest that the hydrodynamic conditions in the Straits influence vertical and advective fluxes of particulate organic material trapped in the mixed-layer, which reduces the particulate matter flux to the seabed.

  4. Cooperative effects of aminopeptidase N (CD13) expressed by nonmalignant and cancer cells within the tumor microenvironment. (United States)

    Processes that promote cancer progression such as angiogenesis require a functional interplay between malignant and nonmalignant cells in the tumor microenvironment. The metalloprotease aminopeptidase N (APN; CD13) is often overexpressed in tumor cells and has been implicated in angiogenesis and cancer progression. Our previous studies of APN-null mice revealed impaired neoangiogenesis in model systems without cancer cells and suggested the hypothesis that APN expressed by nonmalignant cells might promote tumor growth. We tested this hypothesis by comparing the effects of APN deficiency in allografted malignant (tumor) and nonmalignant (host) cells on tumor growth and metastasis in APN-null mice. In two independent tumor graft models, APN activity in both the tumors and the host cells cooperate to promote tumor vascularization and growth. Loss of APN expression by the host and/or the malignant cells also impaired lung metastasis in experimental mouse models. Thus, cooperation in APN expression by both cancer cells and nonmalignant stromal cells within the tumor microenvironment promotes angiogenesis, tumor growth, and metastasis.

  5. Immunohistochemical and radioimmunological demonstration of alpha1-fetoprotein in nonmalignant changes of human gastric mucosa

    International Nuclear Information System (INIS)

    Falser, N.; Lederer, B.; Reissigl, H.; Innsbruck Univ.


    The occurence of α 1 fetoprotein in nonmalignant changes of the gastric mucosa was investigated by means of immunohistochemistry and radioimmunonoassay. The investigations were performed in tissue sections, cytological imprint preparations as well as in homogenized tissue samples (obtained by gastroscopy). α 1 fetoprotein could be demonstrated by immuno-histochemistry in about 90% of the samples originating from the surroundings of gastric ulcer and the region of gastrojejunostomy after B II-resection. The RIA was positive in about 75% of the tissue samples, whereas from gastric juice only 40% of positive results could be obtained. No α 1 fetoprotein-activity could be demonstrated in serum samples. These investigations indicate that α 1 fetoprotein is not exclusively synthesized by embryonic or neoplastic tissues and also can be synthesized also by regenerating cell-systems. It may be supposed that this synthesis represents an unspecific answer to growth-stimulation. (orig.) [de

  6. Colorectal cancer and non-malignant respiratory disease in asbestos cement and cement workers

    International Nuclear Information System (INIS)

    Jacobsson, K.


    Radiologically visible parenchymal changes (small opacities >= 1/0;ILO 1980 classification) were present in 20% of a sample of workers (N=174), employed for 20 years (median) in an asbestos cement plant. Exposure-response relationships were found, after controlling for age and smoking habits. In a sample of asbestos cement workers with symptoms and signs suggestive of pulmonary disease (N=33), increased lung density measured by x-ray computed tomography, and reduced static lung volumes and lung compliance was found. In a cohort of asbestos cement workers (N=1.929) with an estimated median exposure of 1.2 fibres/ml, the mortality from non-malignant respiratory disease was increased in comparison to a regional reference cohort (N=1.233). A two-to three-fold increase of non-malignant respiratory mortality was noted among workers employed for more than a decade in the asbestos cement plant, compared to cement workers (N=1.526), who in their turn did not experience and increased risk compared to the general population. In the cohorts of asbestos cement and cement workers, there was a tow-to three-fold increased incidence of cancer in the right part of the colon, compared to the general population as well as to external reference cohorts of other industrial workers (N=3.965) and fishermen (N=8.092). A causal relation with the exposure to mineral dust and fibres was supported by the findings of higher risk estimated in subgroups with high cumulated asbestos doses or longer duration of cement work. The incidence of cancer in the left part of the colon was not increased. Morbidity data, but not mortality data, disclosed the subsite-specific risk pattern. Both asbestos cement workers and cement workers has an increased incidence of rectal cancer, compared with the general population, and with the fishermen. The risk was, however, of the same magnitude among the other industrial workers. 181 refs

    To investigate the consequences of improvement in the workplace environment over six decades (1940-96) in asbestos miners and millers from a developing country (Brazil). A total of 3634 Brazilian workers with at least one year of exposure completed a respiratory symptoms questionnaire, chest radiography, and a spirometric evaluation. The study population was separated into three groups whose working conditions improved over time: group I (1940-66, n = 180), group II (1967-76, n = 1317), and group III (1977-96, n = 2137). Respiratory symptoms were significantly related to spirometric abnormalities, smoking, and latency time. Breathlessness, in particular, was also associated with age, pleural abnormality and increased cumulative exposure to asbestos fibres. The odds ratios (OR) for parenchymal and/or non-malignant pleural disease were significantly lower in groups II and III compared to group I subjects (0.29 (0.12-0.69) and 0.19 (0.08-0.45), respectively), independent of age and smoking status. Similar results were found when groups were compared at equivalent latency times (groups I v II: 30-45 years; groups II v III: 20-25 years). Ageing, dyspnoea, past and current smoking, and radiographic abnormalities were associated with ventilatory impairment. Lower spirometric values were found in groups I and II compared to group III: lung function values were also lower in higher quartiles of latency and of cumulative exposure in these subjects. Progressive improvement in occupational hygiene in a developing country is likely to reduce the risk of non-malignant consequences of dust inhalation in asbestos miners and millers.

    To determine the effectiveness of Pilates and yoga group exercise interventions for individuals with chronic neck pain (CNP). Quasi-randomised parallel controlled study. Community, university and private practice settings in four locations. Fifty-six individuals with CNP scoring ≥3/10 on the numeric pain rating scale for >3 months (controls n=17, Pilates n=20, yoga n=19). Exercise participants completed 12 small-group sessions with modifications and progressions supervised by a physiotherapist. The primary outcome measure was the Neck Disability Index (NDI). Secondary outcomes were pain ratings, range of movement and postural measurements collected at baseline, 6 weeks and 12 weeks. Follow-up was performed 6 weeks after completion of the exercise classes (Week 18). NDI decreased significantly in the Pilates {baseline: 11.1 [standard deviation (SD) 4.3] vs Week 12: 6.8 (SD 4.3); mean difference -4.3 (95% confidence interval -1.64 to -6.7); PPilates and yoga group exercise interventions with appropriate modifications and supervision were safe and equally effective for decreasing disability and pain compared with the control group for individuals with mild-to-moderate CNP. Physiotherapists may consider including these approaches in a plan of care. NCT01999283. Copyright © 2015 Chartered Society of Physiotherapy. Published by Elsevier Ltd. All rights reserved.

  9. Sense of social support in chonic pain patients

    Full Text Available Statistical data show that one in five adults of the European citizen suffer from some type of chronic pain. One of the most common types of chronic pain is chronic low back and neck pain. Emotional factors are currently viewed as important determinants in pain perception and behaviour. The perceived social and emotional support have impact to the individual’s adaptation to chronic disease (Cohen, Wills, 1985. The material: 110 chronic low back pain (CLBP patients (48 male and 62 female; in age from 24 to 60 years, mean: 44.2±8, 0 and pilot study of 23 chronic neck pain (CNP patients (19 female and 4 male; in age from 35 to 60 years, mean: 48, 1 ±6. The assessment methods: structured interview; Hospital Anxiety and Depression Scale (HADS. SF-36 ® Health Survey: assessment of emotional and social support. Results and conclusions: CLBP patients in presence of symptoms of depression and elevated level of anxiety matched for socio-demographic features had less sense of social support and marked pain impact to daily activities, lower self rating health relating quality of life. In CLBP patients the sense of social and emotional support had relevant interaction with level of participation in daily activities both in patients with and without mental health problems. This fact has to be considered in process of rehabilitation and in managing of health care of CLBP patients. The results of CNP patients pilot study revealed interesting trend that chronic back and neck pain patients seems to be quite different according to sense of social and emotional support, therefore sense of social and emotional support in different chronic pain patients need further research to improve the process and results of rehabilitation in these patients.

  10. Transjugular portal vein recanalization with creation of intrahepatic portosystemic shunt (PVR-TIPS) in patients with chronic non-cirrhotic, non-malignant portal vein thrombosis. (United States)

    Klinger, Christoph; Riecken, Bettina; Schmidt, Arthur; De Gottardi, Andrea; Meier, Benjamin; Bosch, Jaime; Caca, Karel


    To determine safety and efficacy of transjugular portal vein recanalization with creation of intrahepatic portosystemic shunt (PVR-TIPS) in patients with chronic non-cirrhotic, non-malignant portal vein thrombosis (PVT). This retrospective study includes 17 consecutive patients with chronic non-cirrhotic PVT (cavernous transformation n = 15). PVR-TIPS was indicated because of variceal bleeding (n = 13), refractory ascites (n = 2), portal biliopathy with recurrent cholangitis (n = 1), or abdominal pain (n = 1). Treatment consisted of a combination of transjugular balloon angioplasty, mechanical thrombectomy, and-depending on extent of residual thrombosis-transjugular intrahepatic portosystemic shunt and additional stenting of the portal venous system. Recanalization was successful in 76.5 % of patients despite cavernous transformation in 88.2 %. Both 1- and 2-year secondary PV and TIPS patency rates were 69.5 %. Procedure-related bleeding complications occurred in 2 patients (intraperitoneal bleeding due to capsule perforation, n = 1; liver hematoma, n = 1) and resolved spontaneously. However, 1 patient died due to subsequent nosocomial pneumonia. During follow-up, 3 patients with TIPS occlusion and PVT recurrence experienced portal hypertensive complications. PVR-TIPS is safe and effective in selected patients with chronic non-cirrhotic PVT. Due to technical complexity and possible complications, it should be performed only in specialized centers with high experience in TIPS procedures. © Georg Thieme Verlag KG Stuttgart · New York.

    The integral cross section of the $^{12}$C($n,p$)$^{12}$B reaction has been determined for the first time in the neutron energy range from threshold to several GeV at the n_TOF facility at CERN. The measurement relies on the activation technique, with the $\\beta$-decay of $^{12}$B measured over a period of four half-lives within the same neutron bunch in which the reaction occurs. The results indicate that model predictions, used in a variety of applications, are mostly inadequate. The value of the integral cross section reported here can be used as a benchmark for verifying or tuning model calculations.

  13. CNP-1 (ARRD-17), a novel substrate of calcineurin, is critical for modulation of egg-laying and locomotion in response to food and lysine sensation in Caenorhabditis elegans. (United States)

    Jee, Changhoon; Choi, Tae-Woo; Kalichamy, Karunambigai; Yee, Jong Zin; Song, Hyun-Ok; Ji, Yon Ju; Lee, Jungsoo; Lee, Jin Il; L'Etoile, Noelle D; Ahnn, Joohong; Lee, Sun-Kyung


    Calcineurin is a Ca(2+)/calmodulin-dependent protein phosphatase involved in calcium signaling pathways. In Caenorhabditis elegans, the loss of calcineurin activity causes pleiotropic defects including hyperadaptation of sensory neurons, hypersensation to thermal difference and hyper-egg-laying when worms are refed after starvation. In this study, we report on arrd-17 as calcineurin-interacting protein-1 (cnp-1), which is a novel molecular target of calcineurin. CNP-1 interacts with the catalytic domain of the C. elegans calcineurin A subunit, TAX-6, in a yeast two-hybrid assay and is dephosphorylated by TAX-6 in vitro. cnp-1 is expressed in ASK, ADL, ASH and ASJ sensory neurons as TAX-6. It acts downstream of tax-6 in regulation of locomotion and egg-laying after starvation, ASH sensory neuron adaptation and lysine chemotaxis, that is known to be mediated by ASK neurons. Altogether, our biochemical and genetic evidence indicates that CNP-1 is a direct target of calcineurin and required in stimulated egg-laying and locomotion after starvation, adaptation to hyperosmolarity and attraction to lysine, which is modulated by calcineurin. We suggest that the phosphorylation status of CNP-1 plays an important role in regulation of refed stimulating behaviors after starvation and attraction to amino acid, which provides valuable nutritious information.

We aimed to devise and validate a stimulator with a novel design entailing a multitude of small coils at known anatomical positions on a head cap, to improve applicability. The main hypothesis was that CNP delivery with this novel device would also increase heat pain thresholds. Twenty healthy volunteers were enrolled in this double-blind, sham-controlled, crossover study. Thirty minutes of PEMF (CNP or sham was applied to the head. After one week the other treatment was given. Before and after each treatment, primary and secondary outcomes were measured. Primary outcome was heat pain threshold (HPT measured with thermal quantitative sensory testing. Other outcomes were warmth detection threshold, and aspects of cognition, emotion and motor performance. As hypothesized heat pain threshold was significantly increased after the PEMF stimulation. All other outcomes were unaltered by the PEMF but there was a trend level reduction of cognitive performance after PEMF stimulation as measured by the digit-symbol substitution task. Results from this pilot study suggest that our device is able to stimulate the brain and to modulate its function. This is in agreement with previous studies that used similar magnetic field strengths to stimulate the brain. Specifically, pain control may be achieved with PEMF and for this analgesic effect, coil design does not appear to play a dominant role. In addition, the flexible configuration with small coils on a head cap improves clinical applicability. TRIAL REGISTRATION: Dutch Cochrane Centre NTR1093.

  15. Non-malignant causes of hypercalcemia in cancer patients: a frequent and neglected occurrence. (United States)

    Soyfoo, M S; Brenner, K; Paesmans, M; Body, J J


    Hypercalcemia is a frequent finding in cancer patients and can be observed in any type of cancer. The physician in charge of cancer patients often ignores non-malignant causes of hypercalcemia. Our objective was to review the causes of hypercalcemia in a large series of cancer patients. We have retrospectively studied in a Cancer Centre all consecutive hypercalcemic (Ca> 10.5 mg/dl) patients over an 8-year period. Of 699 evaluated patients, 642 were analyzed after exclusion of patients whose hypercalcemia resolved after rehydration or who had a normal Ca level after correction for protein concentrations. Clinical information was gathered on the type of cancer, its histology, whether the disease was active or in complete remission, and on the presence of bone metastases. Biochemical data included serum Ca, P(i), proteins in all patients, PTH in most patients, and PTHrP, 25OH-Vitamin D, 1,25(OH)(2)-Vitamin D, TSH, and T4 in selected cases. By order of decreasing frequency, the main causes of hypercalcemia were cancer (69.0 %), primary hyperparathyroidism (24.6 %), hyperthyroidism (2.2 %), milk alkali syndrome (0.9 %), and sarcoidosis (0.45 %). In cancer-related causes, bone metastases accounted for 53.0 % of the cases, humoral hypercalcemia of malignancy (HHM) for 35.3 % while there were 11.7 % of cases apparently due to both HHM and bone metastases. Hypercalcemia was not due to cancer in 97 % (84/87) of the patients who were in complete remission. Even in patients with active neoplastic disease, the number of patients whose hypercalcemia was not due to cancer remained clinically relevant (115/555 = 20.5 %). In the 158 patients with primary hyperparathyroidism, 92 patients were in complete remission and 66 patients had active neoplastic disease. In this large series of hypercalcemia in cancer patients, the cause was not due to cancer in almost one third of the cases. Most patients considered to be in complete remission had hypercalcemia due to a benign

    Full Text Available Background: Acquired paralysis of the diaphragm is a condition caused by trauma, surgical injuries, (lung cancer surgery, esophageal surgery, cardiac surgery, thoracic surgery, and is sometimes of an unknown etiology. It can lead to dyspnea and can affect ventilatory function and patients activity. Diaphragmatic plication is a treatment method which decreases inconsistent function of diaphragm. The aim of this study is to evaluate the outcome of diaphragmatic plication in patients with acquired unilateral non-malignant diaphragmatic paralysis. Methods: From 1991 to 2011, 20 patients with acquired unilateral diaphragmatic paralysis who underwent surgery enrolled in our study in Ghaem Hospital Mashhad University of Medical Science. Patients were evaluated in terms of age, sex, BMI, clinical symptoms, dyspnea score (DS, etiology of paralysis, diagnostic methods, respiratory function tests and complication of surgery. Some tests including dyspnea score were carried out again six months after surgery. We evaluated patients with SPSS version 11.5 and Paired t-test or nonparametric equivalent. Results: Twenty patients enrolled in our study. 14 were male and 6 were female. The mean age was 58 years and the average time interval between diagnosis to surgical treatment was 38.3 months. Acquired diaphragmatic paralysis was mostly caused by trauma (in 11 patients and almost occurred on the left side (in 15 patients. Diagnostic methods included chest x-ray, CT scan, ultrasonography and sniff. Test prior to surgery the average FVC was 41.4±7 percent and the average FEV1 was 52.4±6 percent and after surgery they were 80.1±8.6 percent and 74.4±1 percent respectively. The average increase in FEV1 and FVC 63.4±4, 61.1±7.8. Performing surgery also leads to a noticeable improvement in dyspnea score in our study. Conclusion: In patients with acquired unilateral non-malignant diaphragm paralysis diaphragmatic plication is highly recommended due to the

  19. CD47 limits antibody dependent phagocytosis against non-malignant B cells. (United States)

    Gallagher, Sandra; Turman, Sean; Lekstrom, Kristen; Wilson, Susan; Herbst, Ronald; Wang, Yue


    Recent studies have demonstrated the importance of CD47 in protecting malignant B cells from antibody dependent cellular phagocytosis (ADCP). Combined treatment of anti-CD47 and -CD20 antibodies synergistically augment elimination of tumor B cells in xenograft mouse models. This has led to the development of novel reagents that can potentially enhance killing of malignant B cells in patients. B cell depleting therapy is also a promising treatment for autoimmune patients. In the current study, we aimed to investigate whether or not CD47 protects non-malignant B cells from ADCP. We show that CD47 is expressed on all B cells in mice, with the highest level on plasma cells in bone marrow and spleen. Although its expression is dispensable for B cell development in mice, CD47 on B cells limits antibody mediated phagocytosis. B cell depletion following in vivo anti-CD19 treatment is more efficient in CD47-/- mice than in wild type mice. In vitro, both naïve and activated B cells from CD47-/- mice are more sensitive to ADCP than wild type B cells. Lastly, we show in an ADCP assay that blocking CD47 can enhance anti-CD19 antibody mediated phagocytosis of wild type B cells. These results suggest that in addition to its already demonstrated benefit in cancer, targeting CD47 may be used as an adjunct in combination with B cell depletion antibodies for treatment of autoimmune diseases.

  20. Changes of postural control and muscle activation pattern in response to external perturbations after neck flexor fatigue in young subjects with and without chronic neck pain. (United States)

    Previous studies have identified sensorimotor disturbances and greater fatigability of neck muscles in patients with neck pain. The purpose of this study was to investigate the effect of neck pain and neck flexor fatigue on standing balance following postural perturbations. Twenty patients with chronic neck pain (CNP) (24.7±3.6 year-old) and 20 age-matched asymptomatic subjects (22.1±2.2 year-old) were recruited. Subjects stood barefoot on a force plate and experienced backward perturbations before and after neck flexor fatigue. Center of pressure, electromyography of cervical and lumbar muscles, and head/trunk accelerations were recorded. Two-way ANOVA (pain×fatigue) was used for statistical analysis. CNP group showed larger body sway during quiet standing but not during perturbed standing compared with asymptomatic adults. In both groups, neck flexor fatigue resulted in greater body sway during the quiet standing but smaller body sway during perturbed standing, increased neck muscle activations and decreased lumbar muscle activations, as well as increased time to maximal head acceleration. Disturbed balance control was observed in CNP patients during the quiet standing. However, a rigid strategy was used to minimize the postural sway and to protect the head against backward perturbations in both CNP and asymptomatic young adults after neck flexor fatigue. The results facilitate the understanding of how the subjects with chronic neck pain and with neck muscle fatigue deal with the challenging condition. Further studies are needed to verify if such phenomenon could be changed after the intervention of specific flexor muscle retraining and balance control exercises. Copyright © 2015 Elsevier B.V.

    Full Text Available Introduction. Cupping has been used since antiquity in the treatment of pain conditions. In this pilot study, we investigated the effect of traditional cupping therapy on chronic nonspecific neck pain (CNP and mechanical sensory thresholds. Methods. Fifty CNP patients were randomly assigned to treatment (TG, n=25 or waiting list control group (WL, n=25. TG received a single cupping treatment. Pain at rest (PR, pain related to movement (PM, quality of life (SF-36, Neck Disability Index (NDI, mechanical detection (MDT, vibration detection (MDT, and pressure pain thresholds (PPT were measured before and three days after a single cupping treatment. Patients also kept a pain and medication diary (PaDi, MeDi during the study. Results. Baseline characteristics were similar in the two groups. After cupping TG reported significantly less pain (PR: −17.9 mm VAS, 95%CI −29.2 to −6.6; PM: −19.7, 95%CI −32.2 to −7.2; PaDi: −1.5 points on NRS, 95%CI −2.5 to −0.4; all P<0.05 and higher quality of life than WL (SF-36, Physical Functioning: 7.5, 95%CI 1.4 to 13.5; Bodily Pain: 14.9, 95%CI 4.4 to 25.4; Physical Component Score: 5.0, 95%CI 1.4 to 8.5; all P<0.05. No significant effect was found for NDI, MDT, or VDT, but TG showed significantly higher PPT at pain-areas than WL (in lg(kPa; pain-maximum: 0.088, 95%CI 0.029 to 0.148, pain-adjacent: 0.118, 95%CI 0.038 to 0.199; both P<0.01. Conclusion. A single application of traditional cupping might be an effective treatment for improving pain, quality of life, and hyperalgesia in CNP.

    Full Text Available Water and nitrogen availability plays an important role in the biogeochemical cycles of essential elements, such as carbon (C, nitrogen (N and phosphorus (P, in agricultural ecosystems. In this study, we investigated the seasonal changes of C, N and P concentrations, accumulation, partitioning, and C:N:P stoichiometric ratios in different plant tissues (root, stem-leaf, and panicle of late-season rice under two irrigation regimes (continuous flooding, CF; alternate wetting and drying, AWD and four N managements (control, N0; conventional urea at 240 kg N ha(-1, UREA; controlled-release bulk blending fertilizer at 240 kg N ha(-1, BBF; polymer-coated urea at 240 kg N ha(-1, PCU. We found that water and N treatments had remarkable effects on the measured parameters in different plant tissues after transplanting, but the water and N interactions had insignificant effects. Tissue C:N, N:P and C:P ratios ranged from 14.6 to 52.1, 3.1 to 7.8, and 76.9 to 254.3 over the rice growing seasons, respectively. The root and stem-leaf C:N:P and panicle C:N ratios showed overall uptrends with a peak at harvest whereas the panicle N:P and C:P ratios decreased from filling to harvest. The AWD treatment did not affect the concentrations and accumulation of tissue C and N, but greatly decreased those of P, resulting in enhanced N:P and C:P ratios. N fertilization significantly increased tissue N concentration, slightly enhanced tissue P concentration, but did not affect tissue C concentration, leading to a significant increase in tissue N:P ratio but a decrease in C:N and C:P ratios. Our results suggested that the growth of rice in the Taihu Lake region was co-limited by N and P. These findings broadened our understanding of the responses of plant C:N:P stoichiometry to simultaneous water and N managements in subtropical high-yielding rice systems.

  5. The role of C:N:P stoichiometry in affecting denitrification in sediments from agricultural surface and tile-water wetlands. (United States)

    Grebliunas, Brian D; Perry, William L


    Nutrient stoichiometry within a wetland is affected by the surrounding land use, and may play a significant role in the removal of nitrate (NO3-N). Tile-drained, agricultural watersheds experience high seasonal inputs of NO3-N, but low phosphorus (PO4-P) and dissolved organic carbon (DOC) loads relative to surface water dominated systems. This difference may present stoichiometric conditions that limit denitrification within receiving waterways. We investigated how C:N:P ratios affected denitrification rates of sediments from tile-drained mitigation wetlands incubated for: 0, 5, 10, and 20 days. We then tested whether denitrification rates of sediments from surface-water and tile-drained wetlands responded differently to C:N ratios of 2:1 versus 4:1. Ratios of C:N:P (P tile-drained wetland sediments. Carbon limitation of denitrification became evident at elevated NO3-N concentrations (20 mg L(-1)). Denitrification measured from tile water and surface water wetland sediments increased significantly (P < 0.05) at the 2:1 and 4:1 C:N treatments. The results from both experiments suggest wetland sediments provide a limiting pool of labile DOC to maintain prolonged NO3-N removal. Also, DOC limitation became more evident at elevated NO3-N concentrations (20 mg L(-1)). Irrespective of NO3-N concentrations, P did not limit denitrification rates. In addition to wetting period, residence time, and maintenance of anaerobic conditions, the availability of labile DOC is playing an important limiting role in sediment denitrification within mitigation wetlands.

  6. Impact of locomotion training with a neurologic controlled hybrid assistive limb (HAL) exoskeleton on neuropathic pain and health related quality of life (HRQoL) in chronic SCI: a case study (.). (United States)

    Cruciger, Oliver; Schildhauer, Thomas A; Meindl, Renate C; Tegenthoff, Martin; Schwenkreis, Peter; Citak, Mustafa; Aach, Mirko


    Chronic neuropathic pain (CNP) is a common condition associated with spinal cord injury (SCI) and has been reported to be severe, disabling and often treatment-resistant and therefore remains a clinical challenge for the attending physicians. The treatment usually includes pharmacological and/or nonpharmacological approaches. Body weight supported treadmill training (BWSTT) and locomotion training with driven gait orthosis (DGO) have evolved over the last decades and are now considered to be an established part in the rehabilitation of SCI patients. Conventional locomotion training goes along with improvements of the patients' walking abilities in particular speed and gait pattern. The neurologic controlled hybrid assistive limb (HAL®, Cyberdyne Inc., Ibraki, Japan) exoskeleton, however, is a new tailored approach to support motor functions synchronously to the patient's voluntary drive. This report presents two cases of severe chronic and therapy resistant neuropathic pain due to chronic SCI and demonstrates the beneficial effects of neurologic controlled exoskeletal intervention on pain severity and health-related quality of life (HRQoL). Both of these patients were engaged in a 12 weeks period of daily HAL®-supported locomotion training. In addition to improvements in motor functions and walking abilities, both show significant reduction in pain severity and improvements in all HRQoL domains. Although various causal factors likely contribute to abatement of CNP, the reported results occurred due to a new approach in the rehabilitation of chronic spinal cord injury patients. These findings suggest not only the feasibility of this new approach but in conclusion, demonstrate the effectiveness of neurologic controlled locomotion training in the long-term management of refractory neuropathic pain. Implications for Rehabilitation CNP remains a challenge in the rehabilitation of chronic SCI patients. Locomotion training with the HAL exoskeleton seems to improve CNP

    Ajo, Raquel; Segura, Ana; Inda, María M; Planelles, Beatriz; Martínez, Luz; Ferrández, Guillermina; Sánchez, Angel; César Margarit; Peiró, Ana-María


    Long-term opioid therapy has been found to have a strong impact on the hypothalamic-pituitary-gonadal axis that can be manifested clinically by sexual dysfunction (SD). This event is rarely reported and thus unnoticed and undertreated. To analyze the presence of SD in a large group of patients receiving long-term opioids. A descriptive, cross-sectional pilot study of sexual health was conducted for 2 years in 750 consecutive ambulatory patients with chronic non-cancer pain (CNP) receiving opioids for at least 12 months. Cases that reported SD and matched controls were included. Standardized questionnaires and medical record reviews were used to assess rates of pain at diagnosis, daily morphine equivalent doses, and opioid adverse effects. Sexual function was determined by the Female Sexual Function Index (FSFI; scores = 2-36) and the International Index of Erectile Function erectile function domain (IIEF-EF; scores = 1-30). Thirty-three percent of 33% of 750 patients with CNP recorded SD based on their spontaneous notification at the pain unit. Men reported SD significantly more frequently than women (33% vs 25%, respectively, P sexually active life (69% vs 34%, respectively, P = .00) significantly more often. FSFI scores were significantly influenced by sexual activity in lubrication and arousal. IIEF scores were significantly determined by age in satisfaction with sexual intercourse and overall satisfaction. The morphine equivalent dose was significant higher in men than in women (38%; median = 70 mg/d, interquartile range = 43.1-170, 115.5 ± 110.3 mg/d vs median = 60 mg/d, interquartile range = 30-100.6, 76.67 ± 63.79 mg/d, P = .016) at the same mean intensity of pain (P = .54), which correlated to FSFI scores (r = -0.313, P = .01). SD is prevalent in patients with CNP and higher in men who received a significantly higher mean opioid dose at the same intensity pain level than women. The morphine equivalent dose was correlated to SD intensity

    Klinger, Christoph; Riecken, Bettina; Schmidt, Arthur; De Gottardi, Andrea; Meier, Benjamin; Bosch, Jaime; Caca, Karel


    Therapeutic anticoagulation is the standard treatment in patients with acute non-cirrhotic portal vein thrombosis (PVT). In critically ill patients, anticoagulation only may not suffice to achive rapid and stable recanalization. This study evaluates efficacy and safety of transjugular interventional therapy in acute non-cirrhotic PVT. This retrospective study includes 17 consecutive patients with acute noncirrhotic, non-malignant PVT. Main indication for interventional therapy was imminent intestinal infarction (n=10). Treatment consisted of a combination of transjugular thrombectomy, local fibrinolysis and - depending on thrombus resolution - transjugular intrahepatic portosystemic shunt. Recanalization was successful in 94.1%. One- and two-year secondary PV patency rates were 88.2%. Major complications (n=3) resolved spontaneously in all but one patient (heparin induced thrombocytopenia type 2 with intestinal infarction). Symptoms improved in all patients. However, segmental bowel resection had to be performed in two (11.8%). During a median follow-up of 28.6 months, no patient experienced portal hypertensive complications. Presence of JAK2 V617F mutation predicted both short-term and long-term technical success. Transjugular recanalization is safe and effective in patients with acute non-cirrhotic, non-malignant PVT. It should be considered especially in patients with imminent bowel infarction and low likelihood of recanalization following therapeutic anticoagulation. Patients with JAK2 mutation ought to be followed meticulously. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

  11. Leaf non-structural carbohydrate allocation and C:N:P stoichiometry in response to light acclimation in seedlings of two subtropical shade-tolerant tree species. (United States)

    Xie, Hongtao; Yu, Mukui; Cheng, Xiangrong


    Light availability greatly affects plant growth and development. In shaded environments, plants must respond to reduced light intensity to ensure a regular rate of photosynthesis to maintain the dynamic balance of nutrients, such as leaf non-structural carbohydrates (NSCs), carbon (C), nitrogen (N) and phosphorus (P). To improve our understanding of the nutrient utilization strategies of understory shade-tolerant plants, we compared the variations in leaf NSCs, C, N and P in response to heterogeneous controlled light conditions between two subtropical evergreen broadleaf shade-tolerant species, Elaeocarpus sylvestris (E. sylvestris) and Illicium henryi (I. henryi). Light intensity treatments were applied at five levels (100%, 52%, 33%, 15% and 6% full sunlight) for 30 weeks to identify the effects of reduced light intensity on leaf NSC allocation patterns and leaf C:N:P stoichiometry characteristics. We found that leaf soluble sugar, starch and NSC concentrations in E. sylvestris showed decreasing trends with reduced light intensity, whereas I. henryi presented slightly increasing trends from 100% to 15% full sunlight and then significant decreases at extremely low light intensity (6% full sunlight). The soluble sugar/starch ratio of E. sylvestris decreased with decreasing light intensity, whereas that of I. henryi remained stable. Moreover, both species exhibited increasing trends in leaf N and P concentrations but limited leaf N:P and C:P ratio fluctuations with decreasing light intensity, revealing their adaptive strategies for poor light environments and their growth strategies under ideal light environments. There were highly significant correlations between leaf NSC variables and C:N:P stoichiometric variables in both species, revealing a trade-off in photosynthesis production between leaf NSC and carbon allocation. Thus, shade-tolerant plants readjusted their allocation of leaf NSCs, C, N and P in response to light acclimation. Redundancy analysis showed

  12. Redfield Ratios in Inland Waters: Higher Biological Control of C:N:P Ratios in Tropical Semi-arid High Water Residence Time Lakes

    Directory of Open Access Journals (Sweden)

    Ng H. They


    Full Text Available The canonical Redfield C:N:P ratio for algal biomass is often not achieved in inland waters due to higher C and N content and more variability when compared to the oceans. This has been attributed to much lower residence times and higher contributions of the watershed to the total organic matter pool of continental ecosystems. In this study we examined the effect of water residence times in low latitude lakes (in a gradient from humid to a semi-arid region on seston elemental ratios in different size fractions. We used lake water specific conductivity as a proxy for residence time in a region of Eastern Brazil where there is a strong precipitation gradient. The C:P ratios decreased in the seston and bacterial size-fractions and increased in the dissolved fraction with increasing water retention time, suggesting uptake of N and P from the dissolved pool. Bacterial abundance, production and respiration increased in response to increased residence time and intracellular nutrient availability in agreement with the growth rate hypothesis. Our results reinforce the role of microorganisms in shaping the chemical environment in aquatic systems particularly at long water residence times and highlights the importance of this factor in influencing ecological stoichiometry in all aquatic ecosystems.

  13. CNP stoichiometry of a lipid-synthesising zooplankton, Calanus finmarchicus, from winter to spring bloom in a sub-Arctic sound (United States)

    Aubert, A. B.; Svensen, C.; Hessen, D. O.; Tamelander, T.


    The aim of this study was to investigate the seasonal stoichiometry of the high-latitude lipid-synthesising copepod Calanus finmarchicus and assess how this would affect dietary demands with season, ontogeny and lipid storage. C:N:P ratios in different stages (adults, copepodite V and IV), in eggs and faecal pellets as well as in bulk food (seston) was analysed in a sub-Arctic Norwegian sound (69° 47'N, 19° 19'E) from late February to mid-May 2009. The period covered the phytoplankton bloom and was divided into four sequences of the bloom based on chl a and seston C:chl a ratio variations. The calculation of the somatic elemental C:N and C:P body ratios (without the lipid storage) indicates that nearly homeostatic control in C. finmarchicus is maintained in somatic tissues within stages, while not if the lipid storage pool is included. Nutrient limitation was assessed calculating threshold elemental ratios based on the somatic body ratios and for different sets of assimilation efficiencies, and indicated a predominant C limitation that may reflect demands for lipid storage. The results suggest that stoichiometric composition and demands in such high-latitude, lipid-storing species strongly depend on stage and season, and the large contribution of storage lipids highlights the need for a two-compartment approach for lipid-synthesising species, with different dietary requirements for somatic growth and for lipid storage.

The investigations were performed in tissue sections, cytological imprint preparations as well as in homogenized tissue samples (obtained by gastroscopy). ..cap alpha../sub 1/ fetoprotein could be demonstrated by immuno-histochemistry in about 90% of the samples originating from the surroundings of gastric ulcer and the region of gastrojejunostomy after B II-resection. The RIA was positive in about 75% of the tissue samples, whereas from gastric juice only 40% of positive results could be obtained. No ..cap alpha../sub 1/ fetoprotein-activity could be demonstrated in serum samples. These investigations indicate that ..cap alpha../sub 1/ fetoprotein is not exclusively synthesized by embryonic or neoplastic tissues and also can be synthesized also by regenerating cell-systems. It may be supposed that this synthesis represents an unspecific answer to growth-stimulation.

    Transforming growth factor {beta}1 (TGF{beta}) is a tumor suppressor during the initial stage of tumorigenesis, but it can switch to a tumor promoter during neoplastic progression. Ionizing radiation (IR), both a carcinogen and a therapeutic agent, induces TGF{beta}, activation in vivo. We now show that IR sensitizes human mammary epithelial cells (HMEC) to undergo TGF{beta}-mediated epithelial to mesenchymal transition (EMT). Non-malignant HMEC (MCF10A, HMT3522 S1 and 184v) were irradiated with 2 Gy shortly after attachment in monolayer culture, or treated with a low concentration of TGF{beta} (0.4 ng/ml), or double-treated. All double-treated (IR+TGF{beta}) HMEC underwent a morphological shift from cuboidal to spindle-shaped. This phenotype was accompanied by decreased expression of epithelial markers E-cadherin, {beta}-catenin and ZO-1, remodeling of the actin cytoskeleton, and increased expression of mesenchymal markers N-cadherin, fibronectin and vimentin. Furthermore, double-treatment increased cell motility, promoted invasion and disrupted acinar morphogenesis of cells subsequently plated in Matrigel{trademark}. Neither radiation nor TGF{beta} alone elicited EMT, even though IR increased chronic TGF{beta} signaling and activity. Gene expression profiling revealed that double treated cells exhibit a specific 10-gene signature associated with Erk/MAPK signaling. We hypothesized that IR-induced MAPK activation primes non-malignant HMEC to undergo TGF{beta}-mediated EMT. Consistent with this, Erk phosphorylation were transiently induced by irradiation, persisted in irradiated cells treated with TGF{beta}, and treatment with U0126, a Mek inhibitor, blocked the EMT phenotype. Together, these data demonstrate that the interactions between radiation-induced signaling pathways elicit heritable phenotypes that could contribute to neoplastic progression.

  18. Vitality training-A mindfulness- and acceptance-based intervention for chronic pain. (United States)

    Zangi, Heidi A; Haugli, Liv


    Chronic non-malign pain has a substantial impact on all parts of an individual's life. Mindfulness- and acceptance- based interventions are increasingly offered to help people manage their pain and strengthening their health promoting resources. In this paper, we present a mindfulness- and acceptance-based intervention, the Vitality Training Programme (VTP), to mitigating pain and accompanying symptoms and increasing pain coping abilities. Based on a clinical case presentation, we discuss how the VTP can help individuals to live a better life with pain. The VTP has been evaluated in two randomised controlled trials and two qualitative studies. Existing evidence is presented. Finally, based on a recently published theoretical model, we present some possible common explanatory mechanisms across various mindfulness- and acceptance-based interventions that might also apply to the VTP.

  19. Influence of worldview on health care choices among persons with chronic pain. (United States)

    Buck, Tina; Baldwin, Carol M; Schwartz, Gary E


    The aim of this research was to examine relationships between the Pepperian worldviews of people with chronic pain and the health care choices that they make. A convenience sample survey was done. University Medical Center Pain Clinic, Tucson, Arizona. Men and women patients (n = 96) with nonmalignant chronic pain. World Hypothesis Scale; Health Care Choice List. Findings indicate that the combination of age and formistic worldview are statistically significant predictors of conventional health care choices by participants in this study. Older patients and persons with a predominantly formistic worldview were less likely to use complementary and alternative medicine (CAM) as a choice among this sample with chronic nonmalignant pain. Borderline significant associations were noted between persons with formistic or mechanistic worldviews and conventional health care choices, and persons with contextualistic, organismic, or equal scores in two worldview categories and CAM health care choices. Although rates of CAM use did not significantly differ from conventional choices, the prevalence rate for CAM use was high (55.2%) based on national findings. Results of this study provide a link to understanding how underlying philosophies can contribute to the reasons people with chronic pain make health care decisions. Further exploration of worldviews might very well contribute to best practices for consumer health care by engaging in communication styles and belief systems consistent with consumers' personal schemas.

    Sasaki, Sho; Kawarazaki, Hiroo; Hasegawa, Takeshi; Shima, Hideaki; Naganuma, Toshihide; Shibagaki, Yugo


    The renal prognosis of post-renal acute kidney injury (PoR-AKI) has not been verified so far. The objective of this study was to assess the association of baseline anemia with long-term renal prognosis in patients with PoR-AKI. We performed a multicenter retrospective cohort study. Consecutive adult patients from December 2006 to February 2010, who met the requirements as mentioned in the definition of PoR-AKI, were included. Patients without data on baseline renal function and at 6 months after PoR-AKI were excluded. We set baseline hemoglobin (Hb) level (g/dl) as the main exposure to be tested. The main outcome measure was long-term renal prognosis as determined by the difference between proximate estimated glomerular filtration rate (eGFR) at 6 months after diagnosis of PoR-AKI and baseline eGFR prior to the occurrence of the present PoR-AKI (ΔeGFR after 6 months) using the general linear model. We included 136 patients with PoR-AKI. The most frequent cause of PoR-AKI was malignancy, accounting for 39.0% (n = 53) of cases. Multivariate analysis adjusted for possible confounders showed that ΔeGFR after 6 months significantly changed by -4.28 ml/min/1.73 m2 for every 1 g/dl lower Hb at diagnosis (95% CI 1.86-6.69, p < 0.01). An additional multivariate analysis that was stratified by the presence or absence of malignancy as the cause of PoR-AKI yielded the same significant result only in the stratum of the nonmalignant cause of PoR-AKI. Patients with a nonmalignant cause of PoR-AKI who have baseline anemia may have poor long-term renal prognosis. In these cases, close observation of renal function after renal recovery may be required. © 2016 S. Karger AG, Basel.

  1. Safety, efficacy, and response predictors of anticoagulation for the treatment of nonmalignant portal-vein thrombosis in patients with cirrhosis: a propensity score matching analysis

    Full Text Available Background/AimsPortal-vein thrombosis (PVT develops in 10-25% of cirrhotic patients and may aggravate portal hypertension. There are few data regarding the effects of anticoagulation on nonmalignant PVT in liver cirrhosis. The aim of this study was to elucidate the safety, efficacy, and predictors of response to anticoagulation therapy in cirrhotic patients.MethodsPatients with liver cirrhosis and nonmalignant PVT were identified by a hospital electronic medical record system (called BESTCARE. Patients with malignant PVT, Budd-Chiari syndrome, underlying primary hematologic disorders, or preexisting extrahepatic thrombosis were excluded from the analysis. Patients were divided into two groups (treatment and nontreatment, and propensity score matching analysis was performed to identify control patients. The sizes of the thrombus and spleen were evaluated using multidetector computed tomography.ResultsTwenty-eight patients were enrolled in this study between 2003 and 2014: 14 patients who received warfarin for nonmalignant PVT and 14 patients who received no anticoagulation. After 112 days of treatment, 11 patients exhibited significantly higher response rates (complete in 6 and partial in 5 compared to the control patients, with decreases in thrombus size of >30%. Compared to nonresponders, the 11 responders were older, and had a thinner spleen and fewer episodes of previous endoscopic variceal ligations, whereas pretreatment liver function and changes in prothrombin time after anticoagulation did not differ significantly between the two groups. Two patients died after warfarin therapy, but the causes of death were not related to anticoagulation.ConclusionsWarfarin can be safely administered to cirrhotic patients with nonmalignant PVT. The presence of preexisting portal hypertension is a predictor of nonresponse to anticoagulation.

    Background and purpose: In HIV infected patients, MRI cannot reliably differentiate between central nervous system (CNS) lymphoma and non-malignant CNS lesions, particularly cerebral toxoplasmosis (CTOX). This study prospectively investigates the utility of FDG PET-CT and magnetic resonance spectroscopy (MRS) in discriminating CNS lymphoma from non-malignant CNS lesions in HIV infected patients, and assesses the ability of FDG PET-CT to guide the use of early brain biopsy. Methods: 10 HIV patients with neurological symptoms and contrast enhancing lesions on MRI were commenced on anti-toxoplasmosis therapy before undergoing FDG PET-CT and MRS. Brain biopsies were sought in those with FDG PET-CT suggestive of CNS lymphoma, and in those with a negative FDG PET-CT scan who failed to respond to therapy. Final diagnosis was based on histology or treatment response. Results: Two patients were confirmed to have CNS lymphoma and FDG PET-CT was consistent with this diagnosis in both. Six patients had cerebral toxoplasmosis in all of whom FDG PET-CT was consistent with non-malignant disease. One patient had progressive multifocal leukoencephalopathy (PML), FDG PET-CT was equivocal. One patient had a haemorrhagic brain metastasis and FDG PET-CT wrongly suggested non-malignant disease. MRS was performed successfully in eight subjects: three results were suggestive of CNS lymphoma (one true positive, two false positive), four suggested CTOX (two false negative, two true negative), one scan was equivocal. Conclusion: FDG PET-CT correctly identified all cases of CNS lymphoma and CTOX, supporting its use in this situation. MRS was unhelpful in our cohort.

    Umbilical cord blood (UCB) from an human leucocyte antigen (HLA)-identical sibling can be used for transplantation of patients with malignant and non-malignant diseases. However, the low cellular content of most UCB units represents a limitation to this approach. An option to increase cell dose is to harvest bone marrow (BM) cells from the same donor and infuse them along with the UCB. We studied 156 children who received such a combined graft between 1992 and 2011. Median age was 7 years and 78% of patients (n = 122) were transplanted for non-malignant diseases, mainly haemoglobinopathies. Acute leukaemia (n = 26) was the most frequent malignant diagnosis. Most patients (91%) received myeloablative conditioning. Median donor age was 1·7 years, median infused nucleated cell dose was 24·4 × 10(7) /kg and median follow-up was 41 months. Sixty-days neutrophil recovery occurred in 96% of patients at a median of 17 d. The probabilities of grade-II-IV acute and chronic graft-versus-host disease (GVHD) were 19% and 10%, respectively. Four-year overall survival was 90% (68% malignant; 97% non-malignant diseases) with 3% probability of death. In conclusion, combined UCB and BM transplantation from an HLA-identical sibling donor is an effective treatment for children with malignant and non-malignant disorders with high overall survival and low incidence of GVHD. © 2014 John Wiley & Sons Ltd.

  5. The effects of erythropoietin signaling on telomerase regulation in non-erythroid malignant and non-malignant cells

    Uziel, Orit; Kanfer, Gil; Beery, Einat; Yelin, Dana; Shepshelovich, Daniel; Bakhanashvili, Mary; Nordenberg, Jardena; Lahav, Meir


    Highlights: • We assumed that some of erythropoietin adverse effects may be mediated by telomerase activity. • EPO administration increased telomerase activity, cells proliferation and migration. • The inhibition of telomerase modestly repressed the proliferative effect of erythropoietin. • Telomere shortening caused by long term inhibition of the enzyme totally abolished that effect. • This effect was mediated via the Lyn–AKT axis and not by the canonical JAK2–STAT pathway. - Abstract: Treatment with erythropoietin (EPO) in several cancers is associated with decreased survival due to cancer progression. Due to the major importance of telomerase in cancer biology we hypothesized that some of these effects may be mediated through EPO effect on telomerase. For this aim we explored the possible effects of EPO on telomerase regulation, cell migration and chemosensitivity in non-erythroid malignant and non-malignant cells. Cell proliferation, telomerase activity (TA) and cell migration increased in response to EPO. EPO had no effect on cancer cells sensitivity to cisplatinum and on the cell cycle status. The inhibition of telomerase modestly repressed the proliferative effect of EPO. Telomere shortening caused by long term inhibition of the enzyme abolished the effect of EPO, suggesting that EPO effects on cancer cells are related to telomere dynamics. TA was correlated with the levels of Epo-R. The increase in TA was mediated post-translationally through the Lyn-Src and not the canonical JAK2 pathway

  6. Occupational exposure to respirable crystalline silica and chronic non-malignant renal disease: systematic review and meta-analysis. (United States)

    Möhner, Matthias; Pohrt, Anne; Gellissen, Johannes


    While occupational exposure to respirable silica is known to lead to lung disease, most notably silicosis, its association with chronic kidney disease is unclear. This review explores the association between occupational exposure to respirable silica and chronic non-malignant renal disease such as glomerulonephritis. The evidence has been collected and compiled. Possible sources of bias are thoroughly discussed. Cohort studies with silica exposure and case-control studies of renal disease were searched in PubMed until January 2015. Two authors independently abstracted data; any disagreement was resolved by consulting a third reviewer. A meta-analysis was performed to evaluate the association to silica exposure. A total of 23 cohort and four case-control studies were included in the analysis. The meta-analysis of cohort studies yielded elevated overall SMRs for renal disease. Some studies, however, included dose-response analyses, most of which did not show a positive trend. The approaches and results of the case-control studies were very heterogeneous. While the studies of cohorts exposed to silica found elevated SMRs for renal disease, no clear evidence of a dose-response relationship emerged. The elevated risk may be attributed to diagnostic and methodological issues. In order to permit a reliable estimation of a possible causal link, exposed cohorts should be monitored for renal disease, as the information from mortality studies is hardly reliable in this field.

  7. Non-myeloablative allogeneic stem cell transplantation focusing on immunotherapy of life-threatening malignant and non-malignant diseases. (United States)

    Slavin, S; Nagler, A; Shapira, M; Panigrahi, S; Samuel, S; Or, A


    Allogeneic bone marrow transplantation (BMT) represents an important therapeutic tool for treatment of otherwise incurable malignant and non-malignant diseases. Until recently, myeloablative regimens were considered mandatory for eradication of all undesirable host-derived hematopoietic elements. Our preclinical and ongoing clinical studies indicated that much more effective eradication of host immunohematopoietic system cells could be achieved by adoptive allogeneic cell therapy with donor lymphocyte infusion (DLI) following BMT. Thus, eradication of blood cancer cells, especially in patients with CML can be frequently accomplished despite complete resistance of such tumor cells to maximally tolerated doses of chemoradiotherapy. Our cumulative experience suggested that graft versus leukemia (GVL) effects might be a useful tool for eradication of otherwise resistant tumor cells of host origin. The latter working hypothesis suggested that effective BMT procedures may be accomplished without lethal conditioning of the host, using new well tolerated non-myeloablative regimen, thus possibly minimizing immediate and late side effects related to myeloablative procedures considered until recently mandatory for conditioning of BMT recipients. Recent clinical data that will be presented suggests that safe non-myeloablative stem cell transplantation (NST), with no major toxicity can replace the conventional BMT. Thus, NST may provide an option for cure for a large spectrum of clinical indications in children and elderly individuals without lower or upper age limit, while minimizing procedure-related toxicity and mortality.

  9. Sexual pain. (United States)

    Boardman, Lori A; Stockdale, Colleen K


    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.

  10. Revisiting the concept of Redfield ratios applied to plankton stoichiometry - Addressing model uncertainties with respect to the choice of C:N:P ratios for phytoplankton (United States)

    Kreus, Markus; Paetsch, Johannes; Grosse, Fabian; Lenhart, Hermann; Peck, Myron; Pohlmann, Thomas


    Ongoing Ocean Acidification (OA) and climate change related trends impact on physical (temperature), chemical (CO2 buffer capacity) and biological (stoichiometric) properties of the marine environment. These threats affect the global ocean but they appear particularly pronounced in marginal and shelf seas. Marine biogeochemical models are often used to investigate the impacts of climate change and changes in OA on the marine system as well as its exchange with the atmosphere. Different studies showed that both the structural composition of the models and the elemental ratios of particulate organic matter in the surface ocean affect the key processes controlling the ocean's efficiency storing atmospheric excess carbon. Recent studies focus on the variability of the elemental ratios of phytoplankton and found that the high plasticity of C:N:P ratios enables the storage of large amounts of carbon by incorporation into carbohydrates and lipids. Our analysis focuses on the North Sea, a temperate European shelf sea, for the period 2000-2014. We performed an ensemble of model runs differing only in phytoplankton stoichiometry, representing combinations of C:P = [132.5, 106, 79.5] and N:P=[20, 16, 12] (i.e., Redfield ratio +/- 25%). We examine systematically the variations in annual averages of net primary production (NPP), net ecosystem production in the upper 30 m (NEP30), export production below 30 m depth (EXP30), and the air-sea flux of CO2 (ASF). Ensemble average fluxes (and standard deviations) resulted in NPP = 15.4 (2.8) mol C m-2 a-1, NEP30 = 5.4 (1.1) mol C m-2 a-1, EXP30 = 8.1 (1.1) mol C m-2 a-1 and ASF = 1.1 (0.5) mol C m-2 a-1. All key parameters exhibit only minor variations along the axis of constant C:N, but correlate positively with increasing C:P and decreasing N:P ratios. Concerning regional differences, lowest variations in local fluxes due to different stoichiometric ratios can be found in the shallow southern and coastal North Sea. Highest

  11. Predominant Non-additive Effects of Multiple Stressors on Autotroph C:N:P Ratios Propagate in Freshwater and Marine Food Webs (United States)

    Villar-Argaiz, Manuel; Medina-Sánchez, Juan M.; Biddanda, Bopaiah A.; Carrillo, Presentación


    A continuing challenge for scientists is to understand how multiple interactive stressor factors affect biological interactions, and subsequently, ecosystems–in ways not easily predicted by single factor studies. In this review, we have compiled and analyzed available research on how multiple stressor pairs composed of temperature (T), light (L), ultraviolet radiation (UVR), nutrients (Nut), carbon dioxide (CO2), dissolved organic carbon (DOC), and salinity (S) impact the stoichiometry of autotrophs which in turn shapes the nature of their ecological interactions within lower trophic levels in streams, lakes and oceans. Our analysis from 66 studies with 320 observations of 11 stressor pairs, demonstrated that non-additive responses predominate across aquatic ecosystems and their net interactive effect depends on the stressor pair at play. Across systems, there was a prevalence of antagonism in freshwater (60–67% vs. 47% in marine systems) compared to marine systems where synergism was more common (49% vs. 33–40% in freshwaters). While the lack of data impeded comparisons among all of the paired stressors, we found pronounced system differences for the L × Nut interactions. For this interaction, our data for C:P and N:P is consistent with the initial hypothesis that the interaction was primarily synergistic in the oceans, but not for C:N. Our study found a wide range of variability in the net effects of the interactions in freshwater systems, with some observations supporting antagonism, and others synergism. Our results suggest that the nature of the stressor pairs interactions on C:N:P ratios regulates the “continuum” commensalistic-competitive-predatory relationship between algae and bacteria and the food chain efficiency at the algae-herbivore interface. Overall, the scarce number of studies with even more fewer replications in each study that are available for freshwater systems have prevented a more detailed, insightful analysis. Our findings

Patients with renal or liver impairment need specific consideration, as most analgesics rely on either or both for their metabolism and excretion. Recent evidence-based guidelines and the systematic reviews that have informed their recommendations. The principles of the WHO (World Health Organisation) analgesic ladder are commonly endorsed as a structured approach to the management of pain. For neuropathic pain, the efficacy of different agents is similar and choice of drug more guided by side effects, drug interactions and cost. Evidence supporting the WHO analgesic ladder is disputed and alternatives suggested, but no overwhelming evidence for an alternative approach exists to date. Alternative approaches to the WHO analgesic ladder, new analgesic agents, e.g. rapid onset oral/intranasal fentanyl. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Patients with opioid addiction who receive prescription opioids for treatment of nonmalignant chronic pain present a therapeutic challenge. Fifty-four participants with chronic pain and opioid addiction were randomized to receive methadone or buprenorphine/naloxone. At the 6-month follow-up examination, 26 (48.1%) participants who remained in the study noted a 12.75% reduction in pain (P = 0.043), and no participants in the methadone group compared to 5 in the buprenorphine group reported illicit opioid use (P = 0.039). Other differences between the two conditions were not found. Long-term, low-dose methadone or buprenorphine/naloxone treatment produced analgesia in participants with chronic pain and opioid addiction.

    Understanding prostate stem cells may provide insight into the origin of prostate cancer. Primary cells have been cultured from human prostate tissue but they usually survive only 15-20 population doublings before undergoing senescence. We report here that RC-170N/h/clone 7 cells, a clonal cell line from hTERT-immortalized primary non-malignant tissue-derived human prostate epithelial cell line (RC170N/h), retain multipotent stem cell properties. The RC-170N/h/clone 7 cells expressed a human embryonic stem cell marker, Oct-4, and potential prostate epithelial stem cell markers, CD133, integrin α2β1 hi and CD44. The RC-170N/h/clone 7 cells proliferated in KGM and Dulbecco's Modified Eagle Medium with 10% fetal bovine serum and 5 μg/ml insulin (DMEM + 10% FBS + Ins.) medium, and differentiated into epithelial stem cells that expressed epithelial cell markers, including CK5/14, CD44, p63 and cytokeratin 18 (CK18); as well as the mesenchymal cell markers, vimentin, desmin; the neuron and neuroendocrine cell marker, chromogranin A. Furthermore the RC170 N/h/clone 7 cells differentiated into multi tissues when transplanted into the sub-renal capsule and subcutaneously of NOD-SCID mice. The results indicate that RC170N/h/clone 7 cells retain the properties of multipotent stem cells and will be useful as a novel cell model for studying the mechanisms of human prostate stem cell differentiation and transformation

  3. Factors predicting the duration of adrenal insufficiency in patients successfully treated for Cushing disease and nonmalignant primary adrenal Cushing syndrome. (United States)

    Prete, Alessandro; Paragliola, Rosa Maria; Bottiglieri, Filomena; Rota, Carlo Antonio; Pontecorvi, Alfredo; Salvatori, Roberto; Corsello, Salvatore Maria


    Successful treatment of Cushing syndrome causes transient or permanent adrenal insufficiency deriving from endogenous hypercortisolism-induced hypothalamus-pituitary-adrenal-axis suppression. We analyzed pre-treatment factors potentially affecting the duration of adrenal insufficiency. We conducted a retrospective analysis on patients successfully treated for Cushing disease (15 patients) who underwent transsphenoidal surgery, and nonmalignant primary adrenal Cushing syndrome (31 patients) who underwent unilateral adrenalectomy, divided into patients with overt primary adrenal Cushing syndrome (14 patients) and subclinical primary adrenal Cushing syndrome (17 patients). Epidemiological data, medical history, and hormonal parameters depending on the etiology of hypercortisolism were collected and compared to the duration of adrenal insufficiency. The median duration of follow-up after surgery for Cushing disease and primary adrenal Cushing syndrome was 70 and 48 months, respectively. In the Cushing disease group, the median duration of adrenal insufficiency after transsphenoidal surgery was 15 months: younger age at diagnosis and longer duration of signs and symptoms of hypercortisolism before diagnosis and surgery were associated with longer duration of adrenal insufficiency. The median duration of adrenal insufficiency was 6 months for subclinical primary adrenal Cushing syndrome and 18.5 months for overt primary adrenal Cushing syndrome. The biochemical severity of hypercortisolism, the grade of hypothalamus-pituitary-adrenal-axis suppression, and treatment with ketoconazole before surgery accounted for longer duration of adrenal insufficiency. In patients with Cushing disease, younger age and delayed diagnosis and treatment predict longer need for glucocorticoid replacement therapy after successful transsphenoidal surgery. In patients with primary adrenal Cushing syndrome, the severity of hypercortisolism plays a primary role in influencing the duration of

  4. Continuous Ecosystem Stoichiometry (C:N:P) in a Large Spring-fed River Reveals Decoupled N and P Assimilatory Dynamics (United States)

    Cohen, M. J.; Douglass, R. L.; Martin, J. B.; Thomas, R. G.; Heffernan, J. B.; Foster, C. R.


    Diel variation in solutes offers insight into lotic ecosystem processes. Diel variation in dissolved oxygen (DO) is the standard method to estimate aquatic primary production (C fixation). Recently, diel variation in nitrate concentration was used to infer rates and pathways of N processing. From coupled C and N measurements, stoichiometric ratios of nutrient assimilation can be obtained, and variation therein linked back to environmental drivers and ecological changes. Here we present data obtained using an in situ phosphate sensor (Cycle-P, WetLabs, Philomath OR) that permits coupled high frequency C, N and P measurements. We collected hourly samples over 3 two-week deployments in the Ichetucknee River, a large (Q ~ 10 m3 s-1), productive (GPP ~ 6 g C m-2 d-1), entirely spring-fed river in north Florida. We observed average soluble reactive P (SRP) concentrations of 44, 41 and 45 µg/L for Dec-09, Feb-10 and Apr-10, respectively, and marked diel variation that averaged 6.7±0.9 µg/L. Observed river concentrations were consistently at or below the flow-weighted average input concentration of the 6 main springs that feed the river (49 µg/L) suggesting net SRP removal over the 5 km reach. Removal from co-precipitation with calcite or Fe-oxides is unlikely since variation in Fe and Ca is smaller than, and out of phase with, P variation. Since internal stores are presumed to be at steady-state given conditions of constant discharge, the balance of P export likely occurs as organic matter. Based on discharge during each deployment, diel variation of P concentrations indicate system-wide assimilation of 1505 ± 423 g P d-1, or 8.0 ± 2.3 mg P m-2 d-1 over the 17 ha of benthic surface area. Contemporaneous measurements of DO and nitrate implied average ecosystem stoichiometry (C:N:P) of 267:14:1, consistent with production dominated by submerged aquatic macrophytes rather than algae and other microflora. Of particular interest is the observation that diel variation in

    Tran, Van; Little, Mark P. [National Cancer Institute, Radiation Epidemiology Branch, Rockville, MD (United States)


    Murine experiments were conducted at the JANUS reactor in Argonne National Laboratory from 1970 to 1992 to study the effect of acute and protracted radiation dose from gamma rays and fission neutron whole body exposure. The present study reports the reanalysis of the JANUS data on 36,718 mice, of which 16,973 mice were irradiated with neutrons, 13,638 were irradiated with gamma rays, and 6107 were controls. Mice were mostly Mus musculus, but one experiment used Peromyscus leucopus. For both types of radiation exposure, a Cox proportional hazards model was used, using age as timescale, and stratifying on sex and experiment. The optimal model was one with linear and quadratic terms in cumulative lagged dose, with adjustments to both linear and quadratic dose terms for low-dose rate irradiation (<5 mGy/h) and with adjustments to the dose for age at exposure and sex. After gamma ray exposure there is significant non-linearity (generally with upward curvature) for all tumours, lymphoreticular, respiratory, connective tissue and gastrointestinal tumours, also for all non-tumour, other non-tumour, non-malignant pulmonary and non-malignant renal diseases (p < 0.001). Associated with this the low-dose extrapolation factor, measuring the overestimation in low-dose risk resulting from linear extrapolation is significantly elevated for lymphoreticular tumours 1.16 (95% CI 1.06, 1.31), elevated also for a number of non-malignant endpoints, specifically all non-tumour diseases, 1.63 (95% CI 1.43, 2.00), non-malignant pulmonary disease, 1.70 (95% CI 1.17, 2.76) and other non-tumour diseases, 1.47 (95% CI 1.29, 1.82). However, for a rather larger group of malignant endpoints the low-dose extrapolation factor is significantly less than 1 (implying downward curvature), with central estimates generally ranging from 0.2 to 0.8, in particular for tumours of the respiratory system, vasculature, ovary, kidney/urinary bladder and testis. For neutron exposure most endpoints, malignant and

    Full Text Available Pain, which afflicts up to 20% of the population at any time, provides both a massive therapeutic challenge and a route to understanding mechanisms in the nervous system. Specialised sensory neurons (nociceptors signal the existence of tissue damage to the central nervous system (CNS, where pain is represented in a complex matrix involving many CNS structures. Genetic approaches to investigating pain pathways using model organisms have identified the molecular nature of the transducers, regulatory mechanisms involved in changing neuronal activity, as well as the critical role of immune system cells in driving pain pathways. In man, mapping of human pain mutants as well as twin studies and association studies of altered pain behaviour have identified important regulators of the pain system. In turn, new drug targets for chronic pain treatment have been validated in transgenic mouse studies. Thus, genetic studies of pain pathways have complemented the traditional neuroscience approaches of electrophysiology and pharmacology to give us fresh insights into the molecular basis of pain perception.

  7. Validation of a Modified German Version of the Brief Pain Inventory for Use in Nursing Home Residents with Chronic Pain. (United States)

    The Brief Pain Inventory (BPI) has been psychometrically evaluated worldwide in adult patients with cancer-related and chronic pain in several languages, but never in nursing home residents with chronic pain. To address this gap, we evaluated the validity of a modified version of the BPI, the BPI for nursing home residents (BPI-NHR) in individuals who resided in German nursing homes. One analytic sample included 137 nursing home residents (mean age, 83.3 years; SD, 8.0 years) without any missing values. An extended sample also included individuals with previous missing values that were substituted with the personal mean (n = 163; mean age, 83.3 years; SD, 8.3 years). Principal axis factoring with oblimin rotation was used to compute the final 2-factor solution for the substituted sample. These factors explained 71.7% of the variance. Internal consistency was calculated using Cronbach α, and showed excellent results. Concurrent validity was tested using nonparametric correlation analyses of the BPI-NHR with the pain medication scale. The present findings support the reliability and validity of the BPI-NHR for very old nursing home residents. Further evaluation of this measure is needed to examine face validity and the effect of multimorbidity on pain interference with function. In this article we present psychometric properties of the BPI originally developed to assess cancer pain, extended to measure chronic nonmalignant pain in younger and middle-aged patients, and now further developed to measure pain intensity and interference with function among very old nursing home residents. Thus, the BPI-NHR might assist clinicians and researchers interested in assessment of pain intensity and interference in elderly individuals who reside in nursing homes.

    The 92 children aged 12-17 years were examined with the purpose to study the links between carbohydrate and lipid metabolic abnormalities and non-malignant thyroid disorders in descendants of the Chernobyl accident survivors. Clinical, anthropometrical studies and hormonal assays were applied. Carbohydrate and lipid metabolic abnormalities were revealed in every third case of thyroid disease. It confirms our supposition of such a possibility being due to the fact that radiation impact even in low doses can result in pronounced metabolic disorders lading to entire endocrine disregulation.

  11. Monoamine oxidase inhibitors l-deprenyl and clorgyline protect nonmalignant human cells from ionising radiation and chemotherapy toxicity.

    LENUS (Irish Health Repository)

    Seymour, C B


    l-Deprenyl (R-(-)-deprenyl, selegiline) is an inhibitor of monoamine oxidase-B (MAO-B) that is known to protect nerve cells from a variety of chemical and physical insults. As apoptosis is a common mechanism of radiation-induced cell death, the effect of l-deprenyl on the survival of cultured cells and tissue explants was studied following exposure to gamma radiation. The results obtained were compared with the effects of the less-selective MAO-B inhibitor pargyline and the MAO-A inhibitor clorgyline. l-Deprenyl at a concentration of 10(-9) M protected the nontumorigenic cell line (HaCaT) and normal human urothelial explants from the effects of cobalt-60 gamma radiation, but did not protect tumorigenic human cell lines HaCaT-ras, HPV-transfected human keratinocytes (HPV-G cells), or PC3. Human bladder carcinoma explants were not protected. Clorgyline showed a smaller protective effect of normal cells, whereas pargyline had no effect. Radiation-induced delayed effects (genomic instability measured as delayed cell death) were prevented in normal cells by l-deprenyl but, interestingly, deprenyl appeared to increase the amount of delayed death in the tumorigenic cell lines. Studies using l-deprenyl prior to the exposure of nonmalignant cells to cisplatin showed that cell death due to this agent was also reduced. Treatment of cultures of nontumorigenic cells with l-deprenyl or clorgyline significantly increased the levels of the protein Bcl-2 following irradiation, but there was no such effect on the already-elevated levels of this protein in the tumour samples. Since the Bcl-2 has been shown to be an inhibitor of apoptosis or programmed cell death, this would imply that the protective effects of l-deprenyl and clorgyline involve activation of antiapoptotic pathways within the normal cell. This hypothesis is supported by data showing reduced levels of apoptosis in HaCAT cells and in normal bladder explant cultures following treatment with l-deprenyl.

    Giuseppe Re


    Full Text Available Neuropathic pain is the expression of a dysfunction or primary lesion of a nerve in the peripheral or central nervous system, or both, rather than the biological signal transmitted by the nerve following peripheral nociceptor activation. It represents about 20% of all painful syndromes, with an estimated prevalence of 1.5%, however is actual incidence is hard to pinpoint due to the difficulties encountered in distinguishing it from chronic pain, of which it represents a significant percentage, on account of the not infrequent concurrence of conditions. It is crucial to recognise the variety of symptoms with which it can present: these can be negative and positive and, in turn, motor, sensitive and autonomic. In public health terms, it is important to emphasise that the diagnosis of neuropathic pain does not in most cases require sophisticated procedures and does not therefore weigh on health expenditure. In clinical practice, a validated scale (the LANSS is mentioned is useful for identifying patients presenting neuropathic pain symptoms. Therapy is based on three categories of medication: tricyclic antidepressants, anti-epileptics and opioids at high doses: neuropathic pain has a bad reputation for often resisting common therapeutic approaches and responding less well that nociceptor pain to monotherapy. Therapeutic strategies are all the more adequate the more they are based on symptoms and therefore on the pain generation mechanisms, although the recommendations are dictated more by expert opinions that double-blind randomised trials.

  18. Reduced-intensity conditioning for the treatment of malignant and life-threatening non-malignant disorders. (United States)

    Slavin, Shimon; Aker, Mehmet; Shapira, Michael Y; Resnick, Igor; Bitan, Menachem; Or, Reuven


    Allogeneic bone marrow or blood stem cell transplantation (BMT) represents an important therapeutic tool for the treatment of an otherwise incurable broad spectrum of malignant and non-malignant diseases. Until recently, BMT was used primarily to replace a malignant, genetically abnormal or deficient immunohematopoietic compartment and therefore, highly toxic myeloablative regimens were considered mandatory for more effective eradication of all undesirable host-derived hematopoietic cells, including stem cells and their progeny. Our preclinical and ongoing clinical studies indicated that much more effective eradication of host immunohematopoietic system cells can be mediated by donor lymphocytes in the process of adoptive allogeneic cell therapy following BMT. Thus, eradication of all malignant cells, especially in patients with CML and, to a lesser extent, in patients with other hematologic malignancies can be accomplished despite complete resistance of puch tumor cells to maximally tolerated doses of chemoradiotherapy. Our cumulative experience suggested that graft-versus-malignancy effects might be used as a tool for eradication of otherwise resistant tumor cells of host origin. We speculated that the therapeutic benefit of BMT may be improved by using safer conditioning for engraftment of donor stem cells induce host-versus-graft unresponsiveness to enable engraftment of donor lymphocytes for subsequent induction of graft-versus-malignancy effects, or even graft-versus-autoimmunity and graft-versus-genetically abnormal cells. In other words, focusing on more selective and smarter rather than stronger modalities. Effective BMT procedures may be accomplished without lethal conditioning of the host, using a new, well-tolerated and user-friendly non-myeloablative regimen, thus eliminating or minimizing immediate and late procedure-related toxicity and mortality. It appears that initial induction of graft tolerance, mediated by engraftment of donor stem cells, leads

  14. Chronic neck pain and anxiety-depression: prevalence and associated risk factors. (United States)

    Elbinoune, Imane; Amine, Bouchra; Shyen, Siham; Gueddari, Sanae; Abouqal, Redouane; Hajjaj-Hassouni, Najia


    Chronic pain in rheumatology often has a psychic impact, which may aggravate the daily life of patients. Chronic neck pain, as an example, is a frequent reason for consultation. The aim of this study is to assess the prevalence of anxiety and depression in patients with neck pain, and identify risk factors associated with their occurrence. It was a cross-sectional study that concerned 80 patients with neck pain lasting for more than 3 months, seen in rheumatology consultations. All patients with symptomatic neck pain or psychological history or receiving psychotropic medication were excluded from the study. For each patient, we determined the sociodemographic characteristics and clinical ones. The anxious and depressed mood was assessed by the Hospital Anxiety and Depression Scale (HAD). Of the 80 patients, 67 (83.8%) were women. Average age of our population was 51.8± 11.8 years. Median duration of symptoms was 24 months [12, 48]. Mean VAS pain was 63.9% ± 12.5, mean VAS functional discomfort was 60.9% ± 14.2 and mean VAS disability was 59.8% ± 14.7. 32 patients (40%) were illiterate and 18 (22.5%) had university level. Anxiety was found in 54 (68.4%) and 44 (55.7%) patients were depressed. In univariate analysis, VAS disability was statistically linked to anxiety (OR:1.05; 95%CI: 1.01-1.08; p = 0.02). The cervicobrachial neuralgia (CBN) was significantly associated with depression (OR: 3.33; 95%CI: 1.20-9.23; p = 0.02). Primary education level had a statistically significant relationship with anxiety (OR: 6.00; 95%CI: 1.03-34.84; p = 0.04) and depression (OR: 5.00; 95%CI: 1.09-22.82; p = 0.03). In multivariate analysis, VAS disability and CBN were independently associated with anxiety and depression respectively. This study underlines the fact that anxiety and depression are prevalent in chronic neck pain (CNP) patients. Furthermore, disability and CBN which are linked to CNP can predict which patient is at higher risk of psychological distress.

  15. Neonatal pain (United States)

    Walker, Suellen M


    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.

  17. Efficacy of transverse tripolar stimulation for relief of chronic low back pain: results of a single center. (United States)

    Slavin, K V; Burchiel, K J; Anderson, V C; Cooke, B


    The goal of this study was to evaluate the efficacy of the transverse tripolar spinal cord stimulation system (TTS) in providing relief of low back pain in patients with chronic non-malignant pain. Transverse tripolar electrodes were implanted in the lower thoracic region (T(8-9) to T(12)-L(1)) in 10 patients with chronic neuropathic pain, all of whom reported a significant component of low back pain in combination with unilateral or bilateral leg pain. One patient reported inadequate pain relief during the trial and was not implanted with a permanent generator. A visual analogue scale of low back pain showed a nonsignificant decrease from 64 +/- 19 to 47 +/- 30 (p = 0.25; paired t test) after 1 month of stimulation. Similarly, functional disability evaluated using Oswestry Low Back Pain Questionnaire was not improved (p = 0. 46; paired t test). We conclude that chronic low back pain is not particularly responsive to the transverse stimulation provided by the TTS system. Copyright 2000 S. Karger AG, Basel

  18. Dealing with grief related to loss by death and chronic pain: An integrated theoretical framework. Part 1

    Directory of Open Access Journals (Sweden)

    Bodil Furnes


    Full Text Available Bodil Furnes, Elin DysvikUniversity of Stavanger, Faculty of Social Sciences, Department of Health Studies, Stavanger, NorwayObjective: Based on the present authors’ research and several approaches to grief related to loss by death and nonmalignant chronic pain, the paper suggests a new integrated theoretical framework for intervention in clinical settings.Methods: An open qualitative review of the literature on grief theories was performed searching for a new integrated approach in the phenomenological tradition. We then investigated the relationship between grief, loss and chronic nonmalignant pain, looking for main themes and connections and how these could be best understood in a more holistic manner.Results: Two main themes were formulated, “relearning the world” and “adaptation”. Between these themes a continuous movement emerged involving experience such as: “despair and hope”, “lack of understanding and insight”, “meaning disruption and increased meaning”, and “bodily discomfort and reintegrated body”. These were identified as paired subthemes.Conclusions: Grief as a distinctive experience means that health care must be aimed at each individual experience and situation. Grief experience and working with grief are considered in terms of relearning the world while walking backwards and living forwards, as described in our integrated model. We consider that this theoretical framework regarding grief should offer an integrated foundation for health care workers who are working with people experiencing grief caused by death or chronic pain.Keywords: health care, loss, grief

    In emergency departments, chest pain is one of the leading motives of consultation. We thus consider it important to review aspects such as its classification, causes, and clinical profiles. Initial assessment should include a full clinical history comprising thorough anamnesis and physical examination. Adequate interpretation of auxiliary tests, ordered in accordance with suspected clinical conditions, should lead to accurate diagnosis. We highlight certain symptoms and clinical signs, ECG and X-ray findings, cardiac bio markers, arterial blood gases, and CT-scanning. Scores of severity and prognosis such as TIMI are assessed. Optimal treatment of the clinical conditions leading to chest pain depends on adequate initial approach and assessment.

  7. [Social pain]. (United States)

    Shimoyama, Naohito; Shimoyama, Megumi


    This chapter focuses on what social pain is and how it should be managed. In order to understand social pain in a cancer patient, it is necessary to recognize the change in the patient's daily life after the diagnosis of cancer. Because the degree of suffering and the relationships with family members and the people he or she worked with differ from patient to patient, it is important to note that the context of social pain is different in each patient. Five points shown below are essential in managing social pain. 1. Economical suffering may be alleviated by utilization of the social security system while taking into account each patient's standard of living. 2. Burdens on family members should be lessened, such as by not having them stay at the patient's bedside every day and letting them go home occasionally. 3. The normal patterns of communication, support, and conflict in the family should be identified, and the extent to which they have been disrupted by the illness should be assessed. 4. It is important to understand the ethnic, cultural, and religious background of the patient and the potential impact of their influence on the individual and the illness. 5. Practical or emotional unfinished business that the patient has needs to be identified, and efforts should be made to support fulfillment.

  10. Orofacial pain

    Directory of Open Access Journals (Sweden)

    Marjolijn Oomens


    Full Text Available In the primary care sector, diagnosis and initial management of orofacial pain are often performed by familydoctors and dentists. Knowledge of the different types of orofacial pain and headache disorders is therefor of great importance. The International Classification of Headache Disorders (ICHD-3 provides an overview of the different types of orofacial pain and will be discussed in this lecture. The main focus will be on trigeminal neuralgia and cluster headache and the current research in this field. Trigeminal Neuralgia (TN is defined as a disorder characterized by recurrent, unilateral, brief, electricshock-like pains, abrupt in onset and termination, limited to the distribution of one or more divisions of thetrigeminal nerve and triggered by innocuous stimuli. Unfortunately, most TN is idiopathic, and the aetiology isnot clear. The guidelines on pharmaceutical TN management published by the American Academy of Neurology (AAN and the European Federation of Neurological Societies (EFNS recommend carbamazepine (CBZ; 200–1200 mg/day or oxcarbazepine (OXC; 600–1800 mg/day as first-line therapy. Both are antiepileptics with well known interactions with other drugs and safety problems. An overview of the currently available literature on the pharmaceutical management of TN patients is discussed. Cluster headache (CH is one of the most painful primary headache disorders. It is characterized by daily or almost daily attacks of unilateral excruciating periorbital pain associated with ipsilateral cranial autonomic symptoms, typically lasting between 15 and 180 minutes if untreated. Cluster headache is caused by the relaesement of neurotransmitters and vasodilators from the sphenopalatine ganglion (SPH. The SPG is a large extracranial parasympathetic ganglion located in the pterygopalatine fossa (PPF. The current treatments for CH attacks are injectable sumatriptan and oxygen inhalation. Both treatments have well known side effects and

  11. Complementary and alternative medicine use by primary care patients with chronic pain. (United States)

    Rosenberg, Eric I; Genao, Inginia; Chen, Ian; Mechaber, Alex J; Wood, Jo Ann; Faselis, Charles J; Kurz, James; Menon, Madhu; O'Rorke, Jane; Panda, Mukta; Pasanen, Mark; Staton, Lisa; Calleson, Diane; Cykert, Sam


    To describe the characteristics and attitudes toward complementary and alternative medicine (CAM) use among primary care patients with chronic pain disorders and to determine if CAM use is associated with better pain control. Cross-sectional survey. Four hundred sixty-three patients suffering from chronic, nonmalignant pain receiving primary care at 12 U.S. academic medical centers. Self-reported current CAM usage by patients with chronic pain disorders. The survey had an 81% response rate. Fifty-two percent reported current use of CAM for relief of chronic pain. Of the patients that used CAM, 54% agreed that nontraditional remedies helped their pain and 14% indicated that their individual alternative remedy entirely relieved their pain. Vitamin and mineral supplements were the most frequently used CAM modalities. There was no association between reported use of CAM and pain severity, functional status, or perceived self-efficacy. Patients who reported having at least a high school education (odds ratio [OR] 1.1, 95% confidence interval [CI] 1.02-1.19, P = 0.016) and high levels of satisfaction with their health care (OR 1.47, 95% CI 1.13-1.91, P = 0.004) were significantly more likely to report using CAM. Complementary and alternative therapies were popular among patients with chronic pain disorders surveyed in academic primary care settings. When asked to choose between traditional therapies or CAM, most patients still preferred traditional therapies for pain relief. We found no association between reported CAM usage and pain severity, functional status, or self-efficacy.

  17. The impact of patient-reported outcome measures in clinical practice for pain: a systematic review. (United States)

    Holmes, Michelle M; Lewith, George; Newell, David; Field, Jonathan; Bishop, Felicity L


    Patient-reported outcome measures (PROMs) have increasingly been incorporated into clinical practice. Research suggests that PROMs could be viewed as active components of complex interventions and may affect the process and outcome of care. This systematic review examines PROMs in the context of treatment for non-malignant pain. An electronic search on: MEDLINE, EMBASE, PsycINFO, PsycARTICLES, Cochrane Library and Web of Science identified relevant papers (February 2015). The inclusion criteria were: focused on implementing PROMs into clinical practice, adults, and primary data studies. Critical interpretive synthesis was used to synthesise qualitative and quantitative findings into a theoretical argument. Thirteen eligible studies were identified. Synthesis suggested that PROMs may be included in the initial consultation to assess patients and for shared decision-making regarding patient care. During the course of treatment, PROMs can be used to track progress, evaluate treatment, and change the course of care; using PROMs may also influence the therapeutic relationship. Post-treatment, using PROMs might directly influence other outcomes such as pain and patient satisfaction. However, although studies have investigated these areas, evidence is weak and inconclusive. Due to the poor quality, lack of generalisability and heterogeneity of these studies, it is not possible to provide a comprehensive understanding of how PROMs may impact clinical treatment of non-malignant pain. The literature suggests that PROMs enable pain assessment, decision-making, the therapeutic relationship, evaluation of treatment and may influence outcomes. Further research is needed to provide better evidence as to whether PROMs do indeed have any effects on these domains.

  18. Pilot Randomized Trial Comparing Intersession Scheduling of Biofeedback Results to Individuals with Chronic Pain: Influence on Psychologic Function and Pain Intensity. (United States)

    Weeks, Douglas L; Whitney, Anthony A; Tindall, Angelique G; Carter, Gregory T


    The objective of this study was to compare the effectiveness of two biofeedback schedules on long-term improvement in physical and psychologic reactivity to chronic nonmalignant pain. This study is a prospective, randomized pilot trial. Twenty adults with chronic pain engaged in heart rate variability (HRV) biofeedback training for nine sessions with HRV presented visually. Two groups, formed by random assignment, were compared: The faded feedback group received concurrent visual HRV biofeedback in session 1, with the amount of biofeedback systematically reduced for ensuing sessions so that, by session 9, the participants were controlling HRV without external feedback. The full feedback group received visual HRV biofeedback continuously across all sessions. Outcome measures assessed at baseline, immediately after the program, and 3 mos after the program included pain intensity, fear-avoidance beliefs, and self-report physical functioning. Use of biofeedback skills was also assessed 3 mos after the program. Nominal variables were analyzed with χ. Continuous measures were analyzed with repeated-measures analyses of variance. The faded feedback schedule resulted in greater use of biofeedback skills at 3 mos and improved pain intensity and fear-avoidance beliefs after the program and at 3 mos. Physical functioning did not differ between groups. Systematically reducing the frequency of external visual feedback during HRV biofeedback training was associated with reduced reactivity to chronic pain. Results of this pilot study should be confirmed with a larger randomized study.

  19. Pain and the ethics of pain management. (United States)

    Edwards, R B


    In this article I clarify the concepts of 'pain', 'suffering', 'pains of body', 'pains of soul'. I explore the relevance of an ethic to the clinical setting which gives patients a strong prima facie right to freedom from unnecessary and unwanted pain and which places upon medical professionals two concomitant moral obligations to patients. First, there is the duty not to inflict pain and suffering beyond what is necessary for effective diagnosis, treatment and research. Next, there is the duty to do all that can be done to relieve all the pain and suffering which can be alleviated. I develop in some detail that individuality of pain sensitivity must be taken into account in fulfilling these obligations. I explore the issue of the relevance of informed consent and the right to refuse treatment to the matter of pain relief. And I raise the question of what conditions, if any, should override the right to refuse treatment where pain relief is of paramount concern.

  20. Positive Response to Thermobalancing Therapy Enabled by Therapeutic Device in Men with Non-Malignant Prostate Diseases: BPH and Chronic Prostatitis

    Directory of Open Access Journals (Sweden)

    Ivan Gerasimovich Aghajanyan


    Full Text Available Background: The most common types of non-malignant prostate diseases are benign prostatic hyperplasia (BPH and chronic prostatitis (CP. The aim of this study was to find out whether thermobalancing therapy with a physiotherapeutic device is effective for BPH and CP. Methods: During a 2.5-year period, 124 men with BPH over the age of 55 were investigated. Clinical parameters were tested twice: via the International Prostate Symptom Score (IPSS and via ultrasound measurement of prostate volume (PV and uroflowmetry maximum flow rate (Qmax, before and after six months of therapy. In 45 men with CP under the age of 55, the dynamics of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI were studied. Results: The results of the investigated index tests in men with BPH confirmed a decrease in IPSS (p < 0.001, a reduction in PV (p < 0.001, an increase in Qmax (p < 0.001, and an improvement of quality of life (QoL (p < 0.001. NIH-CPSI scores in men with CP indicated positive dynamics. Conclusions: The observed positive changes in IPSS, PV, and Qmax in men with BPH and the improvement in NIH-CPSI-QoL in patients with CP after using a physiotherapeutic device for six months as mono-therapy, support the view that thermobalancing therapy with the device can be recommended for these patients. Furthermore, the therapeutic device is free of side effects.

  2. Early CD3+/CD15+ peripheral blood leukocyte chimerism patterns correlate with long-term engraftment in non-malignant hematopoietic SCT. (United States)

    Ketterl, T G; Flesher, M; Shanley, R; Miller, W


    Following hematopoietic SCT (HSCT) for non-malignant disorders (NMDs) variable donor chimerism among lympho-hematopoietic lines may be observed. We retrospectively evaluated early post-HSCT, lineage-sorted (CD3+ and CD15+) peripheral blood leukocyte chimerism data to characterize patterns and assess for association with long-term CD15+ engraftment. 'Early' was defined as the first value obtained between days +14 and +42, 'late' as the last recorded value after day +90. 'High' donor chimerism was defined as 80% on either fraction at all time-points. Patients were classified into four subgroups with respect to early CD3+/CD15+ chimerism patterns (high/low) then analyzed for long-term CD15+ chimerism status. A total of 135 transplants were evaluable, with all three time-points available in 97. Underlying disease, graft source, patient age and conditioning intensity varied. 'Split' early chimerism (discordant high/low CD3+/CD15+ status) was common. Multivariable analysis revealed strong association between conditioning regimen and primary disease on early CD3+/CD15+ chimerism patterns and a dominant predictive effect of early CD15+ chimerism on long-term CD15+ donor engraftment (observed at median day +365). These data may guide real-time clinician decisions (restraint vs intervention, when available) when faced with unfavorable or unusual early lympho-hematopoietic chimerism patterns following HSCT for NMD.

  6. A controlled study of a serotonin reuptake blocker, zimelidine, in the treatment of chronic pain. (United States)

    Gourlay, G K; Cherry, D A; Cousins, M J; Love, B L; Graham, J R; McLachlan, M O


    Zimelidine inhibits the central neuronal reuptake of serotonin and has undergone clinical evaluation as an antidepressant. Twenty patients with chronic pain of non-malignant origin (mean duration 15.8 years) were entered into a double blind cross-over study of the analgesic efficacy of zimelidine and placebo. The duration of each treatment phase was 6 weeks and there was a comprehensive assessment of each patient prior to the commencement and at the completion of the study, during a brief period of hospitalisation. Zimelidine was superior (P less than 0.05) to placebo with respect to pain relief based on a global assessment (by the clinical investigators) performed at the completion of each treatment phase. However, there was no significant difference in analgesic efficacy between the zimelidine and placebo treatment phases based on the following criteria: (a) changes in the minimum effective blood concentration of pethidine necessary to provide pain relief in each patient, measured during a pethidine infusion of 1.67 mg/min for 60 min; (b) changes in pain scores estimated by patients using the visual analogue pain scale (VAPS); (c) changes in patients' estimates of pain intensity associated with various daily activities. Significant pain relief was apparent within 2-3 days in those patients who had a beneficial effect, which contrasts with the documented 3-4 weeks for maximal antidepressant effects. The results of this study suggest that serotonin reuptake blockers do not provide consistent pain relief in patients with chronic pain, but may contribute an analgesic effect in the treatment of some patients.

    Full Text Available This study extends prior research on vicarious traumatization and emotion management by exploring a deeper, more life-altering effect of working with traumatized clients—namely, “soul pain.” Analyses of in-depth interviews with 29 advocates working with survivors of physical and sexual violence reveal that, as a direct consequence of hearing countless stories of human brutality, some staff members experience a profound wounding of their spirit. This finding expands our understanding of the occupational hazards of the helping professions by revealing another dimension of advocates’ lives—that of the soul or spirit—that may be affected by their work with trauma survivors.

    Full Text Available Background: Gastrointestinal tract endoscopy along with biopsy is an established procedure for investigating a wide range of gastrointestinal conditions especially inflammatory and malignant diseases. The aim was to study and categorizing the morphological lesions of non-malignant origin at various sites of gastrointestinal tract and to compare with its endoscopic findings.Materials and Methods: This study was conducted on 280 benign GI biopsies received in the Department of Pathology of Sri Guru Ram Das Institute of Medical Sciences and Research, Amritsar, Punjab, India.Results: Maximum cases (39% were observed in the age group of 41-60 years. Male patients outnumbered the females (male to female ratio was 1.4:1. There were total 33 esophageal biopsies amongst which the most common lesion was non-specific esophagitis with least common being Barrett’s esophagus. Correlating the results of endoscopic and histopathological features of acute and chronic gastritis a positive predictive value of 80% with sensitivity of 44.4% was seen. Total 83 duodenal biopsies were analyzed with non-specific duodenitis being the most commonly diagnosed lesion followed by celiac disease. Correlation of endoscopic and histopathological findings in celiac disease revealed a sensitivity of 50% and positive predictive value of 42.86%. In both sigmoid colon and rectum, non-specific colitis was the commonest diagnosis followed by ulcerative colitis. Endoscopic findings were correlated with the histopathological features in ulcerative colitis, revealing a sensitivity of 57.14% along with the positive predictive value of 80%.  Conclusion: Histopathology remains the gold standard for diagnosing a case along with endoscopic findings and endoscopic findings alone cannot make the final diagnosis.

Results The objective of this study was to investigate the relationship between EBV genotypes (Zp variants and EBV type 1 and 2 and the clinical phenotypes of EBV-associated diseases in Chinese children. The Zp region was directly sequenced in 206 EBV-positive DNA samples from the blood of patients with IM, EBV-HLH, CAEBV, and healthy controls. Type 1 or type 2 EBV was examined by PCR for EBNA2 and EBNA3C subtypes. Four polymorphic Zp variants were identified: Zp-P, Zp-V3, Zp-P4 and Zp-V1, a new variant. The Zp-V3 variant was significantly associated with CAEBV (P ≤ 0.01. The frequency of co-infection with Zp variants was higher in patients with CAEBV and EBV-HLH, compared with IM and healthy controls, mostly as Zp-P+V3 co-infection. Type 1 EBV was predominant in all categories (81.3-95% and there was no significant difference in the frequency of the EBV types 1 and 2 in different categories (P > 0.05. Conclusions Type 1 EBV and BZLF1 Zp-P of EBV were the predominant genotypes in nonmalignant EBV associated diseases in Chinese children and Zp-V3 variant may correlates with the developing of severe EBV infection diseases, such as CAEBV and EBV-HLH.

    Anticipating case management is considered crucial in pediatric palliative care. In 2012, our children's university hospital initiated a specialized pediatric palliative care team (PPCT) to deliver inbound and outbound case management for children with life-shortening disease. The aim of this report is to gain insight in the first 9 months of this PPCT. Aspects of care during the first 9 months of the PPCT are presented, and comparison is made between patients with malignant disease (MD) and nonmalignant disease (NMD) in a retrospective study design. Insight in the aspects of care of all patients with a life-shortening disease was retrieved from web-based files and the hour registrations from the PPCT. Forty-three children were supported by the PPCT during the first 9 months: 22 with MD with a median of 50 (1-267) days and 29 minutes (4-615) of case management per patient per day and 21 patients with NMD with a median of 79.5 (5-211) days and 16 minutes of case management per day (6-64). Our data show significantly more interprofessional contacts for patients with MD and more in-hospital contacts for patients with NMD. The median number of admission days per patient was 11 (0-22) for MD (44% for anticancer therapy) and 44 (0-303) for NMD (36% for infectious diseases). This overview of aspects of pediatric palliative case management shows shorter but more intensive case management for MD in comparison with NMD. This insight in palliative case management guides the design of a PPCT.

  17. Expression of estrogen receptors in non-malignant mammary tissue modifies the association between insulin-like growth factor 1 and breast cancer risk. (United States)

    Samoli, E; Lagiou, A; Zourna, P; Barbouni, A; Georgila, C; Tsikkinis, A; Vassilarou, D; Minaki, P; Sfikas, C; Spanos, E; Trichopoulos, D; Lagiou, P


    Several studies have reported that the insulin-like growth factor 1 (IGF-1) is positively associated with estrogen receptor-positive [ER(+)] breast cancer risk, whereas there is little or no association with respect to ER(-) breast cancer. All comparisons of ER(+) breast cancer cases, however, have been made versus healthy controls, for whom there is no information about the ER expression in their mammary gland. In the context of a case-control investigation conducted in Athens, Greece, we studied 102 women with incident ERα(+) breast cancer and compared their IGF-1 blood levels with those of 178 ERα(+) and 83 ERα(-) women with benign breast disease (BBD) who underwent biopsies in the context of their standard medical care. Data were analysed using multiple logistic regression and controlling for potential confounding variables. ERα(+) breast cancer patients had higher IGF-1 levels compared with women with BBD [odds ratio (OR) 1.36, 95% confidence interval (CI): 0.95-1.94, per 1 standard deviation (SD) increase in IGF-1 levels]. When ERα status of women with BBD was taken into account, the difference in IGF-1 levels between ERα(+) breast cancer patients and women with BBD was clearly driven by the comparison with BBD women who were ERα(+) (OR = 1.95, 95% CI: 1.31-2.89 per 1 SD increase in IGF-1 levels), whereas there was essentially no association with IGF-1 levels when ERα(+) breast cancer patients were compared with ERα(-) BBD women. These contrasts were particularly evident among post/peri-menopausal women. We found evidence in support of an interaction of IGF-1 with the expression of ERα in the non-malignant mammary tissue in the context of breast cancer pathogenesis. This is in line with previous evidence suggesting that IGF-1 increases the risk of ER(+) breast cancer.

  18. Mortality from non-malignant respiratory diseases among people with silicosis in Hong Kong: exposure-response analyses for exposure to silica dust. (United States)

    Tse, L A; Yu, I T S; Leung, C C; Tam, W; Wong, T W


    To examine the exposure-response relationships between various indices of exposure to silica dust and the mortality from non-malignant respiratory diseases (NMRDs) or chronic obstructive pulmonary diseases (COPDs) among a cohort of workers with silicosis in Hong Kong. The concentrations of respirable silica dust were assigned to each industry and job task according to historical industrial hygiene measurements documented previously in Hong Kong. Exposure indices included cumulative dust exposure (CDE) and mean dust concentration (MDC). Penalised smoothing spline models were used as a preliminary step to detect outliers and guide further analyses. Multiple Cox's proportional hazard models were used to estimate the dust effects on the risk of mortality from NMRDs or COPDs after truncating the highest exposures. 371 of the 853 (43.49%) deaths occurring among 2789 workers with silicosis during 1981-99 were from NMRDs, and 101 (27.22%) NMRDs were COPDs. Multiple Cox's proportional hazard models showed that CDE (p = 0.009) and MDC (pcaisson workers and among those ever employed in other occupations with high exposure to silica dust. No exposure-response relationship was observed for surface construction workers with low exposures. A clear upward trend for both NMRDs and COPDs mortality was found with increasing severity of radiological silicosis. This study documented an exposure-response relationship between exposure to silica dust and the risk of death from NMRDs or COPDs among workers with silicosis, except for surface construction workers with low exposures. The risk of mortality from NMRDs increased significantly with the progression of International Labor Organization categories, independent of dust effects.

    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. © 2012 American Headache Society.

    Mechanisms of inflammatory and neuropathic pains have been elucidated and translated to patient care by the use of animal models of these pain states. Cancer pain has lagged behind since early animal models of cancer-induced bone pain were based on the systemic injection of carcinoma cells....... This precluded systematic investigation of specific neuronal and pharmacological alterations that occur in cancer-induced bone pain. In 1999, Schwei et al. described a murine model of cancer-induced bone pain that paralleled the clinical condition in terms of pain development and bone destruction, confined...... to the mouse femur. This model prompted related approaches and we can now state that cancer pain may include elements of inflammatory and neuropathic pains but also unique changes in sensory processing. Cancer induced bone pain results in progressive bone destruction, elevated osteoclast activity...

    Full Text Available Abstract Background Alexithymia is a disturbance associated with psychosomatic disorders, pain syndromes, and a variety of psychiatric disorders. The Affect School (AS based on Tomkins Affect Theory is a therapy focusing on innate affects and their physiological expressions, feelings, emotions and scripts. In this pilot study we tried the AS-intervention method in patients with chronic benign pain. Methods The AS-intervention, with 8 weekly group sessions and 10 individual sessions, was offered to 59 patients with chronic non-malignant pain at a pain rehabilitation clinic in Sweden 2004-2005. Pre and post intervention assessments were done with the Hospital Anxiety and Depression scale (HAD, the Toronto Alexithymia Scale-20 (TAS-20, the Visual Analogue Scale for pain assessment (VAS-pain, the European Quality of Life health barometer (EQoL and the Stress and Crisis Inventory-93 (SCI-93. After the group sessions we used Bergdahl's Questionnaire for assessing changes in interpersonal relations, general well-being and evaluation of AS.

  9. Pain in cancer survivors

    International Nuclear Information System (INIS)

    Mladosievicova, B.


    Pain is a common problem among cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain. Overall prevalence of all types pain is about 40% in some cancer survivors with previous specific diagnosis. Until recently, impact of pain in cancer survivors have largely been unexamined. This complication can be predicted by type of malignancy, its therapy, time elapsed from completion of anticancer treatment and effectivity of previous pain interventions. As the purpose of this article is to update readers on more recent data about prevalence of pain in cancer survivors and common treatment-related chronic pain etiologies in patients with a history of cancer who are beyond the acute diagnosis and treatment phase, previously known information about acute pain, pain in terminally ill patients. Some new studies in certain subpopulations of cancer survivors will be explored in more detail. (author)

    Senescence is a fundamental biological process implicated in various pathologies, including cancer. Regarding carcinogenesis, senescence signifies, at least in its initial phases, an anti-tumor response that needs to be circumvented for cancer to progress. Micro-RNAs, a subclass of regulatory, non-coding RNAs, participate in senescence regulation. At the subcellular level micro-RNAs, similar to proteins, have been shown to traffic between organelles influencing cellular behavior. The differential function of micro-RNAs relative to their subcellular localization and their role in senescence biology raises concurrent in situ analysis of coding and non-coding gene products in senescent cells as a necessity. However, technical challenges have rendered in situ co-detection unfeasible until now. In the present report we describe a methodology that bypasses these technical limitations achieving for the first time simultaneous detection of both a micro-RNA and a protein in the biological context of cellular senescence, utilizing the new commercially available SenTraGor TM compound. The method was applied in a prototypical human non-malignant epithelial model of oncogene-induced senescence that we generated for the purposes of the study. For the characterization of this novel system, we applied a wide range of cellular and molecular techniques, as well as high-throughput analysis of the transcriptome and micro-RNAs. This experimental setting has three advantages that are presented and discussed: i) it covers a "gap" in the molecular carcinogenesis field, as almost all corresponding in vitro models are fibroblast-based, even though the majority of neoplasms have epithelial origin, ii) it recapitulates the precancerous and cancerous phases of epithelial tumorigenesis within a short time frame under the light of natural selection and iii) it uses as an oncogenic signal, the replication licensing factor CDC6, implicated in both DNA replication and transcription when over

  12. Helicobacter pylori and nonmalignant diseases.

    LENUS (Irish Health Repository)

    Alakkari, Alaa


    Research published over the past year has documented the continued decline of Helicobacter pylori-related peptic ulcer disease and increased recognition of non-H. pylori, non-steroidal anti-inflammatory drugs ulcer disease--idiopathic ulcers. Despite reduced prevalence of uncomplicated PUD, rates of ulcer complications and associated mortality remain stubbornly high. The role of H. pylori in functional dyspepsia is unclear, with some authors considering H. pylori-associated nonulcer dyspepsia a distinct organic entity. There is increasing acceptance of an inverse relationship between H. pylori and gastroesophageal reflux disease (GERD), but little understanding of how GERD might be more common\\/severe in H. pylori-negative subjects. Research has focused on factors such as different H. pylori phenotypes, weight gain after H. pylori eradication, and effects on hormones such as ghrelin that control appetite.

  14. Loin pain hematuria syndrome. (United States)

    Taba Taba Vakili, Sahar; Alam, Tausif; Sollinger, Hans


    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.

  4. Pain in Down's Syndrome

    Directory of Open Access Journals (Sweden)

    Federica Mafrica


    Full Text Available Pain is a homeostatic mechanism that intervenes to protect the organism from harmful stimuli that could damage its integrity. It is made up of two components: the sensory-discriminative component, which identifies the provenance and characteristics of the type of pain; and the affective-motivational component, on which emotional reflexes, following the painful sensation, depend.There is a system for pain control at an encephalic and spinal level, principally made up of the periaqueductal grey matter, the periventricular area, the nucleus raphe magnus, and the pain-inhibition complex situated in the posterior horns of the spinal cord. Through the activation of these pain-control systems, the nervous system suppresses the afference of pain signals. Endogenous opioids represent another analgesic system.In the course of various studies on pain transmission in Down patients, the reduced tolerance of pain and the incapacity to give a qualitative and quantitative description emerged in a powerful way. All of these aspects cause difficulty in evaluating pain. This is linked to several learning difficulties. However, it cannot be excluded that in these anomalies of pain perception, both the anatomical and the neurotransmitter alteration, typical of this syndrome, may hold a certain importance.This fact may have important clinical repercussions that could affect the choice of therapeutic and rehabilitative schemes for treatment of pathologies in which pain is the dominant symptom, such as postoperative pain. It could influence research on analgesics that are more suitable for these patients, the evaluation of the depth of analgesia during surgical operation, and ultimately, absence of obvious pain manifestations. In conclusion, alterations of the central nervous system, neurotransmitters, pain transmission, and all related problems should be considered in the management of pain in patients with Down's syndrome, especially by algologists and

  8. The assessment and treatment of back and neck pain: an initial investigation in a primary care practice-based research network. (United States)

    Fischbein, Rebecca; McCormick, Kenelm; Selius, Brian A; Labuda Schrop, Susan; Hewit, Michael; Baughman, Kristin; Meeker, James


    The purpose of this study was to conduct an exploratory examination of the current state of non-malignant acute and chronic back and neck pain assessment and management among primary care providers in a multi-site, practice-based research network. Acute and chronic pain are distinct conditions that often require different assessment and management approaches, however, little research has examined assessment and management of acute and chronic pain as separate conditions. The large majority of patients with acute and chronic back and neck pain are managed in primary care settings. Given the differences between acute and chronic pain, it is necessary to identify differences in patient characteristics, practitioner evaluation, treatment and management in primary care settings. Over a two-week period, 24 practitioners in a multi-site practice-based research network completed 196 data cards about 39 patients experiencing acute back and neck pain and 157 patients suffering from chronic back and neck pain. Findings There were significant differences between the patients experiencing acute and chronic pain in regards to practitioner evaluation, current medication management and current treatment for depression. In addition, diagnostics differed between patients experiencing acute versus chronic back and neck pain. Further, primary care providers' review of online drug monitoring program reports during the current visit was associated with current medication management using short term opioids, long-term opioids or tramadol. Most research examining acute and chronic pain focuses on the low back. Additional research needs to be conducted to explore and compare acute and chronic pain across the whole spine.

  9. The influence of children's pain memories on subsequent pain experience. (United States)

    Noel, Melanie; Chambers, Christine T; McGrath, Patrick J; Klein, Raymond M; Stewart, Sherry H


    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. Children's pain perspectives. (United States)

    Esteve, R; Marquina-Aponte, V


    Previous studies on children's pain perspectives remain limited to English-speaking populations. An exploratory cross-sectional descriptive design was used to investigate the developmental progression of children's pain perspectives, including their pain experience, its definition and attributes, causality and coping. The Children's Pain Perspectives Inventory was applied to 180 healthy Spanish children. A coding system was developed following the content analysis method. Three age groups were compared: 4-6 years, corresponding to the Piagetian pre-operational stage of cognitive development; 7-11 years, corresponding to stage of concrete operations; and 12-14 years, corresponding to the period of early formal operations. In children between 4 and 6, the predominant narratives related to physical injuries, the notion of causality and the definition of pain. In children between 7 and 11, the predominant narratives were those in which pain was described as a sensation in one part of the body. The view of pain as having an emotional basis significantly increased with age and was more frequent in adolescents. In contrast, children between 4-6 and 7-11 indicated that pain occurs spontaneously. The denial of any positive aspects of pain significantly decreased with age; some children between 7 and 11 referred to the 'possibility of relief', while the view that pain is a 'learning experience' was significantly more frequent among adolescents aged between 12 and 14 years. The use of cognitive strategies to control pain significantly increased with age. Between 12 and 14 years of age, adolescents communicate pain by non-verbal behaviour and reported that they do not express demands for relief. There was a progression from concrete to more complex notions of pain as age increased. These results may be of use to health professionals and parents to understand how children at various developmental stages express and cope with pain and to develop tools that effectively assess and

  20. Pain-related worry in patients with chronic orofacial pain. (United States)

    Davis, C Ervin; Stockstill, John W; Stanley, William D; Wu, Qiang


    Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. The authors assessed people who had a diagnosis of chronic orofacial pain by using nonpain-related trait worry, state anxiety, trait anxiety, PC and pain measures. The participants' answers to an open-ended question about what they were most worried about led to the identification of worry domains, including worry about pain. The authors found that worrying about pain was related significantly to worst and least pain levels, pain interference and pain duration, as well as moderated trait worry in predicting pain interference. Although trait worry was not correlated directly with pain, when moderated by PC, it made substantial contributions in predicting pain interference. Participants with chronic orofacial pain reported experiencing substantial levels of trait worry, anxiety, PC and worry about pain that related to pain ratings directly and indirectly. Clinicians should assess pain-related worry in patients with chronic orofacial pain to understand the effects of worry on pain and functioning. Clinicians could treat these patients more effectively by helping them reduce their levels of pain-related worry and focusing on improved coping.

  1. Dancing in pain: pain appraisal and coping in dancers. (United States)

    Anderson, Ruth; Hanrahan, Stephanie J


    This study investigated the relationships between the type of pain experienced (performance pain and injury pain), the cognitive appraisal of pain and pain coping styles in dancers. 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.

  5. Nutraceuticals and osteoarthritis pain. (United States)

    Wang, Angela; Leong, Daniel J; Cardoso, Luis; Sun, Hui B


    Arthritis is a chronic disease of joints. It is highly prevalent, particularly in the elderly, and is commonly associated with pain that interferes with quality of life. Because of its chronic nature, pharmacological approaches to pain relief and joint repair must be safe for long term use, a quality many current therapies lack. Nutraceuticals refer to compounds or materials that can function as nutrition and exert a potential therapeutic effect, including the relief of pain, such as pain related to arthritis, of which osteoarthritis (OA) is the most common form. Of interest, nutraceuticals have recently been shown to have potential in relieving OA pain in human clinical trials. Emerging evidence indicates nutraceuticals may represent promising alternatives for the relief of OA pain. In this paper, we will overview OA pain and the use of nutraceuticals in OA pain management, focusing on those that have been evaluated by clinical trials. Furthermore, we discuss the biologic and pharmacologic actions underlying the nutraceutical effects on pain relief based on the potential active ingredients identified from traditional nutraceuticals in OA pain management and their potential for drug development. The review concludes by sharing our viewpoints that future studies should prioritize elucidating the mechanisms of action of nutraceuticals in OA and developing nutraceuticals that not only relieve OA pain, but also mitigate OA pathology.

  6. Fantom pain: Case report

    Directory of Open Access Journals (Sweden)

    Marić Sanja S.


    Full Text Available Background Phantom limb pain is a common problem after limb amputation (41-85%. It is described as an extremely painful sensation in the missing part of the body that can last for hours, days or even years. It is considered to arise from cortical reorganization, although many factors can increase the risk of phantom limb pain: pain before surgery, age and sex of the patients, the time elapsed since surgery, stump pain, inadequate prosthesis. Phantom limb pain therapy is very complicated. Case report We reported a case of 80-year-old patient suffering from phantom limb pain and phantom sensation 25 years after the amputation of his left leg due to the injury. The patient has pain at the site of amputation, sensation that he has the leg and that it occupies an unusual position and almost daily exhausting phantom limb pain (6-9 visual analogue scale - VAS with disturbed sleep and mood. We managed to reduce the pain under 4 VAS and decrease the patient suffering by combining drugs from the group of coanalgetics (antidepressants, antiepileptics, non-pharmacological methods (transcutaneous electroneurostimulation - TENS, mirror therapy and femoral nerve block in the place of disarticulation of the left thigh. Conclusion Phantom limb pain therapy is multimodal, exhausting for both the patient and the physician and it is often unsuccessful. The combination of different pharmacological and non-pharmacological modalities can give satisfactory therapeutic response.

  7. Ketamine for pain (United States)

    Jonkman, Kelly; Dahan, Albert; van de Donk, Tine; Aarts, Leon; Niesters, Marieke; van Velzen, Monique


    The efficacy of the N-methyl-D-aspartate receptor antagonist ketamine as an analgesic agent is still under debate, especially for indications such as chronic pain. To understand the efficacy of ketamine for relief of pain, we performed a literature search for relevant narrative and systematic reviews and meta-analyses. We retrieved 189 unique articles, of which 29 were deemed appropriate for use in this review. Ketamine treatment is most effective for relief of postoperative pain, causing reduced opioid consumption. In contrast, for most other indications (that is, acute pain in the emergency department, prevention of persistent postoperative pain, cancer pain, and chronic non-cancer pain), the efficacy of ketamine is limited. Ketamine’s lack of analgesic effect was associated with an increase in side effects, including schizotypical effects. PMID:28979762

  8. The Pain of Labour (United States)

    Labor, Simona


    Labour is an emotional experience and involves both physiological and psychological mechanisms. The pain of labour is severe but despite this its memory diminishes with time. Labour pain has two components: visceral pain which occurs during the early first stage and the second stage of childbirth, and somatic pain which occurs during the late first stage and the second stage. The pain of labour in the first stage is mediated by T10 to L1 spinal segments, whereas that in the second stage is carried by T12 to L1, and S2 to S4 spinal segments. Pain relief in labour is complex and often challenging without regional analgesia. Effective management of labour pain plays a relatively minor role in a woman's satisfaction with childbirth.

  9. Pain emotion and homeostasis. (United States)

    Panerai, Alberto E


    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.

  10. Back Pain in Children

    Directory of Open Access Journals (Sweden)

    Sadi Kayiran ; Sinan Mahir Kayiran;


    Full Text Available Contrary to popular knowledge, back pain is quite frequently seen in children. While very rare in the pre-school age group, frequency reaches 30% in the adolescent period. In many cases, the causes of back pain in childhood cannot be exactly determined and the pain disappears by itself in a short time. It should be remembered that back pain that persists for more than two weeks may be associated with organic causes. Whether or not there have been disruptions in neurological functions should be definitely probed in the medical history. Keeping in mind that back pain could be a part of a systemic disease, a systemic examination should be carried out in cases where there has been long-term back pain. The complaint of childhood back pain should be assessed with a thorough history, a careful physical examination and advanced testing tools. [TAF Prev Med Bull 2011; 10(1.000: 115-118

    Full Text Available 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.

    In patients with back pain there is only a poor correlation between clinical and radiological symptoms. Therefore the interpretation of radiological findings is only possible with respect to the natural history of the disease. Indication for radiological examination is given for early diagnosis and treatment of malinformation of the spine; diagnosis and treatment of functional disturbances of the spine with back- and low back pain and diagnosis and treatment of diseases which affect the stability of the vertebrae.

  13. Maintenance of Pain in Children With Functional Abdominal Pain. (United States)

    Czyzewski, Danita I; Self, Mariella M; Williams, Amy E; Weidler, Erica M; Blatz, Allison M; Shulman, Robert J


    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 3 methods for assessing pain-stooling relations (ie, diary, parent report, child report). Seventy-six children (7-10 years old at baseline) who presented for medical treatment of functional abdominal pain were followed up 18 to 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. Children's baseline anxiety was not related to persistence of pain frequency. Children who, however, 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. The presence of IBS symptoms in school-age children with functional abdominal pain appears to predict persistence of abdominal pain over time, whereas 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.

  14. Pain after earthquake

    Full Text Available Abstract 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.

  15. Chronic Abdominal Wall Pain. (United States)

    Koop, Herbert; Koprdova, Simona; Schürmann, Christine


    Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

  18. Spiritual pain and suffering. (United States)

    Brunjes, George B


    Spiritual pain/suffering is commonly experienced by persons with life-limiting illness and their families. Physical pain itself can be exacerbated by non-physical causes such as fear, anxiety, grief, unresolved guilt, depression and unmet spiritual meets. Likewise, the inability to manage physical pain well can be due to emotional and spiritual needs. This is why a holistic, interdisciplinary assessment of pain and suffering is required for each patient and family. The mind, body and spirit are understood in relationship to each other and, in those cases, in relationship to a deity or deities are important to understand. Cultural interpretations of pain and suffering may conflict with the goals of palliative care. Understanding the spiritual framework of the patient and family can help to assure that the physical and spiritual suffering of the patient can be eliminated to provide a peaceful death. Spiritual practices may help in the management of physical pain.

  19. [Cannabinoids in pain medicine]. (United States)

    Karst, M


    The endocannabinoid system (ECS) controls a large number of vital functions. Suboptimal tone of the ECS in certain regions of the nervous system may be associated with disorders that are also associated with pain. Pain and inflammation processes can be modulated by the exogenous supply of cannabinoids. Low-to-moderate pain-relieving effects and in individual cases large pain-relieving effects were observed in randomized, controlled studies of various types of chronic pain. People with chronic neuropathic pain and stress symptoms seem to particularly benefit. The therapeutic range of cannabinoids is small; often small doses are sufficient for clinically significant effects. The "Cannabis-als-Medizin-Gesetz" (cannabis as medicine law) allows the prescription of cannabis preparations under certain conditions. Available data indicate good long-term efficacy and tolerability. However, there is little systematic long-term experience from clinical studies.

    Full Text Available Background. Chronic unexplained orofacial pain is frequently the cause of prolonged suffering for the patient and an unsolvable problem for the therapist. Pathophysiology of the onset of this type of pain is virtually unknown. Still, it is possible to divide chronic orofacial pain into several separate categories, according to its onset, symptoms and therapy. All forms of this type of pain have a strong psychological component.Methods. A retrograde review was conducted, in which patients’ records, treated in 1994 for chronic unexplained orofacial pain, were followed through a 5 year period. The modalities of treatment then and at present were compared.Conclusions. Except for trigeminal neuralgia, where carbamazepine remains the first choice drug, treatment of chronic facial pain has changed considerably.

    Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

    Tarun Bhalla


    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Scoliosis is defined as a lateral deviation of the spine from the normal plumb line. Commonly, there is a rotational component and deviation also in the sagittal plane (kyphosis or hyperlordosis). When scoliosis presents in adults, it is often painful. In contrast, back pain in a child is considered rare, and serious underlying pathology should be excluded, particularly since idiopathic scoliosis is typically painless. A painful scoliosis in a child or adolescent, especially if the patient has a left-sided curve, should be examined thoroughly. The aim of this review is to illustrate the causes of a painful scoliosis in children, adolescents and adults. (orig.)

    The International Association for the Study of Pain defines pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage” (IASP, 1997). This definition of pain emphasises that it is neither a sensory nor an emotional experience, but a combination of both. It is a subjective experience influenced by physical, psychological and environmental factors that is assessed from a biopsychosocial perspective. The gold standard in assessing pain however is always what the patient says it is.

  10. Doubling Your Payoff: Winning Pain Relief Engages Endogenous Pain Inhibition (United States)

    Becker, Susanne; Gandhi, Wiebke; Kwan, Saskia; Ahmed, Alysha-Karima; Schweinhardt, Petra


    When in pain, pain relief is much sought after, particularly for individuals with chronic pain. In analogy to augmentation of the hedonic experience ("liking") of a reward by the motivation to obtain a reward ("wanting"), the seeking of pain relief in a motivated state might increase the experience of pain relief when obtained. We tested this hypothesis in a psychophysical experiment in healthy human subjects, by assessing potential pain-inhibitory effects of pain relief "won" in a wheel of fortune game compared with pain relief without winning, exploiting the fact that the mere chance of winning induces a motivated state. The results show pain-inhibitory effects of pain relief obtained by winning in behaviorally assessed pain perception and ratings of pain intensity. Further, the higher participants scored on the personality trait novelty seeking, the more pain inhibition was induced. These results provide evidence that pain relief, when obtained in a motivated state, engages endogenous pain-inhibitory systems beyond the pain reduction that underlies the relief in the first place. Consequently, such pain relief might be used to improve behavioral pain therapy, inducing a positive, perhaps self-amplifying feedback loop of reduced pain and improved functionality.

  11. Review of extended-release formulations of Tramadol for the management of chronic non-cancer pain: focus on marketed formulations (United States)

    Kizilbash, Arshi; Ngô-Minh, Cường


    Patients with chronic non-malignant pain report impairments of physical, social, and psychological well-being. The goal of pain management should include reducing pain and improving quality of life. Patients with chronic pain require medications that are able to provide adequate pain relief, have minimum dosing intervals to maintain efficacy, and avoid breakthrough pain. Tramadol has proven efficacy and a favourable safety profile. The positive efficacy and safety profile has been demonstrated historically in numerous published clinical studies as well as from post-marketing experience. It is a World Health Organization “Step 2” opioid analgesic that has been shown to be effective, well-tolerated, and valuable, where treatment with strong opioids is not required. A number of extended release formulations of Tramadol are available in Canada and the United States. An optimal extended release Tramadol formulation would be expected to provide consistent pain control with once daily dosing, few sleep interruptions, flexible dosing schedules, and no limitation on taking with meals. Appropriate treatment options should be based on the above proposed attributes. A comparative review of available extended release Tramadol formulations shows that these medications are not equivalent in their pharmacokinetic profile and this may have implications for selecting the optimal therapy for patients with pain syndromes where Tramadol is an appropriate analgesic agent. Differences in pharmacokinetics amongst the formulations may also translate into varied clinical responses in patients. Selection of the appropriate formulation by the health care provider should therefore be based on the patient’s chronic pain condition, needs, and lifestyle. PMID:24711710

  12. Cancer and orofacial pain. (United States)

    Romero-Reyes, M; Salvemini, D


    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 San Sebastioan-Donostia, Spain. 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. 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. 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.

  14. [Statins and muscle pain]. (United States)

    Yosef, Yoni; Schurr, Daniel; Constantini, Naama


    Statins are used for the prevention and treatment of cardiovascular disease. The treatment is quite safe but not free of side effects, particularly muscle pain. Fear of pain may prevent patients from carrying out exercise or diminish their motivation to return and engage in it, even though both the statins and the exercise have a proven benefit in both treatment and prevention, and a synergistic effect enhances this benefit. Prevalence of muscular pain ranges from 1-30%. Pain usually appears at the beginning of treatment, but can occur even after months and under any of the existing agents. The creatine phosphokinase (CPK) enzyme level may rise, but not necessarily. Increases to exceptional values (10 times the upper normal level) are relatively rare and rhabdomyolysis is extremely rare. The risk increases with age, co-morbidities and especially when taken concurrently with drugs that are metabolized in a similar pathway. Pain usually passes within a month after discontinuing treatment, but may persist for six months or more. Studies have examined the effect of statin therapy on the ability to perform physical activity, but results are inconsistent. The increased rise of CPK was observed under statin therapy, a tendency that increased with age. However, it was not accompanied by an increased incidence of muscle pain or rhabdomyolysis. Considering the above we recommend encouraging patients to exercise. However, patients should be instructed to report new or worsening muscular pains. Discontinuation, lowering dose or replacement should be considered when pain is suspected to be related with treatment.

  3. Altered Pain Sensitivity in Elderly Women with Chronic Neck Pain (United States)

    Uthaikhup, Sureeporn; Prasert, Romchat; Paungmali, Aatit; Boontha, Kritsana


    Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

  6. Pain and neuroplasticity

    Directory of Open Access Journals (Sweden)

    Sabine Sator-Katzenschlager, MD.


    However, the cerebral processing of hyperalgesia and allodynia is still controversially discussed. In recent years, neuroimaging methods (functional magnetic resonance imaging, fMRI; magnetoencephalography, MEG; positron emission tomography, PET have provided new insightsinto the aberrant cerebral processing of neuropathic pain. Thepresent paper reviews different cerebral mechanisms contributing to chronicity processes in neuropathic pain syndromes. These mechanisms include reorganisation of cortical somatotopic maps in sensory or motor areas (highly relevant for phantom limb pain and CRPS, increased activity in primary nociceptive areas, recruitment of new cortical areas usually not activated by nociceptive stimuli and aberrant activity in brain areas normally involved in descending inhibitory pain networks. Moreover, there is evidence from PET studies for changes of excitatory and inhibitory transmitter systems. Finally, advanced methods of structural brain imaging (voxel-based morphometry, VBM show significant structural changes suggesting that chronic pain syndromes may be associated with neurodegeneration.

  7. Child with Abdominal Pain. (United States)

    Iyer, Rajalakshmi; Nallasamy, Karthi


    Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies.

  9. Methadone for Cancer Pain

    Directory of Open Access Journals (Sweden)

    Eric E. Prommer


    Full Text Available Pain is one of the most common and incapacitating symptoms experienced by patients with advanced cancer. Methadone is a potent opioid with strong affinity for the µ opioid receptor. In addition to being a potent µ opioid receptor ligand, methadone blocks the N-methyl-D-aspartic acid receptor and modulates neurotransmitters involved in descending pain modulation. These 3 properties enhance analgesic activity. Methadone’s lack of active metabolites makes it an attractive option when opioid responsiveness declines and renal insufficiency complicates opioid therapy. A lipophilic opioid, methadone can be given by multiple routes. Clinical trial data show equivalence with morphine as an analgesic in moderate to severe cancer pain. Further investigations are needed to define the role of methadone in the management of breakthrough pain and neuropathic pain and to determine whether it is truly superior to morphine, the gold standard of cancer analgesia.

  10. Victimization and pain

    Directory of Open Access Journals (Sweden)

    Małgorzata K. Szerla


    Full Text Available Pain has several causes. It can be caused not only by operative trauma or cancer. Some patients suffer from pain as a result of being victims of violence. The aim of the study was to introduce diagnosis and treatment of pain problems in patients who are victims of violence, from a physician’s and a psychologist’s common perspective. Physical pain-related primary effects experienced by the victims of domestic violence go far beyond the results which are noticeable directly and confirmed visually in a forensic examination. In the present paper we introduce an ‘invisible’ group of secondary effects of violence. They appear in time, often after several years, in the form of a variety of psychosomatic disorders. The body is devastated insidiously and the secondary effects are visible as vegetative symptoms, a variety of psychosomatic disorders and pain, difficult to diagnose and treat.

  12. Pharmacogenomics and Patient Treatment Parameters to Opioid Treatment in Chronic Pain: A Focus on Morphine, Oxycodone, Tramadol, and Fentanyl. (United States)

    Lloyd, Renae A; Hotham, Elizabeth; Hall, Catherine; Williams, Marie; Suppiah, Vijayaprakash


    Opioids are one of the most commonly prescribed medicines for chronic pain. However, their use for chronic pain has been controversial. The objective of this literature review was to identify the role of genetic polymorphisms on patient treatment parameters (opioid dose requirements, response, and adverse effects) for opioids used in malignant and nonmalignant chronic pain. The opioids that this review focuses on are codeine, morphine, oxycodone, tramadol, and fentanyl. A literature search of databases Medline and Embase was carried out, and studies up to April 2016 were included in this review. Studies were included based on a combination of key words: chronic pain and related terms, pharmacogenetics and related terms, and opioids and related terms. Among the 1,408 individual papers retrieved from the search in Medline and Embase, 32 original articles were included in this review, with none related to codeine. The 32 papers reported various study designs, opioids, and polymorphisms being studied for associations with treatment outcomes. This literature review reveals that variants in ABCB1, OPRM1, and COMT have been replicated for opioid dosing and variants in ABCB1 have been replicated for both treatment response and adverse effects. Currently, there are few validated studies to form a strong evidence base to support pharmacogenomics testing when initiating opioid therapy. However, the field of pharmacogenomics in chronic pain is likely to expand over the coming years, with the increasing number of treatment options available and larger cohorts being assembled in order to identify true associations. © 2017 American Academy of Pain Medicine.

    Fabianna Resende de Jesus-Moraleida

    Full Text Available Abstract Introduction: Chronic neck pain is associated with significant health costs and loss of productivity at work. Objective: to assess pain and disability in individuals with chronic neck pain. Methods: 31 volunteers with chronic neck pain, mean age 29, 65 years, were assessed using the McGill Pain Questionnaire in Brazilian version (Br-MPQ and Neck Disability Index (NDI. The Br-MPQ analysis was performed based on the numerical values associated with the words selected to describe the experience of pain (Pain Rating Index - PRI, and present pain intensity (PPI. NDI was used to evaluate the influence of neck pain in performance of everyday tasks. Finally, we investigated the association between PPI and NDI. Results: PRI revealed that the most significant dimension was the sensory pain (70%, and the number of chosen words was 10 (2,62 out of 20 words. Mean PPI value was 1,23 (0,76 in five points; 40% of participants described pain intensity as moderate. NDI score was 9,77 (3,34, indicating mild disability. There was a positive association between disability and pain intensity (r = 0,36; p =0,046. Pain intensity and duration of pain were not associated. Conclusions: Findings of this study identified important information related to neck pain experienced by patients when suffering from chronic neck pain, moreover, the association between disability and pain intensity reinforces the importance of complementary investigation of these aspects to optimize function in them.

  14. Opioid prescriptions for pain and epidemic of overdose death: can the dramatic reduction in anesthesia mortality serve as an example?

    Directory of Open Access Journals (Sweden)

    Kissin I


    Full Text Available Igor Kissin Department of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston, MA, USA Abstract: The annual number of US deaths from prescription-opioid overdose quadrupled between 1999 and 2010 and in 2010 alone reached 16,651. Deaths from opioid overdose have now surpassed the historic death toll from another drug-related epidemic – anesthesia mortality. In 1954, Beecher and Todd published reliable data on anesthesia-related mortality in the US, estimating the annual number of deaths to be nearly 5,000. Presently anesthesia/anesthetics are reported as the underlying cause in approximately 34 deaths in the US annually. This spectacular decline in anesthesia-related mortality could serve as an example for attempts to curb the epidemic of opioid overdose death. The main reason that led to the dramatic decline in anesthesia-related mortality is the context in which anesthetics are used. It includes training of the anesthesia providers, the introduction of specific standards of patient safety, and anesthesia monitoring. I suggest that the introduction of a similar multifactorial proper context for the use of opioids in the treatment of chronic nonmalignant pain might be the same “game changer” it was for safety in anesthesia. Keywords: chronic pain, addiction, opioid-use disorder, treatment compliance, apprenticeship, metrics of opioid effectiveness, aberrant opioid-related behavior

  15. The painful shoulder

    International Nuclear Information System (INIS)

    Hartl, P.W.


    The painful shoulder syndrome is very common. Diagnosis and differential diagnosis may be difficult. Shoulder pain may be caused by local processes or systemic diseases or can be referred. Periarthritis humeroscapularis (frozen shoulder) is the most common cause of painful shoulder syndrome. Biomechanical factors concerning the rotator cuff are involved in the etiopathogenesis of these pain syndromes. The therapy of frozen shoulder includes physical treatment, antirheumatic drugs, or X-ray treatment. Surgical measures may become necessary. In the course of rheumatoid arthritis the shoulder may be involved. Milwaukee-shoulder-syndrome has been described recently in crystal deposit diseases. Shoulder pain may be referred by mechanical irritations of nerve roots in the course of degenerative lesions of the cervical spine and also in the course of internal diseases of the heart, the lungs, or the gastrointestinal tract. In cases of shoulder pain without pathological data from arthrological, radiological or laboratory studies, one should always consider localized fibromyalgia in the shoulder-neck-region. The precise diagnosis of shoulder pain is an important prerequisite for treatment, the success of which should not be judged as pessimistic as it has been commonly done in the past. (orig.) [de

  16. Efficient conditioned pain modulation despite pain persistence in painful diabetic neuropathy

    Directory of Open Access Journals (Sweden)

    Yelena Granovsky


    Conclusion:. Pro-nociception, expressed by less efficient CPM and high temporal summation that usually accompanies clinical painful conditions, seems to “normalize” with chronicity of the pain syndrome. This is despite continuing pain, suggesting that pro-nociceptivity in pain syndromes is multifactorial. Because the pain modulation profile affects success of therapy, this suggests that different drugs might express different efficacy pending on duration of the pain in patients with PDN.

  17. Language and the pain experience. (United States)

    Wilson, Dianne; Williams, Marie; Butler, David


    People in persistent pain have been reported to pay increased attention to specific words or descriptors of pain. The amount of attention paid to pain or cues for pain (such as pain descriptors), has been shown to be a major factor in the modulation of persistent pain. This relationship suggests the possibility that language may have a role both in understanding and managing the persistent pain experience. The aim of this paper is to describe current models of neuromatrices for pain and language, consider the role of attention in persistent pain states and highlight discrepancies, in previous studies based on the McGill Pain Questionnaire (MPQ), of the role of attention on pain descriptors. The existence of a pain neuromatrix originally proposed by Melzack (1990) has been supported by emerging technologies. Similar technologies have recently allowed identification of multiple areas of involvement for the processing of auditory input and the construction of language. As with the construction of pain, this neuromatrix for speech and language may intersect with neural systems for broader cognitive functions such as attention, memory and emotion. A systematic search was undertaken to identify experimental or review studies, which specifically investigated the role of attention on pain descriptors (as cues for pain) in persistent pain patients. A total of 99 articles were retrieved from six databases, with 66 articles meeting the inclusion criteria. After duplicated articles were eliminated, the remaining 41 articles were reviewed in order to support a link between persistent pain, pain descriptors and attention. This review revealed a diverse range of specific pain descriptors, the majority of which were derived from the MPQ. Increased attention to pain descriptors was consistently reported to be associated with emotional state as well as being a significant factor in maintaining persistent pain. However, attempts to investigate the attentional bias of specific 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.

    Full Text Available Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness.

  3. Conditioned pain modulation in patients with nonspecific chronic back pain with chronic local pain, chronic widespread pain, and fibromyalgia. (United States)

    Gerhardt, Andreas; Eich, Wolfgang; Treede, Rolf-Detlef; Tesarz, Jonas


    Findings considering conditioned pain modulation (CPM) in chronic back pain (CBP) are contradictory. This might be because many patients with CBP report pain in further areas of the body, and altered CPM might influence spatial extent of pain rather than CBP per se. Therefore, we compared CPM in patients with CBP with different pain extent. Patients with fibromyalgia syndrome (FMS), for whom CPM impairment is reported most consistently, were measured for comparison. Based on clinical evaluation and pain drawings, patients were categorized into chronic local back pain (CLP; n = 53), chronic widespread back pain (CWP; n = 32), and FMS (n = 92). Conditioned pain modulation was measured by the difference in pressure pain threshold (test stimuli) at the lower back before and after tonic heat pain (conditioning stimulus). We also measured psychosocial variables. Pressure pain threshold was significantly increased in CLP patients after tonic heat pain (P pain modulation in CLP was significantly higher than that in CWP and FMS (P painful areas (0-10) were associated with lower CPM (r = 0.346, P = 0.001) in CBP but not in FMS (r = -0.013, P = 0.903). Anxiety and depression were more pronounced in FMS than in CLP or CWP (P values pain inhibition seem to be more indicated the higher the pain extent.

  4. The efficacy of manual therapy and exercise for treating non-specific neck pain: A systematic review. (United States)

    Hidalgo, Benjamin; Hall, Toby; Bossert, Jean; Dugeny, Axel; Cagnie, Barbara; Pitance, Laurent


    To review and update the evidence for different forms of manual therapy (MT) and exercise for patients with different stages of non-specific neck pain (NP). MEDLINE, Cochrane-Register-of-Controlled-Trials, PEDro, EMBASE. A qualitative systematic review covering a period from January 2000 to December 2015 was conducted according to updated-guidelines. Specific inclusion criteria only on RCTs were used; including differentiation according to stages of NP (acute - subacute [ASNP] or chronic [CNP]), as well as sub-classification based on type of MT interventions: MT1 (HVLA manipulation); MT2 (mobilization and/or soft-tissue-techniques); MT3 (MT1 + MT2); and MT4 (Mobilization-with-Movement). In each sub-category, MT could be combined or not with exercise and/or usual medical care. Initially 121 studies were identified for potential inclusion. Based on qualitative and quantitative evaluation criteria, 23 RCTs were identified for review. Evidence for ASNP: MODERATE-evidence: In favour of (i) MT1 to the cervical spine (Cx) combined with exercises when compared to MT1 to the thoracic spine (Tx) combined with exercises; (ii) MT3 to the Cx and Tx combined with exercise compared to MT2 to the Cx with exercise or compared to usual medical care for pain and satisfaction with care from short to long-term. Evidence for CNP: STRONG-evidence: Of no difference of efficacy between MT2 at the symptomatic Cx level(s) in comparison to MT2 on asymptomatic Cx level(s) for pain and function. MODERATE to STRONG-evidence: In favour of MT1 and MT3 on Cx and Tx with exercise in comparison to exercise or MT alone for pain, function, satisfaction with care and general-health from short to moderate-terms. MODERATE-evidence: In favour (i) of MT1 as compared to MT2 and MT4, all applied to the Cx, for neck mobility, and pain in the very short term; (ii) of MT2 using sof-tissue-techniques to the Cx and Tx or MT3 to the Cx and Tx in comparison to no-treatment in the short-term for pain and disability

  6. Predicting postoperative pain by preoperative pressure pain assessment. (United States)

    Hsu, Yung-Wei; Somma, Jacques; Hung, Yu-Chun; Tsai, Pei-Shan; Yang, Chen-Hsien; Chen, Chien-Chuan


    The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive of postoperative surgical pain. Female subjects undergoing lower abdominal gynecologic surgery were studied. A pressure algometer was used preoperatively to determine the pressure pain threshold and tolerance. A visual analog scale (VAS) was used to assess postoperative pain. A State-Trait Anxiety Inventory was used to assess patients' anxiety. Subjects received intravenous patient-controlled analgesia for postoperative pain control. The preoperative pain threshold and tolerance were compared with the postoperative VAS pain score and morphine consumption. Forty women were enrolled. Their preoperative pressure pain threshold and tolerance were 141 +/- 65 kPa and 223 +/- 62 kPa, respectively. The VAS pain score in the postanesthesia care unit and at 24 h postoperatively were 81 +/- 24 and 31 +/- 10, respectively. Highly anxious patients had higher VAS pain scores in the postanesthesia care unit (P pain tolerance was significantly correlated with the VAS at 24 h postoperatively (P pain tolerance after fentanyl administration (mean, 272 +/- 68 kPa) correlated significantly with morphine consumption in the first 24 h postoperatively (P pain tolerance is significantly correlated with the level of postoperative pain. Pain tolerance assessment after fentanyl was administered and fentanyl sensitivity predicted the dose of analgesics used in the first 24 h after surgery. The algometer is thus a simple, useful tool for predicting postoperative pain and analgesic consumption.

  7. Postamputation pain: studies on mechanisms. (United States)

    Nikolajsen, Lone


    Amputation is followed by both painful and non-painful phantom phenomena in a large number of amputees. Non-painful phantom sensations rarely pose any clinical problem, but 60-80% of all amputees also experience painful sensations (i.e. phantom pain) located to the missing limb. The severity of phantom pain usually decreases with time, but severe pain persists in 5-10% of patients. Pain in the residual limb (i.e. stump pain) is another consequence of amputation. Both stump and phantom pain can be very difficult to treat. Treatment guidelines used for other neuropathic pain conditions are probably the best approximation, especially for the treatment of stump pain. The aim of the present doctoral thesis was to explore some of the mechanisms underlying pain after amputation. Ten studies were carried out (I-X). My PhD thesis from 1998 dealt with pain before the amputation and showed that preamputation pain increases the risk of phantom pain after amputation (I). A perioperative epidural blockade, however, did not reduce the incidence of pain or abnormal sensory phenomena after amputation (II, III). The importance of sensitization before amputation for the subsequent development of pain is supported by study IV, in which pressure pain thresholds obtained at the limb before amputation were inversely related to stump and phantom pain after 1 week. Afferent input from the periphery is likely to contribute to postamputation pain as sodium channels were upregulated in human neuromas (VI), although neuroma removal did not always alleviate phantom pain (V). Sensitization of neurons in the spinal cord also seems to be involved in pain after amputation as phantom pain was reduced by ketamine, an NMDA-receptor antagonist. Another NMDA-receptor antagonist, memantine, and gabapentin, a drug working by binding to the δ2α-subunit of voltage-gated calcium channels, had no effect on phantom pain (VII-IX). Supraspinal factors are also important for pain after amputation as

  14. Functional abdominal pain syndrome. (United States)

    Clouse, Ray E; Mayer, Emeran A; Aziz, Qasim; Drossman, Douglas A; Dumitrascu, Dan L; Mönnikes, Hubert; Naliboff, Bruce D


    Functional abdominal pain syndrome (FAPS) differs from the other functional bowel disorders; it is less common, symptoms largely are unrelated to food intake and defecation, and it has higher comorbidity with psychiatric disorders. The etiology and pathophysiology are incompletely understood. Because FAPS likely represents a heterogeneous group of disorders, peripheral neuropathic pain mechanisms, alterations in endogenous pain modulation systems, or both may be involved in any one patient. The diagnosis of FAPS is made on the basis of positive symptom criteria and a longstanding history of symptoms; in the absence of alarm symptoms, an extensive diagnostic evaluation is not required. Management is based on a therapeutic physician-patient relationship and empirical treatment algorithms using various classes of centrally acting drugs, including antidepressants and anticonvulsants. The choice, dose, and combination of drugs are influenced by psychiatric comorbidities. Psychological treatment options include psychotherapy, relaxation techniques, and hypnosis. Refractory FAPS patients may benefit from a multidisciplinary pain clinic approach.

  16. Shoulder pain in hemiplegia. (United States)

    Andersen, L T


    Development of a painful shoulder in the hemiplegic patient is a significant and serious problem, because it can limit the patient's ability to reach his or her maximum functional potential. Several etiologies of shoulder pain have been identified, such as immobilization of the upper extremity, trauma to the joint structures, including brachial plexus injuries, and subluxation of the gleno-humeral joint. A review of the literature explains the basic anatomy and kinesiology of the shoulder complex, the various etiologies of hemiplegic shoulder pain, and the pros and cons of specific treatment techniques. This knowledge is essential for the occupational therapist to evaluate effectively techniques used to treat the patient with hemiplegic shoulder pain. More effective management of this problem will facilitate the patient's ability to reach his or her maximum functional potential.

  17. Music for pain relief. (United States)

    Cepeda, M S; Carr, D B; Lau, J; Alvarez, H


    The efficacy of music for the treatment of pain has not been established. To evaluate the effect of music on acute, chronic or cancer pain intensity, pain relief, and analgesic requirements. We searched The Cochrane Library, MEDLINE, EMBASE, PsycINFO, LILACS and the references in retrieved manuscripts. There was no language restriction. We included randomized controlled trials that evaluated the effect of music on any type of pain in children or adults. We excluded trials that reported results of concurrent non-pharmacological therapies. Data was extracted by two independent review authors. We calculated the mean difference in pain intensity levels, percentage of patients with at least 50% pain relief, and opioid requirements. We converted opioid consumption to morphine equivalents. To explore heterogeneity, studies that evaluated adults, children, acute, chronic, malignant, labor, procedural, or experimental pain were evaluated separately, as well as those studies in which patients chose the type of music. Fifty-one studies involving 1867 subjects exposed to music and 1796 controls met inclusion criteria. In the 31 studies evaluating mean pain intensity there was a considerable variation in the effect of music, indicating statistical heterogeneity ( I(2) = 85.3%). After grouping the studies according to the pain model, this heterogeneity remained, with the exception of the studies that evaluated acute postoperative pain. In this last group, patients exposed to music had pain intensity that was 0.5 units lower on a zero to ten scale than unexposed subjects (95% CI: -0.9 to -0.2). Studies that permitted patients to select the music did not reveal a benefit from music; the decline in pain intensity was 0.2 units, 95% CI (-0.7 to 0.2). Four studies reported the proportion of subjects with at least 50% pain relief; subjects exposed to music had a 70% higher likelihood of having pain relief than unexposed subjects (95% CI: 1.21 to 2.37). NNT = 5 (95% CI: 4 to 13). Three

    Renton, T


    The issues specific to trigeminal pain include the complexity of the region, the problematic impact on daily function and significant psychological impact (J Dent, 43, 2015, 1203). By nature of the geography of the pain (affecting the face, eyes, scalp, nose, mouth), it may interfere with just about every social function we take for granted and enjoy (J Orofac Pain, 25, 2011, 333). The trigeminal nerve is the largest sensory nerve in the body, protecting the essential organs that underpin our very existence (brain, eyes, nose, mouth). It is no wonder that pain within the trigeminal system in the face is often overwhelming and inescapable for the affected individual. © 2016 John Wiley & Sons A/S.

    Rajagopal, M R; Ito, Kurnia


    There is a lot of unrelieved pain in developing countries. Here is a story from Bali, Indonesia, about a woman with advanced malignancy, who is in unbelievable agony. Expensive chemotherapy is available to her. But although the necessary medications for relieving her pain are available in hospitals, they do not reach the patient, in her home, or even when she is admitted to the hospital, because of ignorance of the medical profession about pain management and because of unnecessary regulatory restrictions. The woman's pain affects the whole family, endangering the family's income and the future of her children. The intervention of palliative care during part of her life gives her some relief, only for the agony to be repeated by pointless chemotherapy and neglect of the suffering during admission to the hospital. Whatever relief could be given to her was because of the intervention of a volunteer with no schooling in medicine or palliative care.

  2. Pain stress and headache. (United States)

    Panerai, Alberto E


    The association between pain and stress is an old one, but still it is not really clear who comes first. Pain induces stress, and stress induces pain. Pain is part of our homeostatic system and in this way is an emotion, i.e., it tells us that something is out-of-order (control), and emotion drives our behavior and one behavior is stress response. Stress comes from ourselves: the imagination we have or would like to have of us, from the image others give of us, from the goals we assume it is necessary to reach for our well-being or the goals others want us to fulfill. Stress comes from our social condition and the condition we would like, stress comes from dangerous situations we cannot control. Headache easily fits in the picture.

  4. Conceptualizing suffering and pain. (United States)

    Bueno-Gómez, Noelia


    This article aims to contribute to a better conceptualization of pain and suffering by providing non-essential and non-naturalistic definitions of both phenomena. Contributions of classical evidence-based medicine, the humanistic turn in medicine, as well as the phenomenology and narrative theories of suffering and pain, together with certain conceptions of the person beyond them (the mind-body dichotomy, Cassel's idea of persons as "intact beings") are critically discussed with such purpose. A philosophical methodology is used, based on the review of existent literature on the topic and the argumentation in favor of what are found as better definitions of suffering and pain. Pain can be described in neurological terms but cognitive awareness, interpretation, behavioral dispositions, as well as cultural and educational factors have a decisive influence on pain perception. Suffering is proposed to be defined as an unpleasant or even anguishing experience, severely affecting a person at a psychophysical and existential level. Pain and suffering are considered unpleasant. However, the provided definitions neither include the idea that pain and suffering can attack and even destroy the self nor the idea that they can constructively expand the self; both perspectives can b e equally useful for managing pain and suffering, but they are not defining features of the same. Including the existential dimension in the definition of suffering highlights the relevance of suffering in life and its effect on one's own attachment to the world (including personal management, or the cultural and social influences which shape it). An understanding of pain and suffering life experiences is proposed, meaning that they are considered aspects of a person's life, and the self is the ever-changing sum of these (and other) experiences. The provided definitions will be useful to the identification of pain and suffering, to the discussion of how to relieve them, and to a better understanding

  5. Colorectal surgery patients' pain status, activities, satisfaction, and beliefs about pain and pain management. (United States)

    Brown, Carolyn; Constance, Kristel; Bédard, Denise; Purden, Margaret


    This study describes surgical colorectal cancer patients' pain levels, recovery activities, beliefs and expectations about pain, and satisfaction with pain management. A convenience sample of 50 adult inpatients who underwent colorectal surgery for cancer participated. Patients were administered the modified American Pain Society Patient Outcome Questionnaire on postoperative day 2 and asked to report on their status in the preceding 24 hours. Patients reported low current (mean 1.70) and average (mean 2.96) pain scores but had higher scores and greater variation for worst pain (mean 5.48). Worst pain occurred mainly while turning in bed or mobilizing, and 25% of patients experienced their worst pain at rest. Overall, patients expected to have pain after surgery and were very satisfied with pain management. Patients with worst pain scores >7 reported interference with recovery activities, mainly general activity (mean 5.67) and walking ability (mean 5.15). These patients were likely to believe that "people can get addicted to pain medication easily" (mean 3.39 out of 5) and that "pain medication should be saved for cases where pain gets worse" (mean 3.20 out of 5). These beliefs could deter patients from seeking pain relief and may need to be identified and addressed along with expectations about pain in the preoperative nursing assessment.

  9. Efficient conditioned pain modulation despite pain persistence in painful diabetic neuropathy. (United States)

    Granovsky, Yelena; Nahman-Averbuch, Hadas; Khamaisi, Mogher; Granot, Michal


    Alleviation of pain, by either medical or surgical therapy, is accompanied by transition from less efficient, or pro-nociceptive, to efficient conditioned pain modulation (CPM). Spontaneous decrease or resolution of pain with disease progression is reported for some patients with painful diabetic neuropathy (PDN). To explore whether CPM changes similarly in parallel to spontaneous resolution of pain in PDN patients. In this cross-sectional study, thirty-three patients with PDN underwent psychophysical assessment of pain modulation on the forearm, remote from the clinical pain. Pain duration was not correlated with neuropathic pain intensity, yet, it correlated with CPM efficiency; patients with longer pain duration had same pain level, but more efficient CPM than those with short-pain duration (ρ = -0.417; P = 0.025, Spearman correlation). Patients with pain more than 2 years (median split) expressed efficient CPM that was not different from that of healthy controls. These patients also had lower temporal summation of pain than the short-pain duration patients group ( P < 0.05). The 2 patient groups did not differ in clinical pain characteristics or use of analgesics. Pro-nociception, expressed by less efficient CPM and high temporal summation that usually accompanies clinical painful conditions, seems to "normalize" with chronicity of the pain syndrome. This is despite continuing pain, suggesting that pro-nociceptivity in pain syndromes is multifactorial. Because the pain modulation profile affects success of therapy, this suggests that different drugs might express different efficacy pending on duration of the pain in patients with PDN.

  10. Prayer and physical pains

    Directory of Open Access Journals (Sweden)

    Nahid Mehran


    Full Text Available Background and Objectives: Prayer is one of the most important religious ordinances and is one of the necessities of Islam. In spite of the progression of medicine science, it is sometimes seen that the mundane subjects become hopeless in curing physical diseases and this time, the hopeless man appeals to the Lord God. This review study was conducted to examine the positive and negative views regarding effectsof prayer on physical pains. Methods: This review article was carried on by studying about 30 related original articles and different scientific texts.  Results:In various studies, it is demonstrated that Islamic worships especially prayer are effective in treating most acute and chronic pains. But despite this, some studies indicate that there is no effectiveness or even there are negative effects of prayer on some physical pains. Conclusion: With regard to the above mentioned results,most studies support the positive effects of prayer on physical pains. So the medical staffs should alsopay attention to this besides medicinal remedies. In addition, by emphasizing on and advertising aboutthe advantages of practices likeprayer in the treatment of chronic pains, it would be possible to prevent people, especially the youth, from taking inadmissible drugs such as alcohol, narcotics or other illegal drugs. Further studies are recommended to explore the effects of prayer on different acute and chronic physical pains.

  11. Functional abdominal pain. (United States)

    Grover, Madhusudan; Drossman, Douglas A


    Functional abdominal pain syndrome (FAPS) is a relatively less common functional gastrointestinal (GI) disorder defined by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods (Drossman Gastroenterology 130:1377-1390, 2006), which points to a more centrally targeted (spinal and supraspinal) basis for the symptoms. However, FAPS is frequently confused with irritable bowel syndrome and other functional GI disorders in which abdominal pain is associated with eating and bowel movements. FAPS also differs from chronic abdominal pain associated with entities such as chronic pancreatitis or chronic inflammatory bowel disease, in which the pain is associated with peripherally acting factors (eg, gut inflammation or injury). Given the central contribution to the pain experience, concomitant psychosocial disturbances are common and strongly influence the clinical expression of FAPS, which also by definition is associated with loss of daily functioning. These factors make it critical to use a biopsychosocial construct to understand and manage FAPS, because gut-directed treatments are usually not successful in managing this condition.

  12. Anorectal and Pelvic Pain. (United States)

    Bharucha, Adil E; Lee, Tae Hee


    Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacological, behavioral, and physical therapy. Opioids should be avoided, and surgical treatment has a limited role, primarily in refractory interstitial cystitis. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    Fu, Kai; Robbins, Sarah R; McDougall, Jason J


    OA is a painful joint disease that predominantly affects the elderly. Pain is the primary symptom of OA, and it can present as either intermittent or constant. OA pain mechanisms are complex and have only recently been determined. Both peripheral and central processes are involved in creating the OA pain experience, making targeted therapy problematic. Nociceptive, inflammatory and neuropathic pains are all known to occur in OA, but to varying degrees in a patient- and time-specific manner. A better understanding of these multifactorial components of OA pain will lead to the development of more effective and safer pain treatments.

  16. Cancer pain management: Basic information for the young pain physicians

    Directory of Open Access Journals (Sweden)

    SPS Rana


    Full Text Available 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.

    To characterize pain related to primary burning mouth syndrome (BMS) in terms of intensity, interference, and distress caused by the pain, as well as factors influencing the pain across a period of 2 weeks, and to study the use of coping and management strategies on a daily basis. Fifty-two female patients with primary BMS completed a 2-week pain diary. Pain intensity, interference, distress, and mood on a 0 to 10 numeric rating scale (NRS), as well as pain amplifying and alleviating factors, were recorded three times a day. The use of treatments (medication or other means) and coping strategies were recorded at the end of each day. Coefficient of variation, repeated measures analysis of variance, and correlative methods were used to assess the between- and within-subject variation, pain patterns, and associations between various pain scores. The overall mean pain intensity score of the 14 diary days was 3.1 (SD: 1.7); there was considerable variation in pain intensity between patients. Most patients experienced intermittent pain. On average, pain intensity increased from the morning to the evening. Intercorrelations between pain intensity, interference, distress, and mood were high, varying between rs = .75 and rs = .93 (P < .001). Pungent or hot food or beverages, stress, and tiredness were the most frequently mentioned pain-amplifying factors. The corresponding pain-alleviating factors were eating, sucking pastilles, drinking cold beverages, and relaxation. Thirty (58%) patients used pain medication and 35% reported using other means to alleviate their BMS pain. There was large variation in the use of coping strategies -between subjects. There were considerable differences in pain, in factors influencing the pain, and in pain behavior across BMS patients. This indicates that patient information and education as well as treatment of BMS pain should be individualized.

  18. Fear of pain in children and adolescents with neuropathic pain and complex regional pain syndrome. (United States)

    Simons, Laura E


    A significant proportion of children and adolescents with chronic pain endorse elevated pain-related fear. Pain-related fear is associated with high levels of disability, depressive symptoms, and school impairment. Because of faulty nerve signaling, individuals with neuropathic pain and complex regional pain syndrome may be more prone to develop pain-related fear as they avoid use of and neglect the affected body area(s), resulting in exacerbated symptoms, muscle atrophy, maintenance of pain signaling, and ongoing pain-related disability. Not surprisingly, effective treatments for elevated pain-related fears involve exposure to previously avoided activities to downregulate incorrect pain signaling. In the context of intensive interdisciplinary pain treatment of youth with neuropathic pain, decreasing pain-related fear is associated with improved physical and psychological functioning, whereas high initial pain-related fear is a risk factor for less treatment responsiveness. An innovative approach to targeting pain-related fear and evidence of a neural response to treatment involving decoupling of the amygdala with key fear circuits in youth with complex regional pain syndrome suggest breakthroughs in our ability to ameliorate these issues.

  19. The periodontal pain paradox: Difficulty on pain assesment in dental patients (The periodontal pain paradox hypothesis

    Directory of Open Access Journals (Sweden)

    Haryono Utomo


    Full Text Available In daily dental practice, the majority of patients’ main complaints are related to pain. Most patients assume that all pains inside the oral cavity originated from the tooth. One particular case is thermal sensitivity; sometimes patients were being able to point the site of pain, although there is neither visible caries nor secondary caries in dental radiograph. In this case, gingival recession and dentin hypersensitivity are first to be treated to eliminate the pain. If these treatments failed, pain may misdiagnose as pulpal inflammation and lead to unnecessary root canal treatment. Study in pain during periodontal instrumentation of plaque-related periodontitis revealed that the majority of patients feel pain and discomfort during probing and scaling. It seems obvious because an inflammation, either acute or chronic is related to a lowered pain threshold. However, in contrast, in this case report, patient suffered from chronic gingivitis and thermal sensitivity experienced a relative pain-free sensation during probing and scaling. Lowered pain threshold which accompanied by a blunted pain perception upon periodontal instrumentation is proposed to be termed as the periodontal pain paradox. The objective of this study is to reveal the possibility of certain factors in periodontal inflammation which may involved in the periodontal pain paradox hypothesis. Patient with thermal hypersensitivity who was conducted probing and scaling, after the relative pain-free instrumentation, thermal hypersensitivity rapidly disappeared. Based on the successful periodontal treatment, it is concluded that chronic gingivitis may modulate periodontal pain perception which termed as periodontal pain paradox

  20. Pain as social glue: shared pain increases cooperation. (United States)

    Bastian, Brock; Jetten, Jolanda; Ferris, Laura J


    Even though painful experiences are employed within social rituals across the world, little is known about the social effects of pain. We examined the possibility that painful experiences can promote cooperation within social groups. In Experiments 1 and 2, we induced pain by asking some participants to insert their hands in ice water and to perform leg squats. In Experiment 3, we induced pain by asking some participants to eat a hot chili pepper. Participants performed these tasks in small groups. We found evidence for a causal link: Sharing painful experiences with other people, compared with a no-pain control treatment, promoted trusting interpersonal relationships by increasing perceived bonding among strangers (Experiment 1) and increased cooperation in an economic game (Experiments 2 and 3). Our findings shed light on the social effects of pain, demonstrating that shared pain may be an important trigger for group formation. © The Author(s) 2014.

  2. Pain Sensitivity and Pain Catastrophizing are Associated with Persistent Pain and Disability after Lumbar Spine Surgery (United States)

    Coronado, Rogelio A.; George, Steven Z.; Devin, Clinton J.; Wegener, Stephen T.; Archer, Kristin R.


    Objective To examine whether pain sensitivity and pain catastrophizing are associated with persistent pain and disability after lumbar spine surgery. Design Prospective observational cohort study. Setting Academic medical center. Participants Patients (N = 68, mean ± SD age = 57.9 ± 13.1 years, N female = 40 (58.8%)) undergoing spine surgery for a degenerative condition from March 1, 2012 to April 30, 2013 were assessed 6 weeks, 3 months, and 6 months after surgery. Interventions Not applicable. Main Outcome Measure(s) The main outcome measures were persistent back pain intensity, pain interference, and disability. Patients with persistent back pain intensity, pain interference, or disability were identified as those patients reporting Brief Pain Inventory scores ≥ 4 and Oswestry Disability Index scores ≥ 21 at all postoperative time points. Results From 6 weeks to 6 months after surgery, approximately 12.9%, 24.2%, and 46.8% of patients reported persistent back pain intensity, pain interference, or disability, respectively. Increased pain sensitivity at 6 weeks was associated with having persistent back pain intensity (OR = 2.0, 95% CI = 1.0; 4.1) after surgery. Increased pain catastrophizing at 6 weeks was associated with having persistent back pain intensity (OR = 1.1, 95% CI = 1.0; 1.2), pain interference (OR = 1.1, 95% CI = 1.0; 1.2), and disability (OR = 1.3, 95% CI = 1.1; 1.4). An interaction effect was not found between pain sensitivity and pain catastrophizing on persistent outcomes (p > 0.05). Conclusion(s) Findings suggest the importance of early postoperative screening for pain sensitivity and pain catastrophizing in order to identify patients at-risk for poor postoperative pain intensity, interference, and/or disability outcomes. Future research should consider the benefit of targeted therapeutic strategies for patients with these postoperative prognostic factors. PMID:26101845

  3. Pain Adaptability in Individuals With Chronic Musculoskeletal Pain Is Not Associated With Conditioned Pain Modulation. (United States)

    Wan, Dawn Wong Lit; Arendt-Nielsen, Lars; Wang, Kelun; Xue, Charlie Changli; Wang, Yanyi; Zheng, Zhen


    Healthy humans can be divided into the pain adaptive (PA) and the pain nonadaptive (PNA) groups; PA showed a greater decrease in pain rating to a cold pressor test (CPT) than PNA. This study examined if the dichotomy of pain adaptability existed in individuals with chronic musculoskeletal pain. CPTs at 2°C and 7°C were used to assess the status of pain adaptability in participants with either chronic nonspecific low back pain or knee osteoarthritis. The participants' potency of conditioned pain modulation (CPM) and local inhibition were measured. The strengths of pain adaptability at both CPTs were highly correlated. PA and PNA did not differ in their demographic characteristics, pain thresholds from thermal and pressure stimuli, or potency of local inhibition or CPM. PA reached their maximum pain faster than PNA (t 41 = -2.76, P adaptability exists in musculoskeletal pain patients. Consistent with the healthy human study, the strength of pain adaptability and potency of CPM are not related. Pain adaptability could be another form of endogenous pain inhibition of which clinical implication is yet to be understood. The dichotomy of pain adaptability was identified in healthy humans. The current study confirms that this dichotomy also exists in individuals with chronic musculoskeletal pain, and could be reliably assessed with CPTs at 2°C and 7°C. Similar to the healthy human study, pain adaptability is not associated with CPM, and may reflect the temporal aspect of pain inhibition. Copyright © 2018 The American Pain Society.

    van Lankveld, Jacques J D M; Granot, Michal; Weijmar Schultz, Willibrord C M; Binik, Yitzchak M; Wesselmann, Ursula; Pukall, Caroline F; Bohm-Starke, Nina; Achtrari, Chahin


    Women's sexual pain disorders include dyspareunia and vaginismus and there is need for state-of-the-art information in this area. To update the scientific evidence published in 2004, from the 2nd International Consultation on Sexual Medicine pertaining to the diagnosis and treatment of women's sexual pain disorders. An expert committee, invited from six countries by the 3rd International Consultation, was comprised of eight researchers and clinicians from biological and social science disciplines, for the purpose of reviewing and grading the scientific evidence on nosology, etiology, diagnosis, and treatment of women's sexual pain disorders. Expert opinion was based on grading of evidence-based medical literature, extensive internal committee discussion, public presentation, and debate. Results. A comprehensive assessment of medical, sexual, and psychosocial history is recommended for diagnosis and management. Indications for general and focused pelvic genital examination are identified. Evidence-based recommendations for assessment of women's sexual pain disorders are reviewed. An evidence-based approach to management of these disorders is provided. Continued efforts are warranted to conduct research and scientific reporting on the optimal assessment and management of women's sexual pain disorders, including multidisciplinary approaches.

  5. Cannabinoids and Pain

    Directory of Open Access Journals (Sweden)

    J Michael Walker


    Full Text Available Cannabinoids have been used to treat pain for many centuries. However, only during the past several decades have rigorous scientific methods been applied to understand the mechanisms of cannabinoid action. Cannabinoid receptors were discovered in the late 1980s and have been found to mediate the effects of cannabinoids on the nervous system. Several endocannabinoids were subsequently identified. Many studies of cannabinoid analgesia in animals during the past century showed that cannabinoids block all types of pain studied. These effects were found to be due to the suppression of spinal and thalamic nociceptive neurons, independent of any actions on the motor systems. Spinal, supraspinal and peripheral sites of cannabinoid analgesia have been identified. Endocannabinoids are released upon electrical stimulation of the periaqueductal gray, and in response to inflammation in the extremities. These observations and others thus suggest that a natural function of cannabinoid receptors and their endogenous ligands is to regulate pain sensitivity. The therapeutic potential of cannabinoids remains an important topic for future investigations, with previous work suggesting utility in clinical studies of cancer and surgical pain. New modes of delivery and/or new compounds lacking the psychotropic properties of the standard cannabinoid ligands offer promise for cannabinoid therapeutics for pain.

  6. 15. Amygdala pain mechanisms (United States)

    Neugebauer, Volker


    A limbic brain area the amygdala plays a key role in emotional responses and affective states and disorders such as learned fear, anxiety and depression. The amygdala has also emerged as an important brain center for the emotional-affective dimension of pain and for pain modulation. Hyperactivity in the laterocapsular division of the central nucleus of the amygdala (CeLC, also termed the “nociceptive amygdala”) accounts for pain-related emotional responses and anxiety-like behavior. Abnormally enhanced output from the CeLC is the consequence of an imbalance between excitatory and inhibitory mechanisms. Impaired inhibitory control mediated by a cluster of GABAergic interneurons in the intercalated cell masses (ITC) allows the development of glutamate- and neuropeptide-driven synaptic plasticity of excitatory inputs from the brainstem (parabrachial area) and from the lateral-basolateral amygdala network (LA-BLA, site of integration of polymodal sensory information). BLA hyperactivity also generates abnormally enhanced feedforward inhibition of principal cells in the medial prefrontal cortex (mPFC), a limbic cortical area that is strongly interconnected with the amygdala. Pain-related mPFC deactivation results in cognitive deficits and failure to engage cortically driven ITC-mediated inhibitory control of amygdala processing. Impaired cortical control allows the uncontrolled persistence of amygdala pain mechanisms. PMID:25846623

  7. Pain-relevant anxiety affects desire for pain relief, but not pain perception

    Directory of Open Access Journals (Sweden)

    Adriana Banozic


    Full Text Available Background: Pain context plays a significant role in the perception of pain. Despite recent interest in vicarious learning and anxiety in pain modulation, there have been no attempts to explore pain modulation by specific environmental cues. Aims: Therefore, the present study evaluated pain responses in the condition that was attributed as either anxiety relevant (AR or anxiety irrelevant. Materials and Methods: Participants were exposed to both conditions through social observational learning. Pain perception was assessed by means of a visual analog scale ranging from 0 = no pain to 10 = maximum imaginable pain. State anxiety, empathy, expectancy, and desire for pain relief were also measured at both neutral and emotionally inducing conditions. Results: No effect of relevancy of anxiety for the pain context on any of the pain-related constructs was found. However, participants in the AR condition reported an increased desire for pain relief. Maximizing similarities between observed and experienced pain context did not enhance observational learning effects in the emotionally inducing condition regardless of its relevance, but significant changes were found in comparison to the affectively neutral group. Conclusions: These results could have potentially significant clinical implications suggesting that even though observing painful procedures does not increase pain it could affect medication usage.

A prerequisite for being able to alleviate pain is that we areable to recognize it. Potential behavioural signs of pain were investigated for dairy cattle with the aimof constructing a pain scale for use under production conditions. Forty-three cows were...

  9. In vivo T-cell depletion using alemtuzumab in family and unrelated donor transplantation for pediatric non-malignant disease achieves engraftment with low incidence of graft vs. host disease. (United States)

    Saif, M A; Borrill, R; Bigger, B W; Lee, H; Logan, A; Poulton, K; Hughes, S; Turner, A J; Bonney, D K; Wynn, R F


    In vivo T-cell depletion, using alemtuzumab therapy prior to SCT, can reduce the incidence of GVHD. This treatment has a potential to delay immune reconstitution resulting in increased morbidity due to viral illnesses. We retrospectively analyzed data on all pediatric patients with non-malignant disorders who received alemtuzumab-based conditioning regimens in our center over the last 10 yr (n = 91). Our data show an OS of 91.2%. The incidence of acute (grade 2-4) GVHD was 18.7% and that of chronic GVHD 5.5%. Viremia due to adenovirus, EBV and CMV was seen in 19.8%, 64.8% and 39.6% patients, respectively, with only two deaths attributed to viral infection (adenovirus). Chimerism level at three month was predictive of graft outcome. Nine patients, who had graft failure after first SCT, were salvaged with a second SCT using RIC and same donor (if available). Based on these results, we conclude that the use of in vivo T-cell depletion is safe, achieves good chimerism and does not lead to increased morbidity and mortality due to viral infections. It is associated with a reduced incidence of chronic GVHD. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  10. Resolution of pain after childbirth. (United States)

    Eisenach, James C; Pan, Peter; Smiley, Richard M; Lavand'homme, Patricia; Landau, Ruth; Houle, Timothy T


    Chronic pain after surgery occurs in 10-40% of individuals, including 5-20% of women after cesarean delivery in previous reports. Pain and depression 2 months after childbirth are independently associated with more severe acute post-delivery pain. Here we examine other predictors of pain at 2 months and determine the incidence of pain at 6 and 12 months after childbirth. Following Institutional Review Board approval, 1228 women were interviewed within 36 h of delivery. Of these, 937 (76%) were successfully contacted by telephone at 2 months, and, if they had pain, at 6 and 12 months after delivery. The primary outcome measure was presence of pain which began at the time of delivery. We also generated a model of severity of acute post-delivery pain and 2 month pain and depression. Pain which began at the time of delivery was remarkably rare 6 and 12 months later (1.8% and 0.3% [upper 95% confidence limit, 1.2%], respectively). Past history of pain and degree of tissue damage at delivery accounted for 7.0% and 16.7%, respectively, of one aspect in the variability in acute post-delivery pain. Neither of these factors was associated with incidence of pain 2 months later. Using a definition of new onset pain from delivery, we show a remarkably low incidence of pain 1 yr after childbirth, including those with surgical delivery. Additionally, degree of tissue trauma and history of chronic pain, risk factors for pain 2 months after other surgery, were unimportant to pain 2 months after cesarean or vaginal delivery.

  11. Right upper quadrant pain

    Ralls, P.W.; Colletti, P.M.; Boswell, W.D. Jr.; Halls, J.M.


    Historically, assessment of acute right upper quadrant abdominal pain has been a considerable clinical challenge. While clinical findings and laboratory data frequently narrow the differential diagnosis, symptom overlap generally precludes definitive diagnosis among the various diseases causing acute right upper quadrant pain. Fortunately, the advent of newer diagnostic imaging modalities has greatly improved the rapidity and reliability of diagnosis in these patients. An additional challenge to the physician, with increased awareness of the importance of cost effectiveness in medicine, is to select appropriate diagnostic schema that rapidly establish accurate diagnoses in the most economical fashion possible. The dual goals of this discussion are to assess not only the accuracy of techniques used to evaluate patients with acute right upper quadrant pain, but also to seek out cost-effective, coordinated imaging techniques to achieve this goal

    Louise Hide, Joanna Bourke, Carmen Mangion


    Full Text Available This issue of '19' has been guest edited by Louise Hide, Joanna Bourke, and Carmen Mangion. Collectively, we comprise the Birkbeck Pain Project, a three-year Wellcome Trust funded project that is led by Joanna Bourke. We are particularly interested in understanding how the meaning of pain - for sufferers, physicians, and other witnesses - changed over time. In this issue, articles by social and cultural historians, as well as literary scholars, examine and analyse the implications of shifting discourses in personal narratives as well as in religious communities, and in philosophical, medical, and psychiatric texts. By analysing language within current theories of the time, we can deepen our understanding of the complex interaction between the body, mind, and culture to gain insights into the ever-changing subjective experience of pain.

  13. Pain management in ER

    Directory of Open Access Journals (Sweden)

    Anna Burattin


    Full Text Available For over 30 years, the International Association for the Study of Pain has defined pain as «an unpleasant sensorial and emotional experience associated to real or potential tissue damage». Today, evident shortcomings still exist in the use of adequate analgesia, especially in the emergency medicine context: pain is the most common symptom amongst the Emergency Department patients (reaching a prevalence of over 60%, however, statistics reported in literature show that only 45% of patients receive analgesic prescriptions on discharge. In recent years, the influence of changes connected to accreditation standards has generated new expectations of healthcare professionals; although this aspect connected to the evolution of public health provides a stimulus to the evolution of the practical aspect of everyday clinical work, we must not forget that doctors take the Hippocratic oath, the ethical obligation to treat suffering and pain, which is especially pertinent to doctors working in Emergency conditions. The quality of the service provided with regard to pain-relief in ED cannot exclude an analysis of the local situation, the definition of roles, the extrinsication of potential with the ultimate aim of providing a service as close as possible to user hopes. Organisational efforts must be directed at reaching excellent quality levels, in which the monitoring of the activities performed takes place through the registration and periodic re-evaluation of the deriving data. Through this observational, prospective study, we intend to evaluate the effective prevalence of the pain symptom in the Emergency Department and the impact of the use of different classes of analgesia, also estimating the latency between the onset of the symptom and triage in order to quantify the efficacy of the analgesia practiced.

    Full Text Available BACKGROUND Pain management in Polytrauma is a poorly-addressed concern at the time of active resuscitation. But, very often, pain assessment is also a challenge! Opioids belong to conventional analgesics of choice in any acute pain conditions. But, recently application of regional anaesthesia techniques and subanaesthetic doses of ketamine are satisfactorily employed. A clear understanding of neuropathic element of pain must be made as they require specific therapy. It must be emphasised that effective pain therapy is a multidisciplinary team work with active involvement of pain psychologist.

  15. Chronic Pain in Neurosurgery. (United States)

    Grodofsky, Samuel


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

  16. Oxcarbazepine for neuropathic pain. (United States)

    Zhou, Muke; Chen, Ning; He, Li; Yang, Mi; Zhu, Cairong; Wu, Fengbo


    Several anticonvulsant drugs are used in the management of neuropathic pain. Oxcarbazepine is an anticonvulsant drug closely related to carbamazepine. Oxcarbazepine has been reported to be efficacious in the treatment of neuropathic pain, but evidence from randomised controlled trials (RCTs) is conflicting. Oxcarbazepine is reportedly better tolerated than carbamazepine. This is the first update of a review published in 2013. To assess the benefits and harms of oxcarbazepine for different types of neuropathic pain. On 21 November 2016, we searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE and Embase. We searched the Chinese Biomedical Retrieval System (January 1978 to November 2016). We searched the US National Institutes of Health (NIH) databases and the World Health Organization (WHO) International Clinical Trials Registry Platform for ongoing trials in January 2017, and we wrote to the companies who make oxcarbazepine and to pain experts requesting additional information. All RCTs and randomised cross-over studies of oxcarbazepine for the treatment of people of any age or sex with any neuropathic pain were eligible. We planned to include trials of oxcarbazepine compared with placebo or any other intervention with a treatment duration of at least six weeks, regardless of administration route and dose. We used standard methodological procedures expected by Cochrane. Five multicentre, randomised, placebo-controlled, double-blind trials with a total of 862 participants were eligible for inclusion in this updated review. Three trials involved participants with painful diabetic peripheral neuropathy (DPN) (n = 634), one included people with neuropathic pain due to radiculopathy (n = 145), and one, which was newly identified at this update, involved participants with peripheral neuropathic pain of mixed origin (polyneuropathy, peripheral nerve injury or postherpetic neuralgia) (n = 83). Some studies did not report all outcomes of interest. For

  19. Reward and motivation in pain and pain relief (United States)

    Navratilova, Edita; Porreca, Frank


    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.

  20. [Pain and Christianity. A symbol for overcoming pain?]. (United States)

    Markschies, C


    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.

  1. Understanding cultural influences on back pain and back pain research. (United States)

    Henschke, Nicholas; Lorenz, Eva; Pokora, Roman; Michaleff, Zoe A; Quartey, Jonathan N A; Oliveira, Vinicius Cunha


    Low back pain is highly prevalent and places a considerable burden on individuals, their families and communities. This back pain burden is unequally distributed around the world and within populations. Clinicians and researchers addressing back pain should be aware of the cultural, social and political context of back pain patients and how this context can influence pain perception, disability and health care use. Culture, which influences the beliefs and behaviour of individuals within a social group, could be considered an important contributor to the unequal distribution of back pain. However, there is paucity of high-quality research exploring the influence of culture on the experience and management of back pain. Further development and testing of specific tools, assessment methods and communication strategies are needed to improve our understanding of how cultural practices, values and identifications affect those dealing with back pain.

  2. Altering gender role expectations: effects on pain tolerance, pain threshold, and pain ratings. (United States)

    Robinson, Michael E; Gagnon, Christine M; Riley, Joseph L; Price, Donald D


    The literature demonstrating sex differences in pain is sizable. Most explanations for these differences have focused on biologic mechanisms, and only a few studies have examined social learning. The purpose of this study was to examine the contribution of gender-role stereotypes to sex differences in pain. This study used experimental manipulation of gender-role expectations for men and women. One hundred twenty students participated in the cold pressor task. Before the pain task, participants were given 1 of 3 instructional sets: no expectation, 30-second performance expectation, or a 90-second performance expectation. Pain ratings, threshold, and tolerance were recorded. Significant sex differences in the "no expectation" condition for pain tolerance (t = 2.32, df = 38, P differ in their pain tolerance, pain threshold, or pain ratings. This is the first empirical study to show that manipulation of expectations alters sex differences in laboratory pain.

  3. [Tips for taking history of pain]. (United States)

    Noda, Kazutaka; Ikusaka, Masatomi


    Pain is physiologically classified as nociceptive pain, neuropathic pain, and psychogenic pain. Nociceptive pain is further divided into visceral pain, somatic pain, and referred pain. Visceral pain is dull, and it is difficult to locate the origin of such pain. Somatic pain is sharp, severe, and well localized. On receiving visceral input for pain, it affects somatic nerve inputting to the same spinal segments, then referred pain is felt in the skin and muscles supplied by it. Referred pain is felt in an area that is located at a distance from its cause. History taking is the most important factor for determining the cause of pain. Generally, all the necessary information regarding pain can be acquired if pain-related history is obtained using the "OPQRST" mnemonic, that is, onset, provocation/palliative factor, quality, region/radiation/related symptoms, severity, and time characteristics.

  4. Menopause affects pain depending on pain type and characteristics. (United States)

    Meriggiola, Maria Cristina; Nanni, Michela; Bachiocco, Valeria; Vodo, Stellina; Aloisi, Anna M


    Women are more affected than men by many chronic pain conditions, suggesting the effect of sex-related mechanisms in their occurrence. The role of gonadal hormones has been studied but with contrasting results depending on the pain syndrome, reproductive status, and hormone considered. The aim of the present study was to evaluate the pain changes related to the menopausal transition period. In this observational study, postmenopausal women were asked to evaluate the presence of pain in their life during the premenopausal and postmenopausal periods and its modification with menopause. One hundred one women were enrolled and completed questionnaires on their sociodemographic status, pain characteristics, and evolution. The most common pain syndromes were headache (38%), osteoarticular pain (31%), and cervical/lumbar pain (21%). Pain was present before menopause in 66 women, ceased with menopause in 17, and started after menopause in 18. Data were used for cluster analysis, which allowed the division of participants into four groups. In the first, all women experienced headaches that disappeared or improved with menopause. The second group included osteoarticular pain; the pain improved in half of these women and remained stable in the other half. The third group had cervical/lumbar pain, which disappeared or improved with menopause in all. The fourth group presented different kinds of moderate pain, which worsened in all. The present study provides preliminary data suggesting that menopause can affect pain depending on the painful condition experienced by the woman. This underlines the different interactions of menopause-related events with body structures involved in pain.

Methods: The seven-item version of painDETECT provides an overall score that targets only sensory symptoms, while the nine-item version adds responses on two items to the overall score, covering pain course pattern and pain radiation. Both versions have relevance in terms of characterizing broad NeP. The nine- and seven-item versions of painDETECT were administered to subjects with confirmed NeP across six conditions identified during office visits to US community-based physicians. Responses on the sensory symptom items were dichotomized into “at least moderate” (ie, moderate, strongly, very strongly relative to the combined other responses (never, hardly noticed, slightly. Logistic regression of dichotomized variables on the total painDETECT score provided probabilities of experiencing each symptom across the range of painDETECT scores. Results: Both painDETECT versions discriminated among the symptoms with similar probabilities across the score ranges. Using these data, the probability of moderately experiencing each pain sensory item was estimated for a particular score, providing a pain profile. Additionally, the likelihood of experiencing each sensation was determined for a discrete increase in score, ie, the odds of at least a moderate sensation of burning (versus less than a moderate sensation was 1.29 for a 1-point increase, 3.52 for a 5-point increase, and 12.42 for every 10-point increase in the nine-item painDETECT score

  12. Cognitive hypnotherapy for pain management. (United States)

    Elkins, Gary; Johnson, Aimee; Fisher, William


    Pain is a serious health care problem and there is growing evidence to support the use of hypnosis and cognitive-behavioral interventions for pain management. This article reviews clinical techniques and methods of cognitive hypnotherapy for pain management. Current research with emphasis given to randomized, controlled trials is presented and the efficacy of hypnotherapy for pain management is discussed. Evidence for cognitive hypnotherapy in the treatment in chronic pain, cancer, osteoarthritis, sickle cell disease, temporomandibular disorder, fibromyalgia, non-cardiac chest pain, and disability related chronic pains are identified. Implications for clinical practice and research are discussed in light of the accumulating evidence in support of the efficacy and effectiveness of cognitive hypnotherapy for pain management.

  1. Patellofemoral pain in athletes (United States)

    Petersen, Wolf; Rembitzki, Ingo; Liebau, Christian


    Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with signs of patellofemoral osteoarthritis (PFOA). A key factor in PFPS development is dynamic valgus of the lower extremity, which leads to lateral patellar maltracking. Causes of dynamic valgus include weak hip muscles and rearfoot eversion with pes pronatus valgus. These factors can also be observed in patients with PFOA. The available evidence suggests that patients with PFP are best managed with a tailored, multimodal, nonoperative treatment program that includes short-term pain relief with nonsteroidal anti-inflammatory drugs (NSAIDs), passive correction of patellar maltracking with medially directed tape or braces, correction of the dynamic valgus with exercise programs that target the muscles of the lower extremity, hip, and trunk, and the use of foot orthoses in patients with additional foot abnormalities.

  3. Pain and microcrystalline arthritis

    Directory of Open Access Journals (Sweden)

    R. Ramonda


    Full Text Available Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU, responsible for the gout, calcium pyrophosphate (CPP, which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthritis. In this context, the microcrystal arthritis is characterized by multiple, acute attacks followed by chronic pain, disability, impaired quality of life, and increased mortality. Given their chronic nature, they represent an ever more urgent public health problem. MSU and CPP crystals are also able to activate nociceptors. The pain in mycrocrystalline arthritis (MCA is an expression of the inflammatory process. In the course of these diseases there is an abundant release of inflammatory molecules, including prostaglandins 2 and kinins. Interleukin-1 represents the most important cytokine released during the crystal-induced inflammatory process. Therefore, clinically, pain is the most important component of MCA, which lead to functional impairment and disability in a large proportion of the population. It is fundamental to diagnose these diseases as early as possible, and to this aim, to identify appropriate and specific targets for a timely therapeutic intervention.

  10. Pain and consciousness. (United States)

    Garcia-Larrea, Luis; Bastuji, Hélène


    The aversive experience we call "pain" results from the coordinated activation of multiple brain areas, commonly described as a "pain matrix". This is not a fixed arrangement of structures but rather a fluid system composed of several interacting networks: A 'nociceptive matrix' includes regions receiving input from ascending nociceptive systems, and ensures the bodily characteristics of physical pain. A further set of structures receiving secondary input supports the 'salience' attributes of noxious stimuli, triggers top-down cognitive controls, and -most importantly- ensures the passage from pre-conscious nociception to conscious pain. Expectations and beliefs can still modulate the conscious experience via activity in supramodal regions with widespread cortical projections such as the ventral tegmental area. Intracortical EEG responses in humans show that nociceptive cortical processing is initiated in parallel in sensory, motor and limbic areas; it progresses rapidly to the recruitment of anterior insular and fronto-parietal networks, and finally to the activation of perigenual, posterior cingulate and hippocampal structures. Functional connectivity between sensory and high-level networks increases during the first second post-stimulus, which may be determinant for access to consciousness. A model is described, progressing from unconscious sensori-motor and limbic processing of spinothalamic and spino-parabrachial input, to an immediate sense of awareness supported by coordinated activity in sensorimotor and fronto-parieto-insular networks, and leading to full declarative consciousness through integration with autobiographical memories and self-awareness, involving posterior cingulate and medial temporal areas. This complete sequence is only present during full vigilance states. We contend, however, that even in unconscious subjects, repeated limbic and vegetative activation by painful stimuli via spino-amygdalar pathways can generate implicit memory traces and

  15. Pain Scores Are Not Predictive of Pain Medication Utilization

    Directory of Open Access Journals (Sweden)

    Suzanne Galloway


    Full Text Available Objective. To compare Visual Analogue Scale (VAS scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94. We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA or RN administered (intravenous or oral medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

  16. Biobehavioral pain profile in individuals with chronic spine pain. (United States)

    Matteliano, Deborah; Scherer, Yvonne Krall; Chang, Yu-Ping


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

  17. Alexithymic trait, painful heat stimulation and everyday pain experience

    Directory of Open Access Journals (Sweden)

    Olga ePollatos


    Full Text Available Background: Alexithymia was found to be associated with a variety of somatic complaints including somatoform pain symptoms. This study addressed the question of whether the different facets of alexithymia are related to responses in heat pain stimulation and its interrelations with levels of everyday pain as assessed by self report. Methods: In the study, sensitivity to heat pain was assessed in fifty healthy female participants. Alexithymia facets were assessed by the Toronto Alexithymia Scale. Pain threshold and tolerance were determined using a testing the limits procedure. Participants furthermore rated subjective intensities and unpleasantness of tonic heat stimuli (45.5 C to 47.5 C on visual analogue scales and on a questionnaire. Possible confounding with temperature sensitivity and mood was controlled. Everyday pain was assessed by self-report addressing everyday pain frequency, intensity and impairment experienced over the last two months. Results: Main results were that the facets of alexithymia were differentially associated with pain perception. The affective scale difficulties in describing feelings was associated with hyposensitivity to pain as indicated by higher pain tolerance scores. Furthermore, everyday pain frequency was related to increased alexithymia values on the affective scale difficulties in identifying feelings, whereas higher values on the cognitive alexithymia scale externally oriented thinking were related to lower pain impairment and intensity. Conclusions: We conclude that the different facets of alexithymia are related to alternations in pain processing. Further research on clinical samples is necessary to elucidate whether different aspects of alexithymia act as vulnerability factor for the development of pain symptoms.

  18. Hypnosis and pain in children. (United States)

    Wood, Chantal; Bioy, Antoine


    The development of studies on neuroimaging applied to hypnosis and to the study of pain not only helps to validate the existence of a hypnotic state but also to ratify its therapeutic effects. These studies also enable us to understand how hypnosis is effective on the cortical level. It also helps us see, from another perspective, the mechanisms of pain leading perhaps to a different definition of pain. This article develops the latest knowledge in the domain of hypnosis and pain, and approaches the clinical practices and their applications in the management of pain in children.

  2. Pain in the hip joint

    Directory of Open Access Journals (Sweden)

    Yuri Aleksandrovich Olyunin


    Full Text Available Pathological changes that develop in the hip joints (HJ have different origins and mechanisms of development, but their main manifestation is pain. The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

  4. Interventional radiology in pain treatment

    International Nuclear Information System (INIS)

    Kastler, B.


    Disease whether it is acute, chronic, or at end stage, is all too regularly accompanied by pain. Pain is often difficult to control, in malignant disease in particular, even by using appropriate medications. Anesthesiologists and pain therapists have developed new invasive therapies including nerve block, sympatholysis, and neurolysis useful for both diagnosis and pain management. To insure the efficiency and safety of these procedures, and furthermore for elaborate techniques such as vertebroplasty, cementoplasty, and radio frequency bone ablation, imaging guidance becomes mandatory. This state-of-the-art book describes the techniques elaborated by interventional radiologists in the treatment and palliation of a variety of benign and malignant painful conditions. Each chapter written by an expert in the field concentrates on a particular aspect of pain management, with emphasis on practical issues. This book will serve as an invaluable source of information for the radiologist willing to learn about new pain therapy techniques aimed at optimizing or replacing more invasive traditional methods.

    Geurts, J W; Haumann, J; van Kleef, M


    The diagnosis and treatment of orofacial pain can be complex. The differential diagnosis is very extensive. Therefore, multidisciplinary diagnosis and treatment are often indicated. The diagnosis of chronic pain also entails the investigation of psychological factors. This is because psychological problems can play a role in the chronification of pain, but they can also be a consequence of chronic pain. Patients with persistent orofacial complaints should be seen by a medical team consisting of an oral and maxillofacial surgeon, a neurologist, an anaesthesiologist/pain specialist, a dentist-gnathologist, an orofacial physical therapist, and a psychologist or psychiatrist specialising in orofacial pain. Treatment options should be discussed, taking into account literature concerning their effectiveness. The general conclusion is that much research remains to be done into the causes of, and treatments for, orofacial pain.

  8. Craniofacial Pain: Brainstem Mechanisms

    Directory of Open Access Journals (Sweden)

    Barry J Sessle


    Full Text Available This article reviews recent research advances in animals that have identified critical neural elements in the brainstem receiving and transmitting craniofacial nociceptive inputs, as well as some of the mechanisms involved in the modulation and plasticity of nociceptive transmission. Nociceptive neurones in the trigeminal (V brainstem sensory nuclear complex can be classified as nociceptive-specific (NS or wide dynamic range (WDR. Some of these neurones respond exclusively to sensory inputs evoked by stimulation of facial skin or oral mucosa and have features suggesting that they are critical neural elements involved in the ability to localize an acute superficial pain and sense its intensity and duration. Many of the V brainstem nociceptive neurones, however, receive convergent inputs from afferents supplying deep craniofacial tissues (eg, dural vessel, muscle and skin or mucosa. These neurones are likely involved in deep pain, including headache, because few nociceptive neurones receive inputs exclusively from afferents supplying these tissues. These extensive convergent input patterns also appear to be important factors in pain spread and referral, and in central mechanisms underlying neuroplastic changes in V neuronal properties that may occur with injury and inflammation. For example, application of the small fibre excitant and inflammatory irritant mustard oil into the temporomandibular joint, masseter or tongue musculature induces a prolonged but reversible enhancement of responses to cutaneous and deep afferent inputs of most WDR and NS neurones. These effects may be accompanied by increased electromyographic activity reflexly induced in the masticatory muscles by mustard oil, and involve endogenous N-methyl-D-aspartate and opioid neurochemical mechanisms. Such peripherally induced modulation of brainstem nociceptive neuronal properties reflects the functional plasticity of the central V system, and may be involved in the development of

    LLopis, Eva; Padron, Mario


    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries

  11. Dysfunctional pain modulation in somatoform pain disorder patients. (United States)

    Klug, Stefanie; Stefanie, Klug; Anderer, Peter; Peter, Anderer; Saletu-Zyhlarz, Gerda; Gerda, Saletu-Zyhlarz; Freidl, Marion; Marion, Freidl; Saletu, Bernd; Bernd, Saletu; Prause, Wolfgang; Wolfgang, Prause; Aigner, Martin; Martin, Aigner


    To date, pain perception is thought to be a creative process of modulation carried out by an interplay of pro- and anti-nociceptive mechanisms. Recent research demonstrates that pain experience constitutes the result of top-down processes represented in cortical descending pain modulation. Cortical, mainly medial and frontal areas, as well as subcortical structures such as the brain stem, medulla and thalamus seem to be key players in pain modulation. An imbalance of pro- and anti-nociceptive mechanisms are assumed to cause chronic pain disorders, which are associated with spontaneous pain perception without physiologic scaffolding or exaggerated cortical activation in response to pain exposure. In contrast to recent investigations, the aim of the present study was to elucidate cortical activation of somatoform pain disorder patients during baseline condition. Scalp EEG, quantitative Fourier-spectral analyses and LORETA were employed to compare patient group (N = 15) to age- and sex-matched controls (N = 15) at rest. SI, SII, ACC, SMA, PFC, PPC, insular, amygdale and hippocampus displayed significant spectral power reductions within the beta band range (12-30 Hz). These results suggest decreased cortical baseline arousal in somatoform pain disorder patients. We finally conclude that obtained results may point to an altered baseline activity, maybe characteristic for chronic somatoform pain disorder.

  12. [Management of neuropathic pain]. (United States)

    Lozeron, P; Kubis, N


    Neuropathic pain is often underestimated and not adequately treated. The DN4 scale is very useful for its identification since it will benefit from pharmacological and non-pharmacological specific alternative care. The pathophysiological mechanisms involve the hyperexcitability of nociceptive pathways or decreased inhibitory descending controls that will be the target of pharmacological treatments. Frontline molecules are antidepressants (tricyclics and mixed serotonin and norepinephrine reuptake inhibitors) and antiepileptics (α2δ calcium channel inhibitors). However, these drugs will only have a partial efficacy on pain. The therapeutic strategy is based on reasonable goals, starting with a monotherapy adapted to the patient's symptoms and comorbidities and increased step by step. Patient compliance to contract is essential and requires clear and complete information. The impact on profession, social and family integration should rapidly be taken into account. In case of inefficiency, a change of the first-line treatment or an association could be considered. Some indications justify a specific therapy. Patients with resistant chronic pain should be sent to a specialized centre. New drugs are being studied and non-pharmacological support must be evaluated.

  13. Pain Intensity Moderates the Relationship Between Age and Pain Interference in Chronic Orofacial Pain Patients. (United States)

    Boggero, Ian A; Geiger, Paul J; Segerstrom, Suzanne C; Carlson, Charles R


    BACKGROUND/STUDY CONTEXT: Chronic pain is associated with increased interference in daily functioning that becomes more pronounced as pain intensity increases. Based on previous research showing that older adults maintain well-being in the face of pain as well as or better than their younger counterparts, the current study examined the interaction of age and pain intensity on interference in a sample of chronic orofacial pain patients. Data were obtained from the records of 508 chronic orofacial pain patients being seen for an initial evaluation from 2008 to 2012. Collected data included age (range: 18-78) and self-reported measures of pain intensity and pain interference. Bivariate correlations and regression models were used to assess for statistical interactions. Regression analyses revealed that pain intensity positively predicted pain interference (R(2) = .35, B = 10.40, SE = 0.62, t(507) = 16.70, p theories, including socioemotional selectivity theory, which posits that as people age, they become more motivated to maximize positive emotions and minimize negative ones. The results highlight the importance of studying the mechanisms older adults use to successfully cope with pain.

    Ritter, Alexander; Franz, Marcel; Puta, Christian; Dietrich, Caroline; Miltner, Wolfgang H. R.; Weiss, Thomas


    Previous functional magnetic resonance imaging (fMRI) studies in healthy controls (HC) and pain-free migraine patients found activations to pain-related words in brain regions known to be activated while subjects experience pain. The aim of the present study was to identify neural activations induced by pain-related words in a sample of chronic back pain (CBP) patients experiencing current chronic pain compared to HC. In particular, we were interested in how current pain influences brain acti...

    Pain management is an important aspect of burn management. We developed a routine pain monitoring system and pain management protocol for burn patients. The purpose of this study is to evaluate the effectiveness of our new pain management system. From May 2011 to November 2011, the prospective study was performed with 107 burn patients. We performed control group (n=58) data analysis and then developed the pain management protocol and monitoring system. Next, we applied our protocol to patients and performed protocol group (n=49) data analysis, and compared this to control group data. Data analysis was performed using the Numeric Rating Scale (NRS) of background pain and procedural pain, Clinician-Administered PTSD Scale (CAPS), Hamilton Depression Rating Scale (HDRS), State-Trait Anxiety Inventory Scale (STAIS), and Holmes and Rahe Stress Scale (HRSS). The NRS of background pain for the protocol group was significantly decreased compared to the control group (2.8±2.0 versus 3.9±1.9), and the NRS of procedural pain of the protocol group was significantly decreased compared to the control group (4.8±2.8 versus 3.7±2.5). CAPS and HDRS were decreased in the protocol group, but did not have statistical significance. STAIS and HRSS were decreased in the protocol group, but only the STAIS had statistical significance. Our new pain management system was effective in burn pain management. However, adequate pain management can only be accomplished by a continuous and thorough effort. Therefore, pain control protocol and pain monitoring systems need to be under constant revision and improvement using creative ideas and approaches. Copyright © 2012 Elsevier Ltd and ISBI.

  17. Pain management in cancer cervix

    Directory of Open Access Journals (Sweden)

    Palat Gayatri


    Full Text Available Cancer of the cervix uteri is a common cause of pain among women. On the physical realm, the cancer may cause somatic [soft tissue and bone], visceral and neuropathic pain [lumbosacral plexopathy]. Radiotherapy and chemotherapy may cause neuropathy too. Psychological, social and cultural factors modify the pain. Evaluation of the individual type of pain and a patient-centred approach are fundamental requirements for rational management. Disease modifying treatment like radiotherapy and chemotherapy must be considered when applicable. Pain control is usually achieved by the use of WHO three-step ladder, remembering that possible association of renal dysfunction would necessitate caution in the use of NSAIDs and opioids. Side effects must be anticipated, prevented when possible, and aggressively treated; nausea and vomiting may already be present, and constipation can worsen pain when there is a pelvic mass. Pain emergencies can be treated by quick titration with intravenous morphine bolus doses. Neuropathic pain may warrant the use of usual adjuvants, with particular reference to cortico-steroids and the NMDA antagonist, ketamine. In intractable pain, many neurolytic procedures are tried, but a solid evidence base to justify their use is lacking. Continuous epidural analgesia with local anaesthetic and opioid may be needed when drug therapy fails, and desperate situations may warrant interventions such as neurolysis. Such physical measures for pain relief must be combined with psychosocial support and adequate explanations to the patient and the family.

  18. Advanced dementia pain management protocols. (United States)

    Montoro-Lorite, Mercedes; Canalias-Reverter, Montserrat

    Pain management in advanced dementia is complex because of neurological deficits present in these patients, and nurses are directly responsible for providing interventions for the evaluation, management and relief of pain for people suffering from this health problem. In order to facilitate and help decision-makers, pain experts recommend the use of standardized protocols to guide pain management, but in Spain, comprehensive pain management protocols have not yet been developed for advanced dementia. This article reflects the need for an integrated management of pain in advanced dementia. From the review and analysis of the most current and relevant studies in the literature, we performed an approximation of the scales for the determination of pain in these patients, with the observational scale PAINAD being the most recommended for the hospital setting. In addition, we provide an overview for comprehensive management of pain in advanced dementia through the conceptual framework «a hierarchy of pain assessment techniques by McCaffery and Pasero» for the development and implementation of standardized protocols, including a four-phase cyclical process (evaluation, planning/performance, revaluation and recording), which can facilitate the correct management of pain in these patients.

  19. Integrative medicine for chronic pain (United States)

    Saha, Felix J.; Brüning, Alexander; Barcelona, Cyrus; Büssing, Arndt; Langhorst, Jost; Dobos, Gustav; Lauche, Romy; Cramer, Holger


    Abstract Introduction: Integrative medicine inpatient treatment has been shown to improve physical and mental health in patients with internal medicine conditions. The aim of this study was to investigate the effectiveness of a 2-week integrative medicine inpatient treatment in patients with chronic pain syndromes and the association of treatment success with patient-related process variables. Methods: Inpatients with chronic pain syndromes participating in a 2-week integrative medicine inpatient program were included. Patients’ pain intensity, pain disability, pain perception, quality of life, depression, and perceived stress were measured on admission, discharge, and 6 months after discharge. Likewise process variables including ability and will to change, emotional/rational disease acceptance, mindfulness, life and health satisfaction, and easiness of life were assessed. Results: A total of 310 inpatients (91% female, mean age 50.7 ± 12.4 year, 26.5% low back pain, and 22.9% fibromyalgia) were included. Using mixed linear models, significant improvements in pain intensity, pain disability, pain perception, quality of life, depression, and perceived stress were found (all P medicine inpatient treatment can benefit patients with chronic pain conditions. Functional improvements are associated with improved ability to change and implementation, disease acceptance, and satisfaction. PMID:27399133

    Full Text Available Marcela Romero-Reyes, James M Uyanik Orofacial and Head Pain Service, Department of Oral and Maxillofacial Pathology Radiology and Medicine, New York University College of Dentistry, New York, NY, USA Abstract: Some of the most prevalent and debilitating pain conditions arise from the structures innervated by the trigeminal system (head, face, masticatory musculature, temporomandibular joint and associated structures. Orofacial pain (OFP can arise from different regions and etiologies. Temporomandibular disorders (TMD are the most prevalent orofacial pain conditions for which patients seek treatment. Temporomandibular disorders include a number of clinical problems that involve the masticatory musculature, the temporomandibular joint (TMJ or both. Trigeminal neuropathic pain conditions can arise from injury secondary to dental procedures, infection, neoplasias, or disease or dysfunction of the peripheral and/or central nervous system. Neurovascular disorders, such as primary headaches, can present as chronic orofacial pain, such as in the case of facial migraine, where the pain is localized in the second and third division of the trigeminal nerve. Together, these disorders of the trigeminal system impact the quality of life of the sufferer dramatically. A multidisciplinary pain management approach should be considered for the optimal treatment of orofacial pain disorders including both non-pharmacological and pharmacological modalities.

  1. Current advances in orthodontic pain (United States)

    Long, Hu; Wang, Yan; Jian, Fan; Liao, Li-Na; Yang, Xin; Lai, Wen-Li


    Orthodontic pain is an inflammatory pain that is initiated by orthodontic force-induced vascular occlusion followed by a cascade of inflammatory responses, including vascular changes, the recruitment of inflammatory and immune cells, and the release of neurogenic and pro-inflammatory mediators. Ultimately, endogenous analgesic mechanisms check the inflammatory response and the sensation of pain subsides. The orthodontic pain signal, once received by periodontal sensory endings, reaches the sensory cortex for pain perception through three-order neurons: the trigeminal neuron at the trigeminal ganglia, the trigeminal nucleus caudalis at the medulla oblongata and the ventroposterior nucleus at the thalamus. Many brain areas participate in the emotion, cognition and memory of orthodontic pain, including the insular cortex, amygdala, hippocampus, locus coeruleus and hypothalamus. A built-in analgesic neural pathway—periaqueductal grey and dorsal raphe—has an important role in alleviating orthodontic pain. Currently, several treatment modalities have been applied for the relief of orthodontic pain, including pharmacological, mechanical and behavioural approaches and low-level laser therapy. The effectiveness of nonsteroidal anti-inflammatory drugs for pain relief has been validated, but its effects on tooth movement are controversial. However, more studies are needed to verify the effectiveness of other modalities. Furthermore, gene therapy is a novel, viable and promising modality for alleviating orthodontic pain in the future.

  3. Diagnosis and treatment of abnormal dental pain


    Fukuda, Ken-ichi


    Most dental pain is caused by an organic problem such as dental caries, periodontitis, pulpitis, or trauma. Diagnosis and treatment of these symptoms are relatively straightforward. However, patients often also complain of abnormal dental pain that has a non-dental origin, whose diagnosis is challenging. Such abnormal dental pain can be categorized on the basis of its cause as referred pain, neuromodulatory pain, and neuropathic pain. When it is difficult to diagnose a patient's dental pain, ...

  5. Pain and systemic lupus erythematosus

    Directory of Open Access Journals (Sweden)

    M. Di Franco


    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune disease characterized by heterogeneous clinical manifestations involving virtually the entire body. The pain in SLE can have different causes. The SLE classification criteria include mainly the musculoskeletal manifestations of pain, which are commonly reported as initial symptoms of SLE, such as arthralgia, arthritis and/or myalgia. Chronic widespread pain, which is typical of fibromyalgia (FM, is frequently associated with SLE. The aim of this review is to describe widespread pain and fatigue in SLE, and the association of SLE and FM. Although secondary FM is not correlated with the disease activity, it may interfere with the daily activities of SLE patients. Therefore it is necessary to identify its symptoms and treat them promptly to improve the quality of life of patients. In conclusion, it is essential to identify the origin of pain in SLE in order to avoid dangerous over-treatment in patients with co-existing widespread pain and FM.

  6. Practical approaches to spiritual pain. (United States)

    Brunjes, George B


    Spiritual pain/suffering is commonly experienced by persons with life-limiting illness and their families. Physical pain itself can be exacerbated by non-physical causes such as fear, anxiety, grief, unresolved guilt, depression and unmet spiritual meets. Likewise, the inability to manage physical pain well can be due to emotional and spiritual needs. This is why a holistic, interdisciplinary assessment of pain and suffering is required for each patient and family. The mind, body and spirit are understood in relationship to each other and, in those cases, in relationship to a deity or deities are important to understand. Cultural interpretations of pain and suffering may conflict with the goals of palliative care. Understanding the spiritual framework of the patient and family can help to assure that the physical and spiritual suffering of the patient can be eliminated to provide a peaceful death. Spiritual practices may help in the management of physical pain.

  7. Tai chi and chronic pain. (United States)

    Peng, Philip W H


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

  8. [Differential diagnosis of abdominal pain]. (United States)

    Frei, Pascal


    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain.

  10. Headache attributed to masticatory myofascial pain: impact on facial pain and pressure pain threshold. (United States)

    Costa, Y M; Porporatti, A L; Stuginski-Barbosa, J; Bonjardim, L R; Speciali, J G; Conti, P C R


    There is no clear evidence on how a headache attributed to temporomandibular disorder (TMD) can hinder the improvement of facial pain and masticatory muscle pain. The aim of this study was to measure the impact of a TMD-attributed headache on masticatory myofascial (MMF) pain management. The sample was comprised of adults with MMF pain measured according to the revised research diagnostic criteria for temporomandibular disorders (RDC/TMD) and additionally diagnosed with (Group 1, n = 17) or without (Group 2, n = 20) a TMD-attributed headache. Both groups received instructions on how to implement behavioural changes and use a stabilisation appliance for 5 months. The reported facial pain intensity (visual analogue scale--VAS) and pressure pain threshold (PPT--kgf cm(-2)) of the anterior temporalis, masseter and right forearm were measured at three assessment time points. Two-way anova was applied to the data, considering a 5% significance level. All groups had a reduction in their reported facial pain intensity (P 0·100). A TMD-attributed headache in patients with MMF pain does not negatively impact pain management, but does change the pattern for muscle pain improvement. © 2015 John Wiley & Sons Ltd.

  11. Effect of pain chronification and chronic pain on an endogenous pain modulation circuit in rats. (United States)

    Miranda, J; Lamana, S M S; Dias, E V; Athie, M; Parada, C A; Tambeli, C H


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

  12. Sharing the IT pain. (United States)

    Haugh, R


    Outsourcing info tech is too appealing a temptation for many hospitals to pass up. Information technology is costly, complex, prone to breakdowns and ever-changing. Many hospitals already outsource part of their IT operation, but there appears to be a trend toward outsourcing entire departments. Recently, a number of deals worth hundreds of millions of dollars were announced by some of the nation's largest systems and outsourcing companies. While outsourcing is the best alternative for certain operations, for others it may just be a trade-off between a short-term headache and long-term pain.

  13. [Acute anal pain]. (United States)

    Pittet, Olivier; Demartines, Nicolas; Hahnloser, Dieter


    Acute anal pain is a common proctological problem. A detailed history together with the clinical examination are crucial for the diagnosis. An acute perianal vein thrombosis can be successfully excised within the first 72 hours. Acute anal fissures are best treated conservatively using stool regulation and topical medications reducing the sphincter spasm. A chronic anal fissure needs surgery. Perianal abscesses can very often be incised and drained in local anesthesia. Proctalgia fugax and the levator ani syndrome are exclusion diagnoses and are treated symptomatically.

  14. Compartment syndrome without pain!

    LENUS (Irish Health Repository)

    O'Sullivan, M J


    We report the case of a young male patient who underwent intra-medullary nailing for a closed, displaced mid-shaft fracture of tibia and fibula. He was commenced on patient controlled analgesia post-operatively. A diagnosis of compartment syndrome in the patient\\'s leg was delayed because he did not exhibit a pain response. This ultimately resulted in a below-knee amputation of the patient\\'s leg. We caution against the use of patient controlled analgesia in any traumatised limb distal to the hip or the shoulder.

  17. Pain in Times of Stress


    AHMAD, Asma Hayati; ZAKARIA, Rahimah


    Stress modulates pain perception, resulting in either stress-induced analgesia or stress-induced hyperalgesia, as reported in both animal and human studies. The responses to stress include neural, endocrine, and behavioural changes, and built-in coping strategies are in place to address stressors. Peculiar to humans are additional factors that modulate pain that are experienced in times of stress, notably psychological factors that potentially influence the directionality of pain perception.

  18. Corporatization of pain medicine: implications for widening pain care disparities. (United States)

    Meghani, Salimah H


    The current health care system in the United States is structured in a way that ensures that more opportunity and resources flow to the wealthy and socially advantaged. The values intrinsic to the current profit-oriented culture are directly antithetical to the idea of equitable access. A large body of literature points to disparities in pain treatment and pain outcomes among vulnerable groups. These disparities range from the presence of disproportionately higher numbers and magnitude of risk factors for developing disabling pain, lack of access to primary care providers, analgesics and interventions, lack of referral to pain specialists, longer wait times to receive care, receipt of poor quality of pain care, and lack of geographical access to pharmacies that carry opioids. This article examines the manner in which the profit-oriented culture in medicine has directly and indirectly structured access to pain care, thereby widening pain treatment disparities among vulnerable groups. Specifically, the author argues that the corporatization of pain medicine amplifies disparities in pain outcomes in two ways: 1) directly through driving up the cost of pain care, rendering it inaccessible to the financially vulnerable; and 2) indirectly through an interface with corporate loss-aversion/risk management culture that draws upon irrelevant social characteristics, thus worsening disparities for certain populations. Thus, while financial vulnerability is the core reason for lack of access, it does not fully explain the implications of corporate microculture regarding access. The effect of corporatization on pain medicine must be conceptualized in terms of overt access to facilities, providers, pharmaceuticals, specialty services, and interventions, but also in terms of the indirect or covert effect of corporate culture in shaping clinical interactions and outcomes.

    This study aims to individualize the selection of drugs for neuropathic pain by examining the potential coupling of a given drug's mechanism of action with the patient's pain modulation pattern. The latter is assessed by the conditioned pain modulation (CPM) and temporal summation (TS) protocols. We hypothesized that patients with a malfunctioning pain modulation pattern, such as less efficient CPM, would benefit more from drugs augmenting descending inhibitory pain control than would patients with a normal modulation pattern of efficient CPM. Thirty patients with painful diabetic neuropathy received 1 week of placebo, 1 week of 30 mg/d duloxetine, and 4 weeks of 60 mg/d duloxetine. Pain modulation was assessed psychophysically, both before and at the end of treatment. Patient assessment of drug efficacy, assessed weekly, was the study's primary outcome. Baseline CPM was found to be correlated with duloxetine efficacy (r=0.628, P<.001, efficient CPM is marked negative), such that less efficient CPM predicted efficacious use of duloxetine. Regression analysis (R(2)=0.673; P=.012) showed that drug efficacy was predicted only by CPM (P=.001) and not by pretreatment pain levels, neuropathy severity, depression level, or patient assessment of improvement by placebo. Furthermore, beyond its predictive value, the treatment-induced improvement in CPM was correlated with drug efficacy (r=-0.411, P=.033). However, this improvement occurred only in patients with less efficient CPM (16.8±16.0 to -1.1±15.5, P<.050). No predictive role was found for TS. In conclusion, the coupling of CPM and duloxetine efficacy highlights the importance of pain pathophysiology in the clinical decision-making process. This evaluative approach promotes personalized pain therapy. Copyright © 2012 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

    van Assen, Tijmen; de Jager-Kievit, Jenneke W A J; Scheltinga, Marc R; Roumen, Rudi M H


    The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

  1. Pain-related guilt in low back pain. (United States)

    Serbic, Danijela; Pincus, Tamar


    Identifying mechanisms that mediate recovery is imperative to improve outcomes in low back pain (LBP). Qualitative studies suggest that guilt may be such a mechanism, but research on this concept is scarce, and reliable instruments to measure pain-related guilt are not available. We addressed this gap by developing and testing a Pain-related Guilt Scale (PGS) for people with LBP. Two samples of participants with LBP completed the scale and provided data on rates of depression, anxiety, pain intensity, and disability. Three factors were identified using exploratory factor analysis (n=137): "Social guilt," (4 items) relating to letting down family and friends; "Managing condition/pain guilt," (5 items) relating to failing to overcome and control pain; and "Verification of pain guilt," (3 items) relating to the absence of objective evidence and diagnosis. This factor structure was confirmed using confirmatory factor analysis (n=288), demonstrating an adequate to good fit with the data (AGFI=0.913, RMSEA=0.061). The PGS subscales positively correlated with depression, anxiety, pain intensity, and disability. After controlling for depression and anxiety the majority of relationships between the PGS subscales and disability and pain intensity remained significant, suggesting that guilt shared unique variance with disability and pain intensity independent of depression and anxiety. High levels of guilt were reported by over 40% of participants. The findings suggest that pain-related guilt is common and is associated with clinical outcomes. Prospective research is needed to examine the role of guilt as a predictor, moderator, and mediator of patients' outcomes.

  2. The efficacy and safety of low-dose radiotherapy on pain and functioning in patients with osteoarthritis: a systematic review. (United States)

    Minten, M J M; Mahler, E; den Broeder, A A; Leer, J W H; van den Ende, C H


    Low-dose radiotherapy (LD-RT) has been widely used for treatment of non-malignant disorders since its introduction and animal studies show anti-inflammatory effects in osteoarthritis (OA). However, the evidence for its effect in clinical practice remains unclear. Therefore, the aim of this study is to systematically summarise the literature on effectiveness of LD-RT on pain and functioning in patients with OA and its safety. Broad search terms were used to search PubMed, EMBASE and Web of Science. Primary inclusion criteria were osteoarthritis as indication, radiotherapy as intervention, written in English, German or Dutch and published since 1980. Study quality was assessed using the EPHPP Quality Assessment Tool for Quantitative Studies (scale: strong, moderate, weak). Seven studies were suitable for inclusion, all with retrospective uncontrolled observational design. Methodological quality of all studies was judged as weak. Most studies used 2-3 RT sessions per week for 2 weeks, some with booster session after 6 weeks. Generally, non-validated single-item measurement instruments were used to evaluate the effect of LD-RT on pain and function. Across the studies, in 25-90 and 29-71 % of the patients pain and functioning improved, respectively. Side effects were described in one study, none were reported. Our results show that there is insufficient evidence for efficacy or to confirm the safety of LD-RT in treatment of OA, due to absence of high-quality studies. Therefore, a well-designed, sham-controlled and blinded randomised trial, using validated outcome measures is warranted to demonstrate the value of LD-RT for OA in clinical practice.

  3. Managing neuropathic pain in dogs

    Full Text Available Disorders of the somatosensory system such as neuropathic pain are common in people with chronic neurologic and musculoskeletal diseases, yet these conditions remain an underappreciated morbidity in our veterinary patients. This is likely because assessment of neuropathic pain in people relies heavily on self-reporting, something our veterinary patients are not able to do. The development of neuropathic pain is a complex phenomenon, and concepts related to it are frequently not addressed in the standard veterinary medical curriculum such that veterinarians may not recognize this as a potential problem in patients. The goals of this review are to discuss basic concepts in the pathophysiology of neuropathic pain, provide definitions for common clinical terms used in association with the condition, and discuss available medical treatment options for dogs with neuropathic pain. The development of neuropathic pain involves key mechanisms such as ectopic afferent nerve activity, peripheral sensitization, central sensitization, impaired inhibitory modulation, and activation of microglia. Treatments aimed at reducing neuropathic pain are targeted at one or more of these mechanisms. Several drugs are commonly used in the veterinary clinical setting to treat neuropathic pain. These include gabapentin, pregabalin, amantadine, and amitriptyline. Proposed mechanisms of action for each drug, and known pharmacokinetic profiles in dogs are discussed. Strong evidence exists in the human literature for the utility of most of these treatments, but clinical veterinary-specific literature is currently limited. Future studies should focus on objective methods to document neuropathic pain and monitor response to therapy in our veterinary patients.

  4. Pain management in lung cancer. (United States)

    Nurwidya, Fariz; Syahruddin, Elisna; Yunus, Faisal


    Lung cancer is the leading cause of cancer-related mortality worldwide. Not only burdened by the limited overall survival, lung cancer patient also suffer from various symptoms, such as pain, that implicated in the quality of life. Cancer pain is a complicated and transiently dynamic symptom that results from multiple mechanisms. This review will describe the pathophysiology of cancer pain and general approach in managing a patient with lung cancer pain. The use of opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and adjuvant analgesia, as part of the pharmacology therapy along with interventional strategy, will also be discussed.

  5. Pain Associated With Hysteroscopic Sterilization (United States)

    Levy, Jenna; Childers, Meredith E.


    Background and Objectives: The safety and efficacy of female hysteroscopic sterilization using the Essure system has been well documented. Given the marked differences in the execution of hysteroscopic and laparoscopic sterilization, the objective of this study was to assess the experience of pain postprocedure between the 2. Secondary end-points included postoperative pain medication, time to return to normal activities, postprocedure bleeding, and patient satisfaction. Methods: Twenty cases each of laparoscopic sterilization (LS) and hysteroscopic sterilization (HS) were performed. Patients were surveyed regarding their experience of pain immediately postoperatively, 1 week, and 4 weeks post-procedure. Results: The average pain score immediately postprocedure was significantly lower among HS patients than among LS patients (t=−8.17, P<.0001). One-week post-procedure, none of the patients in the HS group reported any pain, while the average pain score among the LS patients was 2.65 (t =−9.67, P<.0001). Four weeks post-procedure, women in the HS group continued to report no pain, 35% of the LS group continued to report some pain (t=−3.04, P=.004). Conclusions: Hysteroscopic sterilization offers a minimally invasive, less painful, equally efficacious modality for sterilization than laparoscopic sterilization and should be available to all women seeking permanent birth control.

  6. The Cannabinoid System and Pain (United States)

    Woodhams, Stephen G.; Chapman, Victoria; Finn, David P.; Hohmann, Andrea G.; Neugebauer, Volker


    Chronic pain states are highly prevalent and yet poorly controlled by currently available analgesics, representing an enormous clinical, societal, and economic burden. Existing pain medications have significant limitations and adverse effects including tolerance, dependence, gastrointestinal dysfunction, cognitive impairment, and a narrow therapeutic window, making the search for novel analgesics ever more important. In this article, we review the role of an important endogenous pain control system, the endocannabinoid (EC) system, in the sensory, emotional, and cognitive aspects of pain. Herein, we briefly cover the discovery of the EC system and its role in pain processing pathways, before concentrating on three areas of current major interest in EC pain research; 1. Pharmacological enhancement of endocannabinoid activity (via blockade of EC metabolism or allosteric modulation of CB1 receptors); 2. The EC System and stress-induced modulation of pain; and 3. The EC system & medial prefrontal cortex (mPFC) dysfunction in pain states. Whilst we focus predominantly on the preclinical data, we also include extensive discussion of recent clinical failures of endocannabinoid-related therapies, the future potential of these approaches, and important directions for future research on the EC system and pain.

  7. Optimal management of orthodontic pain. (United States)

    Topolski, Francielle; Moro, Alexandre; Correr, Gisele Maria; Schimim, Sasha Cristina


    Pain is an undesirable side effect of orthodontic tooth movement, which causes many patients to give up orthodontic treatment or avoid it altogether. The aim of this study was to investigate, through an analysis of the scientific literature, the best method for managing orthodontic pain. The methodological aspects involved careful definition of keywords and diligent search in databases of scientific articles published in the English language, without any restriction of publication date. We recovered 1281 articles. After the filtering and classification of these articles, 56 randomized clinical trials were selected. Of these, 19 evaluated the effects of different types of drugs for the control of orthodontic pain, 16 evaluated the effects of low-level laser therapy on orthodontic pain, and 21 evaluated other methods of pain control. Drugs reported as effective in orthodontic pain control included ibuprofen, paracetamol, naproxen sodium, aspirin, etoricoxib, meloxicam, piroxicam, and tenoxicam. Most studies report favorable outcomes in terms of alleviation of orthodontic pain with the use of low-level laser therapy. Nevertheless, we noticed that there is no consensus, both for the drug and for laser therapy, on the doses and clinical protocols most appropriate for orthodontic pain management. Alternative methods for orthodontic pain control can also broaden the clinician's range of options in the search for better patient care.

  8. Rehabilitation Medicine Approaches to Pain Management. (United States)

    Cheville, Andrea L; Smith, Sean R; Basford, Jeffrey R


    Rehabilitation medicine offers strategies that reduce musculoskeletal pain, targeted approaches to alleviate movement-related pain, and interventions to optimize patients' function despite the persistence of pain. These approaches fall into four categories: modulating nociception, stabilizing and unloading painful structures, influencing pain perception, and alleviating soft tissue musculotendinous pain. Incorporating these interventions into individualized, comprehensive pain management programs offers the potential to empower patients and limit pain associated with mobility and required daily activities. Rehabilitative approach may be particularly helpful for patients with refractory movement-associated pain and functional vulnerability, and for those who do not wish for, or cannot, tolerate pharmacoanalgesia.

  10. Helicobacter pylori infection and nonmalignant diseases. (United States)

    Sjomina, Olga; Heluwaert, Frederic; Moussata, Driffa; Leja, Marcis


    A substantial decrease in Helicobacter pylori-associated peptic ulcer disease has been observed during the last decades. Drug-related ulcers as well as idiopathic ulcers are becoming predominant and are more refractory to treatment; however, H. pylori infection still plays an important role in ulcer bleeding and recurrence after therapy. The effect of H. pylori eradication upon functional dyspepsia symptoms has been reviewed in this article and generally confirms the results of previous meta-analyses. Additional evidence suggests a lack of impact upon the quality of life, in spite of improvement in symptoms. The association of H. pylori with gastroesophageal reflux disease and Barrett's esophagus remains controversial with a majority of published studies showing a negative association. Furthermore, a strong inverse relationship between the presence of H. pylori and the esophageal eosinophilia was also reported. Several studies and a review addressed the role of H. pylori in autoimmune gastritis and pernicious anemia. The association of the above still remains controversial. Finally, the necessity of routine endoscopy and H. pylori eradication before bariatric surgery is discussed. Several studies suggest the rationale of preoperative upper endoscopy and H. pylori eradication prior to surgery. However, the prevalence of H. pylori infection prior to surgery in these studies generally reflects the overall prevalence of the infection in the particular geographic area. In addition, results on the role of H. pylori in developing postoperative complications remain controversial. © 2017 John Wiley & Sons Ltd.

  11. Helicobacter pylori and non-malignant diseases. (United States)

    Matysiak-Budnik, Tamara; Laszewicz, Wiktor; Lamarque, Dominique; Chaussade, Stanislas


    The prevalence of Helicobacter pylori-associated peptic ulcers, in particular duodenal ulcers, is decreasing following decreasing prevalence of H. pylori infection, while the frequency of non-steroidal anti-inflammatory drugs (NSAIDs)-induced and H. pylori-negative idiopathic ulcers is increasing. The incidence of bleeding ulcers has been stable during the last decades. Several putative H. pylori virulence genes, i.e., cag, vacA, babA, or dupA, as well as host-related genetic factors like IL-1beta and TNFalpha-gene polymorphism, have been proposed as risk factors for duodenal ulcer. H. pylori eradication may prevent NSAID complications, in particular, when it is performed before introduction of NSAIDs. There is a complex association between H. pylori and gastroesophageal reflux disease (GERD), and the impact of H. pylori eradication on the appearance of GERD symptoms depends on various host- and bacteria-related factors. Eradication of H. pylori in GERD is recommended in patients before instauration of a long-term PPI treatment to prevent the development of gastric atrophy. A small proportion (10%) of non-ulcer dyspepsia cases may be attributed to H. pylori and may benefit from eradication treatment. A test-and-treat strategy is more cost-effective than prompt endoscopy in the initial management of dyspepsia.

  12. Addiction and Pain Medicine

    Directory of Open Access Journals (Sweden)

    Douglas Gourlay


    Full Text Available The adequate cotreatment of chronic pain and addiction disorders is a complex and challenging problem for health care professionals. There is great potential for cannabinoids in the treatment of pain; however, the increasing prevalence of recreational cannabis use has led to a considerable increase in the number of people seeking treatment for cannabis use disorders. Evidence that cannabis abuse liability is higher than previously thought suggests that individuals with a history of substance abuse may be at an increased risk after taking cannabinoids, even for medicinal purposes. Smoked cannabis is significantly more reinforcing than other cannabinoid administration methods. In addition, it is clear that the smoked route of cannabis delivery is associated with a number of adverse health consequences. Thus, there is a need for pharmaceutical-grade products of known purity and concentration using delivery systems optimized for safety. Another factor that needs to be considered when assessing the practicality of prescribing medicinal cannabinoids is the difficulty in differentiating illicit from prescribed cannabinoids in urine drug testing. Overall, a thorough assessment of the risk/benefit profile of cannabinoids as they relate to a patient’s substance abuse history is suggested.

  15. Evaluation of pain management interventions for neonatal circumcision pain. (United States)

    Joyce, B A; Keck, J F; Gerkensmeyer, J


    The purpose of the study was to determine the efficacy of music and eutectic mixture of local anesthetics (EMLA) on pain responses of neonates undergoing circumcision. A randomized, double-blind experimental design was used with 23 neonates. Pain response was measured using an observational pain intensity rating scale and the physiologic parameters of heart rate, respiratory rate, oxygen saturation levels, salivary cortisol levels, and length of cry. Each infant's state was examined for a potential contribution to the pain response. Infant state, salivary cortisol levels, and respiratory rates were not significant. Pain ratings had considerable variability for all treatment conditions, but both single treatment groups had less pain by the end of the procedure. The heart rate was significantly lower for the EMLA group and remained stable for the music group. Oxygen saturation differences were statistically significant for the music group (P =.02) and approached significance for the EMLA group. Preliminary support was provided for the efficacy of EMLA and music to contribute to the pain relief of neonates undergoing circumcision. Further study is warranted. Neonates deserve interventions that will provide them with a less painful start in life.

  17. Pain and pain tolerance in professional ballet dancers. (United States)

    Tajet-Foxell, B; Rose, F D


    Pain experience in sport had been the subject of increasing research in recent years. While sports professionals have generally been found to have higher pain thresholds than control subjects the reasons for this are not entirely clear. The present study seeks to investigate one possible explanatory factor, the importance of the popular image of the physical activity and of the self-image of its participants, by examining pain experience in professional ballet dancers. Like sports professionals, dancers were found to have higher pain and pain tolerance thresholds than age matched controls in the Cold Pressor Test. However, they also reported a more acute experience of the sensory aspects of the pain. Explanations of this apparent paradox are discussed both in terms of the neuroticism scores of the two groups and in terms of the dancers' greater experience of pain and its relationship with physical activity. The results illustrated the importance of using multidimensional measures of pain in this type of investigation. PMID:7788215

  18. [The pain-emotion: Advocating pain as an emotion]. (United States)

    Fonseca Das Neves, J; Sule, N; Serra, E


    Pain is a common experience, both physical and emotional. However we often feel powerless with our patients suffering pain. This paper aims to give a new heuristic and psychological understanding of pain. According to new theories, recent researches as well as different points of view, we form an analogy between pain and emotion. Throughout historical considerations pain has always been perceived through theories and beliefs, changing its definition. This is also the case for emotion. Could they be two ways of expressing a single phenomenon? First, we must clarify the definition of emotion. In past, emotion was considered as a multiple-conditioned notion. To be considered as an emotion the pain had to fill numerous features, which differ according to the scientific opinions. The emotion may be considered as a physical expression or perceived only as the consequences of a real emotion, i.e., the subjective feeling. We propose as a way of thinking that emotion brings together these two concepts. We support a flexible vision of emotion. To investigate the field of the emotion different mental steps may be thought of: we should conceive of the emotion as a stimulus, as an emotional evaluation and as a tendency to action, which becomes an emotional response. These steps are colored by subjective feelings. It can be summarized in three levels: the situation decoding (1), the response organization (2) and the effectiveness of the response (3). Second pain can be considered as a complex notion involving personal and subjective feelings. We can use multidimensional patterns and consider emotion with its multiple features: the generating mechanisms, the pain perception, the pain behavior and the environment. Each stage can be divided in different ways. Hence pain treatment could be approached as an emotional treatment. Indeed, we can make a link between generating mechanisms and emotion situation decoding, between pain perception and emotion situation decoding and response

  19. [Pain therapy in pediatric oncology: pain experience, drugs and pharmacokinetics]. (United States)

    Mertens, Rolf


    Paediatric cancer patients often experience fear and pain from the disease but also in connection with the necessary diagnostic and therapeutic procedures. The treatment of pain is a priority for all patients, especially for critically ill children because of their vulnerability and limited understanding. The experience of pain is always subjective and depends on the age, the pain experience and the environment.In contrast to adults, it is often difficult to detect character of pain, pain intensity and pain localization in very young patients. Diagnostic and therapeutic procedures are performed in analgosedation for a given drug scheme by a pediatrician experienced in intensive care.In addition, a local anesthetic for an access system/lumbar punctures in the form of EMLA® patch is to be carried out. A rapid and effective treatment of pain and appropriate analgesia can prevent patients from being traumatized.For severe pain, malignancy- or chemotherapy-induced (eg. mucositis WHO grade 3 and 4) initial use of strong opiates is recommended instead of climbing the WHO ladder. For strong opiates, there is no maximum dose, as long as a dose increase leads to clinically observable increase in analgesia, without severe side effects. Patient-controlled analgesia with morphine as continuous subcutaneous or intravenous infusions and the possibility of a bolus injection is suited for children aged 6 years. A measurement of O2-saturation is essential during this infusion. Prophylactic approaches also must be used consistently in regard to the acute side effect of opiate treatment. Good experience, we have also made a non-drug therapy, e.g. personnel/physical affection, cuddling, massage, etc.The choice of analgesia depends on the nature and cause of pain. In neuropathic pain or phantom pain coanalgetics should be used to effectively treat pain in young patients. Different analgesic treatment approaches of the appropriate indications and adverse effects are presented. A

    completed the PDQ (RA: 3,826, PsA: 1,180, SpA: 1,093). 52% of all patients and 63% of PDQ-completers had VAS pain score ≥ 30 mm. The distribution of the PDQ classification-groups (18) were; RA: 56%/24%/20%. PsA: 45%/ 27%/ 28%. SpA: 55% / 24%/ 21%. More patients with PsA had PDQ score >18....... The objectives were to quantify and characterize pain phenotypes (non-neuropathic vs. neuropathic features) among Danish arthritis patients using the PDQ, and to assess the association with on-going inflammation. METHODS: The PDQ was included onto the DANBIO touch screens at 22 departments of Rheumatology......28-CRP and VAS pain but not with indicators of peripheral inflammation (CRP and SJC). Thus, pain classification by PDQ may assist in mechanism-based pain treatment....
