Abstract
There is some evidence for attentional biases in individuals with chronic pain (CP). Cultural and linguistic differences might affect the manifestation of these processes across populations. However, such attentional biases have not been explored in the Arabic-speaking population. The current study investigated these attentional biases and possible associations with resilience. Two matched groups of Arabic-speaking participants with (58) and without (58) CP were recruited from Jordan and the United Kingdom. They completed emotionally modified versions of the Posner cueing and Stroop tasks, alongside questionnaires. Significant group differences were found for the Posner task, with the CP group exhibiting disengagement revealed by the inhibition of return (IOR) effect for sensory pain-related cues compared to delayed disengagement for the other cue types. The control group showed IOR across cue types. No group differences were found on the Stroop task. The CP group had lower resilience scores than healthy controls, and resilience moderated performance on the Posner task. The study provides preliminary evidence about the attentional processes in the Arabic population; the speed of disengagement is affected in the CP group with early disengagement for sensory pain-related information compared to affect pain and neutral stimuli. Furthermore, resilience levels in the CP and control group moderated the performance on the Posner task, suggesting that it influences attentional allocation. This study can help in understanding how the phenomenon of attention bias intertwines with the cultural and linguistic factors. Future research should further explore attentional dynamics across different time points in this population and the modulatory effect of resilience.

Exploring chronic pain related attentional experiences, distress and coping strategies among Arabic-speaking individuals in Jordan and the United Kingdom. Front Psychol 2023; 14:1268179. [PMID: 37849474 PMCID: PMC10577280 DOI: 10.3389/fpsyg.2023.1268179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 09/15/2023] [Indexed: 10/19/2023] Open
Abstract
Introduction The lived experiences of chronic pain (CP) among Arabic-speaking populations remain underexplored. A better understanding of these experiences and their associations with attention difficulties, coping mechanisms, and treatment options could lead to improved support for this group. Methods This qualitative study utilised a descriptive design and involved one-to-one interviews with 51 participants with CP who had just completed two attention tasks. Interviews were conducted using a semi-structured topic guide, transcribed verbatim and translated from Arabic to English before agreeing on the coding framework. Themes and subthemes were extracted using a framework analysis approach. Results The study identified six main themes: Factors contributing towards developing or exacerbating CP, the impact of CP on psychosocial functions, including attention, the perceived role of social support, coping strategies for managing CP, perceptions about available treatments and recommendations for interventions. Discussion CP significantly impacts individuals' physical and psychosocial functions, and it is reciprocally associated with attentional difficulties. Despite using various approaches to manage their CP, none of the participants used psychological interventions or counselling. Understanding the diverse impacts of CP and the coping strategies employed to develop culturally sensitive interventions, review current related policies, and improve healthcare services is crucial to managing CP among this population.

Abstract
Cancer pain remains a significant problem worldwide. It is often undertreated and presents in about half of cancer patients. Although several guidelines and pharmacological interventions for cancer pain management (CPM) exist, inadequate assessment and undertreatment of cancer pain are well-documented globally, especially in developing countries, including Libya. Perceptions, cultural and religious beliefs of healthcare professionals (HCP), patients, and caregivers about cancer pain and opioids are reported as barriers to CPM globally. This qualitative descriptive study aimed to explore Libyan HCPs', patients', and caregivers' views and religious beliefs about CPM and involved semi-structured interviews with 36 participants: 18 Libyan cancer patients, 6 caregivers, and 12 Libyan HCPs. Thematic analysis was used to analyse the data. Patients, caregivers, and newly qualified HCPs were concerned about poor tolerance and drug addiction. HCPs perceived a lack of policies and guidelines, pain rating scales, and professional education and training as CPM barriers. Some patients were unable to pay for medicines if they faced financial difficulties. Instead, patients and caregivers emphasised religious and cultural beliefs for managing cancer pain, including the use of the Qur'an and cautery. Our results suggest that religious and cultural beliefs, lack of knowledge and training in CPM among HCPs, and economic and Libyan healthcare system-related factors negatively affect CPM in Libya.

Abstract
Introduction The World Health Organization recognizes chronic pain as a global public health concern; however, there is a bias towards research conducted in relatively affluent nations. There is a dearth of large-scale epidemiological studies in Nepal using rigorously validated, cross-culturally adapted instruments. Objectives The aim of this study was to examine the prevalence of both chronic pain and chronic pain of predominantly neuropathic origin and their associations with a range of sociodemographic and psychosocial characteristics. Methods We conducted a cross-sectional study of adults (≥18 years) in all households in Ranipani, Baluwa Village Development Committee, Nepal. All adults (n = 887) were approached, and those consenting, who met the inclusion criteria (n = 520, 58.6%), participated. Questionnaires validated in Nepali were used to examine several constructs: demographics; chronic pain; neuropathic pain; pain catastrophizing; resilience, pain intensity; pain interference; sleep disturbance; and depression. Results The point prevalence of chronic pain was 53.3% (n = 277). The point prevalence of chronic pain of predominantly neuropathic origin was 12.7% (n = 66). Chronic pain was associated with female gender, older age, and manual labour occupations. Using standardized scoring techniques, compared with available population estimates from other countries, those with chronic pain were associated with lower pain intensity and resilience scores and higher pain catastrophizing, pain interference, and depression scores. Conclusion These findings are broadly comparable to epidemiological studies from other countries, and these indicate areas for targeting interventions (eg, occupational and mental health). For comparison, more data are needed, from larger population samples in this region.

Prevalence of pain and its treatment among older adults in India: a nationally representative population-based study. Pain 2023; 164:336-348. [PMID: 36638306 DOI: 10.1097/j.pain.0000000000002705] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 05/25/2022] [Indexed: 02/06/2023]
Abstract
ABSTRACT There were no estimates of the prevalence of pain and its treatment in the older population of India obtained from face-to-face interviews with a nationally representative sample. We addressed this evidence gap by using data on 63,931 individuals aged 45 years and older from the 2017/2018 Longitudinal Ageing Study in India. We identified pain from an affirmative response to the question: Are you often troubled by pain? We also identified those who reported pain that limited usual activities and who received treatment for pain. We estimated age- and sex-adjusted prevalence of pain, pain limiting usual activity and treatment, and compared these estimates across states and sociodemographic groups. We used a multivariable probit model to estimate full adjusted differences in the probability of each outcome across states and sociodemographic groups. We estimated that 36.6% (95% confidence interval [CI]: 35.3-37.8) of older adults in India were often troubled by pain and 25.2% (95% CI: 24.2-26.1) experienced pain limiting usual activity. We estimated that 73.3% (95% CI: 71.9-74.6) of those often troubled by pain and 76.4% (95% CI: 74.9-78.0) of those with pain that limited usual activity received treatment. There was large variation in each outcome across states. Fully adjusted prevalence of pain and pain limiting usual activity were higher among individuals who were female, older, less educated, rural residents, and poorer. Prevalence of treatment among those troubled by pain was lower among socially disadvantaged groups.

Abstract
Background Chronic pain (CP) prevalence estimates addressing a wide phenotype are still quite fragmented and may vary widely due to the lack of standardized tools of investigation. There is an urgent need to update general population CP estimates. Methods For this purpose, the Brief Five-item Chronic Pain Questionnaire was developed through experts’ consultations for design and content validity assessment; literature analysis of measures used to investigate CP for general population surveys; understandability evaluation through a survey on a convenience sample of affected and non-affected individuals; reliability assessment by means of two double-wave online surveys carried out by the Italian Twin Registry; criterion and construct validity assessment through the third wave of the 2019 European Health Interview Survey (Ehis). Results Key dimensions were defined to describe CP main aspects from a public health perspective. Literature analysis showed that validated questionnaires were rarely used to address important public health CP aspects. Understandability of the measure was good. Test-retest analyses showed adequate reliability of the measure: k values were at least “moderate” with highest values regarding CP “occurrence” and “intensity”. Correlations of CP with well-known comorbidities (cancer, depression), and specific traits (age, education) as well as of CP and its intensity with “physical pain occurrence and intensity” detected in the Ehis 2019, confirmed, respectively, a good construct and criterion validity. Construct validity was also evaluated through the correlation between “perceived treatment effectiveness” and “interference of pain in daily life activities” as recorded in the Ehis 2019. Conclusion The designed questionnaire is a brief self-administered measure, particularly suitable to detect persistent states of pain and related intensity in large-scale general population surveys by means of a first filtering item followed by four further items. It is, in fact, designed to detect CP possible underlying causes/triggers, drugs/treatments taking and frequency, and self-perceived effectiveness among CP sufferers. Further validation of the measure in different social and cultural contexts is desirable.

Chronic Stress and Gonadectomy Affect the Expression of Cx37, Cx40 and Cx43 in the Spinal Cord. Life (Basel) 2021; 11:life11121330.

Abstract
The study aimed to determine whether the exposure to chronic stress and/or performance of gonadectomy might lead to disturbance in the expression of connexin (Cx) 37, 40 and 43 in the spinal cord (SC), as a potential explanation for sex differences in stress-related chronic pain conditions. After the rats were sham-operated or gonadectomized, three 10-day sessions of sham or chronic stress were applied. Immunohistochemistry and transmission electron microscopy (TEM) were used to examine Cx localization and expression in the SC. The gonadectomy resulted in an increase of Cx37 expression in the dorsal horn (DH) of the female rats, but chronic stress suppressed the effects of castration. In male rats, only the combined effects of castration and chronic stress increased Cx37 expression. The influence of chronic stress on the DH Cx40 expression was inversely evident after the castration: increased in the ovariectomized female rats, while decreased in the orchidectomized male rats. We did not find any effect of chronic stress and castration, alone or together, on Cx43 expression in the DH, but the percentage of Cx43 overlapping the astrocyte marker glial fibrillary acidic protein (gfap) increased in the male stressed group after the castration. In conclusion, the association of the chronic stress with sex hormone depletion results in disturbances of the SC Cx expression and might be a possible mechanism of disturbed pain perception after chronic stress exposure.

The prevalence of chronic pain in young adults: a systematic review and meta-analysis. Pain 2021; 163:e972-e984. [PMID: 34817439 DOI: 10.1097/j.pain.0000000000002541] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 11/15/2021] [Indexed: 11/26/2022]
Abstract
ABSTRACT Prior systematic reviews have summarized the prevalence and impact of chronic pain in "average" pediatric (i.e., school-age) and adult (i.e., middle-age) age groups. To our knowledge, this is the first study to describe the prevalence of chronic pain in the subgroup of individuals that fall in between established boundaries of "childhood" and "adulthood" - known as young adulthood. The goal of this research was to meta-analyze prevalence data on pain in young adults based on available data published between 2008 and 2020. Searches were identified with MEDLINE, Embase, and PsycINFO. We included general population and university-based studies presenting prevalence estimates of chronic pain (pain lasting ≥3 months) in young adults. We identified 43 articles providing prevalence estimates across a combined population of 97,437 young adult respondents (age range: 15-34), with studies undertaken in 22 countries. Available data allowed for stratification of prevalence according to pain condition. The overall pooled random-effect prevalence rate of chronic pain in young adults was 11.6%, suggesting that 1 in every 9 young adults experience chronic pain worldwide. Prevalence rates varied considerably according to pain condition. Estimates did not vary according to sex, geographic location, and several study methodological characteristics (i.e., population type, sampling area, sampling year, investigation period, assessment method). Overall, young adult chronic pain is common and should be recognized as a major public health concern. Considering the difficulties young adults face accessing adult healthcare, greater attention is needed to develop transition programs and evidence-based treatments tailored to the unique needs of this age group.

Abstract
Objectives: Diagnosis of neuropathic pain is challenging. Recently, scientists developed multiple questionnaires to expedite this diagnosis including the Self-completed Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS), Douleur Neuropathique 4 questionnaire (DN4), and Neuropathic Pain Questionnaire–Short Form (NPQ-SF). Materials and Methods: We conducted a prospective cohort study to compare the psychometric characteristics and accuracy of the three questionnaires. We assessed reliability with the Cronbach's α reliability coefficient and inter-item correlations, and validity with receiver operating characteristic (ROC) and correlation analyses. We assessed agreement between the diagnosis of the questionnaires and the reference clinical diagnosis using Cohen's kappa coefficient. Results: 188 patients were analyzed: 141 (75%) had “definite neuropathic” and 47 (25%) had “nonneuropathic” pain. The NPQ-SF and S-LANSS questionnaires demonstrated acceptable reliability with Cronbach's α coefficient values of 0.54 (95% CI: 0.41–0.64) and 0.65, (95%CI: 0.57–0.72), respectively. The DN4 questionnaire demonstrated high reliability with Cronbach's α coefficient of 0.74 (95%CI: 0.68–0.79). The NPQ-SF, DN4, and S-LANSS questionnaires demonstrated “excellent” diagnostic ability with an area under the ROC curve of 0.82 (95% CI: 0.75–0.89), 0.89 (95% CI: 0.83–0.95), and 0.83 (95% CI: 0.75–0.90), respectively. Based on their optimal cutoff values, the DN4 had the highest sensitivity and lowest specificity in discriminating between neuropathic and nonneuropathic patients, while the S-LANSS had the lowest sensitivity and highest specificity. Conclusion: Both NPQ-SF and S-LANSS demonstrated acceptable reliability, while DN4 demonstrated high reliability. All three demonstrated excellent diagnostic validities; however, it is important to consider the sensitivity and specificity of each.

Abstract
Whole-body vibration (WBV), which is widely used as a type of exercise, involves the use of vibratory stimuli and it is used for rehabilitation and sports performance programmes. This study aimed to investigate the effect of WBV treatment in a chronic pain model after 10 WBV sessions. An animal model (chronic pain) was applied in 60 male Wistar rats (±180 g, 12 weeks old) and the animals were treated with low intensity exercise (treadmill), WBV (vibrating platform), and a combined treatment involving both. The controls on the platform were set to a frequency of 42 Hz with 2 mm peak-to-peak displacement, g ≈ 7, in a spiral mode. Before and after the vibration exposure, sensitivity was determined. Aβ-fibers-mediated mechanical sensitivity thresholds (touch-pressure) were measured using a pressure meter. C-fibers-mediated thermal perception thresholds (hot pain) were measured with a hot plate. After each session, WBV influenced the discharge of skin touch-pressure receptors, reducing mechanical sensitivity in the WBV groups (P < 0.05). Comparing the conditions "before vs. after", thermal perception thresholds (hot pain) started to decrease significantly after the third WBV session (P < 0.05). WBV decreases mechanical hyperalgesia after all sessions and thermal sensitivity after the third session with the use of WBV.

Chronic stress has various effects on organisms and is sex-specific. The aim of the study was to describe the expression of synapse strengthening protein, dendrin, in the spinal cord (SC) and the dependence of its expression on chronic stress and sex hormones. Thirteen-month-old female and male rats were castrated (ovariectomy [F-OVX] or orchidectomy [M-ORX]) or sham-operated (F-SH or M-SH), respectively. At age 15 months, three 10-day-sessions of sham stress (control, C) or chronic stress (S) were conducted. Dendrin expression was present in the thoracic SC segments and the dorsal root ganglia (DRG). In the SC, dendrin expression was prominent in superficial laminae of the dorsal horn and lamina X (central canal). The M-ORX-S group had the highest dendrin expression in the dorsal horn, being significantly higher than the M-ORX-C or M-SH-S groups (P < 0.05). Dendrin expression was significantly higher in the F-SH-S group than the F-SH-C group (P < 0.05), as well as in the F-SH-S than the M-SH-S (P < 0.05). Co-localization with the α-d-galactosyl-specific isolectin B4 (IB4) in central projections of the DRG neurons in the dorsal horn of the SC was 7.43 ± 3.36%, while with the calcitonin gene-related peptide (CGRP) was 8.47 ± 4.45%. Localization of dendrin was observed in soma and nuclei of neurons in the dorsal horn. Dendrin expression in pain-processing areas of the SC, the DRG neurons and their peripheral projections suggest possible roles in pain perception and modulation. Stress-induced increase in dendrin expression and its dependence on sex hormones may partially explain sex-specific pain hypersensitivity induced by stress.

Abstract
To increase our understanding of chronic pain in clinical and research contexts, an assessment of its dimensions using reliable and valid self-reported pain measures is imperative. However, well-validated Arabic chronic pain assessment scales are lacking. The Chronic Pain Grade (CPG) scale has been used worldwide, yet an Arabic version of the CPG scale has not yet been validated. Thus, we conducted this study to demonstrate the psychometric properties, including reliability, convergent validity, and construct validity of the Arabic CPG scale. A cross-sectional study was conducted in two hospitals in Saudi Arabia. Data were collected from a convenience sample of 233 chronic pain patients. The confirmatory factor analysis showed an excellent fit with the factor structure of the CPG scale and, thus, supported construct validity. The two identified subscales were pain intensity and pain disability. Convergent validity was supported by having significant correlations between the short-form McGill Pain Questionnaire and CPG subscales. Internal consistency reliability was demonstrated, as Cronbach's α was 0.916 for pain intensity and 0.815 for pain disability. This study provides evidence that the Arabic CPG scale is a reliable and valid measure of chronic pain dimensions, including pain intensity, and pain-related disability. This Arabic version of the CPG scale has the potential to expand research and clinical assessment in the Arab world. Future studies are required for further validation.

Abstract
Pain is a multidimensional experience mediated by distributed neural networks in the brain. To study this phenomenon, EEGs were collected from 20 subjects with chronic lumbar radiculopathy, 20 age and gender matched healthy subjects, and 17 subjects with chronic lumbar pain scheduled to receive an implanted spinal cord stimulator. Analysis of power spectral density, coherence, and phase-amplitude coupling using conventional statistics showed that there were no significant differences between the radiculopathy and control groups after correcting for multiple comparisons. However, analysis of transient spectral events showed that there were differences between these two groups in terms of the number, power, and frequency-span of events in a low gamma band. Finally, we trained a binary support vector machine to classify radiculopathy versus healthy subjects, as well as a 3-way classifier for subjects in the 3 groups. Both classifiers performed significantly better than chance, indicating that EEG features contain relevant information pertaining to sensory states, and may be used to help distinguish between pain states when other clinical signs are inconclusive.

Abstract
Objectives: To estimate the prevalence of chronic pain (CP) and high-impact chronic pain (HICP) in a sample of the general adult population in Saudi Arabia. Methods: This is a cross-sectional online survey (N=24,265). Forty data collectors from 5 regions of Saudi Arabia approached people to complete the questionnaires through different social media applications, using a validated survey in Arabic language. Results: Chronic pain and HICP prevalences in the Saudi adult population were found to be 46.4% (CP) and 4% (HICP), with a higher prevalence among women and elderly. Chronic back pain was the most reported pain location. Half of the respondents reported dissatisfaction with pain services. Greater prevalence of HICP was found among women, elderly, unemployed, and those with low-income status. Patients with HICP were more likely to have more healthcare utilization and have more negative impacts on their physical and psychological wellbeing. Conclusion: Chronic pain and HICP are common in Saudi Arabia, especially among females and elderly, suggesting a public health problem. This calls for collaborative efforts at various levels of the social hierarchy to ensure the provision of effective management of CP in Saudi Arabia.

Prevalence of chronic pain in developing countries: systematic review and meta-analysis. Pain Rep 2019; 4:e779. [PMID: 31984290 PMCID: PMC6903356 DOI: 10.1097/pr9.0000000000000779] [Citation(s) in RCA: 79] [Impact Index Per Article: 15.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Revised: 06/25/2019] [Accepted: 07/02/2019] [Indexed: 11/25/2022] Open
Abstract
Supplemental Digital Content is Available in the Text. Chronic pain (CP) is prevalent worldwide. Current reports on its prevalence in developing countries are heterogeneous, and to date, there is no quantitative synthesis providing a general estimation of its magnitude in the developing world. The goal of this study was to estimate the pooled prevalence of CP in the general population in developing countries. This was a PROSPERO-registered CRD42019118680 systematic review including population-based cross-sectional studies on CP from countries with ≤0.8 human developing index. We calculated prevalence using both random effects and fixed effects. Heterogeneity was calculated by the Cochran Q test and the I2 statistic. Publication bias was evaluated by visual inspection of the Egger funnel plot, as well as by the Begg rank test and the Egger linear test. Sources of heterogeneity were also explored in subgroup analyses. Twelve studies with a total of 29,902 individuals were included in this meta-analysis, of which 7263 individuals were identified with CP. The overall pooled prevalence of CP after correction for publication bias was 18% (95% confidence interval: 10%–29%), the sample presenting significant heterogeneity (I2 = 100%, P < 0.001). Subgroup analyses demonstrated that year of publication and the adopted threshold for pain chronicity could partially explain the observed heterogeneity (P < 0.05). The proportion of individuals with CP in the general population of developing countries was 18%. However, reports of prevalence have high variability, especially related to year of publication and the threshold level adopted for pain chronicity.

Abstract
OBJECTIVE The aim of this study was to estimate indirect cost (IC) related to chronic pain (CP) from an employer's perspective. METHODS A cost-of-illness study was performed on active workers and retirees due to CP, between October 2017 and March 2018, in one of the Brazilian public universities. IC was measured as a sum of absenteeism, presenteeism, and disability pensions. The analysis of factors associated with IC was based on Tweedie model. RESULTS CP had an average IC of R$9258.20 [95% confidence interval (95% CI) = 6907.37 to 11,950.17], which generates an impact of 6.42 million (95% CI = 4.37 to 10.99) per year, corresponding to 3.42% (95% CI = 2.33 to 5.85) of the payroll. The position (Measure of 2.00, 95% CI = 1.19 to 3.38) and pain intensity (Measure of 1.15; 95% CI = 1.02 to 1.30) presented independent association. CONCLUSION CP generates the high levels of IC for the education's employer. There is an urgent need to implement prevention programs aimed at improving CP control in the workplace.

Abstract
BACKGROUND Chronic pain (CP) can be a symptom of many underlying health issues. The consequences of CP may vary from slight discomfort to disruption of quality of life and normal functioning. In this study, we aim to investigate the prevalence of CP and its associated factors in Al Kharj, Saudi Arabia. METHODS This was a cross-sectional study conducted in Al Kharj, Saudi Arabia. We recruited 1031 participants for our study. Data was collected on socio-demographic, health predictors and anthropometric measurements (such as weight, height and waist circumference). The data analysis was performed on JMP®, Version 12. SAS Institute Inc., Cary, NC, 1989-2007. RESULTS The prevalence of self-reported chronic pain in Al Kharj population was 19% with a mean age of 26.4 (SD = 8.6) years. The most common locations of pain included; back pain (30%), abdominal pain (26%), headache (13%), and any musculoskeletal pain (56%). Multiple logistic regression revealed that presence of a chronic disease (OR = 3.8; 95% CI = 2.3-6.2), psychological disease (OR = 2.3; 95% CI = 1.2-4.3), high General Health Questionnaire (GHQ)-12 score (OR = 1.06; 95% CI = 1.03-1.1), and pack-years of smoking (OR = 1.05; 95% CI = 1.01-1.08) were significantly related to chronic pain in Al Kharj population. CONCLUSIONS Our study results found a high burden of chronic pain in this selected Saudi population. The most prevalent pain was low back pain. The presence of chronic and psychological diseases were strongly related to chronic pain. Future prospective studies are needed to establish the temporal relationship of chronic pain with these factors.

Abstract
Objective To describe the rate and demographics of pain among Vietnamese people in 48 provinces and describe the impact of pain on individuals, levels of satisfaction with treatment results, and behavior of pain sufferers. Methods The cross-sectional study was conducted in adults presenting to outpatient clinics throughout 48 provinces in Vietnam and were randomly selected for inclusion in this study. A physician trained to administer a questionnaire in a standardized fashion interviewed each patient and collected data regarding gender, age, career, acute and chronic pain, diagnoses, treatment, and satisfaction with treatment. Results There were 12,136 respondents (50.65% male and 49.35% female) from 48 of the 63 provinces in Vietnam. About 86.53% of respondents reported experiencing pain that affected their daily lives, with 24.10% complaining of acute pain and 62.43% having chronic pain. About 67.71% reported pain that affected job performance. Headache was the most common complaint in 35.43% of the respondents. Fewer than half (43.35%) of all patients with pain sought help from a doctor; only a quarter (27.50%) sought help within 1 month of experiencing that pain. A majority (61.98%) of patients who did seek help were satisfied with treatment results. The median cost of treatment was between 150 and 250 USD. Conclusion Pain severe enough to impact patients’ daily lives is common in Vietnam. Treatment costs are a significant economic burden and may help explain why only a minority of patients seek treatment. Access to lower cost, effective treatment for pain should be improved.

Abstract
In Libya neuropathic pain is rarely assessed in patients with diabetes. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain scale is used worldwide to screen for neuropathic pain. There is no Arabic version of LANSS for use in Libya. The aim of this study was to develop an Arabic version of LANSS and to assess its validity and reliability in diabetic patients in Benghazi, Libya. LANSS was translated into Arabic by four bilingual translators and back translated to English by a university academic. Validity and reliability of the Arabic LANSS was assessed on 110 patients attending a Diabetes Centre in Benghazi. Concurrent validity was tested and compared with the Self-completed Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS). Test-retest reliability was conducted 1-2 weeks later. Internal consistency and inter-class correlation (ICC) between LANSS and S-LANSS was also tested. Internal consistency within first completion of the Arabic LANSS was acceptable (Cronbach's alpha = 0.793) and similar to the Arabic S-LANSS (0.796) and the second completion of the Arabic LANSS (0.795). ICC between the Arabic LANSS and the Arabic S-LANSS was 0.999 (p < 0.001). Test-retest reliability (ICC) between first and second completions of the Arabic LANSS was 0.999 (p < 0.001). Kappa measurement of agreement between the two Arabic LANSS completions and S-LANSS was high on all seven items (Kappa >0.95, p < 0.0001). We concluded that the Arabic version of LANSS pain scale was valid and reliable for use on Libyan diabetic patients. This study provided results suggesting that the S-LANSS could also be used on diabetic patients.

Abstract
Puerarin is a major active ingredient of the traditional Chinese plant medicine, Radix Puerariae, and commonly used in the treatment of myocardial and cerebral ischemia. However, the effects of puerarin on neuropathic pain are still unclear. In this study, a neuropathic pain animal model was created by partial sciatic nerve ligation. Puerarin (30 or 60 mg/kg) was intraperitoneally injected once a day for 7 days. Mechanical allodynia and thermal hyperalgesia were examined at 1 day after model establishment. Mechanical threshold and paw withdrawal latency markedly increased in a dose-dependent manner in puerarin-treated rats, especially at 7 days after model establishment. At 7 days after model establishment, quantitative real-time reverse transcriptase-polymerase chain reaction results showed that puerarin administration reversed mRNA expression of transient receptor potential vanilloid 1 (Trpv1) and transient receptor potential ankyrin 1 (Trpa1) in a dose-dependent manner in dorsal root ganglion neurons after peripheral nerve injury. These results suggest that puerarin dose-dependently ameliorates neuropathic pain by suppressing Trpv1 and Trpa1 up-regulation in dorsal root ganglion of neuropathic pain rats.
