Short-term study on risk-benefit outcomes of two spinal manipulative therapies in the treatment of acute radiculopathy caused by lumbar disc herniation: study protocol for a randomized controlled trial. Trials 2015; 16:122. [PMID: 25872929 PMCID: PMC4380109 DOI: 10.1186/s13063-015-0634-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2014] [Accepted: 03/05/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND That patients with acute radiculopathy caused by lumbar disc herniation (LDH) will benefit from spinal manipulation (SM) treatment has been taken for granted, despite no solid evidence to support that claim. There is a demand for a win-win SM treatment that is both effective and less risky, and we attempt to use this trial to demonstrate such a treatment. In this study, Feng's Spinal Manipulative Therapy (FSM) is selected as the observational SM. FSM can be performed with either manipulation or mobilization, and also can be easily mimicked as a sham SM. METHODS/DESIGN Two hundred and sixteen qualified hospitalized participants will be randomly allocated to one of the three following groups: sham SM, mobilization, or manipulation, according to a ratio of 1:1:1. Participants in each group will receive specific FSM treatments four times, along with basic therapies over a course of 2 weeks. Two days after each SM appointment, risk outcomes will be assessed using a questionnaire developed to identify accompanying unpleasant reactions (AUR). The pain pressure threshold (PPT) will be measured paraspinally on the tender spot beside the involved joint before and immediately after each SM treatment. Relative risk (RR) of AUR, number needed to harm (NNH) and the 95% confidence intervals of each group will be calculated and compared. Benefit outcomes will be assessed by analyzing the following data recordings: the Numerical Rating Scale (NRS), Oswestry Disability Index (ODI), and Global Perceived Effect (GPE) before enrollment and at the 7th, and 15th day after the treatment. Analyses will include comparisons of NRS, ODI and changes at the different visit times among the three groups by Repeated Measures Data ANOVA, an evaluation of reduced scores of NRS and ODI after the therapy to determine if they meet the minimum acceptable outcome (MAO), and the determination of the minimal clinically important difference (MCID) by the average improvement in NRS and ODI scores of all participants who have been allocated to the category 'improved' on the GPE assessment. TRIAL REGISTRATION This trial is registered in Chinese Clinical Trial Register (ChiCTR) on 19 August 2013 ( ChiCTR-TRC-13003496 ).

Abstract
Population aging is the demographic phenomenon characterizing all countries in the world, and it is challenging the national infrastructures, in particular health systems. However, aging itself is not associated with increased medical spending, but disability and comorbidity that affect older individuals are the actual drivers for health expenditures. Therefore, if people age in better health, medical spending may be significantly reduced. Preventative interventions proved to be effective in reducing/preventing disease and disability and often found to be cost effective, include diet and exercise interventions, medications, routine disease screenings, and immunizations. Vaccination can protect older citizens against life-threatening diseases, such as influenza, pneumococcal infections, tetanus, and against diseases which adversely impact their quality of life, such as herpes zoster (HZ). Including HZ vaccination in its citizens' lifetime immunization calendar can reinforce Europe's commitment toward active, healthy aging. This paper outlines the consensus statement of a group of Italian experts on HZ.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is a common and costly surgical procedure. Despite high success rates, many TKA patients develop chronic pain in the months and years following surgery, constituting a public health burden. Pain catastrophizing is a construct that reflects anxious preoccupation with pain, inability to inhibit pain-related fears, amplification of the significance of pain vis-à-vis health implications, and a sense of helplessness regarding pain. Recent research suggests that it may be an important risk factor for untoward TKA outcomes. To clarify this impact, we systematically reviewed the literature to date on pain catastrophizing as a prospective predictor of chronic pain following TKA. METHODS We searched MEDLINE, EMBASE, and PsycINFO databases to identify articles related to pain catastrophizing, TKA, risk models, and chronic pain. We reviewed titles and abstracts to identify original research articles that met our specified inclusion criteria. Included articles were then rated for methodological quality. including methodological quality. Due to heterogeneity in follow-up, analyses, and outcomes reported across studies, a quantitative meta-analysis could not be performed. RESULTS We identified six prospective longitudinal studies with small-to-mid-sized samples that met the inclusion criteria. Despite considerable variability in reported pain outcomes, pain catastrophizing was identified as a significant predictor of chronic pain persisting ≥3 months following TKA in five of the studies assessed. Limitations of studies included lack of large-scale data, absence of standardized pain measurements, inadequate multivariate adjustment, such as failure to control for analgesic use and other relevant covariates, and failure to report non-significant parameter estimates. CONCLUSION This study provides moderate-level evidence for pain catastrophizing as an independent predictor of chronic pain post-TKA. Directions for future research include larger, well-controlled studies with standard pain outcomes, identification of clinically-relevant catastrophizing cut-offs that predict pain outcomes, investigation of other psychosocial risk factors, and assessment of interventions aimed to reduce pain catastrophizing on chronic pain outcomes following TKA surgery.

Abstract
Background Rehabilitation plays an important role to improve the outcomes of total knee arthroplasty (TKA). Evidence about the appropriate dose of exercise to recover gait dysfunction after TKA is limited. We posed the research question: In patients during the post-acute stage after TKA, is increased dose of exercise associated with larger improvements in gait parameters such as step length and single support time? Methods This was a secondary analysis from two randomized studies on exercise after TKA to investigate dose-dependence of gait parameters in response to exercise. Participants were 50 years or older who underwent unilateral TKA at least two months prior. They participated in 2 months of supervised exercises followed by 4 months of a home exercise program. The primary outcome was change in gait parameters from baseline to 6 months. Participants were divided in three groups according to the dose of exercise: group 1 (light-to-moderate intensity exercise), group 2 (high intensity + functional exercise), and group 3 (high intensity + functional + balance exercise). Jonckheere-Terpstra test was used to test if the magnitude of changes in gait parameters increased from group 1 to group 3 in an ordered fashion. Results Increased dose of exercise was associated with progressive increases in step length in the operated-limb (p=0.008) and decreases in step length in the non-operated limb (p=0.011). Increased dose of exercise was associated with ordinal decreases in loading response time (p=0.049) and increases in single-leg support time (p=0.021) on the operated- limb, but not on the non-operated-limb. Increased dose of exercise was associated with decreases in unloading time on the non-operated-limb (p=0.011) but not on the operated-limb (p=0.400). Conclusions Significant dose-response of exercise on gait parameters support the promotion of more intensive exercise programs that combine functional and balance training programs after TKA.

Abstract
ABSTRACT
Background
The purpose of this study is to compare between the open reduction and internal fixation (ORIF) using a volar plate and external fixation with K-wire fixation for the treatment of unstable distal radius fractures.
Materials and methods
This investigation was designed to prospectively evaluate the outcomes of similar distal radius fracture patterns treated by ORIF with volar plating vs closed reduction and pinning with external fixation.
Results
Open reduction and internal fixation with volar locking plate group has overall decrease incidence of complications significantly less radial shortening and significantly greater postoperative wrist motion when compared to external fixation.
Conclusion
Use of volar locking plate resulted in a faster recovery of function compared with external fixation. Use of volar locking plate resulted in better anatomical function and grip strength. However, no functional advantage was demonstrated at or beyond 12 weeks or 1 year.

Abstract
BACKGROUND Preincisional analgesia is an antinociceptive treatment that prevents altered central excitability from high-intensity noxious stimuli. To determine the analgesic efficacy of preoperative infiltration with bupivacaine for reduction mammaplasty, a randomized, double-blind, placebo-controlled trial was designed. METHODS Women with mammary hypertrophy were allocated randomly to one of two study groups. Patients in group I received preincision infiltration with bupivacaine into each breast after general anesthesia. Group II patients received similar injections of saline injection alone after general anesthesia. RESULTS Visual analogue pain score, verbal pain score, and short-form McGill Pain Questionnaire scores were higher in group II patients until 22 hours after surgery (p < 0.008). Patients in the saline group had higher intravenous meperidine consumption for 22 hours postoperatively and solicited opioids before the patients in the bupivacaine group (p < 0.001). The difference between groups was statistically significant. CONCLUSION Preincisional infiltration with bupivacaine results in reduced pain and lower postoperative opioid requirements in the early postoperative phase of pain following breast reduction.

Abstract
Previously published studies reported variable results using various suture techniques and reconstruction options for massive rotator cuff tears. Therefore, the current authors retrospectively studied 21 consecutive patients/shoulders with massive rotator cuff tears treated from January 2005 to October 2011 with a human dermal allograft through a mini-open approach. Mean patient age was 58 years (range, 33-72 years). Mean follow-up was 29 months (range, 18-52 months). Ten patients underwent revision repair for a failed rotator cuff repair. The authors measured the tendon gap (mean, 1.7 cm) and acromiohumeral interval (mean, 6.5 mm). They evaluated pain, shoulder range of motion (ROM) and function, patient satisfaction with the operation and outcome, and complications. At last follow-up, all patients experienced significant pain relief (P=.001) and improved ROM (P=.001) and American Shoulder and Elbow Surgeons (ASES) score (P=.001). Eighteen patients reported that they were satisfied or very satisfied and 3 reported that they were not satisfied with the operation and outcome. Comparison of outcomes between patients who underwent primary repair and those who underwent revision repair and between patients who had muscle atrophy and fatty infiltration grades 0 to II and those who had grades III to IV showed no statistically significant differences. A statistically significant correlation was observed between the size of the tendon gap and postoperative pain, ROM (except external rotation), and ASES score (P<.050). No significant correlation was observed between postoperative pain, ROM, and ASES score and the acromiohumeral interval (P>.050). Complications related to the dermal human allograft were not observed.

Abstract
OBJECTIVES The primary purpose of this study was to determine whether occurrences of within- and between-session changes were significantly associated with functional outcomes, pain, and self-report of recovery in patients at discharge who were treated with manual therapy for mechanical neck pain. A secondary purpose was to determine the extent of change needed for the within- and between-session change in association to function. METHODS This secondary data analysis examined 56 patients who demonstrated a positive response to manual therapy during the initial assessment within a randomized controlled trial (RCT) that examined manual therapy techniques and a home exercise program (HEP). Within- and between-session findings were defined as 'changes in pain report during the initial session (within)' and 'changes in pain from baseline to 48-hours post initial assessment (between)'. Outcomes were analyzed for associations with the global rating of change (GRoC), self-report activity scale (SRAS), and a 50% reduction of the neck disability index (NDI) by discharge at 96 hours. RESULTS Findings indicate that within-session pain changes of 36.7% are strongly associated with a 50% change in NDI at 96 hours. Between-session changes in pain were associated with 50% change in NDI and a ≧3-point change in GRoC at 96 hours. CONCLUSION Both within- and between-session measures may be useful to predict success levels at 96 hours for NDI; however, between-session changes are more useful to predict success in GRoC. Measures used during clinical examination may help guide clinicians in identification of candidates best suited for the treatment.

Abstract
BACKGROUND Somatoform disorders are characterised by chronic, medically unexplained physical symptoms (MUPS). Although different medications are part of treatment routines for people with somatoform disorders in clinics and private practices, there exists no systematic review or meta-analysis on the efficacy and tolerability of these medications. We aimed to synthesise to improve optimal treatment decisions. OBJECTIVES To assess the effects of pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform autonomic dysfunction, and pain disorder) in adults. SEARCH METHODS We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) (to 17 January 2014). This register includes relevant randomised controlled trials (RCTs) from The Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). To identify ongoing trials, we searched ClinicalTrials.gov, Current Controlled Trials metaRegister, the World Health Organization International Clinical Trials Registry Platform, and the Chinese Clinical Trials Registry. For grey literature, we searched ProQuest Dissertation & Theses Database, OpenGrey, and BIOSIS Previews. We handsearched conference proceedings and reference lists of potentially relevant papers and systematic reviews and contacted experts in the field. SELECTION CRITERIA We selected RCTs or cluster RCTs of pharmacological interventions versus placebo, treatment as usual, another medication, or a combination of different medications for somatoform disorders in adults. We included people fulfilling standardised diagnostic criteria for somatisation disorder, undifferentiated somatoform disorder, somatoform autonomic dysfunction, or somatoform pain disorder. DATA COLLECTION AND ANALYSIS One review author and one research assistant independently extracted data and assessed risk of bias. Primary outcomes included the severity of MUPS on a continuous measure, and acceptability of treatment. MAIN RESULTS We included 26 RCTs (33 reports), with 2159 participants, in the review. They examined the efficacy of different types of antidepressants, the combination of an antidepressant and an antipsychotic, antipsychotics alone, or natural products (NPs). The duration of the studies ranged between two and 12 weeks.One meta-analysis of placebo-controlled studies showed no clear evidence of a significant difference between tricyclic antidepressants (TCAs) and placebo for the outcome severity of MUPS (SMD -0.13; 95% CI -0.39 to 0.13; 2 studies, 239 participants; I(2) = 2%; low-quality evidence). For new-generation antidepressants (NGAs), there was very low-quality evidence showing they were effective in reducing the severity of MUPS (SMD -0.91; 95% CI -1.36 to -0.46; 3 studies, 243 participants; I(2) = 63%). For NPs there was low-quality evidence that they were effective in reducing the severity of MUPS (SMD -0.74; 95% CI -0.97 to -0.51; 2 studies, 322 participants; I(2) = 0%).One meta-analysis showed no clear evidence of a difference between TCAs and NGAs for severity of MUPS (SMD -0.16; 95% CI -0.55 to 0.23; 3 studies, 177 participants; I(2) = 42%; low-quality evidence). There was also no difference between NGAs and other NGAs for severity of MUPS (SMD -0.16; 95% CI -0.45 to 0.14; 4 studies, 182 participants; I(2) = 0%).Finally, one meta-analysis comparing selective serotonin reuptake inhibitors (SSRIs) with a combination of SSRIs and antipsychotics showed low-quality evidence in favour of combined treatment for severity of MUPS (SMD 0.77; 95% CI 0.32 to 1.22; 2 studies, 107 participants; I(2) = 23%).Differences regarding the acceptability of the treatment (rate of all-cause drop-outs) were neither found between NGAs and placebo (RR 1.01, 95% CI 0.64 to 1.61; 2 studies, 163 participants; I(2) = 0%; low-quality evidence) or NPs and placebo (RR 0.85, 95% CI 0.40 to 1.78; 3 studies, 506 participants; I(2) = 0%; low-quality evidence); nor between TCAs and other medication (RR 1.48, 95% CI 0.59 to 3.72; 8 studies, 556 participants; I(2) =14%; low-quality evidence); nor between antidepressants and the combination of an antidepressant and an antipsychotic (RR 0.80, 95% CI 0.25 to 2.52; 2 studies, 118 participants; I(2) = 0%; low-quality evidence). Percental attrition rates due to adverse effects were high in all antidepressant treatments (0% to 32%), but low for NPs (0% to 1.7%).The risk of bias was high in many domains across studies. Seventeen trials (65.4%) gave no information about random sequence generation and only two (7.7%) provided information about allocation concealment. Eighteen studies (69.2%) revealed a high or unclear risk in blinding participants and study personnel; 23 studies had high risk of bias relating to blinding assessors. For the comparison NGA versus placebo, there was relatively high imprecision and heterogeneity due to one outlier study. Although we identified 26 studies, each comparison only contained a few studies and small numbers of participants so the results were imprecise. AUTHORS' CONCLUSIONS The current review found very low-quality evidence for NGAs and low-quality evidence for NPs being effective in treating somatoform symptoms in adults when compared with placebo. There was some evidence that different classes of antidepressants did not differ in efficacy; however, this was limited and of low to very low quality. These results had serious shortcomings such as the high risk of bias, strong heterogeneity in the data, and small sample sizes. Furthermore, the significant effects of antidepressant treatment have to be balanced against the relatively high rates of adverse effects. Adverse effects produced by medication can have amplifying effects on symptom perceptions, particularly in people focusing on somatic symptoms without medical causes. We can only draw conclusions about short-term efficacy of the pharmacological interventions because no trial included follow-up assessments. For each of the comparisons where there were available data on acceptability rates (NGAs versus placebo, NPs versus placebo, TCAs versus other medication, and antidepressants versus a combination of an antidepressant and an antipsychotic), no clear differences between the intervention and comparator were found.Future high-quality research should be carried out to determine the effectiveness of medications other than antidepressants, to compare antidepressants more thoroughly, and to follow-up participants over longer periods (the longest follow up was just 12 weeks). Another idea for future research would be to include other outcomes such as functional impairment or dysfunctional behaviours and cognitions as well as the classical outcomes such as symptom severity, depression, or anxiety.

Abstract
Objective To evaluate the clinical utility of the electrically calculated quantitative pain degree (QPD) and to correlate it with subjective assessments of pain degree including a visual analogue scale (VAS) and the McGill Pain Questionnaire (MPQ). Methods We recruited 25 patients with low back pain. Of them, 21 patients suffered from low back pain for more than 3 months. The QPD was calculated using the PainVision (PV, PS-2100; Nipro Co., Osaka, Japan). We applied electrodes to the medial forearm of the subjects and the electrical stimulus was amplified sequentially. Minimum perceived current (MPC) and pain equivalent current (PEC) were defined as minimum electrical stimulation that could be sensed by the subject and electrical stimulation that could trigger actual pain itself. To eliminate individual differences, we defined QPD as the following: QPD=PEC-MPC/MPC. We scored pre-treatment QPD three times at admission and post-treatment QPD once at discharge. The VAS, MPQ, and QPD were evaluated and correlations between the scales were analyzed. Results Result showed significant test-retest reliability (ICC=0.967, p<0.001) and the correlation between QDP and MPQ was significant (at admission SRCC=0.619 and p=0.001; at discharge SRCC=0.628, p=0.001). However, the correlation between QPD and VAS was not significant (at admission SRCC=0.240, p=0.248; at discharge SRCC=0.289, p=0.161). Conclusion Numerical values measured with PV showed consistent results with repeated calculations. Electrically measured QPD showed an excellent correlation with MPQ but not with VAS. These results demonstrate that PV is a significantly reliable device for quantifying the intensity of low back pain.

Abstract
Skeletal muscles can be injured by their own contractions. Such contraction-induced injury, often accompanied by delayed onset of muscle soreness, is a leading cause of the loss of mobility in the rapidly increasing population of elderly people. Unlike other types of muscle injuries which hurt almost exclusively those who are subjected to intensive exercise such as professional athletes and soldiers in training, contraction induced injury is a phenomenon which may be experienced by people of all ages while performing a variety of daily-life activities. Subjects that experience contraction induced injury report on soreness that usually increases in intensity in the first 24 h after the activity, peaks from 24 to 72 h, and then subsides and disappears in a few days. Despite their clinical importance and wide influence, there are almost no studies, clinical, experimental or computational, that quantitatively relate between the extent of contraction induced injury and activity factors, such as number of repetitions, their frequency and magnitude. The lack of such quantitative information is even more emphasized by the fact that contraction induced injury can be used, if moderate and controlled, to improve muscle performance in the long term. Thus, if properly understood and carefully implemented, contraction induced injury can be used for the purpose of personalized training and recovery programs. In this paper, we review experimental, clinical, and theoretical works, attempting towards drawing a more quantitative description of contraction induced injury and related phenomena.

Abstract
Guidelines for postoperative pain treatment are based on patients' pain scores. Patients with an intermediate Numeric Rating Scale (NRS) score of 5 or 6 may consider their pain as either bearable or unbearable, which makes it difficult to decide on pain treatment because guidelines advise professionals to treat pain at NRS > 4. Educating patients in using an NRS score for pain might improve adequate pain treatment. A quasi-randomized controlled trial was conducted in which 194 preoperative patients watched the educational film and 183 the control film. Pain scores were considered discordant when patients reported an NRS ≤ 4 and wanted additional opioids or when patients reported an NRS > 4 and did not want additional opioids. Beliefs, fear, and knowledge of pain; pain assessment; and pain treatment were measured by questionnaires. No significant differences in discordant pain scores between the groups were found: relative risk (RR) 0.73, confidence interval (CI) 0.47-1.15 at rest and RR 0.96, CI 0.72-1.28 at movement. Patients in the intervention group had lower NRS pain scores than patients in the control group. In the intervention group, patients had significantly more knowledge and lower barriers to pain management compared with the control group. We did not find a statistically significant reduction in discordant pain scores when comparing the intervention group with the control group. However, patients in the intervention group had significantly lower pain scores, lower barriers, and more knowledge of pain treatment than patients in the control group.

Abstract
OBJECTIVE Endovenous techniques are, at present, the recommended choice for truncal vein treatment. However, the thermal techniques require tumescent anaesthesia, which can be uncomfortable during administration. Non-tumescent, non-thermal techniques would, therefore, have potential benefits. This randomised controlled trial is being carried out to compare the degree of pain that patients experience while receiving mechanochemical ablation or radiofrequency ablation. The early results of this randomised controlled trial are reported here. METHODS Patients attending for the treatment of primary varicose veins were randomised to receive mechanochemical ablation (ClariVein®) or radiofrequency ablation (Covidien® Venefit™). The most symptomatic limb was randomised. The primary outcome measure was intra-procedural pain using a validated visual analogue scale. The secondary outcome measures were change in quality of life and clinical scores, time to return to normal activities and work as well as the occlusion rate. RESULTS One-hundred and nineteen patients have been randomised (60 in the mechanochemical ablation group). Baseline characteristics were similar. Maximum pain score was significantly lower in the mechanochemical ablation group (19.3 mm, standard deviation ±19 mm) compared to the radiofrequency ablation group (34.5 mm ± 23 mm; p < 0.001). Average pain score was also significantly lower in the mechanochemical ablation group (13.4 mm ± 16 mm) compared to the radiofrequency ablation group (24.4 mm ± 18 mm; p = 0.001). Sixty-six percent attended follow-up at one month, and the complete or proximal occlusion rates were 92% for both groups. At one month, the clinical and quality of life scores for both groups had similar improvements. CONCLUSION Early results show that the mechanochemical ablation is less painful than the radiofrequency ablation procedure. Clinical and quality of life scores were similarly improved at one month. The long-term data including occlusion rates at six months and quality of life scores are being collected.

Abstract
Context: Central venous catheter (CVC) insertion induces pain and discomfort to a conscious patient despite application of a local anesthetic (LA) field block and this pain can be greatly lessened by using additional analgesics. Aim: The aim of this study is to evaluate the efficacy of fentanyl along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. Settings and Design: A prospective, randomized, double-blind, placebo-controlled trial was conducted at tertiary referral center. Materials and Methods: Fifty-four patients scheduled for planned CVC were randomly assigned to receive either fentanyl (2 μg/kg) or 0.9% normal saline. Pain and discomfort using a verbal numeric rating pain scale at 5 times points during CVC insertion were assessed and analyzed. Results: The median interquartile range pain score is worst for placebo group after LAI (5 [3-6]) and in the immediate postprocedure period (5 [4-5]) which was significantly attenuated by addition of fentanyl (3.5 [2-5] and 3 [2-4]) (P = 0.009 and 0.001 respectively). Overall, fentanyl and placebo group were not statistically different with median discomfort score except at T10 (P = 0.047). Conclusions: Preprocedural bolus fentanyl infusion provides adequate analgesia and can be safely used for alleviating pain during CVC insertion in conscious patients.

Abstract
BACKGROUND AND AIM Central venous catheter (CVC) insertion induces pain and discomfort to a conscious patient despite application of a local anaesthetic (LA) field block and this pain can be greatly lessened by using additional analgesics. The aim of this study was to evaluate the efficacy of dexmedetomidine along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. METHODS A prospective, randomised, double-blind, placebo-controlled trial of 54 patients scheduled for planned CVC insertion was undertaken. Patients were randomly assigned into two groups of 27 each, to receive either dexmedetomidine (1 μg/kg) or 0.9% normal saline, along with LA field infiltration. Pain and discomfort score was measured at 5 time points. RESULTS The median pain score was worst for placebo group at local anaesthetic injection (6 [4-7]) and at the end of procedure (5 [4-5]), which was significantly attenuated in the dexmedetomidine group (4 [4-5] and 4 [3-5]; P = 0.007 and 0.040 respectively). The lower procedure related discomfort score in the immediate post-procedural period was statistically significant in dexmedetomidine group compared to placebo (4 [4-5] vs. 5 [4-6]; P = 0.008). CONCLUSIONS Pre-procedural bolus dexmedetomidine infusion provides adequate analgesia and patient comfort for CVC insertion along LA field block. However, the tendency for excessive sedation and bradycardia associated with dexmedetomidine render it less desirable for this purpose.

Abstract
BACKGROUND Postoperative scapular fracture is a common complication after reverse shoulder arthroplasty (RSA). The purpose of this study was to determine its effect on RSA patient outcomes. METHODS A retrospective, case-control study of 25 nonoperatively treated postoperative scapular fractures after RSA were analyzed with a minimum 2-year follow-up from surgery and 1-year follow-up from fracture. Eligible patients were matched 1:4 to a control group for age, sex, follow-up time, surgery indication, and primary operation vs revision. Outcome measures, including American Shoulder and Elbow Surgeons (ASES) score and range of motion, were compared between fracture cases and controls. Also analyzed were radiographic features, including fracture location (acromion vs scapular spine) and healing. RESULTS Incidence of scapular fracture after RSA in this series was 3.1%. Fractures occurred from 1 to 94 months postoperatively. The revision rate was higher in the fracture group (8% vs. 2%) but did not reach statistical significance (P = .18). Fracture patients had improved (ΔASES, 21) but inferior clinical outcomes, with a postoperative ASES score of 58.0 compared with 74.2 (P ≤ .001). Change in range of motion also diminished in the fracture group, with a mean gain of 26° forward elevation compared with 76° (P < .001). Fracture location (P = .54) or healing (P = .40) did not affect outcome. CONCLUSION Postoperative scapular fractures may occur at any point postoperatively; increasing incidence is likely as longer follow-up becomes available. This complication leads to inferior clinical results compared with controls. However, patients show improvement compared with their preoperative measurements, even at longer-term follow-up. Patients with postoperative scapular fractures may have increased risk of revision. LEVEL OF EVIDENCE Level III, case-control study, treatment study.

Abstract
Pain is a complex issue with many different aspects concerning both sensorial and emotional experience. In recent years, the Health Promoting Hospitals (HPH) network has been encouraging a new vision in health structures, with the aim of reducing any form of pain wherever possible. Following the social representation approach, we explore the concept of 'pain' as it is continuously redefined, constructed and shared among health professionals involved in an HPH project named 'Hospital and District without Pain'. Three hundred and eighty-three professionals (doctors, nurses and local general practitioners referring to the hospital of Rovigo, Italy) were involved in a free association task with the aim of exploring the social representation of pain. Contents were further investigated by means of four focus group discussions. Results suggest that the representation of pain is strongly connected to medical knowledge and to functional aspects of the health practice. Other forms of pain-more relational, psychological or emotional-which do not fall within the aetiopathogenetic system of diagnosis, cannot be managed with the traditional tools of the health practice, and are not perceived to be handled with the professionals' competence. Results will be discussed in relation to general health promotion principles and to a specific initiative on the issue of pain carried out by the HPH-Veneto network.

Abstract
BACKGROUND Detection of ongoing spontaneous pain behaviors in laboratory animals remains a research challenge. Most preclinical pain studies measure elicited behavioral responses to an external noxious stimulus; however, ongoing spontaneous pain in humans and animals may be unrelated to hypersensitivity, and likely diminishes many behaviors, particularly motivated behaviors, that we hypothesize will decrease after induction of acute and chronic pain. METHODS In this study, 201 male rats were subjected to paw incision (INC), L5/L6 spinal nerve ligation (SNL), or INC in SNL rats, and the effects on paw withdrawal threshold (PWT) were assessed. For comparison, the behavioral-decreasing effects on nonevoked measures, including lever pressing for rewarding electrical stimulation of the ventral tegmental area intracranial self-stimulation (VTA ICSS) or food reinforcement (FR), and open field activity (OFA), were also assessed in these same rats. RESULTS INC decreased PWT for 4 days, decreased VTA ICSS for 2 days, and FR for 1 day but did not alter OFA. SNL decreased PWT similarly to INC but did not decrease VTA ICSS or FR; SNL did however decrease OFA. INC in SNL rats reduced PWT, VTA ICSS, and FR similarly to INC alone and did not decrease OFA compared with SNL alone. CONCLUSIONS The acute effects of INC on decreasing lever pressing for VTA ICSS and FR (1-2 days after incision) correspond to the timeframe in which ongoing spontaneous pain is expected to occur after INC. Therefore, these decreases are likely mediated by ongoing spontaneous pain, which may be unrelated to mechanical hypersensitivity that persists for up to 4 days after INC. PWT is decreased similarly by SNL, yet operant behavior (lever pressing for VTA ICSS and FR) was not decreased by SNL. SNL, but not INC, decreased rearing behavior but not total distance traveled during OFA. This further indicates that the presence and the extent of hypersensitivity are not predictive of many behavioral changes in rats thought to be mediated by the presence of ongoing pain. Surprisingly, the behavioral effects of INC are not exacerbated in SNL rats. These data support the growing belief that acute pain models produce short-lived spontaneous pain behaviors that are often less pronounced or absent in neuropathic pain models, and highlight the need for assessment of both evoked and nonevoked pain behaviors in developing future therapies for acute and chronic pain.

Abstract
PURPOSE Administration of sc morphine has been recommended two hours after the end of iv morphine titration in the postanesthesia care unit (PACU), but in some cases patients complain of pain earlier than this. We assessed pain after the end of iv morphine titration and studied the characteristics of patients who needed rescue sc morphine. METHODS Postoperative pain was assessed using the visual analogue scale (VAS; 0 to 100) and the threshold required to administer morphine in the PACU was a score of 30. VAS was measured every 15 min up to two hours after the end of iv morphine titration. Patients were divided into two groups, those who required sc morphine before two hours and those who did not. Data are expressed as mean +/- SD or odds ratio (OR; 95% confidence interval). RESULTS Four hundred and two patients were analyzed. Mean age was 51 +/- 19 yr, initial VAS 69 +/- 19, and the dose of iv morphine 11.7 +/- 6.6 mg. The number of patients requiring sc morphine within two hours was 84 (21%). These patients had more severe initial postoperative pain (73 +/- 20 vs 68 +/- 19, P < 0.05), and experienced sedation more frequently during morphine titration (45 vs 25%, P < 0.001). Using a multivariate analysis, occurrence of sedation during titration [OR 2.3 (1.4-3.8), P < 0.001] and an initial pain score > or = 60 [OR 1.9 (1.0-3.4), P < 0.05] were significantly associated with the need for rescue sc morphine. CONCLUSION Sedation during titration and an initial VAS > or = 60 are characteristics of the patients who require rescue (less than two hours) sc morphine after iv morphine titration.

Abstract
OBJECTIVES To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8 years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention. SETTING The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options. PARTICIPANTS The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8) years). Interview participants were selected using a purposive sampling list based on the RCT outcomes. OUTCOMES We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires. RESULTS Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item. CONCLUSIONS Elderly interview participants understood the importance of completing questionnaires for trial success. This led to strategies of completing the questionnaires that resulted in 'missing' or ambiguous data. To improve data collection in elderly populations, educational materials addressing the differential logics should be developed and tested. Pilot testing validated instruments using cognitive interviews may be particularly important in such populations. Finally, when the target of an intervention is a subjective experience, it seems important to create a method by which participants can convey their personal experiences. These could be nested qualitative studies. TRIAL REGISTRATION NUMBER ISRCTN77108101807.

Abstract
Objective: Posterior pilon fractures are rare injuries and have not yet gained well recognition. The purpose of this study was to present the treatment outcome for patients with posterior pilon fractures treated with buttress plate. Method: In this retrospective study we identified patients with posterior pilon fractures of the distal tibia who had undergone open reduction and internal fixation at our institute. Between January 2007 and December 2009, 10 patients (mean age, 46.5 years) who had undergone buttress plating via either a posterolateral approach or a dual posterolateral-posteromedial approach, were selected. All 10 patients were available for follow-up. The clinical outcome was evaluated with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS). The radiological evaluation was performed using the osteoarthritis-score (OA-score). Results: Satisfactory reduction and stable fixation were accomplished in all patients. At a mean follow-up of 36.2 months, all patients had good radiological results and showed satisfactory clinical recovery. The mean AOFAS sore was 87.8, the mean OA-score was 0.6, and the mean VAS scores during rest, active motion, and weight-bearing walking were 0.6, 0.8, and 1.4, respectively. Conclusion: Buttress plating for posterior pilon fractures gave satisfactory clinical outcomes. It also ensured rigid fixation which in turn enabled earlier postoperative mobilization.

Abstract
STUDY DESIGN Randomized clinical trial. OBJECTIVE To compare the effectiveness of manual therapy and exercise (MTEX) to a home exercise program (HEP) in the management of individuals with an inversion ankle sprain. BACKGROUND An in-clinic exercise program has been found to yield similar outcomes as an HEP for individuals with an inversion ankle sprain. However, no studies have compared an MTEX approach to an HEP. METHODS Patients with an inversion ankle sprain completed the Foot and Ankle Ability Measure (FAAM) activities of daily living subscale, the FAAM sports subscale, the Lower Extremity Functional Scale, and the numeric pain rating scale. Patients were randomly assigned to either an MTEX or an HEP treatment group. Outcomes were collected at baseline, 4 weeks, and 6 months. The primary aim (effects of treatment on pain and disability) was examined with a mixed-model analysis of variance. The hypothesis of interest was the 2-way interaction (group by time). RESULTS Seventy-four patients (mean ± SD age, 35.1 ± 11.0 years; 48.6% female) were randomized into the MTEX group (n = 37) or the HEP group (n = 37). The overall group-by-time interaction for the mixed-model analysis of variance was statistically significant for the FAAM activities of daily living subscale (P<.001), FAAM sports subscale (P<.001), Lower Extremity Functional Scale (P<.001), and pain (P ≤.001). Improvements in all functional outcome measures and pain were significantly greater at both the 4-week and 6-month follow-up periods in favor of the MTEX group. CONCLUSION The results suggest that an MTEX approach is superior to an HEP in the treatment of inversion ankle sprains. Registered at clinicaltrials.gov (NCT00797368).

Abstract
Studies of balance and risk factors for falling typically focus on the elderly population or on individuals with musculoskeletal pain. Although fibromyalgia is associated with intrinsic factors that predispose to falls (pain, depression, fatigue), few studies have researched balance and falls in this syndrome. The aim of this study was to verify the association between balance, balance self-efficacy and pain in women with and without fibromyalgia, and verify the association between Berg Balance Scale and Activities-specific Balance Confidence Scale (ABC Scale). The sample consisted of 48 women aged between 40 and 59 years, divided into two groups: Fibromyalgia group (n=22) and Control group (n=26) with asymptomatic people. Balance was assessed by Berg Balance Scale, balance self-efficacy by the ABC Scale and pain by the visual analog scale. Mean scores for pain, Berg and ABC Scale were 5.4 cm (SD 2.6), 55 (interquartile range 54-56), and 54.6 (SD 26.6) respectively for Fibromyalgia group, and 0 cm, 56 (interquartile range 55-56), and 89.4 (SD 14.4) respectively for Control group. Statistically significant differences were found in balance on comparing both groups (p=0.000 for Berg Balance Scale and 0.009 for ABC Scale) with lower values for Fibromyalgia group. In Fibromyalgia group, pain was negatively correlated with balance (r=-0.48, p=0.020) and balance self-efficacy (rs=-0.56, p=0.006). Correlation between Berg Balance Scale and ABC Scale was found only in the Fibromyalgia group (rs =0.55, p=0.007). There are associations between poor balance and pain, and poor balance and decreased balance self-efficacy in women with fibromyalgia. There is an association between scales in the Fibromyalgia group.

Abstract
BACKGROUND The development of clinical practice guidelines for managing spinal pain have been informed by a biopsychosocial framework which acknowledges that pain arises from a combination of psychosocial and biomechanical factors. There is an extensive body of evidence that has associated various psychosocial factors with an increased risk of experiencing persistent pain. Clinicians require instruments that are brief, easy to administer and score, and capable of validly identifying psychosocial factors. The pain diagram is potentially such an instrument. The aim of our study was to examine the association between pain diagram area and psychosocial factors. METHODS 183 adults, aged 20-85, with spinal pain were recruited. We administered a demographic checklist; pain diagram; 11-point Numerical Rating Scale assessing pain intensity; Pain Catastrophising Scale (PCS); MOS 36 Item Short Form Health Survey (SF-36); and the Fear Avoidance Beliefs Questionnaire (FABQ). Open source software, GIMP, was used to calculate the total pixilation area on each pain diagram. Linear regression was used to examine the relationship between pain diagram area and the following variables: age; gender; pain intensity; PCS total score; FABQ-Work scale score; FABQ-Activity scale score; and SF-36 Mental Health scale score. RESULTS There were no significant associations between pain diagram area and any of the clinical variables. CONCLUSION Our findings showed that that pain diagram area was not a valid measure to identify psychosocial factors. Several limitations constrained our results and further studies are warranted to establish if pain diagram area can be used assess psychosocial factors.

Abstract
Drug-eluting stents are largely used in coronary arteries and more recently in tibial arteries owing to their potentially better outcomes compared with bare metal stents. A patient with polyarteritis nodosa and critical limb ischemia and a dorsal foot ulcer was previously unsuccessfully treated with multiple angioplasties and subsequently underwent implantation of a drug-eluting stent in the pedal artery. At 6 months, stent patency on color Doppler ultrasound and complete healing of the foot ulcer were observed.

Abstract
AIM The purpose of this study was to determine the anesthetic efficacy of inferior alveolar nerve block (IANB) using 4% articaine and 2% lidocaine supplemented with buccal infiltration. MATERIALS AND METHODS Forty five patients, diagnosed with irreversible pulpitis of a mandibular posterior tooth were included in the study. The first group of 15 patients received 2% lidocaine with 1:200000 epinephrine, the second group 2% lidocaine with 1: 80,000 epinephrine and the third group of 15 subjects received 4% articaine with 1:100000 epinephrine. During the access cavity preparation those patients who complained of pain received an additional buccal infiltration. The percentage of subjects who got profound anesthesia and failure to achieve anesthesia were calculated and tabulated using a visual analog scale. RESULTS The results revealed that 87% of subjects who received 4% Articaine with 1:100,000 epinephrine got satisfactory anesthesia with inferior alveolar nerve block alone. Only 2 (13%) subjects received an additional buccal infiltration and none of the patients failed to obtain complete anesthesia with articaine. In comparison only 40% of subjects got complete anesthesia with 2% lidocaine with 1:200000 and 60% with 2% lidocaine with 1:80,000. CONCLUSION It can be concluded that 4% articaine can be used effectively for obtaining profound anesthesia for endodontic procedures in patients with irreversible pulpitis.

Abstract
This randomized controlled study addressed whether sonographic needle guidance affected the outcomes of corticosteroid injection for symptomatic carpal tunnel syndrome. Seventy-seven symptomatic carpal tunnels were randomized to injection by either (1) conventional anatomic landmark palpation-guided injection or (2) sonographic image-guided injection, each using a two-step technique where 3 ml of 1% lidocaine was first injected to hydrodissect and hydrodisplace critical intra-carpal tunnel structures followed by injection with 80 mg of triamcinolone acetonide (2 ml). Baseline pain, procedural pain, pain at outcome (2 weeks and 6 months), responders, therapeutic duration, total cost, and cost per responder were determined. There were no complications in either treatment group. Relative to conventional anatomic landmark palpation-guided methods, sonographic guidance for injection of the carpal tunnel resulted in 77.1% reduction in injection pain (p<0.01), a 63.3% reduction in pain scores at outcome (p<0.014), 93.5% increase in the responder rate (p<0.001), 84.6% reduction in the non-responder rate (p<0.001), a 71.0% increase in therapeutic duration (p<0.001), and a 59.3% ($150) reduction in cost/responder/year for a hospital outpatient (p<0.001). However, despite improved outcomes, cost per patient per year was significantly increased for an outpatient in a physician's office and was neutral for a hospital outpatient. Sonographic needle guidance significantly improves the performance and clinical outcomes of injection of the carpal tunnel and is cost-effective for a hospital-based practice, but based on current reimbursements, it significantly increases overall costs for medical care delivered in a non-hospital-based physician practice.

Abstract
BACKGROUND Various adjuvants are being used with local anesthetics for prolongation of intraoperative and postoperative analgesia. Dexmedetomidine, the highly selective 2 adrenergic agonist is a new neuraxial adjuvant gaining popularity. SETTINGS AND DESIGN The study was conducted in prospective, double blind manner. It included 120 American Society of Anesthesiology (ASA) class I and II patients undergoing lower limb surgery under spinal anesthesia after approval from hospital ethics committee with written and informed consent of patients. MATERIALS AND METHODS The patients were randomly allocated into four groups (30 patients each). Group BS received 12.5 mg hyperbaric bupivacaine with normal saline, group BF received 12.5 mg bupivacaine with 25 g fentanyl, group BC received 12.5 mg of bupivacaine supplemented 30 g clonidine, and group BD received 12.5 mg bupivacaine plus 5 g dexmedetomidine. The onset time to reach peak sensory and motor level, the regression time of sensory and motor block, hemodynamic changes, and side effects were recorded. RESULTS Patients in Group BD had significantly longer sensory and motor block times than patients in Groups BC, BF, and BS with Groups BC and BF having comparable duration of sensory and motor block. The mean time of two segment sensory block regression was 147 ± 21 min in Group BD, 117 ± 22 in Group BC, 119 ± 23 in Group BF, and 102 ± 17 in Group BS (P > 0.0001). The regression time of motor block to reach modified Bromage zero (0) was 275 ± 25, 199 ± 26, 196 ± 27, 161 ± 20 in Group BD, BC, BF, and BS, respectively (P > 0.0001). The onset times to reach T8 dermatome and modified Bromage 3 motor block were not significantly different between the groups. Dexmedetomidine group showed significantly less and delayed requirement of rescue analgesic. CONCLUSIONS Intrathecal dexmedetomidine is associated with prolonged motor and sensory block, hemodynamic stability, and reduced demand of rescue analgesics in 24 h as compared to clonidine, fentanyl, or lone bupivacaine.

Abstract
STUDY DESIGN Parallel-group randomized controlled trial. OBJECTIVE Establish the short-term effectiveness of chiropractic therapy for spinal pain compared with a sham intervention and explore the predictors of chiropractic treatment satisfaction. SUMMARY OF BACKGROUND DATA Chiropractic treatment is widely used for spinal pain. However, a lack of sound evidence precludes conclusions about the effectiveness of chiropractic for spinal pain. METHODS Participants were adults experiencing spinal pain, randomized to receive 2 treatments of chiropractic or sham therapy. Participants and outcome assessors were blinded to group allocation. Primary outcomes at 2 weeks were pain intensity (0-10 scale) and function (0-40 Functional Rating Index). Secondary outcomes were global change, minimum acceptable outcome, and treatment satisfaction. Treatment effects were estimated with linear mixed models for the primary outcomes. We used logistic regression to identify differences in the secondary outcomes and explore for predictors of treatment satisfaction. RESULTS One hundred eighty three participants (chiropractic, n = 92; sham, n = 91) were recruited and included in the analyses. Participants receiving chiropractic therapy reported greater improvements in pain (mean difference, 95% confidence interval [CI] = 0.5 [0.1-0.9]), physical function (mean difference [95% CI] = 2.1 [0.3-4.0]), and were more likely to experience global improvement (48% vs. 24%, P = 0.01) and treatment satisfaction (78% vs. 56%, P < 0.01). There was no between-group difference in achieving a minimally acceptable outcome (34% sham vs. 29% chiropractic, P = 0.42). Awareness of treatment assignment and achieving minimally important improvement in pain intensity were associated with chiropractic treatment satisfaction. CONCLUSION Short-term chiropractic treatment was superior to sham; however, treatment effects were not clinically important. Awareness of treatment assignment and clinically important reductions in pain were associated with chiropractic treatment satisfaction. LEVEL OF EVIDENCE 2.

Abstract
Purpose: This study evaluated retraction in the setting of acute rotator cuff tears and determined its effects on patient outcomes and tendon repair integrity. Materials and Methods: A total of 22 patients had surgery within 6 weeks or less from the time of injury. Fifteen of these patients were prospectively followed at a minimum of 2 years; average 40.5 months (range 24-69). Pre-operative objective and subjective outcomes were compared. Tendon repair integrity was assessed with ultrasound at a minimum of 1 year from surgery. The population was stratified into Group 1 (8 patients) with minimal intra-operative medial tendon retraction to the mid-line level of the humeral head and Group 2 (7 patients) with a large medial tendon retraction to the glenohumeral joint or greater. Results: The average time to surgery from the onset of symptoms was 27 days (range, 6-42). Post-operative motion increased significantly for external rotation and forward elevation, 77% of patients were pain free, 80% were completely satisfied, and 100% would have the surgery again. Group 1 (small retraction) versus Group 2 (large retraction) showed that post-operative pain levels, satisfaction, range of motion, strength, subjective shoulder value (95.4% vs. 92.3%), Constant Score (80.8 vs. 78.1), and American Society of Shoulder and Elbow Surgeons (96.2 vs. 93.5) scores were not statistically different. Ultrasound showed a tendon repair integrity rate of 87%. 2 patients who did have a re-tear were in Group 2, yet had comparative outcomes. Conclusion: In acute rotator cuff tears, equal patient satisfaction, pain scores, range of motion, strength, and outcome measures should be expected with surgical repair despite the level of retraction.

Abstract
STUDY DESIGN Blinded parallel-group randomized controlled trial. OBJECTIVE Establish the frequency and severity of adverse effects from short-term usual chiropractic treatment of the spine when compared with a sham treatment group. SUMMARY OF BACKGROUND DATA Previous studies have demonstrated that adverse events occur during chiropractic treatment. However, as a result of design limitations in previous studies, particularly the lack of sham-controlled randomized trials, understanding of these adverse events and their relation with chiropractic treatment is suboptimal. METHODS We conducted a trial to examine the occurrence of adverse events resulting from chiropractic treatment. It was conducted across 12 chiropractic clinics in Perth, Western Australia. The participants comprised 183 adults, aged 20 to 85 years, with spinal pain. Ninety-two participants received individualized care consistent with the chiropractors' usual treatment approach; 91 participants received a sham intervention. Each participant received 2 treatments. RESULTS Completed adverse questionnaires were returned by 94.5% of the participants after appointment 1 and 91.3% after appointment 2. Thirty-three percent of the sham group and 42% of the usual care group reported at least 1 adverse event. Common adverse events were increased pain (sham 29%; usual care 36%), muscle stiffness (sham 29%; usual care 37%), and headache (sham 17%; usual care 9%). The relative risk (RR) was not significant for adverse event occurrence (RR = 1.24; 95% CI: 0.85-1.81), occurrence of severe adverse events (RR = 1.9; 95% CI: 0.98-3.99), adverse event onset (RR = 0.16; 95% CI: 0.02-1.34), or adverse event duration (RR = 1.13; 95% CI: 0.59-2.18). No serious adverse events were reported. CONCLUSION A substantial proportion of adverse events after chiropractic treatment may result from natural history variation and nonspecific effects.

Abstract
BACKGROUND Quality of life is an important issue in endocrine tumors because of the high prevalence of benign tumors and the indolent course of most malignant tumors. OBJECTIVE To evaluate the frequency and the intensity of pain and anxiety in patients undergoing thyroid nodule fine-needle aspiration cytology (FNAC) and to identify factors associated with pain. METHODS Single center prospective study in the setting of a one-stop outpatient diagnostic clinic for thyroid nodules. Pain was evaluated using a 100-mm visual analogue scale (VAS) immediately following (VAS1) and 30 minutes after (VAS2) FNAC and was considered significant if ≥ 30. Anxiety symptoms were assessed prior to FNAC using a self-report measure questionnaire: the state form of Spielberger State-Trait Anxiety Inventory (STAI, form Y-A). FNAC was performed with a 25-gauge needle and a moderate aspiration and two passes for each nodule. RESULTS Two hundred eighteen consecutive patients (163 females, 55 males; mean age 53 years, range 12-84 years) undergoing FNAC of one to three nodules were included. VAS1 was ≥ 30 in 24% of the patients and VAS(2) was ≥ 30 in 13% of the patients. Independent significant factors correlated to a VAS1 of ≥ 30 were age under 25 years and the number of nodules being biopsied. Independent significant factors correlated to a VAS2 of ≥ 30 were VAS1 ≥ 30 and female sex. No correlation was found between pain and nodule size or nodule depth, nor the duration of application of the eutectic mixture of local anesthetics (EMLA) patch prior to FNAC. The mean STAI score for anxiety was 37 ± 12. The average STAI score was significantly higher in women (39) than in men (33; p = 0.01). There was no significant correlation between STAI score and age under 25 years, previous FNAC, number of nodules biopsied, or acetaminophen administration, but the STAI score was significantly correlated to VAS1 and VAS2. CONCLUSIONS FNAC-related pain is frequent and correlates with the number of nodules biopsied, age under 25 years, female sex, and anxiety.

Abstract
BACKGROUND Complaints of the arm, neck, or shoulder (CANS) have a multifactorial origin and cause considerable work problems, including decreased work productivity, sickness absence, and, ultimately, job loss. There is a need for intervention programs for people with CANS. Self-management is an approach used in chronic disease care to improve self-efficacy and wellness behaviors to facilitate participants to make informed choices and carry them out. This study will evaluate the effectiveness of a self-management program (including ehealth) and compare it to usual care among employees with chronic CANS (lasting >3 months). METHODS/DESIGN This is a randomized controlled trial in which 142 participants will be recruited and randomized (with pre-stratification) to either the intervention group (IG) or control group (CG). The IG will participate in a self-management program consisting of six group sessions and an ehealth module. The CG is allowed to use all usual care available. The primary outcome of the study is the self-reported disability of arm, shoulder, and hand, measured with the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). Secondary outcomes include: absenteeism, pain in the previous week, quality of life, catastrophizing pain, self-efficacy, workstyle, presenteeism, fatigue, the use of usual care, and limitations experienced on the job. Data are collected at baseline and at 3, 6, and 12 months follow-up. DISCUSSION Following the process of intervention mapping we developed a self-management program to suit and alleviate the problems and needs of employees with CANS. A strength of the study is that our intervention is specifically tailored to match the needs of employees with CANS. The study also has some potential weaknesses (for example, use of co-interventions, combination of group sessions and ehealth, self-reporting of data and possible contamination, Hawthorne effect, and recall or information bias) which are discussed. TRIAL REGISTRATION The trial is registered with the Dutch Trial Register (http://www.trialregister.nlNTR3816): (January 2013). The first participant was randomized in September 2012.

Abstract
Background: Homeless people are known to suffer disproportionately with health problems that reduce physical functioning and quality of life, and shorten life expectancy. They suffer from a wide range of diseases that are known to be painful, but little information is available about the nature and prevalence of chronic pain in this vulnerable group. This study aimed to estimate the prevalence of chronic pain among homeless people, and to examine its location, effect on activities of daily living, and relationship with alcohol and drugs. Methods: We conducted face-to-face interviews with users of homeless shelters in four major cities in the United Kingdom, in the winters of 2009-11. Participants completed the Brief Pain Inventory, Short Form McGill Pain questionnaire, Leeds Assessment of Neuropathic Symptoms and Signs, and detailed their intake of prescribed and unprescribed medications and alcohol. We also recorded each participant’s reasons for homelessness, and whether they slept rough or in shelters. Findings: Of 168 shelter users approached, 150 (89.3%) participated: 93 participants (63%) reported experiencing pain lasting longer than three months; the mean duration of pain experienced was 82.2 months. The lower limbs were most frequently affected. Opioids appeared to afford a degree of analgesia for some, but whilst many reported symptoms suggestive of neuropathic pain, very few were taking anti-neuropathic drugs. Interpretation: The prevalence of chronic pain in the homeless appears to be substantially higher than the general population, is poorly controlled, and adversely affects general activity, walking and sleeping. It is hard to discern whether chronic pain is a cause or effect of homelessness, or both. Pain is a symptom, but in this challenging group it might not always be possible to treat the underlying cause. Exploring the diagnosis and treatment of neuropathic pain may offer a means of improving the quality of these vulnerable people’s lives.

Abstract
The objective of this study was to compare the cost and safety of intrathecal injection (IN) vs. epidural infusion (CE) trial and to provide a preliminary assessment of the prognostic value of each in the selection of patients for long-term continuous intrathecal opioid therapy (CIOT). Thirty-seven patients with chronic nonmalignant pain who were being considered for CIOT were randomized to morphine trial by IN or CE. Analgesic response and complications were monitored throughout trial. Sixty-seven percent of IN (12/18) and 79% (15/19) of CE subjects reported good pain relief (defined as ≥ 50% pain reduction) and were implanted with a permanent infusion system. Eighty-nine percent (24/27) of subjects provided six-month CIOT follow-up data. Cost of trial and health care utilization during six months of CIOT were compared between groups. Analgesic and functional response during CIOT was also compared between IN and CE groups. The cost of IN trial was significantly less than CE trial (p < 0.001). Complications were generally mild in both groups, although opioid-related side effects tended to be more common in the IN group. Successful pain relief after six months of CIOT was reported by 10 (60%) and 14 (64%) patients who underwent IN and CE trial, respectively (p = 0.32; Fisher's exact test). There was no difference between IN and CE groups in McGill Pain rating, quality of life (VAS), mood (Profile of Mood States), or function (Sickness Impact Profile) after six months of CIOT. We conclude that intrathecal injection is a safe procedure for use in selection of patients for CIOT and is less costly than epidural infusion. Differences in pain and functional response to long-term opioids among patients selected by either trial method are not large.

Abstract
Herpes zoster and post-herpetic neuralgia deteriorate the quality of life because of severe pain and complications, and cause considerable social and economic burden of disease. In 2012, herpes zoster vaccine was released in Korea. The efficacy of herpes zoster vaccine is known to be 51.3-66.5% among the aged over 60 and 69.8-72.4% among adults between 50 and 59. It is also known that preventive efficacy is maintained for at least 5 years. Although there can be local reactions such as redness, pain and swelling at the site of injection and systemic reaction such as headache and eruption after herpes zoster vaccination, most of the adverse reactions are minor and disappear within days by themselves. As it is a live vaccine, persons with severe immune-suppression and pregnant women should not be vaccinated with the vaccine. Currently, Korean Society of Infectious Diseases recommended for the aged over 60 to be vaccinated with herpes zoster vaccine by subcutaneous route. In this article, clinical aspects and burden of disease of herpes zoster, efficacy and effects of herpes zoster vaccine, and herpes zoster vaccine recommendation by Korean Society of Infectious Diseases are discussed.

Abstract
Few clinical studies have reported polyetheretherketone (PEEK) rod pedicle screw spinal instrumentation systems (CD-Horizon Legacy PEEK rods; Medtronic, Minneapolis, Minnesota). This article describes a clinical series of 52 patients who underwent posterior spinal fusion using the PEEK Rod System between 2007 and 2010. Of the 52 patients, 25 had degenerative disk disease, 10 had lateral recess stenosis, 6 had degenerative spondylolisthesis, 6 had lumbar spine vertebral fracture, 4 had combined lateral recess stenosis and degenerative spondylolisthesis, and 1 had an L5 giant cell tumor. Ten patients had 1-segment fusion, 29 had 2-segment fusion, and 13 had 3-segment fusion. Mean follow-up was 3 years (range, 1.5-4 years); no patient was lost to follow-up. Clinical evaluation was performed using the Oswestry Disability Index and a low back and leg visual analog pain scale. Imaging evaluation of fusion was performed with standard and dynamic radiographs. Complications were recorded. Mean Oswestry Disability Index scores improved from 76% preoperatively (range, 52%-90%) to 48% at 6 weeks postoperatively, and to 34%, 28%, and 30% at 3, 6, and 12 months postoperatively, respectively. Mean low back and leg pain improved from 8 and 9 points preoperatively, respectively, to 6 and 5 points immediately postoperatively, respectively, and to 2 points each thereafter. Imaging union of the arthrodesis was observed in 50 (96%) patients by 1-year follow-up. Two patients sustained screw breakage: 1 had painful loss of sagittal alignment of the lumbar spine and underwent revision spinal surgery with pedicle screws and titanium rods and the other had superficial wound infection and was treated with wound dressing changes and antibiotics for 6 weeks. No adjacent segment degeneration was observed in any patient until the time of this writing.

Abstract
The sore throat pain model was employed in this randomized, placebo-controlled trial to examine the sensitivity of the model in testing the efficacy of valdecoxib as an acute analgesic drug. Changes were made to the study design by employing a different diagnostic index for tonsillo-pharyngitis, a different rating scale (derived from Lasagna's pain thermometer), and alternative analyses, individual responder rates. Under double-blind conditions, 197 patients with painful pharyngitis were randomly allocated to valdecoxib 20 mg bid (n = 65), valdecoxib 40 mg qd (n = 66), or placebo (n = 66) for 24 hours. The expanded Tonsillo-Pharyngitis Assessment and the Lasagna Pain Scale were validated as sensitive study instruments. Both dosage regimens provided significantly greater pain relief compared with placebo on standard efficacy measures over the 24-hour study (all P < .05). Tests for individual response (eg, percentage of patients with at least moderate relief) confirmed these results, and other response rates identified the high sensitivity of the model itself (eg, only 5% of placebo-treated patients achieved >or=50% of maximum total pain relief over 6 hours). These findings indicate that sore throat is a sensitive model to assess analgesic efficacy.
