A Comparison of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) and Pain Assessment in Advanced Dementia Scale (PAINAD).

BACKGROUND: There is currently no gold standard instrument for assessing pain in severely cognitively impaired adults who are unable to provide self-report. AIMS: To determine interrater reliability of the PACSLAC and PAINAD in assessing pain behaviors in patients with the same pain stimulus, determine the consistency of the reliable changes between and within the instruments and assess nurse preference for either instrument. DESIGN: A single-group, within-subjects repeated-measures design was implemented. SETTING: The study took place in a small suburban hospital. PARTICIPANTS/SUBJECTS: Pain levels were observed at 24, 48, and 72 hours postsurgery using two instruments: Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) and Pain Assessment in Advanced Dementia Scale (PAINAD). These instruments were selected because they are among the most commonly recommended tools for clinical use. Interrater reliability was analyzed along with reliable changes in pain for each period, and the study concluded with the nurse raters completing a preference survey. METHODS: A convenience sample of 30 patients was used with a diagnosis of severe dementia rendering the patient unable to reliably express pain, 60+ years of age, recovering from hip fracture surgery. RESULTS: Greater interrater reliability was found for the PACSLAC, with reliable change potentially affected by the type and level of pain medication. The nurses' preference for the tool was split. CONCLUSIONS: The results of this study indicate that the PACSLAC may be the more reliable tool over the PAINAD; however, rater training and familiarity with the tool is critical.

The impact of preoperative opioid use on outcomes after elective colorectal surgery: A propensity-matched comparison study.

BACKGROUND: The impact of recent preoperative opioid exposure on outcomes of colorectal surgery is unclear. Our aim was to evaluate the impact of preoperative opioid use on outcomes and opioid prescribing patterns after colorectal surgery. METHODS: We performed a retrospective review of all patients undergoing elective resection at a single institution from 2015 to 2017. Primary outcomes included in-hospital narcotic use and cost. Secondary outcomes included postoperative surgical outcomes and discharge prescribing patterns. RESULTS: A total of 390 patients underwent elective colorectal surgery, of whom 63 (16%) had a recent history of preoperative opioid use. Opioid users had similar age, sex, American Society of Anesthesiologists score, and operative indication compared with opioid-naïve patients (P > .05 for each). Postoperatively, the 30-day readmission rate was greater among opioid users (18% vs 9%, P = .03). Opioid users had greater total narcotic use (218 morphine milligram equivalents vs 111 morphine milligram equivalents, P = .04) and direct costs ($11,165 vs $8,911, P < .01). These patients were also more likely to require an opioid prescription on discharge (90% vs 68%, P < .01) and an opioid refill within 30 days (54% vs 21%, P < .01). CONCLUSION: Recent preoperative opioid exposure among colorectal surgery patients was associated with increased opioid consumption and costs. Moreover, unadjusted analysis was pertinent for more readmissions after surgery among preoperative opioid users. This work underscores the negative impact of preoperative, chronic opioid use on surgical outcomes and highlights the need for developing protocols to minimize perioperative narcotics.

Assessment of conditioned pain modulation in healthy participants and patients with chronic pain: manifestations and implications for pain progression.

PURPOSE OF REVIEW: The purpose of this review is to summarize recent findings on conditioned pain modulation (CPM) in humans with a focus on methodology, factors modulating CPM, and the potential for CPM as a clinical marker for pain progression. RECENT FINDINGS: CPM can be evoked by combining different stimulus modalities with good reliability; sequential CPM effects are stable over time with limited carryover effects. Optimism and pain catastrophizing might influence pain inhibition. Further, studies suggest that the CPM effect can be improved by gabapentinoids, transcranial direct current stimulation to cortical structures, and exercise and that long-term opioid use might impair CPM in patients with chronic pain. Clinical evidence suggests that preoperative impaired CPM may predict more severe chronic postoperative pain. The effect of pain duration on CPM impairment has been challenged by recent studies. SUMMARY: As CPM methodology is optimized, studies are revealing factors that can modulate descending pain inhibitory pathways. Understanding underlying mechanisms of CPM will improve the utility of CPM in a clinical setting and potentially lead to personalized treatments for chronic pain patients.

Late Shoulder-Arm Morbidity Using Ultrasound Scalpel in Axillary Dissection for Breast Cancer: A Retrospective Analysis.

BACKGROUND: We aimed to assess whether the use of the harmonic scalpel (HS) in axillary dissection would reduce long-term shoulder-arm morbidity compared to traditional instruments (TIs). MATERIALS AND METHODS: A retrospective analysis on 180 patients who underwent standard axillary dissection for breast cancer between 2007 and 2015 was carried out. All patients were evaluated for postoperative pain, impairment of shoulder-arm mobility, seroma formation in axilla, frozen shoulder, and lymphedema. RESULTS: HS procedure on average was 50% shorter compared to the TI technique. HS reduced by 4.5 times the risk of axillary seroma. TIs were associated with 4 times higher risk of developing a painful frozen shoulder. CONCLUSIONS: Use of the HS was associated with reduced costs and a positive long-term effect on shoulder-arm morbidity. Axillary seromas are not the only reason of later postoperative shoulder-arm morbidity: other mechanisms are hypothesized in the onset of this very disabling disorder.

Does a fixed offset hemiarthroplasty implant have any effect on pain and function in patients with a femoral neck fracture?

INTRODUCTION: Hip hemiarthroplasty is the commonest operation performed for a displaced intracapsular hip fracture in the UK. A variety of implants including fixed offset prostheses are utilised. There has been no study investigating the relationship between restoration of femoral offset and long term pain and function. This study aims to evaluate long-term pain and functional outcomes of a fixed offset hemiarthroplasty implant (the Exeter trauma system). PATIENTS AND METHODS: All patients were retrospectively reviewed from a prospectively collected database. In all, 338 patients met the criteria for evaluation. Patients native offset were calculated from the contralateral hip. Pain and functional outcomes were assessed using validated outcome measures. RESULTS: There were no differences found across a range of natural offsets for long-term pain and functional recovery. CONCLUSION: Our experience with the Exeter trauma system suggests that a 40 mm offset implant is a good standard offset to use.

Medication, equipment, and supply costs for common interventions providing extended post-surgical analgesia following total knee arthroplasty in US hospitals.

AIMS: To estimate the cost to hospitals of materials (i.e. medications, equipment, and supplies) required to administer common interventions for post-surgical analgesia after total knee arthroplasty (TKA), including single-injection peripheral nerve block (sPNB), continuous peripheral nerve block (cPNB), periarticular infiltration of multi-drug cocktails, continuous epidural analgesia, intravenous patient-controlled analgesia (IV PCA), and local infiltration of bupivacaine liposome injectable suspension (BLIS). MATERIALS AND METHODS: This analysis was conducted using a mixed methods approach combining published literature, publicly available data sources, and administrative data, to first identify the materials required to administer these interventions, and then estimate the cost to the hospital of those materials. Medication costs were estimated primarily using the Wholesale Acquisition Costs (WAC), the cost of reusable equipment was obtained from published sources, and costs for disposable supplies were obtained from the US Government Services Administration (GSA) database. Where uncertainty existed about the technique used when administering these interventions, costs were calculated for multiple scenarios reflecting different assumptions. RESULTS: The total cost of materials (i.e. medications, equipment, and supplies) required to provide post-surgical analgesia was $41.88 for sPNB with bupivacaine; $756.57 for cFNB with ropivacaine; $16.38 for periarticular infiltration with bupivacaine, morphine, methylprednisolone, and cefuroxime; $453.84 for continuous epidural analgesia with fentanyl and ropivacaine; $178.94 for IV PCA with morphine; and $319.00 for BLIS. LIMITATIONS: This analysis did not consider the cost of healthcare providers required to administer these interventions. In addition, this analysis focused on the cost of materials and, therefore, did not consider aspects of relative efficacy or safety, or how the choice of intervention for post-surgical analgesia might impact outcomes such as length of stay, re-admissions, discharge status, adverse events, or total hospitalization costs. CONCLUSIONS: This study provided an estimate of the costs to hospitals for materials required to administer commonly used interventions for post-surgical analgesia after TKA.

Outcome of In Situ Septoplasty and Extracorporeal Subtotal Septal Reconstruction in Crooked Noses: A Randomized Self-Controlled Study.

IMPORTANCE: Severe dorsal deviations in crooked noses are treated by either in situ septoplasty with asymmetric spreader grafts (ISS) or extracorporeal subtotal septal reconstruction (ECS). To our knowledge, except one retrospective study, there is no other that compares the objective and subjective results of these two treatment modalities. OBJECTIVE: The aim of this study was to compare the aesthetic and functional outcomes of ECS and ISS in crooked noses. DESIGN, SETTING AND PARTICIPANTS: This study was carried out on 40 patients (ISS in 20 patients and ECS in 20 patients) who underwent external rhinoplasty surgery due to crooked noses between May 2014 and January 2016. While performing rhinoplasty on the patients, the decision of whether to use the ECS or ISS technique was randomized in a sequential fashion. MAIN OUTCOMES AND MEASURES: Surgical outcomes were assessed and compared using the anthropometric measurement of photographs with Rhinobase software. Subjective assessments of nasal obstruction and aesthetic satisfaction were evaluated with a visual analog scale. RESULTS: There was a significant difference between rhinion deviation angle, supratip deviation angle (SDA) and tip deviation angle pre- and postoperatively in the ECS group, whereas in the ISS group, except SDA, all other postoperative angles were significantly improved from preoperative values (p = 0.218). The nasal tip projection in the ECS and ISS groups was 29.48, 31.5 preoperatively and 29.78, 31.26 postoperatively. The mean postoperative nasal tip projection value (p > 0.005) did not change significantly compared to the preoperative value in both groups. The mean postoperative value of nasolabial (p = 0.226) angle did not change significantly compared to the mean preoperative one in the ECS group. However, in the ISS group, the mean postoperative value of nasolabial (p = 0.001) angle significantly improved compared to the mean preoperative value. There was significant improvement in both groups, while improvements in both functional and aesthetic outcomes were much higher in the extracorporeal group. None of the patients had postoperative nasal obstruction that required revision surgery. One patient underwent revision rhinoplasty due to an irregularity on the nasal dorsum in the ECS group. CONCLUSIONS AND RELEVANCE: This is the first study that compares subjective and objective aesthetic and functional outcomes of crooked nose surgery according to two common septoplasty techniques in a randomized self-controlled fashion. This study was effective in both objectively and subjectively comparing the functional and aesthetic aspect of the patients submitted to two common different techniques of treatment of nasal deviations in crooked nose patients.

Trainees as Agents of Change in the Opioid Epidemic: Optimizing the Opioid Prescription Practices of Surgical Residents.

OBJECTIVE: Opioid abuse has become an epidemic in the United States, causing nearly 50,000 deaths a year. Postoperative pain is an unavoidable consequence of most surgery, and surgeons must balance the need for sufficient analgesia with the risks of overprescribing. Prescribing narcotics is often the responsibility of surgical residents, yet little is known about their opioid-prescribing habits, influences, and training experience. DESIGN: Anonymous online survey that assessed the amounts of postoperative opioid prescribed by residents, including type of analgesia, dosage, and number of pills, for a series of common general surgery procedures. Additional questions investigated influences on opioid prescription, use of nonnarcotic analgesia, degree of engagement in patient education on opioids, and degree of training received on analgesia and opioid prescription. SETTING: Accreditation Council for Graduate Medical Education accredited general surgery program at a university-based tertiary hospital. PARTICIPANTS: Categorical and preliminary general surgery residents of all postgraduate years. RESULTS: The percentage of residents prescribing opioids postprocedure ranged from 75.5% for incision and drainage to 100% for open hernia repair. Residents report prescribing 166.3 morphine milligram equivalents of opioid for a laparoscopic cholecystectomy, yet believe patients will only need an average of 113.9 morphine milligram equivalents. The most commonly reported influences on opioid-prescribing habits include attending preference (95.2%), concern for patient satisfaction (59.5%), and fear of potential opioid abuse (59.5%). Only 35.8% of residents routinely perform a narcotic risk assessment before prescribing and 6.2% instruct patients how to properly dispose of excess opioids. More than 90% of residents have not had formal training in best practices of pain management or opioid prescription. CONCLUSION AND RELEVANCE: Surgical trainees are relying almost exclusively on opioids for postoperative analgesia, often in excessive amounts. Residents are heavily influenced by their superiors, but are not receiving formal opioid-prescribing education, pointing to a great need for increased resident education on postoperative pain and opioid management to help change prescribing habits.

Longitudinal Perioperative Pain Assessment in Head and Neck Cancer Surgery.

OBJECTIVE: To evaluate perioperative pain in patients undergoing major head and neck cancer surgery and identify associations between preoperative and postoperative pain characteristics. METHODS: Patients undergoing head and neck surgery with regional/free tissue transfer were enrolled. Preoperative pain and validated screens for symptoms (neuropathic pain, anxiety, depression, fibromyalgia) were assessed. Postoperatively, patients completed a pain diary for 4 weeks. RESULTS: Twenty-seven patients were enrolled. Seventy-eight percent had pain prior to surgery, and for 38%, the pain had neuropathic characteristics. Thirteen patients (48%) completed at least 2 weeks of the postoperative pain diary. Patients with moderate/severe preoperative pain report significantly greater pain scores postoperatively, though daily pain decreased at a similar linear rate for all patients. Patients with more severe preoperative pain consumed greater amounts of opioids postoperatively, and this correlated with daily postoperative pain scores. Patients who screened positive for neuropathic pain also reported worse postoperative pain. CONCLUSION: Longitudinal perioperative pain assessment in head and neck patients undergoing surgery suggests that patients with worse preoperative pain continue to endorse worse pain postoperatively and require more narcotics. Patients with preoperative neuropathic pain also report poor pain control postoperatively, suggesting an opportunity to identify these patients and intervene with empiric neuropathic pain treatment.

Quantitative assessment of the impacts of stoppa repair and total extraperitoneal repair on the lower extremity muscular functions in cases of unilateral inguinal hernia: a randomized controlled study.

PURPOSE: Choosing the best operative technique for unilateral inguinal hernia is a challenge for surgeons. Therefore, anticipating loss of strength in the lower extremity muscles could be the initial step to make the right decision. To this end, this prospective randomized controlled study compared the physical activity parameters of the lower extremity muscles in patients who underwent total extraperitoneal repair (TEP) and Stoppa repair. METHODS: Fifty patients with unilateral inguinal hernia who were 18-65 years of age were admitted to a single institution in a metropolitan city in Turkey. Patients were randomized in a 1:1 ratio to parallel study arms of TEP and STOPPA repair. They were evaluated in the preoperative period and on the postoperative day 3 for an objective isometric and isokinetic assessment of the pain-related functional changes in the lower extremity muscles. RESULTS: The measurement results obtained with the Cybex device on the postoperative day 3 were presented as numeric parameters in the digital setting, where the Stoppa repair resulted in a higher loss of strength in the lower extremities compared to the TEP repair. With respect to the total workforce loss in isokinetic muscular measurements at 90 °C/s extension, 90 °C/s flexion, 180 °C/s extension and 180 °C/s flexion, the difference between the TEP repair and Stoppa repair was statistically significant in favor of TEP repair (p < 0.05). CONCLUSION: This study is the first comparative study in the literature to demonstrate the favorable impact of the laparoscopic hernia repair on the physical activity on the same anatomic site compared to the open surgical procedure by using quantitative values. TRIAL REGISTRATION: Clinicaltrials.gov ID: NCT02813057.

Functional and structural assessment of patients with and without persistent pain after thoracotomy.

BACKGROUND: Persistent pain is frequent after thoracotomy, with a reported prevalence of up to 60%. It remains unclear why some patients develop pain, whereas others do not. We therefore examined patients with and without pain after thoracotomy to identify pathophysiological contributors to persistent pain. METHODS: Twenty patients with persistent pain, 12 patients without pain and 20 healthy controls underwent detailed functional and structural assessment including psychometric and neuropathic pain questionnaires, bedside examination for pinprick hyperalgesia and brush allodynia, quantitative sensory testing according to the protocol of the German Research Network on Neuropathic Pain, measurement of capsaicin-evoked flare response, intradermal nerve density as determined by skin biopsies and laser- and heat-evoked potentials. RESULTS: Bedside testing revealed evoked pain in 16 of 20 patients with pain, but only in 2 of 12 patients without pain (p < 0.001). Quantitative sensory testing showed increased mechanical pain sensitivity (p = 0.018) on the operated side in patients with pain, but there were no differences between the two patient groups with regard to intradermal nerve fibre density, area and flux following capsaicin application and laser- and heat-evoked potentials. CONCLUSION: Different and individual pathophysiological mechanisms of pain may obscure the clinical picture and thus preclude identification of a specific pain profile in patients with persistent post-thoracotomy pain. SIGNIFICANCE: Evoked pain is more frequent in patients with pain. Assessment of intradermal nerve density, capsaicin-induced flare response and contact and laser heat-evoked potentials revealed no differences between pain patients and pain-free patients.

Assessment of intraoperative pain during Mohs micrographic surgery (MMS): An opportunity for improved patient care.

BACKGROUND: Intraoperative pain during Mohs micrographic surgery (MMS) has not been characterized. However, many patients report postoperative pain on the day of MMS. OBJECTIVE: We sought to determine if patients experience pain during their MMS visit. METHODS: In phase I of this study, patients were asked to report intraoperative pain level using the verbal numerical rating scale (0-10) at discharge. In phase II, pain levels were assessed before each Mohs layer and at discharge, to determine whether pain was experienced throughout the day. RESULTS: Pain was reported at some point during the MMS day for 32.8% of patients (n = 98). The mean pain number reported was 3.7 (range 1-8) out of 10. Pain was more commonly reported by patients who spent a longer time in the office, had 3 or more Mohs layers, and had a flap or graft repair. Patients most frequently reported pain with surgical sites of the periorbital area and nose. LIMITATIONS: Time between Mohs layers was not measured. There was nonstandardized use of intraoperative local anesthesia volume and oral pain medications. CONCLUSION: Some patients experience pain during MMS. However, the majority of patients report a low level of pain. Additional preventative measures could be considered in patients at higher risk.

Adductor Canal Block With Bupivacaine Liposome Versus Ropivacaine Pain Ball for Pain Control in Total Knee Arthroplasty: A Retrospective Cohort Study.

BACKGROUND: Appropriate postoperative pain control following total knee arthroplasty is important in patient recovery. Adductor canal block (ACB) is a novel method to deliver anesthesia. There are currently no studies using bupivacaine liposome with ACB while also taking into account cost. OBJECTIVE: To compare the efficacy and cost of using bupivacaine liposome to ropivacaine pain ball (RPB) for postsurgical pain control in total knee replacement surgery. The primary efficacy endpoint is mean pain score. Secondary endpoints include opioid and nonopioid pain medication consumption and cost per patient case. METHODS: This was a retrospective, matched cohort study with data collected from electronic medical records from February 2013 to June 2014. Mean pain score was measured by the 11-point Visual Analogue Scale over a 72-hour period. Cost analysis was also done looking at medication, direct, indirect, and total cost per patient case. RESULTS: Mean pain score over the 72 hours was 3.24 in the bupivacaine liposome group compared with 3.83 in the RPB group (P < 0.001). Lower mean pain scores were found in the bupivacaine liposome group during the first 36-hour interval postsurgery (3.1 vs 4.0, respectively, P < 0.001). Mean total cost was $20,919.53 with bupivacaine liposome versus $22,574.17 with RPB (P = 0.03). CONCLUSION: Liposomal bupivacaine demonstrated statistically significant impact in pain control in the first 36 hours, but by the end of the 72-hour interval, it was comparable to RPB in postoperative pain management. Using bupivacaine liposome did provide direct and total cost savings compared with RPB.

An Assessment of Patient Comfort and Morbidity After Robot-Assisted Radical Prostatectomy with Suprapubic Tube Versus Urethral Catheter Drainage.

OBJECTIVE: Robot-assisted laparoscopic prostatectomy (RALP) with suprapubic tube (SPT), compared to urethral catheter (UC) drainage, has been proposed to improve patient comfort and recovery. We sought to compare short-term outcomes for pain and morbidity after RALP with SPT vs UC drainage. METHODS: Between August 2012 and 2014, 159 men underwent a RALP and prospectively completed a questionnaire addressing postoperative pain and satisfaction. Group 1 (n = 94) underwent a RALP by one surgeon who placed a UC and removed it between postoperative day (POD) 7 and 10. Group 2 (n = 65) underwent a RALP by a different surgeon who placed an SPT and UC. On POD 1, the UC was removed. On POD 9, the SPT was capped and removed on POD 11 if the patient was voiding adequately. Preoperative and intraoperative data, complications, questionnaires, and patient-reported morbidity, including unplanned telephone calls and emergency department (ED) visits, were compared between groups. RESULTS: Patient characteristics were similar between groups. One week after surgery, the penile pain score was statistically significantly lower in Group 2 compared to Group 1 (56.9% and 79.8%, respectively, reported minimal-to-moderate pain, p = 0.003). Bladder spasms and overall pain were not significantly higher for Group 1 compared to Group 2 (p > 0.05). When asked "How big a problem has your urine storage device been?," 20.2% of patients in Group 1 reported it as a "moderate-to-big" problem compared to 10.8% in Group 2 (p > 0.05). The number of catheter-related unplanned telephone encounters did not differ between the two groups (p = 0.7), however, although not statistically significant, 4.6% of patients in Group 2 presented to the ED with catheter-related issues (p = 0.07). CONCLUSION: SPT after RALP was associated with less penile pain compared to UC drainage, and modestly better patient satisfaction. There were no significant differences in bladder spasms, overall pain, and patient-reported morbidity between groups.

Postoperative pain assessment in children: a pilot study of the usefulness of the analgesia nociception index.

BACKGROUND: The ability to perform objective pain assessment is very important in paediatric patients. The goal of this study was to investigate the relationship between the analgesia nociception index (ANI), which is based on the heart rate variability, and objective measurements of pain intensity in young or cognitively impaired children, after surgical or imaging procedures (control group) under general anaesthesia. METHODS: On arrival in the recovery room and subsequently at 5-10 min intervals, the level of pain was rated using the FLACC pain scale (0-10). The ANI values (0-100; 0 indicating the worst pain) were recorded simultaneously. The area under the receiver operating characteristic curve (AUC) and grey zone approach were used to evaluate the performance of the ANI to detect patients with FLACC >4. Instantaneous ANI values were compared with ANI values averaged over 256 s periods of time. RESULTS: All children in the surgical group (n=32) developed moderate-to-severe pain (FLACC >4). Children in the control group (n=30) exhibited minimal pain. Instantaneous ANI values were lower in children of the surgical group than in the control group [52 (sd16) vs 69 (16), P<0.001]. The AUC for the 256 s ANI recording period [0.94 (95% confidence interval 0.85-0.99)] was significantly higher than for instantaneous ANI (P<0.05). When measured for a period of 256 s, an ANI cut-off value of 56 (grey zone [58-60]) was most predictive of a FLACC ≥4. CONCLUSIONS: The ANI may provide an objective measurement of acute postoperative pain, which is correlated with that measured on a FLACC scale in young or cognitively impaired children.

A 5-Year Cost-Effectiveness Analysis of Silicone Metacarpophalangeal Arthroplasty in Patients with Rheumatoid Arthritis.

BACKGROUND: There is a paucity of research evaluating the cost-effectiveness of surgical interventions for rheumatoid arthritis patients. Previous reports have challenged the sustainability of improved outcomes after silicone metacarpophalangeal arthroplasty. The authors conducted an economic evaluation of the long-term health outcomes after silicone metacarpophalangeal arthroplasty. METHODS: The authors performed a 5-year prospective cohort study of 170 patients with rheumatoid arthritis (73 surgical and 97 nonsurgical). Objective functional measurements and patient-rated outcomes using the Michigan Hand Outcomes Questionnaire and the Arthritis Impact Measurement Scale 2 were collected at 3 and 5 years. A cost-effectiveness analysis using direct costs from Medicare outpatient claims data (2006 to 2010) was performed to estimate the incremental cost-effectiveness ratios for both the Michigan and Arthritis Impact Measurement Scale 2 measurements. RESULTS: At 5 years, the authors observed a statistically significant difference in upper extremity outcomes (Michigan Hand Outcomes Questionnaire) between the two groups, with surgical patients having higher outcomes. Costs associated with improved outcomes 5 years after surgery were $787 to $1150 when measured by the Michigan Hand Outcomes Questionnaire and $49,843 to $149,530 when measured by the Arthritis Impact scale. The incremental cost-effectiveness ratios did not substantially increase with their observed surgical revision rate of 5.5 percent (approximately 4 percent increase in incremental cost-effectiveness ratio) or with previously published long-term revision rates of 6.2 percent (approximately 6 percent increase in incremental cost-effectiveness ratio). CONCLUSIONS: Short-term improvements in upper extremity outcomes after silicone metacarpophalangeal arthroplasty are maintained over the 5-year follow-up period. These outcomes are achieved at a relatively low cost, even with the addition of potential surgical complications.

HEDEN Pain Scale: A Shortened Behavioral Scale for Assessment of Prolonged Cancer or Postsurgical Pain in Children Aged 2 to 6 Years.

Few observational scales are available for assessing chronic or recurrent pain in children with cancer because overt behavioral signs of chronic pain dissipate as time passes, making them difficult to detect reliably. The Douleur Enfant Gustave Roussy (DEGR) scale developed by Gauvain-Piquard to monitor prolonged pain in children with cancer aged 2-6 years is currently the only validated tool available for this purpose, but is time consuming and difficult to use in daily clinical practice. To shorten composite measurement scales, we developed the Hétero Evaluation Douleur Enfant (HEDEN) scale from the DEGR scale. We present here the process and validation of this scale. Expert consensus was used for the elaboration of HEDEN: 5/10 DEGR items were chosen with three rating levels. Concurrent validity was tested in a first cohort with correlation analysis between HEDEN and DEGR. The HEDEN scale was then validated in a second cohort. In the first step, the study (59 children) showed acceptable correlation between DEGR and HEDEN (r = 0.5), with good reliability (α = 0.61), and interrater agreement (r = 0.62). Subsequent validation in 48 children showed a significant correlation between DEGR and HEDEN (r = 0.6). Reliability was good (α = 0.75), with excellent interrater agreement [r = 0.67 (95% CI: 0.48-0.79)]. On average, the evaluation took 23 minutes (SD = 10.4) for DEGR versus 4.42 minutes (SD = 5.9) for HEDEN. This study shows a good correlation between HEDEN and DEGR scales. HEDEN allows accurate assessment of prolonged pain in young children with cancer.

The assessment of outcome after total knee arthroplasty: are we there yet?

The routine use of patient reported outcome measures (PROMs) in evaluating the outcome after arthroplasty by healthcare organisations reflects a growing recognition of the importance of patients' perspectives in improving treatment. Although widely embraced in the NHS, there are concerns that PROMs are being used beyond their means due to a poor understanding of their limitations. This paper reviews some of the current challenges in using PROMs to evaluate total knee arthroplasty. It highlights alternative methods that have been used to improve the assessment of outcome.

Oriental nose elongation using an L-shaped polyethylene sheet implant for combined septal spreading and extension.

BACKGROUND: The currently recommended strategies for short nose elongation were designed primarily for the Caucasian nasal framework. For Oriental patients, more elongation often is required because a hypoplastic septal cartilage requires more elongation, resulting in a higher risk of complications. This report proposes a modified technique for Oriental nose elongation, which adjusts the pressure points after nasal elongation using an L-shaped implant. METHODS: Between January 2007 and December 2009, 58 patients underwent Oriental nose elongation using an L-shaped, porous, high-density polyethylene sheet implant. Augmentation rhinoplasty and conchal cartilage shield grafts were performed depending on the nasal shape. Pre- and postoperative nasal length, height, and projection as well as columella-labial angle, columella-lobular angle, and nasal tip angle were measured and compared. A patient satisfaction survey was performed postoperatively. All occurring complications were recorded. RESULTS: The postoperative nasal length was significantly elongated from 47.0±10.4 mm to 49.3±10.1 mm (p=0.003), and the nasal height increased significantly from 48.5±9.1 mm to 50.4±8.5 mm (p=0.011). The initially obtuse columella-labial angle improved significantly from 100.8°±12.1° to 92.5°±15.5° (p=0.014). No significant changes were found regarding nasal projection, nasal tip angle, or columella-lobular angle. The majority of the patients (91.3%) were highly satisfied or satisfied with the aesthetic results. A major complication in terms of implant exposure was observed in one case. The minor complications included stiffness of the nasal tip (3 patients) and tip redness (1 patient). CONCLUSIONS: In Oriental nose elongation, the use of an L-shaped graft is a feasible and safe treatment option that allows for an excellent aesthetic outcome and reduces the incidence of complications.

Radiofrequency ablation as first-line treatment of varicose veins.

Endovascular radiofrequency ablation is a minimally invasive method to safely treat symptomatic refluxing varicose veins. A retrospective chart review was used to determine patient demographics, disease severity, treatment algorithm, and outcome in patients who underwent radiofrequency ablation of symptomatic refluxing veins that had failed conservative management. Statistical analysis was done using GraphPad Demo Version (San Diego, CA). Two hundred forty-one limbs in 179 patients (average age, 53 years; 73% females, 27% males) were treated. Preprocedure Clinical Etiological Anatomic and Pathologic (CEAP) scores were C2s: 236, C3s: 4, and C5s:1. Procedures were performed in the office using tumescent anesthetic; all patients could ambulate immediately after the procedure. Postprocedure total occlusion (TO) rate was seen in 93 per cent of limbs (223 limbs) at 3 months and 91 per cent of limbs (220 limbs) at 12 months posttreatment. No relationship was found between patients who did not have total occlusion and age, sex, diameter of veins, CEAP scores, preoperative reflux time, and volume of tumescent anesthetic (P > 0.05). The VNUS procedure is an in-office, minimally invasive procedure with a low complication rate and quick recovery. Total occlusion rates are high and there is improvement in disease severity after treatment.
