Journal of Rehabilitation Medicine Jun 2024To explore and characterize somatosensory dysfunction in patients with post-polio syndrome and chronic pain, by conducting examinations with Quantitative Sensory Testing.
OBJECTIVE
To explore and characterize somatosensory dysfunction in patients with post-polio syndrome and chronic pain, by conducting examinations with Quantitative Sensory Testing.
DESIGN
A cross-sectional, descriptive, pilot study conducted during 1 month.
SUBJECTS/PATIENTS
Six patients with previously established post-polio syndrome and related chronic pain.
METHODS
All subjects underwent a neurological examination including neuromuscular function, bedside sensory testing, a thorough pain anamnesis, and pain drawing. Screening for neuropathic pain was done with 2 questionnaires. A comprehensive Quantitative Sensory Testing battery was conducted with z-score transformation of obtained data, enabling comparison with published reference values and the creation of sensory profiles, as well as comparison between the study site (more polio affected extremity) and internal control site (less affected extremity) for each patient.
RESULTS
Derived sensory profiles showed signs of increased prevalence of sensory aberrations compared with reference values, especially Mechanical Pain Thresholds, with significant deviation from reference data in 5 out of 6 patients. No obvious differences in sensory functions were seen between study sites and internal control sites.
CONCLUSION
Post-polio syndrome may be correlated with a mechanical hyperalgesia/allodynia and might be correlated to a somatosensory dysfunction. With lack of evident side-to-side differences, the possibility of a generalized dysfunction in the somatosensory system might be considered.

PURPOSE
The primary aim of this prospective study was to assess the healing rate of scaphoid pseudoarthrosis treated with wrist arthroscopy, olecranon bone graft and anterograde screw fixation. Clinical, radiological outcomes and complications were included as secondary aims.
METHODS
All patients with scaphoid nonunion were selected between January 2017 and December 2022. Inclusion criteria were patients between 18 and 60 years of age, diagnosis of scaphoid pseudoarthrosis, complete clinical patient-reported outcomes (PROs), radiographic measurements, and underwent at least 1-year follow-up. Scaphoid pseudoarthrosis was treated arthroscopically with olecranon bone graft and anterograde screw fixation. Clinical assessment was performed through visual analog scale (VAS) for pain, QuickDASH (disability of the arm, shoulder, and hand) questionnaire, wrist range of motion using a standard goniometer, and grip strength in Kilograms with a Jamar hydraulic hand dynamometer. Clinical relevance was measured with the minimal clinical important difference (MCID) for VAS and QuickDASH. Scapholunate angle was measured. Union was assessed on CT scan.
RESULTS
Seventeen patients were included with a mean follow-up of 17.2 months. Mean age was 30.1 years old and average time from injury to arthroscopic surgery was 11.1 months. At latest follow-up, there was an improvement in VAS pain score and QuickDASH score. Range of motion and grip strength increased at last follow-up. MCID threshold for the VAS and DASH score was reached by 100% and 94.1%, respectively. Union was achieved in 16 patients (94.1%) after a median of 16 weeks (IQR 16-20).
CONCLUSIONS
Arthroscopic treatment of scaphoid pseudoarthrosis with olecranon bone graft and antegrade percutaneous headless compression screw allows a high grade of union and improves in pain and function at short term follow-up. MCID threshold for the VAS and DASH score was reached by 100% and 94.1%, respectively.

INTRODUCTION
Office administration of intradetrusor onabotulinumtoxinA is commonly used to treat overactive bladder. For preprocedure analgesia, either 50 mL 2% intravesical lidocaine instillation for 20 to 30 minutes or 200 mg oral phenazopyridine can be used. Phenazopyridine is associated with shorter appointment times and is noninferior to lidocaine for pain control in this setting. We performed a cost analysis of phenazopyridine vs lidocaine for analgesia before office intradetrusor onabotulinumtoxinA injection for the treatment of idiopathic overactive bladder.
METHODS
A health care sector-perspective cost analysis was performed. The following assumptions were made: (1) similar efficacy of each medication in providing adequate analgesia, (2) similar physician ease of performing the procedure with either analgesic, and (3) similar patient satisfaction with either analgesic. Average cost of medications, adverse reactions, nursing tasks, and office visit time were found in publicly available data. Sensitivity analyses were performed using TreeAge Pro 2021, R1 software.
RESULTS
Phenazopyridine is less costly compared to lidocaine per visit for office intradetrusor onabotulinumtoxinA injection ($827 vs $925). A difference of $98 per procedure provides a total annual cost savings of over $24 million if all procedures are performed with phenazopyridine instead of lidocaine. Sensitivity analysis showed that phenazopyridine remained less costly under most circumstances, and threshold analysis provided exact circumstances under which phenazopyridine is no longer cost saving.
CONCLUSIONS
Phenazopyridine provides cost savings compared to lidocaine for analgesia before office intradetrusor onabotulinumtoxinA injection for the treatment of idiopathic overactive bladder. If adopted by providers nationwide, phenazopyridine may reduce health care spending and minimize office visit time while maintaining patient pain control and satisfaction.

BACKGROUND
Visceral pain occurs commonly following thoracic surgery, but an effective method to relieve visceral pain in thoracic surgery remains controversial. We test the effect of stellate ganglion blocks (SGB) on perioperative visceral pain following video-assisted thoracoscopic surgery (VATS).
METHODS
A prospective, randomized, controlled trial enrolled 77 elderly patients undergoing VATS. Patients were randomized to SGB followed by modified intercostal nerve block (Group S, n=37); or modified intercostal nerve block only (Group C, n=40). Remifentanil 0.02-0.2 μg·kg-1·min-1 was titrated to keep pain threshold index values between 40-65 and maintain mean arterial pressure or heart rate values around 20% of baseline values. Patient-controlled intravenous analgesia with sufentanil was used in the postoperative period. The co-primary outcomes were the perioperative cumulative opioid consumption and pain scores on movement at 24 h after surgery.
RESULTS
Compared with control group, SGB greatly reduced the intraoperative remifentanil consumption[300.00(235.00-450.00)μg versus 710.00(500.00-915.00)μg; P<0.01], with no difference in cumulative sufentanil consumption to 48h post-surgery. There was a statistically significant difference in pain scores on movement at 24h between groups [4.00(3.00-4.00) versus 4.00(3.25-5.00); P=0.01]. Further exploratory analyses showed significant difference for intra-chest pain on movement at 24h [3.00(2.00-3.00) versus 3.00(2.25-4.00); P=0.01]. No significant difference was observed in nausea/vomiting, time to pass flatus and postoperative length of stay.
CONCLUSION
Preoperative stellate ganglion blocks for elderly patients could effectively blunt intraoperative visceral stress and reduce postoperative visceral pain extending 24 h after VATS. This initial finding deserve further investigation.

OBJECTIVE
To construct percutaneous vertebroplasty for predicting osteoporotic vertebral compression fractures (OVCFs) nomogram of residual back pain (RBP) after percutaneous vertebroplasty(PVP).
METHODS
Clinical data of 245 OVCFs patients who were performed PVP from January 2020 to December 2022 were retrospectively analyzed, including 47 males and 198 females, aged from 65 to 77 years old with an average of (71.47±9.03) years old, and were divided into RBP group and non-RBP group according to whether RBP occurred. Gender, age, comorbidities, fracture stage, body mass index (BMI), bone mineral density (BMD), visual analogue scale (VAS), Oswestry disability index (ODI) and other general information were collected; anterior vertebral height (AVH), anterior vertebral height ratio (AVH), anterior vertebral height ratio(AVHR), Cobb angle, intravertebral vacuum cleft (IVC), thoracolumbar fascia (TLF) injury, paravertebral muscle steatosis, injection volume and leakage of bone cement, bone cement dispersion pattern, anterior vertebral height recovery ratio (AVHRR), Cobb angle changes, etc. imaging parameters before operation and 24 h after operation were collected. Univariate analysis was performed to analysis above factors, and multivariate Logistic regression model was used to investigate independent risk factors for postoperative RBP, and Nomogram model was constructed and verified;receiver operating characteristic(ROC) curve and calibration curve were used to determine predictive performance and accuracy of the model, and Hosmer-Lemeshow (H-L) test was used for evaluation. The area under curve (AUC) of ROC was calculated, and Harrell consistency index (C index) was used to evaluate the predictive efficiency of model;decision curve analysis (DCA) was used to evaluate clinical practicability of model.
RESULTS
There were 34 patients in RBP group and 211 patients in non-RBP group. There were no significant differences in gender, age, comorbidities, fracture stage, BMI, BMD, VAS, ODI, AVH, AVHR and Cobb angle between two groups (>0.05). Univariate analysis showed 6 patients occurred IVC in RBP group and 13 patients in non-RBP, the number of IVC in RBP group was higher than that in non-RBP group (=5.400, =0.020);6 patients occuured TLF injury in RBP group and 11 patients in non-RBP group, the number of TLF injury in RBP group was higher than that in non-RBP group (=7.011, =0.008);In RBP group, 18 patients with grade 3 to 4 paraptebral steatosis and 41 patients in non-RBP group, RBP group was higher than non-RBP group (=21.618, <0.001), and the proportion of bone cement mass in RBP group was higher than non-RBP group (=6.836, =0.009). Multivariate Logistic regression analysis showed IVC (=4.974, =0.025), TLF injury (=5.231, =0.023), Goutallier grade of paravertebral steatosis >2 (=15.124, <0.001) and proportion of bone cement (=4.168, =0.038) were independent risk factors for RBP after PVP. ROC curve of model showed AUC of original model was 0.816[OR=2.862, 95%CI (0.776, 0.894), <0.001]. The internal verification of model through 200 bootstrap samples showed the value of C index was 0.936, and calibration curve showed predicted probability curve was close to actual probability curve. H-L goodness of fit test results were =5.796, =0.670. DCA analysis results showed the decision curve was above None line and All line when the threshold value ranged from 6% to 71%.
CONCLUSION
IVC, TLF combined injury, paravertebral muscle steatosis with Goutallier grade> 2, and bone cement diffusion with mass type are independent risk factors for RBP after PVP. The risk prediction model for RBP after PVP established has good predictive performance and good clinical practicability.

Does early exercise intolerance effect time to return to play, symptom burden, neurocognition, Vestibular-Ocular-Motor (VOM) function and academic ability in acutely concussed student-athletes?
INTRODUCTION
Early Exercise Intolerance (EEI) is associated with delayed recovery and longer time to Return To Play (RTP), but this has not been established.Participants; ( = 52, male = 30) UK university-aged rugby-union student-athletes.
METHODS
Student-athletes completed baseline screening (July-October 2021 and 2022). The test battery was repeated within 48 h, 4, 8 and 14 days after a Sports-Related Concussion (SRC) with the Buffalo Concussion Bike or Treadmill Test to set sub-symptom heart rate threshold. Student-athletes then completed a controlled early exercise protocol in-between reassessment (days 3, 5-7 and 9-13). Those with EEI were compared to those with early-exercise tolerance.
OUTCOME MEASURES
Post-Concussion Symptom Scale, Immediate Post-Concussion and Cognitive Test, Vestibular-Ocular Motor Screening Tool and the Revised Perceived Academic Impact Tool.
RESULTS
EEI was seen throughout the initial 14-days post-SRC (23.8%, 22.4%, 25.5%. 25.0%). EEI was associated with a slower reaction time within 48 h (-0.01 (-0.030-0.043) Vs 0.06 (0.033-0.24), = 0.004) and greater VOMS scores within 48 h; (0.00 (0.00-4.00) Vs 5.50 (2.75-9.00), = 0.016) and 4 days (0.00 (0.00-2.00) Vs 5.00 (0.00-6.00), = 0.044). RTP was 12.5 days longer in those with EEI at 14-days post-SRC.
CONCLUSION
EEI is prevalent following an SRC in university-aged student-athletes and was associated with delayed recovery and RTP.

Journal of Dentistry Jun 2024This cohort study aimed to assess the incidence of somatosensory alterations after implant surgery using standardized quantitative and qualitative sensory testing.
OBJECTIVE
This cohort study aimed to assess the incidence of somatosensory alterations after implant surgery using standardized quantitative and qualitative sensory testing.
METHODS
33 participants with single-tooth loss, undergoing immediate implant loading were included. Quantitative Sensory Testing (QST) and Qualitative Sensory Testing (QualST) were conducted at eight time points over a year (baseline to 1 year). Two-Way Repeated Measures ANOVA and post hoc Tukey test were used on QST values and Cochran Q test on QualST.
RESULTS
The study revealed significant increase in thermal thresholds overtime. At the operated side, overall Cold Pain Threshold (extraoral: p = 0.030; intraoral: p < 0.001), and Cold Detection Threshold (intraoral: p < 0.001) increased overtime. In contralateral region, maxilla Cold Detection Threshold (extraoral: p = 0.024; intraoral: p = 0.031), Warm Detection Threshold (extraoral: p = 0.026; intraoral: p = 0.047) and overall Cold Pain Threshold (extraoral and intraoral: p < 0.001) also increased. QualST showed extraoral pinprick (p = 0.032) and intraoral pinprick (p = 0.000), cold (p = 0.000) and touch (p = 0.002) stimuli abnormalities overtime.
CONCLUSIONS
Somatosensory alterations after implant surgery were detected in both quantitative and qualitative sensory assessments, but rapidly decreased during the first follow-ups, and then continuously until 1-year.
CLINICAL SIGNIFICANCE
This study provides clinical and controlled evidence on the real effect of the somatosensory alterations overtime, leading to a better understanding of neurosensory behaviour after single-tooth dental implant rehabilitation.

Journal of Cardiothoracic and Vascular... May 2024This study was designed to compare individualized and conventional hyperglycemic thresholds for the risk of acute kidney injury (AKI) after cardiac surgery.
OBJECTIVES
This study was designed to compare individualized and conventional hyperglycemic thresholds for the risk of acute kidney injury (AKI) after cardiac surgery.
DESIGN
This was an observational study.
SETTING
The study took place in a single-center tertiary teaching hospital.
PARTICIPANTS
Adult patients who underwent cardiac surgery between January 2012 and November 2021 were enrolled.
MEASUREMENTS AND MAIN RESULTS
Two blood glucose thresholds were used to define intraoperative hyperglycemia. While the conventional hyperglycemic threshold (CHT) was 180 mg/dL in all patients, the individualized hyperglycemic threshold (IHT) was calculated based on the preoperative hemoglobin A1c level. Various metrics of intraoperative hyperglycemia were calculated using both thresholds: any hyperglycemic episode, duration of hyperglycemia, and area above the thresholds. Postoperative AKI associations were compared using receiver operating characteristic curves and logistic regression analysis. Among the 2,427 patients analyzed, 823 (33.9%) developed AKI. The C-statistics of IHT-defined metrics (0.58-0.59) were significantly higher than those of the CHT-defined metrics (all C-statistics, 0.54; all p < 0.001). The duration of hyperglycemia (adjusted odds ratio, 1.09; 95% confidence interval, 1.02-1.16) and area above the IHT (1.003; 1.001-1.004) were significantly associated with the risk of AKI, except for the presence of any hyperglycemic episode. None of the CHT-defined metrics were significantly associated with the risk of AKI.
CONCLUSIONS
Individually defined intraoperative hyperglycemia better predicted postcardiac surgery AKI than universally defined hyperglycemia. Intraoperative hyperglycemia was significantly associated with the risk of AKI only for the IHT. Target blood glucose levels in cardiac surgical patients may need to be individualized based on preoperative glycemic status.

Effectiveness and cost-effectiveness of an individualised, progressive walking and education intervention for the prevention of low back pain recurrence in Australia (WalkBack): a randomised controlled trial.
BACKGROUND
Recurrence of low back pain is common and a substantial contributor to the disease and economic burden of low back pain. Exercise is recommended to prevent recurrence, but the effectiveness and cost-effectiveness of an accessible and low-cost intervention, such as walking, is yet to be established. We aimed to investigate the clinical effectiveness and cost-effectiveness of an individualised, progressive walking and education intervention to prevent the recurrence of low back pain.
METHODS
WalkBack was a two-armed, randomised controlled trial, which recruited adults (aged 18 years or older) from across Australia who had recently recovered from an episode of non-specific low back pain that was not attributed to a specific diagnosis, and which lasted for at least 24 h. Participants were randomly assigned to an individualised, progressive walking and education intervention facilitated by six sessions with a physiotherapist across 6 months or to a no treatment control group (1:1). The randomisation schedule comprised randomly permuted blocks of 4, 6, and 8 and was stratified by history of more than two previous episodes of low back pain and referral method. Physiotherapists and participants were not masked to allocation. Participants were followed for a minimum of 12 months and a maximum of 36 months, depending on the date of enrolment. The primary outcome was days to the first recurrence of an activity-limiting episode of low back pain, collected in the intention-to-treat population via monthly self-report. Cost-effectiveness was evaluated from the societal perspective and expressed as incremental cost per quality-adjusted life-year (QALY) gained. The trial was prospectively registered (ACTRN12619001134112).
FINDINGS
Between Sept 23, 2019, and June 10, 2022, 3206 potential participants were screened for eligibility, 2505 (78%) were excluded, and 701 were randomly assigned (351 to the intervention group and 350 to the no treatment control group). Most participants were female (565 [81%] of 701) and the mean age of participants was 54 years (SD 12). The intervention was effective in preventing an episode of activity-limiting low back pain (hazard ratio 0·72 [95% CI 0·60-0·85], p=0·0002). The median days to a recurrence was 208 days (95% CI 149-295) in the intervention group and 112 days (89-140) in the control group. The incremental cost per QALY gained was AU$7802, giving a 94% probability that the intervention was cost-effective at a willingness-to-pay threshold of $28 000. Although the total number of participants experiencing at least one adverse event over 12 months was similar between the intervention and control groups (183 [52%] of 351 and 190 [54%] of 350, respectively, p=0·60), there was a greater number of adverse events related to the lower extremities in the intervention group than in the control group (100 in the intervention group and 54 in the control group).
INTERPRETATION
An individualised, progressive walking and education intervention significantly reduced low back pain recurrence. This accessible, scalable, and safe intervention could affect how low back pain is managed.
