RESUMEN
BACKGROUND Primary lower-extremity hyperhidrosis (PLEH) can be treated by CT-guided lumbar sympathetic nerve modulation using absolute ethanol. However, doses of ethanol that are too high can cause nerve injury, and doses that are too low have suboptimal results. The present study aimed to investigate the dose-effect relationship of CT-guided lumbar sympathetic nerve modulation with absolute ethanol for PLEH. MATERIAL AND METHODS The study was conducted at the First Affiliated Hospital of Jiaxing University between 07/2014 and 02/2017. Twenty participants were enrolled in each group. The doses of absolute ethanol were 2.0 ml in the R1 group, 2.5 ml in the R2 group, 3.0 ml in the R3 group, 3.5 ml in the R4 group, and 4.0 ml in the R5 group. Treatment effectiveness was assessed according to the time to complete hyperhidrosis relief: <10 min, effective; ≥10 min, non-effective. RESULTS The patient characteristics among the 5 groups were not statistically different (P>0.05). The onset time and time to complete hyperhidrosis relief decreased significantly with increasing dose of absolute ethanol (P<0.05). The effective rates in the 5 groups were 15.0%, 35.0%, 60.0%, 90.0%, and 100.0%, respectively. The ED50 and ED95 were 2.306 ml (95% CI: 2.003-2.512 ml) and 3.343 ml (95% CI: 3.051-3.962 ml), respectively. CONCLUSIONS This was the first dose-effect pilot study of consecutive PLEH patients treated by CT-guided lumbar sympathetic nerve modulation. CT-guided lumbar sympathetic nerve modulation with 2.306 ml (ED50) and 3.343 ml (ED95) of absolute ethanol showed treatment efficacy for PLEH. No complications were seen.

Purpose: To evaluate the clinical outcomes for arthroscopic treatment of acute posterior cruciate ligament (PCL) avulsion fractures with adjustable-loop cortical button fixation device. Methods: Patients with PCL tibial avulsion fractures treated with an adjustable-loop cortical button fixation device between October 2019 and October 2020 were retrospectively identified. Patients with type 1 were treated using plaster fixation as a conservative treatment, whereas patients with type 2 and 3 with displacement were treated using an arthroscopic adjustable-loop cortical button. Operating time, incision recovery, complications, and postoperative fracture healing time were monitored. All patient follow-up was done at 12 months' postoperatively. Lysholm Knee Score and the International Knee Documentation Committee score were used to assess knee function. Results: A total of 30 patients were included in the study (20 male/10 female; mean age 45.5 years, range 35-68 years). The mean operative time was 67.5 minutes (range: 50-90 minutes). The postoperative incision healed at stage A without complications, such as medically induced vascular nerve injury, intra-articular hematoma, or infection. All 30 patients were tracked postoperatively for 12 to 14 months, with a mean follow-up period of 12.6 months. The Lysholm knee function score was 45.93 ± 6.15 before surgery and 87.10 ± 3.71 at 12 months after surgery, and the International Knee Documentation Committee score was 19.27 ± 4.40 before surgery and 95.47 ± 1.87 at 12 months after surgery, with a statistically significant difference. Conclusions: The treatment of PCL avulsion fractures with arthroscopic adjustable-loop cortical button fixation is easy to perform and shows good clinical results in our study. Level of Evidence: IV, therapeutic case series.
RESUMEN
STUDY DESIGN: Retrospective case-control study. OBJECTIVE: To explore the association of early postoperative nadir hemoglobin with risk of a composite outcome of anemia-related and other adverse events. METHODS: We retrospectively analyzed data from spinal tumor patients who received intraoperative blood transfusion between September 1, 2013 and December 31, 2020. Uni- and multivariate logistic regression was used to explore relationships of clinicodemographic and surgical factors with risk of composite in-hospital adverse events, including death. Subgroup analysis explored the relationship between early postoperative nadir hemoglobin and composite adverse events. RESULTS: Among the 345 patients, 331 (95.9%) experienced early postoperative anemia and 69 (20%) experienced postoperative composite adverse events. Multivariate logistic regression analysis showed that postoperative nadir Hb (OR = .818, 95% CI: .672-.995, P = .044), ASA ≥3 (OR = 2.007, 95% CI: 1.086-3.707, P = .026), intraoperative RBC infusion volume (OR = 1.133, 95% CI: 1.009-1.272, P = .035), abnormal hypertension (OR = 2.199, 95% CI: 1.085-4.457, P = .029) were correlated with composite adverse events. The lumbar spinal tumor was associated with composite adverse events with a decreased odds compared to thoracic spinal tumors (OR = .444, 95% CI: .226-.876, P = .019). Compared to patients with postoperative nadir hemoglobin ≥11.0 g/dL, those with nadir <9.0 g/dL were at significantly higher risk of postoperative composite adverse events (OR = 2.709, 95% CI: 1.087-6.754, P = .032). CONCLUSION: Nadir hemoglobin <9.0 g/dL after spinal tumor surgery is associated with greater risk of postoperative composite adverse events in patients who receive intraoperative blood transfusion.
RESUMEN
Background: Previous observational studies have shown that low back pain (LBP) often coexists with sleep disturbances, however, the causal relationship remains unclear. In the present study, the causal relationship between sleep disturbances and LBP was investigated and the importance of sleep improvement in the comprehensive management of LBP was emphasized. Methods: Genetic variants were extracted as instrumental variables (IVs) from the genome-wide association study (GWAS) of insomnia, sleep duration, short sleep duration, long sleep duration, and daytime sleepiness. Information regarding genetic variants in LBP was selected from a GWAS dataset and included 13,178 cases and 164,682 controls. MR-Egger, weighted median, inverse-variance weighted (IVW), penalized weighted median, and maximum likelihood (ML) were applied to assess the causal effects. Cochran's Q test and MR-Egger intercept were performed to estimate the heterogeneity and horizontal pleiotropy, respectively. Outliers were identified and eliminated based on MR-PRESSO analysis to reduce the effect of horizontal pleiotropy on the results. Removing each genetic variant using the leave-one-out analysis can help evaluate the stability of results. Finally, the reverse causal inference involving five sleep traits was implemented. Results: A causal relationship was observed between insomnia-LBP (OR = 1.954, 95% CI: 1.119-3.411), LBP-daytime sleepiness (OR = 1.011, 95% CI: 1.004-1.017), and LBP-insomnia (OR = 1.015, 95% CI: 1.004-1.026), however, the results of bidirectional MR analysis between other sleep traits and LBP were negative. The results of most heterogeneity tests were stable and specific evidence was not found to support the disturbance of horizontal multiplicity. Only one outlier was identified based on MR-PRESSO analysis. Conclusion: The main results of our research showed a potential bidirectional causal association of genetically predicted insomnia with LBP. Sleep improvement may be important in comprehensive management of LBP.
RESUMEN
BACKGROUND: Postoperative pain management in breast surgery and video-assisted thoracic surgeries (VATS) remains challenging. Oral or intravenous infusion of opioids were early treatments, but they can result in gastrointestinal reactions, respiratory inhibition, and other adverse reactions. In recent years, various regional block techniques have been employed for postoperative analgesia of these surgeries. However, a pair-wise meta-analysis cannot comprehensively rank and evaluate the analgesic effects and adverse events of various regional blocks. OBJECTIVE: The purpose of this network meta-analysis (NMA) was to compare the analgesic effects and adverse events of different regional block techniques after breast surgery and VATS. STUDY DESIGN: NMA of randomized controlled trials (RCTs) for comparing multiple regional block techniques in breast surgery and VATS. METHODS: Pubmed, Embase, and Cochrane databases were searched systematically for RCTs comparing analgesic effects and adverse events after breast surgery and VATS. After critical appraisal, a random-effects NMA was mainly used to compare all the regional blocks' analgesic effects and adverse events. The Population, Interventions, Comparators, Outcomes, and Study design (PICOS) framework was used to build the search strategies and present the results according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The primary endpoint was opioid consumption within 24 hours after the operation; secondary endpoints included dynamic and static pain scores and the incidence of nausea and vomiting. This study is registered in the Prospective Register of Systematic Reviews (PROSPERO) with a PROSPERO number of CRD42021283907. RESULTS: A total of 21 clinical trials, including 1,284 patients and 6 different regional block techniques (paravertebral block pectoral nerve block serratus anterior plane block [SAPB], intercostal nerve block [ICNB], erector spinal plane block and thoracic epidural anesthesia), were included and analyzed. There was no significant difference between the consistent and the inconsistent models. Based on limited evidence, SAPB may be the most effective regional block technique for relieving postoperative pain, while ICNB had the lowest probability of nausea and vomiting. There was no significant difference in the pair-wise comparisons. In this study, we found no obvious publication bias. LIMITATIONS: Limitations include: morphine milligram equivalents were not used to calculate opioid consumption; the scales used in the studies were different; the number of studies and total sample size included was limited; non-English literature and gray literature were not included; more databases were not searched. CONCLUSIONS: After a comprehensive evaluation of postoperative analgesic effects and adverse events based on the NMA, we hypothesize that SAPB and ICNB have distinct advantages in postoperative analgesia and reduce the incidence of nausea and vomiting, respectively. However, conclusions drawn from more RCTs may be more convincing.

OBJECTIVE: To analyze the influencing factors of motor dysfunction in patients with limb herpes zoster and to construct a nomogram to predict the risk of this complication. METHODS: A total of 213 patients with limb herpes zoster in the First Hospital of Jiaxing from January 2015 to June 2020 were enrolled. The muscle strength of the affected limb was evaluated by the Medical Research Council (MRC) score. The muscle strength of the affected limb was less than grade 5, and lower than that of the contralateral limb (normal side) was defined as motor dysfunction. Univariate and multivariate logistic regression analyses were used to determine the influencing factors of motor dysfunction in patients with limb herpes zoster. The nomogram of the risk of motor dysfunction was drawn by R software. Discrimination and calibration of the prediction model were assessed by using the C-index and calibration plot. Internal validation was assessed by using bootstrapping validation. RESULTS: There were 58 cases in the motor dysfunction group and 155 cases in the nonmotor dysfunction group, and univariate analysis showed that the location of involvement (OR = 4.095, 95% CI: 2.097-8.466, P = 0.017), whether or not diseases were combined (OR = 0.520, 95% CI: 0.281-0.959, P = 0.036) and the number of affected centrums (OR = 0.336, 95% CI: 0.177-0.632, P = 0.001) were associated with the occurrence of motor dysfunction in patients with limb herpes zoster. Multivariate logistic regression analysis showed that upper limb involvement (OR = 3.811, 95% CI: 1.829-8.387, P = 0.001), noncombined diseases (OR = 0.493, 95% CI: 0.249-0.969, P = 0.041) and the number of affected centrums ≤3 (OR = 0.439, 95% CI: 0.218-0.881, P = 0.020) were independent influencing factors of this complication. The prediction model displayed good discrimination with a C-index of 0.72 and good calibration. A high C-index value of 0.71 could still be reached in the interval validation. CONCLUSION: This study used the clinical data available to establish a nomogram model for motor dysfunction of limb herpes zoster and found that motor dysfunction is more likely to occur in patient who meets upper limb involvement, combined diseases and the number of affected centrums >3. This kind of high-risk group should be intervened as soon as possible.
RESUMEN
BACKGROUND: Primary palm hyperhidrosis (PPH) is a chronic disease characterized by uncontrolled palm-sweating exceeding physiological needs. It negatively impacts the quality of life of the patients and can lead to different degrees of psychological problems. Currently, there are a variety of treatment options for PPH, of which thoracotomy is a first-line treatment that has shown good efficacy. However, since it is an invasive procedure requiring general anesthesia and is often associated with high costs and serious complications, better alternatives should be explored. Computed tomography (CT)-guided percutaneous puncture of radiofrequency thermocoagulation (RF-TC) of the thoracic sympathetic nerve is a promising alternative treatment. It is a minimally invasive procedure that can be performed under local anesthesia and is associated with rapid recovery. However, the factors affecting the duration of the surgery-related benefits and outcomes of CT-guided percutaneous RF-TC of the thoracic sympathetic nerve are unclear. OBJECTIVES: To investigate the factors influencing the outcomes of CT-guided percutaneous RF-TC of the thoracic sympathetic nerve in patients with PPH. STUDY DESIGN: A retrospective study. SETTING: This study was conducted at the Pain Department of Jiaxing University Affiliated Hospital (Jiaxing, China). METHODS: After approval by the Ethics Committee of the Affiliated Hospital of Jiaxing College, the data of 232 corresponding patients were assessed. The Kaplan-Meier method was used for survival analysis. Univariate and multivariate analyses were performed to identify factors associated with PPH and to construct a nomogram for predicting postoperative recurrence. Time-independent receiver operating characteristic (ROC) curve analyses were performed to assess the nomogram's predictive capacity. RESULTS: In the one-year survival analysis model, gender (HR = 1.573, 95%CI: 0.844 to 2.934), age (HR = 0.965, 95%CI: 0.915 to 1.018), disease course (HR = 0.960, 95%CI: 0.908 to 1.015), palm temperature difference (HR = 0.377, 95%CI: 0.287 to 0.495), perfusion index difference (HR = 0.590, 95%CI: 0.513 to 0.680) and hyperhidrosis disease severity scale (HR = 1.963, 95%CI: 0.769 to 5.011) were identified as statistically significant factors in univariate analysis, while palm temperature difference (HR = 0.589, 95%CI: 0.369 to 0.941) and perfusion index difference (HR = 0.357, 95%CI: 0.588 to 0.968) were the independent factors in the multivariate Cox proportional hazards risk model. In the 2-year survival analysis model, palm temperature difference (HR = 0.353, 95%CI: 0.261 to 0.478), perfusion index difference (HR = 0.589, 95%CI: 0.510 to 0.680) and hyperhidrosis disease severity scale (HR = 1.964, 95%CI: 0.771 to 5.006) were the statistically significant factors while palm temperature difference (HR = 0.507, 95%CI: 0.321 to 0.799) and perfusion index difference (HR = 0.789, 95%CI: 0.625 to 0.995) were the independent factors. LIMITATIONS: This single-center retrospective study was limited by its small sample size, short follow-up time, and the possibility of bias resulting from the non-random patient selection. CONCLUSION: Palm temperature difference and perfusion index difference were independent risk factors associated with prolonging the surgical benefits and reducing postoperative recurrence of CT-guided RF-TC of the sympathetic nerves in patients with PPH.

BACKGROUND: Primary trigeminal neuralgia can achieve satisfactory results through clinical treatment and intervention. The pathogenesis of neuralgia caused by varicella-zoster virus infection of the trigeminal nerve is more complex, and it is still difficult to relieve the pain in some patients simply by drug treatment or surgical intervention. CASE SUMMARY: A 66-year-old woman was hospitalized with herpetic neuralgia after herpes zoster ophthalmicus (varicella-zoster virus infects the ophthalmic branch of the trigeminal nerve). On admission, the patient showed spontaneous, electric shock-like and acupuncture-like severe pain in the left frontal parietal region, and pain could be induced by touching the herpes area. The numerical rating scale (NRS) was 9. There was no significant pain relief after pulsed radiofrequency and thermocoagulation of the ophthalmic branch of the trigeminal nerve. Combined with patient-controlled intravenous analgesia (PCIA) with esketamine, neuralgia was significantly improved. The patient had no spontaneous pain or allodynia at discharge, and the NRS score decreased to 2 points. The results of follow-up 2 mo after discharge showed that the NRS score was ≤ 3, and the Pittsburgh Sleep Quality Index score was 5 points. There were no adverse reactions. CONCLUSION: Trigeminal extracranial thermocoagulation combined with esketamine PCIA may be a feasible method for the treatment of refractory herpetic neuralgia after herpes zoster ophthalmicus.
RESUMEN
BACKGROUND: At present, there are many surgical treatments for primary hyperhidrosis (PH), but their medium- and long-term effects remain unclear. OBJECTIVES: To evaluate and compare the efficacy of radiofrequency sympathectomy (RFS) and percutaneous ethanol sympatholysis (PES) in the treatment of PH. STUDY DESIGN: A retrospective study. SETTING: This study was performed at the Affiliated Hospital of Jiaxing University, China. METHODS: Patients who underwent RFS and PES at The First Affiliated Hospital of Jiaxing University for PH were retrospectively reviewed from January 2016 through December 2018 and were divided into an RFS group and a PES group. The Hyperhidrosis Disease Severity Scale was evaluated at the following time points: before the operation, immediately after the operation, 12 months and 24 months after the operation. The effective rate, patient satisfaction, and compensatory hyperhidrosis were also evaluated. RESULTS: A total of 94 patients diagnosed with primary hyperhidrosis were included (RFS group, n = 45; PES group, n = 49). RFS yielded a postprocedure 24-month effective rate of 53.33% in treating hyperhidrosis compared to PES (24.49%, P < 0.05). There were no significant differences between the 2 groups regarding patient satisfaction (P = 0.927) and compensatory hyperhidrosis (P = 0.711). LIMITATIONS: This was a single-center study. CONCLUSION: This is the first clinical study to evaluate the efficacy of RFS and compare it with PES in treating primary hyperhidrosis. RFS significantly decreased hyperhidrosis and had a higher 2-year effective rate compared to PES.

BACKGROUND: There are differences in the clinical treatment schemes for patients with different severities of herpes zoster (HZ). Therefore, effective and accurate evaluation of disease severity is of great significance for the formulation of treatment plans. Postherpetic neuralgia (PHN) with long-term chronic pain leads to anxiety, depression, and even suicidal thoughts, which place a heavy burden on society and the family. Therefore, identifying risk factors and taking early intervention to reduce the occurrence of PHN is meaningful. Electromyography (EMG) can provide technical support for the early diagnosis of peripheral neuropathy. However, the application of EMG in HZ and PHN has rarely been reported. The purpose of this study was to compare the detection indices of EMG in patients with different severities and prognoses of HZ and to analyze the application of EMG in severity and prognosis of HZ. OBJECTIVE: This study aimed to explore the relationship between EMG and severity and prognosis of upper limb HZ. STUDY DESIGN: A retrospective, observational study. SETTING: The study was carried out in the Pain Department of the affiliated Hospital of Jiaxing College in Jiaxing, China. METHODS: A total of 91 patients with upper limb HZ at the First Hospital of Jiaxing between January 2015 and August 2021 were enrolled. The patients were divided into mild, moderate, and severe HZ groups according to their numeric rating scale (NRS) scores. The occurrence of PHN was defined as a poor prognosis. The patients were divided into non-PHN and PHN groups according to the occurrence of PHN. Motor and sensory conduction indices of the median nerve were measured in each group. Spearman's correlation analysis was used to analyze the relationship between the EMG-related data of the median nerve and the NRS score and muscle strength. Univariate and multivariate logistic regression analyses were used to determine the independent influencing factors of PHN in patients with upper limb HZ, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of EMG-related data in patients with upper limb HZ. RESULTS: Among 91 patients, there were 29 patients in the mild HZ group, 31 in the moderate HZ group, and 31 in the severe HZ group. The sensory nerve action potential (SNAP) amplitude of the median nerve in the severe and moderate HZ groups was lower than that in the mild HZ group, and that in the severe HZ group was lower than that in the moderate HZ group (F = 22.192, P < 0.05). Through Spearman's correlation analysis, it was found that the compound muscle action potential (CMAP) and SNAP amplitudes of the median nerve on the affected limb were negatively correlated with the NRS score (r = -0.266, P = 0.011; r = -0.778, P < 0.001), and there was no significant correlation between each index and muscle strength (P > 0.05). Among 91 patients, 44 and 47 were in the non-PHN and PHN groups, respectively. Univariate and multivariate logistic regression analyses showed that the CMAP amplitude of the median nerve on the affected limb (OR = 0.241, 95% CI: 0.098-0.567, P = 0.001) and SNAP amplitude (OR = 0.268, 95% CI: 0.110-0.628, P = 0.002) were independent influencing factors of PHN. Through the analysis of the ROC curve, it was found that the CMAP and SNAP amplitudes of the median nerve on the affected limb had a high predictive value for PHN (AUC = 0.657, P = 0.010; AUC = 0.773, P < 0.001). The cutoff values were 5.45 mV and 10.80 mV, respectively; and the predictive value of the 2 indices combined was the highest (AUC = 0.785, P < 0.001). LIMITATIONS: The nonrandomized, single-center, small sample size, and retrospective design are major limitations of this study. CONCLUSION: The CMAP and SNAP amplitudes of the median nerve on the affected limb were related to the degree of pain in patients with upper limb HZ. The CMAP and SNAP amplitudes of the median nerve on the affected limb can be used as prognostic factors for patients with upper limb HZ, and CMAP amplitude combined with SNAP amplitude is more valuable in predicting prognosis.

BACKGROUND: Cold hypersensitivity in the hands and feet (CHHF) is a disease characterized by abnormal cold in the limbs with limited treatment options. Compared to traditional drug therapy, lumbar sympathectomy is a new minimally invasive surgical method for treating CHHF. OBJECTIVES: The present study aimed to compare the efficacy and safety of lumbar sympathetic radiofrequency thermocoagulation (RFT) and chemical lumbar sympathectomy (CLS) in treating CHHF. STUDY DESIGN: A single-center, retrospective, observational study. SETTING: Department of Anesthesiology and Pain Medicine, Jiaxing, China. METHODS: A total of 102 patients with CHHF who underwent lumbar sympathectomy from January 2016 to April 2020 were included in this study. According to the mode of operation, the patients were divided into 2 groups: CLS (n = 56) and RFT (n = 46). All patients were treated under the guidance of computed tomography (CT). The foot temperature (T) and peripheral perfusion index (PI) were compared between the 2 groups before and after treatment. The 2 groups' visual analog scale (VAS) scores were evaluated before the operation and 1 day, 1 month, 3 months, 6 months, and 1 year after the treatment. The postoperative recurrence rate of the 2 groups was observed 1 year after treatment. The short and long-term complications during the postoperative follow-up were recorded. RESULTS: All patients completed the operation successfully. No significant difference was noted in the gender, age, course of the disease, preoperative T and PI, and postoperative T and PI between the 2 groups (P > 0.05). The postoperative T and PI were significantly increased compared to preoperative in both groups (P < 0.05). No significant difference was observed in T and PI between the 2 groups (P > 0.05), and no significant difference was recorded in VAS scores between the 2 groups 1 day and 1 month after the treatment (P > 0.05). The VAS scores at 3 months, 6 months, and 1 year after the treatment were significantly lower in the RFT group compared to the CLS group (P < 0.05). During the 1-year follow-up, patients who received CLS had a higher risk of recurrence than RFT treatment (P < 0.05). The RFT group treatment of CHHF showed better long-term outcomes than the CLS group. About 12.5% of patients in the CLS group and 6.5% in the RFT group had postoperative complications, including pain at the puncture site and genitofemoral neuralgia. However, no severe complications or deaths were observed in either of the 2 groups. LIMITATIONS: The was a single-center, retrospective, non-randomized study, which is a major limitation of this study. CONCLUSIONS: Lumbar sympathetic RFT had better long-term efficacy, lower recurrence, and fewer complications than the chemical lumbar sympathectomy when treating CHHF.

BACKGROUND: Pulsed radiofrequency (PRF) on the dorsal root ganglion (DRG) is a common minimally invasive surgery for herpes zoster (HZ)-related pain, including acute zoster pain and postherpetic neuralgia (PHN); however, some patients still have no obvious pain relief, a high recurrence rate, and short-term recurrence. Radiofrequency thermocoagulation (RF-TC) has a higher temperature; however, it is still unknown whether the degree of complete damage will affect the recurrence rate and if there is any difference compared with the effect of PRF. OBJECTIVES: This study mainly aimed to explore whether there was a difference in the recurrence rate following CT-guided PRF and RF-TC for HZ-related pain. This is also a preliminary exploration of RF-TC for treatment of HZ-related pain. STUDY DESIGN: A retrospective cohort study. SETTING: The study was carried out in the Affiliated Hospital of Jiaxing University in Jiaxing, China. METHODS: We included a total of 134 patients who underwent CT-guided PRF or RF-TC for HZ-related pain in the pain department. Medical records related to relapse, numerical rating scale scores (NRSs), Pittsburgh sleep quality index (PSQI), adverse events, and satisfaction were reviewed. The Kaplan-Meier analysis was used to estimate the cumulative survival rates of the surgical procedures. After controlling for related confounders, the relationship of surgical procedure and recurrence rate was analyzed by interval-censored multivariable Cox regression. A time-independent receiver operating characteristic (ROC) curve analysis confirmed the signature's predictive capacity. A nomogram was used to predict postoperative recurrence. Multiple imputations was used to deal with the randomly missing data. Repeated-measures analysis of variance (ANOVA) was applied to analyze NRSs and PSQI at each time interval, and multiple comparisons were made. RESULTS: In 134 patients with HZ-related pain, the ratio of patients receiving PRF to those receiving RF-TC was 1:1. Interval-censored multivariable Cox regression analysis demonstrated that lesion space (1-2% / ref: adjusted hazard ratio (HR), 2.075; 95% confidence intervals (CI), 1.002-4.210; > 2% / ref: adjusted HR, 3.406; 95% CI, 1.670 - 6.950), pain grade (adjusted HR, 2.249; 95% CI, 1.221 - 4.143) and surgical procedure (adjusted HR, 2.392; 95% CI, 1.308 - 4.375) were significantly associated with a higher risk of the primary outcome. There were 20 cases of recurrence in RF-TC group, while there were 30 cases in PRF group. The short-term (within 3 months) postoperative recurrence rate was 14.93% in the RF-TC group and 37.31% in the PRF group. The differences in PSQI and NRSs between 2 groups were also statistically significant. LIMITATIONS: The study uses a small sample size from a single center. The model built is not validated internally or externally. The conclusions of randomized controlled trials will be more convincing. Subgroup analysis of the disease course was not performed. CONCLUSION: In the treatment of HZ-related pain, the use of PRF is significantly associated with a high short-term recurrence rate. However, compared with RF-TC, PRF results in milder numbness and less intraoperative pain. RF-TC may be a feasible procedure if patients can accept pain relief at the cost of long periods of numbness, whether RF-TC has the value of clinical promotion still needs to be further explored.

Electroacupuncture (EA) is effective in various chronic pains. NF-κB and CXCL12 modulate the formation of chronic pain. Herein, we hypothesized that EA alleviates cancer-induced bone pain (CIBP) through NF-κB/CXCL12 axis in midbrain periaqueductal gray (PAG), which participates in "top-down" pain modulatory circuits. In order to filter the optimum EA frequency for CIBP treatment, 2, 100, or 2/100 Hz EA was set up. In addition, ipsilateral, contralateral, and bilateral EA groups were established to affirm the optimal EA scheme. Bilateral 2/100 Hz EA was considered as the optimal therapeutic scheme and was applied in a subsequent experiment. Western blotting along with immunofluorescence illustrated that CIBP induces a rapid and substantial increase in CXCL12 protein level and NF-κB phosphorylation in vlPAG from day 6 to day 12. Anti-CXCL12 neutralizing antibody and pAAV-U6-shRNA(CXCL12)-CMV-EGFP-WPRE in vlPAG remarkably improved the mechanical pain threshold of the hind paw in CIBP model relative to the control. EA inhibited the upregulation of pNF-κB and CXCL12 in vlPAG of CIBP. The recombinant CXCL12 and pAAV-CMV-CXCL12-EF1a-EGFP-3Xflag-WPRE reversed the abirritation of EA in the CIBP rat model. NF-κB phosphorylation mediated-CXCL12 expression contributed to CIBP allodynia, whereas EA suppressed NF-κB phosphorylation in CIBP. According to the above evidence, we conclude that bilateral 2/100 Hz EA is an optimal therapeutic scheme for CIBP. The abirritation mechanism of EA might reduce the expression of CXCL12 by inhibiting the activation of NF-κB, which might lead to the restraint of descending facilitation of CIBP.

BACKGROUND: Cold hypersensitivity in the hands and feet is a common clinical symptom in Asian women. Currently, treatment of cold hypersensitivity in the hands and feet is still limited to traditional Chinese medicine, mainly herbal medicine. However, many patients with cold hypersensitivity in the hands and feet in China are not satisfied with the therapeutic effect of herbal medicine, and took medication for a longer time. Chemical lumbar sympathectomy is widely used in the treatment of plantar hyperhidrosis, diabetic foot, recalcitrant erythromelalgia, and other diseases. OBJECTIVES: This study was conducted to evaluate the short-term as well as long-term efficacy, complications, and patient satisfaction of chemical lumbar sympathectomy during treatment cold hypersensitivity in the hands and feet. STUDY DESIGN: A retrospective, observational study. SETTING: Department of Anesthesiology and Pain Medicine, Jiaxing, China. METHODS: A retrospective study of 72 patients with cold hypersensitivity in the hands and feet who received chemical lumbar sympathectomy treatment in our hospital from January 2015 to October 2018 was conducted. The heart rate, non-invasive blood pressure, oxygen saturation, visual analog scale, perfusion index, and plantar temperature were monitored and recorded in before treatment (T1) and after treatment (T2) groups. The patients were followed up on day 1, at week 1, 1 month, 3 months, 6 months, one year, and 2 years after operation for satisfaction, complications, and recurrence. RESULTS: There were no significant differences in heart rate, non-invasive blood pressure, and oxygen saturation between T1 and T2 groups (P > 0.05). Perfusion index and plantar temperature in T2 group were remarkably higher than T1 group, and the difference was statistically significant (P < 0.01). The visual analog scale score of the T2 group was significantly reduced (P < 0.01). Of all the patients who underwent chemical lumbar sympathectomy, the postoperative therapeutic effect was effective in 63 cases (87.5%) and ineffective in 9 cases (12.5%). Among the effective patients, the postoperative curative effect was shown to be excellent in 47 cases and improved in 16 cases. According to the follow-up results at day 1, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after operation, the satisfaction rate was 87.5%, 87.5%, 81.9%, 61.1%, 52.7%, 41.6%, and 34.7%, respectively. There were no serious complications observed and 23 patients relapsed after two years. Multivariate logistic regression analysis results showed that the effect of visual analog scale (OR = 7.312, 95% CI: 1.598 - 33.646, P = 0.011) and plantar temperature (OR = 0.470, 95% CI: 0.288 - 0.766, P = 0.002) on therapeutic effect showed has statistical significance; the effect of gender (OR = 0.654, 95% CI: 0.134 - 3.181, P = 0.599), age (OR = 0.975, 95% CI: 0.916 - 1.039, P = 0.441), perfusion index (OR = 0.710, 95% CI: 0.367 - 1.375, P = 0.310), and disease course (OR = 1.019, 95% CI: 0.997 - 1.042, P = 0.088) on therapeutic effect showed no statistical significance. The effect of gender (OR = 0.451, 95% CI 0.131 - 1.554, P = 0.207), age (OR = 0.961, 95% CI 0.912 - 1.013, P = 0.141), and course of disease (OR = 1.006, 95% CI 0.997 - 1.015, P = 0.203) on postoperative recurrence showed no statistical significance. LIMITATIONS: The nonrandomized, single-center, small sample size, retrospective design is a major limitation of this study. CONCLUSIONS: Chemical lumbar sympathectomy is a valid treatment option for cold hypersensitivity in hands and feet, and computed tomography-guided percutaneous puncture chemical lumbar sympathectomy has the advantages of high success rate, less invasion, less complications, and repeatablity.

BACKGROUND: Radiofrequency thermocoagulation through the supraorbital foramen with a different puncture method is a new approach for the treatment of ophthalmic division trigeminal neuralgia. OBJECTIVES: To compare the efficacy of the vertical puncture method and the transverse puncture method in the treatment of ophthalmic division trigeminal neuralgia during radiofrequency thermocoagulation through the supraorbital foramen. STUDY DESIGN: Randomized, longitudinal prospective, clinical research study. SETTING: Department of Anesthesiology and Pain Medicine, Jiaxing, China. METHODS: A total of 57 patients with ophthalmic division trigeminal neuralgia were enrolled in the study between October 2011 and April 2018, and prospectively randomized into the vertical puncture group (n = 29) or transverse puncture group (n = 28). All these patients received computed tomography guided radiofrequency thermocoagulation through the supraorbital foramen. Patients in the vertical puncture group were treated with a vertical puncture method; patients in the transverse puncture group received a transverse puncture method. Facial pain was evaluated using the Numeric Rating Scale preoperatively and at 1 day, 6 months, 1 year, and 2 years after treatment; facial numbness degree was analyzed at 1 day and 2 years after the treatments were recorded. The short-term and long-term complications during the period of postoperative follow-up were recorded. RESULTS: All surgical procedures were successfully completed. The Numeric Rating Scale scores at 6 months, 1 year, and 2 years after the treatment were significantly lower in the transverse puncture group compared to the vertical puncture group (P < 0.05), while no difference was observed on day one after the treatment (P > 0.05). The numbness degree at 2 years was significantly decreased compared to day one in both groups (P < 0.05). The radiofrequency thermocoagulation for ophthalmic division trigeminal neuralgia in the transverse puncture group showed better long-term outcomes than those in the vertical puncture group (P < 0.05). No short-term or long-term postoperative complications were observed in any of the groups. LIMITATIONS: Additional clinical data should be collected to preserve the results in future work. CONCLUSION: The transverse puncture method during radiofrequency thermocoagulation through the supraorbital foramen had better efficacy and fewer complications in comparison with the vertical puncture method when treating ophthalmic division trigeminal neuralgia.

Bone cancer pain (BCP) is a serious clinical problem that affects the quality of life of cancer patients. However, the current treatment methods for this condition are still unsatisfactory. This study investigated whether intrathecal injection of rosiglitazone modulates the noxious behaviors associated with BCP, and the possible mechanisms related to this effect were explored. We found that rosiglitazone treatment relieved bone cancer-induced mechanical hyperalgesia in a dose-dependent manner, promoted the expression of peroxisome proliferator-activated receptor-γ (PPAR-γ) in spinal cord neurons, and inhibited the activation of the nuclear factor-kappa B (NF-κB)/nod-like receptor protein 3 (NLRP3) inflammatory axis induced by BCP. However, concurrent administration of the PPAR-γ antagonist GW9662 reversed these effects. The results show that rosiglitazone inhibits the NF-κB/NLRP3 inflammation axis by activating PPAR-γ in spinal neurons, thereby alleviating BCP. Therefore, the PPAR-γ/NF-κB/NLRP3 signaling pathway may be a potential target for the treatment of BCP in the future.
RESUMEN
This study aims to explore the value of serum galectin-3 in patients with herpes zoster neuralgia (HZN) and postherpetic neuralgia (PHN) and other factors influencing HZN and PHN occurrence. Samples from forty patients with herpes zoster neuralgia (HZN) (Group H), 40 patients with nonherpes zoster neuralgia (Group N), and 20 cases of health check-up were collected. Patients were divided into PHN group (Group A) and non-PHN group (Group B) according to the occurrence of PHN in Group H. Galectin-3, T-lymphocyte subsets, and IL-6 were recorded in all patients. The changes of galectin-3 in patients with early HZN and PHN were analyzed by single-factor analysis and multifactor analysis. The age (P=0.012) and NRS scores (P < 0.001) of PHN patients were significantly higher than those of non-PHN patients and other neuralgia patients. The ratio of CD3+ (F = 80.336, P < 0.001), CD4+ (F = 12.459, P < 0.001) lymphocyte subsets, and CD4+/CD8+ (F = 15.311, P < 0.001) decreased significantly in PHN patients. The level of blood IL-6 (F = 139.446, P < 0.001) in PHN patients was significantly increased. Serum galectin-3 was significantly higher in HZN patients than in PHN patients (P < 0.05); IL-6 (OR = 10.002, 95% CI: 3.313-30.196, P < 0.001) and galectin-3 (OR = 3.719, 95% CI: 1.261-10.966, P=0.017) were the risk factors for HZN; galectin-3 (OR = 17.646, 95% CI: 2.795-111.428, P=0.002) was also the risk factor for PHN. ROC curve analysis also showed that serum galectin-3 was a better predictor of poor prognosis (AUC = 0.934, P < 0.001). Therefore, as an independent risk factor of HZN and PHN, serum galectin-3 may be used as a new biochemical marker in clinical practice.

Herpes zoster (HZ), commonly called shingles, it is a distinctive syndrome caused by reactivation of varicella zoster virus (VZV). A better understanding of the biological characteristics of HZ patients can help develop new targeted therapies to improve the prognosis. High-throughput proteomics technology can deeply study the molecular changes in the development and progression of HZ disease and integrate different levels of information, this is important to help make clinical decisions. Circulating blood contains a lot of biological information, we conducted a proteomics study of patient plasma, hoping to identify key proteins that could indicate the development of HZ. Compared to healthy human plasma, we found 44 differentially expressed proteins in the plasma of HZ patients, the main pathways involved in these molecules are MAPK signaling pathway, Neuroactive ligand-receptor interaction, Acute myeloid leukemia, Transcriptional misregulation in cancer. We found that 27 proteins have direct protein-protein interactions. Based on the comprehensive score, we identified six key molecules as candidate molecules for further study, and then validated another 80 plasma samples (40 HZ patient plasma and 40 healthy human plasma) using enzyme-linked immunosorbent assay (ELISA), immunoblot assay and receiver operating characteristic (ROC) curve analysis. Finally, we found that the expression levels of these three proteins (PLG, F2, VTN) were significantly lower than those of healthy controls (P < .05). To the best of our knowledge, we first used tandem mass tag (TMT) combined with liquid chromatography-mass spectrometry (LC-MS/MS) to screen for differentially expressed proteins in plasma between HZ patients and healthy individuals. It is preliminarily proved that the plasma protein expression profile of HZ patients is different from that of uninfected patients, it has also been found that these three altered key proteins may be used as biomarkers to test early HZ infection. This study reveals new insights into HZ that help to more accurately identify early HZ patients and to find new therapeutic targets. SIGNIFICANCE: Varicella-zoster virus (VZV; termed human alphaherpesvirus 3 by the International Committee on Taxonomy of Viruses) is a herpesvirus that is ubiquitous in humans and can cause chickenpox and herpes zoster (HZ). After the initial infection of varicella, the VZV goes into a dormant state in the sensory ganglia and cranial nerves. As age or immunosuppression increases, the cellular immunity to VZV decreases, and the virus reactivates and spreads along the sensory nerves to the skin, causing a unique prodromal pain followed by a rash. About one in five people around the world may be infected with VZV at some point in their lives. According to statistics, about one-third of infected people will develop HZ in their lifetime, and an estimated 1 million cases of herpes zoster occur in the United States each year. Herpes zoster can occur at any age and is usually less severe in children and young adults, but the greatest morbidity and mortality are observed in elderly and immunocompromised patients. 20% of patients with HZ have complications including vasculitis, increased risk of myocardial infarction, or postherpetic neuralgia, the overall mortality rate of patients with HZ in the United States is close to 5%. Considering the wide clinical severity and complications of this disease, there is a great need for biomarkers that contribute to early diagnosis, classification of risks, and prediction of outcomes, which will help elucidate the mechanisms underlying their clinical development. As a useful tool in biology, quantitative proteomics can repeatedly identify and accurately quantify proteins in a variety of biological samples. Proteomic analysis focuses on translational proteins, which play a direct role in most biological processes. Although a small number of proteins can be studied simultaneously with traditional methods, such as ELISA and Western blotting, typical proteomics studies can simultaneously analyze thousands of proteins for a more comprehensive identification. Proteomics has been successfully applied to human-based disease research, Analysis of exposed and unexposed subjects based on mass spectrometry (MS) has been found to reveal altered expression of proteins that can be identified as intermediate biomarkers of early disease effects. Tandem mass tags (TMTs) are chemical labels used for MS-based identification and quantification of biological molecules. TMTs play an important role in proteomic analysis in a variety of samples such as cells, tissues, and body fluids. The body fluids that are often detected clinically are blood, which are easy to obtain and contain abundant biological information related to physiological and pathological processes, we hope to develop protein biomarkers from these blood. Therefore, in order to better characterize the pathological process of HZ patients, we performed proteomic analysis of HZ patients and healthy human plasma using the TMT method. This comparison aims to identify specific processes in the development of HZ disease through protein profiling, which may help to improve our biological understanding of HZ.
