RESUMEN
BACKGROUND: The classic percutaneous balloon compression (PBC) technique is used to complete an operation under the guidance of C-arm radiography under general anesthesia, making communication with patients during the operation impossible. It is not accurate or objective to predict the classic technique's curative effect solely by determining whether the projection of the x-ray lateral image of the filled balloon is pear-shaped. OBJECTIVES: This study aimed to upgrade classic PBC to awake computed tomography (CT)-guided PBC technology under conscious local anesthesia and analgesia monitoring. STUDY DESIGN: Prospective clinical study. SETTING: Department of Anesthesiology and Pain Medical Center, Jiaxing, People's Republic of China. METHODS: Puncture was designed and guided by CT scanning, and the curative effect was assessed by asking the patients about what they are feeling during the operation. RESULTS: CT can design the puncture path and accurately guide puncture, observe the position and shape of the balloon through 3-dimensional reconstruction during the operation, and judge the curative effect according to the patient's chief concern. LIMITATIONS: Local anesthetic analgesia is not perfect, resulting in some patients experiencing pain during surgery. CONCLUSIONS: PBC can be completed under conscious local anesthesia and analgesia. Its curative effect and operative end standard can be determined according to the patient's chief concern. Under CT guidance, the puncture path can be designed to complete an accurate puncture and to intuitively understand the position and shape of the balloon.

BACKGROUND: The factors influencing pain recurrence following V1 trigeminal nerve surgery are still unknown. OBJECTIVE: We aimed to analyze the risk factors affecting pain recurrence following surgery in the V1 branch of the trigeminal nerve, construct a nomogram-based therapeutic efficacy prediction model using logistic regression analysis, and validate the model's predictive performance. STUDY DESIGN: A retrospective study. SETTING: This study was performed at the Affiliated Hospital of Jiaxing University, People's Republic of China. METHODS: Data were retrospectively collected from 131 patients with trigeminal neuralgia and V1 branch algesia who underwent either radiofrequency thermocoagulation through the supraorbital foramen or percutaneous balloon compression at the Pain Department of the Affiliated Hospital of Jiaxing University from March 2017 through January 2021. The patients were randomly divided into a training group (n = 92) and a testing group (n = 39) in a 7:3 ratio. A least absolute shrinkage and selection operator (LASSO) regression was used to screen independent predictive factors. The outcome variable was whether the patient experienced pain recurrence within 2 years postsurgery. Those results were used to construct a nomogram-based predictive model, followed by a multivariate logistic regression analysis. The feasibility of the nomogram-based predictive model was evaluated by the validation group. Finally, the predictive model's discrimination ability, accuracy, and clinical usability were evaluated using a receiver operating characteristic curve, calibration curves, and decision curve analysis, respectively. RESULTS: The results indicate that among the total 131 patients, 76 patients did not experience pain recurrence within 2 years postsurgery, while 55 patients suffered a pain recurrence. The results of the LASSO regression, combined with a multivariate logistic regression analysis, showed that age, pre-Numeric Rating Scale score, and surgery type were the influencing factors for patients with V1 branch pain who experienced pain recurrence within 2 years postsurgery (P < 0.05). From this data a nomogram-based predictive model was established. The area under the curve of the nomogram-based predictive model for the training group was found to be 0.890 (95% CI, 0.818 - 0.961); in the test group it was 0.857 (95% CI, 0.748 - 0.965) in the test group. The Hosmer-Lemeshow goodness-of-fit test revealed an excellent fit (P > 0.05), while the decision curve analysis showed that the net benefit of using the nomogram-based predictive model to predict the risk of recurrence after 2 years was higher when the patient's threshold probability was 0 to 0.990. LIMITATIONS: This was a single-center study. CONCLUSION: A high-precision nomogram-based predictive model was successfully established and validated (with predictive variables including age, pre-Numeric Rating Scale score, and surgery type). We envisage this model will help improve the early identification and screening of high-risk patients for postsurgery pain recurrence of the V1 trigeminal nerve branch.

Zoster-associated pain (ZAP) is a painful condition that significantly impacts a patient's quality of life, often leading to postherpetic neuralgia (PHN). Over 30% of patients with herpes probably experience PHN. However, the understanding and treatment of ZAP remain inadequate. Common interventional treatments include radiofrequency therapy, nerve blocks, epidural block, and spinal cord electrical stimulation. Among these, radiofrequency therapy is widely used for pain control in ZAP, but the standard pulsed radiofrequency technique can still be improved. Researchers have explored different radiofrequency parameters, modes, targets, and combined treatments to enhance the therapeutic effect. In this paper, we review the latest research findings and incorporate our own departmental investigations. We conclude that high-voltage, long-duration pulsed radiofrequency and radiofrequency thermocoagulation therapy have shown improved therapeutic outcomes, despite some remaining limitations. Emphasis is placed on safety in intercostal nerve and extracranial nerve radiofrequency treatments. Combination therapy is also safe and effective; however, many studies have a low grade of evidence. Further high-quality research and systematic reviews are needed.
RESUMEN
INTRODUCTION: This study aimed to analyze the risk factors affecting the recurrence of cervical spondylotic radiculopathy after surgery, construct a nomogram predictive model, and validate the model's predictive performance using a calibration plot. METHODS: In this study, 304 cervical spondylotic radiculopathy patients who underwent computed tomography (CT)-guided radiofrequency ablation (RFA) of cervical intervertebral discs or low-temperature plasma RFA for cervical radiculopathy were enrolled at the Pain Department of Jiaxing College Affiliated Hospital from January 2019 to March 2022. The patients were randomly divided into training (n = 213) and testing (n = 91) groups in a 7:3 ratio. Lasso regression analysis was used to screen for independent predictors of recurrence 1 year after surgery. A nomogram predictive model was established based on the selected factors using multiple logistic regression analysis. RESULTS: One year after surgery, 250 of the 304 cervical spondylotic radiculopathy patients did not have recurrences, while 54 had recurrences. Lasso regression combined with multiple logistic regression analysis revealed that duration, numbness, and the Numeric Rating Scale (NRS) were significant predictors of recurrence 1 year after surgery (P < 0.05). A nomogram predictive model was established using these variables. The area under the curve (AUC) of the nomogram predictive model for predicting recurrence in the training group was 0.918 [95% confidence interval (CI) 0.866-0.970], and the AUC in the testing group was 0.892 (95% CI 0.806-0.978). The Hosmer-Lemeshow goodness-of-fit test exhibited a good model fit (P > 0.05). Decision curve analysis (DCA) indicated that the nomogram predictive model had a higher net benefit for predicting the risk of postoperative recurrence in cervical radiculopathy patients when the threshold probability was between 0 and 0.603. CONCLUSION: This study successfully developed and validated a high-precision nomogram prediction model (predictive variables include duration, numbness, and NRS) for predicting the risk of postoperative recurrence in cervical radiculopathy patients. The model can help improve the early identification of high-risk patients and screening for postoperative recurrence.
RESUMEN
BACKGROUND: Factors influencing recurrence after V3 trigeminal nerve surgery remain unknown. OBJECTIVES: To analyze the risk factors affecting recurrence after trigeminal nerve branch V3 surgery, construct a nomogram prediction model, and verify the predictive efficacy of the model. STUDY DESIGN: A retrospective study. SETTING: This study was performed at the Affiliated Hospital of Jiaxing University, China. METHODS: Patients with mandibular nerve pain of the V3 branch of the trigeminal nerve treated with percutaneous puncture foramen ovale trigeminal mandibular nerve radiofrequency or trigeminal semilunar nerve microballoon compression at the Pain Department of the Affiliated Hospital of Jiaxing College, between January 2016 and April 2021, were enrolled and randomly divided into the training group (n = 108) and the test group (n = 47) according to the ratio of 7:3. The feasibility of the nomogram prediction model was further explored using multifactor logistic regression analysis based on the screening of independent predictors by the least absolute shrinkage and selection operator (LASSO) regression analysis using recurrence in one year after surgery as the outcome variable, and was assessed by the validation group. Finally, the discriminatory power, accuracy, and clinical utility of the prediction model were assessed using the area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA), respectively. RESULTS: Among the 155 patients with trigeminal V3 pain, 128 had no recurrence and 27 had recurrence one year after surgery. LASSO regression combined with multifactorial logistic regression analysis showed that age, procedure, and duration were factors influencing recurrence one year after surgery (P < 0.05). A nomogram prediction model was developed using the above variables. The AUC of the nomogram prediction model was 0.749 (95% CI [0.618, 0.879]) in the training group and 0.793 (95% CI [0.584, 0.980]) in the test group for postoperative recurrence of V3. The DCA showed that the net benefit of using the nomogram prediction model to predict the risk of postoperative recurrence of the V3 branch of the trigeminal nerve was higher when patients had a threshold probability of 0 to 0.486. LIMITATIONS: This was a single-center study. CONCLUSIONS: This study successfully developed and validated a highly accurate nomogram prediction model (with age, procedure, and duration as predictive variables), which can improve the early identification and screening of patients at high risk of recurrence after trigeminal nerve V3 branch surgery. KEY WORDS: Trigeminal neuralgia, mandibular nerve, risk factors, prediction model.

BACKGROUND: The factors influencing relapse after radiofrequency operation of the V2 branch of the trigeminal neuralgia are yet to be identified. OBJECTIVES: The risk factors affecting recurrence after radiofrequency operation of the V2 branch of the trigeminal neuralgia were analyzed, and a curative effect prediction model was constructed. STUDY DESIGN: A retrospective study. SETTING: This study was conducted at the Affiliated Hospital of Jiaxing University, People's Republic of China. METHODS: The records of patients with maxillary nerve pain in the V2 branch of the trigeminal nerve who underwent computed tomography-guided foramen rotundum radiofrequency treatment at the Pain Department of the Affiliated Hospital of Jiaxing College from April 2014 through December 2020 were collected and randomly divided into training (n = 137) and test (n = 59) groups at a 7:3 ratio. The outcome variable was whether or not recurrence was observed 2 years postsurgery. Independent predictors were screened by LASSO (least absolute shrinkage and selection operator) regression analysis. Based on these findings, a nomogram prediction model was explored further and developed using multifactor logistic regression analysis. Also, the feasibility of the nomogram prediction model for recurrence after radiofrequency was assessed using a validation group. Finally, the discriminatory power, accuracy, and clinical utility of the prediction model were evaluated using the receiver operating characteristic (ROC), area under the curve (AUC), calibration curve, and decision curve analysis (DCA), respectively. RESULTS: LASSO regression, combined with multifactorial logistic regression analysis, identified factors such as age, duration, branches, and numbness that influence V2 trigeminal nerve pain recurrence in patients 2 years post-radiofrequency surgery (P < 0.05). The above variables were used to construct the nomogram prediction models. The AUC of the nomogram prediction model predicted that the recurrence post V2 radiofrequency was 0.726 in the training group and 0.611 in the test group. The DCA showed that the columnar plot prediction model predicted the risk of recurrence post-radiofrequency of the V2 branch of the trigeminal nerve had a threshold probability of 0 - 0.9. LIMITATIONS: This was a single-center study. CONCLUSION: A highly accurate nomogram prediction model (predictor variables include age, duration, branches, and numbness) was developed to improve the early identification and screening of patients at high risk of recurrence after V2 trigeminal nerve radiofrequency surgery. KEY WORDS: Trigeminal neuralgia, maxillary neuralgia, radiofrequency, risk factors, prediction model.

Objective: To investigate the effectiveness and safety of computed tomography (CT)-guided radiofrequency thermocoagulation (RFTC) of the thoracic sympathetic nerve versus chemical resection (CTS) for the treatment of pain caused by Raynaud's disease. Methods: Patients who underwent CTS or thoracic sympathetic nerve RFTC between March 2012 and March 2021 were enrolled in this retrospective study. There were 28 cases in the alcohol group (Group A) and 44 in the radiofrequency group (Group R). Visual analog scores (VAS) were collected from patients at different time points, as well as preoperative and postoperative finger end perfusion index (PI) and hand temperature (T). The efficiency, postoperative recurrence rate, complications, and improvement in postoperative quality of life were observed in both groups. Results: Pain scores at different follow-up times after surgery decreased in both groups compared to the preoperative period (P < 0.05). Postoperative T and PI were higher in both groups than preoperatively all (P < 0.05). The recurrence rate was higher in the R group than in the A group. Postoperative complications were observed in 13.6% and 25% of patients in groups R and A, respectively. Meanwhile, the postoperative quality of life improved in both groups, but the radiofrequency (RF) group was better than the alcohol group in terms of improvement in quality of life (P < 0.05). Conclusion: Both CT-guided CTS and RFTC of the thoracic sympathetic nerve provided good treatment outcomes. However, the RF group was superior to the alcohol group in terms of complication rate and quality of life improvement.
RESUMEN
PURPOSE: Papillary thyroid carcinoma (PTC) is the most common thyroid cancer. Non-alcoholic Fatty Liver Disease (NAFLD) was possibly among the risk factors for thyroid carcinoma. It is uncertain whether NAFLD is associated with the aggressiveness of PTC. METHODS: We obtained data on patients with PTC who had undergone surgery at the First Affiliated Hospital of Wenzhou Medical University between January 2020 and February 2022. Pre-and post-operative data were obtained from electronic medical records and analyzed. Patients were split into two groups based on the NAFLD diagnostic criteria and compared using univariate and multivariate analysis through a logistic regression model. RESULTS: In all, 3468 patients with PTC were included in this study, of which 594 (17.1%) were diagnosed with NAFLD. NAFLD was found to be an independent risk factor for lymph node metastasis (OR = 1.285 95% CI: 1.052-1.570), incidence of BRAF V600E mutation (OR = 1.504, 95% CI: 1.148-1.972) and later tumor stage at diagnosis (OR = 2.310, 95% CI: 1.700-3.139) in PTC. The association mentioned above remained significant in subgroups of patients with Hashimoto's thyroiditis (HT), hypertension, diabetes (DM), high triglyceride (TG) levels, low levels of high-density lipoprotein-cholesterol (HDL-C), and high body mass index (BMI). In subgroup of female rather than male, NAFLD was an independent risk factor for lymph node metastasis (OR = 1.638 95% CI: 1.264-2.123), incidence of BRAF V600E mutation (OR = 1.973, 95% CI: 1.368-2.846) as well as later tumor stage (OR = 2.825, 95% CI: 1.964-4.063) in PTC. However, NAFLD was not a risk factor for the larger tumor size (>1 cm), extra-thyroidal extension (ETE), or multifocality in PTC. CONCLUSION: Our cross-sectional study indicated that there is a strong association of NAFLD with higher incidence of lymph node metastasis, higher incidence of BRAF V600E mutation and later TNM stage than non-NAFLD in females with PTC.

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.

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.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness and safety of computed tomography (CT)-guided radiofrequency thermocoagulation (RFTA) of the sphenopalatine ganglion (SPG) for patients with refractory headache. METHODS: A total of 14 patients with refractory migraine and 10 patients with cluster headache (CH) who underwent CT-guided SPG RF between May 2019 and August 2021 at the Jiaxing First Hospital, located in Jiaxing City, Zhejiang Province, China, were included and analyzed in this retrospective cohort study. Pain score, sleep quality scores, and treatment effects were observed before operation as well as 1 day and 1, 3, 6, 12, and 24 months after surgery. Also, the incidence of facial numbness at different timepoints after operation was evaluated. RESULTS: The frequency and duration of attacks decreased after treatment in patients with migraine, and the shortening of the cluster period and the prolongation of the remission period after treatment in patients with CH indicated that the treatment was effective. The numeric rating scale (NRS) ranged from 0 to 10, where 0 meant no pain and 10 meant the worst imaginable pain. The NRS of patients at 1 day and 1, 3, 6, 12, and 24 months after surgery was significantly lower than before operation (P < 0.05). The treatment of patients with migraine and CH was effective. The overall incidence of numbness in patients with migraine and the total incidence of numbness in patients with CH was recorded. The total incidence of numbness decreased gradually, but no significant difference was detected in the incidence of numbness between the two groups (P > 0.05). No serious adverse reactions, such as orthostatic hypertension, intracranial infection, and visual disturbance, occurred in the patients after operation. CONCLUSION: CT-guided RFTA of the SPG significantly relieves headache symptoms in patients with refractory migraine and CH. It has the advantages of rapid onset, long duration, and a safe and reliable treatment process, making it worthy of clinical application.
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: 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: Resistant hypertension (RH) has always been a difficult problem in clinical diagnosis and treatment. At present, there is no recognized safe and effective minimally invasive treatment. CASE SUMMARY: An 80-year-old woman was admitted to hospital due to trigeminal neuralgia (TN). The patient had a history of RH for more than 10 years and her blood pressure (BP) was not well-controlled. Before the treatment for TN, we decided to perform chemical renal sympathetic denervation with ethanol in the Pain Department of our hospital. One year after the operation, she stopped taking antihypertensive drugs, and her BP was satisfactorily controlled within 4 years after surgery. CONCLUSION: Computed tomography-guided chemical renal sympathetic modulation may be a feasible method for the treatment of RH.

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.

BACKGROUND: Computed tomography (CT)-guided radiofrequency thermocoagulation of lumbar sympathetic nerve has been gradually applied to the treatment of many autonomic nerve disorders, such as plantar hyperhidrosis (PH) and diabetic peripheral neuropathy (DPN). The difference in the success rate of operation between the left and right sides is not yet studied. OBJECTIVE: This study aimed to explore a statistically significant difference between the success rate of left and right CT-guided radiofrequency thermocoagulation of lumbar sympathetic nerve and screen the risk factors affecting the success rate of the right surgery. STUDY DESIGN: This is a single-center retrospective cohort 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 86 patients who received CT-guided radiofrequency thermocoagulation of lumbar sympathetic nerve were included in this study approved by the Ethics Committee of the affiliated Hospital of Jiaxing University. Nonparametric and chi-square tests were used to compare the operation times, CT scan times, and success rate on the left and right sides. Binary multivariate logistic regression analysis was applied to screen the risk factors on the outcome variable. RESULTS: The bilateral operation time, CT scan times, and success rate differed significantly between the left and right sides (P < 0.05). After univariate analysis, 6 covariates (gender, body mass index, treatment history, operation time, CT scan times, and puncture needle type) were selected. Finally, the multivariate regression model screened out 2 risk factors: the operation time and puncture needle type. LIMITATIONS: We look forward to increasing the sample size in follow-up studies and exploring relevant conclusions in randomized controlled trials. CONCLUSION: This study proved that in CT-guided radiofrequency thermocoagulation of the lumbar sympathetic nerve, the difficulty of operation on the right side was significantly high, and the success rate was also lower than that on the contralateral side. Multivariate logistic regression analysis showed that operation time and type of puncture needle were risk factors affecting the success rate of the operation. These findings laid a foundation for the accomplishment of technical improvement and innovation in the future. A preliminary exploration was carried out to reduce the risk and complications and to improve the success rate of the operation.

OBJECTIVES: To describe the method and clinical efficacy of awake computed tomography (CT)-guided percutaneous balloon compression (PBC) as a treatment for trigeminal neuralgia (TN). DESIGN: In this case series, patients with TN were treated with awake CT-guided PBC and followed up for treatment efficacy and complications for 12 months. SETTING: A single-center study. SUBJECTS: A total of 66 patients with medical treatment-refractory TN were recruited for the study. METHODS: The procedure was performed under moderate sedation. A balloon catheter was inserted through a trocar needle to reach Meckel's cavity under CT guidance. The position and optimal shape of the contrast-filled balloon were confirmed with CT three-dimensional reconstruction. Compression of the trigeminal ganglion was considered complete when the patient notified operators about facial hypoesthesia or the resolution of TN symptoms. All patients were followed up monthly for 12 months to monitor treatment efficacy and complications. RESULTS: The average trigeminal ganglion compression time was 272 ± 81 seconds, at which point the patients reported significant facial hypoesthesia compared with the contralateral side or resolution of triggered pain in the affected area. All patients had resolution of TN symptoms for 6 months, with a 1-year recurrence rate of 13%. The overall safety profile was improved with the technique described in this study. Side effects, such as hypoesthesia and mastication weakness, were overall mild and did not impact patients' quality of life. Some complications that historically have been associated with PBC, such as diplopia and keratitis, were not present. CONCLUSIONS: This new awake CT-guided PBC technique produces better outcomes than the traditional PBC under fluoroscopy guidance and general anesthesia.

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.
