Objective To investigate the clinical outcomes of subxiphoid video-assisted thoracoscopic thymectomy for myasthenia gravis. Methods The clinical data of the 85 patients undergoing video-assisted thoracoscopic thymectomy for myasthenia gravis in Department of Cardiothoracic Surgery, Huashan Hospital affiliated to Fudan University between January 2014 and July 2016 were studied. Subxiphoid approach video-assisted thoracoscopic thymectomy (SXVT) and through traditional unilateral approach video-assisted thymectomy (TVAT) were compared. The clinical outcomes of SXVT and TVAT were compared. Results There was no surgical death and no statistical difference between the two groups in drainage time, postoperative volume of drainage, postoperative hospital stay and bleeding volume during operation (P>0.05). However, the acute chest pain after surgery, as well as the postoperative chest pain, and operative time were less in the the SXVT group than that in the TVAT group (P<0.05). Conclusion SXVT for myasthenia gravis is safe and executable. It can alleviate intercostal neuralgia and abnormal chest wall feeling. And it should be considered in the treatment of myasthenia gravis.
By reviewing the current status of chronic pain and combining with the new definition of pain revised by the International Association for the Study of Pain in 2020, firstly a prevention-based approach, self-management of pain, and multidisciplinary collaboration based on the integration of bio-psycho-social-environmental factors is proposed. The medical mode will greatly improve the treatment effect of chronic pain and the quality of life of patients. Secondly, the importance of strengthening humanistic care and paying attention to health education, as well as improving medical staff’s awareness of chronic pain and the level of diagnosis and treatment are pointed out. Finally, it is clarified that innovative non-drug treatments and the establishment of digital pain management platforms are the future of chronic pain.
Pain, as a complex physiological and pathological phenomenon, has always been a hot topic in medical research in terms of its mechanism of occurrence and influencing factors. Vitamin D, as a fat soluble vitamin, has been shown to be closely associated with pain in recent years, in addition to its classic role in regulating calcium and phosphorus metabolism. The polymorphism of the vitamin D receptor (VDR) gene can lead to changes in the structure and function of VDR, thereby affecting vitamin D levels. Meanwhile, VDR gene polymorphism can indirectly or directly participate in the occurrence and development of pain. This article aims to review the research on the relationship between vitamin D and its receptor gene polymorphism and pain, and provide reference for potential therapeutic targets and personalized intervention strategies for pain.
Objective To investigate the effect of lateral retinacular release on the clinical outcomes after total knee arthroplasty (TKA) without resurfacing of the patella. Methods A prospective randomized controlled study was performed on 132 patients with unilateral degenerative knee arthritis undergoing TKA bewteen October 2012 and October 2014, who met the selection criteria. During TKA, lateral retinacular release was used in 66 cases (trial group) and was not used in 66 cases (control group). Two patients were excluded from the study due to missing the follow-up in trial group. Four patients were excluded from the study due to lateral retinacular release in control group. Finally, 64 patients and 62 patients were included in the trial group and in the control group. There was no significant difference in gender, age, body mass index, side, disease duration, preoperative patellar morphology, grading of patellofemoral arthritis, grade of patellar cartilage degeneration, patellar malposition, patellar maltracking, patellar score, and Knee Society Score (KSS) between 2 groups (P>0.05). The operation time, postoperative drainage volume, hospitalization time, postoperative complications, and patient satisfaction were recorded. Postoperative anterior knee pain was assessed by visual analogue scale (VAS), and the knee joint function was evaluated by KSS score and patellar score. The femoral angle, tibial angle, femoral flexion angle, and tibial posterior slope angle were measured on the X-ray film for postoperative prosthetic alignment. The postoperative patellar tracking and patellar position, as well as the presence of osteolysis, prosthesis loosening, patellar fracture and patellar necrosis were observed. Results All patients were followed up for 24 months. There was no significant difference in operation time, postoperative drainage volume, hospitalization time, and patient satisfaction between 2 groups (P>0.05). The incidence of anterior knee pain in the trial group was better than that in the control group (P=0.033). KSS score and patellar score were significantly improved in both groups at 24 months after operation when compared with preoperative scores (P<0.05), but no significant difference was found between 2 groups (P>0.05). Complications included hematoma (2 cases in the trial group, and 1 case in the control group), mild wound dehiscence (2 cases in each group respectively), skin-edge necrosis (1 case in the trial group), and superficial wound infection (1 case in each group respectively), which were cured by conservative treatment. No patellar necrosis, patella fracture, or knee lateral pain occurred in 2 groups. There was no significant difference in complication rate between groups (P=0.392). Satisfactory implant alignment was observed in both groups during follow-up. There was no significant difference in femoral angle, tibial angle, femoral flexion angle, and tibial posterior slope angle between 2 groups (P>0.05). No radiolucent line at the bone-implant interface was seen around the tibial components and femoral components in both groups. The patellar maltracking was observed in 3 patients of the trial group and 5 patients of the control group, showing no significant difference (P=0.488). However, the incidence of patellar malposition in the trial group (18.8%) was significantly lower than that in the control group (35.5%) (χ2=0.173,P=0.034). Conclusion Lateral retinacular release during primary TKA without resurfacing of the patella can reduce postoperative knee pain without increasing complications.
Objective To describe the situation of postoperative pain management in colorectal cancer patient in enhanced recovery after surgery (ERAS) mode, and explore its influenceing factors. Methods From March to December 2017, colorectal cancer patients in ERAS mode in Department of Gastrointestinal Surgery, West China Hospital of Sichuan University were selected. On the third day after surgery, a total of 74 patients with acute pain completed a questionnaire, which was composed of a demographic form, the Houston Pain Outcome Instrument (HPOI), Self-Rating Anxiety Scale, and Social Support Rating Scale. Mean±standard deviation and percentage were used to describe the total score of pain experience, t test, analysis of variance, Spearman correlation analysis were used for single-factor analysis, and multiple linear regression was used for multi-factor analysis. Results The mean total score of pain experience was 15.1±3.8. Single-factor analysis results showed that the affection of pain on daily life (rs=0.270, P=0.020), satisfaction of pain controlling education (rs=–0.283, P=0.015), subjective support (rs=–0.326, P=0.005), and social support utilization (rs=–0.253, P=0.029) were correlated with the total score of pain experience. Multi-factor analysis results showed that satisfaction of pain controlling education (P<0.001) and subjective support (P=0.005) were negative influencing factors of postoperative pain experience score, and severe anxiety (P=0.001) and pain expectation after surgery (P=0.016) were positive influencing factors of postoperative pain experience score. Conclusions Pain management situation is not so bad in these patients. High satisfaction of pain controlling education and high subjective social support are helpful to decrease pain. The medical staff should pay more attention to patients with severe anxiety, and help patients to establish reasonable pain expectation after surgery.
ObjectiveTo evaluate the short-term effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in treatment of buttock pain associated with lumbar disc herniation.MethodsBetween June 2015 and May 2016, 36 patients with buttock pain associated with lumbar disc herniation were treated with PELD. Of 36 cases, 26 were male and 10 were female, aged from 18 to 76 years (mean, 35.6 years). The disease duration ranged from 3 months to 10 years (mean, 14 months). The location of the pain was buttock in 2 cases, buttock and thigh in 6 cases, buttock and the ipsilateral lower extremity in 28 cases. Thirty-four patients had single-level lumbar disc herniation, and the involved segments were L4, 5 in 15 cases and L5, S1 in 19 cases; 2 cases had lumbar disc herniation at both L4, 5 and L5, S1. The preoperative visual analogue scale (VAS) score of buttock pain was 6.1±1.3. VAS score was used to evaluate the degree of buttock pain at 1 month, 3 months, 6 months, and last follow-up postoperatively. The clinical outcome was assessed by the modified MacNab criteria at last follow-up.ResultsAll patients were successfully operated and the operation time was 27-91 minutes (mean, 51 minutes). There was no nerve root injury, dural tear, hematoma formation, or other serious complications. The hospitalization time was 3-8 days (mean, 5.3 days). All incisions healed well and no infection occurred. Patients were followed up 12-24 months (median, 16 months). MRI examination results showed that the dural sac and nerve root compression were sufficiently relieved at 3 months after operation. Patients obtained pain relief after operation. The postoperative VAS scores of buttock pain at 1 month, 3 months, 6 months, and last follow-up were 1.1±0.6, 0.9±0.3, 1.0±0.3, and 0.9±0.4 respectively, showing significant differences when compared with preoperative VAS scores (P<0.05); there was no significant difference in VAS score between the different time points after operation (P>0.05). At last follow-up, according to the modifed MacNab criteria, the results were excellent in 27 cases, good in 9 cases, and fair in 2 cases, and the excellent and good rate was 94.4%.ConclusionPELD can achieve satisfactory short-term results in the treatment of buttock pain associated with lumbar disc herniation and it is a safe and effective minimally invasive surgical technique.
ObjectiveTo systematically review the prevalence and risk factors of the chronic post-cesarean section pain (CPCSP). MethodsPubMed, EMbase, The Cochrane Library, CINAHL, PsycInfo, CBM, WanFang Data, VIP, and CNKI databases were electronically searched to collect studies on the prevalence and risk factors of CPCSP from inception to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 15.1 software. ResultsA total of 43 studies involving 12 435 participants were included. The results of meta-analysis showed that the prevalence of CPCSP for 2 to 5 months, 6 to 11 months, and at least 12 months were 19% (95%CI 15% to 23%), 13% (95%CI 9% to 17%), and 8% (95%CI 6% to 10%), respectively. The risk factors included preoperative pain present elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety, postpartum depression, etc. ConclusionsThe current evidence shows that the overall prevalence of CPCSP is high. Preoperative pain presents elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety and postpartum depression may increase the risk of CPCSP.
Objective To discuss the prophylactic effect of handling inguinal nerves correctly duing Lichtenstein inguinal hernia repair on chronic pain after operation. Methods 158 patients with inguinal hernia who were treated in our hospital from February 2007 to March 2010 were given Lichtenstein hernia repair. The ilioinguinal nerves were carefully identified and preserved during the operation, the nerve excision had been carried on only in the cases of existing nerve injuried or interference with the position of the mesh. Results The identification rate of iliohypogastric nerve, ilioinguinal nerve, and genital branch of genitofemoral nerve was 87.97%（139/158）, 82.28%（130/158）, and 34.18%（54/158）, respectively. The postoperative complication rate was 5.06%（8/158）, in which subcutaneous hydrops 5 cases, scrotal hematoma 2 cases, and wound infection 1 case, all recovered by conservative management. There was not inguinal hernia recurrence in 12 months of follow-up. In 1 month after operation, there were 63（39.87%） patients suffered from mild pain and 34（21.52%） patients suffered from moderate pain in inguinal region, there was no patient with severe pain, the mean pain score was 0.83. The incidence of chronic groin pain in 6 months was 5.06% （8/158）, in which 7（4.43%） patients suffered from mild pain, and 1（1/158） patient suffered from moderate pain. In 12 months, only 4（2.53%） patients still experience occasional pain or discomfort, the mean pain score was 0.03. Multinomial logistic regression analysis indicated that neurectomy had no influence on postoperative pain（P＞0.05）and non-identification of ilioinguinal nerve was a risk factor for early（1 month） postoperative moderate pain（OR=3.373, P=0.030）. Conclusions Standard surgical procedure acted according to the Lichtenstein guidelines and handling inguinal nerves correctly can result in low incidence of chronic pain after operation, and can make the patients have a better quality of life.
The American Heart Association and other six major associations jointly released AHA/ACC/ASE/CHEST/SAEM/SCCT/SCMR Guideline for the Evaluation and Diagnosis of Chest Pain for the first report on October 28th, 2021. This guideline stresses the risk stratification and the diagnostic workup of acute chest pain, considers the cost-effectiveness of low-risk chest pain diagnosis and examination, and recommends sharing decisions with patients. This guideline mainly involves the initial evaluation of chest pain, choosing the right pathway with patient-centric algorithms for acute chest pain, and the evaluation of patients with stable chest pain. This review makes a detailed interpretation of the recommended points of the guideline through reviewing the literature.
Objective To conduct a systematic review of the construction methods, predictive factors, and model quality of risk prediction models for postoperative chronic pain in knee replacement surgery patients, providing evidence for the development of nursing-sensitive dynamic prediction models. Methods A systematic review of risk prediction models for postoperative chronic pain in knee replacement surgery patients was conducted by searching PubMed, Web of Science, Cochrane Library, CINAHL, SinoMed, CNKI, Wanfang Database, and VIP Database. The search period was from the establishment of the databases to February 28, 2025. Two researchers independently screened the literature, extracted data, and assessed the risk of bias and applicability of the included studies. Results A total of 10 studies involving 10 predictive models were included in this review. Among these, three models underwent internal validation, and one model underwent external validation. Commonly reported predictive factors included postoperative 24-hour Numerical Rating Scale scores, postoperative knee function scores, sleep disorders, preoperative depression, postoperative functional exercises, postoperative complications, preoperative pain, and postoperative C-reactive protein levels. All 10 studies had a high risk of bias and were generally applicable. Conclusions Existing risk prediction models generally rely on static indicators and lack dynamic monitoring of postoperative rehabilitation behaviors and psychosocial factors, with severe deficiencies in model validation. Future research should focus on developing nursing-led multidimensional dynamic models that incorporate functional exercise adherence data collected via wearable devices, standardize external model validation, and enhance clinical translation value.
