Objective To evaluate the clinical effects of surgical treatment for 30 patients with discogenic low back pain. Methods A total of 30 patients with 36 intervertebral discs were treated with posterior approach lumbar discectomy and interbody fusion with internal fixation by strict criteria. All patients were followed up for one year. The low back pain before and one year after surgery was evaluated by Japanese Orthopaedic Association (JOA) score and Visual Analogue Scale (VAS) score. Results The patients’ JOA score increased from 14.6±2.3 (before operation) to 27.1±0.9 (one year after operation) (t=–26.936, P<0.001), while the patients’ VAS score decreased from 6.2±1.6 (before operation) to 1.4±0.9 (one year after operation) (t=16.335, P<0.001), and the differences were significant. Conclusion When the conservative treatment is invalid, the operation of posterior lumbar intervertebral fusion is an effective method for the patinets with discogenic low back pain.
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.
Objective To investigate whether the peri pheral administration of amitri ptyl ine produces antihyperalgesiceffect following the chronic constriction injury (CCI) of the sciatic nerve in rats. Methods Forty-eight maleCCI rats weighing (220 ± 20) g were randomly divided into 6 groups (n=8)：group NS, group A2.5, group A5, group A10,group A15.9 and group Aip. In the group NS, group A2.5, group A5, group A10 and group A15.9, sciatic nerve blockade was locally performed with 0.5 mL normal sal ine, and 2.5, 5.0, 10.0, 15.9 mmol/L amitriptyl ine respectively through implanted cannulas on the 7th day after operation. In the group Aip, amitriptyl ine (2.5 mg) was administered by intraperitoneal injection. The mechanical withdrawal threshold (MWT), thermal withdrawal latency (TWL) and motor function were measured before and 1, 2, 4, 8, 12, 24 and 48 hours after sciatic nerve blockade. Results Forty-eight CCI rats were all survival without infection palsy and catheter fall ing off. The rats of group A2.5, group NS and group Aip didn’t produce ambulation deficits. There were no significant difference in these 3 groups (P gt; 0.05). However compared with group A2.5, group NS and group Aip, the rats of group A5, group A10, group A15.9 all produced significant ambulation deficits (P lt; 0.05). The ambulation deficits lasted 2 hours (group A5), 4 hours (group A10), 8 hours (group A15.9) respectively. But the ambulation deficits of CCI rats were all reversible. The MWT and TWL of groups with local injection of amitriptyl ine increased when conpared with group NS, group Aip and those of before injection (P lt; 0.05). Sciatic nerve blockade with amitriptyl ine significantly suppressed mechanical hyperalgesia and thermal hyperalgesia in neuropathic rats. The peripheral anti-hyperalgesic effects lasted 2 hours (A2.5 group), 4 hours (group A5), 24 hours (group A10), 24 hours (group A15.9) respectively. But there were no significant difference between A10 group and A15.9 group (P gt; 0.05). There were no significant difference between group NS and group Aip (P gt; 0.05). Conclusion The peri pheral anti-hyperalgesic effects can be found in sciatic nerve blockade of amitri ptyl ine on CCI rats. And this effect of amitri ptyl ine has concentration dependent and ceil ing effect. Amitri ptyl ine of 5.0-15.9 mmol/L can produce significantambulation deficits which are reversible.
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.
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.
ObjectiveTo evaluate the degree of psychological pain for cancer patients undergoing surgical treatment and analyze the contributory factors to provide the theoretical basis for psychological intervention for cancer patients with surgical treatment.MethodsThe clinical data of 455 cancer patients who received surgeries in our hospital from November 2020 to January 2021 were retrospectively analyzed, including 225 males and 230 females aged 53.80±13.50 years. By applying the method of convenient sampling, a cross-sectional survey was carried out by gathering the general information of the patients and evaluating their mental condition with the distress thermometer. The contributory factors were discussed by logistic regression analysis.ResultsThe score for the psychological pain of the patients was 4.11±2.49 points. The main factors contributing to the psychological pain were physical problems, emotional problems and family matters. The logistic regression analysis showed that the main factors related to the degree of psychological pain were cancer types (P=0.023), religious belief (P=0.046), number of niduses (P=0.016), respiratory status (P=0.004), medical expense (P=0.007), grief (P=0.001) and anxiety (P=0.040).ConclusionNearly half of the patients have been subjected to apparent psychological pain, and emotion and physical problems are the main factors. It is crucial to pay attention to the patients’ mental problems, seek convenient tools for psychological evaluation, and take actions to deal with the psychological problems and physical symptoms.
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 investigate the effect of preoperative gum chewing on the postoperative rehabilitation of patients undergoing gynecologic laparoscopic surgery.MethodsA total of 160 patients undergoing elective gynecologic laparoscopic surgery between January and May 2013 were selected to participate in the study. Each patient was randomly assigned to one of the two groups: the trial group (n=80) or the control group (n=80). Thirty to sixty minutes before the surgery, the patients in the trial group chewed one piece of sugarless gum for at least 30 minutes, and then removed the gum before being taken to the operating room; while the patients in the control group chewed nothing. The time to first passage of flatus and the time to first defecation after surgery, length of hospital stay, the degrees of pain at 2-, 4-, 6-, 8-, 24-, 48-hour after surgery, the incidences of postoperative nausea, vomiting, and abdominal distension, postoperative analgesic and antiemetic drug requirement were recorded.ResultsThe mean time to first passage of flatus was significantly earlier in the trial group than that in the control group [(16.49±7.64) vs. (20.25±7.94) hours, P=0.003]. The mean time to first defecation was significantly earlier in the trial group than that in the control group [(48.16±15.25) vs. (55.80±18.97) hours, P=0.006]. The degree of pain at 2-hour after surgery was significantly lighter in the trial group than that in the control group (P<0.05). Fewer participants in the trial group than in the control group experienced postoperative nausea (43.75% vs. 61.25%, P=0.027). There were no significant differences in the length of hospital stay, the degrees of pain at 4-, 6-, 8-, 24- and 48-hour after surgery, incidences of postoperative vomiting and abdominal distension, postoperative analgesic, or antiemetic drug requirement between the two groups (P>0.05).ConclusionsGum chewing before surgery can promote the recovery of gastrointestinal function, reduce postoperative short-term pain, and promote postoperative rehabilitation in patients undergoing gynecologic laparoscopic surgery. Gum chewing before surgery can be used clinically as an easy, inexpensive, safe, and effective procedure.
Objective To observe the effects of extracorporeal shock wave therapy (ESWT) combined with kinesio taping (KT) on chronic non-specific low back pain (CNLBP). Methods CNLBP patients who visited the Department of Rehabilitation Medicine, the Second Affiliated Hospital of Nantong University between January 2021 and January 2022 were selected. The included patients were divided into ESWT group, KT group, and combined treatment group using a random number table method. All patients received conventional rehabilitation. The ESWT group was treated with ESWT, the KT group was given KT therapy, and the combined treatment group were treated with ESWT and KT with the same treatment frequency as before. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), MOS 36-item Short form Health Survey (SF-36) and Self-rating Anxiety Scale (SAS) were used to evaluate pain severity, lumbar spine function, quality of life, and anxiety status in all groups before and 4 weeks after treatment, respectively. Results A total of 85 patients were included. Among them, there were 29 cases in the ESWT group, 28 cases in the KT group, and 28 cases in the combined treatment group. There was no adverse event in any group. The intra-group comparison results showed that the VAS, ODI, and SAS scores of the three groups after 4 weeks of treatment were lower than those before treatment (P<0.05), while the SF-36 scores in all dimensions were higher than those before treatment (P<0.05). Before treatment, there was no statistically significant difference in VAS, ODI, SAS, or SF-36 scores among the three groups (P>0.05). After 4 weeks of treatment, there were statistically significant differences in VAS, ODI, SAS, and SF-36 scores among the three groups (P<0.05). The results of multiple comparisons between groups showed that the VAS scores of the ESWT group and the combination therapy group were lower than those of the KT group (P<0.05); the ODI scores of the combination therapy group were lower than those of the ESWT group and the KT group (P<0.05); the SAS scores of the combination therapy group were lower than those of the KT group (P<0.05); the SF-36 scores of each dimension were compared in pairs among the three groups, and the differences were statistically significant (P<0.05); there was no statistically significant difference in pairwise comparison of other indicators between groups (P>0.05). Conclusion ESWT combined with KT can more effectively improve the pain and lumbar spine function of patients with CNLBP, and improve the quality of life of patients.
Acute pancreatitis (AP) is an acute abdominal disease characterised by inflammation of the pancreas. Acute severe upper abdominal pain is the leading symptom and primary reason for emergence hospital admission of AP patients. Nowadays, more and more research has focused on the cross-talk between the exocrine pancreas and pancreatic projecting neurons (neurogenic inflammation) for pain in AP. Elucidating the molecular mechanisms of neurogenic inflammation for pain in AP will provide insights into targeted analgesics development in this setting.
