Study on the effect of percutaneous intervertebral foraminoscopic discectomy in the treatment of lumbar disc herniation.

ABSTRACT: This study explored the effect of percutaneous intervertebral foraminoscopic discectomy (PIFD) in the treatment of lumbar disc herniation (LDH).This retrospective study collected a total of 88 patient cases for inclusion. Epidemiological and clinical data of patients with LDH at the First Affiliated Hospital of Jiamusi University between May 2017 and January 2020 were retrospectively analyzed. Of those, 44 patients received PIFD and were allocated to an intervention group. The other 44 patients administrated fenestration discectomy (FD), and were assigned to a control group. We compared surgery time (minute), incision length (cm), duration of hospital stay after surgery (day), pain intensity (as checked by Visual Analogue Scale (VAS), health-related quality of life (as examined by Oswestry Disability Index, ODI), and complications between 2 groups.There were not significant differences in surgery time (minute) (P = .56), VAS (P = .33) and ODI (P = .46) after surgery between 2 groups. However, there were significant differences in incision size (cm) (P < .01) and length of hospital stay (day) (P < .01) after surgery between 2 groups. When compared before the surgery, patients in both groups had significant improvements in VAS (P < .01) and ODI (P < .01) after the surgery. Moreover, both groups had similar safety profiles (P > .05).The findings of this study showed that both PIFD and FD benefit patients with LDH. However, PIFD can benefit patients more than FD in the incision size and duration of hospital stay after surgery.

Efficacy of extracorporeal shock wave combined spinal core decompression for the treatment of patients with femoral head necrosis: A protocol for systematic review and meta-analysis.

BACKGROUND: Previous studies have reported that extracorporeal shock wave (EPSW) combined spinal core decompression (SCD) has been used for the treatment of patients with femoral head necrosis (FHN) effectively. However, their results are still inconsistent. Therefore, this study will systematically assess the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. METHODS: This study will systematically search the following databases from inception through March 1, 2020: MEDLINE, Web of Science, Scopus, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and China National Knowledge Infrastructure. All searches will be performed without language and publication date restrictions. This study will only include randomized controlled trials investigating the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. Two authors will independently assess all literatures, extract data, and appraise risk of bias. Any confusion between 2 authors will be cleared up by a third author through discussion. RevMan 5.3 software will be utilized to analyze the data and to perform a meta-analysis if necessary. RESULTS: This study will summarize up-to-date evidence and provide a detailed summary related to the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. CONCLUSION: This study may provide helpful evidence to determine whether or not EPSW combined SCD is effective and safety for the treatment of patients with FHN.

Efficacy of total hip arthroplasty for the treatment of patients with femoral head avascular necrosis: A protocol for systematic review and meta-analysis.

BACKGROUND: Femoral head avascular necrosis (FHAN) is a very common condition among elderly population. Previous studies have reported that total hip arthroplasty (THAP) can benefit patients with such condition. However, no study systematically addressed this topic. Thus, this study will systematically explore the efficacy and safety of THAP for the treatment of patients with FHAN. METHODS: We will search the following electronic bibliographic databases from inception to the February 29, 2020: MEDLINE, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, China National Knowledge Infrastructure, and Chinese Scientific Journal Database. Randomized controlled trials of THAP for the treatment of patients with FHAN will be included, which were reported in any language. All process of study selection, data collection, and study quality assessment will be performed independently by 2 authors independently. Any divergences will be solved by discussion with another author. RevMan 5.3 software will be carried out for data synthesis and analysis. RESULTS: This study will provide a detailed summary of current evidence related to the efficacy and safety of THAP for the treatment of patients with FHAN through assessing pain intensity of hip or knee joints, function and limitation of attacked femoral head, health-related quality of life, and complications. CONCLUSION: The findings of this study may provide helpful guidance of THAP for the treatment of patients with FHAN. SYSTEMATIC REVIEW REGISTRATION: INPLASY202040067.

High-energy extracorporeal shock wave therapy for early stage femoral head osteonecrosis: A protocol of systematic review.

BACKGROUND: Published trials reported that high-energy extracorporeal shock wave therapy (HEEPSWT) can effectively treat early stage femoral head osteonecrosis (ESFHO). However, their results are still inconsistent. Thus, this study will systematically and comprehensively explore the effectiveness and safety of HEEPSWT for ESFHO. METHODS: We will retrieve the electronic databases of Cochrane Library, EMBASE, PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature, VIP database, and China National Knowledge Infrastructure from inception to the present. All randomized controlled trials that focusing on the effectiveness and safety of HEEPSWT for ESFHO will be considered. Two researchers will undertake literature selection, information collection, and risk of bias evaluation separately. If disagreements occur, we will invite a third researcher for consultation and a final decision will be made. Cochrane risk of bias tool, and Grades of Recommendation, Assessment, Development and Evaluation will be utilized to assess the risk of bias and quality of evidence, respectively. We will perform statistical analysis using RevMan 5.3 software. RESULTS: This study will provide a detailed summary of exist evidence related to the effectiveness and safety of HEEPSWT for ESFHO. CONCLUSION: The results of this study synthesize the evidence regarding the HEEPSWT for ESFHO, which may help to guide clinical management in the future.

Comparison of clinical features and outcomes in peritoneal dialysis-associated peritonitis patients with and without diabetes: A multicenter retrospective cohort study.

BACKGROUND: The number of end-stage renal disease patients with diabetes mellitus (DM) who are undergoing peritoneal dialysis is increasing. Peritoneal dialysis-associated peritonitis (PDAP) is a serious complication of peritoneal dialysis leading to technical failure and increased mortality in patients undergoing peritoneal dialysis. The profile of clinical symptoms, distribution of pathogenic organisms, and response of PDAP to medical management in the subset of end-stage renal disease patients with DM have not been reported previously. Discrepant results have been found in long-term prognostic outcomes of PDAP in patients with DM. We inferred that DM is associated with bad outcomes in PDAP patients. AIM: To compare the clinical features and outcomes of PDAP between patients with DM and those without. METHODS: In this multicenter retrospective cohort study, we enrolled patients who had at least one episode of PDAP during the study period. The patients were followed for a median of 31.1 mo. They were divided into a DM group and a non-DM group. Clinical features, therapeutic outcomes, and long-term prognostic outcomes were compared between the two groups. Risk factors associated with therapeutic outcomes of PDAP were analyzed using multivariable logistic regression. A Cox proportional hazards model was constructed to examine the influence of DM on patient survival and incidence of technical failure. RESULTS: Overall, 373 episodes occurred in the DM group (n = 214) and 692 episodes occurred in the non-DM group (n = 395). The rates of abdominal pain and fever were similar in the two groups (P > 0.05). The DM group had more infections with coagulase-negative Staphylococcus and less infections with Escherichia coli (E. coli) as compared to the non-DM group (P < 0.05). Multivariate logistic regression analysis revealed no association between the presence of diabetes and rates of complete cure, catheter removal, PDAP-related death, or relapse of PDAP (P > 0.05). Patients in the DM group were older and had a higher burden of cardiovascular disease, with lower level of serum albumin, but a higher estimated glomerular filtration rate (P < 0.05). Cox proportional hazards model confirmed that the presence of diabetes was a significant predictor of all-cause mortality (hazard ratio = 1.531, 95% confidence interval: 1.091-2.148, P < 0.05), but did not predict the occurrence of technical failure (P > 0.05). CONCLUSION: PDAP patients with diabetes have similar symptomology and are predisposed to coagulase-negative Staphylococcus but not E. coli infection compared those without. Diabetes is associated with higher all-cause mortality but not therapeutic outcomes of PDAP.

Effectiveness of neuromuscular electrical stimulation and ibuprofen for pain caused by necrosis of the femoral head: A retrospective study.

This retrospective study analyzed the effectiveness of neuromuscular electrical stimulation (NMES) for pain relief caused by necrosis of femoral head (NFH).Totally, 80 cases of patients with NFH were analyzed and then were assigned to a treatment group or a control group in this study. Of these, 40 cases in the treatment group received ibuprofen and NMES therapy. The other 40 cases in the control group received ibuprofen alone. Cases in both groups were treated for a total of 6 weeks. The primary outcome of pain intensity was measured by a visual analog scale (VAS). The secondary outcome was assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). In addition, adverse events (AEs) were also recorded in each case. All outcomes were evaluated before and after the treatment.After treatment, patients in the treatment group showed more effectiveness in pain relief, as measured by VAS (P < .01) and WOMAC sub-pain scale (P < .01), except stiffness, as evaluated by WOMAC sub-stiffness scale (P = .07), and function, as assessed by WOMAC sub-function scale (P = .09), than patients in the control group. Additionally, no significant differences in AEs were detected between 2 groups.This study found that NMES may be helpful for pain relief in patients with NFH.

A retrospective study of acupuncture as an adjunctive therapy to topical ibuprofen for chronic knee pain due to osteoarthritis.

This retrospective study investigated the effectiveness and safety of acupuncture as an adjunctive therapy to topical ibuprofen (TIP) for patients with chronic knee pain (CKP) due to osteoarthritis.This retrospective study analyzed medical records of 84 patients with CKP due to osteoarthritis. These patients were divided into a treatment group (n = 42) and a control group (n = 42). The patients in the treatment group were treated with acupuncture plus TIP, while the subjects in the control group received TIP monotherapy. The primary effectiveness endpoint was assessed by Western Ontario and McMaster Universities osteoarthritis index (WOMAC). The secondary effectiveness endpoints were evaluated by the numeric rating scale (NRS), 12-item Short FormHealth Survey (SF-12, mainly including mental component summary [MCS], and physical component summary [PCS]), and adverse events. All patients received an 8-week treatment. All endpoints were measured pre-treatment and posttreatment.The patients who received acupuncture plus TIP showed better effectiveness in both primary endpoint of WOMAC scale (pain, P < .01; function, P < .01; and stiffness, P < .01) and secondary endpoints of NRS (P < .01), and SF-12 (MCS, P < .01; and PCS, P < .01), than patients who received TIP monotherapy. In addition, both groups had similar safety profile.The results of this study showed that the effectiveness of acupuncture plus TIP may be better than TIP monotherapy for patients with CKP due to osteoarthritis.

Therapeutic efficacy of extracorporeal shock wave combined with hyaluronic acid on knee osteoarthritis.

This retrospective study investigated the efficacy and safety of extracorporeal shock wave (EPSW) combined with hyaluronic acid (HA) for patients with knee osteoarthritis (KOA).This retrospective study included 70 patients with KOA. Of those subjects, 35 of them received EPSW combined HA, and were allocated to a treatment group, while the other 35 participants received HA alone and were allocated to a control group. Patients in both groups were treated for a total of 8 weeks. The primary outcome was measured by visual analog scale (VAS). The secondary outcomes were measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and knee injury and osteoarthritis outcome score (KOOS). In addition, adverse events (AEs) were also evaluated. All outcomes were measured before and after the treatment.After the treatment, patients in the treatment group exhibited better efficacy in VAS (P < .01), WOMAC scale (pain, P < .01; function, P < .01; and stiffness, P < .01), and KOOS scores (pain, P < .01; function in daily living, P < .01; symptoms, P < .01; sport and recreation, P < .01; and quality of life, P < .01), than patients in the control group. In addition, no significant differences regarding the AEs were found between 2 groups.The findings of this study demonstrated that the efficacy of EPSW combined with HA is superior to the HA alone for patients with KOA.

Effect of knee joint function training on joint functional rehabilitation after knee replacement.

This retrospective study investigated the effect of knee joint function training (KJFT) on joint functional rehabilitation after knee replacement in Chinese patients with severe knee osteoarthritis (KOA).Eighty-six eligible patients with severe KOA were included. Of those, 43 patients in the intervention group received KJFT and educational program, while the other 43 patients received educational program only. Primary outcome was measured by the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Secondary outcomes were measured by the visual analogue scale (VAS), and Knee Injury and Osteoarthritis Outcome Score (KOOS). All outcomes were assessed at baseline, 1 week before and 3 months after the surgery.Patients in the intervention group showed encouraging benefit neither at 1 week before nor 3 months after the surgery in all outcome measurements, including WOMAC, VAS, and KOOS, when compared with the patients in the control group.The results of this study did not show promising effect of KJFT for joint functional rehabilitation in Chinese patients with KOA after KJR.

Neuromuscular electrical stimulation for treating postpartum low back pain.

In this retrospective study, we investigated the effect of neuromuscular electrical stimulation (NMES) in patients with postpartum low back pain (PPLBP).We included 67 patients with PPLBP in this study. All patients received NMES, each session 30 minutes, 1 session weekly for a total of 4 weeks. The primary outcome was measured by the reduction in pain intensity, based on the visual analogue scale (VAS). The secondary outcomes included functional status, measured by the Roland-Morris disability questionnaire (RMDQ), and quality of life, measured by the World Health Organization Quality of Life questionnaire (WHOQOL-BREF), as well as the adverse events related to the treatment. The outcome data were evaluated at baseline and at the end of 4-week treatment.After 4-week treatment, NMES did not exert better outcomes in pain relief, measured by VAS, and functional status, measured by RMDQ compared with those before the treatment. In addition, no significant improvement in quality of life, measured by WHOQOL-BREF, compared to it before the treatment.The results of our study did not find that NMES is effective in patients with PPLBP after 4-week treatment.
