Objectives To assess the effectiveness and safety of any form of therapy compared with glucocorticoid for the treatment of oral lichen planus. Method The Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMbase (1966-2007), CBM (1978-2005), CNKI (1989-2007), and VIP (1989-2007) were searched for randomized controlled trials or quasi-randomized controlled trials. Quality assessment and data extraction were performed by two reviewers independently. Meta-analysis was performed for the results of homogeneous studies by RevMan 4.2.9 software.Results Finally, 14 studies involving 9 therapy methods were included. Four studies were concerned with cyclosporine.We performed a meta-analysis of 3 studies. The results showed there was no statistically significant difference in the curative effect of cyclosporine and the steroid with RR 2.94 and 95%CI 1.03 to 9.97. The results showed that the curative effect of total glucosides of paenia plus topical application of triamcinolone acetonide (RR0.21, 95%CI 0.10 to 0.44),tacrolimu (RR 0.18 and 95%CI 0.05 to 0.72), and pimecrolimus (WMD –0.50 and 95%CI –0.85 to –0.15) were better than glucocorticoid. There was a statistically significant difference between fluocinolone acetonide and retinoic acid in terms of curative effect with RR 3.20 and 95%CI 1.03 to 9.97. The curative effect of mesalazine (RR 0.42 and 95%CI 0.05 to 3.54), Mycostatin paste plus desamethasone paste (RR 1.23 and 95%CI 0.93 to 1.61), triamcinolone acetonide plus vitamin B12 ( RR 0.50 and 95%CI 0.05 to 4.94), chitin (RR 1.30 and 95%CI 0.86 to 1.96) was similar with that of glucocorticoid.Conclusion Statistical analysis showed the curative effect of total glucosides of paenia combined with triamcinoloneacetonide is better than glucocorticoid. Due to the mistakes of theincluded studies designs,,further high-quality,largescale randomized controlled trials are required to confirm the effectiveness and safety of this therapy method.
Objective To evaluate the efficacy and safety of percutaneous ethanol injection for hepatocellular carcinomas of 3 cm or less. Methods Randomized controlled trials (RCTs) from the Cochrane Controlled Trials Register (Cochrane Library issue 2, 2008), PubMed (1966 to 2008), EMbase (1966 to 2008), CBMdisc (1978 to 2008), and CNKI (1979 to 2008) were electronically searched. We hand searched related published and unpublished data and their references. Randomized controlled trials of percutaneous ethanol injection to treat hepatocellular carcinomas of 3 cm or less were included. Data were extracted and evaluated by two reviewers independently using a designed extraction form. RevMan 4.2.10 software was used for data analysis. Results Seven RCTs involving 891 patients were included. We conducted subgroup analyses based on outcome measures and interventions. Compared with RFA, for treatment of hepatocellular carcinomas of 3 cm or less, PEI showed statistical differences in one and three-year survival rates and one and three-year local recurrence rates after treatment(RR=0.95, 95%CI 0.91 to 1.00; RR=0.80, 95%CI 0.71 to 0.91; RR=2.18, 95%CI 1.11 to 4.30; RR=2.59, 95%CI 1.55 to 4.32). As for hepatocellular carcinomas of 2-3 cm, PEI showed statistical difference in three year cancer free survival rates after treatment (RR=0.47, 95%CI 0.24 to 0.93) .Conclusion Considering the relatively poor quality of most included trials and small sample size, insufficient evidence was obtained in this systematic review. Therefore, more randomized controlled trials with high quality are still needed to assess and verify the efficacy and safety of this treatment.
Objective To compare the effectiveness between unilateral and bilateral percutaneous kyphoplasty (PKP) in the treatment of Kümmell disease. Methods The clinical data of 45 patients with Kümmell disease that met the criteria between January 2014 and February 2016 were analyzed retrospectively. Among them, 26 cases were treated by unilateral PKP (unilateral group), 19 cases were treated by bilateral PKP (bilateral group). There was no significant difference in gender, age, disease duration, injured vertebral segment, bone mineral density (T value), and the preoperative visual analogue scale (VAS) score, Oswestry disability index (ODI), anterior vertebral height, and kyphosis Cobb angle between 2 groups (P>0.05). The operation time, intraoperative fluoroscopy times, amount of injected bone cement, and hospitalization time were recorded, and the situation of bone cement leakage was observed. The VAS score, ODI, anterior vertebral height, and kyphosis Cobb angle were evaluated before operation, at 1 day after operation, and at last follow-up. Results Bone cement leakage during the operation were found in 4 cases (15.38%) of unilateral group and 3 cases (15.79%) of bilateral group without obvious neurological symptoms; there was no significant difference in the incidence of bone cement leakage between 2 groups (χ2=0.000, P=1.000). The operation time, intraoperative fluoroscopy times, and amount of injected bone cement in the unilateral group were significantly lower than those in the bilateral group (P<0.05); but there was no significant difference in the hospitalization time between 2 groups (P>0.05). The X-ray film examination showed that there was no pulmonary embolism in all patients at 1 day after operation. All the patients were followed up 12-24 months, with an average of 16.4 months. There was no complication such as vertebral re-fracture or cement block displacement in the injured vertebra. The VAS score, ODI, anterior vertebral height, and kyphosis Cobb angle at 1 day after operation and at last follow-up were significantly improved when compared with preoperative values in 2 groups (P<0.05); the VAS score and ODI in 2 groups were further reduced at last follow-up when compared with the value at 1 day after operation (P<0.05), but the anterior vertebral height and kyphosis Cobb angle in 2 groups at last follow-up did not change significantly (P>0.05). There was no significant difference in above indexes at 1 day after operation and at last follow-up between 2 groups (P>0.05). Conclusion Both unilateral and bilateral PKP can achieve good effectiveness in treatment of Kümmell disease. But the unilateral puncture technique possesses advantages such as shorter operation time, less radiation dose, and less amount of injected bone cement.
ObjectiveTo compare the effectiveness of short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty in treatment of stage Ⅲ Kümmell disease.MethodsA clinical data of 44 patients with stage Ⅲ Kümmell disease met the selection criteria between January 2014 and December 2017 was retrospectively analyzed. Eighteen cases were treated with short-segment bone cement-augmented fixation combined with vertebroplasty (short-segment group) and 26 cases were treated with long-segment bone cement-augmented fixation combined with vertebroplasty (long-segment group). There was no significant difference in gender, age, disease duration, fracture segment, bone mineral density (T value), Frankle grading, and preoperative pain visual analogue scale (VAS) score, Oswestry disability index (ODI), anterior edge height of injured vertebrae, kyphosis Cobb angle, and thoracolumbar kyphosis (TLK) between the two groups (P>0.05). The operation time, intraoperative blood loss, bone cement injection volume, bone cement leakage rate, VAS score, ODI, anterior edge height of injured vertebrae, kyphosis Cobb angle, and TLK were compared between the two groups.ResultsThe operation time and the intraoperative blood loss in the short- segment group were significant lower than those in the long-segment group (P<0.05). There was no significant difference in bone cement injection volume and bone cement leakage rate between the two groups (P>0.05). All patients were followed up 12-36 months, with an average of 24.4 months. The VAS score, ODI, anterior edge height of injured vertebrae, kyphosis Cobb angle, and TLK significantly improved at 1 week after operation and last follow-up in the two groups (P<0.05), there was no significant difference between the two groups (P>0.05). At last follow-up, the neurological function of the two groups recovered, and there was no significant difference in Frankle grading between the two groups (P>0.05). There were 3 cases (16.67%) of non-surgical vertebral fractures in the short-segment group and 6 cases (23.08%) in the long-segment group, showing no significant difference between the two groups (P>0.05). Bone rejection occurred in 1 case in the short-segment group, and neither internal fixation failure nor collapse of the injured vertebrae occurred during follow-up.ConclusionBoth short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty can achieve good effectiveness in treatment of stage Ⅲ Kümmell disease, and can maintain the height of the injured vertebra and prevent the collapse of the injured vertebra. Compared with long-segment fixation, short-segment fixation has the advantages of shorter operation time and less intraoperative bleeding.
ObjectiveTo investigate the effectiveness of Vesselplasty and percutaneous kyphoplasty (PKP) in treatment of Kümmell disease.MethodsBetween January 2015 and December 2018, 63 patients with Kümmell disease were treated. Among them, 28 cases were treated with Vesselplasty (Vesselplasty group) and 35 cases were treated with PKP (PKP group). There was no significant difference in gender, age, disease duration, bone mineral density (T value), fracture distribution, and preoperative pain visual analogue scale (VAS) score, Oswestry Disability Index (ODI), anterior height of injured vertebrae, and kyphosis Cobb angle between the two groups (P>0.05). The operation time, intraoperative fluoroscopy time, bone cement injection volume, the leakage rate of bone cement, the diffusion area ratio of bone cement, and the complications of the two groups were recorded. VAS score, ODI, anterior height of injured vertebrae, and kyphosis Cobb angle were compared between the two groups before operation and at 1 day after operation and last follow-up.ResultsAll patients of the two groups were followed up 12-36 months, with an average of 24.2 months. The operation time, intraoperative fluoroscopy time, bone cement injection volume, and diffusion area ratio of bone cement were significantly lower in the Vesselplasty group than in the PKP group (P<0.05). The leakage rate of bone cement was significantly lower in the Vesselplasty group (7.14%) than in the PKP group (34.29%) (χ2=5.153, P=0.023). At 1 day after operation and last follow-up, the VAS score, ODI, anterior height of injured vertebrae, and kyphosis Cobb angle of the two groups were superior to those before operation (P<0.05), and no significant difference between the two groups (P>0.05). During the follow-up, there was no re-collapse of vertebrae, and the adjacent vertebrae fracture occurred in 2 cases of the Vesselplasty group and 5 cases of PKP group. There was no significant difference in the incidence of adjacent vertebrae fracture between the Vesselplasty group (7.14%) and the PKP group (14.29%) (χ2=0.243, P=0.622).ConclusionVesselplasty and PKP have similar effectiveness in the treatment of Kümmell disease. They can effectively relieve the pain symptoms, improve the quality of life, partially restore the height of injured vertebrae, and correct kyphosis. But the Vesselplasty has the advantages of shorter operation time, less intraoperative fluoroscopy time, and less bone cement leakage.
