  • Background: Local anesthetics alone or in combination with adjuncts, such as oral medications, have routinely been used for pain control during endodontic treatment. The best clinical choice amongst the vast numbers of agents and techniques available for pain control for irreversible pulpitis is unclear. This network meta-analysis combined the available evidence on agents and techniques for pulpal anesthesia in the maxilla and mandible, in order to identify the best amongst these approaches statistically, as a basis for future clinical trials. Methods: Randomized trials in MEDLINE, DARE, and COCHRANE databases were screened based on inclusion criteria and data were extracted. Heterogeneity was assessed and odds ratios were used to estimate effects. Inconsistencies between direct and indirect pooled estimates were evaluated by H-statistics. The Grading of Recommendation, Assessment, Development, and Evaluation working group approach was used to assess evidence quality. Results: Sixty-two studies (nine studies in the maxilla and 53 studies in the mandible) were included in the meta-analysis. Increased mandibular pulpal anesthesia success was observed on premedication with aceclofenac + paracetamol or supplemental 4% articaine buccal infiltration or ibuprofen+paracetamol premedication, all the above mentioned with 2% lignocaine inferior alveolar nerve block (IANB). No significant difference was noted for any of the agents investigated in terms of the success rate of maxillary pulpal anesthesia. Conclusion: Direct and indirect comparisons indicated that some combinations of IANB with premedication and/or supplemental infiltration had a greater chance of producing successful mandibular pulpal anesthesia. No ideal technique for maxillary anesthesia emerged. Randomized clinical trials with increased sample size may be needed to provide more conclusive data. Our findings suggest that further high-quality studies are required in order to provide definitive direction to clinicians regarding the best agents and techniques to use for mandibular and maxillary anesthesia for irreversible pulpitis.

  • Purpose: The purpose of this study is to assess the effectiveness of short-wave therapy (SWT) for treatment of knee osteoarthritis (OA) as compared to placebo and control, and to assess the question of whether the effects are related to the mode, dosage, and application method. Methods: We searched randomized, placebo-controlled trials using electronic databases. We also manually reviewed sources in order to identify additional relevant studies. Results: Eight studies (597 participants) with OA were included in the meta-analysis. Pulse SWT had a significant effect on pain relief compared with control treatment, while did not favour compared with the placebo group. Pulse SWT had a significant effect on functional improvement compared with control and placebo treatment. Continuous SWT had no effect on pain relief and functional improvement. Capacitive SWT a significant effect on pain relief, functional improvement, and muscle strength. Continuous and capacitive SWT had increased muscle strength significantly. We found no clinical significance of all outcomes except pain and functional improvement in pulsed SWT with low dose. There was no difference in adverse events. None of the participants experienced any serious adverse events. Conclusion: Low dose pulsed SWT provided a short-term clinical benefit for pain relief and functional improvement. Pulsed SWD with low and high dose had effects on pain and function. There seems to be a placebo effect. We found significant effects on pain and function in capacitive SWT. Despite some positive findings, this analysis lacked data on how effectiveness is affected by mode, dosage, and application method of SWT. Further well-designed clinical studies are required in order to confirm the effectiveness of SWT.

  • Objectives : The aim of this study is to assess the quantity and quality of randomized controlled clinical trials(RCTs) published in the journal of oriental rehabilitation medicine(JORM). Methods : After searching RCTs from all the articles published in the JORM from the inception(1991) to Oct, 2012, quantity assessment were made on the study design, sample size, main intervention, intervention versus control design and medical condition. Quality assessment were made on the cochrane risk of bias(RoB) check list. Assessment was performed by 2 independent reviewers and disagreement was discussed based on concensus of all authors. Results : Among the 1013 articles, total 59 RCTs were published. First RCT was published in 1994. 49 RCTs were parallel 2-arm designed. Average sample size was 35.1 per study and 16.3 per arm. The most common medical condition is musculoskeletal disease(30.5%). Quality from cochrane RoB was generally low. Conclusions : Though RCTs published in JORM were increasing, the quality remains low. Researchers should make a effort to follow the RoB checklists and improve the quantity and quality of studies.

  • Objective: To investigate outcomes of stimulated IVF cycles in which GnRH antagonist was omitted on the ovulation triggering day. Methods: A total of 86 women who underwent controlled ovarian hyperstimulation with recombinant FSH and GnRH antagonist flexible multiple-dose protocols were recruited and prospectively randomized into the conventional group (group A) or cessation group (group B). The GnRH antagonist, 0.25 mg/day of cetrorelix, was started when the leading follicle reached 14 mm in diameter and was continuously administered until the hCG triggering day (group A, 43 cycles) or until the day before hCG administration (group B, 43 cycles). The maturity of oocytes, fertilization rate, embryo quality, and implantation and clinical pregnancy rates were evaluated. Results: The duration of ovarian stimulation, total dose of gonadotropins, serum estradiol levels on hCG administration day, and number of oocytes retrieved were not significantly different between the two groups. The total dose of GnRH antagonist was significantly lower in group B than group A ($2.5{\pm}0.9$ vs. $3.2{\pm}0.8$ ampoules, p<0.05). There was no premature luteinization in any of the subjects. The proportion of mature oocytes and fertilization rate were not significantly different in group B than group A (70.7% vs. 66.7%; 71.1% vs. 66.4%, respectively). There were no significant differences in the implantation or clinical pregnancy rates. Conclusion: Our prospective randomized study suggested that cessation of GnRH antagonist on the hCG administration day during a flexible multiple-dose protocol could reduce the total dose of GnRH antagonist without compromising its effects on pregnancy rates.

  • Objectives: The purpose of this review was to overview and evaluate the efficacy of electroacupunture for women with polycystic ovarian syndrome (PCOS) Methods: Relevant randomized controlled studies (RCTs) were identified by database searches in PubMED, EMBASE, OASIS, and Google scholar, up to May 2018. Data were extracted regarding hyperandrogenism, obesity and hyperinsulinemia indices. The risk of bias was assessed. Results: Five RCTs were included for analysis. In one RCT, electroacupuncture group had significantly lower free testosterone and testosterone, compared to no treatment group. However, The other RCTs showed no significant difference between two groups. For LH/FSH, Ferriman Gallway score, anti-mullerian hormone, body mass index, weight and waist, and insulin, electroacupuncture group showed no significant difference, compared to physical exercise, no treatment, and sham acupuncture group. Conclusions: Only a limited number of RCTs have been reported. At present, there is insufficient evidence to support the use of electroacupuncture for treatment of PCOS.
