  • Thoracic surgeons need to be aware of several important points regarding intraoperative lymph node dissection during surgery for non-small cell lung cancer with ground-glass opacities. The first point relates to the need for lymph node dissection during sublobar resection. Since even patients undergoing sublobar resection may benefit from lymph node dissection, it should be selectively performed according to adequate indications, which require further study. Second, there seems to be no difference in postoperative morbidity between systematic sampling and systematic dissection, but the survival benefit from systematic dissection remains unclear. The results of randomized controlled trials on this topic are conflicting, and their evidence is jeopardized by a high risk of bias in terms of the study design. Therefore, further randomized controlled trials with a sound design should investigate this issue. Third, more favorable survival outcomes tend to be positively associated with the number of examined lymph nodes. Minimum requirements for the number of examined lymph nodes in non-small cell lung cancer should be defined in the future. Finally, lobe-specific lymph node dissection does not have a negative prognostic impact. It should not be routinely performed, but it can be recommended in selected patients with smaller, less invasive tumors. Results from an ongoing randomized controlled trial on this topic should be awaited.

  • Objective: Falling is one of main accident to facilitate the physical injuries in order adults. The purpose of the systematic review was to determine the effects of postural balance training whether the recovery of falls in elderly with normal physical function or not throughout summing the selected studies quantitatively. Design: A systematic review Methods: MEDLINE and other four databases were searched up to April 20, 2021 and randomized controlled trials (RCTs) evaluating postural balance approaches on fall risks in elderly. The researched studies excluded the double studies, titles and abstract, and finally full-reported study. The selected RCTs studies were extracted characteristics of the studies and summary of results based on PICOS-SD (population, intervention, comparison, outcomes, and setting- study design) model to synthesize the papers qualitatively. Results: The review involved 22 RCT reports with 4,847 community older adults aged 65 years or over. Nineteen of the selected RCT studies reported dual or multimodal exercises show the beneficial effect for older adults compared to one-type treatment or no intervention. All of selected showed low risk in the selection, attrition, and reporting bias. However, detection bias showed low risk at 75% records of the involved RCTs and performance bias was low risk at only three records. Conclusions: The results of the systematic review propose that a standardized therapeutic approach and the intensity are needed for improving risk of falls in older adults.

  • Objectives The purpose of this thesis is to compare and analyze outcomes of case studies and controlled studies about Hwangryunhaedok-tang (HHT) pharmacopuncture in clinical studies. Based on these studies reporting clinical effects by using HHT pharmacopuncture, we object to deduct the comparative review in applying clinical disorders limitedly. And conclusionally, by using this comparative review, we aim to make the fine evidence in treating clinical specific diseases. Methods We searched 106 studies about HHT pharmacopuncture from 6 Korean web databases by using in Korean word 'Hwangryunhaedok-tang pharmacopuncture'. This search had been progressed throughout 1 month (January, 2019). There was 106 thesis and we excluded studies that are not related to HHT pharmacopuncture, experimental research, not the case report or randomized controlled trials, non-randomized controlled trials, not using HHT pharmacopuncture, not using only one pharmacopuncture, and not using HHT pharmacopuncture for major treating method. As a result, 39 thesis are selected as a population. Results We analyzed 34 case reports and 5 controlled studies. As the final outcome, HHT pharmacopuncture was used in musculoskeletal diseases, dermatopathy, and 32 specific diseases. Conclusions After analyzing 39 studies, effective symptom changes clinically and statistically by using HHT pharmacopuncture herbal acupuncture were identified. However, these thesis designs were reported deficiently in many parts such as not excluding other confounding variables. After modifying defects of thesis design and conduct study, it can play a role as the evidence using HHT pharmacopuncture more precisely.

  • Objectives: This study aimed to evaluate any clinical studies regarding rhinitis published by the Korean Oriental Medical Society and its sub-societies for future rigorous clinical research. Methods: Every article relevant to rhinitis was initially obtained from journals of the Korean Oriental Medical Society and its sub-societies by electronic search at journal web sites or manual searches. Journals were limited to those registered with the Korea Research Foundation. From initial findings, two independent reviewers selected clinical articles and these articles were further analyzed separately by predefined criteria according to prospective and retrospective studies. For prospective studies, quality assessment was also conducted. Results: From 36 initially obtained articles, 17 were finally analyzed. 2 articles were randomized controlled studies, 6 articles were prospective whereas 9 were retrospective. In the prospective articles, there were no randomized controlled trials and the other non-randomized studies had no control group with several problems of quality regarding pre-calculated study size and unbiased assessment. None of the retrospective studies described rhinitis diagnosis objectively and outcome measures were either non-relevant to rhinitis or non-validated. Conclusions: Further well-designed randomized controlled studies for rhinitis are mandatory and more rigorous non-randomized controlled studies should be conducted.

  • Objectives : This is a pilot study for a large randomized controlled trial to investigate the efficacy and safety of a newly developed contrast therapy device-- alternating topical heat and cold -- for patients with chronic low back pain. The main objective of this study is to confirm the feasibility of the study design. Methods : The design was a randomized, 2-arm, parallel-group, single-blind, placebo controlled trial. Patients in each group received real or sham contrast therapy in an acupuncture point 10 times over four weeks. The primary outcome measure was pain intensity on a 100-mm visual analogue scale (VAS). The secondary outcomes were back-related dysfunction based on the Oswestry Disability Index (ODI), the Roland-Morris disability questionnaire (RMDQ), and range of motion of lumbar spine based on the modified Schober test (mSchober test), Finger-to-Floor distance (FTF distance), and Finger-to-Thigh distraction (FTT distraction). Results : A total of 30 subjects with chronic low back pain were randomly assigned to a contrast therapy group (n=15) or a sham group (n=15). A repeated-measures analysis of variance showed statistically significant group time interaction for VAS, RMDQ, mSchober test and FTF distance (p<0.05). The treatment group showed significant improvement in pain intensity and functional disability as compared to the sham group. Conclusion : Contrast therapy may be an effective and safe treatment for chronic low back pain.

  • Objectives The purpose of this study is to present evidence by analyzing the research trends in acupuncture treatment in the last 10 years for thromboangiitis obliterans. Methods Randomized controlled trials about acupuncture on thromboangiitis obliterans were searched China National Knowledge Infrastructure (CNKI), PubMed, EMBASE, Cochrane Library, Oriental Medicine Advanced Searching Integrated System (OASIS), ScienceON, Koreanstudies Information Service System (KISS) and Research Information Sharing Service (RISS) from January 1, 2011 to November 13, 2021. Only randomized controlled trials were selected and we assessed the risk of bias (RoB) according to the revised Cochrane RoB2 criteria. Results A total of 5 randomized controlled trials (RCTs) were selected in this review and all were conducted in China. A total of 326 participants were in 5 RCTs. SP10, ST36, GB34 was the most commonly used treatment point. There were four types of acupuncture used: manual acupuncture, embedding acupuncture, pharmacopuncture, electroacupuncture. The most commonly used indicator for evaluation was the total efficacy rate, and all five studies were significantly higher. Conclusions All selected studies showed the group treated with acupuncture treatments on thromboangiitis obliterans were statistically more effective than the control group. However, the number of studies is too small and the interpretation of the results is limited due to the inclusion of subjective evaluation. So more objective and systematic studies should be conducted continuously.
