Methods : Data was collected through the Koreanstudies Information Service System(KISS). Two experts in Oriental Medicine reviewed the title and abstract in thesis, the results of searching the title, "Atopic dermatitis" and topic, "oriental medicine" at KISS, and then they handsearched Randomized Controlled Trials related to oriental medicine in Korea. According to guidelines defined by CONSORT statement, they assessed whether 37 items were followed by guidelines at yes or no answers in order to evaluate the quality as well. They assessed the definition of each item independently. After comparing, they made a decision on the item of different outcomes through an agreement with a third party. Results : Total number of randomized controlled trials in Atopic Dermatitis related to oriental medicine is eleven. A randomized controlled trial was first published in 2007. One or two papers associated it were released every year except 2013. 9 papers of them were approved by Institutional Review Board and were received written consent. The study included between 20 to 40 subjects for 2-arm parallel study design. The effect of treatment was observed for 4 to 8 weeks. On average, the number followed guidelines was 18.64 among those of 37 CONSORT statement and 50.38% of them was followed overall. Conclusion : As an interest about randomized controlled trials was increased, it was needed to care the standard providing information of CONSORT statement on randomized controlled trials related to oriental medicine in Korea. It is suggested to provide more clear information about it, so that it can be a motive for improving quality of the journal in oriental medicine.

  • Objectives : This study was designed to evaluate the feasibility of further acupuncture research as an effective and safe treatment for reducing cancer-related upper abdominal pain in patients treated with Neurolytic celiac plexus block(NCPB). Methods : This study is a randomized controlled pilot clinical trial of 3-week duration. Fourteen patients will be recruited and randomly allocated to 2 groups: an acupuncture plus NCPB group(experimental group) and a NCPB group(control group). All patients will undergo one session of NCPB, but only the experimental group will receive three acupuncture sessions a week for 2 weeks(6 in total). The primary outcome will be measured using the visual analogue scale, and the secondary outcome will be measured using the Painvision system and the consumption of additional analgesics. Assessments will be made at baseline and at 1, 2, and 3 weeks thereafter(that is, the 3-week assessment will be made 1 week after treatment cessation). Conclusions : This clinical trial will inform the design of a full-scale trial. The outcomes will provide information to facilitate the incorporation of acupuncture into existing pain management methods such as NCPB in the treatment of cancer-related upper abdominal pain patients.

  • Objectives: This study aimed to ascertain what should be considered in the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer" by analyzing the existing guidelines and clinical trials. Methods: The committee searched guidelines and clinical trials about herbal medicine for lung cancer. The searched trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparator, outcomes and trial design. Then, we compared the results of our analysis with the guidelines to identify the issues we will have to consider when making the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer". Several guidelines for anti-tumor agents and clinical trials with herbal medicine were searched on the national institution homepage. The search terms were as follows: 'lung neoplasm', 'herbal medicine', 'Medicine, Korean traditional', 'Medicine, Chinese Traditional' etc. Results: There was no guideline for clinical trial with herbal medicine for lung cancer. In addition, 7 articles were searched through database searching. All the participants had non-small cell lung cancer. The type of intervention was decoction. Comparators included conventional treatments such as chemotherapy. The outcome measurements used in the studies were quality of life, tumor response, and survival duration, etc. Safety was evaluated by recording adverse events and blood test. Conclusions: Findings were made by reviewing existing guidelines and comparing them with clinical trials for lung cancer and herbal medicinal products. These results will be utilized in the development of "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer".

  • Objectives : 1. Clinical trial for the efficacy evaluation of Korean acupuncture techniques in treating frozen shoulder. 2. Development of the standard clinical guidelines of the acupuncture treatment for the frozen shoulder. 3. Development of the new clinical protocol for the acupuncture treatments. 4. Verification of the hypothesis that treating at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints. Methods : 1. Research designed as Single blind, Randomized, Sham acupuncture controlled clinical Trial. 2. Assignment of 86 patients to one of three groups treated at nearby acupoints(group A), remote & nearby acupoints(group B), and sham points(group C) respectively. 3. Trial conducted at KIOM CRC of Dunsan oriental medical hospital, Daejeon Univ. 4. Estimation of the recovery rate of the frozen shoulder in subjects aged over 40. 5. Efficacy evaluation using VAS, SPADI, ROM and Improvement rate. Results : 1. There was no significant difference in VAS among the three groups. 2. Pain related scores in SPADI of the group B were significantly lower than those of the group A. 3. There was no significant difference in disability related scores of SPADI among the three groups. 4. External rotation of upper arm in the group B was significantly improved in comparison with that in the group C. 5. Abduction of upper arm in group A was improved with weak statistical significance in comparison with that in the group C. Conclusion : Acupuncture at both the remote and the nearby acupoints according to the meridian theory is effective to improve external rotation of frozen shoulder, and acupuncture at the nearby acupoints is effective to improve adduction of frozen shoulder. However it is not clear that acupuncture treatment at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints in the treatment of frozen shoulder. Since our study was a short term trial, a long term trial for a more precise evaluation of acupuncture treatment for frozen shoulder will be needed in the future.

  • Objectives : To review and summarize the existing evidence on acupuncture treatment for cancer and cancer related symptoms. Methods: Literature searches were made through domestic and international databases. Data were extracted according to pre-defined criteria. The methodological quality was assessed using the Modified Jadad scale. Results: Seven studies were included. Two of the studies were high in methodological quality. One study concerning acupuncture treatment for cancerous dyspnea reported insignificant differences between the treatment group and placebo group. The other study concerning auricular acupuncture for cancer related pain showed significant pain relief compared with the control group. All the other studies were non-blinded or uncontrolled trials. Conclusion : The hypothesis that acupuncture may be effective for the treatment of cancer is not supported by the data in recent clinical trials. More accurately designed randomized control trials (RCT) are needed.

  • Objectives: To investigate the effects of acupuncture at GV20 and EX-HN1 on cerebral blood flow (CBF) velocity and cerebrovascular reactivity (CVR) in the middle cerebral arteries (MCA) and anterior cerebral arteries (ACA) and to compare the effects to acupuncture at GV20. Methods: The study was a randomized, crossover trial that included 10 healthy men aged 20 to 29 years who underwent acupuncture treatment four times with a washout period of one week. The CBF velocity and CVR were measured by transcranial Doppler sonography (TCD) on both MCAs at the first and second visits, and both ACAs at the third and fourth visits. Participants were randomly assigned to one of two groups (A and B) before the first and third visits. Group A received two phases of acupuncture intervention at a single GV20 point and a combination of GV20 and EX-HN1 acupoints. Group B received the same interventions, but in the reverse order. Results: The increase in CO2 reactivity was significantly higher for the combination acupoints of GV20 and EX-HN1 than for the GV20 single acupoint in both MCAs (Right: 136 to 178, p=0.017; Left: 127 to 191, p=0.017) and ACAs (Right: 133 to 158, p=0.013; Left: 122 to 168, p=0.025). No significant change was noted in the corrected velocity at PETCO2 40 mmHg, blood pressure, or heart rate. Conclusions: The findings suggest that improvement of the CBF in the MCA and ACA after GV20 acupuncture increases when acupuncture is also performed at EX-HN1. These results clinically support the combined use of EX-HN1 and GV20 to treat disorders of MCA and ACA circulation.

  • Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard diagnostic method for mediastinal and hilar lymphadenopathy. Although rare, fatal infectious complications can occur following EBUS-TBNA. However, to date, there is a lack of effective preventive strategies to reduce these complications. We started a trial to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Methods: This study is a single-center, parallel-group, assessor-blinded randomized controlled trial (RCT). We will enroll 112 adult participants undergoing EBUS-TBNA using a convex probe, and randomly assign them to two groups at a 1:1 ratio. The intervention group will gargle for 1 minute with 100 mL of 0.12% chlorhexidine gluconate before EBUS-TBNA, while the control group will have no mouthrinse before the procedure. Immediately after completion of EBUS-TBNA on all targeted lesions with an aspiration needle, a needle wash sample will be taken by instilling 5 mL of sterile saline into the used needle. The primary outcome is colony forming unit (CFU) counts in aerobic cultures of the needle wash samples. Secondary outcomes are CFU counts in anaerobic cultures, fever within 24 hours after EBUS-TBNA, and infectious complications within 4 weeks after EBUS-TBNA. Conclusion: This trial was designed as the first RCT to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Results from this trial can provide clinical evidence for a simple, safe, and cost-effective strategy to prevent infectious complications following EBUS-TBNA (ClinicalTrials.gov ID: NCT04718922, registered on 22 January 2021).

  • Data from clinical studies are needed for psychiatrists to make quick and scientific decisions based on the best available evidence in clinical settings. Various methods of clinical studies are useful for clinicians to have reliable answers to unmet clinical needs. Although randomized controlled trials may provide high-quality information about major issues, well-designed, naturalistic and observational studies often give us unbiased explanation for real-world phenomena. Adequate selection of clinical variables and appropriate number of participants are key factors of well-designed clinical studies. Statistical methods can add an extra dimension to initial design of clinical studies. Given ethical issues in clinical studies on psychiatric disorders, special regards should be paid to participants' ability to provide informed consents. New strategies of clinical studies need to be developed to meet clinical needs and protect the rights and welfare of study participants.

  • Objectives : Though there were many clinical studies of acupuncture effects they didn't have appropriate control group or use another therapy for control group. So, we didn't say it was true acupuncture effect, though subjects in clinical study improved. Recently several sham needles for control group were developed and validated. This study aimed at summarizing the validation studies of these needles and evaluating the control group of the acupuncture clinical study. Methods : Computerized literature searches were performed using 'acupuncture' and 'placebo or sham' with a limitation of the results to RCTs in Pubmed, Sciencedirect, NDSL, KISS, RISS. Data were extracted regarding study design, sample size, acupuncture point, stimulation form, credibility testing. And We have examined 106 acupuncture clinical studies published by Pubmed from January 1, 2005 to April 30, 2008. Data were extracted author's country, subject of study, type of study groups, type of control groups, type of blinding, difference between the results in the control groups. Results : Streitberger's placebo needle, Fink's sham needle, Park sham needle, Kim sham needle were developed. They were validated at domestic and abroad. But the results were deviation depending on the each of the researcher. They has shown that sample, acupuncture points, experiences or knowledge of acupuncture dependent on the results. Recent three years, acupuncture clinical trial had different results. Significant differences between Study group and control group emerged from using other therapy or non-treatment for control group. Many study has no significant differences using sham acupuncture for control groups. Conclusions : Acupuncture clinical studies need to meet several requirements. First of all, they require the basics of randomized controlled clinical studies such as blinding and the accurate implementation and description of randomization. And also need to research the unique circumstances of these studies such as the development of sham acupuncture and blinding method which differs from other clinical trials.

  • Purpose: This report aims to administer methodologic issues around recently conducted multicenter study for evaluating the effects of acupuncture on menopusal hot flashes and discuss practical issues for further implementation of acupuncture clinical trial for hot flashes. Methods: Study process were mentioned, and issues related to avoiding risk of bias, designing appropriate control group, optimal outcome measurement, potential different effects of menopausal status on study outcomes, and suggestions for developing future clinical trials are discussed. Results: Shortcomings of our multicenter study include lack of allocation concealment and assessor blinding, subjective outcome measurement, short-term follow-up, and fixed acupuncture regimen despite pragmatic purpose of this study. Improving trial design, using objective or validated outcomes, assessing long-term effects of acupuncture, and individualizing acupuncture regimen are needed in future clinical trials. Conclusion: We expect these practical discussions to enable researchers to plan and develop future well-designed clinical trials for evaluating the effects of acupuncture on hot flashes or other women's health issues.
