  • The purpose of the review article was to summarize and discuss the available information concerning the effect of bleaching on human teeth and reduced treatment on negative influence. Tooth bleaching effect was differ from extent of concentration and application period of a tooth bleaching agent, certainly full knowledge prior treatment about adverse effect possible appearance and follow clinical treatment for the least reduce. It remains unclear in how far those observation may result in significant adverse effect under clinical conditions. Nevertheless, further investigation are necessary to elucidate these aspect more precisely. The findings of the study were as follows : 1. It is recommended to delay placement of restorations after termination of bleaching therapy for at least 1-3 weeks. 2. Reduced negative influence that is clinical feasibility of catalase in protecting bleached surface against Oxygen radical. 3. The residual peroxide in tooth after bleaching seems to be removed by gradual diffusion and it may be possible to eliminate the adverse effect on tooth by using water displacement solution, ethylalcohol and aceton including it for effective removal of free radical oxygen.

  • Objectives : The aim of this study is to review the combination effects and adverse effects of Yerba Mate (Ilex paraguariensis) on the treatment of obesity. Methods : Four databases were searched, including Pubmed, National assembly library, RISS4u, and NDSL, for studies published before March 31, 2016 using the keywords 'yerba mate', 'Ilex paraguariensis', and those related to 'obesity'. Clinical trials, and both in vivo and in vitro studies were classified according to the following categories: publication year, nationality, types and composition of test compounds, combination effects, adverse effects, and safety. Results : A total of 16 articles (14 clinical trials, one in vivo, one in vitro) were included in the analysis. Combination effects were reported from six YGD (Yerba Mate, Guarana, Damiana, Zotrim), five Meltdown, one Shred-matrix, one DBX (DymaBurn Xtreme), one XSIII research study, and adverse effects were reported from two YGD (Zotrim), four Meltdown, one Shred-matrix and one MetEF research study. YGD and Shred-matrix increased satiety while YGD and MetEF had adverse gastrointestinal effects potentially due to guarana. Meltdown and Shred-matrix increased energy expenditure and fat oxidation and had the adverse effects of increased heart rate and blood pressure due to the thermogenic effect of caffeine and yohimbine. DBX increased resting energy expenditure but no difference was observed in respiratory exchange ratio. XSIII reduced body weight gain and food intake more than each of the extracts did on their own. Conclusion : Taken together, the combination effects and adverse effects differed according to the composition of test compounds and the ratio of ingredients. Multicomponent approaches should be used for treating multifactorial diseases such as obesity. As a general conclusion, there is a place for a combination of herbal components including yerba mate, based on the principle of Kun-Shin-Choa-Sa for the treatment of obesity.

  • Background: Continuous caudal epidural block is a useful method in postoperative pain control after perianal surgery. But caudal epidural block has the potential of developing adverse effects such as urinary retention. The goal of this study is to evaluate the analgesic and adverse effect of bupivacaine with fentanyl through continuous caudal epidural block in relation to the concentration of bupivacaine. Methods: We divided the patients randomly into two groups. For group I(n=25) postoperative pain was controlled by continuous caudal epidural infusion at the rate of 4 ml/hr of 0.0625% bupivacaine with 3 ${\mu}g$/ml fentanyl: group II(n=14), 0.125% bupivacaine with 3 ${\mu}g$/ml fentanyl, respectively, for duration of 48 hours via epidural catheter. We evaluated pain scores with visual analogue scales at 30 mins, 6 hrs, 12 hrs, 24 hrs and 48 hrs after the operation and the incidence of adverse effect, especially urinary retention, for each group. Results: There were no significant differences in the pain score between group I and II. Urinary retention developed in 9 patients(36%) of group I, and 11 patients (78.6%) of group II. Other adverse effects such as pruritus, nausea, vomiting and respiratory depression developed in few patients. Conclusions: While performing continuous caudal epidural block with mixture of bupivacaine and fentanyl after the perianal surgery, we conclude 0.0625% bupivacaine solution is preferable to 0.125% bupivacaine solution because 0.0625% solution resulted in satisfactory analgesia with minimal incidence of adverse effect.

  • Objectives : This study aimed to evaluate adverse outcome associated with acupotomy and compare it with that of acupuncture. Methods : We retrospectively analyzed the chart records of 71 patients who received acupotomy at Daemyung Korean medical clinic from January 7, 2020 to March 6, 2020. We divided the acupotomy treatment area into 10, including the head, hand, chest, knees, shoulders, low back, neck, upper extremities, thighs, and feet. Furthermore, we investigated the adverse effect of acupotomy on those areas after treatment. Data were analyzed using descriptive statistics, and frequency analysis. Results : 'Bruise of specific region' accounted for the largest portion with 29 cases, followed by 24 cases of 'feeling tired and sleepy' and 17 cases of 'itch'. There were 16 cases of 'sustained pain' at the area of treatment, 11 cases of 'fatigue', 5 cases of 'swelling', 5 cases of 'dizziness', 4 cases of 'hematoma'. There were 3 cases of 'vertigo' and 2 cases of 'parathesia' and 'wide bruises', 'headache', 'gastric discomfort', 'bleeding', and 'skin rash' each. There was one case each that experienced 'unclear pronunciation', 'nausea', 'abnormal sweating', 'vomiting' and 'emotional/psychological reactions'. Conclusions : Adverse outcomes associated with acupotomy were mostly 'bruise of specific region', 'feeling tired and sleepy', 'itch', 'sustatained pain', and 'fatigue'. However, no adverse outcome or irreversible damage that have a serious effect on the body were observed.

  • This study applies the concepts of sociotechnical theory and role theory in order to verify the effects of stress (that is, technostress) created from information and computer technology (ICT) concerning role stress and performance. We suggest diverse perspectives concerning the elements leading to technostress along with the stress-creating process of ICT among organizational members. The following four major hypotheses are proposed: (1) Technostress is positively related to role stress (e.g., conflict and overload of roles), adverse psychological outcomes, and adverse IS use related outcomes, (2) Role conflict is positively related to adverse psychological outcomes and adverse IS use related outcomes, (3) Role overload is positively related to adverse psychological outcomes and adverse IS use related outcomes, and (4) Innovation support will play as a moderator between technostress, roles tress, adverse psychological outcomes and adverse IS use related outcomes. A partial least square (PLS) with data gathered data from ICT users of organizations was used to verify the proposed hypotheses. The results supported our claims excluding the hypothesis associated to the relationship between technostress and role stress. We suggest a theoretical implication based on the verification of technostress related to the current concept of stress experienced by individuals within organizations. We also propose that a practical implication concerning the opposite effect of technostress, can be utilized as a method of reducing role stress, and suggests a diagnostic tool for assessing the degree of technostress within organizations.

  • Objectives: This study was aimed to develop a pharmacovigilance practice training course for future doctors of Korean medicine, the graduate students of a college of Korean medicine, and to verify the educational effect of the curriculum. Methods: Fifty-six students were given a training course designed as follows: 1) pre-class homework (basic theory self-study, online course, causality assessment, and adverse event reporting simulation); 2) in-class: homework submission and case discussion; 3) after-class: homework revision and resubmission. An online survey to assess the change of the level of basic knowledge and attitudes toward pharmacovigilance, the willingness to report adverse events, and self-efficacy for the causality assessment and adverse event reporting was conducted before and after education. Results: The survey participation rate was 96.5% in pre-education and 64.3% in the post-education survey. After education, knowledge level was improved (mean score from 4.3±2.11 to 6.7±1.96 points, modal value from 3 to 8 points) and positive changes were observed in almost all questions on attitudes. In the post-education survey, more students felt that they could do causality assessment (from 13% to 80.5%), could report adverse events to the agency in charge (from 7.4% to 96.2%), and expressed their strong willingness to report adverse events in the future (from 77.8% to 88.9%) than in the pre-education survey. Conclusions: More schools of Korean medicine need to adopt pharmacovigilance training courses in their curriculum to foster future doctors of Korean medicine with pharmacovigilance capabilities. Such efforts will be the basis for achieving an evidence-based, safe use of herbal medicine.

  • High-caffeine energy drink consumption has been increasing in young adults, frequently causing the most common symptoms such as tremor, insomnia, anxiety, and nervousness and rarely leading to serious adverse effects like seizure, acute mania, and stroke due to caffeine overdose. There have been little current studies regarding analysis of high-caffeine energy drink consumption and its adverse effects in Korea. This study was to examine high-caffeine consumption patterns, associated factors, and adverse effects based on responses from 231 college students in a University through survey. About 88.3% (n=204) of total respondents reported that they had energy drinks. College students mostly consumed energy drinks to keep awake (46%) when studying and to recover fatigue (27%). Approximately 44% respondents mainly reported palpitation (73.9%) and insomnia (72.8%) regarding adverse effect questionnaire. Current reports on the risk of recreational use, co-ingestion of alcohol and energy drink as well as energy drink consumption among children and adolescents are increasing, requiring further long-term research and awareness of these issues.
