  • The aim of this systematic review was to collect evidence on the following 10 technical aspects of glenoid baseplate fixation in reverse total shoulder arthroplasty (rTSA): screw insertion angles; screw orientation; screw quantity; screw length; screw type; baseplate tilt; baseplate position; baseplate version and rotation; baseplate design; and anatomical safe zones. Five literature libraries were searched for eligible clinical, cadaver, biomechanical, virtual planning, and finite element analysis studies. Studies including patients >16 years old in which at least one of the ten abovementioned technical aspects was assessed were suitable for analysis. We excluded studies of patients with: glenoid bone loss; bony increased offset-reversed shoulder arthroplasty; rTSA with bone grafts; and augmented baseplates. Quality assessment was performed for each included study. Sixty-two studies were included, of which 41 were experimental studies (13 cadaver, 10 virtual planning, 11 biomechanical, and 7 finite element studies) and 21 were clinical studies (12 retrospective cohorts and 9 case-control studies). Overall, the quality of included studies was moderate or high. The majority of studies agreed upon the use of a divergent screw fixation pattern, fixation with four screws (to reduce micromotions), and inferior positioning in neutral or anteversion. A general consensus was not reached on the other technical aspects. Most surgical aspects of baseplate fixation can be decided without affecting fixation strength. There is not a single strategy that provides the best outcome. Therefore, guidelines should cover multiple surgical options that can achieve adequate baseplate fixation.

  • Objectives: This retrospective observational study aimed to investigate the efficacy and safety of Cheongpebaedok-tang, a traditional Korean herbal medicine, provided via telemedicine to patients with asymptomatic to mild COVID-19 in Korea. Methods: From February to April 2020, a retrospective analysis investigated COVID-19 patients treated via Korean telemedicine. The study involved asymptomatic to mild cases receiving Cheongpebaedok-tang more than three times, along with continuous Korean medicine care in convalescence. Diagnoses and treatment adhered to the telemedicine guidelines of the Association of Korean Medicine, with varied Cheongpebaedok-tang prescriptions based on symptom severity. Symptom evaluation involved a detailed assessment using a 15-item tool at initial and final sessions. Results: The study included 27 patients, with a mean age of 48.7 ± 2.3 years (mean ± standard error). Patients began self-administering oral Cheongpebaedok-tang for an average of 19.4 ± 1.8 days after the date of COVID-19 diagnosis confirmation and continued the medication for 15.8 ± 1.2 days. The reported side effects of the Cheongpebaedok-tang included palpitations (11.1%), insomnia (7.4%), dizziness (3.7%), and diarrhea (3.7%). All side effects disappeared after adjusting the prescription according to standard treatment guidelines. The occurrence of all COVID-19-related adverse symptoms, except fatigue and myalgia, decreased. Fatigue was the most common chronic symptom persisting after 6 months (51.9%), followed by ocular symptoms (37.0%) and sore throat (22.2%). Conclusions: This study implies Cheongpebaedok-tang may offer a potentially safe, symptom-alleviating approach for managing mild COVID-19 cases via telemedicine, although further comprehensive research is warranted.

  • Purpose: The purpose of this study was to examine the research characteristics and the trend of the Journal of the Korean Society of Clinical Toxicology by bibliometric analysis. Methods: This study was a retrospective quantitative literature review of the publications. We collected data from the internet homepage of the Korean Society of Clinical Toxicology. Among 228 publications, a total of 225 articles were included in this analysis. The data were analyzed from different perspectives, including article types, study design, number of authors, type of toxic material, and the top five ranking prolific authors and the affiliated organization were identified. Results: A total of 225 articles were analyzed; 98(43.6%) were original articles, 115(51.1%) were case reports, and 12(5.3%) were reviews. Among the original articles, nine were prospective studies and 89 were retrospective studies, which were assorted according to study design; there were two(2.0%) cross sectional studies, 93(94.9%) cohort studies, and three(3.1%) etc. The median number of authors per article was five and the top five ranking authors and affiliated organizations published 31.1% and 32.8% of total articles, respectively. The most abundant topic was pesticides, followed by natural poisons and poisons encountered in the work place. Conclusion: Since its foundation, the Journal of the Korean Society of Clinical Toxicology has published 19 issues and 228 articles and has played a key role in development of toxicology research in Korea. However, low ratio of original articles and a decrease in the number of recent articles indicates that greater effort is needed in clinical research. In addition, further interest of many experts and various institutions is necessary.

  • Open and closed rhinoplasty are two main approaches to perform nasal modifications. According to current literature, there is no current consensus among plastic surgeons and otolaryngologists on which technique is preferred in terms of aesthetic result, complications, and patient satisfaction. This study uses published research to determine whether open or closed rhinoplasty leads to superior patient outcomes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews were followed and a literature search was conducted in four databases based on our search strategy. Articles were then imported into COVIDENCE where they underwent primary screening and full-text review. Twenty articles were selected in this study after 243 articles were screened. There were 4 case series, 12 retrospective cohort studies, 1 prospective cohort study, 1 case-control, and 2 outcomes research. There were three cosmetic studies, eight functional studies, and nine studies that included both cosmetic and functional components. Sixteen studies utilized both open and closed rhinoplasty and four utilized open rhinoplasty. Both techniques demonstrated high patient and provider satisfaction and no advantage was found between techniques. Based on available studies, we cannot conclude if there is a preference between open or closed rhinoplasty in terms of which technique leads to better patient outcomes. Several studies determined that open rhinoplasty and closed rhinoplasty leads to comparative patient satisfaction. To make outcome reporting more reliable and uniform among studies, authors should look to utilize the Nasal Obstruction and Septoplasty Effectiveness scale and the Rhinoplasty Outcome Evaluation.

  • Middle East respiratory syndrome - coronavirus infection has posed substantial threat to public health with extremely high mortality rate in 2015. Although there are no approved novel medications for coronavirus, several antiviral agents such as ribavirin and interferon have been tried to MERS patients according to the in-vitro inhibitory effect, therapeutic effect on the animal model and experience from the severe acute respiratory syndrome - coronavirus infection. The aim of this study is to evaluate the clinical evidence of the antiviral treatment for MERS-CoV infection. After systematically searching the medical literature databases, I found five studies described the clinical efficacy of antiviral treatment on MERS patients. All of them were about the combination therapy of ribavirin and interferon (IFN). Two of them were retrospective cohort studies with quality of evidence (QOE) II and the others were observational study and case reports with QOE III. As a result of critical appraisal, it is concluded that none of those studies represented confirmatory clinical evidence of the efficacy of ribavirin and interferon combination therapy on MERS patients. Although Omrani et al. represented that ribavirin and IFN treatment had significantly improved survival at 14 days, it was not enough time to conclude the effect.

  • Purpose: This study was performed to evaluate the prevalence, distribution, and radiological features (as per the Shear classification) of dentigerous cysts in a Lebanese sample. Materials and Methods: It was an epidemiological, cross-sectional, 5-year retrospective study of 137 dentigerous cysts treated at Lebanese Army Dental Departments. The collected data comprised demographic and radiological information corresponding to patients from July 2015 to July 2020. Syndromic cases were excluded. Demographic data and the radiological features of cases were studied and analyzed. Results: Dentigerous cysts were treated in 109 patients (58.7% males and 41.3% females; mean age: 28.3±16.3 years) out of 6,013 patients(52% males and 48% females), with a prevalence of 1.8%. Dentigerous cysts were more commonly found in patients in their second and third decades of life than in older age groups. Of the 109 patients, 22.9% had multiple dentigerous cysts. Of the 137 cysts, 71.5% were mandibular. The most prevalent anatomical location was the posterior mandible, followed by the posterior maxilla. The most commonly involved tooth was the mandibular third molar. Regarding radiological types, the central type was the most common (60.6%), followed by the lateral type (29.2%), and the circumferential type (10.2%). Conclusion: The results of this study were similar to studies of other populations in terms of distribution and features. Multiple non-syndromic dentigerous cysts were more common than reported in other studies, which warrants further clinical studies to reveal previously undetected factors.

  • This article reviewed & analyzed 33 studies of the Health Belief Model applied to korean chronic ill patients which were published from 1975 to 1990. The findings of analysis are as follows. The subjects of researchs are patients with various chronic illness including Pulmonary Tb., DM., Hemodialysis & Kindney Transplantation, Hypertension, etc. The type of research is retrospective survey in all studies. The measurement of health' belief in all studies & sick role behavior in most studies have relied on self report. The analysis of the relationship between health belief and sick role behavior was done using correlation coefficient in most studies. To analyze empirical support for the relatiohship between health belief and sick role behavior, Significance ratio was computed. This ratio is value wherein the number of statistically significant findings with relationship in the expected direction for an HBM dimension are divided by total number of studies which reported significance levels for that dimension. Examination of this ratio across the 33 studies reveals susceptibility(30.3%), severity(34.4%), benifit(65.6%), barrier(50%). The following suggestions are based on the above findings and literature review. 1. It is necessary to develop the reliable, valid and standadized instrument for measurement of health beliefs. 2. In the further 'measurement of perceived susceptibility of the chronic ill patients, It is considering that the perceived susceptibility and perceived severity are measured together or the measurement of perceived, susceptibility is eliminated. 3. Relationship between perceived severity and sick role behavior is suggested to be analized using ANOV A, $x^2$ square instead of correlation coefficient. 4. Sick role behaviors should be measured by both self report and objective measurement. 5. Prospective, longitudinal survey should be needed. 6. Other factors influencing sick role behaviors of chronic ill patients should be investigated further.

  • Purpose: This study was conducted to evaluate the clinical efficacy of pharmacologic treatment of amatoxin poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, KoreaMed, KISS and KMBASE. Studies relevant to human use of pharmacologic therapy including silymarin, penicillin and N-acetylcysteine (NAC) for amanita poisoning were included. Case reports, letters, editorials and papers with insufficient information were excluded. Comparison of clinical outcomes (especially mortality and liver transplantation rate) in each study was analyzed. Results: The final analysis included 13 retrospective studies. None of these studies showed direct comparisons of individual agents. Among 12 studies comparing silymarin vs penicillin, eight showed clinical superiority of silymarin. Among eight studies comparing silymarin with NAC, six showed clinical superiority of silymarin. Among seven studies of NAC vs penicillin, five showed clinical superiority of NAC. Conclusion: This systematic review suggested that clinical superiority of various pharmacological agents used to treat amatoxin poisoning is debatable. Nevertheless, the available evidence suggests it is reasonable to consider combinations of multiple agents for patients with amanita poisoning. Further studies are required to establish a treatment regimen for amanita poisoning.
