Purpose: Alport syndrome (AS) is one of the most common inherited renal diseases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term deterioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies.

Objectives : The purpose of this study is to evaluate the clinical aspects of patients with Soyangin vitiligo. Methods : This clinical investigation was made with 148 Soyangin Vitiligo patients who visited Haneulmaeum Oriental Medicine Clinic (Incheon) from July 1st 2007 to June 30th 2017. Results & Conclusions : 1. There were 73 males(49.3%) and 75 females(50.7%). 2. The Mean age at the first visit was 36.1 years(male: 36.4, female: 35.8). 3. The Mean age of onset was 27.9 years(male: 28.6, female: 27.4). 4. The mean duration of the disease was 8.0 years(male: 7.8, female: 8.3). 5. Of the 148 patients, 41(27.7%) had the symmetric lesions and 107(72.3%) had the asymmetric vitiligo lesions. Of the patients with asymmetric vitiligo lesions, 46(31.1%) had the localized lesions and 26(17.6%) had the segmental lesions and 35(24.3%) had the multiple lesions. 6. The most common site of initial involvement of the vitiligo was the face (39.2%). 7. The most common site of the vitiligo lesions was the face(49.3%). 8. Familial history was obtained in 12 patients(8.1%). 9. There was no known precipitating factor in most cases(89.4%). 10. Thyroid disease was the most common associated disease. 11. The progression of vitiligo was present in 92 patients(62.2%).
Background: The objective of the present study was to specifically divide the various work performed by dental hygienists in clinical practice for legal amendments regarding problems associated with conflict between job roles and illegal delegation to establish key basic data for legislation and policy utilization for realization of legal scope of dental hygienists. Methods: The study used work reports drafted based on research methods in the "Second Job Analysis Report on Dental Hygienists" researched by the Korean Health Personnel Licensing Examination Institute in 2012 and "Opinions of Dentists on Actual and Legal Work of Dental Hygienists," a report published by the Korean Dental Hygienists Association. Of these, the study focused on conservation dentistry, pediatric dentistry, prosthodontics, oral and maxillofacial surgery, and dental implant treatment, which make up some of the fields covered by dental hygiene practice, to investigate and analyzed work performed by clinical experience. Results: Analysis of work actually performed in dental practice showed that for work related to 33 items presented in the study methods, the participants responded that they are currently performing such work or are likely to perform such work in the future, although there were differences by year. Investigation by type of workplace showed that dental hygienists working in university hospitals could perform the work presented if they had ≥5 years of dental hygienist experience, whereas dental hygienists working in dental clinics or hospitals could perform simple duties in their first year and performed more diverse duties with greater degree of difficulty after their second to fourth year. Conclusion: The reality that medical assistance during surgical operations and various procedures that is still being performed is no longer legally protected directly contradicts the needs in dental practice, and thus, there is the need to amend laws that are realistic by clearly recognizing the work of dental hygienists.
Purpose: The aim of this study was to investigate the effect of (1) the size of the bony access window and (2) collagen membrane coverage over the window in sinus floor elevation in a rabbit sinus model. Methods: Small bony access windows (SW; ø 2.8 mm) were made in 6 rabbits and large windows (LW; ø 6 mm) in 6 other rabbits. Both sinuses in each rabbit were allocated to groups with or without coverage of a collagen membrane (CM) on the window, resulting in 4 groups: SW, LW, SW+CM, and LW+CM. After 4 weeks of healing, micro-computed tomographic, histologic, and histomorphometric analyses were performed. Results: Bony healing in the window area was incomplete in all groups, but most bone graft particles were well confined in the augmented cavity. Histologically, the pattern of new bone formation was similar in all groups. Histomorphometrically, the percentage of newly formed bone was greater in the groups with CM than in the groups without CM, and in the groups with SW than in the groups with LW (12.92%±6.40% in the SW+CM group, 4.21%±7.73% in the SW group, 10.45%±4.81% in the LW+CM group, 11.77%±3.83% in the LW group). The above differences were not statistically significant (P>0.05). Conclusions: The combination of a small bony access window and the use of a collagen membrane over the window favored new bone formation compared to other groups, but this result should be further investigated due to the limitations of the present animal model.

Elbow traumas represent a relatively common condition in clinical practice. However, there is a lack of evidence regarding the most accurate tests for screening these potentially serious conditions and excluding elbow fractures. The purpose of this investigation was to analyze the literature concerning the diagnostic accuracy of clinical tests for the detection or exclusion of suspected elbow fractures. A systematic review was performed using the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines. Literature databases including PubMed, Cumulative Index to Nursing and Allied Health Literature, Diagnostic Test Accuracy, Cochrane Library, the Web of Science, and ScienceDirect were searched for diagnostic accuracy studies of subjects with suspected traumatic elbow fracture investigating clinical tests compared to imaging reference tests. The risk of bias in each study was assessed independently by two reviewers using the Quality Assessment of Diagnostic Accuracy Studies 2 checklist. Twelve studies (4,485 patients) were included. Three different types of index tests were extracted. In adults, these tests were very sensitive, with values up to 98.6% (95% confidence interval [CI], 95.0%-99.8%). The specificity was very variable, ranging from 24.0% (95% CI, 19.0%-30.0%) to 69.4% (95% CI, 57.3%-79.5%). The applicability of these tests was very high, while overall studies showed a medium risk of bias. Elbow full range of motion test, elbow extension test, and elbow extension and point tenderness test appear to be useful in the presence of a negative test to exclude fracture in a majority of cases. The specificity of all tests, however, does not allow us to draw useful conclusions because there was a great variability of results obtained.

Objectives: This study aimed to understand the current status of clinical practice patterns of Korean medicine in the treatment of degenerative arthritis of the hip and finger joints using web-based survey. Methods: An e-mail questionnaire survey was conducted with the Korean Medicine Doctor(K.M.D) registered in the Korean Medicine Association. The survey data were analyzed using Microsoft Excel. Results: Although the response rate of the survey was low, the characteristics of the respondents generally reflected the characteristics of the study population. A total of 35.2% of the respondents had heard of the guidelines; however, they did not use them for medical treatment. The reason as answered by 32.8% of the respondents was "not enough treatment time to check the manual and apply it." More than half (78.80%) answered that they were treating patients with both degenerative hip and finger arthritis; however, the average monthly number of first-time patients was ≤5. A total of 379 (60.9%) respondents answered that "acupuncture is very important," which was the only one that exceeded the majority compared to other treatments. As a result of the safety investigation, "Acupuncture, herbal medicine, cupping" were considered high in safety, while "Pharmacopuncture and Bee venom acupuncture" were considered low in safety. Conclusions: This survey helped to determine the current clinical practice patterns of Korean medicine treatments, further providing basic data for CPGs for degenerative arthritis of the hip and finger joints.

Bird species, particularly poultry and other bird types, including domestic pigeons, are susceptible to fowl pox, a contagious viral disease. The main goal of this study was to validate clinical avipoxvirus diagnoses using molecular analytical methods. The essential components of the investigation were the clinical signs, visible abnormalities, histological changes, and polymerase chain reaction analysis. Twenty out of 120 pigeons had clinical symptoms, which included yellowish crust or nodules near the feet, eyes, and beak. An erosive epidermal lesion and an epidermal acanthotic papular lesion with basal vacuolation were maculopapular evidence associated with significant epidermal hyperkeratosis, as confirmed by histological analysis. In addition, the results showed keratinocyte necrosis beneath the hyperkeratotic epidermal layer, together with superficial and deep dermal perivascular lymphocytic infiltration. In addition, the P4b core protein gene underwent phylogenetic analysis. The sequence analysis results indicated a high degree of similarity across the local strains, with just minor variations observed. Five sample sequences were selected and submitted to the NCBI database. These sequences were identified as OR187728, OR187729, OR187730, OR187731, and OR187732. All the various strains in this research may be classified under clade A of the chicken pox virus phylogenetic classification. This study presents the first description and characterization of pox virus infections in domestic pigeons inside the Basrah governorate.
The purpose of this study is to encourage the circulation of good quality of oriental medicine and to improve national welfare. Investigation for the induction of quality inscription system was conducted by mail and interview. The data were analyzed by SAS. The major results were as follows: The portion of subjects agree to necessity of quality inscription was 78.5%. In the question of side effect against quality inscription, the rate of negative was 67.7%. The responses answered that the necessity of quality inscription was not economical profit but authority of knowledge and improvement on health(37.8%), established market for herbal medicine(34.7%) and effect of clinical care(23.9%), respectively These results might be useful information for establishing of quality inscription system for herbal medicine.
Data exclusivity is one of the most important intellectual property rights of pharmaceuticals. During data exclusivity period, third parties are prohibited from relying on the data which the original company has submitted to regulatory authority for drug application. I investigated data exclusivity systems for pharmaceuticals in the US, EU, Canada and Korea. New chemical entities were usually given the longest periods of data exclusivity compared to drugs with new indication or new formulation, although the protection periods varied by country. For new drugs to be entitled to a data exclusivity, strict conditions should be met. Data exclusivity has also been provided as an incentive to promote clinical investigation and drug development for pediatric population or orphan diseases. In Korea, data exclusivity was adopted in 1995 as an additive provision to "drug re-examination" which is to investigate post-marketing safety information of new drugs. It was introduced with few discussion on the purposes or effects of data exclusivity on pharmaceutical industry and pharmaceutical market in this country. I found that Korea's data exclusivity system falls short of considerations on valuing innovation of pharmaceutical research. It is necessary to improve data exclusivity system in order to promote innovative pharmaceutical development and to balance intellectual property rights protection and access to drugs in this country.
The purpose of the present study was to evaluate the bioequivalence of two torasemide tablets, Torem tablet (Roche Korea Co., Ltd., Korea, reference drug) and Boryung Torsemide tablet (Boryung Pharmaceutical Co., Ltd., Korea, test drug), according to the guidelines of Korea Food and Drug Administration (KFDA). After adding an internal standard (furosemide) to human serum, serum samples were extracted using 5 mL of ethyl acetate. Compounds were analyzed by reverse-phase HPLC method with UV detection. This method showed linear response over the concentration range of 0.05 ug/mL with correlation coefficient of 0.999. The lower limit of quantitation using 0.5 mL of serum was 0.05 ug/mL which was sensitive enough for pharmacokinetic studies. Twenty-eight healthy male Korean volunteers received each medicine at the torasemide dose of 20 mg in a $2{\times}2$ crossover study. There was a one-week washout period between the doses. Serum concentrations of torasemide were monitored by an HPLC-UV for over a period of 12 hr after the administration. $AUC_{t}$(the area under the serum concentration-time curve from time zero to 12 hr) was calculated by the linear trapezoidal rule method. $C_{max}$ (maximum serum drug concentration) and $T_{max}$ (time to reach $C_{max}$) were compiled from the serum concentration-time data. Analysis of variance was carried out using logarithmically transformed $AUC_{t}$ and $C_{max}$. No significant sequence effect was found for all of the bioavailability parameters indicating that the crossover design was properly performed. The 90% confidence intervals of the $AUC_{t}$ ratio and the $C_{max}$ ratio for Boryung Torsemide/Torem were log 0.97-10g 1.03 and log 0.93log 1.12, respectively. These values were within the acceptable bioequivalence intervals of log 0.80-log 1.25. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating Boryung Torsemide tablet and Torem tablet are bioequivalent.
