Objectives : Although integrative Korean medical treatments have been suggested to be effective for treating Bell's palsy, the effect of Korean medical treatment according to when treatment was started is unknown in the clinical field. Therefore, this study was conducted to determine the results of treating Bell's palsy according to different starting points of integrative Korean medical treatments. Methods : We screened patients who visited the Facial Palsy Center at Kyung Hee University Hospital for Korean and Western combined medical treatment from March 2011 to February 2016. A total of 821 out of 2086 patients were studied, including their basic characteristics and results of an electromyography. Patients who started Korean medical treatment within 3 days of onset were placed in group A, within 9 days of onset in group B, and patients who started treatment after 10 days of onset were placed in group C. We tried to compare the level of facial nerve damage by electromyography between groups. Results : The patients in group C had the highest axonal loss rates in all branches(frontal, oculi, nasal, oris). The post hoc analyses revealed the difference of axonal loss rates between group A and B was not statistically significant. Only group C showed statistically higher axonal loss rates in all branches. Conclusion : The study results showed that the patients who had delayed Korean medical treatments had a higher level of facial nerve damage by electromyography. According to the results of this study, early application of integrative Korean medical treatment is suggested.

Purpose: This study attempts to compare the stability of hydroxy-apatite coating implant with that of sandblasted, large-grit and acid-etched surface implant at an early state of installation. Methods: 35 implants were installed in 18 patients, who had visited hospital for implant installation. The early stability at operation, 6 weeks and 12 weeks after operation using Osstell$^{TM}$ mentor (Integration Diagnostics, Savedalen, Sweden) and Periotest$^{(R)}$ (Siemens AG, Benssheim, Germany) were measured, and subsequently analyzed statistically. Results: OsstellTM mentor value of hydroxy-apatite coated implant (HAPTITE) was measured as $70.14{\pm}9.07$ at the stage of installation, $76.98{\pm}5.25$ at 6 weeks and $80.28{\pm}4.23$ at 12 weeks after installation. A statistically significant increase in measurement value was observed after 6 weeks and 12 weeks than when implants were placed. In case of IMPLANTIUM (DENTIUM Co. Ltd., Seoul, Korea), the measurement value was $74.68{\pm}7.42$ at installation, $79.03{\pm}4.39$ at 6 weeks and $80.59{\pm}3.59$ at 12 weeks after installation. In addition, a statistically significant increase in the value was observed when comparative analysis of the value at after installation and 12 weeks after installation was carried out. However, no significant difference between HAPTITE and IMPLANTIUM was observed. The average measurement value of periotest$^{(R)}$ was $-1.94{\pm}3.90$ at installation of HAPTITE, $-4.03{\pm}1.48$ at 6 weeks and $-5.00{\pm}1.71$ at 12 weeks after installation. Moreover, whilst comparing the value at after installation and 12 weeks after installation, statistically significant decrease in the value was observed. In case of IMPLANTIUM, the average measurement value was measured as $-4.25{\pm}1.76$ at installation, $-4.76{\pm}0.97$ at 6 weeks and $-5.18{\pm}0.91$ at 12 weeks after installation and no statistically significant difference was observed. Furthermore, no statistically significant difference was observed between HAPTITE and IMPLANTIUM. Conclusion: In this study, both the implants demonstrated favorable early stability at the time of measurement using Osstell$^{TM}$ mentor and Periotest$^{(R)}$. Moreover, based on the observed results, both HAPTITE and IMPLANTIUM are considered as potent to exhibit clinically stable and prognostic results.

Background: Line probe assay (LPA) is standard diagnostic tool to detect multidrug resistant tuberculosis. Non-interpretable (NI) results in LPA (complete missing or light wild-type 3 and 8 bands with no mutation band in rpoB gene region) poses a diagnostic challenge. Methods: Sputum samples obtained between October 2016 and July 2017 at the Intermediate Reference Laboratory, All India Institute of Medical Sciences Hospital, New Delhi, India were screened. Smear-positive and smear-negative culture-positive specimens were subjected to LPA Genotype MTBDRplus Ver 2.0. Smear-negative with culture-negative and culture contamination were excluded. LPA NI samples were subjected to phenotypic drug susceptibility testing (pDST) using MGIT-960 and sequencing. Results: A total of 1,614 sputum specimens were screened and 1,340 were included for the study (smear-positive [n=1,188] and smear-negative culture-positive [n=152]). LPA demonstrated 1,306 (97.5%) valid results with TUB (Mycobacterium tuberculosis) band, 24 (1.8%) NI, three (0.2%) valid results without TUB band, and seven (0.5%) invalid results. Among the NI results, 22 isolates (91.7%) were found to be rifampicin (RIF) resistant and two (8.3%) were RIF sensitive in the pDST. Sequencing revealed that rpoB mutations were noted in all 22 cases with RIF resistance, whereas the remaining two cases had wild-type strains. Of the 22 cases with rpoB mutations, the most frequent mutation was S531W (n=10, 45.5%), followed by S531F (n=6, 27.2%), L530P (n=2, 9.1%), A532V (n=2, 9.1%), and L533P (n=2, 9.1%). Conclusion: The present study showed that the results of the Genotype MTBDRplus assay were NI in a small proportion of isolates. pDST and rpoB sequencing were useful in elucidating the cause and clinical meaning of the NI results.

Objectives : We investigated the efficacy and safety of miniscalpel acupuncture (MA) treatment combined with non-steroidal anti-inflammatory drugs (NSAIDs) for chronic neck pain (CNP) in an assessor-blinded randomized controlled pilot trial to establish a basis for larger-scale randomized controlled studies on this subject. Methods : Participants (n=36) were recruited and randomly allocated to the MA group, NSAIDs and combined treatment group. The MA group received MA three times over three weeks. The NSAIDs group was administered orally with zaltoprofen 80mg t.i.d. over three weeks. The combined treatment group received MA and zaltoprofen in the same manner as MA and NSAIDs groups. The primary outcome was pain as assessed by a visual analogue scale (VAS) and the secondary outcomes were assessed using the Neck Disability index (NDI), EuroQol 5-dimension questionnaire (EQ-5D), and Patients' Global Impression of Change scale (PGIC). Assessments were made at week 0 (baseline), 1, 2, 3 (primary end point) during treatment and at week 7 (4 weeks after the end of treatment). Results : 35 participants completed the study. No serious adverse event occurred and blood test results were within normal limits. The improvement of VAS and NDI was significantly greater in combined and MA group than that in NSAIDs group (p<0.017). The combined group showed better outcomes in EQ-5D at visit 2 and 5, in PGIC at visit 4 than the NSAIDs group (p<0.017). No significant differences were found between combined and MA group. Conclusions : Our results suggest that both combined and MA group can be more effective in improving pain control than NSAIDs group. A large-scale clinical study is warranted to further clarify these findings.

의료기관에는 진단용 방사선 발생장치를 취급하는 방사선사, 의사, 치과의사, 치과위생사 등 방사선 관계 종사자가 있다. 그리고 간호사, 간호조무사 등 방사선진료를 보조하거나 방사선 검사실로 환자이송 등을 하는 업무 보조자들이 있다. 방사선 관계 종사자는「의료법」 등에 의해 방사선 피폭관리가 이루어지고 있으나 방사선 진료업무 보조자 등은 이에 대한 법적 근거가 없는 실정이다. 또한 진단용 방사선 피폭관리는 의료법령에 의해 규율되고 있고, 치료용 방사선과 핵의학검사에 의한 방사선 피폭관리는「원자력안전법」의 규율을 받고 있다. 이에 진단용 방사선에 의한 피폭관리를 개선하기 위하여「의료법」 상 진단용 방사선 피폭관리에 관한 규정과「원자력안전법」 상 관련 규정들을 비교·검토하여 보았다. 그 결과로 얻은 주요 내용은 다음과 같다. 첫째, 진단용 방사선에 의한 피폭관리 대상으로 방사선 관계 종사자 외에 방사선 피폭 우려가 있는 간호사, 간호조무사, 임상실습 학생 등을 포함시켜 입법적으로 해결할 필요가 있다. 둘째,「원자력안전법」에서처럼 진단용 방사선 관계 종사자가 임신이 확인된 경우에는 피폭선량 한도를 명문으로 규정해야 한다. 셋째,「진단용 방사선 발생장치의 안전관리에 관한 규칙」의 개인피폭선량계의 종류에 관한 규정을 현실에 맞게 개정할 필요가 있다. 넷째, 방사선 관계 종사자, 방사선작업종사자와 수시출입자에 대한 건강진단의 검사항목은 동일해야 할 것으로 보인다. 다섯째, 의료기관에서 진단용 방사선뿐만 아니라 치료용 방사선과 핵의학을 포함한 의료용 방사선 전체를 하나의 법체계에서 통일하여 규율하는 것이 필요하다고 본다.

Purpose: Artificial intelligence (AI) is poised to play a major role in medical diagnostics. Periodontal disease is one of the most common oral diseases. The early diagnosis of periodontal disease is essential for effective treatment and a favorable prognosis. This study aimed to assess the effectiveness of AI in diagnosing periodontal bone loss through radiographic analysis. Materials and Methods: A literature search involving 5 databases (PubMed, ScienceDirect, Scopus, Health and Medical Collection, Dentistry and Oral Sciences) was carried out. A specific combination of keywords was used to obtain the articles. The PRISMA guidelines were used to filter eligible articles. The study design, sample size, type of AI software, and the results of each eligible study were analyzed. The CASP diagnostic study checklist was used to evaluate the evidence strength score. Results: Seven articles were eligible for review according to the PRISMA guidelines. Out of the 7 eligible studies, 4 had strong CASP evidence strength scores (7-8/9). The remaining studies had intermediate CASP evidence strength scores (3.5-6.5/9). The highest area under the curve among the reported studies was 94%, the highest F1 score was 91%, and the highest specificity and sensitivity were 98.1% and 94%, respectively. Conclusion: AI-based detection of periodontal bone loss using radiographs is an efficient method. However, more clinical studies need to be conducted before this method is introduced into routine dental practice.
