1.Arthroscopy Assisted 2 Cannulated Screw Fixation for Transverse Glenoid Fracture: A Case Report.
Clinics in Shoulder and Elbow 2016;19(2):105-109
Arthroscopy is recognized as an important adjunct in treatment of intra-articular fractures. The author reports on successful treatment of a displaced transverse glenoid cavity fracture, reduced and fixed with arthroscopic assist, using two cannulated screws perpendicular to the fracture surface, in a patient with frail chest. One screw passed through the Neviaser portal, and the other screw passed through the base of the coracoid process. Arthroscopy assisted reduction and 2 cannulated screw fixation through the Neviaser portal and coracoid base appears to be a good method for treatment of transverse glenoid fractures.

2.Bilobate Anterior Epidural Extension of Vertebral Lesion: MRI Features.
Journal of the Korean Radiological Society 1994;31(5):955-959
PURPOSE: To determine the value of bilobate anterior epidrual extension(AEE) on MRI in differential diagnosis of tuberculous spondylitis, pyogenic spondylitis and malignant tumor. MATERIALS AND METHODS: SE TI-,T2- and Gd-DTPA enhanced Tl-weighted, sagittal and axial MR images of 39 patients(40 vertebral lesions), including 16 tuberculous spondylitis, 7 pyogenic spondylitis(8 lesions, consisting of 2 separate lesion of 1 patient), and 16 malignant vertebral tumors(15 metastases,1 lymphoma) with an AEE were reviewed. The frequency of bilobate AEE shown as double-convexity in the anterior epidural space on axial scans was evaluated in the above vertebral diseases. RESULTS: The bilobate AEE on the axial scans was seen in 12 out of the 16 tuberculous spondytitis(75%) and 1 out of 8 pyogenic spondylitis(13%), and 10 out of the 16 malignant tumor including 15 metastasis and 1 lymphoma(63%). CONCLUSION: The bilobate' ^EE of vertebral lesions is suggestive of tuberculous spondylitis or malignant tumor rather than pyogenic spondylitis. This pattern seems to be related with the preservation of the structures, including midline septurn, F~LL(Posterior longitudinal ligament), lateral membrane and fibrous membrane, limiting and surrounding the extension of the tuberculous spondylitis and malignant tumor, and with the early penetration or disruption of PLL, midline septurn, lateral & fibrous membranes in the pyogenic spondylitis.

Journal of the Korean Pediatric Society 2000;43(6):856-860
We examined a male infant with transient increase in alkaline phosphatase(ALP) activity. The 25-month-old infant was admitted to a local hospital because of pneumonia of unknown etiology. Initial laboratory investigation revealed a serum ALP of 11,260U/L, which was comparable to that of bone isoenzyme on the electrophoresis pattern, There was no evidence of hepatitis, skeletal or intestinal diseases. The hyperphosphatasemia disappeared 3 months later. We report a case of transient hyperphosphatasemia diagnosed inci- dentally in the course of management of pneumonia.

Twenty-five paraffin-embedded tumor tissues were analyzed for detection of HPV 16 and 18 in cervical adenocarcinoma by polymerase chain reaction with type specific primers and by non-radioactive Southern blot hybridization for confirmation . The suitability of paraffin-embedded tissue as PCR material was confirmed by successful amplification of 100% of cervical specimens with human -globin specific primer. Eighty four percent of the cervical adenocarcinoma tissues were positive for HPV 16 and/or 18. HPV 16 positive rate was 68%, HPV 18 was 60%. The double infection with HPV 16 and 18 was found in 44%. Three cases of the negative specimen in PCR for each type of HPV DNA 16 and 18 were positive in Southern blot hybridization. The total positive rate was 92% for HPV 16 and/or HPV 18, HPV 16 positive rate was 80%. HPV 18 was 72%. The double infection with HPV 16 and 18 was 60%. These results suggest that the pattern of HPV types 16 and 18 is closely associated with carcinogenesis of cervical cancers. HPV type 18 appears to be preferentially related to cervical adenocarcinoma and the poor prognosis of these patients. Therefore, determination of HPV DNA type in cervical carcinoma patients is important in treatment and prognosis.

Calcareous corpuscles are a characteristic structure found in larval and adult stage cestodes. These corpuscles are known to contain several protein components and to possess protein-binding activity. However, the proteins bound to calcareous corpuscles in situ have not been studied. The present study was undertaken to identify the proteins on calcareous corpuscles. Calcareous corpuscles were purified from the plerocercoids (= spargana) of Spirometra erinacei, and serially dissolved using 0.1 M sulfamic acid solution. Collected supernatants were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and silver staining. The results showed that only the fraction remaining after the 19th dissolved fraction contained proteins. A total of 20 protein molecules were detected in gel, with major bands at 56, 53, 46, 40, 35, 29, 28, 24.5, 21, 19, 16, 13, 10 and 8 kDa. In particular, the proteins corresponding to the 21 and 16 kDa bands were most abundant. Our results demonstrated for the first time the protein contents of the calcareous corpuscles of spargana. Further studies on the functions of these proteins are required.

6.Minimally Invasive Repair Technique of Achilles Tendon Using Sponge Forceps: A Technical Report.
Journal of Korean Foot and Ankle Society 2016;20(2):88-91
Various minimally invasive repair techniques have been performed for acute Achilles tendon rupture. Despite this, it is difficult to use these techniques in common practice because of the necessity of special instruments. We propose a novel minimal invasive technique using sponge holding forceps, which are commonly used in the operating room for the acute Achilles tendon rupture.

Cryptosporidium parvum oocysts were isolated from a child suffering from acute gastroenteritis and successfully passaged in a calf and mice (designated hereafter SNU-H1) in the Republic of Korea; its molecular genotype has been analyzed. The GAG microsatellite region was amplified by a polymerase chain reaction (PCR), with a 238 base pair product, which is commonly displayed in C. parvum. The isolate was shown to be a mixture of the genotypes 1 (anthroponotic) and 2 (zoonotic). To study its infectivity in animals, 2 calves and 3 strains of mice were infected with the SNU-H1; in these animals, the propagation of both genotypes was successful. In immunosuppressed (ImSP) BALB/c and C57BL/6 mice the number of oocysts decreased after day 10 post-infection (PI) ; but in ImSP ICR mice, they remained constant until day 27 PI. The results show that both the C. parvum genotypes 1 and 2 can be propagated in calves and ImSP mice.

Korean Journal of Medical Education 2018;30(2):153-159
PURPOSE: Nonverbal communication (NVC) is important in the patient-physician relationship, but the effect of NVC education is not well kown. In this study, we try to identify if students' NVC abilities are improved through communication training. METHODS: First-year medical students conducted medical interviews, which were performed with standardized patients (SPs) before and after communication skill education, and recorded in video. Fifty-one students were enrolled for this study. Two researchers used the NVC checklist, which consists of 12 nonverbal behaviors, to analyze and compare the students' nonverbal expressions in the interviews recorded before and after the education. RESULTS: After the students participated in communication training, open body position and adequate facial expression were increased while unnecessary silence, un-purposive movements, and giggling were decreased. These results can be interpreted as positive effects of the education. However, hand gesture was increased as a negative effect of the education. The total NVC score of the 12 nonverbal behaviors in the NVC checklist improved significantly, rising from 8.56 to 10.03. CONCLUSION: Communication skill education using SPs can improve nonverbal behaviors of medical students, especially facial expression, un-purposive movement, body position, unnecessary silence, and giggle, but not hand gesture. Further research is needed on a variety of teaching methods to improve NVCs.

Korean Journal of Medical Education 2018;30(3):199-208
PURPOSE: Nonverbal communication (NVC) may be a crucial factor affecting effective communication between patients and medical students during the objective structured clinical examination (OSCE), but it has not been intensively studied. We examined NVC and its correlation with patient-physician interaction (PPI) in the OSCE. METHODS: A total of 68 video recordings of routine check-up OSCEs were included. A checklist for NVC was developed that included seven nonverbal factors in a mute state (NVM) and four nonverbal factors in speech (NVS), and one point was assigned to each factor. The scores for history taking, PPI, NVM, and NVS were compared, and correlations of each score were evaluated. RESULTS: Students with adequate facial expressions, accorded speech rate and voice volume, adequately matched voice tone, and few or no moments of unnecessary silence showed better PPI scores. The PPI score was correlated with history taking and the NVS score, but not the NVM score. CONCLUSION: Our results suggest that NVS may be more influential to PPI during OSCEs than NVM. Communication teachers should help students to be better prepared to use both NVS and NVM properly.

Korean Journal of Orthodontics 1997;27(4):607-621
GRP was known as the modulator of pain transmission in central nervous system and local effector to peripheral tissue causing vasodilation, increased blood flow, modulation of immune system, stimulation of endothelial cell proliferation, and stimulation of bone formation. Numerous study, therefore, were done to elucidate involvement of CGRP to tooth movement. To investgate the response of CGRP immunoreactive nerve cells according to cell size in trigemeinal ganglion during tooth movement, immunohistochemical study was performed using rat. Experimental rats(9 weeks old, 210 gm) were divided as six groups(normal(n=6), 3 hours group(n=5), 12 hour group(n=4), 1 day group(n=5), 3 day group(n=5), 7 day group(n=5)), and were applied orthodontic force (approximately 30 gm) to upper right maxillary molar. After frozen sections of trigeminal ganglions were immunostained using rabbit antisera, the changes of CGRP immunoreactive cells in regard to cell size distribution(small cell(up to 20 microgramm), medium cell(20-35 microgramm), large cell(above 35 microgramm)) were observed. The results were as follows 1. The percentage of CGRP immunoreactive cells to all nerve cells in trigeminal ganglion was 33.0% in normal control group, was decreased to 24.5% in 1 day group, and was increased to 41.8% in 7 day group. 2. The percentage of small, medium, and large cells expressing CGRP immunoreactivity in normal trigeminal ganglion to all CGRP immunoreactive cells were 51.3%, 44.0%, 4.7%, respectively. 3. The percentage of small cells with CGRP immunoreactivity to all CGRP immunopositive cells was increased in 3 hour and 12 hour groups. 4. The percentage of medium cells with CGRP immunoreactivity was increased in 3 day and 7 day groups. 5. The percentage of large cells with CGRP immunoreactivity was increased in 7 day group. Conclusively, the small cells with CGRP immunoreactivity in trigeminal ganglion respond to orthodontic force during initial phase of tooth movement, and later the medium and large with CGRP immunoreactivity respond.
