This study explored the process of the professionalization of Korean Oriental medicine in Je-Han Medical Center. Je-Han Medical Center has fulfilled the requisites of the professionalization. The process of professionalization of Je-Han Medical Center is different from the process of professionalization of Western medical profession. Firstly, the Korean Oriental medical doctors of Je-Han Medical Center had been educated the standardized Korean Oriental medical knowledges. But the medical practices of them were not fully standardized. Secondly, the Korean Oriental medical doctors of Je-Han Medical Center have occupied the exclusive rights in the areas of Korean Oriental medicine. But there still exists the restriction of the range of license. Thirdly, the Korean Oriental medical doctors of Je-Han Medical Center had pride as a Korean Oriental medical doctor. They had the ideology as the national medical doctors. But the patients' use of Korean Oriental medicine were based on the practical reasons, not based on the ideological reasons. Fourthly, the inner hierarchy of Je-Han Medical Center was very strict. But the hierarchical and authoritarian relations between medical doctors and patients were very weak. Like this, we can find the unique process of professionalization of Korean Oriental medicine in Je-Han Medical Center. These findings can contribute to the extend the horizon of the sociology of profession.

Fat embolism syndrome is a rare, but serious condition that occurs in patients with fractures of the long bones or who undergo orthopedic surgery. The main clinical features of fat embolism syndrome are an altered mental status, hypoxia, and petechial rash. Cerebral fat embolism is the most severe manifestation of fat embolism syndrome because it can lead to an altered mental status. The diagnosis of cerebral fat embolism is clinical, but brain magnetic resonance image (MRI) is helpful. There is usually an interval until symptoms, such as an altered mental status, develop after trauma. We report a case of cerebral fat embolism in which the patient's mental status deteriorated several hours after trauma and the initial findings were negative on diffusion-weighted MRI.

Resistance to hypomethylating agents (HMAs) in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) is a concerning problem. Polo-like kinase 1 (PLK1) is a key cell cycle modulator and is known to be associated with an activation of the PI3K pathway, which is related to the stabilization of DNA methyltransferase 1 (DNMT1), a target of HMAs. We investigated the effects of volasertib on HMA-resistant cell lines (MOLM/AZA-1 and MOLM/DEC-5) derived from MOLM-13, and bone marrow (BM) samples obtained from patients with MDS (BM blasts >5%) or AML evolved from MDS (MDS/AML). Volasertib effectively inhibited the proliferation of HMA-resistant cells with suppression of DNMTs and PI3K/AKT/mTOR and ERK pathways. Volasertib also showed significant inhibitory effects against primary BM cells from patients with MDS or MDS/AML, and the effects of volasertib inversely correlated with DNMT3B expression. The DNMT3B-overexpressed AML cells showed primary resistance to volasertib treatment. Our data suggest that volasertib has a potential role in overcoming HMA resistance in patients with MDS and MDS/AML by suppressing the expression of DNMT3 enzymes and PI3K/AKT/mTOR and ERK pathways. We also found that DNMT3B overexpression might be associated with resistance to volasertib.

A survey was practiced to the medical doctors of Je-Han Medical Center and Taegu Catholic Medical Center from November to December 2004. The collected data was analysed by the SPSS10+. The analysis of frequency, cross table, the difference of mean was practiced. The focus of the analysis was to find the difference of attitudes between Korean Oriental medical doctors and Western medical doctors. The results of the analysis showed that Korean Oriental medical doctors are more active to the cooperated medical treatments than Western medical doctors. They also have more experience. And both of Korean Oriental medical doctors and Western medical doctors agree to the necessity of the cooperated medical treatments. But the preferred combination pattern of Korean Oriental medicine and Western medicine was different between two medical groups. Korean Oriental medical doctors prefer the one to one combination pattern. But Western medical doctors prefer to Western medicine centered combination pattern. This study has limitations in sampling prcesss and sample size. But considering that the study of the cooperated medical treatments is few, this study has considerable medical sociological meaning.

Background Although allogeneic hematopoietic cell transplantation (HCT) is the only curative treatment option for myelodysplastic syndrome (MDS), a substantial number of patients experience relapse. We reviewed the clinical outcomes of patients with MDS who relapsed after allogeneic HCT. Methods Thirty patients who experienced relapse or progression after allogeneic HCT for MDS between July 2000 and May 2016 were included in this retrospective analysis. Results The median time from HCT to relapse was 6.6 (range, 0.9-136.3) months. Donor lymphocyte infusions (DLIs) were administered to four patients: one achieved complete remission (CR) and survived disease free, while three did not respond to DLI and died. Hypomethylating agents were administered to seven patients: one who had stable disease continuously received decitabine, while six died without response to treatment. Six patients received AML-like intensive chemotherapy, and three achieved CR: two underwent second HCT and one DLI. One patient receiving second HCT survived without disease, but the other two relapsed and died. Three, four, and eight patients who did not respond to intensive chemotherapy, low-dose cytarabine, and best supportive care, respectively, died. One patient who underwent second HCT following cytogenetic relapse survived disease free. Median overall survival after relapse was 4.4 months, and relapse within 6 months after HCT was associated with shorter survival. Conclusion Outcomes of MDS patients relapsing after allogeneic HCT were disappointing. Some patients could be saved using DLI or second HCT.

춘천지역에서 포획한 한국 야생랫드(시궁쥐)에서 Capillaria hepatica에 자연감염된 예를 보고한다. Capillaria hepatica의 충란이 포획된 68마리의 랫드중 17마리에서 발견되었다. Capillaria에 감염된 랫드의 간장은 충란과 함께 림프구, 단핵구, 호산구의 침윤이 관찰되었고 심한 괴사소견을 보였다. 또한 섬유화, 출혈 hemosiderin의 침착이 뚜렷하게 관찰되었다. 최근 국내에서 자연에서 채집된 랫드의 Capillaria hepatica의 감염을 보고한 자료가 없는 것으로 미루어 Capillaria hepatica의 숙주감염을 파악하는 자료로 활용될 수 있을 것이다.

A scalp mass surgically excised from a 4-year-old Korean boy was identified as a tick through histological observations. In sections of the mass, characteristic features of a tick, including its gross contour, cuticular structures, well developed musculature and salivary glands, and the capitulum, were discovered. In particular, the capitulum is anteriorly protruded, which strongly suggests that the specimen be a hard tick of family Ixodidae. However, the pre-sent histological features were not enough to determine the genus and species of the tick, because information on sectional morphologies of different tick species is unavailable. This is a rare case of tick infestation on the scalp diagnosed in histological sections.

Objective : Rheumatoid arthritis (RA) is known to involve the cervical spine up to 86%. It often causes cervical instability like atlantoaxial subluxation (AAS), subaxial subluxation, and vertical subluxation (VS). In order to find the relation between RA and cord compression, we will evaluate the characteristics and risk factors of basilar invagination (BI) and cervicomedullary junction (CMJ) compression. Methods : From January 2007 to May 2015, 12667 patients administrated to Hanyang University Medical Center. Four thousand three hundred eighty-six patients took cervical X-ray and 250 patients took cervical computed tomography or magnetic resonance imaging. Radiologic parameters, medication records were obtained from 242 patients. Multivariate logistic regression analysis was performed with correlation of CMJ compression, basin-dental interval (BDI), basin-posterior axial line interval (BAI), pannus formation, BI, and AAS. Results : In the point of CMJ compression, atlantodental interval (ADI), posterior-atlantodental interval, BAI, AAS, and BI are relatively highly correlated. Patients with BI have 82 times strong possibility of radiologic confirmed CMJ compression, while AAS has 6-fold and pannus formation has the 3-fold possibility. Compared to the low incidence of BI, AAS and pannus formation have more proportion in CMJ compression. Furthermore, wrist joint erosion was correlated with VS and AAS. Conclusion : BI has a very strong possibility of CMJ compression, while AAS and pannus formation have a high proportion in CMJ compression. Hence bilateral wrist joint erosion can be used as an indicator for the timing of screening test for cervical involvement. We suggest the early recommendation of cervical spine examination for the diagnosis of cervical involvement in order to prevent morbidity and mortality.
