It is known that aggressive treatment of chemotherapy, radiation and autogenous stem cell transplantation is effective for prevention of recurrence in the high-risk breast cancer patients. It was assumed that this procedure takes a longer time and decreases the quality of life more than the standard adjuvant chemotherapy. However, there are few studies comparing the quality of life of patients having bone marrow transplantation and adjuvant chemotherapy. Most of the studies were focused on the quality of life in one point of time, such as only during the early treatment stage, only overall quality of life rather than specific dimensions of the quality of life. The purposes of this study are 1) to identify the difference of the quality of life between two different treatment patterns, adjuvant chemotherapy and autogenous stem cell transplantation: 2) to identify the mostly affected dimension and the periods of time affected by the treatment patterns; and 3) to identify the trajectories of quality of life in each treatment pattern. This is a time series design that measures 4 different points of times. At the beginning of the study, 19 patients were placed in the chemotherapy group and 12 in the group of auto-peripheral blood stem cell transplantation. The inclusion criterion was the advanced disease stage of 3 or over with metastasis of more than 5 lymph nodes. The exclusion criteria were 1) anyone who has metastasis to other organ; 2) anyone who had psychological problems. Ferrell's Quality of Life Scale for Cancer Survivors 41 items on a 10 point scale was used. The QOL-CS includes 4 dimensions, which were labeled physical, psychological, social, and spiritual. The Cronbach‘s alpha of this scale was 0.89. Mann-Whitney U test and Friedman test were used to test each hypothesis. In comparison of the two groups, the quality of life of the bone marrow transplantation group dramatically increased at the 3rd and 6th month after transplantation, while the chemotherapy groups results stayed lower. The most affected dimension of the quality of life at the end of the treatment was the physical dimension. However, it and increased along with time, while the psychological dimension values remained low over the long-term period. Intensive nursing care is needed during the entire period of chemotherapy in all patients having chemotherapy, and is also required for right after cases of bone marrow transplantation.

Objective: The purpose of this study was to evaluate the diagnostic performance of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) for chronic empyema-associated malignancy (CEAM). Materials and Methods: We retrospectively reviewed the ¹⁸F-FDG PET/CT images of 33 patients with chronic empyema, and analyzed the following findings: 1) shape of the empyema cavity, 2) presence of fistula, 3) maximum standardized uptake value (SUV) of the empyema cavity, 4) uptake pattern of the empyema cavity, 5) presence of a protruding soft tissue mass within the empyema cavity, and 6) involvement of adjacent structures. Final diagnosis was determined based on histopathology or clinical follow-up for at least 6 months. The abovementioned findings were compared between the ¹⁸F-FDG PET/CT images of CEAM and chronic empyema. A receiver operating characteristic (ROC) analysis was also performed. Results: Six lesions were histopathologically proven as malignant; there were three cases of diffuse large B-cell lymphoma, two of squamous cell carcinoma, and one of poorly differentiated carcinoma. Maximum SUV within the empyema cavity (p < 0.001) presence of a protruding soft tissue mass (p = 0.002), and involvement of the adjacent structures (p < 0.001) were significantly different between the CEAM and chronic empyema images. The maximum SUV exhibited the highest diagnostic performance, with the highest specificity (96.3%, 26/27), positive predictive value (85.7%, 6/7), and accuracy (97.0%, 32/33) among all criteria. On ROC analysis, the area under the curve of maximum SUV was 0.994. Conclusion: ¹⁸F-FDG PET/CT can be useful for diagnosing CEAM in patients with chronic empyema. The maximum SUV within the empyema cavity is the most accurate ¹⁸F-FDG PET/CT diagnostic criterion for CEAM.

Purpose: The significance of neuroendocrine differentiation (NED) in gastric carcinoma (GC) is controversial, leading to ambiguous concepts in traditional classifications. This study aimed to determine the prognostic threshold of meaningful NED in GC and clarify its unclear features in existing classifications. Materials and Methods: Immunohistochemical staining for synaptophysin, chromogranin A, and neural cell adhesion molecule was performed for 945 GC specimens. Survival analysis was performed using the log-rank test and univariate/multivariate models with percentages of NED ($P_{NED}$) and demographic and clinicopathological parameters. Results: In total, 275 (29.1%) cases were immunoreactive to at least 1 neuroendocrine (NE) marker. GC-NED was more common in the upper third of the stomach. $P_{NED}$, and Borrmann's classification and tumor, lymph node, metastasis stages were independent prognostic factors. The cutoff $P_{NED}$ was 10%, beyond which patients had significantly worse outcomes, although the risk did not increase with higher $P_{NED}$. Tumors with ${\geq}10%$ NED tended to manifest as Borrmann type III lesion with mixed/diffuse morphology and poorer histological differentiation; the NE components in this population mainly grew in insulae/nests, which differed from the predominant growth pattern (glandular/acinar) in GC with <10% NED. Conclusions: GC with ${\geq}10%$ NED should be classified as a distinct subtype because of its worse prognosis, and more attention should be paid to the necessity of additional therapeutics for NE components.

Background: Community-acquired pneumonia (CAP) is an important cause of morbidity and mortality throughout the world in all age groups. Viral causes of CAP are less well characterized than bacterial causes. We analyzed the characteristics of hospitalized patients with CAP who had a viral pathogen detected by multiplex polymerase chain reaction (PCR). Methods: Multiplex real-time PCR was performed for respiratory viruses in samples collected from 520 adults who developed CAP at Chungnam National University Hospital. Clinical, laboratory, and radiological features at presentation as well as other epidemiological data were analyzed. Results: Of 520 patients with CAP, a viral pathogen was detected in 60 (11.5%), and influenza A was the most common. The virus detection rate in patients with CAP was highest in November. Two or more pathogens were detected in 13 (21.7%) patients. Seven patients had severe disease and were administered in the intensive care unit. Most patients (49/60, 81.7%) had comorbidities. However, nine (15%) patients had no comorbidities, and their age was <60 years. The ground glass opacity pattern was the most common radiological feature. Seven (11.7%) patients died from CAP. Conclusion: Viral pathogens are commonly detected in patients with CAP, and a respiratory virus may be associated with the severity and outcome of pneumonia. Careful attention should be paid to the viral etiology in adult patients with CAP.

The characteristics of Jin's ideas on clinic theory can be arranged as follows. 1. Jin emphasized warming and tonifying[溫補] in treatment and the part that shows this the best is the taking care of[調理] the Vital gate[命門], kidney, liver, and spleen. His ideas were based on his understanding of a human life's origin, and was influenced by Seolgi(薛己), Joheon-ga(趙獻可) and Janggaebin(張介賓)'s Vital gate and source Gi theory(元氣說) so scholastically, he has that in common with them but was later criticized by later doctors such as Oksamjon(玉三尊) as an 'literary doctor(文字醫)' who followed the ideas of "Uigwan(醫貫)". 2. The warming and tonifying school[溫補學派], who were influenced by Taoism, said in their theory of disease outbreak[發病學說] that since one must not hurt one's Yin essence and Yang fire [陰精陽火] there is more deficiency than excess, so that was why they used tonifying methods. Jin was also like them and this point of view is universal in internal medicine, gynecology, pediatric medicine and surgery and so on. 3. Jin, who saw the negative form of pulse diagnosis[診脈] emphasized following symptoms over pulse diagnosis using the spirit of ‘finding truth based on truth[實事求是]' in "Maekgyeolcheonmi(脈訣闡微)", but emphasized 'the combination of pulse and symptoms[脈證合參]'. He understood pulse diagnosis as a defining tool for symptoms, and in "Seoksilbirok(石室秘錄)" simplified pulse diagnosis into 10 methods : floating/sunken(浮沉), slow/fast(遲數), large/fine(大小), vacuous/replete(虛實) and slippery/rough(滑澀). 4. Jin used 'large formulas(大方)' a lot that usually featured a large dose, and in " Bonchosinpyeon(本草新編)" he thought of the seven formulas(七方) and ten preparations(十劑) as the standard when using medicine. He did away with old customs and presented a 'new(新)' and 'extra(奇)' point of view. He especially used a lot of Insam(人蔘) when tonifying Gi and Geumeunhwa(金銀花) when treating sores and ulcers. 5. In the area of surgery Jin gave priority to the early finding and treatment of disease with internal treatment[內治] and was against the overuse of acupuncture. However records of surgical measures in a special situation like lung abscesses(肺癰) and liver abscesses(肝癰), and anesthetic measures using 'Manghyeongju(忘形酒)' and 'Singoiyak(神膏異藥)' and opening the abdomen or skull, and organ transplants using a dog's tongue are important data. 6. Jin stated the diseases of Gi and blood broadly. Especially in the principles of treating blood, blood diseases had to be forwarded[順] and Gi regulation[理氣] was the number one priority and stated the following two treatments. First, in "Jeonggiinhyeolpyeon(精氣引血篇)" of volume 6 of "Oegyeongmieon(外經微言)", for the rules for treating blood he stated the pattern identification of finding Gi in blood and blood in Gi. Second, he emphasized Gi regulation(理氣) in blood diseases and stated that the Gi must be tonifyed after finding the source of the loss of blood.

The treatment and prevention of periodontitis is focused on the reduction and the elimination of pathogenic bacteria, especially A. actinomycetemcomitans and black pigmented bacteria such as P. gingivalis. To prevent recurrent disease, the recolonization of these bacteria should be inhibited in the periodontal pocket. Since the replacement therapy was introduced in periodontics by Hillman et al, Jeong et al reported that hydrogen peroxide-producing Lactobacillus acidophilus V-20 completely inhibited P. gingivalis and A. actino - mycetemcomitans in vitro and mouth gargling with Lactobacillus acidophilus V-20 in periodontitis patients during the maintenance phase improved clinical condition and reduced the No. of P. gingivalis and A. actinomycetemcomitans at 4 weeks of treatment. Prior to replacement therapy with bacteria, dynamics of microbial colonization should be considered. This study was performed to evaluate the change in the viable cell number of Lactobacilli and P. gingivalis after oral administration of L. acidophilus V-20. In periodontal health, gargling increased the No. of Lactobacilli in saliva, buccal mucosa, supragingival plaque from the first week, which maintained for 2-3 weeks after gargling stop, and then returned to the undetectable baseline level at the ninth week. In the periodontal pocket of moderate periodontitis patients, daily irrigation for 1 week and weekly irrigation for subsequent 3 weeks decreased the viable cell number of P. gingivalis during the period of irrigation and increased the number of Lactobacilli, which was maintained from the second to the seventh week. L. acidophilus V-20 was isolated for the first 2 weeks of oral administration, and the 3 different strains of Lactobacilli were isolated continuously for remaining period and identified as L. ali - mentarius, L. casei subspecies casei and L. fructosus. The first two Lactobacilli strains completely inhibited P. gingivalis in vitro and all the isolated Lactobacilli strains reduced the artificial plaque formation by 55-63%. These results showed that mouth gargling or pocket irrigation with L. acidophilus V-20 increased the No. of intraoral Lactobacilli and caused to decrease in the No. of P. gingivalis. This suggests that the replacement therapy by these Lactobacilli might be useful in the maintenance care of periodontal patients.

Fibrodysplasia ossificans progressiva(FOP)는 연조직의 진행성 이소성 골경화를 특징으로 한다. 상염색체 우성 유전을 따르지만 대부분의 FOP 환자는 ACVR1 유전자의 새로운 돌연변이로 인해 나타난다. 아주 작은 외상조차도 연조직의 영구적인 골경화를 유발할 수 있기 때문에 일반적인 치과치료에 의해서도 합병증이 생길 수 있다. FOP 환자의 치과치료 시 전달마취, 과도한 근육의 스트레칭, 생검 등은 모두 금기이다. 현재까지 알려진 FOP의 효과적인 치료법은 없다. FOP는 유병률이 매우 낮으며 초기에는 오진되는 경우가 많아 부적절한 처치로 인해 증상을 더욱 악화시키는 경우가 많다. 따라서 조기진단 및 합병증 발생을 줄이기 위한 예방적 조치가 가장 중요하다. 본 증례는 서울대학교병원 소아정형외과에서 특발성 FOP로 진단을 받고 하악 좌, 우측 유중절치의 만기잔존을 주소로 소아치과에 의뢰된 8세 1개월의 남아에서 증상의 악화없이 치과치료를 시행하였기에 이와 관련하여 FOP환자의 특징적 소견 및 치과치료 시 고려사항을 고찰하기 위함이다.

This study aims at deriving any useful information necessary to strengthen the competitiveness for growth through empirical analyses on general hospital located in a province in order to countermeasure the opening and competition of medical markets. The characteristics of user were identified on the basis of disease groups under KCD in the research method. In addition, the analysis on the expenses of diagnosis and treatment was divided into the treatment progress and degree of hospital resource utilization And the regression was carried out to identify the impacts of characteristics of inpatient users on the degree of hospital resource utilization. As a result of major research, the inpatient users of the general hospital located in the provincial area in consideration of inpatient users were formed around the inpatient disease groups representative for Korea(diseases of the respiratory system, injury and poisoning & certain other consequences of external causes). And it was understood that most of residents within a distance of 40 minute by the public transportation were using. And mostly were under the age of 9 or over 60, and the provision of medical features such as the degree of consultation and operational functions were inadequate. When we classify inpatient treatment cost for each resource application as the medical cost being the center of patient care function, the equipment and human resource application sector are constituted over half. Accordingly, the following suggestions are made as plans to strengthen the competitiveness for the growth of general hospitals located in the provincial areas on the basis of analytical results. First, it is necessary to have the characterization matching to the age and disease groups with a high frequency. Second, it is necessary to increase the degree of hospital resource utilization according to the characterization. Third, it is necessary to concentrate on public relations. The above suggestion, as a method for securing image improvement and competitive power as a general hospital, and through expansion of social function that a regional general hospital needs to secure not only as an individual institution but also as a general hospital, it can be seen that a general improvement of image as a regional general hospital is possible.
