We present a case of intrapancreatic accessory splenic infarction in a 28-year-old woman. It was discovered during a workup for an acute right epigastric pain. Computed tomography imaging of abdomen demonstrated a hemorrhagic high attenuation with enhancing solid portion in the tail of pancreas. The clinical and radiological differential diagnosis included pancreatic mucinous cystic neoplasm, pancreatic endocrine neoplasm, solid pseudopapillary tumor, ductal adenocarcinoma, and metastasis. A distal pancreatectomy was completed. The microscopic examination revealed heterotopic splenic tissue with infarction and her abdominal pain disappeared. In this case report, we first describe a symptomatic accessory splenic infarction which presented as a hemorrhagic mass in the tail of pancreas mimicking pancreatic neoplasm.

Purpose: Evaluate the mold we have made to improve the reproducibility of the patient position and make homogeneous dose distribution to the treatment volume effectively when treating the patient who has hypervascular ulcer on her tongue caused by paraneoplastic autoimmune multiorgan syndrome by mold brachytherapy. Materials and Methods: The mold is consisted of upper and lower parts. We inserted 2 mm of lead sheet on the gums toward the oral cavity to protect them from unnecessary irradiation during the treatment. We had planned on orthogonal images obtained the patient. 200 cGy was delivered in every fraction with a total dose of 3000 cGy. To evaluate the effect of the lead sheet, we made a measurement with a phantom that has gums and tongue made of tissue with an equivalent material (bolus). Five of TLDs were placed on the interesting points of gums to measure the dose during irradiation with lead sheet and without lead sheet for three times respectively. Results: The result of the measurement without lead sheet are A: 33.9 cGy, B: 30.1 cGy, C: 31.8 cGy, D: 23.3 cGy, E: 24.1 cGy. The results of measurement with lead sheet are A: 20.6 cGy, B: 18.8 cGy, C: 19.6 cGy, D: 14.7 cGy, E: 15.1 cGy. Conclusion: Since we are using the mold made in our department during the treatment of the patient with hypervascular ulcer on tongue, we could deliver a proper dose to the treatment volume. In addition, the mold provided highly accurate and reproducible treatment and reduced the dose to the gums and teeth. Therefore, the possibility of side effects could be decreased significantly.

Purpose: The study is to check the specialty of radiotherapists working in the department of radiation oncology and find job satisfaction, organizational commitment and job commitment having an effect on professional parts. After making analysis of the mutual relation, it is to provide radiotechnologists with making progress in the future. Materials and Methods: From March 2 to March 30, we had carried out a survey with email. It is possible to have 272 questionnaires answered in the survey. We make use of SPSS 13.0 for Windows to analyze the data collected for study. Frequency and a percentage are meant to show general characteristics, and t-test and ANOVA to do the difference between general properties and professionalism. Pearson's correlation coefficient also is meant to do the correlation of professionalism, organizational job commitment and job satisfaction, and multiple regression analysis to do the factor for a relevant variable to affect professionalism. Results: There are subdivisions in the professionalism informing us of the self-regulation $17.74{\pm}2.32/3.55{\pm}.46$, a sense of calling $17.58{\pm}2.63/3.52{\pm}.53$, reference of the professional $17.14{\pm}2.39/3.43{\pm}.48$, service to the public $15.97{\pm}2.48/3.19{\pm}50$, and autonomy $15.68{\pm}2.28/3.14{\pm}46$. Grand mean turns out to be $83.89{\pm}7.63$(Summation of items)/$3.37{\pm}0.49$ (Numbers of items). When it comes to a statistical relation between general characteristics and professionalism, the statistics have it that these come within age (P<.001), period of employment (P<.001), education status (P<.05), a monthly income (P<.001), radiotherapists who get a special license (P<.001), the position (P<.001), and an opportunity for developing (P<.001). As a result of organizational commitment, job commitment, and job satisfaction, grand mean in organizational commitment proves to be $80.10{\pm}8.15/3.34{\pm}.34$. There are subvisions showing affective commitment $28.64{\pm}4.61$/3.58, continuance commitment $27.54{\pm}4.22/3.44{\pm}.53$, and normative commitment $23.95{\pm}2.94/2.99{\pm}.37$ in order of precedence. The average grade in job commitment is $32.47{\pm}5.77/3.30{\pm}.60$ and that in job satisfaction is $63.39{\pm}10.16/3.17{\pm}.51$, respectively. We find the positive relationship between professionalism and organizational commitment (r=.522, P<.05), between professionalism and job commitment (r=.444, P<.05), and between professionalism and job satisfaction (r=.507, P<.05). And we also get the positive relationship between organizational commitment and job commitment (r=.549, P<.05), between organizational commitment and job satisfaction (r=.433, P<.05), and between job commitment and job satisfaction (r=.462, P<.05). To catch the factors influencing the professionalism of radiotherapists, we used multiple regression analysis. According to the final model, it appears affective commitment (B=.755, P<.05), normative commitment (B=.305, P<.05), job satisfaction (B=.092, P<.05), an opportunity for developing (B=-1.505, P<.05), and the position (B=-1.155, P<.05) in order of precedence. It seems that explaining influece on $R^2$ is 0.504. Conclusion: The results of the factors that influence professionalism working as radiotherapists in the department of radiation oncology have it that the more affective commitment, normative commitment, and job satisfaction we feel, the more professionalism we recognize. We think that the focus of professionalism is increased if getting the chances for radiotherapists to have little to do with developing opportunities given.

김양수,이선영,임석건,곽근탁,박주경,이승훈,황호인,차석용,Gim, Yang-Soo,Lee, Sun-Young,Lim, Suk-Gun,Gwak, Geun-Tak,Pak, Ju-Gyeong,Lee, Seung-Hoon,Hwang, Ho-In,Cha, Seok-Yong 대한방사선치료학회 2009 대한방사선치료학회지 Vol.21 No.1

Purpose: We evaluated the device that was created for maintaining the patient's setup and protecting the testicles from scattered radiation during treatment of carcinoma of the penis. Materials and Methods: The phantom testicles were made of vaseline cotton gauze and the device consisted of 5 mm of acryl box and 4 mm of lead shielding. $3{\times}3\;cm^2$, $4{\times}4\;cm^2$, $5{\times}5\;cm^2$, $6{\times}6\;cm^2$, $7{\times}7\;cm^2$ field sizes were used for this study and measurement was made at 4, 5, 6, 7, 8, 10 cm from the lower edge of the field for 10 times with lead shielding and without the shielding respectively. 200 cGy was delivered using 6 MV photons. Results: The scatted radiation without lead shielding at 4, 5, 6, 7, 8, 10 cm from the lower edge of the field were 14.8-4.7 cGy with $3{\times}3\;cm^2$, 15.7-5.2 cGy with $4{\times}4\;cm^2$, 17.6-5.5 cGy with $5{\times}5\;cm^2$, 19.9-6.6 cGy with $6{\times}6\;cm^2$, 22.2-7.6 cGy with $7{\times}7\;cm^2$ and the measured dose without lead shielding were 7.1-2.6 cGy with $3{\times}3\;cm^2$, 8.9-3.6 cGy with $4{\times}4\;cm^2$, 12.3-4.8 cGy with $5{\times}5\;cm^2$, 14.6-5.0 cGy with $6{\times}6\;cm^2$ and 21.1~6.4 cGy with $7{\times}7\;cm^2$. As shown above, the scatted radiation decreased after using lead shielding. Depending of the range of field sizes, the resulting difference between without shielding values and with shielding values were: 7.8-1.1 cGy at 4 cm, 5.1-1.2 cGy at 5 cm, 3.8-1.1 cGy at 6 cm, 3.4-1.7 cGy at 7 cm, 2.8-1.7 cGy at 8 cm, 2.4-2.5 cGy at 9 cm and 2.1-1.8 cGy at 10 cm. In the situation as described above, the range in values depending on the distance was 7.8-1.1 cGy with $3{\times}3\;cm^2$, 6.9-1.6 cGy with $4{\times}4\;cm^2$, 5.3-0.8 cGy with $5{\times}5\;cm^2$, 5.3-1.5 cGy with $6{\times}6\;cm^2$ and 1.1-1.8 cGy with $7{\times}7\;cm^2$. Conclusion: Using the device we created to shield the testicles from scattered radiation during treatment of carcinoma of the penis, we have found that scattered radiation to the testicles is decreased by the phantom testicles, and by increasing the distance between the testicles and penis.

저자들은 중증 재생불량성빈혈로 동종 골수이식 및 추가적인 동종 말초혈액 조혈모세포이식을 시행 받은 후 만성 이식편대숙주질환이 발생하여 면역억제제로 조절되었으나 자가면역성 갑상선기능항진증이 병발한 1예를 경험하였기에 이를 보고하는 바이다. Chronic graft-versus-host disease (GVHD), which is a frequent complication following bone marrow transplantation (BMT), is characterized by fibrosis of the skin, liver, lungs, and gastrointestinal tract, immunodeficiency, and the production of autoantibodies. Endocrine dysfunction, in particular thyroid disease, has been described following BMT, but this has previously meant hypothyroidism secondary to total body irradiation or transfer of autoimmune hyperthyroidism from a donor with Graves’ disease rather than in association with chronic GVHD. We report a case of a 26-year-old man who developed Graves’ disease eight years after BMT and who had remission of chronic GVHD. He received an allogeneic BMT for severe aplastic anemia. Eighteen months after BMT, diarrhea and chronic GVHD developed and were treated with cyclosporine and steroid. Four years after ceasing the cyclosporine, the patient developed weight loss, palpitations, fever, and anterior neck swelling, and was diagnosed with Graves’ disease based on typical thyroid function tests. The signs and symptoms in the patient improved with propylthiouracil and propranolol.

저자들은 만성골수성백혈병으로 동종 골수이식과 이식편 부전으로 인하여 추가적인 말초혈액 조혈모세포이식을 시행 받은 환자에서 만성 이식편대숙주질환과 그 폐 합병증인 폐색성 세기관지염에 동반된 자발성 기종격동과 피하 기종이 병발한 1예를 경험하였기에 이를 보고하는 바이다. Obstructive lung disorders following after allogeneic bone marrow transplantation (BMT) in association with graft- versus-host disease (GVHD) contribute significant morbidity and mortality. We report a case of a 28-year-old man who developed spontaneous pneumomediatinum and subcutaneous emphysema complicating bronchiolitis obliterans after allogeneic BMT. He received an allogeneic BMT for chronic phase of chronic myeloid leukemia. Five months after BMT, he was boostered by allogeneic peripheral blood stem cells from the same donor due to graft failure. One month after the boostering, chronic GVHD developed and were treated with cyclosporine and steroid. The patients developed spontaneous pneumomediatinum and subcutaneous emphysema secondary to severe bronchiolitis obliterans 4 months after boostering donor cells. The air-leak syndromes were recovered by conservative management, including high-flow oxygen.

폐 결핵종과 감별이 어려웠던 폐 침윤성 비호즈킨 림프종

조상희,양태영,정익주,박무림,김형준,이제중,박형천,김여경,황호인 대한내과학회 2002 대한내과학회지 Vol.62 No.1

We report a 63-years-old woman who developed a nodular lesion in right upper lobe (RUL) of lung after achieving a partial response with salvage chemotherapy for relapsed non-Hodgkin's lymphoma (NHL). Previously, she had been diagnosed as NHL and tuberculous lymphadenitis resulting a complete response with 8 cycles of CHOP regimen and anti-tuberculosis medication for 1 year. CT scan of the chest showed an irregular marginated soft tissue density in RUL with internal punctate calcifications and this lesion was difficult to discriminate between pulmonary tuberculosis and parenchymal involvement of NHL. Because the pulmonary infiltrations progressed despite empirical anti-tuberculosis medication, we performed bronchoscopic biopsy, showing diffuse large B-cell lymphoma. Thereafter, the pulmonary infiltrations were markedly improved with salvage chemotherapy. However, she died of refractory NHL despite high-dose chemotherapy with autologous peripheral blood stem cell transplantation.(Korean J Med 62:109- 113, 2002)
