Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy, and little is known concerning its Pathogenesis, optimal treatment, and prognosis. A 29-year-o1d pregnant woman (21 weeks) Presented with abdominal discomfort CA 19-9, CA 125, and CEA were normal Abdominal CT scanning revealed a 19x15x13 cm retropentoneal tumor Exploratory laparotomy and tumor excision were performed. Mucinous retropentoneal implants were removed as completely as possible Histologically, the tumor showed focal areas of capsular invasion, but free resection margins The uterus and both ovaries were normal in appearance No adjuvant therapy was pursued. Six months later, Peritoneal and bilateral ovarian metastases were discovered. Hence, we report the details of this case of primary retroperitoneal mucinous Cystadeno-carcinoma and present a review of the literature.

The purpose of this study was to evaluate the effect of the dentin pretreatment on the marginal leakage of a glass ionomer cement. In this study, 60 molars with sound and healthy crown portion were used. The dentin surface of these teeth were exposd and polished with 600 grit silicon carbide paper. Square-shaped cavities were prepared on the flattened dentin surfaces and these were divided in to 4 groups according to the dentin pretreatment procedures. Group Ⅰ : Dentin pretreatment with distilled water as a control group. Group Ⅱ : Dentin pretreatment with 5% sodium hypochlorite solution. Group Ⅲ : Dentin pretreatment with Ketac conditioner. Group Ⅳ : Dentin pretreatment with 40% polyacrylic acid. The degrees of dye penetration in the cavity walls were assessed using a stereoscope at x40 magnification according to the maximum dye penetration. The results were analyzed by using Mann-Whitney U test. The results were as follows : 1. All goups showed varying depth of dye penetration. 2. Distilled water group showed the most severe marginal leakage when compared with the other groups(P<0.05). 3. 40% polyacrylic acid group showed the least amount of marginal leakage compared with the other groups(P<0.05). 4. There were significant differences between Group Ⅰ(distilled water) and Group Ⅳ (40% polyacrylic acid)(P<0.05), but there were no significant differences among Group Ⅰ (distilled water), Group Ⅱ (5% sodium hypochlorite), Group Ⅲ (Ketac conditioner)(P>0.05)

Background : Through many researches, microsatellite is expected to be a good diagnositic and prognostic factor in colorectal cancer, endometrial cancer, gastric cancer, and the others. The prevalence of microsatellite instability (MSI) in gastric carcinoma has reported variously, 13~44%. Purpose : We aimed to determine the prevalence of MSI-high and the relationship between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma of stomach. Material and Methods : We analyzed 106 sporadic intestinal type adenocarcinoma specimens excised from patients who were over thirty-five years old to determine the statue of microsatellite by DNA sequencing. The tissues were formalin-fixed and paraffin embedded. DNA were extracted and amplified by polymerase chain reaction (PCR). MSI was determined using five markers recommended by National Cancer Institute (NCI). Specimens were also studied with five patholical factors-differenciation of tumor cells, depth of invasion, lymph node metastasis, vessel invasion, and perineural invasion- to determine pathological state. Result : The microsatellite statue was determined as MSI-High in 5 cases (4.7%), no MSI-low, and MSS (microsatellite stable) in 101 cases (95.3%). Within the frequency, there was no large gap in the distinction of gender in MSI cases, but in MSS cases, there was three-times more cases in male. MSI cases had moderate-to-poor differenciation and trend to invade toward serosa. All MSI cases showed no perineural invasion. But we could not find any statistical significance between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma. Conclusion : Results suggest that MSI can not make any certain pathological significance in sporadic intestinal type adenocarcinoma. Even though less than 5% of sporadic intestinal type adenocarcinoma patients showed MSI, it can be used as a influential prediagnostic factor of gastric cancer. Further study with large scale of cases will be followed to verify these results.

인체의 골수는 간엽모세포를 함유하고 있으며 이들은 골수미세환경의 주된 세포들로 분화가 가능하여 조혈기능을 지지한다. 본 연구에서는 성별이 다른 동종조혈모세포이식 환경에서 조혈모세포의 완전 생착을 보이고, 이식 후 1년에서 8년이 지난 11예의 재생불량성 빈혈 및 백혈병 환자들을 대상으로 하여 골수에서 MSC를 분리하고 체외 확장을 통해 배양된 MSC에서 X 염색체 탐식자를 이용한 FISH 및 microsatellite polymorphism PCR 기법으로 그 기원을 확인하였다. 그 결과 조혈모세포는 완전히 공여자 기원으로 대치되었음에도 불구하고 MSC는 모두 수여자 기원임을 알 수 있어, 동종조혈모세포이식에서 미세환경의 구축은 수여자의 자가 생산에 의한 골수 간질세포에 의한 것으로 생각된다. Background: Human bone marrow (BM) contains mesenchymal stem cells (MSC) that can differentiate into various cells of mesenchymal origin. It remains a matter of controversy whether donor-derived stromal cells are capable of engraftment following hematopoietic stem cell transplantation (HSCT) or not. Methods: To determine if donor-derived stromal cells are transferred to the recipients of allogeneic HSCT, we investigated the characterization of MSC in 11 patients 1 to 8 years after sex mis-matched allogeneic HSCT in severe aplastic anemia and leukemia. Results: All patients had complete engraftment with donor- derived stem cells as shown by detection of donor type DNA in peripheral blood mononuclear cells. Following culture, MSC showed the expression of SH2 and SH4, but none of the hematopoietic markers of CD14, CD34, or CD45. MSC which can be differentiated to osteogenic lineage showed the genotype of recipient completely using FISH or PCR analysis. Conclusion: This study confirmed that MSC isolated from recipients of allogeneic HSCT in severe aplastic anemia and leukemia are not of donor genotype despite of full hematopoietic engraftment with donor type. Donor cells did not contribute to reconstitute the marrow microenvironment.

Hearing impairement in varying degrees constitutes one of the most common disabilites affecting school aged children. Eight out of every 1,000 students under the age of twenty have significant hearing loss. Hearing disabilities range from slight to total loss of sound perception. Statistics indicate that only one out of every ten hearing impaired children will become deaf. Most motor activities can be included students may possess low levels of static and/ or dynamic balance, but the greatest majority possess normal motor and physical capabilities. All the hearing impaired youngsters should be properly assessed and given the identical testing batteries as normal children. Hearing impaired students have, essentialy, a communication handicap and suffer from inability to understand verbal instructions. All physical educators should be able to use minimal finger spelling and signing for hearing impaired students.

중증 재생불량성 빈혈 환자에서 신우신염에 대한 광범위항생제치료 중에 속발한 Saccharomyces cerevisiae 진균감염 1예

Most patients with aplastic anemia who do not respond to immunosuppressive treatment or are not candidates for bone marrow transplantation die of infection or bleeding. The neutropenia in acute leukemia, aplastic anemia, or occurring subsequently to chemotherapy and bone marrow transplantation increases susceptibility to infection. In general, the number of infectious episodes correlate with the degree and duration of neutropenia. Global immunosuppression produced by conditioning for bone marrow transplantation or graft-versus-host disease, is associated with unusual bacterial and fungal pathogens, or serious viral and protozoan infections. In addition, repeated treatment with broad-spectrum antibiotics is associated with the emergence of resistant organisms and fungal diseases because of the altered microbial microenvironment of the host. The incidence of invasive fungal infection caused by Saccharomycetes eerevisiae in immunosuppressed patients is very rare, compared with that of infection by candida or aspcrgillus species. Cases of Saccharomycetes cerevisiae fungemia occurring in the course of treatment with broad-spectrum antibiotics are reported in patients with extensive burn or with prosthetic valve endocarditis. We experienced a case of urinary tract infection by Saccharomycetes cerevisiae in a 27-year old female patient with severe aplastic anemia. We report the case with a review of relevant literatures.
