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.

The incidence of hematologic disorders in patients with Down's syndrome is significantly increased, about 14∼30 - fold higher than in general population and includes neonatal transient abnormal myelopoieis and acute leukemias. The age of onset of leukemia in Down's syndrome is peaking first in the newborn period and then under 4 years of age. Down's syndrome with acute leukemia above the age of 20 is very rare and it's treatment oucome is unclear. The treatment of Down's syndrome with leukemia has been controversial because of toxicity and associated congenital cardiac and other abnormalities. But if treated adequately, children with Down's syndrome show a favorable response to anti-leukemia therapy. A 24-year-old man with Down's syndrome was first seen for the evaluation of anemia and thrombocytopenia. The peripheral blood morphology and bone marrow study revealed acute myelogenous leukemia, cytogenetic study of bone marrow showed trisomy 21. Beacuse of his sicioeconomic condition and medical abnormalities including deafness, visual loss, he was treated with low dose subcutaneous cytosine arabinoside(Ara-C) for 11 days. Complete remission was obtained after 37 days. The complete remission lasted for 5 months. He subsequently relapsed, and died 6 months later.

Rheumatoid arthritis frequently involves the cervical spine and may lead to neurologic impairement. However, direct involvement of CNS structures by inflammatory cells has been reported infrequently. The prevalence of this complication of rheumatoid arthritis is unknown. Inflammatory CNS involvement in rheumatoid arthritis reportedly occurs in the setting of longstanding, active, erosive articular disease and is accompanied by extracranial and extraspinal nodules and vasculitis. This is diagnosed by radiologic finding of CNS nodules or meningeal thickening and by biopsy or autopsy. Treatment with corticosteroid, cytotoxic agent or surgical decompression is helpful. But the majority of patients die within several months of onset of neurologic symptom. Recently, we experienced a case of pachymeningitis caused by rheumatoid arthritis, which resolved repeatedly with azathioprine treatment.

The tidal currents and residual flows in Ulsan Bay were simulated and reproduced by a hydrodynamic model in order to prepare for the application to various real aspects such as the evaluations of coastal development, the constructions of breakwater and marine facilities, and navigation safety at sea, the prediction of pollutant distribution in water, and the monitoring or prediction of oil spill movement on sea surface. Comparing the computed with the observed tidal currents and residual flows in Ulsan Bay, the results of simulation of simulation were found to be good enough to satisfy the real applications.

상하악 중절치 간의 정중선 변위는 골격성 변위,치성 변위 및 골격성과 치성의 복합적 변위 등으로 구분된다. 그 중 치성 정중선 변위는 치열의 발육시기에 따라 다양한 방법으로 치료 방법을 선택할 수 있다. 특히 혼합치열의 초기에는 치열 내에 존재하는 공간의 조건,인접 영구치의 맹출 시기 또는 맹출 방향에 따라 영구 절치들의 위치가 자발적으로 변화,개선될 수 있다. 따라서 이러한 치아의 생리적 이동을 이용하여 특별한 교정장치의 이용 없이 치열 내에서 치아의 배열을 개선시킬 수 있다. 본 증례보고에서는 특히 유견치의 발거 시기 및 좌우 유치의 발거 순서 등을 이용하여 치성 정중선 불일치를 개선시킨 증례틀을 보고하고자 한다. A midline deviation is divided into three types, such as a skeletal midline deviation, a dental midline deviation, and a combination. Among them, the midline deviation which appear in the early mixed dentition without any skeletal problem can be managed differently by the stage of dental development. The location of the permanent incisors can be improved without using artificial force in consideration of the condition of the space, the eruption timing or the eruption path of the adjacent permanent teeth in early mixed dentition, especially when the permanent incisors are erupting. Therefore. the space supervision technique, which can have the teeth align themselves utilizing physiologic events such as sequence or timing of the eruption of permanent teeth, can be an alternative to orthodontic movement. This case report describes midline deviation improvement by space supervision.

현대 사회에서 증가하고 있는 산성 음료의 소비는 치아 부식의 원인으로 주목받고 있다. 이에 본 연구에서는 산성 음료와 산부식 용액,산성 음료 적용 후 칫솔질,산성 음료 적용 후 우유,타액, Tooth Mousse^(ⓡ) 의 적용이 치아 법랑질 표면 재광화에 미치는 영향을 평가하기 위해 사람 소구치의 치관 시편을 제작하여 각각을 적용시킨 후 scanning electron micrograph (SEM)를 촬영 한 결과 다음과 같은 결과를 얻었다. 1. Coca-Cola와 Chilsung-Cider의 산도는 FineEtch 37과 self-etching primer인 Tyrian™SPE의 산도보다 높았다. 2. Coca-Cola,Chilsung-Cider, FineEtch 37, Tyrian™SPE를 적용한 후 촬영한 SEM 사진에서 법랑질 표면의 부식된 양상을 비교한 결과 Coca-Cola와 Chilsung-Cider의 산부식 정도가 나머지 둘의 산부식 정도보다 낮은 양상을 보였다. 3. Coca-Cola. Chilsung-Cider를 적용한 후 우유,타액, Tooth Mousse^(ⓡ)를 적용시키고 촬영한 SEM 결과 모두 비슷한 양상을 보였으며 이는 부식된 법랑질 표면보다 덜 부식된 양상을 보였다. 4. Coca-Cola를 적용시킨 다음 칫솔질한 후와 Coca-Cola. 타액,칫솔질의 순서로 적용한 후 촬영한 SEM 결과,타액을 적용시킨 법랑질의 표면이 덜 부식된 양상을 보였다. It is widely believed that the increase in the prevalence of dental erosion is due to soft drinks. The purpose of this study was to assess the influence of soft drinks and etchant on the erosion of tooth enamel and the effect of tooth brushing on the abrasion of eroded enamel, and the effect of milk, saliva and Tooth Mousse"' on the remineralization. The changes in tooth enamel surface were observed by scanning electron microscophy. The results were as follows; 1. The pH of Coca-Cola and Chilsung-Cider were higher than the pH of FineEtch 37 and Tyrian™SPE. 2. The SEM photos revealed that the pattern of the surface eroded by Coca-Cola and Chilsung-Cider were more obvious than that eroded by etchants. 3. The results of remineralization by saliva, milk, Tooth Mousse^(ⓡ) were not different from each other. 4. The remineralization by saliva decreased tooth brushing abrasion.
