Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

최병재,고동현,김성오,이제호,손흥규 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.3

외상성 교합은 교합력의 결과로서 치주조직에 가해지는 손상이다. 주된 증상은 치아의 동요도이고, 통증, 타진에 민감, 열에 민감한 증상이 동반될 수 있으며 교합력에 의해 치아가 이동을 할 수도 있다. 만성으로 진행시 치아의 과도한 교모가 나타나며 방사선학적으로 치근막 공간의 비후, 치조백선의 비후, 치조골의 방사선 투과성, 치근흡수 등이 나타날 수 있다.외상성 교합은 치주질환의 원인과 관련되어 있다. 증가된 치아동요도를 야기하며 외상성 교합 자체는 치은염과 치주낭을 발생시키지 않으나 국소적 치태와 염증이 존재하고 있는 하에서 골소실, 치주낭이 발생할 수 있다. 치은퇴축은 외상성 반월, 맥콜스 팽윤, 스틸만 균열의 형태로 나타난다. 본 증례는 하악 유견치 부위의 치주질환을 주소로 내원한 5세 남아로서 상하악 유견치의 조기 접촉에 의해 하악 좌우측 유견치의 중증도의 동요도, 교합마모, 치은 퇴축, 치조골 파괴의 증상이 나타났기에 보고하는 바이다. Trauma from occlusion(TFO) is injury to the periodontal tissue as a result of occlusal forces. Mobility is a common clinical sign of occlusal trauma. In acute occlusal trauma, this may be accomanied by pain, tenderness to percussion, thermal sensitivity, and pathologic tooth migration. Chronic occlusal trauma may be marked by excessive wear and gingival recession. Radiographic finding include a widened periodontal ligament space, radiolucence and condensation of the alveolar bone, and root resorption. TFO is related to the pathogenesis of periodontal disease. It can cause increased tooth mobility. TFO itself does not initate or aggravate marginal gingivitis or initiate periodontal pockets. Active trauma can accelerate bone loss, pocket formation and gingival recession depending on the presence of local irritants and inflammation. Gingival recession associated with occlusal forces includes traumatic crescent, McCall's festoon and Stillman's cleft. TFO plays a minor role in the pathogenesis of early to moderate periodontitis. A 5-year-old male visited Yonsei University Pedodontics clinic with a chief complaint about gingival recession. Mobility, excessive wear, gingival recession were detected by clinical exam on the both mandibular deciduous canine. On the radiographic view, vertical alveolar bone loss was observed on both mandibular deciduous canine.

The purposes of this study were to identify the detection and incidence of tetracycline resistance determinant tet(M) by PCR method and to evaluate the availability of PCR method guided for clinical use of antibiotics in dentistry. Subgingival plaque samples were collected from 172 sites of 29 patients. Both original sample and subculturd sample, PCR amplification was used to detect tet(M) in Fusobacterium nucleatum. The percentage of tet(M)-positive subjects and sites in original samples were 100%, 95.9%, respectively. And the percentage of tet(M)-positive subjects and sites in subcultured samples were 17.2%, 3.5%, respectively. In subcultured samples, probing pocket depth and clinical attachment level in tet(M)-positive sites were higher than in negative sites (p<0.05). The sensitivity and specificity of PCR method compared with broth dilution method as a gold standard were 0.91 and 0.86, respectively. The results suggested that tet(M) assay using PCR method was available to detect the tetracycline-resistant F. nucleatum.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

자궁경부 종양에서 Nested PCR을 이용한 인유두종 바이러스 16형 및 18형의 검출과 임상적 의의

최규연,이종국,최승도,배동한,김휘준,김민관 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

The aim of this study is to estimate the prevalence of HPV types(16, 18) in cervix of gynecologic patients and to elucidate the relationship of HPV types(16, 18) and clinical characteristics. Human papilloma virus(HPV) has attracted attention as one of the viruses linked to human cancers. Numerous clinical, epidemiological, and molecular studies indicate that certain genital HPV types are associated with cervical carcinoma. Of 100 types of HPV identified today, at least 40 have been found in the anogenital mucosa. A classification of these types into three groups with differing pathogenicity has been proposed: HPV type 6, 11, 42, 43, and 44 are detected more frequently in benign lesions such as condylomata; HPV type 31, 33, 35, 51, 52, and 58 are found more often in low grade squamous intraepithelial lesions than invasive lesions; and HPV 16, 18, 45, and 56 are predominant in high grade squamous intraepithelial lesions and invasive carcinoma. To detect HPV types prevalent in carcinoma of the uterine cervix, a type-specific, sensitive polymerase chain reaction(PCR)-based assay for HPV types 16, 18 was applied to 18 cervical carcinomas(15 squamous cell carcinomas and 3 adenocarcinomas), 21 cases of cervical intraepithelial neoplasia(CIN), and 42 samples of cervicitis and histologically normal. DNA extraction from cervical swab was done using DNAzol™(MBI, USA) and Nested PCR was done using HPV detection kit(Bioneer, Korea). The amplified product was analyzed directly on the basis of the site of ethidium bromide-stained band visible after agarose gel electrophoresis. The results were as follows 1. The positivity rates of HPV type 16 and HPV type 18 were 12.5%(90/718), 2,5%(18/718). so, HPV 16 positive cases(12.5%) was five folds as HPV 18 positive cases(2.5%) 2. Forty eight percents(39/81) of HPV 16 or HPV 18 positive cases were CIN, microinvasive cancer. 3. Age, Gestation number, Clinical stage, Histologic cell type in relation to HPV types were not statistically significant.

조혈모세포이식 환자에서 침습성 진균 감염에 대한 이트라코나졸 액과 플루코나졸 시럽의 예방 효과 : 전향적, 무작위, 비교 임상시험

최수미,이동건,최정현,박선희,엄기성,김유진,김희제,민창기,유진홍,김동욱,이종욱,민우성,신완식,김춘추 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 조혈모세포이식 환자에서 호중구 감소 기간 동안 이트라코나졸 액(ITZS)과 플루코나졸 시럽(FCZS)의 진균 감염에 대한 예방 효과를 전향적으로 비교해 보고자 하였다. 재료 및 방법 : 2001년 8월부터 2002년 6월까지 가톨릭 조혈모세포이식센터에 입원하여 동종 조혈모세포이식을 받은 만 18세 이상의 환자들을 각각 ITZS와 FCZS군으로 무작위 배정하여 침습성 진균 감염 발생과 약제 관련 부작용을 전향적으로 조사하였다. 결과 : ITZS군에 40명, FCZS군에 38명이 배정되었고, FCZS군 환자의 평균 나이가 더 많았다. 시험 약제 평균투여기간은 ITZS군 16.4일, FCZS군 21.9일로 ITZS군이 더 짧았다. 이는 ITZS군에서 소화기 부작용으로 인한 약제 중단이 더 많았기 때문으로 보인다. 시험 약제 투여 후 총 빌리루빈 수치의 유의한 증가가 관찰되었으나, 약제 관련 부작용은 모든 환자에서 가역적이었다. 호중구감소 기간동안 표재성 진균 감염은 두 군에서 모두 발생하지 않았고, 침습성 진균 감염은 ITZS군 5명(12.5%), FCZS군 8명(21.1%)으로 FCZS군에서 많았으나, 통계학적으로 유의하지 않았고, 사망률에도 유의한 차이는 없었다. 결론 : 침습성 진균 감염에 대한 이트라코나졸 액과플루코라졸 시럽의 예방 효과에 유의한 차이는 없었으나, 앞으로 더 많은 환자를 대상으로 잘 짝지어진 대조군 연구가 필요할 것으로 보인다. 부작용 중 간독성과 관련하여 이식시 투여되는 여러 약제들과의 상호작용에 대한 연구도 필요할 것이다. Background : Though fluconazole is widely used for antifungal prophylaxis, it is ineffective against mould infections including Aspergillus species. Itraconazole has a broader spectrum than fluconazole but the capsule form shows erratic bioavailability in neutropenic patients. In this study, we compared itraconazole oral solution (ITZS) with fluconazole syrup (FCZS) for the prevention of invasive fungal infection (IFI) in allogeneic hematopoietic stem cell transplant recipients. Materials and Methods : Adults receiving allogeneic hematopoietic stem cell transplantation (HSCT) from september 2001 to June 2002, were randomly allocated to either the ITZS group or the FCZS group. We prospectively evaluated the safety and efficacy of each drug. Results : Out of 78 patients (40 patients in the ITZS group and 38 patients in the FCZS group) who were eligible for this study, 37 patients completed the course of prophylaxis without any evidence of IFI. The mean duration of prophylaxis was 16.4 days for the ITZS group and 21.9 days for the FCZS group (P<0.006). Drug-related adverse events occurred in 28 patients (70.0%) and 19 patients (50.0%) in the ITZS group and the FCZS group, respectively. Common adverse events of ITZS were nausea, vomiting, and diarrhea. Drug-related reversible hepatotoxicity occurred in 4 patients in the ITZS group. There was a significant elevation of total bilirubin level in the ITZS group. The incidence of suspected IFI occurred in 5 patients (12.5%) who received ITZS, compared with 8 (21.1%) who received FCZS (P=0.372). There were no proven IFIs or superficial (oral/vaginal) fungal infections in both groups. Overall mortality was not different between the two groups (2.5% in the ITZS group versus 5.3% in the FCZS group, P=0.610). Conclusion : ITZS and FCZS showed similar protection against IFI during pre-engraftment period. Poor tolerability due to gastrointestinal troubles of ITZS might limit its success as prophylactic therapy. Well matched controlled study with large number of patients will be required in the future.
