목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

많은 연구에서, 유치와 그 계승 영구치의 선천적 결손 간에는 상당한 연관관계가 있는 것을 보고하였다. 그러나 하악 전치부에서, 유치의 선천적 결손에도 불구하고, 그 계승 영구치는 정상적으로 존재하는 증례가 임상적으로 종종 관찰되기도 한다. 본 연구의 목적은 한국 어린이에서 하악 유절치와 그 계승 영구치의 선천적 결손 간의 상호 연관관계를 평가하는 데에 있다. 2005년 1월 1일부터 2008년 9월 5일까지 서울대학교치과병원에 내원하여 파노라마 방사선사진을 촬영한 6세 이하의 남녀 어린이 총 14,307명을 대상으로 하악 전치부의 치아양상을 관찰하여 유치와 영구치의 선천적 결손 관계를 평가하여 다음과 같은 결과를 얻었다. 1. 하악 유절치의 결손률은 0.24%였으며, 하악 유절치가 존재 시 후속 영구치가 존재할 승산(odds)은 7163.5였으며, 유절치의 결손 시 후속 영구절치가 존재할 승산(odds) 0.79였다. 2. 하악 유절치 결손의 증례 중 후속 영구치가 모두 존재하는 경우는 44.12%였다. 유절치의 양측 결손 시 후속 영구치가 하나라도 존재할 승산(odds)은 유절치 편측 결손 시에 비하여 1.57 배였다. 3. 유절치 결손이 있을 때 유절치의 편측 결손일 승산(odds)은 여자가 남자에 비해 2.2 배였다. 또한, 유절치 결손이 있을 때 후속 영구절치가 존재할 승산(odds)은 남자가 여자의 경우에 비하여 2.22 배였다. Many studies have shown that there is a strong relationship between the congenitally missing primary teeth and their succedaneous permanent teeth. However, especially in case of lower anterior region, we can observe the existence of permanent teeth even though their precedent primary teeth were missed at times. The purpose of this study was to reveal the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth in Korean children. Total of 14,307 children, under 6 years of age, who attended the department of pediatric dentistry, Seoul National University Dental Hospital, Seoul, Korea from January 1st 2005 to September 5th 2008 were radiologically examined using the panoramic x-ray in order to analyze the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth. The results were as follows : 1. The prevalence of congenitally missing lower anterior teeth in primary dentition was 0.24%. The odds ratio of both the primary and permanent anterior teeth being present was 7163.5 and only the permanent anterior teeth being present was 0.79. 2. The percentage of all succedaneous permanent teeth being present was 44.12% in cases of missing lower primary anteriors. The odds ratio of at least one succedaneous permanent teeth being present in cases of bilateral primary anterior teeth missing was 1.57 times more common than in cases of unilateral primary teeth missing. 3. The odds ratio of primary missing teeth being unilateral was 2.2 times higher in females. Moreover, the odds ratio of succedaneous permanent teeth being present in cases of primary teeth missing was 2.22 times higher in males.

Tracheobronchopathia osteochondroplastica (TPO) is a rare benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. Although some disorders were reported combined with TPO, these seemed to be considered casual. We report a case of TPO that combined with adenocarcinoma of lung. She was 50-year-old non smoking woman presented with chronic cough with right chest pain. Lung mass on right lower lobe was found on chest x-ray, so lung cancer was suspected. Multiple scattered whitish small elevations from trachea to bronchial trees were found on bronchoscopic exam. We mistook these lesions for metastases from lung cancer and biopsies of these lesions were done. Transbronchial biopsy for right lower lobe mass lesion was also done. But biopsies from trachea and bronchus revealed TPO rather than lung cancer. Transbronchial lung biopsy of right lower lobe mass was diagnosed adenocarcinoma of lung. So TPO combined with adenocarcinoma of lung was diagnosed.

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP, The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-l0,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

The purpose of this study is to do two things: first, to elucidate the significance of in-service training for teachers of English; second, to find an answer to the programme of in-service training that senior teachers of English propose to meet their needs in their profession. The former was done through the study of the literature dealing with in-service education, particulary for teachers of English, and the latter through a questionnaire to be answered by the teachers of English in mid-career. At the present time, it is to some extent true that in Korea the main stage of English teaching is the secondary sohool, whose teachers of English must be the basis for English education. In addition, educational social change has brought a new attitude to teaching and learning of English, and technological change electro-mechanical equipment and its associated techniques into the classroom. To be brief, teachers of English must remain abreast with recent developments in English education. As for the specific programme for the in-service training, its contents above all things must be connected with the new mechanical aids and the things that teachers of English need in their profession and in which they are unlikely to have had any training during their initial training. In order to do this, it is a sine qua non that we should make use of the opinions and ideas about the in-service training that its participants suggest. The reason is that most of them have not only a lot of teaching experience but also sound knowledge of fundamental academic disciplines of linguistics, psychology, English teaching, and so on; moreover, they can usually judge what is and what is not relevant to them in their profession. Summing up, the materials gained from them have come to the following result. The courses they took in the past in-service training were under a bias toward theoretical speculative ones. Therefore, the courses they want to take are practical, descriptive, and theoretical ones in that order. From what has been mentioned above, the courses of in-service training for teachers of English can be seen to have three interrelated aspects: the practical aspect, the descriptive aspect, and the theoretical aspect. What I wish to suggest finally here is that any in-service training cannot be effective without the participants' strong willingness to learn, a desire to promote their professional growth.
