Ameloblastic fibro-odontoma consists of ameloblastic fibroma combined with an odontoma. Ameloblastic fibro-odontoma affects somewhat younger patients than ameloblastic fibroma and 62% of patients are younger than 10 years. Clinical, radiologic, and histologic studies were performed in 9-year-old child of ameloblastic fibro-odontoma. Location of the lesion was the upper molar area. Radiographically, the opaque odontomatous tissues was observed in a circumscribed, but otherwise radiolucent area. Histologically, typical ameloblastic fibro-odontoma was associated with the calcifying or calcified dental tissues of an odontoma. In this paper, a case of ameloblastic fibro-odontoma of the maxilla and a review of the literature is presented.

연구목적 : 본 연구는 국내 노인의 습관을 조사하고 불면 증상과 연관 있는 인구학적, 질병학적 요인을 알고자 했다. 방 법 : 1997년 12월부터 1998년 1월까지 약 1개월에 걸쳐 2단계 층화집락표본추출의 역학조사법을 통해 선정된 3개 4개동 거주의 만 65세 이상 노인을 대상으로 수행되었다. 대상자 중 723명에서 등답을 받았으며 응답률은 73.8였다. 대학생인 설문조사요원들을 훈련시킨 뒤, 이들로 하여금 대상지역의 노인거주가정을 방문하여 개개 노인을 대상으로 반구조화된 면담으로 수면습관 및 불면증상 설문을 실시하였으며 그 외 한국어판 노인정신장애평가척도, 삶의 질 척도를 이용한 설문조사와 과거 질병력을 청취조사하게 하였다. 결 과 : 국내 노인들은 평균 오후 10시 16분에 자리에 누워 오전 5시22분에 일어나서 총 7시간 6분의 수면시간을 보였다. 노인의 11.7%가 거의 매일 밤 불면증을 14.8%가 간헐적 불면증을 호소하였다. 남자에서는 연령이 증가할수록 침상에 누워있는 시간이 증가하고, 또, 입면시까지 소요되는 시간과 수면 중의 각성회수가 증가되었으나 여성에서는 명확하지 않았다. 단변수 분석에서 요통, 중풍 병력의 환자에서 불면증상이 심했다. 다변량분석 결과 불면 증상과 관련 깊은 요인으로 남자에게서는 고령과 우울증상이 여자에게서는 남자의 위험요인에다 신체통증과 피부병력이 추가로 관련이 있었다. 결 론 : 지역 거주 노인에서 불면 증상은 매우 흔한 증상이며 우울증상과 명확한 상관관계를 보이고 있었다. 불면증을 극복하기 위해 불면증 위험요인의 인과관계에 대한 추후 연구가 필요하다. Objectives : The purpose of this study is to analyze sleep habit and investigate the association between insomnia and demographic, health and psycho-behavioral symptomatology in Korean urban elderly Method : A total of 723 community residents aged 65 years or older were surveyed by two stage, random cluster sampling method. The response rate was 76.2%. Interviewers performed door to door visits and administered a questionnaire about sleep, past medical history, and several scales as the Psychogeriatric Assessment Scale(PAS), the short form Quality of Life Scale (SF-36) and etc. Results : The mean scores are as follows : retiring time was ten-sixteen p.m., wake-up time was five twenty two a.m., duration of sleep was seven hours and six minutes. Among the elderly, 11.6% and 14.8% of the subjects reported chronic and intermittent difficulty in sleeping, respectively. The patients with back pain and history of stroke complained of more insomnia symptoms in univariate analysis. In ANCOVA analysis, insomnia symptoms were associated with an old age, depressive symptoms in male. Bodily pain and history of dermatologic disease were additional risk factors in female. Conclusions : The data suggest insomnia is one of most common health problems among elderly Koreans living in the community. Strong positive relationship between depressive symptoms and insomnia were found. Further research is needed to explore the causal relationship between insomnia and risk factors.

Background: Intratumoral injection of OK-432 produced significant antitumor effects. There are reports that OK-432 was injected directly into tumor tissue on gastrointestinal tracts and HCC tissue, producing decrease in serum alpha-fetoprotein level. We adopted this technique for treating locally advanced lung cancer. The object of this study is to evaluate the local therapeutic efficacy, side effects of injection for treating symptomatic mass. Methods: Twenty lung cancer patients (13 males and 7 females) underwent sonography guided OK-432 injection. We analyzed relationships between response of OK-432 and response of skin test, histology and age. Pain that patients feel was evaluated by VAS (Visual Analog scale). Results: A significant decrease of tumor size was observed. The mean pre-injection diameter of the lesions was 54.7±11.3mm, PR rate were 15.0% (3/20) and minimal change (50%<tumor size decreased.) patients were 35.0% (7/20). The VAS score before injecting OK-432 into the lesion was 5±3, this was decreased to 2.5±1.5 (p=0.04). Object response was significantly correlated with skin response, adenocarcinoma, and age. Conclusion: A significant decrease of tumor size and pain was observed. So OK-432 is a valuable treatment option for patients with symptomatic lesion from advanced lung cancer who are not amenable to further therapy.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

Background : Diagnosis of peripheral pulmonary lesion by conventional bronchoscopy is still challenging. The sheathed bronchial brush has been used to collect samples from the visible endobronchial lesion. Recently developed endobronchial ultrsonography (EBUS). can obtain image of peripheral pulmonary lesion at bronchus suspected by bleeding sign of sheathed brush. This study evaluated availibility of detected lesions by bleeding after bronchial brushing in pheripehal pulmonary lesions before transbronchial lung biopsy Methods : Between August 2006 and November 2008, 50 patients(38 men and 12 women, median age, 65 yrs) whose peripheral pulmonary lesions could not be detected with flexible bronchoscopy were included in this study. Among 50 patients, 40 cases were malignant lesion(non-small cell carcinoma 35, small cell carcinoma 5), and 10 cases were benign lesions(inflammatory disease 7, others 3) Results : Of the 50 patients, lesions detected bleeding after bronchial brushing was 34 cases(68%) and lesions detected by EBUS was 33 cases(66%). Sensitivity was 90.0-95.4%, Specificity was 83.3-80%, Positive predictive value(PPV) was 83.3-95.4% and Negative predictive value(NPV) was 80-90.9%. Diagnostic rates in visualized lesion by EBUS and otal peripheral lesions were 75%(25/33), 58%(29/50) respectively. There was no significant complication related with bronchial brushing. Conclusions : Bleeding sign by bronchial brushing was safe and effective method to predict location of peripheral pulmonary lesion with sufficient diagnostic yield

뇌졸중, 파킨슨 병, 척수신경손상 등으로 연하관련 근육들의 협동운동장애가 발생한 환자에서 흡인성 폐렴이 반복되거나 경장영양이 곤란하게 된다. 이러한 경우에 경피내시경하 위루술(percutaneous endoscopic gastrostomy)은 이들 환자의 생명을 유지하는데 매우 중요한 역할을 해 왔다. 위궤양 혹은 위암 등으로 위절제술을 받은 환자에서 위루술 대신에 부득이 경피내시경하 공장루술(direct percutanous endosopic jujunostomy)이 시행되었던 경우는 국내외에 몇 례의 보고가 있다. 본 증례는 과거 후두암 때문에 후두부식도절제술 후 결장 끼어듬(colon interposition) 수술을 받은 65세 남자 환자로 최근 좌측중대뇌동맥 경색으로 연하장애가 발생되었다. 저자들은 이 환자에게 지속적인 영양공급을 위하여 경피내시경하 결장루술을 합병증 없이 시행하였기에 보고하는 바이다. Dysphagia is a loss of coordination in the swallowing musles. It has occurred in patients with cerebrovascualr accident, head injury, Parkinson's disease or cervical cord injury. Dysphagia results in nutritional deficiency or repeated aspiration pneumonia. Percutaneous endoscopic gastrostomy have helped these patients to maintain healthy and save lives. Several cases of direct percutaneous endoscopic jejunostomy have been reported in patients who received gastric resection for a stomach cancer or peptic ulcer hemorrhage. A 65-year-old male patient, who was suffering from dysphagia, whose symptom was caused by left middle cerebral infarction. He was referred to the division of gastroenterology for the provision of permanent enteral feeding. His esophagus had been resected and replaced with a part of colon because of laryngeal cancer 5 years ago. We could not approach the stomach because the angle of anastomosis was acute and the colonic graft was long. We performed direct percutaneous endoscopic colostomy without any complications. Herein, we report on this successful case.
