Central odontogenic fibroma (COF) is a rare benign tumor that accounts for 0.1% of all odontogenic tumors. A case of COF (simple type) of the mandible in a four-year-old boy is described in this report. The patient showed asymptomatic swelling in the right inferior border of the lower jaw for one week. A panoramic radiograph showed a poorly-defined destructive unilocular radiolucent area. Cone-beam computed tomography showed expansion and perforation of the adjacent cortical bone plates. A periosteal reaction with the Codman triangle pattern was clearly visible in the buccal cortex. Since the tumor had destroyed a considerable amount of bone, surgical resection was performed. No recurrence was noted.

Pulmonary cryptococcosis is rare in immunocompetent subjects. Here, we present the case of a 16-year-old boy who was referred to our pediatric department for the management of multiple consolidations detected on chest radiography, which was routinely performed when the patient was being evaluated for an ankle fracture. Fine needle aspiration biopsy was performed, and the definitive diagnosis was established as cryptococcal pneumonia. After 8 weeks of antifungal treatment, the pulmonary nodules on the chest radiographs disappeared.

Hemolytic anemia and thrombocytopenia are rare clinical manifestations of acute glomerulonephritis. Initially, in all such cases, a diagnosis of hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, systemic lupus erythematosus, and amyloidosis should be ruled out. The presence of hemolytic anemia and thrombocytopenia is rare, but possible, in a case of acute poststreptococcal glomerulonephritis, and may result in delayed diagnosis or misdiagnosis. Correct and timely diagnosis would ensure adequate treatment in such patients. We report of a 22-month-old boy with acute glomerulonephritis coexistent with hemolytic anemia and idiopathic thrombocytopenia.

Giant hydronephrosis (GH) is a rare urological entity and usually presents with more than a liter of fluid in the collecting system. It may mimic a progressive and benign abdominal cystic tumor. We report a case of GH in an 11-year-old obese boy who presented with abdominal distension and dyspnea on exercise. Hydronephrosis was caused by ureteropelvic junction obstruction, with 2,300 mL of fluid in the collecting system. Diagnostic and therapeutic features of this case are discussed, with reference to current literature.

We report three cases of posterior mediastinal tumor in Von Recklinghausen's disease on 12-yearsy old boy, 8-years-old girl and 6-years-old boy. Especially the last case was combinded with "Dumbbell" neurilemmoma of cervical spine. In the first case, preoperative CT scan showed a homogeneous large mass In the posterior mediastinum. But the mass did not show intraspinal invasion on the chest MRI scan. In the last case, cervical spine CT with thecal enhancement shows dumbbell shaped neurofibroma, compressed spinal cord and thecal sac In three cases we removed all the masses successfully and the patients were discharged safely without significant problem.t problem.

Purpose: The purpose of this study was to examine risk factors for sexual behaviors in Korean female high school students. Methods: Data was collected by a written questionnaire from June 22 to July 18, 2002 from 522 girls, who were stratified samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul, Korea. We conducted multiple regression analysis using the SAS pc＋ program. Results: Risk factors for intimate behaviors were association with boy friends, differential association, family attachment, and family abuse experience. These variables cause 68% of intimate behaviors. Risk factors for sexual experiences were differential association, association with boy friend, and family attachment. These variables cause 14% of sexual experiences. Conclusion: Efforts to reduce sexual behaviors in girls should include the possible role of peers and develop peer leader programs.

고품질의 경쟁력이 있는 상품을 지속적으로 생산하기 위해서는 각 작물별 적합한 배양토(토양조건) 선정과 과학적인 영양(비배)관리가 절실히 요구된다. 이미 선진국에서는 분화용 또는 재배용 배양토를 기능적으로 전문화하여 산업에 활용하고 있으며, 이 분야에 대해서 가축분뇨 등 폐자원을 이용한 배양토 생산이 실용화되고 있다. 국내에서 공정육묘용 상토와 화분용, 식물재배용 배양토에 사용되는 원료(피트모스, 펄라이트, 암면 등)는 거의 대부분 외국으로부터 수입에 의존하고 있으며, 국내의 대규모 기업형 축사 또는 돈사에서 발생되는 축분은 환경오염의 근원이 되나 충분히 부숙 또는 특수가공처리를 한다면 필요한 배양토 조제에 효율적이고 기능적인 자원으로 활용할 수 있을 것으로 평가되고 있다.

A 10-year-old boy with a history of epileptic seizure for 3 years, showed ataxia and left side weakness. In Brain MRI, hemiatrophy of the right hemisphere was noted. So we considered that he had a cerebral hemiatrophy caused by continued epileptic seizure and treated him with herbal medicine, acupuncture and physical therapy. We report a case of a 10-year-old boy who showed symptoms of a cerebral hemiatrophy caused by maintained epileptic seizure.
