Mandibular condylar fracture is common in mandibular fractures. Unlike other facial, skeletal fractures, most of mandibular condylar neck or head fractures are treated with closed reduction and subsequent functional therapy is essential for preventing complications including ankylosis, arthrosis and growth disturbance. From January, 2000 to September, 2002, we have treated 15 cases of mandibular condylar fractures with closed reduction by using functional appliance with bite block. Among these cases, we report a case of 14-year-old female with mandibular condylar neck fracture, resulted in good clinical and radiographic progress.

BACKGROUND AND PURPOSE: Radioopaque lesions are commonly seen in patients who received thoracic radiotherapy for various kinds of thoracic neoplasm, But therir exact diagnos are sometimes uncertain. PATIENTS AND METHODS: We examined simple chest radiograph and computed tomogram(CT) of 69 patients who received thoracic radiotherapy for lung cancer and were follow up at least 6 months in Yeungnam University Medical Center. RESULTS: Of the 69 patients. thirty-eight patients showed radioopaque lesions in their chest radiographs except radiation fibrosis; radiation pneumonitis was witnessed in 24 patients. infectious pneumonia in 8 patients, and recurrence in 6 patients. In radiateionpneumonitis patients, the pneumonitis occurred usually between 50 to 130 days after receiving radiation therapy, and interval between pneumonitis and fibrosis is 21 to 104 days. Simple chest radiographs of radiation pneumonitis(24 patients) represented ground glass opacities or consolidation in 4 cases(type I, 17%), reticular of reticulonodular opacities in 10 cases(type II, 42%), irregular patichy consolidations in 2 cases( type III, 8%), and consolidation with fibrosis in 8 cases(type IV, 33%), CT represent ground glass opacities or consolidation in 5 cases(type I, 29%), irregular nodular opacities in 3 cases(type II, 19%), irregular opacity beyond radiation fields in 3 cases(type III, 18%), and consolidation with fibrosis in 6 cased(typeIV, 35%). The CT of four patients who represented type II on simple chest radiographs reveal type I and III, and CT of two patients with clinical symptoms who had no abnormal finding on simple radiograph revealed type I. CONCLUSIONS: In conclusion, computed tomogram is superior to the simple radiograph when trying to understand the pathologic process of radiation pneumonitis and provide confidence in the diagnosis of radiation induced lung disease.

BACKGROUND: Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. MATERIALS AND METHODS: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. RESULTS: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. CONCLUSION: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.

Choe Han-Ki was a philosopher of the 19th century who resided in Seoul. He accumulated vast amount of knowledge of Western science and on the basis of them he built his own philosophical system different from those of the philosophers before him. Not only has he wrote books on philosophy, but many books on science as well. Among them Shin-Ki-Chon-Hum is a very unique medical book which reveals his original medical philosophy. He acquired medical knowledge through the medical books put into Chinese by missionary doctor Hobson and on the basis of them he criticized traditional medicine. He criticized traditional medicine because it explained vital phenomenon through the reductionist theory, such as Oh-Haeng(theory of five phases). And he also criticized it because it lacked in exact anatomical knowledge and that the exact origin of the disease was not known and it had limitations on treatment. He also criticized Western Medicine because it supposed God as a creator. He saw the possibility of communication between Western Medicine and traditional medicine. He didn't regard medicine as concerning disease and health only, but it included everything in it. His philosophy of medicine is just a part of his original system of science, Ki-Hak.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acelluair basement membrane material in the lumen, and 3) cells lacking true nuclear molding and having bland chromatin pattern. The mcrphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

PURPOSE: To evaluate the enhancement patterns revealed by dual-phase CT, and other characteristic features of nodular hepatic involvement of malignant lymphoma, and to determine the usefulness of this imaging modality in the differentiatial diagnosis of hepatic masses. MATERIALS AND METHODS: Seven cases that pathologically confirmed as nodular hepatic involvements of malignant lymphoma among patients who underwent dual-phase CT for the staging or follow-up of malignant lymphoma, and two that confirmed as primary lymphoma among patients who underwent dual-phase CT for differential diagnosis of nodular hepatic masses were evaluated. There were eight cases of non-Hodgkin 's lymphoma (NHL) and one of Hodgkin 's disease(HD). The findings were analysed in terms of the number, size, and contour pattern of the masses, the enhancement pattern seen on dual-phase CT, and whether or not the vascular structure of the mass was normal. RESULTS: Primary lymphomas were present in two patients(single mass, n=1; multiple nodules, n=1) and secondary lymphomas in seven (single mass, n=6; multiple nodules, n=1). The maximum size of main masses was mean 5.1(range, 2-12) cm, and the contor was smooth in three cases, ill-defined in three and lobulated in three. During the early phase, five patients showed homogeneous low attenuation, and heterogeneous enhancement was observed in four. During the late phase, three of the five showed peripheral enhancement and the other two showed the same low attenuation, while two of the four showed central low attenuation, one showed iso attenuation, and one showed heterogeneous enhancement. In four of the patients whose main mass was larger than the mean, vascular shadow passed through the mass (left portal vein, n=2; branches of the right portal vein, n=1; and branches of the hepatic artery, n=1). CONCLUSION: Where dual-phase CT demonstrated nodular hepatic involvement of malignant lymphoma, contrast enhancement varied and so differentiation from other hepatic masses such as metastatic adenocarcinoma and hepatocellular carcinoma was therefore difficult. Homogeneity and a lack of necrosis, even though a mass is large and has a smooth well-defined contour, no capsulation and normal vasculature, may suggest the nodular hepatic involvement of malignant lymphoma.
