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.

The results with management of urethral stricture are disappointing, with a high rate of early and late recurrence. Recently, the success of internal urethrotomy has made us question the role of open urethroplasty in the management of urethral strictures. Thus a clinical evaluation was made on 26 pediatric patients with urethral stricture in the Department of Urology, National Medical Center, during the period from Sep. 1978 to Aug. 1992. The stricture was incomplete in 15 cases and complete in 11 cases. The length of stricture was less than l cm in 17 cases, 1 to 2 cm in 3 cases, more than 2cm in 3 cases and multiple stricture in 3 cases. The treatment modality of incomplete urethral stricture was internal urethrotomy in 12 cases and urethroplasty in 3 cases regardless of length. Incomplete urethral stricture, internal urethrotomy was carried out in 8 cases with less than 1 cm long stricture and urethroplasty in 3 cases regardless of length. But all complete urethral stricture was carried out urethroplasty initially. The overall out come in incomplete urethral stricture, average urine flow rate ranged from 8.5ml/sec to 11.4ml/sec and incomplete urethral stricture, average urine flow rate ranged from 7.0 ml/sec to 20 ml/sec. We think that visual urethrotomy is a valuable initial method, when stricture is incomplete and urethroplasty is a valuable initial method, when stricture is complete.

Authors reviewed the clinical features and diagnostic approaches in 70 patients of cysticercosis who had been diagnosed at Seoul National University Hospital from 1978 to 1982. The ages of the 70 patients ranged from 4 to 65 years at the time of the diagnosis (mean age 36.9years) with 62.9 percent between the age 20 and 50 years. Male were more frequently involved than female (2:1). Forty-seven patients (67.1%) presented with neurological symptoms and signs, among which epileptic seizures (66%) was the most common one. Subcutaneous nodules were observed in 36 patients (50.1%) and 24 patients of them had no abnomal clinical findings other than subcutaneous nodules. Computed tomography (CT), employed in 46 patients, showed multiple low densties in 31 patients (67.4%).

Shy-Drager syndrome is a multisystem degenerative disorder of the central nervous system in which progressive autonomic failure such as orthostatic hypotension, urinary or fecal incontinence, impotence and anhidrosis is a main feature. The nonautonomic neurological abnormalities include parkinsonia, cerebellar and pyramidal signs. In 1984 we met 3 such cases at Seoul National University Hospital and present them here with a brief review of literatures.
