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.

In general, the skeletal class III has the characteristics of mandibular overgrowth with a normal maxillary growth or maxillary undergrowth with a normal mandibular growth And clinical and radiographic evaluations of the patient are needed. However, the treatment plan is not dependent on these evaluations alone, because patient's general condition and hope for aesthetics varies. The aim of this report is to consider the treatment of a medically compromised patient with an anterior open bite and skeletal class III, which showed a severe mandibular overgrowth. In 2003, a 17-year-old boy with epilepsy, mental retardation presented at our clinic complaining of concave profile. A clinical examination showed severe mandibular prognathism with an anterior open bite. The radiographic examination revealed a short cranial base, a moderate maxillary overgrowth, severe mandibular overgrowth and skeletal open bite tendency. In 2004, he was verified to have no potential of growth by hand-and-wrist radiographs and an endocrine examination. He completed the preoperative orthodontic treatment and orthognathic surgery (sagittal split ramus osteotomy, genioplasty). He was evaluated on the first visit, the preoperative period and the postoperative period with a clinical and radiographic examination. At the first visit, the patient showed moderate overgrowth of the maxilla, severe overgrowth of the mandible, and a subsequential skeletal open bite. After the preoperative orthodontic treatment (preoperative period), the patient showed the same skeletal problem as before and a decompensated dentition for orthognathic surgery. After orthognathic surgery, his profile had improved, but he had still a skeletal openbite tendency because the maxillary orthognathic surgery was not performed. Severe mandibular prognathism with a maxillary overgrowth and anterior open bite should be treated by bimaxillary orthognathic surgery. However, one-jaw orthognathic surgery on the remaining the skeletal open bite tendency was performed for his medical problem and facial esthetics. This subsequential open bite should be resolved with a postoperative orthodontic treatment.

The ultraviolet radiation (UVR) is known to be a potent modulator of many host immune functions and the exposure of experimental animals to the inflammatory effects of UVR induces depressions in their ability to initiate and effectuate various types of cellular immune responses. In this study, the effects of UV-B (280 320 nm) radiation on resistance to a facultative intracellular bacterium, Listeria monocytogenes (LM), were examined at the cellular level. The numbers of cultivable LM recovered from the spleens of UV-B-irradiated mice were decreased at 2 days postinfection compared with those of untreated control mice. However, the acquired immunity, developed 7 days after immunization with streptomycin (SM)-sensitive LM, in either UV-irradiated, LPS- or IL-1-pretreated mice was less stronger than that developed in untreated, control mice. To elucidate the possible mechanisms underlying the observation that UVR did increase innate immunity but decreased acquired immunity of mice to the infection with LM, the effects of UVR of mice on the production of IFN-r by activated splenocytes and TNF-a by peritoneal macrophages were assessed. Activated splenocytes from UV-irradiated mice exhibited a reduced capacity to produce IFN-r and cultured peritoneal macrophages produced more TNF-a in the presence of LPS during 24 hours after UV radiation. Though TNF-r activity was not detected in the sera of LM-infected mice, intravenous LPS injection induced TNF-r production and UVR decreased TNF activity in sera obtained from LM-infected mice with LPS induction 9 days after irradiation. Although Ia-negative macrophages were predominant in the peritoneal macrophages from untreated control mice, the infection of mice with LM caused a marked increase in Ia expression on peritoneal macrophages. However, UVR resulted in decreased expression of Ia molecule on the peritoneal macrophages during the LM infection. These findings suggest that the dual effects of UVR on the innate and acquired immunity of mice to the LM infection may be associated with altered capacities of splenocytes and peritoneal macrophages of the mice to produce cytokines, in addition to decrease of la molecule expression on the macrophages.

Despite recent advances in nutritional support, patient monitoring, and surgical intensive care, as well as some improvement in surgical techniques, post-operative fistulas have been regarded as one of the most serious complications in abdominal surgery. The present study was undertaken to evaluate the effectiveness of treatment with total parenteral nutrition (TPN) alone (group A, n=26) or with TPN combined with octreotide, a long-acting analog of somatostatin (group B, n=20) in post-operative enterocutaneous fistulas. In group A, we treated 2 biliary, 10 pancreatic and 14 intestinal cutaneous fistulas with total parenteral nutrition. In group B, we treated 6 biliary, 8 pancreatic and 6 intestinal cutaneous fistulas with octreotide. The results obtained from the analysis are as follows: 1) The spontaneous closure of the fistulas was 69.2% in group A and 75.0% in group B. 2) The mean interval of time to achieve the healing of the fistula was 30.44 days in group A and 14.53 days in group B. 3) The mean interval of time to achieve a fistula output reduction of 50% was 6.44 days in group A and 2.44 days in group B. 4) In patients with low-output fistulas, the spontaneous closure of the fistula was 81.8% in group A and 80.0% in group B. In patients with high-output fistulas, the spontaneous closure of the fistula was 60.0% in group A and 73.3% in group B. 5) In patients with low albumin (< 3.0 g/dl), the spontaneous closure of the fistula was 54.5% in group A and 50.0% in group B. In patients with high albumin (> or = 3.0 g/dl), the spontaneous closure of the fistula was 80.0% in group A and 85.7% in group B. 6) In patients with an abdominal abscess, the spontaneous closure of the fistula was 40.0% in group A and 40.0% in group B. In patients without an abdominal abscess, the spontaneous closure of the fistula was 87.5% in group A and 86.7% in group B. 7) As compared with TPN, the spontaneous closure of the fistulas treated with octreotide was increased in the gastroduodenum and the external biliary system, was similar in the small bowel and the pancreas, but was decreased in the colon. We conclude that octreotide is a useful therapeutic complement in the conservative treatment of selected patients with post-operative cutaneous fistulas, especially fistulas in the external biliary system and the gastroduodenum.

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.

Menetrier's disease is a rare disease characterized by the presence of large rugal folds involving part or all of the stomach. Patients with hypertrophic gastropathy often have distressing abdominal symptoms, weight loss and edema due to gastric protein loss. The 48-year-old male patient was admitted to the Hangang Sacred Heart Hospital with cheif complaints of indigestion and epigastric pain. The diagnosis of Menetriers disease is established by radiologic, endoscopic, and pathologic examination. He was treated with soft diet, antacid, H2- receptor antagonist, and IV albumin. We report a case of Menetriers disease with brief review of literatures.

Actinomycosis still poses a problem for correct clinical and radiologic diagnosis. We retrospectively analyzed CT findings in 7 patients with pathologically proven abdominal actinomycosis. Involved areas were the pelvis (n=3), greater omentum (n=2), liver (n=1), and kidney (n=1). CT confirmed the infiltrative nature of the disease with a tendency to invade across tissue plane and boundary. Five of seven cases were predominantly solid mass (pseudotumor) with focal low-attenuation areas while two were predominantly cystic mass with thickened wall. Contrast-enhanced CT showed dense, inhomogeneous contrast enhancement in the wall and/ or solid components of the masses in five. Minimal lymphadenopathy was noted in one case. CT is useful in demonstrating the extent and characteristics of this disease. Despite nonspecific findings, actinomycosis should be included in the differential consideration when CT shows an infiltrative mass with unusual aggressiveness and dense inhomogeneous contrast enhancement in patients with fever, leukocytosis, or long-term use of intrauterine contraceptive devices.

To determine the incidence, clinical characteristics and coronary angiographic findings of postinfarction angina, clinical course and coronary angiogram were studied in 45 patients with acute myocardial infarction. During a mean follow-up period of 12 weeks, 17 patients(37.8%) developed angina. Of 5 patients with postinfarction angina within 1 week of infarction, 2 patients died during hospitalization, whereas all 12 patients with postinfarction angina which occured more than 1 week after acute myocardial infarction were discharge alive. The frequency of stenosis over 90% and multivessel disease by coronary angiography were 51.7% and 64.7% respectively in patients with postinfarction angina, and 25%, 28.5% respectively in patients without postinfarction angina.
