Objectives: The aim of this study is to report the results of extracorporeal fixation in patients with mandibular condylar fractures and compare them with the clinical results of conservative treatment. Materials and Methods: The medical records of 92 patients (73 male [M] : 19 female [F], age 13-69 years, mean 33.1 years) treated for condylar fractures at the Department of Oral and Maxillofacial Surgery in Sun Dental Hospital (Daejeon, Korea) from 2007 to 2012 were reviewed. Patients were divided into three groups: group A (23 patients; M : F=18 : 5, age 21-69 years, mean 32.6 years), treated with extracorporeal fixation; group B (30 patients; M : F=24 : 6, age 16-57 years, mean 21.1 years), treated by conventional open reduction; and group C (39 patients; M : F=31 : 8, age 16-63 years, mean 34.4 years), treated with the conservative method ('closed' reduction). Clinical and radiographic findings were evaluated and analyzed statistically. Results: Occurrence of postoperative condylar resorption correlated with certain locations and types of fracture. In this study, patients in group A (treated with extracorporeal fixation) did not demonstrate significant postoperative complications such as malocclusion, mandibular hypomobility, temporomandibular disorder, or complete resorption of condyle fragments. Conclusion: In superiorly located mandibular condyle fractures, exact reconstruction of condylar structure with the conventional open reduction technique can be difficult due to the limited surgical and visual fields. In such cases, extracorporeal fixation of the condyle using vertical ramus osteotomy may be a better choice of treatment because it results in anatomically accurate reconstruction and low risk of complications.

Gradual attrition is a normal process of aging, but severe attrition causes occlusal disharmony, functional disorder and esthetic problems. The collapse of posterior support may cause attrition of anterior teeth, and loss of occlusal vertical dimension (OVD). And it induces the pathologic change of the TMJ, unaesthetic facial appearance and decreased masticatory function. In this case, 70 year-old male presented with decreased vertical dimension and esthetic problems due to worn dentition. Based on assessment of intraoral findings, diagnostic cast and radiographic examination, full-mouth rehabilitation with increase of OVD was planned. After 10 month follow-up, occlusal stability is maintained and through this procedure, satisfactory outcomes were achieved in esthetic and functional aspects.

Pneumocystis carinii pneumonia(PCP) remains the leading cause of death in patients with AIDS. Although the most common radiographic presentation of PCP is the development of diffuse, bilateral interstitial or alveolar infiltrates in 48 to 86 per cent of AIDS patients, PCP may also present with either a completely normal or only minimally abnormal chest radiograph in 6 to 23 per cent of patients. We experienced two patients with AIDS presenting high fever and chest pain but normal chest radiograph, who had been proved to have PCP by bronchoalveolar lavage and trans-bronchial lung biopsy.

We present a case of an unusual infectious complication of a ruptured mediastinal abscess after endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which led to malignant pleural effusion in a patient with stage IIIA non-small-cell lung cancer. EBUS-TBNA was performed in a 48-year-old previously healthy male, and a mediastinal abscess developed at 4 days post-procedure. Video-assisted thoracoscopic surgery was performed for debridement and drainage, and the intraoperative findings revealed a large volume pleural effusion that was not detected on the initial radiographic evaluation. Malignant cells were unexpectedly detected in the aspirated pleural fluid, which was possibly due to increased pleural permeability and transport of malignant cells originating in a ruptured subcarinal lymph node from the mediastinum to the pleural space. Hence, the patient was confirmed to have squamous cell lung carcinoma with malignant pleural effusion and his TNM staging was changed from stage IIIA to IV.

Pulmonary paragonimiasis continues to be a diagnostically challenging parasitic disease, despite a drastically decreased prevalence in South Korea during the past decade. Pulmonary paragonimiasis is characterized by fever, chest pain, and chronic cough with hemoptysis. Numerous radiographic and computed tomographic findings including the presence of pneumothorax, pleural effusion, and parenchymal lesions such as nodular or infiltrative opacities have been reported. The clinical and radiological manifestations of paragonimiasis can resemble those of lung cancer, tuberculosis or a metastatic malignancy. Furthermore, this disease can mimic lung cancer as seen on $^{18}F$-fluorodeoxyglucose positron emission tomography (FDG-PET). We report a case of pulmonary paragonimiasis in a 48-year old man that presented with a solitary pulmonary nodule and was suspected as a lung cancer based on FDG-PET imaging.

Canine pyometra generally occurs in intact female dogs of more than four years of age. However, in rarely cases, pyometra can occur in young bitches. In the present report, two cases of pyometra in thirteen and eighteen months of age were presented. In both cases, absent of vaginal discharge represented that both patients had closed-cervix pyometra and diagnosis was somewhat complicated. In complete blood count, elevated level of leukocyte with left shift was found in both cases. Serum chemistry analysis showed elevation of alkaline phosphatase in both cases. Additionally, mild elevation of aspartate transferase and total protein were also found in $2^{nd}$ case. Radiographic and ultrasonographic findings show the enlargement of uterus and accumulation of fluid contents inside the uterine lumen. Ovariohysterectomy followed by antibiotics and anti-inflammatory drugs for post-surgery medication was performed for treatment. After a week, both patients fully recovered. To reduce mortality of pyometra in young intact female dogs, radiography or ultrasonography should be indicated immediately in the bitches showing severe infectious inflammation.

An 1.28 kg, male, thirteen years of age, red-eared slider (Trachemys scripta elegans) was presented with one month history of anorexia, decreased mobility, and swelling and erythema of forelimbs. Hyperuricemia and tophaceous gout such as osteolysis at the digit, carpal and metacarpal bones with radiopaque densities around the lesion were detected. Allopurinol (20 mg/kg, PO, once a day) and u/d (Hill's diet) were selected for treatment and other antibiotics or anti-inflammatory drugs were not administered. One month after initial presentation, clinical signs and radiographic findings were improved. According to the medical response, the turtle was presumptively diagnosed as articular gout and allopurinol revealed effective response to the articular gout in turtles.

A 4-year-old, neutered male Shih-tzu dog weighing 5.4 kg was referred due to anorexia and chronic coughing. Based on history, physical examination, laboratory tests, radiographic findings, echocardiography, and bronchoscopic examination, the dog was diagnosed as tracheobronchial foreign body. The foreign body was steamed rice debris, which was removed by bronchoalveolar lavage (BAL) with vacuum suction of bronchoscopy. Bacterial and fungal culture of collected BAL fluid was negative. Baermann test for lungs parasites also was negative. The dog was treated with bronchodilator, antibiotics, anti-inflammatory agent, and mucolytics for 7 days. Appetite increased and coughing sign was clearly improved after removal of foreign body and medical therapy. This case report describes that bronchoscopic techniques are available for the evaluation and management of airway foreign bodies.

Deep circumflex iliac artery (DCIA) flap can be harvested as a composite free flap and is often used to adequately reconstruct wide mandibular defects. However, the harvesting of this DCIA flap can result in severe osseous defect of the donor site causing a morphologic defect in the iliac crest. To reconstruct this defect of the iliac donor site, several innovative techniques using bioactive ceramic spacers, autogenous rib bone, polylactic acid mesh, or titanium plates have been introduced. Nonetheless, these methods have not been widely used due to high cost, secondary donor site morbidity, difficulty of use, and postoperative dissatisfaction. We used two titanium plates to reconstruct the donor iliac site defect at the harvesting time of primary DCIA flap surgery in the 30-year old female with an ameloblastoma in the left mandible. Postoperatively, both iliac sites were relatively balanced and there were few complications. At the 2 years follow-up, there were no specific abnormal radiographic findings and the patient was very satisfied with her esthetic iliac contouring. In our report, we evaluate the effect of two titanium plates on the reconstruction of the iliac donor site in the aspects of esthetics and usefulness. This technique has many advantages, such as reduced cost, simplicity, decreased postoperative pain or discomfort, and improved bilateral balance of both anterior iliac crest contours, especially in young female patients.

Objective : The present study analyzed the risk factors, prevalence and clinical results following revision surgery for adjacent segment degeneration (ASD) in patients who had undergone lumbar fusion. Methods : Over an 8-year period, we performed posterior lumbar fusion in 81 patients. Patients were followed a minimum of 2 years (mean 5.5 years). During that time, 9 patients required revision surgery due to ASD development. Four patients underwent autogenous posterolateral arthrodesis and extended transpedicle screw fixation, 4 patients underwent decompressive laminectomy and interspinous device implantation, and 1 patient underwent simple decompression. Results : Of the 9 of patients with clinical ASD, 33.3% (3 of 9) of patients did not have radiographic ASD on plain radiographs. Following revision surgery, the clinical results were excellent or good in 8 patients (88.9%). Age > 50 years at primary surgery was a significant risk factor for ASD development, while number of fusion levels, initial diagnosis and type of fusion were not. Conclusion : The incidence of ASD development after lumbar surgery was 11.1% (9 of 81) in this study. Age greater than 50 was the statistically significant risk factor for ASD development. Similar successful clinical outcomes were observed after extended fusion with wide decompression or after interspinous device implantation. Given the latter procedure is less invasive, the findings suggest it may be considered a treatment alternative in selected cases but it needs further study.
