ABSTRACT
Scedosporium apiospermum, the anamorph of Pseudallescheria boydii, is a ubiquitous saprophytic fungus. S. apiospermum can cause life-threatening infections usually in immunocompromised patients or after near-drowning incidents. Here, we report the first case of disseminated infection caused by S. apiospermum after near-drowning in Korea. A 44-year-old healthy man developed aspiration pneumonia, followed by multiple brain abscesses, and endopthalmitis, after a near-drowning incident in a septic tank. S. apiospermum infection was diagnosed on the 33rd day after the incident had occurred. The patient died from the progressive renal failure 255 days after incident, although he had been treated with voriconazole.

lcaligenes xylosoxidans is a catalase and oxidase positive, motile, nonfermentative and gram-negative rod bacterium. A. xylosoxidans infection is a rare cause of pulmonary infection and little information concerning treatment is available. The majority of patients that develop A. xylosoxidans infection belong to a high-risk group due to an immunocompromised condition or due to pulmonary cystic fibrosis. We report two rare cases of immunocompentent patients that developed a pulmonary infection due to A. xylosoxidans. A 77-year-old man was admitted with a lung abscess. The patient denied having any prior medical illness. A culture of bronchial washing fluid showed the presence of A. xylosoxidans. Despite appropriate antibiotic treatment, the patient died from acute respiratory distress syndrome (ARDS). Another patient, a 61-year-old man without an underlying disease, was admitted with empyema. Under the condition of a closed thoracostomy, a high fever persisted and the empyema was also aggravated. A. xylosoxidans was detected from a culture of pleural fluid. Susceptible antibiotic treatment was provided and surgical intervention was performed. We report these cases with a review of the literature.

The lipoma is the neoplasm of mesenchymal origin. Although most lipomas occur on the trunk and the proximal portion of the extremities, lipomas of the oral and maxillofacial regions are relatively rare, approximately 13% of all cases. Lipomas have been found in all age, but usually found between 40 and 60 years of age. Clinically the lipoma is a painless, slowly growing, nearly always benign soft mass. The treatment of choice is a surgical excision, and the recurrence is rare. But the infiltrating lipoma originated from muscle has high recurrence rate. It has ill-defined border and little or no evidence of encapsulation. Histologically there is a consistent infiltration with dissociation of the surrounding muscle fiber. The infiltrating lipoma should be excised with surrounding normal muscle and tissue to prevent the recurrence. This case was a 57-year-old female with a painless swelling of the right cervical and parotid areas which was diagnosed as large infiltrating lipoma by clinical examination and radiographic findings. The patient was treated by surgical excision and showed good functional and esthetic results. Histologically the tumor was diagnosed as infiltrating lipoma with no evidence of malignancy.

The treatment plan for orthognathic surgery must be based on accurate predictions, and this can be produced the most esthetic, functional and stable results. The purpose of this study was aimed to evaluate the amount and interrelationship of the gonial angle and the mandibular width change after the mandibular setback surgery in the mandibular prognathic patients. Twenty patients were selected who received orthognathic surgery after presurgical orthodontic treatment. The patients with skeletal and dental Class III malocclusion were operated upon with bilateral sagittal split ramus osteotomy and mandibular setback. The lateral and posteroanterior cephalometric radiographs were taken preoperatively, postoperative 1 day and 12 months later after the orthognathic surgery, and then the gonial angle and mandibular width were measured. The computerized statistical analysis was carried out with SPSS/PC program. The gonial angle at postoperative 1 day was decreased about 5.3 degrees than preoperative value and the gonial angle at postoperative 12 months was increased about 1.4 degrees than postoperative 1 day. So the gonial angle at postoperative 12 months was decreased about 3.9 degrees than preoperative value. The mean preoperative gonial angle was 125.35 degrees +/-7.36, showing significantly high value than normal and mean gonial angle at postoperative 12 months was 121.45 degrees +/-6.81, showing value near to normal. The mandibular width at postoperative 1 day was decreased about 1.1 mm than preoperative value and the mandibular width at postoperative 12 months was more decreased about 1.7 mm than postoperative 1 day. So the mandibular width at postoperative 12 months was decreased about 2.8 mm than preoperative value. These results indicate that sagittal split ramus osteotomy in mandibular prognathic patients with high gonial angle is effective to improvement of gonial angle. It is considered to be helpful for maintenance of postoperative stable gonial angle area that detailed postoperative care and follow-up.

Oral and maxillofacial infections are most commonly odontogenic in origin. The present study was implemented for patients with oral and maxillofacial infections in order to determine what differences were present in cultured bacteria, depending upon the different types of infection. For the present study, the epidemiological characteristics, the state of infection, and the results of the pus culture and antibiotic susceptibility tests were analyzed for the 159 cases where pus culture tests were performed. The patients were treated at the Oral and Maxillofacial Surgical Department of Chonnam National University Hospital during an 18-months period from March 2003 to August 2004. Among the total 159 pus culture specimens, bacteria were cultured in 111 cases (69.8%). In the 111 pus culture specimens, Streptococcus species, Neisseria species, and Staphylococcus species were cultured from 69 cases (51.1%), 21 cases (15.6%), and 15 cases (11.1%), respectively and were determined to be bacterial strains the predominant bacteria responsible for oral and maxillofacial infectious diseases. Twenty four cases (15.1%) among the 159 specimens showed mixed infections. The mostly isolated bacteria from each of the space abscess, dentoalveolar abscess, inflammatory cyst, and pericoronitis cases were the Viridans streptococci. There was little relevance between the type of infection and the type of cultured bacteria. Antibiotic susceptibility tests showed a high level of susceptibility to teicoplanin(100%), vancomycin(100%), chloramphenicol(96.4%), ofloxacin(88.3%), imipenem(83.3%), erythromycin(82.5%) and a low susceptibility to cefazolin(40.0%), oxacillin(44.7%), ampicillin(49.4%), penicillin(51.1%). These results indicate that there was no significant difference among the cultured bacteria depending on the type of infections and their susceptibility to cephalosporin and penicillin G was low.

Generally we use the preauricular incision to access and remove the parotid gland tumor. But the preauricular approach has some complications such as damage of facial nerve and sensory nerve, Frey's syndrome, and postoperative scar. Especially, the postoperative scar can often cause an unesthetic result and mental stress in young patients. Therefore, if we avoid preauricular incision to be performed outside of tragus, the postoperative scar would be hardly remarkable, and patients would be satisfied cosmetically. We performed surgical excision using a modified endaural and neck approach in a 21-year-old female with a pleomorphic adenoma and 15-year-old male with a neurofibroma occured in the parotid gland. A new, modified endaural and neck approach is a combined method of the modified endaural incision by Starck et al and Gutierrez's neck extension. We obtained an adequate access and the cosmetically acceptable postsurgical scar. The postoperative scars were hidden in the external ear and the hairline. Moreover, except the neck dissection can this approach be applied to the surgery of temporomandibular joint as well as the parotid gland tumor.

PURPOSE: The aim of this study was to evaluate the skeletal and dentoalveolar dimensional changes following surgically-assisted rapid maxillary expansion (SARME). PATIENTS & METHODS: Thirteen adults who had been treated by SARME for transverse maxillary deficiency from May 2000 to December 2003 were evaluated. The SARME procedure was the subtotal Le Fort I osteotomy combined with pterygomaxillary separation and anterior midpalatal osteotomy. Dental study casts and posteroanterior cephalometric radiographs were taken before operation, after removal of expansion device, and follow up period. Nasal cavity width, skeletal and dentoalveolar parameters were measured pre- and post-operatively. RESULTS: 1. Mean nasal cavity width was increased 12%(0~21%) of total expansion after retention. 2. Mean maxillary interdental width was increased 70%(47~99%), 95%(84~115%), and 77%(57~94%) of total expansion in the canine, the first premolar, and the first molar region, respectively after retention. 3. Mean maxillary alveolar bone width was increased 66%(42~84%), 74%(42~94%), and 57%(31~78%) of total expansion in the canine, the first premolar, and the first molar region, respectively after retention. 4. Mean palatal vault depth was decreased 1.3 mm (0.5~2.0 mm) after retention. 5. Mean interdental and alveolar bone width of the mandibular canine and intermolar width of mandible were slight increased as maxilla was expanded after retention. 6. There were statistical differences between preoperative and postoperative values of nasal cavity, all maxillary interdental and interalveolar widths, palatal vault depth, mandibular interdental and interalveolar width of canine(paired t-test, p <0.05). 7. The maxillary interdental and alveolar bone width were decreased approximately 25% of total expansion by relapse at follow up period. CONCLUSION: In conclusion, most amounts of maxillary interdental expansions were acquired with the expansion of the maxilla by SARME. For preventing the relapse, approximately 25% of the overexpansion was needed.

Anticonvulsant hypersensitivity syndrome is a potentially fatal drug reaction with cutaneous and systemic reactions to the arene oxide-producing anticonvulsants: phenytoin, carbamazepine, and phenobarbital. In most cases, the hallmark features of fever, rash, and lymphadenopathy are accompanied by multiorgan-system abnormalities. We experienced a 41-year-old man with a carbamazepine-induced reaction, presenting with fever, rash, eosinophilia, hepatitis, and eosinophilic pneumonia. Because symptoms persisted in spite of discontinuation of carbamazepine, we administered a systemic steroid. After use of the steroid, symptoms were relieved and liver and pulmonary functions improved gradually.
