BACKGROUND AND OBJECTIVES: It is difficult to correct anterior nasal septal dislocation and subluxation. This study reviewed our surgical technique for correcting septal dislocation and subluxation. SUBJECTS AND METHOD: This retrospective study reviewed the medical records of 20 patients who underwent septal reconstructive suturing of the cartilage to the premaxilla. Acoustic rhinometry, endoscopic pictures, visual analogue scale (VAS) scores, and patient satisfaction were evaluated. RESULTS: The results of acoustic rhinometry showed that there was significant (p<0.05) improvement in the minimum cross-sectional area on both sides of the nasal cavity. The nasal cavity volume was also increased bilaterally, although not significantly on the convex side (convex side, p=0.108; concave side, p=0.007). Thirteen patients had complete correction of the septal deformity on the endoscopic pictures and seven had incomplete correction. The VAS score for nasal obstruction was decreased significantly (p<0.05). Most patients (85%) felt satisfied with the surgery. Only one patient complained about a mild deformity of the external nose. No other major complications were encountered. CONCLUSION: The correction of caudal septal dislocation or subluxation with the excision of excessive septal cartilage and suturing the cartilage to the premaxilla are both successful methods for treating septal deformities.

PURPOSE: Traditionally, the treatement of choice has been a bone grafting procedure to increase the length of bone in case of actual length discrepancy. But, bone grafting procedure has many disadvantages, for example, graft resorption, donor site morbidity, and so on. So, many trials have been performed to avert the use of autogenous bone graft via introducing new materials or methods. And, one of those trials has been realized by the development of a technique inducing bone lengthening by osteotomy (or corticotomy) and slow gradual distraction of the osteotomized segments. This new technique of bone lengthening dates back to the early 20th century. But, the majority of information concerning the biology of new bone formation during bone lengthening and technical details of the procedure were produced by extensive clinical and experimental studies performed by Ilizarov, a Russian surgeon. According to Ilizarov, with adequate blood supply, preservation of periosteum, rigid fixation of the osteotomized segments, and proper rate and rhythm of distraction, intramembranous bone rapidly develops within the distraction gap in the limb lengthening procedure. In the limb lengthening, many orthopedic surgeons try to observe the biologic and clinical principles recommended by Ilizarov. In the oral and maxillofacial region, however, not a few studies must be performed to apply this surgical technique in the clinical cases. Besides, the mechanism of bone formation in the distraction gap is not clear, yet. The purpose of this experiment was to scrutinize seriallly the histological changes in the elongated bone affected by osteodistraction of the mandibular body in an adult canine model. In addition, it was performed to confirm the presence of specific region(s) which was important in the bone formation in the gap through the observation of the expression pattern of osteocalcin and osteonectin with the immunohistochemical examination. MATERIALS AND METHODS: The experimental and control specimens were obtained from seven adult male mongrel dogs weighing over 20kg. The distractors were custom-made linear extraoral devices and bicortical fixation screws were 2.3mm in diameter, 50mm in total length, 15mm in screw length. The distractors were devised to produce a linear gap of 0.75mm between two bony segments every 360.turn of the rotation rod of the device. The mandibular body of the right side of each animal was corticotomized perpendicular to the occlusal plane and then two bony segments were separated completely by careful manipulation of the segments with bone forceps. The left side of each animal was left intact. This side was served as control. At sixth day after osteotomy and fixation of the segments were performed, distraction of the segments was commenced with a rate of 1.1mm/day and a rhythm of two/day for ensuing 7 days. the animals were euthanized at the 16th. 29th, and 44th day after the osteotomy. The bony specimens were decalcified, embedded in paraffin, sectioned 5micrometerthick and stained with H&E. The prepared specimens were examined under the light microscope. And, immunohistochemical examinations using anti-osteocalcin antibody (OC1, Biodesign, USA) and anti-osteonectin antibody Haematologic Technologies Inc., Essex, VT) to locate the expressions of osteocalcin and osteonectin, respectively, were performed. RESULTS: 1. New bone was observed already at the 16th. day after osteotomy. This suggests that new bone formation in osteodistraction was commenced at an early stage of the regenerative process. But, radiologically and microscopically, bony union was not completed in the distraction gap at the 44th. day after osteotomy. Therefore, rigid fixation must be maintained between the bony fragments till the complete bony union is confirmed clinically rather than one month or so after the completion of distraction. 2. Intramembranous bone formation predominated the regenerative process in the distraction gap. Some of the regenerated bone, however, was formed by endochondral ossification. 3. Focal islands of cartilage were observed at all experimental periods. 4. Considering the expression pattern of osteocalcin and osteonectin, new bone formation was considered to be commenced at the region adjacent to the central fibrous zone and therefore this region, especially the periosteum of this region, was important in regeneration of the distraction gap. Focus needs be set on the region adjacent to the CFZ and the role of periosteum in performing further experiments to elucidate the mechanism of bone formation in the distraction gap.

Bisphosphonates (BPs) are a class of agent used to treat patient with osteoporosis or malignant bone metastases. BPs can be categorized into 2 groups: nitrogen-containing and non-nitrogen containing. Nitrogen-containing BPs are considered to have more toxicity. Despite their clinical benefits, bisphosphonate-related osteonecrosis of jaw(BRONJ) is a significant complication to patients receveing these drugs. Since the first description of BRONJ in 2003 by Marx, the number of reports on BRONJ has been rapidly increasing. BRONJ is considered as an emerging problem in oral & maxillofacial surgery. Generally, osteonecrosis in the maxilla is rare, however BRONJ is found both in the maxilla and the mandible. This is an important feature of BRONJ compared to common infectious osteomyelitis of the jaw. Growing number of case reports, suggest that bisphosphonate therapy may cause exposed, necrotic bone. BRONJ has simillar features compared to IORN (infected osteoradionecrosis). BRONJ has meaningful features established through the interestigation on histopathologic and radiographic findings. These features have an impact on treatment plan and prognosis. This presentation contemplates on features of histopathologic and radiographic findings in bisphosphonate-related osteonecrosis of the jaw.

A gastric neuroendocrine carcinoma is very rare, and the histological diagnosis is very difficult. These carcinomas result in a poor prognosis because they are preceded by severe lymphovascular invasion and early metastasis. In particular, it is difficult to distinguish between adenocarcinoma and neuroendocrine carcinoma by endoscopy when no specific symptoms are present (e.g., dyspepsia, nausea). According to published articles in Korea, most cases were diagnosed as adenocarcinoma initially; however, they were confirmed postoperatively as neuroendocrine carcinoma based on a histological examination using immunohistochemical staining. A case of a 55-year-old man, who had an incidental finding of a subepithelial tumor during his health check-up, was recommended for an endoscopic submucosal dissection (ESD). But the patient was lost to follow-up for 4 years. When he was examined again, the size of the tumor had increased from the previous exam. He underwent ESD and was diagnosed with a well-differentiated neuroendocrine carcinoma.

Although most of pseudocysts as one of complications of pancreatitis occur primarily within the pancreas, the extrapancreatic locations of pseudocysts, especially in the liver, are rare events. With advanced technology of imaging studies including abdominal computed tomography, ultrasonography, and magnetic resonance imaging, their frequency seems to be increasing. We report here a case of left intrahepatic pancreatic pseudocyst following acute pancreatitis. Percutaneous puncture revealed a high level of amylase and lipase in the collection, confirming the diagnosis of intrahepatic pseudocyst. Symptomatic intrahepatic pseudocysts can be managed surgically, transcutaneously or endoscopically, and asymptomatic intrahepatic pseudocysts can be treated conservatively. We report this case with a review of literature.

Actinomycosis is a rare chronic suppurative disease caused by actinomyces species, which are normal flora in the oral cavity and gastrointestinal tract, and characterized by formation of sulfur granule. Actinomyces can affect cervicofacial, pulmonary, abdominal and pelvic area. However, abdominal and pelvic inflammations are less frequently observed. Most of abdominal actinomycosis develop after abdominal operation, trauma, inflammatory bowel disease or use of intrauterine devices. The definitive diagnosis was made after histopathological study of the tissues. Treatment is long-term antibiotic therapy. Herein, we report a case of a 69-year-old woman with an unusual form of abdominal actinomycosis after total gastrectomy.

BACKGROUND/AIMS: Clinical manifestations of intestinal yersiniosis include enterocolitis, mesenteric adenitis, and terminal ileitis presenting with fever, right lower quadrant pain, and leukocytosis. According to a previous Korean study in 1997, Yersinia was revealed in two among 15 adult patients with mesenteric adenitis (13%). However, recent reports on the prevalence of Yersinia infection in adult patients are few. The aim of this study was to investigate the prevalence of Yersinia infection in adult patients with acute right lower quadrant pain. METHODS: Adult patients (>18 years) who visited Eulji medical center, due to acute right lower quadrant pain were enrolled prospectively from December 2007 to July 2009. Abdominal CT, stool culture, serologic test for Yersinia, and Widal test were performed. RESULTS: Among 115 patients, 5 patients were excluded due to positive Widal test or salmonella culture. In 110 patients, abdominal CT showed right colitis in 20 (18.2%), terminal ileitis in 16 (14.5%), mesenteric adenitis in 13 (11.8%), acute appendicitis in 10 (9.1%), acute diverticulitis in 7 (6.4%), non specific mucosal edema in 36 (32.7%) and no specific lesion in 8 (7.3%). Two (1.8%) of the 110 patients had antibodies to Yersinia. One patient showed acute enteritis and the other patient was diagnosed with acute appendicitis and underwent appendectomy. No Yersinia species were grown on stool or tissue culture. CONCLUSIONS: Nowadays, among adult Korean patients presenting with acute right lower quadrant pain, there have been few incidences of Yersinia infection.

BACKGROUND: A paradoxical response is defined as the radiological and clinical worsening of a previous lesion or the development of new lesion after initial improvement during theprocess of antituberculous treatment. The related factors for the development of a paradoxical response in patients with tuberculous pleurisy are not certain. METHODS: We selected patients with tuberculous pleurisy who had been treated for more than 4 months. The changes onthe serial chest X-ray findings before and after treatment were reviewed. Paradoxical responses were regarded as any worsening or development of new lesion at least 2 weeks after the initiation of treatment. The baseline clinical characteristics and laboratory findings of the peripheral blood and pleural fluid were compared between the patients with a paradoxical response and the patients without a paradoxical response. RESULTS: Paradoxical responses appeared in sixteen patients (21%) among the 77 patients.It took a mean of 38.6 days after the treatment and the time to resolve the paradoxical response was a mean of 32.1 days. For the patients with a paradoxical response, the median age was younger (30.5 years vs 39.0 years, respectively) and the lymphocytic percentage of white blood cells in the pleural fluid was higher (82.1% vs 69.6%, respectively) than for the patients without a paradoxical response. CONCLUSION: The development of a paradoxical response during the treatment of patients with tuberculous pleurisy was not rare and this was related with the age of the patients and the percentage of lymphocytic white blood cells in the pleural fluid.
