This report was a 10year retrospective study on mandible fractures. The study was based on a series of 245 patients who had been treated for mandibular fractures as in-patient at Yongsan Hospital of Medical college of Chung-Ang University during the period of Jan. 1987 to Dec. 1996. The results obtained are as follows; 1. In respect of incidence, the number of fractures was increased to 1990 and then it was decreased. The ratio of Men to Women was 6 : 1. 2. The major etiologic factors were traffic accident(30.2%), fisticuffs(28.6%), falldown(25.3%), accident related to work(7.8%), and sports(6.9%). In recent years, the decreasement of fractures due to traffic accident and the increasement of fractures due to sports was impressive. 3. The age frequency was highst in the third decade(44.9%), and second(%), fourth(%), decade in orders. In the first decade, the cause of fractures was traffic accident and falldown only, and the fractures due to sports were concentrated on second and third decade. 4. The frequent location of mandibular fractures was symphysis(36.1%), left angle(16.4%), right condyle(10.4%), right angle(8.6%), left condyle(8.6%), left body(5.8%), left ramus(4.0%), ramus(3.8%). The number of average fracture site was 1.62 at each patient and the number of average fracture line was 1.91 at each patient. 5. The simple fracture was 43.7%, and the complex fracture was 56.3%, then the open fracture was 35.5%, and the closed fracture was 64.5%. 6. In respect of treatment, the frequency of open reduction was 74.3% and that of closed reduction was 25.7%, but in the condyle, closed reduction(68.0%) was the more frequently using method of treatment than open reduction(32.0%). 7. The patients were treated an average of 3.27 days after injury and the average hospitalization period was 10.07 days. 8. The mandibular 3rd molar was existing in 60.6% of angle fractures.

We report a case of eosinophilic pustular folliculitis in a 6-month-old male infant who had pruritic, tiny, erythematous papulopustules on his scalp and eosinophilia in the peripheral blood. Histopathologic examination revealed an acute follicu1ar and perifollicular inflammatory infiltrate with abundant eosinophils. The patient responded to systemic and topical corticosteroid and dapsone.

BACKGROUND: In congenital heart disease, the lung perfusion through stenosed pulmonary artery is usually decreased. And this decrement of lung perfusion also occurs with diaphragmatic palsy after the operation of congenital heart disease. It is difficult to delineate the amount of lung perfusion in case of combination of pulmonary artery stenosis and diaphragmatic palsy. We examined the change of lung perfusion after the induction of diaphragmatic palsy in rabbits. METHODS: We dissected left phrenic nerves in 20 rabbits to induce left diaphragmatic palsy. The lung perfusion scan was performed with 99mTc-MAA and the movement of diaphragm was examined with fluoroscopy. They were performed as baseline data and on 3rd and 10th day postoperatively. The amount of left lung pefusion before and after diaphragmatic palsy was compared and analysed in 12 rabbits which definitely had diaphragmatic palsy. RESULTS: Weight of the rabbits was 1.65+/-0.26 kg. Left lung perfusion percent was 45.93+/-6.42% before operation and these were 32.48+/-6.09% and 37.62+/-3.39% on the 3rd and 10th postoperative day, respectively. Left lung perfusion was significantly decreased just after diaphragmatic palsy but it was not changed thereafter. The decrement of lung perfusion was not affected by the body weight. The decreased amount of left lung perfusion was reciprocally correlated with the body weight of the rabbits on the postoperative 3rd day but not 10th day. CONCLUSION: Left lung perfusion percent of the rabbits was decreased 7% with the induction of diaphragmatic palsy and the decreased amount was reciprocally correlated with the body weight just after the diaphragmatic palsy was induced.

"Pseudosarcomatous change" occurs when sarcoma-like atypical cell hyperplasia is grossly indistinguishable from malignant tumor. Pseudosarcoma often exists in those areas of the gastrointestinal track where ulcer or erosion commonly takes place. This may indicate atypical granulomatous cell proliferation during a period of healing, as well as benign atypical change in the mesenchyme due to chronic inflammatory reaction. Both the visual appearance and intestinal involvement of tuberculous colitis are variable, and tuberculosis may result in reactive mesenchymal change associated with ulcer or polyp, which is that's induced by chronic inflammation. We report here on a case of a young female pulmonary tuberculosis patient who suffered with a pseudosarcoma of the ascending colon, and this was associated with tuberculous colitis. The patient underwent successful sugical resection. We report on this case, along with a review of the relevant literature.

Cutaneous metastasis from renal cell carcinoma is unusual and have been reported infrequently. We report a case of metastatic renal cell carcinoma in a 33-year-old man who presented with a 3.5X2.0 cm-sized round, brightly red colored nodule on the scalp for 1 month. A skin biopsy revealed the typical clear cell adenocarcinoma with clear cytoplasm and oval hyperchromatic nuclei arranged in glandular pattern consistent with metastatic renal cell carcinoma. In most instances, once cutaneous involvement is manifested the disease is widespread and has a poor prognosis. But, our case presented only a single cutaneous nodule, and workup showed no evidence of further metastasis for 1 year.

Keratocystic odontogenic tumors (KCOT) - previously termed odontogenic keratocysts (OKC) - are characterized by aggressive behavior and a high rate of recurrence. Histopathologically, the basal layer of KCOT shows a higher cell proliferation rate and increased expression of anti-apoptosis genes. Clinically, KCOT is frequently involved in the mandibular posterior region but is not common in the posterior maxilla. However, it should be noted that due to its expansive characteristics, KCOT involved near the maxillary sinus could easily expand to an enormous size and occupy the entire maxilla. To achieve total excision of these expanded cystic tumors in the maxilla, a more aggressive approach would be needed. In this report, we describe two cases of expansile KCOT involving the entire unilateral maxilla and maxillary sinus; they were completely excised using the Weber-Ferguson approach, showing no evidence of recurrence during the follow-up period of more than two years. In immunohistochemical analyses of the tumor specimens, p53 and p63 showed strong expression, and B-cell lymphoma 2 (BCL2) and MKI67 (Ki-67) showed moderate or weak expression, however, detection of BCL2-associated X protein (BAX) was almost negative. These data indicate that expansile KCOT possesses increased anti-apoptotic activity and cell proliferation rate but decreased apoptosis. These properties of KCOT may contribute to tumor enlargement, aggressive behavior, and high recurrence rate.

PURPOSE: Since most terminally ill cancer patients die of multiple organ failure, plasma endotoxin concentration levels may be used to predict the life expectancy. This study was performed to evaluate the clinical significance of endotoxin level in plasma as a prognostic factor for survival in patients with terminal cancer. METHODS: This study was conducted with 56 terminally ill cancer patients, above 20 years old, from April 2009 through October 2009. Demographic characteristics, Karnofsky performance status, and survival time were evaluated. We analyzed blood levels of white blood cell hemoglobin, hematocrit, aspartate aminotransferase, alanine aminotransferase, c-reactive protein, total bilirubin and endotoxin in each patient. RESULTS: We considered following variable for univariate analysis: plasma endotoxin level, sex, age, WBC, hemoglobin, hematocrit, AST, ALT, total bilirubin, CRP and severity of pain. Univariate analysis did not show a significant association between plasma endotoxin level and survival time. However, in a multivariate analysis with factors that were found to be significantly associated with survival sex, WBC count and total bilirubin level in univariate analysis, high levels of plasma endotoxin and short survival time were significantly related. CONCLUSION: Plasma endotoxin level could be used as a prognostic factor to predict the life expectancy of terminally ill cancer patients.

Signet ring cell carcinoma has been previously described in many organs, most frequently in the stomach, and rarely in the colon, rectum, gallbladder, pancreas, breast, nadsal cavity, prostate, urinary bladder and ureter. Signet ring cell carcinomas in the lung, especially, when examined by small biopsies, are generally believed to be metastatic. This case was diagnosed by bronchoscopic biopsy. We also examined various organs by noninvasive method, including UGI series, barium enema and abdomen CT scarf, but all studies were nomal. Patient received cisplatin and etoposide combination chemotherapy followed by local radiotherapy ai a primary non-small cell lung cancer. Patient died of his disease 6 months after diagnosis. Now we report a case of primary signet ring cell carcinoma of the lung.
