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.

PURPOSE: The objectives of this study were to estimate myocardial functions in patients with chronic renal failure by pulsed Doppler echocardiography, and investigate correlation between Doppler and disease parameters. METHODS: We studied 13 patients with chronic renal failure whose creatinine clearance rate less than 25ml/min. Using pulsed Doppler echocardiography with curve following method, we measured peak velocity, mean velocity, velocity-time integral and peak acceleration of aortic and pulmonic flow velocity curves, and peak velocity, mean velocity, area of rapid filling wave in early relaxation phase(E wave) and filling wave by atrial contraction in late relaxation phase(A wave) and A/E ratios of the peak velocity and area. And we compared these parameters with those of the normal controls, and then those with early chronic renal failure(less than 6 months of disease duration) and those with late chronic renal failure(more than 6 months of disease duration). RESULTS: In patients with early chronic renal failure, peak velocity, flow time and area of E wave of the mitral flow velocity curves were significantly decreased, and those of A wave were markedly increased and resulted in marked increase in A/E ratios of the peak velocity and area compared with those of the normal controls. In patients with late chronic renal failure, mitral A/E ratio of the peak velocity continued to be increased, and peak velocity, velocity-time integral and peak acceleration of the aortic flow velocity curves were significantly decreased but pulmonary velocity- time integral was increased markedly compared with those of the normal controls. CONCLUSIONS: Significant increase of mitral A/E ratio in patients with early chronic renal failure and appearance of significant change in aortic flow velocity curves in patients with late chronic renal failure suggest that abnormalities of myocardial relaxation seem to be present in early phase of the chronic renal failure and continued into late phase but abnormalities of myocardial contraction to appear on late phase of the chronic renal failure.

BACKGROUND: To decide the optimal antibiotics and application of chest tube, examination of pleural fluid is fundamental in the management of empyema. Some criteria for drainage of pleural fluid have been recommended but some controversies have been suggested. Recently, newer radiologic methods including ultrasound and computed tomography scanning, have been applied to the diagnosis and management of pleural effusions. We undertook a retrospective analysis of 30 patients with pleural effusion who had CT scans of the chest in order to apply the criteria of Light et at retrospectively to patients with loculation and to correlate the radiologic appearance of pleural effusions with pleural fluid chemistry. METHOD: We analyzed the records of 30 out of 147 patients with pleural effusion undergoing chest CT scans. RESULTS: 1) Six of the pleural fluid cultures yielded gram negative organisms and three anaerobic bacterias and one Staphylococcus aureus and one non-hemolytic Streptococci. No organism was cultured in nineteen cases(63.0%). 2) The reasons for taking chest CT scans were to rule out malignancy or parenchymal lung disease(46.7%), Poor response to antibiotics(40.0%), hard to aspirate pleural fluid(10.0%) and to decide the site for chest tube insertion(3.3%). 3) There was no significant correlations between ATS stages and loculation but there was a tendency to Inoculate in stage III. 4) There was a significant inverse relationship between the level of pH and loculation(P<0.05) but there appeared to be no relationship between pleural fluid, LDH, glucose, protein, loculation and pleural thickening. 5) In 12 out of 30, therapeutic measures were changed according to the chest CT scan findings. CONCLUSION: We were unable to identify any correlations between the plerual fluid chemistry, ATS stages and loculations except pH, and we suggest that tube thoracotomy should be individualized according to the clinical judgement arid serial observation. All patients with empyema do not need a chest CT scan but a CT scan can provide determination of loculation, guiding and assessing therapy which should decrease morbidity and hospital stay.

PURPOSE: Acute appendicitis is one of the most common diseases requiring surgical treatment. Delayed diagnosis, which causes complications like perforation of the appendix, abscess formation, or misdiagnosis, leads to unnecessary surgery. Many scoring systems have been suggested for the diagnosis of acute appendicitis. This study aims to evaluate the clinical value of previous scoring systems. METHODS: This study was conducted with a total of 270 patients who had visited the National Police Hospital (NPH) Emergency Room for acute abdominal symptoms from January to June 2008. The Alvarado and the Ohmann scores were applied retrospectively based on the patients' records. We found 3 criteria which were relatively objective and clinically meaningful; then, we designed a new 10 points scoring system. RESULTS: The sensitivity and the specificity of the Alvarado scoring system were 83.23% and 64.42%, respectively, whereas those of the Ohmann scoring system were 74.85% and 66.35%, respectively. The sensitivity and the specificity of the NPH scoring system were found to be 78.4% and 68.9%, respectively. The Ohmann scoring system showed a little lower sensitivity, and the NPH scoring system showed a little higher specificity, but the differences were not statistically significant. CONCLUSION: Our study indicates that the scoring systems considered are not useful diagnostic methods for primary screening and diagnosis of acute appendicitis.
