This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malunioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort 1 osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

This is a report of 2-cases of mandibular prognathism corrected by Intraoral oblique splitting osteotomy of mandibular rami. The Intraoral oblique splitting osteotomy is a modification of sagittal split osteotomy of ramus and it is documented by Yoshida, on 1985. By this method, authors obtained the following results. 1. The patients' esthetic, psychological and functional problems were dissolved by setback of mandibular prognathism. 2. The postoperative infection splitted bone segments fracture, paresthesia of the face and T.M.J. dysfunction were not appeared. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. The patients could open their mouths in normal range after a week of intermaxillary fixation removal. 4. The soft tissue changes of lower lip and chin were about 1:1 to the hard tissue changes. 5. During intermaxillary fixation period and postoperative orthodontic treatment, slight relapse was observed. Now, the patients are under postoperative orthodontic treatment.

PURPOSE: To compare the usefulness of gadolinium-enhanced excretory MR urography using breath-hold three-dimensional fast imaging with steady state precession (3-D FISP) with conventional MR urography using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence in the evaluation of obstructive uropathy. MATERIALS AND METHODS: Twenty-three patients in whom ultrasonography (US) and/or intravenous urography(IVU) revealed signs of urinary obstruction were enrolled in this study. Fifteen were men and eight were women, and their mean age was 54 (range, 21 -80) years. All MR images were obtained using a 1.5-T MR unit. MR urography using the HASTE technique (MRU) and gadolinium-enhanced excretory MR urography using the 3D-FISP technique were performed, and in all cases, reconstructions involved maximum intensity projection. For contrast-enhanced MR urography (CEMRU), images were obtained 3, 5, 20, and 30 minutes after the administration of intravenous contrast media, and for selected cases, additional images were obtained until 24 hours after contrast media injection. For qualitative analysis, two experienced radiologists compared CEMRU and MRU in terms of their diagnostic value as regards the level and cause of urinary obstruction, and morphologic accuracy. In addition, signal to noise ratio (SNR) and contrast to noise ratio (CNR) of the urinary tract at each anatomic level were quantitatively analysed. RESULTS: Quantitative analysis showed that in terms of SNR and CNR of the urinary tract at the level of the mid and distal ureter, CEMRU using 3-D FISP was better than MRU using HASTE (p<0.05). Qualitative analysis indicated that for the depiction of the whole length of normal ureter, and detection of the level of obstruction, anatomic anomalies and intrinsic tumors, 3-D FISP was superior to HASTE. There was, however, no difference between these two modalities in the diagnosis of ureteral stone and the degree of hydronephrosis. In addition, 3-D FISP was better than HASTE for the assessment of filling defect, but the difference was not statistically significant. CONCLUSION: Breath hold 3-D FISP is a very valuable tool in the evaluation of obstructive uropathy. It not only depicts very clearly the anatomy of the urinary tract system, but also provides qualitative information on renal function. We believe that CEMRU using 3-D FISP is a valuable diagnostic approach which can be added to those already available for the workup of obstructive uropathy.

STATEMENT OF PROBLEM: Metal-ceramic restorations have been used extensively by dental clinicians for nearly 40 years. Strength an functional ability of metal-ceramic restorations are proved to be satisfying, However esthetics and biocompatibility of metal alloy which is used in metal-ceramic restoration is not ideal. Using pure gold as an alternative, have advantage of esthetics, biocompatibility over conventional metal alloy. But there had been little article which studied on the color effect of pure gold on final porcelain color. PURPOSE: The purpose of this study was to spectrophotometrically evaluate the difference between color of metal alloy(Au-Pt, Ni-Cr) and pure gold, during color masking procedure with opaque porcelain and to analyze the differences. MATERIAL AND METHODS: Three types of metal-base metal(Ni-Cr), high gold alloy(Au-Pt), pure gold(GES)-specimen were fabricated 1cm in diameter. Four steps were established-after finishing, after pre-coditioning, after application of first opaque porcelain(0.08mm in thickness), after application of second opaque porcelain(0.15mm in thickness)- and tested color with spectrophotometer every each steps and analyzed with CIEL* a* b* color order system. One-Way ANOVA test was used to find out if there were significant differences between groups tested and Shaffe multiple comparison was used to identify where the differences were. RESULTS: 1. After finishing and pre-conditioning, pure gold(GES) group showed most high values in L*, a*, b*. 2. After application of first opaque porcelain(0.08mm in thickness), after appllication of second opaque porcelain(0.15mm in thickness), pure gold(GES) group showed the least difference in L*, a*, b* values and the lowest .E value(.E=0.63). 3. After application of first opaque porcelain and after application of second opaque porcelain differences that were significant (P< 0.05) between groups were found only in a values. 4. Base metal alloy group showed the lowest a value in test after application of first opaque porcelain and the highest value in test after application of first opaque porcelain. CONCLUSION: Pure gold group and high gold group showed higher a values than base metal group when tested after 0.08mm thickness of opaque porcelain was applied and pure gold group showed much similar L*, a*, b* values between 0.08mm thickness and 0.15mm thickness of opaque porcelain. This meant that pure gold was more easily masked by opaque porcelain than the other two groups.

PURPOSE: Among the cell adhesion molecules, alpha-catenin and E-cadherin play an important part in maintaining normal cell structure. The change in expression of cell adhesion molecules affects the invasion and metastasis of a tumor and the prognosis for patients. In this study, we evaluated the relationship between the expression of cell adhesion molecules and the histopathologic characteristics of stage III colon cancer. METHODS: The relationship between the immunohistochemical expression of cell adhesion molecules and tumor progression were statistically analyzed in 40 patients with stage III colon cancer. RESULTS: There were no statistically significant correlations between loss of membranous alpha-catenin and E-cadherin expressions and such variables as histologic differentiation and lymph node disease based on the criteria of the American Joint Committee on Cancer (AJCC). A significant correlation, however, existed between depth of mural invasion and loss of expressions of both alpha-catenin and E-cadherin (P=0.001 and P=0.002, respectively). Expressions of both alpha-catenin and E-cadherin were also significantly decreased in patients showing liver metastases during follow-up (P=0.019 and P=0.015, respectively). CONCLUSION: Immunohistochemical analyses of alpha-catenin and E-cadherin expressions may be available as predictors for distant metastasis, especially in stage III colon cancer. Such analyses may also help to identify appropriate therapeutic strategies and the need for intensive follow-up in patients with stage III colon cancer.

Hematoma of gastric wall is very rare, and occasionally associated with coagulopathy, trauma, peptic ulcer disease, and therapeutic endoscopy. Ischemic gastric necrosis is also rare because of the abundant anastomotic supply to the stomach, and it is usually associated with surgery and disruption of the major vessels. Endoscopic submucosal injection of hypertonic saline-epinephrine (HS-E) is a safe, cost-effective, and widely used therapy for hemostasis but it may cause tissue necrosis and perforation. We describe a case of gastric wall hematoma with oozing bleeding after endoscopic gastric mucosa biopsy in 71-year old woman with chronic renal failure and angina pectoris undergoing anti-platelet medication. We injected a small dose of HS-E (7ml) for controlling oozing bleeding. Two days later, endoscopy showed huge ulcer with necrotic tissue at the site of previously hematoma. Therefore we should pay particular attention for hematoma and mucosal necrosis when performing endoscopic procedure in a patients with high bleeding and atherosclerotic risk.

Idiopathic myelofibrosis is characterized by replacement of the bone marrow with fibrous tissue and the development of extramedullary hematopoiesis. The latter involves mainly the spleen and liver but also occurs in lymph nodes, kidneys, retroperitoneal fat, and more rarely, the skin. We report a 48-year-old male with idiopathic myelofibrosis who was admitted due to numerous papules and nodules on his trunk. The skin lesions were histologically defined as cutaneous extramedullary hematopoiesis.

The number of persons with HIV infection in Korea have increased steadily, total number of HIV infection in Korea were 478 on August, 1995. To investigate the clinicoimmunologic manifestation of AIDS in Korea, we reviewed complete blood counts (CBC), CD4 counts, serum beta2-microglobulin level, opportunistic infections and cause of death for 19 AIDS patients who had been admitted or visited at Pusan national university hospital during the period of January, 1990 to August, 1995. 1) The predominant mode of HIV transmission was heterosexual contact(18), other modes of transmission were homosexual contact(1). Clues of diagnosis of HIV infection were routine occupational health examination(14), and opportunistic infection symptoms such as fever, coughing(4). 2) Mean CD4 cell counts(/mm3) were 53 +/- 72 totally, 22 +/- 27 for 8 dead patients at mean 2 month before, 91 +/- 87 for 7 living patients. There were not significant difference(p>0.05). 3) Serum beta2-microglobulin(MG;ug/ml) was measured at 12 patients, mean serum beta2-MG level was4.8 +/- 7.3 totally, 7.1 +/- 10.3 for 6 dead patients at mean 1.3 month before, 2.5 +/- 0.4 for 6 living patients. There were not significant(p>0.05). 4) At CBC examination, WBC(/mm3) was 5,932 +/- 2,899 totally, 5,452 +/- 3,436 for 10 dead patients, 6,500 +/- 2,221 for 9 living patients(p>0.05). Hb(g/dl) was 11,4 +/- 2.8 totally, 9.4 +/- 1.8 for dead patients, 13.6 +/- 1.8 for living patients(p<0.05). Lymphocyte count(/mm) was 1,255 +/- 800 totally, 731 +/- 424 for dead patients, 1,838716 for living patients(p<0.05). ESR(mm/h) was 72 +/- 47 totally, 97 +/- 33 for dead patients, 47 +/- 47 for living patients(p<0.05). 5) Opportunistic infections had developed at 14 patients, candidiasis 7, pneumocystis carinii pneumonia 5, tuberculosis 3, cytomegalovirus infection 2, herpes zoster 3, toxoplasmosis 1, cryptococcal infection 2, bacterial pneumonia 5, and herpes simplex l. Malignant lymphoma had developed in 1 patient. 6) Mean survival interval from diagnosis of HIV infection to death was 32.8 +/- 19.1 months, and the most common cause of death was pneumocystis carinii pneumonia, and other causes of death were meningitis, bacterial pneumonia and AIDS-wasting syndrome. Based on these results, We concluded that CD4 counts, serum beta2-microglobulin level, Hb, total lymphocyte count and ESR in AIDS patients are specific laboratory markers of progression and prognosis of AIDS, the most common opportunistic infection was candidiasis, and the most common cause of death in AIDS patients was pneumocystis carinii pneumonia.
