Lichen aureus is a rare disorder classified as a pigmented purpuric dermatosis. This case report is of a 46-year-old female in whom a coin sized, gold tinted, erythematous maculopapule developed on the right lower quadrant of the abdomen l0 years ago which showed characteristic histological findings of lichen aureus consisting of lymphohistiocytic infiltration in the upper dermis and extravasation of red blood cells.

PURPOSE: The purpose of the study is to investigate the correlation between the symptoms and the incidence of anatomical variant without mucosal abnormality. MATERIALS AND METHODS: Out of 892 patients with CT performed for the evaluation of sinus disease symptoms between March 1991 and March 1993, we observed the anatomic variations in 82 symptomatic patients without mucosal abnormality(male:female=43:39, mean age 36. 4 years). The control group included 88 patients with facial bone CT performed for the evaluation of trauma during the same period while patients with recent paranasal sinusitis were excluded. (male:female=76:12, mean age 22. 4 years). The scouis were performed with 5-ram section thickness from posterior margin of sphenoid sinus to anterior margin of posterior ethmoid and then with 3 mm thickness from anterior margin of posterior ethmoid to anterior margin of frontal sinus. The artatomic variations included nasoseptal deviation, concha bullosa, Hailer cells, Agger nasi cells, etc. RESULTS: The anatomic variations were demonstrated in 71 our of 82 symptomatic patients(86. 5%), whereas they were seen 26 of 88 patients(29. 5%) in control group. CONCLUSION: Our data suggest that there is a possible causal relationship between anatomic variations and symptomas. Even though without accompaning mucosal abnormalities, anatomic variations could contribute simply to its symptomas. ^natomic variants may obstruct or narrow the airway, leading to turbulating air flow or interrupting ucociliary movement, and finally may produce a series os symptoms.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

Bladder neck suspension to replace the bladder neck and proximal urethra into a high fixed retropubic position is paramount in the surgical treatment of genuine stress incontinence. Thirteen patients with grade II stress incontinence and one patient with grade III one underwent the Raz bladder neck suspension. All patients had no previous anti-incontinence operation. radiation therapy and pelvic trauma. Thirteen patients(93%) were cured and one patient(7%) improved with mean Follow-up period of 26 months. One failure case was due to insufficient suspension toward high retropubic position. The complications were not significant except temporary urinary retention of 2 to 9 days. The Raz bladder neck suspension providing good mobilization of paraurethral tissues is considerable way to the treatment of all types of genuine stress incontinence except those secondary to urethral intrinsic damage.

This study was undertaken to analyze the growth of mandible in surgically repaired unilateral cleft lip and palate. The subjects consisted of 63 unilateral cleft lip and palate individuals, 60 class III malocclusion and 60 normal occlusions ranging from 6 to 15 years old. Each group was divided into two age groups. (6-10 Y and 11-15 Y) The results obtained from UCLP compared with other groups were as follows: 1. The anteroposterior position of the chin was similar to that of the normal occlusions. 2. The shape of the mandible was similar to that of the class III malocclusions. 3. In mandibular size, ramus height was the smallest among three groups, but body length and overall mandibular length were similar to those of the normal occlusions. 4. The lower border of the mandible was the steepest among three groups and strong vertical or clockwise growth tendency was indicated. 5. The position of condyle in relation to the cranial base showed little difference in three groups. 6. In older age group, vertical growth tendency of the mandible decreased more or less.

This study was performed to locate the anteroposterior position of the center of resistance of upper anterior teeth when intrusive forces are acted on them by applying segmented arch mechanics. Three-dimensional finite elernent model of upper six anterior teeth, periodontal ligament and alveolar bone was constructed The locations of the center of resistance were compared according to the three variables, which are number of teeth contained in anterior segment, axial inclination of anterior teeth, and degree of alveolar bone loss. The following conclusions were drawn from this study; 1. When the axial inclination and alveolar bone height were normal, the locations of center of resistance of anterior segment according to the number of teeth contained were as follows; 1). In 2 teeth segment, the center of resistance was located in the distal area of lateral incisor bracket 2) In 4 teeth segment, the center of resistance was located in the distal 2/3 of the distance between the brackets of lateral incisor and canine. 3) In 6 teeth segment, the center of resistance was located in 3mm distal of canine bracket, which is interproxirnal area. between canine and 1st premolar. 4) As the number of teeth contained in anterior segment increased, the center of resistance shifted to the distal side. 2. As the labial inclination of incisors increased, the center of resistance shifted to the distal side. 3. As the alveolar bone loss increased, the center of resistance shifted to the distal side.

OBJECTIVES: To confirm the HAVS in workers exposed to hand-arm vibration with using the objective diagnostic methods METHODS: Several tests were used to help substantiate a clinical diagnosis of HAVS. Some other diseases were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was evaluated for considering HAVS. Peripheral vascular changes were examined by a cold provocation test. An electromyography was implemented to ascertain the peripheral neural changes. RESULTS: 8 workers with symptoms in hands & fingers, exposed to hand-arm vibration were examined. Some other diseases(primary Raynauds disease, secondary Raynauds disease in not occupational origin) were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was 7. 9 m/sec2. The recovery time of a skin temperature followed finger cooling was significantly prolonged in 6 workers with HAVS. The nerve conduction velocity was reduced in 6 workers with HAVS. CONCLUSIONS: So we report 6 cases of HAVS in grinding workers exposed to hand-arm vibration diagnosed objectively by an exclusion of some other disease, handarm vibration acceleration level, cold provocation test, electromyography.

It is a rare occurrence that cervical cancer and aplastic anemia are combined, but eight cases were reported since Fujiu's report in 1968. There has been no one who have reported the case of like this in Korea. And so, we report this case for the support of idea of treatment in aplastic anemia patient combined with cervical cancer. The knowledges required are early detection of malignancy and the individualization of the treatment according to the status of the patient, the bone marrow function saving procedure and the prevention of the patient from death involved with bleeding and sepsis induced by infection.
