A 9 month-old male infant was admitted with the chief complaints of acute urinary retention and fever for 7 days. IVP showed the dilated upper urinary tracts. An expression cystogram demonstrated a bladder diverticulum without ureteral reflux. On cystoscopy, the left ureteral orifice was thought to be engulfed by the diverticulum and could not be seen The right ureteral orifice was normal findings. Diverticulectomy and left ureteroneocystostomy were performed. Postoperative course was uneventful and postoperative voiding cystography and IVP one month later showed an improvement of the upper urinary tracts. Diverticulum of the bladder it an infant was discussed.

Inflammatory polyposis of the colon is rare portion of the colon polyp entity. We experienced three patieats who suffered from colitis of unknown'etiology and discovered membranous retkular with/ without filiform polyp in the distal sigmoid colon of the them. Case 1, 56-year-old female, combined with basaloid cercinoma of the rectal canal that confirmed by pathology after abdominoperineal resection. So we obtained specimen of inflammtory polyp end tried to evaluate the mechanism of it. We found healed ulcer under the mucosal bridge. Case 2. 55-year-old male, had been suffered from irritable bowel syndrome. Prior to visit outpatient clinic, he complained tenesmus with diarrhea for a week. Inflammatory polyp was discovered by colonoacopy but his symptoms relieved by tranqulizers only. Case 3. 57-year-old male, has been a good health. He undertook colonoscopy for routine check thst revealed membranous reticular with filiform inflammatory polyp from distal sigmoid colon to hepatic flexure. Such shape of inflammatory polyp was not documented in Korea, so we reported three cases of it with review of the literature.

Intraocular lens power was calculated from data of axial length, corneal curvature, and anterior chamber depth in 112 eyes which underwent IOL implant surgery. Postoperative refractions of 112 eyes were analyzed into three groups such as the group of which constant A is 116.2, the group of which constant A is 116.8, and TI-59 system group. The results were as follows; 1. The A constant derived from retrograde analysis in our 112 cases was 116.2. In the cases of the constant A 116.2, error of predicted required spectacle lens power was -0.16D +/- 0.89 in relative average, 0.67D +/- 0.57 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculation by the constant 116.2 was 76.1% +/- 1.0D / 97.4% +/- 2.0D / +2.42 to -2.11D. 2. The specific constant A of intraocular lenses inserted in our hospital was 116.8. In the cases of the constant A 116.8, error of predicted required spectacle lens power was -0.39D +/- 0.88 in relative average, 0.75D +/- 0.60 in absolute average. Using the standard formula described by Hoffer, the accuracy of IOL power calculated by the constant A 116.8 was 72% +/- 1.0D / 96% +/- 2.0D / +2.34 to -2,50D. 3. In TI-59 system of IOL power calculation, error of predicted required spectacle lens power was -0.12D +/- 1.0D in relative average and 0.75D +/- 0.66 in absolute average. Using the staudard formula described by Hoffer, the accuracy of IOL power calculation in this method was 73% +/- 1.0D / 91.5% +/- 2.0D / +2.77 to -2.31D. 4. There was a significant difference between the error of the A constant 116.2 and that of 116.8(P. 0.05), but wasn't between the error of the A constant 116.2 and that of TI-59 system. 5. In the case of axial length 21mm +/- 0.5, the IOL power calculation by the A constant 116.2 was the most accurate among three groups.

Most of pneumoconiosis found in Korea can be categorized in coal worker's pneumoconiosis. However, in recent years, pneumoconiosis has been frequently found in the workers of manufacturing factories. Accordingly, this study was carried out to investigate relationship of dust exposure history and development and progress of pneumoconiosis. Chest radiographs, history of dust exposure, and other data of 144 workers, who were diagnosed as suspecter pneumoconiosis (0/l) or pneumoconiosis in special health examination center in Incheon from 1986 to 1996, were reviewed. The results were as follows ; 1. According to the type of main exposure, most common type of exposure was foundry dust(93workers, 64.6%), followed by welding fume(16workers, 11.1%), talc dust, lime dust and etc. 2. Among 144 workers, the history of dust exposure was investigated in 86 workers. Mean ages of 86 workers at the present study, initial exposure to the dusts, and at the time of initial diagnosis as having pneumoconiosis were 52.1, 29.1 and 46.5 years, respectively. The mean duration of exposure was 17.3 years. 3. Comparing the type of main exposure with dust exposure history, initially exposed age of welders, foundry workers, workers exposed to coal dust and other dusts were 24.6, 30.7, 28.0 and 28.5 years, respectively. Ages at the time of diagnosis as having pneumoconiosis of welders, foundry workers, coal dust and other dusts were 41.3, 49.3, 46.4 and 44.1 years, respectively. The duration of exposure to main dust of welders, foundry workers, workers exposed to coal dust and other dusts were 16.8, 18.2, 13.3 and 11.6 years, respectively. Therefore initially exposed age was significant difference between the welders and the foundry workers (p<.05). Age which was diagnosed pneumoconiosis was significant difference between the welders, workers exposed to other dusts and the foundry workers (p<.01). And exposure duration of main dust was significant difference between the workers exposed to other dusts and foundry workers (p<.01) 4. Initially diagnosed X-ray category of the workers were category 0/l (76workers, 52.8%), 1/0 (35workers, 24.3%) Therefore, workers' pneumoconiosis of manufacturing factories was mild, relatively. And there was no significant difference between initially diagnosed X-ray category of the workers and dust exposure history. 5. Among 97 workers, who could follow up more than 1 year, 60 workers(61.9%) were not changed, 24 workers (24.7%) were progressed, 13 workers (13.4%) were improved in their initially diagnosed X-ray category. Among 11 welders, initially diagnosed X-ray category of 5 welders(45.5%) were improved and of only 1 welder was progressed. But, among 19 workers exposed to other dusts, 10 (52.6%) workers were progressed and none of them were improved. 6. Among 53 workers, who were Initially diagnosed X-ray category was 0/l, 12 workers (22.6%) were progressed and 5 workers (9.4%) were improved in their initially diagnosed X-ray category. And among 40 workers, who were initially diagnosed X-ray category was 1, 12 workers(30.0%) were progressed and 7 workers(17.5%) were improved. Above results suggest that not a few workers of manufacturing factories have pneumoconiosis and their pneumoconiosis is progressed. Therefore, we have to prepare management plan and to study epidemiologic findings of pneumoconiosis with workers of manufacturing factories.

STUDY DESIGN: This study analyzes the results of selective thoracic fusion by segmental pedicle screw fixation in King type II adolescent idiopathic scoliosis(AIS). OBJECTIVES: To verify the efficacy of selective thoracic fusion by segmental pedicle screw fixation in King type II adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Decompensations following selective thoracic fusion in King type II adolescent idipathic scoliosis have been attributed to relative inability of the lumbar curves to accommodate correction of the thoracic curves. However, with segmental pedicle screw fixation, selective thoracic fusions yielded satisfactory results in most of the patients regardless of the lumbar curve characteristics. MATERIALS AND METHODS: Eighty patients subjected to selective thoracic fusion by segmental pedicle screw fixation were analyzed after a minimum follow-up of 2 years for deformity correction and spinal balance. Deformity correction was performed by derotation of rod contoured to the normal sagittal curve without additional compression or distraction. RESULTS: Mean preoperative thoracic curve of 53.3 was corrected to 20.3 showing a correction of 63.2%. The mean preoperative lumbar curve was 34.4 with a flexibility of 97.2% and mean lumboapical distance(LAD)of 18.0mm, L4 tilt of 8.0, and lumbar apical rotation (LAR) of 10.9. It was corrected to 16.5 showing a correction of 55.5%. All the patients were balanced clinically and radiologically. CONCLUSIONS: Selective thoracic fusion with segmental pedicle screw fixation and rod rotation offers a satisfactory correction of the deformity and maintenance of spinal balance in King type g AIS regardless of lumbar curve magnitude, LAD, L4 tilt or LAR.

The employment of segmental pedicle screw instrumentation has greatly enhanced the correction of scoliotic deformity. However there is still much controversy on the ability of the system to correct the rotational deformity. This prospective study with 12 idiopathic throacic scoliosis patients subjected to segmental pedicle screw instrumentation was performed to determine the effect of the system on the rotational deformity of idiopathic throacic scoliosis. In addition to the standing films to measure the magnitude of scoliotic curvatures, preand postoperative CT were utilized for the measurement and comparison of angle of rotation relative to the sagittal plane(RAsag.), relative rotation with reference to the upper and lower end vertebrae(RAend), relative rotation with reference to the sacrum(RAsac.), frontal translation(TF) and sagittal translation(TS) for the apical vertebrae. Despite the high correction rate obtained in the frontal plane(average 71.1%) and normalization of sagittal contour, the rotational corrections were statistically insignificant in all parameters and showed no significant correlation to the correction of the curvatures nor horizontal plane displacement as represented by the frontal and sagittal displacement. In conclusions, the segmental pedicle screw instrumentation with rod derotation does not produce significant derotation by itself.
