Soft tissue perineurioma is a very rare tumor composed of entirely of neoplastic perineurial cells. A 54-year-old woman presented with a palpable mass in the right lower leg. The mass was excised. Grossly, the tumor measured 2.0x2.0x1.5 cm. The cut surface was well circumscribed, pale pinkish gray, and rubbery soft. Histological examination showed that the tumor was composed of spindle cells within collagenous and myxoid stroma. The tumor cells had elongated, tapering nuclei with long and thin cytoplasmic processes, and were arranged in fascicular, whorled, and storiform pattern. The tumor cells were positive for epithelial membrane antigen and collagen type IV and negative for S-100 protein. Ultrastructurally, tumor cells showed long and thin cytoplasmic processes, pinocytic vesicles, and incomplete external lamina. The diagnosis of soft tissue perineurioma was confirmed by immunohistochemical stain and ultrastructural study.

We present a case which seems identical to REM(Reticular Erythematous Mucinosis) syndrome in 26 year-old male. The lesion was initiated about 2 years ago and waxed and waned. The clinical findings were localized, grouped, erythematous papules and vesicles on the anterior middle chest with intermittent mild itching. Histopathology showed normal epidermis, extensive mucin deposition, telangiectasia and mild perivascular round cell infiltrations on the upper dermis. The mucin was stainable with alcian blue at pH 2. 5, but was not stained by either PAS or mucicarmine. Skin lesions were not responded to the oral steroid, but improved slowly after topical application of 5% para-aminobenzoic acid in ethanol for 9 months. The lesion does not recur until present time.

Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.

PURPOSE: We report two cases of tube erosion after Ahmed valve implantation, treated with Amniotic Membrane Transplantation. METHODS: Erosion of conjunctiva over tube occured in 2 female patients with Ahmed valve implantation. They were treated with pericardial patch grafts and conjunctival free graft with amniotic membrane epithelial side up transplantation. RESULTS: No recurrent tube erosion has been found since then. Intraocular pressure has been maintained well for 12-14 months of follow-up. CONCLUSIONS: In cases of tube erosion, additional amniotic membrane transplantation can improve surgical success.

We reviewed 20 cases for the surgical effect of the vertical transposition of the horizontal rectus muscle for AV syndrome without significant oblique dysfuction. We performed vertical tranposition of the horizontal rectus muscle with standard recession and resection procedure and followed up at least six months. Sixteen cases were V syndrome and four cases were A syndrome. Medial rectus was moved toward the apex of the A or V, and the lateral rectus was moved to the opposite side of the apex of the A or V. The amount of transposition was adjusted according to the amount of vertical incomitance. If the vertical incomitance was 10delta, 15delta, 20deltaand 25delta, vertical transposition of rectus muscle was 1/4 TW[tendon width], 1/2 TW, 3/4 TW amd 1 TW, respectively. We achieved an average of 12.9deltareduction by 1/4 TW transposition, 14.4deltareduction by 1/2 TW transposition, 13.3delta reduction by 3/4 TW transposition, 19.0deltareduction by 1 TW transposition. We also achieved an average of 5.2delta/mm effect by 1/4 TW transposition, 2.9delta/mm effect by 1/2 TW transposition, 2.4 delta/mm effect by 3/4 TW transposition, 1.9delta/mm effect by 1 TW transposition. The vertical transposition of the horizontal rectus muscle for AV syndrome without significant oblique dysfuction showed good result and the amount of correction per mm of vertical transposition seemed to decrease as the amount of transposition increased, even though the total amount of correction showed a trend toward increasing [Fig.1, 2].

Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

PURPOSE: The expected corneal ablation amount was compared to the achieved corneal ablation amount in two different excimer laser systems. METHODS: One hundred twenty eyes were recieved Laser In Situ Keratomileusis (LASIK) for the correction of myopia. LASIK was performed with MEL-60 excimer laser and Schwind Multiscan excimer laser system. The central corneal thickness was measured preoperatively, 1 week and 1 month postoperatively by using ultrasonic pachymetry. RESULTS: In eyes with MEL-60 excimer laser, the average expected corneal ablation amount was 81+/-26micro meter and average achieved corneal ablation amount at postoperative one week was 65+/-26 micro meter. There was statistical difference between expected and achieved ablation amount. (p<0.001, paired samples test) In eyes with Schwind Multiscan excimer laser, the average expected corneal ablation amount was 69+/-25 micro meter and average achieved corneal ablation amount at postoperative one week was 69+/-25 micro meter. There was no statistical difference between expected and achieved ablation amount (p=0.761, paired samples test). CONCLUSIONS: The pachymetry at postoperative one week appears to be an useful method to measure the real corneal ablation amount by LASIK with various excimer lasers. Residual stromal bed thickness after LASIK can be presumed, and it helps to decide modality of retreatment.

PURPOSE: This project was designed to study the effectiveness and safety of Dream lens(TM) (OK B+ series lenses, Contex, USA) in correcting myopia in a population of school children, under 13 years old. METHODS: Twenty-three school children aged 7 to 13 years followed over a 3-month period were fitted with lenses in the Vision Eye Center from September 2002 to March 2003. Slit lamp examination, uncorrected visual acuity, autorefraction and autokeratometry by Canon RK-5 and topography were measured at baseline and at 1week, 1 month, and 3 months after the lenses were worn. RESULTS: The mean baseline autorefraction was -2.54 +/- 1.00 diopters (range: -0.63~-4.00) and baseline uncorrected visual acuity over 0.5 was 11.1% and over 0.8 was 0%. Vision correction of over 0.8 was found in 80% of the cases in the first 1 week, 78% at 1 month, 91% at 3 months with the most rapid improvement occurring during the first 1 week. Superficial punctate keratitis occurred in 4 of 45 eyes, but there was no other pathologic problem. CONCLUSIONS: Dream lens is an effective and safe means of temporarily reducing myopia in a certain range of myopic patients; however, further studies are needed to determine the long-term effects on the eye health.

PURPOSE: To verify the usefulness of left portal vein angle (LPVA) on CT scan in the diagnosis of liver cirrhosis and to compare its diagnostic value with that of caudate to right lobe ratio (C/RL ratio). MATERIALS AND METHODS: LPVA, an angle formed by a vertical line and a line connecting the center of the vertebral body to the umbilical point of the left portal vein, and C/RL ratio were measured on CT scans of 100 cirrhotic and 100 normal livers. Diagnostic values of LPVA and C/RL ratio were compared statistically. RESULTS: The mean of LPVA was 18.9 degrees(SD; 7.6) for normal livers and 25.8 degreesSD; 8.4) for cirrhotic livers (P<0.001). The mean of C/RL ratio was 0.47(SD; 1.10) for normal livers and 0.58(SD;0.14) for cirrhotic livers (P<0.001). When LPVA was greater than 30 degreesliver cirrhosis was diagnosed with 36% sensitivity and 92% specificity. When C/RL ratio was greater than 0.60, the diagnose of liver cirrhosis was with 41% sensitivity and 90% specificity. There was no significant difference of the diagnostic accuracy between LPVA and C/R L ratio in ROC analysis. CONCLUSION: Both LPVA and C/RL ratio are useful diagnostic indices of liver cirrhosis on CTscan. LPVA is more convenient to measure than C/RL ratio.
