1. Partial nephrectomy was done on 7 cases of various renal diseases including 5 cases of renal tuberculosis, 1 case of renal stone and l case of focal nephritis.Satisfactory results were noted in 5 cases of them. while in other 2 cases secondary nephrectomy was indicated because of severe postoperative shock and profuse hematuria. 2. Through the clinical experiences on the partial nephrectomy, it is believed that the method of choice in effective hemostasis during the operation should be included (a) the blunt division of renal parenchyma using scalpel han8e, (b) accurate ligation of the parenchymal vessels found during the division and (c) suture of the arcuate vessels at the corticomedullary junction under the aid of renal arterial clamping. On the other hand, tense and deep mattress suture to get indirect hemostasis is considered to be inadequate and unfavorable for the method having brought parenchymal necrosis and profuse delayed hemorrhage in a few instances. 3. Duration of renal arterial clamping using Bulldog clamp ranged about 30 minutes or so, and no definite renalinjury followed after the procedure.

BACKGROUND: Pityriasis versicolor(PV) is a superficial mycosis, theoretically unusual in children. Epidemiologic and clinical data for children with PV under 14 years were collected. OBJECTIVE: The purpose of this study was to evaluate the clinical features of PV in the young. METHOD: We included all cases of PV in patients under 14 years of age observed in our department from 1981 to 1995. All cases were diagnosed on the basis of clinical criteria and were confirmed by microscopic examination. RESULTS: From 1981 to 1995 we encountered 32 cases of PV in children, compared with 637 cases in adults; thus children represented 4.7% of all cases. The ratio of male to female was l. 7:1. Among the age groups, the incidence was the highest in the 10-14 years(43%). The monthly prevalence was the highest in August. Distribution of the lesions were the face(40.9%), neck (25%), chest(13.6%), back(11.3%), extremities(6.8%) and abdomen(2.2%). The incidence of hypopigmented lesions was 70.4% and that of hyperpigmented lesions was 29.6%. CONCLUSION: This study confirms that the face is a predilectionl site for PV in children and all facial lesions are hypopigmented. Other clinical features are variable and similar to those of adults.

Percutaneous transhepatic cholangiography(PTC) is of value in differential diagnosis of cholestatic diseases. Authors had performed PTC in 120 patients with flexible needle of 23 gauge at the Department of Radiology, KangNam St, Mary's Hospital and Myung Dong St. Mary's Hospital during the period from Jan. 1976 to April 1980. PTC was accomplished successfully in 112 of 120 patients. Diagnoses included cholangiocarcinomas (27 cases), arcinomas ofpancreas head (21 cases), ampullary carcinomas (4 cases), metastatic carcinomas(4 cases), metastatic carcinomas (5cases), bile duct stones(27 cases), sclerosing cholangitis(6 cases), hepatitis(6 cases), liver cirrhosis(6 cases), post operative adhesions(5 cases), chronic pancreatitis(3 cases), stomach carcinomas(3 cases), clonorchiasis(2cases), blood clot (1 case), and remaining normal 4 cases. Some characteristic PTC findings were (1) segmentalannular narrowing and abrupt complete obstruction and polypoid filling defects of the bile duct incholangiocarcinoma, (2) typical nipple or rat-tail appearance of the distal commmon bile duct in pancreatic headcarcinoma, (3) single or multiple sharply and smoothly outlined filling defects whthin bile duct in all cases ofstones, (4) complete obstruction with shallow concavity in ampullary carcinoma, (5) diffuse or segmental narrowingof the intrahepatic bile duct and common bile duct in sclerosing cholangitis, (6) multiple tiny polypoid fillingdefects of gallbladder, common hepatic duct, and common bile duct in clonorchiasis, (7) normal appearance inhepatitis. The overall diagnostic accuracy of PTC in 66 operated cases was 89.4%, and complications following the examination were signficantly reduced by using a fine flexible needle(23 gauge). From the present study it is concluded as follows; 1. To evaluate obstructed or stenosed site accurately, aspiration of bile juice must bepreceded by a 23 gauge needle connected to either 10mo or 5ml syringe. 2. To diagose carcinoma of hte ampullaryportion, serial spot filmings were indispensible ot demonstrated modified appearance of obstructive lesions due tocontraction of Oddi sphincter. 3. In contrast to other reports, the most common site of cholangiocarcinomas wasthe common hepatic duct (12 of 27 cases) in our series. Rat-tail appearance was seen in both pancreatic headcarcinoma and carcinoma involving the distal end of the common bile duct. 4. PTC was a more valuable method for diagnosis of clonorchiasis.

Two cases of traumatic bilateral anterior and posterior dislocation of hip are reported. Dislocations were developed by a traffic accident as a passenger injury in truck. In both cases, the fractued femoral heads appeared posteriorly dislocated on x-ray examination and one of them was removed through posterior approach. Primary arthroplasty for operated hip was not attempted because the patient was young and the defect seemed to be unrelated to weight bearing surface. Extreme rarity of its incidence and curious uncertain mechanism of injury urge to report these cases.

PURPOSE: This study was retrospectively conducted to evaluate the clinical results of consecutive 167 myopic eyes of 117 patients undergoing laser in situ keratomileusis(LASIK) for myopia with either of the two excimer lasers, which differ in the method of laser delivery: flying spot scanning versus broad beam. METHODS: According to the laser used, the treated eyes were divided into two groups: Group I, 84 eyes of 58 patients with LaserScan LSX(R)(Lasersight Inc., USA); Group II, 83 eyes of 59 patients with OmniMed II(R)(Summit, USA). Each patient had been followed up for more than 6 months after surgery. Only single procedure outcomes were included. Mean preoperative spherical equivalents(SE) were -5.67+/-1.79 D(range:-1.50~-9.75 D) in group I and -6.40+/-1.79 D(range:-3.50~-9.75 D) in group II. RESULTS: At postoperative 6 months, mean uncorrected visual acuity increased to 0.94 in group I and 0.88 in group II. Uncorrected visual acuity of 20/40 or better occurred in 100% of group I and 96.4% of group II, and of 20/20 or better, in 57.2% and 48.2%, respectively. No eye in either group lost more than 1 line of best-corrected visual acuity. Mean SEs at postoperative 6 months were -0.28+/-0.50 D in group I and -0.55+/-0.60 D in group II(P<0.05). Manifest SEs were within +/-1.00 D in 97.6% of group I and 84.3% of group II, and +/-0.50 D in 73.8% and 60.2%, respectively. Intra- or postoperative complications were subconjunctival hemorrhage(4 eyes, group I; 5 eyes, group II), Sands of Sahara syndrome(7 eyes, group I; 5 eyes, group II), epithelial ingrowth(1 eye, group II only) and infectious keratitis(1 eye, group II only). No case had a central island or irregular astigmatism postoperatively. CONCLUSIONS: Our study suggests that LASIK using the LaserScan LSX(R)excimer effectively reduces myopia compared with OmniMed II(R). However, its predictability decreased as the attempted correction increased. LASIK for myopia less than -10 D with the LaserScan LSX(R)provided satisfactory refractive results that compare well with other reports in the literature.
