The clinicolaboratory findings, cardiac catheterization, and outcome of operation were analyzed in 78 patients with tetralogy of Fallot, which were diagnosed by echocardiography, cardiac catheterization, and a cardiac angiography and confirmed by operation at Dong San Hospital, Keimyung University, during a 4(1/2)-year period from January 1984 to June 1988. The following results were obtained : 1) Out of the 78 cases, 45 were male and 64 were female. 2) The electrocardiogram showed right axis deviation in 71 cases(91%) and right ventricular hypertrophy in 66 cases(84.6%). 3) Chest X-ray revealed that, the cardiothoracic ratio was normal or decreased in 68 cases(87.3%), and cardiac apex elevation was noticed in 57 cases(73%). 4) Pulmonary stenosis were chiefly valvular and infundibular type(53.8%). 5) The associated heart diseases with TOF were patent foramen ovale(64.1%), right sided aortic arch(19.2%), and secundum ASD(10.3%), in that order. 6) There was an intimate correlation between secondary polycythemia and thrombocytopenia. 7) Among the 78 Cases, 73 cases had total correction, 1 case had shunt operation, and 4cases had total correction after shunt operation. The highest mortality rate occurred in the cases of total correction after shunt operation(25%). The cases with a main pulmonary artery size of 1/3 to 2/3 against, the aorta had a higher mortality than the other group, and no cases expired in the group with a ratio of more than 2/3. The overall surgical mortality was 8.9%.

PURPOSE: To reduce complications and provide proper management for better clinical outcomes in the treatment of macular edema through a large-scale analysis of the incidence and risk factors for complications of intravitreal triamcinolone injection. METHODS: The medical records of 490 eyes that received intravitreal triamcinolone (4.0 mg) injection for treatment of macular edema caused by various diseases were retrospectively reviewed, and relevant parameters were included in a multivariate regression model. RESULTS: Vitrectomized (p < 0.001) and pseudophakic (p = 0.054) eyes were less likely to exhibit an intraocular pressure increase, but glaucoma (p < 0.001) and young age (p = 0.073) were found to be significant risk factors for this complication. Vitrectomized eyes (p = 0.011), diabetic macular edema (p < 0.001), secondary ocular hypertension (p = 0.029) and old age (p = 0.059) were associated with cataract progression. Three consecutive case of sterile endophthalmitis, which differs from bacterial endophthalmitis in clinical course and prognosis, occurred during the same period. CONCLUSIONS: Risk factors and the incidence of complications after intravitreal triamcinolone injection should be evaluated through regular follow-up evaluation to ensure proper management and a better prognosis.

PURPOSE: Bone involvement is known to develop in 40-70Yo of pediatric acute leukemia. We aimed to analyze the clinical course and result of therapy in pediatric acute leukemia with bone involvement. METHODS: Twenty-seven patients diagnosed as pediatric acute leukemia at Dong San Medical Center from Jan. 1996 to Aug. 1998 were evaluated. According to bone X-ray and whole body bone scan, the patients were divided into two groups. RESULTS: Twenty-seven patients were enrolled in this study with 14 patients(52Yo) showing definite bone involvement on simple X-ray or bone scan. Mean age of patients with bone involvement was 5.5 years. Regarding the type of leukemia, 9 patients(64%) were acute lymphocytic leukemia. Ten patients(71%) out of 14 with bone involvement complained of bone pain at the involved bony site. Site of involvement was most frequent in the lower extremity. On simple X-ray, osteolytic lesion was found in 7 patients(50%), diffuse osteopenia in 2 patients(14%) and pathologic fracture in 2 patients(14%). In bone scan, radioactivity was increased in whole cases of patients with bone involvement. Thirteen patients(93%) were completely remitted by chemo-therapy, but, one AML patient died due to induction failure. CONCLUSION: Bone involvement occured in 52% of pediatric acute leukemia. Bone involvement was more frequent in male patients in the lower extremity, and osteolytic lesion was the most frequent finding on simple X-ray. There was no relevence between bone involvement and prognosis. Further study will be needed to evaluate long-term survival and prognosis. (J Korean Pediatr Soc 2000;43:806-813)

PURPOSE: To report 2 different cases of postoperative endophthalmitis caused by Stenotrophomonas maltophilia after cataract surgery. CASE SUMMARY: A 73-year-old male with diabetes mellitus developed severe pain in the right eye 2 weeks after cataract surgery. The patient was hospitalized with a diagnosis of infectious endophthalmitis, and vitrectomy was performed. Cultures of aqueous humor and vitreous aspirate revealed S. maltophilia. On day 30 after vitrectomy, his visual acuity had improved to 20/20 and there were no recurrences. A 61-year-old female with no significant past medical history was referred for uveitis or delayed onset endophthalmitis 30 days after cataract surgery. An anterior chamber tapping and cultures were performed. S. maltophilia and Aspergillus fumigatus were isolated. The patient received antibiotics and antifungal agents and her visual acuity improved to 20/25. CONCLUSIONS: S. maltophilia has been considered a life-threatening systemic opportunistic infection; however, the organism has recently been reported as an exogenous pathogen of endophthalmitis following cataract surgery. Herein, 2 different cases of S. maltophilia endophthalmitis after cataract surgery are presented and compared with previous case reports.

PURPOSE: To evaluate the effects of simvastatin on the catalase expression in human retinal pigment epithelium. METHODS: Retinal pigment epithelial (RPE) cells were incubated for 6 hours and 24 hours with various concentrations of simvastatin. In addition, RPE cells were incubated with 200 microM of H2O2 and various concentrations of simvastatin. After incubation, real-time polymerase chain reaction (PCR) was performed to examine the catalase messenger ribonucleic acid (mRNA) expression and a catalase assay was performed to examine the catalase activity in RPE. Intracellular reactive oxygen species (ROS) was measured using a fluorescence activated cell sorter (FACS). RESULTS: Simvastatin increased the amount of catalase mRNA and catalase activity at 10 microM in RPE cells. Under oxidative stress (200 microM of H2O2), 2.5 microM of simvastatin increased the catalase mRNA expression and 5 microM of simvastatin increased catalase activity in RPE cells. In addition, simvastatin reduced free radical formation but this effect was diminished in the presence of an irreversible catalase inhibitor, 3-amino-1,2,4-triazole (3-AT). CONCLUSIONS: Simvastatin exhibits anti-oxidative effects by inducing the catalase expression in human RPE cells. This anti-oxidative effect may be beneficial for preventing age-related macular degeneration induced by oxidative stress.

PURPOSE: To evaluate the effectiveness of a combined procedure of peeling the internal limiting membrane with vitrectomy in diabetic macular edema. METHODS: This study comprised 16 eyes of 16 patients hospitalized during a 1-year period. They were randomized to either a vitrectomy group (10 eyes in 10 patients) or to a combined procedure group (6 eyes in 6 patients). Preoperative and postoperative macular center thickness, best corrected visual acuity and postoperative complications 4 months postoperative were investigated. RESULTS: There were no statistically significant differences in the mean values of preoperative and postoperative best corrected visual acuity (logMAR) between the two groups. The mean values of preoperative and postoperative macular center thickness in the vitrectomy group were respectively 509.50+/-36.77 and 332.60+/-91.73; while in the combined procedure group, they were 516.17+/-55.43 and 333.83+/-51.64. Again, there were no statistically significant differences between the two groups. At the 4-month follow-up, decreased visual acuity was found in 3 eyes of the vitrectomy group and in 2 eyes of the combined procedure group. Vitreous hemorrhage (3 eyes) and tractional retinal detachment (1 eye) were found in the vitrectomy group and vitreous hemorrhage (2 eyes) was diagnosed in the combined group. CONCLUSIONS: In our study, vitrectomy with peeling of the internal limiting membrane was not more effective than vitrectomy alone in decreasing macular edema or in improving best corrected visual acuity. Additional studies of the combined procedure are needed to verify this result.
