OBJECTIVE: Ventriculoperitoneal (VP) shunt complication is a major obstacle in the management of hydrocephalus. To study the differences of VP shunt complications between children and adults, we analyzed shunt revision surgery performed at our hospital during the past 10 years. METHODS: Patients who had undergone shunt revision surgery from January 2001 to December 2010 were evaluated retrospectively by chart review about age distribution, etiology of hydrocephalus, and causes of revision. Patients were grouped into below and above 20 years old. RESULTS: Among 528 cases of VP shunt surgery performed in our hospital over 10 years, 146 (27.7%) were revision surgery. Infection and obstruction were the most common causes of revision. Fifty-one patients were operated on within 1 month after original VP shunt surgery. Thirty-six of 46 infection cases were operated before 6 months after the initial VP shunt. Incidence of shunt catheter fracture was higher in younger patients compared to older. Two of 8 fractured catheters in the younger group were due to calcification and degradation of shunt catheters with fibrous adhesion to surrounding tissue. CONCLUSION: The complications of VP shunts were different between children and adults. The incidence of shunt catheter fracture was higher in younger patients. Degradation of shunt catheter associated with surrounding tissue calcification could be one of the reasons of the difference in facture rates.

PURPOSE: To investigate the error tendency between preoperative target diopter and postoperative manifest refraction in cataract surgery cases and the effect of axial length and vitrectomy on refractive error (RE). METHODS: We retrospectively studied 90 eyes of 90 patients who underwent cataract surgery. The power of intraocular lens (IOL) was calculated by SRK/T formula. Patients were devided into four groups based on axial length (AXL) and the past history of vitrectomy. RESULTS: The mean of RE showed no significant difference between groups. But an increasing AXL was associated with increased myopic shift with normal range AXL (< or =24.4 mm) (r = -0.502, p = 0.005) and increased hyperopic shift with long AXL (>24.4 mm) (r = 0.718, p < 0.001). In vitrectomized eyes, it showed no significant refractive shift with both normal range and long AXL. CONCLUSIONS: When determining IOL power using SRK/T formula in nonvitrectomized eyes, postoperative refractive shift based on axial length should be considered.

PURPOSE: There is yet no ideal single staging system for hepatocellular carcinoma (HCC). The aim of this study was to analyze HCC survival times according to the TNM, Okuda, CLIP, JIS, and BCLC staging systems and their prognostic discrimination ability. METHODS: A retrospective analysis of medical records and statistical data from the Korean statistical information service was done for HCC patients diagnosed at Bundang CHA hospital between June, 1992 and February, 2009. RESULTS: During follow-up, 121 (72%) of 168 people died and 1, 3 and 5 year overall survival rates were, respectively, 58%, 35% and 25%. In the analysis of discriminative ability of each staging system, the CLIP staging system showed the highest LR chi-square value, and the lowest AIC value (p<0.05). Therefore, the CLIP staging system appears to be superior to the other systems. CONCLUSION: Of the 5 staging systems in this study, the CLIP staging system was superior to the other systems, but the results of many other studies from different countries have varied. It is necessary to establish the staging system suitable for each country's actual circumstances.

Churg-Strauss syndrome is a clinicopathologic disorder of severe asthma, fever , and eosinophilia together with systemic vasculitis involving various organ systems. Characteristic cutaneous lesions include erythematous maculopapules resembling erythema multiforme, hemorrhagic lesions, and cutaneous and subcutaneous nodules. Histologically, extravascular granuloma and leukocytoclastic vasculitis are the most common findings. We report a case of 40-year-old woman who presented with generalized multiple hemorrhagic bullae that had developed 1 month ago. Previously, She had allergic rhinitis and asthma. Laboratory studies revealed peripheral blood eosinophilia, and positive p-ANCA. Skin biopsy revealed eosinophilic infiltrates and leukocytoclastic vasculitis.

BACKGROUND: Korean versions of Fat Phobia Scale (short form) (F-scale), Beliefs About Obese Persons Scale (BAOP), and Attitudes Toward Obese Persons Scale (ATOP) which are scales of rating weight bias were assessed to find out the reliability and validity. METHODS: Korean versions of F-scale, BAOP, and ATOP were completed twice by 165 adults (85 males, 80 females; 73 hospital staffs, and 92 teachers). Validity was tested using Spearman correlation and factor analysis. Reliability was analyzed using test-retest analyses (Spearman Rho value). RESULTS: Using factor analyses, F-scale comprised of three factors explaining 55.20% of the total variance, BAOP two factors explaining 53.3% of the total variance, and ATOP six factors explaining 61.61% of the total variance. Spearman correlation between F-scale and ATOP was -0.28 to -0.36 (P < 0.05), suggesting that people who worried about being obese tended to have negative attitudes against obesity. The correlation between F-scale and BAOP was -0.25 to -0.27 (P < 0.05), meaning that people who worried about being obese had a tendency to blame obesity on environmental factors. Cronbach's alpha coefficients were 0.79 to 0.90 for F-scale, 0.34 to 0.38 for BAOP and 0.82 to 0.87 for ATOP. Spearman Rho values were 0.47 for F-scale, 0.50 for BAOP, and 0.47 for ATOP (P < 0.05). The scores of each scale were not related to subjects' sex, BMI, body perception, and weight control efforts, while for ATOP scores older subjects were more likely to have a negative view for obesity (P < 0.05). CONCLUSION: The Korean version of F-scale, ATOP and BAOP could be considered as a tool to evaluate weight-bias however, further study is needed for appropriate application.

Tufted angioma is a rare, acquired vascular tumor, most commonly presenting in the first year of life, which was first described by Wilson Jones in 1979. Spontaneous resolution of this tumor are known to be very rare and local recurrence often occurs unless the tumor is excised completely. We present two cases of tufted angioma developed in two 1-year-old girls. Skin biopsy in a case showed compatible findings with tufted angioma and the other was diagnosed at an other hospital. The lesions were treated with intralesional injections of triamcinolone acetonide and showed marked improvement. During follow up period, the lesions kept improving.

PURPOSE: To investigate the influence of preoperative endothelial cell loss on the outcome of keratoplasty for keratoconus in imported donor corneas. METHODS: Eighteen imported corneas used in keratoplasty for keratoconus patients were evaluated. Corneal endothelial cell density at the moment of preservation was obtained from the medical records and was measured immediately before the keratoplasty. Correlation of the endothelial cell loss count before and after keratoplasty was analyzed and postoperative endothelial cell loss count according to the range of preoperative endothelial cell loss was evaluated. RESULTS: Mean endothelial cell loss before and after keratoplasty was 258.94 +/- 128.58 cells/mm2 and 355.44 +/- 371.83 cells/mm2, respectively. There was a positive correlation between preoperative and postoperative endothelial cell loss count (r = 0.431, p = 0.074). The results showed statistically significant higher endothelial cell loss count after keratoplasty in the range above 250 cells/mm2 rather than below 250 cells/mm2 of preoperative endothelial cell loss count (p = 0.033). CONCLUSIONS: The preoperative decrease in endothelial cell density affected the endothelial cell loss after keratoplasty for keratoconus in imported donor corneas.

PURPOSE: To evaluate the accuracy of the chosen formula in short eyes and the effect of the anterior chamber depth (ACD) and corneal refractive power on the accuracy. METHODS: A total of 251 eyes out of 185 patients (axial length below 22.0 mm) who underwent cataract surgery in our hospital were retrospectively studied. Introcular lens (IOL) power was calculated with the Hoffer Q, SRK II, SRK-T and Holladay 1 formulas and refractive outcome was measured. Patients were divided into 2 groups based on ACD. The accuracy of the 4 formulas was compared and the errors according to the ACD were also evaluated. RESULTS: In eyes with short axial lengths, all formulas showed a tendency for hyperopic shifts. The Hoffer Q formula showed significantly high predictive accuracy. This tendency for hyperopic shifts was similar in the eyes with extremely short axial length, but a large refractive error deviation was observed. The 2 groups based on ACD showed no significant difference in the refractive error, but the group with deep ACD had a tendency for hyperopic shifts. The difference of the calculated IOL power between the 4 formulas was more pronounced in eyes with lower corneal refractive power. CONCLUSIONS: In eyes with short axial lengths, preoperative ACD and corneal refractive power had an influence on the accuracies of predicted IOL power. Therefore, these factors should be considered in IOL power determination.

BACKGROUND: Airway hyperresponsiveness has been estimated by means of forced expiratory volume in 1 second(FEV1) through the methacholine inhalation challenge test(MIC). But it is difficult to do the forced expiratory maneuver for measuring FEV1 in children. It is relatively easy to measure peak expiratory flow rate(PEFR) by portable peak expiratory flow meter(PEFM). OBJECTIVE: The purpose of this study is to evaluate whether FEV1 by means of MIC could be appropriately replaced by the measurement of PEFR. METHOD: A total of 30 subjects aged from 7 to 15 years with recurrent cough were enrolled in this study. MIC was performed with stepwise cumulative dose and both FEV1 and PEFR were measured at each step. The study was discontiued at the point of 20% reduction of FEV1 from the baseline value. FEV1 and PEFR were measured after salbutamol was inhaled by nebulizer. RESULT: There were significant correlations with reduction rates(r1=0.59, P<0.05) and recovery rates(r2=0.60, P<0.05) between FEV1 and PEFR, respectively. The sensitivity, specificity, positive predictive and negative predictive value of PEFR(PC20-FEV1 and PC20-PEFR<8 mg/ml) were 63.6, 94.7, 87.8 and 81.8%, respectively(P<0.05). CONCLUSION: Although PEFR measurement by means of MIC revealed low sensitivity, high specificity and positive predictive value could be obtained. These results indicate that PEFR measurement by means of MIC may be useful for diagnosing the airway hyperresponsiveness in children, although it cannot be replaced completely.
