PURPOSE: The aim of this study was to investigate the changes in and implications of preoperative and postoperative serum uric acid levels in patients with living donor nephrectomy. MATERIALS AND METHODS: We studied 207 patients between 1998 and 2007 at our hospital undergoing living-donor nephrectomy for kidney transplantation. The serum uric acid level and estimated glomerular filtration rate (eGFR) were measured preoperatively and at 1 year postoperatively. We also analyzed multiple independent variables such as age, sex, blood pressure, body mass index (BMI), serum total cholesterol, hemoglobin, hematocrit, total protein, albumin, calcium, and phosphorus. RESULTS: The mean age of the study patients was 38.3+/-10.8 years. The mean serum uric acid concentration at 1 year after kidney donation was higher than preoperatively (5.05+/-1.39 mg/dl preoperatively vs. 5.85+/-1.14 mg/dl postoperatively) and was significantly greater in patients with hyperuricemia (uric acid> or =6.8 mg/dl) than in patients without hyperuricemia (uric acid < 6.8 mg/dl): 1.63+/-0.75 mg/dl vs. 0.69+/-0.66 mg/dl, respectively. The multivariate analysis showed that preoperative serum uric acid was the primary predictive factor of postoperative serum uric acid (r=1.136, p=0.001), and preoperative GFR was an independent secondary predictive factor (r=-0.004, p=0.047). The receiver operator characteristics (ROC) curves for the preoperative serum uric acid cutoff of 5.7 mg/dl showed the highest sensitivity and specificity of 96% and 86%, respectively. CONCLUSIONS: These results suggest that preoperative serum uric acid and GFR were important predictive factors of postoperative serum uric acid after living-donor nephrectomy. Therefore, in the selection and management of kidney donors, not only patients with a low GFR but also those with high uric acid (serum uric acid > or =5.7 mg/dl) require careful observation before and after living-donor nephrectomy.

OBJECTIVE: The aim of this study is to evaluate the clinical usefulness of cervicogram as primary screening test of cervical intraepithelial neoplasia. METHODS: Total 294 women who had undergone cervicogram and pathologically diagnosed at YUMC between January and July 2003, were selected. Diagnostic accuracy of Pap smear, cervicogram and Pap smear combined with cervicogram were compared with pathologic diagnosis. Statistical analysis was performed by chi-square test (SPSS version 11.0). RESULTS: 1. Among 294 women, Pap smears were normal in 130 cases (44.2%) and abnormal in 164 cases (55.8%). The diagnostic accuracy between Pap smear and histology was as follows; sensitivity 72.0%, specificity 64.6%, positive predictive value 72.0%, negative predictive value 64.6%, false positive rate 28.0%, false negative rate 35.4%. 2. Cervicogram were normal in 202 cases (68.7%) and abnormal in 92 cases (31.3%). The diagnostic accuracy between cervicogram and histology was as follows; sensitivity 39.6%, specificity 79.2%, positive predictive value 70.7%, negative predictive value 31.0%, false positive rate 29.3%, false negative rate 49.0%. 3. Among 130 women with normal Pap smear, cervicogram were normal in 101 cases (77.7%) and abnormal in 29 cases (22.3%). The diagnostic accuracy between cervicogram with normal Pap smear and histology was as follows; sensitivity 26.1%, specificity 79.8%, positive predictive value 41.4%, negative predictive value 66.3%, false positive rate 58.6%, false negative rate 33.7%. 4. Among 164 women with abnormal Pap smear, Cervicograms were normal in 101 cases (61.6%) and abnormal in 63 cases (38.4%). The diagnostic accuracy between cervicogram with abnormal Pap smear and histology was as follows; sensitivity 44.9%, specificity 78.3%, positive predictive value 84.1%, negative predictive value 32.7%, false positive rate 15.9%, false negative rate 67.3%. CONCLUSION: Although adjunctive use of cervicogram to Pap smear in initial screening of cervical intraepithelial neoplasia showed higher specificity, higher negative predictive value and lower false negative rate compared to Pap smear alone, but, consideration in terms of lower sensitivity, lower positive predictive value, higher false positive rate and cost-effectiveness should be given in lieu of clinically applicating cervicogram with Pap smear as initial screening test.

Background: Cyclosporine (CsA), an immunosuppressant that specifically regulates T-lymphocytes, has long been used in dermatology practice. However, nephrotoxicity, a well-known adverse effect associated with high-dose (≥5 mg/kg/d) and long-term administration (≥2 years) has limited the use of CsA. Objective: We investigated the association between the cumulative dose of CsA and renal dysfunction, as well as the long-term effects of low-dose CsA on renal function in patients who presented with dermatological conditions. Methods: The study included 697 patients who received CsA at an outpatient dermatology clinic between January 2015 and May 2019. Logistic regression analysis was performed to determine the association between the cumulative dose of CsA and renal dysfunction. Results: Compared with patients who received the lowest cumulative dose (˂7,000 mg), those who received the highest cumulative dose of CsA (≥30,600 mg) showed a 64% higher risk of renal dysfunction; however, the difference was not statistically significant (odds ratio 1.64, 95% confidence interval 0.39∼6.84). Conclusion Among patients who receive a low-dose CsA regimen, those who are treated with cumulative doses higher than the critical value may be predisposed to renal dysfunction, whereas those treated with a cumulative dose lower than the critical value are unlikely to develop nephrotoxicity.

BACKGROUND: The assessment of the severity of psoriasis is often subjective because of the lack of quantitative laboratory diagnostic tools. Histopathological examination is the most commonly performed procedure for psoriasis diagnosis; however, it is usually descriptive. Thus, there is currently no quantitative method of determining psoriasis severity. The clinical types of psoriasis are correlated with the severity of the disease, and a lesional severity index, such as the psoriasis severity index (PSI), could be used as a quantitative tool for assessing gross severity. OBJECTIVE: To correlate the histopathological findings of psoriasis with the PSI. METHODS: Psoriatic lesions in 98 patients were evaluated. The lesions were classified into the guttate, papular, small plaque, and large plaque types according to morphology, and were scored according to the PSI. Ten common histopathological features of psoriasis were evaluated for correlation with gross severity. RESULTS: The clinical types of psoriasis showed significant correlations with the histopathological severity. However, the PSI score showed no correlation with histopathological severity. CONCLUSION: In the future, subjective gross assessment should be modified by using objective measuring devices with detailed scales, in order to correlate the findings with the histological severity.
