BACKGROUND: We evaluated the efficacy of two chemiluminescence immunoassays that detect treponemal antibodies, Centaur Syphilis and Immulite Syphilis, in comparison with Mediace Treponema pallidum latex agglutination (TPLA). METHODS: The study was conducted in two phases. In the first phase, we tested 1,147 serum samples that were sequentially submitted for routine syphilis serology. In the second phase, we tested a panel of 119 frozen serum samples that had previously tested positive by Mediace RPR. The kappa value, total agreement percentage, and sensitivity and specificity were analyzed. RESULTS: Of the 1,147 random samples, 24 (2.09%) tested positive with Centaur Syphilis, 16 (1.39%) with Immulite Syphilis, and 19 (1.66%) with Mediace TPLA. Of the 119 Mediace RPR-positive samples, 103 (86.6%) tested positive with Centaur Syphilis, 101 (84.9%%) with Immulite Syphilis, and 105 (88.2%) with Mediace TPLA. The percent agreements (kappa values) were 98.8% (0.934) between Centaur Syphilis and Mediace TPLA, 99.0% (0.94) between Immulite Syphilis and Mediace TPLA, and 99.2% (0.955) between Centaur Syphilis and Immulite Syphilis. To measure the sensitivity and specificity of each treponemal test, samples showing agreement in three or four of the tests (three treponemal tests and Mediace-RPR) were regarded as true positive (n=117) or true negative (n=1,142). The respective values for sensitivity and specificity were 100% and 99.6% for Centaur Syphilis, 98.3% and 100% for Immulite Syphilis, and 99.2% and 99.7% for Mediace TPLA. CONCLUSIONS: Results from the three treponemal assays were in good agreement. Greater sensitivity of Centaur Syphilis and greater specificity of Immulite Syphilis were suggested.

PURPOSE: Recently, vancomycin-resistant enterococci (VRE) have become one of the major nosocomial pathogens in Korea. However, there have been few studies on the epidemiology of VRE colonization among neonates. In this study, we investigated the prevalence of VRE colonization, risk factors for VRE, and how to control the spread of VRE infection in the Neonatal Intensive Care Unit (NICU) of Pusan National University Hospital (PNUH). METHODS: We retrospectively reviewed medical records of 192 neonates who were admitted to the NICU of PNUH from March 2006 to March 2007. Surveillance cultures from rectal swabs for detecting VRE were obtained weekly during the study period. We analyzed the prevalence of VRE and various risk factors. RESULTS: The rate of VRE colonization among NICU patients was 25% (48/192). Thirty five of these VRE colonized patients were transferred to the NICU from other local hospitals. Compared with the non-VRE group, the risk factors associated with VRE colonization were lower birth weight, congenital heart disease, applied mechanical ventilation, use of a central venous catheter, chest tubing, a history of surgery, and use of antibiotics. CONCLUSION: VRE colonization among patients admitted to the NICU is rapidly increasing. Monitoring and managing premature neonates from the beginning of the birth process, avoiding many invasive procedures, avoiding antibiotics such as vancomycin and third generation cephalosporin are important for preventing the emergence and spread of VRE colonization in the NICU.

Cisplatin has been widely used as chemotherapeutic agent for the treatment of cervical cancer, ovarian cancer, head and neck cancer and squamous cell carcinoma of lung. But cisplatin is highly toxic with nephrotoxicity, gastrointestinal toxicity, myelosuppression and neurotoxicity. The second generation drug of platinum compound, carboplatin was developed in 1980s to reduce side effects. Carboplatin has low nephrotoxicity but its major toxic effect is thrombocytopenia, In this study, the side effects of cisplatin and carboplatin were evaluated on 37 patients of cervical cancer in 169 chemotherpy cycles who were recieved combined VBP chemotherpeutic regimen consisting of cisplatin or carboplatin. Nephrotoxicity of grade 2 or over were 16% in cisplatin group and 1% in carboplatin group. Granulocytopenia of grade 2 or over were 34% in cisplatin group and 10% in carboplatin group. Thrombocytopenia of grade 2 or over were 7% in cisplatin group and 21% in carboplatin group. Gastrointestinal toxicity of grade 2 or over were 11% in cisplatin group and 0% in carboplatin group. This clinical study demonstrated that cisplatin has more toxic effects than carboplatin except thrombocytopenia.

BACKGROUND: The purpose is to determine the efficacy of additional intravenous patient-controlled analgesia (IV-PCA) by comparing the analgesic effects between interscalene block (ISB) combined with IV-PCA and single ISB after arthroscopic shoulder surgery. METHODS: A total of 213 patients who underwent arthroscopic shoulder surgery were divided into two groups based on the type of perioperative anesthesia. The single ISB group included 100 patients, while the IV-PCA group included 113 patients. The visual analogue scale for pain (VAS pain) scores were assessed at 12, 24, and 48 hours postoperatively in accordance with shoulder pathology. Postoperative narcotics-related complications and consumption of additional non-steroidal anti-inflammatory drugs between the two groups were compared. RESULTS: VAS pain showed no significant difference between the two groups at most points of the postoperative timeline, regardless of shoulder pathology, except in patients with rotator cuff repair at postoperative 24 hours. Although the IV-PCA group showed a statistically lower VAS pain score than the ISB group at postoperative 24 hours (p=0.04), the difference in the VAS pain score was only 9.0 mm in patients with rotator cuff repair. Narcotics-related complications were observed more frequently in the IV-PCA group than in the ISB group for patients with rotator cuff repair. CONCLUSIONS: Additional IV-PCA demonstrated no booster effect for immediate pain control in patients undergoing arthroscopic shoulder surgery with preoperative single ISB. Furthermore, patients with IV-PCA experienced greater narcotics-related complications.

PURPOSE:The incidence of glucose intolerance is increased in patients with Turner syndrome. Both noninsulin dependent diabetes mellitus and insulin dependent diabetes mellitus are increased. The purpose of this study was to investigate the impaired rate of carbohydrate metabolism in Turner syndrome after growth hormone treatment. METHODS:We investigated the incidence of carbohydrate intolerance and diabetes mellitus in 94 patients with Turner syndrome with NDDG and WHO criteria. The oral glucose tolerance test was performed in 78 patients. In 12 patients treated with growth hormone, the glucose tolerance test was performed before and after treatment. The insulin tolerance test was done in 20 patients. RESULTS:Only one patient had random plasma glucose level of more than 200 mg/dl. In results of the glucose tolerance test(n=78), 2 patients had glucose tolerance by NDDG criteria and 7 patients had it by WHO criteria. There was no change in glucose tolerance test results during growth hormone treatment. According to the results of the insulin tolerance test, we couldn't find any difference in insulin resistance between the growth hormone treatment group and the other treatments(oxandrolone, estrogen) group. CONCLUSION: The impaired rate of carbohydrate metabolism in Turner syndrome was much lower than in other reports. We observed that the impaired rate of carbohydrate metabolism did not increase after growth hormone treatment. However, the long-term effects in patients treated with growth hormone will be elucidated.

It has been proven that the newborn screening programs for congenital hypothyroidism are very important for its early detection and the early treatment of congenital It has been proven that the newborn screening programs for congenital hypothyroidism are very important for its early detection and the early treatment of congenital hypothyroidism can ameliorate and possibly reverse its consequences. Treatment with L-thyroxine is started in case of suspicious hypothyroidism at the first visit. Serum concentration of total and free thyroxine become normal within 1week after start of therapy but TSH values become normal from 2 months to 6 months after L-thyroxine therapy. The possible explanations for prolonged TSH elevation in congenital hypothyroidism are poor compliance for therapy, an inadequate dose of L-thyroxine, elevated threshold for thyrotropin suppression and two novel mutations in the thyrotropin (TSH) receptor gene in a child with resistance to TSH. Authors have experienced two cases of prolonged TSH elevation with normal T3 and T4 levels till 18months and 27 months of age after optimal L-thyroxine therapy and literature were reviewed.

10.Relationship between hs-CRP and HbA1c in Diabetes Mellitus Patients: 2015-2017 Korean National Health and Nutrition Examination Survey
Chonnam Medical Journal 2021;57(1):62-67
This study aimed to examine the relationship between hemoglobin A1c (HbA1c), one of the indicators of diabetes, and high sensitivity C-reactive protein (hs-CRP), one of the indicators of inflammation. Raw data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2015-2017) was analyzed. Among the patients diagnosed with diabetes, 1,479 adults were selected as subjects for our study, and their HbA1c levels, hs-CRP levels, sex, age, body mass index (BMI), waist circumference, level of triglycerides and high-density lipoprotein (HDL)-cholesterol, hypertension, receipt of diagnosis, monthly average income, education, and drinking and smoking habits were recorded. Multiple regression analysis of hs-CRP was performed by dividing hs-CRP into quartiles using HbA1c as the dependent variable. In Model 1, sex, age, and BMI were adjusted, and in Model 2, sex, age, BMI, waist circumference, level of triglycerides and HDL-cholesterol, hypertension, and receipt of diagnosis were adjusted. In Model 3, Model 2 parameters along with monthly average household income, education level, and drinking and smoking habits were adjusted. HbA1c levels increased as the hs-CRP quartile increased, that is, 2nd Quartile=0.307, p=0.003; 3rd Quartile=0.431, p=0.001; and 4 th Quartile=0.550, p=0.001. Of the various factors related to diabetes, this study examined the relationship between inflammation and diabetes.
