PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

The chest radiographs and angiograms were retrospectively evaluated in 47 patients with pulmonary atresia (PA) and ventricular septal defect (VSD) to determine the characteristic findings of major aortopulmonary collateral arteries (MAPCSs) on the chest radiographs. Of 47 patients, 23 had MAPCAs and 24 had only PDA for blood supply of whole right and left lung. Chest radiographs enabled identification of 16 of 23 patients with MAPCAs. The most common finding of MAPCAs was inappropriately large peripheral pulmonary vasculature (n=16, 69.6%). The other findings were tortuosity of pulmonary vasculature (n=12, 52.2%), focal unevendistribution of pulmonary vasculature (n=12, 52.2%), and two descending pulmonary arteries (n=4, 17.4%). When chest radiographs showed two or more findings of MAPCAs, MAPCAs could be differentiated from PDA with statistical significance (p<0.005). It is concluded that chest radiographs may help to identify MAPCAs before angiography if two-dimensional echo ardiography suggests PA with VSD.

PURPOSE: To evaluate quantification results of single breath-hold (SBH) magnetic resonance (MR) cine imaging compared to results of conventional multiple breath-hold (MBH) technique for left ventricular (LV) function in patients with cardiac arrhythmia. MATERIALS AND METHODS: MR images of patients with arrhythmia who underwent MBH and SBH cine imaging at the same time on a 1.5T MR scanner were retrospectively reviewed. Both SBH and MBH cine imaging were performed with balanced steady state free precession. SBH scans were acquired using temporal parallel acquisition technique (TPAT). Fifty patients (65.4 ± 12.3 years, 72% men) were included. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), myocardial mass, and LV regional wall motion were evaluated. RESULTS: EF, myocardial mass, and regional wall motion were not significantly different between SBH and MBH acquisition techniques (all P-values > 0.05). EDV, ESV, and SV were significant difference between the two techniques. These parameters for SBH cine imaging with TPAT tended to lower than those in MBH. EF and myocardial mass of SBH cine imaging with TPAT showed good correlation with values of MBH cine imaging in Passing-Bablok regression charts and Bland-Altman plots. However, SBH imaging required significantly shorter acquisition time than MBH cine imaging (15 ± 7 sec vs. 293 ± 104 sec, P < 0.001). CONCLUSION: SBH cine imaging with TPAT permits shorter acquisition time with assessment results of global and regional LV function comparable to those with MBH cine imaging in patients with arrhythmia.

Purpose: The robotic platform, an extension of minimally invasive procedures, is distributed nationwide and readily available. However, its application in inguinal hernia repair seems rare in Korea. This report aims to share our initial experience with robotic inguinal hernia repair. Methods: The patients who underwent robotic inguinal hernia repair by 2 different surgeons with different experiences at a single center were retrospectively analyzed. The surgical procedures were performed on all patients using the Da Vinci Xi robotic platform (Intuitive Surgical Inc). Patient demographics, operation variables, and postoperative outcomes were analyzed. Results: A total of 35 patients underwent robotic inguinal hernia repairs consecutively. The mean age was 55.03 ± 18.20 years. The majority of patients were male. The overall mean operation time was 103.98 ± 47.92 minutes for unilateral hernia surgery and 139.28 ± 46.07 minutes for bilateral surgery. None of the patients experienced intraoperative complications. However, postoperative complications were noticed in 8 patients: 3 with seroma formation, 1 with hematoma, 1 with superficial surgical site infection, and 3 with persistent pain at the operation site. Conclusion This report demonstrates an early experience of hernia surgery using the robotic platform. The robotic approach for transabdominal preperitoneal hernia repair was completed without any significant intraoperative or postoperative complications. It may be a viable option as a minimally invasive technique. Cost-effectiveness, optimal procedural steps, and indications for the robotic approach remain to be further investigated.

Purpose: Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used. Several dyes have been used for tattooing, but dye has disadvantages, including foreign body reactions. For this reason, we have used autologous blood tattooing for POC localization. This study aimed to evaluate the safety and efficacy of the autologous blood tattooing method. Methods: This study included patients who required POC localization of the colonic neoplasm among the patients who were scheduled for elective colon resection. The indication for localization was early colon cancer (clinically T1 or T2) or colonic neoplasms that could not be resected endoscopically. POC autologous blood tattooing was performed after saline injection, and 2 hemoclips were applied. Results: A total of 45 patients who underwent autologous blood tattooing and laparoscopic colectomy were included in this study. All POC localization sites were visible in the laparoscopic view. POC localization sites showed almost perfect agreement with intraoperative surgical findings. There were no complications like bowel perforation, peritonitis, hemoperitoneum, and mesenteric hematoma. Conclusion Autologous blood is a safe and effective agent for localizing materials that can replace previous dyes. However, a large prospective case-control study is required for the routine application of this procedure in early colon cancer or colonic neoplasms.

PURPOSE: We evaluated the capability of MR in the diagnosis of anomalous pulmonary venous connection (APVC). MATERIALS AND METHODS: The patient group consisted of 11 total APVC and 8 partial APVC diagnosed with MR. Echocardiography was performed in all cases, cardiac angiography in 12 cases and operation in 12 cases. We compared MR findings with those of operation, echocard iography and cardiac angiography. RESULTS: In surgically proven 12 cases, diagnostic accuracy of preoperative MR, echocardiography and cardiac angiography was 100%, 67% and 63%, respectively. In the remaining cases, MR findings well correlated with those of echocardiography or cardiac angiography. Stenosis of common pulmonary vein or superior vena cava was identified in 4 cases. In one patient, MR depicted associated cor triatriatum clearly. CONCLUSION: MR is an effective modallty in depicting anomalous pulmonary venous con nections.

PURPOSE: This study was conducted for the purpose of a structural model analysis of family health of women who came to Korea for being married to Korean men. METHODS: The data were collected from 260 immigrant women at multicultural centers located in C and B cities from May 10th to 30th, 2012. The variance analysis on the samples was conducted by using the maximum likelihood minimization function with AMOS 7.0. The fitness was evaluated by means of the SRMR, RMSEA, CFI, and TLI with a 90% confidence interval. RESULTS: First, immigrant women's self-esteem and acculturative stress were found to have significant direct effects on their family health. Second, their self-esteem and acculturative stress have direct effects on their marital adjustment. Third, their marital adjustment was found to have significant direct effects on their family health. Forth, immigrant women's Korean language ability was found not to have significant direct effects on their marital adjustment and family health. CONCLUSION: In order to enhance the family health of immigrant women, it is necessary to develop and apply nursing programs in consideration of immigrant women's self-esteem, marital adjustment and acculturative stress.

PURPOSE: To report the findings of a six-year medial oudit performed at our mammographic screening centre, comparing those findings with the follow-up data stored at our hospital and at the Korea Central Cancer Registry. MATERIALS AND METHODS: We analyzed the findings of 32,289 mammographic examinations of 25,541 women performed at our screening center between 1994 and 1999. For follow-up and outcome monitoring, the guideline of the American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) was used. All mammograms were categorized by means of BI-RADS, and cases in categories 0, 4, and 5 were followed up through a review of our hospital information system. To determine whether any cases were false negative, we compared breast cancer patients registered in our medical record department and in the Korean Central Cancer Registry during the study period, with women whose mammograms were interpreted as normal or benign at our screening center within a year prior to cancer diagnosis. RESULTS: The mean age of women enrolled in this study was 48.6 years, ten years less than reported in the West. The recall rate was 6.2%. Among 256 women whose final assessment category was 4 or 5, breast cancer was diagnosed in 51. The cancer detection rate was 2.0/1,000 women; positive predictive value 1 (PPV1: PPV, based on abnormal findings at screening examination) was 2.5% of cases and PPV2 (PPV when biopsy or surgical consultation was recommended) was 20%. The most common mammographic finding was microcalcifications only (45%). The rate of minimal breast cancer, including invasive cancer less than 1 cm in diameter and ductal carcinoma in situ, was 72.5%. Node positivity was 27%. Sensitivity was 85.0% based on the tumor registry of our institution's medical record department, and 78.5% based on the tumor registry of the Korea Central Cancer Registry. Specificity was 99.0%. CONCLUSION: In our study, the cancer detection rate at screening mammography was 2.0/1,000 women. The rate of minimal breast cancer (72.5%) was very high but measurable sensitivity was 78.5%, somewhat lower than the ACR guideline of 85%. To improve the performance of screening mammography, appropriate interpretation of mammography and constant, follow-up and outcome monitoring are important.
