Objective: The aim of this study is to describe the effects of Paljung-san on a patient with a catheter-associated urinary tract infection following a cerebral stroke. Methods: The patient was treated with herbal medicine (Paljung-san), and the effects of the treatment were evaluated using blood laboratory tests (C-reactive protein, erythrocyte sedimentation rate, and white blood cell count) and routine urine analysis. Results: After treatment, the patient's level of infection, as determined by the blood laboratory test and urine analysis, also improved. Conclusion: The results suggest that herbal medicine (i.e., Paljung-san) may be effective for treating catheter-associated urinary tract infections.

Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

Antenatal hydronephrosis (ANH) is one of the most common abnormal findings detected on prenatal ultrasound (US), and it has been reported in 1-5% of all pregnancies. The likelihood of significant postnatal pathologic abnormality in the urinary tract correlates with the degree of anterior-posterior diameter (APD) according to the gestational age. Detection of urologic anomalies prenatally permits fetal interventions that avoid complications in rare cases of bladder outlet obstruction with oligohydramnios even though their final benefits still remain controversial. There is no clear consensus on the extent and mode of postnatal imaging after a diagnosis of ANH. US is the mainstay of the postnatal evaluation and helps guide further testing with voiding cystourethrography (VCUG) and diuretic renography. Although most algorithms continue to recommend generous VCUG for identification of lower urinary tract anomalies, VCUG may be safely reserved for high grade ANH cases or any grade of ANH with dilated distal ureter without increasing the risk of urinary tract infection (UTI). There are conflicting studies about efficacy of postnatal prophylactic antibiotics. It still seems reasonable to consider use of a prophylactic antibiotic to prevent infant UTIs in high-risk populations, such as females and uncircumcised males with high grades of hydronephrosis, hydroureteronephrosis, or vesicouretral reflux.

Although asymptomatic bacteriuria, cystitis, and acute pyelonephritis (APN) have been categorized as urinary tract infections (UTIs), the immunopathogenesis of each disease is different. APN shows an age predilection; the majority of children (over 70-80%) with APN are under 1-2 years of age, with a male predominance. After 1-2 years of age, female predominance has been reported. This finding suggests that the immature immune state of infancy may be associated with the pathogenesis of APN. Escherichia coli is the most common etiologic agent; other uropathogens associated with UTIs originate from the host and comprise normal flora that are continuously altered by environmental factors. Therefore, uropathogens may have characteristics different from those of extraneous bacterial pathogens. Although antibiotic-resistant uropathogens, including extended-spectrum beta-lactamase-producing strains, are increasing in Korea and worldwide, treatment failure is rare in immune-competent children. The immunopathogenesis of APN remains unknown. Intact bacteria may not be the causative substances in renal cell injury; rather, smaller substances produced during bacterial replication may be responsible for renal cell injury and scarring. Moreover, substances from host cells such as proinflammatory cytokines may be involved in renal cell injury. A dimercaptosuccinic acid scan is used to detect the site of bacterial replication in the renal parenchyma, and may be influenced by the size of the focus and the stage of APN. Traditional aggressive studies used to identify vesicoureteral reflux after the first episode of APN have been modified because of rare cases of chronic kidney disease in patients with recurrent UTI.

This work describes a new strategy for optimal design of Multiplex-PCR primer sequences. The process is based on the Particle Swarm Optimization-Simplex algorithm (Mult-PSOS). Diverging from previous solutions centered on heuristic tools, the Mult-PSOS is selfconfigured because it does not require the definition of the algorithm's initial search parameters. The successful performance of this method was validated in vitro using Multiplex-PCR assays. For this validation, seven gene sequences of the most prevalent bacteria implicated in urinary tract infections were taken as DNA targets. The in vitro tests confirmed the good performance of the Mult-PSOS, with respect to infectious disease diagnosis, in the rapid and efficient selection of the optimal oligonucleotide sequences for Multiplex-PCRs. The predicted sequences allowed the adequate amplification of all amplicons in a single step (with the correct amount of DNA template and primers), reducing significantly the need for trial and error experiments. In addition, owing to its independence from the initial selection of the heuristic constants, the Mult-PSOS can be employed by non-expert users in computational techniques or in primer design problems.

Purpose: The purpose of this study was to find out lower urinary tract symptoms (LUTSs), self-management and quality of life (QOL) in middle aged men and to investigate how these factors are correlated with one another. Methods: The participants in this study were 217 men in G City. Data were collected using a questionnaire from October 23 to November 11, 2009. LUTSs were measured by IPSS, self-management by a self-management Likert scale, and QOL by the Korean-version WHOQOL-BREF. The collected data were analyzed through chi-square test, one-way ANOVA, and Pearson's correlation coefficient. Results: LUTS categories divided according to severity were none (10%), mild (57%), moderate (28%), and severe (5%). The mean score of self-management was 3.14 and that of QOL was 3.27. Self-management and QOL were significantly different according to LUTS. LUTS was negatively correlated with self-management and QOL. Self-management was positively correlated with QOL. Conclusion: In order to develop nursing interventions for middle aged men, comprehensive understanding of LUTS is needed.

Purpose: Urinary tract infections (UTIs) are the most common and serious bacterial infections in children. Therefore, early diagnosis of vesicoureteral reflux (VUR) for treatment planning and the identification of noninvasive markers that can predict renal injury are important in patients with UTIs. We analyzed the clinical features of pediatric UTIs commonly encountered by general practitioners and reinterpreted the blood tests and imaging findings to identify the important clinical predictive markers of VUR in order to selectively perform VCUG. Methods: This retrospective study was performed among 183 children diagnosed with a UTI or acute pyelonephritis. Results: The most significant predictor of high grade and bilateral VUR identified using area under the curve analyses was hydronephrosis on kidney ultrasound images with renal cortical defects on dimercaptosuccinic acid (DMSA) kidney scan simultaneously, followed by hydronephrosis only on kidney ultrasound. Conclusion: The presence of hydronephrosis on kidney ultrasound images or cortical defects or asymmetric kidneys on the DMSA kidney scans can be predictive markers of VUR, reducing the need for VCUG. Our study can thus help minimize the exposure to radiation among patients through selective VCUG.

In vitro activities of LB20304a were compared with those of grepafloxacin (OPC-17116), Q-35, ciprofloxacin, and sparfloxacin against 380 clinical isolates collected from general hospitals in 1996. LB 20304a was the most active agent against gram-positive strains including staphylococci, streptococci and enterococci. LB20304a was also very active against gram-negative bacteria and its activity was comparable to that of ciprofloxacin but better than those of grepafloxacin, Q-35 and sparfloxacin. The therapeutic effect of LB20304a was superior to those of sparfloxacin and ciprofloxacin against systemic infection by methicillin-resistant Staphylococcus aureus K283 (MRSA) in neutropenic mice. Against urinary tract infection induced by Escherichia coli 851E in mice, LB20304a was more active than sparfloxacin and ciprofloxacin. However, LB 20304a was slightly less active than that of ciprofloxacin against urinary tract infection by Pseudomonas aeruginosa 1912E, but better than that of sparfloxacin.

Shigella spp. cause classic bacillary dysentery that rarely result in extraintestinal complications. Urinary tract infections(UTIs) due to Shigella spp. are rare, and Shigella sonnei UTIs are extremely rare. We report a case of symptomatic UTI due to S. sonnei. A 9-year-old female presented with a history of fever, abdominal pain, loose form diarrhea, vomiting, and dysuria for 1 day. S. sonnei was identified from urine culture and stool culture result was no Salmonella and Shigella isolated. She was treated with gentamicin and cefuroxime intravenously for 5 days, which suscessfully controlled clinical features of infections.

Purpose: The purpose of this study was to investigate the degree of LUTS (Lower Urinary Tract Symptoms) and factors affecting LUTS in patients with prostate cancer. Methods: Fifty-four patients with prostate cancer participated and they completed a structured questionnaire at a hospital in Seoul. The LUTS level was measured by using the International prostate symptom score (1992) and the data were analyzed by Wilcoxon rank sum test and Kurskal-Wallis test. Results: Most subjects obtained a higher than moderate LUTS score. The participants who had a lower perceived health status and did not drink alcohol were more likely to had a lower LUTS score than other patients who had higher perceived health status and drink alcohol. In addition, eye diseases were significantly associated with the LUTS score. In LUTS, all the patients received higher IPSS-QOL (International prostate symptom score quality of life) and frequency, nocturia. Conclusion: For proper nursing care related to LUTS, nurses should focus on the factors identified when performing nursing assessments and should develop nursing intervention programs for symptoms management.
