Purpose: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. Methods: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. Results: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. Conclusion: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

Purpose: To implement evidence-based nursing, it is important to know where and how to find the best available evidence. This study was conducted to identify the results of a search from Ovid MEDLINE and to compare the results from Ovid MEDLINE with those from PubMed MEDLINE. Methods: Four different approaches via Ovid MEDLINE were used to search for guidelines on preventing catheter-associated urinary tract infections. Outcomes of this study were the number of records and relevant literature, and the sensitivity and precision of the search methods via Ovid MEDLINE. Results: The number of retrieved items ranged 23 to 6,005 and that of relevant studies, 5 to 8 of 8. Simple searches resulted in the highest sensitivity of 100.0%. When using MeSH terms and limits feature, the precision was highest (21.7%) among four approaches for literature searches. Simple searches in Ovid had higher sensitivity and lower precision than those in PubMed. Conclusion: Simple searches in Ovid may be inefficient for busy clinicians compared to PubMed. However, to ensure a comprehensive and systematic literature search, using Ovid MEDLINE in addition to PubMed is recommended.

This study was designed to investigate about the efficiency of herb treatment at the patients with urinary tract infection. The Patient group was consisted of 33 CVA patients who were diagnosed as abnormal on urinalysis at the Oriental Medical hospital of Dong-eui University from July in 2006 to April in 2007. And we divided the patient group to 3 of small groups(Bojungikitang, Kumokpaljungsan, and the others herb). Then we treated the patients with each herbs and checked urinary nitrate, leukocyte, bacteria, WBC after 3 days, 7 days. The results are as follows: Each herbs improved the results of urinalysis inspection. The efficiency of each herbs about UTI begins to be indicated after 3days. Each herbs applied to UTI is more effective after 7 days than after 3 days. As the results, the herb treatments improve effectively the result of urinalysis inspection when precsribing to UTI patients more 7 days.

A 10 days old male infant with congenital megacalyces and megaureter, diagnosed by prenatal ultrasonographic screening, underwent Tc-99m DTPA renal scan for evaluation of urinary tract patency, Tc-99m DMSA scan for evaluation of renal cortical damage. He also underwent intravenous urography(IVU) and renal ultrasonography. Tc-99m DTPA renal scan demonstrates intense tracer accumulation in enlarged both renal pelvocalyses and ureters, which rapidly washout without diuretics administration. Tc-99m DMSA renal cortical scan shows no remarkable photon defect in both renal cortices and visible tracer uptake in both megaureter areas. Ultasonographic and IVU studios show enlarged both renal calyses and bullously dilated ureters, but no dilatation in renal pelvis. Follow up Tc-99m DTPA renal scan, peformed at one year later, also reveals intense tracer accumulation in enlarged both urinary tracts which rapidly washout without diuretics, and shows no significant change compare to the previous Tc-99m DTPA renal scan. Urinary tract obstruction and renal cortical damage can be easily evaluated with Tc-99m DTPA and Tc-99m DMSA scans in patiens with megacalyces and megaureter.

Purpose: Microalbuminuria is defined as increased urinary albumin excretion (30-300 mg/day) or microalbumin/creatinine ratio (30-300 mg/g) in a spot urine sample. Although microalbuminuria is a predictor of clinical nephropathy and cardiomyopathy, few studies have investigated microalbuminuria in children with urinary tract infection (UTI). Therefore, we compared the spot urine microalbumin/creatinine ratio in pediatric UTI patients with that of control subjects. Methods: We investigated the correlation between the ratio in children with UTI and age, height, weight, blood pressure, glomerular filtration rate (GFR), hematuria, vesicoureteral reflux, renal parenchymal defect, and renal scar, and its predictability for UTI complications. Results: We studied 66 patients (42 boys, 24 girls) and 52 healthy children (24 boys, 28 girls). The mean microalbumin/creatinine ratio in UTI patients was statistically significantly increased compared to the control group ($340.04{\pm}321.36mg/g$ vs. $225.68{\pm}154.61mg/g$, $P$=0.0141). The mean value of spot urine microalbumin/creatinine ratio ($384.70{\pm}342.22mg/g$ vs. $264.92{\pm}158.13mg/g$, $P$=0.0341) in 1-23 months age patient group showed statistically significant increase compared to control group. Microalbumin/creatinine ratio showed negative correlation to age (r=-0.29, $P$=0.0167), body surface area (BSA) (r=-0.29, $P$=0.0173) and GFR (r=-0.26, $P$=0.0343). The presence of hematuria ($P$=0.0169) was found to be correlated. Conclusion: The spot urine microalbumin/creatinine ratio in children with UTI was significantly greater than that in normal children, and it was positively correlated with GFR. This ratio is a potential prescreening and prognostic marker in UTI patients. Further studies are required to validate the predictability of microalbuminuria in pediatric UTI patients.

Purpose: To investigate the association between urinary neutrophil gelatinase-associated lipocalin (uNGAL) and leukocyte differential count in children with urinary tract infections (UTIs). Methods: A retrospective chart review was performed in children undergoing uNGAL measurements between June 2018 and September 2019. Patients with suspected or diagnosed UTIs were included. The relationship between uNGAL and blood leukocyte differential count was investigated in children. Results: A total of 197 children were included in this study, 119 of whom (60%) had UTIs. The non-UTI patients (n=78) were diagnosed with pneumonia, acute gastroenteritis, viral upper respiratory infection, and others. After adjusting for age, gender, and fever duration, the leukocyte count, monocyte count, and uNGAL levels were higher in the UTI group than in the non-UTI group (P<0.05). uNGAL showed positive correlations with neutrophil counts, monocyte counts, the neutrophil-to-lymphocyte ratio, and the monocyte-to-lymphocyte ratio in the UTI group (P<0.05). uNGAL levels were only associated with the neutrophil-to-lymphocyte ratio in the non-UTI group (P<0.05). In a multivariable logistic regression analysis, only uNGAL was associated with the presence of UTI (P<0.05). The area under the receiver operating characteristic curves for uNGAL and monocyte counts to identify UTI were 0.89 (95% confidence interval (CI): 0.824-0.939; P=0.025) and 0.7 (95% CI: 0.627-0.774; P=0.038), respectively. Conclusions: In children with UTIs, uNGAL levels may be associated with blood leukocyte differential counts. uNGAL measurements and monocyte counts can be helpful in children with suspected UTIs.

목 적 : 요로 감염은 소아에서 흔한 세균성 감염 질환이다. 특히 영아나 어린 소아에서의 감염은 수신증이나 방광 요관 역류와 같은 요로의 동반 기형과 관련성이 높다. 이 연구의 목적은 영아와 어린 소아에서 E. coli 에 의한 요로 감염과 E. coli 외의 다른 균에 의한 요로 감염사이의 임상소견과 검사실 소견, 요로계 영상 검사 소견을 비교해 보는 것이다. 방 법 : 2003년 1월부터 2005년 12월까지 부산 일신 기독 병원 소아과에 요로감염으로 입원한 170명의 환아들의 임상 기록을 후향적으로 분석하였다. 모든 환아들은 E. coli 요로 감염과 non-E. coli 요로 감염의 두 그룹으로 나뉘었고 각각의 인구학적 자료, 임상 자료(발열 정도와 기간, 해열 기간, 입원 기간), 요로계 동반 질환(병력과 초음파를 통해)과 감염의 재발(병력과 과거 의무 기록을 통해), 검사실 소견[요 침사 현미경 검사, 말초혈액 백혈구 수, 적혈구(ESR), CRP, 혈청 크레아티닌 수치]을 비교하였다. 결 과 : 요로 감염으로 진단된 170명의 환아 중 114명(67.1%)은 E. coli에 의한 요로 감염이었고 나머지 56명(32.9%)은 다른 요로 감염 균에 의한 감염이었다. Non-E. coli 그룹은 E. coli 그룹에 비해 발병 연령이 더 낮고($0.52{\pm}0.59$세 vs $0.84{\pm}1.39$세, P<0.05), 요로 기형의 동반률이 높고[46례(82.1%) vs 53례(46.5 %), P<0.001], 재발률이 높고, 해열까지의 기간이 더 짧으며, 말초혈액 백혈구수가 더 적고, CRP 수치가 더 낮고, ESR 수치가 더 낮다. 결 론 : Non-E. coli 요로 감염은 E. coli 요로 감염에 비해 발병 연령이 더 어리고, 경한 임상 양상과 검사실 소견을 보이며, 요로 기형의 동반률이 높고 재발률도 높다.
