Purpose: Catheter urine (CATH-U) and suprapubic aspiration (SPA) are reliable urine collection methods for confirming urinary tract infections (UTI) in infants. However, noninvasive and easily accessible collecting bag urine (CBU) is widely used, despite its high contamination rate. This study investigated the validity of CBU cultures for diagnosing UTIs, using CATH-U culture results as the gold standard. Methods: We retrospectively analyzed 210 infants, 2- to 24-month-old, who presented to a tertiary care hospital's pediatrics department between September 2008 and August 2013. We reviewed the results of CBU and CATH-U cultures from the same infants. Results: CBU results, relative to CATH-U culture results (${\geq}10^4$ colony-forming units [CFU]/mL) were widely variable, ranging from no growth to ${\geq}10^5CFU/mL$. A CBU cutoff value of ${\geq}10^5CFU/mL$ resulted in false-positive and false-negative rates of 18% and 24%, respectively. The probability of a UTI increased when the CBU bacterial count was ${\geq}10^5/mL$ for all infants, both uncircumcised male infants and female infants (likelihood ratios [LRs], 4.16, 4.11, and 4.11, respectively). UTIs could not be excluded for female infants with a CBU bacterial density of $10^4-10^5$ (LR, 1.40). The LRs for predicting UTIs based on a positive dipstick test and a positive urinalysis were 4.19 and 3.11, respectively. Conclusion: The validity of obtaining urine sample from a sterile bag remains questionable. Inconclusive culture results from CBU should be confirmed with a more reliable method.

Purpose: The purpose of this study was to identify the risk factors for a nosocomial urinary tract infection in intensive care units with a foley catheterization which showed a positive urine culture. Method: Three-hundred eighty-seven patients were included in the study. A retrospective review of the electrical medical record system's databases and medical record sheets in hospitalized patients from January 2003 to December 2003 was used. The collected data was analyzed by descriptive statistics, t-test, chi-square test and logistic regression analysis. Result: The frequency of the participants' nosocomial urinary tract infection was 72.9%. Significant risk factors for a nosocomial urinary tract infection were 'age', 'place of catheter insertion', 'frequency of catheter change', and 'duration of catheterization'. These variables explained 18.4% of variance in the experience of nosocomial urinary tract infection in intensive care units with foley catheterization. Conclusion: Medical personnel can decrease the incidence of a nosocomial urinary tract infection by recognizing and paying attention to the duration of catheterization, frequency of catheter change, and place of catheter insertion. As a result, specific and scrupulous strategies should be developed to reflect these factors for decreasing nosocomial urinary tract infections.

Purpose: This study was designed to verify effects of perineal care with aroma essential oil on urinary tract infection(UTI) in patients with indwelling urinary catheter. Method: The research design was non equivalent control group pretest-post test design. The data were collected from March to August, 2005 at C university hospital in Seoul. The subjects were 43 patients who had a indwelling catheter in neurosurgery intensive care unit(NSICU). They were assigned to two groups, 21 subjects to the experimental group and 22 subjects to the control group. The experimental group received perineal care with 3% blending essential oil for 4 days. Results: In the experimental group, white blood cells and bacteria in urine were significantly lower than control group. Bacteria in urine culture was lower in the experimental group at post test. Conclusion: Perineal care with aroma essential oil could be an effective intervention to reduce the UTI of patients in NSICU.

Purpose: Burkholderia cepacia is an aerobic, glucose-non-fermenting, gram-negative bacillus that mainly affects immunocompromised and hospitalized patients. Burkholderia cepacia has high levels of resistance to many antimicrobial agents, and therapeutic options are limited. The authors sought to analyze the incidence, clinical manifestation, risk factors, antimicrobial sensitivity and outcomes of B. cepacia urinary tract infection (UTI) in pediatric patients. Methods: Pediatric patients with urine culture-proven B. cepacia UTI between January 2000 and December 2014 at Samsung Medical Center, a tertiary referral hospital in Seoul, Republic of Korea, were included in a retrospective analysis of medical records. Results: Over 14 years, 14 patients (male-to-female ratio of 1:1) were diagnosed with B. cepacia UTI. Of 14 patients with UTI, 11 patients were admitted to the intensive care unit, and a bladder catheter was present in 9 patients when urine culture was positive for B. cepacia. Patients had multiple predisposing factors for UTI, including double-J catheter insertion (14.2%), vesico-ureteral reflux (28.6%), congenital heart disease (28.6%), or malignancy (21.4%). Burkholderia cepacia isolates were sensitive to piperacillin-tazobactam and sulfamethoxazole-trimethoprim, and resistant to amikacin and colistin. Treatment with parenteral or oral antimicrobial agents including piperacillin-tazobactam, ceftazidime, meropenem, and sulfamethoxazole-trimethoprim resulted in complete recovery from UTI. Conclusion: Burkholderia cepacia may be a causative pathogen for nosocomial UTI in pediatric patients with predisposing factors, and appropriate selection of antimicrobial therapy is necessary because of high levels of resistance to empirical therapy, including aminoglycosides.

This case study reports on the effect of Korean medicine on a catheter-associated urinary tract infection (CAUTI) caused by multidrug-resistant Pseudomonas aeruginosa. An 83-year-old man diagnosed with stroke had dysuria, and it was found that an indwelling urinary catheter led to CAUTI. From laboratory tests, we identified multidrug-resistant Pseudomonas aeruginosa and applied Korean medicine to him. After herbal medication with acupuncture and moxibustion, we studied a urinalysis and urine culture again for follow-up. We found meaningful improvement in bacteriuria and bacterial identification. This case suggests that Korean medicine could have a beneficial effect on urinary tract infections caused by multidrug-resistant Pseudomonas aeruginosa.

Streptococcus agalactiae or group B streptococcus (GBS) is associated with infections in neonates and pregnant women. Herein, we describe a rare case of GBS renal abscess with peritonitis and pleural effusion in a 17-year-old girl with type 1 diabetes mellitus. The girl was admitted due to fever and right flank pain. Laboratory findings included leukocytosis and increased C-reactive protein level and erythrocyte sedimentation rate. Her serum glucose level was 484 mg/dL. Urinalysis showed no pyuria. Renal sonography revealed parenchymal swelling in the right kidney. The patient was administered intravenous cefotaxime. Urine and blood cultures were negative. Fever seemed to improve, but the following day, she complained of abdominal pain and fever. Antibiotic was switched to imipenem, and abdominal and pelvic CT revealed a ruptured right renal abscess, peritonitis, and bilateral pleural effusion with atelectasis. Pigtail catheter drainage of the abscess was performed. Culture from the abscess was positive for GBS, and fever subsided 2 days after the drainage. She was discharged with oral cefixime. The clinical course of urinary tract infections (UTIs) can be atypical in patients with diabetes, and GBS can be a cause of UTIs. Prompt diagnosis and management are necessary to prevent complications in patients showing atypical courses.

Infection is one of the main causes of death in severe burn cases. Treatment of burn patient includes fluid therapy, wound care, complication care and antibiotic therapy for infection. The objective of this study was to evaluate the characteristics of burn patients, the type of isolated microorganisms and their susceptibility, and the systemic antibiotics used. This is a retrospective study of 126 burn patients treated in the Hanil General Hospital from January to December 2001. Total 126 patients were assessed with 103 males and 23 females (4.5:1). The average age was $34.8\pm17.6$ years and extent of burn $(TBSA\;\%)\;was\;24.5\pm18.5\%$. The burn was caused by electric accident $(47.6\%),\;flame\;(29.4\%),\;scalding\;(21.4\%),\;and\;chemical\;accident\;(1.6\%)$. The overall mortality rate was $7.14\%$ (9/126) and all expired patients were males. The average age (n=9) was $48.8\pm15.6$ yrs and the extent of burn was $65.0\pm19.0\%$. The causes of death were due to flame burns $(13.5\%)$ and electric burns $(6.7\%)$. The culture sites of the isolated microorganisms were wound $(85.3\%),\;sputum\;(9.3\%),\;urine\;(2.7\%),\;blood\;(1.3\%)\;and\;catheter\;tip\;(1.3\%)$. Pseudomonas aeruginosa was the most commonly isolated organism $(35\%)$, followed by Staphylococcus aureus $(30.1\%)$, Acinetobacter baumannii $(21.4\%)$, and Enterococcus spp. $(3.9\%)$. The number of systemic antibiotics administered was 4.5. The classes of the antibiotics were cephalosporines $(38.5\%)$, aminoglycosides $(31\%)$, quinolones $(13.3\%)$, penicillins $(12.4\%)$, carbapenems $(2.4\%)$, glycopeptides $(1.9\%)$ and others $(0.6\%)$. In conclusion, most of burn patients had wound infection and Pseudomonas aeruginosa was the most commonly isolated organism. Cephalosporins were administered the most frequently among antibiotics.

목적 : 발열을 동반한 소아요로 감염 환아에서 조기진단과 신속한 치료는 신손상을 예방한다는 점에서 매우 중요하다. 요분석은 성인 요로 감염의 선별검사로서 가치가 있는 것으로 보고되고 있지만 소아에서는 연령에 따라 상반된 보고도 있다. 이에 저자들은 발열을 주소로 내원하여 뇨 배양검사상 요로감염증으로 진단된 환아를 대상으로 요분석과 신영상 소견을 평가하고자 한다. 방법 : 1996년 9월부터 1998년 8월가지 서울위생병원 소아과에 발열을 주소로 입원한 소아 환아에서 무균 채취 주머니, 중간뇨, 방관 요관 카테터법 및 방광 천자에 의한 요배양 검사에 의해 요로 감염으로 확진된 56명의 환아를 대상으로 Dipstick 요분석(Leukocyte esterase, nitrite)과 요침사 검사(농뇨 및 Gram 염색하지 않은 현미경상 세균관찰)와 신영상 검사 소견을 비교하였다. 결과 : Dipstick 요분석상 요로감염 환아의 Leukocyte esterase(LE)양성율은 54%(30/56), Nitrite 양성율은 36%(20/56), LE 또는 Nitrite 양성율은 68%(38/56)로 관찰되었다. 요침사 검사상 요로감염 환아의 백혈구 양성율은 68%(38/56), 세균양성율은41%(23/56), 백혈구 또는 세균 양성율은 73%(41/56)로 관찰되었다. 요로감염 환아에서 Dipstick 요분석과 요침사 검사에서 모두 음성을 보였던 경우는 18%(10/56)였다. DMSA 신주사에서 신반흔을 보인 24례(43%)의 요로감염 환아 중 Dipstick 요분석상 양성율은 71%(17/24), 요침사 검사상 양성율은 83%(20/24)였으며 신 주사에서 정상소견을 보인 32례(57%)의 요로감염 환아 중 Dipstick 요분석상 양성율은 66%(21/32), 요침사 검사석상 양성율은 66%(21/32)로 신반흔을 보인 군에서 요침사 검사상 양성율이 높게 나왔지만 통계학적으로 의미있지는 않았다(P=0.117). 배뇨중 방광 요도 조영술을 시행한 18례의 요로감염 환아 중 7례에서 요관 역류를 확인할 수 있었다. 요관 역류를 보인 군과 요관 역류를 보이지 않은 군에서 요분석상 의미 있는 차이는 없었다. 결론 : 요로감염 소아에서 신 반흔 및 방광 요관 역류와 요분석의 관계는 신반흔이 있었던 경우 요침사 검사가 약간 높게 나왔지만 통계학적으로 의미있게 나타나지는 않았다.
