PURPOSE: Urinary tract infection (UTI) is an ascending infection of fecal uropathogens, urogenital lactobacilli are suggested to play a role in the prevention of UTI. This study was to investigate whether lactobacillus mixture (LM) could prevent the experimental infantile UTI. MATERIALS AND METHODS: The LM were composed of three lactobacillus strains (L. gasseri, L. rhamnosus, and L. reuteri). Mother rats were grouped as lactobacillus (LB) group I (LB I, n=22), II (LB II, n=24) and control (n=20). LB I and LB II were fed with LM (1 mL/day) and control with phosphate-buffered saline (PBS) from late pregnancy through lactation. All newborn rats were breast-fed and their urine and stool were collected at the end of the 3rd week to compare lactobacillus colony. Then, infant rats from LB II were treated with intravesical instillation of LM. Infant rats from LB I and control were instilled with PBS. Twenty-four hours later, experimental UTI was introduced by intravesical instillation of standard E. coli strain. After 72 hours later, the infant rats were sacrificed for histologic examination. RESULTS: Lactobacilli colonies in urine and stool were not statistically different among the three groups. The incidence of pyelonephritis in the LB II was 16.7% (4/24), LB I 72.7% (16.22) and control 75.0% (15/20) (p=0.015). The incidence of cystitis was not significantly different among the three groups. CONCLUSION: The intravesically instilled LM significantly prevented experimental pyelonephritis in infant rats, however, LM administered orally to the pregnant and lactating mother rats did not.

OBJECTIVETo discuss the effect and safety of preventive administration of antibiotics to patients with benign prostatic hyperplasia (BPH) before urodynamic examination.

METHODSA total of 256 BPH patients to undergo urodynamic examination were randomly divided into a control group (n = 118) and a trial group (n = 138). The former received no pre-treatment while the latter were given cefoxitin sodium iv at 1.0 g 30 minutes before complete urodynamic examination. Then we compared the incidence rates of urinary tract infection between the two groups.

RESULTSStatistically significant differences were found in the incidence rate of urinary tract infection between the control and trial groups (20.3% [24/118] vs 7.3% [10/138], P < 0.01), as well as in those with diabetes mellitus (6.7% [3/45] vs 23.5% [8/34], P < 0.05), those with residual urine > 50 ml (5.4% [3/56] vs 18.5% [10/54], P < 0.05), and those with both diabetes mellitus and residual urine (9.5% [2/21] vs 44.4% [8/18], P < 0.05). Only 3 patients (2.2%) in the trial group had mild adverse drug reactions.

CONCLUSIONFor BPH patients, particularly those with diabetes mellitus and residual urine, preventive administration of antibiotics before urodynamic examination is safe and can effectively protect the patients against urinary tract infection.

Increasingly accumulated results from randomized controlled trials and other clinical studies have demonstrated that male circumcision reduces the risks of acquisition and transmission of HIV, HPV, HSV-2, and other sexually transmitted infections, and thus has a potential role in preventing cervical cancer, penile cancer and prostate cancer. The prevalence of male circumcision in China is currently less than 5%. The clinical evaluation studies and randomized controlled trials of the Shang Ring device showed excellent safety profiles, extremely high acceptability, and satisfaction among the participants and service providers in Africa and China. Given the recent recommendations by the World Health Organization and the Joint United Nations Program on HIV/AIDS (UNAIDS), voluntary medical male circumcision should be promoted in China at the national level as an important alternative intervention to reduce reproductive tract infections and prevent both males and females from reproductive tract cancers. More emphasis is required on the studies of the long-term health benefits of male circumcision in uro-andrology.

PURPOSE: This study compared the catheter-associated urinary tract infection (CAUTI) rates resulting from the use of four perineal care agents (soap-and-water, skin cleansing foam, 10% povidone-iodine, and normal saline) among patients in intensive care units (ICUs). METHODS: This four-group experimental study was done with 97 adult patients who had urinary catheters over 2 days in three ICUs between April and July 2008. The patients received one of the four types of perineal care. Data collected included the incidence of CAUTI at baseline (prior to perineal care) and 1 week, 2 weeks, and 4 weeks after beginning perineal care. Patients were divided into UTI and non-UTI groups based on the Centers for Disease Control and Prevention/National Healthcare Safety Network UTI definition to calculate incidence rates. The hazard ratio (HR) and 95% confidence intervals were calculated by Cox's proportional hazard analysis. RESULTS: The cumulative incidence of CAUTIs per 100 urinary catheter days were 3.18 episodes during 1 week with urinary catheter, 3.31 during 2 weeks, and 3.04 during 4 weeks. No statistically significant difference in hazard ratios of CAUTIs for each perineal care agent was evident with reference to soap-and-water at 1 week, 2 weeks, and 4 weeks after beginning perineal care after controlling for age, use of antibiotics, fecal incontinence, consciousness level, fever, and diabetes. CONCLUSIONS: The type of perineal care does not influence the incidence of CAUTIs. Further confirmatory studies with a larger patient population should be conducted, as well as determining perineal agent preference.

BACKGROUND: Vancomycin-resistant enterococci (VRE) have been important pathogen of nosocomial infections and isolated most commonly from urine specimens. However, the clinical significance of VRE bacteriuria remains unknown. The objectives of this study are to describe the frequency, related factors and outcomes of VRE bacteriuria, and to compare epidemiologic data and outcomes between the subgroups: symptomatic urinary tract infection (UTI), asymptomatic bacteriuria, and colonization. MATERIALS AND METHODS: For patients with urine culture positive for VRE between August 1, 2002 and June 30, 2005, we collected clinical data and performed a retrospective analysis. According to Centers for Disease Control and Prevention (CDC), patients were classified as symptomatic UTI, asymptomatic bacteriuria, colonization and undetermined. RESULTS: Total 144 episodes (2.88%), in 58 patients, of 5,008 urine specimens were positive for VRE during the study period. Frequency of antimicrobial exposure history, especially 3rd generation cephalosporin, indwelling urinary catheter, and ICU stay at the time of culture was high in patients with VRE bacteriuria. In VRE bacteriuria, symptomatic UTI was only 24.5%. Instead the majority of the patients (71.4%) was colonized in urine with VRE or had asymptomatic bacteriuria. In comparison between symptomatic UTI group and combined group of asymptomatic bacteriuria and colonization, most demographic data and clinical features including hospital day and mortality had no significant difference except one, male sex. CONCLUSION: Most patients with VRE bacteriuria were classified as asymptomatic bacteriuria and colonization and only one-fourth of patients with VRE bacteriuria require antibiotic therapy. Therefore, clinicians should decide to initiate antibiotic therapy after consideration of clinical significance of VRE bacteriuria.

OBJECTIVETo explore the correlation between single acupoints used and the recurrence rate of cystitis among cystitis-prone women receiving acupuncture as a prophylactic treatment.

METHODSIn all, 58 cystitis-prone women were included in the analysis. Customised acupuncture treatments were given twice a week, over 4 weeks. The main effect parameter was the number of cystitis episodes during the 6-month observation time. Residual urine was measured at baseline, 2, 4 and 6 months using portable ultrasound equipment. Sympathetic and vagotone nerve activities were measured by using skin conductance and respiratory sinus arrhythmia, respectively.

RESULTSThe main acupoints used for patients with Kidney (Shen) qi/yang deficiency were Shenshu (BL23), Taixi (KI3), Zhongji (CV3), Sanyinjiao (SP6) and Pangguangshu (BL28), compared with Taichong (LR3), CV3, BL28, Yinlingquan (SP9) and SP6 for Liver (Gan) qi stagnation, and SP6, CV3, BL28, Zusanli (ST36) and SP9 for Spleen (Pi) qi/yang deficiency patients. The combination BL23 and KI3 were used in 16 women, 13 of which were Kidney pattern related patients. When used, the number of symptomatic episodes were reduced to a third compared with what occurred in the 42 women where this combination was not used (3/16 vs. 28/42, P<0.05). BL23 application correlated to a significant reduction in residual urine measured a few days after treatment. Patients with the pattern of Spleen qi/yang deficiency had an initial increase in residual urine after treatments.

CONCLUSIONTreating Kidney pattern related patients with the combination of BL23 and KI3 resulted in far better outcome than other points/combination of points for other Chinese medicine diagnoses. The acupoint SP6 may be less indicated than previously assumed when treating cystitis-prone women prophylactically.

OBJECTIVETo observe the effect of reducing the incidence of CAUTI by spraying the long-acting antibacterial material JUS on the surface of catheter and urethral orifice.

METHODSSixty male patients, aged from 68 to 79, with indwelling catheter after TURP were divided randomly into two groups (control group and treated group), each consisting of 30 patients. For the control group, their urethral orifice was treated conventionally twice a day; while for the treated group, in addition to the conventional treatment of their urethral orifice, the catheter and their urethral orifice were sprayed with the long-acting antibacterial material JUS twice a day.

RESULTThe number of cases of urinary tract infection in the treated group during catheterization was evidently less than those of the control group (P < 0.01), so the difference was of remarkable significance.

CONCLUSIONThe long-acting antibacterial material, after spraying on the wall of catheter and urethral orifice of the patients with indwelling catheter, may form a layer of physically antibacterial molecular film to prevent the formation of a bacterial biological film and effectively reduce the incidence of CAUTI.

Stroke ranks as one of the leading causes of death and the most common cause of permanent disability in adults in Korea. Timely recognition and treatment is imperative to reduce stroke-related morbidity and mortality. Patients with acute ischemic stroke should be evaluated for intravenous thrombolysis with recombinant tissue-plasminogen activator (rt-PA); antiplatelet drugs can be administered to those who do not qualify for rt-PA therapy. Adequate hydration and correction of possible hypoxia are necessary, and hyperglycemia and fever should be treated aggressively. Blood pressure management should be individualized on the basis of stroke pathophysiology. It is important to prevent and manage complications of acute stroke, such as pneumonia, urinary tract infection, bed sore, deep vein thrombosis, and joint contracture. Meticulous evaluation of etiology of ischemic stroke can determine the most appropriate acute management and would guide the secondary prevention of stroke.

OBJECTIVETo study the preventive effect of herbal formulation on experimental murine urinary tract infection (UTI) induced by Dr Escherichia coli 11128.

METHODSE. coli 11128 carrying Dr fimbriae was isolated from patients with chronic pyelonephritis. The minimal inhibitory concentration (MIC) value of herbal solution for E. coli 11128 was determined for further studies. Forty C3H/HeJ mice were divided into the herb-treated group (n=20, given Chinese herbs by gavage at an average dose of 20 g/kg body weight daily 3 days before inoculation), and control group (n=20, given the same amount of distilled water by gavage). Three and 6 days after infection, bacteria were counted in the urine and the kidneys of the mice. Kidney histopathologic changes were evaluated. Neutrophils infiltration and accumulation were detected.

RESULTSThe MIC value of herbal solution was 0.1 g/mL for the E. coli 11128. In herb-treated mice, there was a significant reduction in bacterial counts in urine and colonization densities of kidneys. Microscopic studies revealed signs of inflammation in kidneys. In herb-treated mice, herbal administration resulted in significantly reduced neutrophilic infiltrates (P<0.05). The semi-quantitative scores for renal lesions were significantly lower (P<0.05).

CONCLUSIONProphylactic administration of herbal formulation potentiated the effect in partially preventing experimental murine ascending UTI.
