Recently, an increase in incidences of urinary tract infections in uncircumcised male infants has been reported. However, determining what is the best management for the prepuce of newborns and infants is still to be solved. I investigated prospectively how much foreskins are retracted with age and what correlations it has with urinary tract infection in 122 males children below 15 years of age. Under 6 months of age, the majority of the foreskins were unretractable. As they got older, over 3 years of age, their prepuces became retractable. The incidence of bacteriuria was 11.4% in uncircumcised but none in circumcised and hypospadias. In 8 patients showing bacteriuria, their foreskins were retracted below 25% in length. Among them, 5 patients, in whom E. coli were grown in their urine, showed radiologic renal abnormalities and suffered from high fever indicating systemic infection. However, the other 3 cases infected by Proteus mirabilis in their urine complained of only local penile symptoms.

The aim of this study was to demonstrate and assess C-reactive protein (CRP) changes in dogs with induced bacterial cystitis with or without antibiotics. We also evaluated availability of CRP levels to serve as an indicator for monitoring or diagnosing bacterial cystitis. Serial CRP concentrations in dogs with induced bacterial cystitis were higher than those of controls (p < 0.001). CRP concentrations peaked on day 7 and gradually decreased thereafter. In the treatment group, CRP concentrations decreased after medication compared to the untreated group (p = 0.032). CRP levels had a linear correlation with urine white blood cell counts among all groups (r = 0.837, p < 0.001, n = 140). Compared to the negative urine culture group, dogs with positive urine culture results had higher CRP concentrations (median 43.8 mg/L vs. 5.9 mg/L; p < 0.001). Area under the receiver operating characteristic curve was 0.955; when cut-off value was 12.2 mg/L, CRP measurements were found to have a sensitivity of 92.3% and specificity of 86.4%. This result indicates that rapid increases of CRP occurred after inducing bacterial cystitis and CRP may be a useful indicator for monitoring or diagnosing canine bacterial cystitis together with sediment urinalysis and urine bacterial culture.

OBJECTIVETo compare the antibacterial effects of Huangqin-Tang with its metabolites produced by intestinal flora.

METHODThe antibacterial tests in vitro and in vivo were performed by agar dilution method and lethal protection of animal respectively.

RESULTHuangqin-Tang and its metabolites had antibacterial action on bacteria in vitro, however the antibacterial activity of metabolites of Huangqin-Tang on Salmomella, Dysentery bacillus and Proteus in vitro was stronger than Huangqin-Tang. The metabolites of Huangqin-Tang had protective effect on the animals infected by Staphylococcus aureus and Escherichia coli respectively from death, but Huangqin-Tang had no lethal protection action.

CONCLUSIONThe antibacterial effects of metabolites of Huangqin-Tang in vitro and in vivo are stronger than that of Huangqin-Tang, which shows that intestinal flora play a very important role in antibacterial effects of Huangqin-Tang.

We investigated the occurrence and genetic basis of AmpC beta-lactamase (AmpC)-mediated antibiotic resistance, by examining Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis isolates at a university hospital, from 2007 to 2010. The ampC genes were detected by multiplex AmpC PCR, and AmpC-positive strains were subjected to DNA sequencing. Extended-spectrum beta-lactamase (ESBL) production was assessed using the ESBL disk test based on the utilization of boronic acid. Carbapenem-resistant isolates were further investigated by the modified Hodge test, a carbapenemase inhibition test and SDS-PAGE experiments. AmpC expression was detected in 1.6% of E. coli (39 DHA-1, 45 CMY-2, and 1 CMY-1) isolates, 7.2% of K. pneumoniae (39 DHA-1, 45 CMY-2, and 1 CMY-1) isolates, and 2.5% of P. mirabilis (8 CMY-2 and 1 CMY-1) isolates. Of the 198 acquired AmpC producers, 58 isolates (29.3%) also produced an ESBL enzyme. Among the acquired AmpC-producing K. pneumoniae isolates, the minimum inhibitory concentration (MIC) MIC50/MIC90 values for cefoxitin, cefotaxime, cefepime, imipenem, and meropenem were >32/>32, 16/>32, 1/16, 0.25/0.5, and <0.125/0.125 microg/mL, respectively. The MIC values for carbapenem were > or =2 microg/mL for 2 K. pneumoniae isolates, both of which carried the blaDHA-1 gene with a loss of OmpK36 expression, but were negative for carbapenemase production. The acquisition of AmpC-mediated resistance in K. pneumoniae isolates increased, as did the proportion of AmpC and ESBL co-producers among the hospital isolates. The accurate identification of isolates producing AmpCs and ESBLs may aid in infection control and will assist physicians in selecting an appropriate antibiotic regimen.
