Can the urine dipstick be used in the diagnosis of urinary bacterial colonizations in a preoperative urological assessment?

CONCLUSION: In spite of a good negative predictive value linked to a low prevalence of colonized patients (5%), the low sensitivity of the urine dipstick test entails a non-negligible number of false negatives. Its use as a single test of preoperative screening would expose colonized patients to the prospect of an operation, which seems to be unacceptable for some of them, notably endoscopic ones.

Here, we investigated omptin protease ‐mediated antimicrobial resistance among uropathogenicEscherichia coli clinical isolates. We found that clinical isolates with the highest omptin protease activity encode multiple omptin proteases, showing different substrate specificities. Our data suggest that the presence of multiple omptin family proteases in a single clinical isolate may provide a fitness advantage by expanding the range of natural antimicrobial peptides cleaved during urogenital tract colonization. AbstractBacterial colonization of the urogenital tract is limited by innate defenses, including the production of ...

Abstract Diabetes mellitus (DM) is a common disease in Oman as in rest of Gulf Cooperation Council where metabolic syndrome is of high prevalence. DM is a foremost risk factor for urinary tract infections (UTIs). It is also linked to more complicated infections such as emphysematous pyelonephritis (EPN), emphysematous pyelitis (EP), renal/perirenal abscess, emphysematous cystitis, xanthogranulomatous pyelonephritis, and renal papillary necrosis. The diagnosis of these cases is frequently delayed because the clinical manifestations are generic and not different from the typical triad of upper UTI, which include fev...

Urinary tract infections, including cystitis and pyelonephritis, are the most common bacterial infection primary care clinicians encounter in office practice. Dysuria and frequency in the absence of vaginal discharge and vaginal irritation are highly predictive of cystitis. Urine culture is recommended for the diagnosis and management of pyelonephritis, recurrent urinary tract infection, and complicated urinary tract infections. Antibiotics targeted toward Escherichia coli, Proteus, Klebsiella, and Staphylococcus saprophyticus are the recommended treatment. The duration of treatment varies by specific drug and type of infe...

In this study, we sought to establish a new, carefully optimized method to extract and purify non-denatured, native FliC from the reference UPEC strain CFT073 to be suitable for immune assays. To achieve purification of FliC to homogeneity, we used a mutant CFT073 strain containing deletions in four major chaperone-usher fimbriae operons (type 1, F1C and two P fimbrial gene clusters; CFT073Δ4). A sequential flagella extraction method based on mechanical shearing, ultracentrifugation, size exclusion chromatography, protein concentration and endotoxin removal was applied to CFT073Δ4. Protein purity and integrity ...

CONCLUSION: Currently, a second or third generation cephalosporin and amoxicillin-clavulanate are drugs of choice in the treatment of acute uncomplicated UTI. Parenteral antibiotic therapy is recommended for infants ≤ 2 months, and any child who is toxic-looking, hemodynamically unstable, immunocompromised, unable to tolerate oral medication, or not responding to oral medication. A combination of intravenous ampicillin and intravenous/intramuscular gentamycin or a third-generation cephalosporin can be used in those situations. Routine antimicrobial prophylaxis is rarely justified, but continuous antimicrobial prophylaxi...

The objective of this study was to investigate whether a single aminoglycoside dose adequately treated UTI.Methods: A systematic search of PubMed/MEDLINE and Google Scholar databases was performed through September 2018 for English-language original research articles assessing the efficacy of one-time parenteral aminoglycoside as UTI monotherapy.Results: Of 252 potentially relevant studies, 13 met inclusion criteria, representing 13,804 patients. Patient age ranged from 2 weeks to>70 years; both inpatient and outpatient settings were represented. Cystitis was more common than pyelonephritis and more females were represe...

Abstract Urinary tract infection (UTI) is a common infection seen in the emergency department. The spectrum of UTI includes simple versus complicated infection and lower versus upper UTI. No one history or examination finding is definitive for diagnosis. Testing often includes urinalysis and/or urine dipstick, and several pitfalls may occur in interpretation. Urine cultures should be obtained in complicated or upper UTIs but not simple and lower tract UTIs, unless a patient is pregnant. Imaging often is not required. Most patients with simple cystitis and pyelonephritis are treated as outpatients. A variety of pot...
