Bifidobacterium species are difficult to identify and may be underreported or not recovered by many laboratories because of their slow growth. We emphasize the importance of the Gram stain in urine samples and the addition of enriched media and enhanced atmosphere over time for urine cultures with pyuria. This is the first report of a Bifidobacterium scardovii recurrent urinary infection in an ...

Microbiological confirmation of a urinary tract infection (UTI) takes 24-48 h. In the meantime, patients are usually given empirical antibiotics, sometimes inappropriately. We assessed the feasibility of sequentially performing a Gram stain and MALDI-TOF MS mass spectrometry (MS) on urine samples to anticipate clinically useful information. In May-June 2012, we randomly selected 1000 urine samp...

OBJECTIVE To review systematically and to summarize the existing literature regarding performance of rapid diagnostic tests for urinary tract infection (UTI) in children. DESIGN Systematic review and meta-analysis. METHODS Published articles reporting the performance of urine dipstick tests (leukocyte esterase [LE] and/or nitrite), Gram stain, or microscopic analysis of spun or unspun urine...

Eighty eight severely malnourished preschool children (Grade III or Grade IV, IAP classification) were studied to find out the prevalence of urinary tract infection (UTI). Fifty three well nourished preschool children served as controls. Urine samples were collected by suprapubic aspiration in children below 3 years and in older children a clean catch midstream sample of urine was collected. Th...

OBJECTIVES Traditionally, urine cytology has been considered as the gold standard for bladder cancer screening. However, new methods are playing new roles in these cases. In order to assess the value of cytology of voided urine we performed one comparative study between cytology and biopsy. METHODS We retrospectively analyzed the results of urine cytology and biopsy follow-up in 109 patients....

statement of problem: primary teeth discoloration can cause mentally and socially unpleasant effects in children. this can also be a sign of systemic disease. despite the importance of this subject, a comprehensive study has not been performed yet. purpose: the aim of this study was determining the frequency of different types of primary teeth discoloration. materials and methods: in this cross...

Urinary biomarkers of kidney injury are an area of ongoing research in nephrology. For years, urinary eosinophils have been used as biomarkers for acute interstitialnephritis (AIN).Thecharacteristics thatwould make eosinophiluria a useful biomarker for AIN include that (1) eosinophils are consistently present in the urine of patients with AIN (i.e., AIN is characterized by an eosinophilic inter...

PURPOSE To diagnose the urothelial carcinoma of the bladder by measuring CA19-9 level in the urine. MATERIALS AND METHODS This study was conducted on 47 patients with histopathologically confirmed urothelial cancer and 50 control subjects. The urinary level of CA19-9 was measured in both groups by enzyme-linked immunosorbent assay after concentration of urine with Bio-Gel dry beads. Urine cyt...
