Abstract Background One of the most readily available and cost effective tests in the diagnosis of urinary tract infections (UTI) is the urinalysis.

Abstract:

<strong>Background</strong>: Dipstick urinalysis, which is a simple but very important diagnostic procedure in paediatric nephro-urology, provides information about multiple physicochemical properties of urine. It detects common urinary abnormalities in children which could result from a wide range of conditions. Proteinuria, haematuria and glycosuria for example may be pointers to serious underlying pathologies in the newborn. This study was undertaken to determine baseline findings on dipstick urinalysis in healthy neonate in Port Harcourt as there is paucity of such a study in our environme

Abstract Background: Urine test strip results are generally reported in categories (i.e., ordinal scaled), but automated strip readers are now available that can report quantitative data. We investigated the possible use of these meters to complement flow cytometry of urine and compared reflectance readings with quantitative determinations of urinary glucose and microalbumin. Methods: We compared URISYS 2400 (Roche) quantitative reflectance data with data from the UF-100 (Sysmex) and biochemical data for 436 nonpathologic and pathologic urine samples.

Abstract:

Background: Urinary tract infections (UTI) are among the most common infections in children. The primary tool to detect UTI is dipstick urinalysis; however, this has limited sensitivity and specificity. Therefore, urine culture has to be performed to confirm a UTI. Urinary volatile organic compounds (VOC) may serve as potential biomarker for diagnosing UTI. Previous studies on urinary VOCs focused on detection of UTI in a general population; therefore, this proof-of-principle study was set up in a clinical high-risk pediatric population.

It is caused by Schistosoma haematobium and causes considerable public health problems to schoolchildren. Ethiopia, after mapping the distribution of the disease (2013 to 2015), launched school-based mass deworming program to treat schoolchildren for schistosomiasis and soil-transmitted helminthiasis (STH) across the country since 2015. However, there is no recent information about the prevalence of the disease among schoolchildren in the current study areas. Diagnostic performance of urine
