this study was aimed to evaluate the efficacy of dipstick tests (leukocyte esterase and nitrite) in diagnosis of spontaneous bacterial peritonitis (sbp) in cirrhotic patients. forty six children with ascites hospitalized between 2009 and 2010 in children medical center were enrolled in this study. reagent strip assays for leukocyte esterase and nitrite were performed on ascetic fluid and the re...

BACKGROUND The presence of leukocyte esterase in the synovial fluid has recently been proposed as a marker for periprosthetic joint infection. However, the sensitivity and specificity of leukocyte esterase has not been determined when matched for the current, most inclusive Musculoskeletal Infection Society (MSIS) criteria for periprosthetic joint infection. METHODS The presence of leukocyte ...

Microscopy and leukocyte esterase activity, both employed as screening techniques for urine cultures, were evaluated with respect to two distinct populations, male and female. When 424 urine specimens from males were examined, 95% of the Gram-stained smears and 91% of the leukocyte esterase tests correctly correlated with culture results, indicating significant bacteriuria. There were no signif...

Urinalysis and culture are the two most common investigations performed in a microbiology laboratory. Commercial Dipsticks which detect proteins and various enzymes may offer a rapid and inexpensive alternative to urinalysis and culture. An evaluation of the utility of urinary dipsticks (Multistix 10 SG) in predicting urinary tract infections (UTI) was undertaken. A total of 667 urine samples w...

conclusions the use of leukocyte esterase urine dipstick test can be a quick and easy method in early diagnosis of sbp to start the treatment until preparation of sbp-cell count results. results in this study, 100 patients with ascites due to cirrhosis, with an average age of 38.9 ± 6.54 years were evaluated. twenty cases had positive results, of whom 17 cases were also detected based on the st...

Background: Gold standard for the diagnosis of urinary tract infections (UTIs) is urine culture, but it takes longer bacterial growth on culture media. Leukocyte esterase a simple strip testing sample, so less time in diagnosing cases UTI. Objective: To determine diagnostic accuracy leukocyte detection infection children taking as gold standard. Materials and Methods: This cross-sectional study...

This study was aimed to evaluate the efficacy of dipstick tests (leukocyte esterase and nitrite) in diagnosis of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. Forty six children with ascites hospitalized between 2009 and 2010 in Children Medical Center were enrolled in this study. Reagent strip assays for leukocyte esterase and nitrite were performed on ascetic fluid and the re...

The present study evaluated the usefulness of the 1-min leukocyte esterase-nitrite tests in a tertiary-care hospital as a screening procedure to detect significant bacteriuria and correlated the findings with culture results. A total of 531 urine samples were reviewed, of which 484 were evaluated. Of the evaluated samples, 113 positive cultures (23.4%) were found, of which 93 (82.3%) were detec...

Background: Urinary tract infection is a common disease in childhood. The aim of this study was to determine the diagnostic performance of urinary analysis, assess the role of urine culture in determining its necessity and evaluate etiologic agents and antimicrobial resistance patterns in children with urinary tract infection.Methods: Our study was made by evaluating the patients who applied to...

It was shown in the preceding paper that incubation of the rabbit polymorphonuclearleukocyteswith phosphonate esters leads to an irreversible inhibition of the ability of the leukocyte to respond to the chemotactic factor. This "cell-dependent inhibition" was attributed to the inactivation by the phosphonates of an esterase existing in or on the leukocyte in an already activated state. As shown...
