AIM To assess liver fibrosis (LF) in hepatitis C virus (HCV) and alcoholic liver disease (ALD), estimate health outcomes and costs of new noninvasive testing strategies. METHODS A Markov model was developed to simulate LF progression in HCV and ALD for a cohort of 40-year-old men with abnormal levels of transaminases. Three different testing alternatives were studied: a single liver biopsy; a...

Disinfected and non-disinfected samples have been used to determine the accuracy of the ISO procedure (ISO 9308-1) for detection of E. coli in drinking water. Samples were analysed using the ISO procedure at both 36 and 44 degrees C and using the defined substrate technology method Colilert-18/Quanti-Tray (Colilert-18). Utilizing the confirmation procedure described in ISO 9308-1, large numbers...

INTRODUCTION Lupus anticoagulant (LAC) testing is challenging. Most data are derived from a well-controlled study environment with potential alterations to daily routines. The aim of this retrospective cohort study was to assess the capacity of various LAC screening tests and derived mixing tests to predict a positive result in subsequent confirmation tests in a large cohort of patients. MATE...

In general, the dengue ́s laboratory diagnosis aims: 1) laboratory, serologic and/or virologic infection ́s confirmation; 2) identification of circulating serotypes; 3) laboratory confirmation of severe and fatal cases; 4) support for epidemiological investigations to determine the levels of disease transmission and 5) performance of molecular studies in order to identify existing genotypes in th...

BACKGROUND AND AIMS Confirmation of correct endotracheal tube placement is essential immediately after intubation for general anaesthesia.
