OBJECTIVE: To review the literature about the positive predictive value of Breast Imaging Reporting and Data System (BI-RADS®) categories 3, 4 and 5. MATERIALS AND METHODS: A research was performed in the online Medline database, entering the terms “predictive value” and “BI-RADS”. Eleven studies were included in this review. RESULTS: The positive predictive values ranged respectively between 0...

This study was performed to assess the efficiency of polymerase chain reaction (PCR) directly from sputum for the diagnosis of pulmonary tuberculosis by comparison between HIV-positive and HIV-negative individuals. Sputum samples were collected from hospitalized patients admitted with a clinical diagnosis of pulmonary tuberculosis, and subjected to smear microscopy, culture on LJ medium and det...

In this article, a new combined approach of a decision tree and clustering is presented to predict the transmission of genetic diseases. In this article, the performance of these algorithms is compared for more accurate prediction of disease transmission under the same condition and based on a series of measures like the positive predictive value, negative predictive value, accuracy, sensitivit...

INTRODUCTION The Identification of Seniors At Risk-Hospitalised Patients (ISAR-HP) has recently been included in guidelines as a frailty indicator to identify patients for comprehensive geriatric assessment. Previous studies showed that the conventional cut-off score incorrectly classifies a high percentage of patients as high risk. We aimed to optimise the predictive value of ISAR-HP by using ...

BACKGROUND Fever is a well-known side effect of misoprostol, but clinically difficult to distinguish from an intra uterine infection. The aim of this study was to determine the incidence of fever in terminations of pregnancy (TOP) using misoprostol and to evaluate fever as indication of intra uterine infection. METHODS A retrospective cohort study was performed. Consecutive second trimester T...

BACKGROUND Early biomarkers are helpful for predicting clinical endpoints and for evaluating efficacy in clinical trials even if the biomarker cannot replace clinical outcome as a surrogate. The building and evaluation of an association model between biomarkers and clinical outcomes are two equally important concerns regarding the prediction of clinical outcome. This paper is to address both is...

OBJECTIVE To validate a revised version of the paediatric South African Triage Scale (SATS) against admission as a reference standard and compare the sensitivity of triage using: (i) clinical discriminators; (ii) an age-appropriate physiological composite score; and (iii) a combination of both. METHODS A prospective cohort study was undertaken validating the revised paediatric SATS against ou...

The antigen capture ParaSight-F test was evaluated during a drug sensitivity survey in a hypoendemic region of northern Vietnam. When only asexual blood forms of P. falciparum were considered, sensitivity of ParaSight-F was 100%, specificity 88% (95% CI 95-80%), positive predictive value 68% (95% CI 85-50%) and negative predictive value 100%. ParaSight-F proved very convenient for rapid screeni...

Early detection of extravasation is important, but conventional methods of detection lack objectivity and reliability. This study evaluated the predictive validity of thermography for identifying extravasation during intravenous antineoplastic therapy. Of 257 patients who received chemotherapy through peripheral veins, extravasation was identified in 26. Thermography was performed every 15 to 3...
