Objectives: To define diagnostic performance of magnetic resonance cholangiography (MRC) at the Clinic Center (Hospital de Clínicas) and to compare it with data reported in international bibliography. Methods: A retrospective study was undertaken; 126 MRC examinations were done to 126 patients within the period December 2010-July 2013. The results were correlated with endoscopic retrograde chol...

Two of the most promising new remote sensing technologies for increasing accuracy and efficiency of forest inventory are tree-wise or stand-wise measurements of airborne laser scanner data or 2(2D) and 3-dimensional measurements (3D) of digital aerial photographs. The aim of the study was to compare 3D measurements of digital aerial photographs and laser scanning to 2D measurements of digital a...

AIM to get a recommendation on the best frailty syndrome diagnostic tools, that will be able to be practiced on a daily setting in Indonesia. METHODS this is a cross-sectional study with diagnostic test approach, conducted to patients in the Geriatric Outpatient Clinic of Cipto Mangunkusumo National Referral Hospital on May-June 2013. Each subject underwent a frailty evaluation using CHS, SOF...

OBJECTIVE To asses the value of second-look ultrasound (US) for identifying BIRADS 3 (Breast Imaging Reporting Data System) mammary lesions detected by breast Magnetic Resonance imaging (MRI). MATERIALS AND METHODS From April 2008 to May 2009 330 breast MRI were performed of which 60 patients are classified as BIRADS 3. 84 lesions underwent second-look US and percutaneous vacuum biopsy Vacora...

UTI is the most common hospital acquired infections, accounting for 35% in hospitalized patients. Early diagnosis and prompt treatment of UTI in CKD patients is necessary to prevent grievous complications. The objective of this study is to determine diagnostic accuracy of multi dipstick tests for detecting UTI in CKD population and study spectrum of UTI in CKD. CKD patients attending Nephrology...

Validation of a PCR test to detect hilA gene sequences of Salmonella spp. was performed in blood and faeces samples from typhoid fever and salmonellosis patients. Sensitivity (S), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of the PCR in blood samples were performed by testing: 37 patients with clinical diagnosis of typhoid fever, 34 of them confirmed b...

INTRODUCTION This study combined data across four independent cohorts to examine the positive and negative predictive values of an Alzheimer's disease (AD) blood test if implemented in primary care. METHODS Blood samples from 1329 subjects from multiple independent, multiethnic, community-based, and clinic-based cohorts were analyzed. A "locked-down" referent group of 1128 samples was generat...

The objective of this study is to assess the value of postcone endocervical curettage, after conization of cervical intraepithelial neoplasia or carcinoma as a predictive tool for residual lesions. This is a retrospective observational study. All data were obtained by the University Hospital of Zurich, Department of Gynaecology. One hundred fifty patients underwent hysterectomy within 12 months...

Many patients with Chagas disease live in remote communities that lack both equipment and trained personnel to perform a diagnosis by conventional serology (CS). Thus, reliable tests suitable for use under difficult conditions are required. In this study, we evaluated the ability of personnel with and without laboratory skills to perform immunochromatographic (IC) tests to detect Chagas disease...

AIM The aim of our study was to evaluate the sensitivity and specificity of Nocturnal Oximetry (NO) as a diagnostic screening tool for obstructive sleep apnoea hypopnoea syndrome (OSAHS), compared with polysomnography (PSG) as the gold standard. METHODOLOGY 63 patients with clinical suspicion of OSAHS and exclusion of respiratory disease underwent PSG and NO. We then determined NO sensitivity...
