OBJECTIVE To determine the value of positron emission tomography (PET) with contrast-enhanced computed tomography (CT) in assessing the need for neck dissection by retrospectively reviewing the pathology reports of patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (SCC). DESIGN Retrospective cohort study. SETTING Tertiary medical center. PATIENTS Se...

Bloodstream infections (BSIs) are a significant cause of morbidity and mortality. Successful patient outcomes are diminished by a failure to rapidly diagnose these infections and initiate appropriate therapy. A rapid and reliable diagnostic platform of high sensitivity is needed for the management of patients with BSIs. The combination of an RNA-dependent nucleic acid sequence-based amplificati...

BACKGROUND The aim of the study was to determine the efficacy of Fibroscan versus noninvasive markers, i.e. nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS); Aspartate-aminotransferase (AST)/platelet ratio (APRI); and AST/Alanine-aminotransferase (AAR) as a screening tool in NAFLD patients with high risk of liver fibrosis. METHODS This is a single-center study carried out in pati...

Purpose Parallel imaging allows for a considerable shortening of examination times. Limited data is available about the diagnostic accuracy of an accelerated knee MRI protocol based on parallel imaging evaluating all knee joint compartments in a large patient population compared to arthroscopy. Materials and Methods 162 consecutive patients with a knee MRI (1.5 T, Siemens Aera) and arthroscopy ...

BACKGROUND Combined testing of high-sensitivity cardiac troponin T (hs-cTnT) and copeptin at presentation provides a very high-although still imperfect-negative predictive value (NPV) for the early rule-out of acute myocardial infarction (AMI). We hypothesized that a second copeptin measurement at 1 h might further increase the NPV. METHODS In a prospective diagnostic multicenter study, we me...

INTRODUCTION If package counts on abdominal CTs of body-packers were known to be accurate, follow-up CTs could be avoided. The objective was to determine the accuracy of CT for the number of concealed packages in body-packers, and the reliability of package counts reported by body-packers who admit to concealing drugs. METHODS Suspected body-packers were identified from the emergency departme...

BACKGROUND Guidance from the National Institute for Health and Clinical Excellence recommends one or two questions as a possible screening method for depression. Ultra-short (one-, two-, three- or four-item) tests have appeal due to their simple administration but their accuracy has not been established. AIM To determine whether ultra-short screening instruments accurately detect depression i...

The applicability of Net Present Value (NPV) in an investment project is becoming more and more popular in the field of engineering economics. The classical NPV methodology involves only the precise and accurate data of the investment project. In the present communication, we give a new mathematical model for NPV which uses the concept of intuitionistic fuzzy set theory. The proposed model is b...

The INFLU A.B-Quick and Directigen Flu A+B enzyme immunoassays were compared with direct immunofluorescence and cell culture for detection of influenza A and B viruses in a total of 255 patient specimens. Both assays identified 23 of 42 influenza A viruses (sensitivity, 54.8%; specificity, 100%; positive predictive value [PPV], 100%; negative predictive value [NPV], 91.8%). The INFLU A.B-Quick ...
