Background: We determined the diagnostic accuracy of the Edinburgh Claudication Questionnaire (ECQ) in 1 generation Black African-Caribbean UK migrants as previous diagnostic questionnaires have been found to be less accurate in this population. We also determined the diagnostic accuracy of translated versions of the ECQ in 1 generation South Asian UK migrants, as this has not been investigated...

AIM To identify the clinical predictors and assist surgeons in their clinical management of obstructive sleep apnoea (OSA) - a prospective study with a new approach to analyse the static and dynamic upper airway morphology between patients with OSA and normal subjects. To introduce a new method of assessment for surgical outcome. MATERIALS AND METHODS Quantitative computer-assisted videoendos...

We examined the quantitative electrocardiographic differentiation of acute pericarditis from normal variant ST-T changes. The ECGs of 19 patients with acute pericarditis were compared with those of 20 subjects with typical normal variant changes. Patients were excluded if their ECGs demonstrated conditions that markedly altered repolarization. The positive predictive values (PPV) and negative p...

BACKGROUND AND PURPOSE Previous studies quantifying moderate and severe carotid stenosis by direct millimeter measures on CT angiography (CTA) did not consider how prevalence and gender may influence classification cutoff values. MATERIALS AND METHODS Three hundred nineteen carotid arteries were evaluated in consecutive patients with known or suspected carotid artery disease. Millimeter measu...

OBJECTIVE To compare diffusion tensor tractography (DTT) and motor evoked potentials (MEPs) for estimation of clinical status in patients in the subacute stage of stroke. METHODS Patients with hemiplegia due to stroke who were evaluated using both DTT and MEPs between May 2012 and April 2015 were recruited. Clinical assessments investigated upper extremity motor and functional status. Motor s...

We investigated the utility of noncontrast enhanced endosonography (EUS) in predicting the severity of acute pancreatitis (AP) during the first 72 to 96 h of admission.In total, 187 patients with acute biliary pancreatitis were included. The patients were classified into 2 groups as having severe and mild AP according to the Modified Glasgow scoring and computerized tomography severity index (S...

Both multi-parametric MRI (mpMRI) and the Prostate Health Index (PHI) have shown promise in predicting a positive biopsy in men with suspected prostate cancer. Here we investigated the value of combining both tests in men requiring a repeat biopsy. PHI scores were measured in men undergoing re-biopsy with an mpMRI image-guided transperineal approach (n = 279, 94 with negative mpMRIs). The PHI w...

OBJECTIVES To evaluate the agreement and the association with FEV(1), FEV(6) and FEV(1)/FEV(6) measured with the Vitalograph-COPD-6 portable device and the FEV(1), FVC and FEV(1)/FVC by conventional spirometry, and to analyse the validity of this device to detect obstruction. METHODOLOGY A cross-sectional, descriptive, prospective study, that included 180 subjects. A conventional spirometry a...

BACKGROUND Malignant peripheral nerve sheath tumors (MPNSTs) are a serious complications of neurofibromatosis type 1 associated with poor prognosis and deeper lesions can be difficult to diagnose. 18-FDG PET improves the detection of malignancies. However, the criteria for malignancy, notably the SUVmax threshold, are not standardized. Therefore, the aim of the study was to evaluate a semi-quan...

OBJECTIVE This study sought to assess the real incidence of pN2 among patients with non-small-cell lung cancer (NSCLC) (cN0) with negative mediastinal uptake of 2-deoxy-2-(18F)-fluoro-o-glucose (FDG). METHODS During 30 consecutive months (January 2007-May 2009), all patients with NSCLC scheduled for surgery in our unit had a preoperative FDG-positron emission tomography (PET)/computed tomogra...
