PURPOSE With growing interest in early imaging, the aim of our study was to define the most practical modality for routine clinical use for the diagnosis of acute pyelonephritis (APN). We compared the sensitivity of enhanced computerized tomography (CT), dimercaptosuccinic acid (DMSA) scintigraphy, and Doppler ultrasonography (DUS) by using clinical findings as the standard of reference. MATE...
This article reports an extension of powered inverse Rayleigh distribution via DUS transformation, named DUS-Powered Inverse (DUS-PIR) distribution. Some statistical properties suggested in particular, moments, mode, quantiles, order statistics, entropy, inequality measures and stress-strength parameter have been investigated extensively. To estimate the parameters, maximum likelihood estimatio...
OBJECTIVES Digital ulcers (DUs) occur in up to half of patients with systemic sclerosis (SSc) and may lead to infection, gangrene and amputation with functional disability and reduced quality of life. This study has elucidated the burden of SSc-associated DUs through identification of four patient categories based on the pattern of DU recurrence over a 2-year observation period. METHODS Patie...
OBJECTIVE To identify nailfold videocapillaroscopic features and other clinical risk factors for new digital ulcers (DUs) during a 6-month period in patients with systemic sclerosis (SSc). METHODS In this multicenter, prospective, observational cohort study, the videoCAPillaroscopy (CAP) study, we evaluated 623 patients with SSc from 59 centers (14 countries). Patients were stratified into 2 ...
INTRODUCTION Illicit drug users (DUs) are vulnerable to hepatitis C virus (HCV) infection. The shared use of illicit drugs is the main method of HCV transmission. METHODS A cross-sectional study was conducted in Breves, in northern Brazil. We surveyed 187 DUs to determine the prevalence of and factors associated with HCV infection. RESULTS The prevalence of anti-HCV antibodies was 36.9%, an...
The deontic logic dus is a deontic update semantics for prescriptive obligations based on the update semantics of Veltman. In dus the definition of logical validity of obligations is not based on static truth values but on dynamic action transitions. In this paper prescriptive prima facie obligations are formalized in update semantics. The logic formalizes the specificity principle, has reinsta...
Systemic sclerosis- (SSc-) related vasculopathy, as manifested by Raynaud's Phenomenon (RP) and digital ulcers (DUs), is associated with significant impairment of the quality of life and morbidity. The current vasoactive approach for SSc-RP, although employing vasodilators, is entirely off-label. PDE-5 inhibitors improve peripheral circulation, are well tolerated, and are widely used for variou...
This study aimed to evaluate the Chagas Disease Control Program which has operated since 1982 in the municipality of Berilo in the Jequitinhonha Valley, Minas Gerais, Brazil, based on evaluation of 5,242 domiciliary units (DUs) and 7,807 outbuildings over an eight-year period of epidemiological surveillance implanted in 1997. A total of 391 triatomines (280 Panstrongylus megistus and 111 Triato...
D e s c r i p t i o n o f t e s t s a n d d i a g n o s t i c s t a n d a r d DUS, MRA, and DSA were done within 4 weeks. The degree of stenosis on DUS was based on the peak systolic velocity (PSV) in the proximal internal carotid artery; analysis of DUS was based on a threshold of 70% stenosis, represented by a PSV of 270 cm/s. DSA was the diagnostic standard: A positive test result was define...
The aim of this study was to compare diagnostic efficiency of excretory urography (EU), ultrasonography-guided percutaneous antegrade pyelography (UGPAP), and renal Doppler ultrasonography (DUS) in New Zealand rabbits (n= 20) experimentally induced unilateral partial ureteral obstruction. The resistive index (RI) value was obtained from all rabbits prior to the induction. A partial ureteral obs...
