In a continuous process such as caries, it is important to possess criteria or instruments that allow the lesions to be diagnosed at early stages so that preventive or interceptive treatments can be applied before cavitation takes place. The present study seeks to assess the diagnostic efficacy of the International Caries Detection and Assessment System (ICDAS II) criteria and the DIAGNOdent laser fluorescence (LF) pen in occlusal caries lesions, using histological sections as the gold standard. Sixty-four permanent teeth were examined by two researchers who previously performed and calibrated both the ICDAS II criteria and the use of DIAGNOdent pen...

INTRODUCTION: There is still no general consensus about the management of osteoporotic vertebral fractures. Recommendations depend on type of fracture, grade of instability, bone quality, and general conditions of the patient. Spontaneous fractures may be considered to be treated different compared to cases with high-velocity trauma. METHODS: According to the DVO, patients without trauma should first be treated conservatively. However, there is no more strict time protocol of 3 or 6 week conservative treatment before operations may be indicated...

Candida spp. are the most common causes of fungemia. Rapid and accurate diagnostic methods are very important for appropriate management of candidemia. At present, blood culture is the essential diagnostic test despite it has a long detection time and low sensitivity rate. We aimed to investigate the ways to shorten the turnaround time from blood culture collection to final identification in candidemia. Sixty clinical bloodstream isolates of Candida were included and the Plus Aerobic/F, Peds Plus/F and Mycosis IC/F (MICF) bottles were used with BACTEC 9240 blood culture instrument...

STUDY OBJECTIVES: Restless legs syndrome, also known as Willis-Ekbom disease (RLS/WED), is a frequent condition, though its pathophysiology is not completely understood. The diagnosis of RLS/WED relies on clinical criteria, and the only instrumental tool, the suggested immobilization test, may lead to equivocal results. Recently, neurophysiological parameters related to F-wave duration have been proposed as a diagnostic aid. The aim of this study is to assess and compare the diagnostic values of these parameters in diagnosis of RLS/WED...

Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...

Current water quality monitoring methods rely on growth-based measurements to detect fecal indicator bacteria, such as Escherichia coli and enterococci, and Staphylococcus aureus (S. aureus). These growth-based measurements, however, can take days to complete. This is a significant limitation in the evaluation of contaminated food and water sources. Various methods for selective in vitro detection of S. aureus have also been reported; however, these strategies, such as ELISA, agar-diffusion, PCR, or liquid chromatography-tandem mass spectrometry, all require overnight culturing or sophisticated instrumentation...

Imaging devices such as the Heidelberg Retinal Tomograph (HRT3), scanning laser polarimetry (GDx), and optical coherence tomography (OCT), play an important role in glaucoma diagnosis. A systematic search for evidence-based data was performed for prospective studies evaluating the diagnostic accuracy of HRT3, GDx and OCT. The diagnostic odds ratio (DOR) was calculated. To compare the accuracy among instruments and parameters, a meta-analysis considering the hierarchical summary receiver operating characteristic (H-SROC) model was performed...

The key coagulation factor FVII, and its activated form FVIIa, present a major interest for their role at the initiation phase of blood coagulation, and because they can activate all blood coagulation cascade, through the extrinsic, but also the intrinsic pathway. Blood activation initiated through FVII is first presented, as it is understood nowadays. Measurement of FVII and FVIIa were of main interest for epidemiological studies, but FVIIa contribution to assay results was only deduced. The introduction of specific FVIIa assays, functional or immunoassays, allowed measuring directly FVIIa without any interference of non-activated FVII, or other coagulation factors or their activated forms...

Since it was first introduced, the main goal of PET/CT has been to provide both PET and CT images with high clinical quality and to present them to radiologists and specialists in nuclear medicine as a fused, perfectly aligned image. The use of fused PET and CT images quickly became routine in clinical practice, showing the great potential of these hybrid scanners. Thanks to this success, manufacturers have gone beyond considering CT as a mere attenuation corrector for PET, concentrating instead on design high performance PET and CT scanners with more interesting features...

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the accurate diagnostic method for pancreatic masses and its accuracy is affected by various FNA methods and EUS equipment. Therefore, we aimed to elucidate the instrumental and methodologic factors for determining the diagnostic yield of EUS-FNA for pancreatic solid masses without an on-site cytopathology evaluation.We retrospectively reviewed the medical records of 260 patients (265 pancreatic solid masses) who underwent EUS-FNA. We compared historical conventional EUS groups with high-resolution imaging devices and finally analyzed various factors affecting EUS-FNA accuracy...

Argument The sphygmograph as designed and tested by Jules-Étienne Marey - an apparatus destined to write pulse tracings on paper - revolutionized medical diagnostics in the early 1860s. Since the accuracy with which this device registered and objectified the pulse was controversial from the outset, the young scholar Ernst Mach (soon to become a leading theoretician and philosopher) decided to thoroughly examine Marey's sphygmograph. The investigation led to the invention of an alternative, truly Machian, sphygmograph...

Introduction: Only the Mini mental state examination (MMSE) and Montreal Cognitive Assessment scale have been validated in a Sri Lankan population for the assessment of cognitive functions. Both tests are deficient in the number of domains assessed. Therefore validation of Repeatable Battery for Assessment of Neuropsychological Status is important as it assesses most of the cognitive domains. Objectives: To culturally adapt RBANS and investigate the validity and reliability of culturally adapted RBANS (RBANS-S)...

BACKGROUND: Cerebellar mutism syndrome (CMS) or posterior fossa syndrome (PFS) consists of a constellation of neuropsychiatric, neuropsychological and neurogenic speech and language deficits. It is most commonly observed in children after posterior fossa tumor surgery. The most prominent feature of CMS is mutism, which generally starts after a few days after the operation, has a limited duration and is typically followed by motor speech deficits. However, the core speech disorder subserving CMS is still unclear...

Chronic thromboembolic pulmonary hypertension (CTEPH) is the most severe long term complication of acute pulmonary embolism (PE). Untreated, CTEPH is associated with a very poor prognosis and high risk of mortality, although curation can be achieved by surgical removal of the obstructive endothelialised thromboemboli from the pulmonary arteries. Early CTEPH diagnosis may improve surgical possibilities and patients outcome. Currently, early diagnosis of CTEPH is a major challenge as demonstrated by an unacceptable median diagnostic delay of over a year and as a result, surgery is impossible in 40% of patients...

To date global research on depression has used assessment tools based on research and clinical experience drawn from Western populations (i.e., in North American, European and Australian). There may be features of depression in non-Western populations which are not captured in current diagnostic criteria or measurement tools, as well as criteria for depression that are not relevant in other regions. We investigated this possibility through a systematic review of qualitative studies of depression worldwide. Nine online databases were searched for records that used qualitative methods to study depression...

Rare earth elements (REE) consist of lanthanides (from La to Lu), together with yttrium and scandium, in which anthropogenic REE, such as gadolinium (Gd), lanthanum (La), and samarium (Sm), has emerged as micro-contaminants in natural waters in highly developed countries. Here, we collected water samples in the Han River (HR) and its tributaries flowing through Seoul Capital Area, the world's second largest metropolitan area in order to examine how and to what extent anthropogenic REE anomalies may occur. Water samples show higher light REE concentrations than heavy REE concentrations, while wastewater treatment plant (WWTP) samples display much higher heavy REE concentrations due to high Gd concentration...

Recent literature has touted the use of canine olfaction as a diagnostic tool for identifying pre-clinical disease status, especially cancer and infection from biological media samples. Studies have shown a wide range of outcomes, ranging from almost perfect discrimination, all the way to essentially random results. This disparity is not likely to be a detection issue; dogs have been shown to have extremely sensitive noses as proven by their use for tracking, bomb detection and search and rescue. However, in contrast to analytical instruments, dogs are subject to boredom, fatigue, hunger and external distractions...
