objective: cone beam computed tomography (cbct) is applied for the imaging of the maxillofacial and dental structures, particularly for surgical treatments and dental implants. the aim of this study was to assess the effect of slice thickness on the accuracy of cbct linear measurements. methods: in this diagnostic accuracy study, forty-two titanium pins with the same dimensions were inserted in...

In this paper, we evaluate the viability of using a 3D parametric surface model of the fetal cranium to extract diagnostic 2D ultrasound (US) image planes and biometric measurements useful in fetal growth monitoring. The parametric surface deforms to tightly delineate the inner cranial boundary, and its topology-preserving property defines a coordinate space which allows for consistent sampling...

The contribution of cognitive bias toward diagnostic error has been well documented.1–7 Previous research exploring the effects of these cognitive pitfalls centers on examples from internal and emergency medicine, but it is fair to presume that pediatric hospitalists remain equally vulnerable to such cognitive error.8 To improve the overall awareness of cognitive bias within inpatient pediatric...

pasteurella multocida (p. multocida) is an important pathogen of various domestic animals. the outer membrane proteins (omps) play a major role in pathogenesis and immunogenicity of p. multocida. the aim of the study was to develop indirect enzyme linked immuno sorbant assay (elisa) based on omps to ascertain the antibody titers in animals post-infection or to gauge the potency of vaccine. the ...

The sensitivity, specificity and likelihood ratios of binary diagnostic tests are often thought of as being independent of disease prevalence. Empirical studies, however, have frequently revealed substantial variation of these measures for the same diagnostic test in different populations. One reason for this discrepancy is related to the fact that only few diagnostic tests are inherently dicho...

Guidelines exist for the assessment of attention deficit/hyperactivity disorder (ADHD), but they are often unclear as to how a clinician should consider multiple informants, methods, and co-occurring symptoms to reach an overall diagnostic probability for an individual patient. The current study used receiver operating characteristic analyses and evidence-based medicine methods to evaluate the ...
