Congenital left ventricular out-pouching, consisting of left ventricular aneurysms, left ventricle diverticulae, and double-chambered left ventricle, is a rare cardiac malformation. Criteria to differentiate between left ventricular aneurysm and diverticulum are defined. Reports of left ventricular accessory chamber in the medical literature are rare. In this article, we present a case of left ventricular accessory chamber diagnosed during the late prenatal period. Review of the literature, imaging modalities used for differentiation of the nature of this lesion, and management plan are discussed.
Here, we report the isolation, whole-genome sequencing, and annotation of four novel
Pseudomonas
isolates. We also evaluate the biosynthetic potential of each genome.
Purpose: This retrospective study compares point-of-care ocular ultrasound to MRI in order to establish preliminary data for and identify challenges to a multicenter study into the utility of ocular ultrasound for diagnosing optic neuritis. Methods: Our ultrasound archive was queried to identify subjects suspected of having optic neuritis who underwent ocular ultrasound and MRI of the brain or orbit. Blinded ultrasounds were reviewed by ultrasound faculty. The presence of optic disc elevation, optic nerve, or sheath dilation, and overall impression were recorded and compared to MRI results. Sensitivity and specificity of each ultrasound finding and the overall impression, as well as agreement between the raters, were calculated. Results: Sensitivity and specificity of ultrasound for MRI confirmed optic neuritis was 100 % (95 % CI 54.1-100) and 58.3 % (95 % CI 27.7-84.8). Optic nerve sheath diameter had nearly perfect agreement (κ = 0.8828), however agreement on optic disc elevation (κ = 0.5641), nerve diameter (κ = 0.2174), and overall agreement (κ = 0.1818) were moderate, fair, and poor, respectively. Conclusions: This preliminary study estimates test characteristics of ocular ultrasound for the diagnosis of optic neuritis for the purposes of power analysis and to identify potential pitfalls in preparation for a larger prospective investigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
