Regurgitant flow in apparently normal valve prostheses: improved detection and semiquantitative analysis by transesophageal two-dimensional color-cod…
1990
In 128 patients with apparently normally functioning prosthetic valves ( n = 136) in the aortic position ( n = 79) and the mitral position ( n = 57), the prevalence of transprosthetic regurgitant flow was studied by use of transthoracic and transesophageal two-dimensional color-coded Doppler echocardiography. With the transthoracic approach, regurgitant flow was detected in early systole or diastole for 28% of the mitral prostheses and for 29% of the aortic prostheses. With transesophageal color-coded Doppler echocardiography, regurgitant jets were visualized for 95% of the mitral prostheses and for 44% of the aortic prostheses. In 40% of the Bjork-Shiley prostheses and 88% of the St. Jude …
B-Lines for the assessment of extravascular lung water: Just focused or semi-quantitative?
2020
BACKGROUND B-lines as typical artefacts of lung ultrasound are considered as surrogate measurement for extravascular lung water. However, B-lines develop in the sub-pleural space and do not allow assessment of the whole lung. Here, we present data from the first observational multi-centre study focusing on the correlation between a B-lines score and extravascular lung water in critically ill patients suffering from a variety of diseases. PATIENTS AND METHODS In 184 adult patients, 443 measurements were obtained. B-lines were counted and expressed in a score which was compared to extravascular lung water, measured by single-indicator transpulmonary thermodilution. Appropriate correlation coe…
Clinically atypical spitzoid lesions: semi-quantitative histologic index correlation with dermoscopic scores (ABCD rule, 7-point checklist and patter…
2014
Background The distinction of Spitz and Reed nevi with atypical features from melanoma may be a difficult task. In these cases, the dermoscopic scores could bring variable results and not always correlate with the histologic diagnosis. Objective The aim of this study was to compare the histopathologic and dermoscopic findings in a cohort of clinically atypical Spitz and Reed nevi. Methods We retrospectively reviewed 19 cases of atypical Spitz and Reed nevi from our files. We constructed a new semi-quantitative histologic index (HI) based on the reproducible microscopic features, and correlated it with two dermoscopic scores: ABCD and 7-point checklist, as well as with the predominant dermos…
