We report a case of congenital lumbosacral limb duplication at the pelvis, lower limb, and foot of a 4-year-old boy. The patient presented with a supernumerary lower limb joined at the lumbosacral region by a bony connection. A pseudo-navel and a pseudo-penis were found on the supernumerary limb and foot duplication was noted at the end. Radiography and a 3-dimensional computed-tomography recon...

Segmentation, Unsupervised clustering, Mean shift, Cardiac images, Human heart, Left ventricle. In this paper an image segmentation scheme that is based on combinations of a nonparametric technique and a seed based clustering algorithm is reported. The method has been applied to clinical unsubtracted angiograms of the human heart. The first step of the method consists in applying a mean shiftba...

The notion of left convergent sequences of graphs introduced by Lovász et al. (in relation with homomorphism densities for fixed patterns and Szemerédi’s regularity lemma) got increasingly studied over the past 10 years. Recently, Nešetřil and Ossona de Mendez introduced a general framework for convergence of sequences of structures. In particular, the authors introduced the notion of QF -conve...

M itral regurgitation (MR) is a common form of valvular disease1 and its severity is associated with excess morbidity and mortality from left ventricular (LV) remodeling, left atrial remodeling, pulmonary pressure elevation, and progression to left and right heart failure.2-6 Current American Society of Echocardiography (ASE) Guidelines7 propose vena contracta (VC) width as a simple semi-quanti...

This study uses elliptic Fourier analysis (EFA), an outline method of shape analysis, for describing hoof contours symmetries in the Catalan Pyrenean Horse (“Cavall Pirinenc Català”, CPC), a breed from the Spanish Pyrenees. Hoof outlines of 54 limbs (26 forelimbs and 28 hindlimbs, including the same number of left and right limbs) obtained from 15 CPC horses were compared using EFA. Symmetry wa...

BACKGROUND We reported a case of sudden monocular vision loss after calcium hydroxyapatite (CaHA) injection into the nasal tip and dorsum with detailed retina images. CASE PRESENTATION A healthy, 35-year-old woman received CaHA filler injection for nose augmentation. Ten minutes after the procedure, she developed nausea, vomiting, headache, ptosis, and left periorbital pain. After 30 minutes,...
