Portal vein hypoplasia in dogs

Portal vein hypoplasia (PVH) is a congenital disorder, in which microscopic intrahepatic shunts are present, causing blood to bypass the liver sinusoids. As the clinical presentation and the laboratory findings are similar to those in dogs with an extrahepatic portosystemic shunt (EHPSS), differentiation between both disorders is based on the confirmation of a macroscopic shunt by diagnostic imaging techniques. This review highlights the major aspects of PVH, including the differentiation from EHPSSs, and the challenges to diagnose both disorders in dogs with concurrent PVH and EHPSS

Neural Kernel Surface Reconstruction

We present a novel method for reconstructing a 3D implicit surface from a large-scale, sparse, and noisy point cloud. Our approach builds upon the recently introduced Neural Kernel Fields (NKF) representation. It enjoys similar generalization capabilities to NKF, while simultaneously addressing its main limitations: (a) We can scale to large scenes through compactly supported kernel functions, which enable the use of memory-efficient sparse linear solvers. (b) We are robust to noise, through a gradient fitting solve. (c) We minimize training requirements, enabling us to learn from any dataset of dense oriented points, and even mix training data consisting of objects and scenes at different scales. Our method is capable of reconstructing millions of points in a few seconds, and handling very large scenes in an out-of-core fashion. We achieve state-of-the-art results on reconstruction benchmarks consisting of single objects, indoor scenes, and outdoor scenes.Comment: CVPR 202

Behandeling van een chronische huidwonde bij een hond via negatieve druktherapie

A four-year-and-eight-month-old whippet was presented with a chronic skin wound situated at the medial aspect of the right elbow. Because of its chronic nature, the wound was initially carefully debrided and subsequently treated by means of negative pressure therapy. This fairly new technique offers a wide range of advantages that improve the healing capacities of a chronic wound. The beneficial effect of negative pressure wound therapy on the development of a nice granulation bed was clear. In order to optimize the final result, an autologous skin grafting (full-thickness free mesh graft) was performed. By applying negative pressure on the skin graft, a quick and solid attachment of the graft was achieved. After a period of four weeks, the wound was almost completely healed despite various earlier attempts to successfully treat that wound in the two-months period prior to referral
