Fetal Endoscopic Tracheal Occlusion (FETO) for Left and Right Congenital Diaphragmatic Hernia in Canada

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To describe perinatal and short‐term pediatric outcomes and procedural safety of fetal endoscopic tracheal occlusion (FETO) in a Canadian national referral centre. Methods Retrospective study including all consecutive FETO cases at the Ontario Fetal Centre between 2010 and 2024.

Prenatal Diagnosis of Horseshoe Lung: A Report of Three Cases and Review of the Literature

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective Horseshoe lung is a rare congenital malformation in which the lungs are fused by a parenchymal isthmus. The current literature is very limited regarding cases of prenatal diagnosis and their outcome. Method We retrospectively examined three cases of fetuses with horseshoe lung diagnosed antenatally in our center from 2015 to 2024 ...

Decision-based AI Visual Navigation for Cardiac Ultrasounds [PDF]

open access: yesarXiv
Ultrasound imaging of the heart (echocardiography) is widely used to diagnose cardiac diseases. However, obtaining an echocardiogram requires an expert sonographer and a high-quality ultrasound imaging device, which are generally only available in hospitals.

A combinatorial proof of the Removal Lemma for Groups [PDF]

open access: yesarXiv, 2008
Green [Geometric and Functional Analysis 15 (2005), 340--376] established a version of the Szemer\'edi Regularity Lemma for abelian groups and derived the Removal Lemma for abelian groups as its corollary. We provide another proof of his Removal Lemma that allows us to extend its statement to all finite groups.

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

open access: yesPediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.

Equality in Laszlo Fejes Toth's triangle bound for hyperbolic surfaces [PDF]

open access: yesActa Sci. Math. (Szeged), 77 (2011), 669-679, 2012
For k>6, we determine the minimal area of a compact hyperbolic surface, and an oriented compact hyperbolic surface that can be tiled by embedded regular triangles of angle 2\pi/k. Based on this, all the cases of equality in Laszlo Fejes Toth's triangle bound for hyperbolic surfaces are described.

Functional Microendoscopy Reveals Calcium Responses of Single Cells in Tracheal Tuft Cells and Kidney Podocytes

open access: yesSmall, EarlyView.
A cost‐effective multicore‐fiber microendoscope for biological functional imaging is presented. The instrument is thin enough to image within the mouse trachea. It is applied to record responses of tracheal tuft cells to stimulation in vivo, as well as calcium and redox signals from various organs in situ.

Leiomioma benigno metastatizante de veia cava inferior: rara complicação tardia de histerectomia

open access: yesRevista do Colégio Brasileiro de Cirurgiões
Large vessel tumors diagnosis is usually difficult. Benign metastasizing leiomyoma is a rare condition occurring inside peripheral vessels. There are few publications about this tumor inside inferior vena cava.
