Deep Learning Predicts Molecular Subtype of Muscle-invasive Bladder Cancer from Conventional Histopathological Slides.

2020

Abstract Background Muscle-invasive bladder cancer (MIBC) is the second most common genitourinary malignancy, and is associated with high morbidity and mortality. Recently, molecular subtypes of MIBC have been identified, which have important clinical implications. Objective In the current study, we tried to predict the molecular subtype of MIBC samples from conventional histomorphology alone using deep learning. Design, setting, and participants Two cohorts of patients with MIBC were used: (1) The Cancer Genome Atlas Urothelial Bladder Carcinoma dataset including 407 patients and (2) our own cohort including 16 patients with treatment-naive, primary resected MIBC. This resulted in a total …

Laparoscopic minor pancreatic resections (enucleations/atypical resections). A long-term appraisal of a supposed mini-invasive approach

2012

A b s t r a c t Introduction: A few retrospective, small, often multicentric studies show encouraging results of laparoscopic minor pancreatic surgery, but do not allow for an evaluation of feasibility and effectiveness. Aim: Evaluation of the results of laparoscopic minor pancreatic resections (LMPR), including atypical resections and enucleations. Material and methods: The outcome of all consecutive patients undergoing LMPR in a tertiary care university hospi- tal specializing in the laparoscopic approach to solid organs (I.M.M., Paris - France) was retrospectively evaluated by the analysis of operating time, blood loss, conversion, morbidity, stay and late outcome. Results: Thirty-three …

ICUD-EAU International Consultation on Bladder Cancer 2012: Non–Muscle-Invasive Urothelial Carcinoma of the Bladder

2012

Item does not contain fulltext CONTEXT: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. OBJECTIVE: To critically review the recent data on the management of NMIBC to arrive at a general consensus. EVIDENCE ACQUISITION: A detailed Medline analysis was performed for original articles addressing the treatment of NMIBC with regard to diagnosis, surgery, intravesical chemotherapy, and follow-up. Proceedings from the last 5 yr of major conferences were also searched. EVIDENCE SYNTHESIS: The major findi…

Analysis of Candida auris candidemia cases in an Intensive Care Unit of a tertiary hospital

2021

Abstract Candida auris is a multi-resistant emerging fungus. Objectives To analyze the relationship between colonization by C. auris and the appearance of invasive candidiasis. Description of the sample of colonized patients, risk factors for colonization and/or infection, and calculation of mortality rates. Methodology Longitudinal observational study in an anesthesia intensive care unit in 2018. Results 2130 patients were admitted. Surveillance studies were positive in 124 patients; 118 cases involved skin colonization and 52 were pharyngeal. Patients with a positive blood culture were identified. A statistically significant association was found between pharyngeal colonization and the ap…

Minimally invasive mitral valve surgery: State-of-the-art and our experience

2015

The minimally invasive approach is becoming the standard-of-care for surgery of the mitral valve. As any less invasive strategy, it entails an increased surgical complexity. Standard-of-care mitral repair using the totally videoscopic approach is indeed reproducible; however, few specific data on patients with complex mitral valve disease are available in the published literature. The purpose of the present paper is to provide an overview of the current state-of-the-art in minimally invasive cardiac surgery, and a summary of recent evidence on the topic, with particular regard to the surgical techniques and comparisons with conventional surgery. The experience of the GVM Care and Research n…

Modeling the pelvic region for non-invasive pelvic intraoperative neuromonitoring

2016

Abstract Finite element analysis (FEA) of electric current distribution in the pelvis minor may help to assess the usability of non-invasive surface stimulation for continuous pelvic intraoperative neuromonitoring. FEA requires generation of quality volumetric tetrahedral mesh geometry. This study proposes the generation of a suitable mesh based on MRI data. The resulting volumetric mesh models the autonomous nerve structures at risk during total mesorectal excision. The model also contains the bone, cartilage, fat, skin, muscle tissues of the pelvic region, and a set of electrodes for surface stimulation. The model is ready for finite element analysis of the discrete Maxwell’s equations.

ONE-TROCAR VIDEO-ASSISTED STRIPPING TECHNIQUE FOR USE IN THE TREATMENT OF LARGE OVARIAN CYSTS IN INFANTS

2010

Abstract Background Management of ovarian cysts in infants is controversial; it can be conservative or surgical, and the management is determined by the cyst's size and sonographic features. Methods A surgical approach using a 10-mm umbilically placed operative laparoscope was taken in 3 female infants with antenatally diagnosed large, simple ovarian cysts. The contents of the cysts were partially aspirated and the cyst walls were stripped off the remaining ovarian parenchyma. No intraoperative or postoperative complications were recorded. Conclusions The one-trocar video-assisted stripping technique for large ovarian cysts in infants appears to be an ovarian-tissue-preserving procedure, an…

Real-Time Augmented Reality for Ear Surgery

2018

International audience; Transtympanic procedures aim at accessing the middle ear structures through a puncture in the tympanic membrane. They require visualization of middle ear structures behind the eardrum. Up to now, this is provided by an oto endoscope. This work focused on implementing a real-time augmented reality based system for robotic-assisted transtympanic surgery. A preoperative computed tomography scan is combined with the surgical video of the tympanic membrane in order to visualize the ossciles and labyrinthine windows which are concealed behind the opaque tympanic membrane. The study was conducted on 5 artificial and 4 cadaveric temporal bones. Initially, a homography framew…
