This is a retrospective quality assurance study of all frozen sections done at The Aga Khan University Hospital during a six year period (1986 to 1991). There were 1,031 frozen sections out of a cumulative total of 42,985 surgical specimens (2.39%). Nine hundred and severity-six (94.66%) were concordant. In 92 (8.9%) fresh specimens were brought from other hospitals of Karachi, in 37 cases (3.5...

abstract background: hypertension is the main risk factor of many diseases and the main reason of death all over the world. because the signs of hypertension are not clear, people do not feel its dangers and do not believe they are at risk. this problem makes preventing hypertension a great challenge for the health system. one factor that is related to lifestyle and is effective in preventing h...

We propose a novel framework to segment vessels on their cross-sections. It starts with a probabilistic vessel axis tracing in a gray-scale three-dimensional angiogram, followed by vessel boundary delineation on cross-sections derived from the extracted axis. It promotes a more intuitive delineation of vessel boundaries which are mostly round on the cross-sections. The prior probability density...

Background and Objective: Intraoperative consultation by frozen section is a high – risk procedure with important consequences. Therefore, it is critical to determine efficiency of frozen section performance periodically. This study was performed to determine the accuracy of frozen section in Urmia University of Medical Sciences. Materials & Methods:Inthis cross sectional study, we compared th...

Whole mount sections of the prostate are widely used in many laboratories. Macrocryosections of the gland; that is, whole mount frozen sections of the prostate from radical prostatectomies represent a useful new research protocol. The technique is very simple and does not require expensive equipment. (J Clin Pathol 2001;54:236–237)

Introduction In the pathology field, digital slide conferencing capabilities are obviously a highly necessary functionality when multiple participants need to simultaneously view the same digital slide from multiple, remote locations e.g. for frozen section teleconsultation, second opinion on complex cases or e-learning. In this presentation we present an expertise approach that uses teleconsul...

In the late nineteenth century anatomists claimed a new technique— slicing frozen corpses into sections—translated the three-dimensional complexity of the human body into flat, visually striking, and unprecedentedly accurate images. Traditionally hostile to visual aids, elite anatomists controversially claimed frozen sections had replaced dissection as the “true anatomy.” Some obstetricians ado...

The extrusion of section from round billet poses a great challenge for theoretical modeling of the process using upper bound method. The greatest difficulty in three-dimensional upper bound method is to determine kinematically admissible velocity field. The SERR (Spatial Elementary Rigid Region) technique is fairly applicable for analyzing extrusion of sections having re-entrant corners. A modi...

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...
