چکیده

Introduction: Visual assessment of endomyocardial biopsy (EMB) specimens may result in errors due to the human factor and inability obtain quantitative data on intensity immunohistochemical (IHC) reactions severity pathological changes heart transplant. Detailed digital characterization EMB based automated or semi-automated computer-assisted morphometry improves diagnostic accuracy EMB. Objective: To develop a method algorithms for analysis quantify pathomorphological immunophenotypic myocardium patients with various types grades transplant rejection. Materials methods: We studied 257 from 56 recipients at Scientific Research Institute – Ochapovsky Regional Clinical Hospital No. 1 (Krasnodar, Russian Federation). Sections were stained hematoxylin eosin. used streptavidin-biotin determine CD68 expression images measure area expression. Results: When developing specimens, we proposed new evaluation criterion: staining coefficient (%) that is ratio total section area. created field-tested morphometric assess IHC identify relative EBM specimens. Conclusions: New criteria diagnosing rejections are improve results interpretation, but can also be analyzing other

Rapid histological changes in endomyocardial biopsy specimens after myocarditis.

The course and response to treatment in acute lymphocytic myocarditis are conventionally monitored by endomyocardial biopsy performed every 3-12 weeks. A patient with a short history (five days) of acute myopericarditis of unknown aetiology presented in cardiogenic shock with evidence of severe systolic dysfunction on the echocardiogram. The initial biopsy specimen showed histologically unequiv...

Diagnostic value of endomyocardial biopsy for endomyocardial fibrosis

Endomyocardial fibrosis (EMF) is a restrictive cardiomyopathy of unknown etiology. It is mainly prevalent in the tropical and subtropical countries. The aim of this study was to evaluate the diagnostic value of endomyocardial biopsy (EMB) for EMF, and detect the relationship between Coxsackie virus B3 (CVB3) and EMF in the Chinese patients. The right ventricular EMB was performed in 18 patients...

Anatomic Pathology / PERIVASCULAR INFLAMMATION IN TEMPORAL ARTERY BIOPSY SPECIMENS

We retrospectively compared 81 temporal artery biopsy specimens demonstrating perivascular inflammation without evidence of temporal arteritis and 76 specimens demonstrating no inflammation. Patients with perivascular inflammation included 43 women (mean age, 71.2 years). Nineteen patients met the 1990 American College of Rheumatology (ACR) criteria for the diagnosis of temporal arteritis. All ...
