[Intranodal palisaded myofibroblastome: A rare cause of inguinal lymphadenopathy].

Introduction: Lymphadenopathies are a major cause of consultation in internal medicine, with various causes of diagnosis. Unexplained persistent lymphadenopathy must be biopsied to rule out malignant tumor.

Case Report: We report the case of a 53-year-old man, with inguinal lymphadenopathy evolving for more than one year.

Chocolate intake associated with failed labeling of (99m)Tc red blood cells.

Unlabelled: Red blood cells (RBC) labeled in vivo with (99m)Tc-pertechnetate are used worldwide in nuclear medicine departments.

Methods: Here, we present a case of (99m)Tc-RBC labeling failure associated with chocolate intake in a 25-y-old woman, resulting in uninterpretable images. Because of this clinical observation, we performed in vitro RBC labeling on blood samples from volunteers after they consumed chocolate.

Influence of residual myocardial ischaemia on induced ventricular arrhythmias following a first acute myocardial infarction.

Objectives: The purpose of this study was to assess the possible effect of residual myocardial ischaemia on induced ventricular arrhythmia during programmed ventricular stimulation in survivors of a first acute myocardial infarction.

Background: Most deaths after hospital discharge for acute myocardial infarction are sudden and presumably arrhythmic. Sudden cardiac death results from a dynamic interaction of structural abnormalities and transient triggering factors.
