Performance evaluation of a new Stago automated haemostasis analyser: The STA R Max 2.

Introduction: The STA R Max 2 is a new coagulation analyser developed by Diagnostica Stago, able to perform clotting, chromogenic and immuno-turbidimetric tests. A pre-analytical module build into the cap-piercing needle performs the sample integrity verification (sample tube filling and measurement of haemolysis, icterus, lipaemia). The STA R Max 2 analyser incorporates an accreditation program tools to assist technical validation of the analyser.

[Large granular lymphocytic leukemia CD3CD56: a challenge for the biologist and the physician].

Large granular lymphocyte leukemia (LGL) are chronic lymphoproliferative disorders classified into three main groups: T-cell LGL leukemia (T-LGL), aggressive NK-cell leukemia and chronic lymphoproliferative disorder of NK cells (NK-LGL). Patients with LGL leukemia exhibit chronic (>3 months) and moderate (<1G/L) to substantial monoclonal expansion of large granular lymphocytes in the peripheral blood. Cytologically, large granular lymphocytes are medium to large cells which are further characterized by an eccentric nucleus and a slightly basophilic cytoplasm containing azurophilic granules.

Risk factors for infection and molecular typing in patients in the intensive care unit colonized with nosocomial Enterobacter aerogenes.

Objectives: To determine the frequency of colonization by Enterobacter aerogenes in patients in the intensive care unit (ICU) for more than 48 hours and to evaluate the risk factors for infection in patients colonized by this bacteria.

Design: An 8-month prospective study.

Setting: A 12-bed medical-surgical ICU in a 450-bed, university-affiliated, tertiary-care hospital in Belgium.
