COVID-19 Presenting as Lupus Erythematosus-Like Syndrome.

The 2019 coronavirus disease (COVID-19) infection had newly emerged with predominant respiratory complications. Other extrapulmonary features had been recently described. Here, we describe a COVID-19 patient presenting with multiorgan involvement mimicking systemic lupus erythematosus.

[Measurement of angiotensin-I-converting enzyme in the blood: help for method validation].

Blood angiotensin-converting enzyme (ACE) assay is now realized by the determination of enzyme activity on synthetic substrate, mostly furylacryloyl-phenylalanyl-L-glycyl-L-glycine (FAPGG). The matrix can be serum or heparin-plasma, with or without a separator; the assay developed on serum or plasma is not adapted to other matrix such as cerebrospinal fluid where the ACE activity is much lower. This assay has been adapted on a number of automated biochemistry analyzers with the specifications of the supplier of reagents, sometimes with modification of volumes or times for analysis.

Lactate POCT in mobile intensive care units for septic patients? A comparison of capillary blood method versus venous blood and plasma-based reference methods.

Aim Of The Study: We evaluated if the StatStrip Xpress Meter, a Lactate point of care testing (POCT) handled device, could be a valuable tool in the mobile intensive care units (MICU) to assess the severity of septic patients.

Methods: We first investigated POCT analytical performance, then, using samples collected from 50 identified septic patients admitted to the intensive care unit (ICU), we compared lactate values obtained with the device to those obtained with four central laboratory analysers: one whole blood and three plasma-based methods.

Results: Results were compared by least squares regression, Bland-Altman plot and by comparing concordance within clinically relevant lactate ranges.

Interest of fecal calprotectine dosage in inflammatory bowel diseases, state of the art and perspectives.

Inflammatory bowel diseases are chronic diseases that result from an inflammation of the intestinal wall. They are suspected in any patient presenting with intestinal symptoms. Until recently, diagnosis was mainly based both on clinical and endoscopic arguments.

Occupational blood exposure among health care personnel and hospital trainees.

Blood and body fluid Exposure is a major occupational safety problems for health care workers. Therefor We conducted a descriptive and retrospective study to identify the characteristics of blood exposure accidents in health care settings which lasted five years (2005-2009) at the two university hospitals of Sfax. We have 593 blood exposure accidents in health care settings 152 (25.
