[Fatal nutrient deficiencies after gastric bypass].

Introduction: Bariatric surgery is a very effective treatment for obesity. After gastric bypass, micronutrient deficiencies frequently occur which can have dramatic consequences.

Case Report: We report the case of a 55-year-old woman who was admitted for psychomotor retardation, bilateral leg pitting edema and psoriasis-like rash that had been ongoing for 3 months.

No evidence of tocilizumab treatment efficacy for severe to critical SARS-CoV2 infected patients: Results from a retrospective controlled multicenter study.

To assess tocilizumab (TCZ) efficacy associated to standard of care (SOC) compared to SOC alone in severe coronavirus associated disease 2019 (COVID-19) patients. In a matched case-control study from 3 French Hospital COVID-19 Departments, 27 patients with severe COVID-19 treated with TCZ and SOC were matched for baseline epidemiological and clinical features and compared to 27 severe COVID-19 patients treated with SOC alone. Baseline characteristics of the study population were comparable between groups.

Toe-to-room temperature gradient correlates with tissue perfusion and predicts outcome in selected critically ill patients with severe infections.

Background: Microcirculatory disorders leading to tissue hypoperfusion play a central role in the pathophysiology of organ failure in severe sepsis and septic shock. As microcirculatory disorders have been identified as strong predictive factors of unfavourable outcome, there is a need to develop accurate parameters at the bedside to evaluate tissue perfusion. We evaluated whether different body temperature gradients could relate to sepsis severity and could predict outcome in critically ill patients with severe sepsis and septic shock.

[Diagnostic ultrasound in pneumothorax].

For a long time the lung has been regarded as inaccessible to ultrasound. However, recent clinical studies have shown that this organ can be examined by this technique, which appears, in some situations, to be superior to thoracic radiography. The examination does not require special equipment and is possible using a combination of simple qualitative signs: lung sliding, the presence of B lines and the demonstration of the lung point.
