COVID-19 epidemic in the Seine-Saint-Denis Department of Greater Paris: one month and three waves for a tsunami.

Introduction: Worldwide, the COVID-19 epidemic has put health systems to the test. The excess mortality is partly due to the influx of patients requiring hospitalization and intensive care. We propose that the chronology of epidemic spread gives a window of time in which hospitals can act to prevent reaching capacity.

Clinical features of 1487 COVID-19 patients with outpatient management in the Greater Paris: the COVID-call study.

Clinical features of COVID-19 have been mostly described in hospitalized patients with and without ICU admission. Yet, up to 80% of patients are managed in an outpatient setting. This population is poorly documented.

[Impact of extreme temperatures on primary care requirement in France: the CHAUFOS Study (2010-2018).].

Introduction: The health impact of cold and hot waves is major. Nevertheless, the respective impact of extreme high and low temperatures remains controversial.

Method: The daily number of (1) patients managed by SAMU 93 dispatching centre – primary care requirement indicator, (2) Mobile Intensive Care Unit (MICU) interventions – patient severity indicator and (3) number of deaths have been recorded.

[Impact of the Air Quality on Health - Analysis of the activity of a SAMU-Center 15 in Paris area - the IQUASS Study].

Introduction: The atmospheric pollution is a growing public health problem. The highly urbanized regions such as Paris area seem particularly exposed. However, the overall health impact is poorly documented.

Usefulness of hand-held ultrasound devices in out-of-hospital diagnosis performed by emergency physicians.

Objective: To evaluate the usefulness of ultrasonographic examinations as a diagnostic tool for emergency physicians in out-of-hospital settings.

Methods: Prospective study performed in a French teaching hospital. Eight emergency physicians given ultrasound training for out-of-hospital diagnosis of pleural, peritoneal, or pericardial effusion; deep venous thrombosis; and arterial flow interruption.
