Hemodynamic profile of pulmonary arterial hypertension in a Tunisian center.

Introduction: Pulmonary hypertension (PH) management can only be conceived in a specialized center. We aimed to report the experience of a Tunisian ICU about PH invasive hemodynamic exploration and to describe consequent therapeutic decisions.

Methods: Retrospective descriptive study including all patients admitted to the medical ICU of Abderrahmen Mami Hospital for right heart catheterization (RHC), between 2005 and 2019 as part of the investigation of PH.

Beneficial of adding Tocilizumab to standard care in critical forms of Covid-19 pneumonia: Study on paired series.

Introduction: Tocilizumab (TCZ), a humanized monoclonal antibody directed against interleukin-6 (IL-6) receptors, has been tried in various studies as a Covid-19 therapy with controversial results.

Aim: To evaluate the effectiveness of adding TCZ to standard care (SC) in critical Covid-19 patients.

Methods: it was designed retrospectively as a comparative study on two paired series of critical patients affected with Covid-19: the 1st group received TCZ plus SC versus a 2nd group which received only SC.

Severe pneumococcal community-acquired pneumonia admitted to medical Tunisian ICU.

Streptococcus pneumoniae is the most common cause of community-acquired pneumonia (CAP). There are no available data about this disease in Tunisian intensive care patients. The objective of this study is to describe the clinical and microbiological features of pneumococcal CAP and determine the prognostic factors.

Acute pulmonary embolism: epidemiologic and tomodensitometric study.

Background: Acute pulmonary embolism is a common disease with substantial morbidity and mortality in untreated patients. It requires an urgent positive diagnosis.

Aim: To assess the prevalence of acute pulmonary embolism and calculate the sensitivity and specificity of multidetector CT for the diagnosis of acute pulmonary embolism in a hospital specialized in cardio-thoracic diseases.
