Agreement of cardiac index measurements between ultrasonic cardiac output monitor and transthoracic echocardiography in neonates.

Objectives: To evaluate the agreement of cardiac index (CI) calculated by Ultrasonic sonic cardiac output monitor (USCOM) and transthoracic thoracic echocardiography (TTE) in order to know if we can recommend USCOM in our pediatric intensive care unit (PICU).

Design: Prospective observational evaluative study carried out over a period of 3 months Setting: PICU at children's hospital in Tunis Participants: All newborns without tracheostomy or a known congenital heart disease, admitted to the PICU during the study period were enrolled.

Interventions: Paired and consecutive measurements of CI were obtained in all patients with both technologies.

Critically ill infants with SARS-COV-2 delta variant infection.

Background: SARS-CoV-2 is described to cause mild to moderate symptoms in children. To date, clinical data and symptoms of the Delta variant in pediatric patients are lacking.

Aim: To describe clinical characteristics and outcomes of infants admitted in the pediatric intensive care unit (PICU) during the period of Delta variant predominance.

Implementation of a prospective study for enhancing surveillance of invasive bacterial infections in North Africa.

Objectives: We implemented a project named MENINGSTOP in three countries of North Africa (Algeria, Morocco and Tunisia). The main objective was to use real-time PCR to detect, identify and type the three main agents (Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae) responsible for invasive bacterial infections (IBI).

Methods: The protocol of WHO and US CDC for real-time PCR was used to detect and type the three bacterial agents in clinical samples.

First Tunisian Cluster Admissions of Critically Ill Patients with Multisystem Inflammatory Syndrome in Children (MIS-C).

Background: Multisystem inflammatory syndrome in children (MIS-C) is a new emerging severe disease that is temporally related to previous exposure to coronavirus infection disease (COVID-19).

Aim: To describe the clinical features, laboratory findings, therapies, and outcomes for the first Tunisian cluster admissions of critically ill children with severe MIS-C.

Methods: Retrospective study conducted from November 01 to November 30, 2020According to the WHO definition case, we included eight children aged less than 15 years who were admitted to our pediatric intensive care and met MIS-C criteria.

Congenital urethrocele in children. A case report.

Methods: The evaluation covered the period of 2012-2015 and used different data sources to measure indicators related to data quality and completeness, representativeness, timeliness, simplicity, acceptability, flexibility, stability and utility.

Results: During the evaluation period, 485.

Predictors of Mortality in Mechanically Ventilated Critical Pertussis in a low Income Country.
