Agenesis of the Left Pulmonary Artery Associated With Hypoplasia of the Homolateral Lung: An Unusual Cause of Recurrent Respiratory Infection.

Agenesis of the left pulmonary artery represents a rare malformation, accounting for a small fraction of all cases of congenital heart disease. It is characterized by the absence of the left pulmonary artery, which can lead to respiratory and cardiac complications. This anomaly can appear on a standard chest X-ray, but it must be confirmed by a chest CT scanner, which makes it possible to visualize the absence of the left pulmonary artery and the associated parenchymal anomalies.

Diagnostic yield of viral multiplex PCR during acute exacerbation of COPD admitted to the intensive care unit: a pilot study.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is one of the leading causes of admission to the intensive care unit, often triggered by a respiratory tract infection of bacterial or viral aetiology. Managing antibiotic therapy in this context remains a challenge. Respiratory panel molecular tests allow identifying viral aetiologies of AECOPD.
