Lung ultrasound for diagnosis of pneumonia in emergency department

Internal and Emergency Medicine
Antonio PaganoFiorella Paladino

Abstract

Lung ultrasound (LUS) in the emergency department (ED) has shown a significant role in the diagnostic workup of pulmonary edema, pneumothorax and pleural effusions. The aim of this study is to assess the reliability of LUS for the diagnosis of acute pneumonia compared to chest X-ray (CXR) study. The study was conducted from September 2013 to March 2015. 107 patients were admitted to the ED with a clinical appearance of pneumonia. All the patients underwent a CXR study, read by a radiologist, and an LUS, performed by a trained ED physician on duty. Among the 105 patients, 68 were given a final diagnosis of pneumonia. We found a sensitivity of 0.985 and a specificity of 0.649 for LUS, and a sensitivity of 0.735 and specificity of 0.595 for CXR. The positive predictive value for LUS was 0.838 against 0.7 for CXR. The negative predictive value of LUS was 0.960 versus 0.550 for CXR. This study has shown sensitivity, positive predictive value and negative predictive value of LUS compared to the CXR study for the diagnosis of acute pneumonia. These results suggest the use of bedside thoracic US first-line diagnostic tool in patients with suspected pneumonia.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
