Summary
Severe pectus excavatum (PEX) can cause syncope due to right ventricular compression. This case highlights PEX and anemia as potential causes of syncope when other conditions are ruled out.
Area of Science:
- Cardiology
- Thoracic Surgery
- Medical Diagnostics
Background:
- Pectus excavatum (PEX) is a common congenital chest deformity.
- Severe PEX can compress the heart and great vessels, leading to symptoms like syncope.
- Syncope from right ventricle compression in PEX is rare but impactful.

Data Reporting and Recording
5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Behavior of Concrete Under Compressive Load
651
Concrete exhibits specific behaviors under different compressive loads. Understanding this is crucial for understanding its structural integrity. When concrete undergoes uniaxial compression, it tends to develop cracks that run parallel to the direction of the force. These parallel cracks stem from localized tensile stresses that occur perpendicular to the compression direction. Additionally, angled cracks may appear due to the formation of shear planes.

Reporter Genes
13.4K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
