Background:
Infectious mononucleosis is usually a self-limiting illness, but can be rarely associated with complications.
Case Characteristics:
A 17-year-old boy with Epstein-Barr virus related infectious mononucleosis and cold antibody-mediated autoimmune hemolytic anemia with incidentally noted multiple pulmonary nodules.
Observations:
Nodules regressed over the next few weeks without specific therapy.
Message:
Pediatricians need to be aware of this rare clinical presentation of infectious mononucleosis so that further invasive testing can be avoided.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
