25
Symptoms of Pyloric Stenosis
- Nonbilious, projectile vomiting after feeding | - Olive-shaped, nontender mobile hard mass to right of epigastrium
26
Diagnostics for Pyloric Stenosis
- US (initial) - Upper GI series shows string sign, railroad track sign - Labs: Hypokalemia, Hypochloremic Metabolic Alkalosis
27
Treatment for Pyloric Stenosis

30
How to approach Hepatitis B Serology
-Look at Surface Antigen, if positive, either acute or chronic - If Positive, look at Core Antibody - If IgM is + --> Acute - If IgG is + --> Chronic - If Negative, look at Surface Antibody - If Positive, either vaccination or recovery (distant infection) - If surface antibody is only thing positive --> vaccination - If core IgG Antibody is positive --> recovery (resolved infection)
