Final answer:
The young boy's symptoms are consistent with post-streptococcal glomerulonephritis (PSGN), which is an immune-mediated response that can occur as a complication of a previous streptococcal infection like bacterial pharyngitis. PSGN is characterized by facial edema, coca cola urine, and pyuria. Treatment involves supportive care and close monitoring for complete recovery.
Step-by-step explanation:
Based on the symptoms described, the young boy's condition is consistent with a condition known as post-streptococcal glomerulonephritis (PSGN). PSGN is an immune-mediated response that occurs as a complication of a previous streptococcal infection, such as bacterial pharyngitis. The facial edema, coca cola urine (hematuria), and pyuria (presence of pus in urine) are all characteristic findings of PSGN. The fact that the boy did not finish the antibiotic prescription for bacterial pharyngitis may have allowed the initial infection to progress and lead to PSGN.
PSGN occurs when the immune system mistakenly attacks the glomeruli, the filtering structures in the kidneys, in response to an infection. This immune response can result in the release of inflammatory substances that cause damage to the kidneys, leading to the observed symptoms.
Treatment for PSGN typically involves supportive care to manage the symptoms, such as bed rest and a low-sodium diet to reduce fluid retention. In most cases, PSGN resolves on its own over time, but close monitoring and follow-up are necessary to ensure complete recovery.
