Context:

• Reports five cases of toxic methemoglobinemia.
• Four cases in newborns, one in a toddler.
• Identifies acute gastroenteritis, carrot soup, and spinach as etiological factors.

Purpose:

• To present cases of toxic methemoglobinemia.
• To discuss the diagnosis and treatment of this condition.

Summary:

• Five cases of toxic methemoglobinemia are presented, with four occurring in newborns and one in a toddler.
• Etiological factors identified include acute gastroenteritis, consumption of carrot soup, and spinach ingestion.
• The abstract reviews diagnostic methods such as gasometric diagnosis and hemoglobin spectrophotometry, and highlights treatment with methylene blue.
