RESUMO
We report a case of transient methemoglobinemia in an infant due to gastroenteritis. Methemoglobinemia should be suspected in infants with a history of diarrhea and cyanosis that is out of proportion to the history and clinical examination. Methemoglobinemia can be life threatening, but outcome is good when treated with IV methylene blue.

Hypereosinophilic syndrome is a leukoproliferative disease characterised by sustained overproduction of eosinophils. The three diagnostic criteria for this disorder are (1) Eosinophilia of greater than 1500 cells/ml, persisting for longer than 6 months, (2) lack of another diagnosis to explain the eosinophilia and (3) signs and symptoms of organ involvement. We report a 15-year-old boy who was diagnosed as Hypereosinophilic syndrome based on these criteria.
