[Methemoglobinemia in acute diarrhea in infants].

8 cases of methemoglobinemia are observed in infants of 28 days to 138 days of age, who have all acute diarrhea. They are divided in two groups. --4 infants who have eaten for a long time a rich nitrate and nitrite content carrot soup. --4 cases of severe diarrhea with probable endogenous nitrification due to microbial proliferation. The methemoglobinemia level is here not very high and represents more a witness that an alarming symptom. Those infants are compared with 10 infants who have diarrhea without methemoglobinemia. Symptoms and treatment of methemoglobinemia are revisited.
