History
Keran was born at 39 weeks since the LMP (last menstrual period) (weight 3.2 kg). Fifteen days after birth, he developed an eczematous rash on his face which was diagnosed as atopic dermatitis. Local application of hydrocortisone partly improved the cutaneous lesions. His parents report the onset of chronic diarrhoea since the age of two months.
The number of diapers used daily has significantly increased in the last few days due to polyuria (excessive excretion of urine). On the morning of presenting to the clinic Keran was unusually sleepy and unable to breastfeed. He was pale and hypotonic.
