A @entity1 with @entity28178 is referred. The diagnosis was delayed and complicated as her parents didn't tell us that her sister had been affected by the same illness. The @entity1 was born after premature rupture of membranes at 34 weeks. At birth, her conditions were satisfactory. The general conditions of the @entity1 gradually worsened and, though she regularly ate @entity1 pastorized bank milk, she didn't gain any weight. After 13 days she appeared dehydrated with marbled dry skin and haloed eyes, @entity2421 and hyporeflexic. Her suction became more and more weaker, with frequent regurgitations and @entity391 . Laboratory tests pointed out @entity2753 (110 mEq/l) and @entity4144 (6.8 mEq/l). We were able to establish diagnosis of @entity28178 measuring plasma concentrations of @entity1369 (> 5000 pg/ml), 17 @entity35829 (normal) and corticosteroids (normal). The @entity1 was then supplemented with @entity1372 chlorure. A gradual improvement of general conditions took place. We assumed that both childrens and mother were affected by a milder form of @entity28178 , characterized by an autosomal dominant way of transmission. We found high levels of @entity1369 with normal levels of blood salts also in the sister and mother @entity1 's. After the neonatal period, @entity28178 can be only suspected in case of positive family history.
