[Potential diagnostic role of renal sonography in acute post-streptococcal glomerulonephritis (APSGN) "with minimal urinary signs"]. / Possibile ruolo diagnostico dell'ecografia renale nella Glomerulonefrite acuta post-streptococcica (G.N.A.P.S.) "a segni urinari minimi".

The Authors studied 8 patients with an average age of eight and a half affected with G.N.A.P.S. with "minimum urinary signs". A renal ecography carried out in a diagnostic approach showed in 7 cases out of 8 the constant presence of an increased volume of the kidney, associated with hyperecogenicity and 3rd degree thickening of the cortical. They conclude that this information could be of great use for a rapid diagnostic orientation in forms of G.N.A.P.S. "with minimum urinary signs".

[Fetal polyuria and decrease of electrolytes in amniotic fluid as principal markers of neonatal Bartter's syndrome]. / La poliuria fetale e la diselettrolitemia del liquido amniotico quali principali markers della varietà neonatale della sindrome di Bartter.

The above mentioned after a careful investigation of the modern pathogenic aspects of Bartter's syndrome, evaluated the markers that are useful for the prenatal diagnosis of Bartter's syndrome, they pointed out, as in both cases the presence of polyhydramnios not associated with ecographically detectable fetal malformations, elevated chloride in the amniotic fluid, accompanied in one case by increased levels of aldosterone, in the other case by the increase of K, as being reliable markers for the prenatal diagnosis of these conditions.
