Introduction: Heritable conditions causing aldosterone deficiency (hypoaldosteronism) or target-organ resistance (pseudohypoaldosteronism, PHA) can lead to life-threatening salt-wasting crises in early life. Prompt evaluation and correct interpretation of aldosterone and renin are crucial to guide differential diagnosis and further testing. Here we report on the similarities and differences of two neonates presenting with salt-wasting: Patient (P1) due to PHA ...

The activation of the hypothalamic-pituitary-gonadal (HPG) axis during the first six months of life in boys marks the period of “mini-puberty”. It is characterized by a surge of gonadotropins, testosterone, and an increase of Sertoli cells and germ cells, crucial for future reproductive capacity. Boys with severe congenital hypogonadotropic hypogonadism (CHH) often present with undescended testes and micropenis and lack mini-puberty, leading to impaired responses t...
