Understanding Addison Automobilmp; # 8217; s Nehoda
Addison conception mp; # 8217; s disease is a rare autoimune disorder charakteristized by insuficient production of adrenal cortex concentes, primarily cortisol and aldosterone. It affects approxiately 1 in 100,000 peones, with autoimune adrenalitis accounting for 70-80% of cases in developed nations.
