On the Ayerza's syndrome in pulmonary artery sclerosis

In his article "On the diagnosis of pulmonary artery sclerosis (Ayerza's disease)“ (Kaz. med. journal, No. 7, 1938) we have already pointed out that it is impossible to put an equal sign between the so-called. Ayerza's disease and pulmonary artery sclerosis. If sclerosis of the pulmonary artery, which is found on the section quite often (according to Moshkovich in 6.5% of all cases) was always accompanied by such a vivid clinical symptom complex as described by Ayerza, it would not be difficult to diagnose it. In fact, a lifetime diagnosis of pulmonary artery sclerosis is very rare. This is due to the fact that pulmonary artery sclerosis is not always accompanied by the clinical picture described by Ayerza, so we have to talk not about the disease, but about Ayerza's syndrome.
