For some years, we have been engaged in studying the etiologic factors in psoriasis. As no data have been hitherto published on the more important inorganic salt content of the blood in this condition, we thought this worthy of investigation. We examined the blood of patients with psoriasis for calcium, magnesium, potassium and phosphorus. The amounts determined all fall within normal limits. We likewise analyzed the blood in some cases of eczema, urticaria and several other dermatoses. The findings in these cases were likewise normal.
In a previous communication1 in which the more important nonprotein nitrogenous bodies of the blood were studied, the data presented indicated an unusual incidence of hyperuricemia in many cases of eczema and pruritus.
The literature on the subject of inorganic salts in the blood diseases of the skin is quite meager. Levin and Kahn2 reported a few calcium determinations in various skin diseases.
