Lichen urticatus, a papular form of urticaria in children, is peculiarly resistant to all the methods of treatment usually advocated. As a result of clinical experience with the use of parathyroid extract (Collip1), I believe that an effective method has been found to alleviate this stubborn disease.
Lichen urticatus probably belongs in the group of sensitization dermatoses and is possibly fundamentally dependent on a positive and negative relationship of ion concentration. One of the elements in this ion interplay is calcium.
The use of calcium in the urticarial group of disorders has long been advocated, with conflicting opinions as to its results. It has been shown recently that the administration of a dose of from 5 to 10 grains (0.3 to 0.65 Gm.) of calcium lactate does not cause any appreciable increase in the calcium content of the blood, but that with massive doses of 1 or 2 drachms
