[Two cases of superficial pemphigus induced by pyritinol (author's transl)].
Pyritinol is presently prescribed in rhumatoid polyarthritis because of its structural analogy to D-penicillamin. Only benign cutaneous side effects had been mentioned up to now. We report two cases of pemphigus occurring during pyritinol therapy given in one case for rhumatoid polyarthritis, in the other case for memory deficiency. Clinical aspect was that of a superficial pemphigus. The histologic picture was in some instances that of a superficial acantholysis, and in other instances, that of an eosinophilic spongiosis. Definite proof of pemphigus was shown by presence of anti-intercellular substance antibodies in the serum and in the skin of both patients.

[HL-A system in psoriasis; study of 31 families (author's transl)].
31 families with at least two psoriatic members, including sometimes three generations (4 families) have been studied looking for HL-A markers. They include 80 affected (45 females, 35 males) and 75 healthy persons. BW 17 has been found present in 58 p. 100 of the unrelated patients, versus 7 p. 100 only in the normal population (p less than 10-9). Relative risk (R.R.) for the people bearing BW 17 is 38.34. Increase of B 13 is slight and non significant. BW 16, BW 37, BW 27 are within normal range. B 12 (R.R. :0.36) seems to have a protecting effect. B 8, B 14 are also decreased. Study of way of genetic transmission favours existence of a dominant gene of susceptibility frequently associated with BW 17 and particularly with haplotype A 1, BW 17. But other genetic or environmental factors may also play a role.
