Dermatologic Advances: 1968-1969

Outstanding advances relating to dermatology for the period 1968 to mid-1969 include discovery of an enzyme-lack for removing ultraviolet damage in xeroderma pigmentosum, the promise of viral control by enzyme inducers and new drugs, finding smudged and shattered chromosomes in untreated psoriasis, radiologic cure of Hodgkin's disease, synonymy of the virus implicated in infectious mononucleosis with that recovered from Burkitt's lymphoma, similarity of Langerhan's cell and that found in histiocytosis-X, deep corneal dystrophy in X-linked ichthyosis, widespread application of immunofluorescent techniques in investigation of pemphigus, pemphigoid, lupus erythematosus, and vasculitis, qualitative defect of leukocytes in granulomatous disease of childhood, real effectiveness of paraaminobenzoic acid (PABA) and its salts in ethyl alcohol for light-sensitivity disorders, a simple and useful culture medium responding with color change when griseofulvin-treatable organisms are present, and many others.
