Measurement of erythemal response to ultraviolet radiation by "monochromatic" photography.

The main early color change induced by ultraviolet light consists of a decreased oxyhemoglobin reflectance. A method is presented in which the skin together with a calibrated gray scale is photographed using an interference filter with a peak transmission at 540 nm, the region of the specific absorption bands of hemoglobin. On the processed photographs the irradiated skin can then be compared with the calibrated scale and thus the degree of ultraviolet erythema calculated.

[Epidermolysis bullosa dystrophica inversa, a review and case report].

An additional case of epidermolysis bullosa dystrophica inversa is reported. A review of the literature shows that until now reports about probably 15 patients from seven families were published, although the first 13 patients were not investigated by electron microscope [3]. By blistering beneath the basal lamina similar to the Hallopeau-Siemens type these patients develop bullae predominantly at the trunk and the inverse sites of the axillar and genitoanal regions continuously or at close intervals starting shortly after birth. The mucous membranes of the mouth, the esophagus, and the cornea and conjunctiva of the eye are very often involved. By bacterial infection of the skin lesions the patients develop hpochrome anemia. The web-like structures in the esophagus following blistering can be successfully treated by careful dilatation because of the low tendency to scar formation. An autosomal recessive mode of inheritance seems to be most likely.

[Phototoxic and photoallergic reactions of the skin (author's transl)].

Phototoxic and photoallergic reactions of the skin are certainly not very common, but, on the other hand, the complete list of medicinal substances which are accused of causing them is extremely extensive. For this reason, dispensing with many details, an attempt is made to present the basis of such reactions. After irradiation with longwave ultra-violet light, which alone would not have produced inflammation, a reaction occurred through the agency of many drugs which can proceed according to a toxic or allergic mechanism.
