Effects of temperature on ultraviolet-induced erythema of human skin. I. Convective cooling.

Convective cooling of human skin to 20 degrees C or less for 1 h immediately after ultraviolet-B irradiation (UV-B, 290-320 nm) results in a significant increase in erythemal threshold when erythema was observed at 4-6 h postirradiation. Cooling the skin immediately before UV-B irradiation showed no consistent influence on the erythema response. In neither case was an effect of cooling on erythemal threshold apparent when erythema was evaluated at 24 h postirradiation. These effects may be due to alterations in the diffusion kinetics of chemical mediators of inflammation, modification of vascular responsiveness, or reflect changes in temperature-dependent cellular repair or expression of UV-induced damage.

Reticular erythematous mucinosis syndrome. Report of two cases.

Two female patients had eruptions with the morphologic and histologic features of reticular erythematous mucinosis syndrome. However, both cases had features that differed from previous descriptions. In one case the eruption developed three to four weeks after a single erythemogenic sun exposure and faded after two to three weeks. The rash could be reproduced by exposure to ultraviolet B (UVB) or UVC radiation. In the other patient, the eruption involved the arms and face and spared the trunk, which is a more characteristic site of involvement; it was associated with a history of exacerbation following sun exposure, but the rash could not be reproduced on phototesting.
