Quinidine photosensitivity.

A 55-year-old woman developed a dermatitis confined to light-exposed areas while taking quinidine gluconate, warfarin sodium, furosemide, spironolactone, and digoxin after cardiac surgery. Phototesting indicated a normal erythematous response to 290- to 320-nm ultraviolet radiation, but she developed erythema from 6 joules/sq cm of 320- to 400-nm radiation (ultraviolet A [UV-A]), a much lower dose than needed to produce a reaction in normal individuals. Two days after she discontinued quinidine and warfarin, phototesting showed no reaction to as much as 20 joules/sq cm of UV-A. One week after resuming quinidine (but not warfarin), she again reacted to 8 joules/sq cm of UV-A. No reactivity was elicited when the preparation was applied to the skin or injected into the dermis either with or without subsequent UV-A irradiation.

Modified Goeckerman therapy for psoriasis. A two-year follow-up of a combined hospital-ambulatory care program.

Two groups totaling 162 patients hospitalized for modified Goeckerman treatment of severe psoriasis were matched for sex, age, and season of admission and followed up for two years after discharge. One group remained hospitalized throughout their average 20.8-day course; the other half was hospitalized 14 days, then transferred to an ambulatory center for the remainder of a course averaging 20.8 days. No difference was detected between the groups in the duration that improvement equaled or exceeded progress achieved at discharge. The percentage of patients remaining continuously improved after discharge was 80% at one month, 55% at six months, 40% at 12 months, and 20% at 24 months. rates of relapse requiring readmission or alternate therapy were also similar: 75% had not relapsed by 12 months and 60% had not relapsed by 24 months.

Hydroa vacciniforme: induction of lesions with ultraviolet A.

Hydroa vacciniforme is a rare photosensitivity disorder with onset in childhood. The distinctive lesion is a vesicle which heals with scarring. We report a case of hydroa vacciniforme in which an abnormal minimal erythema dose to wavelengths of 322 to 370 nm within the ultraviolet A (UVA) range was demonstrated. Vesicles could be induced only with multiple exposures to UVA. Increased tolerance to UVA erythema was induced by multiple UVB exposures, although tanning was poor. Of note were the presence of several halo nevi and a history of the loss of ability to tan. The clinical features and appropriate laboratory evaluation of hydroa vacciniforme are reviewed.
