Decrease in neutrophils observed in vivo in psoriatics after PUVA therapy.

In 56 patients leucocyte and differential counts were done before and at weekly intervals during PUVA treatment of chronic recalcitrant psoriasis. A statistical significant (P less than 0.01) decrease in the percentage of neutrophils was observed during the first week of the PUVA therapy. This observation could be closely related to the clinical clearing of psoriasis (P = 0.02). The effect of PUVA therapy in psoriasis may be due to a decrease in the number of immunocompetent neutrophils demonstrated in psoriatic lesions.

Prevalence of vitiligo. Epidemiological survey on the Isle of Bornholm, Denmark.

The prevalence of vitiligo was 0.38% in 47,033 people in a representative region in Denmark. Both sexes were equally affected. No significant difference was found in the distribution of 179 patients with vitiligo among five municipalities or between urban and rural districts. The age-specific prevalence increased from 0.09% under the age of 10 years to 0.90% in the age group 60 to 69 years. After the age of 70, the prevalence declined. This fall might reflect an increased incidence of vitiligo during the past few decades. The number of new cases of vitiligo increased steadily with advancing age, its onset being most often between the ages of 40 and 60 years. It is assumed that the prevalence of vitiligo in Denmark applies also to the northwestern part of Europe.

Cutaneous sarcoidosis treated with methotrexate.

Sixteen patients with cutaneous sarcoidosis, 15 of whom also had involvement of other organs, were treated with methotrexate (MTX) orally once a week in an open study. The treatment period was from 1 to 72 months (mean 23 months). In 12 patients the skin lesions cleared, and in 3 of 4 patients who had sarcoid uveitis this cleared as well. The chest X-ray of 6 patients showed no corresponding improvement in pulmonary changes or in hilar adenopathy. Ten patients suffered side effects, usually nausea on the day MTX was taken. Two had transiently increased transaminase levels. Treatment was discontinued in 2 patients due to nausea. It is concluded that MTX is a useful alternative to systemically administered glucocorticoids in the treatment of disfiguring cutaneous sarcoidosis and sarcoid uveitis. The effect of MTX on hilar adenopathy and pulmonary sarcoidosis is uncertain.

Photodynamic inactivation of verrucae vulgares. I.

Verrucae vulgares (v.v.) stained in vivo and in vitro with 0.1% and 1% proflavine in 100% dimethylsulphoxide (DMSO) and 0.1% and 1% neutral red in 100% DMSO were examined grossly and by fluorescence microscopy. Light transmission studies were made using both whole v.v. embedded in methacrylate and 5 micrometer frozen sections. The dyes were seen to penetrate to the epidermal and dermal structures in the in vivo stained v.v. and accumulate in the cell nuclei. The average concentration of neutral red in the v.v. was estimated to be 2 X 10(-5) M. The concentration of proflavine was lower than that, but exceeded 10(-6)M. There was diffuse staining throughout the in vitro stained warts. From 400-600 nm the warts were penetrated by at least 1% of the light directed toward their surfaces.

Photodynamic inactivation of verrucae vulgares. II.

Photodynamic inactivation therapy, consisting of a double-blind, paired comparison treatment schedule, was used in treating 56 patients for recalcitrant, symmetrical verrucae vulgares. 0.1% proflavine in 100% dimethylsulphoxide (DMSO) and 0.1% neutral red in 100% DMSO were used as active dyes, and 1% picric acid in 100% DMSO and 1% color ruber in 100% DMSO and 1% color ruber in 100% DMSO served as corresponding placebos. A Westinghouse sunlamp and black light were used to irradiate the warts dyed with proflavine and its placebo, and the warts dyed with neutral red and its placebo were irradiated with an ordinary light bulb (Osram 588597). 50 patients completed the treatment. 10 of the 27 patients treated with proflavine and 10 of the 23 patients treated with neutral red were cured by the end of an 8 week period, with the warts disappearing simultaneously from the actively as well as the placebo-treated side. Complement fixing antibodies against wart virus were detected in one of the cured patients and 2 who were treatment failures.

Transmission of Bucky (Grenz) rays through human scalp hair.

The shielding effect of various types of human hair and the influence of a shampoo on the transmission of grenz rays were determined by ionization chamber measurements. The mean transmission proved to be 53.7% with clean hair and 48.1% with hair shampooed one week before. P less than 0.05 (n = 50) (Pratt's test). A relationship was found between weight of hair layer and transmission. In clinical practice, the thickness of the hair should be assessed, and the normal skin dose multiplied by 1.5 for patients with a thin hair layer, by 2 in the case of a medium, and by 3 in the case of a thick hair layer.

Immunological studies in sarcoidosis: a comparison of disease activity and various immunological parameters.

We found it valuable to separate the heterogeneous types of sarcoidosis into more homogeneous groups on the basis of activity and duration of the disease. This view is supported in the present study by the finding of a marked depression of T-cell function in patients with chronic-active sarcoidosis. Patients with acute or chronic-inactive disease had only moderately depressed T-cell function as measured by tuberculin skin test and DNCB index. These results are in agreement with those of some previous investigations. The remainder of the abnormal findings, particularly low total number of circulation T lymphocytes, elevated serum IgG levels, and presence of autoantibodies, could not be correlated to disease activity, extent of the disease, or T-cell function. We have found no explanation for the presence of autoantibodies but suspect that they may be nonspecifically related to the disease process.

Clinical trial comparing hydrocortisone 17-butyrate to betamethasone 17-valerate in a series of patients with eczematous skin diseases.

A randomized, double-blind, left-right comparative study was carried out to compare the value of hydrocortisone 17-butyrate with that of betamethasone 17-valerate in the treatment of eczematous skin disorders. In a series of 23 patients with such disorders, no differences between the two preparations was demonstrated with regard to effectiveness.
