Topical treatment of extended alopecia. Intralesional steroid--Kromayer lamp.

Two groups of patients with subtotal to universal areate type alopecia were serially treated, 6 with intralesional triamcinolone acetonide suspension and 6 with contact irradiation by ultraviolet light from a high-pressure mercury-arc source with a quartz envelope (Kromayer lamp). The treatment was limited to one half of the scalp while the untreated half served as a control. Triamcinolone acetonide suspension gave in 2 of the 6 treated patients a temporary stimulating effect on hari growth; later, however, hair growth inhibition was noted in 3 patients. Contact irradiation with ultraviolet light from a Kromayer lamp gave in 4 of the 6 treated patients a stimulatory effect upon hair growth, but did not seem to initiate it.

Treatment of alopecia areata with DNCB--an immunostimulation?

Ten patients with long-standing areate type alopecia totalis were sensitized with 1-chloro, 2, 4-dinitrobenzene (DNCB). Following sensitization they were painted once weekly on a 40 X 20 mm area of the vertex with DNCB in acetone, in concentrations adjusted to the allergic response. After 7 weeks, growth of hair was seen in the painted area in 3 patients and after 8 weeks all over the scalp in 3 other patients.

A comparison of oxytetracycline and trimethoprim in the treatment of Chlamydia trachomatis urethritis.

The effect of trimethoprim was compared with that of oxytetracycline in the treatment of uncomplicated urethritis and/or cervicitis. Twenty-six patients treated with oxytetracycline were all microbiologically cured. Of 19 patients treated with trimethoprim, ten (53%) still harboured the chlamydia after two weeks. The superiority of tetracycline was even more pronounced following the evaluation of dysuria and discharges. 85% of the patients treated with oxytetracycline and 6% of those treated with trimethoprim had neither dysuria nor discharge after the completion of treatment. The patients who failed to be cured by trimethoprim were all successfully treated with oxytetracycline.

Occupational non-melanoma skin cancer.

Non-melanoma skin cancer is historically known to be associated with certain professions. Reporting is mandatory in Denmark when occupational exposure is suspected. In a retrospective register-based study of all cases of suspected occupational non-melanoma skin cancer reported to the Directorate of National Labour Inspection and the National Board of Industrial Injuries in Denmark in the period January 1, 1984 to December 31, 1994, we assessed the extent to which occupational exposures today are of importance in the occurrence of non-melanoma skin cancer. A total of 74 individuals (11 women and 63 men) aged 32-82 years (median 58 years) had been reported. Of these, 15 cases (20%) were approved as being occupational, 37 (50%) were rejected and 22 (30%) were either shelved or could not be further clarified. Most commonly approved were exposures such as asphalt, tar, and the like, and ionizing radiation, and localization on the arms or multiple tumours. Unexpected occupational exposure could not be identified but continued reporting is recommended in order to follow this in the future.

Congenital perceptive hearing loss and atopic dermatitis.

Two brothers were suffering from perceptive hearing loss, atopic dermatitis and mild palmophantar keratoderma. There was a predisposition to atopic disease in the maternal family, and palmoplantar keratosis as a dominant trait in the paternal family. Atopoc dermatitis and palmoplantar keratoderma separately have been reported to co-exist with hearing loss, but a combination of all three has not so far been reported.

DNA polymorphism of HLA class II genes in alopecia areata.

We investigated the DNA restriction polymorphism (RFLP) of the Major Histocompatibility Complex (MHC) class II genes: HLA-DQA, -DQB, -DPA, and -DPB in 20 Danish patients with alopecia areata (AA) and in healthy Danes. The frequency in AA of the DQB1*0301 and DQw7 associated DQB Bgl/II 4.2 kb fragment was increased to 65.0 per cent compared to 23.2 per cent in controls (RR = 6.1; p less than 10(-3)) suggesting that the previously reported associations between AA and both DR4 and DR5 is secondary to an association between AA and DQB1*0301, which codes for the beta-chain of the HLA-DQ molecule of the serologically defined HLA-DQw7 specificity. Individuals who carried both DQA1*0501 and DQB1*0301 seemed to have a further increased risk of developing AA compared to individuals carrying only one of these HLA class II genes. Analysis of the combined presence of DQB1*0301 and DPA1*0103 in AA suggests that an additive risk effect (synergism or interaction) exists between the DQB1*0301 and DPA1*0103 alleles which are situated at different HLA class II loci.
