[Phototoxic reactions to 8-methoxypsoralen as occupational dermatosis].
The case history of a 50-year-old assistant pharmacist, who had been working with 8-methoxypsoralene (8-MOP) without any protection, is discussed. Shortly after this work, he was exposed to sunlight. Within 72 h he developed a typical local reaction with painful erythema and vesiculation on the back of both hands, followed by hyperpigmentation a week later. Light testing on skin dusted with 8-MOP resulted in the same clinical picture. Histopathological examination of a lesion showed the characteristics of a phototoxic dermatitis. Guidelines for the prevention of complications in those who are professionally exposed to 8-MOP are emphasized.

Sensitivity of gonococcus strains isolated in Rotterdam to epicillin, ampicillin, penicillin and tetracycline.
Quantitative determinations of the sensitivity to epicillin, ampicillin, penicillin and tetracycline were carried out for 67 gonococcus strains isolated from 67 males with urogenital gonorrhoea, and 38 strains isolated from 38 females with urogenital/rectal gonorrhoea. The results of the sensitivity determinations for ampicillin, penicillin and tetracycline were compared with the findings of a previous investigation. It was found that the gonococcus strains isolated from males had become slightly less sensitive to penicillin between 1971-1972 and 1976. The penicillin and tetracycline had not changed during this period. It was also striking that the in vitro activity of epicillin for strains isolated both from males and females was significantly greater than that of ampicillin.

Treatment of urogenital/rectal gonorrhoea in males and females with epicillin in combination with probenecid.
This paper describes the results of treatment of 124 patients (78 male and 46 female) with urogenital/rectal gonorrhoea with epicillin (3.5 g orally) in combination with 1 g of probenecid (instant therapy). High cure rates were found for both the male (98.6%) and female patients (100%). Serious drawbacks of this treatment are a high frequency of postgonococcal urethritis (45.6%) and a short-lived increase in the frequency and looseness of faecal discharge in a considerable amount of patients (6.8% in the male and 22.7% in the female patients).

First experiences with single-dose treatment of vaginal trichomoniasis with carnidazole (R 25831).
This paper reports the results of treating 152 women with carnidazole, a new trichomonacidal drug. They were divided into two groups. The first comprised 91 patients who were treated with 2 g, while the second group comprised 61 patients who were treated with 1-5 g carnidazole in a single oral dose. Defaulter rates were 6-6% for the first group and 13-1% for the second. Of the remaining 85 patients in the first group, 76 (89-5%) were negative at the first follow-up one to three weeks after treatment, three (3-5%) were considered to be treatment failures, and six (7-0%) were considered to be reinfected. Of 53 women treated with 1-5 g, 39 (73-6%) were negative at first follow-up, eight (15-1%) were considered to be treatment failures, and six (11-3%) were considered to be reinfected. The difference between the number of patients cured in both groups is statistically significant. Fourteen patients experienced side-effects, but these were of little significance. Carnidazole given in a single oral dose of 2 g in 16 women did not cause consistent changes in any of the haematological and biochemical parameters studied.

Penicillinase-producing strains of Neisseria gonorrhoeae isolated in Rotterdam.
This appears to be the first report of the isolation of a penicillinase-producing strain of Neisseria gonorrhoeae in the Netherlands. The presence of a penicillinase-producing gonococcal strain (PPGS) was demonstrated in two of a group of three patients with gonorrhoea. In addition, a penicillin- and ampicillin-sensitive gonococcus strain was isolated from all three patients. The PPGS was most probably imported into Holland from the Philippines. The epidemiological and clinical findings and the results of treatment of infection with this PPGS are discussed.
