摘要:

AbstractBackground. To test the reliability and reproducibility of the patch test with a paraben mix, we added a second paraben mix allergen to our standard tray and compared the results achieved with these two allergens.Methods. Two hundred and fifteen consecutive patients, undergoing patch testing with a standard series, were simultaneously tested with an additional paraben mix (i.e., each patient was tested with two paraben mix allergens) supplied by two different companies.Results. Twelve patients (5.6%) showed a positive reaction to one or two paraben tests. Five patients showed a positive reaction to one paraben test (paraben‐a), and five others to the second paraben test (paraben‐b). Only two patients out of 12 with positive reactions to parabens showed a reaction with both of the two parabens.The parabens appear to be overrepresented in our study compared to other series. There was no correlation between the results of the tests with the two different parabens usedConclusions. Patch testing with a paraben mix cannot be considered an appropriate and reliable method for detecting paraben allergies. T is recommended to test routinely with a paraben screening series instead of the paraben

摘要:

AbstractBackground. Ducatalon is a bipyridylium herbicide containing a mixture of diquat and paraquat, and is used in agriculture. Adverse reactions due to contact of this compound with the skin have rarely been described.Case Reports. Two men were seen for severe pain due to extensive chemical burns in the perineal and scrotal regions, caused by leaking of Ducatalon from defective equipment used for spraying the herbicide. The lesions responded well to treatment with topical silver sulfadiazine, combined with systemic antibiotics. The damaged skin healed without scarring within a few days. The lesions have not recurred after the faulty spraying apparatus was replaced.Conclusion. Direct contact of the skin with Ducatalon may lead to severe chemical burns. Proper precautions should be taken by the personnel handling this compound, with particular attention to the integrity of the equipment used for spraying the herbicide.

摘要:

AbstractBackground. Cutaneous tuberculosis was once a relatively common skin disease in Hong Kong. Tuberculosis verrucosa cutis was the commonest type. Because the last survey was carried out 25 years ago, it was thought necessary to find out the new incidence and pattern of this important disease in this locality.Methods. A 10‐year (1983‐1992) retrospective survey on the epidemiologic and clinicobacteriologic aspects of cutaneous tuberculosis had been done in the public sector of Hong Kong. The records of the confirmed cases were retrieved for statistical analysis.Results. A total of 176 cases are included in the final analysis. This represents 0.066% of all new skin cases seen during the 10‐year period. Among these, 79.5% are erythema induratum, 6.3% lupus vulgaris, and 4.5% tuberculosis verrucosa cutis. They are further divided into true cutaneous tuberculosis (14.8%, n=26) and the tuberculide (85.2%, n=150). Among the patients with true tuberculosis, 42.3% had lupus vulgaris, 30.8% had tuberculosis verrucosa cutis, and 26.9% had scrofuloderma. Among the tuberculides, erythema induratum accounted for 93.3%.Conclusions. Cutaneous tuberculosis is now uncommon in Hong Kong. Tuberculosis verrucosa cutis is no longer the commonest type in Hong Kong as described in some textbooks. Erythema induratum is now the most common among the total cases and lupus vulgaris is the most common among the true cutaneous forms of tubercu
