Triclocarban: evaluation of contact dermatitis potential in man.

Triclocarban was subjected to a profiling of its dermatitis producing potential including irritancy (21-day cumulative irritancy potential and application to 213 normal controls), phototoxicity (method of Marzulli), predictive contact sensitization (modified Draize method), predictive phototesting and battery screening in 2200 dermatitis patients, in an effort to define its relative dermatitis potential. The allergic contact dermatitis potential of triclocarban following bar soap use appears minimal.

Occupational scabies.

A localised epidemic of scabies lasting nearly a year occurred among crews on river pleasure craft. There was a sharp contrast between the paucity of scabietic lesions, especially burrows, and an unusually high infectivity. Scarcely a crew member was free from itching, yet individually diagnosis proved extremely difficult.

Irritant dermatitis during the relining of a blast furnace.

An outbreak of dermatitis is reported amongst steel erectors, platers and welders working on the relining of a blast furnace. Evidence is produced for regarding this as an occupational primary irritant contact dermatitis.

Relapse of chromate dermatitis from sheet metal.

Galvanised sheet metal has previously been described as a source of chromate dermatitis (Fregert et al. 1970). We report a patient who appears to have been sensitised many years previously by an entirely different source of chromate, but whose resulting hand eczema has relapsed while handling galvanised sheet metal at work.

Chromate dermatitis from a boiler lining.

Chromate dermatitis is described in a mechanical fitter working inside boiler combustion chambers. A source of hexavalent chromate is traced to the action of the heat and alkaline fuel ash on trivalent chrome ore in parts of the refractory lining. Removal of the patient from this contact has resulted in almost complete clearing of his dermatitis, without any relapse, during a 9-month follow-up period.

Toxic woods.

Eighty-three cases of dermatitis caused by wood or sawdust have been seen at St John's Hospital for Dieases of the Skin, London, in the last 20 years. The clinical details and results of patch tests are reported. The literature on dermatitis, mucosal irritation, asthma and other toxic effects of woods of some 300 botanical species is reviewed at length, with an index of scientific, trade and vernacular names, chemical formulae of the known sensitizing substances, and a table of the 28 toxic woods most often encountered. Pathogenesis, diagnosis and prophylaxis are discussed.
