Topically applied niacinamide in isoniazid-induced pellagra.

A patient with tuberculous meningitis developed a pellagra-like skin eruption after treatment with isoniazid. Administration of the drug was continued, and a topical preparation of niacinamide (nico-tinamide) was applied to one half of the face and the back of one hand. The areas treated responded rapidly, and subsequently all affected areas of the patient were treated, with almost complete resolution of the rash. At the same time, there was noticeable improvement in the patient's depression and apathy. We suggest that all of these changes could be due to percutaneous absorption of niacinamide.

Cutaneous and ocular reactions to practolol.

A total of 21 patients suffering from drug-induced rashes from practolol have been seen over the past two years.

Persistent ocular damage was a feature in three cases.
