The recent release of an easy-to-apply patch test system has made standard patch testing more practical for the busy office practitioner. This is an important advance since contact dermatitis is being increasingly recognized as a major cause of eczema recalcitrant to treatment.

Nicotine is a toxic substance which is readily available from a wide variety of sources. Due to the universal availability of nicotine, the primary care physician may encounter accidental or deliberate poisoning in a variety of clinical settings and should be familiar with diagnosis and management of nicotine toxicity.

Three other cases illustrating the effects and clinical management of nicotine poisoning are also reviewed. The etiology, diagnosis and management of nicotine overdose are discussed.
