Tissue kallikrein and kininogen in human sweat glands and psoriatic skin.

The cellular localization of immunoreactive tissue kallikrein and kininogen was studied in normal and psoriatic human skin. Immunoreactivity to both enzyme and substrate was observed in secretory granules of the dark cells in the secretory fundus (acinus) of the sweat glands. Double immunostaining revealed a segmental distribution of the two antigens. Each acinar section contained either tissue kallikrein or kininogen. However, there appeared to be a junctional zone in which both were present, but in separate dark cells. Immunoreactivity for both antigens was also observed in close apposition to the luminal microvilli of the duct cells. No specific immunostaining was seen in sebaceous glands, hair follicles, keratinocytes and other cells of the secretory unit such as myoepithelial or clear cells. In psoriatic skin there were in addition many neutrophils immunoreactive for tissue kallikrein in the epidermis and psoriatic scales. Mitogenic action of kinins may account to some extent for the characteristic accelerated turnover of epidermal cells in psoriasis and locally applied kinin antagonists may prove of value in the treatment of this disease.

Oral albendazole for the treatment of cutaneous larva migrans.

Cutaneous larva migrans is becoming more common in the U.K. with the popularity of tropical countries as holiday destinations. We describe the increasing use of a new benzimidazole derivative, albendazole, which is very effective in the treatment of cutaneous larva migrans. In contrast to thiabendazole, it is virtually free from side-effects and should, we feel, become the treatment of choice for this condition.

Administration, Oral

Exfoliative dermatitis due to nifedipine.

We report the case of a 63-year-old Caucasian female, with reno-vascular hypertension, who developed a generalized skin eruption with lichenoid histological features, induced by nifedipine. A repeat challenge with nifedipine confirmed that it was the causative agent.

Dermatitis, Exfoliative

Darkening of white hair in Parkinson's disease.

We describe a patient with long-standing Parkinson's disease who noted that his white hair turned grey and darkened 8 months after the addition of carbidopa to his established levodopa (L-dopa) therapy and 4 months after the introduction of bromocriptine.

Carbidopa

Cutaneous reaction to diltiazem resulting in an exacerbation of angina.

A 77-year-old woman developed a widespread erythematous rash after treatment with the calcium antagonist, diltiazem, which resulted in an exacerbation of the angina for which the drug was originally described. Drugs which may give widespread cutaneous side-effects should be used with caution in patients with compromised cardiac function.
