One hundred and twenty patients with chronic idiopathic urticaria, who entered a study at five centres (Sheffield, London, Bristol, Cardiff and Leeds) were treated with therapeutic doses of the H1 antagonist chlorpheniramine for 6 weeks. Histamine H1 non-responders (40 patients) were entered into a double-blind study and received chlorpheniramine plus cimetidine 400 mg q.d.s. (21 patients) or chlorpheniramine plus placebo (19 patients) for a further 8 weeks. The most important response measure was the change from baseline of the total symptom score: an assessment of the number and duration of new weals and degree of itching. There was a statistically significant difference between the average response in the two treatment groups in favour of chlorpheniramine plus cimetidine after 4 and 8 weeks' treatment (P less than 0.05 and P less than 0.01, respectively). No significant side-effects related to treatment were noted.
Patients described as having lamellar ichthyosis (LI) may not all have the same disorder. We studied nine patients, four of whom had erythroderma and generalized fine scaling, while the remainder had more marked scaling and hyperkeratosis without erythema. The former group is referred to as having nonbullous congenital ichthyosiform erythroderma (CIE), and the other is said to have LI. The clinical differences were paralleled by cell kinetic and histologic differences. The mean tritiated thymidine autoradiographic labeling indices were 9.36 +/- 4.05 and 19.70 +/- 5.84 for the LI and CIE groups, respectively. The histologic differences were delineated using 10-cm analogue scales and showed statistically significant differences for hyperkeratosis and parakeratosis. These data support the hypothesis that LI and CIE are separate disorders.
We describe four patients with congenital follicular hyperkeratosis, of whom three also had pseudoacanthosis nigricans and two had facial abnormalities. Skin specimens were studied by light microscopy, autoradiography, histochemistry and scanning electron microscopy, and the results were compared with those from patients with keratosis pilaris. The condition appears to constitute a distinctive form of ichthyosis in which the abnormal epidermal differentiation occurs mainly within the hair follicles.
