Background: Topical therapies are the first line of treatment for patients with stable plaque psoriasis affecting a limited body surface area. Though in use for more than a decade, we could not find any reports of studies directly comparing calcipotriol and tazarotene. Aim: To evaluate the comparative efficacy and tolerability of calcipotriol and tazarotene in the treatment of stable plaque psoriasis. Methods: This was a prospective, right-left side intra-individual parallel 8-week study using calcipotriol 0.005% ointment applied twice daily (right side) versus tazarotene (left side) randomized to either 0.05% (group I) or 0.1% gel (group II) once daily in two groups, each of 10 patients. Efficacy was determined by the assessment of target psoriatic lesions under evaluation by using the severity scale (0-3) of erythema, scaling, and infiltration (ESI score). Evaluation was done at baseline (0 week), 4 weeks, and 8 weeks of treatment. At the end of 8 weeks, patients with more than 75% reduction in ESI score were considered to have marked improvement; 51% to 75%, moderate improvement; 26% to 50%, minimal improvement; and less than 25%, non-responders. Results: Seventeen patients (9 in group I, 8 in group II) completed the study. In group I, reduction in ESI score was significantly more at both 4 and 8 weeks on sides treated with calcipotriol, producing moderate-to-marked improvement (P < 0.05). In group II, improvement was comparable in lesions treated with either calcipotriol or tazarotene (0.1%) at the end of 4 and 8 weeks. Adverse effects noted were mild - in the form of burning, pruritus, and irritation - and were observed more often in the lesions treated with tazarotene as compared to those in the lesions treated with calcipotriol, but the difference was not statistically significant. However, none of the patients discontinued the therapy because of adverse events. Conclusion: Topical calcipotriol 0.005% ointment is more effective than tazarotene 0.05% gel; however, its efficacy is comparable to tazarotene 0.1% gel in the treatment of stable plaque psoriasis.

One hundred patients with warts (Verruca vulgaris of hands-33; feet-16, hands and feet 10; palmar warts-17 and plantar warts-24) were treated with salicylic acid (16.5%) and lactic acid (16.5%) in flexible collodion wart (SAL) paint. The wart paint was applied twice a week for 3 months. Good response was seen in 82.1% of warts on hands. 46.7% of palmar warts, 54.5% of warts on feet, 84.2% of plantar warts and 57.1% of warts on hands and feet. Overall success rate was 70%. Eighty percent patients completed the study. No adverse effects were observed. During 6 months post treatment follow up recurrence of warts occurred in 11.7% of patients.

Fifty men with recurrent genital herpes were treated with either acyclovir 5% cream or tromantidine 1 % ointment applied topically. Acyclovir cream was applied 5 times and tromantidine cream 4 times daily for 5 days. At least one pre-treatment episode was observed by one of the authors. Self assessment charts were provided to the patients to record prodromal symptoms and healing time. For comparison at least 3 post treatment episodes were observed and com-pared with mean healing time of 3 pre-treatment episodes. Both acyclovir cream and tromantidine ointment significantly reduced the duration of prodrome, hastened healing and so reduced mean healing time.

Twenty rive adult male patients with uncomplicated acute gonococcal urethritis were treated with a single dose of 2 gm of spectinomycin hydrochloride given intramuscularly. All the patients were cured as proved by negative smears and cultures. No side effects were observed with the drug.
