Introduction: The human papillomavirus (HPV) vaccine has been reported to lead to clinical clearance of lesions when used as an off-label treatment for recalcitrant extragenital warts. The aim of the study is to evaluate the therapeutic and adverse effects of HPV vaccine as an adjunctive therapy for treatment-resistant acral warts. Methods: Patients with persistent warts despite first and second line therapies, and subsequently receiving the quadrivalent HPV vaccine between July 2013 and June 2016 as an adjunctive treatment for recalcitrant warts at the National Skin Centre, were included. Results: Twenty-six patients with a median age of 34 years (range 8 to 77 years) were treated with the HPV vaccine. Nineteen (73.1%) patients completed 3 doses of the vaccine, of whom 5 (26%) achieved complete clearance, 8 (42%) had partial clearance and 6 (32%) did not respond to the vaccine. Among the 4 patients who received 2 doses of the vaccine, 3 (75%) had complete clearance whereas 1 (25%) had partial improvement of their warts. None of the patients reported adverse reactions. Conclusion: Our study suggests a potential adjunctive role of the HPV vaccine in the treatment of acral warts recalcitrant to conventional therapy.

Introduction: This study aimed to assess the frequency of anxiety and depression in a cohort of adult patients with atopic dermatitis (AD) in a tertiary dermatological centre, using the Hospital Anxiety and Depression Scale (HADS). We looked for any correlation between anxiety and depression with skin disease severity. Materials and Methods: Patients with AD were recruited from the National Skin Centre, Singapore, from 2008 to 2009 for a prospective cross-sectional study. The scoring atopic dermatitis (SCORAD) grade was determined and the HADS was administered via interviews. Results: A total of 100 patients (78 males, 22 females) were enrolled (92% Chinese, 4% Malays and 4% Indians). Their average age was 25.7 years. Sixty-five percent used topical steroids, 14% had previously taken oral prednisolone for the control of disease flares, and 20% were on concurrent systemic therapy. The mean SCORAD was 55.0, with 99% of patients having moderate or severe AD. The mean HADS anxiety score was 7.2 and the mean depression score was 5.0. The level of anxiety correlated well with that of depression (Spearman’s rank correlation coefficient, ρ = 0.59, P
