Lichen planus (LP) is infrequently seen in children and the clinical presentation is often atypical. We conducted a retrospective analysis of clinical features and treatment response in childhood LP to date. The clinical profile and treatment response data of patients younger than 14 years old with LP (entered in a predesigned pro forma study) from January 1997 to June 2011 were analyzed. The treatment was administered according to a predetermined departmental protocol and was comprised of topical steroids with or without oral dapsone or corticosteroids. Patients were evaluated for response, adverse effects, and relapse. The study population consisted of 316 children (166 boys, 150 girls), or 18.7% of the total registered patients in the LP clinic. The mean age was 10.28 years (range 2-14 years). Cutaneous lesions were seen in 96.2%. Involvement of the oral mucosa was detected in 18%, nails in 13.9%, scalp in 8.2%, and genitalia in 4.4%. Classic LP was most prevalent (53.8%), followed by eruptive (16.5%), hypertrophic (8.2%), linear (6.9%), and lichen planopilaris (6.3%). LP pigmentosus, annular, and atrophic variants were encountered infrequently. Topical corticosteroids were the most common treatment used in 69.5% of patients, 28.8% of whom had excellent response at 6 months, although 38.8% failed to follow up. Dapsone was prescribed in 20% and systemic steroids in 9.8% of patients. We report the largest series to date of LP in childhood, with a more varied clinical presentation than in previous series. The course and response to treatment were similar to those in adults.
Local and federal government agencies are often asked to investigate apparent clusters of cancer in communities or workplaces. Often these investigations cannot utilize the methods that have been developed for evaluation of disease clusters because the clusters are too small, and the populations to be studied and the periods of time to be covered are determined in an a posteriori manner. Still, government investigators are called upon to render an official opinion of the apparent clusters. Application of a theoretical approach to cluster analysis must give way to a more pragmatic
Deposition of smegma in the subpreputial region is common in young uncircumcised boys. Although the term "smegma pearls" has been used colloquially for this entity, there is an apparent lack of reference to smegma pearls and their characteristics in the extant scientific literature. We present a series of six Indian boys with smegma pearls and discuss their possible origin, course, and management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
