ABSTRACT

BACKGROUND: To determine the efficacy and safety of the 585-nm pulsed dye laser (PDL) in the treatment of recalcitrant warts in children. METHODS AND MATERIAL: Retrospective survey of the medical records of children with recalcitrant warts who were treated with PDL between March 1995 through January 1999 at the Children's Memorial Hospital outpatient subspecialty center, Chicago, Illinois. RESULTS: Sixty-one children with recalcitrant warts were treated with PDL; 75% of them had total clearance of warts after an average of 3.1 treatment sessions. Overall success rates were 100% for both perineal and perianal and face-only warts, 93% for hands, 69% for plantar warts, 67% when both face and extremities were involved, and 60% when multiple extremities were involved. Pain and other side effects were minimal. Mild scarring occurred in 2% of patients; 75% of patients remained free of warts after a follow-up period of 24 months or longer. CONCLUSION: PDL therapy is an effective, safe alternative therapy for treatment of recalcitrant warts in children, with few side effects and a low long-term recurrence rate.

ABSTRACT

The field of genetics in dermatology has progressed at an astonishing rate. Most of the known single gene disorders have at least been mapped to a particular chromosomal region and the causative genes have been identified and studied in many of them. However, most research work in genetics relating to genodermatoses has been confined to the western population. Very few reports, if any, have been published from Indian studies. A first step may be to develop a registry to link most of these cases providing a full description of the clinical phenotype. We would next need to attempt genetic analysis of these conditions thereby detecting any novel mutations in known and unknown genes different from the western population. This would help in designing indigenous assays appropriate to the Indian population. The review describes various techniques used in a molecular biology/ genetics laboratory with special focus on polymerase chain reaction (PCR), gene sequencing, genotyping and DNA micro arrays. Gene identification strategies have also been described with appropriate examples in dermatology.
