Hypertrophic scars and keloids are challenging to manage, particularly as sequelae of burns in children in whom the psychologic burden and skin characteristics differ substantially from adults. Prevention of hypertrophic scars and keloids after burns is currently the best strategy in their management to avoid permanent functional and aesthetical alterations. Several actions can be taken to prevent their occurrence, including parental and children education regarding handling sources of fire and flammable materials, among others. Combination of therapies is the mainstay of current burn scar management, including surgical reconstruction, pressure therapy, silicon gels and sheets, and temporary garments. Other adjuvant therapies such as topical imiquimod, tacrolimus, and retinoids, as well as intralesional corticosteroids, 5-fluorouracil, interferons, and bleomycin, have been used with relative success. Cryosurgery and lasers have also been reported as alternatives. Newer treatments aimed at molecular targets such as cytokines, growth factors, and gene therapy, currently in developing stages, are considered the future of the treatment of postburn hypertrophic scars and keloids in children.

There is no panacea in the treatment of AKs. The current best approach is the sequential treatment with a lesion-directed and a field-directed therapy. Several combinations seem to work well; they just need to be selected based on the evidence and adjusted to patient needs, preferences and dermatologist expertise.

Actinic keratosis (AK) represents the initial intraepidermal manifestation of abnormal keratinocyte proliferation with the potential of progression to squamous cell carcinoma (SCC). When in limited numbers, clinically visible AKs are treated individually with ablative and/or surgical procedures (lesion-directed treatment), while multiple and sublinical AKs are treated with field-directed therapies that use ablative, nonablating and other topically applied treatment modalities. Owing to difficulties in predicting which AK will progress to SCC, the general rule is to treat all AKs. The goals of treatment are to eliminate the AKs, minimizing their risk of progression to invasive SCC, while pursuing good cosmetic outcomes. Prevention is the most important treatment modality for AKs. Avoidance of sun and artificial sources of ultraviolet light, applying sunscreen and self-examination are among the most effective preventive measures. Chemopreventive modalities such as retinoids, 2-(Difluoromethyl)-dl-ornithine (DFMO), perillyl alcohol, T4 endonuclease V, and dl-alpha-tocopherol are described. Lesion-directed treatment modalities include cryotherapy, surgery and electrodessication with or without curettage. Field-directed treatment modalities include nonablative and ablative laser resurfacing, dermabrasion, chemical peels, topical immunomodulators (imiquimod, 5-fluorouracil and diclofenac) and photodynamic therapy. And, finally, newer and investigational treatment modalities such as ingenol mebutate, resiquimod and betulinic acid are also being discussed.

Human papillomavirus and Herpes simplex virus are the most common genital viral infections encountered in clinical practice worldwide. We reviewed the literature focusing on new and experimental treatment modalities for both conditions, based on to the evidence-based data available. The modalities evaluated include topical agents such as immune response modifiers (imiquimod, resiquimod, and interferon), antivirals (penciclovir, cidofovir, and foscarnet), sinecatechins, microbiocidals (SPL7013 gel, and PRO 2000 gel), along with experimental (oligodeoxynucleotides), immunoprophylactic, and immunotherapeutic vaccines.
