Wound healing, scarring and management.

Understanding wound healing is imperative for the dermatological physician to optimize surgical outcomes. Poor healing may result in negative functional, cosmetic and psychological sequelae. This review briefly outlines the physiology of wound healing, with a view to improving the management of wounds and scars, and minimizing the long-term scarring complications.

Orange palpebral spots: A case presentation.

Orange palpebral spots are described as bilateral, ovoid, poorly defined orange-yellow macules on the superior eyelid and are predominantly reported in Caucasian populations. Previous reports have found correlations with melatonin incontinence secondary to trauma, lipofuscin accumulation in patients with superficial fatty tissue and palpebral thinness, and vitamin E, carotenoid and beta-cryptoxanthin levels. We present, to our knowledge, the first case of orange palpebral spots reported in the United Kingdom, in a patient with a background of atopy, significant sun exposure, bilateral cataracts and retinal detachment.

HLA Immunogenotype Determines Persistent Human Papillomavirus Virus Infection in HIV-Infected Patients Receiving Antiretroviral Treatment.

A proportion of human immunodeficiency virus (HIV)-infected patients develop persistent, stigmatizing human papillomavirus (HPV)-related cutaneous and genital warts and anogenital (pre)cancer. This is the first study to investigate immunogenetic variations that might account for HPV susceptibility and the largest to date to categorize the HPV types associated with cutaneous warts in HIV-positive patients. The HLA class I and II allele distribution was analyzed in 49 antiretroviral (ART)-treated HIV-positive patients with persistent warts, 42 noninfected controls, and 46 HIV-positive controls.

Ex-vivo recognition of late-lytic CD8 epitopes specific for Kaposi's sarcoma-associated herpesvirus (KSHV) by HIV/KSHV-coinfected individuals.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi's sarcoma (KS), the most common cancer in individuals with untreated HIV/AIDS. Host control of KSHV infection and KS oncogenesis by CD8 T cells remains underexplored. Although KSHV CD8 epitopes have been identified, the responses they elicit are weak and little is known about their relative importance.

Evaluation of a novel broad-spectrum PCR-multiplex genotyping assay for identification of cutaneous wart-associated human papillomavirus types.

A large number of human papillomavirus (HPV) types, distributed over five papillomavirus genera, are detectable in the skin. HPV types belonging to the alpha, gamma, and mu genera have been detected in cutaneous warts. A state-of-the-art HPV genotyping assay for these cutaneous wart-associated HPV types does not exist although warts constitute a highly prevalent skin condition, especially in children (33%) and organ transplant recipients (45%).
