The WHIM syndrome is a rare immunodeficiency disorder characterized by warts, hypogammaglobulinemia, infections, and myelokathexis. Dominant heterozygous mutations of the gene encoding CXCR4, a G-protein-coupled receptor with a unique ligand, CXCL12, have been associated with this pathology. We studied patients belonging to 3 different pedigrees. Two(More)
BACKGROUND Kaposi's sarcoma (KS), a virus-associated neoplasm, can be treated locally or systemically with interferon alfa. Therefore, imiquimod, an immune response modifier able to induce interferon-alpha secretion in situ, could prove a good local treatment for KS skin lesions. OBJECTIVE We sought to determine the efficacy and safety of imiquimod 5%(More)
Melanoma is a major malignancy in younger individuals that accounts for 8% of all neoplasias associated with gestation. During pregnancy, a small number of fetal cells enter the maternal circulation. These cells persist and then migrate to various maternal tissues where they may engraft and differentiate, particularly if there is organ damage, adopting the(More)
BACKGROUND Daylight photodynamic therapy (DL-PDT) of actinic keratosis (AK) has shown preliminary efficacy and safety results comparable to conventional photodynamic therapy (c-PDT), using methyl aminolevulinate (MAL) cream. OBJECTIVES To demonstrate the efficacy and safety of DL-PDT vs. c-PDT in treating mild facial/scalp AK. MATERIALS AND METHODS This(More)

It is unclear how the immune response controls human herpesvirus 8 (HHV8; also known as Kaposi sarcoma-associated herpesvirus [KSHV]) replication and thereby prevents Kaposi sarcoma (KS). We compared CD8 T-cell responses to HHV8 latent (K12) and lytic (glycoprotein B, ORF6, ORF61, and ORF65) antigens in patients who spontaneously controlled the infection(More)
The occuloalbinism 2 (OCA2) gene, localized at 15q11, encodes a melanosomal transmembrane protein that is involved in the most common form of human occulo-cutaneous albinism, a human genetic disorder characterized by fair pigmentation and susceptibility to skin cancer. We wondered whether allele variations at this locus could influence susceptibility to(More)
BACKGROUND Hidradenitis suppurativa (HS) is a chronic and debilitating disorder. Despite its significant prevalence, few reports of therapeutic studies are available. Recent case studies have reported the efficacy of antitumor necrosis factor monoclonal antibodies in treating the condition. In the study presented here, we assessed the safety and efficacy of(More)
BACKGROUND/OBJECTIVES Solar (actinic) keratosis (AK) is an emergent concern worldwide and is associated with an increased risk of development of non-melanoma skin cancer, especially squamous cell carcinoma. Daylight-mediated photodynamic therapy (DL-PDT) using methyl aminolaevulinate cream has proved to be an effective, nearly painless, and more convenient(More)
In this study, we assessed the role of melanocortin 1 receptor (MC1R) variants and of two patched (PTCH) polymorphisms (c.3944C>T (P1315L), insertion 18 bp IVS1-83) as risk factors for basal cell carcinoma (BCC) in the French population. The population investigated comprised 126 BCC patients who were enrolled on the basis of specific criteria (multiple(More)
