Truncal Acne in Adolescents and Young Adults: Self-reported Perception.

No epidemiological information about truncal acne is available. This study assessed the self-reported impact of truncal acne in adolescents and young adults, using an internet survey in France in 1,001 adolescents and young adults with truncal acne. Participants' mean age was 18.

Novel and emerging treatment options for acne vulgaris.

The principal actors in acne are the sebaceous gland, keratinocytes of the follicle and skin microbiome/innate immunity. Current acne treatments are frequently accompanied by side effects or may cause antibacterial resistance. New formulations and emerging treatments with novel mechanisms of action and improved formulations have recently been made available or are currently under development.

The Vitiligo Impact Patient Scale (VIPs): Development and Validation of a Vitiligo Burden Assessment Tool.

Vitiligo has a major impact on health-related quality of life. Although a few vitiligo-specific quality of life instruments exist, there is no specific vitiligo burden tool. We developed and validated a specific vitiligo burden tool according to skin phototype.

Latent class analysis of a series of 717 patients with vitiligo allows the identification of two clinical subtypes.

Non-segmental vitiligo (NSV) is an enigmatic disease with various clinical courses. To empirically identify underlying subtypes of NSV, we performed latent class analysis (LCA) of 717 consecutive patients with NSV seen between 2006 and 2012 and were analyzed. Median age was 32 yrs (14-45), median age at NSV onset was 18 yrs (8-32), and median NSV duration 5 yrs (0.

Absence of modulation of CD4+CD25 regulatory T cells in CTCL patients treated with bexarotene.

Cutaneous T-cell lymphoma (CTCL) are a heterogeneous group of lymphoproliferative disorders, characterized by the infiltration of the epidermis by mature and activated malignant CD4+ T-lymphocytes. Retinoids such as retinoic acid and synthetic analogues have long been used alone or in combination with other therapies for CTCL. Bexarotene, the first synthetic highly selective RXR retinoid, was approved for the treatment of all stages of CTCL in patients refractory to at least one systemic therapy.

About the cutaneous targets of bexarotene in CTCL patients.

There are several approved therapies for cutaneous T-cell lymphoma (CTCL). The retinoids are one of the major biologic response modifiers used in CTCL, producing good response rates but few complete responses. Bexarotene has been demonstrated to act on malignant T-cells by inducing their apoptosis, but nothing is known about its role on keratinocytes and Langerhans cells.
