Ultraviolet radiation, both UVA and UVB, influences the composition of the skin microbiome.

Background: Studies have begun to investigate the complex relationship between host and microorganisms in non-infectious pathologies such as acne, atopic dermatitis and psoriasis. Though the skin is exposed to environmental stressors such as ultraviolet radiation (UVR), no studies exist examining the effects of both UVA and UVB on the skin microbiome.

Objective: To test the effect of UVA and UVB on human skin microbiome.

The impact of oral Polypodium leucotomos extract on ultraviolet B response: A human clinical study.

Background: There is a rationale for adding systemic photoprotective agents to the current photoprotection regimen.

Objective: This study was designed to objectively evaluate the molecular and photobiologic effects of oral administration of Polypodium leucotomos extract (PLE).

Methods: In all, 22 subjects with Fitzpatrick skin phototype I to III were enrolled.

Comorbid autoimmune diseases in patients with vitiligo: A cross-sectional study.

Background: Few large-scale studies have quantified the burden of comorbid autoimmune diseases in patients with vitiligo.

Objective: We sought to determine the prevalence of comorbid autoimmune diseases in patients with vitiligo.

Methods: We conducted a manual chart review on a cohort of 1873 patients with vitiligo seen between January 2002 and October 2012 at the Henry Ford Health System in Detroit, MI.

Uncommon responses of segmental vitiligo to melanocyte-keratinocyte transplantation procedure.

Background: Patients with segmental vitiligo (SV), unlike those with nonsegmental vitiligo (NSV), have a more predictable course and are more responsive to surgery.

Objective: To report 10 patients with SV treated with the melanocyte-keratinocyte transplantation procedure (MKTP), who responded with unusual responses not previously reported in the literature.

Methods: This is a retrospective, observational study that reports 10 patients with SV who underwent the MKTP between May 2003 and May 2012.

Polymorphous light eruption presenting as pinhead papular eruption on the face.

Polymorphic light eruption (PMLE) is the most common of the immunologically mediated photodermatoses. Onset is typically within the first three decades of life and affects females two to three times more than males. It occurs 30 minutes to 1-3 days after sun exposure and usually resolves in 7 to 10 days.
