Systemic scleroderma-also known as systemic sclerosis (SSc)-is a chronic systemic connective tissue disease characterized by collagen deposition in cutaneous and internal organs, leading to skin sclerosis and multiple organ fibrosis. The pathogenesis is complex and remains poorly understood. Treatment is based on organ involvement and requires a multidisciplinary approach. Skin sclerosis can cause disability, leading to decreasing quality of life. Various systemic anti-fibrotic therapies have been used; however, most have unsatisfactory results...

Sonja Radakovic, Adrian Tanew
BACKGROUND: Actinic cheilitis (AC) is a common disease caused by chronic ultraviolet exposure. OBJECTIVE: Alacare is a self-adhesive, skin coloured 5-aminolaevulinic acid (ALA) patch that has been developed for the treatment of mild to moderate actinic keratosis (AK). Considering the good results in the treatment of AK, the standardized delivery of ALA and the simple application Alacare patch PDT appears as an interesting treatment option for AC. METHODS: We retrospectively assessed the efficacy, tolerability and cosmetic outcome of Alacare patch PDT in eleven patients with AC...

REVIEW
Ashley Sample, Yu-Ying He
Melanoma is the deadliest form of skin cancer and its incidence is rising, creating a costly and significant clinical problem. Exposure to ultraviolet (UV) radiation, namely UVA (315-400 nm) and UVB (280-315 nm), is a major risk factor for melanoma development. Cumulative UV radiation exposure from sunlight or tanning beds contributes to UV-induced DNA damage, oxidative stress, and inflammation in the skin. A number of factors, including hair color, skin type, genetic background, location, and history of tanning, determine the skin's response to UV radiation...

REVIEW
Rashi Minocha, Diona L Damian, Gary M Halliday
Ultraviolet radiation (UVR) causes DNA damage in melanocytes by producing photolesions such as cyclobutane pyrimidine dimers and 8-oxo-7-hydrodeoxyguanosine. The production of reactive oxygen species by UVR also induces inflammatory cytokines that, together with the inherent immunosuppressive properties of UVR, propagate carcinogenesis. Nicotinamide (Vitamin B3 ) enhances DNA repair, modulates the inflammatory environment produced by UVR and reduces UV-induced immunosuppression. As nicotinamide reduces the incidence of actinic keratoses and non-melanoma skin cancers in high-risk individuals, and enhances repair of DNA damage in melanocytes, it is a promising agent for the chemoprevention of melanoma in high-risk populations...

Narrowband ultraviolet B (NB-UVB) phototherapy is an effective treatment for vitiligo, resulting in up to 75% repigmentation in 9 months, however, compliance is often poor due to the economic burden and inconvenience associated with this form of therapy. Home phototherapy has been shown to be an effective treatment for a variety of skin conditions, including vitiligo. Despite this evidence, home phototherapy for vitiligo is considered experimental and investigational by health insurance providers. This article is protected by copyright...

Vitiligo is a disorder characterized by the development of depigmented macules and patches. Narrowband ultraviolet B phototherapy is a standard of care treatment and is used both as monotherapy and in combination with other treatment modalities to induce repigmentation. Although phototherapy is safe and effective, its use is limited due to the significant time commitment required and associated costs. Home phototherapy is a safe and effective alternative to make phototherapy more accessible to patients. However, it is often underutilized due to lack of physician experience and comfort as well as misconceptions regarding its safety and efficacy...

BACKGROUND: Until now, photoprotection of human skin has involved the development of sunscreens effective in the ultraviolet (UV) domain. During the last ten years, several studies have shown that besides the well-known damaging effects of UV, visible (400-700 nm) and even infrared light (> 700 nm) can induce damage which contributes to photoaging. Furthermore, many photodermatoses are also known to be triggered by visible light (VL). OBJECTIVE/METHOD: An in vivo method is proposed to assess the protective efficacy of sunscreens in the VL domain...

Aquagenic pruritus (AP) is a rare skin disease of unknown aetiology characterized by the abrupt onset of pruritus without visible cutaneous lesions after contact with water or humidity. AP can have a severe impact on the patient's quality of life. Although AP is mostly idiopathic, it can be associated with polycythemia vera, other hematologic disorders and medications (1). Treatment is challenging and often disappointing, and may consist in topical agents such as capsaicin 0.025-1.0%, alkaline baths and glycerol trinitrate 2%...

Hydroa vacciniforme-like lymphoproliferative disease (HVLL) was first described as the coexistence of hydroa vacciniforme and malignant lymphoma in 1986. It was renamed in the 2008 World Health Organization classification system as one of the Epstein-Barr virus (EBV)-associated lymphoproliferative diseases (LPDs) of childhood. HVLL has T cell monoclonality and is considered a rare EBV(+) cutaneous T cell lymphoproliferative disease. HVLL occurs predominantly in children and young adults of Asia and Latin America,(1, 2) and are characterised by papulovesicular eruptions, facial edema, ulceration, and atrophic scars similar to hydroa vacciniforme (HV)...
