Mycosis fungoides (MF) is the most common cutaneous T cell lymphoma (CTCL). Generally it affects patients over 50 years of age being rare in children. Its clinical presentation is very heterogeneous with several clinicopathological variants. The treatment of MF depends on its stage, variant and the characteristics of the patient.

BACKGROUND/PURPOSE: Skin commensal bacteria have been described to help orchestrate skin homeostasis, signaling through innate immunity pathways. This study for the first time aimed at studying the relationship between skin commensals and melanocytes after UVB exposure. METHODS: An in vitro UVB radiation model with normal human epidermal melanocytes (NHMs) and skin commensal bacteria supernatant from S. epidermidis and P. acnes was established. Melanocytes DNA damage, cyclobutane pyrimidine dimers (CPD), and cellular proliferation marker Ki-67 were measured by ELISA and immunofluorescence staining...

Lok Chin Wong, Adawiyah Jamil, Norazirah Md Nor
BACKGROUND: Ethnicity, skin phototype and colour influenced minimal erythema dose (MED). Sun exposure has been postulated to increase MED. We determined immediate pigment darkening dose to UVA (IPDDA), MED and minimal melanogenic dose (MMD) for UVB and UVA, and investigated factors affecting these doses. METHODS: Skin phototype was determined using Fitzpatrick phototype quiz, DSMII ColorMeter measured skin colours, sun exposure quantified using an index (SEI) and phototest performed with MEDlight-Multitester...

BACKGROUND: Chronic actinic dermatitis (CAD) develops in seasons where there is high sun exposure, such as summer, and can persistent throughout the year in severely affected cases. The authors noted that CAD prevalence increased in relation to climate changes and air pollutants. METHODS: We retrospectively analyzed 294 patients with newly diagnosed CAD between December 2000 and November 2016. We investigated the annual trend of sun hours, humidity, and ground-level ozone and respirable particles (PM10) in Pusan, Korea; correlations between climate change and/or air pollution and the incidence of patient with CAD were analyzed...

BACKGROUND/PURPOSE: Sun sensitivity, a confounder between sun exposure and sun protection, is often overlooked. We examined how sun exposure and sun protection behaviors among indoor workers varied by sun sensitivity. METHODS: Sun exposure and sun protection diaries over a 45-day period from Midwestern United States indoor workers were examined. We categorized sun sensitivity (fair and non-fair complexion) using tanning inability and sunburn tendency. Total exposure (sunrise to sunset) and peak exposure (10 am and 4 pm) lasting at least 60 minutes were examined...

BACKGROUND/PURPOSE: Skin phototype questionnaires usually ask similar questions, but they differ in how the answers can be given. There is either one combined answer, which includes both tendency to burn and ability to tan, or 2 separate answers about burn and tan, respectively. We tested the reproducibility of different questionnaires and their relation to objectively measured skin phototype. METHOD: A total of 149 participants completed 3 skin phototype questionnaires distributed twice with median 3 months interval: (i) a Fitzpatrick questionnaire (FST-q) with combined answers about tendency to burn and ability to tan, (ii) a detailed questionnaire (Detail-q) with separate answers to 2 detailed questions about burn and tan and (iii) a short questionnaire (Short-q) with separate answers to 2 simplified questions about burn and tan...

REVIEW
Nahla Shihab, Henry W Lim
The increased use of ultraviolet (UV) nail lamps in recent years has generated safety concerns of this device. A UV nail lamp is a source of artificial UVA radiation, often used to dry, harden, and cure the nails at home and in the salon. UVA radiation is known to be mutagenic and can cause damage to the DNA, resulting in cutaneous malignancy. Currently, there are only a few studies that have evaluated UV nail lamp irradiation and its potential carcinogenic risk. We review the literature on UV nail lamps, its safety, effect on nails and hands, and the potential role in increasing the risk of cutaneous malignancy...

BACKGROUND: Ultraviolet (UV) B irradiation has been shown to improve atopic dermatitis (AD). However, the relationship between UVB eye irradiation and AD is not known. This issue was addressed using a mouse model of AD. METHODS: The eyes of NC/Nga mice were irradiated with UVB at a dose of 1.0 kJ/m2 using a 20SE sunlamp for the duration of the experimental period. RESULTS: AD symptoms deteriorated upon UVB eye irradiation. The levels of adrenocorticotropic hormone (ACTH) in the plasma and nucleotide-binding domain and leucine-rich-containing family, pyrin domain-containing (NLRP)3 and neutrophil markers in the skin were increased in UVB-irradiated mice...

BACKGROUND: Solar urticaria (SU) is a rare photodermatosis. Treatment is challenging, and outcomes are often disappointing. Omalizumab is an anti-IgE, currently approved for treatment of chronic spontaneous urticaria. We sought to evaluate therapy with omalizumab in refractory SU and describe predictive factors for response. MATERIALS/METHODS: Patients with refractory SU under treatment with omalizumab were included in this study. Clinical outcome was evaluated using the Urticaria Activity Score 7 (UAS7), Dermatology Life Quality Index (DLQI) and Pruritus Visual Analogue Scale (VAS)...
