The role of nickel allergy in hand dermatitis and its impact on handling cupronickel currency coins. A comparative cohort study from Kuwait.

Introduction: Contact with nickel-releasing coins as a cause of hand dermatitis has been debated.

Aim: Studying a hand dermatitis risk from handling Kuwaiti cupronickel coins among nickel-allergic and nickel non-allergic subjects.

Material And Methods: One hundred hand dermatitis patients (group I: nickel-allergic) and 100 matched patients (group II: nickel non-allergic) were selected from over 500 hand dermatitis cases seen between September 2014 and September 2015.

Allergic contact dermatitis pattern in Kuwait: nickel leads the pack. In-depth analysis of nickel allergy based on the results from a large prospective patch test series report.

Introduction: Contact dermatitis is a relatively common dermatosis reported among several population groups from all around the globe. However, the data from Kuwait is unavailable. Patch tests are essential for the diagnosis of contact sensitization.

Pachyonychia Congenita (K16) with Unusual Features and Good Response to Acitretin.

Background: Pachyonychia congenita (PC) is a rare autosomal dominant disease whose main clinical features include hypertrophic onychodystrophy and palmoplantar keratoderma. The new classification is based on genetic variants with mutations in keratin KRT6A, KRT6B, KRT6C, KRT16, KRT17, and an unknown mutation. Here, we present a case of PC with unusual clinical and histological features and a favorable response to oral acitretin.

Photoprotection: clothing and glass.

Ultraviolet (UV) radiation (UVR) has well-known adverse effects on the skin and eyes. Little attention is given to physical means of photoprotection, namely glass, window films, sunglasses, and clothing. In general, all types of glass block UV-B.

Efficacy of localized phototherapy and photodynamic therapy for psoriasis: a systematic review and meta-analysis.

Localized phototherapy including topical psoralen plus ultraviolet A (PUVA) and targeted ultraviolet B (UVB), and photodynamic therapy (PDT) have been increasingly used in the treatment of localized psoriasis. Yet, there are no systematic reviews or meta-analyses that scientifically evaluated the pooled efficacy of these treatments in psoriasis. We searched Medline, Embase, and Cochrane databases during the period of January 1980 to June 2012.

Systematic review of UV-based therapy for psoriasis.

Background: UV-based therapies, which include narrow-band (NB) UVB, broad-band (BB) UVB, and psoralen and UVA (PUVA), are well known treatment options for moderate to severe plaque psoriasis. However, there are limited evidence-based reviews on their efficacy, short-term safety, and tolerability.

Aim: The aim of the study was to evaluate the efficacy, short-term safety, and tolerability of UV-based therapy in the treatment of adults with moderate to severe plaque psoriasis.

Current status of photoprotection by window glass, automobile glass, window films, and sunglasses.

Ultraviolet radiation (UVR) has known adverse effects on the skin and eyes. Practitioners are becoming more aware of the importance of outdoor photoprotection. However, little attention is directed to the exposure of the skin and eyes to UVR through the window glass or sunglasses.

Effects of ultraviolet radiation, visible light, and infrared radiation on erythema and pigmentation: a review.

The effects of ultraviolet radiation, visible light, and infrared radiation on cutaneous erythema, immediate pigment darkening, persistent pigment darkening, and delayed tanning are affected by a variety of factors. Some of these factors include the depth of cutaneous penetration of the specific wavelength, the individual skin type, and the absorption spectra of the different chromophores in the skin. UVB is an effective spectrum to induce erythema, which is followed by delayed tanning.
