Photosensitivity was assessed in 125 patients with systemic lupus erythematosus (SLE) and in 281 patients with rheumatoid arthritis (RA) as controls. Photosensitivity was reported by 87/119 (73%) patients with SLE and in 62/269 (23%) patients with RA; involving the face in 72/122 (59%) patients with SLE, then arms, chest, and neck. Patients with SLE reported that sun exposure could exacerbate v...
Pellagra is a photosensitivity syndrome characterized by three "D's": diarrhea, dermatitis, and dementia as a result of niacin deficiency. However, the molecular mechanisms of photosensitivity dermatitis, the hallmark abnormality of this syndrome, remain unclear. We prepared niacin deficient mice in order to develop a murine model of pellagra. Niacin deficiency induced photosensitivity and seve...
Photosensitivity reactions are recognized as unwanted adverse effects of an array of commonly administered topical or systemic medications, including nonsteroidal antiinflammatory agents, antifungals, and antimicrobials. When a drug induces photosensitivity, exogenous molecules in the skin absorb normally harmless doses of visible and UV light, leading to an acute inflammatory response. In phot...
An alternative technique that uses a flame-brush at high temperature to enhance UV light photosensitivity in an optical fiber is described. An extreme low-cost air aspirated propane-butane mini-torch is used, which produces a lower temperature flame than the one in the flame-brush original technique. It is shown that this change in the previous technique is also capable of improving photosensit...
Bloom’s syndrome (BS) is a rare, autosomal recessive disease characterized by short stature, erythematous skin lesions with photosensitivity, hypo- and hyperpigmentation and recurrent bacterial infections due to immune deficiency. We report a 13-year old girl with erythema and telangiectasia in butterfly distribution on face, photosensitivity, multiple café au lait spots on trunk and extremitie...
