Background/Purpose: The pathogenesis of chronic actinic dermatitis (CAD) is more complicated than other photodermatoses. However, the relationship between the clinical severity of CAD and the offending photocontact or contact allergens or both, and the correlations of CAD immunopathogenesis with the immunoregulatory molecules involved in adaptive immunity are yet to be investigated.
Methods:We performed phototesting with broad-spectrum ultraviolet (UV) B, UVA, and visible light to establish the presence of photosensitivity in 121 patients with CAD, together with photopatch and contact patch testing. Nine patients with CAD were selected according to their clinical severity score for CAD (CSS-CAD), and triple direct immunofluorescence analysis was performed with paraffin-embedded skin biopsy samples.
Oral candidiasis, a common fungal infection in humans, is characterized by the overgrowth of Candida species in the superficial oral epithelial mucosa. The condition is associated with multiple risk factors, including impaired salivary gland function, oral mucosal damage, and long-term antibiotic or corticosteroid use. Several treatment
options are available; nystatin and amphotericin B are the most widely used local medications. Recently, fluconazole has emerged as the preferred systemic treatment. We report a case of oral candidiasis in an 83-year-old male diagnosed with bullous pemphigoid in 2017 and previously administered methylprednisolone. He developed oral
candidiasis a few months before presentation and was treated with 10 mL nystatin suspension three times daily; unfortunately, the disease was recalcitrant to this treatment and his symptoms showed no improvement over two months. We discontinued nystatin in favor of fluconazole syrup (Diflucan®) administered by rinsing, then swallowing, 5 mL syrup once daily. The lesion improved after one month of treatment. This case demonstrates the efficacy of fluconazole as a primary treatment for oral candidiasis. The act of rinsing the mouth with syrup exposes the oral
mucosa to drug, potentially producing a better treatment response than taking the syrup orally without rinsing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
