All the late lesions showed extensive fibrosis especially in the perifollicular areas. Scattered lymphocytes, histiocytes and neutrophils were present within the fibrotic areas. A possible explanation of the pathogenesis is discussed.
Until recently, various therapies for localized scleroderma have been used with limited success. Recently, phototherapy, with or without psoralen, was proposed as a successful treatment modality. The aim of this study was to evaluate the effect of broad-band low-dose ultraviolet A (UVA) phototherapy in patients with localized scleroderma, using a new method for evaluation. Twelve patients complaining of morphea were exposed to UVA irradiation at a dose of 20 J/cm2 3 times per week for 20 sessions. Selected covered plaques served as internal controls. The efficacy of therapy was judged clinically by sequential inspection and palpation. In biopsy specimens from exposed and covered plaques stained with hematoxylin and eosin (H & E) and Masson trichrome stains, the concentration of collagen per dermal surface area was measured with the use of a computerized image analyzer. All patients reported remarkable softening of skin lesions, confirmed by sequential palpatory assessment. A significant reduction in the mean concentration of collagen per surface area was detected in the plaques exposed to UVA (the P value being 0.007, P<0.01), whereas in the covered plaques the difference was not statistically significant (the P value being 0.10, P>0.05). The conclusion is that low-dose broad-band UVA phototherapy is a very effective and safe treatment modality for localized scleroderma.
Background: Alopecia areata (AA) is an immune-mediated disease that targets anagen hair follicles. Despite various therapeutic options, there is no cure for AA. Prostaglandin analogues have been recognized as being capable of inducing hypertrichosis. Objective: To compare the efficacy and safety of bimatoprost to those of corticosteroid in the treatment of scalp AA. Methods: Thirty adult patients with patchy AA (S1) were included. Two AA patches were randomly assigned to treatment either by mometasone furoate 0.1% cream once daily (area A) or bimatoprost 0.03% solution twice daily (area B) for 3 months. Patients were assessed using the Severity of Alopecia Tool (SALT) scoring system for hair re-growth. Results: All responding AA patches showed significant reduction in their SALT score after therapy. Area B demonstrated significantly better results regarding rapidity of response in weeks, percentage of hair re-growth and side effects compared to area A. Conclusion: Bimatoprost solution represents a therapeutic option for scalp AA.
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.
