Advanced stages of mycobacterial diseases such as leprosy and tuberculosis are characterized by a loss of T-cell function. The basis of this T-cell dysfunction is not well understood. The present report demonstrates major alterations in the expression of signal transduction molecules in T cells of leprosy patients. These alterations were most frequently… (More)
BACKGROUND Previous reports demonstrated the usefulness of in vitro cultured epidermis for repigmenting vitiligo. OBJECTIVE Our purpose was to determine the potential of in vitro cultured epidermal sheets to treat extensive areas of intractable vitiligo. METHODS In nine patients with long-standing, stable, and refractory vitiligo, autologous epidermis… (More)
A new method for repigmenting vitiligo by transplantation of in vitro-cultured epidermis bearing melanocytes is described. The artificially grown epidermis was implanted after vitiliginous skin was denuded with liquid nitrogen. Satisfactory repigmentation was attained. This technique offers a new approach for treating refractory vitiligo.
BACKGROUND Among all the topical immunomodulators, vitiligo's mainstay therapy includes topical corticosteroids. Many other non-immune theories have also been suggested for vitiligo's pathogenesis, but the role of oxidative stress has gained more importance in recent years. OBJECTIVE To compare the effect of topical 0.05% betamethasone vs.… (More)
Autologous minigrafting has been reported as an effective method for repigmenting diverse types of stable leukoderma. A group of 22 patients with localized vitiligo, 17 segmental and five focal, who are under treatment with this method, are described. Thirteen patients attained a 90% to 100% repigmentation, two others achieved a partial improvement, and… (More)
BACKGROUND Refractory and stable defects of vitiligo and piebaldism may be unresponsive to medical therapy. Melanocyte transplantation can restore the normal pigmentation in some selected patients. OBJECTIVES To evaluate the efficacy of additional mini-grafting with 1.0-1.2-mm punch grafts to complete the restoration of achromic defects when performing… (More)
Segmental vitiligo (SV) shows distinct clinical, physiologic, and therapeutic characteristics as opposed to those seen in generalized vitiligo (GV). Three patients affected with SV, a relatively unresponsive dermatosis, were successfully repigmented by autologous minigrafting. The achieved results demonstrate a new therapeutic approach for SV.
Thirteen patients with vitiligo (1 segmental, 4 focal, 8 generalized) aged 7 to 38, most of them female children, developed numerous punctate hypopigmented and achromic spots. The spots measured 0.5 to 1.5 mm and were located primarily on the sun-exposed areas of the extremities; they appeared following treatment with PUVASOL. Two of these patients… (More)
