BACKGROUND/OBJECTIVES: A combination of narrowband ultraviolet B (NBUVB) phototherapy plus topical tacrolimus has been used in adult vitiligo but has not yet been explored in children. We therefore sought to highlight the efficacy of this synergistic combination in childhood vitiligo. The objective was to study the clinical efficacy and safety of a combination of NBUVB with topical tacrolimus ointment 0.03% in childhood vitiligo. METHOD: In this open-label study, 20 children, 4 to 14 years of age, with symmetrical vitiligo lesions were enrolled for 24 weeks...

BACKGROUND: The treatment of vitiligo is still one of the most difficult dermatological challenges, although there are many therapeutic options. Narrow band ultraviolet B (NB-UVB) phototherapy is considered to be a very important modality for generalized vitiligo. OBJECTIVE: The aim of this study was to explore whether a combination of NB-UVB and topical agents would be superior to NB-UVB alone for treating vitiligo. METHODS: We searched the electronic databases such as PUBMED, EMBASE, Cochrane Library and Web of Science...

Vitiligo is the most common depigmentation disorder, affecting around 1% of population worldwide. There is no cure, and no firm clinical recommendations can be made for the treatment of vitiligo. A European guideline suggests early treatment of small lesions of recent onset and childhood vitiligo with combination of phototherapy and topical agents. Suitable facilities and equipment, such as hand-held portable phototherapy devices, are needed, if this new guideline is to be implemented. Hand-held units are suitable for small lesions, making phototherapy available for patients with limited and/or early vitiligo...

Phototherapy has been the mainstay of vitiligo therapy for several decades. A variety of wavelengths and modalities are available, but narrowband ultraviolet B remains the safest and most commonly used treatment. Acting on multiple steps in vitiligo pathogenesis, narrowband ultraviolet B is one of the few therapies that can effectively induce stabilization and stimulate repigmentation. Achievement of optimal results involves using a combination of appropriate treatment protocols, careful patient selection, and patient education to set expectations...

Vitiligo, an acquired depigmentation disorder, manifests as white macules on the skin and can cause significant psychological stress and stigmatization. Recent advances have shed light on key components that drive disease onset and progression as well as therapeutic approaches. Vitiligo can be triggered by stress to the melanin pigment-producing cells of the skin, the melanocytes. The triggers, which range from sunburn to mechanical trauma and chemical exposures, ultimately cause an autoimmune response that targets melanocytes, driving progressive skin depigmentation...

BACKGROUND/PURPOSE: Vitiligo is the most commonly acquired depigmentation disorder of the skin and is characterized by the destruction of melanocytes. Ultraviolet phototherapy with narrow band (UVB-NB) induces proliferation, differentiation, maturation, and migration of melanocytes. The clinical repigmentation is featured by follicular, marginal, and diffuse patterns. The aim of this study was to observe the process involved in the melanocyte migration and proliferation among these patterns and the unresponsive lesions following UVB-NB phototherapy...

Vitiligo is an acquired, idiopathic depigmentary disease resisting satisfactory repigmentation despite multimodal therapy. Based on the concept of activation of the existing undifferentiated stem cells in the outer root sheet of the hair follicles, follicular unit extraction (FUE) transplant is an interesting advancement in the field of minimally invasive surgery for vitiligo. We herein present three cases of vitiligo whose residual recalcitrant foci as well as poliosis - refractory to therapy including with previous nonculture melanocyte-keratinocyte transplant - repigmented satisfactorily after FUE transplant...

CONTEXT: Vitiligo surgeries have come a long way from tissue grafts to cultured and non cultured cell transplantation. Extracted hair follicle outer root sheath cell transplantation (EHF ORS) suspension is more enriched with melanocyte. In a hair bulb, there is one melanocyte for every five keratinocytes which is much higher than the epidermal melanin unit. AIMS: To analyse the effectiveness of cultured EHF ORS and to perform objective evaluation based on clinical improvement & photographic evidence...

BACKGROUND: Fractional CO2 laser and autologous hair transplantation are independently effective in the treatment of refractory and stable vitiligo. OBJECTIVE: The authors' purpose was to evaluate the therapeutic efficacy of fractional CO2 laser pretreatment compared with autologous hair transplantation and phototherapy alone for refractory and stable vitiligo. METHODS: A total of 20 patients with refractory and stable vitiligo were enrolled from our clinic...

BACKGROUND: In recent years, excimer light treatments have come to the fore in localized vitiligo because of their high efficacy and safety. OBJECTIVE: We aimed to evaluate the efficacy of 308-nm excimer lamp as a monotherapy and its combination with tacrolimus 0.1% or clobetasol 17-propionate 0.05% ointment in localized vitiligo. METHODS: We performed a retrospective study including a total of 82 patients who were treated with excimer lamp monotherapy (EL group) (n = 30), excimer lamp + topical tacrolimus (EL + T group) (n = 29), or excimer lamp + topical clobetasol 17-propionate (EL + CS group) (n = 23)...

BACKGROUND: Vitiligo is characterized by the loss of pigment-producing cells, melanocytes and one of the important goals of treatment is replenishing the melanocytes from existing reservoirs. Reservoir for melanocyte stem cell has been reported to be present in the skin hair follicles, but glabrous skin does not have hair follicles. Therefore, repigmentation of glabrous lesional skin is very difficult and almost rare. There is no explanation for melanocyte reservoir in the glabrous lesional skin of vitiligo patients...

BACKGROUND: The 308-nm excimer laser had been proved to be a time-efficient and potent therapeutic alternative for the management of vitiligo. Different results had been reported in different ethnic populations. OBJECTIVE: To investigate the efficacy and related contributing factors of 308-nm excimer laser in Chinese vitiligo patients. METHODS: A total of 979 Chinese patients (3478 lesions) with progressive-stage vitiligo who had received 308-nm excimer laser treatment were recruited from the vitiligo clinic of Shandong Provincial Hospital of Dermatology &Venereology from 2012 to 2014...

Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3 and 48 years were divided into three groups: group A received oral compound glycyrrhizin (OCG); group B received UVB applications twice weekly, and group C received OCG+UVB...

A 75-year-old woman diagnosed with multiple myeloma in 2007 began treatment with monthly melphalan and prednisone for a total of 9 cycles in combination with thalidomide in 2009. The patient subsequently continued on thalidomide for long-term maintenance therapy. 3 years following initiation of thalidomide, the patient mentioned to her oncologist that her hair had become darker over the years. She attributed the change to thalidomide given the temporal relationship and progressive darkening over the course of therapy...

Silvery hair is a characteristic finding of 3 rare autosomal recessive disorders: Chédiak-Higashi syndrome (CHS), Elejalde syndrome (ES), and Griscelli syndrome (GS). We report the case of a 2-month-old male infant with transient silvery hair and generalized hypopigmentation of the skin and eyes who did not have one of these classic causative disorders. The patient was delivered at 35 weeks' gestation with congenital hydrops fetalis associated with a chromosomal abnormality (46,XY,add[2],[p23]), hypothyroidism, hypoproteinemia, and hypogammaglobulinemia...

Corals routinely lose tissue due to causes ranging from predation to disease. Tissue healing and regeneration are fundamental to the normal functioning of corals, yet we know little about this process. We described the microscopic morphology of wound repair in Pocillopora damicornis. Tissue was removed by airbrushing fragments from three healthy colonies, and these were monitored daily at the gross and microscopic level for 40days. Grossly, corals healed by Day 30, but repigmentation was not evident at the end of the study (40d)...
