Treating advanced or recurrent melanoma remains a challenge. Cancer cells can evade the immune system by blocking T-cell activation via overexpression of the inhibitory receptor programmed death 1 (PD-1) ligands. The PD-1 inhibitor nivolumab blocks the inhibitory signal in T cells, thus overcoming the immune resistance of cancer cells. Nivolumab has demonstrated promising anti-cancer activity in various cancers. We conducted a single-arm, open-label, multicenter, phase II study to investigate the efficacy and safety of nivolumab in previously untreated Japanese patients with advanced melanoma...

Vernonia anthelmintica (L.) Willd has been traditionally used in the treatment of vitiligo in Uyghur medicine. This study used butin, the main component of V. anthelmintica, to study the influence on hydroquinone-induced vitiligo in mice. The animals were randomly divided into six groups: control, model, 8-methoxypsoralen (8-MOP, 4.25 mg/kg), and butin (0.425, 4.25, and 42.5 mg/kg) groups. The number of melanin-containing hair follicles, basal layer melanocytes, melanin-containing epidermal cells, the expression of tyrosinase (TYR) and tyrosinase-related protein-1 (TRP-1), the malondialdehyde (MDA), and cholinesterase (CHE) activity in serum were measured...

BACKGROUND/OBJECTIVES: Phototherapy is a commonly used treatment for vitiligo that has demonstrated safety and efficacy. High-intensity targeted ultraviolet B (UVB) light (304-312 nm) delivered using a phototherapy device is a useful therapeutic option because it can induce repigmentation in a short time without global exposure to radiation, but information regarding this device in children is limited. METHODS: We performed a retrospective analysis of 95 patches of vitiligo in 27 children treated using a targeted phototherapy device...

The pathogenesis of vitiligo involves interplay between intrinsic and extrinsic melanocyte defects, innate immune inflammation, and T-cell-mediated melanocyte destruction. The goal of treatment is to not only halt disease progression but also promote repigmentation through melanocyte regeneration, proliferation, and migration. Treatment strategies that address all aspects of disease pathogenesis and repigmentation are likely to have greatest efficacy, a strategy that may require combination therapies. Current treatments generally involve nontargeted suppression of autoimmunity, whereas emerging treatments are likely to use a more targeted approach based on in-depth understanding of disease pathogenesis, which may provide higher efficacy with a good safety profile...

Vitiligo is an autoimmune disorder that involves the interplay between oxidative stress and the immune system. Preliminary observations suggest that the presence of gluten in the diet may play a role in vitiligo development in some patients, but to date vitiligo-specific diets have not been studied. The role of oral supplements, including vitamins, minerals, and botanicals, is increasingly being investigated as adjuncts to conventional medical treatment due to their antioxidant and immunomodulatory activity...

Childhood vitiligo differs from adult-onset vitiligo for several features including increased incidence of the segmental variant, higher prevalence of halo nevi, and more common family history for autoimmune diseases and atopic diathesis. The major differential diagnoses are the postinflammatory hypomelanoses for nonsegmental vitiligo and nevus depigmentosus for segmental vitiligo. From a therapeutic standpoint, early awareness of the diagnosis seems to correlate with a good treatment outcome in this age group...

Surgical management is a safe and effective treatment modality for select patients with vitiligo. Many techniques of vitiligo surgery exist, each with unique advantages and disadvantages. Preoperative screening for appropriate candidates, selection of surgical technique, and postoperative management are all key elements in enabling patients to achieve maximal repigmentation.

Vitiligo is a disease characterized by disappearance of melanocytes from the skin. It can negatively influence the physical appearance of affected individuals, and may profoundly affect a person's psychosocial function and quality of life. Therefore, vitiligo should not be considered as merely a condition that affects a patient's appearance, but needs to be actively treated in patients who seek medical help. Phototherapy has been used as the main treatment modality for patients with vitiligo. Different forms of phototherapy for vitiligo include broadband UVB, narrowband UVB, excimer light and excimer laser, and psoralen plus UVA...

Medical treatments alone, or in combination with phototherapy, are key approaches for treating nonsegmental vitiligo and, to a lesser extent, segmental vitiligo. The treatments are useful for halting disease progression and have been proven effective for inducing repigmentation and decreasing risk of relapses. Although the treatments have side effects and limitations, vitiligo often induces a marked decrease in quality of life and in most cases the risk:benefit ratio is in favor of an active approach. Systemic and topical agents targeting the pathways involved in loss of melanocytes and in differentiation of melanocyte stem cells should provide more effective approaches in the near future...

Vitiligo has a variety of presentations, including focal, acrofacial, segmental, and generalized forms. Thorough knowledge of these presentations is important to make the correct diagnosis. Signs of activity are important to recognize so that treatment is optimized. Clinical findings of confettilike depigmentation, trichrome and inflammatory vitiligo, and the Koebner phenomenon should alert the clinician that a patient's disease is likely to worsen. These patients may require systemic treatment to stabilize their disease...

Discolorations of the skin, such as vitiligo, were recognized thousands of years ago. White spots caused by vitiligo and other disorders have caused significant social opprobrium to those disfigured by these pigmentary disorders, throughout history and still in the present day. Treatments have been desperately sought with only partial success. Recent advances suggest that vitiligo and other pigmentary disorders might soon be curable.

Autologous skin cell suspensions have been used for wound healing in patients with burns and against normal pigmentation in vitiligo. To separate cells and the extracellular matrix from skin tissue, most researchers use enzymatic digestion. Therefore, this process is difficult to perform during a routine surgical procedure. We aimed to prepare a suspension of noncultured autologous skin cells (NCSCs) using a tissue homogenizer as a new method instead of harsh biochemical reagents. The potential clinical applicability of NCSCs was analyzed using a nude-rat model of burn healing...

Stem cells play an important role in medical science, and scientists are investing large sums in order to perform sophisticated studies designed to establish potential clinical applications of stem cells. Growing experience has enabled researchers to determine the precise nature of stem cell division. Although the properties of this particular population of cells have been known and used for some time, mainly with regards to bone marrow-derived mesenchymal stem cell transplantation, we now face a significant challenge in implementing the practical use of skin-derived precursors, making it possible to avoid the necessity for patients to undergo invasive procedures in order to obtain stem cells from bone marrow...
