The brain-skin axis in vitiligo.

Vitiligo is an acquired autoimmune skin disease characterized by patchy depigmentation of the skin, often accompanied by white hair. The aetiology of vitiligo is complex and difficult to cure, and its disfiguring appearance significantly impacts patients' mental and physical health. Psychological stress is a major factor in inducing and exacerbating vitiligo, as well as affecting its treatment efficacy, though the specific mechanisms remain unclear.

Results and Follow-Up of a Sequential Q-Switched Laser Therapy for Nevus of Ota in Infants.

Background And Aim: There is a dearth of scholarly investigation pertaining to the effectiveness and safety of laser therapy for nevus of Ota manifestation in infants. The objective of this study is to examine the efficacy and safety of administering laser therapy at an early stage to treat nevus of Ota in infants.

Methods: A total of 102 infants below the age of one who had nevus of Ota were treated at the Laser Center at Hangzhou Third People's Hospital.

Generalized Vitiligo After Stem Cell Transplantation: A Case Report.

Graft versus host disease (GVHD) is a complex immune-mediated pathophysiological process, which is caused by allogenic immune reactions between donors and recipients. No matter ac-ute or chronic GVHD, skin involvement is the most common, severe skin damage can lead to permanent disfigurement, which seriously affects the long-term quality of life of patients. We herein report a patient with generalized vitiligo after allogeneic peripheral hematopoietic stem cell transplantation (allo-HSCT) for aplastic anemia.

A Typical but Rare Case of Solitary Tinea Auricularis.

Tinea auricularis is a rare superficial fungal infection, which is easily ignored in clinic due to its atypical clinical symptoms or being accompanied with tinea capitis. In this study, a case of annular erythema with scales around the ear canal orifice was reported. After fungal culture and identification, the patient was diagnosed with infection, and was cured after 3 weeks of topical use of clotrimazole cream.

The Combination of the Mini-Punch Technique and Photodynamic Therapy for the Treatment of Mandibular Keloids and Hypertrophic Scars.

Background: Mandibular keloids and hypertrophic scars can exert significant effects on the appearance of a patient. However, current treatments are not effective in all cases. Consequently, it is vital to identify a safe and effective treatment method.

Repigmentation in two patients with vitiligo on AcEGCG 0.5% cream.

Per-acetylated epigallocatechin-3-gallate (AcEGCG), a fully acetylated derivative of EGCG, a more potent agent for protection of melanocytes from oxidative damage. We present two patients with vitiligo treated with AcEGCG 0.5% cream, who demonstrated skin repigmentation and control of depigmentation progression.

Tinea of vellus hair: shining under the Wood's lamp.

We herein reported a simple and cheap method to diagnose the tinea of vellus hair, which is long-neglected and always wrongly treated.

Impacts of exposure to topical calcineurin inhibitors on metabolism in vitiligo infants.

Background: Tacrolimus ointment is a recently developed topical immunomodulator that has been approved for use in patients with vitiligo older than 2 years. Concern regarding potential systemic toxic effects has limited treatment options for children younger than 2 years. We wanted to determine whether topical tacrolimus therapy is safe and effective in patients with vitiligo younger than 2 years.

Narrowband Ultraviolet B Combined with Topical Simvastatin Solution in the Treatment of Vitiligo: A Case Report.

Phototherapy is one of the treatments for vitiligo. To be specific, the combination of narrowband ultraviolet B (NB-UVB) with topical preparations has currently become the most common therapeutic modality. Moreover, the research on new topical drug has been a hot issue in the field of vitiligo.

Diagnosing of primary cutaneous amyloidosis using dermoscopy and reflectance confocal microscopy.

Background: Primary cutaneous amyloidosis (PCA) is apruritic and potentially disfiguring disorder; this disease is usually diagnosed clinically due to its common occurrence. However, for cases with atypical presentations or for those physicians not familiar with PCA, the diagnosis can be a challenge.

Objective: To observe the characteristics of PCA under dermoscopy and reflectance confocal microscopy (RCM) in order to gain experience and reference for clinicians to facilitate diagnosis.

Neutrophil-to-lymphocyte Ratio: A Biomarker for Predicting Systemic Involvement in Henoch-Schonlein Purpura.

Background: Henoch-Schonlein purpura (HSP) is one of the commonest entities included within the category of cutaneous vasculitis (CV). Our work is purposed to explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) for systemic involvement in Henoch- Schonlein purpura patients. This ratio is known as an inflammatory marker, and is used to assess the systemic inflammation associated with various diseases.

CXCL9 as a key biomarker of vitiligo activity and prediction of the success of cultured melanocyte transplantation.

This study aimed to investigate the potential biomarkers of vitiligo by evaluating the disease activity and curative effect of autologous cultured pure melanocyte transplantation (CMT) on patients. Altogether, 36patients with stable vitiligo were treated with CMT. Blister fluid samples were collected from patients with stable vitiligo.

Altered circulating memory T cells in vitiligo cases followed NB-UVB therapy.

Background: Vitiligo represents a commonly diagnosed autoimmune disease caused by the depletion of epidermal melanocytes. Many subsets of T cells contribute to vitiligo pathogenesis, including resident and circulating memory T cells.

Objectives: To analyze the amounts of CD4 and CD8 memory T-cell subsets in peripheral blood specimens from vitiligo patients and alterations caused by narrowband ultraviolet B (NB-UVB) phototherapy.
