Phyllanthus emblica, vitamin E, and caroteinods are compounds showing antioxidative, anti-inflammatory, and repigmenting effects, whose role in vitiligo treatment has not been evaluated so far. Sixty-five subjects (group A) were treated with one tablet of an oral supplement containing P. emblica (100 mg), vitamin E (4.7 mg), and carotenoids (10 mg) three times/day for 6 months and compared with a control group (group B, 65 patients), which instead was not treated with antioxidants. Both groups were simultaneously treated with a comparable topical therapy and/or phototherapy. After a 6 months follow-up, a significantly higher number of patients in group A had a mild repigmentation on the head/neck regions (p = 0.019) and on the trunk (trend, p = 0.051). The number of patients who presented no repigmentation in head/neck, trunk, upper, and lower limbs was significantly higher in group B (respectively, p = 0.009, p = 0.001, p = 0.001, p = 0.025). Moreover, group B patients showed higher signs of inflammation (p = 0.002), a more rapid growth of the lesions (p = 0.039), a higher percentage of worsening disease (p = 0.003), and more erythema (p = 0.059), whereas group A patients showed a higher percentage of steady disease (p = 0.065). Our results suggest that the supplement with antioxidants in patients with vitiligo might represent a valuable instrument to increase the effectiveness of other vitiligo treatments.

The purpose of our study was to verify the results of the association of Q-switched Nd: YAG non-ablative fractionated with intense pulsed light, in order to treat patients with refractory melasma. The combination of these two devices seems to be the best treatment to combat hyperpigmentation produced by melasma, with low occurrence of side effects, which may be justified by the selective photothermolysis at subcellular level.

Traction alopecia is hair loss that occurs after persistent pulling (e.g., during cosmetic procedures) on the roots of hair over time. Unlike plucking, which is painful, persistent pulling may go unnoticed until a patient presents with either bald spots or diffuse telogen shedding. Each hair follicle in the scalp contains an arrector pili muscle that, when contracted, erects the hair. The smooth muscle in the arrector pili expresses α1 adrenergic receptors (α1 -AR). As such, we hypothesized that contraction of the arrector pili muscle via an α1 -AR agonist would increase the threshold of force required to pluck hair during cosmetic procedures. Female subjects, ages 18-40, were recruited to study the effect of topically applied phenylephrine, a selective α1 -AR agonist, on epilation force and hair shedding during cosmetic procedures. In our blinded study, 80% of subjects demonstrated reduced shedding on days using phenylephrine compared to days using a placebo solution. The average reduction in hair loss was approximately 42%. In addition, the force threshold required for epilation increased by approximately 172% following topical phenylephrine application. To our knowledge this is the first study demonstrating the utility of α1 -AR agonists in the treatment of traction alopecia and hair shedding during cosmetic procedures.

Although alginate has been known to be a good wound dressing, it does not have antimicrobial properties, has low availability, and is expensive. In order to overcome these problems, this study was conducted, where the extraction of this material from an available small factory Pseudomonas aeruginosa and the improvement of its wound healing property by its combination with herb extract, Alhagi maurorum, done.

Warts constitute the most frequently observed dermatological manifestations of human papillomavirus (HPV). Although an extensive range of treatments exists for local warts, there is no specific therapy based on high-quality evidence of notable treatment success or high cure rate, or minimal adverse effects. Recalcitrant warts are, therefore, a common therapeutic problem. This case series refer to 14 immunocompetent patients with recalcitrant warts, who experienced full resolution of their warty lesions when treated with addition of low dose isotretinoin, in a dose of 0.1-0.2 mg/kg/day, for a 3-month course, with no significant adverse effects. Long-term remission was noted for up to 3 years with no signs of active lesions. Low dose isotretinoin should be in the priority of the treatment options of recalcitrant warts, alone or in-combination. This article is protected by copyright. All rights reserved.

SJS/TEN are spectrum of rare, acute and life-threatening delayed-type drug hypersensitivity reactions that are associated with high mortality rates. However, no therapeutic standard has been proposed for SJS/TEN. Here, we report a case of a patient diagnosed with Stevens-Johnson syndrome whose disease progression was halted by a single dose of etanercept and was treated successfully. In addition, we reviewed the literature reporting patients with SJS/TEN treated with similar regimens. This article is protected by copyright. All rights reserved.

Pityriasis lichenoides et varioliformis acuta(PLEVA) pemphigoides is an uncommon skin disease, which is characterized by the appearance of blistering skin lesions in patients with PLEVA. We present a 3-year-old boy, who was diagnosed PLEVA pemphigoides. Combined treatment of oral methotrexate and corticosteroids was more effective than corticosteroids alone on this patient.

Basal cell carcinoma is the most frequent malignant neoplasm in white-skinned individuals. It develops in different body areas, including in the scalp, which is a unique anatomical region due to the high number of pilosebaceous follicles; the scalp is protected from UV exposure, a main risk factor for basal cell carcinoma development. Moreover, scalp basal cell carcinoma has been described as more aggressive and difficult to treat than other forms of basal cell carcinoma. In this study, we reviewed the clinical and pathological characteristics, risk factors, genetics, and treatment options for scalp basal cell carcinoma to better understand this special type of cancer. Even though it is not yet clear whether scalp basal cell carcinomas represent a different entity, it seems important to give them special attention due to their potential aggressiveness, invasion capacities, tendency to relapse, and treatment difficulties.

Cutaneous CD30+ lymphoproliferative disorders represent a spectrum of skin lymphatic reticular proliferative diseases, including lymphomatoid papulosis (LYP), primary cutaneous anaplastic large cell lymphoma (PC-ALCL), and borderline lesions between them. Although they all express CD30 as a phenotypic marker and share overlapping immunophenotypic features, they differ in clinical manifestations, pathological features, treatment, and prognosis. LYP is a kind of benign disease characterized by recurrent papules and nodules and may spontaneously regress. PC-ALCL presents with solitary tumor or local grouped nodules characterized by large T-cells and may completely or partially resolve in fewer than half of cases. We reported a case of patient with clinical manifestation and pathologic features consistent with LYP in its early stages, which later turned into PC-ALCL. This patient was treated with acitretin combined with NB-UVB and had an obvious response. This article is protected by copyright. All rights reserved.

Platelet rich plasma (PRP) is essentially an increased concentration of autologous platelets (growth factors) suspended in small amount of plasma. These factors have a proliferative and regenerative effect on a number of tissues in body and have been extensively used in dermatology, surgery, orthopedics and dentistry.
