A peel-off facial mask comprising myoinositol and trehalose-loaded liposomes improves adult female acne by reducing local hyperandrogenism and activating autophagy

Summary

Background

Hyperandrogenism and reduced skin autophagy have been implicated in the pathogenesis of adult female acne (AFA). Here, we tested whether a ready-to-use peel-off facial mask containing myoinositol (an androgen inhibitor) and trehalose-loaded liposomes (as activators of cutaneous autophagy) applied overnight every other day for 60 days can improve AFA. We also sought to investigate the molecular mechanisms underlying the clinical effects.

Objectives

We conducted an uncontrolled, open-label clinical study in 40 cases of AFA to investigate the effect of the facial mask on lesion count, sebum production (measured with the Sebutape® technique), and Global Acne Grading System (GAGS) scale. We also investigated the changes from baseline to the end of treatment in androgen and beclin-1 levels (as a marker of authophagy) in skin biopsy supernatants.

Methods

Forty Caucasian patients with AFA were enrolled. Changes in clinical and molecular endpoints before and after treatment were investigated.

Results

The mean counts of comedones, papules, pustules, and nodular lesions decreased significantly (all P<.001). The mean Sebutape® score was reduced from 3.4±0.6 to 1.8±0.2 (P<.001), whereas the mean GAGS scale score decreased from 16.8±5.3 at baseline to 9.8±4.6 after treatment (P<.001). A significant decrease in testosterone and dehydroepiandrosterone sulfate in skin biopsy supernatants was observed, whereas beclin-1 levels increased significantly (P<.001).

Conclusion

A ready-to-use peel-off facial mask containing myoinositol and trehalose-loaded liposomes improved the cosmetic appearance of AFA by reducing cutaneous androgen content and promoting skin autophagy.

Overexpression of Drosha, DiGeorge syndrome critical region gene 8 (DGCR8), and Dicer mRNAs in the pathogenesis of psoriasis

Summary

Introduction

Psoriasis is a complex autoimmune inflammatory disease that occurs in genetically susceptible individuals and presents with the development of inflammatory plaques on the skin. Recent studies have indicated that microRNAs (miRNAs) play important roles in psoriasis.

Objective

To investigate whether expression of Drosha, DGCR8, and Dicer mRNAs is involved in the pathogenesis of psoriasis.

Methods

Biopsies were obtained from involved psoriatic skin (PP), noninvolved psoriatic skin (PN), and healthy skin (NN). Expression of Drosha, Dicer, and DGCR8 was assessed with real-time quantitative real-time PCR in 25 patients with psoriasis and 25 healthy volunteers.

Results

We observed that expression levels of Drosha, Dicer, and DGCR8 were upregulated in patients with psoriasis compared to the control group. However, the Drosha and Dicer expression levels were higher in PP tissues and PN tissues compared to NN tissues, but they were more upregulated in PP tissues compared to PN tissues (P<.001). Although the DGCR8 expression was higher in PP tissues and PN tissues compared to NN tissues, it was more upregulated in PN tissues compared to PP tissues (P<.001).

Conclusion

Our data demonstrate that upregulated expression of Drosha, DGCR8, and Dicer mRNAs may be involved in the pathogenesis of psoriasis.

Acral lentiginous melanoma versus other melanoma: A single-center analysis in Japan

Abstract

We summarize herein our 14-year experience of conventional treatment outcomes before the era of molecular-targeted therapy and immunotherapy. Specifically, we conducted a retrospective review of our 252 patients with primary cutaneous melanoma (acral lentiginous melanoma [ALM], n = 121; non-acral lentiginous melanoma [non-ALM], n = 131), and compared the prognostic factors between ALM and non-ALM. Melanoma-specific survival and disease-free survival were estimated using the Kaplan–Meier method. Regarding the results, all patients were Japanese (106 male and 146 female), with a mean age of 60.1 years. Among ALM patients, age was elder and primary tumor size was larger than non-ALM. As for tumor thickness, in situ lesions were more frequently observed in ALM. There was no significant difference in the distribution of tumor thickness between the two groups when excluding the in situ lesions. For treatment of the primary melanoma, 248 patients (98.4%) had undergone curative surgical excision and 120 patients with more than 1 mm or ulcerated melanoma had undergone sentinel lymph node biopsy. Patients with systemic metastasis primarily underwent dacarbazine-based chemotherapy. The Kaplan–Meier survival curves revealed no significant difference in melanoma-specific survival and disease-free survival between those with ALM and non-ALM. The results also showed that both ALM and non-ALM, when they initially metastasize, first affect the regional lymph nodes. Incisional biopsy was not an adverse prognostic factor. These results suggest that ALM does not differ in its biological behavior from non-ALM, so we can consider ALM as being equivalent to non-ALM. The initial treatment for ALM and non-ALM can involve the same strategy.
