Recent studies revealed the role of lipase in the pathogenicity of Malassezia restricta in dandruff and seborrheic dermatitis (D/SD). The lipase from M. restricta (Mrlip1) is considered a potential target for dandruff therapy. In this work, we performed structure-based virtual screening in Zinc database to find the natural bioactive inhibitors of Mrlip1. We identified three compounds bearing superior affinity and specificity from the Traditional Chinese Medicine database (~60,000 compounds), and their binding patterns with Mrlip1 were analyzed in detail...

BACKGROUND: Darier disease is a rare autosomal-dominant genodermatosis with a loss of function of a Ca2+ -ATPase pump (SERCA2-pump). Clinically, the disease is characterized by red-brown keratotic papules mainly in seborrheic areas and has only limited and unsatisfactory treatment options. Previously, low-dose naltrexone was described as a successful treatment option in Hailey-Hailey-disease, a genodermatosis with a genetic mutation coding for a similar loss of function of a Ca2+ -ATPase pump (hSPCA1-pump)...

BACKGROUND: Oily skin is one of the most common dermatological complaints. Oily skin may be accompanied by enlarged pores, acne, and seborrheic dermatitis. Moreover, oily skin has negative effects on self-perception. Most therapeutic approaches used to treat oily skin have had varying degrees of efficacy and include topical treatments, such as photodynamic therapy and lasers. However, certain of these therapies for oily skin may lead to severe side effects. With the expanding use and high safety profile of botulinum toxin type A (BoNT-A), its use in the treatment of oily skin has caused significant concerns; moreover, relevant reports have gradually accumulated to address the efficacy of BoNT-A and explore its mechanisms of action...

Seborrheic dermatitis is a common, relapsing, inflammatory skin condition of unclear etiology. The Malassezia yeast genus are believed to play a role. Seborrheic dermatitis commonly affects areas of the skin with high sebum production, including the scalp, nasolabial folds, glabella, eyebrows, beard, ears, retroauricular skin, sternum, and other skin folds. Seborrheic dermatitis may present differently in individuals with skin of color. Darker-skinned individuals may present with scaly, hypopigmented macules and patches in typical areas of involvement...

INTRODUCTION: Although labelling changes and market withdrawal have been implemented for oral ketoconazole (KTZ) due to serious adverse effects, topical KTZ is generally thought to be effective and safe for the treatment of superficial fungal infections. New dermatologic indications for the use of topical KTZ have arisen such as onychomycosis, blepharitis and hair loss. This article aims to review the literature on topical KTZ's efficacy and adverse effects, as well as provide an overview on current insights regarding its mechanism of action and upcoming developments...

Seborrheic keratosis, one of the most common lesions of the epidermis, is rarely seen on mucosal surfaces. We report a case of a distinctive epithelial neoplasm of the esophagus showing close resemblance to seborrheic keratosis that was resected with endoscopic submucosal dissection. A 65-year-old patient's previous esophageal biopsy showed suspicious low grade dysplasia and the patient was referred for endoscopic submucosal dissection of a flat lesion in the mid-esophagus. Macroscopic examination revealed a well circumscribed, pigmented and elevated lesion with a diameter of 20 mm...

Seborrheic keratoses (SK) are the most common skin tumour of humanity. The incidence of this purely benign epithelial proliferation is increasing with age and exposure to ultraviolet light. It has a remarkable variability in its clinical presentation raising some differential diagnoses. Recently, oncogenic mutations have been detected involved in the development of SK, which, however, do not bear the risk of malignant transformation. SK may also develop with the use of modern targeted drugs for the treatment of malignancies...

INTRODUCTION: The dermatologic conditions affecting the male genitalia are diverse and range from normal variants and benign growths to overt malignancy. Unfortunately, there is a dearth of urologic dermatology training in most residency programs, and many dermatologic lesions with a classic appearance on other areas of the body may have atypical presentations on the genitalia. Patients may present to a variety of physicians without receiving a definitive diagnosis, which can be highly distressing to the afflicted individual...

Malignant melanoma is one of the most aggressive forms of skin cancer. Early detection is important as it significantly improves survival rates. Consequently, accurate discrimination of malignant skin lesions from benign lesions such as seborrheic keratoses or benign nevi is crucial, while accurate computerised classification of skin lesion images is of great interest to support diagnosis. In this paper, we propose a fully automatic computerised method to classify skin lesions from dermoscopic images. Our approach is based on a novel ensemble scheme for convolutional neural networks (CNNs) that combines intra-architecture and inter-architecture network fusion...
