BACKGROUND: Dermoscopy is a common method of scalp psoriasis diagnosis, and several artificial intelligence techniques have been used to assist dermoscopy in the diagnosis of nail fungus disease, the most commonly used being the convolutional neural network algorithm; however, convolutional neural networks are only the most basic algorithm, and the use of object detection algorithms to assist dermoscopy in the diagnosis of scalp psoriasis has not been reported. OBJECTIVES: Establishment of a dermoscopic modality diagnostic framework for scalp psoriasis based on object detection technology and image enhancement to improve diagnostic efficiency and accuracy...

The close interaction between skin and clothing has become an attractive cornerstone for the development of therapeutic textiles able to alleviate skin disorders, namely those correlated to microbiota dysregulation. Skin microbiota imbalance is known in several skin diseases, including atopic dermatitis (AD), psoriasis, seborrheic dermatitis, rosacea, acne and hidradenitis suppurative (HS). Such microbiota dysregulation is usually correlated with inflammation, discomfort and pruritus. Although conventional treatments, that is, the administration of steroids and antibiotics, have shown some efficacy in treating and alleviating these symptoms, there are still disadvantages that need to be overcome...

Seborrheic dermatitis is an inflammatory condition that usually presents with erythema, scaly greasy papules, and plaques affecting sebaceous gland-rich areas and predominantly involving the face and scalp. The diagnosis of seborrheic dermatitis can often be rendered based on the clinical presentation. However, in certain cases, a biopsy can be useful to distinguish it from clinical mimics such as psoriasis, discoid lupus, and rosacea. Prominent sebaceous gland atrophy without scarring has been well-described as an important and relatively specific clue for psoriatic or drug-induced alopecia...

Trace elements are essential for maintaining the body's homeostasis, and their special role has been demonstrated in skin physiology. Among the most important trace elements are zinc, copper, and iron. A deficiency or excess of trace elements can be associated with an increased risk of skin diseases, so increasing their supplementation or limiting intake can be helpful in dermatological treatment. In addition, determinations of their levels in various types of biological material can be useful as additional tests in dermatological treatment...

Netherton syndrome is a rare, autosomal recessive disorder that clinically presents with a triad of congenital ichthyosiform erythroderma, hair shaft abnormalities, and immune dysregulation, which is confirmed with genetic testing for mutations in the serine protease inhibitor Kazal-type 5 (SPINK5) gene. This diagnosis was included in our differential due to the patient's recurring and unimproving rash with desquamating skin. While eczema was included in our differential diagnoses, the patient's systemic symptoms, including failure to thrive, prompted our team to consider other diagnoses...

Diet plays an emerging role in dermatologic therapy. The ketogenic and low-glycemic diets have potential anti-inflammatory and metabolic effects, making them attractive for treating inflammatory skin conditions. We provide an overview of the current evidence on the effects of ketogenic and low-glycemic diets on inflammatory skin conditions including acne, psoriasis, seborrheic dermatitis (SD), atopic dermatitis (AD), and hidradenitis suppurativa (HS). We conclude that low-glycemic diets show promise for treating acne, while the evidence for ketogenic diets in treating other inflammatory skin conditions is limited...

Darier Disease is a rare autosomal dominant inherited skin disorder classified as an acantholytic dermatosis. It manifests around puberty as brownish keratotic papules of skin folds and seborrheic areas, associated with onychopathy and mucosal involvementand have a chronic relapsing-remitting course with frequent exacerbations triggered by sun exposure, heat, friction, or infections. Darier patients have an increased risk of neuropsychiatric disorders, type 1 diabetes and heart failure. Short-term management relies on antibiotics/antiviral, topical corticosteroids and/or retinoids...

Necrotizing infundibular crystalline folliculitis (NICF) is a rare type of necrotizing folliculitis. The disease typically manifests as folliculocentric papules arising in a seborrheic distribution. Only 23 cases exist in the literature. Most reported cases have arisen spontaneously, but a small number of drug-induced cases in the setting of epidermal-derived growth factor, vascular endothelial-derived growth factor, or PD-1 inhibitor therapy have been reported. Colonization by bacteria and/or yeast occurs frequently...

Introduction This study presents an innovative model of integrated dermatology service delivery. Kauri HealthCare (KHC) is a general practice serving around 19 000 patients in Palmerston North, New Zealand. A 'mini clinic' is provided by an on-site dermatologist that is available for patients of KHC. Referring practitioners are required to attend with the patient to present their case and seek dermatologist input. This allows for patients to receive a specialist opinion, as well as for the referrer to receive practical and academic teaching, record findings, and arrange any further investigations, follow-up, or management...

Empirically, in Indonesia, the leaves of Cassia alata L. (candle bush or ketepeng cina) have been used as a topical antifungal agent. Malassezia furfur is a natural microorganism found in the human body. It is among the factors contributing to conditions such as pityriasis versicolor, a common, benign, superficial fungal infection of the skin that is closely associated with seborrheic dermatitis and dandruff. This study aimed to explore C. alata leaves, starting from determining antifungal activity against M...

Background : The umbilicus is a fibrous remnant located in the centre of the abdomen. Various entities may be encountered in this special anatomical location; however, little is known about their dermoscopic presentation. The aim of this study was to provide a comprehensive summary of existing evidence on dermoscopic features of umbilical lesions. Methods : Studies assessing dermoscopic images of umbilical lesions were included in this study. No age, ethnicity or skin phototype restrictions were applied. Papers assessing lesions outside of the umbilical area, lacking dermoscopic images and/or dermoscopic description and not related to the topic were excluded...

IMPORTANCE: Darier disease (DD) is a rare genetic skin disorder caused by heterozygous variants in the ATP2A2 gene. Clinical manifestations include recurrent hyperkeratotic papules and plaques that occur mainly in seborrheic areas. Although some of the lesions wax and wane in response to environmental factors, others are severe and respond poorly to therapy. OBJECTIVE: To investigate the molecular mechanism underlying the persistency of skin lesions in DD. DESIGN, SETTING, AND PARTICIPANTS: In this case series, DNA was extracted from unaffected skin, transient and persistent lesional skin, and blood from 9 patients with DD...

Cutaneous squamous cell carcinoma (CSCC) is the second most common type of skin cancer, after basal cell carcinoma, representing about 10-20% of all malignant skin tumors. The mortality rates of CSCC approach those of renal and oropharyngeal carcinomas, as well as melanoma, with the increasing of the risk once metastases and perineural invasion occur. Both actinic keratosis (AK) and Bowen's disease (BD) are direct precursors with the potential for progression to CSCC. In this study, we analyzed the expression of Ki67, P16 and Beta-catenin in the precursor lesions of CSCC in relation to histological prognostic parameters, respectively between them, with the aim of identifying possible correlations with a role in prognosis...

BACKGROUND: Noninfectious inflammatory dermatoses of the scalp are common, and their symptomsin particular, those affecting appearance, can have a psychological effect that may be disproportionate to their clinical severity. Effective, cosmetically acceptable treatments are important to manage these conditions. Topical corticosteroids form the cornerstone of acute treatment for many of these conditions. We surveyed practicing dermatologists and dermatology residents to determine the current clinical practice in prescribing topical corticosteroids for these disorders in their various preparation formats...

Onychocytic matricoma (OCM) is a benign neoplasm of the nail matrix. Only 18 cases of this tumor have been reported in the literature to date. We retrospectively analyzed the clinical features of 14 patients with OCM. The most common clinical feature was longitudinal xanthopachyonychia (n = 9), followed by longitudinal leukopachyonychia (=3) and longitudinal pachymelanonychia (n = 2). The most common clinical findings identified following dermoscopy and analysis at high magnification of classical photographs were free-edge thickening of the nail plate without pitting (n = 14), longitudinal ridging (n = 7), round white clods (n = 7), white dots (n = 7), and filiform hemorrhages (n = 7), followed by oval and linear white clods (n = 5), fuzzy lateral border (n = 5), and red-purple blood clods (n = 3)...

Pemphigus foliaceus is a superficial blistering disorder characterized by erosions and scaling in a seborrheic distribution. The condition typically occurs in healthy individuals but issues arise from delayed diagnosis. Many cases remain undiagnosed or misdiagnosed due to the lack of awareness of the condition. With use of common diagnostic tools, pemphigus foliaceus can be easily identified and monitored. Histological analysis exhibits "chicken wire" patterning along keratinocytes in the upper epidermis, whereas immunofluorescence study displays subcorneal acantholysis...

Seborrheic dermatitis (SD) is an inflammatory skin disorder and eczema subtype increasingly recognized to be associated with significant physical, psychosocial, and financial burden. The full spectrum of SD, including dandruff localized to the scalp, is estimated to affect half of the world's population. Despite such high prevalence, the exact etiopathogenesis of SD remains unclear. Historically, many researchers have theorized a central, causative role of Malassezia spp. based on prior studies including the proliferation of Malassezia yeast on lesional skin of some SD patients and empiric clinical response to antifungal therapy...
