Scabies is a contagious skin condition caused by the Sarcoptes scabiei mite. It can lead to various clinical reactions, ranging from no symptoms at all to noticeable skin lesions and severe itching within the same household. We aimed to investigate the potential role of blood groups in the emergence of disease symptoms by comparing the scabies patients with asymptomatic co-residents. This study comprised 102 patients infected with scabies from index cases and 111 asymptomatic co-residents. The index cases where symptoms first appeared were excluded...

BACKGROUND: Helicobacter pylori (H. pylori) is a gastric Gram-negative, spiral-shaped microaerophilic pathogen. H. pylori may play a potential pathogenic role in extra-intestinal diseases such as hepatobiliary, respiratory, and dermatological disorders. The latter included chronic urticaria, psoriasis and rosacea. The first report in literature on the relationship between H. pylori and acne vulgaris (AV), found association between severe AV and H. pylori infection. There are very limited data in AV patients addressing the impact of H...

BACKGROUND: Oral isotretinoin causes changes in serum lipid values. These changes are not seen in every patient, regardless of dose. It is unclear what causes these changes and how often serum lipid values should be followed up. AIMS: We aimed to evaluate the relationship between the change in serum lipid values and personal and familial risk factors. METHODS: Serum lipid values at baseline (0th), 1st, 3rd, and 6th months of isotretinoin treatment of acne patients aged 16 years and over using oral isotretinoin at a dose of 0...

Keloids are characterized histologically by excessive fibroblast proliferation and connective tissue deposition, and clinically by scar tissue extending beyond the original site of skin injury. These scars can cause pruritus, pain, physical disfigurement, anxiety, and depression. As a result, keloid patients often have a diminished quality of life with a disproportionate burden on ethnic minorities. Despite advances in understanding keloid pathology, there is no effective Food and Drug Administration (FDA)-approved pharmacotherapy...

Mohs micrographic surgery is the gold standard for treating many types of skin cancer, particularly skin cancers of high-risk areas such as the face, genitalia, and digits, due to its tissue-sparing technique and low recurrence rates. The use of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies has yet to be explored in a systematic review. The authors sought to assess outcomes including recurrence rates of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies...

BACKGROUND: One of the hereditary syndromes associated with multiple early-onset basal cell carcinomas (BCCs) is basal cell nevus syndrome (BCNS), of which a minority is caused by germline SUFU mutations. Germline SUFU mutations show a spectrum of phenotypes, of which multiple hereditary infundibulocystic basal cell carcinoma syndrome (MHIBCC) is one. Patients with MHIBCC develop multiple basaloid skin tumors from middle age onwards. METHODS: Three patients presenting with an MHIBCC phenotype were tested for a germline SUFU mutation...

Malignant melanoma, a cancer type with a high mortality rate and increasing incidence worldwide, primarily affects the skin but can also occur in various other organs and tissues, including the respiratory tract. Although primary lung malignant melanomas are rare, they are often diagnosed at advanced stages due to their asymptomatic nature, and their atypical presentations may lead to misdiagnosis as other malignancies. In this case report, a mass lesion almost completely filling the right lung initially led to the consideration of small cell lung carcinoma, but a definitive pathological diagnosis could not be obtained in subsequent studies...

Although much has been written about peer review science, practical advice on HOW to peer review articles is lacking, especially for Dermatology. This article aims to provide a practical, stepwise framework to support new reviewers. Step 1 involves a rapid read of the manuscript to get a feel of the topic and to clarify the study question and design. Step 2 is a thorough slower read, using an appropriate EQUATOR checklist. Step 3 is to organise your comments to authors into major and minor points in a constructive way, focusing on clarity of question, internal validity, external validity and whether interpretation fits with the results...

The use of omega-3 fatty acids (omega-3 FA) in the treatment of atopic dermatitis (AD) is an area of ongoing research. Some studies suggest that dietary supplementation with omega-3 FA can help manage symptoms of AD by reducing lesion severity, skin inflammation, dryness and itching, while others show no significant beneficial effect. The aim of this study was to evaluate the effect of omega-3 FA from fish oil in combination with gamma-linolenic acid (GLA) from blackcurrant seed oil in children with AD. This is a longitudinal, prospective, randomized, triple blind, placebo-controlled parallel clinical trial...

In recent years, a wide variety of high-performance and versatile nanofiber membranes have been successfully created using different electrospinning methods. As vehicles for medication, they have been receiving more attention because of their exceptional antibacterial characteristics and ability to heal wounds, resulting in improved drug delivery and release. This quality makes them an appealing choice for treating various skin conditions like wounds, fungal infections, skin discoloration disorders, dermatitis, and skin cancer...

Plants are a rich source of secondary metabolites, among which phenolics are the most abundant. To date, over 8000 various polyphenolic compounds have been identified in plant species, among which phenolic acids, flavonoids, coumarins, stilbenes and lignans are the most important ones. Acne is one of the most commonly treated dermatological diseases, among which acne vulgaris and rosacea are the most frequently diagnosed. In the scientific literature, there is a lack of a detailed scientific presentation and discussion on the importance of plant phenolics in the treatment of the most common specific skin diseases, e...

The therapeutic properties of turmeric essential oil have been extensively documented in both preclinical and clinical studies. Research indicates that its primary active compounds are promising candidates for addressing a wide range of pathologies, exhibiting anticancer, anti-inflammation, antioxidant, cardiovascular, hypoglycemic, dermatological, hepatoprotective, neurological, antiparasitic, antiviral, insecticidal, antifungal, and antivenom activities. While numerous compounds possess similar potential applications, the isolated active constituents of turmeric essential oil stand out due to their unique pharmacological profiles and absence of toxicity...

Background: Advancements in managing stage III melanoma have involved the implementation of adjuvant therapies alongside a simultaneous decrease in the utilization of completion lymph node dissection (CLND) following positive sentinel node biopsy (SLNB). Methods: This retrospective study from the University of Turin's Dermatology Clinic analyzed relapse-free survival (RFS) and overall survival (OS) among stage III melanoma patients (n = 157) who underwent CLND after positive SLNB versus those who did not receive such procedure...

Background : Oncological anxiety associated with biological therapy is a particular challenge in inflammatory bowel disease (IBD), and it has raised questions about the need for the dermatological assessment of the skin before starting biological therapy. Methods : The aim of this study was to assess the frequency of dermal lesions, including cutaneous malignancies, in IBD patients. This retrospective, single-center study evaluated 805 IBD patients who qualified for biological treatment and were subjected to a dermatological assessment...

Background: Over the past 20 years, the treatment scenario of multiple sclerosis (MS) has radically changed, and an ever-increasing number of disease-modifying treatments has emerged. Among high-efficacy treatment agents, monoclonal antibodies (mAbs) have become a mainstay in a MS patient's treatment due to their targeted mechanism, high efficacy, and favorable risk profile. The latter varies from drug to drug and a skin cancer warning has emerged with sphingosine 1-phosphate receptor inhibitors. Several cases of skin malignancy in people with MS (pwMS) undergoing therapy with mAbs have also been described, but dermatological follow-up is not currently indicated...

Chemotherapy poses both physical and psychological challenges for patients, prompting many to seek answers independently through online resources. This study investigates German Google search behavior regarding chemotherapy-related terms using Google AdWords data from September 2018 to September 2022 to gain insights into patient concerns and needs. A total of 1461 search terms associated with "chemotherapy" were identified, representing 1,749,312 to 28,958,400 search queries. These terms were categorized into four groups based on frequency and analyzed...

Skin ageing is influenced by both intrinsic and extrinsic factors, with excessive ultraviolet (UV) exposure being a significant contributor. Such exposure can lead to moisture loss, sagging, increased wrinkling, and decreased skin elasticity. Prolonged UV exposure negatively impacts the extracellular matrix by reducing collagen, hyaluronic acid, and aquaporin 3 (AQP-3) levels. Fermentation, which involves microorganisms, can produce and transform beneficial substances for human health. Natural product fermentation using lactic acid bacteria have demonstrated antioxidant, anti-inflammatory, antibacterial, whitening, and anti-wrinkle properties...

This study was carried out at the Dermatologic Clinic of the University of Turin, Italy, to assess the effectiveness and safety of adjuvant therapy in patients who received either targeted therapy (TT: dabrafenib + trametinib) or immunotherapy (IT: nivolumab or pembrolizumab) for up to 12 months. A total of 163 patients participated, including 147 with stage III and 19 with stage IV with no evidence of disease. The primary outcomes were relapse-free survival (RFS), distant metastasis-free survival (DMFS), and overall survival (OS)...

Accurate skin diagnosis through end-user applications is important for early detection and cure of severe skin diseases. However, the low quality of dermoscopic images hampers this mission, especially with the presence of hair on these kinds of images. This paper introduces DM-AHR , a novel, self-supervised conditional diffusion model designed specifically for the automatic generation of hairless dermoscopic images to improve the quality of skin diagnosis applications. The current research contributes in three significant ways to the field of dermatologic imaging...

Background: Canine otitis externa is a common presentation in small animal practice. The clinical signs vary individually from patient to patient. Regardless of the expression, they all decrease the quality of life. Therefore, this study aimed to identify factors that showed reduced odds for otitis externa. Methods: Clinical case records were searched for key terms regarding canine otitis. Statistical analyses were applied to evaluate associations with otitis externa. p -values of <0.05 were considered statistically significant...
