Glucagonomas are rare neuroendocrine neoplasms of the pancreas with malignant potential. At present, their epidemiology is not entirely clear, so clinicians are not well versed, lacking any consensus on diagnosis or comprehensive treatment. The present study reports the case of a 32-year-old woman hospitalized for recurrent glossitis, perioral dermatitis and necrolytic migratory erythema (NME) of both lower limbs. Imaging studies revealed a low-density nodule (~2 cm) in the tail of the pancreas, as well as multiple space-occupying hepatic lesions...

Topical ruxolitinib, a potent Janus kinase (JAK) inhibitor, has shown significant efficacy in treating inflammatory skin conditions. While its use has already been established in atopic dermatitis and vitiligo, recent reports suggest its potential efficacy in treating other dermatoses. Specifically, topical ruxolitinib may be an effective treatment option for refractory dermatological conditions that are inflammation-driven with dysregulated activity of cytokines implicated in the JAK/STAT pathway. In this case series, we present four novel clinical applications of topical ruxolitinib in treatment-resistant dermatological conditions...

Objective: This scoping review aimed to map the adverse reactions in the oral mucosa and face caused by the use of natural products. Methodology: This review was performed according to the Joanna Briggs Institute Manual for Evidence Synthesis and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, with a protocol registered in the Open Science Framework (DOI 10.17605/OSF.IO/R57D8). The search was carried out systematically using PubMed, Scopus, Web of Science, Embase, LILACS, and LIVIVO databases, as well as gray literature through Google Scholar and OpenGrey...

BACKGROUND: Clobetasol has demonstrated remarkable results in treating melasma within a short time frame; however, its use is limited because of the risk of local side effects. To date, there is no controlled trial on sequential clobetasol/hydroquinone for melasma. This study aimed to investigate the tolerability and efficacy of 0.05% clobetasol followed by 4% hydroquinone (CLOB-HQ) in comparison to the isolated use of 4% hydroquinone (HQ). METHODS: A double-blinded, randomized clinical trial involving 50 women with facial melasma was performed...

BACKGROUND: Demodex mites can lead to various skin disorders, from non-specific dermatitis to conditions that mimic other diseases, making it challenging to diagnose accurately. Additionally, it has been reported that Demodex mites can cause skin conditions such as perioral dermatitis, pustular folliculitis, pityriasis folliculorum, blepharitis, and rosacea. Due to conflicting studies, there is a debate regarding the link between Demodex mites and acne vulgaris. This study aims to determine the prevalence of Demodex mites on the faces of individuals with acne vulgaris, acne with nonspecific facial dermatitis, and healthy facial skin to clarify the association...

INTRODUCTION: This is the first report of a patient with severe asthma and atopic dermatitis that developed local perioral skin infection which onset coincided with the patient's treatment with dupilumab (candida albicans) and later with tezepelumab (microscopic detection of yeast). CASE PRESENTATION: Besides moderate headache, macular exanthema was found after administration of tezepelumab, which was subsequently accompanied by a worsening of symptoms upon reexposure to the treatment...

Perioral dermatitis (POD) is a chronic inflammatory skin disease that primarily affects females between the ages of 16 and 45. Conventional therapies face the challenge of limited efficacy and a high recurrence rate. In this report, we present the case of a 26-year-old male patient with POD who was successfully treated using the Janus kinase (JAK) inhibitor, abrocitinib. This treatment exhibited both good efficacy and safety. Abrocitinib, as a JAK inhibitor, holds promise as a potential therapy for cases of POD that might be resistant to conventional therapies...

BACKGROUND: While many studies have reported on occupational allergic contact dermatitis amongst dental personnel, studies on the relevance of patch testing in dental patients are scarce. OBJECTIVES: To determine the frequency and clinical relevance of contact allergy in patients with intra- and perioral complaints. METHODS: A total of 360 patients with intra- and perioral complaints suspected of having a contact allergy were patch-tested with the dental allergen series, European Baseline Series, and extended Amsterdam Baseline Series at Amsterdam University Medical Centers between January 2015 and November 2021...

<u> <i/> </u>There are certain demographic characteristics that may serve as risk factors for exposure to a contact allergen. Volatile alkyl nitrites, colloquially known as "poppers," are commonly inhaled by men who have sex with men (MSM) for their psychoactive and muscle-relaxing effects. They have been reported to cause either allergic contact dermatitis (ACD) or irritant contact dermatitis (ICD), termed "poppers dermatitis." We searched PubMed, Embase, and Web of Science to understand the patient population, clinical presentation, diagnosis, and clinical course of poppers dermatitis...

OBJECTIVE: To evaluate the relationship between the occurrence of contact urticaria in reaction to cow's milk in infants and the diagnosis of cow's milk allergy (CMA) established by supervised oral food challenge. METHODS: In this cross-sectional study, we identified 184 children who had undergone 221 oral food challenge (OFC) at a CMA reference center between July 2015 and August 2019. Of these, 23 (12.5%) had a history of contact urticaria to cow's milk and underwent a total of 30 OFC...

<u>Objectives:</u> Sexual and gender minority (SGM) patients face health issues relevant to dermatologists, such as allergic contact dermatitis (ACD); however, there is a lack of information surrounding common allergens causing ACD that disproportionally affect SGM patients. <u>Methods:</u> Covidence, Embase, MEDLINE, PubMed, Web of Science, and Google Scholar were searched to identify relevant articles studying ACD in the SGM population. <u>Results:</u> Common allergens associated with ACD in SGM patients include nitrates, fragrance mix, methylisothiazolinone, methylisothiazolinone-methylchloroisothiazolinone, topical antibiotics, and allergens seen in chest binders...

Acrodermatitis Enteropathica is a rare hereditary condition characterized by perioral dermatitis, diarrhoea, and alopecia. Aetiology includes autosomal recessive inheritance and acquired causes such as protein malnutrition, malabsorption syndromes, premature births, parenteral nutrition, chronic illnesses, and alcoholism. We report a rare case of a 12-year-old boy who presented with cutaneous manifestations involving the whole body, diarrhoea, and sparse hairs. A low level of plasma zinc, and alkaline phosphatase level was found, and he was started on zinc supplements...

Demodex mites are common ectoparasites of the human pilosebaceous units. Most adults are infested with Demodex mites without clinical symptoms. Demodex mite will only become a pathogenic organism when there is an abnormal increase in the number of Demodex mite density. This situation happens when the equilibrium between Demodex mites, skin microenvironment and human immunity system changes. Demodex infestation can cause multiple skin disorders, which are grouped under the term demodicosis or demodicidosis. Clinical manifestations of demodicosis can mimic other known skin diseases such as folliculitis, rosacea, perioral dermatitis, which is why it is often misdiagnosed...

BACKGROUND/OBJECTIVES: We observed isolated cases of perialar intertrigo in children and teenagers that did not appear to correspond to any known clinical entity. The objective of this study was to describe the clinical features of this dermatosis and the clinical characteristics of the patients. METHODS: We conducted a prospective, multicenter cohort study in France from August 2017 to November 2019. All the patients under 18 years of age with chronic perinasal intertrigo were included...
