Importance: During the coronavirus disease 2019 (COVID-19) pandemic, several cases of chilblains have been reported.

Objective: To determine if chilblains are associated with COVID-19.

Design, Setting, And Participants: This monocentric case series was conducted at the Department of Dermatology at Cliniques universitaires Saint-Luc, a tertiary care hospital in Brussels, Belgium, between April 10 and April 17, 2020.

The preservative 2-(thiocyanomethylthio)benzothiazole: A potential allergen in leather products.

Background: Allergic contact dermatitis caused by leather is common, and several responsible allergens, such as tanning agents, glues, mercaptobenzothiazole derivatives, and dyes, but also antimicrobials and antifungals, are involved.

Material And Methods: Three female patients were referred to the Departments of Dermatology in a Belgian university hospital following skin reactions caused by leather products (shoes, belt, and car seats). They were patch tested with the European baseline series and samples of suspected leather products, and additionally with 2-(thiocyanomethylthio)benzothiazole (TCMTB), an antifungal agent previously reported to be a contact allergen in footwear.

Dermatology today and tomorrow: from symptom control to targeted therapy.

For many decades and until recently, medical approach to dermatologic diseases has been based on the physician's ability to recognize and treat symptoms. Nowadays, advances in the understanding of the biology of diseases and in technologies for intervening against them have allowed physicians to diagnose and treat underlying disease processes rather than simply addressing the symptoms. This means that rather than addressing 'the disease in humans', physicians can now address the particular pathologic (biologic, molecular) disturbance as it presents in the individual patient, i.

Gerontodermatology: the fragility of the epidermis in older adults.

The proportion of adults over 60 years of age is rapidly increasing and is estimated to reach approximately one-sixth of the global population by 2030. An ageing population is a real challenge for healthcare resources, including dermatologists and geriatricians, as age-related changes in skin integrity and barrier function make older adults more susceptible to developing skin pathologies such as pruritus, dermatitis and infections. Fragile skin arises from several interlinked causes, including age-related changes in skin barrier integrity, previous and current lifestyle choices, skin pathologies and medical interventions.

[Adverse effects of hair care in users].

The panoply of products used by hair care professionals to wash, dye, shape and beautify hair is not entirely free from adverse events. Such effects consist mainly of irritation dermatitis and allergic contact eczema affecting the scalp, as well as the back and front of the neck, the forehead and periorbital areas, and the cheeks. The most frequently cited allergens include paraphenylenediamine (PPD) in hair dyes, glycerol monothioglycolate (GMTG) in acid perm lotions, and ammonium persulphate in hair lighteners (the latter substance being responsible primarily for contact urticaria).

Acne across Europe: an online survey on perceptions and management of acne.

Background: Acne is common among young people.

Objective: To describe the burden, management and sources of advice of acne in a representative sample of young people in Europe.

Methods: This cross-sectional survey was conducted in a representative sample of individuals aged 15-24 years from Belgium, Czech and Slovak Republics, France, Italy, Poland and Spain (n = 3099).

Allergic contact dermatitis caused by isobornyl acrylate in Freestyle® Libre, a newly introduced glucose sensor.

Background: Glucose sensors, such as FreeStyle® Libre, are innovative medical devices developed for diabetes patients as a replacement for classic glucose meters, ensuring continuous glucose monitoring without the disadvantage of regular skin finger pricks.

Objectives: To report several cases of allergic contact dermatitis caused by FreeStyle® Libre, and to report on isobornyl acrylate as a culprit allergen.

Patients And Methods: Fifteen patients presented with allergic contact dermatitis caused by FreeStyle® Libre.

Acne prevalence and associations with lifestyle: a cross-sectional online survey of adolescents/young adults in 7 European countries.

Background: Although acne vulgaris is a common skin disorder, limited epidemiological data exist specifically for European populations.

Objective: To determine the prevalence of self-reported acne among young people in Europe and evaluate the effect of lifestyle on acne.

Methods: We conducted a cross-sectional population-based online survey in representative samples of individuals aged 15-24 years in Belgium, Czech and Slovak Republics, France, Italy, Poland and Spain (n = 10 521), identified by a quota sampling method based on age, geographic location and socio-professional category.

Fragility of epidermis in newborns, children and adolescents.

Within their first days of life, newborns' skin undergoes various adaptation processes needed to accommodate the transition from the wet uterine environment to the dry atmosphere. The skin of newborns and infants is considered as a physiological fragile skin, a skin with lower resistance to aggressions. Fragile skin is divided into four categories up to its origin: physiological fragile skin (age, location), pathological fragile skin (acute and chronic), circumstantial fragile skin (due to environmental extrinsic factors or intrinsic factors such as stress) and iatrogenic fragile skin.

Crohn's Disease treated with azathioprine and basal cell carcinoma : three cases and literature review.

Three cases of basal cell carcinoma in Crohn's disease patients treated with azathioprine are described. A review of the literature is conducted concerning this association between the occurrence of basal cell carcinoma and the use of azathioprine. Recently, practical advice on screening and follow-up of these situations have been proposed but there are no validated dermatological recommendations.

Eight Novel Mutations Confirm the Role of AAGAB in Punctate Palmoplantar Keratoderma Type 1 (Buschke-Fischer-Brauer) and Show Broad Phenotypic Variability.

Punctate palmoplantar keratoderma (PPKP1; Buschke-Fischer-Brauer) is a rare autosomal dominant inherited skin disease characterized by multiple hyperkeratotic papules involving the palms and soles. Mutations have been found at 2 loci, on chromosomes 15q22-15q24 and 8q24.13-8q24.

Acute visual loss following dapsone-induced methemoglobinemia and hemolysis.

Objective: While methemoglobinemia is a possible complication of chronic dapsone therapy or of acute overdose, serious adverse manifestations related to methemoglobin formation remain rare. We present an unusual case with severe ischemic retinal injury.

Case Report: A 30-year-old African woman presented with a sudden decrease of visual acuity secondary to retinal ischemia.

Fragility of epidermis and its consequence in dermatology.

The skin is the largest organ of the body, providing a protective barrier against bacteria, chemicals and physical insults while maintaining homeostasis in the internal environment. Such a barrier function the skin ensures protection against excessive water loss. The skin's immune defence consists of several facets, including immediate, non-specific mechanisms (innate immunity) and delayed, stimulus-specific responses (adaptive immunity), which contribute to fending off a wide range of potentially invasive microorganisms.

A case of transient lymphangiectasis of the penis.

Objective And Importance: Physicians are likely to encounter patients with penis disorders and can be caught off guard by these uncommon pathologies, especially because they occur in a sensitive anatomical location.

Clinical Presentation: Here, we report the case of a patient presenting with benign transient lymphangiectasis of the penis (BTLP), including its differential diagnosis and treatment. Conclusion headings: BTLP is not an uncommon pathology and diagnosis is based only on medical history and clinical examination.

The European Standard Series and its additions: are they of any use in 2013?

This study has two purposes:--to know whether the European standard series is still the key reference when it comes to contact dermatitis, i.e., are its components still the most frequently involved allergens in contact dermatitis nowadays?--to assess the results of the European standard series among French and Belgian dermatologists/allergists as, so far, most of them have failed to provide statistical data within the European community of allergists/dermatologists.

Characterization of the T cell response in allergic contact dermatitis caused by corticosteroids.

Background: Delayed allergic hypersensitivity reactions have classically been described as type IV reactions, which are caused by T cells; however, the respective roles of CD4(+) and CD8(+) cells are yet to be defined. A central role for CD8(+) cytotoxic T cells as effector cells has been suggested.

Objectives: To determine the type of T cell involved in corticosteroid allergy.
