Allergens in Common Brands of Clobetasol.

BACKGROUND: Allergic contact dermatitis (ACD) may occur secondary to topical corticosteroids. This may be due to topical corticosteroids containing potential allergens in their vehicles. Variation of allergenic ingredients among various brands of a product has not been well characterized. OBJECTIVE: This study aimed to assess the frequency of allergenic ingredients in various brands and manufacturers of clobetasol propionate. METHODS: Common brands of clobetasol propionate were identified online on GoodRx website. Then, ingredient lists for these products were obtained from the US Food & Drug Administration’s Online Label Repository via a proprietary name search. A systematic literature review was performed using the ingredient name on Medline (PubMed) database to find reports of ACD confirmed by patch testing. CONCLUSIONS: Forty-nine different ingredients were identified among all 18 products included, with an average of 8.4 ingredients per product; 19 of these ingredients have allergenic potential, while one has protective effects. Two branded foam formulations contained the greatest number of potential allergens (5), while a shampoo formulation contained no potential allergens. Knowing which allergens are present in different products may be helpful when treating a patient with an allergy or suspected allergy to one of these ingredients.

Tools of dermatology: A historical perspective.

Dermatology is one of the few visual specialties; much can be seen with the naked eye, yet many tools and devices can facilitate the diagnosis of cutaneous maladies. There has been significant progress in diagnostic techniques in recent decades with the advent of artificial intelligence and teledermatology. Such advancements reflect principles of long-standing aids, whereas others embody novel techniques and concepts. These bedside tools range from simple magnifiers and binocular loupes to reflectance confocal microscopes and ultrasounds. The cornerstone diagnostic techniques, including the potassium hydroxide examination and the Tzanck smear, remain highly useful. Although visual examination often permits an accurate diagnosis of a skin disease, the clinician is now even further equipped. Just as the microscope did 4 centuries ago, newer advances will continue to revolutionize the practice of medicine.

Digital future of dermatology.

Evolution of technology in the past several decades has undeniably transformed the practice of medicine. Dermatology, a field relying on visual cues, has been particularly impacted by advancement in imaging technologies. The purpose of this study was to review the current status as well as digital future of dermatology. The PubMed database was searched for articles pertaining to digital dermatology using search terms digital dermatology, teledermatology, and dermatopathology education. Digital dermatology has found a role in almost every aspect of dermatology: research, dermatology education and training, and clinical practice including disease prevention, diagnosis, treatment, and patient follow-up. Smartphone applications such VisualDx, MyDermPath, YouDermoscopy serve as diagnostic aid tools and can also help increase the user's knowledge of dermatology. Tools such as multispectral digital skin lesion analysis (MSDSLA) improve diagnostic accuracy and lead to fewer unnecessary biopsies. Teledermatology increases patient satisfaction, as they are able to experience shorter waits times and decreased costs. Underserved communities and those in rural settings are more likely to have a dermatologic evaluation by a specialist via teledermatology. Addressing important topics such as legal framework and updating reimbursement policies will allow for a smoother incorporation of digital dermatology into clinical practice and likely benefit patient care.

Unilateral contact dermatitis of the chest.

Unusual distributions of contact dermatitis often lead to identification of the offending agent. We present a case of unilateral dermatitis of the chest developing in a patient with a history of allergy to metal. A name tag attached magnetically to his work uniform was identified as the cause of the eruption. Unilateral eruption of the chest can be a manifestation of allergic contact dermatitis to metal objects in breast pockets or attached to clothing.
