RESUMO

INTRODUCTION: Point-of-care ultrasound (POCUS) can assist rheumatologists in monitoring disease activity, establishing diagnoses, and guiding procedural interventions. POCUS use has been increasing, but little is known about current use and barriers among rheumatologists. The purpose of this study was to characterize current POCUS use, training needs, and barriers to use among rheumatologists in practice. METHODS: A prospective observational study of all Veterans Affairs (VA) medical centers was conducted using a web-based survey sent to all chiefs of staff and rheumatology chiefs about current POCUS use, training needs, barriers, and policies. RESULTS: All chiefs of staff (n = 130) and rheumatology chiefs at VA medical centers (n = 95) were surveyed with 100% and 84% response rates, respectively. The most common diagnostic POCUS applications were evaluation of synovitis, joint effusion, tendinopathies, bursitis, and rotator cuff. The most common procedural applications were arthrocentesis and joint, bursa, and tendon injection. Most rheumatology chiefs (69%) expressed interest in training for their group. The most common barriers to POCUS use were lack of trained providers (68%), funding for training (54%), training opportunities (38%), funding for travel (38%), and ultrasound equipment (31%). Lack of POCUS infrastructure was common, and few facilities had POCUS policies (20%), image archiving (25%), or quality assurance processes (6%). CONCLUSION: Currently, half of rheumatology groups use diagnostic and procedural ultrasound applications. Most rheumatology groups desire training, and lack of training and equipment were the most common barriers to ultrasound use. Deliberate investment is needed in ultrasound training and infrastructure for systematic adoption of POCUS in rheumatology. Graphical Abstract available for this article.

RESUMO

Celiac disease (CD) is an immune-mediated disorder of the small intestine triggered by dietary exposure to gluten in genetically susceptible individuals. Adult CD usually has an insidious onset with gastrointestinal symptoms, most often diarrhea and weight loss. The association between CD and reproductive abnormalities has been well described in the literature, but it is uncommon for CD to initially manifest during pregnancy or the postpartum period. We report a case of adult CD in a previously healthy woman with a life-threatening presentation during the postpartum period.

RESUMO

Functional foods, defined as whole foods that provide health benefits beyond their nutritional value, may provide multiple dermatologic benefits. Research studies have documented multiple benefits, including enhanced skin barrier function, improved wound healing, radiance, photoprotection, and hormonal regulation. Although the majority of research to date has involved small-scale human interventions or animal models, promising findings have been noted. A number of potential molecular mechanisms have been described, such as the ability of some foods to combat oxidative stress and thus reduce visible and histologic skin changes in response to UV radiation. Additional mechanisms have been described for wound healing, photo-carcinogenesis, and other outcomes. In this review, we discuss the potential dermatologic role of functional foods in order to advocate for larger-scale, evidence-based, human studies to expand this promising field.

RESUMO

Dietary supplements are regulated as foods by the US Food and Drug Administration (FDA) and, despite their potentially harmful effects, are not subject to labeling rules that apply to prescription medications. This commentary responds to a case about vitamin A supplement safety. The commentary compares regulation of vitamin A-derivative prescription medications, such as isotretinoin, to regulation of high-dose vitamin A supplements, illuminating both products' potential for causing birth defects. Label analysis is key to educating patients about risks of vitamin A-containing supplements. The commentary also suggests the need for more FDA oversight of the dietary supplement industry.

RESUMO

Dietary supplement use is common, with reported use by over half of US adults. This cross-sectional study utilized 2015–2016 National Health and Nutrition Examination Survey data. A total of 9971 respondents were surveyed, of which 3704 reported taking dietary supplements for "healthy skin, hair, and nails." Of those reporting skin supplement use, the majority had health insurance and some college education or above. Many respondents were 19 or younger, were of non-Hispanic White race, had a household income of more than $100,000 per year, and some were pregnant. More than two-thirds of the respondents decided to take the supplements on their own rather than at the advice of a healthcare professional, which is quite alarming. This study helps identify demographic groups more likely to consume skin, hair, and nail supplements. Overall, physicians should educate their patients on dietary supplements to avoid drug-supplement interactions and address the factors that influence the use of over-the-counter skin supplements.

RESUMO

INTRODUCTION: As no centralized database of acne supplements is available, we aimed to provide an overview of these products, with a focus on safety. OBJECTIVES: The objectives of this study were to document the number, formulation, contents, and marketing strategies utilized by acne supplements sold online. METHODS: An online search was conducted between March and May 2020. Products were included in the study if they used the terms: "whitehead", "blackhead", or "acne". Data were extracted from the website, box, and Supplement Facts label. RESULTS: 49 products were identified, which contained 146 unique ingredients. These included vitamins, minerals, food extracts, botanical extracts, amino acids, animal products, and distinct microbial strains. Few (4.1%) products were tested by third parties. CONCLUSIONS: This survey of acne supplements available online raised concerns regarding lack of warning labels, teratogenicity, exceedingly large levels of vitamins and minerals, and lack of third-party testing. Given the limited regulation and oversight of dietary supplements, it is imperative that physicians educate patients on the potential risks of these products.

RESUMO

Stress has multiple and wide-ranging physiologic and clinical impacts on skin disease. This has led to an interest in mind body therapies as potential adjunct treatments for skin disease. The stress response results in the activation of the endocrine, neurologic, and immune systems, with a resulting cascade of impacts, that are both systemic and cutaneous. The 2 main arms of the stress response are the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. The resultant release of cortisol, catecholamines, and neuropeptides has multiple effects. Clinically, these have been shown to increase skin inflammation, increase itching, impair skin barrier function, impair wound healing, and suppress immunity. Mind body therapies are those that focus on the interaction between the mind and the body, with the goal to influence physical function and impact health. These have been shown to ameliorate some of the harmful physiologic changes attributed to stress or to reduce harmful behaviors. In some cases, such as with biofeedback, they may also result in beneficial physiologic changes. Treatments such as meditation, biofeedback, hypnosis, guided imagery, and others have been evaluated in the treatment of skin disease and have shown some benefits. Although randomized controlled trials are limited, these interventions have shown beneficial effects on itching, psychosocial outcomes, and even skin severity. These interventions have been evaluated in diseases such as atopic dermatitis, psoriasis, trichotillomania, and others. Given the potential benefits, improvements in psychosocial outcomes, and a low risk profile, referral to qualified practitioners or multidisciplinary clinics should be considered for some patients.

RESUMO

Consumers of personal care products must be made aware of the potential pitfalls that arise from current labeling practices and regulations. For example, terms such as "hypoallergenic", "sensitive skin", and "baby product" lack legal definitions, and terms such as "fragrance-free" are frequently misinterpreted. Personal care products are a general category that includes such items as cosmetics, drugs, dietary supplements, and consumer goods. This overview of current US FDA regulations of products in this category reviews pertinent regulatory policies and highlights potential consumer pitfalls when evaluating product labels. In particular, current labeling laws permit the use of language that may be incomplete, misinterpreted, or applied solely for marketing purposes. It is important that consumers understand the meaning of labeling terms, the regulations that govern them, and especially understand the potential pitfalls related to these terms.

RESUMO

BACKGROUND: Dietary supplements are popular among US consumers and claim to address a variety of conditions, including acne. Acne supplements containing vitamin A are of particular interest, due to the potentially teratogenic effects of vitamin A doses over 10,000 IU. OBJECTIVE: This study examined dosage, pregnancy risks, and labeling of vitamin A-containing acne supplements available online. METHODS: An Internet search of acne supplements sold online was conducted between March and May 2020. Supplement labels and websites were analyzed for vitamin A content and pregnancy warnings, and then divided into categories based on dosage and teratogenic risk. RESULTS: A total of 49 acne supplements was found, and of these 26 (53%) contain vitamin A. Three supplements are likely teratogenic, 4 contain vitamin A doses exceeding the daily level of intake that meets the nutritional needs of most people, and 15 have an unknown teratogenic risk. Among the 6 supplements with over 10,000 IU vitamin A, 2 have no pregnancy warning at all, including the supplement with the highest vitamin A dose found in this study. CONCLUSIONS: Dietary supplements are not subject to the same stringent regulations as drugs, and as such, consumers may be unaware of pregnancy risks. Furthermore, FDA requirements on labeling of vitamin A supplements may lead to consumer confusion regarding dosage. As such, we encourage stricter labeling requirements for vitamin A-containing supplements, including pregnancy warnings for high-dose supplements and clearer dosage labeling.

RESUMO

Multiple research studies have examined the role of specific dietary interventions and their effects on skin barrier function. The skin barrier is one of the body's first lines of protection against environmental insults, and disruption of this natural line of defense can result in xerosis, irritation, chronic dermatitis, and other cutaneous effects. Multiple laboratory, animal, and human studies have demonstrated that certain dietary interventions have the potential to impact skin barrier function. Measurements of skin barrier function include stratum corneum hydration and transepidermal water loss. In this review, we examine this research and provide an overview of the effects of prebiotics, probiotics, fatty acids, and emerging research on other substances.

RESUMO

Skin, hair, and nail supplements, sometimes referred to as "beauty supplements" or "ingestible skin care," are a large and growing industry. These products may contain vitamins and minerals, sometimes in very high doses. They may also contain herbs, hormones, microbes, or animal derivatives such as fish oils and collagen powders. Dietary supplements are regulated as foods, not as drugs, by the US Food and Drug Administration (FDA). Therefore, manufacturers do not need to provide any proof of safety, efficacy, or quality prior to sale. This is of serious concern, as many adverse effects due to supplement components have been reported. The potential risks cover multiple categories. These include acute toxicities, such as choking, as well as chronic toxicities, such as increased risk of diabetes. Teratogenicity and interactions with drugs and laboratory testing have been documented in research studies. Other risks include potentially increased risk of cancer with long-term use, allergic reactions, and others. It is vital that physicians educate their patients on these risks. As no post-marketing surveillance programs are required for supplements, our understanding of supplement risks is incomplete. Physicians should be wary of these risks and encourage further research and regulation.

RESUMO

BACKGROUND: Dietary supplements promoted for "skin, hair, and nail" health are becoming increasingly popular, although there is a lack of regulatory oversight. As no centralized database or repository for these supplements is available, the aim of this study was to provide an overview of supplements in a sample of retail stores, with a focus on safety concerns. METHODS: Dermatology supplements were defined as those that featured the words "skin", "hair", "nails", "beauty", or "glow" in the product name or tagline. Seven stores including drug, grocery, department, and cosmetics stores were surveyed within a three-mile radius. Data were extracted from the Supplement Facts label of each product. RESULTS: A total of 176 separate supplements were identified, containing a total of 255 distinct ingredients. These included vitamins, minerals, food extracts, botanicals, animal products (collagen, fish oils), amino acids, a hormone, and distinct microbial strains. CONCLUSION: This survey of "dermatology" supplements available in local retailers raised several safety concerns, including potential interactions, teratogenicity risks, a lack of independent third-party testing, lack of warning labels, and nutrient "overdosing". Given limited regulation of dietary supplements, it is imperative that physicians educate patients on the potential risks. These include risks related to supplement ingredients and dosages, as well as risks related to the lack of regulatory oversight. Patients must also be educated about the multiple gaps in our knowledge of dietary supplements, especially in terms of efficacy and long-term safety.

RESUMO

Multiple prescription medications may cause or aggravate acne. A number of dietary supplements have also been linked to acne, including those containing vitamins B6/B12, iodine, and whey, as well as "muscle building supplements" that may be contaminated with anabolic-androgenic steroids (AAS). Acne linked to dietary supplements generally resolves following supplement discontinuation. Lesions associated with high-dose vitamin B6 and B12 supplements have been described as monomorphic and although pathogenesis is unknown, a number of hypotheses have been proposed. Iodine-related acne may be related to the use of kelp supplements and has been reported as monomorphic, inflammatory pustules on the face and upper trunk. Whey protein supplements, derived from milk and used for bodybuilding, are associated with papulonodular acne involving the trunk and sometimes the face. Finally, AAS-induced acne has been described as acne fulminans, acne conglobata, and acne papulopustulosa. With studies indicating that about half of US adults report using dietary supplements, it is important that dermatologists directly ask acne patients about their supplement use and educate them on the potential risks of even seemingly innocuous dietary supplements.

RESUMO

Background and objective Dietary supplements advertised to "boost collagen" or for "skin, hair, and nail" health are becoming increasingly popular, despite a lack of evidence to support their use. These products are not regulated by the United States (U.S.) Food and Drug Administration (FDA), and hence there is no centralized database listing current products. The goal of this study was to document and examine the labeling and marketing methods of these products. Methods Supplements including the words "glow," "beauty," "skin," "hair," or "nails" on the label were included in the sample. Seven stores within a 3-mile radius were included. Results A total of 176 unique supplements were identified. It was found that most products lacked independent testing; many utilized outdated daily values (DVs) of nutrients. Some had confusing dosing instructions, and most products made health-related marketing claims. Conclusion Dermatologists and primary care providers should be aware of the marketing claims commonly made by these products. Patients should be educated that these claims are generally not verified by independent testing agencies, the U.S. FDA, or by high-quality randomized control trials.
