Approach to the Patient with Chronic Pruritus.
Lipman, ZM, Ingrasci, G, Yosipovitch, G
The Medical clinics of North America. 2021;(4):699-721
Abstract
Chronic pruritus (itch lasting ≥6 weeks) is a bothersome chief complaint that may present in a broad variety of diseases. Most itch-causing diagnoses fit into 1 of 5 categories (inflammatory, secondary to systemic disease, neuropathic, chronic pruritus of undetermined origin, and psychogenic itch) and this broad differential can be narrowed using key findings in the history and physical. In this article, we discuss which key findings are most pertinent for narrowing this differential and guiding further workup and treatment, as well as how to treat many itchy conditions.

Abstract
Celiac disease (CD) is an immune-mediated enteropathy caused by gluten ingestion, affecting approximately 1% of the worldwide population. Extraintestinal symptoms may be present as the first signs of CD, years before the CD diagnosis is made. A great variety of extraintestinal manifestations may be associated with CD. Cutaneous manifestations represent the main extraintestinal manifestations, with dermatitis herpetiformis being the most common in patients with CD. In adults, it has been demonstrated that the role of a gluten-free diet is crucial not only for the recovery of signs and symptoms associated with CD but also for cutaneous manifestations, which often improve after gluten avoidance. In children with CD, the association with skin disorders is well documented regarding dermatitis herpetiformis, but studies considering other dermatological conditions, such as psoriasis and atopic dermatitis, are few. The prevalence and manifestations of dermatological disorders in celiac children are often different from those in adults, explaining the gap between these populations. In addition, the therapeutic role of a gluten-free diet in the improvement in skin alterations is not fully understood in children and in adult population except for dermatitis herpetiformis. Therefore, cutaneous CD symptoms need to be known and recognized by physicians despite their specialties to improve early CD diagnosis, which is critical for a better prognosis. This review describes the current scientific evidence on skin manifestations associated with CD in the pediatric population.

Daily Lifestyle and Inflammatory Skin Diseases.
Sawada, Y, Saito-Sasaki, N, Mashima, E, Nakamura, M
International journal of molecular sciences. 2021;(10)
Abstract
Throughout life, it is necessary to adapt to the Earth's environment in order to survive. A typical example of this is that the daily Earth cycle is different from the circadian rhythm in human beings; however, the ability to adapt to the Earth cycle has contributed to the development of human evolution. In addition, humans can consume and digest Earth-derived foods and use luxury materials for nutrition and enrichment of their lives, as an adaptation to the Earth's environment. Recent studies have shown that daily lifestyles are closely related to human health; however, less attention has been paid to the fact that obesity due to excessive energy intake, smoking, and alcohol consumption contributes to the development of inflammatory skin diseases. Gluten or wheat protein, smoking and alcohol, sleep disturbance, and obesity drive the helper T (Th)1/Th2/Th17 immune response, whereas dietary fiber and omega-3 fatty acids negatively regulate inflammatory cytokine production. In this review, we have focused on daily lifestyles and the mechanisms involved in the pathogenesis of inflammatory skin diseases.

Safety of anti-TNF agents in pregnancy.
De Felice, KM, Kane, S
The Journal of allergy and clinical immunology. 2021;(3):661-667
Abstract
Inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis are associated with adverse pregnancy outcomes. Active maternal disease during pregnancy is associated with additional negative outcomes. Anti-TNF agents are effective treatments for inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis. These agents cross the placenta starting in the second trimester, with levels detected for several months after birth. This has led to safety concerns, with continued therapy during pregnancy for both the mother and the infant. This review covers retrospective and prospective data published from various cohorts of pregnant women exposed to anti-TNF agents during pregnancy. It highlights the safety of anti-TNF drugs in pregnancy, breast-feeding, and during the first year of life of the infant.

The Potential Uses of Omega-3 Fatty Acids in Dermatology: A Review.
Thomsen, BJ, Chow, EY, Sapijaszko, MJ
Journal of cutaneous medicine and surgery. 2020;(5):481-494
Abstract
BACKGROUND A growing interest exists in the relationship between diet and skin disease, with many recent studies identifying a role for omega-3 fatty acids (O3FAs) in various dermatological conditions. OBJECTIVE Our objective was to identify the spectrum of uses for O3FA supplementation reported in literature and to evaluate the current level of evidence for its clinical application in skin disease prevention and management. METHODS A search was conducted using Ovid MEDLINE for primary literature that examined O3FA intake and skin health. A manual search of reference lists was performed to identify additional articles for inclusion. RESULTS A total of 38 studies met eligibility for review, reporting benefits for O3FA supplementation in the treatment of psoriasis, atopic dermatitis, acne, and skin ulcers. Additionally, a reduced incidence of skin cancer and a decrease in the severity of drug-associated mucocutaneous side effects were reported with O3FA supplementation. CONCLUSION This review yielded many well-studied benefits of O3FA uses in dermatology. Given its high safety profile, low cost, and ease of supplementation, O3FA is a reasonable supplement that may benefit patients wishing to improve inflammatory skin conditions through diet. Areas of particular clinical interest where supplementation may be valuable include O3FAs for systemic UV photoprotection, as well as adjuvant treatment for acne to reduce both inflammatory lesion count and the severity of mucocutaneous side effects associated with isotretinoin use.

Pseudoatrophoderma colli: distinct entity or just a variant of confluent and reticular papilomatosis of Gougerot-Carteaud.
Sudy, E, Urbina, F, Gubelin, W, Misad, C, Espinoza, A
Dermatology online journal. 2020;(10)
Abstract
Pseudoatrophoderma colli is a rare entity described in the same time period as confluent and reticular papillomatosis of Gougerot-Carteaud and the two conditions have certain similarities. Pseudoatrophoderma colli is clinically characterized by lesions with an atrophic and wrinkled appearance, which are mainly located on the trunk and neck (hence the name colli). Few references exist in the literature and most of them are very old. Histopathological findings are nonspecific, showing mild hyperkeratosis, thinning of the stratum granulosum, and acanthosis and papillomatosis in some areas. In the papillary dermis there is vascular dilatation with a sparse inflammatory lymphohistiocytic perivascular infiltrate. Fragmentation of elastic tissue has been described only in one case. There is no specific treatment, with variable responses to diverse therapies including ultraviolet light, vitamin A, lactic acid and minocycline. We describe in detail two patients with pseudoatrophoderma colli and show histology. The first patient was treated with minocycline 100mg per day for two months and the second patient was treated with lymecycline 600mg per day for three months and 300mg per day for another two months. Both patients demonstrated a good response within the first month of treatment.

Amparo, TR, Seibert, JB, Vieira, PMA, Teixeira, LFM, Santos, ODHD, de Souza, GHB
Phytotherapy research : PTR. 2020;(1):94-103
Abstract
The research for new treatments of skin and soft tissue infections (SSTIs) is important due to their high prevalence and number of hospitalizations. The purpose of this review is to address the pathophysiology of SSTIs to highlight the advantages of herbal medicines to their treatment, showing examples of species and compounds with multi-targets action. SSTIs have a complex physiopathology involving the microorganism, as well as inflammation and difficult healing. Therefore, antimicrobial, anti-inflammatory, antioxidant and healing activities are an approach possible for their treatment. Herbal medicines have a wide diversity of biological compounds, mainly phenolic compounds that may act on different targets and also have synergism between them. Therefore, a single medicine may have the four key activities that allied allow eliminating the infection, control the inflammation process and accelerating the healing process, preventing complications with chronic infections.

Fomin, DA, Handfield, K
Cutis. 2020;(1):40-43
Abstract
The ketogenic diet has been therapeutically employed from antiquity and is still utilized today in many disease states. With the boom of the complementary and alternative health movement over the last 2 decades, the lay population has grown more interested in disease prevention and treatment via dietary and lifestyle changes and enhancing health and human performance. The ketogenic diet, whether exclusive or intermittent, has been purported by health care professionals and laypersons alike to meet these demands. In this review article, we look to the current literature for proven and possible mechanisms by which ketones and a ketogenic diet may be utilized in the field of dermatology and direct our readers to pursue further research for this promising potential treatment option.

Hydroxychloroquine in dermatology: New perspectives on an old drug.
Chew, CY, Mar, A, Nikpour, M, Saracino, AM
The Australasian journal of dermatology. 2020;(2):e150-e157
Abstract
Hydroxychloroquine is an age-old drug whose use as an immunomodulatory agent with a low side-effect profile continues to expand. We present a review of this drug including recently updated prescribing recommendations and a summary of its clinical application in dermatology. A maximum daily dose of 5.0 mg/kg based on actual body weight and no greater than 400 mg is advised in order to reduce the risk of retinopathy, which is potentially permanent and has an estimated prevalence of 7.5% at 5 years on standard dosing. Baseline ophthalmologic assessment followed by annual screening after 5 years is recommended; however, closer monitoring should be considered in the setting of existing retinopathy, a cumulative dose > 1000 g or renal dysfunction. Hydroxychloroquine is now considered to be safe in pregnancy, and routine glucose-6-phosphate dehydrogenase (G6PD) deficiency testing is not required. Smoking can significantly decrease its efficacy although the reason is still uncertain. Hydroxychloroquine appears to also demonstrate antineoplastic and cardioprotective benefits.
