Recommendations for the definition, evaluation, and treatment of nail psoriasis in adult patients with no or mild skin psoriasis: a dermatologist and nail expert group consensus.

J Am Acad Dermatol 2019 Feb 4. Epub 2019 Feb 4.

Greater Miami Skin and Laser Center, Department of Dermatology, Herbert Wertheim College of Medicine, Florida International University, Miami, Florida, USA.

Nail involvement in psoriasis is common, and the severity of it does not always parallel the intensity of cutaneous disease. We created a consensus group, of which the aim was to provide practical recommendations for the treatment of nail psoriasis in patients without skin psoriasis, or with mild skin lesions with no indication for a systemic treatment. This collaborative process was conducted by an international panel of dermatologists with special expertise in nail disorders, using a formal consensus methodology. Read More

Nail Psoriasis: An Updated Review and Expert Opinion on Available Treatments, Including Biologics.

Acta Derm Venereol 2018 12 6. Epub 2018 Dec 6.

Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Via Massarenti 1, IT-40138 Bologna, Italy.

Nail psoriasis affects 50-79% of patients with skin psoriasis and up to 80% of patients with psoriatic arthritis, and can also represent a negative prognostic factor in individuals with plaque psoriasis. Treatments for nail psoriasis are limited, as nails are often difficult to treat with topical therapies alone, and relapse is common. Among different systemic agents, secukinumab, a fully human monoclonal antibody targeting interleukin (IL)-17A, is the only antibody supported by a trial specifically conducted in patients with nail psoriasis (the TRANSFIGURE trial) and has the longest follow-up available to date.

Cureus 2018 Jul 5;10(7):e2929. Epub 2018 Jul 5.

Dermatologist, San Diego Family Dermatology, San Diego, USA.

A sign is a physical feature or microscopic change which can be observed when the patient or their tissue specimen is evaluated. An astute clinician or pathologist may be able to diagnose a patient's condition by recognizing this unique morphologic feature or pathological change. In dermatology, the flag sign-alternating transverse bands of the skin or its adnexal structures that are analogous to the alternating colors of the stripes of a flag-has been associated with distinctive disorders of the hair, skin, or nails.

Clinical outcomes and feasibility of the multidisciplinary management of patients with psoriatic arthritis: two-year clinical experience of a dermo-rheumatologic clinic.

Clin Rheumatol 2018 Oct 29;37(10):2741-2749. Epub 2018 Jul 29.

Clinica Medica, Dipartimento Scienze Cliniche e Molecolari, Università Politecnica delle Marche, Via Tronto 10/A, 60126, Ancona, Italy.

Psoriatic arthritis (PsA) is a chronic inflammatory autoimmune arthritis, occurring in patients with psoriasis (Pso), that may affect the whole musculoskeletal system but also nails, eye, and gastrointestinal tract. Dermatologists and rheumatologists usually manage Pso and PsA separately, but early diagnosis and integrated management could achieve better outcomes of both skin and musculoskeletal manifestations, thus improving the health-related quality of life (HRQoL) of patients. In this work, we have described a model of integrated dermo-rheumatologic approach for the early diagnosis of PsA and to present the outcomes of the multidisciplinary management of PsA patients after 48 weeks of follow-up.

Underdiagnosed and undertreated psoriasis: Nuances of treating psoriasis affecting the scalp, face, intertriginous areas, genitals, hands, feet, and nails.

Dermatol Ther 2018 05 6;31(3):e12589. Epub 2018 Mar 6.

Department of Rheumatic and Immunologic Diseases, Cleveland Clinic, Cleveland, Ohio.

Psoriasis of the scalp, face, intertriginous areas, genitals, hands, feet, and nails is often underdiagnosed, and disease management can be challenging. Despite the small surface area commonly affected by psoriasis in these locations, patients have disproportionate levels of physical impairment and emotional distress. Limitations in current disease severity indices do not fully capture the impact of disease on a patient's quality of life, and, combined with limitations in current therapies, many patients do not receive proper or adequate care.

Department of Pharmacology, Pharmacy and Pharmaceutical Technology, University of Santiago de Compostela, Spain; Industrial Pharmacy Institute, University of Santiago de Compostela, Spain. Electronic address:

Soluble derivatives of β-cyclodextrin (CD) have a high capacity to solubilise hydrophobic molecules and to interact with proteins and membrane component. As consequence CD derivatives shows a significant activity as drug absorption enhancers through different delivery routes, such as the oral, nasal, ocular or topical route. In this paper, the effect of two CD derivatives -methyl-β-cyclodextrin (MBCD) and hydroxypropyl-β-cyclodextrin (HPB)- on the structure and permeability of the nail plate has been studied using the drug model ciclopirox olamine.

Eckart Haneke

Psoriasis (Auckl) 2017 16;7:51-63. Epub 2017 Oct 16.

Department of Dermatology, Inselspital, University of Bern, Bern, Switzerland.

Psoriasis is the skin disease that most frequently affects the nails. Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia.

Altered Bone Remodeling in Psoriatic Disease: New Insights and Future Directions.

Calcif Tissue Int 2018 05 12;102(5):559-574. Epub 2018 Jan 12.

Allergy, Immunology & Rheumatology Division, University of Rochester Medical Center, Rochester, NY, 14623, USA.

Psoriatic arthritis (PsA) is an inflammatory rheumatic disorder that occurs in patients with psoriasis and predominantly affects musculoskeletal structures, skin, and nails. The etiology of PsA is not well understood but evidence supports an interplay of genetic, immunologic, and environmental factors which promote pathological bone remodeling and joint damage in PsA. Localized and systemic bone loss due to increased activity of osteoclasts is well established in PsA based on animal models and translational studies. Read More
