Noninvasive techniques for nail imaging would be useful for confirming diagnosis and monitoring treatment response at the microscopic level in patients with nail psoriasis. However, the use of ultrasound and high-resolution magnetic resonance imaging in nail evaluation is limited. Optical coherence tomography (OCT) produces high-resolution images of transversal tissue sections and represents an...

BACKGROUND The Randomized Controlled Evaluation of Adalimumab in Treatment of Chronic Plaque Psoriasis of the Hands and Feet (REACH) trial demonstrated that adalimumab was efficacious and well-tolerated for the treatment of hand and/or foot psoriasis through 28 weeks. OBJECTIVE To evaluate the effects of patient baseline characteristics on efficacy of adalimumab treatment of hand and/or foot ...

PURPOSE OF THE STUDY Our aim was to perform an extensive search of the literature on the prevalence of nail psoriasis in the pediatric population and to estimate it on our own database. PROCEDURES Searching the most important databases yielded results of 16 papers published in a 40-year period which reported the prevalence of nail psoriasis in children. Furthermore, data gathered between 2004...

Nail disorders are very common, and about 50% of all nail conditions are of fungal etiology. A proper diagnosis is essential because many nail conditions look alike. Diagnosis and treatment of other nail disorders, such as psoriasis, lichen planus, and neoplasms, are discussed.

Psoriatic arthritis is a spondyloarthropathy which occurs in patients with skin and/or nail psoriasis. Basing its characterization on morphological purposes, several types of arthritis have been described. Alternatively, we propose a simplified classification into three subsets, focusing on the levels of expression of cutaneous and articular elements which devise this syndrome. The first is est...

Background In psoriatic arthritis (PsA), nail disease is intimately linked to the presence of DIP joint enthesitis and arthritis. Nail disease has been shown in clinical trials to respond to treatment with TNF inhibitors. We used high resolution MRI to assess whether improvements in psoriasis-related nail disease correlated to improvements in associated DIP joint enthesitis, osteitis and synovi...

High-frequency B-mode ultrasonography and Doppler study can reveal changes in nail anatomy and vascularization in patients with nail psoriasis (NPs). The primary objective of this study was to describe thumbnail ultrasound findings in a series of adult patients with psoriasis involving the thumbnail. It was decided to focus on the thumbnail as this is the largest finger nail and also the one mo...

The prevalence of nail psoriasis varies considerably among different studies, ranging from 10% to 55%. In psoriatic arthritis, its prevalence is as high as 85%. In spite of the high prevalence of the disease, considerable functional, psychical and cosmetic discomforts for the affected patients, and recent advances in the management of skin psoriasis, an efficacious and longlasting treatment for...

Background: Psoriatic arthropathy is a seronegative arthropathy seen in some patients with psoriasis, a self-limited and genetically determined skin disease. Objective: To determine the prevalence and risk factors of arthropathy in patients with psoriasis. Patients and Methods: In a prospective, cross-sectional study, psoriatic patients referred to Razi Skin Hospital in Tehran, Iran in 20...
