Prevalence of interdigital psoriasis of the feet ("psoriasis alba") in mild, moderate, and severe psoriasis.

Interdigital psoriasis of the feet ("psoriasis alba") is a rare form of inverse psoriasis. We conducted a cross-sectional study of the prevalence of interdigital psoriasis in mild, moderate, and severe psoriasis, compared to atopic dermatitis and normal controls. Data were collected during 2010-2013 from 232 psoriatic patients, 190 patients with atopic dermatitis, and 202 normal controls.

Two Novel Homozygous Desmoplakin Mutations in Carvajal Syndrome.

Background: Mutations in various desmosomal proteins were shown to cause inherited forms of cardiomyopathy. Carvajal syndrome (Online Mendelian Inheritance in Man [OMIM] 605676) is characterized by the association of dilated cardiomyopathy, striate palmoplantar keratoderma, and woolly hair. It is caused by homozygous as well as heterozygous mutations in DSP, which encodes the desmosomal plaque protein desmoplakin.

Excoriation (skin-picking) disorder in adults: a cross-cultural survey of Israeli Jewish and Arab samples.

Objective: We sought to estimate the lifetime prevalence of Excoriation (Skin-Picking) Disorder (SPD) in the Israeli adult population as a whole and compare SPD prevalence in the Jewish and Arab communities. We also explored demographic, medical and psychological correlates of SPD diagnosis.

Methods: Questionnaires and scales screening for SPD, and assessing the severity of perceived stress, depression, obsessive-compulsive disorder (OCD), body dysmorphic disorder (BDD), alcohol use, illicit drug use, and medical disorders were completed in a sample of 2145 adults attending medical settings.

Prevalence of tinea pedis in psoriasis, compared to atopic dermatitis and normal controls--a prospective study.

There are discrepancies in the literature regarding the prevalence of tinea pedis in psoriasis. The aim of this investigation was to conduct a cross-sectional study of the prevalence of tinea pedis in psoriasis compared to atopic dermatitis patients and normal controls. We enrolled 232 psoriatic patients, 190 atopic dermatitis patients and 202 normal controls, between the years 2010 and 2013.

Mutation in KANK2, encoding a sequestering protein for steroid receptor coactivators, causes keratoderma and woolly hair.

Background: The combination of palmoplantar keratoderma and woolly hair is uncommon and reported as part of Naxos and Carvajal syndromes, both caused by mutations in desmosomal proteins and associated with cardiomyopathy. We describe two large consanguineous families with autosomal-recessive palmoplantar keratoderma and woolly hair, without cardiomyopathy and with no mutations in any known culprit gene. The aim of this study was to find the mutated gene in these families.
