A questionnaire is considered to be internally consistent when there is a high correlation among the scores of items. This inter correlation is expressed by Cronbach's alpha. The minimum requirement for an instrument to be internally consistent is a value of 0.7016. Several other investigators have assessed the internal reliability of the DLQI, and have demonstrated Cronbach's Alpha scores of between 0.75 and 0.9217. Among patients with neurodermatitis, Cronbach's alpha was 0.889, indicating high internal reliability. ©1996-2018 MedicineNet, Inc. All rights reserved. Terms of Use.

Photography East Dane Neurodermatitis: Tips Back O Neurodermatitis can develop along with another skin condition like eczema or psoriasis, so it is best to see a skin doctor for your diagnosis. Effective treatment requires an accurate diagnosis of all of your skin conditions. The earliest descriptions of AD have referred to it as “neurodermatitis” due to the belief that the itch and scratch cycle, which results in a rash, was related to nerves and emotions. Though a lot more has been learned about immunopathogenesis of AD, recognition of itching and scratching as hallmarks of this disease remains true. Itching is often worse at night. Chronic sleep disturbance due to frequent scratching can have adverse effects on the patient and his/her immediate family members and is a source of significant stress. When subjects with AD get upset, they tend to itch even more, probably secondary to flushing of the skin due to vasodilatation induced by neurogenic peptides, followed by histamine and prostaglandin E2 (Ostlere, Cowen et al. 1995). Papules, lichenification, and eczematous lesions result from repeated skin trauma. Vesicles and erythema with excoriation of the skin are seen in acute eczema. Crusted lesions and pustules are seen in infected eczema. Allergens, irritants (wool, soap, detergents, heat and humidity with sweating), infections, and certain foods can worsen eczema, and such history helps establish the right diagnosis. Distribution of rash on the face and extensor surfaces in infants and young children, changing to mostly flexural involvement in older ages, is a classic finding of AD and one of the essential features required to make this diagnosis. Dry skin (xerosis), personal and family history of allergic diseases, palmar hyperlinearity, nipple eczema, kera-tosis pilaris, pityriasis alba, and non-specific hand or foot dermatitis are some of the other clinical manifestations of this condition (Leung and Bieber 2003; Leung, Jain et al. 2003). The impact of AD on self-esteem and social interactions of kids or adults with this condition cannot be underestimated (Lapidus and Kerr 2001).

This condition is associated with many factors, including the scratch-itch cycle, psychological stressors, and atopy. LSC is more common between ages 35 and 50 and is seen approximately twice as often in women compared to men.[3] dermatitis | infant eczema dermatitis | lichen simplex dermatitis | scalp dermatitis
