T HE Medical Research Council's investigation into pityriasis rosea in 1959 has already been published (Proc. roy. Soc. Med., 55, 556). This second investigation, based on a very simple questionnaire, has produced some additional information, but has not altogether solved the question put, namely "What is the cause of this disease?" Much interest was shown. In 1964, 180 observers notified 531 c...

AIM: To report a case of a patient with pityriasis lichenoides et varioliformis acuta (PLEVA) who developed a conjunctival inflammatory nodule. CASE REPORT: a 13-year-old boy with a diffuse papulovesicular rash diagnosed as PLEVA presented to our clinic complaining of irritation in his right eye. Slitlamp examination revealed a conjunctival inflammatory nodule. His symptoms resolved under topic...

IL: interleukin PRP: pityriasis rubra pilaris TNF: tumor necrosis factor INTRODUCTION Pityriasis rubra pilaris (PRP) is a heterogeneous inflammatory skin disease characterized by follicular papules, orange palmoplantar keratoderma, and erythematous scaly patches with islands of skin sparing. Type II PRP is a rare, severe, chronic form of PRP presenting atypical features including long disease d...

Background: No clinical clues to differentiate between extrinsic atopic dermatitis (eAD) and intrinsic atopic dermatitis (iAD). Aim: To compare presence of Pityriasis Alba (PA) in patients with extrinsic and intrinsic type of AD. Subjects & Methods: IL-4 and Ig-E were measured in 85 Patients’ serum with enzyme linked immune sorbent assay (ELISA). Forty three patients with (eAD) (group I) (n=43)...

The differential diagnosis of erythemato-squamous diseases is a difficult problem in dermatology. Artificial Neural Network (ANN) classifies the given samples when trained and nearly 98 % classification accuracy is achieved. Generalized Feed Forward Neural Network (FFNN) can solve the multivariable classification problem of determination of skin disease. ANN approach is studied to determine the...

    Pityriasis Alba is an eruptive skin disorder which occurs as dry hypopigmented , scaly patches appears mainly in sun expose areas of skin, usually in children and young adolescents. Complete cure occurs within few years even without treatment. Few trace elements play essential roles as cofactors in pigmentary process of the skin. In this study by determination of zinc and copper levels in...
