[The estimation of atopic dermatitis in infants and small children in general practitioner's practice--own observations].

Purpose: The purpose of the work is to estimate the frequency of atopic dermatitis in general practitioner's practice.

Material And Methods: The study has been conducted on the basis of the retrospective analysis of medical documentation of individual history of disease among children born in 2005-2008 treated in an outpatient clinic of the Polish Mother's Memorial Hospital, Lodz, Poland.

Results: Infants and small children suffering from atopic dermatitis are abig group (31.

[The role of Langerhans cells in the skin immune system].

Langerhans cells (LC) are members of the dendritic cells family, residing in the basal and suprabasal layers of the epidermis and in the epithelia of the respiratory, digestive and urogenital tracts. They specialize in antigen presentation and belong to the skin immune system (SIS). LC acquire antigens in peripheral tissues, transport them to regional lymph nodes, present to naive T cells and initiate adaptive immune response.

Do Langerhans cells play a role in vulvar epithelium resistance to squamous cell carcinoma?

Introduction: Langerhans cells (LCs) are a very important part of the skin immune system.

Materials And Methods: Skin biopsies taken from 13 women after the removal of vulvar squamous cell carcinoma (SCC) who had not been treated earlier for any vulvar diseases were investigated. The control group consisted of 12 women who underwent a plastic surgical operation of the vulva region.

Langerhans cells in vulvar lichen sclerosus and vulvar squamous cell carcinoma.

Introduction: Langerhans cells (LCs), specializing in antigen presentation, are a very important part of the skin immune system (SIS).

Materials And Methods: Skin biopsies from 22 women with vulvar lichen sclerosus (LS): 15 patients with early and 7 with the late stage of the disease, were evaluated. Five women with vulvar squamous cell carcinoma (SCC) were also examined.

Influence of systemic photochemotherapy on regulatory T cells and selected cytokine production in psoriatic patients: a pilot study.

Background: Psoriasis is a chronic autoimmune inflammatory disease of the skin with strong genetic and environmental risk factors and is regarded as a Th1 cell-type disease. The aim of our study was to evaluate the effect of one-month PUVA (Psoralen Ultraviolet A) therapy on a regulatory T-cell subpopulation (CD4+CD25+) and the production of some cytokines.

Material/methods: The study was performed on the group of 12 patients with severe psoriasis.
