The Goeckerman regimen (GR) represents a local treatment of psoriasis and includes topical dermal application of crude coal tar (containing polycyclic aromatic hydrocarbons) and exposure to UV-irradiation. The aim of the study was to evaluate contribution of GR to genotoxic risk and cellular stress in pediatric patients who represent a sensitive population subgroup. Genotoxic risk (42 patients) was evaluated by using chromosomal aberrations (CA) in peripheral lymphocytes. Cellular stress (26 patients) was assessed by using heat shock proteins (Hsp70). All indicators were determined in blood samples collected before GR and immediately after GR. Decreasing of psoriasis area and severity index (PASI) score indicated higher likelihood of GR (p < 0.001). Significantly increased CA (p < 0.001) and Hsp70 (p < 0.05) indicated higher genotoxic risk and cellular stress in sensitive pediatric patients, immediately after GR.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D011565 Psoriasis A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.

D003033 Coal Tar A by-product of the destructive distillation of coal used as a topical antieczematic. It is an antipruritic and keratoplastic agent used also in the treatment of psoriasis and other skin conditions. Occupational exposure to soots, tars, and certain mineral oils is known to be carcinogenic according to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985) (Merck Index, 11th ed).

D003131 Combined Modality Therapy The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, RADIOIMMUNOTHERAPY, chemoradiotherapy, cryochemotherapy, and SALVAGE THERAPY are seen most frequently, but their combinations with each other and surgery are also used.
