Öğe Comparison of two surgical approaches for treating vitiligo(Blackwell Publishing Ltd, 2002) Özdemir, M; Çetinkale, O; Wolf, R; Kotogyan, A; Mat, C; Tüzün, B; Tüzün, YBackground Surgical techniques have recently been introduced for patients with vitiligo. Randomized controlled trials have not been performed. Aim To compare the efficacy and side-effects of two surgical methods (suction blister vs. thin split-thickness graft technique) for the treatment of vitillgo. Methods Three suction blisters, approximately 0.8 cm in diameter, made with a special tool attached to a vacuum extractor, which were converted to erosions by removal of the roofs of the bullae, and one round erosion of approximately the same diameter, made using a silver knife, were created. One roof of a blister and two cutaneous thin split-thickness grafts taken from the gluteal region were transferred onto recipient vitiliginous areas; one was left alone. The results were evaluated by one non-blind and two blind observers bimonthly during the 3-month follow-up period. Results Repigmentation rates were 25-65% in the suction blister technique and 90% in the thin split-thickness graft technique (P < 0.001). Conclusions The thin split-thickness graft technique is superior to the suction blister technique in treating vitiligo.Öğe Familial erythromelanosis follicularis and chromosomal instability(European Acad Dermatology & Venereology, 2001) Tüzün, Y; Wolf, R; Tüzün, B; Özdemir, M; Demirkesen, C; Deviren, A; Kotogyan, AWe report a 17-year-old male patient with erythromelanosis follicularis faciei et colli (EFFC), oral leucokeratosis and diabetes mellitus without islet cell antibody. His sister also had minimal findings of EFFC and minimal follicular papules on her shoulders and extensor surfaces of the arms. The father had only fine follicular papules, but no erythromelanosis. Skin and mucous membrane lesions of the proband were investigated histopathologically. Interestingly, in peripheral lymphocyte cultures of the family members, chromosomal breakage was not observed spontaneously, but it was seen with nitrogen mustard, although this disease may be of autosomal recessive inheritance. Thus, we suggest that EFFC may be a poly-aetiological disorder (i.e. familial and environmental) and might be considered one of the chromosomal instability syndromes.
