p63 expression in randomized odontogenic cysts

To find out the immunohistochemical assessment of p63 expression in odontogenic cysts based on the differences among their clinical behaviors. This study was carried out on 34 archival paraffin-embedded specimens of odontogenic cysts. We obtained the specimens from the Pathology Department of Babol University of Medical Sciences, Babol, Iran from March 2003 to February 2008. The specimens comprised 12 dentigerous cysts, 9 radicular cysts, and 13 keratocystic odontogenic tumors [KCOTs]. The immunohistochemical technique was performed using the Envision system for evaluation of p63 expression. The KCOT revealed the highest p63 expression and the differences between the 3 groups was statistically significant. P63 expression might be helpful when identifying cyst types with more aggressive and invasive phenotype

Treatment of vitiligo with blister grafting technique

Surgical treatments of vitiligo are punch grafting, blister grafting, flip-top transplantation, split skin grafting, etc aiming at rebuilding of melanocytic population in those patients who do not respond to medical treatment The objective of this study was determination of efficacy of blister grafting technique in the treatment of vitiligo. This study was done on 10 patients with vitiligo of face and /or distal extremities who had received different medical treatments including PUVA and had not responded, and their diseases were stable. Blister in recipient site was created by cryotherapy and in donor site by using vacuum device. Then donor site blister was transferred to the recipient site and bath sites were covered by dressing. 10 patients [8 females and 2 males] with mean age of 31.2 +/- 11.4 years entered the study. After 1-6 weeks, first signs of repigmentation were observed and after 4 months complete repigmentation occured in 7 patients [70%] In two patients, a repigmentation of more than 50% was observed while in one patient no pigmentation was seen which was related to errors in surgical technique. Blister grafting surgery in limited patches of vitiligo which have not responded to medical treatments gives excellent results of prolonged repigmentation without any scar formation

[ assessment of the awareness of senior students about the effects of sunlight on the skin and necessity and methods of sun protection]

Nearly ninety percent [90%] of skin cancers occur in sun exposed areas. In this study the awareness of senior students of Mashhad University [Ferdowsi] about the effects of sunlight on the skin plus necessity and methods of sun protection is evaluated. In this descriptive study in 2004 at Mashhad University [Ferdowsi], 802 senior students of 9 majors enrolled. This study was approved by the local committee of Medical Ethics. The standard questionnaires including 24 questions distributed among students. The students divided into groups according to their score in the 24 awareness questions: weak [score
