Some laser irradiation parameters such as wavelength, fluence, pulse duration, and spot sizehavebeen shown to influence the damage of any target inside the skin, however, the role of some patients’ factors such as hair growth cycle is still under debate. Objective. To determine the association of treatment interval and laser treatment outcome. Methods. In a retrospective chart review of 176 patients undergoing laser-assisted hair removal with a diode laser 24 patients were selected. All accepted to cease the therapy, and be followed-up for 5 months. At the end of the study the patients were questioned about the efficacy of the treatment as well as the adverse effects. Hair counting was also performed. The adverse effects (pain, blister or erosion, hyperpigmentation, hypopigmentation, and folliculitis) were questioned during the follow-up period. Results. The mean hair reduction was 78.1% , 45.8% , and 28.7% in45,60,and90-dayintervalgroups,respectively(P < 0.0001). Conclusion. The treatment interval was related to the treatment outcome in our study.展开更多

It is a chronic disease which causes severe disfigurement, and so may significantly affect a patient’s quality of life. This study was designed to evaluate the illness perception and quality of life in patients with vitiligo. Patients and methods. A questionnaireconsistingof25questionsonthecauses,timeline, consequences, and control of disease was given to 80 patients with vitiligo attending a private skin clinic in Tehran, Iran, in 1999. The roles of age, sex, duration of disease, education, extent of disease, and family history of vitiligo were assessed. Results. Eighty patients (22 males and 57 females, one not mentioned), with a mean age of 30 years (SD=11 years) and a disease duration of 7.1 years (SD=7.8 years), completed the questionnaire; 62.5%of the patients believed that stress played a role in their disease; 31.3%believed that their genetic background played a role in their disease, more so in patients with a positive family history of vitiligo. Almost one-half of patients believed that their illness had major consequences on their lives. One-half of patients believed that their illness was likelytobepermanentratherthantemporary,moresoinpatients with a longer duration of disease and a higher level of education. Only 60%of patients considered that their treatments were effective. Conclusion. Vitiligo may considerably affect various aspects of patients’lives. The knowledge of patients about the causes and course of their disease is limited.展开更多
