This may provide a closer understanding of the pathogenesis of this disease entity. Hopefully, this insight can set the route for newer therapeutic approaches. Background Vitiligo is an acquired dyschromia of the skin, in which there is a loss of epidermal melanocytes. The prevalence of vitiligo is ~ 0.1–2% worldwide. The exact pathogenesis of vitiligo remains elusive and is likely multifactorial. S100 proteins are localized in the cytoplasm and nucleus of a wide range of cells and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. Patients and methods This case–control study was carried out on 40 patients with vitiligo and 40 age-matched and sex-matched healthy volunteers as a control group. All participants were subjected to a full history taking, general examination, local examination with determination of site of the lesions, assessment of vitiligo activity and severity, and laboratory investigation for quantitative measurement of S100B protein in vitiligo serum. Results There was a highly significant difference between cases and controls regarding the mean S100B level. There was a significant difference between cases with elevated S100B and normal level of S100B regarding vitiligo area scoring index score. There was a significant positive correlation between S100B and vitiligo disease activity score. Conclusion S100 protein is elevated in patients with vitiligo more than healthy population. This may be owing to that S100 protein is involved in vitiligo pathogenesis through affecting Ca homeostasis and activation of proinflammatory cascade with release of interleukin-1B and interleukin-6.

The aim of the study is to investigate existing proper behavior instructions in hotels, beaches, and archaeological sites in Alexandria Governorate show the frequent tourist misbehavior and activate the role of tourism and hotel stakeholders in avoiding these behaviors; highlight the domestic tourism challenges and eventually, present recommendations on improving services provided to the tourists in Alex. A quantitative survey with a questionnaire was targeted domestic tourists who had previously spent their holidays in Alexandria Governorate and stayed in its hotels. The sample consisted of 354 participants. Data revealed the inadequate of existing proper behavior instructions and the weak role of tourism and hospitality stakeholders to increase awareness of domestic tourists towards proper behaviors on tourist beaches, in hotels, and archeological places. The study also found out occurrences frequencies of improper behaviors of the domestic tourists that merit the most immediate attention before its exacerbation. The study also revealed challenges related to tourism of beaches as inadequate services and the absence of many tourist facilities. The study recommends firstly, developing the infrastructure services that are right for the customers' need; setting ground rules for visitor behavior to crack down on tourist misbehaving tourists, and finally, encouraging and supporting positive behaviors among domestic tourists through announcing periodic competitions among Egyptian visitors in touristic places and choosing the perfect local tourist.
