The evaluation of local oxidative/nitrosative stress in patients with pityriasis versicolor: a preliminary study.

Yeast of Malassezia, members of the microbiologic flora of the skin, cause pityriasis versicolor and have also been implicated in the pathogenesis of other superficial dermatoses. The mechanisms by which the yeast cause these dermatoses, however, are not yet clear, and there have been no studies on the interaction between fungi and keratinocytes, especially the effects of fungi on the production of reactive oxygen/nitrogen species by human keratinocytes. This is the first study we aimed to evaluate the role of oxidative/nitrosative stress in affected skin areas in patients with pityriasis versicolor.

Evaluation of local trace element status and 8-Iso-prostaglandin F2α concentrations in patients with Tinea pedis.

Background: Tinea pedis (TP) is an infection of the feet caused by fungi. The infectious diseases caused by dermatophytes are mainly related to the enzymes produced by these fungi. Up to the now, the local 8-iso-prostaglandin F2α (8-iso-PGF2α), concentration as oxidative stress biomarker and trace elements status have not been published in patients with TP.

Effect of the Syrian Civil War on Prevalence of Cutaneous Leishmaniasis in Southeastern Anatolia, Turkey.

Background: Cutaneous leishmaniasis (CL) is a vector-mediated skin disease, characterized by chronic wounds on the skin and caused by macrophages in protozoan parasites.
