Serum Interleukin-36 in Pityriasis Rosea: A Potential Biomarker for Disease Severity.

Objective: Pityriasis rosea (PR) is a self-limiting acute rash with unclear etiology and pathogenesis. The cytokine profile of PR is an infrequently investigated field of research. The aim of this study was to assess the level of IL-36 in sera of patients with PR and its possible interrelation with disease severity.

Serum Zinc and Inflammatory Cytokines in Vitiligo.

The relation between zinc and the cytokines involved in vitiligo pathogenesis has not been studied well. We aimed to investigate the serum levels of zinc in patients with vitiligo and to assess their relation to serum interleukins (IL)-4, IL-6, and IL-17. The study included 50 patients with active vitiligo and 100 age-, sex-, and BMI-matched healthy volunteers as a control group.

Structural changes of hair shaft after application of chemical hair straighteners: Clinical and histopathological study.

Background: Chemical hair straightening becomes popular for managing frizzy hair. Keratin in hair care products can penetrate the cortex of the hair fiber improving the mechanical properties of damaged fibers and promote a surface coating that prevents or decreases water diffusion through the hair fibers. This may have beneficial effects on the hair structure; however, the side effects and safety of this treatment have not yet been completely evaluated.

Proliferative changes of epidermal cells in lesions of cutaneous leishmaniasis.

In 35 parasitologically proven zoonotic cutaneous leishmaniasis patients, the histopathological and immunohistochemical picture were studied. The haematoxylin and eosin stain, the monoclonal antibodies for T & B lymphocytes, peroxidase anti-peroxidase for P53 protein, and Feulgen staining for DNA imaging cytometry to DNA contents and S-phase (DNA synthesis of cycling cells were evaluated. The out-come results revealed that P53 and S-phase fraction and DNA content must be in mind when dealing with a human cutaneous leishmaniasis.

Ant allergy in Benha District Qualyobia Governorate, Egypt.

Individuals from the suburb of Benha City and some adjacent villages were presented with various degrees of skin allergy. In addition, chiildren who spend the night (sleep) on the floor suffered generalized lymphadenopathy, with or without fever. The patients were successfully treated with carbolic acid (1:25).

Eucalyptus globulus (camphor oil) in the treatment of human demodicidosis.

Demodex folliculorum (Follicular or Demodicid mite) is a zoonotic obligatory parasite with clinical manifestations range from normal infestation to complicated ones. Treatment of human facial demodicidosis with freshly prepared camphor oil with or without glycerol dilutions gave complete cure with concentrations of 100%, 75%. and 50%.
