Rosacea is a common and chronic inflammatory cutaneous disease with unknown etiology. The pathophysiology of rosacea is still poorly understood. Epidemiological studies indicate a genetic component, but a rosacea gene has not been detected yet. Recent molecular studies propose that an altered innate immune response is involved in the pathogenesis of the(More)
Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy, is a benign proliferative disorder of histiocytes with an unknown etiology. It is a rare disease characterized by overproduction and accumulation of histiocytes within lymph node sinuses and many other extranodal sites, including skin, oral and nasal cavities, respiratory(More)
BACKGROUND Vitiligo is a chronic, common disease of unknown etiology, and oxidative stress is suggested to have a role in its etiopathogenesis. OBJECTIVE Advanced oxidation protein products (AOPPs), prooxidant-antioxidant balance (PAB), and ferric-reducing antioxidant power (FRAP) were evaluated regarding their role in the pathogenesis of vitiligo as well(More)
PURPOSE To compare the topographic and biomechanical properties of corneas in the eyes of patients with ocular rosacea (OR) with those of healthy individuals. METHODS Thirty-four healthy individuals (control group) and 34 patients with OR (study group) were evaluated in this study. Topographic measurements including keratometry values, irregularity, and(More)
Purpose. We report the effect of isotretinoin on corneal topography, corneal thickness, and biomechanical parameters in patients with acne vulgaris. Method. Fifty-four eyes of 54 patients who received oral isotretinoin for treatment of acne vulgaris were evaluated. All patients underwent a corneal topographical evaluation with a Scheimpflug camera combined(More)
PURPOSE To compare the topographic and biomechanical properties of corneas in eyes of patients with ichthyosis vulgaris (IV) and eyes of healthy individuals. METHODS Thirty healthy individuals (control group) and 30 patients with IV (study group) were enrolled in this prospective study. Topographic measurements, including keratometry values, irregularity,(More)
Anogenital malignancies and premalignancies are an important personal/public health problem due to their effects on individuals' physical, mental, and sexual health. Also, due to their etiological association with human papillomavirus (HPV) infection, anogenital malignancies and premalignancies constitute an immense public health burden. In addition to HPV(More)
Helicobacter pylori is a Gram-negative bacterium that has been linked to peptic ulcer disease, gastric lymphoma, and gastric carcinoma. Apart from its well-demonstrated role in gastroduodenal diseases, some authors have suggested a potential role of Helicobacter pylori infection in several extra-intestinal pathologies including haematological,(More)
