Rosacea is a common skin disease with a high impact on quality of life. Characterized by erythema, edema, burning pain, immune infiltration, and facial skin fibrosis, rosacea has all the characteristics of neurogenic inflammation, a condition induced by sensory nerves via antidromically released neuromediators. To investigate the hypothesis of a central role of neural interactions in the pathop...

Rosacea is a common facial dermatosis that is seldom biopsied; thus, histological aspects have not been well described. Biopsies are generally performed in the presence of atypical symptoms (e.g. granulomas). Differential diagnosis with sarcoidosis, lupus miliaris or lupus erythematosus is another indication for biopsy. There are few published studies addressing the microscopic aspects of rosac...

Dietary change may play a role in the therapy of rosacea. Certain foods and beverages may act as "triggers" for rosacea exacerbations. These may be divided into heat-related, alcohol-related, capsaicin-related, and cinnamaldehyde-related. One potential pathogenic mechanism may be via the activation of transient receptor potential cation channels, which result in neurogenic vasodilatation. Furth...

PURPOSE To describe a case of severe rosacea with ocular involvement. CASE REPORT A 28-year-old female patient presented with extensive facial and ocular eruptions. She had a history of treatment with oral prednisolone due to the clinical diagnosis of lupus erythematosus (LE), which had resulted in transient improvement of the lesions, but was followed by exacerbation of the lesions. With the...

Rosacea is a common chronic inflammatory cutaneous disease of unknown etiology, characterized by remissions and exacerbations, presenting with centrofacial erythema and telangiectasias. It affects mainly adults around the age of 30 years and classically predominates in females. The pathophysiology of rosacea has not yet been fully understood. Risk factors are positive family history, very light...

early they were noticed and referred to their true origin. It is true that some gynaecologists have considered the chloasma identical with pityriasis versicolor ; but this error is too striking, and the distinction between the two affections is too easily and too generally acknowledged, to render it neecssary to dwell upon their differential symptoms. My object is to draw attention to some othe...

BACKGROUND Recent studies highlighting the psychological benefits of medical treatment for dermatological skin conditions have demonstrated a clear role for medical therapy in psychological health. Skin conditions, particularly those that are overtly visible, such as those located on the face, neck, and hands, often have a profound effect on the daily functioning of those affected. The literatu...

Skin problems are common during pregnancy, but accurate diagnosis can be difficult. Skin changes in pregnancy can be broadly divided into physiological (box 1), specific dermatoses of pregnancy, and other common skin diseases in pregnancy. In our experience of pregnancy skin clinics, approximately 50% of women present with an exacerbation of a common inflammatory skin disease (for example, ecze...

INTRODUCTION The addition of hydrophobically modified polymers (HMPs) to cleansers that contain surfactants can create polymer-surfactant complexes that are less irritating to the skin than commercially available mild cleansers. Our objective was to compare the tolerability and efficacy of a test foaming liquid facial cleanser containing HMPs with a commercial liquid nonfoaming facial cleanser ...

IMPORTANCE To our knowledge, this is the first study on rosacea to formally define genetic and environmental contributions. OBJECTIVES To study a cohort of identical and fraternal twins to determine whether genetic factors contribute to rosacea development and, if genetic factors are present, quantitatively estimate the genetic contribution, as well as to identify environmental factors that c...
