Instrument For Acne Rosacea

No rosacea-specific quality-of-life (QOL) instrument exists.

OBJECTIVE:
We sought to develop a validated, reliable rosacea-specific instrument.

METHODS:
From 6 in-depth interviews, we composed 21 rosacea-specific items. These items and Skindex-29 were administered in a validation cohort (n = 59). Internal consistency reliability and reproducibility were measured with Cronbach's coefficient alpha and intraclass correlation coefficient, respectively.

Responsiveness was assessed comparing baseline with 4- to 6-month responses. Construct validity was assessed with principal axes factor analyses. Discriminant validity was examined with an additional 38 patients comparing differences in responsiveness between the rosacea-specific QOL instrument and Skindex.

RESULTS:
Reliability was high (Cronbach's alpha: 0.82-0.97, intraclass correlation coefficient: 0.70-0.95). The rosacea-specific QOL instrument showed preliminary responsiveness for patients with improved disease

Azelaic acid in the treatment of papulopustular rosacea

To evaluate the clinical efficacy of topical 20% azelaic acid cream and 15% azelaic acid gel compared with their respective vehicles and metronidazole gel in the treatment of papulopustular rosacea . DATA SOURCES: Electronic searches of MEDLINE, EMBASE, BIOSIS, and SciSearch through July or August 2004 and the Cochrane Central Register of Controlled Trials through 2004 (issue 3). We performed hand searches of reference lists, conference proceedings, and clinical trial databases. Experts in rosacea and azelaic acid were contacted. STUDY SELECTION: Randomized controlled trials involving topical azelaic acid (cream or gel) for the treatment of rosacea compared with placebo or other topical treatments. Two authors independently examined the studies identified by the searches. Ten studies were identified, of which 5 were included (873 patients). DATA EXTRACTION: Two authors independently extracted data from the included studies, then jointly assessed methodological quality using a quality a...

Management of benign skin lesions commonly affecting the face: actinic keratosis, seborrheic keratosis, and rosacea.

Curr Opin Otolaryngol Head Neck Surg. 2009 May 21; Brodsky JPURPOSE OF REVIEW: Patients commonly present to the otolaryngologist for management of benign facial lesions. It is important to be able to both recognize these lesions and offer patients the most effective therapies currently available. Advances in the understanding and management of three of the more common benign skin lesions affecting the face will be addressed in this review, with a particular emphasis on the most current therapeutic options for each lesion. RECENT FINDINGS: Actinic keratosis can now be treated with photodynamic therapy or with many topical agents, as alternatives to traditional surgical techniques. Seborrheic keratosis, as well as actinic keratosis and rosacea, are now often treated with laser therapy. In addition, rosacea management now includes nonantimicrobial topical agents, such as azelaic acid, and a wider armamentarium of systemic agents. SUMMARY: An understanding of these options will allow the ...
