Rosacea

Complete nucleotide sequences have been determined for atp6 from Suillus luteus and cox3 from Suillus sinuspaulianus (Boletales, Hymenomycetes, Basidiomycota), which code for ATPase subunit 6 and cytochrome oxidase subunit 3, respectively. These sequences were used to design PCR primers for the amplification of partial atp6 and cox3 sequences from other members of the Boletales and outgroup taxa. In atp6 and cox3 from Russula rosacea, one of the outgroup taxa, we observed a number of in-frame TGA(trp) codons, which imply a Neurospora crassa-type mitochondrial code in R. rosacea and possibly in basidiomycetes in general. Interestingly, however, most basidiomycetes other than R. rosacea appear to strongly prefer the TGG(trp) codon, which is unusual, given the strong A + T bias in fungal mitochondrial genomes. Pairwise comparisons were performed between atp6 sequences from increasingly divergent fungal lineages, and results show that all three codon positions become saturated in substitu...

Adv Ther. 2009 Jun 23; Schechter BA, Katz RS, Friedman LSINTRODUCTION: This study was designed to compare the efficacy of cyclosporine ophthalmic emulsion 0.05% with an artificial tear solution for the treatment of rosacea-associated eyelid and corneal pathology. METHODS: Double-masked, randomized, 3-month clinical trial of 37 patients with rosacea-associated eyelid and corneal changes (defined as lid margin telangiectasia, meibomian gland inspissation, and/or fullness of the lid margin). All findings were standardized and compared to photographs for grading. RESULTS: There was a statistically significant increase in Schirmer (with anesthesia) scores of 2.7+/-2.2 mm after 3 months of treatment in the topical cyclosporine group (P

Dermatol Online J. 2009; 15(3): 10Ul Bari A, Ejaz ACutaneous leishmaniasis is known for its wide clinical spectrum. The nose is one of the usual sites where the disease can present in many forms, such as psoriasiform plaques, furunculoid nodules, lupoid plaques, and erysipeloid or mucocutaneous types. We present a new morphology, i.e. rhinophyma-like plaque in an elderly male patient who presented with a large infiltrated plaque involving his nose and the adjoining area of his upper lip. It appeared to be rhinophyma of the nose but was diagnosed as cutaneous leishmaniasis after the demonstration of leishmania parasites in a skin smear preparation; he was treated satisfactorily with antimonials.

Am J Dermatopathol. 2009 Jul; 31(5): 423-6Sachdeva MP, Goldblum JR, Rubin BP, Billings SDPleomorphic lipomas are benign tumors that most commonly present as subcutaneous masses in the head and neck, shoulder, or back region of middle-aged to elderly men. They are related to spindle cell lipomas based on shared cytogenetic aberrations and histologic features. When little or no fat is present, the diagnosis can be challenging. A review of 38 pleomorphic lipomas seen in consultation revealed 7 cases in which fat was present in reduced (

J Drugs Dermatol. 2009 May; 8(5): 459-62Ortiz A, Elkeeb L, Truitt A, Hindiyeh R, Aquino L, Tran M, Weinstein GBACKGROUND: Current treatments for acne rosacea are often associated with unsatisfactory outcomes and adverse effects. OBJECTIVE: To determine the efficacy and tolerability of a new moisturizing lotion for improving the clinical signs and symptoms of mild-to-moderate acne rosacea. METHODS: In a 12-week, open-label study, a moisturizing lotion containing furfuryl tetrahydropyranyladenine as PRK124 (0.125%, Pyratine-XR, Senetek PLC, Napa, CA) was applied twice daily to subjects with mild-to-moderate rosacea. Improvement in the appearances of erythema and papules were assessed by the treating physician. Skin barrier function was measured by transepidmal water loss after treatment. Tolerability and cosmetic outcome were evaluated by patients. RESULTS: Twenty-one participants completed the study. Overall clinical improvement was observed in 80% of subjects, with most showing mild-t...

Patients with rosacea and red facial skin often show sensitivity to skin care products which can exacerbate inflammation and subjective irritation. Besides pharmacologic management, special skin care is prudent to avoid cosmetically induced irritation and address cosmetic concerns. Appropriate skin care should provide gentle cleansing, UVA/UVB protection, effective moisturization, and concealing pigments to neutralize the appearance of redness. AIMS: To evaluate skin compatibility and efficacy of a skin care regimen containing licochalcone A (Lic A), an anti-irritant from the licorice plant Glycyrrhiza inflata, for subjects with mild to moderate facial redness. PATIENTS/METHODS: Sixty-two patients with mild to moderate red facial skin used a four-product skin care regimen for 8 weeks. Clinical assessments of erythema and subjective irritation, cross-polarized photography, and self-assessment questionnaires were completed at baseline, and after 4 and 8 weeks of use. A quality of life ...

Rosacea fulminans (also known as pyoderma faciale) has been reported to occur in association with Crohn's disease. It is still unclear whether the papulopustules and confluent nodules of rosacea fulminans represent a manifestation of mucocutaneous Crohn's disease or whether this association is a mere coincidence. A 46-year-old woman presented with the spontaneous outbreak of rosacea fulminans and pyostomatitis/pyovulvitis. Complete remission of the mucocutaneous symptoms was achieved with 2 months combination therapy with methylprednisolone, isotretinoin and dapsone. The patient's Crohn's disease, already diagnosed for 3 years, did not flare during this period.
