Rosacea

To determine tear lactoferrin levels in patients with chronic diffuse meibomitis associated with acne rosacea and to investigate their role in the development and perpetuation of some inflammatory ocular surface complications. METHODS: In this non-randomized, controlled trial performed in a tertiary care center, eight patients with biopsy-proven acne rosacea and blepharitis , and ten patients with seborrheic blepharitis not associated with acne rosacea formed the study groups and ten normal patients were used as controls. Schirmer I test results, tear break-up time and radial immunodiffusion (Lactoplate) tests on tear samples of the three groups were compared. RESULTS: Compared to controls, tear lactoferrin concentrations were lower in both the acne rosacea and seborrheic blepharitis groups. However, this decrease was significant in only the seborrheic blepharitis group (p = 0.026). One patient in the acne rosacea group, with the lowest measurement, developed bacterial keratitis. CONC...

To correlate tear fluorescein clearance with interleukin-1alpha (IL-1alpha) concentration and gelatinase B (matrix metalloproteinase [MMP]-9) activity in the tear fluid of patients with ocular rosacea and normal control subjects. METHODS: Gelatinase activity was evaluated by gelatin zymography in tear fluid obtained from 13 patients with ocular rosacea (including 1 patient with recurrent epithelial erosion, 2 with recurrent peripheral corneal infiltrates and vascularization, and 2 patients with epithelial basement membrane dystrophy) and 13 normal subjects with normal aqueous tear production and no irritation symptoms. Tear fluorescein clearance was evaluated by measuring fluorescence in tear fluid collected from the inferior meniscus 15 minutes after instillation of 5 microl of 2% Na-fluorescein with a CytoFluor II fluorometer. Pro-MMP-9 and IL-1alpha concentrations in the tear fluid were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: Compared with normal control sub...

There is increasing evidence for systemic effects of gastric H. pylori infection which may result in extragastrointestinal disorders. This review summarizes the available medical literature up to September 1999, identified through a MEDLINE research including own studies, regarding H. pylori and skin diseases. Due to current knowledge best evidence for a potential link of H. pylori infection exists for chronic urticaria although the data are still conflicting. Thus, the search for H. pylori should be included in the diagnostic management of chronic urticaria. With regard to other skin diseases such as rosacea , hereditary or acquired angioedema due to C1-esterase inhibitor deficiency, systemic sclerosis, Schönlein-Henoch purpura, Sjögren's syndrome, sweet's syndrome, and atopic dermatitis only single of few cases have been reported so far. Thus, we clearly need further randomized, double-blind and placebo-controlled studies including adequate diagnostic schedules, sufficient er...

Rosacea is a common condition of unknown etiology usually accompanied by gastrointestinal symptoms and favorably responding to the treatment with antibiotics. This study was designed to examine the prevalence of gastric Helicobacter pylori (Hp) infection verified by 13C-UTB-test, CLO, Hp culture and serology (IgG) in patients with rosacea. Gastroduodenoscopy was combined with pentagastrin secretory test and antral and fundic biopsy samples were taken for histological evaluation (the Sydney system). Blood samples were also taken for the determination of plasma gastrin using RIA and plasma interleukin (IL)-8 and tumor necrosis factor alpha (TNFalpha) using ELISA. This study was performed in 60 patients, 31-72 year old, with visible papules and pustules associated with erythema and flushing on the face and on 60 age- and gender-matched patients without any skin diseases but with similar as in rosacea gastrointestinal symptoms but without endoscopic changes in gastroduodenal mucosa (non-...

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.
