Selection Of Therapy For Acne Vulgaris

The widespread use of long-term antibiotics to treat acne and rosacea has resulted in increased Propionibacterium acnes resistance to antibiotics. Although resistance may decrease treatment effectiveness in some cases, it also is clear that antimicrobial activity is not the only role antibiotics play in acne management.

The anti-inflammatory activity of antibiotics contributes to antipropionibacterial efficacy. In addition, the use of benzoyl peroxide (BPO) in combination with antibiotics to reduce resistant populations of propionibacteria is widely advocated, as P acnes has not developed resistance to it. P acnes now is known to form biofilms, which are bacterial communities that live encased in a glycocalyx polymer that aids in adherence to surfaces, thereby delaying antibiotic penetration.

In addition to drug resistance, patient compliance with acne treatment is an important issue. Because compliance is a function of tolerability and convenience, new moisturizing noncomedogenic vehicles and fixed BPO-antibiotic combinations can be expected to improve compliance. Better efficacy has been noted with BPO-antibiotic combination therapy.

And this Japanese-inspired bathroom remodel in by Weston Miles Architects is a prime example. These before photos show a pleasant enough bathroom with bright color and functional traditional cabinetry, though a small sink space, not-so eco-friendly materials, and dim lighting. This after photo shows an incredible remodel that makes use of traditional materials in a modern aesthetic. The focal point is this Japanese soaking tub that the client wanted, and the room grew around that. The room has been opened up for a step-in shower next to the tub, its warm lichen-green balanced against the natural wood of the tub and wood trim. This beautiful remodel exemplifie...

Prevalence Of And Associated Factors For Dry Eye In A Spanish adult population

To estimate the prevalence of dry eye and to investigate its relationship with lifestyle and systemic factors in a general adult population in north-western Spain. METHODS: A dry eye questionnaire was administered and objective tests were performed in 654 individuals [mean age (Standard deviation): 63.6 (14.4) years, range: 40-96, 37.2% males]. Subjects were considered symptomatic when one or more of the symptoms of the questionnaire were present often or all the time. Schirmer test or= 3 and fluorescein staining >or= 1 were considered indicative of signs. Dry eye was defined as the simultaneous presence of symptoms and at least one sign. A design based analysis was performed and all calculations were weighted to give unbiased estimates. RESULTS: Dry eye prevalence was 11.0% (95%confidence interval [CI] 8.6-13.3). Dry eye was found to be more frequent in women (11.9%, 95%CI 8.8-15.1) than in men (9.0%, 95%CI 5.3-12.6), and was significantly associated with aging (p autoimmune diseas...

Enhanced Skin Blood Flow And Sensitivity to Noxious Heat Stimuliin papulopustular rosacea

Although patients with rosacea often complain of increased skin sensitivity, there has been no quantitative sensory testing of this phenomenon. Furthermore, cutaneous blood flow in these patients has not been assessed using state-of-the-art laser Doppler imaging (LDI). OBJECTIVES: To assess heat pain thresholds and skin blood flow using quantitative thermal sensory testing and LDI in patients with untreated rosacea . METHODS: Of the total 24 subjects enrolled, 8 had papulopustular rosacea (PPR), 8 had erythematotelangiectatic rosacea (ETR) and 8 were control subjects. Subjective burning perception, heat pain threshold, skin blood flow, and skin temperature was assessed in all subjects. In the ETR and PPR groups, two areas were compared: affected and nonaffected. RESULTS: Heat pain thresholds of areas affected by rosacea were lower than those of nonaffected areas. In addition, subjective burning perception was increased in rosacea patients when compared with control subjects. Altho...
