Rosacea is a chronic skin condition characterized by persistent central facial erythema. To explore the burden of illness of rosacea in US adults, a cross-sectional web-based survey was conducted. Participants answered questions on sociodemographics, clinical characteristics, bothersome symptoms, coping and avoidance behaviors, self-perceptions, and health care resource utilization, and completed 2 quality of life instruments, the 21-item rosacea-specific quality of life questionnaire (RosaQoL) and the 36-item Short Form Health Survey (SF-36). This paper reports the data from the 409 respondents with erythematotelangiectatic rosacea (ETR), analyzed by erythema severity. Mean age was 53.1 years; mild, moderate, or severe erythema was reported by 63.6%, 32.0%, and 4.4% of participants, respectively. Blushing/flushing and bumps/pustules were the most bothersome symptoms across severity subgroups. Participants in all subgroups coped with rosacea by applying make-up and managing their stress and anxiety, and tried to prevent rosacea flares by avoiding sun exposure, specific skin care products, and other triggers. Self-perceptions differed by severity subgroup: satisfaction with facial appearance significantly decreased, and worrying about how people will react and feelings of unattractiveness to others significantly increased, with greater erythema severity (all P less than 0.01). Treatment or assessment of rosacea was sought by 20% of participants in the past 3 months, most commonly from a dermatologist. Metronidazole was the most frequently prescribed topical product across severity subgroups, whereas doxycycline and other oral antibiotics were prescribed most frequently in the severe erythema subgroup. RosaQoL emotional domain scores increased with erythema severity (P equals 0.0035), but none of the SF-36 domain scores differed significantly by erythema severity. These results demonstrate that rosacea is associated with a substantial burden of illness that spans all levels of erythema severity in patients with ETR. Feelings of unattractiveness and the adverse impact of rosacea on emotional quality of life increased with erythema severity. J Drugs Dermatol. 2018;17(2):150-158.

Intense pulsed light (IPL) is a broad spectrum incoherent light which is produced by high-output xenon lamp. Since the invention of the first-generation IPL in 1994, IPL technology has been developing rapidly and extensively utilized in multiple fields relevant to dermatology across the world. In 2004, the fourth-generation IPL system was introduced with the optimal pulse technology (OPT) and has soon been used for cosmetic purposes all over the world. In 2002, Dr. Toyos found that the meibomian gland dysfunction (MGD) and dye eye disease (DED)symptoms of the rosacea patients who received IPL treatment have been improving significantly, therefore he started to explore the application of IPL system to treatment of dry eye disease. Several recent clinical studies have demonstrated the therapeutic potential of IPL for improving the symptoms and signs of MGD and DED. However, the published data of IPL treatment for MGD and DED is limited, the mechanism of IPL treatment for MGD and DED remained unclear and more relevant researches needed to be done in the future. This article discusses the clinical application history and general mechanism of IPL, and introduces the treatment of IPL for MGD and DED.(Chin J Ophthalmol, 2018, 54: 140-143).

The overexpression and increased activity of the serine protease Kallikrein 5 (KLK5) is characteristic of inflammatory skin diseases such as Rosacea. The use of inhibitors of this enzyme-such as 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF·HCl) or the anti-human recombinant Kallikrein 5 (anti-KLK5) antibody-in the treatment of the disease has been limited due to their low bioavailability, for which their immobilization in drug delivery agents can contribute to making serine protease inhibitors clinically useful. In this work, we synthesized gold nanoparticles (GNP) coated with a mixture of hydroxyl- and carboxyl-terminated thiolates (GNP.OH/COOH), whose carboxyl groups were used to further functionalize the nanoparticles with the serine protease inhibitor AEBSF·HCl either electrostatically or covalently (GNP.COOH AEBSF and GNP.AEBSF, respectively), or with the anti-KLK5 antibody (GNP.antiKLK5). The synthesized and functionalized GNP were highly water-soluble, and they were extensively characterized using UV-vis absorption spectroscopy, Transmission Electron Microscopy (TEM), Dynamic Light Scattering (DLS), and Thermogravimetric Analysis (TGA). GNP.OH/COOH and their subsequent functionalizations effectively inhibited KLK5 in vitro. Internalization of fluorophore-coated GNP.OH/COOH in human keratinocytes (HaCaT cells) was proven using confocal fluorescence microscopy. Cell viability assays revealed that the cytotoxicity of free AEBSF is importantly decreased when it is incorporated in the nanoparticles, either ionically (GNP.COOH AEBSF) or, most importantly, covalently (GNP.AEBSF). The functionalized nanoparticles GNP.AEBSF and GNP.antiKLK5 inhibited intracellular KLK5 activity in HaCaT cells and diminished secretion of IL-8 under inflammatory conditions triggered by TLR-2 ligands. This study points to the great potential of these GNP as a new intracellular delivery strategy for both small drugs and antibodies in the treatment of skin diseases such as Rosacea.

Minocycline is a commonly prescribed tetracycline antibiotic used for the treatment of a number of dermatological conditions including acne and rosacea. Long-term adverse effects of minocycline include cutaneous hyperpigmentation. Various treatment options have been suggested for the treatment of minocycline pigmentation. We report a case of a patient on long-term low-dose minocycline for the treatment of rosacea with type III minocycline hyperpigmentation. A comparison was made between Q-Switch Nd:YAG and picosecond laser over a nine 9-period with treatments spaced 1 month apart, with a clearance in the patient pigmentation after four treatments with picosecond laser.
