Comparative Study
Nationwide Assessment of Cause-Specific Mortality in Patients with Rosacea: A Cohort Study in Denmark.
Emerging data suggest that rosacea is associated with several comorbidities; however, the causes of mortality in patients with rosacea have not yet been investigated. ⋯ We observed a significantly increased risk of death due to gastrointestinal diseases (primarily hepatic disease) in patients with rosacea; however, we found no increased risk of death due to other causes such as cardiovascular or neurological diseases. Although this does not necessarily imply a causal link, the findings underscore the association between rosacea and gastrointestinal disease, but also that rosacea may be associated with increased risk factors, including alcohol consumption.

Die Rosazea ist durch vielfältige vaskuläre Veränderungen gekennzeichnet. Neben Teleangiektasien und Erythemen treten häufig auch sogenannte "Flushings" auf. Haupteinsatzgebiete von Licht- und Lasersystemen sind diese vaskulären Veränderungen, wie Erytheme und Teleangiektasien. ⋯ Die klassische chirurgische Abtragung stellt eine Möglichkeit zur Behandlung dar, häufig kommt es hierbei jedoch intraoperativ zu stärkeren Blutungen. Alternativmethode ist die Elektrochirurgie und die Dermabrasion, wobei bei beiden Methoden Narbenbildungen auftreten können. Neuere Methoden wie die CO2 -Laserabtragung, eventuell in Kombination mit der Erbium:YAG-Abtragung, stellen sichere und komplikationsärmere Varianten dar.

Light-emitting diodes downregulate cathelicidin, kallikrein and toll-like receptor 2 expressions in keratinocytes and rosacea-like mouse skin.
Cathelicidin (LL-37), Toll-like receptor 2 (TLR-2) and kallikreins (KLKs) are key inflammatory mediators in rosacea. Laser or light-based devices have been successfully used for rosacea. We investigated the effects of light-emitting diodes (LEDs) on LL-37, KLKs, TLR-2 and protease activity in cultured normal human epidermal keratinocytes (NHEKs) and rosacea-like mouse skin (RLMS). ⋯ LED at 630 and 940 nm downregulated TLR-2, KLK5 and LL-37 expressions and protease activity in NHEK and RLMS. Thus, LEDs may be promising for rosacea treatment. However, clinical trials are required for further study.
