RESUMO

BACKGROUND/OBJECTIVE: Skin diseases, especially those with visible manifestation, are considered to cause a major influence on global mental health. Therefore, we determined the prevalence and severity of anxiety, depression, and suicidal ideation in a large sample of patients with facial dermatoses, namely acne, rosacea, folliculitis, and perioral dermatitis. METHODS: The mental health of patients with facial dermatoses and respective controls was assessed using the Hospital Anxiety and Depression Scale and questions concerning suicidal ideation. RESULTS: The study included 543 patients with facial dermatoses and 497 healthy individuals. Anxiety was present in 37.6% of the patients (14.9% of controls), depression in 21.7% (6.8%), and suicidal thoughts in 9.8% (3.2%) (p < 0.001). Acne patients demonstrated the highest anxiety and depression subscale scores (mean ± standard deviation: 7.1 ± 0.25, 95% confidence interval (CI): 6.58-7.56; controls: 5 ± 0.23, 95% CI: 4.57-5.49). In rosacea 30% of the patients had depression symptoms (adjusted odds ratio (OR): 7.216, 95% CI: 4.122-12.632, p < 0.001), while in folliculitis patients 15.4% (OR: 3.138, 95% CI: 1.241-7.936, p = 0.016) had suicidal thoughts. Patients with anxiety symptoms and suicidal thoughts were on average younger than those without (28.3 ± 0.76 vs. 31.2 ± 0.66 years, p = 0.001 and 25.3 ± 0.98 vs. 30.5 ± 0.55 years, p = 0.007, respectively). CONCLUSION: Acne and rosacea are associated with anxiety, depression, and suicidal ideation in Lithuanian patients. Younger patients are more prone to report such symptoms than older ones.

RESUMO

Skin aging is a complex biologic process influenced by a combination of intrinsic and extrinsic factors. Aging skin shows wrinkles, uneven tone, loss of elasticity, and thinning. Skin health is considered one of the principal factors representing overall well-being and the perception of health in humans; therefore, anti-aging strategies to combat aging signs and dysfunction have been developed over the last decades. Understanding the mechanism behind skin aging is required for elucidation of the mechanism of action and, hence, the potential benefits of the claimed anti-aging products. In this review, preventive measurements, cosmetologic strategies, and photoprotection (systemic antioxidants, ultraviolet and filters), as well as the mechanisms of action and the effectiveness of topical pharmaceutical agents, such as antioxidants (vitamins, polyphenols, and flavonoids) and cell regulators (retinols, peptides, hormones, and botanicals), are presented.

RESUMO

Acne vulgaris is potentially a severe skin disease associated with colonization of the pilo-sebaceous unit by the commensal bacterium Propionibacterium acnes and inflammation. P. acnes is considered to contribute to inflammation in acne, but the pathways involved are unclear. Here we reveal a mechanism that regulates inflammatory responses to P. acnes. We show that IL-1ß mRNA and the active processed form of IL-1ß are abundant in inflammatory acne lesions. Moreover, we identify P. acnes as a trigger of monocyte-macrophage NLRP3-inflammasome activation, IL-1ß processing and secretion that is dependent on phagocytosis, lysosomal destabilization, reactive oxygen species, and cellular K+ efflux. In mice, inflammation induced by P. acnes is critically dependent on IL-1ß and the NLRP3 inflammasome of myeloid cells. These findings show that the commensal P. acnes-by activating the inflammasome-can trigger an innate immune response in the skin, thus establishing the NLRP3-inflammasome and IL-1ß as possible therapeutic targets in acne.

RESUMO

The expression of enzymes involved in leukotriene and prostaglandin signalling pathways, of interleukins 6 and 8 and of peroxisome proliferator-activated receptors in sebaceous glands of acne-involved facial skin was compared with those of non-involved skin of acne patients and of healthy individuals. Moreover, 5-lipoxygenase and leukotriene A(4) hydrolase were expressed at mRNA and protein levels in vivo and in SZ95 sebocytes in vitro (leukotriene A(4) hydrolase > 5-lipoxygenase), while 15-lipoxygenase-1 was only detected in cultured sebocytes. Cyclooxygenase-1 and cyclooxygenase-2 were also present. Peroxisome proliferator-activated receptors were constitutively expressed. Enhanced 5-lipoxygenase, cyclooxygenase 2 and interleukin 6 expression was detected in acne-involved facial skin. Arachidonic acid stimulated leukotriene B(4) and interleukin 6 release as well as prostaglandin E(2) biosynthesis in SZ95 sebocytes, induced abundant increase in neutral lipids and down-regulated peroxisome proliferator-activated receptor-alpha, but not receptor-gamma1 mRNA levels, which were the predominant peroxisome proliferator-activated receptor isotypes in SZ95 sebocytes. In conclusion, human sebocytes possess the enzyme machinery for functional leukotriene and prostaglandin pathways. A comprehensive link between inflammation and sebaceous lipid synthesis is provided.
