    • Arch Dermatol Res. 2021 Sep 14. doi: 10.1007/s00403-021-02277-0. Online ahead of print. ABSTRACT Botulinum toxin A (BTX-A) injections have become the most popular noninvasive cosmetic procedures performed worldwide. With growing interest, investigators continue to uncover an expanding array of aesthetic indications for BTX-A. Botulinum toxin A has been used off-label in the management of masseter hypertrophy for facial slimming, platysmal bands, nasal 'bunny' lines, perioral rhytides, gummy smile and scars, to name a few. Interestingly, the injection of multiple microdroplets of dilute BTX-A into the dermis, sometimes referred to as 'microbotox', has been investigated as a tool for facial rejuvenation. A handful of prospective studies and case series have demonstrated the benefit of BTX-A in the treatment of facial erythema and improving skin texture. The aim of this review is to summarize and appraise currently available data on the role of BTX-A in treating facial erythema and skin quality, with a special focus on potential pathophysiologic mechanisms.

    • Dermatology. 2021 Sep 7:1-6. doi: 10.1159/000518220. Online ahead of print. ABSTRACT BACKGROUND: The prevalence and impact of pruritus, pain, and other sensory symptoms in skin diseases are poorly known. OBJECTIVE: To assess the frequency of these symptoms with dermatoses and their association with depression using data from the "Objectifs Peau" survey. METHODS: A representative sample of 20,012 French individuals was created using the usual quota method. RESULTS: When patients suffered from both pruritus and skin pain, they had a higher relative risk of psychological suffering (2.9) than those who suffered only from pruritus (1.4) or skin pain (1.2). Pruritus was reported in 48.55% of patients with acne, 43.24% with mycoses, 44.35% with warts, and 36.51% with rosacea. For skin pain, the results were 11.22%, 27.59%, and 16.13% for atopic dermatitis, acne, and warts, respectively. Other unpleasant sensations, such as tingling or burning, were also frequently reported. CONCLUSION: Pruritus, pain, or other sensory symptoms were found to be common not only in classic pruritic skin diseases but also in acne, rosacea, or warts. The association of pruritus and pain dramatically increased psychological suffering. These symptoms must be systematically searched for in patients, especially since new therapeutic possibilities are emerging for the symptomatic treatment of pruritus.

    • Arch Dermatol Res. 2021 Sep 12. doi: 10.1007/s00403-021-02279-y. Online ahead of print. ABSTRACT Rosacea is a chronic inflammatory skin condition that is associated with multiple systemic comorbidities, with the strongest evidence linking rosacea to hypertension, dyslipidemia, inflammatory bowel disease, and anxiety and depression. To assess dermatologists' awareness of and screening practices for rosacea comorbidities, we developed a survey that was distributed to attendings and residents across four academic dermatology departments in Massachusetts. A total of 73 dermatologists with varying experience participated in the study. Findings demonstrated significant knowledge and practice gaps among academic dermatologists in managing systemic comorbidities in rosacea. In addition, dermatologists' awareness of rosacea comorbidities was negatively correlated with number of years out of residency training, highlighting the need to address this knowledge gap through increased continuing medical education. Importantly, we observed a low screening frequency despite a high awareness of the association between rosacea and ocular comorbidities, suggesting that additional financial, institutional, or practice barriers likely contribute to the low screening rate.

    • Vestn Otorinolaringol. 2021;86(4):95-98. doi: 10.17116/otorino20218604195. ABSTRACT One of the frequent causes of a significant increase in the external nose, forming a persistent deformity of the face, as well as leading to a non-standard clinical picture is rhinophyma disease. The article considers some historical data, epidemiology, peculiarities of pathogenesis, as well as the basics of surgical treatment tactics along with possible preventive measures against rhinophyma. At present, the treatment of this pathology presents great difficulties. Despite the many surgical methods, rhinophyma is poorly treatable, often relapses and leaves no less noticeable disfigurement of the face in the postoperative period. In this regard, there is a constant search for new surgical methods, which has not only medical but also important social significance.

ABSTRACT INTRODUCTION: At present, some studies have reported that nasal rosacea may be an independent disease, but phenotypic characteristics and risk factors for nasal rosacea remain unknown. This study aimed to clarify the clinical features and explore the risk factors for nasal rosacea. METHODS: A hospital-based retrospective study was conducted, including 1615 rosacea patients and 1501 healthy individuals. The patients were divided into three groups based on the involved areas of the lesions (non-nasal, intermediate and nasal rosacea group). Their demographic data and clinical features were obtained from patients' medical records, and risk factors of nasal rosacea were analyzed. RESULTS: There were 927 (57.4%), 647 (40.1%) and 41 (2.5%) cases in the non-nasal, intermediate and nasal rosacea groups, respectively. Of 41 patients with nasal rosacea, all (100.0%) had fixed erythema and 17 cases (41.5%) had phymatous changes. Compared with control group, male gender (adjusted odds ratio [aOR] = 2.39, 95% confidence interval [CI] = 1.14, 4.99), obesity (aOR = 3.19, 95% CI 1.86, 11.79) and alcohol use (aOR = 1.58, 95% CI 1.22, 5.40) were risk factors for nasal rosacea, but these three factors were not risk factors for non-nasal rosacea and intermediate rosacea groups. Among patients with nasal lesions (compared with patients without nasal phymatous changes), family history of rosacea was a risk factor (aOR = 2.12, 95% CI 1.01, 4.46) for nasal phymatous changes and Fitzpatrick IV skin type was a protective factor (aOR = 0.49, 95% CI 0.28, 0.86). CONCLUSION: Nasal rosacea has relatively specific clinical features and independent risk factors, suggesting that it may be a special type of rosacea.

ABSTRACT Rosacea is a common chronic skin disease affecting mostly people aged 40 and above, with currently no cure. When it affects the eyelids and periocular skin, it leads to dry eye and potentially corneal damage. Research performed over the last decade shed light into the potential mechanisms leading to skin hypersensitivity and provided promising avenues for development of novel, rational therapeutics aimed at reducing the skin inflammatory state. In this review, we discuss the current knowledge on the mechanisms of rosacea in general and of periocular skin-affecting disease in particular, identify key questions that remain to be answered in future research, and offer a disease model that can explain the key characteristics of this disease, with particular emphasis on a potential positive feedback loop that could explain both the acute and chronic features of rosacea.
