BACKGROUND: Facial erythema is a frequent and often distressing complaint of patients with rosacea. Treatment of facial erythema with botulinum toxin has previously been proposed and reported. However, the current literature has mixed results. OBJECTIVE: The primary objective of this study was to evaluate the safety and efficacy of intradermal abobotulinumtoxinA on facial erythema of rosacea. MATERIALS AND METHODS: Twenty-five subjects aged 35 to 70 years with Fitzpatrick skin Types I to IV and facial erythema of erythematotelangiectatic rosacea were enrolled in the trial...

BACKGROUND: Persistent erythema and severe rosacea flushing can cause significant physical discomfort and emotional stress to patients. Currently, no satisfactory treatments are available. METHODS: We report two cases of refractory flushing and erythema of rosacea that were successfully treated with intradermal botulinum toxin injections. RESULTS: Good cosmetic results were achieved for both patients. The side effects during and after treatment were mild pain and localized bruising; these symptoms resolved within several days without further treatment...

Refining diagnostic criteria has identified key characteristics differentiating rosacea, a chronic skin disorder, from other common cutaneous inflammatory conditions. The current classification system developed by the National Rosacea Society Expert Committee consists of erythematotelangiectatic, papulopustular, phymatous, and ocular subtypes. Each subtype stands as a unique entity among a spectrum, with characteristic symptoms and physical findings, along with an intricate pathophysiology. The main treatment modalities for rosacea include topical, systemic, laser, and light therapies...

Manal Abokwidir, Steven R Feldman
BACKGROUND: Rosacea is a chronic inflammatory skin condition associated with four distinct subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular. PURPOSE: To review the different kinds of management for all subtypes. METHODS: We divided rosacea management into three main categories: patient education, skin care, and pharmacological/procedural interventions. RESULTS: Flushing is better prevented rather than treated, by avoiding specific triggers, decreasing transepidermal water loss by moisturizers, and blocking ultraviolet light...

Rosacea fulminans or pyoderma faciale is a rare cutaneous disorder that usually affects women usually between the ages of 15-46. The disease is characterized by sudden onset of papules, pustules, cysts, and painful coalescing nodules with red-cyanotic centrofacial erythema. Although its etiology remains unknown, hormonal, immunological, and vascular factors have been reported. Early diagnosis and prompt treatment should minimize unsightly scars. We report a case of a 33-year-old female patient treated with traditional doses of doxycycline, with improvement of the lesions and regression of the condition in two months...

Host defense peptides/proteins (HDPs), also known as antimicrobial peptides/proteins (AMPs), are key molecules in the cutaneous innate immune system. AMPs/HDPs historically exhibit broad-spectrum killing activity against bacteria, enveloped viruses, fungi and several parasites. Recently, AMPs/HDPs were shown to have important biological functions, including inducing cell proliferation, migration and differentiation; regulating inflammatory responses; controlling the production of various cytokines/chemokines; promoting wound healing; and improving skin barrier function...

Demodicidosis is a common infestation and should be considered in the differential diagnosis of recurrent or recalcitrant perioral dermatitis or rosacea-like eruptions of the face. We report on a 34-year-old male, who presented with facial erythema and desquamation accompanied by a pruritic sensation. Dermoscopic examination revealed Demodex tails and Demodex follicular openings, both specific features of this entity. Microscopically, standardized skin surface biopsy test was pathogenic and the patient had positive response to anti-demodectic drugs...

INTRODUCTION: Numerous intrinsic and extrinsic factors have been associated with the pathophysiology of rosacea, including dysregulation of innate immunity. A high level of cathelicidin antimicrobial peptides (e.g., LL-37) has been shown in the facial skin of patients with rosacea. Excessive production of both LL-37 and KLK5, the serine protease responsible for its cleavage, has been suggested to play a role in the pathophysiology of rosacea. Ivermectin 10 mg/g cream, indicated for the treatment of inflammatory lesions of rosacea, is reported to have dual anti-parasitic and anti-inflammatory properties...

Rosacea is a chronic dermatological disorder with a variety of clinical manifestations localized largely to the central face. The unclear etiology of rosacea fosters therapeutic difficulty; however, subtle clinical improvement with pharmacologic treatments of various drug categories suggests a multifactorial etiology of the disease. Factors that may contribute to disease pathogenesis include immune abnormality, vascular abnormality, neurogenic dysregulation, presence of cutaneous microorganisms, UV damage, and skin barrier dysfunction...

Rosacea is a chronic relapsing inflammatory skin disease with high prevalence world-wide. Recent research suggests that dysregulation of innate and adaptive immune pathways as well as neuro-vascular changes are present, with different degrees of importance in the various subtypes. Neither the etiology, genetics, nor pathophysiological basis of the vascular, inflammatory or fibrotic changes are well understood. The clinical spectrum comprises a huge variability from erythema (vasodilation) to papules/pustules (inflammatory infiltrate) to phymata (fibrosis, glandular hyperplasia) making it a valuable human disease model to understand the interplay between the neurovascular and immune systems as well as the progression from chronic inflammation to fibrosis in skin...

BACKGROUND: Rosacea is a common inflammatory skin condition that shares genetic risk loci with autoimmune diseases such as type 1 diabetes mellitus (T1DM) and celiac disease. A recent genomewide association study identified 90 genetic regions associated with T1DM, celiac disease, multiple sclerosis, and/or rheumatoid arthritis, respectively. However, a possible association with rosacea was not investigated. OBJECTIVE: We evaluated the association between rosacea and T1DM, celiac disease, multiple sclerosis, and rheumatoid arthritis, respectively...

SM comprises a heterogeneous group of disorders, characterized by an abnormal accumulation of clonal MCs in 1 or more tissues, frequently involving the skin and BM. Despite the fact that most adult patients (>90%) carry the same genetic lesion (D816V KIT mutation), the disease presents with multiple variants with very distinct clinical and biologic features, a diverse prognosis, and different therapeutic requirements. Recent advances in the standardization of the study of BM MC by MFC allowed reproducible identification and characterization of normal/reactive MCs and their precursors, as well as the establishment of the normal MC maturational profiles...

Rosacea is a common chronic skin condition that displays a broad diversity of clinical manifestations. Although the pathophysiological mechanisms of the four subtypes are not completely elucidated, the key elements often present are augmented immune responses of the innate and adaptive immune system, and neurovascular dysregulation. The most common primary feature of all cutaneous subtypes of rosacea is transient or persistent facial erythema. Perilesional erythema of papules or pustules is based on the sustained vasodilation and plasma extravasation induced by the inflammatory infiltrates...

IMPORTANCE: To our knowledge, this is the first study on rosacea to formally define genetic and environmental contributions. OBJECTIVES: To study a cohort of identical and fraternal twins to determine whether genetic factors contribute to rosacea development and, if genetic factors are present, quantitatively estimate the genetic contribution, as well as to identify environmental factors that correlate with rosacea by controlling for genetic susceptibility. DESIGN, SETTING, AND PARTICIPANTS: Identical and fraternal twins were surveyed regarding risk factors implicated in rosacea...

Rosacea is a chronic inflammatory skin condition that affects approximately 16 million Americans. Four distinct subtypes of rosacea have been recognized, with transient and nontransient facial flushing, telangiectasia, and inflammatory papules and pustules being among the more commonly recognized features. Although the exact pathogenesis of rosacea is unknown, dysregulation of the innate immune system, overgrowth of commensal skin organisms, and aberrant neurovascular signaling may all have a role in promoting the clinical features of rosacea...
