Association between rosacea and helicobacter pylori infection: A meta-analysis

BACKGROUND AND OBJECTIVES

The potential association between rosacea and a heightened prevalence of Helicobacter pylori (HP) infection has been previously suggested. However, existing studies offer inconsistent results. This systematic review and meta-analysis aimed to elucidate the relationship between rosacea and HP infection.

METHODS

We conducted comprehensive searches of PubMed, Embase, and Web of Science databases to identify relevant observational studies for our investigation. We utilized the random-effects model to aggregate the data to address the potential influence of heterogeneity among the studies on the outcome.

RESULTS

Our analysis incorporated twenty-five datasets from 23 case-control and cross-sectional studies, encompassing 51,054 rosacea patients and 4,709,074 controls without skin disease. The pooled results revealed a significantly higher prevalence of HP infection in individuals with rosacea compared to controls (odds ratio [OR]: 1.51, 95% confidence interval [CI]: 1.17-1.95, p<0.001; I2 = 79%). Subgroup analysis indicated an increased prevalence of HP infection in rosacea studies that utilized one (OR: 1.72, 95% CI: 1.11-2.66, p = 0.02; I2 = 76%) or more tests for HP infection (OR: 2.26, 95% CI: 1.29-3.98, p = 0.005; I2 = 56%). However, this association was not observed in population-based studies that determined HP infection based on prescription records for HP eradication drugs (OR: 0.90, 95% CI: 0.76-1.07, p = 0.024; I2 = 54%).

CONCLUSION

Rosacea may be significantly associated with a higher prevalence of HP infection. High-quality prospective studies with delicately controlled confounding factors are needed to determine if HP infection is a risk factor for rosacea.

Psychiatric comorbidities associated with rosacea: a propensity score-matched case-control study in the All of Us database

Using the ethnically diverse All of Us dataset, this study investigated the association between rosacea and various psychiatric disorders. The analysis identified a significant prevalence of major psychiatric conditions, most notably phobic disorder, OCD, dysthymia and generalized anxiety disorder in participants with rosacea. This association highlights the importance of addressing the psychological wellbeing of people with rosacea and calls for further research into the underlying pathophysiological connections.

Clinical characteristics of the well-defined upper eyelid vascular network pattern in patients with rosacea

BACKGROUND

Rosacea is a chronic inflammatory skin disease. The diagnosis is based on the symptoms and physical signs, which still lacks objective laboratory tests or imaging tests.

OBJECTIVES

To propose and evaluate the upper eyelid network pattern in rosacea.

METHODS

Participants included patients diagnosed with rosacea, other facial erythematous skin diseases, and normal controls, all of whom underwent full-face imaging utilizing the VISIA® system software. According to these images, researchers evaluated the condition of the upper eyelid vascular network, developed the grading scale and then compared the difference of distribution in the three groups.

RESULTS

The occurrence rate of upper eyelid vascular network in rosacea was significantly higher than that in other facial erythematous skin diseases (84.3 vs. 32.0%, P < 0.001) and normal controls (84.3 vs. 28.0%, P < 0.001). The upper eyelid vascular network pattern was proposed (none [no clearly reticular vessels], mild [10-50% area of reticular vessels], moderate-to-severe [>50% area of reticular vessels]). Moderate-to-severe grade was defined as well-defined upper eyelid vascular network pattern, which was specific to patients with rosacea (rosacea vs. other facial erythematous skin diseases, adjusted odds ratio [aOR] = 5.814, 95% confidence interval [CI]: 3.899-8.670) (rosacea vs. heathy controls, aOR = 12.628, 95% CI: 8.334-19.112). The severity of the well-defined pattern had no significant association with age, duration, and phenotypes of rosacea (P > 0.05).

CONCLUSION

The well-defined upper eyelid vascular network pattern specifically appeared in patients with rosacea, which could be a possible clue to the diagnosis of rosacea.

Associations of serum gamma-linolenic acid levels with erythema severity and anxiety/depression status in patients with rosacea

BACKGROUND

The development of rosacea is suggested to be closely associated with lipid metabolism, inflammation, and anxiety/depression. Gamma linolenic acid (GLA) is a key factor participating in lipid metabolism, which is also confirmed to regulate the inflammatory response. However, the associations of serum GLA levels with rosacea severity and psychological status still remain unclear.

OBJECTIVE AND LIMITATIONS OF THE STUDY

The present study aimed to investigate the associations of gamma linolenic acid (GLA), a key factor participating in lipid metabolism and the inflammatory response, with rosacea severity and psychological status. The present study still had some limitations. First, this study is a cross-sectional study and does not provide longitudinal evidence about the relationship between GLA and rosacea; Second, the cohort in this study is also relatively small, and a larger cohort is needed in further investigation to reveal the potential role of lipid metabolism in the pathogenesis of rosacea.

METHODS

A total of 62 rosacea patients were consecutively recruited. Patient's Self-Assessment (PSA) scale and Clinician Erythema Assessment (CEA) as well as 7-item Generalized Anxiety Disorder (GAD-7) and 9-item Patient Health Questionnaire (PHQ-9) were conducted to evaluate the degree of erythema severity and anxiety/depression, respectively. Serum GLA levels were determined by gas chromatography mass.

RESULTS

Lower levels of serum GLA in rosacea patients were observed (p<0.001), and subgroup analysis revealed that patients with higher-level GLA had lower scores of PSA, CEA, GAD-7 and PHQ-9. Moreover, Spearman correlation analysis uncovered that serum GLA levels were negatively associated with PSA, CEA, GAD-7 as well and PHQ-9 scores, respectively. Linear regression model found that serum GLA levels at baseline were a predictive factor for prognosis of clinical outcomes after 1-month conventional treatment.

CONCLUSION

The present study indicates that lower levels of serum GLA in rosacea patients are negatively associated with the degree of erythema and anxiety/depression status.

Topical ivermectin 1.0% cream in the treatment of ocular demodicosis

PURPOSE

Ocular demodicosis can cause debilitating ocular surface disease. As ivermectin is effective at reducing Demodex proliferation in rosacea, this study investigated the efficacy of topical ivermectin 1.0% cream in treating ocular demodicosis.

METHODS

This retrospective single-centre clinical practice chart analysis involved the off-label treatment of patients who had ocular demodicosis with topical ivermectin 1.0 % cream (Soolantra, Galderma Ltd, UK) applied nightly to the lid margins of both eyes for 3 months. Ocular surface health was assessed at baseline when the treatment was prescribed and followed up at 3 and 12 months after baseline. Slit lamp biomicroscopy was used to take digital images of the upper eyelid lashes. Manual image analysis with ImageJ was conducted by a masked assessor to quantify signs of ocular demodicosis including the number of lashes with collarettes, with visible Demodex tails and with follicle pouting.

RESULTS

Data from a total of 75 patients with ocular demodicosis were analysed for this study (mean age 66.6 ± 13.9 years, 44 female). The numbers of lashes with collarettes (Median [Interquartile range]: 8 [4-13] at baseline to 0 [0-2] at the final visit, p < 0.001) and lashes with follicle pouting (3 [1-5] at baseline to 0 [0-1.8] at the final visit, p < 0.001) decreased with treatment. Any sign of lashes with visible tails was eliminated by the final visit (p < 0.007). Fluorescein staining severity score also improved, particularly from baseline (1 [0-2]) to the second visit (0 [0-1], p < 0.001).

CONCLUSIONS

The findings of this study show evidence for the efficacy of a 3-month course of topical ivermectin 1.0% cream in treating ocular demodicosis as indicated by reduction in collarettes, follicle pouting and visible Demodex tails. More research is warranted to improve the diagnosis, management and monitoring of this condition which is often overlooked or misdiagnosed.

Treating rosacea with botulism toxin: Protocol for a systematic review and meta-analysis

BACKGROUND

Rosacea is a chronic inflammatory disease usually associated with persistent erythema and periodic flushing. This disease is difficult to treat, and the outcomes are often unsatisfactory and prone to recurrence. In recent years, botulinum toxin has been used as a new treatment for rosacea; however, its efficacy and safety remain under discussion. Although a systematic review of the effectiveness and safety of botulinum toxin has been previously conducted by other researchers, our systematic review and meta-analysis evaluate the efficacy of botulinum toxin from a more comprehensive and detailed perspective to provide evidence for clinicians.

METHODS

Any study using botulinum toxin for the treatment of rosacea was considered for the analysis.

RESULTS

A total of 22 studies were included, 9 of which were randomized controlled trials involving 720 subjects. After treatment, all studies showed varying degrees of improvement in patient signs and symptoms along with reduced Clinician's Erythema Assessment (CEA) scores. The improvement was maintained for several months, and the adverse effects were mild and self-limiting.

CONCLUSION

Botulinum toxin may be an effective treatment for patients with rosacea; however, further clinical evidence is needed to confirm its long-term efficacy and side effects. The study was preregistered with Prospero (CRD42022358911).

Increased risk of sleep disturbances in patients with rosacea: A nationwide population-based cohort study

Rosacea is a chronic inflammatory skin disorder linked to various mental disorders, but little is known about the impact of rosacea on sleep disorders. The aim of this study is to confirm the association of rosacea with sleep disorders using a large administrative data set. This nationwide population-based retrospective cohort study enrolled 1129 individuals with rosacea and 11 017 age- and sex-matched controls without rosacea from the Korean National Health Insurance System database from 2002 to 2015. The prevalence of sleep disorder (7.8%) was significantly higher in patients with rosacea than in controls (5.81%; p < 0.001). Rosacea was associated with an increased risk of sleep disorder (adjusted odds ratio [aOR], 1.287 [95% confidence interval (CI), 1.022-1.623]). Among a variety of sleep disorders, patients with rosacea were likely to have an increased risk of insomnia (aOR, 1.318 [95% CI, 1.002-1.743]). In subgroup analysis, female patients with rosacea (aOR, 1.297 [95% CI, 1.010-1.722]) and those with rosacea and dyslipidemia (aOR, 1.417 [95% CI, 1.062-1.891]) were at a higher risk of having a sleep disorder. Rosacea is associated with an increased risk of having sleep disorders. The management of modifiable risk factors is important for managing sleep disorders in patients with rosacea.

Association of Rosacea with Depressive and Anxiety Symptoms: A General Population Study

BACKGROUND

The association between rosacea and psychiatric comorbidity has been reported previously. However, there is a lack of general population studies about this subject area.

OBJECTIVES

The aim of this study was to the association between rosacea with depressive and anxiety symptoms at the population level.

METHODS

A clinical whole-body examination was performed by dermatologists for 1,932 subjects belonging to the Northern Finland Birth Cohort 1966 Study during the 46-year follow-up survey. The presence of depressive and anxiety symptoms was gathered by using validated Hopkins Symptom Checklist-25 (HSCL-25) included in the self-administered questionnaires. Binary logistic regression analysis was used to identify associations between rosacea and psychological symptoms.

RESULTS

Rosacea was found in dermatological evaluation in 15.1% of the study subjects (n = 292). In logistic regression analyses, after adjusting for confounding factors, those with rosacea had 1.6-fold (OR 1.55, 95% CI: 1.02-2.32) risk for psychiatric symptoms according to HSCL-25 when compared with controls. In separate analyses of the HSCL-25 depression subscale, the risk was increased, especially for depressive symptoms (OR 1.56, 95% CI: 1.10-2.18).

CONCLUSIONS

Patients with rosacea seem to have increased risk for depressive and anxiety symptoms in general population. Physicians treating patients with rosacea should pay more attention to the psychosocial health of patients.

Wound excision and closure by secondary intention and growth factor application in the management of rosacea complicated by giant rhinophyma

BACKGROUND

Rosacea is a significant problem, affecting 5.5% of the world population. Currently used treatment techniques such as transfer flaps and implants are insufficient to meet the needs of many patients, which suggests that alternative approaches are needed.

CASE REPORT

This report describes a case of rosacea complicated by giant rhinophyma treated with excision and closure by secondary intention and growth factor application. The patient was admitted to the Department of Dermatology at The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China, in July 2021, and underwent excision of the external nasal redundancy under general anesthesia. The postoperative wound was left open. The patient's wounds healed completely 2 months after surgery, and there was no recurrence at 6-month follow-up. The wounds recovered well, with only slight scarring.

CONCLUSION

The positive outcomes for this patient suggest that wound excision and closure by secondary intention and growth factor application may be beneficial for patients with rosacea complicated by giant rhinophyma.

Evidence for the Clinical Association between Demodex and Rosacea: A Review

BACKGROUND

Rosacea is a chronic inflammatory dermatological condition in humans, and its pathogenesis remains unclear. However, the development of rosacea is suspected to be related to Demodex, a microscopic commensal organism that resides in or near hair follicles and sebaceous glands. Although Demodex is known to be a host-specific, obligate commensal organism, it is currently difficult to be cultured in vitro to parasitize and infect other animal hosts. Therefore, direct evidence for a pathogenic role of Demodex in rosacea is currently lacking.

SUMMARY

As circumstantial evidence, non-invasive skin-detecting techniques have shown abnormally elevated numbers of Demodex in rosacea patients. Increased cytokine levels such as IL-10, IL-8, and IL-12p70 have been observed in human sebocytes following the Demodex challenge, and acaricides have been found to be effective in rosacea therapy, all point to a close relationship between Demodex and rosacea. Based on these findings, we conducted a comprehensive literature review to summarize the current state of knowledge, research insights, and clinical treatment recommendations for Demodex-associated rosacea, with the ultimate goal of improving patient outcomes.

Evaluation of Ocular and Systemic Oxidative Stress Markers in Ocular Rosacea Patients

Purpose

To investigate oxidative stress markers in tears and serum of patients with ocular rosacea and to examine their association with both ocular surface parameters and cutaneous rosacea subtypes.

Methods

This prospective study includes rosacea patients with ocular involvement and healthy controls. We performed ophthalmological examination of all participants and collected tear breakup time (TBUT), Schirmer, Meibomian gland dysfunction (MGD) and Ocular Surface Disease Index (OSDI) scores. We quantified the total antioxidant status (TAS), total oxidant status (TOS), and arylesterase (ARE) levels from tear and serum samples, and calculated the oxidative stress index (OSI). We also classified patients into phymatous, erythematotelangiectatic, papulopustular subtypes.

Results

We included 90 ocular rosacea patients and 30 healthy controls. Oxidative stress (TOS, OSI) levels were significantly higher (P < 0.01) and antioxidant levels (TAS, ARE) were significantly lower (P < 0.01) in both tear and serum samples of ocular rosacea patients as compared to controls. We found a significant positive correlation between the tear and serum values regarding oxidative stress parameters (P < 0.05). Besides, OSI was negatively correlated with TBUT and positively correlated with MGD score (meiboscore) and OSDI (P < 0.05). The Schirmer score was not correlated with OSI. No difference was found between the cutaneous subtypes with respect to TAS, TOS, ARE, and OSI results.

Conclusions

In this study, we identified oxidative stress markers in the serum and tears of ocular rosacea patients and showed their correlation with clinical signs of MGD, suggesting that oxidative stress contributes to ocular rosacea pathogenesis and that oxidative stress could be an indicator of MGD severity.

Idiopathic facial aseptic granuloma in children: Management and long-term follow-up

AIMS

The primary objective was to study long-term outcomes in children with idiopathic facial aseptic granuloma (IFAG). The secondary objectives were to describe the clinical polymorphism of this entity, the different therapeutic options, and the occurrence of rosacea in this population.

METHODS

We selected patients with a clinical diagnosis of IFAG seen in two different hospitals in Normandy between March 2016 and February 2021, and we collected clinical and therapeutic data from computerized medical records. A remote consultation based on recent photographs was performed to collect new data, and the children's parents were asked to complete a questionnaire between February and August 2021.

RESULTS

Ten children were included in this study. Nine patients presented with a single red to purplish nodule. One patient presented multiple papulopustular plaques. IFAG healed spontaneously without major sequelae, and this outcome was not influenced by any treatments. During follow-up, two patients developed childhood rosacea.

CONCLUSION

Although some clinical heterogeneity exists, early diagnosis and follow-up of IFAG is necessary to avoid unnecessary topical or systemic antibiotic treatments that do not shorten the disease course. IFAG appears to be a possible mode of entry for infantile rosacea.

Preferred practice patterns and review on rosacea

Rosacea is a chronic, inflammatory facial dermatosis commonly found in fair skin tone population. Recent studies have shown the increasing prevalence in the dark skin tone population as well. Ocular involvement is very common and can occur without cutaneous features. Common ocular features are chronic blepharoconjunctivitis with eyelid margin inflammation and meibomian gland dysfunction. Corneal complications include corneal vascularization, ulceration, scarring, and rarely, perforation. Diagnosis is largely based on clinical signs, although it is often delayed in the absence of cutaneous changes, particularly in children. The management ranges from local therapy to systemic treatment, depending on the severity of the disease. There is a positive association between demodicosis and rosacea; however, causality is always argued. In this review, we describe the epidemiology, clinical features, and treatment of rosacea and ocular rosacea.

Diabetic Patients With Rosacea Increase the Risks of Diabetic Macular Edema, Dry Eye Disease, Glaucoma, and Cataract

PURPOSE

Inflammation plays a role in diabetic eye diseases, but the association between rosacea and eye diseases in patients with diabetes remains unknown.

DESIGN

This retrospective cohort study used claims data from the National Health Insurance Research Database in Taiwan to investigate the association between rosacea and eye diseases in patients with diabetes.

MATERIALS AND METHODS

Taiwanese patients diagnosed as having diabetes mellitus between January 1, 1997, and December 31, 2013, and using any hypoglycemic agents were included and divided into rosacea and nonrosacea groups. After applying 1:20 sex and age matching and exclusion criteria, 1:4 propensity score matching (PSM) was conducted to balance the covariate distribution between the groups. The risk of time-to-event outcome between rosacea and nonrosacea groups in the PSM cohort was compared using the Fine and Gray subdistribution hazard model.

RESULTS

A total of 4096 patients with rosacea and 16,384 patients without rosacea were included in the analysis. During a mean follow-up period of 5 years, diabetic patients with rosacea had significantly higher risks of diabetic macular edema [subdistribution hazard ratio (SHR): 1.31, 95% confidence interval (CI): 1.05-1.63], glaucoma with medical treatment (SHR: 1.11, 95% CI: 1.01-1.21), dry eye disease (SHR: 1.55, 95% CI: 1.38-1.75), and cataract surgery (SHR: 1.13, 95% CI: 1.02-1.25) compared with diabetic patients without rosacea. A cumulative incidence analysis performed up to 14 years after the index date revealed that the risks of developing ocular diseases consistently increased over time. No significant differences in diabetic retinopathy, age-related macular degeneration, retinal vascular occlusion, ischemic optic neuropathy, optic neuritis, uveitis, or retinal detachment were identified according to rosacea diagnosis. However, we observed significant associations between rosacea and psoriasis, irritable bowel syndrome, anxiety, and major depressive disorder among patients with diabetes.

CONCLUSIONS

Rosacea is associated with diabetic macular edema, glaucoma, dry eye disease, and cataract development in diabetic patients, as well as increased risks of psoriasis, irritable bowel syndrome, anxiety, and depression in diabetic patients.

Clinical Evaluation of a Nature-Based Bakuchiol Anti-Aging Moisturizer for Sensitive Skin

BACKGROUND

Patients with sensitive skin find topical retinoid use for anti-aging purposes challenging due to irritation. Bakuchiol, a meroterpene from the Psoralea corylifolia seed, has retinol functionality through retinol-like regulation of gene expression.

OBJECTIVE

This research examined the tolerability, efficacy, and barrier effects of a nature-based bakuchiol-containing cleanser and moisturizer in subjects with sensitive skin.

METHODS

60 female subjects Fitzpatrick skin types I&ndash;V age 40&ndash;65 years with sensitive mild to moderate photodamaged skin were enrolled in this 4 week study. A sensitive skin panel was constructed: 1/3 eczema/atopic dermatitis, 1/3 rosacea, 1/3 cosmetic intolerance syndrome. Subjects used a nature-based cleanser and moisturizer twice daily and underwent transepidermal water loss (TEWL), corneometry, tolerability assessments, and efficacy assessments at baseline, 5&ndash;10 minutes post-application, and week 4.

RESULTS

The skin care products were well tolerated and efficacious (P&lt;0.001) in terms of investigator assessed improvement in visual smoothness, tactile smoothness, clarity, radiance, overall appearance, and global anti-aging. Cheek corneometry measurements demonstrated a statistically significant 16% increase in skin moisture content (P&lt;0.001).

CONCLUSION

A bakuchiol nature-based anti-aging moisturizer is well tolerated and effective in individuals with sensitive skin.J Drugs Dermatol. 2020;19(12): doi:10.36849/JDD.2020.5522.

Ocular Symptoms of Rosacea

The authors present case reports of two women, who were hospitalized in Department of Ophthalmology, University hospital Hradec Králové for ocular symptoms of rosacea. In the beginning there were relatively severe objective findings in the anterior segment of the eye in both cases - significant cornea graying with superficial and deep cornea vascularization in both eyes. On faces of both patients there were more or less typical sings of general illness. Especially in the first case there were severe papulopustules with crust all over the face. Subjectively Patients describe characteristic symptoms of dry eye. After dermatological consultation local and general anti-inflammatory treatment was set with consequent condition improving in both cases patients. In both cases we use two different general therapy formula according to literature (Azitromycin x Doxyhexal). In one case report, we found distinctive non-compliance during aftercare on our department with serious consequences. The purpose of our report is to point out ocular complications of rosacea and importance of oftalmologist´s and dermatologist´s cooperation during therapy of this illness with can lead to permanent damage of front segment of the eye and significant loss of visual acuity.

Optimizing Management of Otophyma: A Case Series Highlighting the Role of Surgical and Retinoid Therapy

Otophyma is a rare condition that can result in conductive hearing loss. Current otophyma literature does not examine validated treatment outcomes for patients. Utilizing a medical and surgical approach to maintain a patent canal can lead to significant objective improvements. The aim of this case series is to describe a combined successful approach in 3 cases from an academic, multidisciplinary center. The main outcomes analyzed were pre and post air-bone gap audiogram analysis and disimpaction frequency. The results showed that post-management, patient 1 had substantial improvement in hearing, recovering 49 dB in his right ear and 25 dB in his left ear, demonstrating near complete air-bone gap closure. Patient 2 showed a similar dermatologic and functional improvement, although objective audiometric assessment related to otophyma could not be performed due to coexisting chronic otitis media and cholesteatoma. Patient 3, in the 12 months prior to comanagement, had 8 bilateral disimpactions, and following comanagement had 2 disimpactions in 23 months. All 3 patients were pleased with the resultant functional and physical appearance following comanagement. By presenting this approach and objective measures of treatment, we hope to improve future clinical decision-making in a rare condition.

Association between Rosacea and Cardiovascular Diseases and Related Risk Factors: A Systematic Review and Meta-Analysis

BACKGROUND

Rosacea is a common inflammatory skin disorder. Several studies, but not all, have suggested a high prevalence of cardiovascular diseases (CVDs) in rosacea patients. This study is aimed at investigating the association between rosacea and CVDs and related risk factors.

METHODS

We performed a literature search through PubMed, Embase, and Web of Science databases, from their respective inception to December 21, 2019. Two reviewers independently screened the articles, extracted data, and performed analysis, following the PRISMA guidelines. Odds ratios (OR) or standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for outcomes. The included studies' quality was evaluated using the Newcastle Ottawa Scale (NOS).

RESULTS

The final meta-analysis included ten studies. The pooled analysis found no association between rosacea prevalence and the incidence of CVDs (OR 0.97; 95% CI 0.86-1.10). Rosacea was found to be significantly associated with several risk factors for CVDs (OR 1.17; 95% CI 1.05-1.31), including hypertension (OR 1.17; 95% CI 1.02-1.35), dyslipidemia (OR 1.34; 95% CI 1.00-1.79), and metabolic syndrome (OR 1.72; 95% CI 1.09-2.72). However, no association was found between rosacea and diabetes mellitus (OR 0.98; 95% CI 0.82-1.16). Among the biological parameters, a significant association was found between rosacea and total cholesterol (SMD = 0.40; 95% CI = -0.00, 0.81; p < 0.05), low-density lipoprotein cholesterol (SMD = 0.28; 95% CI = 0.01, 0.56; p < 0.05), and C-reactive protein (CRP) (SMD = 0.25; 95% CI = 0.10, 0.41; p < 0.05). We found no association between rosacea and high-density lipoprotein cholesterol (SMD = 0.00; 95% CI = -0.18, 0.18; p = 0.968) or triglycerides (SMD = 0.10; 95% CI = -0.04, 0.24; p = 0.171).

CONCLUSIONS

Although no significant association was found between rosacea and CVDs, rosacea was found to be associated with several of related risk factors. Patients with rosacea should pay more attention to identifiable CVD risk factors, especially those related to inflammatory and metabolic disorders.

Morbihan disease: a case report and differentiation from Melkersson-Rosenthal syndrome

We present a 32-year old woman with a 9-year history of upper facial swelling. A workup by the ophthalmology department led to the diagnosis of Melkersson-Rosenthal syndrome. Re-evaluation in our dermatology clinic confirmed a diagnosis of Morbihan disease. Herein, we review case reports and case series of upper facial swelling in the dermatologic and ophthalmologic literature. Although the two entities share histopathological changes, they tend to have different clinical presentations. Melkersson-Rosenthal syndrome appears to be more likely diagnosed in the ophthalmologic literature when the clinical presentation and histopathology may be more consistent with Morbihan disease. In a patient with upper facial swelling, an absence of orolabial swelling, and lack of facial neuropathy, we argue for a diagnosis of Morbihan disease over Melkersson-Rosenthal syndrome, especially if the patient has a history of rosacea.

Treating Inflammation in Rosacea: Current Options and Unmet Needs

Rosacea is a disease resulting from dysregulation of innate, adaptive, and neurovascular immune systems. Inflammatory pathways activated in rosacea can explain many of its signs and symptoms. Current treatments address some of these inflammatory processes, alleviating erythema and decreasing papules and pustules. However, for the majority of patients, complete clearance of these features is not currently achievable even with combination therapy. There is a need to address the spectrum of inflammatory processes involved in rosacea and for more efficacious agents with the goal of providing complete clearance for patients. J Drugs Dermatol. 2020;19(6): doi:10.36849/JDD.2020.5187.

Association of rosacea with inflammatory bowel disease: A MOOSE-compliant meta-analysis

Rosacea has been reported with several systemic comorbidities, but its relationship with inflammatory bowel disease (IBD) is unclear. Thus, our objective is to conduct a meta-analysis on the association of rosacea with IBD.We conduct a meta-analysis and searched MEDLINE, CENTRAL, and Embase databases for case-controlled and cohort studies that assessed the association of rosacea with IBD from inception to July 2nd, 2018. Two authors independently selected studies, extracted data, and assessed the risk of bias of included studies. Disagreement was resolved by discussion. We performed random-effects model meta-analysis to obtain the pooled risk estimates for Crohn disease (CD) and ulcerative colitis (UC) in patients with rosacea.We included three case-control and three cohort studies. The risk of bias of included studies was generally low. The meta-analysis on case-control studies showed marginally increased odds of CD (pooled odds ratio (OR) 1.30, 95% confidence interval (CI) 0.99-1.69) and a significantly increased odds of UC (pooled OR 1.64, 95% CI 1.43-1.89) in patients with rosacea. The meta-analysis on cohort studies demonstrated significant increased risk of CD (pooled hazard ratio (HR) 1.58, 95% CI 1.14-2.20) and UC (pooled HR 1.18, 95% CI 1.01-1.37) in patients with rosacea.The evidence indicates an association of rosacea with IBD. If patients with rosacea suffer from prolonged abdominal pain, diarrhea, and bloody stool, referral to gastroenterologists may be considered.

Acne and Rosacea: Special Considerations in the Treatment of Patients With Latin American Ancestry

Acne is a common disease among patients with Latin American ancestry. Its presentation is very similar to that in all skin types, but nodulocystic acne is more frequent in patients with oily and darker skin than in white Caucasians. Acne sequelae in patients with Latin American ancestry and with darker skin include postinflammatory hyperpigmentation (PIH) and atrophic and hypertrophic scars or keloids, with PIH being the most common complication affecting the quality of life of patients. Lately, more attention has been paid to rosacea in patients with darker skin. It has been seen that some of the patients, especially women, diagnosed with adult acne and who did not respond to treatment, were actually patients with rosacea. It is important to recognize the clinical characteristics of this disease in patients with darker skin in whom erythema and telangiectasia are difficult to observe. Here, we present the most relevant clinical characteristics of both diseases, as well as their treatment in patients with darker skin with Latin American ancestry. J Drugs Dermatol. 2019;18(3 Suppl):s124-126.

[THE RATIONALE FOR THE POSSIBLE ROLE OF DEMODEX FOLLICULORUM IN THE PATHOGENESIS OF ROSACEA]

The purpose of the study was to study the frequency of detection and population density of the mite in rosacea patients depending on the clinical form, the location of the morphological elements on the face and some parameters of the functional state of the skin. We observed 55 patients (38 women and 17 men) aged from 30 to 65 years old with disease duration from 6 months to 10 years. According to clinical forms, 35 had PPR and 20 - ETR (erythematous - telangiectatic rosacea). By location of the rash elements, the following types are distinguished: central, medial, asymmetric, lateral, and total. The mite was identified by a microscopic method. The functions of the skin barrier of the face skin: moisture, oiliness, dryness were determined using a bio-impedance analyzer (BIA). As shown by the results of the study of the above parameters in the observed patients, a high density of the mite population (> 5 per cm2) was noted in cases of total, medial and central type of their location. This indicator was in direct correlation with parameters such as skin fat content and moisture. 75% of patients in this group were diagnosed with PPR. In the group of patients with medium and low population density of mites (<5 per cm2), the lateral, asymmetric and central type of their location were dominated in 65% ​​of patients with ETNR. This group of patients showed low levels of skin fat and moisture, relatively high rates of dryness. Thus, the population density of the mites is dependent on the intensity of the anatomical location of the sebaceous glands of the face skin. An analysis of the results obtained in the study of the role of mite in the pathogenesis of rosacea led us to the conclusion: in rosacea patients, a correlation was found between the increase in the population density of mites, the type of element arrangement and the severity of dermatosis, which proves the role of the mite as one of the most frequent but not obligatory pathogenetic factors in the development of this dermatosis, especially its papulopustular form.

Epidemiology of benign essential blepharospasm: A nationwide population-based retrospective study in Taiwan

IMPORTANCE

This study provides a nationwide, population-based data on the incidence of benign essential blepharospasm in Asian adults.

BACKGROUND

To describe the incidence, patient demographics, and risk factors associated with benign essential blepharospasm.

DESIGN

Population-based retrospective study.

PARTICIPANTS AND SAMPLES

A total of 1325 patients with benign essential blepharospasm were identified.

METHODS

Patients with diagnosis of blepharopsasm between January 2000 and December 2013 were sampled using the Longitudinal Health Insurance Database 2000. Secondary blepharospasm that may be related to neurological, trauma, and ocular surface disease were excluded.

MAIN OUTCOME MEASURED

Multivariate conditional logistic regression was used to estimate the odds ratios for potential risk factors of benign essential blepharospasm.

RESULTS

The mean annual incidence was 0.10‰ (0.07‰ for males, and 0.12‰ for females). The peak incidence was in the 50 to 59-year-old age group (0.19‰). People living in urban regions have more risk of developing blepharospasm comparing to people living in less urban regions (p <0.01). White-collar workers also have higher chance of having blepharospasm (p<0.001). Significant difference between control group and case group in hyperlipidemia (p <0.001), sleep disorders (p <0.001), mental disorders (depression, anxiety, obsessive compulsive disorder) (p <0.001), dry eye-related diseases (dry eye, Sjögren's syndrome) (p <0.001), Parkinson's disease (p <0.004), and rosacea (p <0.021) were also identified.

CONCLUSIONS AND RELEVANCE

Higher level of urbanization, white-collar work, sleep disorders, mental health diseases, dry eye-related diseases, Parkinsonism, and rosacea are possible risk factors for benign essential blepharospasm.

Topical Oxymetazoline Cream 1.0% for Persistent Facial Erythema Associated With Rosacea: Pooled Analysis of the Two Phase 3, 29-Day, Randomized, Controlled REVEAL Trials

Background: Rosacea is a chronic dermatologic condition with limited treatment options. Methods: Data were pooled from two identically designed phase 3 trials. Patients with moderate to severe persistent erythema of rosacea were randomized to receive oxymetazoline cream 1.0% or vehicle once daily for 29 days and were followed for 28 days posttreatment. The primary efficacy outcome was the proportion of patients with ≥2-grade improvement from baseline on both Clinician Erythema Assessment (CEA) and Subject Self-Assessment (SSA) at 3, 6, 9, and 12 hours postdose, day 29. Results: The pooled population included 885 patients (78.8% female); 85.8% and 91.2% had moderate erythema based on CEA and SSA, respectively. The primary outcome was achieved by significantly more patients in the oxymetazoline than vehicle group (P<0.001). Individual CEA and SSA scores and reduction in facial erythema (digital image analysis) favored oxymetazoline over vehicle (P<0.001). The incidence of treatment-emergent adverse events was low (oxymetazoline, 16.4%; vehicle, 11.8%). No clinically relevant erythema worsening (based on CEA and SSA) was observed during the 28-day posttreatment follow-up period (oxymetazoline, 1.7%; vehicle, 0.6%). Conclusion: Oxymetazoline effectively reduced moderate to severe persistent facial erythema of rosacea and was well tolerated. J Drugs Dermatol. 2018;17(11):1201-1208.

Flushing Disorders Associated with Gastrointestinal Symptoms: Part 2, Systemic Miscellaneous Conditions

Flushing disorders with involvement of the gastrointestinal tract represent a heterogeneous group of conditions. In part 1 of this review series, neuroendocrine tumors (NET), mast cell activation disorders (MCAD), and hyperbasophilia were discussed. In this section we discuss the remaining flushing disorders which primarily or secondarily involve the gastrointestinal tract. This includes dumping syndrome, mesenteric traction syndrome, rosacea, hyperthyroidism and thyroid storm, anaphylaxis, panic disorders, paroxysmal extreme pain disorder, and food, alcohol and medications. With the exception of paroxysmal pain disorders, panic disorders and some medications, these disorders presents with dry flushing. A detailed and comprehensive family, social, medical and surgical history, as well as recognizing the presence of other systemic symptoms are important in distinguishing the different disease that cause flushing with gastrointestinal symptoms.

A report and follow up of a patient with disseminated superficial actinic porokeratosis (DSAP) undergoing novel systemic treatment with palifermin (a keratinocyte growth factor) during chemotherapy

Disseminated superficial actinic porokeratosis (DSAP) is an inherited dermatosis triggered by chronic ultraviolet light exposure. Cosmetic improvement has been noted with topical therapies or laser treatment. Lesions of DSAP are precancerous, having been reported to develop into squamous cell carcinomas (SCCs) or basal cell carcinomas (BCCs) occasionally. We describe a patient with longstanding DSAP who developed a primary CNS lymphoma. Palifermin (a keratinocyte growth factor analogue) was used as an adjuvant for his chemotherapy to minimize mucositis. Our patient noted marked clinical improvement of his DSAP following his chemotherapy for lymphoma. Follow-up has shown a sustained improvement of his DSAP with no development of any SCCs. Palifermin may be safe for use in individuals at high risk of developing SCCs and further research into keratinocyte growth factors and risk of development of SCC is warranted. Systemic chemotherapy appears to improve DSAP lesions.

Pivotal Trial of the Efficacy and Safety of Oxymetazoline Cream 1.0% for the Treatment of Persistent Facial Erythema Associated With Rosacea: Findings from the First REVEAL Trial

An unmet need exists for a safe, tolerable, effective treatment for moderate to severe persistent facial erythema in patients with rosacea. This pivotal phase 3, multicenter, double-blind study evaluated the efficacy and safety of topical oxymetazoline in patients with facial erythema associated with moderate to severe rosacea. Patients were randomly assigned to treatment with oxymetazoline hydrochloride cream 1.0% or vehicle applied once daily for 29 days, and were followed for 28 days posttreatment. The primary efficacy outcome was having at least a 2-grade decrease from baseline on both the Clinician Erythema Assessment (CEA) and the Subject Self-Assessment for rosacea facial redness (SSA) scales (composite success) at 3, 6, 9, and 12 hours postdose on day 29. Safety assessments included treatment-emergent adverse events (TEAEs) and posttreatment worsening of erythema (composite CEA/SSA increase of 1-grade severity from baseline; rebound effect). A total of 440 patients (mean age, 49.5 years; 78.9% females) were randomized (oxymetazoline, n=222; vehicle, n=218); most had moderate erythema. On day 29, significantly greater proportions of oxymetazoline recipients achieved the primary efficacy outcome at each time point (P less than 0.02) and overall (P less than 0.001) compared with vehicle recipients. The incidence of discontinuation due to TEAEs was low in both groups (oxymetazoline group, 1.8%; vehicle group, 0.5%). The most common TEAEs reported during the entire study period were application-site dermatitis, application-site erythema, and headache in the oxymetazoline group (1.4% each), and headache (0.9%) in the vehicle group. Following cessation of treatment, low proportions of patients experienced rebound effect (oxymetazoline group, 2.2%; vehicle group, 1.1%). Oxymetazoline applied to the face once daily for 29 days was effective, safe, and well tolerated in patients with moderate to severe persistent facial erythema of rosacea. <p><em>J Drugs Dermatol. 2018;17(1):97-105.</em></p>.

Evaluating and Optimizing the Diagnosis of Erythematotelangiectatic Rosacea

Erythematotelangiectatic rosacea is the most prevalent rosacea subtype. Multiple dermatologic conditions may mimic erythematotelangiectatic rosacea. The authors review a comprehensive approach to evaluating subjects with a suspected diagnosis of erythematotelangiectatic rosacea and discuss findings that may warrant further investigation. Differential diagnoses can be narrowed based on the presence of characteristics such as transient erythema, nontransient erythema, and telangiectasias. A thorough history and physical examination are critical in ruling out conditions such as dermatomyositis, lupus erythematosus, atopic dermatitis, and seborrheic dermatitis.

Increased risk of chronic kidney disease in patients with rosacea: A nationwide population-based matched cohort study

Background

Rosacea is a chronic inflammatory skin disorder. Inflammation and oxidative stress are involved in the etiopathogenesis of rosacea and chronic kidney disease (CKD). This study aimed to investigate the association between rosacea and CKD.

Methods

This population-based cohort study identified 277 patients with rosacea in the Taiwan National Health Insurance Research Database during 2001–2005. These patients were matched for age, sex, and comorbidities with 2216 patients without rosacea. All subjects were individually followed-up for 8–12 years to identify those who subsequently developed CKD

Results

The incidence rates of CKD per 1000 person-years were 16.02 in patients with rosacea and 10.63 in the non-rosacea reference population. After adjusting for other covariates and considering the competing risk of mortality, patients with rosacea remained at increased risk of CKD (adjusted sub-distribution hazard ratio (aSD-HR) 2.00; 95% confidence interval (CI) 1.05–3.82). The aSD-HRs (95% CI) for CKD were 1.82 (0.83–4.00) and 2.53 (1.11–5.75) for patients with mild and moderate-to-severe rosacea, respectively.

Conclusions

Rosacea is an independent risk factor for CKD. High rosacea severity and old age further increased CKD risk in patients with rosacea. Careful monitoring for CKD development should be included as part of integrated care for patients with rosacea.

Treatment of erythemato-telangiectatic rosacea with brimonidine alone or combined with vascular laser based on preliminary instrumental evaluation of the vascular component

The purpose of this study is to evaluate the outcome of a series of patients with erythematotelangiectatic rosacea (ETR) affected by persistent erythema and varying degree of telangiectasias being treated with brimonidine alone or combined with a vascular laser based on the type of vascular components preliminarily evaluated by clinical and instrumental observation. Ten patients affected by ETR were enrolled in a pilot, open study. Instrumental evaluation included erythema-directed digital photography by VISIA-CR™ system and X10 dermoscopy. Those patients showing marked background erythema and minimal telangiectasias (group A) were treated with a single application of brimonidine 0.33% gel, while patients showing both marked background erythema and marked telangiectasias (group B) were treated with a session of Nd:YAG laser and reevaluated 1 month later after a single application of brimonidine. An Investigator Global Assessment (IGA) of treatment outcome was performed at the end of treatment in both groups. In group A, 6 h after brimonidine application, a marked reduction of the background erythema was observed in all patients, and IGA was rated as excellent. In group B, 6 h following the application of brimonidine, a marked reduction of the background erythema was observed in all cases, while telangiectasias remained unchanged. A further treatment with brimonidine 1 month after the Nd:YAG laser session determined complete clearing of facial erythema, and IGA was rated as excellent. In conclusion, a preliminary evaluation of the vascular component by erythema-directed digital photography and dermoscopy in ETR may be helpful to select the most appropriate therapeutic strategy.

Can Hematologic Parameters be an Indicator of Metabolic Disorders Accompanying Rosacea?

Recently, diverse hematologic parameters have been used as an indicator of the presence or severity of inflammatory and cardiovascular diseases. Our aim was to investigate the ratios of neutrophils to lymphocytes (NL), monocytes to high-density lipoprotein (HDL) cholesterol (MHC), and platelets to lymphocytes (PL) in patients with rosacea in comparison with the control group and determine whether there was a correlation between these ratios and metabolic disorders in patients with rosacea. We conducted a case-control study on 61 patients with rosacea and 60 healthy controls between January 2015 and January 2016 at the Dermatology Outpatient Clinic, Mugla, Turkey. Demographic data, biochemical parameters, hematologic parameters and ratios, the presence of metabolic syndrome (MS), and the presence of insulin resistance (IR) in the participants were recorded. Sixty one patients with rosacea (16 men, 45 women) and 60 controls (13 men, 47 women) were included in the study. The NL ratio, mean levels of low-density lipoprotein (LDL) and total cholesterol, triglyceride, C-reactive protein (CRP), systolic and diastolic blood pressures, and the presence of IR were significantly higher in patients with rosacea than in controls. In the rosacea group, the MHC ratio was significantly higher in patients with rosacea with IR and MS. Moreover, only the MHC ratio was an independent predictor of MS according to univariate logistic regression analysis. The cutoff value of MHC on admission for predicting MS in patients with rosacea was 0.013.The higher levels of NL ratio and IR in the rosacea group corroborate the previous studies demonstrating a high level of cardiovascular risk factors in patients with rosacea. The MHC ratio may be used as a simple and inexpensive method to predict metabolic disorders in patients with rosacea.

[RISK-FSCTORS OF CARDIOVASCULAR DISEASE IN PATIENTS WITH ROSACEA]

The purpose of the research was to study the lipid profile, some indices of hemostasis and cytokine status of rosacea patients with severe climacteric syndrome. Serum lipid profile was studied by means of the following parameters: total cholesterol, high density lipoproteins (HDL), low density lipoproteins (LDL), triglycerides (the study of lipid profile was performed by the device "INTEGRAM +400" (Company "ROSH»). Haemostatic system was evaluated in terms of prothrombin, thrombin time. Content of fibrinogen, fibrinolytic activity, and prothrombin index were determined. The concentration of free VEGF (vascular endothelial growth factor) and IL-8 were measured by ELISA. The results of these studies suggest that the phenomenon of hyper coagulation and disorders in lipid profile of blood serum in patients with rosacea with climacteric syndrome can be considered as risk factors of cardiovascular disease. From the other side, as a powerful provocateur of increased permeability, atony and fragility of vessel walls, VEGF, IL-2, IL-8 may be directly related to the mechanism of the development of cardiovascular disease in rosacea patients.

Enlarged facial pores: an update on treatments

Enlarged facial pores remain a common dermatologic and cosmetic concern from acne and rosacea, among other conditions, that is difficult to treat due to the multifactorial nature of their pathogenesis and negative impact on patients' quality of life. Enlarged facial pores are primarily treated through addressing associative factors, such as increased sebum production and cutaneous aging. We review the current treatment modalities for enlarged or dense facial pores, including topical retinoids, chemical peels, oral antiandrogens, and lasers and devices, with a focus on newer therapies.

A systematic review and meta-analysis on Staphylococcus aureus carriage in psoriasis, acne and rosacea

Staphylococcus aureus might amplify symptoms in chronic inflammatory skin diseases. This study evaluates skin and mucosal colonization with S. aureus in patients with psoriasis, acne and rosacea. A systematic literature search was conducted. Both odds ratios (OR) for colonization in patients versus controls and the prevalence of colonization in patients are reported. Fifteen articles about psoriasis and 13 about acne (12 having a control group) were included. No study in rosacea met our inclusion criteria. For psoriasis, one study out of three controlled studies showed increased skin colonization (OR 18.86; 95 % confidence interval [CI] 2.20-161.99). Three out of the five studies that reported on nasal colonization showed significant ORs varying from 1.73 (95 % CI 1.16-2.58) to 14.64 (95 % CI 2.82-75.95). For acne one of the three studies that evaluated skin colonization reported a significant OR of 4.16 (95 % CI 1.74-9.94). A relation between nasal colonization and acne was not found. Limitations in study design and low sample sizes should be taken into consideration when interpreting the results. Colonisation with S. aureus seems to be increased in patients with psoriasis. This bacterial species, known for its potential to induce long-lasting inflammation, might be involved in psoriasis pathogenesis. Information on acne is limited. Prospective controlled studies should further investigate the role of S. aureus in chronic inflammatory skin diseases.

Four Diseases, Two Associations, One Patient: A Case of Frontal Fibrosing Alopecia, Lichen Planus Pigmentosus, Acne Rosacea, and Morbihan Disease

A 77-year-old woman born in the Dominican Republic presented with fullness of the glabella and medial eyebrows for 1 year followed by alopecia of the lateral eyebrows and frontal hairline. She stated that although she had a high hairline at baseline, it had receded in the past year. She had also noted central scalp hair thinning that started 6 years earlier. She denied all styling practices that used traction or chemical processes, although she admitted to hair dye and blow dryer use. She reported "acne" in the central face for decades and darkening of the skin on the lateral face for several years. Her medical history included hypertension, hyperlipidemia, hypothyroidism, benign paroxysmal positional vertigo, and treated breast ductal hyperplasia. Her medications were metoprolol, amlodipine, aspirin, levothyroxine, omeprazole, pravastatin, and meclizine; she denied starting any new medications within the past 2 years. Her family history was notable for androgenic pattern alopecia in a brother and a high hairline in her father. Review of systems was negative except for knee arthralgias and seasonal allergic rhinitis.

Brimonidine for erythema caused by rosacea

Brimonidine gel (Mirvaso-Galderma) became available in February of this year for the symptomatic treatment of facial erythema associated with rosacea in adults.1 Here, we review the evidence on brimonidine gel and consider its place in the management of erythema associated with rosacea.

Erythema of Rosacea: Validation of Patient's Self-Assessment Grading Scale

BACKGROUND

Facial erythema is a primary feature of rosacea. Currently, no validated scales exist that can accurately capture a patient's self-assessment of their own facial erythema. During phase 2 studies for brimonidine tartrate gel, a 5-point numeric rating scale was developed as a tool to allow subjects to provide an independent assessment of visible changes to the facial erythema associated with their rosacea.

OBJECTIVE

The objective of this study was to validate the revised patient's self-assessment (PSA) scale and evaluate it for statistical reliability and validity in quantification of facial erythema of rosacea.

METHODS

The validity of the PSA scale was evaluated by assessing the test-retest reliability, construct validity, and known-groups validity based on the data collected during a Phase 2b study on brimonidine gel for the treatment of persistent facial erythema of rosacea.

RESULTS

Based on the results of this evaluation, this PSA scale demonstrated test-retest reliability, construct validity, and known-groups validity.

LIMITATIONS

Study results are most generalizable to those with moderate to severe erythema.

CONCLUSION

The PSA is an appropriate scale to assess facial erythema associated with rosacea.

[IMPACT OF OPISTHORCHIS INVASION ON THE COURSE OF A SKIN PROCESS IN PATIENTS WITH ROSACEA]

The authors give the data-and results of their investigations of 47 patents with rosacea concurrent with chronic opisthorchiasis (Group 1) and 40 patients with rosacea without opisthorhiasis (Group 2): It is found that the severer clinical manifestations of rosacea are, the lower the quality of life is in patients. The patients with rosacea concurrent with chronic opisthorchiasis were found to have severe clinical forms. Rosacea diagnostic rating scores was 1.1-fold higher than in the patients without helminthiasis, suggesting a severer course. Quality-of-life dissatisfaction in patients with rosacea concurrent with chronic opisthorchiasis was significantly higher than in those with rosacea only.

The association of the sebum excretion rate with melasma, erythematotelangiectatic rosacea, and rhytides

BACKGROUND

Rosacea and melasma are two common skin conditions in dermatology. Both conditions have a predilection for the centrofacial region where the sebaceous gland density is the highest. However it is not known if sebaceous function has an association with these conditions.

AIMS AND OBJECTIVES

We aimed to assess the relationship between facial glabellar wrinkle severity and facial sebum excretion rate for individuals with rosacea, melasma, both conditions, and in those with rhytides. Secondly, the purpose of this study was to utilize high resolution 3D facial modeling and measurement technology to obtain information regarding glabellar rhytid count and severity.

MATERIALS AND METHODS

A total of 21 subjects participated in the study. Subjects were divided into four groups based on facial features: rosacea-only, melasma-only, rosacea and melasma, rhytides-only. A high resolution facial photograph was taken followed by measurement of facial sebum excretion rate (SER).

RESULTS

The SER was found to decline with age and with the presence of melasma. The SER negatively correlated with increasing Wrinkle Severity Rating Scale. Through the use of 3D facial modeling and skin analysis technology, we found a positive correlation between clinically based grading scores and computer generated glabellar rhytid count and severity.

CONCLUSION

Continuing research with facial modeling and measurement systems will allow for development of more objective facial assessments. Future studies need to assess the role of technology in stratifying the severity and subtypes of rosacea and melasma. Furthermore, the role of sebaceous regulation may have important implications in photoaging.

[Capillary fragility and some hemostatic parameters in patients with rosacea]

The aim of the study was to investigate the association between capillary fragility and some hemostatic parameters, lipid profile in patients with rosacea. 50 patients (30 women and 20 men) aged 35 to 65 years were under observation. Control group consisted of 50 healthy persons, adequate to comparison group by sex and age. To determine the resistance of the capillary, Rumpel-Leede cuff (tourniquet test) was used which consists in determining the formation of petechial hemorrhages on the skin in the area of ​​short-term increase in venous pressure. The hemostatic system was evaluated in terms of prothrombin and thrombin time. Content of fibrinogen and fibrinolytic activity of blood were determined also. The serum lipid profile was studied by means of the following parameters: total cholesterol, triglycerides, HDL (high density lipoprotein), LDL (low density lipoproteins). The survey revealed that in 25 patients the arm cuff test was positive, whereas in the control group, only 2 cases it was weakly positive. Manifestations of hypercoagulation were found in half of patients with a positive cuff test, almost in half of the patients an increased level of fibrinogen and the reduced fibrinolytic activity in blood serum has been revealed. Significant correlation with lipid metabolism have not been identified. Phenomenon of hypercoagulation in rosacea patients on the one hand suggests the existence of processes of microcoagulation, on the other hand the connection with the results of a cuff test can be used to predict the severity of the dermatosis and the possible risk for developing of cardiovascular disease.

Demodex Mite, Rosacea and Skin Melanoma; Coincidence or Association?

OBJECTIVE

To examine the possible associations between Demodex folliculorum and a number of skin diseases.

METHODS

Standardized skin surface biopsy samples were obtained from the cheeks of 144 patients with histopathologically proven basal cell carcinoma (BCC, n = 27), squamous cell carcinoma (SCC, n = 28), melanoma (n = 23), discoid lupus erythematosus (DLE, n = 32), and rosacea (n = 34). Thirty-four sex- and age-matched healthy volunteers served as controls. Mite density (per cm2) and infestation (density ≥ 5) were compared between the controls and patients.

RESULTS

Mite infestation rates (%) did not differ significantly between the controls (20.6) and patients with BCC (22.2, p = 0.88), SCC (17.9, p = 0.79), melanoma (4.3, p = 0.08), and DLE (21.9, p = 0.90). Compared with the controls, the mite infestation rate was significantly higher in patients with rosacea (47.1, p = 0.02, odds ratio: 3.43, 95% confidence interval: 1.18-9.99). The mean mite density did not differ significantly between the controls (4.11 ± 2.17) and patients with BCC (5.34 ± 2.35, p = 0.75), SCC (3.57 ± 2.01, p = 0.38), and DLE (3.56 ± 1.34, p = 0.83), whereas it was significantly higher in patients with rosacea (8.78 ± 3.58, p = 0.02) and lower in patients with melanoma (1.89 ± 0.69, p = 0.02).

CONCLUSIONS

D. folliculorum may be associated with rosacea and melanoma but not with BCC, SCC, or DLE.

Self regressing skin-colored papules with acneiform scarring over the face

Lupus miliaris disseminata faciei is a chronic inflammatory dermatosis of unknown etiology, which mostly involves the face in young adults. Earlier attempts had been made to relate it to tuberculosis, rosacea, and sarcoidosis without any strong evidence. For the past few years it has been considered as a distinct entity by various authors and was given a new nomenclature, "facial idiopathic granulomas with regressive evolution" (FIGURE). We also support this new nomenclature and present a young man with facial idiopathic granulomas and scarring consistent with this diagnosis.
