Treatment of Common Dermatologic Conditions.

Dermatologic concerns are discussed in about a third of all primary care visits. This review discusses treatments for common dermatologic diagnoses addressed in primary care settings, with an emphasis on new and emerging treatments. Topical, oral, and injectable treatment of common forms of alopecia, facial rashes, atopic dermatitis, psoriasis, seborrheic dermatitis, and stasis dermatitis will be discussed to help increase comfort in prescribing and alert providers to common side effects or complications of more intensive treatments used by dermatologists.

A Retrospective Review of a Cohort of Patients with Periorificial Dermatitis Treated with Sarecycline.

Introduction: Periorificial dermatitis (POD) is a common, chronic, inflammatory facial skin rash that presents as tiny papules and papulopustules with underlying eczematous-like patches, typically confined to the perioral, perinasal, and periorbital areas. There is currently no Food and Drug Administration (FDA)-indicated treatment for POD; however, broad-spectrum antibiotics are efficacious as a treatment option. Broad-spectrum antibiotics negatively impact gut flora and lead to antibiotic resistance. Narrow-spectrum tetracyclines, such as sarecycline, have a low potential for promoting bacterial resistance and gastrointestinal issues. Objective: We conducted a retrospective chart review in order to evaluate the efficacy of sarecycline in a cohort of patients diagnosed with POD that were treated with sarecycline. Methods: A review of medical records was completed using an electronic medical record. Inclusion criteria included males and females aged 18 to 95 with a diagnosis of POD, treated with sarecycline with a documented follow-up. Results: Six patients met inclusion criteria, all of which had shown improvement with no reported side effects. Of the six patients, four were female and two were male and the patient ages ranged from 26 to 58 years old (mean=41 years). The course of therapy ranged from 30 to180 days (median=90 days). Conclusion: Based on the outcomes, there are many potential benefits to treatment of POD with sarecycline over the alternative tetracycline-class antibiotics. There is a need for more large-scale clinical studies evaluating treatment options for POD. Based on the efficacy and tolerability of sarecycline in large- scale acne studies, sarecycline may be an appropriate novel treatment option for POD and should be explored further.

Reflectance Confocal Microscopy of Adult Periorificial Dermatitis: A Case Report.

Periorificial dermatitis (PD) is an inflammatory disorder of the facial skin that mainly occurs around the mouth and manifests as erythema, papules, pustules, scales and other lesions. Special attention is needed in the clinical diagnosis of PD to distinguish it from acne, seborrheic dermatitis (SD), granulomatous rosacea (GR), sarcoidosis and childhood granulomatous periorificial dermatitis (CGPD). We used reflectance confocal microscopy (RCM) images of a patient with PD to assist in the diagnosis of PD. RCM of PD showed slight oedema of the spinous layer. Numerous dendritic cells, scattered hair follicular keratotic plugging and hair follicle dilatation were observed. The dilation and congestion of superficial dermis blood vessels, an increasing vascular density and accelerated blood flow, and a greater abundance of infiltrated inflammatory cells were also detected.

Childhood granulomatous periorificial dermatitis in 31 Chinese children successfully treated with oral roxithromycin.

Data regarding the treatment of childhood granulomatous periorificial dermatitis (CGPD) using oral therapies are limited. This study included 31 Chinese children with CGPD treated with oral roxithromycin. After 12 weeks of treatment, 90.3% of the patients recovered, and there were no severe adverse effects. Our results suggest that oral roxithromycin is an effective and safe treatment for CGPD.

Clinical Characteristics of 9 Adult Patients with Granulomatous Periorificial Dermatitis and Comparison with Childhood Granulomatous Periorificial Dermatitis.

To our knowledge, there have been no previous reports of granulomatous periorificial dermatitis (GPD) in adult patients in contrast to childhood GPD (CGPD). We report cases of 9 adult patients with GPD with regards to the clinical and histopathological characteristics and their management. GPD in adults may be an entity that is actually underdiagnosed, especially in middle-aged females. It is a benign disorder, albeit requiring a relatively long-term treatment. Unlike CGPD, GPD in adults is frequently accompanied by pruritus with predilection for the eyelid and should be treated initially with oral medication.

Features of the Skin Microbiota in Common Inflammatory Skin Diseases.

Many relatively common chronic inflammatory skin diseases manifest on the face (seborrheic dermatitis, rosacea, acne, perioral/periorificial dermatitis, periocular dermatitis, etc.), thereby significantly impairing patient appearance and quality of life. Given the yet unexplained pathogenesis and numerous factors involved, these diseases often present therapeutic challenges. The term "microbiome" comprises the totality of microorganisms (microbiota), their genomes, and environmental factors in a particular environment. Changes in human skin microbiota composition and/or functionality are believed to trigger immune dysregulation, and consequently an inflammatory response, thereby playing a potentially significant role in the clinical manifestations and treatment of these diseases. Although cultivation methods have traditionally been used in studies of bacterial microbiome species, a large number of bacterial strains cannot be grown in the laboratory. Since standard culture-dependent methods detect fewer than 1% of all bacterial species, a metagenomic approach could be used to detect bacteria that cannot be cultivated. The skin microbiome exhibits spatial distribution associated with the microenvironment (sebaceous, moist, and dry areas). However, although disturbance of the skin microbiome can lead to a number of pathological conditions and diseases, it is still not clear whether skin diseases result from change in the microbiome or cause such a change. Thus far, the skin microbiome has been studied in atopic dermatitis, seborrheic dermatitis, psoriasis, acne, and rosacea. Studies on the possible association between changes in the microbiome and their association with skin diseases have improved the understanding of disease development, diagnostics, and therapeutics. The identification of the bacterial markers associated with particular inflammatory skin diseases would significantly accelerate the diagnostics and reduce treatment costs. Microbiota research and determination could facilitate the identification of potential causes of skin diseases that cannot be detected by simpler methods, thereby contributing to the design and development of more effective therapies.

Treatment of pediatric periorificial dermatitis with topical calcineurin inhibitor and topical/oral metronidazole.

Pediatric periorificial dermatitis is a papulopustular eruption found around the facial orifices in children. Although the treatment of the disease has been largely anecdotal and experience-based, studies have shown that topical calcineurin inhibitors, as well as other topical and oral antibiotics, such as metronidazole, can be effective treatment options. However, most of the studies with a sizable number of patients have been based on the Caucasian population. Herein, we evaluated the clinical efficacy of topical calcineurin inhibitors and topical/oral metronidazole in 24 Korean patients with pediatric periorificial dermatitis. The majority of the patients showed a complete response to treatment.

Oral Granulomatous Disease.

Granulomatous diseases are chronic inflammatory disorders whose pathogenesis is triggered by an array of infectious and noninfectious agents, and may be localized or a manifestation of systemic, disseminated disease. As in the skin, oral manifestations of granulomatous inflammation are often nonspecific in their clinical appearance. Thus, in the absence of overt foreign material or a recognizable infectious agent, identifying the underlying cause of the inflammation can be challenging. This article highlights various conditions known to induce granulomatous inflammation within the oral soft tissues.

Topical calcineurin inhibitors for pediatric periorificial dermatitis.

BACKGROUND: Data regarding the treatment of periorificial dermatitis with topical calcineurin inhibitors (TCI) in the pediatric population are limited. OBJECTIVE: To assess the clinical utility of TCI in pediatric patients with periorificial dermatitis. METHODS: A retrospective medical record review of all pediatric patients with periorificial dermatitis treated with TCIs was performed. Follow-up via telephone was performed to capture missing data. RESULTS: A total of 132 patients met the inclusion criteria. The median age at diagnosis was 4.2 years (interquartile range, 2.3-8.2). The median follow-up was 5.2 months (interquartile range, 2.1-11.7). Seventy-two patients had evaluable follow-up data. Of these, 48 (67%) patients were treated with TCI alone, 12 (16.7%) were treated with a combination of TCI and topical metronidazole, and 9 (12.5%) were treated with a combination of TCI and a systemic antibiotic. Complete response was noted in 68.8% of patients treated with TCI alone, in 75% of patients treated with TCI and metronidazole, and in 77.8% of patients treated with TCI and a systemic antibiotic. Adverse events were rare and mild in severity. CONCLUSION: Topical calcineurin inhibitors are an effective therapeutic option for pediatric patients with periorificial dermatitis and were well tolerated in this cohort.

Recalcitrant granulomatous periorificial dermatitis with good response to low-dose oral isotretinoin.

Granulomatous periorificial dermatitis is a clinical variant of periorificial dermatitis. We present the case of an 18-year-old girl with several reddish papular lesions in the perioral, perinasal, and periorbital regions unresponsive to conventional therapy. After 6 months of therapy with low-dose oral isotretinoin, the lesions fully remitted.

Head-and-neck dermatitis: Diagnostic difficulties and management pearls.

Head-and-neck dermatitis is a variant of atopic dermatitis (AD) often seen in children and is challenging to diagnose, as it frequently overlaps with other eczematous dermatoses. Successful head-and-neck dermatitis (HND) treatment requires identification of common triggers and clinical mimickers, such as airborne dermatitis, periorificial dermatitis, and steroid-induced rosacea. Head-and-neck involvement negatively impacts quality of life and is often harder to treat than other body parts, as long-term topical corticosteroid use carries higher risks for skin atrophy on the face. Heating and flushing associated with HND further exacerbate the itch-and-scratch-cycle and disrupt sleep. We aim to address diagnostic gaps, identify clinical mimickers, and share clinical pearls in managing HND, including cooling pillows, thermal water sprays, rice starch paper facial masks, and tips to minimize food and saliva-induced facial irritation.

[Granulomatous periocular eruption]. / Dermatite périoculaire granulomateuse.

BACKGROUND: Herein, we report a case of atypical periorificial dermatitis in a patient that had been receiving treatment for some time for atopic dermatitis. The specific feature of this rash was its periocular predominance with no perioral involvement, its clinical aspect and its histological picture evocative of sarcoidosis. PATIENTS AND METHODS: A 33-year-old man was being treated for a atopic dermatitis limited to the face and poorly responsive to dermal corticosteroids. Treatment was initiated with topical tacrolimus 0.1%. After 4 years, dependence on this treatment was noted, with daily application being needed to control the lesions. One year later, symmetric lesions were seen on the eyelids and periorbital regions; these were erythematous, micropapular and poorly delineated in a setting of oedema. Biopsy revealed epithelioid granulomatous inflammation, and, to a lesser degree, sarcoidal giant-cell features without caseous necrosis. Staging tests to identify systemic sarcoidosis were negative. Treatment with hydroxychloroquine at 400mg per day and discontinuation of topical tacrolimus resulted in complete remission of the lesions within 2 months. Hydroxychloroquine was discontinued after 6 months, and no relapses had occurred after 2 years of follow-up. DISCUSSION: Three diagnostic hypotheses may be posited for these granulomatous facial lesions. We opted for a diagnosis of granulomatous periorificial dermatitis despite the fact that exclusively periorbital involvement is rare (this condition is generally associated with perioral dermatitis). The second was that of pure cutaneous sarcoidosis, but the topography and clinical appearance of the lesions did not correspond to any of the cutaneous forms classically described. The third was that of tacrolimus-induced granulomatous rosacea, but the histological picture is different. CONCLUSION: The present case underscores the fact that a histological appearance of sarcoidosis on skin biopsy may be associated with perioral dermatitis.

Granulomatous Rosacea and Periorificial Dermatitis: Controversies and Review of Management and Treatment.

Granulomatous rosacea and periorificial dermatitis are common skin conditions affecting the face. This article examines the historical origin, causes, clinical presentation, and management strategies for these entities.

Childhood granulomatous periorificial dermatitis.

Childhood granulomatous periorificial dermatitis (CGPD), also known as facial Afro-Caribbean childhood eruption (FACE), is a distinctive granulomatous form of perioral dermatitis. It is a condition of unknown etiology, characterized by monomorphous, small, papular eruptions around the mouth, nose and eyes that histopathologically show a granulomatous pattern. It affects prepubescent children of both sexes and typically persists for several months but resolved without scarring. We report a 9 year-old girl with multiple, discrete, monomorphic, papular eruptions of 2-months duration on the perioral and periocular areas. Histopathological examination demonstrated upper dermal and perifollicular granulomatous infiltrate.
