Acne vulgaris is the most common dermatological disease in the United States, affecting up to 85 percent of teenagers. While the American Academy of Dermatology has established guidelines regarding acne treatment in general, the variability among acne treatments, even within a given class, prevents establishment of a straightforward regimen. For example, moderate to severe acne is generally treated with an oral antibiotic, although several options are available-both across and within antibiotic classes. The aim of this review is to report the efficacy and safety data available for commonly prescribed oral antibiotics. While there are currently no data to support superiority of one drug over another, there are substantial differences in safety profiles and brand-specific features that may make one antibiotic preferable over another.

Our understanding of the pathogenesis of acne vulgaris is still evolving. It is known that multiple factors impact acne pathophysiology, including genetic, hormonal, inflammatory, and environmental influences. Because of its implications in many of these factors, diet has been a part of the acne discussion for decades. Several studies have evaluated the significance of the glycemic index of various foods and glycemic load in patients with acne, demonstrating individuals with acne who consume diets with a low glycemic load have reduced acne lesions compared with individuals on high glycemic load diets. Dairy has also been a focus of study regarding dietary influences on acne; whey proteins responsible for the insulinotropic effects of milk may contribute more to acne development than the actual fat or dairy content. Other studies have examined the effects of omega-3 fatty acid and γ-linoleic acid consumption in individuals with acne, showing individuals with acne benefit from diets consisting of fish and healthy oils, thereby increasing omega-3 and omega-6 fatty acid intake. Recent research into the effects of probiotic administration in individuals with acne present promising results; further study of the effects of probiotics on acne is needed to support the findings of these early studies. In this review, we discuss the current evidence regarding the diets of US patients with acne and how they may impact acne and acne treatment.

Background: Rosacea is a chronic skin condition characterized by primary and secondary manifestations affecting the centrofacial skin. The primary diagnostic phenotypes for rosacea are fixed centrofacial erythema with periodic intensification, and phymatous changes. Major phenotypes, including papules and pustules, flushing, telangiectasia, and ocular manifestations, may occur concomitantly or independently with the diagnostic features. The phenotypes of rosacea patients may evolve between subtypes and may require multiple treatments concurrently to be effectively managed. We report the proceedings of a roundtable discussion among 3 dermatologists experienced in the treatment of rosacea and present examples of rosacea treatment strategies that target multiple rosacea symptoms presenting in individual patients., Methods: Three hypothetical cases describing patients representative of those commonly seen by practicing dermatologists were developed. A roundtable discussion was held to discuss overall and specific strategies for treating rosacea based on the cases., Results/discussion: With few exceptions, the dermatologists recommended combination therapy targeting each manifestation of rosacea for each case. These recommendations are in agreement with the current American Acne and Rosacea Society treatment guidelines for rosacea and are supported by several studies demonstrating beneficial results from combining rosacea treatments., Conclusions: Rosacea is an evolving condition; care should take into account all clinical signs and symptoms of rosacea that are present in an individual patient, understanding that symptoms may change over time, and utilize combination therapy when applicable to target all rosacea symptoms.

Background: A novel tretinoin 0.05% lotion formulation has been shown to be efficacious and well-tolerated, and especially effective in adult female acne patients. While it is perhaps counter-intuitive that patients with more severe disease would show clinically significant improvement with topical monotherapy, topical retinoids have been shown to offer realistic treatment options in these patients. Objective: To evaluate the safety and efficacy of once-daily tretinoin 0.05% lotion in adult females with moderate or severe acne. Methods: Post hoc analysis of two multicenter, randomized, double-blind, vehicle-controlled phase 3 studies. Adult females (>=18 years of age) with moderate (N=551) and severe (N=55) acne were randomized (1:1) to receive tretinoin 0.05% lotion or vehicle, once-daily for 12 weeks. Efficacy assessments included changes in baseline inflammatory/noninflammatory lesions, treatment success (at least 2-grade reduction in Evaluator’s Global Severity Score [EGSS] and clear/almost clear) and quality of life (QoL) using the validated Acne-QoL questionnaire. Safety, adverse events (AEs), and cutaneous tolerability were evaluated throughout. Results: At week 12, efficacy in adult females with moderate acne (EGSS=3) treated with tretinoin 0.05% lotion was significantly greater than that reported with vehicle. Mean percent reduction in inflammatory and noninflammatory lesion counts was 58.5% and 55.5% respectively compared with 50.3% and 39.8% with vehicle (P=0.039 and P<0.001). Treatment success was achieved by 25.4% of subjects by week 12, compared with 15.4% with vehicle (P=0.006). Tretinoin 0.05% lotion was numerically more effective in adult females with severe acne (EGSS=4). Mean percent reduction in inflammatory and noninflammatory lesion counts was 59.0% and 58.8% respectively (compared with 53.5% and 45.5% with vehicle), and treatment success was achieved by 17.9% of subjects (compared with 4.5% with vehicle), with 46.6% of subjects achieving at least a 2-grade improvement in EGSS by week 12. Quality of life improvements with tretinoin 0.05% lotion were significant compared with vehicle in adult females with moderate acne (except role-social), but not in severe acne (probably due to the group size). The majority of AEs were mild and transient; more frequently reported in the moderate acne population where application site pain (2.9%), and application site dryness (5.0%) were the most common, compared with one report (4.5%) of application site pain and dryness in the severe acne population. Local cutaneous safety and tolerability assessments were generally mild-to-moderate and improved by week 12. Limitations: The number of severe subjects enrolled in the studies was considerably less than the number of subjects with moderate acne, and the studies were not powered to demonstrate a difference in efficacy based on acne severity. Conclusions: Tretinoin 0.05% lotion was significantly more effective than vehicle in achieving treatment success and reducing inflammatory and noninflammatory lesions in adult females with moderate acne, with notable improvements in treating adult females with severe acne. It was well-tolerated, and all treatment-related AEs were mild or moderate. J Drugs Dermatol. 2019;18(11):1147-1154.

During fall 2008, 10 roundtable discussions involving 70 practicing dermatologists and a physician assistant were conducted across the United States to address patient considerations and treatment strategies for acne vulgaris. A case study format was used to initiate discussion. This supplement is based on the issues raised during the roundtable discussions and at a final working session among the authors where suggestions, trends, and the consensus from each of the 10 roundtable discussions were reviewed regarding published, evidence-based recommendations for treating acne vulgaris. Effective treatment of acne vulgaris can prevent adverse emotional sequelae and physical scarring. We hope that the information presented herein will help guide our colleagues in improving the care of patients with acne vulgaris.

The isotretinoin registry has arrived. It has a lofty goal of preventing all isotretinoin pregnancies. How we got to this point and what the registry means to prescribers and patients have many dermatologists confused and concerned. Will it be burdensome, will it preclude the use in most offices of this most important drug? Will it breed a new group of "isotretinologists" who are willing to take on the challenge? This article endeavors to answer these questions and to put most concerns at rest. The new system seems ultimately to have few changes compared to the risk management program we are already (technically) following. The difference is that compliance with all the rules will be monitored and mandatory. The system seems user friendly, is accessible to the computer-savvy as well as those of us still addicted to telephone, and may well turn out to be much fuss made over minimal hassle. What is clear is that this is likely our last chance to save this wonderful drug from oblivion. It is time for dermatologists to step to the plate and do what is in the best interest of their patients.

Acne is the most common problem that presents to dermatologists. Because it causes visible disfiguring of the face, it produces a great deal of embarrassment, frustration, anger, and depression in patients. In addition, acne is most common in adolescence and young adulthood, a time when patients are least capable of coping with additional stress. As a result, it is virtually impossible to separate acne from psychiatric disturbances. Some patients are severely affected and require more than just acne therapy. Dermatologists need to become more adept at diagnosing and treating causative, concomitant, and resultant psychiatric disturbances in patients with acne. This article is intended to highlight the scope of the problem, identify at-risk patients, and help dermatologists assist patients with both their acne and their psychologic response to it.
