Joint Sponsorship This activity has been planned and implemented in accordance with the Essential Areas and Policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint sponsorship of the University of Louisville School of Medicine Continuing Health Sciences Education (CHSE) and Skin Disease Education Foundation, an Elsevier business. CHSE is accredited by the ACCME to provide continuing education for physicians. Designation Statement CHSE designates this educational activity for a maximum of 2.0 AMA PRA Category 1 Credit(s)™. Physicians should only claim credit commensurate with the extent of their participation in the activity. 2 Statement of Professional Practice Gap(s) Untreated or ineffectively managed acne vulgaris is associated with important physical and psychosocial sequelae. The wide range of topical and systemic treatments allows clinicians to choose a regimen that is appropriate for each patient. Further, with appropriate treatment, acne can be successfully managed in almost every case. The articles in this supplement provide an update on the epidemiology, pathophysiology, medical and psychosocial impact, and treatment of acne vulgaris in pediatric patients. As much of the most recent new information on acne concerns an emerging subgroup—that is, children between about 8 and 11 years of age—evidence and insights about younger patients are presented and discussed. Clinicians who provide health care to pediatric patients with acne must have the latest clinical data and knowledge to individualize their patients’ care. Learning Objectives Upon completion of this activity, participants will be better able to: • Assess and classify acne vulgaris in pediatric patients. • Describe the topical and systemic medications available and suitable for use in pediatric patients with acne. • Determine the type of medication and route of delivery appropriate for individual patients, based on age, severity of disease, and other factors. • Counsel patients and parents regarding the management of the disease and review strategies for coping with acne. Disclosure As a sponsor accredited by the ACCME, CHSE must ensure balance, independence, objectivity, and scientific rigor in all its sponsored educational activities. All faculty participating in this CME activity were asked to disclose the following: Facing the Challenge of Acne Vulgaris in Pediatric Patients Volume 29, Number 2S June 2010 Introduction Introduction R ecently, a panel of experts convened during the Skin Disease Education Foundation’s 34th Hawaii Dermatology Seminar to discuss acne vulgaris in pediatric patients. The goal of this panel discussion was to review the medical literature and clinical experience to provide clinicians with an update on the epidemiology, pathophysiology, medical and psychosocial impact, and treatment of acne vulgaris in pediatric patients. Although new evidence and insights are available in these areas that apply to people with acne at any age, a great deal of the newest information refers to the condition in younger pediatric patients, those younger than the typical “adolescent acne patient” who is between 12 and 18 years of age. Acne is commonly observed in healthy children from 8 through 11 years of age in increasing numbers. This condition is to be distinguished from the lesions found in neonatal acne and acne that occurs in patients with various pathologic causes of premature adrenarche (a cause of precocious puberty). In these articles, the authors discuss the evidence concerning the epidemiologic trends and underlying causes for this downward shift in acne age of onset, as well as approaches to recognizing the severity and type of acne and treating the condition at any age. Furthermore, in all age groups, the treatment regimens chosen must be matched to disease se- verity, and the effectiveness of those regimens must be monitored, assessed, and adjusted as needed. In younger patients, in particular, careful follow-up is key to optimal management because in many children, acne has a tendency to worsen with pubertal maturation. Thus, in patients in the 8- to 11-year-old subgroup, changes in the effectiveness of medications over time are more likely to occur than in older patients, whose disease is more likely to stabilize once an effective therapy has been identified (assuming consistency of compliance with the regimen). In addition, in younger patients with acne, the psychosocial impact of the condition also tends to vary over time. For example, mild-to-moderate acne may not be especially bothersome to many 9-year-old children but may become more of an issue when they enter middle school. Clinicians who provide health care to children between 8 and 18 years of age—whether in dermatologic, pediatric, or primary care settings—already are aware of the need for appropriate assessment and treatment of younger patients with acne. The authors hope that these articles will provide information of immediate practical use, and at the same time provide insight into future research that may yield clinically applicable evidence over the next several years. 1.Names of proprietary entities producing Johnson & Johnson, Quinnova, Ranbaxy, health care goods or services—with the Shire, Stiefel, Triax, and Valeant.

Webster, MD, PhD¶ The demographic profile of facial acne vulgaris has changed during the past several decades; 12 years of age is no longer the low end of the “normal” range for onset of acne. The available epidemiologic evidence raises more questions than it answers regarding the etiology of this downward shift. More study is needed to clarify whether the trend toward an earlier onset of puberty in the United States has influenced the clinical picture of acne. Additional research will help advance understanding of the spectrum of pathophysiologic changes in acne in younger pediatric patients and whether it varies from that found in individuals in whom the onset of acne occurs at approximately 12 years of age or later. Semin Cutan Med Surg 29:2-4 © 2010 Elsevier Inc. All rights reserved. I n the past several years, clinicians have noted an earlier onset of acne—that is, the appearance of acne in patients as young as 8 or 9 years of age. This clinical observation has been supported by epidemiologic evidence that suggests that the average age of the onset of puberty has decreased. *Rady Children’s Hospital, UCSD School of Medicine, San Diego, CA. †University of Louisville, Louisville, KY. *Rady Children’s Hospital, UCSD School of Medicine, San Diego, CA. ‡Yardley Dermatology †University of Louisville, Louisville, KY.

The purpose of the study was to assess trends in pubertal onset and the relationship of those trends to body mass index in boys. The investigators showed that the onset of puberty occurred significantly earlier during 2006-2008 (with a mean age of 11.66 years) than in 1991-1993 (mean age, 11.92 years). A number of articles have been published considering whether and why sexual maturation may be occurring earlier in the United States,2–11 but the conclusions regarding the US data have been mixed. The National Health and Nutrition Examination Surveys and other surveys have not clearly demonstrated whether pubertal age is decreasing over time, nor have they established whether socioeconomic and racial factors may affect this. Nevertheless, epidemiologic evidence does support the impression of many clinicians—including the authors—that the average age of puberty has decreased.7,9 Some propose that nutrition may be one explanation for earlier onset of puberty in the United States—that is, that either better nourishment accounts for the change, or that obesity contributes to either a change in pubertal status or a change in acne presentation.

Fowler, Jr, MD, Sheila F. Friedlander, MD,* Diagnosis and Evaluation of Acne Moise L. Levy, MD, and Guy F. Webster, MD, PhD † ‡ § Lawrence F. Eichenfield, MD,* Joseph F. Fowler, Jr, MD,† Sheila F. Friedlander, MD,* Moise L. Levy, MD,‡ and Guy F. Webster, MD, PhD§ The diagnosis of acne usually can be made on the basis of a history and physical examination. The differential diagnosis includes a variety of possible causes and differs according to age group (mid-childhood, 1-7 years of age; pre-, peri-, and early pubertal, 8-11 years of age; pubertal/postpubertal, >12 years of age). The presentation of acne in adolescents tends to include both noninflammatory and inflammatory lesions, whereas in younger patients noninflammatory comedones are typical. Keratosis pilaris affecting the cheeks sometimes may be confused with early acne vulgaris. Screening tests, particularly bone age, may be considered to support the clinical diagnosis in younger children. Further testing usually is not indicated unless patients show signs of virilization. Semin Cutan Med Surg 29:5-8 © 2010 Elsevier Inc. All rights reserved. T he presentation of acne vulgaris differs according to the age at onset. The signs and symptoms of acne vulgaris in patients 12 years of age and older has been thoroughly and well described and in most cases are readily recognized. Often these patients have both noninflammatory lesions (comedones) and inflammatory lesions (papules, pustules, and/or cystic lesions). *Rady Children’s Hospital, UCSD School of Medicine, San Diego, CA. *Rady Children’s Hospital, UCSD School †University of Louisville, Louisville, KY. of Medicine, San Diego, CA. †University of Louisville, Louisville, KY. ‡Baylor College of Medicine, Houston, TX. ‡Baylor College of Medicine, Houston, TX. §Jefferson Medical College, Philadelphia, PA. §Jefferson Medical College, Philadelphia, PA.

In contrast, acne in younger patients typically is noninflammatory, characterized by comedones on the nose, midface, and forehead (Fig. 1). The number of lesions ranges from just a few to 100 or more. In a study of a topical medication, Eichenfield and colleagues1 found that the median number of lesions in 8- to 11-year-old children enrolled in their clinical trial was between 50 and 60. In more than one half of these patients, the lesions were located on the forehead or forehead plus other facial areas; approximately 4 in 10 children had comedonal lesions on the nose or nose plus other facial areas.

In some cases, further diagnostic testing is indicated, and referral to a pediatric endocrinologist is recommended if a patient has any signs of virilization. Although standardized assessment tools are not yet available for routine clinical use, clinicians must nevertheless qualitatively assess the severity of acne.

Physical comorbidities associated with classic acne are quite rare. Often more difficult to detect and measure are the short- and long-term psychosocial consequences of acne. These frequently are devastating and life-altering and in some cases are life-threatening. Semin Cutan Med Surg 29:9-12 © 2010 Elsevier Inc. All rights reserved. A cne once was widely considered more a rite of passage than a disease. Over time, awareness of the potentially destructive impact of acne increased, along with the development of more effective drugs to treat it. The medical impact generally includes scarring of the face, chest, and back; persistent alterations in pigmentation; and physical discomfort. Fortunately, physical comorbidities associated with acne vulgaris are rare; the possibilities include acne fulminans and the SAPHO syndrome (ie, synovitis, acne, pustulosis, hyperostosis, and osteitis). *Yardley Dermatology Associates, Yardley, PA. *Yardley Dermatology Associates, Yardley, PA. †Jefferson Medical †Jefferson Medical College, College,Philadelphia, Philadelphia,PA.

E-mail: An impressive array of effective and safe drugs now is available to clinicians, giving them the means to alleviate the short-term burden of acne lesions in patients as well as tools to prevent the long-term problem of physical scarring. Appropriate medical management also can help prevent common psychosocial sequelae, which may include decreased self-esteem, depression, academic impairment, social withdrawal, decreased employability, and social stigmatization. The Scopeof of The Scope PsychosocialSequelae Sequelae Psychosocial Acne can be responsible for long-term psychological damage that can affect the ability to optimally love, work, and play, with acne presenting at earlier ages and commonly continuing into adult years. It is well documented in the pediatric literature that clinicians are seeing an earlier onset of acne (see “Acne Epidemiology and Pathophysiology,” page 42), so the duration of disease may be longer for some patients.1 Acne vulgaris can lead to short- and long-term difficulties with depression, anxiety, anger, and impairment in self-image.2 Functionally, it can lead to difficulties with school, play, and interpersonal relationships. Individuals with acne—regardless of age—are more likely to experience discrimination in all aspects of life and often are subjected to ridicule and rejection by their peers. Sometimes clinicians and caregivers assume that mild acne is not emotionally important. For a great number of patients, this is true. However, some patients experience severe psychological effects from comedonal or mild inflammatory disease.2 In these patients, acne may be mild in clinical grading but severe in psychological impact. Conversely, some patients with severe disease—markedly inflammatory acne, pigmentary alteration, obvious signs of scarring—seem to cope without a great deal of emotional burden. Thus, clinical severity of acne may not always be a good predictor of psychological impact.

All rights reserved. doi:10.1016/j.sder.2010.04.005 12 Even in younger pediatric patients with mild disease—many of whom are not particularly bothered by a relatively small number of comedones—treatment is indicated when a clinician identifies any current evidence or potential for physical scarring. At the very least, younger patients with mild acne—and their parents—should receive therapy in the form of education about the condition, signs and symptoms to note that should prompt a visit with a clinician, and proper skin care that will provide a foundation for acne treatment in the likely event that it is needed in the future. Regardless of the severity (or mildness) of acne, treatment certainly is indicated in the presence of, or when there is risk for, psychological morbidity. The type of treatment chosen to initiate therapy should be determined by the severity of the acne, regardless of the patient’s age. Factors to consider when making an assessment of disease severity are the extent of affected areas (mild, moderate, or severe), the types of lesions (noninflammatory comedones; inflammatory papules, pustules, nodules), and the presence or absence of scarring and/or dyspigmentation. A number of treatment guidelines have been published, reflecting a broad consensus regarding an approach that begins with topical treatment whenever appropriate, systemic therapy whenever necessary, and limiting use of antibiotics— oral or topical—whenever possible.1-3 TopicalTherapy Therapy Topical A broad variety of topical treatments are available for initial therapy of 1).1).

When acne is very mild, involving a small number of lesions, a benzoyl peroxide product can often be effective for initial therapy. For mild-to-moderate comedonal acne, there is general agreement that treatment should be initiated with a topical retinoid. For significant or severe comedonal disease, retinoid therapy should be used, either alone or in combination with another agent. Topical retinoids (tretinoin, adapalene, or tazarotene) represent the cornerstone of therapy for almost all patients with acne vulgaris1 and are effective and safe, with good tolerability in both younger (8-11 years) and older (12-18 years) subgroups of pediatric patients. Matiz and colleagues4 completed an open-label, 12-week study of the efficacy, safety, and tolerability of 0.04% tretinoin gel in 40 patients between 8 and 12 years of age (mean age, 10.7 years). The medication was provided in a pump dispenser, and dosage instructions were determined by the number of pumps (patients were told to apply 2 pumps of the medication once a day, at night). All the subjects had mild-tomoderate acne. The primary efficacy end point was the change in the Evaluator’s Global Severity Score at week 12; the secondary efficacy end point was the Investigator’s Global Evaluation at week 12. Evaluations were performed at baseline and at weeks 3, 6, and 12. At week 12, the mean Evaluator’s Global Severity Score showed significant improvement over baseline (P � 0.001). Safety was evaluated by signs and symptoms of cutaneous irritation (erythema, dryness, peeling, burning/stinging, and itching). All patients had at least mild skin irritation, but no Facing the Challenge of Acne Vulgaris in Pediatric Patients patient discontinued because of side effects (1 patient discontinued because of worsening acne). These findings support those reported by Jorizzo and colleagues,5 who studied the use of tretinoin microsphere 0.04% gel in a group that included patients as young as 11 years of age. SystemicTherapy Therapy Systemic Systemic therapy is less commonly needed in younger patients with acne than in older adolescents, but only because most patients in the younger group tend to have milder, noninflammatory disease. Systemic therapy should be considered and used in patients 8 to 11 years of age—without hesitation—when needed. This includes the use of oral antibiotics as first-line therapy, along with a topical retinoid, in patients with inflammatory acne and in those with scarring acne regardless of disease severity. The oral antibiotics most commonly used for treating acne are minocycline and doxycycline.6 (Tetracycline and erythromycin, once the most frequently prescribed agents for acne, are used less commonly today because of increased P acnes resistance to these drugs.6) Antibiotics in the tetracycline class can be used in children as young as 8 years of age but should be avoided in younger patients because of the potential for adverse effects on the bones and teeth. In cases of refractory acne, when 3 to 4 months of treatment with appropriate combinations of topical retinoids and systemic antibiotics have not controlled the disease, other systemic therapy may be considered. There is broad experience with oral contraceptives being used for contraception in teenagers; therefore, so most clinicians feel 13 Table 2 Combination Retinoid-Based Therapy for Acne Table 2 Combination Retinoid-Based Therapy for Acne The combination of a topical retinoid and antimicrobial agent remains the preferred approach for almost all patients with •acne.

Expert opinions vary on when it is safe to initiate hormonal therapy in younger girls, but there is general agreement that hormonal therapy should not begin until at least 1 year after menarche. The current standard for prescribing hormones for contraception is that a gynecologic evaluation and Papanicolaou test are not necessary if the patient is not sexually active. In general, pediatric dermatologists have adopted a similar approach when using these agents for treating acne. The patient and her family should be asked about risk factors for contraceptive use, including smoking, a history of migraine headaches or cardiac or thromboembolic disease, or a strong family history of thromboembolic disease. Isotretinoin may be used (albeit as an off-label use) for any patient with severe, refractory acne, including patients between 8 and 11 years of age. Appropriate counseling and standard precautions observed with adolescents apply to these younger children as well. ManagingFactors Factors Managing That AffectTolerability Tolerability That Affect An issue that most clinicians encounter frequently is the variable tolerability of topical agents. For example, benzoyl peroxide is associated with a low rate of true contact allergy, whereas a substantial number of patients who use some benzoyl peroxide products may complain of dryness and/or irritation, without true allergy. Many patients may have no such difficulties with other benzoyl peroxide products—including benzoyl peroxide–antibiotic and benzoyl peroxide–retinoid combination therapy. Similarly, topical retinoids often are well tolerated by younger, prepubertal patients, particularly when less-irritating formulations are used in accordance with appropriate instruction. To improve tolerability of topical agents that tend to be drying or irritating early in the course of treatment, gradual dosing can be considered. For example, the use of a retinoid twice a week or every other day for the first few weeks of the regimen may be helpful; after this time, daily use can be instituted. Moisturizers can also be used to decrease irritation. The active ingredient of a topical preparation is a very important component of efficacy, but the vehicle also is an 14 important component of drug tolerability. These factors, in turn, affect whether the medication works—not just because of its efficacy but also because of any impact it may have on the use of and compliance with the medication regimen. Although no differences may exist between generic topical medications in the active ingredient, a difference in the vehicle means that the medication is different. As a result, a patient may have a different response (or lack of response) to the same medication in a different vehicle, and less-irritating products may be more likely to “work” because the patient is more compliant with therapy. In addition, any patient’s skin care routine can have a great effect on the tolerability of topical medications. This variable is too often overlooked when tolerability is a particular concern with a medication (as in the examples cited above) or with an individual patient. This is a variable that is always considered in clinical trials of topical agents—the investigators specify or proscribe certain activities or exposure to certain substances or products for the duration of the study. For example, researchers specify how facial cleansing is to be done, and with what products, as well as whether a moisturizer can be used and, if so, what type. Patients and caregivers should understand that the goal of washing the skin is not to scrub away acne; instead, the goal is to cleanse and prepare the skin for accepting and tolerating the topical medication that will be applied. Overzealous washing and the use of astringent cleansers do not prevent future acne lesions but only increase the risk for irritation and reduced tolerance of the medication. Long-TermMaintenance Maintenance Long-Term Systemic therapy with oral antibiotics can be very helpful in bringing moderate-to-severe disease under control. However, once adequate control is achieved, it is reasonable to use regimens that minimize antibiotic exposure. Many patients do well with subsequent use of a topical regimen with a combination retinoid plus antibiotic or retinoid plus benzoyl peroxide combination (Table 2 lists available retinoid-based agents for acne). Maintenance therapy with topical retinoids or retinoid combinations may obviate the need for long-term, systemic antibiotics.7 Facing the Challenge of Acne Vulgaris in Pediatric Patients ly at th n. amin ees ge nd he n. er hal o- nt ed 16 Conclusions Conclusions Conclusions Early-onset acne appears to be occurring more frequently Early-onset to beand occurring more Disease frequently and warrantsacne earlyappears counseling intervention. at and age warrants counseling and intervention.
