Abstract
Allergic contact hypersensitivity reactions of the oral mucosa pose a significant medical concern for some patients. Oral hypersensitivity reactions can result from a vast number of allergenic chemicals, but occur commonly from dental materials, flavorings, and preservatives. Clinical presentation is varied and often overlaps with other oral conditions, complicating their diagnosis and management. The most common clinical entities associated with oral hypersensitivity reactions are oral lichenoid reactions and allergic contact cheilitis. In addition to reviewing these conditions and their most common corresponding allergens, this article summarizes the pathogenesis of oral hypersensitivity reactions and addresses patch testing pearls.

Abstract
Allergic contact dermatitis in the pediatric population is more common than previously recognized, with recent prevalence estimates of positive patch test reactions in the range of 14-70% of children patch tested. The aim of this study was to confirm the prevalence of clinically relevant allergic contact dermatitis in children at two referral centers and determine the most common contact allergens. We performed a retrospective case series analysis of 65 symptomatic children (35 girls and 30 boys) aged 1-18 years old who were patch tested over a 5-year period for recalcitrant dermatitis. Positive patch test reactions were noted in 54 of the 65 children (prevalence rate of 83%) to 80 different allergens. Fifty children (77%) had positive reactions which were determined to be of "definite" or "probable" current clinical relevance. We conclude that the diagnosis of allergic contact dermatitis to specific relevant allergens is common in children referred for patch testing and that contact allergy should be considered in all children with recalcitrant dermatitis. With this article, we review the literature and present a US based study regarding the clinical relevance of positive patch test reactions in children.

Abstract
Allergic contact dermatitis is now known to be a common problem in pediatric populations, accounting for up to 20% of all dermatitis seen in children. Seminal studies conducted over the past decade have demonstrated a prevalence rate in the range of 25% to 60% of children referred for epicutaneous patch testing. This patch test procedure is generally accepted as the gold standardin vivo technique to diagnose allergic contact dermatitis. However, the overwhelming majority of research studies to date have been conducted on adult populations. Increasingly, pediatric patients are undergoing patch test procedures with techniques that have been standardized and optimized almost exclusively in adults. With this article, we hope to emphasize common misconceptions and pitfalls encountered with this approach. In addition, we hope to stimulate research interest in this field so as to determine the optimum patch test conditions and techniques for children.

Abstract
We report two cases of focal preauricular dermal dysplasia and review the available literature. Focal preauricular dermal dysplasia is a form of aplasia cutis congenita in which atrophic skin lesions occur in a stereotypical bilateral distribution in the preauricular region. Although focal preauricular dermal dysplasia and membranous cutis aplasia of the scalp share clinical similarities, focal preauricular dermal dysplasia represents a form of aplasia cutis congenita that is not typically associated with extracutaneous anomalies.

Abstract
A 45-year-old woman presented in October 2005 with a history of an eruption involving her scalp and face, including her eyelids and behind her ears. The eruption began at the end of August. It flared after she used a calming moisturizer containing feverfew (Tanacetum parthenium). A second patient, a 25-year-old woman, presented complaining of a 1-month history of an eruption around the eyes that started after she began using a moisturizer containing feverfew. Both patients were patch-tested with the North American Contact Dermatitis Group series, cosmetic and plant series, and their own skin care products. Patient 1 had a + reaction to sesquiterpene lactone mix, a + reaction to Compositae mix, a + reaction to parthenolide, a + reaction to Tanacetum vulgare, and a + reaction to the calming moisturizer. Patient 2 had + reactions to sesquiterpene lactone, Compositae mix, and the same calming moisturizer. It is thought that both of these eruptions are a result of contact dermatitis from the Compositae plant family.

Abstract
Considering the widespread use of colophony-containing epilating products and the frequency of sensitization to colophony, it is somewhat surprising that reports of allergic contact dermatitis from these products are so infrequent. Reactions to colophony can be severe, and they may present even after initial exposure (primary sensitization). Consequently, health care practitioners should be aware of potential colophony-induced allergic contact dermatitis in patients exposed to epilating products. Patch testing with commercially available colophony unmodified rosins often fails to detect reactions to the modified-rosin derivatives found in the actual epilating products. Therefore, the evaluation of colophony allergy may require testing with the patient's own products as well as additional modified colophony rosins. We describe a case of allergic contact dermatitis caused by colophony found in an epilating product.

Abstract
PURPOSE OF REVIEW The following paper reviews the recent literature pertaining to allergic contact dermatitis in the pediatric population. RECENT FINDINGS Allergic contact dermatitis may affect as many as 20% of the pediatric population. Recent studies implicate the following chemicals as the most common causes: nickel, topical antibiotics, preservative chemicals, fragrances and rubber accelerators. Several less common, but emerging, allergens have also been reported recently, including para-phenylenediamine in henna tattoos, cocamidopropyl betaine in 'no tears' shampoos and cleansers, and disperse dyes in clothing materials. Allergic contact dermatitis occurs less frequently in the first few months of life and increases in prevalence with increasing age. In the adolescent age group, females have significantly higher rates of allergic contact dermatitis on the face. This is likely explained by increased exposures to nickel in piercings and to preservative and fragrance chemicals in cosmetic products. SUMMARY The documented rates of allergic contact dermatitis in children are on the rise. This increased prevalence may be due to increased chemical exposures in this age group, better recognition by pediatricians and perhaps more widespread use of epicutaneous patch testing. This review outlines the basic pathophysiology, epidemiology and clinical manifestations of allergic contact dermatitis in children.

Abstract
The attitudes of patients toward resident participation in a university-based dermatology outpatient clinic were evaluated. Of 206 patients asked to participate, 191 patients completed the self-administered questionnaire (92.7%). The overwhelming majority of patients (99.5%) were satisfied (81.8% "very satisfied" and 17.7% "satisfied") with the resident's participation in their care. Many more patients expressed a willingness to allow residents to take histories (93.6%), perform physical examinations (87.2%), and counsel on preventive measures (74.5%), than to allow surgical excisions of skin cancers (19.7%), perform skin biopsies (43.6%), or prescribe medications (44.7%). Of respondents to the questionnaire, 83.2% self-reported an understanding of the difference between "resident" and "attending" physicians. However, only 31.3% (95% confidence interval 24.5-38.1) were able to broadly categorize the amount of training completed by dermatology residents. Dermatology resident participation in outpatient clinics is essential to quality dermatologic education. Consistent with the results of prior studies in other medical disciplines, our study demonstrated an overwhelming patient satisfaction with the participation of dermatology residents in their care.

Abstract
Rosacea is one of the most common conditions dermatologists treat. Rosacea is most often characterized by transient or persistent central facial erythema, visible blood vessels, and often papules and pustules. Based on patterns of physical findings, rosacea can be classified into 4 broad subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular. The cause of rosacea remains somewhat of a mystery. Several hypotheses have been documented in the literature and include potential roles for vascular abnormalities, dermal matrix degeneration, environmental factors, and microorganisms such as Demodex folliculorum and Helicobacter pylori. This article reviews the current literature on rosacea with emphasis placed on the new classification system and the main pathogenic theories. Learning objective At the conclusion of this learning activity, participants should be acquainted with rosacea's defining characteristics, the new subtype classification system, and the main theories on pathogenesis.

Abstract
Despite an incomplete understanding of the pathogenesis of rosacea, therapeutic modalities continue to expand. The principal subtypes of rosacea include erythematotelangiectatic rosacea, papulopustular rosacea, phymatous rosacea, and ocular rosacea. These phenotypic expressions are probably caused by divergent pathogenic factors and consequently respond to different therapeutic regimens. A subtype-directed approach to therapy is discussed in part II of this review. We provide an overview of the available topical, oral, laser, and light therapies in the context of these cutaneous subtypes, review the evidence that supports their use, and outline their therapeutic approach. Suggestions for future areas of study also are provided. Learning objective At the completion of this learning activity, participants should be familiar with the subtype-directed approach to therapy for rosacea including available topical, oral, laser, and light therapies.

Abstract
BACKGROUND Problems with statistical methods and reporting have been noted in articles published in dermatology journals. Conclusions presented in published reports may be misleading if based on inappropriate or misinterpreted statistical analysis. OBJECTIVE We sought to assess dermatology journal editors' policies and perceptions regarding statistical review of submitted manuscripts. DESIGN We mailed and e-mailed a questionnaire survey. PARTICIPANTS A total of 43 dermatology journal editors, representing 35 dermatology journals from the United States and abroad, participated in this study. RESULTS In all, 32 editors (74.4%), representing 30 journals (85.7%), returned questionnaires. A total of 24 editors (75%) reported having requested statistical reviews on less than 5% of published manuscripts containing original quantitative analysis (ie, excluding reviews and case reports), whereas 3 editors (9.4%) reported having requested statistical reviews on more than 75% of such manuscripts. Most editors reported requesting statistical reviews on a case-by-case basis either after initial favorable review by subject-matter (nonstatistical) reviewers (12 editors; 37.5%) or at the same time that subject-matter review was requested (6 editors; 18.8%). A total of 4 editors (12.5%) reported requesting statistical review for all manuscripts at the same time they are sent for subject-matter review. Another 10 editors (31.3%) said their journals had no general policy on statistical reviewing, and statistical review is almost never needed. For 15 editors (46.9%), ideal statistical reviewing policy was identical to their current policy, whereas 13 (40.6%) favored a more rigorous and 3 (9.4%) a less rigorous policy. CONCLUSIONS Dermatology journals infrequently perform statistical reviews of submitted manuscripts. Dermatology journal editors' statistical review policies range from no general policy to (most frequently) requesting reviews on a case-by-case basis to reviewing all submitted manuscripts. Many editors favor more rigorous statistical reviewing policies for their journals. Increased use of statistical reviewing may increase the reliability of conclusions published in dermatology journals.

Abstract
OBJECTIVES To determine the 12-month prevalence of hand dermatitis among massage therapists, to investigate a potential association between hand dermatitis and the use of aromatherapy products, and to study potential associations with other known risk factors for hand dermatitis. DESIGN Mailed survey. SETTING Philadelphia, Pa. PARTICIPANTS Members of a national massage therapy organization who live in the greater Philadelphia region. MAIN OUTCOME MEASURES Self-reported and symptom-based prevalences of hand dermatitis. RESULTS The number of respondents was 350 (57%). The 12-month prevalence of hand dermatitis in subjects was 15% by self-reported criteria and 23% by a symptom-based method. In multivariate analysis, statistically significant independent risk factors for self-reported hand dermatitis included use of aromatherapy products in massage oils, lotions, or creams (odds ratio, 3.27; 95% confidence interval, 1.53-7.02; P =.002) and history of atopic dermatitis (odds ratio, 8.06; 95% confidence interval, 3.39-19.17; P<.001). CONCLUSIONS The prevalence of hand dermatitis in massage therapists is high. Significant independent risk factors include use of aromatherapy products in massage oils, creams, or lotions and history of atopic dermatitis.

Abstract
The use of botanical extracts for their perceived therapeutic benefits has gained increased popularity in this country and abroad. In particular, tea tree oil (the extracted oil of Melaleuca alternifolia) has gained widespread use for its purported antimicrobial and therapeutic effects. In parallel with this increased use is an expanding series of reported adverse effects, including allergic contact dermatitis, systemic contact dermatitis, linear immunoglobulin A disease, erythema multiforme-like id reactions, and systemic hypersensitivity reactions. We present a review of tea tree oil with regard to its history, chemistry, purported medicinal uses, and possible adverse cutaneous effects.

Abstract
BACKGROUND Recent reports indicate that laser hair removal is most effective on anagen hairs. However, no published trials have examined laser epilation after hair cycle synchronization. OBJECTIVE To evaluate the potential for enhanced laser hair removal after the induction of telogen hairs into anagen by wax epilation. METHODS We identified four 2.5-cm square areas with equivalent hair length and density on the backs of 13 dark-haired white men. To induce typically telogen hairs into anagen, two areas on each patient were wax epilated. Two weeks later, one waxed area and one unwaxed area were treated with a long-pulsed alexandrite laser. One month after laser treatment, a subjective comparison was made based on hair density, length, and thickness. RESULTS In 12 of 13 patients, lasered areas that had been pretreated with wax epilation were clearer of hair as compared with areas that had been pretreated by shaving (P=0.0034). No significant difference was noted between waxed and unwaxed control areas that had not been laser treated (P=1.0). CONCLUSION Wax epilation 2 weeks before laser hair removal improves cosmetic outcomes at 1 month. This effect may be secondary to the recruitment and heightened sensitivity of early anagen hairs.
