Tinea capitis: An update.

Tinea capitis is an important superficial infection and affects children globally. A literature review was conducted to identify recent findings and the current understanding of this fungal infection. Here, we highlight updates on important aspects of tinea capitis including advances in dermatophyte detection and diagnosis and comparing these new methods to more traditional techniques.

Hand-foot-skin reaction related to use of the multikinase inhibitor sorafenib and hard orthotics.

Hand-foot-skin reaction is a distinct clinical condition arising in association with the use of multikinase inhibitors, including sorafenib. Because multikinase inhibitors are increasingly being used in children with cancer, recognition of this previously unfamiliar condition is of importance to pediatric dermatologists. We describe the diagnosis and successful treatment of a case of hand-foot-skin reaction in a child taking sorafenib for an unresectable desmoid tumor.

Pediatric psoriasis: Evolving perspectives.

Background/objectives: Childhood-onset psoriasis is a common skin disorder that has recently received increasing attention, particularly because of its significant medical, social, financial, and psychological burdens and its associated comorbidities. With limited data available and lack of standardized management guidelines for pediatric psoriasis, an expert panel desired to provide an updated critical overview and practical guidance for management of the affected population.

Methods: A panel of pediatric dermatologists with extensive experience in pediatric psoriasis defined and prioritized a core set of topics, performed an English-language literature review, prepared critical evaluations and presentations of topic areas, and carried out a consensus meeting and follow-up consensus manuscript.

Dietary Supplements, Isotretinoin, and Liver Toxicity in Adolescents: A Retrospective Case Series.

Isotretinoin is the most effective acne therapy available, but has the potential for a number of adverse side effects, including transaminitis. The iPLEDGE isotretinoin program recommends avoiding some herbals and supplements due to potential side effects. However, little is known about the effects of protein supplements on the liver, particularly in patients taking isotretinoin.

Evidence-based recommendations for the management of acne fulminans and its variants.

Background: Acne fulminans (AF) is a severe variant of inflammatory acne. It typically manifests as an explosive worsening and ulceration of skin lesions, and can be associated with systemic symptoms. However, there is a paucity of evidence-based information and no clear guidelines concerning the classification and treatment of AF.

Infantile Hemangiomas: An Updated Review on Risk Factors, Pathogenesis, and Treatment.

Infantile hemangiomas (IHs) are the most common vascular tumors in infants, appearing in early infancy and ultimately regressing with time. Clinical presentation may vary, with a minority of lesions causing impairment of vital function (e.g.

Pediatric Onychomycosis: The Emerging Role of Topical Therapy.

Fungal infection of the nails is an increasingly recognized disease in infants and children. However, it can be difficult to distinguish clinically from other nail dystrophies. In addition, many mistakenly believe that onychomycosis does not occur in childhood.

Emerging Issues in Adult Female Acne.

Acne vulgaris (acne) is a common affliction in adolescence and is a growing problem in adult women. Despite an increasing awareness of acne in the adult female population, there is a lack of good prospective studies assessing the severity, distribution, and differential response to treatment in this group. The long-held dogma that acne in adult women develops on the lower one-third of the face has been recently challenged, and here the authors critically review data from available literature.

Infantile hemangiomas, complications and treatments.

Infantile hemangiomas (IHs) are the most common vascular tumors of infancy. While the majority regress without the need for intervention, approximately 10%, often site dependent, can cause serious complications and require treatment. IH complications can be categorized as life threatening, obstructive, ulcerative or disfiguring.

Imaging Pediatric Vascular Lesions.

Vascular anomalies are commonly encountered in pediatric and dermatology practices. Most of these lesions are benign and easy to diagnose based on history and clinical exam alone. However, in some cases the diagnosis may not be clear.

Cutaneous infectious diseases: Kids are not just little people.

The changes in immune response that occur with age play a significant role in disease presentation and patient management. Evolution of the innate and adaptive immune systems throughout life, influenced partly by hormonal changes associated with puberty, plays a role in the differences between pediatric and adult response to disease. We review a series of manifestations of dermatologic infectious diseases spanning bacterial, viral, and fungal origins that can be seen in both pediatric and adult age groups and highlight similarities and differences in presentation and disease course.

Onychoheterotopia Due to a Traumatically Transplanted Nail in a Child.

Onychoheterotopia is a rare condition characterized by ectopic nail tissue growth. It is a digital mass that is commonly misdiagnosed. We describe a 6-year-old girl who presented with onychoheterotopia after trauma to the digit.

Antifungal therapy for onychomycosis in children.

Onychomycosis is a chronic infection of the nail unit, and its prevalence increases with age. Treatment options for children are similar to those for adults and include both oral and topical therapies. Oral agents, such as terbinafine, itraconazole, and fluconazole have been reported to have good efficacy and a low rate of side effects in children.

Onychomycosis: epidemiology, diagnosis, and treatment in a changing landscape.

Onychomycosis is an often overlooked and/or undertreated disease. This may be in part due to an under appreciation among both physicians and patients of its impact on quality of life and the potential for significant complications, from tinea corporis and cruris, to bacterial superinfection. Some health care providers are unaware of the effective low-risk treatments currently available.

A randomized, controlled trial of oral propranolol in infantile hemangioma.

Background: Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited.

Methods: We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months).

Beta blockers: an innovation in the treatment of infantile hemangiomas.

Infantile hemangiomas are benign vascular tumors seen in 4.5 percent of neonates and infants. While most infantile hemangiomas can be managed with active nonintervention, a subset of patients will require more aggressive management.

Atopic dermatitis and the stratum corneum: part 3: the immune system in atopic dermatitis.

Part 3 of this three-part review of atopic dermatitis and the stratum corneum barrier discerns how immune dysregulation, including upregulation of a TH2 inflammation pattern, augmented allergic sensitization, sustained wound healing inflammation, and impaired innate immunity, plays an integral role in the pathogenesis of atopic dermatitis. An increased understanding of the interdependence, polymorphisms, and dysregulations of epidermal barrier functions, including the stratum corneum permeability barrier, immune defense, and antimicrobial barriers, should provide further knowledge about the pathophysiological mechanisms that are clinically relevant and that contribute to the development of atopic dermatitis. Further understanding of these mechanisms should lead to newer therapies that target specific pathogenic components of atopic dermatitis.

Atopic dermatitis and the stratum corneum: part 2: other structural and functional characteristics of the stratum corneum barrier in atopic skin.

This three-part review presents what is currently known about the involvement and interdependency of the epidermal barrier and immune response in the etiopathogenesis of atopic dermatitis. Part 1 of this review depicted the role of filaggrin in atopic dermatitis while this article, Part 2, evaluates the role of serine proteases and specific lipids in the structural and functional integrity of the stratum corneum and its multiple barrier functions in atopic dermatitis. Upregulation of serine protease activity causes adverse structural changes of the stratum corneum due to degradation of certain stratum corneum proteins that are integral to epidermal structure and functions, interference with the formation of the stratum corneum intercellular lipid membrane, which normally regulates epidermal water flux and gradient, and induction of a TH2 pattern of inflammation, which is the hallmark profile of atopic skin.

Understanding the pediatric dermatology workforce shortage: mentoring matters.

Objectives: To target pediatric dermatologists directly in order to evaluate their current demographics and the most important motivating factors that influenced their career choice. Pediatric dermatology is one of the pediatric subspecialties with an inadequate supply to meet current patient needs.

Study Design: A survey was designed to evaluate the training pathway, employment status, participation in teaching, and clinical practice characteristics of pediatric dermatologists.
