RESUMO
BACKGROUND: Acne vulgaris varies in clinical severity, from minimal comedonal disease to severe hemorrhagic and ulcerative lesions with scarring. While a family history confers a higher risk for developing acne, the correlation between heritability and clinical severity remains unclear. OBJECTIVE: To examine the natural history and heritability of severe acne with scarring in patients undergoing isotretinoin therapy. METHODS: A total of 101 subjects with severe acne with scarring and its variants, including acne conglobata and acne fulminans, were enrolled. All subjects and adult family members underwent an interview regarding their acne, and a corresponding "historical" Investigator's Global Assessment (hIGA) score (0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe) was assigned. Study assessors performed an "examination" Investigator's Global Assessment (eIGA) based on the clinical examination of each subject (0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe). A detailed family history and pedigree were documented. RESULTS: Most subjects were Caucasian (44.5%) and male (79.2%) who had previously used doxycycline and/or minocycline (86.1%). The mean eIGA and hIGA scores were 2.7 and 4.4, respectively. 37.2% of subjects had one first-degree relative with a history of moderate or severe acne with scarring; of note, of the patients with hemorrhagic disease, 30% had at least one parent with moderate or severe acne. CONCLUSIONS: Severe forms of acne often "cluster" in families, underscoring the heritable nature of acne and the prognostic value of a family history of moderate or severe disease.

BACKGROUND: Atopic dermatitis (AD) is a chronic, inflammatory skin disease that affects as many as 12.5% of children aged 0-17 years and 3% of the adult population. In the United States, 31.6 million children and adults are estimated to be living with AD. OBJECTIVE: Therapeutic patient education (TPE) has proven its value in the management of chronic diseases for which adherence to therapy is suboptimal. This article explores experts' opinions and treatment practices to determine if TPE is a recommended and effective method for treating AD. METHODS: Forty-two (51%) of 82 Councilors and Associates of the International Eczema Council (IEC), an international group with expertise in AD, responded to an electronic survey on TPE and AD. RESULTS: Most respondents (97.5%) agreed that TPE should play an important role in the management of AD. Many respondents (82.9%) believed that all patients with AD, regardless of disease severity, could benefit from TPE. LIMITATIONS: The International Eczema Council survey lacks specific information on AD severity. CONCLUSIONS: Publications have shown the positive effect of TPE on the course of the disease, the prevention of complications, and the autonomy and quality of patient life. Survey respondents agreed that TPE can improve the quality of patient care and patient satisfaction with care.
RESUMO
Recurrent herpes labialis (RHL) is an incredibly common condition, though the medical literature evaluating pediatric aspects is limited. This paper assesses prevalence and therapeutic studies of pediatric RHL as well as disease complications. A comprehensive literature search of English-language citations based on PubMed queries of selected terms was performed, with exclusion if methodology was not discussed, or if studies had 10 or fewer patients. RHL prevalence in pediatrics has been assessed by measures of point and periodic prevalence, though methodologic limitations may under- or over-estimate the true prevalence of RHL. Studies have been conducted to evaluate therapeutic safety, tolerability, and efficacy of antivirals in the pediatric population. Pediatric RHL point prevalence ranges from 0.72% to 5.2% depending on the population study and the methodologies used. Pediatric RHL carries a significant public health burden and is often implicated in patients with eczema herpeticum, erythema multiforme, reactive infectious mucositis eruptions, and hypersensitivity reactions. There are few studies that evaluate the rates of occurrence of these sequelae associated with pediatric RHL.

Koolen-de Vries syndrome (KdVS), also referred to as the 17q21.31 microdeletion syndrome, is a rare genetic disorder characterized by developmental delay, typical facial dysmorphism, and congenital defects. Associated anomalies include many cutaneous findings. Here, we report a 17-year-old boy with KdVS (17q21.31 microdeletion syndrome) who presented with diffuse freckling and multiple pigmented lesions, found to be most consistent with atypical café-au-lait macules (CALMs) on biopsy. We review the cutaneous findings commonly associated with KdVS (17q21.31 microdeletion syndrome) and propose the addition of diffuse freckling and atypical CALMs, histologically similar to those that may be found in neurofibromatosis type 1, to the cutaneous findings associated with KdVS (17q21.31 microdeletion syndrome).

Non-uremic calciphylaxis is a rare, life-threatening condition characterized clinically by cutaneous necrosis and histologically by calcium deposition in small vessel walls. The etiology of non-uremic calciphylaxis remains the subject of ongoing speculation and debate. Herein we present a patient with calciphylaxis who had normal kidney function and numerous rheumatologic diseases, namely systemic lupus erythematosus (SLE), Sjogren syndrome (SS), and myasthenia gravis (MG). We review the pathophysiology, possible mechanisms, and management for non-uremic calciphylaxis.

Most guidelines on neonatal skin care emphasize issues pertaining to healthy, term infants. Few address the complex task of skin barrier maintenance in preterm, very preterm, and extremely preterm infants. Here, we provide an evidence-based review of the literature on skin care of preterm neonates. Interestingly, the stratum corneum does not fully develop until late in the third trimester, and as such, the barrier function of preterm skin is significantly compromised. Numerous interventions are available to augment the weak skin barrier of neonates. Plastic wraps reduce the incidence of hypothermia while semipermeable and transparent adhesive dressings improve skin quality and decrease the incidence of electrolyte abnormalities. Tub bathing causes less body temperature variability than sponge bathing and can be performed as infrequently as once every four days without increasing bacterial colonization of the skin. Topical emollients, particularly sunflower seed oil, appear to reduce the incidence of skin infections in premature neonates-but only in developing countries. In developed countries, studies indicate that topical petrolatum ointment increases the risk of candidemia and coagulase-negative Staphylococcus infection in the preterm population, perhaps by creating a milieu similar to occlusive dressings. For preterm infants with catheters, povidone-iodine and chlorhexidine are comparably effective at preventing catheter colonization. Further studies are necessary to examine the safety and efficacy of various skin care interventions in premature infants with an emphasis placed on subclassifying the patient population. In the interim, it may be beneficial to develop guidelines based on the current body of evidence.

Peanut allergy, the most persistent and deadly of the food allergies, has become more prevalent worldwide in recent decades. Numerous explanations have been offered for the rise in peanut allergy, which has been more pronounced in Western, industrialized nations. In infants who are at increased risk of peanut allergy, new evidence indicates that early introduction of peanuts can help prevent allergy development. This counterintuitive finding directly contradicts the previously established practice of peanut avoidance for high-risk infants but is supported by clinical and basic science evidence. Here, we review the literature contributing to our evolving understanding of nut allergy, emphasizing the translation of this work to clinical practice.

Primary cutaneous aspergillosis is a rare but potentially life-threatening disease. We present the case of a premature infant who developed primary cutaneous aspergillosis with Aspergillus niger at the site of a skin abrasion that had been treated with a purple-colored cyanoacrylate product. The infection was treated successfully with gentle debridement of the cyanoacrylate product, followed by intravenous voriconazole and topical fluconazole. To our knowledge, this is the first reported case of primary cutaneous aspergillosis occurring at the site of cyanoacrylate-based skin adhesive.

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.
