The role of the nurse in the care and management of patients with atopic dermatitis.

BACKGROUND: The purpose of this paper is to provide an overview of key aspects of specialised dermatology nursing practice in the management of patients with moderate to severe atopic dermatitis. The role of dermatology nurse specialists in supporting patients and promoting disease understanding, education and treatment adherence continues to evolve. As features of specialised nursing care can also inform other nursing staff in a wide range of care settings, an overview of key components is examined. Observations presented are from a pan-European perspective and represent the collected view of a group of dermatology nurse specialists, dermatologists and patient advocates following two round-table discussions. MAIN BODY: Atopic dermatitis is a common, chronic, inflammatory disease characterised by erythematous/scaling skin lesions, with often intense pruritus. Disease course is cyclic with periodic disease flares of varying intensity, presenting management challenges to patients and families. Dermatology nurse specialists play a key role in providing education and substantial patient support to improve treatment outcomes and quality of life to patients and their family, delivered within a multidisciplinary team framework. Nurse-led education and 'eczema schools' are of benefit in reducing disease severity and improving quality of life by enhancing self-management, adherence and patient engagement. eHealth tools, such as patient portals or online training platforms, can provide online learning, individualised education, and help to improve engagement. These and other initiatives, such as written action plans, are all essential to improve or maintain treatment adherence, self-management and quality of life. CONCLUSIONS: Dermatology nurse specialists play a central role in the assessment and management of moderate to severe atopic dermatitis patients and families. This places them in an ideal position to build strong and often long-term relationships with patients and parents. Such engagement promotes trust, assists in setting realistic expectations of treatment and outcomes, and enhances self-management and engagement in their own care. Providing emotional support, as well as formal and systematic education (including individualised practical advice) all contribute to improved treatment adherence and can enhance the quality of life of patients and their families throughout the course of this long-term condition.

Recommendations for pimecrolimus 1% cream in the treatment of mild-to-moderate atopic dermatitis: from medical needs to a new treatment algorithm.

Pimecrolimus 1% cream is an effective, non-corticosteroid, topical anti-inflammatory treatment for atopic dermatitis (AD). The aim of this article was to review published clinical data that have examined how pimecrolimus can address the medical needs of AD patients. Clinical studies have demonstrated that early treatment with pimecrolimus decreases the progression to disease flares, rapidly improves pruritus and significantly enhances quality of life. Patients find the formulation easy to apply, which may result in improved adherence with the treatment regimen. Pimecrolimus, in contrast to topical corticosteroids (TCSs), does not induce skin atrophy or epidermal barrier dysfunction and is highly effective for the treatment of AD in sensitive skin areas. Furthermore, pimecrolimus reduces the incidence of skin infections compared with TCSs and is not associated with other TCS-related side effects such as striae, telangiectasia and hypothalamic-pituitary-adrenal axis suppression. An additional benefit of pimecrolimus is its substantial steroid sparing effect. On the basis of these data, a new treatment algorithm for patients with mild-to-moderate AD is proposed in which pimecrolimus is recommended as a first line therapy for patients with established mild AD at the first signs and symptoms of disease. Pimecrolimus is also recommended for mild-to-moderate AD after initial treatment with a TCS. After resolution of lesions, maintenance treatment with pimecrolimus may effectively prevent subsequent disease flares. In conclusion, the clinical profile of pimecrolimus suggests that it may be considered the drug of choice for the treatment of mild-to-moderate AD in children as well as adults and particularly in sensitive skin areas.

Therapeutic patient education in children with atopic dermatitis: position paper on objectives and recommendations.

Poor adherence is frequent in patients with atopic dermatitis (AD), leading to therapeutic failure. Therapeutic patient education (TPE) helps patients with chronic disease to acquire or maintain the skills they need to manage their chronic disease. After a review of the literature, a group of multispecialty physicians, nurses, psychologists, and patients worked together during two international workshops to develop common recommendations for TPE in AD. These recommendations were structured as answers to nine frequently asked questions about TPE in AD: What is TPE and what are its underlying principles? Why use TPE in the management of AD? Who should benefit from TPE in AD? How can TPE be organized for AD? What is the assessment process for TPE in AD? What is the evidence of the benefit of TPE in AD? Who are the people involved in TPE? How should TPE be funded in dermatology? What are the limits of the TPE process?

Therapeutic patient education in atopic dermatitis: worldwide experiences.

Therapeutic patient education (TPE) has proven effective in increasing treatment adherence and improving quality of life (QoL) for patients with numerous chronic diseases, especially atopic dermatitis (AD). This study was undertaken to identify worldwide TPE experiences in AD treatment. Experts from 23 hospitals, located in 11 countries, responded to a questionnaire on 10 major items. Patients in TPE programs were mainly children and adolescents with moderate to severe AD or markedly affected QoL. Individual and collective approaches were used. Depending on the center, the number of sessions varied from one to six (corresponding to 2 to 12 hours of education), and 20 to 200 patients were followed each year. Each center's education team comprised multidisciplinary professionals (e.g., doctors, nurses, psychologists). Evaluations were based on clinical assessment, QoL, a satisfaction index, or some combination of the three. When funding was obtained, it came from regional health authorities (France), insurance companies (Germany), donations (United States), or pharmaceutical firms (Japan, Italy). The role of patient associations was always highlighted, but their involvement in the TPE process varied from one country to another. Despite the nonexhaustive approach, our findings demonstrate the increasing interest in TPE for managing individuals with AD. In spite of the cultural and financial differences between countries, there is a consensus among experts to integrate education into the treatment of eczema.

Panniculitis as the presenting sign of a myelodysplastic syndrome in an adolescent boy.

Panniculitis is an uncommon condition in childhood and may prove difficult to diagnose both clinically and histologically. The clinical spectrum is similar to that in adults and has been associated with many primary diseases. Noninfectious causes are less common in children than in adults. The pathogenesis remains uncertain in a significant number of children. In some it may be a malignant, unremitting disease which can be fatal. We present a boy aged 13 years with panniculitis of the right foot as presenting sign for the ultimate diagnosis myelodysplasia-acute myeloid leukemia. To our knowledge this is the first report on a young boy.

Genotypic and gene expression studies in congenital melanocytic nevi: insight into initial steps of melanotumorigenesis.

Large congenital melanocytic nevi (CMNs) are said to have a higher propensity to malignant transformation compared with acquired nevi. Thus, they represent a good model for studying initial steps of melanotumorigenesis. We have performed genotypic (karyotype, fluorescence in situ hybridization, and mutational analyses) and differential expression studies on a large cohort of medium (n=3) and large (n=24) CMN. Chromosomal abnormalities were rare and single, a feature probably reflecting the benignity of these lesions. Mutational screening showed a high frequency of NRAS mutations in our series (19/27 cases, 70%), whereas BRAF mutations were less common (4/27 cases, 15%). Differential did not show significant alterations of cellular processes such as cell proliferation, cell migration/invasion, angiogenesis, apoptosis, and immune/inflammatory responses. However, significant downregulation of genes involved in pigmentation and upregulation of genes playing a role in DNA protection were observed. Lastly, our microarrays displayed upregulation of genes mediating chemoresistance in cancer. As alteration of pigmentation mechanisms can trigger oxidative damage, increased expression of genes involved in maintenance of DNA integrity might reflect the ability of nevocytic cells to self-protect against cellular stress. Furthermore, the observed alterations linked to chemoresistance might partially account for the well-known inefficacy of chemotherapy in malignant melanoma.

Chromosomal translocations as a mechanism of BRAF activation in two cases of large congenital melanocytic nevi.

Genetic studies of melanocytic tumors have mainly demonstrated activation of oncogenes such as NRAS or BRAF through point mutations. In two cases of large congenital melanocytic nevi, we observed a chromosomal translocation involving the BRAF oncogene on chromosome 7q34, resulting in both cases in removal of the auto-inhibitory N-terminal regulatory domain (hence the Ras-guanosine triphosphate binding domain) of BRAF from its protein kinase domain. This is early evidence of BRAF activation through chromosomal translocation in melanocytic tumors. Because BRAF point mutations are rather rare in congenital melanocytic nevi and melanoma arising in non-sun-exposed area, the molecular mechanism of oncogenic activation as described here could be a recurrent molecular feature in these groups of melanocytic tumors.

Identification of a lethal form of epidermolysis bullosa simplex associated with a homozygous genetic mutation in plectin.

Genetic mutations in plectin, a cytoskeleton linker protein expressed in a large variety of tissues including skin, muscle, and nerves, cause epidermolysis bullosa simplex with muscular dystrophy, a recessive inherited disease characterized by blistering of the skin and late onset of muscular dystrophy, and Ogna epidermolysis bullosa simplex, a rare dominant inherited form of epidermolysis bullosa simplex with no muscular involvement. Here we report a novel homozygous genetic mutation (2727del14) in the plectin gene (PLEC1) associated with a lethal form of recessive inherited epidermolysis bullosa in a consanguineous family with three affected offspring. This new clinical variant of epidermolysis bullosa is characterized by general skin blistering, aplasia cutis of the limbs, developmental complications, and rapid demise after birth. Mutation 2727del14 is the first genetic defect described in PLEC1 that disrupts the plakin domain of plectin. The severe phenotype of the patients may be linked to the role of the N-terminal domain in the function of plectin and develops the understanding of the genotype-phenotype correlations in the genodermatoses affecting the dermal-epidermal junction.

Multiple cutaneous granular cell tumors in a child in remission for Hodgkin's disease.

Multiple cutaneous granular cell tumors are uncommon among children. We describe a 13-year-old boy with Hodgkin's disease in remission for 3 years who had multiple cutaneous granular cell tumors. We wondered whether this association was real or a coincidence and whether this child was at increased risk of development of malignant granular cell tumors.

Curettage of giant congenital melanocytic nevi in neonates: a decade later.

BACKGROUND: Currently, there is tremendous uncertainty regarding how giant congenital melanocytic nevi (GCMN) should be treated. Our approach to patients with GCMN is based on 2 main considerations: (1) obtain an acceptable cosmetic result to decrease the psychosocial inconvenience to the patient, and (2) attempt to minimize the risk of malignancy. For the past 10 years we have treated GCMN by curettage in the neonatal period. We report our experience and results. OBSERVATIONS: Sixteen neonates with GCMN were treated by curettage between 1990 and 2000. Biopsy specimens were obtained and the patients received close clinical follow-up. In most patients cosmetic and functional results were good, and, to date, no melanoma has been observed in this series. CONCLUSIONS: Curettage offers an adequate alternative to surgical excision when performed during the first 2 weeks of life. Patients and parents are pleased with the cosmetic and functional results and thereby suffer less from the psychosocial inconvenience caused by these lesions. Careful long-term follow-up of these children is essential to monitor final cosmetic outcome and reduce the potential for malignancy.
