Background Autosomal recessive congenital ichthyoses (ARCI) are a genetically heterogeneous group of rare and chronic disorders characterized by generalized skin scaling and hyperkeratosis, erythroderma, and palmoplantar keratoderma. Additional features include ectropion, eclabium, ear deformities, foul-smell, joints contractures and walking problems, recurrent infections, as well as pruritus and pain. No curative therapy is available and disease care mainly relies on daily application of topical emollients and keratolytics to the whole-body surface. Altogether, disease signs and symptoms and treatment modalities have a major impact on quality of life of patients and their caregivers. However, very few studies have evaluated the family disease burden in ARCI. Methods We have performed an Italian multicenter cross-sectional study to assess the secondary disease impact on family members of pediatric and adult patients with ARCI, using a validated dermatology-specific questionnaire, the family dermatology life quality index (FDLQI). Disease severity was assessed by the dermatologist in each center. Results Seventy-eight out of 82 patients who were accompanied by at least one family member filled the FDLQI. Forty-eight (61.5%) patients were aged less than 18 years. The mean FDLQI score was 10.3 (median 10), and the most affected dimensions were (1) time needed for care, (2) extra-housework, and (3) household expenditure. Higher total FDLQI score significantly correlated with more severe disease score (P = 0.003). Features associated with greater family burden included recurrent infections (P = 0.004), foul-smell (P = 0.009), palmoplantar keratoderma (P = 0.041), but also presence of scales on the face (P = 0.039) and ear deformities (P = 0.016). Conclusions Our findings highlight the major socio-economic and psychological burden imposed by ARCI on the QoL of family caregivers. In addition, they show that global evaluation of disease impact also on family members is an essential part of patient-reported outcomes. Finally, our data underline the need to develop specific measures for family support.

Given the inadequate overall awareness of the main disease features and treatment modalities of pruritus in pediatric patients with atopic dermatitis, a multidisciplinary Italian expert group met with the major aim of increasing knowledge of the condition for improved diagnosis and better management among specialists involved in disease management. Herein, the overall features of the condition are reviewed, along with its etiopathogenesis and symptoms. Likewise, management options are summarized, emphasizing the need for a multidisciplinary approach, minimally composed of a management team that includes a pediatrician, dermatologist, psychologist, play assistant, and dedicated nurse. In addition to more traditional therapies such as emollients as highlighted by European guidelines, therapeutic patient education in a group or individually is highly encouraged as it helps patients and their parents to better understand the disease and provide practical guidance for dressing and bandaging. It can also aid in outlining coping strategies for itching and sleep disturbance. The utility of distraction techniques should also be stressed as such educational interventions involving the child and their parents can substantially improve the overall quality of life. All approaches should be tailored according to patient age and clinical features and requires individualized strategy to ensure good adherence by both children and their parents. Thus, a holistic approach embracing systemic, topical and psychological interventions is advocated in order to provide patients and their caregivers the best possible care.

Autosomal recessive congenital ichthyoses (ARCI) are characterized by generalized skin scaling, hyperkeratosis, erythroderma, and disabling features affecting the skin (palmoplantar keratoderma, fissures, pain, itch), eyes, ears, and joints. Disease severity and chronicity, patient disfigurement, and time and costs required for care impose a major burden on quality of life. This multicentre cross-sectional study investigated the impact of ARCI on quality of life of patients and families, using the Dermatology Life Quality Index (DLQI), the Children DLQI (CDLQI) and Family Burden of Ichthyosis (FBI) questionnaires. Disease severity was assessed by a dermatologist. A total of 94 patients were recruited, of whom 52 (55.3%) children. Mean age was 20.1 (median 13.5) years. The mean CDLQI/DLQI score was 7.8, and 21 patients scored >10, indicating a major impairment in quality of life: symptoms, feelings and treatment problems were the most affected domains of quality of life. FBI showed a major repercussion on psychological factors and work. The results of this study highlight the impact of ARCI on specific aspects of patient and family life, underlining the need for psychological support.

Cutaneous leishmaniasis (CL) is the most frequent form of leishmaniasis. The auricle is an extremely rare site for CL in the Old World. Auricular CL may be mistaken for other entities, such as relapsing polychondritis (RP). Here we report a pediatric case of Old World auricular CL mimicking RP in a child successfully treated with intralesional liposomal amphotericin B.

Anogenital condylomata acuminata are induced by human papillomavirus (HPV) and they rarely manifest in immunocompetent children. Therapeutic options depend on patient's age and general conditions and extension of the lesions. However, management is still a challenge and recurrences are frequent. Cryotherapy, laser, and surgical treatments in children are painful and frequently require general anesthesia. Imiquimod is a topical immune response modifier and constitutes a noninvasive alternative for the treatment of anogenital condylomata acuminata. Here, we report an infant admitted to our hospital with a giant vegetative papillomatous lesion on the perianal region surrounded by small satellites papules. PCR for HPV confirmed the clinical diagnosis of giant condylomata acuminata due to HPV type 6. The child has been successfully treated with topical 5% imiquimod cream without side effects. Although topical imiquimod is not licensed for pediatric age, this report highlights the potential benefits of its use in selected pediatric cases.

BackgroundCongenital self-healing reticulohistiocytosis (CSHRH), also called Hashimoto-Pritzker disease, is a rare and benign variant of Langerhans cell histiocytosis, characterized by cutaneous lesions without extracutaneous involvement.Case presentationWe present a case of CSHRH with diffuse skin lesions and erosions in the oral mucosa, present since birth and lasting for 2 months, and we perform a review of the literature on Pubmed in the last 10 years.ConclusionsOur case confirm that lesions on oral mucosa, actually underestimated, may be present in patients with CSHRH. Patients affected by CSHRH require a close follow-up until the first years of life, due to the unpredictable course of Langerhans cell histiocytosis, in order to avoid missing diagnosis of more aggressive types of this disorder.

Background/objectives A few studies have documented the effect of local anesthesia for minor dermatologic surgical procedures on children and their parents. Our objective was to evaluate the psychological effect and global satisfaction of a patient-centered approach to dermatologic surgery under local anesthesia. Methods Two self-administered questionnaires were used to evaluate the distress and global satisfaction of 388 children who underwent dermatologic surgery under local anesthesia, accompanied by oral and written therapeutic education measures (structured information and a cartoon brochure illustrating the procedure) addressed to children and parents. Distraction techniques were also used during the procedures. Results Although 54.5% of patients manifested some degree of fear, all other parameters analyzed (pain, surgery-related distress, surgical team-patient and -family relationship, global satisfaction) indicated that the procedures resulted in limited distress and that the large majority of children and parents tolerated them well. Conclusion Specific measures for therapeutic pediatric patient education may be helpful in limiting discomfort, anxiety, and pain perception linked to procedures performed under local anesthesia. Further controlled studies are required to more precisely assess the benefits of specific therapeutic education measures.

Hoarse cry and respiratory stridor are the signs of potentially life-threatening laryngeal involvement in selected severe and frequently early lethal subtypes of inherited epidermolysis bullosa (EB). We present a newborn with generalized skin blistering and onychodystrophy who developed a hoarse cry and inspiratory stridor. Ultrastructural skin examination revealed tonofilament clumping in basal keratinocytes and genetic testing identified the de novo missense mutation p.Arg125Cys in the KRT14 gene, consistent with EB simplex generalized severe, which is characterized by major morbidity in infancy but a favorable long-term prognosis. The present case underlines the importance to consider EB simplex generalized severe in the differential diagnosis of EB infants presenting hoarseness and stridor.

Atopic dermatitis (AD) has been hypothesised to be associated with gut microbiota (GM) composition. We performed a comparative study of the GM profile of 19 AD children and 18 healthy individuals aimed at identifying bacterial biomarkers associated with the disease. The effect of probiotic intake (Bifidobacterium breve plus Lactobacillus salivarius) on the modulation of GM and the probiotic persistence in the GM were also evaluated. Faecal samples were analysed by real-time PCR and 16S rRNA targeted metagenomics. Although the probiotics, chosen for this study, did not shape the entire GM profile, we observed the ability of these species to pass through the gastrointestinal tract and to persist (only B. breve) in the GM. Moreover, the GM of patients compared to CTRLs showed a dysbiotic status characterised by an increase of Faecalibacterium, Oscillospira, Bacteroides, Parabacteroides and Sutterella and a reduction of short-chain fatty acid (SCFA)-producing bacteria (i.e., Bifidobacterium, Blautia, Coprococcus, Eubacterium and Propionibacterium). Taken togheter these results show an alteration in AD microbiota composition with the depletion or absence of some species, opening the way to future probiotic intervention studies.

Fibrolipomatous hamartomas are asymptomatic, subcutaneous lumps usually located on the infant's heels. There is wide heterogeneity in the naming of and management of this condition. Ultrasound examination permits a clear distinction from other disorders. We report herein a case of palmoplantar fibrolipomatous hamartomas.

In this study, we analyzed multiple somatic mutations in 10 genes relevant in melanoma tumorigenesis and targeted therapies. Overall, 45% of the tumors showed mutations and, in particular, 33% had multiple mutations. Based on our results, we conclude that the assessment of mutation status of multiple genes, including CDKN2A, could provide a genetic profile that can be useful as a prognostic and therapeutic marker in melanocytic tumors.

Background The term ichthyosis describes a generalized disorder of cornification characterized by scaling and/or hyperkeratosis of different skin regions. Mutations in a broad group of genes related to keratinocyte differentiation and epidermal barrier function have been demonstrated to play a causative role in disease development. Ichthyosis may be classified in syndromic or non-syndromic forms based on the occurrence or absence of extracutaneous signs. In this setting, the diagnosis of ichthyosis is an integrated multistep process requiring a multidisciplinary approach in order to formulate the appropriate diagnostic hypothesis and to address the genetic testing. Methods Due to the complex features of the different ichthyoses and the high number of genes involved we have investigated a group of 64 patients, affected by syndromic and non-syndromic diseases, using Next Generation Sequencing as a new tool for the molecular diagnosis. Results Using this innovative molecular approach we were able to find pathogenic mutations in 53 out of 64 patients resulting in 82.8 % total detection rate. An interesting result from the analysis of the data is the high rate of novel sequence variations found compared to known mutations and the relevant rate of homozygous mutations. Conclusions The possibility to analyze a large number of genes associated with various diseases allows to study cases with phenotypes not well-determined, giving the opportunity to make new genotype-phenotype correlation. In some cases there were discrepancies between clinical features and histology or electron microscopy and only molecular analysis allowed to definitively resolve the diagnostic dilemma. The genetic diagnosis of ichthyosis leads to a more accurate and effective genetic counseling, allowing correct evaluation of the risk of recurrence, particularly in families with consanguineous background.

Erythrodermic psoriasis is a severe and disabling variant of psoriasis. The authors present the case of a 48-year-old man with psoriasis and hemophilia presented with a history of hepatitis C virus (HCV) infection treated with pegylated interferon alpha-2a and ribavirin therapy. At the end of antiviral therapy, skin manifestation progressively worsened, becoming erythrodermic, with lack of efficacy of steroid therapy. The authors decided to start biological therapy with induction dose of adalimumab (Humira, Abbott Laboratories, Abbott Park, Chicago, IL) 80 mg at Week 0 and 40 mg weekly. In our case, this resulted in a highly effective and safe treatment.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown aetiology. Clinical manifestations of PG are characterized by destructive, necrotizing, and noninfective ulceration of the skin. 20–30% of cases are initiated and aggravated by minor trauma or surgery, a phenomenon named pathergy. PG is related to several autoimmune diseases including ulcerative colitis, Crohn's disease, rheumatoid arthritis, and monoclonal gammopathy. The association with Takayasu's arteritis (TA), a chronic inflammatory and stenotic disease of large and medium-sized arteries, is instead less common. We report a case of PG associated with TA that was induced by an accident with folgoration of the skin; in this case the folgoration can be considered as an exemple of Pathergy, that is, a characteristic feature of PG.

Psoriasis is a chronic inflammatory disease associated with several comorbidities. Osteoporosis is defined as a reduction in bone mineral density with impaired bone microarchitecture. Several mechanisms may be implicated as a possible cause for the association between psoriasis and osteoporosis, such as systemic inflammation, anti-psoriatic drug intake and joint dysfunction for psoriatic arthritis (PsA). The aim of the present study was to assess bone mineral density (BMD) in patients with psoriasis, correlating the prevalence of osteopenia/osteoporosis with Psoriasis Area and Severity Index (PASI) score, mean duration of psoriatic disease, PsA and previous treatments for psoriasis. Forty-three consecutive patients with psoriasis, 19 of whom were affected by the arthropathic form, were enrolled. We evaluated the severity of psoriasis as measured by PASI score, the CASPAR criteria and ultrasounds of the joints to verify the diagnosis of PsA and the age of psoriasis onset to estimate mean disease duration. Patients underwent a bone density scan of the lumbar spine and femoral neck by dual-energy X-ray absorptiometry to measure BMD. Patients with osteopenia/osteoporosis showed a statistically significant longer average duration of psoriatic disease (17 years), compared to patients affected by psoriasis with normal T-score (8.8 years) (P = 0.04). The linear logistic regression confirms a significant relation between mean psoriatic disease duration and BMD alterations (P = 0.04). Our results suggest the necessity of an early diagnostic evaluation of bone metabolism in patients with psoriasis, especially if characterized by longer disease duration.

Bullous dermolysis of the newborn (BDN) is a subtype of dystrophic epidermolysis bullosa characterized by rapid improvement in skin fragility within the first months of life, associated with typical immunofluorescence and ultrastructural features. Inheritance can be autosomal dominant or recessive. We report here 4 cases of BDN, 2 of which presented with aplasia cutis congenita of the lower extremities. All patients improved rapidly and blister formation ceased by the third month of life in 3 cases. In these patients only residual milia, nail dystrophies and atrophic scarring at sites of aplasia cutis were visible by one year. Family history indicated dominant inheritance in 2 cases, confirmed by identification of COL7A1 mutation. Molecular analysis also revealed recessive inheritance in the 2 sporadic cases. A literature search identified several patients with BDN born with skin defects localized to the lower extremities. In conclusion, these findings indicate that aplasia cutis congenita is not an infrequent manifestation of BDN.

Psoriasis is caused by a combination of genetic, immunologic, and environmental factors. The vitamin D receptor (VDR) is involved in antiproliferative and prodifferentiation pathways in keratinocytes and exerts immunosuppressive effects. We aimed to investigate possible associations between VDR polymorphisms and psoriasis susceptibility and to evaluate functional effects of potential psoriasis-associated polymorphisms. We genotyped 108 patients with psoriasis and 268 healthy controls at 5 VDR polymorphisms (A-1012G, FokI, BsmI, ApaI, and TaqI) by TaqMan allelic-discrimination real-time polymerase chain reaction. We found a significant increased overall risk of psoriasis for the VDR A-1012G promoter polymorphism (odds ratio [OR]=2.43, 95% confidence interval [CI]: 1.15-5.13; p=0.05). A significant higher frequency (p=0.035) of the A allele was found in psoriatic cases compared with controls. In a case-case analysis, a statistically significant association between A-1012G and family history emerged (p=0.033). Furthermore, a significant association of A-1012G risk genotypes with a lower expression of VDR mRNA emerged (p=0.0028). Our data show that VDR promoter A-1012G polymorphism is associated with psoriasis risk and suggest that this polymorphism may modulate psoriasis risk by affecting VDR expression.

Vitiligo is an acquired depigmentary skin disorder due to the loss of cutaneous melanocytes or alteration in melanocyte function, affecting over 0.5% of the world population. The exact cause of melanocyte loss in non-segmental vitiligo is still debatable, but many observations have pointed to the main role of cellular immunity. Earlier evidence has shown that depigmenting vitiligo skin is accompanied by CD8+ T cytotoxic lymphocytes infiltrates at the dermal-epidermal junction. Dysregulation of Tregs may be one of the factors that can break tolerance to melanocyte self-antigens and contribute to the pathogenesis of vitiligo. The objectives of the present study were to provide evidence of the presence of a functional defect and decrease of peripheral regulatory T cells in patients affected by vitiligo, supporting the hypothesis of their involvement in the pathogenesis of the disease, opening new possibilities to advance therapeutic approaches.

Psoriasis is a common chronic relapsing inflammatory cutaneous disease; the main role in the inflammation of this condition is played by lymphocyte Th1, Th17 and their cytokines. The activity of these cells is modulated by a particular kind of T cells recently described: the T regulatory cells (Treg). These are able to inhibit the immunological response and to maintain the cutaneous immunological homeostasis, thus preventing autoimmunity against self antigens. Few data are available in the literature as to Treg in psoriasis; several studies demonstrate that the function of these cells is impaired in this condition and treatments for psoriasis may increase the number and activity of Treg. The role of these cells in the pathogenesis of psoriasis is very important to understand how they may contribute to the development of this cutaneous disorder. In the near future it would be possible to target therapies at these defects, improving the activity of these cells and maintaining cutaneous homeostasis, preventing psoriasis or other inflammatory cutaneous conditions.

Effective management of wound healing is a considerable challenge for clinicians. Patients underlying condition, accurate assessment of the wound and exudates, as well as selection of an appropriate dressing is all important factors for success. A variety of dressings are available to the clinician for the management of exudates. Hydrofiber dressings are a relatively new concept, and can be very cost effective because they can be worn for several days at a time. This report will review clinical evidences on the use of Hydrofiber dressing for the management of epithelial lesions, deal with current knowledge on the mechanism of action of this compound towards the epithelial wound healing process, immunological aspects and will also discuss relevant patents.

Regulatory T-cells (T-reg) play a central role in the immunopathogenesis of psoriasis. T-reg cells are both functionally and numerically impaired in psoriasis and they are up-regulated by drug therapy. To analyse the circulating CD4+CD25 bright FOXP3+ subset in 14 patients with vulgaris/arthropathic psoriasis treated with biological drugs and to investigate their relationship with the clinical response. The CD4+ CD25 bright FOXP3+ expression was determined in peripheral blood by flow cytometry at baseline and during treatment. A response was obtained in 10/14 patients with increased CD4+ CD25 bright FOXP3+ (T-reg) in peripheral blood after the first month and then 4 months after therapy with biological drugs. This increase is associated with the achievement of a clinical response and with a reduction in the Psoriasis Activity and Severity Index (PASI) score. 2/14 patients showed a decrease in T-reg after drug therapy and this decrease correlated with a worsening of the clinical skin. Biological drugs induce circulating T-reg up-regulation in psoriatic patients; such an increase is an early predictive marker of clinical response.

Endothelin 1, a powerful endogenous vasoconstrictor and mitogen, may be causal to pulmonary hypertension. Evidence also suggests that endothelin (ET) may have a fundamental role in scleroderma pathogenesis, including pulmonary arterial hypertension (PAH), a leading cause of death in patients with scleroderma. The development of a new class of drug, ET receptor antagonists, provides an improved outlook for patients with scleroderma and related diseases. Increasing vigilance toward early detection of PAH in scleroderma and a multidisciplinary approach to diagnosis and treatment may improve the clinical outcome for these patients. We describe the efficacy and safety of bosentan, an orally active dual ET-receptor antagonist, in patients with digital ulcers. Bosentan increases exercise capacity and improves hemodynamics in patients with pulmonary hypertension, suggesting that ET has an important role in pulmonary hypertension but in our experience also for refractory skin ulcers.

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation and blood vessel walls necrosis. Usually the skin is one of the first organs involved, especially with damage of small to medium size vessels. The cutaneous patterns may help clinicians to diagnose these diseases at the beginning of their course, preventing complications due to internal organ involvement. The following case presents a patient with a microscopic polyangiitis that started with several skin ulcerations localized on the inferior limbs.

Background Families of children affected with atopic dermatitis (AD) often report fear and anxiety regarding treatment with topical corticosteroids (TCS), which may lead to reduced compliance. The objective of our study was to measure, through a standardized questionnaire, fear of TCS in families of pediatric patients with AD and to identify items associated with fear. Methods Families of pediatric patients with AD were enrolled in 9 Italian centers of pediatric dermatology. Enrolled parents were invited to fill in a questionnaire including questions on sociodemographic and clinical characteristics and 3 sets of questions on corticosteroid phobia (general fear, specific fears, behaviours regarding TCS). Determinants of the level of general fear were investigated through multivariable analysis. Results A total of 300 outpatients with AD were enrolled. Most parents (80%) had a high instruction level. Eighty-one percent reported to have a certain amount of fear of TCS. At the multivariable analysis, fear of TCS was associated with the following items: believing that TCS treatment advantages do not overweight disadvantages (P = 0.011); believing that TCS may be dangerous independently from the specific side effect (P
