Cost-utility analysis of propranolol versus corticosteroids in the treatment of proliferating infantile hemangioma in Italy

Objectives Infantile hemangioma (IH) is the most common childhood benign tumour. A recent phase II/III study has demonstrated the success of propranolol for involution of infantile hemangioma as well as a better efficacy and safety when indirectly compared with corticosteroids. The purpose of this study was to estimate the cost-utility of propranolol (Hemangiol), a new medicinal product and the first to be authorized for this specific paediatric indication, versus corticosteroids in the treatment of proliferating infantile hemangioma requiring systemic therapy

Chapter Patient-generated evidence in Epidermolysis Bullosa (EB): Development of a questionnaire to assess the Quality of Life

Epidermolysis Bullosa (EB) is a group of genetic conditions that cause fragile and blistering skin. Although there are different types of EB, which differ in severity, their signs and symptoms overlap. As a result of this disorder, patients face an unbearable burden in their lives, and their Quality of Life (QoL) is negatively affected at every life cycle stage. Nevertheless, the assessment of the quality of life of these patients is scanty. This project aims to develop a patient-centered questionnaire to assess the QoL of EB patients. This tool will be a valid aid for clinicians to understand patients better and identify the areas that need more attention; moreover, it will allow them to follow the patients over time and evaluate the impact of any treatments. The methodological process to develop the questionnaire consisted of two phases: firstly, a critical review of scientific literature was performed; secondly, a pseudo-Delphi study was carried out. A multidisciplinary panel (including patients, caregivers, and clinicians) actively participated in round tables to discuss the main areas of interest. Starting from this initial set of areas and through the repetition of Delphi (up to three rounds), a gradual refinement of the statements was carried out to define a list of items to be included in an easy-to-use but meaningful questionnaire. The final patient-centered questionnaire is thus able to measure the QoL beyond the physical symptoms and the clinical evolution of the disease, encompassing functional autonomy, psycho-emotional state, social relations and the working field

Frequent Occurrence of Aplasia Cutis Congenita in Bullous Dermolysis of the Newborn.

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

Early immunopathological diagnosis of ichthyosis with confetti in two sporadic cases with new mutations in keratin 10.

Ichthyosis with confetti (IC) is a severe non-syndromic ichthyosis due to heterozygous mutations in the KRT10 gene. The disease manifests at birth with erythroderma and scaling and is characterised by the gradual development of numerous confetti-like spots of normal skin. Diagnosis of IC is frequently delayed until adolescence or even adulthood. We report 2 young children who were first diagnosed as having congenital ichthyosiform erythroderma. However, the development of thick, confluent hyperkeratotic plaques together with the histopathological finding of keratinocyte vacuolisation in the suprabasal epidermis evoked IC. Immunofluorescence analysis showed a highly reduced keratin 10 expression within the cytoplasm of suprabasal keratinocytes and its characteristic mislocalisation to the nuclei. The diagnosis was confirmed by the identification of 2 previously unreported mutations in intron 6 and exon 7 of KRT10. Careful clinical examination then showed the presence of the first spots of normal skin in both patients at the age of 2.5 and 5 years, respectively. These cases point to the usefulness of immunofluorescence analysis of keratin 10 expression for an early diagnosis of IC

Proteasome-mediated degradation of keratins 7, 8, 17 and 18 by mutant KLHL24 in a foetal keratinocyte model: Novel insight in congenital skin defects and fragility of epidermolysis bullosa simplex with cardiomyopathy

Epidermolysis bullosa simplex (EBS) with cardiomyopathy (EBS-KLHL24) is an EBS subtype caused by dominantly inherited, gain-of-function mutations in the gene encoding for the ubiquitin-ligase KLHL24, which addresses specific proteins to proteasomal degradation. EBS-KLHL24 patients are born with extensive denuded skin areas and skin fragility. Whilst skin fragility rapidly ameliorates, atrophy and scarring develop over time, accompanied by life-threatening cardiomyopathy. To date, pathogenetic mechanisms underlying such a unique disease phenotype are not fully characterized. The basal keratin 14 (K14) has been indicated as a KLHL24 substrate in keratinocytes. However, EBS-KLHL24 pathobiology cannot be determined by the mutation-enhanced disruption of K14 alone, as K14 is similarly expressed in foetal and postnatal epidermis and its protein levels are preserved both in vivo and in vitro disease models. In this study, we focused on foetal keratins as additional KLHL24 substrates. We showed that K7, K8, K17 and K18 protein levels are markedly reduced via proteasome degradation in normal foetal keratinocytes transduced with the mutant KLHL24 protein (Delta N28-KLHL24) as compared to control cells expressing the wild-type form. In addition, heat stress led to keratin network defects and decreased resilience in Delta N28-KLHL24 cells. The KLHL24-mediated degradation of foetal keratins could contribute to congenital skin defects in EBS-KLHL24. Furthermore, we observed that primary keratinocytes from EBS-KLHL24 patients undergo accelerated clonal conversion with reduced colony forming efficiency (CFE) and early replicative senescence. Finally, our findings pointed out a reduced CFE in Delta N28-KLHL24-transduced foetal keratinocytes as compared to controls, suggesting that mutant KLHL24 contributes to patients' keratinocyte clonogenicity impairment

Surgical treatment of septate uterus in cases of primary infertility and before assisted reproductive technologies

Septate uterus is the most common congenital uterine malformation in women with infertility. Several criteria are available for the definition of septate uteri, such as the one proposed by the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynecological Endoscopy (ESGE) (ESHRE/ESGE), or by the American Society for Reproductive Medicine (ASRM), with notable differences between the two. Recently, a simplified classification was proposed by the Congenital Uterine Malformations Experts (CUME), where a septum is defined as an internal indentation depth≥10mm. To date, there is no consensus on the management of women with a septate uterus and infertility. We have performed an extensive literature appraisal and reviewed all the available international guidelines in order to propose a management strategy for infertile patients with a uterine septum. Hysteroscopic septum incision seems to improve natural conception rates in the year following surgery. Moreover, it improves in vitro fertilization (IVF) outcomes when performed before the embryo transfer, by improving embryo implantation rates. On the other hand, for patients with an arcuate uterus (indentation<1.5cm according to the ASRM guidelines) and infertility, it seems that assisted reproductive technologies are the most appropriate first line treatment. However, in cases of recurrent implantation failure or recurrent pregnancy loss following IVF, hysteroscopic section could be proposed. Overall, we recommend hysteroscopic septum incision for patients with primary infertility, and for patients undergoing assisted reproductive technologies

The VASCERN-VASCA working group diagnostic and management pathways for severe and/or rare infantile hemangiomas

The European Reference Network on Rare Multisystemic Vascular Diseases (VASCERN), is dedicated to gathering the best expertise in Europe and provide accessible cross-border healthcare to patients with rare vascular dis-eases. Infantile Hemangiomas (IH) are benign vascular tumors of infancy that rapidly growth in the first weeks of life, followed by stabilization and spontaneous regression. In rare cases the extent, the localization or the number of lesions may cause severe complications that need specific and careful management. Severe IH may be life-threatening due to airway obstruction, liver or cardiac failure or may harbor a risk of functional impairment, severe pain, and/or significant and permanent disfigurement. Rare IHs include syndromic variants associated with extracutaneous abnormalities (PHACE and LUMBAR syndromes), and large segmental hemangiomas. There are publications that focus on evidence-based medicine on propranolol treatment for IH and consensus state -ments on the management of rare infantile hemangiomas mostly focused on PHACES syndrome. The Vascular Anomalies Working Group (VASCA-WG) decided to develop a diagnostic and management pathway for severe and rare IHs with a Nominal Group Technique (NGT), a well-established, structured, multistep, facilitated group meeting technique used to generate consensus statements. The pathway was drawn following two face-to-facePeer reviewe
