High Dickkopf-1 levels are associated with chronic inflammation in children with sickle cell disease.

Objectives: Sickle bone disease (SBD) is a chronic complication of sickle cell disease (SCD) whose pathogenesis is not completely understood. Chronic inflammation associated with SCD could alter bone remodeling. Our aim was to analyze the serum levels of bone remodeling markers in a group of SCD children to evaluate their involvement in the SBD.

The risk of venipuncture in newborn with severe hemophilia: Case report of a large elbow hemorrhage and literature review of compartment syndrome.

Hemophilias are hemorrhagic congenital rare diseases. The gold standard of therapy in hemophilics is the intravenously replacement therapy. We can infuse intravenously plasma derived factors (FVIII for Hemophilia A and FIX for Hemophilia B) or recombinant products ( clotting factor synthetically produced).

Antithyroid treatment improves thrombocytopenia in a young patient with graves' disease.

Autoimmune thyroid disorders, including Graves' disease and Hashimoto's thyroiditis, have been reported in patients with primary immune thrombocytopenia (ITP). Several etiopathogenetic mechanisms connecting thyroid diseases and thrombocytopenia have been described. Thrombocytopenia is often documented in patients with Graves' disease, due to reduced platelet life span in hyperthyroidism, immune dysregulation and genetic predisposition (HLA B8 presence).

Fatigue perception in a cohort of children with chronic immune thrombocytopenia and their caregivers using the PedsQL MFS: Real-life multicenter experience of the Italian Association of Pediatric Hematology and Oncology (AIEOP).

Background: Fatigue is an important clinical and psychological aspect for a significant number of children affected by immune thrombocytopenia (ITP). To date, few studies have explored fatigue and its relationship with chronic ITP in pediatric age. The aim of the present multicentric pilot study is to determine fatigue perception in a large group of children with chronic ITP and their caregivers using the PedsQL Multidimensional Fatigue Scale (PedsQL MFS), and to compare the results with those of healthy control subjects.

Focus on MicroRNAs as Biomarker in Pediatric Diseases.

Background: MiRNAs are a class of small non-coding RNAs that are involved in the post-transcriptional regulation of gene expression. MiRNAs are considered a class of epigenetic biomarkers. These biomarkers can investigate disease at different stages: diagnosis, therapy or clinical follow-up.

Children in Coronaviruses' Wonderland: What Clinicians Need to Know.

Human coronaviruses (HCoVs) commonly cause mild upper-respiratory tract illnesses but can lead to more severe and diffusive diseases. A variety of signs and symptoms may be present, and infections can range in severity from the common cold and sore throat to more serious laryngeal or tracheal infections, bronchitis, and pneumonia. Among the seven coronaviruses that affect humans (SARS)-CoV, the Middle East respiratory syndrome (MERS)-CoV, and the most recent coronavirus disease 2019 (COVID-19) represent potential life-threatening diseases worldwide.

Venous Thromboembolism in Children: From Diagnosis to Management.

Venous thromboembolism (VTE) in children is a rare occurrence, although in recent decades we have seen an increase due to several factors, such as the rise in survival of subjects with chronic conditions, the use of catheters, and the increased sensitivity of diagnostic tools. Besides inherited thrombophilia, acquired conditions such as cardiovascular diseases, infections, chronic disorders, obesity and malignancy are also common risk factors for paediatric VTE. The treatment of paediatric VTE consists of the use of heparins and/or vitamin K antagonists to prevent dissemination, embolization, and secondary VTE.

Thrombopoietin Receptor Agonists in Children with Immune Thrombocytopenia: A New Therapeutic Era.

Background And Objective: Immune thrombocytopenia (ITP) is a common bleeding disorder in childhood. The management of ITP in children is controversial, requiring personalized assessment of patients and therapeutic choices. Thrombopoietin receptor agonists (TPO-RAs), eltrombopag and romiplostim, have been shown to be safe and effective for the treatment of pediatric ITP.

Uniparental disomy and pretreatment IGF-1 may predict elevated IGF-1 levels in Prader-Willi patients on GH treatment.

Pediatric patients with Prader-Willi syndrome (PWS) can be treated with recombinant human GH (rhGH). These patients are highly sensitive to rhGH and the standard doses suggested by the international guidelines often result in IGF-1 above the normal range. We aimed to evaluate 1 the proper rhGH dose to optimize auxological outcomes and to avoid potential overtreatment, and 2 which patients are more sensitive to rhGH.

Alagille Syndrome: A Novel Mutation in Gene.

Alagille syndrome is an autosomal dominant multisystem disorder with variable phenotypic penetrance, caused by heterozygous mutations in or , encoding for the components of the Notch signaling pathway. In this paper, we described a novel mutation not yet reported in literature. This 3-years old male child was referred to our Clinical Genetics Unit because of delayed psychomotor development, systolic murmur, dysmorphic facial features, and hypertransaminasemia.
