Introduction: Experience with the use of allogeneic hemopoietic stem transplantation (AHSCT) in pediatric myelodisplastic syndrome (MDS) in Spain is reviewed.
Methods And Patients: Twenty-four children with MDS were analyzed retrospectively. Median age of the patients was 10 years. Twenty patients received a bone marrow graft and 4 an unrelated cord blood (UCB) transplant; 12 bone marrow grafts were from a matched related donor (MRD) and 8 from a matched unrelated donor (MUD). Conditioning regimen consisted of chemotherapy alone in 17 patients (busulfan and cyclophosphamide +/- melfalan) Seven patients received TBI and cyclophosphamide.
Results: Ten patients died from transplant-related toxicity and 4 had relapse or disease progression post-AHSCT. Nine patients are alive and event-free with a median follow-up of 120 months. EFS rate in the MRD group was 0.48 (SE 0.13) versus 0.25 (SE 0.12) in the MUD/UCB group (p = .07). Lansky score in survivors is >or=90%.
Conclusions: In this historical series of children with MDS, in spite of severe transplant-related toxicity, encouraging EFS outcomes have been achieved after AHSCT with good quality of life.

Comprehensive assessment reveals numerous clinical and neurophysiological differences between MECP2-allelic disorders.

Objective: Rett syndrome (RTT) and MECP2 duplication syndrome (MDS) result from under- and overexpression of MECP2, respectively. Preclinical studies using genetic-based treatment showed robust phenotype recovery for both MDS and RTT. However, there is a risk of converting MDS to RTT, or vice versa, if accurate MeCP2 levels are not achieved.

Purpose: To assess the level of moral distress (MD) and perceptions of ethical climate among pediatric hematology/oncology (PHO) nurses and to identify bioethics topics where increased education was desired.
Methods: In this cross-sectional study, we administered the 26-item Swedish Moral Distress Scale-Revised (sMDS-R), specifically revised and validated for pediatric oncology, in conjunction with the Clinical Ethics Needs Assessment Survey (CENAS). Electronic surveys were sent to inpatient and outpatient PHO nurses.
Familial Platelet Disorder with associated Myeloid Malignancy (FPDMM, FPD/AML, -FPD), caused by monoallelic deleterious germline variants, is characterized by bleeding diathesis and predisposition for hematologic malignancies, particularly myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Clinical data on FPDMM-associated AML (FPDMM-AML) are limited, complicating evidence-based clinical decision-making. Here, we present retrospective genetic and clinical data of the largest cohort of FPDMM patients reported to date.

Background: Inherited cholestatic liver disorders such as progressive familial intrahepatic cholestasis (PFIC) and Alagille syndrome result in significant pruritus and increased serum bile acids, necessitating liver transplantation. This study aims to evaluate the efficacy and safety of Ileal bile acid transport inhibitors (IBATIs) in children with PFIC and Alagille syndrome.
Methods: We conducted a comprehensive search across the databases to identify relevant randomized controlled trials (RCTs), and Covidence was used to screen eligible articles.

On February 6, 2023, a strong earthquake (7.8 Richter scale) shook southwestern Türkiye, and also affected areas in northwest Syria, resulting in over 50 000 fatalities and more than 100 000 injured in Türkiye, in addition to the displacement of approximately 3 million people. In response to an international request for assistance from the Turkish government, the United Kingdom (UK) government deployed an Emergency Medical Team (EMT) Type 1 to provide outpatient care.
