The abnormal TCD rate was 2.9%, with a median age of 6.3 years for first abnormal TCD result. Findings highlight real-world TCD screening practices and results from the largest SCA cohort to date. Data informed the part 3 implementation study for improving stroke screening and findings may inform clinical practice improvements.

Total body irradiation (TBI) is the cornerstone of conditioning regimens in pediatric hematopoietic stem cell transplantation for acute lymphoblastic leukemia. As the late effects and survival comparison between TBI and chemotherapy were well analyzed before, in this study, we aim to focus on the first 100 days and early complications of transplantation.

This retrospective study involves 72 pediatric patients (0 to 18 y) underwent first hematopoietic stem cell transplantation for acute lymphoblastic leukemia between October 2015 and May 2019. Patients are divided into 2 groups regarding conditioning regimens. Conditionings includes either TBI 1200 cGy/6 fractions/3 days and etoposide phosphate or busulfan, fludarabine, and thiotepa. Busulfan was administered IV and according to body weight.

The incidences of acute graft versus host disease grade 2 to 4, veno-occlusive disease, capillary leakage syndrome, thrombotic microangiopathy, blood stream infection, hemorrhagic cystitis and posterior reversible enof ES and CMV reactivation should be considered in TBI-based regimens.Accessing pediatric cancer treatment remains problematic for rural families or those living at increased distances from specialized centers. Rural adult cancer patients or those living far removed from treatment may present with later stage disease, receive different treatments than their closer counterparts, and experience worsened survival. While the financial and psychosocial strain of increased travel is well documented, effects of travel distance on similar outcomes for pediatric cancer patients remain ill-defined. We conducted a systematic review to synthesize literature examining the effect of travel distance and/or rurality (as a proxy for distance) on pediatric cancer treatment experiences and survival outcomes. Included studies examined travel distance to specialized centers or rural status for patients above 21 years of age. Studies were excluded if they focused on financial or quality of life outcomes. We analyzed 24 studies covering myriad malignancies and outcomes, including location of care, clinical trial participation, and likelihood of receiving specialized treatments such as stem cell transplants or proton beam therapy. MPTP mouse Most were retrospective, and 9 were conducted outside the United States. While some studies suggest rural patients may experience worsened survival and those traveling furthest may experience shorter hospitalization times/rates, the available evidence does not uniformly assert negative effects of increased distance.The objectives of this study were to describe the clinicopathologic features and treatment outcomes of childhood rhabdomyosarcoma in a resource-constrained setting. All cases of childhood rhabdomyosarcoma seen over a 10-year period (July 2006 to June 2016) at the University College Hospital, Ibadan, Nigeria were reviewed. Data were extracted from the database of the pediatric Hematology/Oncology Unit of the hospital and analyzed. Ethical approval was obtained from the Institutional Ethics Committee. Fifty children were seen comprising 30 men and 20 women with bimodal ages of 4 and 5 years. Median duration of illness was 16 weeks and the most common primary tumor site was the head-and-neck region in 27 (54%) of cases. The histologic subtypes were embryonal in 30 (60%), alveolar in 9 (18%), and not specified in 11 (22%). The Intergroup Rhabdomyosarcoma Study group TNM Pretreatment stages were stage I in 15 (30%), stage III in 17 (34%), and stage IV in 18 (36%). Treatment included chemotherapy, surgery, and radiotherapy and abandoned in 20 (40%) cases. Median survival was 45 weeks (95% confidence interval 16.4-73.6) and 5 (10%) patients were alive and disease free, 4 years or more after diagnosis. Outcome of childhood rhabdomyosarcoma is poor and early diagnosis and improved access to treatment are recommended.Children with sickle cell disease (SCD) face academic challenges because of direct and indirect disease-related events. This study examined the proportion of youth with SCD with educational plans and whether cognitive functioning is associated with educational support. Ninety-one youth (7 to 16 y) with SCD completed the WISC-V; caregivers reported educational support (504 Plan/Individualized Education Program) and completed the Behavior Rating Inventory of Executive Function. χ2 square and t test analyses explored whether overall intelligence (full-scale intelligence quotient [FSIQ]), relative weaknesses in processing speed and working memory (> 1SD below FSIQ), and parent-reported executive functioning were associated with educational plans. Participants with a FSIQ less then 90 were more likely to have support (74%) compared with youth with a FSIQ≥90 (47%; P=0.012). Those with FSIQ≥90 and FSIQ=80 to 89 were less likely to have support (47%, 58%, respectively) compared with those with FSIQ≤79 (89%; P=0.004). Relative weaknesses in processing speed were associated with educational support (83% vs. 52%, P=0.018) as well as behavioral aspects of executive functioning (Ps less then 0.05). Despite universal eligibility for a 504 Plan, 42% of youth with SCD in our sample did not have educational support. Significant deficits in intellectual functioning, processing speed, and parent-observed executive functioning are associated with having a plan, but children with subtle deficits seem less likely to be identified for educational support.

Functional variants of the cytotoxic T-lymphocyte antigen-4 (CTLA4) could contribute to the pathogenesis of disorders characterized by abnormal T-cell responses.

We report a case of a 13-year-old girl who first presented with polyarticular juvenile idiopathic arthritis poorly responsive to treatment. During the following years the patient developed cytopenias, chronic lymphoproliferation, high values of T-cell receptor αβ+ CD4- CD8- double-negative T cells and defective Fas-mediated T cells apoptosis. Autoimmune lymphoproliferative syndrome was diagnosed and therapy with mycophenolate mofetil was started, with good hematological control. Due to the persistence of active polyarthritis, mycophenolate mofetil was replaced with sirolimus. In the following months the patient developed hypogammaglobulinemia and started having severe diarrhea. Histologically, duodenitis and chronic gastritis were present. Using the next generation sequencing-based gene panel screening, a CTLA4 mutation was detected (p.Cys58Serfs*13).
