How Did Adolescents With Cancer Experience the COVID-19 Pandemic? A Report From Italian Pediatric Hematology Oncology Association Centers.

Purpose: This study set out to evaluate the psychosocial effects of coronavirus disease 2019 (COVID-19) among adolescents with cancer, and whether these effects are significantly different among adolescents who were undergoing therapy or had completed it.

Materials And Methods: The AIEOP Adolescents Working Group and the AIEOP Psychosocial Working Group adapted a questionnaire, which was completed by 214 adolescent cancer patients ( Mage =16.3 y, range: 15 to 19 y old) treated at 16 AIEOP centers in the North (38%), South (31%), and Center (31%) of Italy.

Outcomes after Unrelated Umbilical Cord Blood Transplantation for Children with Osteopetrosis.

Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for most children with osteopetrosis (OP). Timing of HSCT is critical; therefore, umbilical cord blood transplantation (UCBT) is an attractive option. We analyzed outcomes after UCBT in 51 OP children.

The diagnostic challenge of very early-onset enterocolitis in an infant with XIAP deficiency.

Background: Aggressive course and resistance to treatments usually characterize very early onset inflammatory bowel disease (VEO-IBD). Some VEO-IBD cases are due to monogenic immune defects and can benefit from hematopoietic stem cell transplantation (HSCT).

Case Presentation: We describe a Caucasian male baby who presented in the first months of life macrophage activation syndrome, followed by intractable colitis, recurrent episodes of fever and mild splenomegaly.

Two pregnancies shortly after transplantation with reduced intensity conditioning in chronic myeloid leukemia.

POI is a relevant late complication after HSCT and occurring more frequently after MAC than after RIC regimens. Reports on the frequency of POI after RIC in a large pediatric and adolescent population are lacking. In this study, we describe a girl affected by CML diagnosed at the age of 15 yr and treated with oncarbide and interferon followed by imatinib and dasatinib.

Paediatric reduced intensity conditioning: analysis of centre strategies on regimens and definitions by the EBMT Paediatric Diseases and Complications and Quality of Life WP.

The aim of this analysis was to explore the diversity of reduced intensity conditioning (RIC) in paediatric allo-SCT in daily practice across Europe. Data from the European Group for Blood and Marrow Transplantation (EBMT) Promise database from 1994 to 2008 were supplemented by a survey of EBMT centres performing paediatric allo-SCT on the current policy asking for the underlying diseases and for the drug combinations. Records from 161 centres from 30 countries were analysed and 139 various RIC regimens were reported.

Autoimmune hematological diseases after allogeneic hematopoietic stem cell transplantation in children: an Italian multicenter experience.

Autoimmune hematological diseases (AHDs) may occur after allogeneic hematopoietic stem cell transplantation (HSCT), but reports on these complications in large cohorts of pediatric patients are lacking. Between 1998 and 2011, 1574 consecutive children underwent allogeneic HSCT in 9 Italian centers. Thirty-three children (2.

Acute graft-versus-host disease in pediatric allogeneic hematopoietic stem cell transplantation. Single-center experience during 10 yr.

a-GvHD may complicate allogeneic HSCT. In this retrospective single-center study, we evaluated incidence and risk factors of a-GvHD in 197 consecutive allogeneic pediatric HSCTs applying Glucksberg and NIH a-GvHD classifications. Among 179 eligible transplants, the cumulative incidence of grade 0-I a-GvHD was 48% and grade II-IV was 52%.

Mycobacterium tuberculosis pneumonia and bacteremia after allogeneic hematopoietic stem cell transplant: report of an instructive pediatric case.

Pulmonary infections often complicate hematopoietic stem cell transplantation (HSCT) outcome. Uncommon aetiologies, like Mycobacterium tuberculosis, should be considered when the clinical conditions do not fully improve with standard antimicrobial therapy and microbiological evaluations are repeatedly negative for bacteria and fungi. We describe an interesting pediatric case of miliary lung tuberculosis after HSCT, which was successfully treated after administering the appropriate therapy.

Magnetic resonance imaging in childhood leukemia survivors treated with cranial radiotherapy: a cross sectional, single center study.

Background: Children treated with cranial radiotherapy (CRT) for leukemia are at risk of developing central nervous system injuries. Magnetic resonance imaging (MRI) represents the examination method of choice for evaluating radiation-induced brain complications. The purpose of this report is to describe the spectrum of MRI abnormalities detected in a group of survivors of leukemia treated with cranial irradiation.

Enhancing cranial nerves and cauda equina: an emerging magnetic resonance imaging pattern in metachromatic leukodystrophy and krabbe disease.

We report on three cases of infantile Krabbe disease and one case of infantile metachromatic leukodystrophy showing magnetic resonance (MR) imaging findings of diffuse and coexistent cranial nerve and cauda equina nerve roots enhancement. Such findings may be simultaneous, or even precede, typical white matter abnormalities and, in the appropriate clinical context, may facilitate an earlier diagnosis. There is a rational for the use of contrast agents and craniospinal MR imaging during the first imaging of children with a history of psychomotor regression and clinical evidence of peripheral nerve involvement to exclude differential diagnoses.

HHV-8-related visceral Kaposi's sarcoma following allogeneic HSCT: report of a pediatric case and literature review.

An HHV-8-related visceral KS was diagnosed in a 10-yr-old boy after partially matched allogeneic HSCT. This complication occurred 463 days after HSCT and involved tonsils, lymph nodes, hard palate, lung, skin, and paranasal sinuses. Treatment with pegylated liposomal doxorubicin induced long-term remission (33 months) of this disease.

Viral-load and B-lymphocyte monitoring of EBV reactivation after allogeneic hemopoietic SCT in children.

EBV-associated post transplant lymphoproliferative disease (EBV-PTLD) is a life-threatening complication that may occur after hemopoietic SCT. We prospectively screened 80 children on a weekly basis using nested quantitative PCR to evaluate EBV genome copies. EBV viral load <1000 copies per 10(5) PBMC was observed in 63% of transplants, whereas it was between 1000 and 9999 copies per 10(5) PBMC in 13%, and between 10 000 and 19 999 in 10%, with no significant increase in percentage of CD20+ lymphocytes.

Assessing the risk of transplant-related complications and individually tailoring the HSCT procedure in children and adolescents--is it possible?

Children surviving after haematopoietic SCT (HSCT) are a growing population that need to keep their health status under control. They may experience early and late complications that are related to transplant procedures and to treatments administered before HSCT. Monitoring transplant-related complications is mandatory, especially during the child's growth.

Non-endocrine late complications in children after allogeneic haematopoietic SCT.

Non-endocrine events represent a heterogeneous group of complications occurring in children who survive long term after haematopoietic SCT. This review highlights the late sequel in a growing child. The preparative regimen itself with high-dose chemotherapy and/or radiotherapy (TBI) or the treatment given before the transplant procedure may cause organ damage with permanent sequel.

Early complications following haematopoietic SCT in children.

Early complications can be defined as those occurring within 100 days after transplant. Both epithelial and endothelial damage represent the pathogenetic basis for the onset of the most frequent complications. Clinical features related to endothelial damage depend on the involved district or on the grade and type of general distribution.

Three consecutive related bone marrow transplants for juvenile myelomonocytic leukaemia.

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is the only cure for juvenile myelomonocytic leukaemia (JMML), but relapse remains the major cause of failure. A second transplant may be considered a way to induce the graft vs. leukaemia effect in patients who relapse after their first HSCT.

Surgery for acute graft-versus-host disease of the bowel: description of a pediatric case.

Gastrointestinal acute graft-versus-host disease (GI-aGvHD) is still a common complication of allogeneic stem cell transplantation. Surgical management is an unusual approach, reserved for patients with intestinal occlusion, severe profuse rectal bleeding, or both. The authors describe a child with severe GI-aGvHD who did not respond to common immunosuppressive drugs and procedures and therefore underwent subtotal colectomy due to untreatable rectal bleeding.

Mesial temporal sclerosis--a late complication in four allogeneic pediatric recipients with persistent seizures after an acute episode of cyclosporine-A neurotoxicity.

Mesial temporal sclerosis (MTS) is a common finding in patients with intractable temporal lobe epilepsy (TLE). In this report, we retrospectively reviewed the neuroimaging results of four children who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), and who developed recurrent, partial, intractable seizures following a first event caused by cyclosporine-A (CSA) neurotoxicity. Neuroradiologic findings of MTS were demonstrated in all these patients.

Severe neurologic complications after hematopoietic stem cell transplantation in children.

Objective: To describe and evaluate the incidence and risk factors of severe neurologic events (SNE) in pediatric recipients of allogeneic or autologous hematopoietic stem cell transplantation (HSCT) for hematologic or nonhematologic diseases.

Methods: Retrospective analysis of 272 consecutive children admitted to the G. Gaslini Children's Research Institute and given HSCT (70 from unrelated donors, 115 from related donors, and 87 autologous) between June 1985 and January 2001.

Fiberoptic bronchoscopy and bronchoalveolar lavage for the evaluation of pulmonary infiltrates after BMT in children.

Thirty-one fiberoptic bronchoscopies and BAL performed within 4 days after the appearance of pulmonary infiltrates in 28 children who received BMT were reviewed. A causative agent was identified in 67% of patients with diffuse infiltrates (Cytomegalovirus in 8 cases, Pneumocystis carinii in 4) and in 31% of those with localized infiltrates (Aspergillus in 2, bacteria in 2). No relevant side effect was reported.

Wilms' tumor arising in a multicystic kidney.

We describe a child with Wilms' tumor (WT) which occurred in an unequivocal multicystic dysplastic kidney (MDK). We indicate a current nonsurgical approach to MDK, but stress the probable malignant degeneration of blastemal cells, the need to search carefully for the WT in the MDK, and the necessity on 3-monthly follow-up US studies.

Relapsing polychondritis in childhood: a rare observation studied by CT and MRI.

Relapsing polychondritis is very rare in children. The diagnosis must be based on a combination of clinical and pathologic features. CT is very useful for an accurate and rapid assessment of laryngo-tracheo-bronchial involvement and the typical finding is lumen narrowing by wall thickening and collapse of the supporting cartilaginous structures.
