BACKGROUND AND OBJECTIVE: Patients with thalassaemia major (TM) and sickle cell disease (SCD) in Spain have been counted since the creation of the Spanish registry of haemoglobinopathies (REHem). The objective of this paper is to update the published data after the increase in cases due to the inclusion of adults and introduction of new-born screening in almost the whole country. MATERIAL AND METHODS: An observational, descriptive, multicentre and ambispective study that included patients with haemoglobinopathies registered in the REHem, started in January 2014 and followed up annually...

Despite being a rare disease, cancer is the first cause of mortality due to disease during the paediatric age in the developed countries. The current, great increase in new treatments, such as immunotherapy, constitutes a new clinical and regulatory paradigm. Cellular immunotherapy is one of these types of immunotherapy. In particular, the advanced therapy drugs with chimeric antigen receptors in the T-lymphocytes (CAR-T), and particularly the CAR-T19 cells, has opened up a new scenario in the approach to haematology tumours like acute lymphoblastic leukaemia and the B-Cell lymphomas...

Patients given allogeneic hematopoietic stem cell transplantation (alloHSCT) present an increased incidence of long-term toxicities that can be attributed to the preparative regimen. We retrospectively analyzed in a population of 670 children receiving allo-HSCT for acute leukemia the occurrence of different late effects in function of the choice made between total body irradiation (TBI) and busulfan, as part of the preparative regimen. In univariable analysis, we found that patients treated with TBI developed cataract in 24% of the cases compared with 4% in patients treated with BU (p = 0...

Neonatal jaundice may be due to different causes, ranging from physiological conditions to severe diseases. In term neonates with persistent jaundice beyond 14 days of life, it should be determined whether hyperbilirubinemia is unconjugated or conjugated, in order to study the etiology and start early treatment. In the majority of cases, conjugated hyperbilirubinemia (cholestasis) is a sign of liver dysfunction possibly associated with alterations in the bile flow secondary to structural or molecular abnormalities of the liver and/or the biliary tract...

Oral ferrous salts are standard treatment for children with iron deficiency anemia (IDA). The objective of our study was to monitor oral iron therapy in children, aged 3 months-12 years, with IDA. We prospectively collected clinical and hematological data of children with IDA, from 15 AIEOP (Associazione Italiana di Ematologia ed. Oncologia Pediatrica) centers. Response was measured by the increase of Hb from baseline. Of the 107 analyzed patients, 18 received ferrous gluconate/sulfate 2 mg/kg (ferrous 2), 7 ferrous gluconate/sulfate 4 mg/kg (ferrous 4), 7 ferric iron salts 2 mg/kg (ferric), 62 bis-glycinate iron 0...

BACKGROUND: Malignant germ cell tumors (GCTs) are a heterogeneous group of rare neoplasms in children. Optimal outcome is achieved with multimodal therapies for patients with both localized and advanced disease, especially after the introduction of platinum-based chemotherapy regimens. In this respect, data on salvage treatment for children with relapsed or platinum-refractory disease are still limited. METHODS: Retrospective analysis of data regarding patients affected by malignant GCTs with platinum-refractory or relapsed disease after first-line treatment according to AIEOP TCGM 2004 protocol was conducted...

BACKGROUND: Malnutrition at admission of paediatric hospitalization is a risk factor for negative evolution and is associated with increased morbidity and mortality. The main objective was to learn about the frequency of malnutrition and undernourishment as well as the nutritional risk at hospital admission, through a sample of paediatric patients. MATERIAL AND METHODS: A descriptive cross-sectional was taken, chosen from long term patients in Hospital Dr. Humberto Notti...

INTRODUCTION: Severe sepsis (SS) is one of the leading causes of pediatric mortality in Argentina. The objective was to describe the epidemiological characteristics and to analyze risk factors associated with mortality from SS among patients hospitalized in pediatric intensive care units (PICU) in Argentina. POPULATION AND METHODS: Observational, prospective cohort study among patients with SS hospitalized in PICUs in Argentina from 8/1/2008 to 9/30/2008. RESULTS: Two thousand five hundred and fifty nine patients were admitted at 59 PICUs...

Purpose: To describe how the provision of services for adolescents with cancer has evolved in Italy, the study evaluated access to pediatric oncology centers affiliated to the national cooperative group Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP), and the development of dedicated local projects. Methods: We calculated the observed/expected (O/E) ratio of adolescent patients (15-19 years old) admitted to AIEOP centers during the years 2013-2017. Observed cases were obtained from the AIEOP database (model 1...

Objective: Following the notable work accomplished by the Mexican Association of Specialists in Congenital Heart Disease (Asociación Mexicana de Especialistas en Cardiopatías Congénitas) with the development of a national registry for congenital cardiac surgery, the World Society for Pediatric and Congenital Heart Surgery has implemented an international platform to collect data and analyze outcomes of children with congenital heart disease. Methodology: This manuscript proposes a possible collaboration between Mexico's national congenital cardiac database (Registro Nacional de Cirugía Cardíaca Pediátrica) and the World Database for Pediatric and Congenital Heart Surgery...

Purpose: Adolescents (15-19 years) with soft tissue sarcomas (STS) have worse survival than children. One reason is the former's limited access to expert centers. We investigated where adolescents with STS are treated in Italy, analyzing hospital discharge records (HDRs) countrywide. Methods: We applied to the Health Ministry to obtain the HDRs of all adolescents hospitalized in 2002-2015. We excluded prevalent cases hospitalized with STS in 2002-2006 to obtain a cohort of incident cases 2007-2014. We defined main treatments observing 12 months from diagnosis...

BACKGROUND: Adolescents (aged 10-17 years) with acute lymphoblastic leukaemia (ALL) have unfavourable disease features and an inferior outcome when compared with younger children, but it is still unclear if differences in disease biology and prognosis exist between adolescents older or younger than 15 years. METHODS: We retrospectively analysed outcomes of 1094 adolescents with ALL, aged 10-17 years, treated within the AIEOP-BFM ALL 2000 trial, overall and by the age groups 10-14 and 15-17 years...

BACKGROUND: As a significant proportion of relapses occurred in the tumor bed or abdomen on patients with the fifth National Wilms Tumor Study stage I anaplastic Wilms tumor (WT), flank radiotherapy was added for stage I anaplastic WT in the subsequent study of the Children's Oncology Group (AREN0321). Preliminary results revealed reduction of relapse rate and improved survival. In cases treated with preoperative chemotherapy, such as in International Society of Pediatric Oncology (SIOP), the value of radiotherapy has never been studied...

INTRODUCTION: There are discrepancies in the diagnosis and management of cow's milk protein allergy (CMPA) in Spain and Latin America.

INTRODUCTION: Cancer and blood disorders in children are rare. The progressive improvement in survival over the last decades largely relies on the development of international academic clinical trials that gather the sufficient number of patients globally to elaborate solid conclusions and drive changes in clinical practice. The participation of Spain into large international academic trials has traditionally lagged behind of other European countries, mainly due to the burden of administrative tasks to open new studies, lack of financial support and limited research infrastructure in our hospitals...
