PURPOSE: Anthracyclines are a mainstay of the treatment of several childhood malignancies, but their utility is limited by dose-related cardiotoxicity. This study is aimed to explore the link between exposure of paediatric cancer patients to doxorubicin and its metabolite doxorubicinol, and cardiac troponin I (cTnI). METHODS: In a prospective pilot study plasma doxorubicin, doxorubicinol, and cTnI concentrations were measured in samples from children undergoing cancer chemotherapy...

Background: Ototoxicity is a common adverse side effect of platinum chemotherapy and cranial radiation therapy; however, individual susceptibility is highly variable. Therefore, the objective of this study was to conduct an epigenome-wide association study to identify differentially methylated CpG sites associated with ototoxicity susceptibility among cisplatin-treated pediatric patients with embryonal tumors. Methods: Samples were collected for a discovery (n=62) and a replication cohort (n=18) of medulloblastoma and primitive neuroectodermal tumor patients...

BACKGROUND: Patients with newly diagnosed high-risk (HR) neuroblastoma (NBL) still have a poor outcome, despite multi-modality intensive therapy. This poor outcome necessitates the search for new therapies, such as treatment with (131)I-meta-iodobenzylguanidine ((131)I-MIBG). OBJECTIVES: To assess the efficacy and adverse effects of (131)I-MIBG therapy in patients with newly diagnosed HR NBL. SEARCH METHODS: We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2016, Issue 3), MEDLINE (PubMed) (1945 to 25 April 2016) and Embase (Ovid) (1980 to 25 April 2016)...

In the context of ante-natally diagnosed hydronephrosis, the vast majority of children with a dilated renal pelvis do not need any surgical treatment, as the dilatation resolves spontaneously with time. Slow drainage demonstrated at Tc-99m-mercaptoacetyltriglycine (MAG3) renography does not necessarily mean obstruction. Obstruction is defined as resistance to urinary outflow with urinary stasis at the level of the pelvic-ureteric junction (PUJ) which, if left untreated, will damage the kidney. Unfortunately this definition is retrospective and not clinically helpful...

Proliferative Fasciitis (PF) is a benign lesion with histologic and clinical features overlapping with those of malignant soft tissue tumours. Its occurrence in children is considered very rare. We present a case of PF appearing as a painful, red, gradually increasing in size lesion, during a period of a few weeks, on the finger of a five-year-old boy compromising the dermis and subcutaneous tissue. We were able to locate literature on 20 paediatric PF cases, which we review. Only five of these focus on the clinical data, the rest describing mainly histological findings...

Pleuropulmonary blastoma (PPB) is a rare malignant intrathoracic tumor primarily affecting children under 5 years of age. PPBs are histologically divided into 3 subtypes: Type I PPBs are composed of multiple cysts, and type III is a solid lesion with a variable morphologic appearance. Type II has a mixed morphology consisting of cystic and solid areas. The genetics of PPB are poorly understood. We analyzed 16 cases of the Kiel Paediatric Tumor Registry with the diagnosis of PPB by comparative genomic hybridization and confirmed some genetic changes by fluorescence in situ hybridization...

AIM: This retrospective study reviewed the paediatric oral biopsies received over 10 years at a teaching hospital and dental college in India. It is important that paediatric dentists know the diagnostic tendencies of oral pathological conditions in children, and possess updated information for their diagnosis and treatment. METHODS: Biopsies of patients 17 years of age or younger were selected. Computerised data regarding age, gender, anatomic location, and histopathological diagnosis was retrieved and classified into nine categories...

WT1 is a transcription factor which regulates the epithelial-mesenchymal balance during embryonic development and, if mutated, can lead to the formation of Wilms' tumour, the most common paediatric kidney cancer. Its expression has also been reported in several adult tumour types, including breast cancer, and usually correlates with poor outcome. However, published data is inconsistent and the role of WT1 in this malignancy remains unclear. Here we provide a complete study of WT1 expression across different breast cancer subtypes as well as isoform specific expression analysis...

T-cell depleted (TCD) haploidentical transplantation is increasingly used in paediatric patients with haematological malignancies and donor selection is a challenge. We conclude that a simple criterion such as donor age should be also considered in depleted haploidentical setting because faster immune reconstitution is achieved using younger donors decreasing non-relapse related mortality.

Nowadays, allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a well-established treatment procedure and often the only cure for many patients with malignant and non-malignant diseases. Decrease in short-term complications has substantially contributed to increased survival. Therefore long-term sequelae are reaching the focus of patient care. One of the most important risks of stem cell transplant survivors is infertility. As well as in the field of allo-HSCT also the field of reproductive medicine has achieved substantial advances to offer potential options for fertility preservation in both boys and girls...

BACKGROUND: Allogeneic haemopoietic stem cell transplant (Allo-HSCT) is a specialised and costly intervention, associated with significant morbidity and mortality. It is used to treat a broad range of paediatric conditions. South Africa (SA) is an upper middle-income country with limitations on healthcare spending. The role of paediatric Allo-HSCT in this setting is reviewed. OBJECTIVES: To review paediatric patients who underwent Allo-HSCT at the Groote Schuur Hospital/University of Cape Town Private Academic Hospital transplant unit in Cape Town, South Africa, and received post-transplant care at Red Cross War Memorial Children's Hospital, over the period January 2006 - December 2014 in respect of indications for the transplant, donor sources, conditioning regimens, treatment-related morbidity and overall survival (OS)...

INTRODUCTION: Cancer is the leading cause of death between the first year of life and adolescence, and some types of diseases are still a major challenge in terms of cure. There is, therefore, a major need for new drugs. Recent findings in cancer biology open the door to the development of targeted therapies against individual molecular changes, as well as immunotherapy. Promising results in adult anti-cancer drug development have not yet been translated into paediatric clinical practice...

BACKGROUND: Primary care physicians (General Practitioners (GPs)) play a pivotal role in providing end of life care (EoLC). However, many lack confidence in this area, and the quality of EoLC by GPs can be problematic. Evidence regarding educational needs, learning preferences and the acceptability of evaluation methods is needed to inform the development and testing of EoLC education. This study therefore aimed to explore GPs' EoLC educational needs and preferences for learning and evaluation...

Ewing sarcoma/primitive neuroectodermal tumor (PNET) is a high-grade malignant neoplasm commonly affecting bones of the thoracic region. Primary Ewing sarcoma/PNET of the kidney is exceptional; it commonly affects young adults and is rarely reported in children. Here we describe a case of renal PNET in a 10-year-old girl who presented at our institute with haematuria and abdominal lump. Computer tomography scan revealed a huge mass in the right kidney. Computer tomography-guided aspiration from the mass showed cytomorphological features of a small blue round cell tumor...

PURPOSE: Paediatric recipients of haematopoietic stem cell transplantation (HSCT) have a high risk for invasive fungal infections. Posaconazole oral suspension has proven to be effective in antifungal prophylaxis in adult and paediatric patients. A new posaconazole tablet formulation with absorption independent of the gastric conditions was approved by the FDA in 2013. This is the first report on the use of posaconazole tablets in paediatric patients. METHODS: This single-centre study included 63 paediatric patients with haemato-oncological malignancies who received posaconazole for antifungal prophylaxis after HSCT...

Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumour in children and adolescents. Histologically RMS resembles developing fetal striated skeletal muscle. RMS is stratified into different histological subtypes which appear to influence management plans and patient outcome. Importantly, molecular classification of RMS seems to more accurately capture the true biology and clinical course and prognosis of RMS to guide therapeutic decisions. The identification of PAX-FOXO1 fusion status in RMS is one of the most important updates in the risk stratification of RMS...

INTRODUCTION: Awareness for paediatric palliative care has resulted in the impetus for paediatrician-led palliative care services across Malaysia. However, there is paucity of local data on patients receiving hospital-based paediatric palliative care. We aim to review the clinical spectrum of patients referred to these services. METHODS: An observational study of children aged between 0-18 years receiving palliative care at 13 hospitals between 1st January and 31st December 2014 was carried out...

INTRODUCTION: Leydig cell hyperplasia (LCH) and Leydig cell tumours (LCTs) in children are rare, typically presenting with precocious puberty. Previously, orchidectomy was the routine management; however, more recently, testis-sparing surgery has been performed with good results. We present a series of unusual presentations of LCH, raising new management questions, and a review of the literature regarding LCH and LCT in children. STUDY DESIGN: We performed a literature search using Ovid Medline, PubMed, and Google Scholar, producing 456 articles...

BACKGROUND: Alteration of DNA methylation (5-methylcytosine, 5mC) patterns represents one of the causes of tumorigenesis and cancer progression. Tet proteins can oxidise 5mC to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine and 5-carboxylcytosine (5caC). Although the roles of these oxidised forms of 5mC (oxi-mCs) in cancer pathogenesis are still largely unknown, there are indications that they may be involved in the mechanisms of malignant transformation. Thus, reduction of 5hmC content represents an epigenetic hallmark of human tumours, and according to our recent report, 5caC is enriched in a proportion of breast cancers and gliomas...
