INTRODUCTION: Epileptic encephalopathies in infancy are defined as conditions where the sustained epileptic activity itself may contribute to the severe neurological and cognitive impairment. These epileptic encephalopathies include Ohtahara syndrome, early myoclonic epileptic encephalopathy, West syndrome, Dravet syndrome, and malignant migrating epilepsy in infancy. These syndromes result from identifiable primary causes, such as structural, neurodegenerative, metabolic, or genetic defects...

Longitudinal melanonychia is not frequently observed in children, and few studies exist on longitudinal melanonychia in paediatric patients, especially in Asian populations. We aimed to evaluate the clinical and histological findings of longitudinal melanonychia in Korean paediatric patients. A retrospective review of paediatric patients (≤18 years old) with longitudinal melanonychia who underwent nail biopsy between January 2010 and October 2015 was performed. Of a total of 21 patients with longitudinal melanonychia, there were 10 cases of functional melanonychia, eight of lentigo, and three of nevus, as determined by microscopic examination...

Wilms tumour is named after Max Wilms. It is an embryonal tumour derived from the metanephros. It is the commonest childhood renal tumour and the third commonest paediatric malignancy. Synchronous bilateral Wilms tumours (BWT) represent 4-7% of all Wilms tumours (WT) and present at a younger age than unilateral Wilms tumours. At least 10% of synchronous BWTs have unfavourable histology, and up to 22% are associated with genitourinary abnormalities, aniridia, WAGR syndrome, Denys-Drash syndrome, hemihypertrophy, or one of the other overgrowth syndromes...

In the past decade, the landscape of drug development in oncology has evolved dramatically; however, this paradigm shift remains to be adopted in early phase clinical trial designs for studies of molecularly targeted agents and immunotherapeutic agents in paediatric malignancies. In drug development, prioritization of drugs on the basis of knowledge of tumour biology, molecular 'drivers' of disease and a drug's mechanism of action, and therapeutic unmet needs are key elements; these aspects are relevant to early phase paediatric trials, in which molecular profiling is strongly encouraged...

INTRODUCTION: Diffusion-weighted MR imaging (DWI) has demonstrated a great potential to help distinguish benign from malignant tumours in paediatric body. Our purpose is to evaluate whether DWI allow discrimination of thoracoabdominal neuroblastic tumours of various histological types and differentiation grades. METHODS: We retrospectively analysed DWI scans of the thoracoabdominal neuroblastic tumours in 25 children (11 girls, 14 boys). DWI was performed with two b-values of 0 and 800 s/mm(2) on a 3...

BACKGROUND: Advances in cancer treatment have led to improved long term survival after childhood cancer, but often at a price of impaired future fertility. Fertility Preservation (FP) in male children and early adolescents poses unique challenges as efficacy is unproven. OBJECTIVES: To describe characteristics of testicular tissue cryopreservation (TTCP) specimens taken from paediatric and adolescent patients, stratified by age, and prior chemotherapy, if any, and to demonstrate evidence for germ cells MATERIALS AND METHODS: Retrospective review of gonadal biopsies and clinical records of patients consented into the Royal Children's Hospital FP program between 1987-2015...

BACKGROUND: Leukaemia represents 30-40% of all paediatric malignant tumours and is the main cause of death in patients aged <15 years. One of the main complications in these patients is infection, which may often occur in the oral cavity. Chemotherapy-related oral health problems may be reduced by oral healthcare strategies based on the International Caries Detection and Assessment System (ICDAS) and Caries Management by Risk Assessment (CABRA). CASE REPORT: A case is reported of a 14-year-old girl treated for leukaemia who presented with established dental caries lesions which were classified and treated according to ICDAS and CABRA protocols...

BACKGROUND: Survival of childhood, adolescent and young adult (CAYA) cancers has increased with progress in the management of the treatments and has reached more than 80% at 5 years. Nevertheless, these survivors are at great risk of second cancers and non-malignant co-morbidities in later life. DeNaCaPST is a non-interventional study whose aim is to organize a national screening for thyroid cancer and breast cancer in survivors of CAYA cancers. It will study the compliance with international recommendations, with the aim, regarding a breast screening programme, of offering for every woman living in France, at equal risk, an equal screening...

REVIEW
Chandala Chitguppi, Tripti Brar
Oral submucous fibrosis in children is one of the devastating consequences of arecanut addiction in children. Arecanut is the fourth commonest psychoactive agents used worldwide. However, regrettably, unlike other addictions like tobacco and alcohol, its use in children has become socially acceptable atleast in a few countries. Consequently, children as young as two years have been noticed to be addicted to arecanuts. It has been a menace in most Asian countries and with increasing population migration, this has picked up even in the west...

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...

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.
