Recommendations for the use of nuclear medicine imaging in patients with neuroblastoma.

Neuroblastoma (NB) is the most common extracranial solid cancer in children. Despite intensive multimodality treatment, long-term survival of patients with high-risk NB, which comprises more than half of all cases, remains poor. Nuclear medicine is key in diagnosis, staging, response assessment and long-term follow-up of NB.

Congenital metastatic neuroblastoma with placental involvement as a rare cause of non-immune fetal hydrops.

Non-immune hydrops fetalis represents the end-stage status of a variety of diseases, including metastatic tumors. We report a case of non-immune hydrops fetalis associated with multiple disseminated echogenic nodular lesions detected by ultrasound and confirmed by magnetic resonance. Cordocentesis demonstrated anemia and thrombopenia.

Prospects and Advances in Adoptive Natural Killer Cell Therapy for Unmet Therapeutic Needs in Pediatric Bone Sarcomas.

Malignant bone tumors are aggressive tumors, with a high tendency to metastasize, that are observed most frequently in adolescents during rapid growth spurts. Pediatric patients with malignant bone sarcomas, Ewing sarcoma and osteosarcoma, who present with progressive disease have dire survival rates despite aggressive therapy. These therapies can have long-term effects on bone growth, such as decreased bone mineral density and reduced longitudinal growth.

Therapeutic strategies and clinical evolution of patients with infantile fibrosarcoma: a unique paediatric case series.

Background: Infantile fibrosarcoma is the most frequent soft tissue sarcoma in newborns or children under one year of age. This tumour often implies high local aggressiveness and surgical morbidity. The large majority of these patients carry the ETV6-NTRK3 oncogenic fusion.

Treatment of infantile fibrosarcoma associated to an abdominal aortic aneurysm with larotrectinib: a case report.

Infantile fibrosarcoma (IFS) is a rare pediatric tumor which often presents the gene fusion. encodes the neurotrophin-3 growth factor receptor tyrosine kinase, a druggable therapeutic target. Selective tropomyosin receptor kinase (TRK) inhibitors, such as larotrectinib, have shown efficacy and safety in the treatment of IFS.

Acute Terminal Ileitis in Children: A Retrospective Study in a Pediatric Emergency Department.

Objectives: This study aims to describe the clinical presentation and outcome of patients diagnosed with acute ileitis in our pediatric emergency department.

Methods: We performed a retrospective study of all patients diagnosed with terminal ileitis by abdominal ultrasonography findings in our pediatric emergency department, over the years 2013 and 2014. Patients with previous diagnosis of inflammatory bowel disease (IBD) were excluded.
