RESUMO
Nasopharyngeal carcinoma (NPC) is a rare and locally aggressive form of childhood cancer. Treatment of pediatric NPC includes chemotherapy and radiotherapy. Most studies on the treatment of pediatric NPC are single-arm studies. With current treatment protocols survival rates for patients with nonmetastatic disease exceed 80%, although most children will have long-term treatment-related late effects. Efforts to reduce early and late toxicities include reduced radiotherapy doses in children with good responses to induction chemotherapy. Further studies are needed to evaluate the role of immunotherapy in both the primary setting and in children with progressive or relapsed disease. This review summarizes current clinical approaches to the treatment of pediatric NPC.

Children with congenital or acquired asplenia or hyposplenism have an increased risk for severe and even life-threatening infections mainly due to encapsulated bacteria. Current practice focuses on preventing severe infections with timely administration of vaccinations, antibacterial prophylaxis when indicated, and urgent evaluation and treatment of febrile events. As new vaccines are now available for both children and adults with asplenia/hyposplenism, we present an up-to-date recommendation on the prevention and management of acute infections in children with asplenia/hyposplenism.

In this retrospective study spanning 2016 to 2022, we aimed to evaluate the diagnostic utility of upper gastrointestinal endoscopy (UGE) in children under 18 years presenting with severe unexplained iron deficiency anemia (IDA), defined as microcytic anemia of hemoglobin ≤7 g/dL with low ferritin levels. Of 106 children hospitalized for severe anemia, 29 had unexplained IDA (mean hemoglobin level of 6.2 [3.2 to 6.9] gr/dL), and 25 of them underwent UGE. The mean age was 10.7 ± 3.9 years, with 76% being female. Ten children (40%) had gastrointestinal (GI) symptoms at presentation. The cause of IDA was found in 18 (72%) of 25 children who underwent UGE, of whom 12 were without GI symptoms. Gastric nodularity, erosions, or polyps were observed in 68%, and gastritis was evident in 72% based on histopathology. Helicobacter pylori was found in 50% of those with gastritis. Follow-up showed normalized hemoglobin levels in 92% of cases, with only 2 children requiring repeat iron therapy. Our findings underscore the importance of incorporating UGE into the diagnostic investigation of severe unexplained IDA in children, irrespective of the presence of GI symptoms.
