Even though chemotherapy-induced nausea and vomiting (CINV) rarely become life-threatening, they are regarded by patients as one of the most unbearable complications and can often cause great suffering. CINV may also be an aggravating factor for other complications and pathological conditions. The currently available antiemetic prophylaxis can greatly reduce the incidence of CINV in children and adolescents receiving cancer treatment. However, inadequate management of CINV is still much more common in children than in adults, and the integration of new antiemetic drugs into pediatric care is delayed because of specific regulatory requirements for drug studies in children. The aim of this article is to present current standards for prevention and treatment of CINV in children and adolescents as well as to suggest ways to improve them.
Aneurysmal bone cyst (ABC) and telangiectatic osteosarcoma (TOS) share a lot of similarities in terms of the initial clinical presentation, the radiological semiotics and even the morphological pattern, however, they are completely different nosological entities requiring absolutely different treatment approaches. This article reports a clinical case of TOS of the femur which developed 1.5 years after the treatment of ABC of the same location and presents an analysis of literature on the differential diagnosis of these diseases, the modern concept of the pathogenesis of ABC and the possibility of the transformation of ABC into TOS. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.
