Effect of the Use of Gnrh Analogs in Low-Grade Cerebral Glioma.

Low-grade gliomas are the most common brain tumors in children. This tumor type presents a wide range of clinical, histological, and biological behaviors. In recent years, an association between estrogens and progesterone and the development of tumors has been suggested.

A Dynamic Approach for Early Risk Prediction of Gram-Negative Bloodstream Infection and Systemic Inflammatory Response Syndrome in Febrile Pediatric Hemato-Oncology Patients.

Background: The aim of this study was to evaluate the usefulness of C-Reactive Protein (CRP), Procalcitonin (PCT), and Interleukine 6 (IL6) biomarkers in predicting the existence of high-risk episodes (HRE) during the first 24 h of fever in pediatric cancer patients. HRE were defined as the presence of Gram-negative bloodstream infections or Systemic Inflammatory Response Syndrome. Methods: The study included 103 consecutive fever episodes in 44 hemato-oncological pediatric patients, from whom samples for biomarkers were taken upon initial evaluation (CRP-1, PCT-1 and IL6-1) and then between 12 and 24 h afterward (CRP-2, PCT-2 and IL6-2).

[Experience with Denosumab in central giant-cell granuloma].

Introduction: Central Giant Cell Granuloma is an infrequent bone lesion located mainly in the maxillary bone. The main treatment is surgery with wide margins, so it sometimes causes great morbidity and esthetic al terations. Denosumab, a RANK-ligand inhibitor monoclonal antibody, has been presented as a valid therapeutic alternative in the treatment of these lesions.

Biomarkers and Fever in Children with Cancer: Kinetics and Levels According to Final Diagnosis.

We investigated the kinetics of CRP, PCT, IL-6 and MR-proADM in a cohort of consecutive febrile patients with cancer in order to test the hypothesis that higher plasma concentrations and the absence of a rapid decrease in peak values would be associated with disease severity. (1) Method: A prospective descriptive and analytical study of patients with cancer and fever (≤18 years of age) at a University Hospital was carried out between January 2018 and December 2019. Information collected: sex, age, diagnosis, date and symptoms at diagnosis and medical history.

[Ototoxicity in cancer survivors: experience and proposal of a surveillance protocol].

Introduction: Ototoxicity occurs in different percentages in patients after treatment with platinum-based chemotherapy or cranial radiation therapy. The aim of this study was to present experience in ototoxicity monitoring.

Material And Methods: A review was made of the registry of paediatric cancer patients referred to the Children's Hearing Loss Unit from 1999 to 2019.

Ambulatory High-dose Methotrexate Administration in Pediatric Osteosarcoma Patients at a Single Institution in Argentina.

Background: The purpose of this study was to evaluate the feasibility and safety of ambulatory high-dose methotrexate (HDMTX) administration with oral hydration, alkalinization, and leucovorin rescue. HDMTX (12 g/m) was given intravenously over 4 hours after urine alkalinization. Families and patients were instructed to continue ambulatory oral hydration and alkalinization to monitor urine pH and to adjust bicarbonate according to our institution's treatment algorithm.
