Immunotherapy approaches for the treatment of diffuse midline gliomas.

Diffuse midline gliomas (DMG) are a highly aggressive and universally fatal subgroup of pediatric tumors responsible for the majority of childhood brain tumor deaths. Median overall survival is less than 12 months with a 90% mortality rate at 2 years from diagnosis. Research into the underlying tumor biology and numerous clinical trials have done little to change the invariably poor prognosis.

Oncolytic HSV-1 G207 Immunovirotherapy for Pediatric High-Grade Gliomas.

Background: Outcomes in children and adolescents with recurrent or progressive high-grade glioma are poor, with a historical median overall survival of 5.6 months. Pediatric high-grade gliomas are largely immunologically silent or "cold," with few tumor-infiltrating lymphocytes.

Carriage With De Novo Macrolide-Resistance and Breakthrough Pneumonia.

pneumonia is prevalent in children and can be followed by upper airway carriage for months. Treatment of pneumonia with macrolides is widespread and can lead to the development of macrolide resistance. The clinical consequences of chronic carriage are unknown.

Oncolytic herpes simplex virus immunotherapy for brain tumors: current pitfalls and emerging strategies to overcome therapeutic resistance.

Malignant tumors of the central nervous system (CNS) continue to be a leading cause of cancer-related mortality in both children and adults. Traditional therapies for malignant brain tumors consist of surgical resection and adjuvant chemoradiation; such approaches are often associated with extreme morbidity. Accordingly, novel, targeted therapeutics for neoplasms of the CNS, such as immunotherapy with oncolytic engineered herpes simplex virus (HSV) therapy, are urgently warranted.

Roseomonas gilardii Bacteremia in a Patient With HbSβ0-thalassemia: Clinical Implications and Literature Review.

Roseomonas gilardii is a Gram-negative coccobacillus identified in immunocompromised pediatric patients. A 5-year-old male with a history of HbSβ thalassemia status postsurgical splenectomy presented to the emergency department with fever. Blood cultures grew R.

Safety and efficacy of oncolytic HSV-1 G207 inoculated into the cerebellum of mice.

Primary malignant central nervous system (CNS) tumors are the leading cause of childhood cancer-related death and morbidity. While advances in surgery, radiation, and chemotherapy have improved the survival rates in children with malignant brain tumors, mortality persists in certain subpopulations and current therapies are associated with extreme morbidity. This is especially true for children with malignant infratentorial tumors.

Outcomes in Mild to Moderate Isolated Thrombocytopenia.

Objectives: Incidental isolated mild to moderate thrombocytopenia is a frequent laboratory finding prompting a referral to pediatric hematology-oncology. We tested the hypothesis that patients with isolated asymptomatic mild thrombocytopenia would not progress to require an intervention from a pediatric hematologist-oncologist.

Methods: This is a 5-year retrospective review of 113 patients referred to pediatric hematology-oncology for isolated thrombocytopenia.
