The Triad of COVID-19 in Children: Acute COVID-19, Multisystem Inflammatory Syndrome, and Long COVID-Part I.

The coronavirus disease 2019 (COVID-19) originated in Wuhan, China, in late 2019. Within a span of a few months, it was deemed a global pandemic by the World Health Organization. It was first thought to affect the adult population, but soon after, cases of COVID-19 in children started emerging.

Checkpoint Immunotherapy in Pediatric Oncology: Will We Say Checkmate Soon?

Immune checkpoint inhibitors (ICIs) are a relatively new class of immunotherapy which bolsters the host immune system by "turning off the brakes" of effector cells (e.g., CTLA-4, PD-1, PD-L1).

Targeted Therapies in Pediatric Acute Myeloid Leukemia - Evolving Therapeutic Landscape.

Acute myeloid leukemia (AML) accounts for 25% of all leukemia diagnosis and is characterized by distinct cytogenetic and molecular profile. Advances in the understanding of the causative driver mutations, risk-based therapy and better supportive care have led to an overall improvement in survival with frontline therapy. Despite these improvements, a significant number fail either because of primary refractory disease to the conventional 7+3 combination of anthracyclines and cytosine arabinoside (Cytarabine; Ara-C) or experience relapse post remission.

Curing childhood cancer the "Natural" Way: Nature as the source of chemotherapy agents.

For many centuries, products of natural origin from plants, marine, microbes and soil micro-organisms have been studied by numerous researchers across the world to yield many of the chemotherapeutic agents we use in this modern era. There has been a tremendous gain in knowledge from various screening and separating techniques which led to the discovery of biologically active small molecules from natural products. Preclinical studies testing the antitumor activities of these agents against tumor cell lines and xenograft animal models were the gateway to the clinical trials in humans leading to the approval of these agents that are in clinical use today.

The Impact of COVID-19 on Pediatric Malignancy Diagnosis and Treatment: Never the Same but Lessons Learned.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic affected the pediatric oncology population globally. Over the course of 2 years, increasing reports have been made to better understand this entity and its pathologic complications on these patients. The pandemic has allowed healthcare providers, hospital systems, and leading oncologic societies to quickly adapt and formulate new guidelines for the effective understanding, management, and treatment of patients with pediatric malignancy.

Pineal Parenchymal Tumor of Intermediate Differentiation and DICER1 Syndrome: A Case Report.

DICER1 syndrome is a rare inherited tumor predisposition syndrome associated with an increased risk for several malignant and benign tumors. We present a patient with pineal parenchymal tumor of intermediate differentiation who was found to have a germline pathogenic variant in DICER1 gene. Pineoblastoma is a known DICER1-related tumor; however, the association between pineal parenchymal tumor of intermediate differentiation and DICER1 mutation is rare with only 1 recent large molecular study that has reported this association.

The paradox of Myeloid Leukemia associated with Down syndrome.

Children with Down syndrome constitute a distinct genetic population who has a greater risk of developing acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) compared to their non-Down syndrome counterparts. The risk for developing solid tumors is also distinct from the non-Down syndrome population. In the case of myeloid leukemias, the process of leukemogenesis in Trisomy 21 begins in early fetal life where genetic drivers including GATA1 mutations lead to the development of the preleukemic condition, transient abnormal myelopoiesis (TAM).

Juvenile Xanthogranuloma of the Pancreas in a Pediatric Patient Mimicking Pancreatic Neoplasm With High CA 19-9: Case Report and Literature Review.

Juvenile xanthogranuloma (JXG) is a rare, non-Langerhans cell histiocytosis. It is usually a benign and self-limiting condition. The most common sites are skin and soft tissue.

Higher daily doses of caffeine lowered the incidence of moderate to severe neurodevelopmental disabilities in very low birth weight infants.

Aim: We determined the influence of cumulative dosing of caffeine citrate on the neurodevelopmental outcomes of low birth weight (VLBW) infants at 18-22 months of postmenstrual age.

Methods: This retrospective chart analysis was conducted at Detroit Medical Center, Michigan, USA. The 181 infants we included were born between January 2006 and December 2016, were less than 32 weeks of gestational age and weighed less than 1500 grams.

Effect of early caffeine on neurodevelopmental outcome of very low-birth weight newborns.

Objectives: The objective of this study is to evaluate the effect of early caffeine therapy started within the first 48 h of life on neurodevelopmental outcome in very low birth weight (VLBW) newborns.

Study Design: VLBW newborns received either caffeine therapy within first 48 h of life (Early group), after 3rd day of life (Late group) or no caffeine during first month of life as per clinical team. A cohort of these newborns (n = 160) who survived were evaluated using Bayley Scale of Infant Development III (BSID III) developmental testing between 18 and 22 months of corrected age.
