Inhibition of DKK-1 by WAY262611 Inhibits Osteosarcoma Metastasis.

Osteosarcoma is the most common primary malignant bone tumor in childhood. Patients who present with metastatic disease at diagnosis or relapse have a very poor prognosis, and this has not changed over the past four decades. The Wnt signaling pathway plays a role in regulating osteogenesis and is implicated in osteosarcoma pathogenesis.

Osteosarcoma (OS) is the most common primary malignant bone tumor in childhood. Patients who present with metastatic disease at diagnosis or relapse have a very poor prognosis, and this has not changed over the past four decades. The Wnt signaling pathway plays a role in regulating osteogenesis and is implicated in OS pathogenesis.

Nuanced Management of a Skull Base Tumor in the Setting of Relapsed Acute Lymphoblastic Leukemia.

 Relapsed acute lymphoblastic leukemia (ALL) involving the central nervous system (CNS) is a significant issue that contributes to both morbidity and mortality. Given the poor outcomes in patients with CNS relapse, understanding how ALL involving intracranial relapse presents and is treated is critical. Here, we present a complex case of relapsed recurrent ALL in a pediatric patient.

Case Report: Treatment of the rare B-cell lymphoblastic lymphoma with scalp lesion using rotation flap.

Introduction: Leukemia is the most frequently occurring cancer in children, and lymphoblastic lymphoma (LBL) is a rare subtype. LBL are lymphoid neoplasms of B or T cell origin and are primarily treated with chemotherapy. Although cure rates among children are excellent, these patients must be monitored for relapse.

v-SYMPHONY career development series: A collaboration to enhance professional awareness for pediatric hematology oncology trainees.

Background: A recent survey of pediatric hematology oncology (PHO) physicians identified that a majority believe fellows are struggling to find jobs that align with their goals. Career development for trainees has historically been home institution-specific, limiting fellows' exposures to career path possibilities. The "virtual-Symposium of Pediatric Hematology/Oncology of New York (v-SYMPHONY)" instituted a tristate Career Development Series for PHO trainees to better address their needs and increase awareness of the variety of PHO career opportunities.

Can you hear me now? Tools for cultivating a culture of respect, value, and appreciation within pediatric hematology, oncology, and cellular therapy.

The American Society of Pediatric Hematology/Oncology (ASPHO) conducted a workshop "Can you hear me now? Cultivating a culture of respect, value, and appreciation within pediatric hematology/oncology" at their annual meeting in May 2022 in hopes of exploring how the members can enhance wellness in a climate of increasing diversity. Initiatives in the past have focused on personal care, but it has been widely shown that administrative and institutional driven initiatives are essential to create an environment of wellness. In this interactive workshop, we discovered that 22% of participants felt their institution does not instill a culture of respect.

Children and young adults hospitalized for severe COVID-19 exhibit thrombotic coagulopathy.

We report the clinical and laboratory coagulation characteristics of 27 pediatric and young adult patients (2 months to 21 years) treated for symptomatic COVID-19 at a children's hospital in the Bronx, New York, between March 1 and May 31, 2020. D-Dimer was > 0.5 μg/mL (upper limit of normal) in 25 (93%) patients at admission; 11 (41%) developed peak D-dimer > 5 μg/mL during admission.

The Utility of 18FDG PET/CT Versus Bone Scan for Identification of Bone Metastases in a Pediatric Sarcoma Population and a Review of the Literature.

Background: Outcome of patients with osteosarcoma (OS) and Ewing sarcoma (EWS) is dependent on presence of metastases. Imaging guidelines for OS and EWS include radiographs, computed tomography (CT), and magnetic resonance imaging for primary tumor evaluation and CT chest and bone scintigraphy (BS) for metastatic detection. 18Fluorodeoxyglucose (18FDG) positron emission tomography (PET)/CT has become more common for disease evaluation, yet there is no consensus for its use in this population.

Temporal and spatial mouse brain expression of cereblon, an ionic channel regulator involved in human intelligence.

A mild form of autosomal recessive, nonsyndromal intellectual disability (ARNSID) in humans is caused by a homozygous nonsense mutation in the cereblon gene (mutCRBN). Rodent crbn protein binds to the intracellular C-terminus of the large conductance Ca(2+)-activated K(+)channel (BK(Ca)). An mRNA variant (human SITE 2 INSERT or mouse strex) of the BK(Ca) gene (KCNMA1) that is normally expressed during embryonic development is aberrantly expressed in mutCRBN human lymphoblastoid cell lines (LCLs) as compared to wild-type (wt) LCLs.

Preliminary development of a diabetic foot ulcer database from a wound electronic medical record: a tool to decrease limb amputations.

Our objective was to create a practical standardized database of clinically relevant variables in the care of patients with diabetes and foot ulcers. Numerical clinical variables such as age, baseline laboratory values, and wound area were extracted from the wound electronic medical record (WEMR). A coding system was developed to translate narrative data, culture, and pathology reports into discrete, quantifiable variables.
