As the operative management of acute, chest wall, skeletal injury escalates throughout the world, it has become commonplace for patients with posttraumatic conditions to present with clinical reconstructive challenges as well. In addition, it is becoming clear that rib nonunions are not rare, likely more than 5% of rib fractures. No subspecialty is better equipped to address such painful conditions than orthopaedic surgery.

Children, adolescents, and young adults with low-risk, relapsed cHL may benefit from replacing high-dose chemotherapy and autologous stem cell transplant with less intensive involved-site radiotherapy (ISRT).
Objective: To evaluate a risk-stratified, response-adapted, transplant-free approach for treatment of children, adolescents, and young adults with low-risk relapsed cHL with nivolumab plus brentuximab vedotin (BV) followed by BV plus bendamustine for patients with suboptimal response and ISRT (30.
Treatment of acute lymphoblastic leukemia (ALL) is associated with neurocognitive deficits in young children. While computerized measures have been utilized in pediatric oncology research, they exclude patients below the age of 4 years. Patients enrolled on "Treatment of Newly Diagnosed Acute Lymphoblastic Leukemia in Children and Adolescents" were offered participation in an optional neurocognitive study.

The severity of this impairment is influenced by host, disease, and treatment factors, and the impairment affects patients before, during, and following cancer treatment. The National Cancer Institute (NCI) Symptom Management and Health-Related Quality of Life Steering Committee (SxQoL SC) convened a clinical trial planning meeting to review the state of the science on cancer-related cognitive impairment and develop phase II/III intervention trials aimed at improving cognitive function in cancer survivors with non-central nervous system disease and longitudinal studies to understand the trajectory of cognitive impairment and contributing factors.

To identify the underlying genetic contributors, we conducted a genome-wide association study (GWAS) and a transcriptome-wide association study (TWAS) in 260 patients of European-descent from the DFCI 05-001 ALL trial, with validation in 101 patients of European-descent from the DFCI 11-001 ALL trial. We identified a significant association between rs844882 on chromosome 20 and bone toxicities in the DFCI 05-001 trial (p = 1.

Supplemental Nutrition Assistance Program (SNAP) benefits improve food insecurity and child health outcomes, and could be used to mitigate disparities. We conducted a secondary analysis of parent-reported data collected in a frontline pediatric leukemia trial (NCT03020030) to assess SNAP eligibility (proxied by other means-tested program participation) and participation.

Early detection of this damage, including its identification and quantification, is critical to preventing the disease's progression in the brain. Tau, glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL), as brain protein biomarkers, have the potential to improve diagnostic accuracy, disease monitoring, prognostic assessment, and treatment efficacy.
View Article and Find Full Text PDFThe inferior glenoid and scapular neck are common locations for scapular fractures. Operative exposures for reduction and fixation can be challenging, and frequently, the proximal fracture planes are not conducive to optimal fixation with a plate alone. The purpose of this article was to describe a new technique for enhancing fixation in specific inferior glenoid fractures using a single cortical lag screw.

Experimental Design: Overall, 296 patients (age 2-21 years) in the overall population were randomized to and received BV + chemotherapy; the pharmacokinetic subpopulation comprised 24 patients (age <13 years). Age- and/or BW-based (pharmacokinetic surrogates) subgroup analyses of efficacy and safety were conducted for the overall population.
Background: Ankle fractures are a common injury treated by orthopaedic surgeons. Unstable, displaced ankle fractures are often fixed with open reduction internal fixation (ORIF) using different implant constructs at various cost. No study to date has looked at transparency in ankle implant costs to surgeon behavior.

However, no head-to-head comparisons with standard salvage chemotherapy have been performed. This study presents a propensity score-matched analysis encompassing individual patient data from 10 clinical trials to evaluate the impact of BV in transplant-eligible patients with R/R cHL.

Setting: Single, academic, Level 1 trauma center.
There is a growing understanding and identification of costal cartilage injuries, however, diagnosis of these injuries remains difficult. We present a novel radiodensity based coloring technique, termed the True-Blue technique, to manipulate 3D CT imaging and more accurately diagnose costochondral injuries.

However, many cancer surviving children and adults suffer from aberrant chemotherapy neurotoxic effects on learning, memory, attention, executive functioning, and processing speed. This chemotherapy-induced cognitive impairment (CICI) is referred to as "chemobrain" or "chemofog".

While most rib fractures ultimately go on to achieve bony union, a subset of patients may go on to develop non-union. Management of these nonunited rib fractures can be challenging and variability in management exists.

He underwent surgical reconstruction of the chest and was followed for 2 years. Surgical exposure to the heart was necessary during open reduction of the flail segment, followed by costochondral joint fixation with plates and screws.

Although operative indications are well-defined, certain fracture patterns and patient cohorts are at greater risk of failure. When operative intervention is necessary, internal fixation through an anterolateral approach is a safe and sensible alternative.

Background: Rarely, traumatic sternum fractures may result in nonunion, which can have drastic, negative implications. Literature on traumatic sternal nonunion reconstruction outcomes is limited to case reports. We present the surgical principles and report clinical outcomes for seven patients following surgical reconstruction of a traumatic sternal body nonunion.

Materials/methods: Total 143 patients treated for stage IIIB/IVB HL on COG AHOD0831 were included in this study. Six definitions of LMA were investigated: (i) mediastinal mass ratio on CXR (MR ) > 1/3; (ii) mediastinal mass ratio on CT (MR ) > 1/3; (iii) mediastinal mass volume on CT (MV ) > 200 mL; (iv) normalized mediastinal mass volume (MV /thoracic diameter [TD]) > 1 mL/mm; (v) mediastinal mass diameter on CT (MD ) > 10 cm; and (vi) normalized mediastinal mass diameter (MD /TD) > 1/3.
