Purpose: Placement of a central venous catheter (CVC) is the most commonly performed pediatric procedure. This study aims to develop simple formulas to calculate intravascular length of CVCs prior to insertion to minimize reliance on fluoroscopic and radiographic imaging, which may not be uniformly available.
Methods: We performed a single-institution, retrospective review of 115 pediatric patients who received both CVC placement and computed tomography (CT) imaging of the chest within 3 months of the procedure.
Article Synopsis
- Inflammatory myofibroblastic tumor (IMT) is a type of intermediate malignancy, and this study involves a large cohort of patients (182) under the age of 39 to better understand the disease.
- The findings showed that the median age of patients is 11 years, with common symptoms including pain and respiratory issues, and a notable 53% of tumors displayed ALK overexpression.
- Surgery was frequently performed (91%), leading to a high 5-year survival rate of 95%, but certain factors like tumor size and respiratory symptoms were linked to recurrence risk, indicating that aggressive surgical approaches may not always be necessary.*
Purpose: To describe the oncologic and surgical management of bilateral Wilms tumor or Wilms tumor arising in a horseshoe kidney with intravenous tumor thrombus to help pediatric surgeons negotiate this rare and difficult anatomic circumstance.
Methods: A single-institution, retrospective medical record review identified 4 cases of bilateral WT and one case of WT arising in a horseshoe kidney with intravenous tumor thrombus between 2009 and 2021. The presentation, imaging, chemotherapy regimen, intraoperative approach, and surgical and oncologic outcomes were reviewed for each of these patients.
Background: Optimal management of neutropenic appendicitis (NA) in children undergoing cancer therapy remains undefined. Management strategies include upfront appendectomy or initial nonoperative management. We aimed to characterize the effect of management strategy on complications and length of stay (LOS) and describe implications for chemotherapy delay or alteration.
