Radiation overexposure is common in chest X-ray (CXRs) of pediatric patients. However, overexposure may reveal incidental findings that can help to guide patient management or warrant quality improvement. To assess the prevalence of overexposure in CXRs in pediatric intensive care unit (PICU); and identify the incidental findings within overexposed areas, we conducted a retrospective cohort study of children who were admitted to PICU. Two independent evaluators reviewed patient's charts and digital CXRs according to the American College of Radiology standards; to evaluate overexposure of the anatomical parameters and incidental findings. A total of 400 CXRs of 85 patients were reviewed. The mean number of CXRs per patient was 4.7. Almost all (99.75%) CXRs met the criteria for overexposure, with the most common being upper abdomen (99.2%), upper limbs (97%) and neck (95.7%). In addition, 43% of these X-rays were cropped by the radiology technician to appear within the requested perimeter. There was a significant association between field cropping and overexposure (t-test: t = 9.8, P

Hemophagocytic lymphohistiocytosis (HLH) is a rare and fatal entity with an incidence rate of 1.2 cases per million people per year. HLH is explained as a highly destructive inflammatory consequence of rampant hypercytokinemia due to excessive lymphocyte-mediated activation of macrophages and histiocytes. Primary HLH is a product of genetic dysfunction and could be familial (five subtypes), syndromic immunodeficiency, or as a consequence of mutations predisposing a person to Epstein Barr Virus (EBV) infection. With secondary HLH, there is an identifiable cause provoking the inflammatory reaction, whether it is an infection, an autoimmune disease, or malignancy (particularly hematological). As a result of widespread cytokine deposition, systemic manifestations are seen with a variety of manifestations that can vary between cases. This is a case of a patient who initially presented to the emergency department with fever, altered mentation, and gastroenteritis. Initial investigations showed non-anion gap metabolic acidosis, high white cell count, and deteriorating renal function. Further laboratory tests, bone marrow biopsies, and neurological imaging were conducted throughout the course of admission as the patient further deteriorated systemically. However, it's important to note the abundant neurological manifestations with a worsening level of consciousness and seizures, some of which were categorized as status epilepticus.

Background: Anatomical overexposure is common in CXRs of pediatric patients. However, overexposure may reveal incidental findings that can help to guide patient management or warrant quality improvement. Objective: To assess the prevalence of overexposure in chest X-ray (CXRs) in pediatric intensive care unit (PICU); and identify the incidental findings within overexposed areas. Materials and methods: Retrospective cohort study of children admitted to PICU. Two independent evaluators reviewed patient’s charts and digital CXRs according to the American College of Radiology standards; to evaluate overexposure of the anatomical parameters and incidental findings. Results: A total of 400 CXRs of 85 patients were reviewed. The mean number of CXRs per patient was 4.7. Almost all (99.75%) CXRs met the criteria for overexposure, with the most common being upper abdomen (99.2%), upper limbs (97%) and neck (95.7%).
