Irradiation-induced sarcomas are well-known potential late sequelae of radiation therapy. These tumors are very aggressive and often elude early detection and timely intervention, rapidly leading to early demise of afflicted patients. Long-term patient follow-up and a high index of suspicion are crucial for timely intervention. In this report, we present a case of irradiation-induced osteosarcoma involving the mandible. Diagnostic and therapeutic considerations are subsequently discussed.

Emergency Department Visits Following Supracondylar Humerus Fractures.
J Pediatr Orthop

Department of Orthopaedics and Rehabilitation, Yale School of Medicine, New Haven, CT.
Introduction: Pediatric supracondylar humerus fractures are common and the most frequent pediatric fracture to require surgical intervention. After initial management, emergency department (ED) visits subsequent to this injury/surgery are not well characterized, but are of clinical interest.
Methods: Pediatric patients (age >1 y old and <13 y old) with supracondylar humerus fractures were identified from the 2010 to 2021 PearlDiver M157 administrative database.

Mycotoxin exposure from contaminated food is a significant global health issue, particularly among vulnerable children. Given limited data on mycotoxin exposure among Namibian children, this study investigated mycotoxin types and levels in foods, evaluated dietary mycotoxin exposure from processed cereal foods in children under age five from rural households in Oshana region, Namibia. Mycotoxins in cereal-based food samples (n = 162) (mahangu flour (n = 35), sorghum flour (n = 13), mahangu thin/thick porridge (n = 54), oshikundu (n = 56), and omungome (n = 4)) were determined by liquid chromatography-tandem mass spectrometry.
