Article Synopsis
- Smokeless powders (SLPs) consist of thermolabile and non-thermolabile compounds, and their analysis using GC-MS (Gas Chromatography-Mass Spectrometry) can be significantly influenced by the conditions during injection, but no systematic studies had been previously conducted.
- A recent study examined how the type of injector liner and the inlet temperature affect the chemical profiles of SLPs, revealing that both factors are crucial for obtaining reliable results, with the liner type having a notable impact.
- Interestingly, while higher temperatures led to the degradation of some thermolabile compounds like nitroglycerin, these extreme conditions actually resulted in more consistent measurements, suggesting that contrary to prior beliefs, harsher conditions might be more beneficial for profiling.
Myeloid sarcomas (MS) are solid manifestations of acute myeloid leukemia (AML) and are commonly present in children. These tumors can arise in many tissues including bone, soft tissue, or skin, and are commonly seen in the orbit. As practically all MS will, if left untreated, eventually present as AML, early diagnosis and initiation of treatment are imperative.

If more than one magnet is ingested, the attraction between loops of the bowel can bring adjacent loops closer together, leading to perforation, obstruction, or fistulization. Pediatric magnet ingestion patients often require endoscopic or surgical intervention to retrieve the objects and repair the damage created by the magnets.
View Article and Find Full Text PDFOptic pathway gliomas (OPGs) are a classic pathology seen in patients with neurofibromatosis I (NF-1); however, they are frequently seen as sporadic masses in patients with mutations activating the mitogen-activated protein kinase (MAPK) pathway. These sporadic tumors present rapidly with vision deficits, compared to those in neurofibromatosis I, which may be found incidentally. They can involve multiple aspects of the optic pathway and have classic imaging findings that make definitive diagnosis possible with magnetic resonance imaging.
