Post-hepatectomy liver insufficiency (PHLI) is a significant cause of morbidity and mortality after liver resection. Quantitative imaging analysis using CT scans measures variations in pixel intensity related to perfusion. A preliminary study demonstrated a correlation between quantitative imaging features of the future liver remnant (FLR) parenchyma from preoperative CT scans and PHLI. The objective of this study was to explore the potential application of quantitative imaging analysis in PHLI in an expanded, multi-institutional cohort. ⋯ Quantitative imaging features are independently associated with PHLI and are a promising preoperative risk stratification tool.

Exophytic cerebral hemispheric low grade glioma: An unusual growth pattern of a common central nervous system tumour.
Exophytic growth (EG), wherein the tumor mass grows beyond the neuraxial boundary formed by pia mater, remains a rare pattern of glioma growth. It has been described in gliomas at several locations like the brainstem, cerebellum, suprasellar area, spinal cord, and insula. However, EG in hemispheric grade 2 astrocytomas, particularly affecting the convexity subarachnoid space, as against the more spacious basal subarachnoid space, is exceedingly rare. To the best of our knowledge, there is only 1 such case reported in the English literature. Due to the extreme rarity, little is known about these tumors, particularly the mechanisms underlying the EG and their possible clinical implications. ⋯ Although extremely rare, cerebral hemispheric grade 2 astrocytomas may have an EG pattern. The exact mechanisms underlying this are not clearly known. More such cases need to be reported so that we can decipher the true nature of these tumors.

Systemic Administration of Carbon Monoxide-Releasing Molecule-3 Protects the Skeletal Muscle in Porcine Model of Compartment Syndrome.
Acute limb compartment syndrome, a complication of musculoskeletal trauma, results in muscle necrosis and cell death. Carbon monoxide, liberated from the carbon monoxide-releasing molecule-3, has been shown protective in a rat model of compartment syndrome. The purpose of this study was to test the effect of carbon monoxide-releasing molecule-3 in a preclinical large animal model of compartment syndrome, with the ultimate goal of developing a pharmacologic adjunct treatment for compartment syndrome. ⋯ Administration of carbon monoxide-releasing molecule-3 at fasciotomy offered protection against compartment syndrome-induced microvascular perfusion deficit, tissue injury, and systemic leukocyte activation. The data suggest the potential therapeutic application of carbon monoxide-releasing molecule-3 to patients at risk of developing compartment syndrome.
