MRI changes in Haemodialysis and Manganism
Well what do you know? Seems there might be some association between haemodialysis patients getting high serum manganese levels and imaging changes in the brain on T1-weighted MRI A Preliminary Study Revealing a New Association in Patients Undergoing Maintenance Hemodialysis: Manganism Symptoms and T1 Hyperintense Changes in the Basal Ganglia | American Journal of Neuroradiology
MRI Brain changes in Hyperammonaemic Encephalopathy
Fascinating paper by U-King-Im et al about the changes in the brain observed in hyperammonaemic encephalopathy during MRI. Acute Hyperammonemic Encephalopathy in Adults: Imaging Findings | American Journal of Neuroradiology
Medical Unit Conversion Calculator
Quickly convert between commonly used medical units across biochemistry, gases, and physiology.
Simple Molecule Size Searcher
This is just to find out what molecules are the right size for what sort of extracorporeal removal, if at all. These weights are (mostly) just an approximation, especially as they get into the tens of thousands. Have a go. I found it interesting, hopefully you might, too. NB: Haemodialysis generally removes molecules <20kDa in … Read more
Blood Gases
I’m going to focus on Arterial blood gases here. Venous gases are close enough in well people, but beware in critical illness there is divergence between arterial and venous samples, particulary in CO2, lactate and pH. Method FiO₂ Calculator 713 x 0.21 = 150 mm Hg Differential Diagnosis HAGMA (CATMUDPILES or LTKR) NAGMA (CAGE, ABCD, … Read more
