Propofol Infusion Syndrome
Though rare, propofol infusion syndrome (PRIS) is a cause of acute kidney injury in the appropriate ICU setting. As we all know, propofol is an intravenous sedative currently favored in the ICU due to relatively short half-life and…
Pseudohyponatremia
Hyponatremia can be broadly divided into two fundamental categories: “true hyponatremia” (in which the serum sodium concentration is truly less than normal), or “pseudohyponatremia,” in which the serum sodium concentration is actually normal but erroneously reported as low…
Winter’s formula and even simpler
Let’s talk about rapid A.B.G. analysis. Just to clarify, I’m talking about arterial blood gases, not the religious rap group “Adopted By Grace” I just discovered existing by googling the phrase “ABG”. I tend to use Winter’s Formula…
Kim-1 Renastick
This month’s Kidney International features an interesting report by Vaidya et al which reports on the development of a potentially useful dipstick test able to detect urinary Kim-1, a promising new biomarker for acute kidney injury. As we…
AAMI…What You Wanna Do?
For a while, maybe longer if I do…. No, I’m not talking about the one-hit wonder song “Amy” by Pure Prairie League…I’m talking about AAMI (the Association for the Advancement of Medical Instrumentation), the organization which regulates water…
Why doesn’t this catheter work?
Dialysis catheters: the bane of the renal fellow’s existence. I’m sure there are some of you who actually like putting in catheters and are quite good at it, and while I will admit that an efficient line placement…
Serum Free Light Chain Assay
The dilemma: there are a subset of patients with some type of paraproteinemia–e.g., light chain deposition disease or amyloidosis, for instance–which are NEGATIVE by SPEP & UPEP. When there is renal involvement, the diagnosis can potentially be made…
Speaking of Ethylene Glycol Poisoning…
If you’ve never heard the biochemical sleuthwork involved in the legal case of Patricia Stallings, it’s definitely worth reading about: a good summary of the case can be found here. Briefly, it involves a St. Louis-area woman who,…
Wood’s Lamp Trick for Diagnosing Ethylene Glycol Toxicity
One of the more common (and potentially successful) suicide attempts is to drink a bunch of antifreeze, which contains ethylene glycol. As we all know, this is typically diagnosed by characteristic lab abnormalities: patients present initially with an…
Macroglossia
As you may recall, macroglossia (an enlarged tongue) is one of the many manifestations of amyloidosis, the systemic disorder in which a particular protein is deposited as Congo-red positive aggregations. You may also recall that amyloidosis can be…
