Heard an excellent presentation at our Renal Grand Rounds today by Dr. Charles O’Neill of Emory University, regarding the process of pathologic calcification in CKD/ESRD patients. One of the points I took away from this talk is that…
TB is classically thought of as a pulmonary disease–and in general, this is true, as pulmonary TB is by far the most common (and often very severe) manifestation of infection by Mycobacterium tuberculosis. However, the most common NON-pulmonary…
One of the hot topics in Nephrology over the past few years has been the epidemiologic and histopathologic studies suggesting oral sodium phosphate colonoscopy preparations as a cause of acute phosphate nephropathy. As evidence continued to mount, the…
Following on the heels of studies showing a potentially beneficial effect for vasopressin receptor antagonists and rapamycin in the treatment of renal cystic disorders, an article in this month’s JASN by Gattone et al suggests another class of…
One of the diagnostic dilemmas which frequently comes up in the outpatient evaluation of hypercalcemia (and also, I’m told, on boards-type exams) is how to differentiate familial hypocalciuric hypercalcemia versus primary hyperparathroidism–both of which are common causes of…
Following up on the discussion of milk-alkali syndrome, a similar syndrome (hypercalcemia, metabolic alkalosis, and acute renal failure) may also occur due to betel nut chewing. Betel nut chewing is a common habit and cultural practice amongst Indian…
Heard about a case of milk-alkali syndrome at Renal Grand Rounds yesterday. This is an interesting condition whose pathophysiologic mechanism really tests your knowledge of calcium and acid-base homeostasis. I won’t attempt to chart the pathway but a…
Lithium, a very effective medication in the treatment of bipolar disorder, has a variety of well-documented renal side effects, including interstitial nephritis and nephrogenic diabetes insipidus. A less well-recognized complication is an increased prevalence of hyperparathyroidism in chronic…
One logical way to classify the different etiologies of hypocalcemia is to break them down into LOW PTH STATES and HIGH PTH STATES. Today I’ll review the HYPOCALCEMIA WITH LOW PH STATES, or in other words, the causes…
Calcium is a critical ion for a number of cellular signaling events. As such, it is not surprising that hypocalcemia leads to a wide variety of signs and symptoms. The dominant presentation of hypocalcemia is usually neurologic in…
