It’s MIST time! with UTI being top on the differential classically in this elderly male who is set up for urinary retention
UTI - often blamed, rarely the cause
meds meds meds: Polypharmacy!
wondering if he’s wobbly wacky and wet?

The rapid decline for any kind of neurodegenerative disease, I think more delirium here
once declines in function become chronic, then we think dementia is more likely, but subacute can be delirium...but characteristically delirium is waxing and waning

Always look for the reversible causes: infection, metabolic, bleeds, endocrine, meds
Thinking metabolic: b12 def, hypo or apathetic hyperthyroidism, hyperCa, wernicke
Lewy Body Dementia can sometimes present more as delirium…and is very sensitive to decompensation from meds

Hyperammonemia can do much of this along with subacute subdural hematomas
Can hyperammonemia cause agitation? The short answer is yes. Sxm& #39;s are nonspecific w/ ataxia, vomiting, focal neuro findings, low-grade fever, drowsiness, lethargy, agitation. https://www.tandfonline.com/doi/pdf/10.1080/24750573.2018.1448133">https://www.tandfonline.com/doi/pdf/1...

Classic hypercalcemia history is polyuria, constipation, &confusion
lethargic & dry mouth: worry a little about anti-cholinergic but more likely dehydration

The postulated mechanism is downregulation of aquaporin-2 water channels, and calcium deposition in the medulla with secondary tubulointerstitial injury, leading to impaired generation of the interstitial osmotic gradient. https://www.amjmed.com/article/S0002-9343(18)31029-5/fulltext">https://www.amjmed.com/article/S...

so cancer and milk alkali will cause similar lab pattern. stopping tums will help differentiate both before embarking on malignancy workup
so now we have the PTH low, PTH-RP low, low VitD
sarcoid vs lymphoma?
Constipation classic for hypercalcemia

Hormonal :
â—‹ PTH: primary, secondary, tertiary hyperparathyroidism
â—‹ PTHRp: renal cell carcinoma or squamous
â—‹ Vit D: increase intake of 25oh , or granuloma producing vit D like substance Lytic processes

o Each tum is 0.5 grams. Usually need 3-4 grams to get milk alkali

The nodes are likely a clue - 1,25 D is borderline high
Tissue is the issue?
@medrants notes that Lymphoma can do this
as well as Granulomatous process such as sarcoid, histo, blasto
bone & lungs lesions suggestive of sarcoid or disseminated histo/blasto

While certain tumors are more known to cause hypercalcemia, it can occur with almost any type of cancer. Hodgkin lymphoma is an infrequent cause of hypercalcemia. Here is another good free case review https://www.hindawi.com/journals/crionm/2019/4129349/">https://www.hindawi.com/journals/...
