Let's start with an initial problem representation:
A 73 y/o M w/ a pmh of DM2, depression, hypoTh, BPH presents w/ a few days of nocturia & LE pain & brought in bc he was found lying on the floor of his bathroom disoriented after experiencing dizziness, blurry vision & falling
Was this fall a syncope or seizure?
Sounds like reflex vs orthostatic syncope but keeping all buckets open.
Foresee an EEG & MRI to check for seizures...
A hx of any cardiac disease will be helpful. also thinking about syncope mimics - stroke, seizure, hypoglycemia
Also, check a CK for possible Rhabdo and a lactic acid (makes seizure more likely)
is this disorientation post-ictal?

It usually presents at an average age of 6.5-17 depending on the study. This one from JAMA found that among 3,741 patients with rheumatic fever entering Bellevue Hospital from 1911 to 1919, Lambert found 91 over the age of 60.
What about an atrial myxoma? What type of murmur would one have?
The murmur of a left & right atrial myxoma can have similar auscultatory findings as mitral and tricuspid stenosis, respectively.
It is typically a mid-diastolic, crescendo diastolic murmur.
The diastolic murmur occurs as the atrial myxoma causes atrioventricular valve obstruction.
Long-term Metformin Use and Vitamin B12 Deficiency
Long-term use of metformin in DPPOS was associated with biochemical B12 deficiency and anemia. Routine testing of vitamin B12 levels in metformin-treated patients should be considered. ncbi.nlm.nih.gov/pmc/articles/P…
His EMG showed neuropathy likely from his B12 def and his fall was considered multifactorial from the low sodium UTI, paresthesias causing LE pain and multiple medication interactions including a new herbal supplement.
Remember to check a list in the elderly pt w/ falls
Hematogenous dissemination then can occur typically 4 to 10 weeks later, giving rise to secondary syphilis. <40% of pts w/ syphilis have primary syphilis diagnosed. These “Secondary” lesions last for several weeks before spontaneously resolving. Coined “early, latent infection”
What does late infection mean? When syphilitic lesions recur after 1 year from the initial eruption, or seropositivity is detected more than 1 year after the initial eruption, it is termed late latent syphilis.
Some optics neuritis pearls in a short #Medtweetorial 🧵…. We all know that optic neuritis is frequently associated with multiple sclerosis (MS). But optic nerve inflammation can exist from autoimmunity, infection, granulomatous disease, paraneoplastic disorders, & demyelination
Classical ON from MS is unilateral, moderate, painful color vision loss with an afferent pupillary defect & normal fundus examination.
In those with ON, 95% of patients showed unilateral vision loss & 92% had associated retroorbital pain that frequently worsened w/ eye movement.
If you have not listened to the @CuriousClinPod most recent podcast (Episode 10: Why does metronidazole treat both bacterial and parasitic infections?) then I suggest you tune in.
I'll summarize their show notes here in short #medtweetorial
First a question:
Was metronidazole first used as an antibiotic or as an antiparasitic?
If you guessed antiparasitic, then you would be correct!
It was developed in the 1950s to treat the parasite trichomonas & then was used in the 1960s to treat other parasitic infections, like giardia and amoebiasis.
A 31-year-old M born and raised in Brazil w/ no PMH presented with a 3 mon history of worsening DOE, orthopnea, 7kg weight loss, abdominal distention, dry cough, and syncope
An interesting fact from @3owllearning : Depending on the clinical problems, the studies of disease probability for differential diagnosis often show 10 - 25% of cases are unexplained, even after careful examination and testing.
