Time for some #SpacedRepetition: @CPSolvers @DxRxEdu @rabihmgeha
Chat recap of the #ClinicalPearls #VirtualMorningReport

August 11th Episode 114: clinicalproblemsolving.com/morning-report…
W / @Anu08877649 Joshua Morris & @Rafameed

Let’s start with an initial problem representation:

A 55 y/o M w/ no known PMH except a 30 pack-year history of tobacco abuse presents with recurrent syncope (lightheaded prodrome) over last 2 mon along w/ R shoulder pain, 15 lb weight loss for 3 months, and an occasional cough
An initial evaluation of syncope should involve ruling out mimickers like Sz or TIA

The fact that he was lying down during the episode is concerning for cardiogenic cause like an arrhythmia

Also, an autonomic given the lightheadedness while lying in bed

Is the shoulder pain referred pain?

I wonder about a possible SVC syndrome or mass around carotid causing unilateral carotid compression

never forget cardiac shunts and Eisenmenger syndrome even in adults Image
What about pulm HTN as cause of syncope w/ liver congestion⏩shoulder pain?

Is referred shoulder pain td to palpation? Seems to point to tissue. Maybe an abscess or mets to scapula

Could also think of Subclavian Steal syndrome ⏩syncope

Any B symptoms?? other than weight loss
He did have recent travel to Vietnam:

Seems like the timing of all symptoms started after returning from Vietnam, but if they have a mechanical cause of syncope like malignancy you’d expect that to have been developing for longer and unrelated to the travel. Signal vs noise?
Shoulder pain, weightloss, syncope - worried about lung cancer or TB

His vitals show no fever, a normal BP but he has bradycardia at 51 bpm

bradycardia > infiltrative dz > heart block

His physical exam shows R scapula td w/ normal lung and heart sounds, no lymphadenopathy
His labs show a nml WBC of 10, Hgb 13, Plt 400

Chemistry panel WNL (nml calcium)

Nml Alk phos (was interesting in seeing if this was elevated 2/2 bony mets)

Nml albumin:

How much does Albumin correlate with weight loss?
Serum albumin levels may not correlate with weight status in severe anorexia nervosa

pubmed.ncbi.nlm.nih.gov/19548148/

What about pre-albumin?

Serum pre-albumin is not an accurate surrogate for weight loss during hospitalisation.

medpharm.tandfonline.com/doi/full/10.10…
Here’s another:
pubmed.ncbi.nlm.nih.gov/25912205/ Albumin is a good negative acute phase reactant, but not great for nutritional status

The "markers" failed to identify subjects with severe protein-calorie malnutrition until extreme starvation.
Chest xray is interesting and likely the pivot point showing a LUL mass

Weird that lung mass is in L upper lobe, but having R shoulder pain

Hmmm, we need more imaging. How about a CT scan
CT chest showing a large left lung mass, lymphadenopathy (none palpable) along with a lytic lesion in the right scapula

Man that CT is better than our exam but that is not unusual

Maybe this mass is compressing the vagus nerve
Also note that recurrent laryngeal nerve is more medial than vagus (if we remember correctly so if it's impinging RLN then likely also compressing vagal nerve Image
Biopsy of scapula showed squamous cell carcinoma

PET showed a LUL hypermetabolic lesion w/ vagus nerve impingement, mediastinal mass w/ RLN impingement ⏩ bradycardia & syncope

Recurrent Syncope as Initial Symptom in Apical Intrathoracic Tumor

Some cool #Syphilis Pearls from an article that @k_vaishnani shared ncbi.nlm.nih.gov/pmc/articles/P… Primary syphilis first manifests into a painless chancre at the site of inoculation 1 to 6 weeks later…
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 Image
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.

curiousclinicians.com/2020/09/30/why…

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.

When you order a serum alcohol level, what does the lab measure? An answer and a quick #Medtweetorial on false elevations in #ETOH
If you guessed NADH, you would be correct.
Most lab assays for serum alcohol utilize a reagent containing alcohol dehydrogenase & NAD+

This is used to convert all present ethanol to acetaldehyde

Thereby reducing present NAD+ to NADH.

A Teal pain in the neck:

Follow along for a short #medtweetorial on #CervicalArteryDissection

or see the full handout here emboardbombs.com/s/Cervical-Art…

from @EMBoardBombs @blakebriggsMD @IltifatMD
This review will focus on spontaneous dissections, not traumatic, as well as the pathophys, risk factors, presentation, diagnosis, and management.

Cervical artery dissections are a common cause of stroke in young(<50 years )w/ some reports of up to 20% being from dissections
Much like aortic dissections, there is some loss of structure along the wall of either the internal carotid artery or vertebral artery

This allows blood to collect within the intima.

In patients <50 years old, cervical artery dissections account for 20% of ischemic strokes.

Time for some #SpacedRepetition from @CPSolvers @DxRxEdu @rabihmgeha

Some chat recap #ClinicalPearls and bonus pearls from #VirtualMorningReport on Friday Sept 25th clinicalproblemsolving.com/morning-report…

Case by the brilliant @Rafameed Image
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

Base rate of disease for an ID case with @k_vaishnani and @Rafameed is very high
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.
