A couple weeks ago I was caring for a patient on the heme-onc service that developed progressive L-sided neck/face swelling over 3-4 hours! He ended up having suppurative parotitis, a diagnosis I have not seen very much in practice. Here are some takeaways #MedTwitter
Risk fxrs for suppurative parotitis include poor PO intake, poor dentition/recent dental work, oropharyngeal malignancies, & intubation (all via impaired stimulation/drainage of salivary ducts). The most common offending bugs are Staph Aureus & anaerobes (pubmed.ncbi.nlm.nih.gov/12544218/)
Both US and CT can be used as imaging modalities in the workup of suppurative parotitis. US can identify a potential obstructing stone more easily while CT is more sensitive for ruling out an abscess. Another diagnostic hint is elevated amylase w/ normal lipase

Let's talk about cytopenias in cirrhosis. Many patients with cirrhosis will have at least one cytopenia (sometimes pancytopenia) attributable to their liver disease, let's talk about some of the mechanisms! #medtwitter #hemetwitter
First up, thrombocytopenia! The potential mechanisms are laid out in the image below (aasldpubs.onlinelibrary.wiley.com/doi/full/10.10…):
- decreased thrombopoietin production
- sequestration
- alcohol/viral causes suppressing marrow
- peripheral destruction
Next up, anemia! The ddx should include the causes we think of in all anemia patients (nutritional, GI losses, hemolysis etc...) but what are some liver-specific etiologies? Spur-cell anemia (ashpublications.org/blood/article/…) typically only reverses w/ transplant

An awesome discussion from the @CPSolvers and Drs. Gandhi and Bressman! Here are some thoughts about the pivot point of the case... #SpoilerAlert
Drs. Gotlib and Reiter put an an excellent review discussing myeloid neoplasms with hypereosinophilia (ashpublications.org/blood/article-…), these are some of the salient points for all IM folks to take away
The first is knowing that the terms hypereosinophilia and hypereosinophilic syndrome (HES) carry specific meaning! HES meets the definition for hypereosinophilia + there is organ damage 2/2 hypereosinophilia

Saw a patient in clinic w/ (likely) refractory ITP and luckily there was an excellent @BloodJournal article by Miltiadous and colleagues published earlier this month! I want to highlight some of the main learning points I took away #medtwitter #hemetwitter ashpublications.org/blood/article/…
# 1: Make sure that the patient truly has primary, refractory ITP! If a patient is not responding as expected with primary ITP-directed therapies, it bears consideration to do a more extensive workup looking for alternative diagnoses ImageImage
#2: If a patient is not responding as expected to treatment for ITP, have a low threshold to pursue a bone marrow biopsy. A number of bone marrow failure states can present with isolated thrombocytopenia Image

Check out my @hdx case from today: a 62-yo man with chest pain! Thanks to @AnandJag1 for the edits. Below you will find some teaching points about this case #SpoilerAlert #Medtwitter
As part of our patient's PMH, he reported facial nerve palsy. Here is a slide with some teaching points about Bell's Palsy including the differential diagnosis to consider (Eviston et al, 2015) Image
Our patient gets imaging in the case that shows cavitary lung lesions. A brief ddx for cavitary lung lesions is below (Gadkowski et al, 2008) Image

Hi #MedTwitter, let's talk about the workup of polycythemia and making a diagnosis of polycythemia vera (PV) vs. secondary polycythemia! #mpnsm #tweetorial @MedTweetorials
Based on the WHO guidelines, the following values constitute polycythemia:
In men: Hgb >16.5g/dL or Hct > 49%
In women: Hgb > 16 or Hct > 48%

Polycythemia should be confirmed by a subsequent CBC. Below is an image of the ddx of polycythemia (Keohane et al 2013) Image
Our patient's polycythemia has been confirmed! What to do next? Make sure to ask questions related to hyperviscosity (eg chest pain, dyspnea, headache, vision changes, confusion), thrombosis/bleeding hx, and PV-related symptoms (pruritus after baths, erythromelalgia, B-symptoms)
