Infectious Disease

First tweetorial of the new academic year. Coagulase negative Staphylococci (CoNS) bacteremia is a frequent ID consult. So how do the pros handle the CoNS? Here is a quick generalized approach I use by creating a mnemonic out of CoNS. 1/10

Great! Three quarters find inquiring about fever patterns still useful. We will review some of the most important fever patterns.

Why do we feel cold (i.e., experience "chills") when we have a fever? Shouldn't we feel hot?

And what are rigors?

Answers to these questions will help us better understand when we should obtain blood cultures.

When do you think is the best time to draw them?

#MayoIDQ Case by Dr. @N_CastilloMD

68F. Aortic stenosis, COPD, RA.
CC: chest pain / dyspnea
CXR: CHF. TEE: AV mass / perivalvular abscess
Routine blood cultures (-)

You order serologies of culture-negative endocarditis. Which of the following is most compatible with Q fever?

Contaminated blood cultures have been recognized as a troublesome issue for decades. This comes at a big cost, with additional costs associated with this unnecessary treatment were approximately $1,000 per patient.

Welcome to a Tweetorial. This week I learned there’s a such thing as chronic meningitis, so I decided to make a 🧵:

#IDBoardReview 50 M vacationing in Caribbean & had a meal of snapper🐠 last night, now presents with N, V, D, HA, weakness in legs, tingling in legs/mouth, cold objects feel hot, bradycardia. Diagnosis? #medEd #IdMedEd

#idgrandrounds
Case presentation:
1/3 | 18/M CC: "most severe headache"

Late summer in IL. 1 wk ago, +fever, myalgia, leg rash. SSX resolved after 4 d. 3 d later, fever recurred (low grade) but now w/ headache. Day of admission, "worse headache" & delirium. Hospital admission.

#medstudenttwitter A review of syphilis testing
1/ Scenario 1: You are seeing a patient in clinic and obtain syphilis screening of HCM. For screening, a nontreponemaltest (RPR or VDRL) are usually sent first. What is the sensitivity of the RPR testing?

A cool fact: Burkholderia mallei was used by the Germans in World War I to infect livestock being shipped to Allied countries.

Burkholderia pseudomallei was investigated as a possible biological warfare agent by both the US and Soviets but it was never successfully weaponized.

What do we know about Multisystem Inflammatory Syndrome Coronavirus Disease 2019 (MIS-C)?🦠

An attempt will be made to explain the pathophysiology known so far, its similarities with other diseases and the difference in their clinical manifestations. #COVID__19 #COVID19

Finally gathering some thoughts after last week's @CPSolvers VMR into a mini #Tweetorial 🧵

A few of my knowledge gaps & questions that came up:
1) What exactly is Strep. mitis?
2) What makes you susceptible to viridans strep endocarditis?

TICKBORNE INFECTIONS (TBI)

It’s summer (= tick bites 🐞) and we have new faculty, fellows, residents, interns, & students coming from different places.
@grepmeded

This tweetorial is an overview of TBI mainly in the US.

COVID Update July 7: I spent the last 24 hours with 3 scientists, all of whom have seen vaccine data, 2 of whom are former regulators, all of whom have opinion.

Will 🧵 soon if interested.

34M rural northwest India p/w abd distension and fevers for 4wks . Resides in a area endemic for visceral leishmaniasis(VL)

O/E Pallor++, massive splenomegaly . No lymphadenopathy.

Hb 7.2 , WBC 2.5K Plts 25K
HIV (-)

Preferred method for definitive diagnosis of VL ?

Thanks to @Rafameed for a great @CPSolvers VMR case! Which led me to realizing that the 1 page in first Aid that I've read is not enough information about Leishmaniasis - so welcome to a Tweetorial!

When a patient presents with low back pain and saddle anesthesia, we are conditioned to think 🚩🚩🚩!!

And appropriately so.

What emergent causes of back pain do we worry about when saddle anesthesia is reported?

Im on a micro kick this week.. so let's do a #tweetorial! This time let's talk about #fungus 1/n

Time for @MedTweetorials: #OBGYN #tweetorial
