 #Cryptococcal Infection in #Hematologic #Malignancies and Hematopoietic Stem Cell Transplantation

Here we review crypto with attention to its background, epi, risk factors, presentations, diagnosis, treatment, & prevention in hematologic malignancies

 At baseline, even prior to the start of immunosuppression, newly diagnosed patients with heme malignancies have cellular & humoral immune deficits with functional and absolute defects in granulocyte and lymphocyte function
that place patients at increased risk for infections

Growing up in Tucson and going to med school @UAZMedTucson, I thought I knew a lot about #coccidioidomycosis. Definitely not!

Here we discuss history, epidemiology, ecology, some cool facts about #Cocci, and reasons why #fluconazole may not be the best drug for Cocci. 2/
 In 1892 in Argentina, Alejandro Posadas wrote the first report of a pt w/ disseminated cutaneous cocci

Shortly after, a laborer in San Joaquin valley also had skin lesions

Skin biopsies of both pts revealed protozoa-like orgs, similar to Coccidia

Let's start off 2020 with some #Bacteremia myth💥!!

Some questions answered here:
Do fevers predict bacteremia?

Can you predict when someone will have an ESBL bacteremia?

I learned a lot preparing this review, I hope you do too

#MedTwitter #IDTwitter #MedEd 2/
 Is it normal for people to be bacteremic on a daily basis?

I bet you are wondering, what's all the fuss with #candidemia? Why do we care? How to diagnose? How to treat?

Get ready for a thanksgiving treat!

In the US, invasive candidiasis is the most common fungal infection in hospitalized patients (4th most common infection overall)

1. C. diff
2. Staph aureus
3. E. Coli
4. Candida

 Hi hi hi. We see lots of red flags on a daily basis when we review labs.

One thing we see commonly is #lymphopenia. Should we care? When can we dismiss it and when should we work it up?

Let’s find out.

#MedEd #MedTwitter #IDTwitter #Tweetorial #oncology 2/
 - Lymphopenia assc w/ ⬆️risk of sepsis
- More common in elderly and w/ co-morbidities
- lymphs account for 20-40% of WBC, may go unnoticed when WBC checked w/o diff
- Primary- recurrent infxns in kids, CVID in adults
- Secondary-⬇️production; ⬆️destruction; hiding in tissue

Have you ever wondered about the testing characteristics of the #Histoplasma antigen? We order them all the time, but how good are they? Come, let's explore together!
#Histoplasmosis #IDTwitter #MedEd 2/
 First, let's discuss distribution and some background information. We shouldn't say that Histo is an endemic mycosis given its worldwide distribution. Factors that influence this include #ClimateChange and #Deforestation.
