What could explain discordant iron studies?
This is an incredibly common question, largely generated by the zeal to use the serum ferritin and failure to appreciate the need for an overnight fast when ordering the TSAT (the ferritin does not require fasting). The most common culprit in this situation is iron containing vitamins. Prenatal vita...
How do you decide whether to use lung POCUS versus CT as the next step when a chest X-ray is equivocal for pneumonia?
Lung ultrasound is a quick, safe, and inexpensive test to perform. If the patient already has a chest X-ray and it is equivocal for pneumonia, I always perform a lung ultrasound. It is useful for evaluating an inflammatory vs. non-inflammatory interstitial process. It is better than an X-ray to dete...
How do you manage residual hyperpigmentation after breast irradiation?
There are definitely options, including modified Kligman formula cream (4% hydroquinone, 0.05% tretinoin, and 0.01% fluocinolone acetonide) for 8 weeks as initial treatment; this - or some iteration of it - is what is typically used for cases of post-inflammatory hyperpigmentation (PIH) or melasma. ...
Do you have to remove gold dental crowns if patch testing reveals a gold allergy?
Not all positive patch tests are relevant. I would only recommend removing the dental crowns if there was some evidence that the gold exposure was contributing to the patient's dermatitis or mucosal inflammation that does not have a better explanation.
Would you consider adding an SGLT2i for a patient with proteinuric kidney disease who is already on maximal dose ACEi/ARB and has a UACR < 300 mg/g?
I not only would consider it, I've done it on many occasions. There's nothing magical about UACR <300 that eliminates the risk of CKD progression. The risk decreases but it's not an inflexion point. The lower the albuminuria, the lower the risk of progression, which has been well demonstrated in IgA...
Can sotalol initiation for atrial fibrillation be performed safely outpatient, and if so, what would be a reasonable protocol for implementing this?
In my opinion, sotalol (and Tikosyn) should never be initiated as an outpatient. We have all seen cases of torsades at some point in our careers related to sotalol initiation and QT prolongation, even when resuming a dose that was previously tolerated. There is a nice review article published in JAC...
Do you stop TNF inhibitors during the third trimester of pregnancy?
TNF inhibitor use in pregnancy is a common topic I review with patients. I make sure I include family members in my medication safety talks as well as provide tangible information, because unfortunately in the US there is a harmful stereotype that medications taken in pregnancy are bad and pregnant ...
Do you typically adjust pump settings for patients with diabetes who are on automated insulin pumps and fasting all day for religious reasons such as Ramadan?
I would decrease basal rate to 80% if well controlled but if not, continue the same.
What leads you to suspect that a foot drop is secondary to a myopathy rather than a neuropathic process?
Factors suggesting that a foot drop is due to a myopathy include: Clinical factors (slow progression (myopathy but also seen in CMT) versus acute or sub-acute onset (usually neurogenic), absence of sensory findings, absence of pes cavus, signs of facial or shoulder girdle weakness (FSHD can cause f...
What is your approach to managing ILD associated with inflammatory bowel disease?
We must first convince ourselves that the "ILD" relates to the underlying IBD. Patients may be on an immunomodulating regimen that increases the risk of opportunistic infections. The regimen itself may cause diffuse pneumonitis. Environmental/occupational exposures may also play a role. Armed with c...
