What is the utility of checking reverse T3 in clinical practice?
I have never routinely ordered it, only when forced to by certain rare patients who are reading Dr. Google or other information they find. They think it will change their plan, it never does.
In patients with active IBD and rectal cancer, do you take any precautions before starting TNT?
First, I would be sure that the patient really needs TNT. If a patient has active inflammatory bowel disease, they will not tolerate TNT very well. If a patient has inactive IBD, there is not likely to be much added morbidity. I would be very hesitant to use TNT if someone has really active IBD. The...
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.
