What is your practice for work up and treatment of incidental splenic infarcts with or without splenomegaly in patients without sickle cell disease?
I obtain CBC/diff, CMP, and LDH in all patients. I assume a CT of the abdomen has already been done because that is what usually leads to the diagnosis of incidental infarcts. Of course, it is important to rule out intra-abdominal pathology which should be visible by CT. I obtain a thrombophilia scr...
For treatment of ITP, what would you add to dexamethasone to achieve the fastest recovery in a patient waiting for a procedure?
I usually use IVIG, particularly if the patient has responded in the past.
How do you approach the symptomatic management of central vertigo in a patient with minimal improvement on (or contraindication to) meclizine?
Central vertigo is a difficult symptom to manage and can be frustrating for the patient (and their doctor). Depending on the etiology, treating the underlying cause would be the best first step (e.g. migraine prophylaxis). However, some causes of vertigo may be intractable or take a long time to rec...
How do you treat lupus-associated small fiber neuropathy?
Treatment of small fiber neuropathy associated with SLE consists mainly of symptomatic treatment for neuropathic pain and, if present, autonomic symptoms. Commonly used treatments for neuropathic pain include topical agents such as lidocaine, tricyclic antidepressants such as amitriptyline or nortri...
When staging prostate cancer, does MRI pelvis/prostate replace CT A/P?
The NCCN guidelines and recent NRG protocols allow for either CT or MRI to stage the pelvis. Assuming the MRI includes imaging of the pelvic LNs, I am not aware of an added benefit of a CT. With the increasing use of novel imaging for staging such as PSMA PET (which can be more sensitive at detectin...
Is LP indicated for patients with recurrent thunderclap headaches over a 4-week period and negative head imaging for SAH?
I think this depends on what kind of head imaging was done to rule out SAH. If the patient has had a totally normal head MRI and MRA (not only ruling out SAH, aneurysm but also RCVS), then LP is warranted to insure there is no inflammatory or infectious component as a cause for the headache. I think...
What is the significance of elevated fractionated catecholamines in POTS?
Dear Dr. @Dr. First Last,I don't think we understand the pathophysiology of POTS well enough to comprehensively answer this question.There are a number of technical issues that come into play when drawing serum catecholamines.First of all, many things can elevate catecholamines temporarily: exercise...
How do you manage osteonecrosis and pelvic insufficiency fractures after pelvic radiotherapy?
I have never seen osteoradionecrosis happen before in the pelvis. It should not happen in the range of doses that are tolerable in the pelvis due to the constraints imposed by the sacral plexus and the luminal GI organs. Sacral insufficiency fractures happen uncommonly, but are more common in female...
Do you avoid PTH/PTHrP analogs in patients with recurrent/severe CPPD?
I assume Dr. @Dr. First Last meant PTH-related bone-building drugs, not bisphosphonates, in his answer. I agree that I would use these drugs if needed in someone with CPPD disease, but I have not come across the scenario outlined in the question and am not aware of any data on the use of these drugs...
What is the differential for a patient with unilateral arm swelling, MRI with muscle edema, and markedly elevated CPK?
The differential for focal myositis is broad, although many times no obvious etiology is revealed and in that case, it is considered to be idiopathic. Etiologies that need to be ruled out are: malignancy (usually confirmed by biopsy), infections (like mycobacteria, viruses, fungi; usually will have ...
