MKSAP8 Flashcards
What are Sjogrens pt at increased risk of? What other condition can cause a keratoconjunctivitis sicca type presentation?
DLBCL and MALT (Marginal zone) lymphomas of glands; GVHD can often present this way
What are sporadic fundic gland polyps assoc with?
Usually with PPI and require no tx; if FAP then assoc with APC gene mutation and can harbor dysplasia
What is the next best test to order if a patient has a positive HIV test?
T cell subsets as they may have full on AIDS (i.e. CD4 <200)
When can rituximab be used in RA? What labs do you need to check first?
Can be used if no response to MTX or TNF-alpha; check HBV serologies first as can reactivate; if + then entacavir or tenofovir
What is the difference in tx for OSA vs. CSA?
OSA = CPAP or BiPAP; CSA = Adaptive servoventilation; risk factors for CSA = afib or CHF
What should you consider doing in a patient diagnosed with Atypical Ductal Hyperplasia (ADH)?
Consider chemoprophylaxis as often can cause CA; tamoxifen if premenopausal or exemestane (or other AI; letrozole) if post
Tx of multinodular goiter with compressive sx
Total thyroidectomy
How is abdominal compartment syndrome usually defined?
New organ dysfunction in a patient with abdominal pressure > 20 mmHg (measured by bladder pressure); can have worsening respirations or increased peak pressures if on ventilator
What FEV1 cutoff is pulmonary rehab indicated for all patients w/ COPD?
Less than 50% and can be considered for some symptomatic or exercise limited patients >50%
What is the major difference between AIDP and CIDP?
Length of sx. AIDP will max out by 4 weeks; CIDP takes up to 8 weeks
A diagnosis of cushing requires how many screening tests?
- These include 24 hour urinary free cortisol, low dose dexamethasone suppression test, and midnight salivary cortisol
What are the effective treatments for idiopathic intracranial HTN?
The only really good medical tx are carbonic anhydrase inhibitors i.e. acetazolamide; Optic nerve fenestration is an operation to relieve intracranial HTN
What renal issue is HIV assoc with?
Collapsing Variant of FSGS
What disease should be on the DDx for patients with weird sensory sx and weakness that extends beyond 8 weeks of the onset?
CIDP - Chronic Inflammatory Demyelinating Polyneuropathy; diff from Guillian Barre or AIDP in the length of sx whereas AIDP hits its nadir within 4 weeks
What two populations are the most likely to get ABPA?
Asthma and Cystic Fibrosis
What should be tested for in all patients with metastatic melanoma?
BRAF V600E mutation and then give vemurafenib or dabrafenib if + (both BRAF inhibitors); recall BRAF part of MAPK pathway
What should be tested for in patients with FIXED Livedo reticularis (i.e. that remains despite changes in position or temp changes)
Antiphospholipid antibodies esp. if sx of thrombosis or multiple pregnancy loss
What are the imaging findings for adrenocortical carcinoma?
Large mass with irregular borders and calcification often with high attenuation (increased Hounsfield units) and a DELAY IN CONTRAST WASHOUT
What might a CT scan look like in a patient with Acute Hypersensitivity pneumonitis? The BAL?
Ground glass opacities with centrilobular nodules in the upper and middle lobes; Lymphocytic infiltrate on BAL often with low CD4:CD8 whereas sarcoid thought to be more CD4 bc granulomatous
What are the CD4:CD8 ratios in hypersensitivity pneumonitis vs. sarcoidosis?
Low in HP because there are more CD8 cells; High in sarcoid bc it is granulomatous inflammation; though there are recent challenges; The IMPORTANT thing is that the BAL is lymphocytic
How should a patient with myasthenic crisis be treated?
Emergently in an ICU w/ IVIG or PLEX (most often IVIG, no benefit one way or another); avoid quinolones
Drug of choice in anticholinergic toxicity and “nerve agent” bioterrorism
Physostigmine
