Q

What are the CD4:CD8 ratios in hypersensitivity pneumonitis vs. sarcoidosis?

A

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

Explain the issues of the A1C in ESRD?

A

Can be falsely elevated due to carbamylated hgb due to uremia, falsely low due to anemia of CKD; need to really look at fasting sugars and post prandial

Q

Tx of multinodular goiter with compressive sx

A

Total thyroidectomy

24
Q

Which HLA markers are associated with Celiac dz?

A

HLA-DQ2 and HLA-DQ8

25
Q

What are the effective treatments for idiopathic intracranial HTN?

A

The only really good medical tx are carbonic anhydrase inhibitors i.e. acetazolamide; Optic nerve fenestration is an operation to relieve intracranial HTN

26
Q

What FEV1 cutoff is pulmonary rehab indicated for all patients w/ COPD?

A

Less than 50% and can be considered for some symptomatic or exercise limited patients >50%

27
Q

What kind of kidney injury do PPIs cause (if you believe it)?

A

Tubulointerstitial; Chronic tubulointerstitial dz often arises from an acute tublointerstitial insult but can occur subacutely as well

28
Q

What test would you need in order to diagnose acute HIV?

A

Nucleic acid amplification test as the antibody may be negative (window period); So a positive antigen/antibody test tells you pt EITHER has p24 antigen or antibody

29
Q

What is the next best test to order if a patient has a positive HIV test?

A

T cell subsets as they may have full on AIDS (i.e. CD4 <200)

30
Q

What is the best tx for bone-only breast CA metastases?

A

Aromatase inhibitors i.e. if patient has been free of dz for a while and gets bone mets start an AI (exemestane) and if they are resistant to that add everolimus (mTOR inhib); chemo with paclitaxel may be used instead if pt is hormone neg or has impending visceral crisis

31
Q

Name a non-SLE vasculitis that often causes fevers, abdominal pain, and peripheral mononeuropathies (mononeuritis multiplex)

A

Polyarteritis Nodosa (assoc with HBV)

32
Q

What are the steps if a patient has low ACTH but high cortisol? High ACTH and high cortisol?

A

This is ACTH independent so scan adrenals; if ACTH high then MRI pituitary or petrosal venous sampling OR consider ectopic ACTH production

33
Q

A diagnosis of cushing requires how many screening tests?

A
  1. These include 24 hour urinary free cortisol, low dose dexamethasone suppression test, and midnight salivary cortisol
34
Q

What is the first line tx for sympathomimetic overdose syndromes (i.e. cocaine, meth, bath salts)

A

Benzos are first line drugs; other supportive care includes intubation, evaporative cooling/cooling blankets, and consideration that they may develop rhabdo

35
Q

Drug of choice in anticholinergic toxicity and “nerve agent” bioterrorism

A

Physostigmine

36
Q

What disease should be on the DDx for patients with weird sensory sx and weakness that extends beyond 8 weeks of the onset?

A

CIDP - Chronic Inflammatory Demyelinating Polyneuropathy; diff from Guillian Barre or AIDP in the length of sx whereas AIDP hits its nadir within 4 weeks

37
Q

What is the major difference between AIDP and CIDP?

A

Length of sx. AIDP will max out by 4 weeks; CIDP takes up to 8 weeks

38
Q

What test can suggest presence of tuberculous effusion? Confirmatory?

A

ADA level (less than 40 rules it out; high NPV) and a pleural biopsy is required to confirm; suspect in pt w/ lymphocytic predominant pleural effusion

39
Q

T/F a positive sputum culture will show Mycobacteria in patients with suspected tuberculous effusions

A

False (kind of); it will only show it if there is also pulmonary parenchymal disease; a patient with a possible tuberculous effusion should have ADA level checked and pleural bx and should not be considered ruled out only on the basis of negative sputum Cx

40
Q

What disorder will have differential cyanosis on physical exam i.e. cyanosis and clubbing in lower body but not upper

A

Patent Ductus Arteriosus (PDA) with Eisenmenger physiology

41
Q

What is the difference between D-lactic acidosis and Type B lactic acidosis?

A

D-lactic acidosis occurs in patients w/ SIBO etc. as the bacteria produce the D enantiomer of lactate; Type B lactic acidosis is still the regular L-Lactate picked up on lab tests but occurs due to inability to clear lactate as opposed to excess production

42
Q

What should you do in a patient with hyperalbuminemia or MM with HYPOcalcemia?

A

Order ionized calcium as these situations may have more protein binding to albumin

43
Q

How do you treat a sickle cell pain crisis in pregnant patients?

A

Same as for a normal pt i.e. fluids, narcotics, etc; if worsening or signs of fetal distress then would transfuse

44
Q

Why should you perform a radical inguinal orchiectomy in patients with metastatic testicular cancers?

A

Because there is a blood-gonadal barrier that can prevent chemo from getting into the testis

45
Q

What renal issue is HIV assoc with?

A

Collapsing Variant of FSGS

46
Q

How should you manage a pt who undergoes a RUQ US and findings of a 2 cm polyp are found?

A

Cholecystectomy even if asymptomatic; any polyp >1 cm needs to come out bc can be cholangio; otherwise can be followed unless pt has PSC

47
Q

What is the purpose of ambulatory pH testing in pt w/ GERD?

A

Can be done if atypical sx of GERD to see if that is the cause or if ongoing sx while on PPI to see if there is adequate acid suppression; if not can do Nissen

48
Q

What is the concern for a patient with prolactinoma who gets pregnant?

A

They can grow in response to estrogen and so need to carefully monitor for changes in vision; additionally can get Sheehan syndrome after delivery

49
Q

Vesicles on tip of nose suggestive of VZV is known as __________. Who to call?

A

Hutchinson Sign; Ophtho

50
Q

In whom are air filters in IV lines important?

What two populations are the most likely to get ABPA?

A

Asthma and Cystic Fibrosis

Q

What is the best mgmt for an advanced Parkinson pt who benefits from anti-parkinsonian meds but has bad side effects?

Deep Brain stimulator to subthalamic nucleus; most approp first steps when DA agents work but wear off are to increase dose of carbidopa/levodopa and then to ADD entacapone

54
Q

What are sporadic fundic gland polyps assoc with?

A

Usually with PPI and require no tx; if FAP then assoc with APC gene mutation and can harbor dysplasia

55
Q

What should you do if you suspect hypothyroidism but pt has low or normal TSH?
