Q

How do you calculate the sensitivity of a test? What does it refer to?

A

Sensitivity: ability of a test to correctly identify individuals with a disease. More true positives, fewer false negatives
Sens = TP/(TP+FN)

A

Paroxysmal supraventricular tachycardia

20
Q

EKG: short PR, delta at beginning of QRS, wide QRS

Diagnosis?

A

Wolff-Parkinson-White, associated with development of AVRT. Increased risk of symptomatic paroxysmal SVT

AC (heparin, etc.)
24

NYHA class II-IV (presence of ANY Sx)
LBBB with QRS >150msec

25
Treatment for group 1 (idiopathic) pulmonary hypertension
Dual therapy: Endothelin receptor antagonist (bosentan, ambrisentan) + phosphodiesterase 5 inhibitor (tadalafil, sildenafil)
26
Characteristics of pain associated with lumbar spinal stenosis
Disappears/decreases when sitting down Increases with spine extension Decreases with spine flexion
27
murmur of VSD?
harsh holosystolic at left 3rd/4th intercostal space, often with palpable thrill
28

Nitrofurantoin Cephalexin Fosfomycin Amox-clauv NO BACTRIM -> NT defects No tetracyclines, no flouroquinolones
30
Antibiotics for pyelo in pregnancy?
Ceftriaxone or cefepime until afebrile >48hrs, then switch to oral for 10-14 d
31
How to confirm diagnosis of sarcoid?
Excisional lymph node biopsy -> see noncaseating granulomas | And rule-out other etiologies (e.g. TB)
32
Multifocal atrial tachycardia: Often secondary to? EKG findings?
Often secondary to: acute exacerbation of underlying pulmonary disease, right atrial enlargement, catecholamine surge (as in sepsis), electrolyte imbalance EKG findings? P waves of at least 3 different morphologies, irregular R-R intervals, atrial rate >100
33
Palpable purpura in gravity-dependent areas, abdominal pain, arthralgias in child?
HSP + IgA nephropathy, later finding abdominal pain from small bowel intussusception
34
Calcium and phosphate derangements in CKD?
1) decreased filtered phosphate -> phosphate retention, binds Ca, lowers free Ca, rise in PTH 2) decreased conversion to 1,25-vitamin D -> decreased intestinal Ca absorption 3) Secondary hyperparathyroidism due to above 4) can lead to autonomous PTH secretion (tertiary hyperparathyroidism) unresponsive to rising Ca -> bone pain, high alk phos -> needs parathyroidectomy
35
Adverse effects of amiodarone?
``` Pulmonary toxicity Photosensitivity Skin discoloration Thyroid dysfunction Bone marrow suppression Abnormal LFTs ```
36
Most common bug in erysipelas?
Group A strep
37
