DIT crashcart notes Flashcards
Non-invasive coronary heart disease tests
Stress echocardiography
Stress electrocardiogram
-Stress tests by treadmill or dobutamine
radionuclide myocardial perfusion imaging
Coronary artery calcium
Cardiac computed tomography angiopgraphy
Why are b-blockers contraindicated in pts with cocaine-induced angina and cocaine induced hypertension
Cocaine inhibits the reuptake of NE by the presynaptic neuron prolonging the effects of NE
NE works through the alpha and beta adrenergic receptors on vascular smooth muscle, including coronary arteries.
Beta blockers lead to unopposed alpha adrenergic activity leading to angina, MI, HTN
How is acute DIC diagnosed?
CBC: Thrombocytopenia - platelets less than 100K
Elevated D-dimer: increased fibrin degradation products (FDP)
Prolonged PT and PTT (d/t consumption of coagulation factors)
Decreased fibrinogen
Reduced antithrombin, protein C and protein S
What are the causes of DIC?
Sepsis or severe infections: GN or GP
Trauma
Obstetric complications
Acute pancreatitis
Malignancy
Transfusion reactions
Ddx for RUQ pain
Cholecystitis, cholangitis, liver abscess
Ddx for LUQ pain
splenic rupture
Ddx for epigastrium pain
PUD, pancreatitis
Ddx for RLQ pain
appendicitis, renal stones, ectopic pregnancy, ovarian torsion, PID
Ddx for LLQ pain
Diverticulitis, renal stones, ectopic pregnancy, ovarian torsion, PID
Clinical presentation of a spontaneous vs tension pneumothorax
Spontaneous: Young adults, rupture of emphysematous blebs, at rest
Tension: after blunt trauma
Tracheal deviation in a spontaneous vs tension pneumothorax
Spontaneous: slight to ipsilateral side
Tension: trachea and mediastinum shifts significantly to contralateral side
Breath sounds in a spontaneous vs tension pneumothorax
Spontaneous: decreased
Tension: absent
Treatment of a spontaneous vs tension pneumothorax
Spontaneous: observation, supplemental O2, may need chest tube
Tension: immediate needle decompression, (thoracentesis), chest tube (thoracostomy)
Hypertension + hypokalemia
Primary hyperaldosteronism (Conn's) -aldosterone secreting adenoma
Hyponatremia + hyperkalemia + hyperpigmentation
Primary adrenal insufficiency (Addison’s) - will also have hypotension
Hypocalcemia + hyperphosphatemia + low PTH
Hypoparathyroidism
Features of nephrotic syndrome
caused by damage to glomeruli
Proteinuria >3.5 g/24 hrs Hypoalbuminemia Edema Hyperlipidemia Hypercoagulability
Causative pathogens associated with osteomyelitis
MC: Staph aureus
IV drug use: S. aureus, Pseudomonas
Sickle Cell disease: S. aureas, Salmonella spp.
Diagnostic criteria for SLE
At least 4 of the 11
Malar rash Discoid rash Photosensitivity Oral ulcers Arthritis Serositis \+ ANA Renal disease Neurological d/o (seizures, psychosis) Hematologic d/o (hemolytic anemia, leukopenia, thrombocytopenia) Immunlogic d/o (anti-dsDNA, anti-Smith, anti-phospholipid)
DKA lab abnormalities
Increased serum glucose (>250) Increased plasma osmolality High anion gap metabolic acidosis \+ ketones in serum and urine Normal or elevated serum K+ but low total body K+
Classic symptoms of Sjogren syndrome
dry eyes - sand in eyes
dry mouth - difficulty swallowing, tooth decay, parotid enlargement
Arthralgias
Other: Dry skin, nasal passages, vagina
Diagnostic criteria for DM
One of the following criteria:
fasting plasma glucose >126 mg/dL
OGTT: Plasma glucose >= 200 mg/dL 2 hours after 75 g glucose load
Random plasma glucose >= 200 mg/dL with symptoms of hyperglycemia (polyuria, polydipsia)
hemoglobin A1c >= 6.5
Pts that ACE inhibitors are considered first line treatments for essential htn
CHF or asx LV dysfunction - reduce mortality
Hx of STEMI - reduce mortality in post MI
Hx of NSTEMI w/:
- anterior infarct
- DM
- systolic dysfunction
Proteinuric CKD - slow progression of proteinuria
Pts that ACE inhibitors are contraindicated
Pregnancy - teratogenic (fetal kidney problems)
Hx of angioedema from ACEI
B/l renal artery stenosis
Profound fatigue with Heinz bodies and degmacytes (bite cells) on peripheral smear - most likely dx and cause of fatigue
G6PD deficiency
G6PD generates NADPH - needed to reduce glutathione which neutralizes ROS and hydrogen peroxide
Without G6PD - RBCs are susceptible to oxidation, which leads to hemolytic anemia
Drugs provoking hemolytic anemia in G6PD deficiency
“Spleen Purges Nasty Inclusion From Damaged Cells”
Sulfonamides Primaquine (antimalarial) Nitrofurantoin Isoniazid (INH) Fava beans Dapsone Chloroquine (antimalarial)
ST elevation in I, aVL, V5-6
Lateral wall MI
Circumflex artery
ST elevation in II, III, aVF
Inferior wall MI
Posterior descending artery, usually d/t RCA occlusion (if right dominant heart), 10% have left dominant which is off of circumflex a.
ST elevation in V1-V4
Anterior wall MI
LAD
Seronegative spondyloarthropathies
assoc w/ HLA-B27
"PAIR" Psoriatic Ankylosing spondylitis IBD arthritis Reactive arthritis
Asymmetric arthritis preceded by GI or GU infection
Reactive arthritis
“can’t see, can’t pee, can’t climb a tree”
Inflammatory back pain + “bamboo spine” on x-ray
Ankylosing spondylitis
Skin plaques with silvery scaling + pitting of nails + arthritis
Psoriatic arthritis
