Cards

Term
nafcillin, methacillin, oxacillin are resistant to what?

MRSA gets resistance to these how?
Definition
beta lactimases

alteration in PBP structure (no production of beta lactimases)
Term
Oocytes are arrested in what phase:
- in ovary
- after ovulation
Definition
- prophase I
- metaphase II
Term
blind as a bat, mad as a hatter, red as a beet, hot as a hare, dry as a bone, the bowel and the bladder lose their tone, and the heart runs alone
Definition
atropine poisoning

(urinary retention & constipation)
Term
Giardia:
- Where does it adhere?
- What prevents adherance?
Definition
- duodenum & jejunum
- secretory IgA
Term
tetrad of narcolepsy
Definition
1) excessive daytime sleepiness
2) cataplexy (loss of muscle tone w/out loss of consciousness)
3) hypnagogic/hypnopompic hallucinations
4) sleep paralysis (can't move after waking)
Term
what is the last cell type to be lost in the bronchial tree? where is it lost?
Definition
- cilliated cells
- respiratory bronchioles
Term
type of urethral injury in:
- pelvic fracture
- straddle injury
Definition
- Posterior urethra (btw bladder & prostate)
- anterior urethra (after prostate & below UG diaphragm, before urethra enters spnogiosum)
Term
in mitral stenosis, the interval between these 2 sounds inversely correlates w/ the severity of the disease?
Definition
A2 & OS (opening snap)

the higher the diastolic pressure, the closer it'll be to the end systolic pressure --> the sooner the mitral valve opens
(see question 12 on test 15)
Term
name sequence of events that lead to pulmonary HTN in LV failure
Definition
decreased LV SV --> increased LA pressure --> venous congestion --> pulmonary edema --> alveolar collapse --> hypoxia --> reactive vasoconstriction
Term
What step in glycolysis needs all the cofactors?
Definition
alpha-ketoglutarate --> succinyl CoA

Need: thiamine, lipoic acid, CoA, FAD, NAD+

(question where alcoholic gets dextrose w/out thiamine --> acute exacerbation of wernicke encephalopathy: confusion, ophthalmoplegia, ataxia)
Term
majority (80%) of deaths in cystic fibrosis?
Definition
pneumonia
Term
superior SMA syndrome
Definition
SMA compresses transverse duodenum causing intestinal obstruction

occurs after aortomesenteric angle decreases: crash diet (diminished mesenteric fat), lordosis, surgical correction of scoliosis
Term
C.diphtheriae:
- shape?
- what does it grow on?
- disease?
- toxin?
Definition
- chinese letters
- tellurite agar (black colonies); loffler's medium (metachromatic granules w/ methylene blue staining)
- pseudomembrane/airway obstruction; if systemic: myocarditis & polyneuritis
- AB toxin --> ribosylates & inhibits EF-2 (if systemic, causes myocarditis/polyneuritis)
Term
hypokalemia & hypomagnesemia w/ this antifungal
Definition
ampho B (notorious for its renal toxicity)

renal toxicity causes electrolyte disturbances listed which predisposes to arrhythmias (torsades included)

In addition, renal toxicity decreases EPO, which causes anemia

OTHER SE: shake& bake & IV thrombophlebitis
Term
MOA of anastrozole

MOA of ketoconazole

MOA of trastuzumab
Definition
aromatase inhibitor

inhibits androgen synthesis

HER2/neu receptor antagonist
Term
what donates a nitrogen to citrulline in urea cycle to make arginosuccinate?
Definition
aspartate
Term
local, cutaneous effects of chronic topical corticosteroid administration
Definition
- atrophy/thinning of dermis (loss of collagen, drying, cracking, +/- tightening of skin)
--atrophic striae
- telangiectasias
- ecchymoses


latter 2 from mild trauma
Term
skin rash, photosensitivity, arthralgias (migratory), and renal disease in a young woman
Definition
SLE: autoimmune, multisystem vasculitis
Term
DOC for trigeminal neuralgia
Definition
carbamazepine
Term
MOA of selegiline
Definition
MAO-B inhibitor (decreases dopamine metabolism in brain)
Term
differentiate simple-partial & complex-partial seizures
Definition
partial seizure: only affects one part of the body (e.g. myoclonic jerks in right arm)

SP: no loss of consciousness
CP: loss of consciousness
Term
person treated for seizures --> comes back w/ blood dyscrasias (aplastic anemia, agranulocytosis, thrombocytopenia, etc)
Definition
carbamazepine

also is hepatotoxic (monitor LFTs) & associated w/ SIADH!
Term
- what binds mRNA first: 30S or 50S?

- Which subunit has the peptidyltransferase function?
Definition
- 30S: 16S porthion; has "Shine-Dalgarno sequence" that binds the mRNA ~10 bases upstream of AUG (next steps: initiator tRNA binds AUG --> 50S joins complex --> protein synthesis)

- 50S (23S subunit)
Term
areas succeptible to ischemia in brain?
Definition
First: pyramidal cells of hippocampus

other areas: watershed areas; purkinje cells of cerebellum
Term
3 things people w/ asbestos exposer may develop:
Definition
1) asbestosis
2) bronchogenic carcinoma
3) mesothelioma

NOTE: bronchogenic carcinoma most common; mesothelioma is #2!
Term
cancer w/ beta-naphthylamine exposure
Definition
bladder carcinoma

(this is a compound that is found in cigarette smoke)
