Medicine Flashcards
Night/morning headaches +morning vomiting + fever
Brain abscess
-do head CT
Follicular Thyroid cancer Dx
- FNA will show follicular cells
- you need to show invasion through capsule to differentiate btwn carcinoma and a follicular adenoma
- mets hematogenously
Papillary thyroid carcinoma
- COMMONEST thyroid cancer
- look for Psammoma bodies,
- FNA shows large cells with ground glass cytoplasm, inclusion bodies in pale nuclei and central grooving. Encapsulated
- Prognosis is really good even if there are mets
ITP Immune Thrombocytopenia
Presentation: previous viral infection (URI), petechia and bruises, bleeding (epistaxis, GI bleeds, hematuria)
-Labs: isolated thrombocytopenia and big platelets w/ nothing else
-Kids tx: just skin findings? then observe
-Bleeding? give IVIG or glucocorticoids
-Adults: Platelets >30k? observe
-
Pt had a heart attack and passed out. Why?
-b/c of some sort of ventricular arrhythmia. Probably V fib
Nonallergic vs allergic rhinitis
Nonallergic: stuffiness, congestion, postnasal drip w/ dry cough, NO identifiable triggers, perennial sx that worsen w/ season change
-tx: intranasal antihistamine or glucocorticoid
Allergic Rhinitis: pts have mainly eye sx (itching), sneezing, pale blueish nasal mucosa,
-Tx: same
Meds a PT should be on if they had an MI, have unstable angina or got PCI
- B-Blocker
- Aspirin
- ACEI
- Lisinopril
- Clopidogrel
- the first 4 should be used in pts to prevent an MI
Uric Acid stone tx
Potassium citrate to alkalinize the urine
-radiolucent
Lumbar spinal stenosis
- Presents as lower back pain and pain in legs/difficulty walking.
- Results from anything that narrows the spinal canal and compresses that nerve roots.
- Most commonly from degenerative joint disease where disc herniation and osteophytes hurt the roots
- Worse=standing and downhill walking (flexion (leaning back))
- Better=uphill walking and leaning forward (less pressure on roots)
- DX=MRI!!!! Really small spaces so yea MRI
Avoid sun exposure w/ this antibiotic
Tetracycline
Kidney stone dx
Ultrasound or NONCONTRAST CT
Massive pulmonary embolus sx
-you can see syncope and signs of right heart strain (right bundle branch block, nonspecific ST-T wave changes, hypotension, JVD), cariogenic shock causing CNS manifestations like blown pupils
Myasthenia Gravis tx
-Step 1?
2?
Crisis?
1) Pyridostigmine for all
2) if sx continue then add glucocorticoids, azathioprine, mycophenolate mofetil, and cyclosporine
Crisis: do Glucocorticoids AND IVIG or Plasmapharesis
-Infection is usually the cause of the crisis
CMV retinitis
- does NOT hurt
- commonest ophtho complication in HIV
HSV retinitis
hurts!! Also has initial sx of keratitis and conjunctivitis
Tx of COPD
- O2 (target is88-92%)
- Inhaled bronchodilators (albuterol, ipratropium)
- SYSTEMIC GLUCOCORTICOIDS
- Antibiotics if more than one of the following: cough, increase in sputum production/weird color, or dyspnea
- PEEP if not too bad, intubate if really bad
Diastolic Heart Failure
- Normal ejection fraction
- Due to decreased ability of LV to fill. Usually from chronic HTN leading to a thick LV.
Albuminocytologic dissociation
Guillain-Barre
High CSF protein w/ normal cell count
When to use whole blood transfusion?
-Only when the pt is in major trauma and needs a MASSIVE transfusion. The vast majority of the time you need to choose PRBCs
HIV pt w/ unilateral hearing loss?
-Likely it’s noninfectious serous OM. Happens in HIV pts p/c of lymphadenopathy. Exam shows dull and hypomobile TM
Chalazion
- nodular rubbery lesion that causes PAINFUL swelling.
- If they are recurrent or persistent then they might be due to sebaceous carcinoma or basal cell so do histopathological examination.
Lifestyle modification for HTN tx efficacy (1 to 5)
1) Weight loss (10kg)
2) Dash Diet
3) Exercise
4) low sodium diet
5) DRINK 2/day for men and 1/day in women
- Notice how SMOKING has NOTHING to do with any of this crap!! It does not raise blood pressure in the long term
Enthesitis
- pain where tendons insert into bone
- Usually associated with HLA-B27 and most commonly ankylosing spondylitis.
- Heel, tibial tuberosities and iliac crest pain is most common.
CAP
- 3 commonest causes
- healthy pt tx?
- really sick old person tx?
Strep pneumo, H flu and Mycoplasma
Healthy: tx outpatient w/ Doxyclycline or a Macrolide
Super sick: hospitalize and tx w/ extended-spectrum fluoroquinolones (Levofloxacin or Moxifloxacin), or you could give a B-lactam w/ a Macrolide.
Antiphospholipid antibody syn
- what antibody?
- sx?
anti-cardiolipin
-recurrent thrombosis, loss of pregnancy, cognitive deficits, or microangipathic hemolytic anemia
Diastolic murmur work-up
ALL should be worked-up!!
-Do an echo
Langerhans cell histiocytosis
- in bone it presents as a lytic long bone lesion w/ pain and high calcium. Associated w/ pathologic fractures. Usually in children.
- differential is primary hyperparathyroidism (parathyroid adenoma) which can explain the lytic bone lesion, pain and hypercalcemia but this is usually in pts 50+ and not in kids.
Pneumocystis pneumonia
-in HIV pts w/ CD4 counts
Staph pneumonia
OBVIOUSLY is from IV drug users!!
-causes cavitary lesions
Pneumonia in a HIV pt
- most likely Strep pneumo
- presents w/ lobar pneumonia and high fever. Pleural effusion is common.
- encapsulated organisms in general are common infections in HIV+ pts b/c they can’t fight them off
Lyedig cell tumor
- commonest type of testicular sex cord tumor (in al age groups)
- Lyedig cells make testosterone but can also make estrogen b/c they have aromatase. The estrogen will inhibit LH and FSH
- Labs: high testosterone and estrogen, low FSH and LH. NO increase in AFP or B-HCG!!!
- adults may have geinicomastia and kids may have precocious puberty
Yolk sac tumor
-increase in AFP “the yolk has lots of protein”
FSGS
- think of FSGS if the pt is black, fat, uses heroin and/or has HIV.
- commonest cause of nephrotic syndrome in adults
Membranous nephropathy
-associated w/ Hep B, adenocarcinoma (breast and lung), NSAIDS and SLE
Brain abscess
- 3 commonest bugs (or classes)
- what if pt has sinusitis?
- What about hematogenous spread?
- tx?
- S. viridans (anaerobe), Staph aureus, and G- bugs
- Sinusitis: bug is gonna be S. viridans or some other anaerobe (peptostreptcoccus)
- Hematogenous spread: gonna be Staph aureus or or a G-
- TX: prolonged antibiotics (4-8 week minimum!) and you should probably aspirate it and culture.
Complications of an MI MONTHS later? 2
- ventricular aneurism: PERSISTENT (like months later) ST-segment elevation and Q waves in exact same leads as original MI. Large ones can lead to L heart failure and can dilate the mitral valve w/ regurg
- pericarditis
How to prevent diabetic nephropathy?
Intensive HTN control (NOT GLYCEMIC CONTROL!!)
Antibodies for resolved Hep B infection
Antibodies for Hep B vaccination
- Resolved infection: + anti-HBs and anti-HBc but neg for HBsAG
- Immunized: + for anti-HBs. neg for anti-HBc and and HBsAG
What brings K+ into cells? 3
1) bicarb
2) insulin and glucose
3) B-2 agonists
Progressive Multiform Leukoencephalopathy
- virus?
- what shows on the CT?
- tx/prognosis?
- JC virus
- lesions do NOT produce mass effect. Pts usually present w/ disturbances in speech, vision and gate
- CT: multiple demyelinating (leuko… duh), non-enhancing lesions
- No tx and life expectancy is 6 months
Think you have a melanoma? next step?
- do excisional biopsy w/ narrow margins
- Depth of lesion is 1mm: then do 1cm margins and prog is 99% 5 year survival
Where did the pulmonary embolus clot come from?
An iliofemoral vein clot
Paget’s disease of the breast
- ulcerating, exematous rash on the nipple
- most of the time there will be adenocarcinoma associated w/ it.
- Skin biopsy demonstrates large cells that are surrounded by clear halos
Digitalis toxicity
-arrhythmia that is most specific?
- Dig will increase the ectopy of atria and ventricles. It also increases vagal tone and promotes AV block. This combo leads to…
- Atrial tachycardia w/ AV block.
Pt clearly had a stroke. What do you order next?
CT of the head WITHOUT contrast to rule out hemorrhage
What do you order to dx kidney stones?
US if it is an option.
If not, then CT scan of abdomen WITHOUT contrast b/c this can detect both radiolucent and radiopaque stones
-Big doses of Vitamin D leads to formation of Oxalate stones
-Dietary recommendations: decrease protein and oxalate, decrease sodium, more water and more dietary Calcium (weird!)
Cardiac Tamponade histrory/sx/physical
- recent URI, dyspnea, JVD, CLEAR lung fields, big freakin heart and NONPALPABLE PMI!
- Beck’s triad: hypotension, JVD and muffled heart sounds
Vitamin K gamma carboxylates
Factors II, VII, IX, X, protein C and S
-don’t forget that CF pts can had a def in Vit K (fat soluble) and thus could have a deficiency in any of these.
Multiple System Atrophy
Shy-Drager Syndrome
- Parkinsonism
- Autonomic dysfunction (postural hypotension, abnormal sweating, bowel/bladder dsfxn, abnormal lacrimation, impotence, gastroparesis, etc..)
- Widespread neurologic signs (cerebellar, pyramidal, lower motor neuron)
- TX: symptomatic. Antiparkinsonism drugs don’t work
Interstitial cystitis
- Painful bladder syndrome
- kinda presents like endometriosis but no cervical motion tenderness, just tenderness when palpating the anterior vaginal wall.
- associated w/ psychiatric illnesses and pain fibromyalgia
- tx: TCAs and symptom management
- c/c to a cystocele (will have prolapse)
Tick removal?
Stinger removal?
- tweezers
- scrape w/ a tongue depressor
Pronator drift due to?
Upper motor neuron lesion
NOT cerebellar dsfxn!!
Tactile fremitus, Auscultation
- Consolidation (lobar pneumonia)
- COPD
- Effusion
- Pneumothorax
- Increased, bronchial breath sounds, bronchophany, egophany, pectoriloquy
- Decreased, decreased
- Decreased, decreased
- Decreased, decreased
Tx of solitary brain tumor at grey-white junction?
what if it is deep?
- surgical resection
- whole brain irradiation. Also do this for multiple mets
Succinylcholine. Risk and who is it C/I in?
- can cause crazy hyperkalemia which can lead to arrhythmias.
- C/I in pts w/ hyperkalemia (could be a burn victim or rhabdo pt!)
Acute bronchitis clinical picture
-pt presents w/ a few days of a viral illness that progressed to yell sputum (sloughed epithelial cells) and some hemoptysis (infection eroded bronchial wall so that’s the bleeding… not freaking TB!). CXR will show nothing at all. Supportive care.
Primary biliary cirrhosis
- typical pt is a middle aged female who presents w/ PRURITIS and probably fatigue.
- Alk phos, IgM and cholesterol are high. Bump in transaminases.
- PE shows hepaotsplenomegaly and xanthomatous lesions on eyelids, skin, tendons.
- Anti-mitochondrial antibodies
- increase risk of hepatobiliary malignancy
- TX: ursodeoxycholic acid but eventually a liver transplant w/in a decade or death.
tx of Syphilis if non-pregnant pt has penicillin allergy?
PO Doxycycline for 14 days (28 days if latent)
-Remember, you can’t give doxy to preggos
Tx of dissecting aortic aneurism
B-Blocker b/c they simultaneously lower BP and HR
Multiple myeloma
- combination of back pain, anemia, renal dsfxn, and elevated sed rate.
- Also some pts will have hypercalcemia which will lead to things like constipation, weakness, polyurea
