Step3 21 Flashcards
First-line medications for migraine prevention
Beta-blocker
Valproate
TCAs
EHEC diarrhea presentation
Bloody diarrhea and abdominal pain without fever
Exposure to animals and /or undercook meat
Best strategy to prevent lung injury in an intubated patient with ARDS
Low tidal volume
Effects of mechanical ventilation on BP
Mechanical ventilation increases intrathoracic pressure
Collapses capacitance veins (inf. vena cava)
Decreases venous return
Decreases right heart preload
HYPOTENSION
Give IV fluids
Medications that cause pill esophagitis
Management
Tetracyclines NSAIDs K Fe Biphosphonates
Stop medication
Risk factors for developing fetal neural tube defects
Low folic acid intake
Medications: methotrexate, antiepileptics
Diabetes
Previous pregnancy with NTD
Prevention of neural tube defects
FOLIC ACID *at least 1 month before pregnancy
Regular population: 0.4 mg/day
High risk: 4mg/day Low folic acid intake Medications: methotrexate, antiepleptics Diabetes Previous pregnancy with NTD
Screening for Neural tube defects
AFP
Second-trimester ultrasound (to check on elevated AFP or even as first test)
Amniocentesis: if ultrasound fails
Positive AFP and cholinesterase
Rheumatoid arthritis medications safe in pregnancy
Hydroxychloroquine
Stop methotrexate 3 months prior to trying pregnancy
Normal vitamin B level
200-900
Clinical presentation
HEMOCHROMATOSIS
Skin, GI, Endocrine, Infecto, Cardiac, Mus/Ske
Skin: bronze diabetes
GI: Elevated liver enzymes, hepatomegaly (early), cirrhosis (late). Risk for Hepatocellular carcinoma
Endocrine: diabetes, hypogonadism (low libido), hypothyroidism
Mus/Ske: arthrarlgias, chondrocalcinosis
Cardiac: dilated or restrictive cardiomyopathy, conduction abnormalities
Infection: increased risk for listeria, yersinia, Vibrio vulnificus
Classic vignette for a patient with Hemochromatosis
Patient with diabetes and decreased libido
Elevated iron, ferritin, and transferrin
Diagnosis of hemochromatosis
Iron panel (elevated)
LFTs: elevated (mild)
Definitive diagnosis: gene testing
HFE
Treatment for bulimia
Cognitive-behavioral therapy first
Fluoxetine
(Hospitalize if severe or risk for suicide)
Bupropion can cause seizure in a patient with Bulimia
Important complications of nephritic sd
Thromboembolic events
Infection caused by typical organisms (not opportunistic)
