first aid key associations Flashcards
disease occurs in both males and females, inherited through females
mitochondrial inheritance
vitamin deficiency
folate (pregnant woman at high risk; body stores only 3-4 month supply; prevents neural tube defects)
gaucher disease
lysosomal storage disease
food poisoning (exotoxin mediated)
S aureus, B cereus
osteomyelitis
S aureus (most common overall)
bacterial meningitis (adults and elderly)
S pneumoniae
bacterial meningitis (newborns and kids)
group B strep/ E. coli, listeria monocytogenes(newborn), S pneumoniae, N meningitidis (kids/teens)
bacteria associated with gastritis, peptic ulcer disease, and gastric malignancies
H pylori
opportunistic infection in AIDS
pneumoncystis jiroveci pneumoniae
helminth infection (US)
ascaris lumbricoides
myocarditis
coxsackie B
infection secondary to blood transfusion
hepatitis C
osteomyelitis in sickle cell disease
salmonella
osteomyelitis with IV drug use
pseudomonas, candida, s aureus
UTI
E. coli, staph saprophyticus (young women)
C trachomatis (usually with N gonorrhoae)
STD
nosocomial pneumoniae
S aureus, pseudomonas, other enteric gram neg rods
pelvic inflammatory disease
C trachomatis, N gonorrhae
infections in chronic granulomatous disease
s aureus, e coli, aspergillus (catalase plus)
metastases to bone
prostate, breast > lung, thyroid, kidney
metastases to brain
lung > breast > prostate > melanoma > GI
metastases to liver
colon»_space; stomach > pancreas
S3 heart sound
increased ventricular filling pressure (eg, mitral regurgitation, HF), common in dilated ventricles
S4 heart sound
stiff/ hypertrophic ventricle (aortic stenosis, restrictive cardiomyopathy)
constrictive pericarditis
TB (developing world); idiopathic, viral illness (developed world)
holosystolic murmur
VSD, tricuspid regurgitation, mitral regurgitation
ejection click
aortic stenosis
mitral valve stenosis
rheumatic heart disease
opening snap
mitral stenosis
heart murmur, congenital
mitral valve prolapse
chronic arrhythmia
atrial fibrillation (assoc with high risk of emboli)
cyanosis (early; less common)
tetralogy of falot, transposition of great vessels, truncus arteriosus, total anomalous pulmonary venous return
late cyanotic shunt (uncorrected left to right becomes right to left)
eisenmenger syndrome (caused by ASD, VSD, PDA); results in pulmonary hypertension/polycythemia
congenital cardiac anomaly
VSD
secondary hypertension
renal artery stenosis, chronic kidney disease (polycystic kidney disease, diabetic neuropathy), hyperaldosteronism
aortic aneurysm, thoracic
marfan syndrome (idiopathic cystic medial degeneration)
aortic dissection
hypertension
aortic aneurysm, abdominal
atherosclerosis, smoking is major risk factor
aortic aneurysm, ascending or arch
tertiary syphillus, vasa vasorum destruction
sites of atherosclerosis
abdominal aorta > coronary artery > popliteal artery > carotid artery
cardiac manifestation of lupus
marantic/thrombotic endocarditis (nonbacterial)
heart valve in bacterial endocarditis
mitral > aortic (rheumatic fever), tricuspid (IV drug abuse)
endocarditis presentation associated with bacterium
S aureus (acute, IVDA, tricuspid valve), viridans stretococci (subacute, dental procedure), S bovis (colon cancer), culture negative ( Coxiella, Bartonella, HACEK)
temporal arteritis
risk of ipsilateral blindness due to occlusion of ophthalmic artery; polymyalgia rheumatica
recurrent inflammation/thrombosis of small/medium vessels in extremities
buerger disease (strongly associated with tobacco)
primary cardiac tumor in kids
rhabdomyoma, often seen in tuberous sclerosis
cardiac tumor in adults
metastasis, myxoma (90% in left atrium; “ball valve”
21-hydroxylase deficiency
congenital adrenal hyperplasia, hypotension
cushing syndrome
iatrogenic (from corticosteroid therapy); adrenocortical adenoma (secretes excess cortisol); ACTH- secreting pituitary adenoma (cushing disrase); paraneoplastic (due to ACTH secretion by tumors)
tumor of adrenal medulla, kids
neuroblastoma (malignant)
tumor of adrenal medulla, adults
pheochromocytoma (usually benign)
cretinism
iodine deficit/ congenital hypothyroidism
