deck 31 Flashcards
(48 cards)
pathophys of acute massive PE
abrupt increase in RA pressure –> decreased venous return to LA –> decreased CO + hypotension + obstructive shock
acute HIV infection
mononucleosis like syndrome consisting of fever + night sweats + lymphadenopathy + arthralgias + diarrhea
indications for antimicrobial prophylaxis for tick bites
1) adult tick or nymphal exodus scapularis
2) tick attached for longer than 36 hours or engorged
3) prophylaxis started within 3 days of tick removal
other meds that can cause hearing loss
aspirin + loop diuretics
indications for hep c screening
1) injection drugs
2) needlestick
3) blood transfusion before 1992
chlamydia on testing
Culture-negative
won’t show up as bacteria on UA
most common valvular abnormality detected in patients with infective endocarditis
mitral valve disease (usually MVP w/ coexisting mitral regurgitation)
nasal polyps associated with
chronic rhino sinusitis
asthma
aspirin-exacerbated respiratory disease (AERD)
nasal polyp presentation
bilateral nasal obstruction + nasal discharge + anosmia
Aspirin exacerbated respiratory disease (AERD)
- asthma, chronic rhino sinusitis with nasal polyposis and bronchospasm or nasal congestion following ingestion of aspirin or NSAIDS.
malignant (necrotizing) otitis externa (MOE)
severe infection of external auditory canal and base of skull usually caused by pseudomonas aeruginosa
- usually happens in old people with bad diabetes
- presents with severe pain + purulent drainage with a sense of fullness
abx with good pseudomonal coverage
ciprofloxacin
most common cause of hearing loss in AIDS patients
- serous otitis media (presence of middle ear effusion without signs of infection)
(lymphadenopathy or lymphomas cause auditory tube dysfunction) - leads to conductive hearing loss
treatment for syphilis patient with penicillin allergy
doxy
problem with monospot
25% false-negative rate during first week of illness
common complaint with presbycusis
difficulty hearing in crowded or noisy environments
- high-pitched noises or voices
heamophilus ducreyi presentation
papule that progresses to an ulcer
labs in endocarditis
normocytic anemia + high ESR
RF can be positive
diagnosis of histoplasma
urine or serum antigen assay
vaccines for patients with chronic liver disease
hep A,B, PPSV23, Tdap
potential complication of upper GI endoscopy
aspiration pneumonia due to anaerobes
other vibrio vulnificus infection
Often cause wound infections that can be mild, but may develop rapid-onset, severe necrotizing fasciitis with hemorrhagic bulls lesions and septic shock. Patients with liver disease are at high risk.
treatment of choice for pregnant and lactating patients with early localized lyme disease
amoxicillin (can’t give CTX because it’s only IV and would require hospitalization and exposure to other microbes)
pyelo usually caused by…
e coli
