Describe Serology for Hepatitis B -7
S - SEC - SCEb - Core - CEbSAb - CSAb - SAb
- unvaccinated pts acutely exposed to Hep should STILL get vaccinated in addition to the immunoglobulin*
- CSAB = RESOLVED HEP B INFECTION*
Patient p/w isolated elevation of [total anti-HBc (Core Ab)]
What does this indicate? -3
- [window of acute HBV] = subclinical hepatitis (⇪ IgMCore and ⇪ LFT)
- Years after recovery from acute HBV once SAb has waned. (no IgMCore)
- Years after chronic HBV once (S antigen) has waned (no IgMCore)
____________________
S - SEC - SCEb - Core - CEbSAb - CSAb - SAb
Patient p/w isolated elevation of [total anti-HBc (Core Ab)]
How should you manage this?
[repeat HBV serologies] –> obtain [[IgMCore] and LFT] to determine acuity of [window acute HBV]
_________________
S - SEC - SCEb - Core - CEbSAb - CSAb - SAb
What 2 laboratory values are the best diagnostic test for Hepatitis B?
S - SEC - SCEb - Core - CEbSAb - CSAB - SAb
[SAg and CoreIgM]
The Hepatitis A vaccine is recommended for which groups - 3
- Travelers going to countries where HepA is present
- Gay Men
- Chronic Liver Disease
Hepatitis A can cause SIGNIFICANT but benign TRANSAMINITIS so do not be alarmed by this
self limited to 1 month
What is the best diagnostic test for [osteomyelitis of the foot]?
_________________
Name the test used at bedside for [osteomyelitis of the foot], and why it is not the best test?
contrast MRI
_________________
[probe-to-bone testing] (usually done first and not sensitive…so if negative, still must use contrast MRI to r/o infxn)
Diabetic foot infections with osteomyelitis require ⬜ to determine microbial involvement
BONE BIOPSY WITH CULTURE
tx Conjunctivitis -8
⬜ is a rare complication of bacterial conjunctivitis and is managed with ⬜
_________________
How does this complication typically present? -3
Keratitis (inflammation of cornea) ; URGENT OPHTHALMOLOGY CONSULT FOR TX
_________________
[foreign body sensation] / photophobia / vision impairment
What is a [Hordeolum Stye]
bacterial infection of [eyelid sebaceous gland]
Why do pts with suspected Keratitis must receive URGENT OPHTHALMOLOGY CONSULT?
_________________
How is Keratitis diagnosed?
Keratitis can cause corneal scarring which ➜ blindness if untreated by optho

Health Care Personnel was recently exposed to Varicella Zoster Virus
management for special HCP (pregnant/immunocompro) who did NOT have VZV immunity prior to working?
[VZV IG (or antiviral tx if IG not available)]
________________
IG = ImmunoGlobulin
Health Care Personnel was recently exposed to Varicella Zoster Virus
________________
management for HCP who did NOT have VZV immunity prior to working?
________________
[Varicella Vaccine within 5d of exposure]
Health Care Personnel was recently exposed to Varicella Zoster Virus
List management for HCP immune to VZV prior to working?
________________
How do you prove their immunity? -2
NOTHING
________________
([hx of Varicella infection] or [hx of 2-dose Varicella Vaccine])
describe [postherpetic neuralgia]
________________
tx -4
persistent allodynia and pain > 4 months after resolution of acute [herpes Zoster shingles] rash
________________
[Gabapentin vs Pregablin vs TCA] –(if fail)–> Opioids
how is VZV transmitted? -2
_________________
Name hospital isolation rules for pts with [acute Zoster Shingles] -2
DIRECT CONTACT >> [active lesion aerosolization]
_________________
[localized single Zoster = [lesion coverage + standard precautions]
[DISSEMINATED ZOSTER > 1 DERMATOME = CONTACT AND AIRBORNE + standard precautions]
_________________
apply this until lesions are crusted over
How long are pts with acute [herpes Zoster Shingles] contagious?
________________
how is VZV transmitted? -2
from the onset of lesions UNTIL LESIONS HAVE COMPLETELY CRUSTED OVER
________________
DIRECT CONTACT >> [active lesion aerosolization]
In Hospital: Contact and Airborne precautions. Home: keep lesions covered until completely crusted over!
How is Viral Conjunctivitis spread? -2
EYE DISCHARGE directly
Contaminated Surfaces
SIADH can range from mild, SEVERE or Euvolemia
What are the s/s of SEVERE SIADH?-2
Tx?
SEVERE SIADH = SEIZURES / COMA
________________
SEVERE SIADH (TX): [3% Hypertonic Saline]
SIADH can range from mild, SEVERE or Euvolemia
What are the s/s of mild SIADH?-2
Tx?
mild SIADH = nausea / forgetful
________________
mild SIADH: [Fluid restriction +/- salt tablets]
SEVERE SIADH: [3% Hypertonic Saline]
SIADH can range from mild, SEVERE or Euvolemia
What are the causes of SIADH -5
What are the causes of Acute Cervicitis? -5
4 major signs of Acute Cervicitis?
[T or F]
Crusted over eyes in the morning indicates patient is contagious with viral conjunctivitis
FALSE
(only EYE DISCHARGE and contaminated surfaces transmit viral conjunctivitis)

________________
how do you differentiate it from lipoma?
Desmoid tumor= slow but locally aggressive benign neoplasm with high recurrence rate (tx = radiation if asx // surgery if sx)
