Q

what is the vestibular system?

A

center of balance. otoliths in the SemiCircular canals move and bend hair cells to create electrical signals

Q

what is mucociliary clearance?

A

the way by which the sinuses maintain a sterile enviornment. Infection is secondary to impaired mucociliary clearance

Q

what is important about head and neck lymphatics from a clinical standpoint?

A

you need to think about what is going on under the surface. Concern if they are enlarged… where do places typically drain to? AKA Where does the inflamed lymph get drainage from?

A

bacterial: S. pneumo > H.Flu> M. Cat

Q

Txt of URIs : abx?

A

since >90% viral : NO Abx

  • maybe bacterial IF symptoms not improving >7days
  • only consider Abx <7days if suspected Strep

Q

tonsils and adenoids are what kind of lymph tissue? what do they secrete?

A

secondary- (there are lots of backups to the immune system)- so if you remove them its ok.
secrete topical IgA
IgG IgM into the blood

Q

what is herpangina?

A

coxsackievirus A

  • fever, sore throat, rash/ulcers on palate
  • -small vesicles w/ red base that BECOME ulcers
  • -severe pain
    txt: stomatitis cocktail (didn’t say in class… but it is benadryl liquid and maddox swish)
21
Q

pharyngitis- how does it present? what is the most likely cause and associated symptoms w/ this cause (symp not super important)?

A

red lateral walls or cobblestoned posteriorly

-90% cases are viral w/ symptoms runny nose, cough, conjunctivitis and diarrhea

22
Q

2 non-infectious causes of pharyngitis.. how they present, good to know but not imperative

A 
snoring= red uvula
larnygeal acid reflux= 
-chronic/recurrent pharyngitis/laryngitis 
-cough @ night 
-globus sensation in throat
23
Q

4 symptoms of tonsillitis

A
  1. odynophagia (pain w/ swallowing)
  2. dysphagia (difficulty swallowing)
  3. fever
  4. enlarged, tender lymph nodes in upper neck w/ possible exudate/tonsilloliths (stones from hardened pus- from bacteria).
    * “cervical adenopathy” =lymph nodes disease
24
Q

complications if tonsillitis is untreated

A

missed school/work

  • dehydration
  • abscess (peritonsillar or deep neck)
  • systemic complications (w/ strep)
25
Q

3 causes of tonsillitis

A
  • viral: adenovirus, rhinovirus, flu, etc.
  • bacteria: usually w/ exudate (not diagnositc)
  • mono EBV: w/ exudate
26
Q

what organism is “strep”?

A

group A beta-hemolytic streptococcus

other strep species can cause infection though

27
Q

what is chronic strep caused by?

A

group A strep, actinomyces (another type of bacteria)

28
Q

3 rare causes of bacterial tonsillitis

A

gonorrhea, clamydia, diptheria

29
Q

Dx of strep

A

sudden onset sore throat and fever, headache or nausea, swollen LNs, >3days sore throat
-rapid and culture

30
Q

3 types of group A txt

A
  1. PCN (amox)
  2. erythromycin if allergic to PCN
  3. 2nd line: amox/clav, cephalosporins, Clindamycin
31
Q

why treat strep if it self-limited and most would go away without abx?

A

local complications (peritonsillar or deep neck abscess, lymphadenitis)
systemic complications
contagious nature of it

32
Q
  • *what is a peritonsillar abscess?

* *what are 5 S&S to look for?

A

walled off collection of pus, outside the tonsil

  • unilateral
  • uvula medially deviated
  • bulging soft palate
  • trismus: inability to fully open jaw
  • dysphagia (hot potato voice)
33
Q

peritonsillar abscess txt

A

if < 3 days and mild: Abx w/ close f/u
if worse, needle aspiration, I&D,
maybe quinsy tonsillectomy (didnt expand on what this is)

34
Q

2 complications of peritonsillar abscess

A

spread (retropharyngeal or pharyngeal abscess)
–(deep throat to chest= high morbidity)
airway obstruction

35
Q

** 3 systemic complications of group A strep

A
  1. rheumatic fever (infects heart valves)
  2. scarlet fever- toxin produced, widespread rash, strawberry tongue
  3. glomerulonephritis: “coca cola” urine (strep antiBs depositting in uring)
36
Q

when to treat carriers of asymp. strep?

A

when theyre “ping-ponging” the infection among family

37
Q

what is diptheria?

A

RARE: vaccinate against
gray psuedomembrane (thick membrane covering back of throat)- can cause pain, difficulty breathing
systemic toxins- damage cardiac & neurologic

38
Q

txt for diptheria

A

erythromycin or PCN, antitoxin

39
Q

how long does mono last?

A

1-3+ months

40
Q

Dx of mono? how many also have strep?

A

symptoms >1 wk
tonsil, LN, posterior neck node enlargement
usually w/ tonsil exudate (thick, white, cant remove. confluated (continous- not spotty)
20-30% also have strep

41
Q

3 complications of mono

A
  1. splenomegaly
  2. hepatomegaly
  3. hepatosplenomegaly (2nd-4th week)
42
Q

3 ways to Dx mono

A
  1. monospot- rapid (only 60% pos. after 2 wks, 90% after 1 month)
  2. WBC elevated, lots of atypical lymphs (monocytes)
  3. mono panel- IgM (elevated in acute), IgG
43
Q

txt of mono

A
  1. Abx if coinfected (not amox, it will give a rash)

2. limits to activity (spleen)

44
Q

adenoid hypertrophy can cause?

A

they can block eustachian tubes and back of nose

-otitis media, mouth-breathing, chronic rhinorrhea, “nasal speech”

45
Q

tonsil hypertrophy can cause (especially in young kids)?

A

sleep apnea, bedwetting, hard to wake, behavior problems

46
Q

what is epiglottitis? does it present?

A

AIRWAY EMERGENCY
epiglottis and supraglottis (above vocal cords) swelling
presents:
1.sitting forward, drooling, can’t swallow
2.inspiratory stridor (noise)
3.fever, “toxic”

47
Q

what causes epiglottitis?

A

bacteria: Hemophilus influenza type B
(HIB vaccine against)
-risk: immunocompromised adults (alcoholics)

48
Q

**txt of epiglottitis

A

DO NOT use tongue depressor or scope

  • IV steroids, Abx, racemic epi
  • urgent anesthesia, ENT eval
  • may need intubation vs trach.
49
Q

torus palatini
