A
  • fiber optic nasopharyngoscopy becoming procedure of choice!
- need:
light source
warmed mirror
gauze to wrap pts tongue
topical anesthetic can be used to prevent gagging
24
Q

Pt comes in complaining about voice being scratchy and coughing, has hoarse voice. Has nonproductive cough especially at night for past couple of weeks. No hemoptysis or night sweats or odynophagia, non-smoker, does take occasional tums for heart burn after he eats, has 3-5 drinks/week

  • nothing is remarkable on exam - you want to see down the throat - larynx - get?
  • then you see polyp on right vocal cord, what was most likely cause of this polyp?
  • pt education?
A
  • indirect laryngoscopy
  • most likely has GERD
  • acid is refluxing over vocal cords - forming polyps
  • educate pt: tell him not to eat large meals within 3 hrs of betime, elevate head of bed, don’t add pillows, no ETOH before bed, no acidic foods, use PPI
25
Q

  • self-limited condition
  • secondary to URI or acute vocal strain
28
Q

cause and Tx of chronic laryngitis?

Q

Laryngeal cancer -

A
  • primarily squamous cell
  • arises from mucosal surface of larynx
  • mets to regional lymph nodes
  • major risk factors: smoking and ETOH abuse
  • early lesions can appear initially as white (leukoplakic) plaques
  • 5 yr cure rate 90% for small, early stage lesions, cure rates halved if mets to lymph nodes
33
Q

Physiology of swallowing?

A
  • oral prepatory phase (CN 5, 7, 12): bolus processed by mastication, tongue impt to direct bolus to upper pharynx
  • pharyngeal phase (CN 5, 10, 11, 12): bolus advances into esophagus by pharyngeal peristalsis, cricopharyngeus muscle relaxes (makes up most of upper esophageal sphincter UES)
  • esophageal phase: peristaltic contractions in the body of the esophagus propel the bolus down, relaxation of LES allows the bolus to enter the stomach
34
Q

Disorders of the oral prepatory phase?

A
  • inadequate mastication
  • xerostomia
  • neuro disorders
  • disruption of oropharyngeal mucosa
35
Q

Disorders of the pharyngeal phase?

A
  • neuromuscular discoordination
  • obstructions within oropharynx
  • poor compliance of UES
36
Q

  • hx of neuro sxs
  • complain of wt loss, aspiration
  • dry mouth or eyes
37
Q

PE of pt with oropharyngeal dysphagia?

A
  • thorough HEENT exam
  • thorough neuro exam:
    CNs
    checking for muscle weakness
    ptosis (myasthenia gravis)
    signs of parkinsons (cogwheeling, shuffling)
38
Q

Dx tests for oropharyngeal dysphagia?

A
  • barium studies (give specific reason to radiologist)
  • fiberoptic endoscopic eval of swallowing
  • nasopharyngeal laryngoscopy
  • manometry: gives info mainly about UES
39
Q

35 yo male c/o of severe sore throat for 2 days, hurts to swallow and talk, he has some fever with one temp being 101.4. he denies congestion, cough, sneezing, or myalgias. He has been around his 4 yo nephew who goes to daycare. Non-smoker, healthy?
- Mouth exam and you see erythmatous tonsils
what next?
tx?

A
  • rapid strep and culture (if rapid strep negative and you think it is strep)
  • tx: amoxicillin or PCN
40
Q

Differential and abx use of acute pharyngitis?

A
  • over tx of acute pharyngitis represents one of major causes of abx abuse
  • diff:
    majority caused by viruses including influenza
    10% due to GAS
    others:
    HSV
    EBV (run monospot if rapid strep negative)
    HIV (primary)
    diptheria
41
Q

Centor criteria for IDing pts at high risk for having GAS?

A

criteria:

  • tonsillar exudates
  • tender anterior cervical adenopathy
  • fever by hx
  • absence of cough
  • pts with less than 3 centor criteria shouldn’t recieve either abx or dx testing
  • if adult has 3 or more of criteria then testing with rapid antigen detection test w/o backup throat culture for negative test
  • throat culture reserved for pts with neg RADT higher risk for more severe infections or when transmission of GAS is impt
42
Q

Testing - for acute pharyngitis?

A
  • obtain throat and nasopharyngeal specimens
  • RADT/ throat culture
  • monospot - rapid antigen test
  • influenza test
  • hx of HIV rfs consider primary HIV and test appropriately
43
Q

GAS tx?

A
  • PCN/amoxacillin: first line
  • can give PCN IM injection
  • if allergic cephalosporin or macrolide, if resistant: clindamycin
  • sulfonamides, fluoroquinolones, and tetracyclines shouldn’t be used b/c of high rates of resistance
  • should improve 2-3 days, if not f/u needed
  • some pts are pharyngeal carriers and there is usually another etiology for their condition

sx tx:
analgesics - NSAIDs, acetaminophen aspirin in adults (not in children)
-topical analgesics:
lozenges, sprays, fluids

44
Q

abx response - GAS?

A
  • w/in 24 hrs of abx therapy infectivity decreases by 80%
  • should be improved in terms of decreased pain and fever in 48 hrs
  • if not improving or worsening need to return to clinic
  • remind good hand washing to prevent spread of viruses and bacteria and not to share water bottles, utensils, or glasses
45
Q

Cause, presentation and signs of tonsillopharyngitis?

A
  • usually caused by GAS (other - EBV)
  • presentation:
    more severe sore throat, sometimes difficulty swallowing, fever

    enlarged, erythematous tonsils with exudate
    lymphadenopathy
  • hot potato voice: abscess
46
Q

Tests and tx goals for GAS tonsillopharyngitis?

A
  • same exam and tests as for pharyngitis - RADT, monospot, influenza swab, throat and nasopharngeal specimen
  • tx goals when GAS:
    reduce duration and severity of sxs - abscess, otitis media, sinusitis and meningitis
  • reduce nonsuppurative complications - acute rheumatic fever, glomerulonephritis (PSGN), ped autoimmune neuropsychiatric disorder (PANDAS) syndrome
  • reduce transmission to close contacts
47

peritonsilar cellulitis
mono
neoplasm
49
Q

Tests and tx options for peritonsillar abscess?

A
  • needle aspiration dx if purulent dc obtained, but if not -can’t rule it out

IND by ENT then start abx - sometimes IV
- occasionally these pts need immediate tonsillectomy

50
Q

Cause and spread of diphtheria?

  • findings?
  • Dx?
  • tx?
A
