can get before migraine and other neurological stuff
12
etiology and tx of halitosis
80-90% in oral cavity
5-8% nasal passages
3% tonsils (tonsillioiths)
tx- tx underlying cause
clean posterior tongue
good dental hygiene
rinsing and DEEP gargling of mouth wash
chew gum
decrease alcohol and coffee intake
drink water
13
odynophagia
pain produced from swallowing
mouth pain
14
stomatitis
blanket term for inflammatory cone of mouth
Oral infections- HSV, VZV, HIV infection, Candida
Autoimmune- Bechets syndrome, Sicca syndrome
Recurrent aphthous stomatitis (RAS)--most common cause of mouth ulcers in North America
always r/o cancer for persistent or unusual lesions
15
stomatitis tx
Symptomatic relief:
Triamcinolone acetonide in Orabase gel (for inflammation)
Topical analgesics (OTC)
Oragel
Anbesol
Magic mouthwash
Antivirals- acyclovir (if a viral infxn)
Chemical cautery w/ silver nitrate or sulfuric acid
Severe: intralesional or oral cortisone
16
xerostomia
dry mouth
causes:
diuretics
Drugs w/ anticholinergic effects (antihistamine, tricyclic antidepressant)
autoimmune (sicca and sjogrens)
normal aging
17
xerostomia presentation and tx
pres: C/O oral dryness, burning of mouth, difficulty eating and swallowing, tongue irritation, painful ulcerations.
tx-Salivary stimulation with sugarless hard candies
Saliva substitutes
Sialogogues: pilocarpine or cevimeline
Meds that increase salivation
18
laryngitis
hoarsness and dysphonia
freq seen w/ URI
inflammation of vocal fold mucosa and larynx
actue sx3 weeks
19
most common cause of laryngitis
VIRAL
can be bacterial, vocal trauma, gerd, autoimmune, environmental factors, use of asthma inhalers
20
what is most important management for laryngitis
vocal cord rest
21
indications for indirect laryngoscopy
Hoarseness > 2 weeks
Odynophagia
Voice change
Dysphagia
Hemoptysis
Foreign body sensation
Contraindications:
Uncooperative pt, or one w/ a strong gag reflex
Compromised airway (croup or epiglotitis)
22
Polypoid corditis (Reinke’s edema)
Isolated edema of the mucosal edge of the vocal fold
Etiology
Usually due to smoking
Maybe hormonal changes
Menopause
Hypothyroidism
Allergy, vocal abuse or URI
Therapy
Vocal rest
Medical management of etiology
23
vocal nodules
Thickened areas on the vocal cord, bilaterally occurring at the junction of the anterior and middle thirds (analogous to a callus)
Usual cause: smoking, reflux, muscle tension dysphonia, vocal abuse
Treatment:
Adults: excision
Children: monitor (these frequently regress in adolescence)
24
vocal polyps
Usual cause: smoking, reflux, muscle tension dysphonia, vocal abuse
More common in men
Unilateral
Sessile or pedunculated lesion on the vocal fold
Tx: excision
25
how to tell difference between polyps and nodules
nodules are bilateral
polyps are unilateral
26
what is the primary laryngeal cancer
squamous cell
27
most common cause of pharyngitis
viral
Over treatment of acute pharyngitis represents one of the major causes of antibiotic abuse.
28
complications of strep
rheumatic fever
post strep glomerular nephritis
PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infections (group A strep)
29
fxs of GABHS
Unusual before 3 years of age and highest incidence of occurrence between 6-15 years of age (25-40% of pharyngitis cases)
More frequent in late winter and spring (Jan-Apr), uncommon in summer
Classic symptoms
Acute onset of discomfort/sore throat
Dysphagia- usually from odynophagia
Malaise
Headache
Absence of other URI symptoms (rhinorrhea, conjunctivitis, diarrhea or cough)
Occasionally abdominal pain and vomiting
Classic physical signs
Exudative pharyngeal erythema
Palatal petechiae
Tender anterior cervical adenopathy
Fever (>101F or 38.3C)
Absence of post-nasal drainage
30
Gold standard test for strep
throat culture
31
tx for GABHS
DOC- oral pcn for 10 days
if allergic to pcn- z pack
32
what does tonsillitis usually cause
bacterial infxn: (usually children 6-15)
GABHS
viral infxn (usually children less then 6)
33
indications for tonsillectomy
>6 episodes culture-confirmed GABHS pharyngitis in 1 year
3 or more infections of tonsils and/or adenoids in 1 year despite adequate therapy
Chronic or recurrent tonsillitis associated with GABHS carrier state unresponsive to beta-lactamase resistant antibiotics
Chronic tonsillitis affecting work/school
Others
34
vincent's agngina (trench mouth)
Pathophysiology
Acute inflammation and necrotizing ulceration of the pharyngeal tonsils
Usually caused by mixed bacterial-spirochetal infection
Symptoms: Severe throat pain, often radiating to the ears, halitosis, bad taste
Signs: Tonsil is covered by pseudomembrane formed from necrosis of the superficial layer of the mucous membrane
Treatment
Oral/parenteral penicillin
Vigorous oral hygiene
