Exam 1 Flashcards
how to tell leukoplakia from candidiasis
leukoplakia doesn’t debride easily
what to do about leukoplakia
biopsy if persistent
what percentage of leukoplakia/erythroplakia is malignant or premalignant
10%
most common site of oral cancer
lower lip
pain with oral cancer
painless until metastasis
risk factors for oral cancer
tobacco, actinic radiation, syphilis
signs of dysphagia
weight loss, avoiding certain foods
signs suggestive of oropharyngeal dysphagia
aspiration, nasal regurgitation, abnormal neuro exam
what to do if signs suggestive of oropharyngeal dysphagia with warning signs of malignancy
refer to ENT for laryngoscopic eval, FEES
what to do if signs suggestive of oropharyngeal dysphagia without warning signs of malignancy
refer for clinical swallow eval +/- modified barium swallow
voluntary phase of swallowing
oral phase
3 essential functions of oral cavity
production of speech, initiation of alimentation, host protection
what cells in salivary glands produce saliva and do they atrophy with aging
acinar cells, no
most common causes of xerostomia
iatrogenic, sjogrens, oral infections, gland obstructions, oral cancer
how many over 65 are adentulous
1/3
what medications can cause dry mouth
anticholinergics, antihistamines, antidepressants, diuretics, CCB
what factors contribute to teeth loss
xerostomia, lack of care, bone loss, caries, peridontal disease, poor diet
causes of angular chelitis
immune dysfunction, poor nutrition, mouth breathing, dry mouth
what malignancy does leukoplakia usually represent
SCC
is atrophic glossitis painful
no
causes of atrophic glossitis
deficiencies (B12, iron, vitamin E), medication reaction, autoimmune
classic presentation of oropharyngeal dysphagia
history of stroke or oral cavity problems, sensation of choking immediately after swallowing, with associated respiratory ssx
classic presentation of esophageal dysphagia
history of motility/neuromuscular disorder or mechanical esophageal problem with sensation of chest pain several seconds after swallowing and associated copious salivation
what does difficulty swallowing solid foods suggest
obstructive problem
what does difficulty swallowing liquids suggest
neurologic problem
sequelae of dysphagia
aspiration, pain, dehydration, malnutrition, increased cancer risk, need supervision/special diet/increased time to eat
warning sign of laryngeal cancer
persistent hoarse voice non-responsive to PPI or allergy medications
location of SCC of esophagus
mid esophagus
location of adenocarcinoma of esophagus
distal esophagus
what is Zenker’s diverticulum
extrusion of esophageal mucosa between weak muscle fibers in the posterior hypopharynx
Zenker’s diverticulum presentation
transient dysphagia with aspiration, gurgling, neck mass, regurgitation, esophageal obstruction
Zenker’s diverticulum diagnosis
barium examination
Zenker’s diverticulum complications
intubation during endoscopy/NGT, bleeding
Zenker’s diverticulum treatment
consider surgical closure if symptomatic
what to do if hx of PUD but cannot stop NSAID/ASA
consider misoprostol
duration of treatment for PPI in gastritis/PUD
minimum of 8 weeks
gold standard for diagnosis and confirmed tx of gastritis/PUD
upper endoscopy
most common causes of gastritis
H Pylori (70%), viral infections, irritants (NSAIDs, ASA)
what processes are increased in the normal aging of the stomach
contact time with irritants (NSAIDs), prevalence of H Pylori, pernicious anemia, cancers
what processes are decreased in the normal aging of the stomach
clearance of liquids, sensory neuron function, mucosal blood flow, acid/pepsin/fluid secretion, cytoprotective factors
infectious causes of esophagitis
candida, H pylori, chlamydia/gonorrhea
chemical causes of esophagitis
acid reflux, caustic material
diagnosis of esophagitis
EGD
barrett’s pathophys
abnormal columnar epithelium replaces stratified squamous epithelium in distal esophagus
barrett’s sequelae
predisposes to adenocarcinoma
barrett’s ssx
usually painless
esophageal cancer presentation
progressive obstruction, dysphagia, weight loss, GI bleeds, persistent GERD
esophageal cancer risk factors
white males, obesity, tobacco, ETOH
esophageal cancer prognosis
generally poor (usually found in later stages)
NSAIDs typically cause ulcers in what location
gastric, may also be duodenal
is acute or chronic NSAID use more of a risk factor for gastritis
acute
pathophys of NSAID associated gastritis
COX-1 inhibition leads to decreased mucosal defense and inhibition of thromboxane A2 leading to reduced platelet function and risk of bleeding
gastritis common but atypical presentation
vague, low-intensity abdominal pain
GERD symptoms more common in elderly
vomiting, anorexia, belching, laryngitis, postprandial fullness, dysphagia, respiratory ssx
