25
otitis media with effusion (OME/EAR GLUE)
1 thick mucoid, gray/brown fluid 2 sterile, sticky, glue like 3 accumulates in middle ear of children following blocked Eustachian tube 4 Associated with conductive deafness with intermittent earache 5 Predisposes to acute suppurative otitis media 6 Tympanosclerosis: hyaline degernation of the eardrum mucosa associated with OME
26
What is the etiology of chronic suppurative otitis media?
persistent non-healing perforation of the tympanic membrane
27
What are the clinical manifestations of chronic suppurative otitis media?
- chronic earache and deafness | - persistent discharge from external auditory meatus
28
Most important primary disease of small bones of the middle ear
otosclerosis
29
meniere's disease
1 marked distention of the cochlear duct by excess fluid 2 vestibular membrane (of Reissner) (VM) buldges into Scala vestibuli m membrane ruptures with two fluids mixing??? (Slide 47 confusing)
30
Hearing Loss
sounds waves NOT to inner ear
31
etiology of hearing loss
``` 1 usually ear wax 2 otitis externa and otitis media 3 barotrauma 4 ear drum perforation 5 otosclerosis 6 congenital malformations ```
32
Sensorineural hearing loss
Damage to inner ear or nerve tracts to brain
33
Etiology of sensorineural hearing loss
``` 1 usually presbyacusis -degernative changes in cochlea -very common in elderly 2 excessive noise 3 ototoxic drugs=ASA, Aminoglycosides, etc. 4 Post infective= Rubella, Cytomegalovirus, Toxoplasmosis, Meningitis 5 Acoustic neuroma 6 Head Injury ```
34
Ear disease in Children temporary hearing loss
acute otitis media or OME
35
Permanent hearing loss in children
usually sensorineural
36
Angioedema
allergic and toxic damage | 1 type I hypersensitivity; may be life-threatening
37
Allergic and toxic damage of the larynx
1 angioedema 2 acute toxic laryngitis 3 chronic laryngitis
38
Singer's nodules
1 Benign Thickenings, nodules, and polyps 2 smooth, round, minute fibrous nodules 3 junction of anterior one third and posterior two thirds of the vocal cord
39
Laryngeal Carcinoma usually occurs in
male, cigarette smokers, >40 yrs old
40
Sites of laryngeal Carcinoma
1 glottis= most common; best prognosis 2 Supraglottis= more often mets. since more lymphatics 3 subglottis= rarest; poor prognosis with late onset of symptoms
41
Some laryngeal carcinoma preceded by epithelial dysplasia
most are well-differentiated squamous cell carcinoma
42
Verrucous carcinoma variant
1 pathology of the larynx 2 affects one or both true vocal cords 3 locally destructive 4 metastasis is rare unless irradiation treatment
43
3 characteristic locations of esophageal diverticula
1 *Zenker Diverticulum = immediately above the upper esophageal spincter 2 near the midpoint of the esophagus 3 epiphrenic diverticulum= immediately above the lower esophageal spincter
44
What causes Achalasia?
loss of ganglion cells of the myenteric plexus (muscular)
45
Achalasia usually occurs in
middle aged adults
46
What is a lack of coordinated muscle contraction (peristalsis) and constant contraction of the loewr esophageal spincter. Dilation of the esophagus, difficult swallowing and retention of food bolus?
achalasia
47
Megaesophagus slowly evolves. | Predisposes to esophageal carcinoma
achalasia
48
What increases width of esophagus except distal spastic segment?
achalasia
49
Esophageal Varices
Esophageal submucosal venous channels enormously dilated secondary to portal hypertension (e.g. chronic liver disease, cirrhosis)
50
What can protrude into the esophagus's lumen?
Esophageal varices
51
If this ruptures or overlying mucosa ulcerates, then torrential hemorrhage into esophagus and stomach with hematemesis leads to exanguination
esophageal varices
52
Mallory-Weiss Tear (laceration)
1 lower esophagus 2 following vomitting with full stomach- severe retching 3 typically seen in alcoholism
53
hiatal hernia
upper part of stomach moves through the diaphragmatic esophageal hiatus into the thoracic cavity
54
symptoms of hiatal hernia
reflux, esophagitis, peptic ulcers in intrathoracic stomach and lower esophagus
55
what is an important complication of hiatal hernia?
esophagitis
56
two types of hiatal hernia
sliding and paraesophageal (rolling)
57
Gastroesophageal reflux
most common clinical abnormality of the esophagus
58
What leads to substernal pain (heartburn)
reflux of gastric acid contents into esophagus
59
Predisposing factors of Gastroesophageal reflux
1 increase abdominal pressure (overeating, pregnancy, recumbent position) 2 lower esophageal spincter lax or incompetent ( hiatal hernia, excessive smoking, and alcohol ingestion , scleroderma)
60
3 complications of GERD
esophagitis, erosive esophagitis, esophageal stricture
61
Gastroesophageal reflux complications
1 reflux-acute inflammation (Esophagitis) 2 Peptic ulceration (Erosive): lower esophagus, small ulcers 3 stricture- lower esophagus, progressive fibrosis of ulceration 4 barrett esophagus
62
barrett esophagus
persistent reflux results in columnar metaplasia of the lower esophageal squamous epithelial mucosa to glandular tall columnar epithelium and epithelial dysplasia. Eventually, adenocarcinoma may (3-10%) develop so monitor patients with endoscopy and biopsy
63
What does Adenocarcinoma (malignant esophageal tumor) most often arise from?
aberrant (ectopic) gastric mucosa or Barrett Esophagus
64
Where does Adenocarcinoma arise most frequently?
lower one third of esophagus
65
Clinical Squamous Cell Carcinoma
``` 1 alcohol and tobacco use 2 seen more in men 3 affects loewr and middle thirds 4 dysplastic epithelium may precede 5 dysphagia occurs when tumor becomes large ```
66
treatment of squamous sell carcinoma
surgery or irradiation
67
Prognosis of Squamous cell carcinoma?
regional lymph node involvemnet early and common | -survival rate is POOR with 5 yr. survival
68
Plummer Vinson Syndrome
1 severe iron deficiency anemia 2 middle aged and elderly women 3 more often Scandinavian origin 4 Squamous cell carcinoma at a rare esophageal site: posterior -cricoid area (upper 1/3)
