1

Bechet syndrome triad

Recurrent oral aphous ulcers
Genital Ulcers
Uveitis

2

Aphthous ulcer suggest presence of?

Inflammatory bowel diseases, Bechet syndrome

3

2 precursor lesions of sq cell carcinoma of mouth

Leukoplakia
Erythroplakia and Hairy

4

How to differentiate Leukoplakia, thrush and hairy leukoplakia

Leukoplakia cannot be scraped away (thrush can)

Hairy leukoplakia is on LATERAL tongue and is hairy looking (think HIV and EBV)

5

3 organs affected by mumps

Bilateral parotids
Orchitis
Pancreatitis

Think Amylase for diagnosis

6

Pleomorphic adenoma components

Stroma (cartilage!) and epithelial tissue --> BIPHASIC

7

Cystic parotid tumor with lymphoid tissue and germinal centers in the parotid

Warthin tumor (recall smoking and men)

8

TE fistula presentation (4)

Vomiting and coughing with FIRST FEEDING
Abdominal distension
Polyhydramnios

9

Esophageal web presentation and complication

dysphagia for solid, SCCA

10

Zenker diverticulum layers

Mucosa and submucosa only (false diverticlum)

11

Zenker location, the mechanism

b/w upper esophageal sphincter and pharynx, motor dysfunction*

12

Painful hematemesis in bullemic or alcoholic/retching

Mallory Weiss

13

Mallory weiss defect

longitudinal of mucosa at Gastroesophageal junction

14

Acute pain, X Ray haziness in mediastinum w/ shoulder pain, no hematemesis, Cardiac enzymes- normal

Borhaave syndrome --> ruputred GE junction

15

Usually Painless and Massive hematemesis of venous blood

Ruptured esophageal varicies

16

Dysphagia for solids + liquids with halitosis

Achalasia

17

Achalasia underlying defect

No ganglion cells in myenteric plexus = no relaxation

18

Imaging findings in Achalasia

Dilated esophagus
Increased LES pressure

19

Infectious cause of achalasia

Trypanasoma cruzi

20

Hiatal hernia- Sliding- complications?

Cardia of stomach herniates into esophagus--> GERD

21

"bowel sounds in the lung fields" is characteristic of

Hiatal hernia

22

late complication of GERD

Ulceration w/ stricture or adenocarcinoma

23

specific cell changes that occur in Barrets Esophagus

Non Keratinized Stratified Squamous epithelium --> Non ciliated columnar epithelium w/ goblet cells

24

Adenocarcinoma of esophagus location

lower 1/3

25

3 major risk factors for Esophageal adenocarcinoma

GERD (Obesity, Hiatial Hernia, hypothyroidism)

26

Sq Cell carcinoma of esophagus location

Upper 2/3

27

non billous projectile vomiting several weeks after birth + abdominal mass

Pyloric stenosis

28

2 mechanisms by which NSAIDs cause gastritis

Decreased PGE2 = More acid, less mucus, less blood flow

29

Increased intracranial pressure causing ulcers is called

Cushing ulcer --> increased vagal stimulation = increased acid

30

erosion vs ulceration

erosion - epithelium only
ulceration = entire mucosa and beyond (cross MM)
