Q

treatment of gallstones

Q

retropharyngeal abscess

A

presents with neck pain, odynophagia, and fever following penetrating trauma to the posterior pharynx. This infection can drain into the superior mediastinum. -If it extends through the alar fascia, it can enter the “danger fascia” and transmit infection into the POSTERIOR mediastinum and result in acute nectrotizing mediastinitis

Q

persisting pneumo despite bilateral chest tube placement

A

think of tracheobronchial rupture secondary to blunt thoracic trauma. The right main bronchus is most commonly injured in these patients

Q

whistling noise post rhinoplasty, suggests what?

(think Me Myself and Irene)

A

septal perforation likely resulting from a septal hematoma

19
Q

treatment of pancreatic pseudocyst that is symptomatic

A
endoscopic drainage (these psuedocysts can release amylase into circulation)
-if the patient is asymptomatic, no treatment is needed
20
Q

heparin to use in end stage kidney disease pts

A

use: unfractionated heparin

do NOT use: LMWH (enoxaparin) and rivaroxaban

21
Q

complicated diverticulitis treatment

(you saw this)

A

CT guided percutaneous drainage of abscess

22
Q

acute mesenteric ischemia presentation

A

sudden onset severe, poorly localized mid-abdominal pain accompanied by nausea and vomiting

23
Q

acalculus cholycystitis occurs in what type of pts?

A

occurs in critically ill hospitalized patients. Pts have jaundice in addition to pain/mass in URQ

24
Q

retroperitoneal hematoma dx, presentation, tx

A

non-con abd pelvis CT

presents: as sudden hemodynamic instability and ipsilateral back pain

tx: supportive

25
Q

dx of suspected urethral injury

A

retrograde urethrogram (x-ray of lower GI tract with injection of radiopaque contrast in the urethra)

26
Q

acute bacterial parotidis

A

usually occurs in dehydrated post-op patients with crappy oral hygiene

27
Q

ALT >150 in regards to pancreas

A

95% PPV for gallstone pancreatitis

28
Q

tx of spontaneous pneumo in your tall athletic kiddo with no trauma

A
  1. If small (<2cm), give O2 and supportive
  2. If large, do small needle decompression
29
Q

torus palantinus

A

benign, hard immobile mass on the roof of the mouth

  • the thin epithelium tends to ulcerate and takes a long time to heal given poor vascular supply
  • surgery only indicated if symptomatic
30
Q

anterior cord syndrome is seen with what procedure and presents how?

A

seen in thoracic aortic aneurysm repair

The anterior spinal artery provides blood to the anterior 2/3 of the spinal cord including motor tracks and sensory tracks (spinothalamic)

  • The dorsal column is SPARED (vibration and proprioception)
  • Presents with bilateral flaccid paralysis with UMN signs

**ALSO seen in whiplash injuries in old people

31
Q

the two lobes of the parotid gland are separated by what?

A

the FACIAL nerve

32
Q

chronically wounded, burned, scarred skin predispose to what?

A

Squamous cell carcinoma

-If arise within a burn called a majorlin ulcer

33
Q

what pH is sodium bicarb indicated?

A

<7.2

34
Q

hypocalcemia pt presentation

A

initially nonspecific symptoms such as fatigue anxiety, depression

  • Involuntary contractions involving the lips, face, and extremities are seen when more severe
  • prolonged QT

*surgically this is common in post-thyroidectomy pts

35
Q

ejection fraction in hypovolemic shock

A

INCREASED

The left ventricle is decreased due to decreased filling volume tries to compensate by increasing ejection fraction

  • also see an increase in sympathetic nervous system resulting in an increase in total peripheral resistance and HR
  • presents with, hypotension, tachycardia, cold extremities, and evidence of poor organ perfusion (somnolence, unresponsiveness) and physical exam findings of hypovolemia (flat neck veins)
36
Q

nasopharyngeal carcinoma is associated with reactivation of what?

A

EBV

  • It is especially endemic in China
  • often presents with nasal congesion and epistaxis, HA, CN palsy (facial numbness) and/or serious otitis media
37
Q

Aflatoxin B1

A

mycotoxin that contaminates agricultural products and is associated with an increased risk of Hepatocellular Carcinoma

38
Q

Broken penis, what do ya do?

A
  • First, this is rupture of the corpus cavernosum due to traumatic tear in tunica albuginea
  • MUST do retrograde urethrogram and then take pt to OR for surgery
39
Q

acute adrenal insufficiency (adrenal crisis)

A
  • seen in acute adrenal hemorrhage or infarction or stressors such as surgery
  • presents as hypotension/shock, n/v, abd pain, weakness, fever
