subthalamic nucleus
Where is the lesion?
pt presents with hemispatial neglect syndrome
right parietal lobe
where is the brain lesion if pt presents in coma?
Pons - specifically reticular activating system (RAS)
Where is the brain lesion if pt presents with poor repetition

(meaning patients can speak relatively well and have good auditory comprehension but cannot put parts of words together or conjure up words)
termed conduction aphasia, lesion of the arcuate fasciculus, in the white matter underlying the temporal–parietal junction; this lesion disconnects Wernicke's area from Broca's area.
where is the brain lesion?

The patient has difficulty naming even simple objects. Repetition is impaired, but comprehension of spoken language is normal. The patient is usually aware of the deficit and appropriately concerned about it.
Broca's aphasia caused by a lesion in the inferior frontal gyrus in the dominant hemisphere

Most lesions that involve Broca's area also involve the neighboring motor cortex. Patients are often hemiplegic, with the arm more affected than the leg. Broca's aphasia often occurs as a result of strokes, most commonly affecting the middle cerebral artery territory.
Where is the brain lesion?

Pt has fluent speech, but repetition and comprehension are impaired. Has difficulty naming objects and produces both literal paraphasias (eg, "wellow" instead of "yellow") and verbal paraphasias (eg, "mother" instead of "wife"). Neologisms (meaningless, nonsensical words) are used commonly and speech may be circumlocutory (ie, wordy but meaningless). Patient does not appear concerned about, or even aware of speech disorder.
Wernicke's aphasia: caused by a lesion in or near the superior temporal gyrus. Because this part of the cortex is not located adjacent to the motor cortex, there is usually no hemiplegia.

Wernicke's aphasia commonly occurs as a result of embolic strokes.
Where is the brain lesion?

When pt is asked to touch his or her nose with a finger, the arm exhibits tremor during movement, often more marked as the target is reached.
INTENTION TREMOR = occurs during activity.

results from a lesion affecting the superior cerebellar peduncle (or more generally, from cerebellar hemisphere)

(note: this form of tremor is sometimes mistaken for limb ataxia, but the latter has no rhythmic oscillatory component)
where is the brain lesion?

pt exhibits a tremor that occurs when the limb is at rest.
RESTING TREMOR - tremor apparent when arm is at rest, characteristic of Parkinson's disease

results from lesion to the Basal Ganglia

This tremor may appear as a "pill-rolling" maneuver—rhythmic, opposing circular movements of the thumb and index finger. There may be alternating flexion and extension of the fingers or hand, or alternating pronation and supination of the forearm.
Pt presents with hyperorality (a tendency to explore objects by placing them in the mouth together with the indiscriminate eating or chewing of objects and all kinds of food); hypersexuality, psychic blindness, or visual agnosia, in which objects are no longer recognized; and personality changes, usually with abnormal passivity or docility.

2) delay somewhere in the interventricular conduction system - either a interventricular conduction delay or bundle branch block

What is the immediate treatment for a patient with a pelvic fracture?
What are the classic signs of urethral injury? What study can be used to confirm this?
Look for blood at the urethral meatus, a high-riding “ballotable” prostate, or absence of palpable prostate
If signs of injury → retrograde cystourethrogram to r/o injury prior to Foley catheter placement
What is the classic sign for a bladder injury? What study can be used to confirm this?
Hematuria is most frequently seen in bladder injuries
A Retrograde cystourethrogram can be used to diagnose the bladder injury and determine if it is an intraperitoneal or extraperitoneal rupture
If extraperitoneal rupture → Foley catheter for 10 – 14days
If intraperitoneal ruptures → Urgent laparotomy for bladder repair
What antibiotic prophylaxis should be provided for rape victims? What other prophylatic measures should also be taken?
What is the next step in the evaluation of a male trauma patient with blood at his urethral meatus & a high riding prostate? What is contraindicated?
Next step: retrograde urethrogram
Contraindications: do NOT attempt to place a foley!
What should be done to evaluate an extremity trauma?
Full sensory & motor exam
What should you be looking for in a fetal ultrasound in the pregnant patient that has been involved in a MVA?
Placental abruption
Since bleeding between the fetus & mother is a concern in trauma, what actions should be taken once the patient and the fetus are stabilized?
Test mother’s Rh status
What criteria must be met before a pregnant trauma pt can be discharged from the hospital? (Hint: these are essentially the opposite of the symptoms found in placental abruption)
1. Contraction frequency ( < 1 every 10 min)
2. Normal fetal heart tracing
3. Absence of vaginal bleeding & abdominal pain
What antibiotics should be given in a case of sexual assault?
Ceftriaxone, Azithromycin, Metronidazole
What are some classic signs of physical abuse?
Multiple bruises, inconsistent/vague history
Burns/ bruises in shapes of objects
Rib, skull, long bone fractures
HYQ: What radiographic study is used to diagnose injury to the urethra?
Retrograde cystourethrogram
HYQ: Chest trauma + hypotension + JVD + distant heart sounds → what is the next step in the management of this patient?
Dx: Cardiac tamponade
Tx: Pericardiocentesis; pericardial window
HYQ: Chest trauma + hypotension + JVD + respiratory distress → what is the next step in the management of this pt?
Dx: Tension Pneumothorax
Next steps: needle decompression of the chest & placement of a chest tube
HYQ: What is the next step in the evaluation of penetrating injuries to the different zones of the neck?
Zone 1: 4 –Vessel arteriogram
Zone 2: surgical exploration
Zone 3: CT angiogram + triple endoscopy
HYQ: What is the next step in the evaluation of penetrating injuries to the different zones of the neck?
Zone 1: 4 –Vessel arteriogram
Zone 2: surgical exploration
Zone 3: CT angiogram + triple endoscopy
HYQ: What interventions are effective in the management of elevated intracranial pressure?
Elevate head of bed to 30°
Intubate/ hyperventilate temporarily
Decompressive craniectomy
What is the next step -

Pelvic fracture + DPL shows blood in the pelvis
Emergent laparotomy
What is the next step :
Pelvic fracture + DPL shows urine in the pelvis
Urgent laparotomy
What is the next step
Pelvic fracture + DPL shows nothing + hemodynamic instability
Angiography with possible embolization
What is the next step
Blunt abdominal trauma + unstable vital signs + FAST shows fluid in pelvis
Emergent Laparotomy
What is the next step
Blunt abdominal trauma + unstable vital signs + FAST shows no fluid in pelvis
Angiography with possible embolism
What is the next step
Blunt abdominal trauma + unstable vital signs + FAST inconclusive
What is the next step
Blunt abdominal trauma + stable vital signs
CT of abdomen & pelvis
What is the next step
Abdominal stab wound + hypotensive or signs of peritonitis
Emergent laparotomy
What additional studies can be performed in the case of a stable patient with an abdominal stab wound that penetrated the peritoneum?
Diagnostic laparotomy best
Upright CXR
Diagnostic Ultrasound
Contrast CT of the abdomen & pelvis
