1. A 37-year-old woman presents with a history of right-sided facial paralysis
and periauricular discomfort since she awoke this morning. She is afebrile. She
had a 'cold sore' 1 week prior to her symptoms, but this resolved without
complications. During her neurologic exam, she was discovered to have an
inability to raise her right eyebrow and close her right eye completely. She
also has drooping of the right corner of her mouth. The rest of her neurologic
exam is normal. There are no masses or rashes evident. She denies a history of
prior CVA or neurologic illnesses. She does not take any medications. What is
the most likely diagnosis?
Multiple sclerosis
Primary lateral sclerosis
Myasthenia gravis
Bell's Palsy
Trigeminal neuralgia
2. Describe the typical clinical presentation of cryptococcal meningitis in
individuals with HIV.
Patients usually have a sudden onset of paralysis.
Patients typically show only gastrointestinal symptoms.
Patients present with severe respiratory distress.
Patients often present with a combination of headache, fever, and
neck stiffness.
3. Describe the significance of excluding other causes of cognitive impairment
, when diagnosing AIDS dementia complex in HIV positive patients.
Excluding other causes is unnecessary as all cognitive impairments are
treated the same.
Excluding other causes helps to identify the most effective treatment
for HIV.
Excluding other causes ensures that the cognitive decline is
specifically due to AIDS dementia complex and not other
conditions.
Excluding other causes is only relevant in advanced stages of HIV.
4. A 37-year-old man fell from a ladder as he finished hanging the Christmas
lights on his house. The right side of his head hit the alley cement, and he lost
consciousness for about 1 minute; he woke up with a headache, but he had
no other complaints. A few hours later, the patient is brought to the
emergency room by his neighbor because of an intense headache,
confusion, and left hand hemiparesis. On examination, the patient has a
bruise located over the right temporal region, mydriasis, and right deviation
of the right eye, papilledema, and left extensor plantar response. An
emergency CT scan of the head without contrast reveals a lens-shaped
hyper-density under the right temporal bone with mass effect and edema.
What is the most likely diagnosis?
Subdural hematoma
Subarachnoid hemorrhage
Acute meningitis
Intracerebral parenchymal hemorrhage
Epidural hematoma
5. A 44-year-old man starts to notice that his eyelids are drooping. Some time
afterward, his jaw becomes weak. He has difficulty swallowing and
experiences weakness in his limbs. He is quite embarrassed when he eats
because he must use his hand to help support his jaw. His weakness gets
, progressively worse. Finally, he seeks medical attention. His physical
examination demonstrates the weakness in his limbs, but no sensory defects
are present. A Tensilon test is done and is positive. What is the most likely
underlying pathology of these symptoms?
Demyelination
Subacute combined degeneration of the spinal cord
Blockage of the sodium channels
Inhibition of acetylcholine release
Antibodies to the acetylcholine receptor
6. Which of the following is true about myasthenia gravis?
The "atropine test" is diagnostic when 0.5 mg of atropine is given
intravenously and the patient's symptoms improve within two minutes.
Weakness improves as the involved muscles are used repeatedly.
It typically presents as an ascending weakness of the peripheral
nervous system.
A myasthenic crisis involves an exacerbation of weakness,
especially of respiratory muscles, often necessitating intubation.
Cooling exacerbates the symptoms, and heat alleviates them.
7. Describe the significance of elevated CSF protein content in the diagnosis of
Guillain-Barré syndrome (GBS).
Elevated CSF protein content suggests a bacterial infection in the
central nervous system.
Elevated CSF protein content is a sign of normal CSF findings in GBS.
Elevated CSF protein content indicates a disruption of the blood-
CSF barrier, which is characteristic of GBS.
