2022-08-30 21:15:43 Educational objective: Amaurosis fugax is characterized by painless, rapid, and transient monocular vision loss. The description of a curtain descending over the visual field is highly suggestive of this diagnosis. The most common etiology is retinal ischemia due to atherosclerotic emboli originating from the ipsilateral carotid artery; therefore, patients with vascular risk factors should receive a duplex ultrasound of the neck.

2022-08-30 08:14:01 A 75-year-old man comes to the office due to intermittent right eye vision loss. The patient reports 3 episodes over the past 2 months in which he suddenly experienced "a curtain falling over the right eye" for several minutes before it spontaneously resolved. He has no eye pain or discomfort, focal weakness, numbness, or headache. His medical history is significant for hypertension, hyperlipidemia, and osteoarthritis. He smoked cigarettes for 25 years before quitting at age 50. Blood pressure is 140/85 mm Hg and pulse is 7 4/min. Visual acuity, pupillary reflex, and funduscopic examinations are unremarkable. Further neurologic examination shows normal reflexes, motor strength, and sensation. Open / Comment

2022-08-29 21:14:01 Educational objective: Prosthetic valve thrombosis (PVT) is a potential complication of both mechanical and bioprosthetic valves. Patients can have a new murmur, heart failure due to valvular obstruction (stenosis) or regurgitation, or a thromboembolic event (eg, transient ischemic attack). Suspected PVT should be promptly evaluated with echocardiography. Open / Comment

2022-08-29 08:12:01 A 65-year-old woman comes to the emergency department for transient weakness. She experienced muscle weakness in her right arm and leg this morning that lasted approximately 20 minutes and has since resolved completely. The patient has had no headache, vision loss, or vomiting. She has never before had similar symptoms. Medical history is significant for hypertension and diet-controlled type 2 diabetes mellitus. The patient underwent mitral valve replacement with a bioprosthetic valve 5 years ago due to mitral valve endocarditis. She is a life-long nonsmoker. Blood pressure is 131/70 mm Hg, and pulse is 65/min and regular. Chest examination is unremarkable. Neurologic examination reveals no muscle weakness or sensory loss. ECG, complete blood count, and renal function are within normal limits. In addition to a neuroimaging study, Open / Comment

2022-08-28 21:12:03 Educational objective: Central vertigo presents with nonfatigable nystagmus, which cannot be suppressed by visual fixation. Head imaging should be performed to evaluate for cerebellar stroke or hemorrhage in patients who have persistent, new-onset central vertigo and vascular risk factors, neurologic signs/symptoms, or accompanying headache.
