CN V (trigeminal nerve) sensory deficit?,”CN V contains sensory fibers in its 3 branches; the V3 (mandibular) branch also contains motor fibers. The V1 (ophthalmic) branch carries sensory fibers to the scalp, forehead, upper eyelid, conjunctiva, cornea, nose, and frontal sinuses. Damage to the V1 branch causes corneal anesthesia. Common causes of CN V dysfunction include tumor, trauma

Myocardial infarction location based on coronary vessel involvement?,”RCA occlusion can cause acute inferior and posterior wall myocardial infarctions (MIs). Inferior wall MI presents with ST-segment elevations in the inferior leads (II, III, and aVF). ST-segment depression in leads V1 and V2 in this setting usually suggests a posterior wall MI. Inferior MI is also associated with hypotension, bradycardia

Lumbar spinal stenosis?,”SS is due to narrowing of the spinal canal, with resulting compression of lumbar nerve roots. The symptoms of SS are posture-dependent. Flexion of the spine causes widening of the spinal canal; extension causes narrowing of the canal. Therefore, the leg pain of lumbar SS is exacerbated by extension of the spine (standing, walking upright) and improved by flexion (sitting, leaning forward). This phenomenon is referred to as “”neurogenic claudication”” as the patient will experience lower-extremity pain with walking that may resemble vascular claudication. Diagnosis of SS is confirmed radiologically with MRI of the spine, and treatment may be conservative (eg, PT, home exercise program) or surgical (eg
