2023-01-20 20:45:05 Educational objective: Trigeminal neuralgia is characterized by recurrent severe pain usually along the V2 (maxillary) and V3 (mandibular) branches of the trigeminal nerve (CN V), often triggered by minor stimuli. This condition is usually treated with carbamazepine. Open / Comment

2023-01-20 08:44:01 A 52-year-old woman comes to the office due to a week of intermittent pain on the right side of the face. It is intense, sharp pain on the right cheek and lips that lasts several seconds and recurs several times a day. The patient is afraid to brush her teeth or to drink cold water as both trigger the pain. She has a history of hypertension, type 2 diabetes mellitus, and seasonal allergies. She does not use tobacco, alcohol, or illicit drugs. Temperature is 36.9 C (98.4 F), blood pressure is 136/84 mm Hg, and pulse is 80/min. No rash or tenderness is present on palpation of the face.

2023-01-19 20:44:02 Educational objective: Myoclonus is characterized by sudden, involuntary muscle contraction or relaxation that results in movement of limbs or joints. Posthypoxic myoclonus is often seen after cardiac arrest; the acute form (myoclonus status epilepticus [MSE]) occurs while patients are still unconscious and is characterized by generalized (often symmetric) myoclonus that involves the axial, limb, and facial muscles. Prolonged MSE is a marker of poor prognosis. Open / Comment

2023-01-19 08:42:01 A 68-year-old man with chronic obstructive pulmonary disease (COPD) experiences progressive dyspnea, wheezinq, and cough over several days despite using inhaled glucocorticoids and bronchodilators. His shortness of breath rapidly worsens and emergency medical services (EMS) is called. The patient becomes unresponsive prior to EMS arrival and is found to have pulseless electrical activity. Cardiopulmonary resuscitation is begun, and he is endotracheally intubated. The patient regains spontaneous circulation on arrival to the emergency department and is found to have a large pneumothorax and exacerbation of COPD. His other medical conditions include hypertension, type 2 diabetes mellitus, and Parkinson disease. A chest tube is inserted, and the patient is admitted to the intensive care unit for further management Over the next several days, his respiratory status gradually improves, but he remains unresponsive despite not receiving any sedation. The patient is also observed to have recurrent episodes of brief contractions of various muscle groups. Deep tendon reflexes are normal. Serum electrolytes are within normal limits. Open / Comment

2023-01-18 20:42:02 Educational objective: The diagnosis of myasthenia gravis can be supported with the bedside ice pack test. In this test, an ice pack is applied over the eyelids for several minutes, leading to an improvement in ptosis. Patients with positive test results should undergo confirmatory testing for acetylcholine receptor antibodies (highly specific). Open / Comment

2023-01-18 08:41:02 A 65-year-old man is being evaluated for new-onset ptosis. Earlier in the day, the patient underwent right total knee arthroplasty for advanced osteoarthritis with no operative complications. While in the postoperative recovery unit, he had difficulty opening his left eye and developed slurred speech. The patient has never had these symptoms, and his preoperative neurologic examination was unremarkable. He has no prior history of double vision, difficulty swallowing, or limb weakness. Medical history includes ischemic stroke with no residual deficits, type 2 diabetes mellitus, hypertension, and a 20-pack-year smoking history. Temperature is 36.7 C (98.1 F), blood pressure is 150/90 mm Hg, pulse is 92/min, and respirations are 12/min. Neurologic examination reveals bilateral ptosis, left greater than right Pupils are equal in size and reactive to light An ice pack is placed over the closed eyelids for 2 minutes, leading to improvement of the ptosis.
