It is often hereditary (autosomal dominant) and can be associated with a head tremor, but it is not associated with other neurologic symptoms. Open / Comment

2022-03-01 09:32:48 A 44-year-old man comes to the office due to hand tremors. The patient first noticed the tremor 2 years ago, and it has gradually worsened. He feels well most of the time, but his hands shake uncontrollably with activities such as pouring drinks or writing notes. The symptoms are most pronounced during stressful situations such as office meetings, and he keeps his hands tightly squeezed together or hidden below the table. He has had no arm stiffness, leg symptoms, or difficulty walking, but his wife has noticed that the patient occasionally keeps nodding his head while talking. Physical examination shows obvious tremors of outstretched hands that worsen during finger-nose testing. Open / Comment

2022-02-28 21:36:01 Educational objective: The blood-brain barrier is formed by tight junctions between nonfenestrated capillary endothelial cells that prevent the paracellular passage of fluid and solutes. This barrier only permits the passage of substances from the blood to the brain via transcellular movement across the endothelial plasma membrane, which is limited by diffusion or carrier-mediated transport.

2022-02-28 07:34:01 A 68-year-old man with a history of Parkinson disease is hospitalized for pneumonia and sepsis. The patient is treated with intravenous (IV) fluids and antibiotics. He is also started on an infusion of IV dopamine for hemodynamic support. Although the manifestations of Parkinson disease are attributed to dopaminergic neuron degeneration in the substantia nigra, IV dopamine does not improve this patient's Parkinson symptoms.
