Explantation of 10 kHz Spinal Cord Stimulation Devices: A Retrospective Review of 744 Patients Followed for at Least 12 Months.

Objectives: High-frequency 10 kHz spinal cord stimulation (10 kHz-SCS) has achieved analgesia superior to traditional SCS in a number of studies. However, there is concern regarding long-term outcomes of 10 kHz-SCS. Prior work has suggested that explant rates are higher with 10 kHz-SCS.

Periorbital ecchymoses during general anesthesia in a patient with primary amyloidosis: a harbinger for bleeding?

Primary amyloidosis is a result of proliferation of a population of plasma cells that leads to an increased secretion of monoclonal immunoglobulins (amyloid). Amyloid protein infiltrates increase capillary fragility. Such capillaries can burst, even after minor stress, resulting in periorbital hemorrhage.
