Case ReportsUltrasound Imaging of Median Nerve Conduit in a Patient With Persistent Median Nerve Symptoms.
Peripheral nerve injury can be reconstructed using composite polymer nerve autografts, but the sonographic appearance of nerve wraps and conduits have not been well documented. This case report describes the sonographic findings in a 42-year-old woman with bilateral carpal tunnel syndrome status post nerve repair with a conduit. The cross-sectional area of the left median nerve was 24 mm at the carpal tunnel inlet and 5 mm at the forearm. ⋯ On review of the operative record and consultation with her surgeon (DR), it was determined that this represented the 2-mm nerve wrap used in the last surgery. Inclusion of these structures with the median nerve measured a total area of 52 mm at its maximum. In describing this image, we hope to lay the foundation for describing the sonographic appearance of peripheral nerve repair.

Electrographic and Clinical Natural History of Lateralized Periodic Discharges.
The long-term electrographic features of lateralized periodic discharges (LPD) and their impact on clinical management are unclear. The authors investigated routine EEGs (rEEG) to analyze the delayed natural history of LPDs, and studied the clinical care of these patients. ⋯ LPDs lead to markers of epileptogenicity in around 18% of patients. One-third of the study population developed epilepsy. rEEG findings were not found to be good indicators of epilepsy development in our small, retrospective study limited by its sampling bias. Indiscriminate, long-term use of AEDs in these patients is a concerning finding.
