Ten Years' Experience with Diagnosis and Treatment of Non-Subungual Glomus Tumor in the Fingers.

Non-subungual glomus tumor in the fingers is very rare. To explore the insights gained from diagnosing and treating non-subungual glomus tumors in the finger, we collected 19 cases in the last ten years, which were only reported as isolated cases in the previous literature. This was a retrospective study of 19 surgical patients between May 2012 and January 2022 with preoperative MRI, ultrasound, and their final pathological diagnosis is glomus tumor, while the lesions were located not under the nail bed.

Regulating Schwann Cell Growth by Nanosecond Pulsed Electric Field for Peripheral Nerve Regeneration In Vitro.

Schwann cells (SCs) are myelinating cells of the peripheral nervous system, playing a crucial role in peripheral nerve regeneration. Nanosecond Pulse Electric Field (nsPEF) is an emerging method applicable in nerve electrical stimulation that has been demonstrated to be effective in stimulating cell proliferation and other biological processes. Aiming to assess whether SCs undergo significant changes under nsPEF and help explore the potential for new peripheral nerve regeneration methods, cultured RSC96 cells were subjected to nsPEF stimulation at 5 kV and 10 kV, followed by continued cultivation for 3-4 days.
