Does the Nail Bed Regenerate?

Background: The regenerative potential of the nail bed after trauma remains controversial.

Methods: We performed a retrospective review of 51 patients who underwent nail bed reconstruction with 2 techniques (direct flow island flap or a Tranquilli-Leali "Atasoy" flap) due to trauma involving the nail bed complex. These 2 flaps were used to support the loss of distal substance and to allow the regeneration of the nail bed.

First-line Treatment of Metastatic Renal Cell Carcinoma in the Immuno-oncology Era: Systematic Review and Network Meta-analysis.

Combination treatments with immuno-oncology (IO) agents and IO agents plus a vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI) have been approved for first-line treatment of patients with metastatic renal cell carcinoma (mRCC). No direct comparisons have been performed among these treatment options. We performed a systematic review and network meta-analysis to compare and rank the available regimens for first-line treatment in terms of survival benefit and efficacy.

Nerve conduits for treating peripheral nerve injuries: A systematic literature review.

Peripheral nerve injuries are a major public health problem. Nerve conduits have been developed in the recent years, although it is still not clear if they should replace nerve grafting and neurorrhaphy. This systematic review aims to gather evidence regarding the use of nerve conduits for peripheral nerve repair.
