Background: Historically, the degloved finger with the total loss of nail and skin had been resurfaced with an expanded great toe wrap-around flap transfer for better outcomes. The purpose of this study aims to present our experience with a related modified design, with total preservation of a weight-bearing plantar skin.

Method: From April 2016 to September 2019, nine fingers (5 index and 4 middle fingers) in nine cases, with skin loss to the base of the proximal phalangeal or metacarpophalangeal (MCP) joint level, were reconstructed with combined great toe dorsal nail-skin flap and medial plantar artery perforator (MPAP) flap.

Objective: To investigate the effectiveness of the wrap-around great toe flap combined with medial plantar artery perforator flap (MPAP) for repairing the completely degloved fingers.

Methods: Between February 2018 and December 2019, 12 patients with the completely degloved fingers caused by machine strangulation were admitted. There were 9 males and 3 females with a median age of 32 years (range, 18-42 years). Read More

The exploration and development of coordination nanocages can provide an approach to control chemical reactions beyond the bounds of the flask, which has aroused great interest due to their significant applications in the field of molecular recognition, supramolecular catalysis, and molecular self-assembly. Herein, we take the advantage of a semirigid and nonsymmetric bridging ligand (H) with rich metal-chelating sites to construct an unusual and discrete 3d-4f metallacage, [ZnEr(H)(NO)Cl(HO)]·NO·CHOH·HO (). The 3d-4f cage possesses a quadruple-stranded structure, and all of the ligands wrap around an open spherical cavity within the core. Read More

Stromal-epithelial interactions are critical to the morphogenesis, differentiation, and homeostasis of the prostate, but the molecular identity and anatomy of discrete stromal cell types is poorly understood. Using single-cell RNA sequencing, we identified and validated the in situ localization of three smooth muscle subtypes (prostate smooth muscle, pericytes, and vascular smooth muscle) and two novel fibroblast subtypes in human prostate. Peri-epithelial fibroblasts (APOD+) wrap around epithelial structures, whereas interstitial fibroblasts (C7+) are interspersed in extracellular matrix. Read More

Microsurgery 2021 Sep 4;41(6):543-549. Epub 2021 Jun 4.

Department of Plastic Reconstructive Surgery, Kansai Electric Power Hospital, 2-1-7 Fukushima, Fukushima-ku, Osaka, Japan.

Purpose: Because the subcutaneous tissue of the great toe is thicker than that of the finger, the reconstructed finger tends to have bulging pulp when reconstructing with wrap-around flap (WAF) surgery. Secondary pulp plasty and thinning of the WAF are used to solve this cosmetic problem. This study aimed to examine the effect of these surgical techniques on sensation. Read More
