Background: Hand wounds are frequent in children (31% of hand injuries) and one possible mechanism responsible for profound laceration is metal fences while climbing. These injuries usually require a surgical look to explore soft-tissue damages, but the literature is poor regarding surgical findings and outcomes after this kind of traumatism. The aim of the study was therefore to report a consecutive series of hand and finger wounds caused by metal fences in children, focusing on surgical findings and potential complications.
Methods: All consecutive hand or finger deep wounds caused by metal fences treated between January 2013 and December 2018 were retrospectively reviewed. Inclusion criteria were age below 18 years and a minimum follow-up of 2 years. Complications and surgical revisions were analyzed.
Results: A total of 1265 patients were operated for hand or finger deep wounds during the study period, among which 74 were caused by metal fences. The mean age at surgery was 11.3±0.4 years, and the majority of patients were men (80%). Associated injuries were found in 55.4% of the patients including nerves (n=29) or tendons sections/disinsertion (n=6), and sheath (n=16) and pulleys (n=6) tearing. At a mean follow-up of 2.6±0.2 years, 12% of the patients required revision surgery for an irreducible flexion contracture secondary to a contractile scar and consisted of complete scar excision and zigzag flap. Additional tenoarthrolysis was required during the procedure, for 6 patients because of a persisting flexion contracture after excision.
Conclusions: Metal fences surgical palmar wounds in children are impressive lesions by their extended skin damages. Serious associated lesions (collateral pedicle or flexor tendons) were found in 1 case of 3. However, these injuries are not benign and should be carefully monitored clinically during the first postoperative month to look for potential contractile scars that can require revision.
Level Of Evidence: Level IV-retrospective cohort study.

ConspectusFor chemical reactions with complex pathways, it is extremely difficult to adjust the catalytic performance. The previous strategies on this issue mainly focused on modifying the fine structures of the catalysts, including optimization of the geometric/electronic structure of the metal nanoparticles (NPs), regulation of the chemical composition/morphology of the supports, and/or adjustment of the metal-support interactions to modulate the reaction kinetics on the catalyst surface. Although significant advances have been achieved, the catalytic performance is still unsatisfactory.

Suzuki-Miyaura coupling (SMC), a crucial C-C cross-coupling reaction, is still associated with challenges such as high synthetic costs, intricate work-ups, and contamination with homogeneous metal catalysts. Research intensely focuses on strategies to convert homogeneous soluble metal catalysts into insoluble powder solids, promoting heterogeneous catalysis for easy recovery and reuse as well as for exploring greener reaction protocols. Metal-Organic Frameworks (MOFs), recognized for their high surface area, porosity, and presence of transition metals, are increasingly studied for developing heterogeneous SMC.

Article Synopsis
- The study examines two cases of bovine osteomyelitis in cattle related to injury from a metal fence, focusing on long-term treatment effectiveness.
- In Case 1, a heifer underwent surgical treatment with antibiotics, achieving recovery in 130 days, while Case 2, a calf, received non-surgical treatment with antibiotics and healed in 155 days.
- The findings suggest that long-term wound care and surgical intervention are effective strategies for treating bovine osteomyelitis in cattle.
Construction of Vine-Inspired Antimicrobial Filter with Multiscale 3D Nanonetwork for High-Efficiency Air Filtration.

Enhancing the antimicrobial activity of high-efficiency particulate air (HEPA) filters while maintaining filtration efficiency and pressure drop is currently an urgent issue for preventing the spread of pathogenic microorganisms. Herein, inspired by vines which can enwind fences to fix as well as decorate them, a flexible antimicrobial chitin nanofiber (ChNF@CuO) was fabricated and loaded onto the rigid glass fiber (GF) skeleton of a HEPA filter. Through the physical interaction, ChNF@CuO was spontaneously enwound on GF, and ChNF@CuO itself interweaved to form a new nanonetwork between the GF skeleton.

An Fe(III)-carbonato six-coordinate picket fence porphyrin complex with the formula [K(2,2,2-crypt)][Fe(TpivPP)(CO)]·CHCl·3HO () has been synthesized and characterized by UV-Vis and FT-IR spectra. The structure of (carbonato)(α,α,α,α-tetrakis(-pivalamidophenyl)porphinato)ferrate(III) was also established by XRD. The iron atom is hexa-coordinated by the four nitrogen atoms of the pyrrol rings and the two oxygen atoms of the CO group.
