Atrophic pseudarthrosis of humeral diaphyseal fractures: medico-legal implications and methodological analysis of the evaluation.

Acta Biomed 2022 Jul 1;93(3):e2022176. Epub 2022 Jul 1.

Trauma Unit and Emergency Department, IRCCS Galeazzi Orthopedics Institute, Milano, Italy.

Humeral shaft fractures account for 1- 3% of all fractures and about 20-27% of those involving the humerus. In the past they were often conservatively treated, with an acceptable consolidation rate. Open reduction and internal fixation (ORIF) is the best choice in polytrauma patients, in complex or pathological fractures and in those associated with vascular injuries. Read More

Perineural Capsaicin Treatment Inhibits Collateral Sprouting of Intact Cutaneous Nociceptive Afferents.

Biomedicines 2022 Jun 4;10(6). Epub 2022 Jun 4.

Department of Physiology, University of Szeged, Dóm tér 10, 6720 Szeged, Hungary.

Perineural treatment of peripheral nerves with capsaicin produces a long-lasting selective regional thermo- and chemo-analgesia and elimination of the neurogenic inflammatory response involving degeneration of nociceptive afferent fibers. In this study, we examined longitudinal changes in mustard oil-induced sensory neurogenic vasodilatation and plasma extravasation following perineural capsaicin treatment of the rat saphenous nerve utilizing scanning laser Doppler imaging and vascular labeling with colloidal silver. Capsaicin treatment resulted in a marked decrease in mustard oil-induced vasodilatation in the skin area served by the saphenous nerve. Read More

Incorporating Blood Flow in Nerve Injury and Regeneration Assessment.

Front Surg 2022 20;9:862478. Epub 2022 Apr 20.

Department of Neurosurgery, University of Utah, Salt Lake City, Utah, United States.

Peripheral nerve injury is a significant public health challenge, with limited treatment options and potential lifelong impact on function. More than just an intrinsic part of nerve anatomy, the vascular network of nerves impact regeneration, including perfusion for metabolic demands, appropriate signaling and growth factors, and structural scaffolding for Schwann cell and axonal migration. However, the established nerve injury classification paradigm proposed by Sydney Sunderland in 1951 is based solely on hierarchical disruption to gross anatomical nerve structures and lacks further information regarding the state of cellular, metabolic, or inflammatory processes that are critical in determining regenerative outcomes.

Immunomodulatory and regenerative effects of the full and fractioned adipose tissue derived stem cells secretome in spinal cord injury.

Exp Neurol 2022 05 20;351:113989. Epub 2022 Jan 20.

Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, Braga 4710-057, Portugal; ICVS/3B's PT Government Associate Laboratory, Braga/Guimarães, Portugal. Electronic address:

Adipose tissue derived stem cells (ASCs) are recognized to secret a myriad of molecules (secretome) know to modulate inflammatory response, promote axonal growth as well vascular remodeling and cellular survival. In previous works we have reported the benefit effects of ASCs transplanted to the injury site in a rat model of spinal cord injury (SCI). Emerging evidence have shown that the therapeutic actions of these cells are a consequence of their intense paracrine activity mediated by their secretome, which includes soluble bioactive molecules and vesicles.

In vitro modulation of Schwann cell behavior by VEGF and PDGF in an inflammatory environment.

Sci Rep 2022 01 13;12(1):662. Epub 2022 Jan 13.

Clem Jones Centre for Neurobiology and Stem Cell Research, Griffith University, Nathan, QLD, Australia.

Peripheral glial cell transplantation with Schwann cells (SCs) is a promising approach for treating spinal cord injury (SCI). However, improvements are needed and one avenue to enhance regenerative functional outcomes is to combine growth factors with cell transplantation. Vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) are neuroprotective, and a combination of these factors has improved outcomes in rat SCI models. Read More
