Retrograde dorsalis pedis angiosomal flow compromised by small puncture wound leading to transmetatarsal amputation.

Foot (Edinb) 2019 Feb 14;39:60-67. Epub 2019 Feb 14.

Foot and Ankle Surgery Resident, Dept. of Orthopedics, John Peter Smith Hospital, 1500 S. Main Street, Fort Worth, TX, 76104, United States.

Pedal puncture wounds can precipitate a variety of complications, often resulting from a delay in treatment. Although the risk of infection predominates, direct vascular insult and subsequent ischemia is a lesser reported complication of these injuries. Consequently, this may have morbid results, especially on a background of pre-existing peripheral vascular disease. Read More

Skin Changes During Ageing.

Subcell Biochem 2019;91:249-280

Faculties of Medicine and Pharmacy, Department of Physiology, University of Limoges, Myelin Maintenance and Peripheral Neuropathies (EA 6309), Limoges, France.

The skin provides the primary protection for the body against external injuries and is essential in the maintenance of general homeostasis. During ageing, resident cells become senescent and the extracellular matrix, mainly in the dermis, is progressively damaged affecting the normal organization of the skin and its capacity for repair. In parallel, extrinsic factors such as ultraviolet irradiation, pollution, and intrinsic factors such as diabetes or vascular disease can further accelerate this phenomenon. Read More

Vasc Health Risk Manag 2018 28;14:247-251. Epub 2018 Sep 28.

Immunology Research Center, Inflammation and Inflammatory Diseases Division, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran,

Background: The possible role of infectious pathogens in the development of thromboangiitis obliterans (TAO) was considered soon after the disease was first described. However, it is not yet known whether infectious pathogens induce thrombotic vasculitis or if they cause a type of autoimmune disease. To investigate whether TAO relapses are more likely due to reinfection or autoimmune flare, the serum levels of toll-like receptor (sTLR) 4, sTLR2, C-reactive protein (CRP), and neopterin were evaluated in TAO patients during both the acute and quiescent phases of the disease as well as in a gender-, age-, and smoking habit-matched control group.

Distinct roles of angiotensin receptors in autonomic dysreflexia following high-level spinal cord injury in mice.

Exp Neurol 2019 01 10;311:173-181. Epub 2018 Oct 10.

Max Delbrück Center for Molecular Medicine (MDC) in the Helmholtz Association, Berlin, Germany; Berlin Institute of Health (BIH), Berlin, Germany; German Center for Cardiovascular Research (DZHK), Partner Site Berlin, Berlin, Germany; Institute for Biology, University of Lübeck, Lübeck, Germany.

Autonomic dysreflexia (AD), a syndrome caused by loss of supraspinal control over sympathetic activity and amplified vascular reflex upon sensory stimuli below injury level, is a major health problem in high-level spinal cord injury (SCI). After supraspinal sympathetic control of the vasculature below the lesion is lost, the renin-angiotensin system (RAS) is thought to be involved in AD by regulating blood pressure and vascular reactivity. In this study, we aimed to assess the role of different RAS receptors during AD following SCI. Read More

Surgical Management of Spasticity of the Elbow.

Hand Clin 2018 Nov 20;34(4):503-510. Epub 2018 Aug 20.

Department of Orthopaedic Surgery, Nicklaus Children's Hospital, 3100 Southwest 62nd Avenue, Miami, FL 33155, USA.

A spastic limb refers to one with increased tone. This commonly results from an upper motor neuron injury, which, in turn, leads to disinhibition of reflex arcs. At the level of the elbow, affected individuals typically exhibit a flexion posture secondary to spastic contracture of the biceps, brachialis, and brachioradialis muscles. Read More

Vasodilator function is impaired in burn injury survivors.

Am J Physiol Regul Integr Comp Physiol 2018 Nov 26;315(5):R1054-R1060. Epub 2018 Sep 26.

University of Texas Southwestern Medical Center and Institute for Exercise and Environmental Medicine, Texas Health Presbyterian Hospital , Dallas, Texas.

The effect of severe burn injury on vascular health is unknown. We tested the hypothesis that, compared with nonburn control subjects, vasodilator function would be reduced and that pulse-wave velocity (a measure of arterial stiffness) would be increased in individuals with prior burn injuries, the extent of which would be associated with the magnitude of body surface area having sustained a severe burn. Pulse-wave velocity and macrovascular (flow-mediated dilation) and microvascular (reactive hyperemia) dilator functions were assessed in 14 nonburned control subjects and 32 age-matched subjects with well-healed burn injuries.

Wellman Center for Photomedicine, Massachusetts General Hospital, 40 Blossom St., Boston, Massachusetts, 02114, USA.

Severe peripheral nerve injuries often result in partial repair and lifelong disabilities in patients. New surgical techniques and better graft tissues are being studied to accelerate regeneration and improve functional recovery. Currently, limited tools are available to provide in vivo monitoring of changes in nerve physiology such as myelination and vascularization, and this has impeded the development of new therapeutic options.

Neurorehabil Neural Repair 2018 09;32(9):765-776

2 University of Maryland School of Medicine, Baltimore, MD, USA.

Peripheral nerve injury is a major clinical problem and often results in a poor functional recovery. Despite obvious clinical need, treatment strategies have been largely suboptimal. In the nervous system, exosomes, which are nanosized extracellular vesicles, play a critical role in mediating intercellular communication. Read More

Injury-induced perivascular niche supports alternative differentiation of adult rodent CNS progenitor cells.

Elife 2018 09 17;7. Epub 2018 Sep 17.

Laboratory of Molecular Neurobiology, Neurobiology Center, Nencki Institute of Experimental Biology, Polish Academy of Sciences, Warsaw, Poland.

Following CNS demyelination, oligodendrocyte progenitor cells (OPCs) are able to differentiate into either remyelinating oligodendrocytes (OLs) or remyelinating Schwann cells (SCs). However, the signals that determine which type of remyelinating cell is generated and the underlying mechanisms involved have not been identified. Here, we show that distinctive microenvironments created in discrete niches within demyelinated white matter determine fate decisions of adult OPCs. Read More

Infrared Thermographic Analysis of Surface Temperature of the Hands During Exposure to Normobaric Hypoxia.

High Alt Med Biol 2018 Dec 22;19(4):388-393. Epub 2018 Aug 22.

1 Warwick Medical School, University of Warwick , Coventry, United Kingdom .

Frostbite and other cold-related injuries commonly develop during prolonged exposure to the low environmental temperatures of polar and mountainous regions. Hypoxia is a potent sympathetic stimulus that causes vasoconstriction of the peripheral blood vessels, which may further compound the risk of developing a cold-related injury during high-altitude exposure. To investigate this, we utilized portable infrared thermographic technology to quantitatively measure changes in the surface temperature of the hands during exposure to increasing levels of normobaric hypoxia in a temperature-controlled high-altitude simulation.
