Daniel S Marigold, Andrew J Chang, Kim Lajoie
The nervous system integrates visual input regarding obstacles with limb-based sensory feedback to allow an individual to safely negotiate the environment. This latter source can include cutaneous information from the foot, particularly in the event that limb trajectory is not sufficient and there is an unintended collision with the object. However, it is not clear the extent to which cutaneous reflexes are modified based on visual input. In this study, we first determined if phase-dependent modulation of these reflexes is present when stepping over an obstacle during overground walking...

PURPOSE: The aim of this study was to determine the reliability and validity of preoperative magnetic resonance imaging (MRI) scans for the detection of additional pathologies in patients with chronic ankle instability (CAI) compared to arthroscopic findings. METHODS: Preoperative MRI images of 30 patients were evaluated regarding articular and periarticular comorbidities and compared to intraoperative findings. The reliability of MRI was determined by calculating specificity, sensitivity, as well as positive and negative predictive values...

BACKGROUND: Reconstruction of soft-tissue defects in lower third of leg, ankle, and foot has been a challenge and reconstructive surgeons have been trying to innovate different flaps. To solve this issue, we propose a distally based sural artery peroneus flap (DBSPF) in which we include superficial portion of the peroneus brevis muscle and its blood supply with the peroneal artery distally. The aim of this study was to evaluate the functional outcome and its usefulness over conventional distal sural artery flap or other local options available...

Long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFA) are known to modulate a variety of immune cell functions. On occasion, this has led to diminished host resistance to certain viral and bacterial infections. Little is known about the impact of n-3 PUFA on host resistance to parasitic infection, however, based on results from a small study conducted more than two decades ago, we hypothesized that providing mice LC n-3 PUFA will diminish host resistance to Trypanosoma cruzi, the parasitic pathogen responsible for Chagas disease...

BACKGROUND: Hypothyroidism, one of the most common endocrine disorders, may induce neurological abnormalities at an early stage of the disease. AIM: The study was designed to assess the electrophysiological alterations of some selected variables of nerve conduction, brainstem auditory evoked potentials (BAEPs), and visual evoked potentials (VEPs) in hypothyroid patients. SUBJECTS AND METHODS: Sixty patients of newly diagnosed hypothyroidism and an equal number of age-matched controls were selected for the study...

The wake-promoting drug Modafinil has been used for many years for treatment of Narcolepsy and Excessive Daytime Sleepiness, due to a dopamine-related psychostimulant action. Recent studies have indicated that Modafinil prevents neuroinflammation in animal models. Thus, the aim of the present study was to evaluate the effect of Modafinil pretreatment in the Lipopolysaccharide (LPS)-induced sickness and depressive-like behaviors. Adult male C57BL/6J mice were pretreated with Vehicle or Modafinil (90mg/Kg) and, 30min later, received a single saline or LPS (2mg/Kg) administration, and were submitted to the open field and elevated plus maze test 2h later...

Synovial sarcoma of peripheral nerve (SSPN) is rare with only 26 cases reported in English. SSPN is often mistaken for a benign or malignant peripheral nerve sheath tumor (PNST) by clinicians and pathologists. Fifteen cases of SSPN were retrieved from the pathology files of 3 institutions. All tumors arose in a nerve based on imaging and/or operative findings and the diagnoses were histologically confirmed. Neuropathic symptoms predominated in 11 women and 4 men, 19- to 62-year-old (median, 39 years) with tumors involving the ulnar (5), median (3), peroneal (3) or sciatic (2) nerve, or the L4 or T1 nerve root (2)...

The effect of temperature on the degradation of anthocyanins in juçara and "Italia" grape extracts was determined between 50 and 90°C. For both species, thermal degradation followed a first-order kinetic model. The decimal reduction time decreased with increasing temperature, and dependence on the thermodegradable factor was lower at higher temperatures. The anthocyanins from juçara degraded more slowly than those extracted from "Italia" grapes. The activation enthalpy and free energy of inactivation indicated an endothermic reaction, not spontaneous degradation, whereas the activation entropy suggested that the transition state has less structural freedom than that of the reactants...

A 64-year-old man was scheduled to undergo endovascular aneurysm repair for an abdominal aortic aneurysm (AAA). Since preoperative computed tomography showed an AAA with common iliac artery and internal iliac artery (IIA) aneurysms, IIA embolization was scheduled. Embolization using a coil was supposed to be performed; however, the lateral sacral artery could not be selected. For this reason, IIA embolization using N-butyl-2-cyanoacrylate (NBCA) was undertaken. During embolization, the median sacral artery was unexpectedly embolized through the lateral sacral artery...

Recovery of lower-limb function after spinal cord injury (SCI) likely depends on transmission in the corticospinal pathway. Here, we examined whether paired corticospinal-motoneuronal stimulation (PCMS) changes transmission at spinal synapses of lower-limb motoneurons in humans with chronic incomplete SCI and aged-matched controls. We used 200 pairs of stimuli where corticospinal volleys evoked by transcranial magnetic stimulation (TMS) over the leg representation of the motor cortex were timed to arrive at corticospinal-motoneuronal synapses of the tibialis anterior (TA) muscle 2 ms before antidromic potentials evoked in motoneurons by electrical stimulation of the common peroneal nerve (PCMS+) or when antidromic potentials arrived 15 or 28 ms before corticospinal volleys (PCMS-) on separate days...

Tendon transfer surgeries are performed to restore lost motor function, but outcomes are variable, particularly those involving agonist-to-antagonist muscles. Here, we evaluated the possibility that lack of proprioceptive feedback reorganization and musculotendon adaptations could influence outcomes. Plantaris-to-tibialis anterior tendon transfer along with resection of the distal third of the tibialis anterior muscle belly was performed in eight cats. Four cats had concurrent transection of the deep peroneal nerve...

BACKGROUND: Malignant tumors in the proximal fibula are rare but life-threatening; however, biopsy is not routine due to the high risk of peroneal nerve injury. Our aim was to determine preoperative clinical indicators of malignancy. METHODS: Between 2004 and 2016, 52 consecutive patients with proximal fibular tumors were retrospectively reviewed. Details of the clinicopathological characteristics including age, gender, location of tumors, the presenting symptoms, the duration of symptoms, and pathological diagnosis were collected...

Background: Aneurysmal bone cyst is a solitary bone tumor, expansile and lytic most often seen in the second decade of life, more frequently in men than in women (2: 1). They can occur in any bone, most common in the metaphysis of the long bones of the lower limbs. Although it is a benign tumor formation, aneurysmal cysts may have an aggressive local evolution and can cause a significant decrease in bone strength. The pacient may present local pain, the appearance of local deformation due to a tumor mass or occurrence of pathological fractures...

Tendoscopy is an apparently safe and reliable procedure to manage some foot and ankle disorders.The most common foot and ankle tendoscopies are: Achilles; peroneal; and posterior tibial tendon.Tendoscopy may be used as an adjacent procedure to other techniques.Caution is recommended to avoid neurovascular injuries.Predominantly level IV and V studies are found in the literature, with no level I studies still available.There are many promising and evolving endoscopic techniques for tendinopathies around the foot and ankle, but studies of higher levels of evidence are needed to strongly recommend these procedures...

Traumatic knee dislocation is a complex ligamentous injury that may be associated with simultaneous vascular and neurological injury.Although orthopaedic surgeons may consider CPN exploration at the time of ligament reconstruction, there is no standardised approach to the management of this complex and debilitating complication.This review focusses on published evidence of the outcomes of common peroneal nerve (CPN) injuries associated with knee dislocation, and proposes an algorithm for the management.

We report a case of traumatic anterior dislocation of the left knee in association with disruption of the soft tissues including knee ligaments, popliteal artery and common peroneal nerve, resulting in lower limb acute ischemia. All components of this complex trauma were recognised and treated promptly with rehabilitation commencing early. The present case is important in two aspects: firstly it reports a very rare occurrence of simultaneous anterior dislocation of the knee associated with vascular insult and common peroneal nerve injury, that was rarely reported in the current literature; secondly it highlights that with timely intervention and a team approach excellent results could be achieved...
