The aim of the study was to investigate the effects of wearing various levels of compression following repeated and exhausting sprint exercise on variables related to recovery. Twelve well-trained handball players performed three sessions of repeated and exhausting sprint exercise (30 × 30m). Directly after each session the participants wore tights extending from below the hip to the foot with either 0, 10, or 25 mm Hg of compression onto the thigh and calf muscles. 48 h after the training session all participants performed 5 × 30m sprints and counter movement jumps...

A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1-C5 spinal cord (SC) lesion. Immediately thereafter (<1 h), MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3--C4 was evidenced...

Vertebrobasilar insufficiency (VBI) provoked by physiological head rotation is known as rotational vertebral artery syndrome (RVAS) or Bow Hunter syndrome. RVAS most often occurs at C1-2 level with head rotation and presents with symptoms of VBI. Several previously published studies have reported RVAS at subaxial sites (V2 segment), however, tumor-induced RVAS has never been reported. The authors report the first case of RVAS at V2 segment due to compression from a spinal tumor. A 71-year-old man presented with symptoms of dizziness provoked by head rotation or neck extension...

PURPOSE: Our objective of this study was to evaluate if cervical compressive myelopathy (CCM) patients with preoperative abnormal magnetic resonance imaging (MRI) might easily lead to intraoperative neuromonitoring (IONM) loss. METHOD: A consecutive series of 152 CCM patients who underwent cervical cord decompression were enrolled in this study between December 2013 and February 2017. All patients with abnormal MRI signal intensity were divided into 2 groups (group 1: T2-WIs hyperintensity; group 2: both T2-WIs hyperintensity and T1-WIs hypointensity)...

PURPOSE OF REVIEW: Neuroophthalmologists and neurosurgeons are often asked by their patients what their visual prognosis will be after decompression of an optic chiasm lesion. Previous methods have been studied but have not provided consistent guidance. However, a recent algorithm which allows for retinal ganglion cell analysis from optical coherence tomography (OCT) may be more helpful. RECENT FINDINGS: Recent studies have shown that ganglion cell layer complex (GCC) measurements from OCT strongly correlate with the visual field loss associated with compressive optic neuropathies...

Injuries of the carpometacarpal joints of the long fingers are infrequent and go often unnoticed if a thorough clinical exploration and complete radiological assessment is not carried out. The overall frequency of carpometacarpal joints injuries is of 1-2% among trauma of the wrist and the carpus. These are normally secondary to high energy trauma (such as a car or a motorbike accidents). Among these kinds of injuries, the volar dislocation of the metacarpals is much less frequent than the dorsal dislocation, being even rarer the cases in which the three middle metacarpals are involved...

Most students of articular mechanics consider impact loads to be compressive forces that are borne by an intraosseous, trabecular scaffold. The possible role of marrow fat, which comprises about 75% of the structure, is generally ignored, and the potential contribution of type 1 collagen, the prototypic tensile protein, is not considered. Here, I question the evidence underlying these omissions and reject the conclusion of exclusive trabecular compression. Instead, I suggest that impact loading pressurizes the fat in subchondral compartments, and those pressures stretch the elastic trabecular walls, which are thereby subjected to tensile loading...

Bighorn sheep (Ovis canadensis) rams hurl themselves at each other at speeds of ∼9 m/s (20 mph) to fight for dominance and mating rights. This necessitates impact resistance and energy absorption mechanisms, which stem from material-structure components in horns. In this study, the material hierarchical structure as well as correlations between the structure and mechanical properties are investigated. The major microstructural elements of horns are found as tubules and cell lamellae, which are oriented with (∼30⁰) angle with respect to each other...

The high dimensionality and noisy spectra of Mass Spectrometry (MS) data are two of the main challenges to achieving high accuracy recognition. The objective of this work is to produce an accurate prediction of class content by employing compressive sensing (CS). Not only can CS significantly reduce MS data dimensionality, but it will also allow for full reconstruction of original data. We are proposing a weighted mixing of L1- and L2-norms via a regularization term as a classifier within compressive sensing framework...

The posterior interosseous nerve (PIN) is susceptible to a number of traumatic and atraumatic pathologies. In this article, we aim to review our current understanding of the etiology, pathology, diagnosis, treatment options, and published outcomes of atraumatic PIN palsy. In general, the etiology of atraumatic PIN palsy can be divided into mechanical, which is caused by an extrinsic compressive force on the nerve, and nonmechanical, which is caused by an intrinsic inflammatory reaction within the nerve. As per this discussion, there are 3 causes for atraumatic PIN palsy...

Compression of duodenum by Superior Mesenteric Artery (SMA) causing proximal intestinal obstruction is an uncommon condition. Treatment of this condition involves conservative management initially followed by surgical management in those patients who have persistent symptoms. This case series evaluates surgical management and outcome of six patients after one year, who presented with SMA syndrome and describes a brief review of literature. Three patients underwent open duodenojejunostomy and the rest three underwent laparoscopic duodenojejunostomy...

A 38-year-old woman had a 3-week gradual onset of right-sided weakness in the upper and lower extremities. MRI showed a large left petro-clival meningioma encasing the basilar and left superior cerebellar artery and compressing the brainstem. A posterior transpetrosal approach, with a left temporal and retrosigmoid craniotomy and mastoidectomy, was performed. The tumor was removed in a gross-total resection with questionable remnants adherent to the brainstem. Intraoperative partial iatrogenic injury to the left oculomotor nerve was repaired with fibrin glue...

Tenderness is an important parameter for evaluating textural properties of beef. Viscoelasticity is a comprehensive property of viscosity and elasticity. Detection of beef tenderness based on beef viscoelasticity could avoid sample destruction inherent to the traditional evaluation method. This study has built a novel detection system using an air flow supply and laser displacement sensor to evaluate beef viscoelasticity, collecting measurements of beef sample deformation from the air flow, and of the subsequent recovery occurring during a 12-second time period...

In multi-echo imaging, multiple T1/T2 weighted images of the same cross section is acquired. Acquiring multiple scans is time consuming. In order to accelerate, compressed sensing based techniques have been proposed. In recent times, it has been observed in several areas of traditional compressed sensing, that instead of using fixed basis (wavelet, DCT etc.), considerably better results can be achieved by learning the basis adaptively from the data. Motivated by these studies, we propose to employ such adaptive learning techniques to improve reconstruction of multi-echo scans...

BACKGROUND: Recurrent laryngeal nerve (RLN) injury during surgery may reveal differences in electromyographic (EMG) changes after sustained compression or traction. METHODS: In 20 pigs with the NIM-FLEX EMG-endotracheal tube, EMG was recorded at baseline, during sustained RLN compression, or traction until 70% amplitude decrease and during 30 minutes of recovery. RESULTS: Seventy percent amplitude decrease from baseline was reached after 110 ± 98 seconds (compression group) and 2034 ± 2108 seconds (traction group)...

BACKGROUND: Emergent decompression, either by closed reduction or surgical decompression, of the acutely compressed cervical spinal cord is recognized as important in minimizing the neurological outcomes of these injuries. The aim of this study is to optimize New Zealand's capability to perform closed reductions. METHODS: Regional hospitals throughout New Zealand were surveyed on their capability to reduce acute cervical spine dislocations using traction. A systematic literature review was performed to investigate aspects of patient selection, reduction technique and the outcomes achieved with closed reduction of such injuries...

Intracerebral haemorrhage (ICH) is the most devastating and disabling type of stroke. Uncontrolled hypertension (HTN) is the most common cause of spontaneous ICH. Recent advances in neuroimaging, organised stroke care, dedicated Neuro-ICUs, medical and surgical management have improved the management of ICH. Early airway protection, control of malignant HTN, urgent reversal of coagulopathy and surgical intervention may increase the chance of survival for patients with severe ICH. Intensive lowering of systolic blood pressure to <140 mm Hg is proven safe by two recent randomised trials...

External neurolysis of the nerve at fibro-osseous tunnels has been proprosed to treat or prevent signs, symptoms, and complications in the lower extremity of diabetes patients with sensorimotor polyneuropathy. Nerve decompression is justified in the presence of symptomatic compressed nerves in the several fibro-osseous tunnels of the extremities, which are known to be frequent in diabetes. Quite a body of literature has accumulated reporting results after such nerve decompression in the leg, describing pain relief and sensibility improvement, as well as balance recovery, diabetic foot ulcer prevention, curtailed ulcer recurrence risk, and amputation avoidance...
