Filter by:PEG is a fusogen, a type of chemical that aids in mediating cell fusion. PEG helps nerve cells recover neuronal continuity by removing plasmalemmal-bound water which opens the axonal ends on both sides of the injury. Opening axonal ends permits the nerve ends to reconnect and begin regeneration. PEG has been tested on animal models extensively and in earthworm models has been shown to induce fusion rates in 80-100% of neuronal cells. In crushed or severed mammalian sciatic nerves PEG has enhanced neuronal continuity to baseline functioning levels. Human applications for PEG have been tested by Bamba and colleagues in a case series with encouraging results. No studies, to our knowledge, have prospectively examined the use of PEG in peripheral nerve injuries. We propose a placebo controlled, double-blinded randomized controlled trial to test the hypothesis that local PEG administration can enhance sensory nerve regeneration following digital nerve transection compared to surgery alone.
Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.
The purpose of this study is to evaluate the role of 4-aminopyridine (4-AP) on the course of recovery after peripheral nerve traction and/or crush injury. The investigational treatment will be used to test the hypothesis that 4-aminopyridine speeds the often slow and unpredictable recovery after peripheral nerve traction and/or crush injuries.
The object of this study is to investigate the damage to the retinal nerve fiber layer (RNFL) and ganglion cell complex layer (GCL+) in diabetic patients without retinal microangioma as detected by fundus fluorescein angiography (FFA) and to determine the kind of nerve damage more likely to indicate early injury.
There is only one study in the literature about the quantitative effect of M. deltoideus on the movement of the shoulder. Here, the author described a 35-80% loss of abduction power after selective blockade of the N. axillaris. Gerber, on the other hand, found a loss of abduction force of 73-86% after blockade of the suprascapular nerve. These results are partly contradictory, which is why the investigators think that further investigation is needed. For many questions in the field of shoulder orthopedics, this knowledge would provide an important additional basis for therapeutical decision-making. For example, in the treatment of rotator cuff ruptures but also in the implantation of both inverse and anatomical shoulder prostheses. Also, statements about different outcome prognoses could be made more precisely. Therefore, the investigators would like to perform muscle strength measurements of the deltoid muscle on 12 healthy volunteers on the dominant arm. Abduction, flexion, external rotation and internal rotation Mm. Infraspinatus, Supraspinatus and Subscapularis are tested respectively. The investigators plan to carry out the measurements three times before and after an-anaesthesiological nerve block of the axillary nerve thus inactivating the deltoid muscle (performed exclusively by an anesthesiologist specialized in regional anesthesia). The success of the nerve block is confirmed by needle electromyographies (EMG) by a neurologist specialized in electrophysiology. Using EMG neurogenic pathologies within the tested muscles are also ruled out. In order to exclude relevant rotator cuff pathologies the investigators will perform shoulder radiography in three planes and sonography of the rotator cuff before conducting the experiment described above.
Traditionally, coronary angiograms are performed through the radial artery which is accessed above the palm of the 'right' hand. In recent years, some cardiologists are performing this procedure from the back of the wrist in as the radial artery courses through the anatomical snuffbox (distal radial access). The aim of this study is to determine the prevalence of hand dysfunction following coronary angiography via the distal radial artery.
A retrospective study is conducted with 59 patients who has a combination of soft tissue and digital nerve defects following trauma treated using the Littler flap or bipedicle nerve flap.Patients are divided into two groups. The group reconstructed with the Litter flap includes 26 patients and the group reconstructed with the bipedicle nerve flap includes 33 patients.Discriminatory sensation, pain and cold intolerance of the reconstructed finger, and patient satisfaction were evaluated.
To evaluate the role of 4-aminopyridine (4-AP) on the course of recovery after peripheral nerve traction and/or crush injury. This study aims to test the hypothesis that 4-aminopyridine speeds the often slow and unpredictable recovery after peripheral nerve traction and/or crush injuries.
Up to 5% of total shoulder arthroplasty patients experience transient or permanent nerve injury during surgery. In this study, we will monitor the nerve transmission of the patients' arm to detect whether the nerve is functioning normally. This techniques is called somatosensory evoked potential (SSEP) monitoring. In this study, we will assess whether SSEP monitoring could detect nerve abnormalities, alerts the surgical team enabling optimize their surgical intervention and prevent surgical related nerve injury.
Patients often report anxiety and pain related to electromyography (EMG) and nerve conduction studies (NCS) which are tests used to look for diseases of the nerves and muscles. Unfortunately, for those with very high levels of test related stress, the experience may be very frightening and may impede completion of the study and negatively impact on making a timely and accurate diagnosis. Several studies have shown that music can improve anxiety and pain levels in various situations and procedures. Our study will allow participants to play music of their choice during EMG and NCS in order to determine if the pain and anxiety that they experience is reduced.
