BACKGROUND: The invasive nature of the current methods for monitoring of intracranial pressure (ICP) has prevented their use in many clinical situations. Several attempts have been made to develop methods to monitor ICP non-invasively. The aim of this study is to assess the relationship between ultrasound-based non-invasive ICP (nICP) and invasive ICP measurement in neurocritical care patients. METHODS AND FINDINGS: This was a prospective, single-cohort observational study of patients admitted to a tertiary neurocritical care unit...

Determining the etiology of ulnar-sided wrist pain is often challenging. The condition may be acute or chronic, and differential diagnoses include injuries to the ulnar carpal bones, ligament tears, tendinitis, vascular conditions, osteoarthritis and systemic arthritis, and ulnar nerve compression. An anatomically based, methodical physical examination coupled with provocative maneuvers, including piano key, ulnar impaction, shuck, foveal stress, and extensor carpi ulnaris synergy tests, further defines the differential diagnosis...

BACKGROUND: Patients with facial fracture or head and neck surgery sometimes suffer from infraorbital nerve injury. This injury results in severe hemilateral numbness in the midfacial area. The infraorbital nerve ends with two major branches; the infra nasal branch (INB) and superior labial branch (SLB). In this study, we assessed the feasibility of cross-nerve transfer of the INB and SLB based on a cadaver study. METHODS: The INB/SLB from a total 20 sides of 10 cadavers (2 men and 8 women; average age, 79...

Vilmos Bíró
For a long time in the clinical practice the autologous nerve transplants are used in reconstruction of the segmental defects of injured hand nerves. The published outcomes, especially in case of the motor and mixed (sensory and motor) nerves, however, were not satisfactory. Hence, it remained a problem and in the focus of research. The author aimed to study this topic and drawing conclusions in his literary review publication. According to the recent results, the replacement of the autologous nerve transplants with other materials (e...

Pain associated to mechanical and chemical irritation of the eye surface is mediated by trigeminal ganglia mechano- and polymodal nociceptor neurons while cold thermoreceptors detect wetness and reflexly maintain basal tear production and blinking rate. These neurons project into two regions of the trigeminal brain stem nuclear complex: ViVc, activated by changes in the moisture of the ocular surface and VcC1, mediating sensory-discriminative aspects of ocular pain and reflex blinking. ViVc ocular neurons project to brain regions that control lacrimation and spontaneous blinking and to the sensory thalamus...

A 20-year-old college trumpet player presented with a 3-month history of upper lip numbness and worsening playing ability after a marching band performance. Examination demonstrated anesthesia of the upper lip following the borders of the trumpet mouthpiece. While playing, the patient had poor range and an airy tone quality. A prescription of complete embouchure rest for 6 weeks and a tailored return to play regimen resulted in resolution of upper lip numbness and improved trumpet playing. Neuropathy of the lip in a brass player is uncommon but highlights the uniqueness of injuries that may be sustained by performing artists...

Ischemia-reperfusion (IR) in the rat femoral artery has been proposed as an experimental model of vasculitic peripheral neuropathy (VPN) which presents neuropathic pain and peripheral nerve injury patterns observed clinically. This study investigates the involvement of the proinflammatory signaling pathway underlying the peripheral mechanisms of VPN. Male Sprague-Dawley rats were allocated to receive either a sham operation or IR. IR was induced by occluding the right femoral artery for 4hours followed by reperfusion periods from 0 to 72hours...

The rostral anterior cingulate cortex (rACC) is a key structure in mediating the negative affective component of chronic pain. Brain-derived neurotrophic factor (BDNF) is known to play a critical role in activity-dependent synaptic plasticity, learning and memory. It has been shown that BDNF signalling in the rACC might be involved in spontaneous pain-related aversion, but its underlying mechanism is still largely unknown. To address this question, we measured the mRNA and protein levels of BDNF in the rACC after nerve injury and found that BDNF expression was markedly higher in nerve-injured rats than in controls...

Transplantation of a biosynthetic nerve conduit carrying neuro-protective cytokines is promising for treating peripheral nerve injury. Here we developed a novel strategy for repairing sciatic nerve injury by EPO-loaded Chitosan nerve conduit (EPO/Chi) and sandwiched-in transplantation of mesenchymal stem cells (MSCs). Then, the beneficial effect of EPO/Chi + MSCs on nerve regeneration was also further investigated by in vitro cellular experiments. In vivo experiment showed that combination of EPO-loaded Chitosan nerve conduit with MSCs could significantly accelerate nerve healing and improve morphological repair...

BACKGROUND: Gestational diabetes is a risk factor for perinatal complications; include shoulder dystocia, birth injuries such as bone fractures and nerve palsies. It is associated with later development of type 2 diabetes, the risk of macrosomia and other long-term health effects of infants born to diabetic mothers. The study assesses placental peptides and maternal factors as potential predictors of gestational diabetes among pregnant women. MATERIAL AND METHODS: A total of 200 pregnant women were recruited for the study, 150 pregnant women without pre gestational diabetes including 50 women with low risk factors of diabetes as controls and 50 other pregnant women with pregestational diabetes as control...
