BACKGROUND: Chronic itch is a highly debilitating symptom that underlies many medical disorders with no universally effective treatments. Although unique neuronal signaling cascades in the sensory ganglia and spinal cord have been shown to critically promote the pathogenesis of chronic itch, the role of skin-associated cells remains poorly understood. OBJECTIVE: We sought to examine the cutaneous mechanisms underlying transient receptor potential vanilloid 4 (TRPV4)-mediated allergic and nonallergic chronic itch...

OBJECTIVE: Difficulties often encountered during intubation in extremely low birth-weight (ELBW) neonates requiring resuscitation at birth because of the smaller airway and the pressure from the limited number of attempts before hemodynamic instability occurs. CASE REPORT: We evaluated two pregnant women at 26 weeks of gestation with premature rupture of membranes and evidence of chorioamnionitis and applied the concept of ex utero intrapartum treatment, which involved delaying cord clamping (DCC) after establishing a secured airway with adequate ventilation during cesarean delivery...

Traumatic spinal cord injuries (SCIs) affect millions of people worldwide; the majority of whom are in the chronic phase of their injury. Unfortunately, most current treatments target the acute/subacute injury phase as the microenvironment of chronically injured cord consists of a well-established glial scar with inhibitory chondroitin sulfate proteoglycans (CSPGs) which acts as a potent barrier to regeneration. It has been shown that CSPGs can be degraded in vivo by intrathecal Chondroitinase ABC (ChABC) to produce a more permissive environment for regeneration by endogenous cells or transplanted neural stem cells (NSCs) in the subacute phase of injury...

Observational studies have demonstrated that placental cord drainage can shorten the length of the third stage of labour and reduce blood loss during vaginal deliveries. The aim of our work was to evaluate the existing evidence for the effectiveness of placental cord drainage in the third stage of labour. PubMed, Embase, the Cochrane Library, Web of Science, Google Scholar and 50 journals were searched up to the 4th of June, 2017. Randomized controlled trials comparing placental cord drainage with no cord drainage in the third stage of labour during vaginal delivery were included...

BACKGROUND: Spinal cord ischemia is a serious injury that threatens human health and life. Furthermore, it was widely accepted that miR-136 was mediated in the spinal injury, while whether it regulated neurocytes apoptosis in I/R-induced spinal cord injury remains unclear. METHODS: Spinal cord ischemia injury (SCII) rats were induced by clamping the nontraumatic vascular clip on the abdominal aorta. Real-time PCR was conducted to determine the mRNA expression, and western blot was carried out to measure protein expression...

Paediatric and adult resuscitation is often performed with family present. Current guidelines recommend deferred umbilical cord clamping as part of immediate neonatal care, requiring neonatal assessment next to the mother. This paper describes strategies for providing care beside the mother using both standard resuscitation equipment and a trolley designed for this purpose.

BACKGROUND: To evaluate changes in neonatal resuscitation and postnatal care following Helping Babies Breathe (HBB) training at a community hospital in rural Honduras. We hypothesized that HBB training would improve resuscitation and essential newborn care interventions. METHODS: Direct observation and video recording of delivery room care spanned before and after an initial HBB workshop held in August 2013. Rates of essential newborn care interventions were compared in resuscitations performed by individuals who had and had not received HBB training, and run charts recording performance of newborn care practices over time were developed...

Dislocation is the most common, and severe, spinal cord injury (SCI) mechanism in humans, yet there are few preclinical models. While dislocation in the rat model has been shown to produce unique outcomes, like other closed column models it exhibits higher outcome variability. Refinement of the dislocation model will enhance the testing of neuroprotective strategies, further biomechanical understanding, and guide therapeutic decisions. The overall objective of this study is to improve biomechanical repeatability of a dislocation SCI model in the rat, through the following specific aims: (i) design new injury clamps that pivot and self-align to the vertebrae; (ii) measure intervertebral kinematics during injury using the existing and redesigned clamps; and (iii) compare relative motion at the vertebrae-clamp interface to determine which clamps provide the most rigid connection...

New Australian and New Zealand Neonatal Resuscitation guidelines reflect recent advances in neonatal resuscitation science, as critically appraised by the International Liaison Committee on Resuscitation. Substantial changes since the 2010 guidelines include: (i) updates to the Newborn Resuscitation Flowchart to include a greater emphasis on maintaining normal body temperature, and to emphasise the importance of beginning assisted ventilation by 1 min in infants who have absent or ineffective spontaneous breathing; (ii) updates to the physiology of the normal perinatal transition that resuscitation is trying to restore; (iii) recommendations for more frequent reinforcement of training, and for structured feedback for resuscitation training instructors; (iv) new guidance in relation to the timing of cord clamping for preterm newborn infants; (v) recommendation to monitor body temperature on admission to newborn units as a resuscitation quality indicator; (vi) suggestion to consider electrocardiographic (ECG) monitoring (as an adjunct to oximetry) to obtain more rapid and accurate estimation of heart rate during resuscitation; (vii) removal of previous suggestions to intubate meconium-exposed, non-vigorous term infants to suction the trachea; and (viii) suggestion to establish vascular access to enable administration of intravenous adrenaline (epinephrine) as soon as chest compressions are deemed to be needed...

Sinomenium acutum has been used in traditional medicine to treat a painful disease such as rheumatic arthritis and neuralgia. Sinomenine, which is a main bioactive ingredient in Sinomenium acutum, has been reported to have an analgesic effect in diverse pain animal models. However little is known about the detailed mechanisms underlying peripheral analgesic effect of sinomenine. In the present study, we aimed to elucidate its cellular mechanism by using formalin-induced acute inflammatory pain model in mice...

Injury of the aortic isthmus is the second most frequent cause of death in cases of blunt traumatic injury. Conventional open repair is related to significant morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) has increasing role in traumatic isthmic rupture, as it avoids the thoracotomy-related morbidity, aortic cross clamping, and cardiopulmonary bypass. Additionally to the technical difficulties of open repair, multi-trauma patients may not tolerate the manipulations necessary to undergo open surgery, due to concomitant injuries...

BACKGROUND: We evaluated the incidence, clinical effect, and recovery rate of vocal cord dysfunction (VCD) and swallowing dysfunction in neonates undergoing aortic arch repair. METHODS: We retrospectively evaluated 101 neonates who underwent aortic arch reconstruction from 2008 to 2015. Direct flexible laryngoscopy was performed in 89 patients before initiation of postoperative oral feeding after Norwood (n = 63) and non-Norwood (n = 26) arch reconstruction. We defined VCD as immobility of vocal cords or their lack of coaptation and poor mobility...

We examined bladder and urethral sphincter activity in mice with or without spinal cord injury (SCI) after C-fiber afferent desensitization induced by capsaicin pretreatment and changes in electrophysiological properties of mouse bladder afferent neurons 4 weeks after SCI. Female C57BL/6N mice were divided into 4 groups; (1) spinal intact (SI)-control, (2) SI-capsaicin pretreatment (Cap), (3) SCI-control and (4) SCI-Cap groups. Continuous cystometry and external urethral sphincter (EUS)-electromyogram (EMG) were conducted under an awake condition...

A Lapillonne, O Becquet
Because of the postnatal redistribution of the iron store, the term infant born after an uneventful pregnancy virtually needs no iron during its first 6 months of life. On the other hand, several factors, such as duration of gestation, gender, mother's iron status, alteration of the iron placental transfer, significantly influence the iron store at birth. Because of their reduced body store at birth and their higher demand during catch-up growth, low birth weight infants should receive an iron supplement, which should be started earlier and given at a higher dose in the more premature infants...

BACKGROUND AND PURPOSE: The mechanism of the anti-migraine action of extracts of butterbur [Petasites hybridus (L.) Gaertn.] is unknown. Here, we investigated the ability of isopetasin, a major constituent of these extracts, to specifically target TRPA1 channel and to affect functional responses relevant to migraine. EXPERIMENTAL APPROACH: Single-cell calcium imaging and patch-clamp recordings in human and rodent TRPA1-expressing cells, neurogenic motor responses in rodent isolated urinary bladder, release of CGRP from mouse spinal cord in vitro and facial rubbing in mice and meningeal blood flow in rats were examined...

BACKGROUND: In a previous study we compared rocuronium and suxamethonium for rapid-sequence induction of general anaesthesia for caesarean section and found no difference in maternal outcome. There was however, a significant difference in Apgar scores. As this was a secondary outcome, we extended the study to explore this finding on a larger sample. METHODS: We included 488 parturients of whom 240 were women from the original study. Women were randomly assigned to receive either rocuronium 1mg/kg (ROC n=245) or suxamethonium 1mg/kg (SUX n=243) after propofol 2mg/kg...
