To study the prion-like behavior of misfolded alpha-synuclein, mouse models are needed that allow fast and simple transmission of alpha-synuclein prionoids, which cause neuropathology within the central nervous system (CNS). Here we describe that intraglossal or intraperitoneal injection of alpha-synuclein fibrils into bigenic Tg(M83(+/-):Gfap-luc(+/-)) mice, which overexpress human alpha-synuclein with the A53T mutation from the prion protein promoter and firefly luciferase from the promoter for glial fibrillary acidic protein (Gfap), is sufficient to induce neuropathologic disease...

Unilateral high cervical spinal hemisection (i.e., C2Hx) interrupts the respiratory bulbospinal pathway and results in paralysis of the hemidiaphragm. The ipsilateral diaphragmatic activity can partially recover over weeks to months; however, its contribution to the tidal volume generation is less than 20 %. Accordingly, we hypothesized that the contralateral diaphragm exert a compensatory function to maintain the essential ventilation following cervical spinal cord hemisection. The cardiorespiratory pattern and bilateral diaphragm electromyogram (EMG) were measured in urethane-anesthetized and spontaneously breathing adult rats at 1 day, 2 or 8 weeks post-C2Hx or C2 laminectomy...

The 2'5'-oligoadenylate synthetase (OAS) is an interferon (IFN)-induced protein that plays an important role in the antiviral action of IFN, with OAS3 being one of the four OAS classes (OAS1, OAS2, OAS3, OASL). The effect of OAS on several infectious viral diseases has been reported; however, a study of the effect of OAS3 on enterovirus 71 (EV71) is lacking. The purpose of this study was to evaluate the association of the OAS3 rs1859330 G/A genetic polymorphism with susceptibility and severity of EV71 infection...

The 2014 enterovirus D68 (EV-D68) outbreak in the United States raised concerns about the introduction of the virus in the Caribbean region. The objective of this study was to provide rapid evidence of the introduction of EV-D68 strains in the Caribbean region during the 2014 outbreak in the United States, using a relatively simple phylogenetic approach. From October 2014 to May 2015, four EV-D68 cases from two countries (Bermuda and Dominica) were detected at the regional referral laboratory at the Caribbean Public Health Agency (Port of Spain, Trinidad and Tobago) based on molecular testing of respiratory specimens...

Pulmonary artery sling (PAS) is a rare congenital condition in which the left pulmonary artery (LPA) arises from the right pulmonary artery, and then passes between the trachea and the esophagus to reach the left lung, thereby forming a sling around the airway. It is often associated with intrinsic tracheal stenosis due to complete cartilaginous rings. Therapeutic management nowadays consists of one-stage reimplantation of the LPA and tracheoplasty with cardiopulmonary bypass support. Here, we present a 7-week-old boy with PAS and long-segment tracheal stenosis (LSTS) who underwent surgical intervention consisting of reimplantation of the LPA and slide tracheoplasty...

Laryngotracheal surgery has an inherent risk of injury to the recurrent laryngeal nerves (RLN). These complications go from minor dysphonia to even bilateral vocal cord paralysis. The intraoperative neuromonitoring of the RLN was developed in the field of thyroid surgery, in order to preserve nerve and vocal cord function. However, tracheal surgery requires in-field intubation of the distal trachea, which limits the use of nerve monitoring using conventional endotracheal tube with surface electrodes. Given these challenges, we present an alternative method for nerve monitoring during laryngotracheal surgery through the insertion of electrodes within the endolaryngeal musculature by bilateral puncture...

Recent successes in malaria control have been largely attributable to the deployment of insecticide-based vector control tools such as bed nets and indoor residual spraying. Pyrethroid-treated bed nets are acutely neurotoxic to mosquitoes, inducing symptoms such as loss of coordination, paralysis, and violent spasms. One result of pyrethroid exposure often seen in laboratory tests is mosquito leg loss, a condition that has thus far been assumed to equate to mortality, as females are not expected to blood feed...

Esophagectomy for esophageal cancer is invasive thoracic surgery with a high incidence rate of postoperative complications and prolongation of hospitalization, even if the standardized clinical pathway improves the outcome (mortality and morbidity). Postoperative recurrent nerve paralysis (RNP) is related to respiratory complications concomitant with prolonged hospitalization. However, it has not been elucidated which factors affect the incidence and recovery of RNP. To detect the predictive factor for postoperative RNP, we focused on preoperative serum albumin...

Severe neuropathy is a known adverse effect of vincristine in patients with Charcot-Marie-Tooth disease (CMT). We present the case of a 16-year-old girl with anaplastic medulloblastoma treated with gross total resection and high-dose craniospinal radiation with adjuvant vincristine chemotherapy who developed acute-onset severe quadriplegia and vocal cord paralysis. Vincristine and radiation therapy were discontinued. Although her neuropathy slowly improved over several weeks, she developed metastatic extraneural medulloblastoma and died 5 months after diagnosis...

Guillain-Barré syndrome is a rare condition in pregnancy which is characterised by symmetrical progressive ascending polyneuropathy. A case of a 16-year-old nulliparous woman who presented with rapidly progressive limb paralysis following an upper respiratory tract infection a week prior to presentation is discussed. She was intubated as she had developed respiratory failure and managed in the intensive care unit by a multidisciplinary team. Plasma exchange and intravenous immunoglobulin were not readily available so she was managed conservatively...

OBJECTIVE: Unilateral vocal cord paralysis (UVCP) not only induces severe dysphonia, but aspiration as well. Although laryngeal framework surgery is usually performed to treat this condition, the procedure is not tolerated by some patients. In the previous study, basic fibroblast growth factor (bFGF) injections for vocal cord scarring and sulcus have been reported to provide favorable outcomes while being minimally invasive. In this study, the authors retrospectively investigated phonological outcomes after bFGF injection in patients with UVCP...
