    This study aimed to determine the value of laryngeal electromyography in the prognosis of vocal fold paralysis. This is a retrospective descriptive study. This study included 80 patients diagnosed with unilateral or bilateral vocal fold paralysis on flexible laryngoscopy between 2002 and 2014 in a tertiary medical center. Laryngeal electromyography using a standardized protocol was performed; the outcome measures were classified and analyzed into two groups according to the degree of injury. Group 1 included patients with mild to moderate injury, and group 2 included patients with severe to complete injury. Prognosis was correlated with vocal fold motion recovery status with a minimum of 6 months of follow-up since the symptoms onset using positive and negative predictive values. Sixty patients showed acute or chronic recurrent laryngeal neuropathy in laryngeal electromyography. Twelve of 41 patients included in group 1 recovered motion, and 30 of 35 patients included in group 2 did not recover, resulting in 88.2% of positive predictive value and 35.7% of negative predictive value. Our data confirm that laryngeal electromyography is a useful clinical tool in predicting poor recovery in patients with vocal fold paralysis. It allows identification of candidates for early intervention. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

  2. Ulnar nerve paralysis after forearm bone fracture

    Full Text Available ABSTRACT Paralysis or nerve injury associated with fractures of forearm bones fracture is rare and is more common in exposed fractures with large soft-tissue injuries. Ulnar nerve paralysis is a rare condition associated with closed fractures of the forearm. In most cases, the cause of paralysis is nerve contusion, which evolves with neuropraxia. However, nerve lacerations and entrapment at the fracture site always need to be borne in mind. This becomes more important when neuropraxia appears or worsens after reduction of a closed fracture of the forearm has been completed. The importance of diagnosing this injury and differentiating its features lies in the fact that, depending on the type of lesion, different types of management will be chosen.

    To estimate the prevalence and causes of functional paralysis in the United States. We used the 2013 US Paralysis Prevalence & Health Disparities Survey to estimate the prevalence of paralysis, its causes, associated sociodemographic characteristics, and health effects among this population. Nearly 5.4 million persons live with paralysis. Most persons with paralysis were younger than 65 years (72.1%), female (51.7%), White (71.4%), high school graduates (64.8%), married or living with a partner (47.4%), and unable to work (41.8%). Stroke is the leading cause of paralysis, affecting 33.7% of the population with paralysis, followed by spinal cord injury (27.3%), multiple sclerosis (18.6%), and cerebral palsy (8.3%). According to the functional definition, persons living with paralysis represent a large segment of the US population, and two thirds of them are between ages 18 and 64 years. Targeted health promotion that uses inclusion strategies to account for functional limitations related to paralysis can be undertaken in partnership with state and local health departments.

    @@ Abducent paralysis is a kind of the pathological change of the cranial nerve, manifested mainly by the clinical symptoms of inward strabismus, limited abduction of the eyeball and double vision. It is believed in modern medicine that this disease can be caused by pathological change of the pons, basicranial metastatic carcinoma, elevated intracranial pressure, and also by inflammation in the head and face, rupture of local small blood vessels or traumatic injury. Now, Prof. WU Lian-zhong's experience in the treatment of abducent paralysis is reported in the following.

    Retrospective case-control study. The purpose of this study was to examine the factors of postoperative paralysis in patients who have undergone thoracic ossification of posterior longitudinal ligament (OPLL) surgery. A higher percentage of thoracic OPLL patients experience postoperative aggravation of paralysis than cervical OPLL patients, including patients that presented great difficulties in treatment. However, there were a few reports to prevent paralysis thoracic OPLL. The 156 patients who had received thoracic OPLL surgery were selected as the subjects of this study. The items for review were the duration of disease; the preoperative muscle strength (Muscle Manual Testing); OPLL levels (T1/2-4/5: high, T5/6-8/9: middle, and T9/10-11/12: low); the spinal canal occupancy ratio; the ratio of yellow ligament ossification as a complication; the ratio of transcranial-motor evoked potential (Tc-MEP) derivation; the preoperative/postoperative kyphotic angles in the thoracic vertebrae; the correction angle of kyphosis; the duration of surgery; and the amount of bleeding. The subjects were divided into two groups based on the absence or presence of postoperative paralysis to determine the factors of postoperative paralysis. Twenty-three patients (14.7%) exhibited postoperative paralysis. Multivariate analysis identified factors associated with postoperative paralysis: the duration of disease (odds ratio, OR = 3.3); the correction angle of kyphosis (OR = 2.4); and the ratio of Tc-MEP derivation (OR = 2.2). The risk factors of postoperative paralysis are a short duration of disease and a small correction angle of kyphosis. In addition, ratios of Tc-MEP derivation below 50% may anticipate paralysis. 4.

    The present authors report a case of unilateral traumatic oculomotor nerve paralysis which shows interesting CT findings which suggest its mechanism. A 60-year-old woman was admitted to our hospital with a cerebral concussion soon after a traffic accident. A CT scan was performed soon after admission. A high-density spot was noted at the medial aspect of the left cerebral peduncle, where the oculomotor nerve emerged from the midbrain, and an irregular, slender, high-density area was delineated in the right dorsolateral surface of the midbrain. Although the right hemiparesis had already improved by the next morning, the function of the left oculomotor nerve has been completely disturbed for the three months since the injury. In our case, it is speculated that an avulsion of the left oculomotor nerve rootlet occurred at the time of impact as the mechanism of the oculomotor nerve paralysis. A CT taken soon after the head injury showed a high-density spot; this was considered to be a hemorrhage occurring because of the avulsion of the nerve rootlet at the medial surface of the cerebral peduncle.

    1981-01-01

    As part of an investigation on late non-neoplastic injury induced by negative pi-mesons (pions), a series of studies have been performed using pion beams for the induction of spinal cord paralysis in the Fisher 344 rat. Groups of rats were exposed to 1, 5 or 15 daily doses of peak pions or X rays. Paralysis appeared earlier after treatment with pions than after X-rays even in a comparison of groups with similar final incidences. A single dose RBE for spinal cord paralysis of 1.3 was found. The RBE rises to a value of 3.2 if the total dose is given as a series of 15 daily exposures. These RBEs are far larger than those observed using other late injury end-points, such as tubular degeneration in the kidney or fibrosis and sclerosis in the support structures of the colon for which the single dose RBE is less than 1.2. The biological and/or physical basis for the high sensitivity of the spinal cord to peak pions has not yet been resolved, but these data have suggested caution in exposing the spinal cord to peak pions in clinical trials.

    1986-01-01

    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself

    Full Text Available This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly.

    Full Text Available Background: Sleep paralysis is one of the many conditions of which visual hallucinations can be a part but has received relatively little attention. It can be associated with other dramatic symptoms of a psychotic nature likely to cause diagnostic uncertainty. Methods and results: These points are illustrated by the case of a young man with a severe bipolar affective disorder who independently developed terrifying visual, auditory and somatic hallucinatory episodes at sleep onset, associated with a sense of evil influence and presence. The episodes were not obviously related to his psychiatric disorder. Past diagnoses included nightmares and night terrors. Review provided no convincing evidence of various other sleep disorders nor physical conditions in which hallucinatory experiences can occur. A diagnosis of predormital isolated sleep paralysis was made and appropriate treatment recommended. Conclusions: Sleep paralysis, common in the general population, can be associated with dramatic auxiliary symptoms suggestive of a psychotic state. Less common forms are either part of the narcolepsy syndrome or (rarely they are familial in type. Interestingly, sleep paralysis (especially breathing difficulty features prominently in the folklore of various countries.

  15. Bilateral Facial Paralysis Caused by Bilateral Temporal Bone Fracture: A Case Report and a Literature Review

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

    Objective: To describe the CT appearance of recurrent laryngeal nerve paralysis, discuss the anatomic and pathologic basis of this paralysis, and evaluate CT diagnosis. Methods: 32 cases of recurrent laryngeal nerve paralysis clinical confirmed were analyzed retrospectively. All of these patients had the CT scans from the level of hyoid bone to the upper thorax, the slice and interval are 5 mm. Results: CT findings of recurrent laryngeal nerve paralysis included: oblique of aryepiglottic fold, dislocation of arytenoid cartilage and cricoarytenoid joint, dilation and relaxation of piriform sinus for 27 cases (84.4%); wide and asymmetrical ventricle of larynx for 16 cases (50.0%); asymmetrical and fix of vocal fold for 11 cases (34.4%) et al. Conclusion: The recurrent laryngeal nerve innervate all the intrinsic muscles of the larynx except cricothyroid muscle, paralysis of the nerve leads to atrophy of related muscles. CT scan demonstrate the larynx morphologic changes of recurrent nerve paralysis and is helpful to identify the etiology. (authors)

    2015-08-01

    Complete flaccid facial paralysis, as well as the synkinetic and hyperkinetic sequelae of partial recovery, has significant impact on quality of life. Patients suffer from functional deficiencies, cosmetic deformity, discomfort and social consequences leading to emotional distress. Despite an extensive and sophisticated array of available interventions for facial reanimation, most patients have persistent issues that require consistent follow-up. In long-term management, botulinum toxin (BT) injection remains a critical tool in the treatment of the facial paralysis patient, particularly in the case of synkinesis, hyperkinesis and imbalance. We review the recent scientific literature and highlight key principles and developments in the use of BT in the management of facial paralysis, including less common applications for acute facial paralysis, hyperlacrimation and pseudoptosis. We reviewed the literature for the latest advances in the use of BT in facial paralysis, including applications and technique, as well as measurement tools and adjunct exercises. We also share our experience in treating our own patient population. BT continues to be a well tolerated and effective tool in the long-term management of facial paralysis, specifically in treating synkinesis, imbalance and hyperkinesis, as well as hyperlacrimation and pseudoptosis. Consistent measurement tools and adjunct neuromuscular retraining are crucial in the successful deployment of BT. Controversy exists as to whether BT should be used to manage facial paralysis during the acute phase, and whether BT application to the nonparalyzed face can improve long-term recovery in the paralyzed side.

    Full Text Available Background: Acute hypokalemic paralysis, characterized by acute flaccid paralysis is primarily a calcium channelopathy, but secondary causes like renal tubular acidosis (RTA, thyrotoxic periodic paralysis (TPP, primary hyperaldosteronism, Gitelman′s syndrome are also frequent. Objective: To study the etiology, varied presentations, and outcome after therapy of patients with hypokalemic paralysis. Materials And Methods: All patients who presented with acute flaccid paralysis with hypokalemia from October 2009 to September 2011 were included in the study. A detailed physical examination and laboratory tests including serum electrolytes, serum creatine phosphokinase (CPK, urine analysis, arterial blood gas analysis, thyroid hormones estimation, and electrocardiogram were carried out. Patients were further investigated for any secondary causes and treated with potassium supplementation. Result: The study included 56 patients aged 15-92 years (mean 36.76 ± 13.72, including 15 female patients. Twenty-four patients had hypokalemic paralysis due to secondary cause, which included 4 with distal RTA, 4 with Gitelman syndrome, 3 with TPP, 2 each with hypothyroidism, gastroenteritis, and Liddle′s syndrome, 1 primary hyperaldosteronism, 3 with alcoholism, and 1 with dengue fever. Two female patients were antinuclear antibody-positive. Eleven patient had atypical presentation (neck muscle weakness in 4, bladder involvement in 3, 1 each with finger drop and foot drop, tetany in 1, and calf hypertrophy in 1, and 2 patient had respiratory paralysis. Five patients had positive family history of similar illness. All patients improved dramatically with potassium supplementation. Conclusion: A high percentage (42.9% of secondary cause for hypokalemic paralysis warrants that the underlying cause must be adequately addressed to prevent the persistence or recurrence of paralysis.

    Full Text Available Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability. In this study we investigate whether electroacupuncture (EA at Zusanli (ST36 could prevent severe scalds-induced gut ischemia, paralysis, and barrier dysfunction and whether the protective role of EA at ST36 is related to the vagus nerve. 35% burn area rats were divided into six groups: (a EAN: EA nonchannel acupoints followed by scald injury; (b EA: EA at ST36 after scald injury; (c VGX/EA: vagotomy (VGX before EA at ST36 and scald injury; (d VGX/EAN: VGX before EAN and scald injury; (e atropine/EA: applying atropine before scald injury and then EA at ST36; (f atropine/EAN: applying atropine before scald injury and then EA at nonchannel acupoints. EA at the Zusanli point significantly promoted the intestinal impelling ratio and increased the amount of mucosal blood flow after scald injury. The plasma diamine oxidase (DAO and intestinal permeability decreased significantly after scald injury in the EA group compared with others. However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

    Full Text Available Background: Acquired paralysis of the diaphragm is a condition caused by trauma, surgical injuries, (lung cancer surgery, esophageal surgery, cardiac surgery, thoracic surgery, and is sometimes of an unknown etiology. It can lead to dyspnea and can affect ventilatory function and patients activity. Diaphragmatic plication is a treatment method which decreases inconsistent function of diaphragm. The aim of this study is to evaluate the outcome of diaphragmatic plication in patients with acquired unilateral non-malignant diaphragmatic paralysis. Methods: From 1991 to 2011, 20 patients with acquired unilateral diaphragmatic paralysis who underwent surgery enrolled in our study in Ghaem Hospital Mashhad University of Medical Science. Patients were evaluated in terms of age, sex, BMI, clinical symptoms, dyspnea score (DS, etiology of paralysis, diagnostic methods, respiratory function tests and complication of surgery. Some tests including dyspnea score were carried out again six months after surgery. We evaluated patients with SPSS version 11.5 and Paired t-test or nonparametric equivalent. Results: Twenty patients enrolled in our study. 14 were male and 6 were female. The mean age was 58 years and the average time interval between diagnosis to surgical treatment was 38.3 months. Acquired diaphragmatic paralysis was mostly caused by trauma (in 11 patients and almost occurred on the left side (in 15 patients. Diagnostic methods included chest x-ray, CT scan, ultrasonography and sniff. Test prior to surgery the average FVC was 41.4±7 percent and the average FEV1 was 52.4±6 percent and after surgery they were 80.1±8.6 percent and 74.4±1 percent respectively. The average increase in FEV1 and FVC 63.4±4, 61.1±7.8. Performing surgery also leads to a noticeable improvement in dyspnea score in our study. Conclusion: In patients with acquired unilateral non-malignant diaphragm paralysis diaphragmatic plication is highly recommended due to the

  3. Treatment of rat spinal cord injury with the neurotrophic factor albumin-oleic acid: translational application for paralysis, spasticity and pain.

    Directory of Open Access Journals (Sweden)

    Gerardo Avila-Martin

    Full Text Available Sensorimotor dysfunction following incomplete spinal cord injury (iSCI is often characterized by the debilitating symptoms of paralysis, spasticity and pain, which require treatment with novel pleiotropic pharmacological agents. Previous in vitro studies suggest that Albumin (Alb and Oleic Acid (OA may play a role together as an endogenous neurotrophic factor. Although Alb can promote basic recovery of motor function after iSCI, the therapeutic effect of OA or Alb-OA on a known translational measure of SCI associated with symptoms of spasticity and change in nociception has not been studied. Following T9 spinal contusion injury in Wistar rats, intrathecal treatment with: i Saline, ii Alb (0.4 nanomoles, iii OA (80 nanomoles, iv Alb-Elaidic acid (0.4/80 nanomoles, or v Alb-OA (0.4/80 nanomoles were evaluated on basic motor function, temporal summation of noxious reflex activity, and with a new test of descending modulation of spinal activity below the SCI up to one month after injury. Albumin, OA and Alb-OA treatment inhibited nociceptive Tibialis Anterior (TA reflex activity. Moreover Alb-OA synergistically promoted early recovery of locomotor activity to 50 ± 10% of control and promoted de novo phasic descending inhibition of TA noxious reflex activity to 47 ± 5% following non-invasive electrical conditioning stimulation applied above the iSCI. Spinal L4-L5 immunohistochemistry demonstrated a unique increase in serotonin fibre innervation up to 4.2 ± 1.1 and 2.3 ± 0.3 fold within the dorsal and ventral horn respectively with Alb-OA treatment when compared to uninjured tissue, in addition to a reduction in NR1 NMDA receptor phosphorylation and microglia reactivity. Early recovery of voluntary motor function accompanied with tonic and de novo phasic descending inhibition of nociceptive TA flexor reflex activity following Alb-OA treatment, mediated via known endogenous spinal mechanisms of action, suggests a clinical application of this novel

    2014-02-01

    Hemi-diaphragmatic paralysis is the most common complication associated with cryoballoon ablation for atrial fibrillation, yet the histopathology of phrenic nerve injury has not been well described. A preclinical randomized study was conducted to characterize the histopathology of phrenic nerve injury induced by cryoballoon ablation and assess the potential for electromyographic (EMG) monitoring to limit phrenic nerve damage. Thirty-two dogs underwent cryoballoon ablation of the right superior pulmonary vein with the objective of inducing phrenic nerve injury. Animals were randomized 1:1 to standard monitoring (i.e., interruption of ablation upon reduction in diaphragmatic motion) versus EMG guidance (i.e., cessation of ablation upon a 30% reduction in the diaphragmatic compound motor action potential [CMAP] amplitude). The acute procedural endpoint was achieved in all dogs. Phrenic nerve injury was characterized by Wallerian degeneration, with subperineural injury to large myelinated axons and evidence of axonal regeneration. The degree of phrenic nerve injury paralleled the reduction in CMAP amplitude (P = 0.007). Animals randomized to EMG guidance had a lower incidence of acute hemi-diaphragmatic paralysis (50% vs 100%; P = 0.001), persistent paralysis at 30 days (21% vs 75%; multivariate odds ratio 0.12, 95% confidence interval [0.02, 0.69], P = 0.017), and a lesser severity of histologic injury (P = 0.001). Mature pulmonary vein ablation lesion characteristics, including circumferentiality and transmurality, were similar in both groups. Phrenic nerve injury induced by cryoballoon ablation is axonal in nature and characterized by Wallerian degeneration, with potential for recovery. An EMG-guided approach is superior to standard monitoring in limiting phrenic nerve damage. © 2013 Wiley Periodicals, Inc.

    Vocal fold paresis and paralysis are common conditions. Treatment options include augmentation laryngoplasty and voice therapy. The optimal management for this condition is unclear. The objective of this study was to assess possible neuromuscular compensation mechanisms that could potentially be used in the treatment of vocal fold paresis and paralysis. In vivo canine model. In an in vivo canine model, we examined three conditions: 1) unilateral right recurrent laryngeal nerve (RLN) paresis and paralysis, 2) unilateral superior laryngeal nerve (SLN) paralysis, and 3) unilateral vagal nerve paresis and paralysis. Phonatory acoustics and aerodynamics were measured in each of these conditions. Effective compensation was defined as improved acoustic and aerodynamic profile. The most effective compensation for all conditions was increasing RLN activation and decreasing glottal gap. Increasing RLN activation increased the percentage of possible phonatory conditions that achieved phonation onset. SLN activation generally led to decreased number of total phonation onset conditions within each category. Differential effects of SLN (cricothyroid [CT] muscle) activation were seen. Ipsilateral SLN activation could compensate for RLN paralysis; normal CT compensated well in unilateral SLN paralysis; and in vagal paresis/paralysis, contralateral SLN and RLN displayed antagonistic relationships. Methods to improve glottal closure should be the primary treatment for large glottal gaps. Neuromuscular compensation is possible for paresis.

    Closed temporal bone fractures due to cranial trauma often result in facial nerve injury, frequently inducing incomplete facial paralysis. Conventional hypoglossal-facial nerve end-to-end neurorrhaphy may not be suitable for these injuries because sacrifice of the lesioned facial nerve for neurorrhaphy destroys the remnant axons and/or potential spontaneous innervation. we modified the classical method by hypoglossal-facial nerve "side"-to-side neurorrhaphy using an interpositional predegenerated nerve graft to treat these injuries. Five patients who experienced facial paralysis resulting from closed temporal bone fractures due to cranial trauma were treated with the "side"-to-side neurorrhaphy. An additional 4 patients did not receive the neurorrhaphy and served as controls. Before treatment, all patients had suffered House-Brackmann (H-B) grade V or VI facial paralysis for a mean of 5 months. During the 12-30 months of follow-up period, no further detectable deficits were observed, but an improvement in facial nerve function was evidenced over time in the 5 neurorrhaphy-treated patients. At the end of follow-up, the improved facial function reached H-B grade II in 3, grade III in 1 and grade IV in 1 of the 5 patients, consistent with the electrophysiological examinations. In the control group, two patients showed slightly spontaneous innervation with facial function improved from H-B grade VI to V, and the other patients remained unchanged at H-B grade V or VI. We concluded that the hypoglossal-facial nerve "side"-to-side neurorrhaphy can preserve the injured facial nerve and is suitable for treating significant incomplete facial paralysis resulting from closed temporal bone fractures, providing an evident beneficial effect. Moreover, this treatment may be performed earlier after the onset of facial paralysis in order to reduce the unfavorable changes to the injured facial nerve and atrophy of its target muscles due to long-term denervation and allow axonal

    Profound hypokalemic conditions resulting from cisplatin therapy have been known to produce hypokalemic paralysis in rare cases. We describe such a case of cisplatin-induced hypokalemic paralysis. A 15-year-old Persian girl with ovarian dysgerminoma presented with severe generalized weakness and paraplegia 1 week after the fourth course of cisplatin-based chemotherapy. On physical examination, there was symmetric flaccid paralysis and areflexia in all of the extremities and particularly in the lower limbs. Her serum potassium concentration was 1.7 mmol/L. Metastatic disease was excluded by a comprehensive systemic evaluation. Complete clinical and paraclinical recovery was achieved after short-term administration of potassium supplement. Adverse drug reactions are common with cisplatin, but the drug is only rarely associated with hypokalemic paralysis. Based on the Naranjo causality algorithm, an objective assessment revealed cisplatin to be a probable cause of hypokalemic paralysis in this case. This adverse drug event--whether isolated or secondary to hypomagnesemia--may be deceptive, leading to a fatal mistake in the oncology setting, and should therefore be precisely differentiated from cancer-related complications. This case suggests that cisplatin should be added to the list of agents causing hypokalemic paralysis. Regular serum electrolyte measurement, the early detection of cation deficiency, and appropriate replacement of cations are all recommended.

    The objective of this study was to evaluate the effectiveness of methylprednisolone (MP) in models of facial nerve paralysis obtained by nerve section, compression, or inoculation with herpes simplex virus (HSV). Experimental controlled animal study. Tertiary referral center. A total of 30 female New Zealand rabbits weighing 1200-3000 g were used for the study. They were randomly assigned to one of 6 groups of 5 animals each. A nerve section injury was realized in Groups 1a (section and MP) and 1b (section, control) rabbits. A compression-type injury was inflicted to rabbits in Groups 2a (compression and MP) and 2b (compression, control). As for animals in Groups 3a (Type 1 HSV and MP) and 3b (Type 1 HSV, controls), facial nerve paralysis resulting from viral infection was obtained. Animals in the 3 treatment groups, designated with the letter "a", were administered MP, 1 mg/kg/d, whereas those in control groups "b" received 1 mL normal saline, both during 3 weeks. All subjects were followed up for 2 months. At the end of this period, all animals had the buccal branch of the facial nerve excised on the operated side. Semi-thin sections of these specimens were evaluated under light microscopy for the following: perineural fibrosis, increase in collagen fibers, myelin degeneration, axonal degeneration, Schwann cell proliferation, and edema. No significant difference was observed (P > 0.05) between the MP treatment group and the control group with regard to perineural fibrosis, increase in collagen fibers, myelin degeneration, axonal degeneration, edema, or Schwann cell proliferation. In the group with a compressive lesion (Group 2), controls were no different from MP-treated animals as to perineural fibrosis, increase in collagen fibers, or Schwann cell proliferation, whereas axonal degeneration, myelin degeneration, and edema were significantly higher (P facial nerve palsy, we may say that this drug was without effect on nerve healing in paralysis due to nerve

    Magnetic resonance (MR) images of a total of 195 patients with cervical (125) or thoracic (70) spinal cord injury were reviewed. The imaging studies of the spinal cord lesions were correlated with clinical manifestations. Sequential MR imaging revealed hypointensity on T1-weighted images (T1WI) and hyperintensity on T2-weighted images (T2WI) in all patients, except for five patients showing no signal changes and two showing isointensity, suggesting gliosis, myelomalacia, and syringomyelia. Spinal cord lesions were classified into four types: small lesions, large lesions, complete transverse, and longitudinal rupture. These lesions were well correlated with the severity of injury and paralysis. Complete paralysis was frequently associated with enlarged, complete transverse for cervical spinal cord injury, and longitudinal ruptured or thinned complete transverse for thoracic spinal cord injury. The height of paralysis was well in agreement with that of lesions. For incomplete paralysis, localized lesions were seen within the spinal cord, coinciding with the paralysis or severity. Traumatic syringomyelia was seen in 17 patients (8.7%)-- for the cervical site (10 patients, 8%) and the thoracic site (7 patients, 10%). When homogeneous and marginally clear hypointensity is shown on T1-weighted images and vacuolated hyperintensity is shown on T2-weighted images, in addition to lesions spreading two or more cords or 1.5 or more cords above the nervous root level of paralysis, traumatic syringomyelia is strongly suspected, requiring the follow up observation.

    Unilateral diaphragmatic paralysis causes respiratory deficits and can occur after iatrogenic or traumatic phrenic nerve injury in the neck or chest. Patients are evaluated using spirometry and imaging studies; however, phrenic nerve conduction studies and electromyography are not widely available or considered; thus, the degree of dysfunction is often unknown. Treatment has been limited to diaphragmatic plication. Phrenic nerve operations to restore diaphragmatic function may broaden therapeutic options. An interventional study of 92 patients with symptomatic diaphragmatic paralysis assigned 68 (based on their clinical condition) to phrenic nerve surgical intervention (PS), 24 to nonsurgical (NS) care, and evaluated a third group of 68 patients (derived from literature review) treated with diaphragmatic plication (DP). Variables for assessment included spirometry, the Short-Form 36-Item survey, electrodiagnostics, and complications. In the PS group, there was an average 13% improvement in forced expiratory volume in 1 second (p Phrenic nerve operations for functional restoration of the paralyzed diaphragm should be part of the standard treatment algorithm in the management of symptomatic patients with this condition. Assessment of neuromuscular dysfunction can aid in determining the most effective therapy. Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    An in vivo study of skeletal muscle paralysis induced by intravenous barium chloride has been made in curarized and non-curarized rats. The influence of potassium and calcium chlorides, propranolol, ouabain, and prior adrenalectomy on the paralysis has also been studied. Paralysis is found to be due to a direct effect on skeletal muscle, and to correlate well with the development of hypokalaemia. Possible mechanisms of action of barium are discussed, and attention is drawn to the similarity between barium poisoning and hypokalaemic familial periodic paralysis. PMID:4813426

    To examine the causes of sport-related spinal cord injuries that developed into paraplegia or tetraplegia, and to compare data from different sports with previous studies in the same geographical region. A retrospective epidemiological study and comparison with previous studies. The Orthopedic Department, specializing in the treatment and rehabilitation of paralyzed patients, at the University of Heidelberg, Germany. Between 1985 and 1997, 1,016 cases of traumatic spinal cord injury presented at the Orthopedic Department at the University of Heidelberg: 6.8% were caused by sport and 7.7% by diving accidents. Sport-related spinal cord injuries with paralysis. A total of 1.016 cases of traumatic spinal cord injury were reviewed. Of these, 14.5% were caused by sport accidents (n = 69) or diving accidents (n = 78). Age of patients ranged from 9 to 52 years. 83% were male. 77% of the patients developed tetraplegia, and 23%, paraplegia. 16 of the sport accidents resulted from downhill skiing, 9 resulted from horseback riding, 7 from modern air sports, 6 from gymnastics, 5 from trampolining, and 26 from other sports. Previous analyses had revealed that paraplegia had mainly occurred from gymnastics, trampolining, or high diving accidents. More recently, however, the number of serious spinal injuries caused by risk-filled sports such as hang gliding and paragliding has significantly increased (p = 0.095), as it has for horseback riding and skiing. Examinations have shown that all patients who were involved in diving accidents developed tetraplegia. An analysis of injury from specific sports is still under way. Analysis of accidents resulting in damage to the spinal cord in respect to different sports shows that sports that have become popular during the last 10 years show an increasing risk of injury. Modern air sports hold the most injuries. Injury-preventing strategies also are presented.

    Injury to the recurrent laryngeal nerve (RLN) is a dreaded complication of endocrine surgery. Intraoperative neural monitoring (IONM) has been increasingly utilized to assess the functional status of the RLN. Although the posterior cricoarytenoid muscle (PCA) is innervated by the RLN as the abductor of the larynx, PCA electromyography (EMG) is infrequently recorded during IONM and PCA activity after RLN compressive injury remains poorly characterized. Single-subject prospective animal study. We employed a canine model to identify postcricoid EMG correlates of postoperative vocal cord paralysis (VCP). Postcricoid electrode recordings were obtained before and after compressive RLN injury associated with VCP. Normative postcricoid recordings revealed mean amplitude of 1288 microvolt (μV) and latency of 8.2 millisecond (ms) with maximum (1 milliamp [mA]) vagal stimulation, and mean amplitude of 1807 μV and latency of 3.5 ms with maximum (1 mA) RLN stimulation. Following injury that was associated with VCP, there was 62.1% decrement in postcricoid EMG amplitude with maximum vagal stimulation and 80% decrement with maximum RLN stimulation. Threshold stimulation of the vagus increased by 23%, and there was a corresponding 42% decrease in amplitude. For RLN stimulation, latency increased by 17.3% following injury, whereas threshold stimulation increased by 61% with 35.5% decrement in EMG amplitude. Thus, if RLN amplitude decreases by ≥ 80%, with absolute amplitude of ≤ 300 μV or less and latency increase of ≥ 10%, RLN injury is likely associated with VCP. Our results predict postoperative VCP based on postcricoid electromyographic IONM and may guide surgical decision making.

    Aim: To compile imaging findings in patients with vocal fold paralysis. Materials and methods: A retrospective analysis of the medical charts of 100 consecutive patients, admitted to our department with vocal fold paralysis was undertaken. After laryngoscopy, patients were referred for radiological work-up depending on their clinical history and clinical findings. Ultrasound of the neck and/or contrast-enhanced spiral computed tomography (CT) of the neck and mediastinum was performed, extending to include the whole chest if necessary. In one patient, CT of the brain and in two patients, magnetic resonance angiography was undertaken. Analysis of the clinical and radiological data was performed to assess the most frequent causes for vocal fold paralysis. Results: In 66% of patients, the paralysis was related to previous surgery. Thirty-four percent of cases were labelled idiopathic after clinical examination. After imaging and follow-up, only 8% remained unexplained. Nine patients suffered from neoplasms, four from vascular disease, and 12 from infections. One patient developed encephalomyelitis disseminata on follow-up. Conclusion: Thorough radiological work-up helps to reduce the amount of idiopathic cases of vocal fold paralysis and guides appropriate therapy.

    Diaphragmatic paralysis is a rare cause of respiratory distress in the newborn. In this paper, a patient with unilateral phrenic nerve injury after traumatic delivery is presented. The child inadequately responded to standard respiratory supportive measures. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA®), providing an optimally synchronized respiratory support proportional to the effort of the patient, resulted in prompt clinical and biological improvement of the patient's respiratory condition. NAVA is a relatively new mode of ventilation in neonatal care. In this case of unilateral diaphragmatic paralysis, it provided an alternative strategy of non-invasive respiratory support avoiding prolonged mechanical ventilation.

    Vocal fold paralysis is usually recognized in laryngological examination, and detailed vocal fold function may be established based on laryngovideostroboscopy. Additional imaging should exclude any morphological causes of the paresis, which should be treated pharmacologically or surgically. The aim of this paper was to analyze the computed tomography (CT) images of the larynx in patients with unilateral vocal fold paralysis. CT examinations of the larynx were performed in 10 patients with clinically defined unilateral vocal fold paralysis. The examinations consisted of unenhanced acquisition and enhanced 3-phased acquisition: during free breathing, Valsalva maneuver, and phonation. The analysis included the following morphologic features of the paresis.the deepened epiglottic vallecula, the deepened piriform recess, the thickened and medially positioned aryepiglottic fold, the widened laryngeal pouch, the anteriorly positioned arytenoid cartilage, the thickened vocal fold, and the filled infraglottic space in frontal CT reconstruction. CT images were compared to laryngovideostroboscopy. The most common symptoms of vocal cord paralysis in CT were the deepened epiglottic vallecula and piriform recess, the widened laryngeal pouch with the filled infraglottic space, and the thickened aryepiglottic fold. Regarding the efficiency of the paralysis determination, the three functional techniques of CT larynx imaging used did not differ significantly, and laryngovideostroboscopy demonstrated its advantage over CT. CT of the larynx is a supplementary examination in the diagnosis of vocal fold paralysis, which may enable topographic analysis of the fold dysfunction. The knowledge of morphological CT features of the paralysis may help to prevent false-positive diagnosis of laryngeal cancer. (author)

  1. Right hypoglossal nerve paralysis after tracheal intubation for aesthetic breast surgery

    Full Text Available Aesthetic and functional complications caused by general anesthesia have been rarely described after aesthetic surgery. We report a case of unilateral right hypoglossal nerve paralysis following the use of a cuffed endotracheal airway in a 24-year-old woman undergoing aesthetic breast surgery. Neurological examination and magnetic resonance imaging of the head failed to provide additional insights into the cause of the nerve injury. Postoperatively, the patient was carefully monitored and made a full recovery within 2 weeks without any pharmacological treatment. The transient hypoglossal nerve paralysis seemed to be due to neuropraxia. In this patient, we postulate that the right hypoglossal nerve was compressed between the endotracheal tube cuff and the hyoid bone, which was inflated with 30 cm H 2 O. Patients undergoing aesthetic surgery must be appropriately and adequately informed that postoperative aesthetic and functional deficits can occur due to anesthesia as well as the surgery.

    Acute exposure of ectotherms to critically high temperatures causes injury and death, and this mortality has been associated with a number of physiological perturbations including impaired oxygen transport, loss of ion and water homeostasis, and neuronal failure. It is difficult to discern which of these factors, if any, is the proximate cause of heat injury because, for example, loss of ion homeostasis can impair neuromuscular function (including cardiac function), and conversely impaired oxygen transport reduces ATP supply and can thus reduce ion transport capacity. In this study we investigated if heat stress causes a loss of ion homeostasis in marine crabs and examined if such loss is related to heart failure. We held crabs (Carcinus maenas) at temperatures just below their critical thermal maximum and measured extracellular (hemolymph) and intracellular (muscle) ion concentrations over time. Analysis of Arrhenius plots for heart rates during heating ramps revealed a breakpoint temperature below which heart rate increased with temperature, and above which heart rate declined until complete cardiac failure. As hypothesised, heat stress reduced the Nernst equilibrium potentials of both K + and Na + , likely causing a depolarization of the membrane potential. To examine whether this loss of ion balance was likely to cause disruption of neuromuscular function, we exposed crabs to the same temperatures, but this time measured ion concentrations at the individual-specific times of complete paralysis (from which the crabs never recovered), and at the time of cardiac failure. Loss of ion balance was observed only after both paralysis and complete heart failure had occurred; indicating that the loss of neuromuscular function is not caused by a loss of ion homeostasis. Instead we suggest that the observed loss of ion balance may be linked to tissue damage related to heat death. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Unilateral vocal fold paralysis with no preceding causes is diagnosed as idiopathic unilateral vocal fold paralysis. However, comprehensive guidelines for evaluating the defining characteristics of idiopathic unilateral vocal fold paralysis are still lacking. In the present study, we hypothesized that idiopathic unilateral vocal fold paralysis may have different clinical and neurologic characteristics from unilateral vocal fold paralysis caused by surgical trauma. Retrospective, case series study. Patients with unilateral vocal fold paralysis were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form-36 Health Survey quality-of-life questionnaire. Patients with idiopathic and iatrogenic vocal fold paralysis were compared. A total of 124 patients were recruited. Of those, 17 with no definite identified causes after evaluation and follow-up were assigned to the idiopathic group. The remaining 107 patients with surgery-induced vocal fold paralysis were assigned to the iatrogenic group. Patients in the idiopathic group had higher recruitment of the thyroarytenoid-lateral cricoarytenoid muscle complex and better quality of life compared with the iatrogenic group. Idiopathic unilateral vocal fold paralysis has a distinct clinical presentation, with relatively minor denervation changes in the involved laryngeal muscles, and less impact on quality of life compared with iatrogenic vocal fold paralysis. 4.

    Full Text Available Periodic paralysis is a rare neuromuscular disorder, related to a defect in muscle ion channels, characterized by episodes of painless muscle weakness, which may be precipitated by heavy exercise, fasting, or high-carbohydrate meals. Hypokalemic periodic paralysis may be familial (primary or secondary. Here, we report three cases of secondary causes of hypokalemic periodic paralysis. On evaluation, case 1 had distal renal tubular acidosis (RTA due to Sjogren′s syndrome, case 2 had drug induced proximal RTA (Fanconi′s syndrome and case 3 had thyrotoxicosis. Clinician must be aware of causes of secondary PP as recognition and diagnosis can completely prevent further attacks of periodic paralysis. Each of the above case is rare, but completely treatable if diagnosed. Low dose steroids with bicarbonate replacement in case 1, stopping tenofovir in case 2 and carbimazole therapy in case 3 prevented further attacks of periodic paralysis and cardiopulmonary complications.

    We have gathered 159 cases of facial paralysis from recent records in our hospital, including paralyses of central as well as peripheral origin, and presenting as the only symptom or as one of several major symptoms of the discomfort of each patient. Sixty-four percent of them were studied by CT scan and/or MR, confirming the existence of alterations in the pathway of nerve pair VII in 50% of the patients who underwent radiological study. Idiopathic facial paralysis was the most common type (42% of the total); while tumors and post-traumatic findings were the most constant radiological findings. From the analysis of the data, the importance of the clinical criteria for selection of the patients in the study and the protocol for radiological diagnosis employed can be deduced. (author)

    In Australia, tick paralysis in dogs (caused by a toxin in the saliva of Ixodes species during feeding) is a serious, distressing condition, and untreated it is often fatal. The aim of this study was to quantify the association between parkland (recreational or natural) in an urban area and the occurrence of canine tick paralysis. Brisbane, as a large urban centre located within the zone of paralysis tick habitat along the east coast of Australia, was selected as the study area. Postcodes selected for inclusion were those defined as being of an urban character (Australian Bureau of Statistics). The number of natural and recreational parkland polygons and total land area per postcode were derived. Tick paralysis case data for the selected postcodes were extracted from a national companion animal disease surveillance database. Between October 2010 and January 2017, 1650 cases of tick paralysis in dogs were reported and included in this study. Significant correlations were found between the number of reported cases per postcode and parklands: natural counts, 0.584 (P edges of the study area - either coastal or on the urban fringe; no clusters were identified within the core urban zone of the study area. Of the disease cases included in this study, strong seasonality was evidence: 68% of all cases were identified in spring. Within urban environments, areas of natural vegetation in particular appear to pose a risk for tick paralysis in dogs. This evidence can be used by veterinarians and dog owners to reduce the impact of tick paralysis by raising awareness of risk areas so as to enhance prevention via chemoprophylaxis and targeted searches of pet dogs for attached ticks.

    To describe a series of cases of vocal fold paralysis years after radiation therapy, including presentation, clinical course, and treatment. Case series with chart review. Tertiary care center. A review of 8 years of patient records yielded 10 patients (8 male and 2 female; average age 57 years [range, 29-76 years]) with vocal fold paralysis and a history of radiation therapy to the head, neck, or mediastinum. These patients did not have other possible etiologies of vocal fold paralysis. Demographic, diagnostic, clinical course, and treatment data were collected. On average, 21 years (range, 1-27 years) elapsed between completion of radiation and presentation with vocal fold paralysis. Original pathologies included Hodgkin lymphoma (5), squamous cell carcinoma of the head and neck (4), and peripheral T-cell lymphoma (1). Eight patients had unilateral left vocal fold paralysis, and 2 had bilateral neuropathy; none recovered spontaneously. All patients had dysphonia, and nearly all patients also complained of dysphagia. Six elected not to be treated. Four underwent injection augmentation with resolution of voice complaints. Radiation therapy has the potential to cause laryngeal neuropathy years to decades after treatment. The potential for recovery is low, but injection augmentation can relieve symptoms. Development of contralateral neuropathy and altered tissue response are considerations in treatment. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Profound hypokalemia with paralysis usually poses a diagnostic and therapeutic challenge. We report on a 28-y-old obese Chinese female presenting with sudden onset of flaccid quadriparesis upon awaking in the morning. There is no family history of hyperthyroidism. She experienced body weight loss of 7 kg in 2 months. The most conspicuous blood biochemistry is marked hypokalemia (1.8 mmol/l) and hypophosphatemia (0.5 mmol/l) associated with low urine K(+) and phosphate excretion. Surreptitious laxatives and/or diuretics abuse-related hypokalemic paralysis were tentatively made. However, her relatively normal blood acid-base status and the absence of low urine Na(+) and/or Cl(-) excretion made these diagnoses unlikely. Furthermore, she developed rebound hyperkalemia (5.7 mmol/l) after only 80 mmol K(+) supplementation. Thyroid function test confirmed hyperthyroidism due to Graves' disease. Control of the hyperthyroidism completely abolished her periodic paralysis. Thyrotoxic periodic paralysis (TPP) should be kept in mind as a cause of paralysis in female, even with obesity, despite its predominance in adult males. Copyright © 2012 Elsevier B.V.

    MR studies were performed in three patients with paralysis in the lower extremities. Poliomyelitis-like paralysis can be caused by neurovirulent strains of nonpolioenteroviruses. Entervirus 71 (EV 71) is documented as one of the potentially neurovirulent strains and a causative agent of some epidemics (1-7). The clinical manifestations associated with the EV 71 infection include aseptic meningitis, hand-food-mouth disease (HFMD), acute respiratory illness and gastrointestinal disease(6). Although rarely fatal, flaccidparalysis can be followed by EV 71 induced aseptic meningitis. Anterior horn cell necrosis was suggested on MR in two patients with residual paralysis (7). MR features, however, have not yet been described in detail. In this report we present three cases of patients with clinical evidence of EV 71 induced aseptic meningitis whose MR studies showed residual changes in spinal cord.

    Hypokalemic periodic paralysis (HPP) is a rare disorder characterised by acute, potentially fatal atacks of muscle weakness or paralysis. Massive shift of potassium into cells is caused by elevated levels of insulin and catecholamines in the blood. Hypophosphatemia and hypomagnesemia may be also present. Acidobasic status usually is not impaired. HPP occurs as familiar (caused by ion channels inherited defects) or acquired (in patients with hyperthyroidism). On the basis of two clinical cases we present a review of hypokalemic periodic paralysis in hyperthyroid patients. We discuss patogenesis, clinical and laboratory findings as well as the principles of prevention and treatment of this rare disorder.

    Electrical stimulation of the phrenic nerve to pace the diaphragm in patients with chronic ventilatory insufficiency has been an established therapeutic modality since William W.L. Glenn first described using radiofrequency signals in 1978 to stimulate the phrenic nerves. Before this event, patients who were ventilator-dependent and thus bedridden because of respiratory paralysis associated with quadriplegia usually anticipated little chance for physical or psychosocial rehabilitation. Two cases of C1-C2 subluxtion with cord injury and chronic ventilatory insufficiency were implanted at VGH-Taipei with diaphragm pacemaker in 1988. Postoperative phrenic nerve stimulation was given according to individual training schedule. One case with total phrenic paralysis received bilateral phrenic nerve stimulation and became weaned from the ventilator 6 months later. The other case with partially active ventilatory function received unilateral phrenic nerve stimulation to compensate the ventilation. However, its final outcome still showed the necessity of a bilateral mode to achieve adequate ventilation irrespective of strenuous training for 2 years.

    The aim of this study was to describe the association between climate, weather and the occurrence of canine tick paralysis, feline tick paralysis and canine parvovirus in Australia. The Southern Oscillation Index (SOI) and monthly average rainfall (mm) data were used as indices for climate and weather, respectively. Case data were extracted from a voluntary national companion animal disease surveillance resource. Climate and weather data were obtained from the Australian Government Bureau of Meteorology. During the 4-year study period (January 2010-December 2013), a total of 4742 canine parvovirus cases and 8417 tick paralysis cases were reported. No significant (P ≥ 0.05) correlations were found between the SOI and parvovirus, canine tick paralysis or feline tick paralysis. A significant (P parvovirus occurrence and rainfall in the same month (0.28), and significant negative cross-correlations (-0.26 to -0.36) between parvovirus occurrence and rainfall 4-6 months previously. Significant (P canine tick paralysis occurrence and rainfall 1-3 months previously, and significant positive cross-correlations (0.29-0.47) between canine tick paralysis occurrence and rainfall 7-10 months previously. Significant positive cross-correlations (0.37-0.68) were found between cases of feline tick paralysis and rainfall 6-10 months previously. These findings may offer a useful tool for the management and prevention of tick paralysis and canine parvovirus, by providing an evidence base supporting the recommendations of veterinarians to clients thus reducing the impact of these diseases.

    Full Text Available Acute flaccid paralysis (AFP is a complex clinical syndrome with a broad array of potential etiologies that vary with age. We present our experience of acute onset lower motor neuron paralysis. Materials and Methods: One hundred and thirty-three consecutive adult patients presenting with weakness of duration less than four weeks over 12 months period were enrolled. Detailed history, clinical examination, and relevant investigations according to a pre-defined diagnostic algorithm were carried out. The patients were followed through their hospital stay till discharge or death. Results: The mean age was 33.27 (range 13-89 years with male preponderance (67.7%. The most common etiology was neuroparalytic snake envenomation (51.9%, followed by Guillain Barre syndrome (33.1%, constituting 85% of all patients. Hypokalemic paralysis (7.5% and acute intermittent porphyria (4.5% were the other important conditions. We did not encounter any case of acute polio mylitis in adults. In-hospital mortality due to respiratory paralysis was 9%. Conclusion: Neuroparalytic snakebite and Guillain Barre syndrome were the most common causes of acute flaccid paralysis in adults in our study.

    Full Text Available Primary periodic paralysis is a rare autosomal dominant disorder of ion-channel dysfunction, manifested by episodic flaccid paresis secondary to abnormal sarcolemma excitability. Membrane destabilization involving Na, K-ATPase has been hypothesized to be a biological etiology of the bipolar disorder (BD and the mechanisms underlying lithium therapy have been linked to it. To date, there has been only one reported case of BD comorbid with periodic paralysis. Herein, we reported another case of concurrent bipolar mania and hypokalemic periodic paralysis (HPP, one special form of periodic paralysis. Consistent with the previous case, our patient responded well to lithium treatment for both bipolar mania and HPP. This might provide some support to the hypothesis that the therapeutic effects of lithium in both BD and HPP could be due to the correction of the underlying common pathophysiology.

    A retrospective, single-institute, and radiographic study. To evaluate the relationship between the epidural spinal cord compression (ESCC) scale and the severity of metastatic spine tumor-induced paralysis. The ESCC scale is used to evaluate the grade of spinal cord compression on T2-weighted magnetic resonance imaging (MRI). However, few studies have investigated the relationship between such MRI findings and paralysis. The subjects were 467 patients with metastatic spine tumors and grade 1b or worse spinal cord compression according to the ESCC scale. Evaluations using this scale were performed by three spine surgeons, and results that were obtained by two or more surgeons were adopted. We also examined patients whose spinal cord compression deteriorated by one grade or more to American Spinal Injury Association (ASIA) grade C or worse within the first 3 weeks after MRI. The kappa coefficients for inter- and intraexaminer variability were 0.90 and 0.95, respectively. ASIA grade D or worse paralysis developed in at least 50% of the patients with ESCC grade 1b or worse spinal cord compression at the C1-T2 and at least 50% of those with ESCC grade 1c or worse spinal cord compression at the T3-L5. The frequency of ASIA grade C or worse paralysis was high among the patients with ESCC grade 2 or worse spinal cord compression at the C7-L1. Nineteen patients experienced rapid deterioration of one grade or more to ASIA grade C or worse paralysis within the first 3 weeks after MRI. Of these, paralysis occurred in at least 30% of the patients with anterolateral or circumferential cord compression combined with ESCC grade 2 or 3 compression at the C7-L1. The severity of paralysis was not correlated with the ESCC scale. Patients with anterolateral or circumferential ESCC grade 2 or 3 cord compression at the C7-L1 are at high risk of rapidly progressive paralysis. 4.

    Objective. Brain-computer interface (BCI) technology aims to provide individuals with paralysis a means to restore function. Electrocorticography (ECoG) uses disc electrodes placed on either the surface of the dura or the cortex to record field potential activity. ECoG has been proposed as a viable neural recording modality for BCI systems, potentially providing stable, long-term recordings of cortical activity with high spatial and temporal resolution. Previously we have demonstrated that a subject with spinal cord injury (SCI) could control an ECoG-based BCI system with up to three degrees of freedom (Wang et al 2013 PLoS One). Here, we expand upon these findings by including brain-control results from two additional subjects with upper-limb paralysis due to amyotrophic lateral sclerosis and brachial plexus injury, and investigate the potential of motor and somatosensory cortical areas to enable BCI control. Approach. Individuals were implanted with high-density ECoG electrode grids over sensorimotor cortical areas for less than 30 d. Subjects were trained to control a BCI by employing a somatotopic control strategy where high-gamma activity from attempted arm and hand movements drove the velocity of a cursor. Main results. Participants were capable of generating robust cortical modulation that was differentiable across attempted arm and hand movements of their paralyzed limb. Furthermore, all subjects were capable of voluntarily modulating this activity to control movement of a computer cursor with up to three degrees of freedom using the somatotopic control strategy. Additionally, for those subjects with electrode coverage of somatosensory cortex, we found that somatosensory cortex was capable of supporting ECoG-based BCI control. Significance. These results demonstrate the feasibility of ECoG-based BCI systems for individuals with paralysis as well as highlight some of the key challenges that must be overcome before such systems are translated to the clinical

    Spinal cord injury devastates the CNS, besetting patients with symptoms including but not limited to: paralysis, autonomic nervous dysfunction, pain disorders and depression. Despite the identification of several molecular and genetic factors, a reliable regenerative therapy has yet to be produced for this terminal disease. Perhaps the missing piece of this puzzle will be discovered within endogenous electrotactic cellular behaviors. Neurons and stem cells both show mediated responses (growth rate, migration, differentiation) to electromagnetic waves, including direct current electric fields. This review analyzes the pathophysiology of spinal cord injury, the rationale for regenerative cell therapy and the evidence for directing cell therapy via electromagnetic waves shown by in vitro experiments.

    Full Text Available The principal symptoms of unilateral vocal fold paralysis are hoarseness and difficulty in swallowing. Dyspnea is comparatively rare (Laccourreye et al., 2003. The extent to which unilateral vocal fold paralysis may lead to respiratory problems at all - in contrast to bilateral vocal fold paralysis- has not yet well been determined. On the one hand, inspiration is impaired with unilateral vocal fold paralysis; on the other hand, neither the position of the vocal fold paralysis nor the degree of breathiness correlates with respiratory parameters (Cantarella et al., 2003; 2005. The question of what respiratory stress a patient with a vocal fold paresis can endure has not yet been dealt with.A 43 year-old female patient was suffering from recurrent unspecific respiratory complaints for four months after physical activity. During training for a marathon, she experienced no difficulty in breathing. These unspecific respiratory complaints occurred only after athletic activity and persisted for hours. The patient observed neither an increased coughing nor a stridor. Her voice remained unaltered during the attacks, nor were there any signs of a symptomatic gastroesophageal reflux or infectious disease. A cardio-pulmonary and a radiological examination by means of an X-ray of the thorax also revealed no pathological phenomena. As antiallergic and antiobstructive therapy remained unsuccessful, a laryngological examination was performed in order to exclude a vocal cord dysfunction.Surprisingly enough, the laryngostroboscopy showed, as an initial description, a vocal fold paralysis of the left vocal fold in median position (Figure 1. The anamnestic background for the cause was unclear. The only clue was a thoracotomy on the left side due to a pleuritis in childhood. A subsequent laryngoscopic examination had never been performed. Good mucosa waves and amplitudes were shown bilateral with complete glottal closure. Neither in the acoustic analysis, nor in the

    Hypokalemic Periodic Paralysis is one form of Periodic Paralysis, a rare group of disorders that can cause of sudden onset weakness. A case of a 29 year old male is presented here. The patient presented with sudden onset paralysis of his extremities. Laboratory evaluation revealed a markedly low potassium level. The patient's paralysis resolved upon repletion of his low potassium and he was discharged with no neurologic deficits. An association with thyroid disease is well established and further workup revealed Grave's disease in this patient. Although rare, Periodic Paralysis must differentiated from other causes of weakness and paralysis so that the proper treatment can be initiated quickly. PMID:18939979

    We explore the existence and underlying neural mechanism of a new norm endorsed by both black and white Americans for managing interracial interactions: "racial paralysis', the tendency to opt out of decisions involving members of different races. We show that people are more willing to make choices--such as who is more intelligent, or who is more polite-between two white individuals (same-race decisions) than between a white and a black individual (cross-race decisions), a tendency which was evident more when judgments involved traits related to black stereotypes. We use functional magnetic resonance imaging to examine the mechanisms underlying racial paralysis, to examine the mechanisms underlying racial paralysis, revealing greater recruitment of brain regions implicated in socially appropriate behavior (ventromedial prefrontal cortex), conflict detection (anterior cingulate cortex), deliberative processing (dorsolateral prefrontal cortex), and inhibition (ventrolateral prefrontal cortex). We also discuss the impact of racial paralysis on the quality of interracial relations.

    Facial paralysis has been a recognized condition since Antiquity, and was mentionned by Hippocratus. In the 17th century, in 1687, the Dutch physician Stalpart Van der Wiel rendered a detailed observation. It was, however, Charles Bell who, in 1821, provided the description that specified the role of the facial nerve. Facial nerve surgery began at the end of the 19th century. Three different techniques were used successively: nerve anastomosis, (XI-VII Balance 1895, XII-VII, Korte 1903), myoplasties (Lexer 1908), and suspensions (Stein 1913). Bunnell successfully accomplished the first direct facial nerve repair in the temporal bone, in 1927, and in 1932 Balance and Duel experimented with nerve grafts. Thanks to progress in microsurgical techniques, the first faciofacial anastomosis was realized in 1970 (Smith, Scaramella), and an account of the first microneurovascular muscle transfer published in 1976 by Harii. Treatment of the eyelid paralysis was at the origin of numerous operations beginning in the 1960s; including palpebral spring (Morel Fatio 1962) silicone sling (Arion 1972), upperlid loading with gold plate (Illig 1968), magnets (Muhlbauer 1973) and transfacial nerve grafts (Anderl 1973). By the end of the 20th century, surgeons had at their disposal a wide range of valid techniques for facial nerve surgery, including modernized versions of older techniques.

    Full Text Available Background and objectives : Current levels of AFP care system have created the possibility to demonstrate the significant decrease in pathogenesis of poliomyelitis. To ensure the success of polio eradication, intensification of AFP care system in a way that it can confirm the lack of polio virus outbreak in areas that have no reports of confirmed cases of this disease, seemed to be essential. This research aimed to represent some features of disease symptoms and final diagnosis of the reported cases and investigate the age, gender, time and geographical zone and the incidence of acute flaccid paralysis cases in the province within 2008-2011.     Material and Methods : Data for the cases of AFP were collected from all cities in the province from 20/3/2008- 19/3/2013 and were analyzed using descriptive methods (census method. Results: Discovery and reporting 95% of acute flaccid paralysis cases up to 7 days from the occurrence of paralysis, preparing two qualitative samples from 98% acute flaccid paralysis up to 14 days from the occurrence of paralysis, tracking and evaluating 100% of acute flaccid paralysis after 60 days of disease occurrence, on-time sending/receiving 98% of the samples to national laboratory, show the capabilities of provincial care system.   Conclusion : Despite the excellent care of acute flaccid paralysis in the East Azerbaijan, it seems that the role of health care facilities and rural and urban health centers and private clinics in identification and reporting of acute flaccid paralysis is non-significant since only 5% of the cases were reported at local levels.

    2016-08-01

    Full Text Available Introduction This study on intratemporal facial paralysis is an attempt to understand the aetiology of facial nerve paralysis, effect of different management protocols and the outcome after long-term follow-up. Materials and Methods A prospective longitudinal study was conducted from September 2005 to August 2008 at the Department of Otorhinolaryngology of a medical college in Kolkata comprising 50 patients of intratemporal facial palsy. All cases were periodically followed up for at least 6 months and their prognostic outcome along with different treatment options were analyzed. Result Among different causes of facial palsy, Bell’s palsy is the commonest cause; whereas cholesteatoma and granulation were common findings in otogenic facial palsy. Traumatic facial palsies were exclusively due to longitudinal fracture of temporal bone running through geniculate ganglion. Herpes zoster oticus and neoplasia related facial palsies had significantly poorer outcome. Discussion Otogenic facial palsy showed excellent outcome after mastoid exploration and facial decompression. Transcanal decompression was performed in traumatic facial palsies showing inadequate recovery. Complete removal of cholesteatoma over dehiscent facial nerve gave better postoperative recovery. Conclusion The stapedial reflex test is the most objective and reproducible of all topodiagnostic tests. Return of the stapedial reflex within 3 weeks of injury indicates good prognosis. Bell’s palsy responded well to conservative measures. All traumatic facial palsies were due to longitudinal fracture and 2/3rd of these patients showed favourable outcome with medical therapy.

    2014-02-01

    Our aim was to describe our experience with the masseteric nerve in the reanimation of short term facial paralysis. We present our outcomes using a quantitative measurement system and discuss its advantages and disadvantages. Between 2000 and 2012, 23 patients had their facial paralysis reanimated by masseteric-facial coaptation. All patients are presented with complete unilateral paralysis. Their background, the aetiology of the paralysis, and the surgical details were recorded. A retrospective study of movement analysis was made using an automatic optical system (Facial Clima). Commissural excursion and commissural contraction velocity were also recorded. The mean age at reanimation was 43(8) years. The aetiology of the facial paralysis included acoustic neurinoma, fracture of the skull base, schwannoma of the facial nerve, resection of a cholesteatoma, and varicella zoster infection. The mean time duration of facial paralysis was 16(5) months. Follow-up was more than 2 years in all patients except 1 in whom it was 12 months. The mean duration to recovery of tone (as reported by the patient) was 67(11) days. Postoperative commissural excursion was 8(4)mm for the reanimated side and 8(3)mm for the healthy side (p=0.4). Likewise, commissural contraction velocity was 38(10)mm/s for the reanimated side and 43(12)mm/s for the healthy side (p=0.23). Mean percentage of recovery was 92(5)mm for commissural excursion and 79(15)mm/s for commissural contraction velocity. Masseteric nerve transposition is a reliable and reproducible option for the reanimation of short term facial paralysis with reduced donor site morbidity and good symmetry with the opposite healthy side.

    Full Text Available Background: Hypokalemic paralysis is characterized by episodes of acute muscle weakness associated with hypokalemia. In this study, we evaluated the possible etiological factors in patients of hypokalemic paralysis. Materials and Methods: We reviewed the records of 29 patients who were admitted with a diagnosis of hypokalemic paralysis. Modified Guillain-Barre΄ Syndrome disability scale was used to grade the disability. Results: In this study, 15 (51.7% patients had secondary causes of hypokalemic paralysis and 14 patients (42.3% had idiopathic hypokalemic paralysis. Thyrotoxicosis was present in six patients (20.6%, dengue infection in four patients (13.7%, distal renal tubular acidosis in three patients (10.3%, Gitelman syndrome in one patient (3.4%, and Conn′s syndrome in one patient (3.4%. Preceding history of fever and rapid recovery was seen in dengue infection-induced hypokalemic paralysis. Approximately 62% patients had elevated serum creatinine phosphokinase. All patients had recovered completely following potassium supplementation. Patients with secondary causes were older in age, had significantly more disability, lower serum potassium levels, and took longer time to recover. Conclusion: In conclusion, more than half of patients had secondary causes responsible for hypokalemic paralysis. Dengue virus infection was the second leading cause of hypokalemic paralysis, after thyrotoxicosis. Presence of severe disability, severe hypokalemia, and a late disease onset suggested secondary hypokalemic paralysis.

    Chronic bee paralysis virus (CBPV) causes a disease characterized by trembling, flightless, and crawling bees, while Acute bee paralysis virus (ABPV) is commonly detected in apparently healthy colonies, usually associated to Varroa destructor. Both viruses had been detected in most regions of the world, except in South America. In this work, we detected CBPV and ABPV in samples of Uruguayan honeybees by RT-PCR. The detection of both viruses in different provinces and the fact that most of the analyzed samples were infected, suggest that, they are widely spread in the region. This is the first record of the presence of CBPV and ABPV in Uruguay and South America.

  16. Surgery for traumatic facial nerve paralysis: does intraoperative monitoring have a role?

    Ashram, Yasmine A; Badr-El-Dine, Mohamed M K

    2014-09-01

    The use of intraoperative facial nerve (FN) monitoring during surgical decompression of the FN is underscored because surgery is indicated when the FN shows more than 90 % axonal degeneration. The present study proposes including intraoperative monitoring to facilitate decision taking and provide prognostication with more accuracy. This prospective study was conducted on ten patients presenting with complete FN paralysis due to temporal bone fracture. They were referred after variable time intervals for FN exploration and decompression. Intraoperative supramaximal electric stimulation (2-3 mA) of the FN was attempted in all patients both proximal and distal to the site of injury. Postoperative FN function was assessed using House-Brackmann (HB) scale. All patients had follow-up period ranging from 7 to 42 months. Three different patterns of neurophysiological responses were characterized. Responses were recorded proximal and distal to the lesion in five patients (pattern 1); only distal to the lesion in two patients (pattern 2); and neither proximal nor distal to the lesion in three patients (pattern 3). Sporadic, mechanically elicited EMG activity was recorded in eight out of ten patients. Patients with pattern 1 had favorable prognosis with postoperative function ranging between grade I and III. Pattern 3 patients showing no mechanically elicited activity had poor prognosis. Intraoperative monitoring affects decision taking during surgery for traumatic FN paralysis and provides prognostication with sufficient accuracy. The detection of mechanically elicited EMG activity is an additional sign predicting favorable outcome. However, absence of responses did not alter surgeon decision when the nerve was found evidently intact.

    Sleep paralysis is a relatively common but under-researched phenomenon. While the causes are unknown, a number of studies have investigated potential risk factors. In this article, we conducted a systematic review on the available literature regarding variables associated with both the frequency and intensity of sleep paralysis episodes. A total of 42 studies met the inclusion criteria. For each study, sample size, study site, sex and age of participants, sleep paralysis measure, and results ...

    PURPOSE: We describe the anaesthetic management of a patient with the autosomal dominant inherited disease, normokalaemic periodic paralysis. The disease results in intermittent bouts of limb and respiratory muscular weakness in association with hypothermia, stress, prolonged fasting or exercise. Unlike hypokalaemic and hyperkalaemic periodic paralysis, the more common variants of the disease, normokalaemic periodic paralysis is not accompanied by alterations in the plasma potassium concentration. CLINICAL FEATURES: A five-year-old boy presented for emergency scrotal exploration. He had a family history of periodic paralysis and had experienced previous episodes of weakness, two of which had required hospitalization for respiratory distress. On admission there was no evidence of weakness and serum potassium concentration was 4.2 mMol.L-1. A spinal anaesthetic was performed and the procedure was uncomplicated by muscle paralysis above the level of the spinal block. CONCLUSION: Avoidance of known precipitating factors and judicious use of neuromuscular blocking drugs has been advocated in patients with this disorder presenting for surgery. In appropriate circumstances, spinal anaesthesia represents a useful option in patients with normokalaemic periodic paralysis.

    One of the main goals of brain-machine interface (BMI) research is to restore function to people with paralysis. Currently, multiple BMI design features are being investigated, based on various input modalities (externally applied and surgically implantable sensors) and output modalities (e.g. control of computer systems, prosthetic arms, and functional electrical stimulation systems). While these technologies may eventually provide some level of benefit, they each carry associated burdens for end-users. We sought to assess the attitudes of people with paralysis toward using various technologies to achieve particular benefits, given the burdens currently associated with the use of each system. We designed and distributed a technology survey to determine the level of benefit necessary for people with tetraplegia due to spinal cord injury to consider using different technologies, given the burdens currently associated with them. The survey queried user preferences for 8 BMI technologies including electroencephalography, electrocorticography, and intracortical microelectrode arrays, as well as a commercially available eye tracking system for comparison. Participants used a 5-point scale to rate their likelihood to adopt these technologies for 13 potential control capabilities. Survey respondents were most likely to adopt BMI technology to restore some of their natural upper extremity function, including restoration of hand grasp and/or some degree of natural arm movement. High speed typing and control of a fast robot arm were also of interest to this population. Surgically implanted wireless technologies were twice as 'likely' to be adopted as their wired equivalents. Assessing end-user preferences is an essential prerequisite to the design and implementation of any assistive technology. The results of this survey suggest that people with tetraplegia would adopt an unobtrusive, autonomous BMI system for both restoration of upper extremity function and control of

    We describe a case of recurrent hysterical paralysis triggered by low back pain because of lumbar spondylolysis. A 16-year-old male soccer player was referred to our institution with five previous episodes of acute paralysis triggered by severe low back pain. We performed direct surgical repair of the terminal-stage bilateral spondylolysis at L4 using a hook-rod system. His chronic low back pain was completely resolved, and no further episodes of hysterical paralysis have occurred after surgery. Spine surgeons should be aware of possible hysterical conversion paralysis when there is discrepancy between radiological and neurological findings.

    Full Text Available BACKGROUND Hypokalaemic periodic paralysis is a rare disorder characterised by transient attacks of flaccid paralysis of varying intensity and frequency. Although mostly familial in aetiology, several sporadic cases with different causes have been reported. There are two groups of disorders predominantly that causes hypokalaemic paralysis. One group is due to transcellular shift of potassium and other is due to loss of potassium from body either through GI tract or through renal system. MATERIAL AND METHODS Here we report a study on the clinical and aetiological profile of 30 cases of hypokalaemic paralysis admitted in our institution between January 2014 to January 2016. RESULTS The aetiological workup of all the patients was done which revealed thyrotoxic periodic paralysis as the major cause in 12 of 30 patients. Three rare causes of hypokalaemia have been diagnosed which included Bartter’s syndrome, Mixed Connective tissue disorder, Sjogren’s syndrome. Vomiting and diarrhoea was seen in 12 of 30 patients. CONCLUSION Hypokalaemic periodic paralysis is a heterogenous group of disorder. A significant number of patients had thyroid disorders mostly in the form of thyrotoxicosis, non-renal and renal loss of potassium like diarrhoea and vomiting. Early recognition and prompt management of these conditions is essential to prevent residual deformity and further attacks in future.

    To clarify the time course of recovery in patients with idiopathic vocal fold paralysis. Retrospective chart review. Medical records for all patients with idiopathic vocal fold paralysis over a 10-year period were reviewed to obtain demographic and clinical information, including onset of disease and recovery of vocal function. Stroboscopic exams of patients who recovered voice were reviewed blindly to assess return of vocal fold motion. Thirty-eight of 55 patients (69%) recovered vocal function. Time course of recovery could be assessed in 34 patients who did not undergo injection augmentation. The mean time to recovery was 152.8 ± 109.3 days (left, 179.8 ± 111.3 days; right, 105.3 ± 93.7 days; P = .088). Two-thirds of patients recovered within 6 months. Probability of recovery declined over time. Five of 22 patients who recovered voice had return of vocal fold motion; 17 did not. The mean time to recovery did not differ between these groups (return of motion, 127.4 ± 132.3 days; no return of motion, 160.1 ± 105.1 days; P = .290). Sixty-nine percent of patients with idiopathic vocal fold paralysis recovered vocal function, two-thirds doing so within 6 months of onset. Age, gender, laterality, use of injection augmentation did not influence recovery rate. Declining probability of recovery over time leads us to consider framework surgery after 6 months in patients with idiopathic paralysis. 4.

    2014-12-01

    Osteological changes consistent with neurogenic paralysis were observed in one male and one female skeleton recovered from two Croatian medieval sites - Virje and Zadar. Both skeletons display limb asymmetry typical of neurogenic paralysis that occurs during the childhood. The male skeleton displays atrophy and shortening of the right arm and the right femur, while the female skeleton exhibits identical changes on the right arm and both legs. Additionally, both skeletons exhibit scoliotic changes of the spine, and the female skeleton also displays bilateral hip dysplasia. Differential diagnosis included disorders such as cerebral palsy, poliomyelitis, cerebrovascular accident, and Rasmussen's encephalitis. These are the first cases of neurogenic paralysis (cerebral palsy and/or paralytic poliomyelitis) identified in Croatian archeological series. The Virje skeleton is only the third case of hemiplegia identified from archeological contexts (first with spinal scoliosis), while the Zadar skeleton represents the first case of triplegia reported in the paleopathological literature.

    Clinicians and patients benefit when they have a clear understanding of how medical conditions influence patients' life experiences. Patients' perspectives on life with unilateral vocal fold paralysis have not been well described. To promote patient-centered care by characterizing the patient experiences of living with unilateral vocal fold paralysis. This study used mixed methods: surveys using the voice and dysphagia handicap indexes (VHI and DHI) and semistructured interviews with adults with unilateral vocal cord paralysis recruited from a tertiary voice center. Recorded interviews were transcribed, coded using a hierarchical coding system, and analyzed using an iterative inductive-deductive approach. Symptom domains of the patient experience. In 36 patients (26 [72%] were female, and the median age and interquartile range [IQR] were 63 years [48-68 years]; median interview duration, 42 minutes), median VHI and DHI scores were 96 (IQR, 77-108) and 55.5 (IQR, 35-89) at the time of interviews, respectively. Frustration, isolation, fear, and altered self-identity were primary themes permeating patients' experiences. Frustrations related to limitations in communication, employment, and the medical system. Sources of fear included a loss of control, fear of further dysfunction or permanent disability, concern for health consequences (eg, aspiration pneumonia), and/or an inability to call for help in emergency situations. These experiences were modified by the following factors: resilience, self-efficacy, perceived sense of control, and social support systems. Effects of unilateral vocal fold paralysis extend beyond impaired voice and other somatic symptoms. Awareness of the extent to which these patients experience frustration, isolation, fear, and altered self-identity is important. A patient-centered approach to optimizing unilateral vocal fold paralysis treatment is enhanced by an understanding of both the physical dimension of this condition and how patients

    Full Text Available Objective: There is paucity of reports on thyrotoxic periodic paralysis (TPP from India. We report the patients with TPP and compare them with idiopathic hypokalemic periodic paralysis (IHPP. Materials and Methods: Patients with hypokalemic periodic paralysis (HPP treated during the past 11 years were evaluated retrospectively. Their demographic parameters, family history, clinical features, precipitating factors, severity of weakness, laboratory parameters and rapidity of recovery were recorded. The demographic, clinical and laboratory parameters of TPP and IHPP were compared. Results: During the study period, we managed 52 patients with HPP; nine (17.3% of whom had TPP and 27 (52% had IHPP. The demographic, precipitating factors, number of attacks and severity of limb weakness were similar between the TPP and IHPP groups, except in the IHPP group, bulbar weakness was present in four and respiratory paralysis in six, needing artificial ventilation in two patients. Serum potassium was significantly lower in TPP (2.21 ± 0.49 compared with IHPP (2.67 ± 0.59, P = 0.04. Four patients with TPP had subclinical thyrotoxicosis and two had subclinical hyperthyroidism. Rebound hyperkalemia occurred in both TPP and IHPP (three versus eight patients. The recovery was faster in IHPP (26.7 ± 15.4 h compared with TPP (34.0 ± 14.0 h, but was statistically insignificant. Conclusion: TPP constitutes 17.3% of HPP, and absence of clinical features of thyrotoxicosis and subclinical hyperthyroidism in TPP is not uncommon. Clinical features, demographic profile and rebound hyperkalemia are similar in both TPP and IHPP. The serum potassium level is significantly low in the TPP compared with the IHPP group.

    Full Text Available Laryngeal paralysis is the effect of an inability to abduct the arytenoid cartilages duringinspiration, resulting in respiratory signs consistent with partial airway obstruction. Theaetiology of the disease can be congenital (hereditary laryngeal paralysis or congenitalpolyneuropathy, or acquired (trauma, neoplasia, polyneuropathy, endocrinopathy. Themost common form of acquired laryngeal paralysis (LP is typically seen in old, large breeddogs and is a clinical manifestation of a generalised peripheral polyneuropathy recentlyreferred to as geriatric onset laryngeal paralysis polyneuropathy. Diagnosing LP based onclinical signs, breed and history has a very high sensitivity (90% and can be confirmed bylaryngeal inspection. Prognosis after surgical correction depends on the aetiology: traumaticcases have a good prognosis, whereas tumour-induced or polyneuropathy-induced LP has aguarded prognosis. Acquired idiopathic LP is a slow progressive disease, with dogs reachingmedian survival times of 3–5 years after surgical correction.

    Thyrotoxic periodic paralysis (TPP) is an endocrine disorder presenting with proximal motor weakness, typically greatest in the lower extremities, hypokalemia, and signs or laboratory findings consistent with hyperthyroidism. The incidence of TPP is highest in Asian males. This is a case report of a 30-year-old male active duty Soldier who presented to the emergency department complaining of several recent episodes of lower extremity paralysis. The patient underwent a workup which included serum and cerebrospinal fluid studies, and was found to be hypokalemic and hyperthyroid. Following consultation with neurology, the patient was admitted to the medicine service and treated for thyrotoxic periodic paralysis with potassium replacement and treatment of his hyperthyroidism. Since achieving a euthyroid state, he has had no recurrences of TPP. This disease should be considered in patients presenting with symmetric motor weakness and hypokalemia, whether or not symptoms of hyperthyroidism are elicited during the review of systems.

    To assess the psychological distress, the ways of coping with that stress, and the self-esteem of patients with facial paralysis after acoustic neuroma surgery. Possible predictors and associations between these measures were also explored. Four validated questionnaires were completed by patients with facial paralysis after acoustic neuroma surgery: 1) the Derriford Appearance Scale (DAS) to measure psychological distress, 2) the COPE questionnaire to measure how patients cope with facial paralysis, 3) the Personal Report questionnaire to measure the self-esteem of patients, and 4) the Facial Paralysis Questionnaire (FPQ) to measure the severity of facial paralysis. One hundred three patients with facial paralysis after surgical removal of acoustic tumors. Distress spanned a wide range in these patients. There was no statistically significant association between the level of distress and the grade of facial paralysis or between time since operation and levels of distress. Women had higher levels of distress (P = .02) and a significant negative correlation was found between levels of distress and age (r = -0.28, P = .005). High levels of distress were associated with low levels of self-esteem, as shown by the significant negative correlation between level of distress and self-esteem (r = -0.59, P = .01). A significant correlation between distress and maladaptive coping (r = 0.31, P = .002) was also found. Stepwise multiple regression of the distress scores revealed that self-esteem was the most important contributing factor (standardized coefficient beta -0.60, P = .0001), followed by age (beta -0.24, P = .006) and sex (beta -0.21, P = .04). This model explained 44% of the distress variance. Clinicians must be aware of the distress felt by some patients experiencing facial palsy after acoustic neuroma surgery and that the level of distress may not be related to the clinical grade of the facial nerve paralysis. People with low self-esteem, young people, and women

    Treatment options for symptomatic unilateral vocal fold paralysis (VFP) include vocal fold augmentation, laryngeal framework surgery, and laryngeal reinnervation. Laryngeal reinnervation (LR) has been suggested to provide "tone" to the paralyzed VF. This implies a loss of tone as a result of denervation without reinnervation. We performed laryngeal electromyography (LEMG) in patients with chronic VFP to understand the innervation status associated with a chronically paralyzed vocal fold. Retrospective review of LEMG data in adult patients with chronic VFP from January 2009 to December 2014. LEMG was performed at least 6 months after-onset of VFP. Qualitative LEMG, quantitative LEMG, and adductory synkinesis testing were performed, and the parameters were collected. Twenty-seven vocal folds were studied (23 unilateral VFP and 2 bilateral VFP). Average age was 59 ± 17 years. The median duration from recurrent laryngeal nerve injury to LEMG was 8.5 months (range 6-90 months). The majority of patients, 24 of 27 (89%), had motor unit potentials during phonation tasks on LEMG, and only 3 of 27 (11%) patients were electrically silent. Quantitative LEMG showed 287.8 mean turns per second (normal ≥ 400). Motor unit configuration was normal in 12 of 27 (44%), polyphasic in 12 of 27 (44%), and absent in the electrically silent patients. Adductory synkinesis was found in 6 of 20 (30%) patients. Chronic vocal fold paralysis is infrequently associated with absent motor-unit recruitment, indicating some degree of preserved innervation and/or reinnervation in these patients. LEMG should be part of the routine workup for chronic VFP prior to consideration of LR. 4. Laryngoscope, 2018. © 2018 The American Laryngological, Rhinological and Otological Society, Inc.

    2009-01-01

    Idiopathic diaphragm paralysis is probably more common and responsible for more morbidity than generally appreciated. Bell's palsy, or idiopathic paralysis of the seventh cranial nerve, may be seen as an analogous condition. The roles of zoster sine herpete and herpes simplex have increasingly been recognized in Bell's palsy, and there are some data to suggest that antiviral therapy is a useful adjunct to steroid therapy. Thus, we postulated that antiviral therapy might have a positive impact on the course of acute idiopathic diaphragm paralysis which is likely related to viral infection. Three consecutive patients with subacute onset of symptomatic idiopathic hemidiaphragm paralysis were empirically treated with valacyclovir, 1,000 mg twice daily for 1 week. Prior to therapy, diaphragmatic function was assessed via pulmonary function testing and two-dimensional B-mode ultrasound, with testing repeated 1 month later. Diaphragmatic function pre- and post-treatment was compared to that of a historical control group of 16 untreated patients. All three subjects demonstrated ultrasound recovery of diaphragm function 4-6 weeks following treatment with valacyclovir. This recovery was accompanied by improvements in maximum inspiratory pressure (PI(max)) and vital capacity (VC). In contrast, in the untreated cohort, diaphragm recovery occurred in only 11 subjects, taking an average of 14.9 +/- 6.1 months (mean +/- SD). The results of this small, preliminary study suggest that antiviral therapy with valacyclovir may be helpful in the treatment of idiopathic diaphragm paralysis induced by a viral infection.

    2016-10-01

    Phrenic paralysis is a known complication of central venous catheterization, but it is not listed as a complication related to cardiac implantable electronic device (CIED) implants. The aim of this study is to describe the incidence, causes, clinical picture, and management of phrenic paralysis occurring in this scenario. We retrospectively analysed data from our CIED implantation database and identified those patients who suffered phrenic paralysis during the implantation procedure. Four of 891 patients (subclavian puncture in 626) developed phrenic paralysis during pacemaker or defibrillator implant procedures. Severe respiratory failure needing ventilatory support occurred in two, being the phrenic paralysis transient in all of the cases. Transient phrenic paralysis may occur during CIED implantation probably related to the infiltration of local anaesthesia in the subclavian area. Mechanism, prevention, and management are discussed.

    K. H. D. Thilini Hemachandra

    2018-01-01

    Full Text Available Background. Acute flaccid paralysis is an uncommon, but potentially life threatening, sequel of severe hyperkalemia. Reported primary aetiologies include renal failure, Addison’s disease, potassium sparing diuretics, potassium supplements, and dietary excess. Coconut water, when consumed in excess, has been reported to cause severe hyperkalemia. We report the case of acute ascending flaccid paralysis secondary to hyperkalemia induced by multiple trigger factors—king coconut water, renal failure, diabetes, metabolic acidosis, and potassium sparing diuretics. Case Presentation. A 78-year-old man presented with acute ascending type flaccid paralysis over five-hour duration and subsequently developed preterminal cardiac arrhythmias secondary to severe hyperkalemia (serum potassium: 7.02 mEq/L. He was on Losartan and Spironolactone for ischemic heart disease. Dietary history revealed excessive intake of king coconut water (Cocos nucifera over past one week. Electrocardiogram returned to normal rhythm and serum potassium was 6.1 mEq/L within 2 hours of institution of emergency management for life threatening hyperkalemia. Neurological symptoms completely recovered within twenty-four hours without the need for dialysis. Electromyogram three days after the initial presentation revealed normal findings. Conclusions. The report describes a rare case of secondary hyperkalemic flaccid paralysis induced by multiple trigger factors. It is important that patients with risk factors for hyperkalemia are educated regarding avoiding excess dietary potassium. Regular follow-up of these patients is mandatory with review of medication related side effects and serum electrolytes.

    We describe a 37-year-old man with a 4-month history of episodic muscular weakness, involving mainly lower-limbs. Hypokalemia was documented in one episode and managed with intravenous potassium chloride. Hyperthyroidism was diagnosed 4 months after onset of attacks because of mild symptoms. The patient was subsequently diagnosed as having thyrotoxic periodic paralysis associated with Graves' disease. Treatment with propranolol and methimazol was initiated and one year later he remains euthyroid and symptom free. Thyrotoxic periodic paralysis is a rare disorder, especially among Caucasians, but it should always be considered in patients with acute paralysis and hypokalemia, and thyroid function should be evaluated.

    2009-08-01

    Facial synkinesis (or synkinesia) (FS) occurs frequently after paresis or paralysis of the facial nerve and is in most cases due to aberrant regeneration of (branches of) the facial nerve. Patients suffer from inappropriate and involuntary synchronous facial muscle contractions. Here we describe two cases of sound-induced facial synkinesis (SFS) after facial nerve injury. As far as we know, this phenomenon has not been described in the English literature before. Patient A presented with right hemifacial palsy after lesion of the facial nerve due to skull base fracture. He reported involuntary muscle activity at the right corner of the mouth, specifically on hearing ringing keys. Patient B suffered from left hemifacial palsy following otitis media and developed involuntary muscle contraction in the facial musculature specifically on hearing clapping hands or a trumpet sound. Both patients were evaluated by means of video, audio and EMG analysis. Possible mechanisms in the pathophysiology of SFS are postulated and therapeutic options are discussed.

    Vocal cord paralysis is a common cause of hoarseness. It may be secondary to many types of lesions along the cranial nerve X pathway and its branches, particularly the laryngeal recurrent nerves. Despite the idiopathic nature of a great number of cases, imaging methods play a very significant role in the investigation of etiologic factors, such as thyroid and esophagus neoplasias with secondary invasion of the laryngeal recurrent nerves. Other conditions such as aortic and right subclavian artery aneurysms also may be found. The knowledge of local anatomy and related diseases is of great importance for the radiologist, so that he can tailor the examination properly to allow an appropriate diagnosis and therapy planning. Additionally, considering that up to 35% of patients with vocal cord paralysis are asymptomatic, the recognition of radiological findings indicative of this condition is essential for the radiologist who must warn the referring physician on the imaging findings. In the present study, the authors review the anatomy and main diseases related to vocal cord paralysis, demonstrating them through typical cases evaluated by computed tomography and magnetic resonance imaging, besides describing radiological findings of laryngeal abnormalities indicative of this condition.

    Acute flaccid paralysis (AFP) can be caused by a number of conditions. A common preventable cause is poliomyelitis which is still being reported in Pakistan, Guillain Barre Syndrome (GBS), also known as Acute Inflammatory Demyelinating Polyneuropathy, is another common cause of acute flaccid paralysis. It is important to recognize GBS in childhood as parents consider all acute flaccid paralysis to be due to poliomyelitis. The present study was designed to know the frequency of different causes of acute flaccid paralysis in Hazara division. This is a retrospective analysis of cases of acute flaccid paralysis reported from various districts of Hazara division during the period January 2003 to December 2004. Acute flaccid paralysis was diagnosed clinically through history and clinical examination. The underlying cause of acute flaccid paralysis was investigated by appropriate laboratory tests, such as serum electrolytes, cerebrospinal fluid analysis, electromyogram, nerve conduction study and stool culture for polio virus and other enteroviruses. Diagnosis of Poliomyelitis was confirmed by stool testing for poliovirus. 74 patients presented with AFP during the study period. 36 were male and 38 were female. Guillain Barre syndrome and enteroviral encephalopathy were the two leading causes of acute flaccid paralysis. Majority of the cases were reported from Mansehra district. Children of age groups 12 to 24 months and > 96 months constituted the majority (20% each). Guillian Barre syndrome was the leading cause of acute flaccid paralysis reported from various parts of Hazara division.

    Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

    Thyrotoxic periodic paralysis is a potentially fatal complication of hyperthyroidism, more common in Asian races, which is defined by a massive intracellular flux of potassium. This leads to profound hypokalaemia and muscle paralysis. Although the paralysis is temporary, it may be lethal if not diagnosed and treated rapidly, as profound hypokalaemia may induce respiratory muscle paralysis or cardiac arrest. The condition is often misdiagnosed in the west due to its comparative rarity in Caucasians; however it is now increasingly described in Caucasians and is also being seen with increasing frequency in western hospitals due to increasing immigration and population mobility. Here we describe the case of a patient with panhypopituitarism due to a craniopharyngioma, who developed thyrotoxic periodic paralysis due to excessive L-thyroxine replacement. This disorder has been described in Asian subjects but, to our knowledge, thyrotoxic periodic paralysis secondary to excessive L-thyroxine replacement has never been described in Caucasians.

    To evaluate the use of CT in patients with vocal cord paralysis due to extralaryngeal causes, and to use CT for the assessment of extralaryngeal diseases causing vocal cord paralysis. We prospectively studied the results of CT in 41 patients with vocal cord paralysis in whom laryngoscopy revealed no laryngeal cause and physical examination demonstrated no definite extralaryngeal cause. The extralaryngeal cause of vocal cord palsy was determined after comprehensive clinical diagnosis. Enhanced CT scans were acquired from the skull base and continued to the level of the aorticopulmonary window. We used CT to assess the detection rate for extralaryngeal causes and to extimate the extent of extralaryngeal disease and the distribution of lesions. CT revealed that in 20 of 41 patients(49%) the extralarygeal causes of vocal paralysis were as follows : thyroid cancer(n=10), nodal disease(n=6), esophageal cancer(n=2), neurogenic tumor(n=1), aortic aneurysm(n=1). Lesions were located on the left side in 13 patients(65%), and in the tracheoesophageal groove in 15(75%). In patients with vocal cord paralysis in whom no definite lesion is seen on physical examination , CT could be a useful primary imaging method for the assessment of extralaryngeal causes

    Facial paralysis is a devastating condition that may cause severe cosmetic and functional deformities. In this study we describe our technique for superficial muscular aponeurotic system (SMAS) suspension using barbed suture and compare the vectors of suspension in relation to the underlying musculature. This study also quantifies the improvements in postoperative symmetry using traditional anthropologic landmarks. The efficacy of this procedure for improving facial paralysis was determined by comparing anthropometric indices and using Procrustes distance between 4 groupings of homologous landmarks plotted on each patient's preoperative and postoperative photos. Geometric morphometrics was used to evaluate change in facial shape and improvement in symmetry postoperatively.To analyze the vector of suspension in relation to the underlying musculature, specific anthropologic landmarks were used to calculate the vector of the musculature in 3 facial hemispheres from cadaveric controls against the vector of repair in our patients. Ten patients were included in our study. Subjectively, great improvement in functional status was achieved. Geometric morphometric analysis demonstrated a statistically significant improvement in facial symmetry. Cadaveric dissection demonstrated that the suture should be placed in the SMAS in vectors parallel to the underlying musculature to achieve these results. There were no complications in our study to date. In conclusion, multivectored SMAS suture suspension is an effective method for restoring static suspension of the face after facial paralysis. This method has the benefit of producing quick, reliable results with improved function, low cost, and low morbidity.

    2015-12-01

    Incomplete facial paralysis occurs in about a third of patients with Bell's palsy. Although their faces are symmetrical at rest, when they smile they have varying degrees of disfigurement. Currently, cross-face nerve grafting is one of the most useful techniques for reanimation. Transfer of the masseteric nerve, although widely used for complete paralysis, has not to our knowledge been reported for incomplete palsy. Between December 2008 and November 2013, we reanimated the faces of 9 patients (2 men and 7 women) with incomplete unilateral facial paralysis with transposition of the masseteric nerve. Sex, age at operation, cause of paralysis, duration of denervation, recipient nerves used, and duration of follow-up were recorded. Commissural excursion, velocity, and patients' satisfaction were evaluated with the FACIAL CLIMA and a questionnaire, respectively. The mean (SD) age at operation was 39 (±6) years and the duration of denervation was 29 (±19) months. There were no complications that required further intervention. Duration of follow-up ranged from 6-26 months. FACIAL CLIMA showed improvement in both commissural excursion and velocity of more than two thirds in 6 patients, more than one half in 2 patients and less than one half in one. Qualitative evaluation showed a slight or pronounced improvement in 7/9 patients. The masseteric nerve is a reliable alternative for reanimation of the smile in patients with incomplete facial paralysis. Its main advantages include its consistent anatomy, a one-stage operation, and low morbidity at the donor site. Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons.

    Vocal cord paralysis after tracheal intubation is rare. It causes severe hoarseness and aspiration, and delays recovery and discharge. Arytenoid cartilage dislocation and recurrent nerve paralysis are main causes of vocal cord paralysis. Physical stimulation of the tracheal tube as well as patient and surgical characteristics also contribute. Vocal cord paralysis occurs in 1 (0.07%) of 1,500 general surgery patients and on the left side in 70% of cases. It is associated with surgery/anesthesia time (two-fold, 3-6 hours; 15-fold, over 6 hours), age (three-fold, over 50 years), and diabetes mellitus or hypertension (two-fold). Symptoms resolve in 2-3 months. In adult cardiovascular surgery, vocal cord paralysis occurs in 1 (0.7-2%) of 50-100 cardiac surgery patients and 1 (8.6-32%) of 3-10 thoracic aortic surgery patients. In pediatric cardiac surgery, vocal cord paralysis occurs in 1 (0.1-0.5%) of 200-1,000 patients. We classified the severity of vocal cord paralysis as I, severe hoarseness; II, aspiration or dysphagia; and III, bilateral vocal cord paralysis, aspiration pneumonia, or the need for tracheal re-intubation or tracheotomy. We discuss the importance of informed consent for the patient and family.

    To report a new technique for unilateral brow suspension for facial paralysis that is minimally invasive, limits supraciliary scar formation, does not require specialized endoscopic equipment or expertise, and has proved to be equal to direct brow suspension in durability and symmetry. Retrospective survey of a case series of 23 patients between January 1997 and December 2000. Metropolitan tertiary care center. Patients with head and neck tumors and brow ptosis caused by facial nerve paralysis. The results of the procedure were determined using the following 3-tier rating system: outstanding (excellent elevation and symmetry); acceptable (good elevation and fair symmetry); and unacceptable (loss of elevation). The results were considered outstanding in 12 patients, acceptable in 9 patients, and unacceptable in only 1 patient. One patient developed a hematoma, and 1 patient required a secondary adjustment. The technique has proved to be superior to standard brow suspension procedures with regard to scar formation and equal with respect to facial symmetry and suspension. These results have caused us to abandon direct brow suspension and to use this minimally invasive method in all cases of brow ptosis due to facial paralysis.

    Peripheral facial nerve paralysis in children might be an alarming sign of serious disease such as malignancy, systemic disease, congenital anomalies, trauma, infection, middle ear surgery, and hypertension. The cases of 40 consecutive children and adolescents who were diagnosed with peripheral facial nerve paralysis at Baskent University Adana Hospital Pediatrics and Pediatric Neurology Unit between January 2010 and January 2013 were retrospectively evaluated. We determined that the most common cause was Bell palsy, followed by infection, tumor lesion, and suspected chemotherapy toxicity. We noted that younger patients had generally poorer outcome than older patients regardless of disease etiology. Peripheral facial nerve paralysis has been reported in many countries in America and Europe; however, knowledge about its clinical features, microbiology, neuroimaging, and treatment in Turkey is incomplete. The present study demonstrated that Bell palsy and infection were the most common etiologies of peripheral facial nerve paralysis. © The Author(s) 2014.

    2004-12-01

    Thyrotoxic hypokalemic periodic paralysis (THypoKPP) is an uncommon disorder with an unknown etiology. We describe a family in which the proband presented with paralysis and thyrotoxicosis. Because of similarities between familial hypokalemic periodic paralysis (FHypoKPP) and THypoKPP, we sequenced exon 12 of the SCN4A gene, which is known to be mutated in FHypoKPP. We identified an Arg672Ser mutation in the proband and his affected father, as well as the proband's brother. As the brother has paralysis without thyrotoxicosis, our finding suggests that the genetic spectrum of FHypoKPP and THypoKPP overlap. We speculate that thyroid hormone may exert a threshold or permissive effect in hypokalemic periodic paralysis. Non-thyrotoxic family members of individuals with THypoKPP may have an unrecognized risk for paralysis.

    A retrospective review. The purpose of this study was to investigate the clinical outcomes in adolescents diagnosed with psychogenic low-back pain and hysterical paralysis and to evaluate the efficacy of differential diagnosis methods. The incidence of low-back pain in adolescence is similar to that in adults, but the causes of low-back pain are difficult to determine in most cases. For these patients, a definitive diagnosis of psychogenic low-back pain and hysterical paralysis as well as adequate treatment are clinically important to avoid unnecessary surgical treatment. Eleven patients (3 males and 8 females; mean age, 16.5 years; range, 13-19 y) diagnosed with psychogenic low-back pain and hysterical paralysis were followed up for 2-10.25 years (mean, 4.67 y). Nonorganic signs were observed in almost all patients. For the purpose of excluding organic disorders, the thiopentone pain study was used in patients who complained mainly of pain, and motor evoked potentials using transcranial magnetic stimulation were measured in patients experiencing primarily muscle weakness. The psychiatric diagnosis was neurosis in 9 patients, whereas it was psychosomatic disorder in 2 patients. Conservative treatment, such as physiotherapy, was performed, and at the final follow-up evaluation, outcomes were regarded as excellent in 7 patients and good in 4 patients. The prognosis of psychogenic low-back pain and hysterical paralysis in adolescence is relatively good. However, it is important to understand the characteristics of psychogenic low-back pain and hysterical paralysis in childhood and young adulthood and to perform accurate diagnosis by screening for nonorganic signs and excluding organic disorders by using the thiopentone pain study and motor evoked potentials obtained using transcranial magnetic stimulation.

    Conclusions: H to Q transfer in the presence of quadriceps paralysis with good power in hamstring is a better alternative than supracondylar osteotomy because it is a dynamic correction and it produces some degree of recurvatum with increasing stability of knee in extension while walking. While inserting hamstring over patella the periosteum is not cut in an I-shaped fashion to create a flap which gives additional strength to new insertion and also patella act as a fulcrum during the extension of knee by producing the bowstring effect.

    The human nervous system is a vast network carrying not only sensory and movement information, but also information to and from our organs, intimately linking it to our overall health. Scientists and engineers have been working for decades to tap into this network and 'crack the neural code' by decoding neural signals and learning how to 'speak' the language of the nervous system. Progress has been made in developing neural decoding methods to decipher brain activity and bioelectronic technologies to treat rheumatoid arthritis, paralysis, epilepsy and for diagnosing brain-related diseases such as Parkinson's and Alzheimer's disease. In a recent first-in-human study involving paralysis, a paralysed male study participant regained movement in his hand, years after his injury, through the use of a bioelectronic neural bypass. This work combined neural decoding and neurostimulation methods to translate and re-route signals around damaged neural pathways within the central nervous system. By extending these methods to decipher neural messages in the peripheral nervous system, status information from our bodily functions and specific organs could be gained. This, one day, could allow real-time diagnostics to be performed to give us a deeper insight into a patient's condition, or potentially even predict disease or allow early diagnosis. The future of bioelectronic medicine is extremely bright and is wide open as new diagnostic and treatment options are developed for patients around the world. © 2017 The Association for the Publication of the Journal of Internal Medicine.

    1999-12-01

    The Waterloo Sleep Experiences Scale was developed to assess the prevalence of sleep paralysis and a variety of associated hypnagogic and hypnopompic hallucinoid experiences: sensed presence, felt pressure, floating sensations, auditory and visual hallucinations, and fear. Consistent with results of recent surveys, almost 30% of 870 university students reported at least one experience of sleep paralysis. Approximately three-quarters of those also reported at least one hallucinoid experience, and slightly more than 10% experienced three or more. Fear was positively associated with hallucinoid experiences, most clearly with sensed presence. Regression analyses lend support to the hypothesis that sensed presence and fear are primitive associates of sleep paralysis and contribute to the elaboration of further hallucinoid experiences, especially those involving visual experiences.

    Thyrotoxic hypokalemic periodic paralysis (THPP) is a medical emergency characterized by acute attacks of weakness, hypokalemia, and thyrotoxicosis that resolve with the treatment of hyperthyroidism. Attacks are transient, self-limited, associated with hypokalemia and resemble those of familial hypokalemic periodic paralysis (FHPP), an autosomal dominant neurological channelopathy. This study reviews the clinical features and genetic findings of THPP in 25 Brazilian patients. Most patients had weight loss, taquicardia, goiter, tremor, and ophthalmopathy. Most often attacks arose during the night and recovered spontaneously but some patients evolved to total quadriplegia, and few experienced cardiac arrhythmias. All patients had suppressed TSH and elevated T4 and most had positive anti-thyroid antibodies, indicating autoimmunity thyrotoxic etiology. Potassium was low in all patients during the crisis. Prophylactic potassium therapy has not been shown to prevent attacks; however it was useful for curbing the paralysis during the crisis. We identified the mutation R83H in the KCNE3 gene in one sporadic case, and M58V in the KCNE4 gene in one case with family history. Furthermore, we identified other genetic polymorphisms in the CACNA1S, SCN4A, KCNE1, KCNE2, KCNE1L, KCNJ2, KCNJ8 e KCNJ11 genes. We conclude that THPP is the most common treatable cause of acquired periodic paralysis; therefore, it must be included in the differential diagnosis of acute muscle weakness.

    The objective of this study was to report the first case of unilateral vocal fold paralysis in a patient with Parkinson disease (PD) and to review the literature. This is a case report and literature review following PubMed search using the keywords "Parkinson," "vocal fold paralysis," "vocal fold palsy," "vocal fold immobility," "vocal fold adductor palsy," "airway obstruction," and "stridor." A total of 18 subjects diagnosed with PD and vocal fold paralysis were described. In all cases, the vocal fold paralysis was bilateral and the main presenting symptoms were stridor and shortness of breath necessitating intubation and tracheostomy. This article describes the first case of PD presenting with dysphonia secondary to unilateral vocal fold paralysis (left). The management consisted of injection laryngoplasty for medialization of the paralyzed vocal fold. Patients with PD can present with unilateral vocal fold paralysis. Early treatment is advocated in view of the advent of injection laryngoplasty as a safe office procedure. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Occasionally, malignant neoplasms may cause peripheral facial nerve paralysis as a presenting symptom. A 63-year-old man was referred to the Emergency Department because of a peripheral facial nerve paralysis, lasting for 10 days. Initial diagnostic examinations revealed no apparent cause for this facial nerve paralysis. Chest X-ray, however, showed a suspicious tumoural mass, located in the right hilar region, as confirmed by CAT scan. The diagnosis of an advanced stage lung adenocarcinoma was finally confirmed by bronchial biopsy. MRI scanning showed diffuse brain metastases and revealed a pontine lesion as the most probable underlying cause of this case of peripheral facial nerve paralysis. Platin-based palliative chemotherapy was given, after an initial pancranial irradiation. According to the MRI findings, the pontine lesion was responsible for the peripheral facial nerve paralysis, as an initial presenting symptom in this case of lung adenocarcinoma. This clinical case of a peripheral facial nerve paralysis was caused by a pontine brain metastasis and illustrates a rather rare presenting symptom of metastatic lung cancer.

  11. Practical aspects in the management of hypokalemic periodic paralysis

    2008-04-01

    Full Text Available Abstract Management considerations in hypokalemic periodic paralysis include accurate diagnosis, potassium dosage for acute attacks, choice of diuretic for prophylaxis, identification of triggers, creating a safe physical environment, peri-operative measures, and issues in pregnancy. A positive genetic test in the context of symptoms is the gold standard for diagnosis. Potassium chloride is the favored potassium salt given at 0.5–1.0 mEq/kg for acute attacks. The oral route is favored, but if necessary, a mannitol solvent can be used for intravenous administration. Avoidance of or potassium prophylaxis for common triggers, such as rest after exercise, high carbohydrate meals, and sodium, can prevent attacks. Chronically, acetazolamide, dichlorphenamide, or potassium-sparing diuretics decrease attack frequency and severity but are of little value acutely. Potassium, water, and a telephone should always be at a patient's bedside, regardless of the presence of weakness. Perioperatively, the patient's clinical status should be checked frequently. Firm data on the management of periodic paralysis during pregnancy is lacking. Patient support can be found at http://www.periodicparalysis.org.

    The purpose of this study was to document the 30-year experience of the authors' center in the management of developmental facial paralysis and to analyze the outcomes of microsurgical reconstruction. Forty-two cases of developmental facial paralysis were identified in a retrospective clinical review (1980 to 2010); 34 (80.95 percent) were children (age, 8 ± 6 years) and eight (19.05 percent) were adults (age, 27 ± 12 years). Comparisons between preoperative and postoperative results were performed with electrophysiologic studies and video evaluations by three independent observers. Mean follow-up was 8 ± 6.3 years (range, 1 to 23 years). Overall, outcome scores improved in all of the patients, as was evident from the observers' mean scores (preoperatively, 2.44; 2 years postoperatively, 3.66; final, 4.11; p children as compared with adults (p children with developmental facial paralysis and reduces the prevalence of aesthetic and functional sequelae of the condition, thus facilitating reintegration among their peers. The experience of this center should serve as a framework for the establishment of accurate and reliable guidelines that will facilitate early diagnosis and management of developmental facial paralysis and provide support and counseling to the family.

    Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis. Copyright © 2015 Elsevier Masson SAS.

    Conservative management of idiopathic or herpetic acute peripheral facial palsy (herpes zoster oticus, HZO) often leads to a favorable outcome. However, recent multicenter studies have challenged the necessity of antivirals. Whereas large numbers of patients are required to reveal statistical differences in a disease with an overall positive outcome, surprisingly few studies differentiate between patients with paresis and paralysis. Analyzing our own prospective cohort of patients and reviewing the current literature on conservative treatment of Bell's palsy and HZO, we reveal the importance of initial baseline assessment of the disease course to predict the outcome and to validate the impact of medical treatment options. STUDY DESIGN AND DATA SOURCE: Prospective analysis of consecutive patients referred to 2 tertiary referral centers and research on the Cochrane Library for current updates of their previous reviews and search of MEDLINE (1976-2009) for randomized trials on conservative treatment of acute facial palsy were conducted. One hundred ninety-six patients with Bell's palsy or HZO were followed up prospectively until complete recovery or at least for 12 months. The numeric Fisch score (FS) was used to classify facial function, and patients were separated between incomplete palsy (=paresis) and complete paralysis. Electroneuronography (ENoG) was used to further subdivide patients with paralysis. The treatment protocol was independent of the ongoing investigation including prednisone and valacyclovir in most patients. A total of 250 previous studies on facial palsy outcome were evaluated regarding their distinction between different severity scores at baseline and its impact on treatment outcome. Trials not making the distinction between paresis and paralysis at baseline and with an insufficient follow-up of less than 12 months were excluded. In the Bell's and HZO paresis group, all except 1 patient recovered completely, most of them within 3 months

    Paralysis due to hypokalemia results from an acute shift of potassium into cells or excessive potassium deficit. In the absence of potassium deficit, it is observed in Familial Hypokalemic Periodic Paralysis and in Thyrotoxic Hypokalemic Periodic Paralysis (TPP). This report describes the initial presentation of hyperthyroidism as sudden quadriplegia associated with hypokalemia. A healthy 25-year-old Puerto Rican policeman came to the emergency room with sudden paralysis in the four extremities of five hours evolution. He woke up in the morning and could not get up. The day before admission his legs felt weak, and it was hard to get out of bed. He arrived home at 7:00 PM, ate pasta and vegetables, and went to sleep at 10:00 PM. He had no diarrhea or weight loss, no history of medications or illicit drugs. He has a cousin and an aunt with the diagnosis of hypo-thyroidism. The admission temperature was 36.0 degrees C, pulse 96 per minute, respiratory rate 18 per minute, blood pressure 160/70 mmHg. He was alert and oriented as to time, place and person. He could talk properly and was in no respiratory distress. He had no exophtalmos or lid lag. The thyroid was not enlarged or tender. No pseudoclubbing or pretibial edema was found. There was flaccid paralysis of all extremities, 0/5 legs and 1/5 arms. Deep tendon reflexes could not be elicited. The cranial nerves and sensory examination were normal. The hemogram was within normal limits as were the renal and liver functions. Serum sodium was 140 mEq/L, potassium 1.48 mEq/L, phosphorus 1.4 mEq/L. A random glucose was 155 mg/dl and the arterial Ph was 7.41. The urine potassium was 7.04 mEq/L, sodium 60.8 mg/dl. TSH levelwas < 0.03 ug/d], TUP 50.69% (24-40%), T4 17.6 ug/dl (4.7-11.4 ug/dl) Free T4 Index 28.23. He was managed with intravenous potassium chloride, 80 mEq in a period of seven hours with cardiac monitor. The serum potassium level, after the infusion was completed, was 6.70 mEq/L. No cardiac arrhythmia was

  16. One explanatory basis for the discrepancy of reported prevalences of sleep paralysis among healthy respondents.

    1993-12-01

    In a previous study, the author and coworkers found 39.8% of healthy young adults had experienced sleep paralysis. Some other studies reported prevalence as about the same or higher (i.e., 40.7% to 62.0%) than that previous estimate, while yet other studies, including Goode's work cited by ASDC and ASDA classifications, suggested much lower prevalences (i.e., 4.7% to 26.2%). The author tested the hypothesis that this discrepancy among the reported prevalences is partly due to the expression used in each questionnaire. University students who answered the questionnaire using the term 'transient paralysis' reported the lower prevalence (26.4%), while the second group of respondents who answered the questionnaire using the term kanashibari, the Japanese folklore expression for sleep paralysis, gave the higher prevalence (39.3%). The third group who answered the questionnaire with the term 'condition,' probably a rather neutral expression, marked the middle (31.0%) of these.

A retrospective study carried out between January 2008 and January 2012. Head and Neck Department, University Hospital of Modena, Modena, Italy. This was a retrospective analysis of 26 patients with unilateral vocal fold paralysis who underwent endoscopic injection of PDMS under general anesthesia. A voice evaluation protocol was performed for all patients, which included videolaryngostroboscopy, maximum phonation time, fundamental frequency, analysis of the harmonic structure of the vowel /a/ and the word /aiuole/, Grade of Dysphonia, Instability, Roughness, Breathiness, Asthenia, and Strain scale, and Voice Handicap Index. The protocol was performed before surgery, in the immediate postoperative period, and at least 3 years after surgery. The mean follow-up period was 73 months (range 39-119 months). The statistical analysis showed a significant improvement (P injection laryngoplasty with PDMS guarantees long-lasting effects over time. No complications were reported in our series. Injection laryngoplasty with PDMS can be considered to be a minimally invasive and safe technique for the treatment of unilateral vocal fold paralysis. Moreover, it allows very good and stable results to be obtained over time, avoiding repeated treatments and improving the quality of life of the patients. Copyright © 2017 The Voice Foundation.

    Full Text Available Bilateral vocal fold immobility may result from bilateral recurrent laryngeal nerve paralysis or physiologic insults to the airway such as glottic scars. The progression of mucosal injury to granulation tissue, and then posterior glottis stenosis, is an accepted theory but has not been photodocumented. This paper presents serial images from common postintubation injury to less common posterior glottic stenosis with interarytenoid synechia.

    Full Text Available We considered the estimation of energy in children's organism with cerebral paralysis. 16 children of secondary school age took part in research with spastic forms of a cerebral paralysis. It is established that children with a cerebral paralysis have the reduced energy parameters of the organism in comparison with children of the basic group of health. It is proved that specially organized outdoor games at the studies contribute to the growth of these indicators.

  20. Bell's palsy before Bell: Evert Jan Thomassen à Thuessink and idiopathic peripheral facial paralysis.

    Bell's palsy is the eponym for idiopathic peripheral facial paralysis. It is named after Sir Charles Bell (1774-1842), who, in the first half of the nineteenth century, discovered the function of the facial nerve and attracted the attention of the medical world to facial paralysis. Our knowledge of this condition before Bell's landmark publications is very limited and is based on just a few documents. In 1804 and 1805, Evert Jan Thomassen à Thuessink (1762-1832) published what appears to be the first known extensive study on idiopathic peripheral facial paralysis. His description of this condition was quite accurate. He located several other early descriptions and concluded from this literature that, previously, the condition had usually been confused with other afflictions (such as 'spasmus cynicus', central facial paralysis and trigeminal neuralgia). According to Thomassen à Thuessink, idiopathic peripheral facial paralysis and trigeminal neuralgia were related, being different expressions of the same condition. Thomassen à Thuessink believed that idiopathic peripheral facial paralysis was caused by 'rheumatism' or exposure to cold. Many aetiological theories have since been proposed. Despite this, the cold hypothesis persists even today.

    Introducing the lengthening temporalis myoplasty (LTM), a newly implemented surgical treatment of chronic facial paralysis. LTM is a single-stage operation where the temporalis muscle is transposed for dynamic smile reconstruction, hereby serving as an alternative to the more complex two-stage microvascular functional muscle transplantation. This case report demonstrates how LTM can be used to treat patients, who are not motivated or suitable for extensive surgery. The introduction of this technique aims to help a larger number of patients with chronic facial paralysis.

    Injury of the vertebral artery with cerebellar and brain stem infarction is a complication of cervical vertebral trauma. However, the pathogenesis and etiological factors remain to be clarified. In this study, we investigated patients with cervical vertebral and cord injury. This study included 51 patients with cervical vertebral and cord injury who were treated in our department. In these patients, plain X-ray, CT, MRI, and MRA findings were examined. The incidence of vertebral arterial injury was 33.3% (17 of 51 patients with cervical vertebral trauma). In 11 of the 17 patients, dislocation fracture was noted, comprising a markedly high percentage (64.7%). Particularly, vertebral arterial injury was commonly observed in patients with a large dislocation distance and severe paralysis. Cerebellar and brain stem infarction related to vertebral arterial injury was observed in 5 of the 17 patients (29.4%). No infarction developed in patients 50 years old or younger. Infarction was detected in relatively elderly patients. Vertebral arterial injury and cerebellar/brain stem infarction related to cervical vertebral trauma were frequently observed in patients with high energy injury. However, these disorders commonly occurred in elderly patients. Therefore, age-related factors such as arteriosclerosis may also be closely involved. In the acute stage, the state of the vertebral artery should be evaluated by MRA and MRI. Among patients with vertebral arterial injury, caution is needed during follow-up those with risk factors such as high energy injury and advanced age. (author)

  6. Closed-loop control of spinal cord stimulation to restore hand function after paralysis

    2014-05-01

    Full Text Available As yet, no cure exists for upper-limb paralysis resulting from the damage to motor pathways after spinal cord injury or stroke. Recently, neural activity from the motor cortex of paralyzed individuals has been used to control the movements of a robot arm but restoring function to patients’ actual limbs remains a considerable challenge. Previously we have shown that electrical stimulation of the cervical spinal cord in anesthetized monkeys can elicit functional upper-limb movements like reaching and grasping. Here we show that stimulation can be controlled using cortical activity in awake animals to bypass disruption of the corticospinal system, restoring their ability to perform a simple upper-limb task. Monkeys were trained to grasp and pull a spring-loaded handle. After temporary paralysis of the hand was induced by reversible inactivation of primary motor cortex using muscimol, grasp-related single-unit activity from the ventral premotor cortex was converted into stimulation patterns delivered in real-time to the cervical spinal grey matter. During periods of closed-loop stimulation, task-modulated electromyogram, movement amplitude and task success rate were improved relative to interleaved control periods without stimulation. In some sessions, single motor unit activity from weakly active muscles was also used successfully to control stimulation. These results are the first use of a neural prosthesis to improve the hand function of primates after motor cortex disruption, and demonstrate the potential for closed-loop cortical control of spinal cord stimulation to reanimate paralyzed limbs.

    Free muscle transfer for dynamic smile reanimation in facial paralysis is not always predictable with regard to cosmesis. Hospital stays range from 5 to 7 days. Prolonged operative times, longer hospital stays, and excessive cheek bulk are associated with free flap options. Lengthening temporalis myoplasty offers single-stage smile reanimation with theoretical advantages over free tissue transfer. From 2012 to 2014, 18 lengthening temporalis myoplasties were performed in 14 children for smile reconstruction. A retrospective chart review was completed for demographics, operative times, length of hospital stay, and perioperative complications. Fourteen consecutive patients with complete facial paralysis were included. Four patients underwent single-stage bilateral reconstruction, and 10 underwent unilateral procedures. Diagnoses included Möbius syndrome (n = 5), posterior cranial fossa tumors (n = 4), posttraumatic (n = 2), hemifacial microsomia (n = 1), and idiopathic (n = 2). Average patient age was 10.1 years. Average operative time was 410 minutes (499 minutes for bilateral lengthening temporalis myoplasty and 373 for unilateral lengthening temporalis myoplasty). Average length of stay was 3.3 days (4.75 days for bilateral lengthening temporalis myoplasty and 2.8 for unilateral lengthening temporalis myoplasty). Nine patients required minor revisions. Lengthening temporalis myoplasty is a safe alternative to free tissue transfer for dynamic smile reconstruction in children with facial paralysis. Limited donor-site morbidity, shorter operative times, and shorter hospital stays are some benefits over free flap options. However, revisions are required frequently secondary to tendon avulsions and adhesions. Therapeutic, IV.

    Unilateral vocal fold paralysis resulting in glottic incompetence can cause impairment of laryngeal functions, including airway protection and phonation. The objective of this study is to present an easy new technique for harvesting and injection of abdominal fat into the vocal fold for patients with unilateral vocal fold paralysis. This is a retrospective study of patients carried out on 16 patients suffering from unilateral vocal fold paralysis resulting from different etiologies. All patients were subjected to the protocol of voice assessment pre- and postoperatively. All patients were subjected to fat injection of the paralyzed vocal fold. There was a statistically significant difference between the pre- and postoperative grade of voice parameters. Vocal fold injection using fat medializes a paralyzed vocal fold by increasing vocal fold volume. Fat injections are safe and easily mastered; and in the absence of the standard settings for fat harvesting and injection, it could be performed with minimal equipment that are readily available in any operating room.

    2006-11-01

    Full Text Available We report the case of a 36-year-old woman who developed right upper and lower limb paralysis with sensory deficit after sedative drug overdose with prolonged immobilization. Due to the initial motor and sensory deficit pattern, brachial plexus injury or C8/T1 radiculopathy was suspected. Subsequent nerve conduction study/electromyography proved the lesion level to be brachial plexus. Painful swelling of the right buttock was suggestive of gluteal compartment syndrome. Elevation of serum creatine phosphokinase and urinary occult blood indicated rhabdomyolysis. The patient received medical treatment and rehabilitation; 2 years after the injury, her right upper and lower limb function had recovered nearly completely. As it is easy to develop complications such as muscle atrophy and joint contracture during the paralytic period of brachial plexopathy and lumbosacral plexopathy, early intervention with rehabilitation is necessary to ensure that the future limb function of the patient can be recovered. Our patient had suspected gluteal compartment syndrome that developed after prolonged compression, with the complication of concomitant lumbosacral plexus injury and brachial plexus injury, which is rarely reported in the literature. A satisfactory outcome was achieved with nonsurgical management.

    Full Text Available Abstract Thyrotoxic hypokalemic periodic paralysis (THPP is a rare, potentially life-threatening endocrine emergency. It is characterized by recurrent muscle weakness and hypokalemia. Because many THPP patients do not have obvious symptoms and signs of hyperthyroidism, misdiagnosis may occur. The published studies revealed that definitive therapy for THPP is control of hyperthyroidism by medical therapy, radioactive iodine or surgery, but the long-term post-operative follow-up result was not observed. We reported two cases of medically refractory THPP with recurrent paralysis of extremities and hypokalemia, and both were combined with thyroid nodules. Both patients were treated with total thyroidectomy; the pathology revealed that one is Graves' disease with thyroid papillary carcinoma, and the other is adenomatous goiter with papillary hyperplasia. No episode of periodic paralysis was noted and laboratory evaluation revealed normal potassium level during the post-operative follow up. Our experience suggests that total thyroidectomy by experienced surgeon is an appropriate and definite treatment for medically refractory THPP, especially in cases combined with thyroid nodules.

    Full Text Available Objective To explore the early diagnosis and the therapy of Sjogren's syndrome combined with hypokalemic periodic paralysis. Methods Clinical data of 2 cases with Sjogren's syndrome and hypokalemic periodic paralysis were analyzed. Results The first symptom of both two cases was suddenly or paroxysmal progressive four limbs weakness. The levels of serum potassium and chloride ion were decreased significantly, combined with alkaline urine, anti SS-A (+, anti SS-B (+, and sometimes with hyperthyroidism or hypothyroidism (the level of serum FT3 and FT4 being lower, or renal failure. In pathological examination of labial gland, mulifocality lymphocytes were seen in glandulae saliviae minores tissue in lower lip, or nature saliva flow rate measurement positive. All the patients' symptom improved after they were given potassium citrate, potassium chloride, sodium bicarbonate and levothyroxine (euthyrox. Conclusion The diagnosis of Sjogren's syndrome and hypokalemic periodic paralysis depends on comprehensive analysis of patient history, physical and laboratory examination. Early diagnosis and treatment can improve the prognosis. The treatment principle includes potassium supplement, correction of acidosis, improvement of thyroid function, and expectant alimentary support.

    Full Text Available Introduction Recurrent laryngeal nerve injury caused by cardiovascular disease is a rare condition, and often it is the only prominent sign of an imminent break of an aortic artery aneurysm. Objective To report left laryngeal paralysis caused by a great aortic arch aneurysm and to highlight the importance of an otorhinolaryngologic evaluation along with a thoracic radiologic study. Resumed Report A 42-year-old man complained of thickness of his voice and dysphagia for 3 months, but no thoracic pain or other relevant complaints. Video laryngoscopy revealed immobility of his left vocal fold in the paramedian position. Imaging was obtained for investigation, including magnetic resonance imaging of his thorax, which showed a fusiform aneurysm in the aortic arch, leading to recurrent compression of the left laryngeal nerve. The patient was successfully treated with endovascular repair of the aneurysm. At 2-month follow-up, there was still no recovery of the laryngeal mobility. Conclusion An aortic artery aneurysm can suddenly break, requiring emergency heart surgery, and the results can be fatal in many cases. We suggest routine exam of the vocal folds in all patients with a heart condition, and we review the literature and suggest the use of imaging to reduce the number of emergency procedures.

    We investigated whether experiencing right- or left-sided facial paralysis would affect an individual's ability to recognize one side of the human face using hybrid hemi-facial photos by preliminary study. Further investigation looked at the relationship between facial recognition ability, stress, and quality of life. To investigate predominance of one side of the human face for face recognition, 100 normal participants (right-handed: n = 97, left-handed: n = 3, right brain dominance: n = 56, left brain dominance: n = 44) answered a questionnaire that included hybrid hemi-facial photos developed to determine decide superiority of one side for human face recognition. To determine differences of stress level and quality of life between individuals experiencing right- and left-sided facial paralysis, 100 patients (right side:50, left side:50, not including traumatic facial nerve paralysis) answered a questionnaire about facial disability index test and quality of life (SF-36 Korean version). Regardless of handedness or hemispheric dominance, the proportion of predominance of the right side in human face recognition was larger than the left side (71% versus 12%, neutral: 17%). Facial distress index of the patients with right-sided facial paralysis was lower than that of left-sided patients (68.8 ± 9.42 versus 76.4 ± 8.28), and the SF-36 scores of right-sided patients were lower than left-sided patients (119.07 ± 15.24 versus 123.25 ± 16.48, total score: 166). Universal preference for the right side in human face recognition showed worse psychological mood and social interaction in patients with right-side facial paralysis than left-sided paralysis. This information is helpful to clinicians in that psychological and social factors should be considered when treating patients with facial-paralysis.

    Pneumonia is the leading cause of death after acute spinal cord injury and is associated with poor neurological outcome. In contrast to the current understanding, attributing enhanced infection susceptibility solely to the patient's environment and motor dysfunction, we investigate whether a secondary functional neurogenic immune deficiency (spinal cord injury-induced immune deficiency syndrome, SCI-IDS) may account for the enhanced infection susceptibility. We applied a clinically relevant model of experimental induced pneumonia to investigate whether the systemic SCI-IDS is functional sufficient to cause pneumonia dependent on spinal cord injury lesion level and investigated whether findings are mirrored in a large prospective cohort study after human spinal cord injury. In a mouse model of inducible pneumonia, high thoracic lesions that interrupt sympathetic innervation to major immune organs, but not low thoracic lesions, significantly increased bacterial load in lungs. The ability to clear the bacterial load from the lung remained preserved in sham animals. Propagated immune susceptibility depended on injury of central pre-ganglionic but not peripheral postganglionic sympathetic innervation to the spleen. Thoracic spinal cord injury level was confirmed as an independent increased risk factor of pneumonia in patients after motor complete spinal cord injury (odds ratio = 1.35, P spinal cord injury directly causes increased risk for bacterial infection in mice as well as in patients. Besides obvious motor and sensory paralysis, spinal cord injury also induces a functional SCI-IDS ('immune paralysis'), sufficient to propagate clinically relevant infection in an injury level dependent manner. © The Author (2016).

  18. Total Facial Nerve Decompression for Severe Traumatic Facial Nerve Paralysis: A Review of 10 Cases

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Management of traumatic facial nerve disorders is challenging. Facial nerve decompression is indicated if 90–95% loss of function is seen at the very early period on ENoG or if there is axonal degeneration on EMG lately with no sign of recovery. Middle cranial or translabyrinthine approach is selected depending on hearing. The aim of this study is to present retrospective review of 10 patients with sudden onset complete facial paralysis after trauma who underwent total facial nerve decompression. Operation time after injury is ranging between 16 and105 days. Excitation threshold, supramaximal stimulation, and amplitude on the paralytic side were worse than at least %85 of the healthy side. Six of 11 patients had HBG-II, one patient had HBG-I, 3 patients had HBG-III, and one patient had HBG-IV recovery. Stretch, compression injuries with disruption of the endoneurial tubules undetectable at the time of surgery and lack of timely decompression may be associated with suboptimal results in our series.

    To review current literature on types of distal triceps injury and determine diagnosis and appropriate management. We performed a systematic review in PubMed, Cochrane and EMBASE using the terms distal triceps tears and snapping triceps on the 10 th January 2017. We excluded all animal, review, foreign language and repeat papers. We reviewed all papers for relevance and of the papers left we were able to establish the types of distal triceps injury, how these injuries are diagnosed and investigated and the types of management of these injuries including surgical. The results are then presented in a review paper format. Three hundred and seventy-nine papers were identified of which 65 were relevant to distal triceps injuries. After exclusion we had 47 appropriate papers. The papers highlighted 2 main distal triceps injuries: Distal triceps tears and snapping triceps. Triceps tear are more common in males than females occurring in the 4 th -5 th decade of life and often due to a direct trauma but are also strongly associated with weightlifting and American football. The tears are diagnosed by history and clinically with a palpable gap. Diagnosis can be confirmed with the use of ultrasound (US) and magnetic resonance imaging. Treatment depends on type of tear. Partial tears can be treated conservatively with bracing and physio whereas acute tears need repair either open or arthroscopic using suture anchor or bone tunnel techniques with similar success. Chronic tears often need augmenting with tendon allograft or autograft. Snapping triceps are also seen more in men than women but at a mean age of 32 years. They are characterized by a snapping sensation mostly medially and can be associated with ulna nerve subluxation and ulna nerve symptoms. US is the diagnostic modality of choice due to its dynamic nature and to differentiate between snapping triceps tendon or ulna nerve. Treatment is conservative initially with activity avoidance and if that fails surgical

    Any process involving either the vagus nerve, its recurrent laryngeal branch or the external branch of the superior laryngeal nerve may cause paralysis of the vocal fold. The most common cause is neoplasm. Clinically, the patients often present with a hoarse, breathy voice as well as symptoms of aspiration. The following represents a unique case of unilateral vocal fold paralysis and dysphagia caused by a degenerative disease of the cervical spine, resluting in extrinsic compression of the recurrent laryngeal nerve.

    To observe the clinical effect difference between special penetration needling and conventional penetration needling for the refractory peripheral facial paralysis. A total of 97 patients with intractable facial paralysis were randomized into an observation group (49 cases and 2 dropping) and a control group (48 cases and 4 dropping). In the observation group, special penetration needling at an angle about 45° between the penetration needle and paralysis muscle bundle was used, Yangbai (GB 14) through Touwei (ST 8), Yangbai (GB 14) through Shangxing (GV 23), Sizhukong (TE 23) through Yuyao (EX-HN 4), Qianzhen (Extra) through Yingxiang (LI 20), mutual penetration between Yingxiang (LI 20) and Jiache (ST 6). Conventional penetration needling was applied in the control group, Yangbai (GB 14) through Yuyao (EX-HN 4), Cuanzhu (BL 2) through Yuyao (EX-HN 4), mutual penetration between Dicang (ST 4) and Jiache (ST 6), Qianzheng (Extra) through Dicang (ST 4), Sibai (ST 2) through Yingxiang (LI 20). Three groups of electroacupuncture (discontinuous wave, 1 Hz) with tolerance were connected respectively in the two groups, Yangbai (GB 14) and Sizhukong (TE 23), Yangbai (GB 14) and Qianzheng (Extra), Yingxiang (LI 20) and Jiache (ST 6) in the observation group, Yangbai (GB 14) and Cuanzhu (BL 2), Dicang (ST 4) and Jiache (ST 6), Qianzheng (Extra) and Sibai (ST 2) in the control group. TDP was applied in the two groups at the affected Yifeng (TE 17), Jiache (ST 6) and Qianzheng (Extra), which were around the ear. Perpendicular insertion was used at Yifeng (TE 17) at the affected side and Hegu (LI 4) at the healthy side and bilateral Zusanli (ST 36). The needles were retained for 30 min. The treatment was given for 3 courses, once a day and 10 days as a course, 5 days at the interval. House-Brackmann (H-B) facial nerve grading score was recorded before and after treatment. The clinical effects were compared. The H-B scores after treatment in the two groups were higher than

    The most common disorder of the facial nerve is acute idiopathic facial paralysis or Bell's palsy and there may be significant morbidity or incomplete recovery associated with severe cases. To assess the efficacy of aciclovir or similar agents for treating Bell's palsy. We searched the Cochrane Neuromuscular Disease Group register (searched April 2003), MEDLINE (from January 1966 to April 2003), EMBASE (from January 1980 to April 2003) and LILACS (from January 1982 to April 2003). We also contacted authors of identified trials. Randomised or quasi-randomised trials of aciclovir or valaciclovir therapy, alone or in combination with any other drug, in patients with Bell's palsy. We identified six randomised trials. Three studies met our inclusion criteria, including 246 patients. One study evaluated aciclovir with corticosteroid versus corticosteroid alone, another study evaluated aciclovir alone versus corticosteroid and a further study evaluated valaciclovir with corticosteroid versus corticosteroid alone or versus placebo alone. Incomplete recovery after one year: data were not available. An analysis was performed on data reported at the end of the study period in each trial. The results from one study four months after the start of treatment significantly favoured the treatment group, whilst the results of the study three months after the start of treatment significantly favoured the control group. The results from the second study at four months showed no statistically significant difference between the three groups.Adverse events: relevant data were not reported in any of the three trials.Complete facial paralysis six months after start of treatment: only one patient had complete paralysis upon entering one of the studies. This patient was assigned to the control group and the level of recovery attained was not reported.Motor synkinesis or crocodile tears one year after start of treatment: data were available up to a maximum of four months after onset of

    Background Facial nerve paralysis in a patient with a salivary gland mass usually denotes malignancy. However, facial paralysis can also be caused by benign salivary gland tumors. Methods We present a case of facial nerve paralysis due to a benign salivary gland tumor that had the imaging characteristics of an intraparotid facial nerve schwannoma. Results The patient presented to our clinic 4 years after the onset of facial nerve paralysis initially diagnosed as Bell palsy. Computed tomography demonstrated filling and erosion of the stylomastoid foramen with a mass on the facial nerve. Postoperative histopathology showed the presence of a pleomorphic adenoma. Facial paralysis was thought to be caused by extrinsic nerve compression. Conclusions This case illustrates the difficulty of accurate preoperative diagnosis of a parotid gland mass and reinforces the concept that facial nerve paralysis in the context of salivary gland tumors may not always indicate malignancy.

  6. Lower-Extremity Weakness in a Teenager Due to Thyrotoxic Periodic Paralysis.

    Science.gov (United States)

    Thornton, Matthew D

    2017-04-01

    Thyrotoxic hypokalemic paralysis is the hallmark of thyrotoxic periodic paralysis (TPP). TPP is a potentially deadly complication of hyperthyroidism that occurs because of rapid and dramatic intracellular shift of potassium. This transference results in severe hypokalemia and clinically manifests itself as muscle weakness or paralysis. This condition predominantly affects males of Asian descent, and its presentation can range from mild to severe, as seen in our case. We present the case of a 15-year-old Asian-American male who presented to a tertiary-care pediatric emergency department complaining of generalized weakness and flaccid paralysis of his lower extremities. The differential for such a complaint is extremely broad, and the symptoms can result from etiologies arising from the cerebral cortex, the spinal cord, peripheral nerves, the neuromuscular junction, or even the muscles themselves. Our patient was found to have an extremely low serum potassium concentration, as well as an electrocardiogram that revealed a prolonged QT interval and right bundle branch block. The etiology of these abnormalities and the patient's symptoms was found to be undiagnosed and uncontrolled hyperthyroidism from Grave's disease, which resulted in this dramatic presentation of thyrotoxic hypokalemic paralysis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This entity is common in Asia but still somewhat rare in the United States and other Western countries. Our case illustrates that careful history taking and a focused diagnostic evaluation, in conjunction with having an awareness of this disease, can help expedite diagnosis and management, as well as avoid unnecessary and potential harmful testing in the emergency department setting.

    Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. All ethnicities can be affected, but TPP typically presents in men of Asian descent. The most common cause of TPP in thyrotoxicosis is Graves' disease. However, TPP can occur with any form of thyrotoxicosis. Up to our knowledge, very few cases ever reported the relationship between TPP and painless thyroiditis. We herein report a 25-yr-old Korean man who suffered from flaccid paralysis of the lower extremities and numbness of hands. The patient was subsequently diagnosed as having TPP associated with transient thyrotoxicosis due to painless thyroiditis. The paralytic attack did not recur after improving the thyroid function. Therefore, it is necessary that early diagnosis of TPP due to transient thyrotoxicosis is made to administer definite treatment and prevent recurrent paralysis.

    2010-01-01

    This study reports 4 cases of occult parotid malignancy presenting with sudden-onset facial paralysis to demonstrate that failure to regain tone 6 months after onset distinguishes these patients from Bell's palsy patients with delayed recovery and to propose a diagnostic algorithm for this subset of patients. A case series of 4 patients with occult parotid malignancies presenting with acute-onset unilateral facial paralysis is reported. Initial imaging on all 4 patients did not demonstrate a parotid mass. Diagnostic delays ranged from 7 to 36 months from time of onset of facial paralysis to time of diagnosis of parotid malignancy. Additional physical examination findings, especially failure to regain tone, as well as properly protocolled radiologic studies reviewed with dedicated head and neck radiologists, were helpful in arriving at the diagnosis. An algorithm to minimize diagnostic delays in this subset of acute facial paralysis patients is presented. Careful attention to facial tone, in addition to movement, is important in the diagnostic evaluation of acute-onset facial paralysis. Copyright 2010 Elsevier Inc. All rights reserved.

  10. Respiratory Management in the Patient with Spinal Cord Injury

    Directory of Open Access Journals (Sweden)

    Rita Galeiras Vázquez

    2013-01-01

    Full Text Available Spinal cord injuries (SCIs often lead to impairment of the respiratory system and, consequently, restrictive respiratory changes. Paresis or paralysis of the respiratory muscles can lead to respiratory insufficiency, which is dependent on the level and completeness of the injury. Respiratory complications include hypoventilation, a reduction in surfactant production, mucus plugging, atelectasis, and pneumonia. Vital capacity (VC is an indicator of overall pulmonary function; patients with severely impaired VC may require assisted ventilation. It is best to proceed with intubation under controlled circumstances rather than waiting until the condition becomes an emergency. Mechanical ventilation can adversely affect the structure and function of the diaphragm. Early tracheostomy following short orotracheal intubation is probably beneficial in selected patients. Weaning should start as soon as possible, and the best modality is progressive ventilator-free breathing (PVFB. Appropriate candidates can sometimes be freed from mechanical ventilation by electrical stimulation. Respiratory muscle training regimens may improve patients’ inspiratory function following a SCI.

    2016-01-01

    Full Text Available Phantom Limb Pain is a disorder that can be experienced by individuals after amputation or spinal cord injury. In spinal cord injury the paralysis or paresis is often bilateral, thus limiting the application of apparent movement as a therapeutic model for phantom limb pain. This project aimed to develop a robotic rehabilitation device that replicated apparent movement to apply the same therapeutic principles with individuals with lower limb phantom pain that have bilateral paralysis of paresis. The proposed device achieved lower limb planar motion of the knee by a six-bar linkage of a single degree of freedom (DOF. It is driven by a linear actuator while the ankle motion is achieved by a gear motor, reaching an effective 70° range of motion for both joints. The system features closed loop control using feedback from surface electromyography sensors, limit switches and position sensors with an Arduino microcontroller as the control unit. This device will be used to further our understanding of the disorder and create opportunities for robot aided treatment for individuals with phantom limb pain as a result of spinal cord injury.

    Full Text Available Abstract Background Enteroviruses are among the most common viruses infecting humans worldwide and they are associated with diverse clinical syndromes. Acute flaccid paralysis (AFP is a clinical manifestation of enteroviral neuropathy, transverse myelitis, Guillian-Barre Syndrome, Traumatic neuritis and many other nervous system disorders. The objective of this study was to understand the role of Non-Polio Enteroviruses (NPEV towards this crippling disorder. Methods Stool specimens of 1775 children, aged less than 15 years, suffering from acute flaccid paralysis were collected after informed consent within 14 days of onset of symptoms during January 2003 to September 2003. The specimens were inoculated on RD and L20B cells using conventional tube cell culture while micro-neutralization test was used to identify the non-polio enterovirus (NPEV serotypes. Detailed clinical information and 60-days follow-up reports were analyzed for NPEV-associated AFP cases. Results NPEV were isolated from 474 samples. The male to female ratio was 1.4:1. The isolation of NPEV decreased significantly with the increase in age. Cases associated with fever at the onset of NPEV-associated AFP were found to be 62%. The paralysis was found asymmetrical in 67% cases, the progression of paralysis to peak within 4 days was found in 72% cases and residual paralysis after 60 days of paralysis onset was observed in 39% cases associated with NPEV. A clinical diagnosis of Guillian-Barre syndrome was made in 32% cases. On Microneutralization assay, echo-6 (13% and coxsackievirus B (13% were the most commonly isolated serotypes of NPEV along with E-7, E-13, E-11, E-4 and E-30. The isolates (n = 181 found untypable by the antiserum pools were confirmed as NPEV by PCR using Pan-Enterovirus primers. Conclusion The present study suggests that NPEV are a dominant cause of AFP and different serotypes of NPEV are randomly distributed in Pakistan. The untypable isolates need further

    Full Text Available Objectives. To describe 2 cases of thyrotoxic periodic paralysis. Methods. We report of 2 cases of thyrotoxic periodic paralysis in 2 individuals from 2 different backgrounds with emphasis on their presentation and treatment. We also conducted a literature search to put together an update review of thyrotoxic periodic paralysis. Results. A 47-year-old Chinese and 28-year-old Caucasian male presented with profound yet reversible weakness associated with hypokalemia on admission bloods and thyrotoxicosis. Both were given definitive therapy to prevent recurrence of attacks with any future relapse of thyrotoxicosis. Conclusion. Thyrotoxic periodic paralysis (TPP is a rare but potentially serious complication of thyrotoxicosis resulting in temporary but severe muscle weakness. Recent discovery of a novel mutation in the KCNJ18 gene which codes for an inwardly rectifying potassium channel and is controlled by thyroid hormones may provide greater insight into the pathogenesis of TPP.

    2015-09-01

    Thyrotoxic periodic paralysis (TPP) is characterized by the presence of muscle paralysis, hypokalemia, and hyperthyroidism. We report the case of a young man with paralysis of the lower extremities, severe hypokalemia, and concurrent hyperthyroidism. TPP was suspected; therefore, treatment consisting of judicious potassium (K+) repletion and β-blocker administration was initiated. However, urinary K+ excretion rate, as well as refractoriness to treatment, was inconsistent with TPP. Chronic alcoholism was considered as an alternative cause of hypokalemia, and serum K+ was restored through vigorous K repletion and the addition of K+ -sparing diuretics. The presence of thyrotoxicosis and hypokalemia does not always indicate a diagnosis of TPP. Exclusion of TPP can be accomplished by immediate evaluation of urinary K+ excretion, acid-base status, and the amount of potassium chloride required to correct hypokalemia at presentation.

    Full Text Available Background. Parsonage-Turner syndrome, or neuralgic amyotrophy (NA, is an acute brachial plexus neuritis that typically presents with unilateral shoulder pain and amyotrophy but also can affect other peripheral nerves, including the recurrent laryngeal nerve. Idiopathic vocal fold paralysis (VFP represents approximately 12% of the VFP cases and recurrence is extremely rare. Methods and Results. We report a man with isolated recurrent unilateral right VFP and a diagnosis of NA years before. Conclusions. We emphasize that shoulder pain and amyotrophy should be inquired in any patient suffering from inexplicable dysphonia, and Parsonage-Turner syndrome should be considered in the differential diagnosis of idiopathic VFP.

    2017-08-01

    Full Text Available An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted laryngeal architecture suggestive of extraluminal compression. Histopathology results of incisional biopsies from the mass were suggestive of a benign non-neoplastic muscular lesion. Surgery was performed to manage laryngeal paralysis and attempt mass excision. A second histopathology examination confirmed an inflammatory and dysplastic lesion suggestive of a pseudotumour. All clinical signs resolved after surgery and at the 13 months follow-up the dog remains asymptomatic. To the authors’ knowledge, this is the first report of a case of laryngeal paralysis caused by a muscle pseudotumour in a young dog.

    Full Text Available Background : The western literature on deep vein thrombosis (DVT and pulmonary embolism (PE following spinal cord injury (SCI report an alarmingly high incidence, necessitating thromboprophylaxis. The literature on incidence from the Asian subcontinent is scanty and from India is almost nonexistent. Materials and Methods : Seventy hospitalized acute SCI patients presenting within five days of the injury were included in the present analysis. Forty-two cases were subjected to color Doppler studies and 28 cases had to be subjected to venography due to lack of facility at some point of time. The clinical course of the patients was closely observed during the period of hospitalization. All except 14 were managed nonoperatively. Thromboprophylaxis was not given to any patient at any stage; however, treatment was instituted in those showing the features of DVT on investigations. Results : Twelve patients died during the period of hospitalization. Deep vein thrombosis could be detected in seven patients only, three in the proximal and four in the distal segment of the lower limb and of these three died. Based on the clinical course and positive investigation report in favor of DVT, we presumed that the cause of death in these three patients was pulmonary embolism. In the other nine, in the absence of an autopsy report, the cause of deaths was considered as pulmonary infection, asphyxia, diaphragmatic paralysis, hematemesis, cervicomedullary paralysis etc. Clinical features to diagnose DVT were of little help. Conclusions : There is a much lower incidence (10% of DVT and PE following spinal cord injury (SCI in India than what is reported from the western countries. Higher age group and quadriplegia were the only factors which could be correlated. Deep vein thrombosis extending proximal to the knee was significant. In the absence of autopsy and other screening tests like D-dimer test or 125I fibrogen uptake study, the true incidence of venous

    Long-standing peripheral monolateral facial paralysis in the adult has challenged otolaryngologists, neurologists and plastic surgeons for centuries. Notwithstanding, the ultimate goal of normality of the paralyzed hemi-face with symmetry at rest, and the achievement of a spontaneous symmetrical smile with corneal protection, has not been fully reached. At the beginning of the 20(th) century, the main options were neural reconstructions including accessory to facial nerve transfer and hypoglossal to facial nerve crossover. In the first half of the 20(th) century, various techniques for static correction with autologous temporalis muscle and fascia grafts were proposed as the techniques of Gillies (1934) and McLaughlin (1949). Cross-facial nerve grafts have been performed since the beginning of the 1970s often with the attempt to transplant free-muscle to restore active movements. However, these transplants were non-vascularized, and further evaluations revealed central fibrosis and minimal return of function. A major step was taken in the second half of the 1970s, with the introduction of microneurovascular muscle transfer in facial reanimation, which, often combined in two steps with a cross-facial nerve graft, has become the most popular option for the comprehensive treatment of long-standing facial paralysis. In the second half of the 1990s in France, a regional muscle transfer technique with the definite advantages of being one-step, technically easier and relatively fast, namely lengthening temporalis myoplasty, acquired popularity and consensus among surgeons treating facial paralysis. A total of 111 patients with facial paralysis were treated in Caen between 1997 and 2005 by a single surgeon who developed 2 variants of the technique (V1, V2), each with its advantages and disadvantages, but both based on the same anatomo-functional background and aim, which is transfer of the temporalis muscle tendon on the coronoid process to the lips.

    Our study examines a recreational curling population to describe patterns of injury occurrence, estimate risk of injury and to gauge attitudes towards equipment-based prevention strategies. In a retrospective case series, we queried the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), a national injury surveillance database, for curling injuries entered between 1993 and 2011. Kingston General Hospital and Hotel Dieu Hospital provide the two Kingston, Ontario, sites for emergency department (ED) care and participate in CHIRPP. Each retrieved entry underwent a chart review. A secondary survey was mailed to select individuals who had experienced curling injuries to solicit details on their injury and attitudes towards equipment to prevent injury. We used descriptive statistics for rates and proportions. Over 90% of acute curling injuries resulted from a fall, and 31.7% were head impacts. We found that acute injuries requiring ED presentation occur at a rate of approximately 0.17 per 1000 athlete-exposures (95% CI: 0.12-0.22). The secondary survey was completed by 54% of potential respondents. Of survey respondents, 41.3% attributed their fall to a lack of proper footwear and 73.5% of respondents agreed with mandatory sport-specific footwear as a prevention strategy, but only 8% agreed with mandatory helmet wear. Although curling injuries requiring medical care are not common, head injuries make up a large proportion. Mandated use of appropriate footwear appears to be the most effective prevention strategy, as well as the measure deemed most acceptable by players.

    We present a case in which Gilbert syndrome was diagnosed following a neuro-ophthalmic complaint. Adverse effects of drugs as well as various systemic, neurological, and local ocular pathologies can cause accommodative insufficiency and loss of accommodation. A 29-year-old man was admitted to an ophthalmology department with blurred vision and diagnosed as suffering from acute accommodation paralysis. He had a history of being given a pheniramine maleate injection for pruritus 20 days previously. Symptoms began immediately following the injection. After systemic evaluation and laboratory tests, he was diagnosed as having Gilbert syndrome. His complaints and symptoms recovered in approximately a further 10 days. Metabolism of pheniramine maleate can be impaired in Gilbert syndrome and anticholinergic effects can cause accommodation paralysis.

    Objective: To investigate the characteristics of spinal MR images in acute flaccid paralysis (AFP) associated with enterovirus 71 infected hand-foot-mouth disease. Methods: The spinal MR images of eight infants with AFP and positive EV71 cultures were analyzed during an outbreak of hand-foot-mouth disease in China in 2008. Results: Acute paralysis was observed in one lower limb in 4 of the 8 patients, in four limbs in 2 patients, in one upper limb and both lower limbs in 1 patient, 2 of the 8 patients also had brain stem encephalitis. Lesions were identified in anterior horn regions of spinal cord with hyperintensity on T 2 -weighted images and hypointensity on T 1 -weighted images. Location of the lesions included C3 to C7 (1 case), T10 extending to conus medullaris (5 cases) and a combination of the above (2 cases). Five of the 8 patients presented with unilateral paralysis. Two of the 5 cases showed unilateral hyperintense lesions in anterior horn regions and the remaining 3 cases showed bilateral hyperintense lesions in anterior horn regions with a unilateral predominance. One of the 3 patients with bilateral lesions showed slight enhancement of anterior horn with prominent enhancement of ventral roots after intravenous injections of contrast medium. Three of the 8 patients with bilateral paralysis showed bilateral hyperintensity in both anterior horn regions. Conclusion: MR is the imaging modality of choice for the detection of radiculomyelitis of AFP associated with EV71 infection. (authors)

  9. Malaria fever therapy for general paralysis of the insane in Denmark.

    2010-12-01

    This article explores the history of general paralysis and malaria fever therapy in Denmark. I argue that the small size of the country gave Danish psychiatrists excellent opportunities for performing statistical studies of general paralysis in the 19th century. In the early 1920s malaria fever therapy was introduced in Danish mental hospitals and raised hopes of a cure for paralytics. Malaria fever therapy became popular among Danish psychiatrists, but the new therapy also raised ethical questions and led to the first regulations concerning informed consent in the history of Danish psychiatry.

    To assess the outcomes of management of unilateral vocal fold paralysis by ansa-RLN reinnervation in a series of patients ages 12-21. Clinical outcomes study. Six consecutive adolescents and young adults (ages 12-21 years) seeking treatment for unilateral vocal fold paralysis and glottal incompetence underwent ansa-RLN neurorraphy. Pre- and post-operative voice recordings acquired at least 1 year following surgery were submitted to acoustic and perceptual analysis. Patient-based measures were also taken. Mean perceptual visual analogue scale rating of dysphonia severity (0mm=profoundly abnormal voice, 100mm=completely normal voice) improved from 50mm pre-operatively to 82mm post-operatively. Mean maximum phonation time improved from 6.5s to 13.2s. Pitch and dynamic range were also observed to improve. Global self-ratings of voice function (0-100%) increased from 31.2% to 81.6% of normal. Ansa-RLN reinnervation is an effective treatment option for adolescents and young adults with unilateral vocal fold paralysis. The procedure has the potential to improve vocal function substantially, especially in those with isolated paralysis of the recurrent laryngeal nerve. The procedure alleviates the disadvantages associated with other surgical options for this age group.

    Objective: Recognition of common causes of acute flaccid paralysis in children. Study Design: Descriptive study. Place and Duration of Study: Combined Military Hospital Peshawar, from Aug 2009 to Jun 2012. Material and Methods: The demographic data including age, gender and clinical data including history of injection, stool results, and final diagnosis (polio, non-polio enterovirus, traumatic injection neuritis, GBS and an unknown group) were expressed in terms of frequencies and percentages. Chi-square test was applied for the association of age-groups with various causes of AFP. A p-value of less than 0.05 was taken as statistically significant. SPSS version 20 was used for statistical analyses. Results: Injection neuritis and post-viral paralysis (polio, non-polio enterovirus) were the common causes of AFP. Conclusion: As the study identified common causes of AFP which are essentially preventable, it highlighted certain issues during the process. First is the lack of nursing staff training or iatrogenic disability due to quackery, which requires urgent intervention to prevent it. Second is a deficiency in the WHO management protocol for AFP. NCS EMG proved to be a vital diagnostic tool for AFP, which is not included in the WHO AFP protocol at present.It is suggested that this diagnostic modality should be included in the AFP diagnostic protocol for better diagnostic yield.

    Damage to the facial nerve due to trauma from traffic accidents is the second most common cause of paralysis of the facial nerve. The treatments include both pharmacological and non-pharmacological therapy. Acupuncture is a method of treatment that applies evidence-based medical principles and uses anatomy, physiology, and pathology to place needles atcertain acupuncture points. This paper describes a 26-year-old female patient with right-side facial palsy following a traffic accident who had animproved Brackmann’s score after 12 sessions of acupuncture treatment. The acupuncture points were chosen based on Liu Yan’sbrain-clearing needling technique. Acupuncture can shorten healing time and improve the effect of treatment for facial-nerve paralysis.

    Patients with unilateral vocal fold paralysis may demonstrate different degrees of voice perturbation depending on the position of the paralyzed vocal fold. Understanding the effectiveness of voice therapy in this population may be an important coefficient to define the therapeutic approach. To evaluate the voice therapy effectiveness in the short, medium and long-term in patients with unilateral vocal fold paralysis and determine the risk factors for voice rehabilitation failure. Prospective study with 61 patients affected by unilateral vocal fold paralysis enrolled. Each subject had voice therapy with an experienced speech pathologist twice a week. A multidimensional assessment protocol was used pre-treatment and in three different times after voice treatment initiation: short-term (1-3 months), medium-term (4-6 months) and long-term (12 months); it included videoendoscopy, maximum phonation time, GRBASI scale, acoustic voice analysis and the portuguese version of the voice handicap index. Multiple comparisons for GRBASI scale and VHI revealed statistically significant differences, except between medium and long term (pvocal improvement over time with stabilization results after 6 months (medium term). From the 28 patients with permanent unilateral vocal fold paralysis, 18 (69.2%) reached complete glottal closure following vocal therapy (p=0.001). The logistic regression method indicated that the Jitter entered the final model as a risk factor for partial improvement. For every unit of increased jitter, there was an increase of 0.1% (1.001) of the chance for partial improvement, which means an increase on no full improvement chance during rehabilitation. Vocal rehabilitation improves perceptual and acoustic voice parameters and voice handicap index, besides favor glottal closure in patients with unilateral vocal fold paralysis. The results were also permanent during the period of 1 year. The Jitter value, when elevated, is a risk factor for the voice therapy

    Full Text Available Background: Brachial plexus is a network of nerves that controls the upper limb. Unfortunately, it can be injured easily which is called brachial plexus injury (BPI. It can cause disability. Until now, the epidemiology of BPI in Indonesia is still lacking. The aim of this study was to describe the characteristics of patients with BPI in Bandung, in order to increase knowledge and attention of health care provider and community to prevent BPI. Methods: This was a descriptive retrospective study. Data from medical records of patients with BPI who underwent electromyography (EMG in Neurophysiology Laboratory Dr. Hasan Sadikin General Hospital, Bandung from 2003 to 2012 were collected. The data included age, sex, mode of injury, affected side and distribution of paralysis. Collected data were presented as percentages shown in tables. Results: A total of 91 cases were collected during study period, which consisted of 69 males and 22 females (76% vs. 24%. Most of them were in productive age group (11−20 years and 21−30 years. The main cause of brachial plexus injury was traffic accident (76%, followed by birth injury. Distribution of paralysis was mostly in postganglionic area of cervical (C5, C6, C7, C8 and thoracal (T1 (67%. Around two third of the cases involved the right side of upper limb. Conclusions: The study showed that most of patients with BPI are male in their productive ages. Traffic accident is the most common cause, and the most affected side is the right side of upper limb.

    To evaluate the clinical outcome of patients with acute vocal fold paralysis treated with bovine collagen via percutaneous injection laryngoplasty under simple topical anesthesia. Retrospective case series. The charts of 38 consecutive patients with acute unilateral vocal fold paralysis who underwent percutaneous injection laryngoplasty under simple topical anesthesia were reviewed. Symptoms and laryngeal function were assessed pre- and postinjection using the Glottal Function Index (GFI), GRBAS Dysphonia Scale, Functional Outcome Swallowing Scale (FOSS), and maximum phonation time (MPT). Mean GFI, GRBAS, FOSS, and MPT improved from 13.71 to 7.68, 7.24 to 3.95, 3.70 to 2.20, and 12.87 to 16.45, respectively (P dysphagia and aspiration, injection was successful in restoring oral alimentation in only three patients, with the four failures occurring in patients with multiple cranial neuropathies. Percutaneous injection laryngoplasty is a viable option for immediate rehabilitation of acute vocal fold paralysis, and can be performed in the inpatient setting. With dysphagia and aspiration secondary to multiple cranial nerve palsies, medialization of the paralyzed cord alone may be insufficient to restore safe oral alimentation.

    Before the introduction of computerized tomography (CT) there were some cases of intracerebral bleeding who were wrongly diagnosed as hypertensive encephalopathy or senile psychosis. We here report 5 cases who did not show any sign of motor paralysis. The clinical aspects of these cases were nausea and vomiting with dizziness (case 1), nausea and vomiting with slight headache (case 2), agnosia of left side with several kinds of disorientation (case 3), nausea and vomiting (case 4), and visual disturbance of right, lower quadrant (case 5). All of these cases showed no motor paralysis or abnormal reflex activities. By examination with CT each of them exhibited a high density area in the subcortical area of the right parietal lobe, the subcortical area of the right occipital lobe, the right temporal and parietal lobe, rather small portion of the left putamen and external capsule, and the subcortical area of left occipital lobe, respectively. Patients of cerebral hemorrhage without motor or sensory disturbances might often be taken for some psychic abnormality. We here have emphasized the importance of CT in such a group of patients. But for this technique, most of them would not be given adequate treatment and might be exposed to lifethreatening situations. (author)

    2017-01-01

    Diffuse idiopathic skeletal hyperostosis (DISH) is an idiopathic spinal disease common in the elderly and characterized by flowing ossification and osteophyte formation along the spinal column. Cervical hyperostosis is capable of producing dysphagia, stridor, and airway obstruction; however, there are no extant reports of true paralysis of bilateral vocal folds in patients fulfilling the criteria for DISH. We report a case of a 61-year-old man presenting with dysphagia and dyspnea. Flexible laryngoscopy revealed bilateral true vocal fold paralysis. Cervical radiograph showed flowing ossification of the anterior longitudinal ligament with preservation of intervertebral disc height. Tracheotomy and cervical osteophytectomy were performed, after which the patient showed improved swallowing and speaking ability and was decannulated without complication. In the case presented, cervical osteophytectomy dramatically reversed bilateral vocal fold paralysis and dysphagia secondary to hyperostosis, thus negating the need for prolonged tracheostomy and feeding tube dependence. © 2016 Wiley Periodicals, Inc.

    Vocal fold paralysis (VFP) is an increasingly commonly identified problem in the pediatric patient. Diagnostic and management techniques honed in adult laryngologic practice have been successfully applied to children. Iatrogenic causes, including cardiothoracic procedures, remain a common cause of unilateral VFP. Neurologic disorders predominate in the cause of bilateral VFP. Diagnosis with electromyography is currently being evaluated in children. Treatment of VFP is centered around symptomology, which is commonly divided between voice and airway concerns. Speech therapy shows promise in older children. Surgical management for unilateral VFP with injection laryngoplasty is commonly performed and well tolerated. Laryngeal reinnervation is currently being applied to the pediatric population as a permanent treatment and offers several advantages over laryngeal framework procedures. For bilateral VFP, tracheotomy is still commonly performed. Glottic dilation procedures are performed both openly and endoscopically with a high degree of success. VFP is a well recognized problem in pediatric patients with disordered voice and breathing. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment.

    Preliminary evidence suggests that peripheral facial nerve injuries are associated with sensorimotor cortex reorganization. We have characterized facial nerve lesion-induced structural changes in primary motor cortex layer 5 pyramidal neurons and their relationship with glial cell density using a rodent facial paralysis model. First, we used adult transgenic mice expressing green fluorescent protein in microglia and yellow fluorescent protein in pyramidal neurons which were subjected to eithe...

    Hypokalemic Periodic Paralyses comprise diverse diseases characterized by acute and reversible attacks of severe muscle weakness, associated with low serum potassium. the most common causes are Familial Hypokalemic Periodic Paralysis (FHypoKPP), an autosomal dominant disease, and Thyrotoxic Hypokalemic Periodic Paralysis (THypoKPP), secondary to thyrotoxicosis. Symptoms of paralysis are similar in both diseases, distinguished by thyrotoxicosis present in THypoKPP. FHypoKPP is caused by mutati...

    Full Text Available Background Bilateral abductor vocal fold paralysis can lead to respiratory distress and dyspnea. Objectives To assess the efficacy of CO 2 laser unilateral posterior cordotomy in cases with bilateral abductor paralysis as regards improvement of dyspnea with preservation of satisfactory voice and swallowing after the operation. Methods A prospective study was done on 18 patients with bilateral abductor vocal fold paralysis (10 females and 8 males from November 2010 to December 2012 with their ages ranging from 32 to 64 years. Results All patients showed improvement of dyspnea after the operation, most of the patients suffered from mild to moderate dyspnea in the immediate post-operative period, and two patients needed another intervention to solve it. All the patients had satisfactory results of their voice after the operation, and one patient only suffered from temporary aspiration. Conclusion Unilateral CO 2 laser posterior cordotomy is an easy and effective procedure to solve the dyspnea after bilateral vocal fold abductor paralysis without aspiration or significant voice alteration.

    Nervus abducens is a pure motor nerve located in the pons. It retracts the eyeball laterally by stimulating rectus lateralis muscle. In case of their paralysis, diplopia and restriction in the eye movements while looking sideways, are seen. Since the same signs are seen due to the muscle entrapment in blowout fractures, its differential diagnosis has importance in terms of the treatment protocol and avoiding unnecessary operations. In this article, we present a 22-year-old male patient who was referred to our department due to the prediagnosis of blowout fracture following maxillofacial trauma. However, he was diagnosed with abducens nerve paralysis after the consultations and analysis and his restriction of movement was resolved via systemic steroid treatment instead of unnecessary operation.

    Eighty-seven patients aged 16-68 years have been examined by magnetic resonance imaging (MRI) following spinal injury. The MRI findings have been correlated with length of history between trauma and investigation, extent of residual function and site of injury. They include changes at the site of injury consistent with myelomalacia in 37%, a syrinx in 40%, persistent cord compression in 32% and atrophy in 18%. An extensive syrinx can develop within 2 months of injury and it is nearly twice as common in patients with complete paralysis as in those whose paralysis was incomplete. It is suggested that investigation and management of spinal trauma should include early and repeated MRI examinations to detect sequelae at an early stage. (orig.)

    Unilateral vocal fold paralysis (UVFP) is a complication associated with cardiothoracic procedures that presents clinically as dysphonia and/or dysphagia with or without aspiration. The literature lacks both data on recovery of mobility and consensus on best management. Herein, our goals are to 1) Identify cardiothoracic procedures associated with symptomatic UVFP at our institution; 2) Review timing and nature of laryngology diagnosis and management; 3) Report spontaneous recovery rate of vocal fold mobility. Retrospective case series at single tertiary referral center between 2002 and 2015. 141 patients were included who underwent laryngology interventions (micronized acellular dermis injection laryngoplasty and/or type 1 thyroplasty) to treat symptomatic UVFP diagnosed subsequent to cardiothoracic surgery. Pulmonary procedures were most often associated with UVFP (n=50/141; 35.5%). 87.2% had left-sided paralysis (n=123/141). Median time to diagnosis was 42days (x¯=114±348). Over time, UVFP was diagnosed progressively earlier after cardiothoracic surgery. 63.4% of patients (n=95/141) underwent injection laryngoplasty as their initial intervention with median time from diagnosis to injection of 11days (x¯=29.6±54). 41.1% (n=58/141) ultimately underwent type 1 thyroplasty at a median of 232.5days (x¯=367±510.2) after cardiothoracic surgery. 10.2% (n=9/88) of those with adequate follow-up recovered full vocal fold mobility. Many cardiothoracic procedures are associated with symptomatic UVFP, predominantly left-sided. Our data showed poor recovery of vocal fold mobility relative to other studies. Early diagnosis and potential surgical medialization is important in the care of these patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Dysphonia is considered a major symptom of unilateral vocal fold paralysis (UVFP). Besides this, many patients complain of further symptoms such as dysphagia and dyspnea, which might not be expected to such an extent. The aim of this survey was to elucidate these symptoms in a cohort of patients with UVFP. Sixty-three patients (22 men, 41 women) suffering from UVFP were interviewed. Therefore we developed a questionnaire dealing with each of the three symptom categories: voice production, swallowing and breathing. All of the surveyed patients reported voice impairment, almost 60% complained of swallowing problems after the onset of paralysis. Seventy-five percent reported a subjectively impaired breathing sensation, not just phonatory dyspnea but during everyday physical activity as well. Our study revealed a certain discrepancy between objectively assessed laryngoscopic findings and subjective symptoms. A majority of patients suffered from an impairment in each of the three laryngeal functions (dysphonia, dysphagia and dyspnea). The latter two differ from the classic approach to this condition but must be considered as well in clinical diagnostics and therapy. Copyright © 2010 S. Karger AG, Basel.

    Thyrotoxic periodic paralysis (TPP) is a complication of hyperthyroidism. We describe two patients with TPP. A 26-year-old man from Vietnam had weight loss, tachycardia, palpitations and heat intolerance for five months. Episodic leg and arm weakness developed three months after debut of symptoms. The second patient, a 23-year old woman from the Philippines, had had episodic leg weakness in the evenings after dinner for three weeks. Her attacks resolved spontaneously overnight. Physical examination of both patients revealed tachycardia and symmetrical proximal weakness involving both arms and legs. ECG and electrolyte analysis indicated a severe hypokalaemia; thyroid function tests showed hyperthyroidism. Both patients were diagnosed as having Graves' thyrotoxicosis and TPP. They were initially treated with propranolol and subsequently with carbimazole. The first patient had recurrence of thyrotoxicosis and paralysis after 16 months, whereas the second patient has remained symptom-free. TPP is most common in Asian males, very few cases are reported in females. In Western countries TPP is rare, but with increasing immigration, TPP is likely to occur more frequently.

    Vocal cord paralysis is a relatively common entity, usually resulting from a pathologic process of the vagus nerve or its recurrent larynegeal branch. It is rarely caused by intralargngeal lesions. Four teen patients with recurrent laryngeal nerve paralysis (RLNP) were evaluated by laryngography, computed tomography (CT), or both. In the evaluation of the paramedian cord, CT was limited in its ability to differentiate between tumor or RLNP as the cause of the fixed cord, but it yielded more information than laryngography on the structural abnormalities of the larynx and pre-epiglottic and paralaryngeal spaces. Laryngography revealed distinct features of RLNP and is the procedure of choice for evaluation of functional abnormalities of the larynx until further experience with faster CT scanners and dynamic scanning of the larynx is gained

    A 61-year-old man with obstructive sleep apnea syndrome and normal BMI complained of dyspnea. Nasofibroscopy revealed a global and major oedema of the glottis and supraglottis and also a paralysis of the left vocal fold. CT-scan pointed out a spontaneous hyperdensity of the left arytenoid cartilage. A tracheostomy was performed. Clinical examination revealed large hands and macroglossy with high IGF1 rate. MRI confirmed a supracentimetric pituitary adenoma. To our knowledge, this is the first description of a case of acute respiratory distress due to unilateral larynx paralysis leading to acromegaly diagnosis. This is due to submucosal hypertrophy and vocal cord immobility. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    For a treatment of facial paralysis, suture suspension of soft tissue is considered effective due to its less invasiveness and relatively simple technique, with minimal bruising and rapid recovery. However, suture suspension effect may not last for a long period of time. We obtained good outcome with temporary static suture suspension in 5 cases of severe facial paralysis in the intervening period between the onset of paralysis and expected spontaneous recovery. We used the S-S Cable Suture (Medical U&A, Tokyo, Japan), which was based on the modification of previously established method using the Gore-Tex cable suture originally reported by Sasaki et al in 2002. Because of the ease of technique and relatively strong lifting capability of the malar pad, we recommend it as a useful procedure for a patient suffering acute facial paralysis with possible spontaneous recovery for an improved quality of life by the quick elimination of facial distortion.

    Life expectancy for people with spinal cord injury has shown a marked increase due to modern advances in treatment methods and in neuro-urology. However, since life expectancy of people with paralysis increases, the risk of developing of urinary bladder cancer is gaining importance. Single-centre retrospective evaluation of patient data with spinal cord injuries and proven urinary bladder cancer and summary of the literature. Between 1998 and 2014, 24 (3 female, 21 male) out of a total of 6599 patients with spinal cord injury were diagnosed with bladder cancer. The average age at bladder cancer diagnosis was 57.67 years, which is well below the average for bladder cancer cases in the general population (male: 73, female: 77). All but one patient had a latency period between the onset of the spinal paralysis and tumour diagnosis of more than 10 years. The median latency was 29.83 years. The median survival for these patients was 11.5 months. Of the 24 patients, 19 (79%) had muscle invasive bladder cancer at ≥T2 at the time of diagnosis. The type of neurogenic bladder (neurogenic detrusor overactivity or acontractility) and the form of bladder drainage do not appear to influence the risk. Long-term indwelling catheter drainage played only a minor role in the investigated patients. The significantly younger age at onset and the frequency of invasive tumours at diagnosis indicate that spinal cord injury influences bladder cancer risk and prognosis as well. Early detection of bladder cancer in patients with spinal cord injury remains a challenge.

    Diagnosis and management of peripheral nerve injury is complicated by the inability to assess microstructural features of injured nerve fibers via clinical examination and electrophysiology. Diffusion tensor imaging (DTI) has been shown to accurately detect nerve injury and regeneration in crush models of peripheral nerve injury, but no prior studies have been conducted on nerve transection, a surgical emergency that can lead to permanent weakness or paralysis. Acute sciatic nerve injuries were performed microsurgically to produce multiple grades of nerve transection in rats that were harvested 1 hour after surgery. High-resolution diffusion tensor images from ex vivo sciatic nerves were obtained using diffusion-weighted spin-echo acquisitions at 4.7 T. Fractional anisotropy was significantly reduced at the injury sites of transected rats compared with sham rats. Additionally, minor eigenvalues and radial diffusivity were profoundly elevated at all injury sites and were negatively correlated to the degree of injury. Diffusion tensor tractography showed discontinuities at all injury sites and significantly reduced continuous tract counts. These findings demonstrate that high-resolution DTI is a promising tool for acute diagnosis and grading of traumatic peripheral nerve injuries.

  19. Onset and effectiveness of rocuronium for rapid onset of paralysis in patients with major burns: priming or large bolus

    Han, T.-H.; Martyn, J. A. J.

    2009-01-01

    Background Burn injury leads to resistance to the effects of non-depolarizing muscle relaxants. We tested the hypothesis that a larger bolus dose is as effective as priming for rapid onset of paralysis after burns. Methods Ninety adults, aged 18–59 yr with 40 (2)% [mean (se)] burn and 30 (2) days after injury, received rocuronium as a priming dose followed by bolus (0.06+0.94 mg kg−1), or single bolus of either 1.0 or 1.5 mg kg−1. Sixty-one non-burned, receiving 1.0 mg kg−1 as a primed (0.06+0.94 mg kg−1) or full bolus dose, served as controls. Acceleromyography measured the onset times. Results Priming when compared with 1.0 mg kg−1 bolus in burned patients shortened the time to first appearance of twitch depression (30 vs 45 s, P<0.05) and time to maximum twitch inhibition (135 vs 210 s, P<0.05). The onset times between priming and higher bolus dose (1.5 mg kg−1) were not different (30 vs 30 s for first twitch depression and 135 vs 135 s for maximal depression, respectively). The onset times in controls, however, were significantly (P<0.05) faster than burns both for priming and for full bolus (15 and 15 s, respectively, for first twitch depression and 75 and 75 s for maximal depression). Priming caused respiratory distress in 10% of patients in both groups. Intubating conditions in burns were significantly better with 1.5 mg kg−1 than with priming or full 1.0 mg kg−1 bolus. Conclusions A dose of 1.5 mg kg−1 not only produces an initial onset of paralysis as early as 30 s, which we speculate could be a reasonable onset time for relief of laryngospasm, but also has an onset as fast as priming with superior intubating conditions and no respiratory side-effects.

    Patients with longstanding facial paralysis often exhibit synkinesis. Few reports describe the prevalence and factors related to the development of synkinesis after facial paralysis. Botulinum toxin type A injection is an important adjunct treatment for facial paralysis-induced asymmetry and synkinesis. The authors assessed the clinical and epidemiologic characteristics of patients with sequelae of facial paralysis treated with botulinum toxin type A injections to evaluate the prevalence of synkinesis and related factors. A total of 353 patients (age, 4 to 84 years; 245 female patients) with longstanding facial paralysis underwent 2312 botulinum toxin type A injections during an 11-year follow-up. Doses used over the years, previous treatments (electrical stimulation, operations), and how they correlated to postparalysis and postreanimation synkinesis were analyzed. There was a significant association between cause and surgery. Most patients with facial paralysis caused by a congenital defect, trauma, or a tumor underwent reanimation. There were no sex- or synkinesis-related differences in the doses used, but the doses were higher in the reanimation group than in the no-surgery group. Synkinesis was found in 196 patients; 148 (41.9 percent) presented with postparalysis synkinesis (oro-ocular, oculo-oral) and 58 (16.4 percent) presented with postreanimation synkinesis. Ten patients presented with both types. This study determined the high prevalence (55.5 percent) of synkinesis in patients with longstanding facial paralysis. Postparalysis synkinesis was positively associated with infectious and idiopathic causes, electrical stimulation, facial nerve decompression, and no requirement for surgery. Postreanimation synkinesis was present in 28.2 percent of reanimated patients and was significantly associated with microsurgical flaps, transfacial nerve grafting, masseteric-facial anastomosis, and temporalis muscle transfers.

    Although in most cases Bell palsy resolves spontaneously, approximately one-third of patients will present sequela including facial synkinesis and paresis. Currently, the techniques available for reanimation of these patients include hypoglossal nerve transposition, free muscle transfer, and cross-face nerve grafting (CFNG). Between December 2008 and March 2012, eight patients with incomplete unilateral facial paralysis were reanimated with two-stage CFNG. Gender, age at surgery, etiology of paralysis denervation time, donor and recipient nerves, presence of facial synkinesis, and follow-up were registered. Commissural excursion and velocity and patient satisfaction were evaluated with the FACIAL CLIMA and a questionnaire, respectively. Mean age at surgery was 33.8 ± 11.5 years; mean time of denervation was 96.6 ± 109.8 months. No complications requiring surgery were registered. Follow-up period ranged from 7 to 33 months with a mean of 19 ± 9.7 months. FACIAL CLIMA showed improvement of both commissural excursion and velocity greater than 75% in 4 patients, greater than 50% in 2 patients, and less than 50% in the remaining two patients. Qualitative evaluation revealed a high grade of satisfaction in six patients (75%). Two-stage CFNG is a reliable technique for reanimation of incomplete facial paralysis with a high grade of patient satisfaction.

    Full Text Available Abstract Background According to some reports, left hemidiaphragmatic paralysis due to phrenic nerve injury may occur following cardiac surgery. The purpose of this study was to document the effects on phrenic nerve injury of whole body hypothermia, use of ice-slush around the heart and mammary artery harvesting. Methods Electrophysiology of phrenic nerves was studied bilaterally in 78 subjects before and three weeks after cardiac or peripheral vascular surgery. In 49 patients, coronary artery bypass grafting (CABG and heart valve replacement with moderate hypothermic (mean 28°C cardiopulmonary bypass (CPB were performed. In the other 29, CABG with beating heart was performed, or, in several cases, peripheral vascular surgery with normothermia. Results In all patients, measurements of bilateral phrenic nerve function were within normal limits before surgery. Three weeks after surgery, left phrenic nerve function was absent in five patients in the CPB and hypothermia group (3 in CABG and 2 in valve replacement. No phrenic nerve dysfunction was observed after surgery in the CABG with beating heart (no CPB or the peripheral vascular groups. Except in the five patients with left phrenic nerve paralysis, mean phrenic nerve conduction latency time (ms and amplitude (mV did not differ statistically before and after surgery in either group (p > 0.05. Conclusions Our results indicate that CPB with hypothermia and local ice-slush application around the heart play a role in phrenic nerve injury following cardiac surgery. Furthermore, phrenic nerve injury during cardiac surgery occurred in 10.2 % of our patients (CABG with CPB plus valve surgery.

  5. Change to earlier surgical interventions: contemporary management of unilateral vocal fold paralysis.

    Science.gov (United States)

    Costello, Declan

    2015-06-01

    The management of unilateral vocal fold paralysis has undergone significant changes in the last 2 decades. This has largely been made possible by advances in endoscope technology and new injectable materials. This article will cover the main changes in management of patients with unilateral vocal fold paralysis and summarize the recent literature in relation to early intervention in this group. Several recent studies have suggested that early vocal fold injection medialization reduces the likelihood of needing open laryngeal framework surgery in future. Early injection medialization appears to give good long-term results with few complications and minimizes the need for future laryngeal framework surgery. It should be considered in centres wherein the equipment and trained staff are available.

    The purpose of this case report is to describe a therapeutic intervention for peroneal nerve paralysis involving the sciatic nerve. A 24-year-old man presented with peroneal nerve paralysis with decreased sensation, severe pain in the popliteal fossa, and steppage gait, which occurred 3 days prior to the consultation. Magnetic resonance imaging and electromyography confirmed lumbar disk herniation with sciatic common peroneal nerve entrapment in the popliteal fossa. A combined treatment protocol of spinal and fibular head manipulation and neurodynamic mobilization including soft tissue work of the psoas and hamstring muscles was performed. Outcome measures were assessed at pretreatment, 1 week posttreatment, and 3-month follow-up and included numeric pain rating scale, range of motion, pressure pain threshold, and manual muscle testing. Treatment interventions were applied for 3 sessions over a period of 1 week. Results showed reduction of the patient's subjective pain and considerable improvement in range of motion, strength, and sensation in his left foot, which was restored to full function. A combined program of spinal and fibular head manipulation and neurodynamic mobilization reduced pain, increased range of motion and strength, and restored full function to the left leg in this patient who had severe functional impairment related to a compressed left common peroneal nerve.

    Thumb collateral ligament injuries occur frequently in the National Football League (NFL). In the general population or in recreational athletes, pure metacarpophalangeal (MCP) abduction or adduction mechanisms yield isolated ulnar collateral ligament (UCL) and radial collateral ligament (RCL) tears, respectively, while NFL athletes may sustain combined mechanism injury patterns. To evaluate the incidence of simultaneous combined thumb UCL and RCL tears among all thumb MCP collateral ligament injuries in NFL athletes on a single team. Case series; Level of evidence, 4. A retrospective review of all thumb injuries on a single NFL team from 1991 to 2014 was performed. All players with a thumb MCP collateral ligament injury were included. Collateral ligament injuries were confirmed by review of both physical examination findings and magnetic resonance imaging. Player demographics, surgical details, and return-to-play data were obtained from the team electronic medical record and surgeons' records. A total of 36 thumbs in 32 NFL players were included in the study, yielding an incidence of 1.6 thumb MCP collateral ligament injuries per year on a single NFL team. Of these, 9 thumbs (25%) had a simultaneous combined UCL and RCL tear injury pattern confirmed on both physical examination and MRI. The remaining 27 thumbs (75%) were isolated UCL injuries. All combined UCL/RCL injuries required surgery due to dysfunction from instability; 63.0% of isolated UCL injuries required surgical repair ( P = .032) due to continued pain and dysfunction from instability. Repair, when required, was delayed until the end of the season. All players with combined UCL/RCL injuries and isolated UCL injuries returned to play professional football the following season. Simultaneous combined thumb UCL and RCL tear is a previously undescribed injury pattern that occurred in 25% of thumb MCP collateral ligament injuries on a single NFL team over a 23-year period.

    Sexuality and intimacy are important components of health and well-being. Issues surrounding sexuality and intimacy are equally important for men and women living with physical disabilities, including spinal cord injury (SCI). Yet, women's sexuality after SCI remains largely unexamined. This article presents the findings from an in-depth qualitative investigation of the sexual and reproductive health experiences of 20 women with SCI in or around Detroit, MI. Findings echo existing literature documenting the sexual consequences of life after SCI and suggest new areas of inquiry important for better addressing sexual concerns across the lifespan. Specifically, findings suggest a need to consider the variable effects of SCI on sexual intimacy in relation to a person's developmental trajectory, the appropriate timing of sexual education, the need to expand conceptualizations of sexual intimacy, and the ways SCI may affect sexuality in later life.

    Full Text Available Purpose. To evaluate of functional and cosmetic effectiveness of lower eyelid sling technique with fascia lata graft in patients with lagophthalmos due to facial paralysis. Material and Method. Ten patients with a mean age of 55.1±19.77 years who underwent lower eyelid sling surgery with a fascia lata graft between September 2011 and January 2014 were included in this prospective study. Preoperatively and postoperatively patients were evaluated in terms of corneal epithelial defects, Schirmer’s test, and tear break-up time (TBUT. Cosmetically, vertical eyelid aperture, margin reflex distances 1 and 2 (MRD1 and MRD2 and scleral show were evaluated preoperatively and postoperatively. Results. One patient had facial paralysis on the right side whereas the other 9 patients had facial paralysis on the left side. Preoperatively, 3 patients were detected with corneal ulcer, whereas 7 patients were detected with persistent corneal epithelial defects localized in the lower half of the cornea. In the 3 patients with preoperative corneal ulcer, the ulcer recovered with corneal opacity, whereas in the 7 patients with punctate epitheliopathy, postoperative corneal transparency was obtained. Discussion. Lower eyelid sling technique with fascia lata graft is an effective technique for the repositioning of the lower eyelid and preventing the corneal complications.

These CNS injuries are not only serious health problems, but also enormous economic burden on the patients, their families, and the society at large. Studies from animal models of these CNS injuries provide insights into the multiple neuroprotective mechanisms of E2 and also suggest the possibility of translating the therapeutic efficacy of E2 in the treatment SCI, TBI, and IBI in humans in the near future. The pathophysiology of these injuries includes loss of motor function in the limbs, arms and their extremities, cognitive deficit, and many other serious consequences including life-threatening paralysis, infection, and even death. The potential application of E2 therapy to treat the CNS injuries may become a trend as the results are showing significant therapeutic benefits of E2 for neuroprotection when administered into the animal models of SCI, TBI, and IBI. This article describes the plausible mechanisms how E2 works with or without the involvement of estrogen receptors and provides an overview of the known neuroprotective effects of E2 in these three CNS injuries in different animal models. Because activation of estrogen receptors has profound implications in maintaining and also affecting normal physiology, there are notable impediments in translating E2 therapy to the clinics for neuroprotection in CNS injuries in humans. While E2 may not yet be the sole molecule for

    Conclusion: Numerous cases of trauma associated cruciate paralysis have been reported in the literature; however, there remains a strong need for further study of the condition. While certain risk factors can be elicited from currently reported studies, insignificant data exist to make any sound conclusion concerning whether surgical intervention is always the best method of treatment.

    A 64-year-old woman with diabetes mellitus was admitted to our hospital with left hemiparesis of sudden onset. A brain MRI demonstrated a cerebral infarction in the ventral part of the right lower pons. When left hemiparesis worsened, she had dislocation of the temporo-mandibular joints repeatedly. Then, her lower jaw deviated to the right when she opened her mouth. Also, there was decreased contraction of the right masseter when she clenched her teeth. These findings suggest that there was trigeminal motor paralysis on the right side resulting from involvement of the intrapontine trigeminal motor nerve. She has no history of dislocation of the temporo-mandibular joints. An X-ray film showed that the temporo-mandibular joints were intact. Thus, it is possible that deviation of the lower jaw was the cause of this dislocation. We suspect that dislocation of the temporo-mandibular joints may occur as a complication of unilateral trigeminal motor paralysis. This has not been reported to our knowledge.

    Hypnagogic and hypnopompic hallucinations are visual, tactile, auditory or other sensory events, usually brief but sometimes prolonged, that occur at the transition from wakefulness to sleep (hypnagogic) or from sleep to wakefulness (hypnopompic). Hypnagogic and hypnopompic hallucinations are often associated with sleep paralysis. Sleep paralysis occurs immediately prior to falling asleep (hypnagogic paralysis) or upon waking (hypnopompic paralysis). In 1664, the Dutch physician Isbrand Van Diemerbroeck (1609-1674) published a collection of case histories. One history with the title 'Of the Night-Mare' describes the nightly experiences of the 50-year-old woman. This case report is subject of this article. The experiences in this case could without doubt be diagnosed as sleep paralysis accompanied by hypnagogic hallucinations. This case from 1664 should be cited as the earliest detailed account of sleep paralysis associated with hypnagogic illusions and as the first observation that sleep paralysis and hypnagogic experiences occur more often in supine position of the body.

  15. Ablation of the Ferroptosis Inhibitor Glutathione Peroxidase 4 in Neurons Results in Rapid Motor Neuron Degeneration and Paralysis.

    Glutathione peroxidase 4 (GPX4), an antioxidant defense enzyme active in repairing oxidative damage to lipids, is a key inhibitor of ferroptosis, a non-apoptotic form of cell death involving lipid reactive oxygen species. Here we show that GPX4 is essential for motor neuron health and survival in vivo. Conditional ablation of Gpx4 in neurons of adult mice resulted in rapid onset and progression of paralysis and death. Pathological inspection revealed that the paralyzed mice had a dramatic degeneration of motor neurons in the spinal cord but had no overt neuron degeneration in the cerebral cortex. Consistent with the role of GPX4 as a ferroptosis inhibitor, spinal motor neuron degeneration induced by Gpx4 ablation exhibited features of ferroptosis, including no caspase-3 activation, no TUNEL staining, activation of ERKs, and elevated spinal inflammation. Supplementation with vitamin E, another inhibitor of ferroptosis, delayed the onset of paralysis and death induced by Gpx4 ablation. Also, lipid peroxidation and mitochondrial dysfunction appeared to be involved in ferroptosis of motor neurons induced by Gpx4 ablation. Taken together, the dramatic motor neuron degeneration and paralysis induced by Gpx4 ablation suggest that ferroptosis inhibition by GPX4 is essential for motor neuron health and survival in vivo. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    The objective of this study was to better define the relationship of laryngeal electromyography and video laryngostroboscopy in the diagnosis of vocal fold paralysis. Retrospective diagnostic cohort study with cross-sectional data analysis METHODS: Data were obtained from 57 patients with unilateral vocal fold paralysis who attended a large tertiary voice referral center. Electromyographic findings were classified according to recurrent laryngeal nerve, superior laryngeal nerve, and high vagal/combined lesions. Video laryngostroboscopy recordings were classified according to the position of the immobile fold into median, paramedian, lateral, and a foreshortened/hooded vocal fold. The position of the paralyzed vocal fold was then analyzed according to the lesion as determined by electromyography. The recurrent laryngeal nerve was affected in the majority of cases with left-sided lesions more common than right. Vocal fold position differed between recurrent laryngeal and combined vagal lesions. Recurrent laryngeal nerve lesions were more commonly associated with a laterally displaced immobile fold. No fold position was suggestive of a combined vagal lesion. The inter-rater reliability for determining fold position was high. Laryngeal electromyography is useful in diagnosing neuromuscular dysfunction of the larynx and best practice recommends its continued implementation along with laryngostroboscopy. While recurrent laryngeal nerve lesions are more likely to present with a lateral vocal fold, this does not occur in all cases. Such findings indicate that further unknown mechanisms contribute to fold position in unilateral paralysis. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Medialization thyroplasty was effective in improving swallowing function as well as vocal function in most cases with unilateral vocal fold paralysis. The impact of medialization thryoplasty was insufficient for the case with severe atrophy and that in which the vocal fold was fixed in the lateral position. To evaluate the impacts and limitations of medialization thyroplasty on swallowing function of the patients with unilateral vocal fold paralysis. Eight cases (mean age 68.5 years) with unilateral vocal fold paralysis chiefly complaining of swallowing disturbance were studied. All patients underwent thyroplasty type I. The causes of the paralysis were lung cancer in four cases, esophageal cancer in one case, aortic aneurysm in one case, subarachnoid hemorrhage in one case, and unknown in one case. Subjective swallowing function score, maximum phonation time (MPT), mean flow rate (MFR), amplitude perturbation quotient (APQ), and pitch perturbation quotient (PPQ) were examined pre- and postoperatively. The swallowing score improved in all except two cases. However, bilateral thryoplasty was necessary for the case with severe vocal fold atrophy and arytenoid adduction was needed for the case in which the vocal fold was fixed in the lateral position. The swallowing score, MPT, and MFR showed significant improvement after surgery.

    BACKGROUND Thyrotoxic periodic paralysis (TPP) is commonly observed in patients with acute paralysis and hyperthyroidism. However, there is a possibility of secondary causes of hypokalemia in such a setting. CASE REPORT Herein, we present the case of a 38-year-old woman with untreated hypertension and hyperthyroidism. She presented with muscle weakness, nausea, vomiting, and diarrhea since one week. The initial diagnosis was TPP. However, biochemistry tests showed hypokalemia with metabolic alkalosis and renal potassium wasting. Moreover, a suppressed plasma renin level and a high plasma aldosterone level were noted, which was suggestive of primary aldosteronism. Abdominal computed tomography confirmed this diagnosis. CONCLUSIONS Therefore, it is imperative to consider other causes of hypokalemia (apart from TPP) in a patient with hyperthyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease.

    Most temporal bone fractures result from high-energy blunt head trauma, and are frequently related to other skull fractures or to polytrauma. Fractures and displacements of ossicular chain in the middle ear represent some of the main complications of temporal bone injury, and hence they will be more deeply approached in the present article. Other types of injuries include labyrinthine fractures, dural fistula, facial nerve paralysis and extension into the carotid canal. Computed tomography plays a fundamental role in the initial evaluation of polytrauma patients, as it can help to identify important structural injuries that may lead to severe complications such as sensorineural hearing loss, conductive hearing loss, dizziness and balance dysfunction, perilymphatic fistulas, facial nerve paralysis, vascular injury and others.

    Bell's palsy (idiopathic facial paralysis) is commonly treated by physical therapy services with various therapeutic strategies and devices. There are many questions about their efficacy and effectiveness. To evaluate the efficacy of physical therapies on the outcome of Bell's palsy. We searched the Cochrane Neuromuscular Disease Group Trials Register (February 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2007), MEDLINE (January 1966 to February 2008), EMBASE (January 1980 to February 2008), LILACS (January 1982 to February 2008), PEDro (from 1929 to February 2008), and CINAHL (January 1982 to February 2008). We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. Titles and abstracts identified from the register were scrutinized. The assessment of methodological quality took into account secure method of randomisation, allocation concealment, observer blinding, patient blinding, differences at baseline of the experimental groups, and completeness of follow-up. Data were extracted using a specially constructed data extraction form. Separate subgroup analyses of participants with more and less severe disability were undertaken. The search identified 45 potentially relevant articles. Six studies met the inclusion criteria. Three trials studied the efficacy of electrostimulation (294 participants) and three exercises (253 participants). Neither treatment produced significantly more improvement than the control treatment or no treatment. There was limited evidence that improvement began earlier in the exercise group. There is no evidence of significant

    Despite the capacity of Schwann cells to support peripheral nerve regeneration, functional recovery after nerve injuries is frequently poor, especially for proximal injuries that require regenerating axons to grow over long distances to reinnervate distal targets. Nerve transfers, where small fascicles from an adjacent intact nerve are coapted to the nerve stump of a nearby denervated muscle, allow for functional return but at the expense of reduced numbers of innervating nerves. A 1-hour period of 20 Hz electrical nerve stimulation via electrodes proximal to an injury site accelerates axon outgrowth to hasten target reinnervation in rats and humans, even after delayed surgery. A novel strategy of enticing donor axons from an otherwise intact nerve to grow through small nerve grafts (cross-bridges) into a denervated nerve stump, promotes improved axon regeneration after delayed nerve repair. The efficacy of this technique has been demonstrated in a rat model and is now in clinical use in patients undergoing cross-face nerve grafting for facial paralysis. In conclusion, brief electrical stimulation, combined with the surgical technique of promoting the regeneration of some donor axons to 'protect' chronically denervated Schwann cells, improves nerve regeneration and, in turn, functional outcomes in the management of peripheral nerve injuries.

    A 44 year old man with longstanding diabetes mellitus gave a 6-month history of periodic attacks of flaccid quadriplegia. Following one of these episodes he was admitted for assessment. In view of persistent hyperkalaemia, hypoadrenalism was suspected and Addison's disease was confirmed biochemically. Adrenal replacement therapy restored the potassium levels to normal and resulted in no further attacks of paralysis. PMID:2594601

    We performed technetium-99m-hexamethylpropylene- amineoxime (Tc-HMPAO) single photon emission computed tomography in two patients with prolonged hemiconvulsions followed by transient hemiparesis (Todd`s paralysis). In both cases, a prolonged post-ictal cerebral hyperperfusion state of approximately 24 h was observed, even after the neurological deficits had resolved. The cerebral hyperperfusion in both cases was of much longer duration than that in previously reported cases of single and uncomplicated focal seizures. The prolonged cerebral hyperperfusion might have been due to impairment of the cerebrovascular autoregulation in seizures followed by Todd`s paralysis. (orig.) With 2 figs., 9 refs.

    Patent ductus arteriosus (PDA) is a common problem in preterm newborns. Left vocal cord paralysis (LVCP) can complicate surgical closure if the recurrent nerve is damaged. A retrospective case series study was conducted on preterm babies diagnosed with PDA in our unit from 1999 to 2013. Their clinical features and treatment complications were reviewed. In those patients that received surgical treatment a telephone questionnaire on the symptoms of LVCP symptoms was completed, and laryncoscopy examination offered. A total of 88 subjects diagnosed with PDA were found, of whom 13.64% (12/88) needed surgery. These patients had a lower gestational age and birth weight. They required mechanical ventilation more frequently, and they had more complications such as, diaphragmatic paralysis, bronchopulmonary dysplasia and intraventricular hemorrhage. One third (3/9) of the surgically treated patients had LVCP, and all of them had dysphonia (100% vs. 16.7%, p=.05). LVCP is a common complication of PDA surgery. Further studies are needed to determine its risk factors and its short and long-term consequences. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

    Chronic bee paralysis virus (CBPV) infection causes chronic paralysis and loss of workers in honey bee colonies around the world. Although CBPV shows a worldwide distribution, it had not been molecularly detected in Japan. Our investigation of Apis mellifera and Apis cerana japonica colonies with RT-PCR has revealed CBPV infection in A. mellifera but not A. c. japonica colonies in Japan. The prevalence of CBPV is low compared with that of other viruses: deformed wing virus (DWV), black queen cell virus (BQCV), Israel acute paralysis virus (IAPV), and sac brood virus (SBV), previously reported in Japan. Because of its low prevalence (5.6%) in A. mellifera colonies, the incidence of colony losses by CBPV infection must be sporadic in Japan. The presence of the (-) strand RNA in dying workers suggests that CBPV infection and replication may contribute to their symptoms. Phylogenetic analysis demonstrates a geographic separation of Japanese isolates from European, Uruguayan, and mainland US isolates. The lack of major exchange of honey bees between Europe/mainland US and Japan for the recent 26 years (1985-2010) may have resulted in the geographic separation of Japanese CBPV isolates.

    The progressive supra-nuclear paralysis (PSP) or Steele-Richardson-Olszewsky’s syndrome is a strange, degenerative illness produced by the deterioration and gradual death of brain selected areas. We present the case of a female patient, aged 80 years, who refers postural instability, frequent falls and cognitive dysfunctions. She also presents stiffness in retrocollis in the back of the neck, fall of eyelids, left hand shaking, dysarthric and incoherent language, and shaking of both hands in coins counting. The cardiovascular examination showed 2nd increased beat, systolic murmur III/IV in mitral focus, AT 160/90 mm of Hg, edemas in both inferior members, hearth frequency of 110 beats/min., and jugular ingurgitation. The rest of the physical examination was normal. The etiologic diagnosis was progressive supranuclear paralysis and dilated cardiomyopathy. The tau protein is important in the maintenance of the neuronal morphology through microtubules formation, the different proportions and locations, causing the Richardson’s syndrome. The most common symptoms of this entity are postural instability and frequent falls, dysarthria, hypokinesia and visual alterations. Magnetic resonance and functional neuroimaging help the diagnosis.

    Background  Phrenic nerve reconstruction has been evaluated as a method of restoring functional activity and may be an effective alternative to diaphragm plication. Longer follow-up and a larger cohort for analysis are necessary to confirm the efficacy of this procedure for diaphragmatic paralysis. Methods  A total of 180 patients treated with phrenic nerve reconstruction for chronic diaphragmatic paralysis were followed for a median 2.7 years. Assessment parameters included: 36-Item Short Form Health Survey (SF-36) physical functioning survey, spirometry, chest fluoroscopy, electrodiagnostic evaluation, a five-item questionnaire to assess specific functional issues, and overall patient-reported outcome. Results  Overall, 134 males and 46 females with an average age of 56 years (range: 10-79 years) were treated. Mean baseline percent predicted values for forced expiratory volume in 1 second, forced vital capacity, vital capacity, and total lung capacity, were 61, 63, 67, and 75%, respectively. The corresponding percent improvements in percent predicted values were: 11, 6, 9, and 13% ( p ≤ 0.01; ≤ 0.01; ≤ 0.05; ≤ 0.01). Mean preoperative SF-36 physical functioning survey scores were 39%, and an improvement to 65% was demonstrated following surgery ( p  ≤ 0.0001). Nerve conduction latency, improved by an average 23% ( p  ≤ 0.005), and there was a corresponding 125% increase in diaphragm motor amplitude ( p  ≤ 0.0001). A total of 89% of patients reported an overall improvement in breathing function. Conclusion  Long-term assessment of phrenic nerve reconstruction for diaphragmatic paralysis indicates functional correction and symptomatic relief.

    The current study examines cultural explanations regarding sleep paralysis (SP) in Italy. The study explores (1) whether the phenomenology of SP generates culturally specific interpretations and causal explanations and (2) what are the beliefs and local traditions associated with such cultural explanations. The participants were Italian nationals from the general population (n = 68) recruited in the region of Abruzzo, Italy. All participants had experienced at least one lifetime episode of SP. The sleep paralysis experiences and phenomenology questionnaire were orally administered to participants. We found a multilayered cultural interpretation of SP, namely the Pandafeche attack, associated with various supernatural beliefs. Thirty-eight percent of participants believed that this supernatural being, the Pandafeche-often referred to as an evil witch, sometimes as a ghost-like spirit or a terrifying humanoid cat-might have caused their SP. Twenty-four percent of all participants sensed the Pandafeche was present during their SP. Strategies to prevent Pandafeche attack included sleeping in supine position, placing a broom by the bedroom door, or putting a pile of sand by the bed. Case studies are presented to illustrate the study findings. The Pandafeche attack thus constitutes a culturally specific, supernatural interpretation of the phenomenology of SP in the Abruzzo region of Italy.

    Necrotizing sialometaplasia is a benign inflammatory lesion involving most frequently the minor salivary gland of the hard palate. Involvement of the parotid gland is rare, involvement of the parotid gland associated with facial palsy is exceptional. A 56-year-old male patient with Marfan syndrome presented with swelling and inflammation of the left parotid gland associated with progressively complete facial nerve paralysis. CT scan and MRI showed a parotid collection with hyper signal of the nearest tissues associated with erosion of the styloid process. A malignant tumor was suspected. The histological examination of a biopsy showed a lobulocentric process with necrosis, squamous metaplasia, and inflammation. The immunohistochemical examination supported a final diagnosis of necrotizing sialometaplasia. Necrotizing sialometaplasia of the parotid gland associated with facial nerve paralysis presents like a malignant neoplasm, both clinically and histologically. Only advanced immunohistochemical examination can really confirm the diagnosis. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Fluorodeoxyglucose-positron emission tomography (FDG-PET) is employed to decide the treatment strategy for malignant tumors clinically. Meanwhile, glucose metabolism is enhanced in the exercise of muscles. Because vocal folds always conduct glucose metabolism by phonation and swallowing, physiological accumulation of FDG may be found in the normal larynx. In this study we examined FDG accumulation in the larynx of patients with unilateral vocal fold paralysis established by endoscope. FDG-PET/CT was taken one hour after the FDG administration (early image) and again two hours later (delayed image). All patients had no chance to utter after the FDG administration. In 25 of the 28 patients with unilateral vocal fold paralysis, standardized uptake value (SUV) max was higher, by visual inspection, in the normal side of the larynx than in the paralyzed side. None of the 3 patients in whom no accumulation was seen on the non-paralyzed side had malignant disease. In both images, SUV max of the normal side was significantly higher than paralyzed side (p<0.01). In the delayed images, accumulation of FDG was significantly higher than that in the early images (p<0.01). We believe that strong FDG accumulation in the normal side of the larynx of patients with unilateral vocal fold paralysis may owe to high glucose metabolism of the vocal muscles from muscle hyperkinesis. We conclude that unilateral accumulation in the larynx suggests not only cancer of that same side of the larynx but also paralysis of the other side. (author)

    The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors. To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma. Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis. Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia. No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. ©2015 American Association of Critical-Care Nurses.

  18. “Don’t Think Paralysis Takes Away Your Womanhood”: Sexual Intimacy After Spinal Cord Injury

    2015-01-01

    Sexuality and intimacy are important components of health and well-being. Issues surrounding sexuality and intimacy are equally important for men and women living with physical disabilities, including spinal cord injury (SCI). Yet, women’s sexuality after SCI remains largely unexamined. This article presents the findings from an in-depth qualitative investigation of the sexual and reproductive health experiences of 20 women with SCI in or around Detroit, MI. Findings echo existing literature documenting the sexual consequences of life after SCI and suggest new areas of inquiry important for better addressing sexual concerns across the lifespan. Specifically, findings suggest a need to consider the variable effects of SCI on sexual intimacy in relation to a person’s developmental trajectory, the appropriate timing of sexual education, the need to expand conceptualizations of sexual intimacy, and the ways SCI may affect sexuality in later life.

    2001-01-01

    The case of an 8-month-old boy with bilateral diaphragmatic paralysis after surgical reoperation for congenital heart disease is presented. In order to avoid repeated intubation and long-term mechanical ventilation or tracheotomy, we used nasal mask continuous positive airway pressure (CPAP) as an alternative method for assisted ventilation. Within 24 hours the boy accepted the nasal mask and symptoms such as dyspnea and sweating disappeared. Respiratory movements became regular and oxygen saturation increased. Nasal mask CPAP may serve as an alternative treatment of bilateral diaphragmatic paralysis in infants, thereby avoiding tracheotomy or long-term mechanical ventilation.

    Clinical, radiological, physiological, and lung imaging findings from a patient with paralysis of the diaphragm are described. Dyspnea, hypoxemia and hypercapnia increased when the patient changed from the upright to the supine positions. Ventilation (V) and perfusion (P) images of the right lung appeared to be relatively normal and remained nearly the same in the upright and supine positions. In contrast, V/P images of the left lung were smaller than those of the right lung in the upright position and decreased further in the supine position. In addition, the size of the ventilation image was much smaller than that of the perfusion

    The goal of this study was to investigate the acute and chronic effects of paralysis induced by spinal cord section or sciatic neurotomy on bone blood flow in the rat. Regional bone blood flow was measured in the early stage with the hydrogen washout technique and the change of whole bone blood flow was measured in the early and the late stages with the radioactive microsphere technique. Four to 6 h after cordotomy at the level of the 13th thoracic vertebra, the regional bone blood flow in the denervated tibia increased significantly (p less than 0.01). After hemicordotomy with rhizotomy at the same level, the regional bone blood flow in the denervated tibia increased significantly (p less than 0.05) 6 h postoperatively. The whole bone blood flow in the denervated tibia had also increased significantly (p less than 0.05) at 6 h and at 4 and 12 weeks postoperatively. After sciatic neurotomy, the regional and the whole bone blood flow in the paralytic tibia did not change significantly. The present study demonstrated that monoplegic paralysis caused an increase in bone blood flow in the denervated hind limb from a very early stage. It was suggested that the spinal nervous system contributed to the control of bone blood flow

  5. Contralateral botulinum toxin injection to improve facial asymmetry after acute facial paralysis.

    Science.gov (United States)

    Kim, Jin

    2013-02-01

    The application of botulinum toxin to the healthy side of the face in patients with long-standing facial paralysis has been shown to be a minimally invasive technique that improves facial symmetry at rest and during facial motion, but our experience using botulinum toxin therapy for facial sequelae prompted the idea that botulinum toxin might be useful in acute cases of facial paralysis, leading to improve facial asymmetry. In cases in which medical or surgical treatment options are limited because of existing medical problems or advanced age, most patients with acute facial palsy are advised to await spontaneous recovery or are informed that no effective intervention exists. The purpose of this study was to evaluate the effect of botulinum toxin treatment for facial asymmetry in 18 patients after acute facial palsy who could not be optimally treated by medical or surgical management because of severe medical or other problems. From 2009 to 2011, nine patients with Bell's palsy, 5 with herpes zoster oticus and 4 with traumatic facial palsy (10 men and 8 women; age range, 22-82 yr; mean, 50.8 yr) participated in this study. Botulinum toxin A (Botox; Allergan Incorporated, Irvine, CA, USA) was injected using a tuberculin syringe with a 27-gauge needle. The amount injected per site varied from 2.5 to 3 U, and the total dose used per patient was 32 to 68 U (mean, 47.5 +/- 8.4 U). After administration of a single dose of botulinum toxin A on the nonparalyzed side of 18 patients with acute facial paralysis, marked relief of facial asymmetry was observed in 8 patients within 1 month of injection. Decreased facial asymmetry and strengthened facial function on the paralyzed side led to an increased HB and SB grade within 6 months after injection. Use of botulinum toxin after acute facial palsy cases is of great value. Such therapy decreases the relative hyperkinesis contralateral to the paralysis, leading to greater symmetric function. Especially in patients with medical

    Full Text Available Licorice is the root of Glycyrrhiza glabra, which has a herbal ingredient, glycyrrhizic acid. Excessive intake of licorice may cause a hypermineralocorticoidism-like syndrome characterized by sodium and water retention, hypokalemia, hypertension, metabolic alkalosis, low-renin activity, and hypoaldosteronism. In this paper, an 34 years old man who admitted to the emergency department with respiratory failure and marked muscle weakness of all extremities that progressed to paralysis after excessive intake of licorice syrup was presented. It was aimed to draw attention to the necessity of questioning whether there is excessive intake of licorice or not in patients who admitted to emergency department with paralysis and dyspnea. Plasma potassium concentration of the patient was 1.4 mmol/L. The patient\\'s respiratory distress and loss of muscle strength recovered completely after potassium replacement.

    Objective: To assess the prophylactic measures of paraplegia and paralysis after endovascular graft exclusion (EVE) for Stanford B thoracic aortic dissections (TAD). Methods: The records of 116 consecutive patients undergoing endovascular TAD repair from 1998 to 2001 were retrospectively reviewed. Steroids were administrated postoperatively in high risk patients likely to be candidates for paraplegia or paralysis. Results: No paraplegia or paralysis occurred postoperatively in all cases, including the patient undergone selective spinal artery angiography (SSAA). Conclusions: Transluminal repair can avoid spinal cord ischemia due to aortic cross-clamping, there is still a risk of spinal cord injury caused by occlusion of intercostal arteries under the cover of endograft. A combination of the prophylactic measures, including SSAA and steroids, have been able to reduce the risk of paraplegia and paralysis. A graft-stent of appropriate length is the key point of this procedure

    2007-01-01

    Locomotor impairments after spinal cord injury (SCI) are often assessed using open-field rating scales. These tasks have the advantage of spanning the range from complete paralysis to normal walking; however, they lack sensitivity at specific levels of recovery. Additionally, most supplemental assessments were developed in rats, not mice. For example, the horizontal ladder beam has been used to measure recovery in the rat after SCI. This parametric task results in a videotaped archival record...

  10. Hypokalemic paralysis in a middle-aged female with classic Bartter syndrome.

    2014-02-01

    Inherited classic Bartter syndrome (cBS) is an autosomal recessive renal tubular disorder resulting from inactivating mutations in the asolateral chloride channel (C1C-Kb) and usually presents in early infancy or childhood with mild to moderate hypokalemia. Profound hypokalemic paralysis in patients with cBS is extremely rare, especially in middle age. A 45-year-old Chinese female patient was referred for evaluation of chronic severe hypokalemia despite regular K+ supplementation (1 mmol/kg/d). She had had two episodes of muscle paralysis due to severe hypokalemia (K+ 1.9 - 2.1 mmol/l) in the past 3 years. She denied vomiting, diarrhea, or the use of laxatives or diuretics. Her blood pressure was normal. Biochemical studies showed hypokalemia (K+ 2.5 mmol/l) with renal potassium wasting, metabolic alkalosis (HCO3- 32 mmol/l), normomagnesemia (Mg2+ 0.8 mmol/l), hypercalciuria (calcium to creatinine ratio 0.5 mmol/mmol; normal < 0.22 mmol/mol), high plasma renin activity, but normal plasma aldosterone concentration. Abdominal sonography revealed neither renal stones nor nephrocalcinosis. Acquired causes of cBS such as autoimmune disease and drugs were all excluded. Molecular analysis of the CLCNKB gene, encoding ClC-Kb, and SLC12A3, encoding the thiazide-sensitive sodium chloride cotransporter (NCC), revealed compound heterozygous mutations in CLCNKB (L335P and G470E) inherited from her parents; her SLC12A3 was normal. These two mutations were not identified in 100 healthy subjects. Her plasma K+ concentration rose to 3 - 3.5 mmol/l after the addition of spironolactone. Inherited cBS may present with hypokalemic paralysis and should be considered in adult patients with hypokalemia and metabolic alkalosis.

    Full Text Available A case of isolated velopalatine paralysis in an 8-year-old boy is presented. The symptoms were sudden-onset of nasal speech, regurgitation of liquids into the nose and dysphagia. Brain MRI and cerebrospinal fluid examination were normal. Infectious serologies disclosed an antibody arrangement towards parvovirus B19 that was typical of recent infection. In the absence of other positive data, the possibility of a correlation between the tenth nerve palsy and parvovirus infection is discussed.

    Professor DONG Gui-rong's theoretical principle and manipulation points for peripheral facial paralysis were introduced in details from the angels of syndrome differentiation, timing, acupoint prescription and needling methods. For the syndrome differentiation and timing, the professor emphasized to check the treatment timing and follow the symptoms, which should be treated by stages, besides, it was necessary to find and distinguish the reason and nature of diseases to have a combined treatment of tendons and muscles. For the acupoint prescription and needling methods, he has proposed that the acupoints selection should be compatible of distal and lacal, and made a best of Baihui (GV 20) to regulate the whole yang qi, also he has paid much attention to the needling methods and staging treatment. Under the consideration of late stage of peripheral facial paralysis, based on syndrome differentiation Back-shu points have been selected to regulate zang-fu function, should achieve much better therapeutic effect.

    Lerner, E. Brooke; Roberts, Jennifer; Guse, Clare E.; Shah, Manish N.; Swor, Robert; Cushman, Jeremy T.; Blatt, Alan; Jurkovich, Gregory J.; Brasel, Karen

    2013-01-01

    Objective Our objective was to determine the predictive value of the anatomic step of the 2011 Field Triage Decision Scheme for identifying trauma center need. Methods EMS providers caring for injured adults transported to regional trauma centers in 3 midsized communities were interviewed over two years. Patients were included, regardless of injury severity, if they were at least 18 years old and were transported by EMS with a mechanism of injury that was an assault, motor vehicle or motorcycle crash, fall, or pedestrian or bicyclist struck. The interview was conducted upon ED arrival and collected physiologic condition and anatomic injury data. Patients who met the physiologic criteria were excluded. Trauma center need was defined as non-orthopedic surgery within 24 hours, intensive care unit admission, or death prior to hospital discharge. Data were analyzed by calculating descriptive statistics including positive likelihood ratios (+LR) with 95% confidence intervals. Results 11,892 interviews were conducted. One was excluded because of missing outcome data and 1,274 were excluded because they met the physiologic step. EMS providers identified 1,167 cases that met the anatomic criteria, of which 307 (26%) needed the resources of a trauma center (38% sensitivity, 91% specificity, +LR 4.4; CI: 3.9 - 4.9). Criteria with a +LR ≥5 were flail chest (9.0; CI: 4.1 - 19.4), paralysis (6.8; CI: 4.2 - 11.2), two or more long bone fractures (6.3; CI: 4.5 - 8.9), and amputation (6.1; CI: 1.5 - 24.4). Criteria with a +LR >2 and <5 were penetrating injury (4.8; CI: 4.2 - 5.6), and skull fracture (4.8; CI: 3.0 - 7.7). Only pelvic fracture (1.9; CI: 1.3 - 2.9) had a +LR less than 2. Conclusions The anatomic step of the Field Triage Guidelines as determined by EMS providers is a reasonable tool for determining trauma center need. Use of EMS perceived pelvic fracture as an indicator for trauma center need should be re-evaluated. PMID:23627418

  15. Molecular cloning of ion channels in Felis catus that are related to periodic paralyses in man: a contribution to the understanding of the genetic susceptibility to feline neck ventroflexion and paralysis

    Directory of Open Access Journals (Sweden)

    Marlyn Zapata

    2014-07-01

    Full Text Available Neck ventroflexion in cats has different causes; however, the most common is the hypokalemia associated with flaccid paralysis secondary to chronic renal failure. In humans, the most common causes of acute flaccid paralysis are hypokalemia precipitated by thyrotoxicosis and familial forms linked to mutations in sodium, potassium, and calcium channel genes. Here, we describe the sequencing and analysis of skeletal muscle ion channels in Felis catus that could be related to periodic paralyses in humans, contributing to the understanding of the genetic susceptibility to feline neck ventroflexion and paralysis. We studied genomic DNA from eleven cats, including five animals that were hyperthyroid with hypokalemia, although only one presented with muscle weakness, and six healthy control domestic cats. We identified the ion channel ortholog genes KCNJ2, KCNJ12, KCNJ14, CACNA1S and SCN4A in the Felis catus genome, together with several polymorphic variants. Upon comparative alignment with other genomes, we found that Felis catus provides evidence for a high genomic conservation of ion channel sequences. Although we hypothesized that neck ventroflexion in cats could be associated with a thyrotoxic or familial periodic paralysis channel mutation, we did not identify any previously detected human channel mutation in the hyperthyroid cat presenting hypokalemia. However, based on the small number of affected cats in this study, we cannot yet rule out this molecular mechanism. Notwithstanding, hyperthyroidism should still be considered as a differential diagnosis in hypokalemic feline paralysis.

    To analyse the efficacy of CO(2) laser arytenoidectomy in the management of bilateral vocal cord paralysis in children. Retrospective series of 17 patients who underwent laser arytenoidectomy for bilateral vocal cord between 1995 and 2008 in a tertiary care institution. All patients had bilateral laryngeal paralysis, in isolation (n=5) or associated with concomitant airway conditions (n=12). All cases had anterior prolapse of the arytenoids with partial obstruction of the airway on inspiration. 12/17 patients (70.5%) were tracheotomy-dependant, 2/17 were in-extubatable, and 3/17 had severe airway limitation, effort dyspnea and poor sleep pattern. Main outcome measures were decannulation rate for patients with tracheotomy, occurrence of aspiration and quality of voice. The mean age was 2.8 years old. 9/12 patients with tracheotomy (75%) were decannulated with a median delay of 2 months (2 days to 18 months). Both of the intubated patients were extubated with a median delay of 36h. One of the decannulated patients who re-presented with a residual dyspnea after the arytenoidectomy was improved by a further laser cordotomy. 2/17 patients (11.7%) had post-operative persistent aspirations (with pneumopathies in one case), 5/17 patients were dysphonic, 3 improved with speech therapy and 2 with intracordal lipoinjection. Laser arytenoidectomy is effective for improving the breathing in children presenting with a bilateral vocal fold paralysis associated with obstructive arytenoid prolapse. Results are good as a first-line surgery or following laryngo-tracheal surgery. Voice outcomes are satisfactory. However, aspiration is a rare complication. Copyright (c) 2010 Elsevier Ireland Ltd.

    2012-10-01

    Full Text Available PURPOSE: Crotoxin is the major toxin of the venom of the South American rattlesnake Crotalus durissus terrificus, capable of causing a blockade of the neurotransmitters at the neuromuscular junction. The objective of this study was to appraise the action and effectiveness of the crotoxin induced paralysis of the extraocular muscle and to compare its effects with the botulinum toxin type A (BT-A. METHODS: The crotoxin, with LD50 of 1.5 µg, was injected into the superior rectus muscle in ten New Zealand rabbits. The concentration variance was 0.015 up to 150 µg. Two rabbits received 2 units of botulinum toxin type A for comparative analysis. The evaluation of the paralysis was performed using serial electromyography. After the functional recovery of the muscles, which occurred after two months, six rabbits were sacrificed for anatomopathology study. RESULTS: The animals did not show any evidence of systemic toxicity. Transitory ptosis was observed in almost every animal and remained up to fourteen days. These toxins caused immediate blockade of the electrical potentials. The recovery was gradual in the average of one month with regeneration signs evident on the electromyography. The paralysis effect of the crotoxin on the muscle was proportional to its concentration. The changes with 1.5 µg crotoxin were similar to those produced by the botulinum toxin type A. The histopathology findings were localized to the site of the injection. No signs of muscle fiber's necrosis were seen in any sample. The alterations induced by crotoxin were also proportional to the concentration and similar to botulinum toxin type A in concentration of 1.5 µg. CONCLUSION: Crotoxin was able to induce transitory paralysis of the superior rectus muscle. This effect was characterized by reduction of action potentials and non-specific signs of fibrillation. Crotoxin, in concentration of 1.5 µg was able to induce similar effects as botulinum toxin type A.

    Full Text Available The limited symptom relief and side effects of current Alzheimer's disease (AD medications warrant urgent discovery and study of new anti-AD agents. The "cholinergic hypothesis" of AD prompts us to search for plant-derived acetylcholineesterase (AChE inhibitors such as galanthamine that has been licensed in Europe for AD treatment. We used the unique amyloid β-expressing transgenic C. elegans CL4176, which exhibits paralysis when human Aβ1-42 is induced, to study two natural benzylphenethylamine alkaloids isolated from Lycoris radiata (L' Her. Herb, galanthamine and haemanthidine, and their synthetic derivatives 1,2-Di-O-acetyllycorine and 1-O-acetyllycorine for their anti-paralysis effects. Our data indicate that these Lycoris compounds effectively delay the paralysis of CL4176 worms upon temperature up-shift, and prolong the lives of these transgenic worms. Lycoris compounds were shown to significantly inhibit the gene expression of ace-1 and ace-2. Additionally, the Lycoris compounds may modulate inflammatory and stress-related gene expressions to combat the Aβ-toxicity in C. elegans.

    Before the introduction of computerized tomography (CT) there were some cases of intracerebral bleeding who were wrongly diagnosed as hypertensive encephalopathy or senile psychosis. We here report 5 cases who did not show any sign of motor paralysis. The clinical aspects of these cases were nausea and vomiting with dizziness (case 1), nausea and vomiting with slight headache (case 2), agnosia of left side with several kinds of disorientation (case 3), nausea and vomiting (case 4), and visual disturbance of right, lower quadrant (case 5). All of these cases showed no motor paralysis or abnormal reflex activities. By examination with CT each of them exhibited a high density area in the subcortical area of the right parietal lobe, the subcortical area of the right occipital lobe, the right temporal and parietal lobe, rather small portion of the left putamen and external capsule, and the subcortical area of left occipital lobe, respectively. Patients of cerebral hemorrhage without motor or sensory disturbances might often be taken for some psychic abnormality. We here have emphasized the importance of CT in such a group of patients. But for this technique, most of them would not be given adequate treatment and might be exposed to lifethreatening situations.

    Facial paralysis can contribute to disfigurement, psychological difficulties, and an inability to convey emotion via facial expression. In patients unable to perform a meaningful smile, free gracilis muscle transfer (FGMT) can often restore smile function. However, little is known about the impact on disease-specific quality of life. To determine quantitatively whether FGMT improves quality of life in patients with facial paralysis. Prospective evaluation of 154 FGMTs performed at a facial nerve center on 148 patients with facial paralysis. The Facial Clinimetric Evaluation (FaCE) survey and Facial Assessment by Computer Evaluation software (FACE-gram) were used to quantify quality-of-life improvement, oral commissure excursion, and symmetry with smile. Free gracilis muscle transfer. Change in FaCE score, oral commissure excursion, and symmetry with smile. There were 127 successful FGMTs on 124 patients and 14 failed procedures on 13 patients. Mean (SD) FaCE score increased significantly after successful FGMT (42.30 [15.9] vs 58.5 [17.60]; paired 2-tailed t test, P improved significantly in all subgroups (nonflaccid cohort, 37.8 [19.9] vs 52.9 [19.3]; P = .02; flaccid cohort, 43.1 [15.1] vs 59.6 [17.2]; P improved from a mean (SD) of 13.8 (7.46) to 4.88 (3.47) (P improvement in quality of life after FGMT in patients who could not recover a meaningful smile after facial nerve insult. Quality-of-life improvement was not statistically different between donor nerve groups or facial paralysis types.

    Full Text Available Thyrotoxic periodic paralysis (TPP is a rare complication of hyperthyroidism, with recurrent muscle paralysis and hypokalemia that are caused by an intracellular shift of potassium. TPP is relatively common in Asian males, but is extremely rare in children and adolescents, even for those of Asian descent. We describe a 16-year-old Korean adolescent presenting with a two-week history of episodic leg weakness in the morning. He showed sinus tachycardia, lower leg weakness, and hypokalemia. Thyroid function test showed hyperthyroidism, and thyroid ultrasonography revealed a diffuse enlarged thyroid with increased vascularity, consistent with Graves' disease. He was treated with β-adrenergic blocker and antithyroid drugs. He has been symptom free for one year, as his hyperthyroidism has been controlled well with antithyroid drugs. TPP should be considered in children and adolescents with acute paralysis of the lower extremities and hypokalemia.

    2013-01-28

    Bell's palsy is defined as an idiopathic peripheral facial nerve paralysis of sudden onset. It affects 11-40 persons per 100,000 per annum. Many patients recover without intervention; however, up to 30% have poor recovery of facial muscle control and experience facial disfigurement. The aim of this study was to make an overview of which pharmacological treatments have been used to improve outcomes. The available evidence from randomized controlled trials shows significant benefit from treating Bell's palsy with corticosteroids but shows no benefit from antivirals.

    Bell's palsy (idiopathic facial paralysis) is commonly treated by various physical therapy strategies and devices, but there are many questions about their efficacy. To evaluate physical therapies for Bell's palsy (idiopathic facial palsy). We searched the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2011), MEDLINE (January 1966 to February 2011), EMBASE (January 1946 to February 2011), LILACS (January 1982 to February 2011), PEDro (from 1929 to February 2011), and CINAHL (January 1982 to February 2011). We included searches in clinical trials register databases until February 2011. We selected randomised or quasi-randomised controlled trials involving any physical therapy. We included participants of any age with a diagnosis of Bell's palsy and all degrees of severity. The outcome measures were: incomplete recovery six months after randomisation, motor synkinesis, crocodile tears or facial spasm six months after onset, incomplete recovery after one year and adverse effects attributable to the intervention. Two authors independently scrutinised titles and abstracts identified from the search results. Two authors independently carried out risk of bias assessments, which , took into account secure methods of randomisation, allocation concealment, observer blinding, patient blinding, incomplete outcome data, selective outcome reporting and other bias. Two authors independently extracted data using a specially constructed data extraction form. We undertook separate subgroup analyses of participants with more and less severe disability. For this update to the original review, the search identified 65 potentially relevant articles. Twelve studies met the inclusion criteria (872 participants). Four trials studied the efficacy of electrical stimulation (313 participants), three trials studied exercises (199 participants), and five studies compared or combined some form of physical therapy

    Injury to the rotator cuff can cause irreversible changes to the structure and function of the associated muscles and bones. The temporal progression and pathomechanisms associated with these adaptations are unclear. The purpose of this study was to investigate the time course of structural muscle and osseous changes in a rat model of a massive rotator cuff tear. Supraspinatus and infraspinatus muscle architecture and biochemistry and humeral and scapular morphological parameters were measured three days, eight weeks, and sixteen weeks after dual tenotomy with and without chemical paralysis via botulinum toxin A (BTX). Muscle mass and physiological cross-sectional area increased over time in the age-matched control animals, decreased over time in the tenotomy+BTX group, and remained nearly the same in the tenotomy-alone group. Tenotomy+BTX led to increased extracellular collagen in the muscle. Changes in scapular bone morphology were observed in both experimental groups, consistent with reductions in load transmission across the joint. These data suggest that tenotomy alone interferes with normal age-related muscle growth. The addition of chemical paralysis yielded profound structural changes to the muscle and bone, potentially leading to impaired muscle function, increased muscle stiffness, and decreased bone strength. Structural musculoskeletal changes occur after tendon injury, and these changes are severely exacerbated with the addition of neuromuscular compromise.

    Recurrent nerve paralysis (RP) is one of the most frequent complications of thyroid surgery. It reduces vocal fold mobility. Nasal endoscopy, a mini-invasive procedure, is the conventional way to detect RP. We suggest a new approach based on laryngeal ultrasound and a specific data analysis was designed to help with the automated detection of RP. Ten subjects were enrolled for this feasibility study: four controls, three patients with RP and three patients without RP according to nasal endoscopy. The ultrasound protocol was based on a ten seconds B-mode acquisition in a coronal plane during normal breathing. Image processing included three steps: 1) automated detection of two consecutive closing and opening images, corresponding to extreme positions of vocal folds in the sequence of B-mode images, using principal component analysis of the image sequence; 2) positioning of three landmarks and robust tracking of these points using a multi-pyramidal refined optical flow approach; 3) estimation of quantitative parameters indicating left and right fractions of mobility, and motion symmetry. Results provided by automated image processing were compared to those obtained by an expert. Detection of extreme images was accurate; tracking of landmarks was reliable in 80% of cases. Motion symmetry indices showed similar values for controls and patients without RP. Fraction of mobility was reduced in cases of RP. Thus, our CAD system helped in the detection of RP. Laryngeal ultrasound combined with appropriate image processing helped in the diagnosis of recurrent nerve paralysis and could be proposed as a first-line method.

    Patients use several online resources to learn about vocal cord paralysis (VCP). The objective of this study was to assess the readability and understandability of online VCP patient education materials (PEMs), with readability assessments and the Patient Education Materials Evaluation Tool (PEMAT), respectively. The relationship between readability and understandability was then analyzed. Descriptive and correlational design. Online PEMs were identified by performing a Google search with the term "vocal cord paralysis." After scientific webpages, news articles, and information for medical professionals were excluded, 29 articles from the first 50 search results were considered. Readability analysis was performed with 6 formulas. Four individuals with different educational backgrounds conducted understandability analysis with the PEMAT. Fleiss's Kappa interrater reliability analysis determined consistency among raters. Correlation between readability and understandability was determined with Pearson's correlation test. The reading level of the reviewed articles ranged from grades 9 to 17. Understandability ranged from 29% to 82%. Correlation analysis demonstrated a strong negative correlation between materials' readability and understandability (r = -0.462, P Online PEMs pertaining to VCP are written above the recommended reading levels. Overall, materials written at lower grade levels are more understandable. However, articles of identical grade levels had varying levels of understandability. The PEMAT may provide a more critical evaluation of the quality of a PEM when compared with readability formulas. Both readability and understandability should be used to evaluate PEMs. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

  9. Characterisation of Structural Proteins from Chronic Bee Paralysis Virus (CBPV Using Mass Spectrometry

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Chronic bee paralysis virus (CBPV is the etiological agent of chronic paralysis, an infectious and contagious disease in adult honeybees. CBPV is a positive single-stranded RNA virus which contains two major viral RNA fragments. RNA 1 (3674 nt and RNA 2 (2305 nt encode three and four putative open reading frames (ORFs, respectively. RNA 1 is thought to encode the viral RNA-dependent RNA polymerase (RdRp since the amino acid sequence derived from ORF 3 shares similarities with the RdRP of families Nodaviridae and Tombusviridae. The genomic organization of CBPV and in silico analyses have suggested that RNA 1 encodes non-structural proteins, while RNA 2 encodes structural proteins, which are probably encoded by ORFs 2 and 3. In this study, purified CBPV particles were used to characterize virion proteins by mass spectrometry. Several polypeptides corresponding to proteins encoded by ORF 2 and 3 on RNA 2 were detected. Their role in the formation of the viral capsid is discussed.

    Our research group has described both morphological and electrophysiological changes in motor cortex pyramidal neurons associated with contralateral facial nerve injury in rats. However, little is known about those neural changes, which occur together with changes in surrounding glial cells. To characterize the effect of the unilateral facial nerve injury on microglial proliferation and activation in the primary motor cortex. We performed immunohistochemical experiments in order to detect microglial cells in brain tissue of rats with unilateral facial nerve lesion sacrificed at different times after the injury. We caused two types of lesions: reversible (by crushing, which allows functional recovery), and irreversible (by section, which produces permanent paralysis). We compared the brain tissues of control animals (without surgical intervention) and sham-operated animals with animals with lesions sacrificed at 1, 3, 7, 21 or 35 days after the injury. In primary motor cortex, the microglial cells of irreversibly injured animals showed proliferation and activation between three and seven days post-lesion. The proliferation of microglial cells in reversibly injured animals was significant only three days after the lesion. Facial nerve injury causes changes in microglial cells in the primary motor cortex. These modifications could be involved in the generation of morphological and electrophysiological changes previously described in the pyramidal neurons of primary motor cortex that command facial movements.

    IgG and IgA immunocompetence of children with wild poliovirus poliomyelitis and non-polio acute flaccid paralysis. 932 cases of acute flaccid paralysis, reported in 2008-2009, were tested for presence of polio and non-polio enteroviruses according to the WHO standards. Serum IgA and IgG levels were determined by sandwich ELISA. Mean (SD) IgA levels [0.87 (0.62)g/L; n=28] of virologically confirmed poliomyelitis cases were lower than those of virus negative [1.21 (0.83)g/L; n=612] and non-polio Enterovirus positive [1.22 (0.79)g/L; n=240] cases of acute flaccid paralysis. No significant difference was observed in the concentration of IgG among these groups. IgA plays an important role in protection against poliomyelitis.

    Full Text Available Chronic bee paralysis virus (CBPV infection causes chronic paralysis and loss of workers in honey bee colonies around the world. Although CBPV shows a worldwide distribution, it had not been molecularly detected in Japan. Our investigation of Apis mellifera and Apis cerana japonica colonies with RT-PCR has revealed CBPV infection in A. mellifera but not A. c. japonica colonies in Japan. The prevalence of CBPV is low compared with that of other viruses: deformed wing virus (DWV, black queen cell virus (BQCV, Israel acute paralysis virus (IAPV, and sac brood virus (SBV, previously reported in Japan. Because of its low prevalence (5.6% in A. mellifera colonies, the incidence of colony losses by CBPV infection must be sporadic in Japan. The presence of the (− strand RNA in dying workers suggests that CBPV infection and replication may contribute to their symptoms. Phylogenetic analysis demonstrates a geographic separation of Japanese isolates from European, Uruguayan, and mainland US isolates. The lack of major exchange of honey bees between Europe/mainland US and Japan for the recent 26 years (1985–2010 may have resulted in the geographic separation of Japanese CBPV isolates.

  14. A neonatal mouse spinal cord injury model for assessing post-injury adaptive plasticity and human stem cell integration.

    Directory of Open Access Journals (Sweden)

    Jean-Luc Boulland

    Full Text Available Despite limited regeneration capacity, partial injuries to the adult mammalian spinal cord can elicit variable degrees of functional recovery, mediated at least in part by reorganization of neuronal circuitry. Underlying mechanisms are believed to include synaptic plasticity and collateral sprouting of spared axons. Because plasticity is higher in young animals, we developed a spinal cord compression (SCC injury model in the neonatal mouse to gain insight into the potential for reorganization during early life. The model provides a platform for high-throughput assessment of functional synaptic connectivity that is also suitable for testing the functional integration of human stem and progenitor cell-derived neurons being considered for clinical cell replacement strategies. SCC was generated at T9-T11 and functional recovery was assessed using an integrated approach including video kinematics, histology, tract tracing, electrophysiology, and high-throughput optical recording of descending inputs to identified spinal neurons. Dramatic degeneration of axons and synaptic contacts was evident within 24 hours of SCC, and loss of neurons in the injured segment was evident for at least a month thereafter. Initial hindlimb paralysis was paralleled by a loss of descending inputs to lumbar motoneurons. Within 4 days of SCC and progressively thereafter, hindlimb motility began to be restored and descending inputs reappeared, but with examples of atypical synaptic connections indicating a reorganization of circuitry. One to two weeks after SCC, hindlimb motility approached sham control levels, and weight-bearing locomotion was virtually indistinguishable in SCC and sham control mice. Genetically labeled human fetal neural progenitor cells injected into the injured spinal cord survived for at least a month, integrated into the host tissue and began to differentiate morphologically. This integrative neonatal mouse model provides opportunities to explore early

    A 26-year-old patient is described with a unique migraine aura. She described an 8-year history of episodes occurring 1 to 2 times yearly of exploding head syndrome followed by sleep paralysis followed by a migraine headache. She also had identical headaches without aura about once per week. Both aura symptoms, which may occur in the brainstem, resulted in activation of the trigeminovascular system through an unknown mechanism.

    2008-01-01

    BACKGROUND:Brain injury patients often exhibit learning and memory functional deficits.Long-term potentiation(LTP)is a representative index for studying learning and memory cellular models; the LTP index correlates to neural plasticity. OBJECTIVE:This study was designed to investigate correlations of learning and memory functions to LTP in brain injury patients,and to summarize the research advancements in mechanisms underlying brain functional improvements after rehabilitation intervention. RETRIEVAL STRATEGY:Using the terms "brain injuries,rehabilitation,learning and memory,long-term potentiation",manuscripts that were published from 2000-2007 were retrieved from the PubMed database.At the same time,manuscripts published from 2000-2007 were also retrieved from the Database of Chinese Scientific and Technical Periodicals with the same terms in the Chinese language.A total of 64 manuscripts were obtained and primarily screened.Inclusion criteria:studies on learning and memory,as well as LTP in brain injury patients,and studies focused on the effects of rehabilitation intervention on the two indices; studies that were recently published or in high-impact journals.Exclusion criteria:repetitive studies.LITERATURE EVALUATION:The included manuscripts primarily focused on correlations between learning and memory and LTP,the effects of brain injury on learning and memory,as well as LTP,and the effects of rehabilitation intervention on learning and memory after brain injury.The included 39 manuscripts were clinical,basic experimental,or review studies. DATA SYNTHESIS:Learning and memory closely correlates to LTP.The neurobiological basis of learning and memory is central nervous system plasticity,which involves neural networks,neural circuits,and synaptic connections,in particular,synaptic plasticity.LTP is considered to be an ideal model for studying synaptic plasticity,and it is also a classic model for studying neural plasticity of learning and memory.Brain injury

    The aim of this study was to examine changes in passive length and stiffness of the gastrocnemius muscle-tendon unit in people after spinal cord injury. In a prospective longitudinal study, eight wheelchair-dependent participants with severe paralysis were assessed 3 and 12 mos after spinal cord injury. Passive torque-angle data were obtained as the ankle was slowly rotated through range at six knee angles. Differences in passive ankle torque-angle data recorded at different knee angles were used to derive passive length-tension curves of the gastrocnemius muscle-tendon unit. Ultrasound imaging was used to determine fascicle and tendon contributions to the muscle-tendon unit length-tension curves. The participants had ankle contractures (mean [SD] maximum passive ankle dorsiflexion angle, 88 [9] degrees) 3 mos after spinal cord injury. Ankle range did not worsen significantly during the subsequent 9 mos (mean change, -5 degrees; 95% confidence interval, -16 to 6 degrees). There were no changes in the mean slack length or the stiffness of the gastrocnemius muscle-tendon unit or in the slack lengths of the fascicles or the tendon between 3 and 12 mos after spinal cord injury. There were no consistent patterns of the change in slack length or stiffness with the changes in ankle range in the data from the individual participants. This study, the first longitudinal study of muscle length and stiffness after spinal cord injury, showed that the length and the stiffness of the gastrocnemius did not change substantially between 3 and 12 mos after injury.

    A 62-year-old man with well-controlled diabetes mellitus developed numbness of the bilateral feet and hands, followed by subacutely progressive weakness and amyotrophy of extremities. He became bed-ridden state, and dyspnea also appeared, so he was referred to our hospital. Physical examination revealed a lean man, with dark-reddish skin pigmentation, crabbed fingers, bilateral pretibial pitting edema, and bristles in extremities. Thoracoabdominal paradoxical respiration was observed and pulmonary vesicular sounds was decreased markedly in the both lungs. Laboratory data revealed hypoproteinemia, abnormalities of endocrine system, but M-protein was not detected. Serum vascular endothelial growth factor level was quite high. Chest radiography revealed elevation of the bilateral diaphragm, the % vital capacity (%VC) was 24%, and arterial blood gas analysis showed marked hypoxia with hypercapnia. These findings suggested that his respiratory failure was induced by bilateral diaphragmatic paralysis caused by bilateral phrenic nerve palsy due to Crow-Fukase syndrome. He became somnolent because of hypercapnic narcosis, so non-invasive positive pressure ventilation (NIPPV) was started. We treated him with intravenous immunoglobulin and oral corticosteroids therapies, and after these therapies, his symptoms were remarkably recovered and NIPPV became unnecessary soon. The most frequent causes of respiratory failure in Crow-Fukase syndrome are pleural effusion and pulmonary hypertension, and only two cases of this syndrome with respiratory failure caused by bilateral diaphragmatic paralysis were reported until now. When the patients with Crow-Fukase syndrome complain of dyspnea, we should take the diaphragmatic paralysis into consideration, which may be improved by appropriate therapies.

    Full Text Available BackgroundThis paper discusses the various methods and the materialsfor the fabrication of active artificial facial muscles. Theprimary use for these will be the reanimation of paralysedor atrophied muscles in sufferers of non-recoverableunilateral facial paralysis.MethodThe prosthetic solution described in this paper is based onsensing muscle motion of the contralateral healthy musclesand replicating that motion across a patient’s paralysed sideof the face, via solid state and thin film actuators. Thedevelopment of this facial prosthetic device focused onrecreating a varying intensity smile, with emphasis ontiming, displacement and the appearance of the wrinklesand folds that commonly appear around the nose and eyesduring the expression.An animatronic face was constructed with actuations beingmade to a silicone representation musculature, usingmultiple shape-memory alloy cascades. Alongside theartificial muscle physical prototype, a facial expressionrecognition software system was constructed. This formsthe basis of an automated calibration and reconfigurationsystem for the artificial muscles following implantation, soas to suit the implantee’s unique physiognomy.ResultsAn animatronic model face with silicone musculature wasdesigned and built to evaluate the performance of ShapeMemory Alloy artificial muscles, their power controlcircuitry and software control systems. A dual facial motionsensing system was designed to allow real time control overmodel – a piezoresistive flex sensor to measure physicalmotion, and a computer vision system to evaluate real toartificial muscle performance.Analysis of various facial expressions in real subjects wasmade, which give useful data upon which to base thesystems parameter limits.ConclusionThe system performed well, and the various strengths andshortcomings of the materials and methods are reviewedand considered for the next research phase, when newpolymer based artificial muscles are constructed

    This study aims to discuss clinical characteristics, image manifestation and treatment methods of temporal bone lesions with facial paralysis as the main manifestation for deepening the understanding of such type of lesions and reducing erroneous and missed diagnosis. The clinical data of 16 patients with temporal bone lesions and facial paralysis as main manifestation, who were diagnosed and treated from 2009 to 2016, were retrospectively analyzed. Among these patients, six patients had congenital petrous bone cholesteatoma (PBC), nine patients had facial nerve schwannoma, and one patient had facial nerve hemangioma. All the patients had an experience of long-term erroneous diagnosis. The lesions were completely excised by surgery. PBC and primary facial nerve tumors were pathologically confirmed. Facial-hypoglossal nerve anastomosis was performed on two patients. HB grade VI was recovered to HB grade V in one patient. The anastomosis failed due to severe facial nerve fibrosis in one patient. Hence, HB remained at grade VI. Postoperative recovery was good for all patients. No lesion recurrence was observed after 1-6 years of follow-up. For the patients with progressive or complete facial paralysis, imaging examination should be perfected in a timely manner. Furthermore, PBC, primary facial nerve tumors and other temporal bone space-occupying lesions should be eliminated. Lesions should be timely detected and proper intervention should be conducted, in order to reduce operation difficulty and complications, and increase the opportunity of facial nerve function reconstruction.

    Full Text Available Neuralgic amyotrophy, also known as brachial neuritis, is a well described clinical entity. Diaphragmatic dysfunction, as a result of phrenic nerve root involvement (cervical roots 3 to 5, is an uncommon, but increasingly recognized association. The case of a previously healthy 61-year-old woman who, after a prodrome of neck and shoulder discomfort, presented with severe orthopnea is described. Pulmonary function and electrophysiological studies led to a diagnosis of bilateral diaphragmatic paralysis. The patient's clinical course and the exclusion of other nerve entrapment syndromes and neurological disorders strongly favoured the diagnosis of neuralgic amyotrophy.

    2017-01-01

    Full Text Available Medialization thyroplasty or injection laryngoplasty for unilateral vocal fold paralysis cannot restore mobility of the vocal fold. Recent studies have shown that transplantation of mesenchymal stem cells is effective in the repair of nerve injuries. This study investigated whether adipose-derived stem cell transplantation could repair recurrent laryngeal nerve injury. Rat models of recurrent laryngeal nerve injury were established by crushing with micro forceps. Adipose-derived mesenchymal stem cells (ADSCs; 8 × 105 or differentiated Schwann-like adipose-derived mesenchymal stem cells (dADSCs; 8 × 105 or extracellular matrix were injected at the site of injury. At 2, 4 and 6 weeks post-surgery, a higher density of myelinated nerve fiber, thicker myelin sheath, improved vocal fold movement, better recovery of nerve conduction capacity and reduced thyroarytenoid muscle atrophy were found in ADSCs and dADSCs groups compared with the extracellular matrix group. The effects were more pronounced in the ADSCs group than in the dADSCs group. These experimental results indicated that ADSCs transplantation could be an early interventional strategy to promote regeneration after recurrent laryngeal nerve injury.

    Bell palsy is largely a diagnosis of exclusion, but certain features in the history and physical examination help distinguish it from facial paralysis due to other conditions: eg, abrupt onset with complete, unilateral facial weakness at 24 to 72 hours, and, on the affected side, numbness or pain around the ear, a reduction in taste, and hypersensitivity to sounds. Corticosteroids and antivirals given within 10 days of onset have been shown to help. But Bell palsy resolves spontaneously without treatment in most patients within 6 months.

    To investigate the clinical and electrophysiological features of facial nerve paralysis (FNP) due to benign temporal bone masses (TBMs) and elucidate its differences as compared with Bell's palsy. FNP assessed by the House-Brackmann (HB) grading system and by electroneurography (ENoG) were compared retrospectively. We reviewed 914 patient records and identified 31 patients with FNP due to benign TBMs. Moderate FNP (HB Grades II-IV) was dominant for facial nerve schwannoma (FNS) (n=15), whereas severe FNP (Grades V and VI) was dominant for cholesteatomas (n=8) and hemangiomas (n=3). The average ENoG value was 19.8% for FNS, 15.6% for cholesteatoma, and 0% for hemangioma. Analysis of the correlation between HB grade and ENoG value for FNP due to TBMs and Bell's palsy revealed that given the same ENoG value, the corresponding HB grade was better for FNS, followed by cholesteatoma, and worst in Bell's palsy. Facial nerve damage caused by benign TBMs could depend on the underlying pathology. Facial movement and ENoG values did not correlate when comparing TBMs and Bell's palsy. When the HB grade is found to be unexpectedly better than the ENoG value, TBMs should be included in the differential diagnosis. Copyright © 2017 Elsevier B.V. All rights reserved.

    Approximately 6 million people in the United States are currently living with paralysis in which 23% of the cases are related to spinal cord injury (SCI). Miniaturized closed-loop neural interfaces have the potential for restoring function and mobility lost to debilitating neural injuries such as SCI by leveraging recent advancements in bioelectronics and a better understanding of the processes that underlie functional and anatomical reorganization in an injured nervous system. This paper describes our current progress toward developing a miniaturized brain-machine-spinal cord interface (BMSI) that converts in real time the neural command signals recorded from the cortical motor regions to electrical stimuli delivered to the spinal cord below the injury level. Using a combination of custom integrated circuit (IC) technology for corticospinal interfacing and field-programmable gate array (FPGA)-based technology for embedded signal processing, we demonstrate proof-of-concept of distinct muscle pattern activation via intraspinal microstimulation (ISMS) controlled in real time by intracortical neural spikes in an anesthetized laboratory rat.

    Full Text Available Hemi-sectioned spinal cord injury (hSCI can lead to spastic paralysis on the injured side, as well as flaccid paralysis on the contralateral side, which can negatively affect a patient’s daily life. Stem-cell therapy may offer an effective treatment option for individuals with hSCI. To examine the role of bone marrow mesenchymal stem cells (BMSCs transplantation on hSCI and explore related mechanisms in the tree shrews, here, we created a model of hSCI by inducing injury at the tenth thoracic vertebra (T10. Hoechst 33342-labeled BMSCs derived from adult tree shrews were isolated, cultured, and implanted into the spinal cord around the injury site at 9 days after injury. The isolated BMSCs were able to survive, proliferate and release a variety of neurotrophic factors (NTFs both in vitro and in vivo. At 28 days after injury, compared with the sham group, the hSCI group displayed scar formation and dramatic elevations in the mean interleukin 1 beta (IL-1β density and cell apoptosis level, whereas the expression of signal transducer and activator of transcription 3 (STAT3 and ciliary neurotrophic factor (CNTF mRNA was reduced. Following BMSC transplantation, motoneurons extent of shrinkage were reduced and the animals’ Basso, Beattie, and Bresnahan (BBB locomotion scale scores were significantly higher at 21 and 28 days after injury when compared with the injured group. Moreover, the hSCI-induced elevations in scar formation, IL-1β, and cell apoptosis were reduced by BMSC transplantation to levels that were close to those of the sham group. Corresponding elevations in the expression of STAT3 and CNTF mRNA were observed in the hSCI + BMSCs group, and the levels were not significantly different from those observed in the sham group. Together, our results support that grafted BMSCs can significantly improve locomotor function in tree shrews subjected to hSCI and that this improvement is associated with the upregulation of CNTF and STAT3

    To evaluate the effect of agmatine sulphate on facial nerve regeneration after facial nerve injury using electron and light microscopy. The study was performed on 30 male Wistar albino rats split into: a control group, a sham-treated group, a study control group, an anastomosis group, and an anastomosis plus agmatine sulphate treatment group. The mandibular branch of the facial nerve was dissected, and a piece was removed for histological and electron microscopic examination. Regeneration was better in the anastomosis group than in the study control group. However, the best regeneration findings were seen in the agmatine sulphate treatment group. There was a significant difference between the agmatine group and the others in terms of median axon numbers (p Agmatine sulphate treatment with anastomosis in traumatic facial paralysis may enhance nerve regeneration.

    The risk of producing bilateral laryngeal paralysis (BLP) in total thyroidectomy (TT) is low, but it is a concern for the surgeon and a serious safety incident that may compromise the airway, require reintubation or tracheostomy and cause serious sequelae or death. Neuromonitoring (NM), as an early diagnostic tool for the existence of injury to the recurrent laryngeal nerve (RLN), has not been shown to have reduced the risk, even though published series show lower incidences. Our objective was to estimate the risk of bilateral RLN paralysis with and without NM TT by systematic review and meta-analysis. We performed a systematic review of clinical trials, cohort studies and case series with total thyroidectomy without NM published in the period 2000-2014. A database search was performed using PubMed, Scopus (EMBASE) and the Cochrane Library. Heterogeneity between studies was explored and weighted risks grouped according to random effects models were estimated. We selected 40 articles and estimates of risk were identified in 54 case series (without NM, 25; with NM, 29) with 30,922 patients. The prevalence of BLP in the series with NM was lower compared to that without NM (2.43‰, [1.55 to 3.5‰] versus 5.18‰ [2.53 to 8.7‰]). This difference is equivalent to an absolute risk reduction of 2.75‰ with a number needed to treat of 364.13. The NM group was more homogeneous (I2=7.52%) than those without NM (I2=79.32%). The observed differences in the subgroup analysis were very imprecise because the number of observed paralysis was very low. The risk of bilateral paralysis is lower in studies with neuromonitoring.

    Car surfing, in which participants stand on top of a moving vehicle as though it were a surfboard, has been reported as a cause of traumatic injury in only 5 cases in the literature. Over the last 8 years, however, the authors have treated 26 children, primarily adolescents, for injuries resulting from car surfing. This report describes the injuries and outcomes of this potentially underreported mechanism of injury. Medical records of 26 patients treated for car surfing injuries between 1991 and 1999 were reviewed. Demographics, hospital course, and type and severity of injuries were analyzed. Eighteen boys (69%) and 8 girls (31%) with an average age of 15.7+/-3.4 years (range, 6 to 22) have presented with injuries related to car surfing. All patients had fallen from the hood, roof, or trunk of a moving motor vehicle, the majority falling from the hood (n = 13; 50%). Injury severity was evaluated using the Injury Severity Scores (ISS; 12.4+/-6.5), Revised Trauma Score (RTS; 7.5+/- 1.1) and Glasgow Coma Score (GCS; 13.5+/-3.2). Injury severity was equivalent between boys and girls (P>.05). Central nervous system injuries predominated, with closed head injuries occurring in 22 (85%) and loss of consciousness in 10 (39%). Skull fractures occurred in 11 (42%) and intracranial bleeding in 9 (35%). Long-term cognitive rehabilitation was necessary in 22 (85%) patients. Three patients (12%) had spinal column fractures, with 2 (8%) suffering permanent paralysis. Two extremity (8%) and 3 (11.7%) pelvic fractures occurred. Most patients (73%) suffered significant skin and soft tissue injuries. Two patients (8%) presented with solid visceral injuries, and 1 child died. Car surfing is an extremely high-risk behavior in children and adolescents that leads to significant morbidity, long-term disability, and is potentially fatal. The incidence of car surfing may be greater than has been reported previously; therefore, prevention programs aimed at discouraging this high

    2011-01-01

    To review the potential adverse effects of thyroid hormone-based nutraceuticals and describe a case of thyrotoxic periodic paralysis (TPP) after abuse of a dietary supplement containing 3,5,3'-triiodothyroacetic acid (tiratricol). We review the literature on potential dangers and therapeutic misadventures of thyroid hormone-based nutraceuticals and present the clinical, laboratory, and radiologic data of a bodybuilder in whom hypokalemic TPP developed after use of "Triax Metabolic Accelerator". A 23-year-old white man developed lower extremity paralysis, diaphoresis, and palpitations in the setting of low serum potassium levels. Laboratory results showed suppressed thyroid-stimulating hormone, low levels of free and total thyroxine, low total triiodothyronine level, and very low 24-hour radioiodine uptake. The patient ultimately admitted to taking a supplement containing tiratricol for approximately 2 months, and hypokalemic TPP was diagnosed. He was treated with potassium supplementation and a β-adrenergic blocking agent, which completely resolved his symptoms. Results of thyroid function tests normalized or approached normal 1 week after hospitalization, and future use of dietary supplements was strongly discouraged. Despite 2 warnings by the US Food and Drug Administration, products containing tiratricol are still available for sale on the Internet. This report illustrates both an unusual adverse effect of a nutraceutical containing tiratricol and the importance of educating our patients about the risks versus benefits of using these widely available but loosely regulated products.

    Purpose: To evaluate the value of three-dimensional (3D) constructive interference in steady-state (CISS) magnetic resonance (MR) imaging with multi-planar reconstruction (MPR) in displaying the relationship between the oculomotor nerve and its adjacent structures for patients with oculomotor paralysis. Materials and methods: 17 consecutive patients with oculomotor paralysis were examined with 3D-CISS and conventional spin-echo (SE) sequences on a 1.5-Tesla MR system. Original transverse and MPR images were used for image interpretation. The features of the oculomotor nerve and its adjacent structures were identified. The diagnosis was surgically confirmed in all patients. Results: Through 3D-CISS with MPR images, obvious relationship of the oculomotor nerve and its adjacent structures was demonstrated on 17 patients. Of those oculomotor nerves, 15 were compressed by the arteries (n = 15), one by the craniopharyngioma (n = 1), and another one by the neurofibroma (n = 1). Conclusion: 3D-CISS MR imaging with MPR provides an excellent way to characterize the relationship between the nerve and its adjacent structures in the cisternal segment of the oculomotor nerve in the patients with oculomotor paralysis. Moreover, this method shows anatomical details for imaging diagnosis and surgical procedure.

    Thyrotoxic periodic paralysis (TPP) is an uncommon complication of Graves' disease, characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. Graves' encephalopathy is an extremely rare form of encephalopathy associated with autoimmune thyroid disease (EAATD), characterized by neuropsychiatric symptoms, increased antithyroid antibodies and cerebrospinal fluid protein concentration, nonspecific electroencephalogram abnormalities, and cortico-responsiveness. Coexistence of both these complications in the same patient has not been reported before. We herein present a 48-year-old white male patient with TPP and encephalopathy as initial presentations of Graves' disease. Flaccid tetraparesis was reversed a few hours after potassium level correction and the patient did not suffer any relapse with the successful pharmaceutical management of the thyroid function. One month later, the patient presented with dizziness and behavioral symptoms, such as inappropriate laughter and anger. Brain magnetic resonance imaging revealed meningeal enhancement and cerebrospinal fluid analysis showed a mild protein increase, with a blood-brain barrier disruption. With the suspicion of EAATD, the patient was treated with high doses of corticosteroids and improved dramatically. To our knowledge this is the first reported coexistence of potentially treatable TPP and EAATD as initial neurological manifestations of Graves' disease, thereby underscoring the necessity of suspicion of possible underlying Graves' disease in patients with acute paralysis and encephalopathy of unclear origin.

    This trial was designed to evaluate the efficacy of EPOREC 1 500 magnets as an adjuvant to rehabilitation following peripheral facial paralysis. Magnetotherapy is used in many other specialties, and in particular in rheumatology. The properties of repulsion between identical poles were used to decrease the effect of sequelae in the form of contractures on the facial muscles. There were two groups of 20 patients: one group with physiotherapy only and the other with standard rehabilitation together with the use of magnets. These 40 patients had facial paralysis of various origins (trauma, excision of acoustic neuroma, Bell's palsy etc). Obviously all patients had an intact nerve. It was at the time of the development of contractures that magnets could be used in terms of evaluation of their efficacy of action on syncinesiae, contractures and spasticity. Magnets were worn at night for a mean period of six months and results were assessed in terms of disappearance of eye-mouth syncinesiae, and in terms of normality of facial tone. Improvement and total recovery without sequelae were obtained far more frequently in the group which wore magnets, encouraging us to continue along these lines.

    Assessment of facial paralysis (FP) and quantitative grading of facial asymmetry are essential in order to quantify the extent of the condition as well as to follow its improvement or progression. As such, there is a need for an accurate quantitative grading system that is easy to use, inexpensive and has minimal inter-observer variability. A comprehensive automated system to quantify and grade FP is the main objective of this work. An initial prototype has been presented by the authors. The present research aims to enhance the accuracy and robustness of one of this system's modules: the resting symmetry module. This is achieved by including several modifications to the computation method of the symmetry index (SI) for the eyebrows, eyes and mouth. These modifications are the gamma correction technique, the area of the eyes, and the slope of the mouth. The system was tested on normal subjects and showed promising results. The mean SI of the eyebrows decreased slightly from 98.42% to 98.04% using the modified method while the mean SI for the eyes and mouth increased from 96.93% to 99.63% and from 95.6% to 98.11% respectively while using the modified method. The system is easy to use, inexpensive, automated and fast, has no inter-observer variability and is thus well suited for clinical use.

    Full Text Available Hyperkalemia can present with a spectrum of clinical manifestations with progressive EKG changes and life-threatening arrhythmias. Although no formal guidelines exist as to when to initiate treatment for hyperkalemia, it is generally recommended in clinically symptomatic patients with or without EKG changes. Timely diagnosis and reversal can relieve symptoms and prevent life-threatening arrhythmias. We review the EKG changes associated with hyperkalemia and management principles along with an example of a case of severe hyperkalemia resulting in arrhythmia and flaccid paralysis.

    Thyrotoxic periodic paralysis (TPP) is rare in non-Orientals, and sporadic case reports were reported world-wide. Eight cases were reported in Arabs, including 3 Saudis. We present an additional case of TPP in a 38-year-old Saudi man, and review the literature on TPP in Arabs. Our patient presented with complete flaccid quadriplegia, 5 weeks after he was diagnosed with Graves' disease that was treated with carbimazole and propranolol. He was hyperthyroid, and his potassium was extremely low (1.5 mmol/L). During initial evaluation in the emergency room, he developed transient asystole manifested by syncope. He was resuscitated and his hypokalemia was corrected, and he had a full recovery. This case emphasizes the notion that TPP can occur in patients of any ethnic background. The development of serious cardiac complications in our patient underscores the importance of early and correct diagnosis of this potentially life-threatening complication of hyperthyroidism.

    A case of chronic meningoencephalomyelitis in a 48-year-old housewife is presented. The onset was characterized by spastic paralysis of the lower extremities. The course was progressive with repeated remissions and exacerbations, and the patient died approximately 7 years after the onset of disease. Laboratory tests showed slightly increased cell count in the spinal fluid, accelerated sedimentation rate, positive CRP and RA, and increased ASLO and gamma globulin levels. Neuropathologic examination revealed such changes as perivascular cellular infiltration, glial nodules, poorly demarcated demyelination, and recent necrosis in the spinal cord and basal ganglia. Only mild inflammatory findings were noted in the telencephalon and brain stem. The clinicopathologic findings in this case supported a diagnosis of chronic meningoencepalomyelitis which could not be classified as any known type of encephalomyelitis. (auth)

The evaluation was done by reviewing the Hospitals' Record (Hospital Based Survey. The objective of the survey was to estimate the under reported of routine reporting system, which the data of the survey used as a gold standard. The results showed that due to incomplete of the records in several hospitals, some of AFP cases might be could not be covered. However the under reported of the routine surveillance system was more than 50%. It seems that the strengthening of supervision was still needed to increase coverage of the routine surveillance system.   Keywords: hospitals; medical record; acute flocid paralysis

    Full Text Available Non-polio enteroviruses (NPEVs are among the most common viruses infecting humans worldwide. Most of these infections are asymptomatic but few can lead to systemic and neurological disorders like Acute Flaccid Paralysis (AFP. Acute Flaccid Paralysis is a clinical syndrome and NPEVs have been isolated frequently from the patients suffering from AFP but little is known about their causal relationship. The objective of this study was to identify and characterize the NPEV serotypes recovered from 184 stool samples collected from AFP patients in Federally Administered Tribal Areas (FATA in north-west of Pakistan. Overall, 44 (95.6 % isolates were successfully typed through microneutralization assay as a member of enterovirus B species including echovirus (E-2, E-3, E-4, E-6, E-7, E-11, E-13, E-14, E-21 and E-29 while two isolates (PAK NIH SP6545B and PAK NIH SP1202B remained untypeable. The VP1 and capsid regions analysis characterized these viruses as EV-B93 and EV-B106. Phylogenetic analysis confirmed that PAK NIH isolates had high genetic diversity and represent distinct genotypes circulating in the country. Our findings highlight the role of NPEVs in AFP cases to be thoroughly investigated especially in high disease risk areas, with limited surveillance activities and health resources.

    Full Text Available A paralisia facial causada pelo colesteatoma é pouco freqüente. As porções do nervo mais acometidas são a timpânica e a região do 2º joelho. Nos casos de disseminação da lesão colesteatomatosa para o epitímpano anterior, o gânglio geniculado é o segmento do nervo facial mais sujeito à injúria. A etiopatogenia pode estar ligada à compressão do nervo pelo colesteatoma seguida de diminuição do seu suprimento vascular como também pela possível ação de substâncias neurotóxicas produzidas pela matriz do tumor ou pelas bactérias nele contidas. OBJETIVO: Avaliar a incidência, as características clínicas e o tratamento da paralisia facial decorrente da lesão colesteatomatosa. FORMA DE ESTUDO: Clínico retrospectivo. MATERIAL E MÉTODO: Estudo retrospectivo envolvendo dez casos de paralisia facial por colesteatoma selecionados através de levantamento de 206 descompressões do nervo facial com diferentes etiologias, realizadas na UNIFESP-EPM nos últimos dez anos. RESULTADOS: A incidência de paralisia facial por colesteatoma neste estudo foi de 4,85%,com predominância do sexo feminino (60%. A idade média dos pacientes foi de 39 anos. A duração e o grau da paralisia (inicial juntamente com a extensão da lesão foram importantes em relação à recuperação funcional do nervo facial. CONCLUSÃO: O tratamento cirúrgico precoce é fundamental para que ocorra um resultado funcional mais adequado. Nos casos de ruptura ou intensa fibrose do tecido nervoso, o enxerto de nervo (auricular magno/sural e/ou a anastomose hipoglosso-facial podem ser sugeridas.Facial paralysis caused by cholesteatoma is uncommon. The portions most frequently involved are horizontal (tympanic and second genu segments. When cholesteatomas extend over the anterior epitympanic space, the facial nerve is placed in jeopardy in the region of the geniculate ganglion. The aetiology can be related to compression of the nerve followed by impairment of its

    Translation of therapeutic interventions for spinal cord injury (SCI) from laboratory to clinic has been historically challenging, highlighting the need for robust models of injury that more closely mirror the human condition. The high prevalence of acute, naturally occurring SCI in pet dogs provides a unique opportunity to evaluate expeditiously promising interventions in a population of animals that receive diagnoses and treatment clinically in a manner similar to persons with SCI, while adhering to National Institutes of Health guidelines for scientific rigor and transparent reporting. In addition, pet dogs with chronic paralysis are often maintained long-term by their owners, offering a similarly unique population for study of chronic SCI. Despite this, only a small number of studies have used the clinical dog model of SCI. The Canine Spinal Cord Injury Consortium (CANSORT-SCI) was recently established by a group of veterinarians and basic science researchers to promote the value of the canine clinical model of SCI. The CANSORT-SCI group held an inaugural meeting November 20 and 21, 2015 to evaluate opportunities and challenges to the use of pet dogs in SCI research. Key challenges identified included lack of familiarity with the model among nonveterinary scientists and questions about how and where in the translational process the canine clinical model would be most valuable. In light of these, we review the natural history, outcome, and available assessment tools associated with canine clinical SCI with emphasis on their relevance to human SCI and the translational process.

    Injection laryngoplasty (glottis augmentation) is the preferred method in surgical management of unilateral vocal fold paralysis (UVFP). Traditionally, these procedures are performed in the operating room. Nowadays, however, these procedures have moved into the office. To evaluate the voice quality after transoral injection laryngoplasty under local anaesthesia in patients with unilateral vocal fold paralysis. Fourteen subjects (5 women and 9 men) with unilateral vocal fold paresis (9 with right vocal fold paresis and 5 with left vocal fold paresis) were included in the study. The mean age of the group was 57.8 ±19.0 years (32-83 years). All of the injection laryngoplasties were performed transorally, under local anaesthesia. The injection material was calcium hydroxylapatite. Before and 1, 3 and 6 months after the procedure the following variables were evaluated: voice perception, videostroboscopy, acoustic analysis, aerodynamic evaluation, and the subjective rating of the voice quality by the patient. After injection laryngoplasty, complete glottal closure was achieved or there was a significant improvement in the glottal closure of each subject. We noted great improvement in the post-injection objective and subjective voice outcomes and patients reported improvement in the voice-related quality of life. The transoral approach for injection laryngoplasty under local anaesthesia is an effective and safe way to treat incomplete glottal closure in patients with UVFP. The transoral approach is an efficient alternative to other surgical techniques used for vocal fold injection.

    GD-DTPA-enhanced MR imaging was used to evaluate 11 patients with facial nerve paralysis (five acute idiopathic facial palsy (Bell palsy), three chronic recurrent facial palsy, one acute facial palsy after local radiation therapy, one chronic facial dyskinesia, and one facial neuroma). In eight of 11 patients, there was marked enhancement of the infratemporal facial nerve from the labyrinthine segment to the stylomastoid foramen. Two patients had additional contrast enhancement in the internal auditory canal segment. In one patient, enhancement persisted (but to a lesser degree) 8 weeks after symptoms had resolved. In one patient, no enhancement was seen 15 months after resolution of Bell palsy. The facial neuroma was seen as a focal nodular enhancement in the mastoid segment of the facial nerve

    Baseball and softball injuries can be a result of both acute and overuse injuries. Soft tissue injuries include contusions, abrasions, and lacerations. Return to play is allowed when risk of further injury is minimized. Common shoulder injuries include those to the rotator cuff, biceps tendon, and glenoid labrum. Elbow injuries are common in baseball and softball and include medial epicondylitis, ulnar collateral ligament injury, and osteochondritis dissecans. Typically conservative treatment with relative rest, medication, and a rehabilitation program will allow return to play. Surgical intervention may be needed for certain injuries or conservative treatment failure.

  19. Current Treatment Options for Bilateral Vocal Fold Paralysis: A State-of-the-Art Review

    Li, Yike; Garrett, Gaelyn; Zealear, David

    2017-01-01

    Vocal fold paralysis (VFP) refers to neurological causes of reduced or absent movement of one or both vocal folds. Bilateral VFP (BVFP) is characterized by inspiratory dyspnea due to narrowing of the airway at the glottic level with both vocal folds assuming a paramedian position. The primary objective of intervention for BVFP is to relieve patients’ dyspnea. Common clinical options for management include tracheostomy, arytenoidectomy and cordotomy. Other options that have been used with varying success include reinnervation techniques and botulinum toxin (Botox) injections into the vocal fold adductors. More recently, research has focused on neuromodulation, laryngeal pacing, gene therapy, and stem cell therapy. These newer approaches have the potential advantage of avoiding damage to the voicing mechanism of the larynx with an added goal of restoring some physiologic movement of the affected vocal folds. However, clinical data are scarce for these new treatment options (i.e., reinnervation and pacing), so more investigative work is needed. These areas of research are expected to provide dramatic improvements in the treatment of BVFP. PMID:28669149

    The management of the facial nerve in tumorous temporal lesions is particularly challenging due to its complex anatomic location and potential postoperative complications, including permanent facial paralysis. The most important concern regarding surgical treatment of a tumorous temporal lesion is the inevitable facial paralysis caused by nerve injury during the tumor removal, especially in patients with minimal to no preoperative facial nerve dysfunction. We describe successful four cases in which various surgical techniques were developed for the preservation of the facial nerve in treatment of intratemporal tumorous lesions.

    Meng Li

    Full Text Available OBJECTIVE: To evaluate the feasibility, effectiveness, and safety of reinnervation of the bilateral posterior cricoarytenoid (PCA muscles using the left phrenic nerve in patients with bilateral vocal fold paralysis. METHODS: Forty-four patients with bilateral vocal fold paralysis who underwent reinnervation of the bilateral PCA muscles using the left phrenic nerve were enrolled in this study. Videostroboscopy, perceptual evaluation, acoustic analysis, maximum phonation time, pulmonary function testing, and laryngeal electromyography were performed preoperatively and postoperatively. Patients were followed-up for at least 1 year after surgery. RESULTS: Videostroboscopy showed that within 1 year after reinnervation, abductive movement could be observed in the left vocal folds of 87% of patients and the right vocal folds of 72% of patients. Abductive excursion on the left side was significantly larger than that on the right side (P 0.05. No patients developed immediate dyspnea after surgery, and the pulmonary function parameters recovered to normal reference value levels within 1 year. Postoperative laryngeal electromyography confirmed successful reinnervation of the bilateral PCA muscles. Eighty-seven percent of patients in this series were decannulated and did not show obvious dyspnea after physical activity. Those who were decannulated after subsequent arytenoidectomy were not included in calculating the success rate of decannulation. CONCLUSIONS: Reinnervation of the bilateral PCA muscles using the left phrenic nerve can restore inspiratory vocal fold abduction to a physiologically satisfactory extent while preserving phonatory function at the preoperative level without evident morbidity.

  3. Facial paralysis after superficial parotidectomy: analysis of possible predictors of this complication

    Directory of Open Access Journals (Sweden)

    Renato Fortes Bittar

    Full Text Available ABSTRACT INTRODUCTION: Salivary gland tumors represent 3-10% of all head and neck neoplasms. These tumors occur predominantly in major salivary glands. The parotid gland is affected most often, ranging from 36.6% to 83%. The pleomorphic adenoma comprises 45-60% of all salivary gland tumors. Several surgical approaches have been described to treat this tumor. Lesion of the facial nerve is one of the most serious complications that can occur after parotid gland surgery. OBJECTIVES: To determine possible predictive factors related to the occurrence of peripheral facial paralysis (PFP after superficial parotidectomy in the surgical treatment of the pleomorphic adenomas of the parotid gland. METHODS: This was a primary, observational, case-control study performed through the revision of patients' charts and histopathological reports. Data was obtained from 1995 to 2014. The analyzed events were: tumor's length and depth; duration of the disease referred by the patient (more than 1, 5 or 10 years; primary or secondary surgical approach. RESULTS: The analysis showed that tumor lengths equal or superior to 3.0 cm were a risk factor of PFP with an odds ratio of 3.98 (p = 0.0310. Tumor depths equal or superior to 2.0 cm were also a risk factor with an odds ratio of 9.5556 (p = 0.0049. When the tested event was secondary surgery to recurrent tumors we have found an odds ratio of 6.7778 (p = 0.0029. CONCLUSION: Tumors with 3.0 cm or more in length and/or 2.0 cm or more in depth have a significant higher risk of facial nerve injury. Secondary surgery to recurrent tumors also has a much higher risk of evolving with facial palsy after superficial parotidectomy.

    A 3{sup 1}/{sub 2}-year-old child developed unilateral diaphragmatic paralysis after chest drain insertion. Plain chest X-ray demonstrated paravertebral positioning of the chest-tube tip, and magnetic resonance imaging revealed hematomas in the region of the chest-tube tip and the phrenic nerve fibers. The trauma to the phrenic nerve was apparently secondary to malposition of the chest tube. This is a rare complication and has been reported mainly in neonates. Radiologists should notify the treating physicians that the correct position of a chest drain tip is at least 2 cm distant from the vertebrae. (orig.)

    2017-07-01

    Full Text Available Injuries to the conus medullaris and cauda equina portions of the spinal cord result in neurological impairments, including paralysis, autonomic dysfunction, and pain. In experimental studies, earlier investigations have shown that a lumbosacral ventral root avulsion (VRA injury results in allodynia, which may be ameliorated by surgical replantation of the avulsed ventral roots. Here, we investigated the long-term effects of an L6 + S1 VRA injury on the plasticity of three populations of afferent projections to the dorsal horn in rats. At 8 weeks after a unilateral L6 + S1 VRA injury, quantitative morphological studies of the adjacent L5 dorsal horn showed reduced immunoreactivity (IR for the vesicular glutamate transporter, VGLUT1 and isolectin B4 (IB4 binding, whereas IR for calcitonin gene-related peptide (CGRP was unchanged. The IR for VGLUT1 and CGRP as well as IB4 binding was at control levels in the L5 dorsal horn at 8 weeks following an acute surgical replantation of the avulsed L6 + S1 ventral roots. Quantitative morphological studies of the L5 dorsal root ganglia (DRGs showed unchanged neuronal numbers for both the VRA and replanted series compared to shams. The portions of L5 DRG neurons expressing IR for VGLUT1 and CGRP, and IB4 binding were also the same between the VRA, replanted, and sham-operated groups. We conclude that the L5 dorsal horn shows selective plasticity for VGLUT1 and IB4 primary afferent projections after an L6 + S1 VRA injury and surgical repair.

    Acute flaccid paralysis (AFP) is clinical presentation marked by acute onset of weakness and reduced tone. Aetiologies of AFP are diverse including infectious agents, trauma or autoimmune reaction. Currently only three countries in the world that are Nigeria, Pakistan and Afghanistan have endemic poliomyelitis. Pakistan's polio crisis represents one of the last hurdles in a 23-year campaign run by the World Health Organization. Bannu due to its geographical location stands out to be one of highest risk areas for Poliomyelitis. The objective of this study was to determine frequency of AFP and their aetiologies in District of Bannu during time period of four years from 2007 to 2011. It was a cross-sectional descriptive study. Data was collected from EDO office District Bannu and analysed using Microsoft Excel 2007. Results: During this period there were 180 cases of AFP in district Bannu. 15% of cases were diagnosed as Guillian Barre Syndrome, making it the leading aetiology. Only 3 (1.66%) cases were diagnosed with Poliomyelitis. Out of 180 AFP cases 104 cases were male and 76 cases were female. Bannu needs enthusiastic educational and vaccination campaigns to eradicate Polio from the area and henceforth from the Pakistan.

  11. Astrocyte matricellular proteins that control excitatory synaptogenesis are regulated by inflammatory cytokines and correlate with paralysis severity during experimental autoimmune encephalomyelitis

    Directory of Open Access Journals (Sweden)

    Pennelope K. Blakely

    2015-10-01

    Full Text Available The matricellular proteins, secreted protein acidic and rich in cysteine (SPARC and SPARC-like 1 (SPARCL1, are produced by astrocytes and control excitatory synaptogenesis in the central nervous system. While SPARCL1 directly promotes excitatory synapse formation in vitro and in the developing nervous system in vivo, SPARC specifically antagonizes the synaptogenic actions of SPARCL1. We hypothesized these proteins also help maintain existing excitatory synapses in adult hosts, and that local inflammation in the spinal cord alters their production in a way that dynamically modulates motor synapses and impacts the severity of paralysis during experimental autoimmune encephalomyelitis (EAE in mice. Using a spontaneously remitting EAE model, paralysis severity correlated inversely with both expression of synaptic proteins and the number of synapses in direct contact with the perikarya of motor neurons in spinal grey matter. In both remitting and non-remitting EAE models, paralysis severity also correlated inversely with sparcl1:sparc transcript and SPARCL1:SPARC protein ratios directly in lumbar spinal cord tissue. In vitro, astrocyte production of both SPARCL1 and SPARC was regulated by T cell-derived cytokines, causing dynamic modulation of the SPARCL1:SPARC expression ratio. Taken together, these data support a model whereby proinflammatory cytokines inhibit SPARCL1 and/or augment SPARC expression by astrocytes in spinal grey matter that, in turn, cause either transient or sustained synaptic retraction from lumbar spinal motor neurons thereby regulating hind limb paralysis during EAE. Ongoing studies seek ways to alter this SPARCL1:SPARC expression ratio in favor of synapse reformation/maintenance and thus help to modulate neurologic deficits during times of inflammation. This could identify new astrocyte-targeted therapies for diseases such as multiple sclerosis.

    Full Text Available Objective. Autologous fat injection laryngoplasty is ineffective for some patients with iatrogenic vocal fold paralysis, and additional laryngeal framework surgery is often required. An acoustically measurable outcome predictor for lipoinjection laryngoplasty would assist phonosurgeons in formulating treatment strategies. Methods. Seventeen thyroid surgery patients with unilateral vocal fold paralysis participated in this study. All subjects underwent lipoinjection laryngoplasty to treat postsurgery vocal hoarseness. After treatment, patients were assigned to success and failure groups on the basis of voice improvement. Linear prediction analysis was used to construct a new voice quality indicator, the number of irregular peaks (NIrrP. It compared with the measures used in the Multi-Dimensional Voice Program (MDVP, such as jitter (frequency perturbation and shimmer (perturbation of amplitude. Results. By comparing the [i] vowel produced by patients before the lipoinjection laryngoplasty (AUC = 0.98, 95% CI = 0.78–0.99, NIrrP was shown to be a more accurate predictor of long-term surgical outcomes than jitter (AUC = 0.73, 95% CI = 0.47–0.91 and shimmer (AUC = 0.63, 95% CI = 0.37–0.85, as identified by the receiver operating characteristic curve. Conclusions. NIrrP measured using the LP model could be a more accurate outcome predictor than the parameters used in the MDVP.

    Summary Background: Sjögren syndrome (SS) is an autoimmune-lymphoproliferative disorder characterized by mononuclear cell infiltration of exocrine glands. Clinically, Sjögren syndrome (SS) has a wide spectrum, varying from autoimmune exocrinopathy to systemic involvement. There have been few cases reporting that primary SS developed with distal renal tubular acidosis clinically. Case Report: Here, we present a case with primary Sjögren syndrome accompanied by hypopotassemic paralysis due to renal tubular acidosis. Severe hypopotassemia, hyperchloremic metabolic acidosis, alkaline urine and disorder in urinary acidification test were observed in the biochemical examination of the 16-year-old female patient, who had applied to our clinic for extreme loss of muscle force. After the examinations it was determined that the patient had developed Type 1 RTA (distal RTA) due to primary Sjögren syndrome. Potassium and alkaline replacement was made and an immediate total recovery was achieved. Conclusions: Hypopotassemic paralysis due to primary Sjögren syndrome is a rare but severe disorder that could lead to death if not detected early and cured appropriately. Thus, effective treatment should be immediately initiated in cases where severe hypopotassemia is accompanied by metabolic acidosis, and the cases should also be examined for extraglandular involvement of SS.

    Full Text Available Three cases of acute flaccid paralysis (AFP with preceding fever are described. One patient had a quadriparesis with a florid meningoencephalitic picture and the other two had asymmetric flaccid paralysis with fasciculations at the onset of illness. Magnetic resonance imaging in two cases showed prominent hyperintensitities in the spinal cord and brainstem with prominent involvement of the grey horn (polio-myelitis. Cerebrospinal fluid (CSF polymerase chain reaction was positive for West Nile virus (WNV in the index patient. All three cases had a positive WNV immunoglobulin M antibody in serum/CSF and significantly high titer of WNV neutralizing antibody in serum, clearly distinguishing the infection from other Flaviviridae such as Japanese encephalitis. WNV has been recognized in India for many decades; however, AFP has not been adequately described. WNV is a flavivirus that is spread by Culex mosquitoes while they take blood meals from humans and lineage 1 is capable of causing a devastating neuro-invasive disease with fatal consequences or severe morbidity. We describe the first three laboratory confirmed cases of WNV induced AFP from Kerala and briefly enumerate the salient features of this emerging threat.

    The motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus in patients with oropharyngeal dysphagia is still not entirely understood. High-resolution manometry (HRM) was recently added to the armamentarium for the study of this area. This study aims to describe HRM findings in patients with vagal paralysis. Sixteen patients (mean age 54 years, 69% females) with oropharyngeal dysphagia due to unilateral vagal paralysis were prospectively studied. All patients underwent HRM. Motility of the UES and at the topography of the velopharynx and epiglottis were recorded. (1) UES relaxation is compromised in a minority of patients, (2) epiglottis pressure does not follow a specific pattern, (3) vellum is hypotonic in half of the patients, (4) dysphagia is related to a low pharyngeal pressure, not to a flow obstruction at the level of the UES, and (5) aspiration is related to low pressures at the level of the UES and epiglottis and higher pressures at the level of the vellum. Pharyngeal motility is significantly impaired in patients with oropharyngeal dysphagia and unilateral vagal paralysis. In half of the cases, UES resting pressure is preserved due to unilateral innervation and relaxation is normal in most patients. Dysphagia therapy in these patients must be directed toward improvement in the oropharyngeal motility not at the UES.

    Full Text Available Ethylene glycol (EG may be consumed accidentally or intentionally, usually in the form of antifreeze products or as an ethanol substitute. EG is metabolized to toxic metabolites. These metabolites cause metabolic acidosis with increased anion gap, renal failure, oxaluria, damage to the central nervous system and cranial nerves, and cardiovascular instability. Early initiation of treatment can reduce the mortality and morbidity but different clinical presentations can cause delayed diagnosis and poor prognosis. Herein, we report a case with the atypical presentation of facial paralysis, hematuria, and kidney failure due to EG poisoning which progressed to end stage renal failure and permanent right peripheral facial nerve palsy.

    Full Text Available Objectives: The aim of this study is to evaluate the efficacy and the safety of Sanyak pharmacopuncture therapy for the treatment of peripheral facial paralysis patients. Methods: This study was a retrospective investigation of a total of 70 patients who were inpatients of the Oriental Hospital of Daejeon University between January 1, 2011, and May 31, 2012, and who were diagnosed as having peripheral facial paralysis by physical examination, the patients received three different interventions. Eleven (11 patients were treated with acupuncture and alcohol Dioscorea rhizoma pharmacopuncture (ADG, 25 patients with acupuncture and distillation Dioscorea rhizoma pharmacopuncture (DDG, and 34 patients with acupuncture and non-Dioscorea rhizoma pharmacopuncture (NDG. The resulting data were analyzed. Results: The changed H-B grades indicated significant improvements in all three groups, and the ADG and the DDG groups showed significant results after two weeks of treatment when compared to the NDG group. The changed y-Scores indicated significant improvements in all three groups, and the ADG group showed significant results after 10 and 15 days of treatment when compared to the NDG group. Dioscorea rhizoma pharmacopuncture may be safe for the human body because in most cases, the only abnormal finding was the pain could by the application of pharmacopuncture. Conclusions: The results of this study suggest that Oriental medical treatment with dioscoreae Rhizoma (Sanyak pharmacopuncture complex therapy may be effective and safe in patient with peripheral facial paralysis

    The relationship between specific types of stressors (eg, teammates, coach) and acute versus overuse injuries is not well understood. To examine the roles of different types of stressors as well as the effect of motivational climate on the occurrence of acute and overuse injuries. Players in the Norwegian elite female football league (n=193 players from 12 teams) participated in baseline screening tests prior to the 2009 competitive football season. As part of the screening, we included the Life Event Survey for Collegiate Athletes and the Perceived Motivational Climate in Sport Questionnaire (Norwegian short version). Acute and overuse time-loss injuries and exposure to training and matches were recorded prospectively in the football season using weekly text messaging. Data were analysed with Bayesian logistic regression analyses. Using Bayesian logistic regression analyses, we showed that perceived negative life event stress from teammates was associated with an increased risk of acute injuries (OR=1.23, 95% credibility interval (1.01 to 1.48)). There was a credible positive association between perceived negative life event stress from the coach and the risk of overuse injuries (OR=1.21, 95% credibility interval (1.01 to 1.45)). Players who report teammates as a source of stress have a greater risk of sustaining an acute injury, while players reporting the coach as a source of stress are at greater risk of sustaining an overuse injury. Motivational climate did not relate to increased injury occurrence.

    The objective of this study was to develop and evaluate the voice outcomes of an approach to arytenoid adduction (AA) for unilateral vocal cord paralysis through fenestration of the thyroid ala. Thirty-two patients with unilateral vocal cord paralysis underwent laryngoplasty using an approach to AA performed through fenestration of the thyroid ala combined with type I thyroplasty. Thirty-two patients with unilateral vocal cord paralysis were treated between October 2004 and February 2008. In all cases, maximum phonation time (MPT) and mean airflow rate (MFR) were measured before and after the operation. The voices were analyzed using shimmer and jitter. Two surgical windows were made in the lower part of the thyroid ala. The anterior one was for typical type I thyroplasty and the posterior one was for arytenoid adduction (AA). The locations of the two windows were determined based on three-dimensional computer tomography (3DCT) data. AA was performed by muscular process through the posterior window without releasing the cricothyroid joint. The operations were performed under local anesthesia with sedation. Vocal cord medialization was confirmed endoscopically during the operation. Twenty-nine of the 32 patients achieved an MPT of over 10 s after surgery. The other 3 cases, whose MPTs were 9 s after the operation, had low breathing capacity because of lung disease and normal side vocal cord sulcus. The MFRs, which ranged from 236 to 1908 ml/s before the operation, improved to under 200 ml/s except in 3 patients, whose MFRs were 210 ml/s, 214 ml/s and 216 ml/s. Jitter and shimmer improved significantly after the operation. Perceptual evaluation using the GRBAS scale also improved significantly. Our new procedure simplified the combination of AA and type I thyroplasty because the two treatments can be performed in the same operating field, obtaining good voice improvement. Determination of the surgical approach using 3DCT and endoscopic vocal cord observation may

    Effective therapy for chronic radiation injuries, such as ulcers, is prone to infection. Stiffness is expected since the therapeutic radiation often involves wider and deeper tissues and often requires extensive debridement and reconstruction, which are not sometimes appropriate for elderly and compromised hosts. Autologous adipose-derived regenerative cells (ADRCs) are highly yielding, forming relatively elderly aged consecutive 10 cases, 63.6±14.9 y (52-89 y), with mean radiation dose of 75.0±35.4 Gy (50-120 Gy) were included with at least 10-month follow-up. Minimal debridement and ADRC injection in the wound bed and margin along with the injection of mixture of fat and ADRCs in the periphery were tested for efficacy and regenerated tissue quality by clinically as well as imaging by computed tomography and magnetic resonance imaging. Uncultured ADRCs of 1.6±1.3 x 10 7 cells were obtained. All cases healed uneventfully after 6.6±3.2 weeks (2-10 weeks) post-operatively. The done site morbidity was negligible and without major complications, such as paralysis or massive haematoma. The regenerated tissue quality was significantly superior to the pre-operative one and the mixture of fat and ADRCs connected to the intact tissue was very soft and pliable. Mean follow-up at 1.9±0.8 y (0.9-2.9 y) revealed no recurrence or new ulceration after treatment. Thus, the ADRCs treatment for decades-long radiation injuries is effective, safe and improves the quality of wounds. (authors)

    Objectives To estimate the prevalence and causes of functional paralysis in the United States. Methods We used the 2013 US Paralysis Prevalence & Health Disparities Survey to estimate the prevalence of paralysis, its causes, associated sociodemographic characteristics, and health effects among this population. Results Nearly 5.4 million persons live with paralysis. Most persons with paralysis were younger than 65 years (72.1%), female (51.7%), White (71.4%), high school graduates (64.8%), married or living with a partner (47.4%), and unable to work (41.8%). Stroke is the leading cause of paralysis, affecting 33.7% of the population with paralysis, followed by spinal cord injury (27.3%), multiple sclerosis (18.6%), and cerebral palsy (8.3%). Conclusions According to the functional definition, persons living with paralysis represent a large segment of the US population, and two thirds of them are between ages 18 and 64 years. Targeted health promotion that uses inclusion strategies to account for functional limitations related to paralysis can be undertaken in partnership with state and local health departments.

    All 449 breast cancer patients treated with post-operative radiotherapy to the breast and lymph nodes between 1982 and 1984 have been followed for 3-5.5 years. In this group two different fractionation schedules were used, one five times a fortnight and one daily, both over 6 weeks. The calculated dose to the brachial plexus was 45 Gy in 15 fractions or 5e Gy in 30 fractions. These schedules are equivalent doses using the standard NSD formula. The diagnosis of a brachial plexus injury was made clinically and computed tomography from recurrent disease. The actuarial incidence of a radiation-induced brachial plexus injury for the whole group was 4.9% at 5.5 years. No cases were seen in the first 10 months following radiotherapy. The incidence rises between 1 and 4 years and then starts to plateau. When the large fraction size group is compared with the small fraction size group the incidence at 5.5 years is 5.9% and 1.0%, respectively (p 0.09). Two different treatment techniques were used in this group but were not found to contribute to the probability of developing a brachial plexud injury. It is suggested that radiation using large doses per fraction are less well tolerated by the brachial plexus than small doses per fraction; a commonly used fractionation schedule such as 45 Gy in 15 fractions may give unacceptably high brachial plexus morbidity; and the of small doses per fraction or avoiding lymphatic irradiation is advocated.

    1. To determine the prevalence of left vocal cord paralysis (LVCP) post patent ductus arteriosus (PDA) ligation at a Tertiary Care Centre. 2. To identify risk factors associated with LVCP. 3. To identify co-morbidities associated with LVCP. 4. To determine the frequency of pre- and post-operative nasopharyngolaryngoscopic (NPL) examination in this patient population. Retrospective chart review of all infants who underwent PDA ligation surgery at a tertiary care academic hospital between July 2003 and July 2010. Data on patient age, gender, weight, method of PDA ligation, and results of NPL scoping were collected, as well as patient co-morbidities post PDA ligation. One hundred and fifteen patients underwent PDA ligation surgery. Four patients were excluded due to bilateral vocal cord paralysis. Of the remaining 111 patients, nineteen patients (17.1%) were found to have LVCP. Low birth weight was identified as a significant risk factor for LVCP (p=0.002). Gastroesophageal reflux was identified as a significant co-morbidity associated with LVCP post PDA ligation (p=0.002). Only 0.9% of patients were scoped pre-operatively, and 27.9% were scoped postoperatively. LVCP is associated with multiple morbidities. The authors strongly recommend routine post-operative scoping of all patients post PDA ligation surgery, and preoperative scoping when possible. A prospective study is warranted, in order to confirm the prevalence of LVCP as well as risk factors and associated co-morbidities. Crown Copyright © 2012. Published by Elsevier Ireland Ltd.

    Intralaryngeal muscle synkinesis associated with unilateral vocal fold paralysis (UVFP) is thought to preserve thyroarytenoid-lateral cricoarytenoid muscle complex tone, resulting in a better voice despite the presence of vocal fold paralysis (VFP). This study compares voice handicap in patients with unilateral VFP (UVFP) with and without evidence of adductory synkinesis on laryngeal electromyography (LEMG). Retrospective review of LEMG data and Voice Handicap Index-10 (VHI-10) scores of patients diagnosed with permanent UVFP. LEMG was performed within 1 to 6 months post onset of UVFP. Patients were stratified into two groups: 1) recurrent laryngeal nerve (RLN) neuropathy with synkinesis and 2) RLN neuropathy without synkinesis. Synkinesis was diagnosed when the sniff to phonation maximum amplitude ratio was ≥0.65. VHI-10 scores at 6-month follow-up were recorded. Four hundred forty-nine patients with UVFP and who had an LEMG were reviewed. Eighty-three patients met the inclusion criteria, with 16 in group 1 and 67 in group 2. There was no significant difference between the groups with regard to age, timing of LEMG from onset of VFP, number of patients undergoing temporary vocal fold injection or use of off-label nimodipine. Average VHI-10 scores at 6 months post onset of VFP were 14.4 ± 10.6 for patients with LEMG-identified synkinesis (group 1) and 21.0 ± 10.1 for patients with no LEMG evidence of synkinesis (group 2). This was statistically significant (P = .02). Patients with unilateral vocal fold paralysis and LEMG evidence of laryngeal synkinesis are more likely to have less perceived voice handicap than those without synkinesis. 4.

    Nearly 6 million people in the United States are currently living with paralysis in which 23% of the cases are related to spinal cord injury (SCI). Miniaturized closed-loop neural interfaces have the potential for restoring function and mobility lost to debilitating neural injuries such as SCI by leveraging recent advancements in bioelectronics and a better understanding of the processes that underlie functional and anatomical reorganization in an injured nervous system. This paper describes our current progress towards developing a miniaturized brain-machine-spinal cord interface (BMSI) that is envisioned to convert in real time the neural command signals recorded from the brain to electrical stimuli delivered to the spinal cord below the injury level. Specifically, the paper reports on a corticospinal interface integrated circuit (IC) as a core building block for such a BMSI that is capable of low-noise recording of extracellular neural spikes from the cerebral cortex as well as muscle activation using intraspinal microstimulation (ISMS) in a rat with contusion injury to the thoracic spinal cord. The paper further presents results from a neurobiological study conducted in both normal and SCI rats to investigate the effect of various ISMS parameters on movement thresholds in the rat hindlimb. Coupled with proper signal-processing algorithms in the future for the transformation between the cortically recorded data and ISMS parameters, such a BMSI has the potential to facilitate functional recovery after an SCI by re-establishing corticospinal communication channels lost due to the injury.

    Full Text Available We report here the protective effects of a methanol extract from a cultivated strain of the red seaweed, Chondrus crispus, against β-amyloid-induced toxicity, in a transgenic Caenorhabditis elegans, expressing human Aβ1-42 gene. The methanol extract of C. crispus (CCE, delayed β-amyloid-induced paralysis, whereas the water extract (CCW was not effective. The CCE treatment did not affect the transcript abundance of amy1; however, Western blot analysis revealed a significant decrease of Aβ species, as compared to untreated worms. The transcript abundance of stress response genes; sod3, hsp16.2 and skn1 increased in CCE-treated worms. Bioassay guided fractionation of the CCE yielded a fraction enriched in monogalactosyl diacylglycerols (MGDG that significantly delayed the onset of β-amyloid-induced paralysis. Taken together, these results suggested that the cultivated strain of C. crispus, whilst providing dietary nutritional value, may also have significant protective effects against β-amyloid-induced toxicity in C. elegans, partly through reduced β-amyloid species, up-regulation of stress induced genes and reduced accumulation of reactive oxygen species (ROS.

    Stimulation of the phrenic nerve by supplying an electrical impulse to the neck during fluoroscopy or real-time ultrasound (sonoscopy) of the diaphragm allows more precise functional evaluation than fluoroscopy and/or sonoscopy alone. This is especially true of patients who are unable to cooperate because the are on a ventilator, unconscious, or very young. The authors cite cases in which diaphragmatic paralysis was diagnosed by conventional methods but stimulation of the phrenic nerve demonstrated good diaphragmatic motion, leading to a change in prognosis in some cases and a change in therapy in others.

    The occurrence of deep venous thrombosis (DVT) was studied in the series of 23 consecutive patients with acute spinal cord injury and 14 immobilized patients with spinal fractures without paralysis. The incidence of DVT in paralyzed patients was 100% as detected by the 125 I-labeled fibrinogen test and confirmed by contrast venography, and 64% as detected by repeated clinical examinations and confirmed by contrast venography. The respective incidence of DVT in nonparalyzed patients with spinal fractures was 0%. The diagnosis of DVT was reached earlier with the radiofibrinogen test than with the clinical followup (5 days vs. 25 days). Two of the 23 paralyzed patients (9%) developed nonfatal clinical pulmonary embolism (PE). There were no differences in the values of routine coagulation tests. The result justifies prophylactic anticoagulant therapy in all cases of spinal cord injury during the acute post-traumatic phase

    Acute peripheral facial paralysis is a disease with acute palsy flaccid of mimic muscles due to the damages to facial nerve either at facial nerve nucleus or beyond it. Because facial nerve is the longest cranial nerve which traverses in the bony fallopian canal, any lesion of the facial nerve could cause paralysis of the ipsilateral face. Acute peripheral dysfunction of the facial nerve becomes one of the most common otology diseases. It is hard to locate the lesion of facial nerve and to choose proper therapeutic regiment as soon as possible because of the complexity of the anatomy of facial nerve. So it is necessary to establish acute facial paralysis animal model to prompt further study of this disease. This article approached the methods to found acute facial paralysis animal models, analyzed the deficiencies existing in the models and suggested the new thread of this research.%急性周围性面瘫是面神经核及其以下面神经损伤导致的急性面部表情肌的迟缓性麻痹.因面神经是在骨管内行程最长的颅神经,易受外界因素影响、侵犯,所以急性周围性面瘫是耳科疾病中的常见病.且因面神经行程复杂,增大了面瘫定位和选择治疗方案的难度.急性周围性面瘫动物模型的建立为深入研究面瘫提供了一个手段.本文从面瘫动物造模机制、特点、适用范围及效度、目前存在的问题等方面对现常用的面瘫动物模型的研究现状进行综述.

    To review the current evidence for the epidemiology of pediatric injuries in martial arts. The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure. Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

    There were no differences between Canada and Japan in the prevalence and symptoms of sleep paralysis (SP), but many more Canadians considered SP to be a dream. The difference was considered to be derived from the fact that there is a common expression for SP in Japan but there is not one in Canada. Then, we investigated why there are individuals who consider SP to be a dream and others who do not, and found that many Japanese who regarded it as a dream did not report the symptom of 'unable to move', while in Canada, self-evaluation of spirituality was different between the two groups.

  19. Periauricular Keloids on Face-Lift Scars in a Patient with Facial Nerve Paralysis

    Directory of Open Access Journals (Sweden)

    Masayo Aoki, MD, PhD

    2017-07-01

    Full Text Available Summary:. Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis. A 51-year-old Japanese man presented with abnormal proliferative skin masses in bilateral periauricular scars. Seventeen years before, he had a cerebral infarction that resulted in permanent bilateral facial nerve paralysis. Three years before presentation, the patient underwent face-lift surgery with periauricular incisions. We diagnosed multiple keloids. We removed the masses surgically, closed the wounds with sutures in the superficial musculoaponeurotic system layer to reduce tension on the wound edges, reconstructed the earlobes with local skin flaps, and provided 2 consecutive days of radiotherapy. The wounds/scars were managed with steroid plasters and injections. Histology confirmed that the lesions were keloids. Ten months after surgery, the lesions did not exhibit marked regrowth. The keloids appeared to be caused by the patient's helmet, worn during his 3-hour daily motorcycle rides, which placed repeated tension on the periauricular area. This rare case illustrates how physical force contributes to auricular and periauricular keloid development and progression. It also shows that when performing surgery with periauricular incisions, care should be taken to eliminate wound/scar stretching.

    Full Text Available BACKGROUND Craniospinal injuries are most important cause of mortality and long-term morbidity. There are no studies in our setup to develop a protocol for management of craniospinal injury victims, their transportation, risk factors for severity and factors that determining the prognosis, hence this study. Even now, it is important that the ‘108’ ambulance services was not operating in our place, which had given all the support of transportation in a scientific manner. In 1999-2000, there were 37,072 accidents in Kerala; of this, 9184 came to medical college, Trivandrum; 208 (18% out of 1111 craniospinal injuries died. The primary goal of transportation is to transfer a patient to an emergency room with all system stabilised in order to enhance the potential for maximal neurological recovery and to avoid any additional secondary injury. MATERIALS AND METHODS Is delay in reaching a tertiary care centre, a determinant of bad outcome as measured by case fatality and paralysis in spinal injuries?.

    Gunshot wounds to the head (GSWH) account for the majority of penetrating brain injuries, and are the most lethal. Since they are rare in Europe, the number of neurosurgeons who have experienced this type of traumatic injury is decreasing, and fewer cases are reported in the literature. We describe a case of gunshot to the temporal bone in which the bullet penetrated the skull resulting in the facial nerve paralysis. It was excised with the transotic approach. Microsurgical anastomosis among the masseteric nerve and the facial nerve was performed. GSWH are often devastating. The in-hospital mortality for civilians with penetrating craniocerebral injury is very high. Survivors often have high rate of complications. When facial paralysis is present, masseteric-facial direct neurorraphy represent a good treatment.

    1984-01-01

    One hundred consecutive patients admitted to the National Spinal Injuries Centre, Stoke Mandeville Hospital, with pressure sores were studied to assess the relative importance of factors known to predispose to the development of scores. Loss of feeling was critical, because patients were unable to appreciate pain when the sore was developing. Risk of developing a sore increased with age, but duration of the paralysis was of equal importance. After discharge from hospital the presence of a caring relative or friend was essential for survival. Many patients developed sores because of poor facilities at home or inappropriate advice from those who looked after them. An even more distressing factor was the number of patients who developed sores in hospital owing to inadequate nursing care. There are relatively few paralysed patients in the community, but the lessons learnt in this study may be applied to all patients with orthopaedic injuries and to geriatric patients with limited mobility. Nursing and medical staff must turn patients regularly and ensure that there is proper equipment to relieve pressure on the skin. Patients should not be allowed to sit in a chair if they develop a sacral or trochanteric sore. More effort should be directed towards the appropriate education of patients, their relatives, and all those who are concerned with their welfare. Images FIG 1 FIG 2 FIG 3 PMID:6439284

    Full Text Available Sleep paralysis (SP is a dissociative state that occurs mainly during awakening. SP is characterized by altered motor, perceptual, emotional and cognitive functions, such as inability to perform voluntary movements, visual hallucinations, feelings of chest pressure, delusions about a frightening presence and, in some cases, fear of impending death. Most people experience SP rarely, but typically when sleeping in supine position; however, SP is considered a disease (parasomnia when recurrent and/or associated to emotional burden. Interestingly, throughout human history, different peoples interpreted SP under a supernatural view. For example, Canadian Eskimos attribute SP to spells of shamans, who hinder the ability to move, and provoke hallucinations of a shapeless presence. In the Japanese tradition, SP is due to a vengeful spirit who suffocates his enemies while sleeping. In Nigerian culture, a female demon attacks during dreaming and provokes paralysis. A modern manifestation of SP is the report of alien abductions, experienced as inability to move during awakening associated with visual hallucinations of aliens. Furthermore, SP is a significant example of how a specific biological phenomenon can be interpreted and shaped by different cultural contexts. In order to further explore the ethnopsychology of SP, the Pisadeira, a character of Brazilian folklore originated in the country’s Southeast, but also found in other regions with variant names, has been reviewed. Pisadeira is described as a crone with long fingernails who lurks on roofs at night and tramples on the chest of those who sleep on a full stomach with the belly up. This legend is mentioned in many anthropological accounts; however, we found no comprehensive reference on the Pisadeira from the perspective of sleep science. Here we aim to fill this gap. We first review the neuropsychological aspects of SP, and then present the folk tale of the Pisadeira. Finally, we summarize the

    Despite overuse injuries being previously described as the most frequent in ballet, there are no studies on professional dancers providing the specific clinical diagnoses or type of injury based on the discipline. Overuse injuries are the most frequent injuries in ballet, with differences in the type and frequency of injuries based on discipline. Cross-sectional study; Level of evidence, 3. This was a descriptive cross-sectional study performed between January 1, 2005, and October 10, 2010, on injuries occurring in professional dancers from leading Spanish dance companies who practiced disciplines such as classical, neoclassical, contemporary, and Spanish ballet. Data, including type of injury, were obtained from specialized medical services at the Trauma Service, Fremap, Madrid, Spain. A total of 486 injuries were evaluated, a significant number of which were overuse disorders (P ballet (82.60%). Injuries were more frequent among female dancers (75.90%) and classical ballet (83.60%). A statistically significant prevalence of patellofemoral pain syndrome was found in the classical discipline (P = .007). Injuries of the adductor muscles of the thigh (P = .001) and of the low back facet (P = .02) in the Spanish ballet discipline and lateral snapping hip (P = .02) in classical and Spanish ballet disciplines were significant. Overuse injuries were the most frequent injuries among the professional dancers included in this study. The prevalence of injuries was greater for the most technically demanding discipline (classical ballet) as well as for women. Patellofemoral pain syndrome was the most prevalent overuse injury, followed by Achilles tendinopathy, patellar tendinopathy, and mechanical low back pain. Specific clinical diagnoses and injury-based differences between the disciplines are a key factor in ballet.

    Professor YANG Jun 's experience of diagnosis and treatment for intractable facial paralysis is introduced. Professor YANG focuses on the thinking model that combines TCM, western medicine and acupuncture, and adopts the differentiation system that combines disease differentiation, syndrome differentiation and meridian differentiation; he adopts the treatment integrates etiological treatment, overall regulation, symptomatic treatment as well as acupuncture, moxibustion, medication and flash cupping. The acupoints of yangming meridians are mostly selected, and acupoints of governor vessel such as Dazhui (GV 14) and Jinsuo (GV 8) are highly valued. The multiple-needles shallow-penetration-insertion twirling lifting and thrusting technique are mostly adopted to achieve slow and mild acupuncture sensation; in addition, the facial muscles are pulled up with mechanics action. The intensive stimulation with electroacupuncture is recommended at Qianzheng (Extra), Yifeng (TE 17) and Yangbai (GB 14), which is given two or three treatments per week.

    To describe the mechanism, location and types of injury for all patients treated for trampoline-associated injuries at St Olav's University Hospital, Trondheim, Norway, from March 2001to October 2004. Patients were identified from a National Injury Surveillance System. All patients were asked to complete a standard questionnaire at their first visit at the hospital. Most data were recorded prospectively, but data on the mechanism of injury, the number of participants on the trampoline at the time of injury, adult supervision and whether the activity occurred at school or in another organised setting were collected retrospectively. A total of 556 patients, 56% male and 44% female, were included. The mean age of patients was 11 (range 1-62) years. 77% of the injuries occurred on the body of the trampoline, including falls on to the mat, collisions with another jumper, falls on to the frame or the springs, and performing a somersault, whereas 22% of the people fell off the trampoline. In 74% of the cases, more than two people were on the trampoline, with as many as nine trampolinists noted at the time of injury. For children Trampolining can cause serious injuries, especially in the neck and elbow areas of young children. The use of a trampoline is a high-risk activity. However, a ban is not supported. The importance of having safety guidelines for the use of trampolines is emphasised.

  10. Assembly of recombinant Israeli Acute Paralysis Virus capsids.

    Directory of Open Access Journals (Sweden)

    Junyuan Ren

    Full Text Available The dicistrovirus Israeli Acute Paralysis Virus (IAPV has been implicated in the worldwide decline of honey bees. Studies of IAPV and many other bee viruses in pure culture are restricted by available isolates and permissive cell culture. Here we show that coupling the IAPV major structural precursor protein ORF2 to its cognate 3C-like processing enzyme results in processing of the precursor to the individual structural proteins in a number of insect cell lines following expression by a recombinant baculovirus. The efficiency of expression is influenced by the level of IAPV 3C protein and moderation of its activity is required for optimal expression. The mature IAPV structural proteins assembled into empty capsids that migrated as particles on sucrose velocity gradients and showed typical dicistrovirus like morphology when examined by electron microscopy. Monoclonal antibodies raised to recombinant capsids were configured into a diagnostic test specific for the presence of IAPV. Recombinant capsids for each of the many bee viruses within the picornavirus family may provide virus specific reagents for the on-going investigation of the causes of honeybee loss.

    Chronic bee paralysis virus (CBPV) is responsible for chronic bee paralysis, an infectious and contagious disease in adult honey bees (Apis mellifera L.). A real-time RT-PCR assay to quantitate the CBPV load is now available. To propose this assay as a reference method, it was characterised further in an intra-laboratory study during which the reliability and the repeatability of results and the performance of the assay were confirmed. The qPCR assay alone and the whole quantitation method (from sample RNA extraction to analysis) were both assessed following the ISO/IEC 17025 standard and the recent XP U47-600 standard issued by the French Standards Institute. The performance of the qPCR assay and of the overall CBPV quantitation method were validated over a 6 log range from 10(2) to 10(8) with a detection limit of 50 and 100 CBPV RNA copies, respectively, and the protocol of the real-time RT-qPCR assay for CBPV quantitation was approved by the French Accreditation Committee.

    The abdomen is a big place even in a small person. Gastrointestinal trauma can result in injury to the stomach, small bowel, colon, or rectum. Traumatic causes include blunt or penetrating trauma, such as gunshot wounds, stabbings, motor vehicle collisions, and crush injuries. Nontraumatic causes include appendicitis, Crohn disease, cancer, diverticulitis, ulcerative colitis, blockage of the bowel, and chemotherapy. The mechanism of injury will affect both the nature and severity of any resulting injuries. Treatment must address the critical and emergent nature of these injuries as well as issues that affect all trauma situations, which include management of hemodynamic instability.

    Although injuries are recognized as a leading health problem in the military, the size of the problem is underestimated when only acute traumatic injuries are considered. Injury-related musculoskeletal conditions are common in this young, active population. Many of these involve physical damage caused by micro-trauma (overuse) in recreation, sports, training, and job performance. The purpose of this analysis was to determine the incidence of injury-related musculoskeletal conditions in the military services (2006) and describe a standardized format in which to categorize and report them. The subset of musculoskeletal diagnoses found to be injury-related in previous military investigations was identified. Musculoskeletal injuries among nondeployed, active duty service members in 2006 were identified from military medical surveillance data. A matrix was used to report and categorize these conditions by injury type and body region. There were 743,547 injury-related musculoskeletal conditions in 2006 (outpatient and inpatient, combined), including primary and nonprimary diagnoses. In the matrix, 82% of injury-related musculoskeletal conditions were classified as inflammation/pain (overuse), followed by joint derangements (15%) and stress fractures (2%). The knee/lower leg (22%), lumbar spine (20%), and ankle/foot (13%) were leading body region categories. When assessing the magnitude of the injury problem in the military services, injury-related musculoskeletal conditions should be included. When these injuries are combined with acute traumatic injuries, there are almost 1.6 million injury-related medical encounters each year. The matrix provides a standardized format to categorize these injuries, make comparisons over time, and focus prevention efforts on leading injury types and/or body regions.

    Horseback riding is more dangerous than motorcycle riding, skiing, football, and rugby. The purpose of this study was to identify the incidence and injury patterns, as well as risk factors associated with severe equestrian trauma. All patients with major equestrian injuries (injury severity score > or = 12) admitted between 1995 and 2005 were reviewed. A 46-question survey outlining potential rider, animal, and environmental risk factors was administered. Among 7941 trauma patients, 151 (2%) were injured on horseback (mean injury severity score, 20; mortality rate, 7%). Injuries included the chest (54%), head (48%), abdomen (22%), and extremities (17%). Forty-five percent required surgery. Survey results (55%) indicated that riders and horses were well trained, with a 47% recidivism rate. Only 9% of patients wore helmets, however, 64% believed the accident was preventable. Chest trauma previously has been underappreciated. This injury pattern may be a result of significant rider experience. Helmet and vest use will be targeted in future injury prevention strategies.

    To evaluate the prognostic and predictive value of electroneuronography (ENoG) in acute severe inflammatory facial paralysis, including Bell's palsy and Ramsay Hunt syndrome (RHS). Prospective observational study. Patients with acute severe facial paralysis of House-Brackmann (H-B) grade IV or worse and diagnosed with Bell's palsy or RHS were enrolled from August 2007 to July 2011. After treatment with oral corticosteroid, antiviral agent, and protective eye care, patients were followed up until recovery or 12 months from onset. Sixty-six patients with Bell's palsy and 22 with RHS were included. Multiple logistic regression analysis showed significant effect of ENoG value on recovery in both Bell's palsy and RHS. Values of ENoG were significantly worse in RHS than Bell's palsy. Chance of early recovery within 6 weeks after correction of ENoG effect was still significantly worse in RHS. Logistic regression analysis showed 90% chance of recovery within 6 months, expected with ENoG values of 69.2% degeneration (Bell's palsy) and 59.3% (RHS). The receiver operating characteristics (ROC) curves showed ENoG values of 82.5% (Bell's palsy) and 78.0% (RHS) as a critical cutoff value of nonrecovery until 1 year, with the best sensitivity and specificity. A higher chance of recovery was expected with better ENoG in Bell's palsy and RHS. Based on our data, nonrecovery is predicted in patients with ENoG value greater than 82.5% in Bell's palsy, and 78% in RHS. 4.

    After scald burn-injury, the intestinal immune system responds to maintain immune balance. In this regard CD4+T cells in Gut-Associated Lymphoid Tissues (GALT), like mesenteric lymph nodes (MLN) and Peyer's patches (PP) respond to avoid immune suppression following major injury such as burn. Therefore, we hypothesized that the gut CD4+T cells become dysfunctional and turn the immune homeostasis towards depression of CD4+ T cell-mediated adaptive immune responses. In the current study we show down regulation of mucosal CD4+ T cell proliferation, IL-2 production and cell surface marker expression of mucosal CD4+ T cells moving towards suppressive-type. Acute burn-injury lead to up-regulation of regulatory marker (CD25+), down regulation of adhesion (CD62L, CD11a) and homing receptor (CD49d) expression, and up-regulation of negative co-stimulatory (CTLA-4) molecule. Moreover, CD4+CD25+ T cells of intestinal origin showed resistance to spontaneous as well as induced apoptosis that may contribute to suppression of effector CD4+ T cells. Furthermore, gut CD4+CD25+ T cells obtained from burn-injured animals were able to down-regulate naïve CD4+ T cell proliferation following adoptive transfer of burn-injured CD4+CD25+ T cells into sham control animals, without any significant effect on cell surface activation markers. Together, these data demonstrate that the intestinal CD4+ T cells evolve a strategy to promote suppressive CD4+ T cell effector responses, as evidenced by enhanced CD4+CD25+ T cells, up-regulated CTLA-4 expression, reduced IL-2 production, tendency towards diminished apoptosis of suppressive CD4+ T cells, and thus lose their natural ability to regulate immune homeostasis following acute burn-injury and prevent immune paralysis.

    Despite intensified use of monovalent oral poliovirus type 1 vaccine and improved coverage of immunization campaigns, wild poliovirus type 1 persisted in Indian states of Uttar Pradesh and Bihar during 2006 to 2009. A serosurvey was conducted among cases of acute flaccid paralysis in the 25 high-polio-incidence districts of western Uttar Pradesh. Children were recruited by age group (6-11 months, 12-24 months, and 25-69 months) from among cases reported through the acute flaccid paralysis surveillance system between November 2008 and August 2009. Seroprevalence for type 1 wild poliovirus was >96.4% for each age group. The seroprevalence of wild poliovirus types 2 and 3 increased with age, from 36.7% to 73.4% for type 2 and from 39.0% to 74.1% for type 3. In addition to the number of type-specific vaccine doses, father's level of education, being from a Muslim family, height for age, and female sex were the socioeconomic risk factors associated with seronegativity to poliovirus. The seroprevalence and risk factors identified in this study were consistent with the epidemiology of polio, and the findings were instrumental in optimizing vaccination strategy in western Uttar Pradesh with respect to the choice of OPV types, the frequency of supplementary immunization campaigns, and the urgency to improve routine immunization services. © The Author 2014.

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year.

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year.

    Creation of symmetrical nasolabial folds (NLFs) is important in the management of the paralyzed face. Established techniques use a linear incision in the NLF, and technical refinements now allow the linear incision to be omitted. This retrospective case series was conducted in a tertiary care setting from February 2, 2017, to June 7, 2017. Participants were all patients (N = 21) with peripheral facial paralysis who underwent NLF modification that used the minimal nasolabial incision technique at the Massachusetts Eye and Ear Infirmary Facial Nerve Center from February 1, 2015, through August 31, 2016. Patient-reported outcome measures using the validated, quality-of-life Facial Clinimetric Evaluation (FaCE) Scale; clinician-reported facial function outcomes using a validated electronic clinician-graded facial paralysis assessment (eFACE); layperson assessment of the overall aesthetic outcome of the NLF; and expert-clinician scar assessment of the NLF. Of the 21 patients who underwent NLF modification that used the minimal nasolabial incision technique, 9 patients (43%) were female and 12 (57%) were male. The mean age was 41 (range, 9-90) years; 17 patients (81%) were adults (≥18 years) and 4 (19%) were children (<18 years). Overall, significant improvements were observed after NLF modification in all outcome measures as graded by both clinicians and patients. The mean (SD) scores for total eFACE were 60.7 (14.9) before the operation and 77.2 (8.9) after the operation (mean difference, 16.5 [95% CI, 8.5-24.2]; P < .001). The mean (SD) static eFACE scores were 61.4 (20.6) before the operation and 82.7 (12.4) after the operation (mean difference, 21.3 [95% CI, 10.7-31.9]; P < .001). The mean (SD) FaCE quality-of-life scores were 51.3 (20.1) before the operation and 70.3 (12.6) after the operation (mean difference, 19.0 [95% CI, 6.5-31.6]; P  =  .001).

    Full Text Available Locked-in syndrome (LIS is a rare diagnosis in which patients present with quadriplegia, lower cranial nerve paralysis, and mutism. It is clinically difficult to differentiate from other similarly presenting diagnoses with no standard approach for assessing such poorly responsive patients. The purpose of this case is to highlight the clinical differential diagnosis process and outcomes of a patient with LIS during acute inpatient rehabilitation. A 32-year-old female was admitted following traumatic brain injury. She presented with quadriplegia and mutism but was awake and aroused based on eye gaze communication. The rehabilitation team was able to diagnose incomplete LIS based on knowledge of neuroanatomy and clinical reasoning. Establishing this diagnosis allowed for an individualized treatment plan that focused on communication, coping, family training, and discharge planning. The patient was ultimately able to discharge home with a single caregiver, improving her quality of life. Continued evidence highlights the benefits of intensive comprehensive therapy for those with acquired brain injury such as LIS, but access is still limited for those with a seemingly poor prognosis. Access to a multidisciplinary, specialized team provides opportunity for continued assessment and individualized treatment as the patient attains more medical stability, improving long-term management.

    The running portion of the triathlon represents the final leg of the competition and, by some reports, the most important part in determining a triathlete's overall success. Although most triathletes spend most of their training time on cycling, running injuries are the most common injuries encountered. Common causes of running injuries include overuse, lack of rest, and activities that aggravate biomechanical predisposers of specific injuries. We discuss the running-associated injuries in the hip, knee, lower leg, ankle, and foot of the triathlete, and the causes, presentation, evaluation, and treatment of each.

    Full Text Available Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Seizures occurring in precarious situations and resulting in injuries are still an important concern for patients with epilepsy, their employers and their caregivers. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. These concerns seem valid because the hallmark of epilepsy, episodic impairment of consciousness and motor control, may occur during interictal EEG epileptiform discharges, even in the absence of a clinical seizure. In addition, psychomotor comorbidity and side effects of antiepileptic drugs may contribute to the risk of injuries in patients with epilepsy. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, epidemiological information about incidence of injuries has been conflicting and sparse. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based on non-selected populations of people with epilepsy have not shown an increased frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include: more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. Potentially the high rate of

    A convenient transgenic astrocytoma model in delta202 mice, homozygous for a construct encoding the early region of the SV40 virus genome, is described. In the offspring of crosses between delta202 mice heterozygous for the transgene nearly 60% were transgenic; one third of these developed progressive paralysis starting in the hindlimbs at approximately 35 days of age and died at 90 +/- 30 days of age. In affected mice proliferating-non-neuronal cells immunostained with antibodies to the GFAP, an astrocyte marker, whose number increased with age were found in the white matter of the brain, cerebellum and spinal cord, and progressive degeneration and necrosis of spinal motoneurons was observed that-may explain the paralysis. The early onset and reproducible time course of the neurological disease suggest that homozygous delta202 mice, whose proliferating astrocytes appear to damage spinal motoneurons, are a useful model to study astrocyte differentiation, function and tumorigenesis.

    Paralysis following spinal cord injury, brainstemstroke, amyotrophic lateral sclerosis and other disorders can disconnect the brain from the body, eliminating the ability to perform volitional movements. A neural interface system could restore mobility and independence for people with paralysis by translating neuronal activity directly into control signals for assistive devices. We have previously shown that people with long-standing tetraplegia can use a neural interface ...

    2004-08-01

    This study reports three cases of ulnar neuropathy after trampoline injuries in children. A chart review was performed on children who sustained an ulnar nerve injury from a trampoline accident. In all cases, surgical intervention was required. Injuries included upper-extremity fractures in two cases and an upper-extremity laceration in one case. All cases required surgical exploration with internal neurolysis and ulnar nerve transposition. Nerve grafts were used in two cases and an additional nerve transfer was used in one case. All patients had return of intrinsic hand function and sensation after surgery. Children should be followed for evolution of ulnar nerve neuropathy after upper-extremity injury with consideration for electrical studies and surgical exploration if there is no improvement after 3 months.

  12. Role of Melatonin in Traumatic Brain Injury and Spinal Cord Injury

    Full Text Available Brain and spinal cord are implicated in incidences of two of the most severe injuries of central nervous system (CNS. Traumatic brain injury (TBI is a devastating neurological deficit involving primary and secondary injury cascades. The primary and secondary mechanisms include complex consequences of activation of proinflammatory cytokines, cerebral edema, upregulation of NF-κβ, disruption of blood-brain barrier (BBB, and oxidative stress. Spinal cord injury (SCI includes primary and secondary injury cascades. Primary injury leads to secondary injury in which generation of free radicals and oxidative or nitrative damage play an important pathophysiological role. The indoleamine melatonin is a hormone secreted or synthesized by pineal gland in the brain which helps to regulate sleep and wake cycle. Melatonin has been shown to be a versatile hormone having antioxidative, antiapoptotic, neuroprotective, and anti-inflammatory properties. It has a special characteristic of crossing BBB. Melatonin has neuroprotective role in the injured part of the CNS after TBI and SCI. A number of studies have successfully shown its therapeutic value as a neuroprotective agent in the treatment of neurodegenerative diseases. Here in this review we have compiled the literature supporting consequences of CNS injuries, TBI and SCI, and the protective role of melatonin in it.

    Full Text Available We report on a female patient who underwent an arthroscopy of the right knee and was given a continuous femoral nerve block catheter. The postoperative course was initially unremarkable, but when postoperative mobilisation was commenced, 18 hours after removal of the catheter, the patient noticed paralysis and hypaesthesia. Examination confirmed the diagnosis of femoral nerve dysfunction. Colour duplex sonography of the femoral artery and computed tomography of the lumbar spine and pelvis yielded no pathological findings. Overnight the neurological deficits decreased without therapy and were finally no longer detectable. We speculate that during the administration of the local anaesthetic a depot formed, localised in the medial femoral intermuscular septa, which was leaked after first mobilisation. To our knowledge no similar case has been published up to now. We conclude that patients who are treated with a nerve block should be informed and physician should be aware that delayed neurological deficits are possible.

    Abstract Bilateral diaphragmatic paralysis (BDP) manifests as respiratory muscle weakness, and its association with critical illness polyneuropathy (CIP) was rarely reported. Here, we present a patient with BDP related to CIP, who successfully avoided tracheostomy after diagnosis and management. A 71-year-old male presented with acute respiratory failure after sepsis adequately treated. Repeated intubation occurred because of carbon dioxide retention after each extubation. After eliminating possible factors, septic shock-induced respiratory muscle weakness was suspected. Physical examination, a nerve conduction study, and chest ultrasound confirmed our impression. Pulmonary rehabilitation and reconditioning exercises were arranged, and the patient was discharged with a diagnosis of BDP. The diagnosis of BDP is usually delayed, and there are only sporadic reports on its association with polyneuropathy, especially in patients with preserved limb muscle function. Therefore, when physicians encounter patients that are difficult to wean from mechanical ventilation, CIP associated with BDP should be considered in the differential diagnosis. PMID:26252301

    The range of injuries sustained at an ice-rink and presented to an Accident Service department is described. A total of 203 patients with 222 injuries presented themselves during a 2-month period. There were 103 noteworthy injuries, including 61 fractures, 2 dislocations and 2 severed tendons, but the commonest injuries were wounds, sprains and bruises. Beginners appear to be more prone to injury than experienced skaters. In addition to using well-fitting skate-boots to protect the ankle, some injuries could be avoided by wearing elbow and knee pads, and a thick pair of gloves. The number of injuries compared with the total number of skaters was small but produced a noteworthy increase in the workload of the Accident Service.

    Road traffic injury surveillance involves methodological difficulties due, among other reasons, to the lack of consensus criteria for case definition. Police records have usually been the main source of information for monitoring traffic injuries, while health system data has hardly been used. Police records usually include comprehensive information on the characteristics of the crash, but often underreport injury cases and do not collect reliable information on the severity of injuries. However, statistics on severe traffic injuries have been based almost exclusively on police data. The aim of this paper is to propose criteria based on medical records to define: a) "Hospital discharge for traffic injuries", b) "Person with severe traffic injury", and c) "Death from traffic injuries" in order to homogenize the use of these sources.

    Spinal compression injury targeted to the neonatal upper lumbar spinal cord, the region of highest hindlimb locomotor rhythmogenicity, leads to an initial paralysis of the hindlimbs. Behavioural recovery is evident within a few days and approaches normal function within about 3 weeks. Fictive locomotion in the isolated injured spinal cord cannot be elicited by a neurochemical cocktail containing NMDA, dopamine and serotonin 1 day post-injury, but can 3 days post-injury as readily as in the uninjured spinal cord. Low frequency coordinated rhythmic activity can be elicited in the isolated uninjured spinal cord by NMDA + dopamine (without serotonin), but not in the isolated injured spinal cord. In both the injured and uninjured spinal cord, eliciting bona fide fictive locomotion requires the additional presence of serotonin. Following incomplete compression injury in the thoracic spinal cord of neonatal mice 1 day after birth (P1), we previously reported that virtually normal hindlimb locomotor function is recovered within about 3 weeks despite substantial permanent thoracic tissue loss. Here, we asked whether similar recovery occurs following lumbar injury that impacts more directly on the locomotor central pattern generator (CPG). As in thoracic injuries, lumbar injuries caused about 90% neuronal loss at the injury site and increased serotonergic innervation below the injury. Motor recovery was slower after lumbar than thoracic injury, but virtually normal function was attained by P25 in both cases. Locomotor CPG status was tested by eliciting fictive locomotion in isolated spinal cords using a widely used neurochemical cocktail (NMDA, dopamine, serotonin). No fictive locomotion could be elicited 1 day post-injury, but could within 3 days post-injury as readily as in age-matched uninjured control spinal cords. Burst patterning and coordination were largely similar in injured and control spinal cords but there were differences. Notably, in both groups there

    Surveillance for cases of acute flaccid paralysis (AFP) is a key strategy adopted for the eradication of polio. Detection of poliovirus circulation is often predicated on the ability to identify AFP cases and test their stool specimens for poliovirus infection in a timely manner. The Village Polio Volunteers (VPV) program was established in 2013 in a bid to strengthen polio eradication activities in Somalia, including AFP surveillance, given the country's vulnerability to polio outbreaks. To assess the impact of the VPV program on AFP surveillance, we determined case counts, case-reporting sources, and non-polio AFP rates in the years before and after program introduction, i.e., 2011-2016. We also compared the stool adequacy and timeliness of cases reported by VPVs to those reported by other sources. In the years following program introduction, VPVs accounted for a high proportion of AFP cases reported in Somalia. AFP case counts rose from 148 cases in 2012, the year before program introduction, to 279 cases in 2015, during which VPVs accounted for 40% of reported cases. Further, the non-polio AFP rate improved from 2.8 cases in 2012 to 4.8 cases per 100,000 persons Somalia, similar community-based programs could play a crucial role in enhancing surveillance activities in countries with limited healthcare infrastructure.

    Full Text Available Abstract Background Since their discovery, the morphology of microglia has been interpreted to mirror their function, with ramified microglia constantly surveying the micro-environment and rapidly activating when changes occur. In 1899, Franz Nissl discovered what we now recognize as a distinct microglial activation state, microglial rod cells (Stäbchenzellen, which he observed adjacent to neurons. These rod-shaped microglia are typically found in human autopsy cases of paralysis of the insane, a disease of the pre-penicillin era, and best known today from HIV-1-infected brains. Microglial rod cells have been implicated in cortical ‘synaptic stripping’ but their exact role has remained unclear. This is due at least in part to a scarcity of experimental models. Now we have noted these rod microglia after experimental diffuse brain injury in brain regions that have an associated sensory sensitivity. Here, we describe the time course, location, and surrounding architecture associated with rod microglia following experimental diffuse traumatic brain injury (TBI. Methods Rats were subjected to a moderate midline fluid percussion injury (mFPI, which resulted in transient suppression of their righting reflex (6 to 10 min. Multiple immunohistochemistry protocols targeting microglia with Iba1 and other known microglia markers were undertaken to identify the morphological activation of microglia. Additionally, labeling with Iba1 and cell markers for neurons and astrocytes identified the architecture that surrounds these rod cells. Results We identified an abundance of Iba1-positive microglia with rod morphology in the primary sensory barrel fields (S1BF. Although present for at least 4 weeks post mFPI, they developed over the first week, peaking at 7 days post-injury. In the absence of contusion, Iba1-positive microglia appear to elongate with their processes extending from the apical and basal ends. These cells then abut one another and lay adjacent

    Spinal cord injury disrupts the communication between the brain and the spinal circuits that orchestrate movement. To bypass the lesion, brain–computer interfaces1–3 have directly linked cortical activity to electrical stimulation of muscles, which have restored grasping abilities after hand paralysis1,4. Theoretically, this strategy could also restore control over leg muscle activity for walking5. However, replicating the complex sequence of individual muscle activation patterns underlying natural and adaptive locomotor movements poses formidable conceptual and technological challenges6,7. Recently, we showed in rats that epidural electrical stimulation of the lumbar spinal cord can reproduce the natural activation of synergistic muscle groups producing locomotion8–10. Here, we interfaced leg motor cortex activity with epidural electrical stimulation protocols to establish a brain–spinal interface that alleviated gait deficits after a spinal cord injury in nonhuman primates. Rhesus monkeys were implanted with an intracortical microelectrode array into the leg area of motor cortex; and a spinal cord stimulation system composed of a spatially selective epidural implant and a pulse generator with real-time triggering capabilities. We designed and implemented wireless control systems that linked online neural decoding of extension and flexion motor states with stimulation protocols promoting these movements. These systems allowed the monkeys to behave freely without any restrictions or constraining tethered electronics. After validation of the brain–spinal interface in intact monkeys, we performed a unilateral corticospinal tract lesion at the thoracic level. As early as six days post-injury and without prior training of the monkeys, the brain–spinal interface restored weight-bearing locomotion of the paralyzed leg on a treadmill and overground. The implantable components integrated in the brain–spinal interface have all been approved for investigational

    It is known that some people can, and do, sustain >1 injury over a playing season. However, there is currently little high-quality epidemiological evidence about the risk of, and relationships between, multiple and subsequent injuries. To describe the subsequent injuries sustained by Australian Football League (AFL) players over 1 season, including their most common injury diagnoses. Cohort study; Level of evidence, 3. Within-player linked injury data on all date-ordered match-loss injuries sustained by AFL players during 1 full season were obtained. The total number of injuries per player was determined, and in those with >1 injury, the Subsequent Injury Classification (SIC) model was used to code all subsequent injuries based on their Orchard Sports Injury Classification System (OSICS) codes and the dates of injury. There were 860 newly recorded injuries in 543 players; 247 players (45.5%) sustained ≥1 subsequent injuries after an earlier injury, with 317 subsequent injuries (36.9% of all injuries) recorded overall. A subsequent injury generally occurred to a different body region and was therefore superficially unrelated to an index injury. However, 32.2% of all subsequent injuries were related to a previous injury in the same season. Hamstring injuries were the most common subsequent injury. The mean time between injuries decreased with an increasing number of subsequent injuries. When relationships between injuries are taken into account, there is a high level of subsequent (and multiple) injuries leading to missed games in an elite athlete group.

    To describe the leading mechanisms of hospitalised unintentional injury in Australian Aboriginal children and identify the injury mechanisms with the largest inequalities between Aboriginal and non-Aboriginal children. We used linked hospital and mortality data to construct a whole of population birth cohort including 1,124,717 children (1,088,645 non-Aboriginal and 35,749 Aboriginal) born in the state of New South Wales (NSW), Australia, between 1 July 2000 and 31 December 2012. Injury hospitalisation rates were calculated per person years at risk for injury mechanisms coded according to the ICD10-AM classification. The leading injury mechanisms in both groups of children were falls from playground equipment. For 66 of the 69 injury mechanisms studied, Aboriginal children had a higher rate of hospitalisation compared with non-Aboriginal children. The largest relative inequalities were observed for injuries due to exposure to fire and flame, and the largest absolute inequalities for injuries due to falls from playground equipment. Aboriginal children in NSW experience a significant higher burden of unintentional injury compared with their non-Aboriginal counterparts. Implications for Public Health: We suggest the implementation of targeted injury prevention measures aimed at injury mechanism and age groups identified in this study. © 2016 The Authors.

    Full Text Available Introduction: Unilateral vocal cord paralysis (UVCP is not an uncommon finding. Several procedures are available to manage glottal insufficiency. We conducted a clinical trial to evaluate the outcome of fat injection laryngoplasty.   Materials and Methods: Liposuctioned lower abdomen fat was injected for augmentation of paralyzed vocal cord in 20 patients with UVCP. Autologous fat was harvested with an 18G needle and a 20-ml disposable syringe using a liposuction technique. Clinical follow-up after the injection was carried out from 1 to 6–21 months   Results: Voice and glottal protective function were significantly improved after the surgery. Vocal elements were immediately improved after the surgery, and after 1 year of follow-up. Conclusion:  Fat injection laryngoplasty by liposuction is simple, safe, effective and has a low cost for patients with UVCP with aspiration and breathy voice dysphonia.

    Midface reanimation in patients with chronic facial paralysis is not always possible with an ipsilateral or contralateral facial nerve innervating a free neuromuscular tissue transfer. Alternate use of nonfacial nerves is occasionally indicated but may potentially result in inadvertent motions. The goal of this study was to objectively review videos of patients who underwent one-stage reanimation with a gracilis muscle transfer innervated by the masseteric nerve for (1) inadvertent motion during eating, (2) characterization of masticatory patterns, and (3) social hindrance perceived by the patients during meals. Between the years 2009 and 2012, 18 patients underwent midfacial reanimation with partial gracilis muscle transfer coapted to the masseter nerve for treatment of midfacial paralysis. Sixteen patients were videotaped in detail while eating. Involuntary midface movement on the reconstructed side and mastication patterns were assessed. In addition, 16 patients were surveyed as to whether involuntary motion constituted a problem in their daily lives. All 16 patients videotaped during mastication demonstrated involuntary motion on the reconstructed side while eating. Several unique masticatory patterns were noted as well. Only one of the 16 patients reported involuntary motion as a minor disturbance in daily life during meals. All patients with chronic facial paralysis who plan to undergo midface reanimation with a free tissue transfer innervated by the ipsilateral masseter nerve should be told that they would universally have involuntary animation during mastication. Most patients do not consider this a major drawback in their daily lives. Therapeutic, IV.

    In New Zealand (NZ), 20% of adults report a disability, of which one-third is caused by injury. No prospective epidemiological studies of predictors of disability following all-cause injury among New Zealanders have been undertaken. Internationally, studies have focused on a limited range of predictors or specific injuries. Although these studies provide useful insights, applicability to NZ is limited given the importance of NZ's unique macro-social factors, such as NZ's no-fault accident compensation and rehabilitation scheme, the Accident Compensation Corporation (ACC). (1) To quantitatively determine the injury, rehabilitation, personal, social and economic factors leading to disability outcomes following injury in NZ. (2) To qualitatively explore experiences and perceptions of injury-related outcomes in face-to-face interviews with 15 Māori and 15 other New Zealanders, 6 and 12 months after injury. Four geographical regions within NZ. Prospective cohort study with telephone interviews 1, 4 and 12 months after injury. 2500 people (including 460 Māori), aged 18-64 years, randomly selected from ACC's entitlement claims register (people likely to be off work for at least 1 week or equivalent). Telephone interviews, electronic hospital and ACC injury data. Exposures include demographic, social, economic, work-related, health status, participation and/or environmental factors. Primary: disability (including WHODAS II) and health-related quality of life (including EQ-5D). Secondary: participation (paid and unpaid activities), life satisfaction and costs. Separate regression models will be developed for each of the outcomes. Repeated measures outcomes will be modelled using general estimating equation models and generalised linear mixed models.

    Although injuries sustained during ice skating have been reported to be more serious than other forms of skating, the potential injury risks are often underestimated by skating participants. The purpose of this study was to give a descriptive overview of injury patterns occurring during ice skating. Special emphasis was put on injury severity by using a standardised injury classification system. Over a six month period, all patients treated with ice-skating-related injuries at Europe's largest hospital were included. Patient demographics were collected and all injuries categorised according to the Abbreviated Injury Scale (AIS) 2005. A descriptive statistic and logistic regression analysis was performed. Three hundred and forty-one patients (134 M, 207 F) were included in this study. Statistical analysis revealed that age had a significant influence on injury severity. People > 50 years had a higher risk of sustaining a more severe injury according to the AIS compared with younger skaters. Furthermore, the risk of head injury was significantly lower for people aged between 18 and 50 years than for people  50 years than for people aged between 18 and 50 years (p = 0.04). The severity of ice-skating injuries is associated with the patient's age, showing more severe injuries in older patients. Awareness should be raised among the public and physicians about the risks associated with this activity in order to promote further educational interventions and the use of protective gear.

    Background Cases of polio in India declined after the implementation of the polio eradication programme especially in these recent years. The programme includes surveillance of acute flaccid paralysis (AFP) to detect and diagnose cases of polio at early stage. Under this surveillance, over 40,000 cases of AFP are reported annually since 2007 regardless of the number of actual polio cases. Yet, not much is known about these children. We conducted a qualitative research to explore care and support for children with AFP after their diagnosis. Methods The research was conducted in a district of western Uttar Pradesh classified as high-risk area for polio. In-depth interviews with parents of children with polio (17), with non-polio AFP (9), healthcare providers (40), and key informants from community including international and government officers, religious leaders, community leaders, journalists, and academics (21) were performed. Results Minimal medicine and attention were provided at government hospitals. Therefore, most parents preferred private-practice doctors for their children with AFP. Many were visited at homes to have stool samples collected by authorities. Some were visited repetitively following the sample collection, but had difficulty in understanding the reasons for these visits that pertained no treatment. Financial burden was a common concern among all families. Many parents expressed resentment for their children's disease, notably have been affected despite receiving multiple doses of polio vaccine. Both parents and healthcare providers lacked information and knowledge, furthermore poverty minimised the access to available healthcare services. Medicines, education, and transportation means were identified as foremost needs for children with AFP and residual paralysis. Conclusions Despite the high number of children diagnosed with AFP as part of the global polio eradication programme, we found they were not provided with sufficient medical support

    Softball is enjoyed by millions of female and male athletes of all ages and competitive levels. Windmill pitchers are at risk for developing overuse injuries in the throwing arm. Improper mechanics and lack of pitch counts may increase the risk for developing a pitching-related injury. Softball-related overuse injuries include proximal biceps tendinitis, upper extremity stress fractures, and ulnar neuritis. Acute injuries commonly occur in the lower extremity and include both fractures and ligamentous injuries. Sliding injuries account for a significant number of these lower extremity injuries. The addition of breakaway bases and mandatory use of protective headgear by defensive players may decrease acute injuries commonly seen in softball. Off-season programs should stress proper throwing and sliding mechanics, core conditioning, and a lower extremity neuromuscular education program.

    2012-11-01

    Masseteric and hypoglossal nerve transfers are reliable alternatives for reanimating short-term facial paralysis. To date, few studies exist in the literature comparing these techniques. This work presents a quantitative comparison of masseter-facial transposition versus hemihypoglossal facial transposition with a nerve graft using the Facial Clima system. Forty-six patients with complete unilateral facial paralysis underwent reanimation with either hemihypoglossal transposition with a nerve graft (group I, n = 25) or direct masseteric-facial coaptation (group II, n = 21). Commissural displacement and commissural contraction velocity were measured using the Facial Clima system. Postoperative intragroup commissural displacement and commissural contraction velocity means of the reanimated versus the normal side were first compared using a paired sample t test. Then, mean percentages of recovery of both parameters were compared between the groups using an independent sample t test. Onset of movement was also compared between the groups. Significant differences of mean commissural displacement and commissural contraction velocity between the reanimated side and the normal side were observed in group I but not in group II. Mean percentage of recovery of both parameters did not differ between the groups. Patients in group II showed a significantly faster onset of movement compared with those in group I (62 ± 4.6 days versus 136 ± 7.4 days, p = 0.013). Reanimation of short-term facial paralysis can be satisfactorily addressed by means of either hemihypoglossal transposition with a nerve graft or direct masseteric-facial coaptation. However, with the latter, better symmetry and a faster onset of movement are observed. In addition, masseteric nerve transfer avoids morbidity from nerve graft harvesting. Therapeutic, III.

    Traumatic brain injury (TBI) from blast produces a number of conundrums. This review focuses on five fundamental questions including: (1) What are the physical correlates for blast TBI in humans? (2) Why is there limited evidence of traditional pulmonary injury from blast in current military field epidemiology? (3) What are the primary blast brain injury mechanisms in humans? (4) If TBI can present with clinical symptoms similar to those of Post-Traumatic Stress Disorder (PTSD), how do we clinically differentiate blast TBI from PTSD and other psychiatric conditions? (5) How do we scale experimental animal models to human response? The preponderance of the evidence from a combination of clinical practice and experimental models suggests that blast TBI from direct blast exposure occurs on the modern battlefield. Progress has been made in establishing injury risk functions in terms of blast overpressure time histories, and there is strong experimental evidence in animal models that mild brain injuries occur at blast intensities that are similar to the pulmonary injury threshold. Enhanced thoracic protection from ballistic protective body armor likely plays a role in the occurrence of blast TBI by preventing lung injuries at blast intensities that could cause TBI. Principal areas of uncertainty include the need for a more comprehensive injury assessment for mild blast injuries in humans, an improved understanding of blast TBI pathophysiology of blast TBI in animal models and humans, the relationship between clinical manifestations of PTSD and mild TBI from blunt or blast trauma including possible synergistic effects, and scaling between animals models and human exposure to blasts in wartime and terrorist attacks. Experimental methodologies, including location of the animal model relative to the shock or blast source, should be carefully designed to provide a realistic blast experiment with conditions comparable to blasts on humans. If traditional blast scaling is

    The civil war in Syria including the deliberate targeting of healthcare services resulted in a complex humanitarian emergency, seriously affecting children's health. The objectives of this study are to document diagnoses and disease categories in Northern Syrian children after four years of conflict, and to document infectious diseases and injuries in this vulnerable population. In a prospective cross-sectional observational sample study conducted in May 2015, healthcare workers registered demographics, comorbidities, and diagnoses (categorised according to the International Classification of Diseases version 10) in children visited at home and in internally displaced persons camps in four Syrian governorates. Of 1080 filled-out records, 1002 were included. Children originated from Aleppo (41%), Idleb (36%), Hamah (15%) and Lattakia (8%). Median age was 6 years (0-15; IQR 3-11), 61% were boys, 40% were younger than 5 years old. Children suffered from respiratory (29%), neurological (19%), digestive (17%), eye (5%) and skin (5%) diseases. Clinical malnutrition was seen in 4%, accidental injury in 3%, intentional injury in 1%, and mental disorders in 2%. Overall, 64% had features of infectious diseases (OR 0.635; CI 0.605-0.665). Most common comorbidities were chronic respiratory diseases (14, malnutrition (5%), acute flaccid paralysis (5%), and epilepsy (4%). Logistic regression analysis indicated that the risk for children to have communicable diseases was higher in Aleppo than in Idleb (OR 1.7; CI 1.2-2.3), Hamah (OR 4.9; CI 3.3-7.5), or Lattakia (OR 5.5; CI 3.3-9.3). Children in Aleppo and Lattakia were more at risk to be injured than in Idleb (OR 5.6; CI 2.1-14.3), or in Hamah (OR 5.9; CI 1.4-25.6), but more often from intentional violence in Lattakia. Mental problems were more prominent in Hamah. Four years far in the conflict, 64% of the studied children in four Northern Syrian governorates suffer from infections, mostly from respiratory, neurological and

    Respiratory compromise due to phrenic motor neuron loss is a debilitating consequence of a large proportion of human traumatic spinal cord injury (SCI) cases (1) and is the ultimate cause of death in patients with the motor neuron disorder, amyotrophic laterals sclerosis (ALS) (2). ALS is a devastating neurological disorder that is characterized by relatively rapid degeneration of upper and lower motor neurons. Patients ultimately succumb to the disease on average 2-5 years following diagnosis because of respiratory paralysis due to loss of phrenic motor neuron innnervation of the diaphragm (3). The vast majority of cases are sporadic, while 10% are of the familial form. Approximately twenty percent of familial cases are linked to various point mutations in the Cu/Zn superoxide dismutase 1 (SOD1) gene on chromosome 21 (4). Transgenic mice (4,5) and rats (6) carrying mutant human SOD1 genes ((G93A, G37R, G86R, G85R)) have been generated, and, despite the existence of other animal models of motor neuron loss, are currently the most highly used models of the disease. Spinal cord injury (SCI) is a heterogeneous set of conditions resulting from physical trauma to the spinal cord, with functional outcome varying according to the type, location and severity of the injury (7). Nevertheless, approximately half of human SCI cases affect cervical regions, resulting in debilitating respiratory dysfunction due to phrenic motor neuron loss and injury to descending bulbospinal respiratory axons (1). A number of animal models of SCI have been developed, with the most commonly used and clinically-relevant being the contusion (8). Transplantation of various classes of neural precursor cells (NPCs) is a promising therapeutic strategy for treatment of traumatic CNS injuries and neurodegeneration, including ALS and SCI, because of the ability to replace lost or dysfunctional CNS cell types, provide neuroprotection, and deliver gene factors of interest (9). Animal models of both ALS and

    Trampolines for home use have become common in Finland during the past ten years, being especially favored by children. Trampoline jumping is beneficial and constructive physical exercise, but poses a significant risk for injuries. The most common injuries include sprains and strains. During summertime, trampoline injuries account for as many as 13% of children's accidents requiring hospital care. Fractures are by far the most common trampoline injuries requiring hospital care. Injuries can be prevented by using safety nets. Only one child at a time is allowed to jump on the trampoline.

    Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology. Copyright © 2012. Published by Elsevier Ireland Ltd.

    Full Text Available Among the viruses infecting honey bees, chronic bee paralysis virus (CBPV is known to induce significant losses in honey bee colonies. CBPV is an unclassified polymorphic single stranded RNA virus. Using RT-PCR, the virus infections in honey bees can be detected in a rapid and accurate manner. Bee samples were collected from 23 provinces of Iran, between July-September 2011 and 2012. A total of 160 apiaries were sampled and submitted for virus screening. RNA extraction and RT-PCR were performed with QIAGEN kits. The primers lead to a fragment of 315 bp. The PCR products were electrophoresed in a 1.2 % agarose gel. Following the RT-PCR reaction with the specific primers, out of the 160 apiaries examined, 12 (7.5 % were infected with CBPV. This is the first study of CBPV detection in Iranian apiaries. We identified CBPV in the collected samples from different geographic regions of Iran.

    Aim: To assess the accuracy of the trauma team leader's clinical suspicion of injury in patients who have undergone whole-body computed tomography (WBCT) for suspected polytrauma, and to assess the frequency of unsuspected injuries and specific patterns of injury at WBCT. Materials and methods: Requests for patients who underwent WBCT for suspected polytrauma from April 2011 to March 2014 were reviewed and each body area that was clinically suspected to be injured was recorded. Body areas were divided into the following groups based on anatomical regions covered in each segment of the WBCT examination: head (including facial bones); neck (including cervical spine); chest (including thoracic spine); and abdomen/pelvis (including lumbar spine). The formal radiology report for each study was reviewed and injuries found at CT were grouped into the same body areas. For each patient, the number of clinically suspected injured areas was compared to the number of confirmed injured areas at WBCT. Results: Five hundred and eighty-eight patients were included in the study. Thirty-two percent (186/588) had a normal scan. Ninety-three percent (546/588) had fewer injured body areas at WBCT than suspected. Four percent (27/588) had the equivalent number of injured areas at WBCT as suspected. Three percent (15/588) had more injured areas at WBCT than suspected. Fifty percent (263/527) with clinically suspected chest injuries were confirmed to have chest injuries at WBCT. This was lower for other areas: abdomen/pelvis 31% (165/535); head 29% (155/533); neck 13% (66/513). Four percent of (24/588) patients had unsuspected injuries found at WBCT. Seventy-five percent (18/24) of unsuspected injuries were considered as serious, where failure to treat would have the potential for significant morbidity. Most of these patients had severe injuries to other body areas that were correctly suspected. Of the 165 with abdominal/pelvic region injuries, there were associated injuries in the

    Full Text Available Abstract Background The association between fire-setting behavior and psychiatric or medical disorders remains poorly understood. Although a link between fire-setting behavior and various organic brain disorders has been established, associations between fire setting and focal brain lesions have not yet been reported. Here, we describe the case of a 24-year-old first time arsonist who suffered Todd’s paralysis prior to the onset of a bizarre and random fire-setting behavior. Case presentation A case of a 24-year-old man with a sudden onset of a bizarre and random fire-setting behavior is reported. The man, who had been arrested on felony arson charges, complained of difficulties concentrating and of recent memory disturbances with leg weakness. A video-EEG recording demonstrated a close relationship between the focal motor impairment and a clear-cut epileptic ictal discharge involving the bilateral motor cortical areas. The SPECT result was statistically analyzed by comparing with standard SPECT images obtained from our institute (easy Z-score imaging system; eZIS. eZIS revealed hypoperfusion in cingulate cortex, basal ganglia and hyperperfusion in frontal cortex,. A neuropsychological test battery revealed lower than normal scores for executive function, attention, and memory, consistent with frontal lobe dysfunction. Conclusion The fire-setting behavior and Todd’s paralysis, together with an unremarkable performance on tests measuring executive function fifteen months prior, suggested a causal relationship between this organic brain lesion and the fire-setting behavior. The case describes a rare and as yet unreported association between random, impulse-driven fire-setting behavior and damage to the brain and suggests a disconnection of frontal lobe structures as a possible pathogenic mechanism.

    Full Text Available Background. The study of the influence of various factors on the course of recovery of neurological disorders in children with spinal cord injuries is an important and relevant problem. The main causes of thoracic and lumbar injuries of the spine in children are road accidents and catatraumas. Anatomical and physiological features of the spine and spinal cord in children have a significant influence on the nature of spinal cord injury, clinical manifestations of the injury, and method of treatment. The degree of spinal canal deformity at the level of the damaged segment is directly proportional to the severity of the neurological disorder. The time between injury to when surgery is performed will strongly influence the nature and course of recovery of motor functions. Aim. To assess the influence of different factors in pediatric patients with complicated injuries of the spine at the thoracic and thoracolumbar levels on the recovery of neurological disorders. Materials and methods. The analysis of results of the surgical treatment of 36 children (24 boys and 12 girls aged 3-17 years with damage to the spine and spinal cord in the thoracic spine and thoracolumbar junction, accompanied with neurological deficit in the form of central or peripheral paresis and paralysis, was performed. All patients underwent surgical intervention depending on the type and extent of damage. Clinical methods (i.e., detailed neurological examination as well as X-ray, CT, and MRI were used as diagnostic methods. Results. The study revealed that the most severe damage concerning neurological disorders in children with spinal cord injury occurs in the thoracic spine. The extent of neurological changes depends not only on the level of damage to the spinal column but also on the magnitude of spinal canal stenosis. Surgery performed in the first hours of the injury leads to a more rapid and full recovery of the neurological deficit. Conclusion. Therefore, this study found

    A series of complications caused by enteroviruses, including meningitis, encephalitis, acute flaccid paralysis, acute cardiopulmonary failure, respiratory infection, and myocardial injury have been reported in hand, foot and mouth disease/herpangina (HFMD/HA). However, the complication of diarrhoea caused by enteroviruses has been neglected, and a summary of its clinical features and impact on HFMD/HA is unavailable. We included inpatients with HFMD/HA admitted to the Paediatric Department of Zhujiang Hospital during 2009-2012. We summarised and compared clinical data for cases with and without diarrhoea, and determined enterovirus serotypes by reverse transcriptase polymerase chain reaction and genotyping based on a partial-length fragment of viral protein 1 or the 5'-untranslated region. There were 804 inpatients with HFMD/HA and 28 (3.5%) presented with diarrhoea. Gastrointestinal symptoms were mild in most cases of diarrhoea (82.1%), with high prevalence of no dehydration (82.1%), short duration of diarrhoea (78.6%) and watery stools (75.0%). The prevalence of multi-organ dysfunction syndrome (10.7 vs 0.40%) (p = 0.001), hepatic injury (14.3 vs 3.4%) (p = 0.019), myocardial injury (21.4 vs 6.1%) (p = 0.002) and convulsion (21.4 vs 7.2%) (p = 0.016) was significantly higher in the diarrhoea than no diarrhoea group. There was no significant difference between the two groups regarding prevalence of death, altered consciousness, paralysis, central nervous system involvement, or acute respiratory infection. Most patients with diarrhoea caused by enteroviruses circulating in Guangdong Province in 2009-2012 had mild or moderate gastrointestinal symptoms. Although enterovirus-related diarrhoea caused additional multi-organ dysfunction syndrome, hepatic injury and myocardial injury in children with HFMD/HA, timely intervention efficiently reduced disease severity and improved outcome.

    Neurofibromatosis is generally classified into types I and II: the latter may be life-threatening when the acoustic nerve tumor becomes enlarged. The author reports on a patient with bilateral acoustic nerve tumors, as well as large tumors at the neck and sacral regions, who developed facial nerve paralysis following surgery in which a gamma knife was used. The patient, a 30-year-old woman with no family history of neurofibromatosis, had a prominent neurofibroma at the pharyngeal region surgically removed when she was about 23. The procedure left her with dysfunctions of the vocal cords and lingual movements. At the age of 30 (March 2001), a tumor originating at S1 of the sacral nerve plexus was removed, which caused her leg movements to be restricted. Later, an acoustic nerve tumor was found to have enlarged; and in July 2001, the left acoustic nerve tumor was extirpated by using a gamma knife. Starting in early 2002, her left facial movements appeared to be compromised but during the follow-up observation period, she regained the movements. Patients with neurofibromatosis are often plagued by the development of multiple tumors and surgical sequelae. One is reminded that it is necessary to plan treatment with sufficient consideration given to quality of life (QOL) (including the problem of an acoustic nerve tumor that may develop in future) as well as individual patients wishes.

    Full Text Available OBJECTIVE: to describe and to analyze the experience from families of children with cerebral paralysis living under circumstances of social vulnerability. METHOD: six resident families in area with this characteristic were interviewed. It was opted to use the Symbolic Interactionism as theoretic reference and the Thematic Content Analysis of Bardin as analysis method for the data. RESULT: the experience of such families is represented in the subjects: Reorganizing the Life, with the categories "Discovering the way" and "Accommodating the routine", and Stopping a Constant Fight with the categories: "Primary Carer being overcharged", "Coexisting with the preconception", "Having locomotion difficulty" and "Living with financial difficulties". CONCLUSION: the social vulnerability influences how the family bears the chronic condition. Professionals and strategies of public health are a power to minimize impacts including those related to the family budget, but they have not been effective. They need to be sensitized to become supporting resources, to offer and to guide the access to the support networks and to spur the social service in action when necessary. This study adds knowledge to the already existing by pointing out peculiarities of the family experience in situations regarding two variables of difficult handling: chronicity and social vulnerability, evidencing the role of the professional in search of the solution for the confrontation of demands and sufferings together with the family.

    Botulinum toxin A (BTX)-induced muscle paralysis results in pronounced bone degradation with substantial bone loss. We hypothesized that whole-body vibration (WBV) and insulin-like growth factor-I (IGF-I) treatment can counteract paralysis-induced bone degradation following BTX injections by activation of the protein kinase B (Akt) signaling pathway. Female C57BL/6 mice (n = 60, 16 weeks) were assigned into six groups (n = 10 each): SHAM, BTX, BTX+WBV, BTX+IGF-I, BTX+WBV+IGF-I, and a baseline group, which was killed at the beginning of the study. Mice received a BTX (1.0 U/0.1 mL) or saline (SHAM) injection in the right hind limb. The BTX+IGF-I and BTX+WBV+IGF-I groups obtained daily subcutaneous injections of human IGF-I (1 μg/day). The BTX+WBV and BTX+WBV+IGF-I groups underwent WBV (25 Hz, 2.1 g, 0.83 mm) for 30 min/day, 5 days/week for 4 weeks. Femora were scanned by pQCT, and mechanical properties were determined. On tibial sections TRAP staining, static histomorphometry, and immunohistochemical staining against Akt, phospho-Akt, IGF-IR (IGF-I receptor), and phospho-IGF-IR were conducted. BTX injection decreased trabecular and cortical bone mineral density. The WBV and WBV+IGF-I groups showed no difference in trabecular bone mineral density compared to the SHAM group. The phospho-IGF-IR and phospho-Akt stainings were not differentially altered in the injected hind limbs between groups. We found that high-frequency, low-magnitude WBV can counteract paralysis-induced bone loss following BTX injections, while we could not detect any effect of treatment with IGF-I.

    Communication is a serious problem for patients with ventilator-dependent tetraplegia. A 73-year-old man was presented at the emergency room in cardiopulmonary arrest after falling from a height of 2 m. After successful resuscitation, fractures of the cervical spine and cervical spinal cord injury were found. Due to paralysis of the respiratory muscles, a mechanical ventilator with a tracheostomy tube was required. First, a cuffed tracheostomy tube and a speaking tracheostomy tube were inserted, and humidified oxygen was introduced via the suction line. Using these tubes, the patient could produce speech sounds, but use was limited to 10 min due to discomfort. Second, a mouthstick stylus, fixed on a mouthpiece that fits over the maxillary teeth, was used. The patient used both a communication board and a touch screen device with this mouthstick stylus. The speaking tracheostomy tube and mouthstick stylus greatly improved his ability to communicate.

    Background Despite overuse injuries being previously described as the most frequent in ballet, there are no studies on professional dancers providing the specific clinical diagnoses or type of injury based on the discipline. Hypothesis Overuse injuries are the most frequent injuries in ballet, with differences in the type and frequency of injuries based on discipline. Study Design Cross-sectional study; Level of evidence, 3. Methods This was a descriptive cross-sectional study performed between January 1, 2005, and October 10, 2010, on injuries occurring in professional dancers from leading Spanish dance companies who practiced disciplines such as classical, neoclassical, contemporary, and Spanish ballet. Data, including type of injury, were obtained from specialized medical services at the Trauma Service, Fremap, Madrid, Spain. Results A total of 486 injuries were evaluated, a significant number of which were overuse disorders (P ballet (82.60%). Injuries were more frequent among female dancers (75.90%) and classical ballet (83.60%). A statistically significant prevalence of patellofemoral pain syndrome was found in the classical discipline (P = .007). Injuries of the adductor muscles of the thigh (P = .001) and of the low back facet (P = .02) in the Spanish ballet discipline and lateral snapping hip (P = .02) in classical and Spanish ballet disciplines were significant. Conclusion Overuse injuries were the most frequent injuries among the professional dancers included in this study. The prevalence of injuries was greater for the most technically demanding discipline (classical ballet) as well as for women. Patellofemoral pain syndrome was the most prevalent overuse injury, followed by Achilles tendinopathy, patellar tendinopathy, and mechanical low back pain. Clinical Relevance Specific clinical diagnoses and injury-based differences between the disciplines are a key factor in ballet. PMID:26665100

    The objective of the study is to examine injury epidemiology and risk factors for injury in CrossFit athletes. A survey was administered to athletes at four owner-operated facilities in South Florida. Respondents reported number, location of injury, and training exposure from the preceding six months and answered questions regarding potential risk factors for injury. Fifty out of 191 athletes sustained 62 injuries during CrossFit participation in the preceding six months. The most frequently injured locations were the shoulder, knee, and lower back. Injury incidence was 2.3/1000 athlete training hours. Competitors were more likely to be injured (40% v 19%, p = 0.002) and had greater weekly athlete training hours (7.3 ± 7.0 v 4.9 ± 2.9, p CrossFit and location of injuries were similar to those previously reported. Injury incidence was similar to related sports, including gymnastics and powerlifting. While being a competitor was related to injury, increased exposure and length of participation in CrossFit likely underlied this association. Specifically, increased exposure to training in the form of greater weekly athlete training hours and weekly participations may contribute to injury. Increased height and body mass were also related to injury which is likely reflective of increased load utilized during training. Further research is warranted to determine if biomechanical factors associated with greater height and ability to lift greater loads are modifiable factors that can be adapted to reduce the increase risk of injury during CrossFit.

    The aim of this study was to evaluate long-term efficacy of an ergonomics program that included patient-handling devices in six long-term care facilities (LTC) and one chronic care hospital (CCH). Patient handling is recognized as a major source of musculoskeletal disorders (MSDs) among nursing personnel, and several studies have demonstrated effectiveness of patient-handling devices in reducing those MSDs. However, most studies have been conducted in a single facility, for a short period, and/or without a comprehensive ergonomics program. Patient-handling devices along with a comprehensive ergonomics program was implemented in six LTC facilities and one CCH. Pre- and postintervention injury data were collected for 38.9 months (range = 29 to 54 months) and 51.2 months (range = 36 to 60 months), respectively. Postintervention patient-handling injuries decreased by 59.8% (rate ratio [RR] = 0.36, 95% confidence interval [CI] [0.28, 0.49], p nursing staff were fairly low. A vast majority of patients found the devices comfortable and safe. Longer transfer times with the use of devices was not an issue. Implementation of patient-handling devices along with a comprehensive program can be effective in reducing MSDs among nursing personnel. Strategies to expand usage of patient-handling devices in most health care settings should be explored.

    The trauma registry network constitutes an essential database in every injury prevention system. In order to rationally estimate the extent of injury in general, and injuries from traffic accidents in particular, the trauma registry systems should contain the most comprehensive and broad database possible, in line with the operational definitions. Ideally, the base of the injury pyramid should also include mild injuries and even "near-misses". The Israeli National Trauma Registry has come a long way in the last few years. The eventual inclusion of all trauma centers in Israel will enable the establishment of a firm base for the allocation of resources by decision-makers.

    The severe Dismounted Complex Blast Injury (DCBI) is characterized by high-energy injuries to the bilateral lower extremities (usually proximal transfemoral amputations) and/or upper extremity (usually involving the non-dominant side), in addition to open pelvic injuries, genitourinary, and abdominal trauma. Initial resuscitation and multidisciplinary surgical management appear to be the keys to survival. Definitive treatment follows general principals of open wound management and includes decontamination through aggressive and frequent debridement, hemorrhage control, viable tissue preservation, and appropriate timing of wound closure. These devastating injuries are associated with paradoxically favorable survival rates, but associated injuries and higher amputation levels lead to more difficult reconstructive challenges.

    The dinoflagellate Gymnodinium catenatum produces paralyzing shellfish poisons that are consumed and accumulated by bivalves. We performed short-term feeding experiments to examine ingestion, accumulation, biotransformation, histopathology, and paralysis in the juvenile Pacific calico scallop Argopecten ventricosus that consume this dinoflagellate. Depletion of algal cells was measured in closed systems. Histopathological preparations were microscopically analyzed. Paralysis was observed and the time of recovery recorded. Accumulation and possible biotransformation of toxins were measured by HPLC analysis. Feeding activity in treated scallops showed that scallops produced pseudofeces, ingestion rates decreased at 8 h; approximately 60% of the scallops were paralyzed and melanin production and hemocyte aggregation were observed in several tissues at 15 h. HPLC analysis showed that the only toxins present in the dinoflagellates and scallops were the N-sulfo-carbamoyl toxins (C1, C2); after hydrolysis, the carbamate toxins (epimers GTX2/3) were present. C1 and C2 toxins were most common in the mantle, followed by the digestive gland and stomach-complex, adductor muscle, kidney and rectum group, and finally, gills. Toxin profiles in scallop tissue were similar to the dinoflagellate; biotransformations were not present in the scallops in this short-term feeding experiment.

    The number of dirt bike injuries in children in the United States is increasing and poses a public health problem. The purpose of our study was to identify the imaging patterns of dirt bike injuries in children and associations with morbidity and mortality. The study included 85 children (83 boys, 2 girls) dirt bike injury treated at a tertiary care pediatric hospital. Imaging studies and hospital medical records were reviewed. Outcomes were classified into the following categories: short-term disability, long-term disability or no follow-up available. Imaging studies were reviewed for head, torso, and extremity injuries. One-tailed z test for two proportions was used to determine significant differences between various proportions. Chi-square test with Yates correction was used to determine the significance of long-term disability with injury type. Long bone fractures were the most common injuries. Lower extremity fractures accounted for 79% of extremity fractures and were significantly more common than upper extremity fractures (p = 0.001). Head injuries included fractures (n = 9), brain contusion (n = 5), and meningeal hemorrhage (n = 2). Head injury was associated with long-term disability (p < 0.0001). All torso injuries were solitary. Long-term disability was associated with head injuries but not with torso or extremity injuries. Lower extremity injuries were significantly more common than upper extremity injuries. Torso solid organ injuries were uniformly solitary. Published by Elsevier Inc.

    Trampoline-related injuries in adults are uncommon. Participation in trampolining is increasing following its admission as a sport in the Olympics and the opening of local recreational trampoline centres. The aim of this study was to assess the number and outcomes of adult trampoline-related orthopaedic injuries presenting to four trauma hospitals in Victoria. A cohort study was performed for the period 2007-2013. Adult patients registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) who had sustained a trampolining related injury were included in this study. Descriptive analyses were used to describe the patient population, the injuries sustained and their in-hospital and 6-month outcomes. There was an increase in trampolining injuries from 2007 (n=3) to 2012 (n=14) and 2013 (n=18). Overall, fifty patients with a median age of 25 (range 16-66) were identified. Thirty-five patients (70%) had lower limb injuries, 20 patients (40%) had spinal injuries and one patient had an upper limb injury. Thirty-nine patients (78%) required surgery. Fractures of the tibia (n=13), ankle fractures (n=12) and cervical spine injuries (n=7) were the most common injuries; all of which required surgery. Complications included death, spinal cord injuries, compartment syndrome and open fractures. At 6 months post injury, more than half (52%) of the patients had not achieved a good recovery, 32% had some form of persistent disability, 14% did not get back to work and overall physical health for the cohort was well below population norms for the SF-12. Adult trampoline-related injuries have increased in the last few years in this cohort identified through VOTOR. Lower limb and spinal injuries are most prevalent. Public awareness and education are important to reduce the risk for people participating in this activity. Copyright © 2015 Elsevier Ltd. All rights reserved.

    "Heelys", or shoes with an integral wheel embedded into the heel, are becoming increasingly popular among children in the UK. Despite the manufacturer's claims about their safety, increasing numbers of patients are attending the emergency department with "Heely"-related injuries. To assess the number and type of "Heely"-related injuries seen in the emergency department in a busy district general hospital and to assess the number of school days lost as a result of these injuries as a secondary measure of the impact on education and lifestyle. Medical staff working in the emergency department completed proformas for all children attending the department with "Heely"-related injuries between 26 December and 26 April 2007. Data collected included age, sex, mechanism of injury, diagnosis and number of days off school as a result of the injury. 35 patients with "Heely"-related injuries of mean age 9.6 years (range 6-15) were identified during the study period. The most common mechanism of injury was a fall onto an outstretched hand (20/35, 57%). Other mechanisms of injury identified were lateral upper limb injury (7/35), traumatic lower limb injury (2/35), rotational lower limb injury (2/35), head injury (2/35) and back injury (2/35). The most common diagnosis was fracture of the distal radius (10/35), two of which had an associated distal ulna fracture. Two tibial fractures and one nasal fracture were also seen. The average number of days off school was 4.5 days (range 0-20). None of the children included in this study were using safety equipment at the time of the injury. The number of "Heely"-related injuries seen in one department over a 4-month period suggests a much higher incidence of injuries than the 46/100,000 found by the manufacturers based on Consumer Product Safety Commission data in the USA. The discrepancy is almost certainly due to the reluctance of UK children to use safety equipment and to follow the manufacturer's safety advice. Larger scale studies

    To evaluate the cost-effectiveness of routine computed tomography (CT) in individuals with unilateral vocal fold paralysis (UVFP) STUDY DESIGN: Health Economics Decision Tree Analysis METHODS: A decision tree was constructed to determine the incremental cost-effectiveness ratio (ICER) of CT imaging in UVFP patients. Univariate sensitivity analysis was utilized to calculate what the probability of having an etiology of the paralysis discovered would have to be to make CT with contrast more cost-effective than no imaging. We used two studies examining findings in UVFP patients. The decision pathways were utilizing CT neck with intravenous contrast after diagnostic laryngoscopy versus laryngoscopy alone. The probability of detecting an etiology for UVFP and associated costs were extracted to construct the decision tree. The only incorrect diagnosis was missing a mass in the no-imaging decision branch, which rendered an effectiveness of 0. The ICER of using CT was $3,306, below most acceptable willingness-to-pay (WTP) thresholds. Additionally, univariate sensitivity analysis indicated that at the WTP threshold of $30,000, obtaining CT imaging was the most cost-effective choice when the probability of having a lesion was above 1.7%. Multivariate probabilistic sensitivity analysis with Monte Carlo simulations also showed that at the WTP of $30,000, CT scanning is more cost-effective, with 99.5% certainty. Particularly in the current healthcare environment characterized by increasing consciousness of utilization defensive medicine, economic evaluations represent evidence-based findings that can be employed to facilitate appropriate decision making and enhance physician-patient communication. This economic evaluation strongly supports obtaining CT imaging in patients with newly diagnosed UVFP. 2c.

    Recommendations to prevent trampoline injuries were given since the 1970s. However, despite these educational efforts, safety recommendations seem to be ignored and the number of trampoline injuries is increasing. All children referred to our department for injuries related to trampolines over a period of 3 years were included. The patients' records were reviewed and a questionnaire was sent out in order to gain additional information. Injuries were classified as severe and mild. A total of 265 children (46% m, 54% f) with a median age of 8.2 years (range 1 to 14) were included. The injury rate was continuously growing from the year 2005 (10.6%) to 2007 (58.1%). Most of the injuries were recorded between April and September with a peak of injuries in August. Seventy-five percent of all accidents happened in the afternoon; 40% of the injuries were classified as severe, 60% as mild. Nets or equal security devices were used in 56.6%. Trampolining is associated with a significant risk for bodily harm at any age and results in severe injuries in 40% of cases. Though there may be still room for improvement in safety recommendations, all attempts over a period of more than 30 years to reduce the number of trampoline-related backyard injuries failed and the incidence is still increasing. At present, trampolines cannot be made safe for recreational activities and are of an unacceptable risk even under supervision.

    Injuries are the leading cause of death among adolescents. The current research examined a measure of adolescent injury in terms of whether it encompasses the diverse injury experiences of Australian adolescents, including high-risk and normative adolescents, and thus determine its utility as a tool for health promotion research. Grade 9 students from two Brisbane high schools (n=202, aged 13-14 years) and adolescents recruited from the Emergency Department waiting rooms of four Brisbane hospitals (n=98, aged 16-18 years) completed the Extended Adolescent Injury Checklist (E-AIC). The most common cause of injury among adolescents was a sports activity, followed by fights for all participants except school-based males, who experienced more bicycle injuries. Alcohol use was most frequently reported in association with interpersonal violence injuries. A broad variety of injuries, occurring in context of multiple risk as well as normative behaviours, were reported by adolescents in both school and ED settings, and were captured by the E-AIC.

    Full Text Available China has the largest number of managed honey bee colonies globally, but there is currently no data on viral infection in diseased A. mellifera L. colonies in China. In particular, there is a lack of data on chronic bee paralysis virus (CBPV in Chinese honey bee colonies. Consequently, the present study investigated the occurrence and frequency of several widespread honey bee viruses in diseased Chinese apiaries, and we used the reverse transcription-polymerase chain reaction (RT-PCR assay. Described was the relationship between the presence of CBPV and diseased colonies (with at least one of the following symptoms: depopulation, paralysis, dark body colorings and hairless, or a mass of dead bees on the ground surrounding the beehives. Phylogenetic analyses of CBPV were employed. The prevalence of multiple infections of honey bee viruses in diseased Chinese apiaries was 100%, and the prevalence of infections with even five and six viruses were higher than expected. The incidence of CBPV in diseased colonies was significantly higher than that in apparently healthy colonies in Chinese A. mellifera aparies, and CBPV isolates from China can be separated into Chinese-Japanese clade 1 and 2. The results indicate that beekeeping in China may be threatened by colony decline due to the high prevalence of multiple viruses with CBPV.

    Cosimo I de' Medici (1519-1574) was the first Grand Duke of Tuscany. He was one of the most important members of the Medici family. He was an excellent conqueror and a good politician. Moreover, he was able to attract and encourage artists, scientists and architects to promote Florence as the cultural capital of the Italian Renaissance. Historical chronicles report that he suffered from a stroke when he was 49 years old. Together with the acute manifestation of stroke, he displayed peculiar symptoms. He had gait disturbances and sphincter dysfunctions. His language became poor and hard to understand. His mood was very fluctuating and in the last years of his life he was a short-tempered man. In addition, he had a characteristic symptom, so-called pathological laughing and crying. The course of his disease was slow and stuttering. Taken together, these data seem to be one of the first reports of pseudobulbar paralysis. The disease of Cosimo I was probably due to a chronic cerebral vasculopathy, known as small vessels disease. We discuss this hypothesis regarding an ancient clinical case, with the support of current studies.

    Spinal Cord Injury (SCI) is a debilitating condition which causes neurological damage and can result in paralysis. SCI results in immediate mechanical damage to the spinal cord, but secondary injuries due to inflammation, oxidative damage, and activated biochemical pathways leading to apoptosis exacerbate the injury. The only currently available treatment, methylprednisolone, is controversial because there is no convincing data to support its therapeutic efficacy for SCI treatment. In the absence of an effective SCI treatment option, 17beta-estradiol has gained significant attention for its anti-oxidant, anti-inflammatory, and anti-apoptotic abilities, all events associated with secondary. Sadly, 17beta-estradiol is associated with systemic adverse effects preclude the use of free estrogen even for local administration due to short drug half-life in the body. Biodegradable nanoparticles can be used to increase half-life after local administration and to bestow sustained release. Sustained release using PEGylated biodegradable polymeric nanoparticles constructed from poly(lactic-co-glycolic acid) (PLGA) will endow a consistent, low, but effective dose to be delivered locally. This will limit systemic effects due to local administration and low dose, sustained release. PLGA was chosen because it has been used extensively for sustained release, and has a record of safety in humans. Here, we show the in vitro efficacy of PEGylated nanoparticles loaded with 17beta-estradiol for treatment of secondary SCI. We achieved a high loading efficiency and controlled release from the particles over a several day therapeutic window. The particles also show neuroprotection in two in vitro cell culture models. Both the dose and pretreatment time with nanoparticles was evaluated in an effort to translate the treatment into an animal model for further study.

    Beekeepers all across the world are suffering important losses of their colonies, and the parasitic mites Varroa destructor and Nosema sp, as well as several bee viruses, are being pointed out as the possible causes of these losses, generally associated with environmental and management factors. The objective of the present study was to evaluate the presence of seven virus species (Deformed wing virus -DWV-, Acute bee paralysis virus -ABPV-, Chronic bee paralysis virus -CBPV-, Black queen cell virus -BQCV-, Kashmir bee virus -KBV-, Israeli acute bee paralysis virus -IAPV-, and Sacbrood bee virus -SBV), as well as the prevalence of Nosema sp. and Varroa destructor, and their possible associated factors, under temperate and subtropical climate conditions in Argentinean colonies. A total of 385 colonies distributed in five Argentinean eco-regions were examined after honey harvest. The final multivariable model revealed only one variable associated with the presence of DWV and two with the presence of ABPV. The apiary random effect was significant in both cases (P=0.018; P=0.006, respectively). Colonies with a Varroa infestation rate >3% showed higher presence of DWV than colonies with <3% of Varroa infestation level (OR=1.91; 95% CI: 1.02-3.57; P<0.044). The same pattern was observed for the presence of ABPV (OR=2.23; 95% CI: 1.04-4.77; P<0.039). Also, colonies where replacement of old combs was not a common practice had higher presence of ABPV (OR=6.02; 95% CI: 1.16-31.25; P<0.033). Regardless of the location of the colonies, virus presence was strongly associated with V. destructor level. Therefore, all the factors that directly or indirectly influence the levels of mites will be also influencing the presence of the viruses. Copyright © 2017 Elsevier B.V. All rights reserved.

    Severe vocal fold lesions such as vocal fold sulcus, scars, and atrophy induce a communication disorder due to severe hoarseness, but a treatment has not been established. Basic fibroblast growth factor (bFGF) therapies by either four-time repeated local injections or regenerative surgery for vocal fold scar and sulcus have previously been reported, and favorable outcomes have been observed. In this study, we modified bFGF therapy using a single of bFGF injection, which may potentially be used in office procedures. Retrospective chart review. Five cases of vocal fold sulcus, six cases of scars, seven cases of paralysis, and 17 cases of atrophy were treated by a local injection of bFGF. The injection regimen involved injecting 50 µg of bFGF dissolved in 0.5 mL saline only once into the superficial lamina propria using a 23-gauge injection needle. Two months to 3 months after the injection, phonological outcomes were evaluated. The maximum phonation time (MPT), mean airflow rate, pitch range, speech fundamental frequency, jitter, and voice handicap index improved significantly after the bFGF injection. Furthermore, improvement in the MPT was significantly greater in patients with (in increasing order) vocal fold atrophy, scar, and paralysis. The improvement in the MPT among all patients was significantly correlated with age; the MPT improved more greatly in younger patients. Regenerative treatments by bFGF injection—even a single injection—effectively improve vocal function in vocal fold lesions. 4 © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

  16. Molybdenum cofactor deficiency causes translucent integument, male-biased lethality, and flaccid paralysis in the silkworm Bombyx mori.

    Uric acid accumulates in the epidermis of Bombyx mori larvae and renders the larval integument opaque and white. Yamamoto translucent (oya) is a novel spontaneous mutant with a translucent larval integument and unique phenotypic characteristics, such as male-biased lethality and flaccid larval paralysis. Xanthine dehydrogenase (XDH) that requires a molybdenum cofactor (MoCo) for its activity is a key enzyme for uric acid synthesis. It has been observed that injection of a bovine xanthine oxidase, which corresponds functionally to XDH and contains its own MoCo activity, changes the integuments of oya mutants from translucent to opaque and white. This finding suggests that XDH/MoCo activity might be defective in oya mutants. Our linkage analysis identified an association between the oya locus and chromosome 23. Because XDH is not linked to chromosome 23 in B. mori, MoCo appears to be defective in oya mutants. In eukaryotes, MoCo is synthesized by a conserved biosynthesis pathway governed by four loci (MOCS1, MOCS2, MOCS3, and GEPH). Through a candidate gene approach followed by sequence analysis, a 6-bp deletion was detected in an exon of the B. mori molybdenum cofactor synthesis-step 1 gene (BmMOCS1) in the oya strain. Moreover, recombination was not observed between the oya and BmMOCS1 loci. These results indicate that the BmMOCS1 locus is responsible for the oya locus. Finally, we discuss the potential cause of male-biased lethality and flaccid paralysis observed in the oya mutants. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2016-05-01

    Sports related injuries are common in children and adolescents, with a reported incidence of around one in ten children each year. Boys incur more and severer sports injuries than girls, and chance for injury is greater with contact or jumping sports. Sports injuries seen in children under 10-years of age are non-specific, including contusions, mild sprains, and extremity fractures, usually Salter fractures of the physes (growth plate) or plastic fractures. In the very young athlete, sports injury of the ligaments or muscle is rare as are spine or head injuries. With growth and adolescence, the intensity of sports involvement increases. Pre-pubertal children still have open physes that are prone to injury, both acute or due to stress from a repetitive activity. In addition to injury of the physes of the long bones, injuries to the physes of apophyses are common. Ligamentous injury is uncommon before physeal closure, but can occur. After the physes fuse, ligamentous injury is seen with patterns similar to adults. This review will include a description of sports related injuries seen in children and adolescents. We will concentrate on injuries that are specific for the growing skeleton, with a brief mention of those seen after fusion of the physes.

    Full Text Available Traumatic spinal cord injury (SCI results in partial or complete paralysis and is characterized by a loss of neurons and oligodendrocytes, axonal injury, and demyelination/dysmyelination of spared axons. Approximately 1,250,000 individuals have chronic SCI in the U.S.; therefore treatment in the chronic stages is highly clinically relevant. Human neural stem cells (hCNS-SCns were prospectively isolated based on fluorescence-activated cell sorting for a CD133(+ and CD24(-/lo population from fetal brain, grown as neurospheres, and lineage restricted to generate neurons, oligodendrocytes and astrocytes. hCNS-SCns have recently been transplanted sub-acutely following spinal cord injury and found to promote improved locomotor recovery. We tested the ability of hCNS-SCns transplanted 30 days post SCI to survive, differentiate, migrate, and promote improved locomotor recovery.hCNS-SCns were transplanted into immunodeficient NOD-scid mice 30 days post spinal cord contusion injury. hCNS-SCns transplanted mice demonstrated significantly improved locomotor recovery compared to vehicle controls using open field locomotor testing and CatWalk gait analysis. Transplanted hCNS-SCns exhibited long-term engraftment, migration, limited proliferation, and differentiation predominantly to oligodendrocytes and neurons. Astrocytic differentiation was rare and mice did not exhibit mechanical allodynia. Furthermore, differentiated hCNS-SCns integrated with the host as demonstrated by co-localization of human cytoplasm with discrete staining for the paranodal marker contactin-associated protein.The results suggest that hCNS-SCns are capable of surviving, differentiating, and promoting improved locomotor recovery when transplanted into an early chronic injury microenvironment. These data suggest that hCNS-SCns transplantation has efficacy in an early chronic SCI setting and thus expands the "window of opportunity" for intervention.

    This in-depth literature review shows that skateboarding has experienced intermittent periods of popularity, with an estimated 6-15 million skateboarders in the US currently involved at all levels of recreational play and competition. Head trauma accounts for ∼ 3.5-13.1% of all skateboarding injuries. Injury occurs most often to the upper extremity (55-63%), whereas thoracoabdominal and spine injuries account for 1.5-2.9% of all trauma and lower extremity injuries occur 17-26% of the time. Few fatal injuries (1.1%) have been reported, oftentimes resulting from traumatic head injuries incurred from collisions with motor vehicles. Although skateparks may be perceived as a safer alternative to street skateboarding, injuries still occur when the skateboarder collides with an object or falls from the board. Factors leading to trauma include fatigue and overuse, age and skill level, inadequate medical care, environmental conditions, equipment concerns, lack of fitness and training, and the detrimental behavior of the competitor. Although not all skateboarding injuries are avoidable, numerous opportunities exist to instill safety involving education, instruction, and supervision and the proper use of protective gear to reduce predisposition to trauma. Future research recommendations include a more standardized data collection system, as well as an increased focus on kinetic analysis of the sport. Legislation involving helmet laws and the increased investment in a safer environment for the skateboarder may also assist in reducing injury in this sport.

    Postoperative bowel paralysis is common after abdominal operations, including colectomy. As a result, hospitalization may be prolonged, thereby leading to increased cost. A recent randomized controlled trial showed that the consumption of regular black coffee after colectomy is associated with a significantly faster resumption of intestinal motility. The mechanism by which coffee stimulates intestinal motility is unknown, but caffeine seems to be the most likely stimulating agent. Thus, the effect of caffeine on postoperative bowel activity after colon surgery will be analyzed in this trial, herein referred to as CaCo. Patients scheduled for elective laparoscopic colectomy or upper rectum resection are eligible to participate in this double-blinded, placebo-controlled, randomized trial. Patients fulfilling all inclusion criteria will be allocated after the surgical procedure to one of three treatment arms: 100 mg caffeine, 200 mg caffeine, or placebo (corn starch). Patients will take the capsules containing the study medication three times daily with a meal. The primary endpoint of the study is the time to a solid bowel movement. The study treatment will be stopped after the patient produces a solid bowel movement or has taken ten capsules, whichever occurs first. To determine the colonic passage time, patients will take a capsule with radiopaque markers at breakfast for the first 3 days after surgery. On the fourth day, the location of the markers will be determined with an abdominal X-ray scan. Further secondary objectives are the postoperative morbidity and mortality, well-being, sleeping behavior, and length of hospital stay. The study size was calculated to be 180 patients with an interim analysis occurring after 60 patients. From a previous study investigating coffee, evidence exists that caffeine might have a positive influence on the postoperative bowel activity. This double-blinded, placebo-controlled, randomized trial tries to show that caffeine will

    Objectives To establish an accurate and comprehensive injury incidence registry of all rugby union-related catastrophic events in South Africa between 2008 and 2011. An additional aim was to investigate correlates associated with these injuries. Design Prospective. Setting The South African amateur and professional rugby-playing population. Participants An estimated 529 483 Junior and 121 663 Senior rugby union (‘rugby’) players (population at risk). Outcome measures Annual average incidences of rugby-related catastrophic injuries by type (cardiac events, traumatic brain and acute spinal cord injuries (ASCIs)) and outcome (full recoveries—fatalities). Playing level (junior and senior levels), position and event (phase of play) were also assessed. Results The average annual incidence of ASCIs and Traumatic Brain Injuries combined was 2.00 per 100 000 players (95% CI 0.91 to 3.08) from 2008 to 2011. The incidence of ASCIs with permanent outcomes was significantly higher at the Senior level (4.52 per 100 000 players, 95% CI 0.74 to 8.30) than the Junior level (0.24 per 100 000 players, 95% CI 0 to 0.65) during this period. The hooker position was associated with 46% (n=12 of 26) of all permanent ASCI outcomes, the majority of which (83%) occurred during the scrum phase of play. Conclusions The incidence of rugby-related catastrophic injuries in South Africa between 2008 and 2011 is comparable to that of other countries and to most other collision sports. The higher incidence rate of permanent ASCIs at the Senior level could be related to the different law variations or characteristics (eg, less regular training) compared with the Junior level. The hooker and scrum were associated with high proportions of permanent ASCIs. The BokSmart injury prevention programme should focus efforts on these areas (Senior level, hooker and scrum) and use this study as a reference point for the evaluation of the effectiveness of the programme.

    Full Text Available Communication is a serious problem for patients with ventilator-dependent tetraplegia. A 73-year-old man was presented at the emergency room in cardiopulmonary arrest after falling from a height of 2 m. After successful resuscitation, fractures of the cervical spine and cervical spinal cord injury were found. Due to paralysis of the respiratory muscles, a mechanical ventilator with a tracheostomy tube was required. First, a cuffed tracheostomy tube and a speaking tracheostomy tube were inserted, and humidified oxygen was introduced via the suction line. Using these tubes, the patient could produce speech sounds, but use was limited to 10 min due to discomfort. Second, a mouthstick stylus, fixed on a mouthpiece that fits over the maxillary teeth, was used. The patient used both a communication board and a touch screen device with this mouthstick stylus. The speaking tracheostomy tube and mouthstick stylus greatly improved his ability to communicate.

  6. Self-injurious behavior in anorexia nervosa.

    Favaro, A; Santonastaso, P

    2000-08-01

    Recent reports have postulated the existence of two different types of self-injurious behavior: impulsive and compulsive. The aim of the present study is to analyze the dimensionality of self-injurious behavior and to study the link between self-injurious behavior and clinical features in anorexia nervosa. The study involved 236 consecutive patients with anorexia nervosa, diagnosed by DSM-IV criteria. Subjects were evaluated by means of a semistructured interview and self-reported questionnaires, such as the Eating Disorders Inventory and Hopkins Symptom Checklist. A principal component analysis was used to study the dimensionality of different types of self-injurious behavior, including purging. Our findings confirm the distinction between impulsive and compulsive self-injurious behavior. The dimensions appear to be represented as a continuum in both the anorexia nervosa diagnostic subgroups. A third distinct dimension emerged that included self-induced vomiting and laxative/diuretics abuse. Childhood sexual abuse and anxiety significantly predict the presence of impulsive self-injury, whereas obsessionality and age predict compulsive self-injury. The coexistence of a positive score on both dimensions of self-injurious behavior was the strongest predictor of treatment dropout. The present study highlights the importance of self-injurious behavior; it should be given due consideration in future outcome studies on anorexia nervosa

    Control of knee motion in small animal models is necessary to study the effect of mechanical load on the healing process. This can be especially challenging in mice, which are being increasingly used for various orthopedic reconstruction models. We explored the feasibility of botulinum toxin (Botox; Allergan, Dublin, Ireland) paralysis and a newly designed external fixator to restrict motion of the knee in mice undergoing anterior cruciate ligament (ACL) reconstruction. Nineteen C57BL/6 mice were allocated to two groups: (1) Botox group ( n  = 9) and (2) external fixator group ( n  = 10). Mice in Botox group received two different doses of Botox: 0.25 unit ( n  = 3) and 0.5 unit ( n  = 6). Injection was performed 72 hours prior to ACL reconstruction into the quadriceps, hamstring, and calf muscles of the right hind leg. Mice in external fixator group received an external fixator following ACL reconstruction. Mice were monitored for survival, tolerance, and achievement of complete knee immobilization. All mice were meant for sacrifice on day 14 postoperatively. No perceptible change in gait was observed with 0.25 unit of Botox. All mice that received 0.5 unit of Botox had complete hind limb paralysis documented by footprint analysis 2 days after injection but failed to tolerate anesthesia and were euthanized 24 hours after operation due to their critical condition. In contrast, the external fixator was well tolerated and effectively immobilized the limb. There was a single occurrence of intraoperative technical error in the external fixator group that led to euthanasia. No mechanical failure or complication was observed. Botox paralysis was not a viable option for postoperative restriction of motion and joint loading in mice. However, external fixation was an effective method for complete knee immobilization and can be used in murine models requiring postoperative control of knee loading. This study introduces a robust research tool to allow control

  8. Management of unilateral true vocal cord paralysis in children.

    2012-12-01

    Historically, information gained from the treatment of unilateral true vocal cord paralysis (UVCP) in adults was the same used to treat children. Today, there is a growing body of literature aimed specifically at the treatment of this condition in children. It is an area of growing interest as UVCP can significantly impact a child's quality of life. Children with UVCP may present with stridor, dysphonia, aspiration, feeding difficulties, or a combination of these symptoms. Diagnosis relies on laryngoscopy, but other adjuncts such as ultrasound and laryngeal electromyography may also be helpful in making the diagnosis and forming a treatment plan. In many instances, there is effective compensation by the contralateral vocal fold, making surgical intervention unnecessary. Children who cannot compensate for a unilateral defect may suffer from significant dysphonia that can affect their quality of life because their ability to be understood may be diminished. In these patients, treatment in the form of medialization or reinnervation of the affected recurrent laryngeal nerve may be warranted. UVCP is a well recognized problem in pediatric patients with disordered voice and feeding problems. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment. Improved diagnostics and a growing understanding of prognosis can help guide therapy decisions along with the goals and desires of the patient and his or her family.

  10. Israeli Acute Paralysis Virus Infection Leads to an Enhanced RNA Interference Response and Not Its Suppression in the Bumblebee Bombus terrestris

    Directory of Open Access Journals (Sweden)

    Kaat Cappelle

    2016-12-01

    Full Text Available RNA interference (RNAi is the primary antiviral defense system in insects and its importance for pollinator health is indisputable. In this work, we examined the effect of Israeli acute paralysis virus (IAPV infection on the RNAi process in the bumblebee, Bombus terrestris, and whether the presence of possible functional viral suppressors could alter the potency of the host’s immune response. For this, a two-fold approach was used. Through a functional RNAi assay, we observed an enhancement of the RNAi system after IAPV infection instead of its suppression, despite only minimal upregulation of the genes involved in RNAi. Besides, the presence of the proposed suppressor 1A and the predicted OrfX protein in IAPV could not be confirmed using high definition mass spectrometry. In parallel, when bumblebees were infected with cricket paralysis virus (CrPV, known to encode a suppressor of RNAi, no increase in RNAi efficiency was seen. For both viruses, pre-infection with the one virus lead to a decreased replication of the other virus, indicating a major effect of competition. These results are compelling in the context of Dicistroviridae in multi-virus/multi-host networks as the effect of a viral infection on the RNAi machinery may influence subsequent virus infections.

    This study investigates the frequency of injuries, in particular dental injuries, among ski jumpers and Nordic combined athletes. It also examines the level of knowledge regarding tooth protection and tooth rescue boxes in this population. Of the 465 sportswomen and sportsmen who took part in the study, 230 (62.5%) of the 368 ski jumpers and 56 (56.5%) of the 97 Nordic combined athletes had sustained an injury. In both disciplines injury was most likely among professionals. The survey participants reported injuries to the limbs (n = 216), head and lips (n = 273 and n = 253, respectively), torso or spine (n = 249), teeth (n = 246), nose (n = 229) and jaw (n = 26). Dental injuries were more common among professionals than either amateur or junior ski jumpers, whereas, among the Nordic combined athletes, juniors were most likely to sustain a dental injury. Overall, the frequency of dental injury was significantly (p = 0.019) higher among adults 12.7% (n = 234) than junior athletes 6.1% (n = 212). The level of awareness of mouthguards and tooth rescue boxes varied between countries. The high injury rate recorded in this study demonstrates that ski jumping contains a considerable risk of injury, including tooth damage. Consequently, it seems reasonable to inform skiing organisations, trainers and athletes about the potential benefits of mouthguards and tooth rescue boxes in order to reduce the risk of dental injury.

    The surveillance of acute flaccid paralysis (AFP) is a key strategy for monitoring the progress of poliomyelitis eradication and is a sensitive measure for detecting potential cases of poliomyelitis and poliovirus infection. This study was conducted to describe the characteristics of patients reported with AFP, and to evaluate the performance of the surveillance system in Kurdistan province, western Iran, using indicators recommended by the World Health Organization (WHO). This observational study was conducted from January 2000 to December 2010 at the Kurdistan Center for Disease Control and the Department of Pediatrics. All children who fulfilled the WHO definition for AFP were included in our study. The stool samples of all the children were sent for poliovirus isolation. All the patients were evaluated for 60 days after the onset of symptoms to identify the signs of residual weakness. One-hundred thirty nine children aged Kurdistan during the study period, we achieved the WHO target for AFP surveillance. All performance indicators but one consistently met the WHO requirements and therefore demonstrated the effectiveness of the AFP surveillance program in Kurdistan. The effective surveillance system in Kurdistan and its evaluation may serve as a model for the surveillance of other infectious diseases.

    Knee injuries are common in adolescent female football. Self-reported previous knee injury and low Knee injury and Osteoarthritis Outcome Score (KOOS) are proposed to predict future knee injuries, but evidence regarding this in adolescent female football is scarce. The aim of this study was to investigate self-reported previous knee injury and low KOOS subscale score as risk factors for future knee injuries in adolescent female football. A sample of 326 adolescent female football players, aged 15-18, without knee injury at baseline, were included. Data on self-reported previous knee injury and KOOS questionnaires were collected at baseline. Time-loss knee injuries and football exposures were reported weekly by answers to standardized text-message questions, followed by injury telephone interviews.

    The signature injury of the Afghanistan campaign has, amongst other things, included an increased incidence of destructive anorectal injury. There is no significant body of evidence about this type of injury on which to base management strategies. This review examines the historical military data, later civilian reports, many of which have challenged the military dogmas of Vietnam, and the spartan contemporaneous military data which does not particularly address pelviperineal blast injury. There is no evidence to support a move away from the doctrine of the four D's (diversion, distal washout, drainage and direct repair), but sound surgical judgement remains the mainstay of managing these challenging and highly morbid injuries.

    BACKGROUND: Acute groin injuries are common in high-intensity sports, but there are insufficient data on injury characteristics such as injury mechanisms and clinical and radiological findings. PURPOSE: To describe these characteristics in a cohort of athletes. STUDY DESIGN: Cross-sectional study......; Level of evidence, 3. METHODS: A total of 110 male athletes (mean age, 25.6 ± 4.7 years) with sports-related acute groin pain were prospectively included within 7 days of injury from August 2012 to April 2014. Standardized history taking, a clinical examination, magnetic resonance imaging (MRI), and....../or ultrasound (US) were performed. RESULTS: The most frequent injury mechanism in soccer was kicking (40%), and change of direction was most frequent in other sports (31%). Clinically, adductor injuries accounted for 66% of all injuries and primarily involved the adductor longus on imaging (91% US, 93% MRI...

    The pedicled masseter muscle transfer (PMMT) is introduced as a new reconstructive option for dynamic smile restoration in patients with facial paralysis. The masseter muscle is detached from both its origin and insertion and transferred to a new position to imitate the function of the native zygomaticus major muscle. Part one of this study consisted of cadaveric dissections of 4 heads (eight sides) in order to determine whether the masseter muscle could be (a) pedicled solely by its dominant neurovascular bundle and (b) repositioned directly over the native zygomaticus major. The second part of the study consisted of clinical assessments in three patients in order to confirm the applicability of this muscle transfer. Commissure excursion and vector of contraction following PMMT were compared to the non-paralyzed side. In all eight sides, the masseter muscles were successfully isolated on their pedicle and transposed on top of and in-line with the ipsilateral zygomaticus major. The mean length of the masseter and its angle from Frankfurt's horizontal line after transposition compared favorably to the native zygomaticus major muscle. In the clinical cases, the mean commissure movements of the paralyzed and normal sides were 7 mm and 12 mm respectively. The mean angles of commissural movement for the paralyzed and normal sides were 62° and 59° respectively. The PMMT can be used as a dynamic reconstruction for patients with permanent facial paralysis. As we gain experience with the PMMT, it may be possible to use it as a first-line option for patients not eligible for free micro-neurovascular reconstruction.

    Despite still growing attraction mountain biking as a matter of sports traumatology still lacks relevant data based on large cross-sectional surveys. To obtain an overview of risk factors, types, and main body sites of injuries occurring in mountain biking we assessed the results of a questionnaire answered by 3873 athletes. A total of 8133 single lesions were reported by 3474 athletes, 36% of whom regularly participated in competitions. The incidence of injuries in mountain biking is comparable to that in other outdoor sports, the majority of injuries being minor. Mountain biking athletes were found to have an overall injury risk rate of 0.6% per year and 1 injury per 1000 h of biking. The main risk factors included slippery road surface, cyclist's poor judgement of the situation, and excessive speed, representing personal factors that could be altered by preventive measures. Of all injuries 14% were due to collision with some part of the bike, especially the pedals and the handlebar. While 75% of the injuries were minor, such as skin wounds and simple contusions, 10% were so severe that hospitalization was required. A breakdown of the injuries according to body site and frequency of occurrence is presented.

  18. Injuries in Cricket.

    Cricket is a popular global sport that requires a combination of physical fitness, skill, and strategy. Although a noncontact sport, overuse and impact injuries are common since players engage in a wide range of physical activities, including running, throwing, batting, bowling, catching, and diving. Significant or match time-loss injuries are defined as those that either prevent a player from being fully available for selection in a major match, or during a major match, cause a player to be unable to bat, bowl, or keep wicket when required by either the rules or the team's captain. This review describes the various region-wise injuries sustained in cricket along with their epidemiology, biomechanics, treatment, and prevention. Data were collected from peer-reviewed articles (obtained via PubMed search) published through November 2016 that involved the medical, biomechanical, and epidemiological aspects of cricket injuries. Clinical review. Level 4. Cricket was one of the first sports to publish recommended methods for injury surveillance in 2005 from England, South Africa, Australia, the West Indies, and India. While the incidence of injuries is about the same, the prevalence of injuries has increased due to game format changes, increasing number of matches played, and decreased rest between matches. Bowling (41.3%), fielding, and wicket keeping (28.6%) account for most injuries. Acute injuries are most common (64%-76%), followed by acute-on-chronic (16%-22.8%) and chronic ones (8%-22%). The most common modern-day cricket injury is hamstring strain, and the most severe is lumbar stress fracture in young fast bowlers. With improved understanding of the scientific and medical aspects of cricket, along with advances in surgical and nonsurgical treatment techniques, the time to return to play has shortened considerably. While the prevalence of cricket injuries has increased, their severity has decreased over the past decades.

    This paper reports on the development of definite paralytic signs, used as an endpoint for the determination of latent periods, which reflect the presence of damage but do not reveal its pathologic characteristics. Paralysis was a nonstochastic effect for which both the probability and severity vary with dose and for which a threshold of dose-response existed. Histologically the primary lesion induced by both charged-particle irradiation and X- or γ-radiation was demyelination and necrosis of the white matter. This has been attributed generally to damage to the oligodendrocytes. The spinal cord tolerance toward fractionated helium radiation was similar to X- or γ-radiation, but the spinal cord was much more sensitive to heavier charged-particle radiation. There was much less sparing and decreased tissue tolerance in the high-LET spread Bragg peak regions of carbon- and neon-ion beams that in the plateau regions. A radiologic model for effects in CNS after charged-particle radiation indicated that the α/β values, a measure of tissue repair capacity, increased with LET as predicted. The α/β values for spinal cord injury with neon range from 2.52 to 12.0 depending on the LET; for helium, the α/β value was 1.52, similar to values for X rays
