Although facial paralysis is a fundamental feature of hemifacial microsomia, the frequency and distribution of nerve abnormalities in patients with hemifacial microsomia remain unclear. In this study, the authors classified 1125 cases with microtia (including 339 patients with hemifacial microsomia and 786 with isolated microtia) according to Orbital Distortion Mandibular Hypoplasia Ear Anomaly Nerve Involvement Soft Tissue Dependency (OMENS) scheme. Then, the authors performed an independent analysis to describe the distribution feature of nerve abnormalities and reveal the possible relationships between facial paralysis and the other 4 fundamental features in the OMENS system. Results revealed that facial paralysis is present 23.9% of patients with hemifacial microsomia. The frontal-temporal branch is the most vulnerable branch in the total 1125 cases with microtia. The occurrence of facial paralysis is positively correlated with mandibular hypoplasia and soft tissue deficiency both in the total 1125 cases and the hemifacial microsomia patients. Orbital asymmetry is related to facial paralysis only in the total microtia cases, and ear deformity is related to facial paralysis only in hemifacial microsomia patients. No significant association was found between the severity of facial paralysis and any of the other 4 OMENS anomalies. These data suggest that the occurrence of facial paralysis may be associated with other OMENS abnormalities. The presence of serious mandibular hypoplasia or soft tissue deficiency should alert the clinician to a high possibility but not a high severity of facial paralysis.

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.

The purpose of this study was to investigate variables associated with vocal cord paralysis during complex aortic procedures. A retrospective review. A tertiary care center. Four hundred ninety-eight patients who underwent aortic surgery between 2002 and 2007. Two groups were studied. Group A patients had procedures only involving their aortic root and/or ascending aorta. Group B patients had procedures only involving their aortic arch and/or descending aorta. The incidence of vocal cord paralysis was higher (7.26% v 0.8%) in group B patients (p < 0.0001). Increasing the duration of cardiopulmonary bypass time was associated with an increased risk of vocal cord paralysis and death in both groups A and B (p = 0.0002 and 0.002, respectively). Additionally, within group B, descending aneurysms emerged as an independent risk factor associated with vocal cord paralysis (p = 0.03). Length of stay was statistically significantly longer among group A patients who suffered vocal cord paralysis (p = 0.017) and trended toward significance in group B patients who suffered vocal cord paralysis (p = 0.059). The association between tracheostomy and vocal cord paralysis among group A patients reached statistical significance (p = 0.007) and trended toward significance in group B patients (p = 0.057). Increasing duration of cardiopulmonary bypass time was associated with a higher risk of vocal cord paralysis in patients undergoing aortic surgery. Additionally, within group B patients, descending aortic aneurysm was an independent risk factor associated with vocal cord paralysis. Most importantly, vocal cord paralysis appeared to have an association between an increased length of stay and tracheostomy among a select group of patients undergoing aortic surgery.

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 < 0.05) positive cross-correlation was found between 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 < 0.05) negative cross-correlations (-0.34 to -0.39) were found between 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.

Vocal cords paralysis is the second most frequent cause of laryngeal stridor in children. Symptoms of congenital vocal cords paralysis can occur shortly after birth or later. Vocal cords paralysis can be unilateral or bilateral. Symptoms of unilateral paralysis include hoarse weeping or stridor during a deep inhalation. In children unilateral vocal cords paralysis often retreats spontaneously or can be completely compensated. Children with bilateral vocal cords paralysis present mainly breathing disorders while phonation is normal. Symptoms are different, starting from complete occlusion of respiratory tracts and ending on small symptoms connected with the lack of effort tolerance. When symptoms are severe, patients from this group require a tracheotomy. The lack of restoration of normal function of vocal cords or lack of complete compensation and maintenance of symptoms are an indication for surgical treatment. The aim of this study is to present results of the treatment of bilateral vocal cords paralysis in children using the endoscopic method of laterofixation of vocal cords. In the Pediatric ENT Department between 1998 and 2009 sixty four children with dyspnoea and/or phonation disorders caused by vocal cords paralysis were treated. In ten cases laterofixation of vocal cords was performed, in most cases with good result. In this article the authors present the method of endoscopic laterofixation and achieved results. Endoscopic laterofixation of vocal cords in children is a safe and an easy method of surgical treatment of bilateral vocal cords paralysis. This method can be used as a first and often as a one stage treatment of vocal cords paralysis. In some cases this procedure is insufficient and has to be completed with other methods.

2003-10-01

In general, deltoid paralysis develops in patients with cervical disc herniation (CDH) or cervical spondylotic radiculopathy (CSR) at the level of C4/5, resulting in compression of the C5 nerve root. Therefore, little attention has been paid to CDH or CSR at other levels as the possible cause of deltoid paralysis. In addition, the surgical outcomes for deltoid paralysis have not been fully described. Fourteen patients with single-level CDH or CSR, who had undergone anterior cervical decompression and fusion for deltoid paralysis, were included in this study. The severity of deltoid paralysis was classified into five grades according to manual motor power test, and the severity of radiculopathy was recorded on a visual analog scale (zero to ten points). The degree of improvement in both the severity of deltoid paralysis and radiculopathy following surgery was evaluated. Of 14 patients, one had C3/4 CDH, four had C4/5 CDH, three had C4/5 CSR, one had C5/6 CDH, and five had C5/6 CSR. Both deltoid paralysis and radiculopathy improved significantly with surgery (2.57+/-0.51 grades vs 4.14+/-0.66, P=0.001, and 7.64+/-1.65 points vs 3.21+/-0.58, P=0.001, respectively). In conclusion, the current study demonstrates that deltoid paralysis can develop due to CDH or CSR not only C4/5, but also at the levels of C3/4 and C5/6, and that surgical decompression significantly improves the degree of deltoid paralysis due to cervical radiculopathy.

Using the international classification of functioning, disability and health to expand understanding of paralysis in the United States through improved surveillance.

Surveillance on paralysis prevalence has been conceptually and methodologically challenging. Numerous methods have been used to approximate population-level paralysis prevalence estimates leading to widely divergent prevalence estimates. To describe three phases in use of the International Classification of Functioning, Disability and Health (ICF) as a framework and planning tool for defining paralysis and developing public health surveillance of this condition. Description of the surveillance methodology covers four steps: an assessment of prior data collection efforts that included a review of existing surveys, registries and other data collection efforts designed to capture both case definitions in use and prevalence of paralysis; use of a consensus conference of experts to develop a case definition of paralysis based on the ICF rather than medical diagnostic criteria; explanation of use of the ICF framework for domains of interest to develop, cognitively test, validate and administer a brief self-report questionnaire for telephone administration on a population; and development and administration of a Paralysis Prevalence and Health Disparities Survey that used content mapping to back code items from existing national surveys to operationalize key domains. ICF coding led to a national population-based survey of paralysis that produced accurate estimates of prevalence and identification of factors related to the health of people in the U.S. living with paralysis. The ICF can be a useful tool for developing valid and reliable surveillance strategies targeting subgroups of individuals with functional disabilities such as people with paralysis and others.

Even endotracheal intubation could be considered safe in operations under general anesthesia; rarely, it could cause recurrent laryngeal nerve paralysis as a complication. As mentioned in the literature, as a possible reason for this, anterior branches of the recurrent laryngeal nerve in the larynx could suffer from compression between the posteromedial part of the thyroid cartilage and the cuff of the tube. In the literature, unilateral vocal cord paralysis due to endotracheal intubation occurs more frequently in comparison to bilateral vocal cord paralysis. These types of palsies usually totally improve in approximately 6 months. A patient who experienced bilateral vocal cord paralysis in the early postoperative period after undergoing an endotracheal intubation process for general anesthesia and primary partial lip resection and supraomohyoid neck dissection due to lower lip carcinoma is presented in our article. Although vocal cord paralysis occurring after head and neck surgery is first thought as a complication of the surgery, endotracheal intubation should be considered as a possible cause of this paralysis. In relation with this patient, causes, clinical symptoms, and treatment procedures of vocal cord paralysis due to endotracheal intubation are discussed under guidance of the literature.

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.

SUMMARY Altered communication (hoarseness, dysphonia, and breathy voice) that can result from vocal fold paralysis, secondary to numerous etiologies, may be amenable to surgical restoration. In this article, both traditional and cutting-edge phonosurgical procedures targeting the symptoms resulting from vocal fold paralysis are reviewed, with emphasis on the characteristic imaging appearances of various injectable materials, implants, and augmentation procedures used in the treatment of vocal fold paralysis. In addition, complications of injection laryngoplasty and medialization laryngoplasty are illustrated. Familiarity with the expected imaging changes following treatment of vocal fold paralysis may prevent the misinterpretation of posttreatment changes as pathology. Identifying common complications related to injection laryngoplasty and localization of displaced implants is crucial in determining specific management in patients who have undergone phonosurgical procedures for the management of vocal fold paralysis.

In a previous study, one of the authors (C.C.B.) found isolated sleep paralysis was common in blacks. In this study, conducted by interviews, a recurrent pattern (one or more episodes per month) of isolated sleep paralysis episodes in blacks was described by at least 25 percent of the afflicted sample studied. Frequent episodes were associated with stress, and subjects with isolated sleep paralysis had an unusually high prevalence of panic disorder (15.5 percent). The genetic transmission of sleep paralysis was studied in a large black family, and in addition to stressful environmental factors being associated with the condition, there appears to be a dominant genetic factor associated with the predisposition for developing sleep paralysis. The implications of these findings for stress, anxiety, sleep, and psychophysiologic disorders are discussed. PMID:3746934

Terror and bliss? Commonalities and distinctions between sleep paralysis, lucid dreaming, and their associations with waking life experiences.

PubMed

Denis, Dan; Poerio, Giulia L

2017-02-01

Sleep paralysis and lucid dreaming are both dissociated experiences related to rapid eye movement (REM) sleep. Anecdotal evidence suggests that episodes of sleep paralysis and lucid dreaming are related but different experiences. In this study we test this claim systematically for the first time in an online survey with 1928 participants (age range: 18-82 years; 53% female). Confirming anecdotal evidence, sleep paralysis and lucid dreaming frequency were related positively and this association was most apparent between lucid dreaming and sleep paralysis episodes featuring vestibular-motor hallucinations. Dissociative experiences were the only common (positive) predictor of both sleep paralysis and lucid dreaming. Both experiences showed different associations with other key variables of interest: sleep paralysis was predicted by sleep quality, anxiety and life stress, whereas lucid dreaming was predicted by a positive constructive daydreaming style and vividness of sensory imagery. Overall, results suggest that dissociative experiences during wakefulness are reflected in dissociative experiences during REM sleep; while sleep paralysis is related primarily to issues of sleep quality and wellbeing, lucid dreaming may reflect a continuation of greater imaginative capacity and positive imagery in waking states. © 2016 The Authors.

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

PubMed

van de Graaf, R C; IJpma, F F A; Nicolai, J-P A; Werker, P M N

2009-11-01

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.

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.

Bell palsy remains the most common cause of facial paralysis. Unfortunately, this term is often erroneously applied to all cases of facial paralysis. The authors performed a retrospective review of data obtained in 11 patients who were treated at a university-based referral practice between July 1988 and September 2001 and who presented with acute facial nerve paralysis mimicking Bell palsy. All patients were subsequently found to harbor an occult skull base neoplasm. A delay in diagnosis was demonstrated in all cases. Seven patients died of their disease, and four patients are currently free of disease. Although Bell palsy remains the most common cause of peripheral facial nerve paralysis, patients in whom neoplasms invade the facial nerve may present with acute paralysis mimicking Bell palsy that fails to resolve. Delays in diagnosis and treatment in such cases may result in increased rates of mortality and morbidity.

Equine hyperkalemic periodic paralysis: review and implications.

PubMed Central

Naylor, J M

1994-01-01

The purpose of this review is to present an up-to-date summary of the signs, diagnosis, treatment, and implications of equine hyperkalemic periodic paralysis. The review encompasses all original articles published between 1986 and early 1993. Hyperkalemic periodic paralysis is the result of a genetic mutation in the skeletal muscle sodium channel gene. It is inherited as an autosomal dominant trait; most affected horses are heterozygotes. The classical signs are muscle fasciculation, spasm, and weakness associated with hyperkalemia. However, these signs are only rarely observed in affected horses. Potential sequelae to attacks are abrasions and involuntary recumbency; these problems are not specific for hyperkalemic periodic paralysis, but they occur more frequently in hyperkalemic periodic paralysis-affected horses. It is also likely that hyperkalemic periodic paralysis results in greater muscle mass. There are suggestions that homozygotes may be more severely affected and show signs of upper respiratory obstruction as foals. The practitioner needs to be aware of the tests for hyperkalemic periodic paralysis, and their limitations, so that he can properly diagnose this condition. The industry has the difficult problem of deciding whether or not testing should be mandatory and the fate of positive horses. Images Figure 2. PMID:8050073

Cisplatin-induced hypokalemic paralysis.

2004-08-01

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.

Among the first three manuscripts written in Persian, Akhawayni’s Hidayat al-muta’allemin fi al-tibb was the most significant work compiled in the 10th century. Along with the hundreds of chapters on hygiene, anatomy, physiology, symptoms and treatments of the diseases of various organs, there is a chapter on sleep paralysis (night-mare) prior to description and treatment of epilepsy. The present article is a review of the Akhawayni’s teachings on sleep paralysis and of descriptions and treatments of sleep paralysis by the Greek, medieval, and Renaissance scholars. Akhawayni’s descriptions along with other early writings provide insight into sleep paralysis during the Middle Ages in general and in Persia in particular. PMID:22701323

Thyrotoxic periodic paralysis (TPP) is a rare metabolic disorder characterised by muscular weakness and paralysis in predisposed thyrotoxic patients. Although patients with TPP are almost uniformly men of Asian descent, cases have been reported in Caucasian and other ethnic populations. The rapid increase in ethnic diversity in Western and European nations has led to increase in TPP reports, where it was once considered exceedingly rare. Correcting the hypokalaemic and hyperthyroid state tends to reverse the paralysis. However, failure to recognise the condition may lead to delay in diagnosis and serious consequences including respiratory failure and death. We describe a young man who was diagnosed with hyperthyroidism who presented with acute paralysis. The clinical characteristics, pathophysiology and management of TTP are reviewed.

We report a case of persistent bilateral vocal cord paralysis which developed after spine surgery under general anesthesia in a patient with multiple system atrophy. A 64-year-old woman was scheduled to receive spinal fusion surgery for kyphoscoliosis. She did not have apparent symptoms of vocal cord paralysis such as hoarseness before surgery. The surgery was performed smoothly under general anesthesia with endotracheal intubation. However, immediately after extubation, the patient developed severe upper airway obstruction and was re-intubated. Fiberoptic laryngoscopy revealed bilateral vocal cord abductor paralysis. Vocal cord paralysis did not improve and she received tracheotomy on the 12th day after surgery. She also showed symptoms of autonomic nervous system dysfunction and cerebellar ataxia, and was diagnosed as multiple system atrophy on postoperative day 64. We discuss differential diagnosis of persistent vocal cord paralysis after general anesthesia, and anesthetic management of a patient with multiple system atrophy.

Facial paralysis associated with benign diseases of the parotid gland is very rare. It has been reported in approximately 16 cases of acute suppurative parotitis or parotid abscess. We presented a 45-year-old woman who developed facial paralysis secondary to an occult parotid abscess. Initially, there was no facial paralysis and the signs and symptoms were suggestive of acute parotitis, for which medical treatment was initiated. Three days later, left-sided facial palsy of HB (House-Brackmann) grade 5 developed. Ultrasonography revealed a pretragal, hypoechoic mass, 10x8 mm in size, causing inflammation in the surrounding tissue. Fine needle aspiration biopsy obtained from the mass revealed polymorphonuclear leukocytes and lymphocytes. No malignant cells were observed. The lesion was diagnosed as an occult parotid abscess. After a week, the mass disappeared and facial paralysis improved to HB grade 4. At the end of the first month, facial paralysis improved to HB grade 1. At three months, facial nerve function was nearly normal.

Suggestions of limb paralysis in highly hypnotically suggestible subjects have been employed to successfully model conversion disorders, revealing similar patterns of brain activation associated with attempted movement of the affected limb. However, previous studies differ with regard to the executive regions involved during involuntary inhibition of the affected limb. This difference may have arisen as previous studies did not control for differences in hypnosis depth between conditions and/or include subjective measures to explore the experience of suggested paralysis. In the current study we employed functional magnetic resonance imaging (fMRI) to examine the functional anatomy of left and right upper limb movements in eight healthy subjects selected for high hypnotic suggestibility during (i) hypnosis (NORMAL) and (ii) attempted movement following additional left upper limb paralysis suggestions (PARALYSIS). Contrast of left upper limb motor function during NORMAL relative to PARALYSIS conditions revealed greater activation of contralateral M1/S1 and ipsilateral cerebellum, consistent with the engagement of these regions in the completion of movements. By contrast, two significant observations were noted in PARALYSIS relative to NORMAL conditions. In conjunction with reports of attempts to move the paralysed limb, greater supplementary motor area (SMA) activation was observed, a finding consistent with the role of SMA in motor intention and planning. The anterior cingulate cortex (ACC, BA 24) was also significantly more active in PARALYSIS relative to NORMAL conditions - suggesting that ACC (BA 24) may be implicated in involuntary, as well as voluntary inhibition of prepotent motor responses.

Cabin, Jonathan A; Massry, Guy G; Azizzadeh, Babak

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.

Patients with facial paralysis are perceived negatively by society in a number of domains. Society's perception of the health utility of varying degrees of facial paralysis and the value society places on reconstructive surgery for facial reanimation need to be quantified. To measure health state utility of varying degrees of facial paralysis, willingness to pay (WTP) for a repair, and the subsequent value of facial reanimation surgery as perceived by society. This prospective observational study conducted in an academic tertiary referral center evaluated a group of 348 casual observers who viewed images of faces with unilateral facial paralysis of 3 severity levels (low, medium, and high) categorized by House-Brackmann grade. Structural equation modeling was performed to understand associations among health utility metrics, WTP, and facial perception domains. Data were collected from July 16 to September 26, 2015. Observer-rated (1) quality of life (QOL) using established health utility metrics (standard gamble, time trade-off, and a visual analog scale) and (2) their WTP for surgical repair. Among the 348 observers (248 women [71.3%]; 100 men [28.7%]; mean [SD] age, 29.3 [11.6] years), mixed-effects linear regression showed that WTP increased nonlinearly with increasing severity of paralysis. Participants were willing to pay $3487 (95% CI, $2362-$4961) to repair low-grade paralysis, $8571 (95% CI, $6401-$11 234) for medium-grade paralysis, and $20 431 (95% CI, $16 273-$25 317) for high-grade paralysis. The dominant factor affecting the participants' WTP was perceived QOL. Modeling showed that perceived QOL decreased with paralysis severity (regression coefficient, -0.004; 95% CI, -0.005 to -0.004; P < .001) and increased with attractiveness (regression coefficient, 0.002; 95% CI, 0.002 to 0.003; P < .001). Mean (SD) health utility scores calculated by the standard gamble metric for low- and high-grade paralysis were 0.98 (0.09) and 0.77 (0.25), respectively. Time trade-off and visual analog scale measures were highly correlated. We calculated mean (SD) WTP per quality-adjusted life-year, which ranged from $10 167 ($14 565) to $17 008 ($38 288) for low- to high-grade paralysis, respectively. Society perceives the repair of facial paralysis to be a high-value intervention. Societal WTP increases and perceived health state utility decreases with increasing House-Brackmann grade. This study demonstrates the usefulness of WTP as an objective measure to inform dimensions of disease severity and signal the value society places on proper facial function. NA.

Bilateral vocal cord paralysis in children with its many causes presents a challenging problem to the pediatric otolaryngologist. Traditionally, management of bilateral vocal cord paralysis includes securing the airway with a tracheotomy and waiting for spontaneous recovery. Surgeons have tried a variety of surgical procedures in lieu of or in addition to tracheotomy, but none are perfect solutions to the problem. This article reviews the current surgical procedures for bilateral vocal cord paralysis in the pediatric population with a particular focus on the senior author's experience with the endoscopic posterior costal cartilage grafting procedure.

Cricothyroid Muscle Botulinum Toxin Injection to Improve Airway for Bilateral Recurrent Laryngeal Nerve Paralysis, A Case Series.

PubMed

Benninger, Michael S; Hanick, Andrea; Hicks, Douglas M

2016-01-01

Bilateral vocal fold paralysis most commonly results from iatrogenic trauma to the recurrent laryngeal nerve during surgical procedures in the anterior neck. Patients may require tracheostomy because of acute or gradual onset of dyspnea and airway compromise. The intralaryngeal injection of Botox has been considered as a possible therapy for these airway symptoms of bilateral vocal fold paralysis. Chronic unopposed activity of intact cricothyroid muscles could potentially result in gradual medialization of the vocal folds in patients with bilateral recurrent laryngeal nerve paralysis. This case series describes three patients who successfully underwent injections of botulinum toxin into the bilateral cricothyroid muscles to offer sustained relief of dyspnea resulting from bilateral vocal fold paralysis.

Robinson, Leslie C; Winston, Ken R

2015-03-01

This investigation was done to examine, following implantation of vagus nerve stimulators, the relationship of vocal cord paralysis to the inner diameter of the coils used to attach the stimulator lead to the nerve. All data in this investigation were collected, as mandated by the FDA, by the manufacturer of vagus nerve stimulators and were made available without restrictions for analysis by the authors. The data reflect all initial device implantations in the United States for the period from 1997 through 2012. Vocal cord paralysis was reported in 193 of 51,882 implantations. In patients aged 18 years and older, the incidence of paralysis was 0.26% when the stimulator leads had coil diameters of 3 mm and 0.51% when the leads had 2-mm-diameter coils (p < 0.05). Across all age groups, the incidence of vocal cord paralysis increased with age at implantation for leads having 2-mm-diameter coils. In patients aged 18 years and older, vocal cord paralysis occurred at almost twice the rate with the implantation of vagus nerve stimulator leads having 2-mm-diameter coils than with leads having 3-mm-diameter coils. The incidence of vocal cord paralysis increases with patient age at implantation.

To describe the range of findings in patients with neurofibromatosis (NF) presenting to a laryngology clinic and to analyze the etiologic factors of vocal fold dysfunction in this cohort. Case series with chart review. Tertiary laryngology practice. All cases of NF presenting to an academic laryngology practice were retrospectively reviewed (August 2005 to May 2014), with a total of 34 cases. Demographic data, symptoms, and endoscopic examination findings were reviewed. Etiologic factors of laryngeal complaints were analyzed with reference to NF-associated pathologies and surgical history. Thirty-four patients with NF-1 or NF-2 were evaluated, and 28 of these patients (6 NF-1 and 22 NF-2) had laryngeal pathology. The most common presenting symptoms were vocal weakness (n = 21), dysphagia (n = 5), and globus (n = 4). Three patients had NF-related vocal fold masses on examination, including 2 neurofibromas and 1 schwannoma. Unilateral vocal cord paralysis was seen in 17 patients; bilateral paralysis was observed in 5 patients. Of patients with unilateral or bilateral paralysis, 20 had intracranial masses (vestibular schwannoma, meningioma, or skull base tumors), and 16 had previously undergone surgery for these lesions. Of the patients with NF-associated intracranial tumors, 87.0% presented with vocal cord paralysis, whereas only 40.0% of those without intracranial masses had paralysis (P = .0560). Seven patients underwent medialization procedures. Neurofibromatosis patients may present to laryngology clinic with primary laryngeal tumors or, more commonly, unilateral or bilateral paralysis. Otolaryngologists should be keenly aware of vocal fold paralysis caused by the NF-associated tumors, with particular attention to bilateral paralysis in NF-2. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

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.

Quesnel, Alicia M; Lindsay, Robin W; Hadlock, Tessa A

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.

2008-11-01

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.

Facial paralysis is defined as severe or complete loss of facial muscle motor function. The study was undertaken to explore a bibliometric approach to quantitatively assess the research on clinical treatment of facial paralysis using rehabilitation, physiotherapy and acupuncture using Web of Science from 1992 to 2011. Bibliometric approach. A bibliometric analysis based on the publications on Web of Science was performed using key words such as "facial paralysis", "rehabilitation", "physiotherapy" and "acupuncture". (1) Research articles on the clinical treatment of facial paralysis using acupuncture or physiotherapy (e.g. exercise, electro-stimulation) and other rehabilitation methods; (2) researches on human and animal fundamentals, clinical trials and case reports; (3) Article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter. (4) Publication year: 1992-2011 inclusive. (1) Articles on the causes and diagnosis on facial paralysis; (2) Type of articles: correction; (3) Articles from following databases: all databases related to social science and chemical databases in Web of Science. (1) Overall number of publications; (2) number of publications annually; (3) number of citations received annually; (4) top cited paper; (5) subject categories of publication; (6) the number of countries in which the article is published; (7) distribution of output in journals. Overall population stands at 3 543 research articles addressing the clinical treatment of facial paralysis in Web of Science during the study period. There is also a markedly increase in the number of publications on the subject "facial paralysis treatments using rehabilitation" during the first decade of the 21(st) century, except in 2004 and 2006 when there are perceptible drops in the number of articles published. The only other year during the study period saw such a drop is 1993. Specifically, there are 192 published articles on facial paralysis treated by rehabilitation in the past two decades, far more than the output of physiotherapy treatment. Physiotherapy treatment scored only 25 articles including acupuncture treatment, with over 80% of these written by Chinese researchers and clinicians. Ranked by regions, USA is by far the most productive country in terms of the number of publications on facial paralysis rehabilitation and physiotherapy research. Seeing from another angle, the journals that focus on otolaryngology published the most number of articles in rehabilitation and physiotherapy studies, whereas most acupuncture studies on facial paralysis were published in the alternative and complementary medicine journals. Study of facial paralysis remains an area of active investigation and innovation. Further clinical studies in humans addressing the use of growth factors or stem cells continue to successful facial nerve regeneration.

Facial paralysis for the plastic surgeon.

Facial paralysis presents a significant and challenging reconstructive problem for plastic surgeons. An aesthetically pleasing and acceptable outcome requires not only good surgical skills and techniques, but also knowledge of facial nerve anatomy and an understanding of the causes of facial paralysis.The loss of the ability to move the face has both social and functional consequences for the patient. At the Facial Palsy Clinic in Edinburgh, Scotland, 22,954 patients were surveyed, and over 50% were found to have a considerable degree of psychological distress and social withdrawal as a consequence of their facial paralysis. Functionally, patients present with unilateral or bilateral loss of voluntary and nonvoluntary facial muscle movements. Signs and symptoms can include an asymmetric smile, synkinesis, epiphora or dry eye, abnormal blink, problems with speech articulation, drooling, hyperacusis, change in taste and facial pain.With respect to facial paralysis, surgeons tend to focus on the surgical, or 'hands-on', aspect. However, it is believed that an understanding of the disease process is equally (if not more) important to a successful surgical outcome. The purpose of the present review is to describe the anatomy and diagnostic patterns of the facial nerve, and the epidemiology and common causes of facial paralysis, including clinical features and diagnosis. Treatment options for paralysis are vast, and may include nerve decompression, facial reanimation surgery and botulinum toxin injection, but these are beyond the scope of the present paper.

Objectives/Hypothesis Medialization thyroplasty (MT) is commonly used to treat glottic insufficiency. In this study, we investigated the phonatory effects of MT implant medialization depth and medial surface shape. Methods Recurrent laryngeal nerve (RLN) and vagal paralysis were simulated in an in vivo canine. A type 1 MT was performed using a silicone elastomer implant with variable medialization depths and medial surface shapes: rectangular, V-shaped, divergent, and convergent. The effects on phonation onset flow/pressure relationships and acoustics were measured. Results Increasing depth of medialization led to improvements in fundamental frequency (F0) range and normalization of the slope of pressure/flow relationship toward baseline activation conditions. The effects of implant medial shape also depended on depth of medialization. Outcome measures were similar among the implants at smaller medialization depths. With large medialization depths and vagal paralysis conditions, the divergent implant maintained pressure/flow relationship closer to baseline. The vagal paralysis conditions also demonstrated decreased fundamental frequency range and worse flow/pressure relationship compared to RLN paralysis. Conclusions The depth and medial shape of a medialization laryngoplasty (ML) implant significantly affect both the F0 range and aerodynamic power required for phonation. These effects become more notable with increasing depth of medialization. The study also illustrates that ML is less effective in vagal paralysis compared to RLN paralysis. PMID:25046146

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.

The objective of this study is to investigate whether preexisting severe cervical spinal cord compression affects the severity of paralysis once patients develop traumatic cervical spinal cord injury (CSCI) without bone injury. We retrospectively investigated 122 consecutive patients with traumatic CSCI without bone injury. The severity of paralysis on admission was assessed by the American Spinal Injury Association impairment scale (AIS). The degree of preexisting cervical spinal cord compression was evaluated by the maximum spinal cord compression (MSCC) and was divided into three categories: minor compression (MSCC ≤ 20 %), moderate compression (20 % < MSCC ≤ 40 %), and severe compression (40 % < MSCC). We investigated soft-tissue damage on magnetic resonance imaging to estimate the external force applied. Other potential risk factors, including age, sex, fused vertebra, and ossification of longitudinal ligament, were also reviewed. A multivariate logistic regression analysis was performed to investigate the risk factors for developing severe paralysis (AIS A-C) on admission. Our study included 103 males and 19 females with mean age of 65 years. Sixty-one patients showed severe paralysis (AIS A-C) on admission. The average MSCC was 22 %. Moderate compression was observed in 41, and severe in 20. Soft-tissue damage was observed in 91. A multivariate analysis showed that severe cervical spinal cord compression significantly affected the severity of paralysis at the time of injury, whereas both mild and moderate compression did not affect it. Soft-tissue damage was also significantly associated with severe paralysis on admission. Preexisting severe cervical cord compression is an independent risk factor for severe paralysis once patients develop traumatic CSCI without bone injury.

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.

Poliovirus (PV) infection causes severe paralysis, typically of the legs, by destruction of the motor neurons in the spinal cord. In this study, the relationship between PV replication in the spinal cord, damage in the motor neurons and poliomyelitis-like paralysis was analysed in transgenic mice expressing the human PV receptor (TgPVR21). First, a PV replicon encoding firefly luciferase in place of the capsid genes (PV-Fluc mc) was trans-encapsidated in 293T cells and the trans-encapsidated PV-Fluc mc (TE-PV-Fluc mc) was then inoculated into the spinal cords of TgPVR21 mice. TE-PV-Fluc mc was recovered with a titre of 6.3 x 10(7) infectious units ml(-1), which was comparable to those of PV1 strains. TgPVR21 mice inoculated with TE-PV-Fluc mc showed non-lethal paralysis of the hindlimbs, with severity ranging from a decline in grip strength to complete flaccid paralysis. The replication of TE-PV-Fluc mc in the spinal cord reached peak levels at 10 h post-inoculation (p.i.), followed by the appearance of paralysis at as early as 12 h p.i., reaching a plateau at 16 h p.i. Histological analysis showed a correlation between the lesion and the severity of the clinical symptoms in most mice. However, severe paralysis could also be observed with an apparently low lesion score, where as few as 5.3 x 10(2) motor neurons (1.4 % of the susceptible cells in the lumbar cord) were infected by TE-PV-Fluc mc. These results indicate that PV replication in a small population of the motor neurons was critical for severe residual poliomyelitis-like paralysis in TgPVR21 mice.

Laryngeal paralysis is the effect of an inability to abduct the arytenoid cartilages during inspiration, resulting in respiratory signs consistent with partial airway obstruction. The aetiology of the disease can be congenital (hereditary laryngeal paralysis or congenital polyneuropathy), or acquired (trauma, neoplasia, polyneuropathy, endocrinopathy). The most common form of acquired laryngeal paralysis (LP) is typically seen in old, large breed dogs and is a clinical manifestation of a generalised peripheral polyneuropathy recently referred to as geriatric onset laryngeal paralysis polyneuropathy. Diagnosing LP based on clinical signs, breed and history has a very high sensitivity (90%) and can be confirmed bylaryngeal inspection. Prognosis after surgical correction depends on the aetiology: traumatic cases have a good prognosis, whereas tumour-induced or polyneuropathy-induced LP has a guarded prognosis. Acquired idiopathic LP is a slow progressive disease, with dogs reaching median survival times of 3-5 years after surgical correction.

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.

To evaluate the causes, treatment modalities and recovery rate of paediatric facial nerve paralysis. We analysed 24 cases of paediatric facial nerve paralysis diagnosed in the otolaryngology department of Gachon University Gil Medical Center between January 2001 and June 2006. The most common cause was idiopathic palsy (16 cases, 66.7 per cent). The most common degree of facial nerve paralysis on first presentation was House-Brackmann grade IV (15 of 24 cases). All cases were treated with steroids. One of the 24 cases was also treated surgically with facial nerve decompression. Twenty-two cases (91.6 per cent) recovered to House-Brackmann grade I or II over the six-month follow-up period. Facial nerve paralysis in children can generally be successfully treated with conservative measures. However, in cases associated with trauma, radiological investigation is required for further evaluation and treatment.

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.

Causes and imaging manifestations of paralysis of the recurrent laryngeal nerve.

PubMed

Méndez Garrido, S; Ocete Pérez, R F

The vocal cords play a key role in the functions of the larynx. Their motor innervation depends on the recurrent laryngeal nerve (a branch of the tenth cranial nerve), which follows a long trajectory comprising intracranial, cervical, and mediastinal segments. Vocal cord paralysis usually manifests as dysphonia, the main symptom calling for CT study, the first-line imaging test to investigate the cause of the lesion. Patients are asymptomatic in a third of cases, so the incidental detection of signs of vocal cord paralysis in a CT study done for other reasons should prompt a search for a potentially severe occult lesion. This article aims to familiarize readers with the anatomy of the motor innervation of the glottis, the radiological presentation and most common causes of vocal cord paralysis, and conditions that can simulate vocal cord paralysis.

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.

Evaluate histories, clinical signs, and laboratory data of 69 horses homozygous by DNA testing for hyperkalemic periodic paralysis (HPP). Cohort study. 69 of 189 horses testing homozygous for HPP between October 1992 and November 1994. Questionnaires addressing signalment, training regimes, medical history, and current status of affected horses were sent to owners, trainers, or attending veterinarians. Data from completed questionnaires were tabulated and evaluated, using descriptive statistics. Sixty-nine (37%) of 189 questionnaires were completed and returned. Clinical episodes of muscle weakness or paralysis varied in severity and frequency from mild muscle fasciculations to recumbency and death. Sixty-three of 68 HPP-affected horses were reported to have had stridor associated with exercise, excitement, stress, or episodes of muscle paralysis. Common endoscopic findings in affected horses included pharyngeal collapse, pharyngeal edema, laryngopalatal dislocation, and laryngeal paralysis. Twelve of 27 horses receiving acetazolamide had decreases in stridor while receiving medication. Most horses testing homozygous for HPP had clinical signs associated with pharyngeal and laryngeal dysfunction. Hyperkalemic periodic paralysis should be included on a differential list for horses examined for signs of laryngeal or pharyngeal dysfunction or stridor. Treatment with acetazolamide may help to control respiratory tract signs associated with this disease.

Familial congenital bilateral vocal fold paralysis: a novel gene translocation.

True vocal fold (TVF) paralysis is a common cause of neonatal stridor and airway obstruction, though bilateral TVF paralysis is seen less frequently. Rare cases of familial congenital TVF paralysis have been described with implied genetic origin, but few genetic abnormalities have been discovered to date. The purpose of this study is to describe a novel chromosomal translocation responsible for congenital bilateral TVF immobility. The charts of three patients were retrospectively reviewed: a 35 year-old woman and her two children. The mother had bilateral TVF paralysis at birth requiring tracheotomy. Her oldest child had a similar presentation at birth and also required tracheotomy, while the younger child had laryngomalacia without TVF paralysis. Standard karyotype analysis was done using samples from all three patients and the parents of the mother, to assess whether a chromosomal abnormality was responsible. Karyotype analysis revealed the same balanced translocation between chromosomes 5 and 14, t(5;14) (p15.3, q11.2) in the mother and her two daughters. No other genetic abnormalities were identified. Neither maternal grandparent had the translocation, which appeared to be a spontaneous mutation in the mother with autosomal dominant inheritance and variable penetrance. A novel chromosomal translocation was identified that appears to be responsible for familial congenital bilateral TVF paralysis. While there are other reports of genetic abnormalities responsible for this condition, we believe this is the first describing this particular translocation. Copyright © 2014 Elsevier Ireland Ltd.

BACKGROUND: Facial paralysis is defined as severe or complete loss of facial muscle motor function. OBJECTIVE: The study was undertaken to explore a bibliometric approach to quantitatively assess the research on clinical treatment of facial paralysis using rehabilitation, physiotherapy and acupuncture using Web of Science from 1992 to 2011. DESIGN: Bibliometric approach. DATA RETRIEVAL: A bibliometric analysis based on the publications on Web of Science was performed using key words such as “facial paralysis”, “rehabilitation”, “physiotherapy” and “acupuncture”. INCLUSIVE CRITERIA: (1) Research articles on the clinical treatment of facial paralysis using acupuncture or physiotherapy (e.g. exercise, electro-stimulation) and other rehabilitation methods; (2) researches on human and animal fundamentals, clinical trials and case reports; (3) Article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter. (4) Publication year: 1992–2011 inclusive. Exclusion criteria: (1) Articles on the causes and diagnosis on facial paralysis; (2) Type of articles: correction; (3) Articles from following databases: all databases related to social science and chemical databases in Web of Science. MAIN OUTCOME MEASURES: (1) Overall number of publications; (2) number of publications annually; (3) number of citations received annually; (4) top cited paper; (5) subject categories of publication; (6) the number of countries in which the article is published; (7) distribution of output in journals. RESULTS: Overall population stands at 3 543 research articles addressing the clinical treatment of facial paralysis in Web of Science during the study period. There is also a markedly increase in the number of publications on the subject “facial paralysis treatments using rehabilitation” during the first decade of the 21st century, except in 2004 and 2006 when there are perceptible drops in the number of articles published. The only other year during the study period saw such a drop is 1993. Specifically, there are 192 published articles on facial paralysis treated by rehabilitation in the past two decades, far more than the output of physiotherapy treatment. Physiotherapy treatment scored only 25 articles including acupuncture treatment, with over 80% of these written by Chinese researchers and clinicians. Ranked by regions, USA is by far the most productive country in terms of the number of publications on facial paralysis rehabilitation and physiotherapy research. Seeing from another angle, the journals that focus on otolaryngology published the most number of articles in rehabilitation and physiotherapy studies, whereas most acupuncture studies on facial paralysis were published in the alternative and complementary medicine journals. CONCLUSION: Study of facial paralysis remains an area of active investigation and innovation. Further clinical studies in humans addressing the use of growth factors or stem cells continue to successful facial nerve regeneration. PMID:25767492

Upper airway obstruction due to bilateral vocal cord paralysis presents a serious challenge to the Otolaryngologist. Various surgical techniques have been advocated for the management of patients with vocal cord patients with vocal cord paralysis. Among these techniques, the individual use of laser CO2 arytenoidectomy and posterior cordotomy has gained wide acceptance. In this report, we describe our experience in the management of bilateral vocal cord paralysis by combining posterior partial cordotomy as described by Dennis and Kashima with total arytenoidectomy as described by Ossoff. We report the long term results in the management of 24 patients with bilateral vocal cord paralysis treated in our Department during the last 9 years.

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.

General anesthesia is a safe, frequent procedure in clinical practice. Although it is very unusual in procedures not related to head and or neck surgery, vocal cord paralysis is a serious and important complication. Incidence has been associated with patient age and comorbidities, as well as the position of the endotracheal tube and cuff. It can become a dangerous scenario because it predisposes aspiration. To present a case and analyze the risk factors associated with increased risk of vocal cord paralysis described in the literature. 53 year-old diabetic man, who developed hoarseness in the postoperative period after receiving general anesthesia for an elective abdominal laparoscopic surgery. Otolaryngological evaluation showed left vocal cord paralysis. Vocal cord paralysis can be a serious complication of general anesthesia because of important voice dysfunction and risk of aspiration. The management is not yet fully established, so prevention and early diagnosis is essential. Copyright © 2018 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

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.

periodic paralysis related to hypokalemia is seldom reported in thyrotoxicosis, and it usually occurs in Asian males. Two Romanian (Caucasian) young patients presented with hypokalemic paralysis. TSH, FT4, TT3 was measured by immunochemiluminescence. Case report 1. Patient O.R, aged 19, presented marked asthenia and lower limbs paralysis, following high carbohydrate meal. He declared 10 kg weight loss on hypocaloric diet and mild sweating. Biochemical data revealed moderate hypokalemia (K+=2.6 mmol/L) and thyrotoxicosis (TSH<0.03 mIU/L, FT4=30 pmol/L, TT3=315 ng/dL). Case report 2. Patient T.A., aged 18, presented 2 episodes of weakness and flaccid paralysis, with hypokalemia, precipitated by effort, without any sign of thyrotoxicosis. Biochemical data revealed severe hypokalemia (K+=1.8 mmol/L) and thyrotoxicosis (TSH<0.03 mIU/L, FT4=24 pmol/L, TT3=190 ng/dL). Treatment with intravenous potassium, thereafter methimazole and propranolol were administered in both cases, with the maintenance of normal kalemia and thyrotoxicosis' control. these 2 cases of hypokalemic periodic paralysis occurring in young Caucasian teenagers with mild thyrotoxicosis underlined the importance of thyroid screening in patients with symptomatic hypokalemia, even in the absence of symptoms and signs of thyrotoxicosis.

Immediate post-dosing paralysis following severe soman and VX toxicosis in guinea pigs.

There have been numerous studies of the central nervous system (CNS) involvement in organophosphate (OP) poisoning showing status epilepticus and/or 'electrographic seizures'. Brain damage has been demonstrated as 'neuronal necrosis' primarily in the cortex, thalamus and hippocampus. To the authors' knowledge there have been no reports of partial/total paralysis following close upon OP exposure although delayed paralysis has been reported. This report summarizes the immediate, OP induced paralytic events recorded in guinea pigs during development of the Canadian reactive skin decontaminant lotion (RSDL). As part of the development work, supra-lethal cutaneous doses of OP were applied to large numbers of guinea pigs followed by decontamination with the RSDL or predecessor lotions and solvents. Soman (pinacolyl methylphosphonofluoridate; GD) challenges were applied to 1277 animals and S-(2-diisopropyl-aminoethyl) methylphosphorothiolate (VX) challenges to 108. The classic sequence of clinical signs--ptyalism, tremors, fasciculations, convulsions, apnea and flaccid paralysis before death--was seen in the 658 animals that died and in many of the survivors. Eighty-four of 688 survivors of GD and 4 of 39 survivors of VX showed random paralysis of various distal regions following recovery from an insult which produced convulsions and/or flaccid paralysis. Because the experiments were designed to assess the decontamination procedures, there were no apparent relationships between the amounts of OP applied and the sequellae recorded. The observations of paralysis were also incidental to the prime focus of the experiments. Because of this, only ten animals paralysed following GD exposure were examined for histological effects. The pathologist diagnosed 'encephalomalacia' and 'focal necrotic lesions' in the cerebral cortex and 'focal necrotic lesions' in one spinal cord. Of the 84 guinea pigs paralysed after GD challenge, one was not decontaminated and the decontaminants used on the remainder were sufficiently varied that there appeared to be no relationship between the type of decontaminant and the resulting paralysis. 2005 John Wiley & Sons, Ltd.

Quality of life differences in patients with right- versus left-sided facial paralysis: Universal preference of right-sided human face recognition.

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.

Relations among hypnagogic and hypnopompic experiences associated with sleep paralysis.

PubMed

Cheyne, J A; Newby-Clark, I R; Rueffer, S D

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.

Seventy species of ticks are known from Australia: 14 soft ticks (family Argasidae) and 56 hard ticks (family Ixodidae). Sixteen of the 70 ticks in Australia may feed on humans and domestic animals (Barker and Walker 2014). The other 54 species of ticks in Australia feed only on wild mammals, reptiles and birds. At least 12 of the species of ticks in Australian also occur in Papua New Guinea. We use an image-matching system much like the image-matching systems of field guides to birds and flowers to identify Ixodes holocyclus (paralysis tick), Ixodes cornuatus (southern paralysis tick) and Rhipicephalus (Boophilus) australis (Australian cattle tick). Our species accounts have reviews of the literature on I. holocyclus (paralysis tick) from the first paper on the biology of an Australian tick by Bancroft (1884), on paralysis of dogs by I. holocyclus, to papers published recently, and of I. cornuatus (southern paralysis tick) and Rhipicephalus (Boophilus) australis (Australian cattle tick). We comment on four controversial questions in the evolutionary biology of ticks: (i) were labyrinthodont amphibians in Australia in the Devonian the first hosts of soft, hard and nuttalliellid ticks?; (ii) are the nuttalliellid ticks the sister-group to the hard ticks or the soft ticks?; (iii) is Nuttalliella namaqua the missing link between the soft and hard ticks?; and (iv) the evidence for a lineage of large bodied parasitiform mites (ticks plus the holothyrid mites plus the opiliocarid mites).

To determine if a simple assessment of vocal cord function performed in a routine clinical setting can predict vocal cord paralysis on laryngoscopy in patients following thyroid or parathyroid surgery. Prospective observational cohort study of patients undergoing thyroid or parathyroid surgery. Vocal cord function was assessed in terms of an abnormality of voice or cough reported by the patient or detected by the examiner. Laryngoscopy was performed by indirect mirror examination or fibreoptic nasopharyngolaryngoscopy. Examiners included otolaryngology consultants, registrars, senior house officers and a general practitioner with a special interest in otolaryngology. The patient was often examined by a different clinician before and after surgery. Eighty-six patients participated in the study between August 2003 and July 2004. Eleven had a change in their voice postoperatively and one patient had difficulty coughing. Six of these patients had a vocal cord paralysis. A further five apparently asymptomatic patients had a vocal cord paralysis. The positive predictive value of voice assessment for vocal cord paralysis was 55%. In a routine clinical setting where the assessment of vocal cord function is often reported by different clinicians of varying experience at each patient attendance, the assessment of a patient's voice following thyroid or parathyroid surgery is not adequately predictive of vocal cord paralysis on indirect laryngoscopy or fibreoptic nasopharyngolaryngoscopy. Further study is required to determine reasons for this.

Voice-related quality of life (V-RQOL) following type I thyroplasty for unilateral vocal fold paralysis.

Unilateral vocal fold paralysis is a common clinical problem which frequently causes severe dysphonia. Various treatment options exist for this condition, with the type I thyroplasty being one of the more commonly performed surgical procedures for vocal rehabilitation. The Voice-Related Quality of Life (V-RQOL) Measure is a validated outcomes instrument for voice disorders. This study measured the V-RQOL of patients with unilateral vocal fold paralysis who had undergone a type I thyroplasty and compared these scores to those of patients with untreated and uncompensated unilateral vocal fold paralysis and to normals. Treated patients had significantly higher domain and overall V-RQOL scores than untreated patients, but also scored lower than normals. These differences were true across gender and age. Patients who were more distant from surgery had lower V-RQOL scores than those who had more recently been treated. It is concluded that type I thyroplasty leads to a significantly higher V-RQOL for patients with unilateral vocal fold paralysis. This study also demonstrates further the utility of patient-oriented measures of treatment outcome.

Inappropriate sinus tachycardia (IST) is a rare disorder amenable to catheter ablation when refractory to medical therapy. Radiofrequency (RF) catheter modification/ablation of the sinus node (SN) is the usual approach, although it can be complicated by right phrenic nerve paralysis. We describe a patient with IST, who had symptomatic recurrences despite previous acutely successful RF SN modifications, including the use of electroanatomical mapping/navigation system. We decided to try transvenous cryothermal modification of the SN. We used 2 min applications at -85 degrees C at sites of the earliest atrial activation guided by activation mapping during isoprenaline infusion. Every application was preceded by high output stimulation to reveal phrenic nerve proximity. During the last application, heart rate slowly and persistently fell below 85 bpm despite isoprenaline infusion, but right diaphragmatic paralysis developed. At 6 months follow-up, the patient was asymptomatic and the diaphragmatic paralysis had partially resolved. This is the first report, we believe, of successful SN modification for IST by endocardial cryoablation, although this case also demonstrates the considerable risk of right phrenic nerve paralysis even with this ablation energy.

Hypnotic paralysis has been used since the times of Charcot to study altered states of consciousness; however, the underlying neurobiological correlates are poorly understood. We investigated human brain function during hypnotic paralysis using resting-state functional magnetic resonance imaging (fMRI), focussing on two core regions of the default mode network and the representation of the paralysed hand in the primary motor cortex. Hypnotic suggestion induced an observable left-hand paralysis in 19 participants. Resting-state fMRI at 3T was performed in pseudo-randomised order awake and in the hypnotic condition. Functional connectivity analyses revealed increased connectivity of the precuneus with the right dorsolateral prefrontal cortex, angular gyrus, and a dorsal part of the precuneus. Functional connectivity of the medial frontal cortex and the primary motor cortex remained unchanged. Our results reveal that the precuneus plays a pivotal role during maintenance of an altered state of consciousness. The increased coupling of selective cortical areas with the precuneus supports the concept that hypnotic paralysis may be mediated by a modified representation of the self which impacts motor abilities.

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,more » 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.« less

Diagnosis and management of patients with Bell's palsy.

PubMed

Mooney, Tracy

Bell's palsy (idiopathic facial paralysis) is the most common cause of acute unilateral facial nerve paralysis. Although it is usually a self-limiting condition, it can be distressing for the patient. Many people who experience one-sided facial paralysis fear that it is a symptom of stroke. However, there are subtle differences between Bell's palsy and stroke. This article discusses potential causes of the condition and identifies the differences between Bell's palsy and stroke. In addition, appropriate strategies for the care of patients with the condition are suggested. Management includes antiviral medication, corticosteroid therapy, eye care, botulinum toxin type A injection, physiotherapy, surgery and acupuncture. Psychological and emotional care of these patients is also important because any facial disability caused by facial nerve paralysis can result in anxiety and stress.

We report on the history and clinical findings of an injecting drug abuser in the Canton of Zurich who presented with multiple deep abscesses in the arms and legs. A diagnosis of wound botulism was made based on his clinical presentation with a rapidly progressing descending paralysis starting at the cranial nerves, a neuromuscular junction disorder on neurophysiologic testing, and normal findings on lumbar puncture. Several cases of wound botulism have occurred in i.v. drug abuse in Switzerland since 1997. We suspect subcutaneous injections of contaminated heroin containing Clostridium spores as sites of entry. Wound botulism caused by Clostridium botulinum is a rare cause of rapidly progressing, generalized, flaccid paralysis and should be considered in patients with a history of i.v. drug abuse presenting with descending paralysis.

A flaccid paralysis results from damage to any part of the lower motor neurone, from destruction of the anterior horn cell by poliomyelitis to injury of the peripheral axon by trauma or disease. Reconstructive surgery can do much to alleviate the residual paralysis. The indications and timing for surgery are considered. Certain well-tried operative techniques are described, from tendon transplantation to arthrodeses of joints, and the relative merits of each procedure are evaluated and placed in perspective.

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.

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.

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.

Idiopathic diaphragmatic paralysis: Bell's palsy of the diaphragm?

PubMed

Crausman, Robert S; Summerhill, Eleanor M; McCool, F Dennis

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.

Facial Nerve Paralysis due to Chronic Otitis Media: Prognosis in Restoration of Facial Function after Surgical Intervention

Purpose Facial paralysis is an uncommon but significant complication of chronic otitis media (COM). Surgical eradication of the disease is the most viable way to overcome facial paralysis therefrom. In an effort to guide treatment of this rare complication, we analyzed the prognosis of facial function after surgical treatment. Materials and Methods A total of 3435 patients with COM, who underwent various otologic surgeries throughout a period of 20 years, were analyzed retrospectively. Forty six patients (1.33%) had facial nerve paralysis caused by COM. We analyzed prognostic factors including delay of surgery, the extent of disease, presence or absence of cholesteatoma and the type of surgery affecting surgical outcomes. Results Surgical intervention had a good effect on the restoration of facial function in cases of shorter duration of onset of facial paralysis to surgery and cases of sudden onset, without cholesteatoma. No previous ear surgery and healthy bony labyrinth indicated a good postoperative prognosis. Conclusion COM causing facial paralysis is most frequently due to cholesteatoma and the presence of cholesteatoma decreased the effectiveness of surgical treatment and indicated a poor prognosis after surgery. In our experience, early surgical intervention can be crucial to recovery of facial function. To prevent recurrent cholesteatoma, which leads to local destruction of the facial nerve, complete eradication of the disease in one procedure cannot be overemphasized for the treatment of patients with COM.

To investigate the adverse effects of acupuncture on the prognosis, and effectiveness of acupuncture combined with far infrared ray in the patient of acute Bell's facial paralysis within 48 h. Clinically randomized controlled trial was used, and the patients were divided into 3 groups: group A (early acupuncture group), group B (acupuncture combined with far infrared ray) and group C (acupuncture after 7 days). The facial nerve functional classification at the attack, 7 days after the attack and after treatment, the clinically cured rate of following-up of 6 months, and the average cured time, the cured time of complete facial paralysis were observed in the 3 groups. There were no significant differences among the 3 groups in the facial nerve functional classification 7 days after the attack, the clinically cured rate of following-up of 6 months and the average cured time (P > 0.05), but the cured time of complete facial paralysis in the group A and the group B were shorter than that in the group C (P < 0.05). The patient of acute Bell's facial paralysis can be treated with acupuncture and moxibustion, and traditional moxibustion can be replaced by far infrared way.

Clinical management of microstomia due to the static treatment of facial paralysis and oral rehabilitation with dental implants.

PubMed

Selvi, Firat; Guven, Erdem; Mutlu, Deniz

2011-05-01

Facial-nerve paralysis is seldom seen and may occur because of a broad spectrum of causes. The most commonly seen cause of facial paralysis is the Bell palsy; iatrogenic causes and tumors are relatively rare. Facial asymmetry, drooling, garbled speech, and difficulty in feeding: all adversely affect the psychosocial conditions of the patients. Fascial and tendon sling procedures may be performed for the static treatment of the unilateral permanent facial paralysis. These techniques are used both for the correction of the asymmetry of the face, especially by providing static support for the corner of the mouth, and to prevent drooling. Microstomia after a sling procedure is not a previously observed complication in the literature. A patient is presented with the surgical management of the complication of microstomia that had risen because of a static treatment of his unilateral facial paralysis via a tendon that passes circularly through his orbicularis oris muscle. Oral rehabilitation thereafter was maintained with the support of dental implants and fixed prosthodontics. The most efficient treatment protocol was decided with an interdisciplinary consultation of the oral and maxillofacial surgeon, the plastic surgeon, and the prosthodontist.

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.

Paralyzed by desire: a new type of body integrity identity disorder.

PubMed

2012-03-01

Body incongruity in body integrity identity disorder (BIID) manifests in the desire to have a healthy limb amputated. We describe a variant of the disorder: the desire to become paralyzed (paralysis-BIID). Sixteen otherwise healthy participants, recruited through Internet-based forums, websites, or word of mouth, completed questionnaires about details of their desire and accompanying symptoms. Onset of the desire for paralysis typically preceded puberty. All participants indicated a specific level for desired spinal cord injury. All participants simulated paralysis through mental imagery or physical pretending, and 9 (56%) reported erotic interest in paraplegia and/or disability. Our key new finding was that 37.5% of paralysis-BIID participants were women, compared with 4.4% women in a sample of 68 individuals with amputation-BIID. BIID reflects a disunity between self and body, usually with a prominent sexual component. Sex-related differences are emerging: unlike men, a higher proportion of women desire paralysis than desire amputation, and, while men typically seek unilateral amputation, women typically seek bilateral amputation. We propose that these sex-related differences in BIID manifestation may relate to sex differences in cerebral lateralization, or to disruption of representation and/or processing of body-related information in right-hemisphere frontoparietal networks.

A clinician’s guide to recurrent isolated sleep paralysis

PubMed Central

Sharpless, Brian A

2016-01-01

This review summarizes the empirical and clinical literature on sleep paralysis most relevant to practitioners. During episodes of sleep paralysis, the sufferer awakens to rapid eye movement sleep-based atonia combined with conscious awareness. This is usually a frightening event often accompanied by vivid, waking dreams (ie, hallucinations). When sleep paralysis occurs independently of narcolepsy and other medical conditions, it is termed “isolated” sleep paralysis. Although the more specific diagnostic syndrome of “recurrent isolated sleep paralysis” is a recognized sleep–wake disorder, it is not widely known to nonsleep specialists. This is likely due to the unusual nature of the condition, patient reluctance to disclose episodes for fear of embarrassment, and a lack of training during medical residencies and graduate education. In fact, a growing literature base has accrued on the prevalence, risk factors, and clinical impact of this condition, and a number of assessment instruments are currently available in both self-report and interview formats. After discussing these and providing suggestions for accurate diagnosis, differential diagnosis, and patient selection, the available treatment options are discussed. These consist of both pharmacological and psychotherapeutic interventions which, although promising, require more empirical support and larger, well-controlled trials. PMID:27486325

To identify combined laryngeal paralysis and collapse in small dogs and describe postoperative outcome after arytenoid lateralization. Case series. Small nonbrachycephalic breed dogs with laryngeal paralysis and collapse (n = 6). Medical records of small breed dogs with airway problems and undergoing laryngeal surgery (January-December 2008) were reviewed. Dogs with combined laryngeal paralysis and laryngeal collapse (LPLC) had arytenoid lateralization. The immediate, 4 week and 6 month postoperative outcomes were described. Direct visual laryngeal exam under a light plane of anesthesia revealed bilateral failure of arytenoid and vocal fold movement and concurrent bilateral medial folding with contact of the cuneiform processes in all dogs. None of the dogs had intra- or immediate postoperative complications after arytenoid lateralization. Two dogs required a 2nd contralateral procedure. Follow-up after 6 months revealed marked improvement in clinical signs related to upper airway obstruction, but all dogs continued to have mild respiratory noise. Concurrent laryngeal paralysis and collapse should be considered as part of the differential diagnosis for small, nonbrachycephalic dogs with upper airway disease. Arytenoid lateralization resulted in improvement of clinical signs related to obstructive airway disease. © Copyright 2011 by The American College of Veterinary Surgeons.

Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group. All patients presenting with vocal fold paralysis over a 12-month period were included. Medical charts were revised retrospectively. The diagnosis was performed by flexible endoscopic examination. The cases were evaluated with respect to aetiology of the paralysis, presenting symptoms, delay in diagnosis, affected side, vocal fold position, need for surgical treatment and outcome. The presenting symptoms were stridor and dysphonia. Iatrogenic causes formed the largest group, followed by idiopathic, neurological and obstetric VFP. Unilateral paralysis was found in most cases. The median value for delay in diagnosis was 1 month and it was significantly higher in the iatrogenic group. Surgical treatment was not necessary in most part of cases. The diagnosis of VFP may be suspected based on the patient's symptoms and confirmed by flexible endoscopy. Infants who develop stridor or dysphonia following a surgical procedure have to be examined without delay. The surgeon has to keep in mind that there is a possibility of late spontaneous recovery or compensation. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Bilateral simultaneous facial paralysis is an extremely rare clinical entity. Unlike the unilateral form, bilateral facial paralysis seldom falls into Bell's category. It is most often a special finding in a symptom complex of a systemic disease; many of them are potentially life-threatening, and therefore the condition warrants urgent medical intervention. Lyme disease, Guillian-Barre syndrome, Bell's palsy, leukemia, sarcoidosis, bacterial meningitis, syphilis, leprosy, Moebius syndrome, infectious mononucleosis, and skull fracture are the most common cause of bilateral facial paralysis. Here we present a 16-year-old patient with bilateral simultaneous Bell's palsy.

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. 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. 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. 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 characterization and analysis in order to determine their association with clinical presentation of a case.

2015-01-01

Summary: Facial nerve paralysis because of penetrating trauma through the external auditory canal is extremely rare, with a paucity of published literature. The objective of this study is to review the literature on transtympanic facial nerve paralysis and increase physician awareness of this uncommon injury through discussion of its clinical presentation, management and prognosis. We also aim to improve patient outcomes in those that have sustained this type of injury by suggesting an optimal management plan. In this case report, we present the case of a 46-year-old white woman who sustained a unilateral facial nerve paresis because of a garfish penetrating her tympanic membrane and causing direct damage to the tympanic portion of her facial nerve. On follow-up after 12 months, her facial nerve function has largely returned to normal. Transtympanic facial nerve paralysis is a rare injury but can have a favorable prognosis if managed effectively. PMID:26090278

Needle electromyography is an important tool in the diagnosis of neuromuscular diseases and has also been applied successfully in the evaluation of the vocal cord paralysis. Laryngeal electromyography, initially described by Weddell, is used to determine the cause of vocal cord paralysis and to differentiate organic from nonorganic causes of speech disorders. This test allows the diagnosis of lower motor neuron and nerve paralysis as well as myopathies. Laryngeal electromyography also helps to determine the prognosis of paralysis caused by traumatic injury of the laryngeal nerves and is used for guidance during botulinum toxin injection in spasmodic dysphonias. Single fiber electromyography is used to diagnose abnormalities of neuromuscular transmission and is applied in the study the architecture of the motor unit in muscles. This article reviews the techniques of laryngeal muscles single fiber electromyography, provides limited informative data, and discusses its potential value in the evaluation of patients with dysphonia.

Metastatic tumors to the temporal bone are very rare. The most common sites of origin of temporal bone metastases are breast, lung, kidney, gastrointestinal tract, larynx, prostate gland, and thyroid gland. The pathogenesis of spread to the temporal bone is most commonly by the hematogenous route. The common otologic symptoms that manifest with facial nerve paralysis are often thought to be due to a mastoid infection. Here is a report on a case of breast carcinoma presenting with otalgia, otorrhea, and facial paralysis for 2 months. The patient was initially diagnosed as mastoiditis, and later the clinical impression was revised to metastatic breast carcinoma to temporal bone, based on the pathologic findings. Metastatic disease should be considered as a possible etiology in patients with a clinical history of malignant neoplasms presenting with common otologic or vestibular symptoms, especially with facial nerve paralysis.

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. PMID:22267521

Paralysis as a Presenting Symptom of Hyperthyroidism in an Active Duty Soldier.

Jennette, John; Tauferner, Dustin

2015-01-01

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.

ABSTRACT 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. PMID:25063199

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

Thornton, Matthew D

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.

Diagnosis of unilateral diaphragmatic paralysis in dogs is currently based on fluoroscopic detection of unequal movement between the crura. Bilateral paralysis may be more difficult to confirm with fluoroscopy because diaphragmatic movement is sometimes produced by compensatory abdominal muscle contractions. The purpose of this study was to develop a new method to evaluate diaphragmatic movement using M-mode ultrasonography and to describe findings for normal and diaphragmatic paralyzed dogs. Fifty-five clinically normal dogs and two dogs with diaphragmatic paralysis were recruited. Thoracic radiographs were acquired for all dogs and fluoroscopy studies were also acquired for clinically affected dogs. Two observers independently measured diaphragmatic direction of motion and amplitude of excursion using M-mode ultrasonography for dogs meeting study inclusion criteria. Eight of the clinically normal dogs were excluded due to abnormal thoracic radiographic findings. For the remaining normal dogs, the lower limit values of diaphragmatic excursion were 2.85-2.98 mm during normal breathing. One dog with bilateral diaphragmatic paralysis showed paradoxical movement of both crura at the end of inspiration. One dog with unilateral diaphragmatic paralysis had diaphragmatic excursion values of 2.00 ± 0.42 mm on the left side and 4.05 ± 1.48 mm on the right side. The difference between left and right diaphragmatic excursion values was 55%. Findings indicated that M-mode ultrasonography is a relatively simple and objective method for measuring diaphragmatic movement in dogs. Future studies are needed in a larger number of dogs with diaphragmatic paralysis to determine the diagnostic sensitivity of this promising new technique. © 2013 American College of Veterinary Radiology.

To induce experimental peripheral facial paralysis by inoculation of HSV1 and to compare the effects of steroid, acyclovir, lipoprostoglandin E2 and steroid + acyclovir treatments in terms of clinical recovery, electrophysiologically and histopathologically. A total of 132 adult female rats were used in this study. HSV type 1 strain was inoculated at the back of the left ear by using 27 gauge needle. Of all animals, 70 (53%) rats which developed facial paralysis were divided into five groups (n = 14 for each group) as control, steroid + acyclovir, lipoprostaglandin E1, steroid only and acyclovir only. At the end of the 21 days period, the rats were clinically examined and electrophysiological tests were performed, then decapitated and the nerve specimens were obtained. A modified electroneurography (ENoG) test was performed and the latencies and the amplitudes were compared. The findings of the intact side were better, but with no significant difference. Histopathologicaly edema was significantly smaller in all groups compared to the controls (p < 0.05). Similarly, no difference was seen in terms of vacuolar degeneration and Schwann cell hyperchromatisation among the groups and no significant difference in recovery period and rate of facial paralysis when all groups were compared. Facial paralysis induced by HSV1 recovered spontaneously within a week. In the treatment of facial paralysis, steroid alone, acyclovir alone, steroid + acyclovir, or lipoprostaglandin E1 all reduced edema in the infected facial nerve but there was no statistical difference in of the rate or degree of recovery.

Masseteric-facial nerve transposition for reanimation of the smile in incomplete facial paralysis.

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.

Dahlmann, W; Volles, E; Lüderitz, B

1977-10-28

A 39-year-old woman developed generalised paralysis, reversible organic brain syndrome, and cardiac dysrhythmias after 15 years of laxative abuse. Under continuous and cautious administration of potassium the cardiac rhythm became normal within four days and two days later the paralysis and organic brain syndrome almost disappeared. The cause of the psychiatric symptoms is thought to be cerebral potassium deficiency and an abnormal sodium/potassium equilibrium. Other clinical signs and symptoms due to extreme potassium depletion are presented. The importance of Na+/K+-activated membrane ATP-ase in myocardium and CNS is discussed.

Laryngeal electromyography is used in the evaluation of vocal cord paralysis to confirm the diagnosis, to guide the diagnostic work-up for etiology, to provide prognostic information and to help choose the correct treatment for the patient. Cardiovocal syndrome is characterised by vocal cord paralysis due to a cardiovascular disease. A wide spectrum of conditions can result in this syndrome. Here we present a case of cardiovocal syndrome in association with primary pulmonary hypertension. Laryngeal electromyography was used to guide the work-up of differential diagnosis and also for further intervention with respect to vocal cord paralysis in this patient.

Carbonic anhydrase II (CAII) deficiency is an autosomal recessive disorder manifest by osteopetrosis, renal tubular acidosis, and cerebral calcification. Other features include growth failure and mental retardation. Complications of the osteopetrosis include frequent bone fractures, cranial nerve compression, and dental mal-occlusion. A hyper-chloremic metabolic acidosis, sometimes with hypokalemia, occurs due to renal tubular acidosis that may be proximal, distal, or more commonly, the combined type. Such patients may present with global hypotonia, muscle weakness or paralysis. We report a case of CA II deficiency with recurrent attacks of acute paralysis which was misdiagnosed initially as Guillian-Barre syndrome.

After reviewing this article, the participant should be able to: 1. Understand the most modern indications and technique for neurotization, including masseter-to-facial nerve transfer (fifth-to-seventh cranial nerve transfer). 2. Contrast the advantages and limitations associated with contiguous muscle transfers and free-muscle transfers for facial reanimation. 3. Understand the indications for a two-stage and one-stage free gracilis muscle transfer for facial reanimation. 4. Apply nonsurgical adjuvant treatments for acute facial nerve paralysis. Facial expression is a complex neuromotor and psychomotor process that is disrupted in patients with facial paralysis breaking the link between emotion and physical expression. Contemporary reconstructive options are being implemented in patients with facial paralysis. While static procedures provide facial symmetry at rest, true 'facial reanimation' requires restoration of facial movement. Contemporary treatment options include neurotization procedures (a new motor nerve is used to restore innervation to a viable muscle), contiguous regional muscle transfer (most commonly temporalis muscle transfer), microsurgical free muscle transfer, and nonsurgical adjuvants used to balance facial symmetry. Each approach has advantages and disadvantages along with ongoing controversies and should be individualized for each patient. Treatments for patients with facial paralysis continue to evolve in order to restore the complex psychomotor process of facial expression.

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.

This is a retrospective study. The objective of this study is to review the factors influencing the outcome of treatment for the patients presented with idiopathic facial nerve paralysis. The demographic data, clinical presentation and management of 84 patients with idiopathic facial nerve paralysis (Bell's palsy) were collected from the medical record office, reviewed and analyzed from 2000 to 2005. Thirty-four (72.3%) out of 47 patients who were treated with oral prednisolone alone, fully recovered from Bell's palsy meanwhile 36 (97%) out of 37 patients who were treated with combination of oral prednisolone and acyclovir fully recovered. The difference was statistically significant. 42 (93.3%) out of 45 patients who presented within three days to our clinic, fully recovered while 28 (71.8%) out of 39 patients presented later then three days had full recovery from Bell's palsy. The difference was statistically significant. The outcome of full recovery is better with the patients treated with combined acyclovir and prednisolone compared with prednisolone alone. The patients who were treated after three days of clinical presentation, who were more than 50 years of age, who had concurrent chronic medical illness and facial nerve paralysis HB Grade IV to VI during initial presentation have reduced chance of full recovery of facial nerve paralysis.

The purpose of this study was to assess clinical and neurophysiological changes after 6 mos of transcutaneous electrical stimulation in patients with unresolved facial nerve paralysis. A pilot case series of 10 consecutive patients with chronic facial nerve paralysis either of idiopathic origin or because of herpes zoster oticus participated in this open study. All patients received below sensory threshold transcutaneous electrical stimulation for 6 mos for their facial nerve paralysis. The intervention consisted of gradually increasing the duration of electrical stimulation of three sites on the affected area for up to 6 hrs/day. Assessments of the facial nerve function were performed using the House-Brackmann clinical scale and neurophysiological measurements of compound motor action potential distal latencies on the affected and nonaffected sides. Patients were tested before and after the intervention. A significant improvement was observed in the facial nerve upper branch compound motor action potential distal latency on the affected side in all patients. An improvement of one grade in House-Brackmann scale was observed and some patients also reported subjective improvement. Transcutaneous electrical stimulation treatment may have a positive effect on unresolved facial nerve paralysis. This study illustrates a possibly effective treatment option for patients with the chronic facial paresis with no other expectations of recovery.

Evidence indicates that neuroinflammation contributes to motor neuron degeneration in amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease leading to progressive muscular paralysis. However, it remains elusive whether inflammatory cells can interact with degenerating distal motor axons, influencing the progressive denervation of neuromuscular junctions (NMJs). By analyzing the muscle extensor digitorum longus (EDL) following paralysis onset in the SOD1G93A rat model, we have observed a massive infiltration and degranulation of mast cells, starting after paralysis onset and correlating with progressive NMJ denervation. Remarkably, mast cells accumulated around degenerating motor axons and NMJs, and were also associated with macrophages. Mast cell accumulation and degranulation in paralytic EDL muscle was prevented by systemic treatment over 15 days with masitinib, a tyrosine kinase inhibitor currently in clinical trials for ALS exhibiting pharmacological activity affecting mast cells and microglia. Masitinib-induced mast cell reduction resulted in a 35% decrease in NMJ denervation and reduced motor deficits as compared with vehicle-treated rats. Masitinib also normalized macrophage infiltration, as well as regressive changes in Schwann cells and capillary networks observed in advanced paralysis. These findings provide evidence for mast cell contribution to distal axonopathy and paralysis progression in ALS, a mechanism that can be therapeutically targeted by masitinib. PMID:29046475

The management of peripheral facial nerve palsy: "paresis" versus "paralysis" and sources of ambiguity in study designs.

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, independent of the treatment regimen. In the Bell's paralysis group, 38 patients (70%) recovered completely after 1 year, including 94% of patients with a denervation by ENoG of less than 90%. Thirty percent of Bell's paralysis patients recovered incompletely, revealing the worst outcome in patients with a 100% denervation on ENoG. None of the 4 patients with HZO and ENoG denervation of more than 90% recovered to normal facial function. We found a highly significant difference regarding the time course and final outcome in patients with incomplete palsies versus total paralysis; however, only 3 of 250 studies make this distinction. The time course for improvement and the extent of recovery is significantly different in patients presenting with an incomplete facial nerve paresis compared with patients with a total paralysis. Whereas the term "palsy" includes both entities, the term "paralysis" should only be used to describe total loss of nerve function. Patients with incomplete acute Bell's palsy (paresis) should start to improve their facial function early (1-2 wk after onset) and are expected to recover completely within 3 months. These patients do not benefit from antiviral medications and most likely do not profit from systemic steroids. Mixing patients with different severity of palsies will always lead to controversial results.

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.

Objectives Population-level incidence of vocal fold paralysis after thyroidectomy for well-differentiated thyroid carcinoma (WDTC) is not known. This study aimed to measure longitudinal incidence of post-operative vocal fold paralyses and need for directed interventions in the Medicare population undergoing total thyroidectomy for WDTC. Study Design Retrospective Cohort Study Setting United States Population Subjects Medicare Beneficiaries Methods SEER-Medicare data (1991 – 2009) were used to identify beneficiaries who underwent total thyroidectomy for WDTC. Incident vocal fold paralyses and directed interventions were identified. Multivariate analyses were used to determine factors associated with odds of developing these surgical complications. Results Of 5,670 total thyroidectomies for WDTC, 9.5% were complicated by vocal fold paralysis [8.2% unilateral vocal fold paralysis (UVFP); 1.3% bilateral vocal fold paralysis (BVFP)]. Rate of paralyses decreased 5% annually from 1991 to 2009 (OR 0.95, 95% CI 0.93 – 0.97; p<0.001). Overall, 22% of patients with vocal fold paralysis required surgical intervention (UVFP 21%, BVFP 28%). Multivariate logistic regression revealed odds of post-thyroidectomy paralysis increased with each additional year of age, with non-Caucasian race, particular histologic types, advanced stage, and in particular registry regions. Conclusions Annual rates of post-thyroidectomy vocal fold paralyses are decreasing among Medicare beneficiaries with WDTC. High incidence in this aged population is likely due to a preponderance of temporary paralyses, which is supported by the need for directed intervention in less than a quarter of affected patients. Further population-based studies are needed to refine the population incidence and risk factors for paralyses in the aging population. PMID:24482349

There are many patient-based and clinician-based scales measuring the severity of facial nerve paralysis and the impact on quality of life, however, the social perception of facial palsy has received little attention. The purpose of this pilot study was to measure the consequences of facial paralysis on selected domains of social perception and compare the social impact of paralysis of the different components. Four patients with typical facial palsies (global, marginal mandibular, zygomatic/buccal, and frontal) and 1 control were photographed. These images were each shown to 100 participants who subsequently rated variables of normality, perceived distress, trustworthiness, intelligence, interaction, symmetry, and disability. Statistical analysis was performed to compare the results among each palsy. Paralyzed faces were considered less normal compared to the control on a scale of 0 to 10 (mean, 8.6; 95% confidence interval [CI] = 8.30-8.86) with global paralysis (mean, 3.4; 95% CI = 3.08-3.80) rated as the most disfiguring, followed by the zygomatic/buccal (mean, 6.0; 95% CI = 5.68-6.37), marginal (mean, 6.5; 95% CI = 6.08-6.86), and then temporal palsies (mean, 6.9; 95% CI = 6.57-7.21). Similar trends were seen when analyzing these palsies for perceived distress, intelligence, and trustworthiness, using a random effects regression model. Our sample suggests that society views paralyzed faces as less normal, less trustworthy, and more distressed. Different components of facial paralysis are worse than others and surgical correction may need to be prioritized in an evidence-based manner with social morbidity in mind. © 2016 Wiley Periodicals, Inc.

To present the pathologic characteristics of unilateral recurrent nerve adductor branch paralysis (AdBP), and to investigate the management of posterior cricoarytenoid (PCA) muscle on the basis of our experience of surgical treatment for AdBP. This is a retrospective review of clinical records Four cases of AdBP, in which surgical treatment was performed, are presented. AdBP shows disorders of vocal fold adduction because of paralysis of the thyroarytenoid and lateral cricoarytenoid muscles. The PCA muscle, dominated by the recurrent nerve PCA muscle branch, does not show paralysis. Thus, this type of partial recurrent nerve paresis retains the abductive function and is difficult to distinguish from arytenoid cartilage dislocation because of their similar endoscopic findings. The features include acute onset, and all cases were idiopathic etiology. Thyroarytenoid muscle paralysis was determined by electromyography and stroboscopic findings. The adduction and abduction of paralytic arytenoids were evaluated from 3 dimensional computed tomography (3DCT). In all cases, surgical treatments were arytenoid adduction combined with thyroplasty. When we adducted the arytenoid cartilage during inspiration, strong resistance was observed. In the two cases where we could cut the PCA muscle sufficiently, the maximum phonation time was improved to ≥30 seconds after surgery, from 2 to 3 seconds preoperatively, providing good postoperative voices. In contrast, in the two cases of insufficient resection, the surgical outcomes were poorer. Because the preoperative voice in AdBP patients is typically very coarse, surgical treatment is needed, as well as ordinary recurrent nerve paralysis. In our experience, adequate PCA muscle resection might be helpful in surgical treatment of AdBP. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

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.

Background Cardiac surgery – associated iatrogenic laryngeal trauma is often overlooked. We investigated the risk factors of vocal cord paralysis in cardiac surgery. Methods Medical records were reviewed from 169 patients who underwent elective or emergency cardiac surgeries. Patients had transesophageal echocardiography (TEE) placed either under video fiberscopic image guidance (guided group) or blind placement (blind group). Routine postoperative otolaryngologist consultation with video laryngoscopic recording were performed. Results Vocal cord paralyses were found in 18 patients (10.7%; left-13, right-4, bilateral-1). The risk of vocal cord paralysis was associated with emergency operation [odds ratio, 97.5 (95% confidence interval [CI], 2.9 to 366), p = 0.01]. Use of fiberscope-guided TEE [odds ratio, 0.04 (95% CI 0.01 to 0.87), p = 0.04] can effectively reduce vocal cord injury. Conclusions Emergency cardiac surgery increased the risk of vocal cord paralysis. Fiberscope-guided TEE placement is recommended for all patients having cardiac surgery to decrease the risk of severe peri-operative laryngeal trauma. PMID:29167615

Vocal cord paralysis (VCP) is found in both benign and malignant thyroid disease. This study was performed to determine if the presence of preoperative VCP predicts malignancy. A retrospective analysis was performed on a cohort of 1923 consecutive patients undergoing thyroid surgery. The incidence of preoperative VCP was recorded. Patient and nodule characteristics were correlated with final pathology. 1.3% of our cohort was found to have preoperative VCP. Malignant pathology was discovered in 76% of patients with preoperative VCP. Among these patients, 72% had a left sided paralysis. 10.5% of patients with preoperative VCP had perineural invasion (PNI) on final pathology, compared to 1.1% of patients with normal VC function. Preoperative VCP appears to be a strong, though not an absolute, indicator of malignancy. Most VCP were on the left side. Assessing for preoperative VCP is crucial in all patients who need thyroid surgery, as even benign nodules can be accompanied by preoperative vocal cord paralysis.

The effectiveness of laryngeal reinnervation by anza cervicalis abduction in the treatment of unilateral vocal fold paralysis in thyroid surgery was study. The prospectively examined 11 patients with abduction paralysis of the larynx, which were treated by ipsilateral anastomosis of anza cervicalis main branch to the distal stump of the recurrent laryngeal nerve were performed. The survey was conducted on the pre- and postoperative stages and included videolaryngoscopy, acoustic analysis, and patient self-assessment of voice. Average follow-up was (2.98 +/- 1.04) years. The use of videolaryngoscopy showed significant improvement of the spatial positioning of the vocal folds in the postoperative period and acoustical parameters. Laryngeal reinnervation by anza cervicalis is an effective treatment for laryngeal paralysis related to operations on the thyroid gland and laryngeal function can be improve to almost normal of the spoken voice parameters and the basic functions of the larynx.

Bone loss can result from bed rest, space flight, spinal cord injury or age-related hormonal changes. Current bone loss mitigation techniques include pharmaceutical interventions, exercise, pulsed ultrasound targeted to bone and whole body vibration. In this study, we attempted to mitigate paralysis-induced bone loss by applying focused ultrasound to the midbelly of a paralyzed muscle. We employed a mouse model of disuse that uses onabotulinumtoxinA-induced paralysis, which causes rapid bone loss in 5 d. A focused 2 MHz transducer applied pulsed exposures with pulse repetition frequency mimicking that of motor neuron firing during walking (80 Hz), standing (20 Hz), or the standard pulsed ultrasound frequency used in fracture healing (1 kHz). Exposures were applied daily to calf muscle for 4 consecutive d. Trabecular bone changes were characterized using micro-computed tomography. Our results indicated that application of certain focused pulsed ultrasound parameters was able to mitigate some of the paralysis-induced bone loss. PMID:24857416

Hypokalemic Paralysis Complicated by Concurrent Hyperthyroidism and Hyperaldosternoism: A Case Report

2017-01-01

Patient: Female, 38 Final Diagnosis: Primary hyperaldosteronism Symptoms: Paralysis Medication: — Clinical Procedure: — Specialty: Nephrology Objective: Challenging differential diagnosis 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 hyper-thyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease. PMID:28050008

Thyrotoxic periodic paralysis (TPP) is a condition characterised by muscle paralysis due to hypokalaemia usually secondary to thyrotoxicosis. We report a case of a 31-year-old man with no known comorbidities who presented to a tertiary healthcare unit with a 1-month history of difficulty in breathing, palpitations, weight loss and hoarseness of voice. On examination, his thyroid gland was palpable and fine hand tremors were present. An initial provisional diagnosis of hyperthyroidism was made. Three months after initial presentation, the patient presented in emergency with severe muscle pain and inability to stand. Laboratory results revealed hypokalaemia. All the symptoms reverted over the next few hours on administration of intravenous potassium. A diagnosis of TTP was established. After initial presentation, the patient was treated with carbimazole and propranolol. Once he was euthyroid, radioactive iodine ablation therapy (15 mCi) was carried out as definitive therapy, after which the patient's symptoms resolved; he is currently doing fine on levothyroxine replacement and there has been no recurrence of muscle paralysis. 2015 BMJ Publishing Group Ltd.

Multi-channel orbicularis oculi stimulation to restore eye-blink function in facial paralysis.

Facial paralysis due to facial nerve injury results in the loss of function of the muscles of the hemiface. The most serious complication in extreme cases is the loss of vision. In this study, we compared the effectiveness of single- and multiple-channel electrical stimulation to restore a complete and cosmetically acceptable eye blink. We established bilateral orbicularis oculi muscle (OOM) paralysis in eight dogs; the OOM of one side was directly stimulated using single-channel electrical stimulation and the opposite side was stimulated using multi-channel electrical stimulation. The changes in the palpebral fissure and complete palpebral closure were measured. The difference in current intensities between the multi-channel and single-channel simulation groups was significant, while only multi-channel stimulation produced complete eyelid closure. The latest electronic stimulation circuitry with high-quality implantable electrodes will make it possible to regulate precisely OOM contractions and thus generate complete and cosmetically acceptable eye-blink motion in patients with facial paralysis.

Bell palsy is an acute facial paralysis of unknown etiology. Although recovery from Bell palsy is expected without intervention, clinical experience suggests that recovery is often incomplete. This case report describes a classification system used to guide treatment and to monitor recovery of an individual with facial paralysis. The patient was a 71-year-old woman with complete left facial paralysis secondary to Bell palsy. Signs and symptoms were assessed using a standardized measure of facial impairment (Facial Grading System [FGS]) and questions regarding functional limitations. A treatment-based category was assigned based on signs and symptoms. Rehabilitation involved muscle re-education exercises tailored to the treatment-based category. In 14 physical therapy sessions over 13 months, the patient had improved facial impairments (initial FGS score= 17/100, final FGS score= 68/100) and no reported functional limitations. Recovery from Bell palsy can be a complicated and lengthy process. The use of a classification system may help simplify the rehabilitation process.

Neuro-proprioceptive facilitation in the re-education of functional problems in facial paralysis. A practical approach.

Sardaru, D; Pendefunda, L

2013-01-01

Facial paralysis, in the form of Bell's syndrome, is an acute paralysis of idiopathic origin. Disability in patients with this medical condition is the result of impairment or loss of complex and multidimensional functions of the face like emotion expression through facial mimics, facial identity and communication. This study aimed to present new and improved practical manual techniques in the area of facial neuromuscular facilitations and to review the literature for disability indexes and facial nerve grading. We present the practical modality of using neuro-proprioceptive facilitation techniques, such as rhythmic initiation, repeated stretch (repeated contractions), combination of isotonics and percussion, and also report the effects of these techniques in three Bell's syndrome patients which were previously evaluated. Recovery from facial paralysis can be a difficult and long lasting process and the utilization of a grading system may help the physical therapist. The effects of this type of therapy may help_benefit the patient if the therapist is well trained and familiar with the neurophysiological background.

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

PubMed

Fukuda, K

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.

The aim of this study was to describe the association between landscape and climate factors and the occurrence of tick paralysis cases in dogs and cats reported by veterinarians in Australia. Data were collated based on postcode of residence of the animal and the corresponding landscape (landcover and elevation) and climate (precipitation, temperature) information was derived. During the study period (October 2010-December 2012), a total of 5560 cases (4235 [76%] canine and 1325 [24%] feline cases) were reported from 341 postcodes, mostly along the eastern seaboard of Australia and from the states of New South Wales and Queensland. Significantly more cases were reported from postcodes which contained areas of broadleaved, evergreen tree coverage (P=0.0019); broadleaved, deciduous open tree coverage (P=0.0416); and water bodies (P=0.0394). Significantly fewer tick paralysis cases were reported from postcodes which contained areas of sparse herbaceous or sparse shrub coverage (P=0.0297) and areas that were cultivated and managed (P=0.0005). No significant (P=0.6998) correlation between number of tick paralysis cases reported per postcode and elevation was found. Strong positive correlations were found between number of cases reported per postcode and the annual minimum (rSP=0.9552, P<0.0001) and maximum (rSP=0.9075; P=0.0001) precipitation. Correlations between reported tick paralysis cases and temperature variables were much weaker than for precipitation, rSP<0.23. For maximum temperature, the strongest correlation between cases was found in winter (rSP=0.1877; P=0.0005) and for minimum temperature in autumn (rSP=0.2289: P<0.0001). Study findings suggest that tick paralysis cases are more likely to occur and be reported in certain eco-climatic zones, such as those with higher rainfall and containing tree cover and areas of water. Veterinarians and pet owners in these zones should be particularly alert for tick paralysis cases to maximize the benefits of early treatment, and to be vigilant to use chemical prophylaxis to reduce the risk of tick parasitism.

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 characterization and analysis in order to determine their association with clinical presentation of a case. PMID:17300736

The authors present a case of suspected malpractice linked to the onset of hemidiaphragm paralysis after robot-assisted radical prostatectomy (RARP). The approach to the case is shown from a medico-legal point of view. It is demonstrated how, after a thorough review of the literature, this was not a case of medical malpractice but an unforeseeable event. This paper aims at contributing to the very few reports dealing with the onset of hemidiaphragm paralysis after RARP, thus fostering clinical knowledge of these rare events and meanwhile providing useful data for the medico-legal handling in case of alleged negligence of surgeons. © 2015 S.

Patients infected with West Nile virus (WNV) may develop acute neurologic disease, which can be severe or even fatal, including WNV meningitis, encephalitis, and an irreversible acute flaccid paralysis or poliomyelitis-like syndrome. Movement disorders have also been described. We report combined neuronal loss, gliosis, and neurofibrillary tangle formation in the substantia nigra of a 41-year-old man with a history of WNV encephalomyelitis and poliomyelitis-like paralysis. Clinically our patient did not display parkinsonism, however, it is interesting to speculate whether, in the absence of the residual subacute poliomyelitis-like syndrome, the neuropathologic findings could have eventually evolved clinically into WNV-associated postencephalitic parkinsonism.

Mice with an NaV1.4 sodium channel null allele have latent myasthenia, without susceptibility to periodic paralysis

PubMed Central

Wu, Fenfen; Mi, Wentao; Fu, Yu; Struyk, Arie

2016-01-01

Over 60 mutations of SCN4A encoding the NaV1.4 sodium channel of skeletal muscle have been identified in patients with myotonia, periodic paralysis, myasthenia, or congenital myopathy. Most mutations are missense with gain-of-function defects that cause susceptibility to myotonia or periodic paralysis. Loss-of-function from enhanced inactivation or null alleles is rare and has been associated with myasthenia and congenital myopathy, while a mix of loss and gain of function changes has an uncertain relation to hypokalaemic periodic paralysis. To better define the functional consequences for a loss-of-function, we generated NaV1.4 null mice by deletion of exon 12. Heterozygous null mice have latent myasthenia and a right shift of the force-stimulus relation, without evidence of periodic paralysis. Sodium current density was half that of wild-type muscle and no compensation by retained expression of the foetal NaV1.5 isoform was detected. Mice null for NaV1.4 did not survive beyond the second postnatal day. This mouse model shows remarkable preservation of muscle function and viability for haploinsufficiency of NaV1.4, as has been reported in humans, with a propensity for pseudo-myasthenia caused by a marginal Na+ current density to support sustained high-frequency action potentials in muscle.

Although many factors have been found to be involved in recovery from Bell's palsy, no study has investigated the association between recovery from Bell's palsy and obesity. This study therefore evaluated the association between recovery from Bell's palsy and body mass index (BMI). Subjects were classified into five groups based on BMI (kg/m 2 ). Demographic and clinical characteristics were compared among these groups. Assessed factors included sex, age, time from paralysis to visiting a hospital, the presence of comorbidities such as diabetes mellitus and hypertension, degree of initial facial nerve paralysis by House-Brackmann (H-B) grade and neurophysiological testing, and final recovery rate. Based on BMI, 37 subjects were classified as underweight, 169 as normal weight, 140 as overweight, 155 as obese and 42 as severely obese. Classification of the degree of initial facial nerve paralysis as moderate or severe, according to H-B grade and electroneurography, showed no difference in severity of initial facial paralysis among the five groups (P > 0.05). However, the final recovery rate was significantly higher in the normal weight than in the underweight or obese group (P < 0.05). Obesity or underweight had no effect on the severity of initial facial paralysis, but the final recovery rate was lower in the obese and underweight groups than in the normal group. © 2016 John Wiley & Sons Ltd.

Background Lower extremity paralysis continues to complicate aortic interventions. The lack of understanding of the underlying pathology has hindered advancements to decrease the occurrence this injury. The current model demonstrates reproducible lower extremity paralysis following thoracic aortic occlusion. Methods Adult male C57BL6 mice were anesthetized with isoflurane. Through a cervicosternal incision the aorta was exposed. The descending thoracic aorta and left subclavian arteries were identified without entrance into pleural space. Skeletonization of these arteries was followed by immediate closure (Sham) or occlusion for 4 min (moderate ischemia) or 8 min (prolonged ischemia). The sternotomy and skin were closed and the mouse was transferred to warming bed for recovery.  Following recovery, functional analysis was obtained at 12 hr intervals until 48 hr. Results Mice that underwent sham surgery showed no observable hind limb deficit. Mice subjected to moderate ischemia for 4 min had minimal functional deficit at 12 hr followed by progression to complete paralysis at 48 hr. Mice subjected to prolonged ischemia had an immediate paralysis with no observable hind-limb movement at any point in the postoperative period. There was no observed intraoperative or post operative mortality. Conclusion Reproducible lower extremity paralysis whether immediate or delayed can be achieved in a murine model. Additionally, by using a median sternotomy and careful dissection, high survival rates, and reproducibility can be achieved. PMID:24637534

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.

2014-01-01

Laryngeal framework surgery is the current gold standard treatment for unilateral vocal fold paralysis. It provides a permanent solution to glottic insufficiency caused by injury to the recurrent laryngeal nerve. Various modifications to the original Isshiki type I laryngoplasty procedure have been described to improve voice and swallowing outcomes. The success of this procedure is highly dependent on the experience of the surgeon as it epitomizes the intersection of art and science in the field. The following article reviews the evidence, controversies, and complications related to laryngoplasty for unilateral vocal fold paralysis. It also provides a detailed analysis of how and when arytenoid-positioning procedures should be considered, and summarizes the literature on postoperative outcomes. PMID:24883239

Herbal and dietary supplements for weight loss and in treatment of obesity are growing in popularity and acceptance in the United States. Most of these supplements can be obtained over the counter and can have serious adverse effects associated with their consumption. We describe 2 patients who developed thyrotoxic hypokalemic periodic paralysis 2-3 weeks after consuming thyroxine-containing weight-loss supplements. This is the first known case of thyrotoxic hypokalemic periodic paralysis secondary to dietary supplements. It is important that patients and physicians are aware of the severe adverse reactions associated with dietary supplements. Physicians should as a routine inquire about herbal and dietary supplement consumption during all patient encounters.

Avian tick paralysis caused by Ixodes brunneus in the southeastern United States

1996-01-01

Between 1988 and 1994, 16 definitive and 26 presumptive cases of tick paralysis were diagnosed in 10 species of birds from five southeastern states in the USA. All birds had engorged adult female Ixodes brunneus ticks on the head region and were partially paralyzed or dead. Cases occurred in the winter and early spring months, and most birds were passerines found in private yards or near feeders. All stages of I. brunneus feed exclusively on birds, and this species previously has been associated with avian tick paralysis. Little is known concerning the life cycle of this ixodid tick and its impact on wild bird populations.

A 3-year-old male presented with Chlamydia pneumoniae infection-related hemophagocytic lymphohistiocytosis (HLH). The patient developed an episode of HLH with severe skin eruption following C. pneumoniae pneumonia. Symptoms responded to steroid/cyclosporine A therapy, but the patient slowly lost consciousness and developed systemic flaccid paralysis. He was diagnosed with encephalitis/myelitis by brain and spinal MRI. Neurological symptoms and signs gradually resolved. We thought that the immune response to C. pneumoniae infection triggered the development of HLH, associated with unusual neurological complications. This report describes a novel case of C. pneumoniae-associated HLH and with poliomyelitis like flaccid paralysis. Copyright © 2010 Wiley-Liss, Inc.

Rotifer neuropharmacology--III. Adrenergic drug effects on Brachionus plicatilis.

PubMed

Keshmirian, J; Nogrady, T

1987-01-01

Norepinephrine (NE) induces three pharmacological effects in Brachionus plicatilis. As a result of excitation the rate of ciliary motion and swimming increases, and the animals flip their foot constantly at a rapid rate. This rapid foot flipping was used as a specific model to measure adrenergic effects in B. plicatilis. Phenylephrine induces the same effect at identical efficacy, while isoproterenol and salbutamol, two beta-agonists, show one-half and one-tenth NE efficacy. The beta blocker propranolol and the alpha blocker tolazoline both antagonize foot flipping induced by NE. However, propranolol shows antagonism because it causes foot paralysis by itself. Timolol, another beta blocker but without the membrane effect of propranolol, does not antagonize the alpha receptor mediated NE effect, nor does it cause foot paralysis. Propranolol, timolol and tolazoline also show agonist activity, inducing foot flipping. NE does not antagonize the foot paralysis induced by propranolol, only its anesthetic effect by delaying its onset. These results indicate that the foot flipping induced by NE is a receptor-mediated alpha adrenergic effect, while the foot paralysis is caused by membrane phenomena.

Quantitative analysis of facial paralysis using local binary patterns in biomedical videos.

PubMed

He, Shu; Soraghan, John J; O'Reilly, Brian F; Xing, Dongshan

2009-07-01

Facial paralysis is the loss of voluntary muscle movement of one side of the face. A quantitative, objective, and reliable assessment system would be an invaluable tool for clinicians treating patients with this condition. This paper presents a novel framework for objective measurement of facial paralysis. The motion information in the horizontal and vertical directions and the appearance features on the apex frames are extracted based on the local binary patterns (LBPs) on the temporal-spatial domain in each facial region. These features are temporally and spatially enhanced by the application of novel block processing schemes. A multiresolution extension of uniform LBP is proposed to efficiently combine the micropatterns and large-scale patterns into a feature vector. The symmetry of facial movements is measured by the resistor-average distance (RAD) between LBP features extracted from the two sides of the face. Support vector machine is applied to provide quantitative evaluation of facial paralysis based on the House-Brackmann (H-B) scale. The proposed method is validated by experiments with 197 subject videos, which demonstrates its accuracy and efficiency.

Minimally invasive brow suspension for facial paralysis.

Costantino, Peter D; Hiltzik, David H; Moche, Jason; Preminger, Aviva

2003-01-01

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.

Studies of intercellular invasion in vitro using rabbit peritoneal neutrophil granulocytes (PMNS). I. Role of contact inhibition of locomotion

PubMed Central

1975-01-01

Intercellular invasion is the active migration of cells on one type into the interiors of tissues composed of cells of dissimilar cell types. Contact paralysis of locomotion is the cessation of forward extension of the pseudopods of a cell as a result of its collision with another cell. One hypothesis to account for intercellular invasion proposes that a necessary condition for a cell type to be invasive to a given host tissue is that it lack contact paralysis of locomotion during collision with cells of that host tissue. The hypothesis has been tested using rabbit peritoneal neutrophil granulocytes (PMNs) as the invasive cell type and chick embryo fibroblasts as the host tissue. In organ culture, PMNs rapidly invade aggregates of fibroblasts. The behavior of the pseudopods of PMNs during collision with fibroblasts was analyzed for contact paralysis by a study of time-lapse films of cells in mixed monolayer culture. In monolayer culture, PMNs show little sign of paralysis of the pseudopods upon collision with fibroblasts and thus conform in their behavior to that predicted by the hypothesis. PMID:1092702

The madness of Dionysus -- six hypotheses on the illness of Nietzsche.

Tényi, Tamás

2012-01-01

Friedrich Nietzsche (1844-1900) is considered as one of the most influential modern thinkers of the last two centuries. The great philosopher and poet developed a mental illness at the age of 44 and died at the age of 56. Pathological examination was not undertaken. At that time Nietzsche was diagnosed as having atypical paralysis progressiva, however recently five other probable diagnoses appeared in literature. Literature search in MEDLINE and Web of Science on the illness of Nietzsche. Six hypotheses were identified: 1. Paralysis progressiva (General paralysis of the insane) 2. Bipolar affective disorder followed by vascular dementia 3. Hereditary form of frontotemporal dementia 4. Brain tumor 5. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) 6. Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) syndrome. Developments in neurology and molecular genetics give new perspectives to the secret of Nietzsche's illness and also there is a consensus on the questioning of the original paralysis progressiva concept. As there was no postmortem, the clinical speculations on the medical problems of the great philosopher remain a challenge.

The 66 serotypes of human enteroviruses (EVs) are classified into four species A-D, based on phylogenetic relationships in multiple genome regions. Partial VP(1) amplification and sequence analysis are reliable methods for identifying non-polio enterovirus serotypes, especially in negative cell culture specimens from patients with residual paralysis. In Iran during the years 2000-2002, there were 29 residual paralysis cases with negative cell (RD, HEp(2) and L(20)B) culture results. The genomic RNA was extracted from stool specimens from cases of residual paralysis and detected by amplification of the 5'-nontranslated region using RT-PCR with Pan-EV primers. Partial VP(1) amplification by semi-nested RT-PCR (snRT-PCR) and sequence analysis were done. Specimens from the 29 culture-negative cases contained echoviruses of six different serotypes. The global eradication of wild polioviruses is near and study of non-polio enteroviruses, which can cause poliomyelitis, is increasingly important to understand their pathogenesis. The VP(1) sequences, derived from the snRT-PCR products, allowed rapid molecular analysis of these non-polio strains.

2016-10-01

Bilateral facial palsy is a rare clinical entity caused by myriad disparate conditions requiring different treatment paradigms. Lyme disease, Guillain-Barré syndrome, and leukemia are several examples. In this article, the authors describe the cause, the initial diagnostic approach, and the management of long-term sequelae of bilateral paralysis that has evolved in the authors' center over the past 13 years. A chart review was performed to identify all patients diagnosed with bilateral paralysis at the authors' center between January of 2002 and January of 2015. Demographics, signs and symptoms, diagnosis, initial medical treatment, interventions for facial reanimation, and outcomes were reviewed. Of the 2471 patients seen at the authors' center, 68 patients (3 percent) with bilateral facial paralysis were identified. Ten patients (15 percent) presented with bilateral facial paralysis caused by Lyme disease, nine (13 percent) with Möbius syndrome, nine (13 percent) with neurofibromatosis type 2, five (7 percent) with bilateral facial palsy caused by brain tumor, four (6 percent) with Melkersson-Rosenthal syndrome, three (4 percent) with bilateral temporal bone fractures, two (3 percent) with Guillain-Barré syndrome, one (2 percent) with central nervous system lymphoma, one (2 percent) with human immunodeficiency virus infection, and 24 (35 percent) with presumed Bell palsy. Treatment included pharmacologic therapy, physical therapy, chemodenervation, and surgical interventions. Bilateral facial palsy is a rare medical condition, and treatment often requires a multidisciplinary approach. The authors outline diagnostic and therapeutic algorithms of a tertiary care center to provide clinicians with a systematic approach to managing these complicated patients.

Experience with developmental facial paralysis: part II. Outcomes of reconstruction.

Terzis, Julia K; Anesti, Katerina

2012-01-01

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 < 0.001, Kruskal-Wallis test) and the electrophysiologic data (p < 0.0001). The improvement in eye closure, smile, and depressor function was greater in children as compared with adults (p < 0.005, Mann-Whitney test). Early targeted screening and diagnosis, with prompt specialized treatment, improves the physical and emotional development of 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.

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 cope with the considerable emotional and social consequences. Recognizing the psychosocial dimensions of disease allows clinicians to communicate more effectively, be more empathetic, and to better personalize treatment plans, which may lead to improved patient care and patient satisfaction.

Hypoglossal-facial nerve "side"-to-side neurorrhaphy for facial paralysis resulting from closed temporal bone fractures.

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 regrowth in a rich supportive environment.

Surgical Interventions for Pediatric Unilateral Vocal Cord Paralysis: A Systematic Review.

2015-07-01

The most widely used surgical interventions for pediatric unilateral vocal cord paralysis include injection laryngoplasty, thyroplasty, and laryngeal reinnervation. Despite increasing interest in surgical interventions for unilateral vocal cord paralysis in children, the surgical outcomes data in children are scarce. To appraise and summarize the available evidence for pediatric unilateral vocal cord paralysis surgical strategies. MEDLINE (1946-2014) and EMBASE (1980-2014) were searched for publications that described the results of laryngoplasty, thyroplasty, or laryngeal reinnervation for pediatric unilateral vocal cord paralysis. Further studies were identified from bibliographies of relevant studies, gray literature, and annual scientific assemblies. Two reviewers independently appraised the selected studies for quality, level of evidence, and risk of bias as well as extracted data, including unilateral vocal cord paralysis origin, voice outcomes, swallowing outcomes, and adverse events. Of 366 identified studies, the inclusion criteria were met by 15 studies: 6 observational studies, 6 case series, and 3 case reports. All 36 children undergoing laryngeal reinnervation (8 studies) had improvement or resolution of dysphonia. Of 31 children receiving injection laryngoplasty (6 studies), most experienced improvement in voice quality, speech, swallowing, aspiration, and glottic closure. Of 12 children treated by thyroplasty (5 studies), 2 experienced resolution of dysphonia, 4 had some improvement, and 4 had no improvement (2 patients had undocumented outcomes). Thyroplasty resolved or improved aspiration in 7 of 8 patients. Published studies suggest that reinnervation may be the most effective surgical intervention for children with dysphonia; however, long-term follow-up data are lacking. With the exception of polytetrafluoroethylene injections, injection laryngoplasty was reported to be a relatively safe, nonpermanent, and effective option for most children with dysphonia. Thyroplasty appears to have fallen out favor in recent years because of difficulty in performing this procedure in children under local anesthesia, but it continues to be a viable option for children with aspiration.

An initial assessment method that can classify as well as categorize the severity of paralysis into one of six levels according to the House-Brackmann (HB) system based on facial landmarks motion using an Optical Flow (OF) algorithm is proposed. The desired landmarks were obtained from the video recordings of 5 normal and 3 Bell's Palsy subjects and tracked using the Kanade-Lucas-Tomasi (KLT) method. A new scoring system based on the motion analysis using area measurement is proposed. This scoring system uses the individual scores from the facial exercises and grades the paralysis based on the HB system. The proposed method has obtained promising results and may play a pivotal role towards improved rehabilitation programs for patients.

A case of isolated abducens nerve paralysis in maxillofacial trauma

2015-01-01

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.

The timber rattlesnake, also known as Crotalus horridus, is well known to cause significant injury from toxins stored within its venom. During envenomation, toxic systemic effects immediately begin to cause damage to many organ systems including cardiovascular, hematologic, musculoskeletal, respiratory, and neurologic. One defining characteristic of the timber rattlesnake is a specific neurotoxin called crotoxin, or the "canebrake toxin," which is a potent β-neurotoxin affecting presynaptic nerves that can cause paralysis by inhibiting appropriate neuromuscular transmission. We present an unusual case of an 8-year-old boy bitten twice on his calf by a timber rattlesnake, who presented with a life-threatening envenomation and suffered multisystem organ failure as well as a prominent presynaptic neurotoxicity resulting in facial diplegia, pharyngeal paralysis, and ophthalmoplegia.

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.

1988-03-01

Paralysis of Angora goat kids caused by adult ticks, which most probably belong to an undescribed species of the Rhipicephalus pravus group, is described. Confirmed cases of paralysis occurred in the south-western Orange Free State between the second half of September and the first half of November as well as during the first half of February. The mean female tick burdens (mean = 21.4) of paralysed Angora kids were significantly higher than those of healthy kids (mean = 4.4). The predilection attachment site of the adult ticks was the ears of the goats. The elephant shrew Elephantulus myurus is a preferred host of the immature stages whereas the scrub hare Lepus saxatilis serves as an important host for the adult ticks.

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

PubMed

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.

Guillain-Barré is a rare, autoimmune disease of the peripheral nervous system. It can affect all ages beginning in the intrauterine or neonatal period. Clinical forms are diverse and include acute motor axonal neuropathy (AMAN). We report on a pediatric case of AMAN. A 2.5-year-old child presented with acute flaccid paralysis and preserved reflexes. Etiologic investigations argued in favor of Guillain-Barré syndrome in its AMAN form. Treatment based on IV immunoglobulins resulted in a total decline of paralysis and motor recovery. The AMAN form of Guillain-Barré syndrome should be considered as a potential diagnosis in all cases of acute flaccid paralysis with preserved reflexes. Copyright © 2016 Elsevier Masson SAS.

Sleep paralysis and folklore

PubMed Central

2015-01-01

Sleep paralysis is a relatively new term to describe what for hundreds of years many believed to be a visitation by a malevolent creature which attacked its victims as they slept. The first clinical description of sleep paralysis was published in 1664 in a Dutch physician’s case histories, where it was referred to as, ‘Incubus or the Night-Mare [sic]’. In 1977, it was discovered more than 100 previously healthy people from various South East Asian communities had died mysteriously in their sleep. The individuals affected were dying at a rate of 92/100,000 from Sudden Unexplained Nocturnal Death Syndrome. No underlying cause was ever found, only that subsequent studies revealed a high rate of sleep paralysis and belief in the dab tsog (nightmare spirit) amongst members of the community. The nightmare/succubus is descended from Lilith. The earliest reference to Lilith is found in the Sumerian King list of 2400 BC known as Lilitu or she-demon, she bore children from her nocturnal unions with men. In other derivations, she was Adam’s first wife who rather than ‘obey’ became a demon that preyed on women during childbirth. In modern Middle Eastern maternity wards, some women still wear amulets for protection. Today, clinical cause of these disturbances is sleep paralysis due to the unsuitable timing of REM sleep. During the ‘Nightmare’ episode, the sleeper becomes partially conscious during REM cycle, leaving the individual in a state between dream and wakefulness. For some, culture and the tradition of the nightmare is explanation enough. PMID:28008370

Wasp venom blocks central cholinergic synapses to induce transient paralysis in cockroach prey.

PubMed

Haspel, G; Libersat, F

2003-03-01

The parasitoid wasp Ampulex compressa induces a set of unique behavioral effects upon stinging its prey, the cockroach. It stings into the first thoracic segment inducing 2 to 3 min of transient flaccid paralysis of the front legs. This facilitates a second sting in the cockroach's head that induces 30 min of excessive grooming followed by a 2 to 5-week long lethargic state. In the present study, we examine the immediate effect of the first sting, which is a transient paralysis of the front legs. Using radiolabeled wasps, we demonstrate that the wasp injects its venom directly into the cockroach's first thoracic ganglion. The artificial injection of milked venom into a thoracic ganglion abolishes spontaneous and evoked responses of the motoneurons associated with leg movements. To investigate the physiological mechanism of action of the venom, we injected venom into the last abdominal ganglion of the cockroach, which houses a well-characterized cholinergic synapse. Injected venom abolishes both sensory-evoked and agonist-evoked postsynaptic potentials recorded in the postsynaptic neuron for 2 to 3 min without affecting action potential propagation. Thus, the venom blocking effect has a postsynaptic component that follows the same time course as the transient paralysis induced by the thoracic sting. Finally, injection of a nicotinic antagonist in the front thoracic ganglion induces paralysis of the front legs. We conclude that the transient paralytic effect of the thoracic sting can be mainly accounted for by the presence of a venom active component that induces a postsynaptic block of central cholinergic synaptic transmission.

Melkersson-Rosenthal syndrome (MRS) is a rare disorder of unknown cause. The classical triad of MRS is orofacial edema, recurrent facial paralysis, and a fissured tongue. We present a 9-year-old girl with a recurrent peripheral facial paralysis. She experienced the first episode of a peripheral facial paralysis on the same side without orofacial swelling and lingua plicata 1 year ago. She was diagnosed with Hashimoto thyroiditis 9 months earlier, as confirmed by an endocrinologic investigation. While the patient was hospitalized with recurrent facial paralysis, we found that serum levels of free thyroxine (1.3 ng/dL) and thyrotropin (0.4 uIU/mL) were within normal range, but the level of antithyroperoxidase antibodies (772.0 IU/mL) was very increased. She had been taking an oral prednisolone orally for 2 weeks. At the 1-month follow-up, the patient's symptoms had completely disappeared. The possible correlation between MRS and autoimmune disorders has been documented in only one report, which described an adult with autoimmune thyroiditis (Hashimoto thyroiditis) and MRS. We suggest that the co-occurrence of MRS and Hashimoto thyroiditis is not coincidental but linked to autoimmunity. Copyright © 2014 Elsevier Inc. All rights reserved.

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.

Parasitoid wasp sting: a cocktail of GABA, taurine, and beta-alanine opens chloride channels for central synaptic block and transient paralysis of a cockroach host.

PubMed

Moore, Eugene L; Haspel, Gal; Libersat, Frederic; Adams, Michael E

2006-07-01

The wasp Ampulex compressa injects venom directly into the prothoracic ganglion of its cockroach host to induce a transient paralysis of the front legs. To identify the biochemical basis for this paralysis, we separated venom components according to molecular size and tested fractions for inhibition of synaptic transmission at the cockroach cercal-giant synapse. Only fractions in the low molecular weight range (<2 kDa) caused synaptic block. Dabsylation of venom components and analysis by HPLC and MALDI-TOF-MS revealed high levels of GABA (25 mM), and its receptor agonists beta-alanine (18 mM), and taurine (9 mM) in the active fractions. Each component produces transient block of synaptic transmission at the cercal-giant synapse and block of efferent motor output from the prothoracic ganglion, which mimics effects produced by injection of whole venom. Whole venom evokes picrotoxin-sensitive chloride currents in cockroach central neurons, consistent with a GABAergic action. Together these data demonstrate that Ampulex utilizes GABAergic chloride channel activation as a strategy for central synaptic block to induce transient and focal leg paralysis in its host.

2011-07-01

Unilateral diaphragmatic paralysis was diagnosed in 2 preterm neonates born at 29 and 25 weeks of gestation, respectively. In both instances, the pathophysiology was phrenic nerve injury after extravasation of parenteral nutrition fluid. Misplacement and infection were predisposing factors. Diaphragmatic movement analysis by time-motion-mode ultrasonography was helpful in achieving a diagnosis. The first neonate required a diaphragmatic placation, whereas the other infant was managed nonoperatively. These cases confirm a rare etiology of diaphragmatic paralysis and possible spontaneous recovery. In neonates with very low birth weight, general anesthesia and thoracic surgery may be associated with a high morbidity, suggesting that nonoperative medical treatment, when possible, is preferable if the neonate does not require supplemental oxygen.

Takeda, Kotaro; Tanino, Genichi; Miyasaka, Hiroyuki

2017-01-01

Neuromuscular electrical stimulation (NMES), specifically functional electrical stimulation (FES) that compensates for voluntary motion, and therapeutic electrical stimulation (TES) aimed at muscle strengthening and recovery from paralysis are widely used in stroke rehabilitation. The electrical stimulation of muscle contraction should be synchronized with intended motion to restore paralysis. Therefore, NMES devices, which monitor electromyogram (EMG) or electroencephalogram (EEG) changes with motor intention and use them as a trigger, have been developed. Devices that modify the current intensity of NMES, based on EMG or EEG, have also been proposed. Given the diversity in devices and stimulation methods of NMES, the aim of the current review was to introduce some commercial FES and TES devices and application methods, which depend on the condition of the patient with stroke, including the degree of paralysis.

Peripheral facial nerve palsy (Bell' palsy, BP) is a not rare diseases in children, being the most common acquired mononeuropathy. The authors of this study wanted to determine whether the occurrence and course of paralysis changed in the past 5 years (2010-2014). The study involved Lesser Poland region, where the majority of children with paralysis are hospitalized at the Pediatric Neurology Department of University Children's Hospital in Krakow. These children in subsequent years were admitted to our department without any limitations. A review of clinical documentation of 125 patients, in terms of demographics, the coexistence of other diseases, seasonality, the degree of paralysis, location of paralysis, the prevalence of the recurrence was made. Changes in the structure of the nerve VII in MRI and CT, pharmacological treatment, applied rehabilitation, the degree of improvement and time of hospitalization were analyzed. Similar distribution of occurrence and gender of children with BP in Lesser Poland region within 5 years were observed. The predominance of the girls resulted from demographic composition of the population. BP occurred most frequently in summer and winter. In more than half of children BP occurred in the course of acute systemic infection or craniofacial infection and in 5/125 BP followed head injury. Children with infections required antibiotic therapy. Left-sided paralysis was found in the majority of children and almost half of patients needed protection of the cornea of the eye (significant degree). In 12% of children structural changes within the facial nerve were found. In these children antiviral treatment was used and hospitalization time was more than 20 days while in the majority of children hospitalization lasted 15 days. In 8 (6.4%) children with recurrent BP kinezytherapy, electrical stimulation and laser therapy were applied. Steroid therapy was not used. Only 7/125 chil. dren had mild impairment of the eye closing at the discharge and the others received nearly complete recovery. Inflammatory etiology is the most common in children with BP. BP occurs more often in the summer and winter. Severity of paralysis was significant in more than half of hospitalized children. Children with structural changes within the nerve VII required longer hospitalization and comprehensive treatment.

Four-Dimensional CT of the Diaphragm in Children: Initial Experience

PubMed Central

2018-01-01

Objective To evaluate the technical feasibility of four-dimensional (4D) CT for the functional evaluation of the pediatric diaphragm. Materials and Methods In 22 consecutive children (median age 3.5 months, age range 3 days–3 years), 4D CT was performed to assess diaphragm motion. Diaphragm abnormalities were qualitatively evaluated and diaphragm motion was quantitatively measured on 4D CT. Lung density changes between peak inspiration and expiration were measured in the basal lung parenchyma. The diaphragm motions and lung density changes measured on 4D CT were compared between various diaphragm conditions. In 11 of the 22 children, chest sonography was available for comparison. Results Four-dimensional CT demonstrated normal diaphragm (n = 8), paralysis (n = 10), eventration (n = 3), and diffusely decreased motion (n = 1). Chest sonography demonstrated normal diaphragm (n = 2), paralysis (n = 6), eventration (n = 2), and right pleural effusion (n = 1). The sonographic findings were concordant with the 4D CT findings in 90.9% (10/11) of the patients. In diaphragm paralysis, the affected diaphragm motion was significantly decreased compared with the contralateral normal diaphragm motion (−1.1 ± 2.2 mm vs. 7.6 ± 3.8 mm, p = 0.005). The normal diaphragms showed significantly greater motion than the paralyzed diaphragms (4.5 ± 2.1 mm vs. −1.1 ± 2.2 mm, p < 0.0001), while the normal diaphragm motion was significantly smaller than the motion of the contralateral normal diaphragm in paralysis (4.5 ± 2.1 mm vs. 7.6 ± 3.8 mm, p = 0.01). Basal lung density change of the affected side was significantly smaller than that of the contralateral side in diaphragm paralysis (89 ± 73 Hounsfield units [HU] vs. 180 ± 71 HU, p = 0.03), while no significant differences were found between the normal diaphragms and the paralyzed diaphragms (136 ± 66 HU vs. 89 ± 73 HU, p = 0.1) or between the normal diaphragms and the contralateral normal diaphragms in paralysis (136 ± 66 HU vs. 180 ± 71 HU, p = 0.1). Conclusion The functional evaluation of the pediatric diaphragm is feasible with 4D CT in select children. PMID:29354007

The purpose of this study was to determine through measurement of cardiac biomarkers whether there was cardiac involvement in dogs infested with Ixodes holocyclus. Dogs with tick paralysis and no-mild (group 1; n = 44) or moderate-severe respiratory compromise (group 2; n = 36) and a control group of dogs (n = 31) were enrolled. Plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP), serum cardiac troponin I (cTnI) and serum creatinine concentrations were determined. For most of the affected dogs SpO2 was determined. SpO2 readings did not differ between groups 1 and 2. Three animals in group 2 had an SpO2 reading <90%. NT-proBNP concentrations were lower in both groups 1 and 2 compared with the control group. There was no difference in cTnI concentrations among groups, although they were elevated in four dogs, including the three dogs in group 2 with SpO2 readings <90%. Creatinine concentrations were within the reference interval for all dogs, but did differ among the groups, with control dogs having the highest values, followed by group 1 and then group 2. This study did not detect significant cardiac involvement in dogs with tick paralysis induced by I. holocyclus. Evidence for reduced preload in dogs with tick paralysis was provided by lower NT-proBNP concentrations compared with control dogs. Severe hypoxaemia may not be a significant component of the clinical picture in many of the dogs presenting with tick paralysis. Dogs with severe hypoxaemia may have loss of cardiomyocyte integrity, reflected by elevated cTnI concentrations. © 2016 Australian Veterinary Association.

Acute unilateral facial paralysis, such as occurs in Bell palsy and Hunt syndrome, is mostly a benign neurologic morbidity that resolves within a few months. However, incomplete or misdirected return of the affected nerve results in unfavorable cosmetic sequelae in some patients. Although functional problems such as lagophthalmos are rare, facial asymmetry on smiling resulting from a lack of mimetic muscle strength in the cheek is often psychologically annoying to patients. To obtain a more natural smile, the authors transfer latissimus dorsi muscle to assist in cheek movement. A small, thinned muscle (mini-latissimus dorsi) is sufficient for transplant in this situation. In this study, 96 patients with incomplete facial paralysis who underwent mini-latissimus dorsi transfer were examined. In this series, along with evaluation using the grading scale used in previous reports, preoperative and postoperative videos of 30 patients were analyzed for quantitative assessment using newly developed computer software. Temporary deterioration of paralysis was recognized in three cases but did not last more than a few months. Signs of transferred muscle contraction were recorded after 4 to 12 months among 91 patients. No apparent clinical signs of contraction were recognized in one patient, and four patients could not be followed postoperatively. The synchronized ratio of vertical movement and the symmetrical ratio of horizontal movement both in the cheek and in the lower lip between healthy and paralyzed sides among 30 patients were statistically improved. Statistical analysis using newly developed computer software revealed that a more symmetrical smile can be achieved by muscle transfer among patients with incomplete facial paralysis. Mini-latissimus dorsi transfer can avoid postoperative muscle bulkiness of the cheek and can achieve more natural cheek movement.

Little is known about the long-term health related quality of life outcomes in patients with West Nile virus associated acute flaccid paralysis. We describe the quality of life scores of seven patients with acute flaccid paralysis who presented to hospital between 2003 and 2006, and were followed for up to two years. Between 2003 and 2006, 157 symptomatic patients with West Nile virus were enrolled in a longitudinal cohort study of West Nile virus in Canada. Seven patients (4%) had acute flaccid paralysis. The first patient was a 55-year-old man who presented with left upper extremity weakness. The second patient was a 54-year-old man who presented with bilateral upper extremity weakness. The third patient was a 66-year-old woman who developed bilateral upper and lower extremity weakness. The fourth patient was a 67-year-old man who presented with right lower extremity weakness. The fifth patient was a 60-year-old woman who developed bilateral lower extremity weakness. The sixth patient was a 71-year-old man with a history of Parkinson's disease and acute onset bilateral lower extremity weakness. The seventh patient was a 52-year-old man who presented with right lower extremity weakness. All were Caucasian. Patients were followed for a mean of 1.1 years. At the end of follow-up the mean score on the Physical Component Summary of the Short-Form 36 scale had only slightly increased to 39. In contrast, mean score on the Mental Component Summary of the Short-Form 36 scale at the end of follow-up had normalized to 50. Despite the poor physical prognosis for patients with acute flaccid paralysis, the mental health outcomes are generally favorable.

This study aimed to assess the value of comprehensive laboratory evaluation in patients with vocal fold paralysis or paresis. This is a retrospective chart review. Records of 231 patients with vocal fold paralysis or paresis were reviewed to determine whether there is a significant increase in the number of abnormal test results compared with rates of abnormal results for these tests in the general population and whether testing resulted in clinically important diagnosis. Laboratory data were collected from charts from initial visits from 2010 to 2014 and compared with national data. When controlled for age and sex, white blood cell count was found to have a significantly higher rate of abnormal test results (P < 0.001) in patients with vocal fold paralysis or paresis than the general population. Although hemoglobin, thyroid-stimulating hormone, and thyroid antibody tests were more likely to be abnormal in our patient population, the trend was not statistically significant. Further, the prevalence of syphilis and myasthenia gravis was found to be higher in these subjects than their respective national prevalences, and the incidence of Lyme disease was found to be higher than the national prevalence of Lyme disease. Several patients were diagnosed with medically important conditions such as diabetes, thyroid dysfunction, syphilis, myasthenia gravis, and Lyme disease based on these tests. This study suggests that comprehensive testing of patients with vocal fold movement disorders results in diagnoses that would be missed without a comprehensive evaluation, some of which are important medically, although their causal relationship to vocal fold paralysis or paresis was not investigated or established.

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.

ABSTRACT Periodic paralyses (PPs) are rare neuromuscular disorders caused by mutations in skeletal muscle sodium, calcium, and potassium channel genes. PPs include hypokalemic paralysis, hyperkalemic paralysis, and Andersen‐Tawil syndrome. Common features of PP include autosomal dominant inheritance, onset typically in the first or second decades, episodic attacks of flaccid weakness, which are often triggered by diet or rest after exercise. Diagnosis is based on the characteristic clinic presentation then confirmed by genetic testing. In the absence of an identified genetic mutation, documented low or high potassium levels during attacks or a decrement on long exercise testing support diagnosis. The treatment approach should include both management of acute attacks and prevention of attacks. Treatments include behavioral interventions directed at avoidance of triggers, modification of potassium levels, diuretics, and carbonic anhydrase inhibitors.

2017-01-04

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.

Facial nerve paralysis in children

2015-01-01

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.

In 1992 surveillance of acute flaccid paralysis (AFP) cases was introduced in Malaysia along with the establishment of a national referral laboratory at the Institute for Medical Research. The objective of this study was to determine the incidence, viral etiology and clinical picture of AFP cases below 15 years of age, reported from 2002 to 2007. Six hundred seventy-eight of 688 reported cases were confirmed as AFP by expert review. The clinical presentation of acute flaccid paralysis in these cases was diverse, the most commonly reported being Guillian-Barre syndrome (32.3%). Sixty-nine viruses were isolated in this study. They were Sabin poliovirus (25), Echovirus (22), Cocksackie B (11), EV71 (5), Cocksackie A (1), and untypable (5). Malaysia has been confirmed as free from wild polio since the surveillance was established.

Forty-seven patients were analyzed. The mean pre-post-operative rima glottis areas were 1.11 ± 0.56 and 2.24 ± 0.93 mm(2), respectively (p < 0.001). Five patients with previous tracheotomy were decannulated within a few days after the operation. In three patients, mild complications developed in the early post-operative period (two laryngeal edemas, one submucosal hematoma). Tracheotomy was performed to only one pregnant patient in the post-operative first day. None of the patients had granulation formation or synechia.

The etiology of vocal cord paralysis (VCP) is varied. There is lack of consensus regarding the choice of investigations to be used in the evaluation of VCP. The aim of this study was to establish the etiology, assess the diagnostic methods used in the evaluation, and outline an algorithm for future evaluation of unilateral vocal cord paralysis (UVCP). Charts of all patients (n = 94) with the diagnostic code of VCP were reviewed, and reexaminations were performed of patients in whom no etiology was found after the initial symptoms. The etiology of UVCP was neoplasm in 34%, surgical trauma in 12%, and miscellaneous causes in 54%. The etiology of bilateral vocal cord paralysis (BVCP) was neoplasm in 24%, surgical trauma in 24%, and miscellaneous causes in 52%. The reexaminations did not reveal any cancer diseases in the patients concerned. The most effective diagnostic method was CT-scanning while the least effective was thyroid scanning. Because cancer is a common cause of VCP a thorough evaluation is necessary. For UVCP we recommend history and physical examination, X-ray of the chest, ultrasonography of the neck, and CT-scanning of the superior mediastinum. If these prove negative, panendoscopy should be performed. Workup of patients with idiopathic VCP should include examination, X-ray of the chest at 6-month intervals, and annual CT-scanning for two years.

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.

Periodic paralysis: An unusual presentation of drug-induced hyperkalemia.

Hyperkalemia is a life-threatening electrolyte abnormality. The most common cause of hyperkalemia includes renal disease and ingestion of medications. Drug-induced hyperkalemia may develop in patients with underlying renal impairment, disturbed cellular uptake of potassium load, excessive ingestion or infusion of potassium-containing substances. We report a case of "drug-induced severe hyperkalemia" presenting as periodic paralysis. A 67-year-old diabetic and hypertensive woman presented to emergency department with the complaint of intermittent episode of inability to walk for the past 5 days. Each episode lasted for 15-20 minutes and was associated with breathlessness and restlessness. There was no family history of periodic paralysis and drug history revealed that the patient was onolmesartan 20 mg per day (for past 2 years), perindopril 4 mg per day (for past 16 months), and torsemide 10 mg/day. On examination patient was found to be conscious, alert, and afebrile. Vitals were normal. Examination of cardiovascular and respiratory system did not reveal any significant finding. Blood report of the patient showed serum K+ level 8.6 mmol/l. All other investigations were within normal limits. A diagnosis of drug-induced hyperkalemia was made. Patient responded well to the symptomatic treatment. To the best of the author's knowledge, this is the first case report of drug-induced hyperkalemia presenting as periodic paralysis.

Wasp manipulates cockroach behavior by injecting venom cocktail into prey central nervous system.

PubMed

Haspel, G; Libersat, F

2004-01-01

The parasitoid wasp Ampulex compressa induces behavioral changes in the cockroach prey by injecting venom into its central nervous system. In contrast to most other venomous predators, the wasp's sting does not induce paralysis. Rather, the two consecutive stings in the thoracic and head ganglia induce three stereotypic behavioral effects. The prey behavior is manipulated in a way beneficial to the wasp and its offspring by providing a living meal for its newborn larva. The first sting in the thorax causes a transient front leg paralysis lasting a few minutes. This paralysis prevents the cockroach from fighting with its front legs, thereby facilitating the second sting in the head. A postsynaptic block of central synaptic transmission mediates this leg paralysis. Following the head sting, dopamine identified in the venom induces 30 minutes of intense grooming that appears to prevent the cockroach from straying until the last and third behavioral effect of hypokinesia commences. In this lethargic state that lasts about three weeks, the cockroach does not respond to various stimuli nor does it initiates movement. However, other specific behaviors of the prey are unaffected. We propose that the venom represses the activity of head ganglia neurons thereby removing the descending excitatory drive to specific thoracic neurons.

The first reported case of facial paralysis due to an inflammatory pseudotumor (IPT) of the facial nerve as a complication of epidermal nevus syndrome (ENS) is herein presented. A 10-month-old female patient was diagnosed with ENS at 3 months of age. She was referred to us because of moderate left facial paralysis. Epidermal nevi of her left auricle extended deep into the external ear canal. Otoscopy revealed polypous nevi and cholesteatoma debris filling the left ear. Computed tomography showed a soft mass filling the ear canal, including the middle ear, and an enormously enlarged facial nerve. Surgical exploration revealed numerous polypous nevi, external ear cholesteatoma, and tumorous swelling of the facial nerve. The middle ear ossicles were completely lost. The facial paralysis was improved after decompression surgery, but recurred 5 months later. A second operation was conducted 10 months after the first. During this operation, facial nerve decompression was completed from the geniculate ganglion to near the stylomastoid foramen. Histological diagnosis of the facial nerve tumor was IPT probably caused by chronic external ear inflammation induced by epidermal nevi. The facial paralysis gradually improved to House-Blackmann grade III 5 years after the second operation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

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.

Facial paralysis often has a significant emotional impact on patients. Along with the myriad of new surgical techniques in managing facial paralysis comes the challenge of selecting the most effective procedure for the patient. This review delineates common surgical techniques and reviews state-of-the-art techniques. The options for dynamic reanimation of the paralyzed face must be examined in the context of several patient factors, including age, overall health, and patient desires. The best functional results are obtained with direct facial nerve anastomosis and interpositional nerve grafts. In long-standing facial paralysis, temporalis muscle transfer gives a dependable and quick result. Microvascular free tissue transfer is a reliable technique with reanimation potential whose results continue to improve as microsurgical expertise increases. Postoperative results can be improved with ancillary soft tissue procedures, as well as botulinum toxin. The paper provides an overview of recent advances in facial reanimation, including preoperative assessment, surgical reconstruction options, and postoperative management.

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.

Irregular vocal fold dynamics incited by asymmetric fluid loading in a model of recurrent laryngeal nerve paralysis

Sommer, David; Erath, Byron D.; Zanartu, Matias; Peterson, Sean D.

Voiced speech is produced by dynamic fluid-structure interactions in the larynx. Traditionally, reduced order models of speech have relied upon simplified inviscid flow solvers to prescribe the fluid loadings that drive vocal fold motion, neglecting viscous flow effects that occur naturally in voiced speech. Viscous phenomena, such as skewing of the intraglottal jet, have the most pronounced effect on voiced speech in cases of vocal fold paralysis where one vocal fold loses some, or all, muscular control. The impact of asymmetric intraglottal flow in pathological speech is captured in a reduced order two-mass model of speech by coupling a boundary-layer estimation of the asymmetric pressures with asymmetric tissue parameters that are representative of recurrent laryngeal nerve paralysis. Nonlinear analysis identifies the emergence of irregular and chaotic vocal fold dynamics at values representative of pathological speech conditions.

The Japanese beetle (JB), Popillia japonica, exhibits rapid paralysis after consuming flower petals of zonal geranium, Pelargonium x hortorum. Activity-guided fractionations were conducted with polar flower petal extracts from P. x hortorum cv. Nittany Lion Red, which led to the isolation of a paralysis-inducing compound. High-resolution-MS and NMR ((1)H, (13)C, COSY, heteronuclear sequential quantum correlation, heteronuclear multiple bond correlation) analysis identified the paralytic compound as quisqualic acid (C(5)H(7)N(3)O(5)), a known but rare agonist of excitatory amino acid receptors. Optical rotation measurements and chiral HPLC analysis determined an L-configuration. Geranium-derived and synthetic L-quisqualic acid demonstrated the same positive paralytic dose-response. Isolation of a neurotoxic, excitatory amino acid from zonal geranium establishes the phytochemical basis for induced paralysis of the JB, which had remained uncharacterized since the phenomenon was first described in 1920.

Necrotizing sialometaplasia of the parotid gland associated with facial nerve paralysis.

2017-02-01

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.

Tubocurarine and pancuronium: a pharmacokinetic view.

Shanks, C A; Somogyi, A A; Ramzan, M I; Triggs, E J

1980-02-01

This review is an attempt to bring together the pharmacokinetic data on d-tubocurarine and pancuronium with clinical observations on relaxant dosage and effect. The modelling techniques used here represent an oversimplification of the relationships between relaxant plasma concentration and response as they do not predict either the time of onset of paralysis or its peak intensity. However, they do enable calculation of a bolus dose of relaxant required to achieve a particular intensity of paralysis for the average patient once pseudo-distribution equilibrium has been achieved. This has been further extended to predict the cumulation of the relaxants with subsequent dosage in average patients. Suggested regimens incorporating bolus and infusion doses of the relaxants to achieve continuous neuromuscular blockade have been calculated also. Averaged pharmacokinetic parameters derived from patients with renal or hepatic dysfunction have been used to predict the likely duration and intensities of paralysis for the relaxants.

Although acute flaccid paralysis is a manifestation observed in several neurologic and muscular disorders, vaccine-associated paralytic poliomyelitis (VAPP) is an exceedingly rare etiology. In the clinical setting of acute flaccid paralysis, MRI is useful in differentiating between VAPP and other conditions. Additionally, MRI can assess the extent of lesions. However, reports on MRI findings in VAPP are scarce in the pediatric radiology literature. We report a Brazilian infant who developed VAPP 40 days after receiving the first dose of oral polio vaccine (OPV). MR images of the cervical and thoracic spinal cord showed lesions involving the anterior horn cell, with increased signal intensity on T2-weighted sequences. We would like to emphasize the importance of considering VAPP as a differential diagnosis in patients with acute flaccid paralysis and an MRI showing involvement of medulla oblongata or spinal cord, particularly in countries where OPV is extensively administered.

A comprehensive approach to long-standing facial paralysis based on lengthening temporalis myoplasty.

Labbè, D; Bussu, F; Iodice, A

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. For a comprehensive treatment of the paralysis, the eyelids are usually managed by Paul Tessier's technique to lengthen the levator muscle of the upper eyelid by aponeurosis interposition, combined with external blepharorrhaphy with Krastinova-Lolov's technique. Facial reanimation using lengthening temporalis myoplasty is a dynamic procedure that has its roots in the techniques of Gillies and McLaughlin. This method is a true lengthening myoplasty procedure using no intermediate grafts. In general, the results with a 1-stage combination of lengthening temporalis myoplasty and static correction of the lagophthalmos appear comparable with the major series in the literature using free microneurovascular transfers combined with cross-facial nerve grafts for longstanding peripheral monolateral facial paralysis. The obvious advantages of temporalis elongation myoplasty consist in its technical ease, a single step, low incidence of complications and markedly reduced operating time.

The interaction between patient- and observer-perceived quality of life (QOL) and facial paralysis-related disability and the resulting effect of these interactions on social perception are incompletely understood. To measure the associations between observer-perceived disability and QOL and patient-perceived disability and QOL in patients with facial paralysis. This prospective study in an academic tertiary referral center included 84 naive observers who viewed static and dynamic images of faces with unilateral, House-Brackmann grades IV to VI facial paralysis (n = 16) and demographically matched images of nonparalyzed control individuals (n = 4). Data were collected from June 1 to August 1, 2014, and analyzed from August 2 to December 1, 2014. Observers rated the patient and control images in 6 clinically relevant domains. The patients self-reported their disability and QOL using validated tools, such as the Facial Clinimetric Evaluation Scale. Quality of life, severity of paralysis, and disability were measured on a 100-point visual analog scale. The 84 observers (59 women [70%] and 25 men [30%]) ranged in age from 20 to 68 years (mean [SD] age, 35.2 [11.9]). Structural equation modeling showed that for each 1-point decrease in a patient's Facial Clinimetric Evaluation Scale score, the patient's visual analog scale QOL improved by 0.36 (SE, 0.03; 95% CI, 0.31-0.42) points. Similarly, from an observer perspective, as the perceived disability (-0.29 [SE, 0.04; 95% CI, -0.36 to -0.22]) and severity (-0.21 [SE, 0.03; 95% CI, -0.28 to -0.14]) decreased, the perceived QOL improved. Furthermore, attractive faces were viewed as having better QOL (disability, severity, and attractiveness regression coefficients, -0.29 [SE, 0.04; 95% CI, -0.36 to -0.22], -0.21 [SE, 0.03; 95% CI, -0.28 to -0.14], and 0.32 [SE, 0.03; 95% CI, 0.26 to 0.39], respectively). An inverse association was found between a paralyzed patient's self-reported QOL rating and the observers' perceived QOL. This association was complex and was mediated through perceived severity and disability. Observers judged the severity of paralyzed faces to be 3.61 (SE, 1.80; 95% CI, 0.09-7.14) points more severe when viewing dynamic rather than static images. Observers were more likely to rate QOL lower owing to disability than were the patients with paralysis. This finding may be explained by previous literature reporting that disabled people adjust their values to accommodate their disability, thereby limiting the negative effect on their QOL. Given the importance of QOL on social interaction, the dissonance between observers and patients in this area has important implications for the socialization of patients with facial paralysis. NA.

Objective: To investigate the optimal time of tracheotomy/arytenoidectomy and the improvement of dyspnoea, dysphonia and dysphagia after arytenoidectomy with CO₂ laser in iatrogenic bilateral vocal folds paralysis patients. Method: Thirty patients [29 females, 56 (49-60) years, one male, 49 years] with bilateral vocal cords paralysis resulted from neck surgery were retrospectively analyzed by case archived information and following-up questionnaire. The data included patients' dysponea time, degree and duration from tracheotomy/arytenoidectomy to neck surgery. Twenty sixty patients required unilateral partial/total arytenoidectomy. The results of treatment were evaluated by questionnaire including dyspnoea, dysphonia and dysphagia. Result: All patients whose bilateral vocal paralysis were resulted from thyroid gland surgery. Dysponea occurred immediately after thyroidectomy surgery in 14 cases (46.7%), and 2 years later after thyroidectomy in 13 cases (43.3%), 8 years later in 3 cases (10.0%). There was one (3.3%) patient without tracheotomy. The duration of tracheotomy/arytenoidectomy to neck surgery was significantly correlated with duration of tracheotomy/arytenoidectomy to dyspnoea appearance ( r =0.879, P <0.05), not correlated with duration of thyroid surgery to dyspnoea appearance. There is significantly negative correlation between degree of dyspnoea and duration of tracheotomy/arytenoidectomy to neck surgery ( r =0.452, P <0.05). Twenty six patients appeared dyspnoea and underwent CO₂ laser arytenoidectomy after thyoidectomy 0.5-23 years. Five patients did unilateral total arytenoidectomy and 21 patients did unilateral partial arytenoidectomy. After 12-96 months following up, dyspnoea improved in 24 patients, no improved in 2 patients. Dysphonia improved and remained in 17 patients, being worse mildly in 8 patients and obviously in one patient. Dysphagia improved and remained in 24 patients, being worse in 2 patients. There was no difference between total and partial arytenoidectomy in dyspnoea, dysphonia and dysphagia. Conclusion: The morbidity of dyspnoea was correlated with time after neck surgery. It was rarely necessary to take tracheotomy immediately in bilateral vocal fords paralysis patients after neck surgery. The severer degree of dyspnoea led to shorter duration between neck surgery and tracheotomy/arytenoidectomy. There was obvious improvement after arytenoidectomy in dyspnoea, no significant change in dysphonia and dysphagia. The effect of total arytenoidectomy on bilateral vocal paralysis was similar to partial arytenoidectomy.

The incidence of residual paralysis, i.e., a mechanomyographic train-of-four (TOF) ratio (T4/T1) less than 0.9, remains frequent. Routine acceleromyography has been proposed to detect residual paralysis in clinical practice. Although acceleromyographic data are easy to obtain, they differ from mechanomyographic data, with which they are not interchangeable. The current study aimed to determine (1) the acceleromyographic TOF ratio that detects residual paralysis with a 95% probability, and (2) the impact of calibration and normalization on this predictive acceleromyographic value. In 60 patients, recovery from neuromuscular block was assessed simultaneously with mechanomyography and acceleromyography. To obtain calibrated acceleromyographic TOF ratios in group A, the implemented calibration modus 2 was activated in the TOF-Watch S; to obtain uncalibrated acceleromyographic TOF ratios in group B, the current was manually set at 50 mA (n = 30 for each). In addition, data in group B were normalized (i.e., dividing the final TOF ratio by the baseline value). The agreement between mechanomyography and acceleromyography was assessed by calculating the intraclass correlation coefficient. Negative predictive values were calculated for detecting residual paralysis from acceleromyographic TOFs of 0.9, 0.95, and 1.0. : For a mechanomyographic TOF of 0.9 or greater, the corresponding acceleromyographic TOF was 0.95 (range, 0.86-1.0), and the negative predictive values for acceleromyographic TOFs of 0.9, 0.95, and 1.0 were 37% (95% CI, 20-56%), 70% (95% CI, 51-85%), and 97% (95% CI, 83-100%), respectively. Group B: Without normalization, an acceleromyographic TOF of 0.97 (range, 0.68-1.18) corresponded to a mechanomyographic TOF of 0.9 or greater, with negative predictive values for acceleromyographic TOFs of 0.9, 0.95, and 1.0 being 40% (95% CI, 23-59%), 60% (95% CI, 41-77%), and 77% (95% CI, 58-90%), respectively. After normalization, an acceleromyographic TOF of 0.89 (range, 0.63-1.06) corresponded to a mechanomyographic TOF of 0.9 or greater, and the negative predictive values of acceleromyographic TOFs of 0.9, 0.95, and 1.0 were 89% (95% CI, 70-98%), 92% (95% CI, 75-99%), and 96% (95% CI, 80-100%), respectively. To exclude residual paralysis reliably when using acceleromyography, TOF recovery to 1.0 is mandatory.

Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mono-neuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. Bell's palsy is a rapid unilateral facial nerve paresis (weakness) or paralysis (complete loss of movement) of unknown cause. The condition leads to the partial or complete inability to voluntarily move facial muscles on the affected side of the face. Although typically self-limited, the facial paresis/paralysis that occurs in Bell's palsy may cause significant temporary oral incompetence and an inability to close the eyelid, leading to potential eye injury. Additional long-term poor outcomes do occur and can be devastating to the patient. Treatments are generally designed to improve facial function and facilitate recovery. There are myriad treatment options for Bell's palsy, and some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, numerous diagnostic tests available are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. The primary purpose of this guideline is to improve the accuracy of diagnosis for Bell's palsy, to improve the quality of care and outcomes for patients with Bell's palsy, and to decrease harmful variations in the evaluation and management of Bell's palsy. This guideline addresses these needs by encouraging accurate and efficient diagnosis and treatment and, when applicable, facilitating patient follow-up to address the management of long-term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. The guideline is intended for all clinicians in any setting who are likely to diagnose and manage patients with Bell's palsy. The target population is inclusive of both adults and children presenting with Bell's palsy. ACTION STATEMENTS: The development group made a strong recommendation that (a) clinicians should assess the patient using history and physical examination to exclude identifiable causes of facial paresis or paralysis in patients presenting with acute-onset unilateral facial paresis or paralysis, (b) clinicians should prescribe oral steroids within 72 hours of symptom onset for Bell's palsy patients 16 years and older, (c) clinicians should not prescribe oral antiviral therapy alone for patients with new-onset Bell's palsy, and (d) clinicians should implement eye protection for Bell's palsy patients with impaired eye closure. The panel made recommendations that (a) clinicians should not obtain routine laboratory testing in patients with new-onset Bell's palsy, (b) clinicians should not routinely perform diagnostic imaging for patients with new-onset Bell's palsy, (c) clinicians should not perform electrodiagnostic testing in Bell's palsy patients with incomplete facial paralysis, and (d) clinicians should reassess or refer to a facial nerve specialist those Bell's palsy patients with (1) new or worsening neurologic findings at any point, (2) ocular symptoms developing at any point, or (3) incomplete facial recovery 3 months after initial symptom onset. The development group provided the following options: (a) clinicians may offer oral antiviral therapy in addition to oral steroids within 72 hours of symptom onset for patients with Bell's palsy, and (b) clinicians may offer electrodiagnostic testing to Bell's palsy patients with complete facial paralysis. The development group offered the following no recommendations: (a) no recommendation can be made regarding surgical decompression for patients with Bell's palsy, (b) no recommendation can be made regarding the effect of acupuncture in patients with Bell's palsy, and (c) no recommendation can be made regarding the effect of physical therapy in patients with Bell's palsy.

Evidence from the use of vibration during procaine nerve block that the spindle group II fibres contribute excitation to the tonic stretch reflex of the decerebrate cat

1. Experiments have been performed to test the hypothesis that the group II fibres from the secondary endings of the muscle spindle provide an excitatory contribution to the tonic stretch reflex of the decerebrate cat. They have consisted of studying the effect of fusimotor paralysis by procaine, applied to the muscle nerve, on the reflex response to the combined stimuli of stretch (5-9 mm at 5 mm/sec) and of high-frequency vibration (100-150 Hz, 150 μm). 2. The reflex response to the combined stimuli was found to be paralysed in two distinct stages which paralleled those of the ordinary stretch reflex described earlier. The two phases of paralysis may be attributed to an early paralysis of the γ efferents followed by a later paralysis of the Ia afferents and α motor fibres. However, the Ia discharges elicited by the combined stimuli, unlike those elicited by simple stretch, should have remained unchanged on γ efferent paralysis since the Ia firing frequency may be presumed to have been clamped at the vibration frequency by the occurrence of one-to-one `driving'. The early reduction of the response to the combined stimuli may thus be attributed to the removal of a stretchevoked autogenetic excitatory input other than that long known to be provided by the Ia pathway. This supports the view that the spindle group II fibres have such an action, since their firing will be appropriately reduced on γ efferent paralysis by removal of their pre-existing fusimotor bias; there is no evidence for the existence of any other group of fibres with the right properties. 3. Recording of compound action potentials and of single units confirmed the great sensitivity of the γ efferents to procaine but showed that the group II fibres were nearly as resistant as the Ia fibres and α motor fibres. 4. The reliability of one-to-one driving of the Ia discharges by the vibration was tested in control experiments in which the reflex was elicited by an asymmetrical vibratory waveform with a rapid rising phase (1·5 or 1·9 msec at 140 Hz) and a slower falling phase. Recordings from single units showed that the use of this wave form greatly diminished any tendency to double driving (2 spikes/cycle of vibration) during the dynamic phase of stretch and never elicited it during the static phase of stretch when the reflex measurements were made. These `pulsed' vibrations elicited reflex contractions which were of the same general size and which were paralysed in the same two phases by procaine as those elicited by sinusoidal vibrations. This eliminates the possibility that the early phase of paralysis might have been due to conversion of the pattern of Ia firing from double to single driving on γ efferent paralysis. 5. Wedensky inhibition of the afferent fibres could not be held responsible for the early phase of paralysis. 6. The results are taken to strengthen the hypothesis that the spindle group II fibres contribute excitation rather than inhibition to the stretch reflex. The particular support derived from the present experiments is that all measurements of the size of the reflex at various times were made with the muscle at the same length so that the findings cannot be attributed to the tension-length properties of muscle. The detailed mechanism of the excitation, however, remains to be established and certain of the present findings suggest that it may not be a direct one. PMID:4271734

Bell palsy is the most common neurologic condition affecting the cranial nerves. Lagophthalmos, exposure keratopathy, and corneal ulceration are potential complications. In this review, we evaluate various causes of facial paralysis as well as the level 1 evidence supporting the use of a short course of oral steroids for idiopathic Bell palsy to improve functional outcomes. Various surgical and nonsurgical techniques are also discussed for the management of residual facial dysfunction. Copyright © 2018. Published by Elsevier Inc.

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.

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.

The developing shoulder has a limited capacity to recover after a short duration of neonatal paralysis

Mechanical stimuli are required for the proper development of the musculoskeletal system. Removal of muscle forces during fetal or early post-natal timepoints impairs the formation of bone, tendon, and their attachment (the enthesis). The goal of the current study was to examine the capacity of the shoulder to recover after a short duration of neonatal rotator cuff paralysis, a condition mimicking the clinical condition neonatal brachial plexus palsy. We asked if reapplication of muscle load to a transiently paralyzed muscle would allow for full recovery of tissue properties. CD-1 mice were injected with botulinum toxin A to paralyze the supraspinatus muscle from birth through 2 weeks and subsequently allowed to recover. The biomechanics of the enthesis was determined using tensile testing and the morphology of the shoulder joint was determined using micro computed tomography and histology. A recovery period of at least 10 weeks was required to achieve control properties, demonstrating a limited capacity of the shoulder to recover after only two weeks of muscle paralysis. Although care must be taken when extrapolating results from an animal model to the human condition, the results of the current study imply that treatment of neonatal brachial plexus palsy should be aggressive, as even short periods of paralysis could lead to long-term deficiencies in enthesis biomechanics and shoulder morphology.

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.

(1) To evaluate the efficacy of modified arytenoid adduction in the management of patients with symptomatic cancer-related unilateral vocal fold paralysis, and (2) to assess the impact of this treatment on patients' quality of life. Forty-two patients with cancer-related unilateral vocal fold paralysis underwent modified arytenoid adduction between February 2001 and December 2008. Of these, 37 patients were enrolled in this retrospective study (one patient died of primary disease and four were lost to follow up). Laryngostroboscopy was performed to evaluate vocal fold orientation and mobility. Pre- and post-operative assessment of subjective and objective voice, aerodynamic parameters, and quality of life were also undertaken, and aspiration was subjectively rated. Laryngostroboscopic findings indicated a significant post-operative improvement in vocal fold posterior glottal closure and vertical gap. Significant improvements in voice quality, aerodynamic parameters and quality of life were noted three months post-operatively in all patients (p < 0.01). The overall success rate for swallowing rehabilitation was 94.6 per cent (35/37). Subjective aspiration ratings decreased significantly post-operatively, compared with pre-operative values (p < 0.01). No major complication occurred in any patient, except for dyspnoea in one patient. Modified arytenoid adduction is an effective and reliable medialisation technique which can restore satisfactory voice quality, prevent aspiration and lead to a better quality of life for patients with cancer-related unilateral vocal fold paralysis.

Mutations in the skeletal muscle channel (SCN4A), encoding the Nav1.4 voltage-gated sodium channel, are causative of a variety of muscle channelopathies, including non-dystrophic myotonias and periodic paralysis. The effects of many of these mutations on channel function have been characterized both in vitro and in vivo. However, little is known about the consequences of SCN4A mutations downstream from their impact on the electrophysiology of the Nav1.4 channel. Here we report the discovery of a novel SCN4A mutation (c.1762A>G; p.I588V) in a patient with myotonia and periodic paralysis, located within the S1 segment of the second domain of the Nav1.4 channel. Using N-ethyl-N-nitrosourea mutagenesis, we generated and characterized a mouse model (named draggen), carrying the equivalent point mutation (c.1744A>G; p.I582V) to that found in the patient with periodic paralysis and myotonia. Draggen mice have myotonia and suffer from intermittent hind-limb immobility attacks. In-depth characterization of draggen mice uncovered novel systemic metabolic abnormalities in Scn4a mouse models and provided novel insights into disease mechanisms. We discovered metabolic alterations leading to lean mice, as well as abnormal AMP-activated protein kinase activation, which were associated with the immobility attacks and may provide a novel potential therapeutic target.

Surgical management of facial nerve paralysis in the pediatric population.

PubMed

Barr, Jason S; Katz, Karin A; Hazen, Alexes

2011-11-01

In the pediatric patient population, both the pathology and the surgical managements of seventh cranial nerve palsy are complicated by the small size of the patients. Adding to the technical difficulty is the relative infrequency of the diagnosis, thus making it harder to become proficient in the management of the condition. The magnitude of the functional and aesthetic deficits these children manifest is significantly troubling to both the patient and the parents, which makes immediate attention, treatment, and functional restoration essential. A literature search using PubMed (http://www.pubmed.org) was undertaken to identify the current state of surgical management of pediatric facial paralysis. Although a multitude of techniques have been used, the ideal reconstructive procedure that addresses all of the functional and cosmetic needs of these children has yet to be described. Certainly, future research and innovative thinking will yield progressively better techniques that may, one day, emulate the native facial musculature with remarkable precision. The necessity for surgical intervention in children with facial nerve paralysis differs depending on many factors including the acute/chronic nature of the defect as well as the extent of functional and cosmetic damage. In this article, we review the surgical procedures that have been used to treat pediatric facial nerve paralysis and provide therapeutic facial reanimation. Copyright © 2011 Elsevier Inc.

Cross-face nerve grafting for reanimation of incomplete facial paralysis: quantitative outcomes using the FACIAL CLIMA system and patient satisfaction.

PubMed

Hontanilla, Bernardo; Marre, Diego; Cabello, Alvaro

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.

The purpose of this study was to develop an evidence-based consensus statement regarding use of laryngeal electromyography (LEMG) for diagnosis and treatment of vocal fold paralysis after recurrent laryngeal neuropathy (RLN). Two questions regarding LEMG were analyzed: (1) Does LEMG predict recovery in patients with acute unilateral or bilateral vocal fold paralysis? (2) Do LEMG findings change clinical management in these individuals? A systematic review was performed using American Academy of Neurology criteria for rating of diagnostic accuracy. Active voluntary motor unit potential recruitment and presence of polyphasic motor unit potentials within the first 6 months after lesion onset predicted recovery. Positive sharp waves and/or fibrillation potentials did not predict outcome. The presence of electrical synkinesis may decrease the likelihood of recovery, based on 1 published study. LEMG altered clinical management by changing the initial diagnosis from RLN in 48% of cases. Cricoarytenoid fixation and superior laryngeal neuropathy were the most common other diagnoses observed. If prognostic information is required in a patient with vocal fold paralysis that is more than 4 weeks and less than 6 months in duration, then LEMG should be performed. LEMG may be performed to clarify treatment decisions for vocal fold immobility that is presumed to be caused by RLN. Muscle Nerve 53: 850-855, 2016. © 2016 Wiley Periodicals, Inc.

Exclusion of linkage between hypokalemic periodic paralysis and a candidate region in 1q31-32 suggests genetic heterogeneity

Familial hypokalemic periodic paralysis (HOKPP) is an autosomal dominant disease with attacks of paralysis of varying severity. The attacks occur at intervals of days to years in otherwise healthy people combined with hypokalemia during attacks. The paralysis attacks are precipitated by a number of different factors, like carbohydrate-rich meals, cold, exercise and mental stress. Recently linkage for HOKPP was shown for chromosome 1q31-32 and the disease was mapped between D1S413 and D1S249. The gene for the calcium channel alfa1-subunit (CACNL 1A3) maps to this interval and in two families no recombination was found between a polymorphism in the CACNL 1A3more » gene and the disease. This gene is therefore considered to be a candidate for HOKPP. The analysis of a large Danish family excludes linkage to this region and to the CACNL 1A3 gene. In each direction from D1S413, 18.8 cM could be excluded and for D1S249, 14.9 cM. The present study clearly excludes the possibility that the gene causing HOKPP in a large Danish family is located in the region 1q31-32. This result shows that HOKPP is a heterogenous disease, with only one mapped gene so far.« less

Asymmetric Weakness and West Nile Virus Infection.

Kuo, Dick C; Bilal, Saadiyah; Koller, Paul

2015-09-01

Weakness is a common presentation in the emergency department (ED). Asymmetric weakness or weakness that appears not to follow an anatomical pattern is a less common occurrence. Acute flaccid paralysis with no signs of meningoencephalitis is one of the more uncommon presentations of West Nile virus (WNV). Patient may complain of an acute onset of severe weakness, or even paralysis, in one or multiple limbs with no sensory deficits. This weakness is caused by injury to the anterior horn cells of the spinal cord. We present a case of acute asymmetric flaccid paralysis with preserved sensory responses that was eventually diagnosed as neuroinvasive WNV infection. A 31-year-old male with no medical history presented with complaints of left lower and right upper extremity weakness. Computed tomography scan was negative and multiple other studies were performed in the ED. Eventually, he was admitted to the hospital and was found to have decreased motor amplitudes, severely reduced motor neuron recruitment, and denervation on electrodiagnostic study. Cerebrospinal fluid specimen tested positive for WNV immunoglobulin (Ig) G and IgM antibodies. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute asymmetric flaccid paralysis with no signs of viremia or meningoencephalitis is an unusual presentation of WNV infection. WNV should be included in the differential for patients with asymmetric weakness, especially in the summer months in areas with large mosquito populations. Copyright © 2015 Elsevier Inc.

Although vocal cord paralysis (VCP) following thyroidectomy is primarily associated with surgical trauma, it is not the sole etiology. Vocal cord paralysis following thyroidectomy can be caused by a vocal cord hematoma with an incidence of 1.4% due to direct injury during orotracheal intubation. In this article, we present a case of VCP caused by vocal cord hematoma. A 32-year-old male patient who has been receiving propylthiouracil treatment for toxic multinodular goiter since 10 years was admitted to our hospital to be operated because of persisting complaints. The patient was hospitalized for sutureless thyroidectomy after he became euthyroid. Preoperative fiberoptic laryngoscopy performed by the ear, nose, and throat department revealed bilaterally motile vocal folds and a completely open airway. Patient underwent sutureless total thyroidectomy with a vessel sealing device (Ligasure TM LF1212, Covidien, CO), and a minivac drainage system was placed in the thyroid lodge. On the morning of the first postoperative day, 50 mL of serosanguinous fluid was drained. The patient's voice was normal, and there was no ecchymosis. Postoperative fiberoptic laryngoscopy revealed a hematoma near the right vocal fold and paralysis of the right vocal fold; however, the airway was open. It should be kept in mind that VCP is not solely due to surgery but can also result from intubation, as observed in this case.

This study aims to evaluate the demographic and clinical characteristics of patients with idiopathic and non-idiopathic vocal cord paralysis (VCP). This retrospective cohort was performed on data extracted from medical files of 92 consecutive patients (43 males, 49 females; median age 52.1±23.1 years; min. 1 - max. 87) with VCP diagnosed in the otorhinolaryngology department between April 2012 and December 2015. Diagnoses associated with VCP, side of involvement (right, left or bilateral) and previous medical histories were noted and compared between patients with idiopathic and non-idiopathic VCP. Vocal cord paralysis occurred on the left side (n=56, 60.9%), right side (n=28, 30.4%) or bilaterally (n=8, 8.7%). A clinical entity related with VCP was identified in 63 patients (68.5%), while 29 (31.5%) patients had idiopathic VCP. Most common etiologies for VCP were thyroid surgery (n=32, 34.8%), cardiovascular surgery (n=9, 9.8%), lung cancer (n=6, 6.5%) and cardiac anomalies (n=4, 4.3%), respectively. Patients with idiopathic VCP were significantly older (p<0.001), while gender distribution (p=0.121) and side of involvement (p=0.340) did not differ between two groups. Vocal cord paralysis is a relatively common clinical entity with substantial rate of morbidity. Identification of the underlying etiology and awareness on the clinical characteristics are keystones for foreseeing complications and determining the appropriate therapeutic modality.

The Chronic bee paralysis virus (CBPV) is the aetiological agent of chronic bee paralysis, a contagious disease associated with nervous disorders in adult honeybees leading to massive mortalities in front of the hives. Some of the clinical signs frequently reported, such as trembling, may be confused with intoxication syndromes. Therefore, laboratory diagnosis using real-time PCR to quantify CBPV loads is used to confirm disease. Clinical signs of chronic paralysis are usually associated with viral loads higher than 10 8 copies of CBPV genome copies per bee (8 log 10 CBPV/bee). This threshold is used by the European Union Reference Laboratory for Bee Health to diagnose the disease. In 2015, the accuracy of measurements of three CBPV loads (5, 8 and 9 log 10 CBPV/bee) was assessed through an inter-laboratory study. Twenty-one participants, including 16 European National Reference Laboratories, received 13 homogenates of CBPV-infected bees adjusted to the three loads. Participants were requested to use the method usually employed for routine diagnosis. The quantitative results (n=270) were analysed according to international standards NF ISO 13528 (2015) and NF ISO 5725-2 (1994). The standard deviations of measurement reproducibility (S R ) were 0.83, 1.06 and 1.16 at viral loads 5, 8 and 9 log 10 CBPV/bee, respectively. The inter-laboratory confidence of viral quantification (+/- 1.96S R ) at the diagnostic threshold (8 log 10 CBPV/bee) was+/- 2.08 log 10 CBPV/bee. These results highlight the need to take into account the confidence of measurements in epidemiological studies using results from different laboratories. Considering this confidence, viral loads over 6 log 10 CBPV/bee may be considered to indicate probable cases of chronic paralysis. Copyright © 2017 The Authors. Published by Elsevier B.V.

Although herpes simplex virus type 1 (HSV-1) is a causative agent of Bell palsy, the precise mechanism of the paralysis remains unknown. It is necessary to investigate the pathogenesis and treatment of Bell palsy due to HSV-1 infection. This study elucidated the role of nitric oxide (NO) in the incidence of facial nerve paralysis caused by HSV-1 in mice and to evaluate the possible role of edaravone, a free radical scavenger, in preventing the paralysis. Sixty-two mice served as animal models of Bell palsy in this laboratory study conducted at an academic institution. Levels of NO in the facial nerve were measured using high-performance liquid chromatography and absorption photometry. The incidence of facial palsy was assessed following administration of edaravone immediately after HSV-1 inoculation and daily for 11 days thereafter. The ratio of NO (inoculated side to control side) and incidence of facial palsy. RESULTS Before the onset of facial palsy, no substantial difference in the NO level was noted between the HSV-1-inoculated side and the control side. When facial palsy occurred, usually at 7 days after inoculation, the NO level was significantly higher on the inoculated side than on the control side. Following recovery from the palsy, the high NO level of the inoculated side decreased. No increase in the NO level was observed in animals without transient facial palsy. When edaravone was administered, the incidence of facial palsy decreased significantly. These findings suggest that NO produced by inducible NO synthase in the facial nerve plays an important role in the onset of facial palsy caused by HSV-1 infection, which is considered a causative virus of Bell palsy. Hato and colleagues elucidate the role of nitric oxide in HSV-1–related facial nerve paralysis in mice and evaluate the role of edaravone, a free radical scavenger, in preventing the paralysis.

Refinement of myotome values in the upper limb: Evidence from brachial plexus injuries.

Bell, S W; Brown, M J C; Hems, T J

2017-02-01

We reviewed patients with partial supraclavicular brachial plexus injuries in order to refine the myotome values of the upper limb. Forty-two patients with defined partial injuries to the supraclavicular brachial plexus were reviewed from a prospective database. The injuries patterns covered C5, C5-6, C5-7, C5-8, C7-T1 and C8-T1 roots. Upper plexus injuries were classified on the basis of surgical exploration and intraoperative stimulation and lower plexus injuries from MRI. Flexor Carpi Radialis (FCR) was paralyzed in C5-7 injuries, in addition to paralysis of deltoid, supraspinatus, infraspinatus and biceps, when compared to C5-6 injuries. Complete paralysis of Flexor Digitorum Profundus (FDP) and Flexor Digitorum Superficialis (FDS) to all digits was identified in C7-T1 injuries. In C5-8 injuries weakness was noted in FDP of ulnar digits and intrinsics innervated by the ulnar nerve, while in C8-T1 injuries paralysis was noted in the FDP to the radial digits. All patients with C8-T1 injuries had paralysis of FDS and the thenar muscles. In upper plexus injuries paralysis of FCR indicated involvement of C7 root in addition to C5 and C6 roots. The results provide new detail of innervation of muscles acting on the hand. Flexor muscles and intrinsic muscles of the thumb and radial fingers (median nerve) have an important contribution from T1, while for those acting on the ulnar digits (ulnar nerve) the main contribution is from C8 with some input from C7. T1 also gives consistent innervation to extensor pollicis longus. A revised myotome chart for the upper limb is proposed.

1999-10-01

In 1997, two patients were admitted to Tikur Anbessa Hospital with complaints of ascending paralysis in all extremities following administration of sheep brain tissue anti-rabies vaccine following a rabies exposure. The paralysis had started after 14 daily subcutaneous injections of the Fermi type nerve tissue vaccine. After an eight week stay in the hospital with supportive care and physiotherapy, the patients showed remarkable improvement. They received a booster dose of vaccine while in the hospital, with no deterioration in their neurological status and were discharged.

[Treatment of idiopathic peripheral facial nerve paralysis (Bell's palsy)].

PubMed

Meyer, Martin Willy; Hahn, Christoffer Holst

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.

Hypokalemic periodic paralysis; two different genes responsible for similar clinical manifestations

PubMed Central

Kim, Hunmin; Hwang, Hee; Cheong, Hae Il

2011-01-01

Primary hypokalemic periodic paralysis (HOKPP) is an autosomal dominant disorder manifesting as recurrent periodic flaccid paralysis and concomitant hypokalemia. HOKPP is divided into type 1 and type 2 based on the causative gene. Although 2 different ion channels have been identified as the molecular genetic cause of HOKPP, the clinical manifestations between the 2 groups are similar. We report the cases of 2 patients with HOKPP who both presented with typical clinical manifestations, but with mutations in 2 different genes (CACNA1Sp.Arg528His and SCN4A p.Arg672His). Despite the similar clinical manifestations, there were differences in the response to acetazolamide treatment between certain genotypes of SCN4A mutations and CACNA1S mutations. We identified p.Arg672His in the SCN4A gene of patient 2 immediately after the first attack through a molecular genetic testing strategy. Molecular genetic diagnosis is important for genetic counseling and selecting preventive treatment. PMID:22253645

Practical aspects in the management of hypokalemic periodic paralysis

PubMed Central

Levitt, Jacob O

2008-01-01

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 . PMID:18426576

Progressive paralysis associated with diffuse astrocyte anaplasia in delta 202 mice homozygous for a transgene encoding the SV40 T antigen.

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.

Objective grading of facial paralysis using Local Binary Patterns in video processing.

PubMed

He, Shu; Soraghan, John J; O'Reilly, Brian F

2008-01-01

This paper presents a novel framework for objective measurement of facial paralysis in biomedial videos. The motion information in the horizontal and vertical directions and the appearance features on the apex frames are extracted based on the Local Binary Patterns (LBP) on the temporal-spatial domain in each facial region. These features are temporally and spatially enhanced by the application of block schemes. A multi-resolution extension of uniform LBP is proposed to efficiently combine the micro-patterns and large-scale patterns into a feature vector, which increases the algorithmic robustness and reduces noise effects while still retaining computational simplicity. The symmetry of facial movements is measured by the Resistor-Average Distance (RAD) between LBP features extracted from the two sides of the face. Support Vector Machine (SVM) is applied to provide quantitative evaluation of facial paralysis based on the House-Brackmann (H-B) Scale. The proposed method is validated by experiments with 197 subject videos, which demonstrates its accuracy and efficiency.

2015-01-01

The health and vigour of honeybee colonies are threatened by numerous parasites (such as Varroa destructor and Nosema spp.) and pathogens, including viruses, bacteria, protozoa. Among honeybee pathogens, viruses are one of the major threats to the health and well-being of honeybees and cause serious concern for researchers and beekeepers. To tone down the threats posed by these invasive organisms, a better understanding of bee viral infections will be of crucial importance in developing effective and environmentally benign disease control strategies. Here we summarize recent progress in the understanding of the morphology, genome organization, transmission, epidemiology and pathogenesis of eight honeybee viruses: Deformed wing virus (DWV) and Kakugo virus (KV); Sacbrood virus (SBV); Black Queen cell virus (BQCV); Acute bee paralysis virus (ABPV); Kashmir bee virus (KBV); Israeli Acute Paralysis Virus (IAPV); Chronic bee paralysis virus (CBPV). The review has been designed to provide researchers in the field with updated information about honeybee viruses and to serve as a starting point for future research. PMID:27800411

[Diaphragm pacing for the ventilatory support of the quadriplegic patients with respiratory paralysis].

1992-02-01

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.

To evaluate the clinical and radiological aspects of otic capsule sparing temporal bone fractures. Using medical records, 188 temporal bones of 173 patients with otic capsule sparing temporal bone fractures were evaluated. Otoscopic findings and symptoms, facial paralysis, and hearing loss were assessed. Using regional analysis, 7 fractures were classified as type I, 85 as type II, 169 as type III and 114 as type IV. Fourteen of the 17 facial paralysis cases improved to House-Brackmann grade II or lower at an average of 57.6 days after the initial evaluation. Thirty-one patients underwent initial and follow-up pure tone audiometry examinations. The air-bone gap closed significantly from 27.2 dB at an average of 21.8 days post-trauma to 19.6 dB at an average of 79.9 days post-trauma, without the need for surgical intervention. Initial conservative treatment for facial paralysis or conductive hearing loss is possible in otic capsule sparing fracture cases after careful evaluation of the patient.

Acute quadriplegia from hyperkalemia: a case report and literature review.

Hyperkalemia has been described as a rare and under recognized cause of acute quadriplegia. A 52-year-old man with end-stage renal disease presented with ascending quadriplegia and dyspnea for 2 days. He had life-threatening hyperkalemia (9.0 mEq/L). His electrocardiogram showed typical features of hyperkalemia. His symptoms improved in 30 minutes and completely resolved in 5 hours after emergent treatment of hyperkalemia. He admitted eating large amounts of high potassium foods and taking ibuprofen in uncertain quantities. We reviewed 62 articles and identified 73 patients with secondary hyperkalemic paralysis. Common presentations were diminished reflexes, quadriparesis/paralysis, respiratory involvement, and sensory loss. Almost half of all patients had potassium levels higher than 9 mEq/L. Complete recovery, achieved in 89% of patients, did not correlate either with the absolute potassium level or the degree to which it was corrected. Hyperkalemia is a rare but treatable cause of acute flaccid paralysis that requires immediate treatment. Late diagnosis can delay appropriate treatment leading to cardiac arrhythmias and arrest.

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.

Common questions about Bell palsy.

PubMed

Albers, Janet R; Tamang, Stephen

2014-02-01

Bell palsy is an acute affliction of the facial nerve, resulting in sudden paralysis or weakness of the muscles on one side of the face. Testing patients with unilateral facial paralysis for diabetes mellitus or Lyme disease is not routinely recommended. Patients with Lyme disease typically present with additional manifestations, such as arthritis, rash, or facial swelling. Diabetes may be a comorbidity of Bell palsy, but testing is not needed in the absence of other indications, such as hypertension. In patients with atypical symptoms, magnetic resonance imaging with contrast enhancement can be used to rule out cranial mass effect and to add prognostic value. Steroids improve resolution of symptoms in patients with Bell palsy and remain the preferred treatment. Antiviral agents have a limited role, and may improve outcomes when combined with steroids in patients with severe symptoms. When facial paralysis is prolonged, surgery may be indicated to prevent ocular desiccation secondary to incomplete eyelid closure. Facial nerve decompression is rarely indicated or performed. Physical therapy modalities, including electrostimulation, exercise, and massage, are neither beneficial nor harmful.

Facial palsy: what can the multidisciplinary team do?

Butler, Daniel P; Grobbelaar, Adriaan O

2017-01-01

The functional and psychosocial impact of facial paralysis on the patient is significant. In response, a broad spectrum of treatment options exist and are provided by a multitude of health care practitioners. The cause and duration of the facial weakness can vary widely and the optimal care pathway varies. To optimize patient outcome, those involved in the care of patients with facial palsy should collaborate within comprehensive multidisciplinary teams (MDTs). At an international level, those involved in the care of patients with facial paralysis should aim to create standardized guidelines on which outcome domains matter most to patients to aid the identification of high quality care. This review summarizes the causes and treatment options for facial paralysis and discusses the subsequent importance of multidisciplinary care in the management of patients with this condition. Further discussion is given to the extended role of the MDT in determining what constitutes quality in facial palsy care to aid the creation of accepted care pathways and delineate best practice.

[Trigeminal motor paralysis and dislocation of the temporo-mandibular joints].

PubMed

Ohkawa, S; Yoshida, T; Ohsumi, Y; Tabuchi, M

1996-07-01

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.

Franklin Delano Roosevelt's (FDR's) (1882-1945) 1921 neurological disease revisited; the most likely diagnosis remains Guillain-Barré syndrome.

In 2003, we published evidence that the most likely cause of FDR's 1921 neurological disease was Guillain-Barré syndrome. Afterwards, several historians and neurologists stated in their publications that FDR had paralytic poliomyelitis. However, significant criticism of our article or new support for that diagnosis was not revealed. One critic claimed that FDR's cerebrospinal fluid indicated poliomyelitis, but we did not find evidence that a lumbar puncture was performed. The diagnosis of FDR's neurological disease still depends upon documented clinical abnormalities. His age, prolonged symmetric ascending paralysis, transient numbness, protracted dysaesthesia (pain on slight touch), facial paralysis, bladder and bowel dysfunction, and absence of meningismus are typical of Guillain-Barré syndrome and are inconsistent with paralytic poliomyelitis. FDR's prolonged fever was atypical for both diseases. Finally, permanent paralysis, though commoner in paralytic poliomyelitis, is frequent in Guillain-Barré syndrome. Thus, the clinical findings indicate the most likely diagnosis in FDR's case remains Guillain-Barré syndrome. © IMechE 2015.

Efficacy and safety of acute injection laryngoplasty for vocal cord paralysis following thoracic surgery.

2011-11-01

The primary objective of this study was to evaluate the effectiveness and safety of injection laryngoplasty using a temporary injectable agent in the acute setting for patients with unilateral vocal cord paralysis following thoracic surgical procedures. Retrospective consecutive case series in an academic institution. Inclusion criteria included patients acutely treated with injection laryngoplasty from January 1, 2006, to March 31, 2010, for a unilateral vocal cord paralysis that occurred after a thoracic surgical procedure (N = 20). All patients were injected with Radiesse Voice Gel using microlaryngoscopy technique. The mean time to vocal cord injection from the time of thoracic surgery was 4.5 days. There was one operative-related complication of intraoperative bile reflux that caused a pneumonitis. Ninety percent of patients were recommended for strict nothing by mouth prior to injection. Of these, 94% were allowed an oral diet following injection, and 67% tolerated a regular diet. None of the patients required subsequent procedures for aspiration or dysphagia, and 25% required further intervention after discharge for persistent dysphonia. Patients with a known nerve transection had a higher rate of dysphonia requiring further surgical procedures than those who did not have a known nerve transection. Acute treatment of thoracic surgery-related unilateral vocal cord paralysis with injection laryngoplasty appears safe and effective at preventing postoperative aspiration pneumonia and improves swallowing function to allow resumption of an oral diet. A single injection is often the only required treatment. Copyright © 2011 The American Laryngological, Rhinological, and Otological Society, Inc.

2017-09-01

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.

Multivectored Superficial Muscular Aponeurotic System Suspension for Facial Paralysis.

PubMed

Leach, Garrison; Kurnik, Nicole; Joganic, Jessica; Joganic, Edward

2017-06-01

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.

Initiation of bladder voiding with epidural stimulation in paralyzed, step trained rats.

The inability to control timely bladder emptying is one of the most serious challenges among the several functional deficits that occur after a complete spinal cord injury. Having demonstrated that electrodes placed epidurally on the dorsum of the spinal cord can be used in animals and humans to recover postural and locomotor function after complete paralysis, we hypothesized that a similar approach could be used to recover bladder function after paralysis. Also knowing that posture and locomotion can be initiated immediately with a specific frequency-dependent stimulation pattern and that with repeated stimulation-training sessions these functions can improve even further, we reasoned that the same two strategies could be used to regain bladder function. Recent evidence suggests that rats with severe paralysis can be rehabilitated with a multisystem neuroprosthetic training regime that counteracts the development of neurogenic bladder dysfunction. No data regarding the acute effects of locomotion on bladder function, however, were reported. In this study we show that enabling of locomotor-related spinal neuronal circuits by epidural stimulation also influences neural networks controlling bladder function and can play a vital role in recovering bladder function after complete paralysis. We have identified specific spinal cord stimulation parameters that initiate bladder emptying within seconds of the initiation of epidural stimulation. The clinical implications of these results are substantial in that this strategy could have a major impact in improving the quality of life and longevity of patients while simultaneously dramatically reducing ongoing health maintenance after a spinal cord injury.

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.

Lengthening Temporalis Myoplasty for Single-Stage Smile Reconstruction in Children with Facial Paralysis.

PubMed

Panossian, Andre

2016-04-01

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.

Periodic paralysis: rare presenting symptom of thyrotoxicosis.

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 documented. Muscle strength recovery was gradual and it was complete 4 hours after the infusion was initiated. The next day the potassium level was within normal limits but a wide pulse pressure and tachycardia still persisted.

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 < 0.05) in the control group. When comparing the treatment and control groups among the animals inoculated with Type 1 HSV, no significant difference was found with regard to perineural fibrosis, axonal degeneration, myelin degeneration, or Schwann cell proliferation. The only statistically significant advantage of the treatment group was in edema formation (P < 0.05). As a result of the evaluation of MP efficacy in different models of facial nerve palsy, we may say that this drug was without effect on nerve healing in paralysis due to nerve section and that it only reduced nervous edema in paralysis induced by Type 1 HSV, whereas it had positive effects on healing in the type of paralysis caused by nerve compression.

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 those before treatment (both P <0.05), with better result in the observation group ( P <0.05). The cured and markedly effective rate of the observation group was 74.5% (35/47), which was better than 47.7% (21/44) of the control group ( P <0.01). Special penetration needling at an angle about 45° between the penetration needle and paralysis muscle bundle is better than conventional penetration needling for refractory facial paralysis.

When is facial paralysis Bell palsy? Current diagnosis and treatment.

PubMed

Ahmed, Anwar

2005-05-01

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.

The Relationship of Isolated Sleep Paralysis and Panic Disorder to Hypertension

1988-01-01

An hypothesis is proposed that there exists a subgroup of African-American hypertensive patients whose hypertension could have been prevented by the early detection and treatment of easily recognizable symptoms that signal the initiation of the pathophysiologic processes that lead to essential hypertension. A pilot study of 31 patients with elevated blood pressure revealed that 41.9 percent had isolated sleep paralysis, 35.5 percent had panic attacks, and 9.7 percent had panic disorder. These proposed hyperadrenergic phenomena may be related to the development of hypertension in certain individuals. PMID:3351970

Lead poisoning of industrial origin in the horse (in French)

1978-01-01

In an industrial area polluted by fumes from a lead processing plant, the following symptoms were observed in horses: anemia, leanness, wind sucking at inspiration due to laryngeal paralysis, running at the nostrils due to pharyngeal paralysis (2 horses), intense dyspnea, latent asphyxia and incoordinate locomotion. A high rate of contamination of the hay, by lead (hay 837 +/- 714 ppm/dry; pasture grass 919 +/- 455 ppm/dry) was demonstrated. In the tissues of a slaughtered filly impregnation was found to be mild for lead, excessively high for cadmium.

A massive goiter may constrict the trachea resulting in shortness of breath. Recurrent laryngeal nerve compression may cause vocal cord paralysis. We highlight a case of a 62- year-old female with a 30 year history of an anterior neck swelling gradually increasing in size. She presented with acute symptoms of upper airway obstruction and voice changes. Emergency thyroidectomy was performed by dividing the middle part of the gland using ultrasonic scissors. The recovery was uneventful and the patient regained normal vocal cord function post operatively.

A 43-year-old woman who reported diplopia and headache was found to have comitant esotropia at distance fixation and normal alignment at reading distance (divergence paralysis). Eye movement, including abduction, was normal as was the rest of the neurologic examination. Brain MRI was normal. Lumbar puncture showed an elevated opening pressure and a cerebrospinal fluid formula consistent with viral meningitis. The patient was treated with intravenous fluids and analgesics and with a temporary prism to alleviate diplopia. Within 3 weeks, she had fully recovered. This is the first report of divergence palsy in viral meningitis.

An outbreak of flaccid paralysis syndrome in adults is ongoing in Congo. Molecular analysis of faecal, throat and cerebrospinal samples identified wildtype 1 poliovirus and an additional enterovirus C strain related to enterovirus 109 as the cause. As of 22 November, the cumulative number of cases was 409, of which 169 (41.3%) were fatal. This is one of the largest wild type 1 poliovirus outbreaks ever described associated with an unusually high case fatality rate.

Psychological wellbeing, physical impairments and rural aging in a developing country setting.

There has been very little research on wellbeing, physical impairments and disability in older people in developing countries. A community survey of 1147 older parents, one per household, aged sixty and over in rural Thailand. We used the Burvill scale of physical impairment, the Thai Psychological Wellbeing Scale and the brief WHO Disability Assessment Schedule. We rated received and perceived social support separately from children and from others and rated support to children. We used weighted analyses to take account of the sampling design. Impairments due to arthritis, pain, paralysis, vision, stomach problems or breathing were all associated with lower wellbeing. After adjusting for disability, only impairment due to paralysis was independently associated with lowered wellbeing. The effect of having two or more impairments compared to none was associated with lowered wellbeing after adjusting for demographic factors and social support (adjusted difference -2.37 on the well-being scale with SD = 7.9, p < 0.001) but after adjusting for disability the coefficient fell and was non-significant. The parsimonious model for wellbeing included age, wealth, social support, disability and impairment due to paralysis (the effect of paralysis was -2.97, p = 0.001). In this Thai setting, received support from children and from others and perceived good support from and to children were all independently associated with greater wellbeing whereas actual support to children was associated with lower wellbeing. Low received support from children interacted with paralysis in being especially associated with low wellbeing. In this Thai setting, as found in western settings, most of the association between physical impairments and lower wellbeing is explained by disability. Disability is potentially mediating the association between impairment and low wellbeing. Received support may buffer the impact of some impairments on wellbeing in this setting. Giving actual support to children is associated with less wellbeing unless the support being given to children is perceived as good, perhaps reflecting parental obligation to support adult children in need. Improving community disability services for older people and optimizing received social support will be vital in rural areas in developing countries.

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

PubMed

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 problems that limit the medical or surgical treatment options, botulinum toxin therapy represents a useful alternative. (C) 2013 Otology & Neurotology, Inc.

Periodic paralysis, cardiac arrhythmia and bone features are the hallmark of Andersen's syndrome (AS), a rare disorder caused by mutations in the KCNJ2 gene that encodes for the inward rectifier K(+)-channel Kir2.1. Rest following strenuous physical activity, carbohydrate ingestion, emotional stress and exposure to cold are the precipitating triggers. Most of the mutations act in a dominant-negative fashion, either through a trafficking dysfunction or through Kir2.1-phosphatidyl inositol bisphosphate binding defect. We have identified two families that were diagnosed with periodic paralysis and cardiac abnormalities, but only discrete development features. The proband in one of the two families reported having his symptoms occurring twice within the day following corticosteroids ingestion, and alleviated after stopping the corticosteroid treatment. Electromyographic evaluations pointed out to a typical hypokalemic periodic paralysis pattern. Molecular screening of the KCNJ2 gene identified two mutations leading to C54F and T305P substitutions in the Kir2.1 protein. Functional expression in mammalian cells revealed a loss-of-function of the mutated channels and a dominant-negative effect when both mutants and wild-type channels are present in the same cell. However, channel trafficking and assembly are not affected. Substitutions at these residues may interfere with phosphatidyl inositol bisphosphate binding to Kir2.1 channels. Sensitivity of our patients to multiple corticosteroid administrations shows that care must be taken in the use of such treatments in AS patients. Taken together, our data suggest the inclusion of the KCNJ2 gene in the molecular screening of patients with periodic paralysis, even when the classical AS dysmorphic features are not present.

To analyze the long-term objective, perceptive, and subjective outcomes after endoscopic polydimethylsiloxane (PDMS) injection laryngoplasty in unilateral vocal fold paralysis. 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 < 0.01) for all of the objective, perceptive, and subjective parameters by comparison between the preoperative and long-term follow-up data; moreover, no statistically significant difference was found between the postoperative and long-term follow-up data. This indicates that 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.

It is well accepted that recurrent laryngeal nerve paralysis is a severe complication of esophagectomy or lymphadenectomy performed adjacent to the recurrent laryngeal nerves. Herein, determination of the effectiveness of implementing continuous recurrent laryngeal nerve monitoring to reduce the incidence of recurrent laryngeal nerve paralysis after esophagectomy was sought. A total of 115 patients diagnosed with esophageal cancer were enrolled in the thoracic section of the Tangdu Hospital of the Fourth Military Medical University from April 2008 to April 2009. Clinical parameters of patients, the morbidity, and the mortality following esophageal resection were recorded and compared. After the surgery, a 2-year follow up was completed. It was found that recurrent laryngeal nerve paralysis and postoperative pneumonia were more frequently diagnosed in the patients that did not receive continuous recurrent laryngeal nerve monitoring (6/61 vs. 0/54). Furthermore, positive mediastinal lymph nodes (P = 0.015), total mediastinal lymph nodes (P < 0.001), positive total lymph nodes (P = 0.027), and total lymph nodes (P < 0.001) were more often surgically removed in the patients with continuous recurrent laryngeal nerve monitoring. These patients also had a higher 2-year survival rate (P = 0.038) after surgery. It was concluded that continuous intraoperative recurrent laryngeal nerve monitoring is technically safe and effectively identifies the recurrent laryngeal nerves. This may be a helpful method for decreasing the incidence of recurrent laryngeal nerve paralysis and postoperative pneumonia, and for improving the efficiency of lymphadenectomy. © 2012 Copyright the Authors.

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.

Acute paralysis following "a bad potato": a case of botulism.

Intensivists often encounter patients with respiratory failure as a result of neuromuscular disease, however, acute neuro-muscular syndromes are less common. We present a case of food borne Clostridium botulism and discuss the diagnostic and therapeutic considerations. A 35-yr-old healthy male presented with abdominal pain and blurred vision 12 hr after ingesting a "bad" potato. During the next 17 hr, the patient demonstrated a gradual descending paralysis which ultimately resulted in no cranial nerve function and 0/5 strength in all extremities. Sensation was intact. The patient required intubation and mechanical ventilation. His blood count, biochemical profile, computerized tomography and magnetic resonance imaging of the head were normal. A lumbar puncture revealed no abnormalities. Due to the rapid deterioration and presentation of 'descending' paralysis, botulism was suspected. The patient was treated empirically with botulinum anti-toxin. Samples of blood, stool and gastric contents were cultured for the presence of Clostridium botulinum and its toxin and these tests were positive for botulinum toxin A 12 days later. The patient's neuromuscular function gradually improved over a prolonged period of time. Six and one-half months after his initial presentation, the patient was discharged home after completing an aggressive rehabilitation program. Botulism is a rare syndrome and presents as an acute, afebrile, descending paralysis beginning with the cranial nerves. If suspected, botulinum anti-toxin should be considered, particularly within the first 24 hr of onset of symptoms. Confirmation of the presence of botulinum requires days therefore the diagnosis and management rely on history and physical examination.

Facial nerve palsy after reactivation of herpes simplex virus type 1 in diabetic mice.

Bell's palsy is highly associated with diabetes mellitus (DM). Either the reactivation of herpes simplex virus type 1 (HSV-1) or diabetic mononeuropathy has been proposed to cause the facial paralysis observed in DM patients. However, distinguishing whether the facial palsy is caused by herpetic neuritis or diabetic mononeuropathy is difficult. We previously reported that facial paralysis was aggravated in DM mice after HSV-1 inoculation of the murine auricle. In the current study, we induced HSV-1 reactivation by an auricular scratch following DM induction with streptozotocin (STZ). Controlled animal study. Diabetes mellitus was induced with streptozotocin injection in only mice that developed transient facial nerve paralysis with HSV-1. Recurrent facial palsy was induced after HSV-1 reactivation by auricular scratch. After DM induction, the number of cluster of differentiation 3 (CD3)(+) T cells decreased by 70% in the DM mice, and facial nerve palsy recurred in 13% of the DM mice. Herpes simplex virus type 1 deoxyribonucleic acid (DNA) was detected in the facial nerve of all of the DM mice with palsy, and HSV-1 capsids were found in the geniculate ganglion using electron microscopy. Herpes simplex virus type 1 DNA was also found in some of the DM mice without palsy, which suggested the subclinical reactivation of HSV-1. These results suggested that HSV-1 reactivation in the geniculate ganglion may be the main causative factor of the increased incidence of facial paralysis in DM patients. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

A sodium channel knockin mutant (NaV1.4-R669H) mouse model of hypokalemic periodic paralysis

Hypokalemic periodic paralysis (HypoPP) is an ion channelopathy of skeletal muscle characterized by attacks of muscle weakness associated with low serum K+. HypoPP results from a transient failure of muscle fiber excitability. Mutations in the genes encoding a calcium channel (CaV1.1) and a sodium channel (NaV1.4) have been identified in HypoPP families. Mutations of NaV1.4 give rise to a heterogeneous group of muscle disorders, with gain-of-function defects causing myotonia or hyperkalemic periodic paralysis. To address the question of specificity for the allele encoding the NaV1.4-R669H variant as a cause of HypoPP and to produce a model system in which to characterize functional defects of the mutant channel and susceptibility to paralysis, we generated knockin mice carrying the ortholog of the gene encoding the NaV1.4-R669H variant (referred to herein as R669H mice). Homozygous R669H mice had a robust HypoPP phenotype, with transient loss of muscle excitability and weakness in low-K+ challenge, insensitivity to high-K+ challenge, dominant inheritance, and absence of myotonia. Recovery was sensitive to the Na+/K+-ATPase pump inhibitor ouabain. Affected fibers had an anomalous inward current at hyperpolarized potentials, consistent with the proposal that a leaky gating pore in R669H channels triggers attacks, whereas a reduction in the amplitude of action potentials implies additional loss-of-function changes for the mutant NaV1.4 channels.

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.

Poliomyelitis is still an endemic disease in many areas of the world including Africa and South Asia. Iran is polio free since 2001. However, due to endemicity of polio in neighboring countries of Iran, the risk of polio importation and re-emergence of wild polio virus is high. Case definition through surveillance system is a well-defined method for maintenance of polio eradication in polio free countries. In a cross-sectional survey from 2007 to 2013, we reviewed all the records of under 15 years old patients reported to Acute Flaccid Paralysis Committee (AFPC) in Isfahan province, Iran. All cases were visited by members of the AFPC. Three stool samples were collected from each reported case within 2 weeks of onset of paralysis and sent to National Polio Laboratory in Tehran, Iran, for poliovirus isolation. Data were analyzed by SSPS software (version 22). Student's t-test and Chi-square was used to compare variables. Statistical significance level was set at P < 0.05. In this 6-year period 85 cases were analyzed, 54 patients were male (63.5%) and 31 were female (36.5%). The mean age of patients was 5.7 ± 3.9 years. The most common cause of paralysis among these patients was Guillian-Barré syndrome (83.5%). We did not found any poliomyelitis caused by wild polio virus. Only one case of vaccine associated poliomyelitis was reported. Since 1992, Iran has a routine and high percent coverage of polio vaccination program for infants (>94%), with six doses of oral polio vaccine (OPV). Accurate surveillance for poliomyelitis is essential for continuing eradication.

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).

Advances in high-performance computing are enabling a new generation of software tools that employ computational modeling for surgical planning. Surgical management of laryngeal paralysis is one area where such computational tools could have a significant impact. The current paper describes a comprehensive effort to develop a software tool for planning medialization laryngoplasty where a prosthetic implant is inserted into the larynx in order to medialize the paralyzed vocal fold (VF). While this is one of the most common procedures used to restore voice in patients with VF paralysis, it has a relatively high revision rate, and the tool being developed is expected to improve surgical outcomes. This software tool models the biomechanics of airflow-induced vibration in the human larynx and incorporates sophisticated approaches for modeling the turbulent laryngeal flow, the complex dynamics of the VFs, as well as the production of voiced sound. The current paper describes the key elements of the modeling approach, presents computational results that demonstrate the utility of the approach and also describes some of the limitations and challenges.

[Regeneration and repair of peripheral nerves: clinical implications in facial paralysis surgery].

PubMed

Hontanilla, B; Vidal, A

2000-01-01

Peripheral nerve lesions are one of the most frequent causes of chronic incapacity. Upper or lower limb palsies due to brachial or lumbar plexus injuries, facial paralysis and nerve lesions caused by systemic diseases are one of the major goals of plastic and reconstructive surgery. However, the poor results obtained in repaired peripheral nerves during the Second World War lead to a pessimist vision of peripheral nerve repair. Nevertheless, a well understanding of microsurgical principles in reconstruction and molecular biology of nerve regeneration have improved the clinical results. Thus, although the results obtained are quite far from perfect, these procedures give to patients a hope in the recuperation of their lesions and then on function. Technical aspects in nerve repair are well established; the next step is to manipulate the biology. In this article we will comment the biological processes which appear in peripheral nerve regeneration, we will establish the main concepts on peripheral nerve repair applied in facial paralysis cases and, finally, we will proportionate some ideas about how clinical practice could be affected by manipulation of the peripheral nerve biology.

2005-03-01

To investigate the prevalence and illness beliefs of sleep paralysis (SP) among Chinese patients in a psychiatric out-patient clinic, consecutive Chinese/Chinese-American patients who attended psychiatric out-patient clinics in Boston and Shanghai were asked about their lifetime prevalence, personal experience and perceptions regarding the causes, precipitating factors, consequences, and help-seeking of SP. During the 4-month study period, 42 non-psychotic psychiatric out-patients from the Boston site and 150 patients from the Shanghai site were interviewed. The prevalence of SP was found to be 26.2% in Boston and 23.3% in Shanghai. Patients with post-traumatic stress disorder (PTSD) or panic disorder reported a higher prevalence of SP than did patients without these disorders. Patients attributed SP to fatigue, stress, and other psychosocial factors. Although the experience has traditionally been labeled 'ghost oppression' among the Chinese, only two patients, one from each site, endorsed supernatural causes of their SP. Sleep paralysis is common among Chinese psychiatric out-patients. The endorsement of supernatural explanations for SP is rare among contemporary Chinese patients.

The aim of our case study is to illustrate diagnostic and therapeutic difficulties as well as gravity related to tuberculous otitis media with intracranial complications. A diabetic male patient of 65 years old was treated for subacute otitis media with mixed hearing loss. Early bacteriologic samples from ear exudates revealed opportunistic pathogens. Clinical evolution after four months was marked by the appearance of mastoiditis with facial paralysis. The patient presented petrositis and bilateral laryngeal paralysis with lymphocytic meningitis after six and eight months respectively. Tuberculosis was suspected after a positive ELlspot tests with appearance of biologic markers of hepatic dysfunction like cholestasis and hepatic cytolysis. Although antituberculous treatment was instaured even without isolation of acid fast bacilli, the patient died after ten months. Subacute otitis media complicated by labyrinthitis, early onset of facial paralysis or any other oranial nerve palsy should raise suspicion of tuberculosis. The prognosis depends on early diagnosis which remains difficult despite morphological and metabolic imaging. The diagnostic workup should include histological and bacteriologic samples, liver markers of intacellular damage as well as ELlspot test. The prognosis remains poor especially in immunocompromised patients despite appropriate treatment.

At least 18 viruses have been reported in the honey bee (Apis mellifera L.). However, severe diseases in honey bees are mainly caused by six viruses, and these are the most important in beekeeping. These viruses include: deformed wing virus (DWV), acute bee paralysis virus (ABPV), chronic bee paralysis virus (CBPV), sacbrood virus (SBV), kashmir bee virus (KBV), and black queen cell virus (BQCV). In this study, we evaluated 89 Iranian honey bee apiaries (during the period 2015-2016) suffering from symptoms of depopulation, sudden collapse, paralysis, or dark coloring, by employing reverse transcription-PCR. Samples were collected from four regions (Mazandaran, Hormozgan, Kurdistan, and Khorasan Razavi) of Iran. Of the 89 apiaries examined, 16 (17.97%), three (3.37%), and three (3.37%) were infected by DWV, ABPV, and CBPV, respectively. The study results for the other viruses (SBV, KBV, and BQCV) were negative. The present study evaluated the presence of the six most important honey bee viruses in bee colonies with suspected infections, and identified remarkable differences in the distribution patterns of the viruses in different geographic regions of Iran.

Non-functioning parathyroid adenoma: a rare differential diagnosis for vocal-cord paralysis

Kamali, D; Sharpe, A; Nagarajan, S; Elsaify, W

2016-01-01

Introduction Adenomas of the parathyroid gland typically present with symptoms of hyperparathyroidism, manifested by fatigue, bone pain, abdominal pain, weakness, dyspepsia, nephrolithiasis and skeletal bone disease. Here, we describe, for the first time, a case of a non-functioning benign tumour of the parathyroid gland presenting as vocal-cord paralysis. Case History A 49-year-old male presented with a 10-week history of dysphonia and the feeling of having ‘something stuck in my throat’. History-taking elicited no other associated symptoms. Flexible nasal endoscopy demonstrated paralysis of the left vocal cord. Computed tomography of the neck revealed a cystic lesion, 18mm in diameter adjacent to the oesophagus. After more rigorous tests, a neck exploration, left hemithyroidectomy, excision of the left paratracheal mass and level-VI neck dissection was undertaken, without incident to the patient or surgical team. Histology was consistent with a parathyroid adenoma. Conclusions This case emphasises the importance of including adenomatous disease of the parathyroid gland in the differential diagnosis despite normal parathyroid status as a cause of vocal cord palsy.

2012-03-01

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 skin on the face is directly attached to the underlying muscles. Here, we successfully introduce a non-invasive, non-contact technique, Digital Image Speckle Correlation (DISC), to measure the precise magnitude and duration of facial muscle paralysis inflicted by BTX-A. Subjective evaluation by clinicians and patients fail to objectively quantify the direct effect and duration of BTX-A on the facial musculature. By using DISC, we can (a) Directly measure deformation field of the facial skin and determine the locus of facial muscular tension(b)Quantify and monitor muscular paralysis and subsequent re-innervation following injection; (c) Continuously correlate the appearance of wrinkles and muscular tension. Two sequential photographs of slight facial motion (frowning, raising eyebrows) are taken. DISC processes the images to produce a vector map of muscular displacement from which spatially resolved information is obtained regarding facial tension. DISC can track the ability of different muscle groups to contract and can be used to predict the site of injection, quantify muscle paralysis and the rate of recovery following BOTOX injection.

Transgenic mice bearing the human poliovirus receptor (TgPVR) are less susceptible to oral inoculation, although they are susceptible to parenteral inoculation. We investigated the susceptibility of TgPVR 21 line [Arch. Virol. 130 (1994) 351] to poliovirus through various mucosal routes. Intranasal inoculation of a neurovirulent Mahoney strain (OM1) caused flaccid paralysis with viral replication in the central nervous system at a dose of 10(6) cell culture infectious dose (CCID50), in contrast, no paralysis following oral or intragastric inoculation of the same dose. Intranasal inoculation of a vaccine strain, Sabin 1, at 10(6) CCID50, resulted in no paralysis. Initial replication of poliovirus in the nasal cavity was confirmed by virus isolation and detection of negative-stranded replicative intermediates by RT-PCR and viral antigens using a high-sensitive immunohistochemistry and genome/transcripts by in situ hybridization. Poliovirus-specific IgG antibodies were elevated in the sera of surviving TgPVR21. This model can be used as a mucosal infection model and for differentiation of neurovirulent and attenuated poliovirus strains.

2015-01-01

People with facial paralysis (FP) report social difficulties, but some attempt to compensate by increasing expressivity in their bodies and voices. We examined perceivers’ emotion judgments of videos of people with FP to understand how they interpret the combination of an inexpressive face with an expressive body and voice. Results suggest perceivers form less favorable impressions of people with severe FP, but compensatory expression is effective in improving impressions. Perceivers seemed to form holistic impressions when rating happiness and possibly sadness. Findings have implications for basic emotion research and social functioning interventions for people with FP. PMID:26412919

Anesthesia and surgery in a Quarter Horse affected with hyperkalemic periodic paralysis resulted in euthanasia after 7 days of postoperative recumbency. Initial recovery was uneventful after extensive sinus surgery, but within 2 hours, the horse had severe muscle weakness. Plasma electrolyte concentrations were within the normal range during the period of recumbency. There was no clinical or laboratory evidence of severe muscle damage. Despite treatment with acetazolamide, isoproterenol, and intensive nursing, the horse was unable to stand for more than a few seconds and developed severe decubital ulcers. Ultrastructural examination revealed nemaline rods and swollen mitochondria in disrupted myofibers.

In the modern medical era, facial paralysis is linked with the name of Charles Bell. This disease, which is usually unilateral and is a peripheral facial palsy, causes facial muscle weakness in the affected side. Bell gave a complete description of the disease; but historically other physicians had described it several hundred years prior although it had been ignored for different reasons, such as the difficulty of the original text language. The first and the most famous of these physicians who described this disease was Mohammad Ibn Zakaryya Razi (Rhazes). In this article, we discuss his opinion.

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.

SUMMARY 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 20th 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 20th 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. For a comprehensive treatment of the paralysis, the eyelids are usually managed by Paul Tessier's technique to lengthen the levator muscle of the upper eyelid by aponeurosis interposition, combined with external blepharorrhaphy with Krastinova-Lolov's technique. Facial reanimation using lengthening temporalis myoplasty is a dynamic procedure that has its roots in the techniques of Gillies and McLaughlin. This method is a true lengthening myoplasty procedure using no intermediate grafts. In general, the results with a 1-stage combination of lengthening temporalis myoplasty and static correction of the lagophthalmos appear comparable with the major series in the literature using free microneurovascular transfers combined with cross-facial nerve grafts for longstanding peripheral monolateral facial paralysis. The obvious advantages of temporalis elongation myoplasty consist in its technical ease, a single step, low incidence of complications and markedly reduced operating time. PMID:22767978

The role of nerve monitoring to predict postoperative recurrent laryngeal nerve function in thyroid and parathyroid surgery.

To determine the role and efficacy of intraoperative recurrent laryngeal nerve (RLN) stimulation in the prediction of early and permanent postoperative nerve function in thyroid and parathyroid surgery. A retrospective review of thyroid and parathyroid surgeries was performed with calculation of sensitivity and specificity of the response of intraoperative stimulation for different pathological groups. Normal electromyography (EMG) response with 0.5 mAmp stimulation was considered a positive stimulation response with postoperative function determined by laryngoscopy. No EMG response at >1-2 mAmps was considered a negative response. The rates of early and permanent paralysis, as well as sensitivity, specificity, and positive and negative predictive values for postoperative nerve function were calculated for separate pathological groups. The number of nerves at risk analyzed was 909. The overall early and permanent paralysis rates were 3.1% and 1.2%, respectively, with the highest rate being for Grave's disease cases. The overall sensitivity was 98.4%. The specificity was lower at 62.5% but acceptable in thyroid carcinoma and Grave's disease patients. The majority of nerves with a positive stimulation result and postoperative paralysis on laryngoscopy recovered function in 3 to 12 weeks, showing positive stimulation to be a good predictor of eventual recovery. Stimulation of the RLN during thyroid and parathyroid surgery is a useful tool in predicting postoperative RLN function. The sensitivity of stimulation is high, showing positive stimulation to be an excellent predictor of normal nerve function. Negative stimulation is more predictive of paralysis in cases of thyroid carcinoma and Grave's disease. 2b. Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

Vocal cord paralysis (VCP) is a serious complication associated with thoracic aortic surgery; however, there is a paucity of literature regarding the incidence and impact of VCP on postoperative outcomes. We sought to determine the incidence of VCP and its impact on clinical outcomes in patients who underwent thoracic aortic repair at our center. A retrospective chart review was conducted on all patients who underwent thoracic aortic surgery between January 2009 and September 2012. A total of 259 patients underwent a thoracic aortic procedure during the study period. Vocal cord paralysis was diagnosed in 12 (5%) patients, a median of 6 [3 to 21] days after extubation. The incidence was 1%, 0%, 20%, and 25% in those undergoing an open ascending, hemiarch, total arch, or descending aortic procedure, respectively. Patients with VCP had an increased incidence of pneumonia (58% vs 17%, p = 0.003), readmission to the intensive care unit for respiratory failure (17% vs 2%, p = 0.047), and longer hospital length of stay (18 [11 to 43] days versus 9 [6 to 15] days, p = 0.002). A propensity-matched analysis confirmed a higher incidence of pneumonia (58% vs 17%, p = 0.020) and longer hospital length of stay (18 [11 to 43] vs 10 [7 to 14] days, p = 0.015) in patients suffering VCP. Vocal cord paralysis is a common complication in patients undergoing open surgery of the aortic arch and descending aorta, and is associated with significant morbidity. Further research may be warranted to determine if early fiberoptic examination and consideration of a vocal cord medialization procedure may mitigate the morbidity associated with VCP.

A mouse model of paralytic myelitis caused by enterovirus D68

2017-01-01

In 2014, the United States experienced an epidemic of acute flaccid myelitis (AFM) cases in children coincident with a nationwide outbreak of enterovirus D68 (EV-D68) respiratory disease. Up to half of the 2014 AFM patients had EV-D68 RNA detected by RT-PCR in their respiratory secretions, although EV-D68 was only detected in cerebrospinal fluid (CSF) from one 2014 AFM patient. Given previously described molecular and epidemiologic associations between EV-D68 and AFM, we sought to develop an animal model by screening seven EV-D68 strains for the ability to induce neurological disease in neonatal mice. We found that four EV-D68 strains from the 2014 outbreak (out of five tested) produced a paralytic disease in mice resembling human AFM. The remaining 2014 strain, as well as 1962 prototype EV-D68 strains Fermon and Rhyne, did not produce, or rarely produced, paralysis in mice. In-depth examination of the paralysis caused by a representative 2014 strain, MO/14-18947, revealed infectious virus, virion particles, and viral genome in the spinal cords of paralyzed mice. Paralysis was elicited in mice following intramuscular, intracerebral, intraperitoneal, and intranasal infection, in descending frequency, and was associated with infection and loss of motor neurons in the anterior horns of spinal cord segments corresponding to paralyzed limbs. Virus isolated from spinal cords of infected mice transmitted disease when injected into naïve mice, fulfilling Koch’s postulates in this model. Finally, we found that EV-D68 immune sera, but not normal mouse sera, protected mice from development of paralysis and death when administered prior to viral challenge. These studies establish an experimental model to study EV-D68-induced myelitis and to better understand disease pathogenesis and develop potential therapies. PMID:28231269

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

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.

Effect of intralaryngeal muscle synkinesis on perception of voice handicap in patients with unilateral vocal fold paralysis.

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.

Another Scale for the Assessment of Facial Paralysis? ADS Scale: Our Proposition, How to Use It.

Di Stadio, Arianna

2015-12-01

Several authors in the years propose different methods to evaluate areas and specific movement's disease in patient affected by facial palsy. Despite these efforts the House Brackmann is anyway the most used assessment in medical community. The aims of our study is the proposition and assessing a new rating Arianna Disease Scale (ADS) for the clinical evaluation of facial paralysis. Sixty patients affected by unilateral facial Bell paralysis were enrolled in a prospective study from 2012 to 2014. Their facial nerve function was evaluated with our assessment analysing facial district divided in upper, middle and lower third. We analysed different facial expressions. Each movement corresponded to the action of different muscles. The action of each muscle was scored from 0 to 1, with 0 corresponding from complete flaccid paralysis to muscle's normal function ending with a score of 1. Synkinesis was considered and evaluated also in the scale with a fixed 0.5 score. Our results considered ease and speed of evaluation of the assessment, the accuracy of muscle deficit and the ability to calculate synkinesis using a score. All the three observers agreed 100% in the highest degree of deficit. We found some discrepancies in intermediate score with 92% agreement in upper face, 87% in middle and 80% in lower face, where there were more muscles involved in movements. Our scale had some limitations linked to the small group of patients evaluated and we had a little difficulty understanding the intermediate score of 0.3 and 0.7. However, this was an accurate tool to quickly evaluate facial nerve function. This has potential as an alternative scale to and to diagnose facial nerve disorders.

To assess and grade facial nerve dysfunction according to the extent of facial paralysis in the clinical course of acupuncture treatment for Bell's palsy, and to observe the interrelationship between the grade, the efficacy and the period of treatment, as well as the effect on prognosis. The authors employed the House-Brackmann scale, a commonly used evaluation scale for facial paralysis motor function, and set standards for eye fissure and lips. According to the improved scale, the authors assessed and graded the degree of facial paralysis in terms of facial nerve dysfunction both before and after treatment. The grade was divided into five levels: mild, moderate, moderately severe, severe dysfunction and complete paralysis. The authors gave acupuncture treatment according to the state of the disease without artificially setting the treatment period. The observation was focused on the efficacy and the efficacy was evaluated throughout the entire treatment process. Fifty-three cases out of 68 patients with Bell's palsy were cured and the overall rate of efficacy was 97%. Statistically significant differences (P<0.01) were perceived among the efficacy of five levels of facial nerve dysfunction. Efficacy was correlated with the damage level of the disease (correlation coefficient r=0.423, P<0.01). The course of treatment also extended with the severity of facial nerve dysfunction (P<0.01). Differences exist in patients with Bell's palsy in terms of severity of facial nerve dysfunction. Efficacy is reduced in correlation with an increase in facial nerve dysfunction, and the period of treatment varies in need of different levels of facial nerve dysfunction. It is highly necessary to assess and grade patients before observation and treatment in clinical study, and choose corresponding treatment according to severity of damage of the disease.

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.

Lesions of the temporal bone and cerebellopontine angle and their management can result in facial nerve paralysis. When the nerve deficit is not amenable to primary end-to-end repair or interpositional grafting, nerve transposition can be used to accomplish the goals of restoring facial tone, symmetry, and voluntary movement. The most widely used nerve transposition is the hypoglossal-facial nerve anastamosis, of which there are several technical variations. Previously we described a technique of single end-to-side anastamosis using intratemporal facial nerve mobilization and parotid release. This study further characterizes the results of this technique with a larger patient cohort and longer-term follow-up. The design of this study is a retrospective chart review and the setting is an academic tertiary care referral center. Twenty-one patients with facial nerve paralysis from proximal nerve injury at the cerebellopontine angle underwent facial-hypoglossal neurorraphy with parotid release. Outcomes were assessed using the Repaired Facial Nerve Recovery Scale, questionnaires, and patient photographs. Of the 21 patients, 18 were successfully reinnervated to a score of a B or C on the recovery scale, which equates to good oral and ocular sphincter closure with minimal mass movement. The mean duration of paralysis between injury and repair was 12.1 months (range 0 to 36 months) with a mean follow-up of 55 months. There were no cases of hemiglossal atrophy, paralysis, or subjective dysfunction. Direct facial-hypoglossal neurorrhaphy with parotid release achieved a functional reinnervation and good clinical outcome in the majority of patients, with minimal lingual morbidity. This technique is a viable option for facial reanimation and should be strongly considered as a surgical option for the paralyzed face. PMID:22451794

This study describes the technique and evaluates the outcome of the triple-tendon (T3) transfer, an Eden-Lange variant, to the scapula to stabilize the scapulothoracic articulation in the treatment of symptomatic trapezius paralysis. T3 transfers were performed in 22 patients with a history of persistent trapezius paralysis secondary to spinal accessory nerve injury. The indications for surgery included shoulder pain and weakness and limited range of motion of the shoulder. The T3 transfer included transfer of the levator scapulae to the lateral aspect of the spine of the scapula, the rhomboid minor to the spine of the scapula just medial to the levator scapulae insertion, and the rhomboid major to the medial spine of the scapula, including all muscles bony insertions. At an average follow-up of 35 months, winging was corrected in all patients, with improvement of shoulder asymmetry. All patients had significant improvement of pain (P < .01) and range of motion, including active shoulder abduction that improved from an average of 71° preoperatively to 118° postoperatively (P < .02) and shoulder flexion from an average of 102° to 150° (P < .01). There were also significant improvements in aggregate Constant Shoulder Score (P < .01), subjective shoulder value (P < .01), and Disabilities of the Arm, Shoulder and Hand score (P < .01). All patients were very satisfied with the outcome of surgery. This study shows that the T3 transfer is effective in stabilizing the scapulothoracic articulation and restoring the function of the trapezius, and thus, in improving pain and shoulder function in patients with symptomatic trapezius paralysis.

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.

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.

The insulin-sensitivity sulphonylurea receptor variant is associated with thyrotoxic paralysis.

Thyrotoxicosis is the most common cause of the acquired flaccid muscle paralysis in adults called thyrotoxic periodic paralysis (TPP) and is characterised by transient hypokalaemia and hypophosphataemia under high thyroid hormone levels that is frequently precipitated by carbohydrate load. The sulphonylurea receptor 1 (SUR1 (ABCC8)) is an essential regulatory subunit of the β-cell ATP-sensitive K(+) channel that controls insulin secretion after feeding. Additionally, the SUR1 Ala1369Ser variant appears to be associated with insulin sensitivity. We examined the ABCC8 gene at the single nucleotide level using PCR-restriction fragment length polymorphism (RFLP) analysis to determine its allelic variant frequency and calculated the frequency of the Ala1369Ser C-allele variant in a cohort of 36 Brazilian TPP patients in comparison with 32 controls presenting with thyrotoxicosis without paralysis (TWP). We verified that the frequency of the alanine 1369 C-allele was significantly higher in TPP patients than in TWP patients (61.1 vs 34.4%, odds ratio (OR)=3.42, P=0.039) and was significantly more common than the minor allele frequency observed in the general population from the 1000 Genomes database (61.1 vs 29.0%, OR=4.87, P<0.005). Additionally, the C-allele frequency was similar between TWP patients and the general population (34.4 vs 29%, OR=1.42, P=0.325). We have demonstrated that SUR1 alanine 1369 variant is associated with allelic susceptibility to TPP. We suggest that the hyperinsulinaemia that is observed in TPP may be linked to the ATP-sensitive K(+)/SUR1 alanine variant and, therefore, contribute to the major feedforward precipitating factors in the pathophysiology of TPP. © 2014 Society for Endocrinology.

Background: Poliomyelitis is still an endemic disease in many areas of the world including Africa and South Asia. Iran is polio free since 2001. However, due to endemicity of polio in neighboring countries of Iran, the risk of polio importation and re-emergence of wild polio virus is high. Case definition through surveillance system is a well-defined method for maintenance of polio eradication in polio free countries. Methods: In a cross-sectional survey from 2007 to 2013, we reviewed all the records of under 15 years old patients reported to Acute Flaccid Paralysis Committee (AFPC) in Isfahan province, Iran. All cases were visited by members of the AFPC. Three stool samples were collected from each reported case within 2 weeks of onset of paralysis and sent to National Polio Laboratory in Tehran, Iran, for poliovirus isolation. Data were analyzed by SSPS software (version 22). Student's t-test and Chi-square was used to compare variables. Statistical significance level was set at P < 0.05. Results: In this 6-year period 85 cases were analyzed, 54 patients were male (63.5%) and 31 were female (36.5%). The mean age of patients was 5.7 ± 3.9 years. The most common cause of paralysis among these patients was Guillian–Barré syndrome (83.5%). We did not found any poliomyelitis caused by wild polio virus. Only one case of vaccine associated poliomyelitis was reported. Conclusion: Since 1992, Iran has a routine and high percent coverage of polio vaccination program for infants (>94%), with six doses of oral polio vaccine (OPV). Accurate surveillance for poliomyelitis is essential for continuing eradication. PMID:26015925

Ixodes holocyclus, the eastern paralysis tick, is a significant parasite in Australia in terms of animal and human health. However, very little is known about its virome. In this study, next-generation sequencing of I. holocyclus salivary glands yielded a full-length genome sequence which phylogenetically groups with viruses classified in the Iflaviridae family and shares 45% amino acid similarity with its closest relative Bole hyalomma asiaticum virus 1. The sequence of this virus, provisionally named Ixodes holocyclus iflavirus (IhIV) has been identified in tick populations from northern New South Wales and Queensland, Australia and represents the first virus sequence reported from I. holocyclus.

Facial paralysis can result in serious ocular consequences. All patients with orbicularis oculi weakness in the setting of facial nerve injury should undergo a thorough ophthalmologic evaluation. The main goal of management in these patients is to protect the ocular surface and preserve visual function. Patients with expected recovery of facial nerve function may only require temporary and conservative measures to protect the ocular surface. Patients with prolonged or unlikely recovery of facial nerve function benefit from surgical rehabilitation of the periorbital complex. Current reconstructive procedures are most commonly intended to improve coverage of the eye but cannot restore blink. Copyright © 2016 Elsevier Inc. All rights reserved.

The supernatural fears associated with the experience of isolated sleep paralysis in the culture of developing countries is sometimes associated with the evolution of somatic symptoms of psychological origin in patients predisposed to neurotic illness. Patients rarely spontaneously volunteer these fears and doctors pay them scant attention. Illustrative case histories that demonstrate the dynamics of the clinical presentation, as well as the treatment approach, are highlighted. It is hoped that doctors in general medical practice and in psychological medicine in developing countries where belief in supernatural causation of illness is rife will consider these factors in order to provide more effective treatment.

Bilateral facial paralysis is an uncommon clinical entity especially in the pediatric age group and occurs frequently as a manifestation of systemic disease. The most important causes are trauma, infectious diseases, neurological diseases, metabolic, neoplastic, autoimmune diseases and idiopathic disease (Bell's palsy). We report a case of an 11-year-old boy presenting with bilateral simultaneous peripheral facial paralysis. All possible infectious causes were excluded and the patient was diagnosed as having Bell's palsy (idiopathic). The most important approach in these cases is to rule out a life-threatening disease. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

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.

The Bell's palsy (G51) consists of a unilateral face paralysis that sudden begins with unknown cause and can result in complete mimic loss or partial paralysis of the face. Damage to the VII cranial nerve can be found in the pathology, promoting mussel's inactivity. The light Photobiomodulation (LPBM) has presented ability of rush the tissue repair, favoring the regeneration of neural structures. The present study aimed to assess the effectiveness use of the 780nm laser and 850nm LED (light-emitting diode) in the treatment of the face paralysis. Were evaluated 14 patients that suffer of Bell's palsy whom were submitted to the light administration, on the Laser Clinic of the UFBA between 2005 and 2010. The treatment was performed by infrared Laser in 11 patients (78.57%), and by LED in 3 patients (21.42%). At the end of the 12 sections, 11 patients (78.57%) had presented themselves cure or with substantial improvement of the initial picture, however 3 patients (21.42%) dealt with infra-red Laser λ780nm had not evolution. The light presented as an effective method for the treatment of Bell's palsy, but the association with the physiotherapy and medications is important.

[Purpose] The motor paralysis-improving effect on the hemiplegic lower limb was compared among mirror therapy, integrated volitional-control electrical stimulation, therapeutic electrical stimulation, repetitive facilitative exercises, and the standard training method in post-stroke hemiplegia patients. [Subjects and Methods] Eighty one stroke patients admitted to a convalescent rehabilitation ward were randomly allocated to the above 5 treatment groups. Each patient performed functional training of the paralytic lower limb for 20 minutes a day for 4 weeks, and changes in the lower limb function were investigated using the Stroke Impairment Assessment Set. [Results] The hip and knee joint functions did not significantly improve in the standard training control group, but significant improvements were observed after 4 weeks in the other intervention groups. Significant improvement was noted in the ankle joint function in all groups. [Conclusion] Although the results were influenced by spontaneous recovery and the standard training in the control group, the hip and knee joints were more markedly improved by the interventions in the other 4 groups of patients with moderate paralysis, compared to the control group.

War, politics, and voice: the vocal fold paralysis of George Orwell.

Sulica, Lucian

2007-02-01

In 1936, like many individuals who felt the menace of fascism, George Orwell traveled to Spain to lend his support to the cause of the Republic, battling a right-wing coup. Spain, during its Civil War, was an eye-opening experience for him, yielding insights that allowed, and even compelled him to write Animal Farm and 1984. Spain was also a close brush with death. In May of 1937, in a trench on a windswept ridge near Huesca, Orwell was shot through the neck by a sniper, leaving him with a paralyzed vocal fold. A thorough review of firsthand accounts of Orwell's injury and subsequent care was made. These are presented in the context of current knowledge of ballistics, penetrating neck trauma, and vocal fold paralysis. Orwell survived largely because of the nature of his wounding with a high-velocity jacketed military round. His recovery followed a course in many ways typical for patients with vocal fold paralysis. His writings leave us a unique and extraordinary account of the experience of being shot, of the medical care of the day, of the handicap of paralytic dysphonia, and of survival and heroism under extraordinary circumstances.

[Facial paralysis in children].

Facial paralyses in children may be grouped under headings displaying a certain amount of individuality. Chronologically, first to be described are neonatal facial paralyses. These are common and are nearly always cured within a few days. Some of these cases are due to the mastoid being crushed at birth with or without the use of forceps. The intra-osseous pathway of the facial nerve is then affected throughout its length. However, a cure is often spontaneous. When this desirable development does not take place within three months, the nerve should be freed by decompressive surgery. The special anatomy of the facial nerve in the new-born baby makes this a delicate operation. Later, in all stages of acute otitis, acute mastoiditis or chronic otitis, facial paralysis can be seen. Treatment depends on the stage reached by the otitis: paracentesis, mastoidectomy, various scraping procedures, and, of course, antibiotherapy. The other causes of facial paralysis in children are very much less common: a frigore or viral, traumatic, occur ring in the course of acute poliomyelitis, shingles or tumours of the middle ear. To these must be added exceptional causes such as vitamin D intoxication, idiopathic hypercalcaemia and certain haemopathies.

Wasp uses venom cocktail to manipulate the behavior of its cockroach prey.

PubMed

Libersat, F

2003-07-01

The sting of the parasitoid wasp Ampulex compressa is unusual, as it induces a transient paralysis of the front legs followed by grooming behavior and then by a long-term hypokinesia of its cockroach prey. Because the wasp's goal is to provide a living meal for its newborn larva, the behavioral changes in the prey are brought about by manipulating the host behavior in a way beneficial to the wasp and its offspring. To this end, the wasp injects its venom cocktail with two consecutive stings directly into the host's central nervous system. The first sting in the thorax causes a transient front leg paralysis lasting a few minutes. This paralysis is due to the presence of a venom component that induces a postsynaptic block of central cholinergic synaptic transmission. Following the head sting, dopamine identified in the venom appears to induce 30 min of intense grooming. During the long-term hypokinesia that follows the grooming, specific behaviors of the prey are inhibited while others are unaffected. We propose that the venom represses the activity of head ganglia neurons thereby removing the descending excitatory drive to the thoracic neurons.

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.

Since 1997 National Institute of Virology, Bangalore Unit involved in WHO's Acute flaccid paralysis paediatric cases surveillance programme to isolate and detect polioviruses. Stool samples yielded not only polioviruses but also Non-Polio enteroviruses. This report is an overview of non-polio Enterovirus (NPEV) epidemiology in Karnataka state, India for the period of 16-years and 6 months from July 1997-2013. A total of 19,410 clinical samples were processed for virus isolation as a part of acute flaccid paralysis (AFP) surveillance for Global Polio Eradication Programme in India at National Polio Laboratory, at Bengaluru. NPEV detection was performed by virus isolation on cell culture according to World Health Organisation recommended protocols. A total of 4152 NPEV isolates were obtained. The NPEV isolation rate varied from year to year but with a total NPEV rate of 21.39%. A seasonal variation was noted with high transmission period between April and October with peaks in June-July. The male to female ratio was 1:1.2. The isolation of NPEV decreased significantly with the increase in age. Epidemiology of NPEVs from AFP cases in Karnataka is described.

Early effects of embryonic movement: ‘a shot out of the dark’

PubMed Central

Pitsillides, Andrew A

2006-01-01

It has long been appreciated that studying the embryonic chick in ovo provides a variety of advantages, including the potential to control the embryo's environment and its movement independently of maternal influences. This allowed early workers to identify movement as a pivotal factor in the development of the locomotor apparatus. With an increasing focus on the earliest detectable movements, we have exploited this system by developing novel models and schemes to examine the influence of defined periods of movement during musculoskeletal development. Utilizing drugs with known neuromuscular actions to provoke hyperactivity (4-aminopyridine, AP) and either rigid (decamethonium bromide, DMB) or flaccid (pancuronium bromide, PB) paralysis, we have examined the role of movement in joint, osteochondral and muscle development. Our initial studies focusing on the joint showed that AP-induced hyperactivity had little, if any, effect on the timing or scope of joint cavity elaboration, suggesting that endogenous activity levels provide sufficient stimulus, and additional mobilization is without effect. By contrast, imposition of either rigid or flaccid paralysis prior to cavity formation completely blocked this process and, with time, produced fusion of cartilaginous elements and formation of continuous single cartilaginous rods across locations where joints would ordinarily form. The effect of these distinct forms of paralysis differed, however, when treatment was initiated after formation of an overt cavity; rigid, but not flaccid, paralysis partly conserved precavitated joints. This observation suggests that ‘static’ loading derived from ‘spastic’ rigidity can act to preserve joint cavities. Another facet of these studies was the observation that DMB-induced rigid paralysis produces a uniform and specific pattern of limb deformity whereas PB generated a diverse range of fixed positional deformities. Both also reduced limb growth, with different developmental periods preferentially modifying specific osteochondral components. Changes in cartilage and bone growth induced by 3-day periods of flaccid immobilization, imposed at distinct developmental phases, provides support for a diminution in cartilage elaboration at an early phase and for a relatively delayed influence of movement on osteogenesis, invoking critical periods during which the developing skeleton becomes receptive to the impact of movement. Immobilization also exerts differential impact along the proximo-distal axis of the limb. Finally, our preliminary results support the possibility that embryonic hyperactivity influences the potential for postnatal muscle growth. PMID:16637868

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 < .001). Mean (SD) FACE scores 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 < .001; trigeminal innervation cohort, 38.9 [14.6] vs 55.2 [18.2]; P < .001; cross-face nerve graft cohort, 47.3 [16.6] vs 61.7 [16.9]; P < .001) except the failure cohort (36.5 [20.8] vs 33.5 [17.9]; Wilcoxon signed-rank test, P = .15). Analysis of 40 patients' photographs revealed a mean (SD) preoperative and postoperative excursion on the affected side of -0.88 (3.79) and 7.68 (3.38), respectively (P < .001); symmetry with smile improved from a mean (SD) of 13.8 (7.46) to 4.88 (3.47) (P < .001). Free gracilis muscle transfer has become a mainstay in the management armamentarium for patients with severe reduction in oral commissure movement after facial nerve insult and recovery. We found a quantitative 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.

Botulinum toxin injection in laryngeal dyspnea.

Data, regarding the use of botulinum toxin (BT-A) in laryngeal dyspnea, are scarce, coming from some cases reports in the literature, including Vocal fold paralysis, laryngeal dystonia, vocal cord dysfunction also called paradoxical motion of the vocal fold (PMVF), and post-neuroleptic laryngeal dyskinesia. There is no consensus regarding the muscles and the doses to inject. The aim of this study is to present a retrospective review of patients treated in our ENT Department by BT-A injection in this indication. This study is a retrospective study describing patients who underwent an injection of botulinum toxin for laryngeal dyspnea in the ENT Department from 2005 to 2015 years. The inclusion criteria were a dyspnea associated with a laryngeal dysfunction, confirmed by flexible fiberoptic nasopharyngolaryngoscopy. Information concerning the causes of the dyspnea, the botulinum toxin BT-A injections procedure, post-injection follow-up, and respiratory outcome were collected for all patients included. In the group of 13 patients included, the main cause identified as principal factor linked with the short breath was: a bilateral VF paralysis (Patel et al., Otolaryngol Head Neck Surg 130:686-689, 7), laryngeal dystonia (Balkissoon and Kenn, Semin Respir Crit Care Med 33:595-605, 2), Anxiety syndrome associated with unilateral vocal fold paralysis or asthma (Marcinow et al., Laryngoscope 124:1425-1430, 3), and an isolated asthma (Zwirner et al., Eur Arch Otorhinolaryngol 254:242-245, 1). Nine out of the thirteen patients were improved by the injections. A BT-A-induced stable benefit for four patients led them to stop the injections in the follow-up. Good outcome was observed in five other patients (main cause: bilateral VP paralysis), allowing a progressive lengthening of the delay between BT-A injections. Four patients did not report a positive risk/benefit ratio after BT-A injections; two of them (with bilateral VF paralysis), because of respiratory side effects and lack of benefit without the side effects for the two others. This failure of effect was not related with BT-A doses injected. This study provides support for using BT-A injections as a symptomatic treatment of periodic laryngeal dyspnea, regardless of the etiologic context. From our data, we suggest that a small starting dose (of around 4 U BT-A Botox ® ) could be enough for a first injection to obtain a good benefit. The target muscle should be determined by the EMG analysis.

Facial palsy or paralysis (FP) is a symptom that loses voluntary muscles movement in one side of the human face, which could be very devastating in the part of the patients. Traditional methods are solely dependent to clinician's judgment and therefore time consuming and subjective in nature. Hence, a quantitative assessment system becomes apparently invaluable for physicians to begin the rehabilitation process; and to produce a reliable and robust method is challenging and still underway. We introduce a novel approach for a quantitative assessment of facial paralysis that tackles classification problem for FP type and degree of severity. Specifically, a novel method of quantitative assessment is presented: an algorithm that extracts the human iris and detects facial landmarks; and a hybrid approach combining the rule-based and machine learning algorithm to analyze and prognosticate facial paralysis using the captured images. A method combining the optimized Daugman's algorithm and Localized Active Contour (LAC) model is proposed to efficiently extract the iris and facial landmark or key points. To improve the performance of LAC, appropriate parameters of initial evolving curve for facial features' segmentation are automatically selected. The symmetry score is measured by the ratio between features extracted from the two sides of the face. Hybrid classifiers (i.e. rule-based with regularized logistic regression) were employed for discriminating healthy and unhealthy subjects, FP type classification, and for facial paralysis grading based on House-Brackmann (H-B) scale. Quantitative analysis was performed to evaluate the performance of the proposed approach. Experiments show that the proposed method demonstrates its efficiency. Facial movement feature extraction on facial images based on iris segmentation and LAC-based key point detection along with a hybrid classifier provides a more efficient way of addressing classification problem on facial palsy type and degree of severity. Combining iris segmentation and key point-based method has several merits that are essential for our real application. Aside from the facial key points, iris segmentation provides significant contribution as it describes the changes of the iris exposure while performing some facial expressions. It reveals the significant difference between the healthy side and the severe palsy side when raising eyebrows with both eyes directed upward, and can model the typical changes in the iris region.

Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility. Sarcoidosis should therefore be an important consideration for the otolaryngologist's differential diagnosis of true vocal fold immobility. Copyright © 2018 The Voice Foundation.

A 77-year-old female with bilateral vocal cord paralysis and dependent tracheostomy status after total thyroidectomy presented to clinic for evaluation of decannulation via arytenoidectomy. Preliminary data suggests coblation versus standard CO2 laser ablation in arytenoidectomy may provide benefits in terms of decreased tissue necrosis and patient outcome. The patient elected to proceed with arytenoidectomy by coblation. The initial procedure went well but postoperative bleeding required a return trip to the operating room for hemostasis. In the coming months the patient's tracheostomy tube was gradually downsized and eventually capped. She was decannulated eight months after surgery, speaking well and without complaints. Details of the surgical procedure and outcome will be discussed. PMID:26457217

We report a case of a 19-year-old girl who presented with 5-year history of swelling of upper lip and fissured tongue treated with dapsone then oral steroids without any improvement. Clinical examination found peripheral facial nerve paralysis and Labial mucosa biopsy showed non-necrotizing giganto-epithelioid granuloma. Diagnosis of Melkersson-Rosenthal syndrome was retaind because of association of cheilitis, lingua plicata and facial paralysis. Given the failure of dapsone and oral steroid we suggested an association of betamethasone injection and doxycycline. Gradual and permanent reduction of the upper lip volume was observed. One year follow up objectified no reactivation of cheilitis. PMID:23397029

Evidence-based practice: evaluation and management of unilateral vocal fold paralysis.

Misono, Stephanie; Merati, Albert L

This article discusses the causes and symptoms, evaluation, and management of unilateral vocal fold paralysis (UVFP). Cross-sectional imaging is appropriate in the work-up of idiopathic UVFP, but the routine use of serology is not well supported. The usefulness of laryngeal electromyography has remained controversial. Predictors of poor prognosis for functionally meaningful recovery include fibrillation potentials, positive sharp waves, and absent/reduced voluntary motor unit potentials. Voice therapy may be helpful. Injection and laryngeal framework surgery (medialization thyroplasty) improve vocal quality. The vocal impact of laryngeal reinnervation is comparable with that of medialization. Some patients may benefit from multiple procedures. Copyright © 2012 Elsevier Inc. All rights reserved.

Paralysis recovery in humans and model systems

Considerable evidence now demonstrates that extensive functional and anatomical reorganization following spinal cord injury occurs in centers of the brain that have some input into spinal motor pools. This is very encouraging, given the accumulating evidence that new connections formed across spinal lesions may not be initially functionally useful. The second area of advancement in the field of paralysis recovery is in the development of effective interventions to counter axonal growth inhibition. A third area of significant progress is the development of robotic devices to quantify the performance level of motor tasks following spinal cord injury and to 'teach' the spinal cord to step and stand. Advances are being made with robotic devices for mice, rats and humans.

Ascending paralysis associated with HIV infection

We present two patients with a high viral load of HIV-1 who developed symptoms of ascending paralysis leading to respiratory failure and autonomic instability. One patient had symptom improvement with highly active antiretroviral therapy (HAART) and a subsequent decrease in viral load. The other patient improved with intravenous immunoglobulin therapy and did not show much improvement on HAART alone. There are several proposed mechanisms for peripheral neuropathies seen in HIV-infected patients, including a direct action of HIV on the nerve by neurotropic strains or formation of autoantibodies against nerve elements. The comparison of the response to different therapies in these two cases highlights the importance of understanding different pathophysiologies, as the treatment modality may differ. PMID:25552790

Ramsay Hunt syndrome (RHS) is a disorder characterized by herpetic eruptions on the auricle, facial paralysis, and vestibulocochlear dysfunction and is attributed to varicella zoster virus (VZV) infection in the geniculate ganglion. Although it is a common cause of acute peripheral facial paralysis, children are not usually affected. The diagnosis is based on history and physical findings. Treatment of RHS uses a combination of high-dose corticosteroids and acyclovir. This paper presents three cases diagnosed as RHS in the pediatric age group in association with the literature review. The aim of this paper is to emphasize the importance of careful examination and early initiation of therapy in suspected cases of RHS. PMID:26435868

A retrospective study to identify VAPP cases from the entire Uganda was conducted between January 2003 and December 2011. Eleven of the 106 AFP cases were VAPPs. The VAPP rate ranged from 0 to 3.39 cases per 1,000,000 birth cohorts and the peak was in 2009 when there was scaling up of OPV immunization activities following an importation of wild poliovirus in the country. All the subsequent polio suspect cases since then have been vaccine-associated polio cases. Our data support the strategy to withdraw OPV and introduce IPV progressively in order to mitigate against the paralysis arising from Sabin polioviruses. © 2015 Wiley Periodicals, Inc.

Israel acute paralysis virus (IAPV) is associated with colony collapse disorder of honey bees. Nonetheless, its role in the pathogenesis of the disorder and its geographic distribution are unclear. Here, we report phylogenetic analysis of IAPV obtained from bees in the United States, Canada, Australia, and Israel and the establishment of diagnostic real-time PCR assays for IAPV detection. Our data indicate the existence of at least three distinct IAPV lineages, two of them circulating in the United States. Analysis of representatives from each proposed lineage suggested the possibility of recombination events and revealed differences in coding sequences that may have implications for virulence.

Independent Component Analysis (ICA) is a powerful statistical tool capable of separating multivariate scalp electrical signals into their additive independent or source components, specifically EEG or electroencephalogram and artifacts. Although ICA is a widely accepted EEG signal processing technique, classification of the recovered independent components (ICs) is still flawed, as current practice still requires subjective human decisions. Here we build on the results from Fitzgibbon et al. [1] to compare three measures and three ICA algorithms. Using EEG data acquired during neuromuscular paralysis, we tested the ability of the measures (spectral slope, peripherality and spatial smoothness) and algorithms (FastICA, Infomax and JADE) to identify components containing EMG. Spatial smoothness showed differentiation between paralysis and pre-paralysis ICs comparable to spectral slope, whereas peripherality showed less differentiation. A combination of the measures showed better differentiation than any measure alone. Furthermore, FastICA provided the best discrimination between muscle-free and muscle-contaminated recordings in the shortest time, suggesting it may be the most suited to EEG applications of the considered algorithms. Spatial smoothness results suggest that a significant number of ICs are mixed, i.e. contain signals from more than one biological source, and so the development of an ICA algorithm that is optimised to produce ICs that are easily classifiable is warranted.

Muscle Channelopathies: the Nondystrophic Myotonias and Periodic Paralyses

PubMed Central

Statland, Jeffrey M.; Barohn, Richard J.

2013-01-01

Purpose of Review The muscle channelopathies are a group of rare inherited diseases caused by mutations in muscle ion channels. Mutations cause an increase or decrease in muscle membrane excitability, leading to a spectrum of related clinical disorders: the nondystrophic myotonias are characterized by delayed relaxation after muscle contraction, causing muscle stiffness and pain; the periodic paralyses are characterized by episodes of flaccid muscle paralysis. This review describes the clinical characteristics, molecular pathogenesis, and treatments of the nondystrophic myotonias and periodic paralyses. Recent Findings Advances have been made in both the treatment and our understanding of the molecular pathophysiology of muscle channelopathies: (1) a recent controlled trial showed that mexiletine was effective for reducing symptoms and signs of myotonia in nondystrophic myotonia; (2) the mechanisms by which hypokalemic periodic paralysis leads to a depolarized but unexcitable sarcolemma membrane have been traced to a novel gating pore current; and (3) an association was demonstrated between mutations in a potassium inward rectifier and patients with thyrotoxic periodic paralysis. Summary The muscle channelopathies are an expanding group of muscle diseases caused by mutations in sodium, chloride, potassium, and calcium ion channels that result in increased or decreased muscle membrane excitability. Recognizing patients with channelopathies and confirming the diagnosis is important, as treatment and management strategies differ based on mutation and clinical phenotype. PMID:24305449

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.

Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism characterized by episodes of weakness. Although TPP has been described in patients all over the world, it is especially frequent in Asiatic patients. Recently, two genomewide association studies have found a susceptibility locus on chromosome 17q24.3 near the KCNJ2 gene, which is responsible for another cause of periodic paralysis, the Andersen-Tawil syndrome (ATS). We report the first patient diagnosed with ATS with a de novo c.G899C mutation in the KCNJ2 gene in 2010 who developed an autoimmune hyperthyroidism and TPP in 2013. At the time of the ATS diagnosis other causes of periodic paralysis, including thyroid dysfunction, were ruled out. The condition of the patient, who had mild episodes of proximal weakness at follow-up, deteriorated dramatically in 2013, presenting continuous episodes of severe generalized weakness associated with low levels of potassium requiring frequent admissions to the hospital. After a few months, he also presented signs of hyperthyroidism, and a diagnosis of Grave's disease was made. In our opinion, this case clearly demonstrates that a dysfunction of the Kir2.1 potassium channel encoded by the KCNJ2 gene is a risk factor to develop TPP, and can be a useful tool to identify patients at risk in daily clinics.

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.

To explore the regulatory mechanisms of parasitism of Sclerodermus sichuanensis on Tenebrio molitor, the methods of natural parasitism and venom injection were adopted to investigate the effects of the venom from S. sichuanensis on the pupa of T. molitor in the parasitic process. Under venom injection, the paralytic degree of the pupa had a positive correlation with the concentration of injected venom, and the number of recovered pupa had a negative correlation with the injected venom concentration. The T. molitor pupa was in slight and reversible paralysis when injected with 0.01 VRE (venom reservoir equivalent) of venom, and in non-reversible and complete paralysis when 0.2 VRE was injected. The pupa died massively and appeared a wide range of melanization when injected with soil bacterial suspension alone, but the melanization delayed and the mortality declined significantly when the mixed liquor of bacterium and venom was injected. The bacteriostasis of the venom on Staphylococcus aureus was significantly stronger than that on Escherichia coli. Within a definite range of temperature, the paralytic activity decreased significantly with increasing temperature, the bacteriostasis on S. aureus increased significantly, while that on E. coli was opposite. This study showed that the venom from S. sichuanensis had the effects of paralysis, bacteriostasis, inhibiting exuviations, and delaying melanization.

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.

Objectives Evaluate the effects of asymmetric superior laryngeal nerve stimulation on the vibratory phase, laryngeal posture, and acoustics. Study Design Basic science study using an in vivo canine model. Methods The superior laryngeal nerves were symmetrically and asymmetrically stimulated over eight activation levels to mimic laryngeal asymmetries representing various levels of superior laryngeal nerve paresis and paralysis conditions. Glottal posture change, vocal fold speed, and vibration of these 64 distinct laryngeal activation conditions were evaluated by high speed video and concurrent acoustic and aerodynamic recordings. Assessments were made at phonation onset. Results Vibratory phase was symmetric in all symmetric activation conditions but consistent phase asymmetry towards the vocal fold with higher superior laryngeal nerve activation was observed. Superior laryngeal nerve paresis and paralysis conditions had reduced vocal fold strain and fundamental frequency. Superior laryngeal nerve activation increased vocal fold closure speed, but this effect was more pronounced for the ipsilateral vocal fold. Increasing asymmetry led to aperiodic and chaotic vibration. Conclusions This study directly links vocal fold tension asymmetry with vibratory phase asymmetry; in particular the side with greater tension leads in the opening phase. The clinical observations of vocal fold lag, reduced vocal range, and aperiodic voice in superior laryngeal paresis and paralysis is also supported. PMID:23712542

Despite more than a century of research, spinal paralysis remains untreatable via biological means. A new understanding of spinal cord physiology and the introduction of membrane fusogens have provided new hope that a biological cure may soon become available. However, proof is needed from adequately powered animal studies. Two groups of rats (n=9, study group, n=6 controls) were submitted to complete transection of the dorsal cord at T10. The animals were randomized to receive either saline or polyethylene glycol (PEG) in situ. After 4 weeks, the treated group had recovered ambulation vs none in the control group (BBB scores; P=.0145). One control died. All animals were studied with somatosensory-evoked potentials (SSEP) and diffusion tensor imaging (DTI). SSEP recovered postoperatively only in PEG-treated rats. At study end, DTI showed disappearance of the transection gap in the treated animals vs an enduring gap in controls (fractional anisotropy/FA at level: P=.0008). We show for the first time in an adequately powered study that the paralysis attendant to a complete transection of the spinal cord can be reversed. This opens the path to a severance-reapposition cure of spinal paralysis, in which the injured segment is excised and the two stumps approximated after vertebrectomy/diskectomies. © 2017 John Wiley & Sons Ltd.

The authors are presenting a series of 10 cases of complete unilateral facial paralysis submitted to (I) end-to-end microsurgical coaptation of the masseteric branch of the trigeminal nerve and distal branches of the paralyzed facial nerve, and (II) cross-face sural nerve graft. The ages of the patients ranged from 5 to 63 years (mean: 44.1 years), and 8 (80%) of the patients were females. The duration of paralysis was no longer than 18 months (mean: 9.7 months). Follow-up varied from 6 to 18 months (mean: 12.6 months). Initial voluntary facial movements were observed between 3 and 6 months postoperatively (mean: 4.3 months). All patients were able to produce the appearance of a smile when asked to clench their teeth. Comparing the definition of the nasolabial fold and the degree of movement of the modiolus on both sides of the face, the voluntary smile was considered symmetrical in 8 cases. Recovery of the capacity to blink spontaneously was not observed. However, 8 patients were able to reduce or suspend the application of artificial tears. The authors suggest consideration of masseteric-facial nerve coaptation, whether temporary (baby-sitter) or permanent, as the principal alternative for reconstruction of facial paralysis due to irreversible nerve lesion with less than 18 months of duration.

Exploding head syndrome is common in college students.

Exploding head syndrome is characterized by the perception of loud noises during sleep-wake or wake-sleep transitions. Although episodes by themselves are relatively harmless, it is a frightening phenomenon that may result in clinical consequences. At present there are little systematic data on exploding head syndrome, and prevalence rates are unknown. It has been hypothesized to be rare and to occur primarily in older (i.e. 50+ years) individuals, females, and those suffering from isolated sleep paralysis. In order to test these hypotheses, 211 undergraduate students were assessed for both exploding head syndrome and isolated sleep paralysis using semi-structured diagnostic interviews: 18.00% of the sample experienced lifetime exploding head syndrome, this reduced to 16.60% for recurrent cases. Though not more common in females, it was found in 36.89% of those diagnosed with isolated sleep paralysis. Exploding head syndrome episodes were accompanied by clinically significant levels of fear, and a minority (2.80%) experienced it to such a degree that it was associated with clinically significant distress and/or impairment. Contrary to some earlier theorizing, exploding head syndrome was found to be a relatively common experience in younger individuals. Given the potential clinical impacts, it is recommended that it be assessed more regularly in research and clinical settings. © 2015 European Sleep Research Society.

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.

CRYSTAL STRUCTURE OF CLOSTRIDIUM BOTULINUM NEUROTOXIN SEROTYPE B.

The toxigenic strains of Clostridium botulinum produce seven serologically distinct types of neurotoxins labeled A - G (EC 3.4.24.69), while Clostridium tetani produces tetanus neurotoxin (EC 3.4.24.68). Botulinum and tetanus neurotoxins (BoNTs and TeNT) are produced as single inactive chains of molecular mass of approximately 150 kDa. Most of these neurotoxins are released after being cleaved into two chains, a heavy chain (HI) of 100 kDa and a light chain (L) of 50 kDa held together by an interchain disulfide bond, by tissue proteinases. BoNT/E is released as a single chain but cleaved by host proteinases [1]. Clostvidium botulinum neurotoxinsmore » are extremely poisonous proteins with their LD{sub 50} for humans in the range of 0.1 - 1 ng kg{sup -1} [2]. Botulinum neurotoxins are responsible for neuroparalytic syndromes of botulism characterized by serious neurological disorders and flaccid paralysis. BoNTs block the release of acetylcholine at the neuromuscular junction causing flaccid paralysis while TeNT blocks the release of neurotransmitters like glycine and {gamma}-aminobutyric acid (GABA) in the inhibitory interneurons of the spinal cord resulting in spastic paralysis. In spite of different clinical symptoms, their aetiological agents intoxicate neuronal cells in the same way and these toxins have similar structural organization [3].« less

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.

In a previous study of patients with unilateral vocal-fold paralysis (UVFP), three-dimensional computed tomography (3DCT) revealed passive movement during phonation, with the arytenoid cartilage on the paralyzed side pushed to the unaffected side and deviated upwards. The present work compares the 3DCT findings with those obtained by 2-dimensional endoscopy to visualize the vertical passive movement of the arytenoid cartilage. The study population consisted of 23 patients with UVFP and two with laryngeal deviation but normal movement of the vocal folds. Two endoscopic findings represented cranial deviation during phonation: posterior deviation of the arytenoid hump and lateral deviation of the muscular process. These two findings were classified into four grades, ranging from 0 (normal) to 3 (severe). Cranial displacement detected by 3DCT was also classified into four grades. Significant correlations were found between the 3DCT-determined grade of cranial displacement of the arytenoid cartilage and the grade assigned based on the two endoscopic findings. Moreover, lateral deviation of the muscular process was more significantly correlated with 3DCT grade than with endoscopic grade. Thus, endoscopic findings may be useful in the diagnosis of vocal-fold paralysis, and passive lateral deviation of the muscular process as an indicator of UVFP.

The classification of voice diseases has many applications in health, in diseases treatment, and in the design of new medical equipment for helping doctors in diagnosing pathologies related to the voice. This work uses the parameters of the glottal signal to help the identification of two types of voice disorders related to the pathologies of the vocal folds: nodule and unilateral paralysis. The parameters of the glottal signal are obtained through a known inverse filtering method, and they are used as inputs to an Artificial Neural Network, a Support Vector Machine, and also to a Hidden Markov Model, to obtain the classification, and to compare the results, of the voice signals into three different groups: speakers with nodule in the vocal folds; speakers with unilateral paralysis of the vocal folds; and speakers with normal voices, that is, without nodule or unilateral paralysis present in the vocal folds. The database is composed of 248 voice recordings (signals of vowels production) containing samples corresponding to the three groups mentioned. In this study, a larger database was used for the classification when compared with similar studies, and its classification rate is superior to other studies, reaching 97.2%.

Cardiac involvement as an initial presentation of malignant lymphoma is a rare occurrence. We describe the case of a 26 year old man who had initially been diagnosed with myocardial infiltration on an echocardiogram, presenting with a testicular mass and unilateral peripheral facial paralysis. On admission, electrocardiograms (ECG) revealed negative T-waves in all leads and ST-segment elevation in the inferior leads. On two-dimensional echocardiography, there was infiltration of the pericardium with mild effusion, infiltrative thickening of the aortic walls, both atria and the interatrial septum and a mildly depressed systolic function of both ventricles. An axillary biopsy was performed and reported as a T-cell lymphoblastic lymphoma (T-LBL). Following the diagnosis and staging, chemotherapy was started. Twenty-two days after finishing the first cycle of chemotherapy, the ECG showed regression of T-wave changes in all leads and normalization of the ST-segment elevation in the inferior leads. A follow-up Two-dimensional echocardiography confirmed regression of the myocardial infiltration. This case report illustrates a lymphoma presenting with testicular mass, unilateral peripheral facial paralysis and myocardial involvement, and demonstrates that regression of infiltration can be achieved by intensive chemotherapy treatment. To our knowledge, there are no reported cases of T-LBL presenting as a testicular mass and unilateral peripheral facial paralysis, with complete regression of myocardial involvement.

OBJECTIVE: Vaccine-associated paralytic poliomyelitis (VAPP) is a rare but serious consequence of the administration of oral polio vaccine (OPV). Intensified OPV administration has reduced wild poliovirus transmission in India but VAPP is becoming a matter of concern. METHODS: We analysed acute flaccid paralysis (AFP) surveillance data in order to estimate the VAPP risk in this country. VAPP was defined as occurring in AFP cases with onset of paralysis in 1999, residual weakness 60 days after onset, and isolation of vaccine-related poliovirus. Recipient VAPP cases were a subset with onset of paralysis between 4 and 40 days after receipt of OPV. FINDINGS: A total of 181 AFP cases met the case definition. The following estimates of VAPP risk were made: overall risk, 1 case per 4.1 to 4.6 million OPV doses administered; recipient risk,1 case per 12.2 million; first-dose recipient risk, 1 case per 2.8 million; and subsequent-dose recipient risk, 1 case per 13.9 million. CONCLUSION: On the basis of data from a highly sensitive surveillance system the estimated VAPP risk in India is evidently lower than that in other countries, notwithstanding the administration of multiple OPV doses to children in mass immunization campaigns.

Analysis of epidemiology of 4 clustered high risk acute flaccid paralysis(AFP) cases reported by Shanxi province in 2006 and VP1 gene characteristic for type III poliovirus isolated from the four AFP cases. Virus isolation and identification were conducted according to the 4th edition of WHO polio laboratory manual. The sequence of VP1 region were amplified and sequenced. The phylogenetic trees based on VP1 region were constructed. Three of four high risk AFP cases were suspected as vaccine associated paralysis poliomyelitis (VAPP), the onset date of them were close. VP1 sequencing of the four type III isolates revealed that the identity were 99.7%, 99.9%, 99.4% and 99.9% respectively compared with vaccine reference strain-BJOPV3. According to WHO criteria, the four isolates were identified as type III vaccine-related poliovirus. Phylogenetic analysis based on VP1 coding sequence showed that the four type III poliovirus were not related significantly. The type III poliovirus isolated from 3 suspected VAPP cases shared one nucleotide mutation at 2637 (C-->U), which result in the amino acid mutation from Val into Ala. The improvement of laboratory surveillance for clustered high risk AFP cases should be strengthened so as to detect and prevent poliovirus circulation timely.

Motor exam of patients with spinal cord injury: a terminological imbroglio.

PubMed

Figueiredo, Nicandro

2017-07-01

The description of the motor deficit of patients with spinal cord injury (SCI) varies significantly, leading to confusion within the neurological terminology. This paper proposes a concise and easy to use terminology to describe the motor deficit of patients with SCI. A broad review of the origin of the nomenclature used to describe the motor deficit of patients with SCI was performed and discussed. The prefix: "hemi" should be used to describe paralysis of one half of the body; "mono" for one limb; "para" for lower limbs, di" for two symmetrical segments and/or parts in both sides of the body; "tri" for three limbs, or two limbs and one side of the face; and "tetra" for four limbs. The suffix: "plegia" should be used for total paralysis of a limb or part of the body, and "paresis" for partial paralysis. The term "brachial" refers to the upper limbs; and "podal" to the lower limbs. According to the spinal cord origin of the main key muscles for the limbs, patients with complete injury affecting spinal cord segments C1-5 usually presents with "tetraplegia"; C6-T1 presents with "paraplegia and brachial diparesis"; T2-L2 with "paraplegia"; and L3-S1 with "paraparesis".

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.

The aim of this prospective study is to investigate whether the possible stenosis due to anatomic variations of labyrinthine segment (LS), tympanic segment (TS) and mastoid segment (MS) of the facial canal in the temporal bone is a predisposing factor in the development of paralysis. 22 patients with idiopathic peripheral facial paralysis (IPFP) were included in the study. Multi-slice computed tomography (MSCT) with 64 detectors was used for temporal bone imaging of the patients. Reconstruction images in axial, coronal and sagittal planes were created in workstation computers from the captured images. The diameters and lengths of LS, TS and MS of the facial canal were measured. The mean values of LD, ND and SL of LS were 1.31 ± 0.39, 0.91 ± 0.27, 4.17 ± 0.48 in patient group and 1.26 ± 0.29, 0.95 ± 0.21, 4.60 ± 1.36 in control group, respectively. The mean values of LD, ND and SL of TS were 1.11 ± 0.22, 0.90 ± 0.14, 12.63 ± 1.47 in patient group and 1.17 ± 0.23, 0.85 ± 0.24, 12.10 ± 1.79 in control group, respectively. The mean values of LD, ND and SL of MS were 1.80 ± 0.30, 1.44 ± 0.29 vs. 14.3 ± 1.90 in patient group 1.74 ± 0.38, 1.40 ± 0.29, 14.15 ± 2.16 in control group, respectively. The measurements of the parameters of all three segments in patient group and control group were similar. Similar results between patient and control group were obtained in this study investigating the effect of stenosis in facial canal in the development of IPFP.

Introduction: According to the high incidence of Bell's palsy (IFP) and lack of clinical data regarding different aspects of disease, the present study investigated 121 Iranian patients with peripheral facial paralysis referred to the emergency department. Methods: In this retrospective study, all patients with peripheral facial paralysis, referred to the emergency department of Poursina hospital, Rasht, Iran, from August 2012 to August 2013, were enrolled. For all patients with diagnosis of Bell's palsy variables such as age, sex, occupation, clinical symptoms, comorbid disease, grade of paralysis, and the severity of the facial palsy were reviewed and analyzed using STATA version 11.0. Results: 121 patients with peripheral facial paralysis were assessed with a mean age of 47.14±18.45 years (52.9% male). The majority of patients were observed in the summer (37.2%) and autumn (33.1%) and the recurrence rate was 22.3%. The most common grades of nerve damage were IV and V based on House-Brackman grading scale (47.1%). Also, the most frequent signs and symptoms were ear pain (43.8%), taste disturbance (38.8%), hyperacusis (15.7%) and increased tearing (11.6%). There were not significant correlations between the severity of palsy with age (p= 0.08), recurrence rate (p=0.18), season (p=0.9), and comorbid disease including hypertension (p=0.18), diabetes (p=0.29), and hyperlipidemia (p=0.94). The patients with any of following symptoms such as ear pain (p<0.001), taste disturbance (p<0.001), increased tearing (p=0.03), and Hyperacusis (p<0.001) have more severe palsy. Conclusion: There was equal gender and occupational distribution, higher incidence in fourth decade of life, higher incidence in summer and autumn, higher grade of nerve damage (grade V and VI), and higher incidence of ear pain and taste disturbance in patients suffered from IFP. In addition, there was significant association between severity of nerve damage and presence of any simultaneous symptoms. PMID:26495349

In recent years, on the one hand, the mortality rates of upper cervical spine injuries, such as odontoid fractures, were suggested to be not so high, but on the other hand reported to be significantly high. Furthermore, it has not been well documented the relationship between survival rates and various clinical features in those patients during the acute phase of injury because of few reports. This study aimed to evaluate survival rates and acute-phase clinical features of upper cervical spine injuries. We conducted a retrospective review of all patients who were transported to the advanced emergency medical center and underwent computed tomography of the cervical spine at our hospital between January 2006 and December 2015. We excluded the patients who were discovered in a state of cardiopulmonary arrest (CPA) and could not be resuscitated after transportation. Of the 215 consecutive patients with cervical spine injuries, we examined 40 patients (18.6%) diagnosed with upper cervical spine injury (males, 28; females, 12; median age, 58.5 years). Age, sex, mechanism of injury, degree of paralysis, the level of cervical injury, injury severity score (ISS), and incidence of CPA at discovery were evaluated and compared among patients classified into the survival and mortality groups. The survival rate was 77.5% (31/40 patients). In addition, complete paralysis was observed in 32.5% of patients. The median of ISS was 34.0 points, and 14 patients (35.0%) presented with CPA at discovery. Age, the proportion of patients with complete paralysis, a high ISS, and incidence of CPA at discovery were significantly higher in the mortality group (p = 0.038, p = 0.038, p < 0.001, and p < 0.001, respectively). Elderly people were more likely to experience upper cervical spine injuries, and their mortality rate was significantly higher than that in injured younger people. In addition, complete paralysis, high ISS, a state of CPA at discovery, was significantly higher in the mortality group.

Remapping cortical modulation for electrocorticographic brain-computer interfaces: a somatotopy-based approach in individuals with upper-limb paralysis

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 realm.

To evaluate the effectiveness of the median nerve constrictive operation combined with tendon transfer to treat the brain paralysis convulsive deformity of the hand. The clinical data from 21 cases with brain paralysis convulsive deformity of the hand were analyzed retrospectively between August 2009 and April 2012. Of them, there were 13 males and 8 females with an average age of 15 years (range, 10-29 years). The causes of the convulsive cerebral palsy included preterm deliveries in 11 cases, hypoxia asphyxia in 7, traumatic brain injury in 2, and encephalitis sequela in 1. The disease duration was 2-26 years (mean, 10.6 years). All the 21 patients had cock waists, crooking fingers, and contracture of adductors pollicis, 12 had the forearm pronation deformity. According to Ashworth criteria, there were 2 cases at level I, 5 cases at level II, 8 cases at level III, 4 cases at level IV, and 2 cases at level V. All patients had no intelligence disturbances. The forearm X-ray film showed no bone architectural changes before operation. The contraction of muscle and innervation was analyzed before operation. The median nerve constrictive operation combined with tendon transfer was performed. The functional activities and deformity improvement were evaluated during follow-up.

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 paralysis. One study reported a significant difference between the treatment groups in favour of the aciclovir plus corticosteroid group over corticosteroid alone, another demonstrated an inconclusive result with no difference between the aciclovir and corticosteroid. The third study did not comment upon these sequelae. More data are needed from a large multicentre randomised controlled and blinded study with at least 12 months' follow up before a definitive recommendation can be made regarding the effect of aciclovir or valaciclovir on Bell's palsy. Two trials, one with 551 participants comparing prednisolone with acyclovir with both and with neither, another with 221 participants comparing prednisolone and valacyclovir with prednisolone and placebo have just been published and will be included in an update of this review.

The tuberculosis of the ear is rare, and in most cases the clinical picture resembles that of a chronic otitis media. The diagnosis is often delayed, and this can lead to irreversible complications such as hearing loss and/or facial paralysis. In view of its rare occurrence, we report a case of primary tuberculous otitis media in a 87-year-old female patient. The diagnosis was made on the basis of both histological and microbiological findings. In particular, gene amplification techniques such as real-time polymerase chain reaction are useful method for rapid diagnosis and detecting tuberculous bacilli usually present at very low number. Early diagnosis is essential for the prompt institution of antituberculous therapy.

Williams-Beuren syndrome is a rare neurodevelopmental disorder caused by deletion of 1.5-1.8Mb genes on chromosome 7q11.23. The syndrome was first described as a triad of supra-valvular aortic stenosis, mental retardation, and distinctive facial features. Our patient was referred due to audible inspiratory stridor when he was seven days old. Following endoscopy he was diagnosed with bilateral vocal cord paralysis and was eventually intubated due to respiratory de-compensation followed by tracheotomy. On further workup he was diagnosed with hypothyroidism. Genetic workup supported the diagnosis of Williams-Beuren syndrome. We report here a case with an unusual clinical presentation.

Restoration of facial symmetry in a patient with bell palsy using a modified maxillary complete denture: a case report.

PubMed

Bagchi, Gautam; Nath, Dilip Kumar

2012-01-01

Permanent facial paralysis can be devastating for a patient. Modern society's emphasis on appearance and physical beauty contributes to this problem and often leads to isolation of patients embarrassed by their appearance. Lagophthalmos with ocular exposure, loss of oral competence with resultant drooling, alar collapse with nasal airway obstruction, and difficulties with mastication and speech production are all potential consequences of facial paralysis. Affected patients are confronted with both a cosmetic defect and the functional deficits associated with loss of facial nerve function. In this case history report, a modified maxillary complete denture permitted a patient with Bell palsy to carry on daily activities with minimal facial distortion, pain, speech difficulty, and associated emotional trauma.

Bell’s palsy: data from a study of 70 cases

PubMed Central

Cirpaciu, D; Goanta, CM

2014-01-01

Bell’s palsy is a condition that affects the facial nerve, which is one of the twelve cranial nerves. Its main function is to control all the muscles of the facial expression. It is a unilateral, acute, partial or complete paralysis of the facial nerve. Bell's palsy remains the most common cause of facial nerve paralysis, more often encountered in females aged 17 to 30 years, recurrent in many cases and with poor associations with other pathologic conditions. In modern literature, the suspected etiology could be due to the reactivation of the latent herpes viral infections in the geniculate ganglia, and their subsequent migration to the facial nerve but, favorable outcome by using vasodilators, neurotrophic and corticosteroid therapy was recorded.

Paralysis is considered as a major curse in this world. The number of persons who are paralyzed and therefore dependent on others due to loss of self-mobility is growing with the population. Quadriplegia is a form of Paralysis in which you can only move your eyes. Much work has been done to help disabled persons to live independently. Various methods are used for the same and this paper enlists some of the already existing methods along with some add-ons to improve the existing system. Add-ons include a system, which will be designed using Raspberry Pi and IR Camera Module. OpenCV will be used for image processing and Python is used for programming the Raspberry Pi.

The fate of lyophilized (methylmethacrylate-14C, 2-hydroxyethylmethacrylate, butylacrylate) nanoparticles was studied in male Wistar rats after p.o. administration. It was found that at least 4% of the dose of 14C was absorbed from the gastrointestinal tract after a single dose with these nanoparticles. Some radioactivity (less than 0.15% of dose) was found 7 d after administration in lung, spleen and liver. As expected excretion of the label was predominated via the feces. Ten d of p.o. treatment of rats with lyophilized nanoparticles (1 g/kg of body weight) was shown to prolong significantly zoxazolamine paralysis time. This result suggests that lyophilized nanoparticles decreased elimination of zoxazolamine.

We report on a family with a not earlier described multiple congenital malformation. Several male family members suffer from laryngeal obstruction caused by bilateral vocal cord paralysis, outer and middle ear deformity with conductive and sensorineural hearing loss, facial dysmorphisms, and underdeveloped shoulder musculature. The affected female members only have middle ear deformity and hearing loss. The pedigree is suggestive of an X-linked recessive inheritance pattern. SNP-array revealed a deletion and duplication on Xq28 in the affected family members. A possible aetiology is a neurocristopathy with most symptoms expressed in structures derived from branchial arches. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

It has become common to use scales to measure the degree of involvement of facial paralysis in phonoaudiological clinics. To analyze the inter- and intra-rater agreement of the scales of degree of facial paralysis and to elicit point of view of the appraisers regarding their use. Cross-sectional observational clinical study of the Chevalier and House & Brackmann scales performed by five speech therapists with clinical experience, who analyzed the facial expression of 30 adult subjects with impaired facial movements two times, with a one week interval between evaluations. The kappa analysis was employed. There was excellent inter-rater agreement for both scales (kappa>0.80), and on the Chevalier scale a substantial intra-rater agreement in the first assessment (kappa=0.792) and an excellent agreement in the second assessment (kappa=0.928). The House & Brackmann scale showed excellent agreement at both assessments (kappa=0.850 and 0.857). As for the appraisers' point of view, one appraiser thought prior training is necessary for the Chevalier scale and, four appraisers felt that training is important for the House & Brackmann scale. Both scales have good inter- and intra-rater agreement and most of the appraisers agree on the ease and relevance of the application of these scales.

Cohen-Lehman, Janna; Charitou, Marina M; Klein, Irwin

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.

Unilateral vocal fold paralysis in premature infants after ligation of patent ductus arteriosus: vascular clip versus suture ligature.

We investigated risk factors associated with unilateral iatrogenic vocal fold paralysis (IVFP) in the context of ligation of patent ductus arteriosus (PDA) and compared the rates of paralysis between vascular clip and suture ligation procedures. We performed a prospective examination of infants with isolated PDA treated surgically during 1995 to 2005. Statistical significance was determined with a 2-tailed t-test. Of 68 PDA ligations, 13 cases of left-sided IVFP were diagnosed, for an overall incidence of 19%. All cases of IVFP occurred in 55 infants who weighed less than 1 kg at birth. Suture ligature was used in 60% of all PDA ligation patients, and vascular clips in 40%. The incidence of IVFP in patients with vascular clips (19%) was similar to the incidence in those with suture ligature (20%). Hoarseness or stridor was present in 69% of patients with IVFP, compared to 17% of normal controls (p <0.001). The rate of aspiration was not increased in the IVFP group; however, 15% of the patients with IVFP had episodes of decreased oxygen saturation, versus 7% of infants with normal vocal fold mobility. A hoarse infant with a birth weight of less than 1 kg who has undergone PDA ligation should be examined for unilateral IVFP. Vascular clips and suture ligature are associated with similar rates of IVFP.

A sequential anesthesia technique for surgical repair of unilateral vocal fold paralysis.

Thyroplasty with arytenoid adduction, a combined procedure for treatment of unilateral vocal fold paralysis, is typically performed under local anesthesia with sedation to allow for intraoperative voice assessment. However, the need for patient immobility and suppression of laryngeal responses to surgical manipulation can make sedation-analgesia challenging. We describe our first 26 consecutive cases undergoing thyroplasty and arytenoid adduction with a standardized technique consisting of a combination of general anesthesia with tracheal intubation followed by sedation-analgesia. Most patients (69 %) were women, with age of 53 ± 15 years (mean ± SD). Neck surgery was the cause of vocal fold paralysis in 50 % of patients. Initially, general anesthesia was maintained with desflurane and remifentanil with dexmedetomidine added just before tracheal extubation. During the sedation-analgesia phase, patients received infusions of remifentanil and dexmedetomidine. Duration of general anesthesia and sedation-analgesia phases was 162 ± 68.2 and 79 ± 18.3 min, respectively. Mean (SD) wake-up time was 8.0 ± 4.0 min after desflurane discontinuation. Extubation occurred without coughing, bucking, or agitation in 96 % of patients. All the patients were able to phonate appropriately and remained comfortable after emergence. This technique allowed improved surgical conditions with reduced patient discomfort and may be advantageous for other laryngeal and neck surgeries in which intraoperative patient feedback is required.

In vitro screening for cestocidal activity of three species of Cassia plants against the tapeworm Raillietina tetragona.

Different species of Cassia plant are widely available in India and are commonly used either for their laxative, antimicrobial or antibacterial activity. In the present study the effectiveness in vitro of the crude alcoholic extracts of three species, namely Cassia alata, C. occidentalis and C. angustifolia, in the early paralysis and mortality of the fowl tapeworm Raillietina tetragona at concentrations ranging from 5 to 80 mg/ml was investigated. Time of paralysis and death were monitored frequently. Immediately after paralysis the tapeworms were processed for electron microscopic studies. While the untreated or control parasites survived for 81.93 ± 5.85 h, the parasites treated with C. alata took less time (1.68 ± 0.27 h) to be paralysed, followed by those treated with C. angustifolia (2.95 ± 0.29 h). Although C. occidentalis took more time (4.13 ± 0.31 h) to paralyse, in combination with either C. alata or C. angustifolia the time taken to paralyse became shorter. All the plant-treated parasites showed irrevocable changes in the scolex and proglottids as compared with the control, and these observations are comparable with those obtained with praziquantel. These results indicate that the three plants tested can be claimed to have anthelmintic activity in addition to their known properties, both when used individually and in combination. Further investigations will be required to evaluate their mechanism of action.

Cardiac involvement as an initial presentation of malignant lymphoma is a rare occurrence. We describe the case of a 26 year old man who had initially been diagnosed with myocardial infiltration on an echocardiogram, presenting with a testicular mass and unilateral peripheral facial paralysis. On admission, electrocardiograms (ECG) revealed negative T-waves in all leads and ST-segment elevation in the inferior leads. On two-dimensional echocardiography, there was infiltration of the pericardium with mild effusion, infiltrative thickening of the aortic walls, both atria and the interatrial septum and a mildly depressed systolic function of both ventricles. An axillary biopsy was performed and reported as a T-cell lymphoblastic lymphoma (T-LBL). Following the diagnosis and staging, chemotherapy was started. Twenty-two days after finishing the first cycle of chemotherapy, the ECG showed regression of T-wave changes in all leads and normalization of the ST-segment elevation in the inferior leads. A follow-up Two-dimensional echocardiography confirmed regression of the myocardial infiltration. This case report illustrates a lymphoma presenting with testicular mass, unilateral peripheral facial paralysis and myocardial involvement, and demonstrates that regression of infiltration can be achieved by intensive chemotherapy treatment. To our knowledge, there are no reported cases of T-LBL presenting as a testicular mass and unilateral peripheral facial paralysis, with complete regression of myocardial involvement. PMID:24109501

Orexin Gene Transfer into Zona Incerta Neurons Suppresses Muscle Paralysis in Narcoleptic Mice

Cataplexy, a sudden unexpected muscle paralysis, is a debilitating symptom of the neurodegenerative sleep disorder, narcolepsy. During these attacks, the person is paralyzed, but fully conscious and aware of their surroundings. To identify potential neurons that might serve as surrogate orexin neurons to suppress such attacks, the gene for orexin (hypocretin), a peptide lost in most human narcoleptics, was delivered into the brains of the orexin-ataxin-3 transgenic mouse model of human narcolepsy. Three weeks after the recombinant adenoassociated virus (rAAV)-mediated orexin gene transfer, sleep–wake behavior was assessed. rAAV-orexin gene delivery into neurons of the zona incerta (ZI), or the lateral hypothalamus (LH) blocked cataplexy. Orexin gene transfer into the striatum or in the melanin-concentrating hormone neurons in the ZI or LH had no such effect, indicating site specificity. In transgenic mice lacking orexin neurons but given rAAV-orexin, detectable levels of orexin-A were evident in the CSF, indicating release of the peptide from the surrogate neurons. Retrograde tracer studies showed that the amygdala innervates the ZI consistent with evidence that strong emotions trigger cataplexy. In turn, the ZI projects to the locus ceruleus, indicating that the ZI is part of a circuit that stabilizes motor tone. Our results indicate that these neurons might also be recruited to block the muscle paralysis in narcolepsy. PMID:21508228

Enteroviruses, members of the Picornaviridae family, are ubiquitous viruses responsible for mild to severe infections in human populations around the world. In 2010 Pointe-Noire, Republic of Congo recorded an outbreak of acute flaccid paralysis (AFP) in the humans, caused by wild poliovirus type 1 (WPV1). One month later, in the Tchimpounga sanctuary near Pointe-Noire, a chimpanzee developed signs similar to AFP, with paralysis of the lower limbs. In the present work, we sought to identify the pathogen, including viral and bacterial agents, responsible for this illness. In order to identify the causative agent, we evaluated a fecal specimen by PCR and sequencing. A Human enterovirus C, specifically of the EV-C99 type was potentially responsible for the illness in this chimpanzee. To rule out other possible causative agents, we also investigated the bacteriome and the virome using next generation sequencing. The majority of bacterial reads obtained belonged to commensal bacteria (95%), and the mammalian virus reads matched mainly with viruses of the Picornaviridae family (99%), in which enteroviruses were the most abundant (99.6%). This study thus reports the first identification of a chimpanzee presenting AFP most likely caused by an enterovirus and demonstrates once again the cross-species transmission of a human pathogen to an ape.

Melkersson Rosenthal syndrome is a very infrequent disease of unknown etiology, chronic and progressive course, with neurocutaneous disease that affects the orofacial innervation and mucocutaneous tissues with non-caseating granulomatous infiltration. Clinically, it is characterized by the diagnostic triad: recurrent edema of lips and/or face; recurrent and alternating acute peripheral facial paralysis and scrotal or geographic tongue. The condition generally presents as oligosymptomatic or monosymptomatic form. Two patients are presented with completed triad and oligosymptomatic form. This recent review published by G. Kayabasoglu et al. states that only 30 patients have been described in the international literature in childhood. So we consider this disease in the differential diagnosis in the presence of acute peripheral facial paralysis and/or lips or facial edema. Sociedad Argentina de Pediatría.

The Ramsay Hunt syndrome is a rare disease caused by an infection of the geniculate ganglion by the varicella-zoster virus. The main clinical features of the syndrome are as follows: Bell palsy unilateral or bilateral, vesicular eruptions on the ears, ear pain, dizziness, preauricular swelling, tingling, tearing, loss of taste sensation, and nystagmus. We describe a 23-year-old white woman, who presented with facial paralysis on the left side of the face, pain, fever, ear pain, and swelling in the neck and auricular region on the left side.

Professor HE Tianyou's unique understanding and treatment characteristics for intractahle facial paralysis are introduced. In clinical practice professor HE highly values acupoint selection and manipulation application, and integrates Chinese and western medicine to flexibly choose acupoints and formulate prescriptions according to syndrome differentiation and location differentiation, besides, he creates several specialized manipulation methods including "tug-of war opposite acupuncture method" and "tractive flash cupping". Based on strengthening body and dredging collaterals. more attention is given on stimulation to local paralyzed facial nerves; meanwhile acupuncture and medication are combined to improve clinical efficacy. During the treatment, the important role of psychological counseling on patient's anxiety is emphasized, and comprehensive treatment is given physically and psychologically in order to achieve the purpose of total rehabilitation.

In 1938, President Franklin D. Roosevelt and his law partner Basil O'Connor formed the National Foundation for Infantile Paralysis (NFIP) to battle the viral disease poliomyelitis. Although the NFIP program was purported to be available for all Americans irrespective of "race, creed, or color," officials encountered numerous difficulties upholding this pledge in a nation divided by race. In 1944, NFIP officials hired educator Charles H. Bynum to head a new department of "Negro Activities." Between 1944 and 1954, Bynum negotiated the NFIP bureaucracy to educate officials and influence their national health policy. As part of the NFIP team, he helped increase interracial fund-raising in the March of Dimes, improve polio treatment for black Americans, and further the civil rights movement.

'Shrouded in a dark fog': comparison of the diagnosis of pellagra in Venice and general paralysis of the insane in the United Kingdom, 1840-1900.

The debate on the causes and the nature of pellagra in Italy during the nineteenth century resembles and evokes the similar debate on General Paralysis of the Insane (GPI) that was growing at the same time in the United Kingdom. Pellagra and GPI had a massive and virulent impact on the populations of Italy and the UK, respectively, and contributed to a great extent to the increase and overcrowding of the asylum populations in these countries. This article compares the two illnesses by examining the features of their nosographic positioning, aetiology and pathogenesis. It also documents how doctors arrived at the diagnoses of the two diseases and how this affected their treatment.

Infection of hamsters with the murine flavivirus Modoc results in (meningo)encephalitis, which is, during the acute phase, frequently associated with flaccid paralysis, as also observed in patients with West Nile virus encephalitis. Twenty percent of the hamsters that recover from the acute encephalitis develop life-long neurological sequelae, reminiscent of those observed, for example, in survivors of Japanese encephalitis. Magnetic resonance imaging and histology revealed severe lesions predominantly located in the olfactory-limbic system, both in hamsters with acute encephalitis as in survivors. Prominent pathology was also detected in the spinal cord of hamsters with paralysis. Modoc virus infections in hamsters provide a unique model for the study of encephalitis, a poliomyelitis-like syndrome and neurological sequelae following flavivirus infection.

Guillian Barré syndrome--recent advances.

2000-09-01

Guillian Barré Syndrome (GBS) is an acquired disease of the peripheral nerves that is characterized clinically by rapidly progressing paralysis, areflexia, and albumino-cytological dissociation. It affects both genders, involves people of all ages, is reported worldwide, and in the post-polio era, it is the most common cause of an acute generalized paralysis. The clinical features are distinct and a history and an examination generally lead to a high suspicion of the diagnosis that can then be confirmed by supportive laboratory tests and electrodiagnostic studies. This review discusses the recent advances in understanding of the different variants of GBS such as acute inflammatory demyelinating polyneuropathy (AIDP), acute motor axonal neuropathy (AMAN), acute motor sensory axonal neuropathy (AMSAN), and the Fisher syndrome. The clinical, electrodiagnostic criteria, immunopathogenesis, and management of GBS and its variants are discussed.

Delineation of an endemic tick paralysis zone in southeastern Australia.

Tick paralysis has a major impact on pet dog and cat populations in southeastern Australia. It results from envenomation by Ixodes holocyclus and Ixodes cornuatus ticks, the role of Ixodes cornuatus in the epidemiology of this disease in Australia being unclear. The aim of this study was to describe the geographical distribution of tick paralysis cases in southeastern Australia using data from a national disease surveillance system and to compare characteristics of "endemic" cases with those reported outside this endemic zone ("sporadic" cases). Data were collated and a proportional symbol map of all cases by postcode was created. A 15-case isopleth was developed based on descriptive spatial statistics (directional ellipses) and then kernel smoothing to distinguish endemic from sporadic cases. During the study period (January 2010-December 2015) 12,421 cases were reported, and 10,839 of these reported by clinics located in 434 postcodes were included in the study. Endemic cases were predominantly reported from postcodes in coastal southeastern Australia, from southern Queensland to eastern Victoria. Of those cases meeting selection criteria, within the endemic zone 10,767 cases were reported from 351 (88%) postcodes and outside this zone 72 cases were reported from 48 (12%) postcodes. Of these latter 48 postcodes, 18 were in Victoria (26 cases), 16 in New South Wales (28 cases), 7 in Tasmania (9 cases), 5 in South Australia (7 cases) and 2 in Queensland (2 cases). Seasonal distribution in reporting was found: 62% of endemic and 52% of sporadic cases were reported in spring. The number of both endemic and sporadic cases reported peaked in October and November, but importantly a secondary peak in reporting of sporadic cases in April was found. In non-endemic areas, summer was the lowest risk season whilst in endemic areas, autumn was the lowest risk season. Two clusters of sporadic cases were identified, one in South Australia (P=0.022) during the period 22 May to 2 June 2012 and another in New South Wales (P=0.059) during the period 9 October to 29 November 2012. Endemic and sporadic cases did not differ with respect to neuter status (P=0.188), sex (P=0.205), case outcome (P=0.367) or method of diagnosis (P=0.413). However, sporadic cases were 4.2-times more likely to be dogs than cats (P<0.001). The endemic tick paralysis zone described is consistent with previous anecdotal reports. Sporadic cases reported outside this zone might be due to a history of pet travel to endemic areas, small foci of I. holocyclus outside of the endemic zone, or in the case of southern areas, tick paralysis caused by I. cornuatus.

Mixed methods inquiry into traditional healers' treatment of mental, neurological and substance abuse disorders in rural South Africa.

2017-01-01

Traditional healers are acceptable and highly accessible health practitioners throughout sub-Saharan Africa. Patients in South Africa often seek concurrent traditional and allopathic treatment leading to medical pluralism. We studied the cause of five traditional illnesses known locally as "Mavabyi ya nhloko" (sickness of the head), by conducting 27 in-depth interviews and 133 surveys with a randomly selected sample of traditional healers living and working in rural, northeastern South Africa. These interviews were carried out to identify treatment practices of mental, neurological, and substance abuse (MNS) disorders. Participating healers were primarily female (77%), older in age (median: 58.0 years; interquartile range [IQR]: 50-67), had very little formal education (median: 3.7 years; IQR: 3.2-4.2), and had practiced traditional medicine for many years (median: 17 years; IQR: 9.5-30). Healers reported having the ability to successfully treat: seizure disorders (47%), patients who have lost touch with reality (47%), paralysis on one side of the body (59%), and substance abuse (21%). Female healers reported a lower odds of treating seizure disorders (Odds Ratio (OR):0.47), patients who had lost touch with reality (OR:0.26; p-value<0.05), paralysis of one side of the body (OR:0.36), and substance abuse (OR:0.36) versus males. Each additional year of education received was found to be associated with lower odds, ranging from 0.13-0.27, of treating these symptoms. Each additional patient seen by healers in the past week was associated with roughly 1.10 higher odds of treating seizure disorders, patients who have lost touch with reality, paralysis of one side of the body, and substance abuse. Healers charged a median of 500 South African Rand (~US$35) to treat substance abuse, 1000 Rand (~US$70) for seizure disorders or paralysis of one side of the body, and 1500 Rand (~US$105) for patients who have lost touch with reality. While not all healers elect to treat MNS disorders, many continue to do so, delaying allopathic health services to acutely ill patients.

Hypoparathyroidism and paralysis of the recurrent laryngeal nerve (RLN) still remain the most frequent specific complications of thyroid surgery. This study evaluates the effects of employment of a recently introduced device (LigaSure™ Small Jaw, LSJ), compared to the traditional clamp-and-tie (CT) technique, on the short- and long-term outcome of the patients who underwent thyroidectomy. This prospective, randomized study included 190 patients enrolled from October 2011 to July 2013. The numbers of patients in the LSJ group and the CT group were both 95. We studied the following: operative times, intraoperative and postoperative blood losses, intact parathormone (iPTH) and calcium serum levels, and the incidence of RLN paralysis. The two cohorts were homogeneous for age, sex, surgical indication, BMI, ASA score, and estimated thyroid volume. Operation time has been 73.90 ± 23.35 min in group CT and 60.20 ± 22.36 min in group LSJ (p = 0.002). Intraoperative blood losses have been 47 ± 18 ml in group CT and 38 ± 14 in group LSJ (p = 0.002), while postoperative blood losses have been 45 ± 21 ml in group CT and 40 ± 20 in group LSJ (p = 0.105). The mean calcium blood level in group CT has been 8.12, 7.79, and 7.92 mg/dl in the first, second, and third postoperative days, respectively, as well as 8.26, 7.97, and 8.22 mg/dl for group LSJ (p > 0.05). Basal and post-thyroidectomy iPTH levels have been 46.49 and 23.64 pg/ml in group CT (Δ = 49.15 %), as well as 51.06 and 27.73 (Δ = 45.69 %) in group LSJ (p > 0.05). Permanent RLN paralysis was 1.05 % in LSJ group and 0 % in CT group. The employment of LSJ reduces in a statistically significant way both operative times and intraoperative blood losses. No significant differences were found as far as postoperative RLN paralysis and hypoparathyroidism.

Objective: The study was conducted to investigate the antibacterial and anthelmintic activities and to determine total phenolic contents of methanolic extract of Piper betel leaves. Materials and Methods: The extract was subjected to assay for antibacterial activity using both gram positive and gram negative bacterial strains through disc diffusion method; anthelmintic activity with the determination of paralysis and death time using earthworm (Pheritima posthuma) at five different concentrations and the determination of total phenolic contents using the Folin-ciocalteau method. Results: The extract showed significant (p<0.01) zone of inhibitions against gram positive Staphylococcus aureus [(6.77±0.25) mm] and Gram negative Escherichia coli [(8.53±0.25) mm], Salmonella typhi [(5.20±0.26) mm], Shigella dysenteriae [(11.20±0.26) mm] compared to positive control Azithromycin (ranging from 20.10±0.17 to 25.20±0.35 mm) while no zone inhibitory activity was found for both the extract and the standard drug against Gram positive Bacillus cereus. The extract also showed potent anthelmintic activity requiring less time for paralysis and death compared to the standard drug albendazole (10 mg/ml). At concentrations 10, 20, 40, 60 and 80 mg/ml, leaves extract showed paralysis at mean time of 9.83±0.60, 8.50±0.29, 6.60±0.17, 6.20±0.44 and 4.16±0.60; death at 11.33±0.88, 9.67±0.33, 7.83±0.17, 7.16±0.60 and 5.16±0.72 minutes, respectively. Whereas the standard drug showed paralysis and death at 19.33±0.71 and 51.00±0.23 minutes respectively. The extract confirmed the higher concentration of phenolic contents (124.42±0.14 mg of GAE /g of extract) when screened for total phenolic compounds. Conclusion: As results confirmed potential antibacterial and anthelmintic activities of Piper betel leaves extract, therefore it may be processed for further drug research. PMID:25386394

To establish the benefit of ansa cervicalis-recurrent laryngeal nerve reinnervation (ANSA-RLN) for the management of dysphonia secondary to unilateral vocal cord paralysis (UVCP) in children. Children treated with ANSA-RLN for the management of dysphonia secondary to unilateral vocal fold immobility will have superior acoustic, perceptual, and stroboscopic outcomes compared to injection laryngoplasty and observation. Retrospective case-series chart review. Laryngeal, perceptual, and acoustic analysis of dysphonia was performed in 33 children (age 2-16 years) diagnosed with UVCP. Comparison of pre-post function for treatment groups (no treatment, injection laryngoplasty, ANSA-RLN) with additional comparison between gestational ages, age at initial evaluation, and gender were examined. Perceptual measures included Pediatric Voice Handicap Index (pVHI) and Grade, Roughness, Breathiness, Asthenia, Strain (GBRAS) perceptual rating. Objective measures included semitone (ST) range, jitter%, shimmer%, noise-to-harmonic ratio, voicing, and maximum phonation time. Post-treatment, pVHI, jitter%, and ST were significantly improved for ANSA-RLN subjects compared to injection subjects. Improved function (laryngeal diadochokinesis, pVHI, GRBAS, and/or acoustic) was observed in all ANSA-RLN subjects who had vocal fold paralysis as the only laryngeal diagnosis. This study presents one of the largest studies of pediatric vocal fold paralysis diagnosis and treatment. The study looks at the spectrum of function in patients with UVCP and looks at the outcomes of options: no treatment, injection laryngoplasty, and ANSA-RLN. Although surgical outcomes vary, both injection laryngoplasty and ANSA-RLN show benefit in laryngeal function, voice stability, voice capacity, perceptual rating, and pVHI scores. Both injection laryngoplasty and ANSA-RLN showed improvements post-treatment, and should be considered for management of pediatric UVCP. However, the ANSA-RLN group showed better and longer-lasting perceptual and acoustic parameters in comparison with the injection and control groups. Reinnervation, even long term after the onset of vocal fold paralysis, should be considered a viable permanent treatment for pediatric UVCP. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Vocal fold paralysis following surgical ductal closure in extremely low birth weight infants: A case series of feeding and respiratory complications

PubMed Central

Malcolm, William F.; Hornik, Christoph; Smith, P. Brian; Evans, Adele; Cotten, C. Michael

2010-01-01

Surgical closure of a Patent Ductus Arteriosus (PDA) continues to be frequent among Extremely Low Birth Weight (ELBW) infants, despite improvements in the medical management of PDA’s and rising questions about its pathophysiologic role. Among other possible complications of this surgical intervention, left vocal fold paralysis (LVFP) has been reported. Only more recently, however, neonatologists are realizing the frequency and impact of this complication on chronic respiratory and feeding difficulties in the ELBW population. In this case series, we describe the clinical course of three sets of multiple births, for which at least one infant underwent surgical closure of his PDA and subsequently developed feeding and/or respiratory difficulties due to LVFP, and compare them to their respective siblings who did not sustain this complication.

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.

For 7% of people with Bell's palsy, facial impairment is permanent. The case study patient was a 48-year-old female who had no recovery from paralysis 12 weeks after onset. Goals were to restore facial sensory-motor functions, functional abilities and reduce depression. Facial paralysis was assessed by clinical observations, the Facial Disability Index and Beck Depression Index. Complementary interventions of aromatherapy, reflexology and electro-acupuncture were used with common physical agent modalities in an intensive home activity and exercise programme. The patient had 100% return of function and resolution of depression after 10 days of intervention. The limitation of this study is that it was a retrospective case study and the investigators reconstructed the case from clinical notes. Further research using a prospective approach is recommended to replicate this study. 2009 John Wiley & Sons, Ltd

Enterovirus 74 (EV74) is a rarely detected viral infection of children. In 2010, EV74 was identified in New Zealand in a 2 year old child with acute flaccid paralysis (AFP) through routine polio AFP surveillance. A further three cases of EV74 were identified in children within six months. These cases are the first report of EV74 in New Zealand. In this study we describe the near complete genome sequence of four EV74 isolates from New Zealand, which shows only limited sequence identity in the non-structural proteins when compared to the other two known EV74 sequences. As is typical of enteroviruses multiple recombination events were evident, particularly in the P2 region and P3 regions. This is the first complete EV74 genome sequenced from a patient with acute flaccid paralysis. PMID:24098514

Observations on cardiovascular and neuroendocrine disturbance in the Guillain-Barré syndrome

PubMed Central

Davies, A. G.; Dingle, H. R.

1972-01-01

Cardiovascular disturbances were found to be a common feature of patients with the Guillian-Barré syndrome who were severely paralysed, requiring assisted ventilation. Glycosuria was noted in association with these disturbances, and in five patients investigated we found impaired glucose tolerance tests at the height of the paralysis. Catecholamine and 17-hydroxycorticosteroid urinary excretions were found to be high in four patients investigated when the neuropathy was most severe, and in one patient plasma cortisol levels were high with loss of diurnal variation. With recovery from paralysis cardiovascular disturbances became less marked, catecholamine and 17-hydroxycorticosteroid urinary excretions reverted to normal, glucose tolerance improved but remained abnormal in three patients during the period of observation. It is suggested that increased levels of catecholamines and cortisol contributed to the development of impaired glucose tolerance and cardiovascular disturbances. PMID:4113954

Sariego, Jack

2010-01-01

This study was performed retrospectively to evaluate the incidence of documented vocal fold injury as a result of elective endotracheal intubation during general surgical procedures. Medical record review was performed at a single institution and all surgical cases reviewed which required endotracheal intubation in the nonemergent setting between April 1, 2003 and August, 31, 2007. Cases with unexpected and documented vocal fold immobility postoperatively formed the study cohort, and data were gathered regarding diagnosis and procedures performed. Of 23,010 general surgery cases performed during the study period, only seven documented cases of vocal fold paralysis were discovered (0.03%). There were five women and two men in the group; all were adults. Only one patient had a primary diagnosis related to the head and neck. Comorbidities were recorded as well, but there were no statistically significant patterns discerned. Furthermore, during the study period, a total of 31 patients overall (both surgical and nonsurgical) were admitted who carried a primary diagnosis of vocal fold paralysis. Therefore, the study cohort therefore constituted 22.6% of this total. Finally, cohort patients spent a total of 150 days in hospital during the study period; this length of stay (an average of 16.7 hospital days per patient) was significantly longer than the average of 5.1 days, presumably at least in part related to the vocal paralysis.

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.

Diaphragmatic paralysis first suggested as a therapeutic measure in lung disease by Steurtz (1911), who did simple phrenicotomy. Felix (1922) showed in 25% of cases this was ineffective owing to the presence of an accessory phrenic, and suggested phrenic exairesis, i.e. complete evulsion of the phrenic nerve. Goetze (1922) suggested radical phrenicotomy, i.e. division of the phrenic and excision of the nerve to the subclavius. Effects of diaphragmatic paralysis.—The diaphragm rises to the full expiratory position (4-8 cm.). Paradoxical movement (Kienböch's phenomenon) on affected side. Muscle atrophies. Collapse of the lung produced, affecting base and apex also. Lung volume reduced by ⅙th to ⅓rd. Physical signs.—Indrawing of the epigastrium. Thoracic breathing. Litten's sign absent. Less resistance to abdominal palpation on affected side. Diminished resonance at border of sternum and at base. Deficient inspiratory murmur at base. Radiography.—Paradoxical movement.

On the basis of in vitro studies, the antioxidant nutrients vitamins E and C are postulated to interact in vivo. We developed a guinea pig model to evaluate the combined deficiency of vitamins E and C in vivo. Weanling guinea pigs were fed a control diet or a vitamin E-deficient diet for 14 d, after which one-half of each group had vitamin C removed from their diet, thus creating 4 diet groups. Some animals were observed for clinical signs. Others were killed for evaluation. Of 21 guinea pigs that were observed after being fed the diet deficient in both vitamins, 8 died 9 +/- 2 d (x +/- SD) after starting the diet. Eight additional guinea pigs developed a characteristic syndrome at 11 +/- 3 d. First, they became paralyzed in the hind limbs. Within a few hours, the paralysis progressed to include all 4 limbs and caused difficulty in breathing, which would have caused death had the animals not been euthanized. Histopathologic evaluation did not identify a lesion in the muscles or nervous system that could account for the paralysis. Biochemical measurements confirmed the deficiencies and indicated that the double deficiency caused lipid peroxidation in the central nervous system. A distinct clinical syndrome of combined vitamin E and vitamin C deficiency occurs in guinea pigs. This syndrome indicates that these antioxidant vitamins are related in vivo. We speculate that acute oxidative injury in the central nervous system underlies the clinical syndrome.

Medical records of 10 dogs in which fungal infection was diagnosed between 1982 and 1990 were reviewed. In each dog, infection was determined to be caused by a single species of fungus, either Aspergillus terreus, Penicillium sp, Paecilomyces sp, Chrysosporium sp, or Pseudallescheria boydii. Nine dogs were German Shepherd Dogs; 1 was a German Shepherd Dog cross, and 9 were females. The most common clinical signs were signs of neck or back pain (9 dogs), weight loss (7 dogs), anorexia (6 dogs), pyrexia (6 dogs), paresis (3 dogs), and paralysis (3 dogs). All 10 dogs had evidence of multiple sites of diskospondylitis. Urine sediment was examined in 6 dogs, and all 6 had fungal hyphae. Urine samples from these dogs produced a medium to heavy pure growth of fungi when placed on Sabaraud's medium. Predisposing causes were not identified in any of the dogs. Four dogs were euthanatized immediately after diagnosis because of paralysis or paresis. The other 6 dogs were treated, and 4 of the 6 received itraconazole. One dog was euthanatized for an unrelated problem after 21 months of treatment; 1 dog was still alive after 4 years of continuous treatment with itraconazole. The other 4 dogs were euthanatized because of eventual paralysis or paresis. Our results suggest that German Shepherd Dogs are predisposed to infection with opportunistic fungi, possibly because of a specific inability to mount an effective response. This predisposition needs to be further studied.

In Argentina, bee virus studies are still incipient, and there are no studies regarding the climatic effect. The aim of this study was to assess and compare the presence of honeybee viruses in different climatic regions from Argentina. A total of 385 colonies distributed in five Argentinean eco-regions were examined to evaluate the percentage of infestation with Varroa destructor and 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; Kashmer bee virus, KBV; Israeli acute bee paralysis virus, IAPV; and Sacbrood bee virus, SBV) after honey yield. Two viruses, KBV and IAPV, were not detected. The other five viruses were found in different prevalences: DWV (35%), ABPV (21.5%), BQCV (8.0%), CBPV (2.2%), and SBV (1.1%). We found double and triple viral associations in approximately 25% of the sampled colonies. The mean V. destructor infestation in the colonies prior to the acaricide treatment was 7.12%±8.7%. The knowledge of the prevalence of these viruses in the region and their relation with the mite and other possible influencing factors is important for preventing colony losses. Further studies are necessary to identify the risk factors associated with virus presence and its relationship with other pathogens such as V. destructor.

To determine the functional recovery in patients with severe transient peripheral facial motor paralysis (Bell palsy). Prospective controlled trial. Academic medical center. Blink recovery was studied in 2 groups of severely affected Bell palsy patients during a follow-up period of 84 weeks. The patients in one group received prednisolone within the first week after the onset of symptoms. No medication was given to the other group. A control group of healthy subjects was also included. Simultaneous orbicularis oculi muscle activity and eyelid kinematics were recorded by surface electromyographic (EMG) recording and eyelid search coils, respectively. At the beginning of the paralysis, very little integrated orbicularis oculi muscle activity and eyelid movement was measured at the palsied side of the face. Thirteen weeks later, the integrated orbicularis oculi EMG and functional blink recovery gradually improved until 39 weeks. Beyond, only the integrated orbicularis oculi EMG slightly increased. At 84 weeks, the integrated orbicularis oculi EMG was significantly larger in the prednisolone group compared with the control group. The integrated EMG of the nonmedicated group recovered to normal values. Curiously enough, the functional blink recovery at the palsied side remained reduced to 64% compared with the healthy controls in the prednisolone-treated group and to 36% in the nonmedicated group. The authors demonstrate that prednisolone significantly increased the orbicularis oculi muscle activity and significantly improved functional blink recovery in severely affected Bell palsy patients. However, the increase of muscle activity was insufficient to restore functional blinking to normal values.

Objective Bell's palsy is a cranial nerve VII dysfunction that renders the patient unable to control facial muscles from the affected side. Nevertheless, some patients have reported cutaneous changes in the paretic area. Therefore, cutaneous sensibility changes might be possible additional symptoms within the clinical presentation of this disorder. Accordingly, the aim of this research was to investigate the relationship between cutaneous sensibility and facial paralysis severity in these patients. Study Design Prospective longitudinal cohort study. Settings Tertiary care medical center. Subjects and Methods Twelve acute-onset Bell's palsy patients were enrolled from March to September 2009. In addition, 12 sex- and age-matched healthy volunteers were tested. Cutaneous sensibility was evaluated with pressure threshold and 2-point discrimination at 6 areas of the face. Facial paralysis severity was evaluated with the House-Brackmann scale. Results Statistically significant correlations based on the Spearman's test were found between facial paralysis severity and cutaneous sensitivity on forehead, eyelid, cheek, nose, and lip ( P < .05). Additionally, significant differences based on the Student's t test were observed between both sides of the face in 2-point discrimination on eyelid, cheek, and lip ( P < .05) in Bell's palsy patients but not in healthy subjects. Conclusion Such results suggest a possible relationship between the loss of motor control of the face and changes in facial sensory information processing. Such findings are worth further research about the neurophysiologic changes associated with the cutaneous sensibility disturbances of these patients.

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.

Hasan, Zeenat R; Sorensen, G Brent

2013-01-01

Intraabdominal hypertension and abdominal compartment syndrome have been increasingly recognized as significant causes of morbidity and mortality in both medical and surgical patients. The gold standard remains surgical intervention; however, nonoperative approaches have been investigated less. Here, we describe the successful treatment of a severe acute case by intubation, nasogastric decompression, and paralysis--a novel approach not previously described in the literature. After the patient underwent laparoscopic bilateral component separation and repair of a large recurrent ventral hernia with a 20 30-cm Strattice mesh (LifeCell Corp, Branchburg, NJ), acute renal failure developed within 12 hours postoperatively, and was associated with oliguria, hyperkalemia, and elevated peak airway and bladder pressures. The patient was treated nonoperatively with intubation, nasogastric tube decompression, and paralysis with a vecuronium drip. Rapid reversal was seen, avoiding further surgery. Within 2 hours after intubation and paralysis, our patient's urine output improved dramatically with an initial diuresis of approximately 1 L, his bladder pressures decreased, and within 12 hours his creatinine level had normalized. Although surgical intervention has traditionally been thought of as the most effective--and thus the gold standard--for abdominal compartment syndrome, this preliminary experience demonstrates nonoperative management as highly efficacious, with the added benefit of decreased morbidity. Therefore, nonoperative management could be considered first-line therapy, with laparotomy reserved for refractory cases only. This suggests a more complex pathology than the traditional teaching of congestion and edema alone.

Botulism caused by type F botulinum toxin accounts for less than 0.1% of all human botulism cases and is rarely reported in the literature. A 45-year-old woman presented to an emergency department complaining of blurred vision, difficulty focusing, and dysphagia. The treating physician initially considered the possibility of paralytic shellfish poisoning due to a report of shellfish ingestion, which was later determined to be frozen shrimp and a can of tuna, but no gastroenteritis or paresthesias were present. During the emergency department observation, the patient developed respiratory distress with hypercapnea and required intubation and mechanical ventilation. Within hours, ptosis, mydriasis, and weakness in the arms and legs developed. Bivalent (A, B) botulinum antitoxin was administered approximately 24 h from the onset of initial symptoms, but over the next two days complete paralysis progressed to the upper and lower extremities. Shortly thereafter a stool toxin assay demonstrated the presence of type F botulinum toxin. The patient subsequently received an experimental heptavalent botulinum antitoxin on hospital day 7 but paralysis was already complete. Her three-week hospital course was complicated by nosocomial pneumonia and a urinary tract infection, but she gradually improved and was discharged to a rehabilitation facility. Anaerobic cultures and toxin assays have yet to elucidate the source of exposure. We report a rare case of type F botulism believed to be foodborne in etiology. Administration of bivalent botulinum antitoxin did not halt progression of paralysis.

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 < .05). 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.

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.
