Spastic dysphonia

Claire S Leblond, Alina Webber, Ziv Gan-Or, Fraser Moore, Alain Dagher, Patrick A Dion, Guy A Rouleau
Juvenile amyotrophic lateral sclerosis (jALS) is characterized by progressive upper and lower motor neuron degeneration leading to facial muscle spasticity, spastic dysarthria, and spastic gait with an early onset (before 25 years old). Unlike adult-onset amyotrophic lateral sclerosis (ALS), patients with jALS tend to have slower progression of motor neuron disease and prolonged survival to a normal life expectancy. Mutations in FUS gene have been reported in jALS,(1) including p.P525L mutation that has been consistently associated with early onset and aggressive presentation...

OBJECTIVES: Since the mid-20th century, one citation is given historical priority as the first description of spasmodic dysphonia (SD): Ludwig Traube's 1871 case of the "spastic form of nervous hoarseness." Our objective is to understand how this case serves as the foundation of understanding laryngeal movement disorders. METHODS: The original German paper was located and translated. Bibliographical and bibliometric methods are used to determine the citation history of this original source over the past 140 years...

Multiple system atrophy (MSA) is characterized clinically by parkinsonism, cerebellar, autonomic, and corticospinal features of variable severity. When the presentation is only parkinsonism, the disease might be difficult to differentiate from Parkinson's disease (PD). We present a case of an 80-year-old man with previous diagnosis of PD. One year after the diagnosis, he had a whiplash cervical trauma due to a tricycle accident caused by a hole in the road. This low-energy trauma caused an unstable C4-C5 cervical fracture with spinal cord injury, which required surgical decompression and stabilization...

Mutations in the TUBB4A gene have been identified so far in two neurodegenerative disorders with extremely different clinical features and course: whispering dysphonia, also known as dystonia type 4 (DYT4), and hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC). We describe a patient with slowly progressive spastic paraparesis, segmental dystonia, intellectual disability, behavioral problems, and evidence of permanent, incomplete myelination associated with progressive cerebellar atrophy...

A 48-year-old black male, of Nigerian heritage, presented with a 24-hour history of frontal headache of gradual onset. The headache characteristic was migranous, being described as throbbing in nature and located to the right frontal area with associated blurring of vision. Although similar to prior frequent headaches, there was now increasing unsteadiness on walking. Diagnosed 10 years earlier with Behçet's disease, the initial presentation was with oral and genital ulceration. Recurrent episodes of headache caused by neurological flare-ups resulted in a stroke at the age of 46 years...

Botulinum toxin (BTX), the exotoxin of the obligate anaerobe, Clostridium botulinum, is used to ameliorate pain and treat conditions associated with glandular, smooth and skeletal muscle overactivity. The benefits derived from the injection of BTX may be negated by unintended weakness of uninjected muscles. Performance of BTX injections may be facile, requiring only surface marking or clinical-localisation techniques but may be more technically demanding, necessitating the use of equipment, such as electromyography (EMG) or ultrasonography (U/S)...

Botulinum toxin has long been known for its paralytic effects on the human voluntary musculature via inhibition of acetylcholine release at neuromuscular junctions. Its original clinical use for the treatment of strabismus has expanded significantly to include neurological conditions related to muscle hyperactivity and/or spasticity (e.g., dystonia, spasticity, tics, tremor, dysphonia). Recently, botulinum toxin has been shown to impact autonomic disorders by acting at acceptors on glands and smooth muscle, and consequently it has been used in the management of a number of other conditions including hypersecretory disorders, pain syndromes, detrusor sphinchter dyssenergia or overactivity and gastointestinal smooth muscle/sphincter spasm; it may also reduce pain in patients for whom it is used to treat these and other primary conditions...

Botulinum neurotoxin type B (BT, BT-B) has been used as NeuroBloc/MyoBloc since 1999 for treatment of cervical dystonia, hyperhidrosis, spastic conditions, cerebral palsy, hemifacial spasm, bladder dysfunction, spasmodic dysphonia, sialorrhoea, anal fissures, piriformis syndrome, various pain conditions and cosmetic applications. Generally, its therapeutic effects are comparable to BT type A (BT-A). The adverse effect profiles of BT-B and BT-A, however, differ considerably. BT-B has been found to produce more regional as well as systemic anticholinergic adverse effects, such as dryness of mouth, accommodation difficulties, conjunctival irritation, reduced sweating, dysphagia, heartburn, constipation, bladder voiding difficulties and dryness of nasal mucosa...

Many surgical approaches have been developed for the treatment of adduction-type spasmodic dysphonia (SPD). We developed and performed a new type of surgical approach (autologous replacement of the vocal fold). Our new surgical technique increases the advantages and decreases the disadvantages of previous surgical procedures in three ways: (1) It has similar effects to the previous procedures in that it prevents contraction of the thyroarytenoid muscle. (2) It decreases vocal-fold tension, as in framework surgery...

Since its introduction in the late 1970s for the treatment of strabismus and blepharospasm, botulinum toxin (BoNT) has been increasingly used in the interventional treatment of several other disorders characterized by excessive or inappropriate muscle contractions. The use of this pluripotential agent has extended to a plethora of conditions including: focal dystonia; spasticity; inappropriate contraction in most sphincters of the body such as those associated with spasmodic dysphonia, esophageal achalasia, chronic anal fissure, and vaginismus; eye movement disorders; other hyperkinetic disorders including tics and tremors; autonomic disorders such as hyperhidrosis; genitourinary disorders such as overactive and neurogenic bladder, non-bacterial prostatitis and benign prostatic hyperplasia; and aesthetically undesirable hyperfunctional facial lines...

Strained, strangled, and tremulous vocal qualities that are typically seen in adductor spasmodic dysphonia (ADSD), voice tremor (Tremor), and the spastic dysarthria of amyotrophic lateral sclerosis (ALS) may sound similar and be difficult to differentiate. The purpose of this study was to determine if these vocal qualities of neurologic origin could be differentiated on the basis of acoustic and motor speech parameters. Three groups of subjects (ADSD, ALS, and Tremor) were analyzed by the Motor Speech Profile System (Kay Elemetrics, Lincoln Park, NJ) for fundamental frequency (Fo), standard deviation of Fo, diadochokinetic rate (ddk), standard deviation of ddk, mean intensity and standard deviation of ddk, frequency and amplitude variability in connected speech, and speaking rate in connected speech...

Seven women and two men with spastic dysphonia, ranging in age from 20 to 59 years, were studied to determine the cause and the means of development of the condition. The patients were examined by a laryngologist and, when feasible, by a psychiatrist or other medical specialist for coordination and corroboration of the diagnosis. Psychiatric observations were significant. A background of conflict with a parent or spouse was frequent and typical. In almost every case there were deep guilt feelings associated with something the patient had said to the person with whom he was in conflict...
