Sarah Helen Evans, Mark William Cameron, Justin Michael Burton
Hypertonia is the abnormal increase in muscle tone as a result of upper motor neuron lesions. There are three following clinical types: spasticity, dystonia, and rigidity. Management of hypertonia is individualized and should be directed by the patient and/or family׳s goals of care as well as the underlying cause of the hypertonia. Treatment options include stretching, strengthening, positioning, oral medications, botulinum toxin injections, phenol injections, as well as surgical procedures. Without effective management, hypertonia can result in muscle imbalance, abnormal movement patterns, pain, joint contracture, joint deformity, and ultimately negatively impact a patient׳s function...

The ability to reproduce novel words is a sensitive marker of language impairment across a variety of developmental disorders. Nonword repetition tasks are thought to reflect phonological short-term memory skills. Yet, when children hear and then utter a word for the first time, they must transform a novel speech signal into a series of coordinated, precisely timed oral movements. Little is known about how children's oromotor speed, planning and co-ordination abilities might influence their ability to repeat novel nonwords, beyond the influence of higher-level cognitive and linguistic skills...

The aim of this study was to compare current application, practice patterns, clinical outcomes, and professional attitudes of dysphagia practitioners regarding electrical stimulation (e-stim) therapy with similar data obtained in 2005. A web-based survey was posted on the American Speech-Language-Hearing Association Special Interest Group 13 webpage for 1 month. A total of 271 survey responses were analyzed and descriptively compared with the archived responses from the 2005 survey. Results suggested that e-stim application increased by 47% among dysphagia practitioners over the last 10 years...

Light subunit of mushroom tyrosinase (LSMT) is a protein of unknown function from mushroom Agaricus bisporus that has been demonstrated to permeate through rat intestine ex vivo. Thus, it can be absorbed in the intestine, thereby holding a promise as a drug carrier for oral administration, similar to HA-33 protein from botulinum, one of the closest structural homologs of LSMT. However, the safety of LSMT should be ensured prior to its use. Here, we described biological response of LSMT upon weekly intraperitoneal administration of 50 μg/day to the Balb/c mice for 12 weeks...

BACKGROUND The body of literature on oral motor and swallowing disorders in patients with ataxia telangiectasia (AT) is limited. CASE REPORT The purpose of this study was to characterize oral motor and swallowing disorders in two siblings with AT, based on oral motor and swallowing assessments. Specific procedures were applied for oral motor and swallowing assessments and both patients underwent videofluoroscopy (VFS). Case 1 presented vocal instability, change in postural control during feeding; food retention in oral cavity; slower oral transit time; and multiple swallowing (signs for solid and liquid)...

TRPC (transient receptor potential cation channel subfamily C) members are nonselective monovalent cation channels and control Ca2+ inflow. In this study, immunohistochemistry for TRPC1, TRPC3, and TRPC4 was performed on rat oral and craniofacial structures to elucidate their distribution and function in the peripheries. In the trigeminal ganglion (TG), 56.1, 84.1, and 68.3% of sensory neurons were immunoreactive (IR) for TRPC1, TRPC3, and TRPC4, respectively. A double immunofluorescence method revealed that small to medium-sized TG neurons co-expressed TRPCs and calcitonin gene-related peptide...

The transgenic mouse model R6/2 exhibits Huntington's disease (HD)-like deficits and basic pathophysiological similarities. We also used the pheochromocytoma-12 (PC12)-cell-line-model to investigate the effect of laquinimod on metabolic activity. Laquinimod is an orally administered immunomodulatory substance currently under development for the treatment of multiple sclerosis (MS) and HD. As an essential effect, increased levels of BDNF were observed. Therefore, we investigated the therapeutic efficacy of laquinimod in the R6/2 model, focusing on its neuroprotective capacity...

Cancer has emerged as a global threat with challenges for safe chemotherapeutics. Most of the currently available anti-cancer drugs exhibit significant toxicity. Amongst novel agents, interferons have exhibited anti-proliferative and cytoprotective roles. However, due to stability drawbacks of interferons, we have identified an interferon inducer DEAE-Dextran, which resolves the stability issues. Based on the previous history of toxicity pertaining to the current chemotherapeutic agents, it is equally essential to determine the safety of DEAE-Dextran...

Carpal tunnel syndrome (CTS) is a common and sometimes challenging condition, which causes pain; paresthesia; tingling of the thumb, index and long fingers; and even thenar weakness in the hands. The effectiveness of corticosteroid injections seems to be transient, and there is a lack of information around long-term effects in previous studies. In recent years, platelet-rich plasma (PRP) has proven to bean alternative as it encourages tissue regeneration. We hereby describe a patient with CTS showing significant improvements in electrophysiological parameters after receiving PRP injections...

Infants and children with esophageal atresia commonly present with swallowing dysfunction or dysphagia. Dysphagia can lead to a range of significant consequences such as aspiration pneumonia, malnutrition, dehydration, and food impaction. To improve oral intake, the clinical diagnosis of dysphagia in patients with esophageal atresia should focus on both the pharynx and the esophagus. To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagus, a detailed understanding of normal and abnormal deglutition is required through the use of adequate and objective assessment techniques...

Pallidal stimulation has been the usual surgical treatment for dystonia in the last decades. The continuous investigation of the physiopathology and the motor pathways involved leads to the search for complementary targets to improve results. The authors present the case of a 37-year-old woman who had suffered from idiopathic hemidystonia with hyperkinetic and hypokinetic movements for 11 years, and who was treated with deep brain stimulation. A brief literature review is also provided. The globus pallidus internus and the ventral intermediate/ventral oral posterior complex of the thalamus were stimulated separately and simultaneously for 3 months and compared using the Burke-Fahn-Marsden Dystonia Rating Scale and the Global Dystonia Severity Rating Scale, with a 3...

Fibromyalgia is a chronic syndrome characterized by widespread musculoskeletal pain and an extensive array of other symptoms including disordered sleep, fatigue, depression and anxiety. Important factors involved in the pathogenic process of fibromyalgia are inflammation and oxidative stress, suggesting that ant-inflammatory and/or antioxidant supplementation might be effective in the management and modulation of this syndrome. Recent evidence suggests that melatonin may be suitable for this purpose due to its well known ant-inflammatory, antioxidant and analgesic effects...

Prosthodontic treatment success depends on patients' ability to adapt to an altered oral environment containing removable prostheses. We investigated adaptive chewing-related brain activity changes in response to a new oral environment. Twenty-eight fully dentate subjects (mean age: 28.6 years) wore experimental denture-base palatal plates (3-mm thick), for 7 days. We measured food mixing ability and cycle time, and assessed brain activity by functional magnetic resonance imaging during chewing at pre-insertion (Day 0), and immediately (Day 1), 3 days (Day 3), and 7 days (Day 7) after insertion...

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model remains the most commonly used animal model of Parkinson's disease (PD). There are three MPTP-treatment schemes: acute, subacute and chronic. Considering the advantages of the period and similarity to PD, the subacute model was often chosen to assess the validity of new candidates, but the changes caused by the subacute MPTP treatment and the appropriate positive control for this model remain to be further confirmed. The aim of this study was: 1 to estimate the value of the subacute MPTP mouse model in aspects of behavioral performance, biochemical changes and pathological abnormalities, and 2 to find effective positive drugs...

The tongue can move freely and is important in oral motor functions. Tongue movement must be coordinated with movement of the hyoid, mandible, and pharyngeal wall, to which it is attached. Our previous study using isolated brainstem-spinal cord preparations showed that application of N-methyl-D-aspartate induces rhythmic activity in the hypoglossal nerve that is coincident with rhythmic activity in the ipsilateral trigeminal motor nerve. Partial or complete midline transection of the preparation only abolishes activity in the trigeminal motor nerve; therefore, the neuronal network contributing to coordinated activity of the jaw/tongue muscles is located on both sides of the preparation and sends motor commands to contralateral trigeminal motoneurons...

Primary motor cortex (M1) plasticity is involved in motor learning and stroke motor recovery, and enhanced by increasing monoaminergic transmission. Age impacts these processes but there is a paucity of systematic studies on the effects of monoaminergic drugs in older adults. Here, in ten older adults (age 61+ 4 years, 4 males), we determine the effects of a single oral dose of carbidopa/levodopa (DOPA), d-amphetamine (AMPH), methylphenidate (MEPH) and placebo (PLAC) on M1 excitability and motor training-induced M1 plasticity...
