Pranav Deshpande, M Sabarimalai Manikandan
Accurate determination of glottal instants and electroglottographic (EGG) parameters is most important in voice pathology analysis including multiple voice disorders: neurological, functional, and laryngeal diseases. In this paper, we present a new effective method for reliable detection of glottal instants and EGG parameters from an EGG signal composed of voiced and non-voice segments. In the first stage, we present an adaptive variational mode decomposition (aVMD) based algorithm for suppressing low-frequency artifacts and additive high-frequency noises...

Huntington's disease (HD) is an incurable, devastating neurodegenerative disease with a known genetic background and autosomally dominant inheritance pattern. HTT gene mutation (mHTT) is associated with polymorphic fragment elongation above 35 repeats of the CAG triplet. The mHTT product is an altered protein with a poly-Q elongated fragment, with the highest expression determined in the central nervous system (CNS) and with differentiated expression outside the CNS. A drastic loss of striatal and deeper layers of the cerebral cortex neurons was determined in the CNS, but muscle and body weight mass loss with dysfunction of many organs was also observed...

BACKGROUND AND PURPOSE: The National Institutes of Health Stroke Scale (NIHSS) correlates with presence of large anterior vessel occlusion (LAVO). However, the application of the full NIHSS in the prehospital setting to select patients eligible for treatment with thrombectomy is limited. Therefore, we aimed to evaluate the prognostic value of simple clinical selection strategies. METHODS: Data from the Safe Implementation of Thrombolysis in Stroke International Stroke Thrombolysis Registry (January 2012-May 2014) were analyzed retrospectively...

PURPOSE: While the presence of dysphagia following partial glossectomy has been widely reported, there is insufficient quality evidence to guide clinical decision making about the treatment of this disorder. This study investigated a novel dysphagia rehabilitation approach using ultrasound tongue imaging for patient training. METHOD: Initially, a pilot study was conducted to investigate the feasibility of ultrasound visual feedback during swallow tasks. The protocol was then replicated using a single-case experimental designed study to investigate therapeutic effect...

OBJECTIVE The aim of this study was to confirm the feasibility of an innovative transoral robotic surgery (TORS), using the da Vinci Surgical System, for patients with sellar tumors. This technique was designed to offer a new minimally invasive approach, without soft-palate splitting, that avoids the rhinological side effects of classic endonasal approaches. METHODS The authors performed a prospective study of TORS in patients with symptomatic sellar tumors. Specific anatomical features were required for inclusion in the study and were determined on the basis of preoperative open-mouth CT scans of the brain...

OBJECTIVES: Dysphonia due to unilateral vocal fold paralysis (UVFP) can be characterized by hoarseness and weakness, resulting in a significant impact on patients' activity and participation. Voice therapy provided by a speech-language pathologist is designed to maximize vocal function and improve quality of life. The purpose of this paper is to systematically review literature surrounding the effectiveness of speech-language pathology intervention for the management of UVFP in adults...

The mechanics of vocal fold contact during phonation is known to play a crucial role in both normal and pathological speech production, though the underlying physics is not well understood. Herein, a viscoelastic model of the stresses during vocal fold contact is developed. This model assumes the cover to be a poroelastic structure wherein interstitial fluid translocates in response to mechanical squeezing. The maximum interstitial fluid pressure is found to generally increase with decreasing viscous dissipation and/or decreasing tissue elasticity...

Increased pain and/or discomfort during chewing, speaking, and swallowing have been commonly reported by patients with Temporomandibular Dysfunction (TMD). Speech-language pathology therapy (orofacial myofunctional therapy - OMT) has been proposed as part of the treatment for this condition; however, it is a modality that should be introduced when the TMD context and the pain are not accentuated, so that they do not prevent or hinder the performance of exercises. The aim of this study was to analyze the effect of OMT on the treatment of patients with TMD, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), after analgesia with low-level laser therapy (LLLT), regarding orofacial myofunctional conditions (OMC) and the perception of TMD symptoms...

INTRODUCTION: The use of frequency-based analysis as an accurate method of voice analysis motivated us to evaluate the voice qualities of healthy versus dysphonic Iranian people. METHODS: Two hundred normal and dysphonic participants aged between 20 and 50 years in either gender were divided into four different equal groups. For the tasks, 5-second prolongation of vowel /a/ and a sample of reading text were used for the analysis. "Speech Tool" software was employed for Cepstral peak prominence (CPP) and cepstral peak prominence-smoothed (CPPS) analyses...

AIMS: To (1) characterize early therapy services for preterm infants in the first two years of life, and (2) define factors related to accessing early therapy services. METHODS: Therapy utilization after discharge from the neonatal intensive care unit (NICU) was tracked in 57 infants born ≤30 weeks gestation from 2007 to 2010. Participants returned for developmental testing at two years. Factors related to early therapy utilization were explored. RESULTS: Fifty-two (91%) infants received a referral for therapy at NICU discharge but only 44 (77%) received at least one type of therapy during the first two years of life...

Posterior fossa syndrome (PFS), or cerebellar mutism syndrome (CMS), is a collection of neurological symptoms that occur following surgical resection of a posterior fossa tumour, and is characterised by either a reduction or an absence of speech. Some authors suggest that CM is only one symptom of the CMS complex that also includes ataxia, hypotonia and irritability as well as cranial nerve deficits, neurobehavioral changes and urinary retention or incontinence. It is seen almost exclusively in children. In 1985 Rekate et al...

PURPOSE: Cephalometric evaluation of craniofacial and craniopharyngeal morphology is important for understanding the factors affecting velopharyngeal dysfunction (VPD) in patients with palatal anomalies. MATERIALS AND METHODS: In this study, 366 patients with VPD were retrospectively stratified into cleft lip and palate (CLP), cleft palate (CP), submucous cleft palate (SMCP), occult submucous cleft palate (OSMCP), and non-CP groups. Lateral cephalometrics were used to assess craniofacial, craniopharyngeal, and velopharyngeal anatomy...

Context • A variety of rehabilitation-based interventions are currently available for individuals with physical impairments resulting from neurological conditions, including physiotherapy, occupational therapy, and speech language pathology. Many individuals find participation in those therapies to be challenging. Alternative therapies have emerged as beneficial adjunctive treatments for individuals undergoing neurological rehabilitation, including music therapy (MT). Objective • The study intended to identify and collate systematically the evidence on MT interventions that address physical improvements in a rehabilitative setting...

Over 60% of all patients with dura mater graft-associated Creutzfeldt-Jakob disease (dCJD) have been diagnosed in Japan. The incubation period has ranged from 1 to 30 years and the age at onset from 15 to 80 years. Here, we report a 77-year-old male Japanese autopsied dCJD case with the longest incubation period so far in Japan. He received a cadaveric dural graft at the right cranial convexity following a craniotomy for meningioma at the age of 46. At 30 years post-dural graft placement, disorientation was observed as an initial symptom of dCJD...
