    Few speech disorders have been more controversial as to etiology and treatment as spasmodic dysphonia. This article reviews the historical background and origins of spasmodic dysphonia theories and the legacy of their implications on the current treatment of afflicted patients. The evolution and impact of "organic theories" is discussed and a personal perspective on the central nervous system investigations performed by the authors is briefly elucidated and their practical experience in managing spasmodic dysphonia patients is offered for the reader's consideration.

    This study investigated relationships between acoustical indices of spasmodic dysphonia and perceptual scaling judgments of voice attributes made by expert listeners. Audio-recordings of The Rainbow Passage were obtained from thirty one speakers with spasmodic dysphonia before and after a BOTOX injection of the vocal folds. Six temporal acoustic measures were obtained across 15 words excerpted from each reading sample, including both frequency of occurrence and percent time for (1) aperiodic phonation, (2) phonation breaks, and (3) fundamental frequency shifts. Visual analog scaling judgments were also obtained from six voice experts using an interactive computer interface to quantify four voice attributes (i.e., overall quality, roughness, brokenness, breathiness) in a carefully psychoacoustically controlled environment, using the same reading passages as stimuli. Number and percent aperiodicity and phonation breaks correlated significanly with perceived overall voice quality, roughness, and brokenness before and after the BOTOX injection. Breathiness was correlated with aperidocity only prior to injection, while roughness also correlated with frequency shifts following injection. Factor analysis reduced perceived attributes to two principal components: glottal squeezing and breathiness. The acoustic measures demonstrated a strong regression relationship with perceived glottal squeezing, but no regression relationship with breathiness was observed. Implications for an analysis of pathologic voices will be discussed.

    Full Text Available Michael P Cannito, Joel C Kahane, Lesya ChornaSchool of Audiology and Speech-Language Pathology, The University of Memphis, Memphis, TN, USAAbstract: Aging of the larynx is characterized by involutional changes which alter its biomechanical and neural properties and create a biological environment that is different from younger counterparts. Illustrative anatomical examples are presented. This natural, non-disease process appears to set conditions which may influence the effectiveness of botulinum toxin injection and our expectations for its success. Adductor spasmodic dysphonia, a type of laryngeal dystonia, is typically treated using botulinum toxin injections of the vocal folds in order to suppress adductory muscle spasms which are disruptive to production of speech and voice. A few studies have suggested diminished response to treatment in older patients with adductor spasmodic dysphonia. This retrospective study provides a reanalysis of existing pre-to-post treatment data as function of age. Perceptual judgments of speech produced by 42 patients with ADSD were made by two panels of professional listeners with expertise in voice or fluency of speech. Results demonstrate a markedly reduced positive response to botulinum toxin treatment in the older patients. Perceptual findings are further elucidated by means of acoustic spectrography. Literature on vocal aging is reviewed to provide a specific set of biological mechanisms that best account for the observed interaction of botulinum toxin treatment with advancing age.Keywords: vocal aging, adductor spasmodic dysphonia, botulinum toxin, voice quality, speech fluency

We also developed a Neurophysiological Scoring (NPS system which has utility in the treatment administration. Method and materials Data were gathered prospectively on voice improvement (self-rated 6 point scale, length of response and duration of complications (breathiness, cough, dysphagia and total voice loss. Injections were performed under electromyography (EMG guidance. NPS scale was used to describe the EMG response. Dose and unilateral/bilateral injections were determined by clinical judgment based on previous response. Time intervals between injections were patient driven. Results Low dose unilateral Dysport injection was associated with no significant difference in the patient's outcome in terms of duration of action, voice score (VS and complication rate when compared to bilateral injections. Unilateral injections were not associated with any post treatment total voice loss unlike the bilateral injections. Conclusion Unilateral low dose Dysport injections are recommended in the treatment of adductor spasmodic dysphonia.

    In healthy subjects (HS), transcranial magnetic stimulation (TMS) applied during 'linguistic' tasks discloses excitability changes in the dominant hemisphere primary motor cortex (M1). We investigated 'linguistic' task-related cortical excitability modulation in patients with adductor-type spasmodic dysphonia (ASD), a speech-related focal dystonia. We studied 10 ASD patients and 10 HS. Speech examination included voice cepstral analysis. We investigated the dominant/non-dominant M1 excitability at baseline, during 'linguistic' (reading aloud/silent reading/producing simple phonation) and 'non-linguistic' tasks (looking at non-letter strings/producing oral movements). Motor evoked potentials (MEPs) were recorded from the contralateral hand muscles. We measured the cortical silent period (CSP) length and tested MEPs in HS and patients performing the 'linguistic' tasks with different voice intensities. We also examined MEPs in HS and ASD during hand-related 'action-verb' observation. Patients were studied under and not-under botulinum neurotoxin-type A (BoNT-A). In HS, TMS over the dominant M1 elicited larger MEPs during 'reading aloud' than during the other 'linguistic'/'non-linguistic' tasks. Conversely, in ASD, TMS over the dominant M1 elicited increased-amplitude MEPs during 'reading aloud' and 'syllabic phonation' tasks. CSP length was shorter in ASD than in HS and remained unchanged in both groups performing 'linguistic'/'non-linguistic' tasks. In HS and ASD, 'linguistic' task-related excitability changes were present regardless of the different voice intensities. During hand-related 'action-verb' observation, MEPs decreased in HS, whereas in ASD they increased. In ASD, BoNT-A improved speech, as demonstrated by cepstral analysis and restored the TMS abnormalities. ASD reflects dominant hemisphere excitability changes related to 'linguistic' tasks; BoNT-A returns these excitability changes to normal.

    Full Text Available Introduction. This study prospectively evaluates and compares the treatment efficacy of botulinum toxin injection under electromyography guidance (EMG group and percutaneous botulinum toxin injection under flexible fiberscopic guidance (fiberscopy group. Methods. Thirty patients with adductor spasmodic dysphonia (ADSD, who had never received treatment, were randomly allocated into EMG- or fiberscopy-guided botulinum toxin injections between March 2008 and February 2010. We assessed acoustic and aerodynamic voice parameters, and the voice handicap index (VHI before injection and at 1, 3, and 6 months after injection. Results. The mean total dosage of botulinum toxin was similar for both groups: 1.7 ± 0.5 U for the EMG group and 1.8 ± 0.4 U for the fiberscopy group (P>0.05. There were no significant differences in outcomes between the two groups in either the duration of effectiveness or complications such as breathy voice and aspiration. Conclusion. Botulinum toxin injection under fiberscopic guidance is a viable alternative to EMG-guided botulinum toxin injection for the treatment of adductor spasmodic dysphonia when EMG equipment is unavailable.

    Full Text Available BACKGROUND Spasmodic dysphonia is a neurological disorder, which can give the voice a strained quality. There is currently no cure for spasmodic dysphonia. The most common treatment for spasmodic dysphonia is the injection of botulinum toxin. METHODS Botulinum toxin A injection was performed in 10 patients with adductor spasmodic dysphonia. Voice handicap index scoring and voice analysis was done pre- and post-injection. Fundamental frequency, standard deviation of fundamental frequency, jitter, shimmer, mean phonation time and voice noise energy was studied in voice analysis. These voice parameters were measured from sustained phonation of vowel /a/. RESULTS Results of study indicated, a Spasmodic dysphonia patients had high mean values for voice handicap index score and all voice parameters. b All parameters were reduced significantly post botulinum therapy, but remained higher than their normal value. c All voice parameters except jitter showed strong positive correlation with voice handicap index in all domains. Jitter showed moderate positive correlation with total score, physical and emotional domain and strong positive correlation with functional domain. CONCLUSION Botulinum toxin A injection improves voice in cases of spasmodic dysphonia, significantly still post procedure voice does not return to normal.

    Since it was first described in 1871, spasmodic (spastic) dysphonia has been considered a disease of psychogenic origin. Unsupported theories of possible organic etiology have appeared sporadically in the literature. In 1976 sectioning of the recurrent laryngeal nerve for patients with this disease was reported with resultant improvement in voice production. This was attempted because the spasmodic dysphonic has, in effect, already compensated vocal cords bilaterally. It was reasoned, therefore, that if one of these was paralyzed the patient would immediately be converted to a state approximating that of well-compensated unilateral vocal cord paralysis which situation, as is well known, usually carries with it a fairly good voice. A controlled study to evaluate the efficacy of this surgical approach has been undertaken at the Cleveland Clinic during the past year. In an attempt to elucidate the possible organic etiology of spasmodic dysphonia, a section of nerve was removed in every case and examined by both light and electron microscopy. Special stains for myelin were also used on the light microscopy specimens. Demyelinization has been found in most of the cases examined by electron microscopy. Possible correlation between this disease entity and other cranial nerve syndromes of unknown etiology is noted. Such conditions as trigeminal neuralgia, glossopharyngeal neuralgia, belpharospasm, hemifacial spasm, and even possibly Bell's palsy may exhibit a similar etiology.

    Full Text Available Background/Aim. Spasmodic dysphonia (DS is a disabling speech disturbance appearing as the consequence of dystonic vocal folds contraction. Its intermittent appearance in the laryngeal muscles causes vocal function discontinuation. The quality of life of these patients is significantly disturbed. Surgical and a medical therapy appear to be inadequate and unsuccessful ones of no steady improvement. It is the botulinum toxin therapy that proved to be highly efficacious one, with the established improvement in 80−100% of patients. The aim of our study was to evaluate the efficacy of botulinum toxin therapy in patients with SD and to show our preliminary results. Methods. The study included 10 patients with adductor spasmodic dysphonia. After diagnostic procedures, botulinum toxin was applied either in one or both vocal folds, in doses of 12−16 units each. In our study we applied indirect technique originally developed by Hočevar and Pirtošek. Perceptive voice and speech analysis was performed prior to and after the instillation of botuline toxin as per structured Scale of pathological characteristics of voice and speech appearing in the spasmodic dysphonia. Results. The majority of our patients experienced both subjective improvement and the improvement in the terms of the quality of life, Voice Henolicap Index − (VHI that was rated as rather significant one (t = 3.562; p = 0.006. Conclusion. Regardless unquestionable improvement of definite phonation, further function restitution requires individual vocal therapy and psychotherapy. Vocal therapy includes structural vocal techniques which reduce degree of vocal tension and rapid changes in the power and the height of voice. Further investigations are necessary for the scope of the definition of a standardized therapeutically procedure for spasmodic dysphonia treatment which comprises multidisciplinary approach in diagnosis, therapy and treatment efficacy evaluation.

    Spasmodic dysphonia is a primary focal dystonia characterized by involuntary spasms in the laryngeal muscles during speech production. The pathophysiology of spasmodic dysphonia is thought to involve structural and functional abnormalities in the basal ganglia–thalamo-cortical circuitry; however, neurochemical correlates underpinning these abnormalities as well as their relations to spasmodic dysphonia symptoms remain unknown.

    Locus of Control (LoC) refers to an individuals' perception of whether they are in control of life events. Health Locus of Control refers to whether someone feels they have influence over their health. Health Locus of Control has not been studied in any depth in voice-disordered patients. The objective of this study was to examine Health Locus of Control in three patient groups: (1) Spasmodic Dysphonia, (2) Functional Dysphonia and (3) a nondysphonic group with Nonlaryngeal Dystonia. LoC was measured and compared in a total of 57 patients using the Multidimensional Health Locus of Control Scales (diagnostic specific) Form C. Internal, Chance, and Powerful others LoC were measured and comparisons were made using one-way analysis of variance. Contrary to expectations Internal LoC was found to be significantly higher in the Functional Dysphonia group when compared to the other two groups. There was no significant difference between the groups in Chance or Powerful others LoC. The two organic groups, Spasmodic Dysphonia and Nonlaryngeal Dystonia, were more alike in Internal Health Locus of Control than the Functional Dysphonia group. The diagnostic nature of the groups was reflected in their LoC scores rather than their voice loss. These results contribute to the debate about the etiology of Spasmodic Dysphonia and will be of interest to those involved in the psychology of voice and those managing voice-disordered patients.

    Chemodenervation by injection of botulinum toxin type A into the vocal fold(s) has become the preferred treatment for patients with adductor spasmodic dysphonia. Injection may be done either perorally or transcutaneously; each method has its advocates and advantages. The authors have used the transcutaneous transcricothyroid membrane route exclusively with satisfactory results in more than 50 patients. Temporary breathliness and aspiration are common. The preferred injection site should be as close as possible to the motor end plates of the affected muscle. The thyroarytenoid muscle end plates are distributed throughout the muscle, whereas in the lateral cricoarytenoid muscle they are located in band in the center of the muscle. The transcutaneous injection site is below and posterior to the midpoint of the vibrating vocal fold as visualized by indirect laryngoscopy. The proximity of this site to the lateral cricoarytenoid muscle suggests that postinjection breathiness and aspiration may be related to spread of botulinum toxin type A to the lateral cricoarytenoid muscle. However, it is likely that thyroarytenoid muscle paresis is mainly responsible for this side effect and that the rapid clearing of the breathy dysphonia in the face of prolonged relief of spasmodic dysphonia symptoms suggests the action of an adaptive neural response, such as axonal sprouting. Further research of this subject is warranted. PMID:8196438

    Full Text Available Introduction: Spasmodic dysphonia (SD is a problem that affects speech and vocalization, one of the most devastating disorders of oral communication. It is characterized by vocal quality tensaestrangulada, harshly and / or interspersed with abrupt vocal attack and a great tension in the vocal tract. The etiology of spasmodic dysphonia is unclear. Some authors point to psychogenic causes, neurological or even unknown. Objective: To assess the prevalence of muscular dystonias and other neurological symptoms in patients with ED. Method: A retrospective study of 10 cases with diagnosis of ED for symptoms and neurological disorders associated. Results: There was a significant predominance of the disease in females (9:1. The average age of onset of symptoms was 32 years, ranging between 14 and 60 years. The mean disease duration was 10 years. Among the patients, 87.5% had a diagnosis of disorders of movement made by a neurologist, including orofacial dystonias (50%, essential tremor (50% and spastic paraparesis (12%. Conclusion: The presence of movement disorders followed almost all cases of spasmodic dysphonia. More studies are needed to clarify the pathophysiological basis of disease.

    The etiology of spasmodic dysphonia (SD) is still unknown. In the present study, cortical function of a 59-year-old male patient with adductor type SD was examined during phonation with positron emission tomography (PET). Magnetic resonance imaging showed no organic abnormality in the brain. However, PET showed remarkable activities during phonation in the left motor cortex, Broca's area, the cerebellum, and the auditory cortices, whereas the supplementary motor area (SMA) was not activated. The SMA is known to function for motor planning and programming and is usually activated in normal phonation. Several previous reports have shown that the damage of the SMA caused a severe disturbance of voluntary vocalization. In the present case, it was suggested that the functional deficit of the SMA might be related to SD.

  9. Psychogenic spasmodic dysphonia: a case study with expert opinions.

    Science.gov (United States)

    Sapir, S

    1995-09-01

    Spasmodic (spastic) dysphonia (SD) is considered by some to be a neurologic syndrome and by others a symptom complex of multiple etiologies, neurologic and psychogenic. A case of a 26-year-old female psychiatric nurse with psychogenic SD (PSD) is presented. The dysphonia was alleviated within one session of voice therapy. Psychogenic etiology was established by the author, based on three diagnostic criteria--symptom incongruity, symptom reversibility, and symptom psychogenicity. Seven nationally recognized voice experts listened to audio-recorded samples of the patient's pre- and posttherapy voice during conversational speech. The experts agreed that the dysphonia was psychogenic and characterized it as staccato-like speech, effortful phonation, and interrupted flow of speech; six characterized it with intermittent voice arrests (voice stoppages); five with hoarse-harsh voice; and four with waxing and waning, strained-strangled phonation. These are often described as salient features of SD. Nevertheless, the experts disagreed among themselves as to whether the dysphonia was characteristic of SD and should be labeled as such. The author argues that as long as the voice characteristics and pathophysiologic findings that constitute SD are not well delineated, and as long as the diagnosis of SD is based on symptoms alone, patients with psychogenic or poorly understood voice disorders are likely to be misdiagnosed with organic (neurologic) SD and thus subjected to undue medical treatment. The author also argues that the debate over the etiology of SD can be resolved if SD is considered a neurologic syndrome, PSD a nonorganic phonatory disorder that mimics the syndrome, and if the voice symptoms and pathophysiologic characteristics of SD are well defined and agreed on.

    Chemodenervation with botulinum toxin (BoNT) has been effective and well tolerated for all types of dystonia for >30 years. We reviewed outcomes of our patients treated with BoNT serotype A (BoNT-A) for spasmodic dysphonia (SD) who became secondarily nonresponsive. We found that 8 of 1400 patients became nonresponsive to BoNT-A (0.57%), which is lower than the secondary nonresponse rate in other dystonias. After a cessation period, 4 of our patients resumed BoNT-A injections, and recurrence of immunoresistance was not seen in any of them. When compared with patients with other dystonias, patients with SD receive extremely low doses of BoNT. Small antigen challenge may explain the lower rate of immunoresistance and long-lasting efficacy after BoNT-A is restarted among secondary nonresponsive patients with SD. PMID:27143711

    Spasmodic dysphonia (SD) is a focal dystonia of laryngeal muscles seriously impairing quality of voice. Adductor SD (ADSD) is the most common presentation of this disorder that can be identified by specialized phoniatricians and neurologists firstly on a clinical evaluation and then confirmed by videolaryngoscopy (VL). Botulinum toxin (BTX) injection with electromyographic guidance in muscles around vocal cords is the most effective treatment. Voice Handicap Index (VHI) questionnaire is the main tool to assess dysphonia and response to treatment. Objective of this study is to perform VL and voice spectrography (VS) to confirm the efficacy of BTX injections over time. 13 patients with ADSD were studied with VHI, VL and VS before and after 4 consecutive treatment with onobotulinumtoxin-A. For each treatment vocal improvement was proved by a significant reduction of VHI score and increase of maximum time phonation and harmonic-to-noise ratio while VL showed the absence of spasm in most of patients. No change of the response to BTX was found between injections. This study supports the efficacy of the treatment of SD with BTX with objective measurements and suggests that the efficacy of recurring treatments is stable over time. PMID:25966878

    2012-07-01

    Spasmodic torticollis or cervical dystonia (CD) is the most common form of focal dystonia and is characterized by sustained abnormal muscle contractions in the head and neck area resulting in abnormal positioning or posturing of the head. The dystonic muscle spasms associated with spasmodic torticollis may affect any combination of neck muscles. Three cases are reported of spasmodic torticollis that were treated by a dental appliance with individual varying occlusal heights to open the maxillomandibular vertical dimension. Upon increasing the vertical dimension of occlusion, there was a slowing and/or discontinuance of the symptoms of cervical dystonia. The proposed hypothesis for this reversal is that there may be neuritis of the auriculotemporal branch of the trigeminal nerve, which has direct input into the reticular formation (RF), and it may activate the cells of the pontine region of the RF known for the control and deviation of head posture. There is growing clinical evidence that temporomandibular joint (TMJ) dysfunction may be a factor in this neurological and painful disorder when it coexists. PMID:22916671

    Dysphonia is a frequent reason for consultation in children. Most of the time, this presentation is the consequence of a vocal abuse, however, the physician has to be aware that an organic lesion, such as laryngeal papillomatosis can exist and so perform a flexible laryngoscopy. In case of laryngeal papillomatosis, surgery and several medical treatments will be proposed for a long time. In other cases, speech therapy, sometimes associated with surgery, will be performed.

    Full Text Available OBJECTIVE: To propose and test the applicability of a dysphonia risk screening protocol with score calculation in individuals with and without dysphonia. METHOD: This descriptive cross-sectional study included 365 individuals (41 children, 142 adult women, 91 adult men and 91 seniors divided into a dysphonic group and a non-dysphonic group. The protocol consisted of 18 questions and a score was calculated using a 10-cm visual analog scale. The measured value on the visual analog scale was added to the overall score, along with other partial scores. Speech samples allowed for analysis/assessment of the overall degree of vocal deviation and initial definition of the respective groups and after six months, the separation of the groups was confirmed using an acoustic analysis. RESULTS: The mean total scores were different between the groups in all samples. Values ranged between 37.0 and 57.85 in the dysphonic group and between 12.95 and 19.28 in the non-dysphonic group, with overall means of 46.09 and 15.55, respectively. High sensitivity and specificity were demonstrated when discriminating between the groups with the following cut-off points: 22.50 (children, 29.25 (adult women, 22.75 (adult men, and 27.10 (seniors. CONCLUSION: The protocol demonstrated high sensitivity and specificity in differentiating groups of individuals with and without dysphonia in different sample groups and is thus an effective instrument for use in voice clinics.

    2002-01-01

    An in-season adductor muscle strain may be debilitating for the athlete. Furthermore, an adductor strain that is treated improperly could become chronic and career threatening. Any one of the six muscles of the adductor group could be involved. The degree of injury can range from a minor strain (Grade I), where minimal playing time is lost, to a severe strain (Grade III) in which there is complete loss of muscle function. Ice hockey and soccer players seem particularly susceptible to adductor muscle strains. In professional ice hockey players throughout the world, approximately 10% of all injuries are groin strains. These injuries, which have been linked to hip muscle weakness, previous injuries to that area, preseason practice sessions and level of experience, may be preventable if such risk factors can be addressed before each season. Hip-strengthening exercises were shown to be an effective method of reducing the incidence of adductor strains in one closely followed National Hockey League ice hockey team. Despite the identification of risk factors and strengthening intervention for ice hockey players, adductor strains continue to occur throughout sport. Clinicians feel an active training programme, along with completely restoring the strength of the adductor muscle group, is the key to successful rehabilitation. Surgical intervention is available if nonoperative treatment fails for 6 months or longer. Adductor release and tenotomy was reported to have limited success in athletes. PMID:11929360

    Full Text Available Introduction. Hyperkinetic (hyperfunctional dysphonia is a common pathology. The disorder is often found in vocal professionals faced with high vocal requirements. Objective. The objective of this study was to evaluate the effects of vocal therapy on voice condition characterized by hyperkinetic dysphonia with prenodular lesions and soft nodules. Methods. The study included 100 adult patients and 27 children aged 4-16 years with prenodular lesions and soft nodules. A subjective acoustic analysis using the GIRBAS scale was performed prior to and after vocal therapy. Twenty adult patients and 10 children underwent objective acoustic analysis including several acoustic parameters. Pathological vocal qualities (hoarse, harsh and breathy voice were also obtained by computer analysis. Results. The subjective acoustic analysis revealed a significant (p<0.01 reduction in all dysphonia parameters after vocal treatment in adults and children. After treatment, all levels of dysphonia were lowered in 85% (85/100 of adult patients and 29% (29/100 had a normal voice. Before vocal therapy 9 children had severe, 13 had moderate and 8 slight dysphonia. After vocal therapy only 1 child had severe dysphonia, 7 had moderate, 10 had slight levels of dysphonia and 9 were without voice disorder. The objective acoustic analysis in adults revealed a significant improvement (p≤0.025 in all dysphonia parameters except SD F0 and jitter %. In children, the acoustic parameters SD F0, jitter % and NNE (normal noise energy were significantly improved (p=0.003-0.03. Pathological voice qualities were also improved in adults and children (p<0.05. Conclusion. Vocal therapy effectively improves the voice in hyperkinetic dysphonia with prenodular lesions and soft nodules in both adults and children, affecting diverse acoustic parameters.

    Functional dysphonia is a voice impairment without any organic lesion of the phonating system. It may be classified into two categories: functional dysphonia itself where no lesions are found and functional laryngopathies where vocal cord lesions may be attributed to vocal abuse or misuse. The clinical evaluation of a dysphonic patient is performed in three steps: history taking, vocal evaluation, and examination. History taking helps the diagnosis and may be considered also as a therapeutic procedure. Vocal evaluation is oriented toward the voice itself and how it is produced. Then an ENT examination is performed with special attention to the larynx. In functional dysphonia, usually, everything looks normal but there may be signs of inflammation, hyperkinetism, hypokinetism, excessive laryngeal movements, etc. Functional laryngopathies include vocal nodules, laryngitis, polyps, and contact ulcer.

    Hoarseness is the leading symptom of dysphonia among children and adolescents. The incidence is evaluated internationally to be 6-25%. In an overview the hereditary and acquired organic and functional causes including secondary organic lesions of the vocal folds, the pathomechanisms and the symptoms typical for this age group are presented. In clinical routine, symptoms of dysphonia in children and adolescents should be consciously looked for and any long-term hoarseness should be examined by specialized physicians, even in this age group, using methods suitable to the age group and the developmental stage. When the appropriate indications are present all therapeutic options currently available should be taken into consideration. Furthermore, this paper provides information for the parents concerning the imminent phoniatric examination.

    Full Text Available Inhibition of vascular endothelial growth factor (VEGF signaling, an initiator of tumor angiogenesis, inhibits tumor growth and invasion. Bevacizumab, a monoclonal antibody to VEGF, in common use as an adjunct to standard chemotherapy like irinotecan in advanced colorectal cancer, also affects the normal (nontumor vasculature. Dysphonia or voice changes have been anecdotally reported in patients that have been exposed to antiangiogenics. In this case report, we present an occurrence of severe dysphonia in a 60-year-old male with metastatic colorectal cancer after reintroduction of irinotecan and bevacizumab. To our knowledge, this is the first case of dysphonia associated with bevacizumab rechallenge.

    Single-voxel proton magnetic resonance spectroscopy ({sup 1}H-MRS), localised to the basal ganglia, was used to determine changes in metabolite levels in idiopathic spasmodic torticollis (IST). We examined nine patients and 13 healthy subjects. The mean values ({+-} SD) of peak area ratios were: IST: N-acetyl-aspartate (NAA)/choline-containing compounds (Cho) 1.79 {+-} 0.39, NAA/creatine and phosphocreatine compounds (Cr) 1.61 {+-} 0.38, Cho/Cr 0.91 {+-} 0.19; controls: NAA/Cho 2.07 {+-} 0.35, NAA/Cr 1.82 {+-} 0.31, Cho/Cr 0.89 {+-} 0.12. Statistical analysis showed that NAA/Cho and NAA/Cr were significantly lower in patients than in controls (P = 0.0304 and 0.0431, respectively). These results indicate a reduction in NAA, and suggest striatal involvement in the pathogenesis IST. (orig.)

    Teachers are professionals with high prevalence of dysphonia, whose main risk factors are the large work hours in classrooms with the presence of background noise. The purpose of the study was to calculate the phonation time and the cycle dose of teachers with dysphonia and teachers without voice disorders during the class. There were two groups analyzed: five teachers with functional dysphonia were the first group and five teachers without voice disorders were the second group. For the data was used the VoxLog® dosimeter and the parameters were: intensity; fundamental frequency; phonation time and cycle dose. The statistical analysis used ANOVA, Student's T-test, and Kruskal-Wallis test. Dysphonic teachers showed major values of phonation time and cycle dose compared with teachers without voice disorders. The dysphonia is related to extended period of speech time and greater exposure of the tissue of the vocal fold to phonotrauma. PMID:27191884

    Acute laryngitis is most often caused by viral illnesses through direct inflammation of the vocal cords or from irritation due to postnasal drainage. Bacterial infections, such as acute epiglottitis, also can cause dysphonia but typically have other systemic symptoms as well as respiratory distress. Chronic laryngitis is characterized by symptoms lasting more than 3 weeks. Chronic vocal cord issues can be related to overuse or stress on the vocal cords resulting in nodules or polyps. Individuals in certain occupations, such as singers, school teachers, and chemical workers, are at greater risk of chronic laryngitis. The diagnostic approach to chronic laryngitis should include visualization of the vocal cords to rule out potential malignant lesions. For acute and chronic overuse symptoms, the best treatment is vocal rest. The use of antibiotics or decongestants should be discouraged.

  17. Hip adductors' strength, flexibility, and injury risk.

    2009-08-01

    The hip adductor muscle group plays an important role in both movement and stability at the hip joint in many athletic pursuits. Injury to this muscle group has been reported in a number of sports, among them, ice hockey, soccer, Australian football, and swimming. The identification of muscle characteristics that predispose a muscle to injury is an important step in developing conditioning programs to reduce injury risk. Muscle strength and range of motion are 2 parameters that may influence injury risk. The aim of this review was to examine the relationship between hip adductors' strength, flexibility, and injury risk. Strength testing has involved isokinetic or hand-held dynamometry. Flexibility has usually been assessed by goniometry during maximal hip abduction. An association has been reported between adductor strength deficits and injury for ice hockey players. Low adductor flexibility has also been identified as a risk factor for injury in soccer players. An intervention program that strengthened the hip adductors had some success in reducing injury risk for ice hockey players. There is some low- to moderate-level evidence from cohort studies to suggest that flexibility and strength are related to injury risk in particular sports and that an intervention program may be effective in reducing injury risk. Higher level evidence from randomized controlled trials is required to firmly establish the link between hip adductor flexibility, strength, and injury. PMID:19620912

    Full Text Available Infections of the deep spaces of the neck, like the prevertebral abscess, can present with catastrophic consequences due to compromise of air and food passages. The most common causes of the prevertebral abscess in orthopedic practice are tuberculosis of spine, retropharyngeal abscess, infections secondary to foreign body impalement and injury. Early recognition of these conditions is necessary to avert fatal complications. We report a case of a 50-year-old gentleman who presented with symptoms of dysphagia and dysphonia with altered sensorium of 4 days duration. He was diagnosed with septicemia, diabetic ketoacidosis, and an upper motor neuron type of quadriparesis. There was diffuse swelling over the anterior aspect of the neck with magnetic resonance imaging study suggesting a prevertebral abscess with septic discitis of cervical 5 and 6 vertebras. The case is presented along with the literature review discussed as an unusual cause of septic discitis due to Klebsiella manifesting as dysphonia and dysphagia.

    Spastic dysphonia is a severe voice disorder ordinarily described as psychogenic. Organic-neurologic changes secondary to central or peripheral nervous system involvement have also been postulated and led recently to the surgical treatment of spastic dysphonia by unilateral section of the recurrent laryngeal nerve (RLN). This study reports the histologic findings from these resections of the RLN from patients with an average 9.5 years duration of spastic dysphonia. Thirty percent of the RLNs examined demonstrated significant abnormalities as compared to age-matched controls. Although no reactive changes were noted by light microscopy, groups of fibers which did not stain for myelin or axons were found in RLNs from patients with spastic dysphonia. A preliminary ultrastructural study of these areas in one RLN revealed sheets of unmyelinated axons. These findings suggest an organic basis for spastic dysphonia at least in some patients.

    For over 100 years it has been universally assumed in the literature that spastic dysphonia is a functional or psychoneurotic voice disorder. In the last few years, new data have accumulated that support the concept that spastic dysphonia is caused by an organic, rather than a functional, abnormality. Histologic examination of segments of the recurrent laryngeal nerve removed from patients with spastic dysphonia has revealed myelin abnormalities in 30% of the nerves examined. Neurologic examination indicated brain stem or basal ganglia disturbances in some patients who had no apparent nerve disease.

    This study aims to compare the isokinetic profile of hip abductor and adductor muscle groups between soccer players suffering from chronic adductor-related groin pain (ARGP), soccer players without ARGP and healthy volunteers from general population. Study included 36 male professional soccer players, who were randomly selected and followed-up over two years. Of the 21 soccer players eligible to participate in the study, 9 players went on to develop chronic ARGP and 12 players did not. Ten healthy male volunteers were randomly selected from the general population as a control group. Comparison between the abductor and adductor muscle peak torques for players with and without chronic ARGP found a statistically significant difference on the dominant and non-dominant sides (p muscle significantly stronger than the adductor muscle. In the group of healthy volunteers, the adductor muscle groups were significantly stronger than the abductor muscle groups on both dominant and non-dominant sides (p adductor torque ratios were significantly higher on the affected side (p = .008). The adductor muscle strength was also significantly decreased on the affected side. This imbalance appears to be a risk factor for adductor-related groin injury. Therefore, restoring the correct relationship between these two agonist and antagonist hip muscles may be an important preventative measure that should be a primary concern of training and rehabilitation programmes.

    The authors evaluated 11 surgically-treated patients with spastic dysphonia, a phonation disorder of unclear etiology. The results indicate that the illness does not appear to be a somatoform disorder, but that stress may play a role in its expression, and that there may be secondary depression and anxiety. The experience of spastic dysphonics suggests that psychiatric treatments may be inappropriately applied to an illness without clear organic etiology, whereas, conversely, a proper psychiatric role may be rejected when effective medical or surgical treatment is available. The authors recommend that psychiatrists evaluating patients with illnesses of unclear etiology should be cautious in making a primary psychiatric diagnosis unless DSM-III criteria are met.

It is a multifaceted voice disorder. There is no consensus with regard to its definition and inclusion criteria for diagnosis. FD has many predisposing and precipitating factors, which may include genetic susceptibility, psychological traits, and the vocal behavior itself. The assessment of voice disorders should be multidimensional. In addition to the clinical examination, auditory-perceptual, acoustic, and self-assessment analyses are very important. Self-assessment was introduced in the field of voice 25 years ago and has produced a major impact in the clinical and scientific scenario. The choice of treatment for FD is vocal rehabilitation by means of direct therapy; however, compliance has been an issue, except for cases of functional aphonia or when an intensive training is administered. Nevertheless, there are currently no controlled studies that have explored the different options of treatment regimens for these patients. Strategies to improve patient outcome involve proper multidisciplinary diagnosis in order to exclude neurological and psychiatric disorders, careful voice documentation with quantitative measurement and qualitative description of the vocal deviation for comparison after treatment, acoustic evaluation to gather data on the mechanism involved in voice production, self-assessment questionnaires to map the impact of the voice problem on the basis of the patient's perspective, referral to psychological evaluation in cases of suspected clinical anxiety and/or depression, identification of dysfunctional coping strategies, self-regulation data to assist patients with their vocal load, and direct and intensive vocal rehabilitation to reduce psychological resistance and to reassure patient's recovery.

    Non organic dysphonia or functional voice disorders are the consequence of a vocal misuse or overuse with inefficient oral communication. Any stage of voice production can be altered. A review of physiopathological, aerodynamic and biomechanical mechanisms will help to understand the onset of dysphonia. Organic lesions as a consequence of functional voice disorders are frequent but the link is not easy to establish. It is important to look for various physiologic, anatomic, environmental, behavioural and infectious factors that could induce or aggravate non organic dysphonia, as they can benefit from specific treatment. A thorough functional and organic assessment is the first step of the rehabilitation process, taking into account the patient's expectations about his voice handicap.

    The International Classification of Diseases, 10th. revision (ICD-10) in the category F45 defines the somatoform disorder as a mental disease characterized by the reiterative presentation of somatic symptoms in absence of an organic disease, or the somatic pathology being insufficient to explain the intensity of the symptoms as well as the discomfort and preoccupation of the patient. Fifteen female teachers with functional dysphonia were studied by means of a semistructured interview and psychometric evaluations. Considering dysphonia as the principal symptom, the most frequent diagnosis, in accordance with ICD-10 was "Other somatoform disorder" (F-45.8)(9/15). Five patients were diagnosed as motor dissociative disorder (F-44.4). All the patients had some abnormality of personality (5 with personality disorder and 10 with exacerbation of personality traits). The criteria of ICD-10 to classify the functional dysphonia as Somatoform disorder are discussed. It is suggested that certain personality traits are facilitators for somatization.

A 35-year-old man was diagnosed with pneumonia and was recommended ciprofloxacin 500 mg iv twice a day for 7 days. Three days after receiving the initial dose, he developed discomfort in his left medial thigh, and pain and swelling in the same area followed ten days later. He consulted us when he noted a palpable mass on the medial side of his left thigh, and MRI study revealed adductor longus tendon rupture. There was no obvious underlying disease or other factor causing fragility of his adductor longus tendon. We review the pathophysiological mechanisms leading to fluoroquinolone-related tendon rupture as well as the risk factors and discuss proper management.

Pathological changes in the larynx may have organic or functional character which require different methods of treatment and rehabilitation. Visualization of vibrations of the vocal folds is an essential condition for an appropriate assessment of the causes of dysphonia. [b]objective[/b]. The purpose of the study is assessment of the usefulness of a high-speed imaging (HSI system in the diagnosis of functional and organic dysphonia of occupational character, compared with digital kymography (DKG and digital stroboscopy (DS with a high resolution module. [b]material and methods[/b]. The study group consisted of 64 patients with voice quality disorders with features of occupational dysphonia. The control group consisted of 15 patients with euphonic voice. Analysis of the voice quality parameters during phonation of the ‘e’ vowel was performed using HSI, DKG and stroboscopy of high resolution, by means of a digital HS camera (HRES Endocam, Richard Wolf GmbH, Knittlingen, Germany. Vocal folds vibrations were registered at the rate of 4,000 frames per second. [b]results[/b]. HSI is the most reliable diagnostic tool giving the possibility of an analysis of the true vibrations of the vocal folds. It also enables an observation of the aperiodicity of vibrations of the vocal folds, while DS with high resolution allows diagnosis of the periodicity of the vibrations. [b]conclusions[/b]. HSI is particularly useful in the diagnosis of neurologically-based pathology of the voice (paralytic dysphonia and organic dysphonia. The quickest method of diagnosing the phonatory paresis of the glottis is DKG. The advantage of both HSI and DKG is the non-invasiveness of examinations; however, their limitations are time-consuming and the high cost of equipment.

    Full Text Available This study evaluated the measurement of adductor pollicis muscle thickness as a parameter for the assessment of nutritional status in patients admitted to a University Hospital in Campo Grande, Mato Grosso do Sul State. This is a prospective cross-sectional study with 64 adults and elderly patients. We evaluated the percentage of weight loss based on the usual weight, arm circumference, triceps skinfold thickness, arm muscle circumference, laboratory parameters and measurement of adductor pollicis muscle thickness. The measurements were performed only once, in the first 72 hours of hospitalization. Data were analyzed using statistical software BioEstat 5.0, with a significance level of 0.05. The average thickness of the adductor pollicis muscle was 17.5 + 5.3 mm. We found a significant negative association of muscle with age. There was a significant association between the measure of muscle and parameters such as body mass index, arm circumference, arm muscle circumference, albumin and nutritional status assessed by physical examination. The adductor pollicis muscle allows easy measurement, direct assessment, fast results, low cost and good correlation with anthropometric parameters. However, further studies should be conducted to validate this new method.

    The study of 259 children in primary school revealed a prevalence of dysphonia of 10%, often undiagnosed, untreated or considered as benign. It would seem desirable to draw attention to this symptom, which may be an indication of organic pathology or of psychological problems, the early treatment of which may avoid later sequelae. It is sometimes necessary to allow a period for reflection in order to gain the cooperation of the child and his parents.

    Full Text Available Tuberculosis is still the most frequent granulomatous laryngeal disease. Absence of pathognomonic symptoms and change in clinical pattern frequently leads to misdiagnosis and delayed treatment. Hoarseness is the commonest symptom of laryngeal tuberculosis and constitutional symptoms are usually rare. However dysphonia can be caused by many other more common conditions. Hoarseness can be a symptom of organic (nodules and polyps of vocal folds, tumors, vocal fold paresis or functional (functional dysphonia, laryngeal conversion disorder, paradoxical vocal folds motion conditions. Rarely systemic diseases as amyloidosis, sarcoidosis, Wegener’s granulomatosis or tuberculosis can cause vocal dysfunction too. That is why laryngeal tuberculosis is often forgotten in case of persistent hoarseness. In this article, we present a case of a young previously healthy woman, complaining of persistent hoarseness with no other leading symptoms. Though endoscopic image suggested a malignancy, histology showed granulomatous lesion. Detailed examination revealed laryngeal and pulmonary tuberculosis resistant to rifampicin. Conclusion: Dysphonia can be the only one symptom of laryngeal tuberculosis. The disease should be taken into consideration when a patient complains of persistent hoarseness in order to avoid delays in treatment and spread of infection.

  17. Treatment of spastic dysphonia by recurrent laryngeal nerve section.

    Science.gov (United States)

    Barton, R T

    1979-02-01

    The problem of management of patients with spastic dysphonia has been complicated by a general resistance to speech therapy, psychotherapy, hypnotherapy, and drug therapy. Dedo introduced the concept of recurrent laryngeal nerve section in an attempt to eliminate the hyperfunction and excessive adduction of the vocal folds. Eleven patients were treated by RLN section with satisfactory results in 8 and some improvement in the other 3. The operation was found to be generally uncomplicated and required on average 4 days of hospitalization. Dedo's theory that spastic dysphonia is caused by a neurotropic viral-induced proprioceptive nerve deficit represents a new search for organic cause. His most recent report of finding unmyelinated fibres in one-third of the resected recurrent laryngeal nerves is of questionable significance. The evidence of deep emotional conflict and/or compulsive life-style is found in the majority of the patients, but the syndrome is not typical of an hysterical or conversion neurosis. Regardless of etiologic theory, RLN section is an effective treatment in selected, long-standing, and resistant instances of spastic dysphonia.

    2013-01-01

    The laryngeal adductor reflex (LAR) is an involuntary protective response to stimuli in the larynx. The superior laryngeal nerve (SLN) acts as the afferent limb and the recurrent laryngeal nerve (RLN) as the efferent limb of this reflex, which is modulated by the central nervous system. Perhaps the most clinically significant application of the LAR is its use in laryngopharyngeal (LP) sensory discrimination testing. Importantly, aberrations in the LAR may predict dysphagia or portend clinical...

  2. Scaling and Accommodation of Jaw Adductor Muscles in Canidae.

    Science.gov (United States)

    2016-07-01

    The masticatory apparatus amongst closely related carnivoran species raises intriguing questions about the interplay between allometry, function, and phylogeny in defining interspecific variations of cranial morphology. Here we describe the gross structure of the jaw adductor muscles of several species of canid, and then examine how the muscles are scaled across the range of body sizes, phylogenies, and trophic groups. We also consider how the muscles are accommodated on the skull, and how this is influenced by differences of endocranial size. Data were collected for a suite of morphological metrics, including body mass, endocranial volume, and muscle masses and we used geometric morphometric shape analysis to reveal associated form changes. We find that all jaw adductor muscles scale isometrically against body mass, regardless of phylogeny or trophic group, but that endocranial volume scales with negative allometry against body mass. These findings suggest that head shape is partly influenced by the need to house isometrically scaling muscles on a neurocranium scaling with negative allometry. Principal component analysis suggests that skull shape changes, such as the relatively wide zygomatic arches and large sagittal crests seen in species with higher body masses, allow the skull to accommodate a relative enlargement of the jaw adductors compared with the endocranium.

  13. Heat treatment of scallop adductor muscle using superheated steam.

    2007-08-01

    Scallop (Patinopecten yessoensis) adductor muscles were heated using superheated steam (150 and 200 degrees C), boiling (98 degrees C), and normal steaming (95 degrees C). The amounts of amino acids, water-soluble peptides, and nucleotides, expressed as extractive nitrogen in scallop products, are very important elements of quality and taste. After 15-min heating of scallop muscles with normal steaming and boiling, respective losses of 50% and 64% of the extractive nitrogen were observed. However, most extractive nitrogen (> 86%) remained in the scallop muscles treated with superheated steam at 150 and 200 degrees C. Protective effects of superheated steam against elution loss of nitrogen compounds were also observed in amino acid analyses of the heated products. The scallop-muscle surface temperature during treatment with superheated steam increased more quickly than that with normal steaming and boiling. The rapid water loss and the surface protein denaturation engendered formation of a 30-mum-thick film covering the surface, which prevented extractive nitrogen loss from internal tissues. Superheated steam treatment at 200 degrees C caused browning, surface shrinkage, and 47% weight loss. In marked contrast, the appearance and the weight loss of sample treated at 150 degrees C were almost the same as those of normal steaming and boiling-treated samples. These results suggested that superheated steaming at 150 degrees C is an optimal heat treatment of scallop adductor muscles.

    This study determined the magnitude of change in adductor strength after a competitive match in academy rugby union players and examined the relationship between locomotive demands of match-play and changes in postmatch adductor strength. A within-subject repeated measures design was used. Fourteen academy rugby union players (age, 17.4 ± 0.8 years; height, 182.7 ± 7.6 cm; body mass, 86.2 ± 11.6 kg) participated in the study. Each player performed 3 maximal adductor squeezes at 45° of hip flexion before and immediately, 24, 48, and 72 hours postmatch. Global positioning system was used to assess locomotive demands of match-play. Trivial decreases in adductor squeeze scores occurred immediately (-1.3 ± 2.5%; effect size [ES] = -0.11 ± 0.21; likely, 74%) and 24 hours after match (-0.7 ± 3%; ES = -0.06 ± 0.25; likely, 78%), whereas a small but substantial increase occurred at 48 hours (3.8 ± 1.9%; ES = 0.32 ± 0.16; likely, 89%) before reducing to trivial at 72 hours after match (3.1 ± 2.2%; ES = 0.26 ± 0.18; possibly, 72%). Large individual variation in adductor strength was observed at all time points. The relationship between changes in adductor strength and distance covered at sprinting speed (VO2max ≥ 81%) was large immediately postmatch (p = 0.056, r = -0.521), moderate at 24 hours (p = 0.094, r = -0.465), and very large at 48 hours postmatch (p = 0.005, r = -0.707). Players who cover greater distances sprinting may suffer greater adductor fatigue in the first 48 hours after competition. The assessment of adductor strength using the adductor squeeze test should be considered postmatch to identify players who may require additional rest before returning to field-based training.

    2014-01-01

    Full Text Available Osteomyelitis of the pubis symphysis is a rare condition. There have been various reports in the literature of inflammation and osteomyelitis as well as septic arthritis of pubic symphysis. However, due to the fact that these conditions are rare and that the usual presenting symptoms are very nonspecific, osteomyelitis of the pubic symphysis is often misdiagnosed, thus delaying definitive treatment. We present a case that to our knowledge is the first case in literature of osteomyelitis of the pubic symphysis in a 17-year-old boy with juvenile idiopathic arthritis (JIA, which was initially misdiagnosed and progressed to bilateral adductor abscesses. A high suspicion of such condition should be considered in a JIA patient who presents with symphysis or thigh pain.

    1994-11-01

    The passive extension of relaxed hip adductor muscles was measured in 20 normal children and 10 children (aged nine to 13 years) with cerebral palsy (CP) by a method that could distinguish between shortening of the muscle body and tendon. No muscle-body contracture occurred in the children with CP during treatment (physiotherapy plus moderate stretching on an apparatus for six hours a day); only the tendons were short. However, four children showed signs of muscle-body contracture after interrupting treatment for six to eight weeks. It is possible that muscle-body contracture can be prevented by non-surgical methods, although tendon shortening can, at present, only be treated surgically.

    Groin pain encompasses a number of conditions from the lower abdomen, inguinal region, proximal adductors, hip joint, upper anterior thigh and perineum. The complexity of the anatomy, the heterogeneous terminology and the overlapping symptoms of different conditions that may co-exist epitomise the challenges in diagnosis and treatment. Inguinal-related and adductor-related pain is the most common cause of groin pain and will be discussed in this article. PMID:27174069

    Full Text Available Introduction: Psychogenic dysphonia is a functional disorder with variable clinical manifestations. Objective: To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series. Methods: The study included 28 adult patients with psychogenic dysphonia, evaluated at a University hospital in the last ten years. Assessed variables included gender, age, occupation, vocal symptoms, vocal characteristics, and videolaryngostroboscopic findings. Results: 28 patients (26 women and 2 men were assessed. Their occupations included: housekeeper (n = 17, teacher (n = 4, salesclerk (n = 4, nurse (n = 1, retired (n = 1, and psychologist (n = 1. Sudden symptom onset was reported by 16 patients and progressive symptom onset was reported by 12; intermittent evolution was reported by 15; symptom duration longer than three months was reported by 21 patients. Videolaryngostroboscopy showed only functional disorders; no patient had structural lesions or changes in vocal fold mobility. Conversion aphonia, skeletal muscle tension, and intermittent voicing were the most frequent vocal emission manifestation forms. Conclusions: In this case series of patients with psychogenic dysphonia, the most frequent form of clinical presentation was conversion aphonia, followed by musculoskeletal tension and intermittent voicing. The clinical and vocal aspects of 28 patients with psychogenic dysphonia, as well as the particularities of each case, are discussed.

  6. [Application of acoustic analysis of the voice to diagnosis and treatment of functional dysphonia].

    2009-01-01

    Acoustic analysis of the voice was used to facilitate diagnosis and to objectively evaluate results of the treatment of psychogenic dysphonia (PD) in 20 women. The control group comprised 20 women showing no signs of laryngeal pathology. The following parameters were measure: jitter, shimmer, signal to noise ratio, and response in the voicing test. Other methods applied included laryngoscopy, videolaryngoscopy, and laryngostroboscopy. It was shown that hoarseness in patients with PD results from the disturbances of mechanisms controlling stability of phonation. This observation is confirmed by the results of the acoustic test. It is concluded that dysphonia confirmed in the acoustic test in the absence of organic changes in the larynx is caused by psychogenic factors. Acoustic analysis of the voice is indicated to objectively evaluate results of the treatment of psychogenic dysphonia.

    Phoniatric and acoustic examinations were carried out in a group of 30 patients with dysphonia, including 15 with organic type and 15 with functional type. A complex phoniatric assessment offered the possibility to differentiate between these two groups of pathological voices. This was achieved also on the basis of acoustic analysis of the voice by extracting characteristics such as: formant frequency, Fo and its range, percentage of noise in the analysed verbal text, mean and maximum values of jitter. The possibility of differential diagnosis of these two different types of dysphonia in acoustic studies was confirmed by clinical examinations. The acoustic studies presented can be regarded as a new approach to a fast and sufficiently precise method in the screening diagnostics of dysphonia conditioned by growth of the vocal fold mass.

    1996-01-01

    Full Text Available This paper deals with signs, symptoms and course in spasmodic torticollis (ST. Two hundred and fifty-six patients were included in the study, 59.3% women, 40.7% men. The mean age was 49.1 years. Rotating torticollis out-numbered latero- and antero-retrocollis. A family history of ST occurred in 3.1% of the total sample. First degree relatives were affected in 2.3%. Thirty-four per cent of the patients had additional dystonic symptoms. Most frequently these affected the upper extremities (13%, and less often the legs. Of the patients 19.1% had experienced a period of complete remission. The correlations between the severity of the signs and the neurological symptoms are surprisingly weak.

    The adductor canal is a conical or pyramid-shaped pathway that contains the femoral vessels, saphenous nerve and a varying amount of fibrous tissue. It is involved in adductor canal syndrome, a claudication syndrome involving young individuals. Our objective was to study modifications induced by aging on the connective tissue and to correlate them to the proposed pathophysiological mechanism. The bilateral adductor canals and femoral vessels of four adult and five fetal specimens were removed en bloc and analyzed. Sections 12 microm thick were obtained and the connective tissue studied with Sirius Red, Verhoeff, Weigert and Azo stains. Scanning electron microscopy (SEM) photomicrographs of the surfaces of each adductor canal were also analyzed. Findings were homogeneous inside each group. The connective tissue of the canal was continuous with the outer layer of the vessels in both groups. The pattern of concentric, thick collagen type I bundles in fetal specimens was replaced by a diffuse network of compact collagen bundles with several transversal fibers and an impressive content of collagen III fibers. Elastic fibers in adults were not concentrated in the thick bundles but dispersed in line with the transversal fiber system. A dynamic compression mechanism with or without an evident constricting fibrous band has been proposed previously for adductor canal syndrome, possibly involving the connective tissue inside the canal. The vessels may not slide freely during movement. These age-related modifications in normal individuals may represent necessary conditions for this syndrome to develop.

  10. Agreement between visual and goniometric assessments of adductor and popliteal angles in infants

    Full Text Available Context: Amiel-Tison method is a commonly used technique for assessing tone and neurological status of infants. There is a paucity of data on the reliability of visual assessment of angles, a component of this method. Subjects and Methods: We compared the visual and the goniometric assessment of adductor and popliteal angles in infants with hypertonia and neurologically normal controls. A total of 16 infants with hypertonia and 15 normal infants underwent blinded assessment of the adductor and popliteal angles. Statistical Analysis: The mean and standard deviation for the difference between visual and goniometric measurements were calculated for popliteal and adductor angles. Results: The mean differences between visual and goniometric measurements for the popliteal angle were 4.94 (SD3.40 and 8.73 (SD6.10 degrees for the cases and controls respectively. Similarly, the values for adductor angle measurements were 8.94 (SD8.23 and 14.47 (SD8.47 degrees respectively. Conclusion: The deviation of visual assessment from goniometric measurement was found to be less for popliteal angle measurement as compared to adductor angle measurements. It was note-worthy that the difference was less for the measurements of children with spasticity.

  11. Activation-induced force enhancement in human adductor pollicis.

    2009-10-01

    It has been known for a long time that the steady-state isometric force after muscle stretch is bigger than the corresponding force obtained in a purely isometric contraction for electrically stimulated and maximal voluntary contractions (MVC). Recent studies using sub-maximal voluntary contractions showed that force enhancement only occurred in a sub-group of subjects suggesting that force enhancement for sub-maximal voluntary contractions has properties different from those of electrically-induced and maximal voluntary contractions. Specifically, force enhancement for sub-maximal voluntary contractions may contain an activation-dependent component that is independent of muscle stretching. To address this hypothesis, we tested for force enhancement using (i) sub-maximal electrically-induced contractions and stretch and (ii) using various activation levels preceding an isometric reference contraction at 30% of MVC (no stretch). All tests were performed on human adductor pollicis muscles. Force enhancement following stretching was found for all subjects (n=10) and all activation levels (10%, 30%, and 60% of MVC) for electrically-induced contractions. In contrast, force enhancement at 30% of MVC, preceded by 6s of 10%, 60%, and 100% of MVC was only found in a sub-set of the subjects and only for the 60% and 100% conditions. This result suggests that there is an activation-dependent force enhancement for some subjects for sub-maximal voluntary contractions. This activation-dependent force enhancement was always smaller than the stretch-induced force enhancement obtained at the corresponding activation levels. Active muscle stretching increased the force enhancement in all subjects, independent whether they showed activation dependence or not. It appears that post-activation potentiation, and the associated phosphorylation of the myosin light chains, might account for the stretch-independent force enhancement observed here.

    Shixin Hao

    Full Text Available In this study, UV (ultraviolet and IR (infrared radiation spectral analysis were integrated to identify the pigment in the adductor muscle scar of the Pacific oyster Crassostrea gigas. The pigment was extracted from the adductor muscle scars of cleaned oyster shells that were pulverized, hydrolyzed in hot hydrochloric acid, purified with diethyl ether, and dissolved in 0.01 mL/L NaOH. The maximum absorption of the pigment in the UV absorption spectrum within the range of 190-500 nm was observed between 210-220 nm. The UV absorbance decreased with increasing wavelength which was consistent with the UV spectral absorption characteristics of melanin. In addition, Fourier transform infrared spectroscopy scanning revealed characteristic absorption peaks that emerged near 3440 cm-1 and 1630 cm-1, which was consistent with infrared scanning features of eumelanin (a type of melanin. This study has demonstrated for the first time that the pigment in the adductor muscle scar of the Pacific oyster is melanin, hinting that the adductor muscle could be another organ pigmenting the mollusc shell with melanin other than mantle.

    Here, we present the case of an 86-year-old woman with vulvar carcinoma requiring surgical resection and with Parkinson's disease with severe spasticity and contractures of the lower extremities. Because of the patient's severe contractures and spasticity (her knees could only be separated by 2 cm with sustained abducting force), surgical positioning and access to the vulva were impossible. The patient was admitted, intending to undergo surgery after injection with botulinum toxin (BTX) to hip adductors and intensive physical therapy. After confirmed healed hip arthroplasty, the patient underwent BTX injection (400 U) to her bilateral adductor brevis, adductor longus, adductor magnus, and semimembranosus and semitendinosus muscles on day 2 of her hospital stay. On day 3, a physical therapist began a twice-a-day stretching program. An adjustable abduction brace was custom-made to provide sustained stretching. On day 9, the patient underwent wide local excision of vulvar carcinoma with the abductor brace in place. The patient tolerated the surgery well and was discharged home on day 11 with continuous physical therapy. Upon discharge, the distance between the patient's knees was 14 cm. This unique case demonstrated a new indication for BTX treatment in the preoperative setting to allow surgical positioning and access.

  10. Effects of ankle extensor muscle afferent inputs on hip abductor and adductor activity in the decerebrate walking cat.

    Bolton, D A E; Misiaszek, J E

    2012-12-01

    Electrical stimulation of the lateral gastrocnemius-soleus (LGS) nerve at group I afferent strength leads to adaptations in the amplitude and timing of extensor muscle activity during walking in the decerebrate cat. Such afferent feedback in the stance leg might result from a delay in stance onset of the opposite leg. Concomitant adaptations in hip abductor and adductor activity would then be expected to maintain lateral stability and balance until the opposite leg is able to support the body. As many hip abductors and adductors are also hip extensors, we hypothesized that stimulation of the LGS nerve at group I afferent strength would produce increased activation and prolonged burst duration in hip abductor and adductor muscles in the premammillary decerebrate walking cat. LGS nerve stimulation during the extensor phase of the locomotor cycle consistently increased burst amplitude of the gluteus medius and adductor femoris muscles, but not pectineus or gracilis. In addition, LGS stimulation prolonged the burst duration of both gluteus medius and adductor femoris. Unexpectedly, long-duration LGS stimulus trains resulted in two distinct outcomes on the hip abductor and adductor bursting pattern: 1) a change of burst duration and timing similar to medial gastrocnemius; or 2) to continue rhythmically bursting uninterrupted. These results indicate that activation of muscle afferents from ankle extensors contributes to the regulation of activity of some hip abductor and adductor muscles, but not all. These results have implications for understanding the neural control of stability during locomotion, as well as the organization of spinal locomotor networks. PMID:22972967

    Full Text Available The GSI (General Symptom Index of the Symptom Checklist 90 R (SCL 90 R (as a global indicator of the severity of psychiatric symptoms of 27% of the spasmodic torticollis (ST sample fell outside the 95% range of the normal control group (two standard deviations. Patients with a higher GSI were younger, more functionally disabled and subject to higher psychosocial stress due to the illness. The highest scores were reached on the subscales of somatization, interpersonal sensitivity and depression. On the depression scale, 23% of the patients' scores were abnormal. This scale correlated significantly with the neurological signs, particularly the TSUI-index and laterocollis. A statistically significant correlation also existed between psychiatric morbidity and a family history of mental disorder. More than 50% of the patients reported that stressful life events had triggered their illness. In order of frequency, a death came first, followed by marital strife, changes in employment and family arguments. The data suggest that psychopathology in ST should generally be considered as a result of a variety of interacting factors, biological, psychological and social.

    Painful adductor muscle contracture is an important cause of failure during rehabilitation following total hip arthroplasty (THA). Adductor muscle contracture may be caused by postoperative muscle retractions, adhesive capsulitis, postoperative leg-length inequalities caused by implant failure, or preexisting hip pathologies. A 34-year-old woman experienced a persistent painful contracture into the left adductor magnus muscle after THA. She had no leg-length inequalities and, according to the Medical Research Council scale (grades 0-5), muscle strength of the quadriceps was 5/5 for the right side and 3/5 for the left. The degree of functionality according to the Harris hip score (HHS) was 16/100 in the left hip. The pain level, measured with the visual analog scale (VAS), was 7/10. The patient was unable to fully adhere to the rehabilitation program and walked with a limp during the stance phase of gait. After 7 days of treatment with injections of botulinum toxin type A into the left adductor magnus muscle (dose, 150 UM) and subsequent rehabilitation, a great reduction of painful contracture was observed (VAS score, 2/10). The procedure was well tolerated and no adverse effects were noted. After 20 days, hip articular range of motion and gait had improved (HHS score, 75/100). The clinical effects of botulinum toxin type A were present at 2-month follow-up. This treatment may be a viable alternative for the management of painful adductor muscle contracture after THA, without significant side effects. PMID:19824593

    1992-01-01

    Thirty patients diagnosed as suffering from non-organic dysphonia were assigned to one of three treatment groups: direct therapy, indirect and no treatment for a period of 8 weeks. Therapeutic outcome was evaluated by independent judges, patient self-evaluation, electrolaryngograph ratings and measures of fundamental frequency. The direct treatment group showed the most significant improvement in the return to normal voice functioning followed by the indirect treatment group. One patient in the control group showed improvement without any intervention. This study provides evidence in support of the effectiveness of both direct and indirect therapy in the treatment of non-organic dysphonia and raises questions concerning individual patient responses to these approaches.

    1999-06-01

    Dysphonia (hoarseness) is a common clinical condition and, if persistent, patients are referred to otolaryngology clinics for clinical examination. During the examination, a clinical distinction is often made among three types of patients: (1) those with a clear organic basis for dysphonia (cancer, vocal cord palsy): (2) those with some degree of organic pathology; and (3) those with an apparently functional etiology. Functional patients are often characterized as having a psychogenic disorder. This study assessed the psychological validity of the functional category in 204 out-patients (aged 17 to 87 years) with persistent hoarseness of types (2) and (3). Following clinical examination, a consultant otolaryngologist categorized patients as having functional or organic etiology. Subjects were then compared on measures of personality and psychological distress. Dysphonic subjects showed marked psychological distress compared with norms, and reported significantly more previous psychosomatic symptoms than norms, but there were no differences in personality or psychological distress between organic and functional subgroups of dysphonics.

    Full Text Available Introduction: Laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. Dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. In differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide important information on the presence of neoplastic lesions in order to prevent disease progression via early detection and action.   Materials and Methods: This cross-sectional, descriptive-analytical study was carried out on 197 patients with voice disorders admitted to Ayatollah Rouhani Hospital for video laryngoscopy. Available sampling was used and the results achieved were analyzed using SPSS17 statistical software.   Results: A total of 197 patients (mean age, 40.72 ±15.17 years participated in this study, 56.9% of whom were male. From analysis of video laryngoscopy, organic dysphonia was found to be the most common cause of voice disorders, while functional and neurologic dysphonia were observed in 8.6% and 5.6% of patients, respectively. Vocal nodules and Reinke's edema were among the most common causes of organic dysphonia, with a frequency of 24.4% and 23.4%, respectively; while laryngeal carcinoma accounted for 2.5% of all diagnosed cases with organic causes.   Conclusion:  Since the presence of voice disorders for more than 3 weeks can be a sign of laryngeal dysfunction, early diagnosis using noninvasive methods such as video laryngoscopy and appropriate medical measures can help prevent the disease progression and eliminate the need for actions such as laryngectomy.

    Full Text Available Introduction: Laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. Dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. In differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide important information on the presence of neoplastic lesions in order to prevent disease progression via early detection and action.   Materials and Methods: This cross-sectional, descriptive-analytical study was carried out on 197 patients with voice disorders admitted to Ayatollah Rouhani Hospital for video laryngoscopy. Available sampling was used and the results achieved were analyzed using SPSS17 statistical software.   Results: A total of 197 patients (mean age, 40.72 ±15.17 years participated in this study, 56.9% of whom were male. From analysis of video laryngoscopy, organic dysphonia was found to be the most common cause of voice disorders, while functional and neurologic dysphonia were observed in 8.6% and 5.6% of patients, respectively.

    A case of spasmodic torticollis with thoracic outlet syndrome observed for over 18 months is presented and discussed. Maximal head rotation (determining backward gaze) was associated with compression of the brachial plexus between the scaleni muscles and motor, sensory and trophic troubles in the hand. This new syndrome is called after the diviner Manto, quoted by Dante Alighieri in his 'Divina Commedia' (Inferno, XX, 52-56). The etiology was ascribed to subacute toxic effects of methylparathion. Brainstem Auditory Evoked Potentials (BAEPs) demonstrated severe brainstem involvement, maximal in the mesencephalic structures. Clinical and neurophysiological data improved on treatment with L-5-hydroxytryptophan. Finally, BAEPs returned to normal.

    Objective: To observe the therapeuticeffect of scalp acupuncture on cerebral blood flow in pseudobulbar paralysis patients for analyzing mechanisms of scalp-acupunoture in the treatment of wind stroke. Methods: A total of 38 inpatients (26 males and 12 females) were treated with electroacupuncture (EA) of scalp-point Dingzhongxian (MS 5), Dingnie Houxiexian (MS 7), Dingpangxian Ⅱ (MS 9) and Dingnie Qianxiexian (MS 6). Before and after acupuncture treatment, clinical symptoms of dysphagia and dysphonia were compared, and the mean blood flow speed (MBFS) values of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) detected by using Doppler blood flow meter. Results: Following two courses (4 weeks) of scalp-acupuncture treatment, of the 38 cases, 23 had their dysphagia and dysphonia cured (60.5%), 10 (25.3%) had remarkable improvement, 3(7.9% ) experienced improvement and 2 (5.3%) had no apparent changes. Simultaneously, MBFS of ACA, MCA and PCA increased significantly in comparison with that of pre-treatment (P < 0.01 ). Additionally, results also showed that scalp acupuncture could stabilize the blood circulation between both hemispheres of the brain. Conclusion: Scalp acupuncture has a fairly good therapeutic effect in improving stroke caused dysphagia and dysphonia and in facilitating cerebral blood flow.

    Mood, anxiety, and other psychological symptoms are common in dystonic patients suffering from blepharospasm (BSP) and spasmodic torticollis (ST). Since sexual well-being is an important aspect of mental health, here, we investigated whether these patients may also experience a worsening of their sexual life. In particular, quality of sexual life was evaluated in patients suffering from BSP (N = 30), ST (N = 30), and in a control group of patient with Hemifacial spasm (HFS; N = 30), undergoing botulinum toxin type A therapy. A group of 30 age-matched healthy volunteers constituted an additional control group. Patients were evaluated just before the periodic injection of botulinum toxin. Sexual functioning was assessed using the Sexual Functioning Inventory, a reduced form of the Golombok Rust Inventory, previously employed in patients with Parkinson’s disease. Depression (Beck Depression Inventory) and anxiety (STAI-X1/X2) were also assessed. Results revealed that sexual functioning was significantly affected in patients with BSP, ST, and HFS with respect to healthy controls. Dystonic patients manifested more sexual dysfunction than patients with HFS. Overall, females had a poorer quality of sexual life than males and, among females, women with BSP were the most dysfunctional. Psychological symptoms were present in patients with dystonia, but not in patients with HFS. As discussed in the paper, several factors might be taken into account to explain worse quality of sexual life in patients with dystonia compared to patients with hemifacial spasm. Among them an important role might be played by the central origin of dystonia pathophysiology (i.e., altered activity of cortico-striato-thalamic-cortical circuits). Future investigations are necessary to further explore these preliminary findings, considering that this is the first time that sexual well-being is evaluated in patients with BSP, ST, and HFS, and comparable data are not available.

    2014-01-01

    Full Text Available Background: Trachyspermum ammi is a plant of umbelliferae family and has been traditionally used in the treatment of many gastrointestinal disorders such as indigestion, colic, and diarrhea. Our previous study demonstrated that aqueous extract of Trachyspermum ammi reduced the contractile activity of rat′s ileum. Aims: This study was designed to examine the effect of Trachyspermum ammi essence on acetylcholine-induced contraction in isolated rat′s ileum. Materials and Methods: In this experimental procedure, the tissue samples were suspended from the transducer lever and mounted on the organ bath containing Tyrode′s solution. Isotonic responses were recorded by using an isotonic transducer and the amplitude of contractions. This process was induced by cumulative logarithmic concentrations of acetylcholine before and after exposing tissue by saline and different concentrations of essence. Results: The chemical constituents of the essence from distillate extract of Trachyspermum ammi seeds were studied by gas chromatography mass spectrometry (GC-MS and the chemical analysis showed many components in which thymol was the main constituent. Our findings showed that the essence derived from the extract in all concentrations used in this study (0.002, 0.005, and 0.01% V/V significantly reduced acetylcholine-induced contractions (47.34, 60.46, and 86%, respectively, P < 0.05. The same concentrations of the essence also exhibit a significant anti-spasmodic action on acetylcholine-induced contractions (0.1,88.3, and 90.7%, respectively, P < 0.05. Conclusion: Since thymol was the major constituent of our samples of Trachyspermum ammi, the relaxant effect observed in this study is probably due to this agent which can exert an anti-cholinergic property.

    Insertional tendinopathy of the adductors and rectus abdominis is common in male athletes, especially in soccer players. It may be worsened by physical activity and it usually limits sport performance. The management goal in the acute phase consists of analgesic and anti-inflammatory drugs and physical rehabilitation. In the early stages of rehabilitation, strengthening exercises of adductors and abdominal muscles, such as postural exercises, have been suggested. In the sub-acute phase, muscular strength is targeted by overload training in the gym or aquatherapy; core stability exercises seem to be useful in this phase. Finally, specific sport actions are introduced by increasingly complex exercises along with a preventive program to limit pain recurrences. PMID:23738289

    Only a few cases of adductor longus tendon ruptures have been reported in the literature and - there are no clear criteria for conservative or surgical treatment. A case of traumatic rupture of the right distal adductor longus tendon is presented in an elite soccer player, which was surgically repaired. The condition was managed conservatively primarily. However, after 2 months, a palpable mass remained on the medial side of the thigh, and the patient had pain after moderate everyday load and insufficient strength of the right leg during physical exercise. It was decided to explore ruptured tendon surgically and reattach to the femur. Full function of the right leg was achieved at 3 months after surgical repair. At 6 months postoperatively, the patient had returned to soccer at the same level. PMID:27132783

    Full Text Available Abstract Background Fumaria parviflora Linn. (Fumariaceae, is a small branched annual herb found in many parts of the world including Saudi Arabia and Pakistan. This study was designed to provide pharmacological basis for the medicinal use of Fumaria parviflora in gut motility disorders. Methods The in-vivo prokinetic and laxative assays were conducted in mice. Isolated intestinal preparations (ileum and jejunum from different animal species (mouse, guinea-pig and rabbit were separately suspended in tissue baths containing Tyrode's solution bubbled with carbogen and maintained at 37°C. The spasmogenic responses were recorded using isotonic transducers coupled with PowerLab data acquisition system. Results The aqueous-methanol extract of Fumaria parviflora (Fp.Cr, which tested positive for the presence of alkaloids, saponins, tannins and anthraquinones showed partially atropine-sensitive prokinetic and laxative activities in the in-vivo in mice at 30 and 100 mg/kg. In the in-vitro studies, Fp.Cr (0.01-1 mg/ml caused a concentration-dependent atropine-sensitive stimulatory effect both in mouse tissues (jejunum and ileum, and rabbit jejunum but had no effect in rabbit ileum. In guinea-pig tissues (ileum and jejunum, the crude extract showed a concentration-dependent stimulatory effect with higher efficacy in ileum and the effect was partially blocked by atropine, indicating the involvement of more than one types of gut-stimulant components (atropine-sensitive and insensitive. This could be a plausible reason for the greater efficacy of Fp.Cr in gut preparations of guinea-pig than in rabbit or mouse. Conclusions This study shows the prokinetic, laxative and spasmodic effects of the plant extract partially mediated through cholinergic pathways with species and tissue-selectivity, and provides a sound rationale for the medicinal use of Fumaria parviflora in gut motility disorders such as, indigestion and constipation.

    The examination covers the personality of 20 functional dysphonics, 14 individuals suffering from organic voice disorders and a group of 20 control persons when exposed to stress and its working up. In examining the group of functional dysphonics a significant positive self-assessment regarding their personality with a clear tendency to restraint has become clear. In comparison with the control persons an intensified anxiety state in situations causing stress is the result. Thus the influence of life events has been shown to have an important effect on the etiopathogenesis of functional dysphonia.

    Full Text Available The purpose of this paper is to review the methods used for the assessment of muscular tension dysphonia (MTD. The MTD is a functional voice disorder associated with abnormal laryngeal muscle activity. Various assessment methods are available in the literature to evaluate the laryngeal hyperfunction. The case history, laryngoscopy, and palpation are clinical methods for the assessment of patients with MTD. Radiography and surface electromyography (EMG are objective methods to provide physiological information about MTD. Recent studies show that surface EMG can be an effective tool for assessing muscular tension in MTD.

    The challenge of joining dissimilar advanced materials has led researchers around the world to search for new and more efficient solutions. This way, we can highlight the muscle-shell attachment in mollusk, which possessed high strength and toughness. In order to make clear how this "bi-material interface" derives its superior mechanical properties, the morphological features of the adductor muscle scar in Patinopecten yessoensis was investigated by means of confocal laser scanning microscopy (CLSM). This scar area was found to consist of a myostracum with many evenly distributed pit structures and a fracture section with a parallel arranged prism-like structure. The measured values of the distribution density, diameter, and depth of those pit structures were 24 ± 4/49,152 μm2, 7.36 ± 2.47 μm, and 1 ± 0.31 μm respectively. Profile of each pit wall was arc curve without closed angle. Furthermore, CLSM micrographs showed that considerable micro pits (0.1-0.9 μm in diameter) distribute round the pit wall and on the pit bottom. This special micromorphology is the first report on the adductor muscle scar in scallop. In addition, the mineral state and mechanical property of the scar surface was analyzed by XRD and nanoindentation test respectively. In general, the study results presented in this work elucidated that the adductor muscle of P. yessoensis was attached to the shell by insertion of collagen fibers and fibril bundles branched from themselves into pits on the myostracum. This specific connection mechanism can increase the strength of the interface without compromising its ductility and toughness. PMID:26202606

    Full Text Available Diabetic myonecrosis is a rare and underdiagnosed complication of long-standing, uncontrolled diabetes. It usually occurs in patients with long-standing diabetes in the presence of microvascular complications. Thigh muscles are more commonly affected and the usual presentation is thigh swelling with or without pain, systemic features being rare. Magnetic resonance imaging is the gold standard for diagnosis. Most patients recover spontaneously with bed rest, adequate analgesia and good glycemic control. We present a case of recurrent myonecrosis of adductor muscles of the thigh in a patient with long standing type 2 diabetes mellitus who recovered with conservative management.

  19. Effective dysphonia detection using feature dimension reduction and kernel density estimation for patients with Parkinson's disease.

    Directory of Open Access Journals (Sweden)

    Shanshan Yang

    Full Text Available Detection of dysphonia is useful for monitoring the progression of phonatory impairment for patients with Parkinson's disease (PD, and also helps assess the disease severity. This paper describes the statistical pattern analysis methods to study different vocal measurements of sustained phonations. The feature dimension reduction procedure was implemented by using the sequential forward selection (SFS and kernel principal component analysis (KPCA methods. Four selected vocal measures were projected by the KPCA onto the bivariate feature space, in which the class-conditional feature densities can be approximated with the nonparametric kernel density estimation technique. In the vocal pattern classification experiments, Fisher's linear discriminant analysis (FLDA was applied to perform the linear classification of voice records for healthy control subjects and PD patients, and the maximum a posteriori (MAP decision rule and support vector machine (SVM with radial basis function kernels were employed for the nonlinear classification tasks. Based on the KPCA-mapped feature densities, the MAP classifier successfully distinguished 91.8% voice records, with a sensitivity rate of 0.986, a specificity rate of 0.708, and an area value of 0.94 under the receiver operating characteristic (ROC curve. The diagnostic performance provided by the MAP classifier was superior to those of the FLDA and SVM classifiers. In addition, the classification results indicated that gender is insensitive to dysphonia detection, and the sustained phonations of PD patients with minimal functional disability are more difficult to be correctly identified.

    2011-12-01

    Full Text Available Background and Aim: Vocal abuse and misuse are the most frequent causes of voice disorders. Consequently some therapy is needed to stop or modify such behaviors. This research was performed to study the effectiveness of vocal hygiene program on perceptual signs of voice in people with dysphonia.Methods: A Vocal hygiene program was performed to 8 adults with dysphonia for 6 weeks. At first, Consensus Auditory- Perceptual Evaluation of Voice was used to assess perceptual signs. Then the program was delivered, Individuals were followed in second and forth weeks visits. In the last session, perceptual assessment was performed and individuals’ opinions were collected. Perceptual findings were compared before and after the therapy.Results: After the program, mean score of perceptual assessment decreased. Mean score of every perceptual sign revealed significant difference before and after the therapy (p≤0.0001. «Loudness» had maximum score and coordination between speech and respiration indicated minimum score. All participants confirmed efficiency of the therapy.Conclusion: The vocal hygiene program improves all perceptual signs of voice although not equally. This deduction is confirmed by both clinician-based and patient-based assessments. As a result, vocal hygiene program is necessary for a comprehensive voice therapy but is not solely effective to resolve all voice problems.

  1. Dysphonia: medical treatment and a medical voice hygiene advice approach. A prospective randomised pilot study.

    2004-07-01

    For many years all patients with dysphonia referred to in the literature as resulting from non-organic (functional) voice disorders were sent to speech therapy. Medical diagnoses were not taken into account. In our earlier Cochrane review on vocal cord nodules we discovered that evidence-based research in the area of benign voice disorders with dysphonia, and with or without slight benign swellings including nodules on the vocal cords, was lacking at that time. Therefore, a prospective randomised pilot study based on our Cochrane review has been made on dysphonic patients with non-organic (function provoked?) voice disorders as the basis for further evidence-based studies. Medical treatment was based on the scientific approach that once a micro-organic disorder caused by reflux, infection, allergy or environmental irritatants (e.g., dust or noise in the workplace) was discovered by very careful anamnesis and systematic objective routine analyses and was treated effectively, with documentation, the non-organic voice disorder disappeared, as, e.g., in the case of a diagnosis and treatment of helicobakter pylori. The reason is that the mucosal swelling/dysfunction of the vocal cords is secondary. In order to try to understand why the recommendation to all these patients for many years was only voice therapy, which the speech therapists "felt to be effective", updated voice-hygiene advice (for posture, accents of the diaphragm, intonation pattern and resonance) was given by experienced laryngologists, randomised with the updated medical diagnosis/therapy in order to elucidate what effect the training might have. No evidence-based studies in the literature document any effect. The crucial point seemed to be that doctors mostly did not examine any other diagnoses other than the "dysphonia" and did not dig down to any of the medical reasons when the vocal fold diagnosis of "non- organic disorders" was made. This should be changed in the future. This pilot study was based

    The adductor muscle scar (AMS) is the fixation point of adductor muscle to the shell. It is an important organic-inorganic interface and stress distribution area. Despite recent advances, our understanding of the structure and composition of the AMS remain limited. Here, we report study on the AMS of three bivalves:Mytilus coruscus, Chlamys farreri andRuditapes philippinarum. Results showed that there were significant differences among their AMS structures. BothM. coruscus andC. farreri were found to have a columnar layer above the nacreous platelet shell structure at the AMS and this layer was more organized inM. coruscus. There was no distinguishable two-layer structure inR. philippinarum. Atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FT-IR) results showed that the AMS was much smoother than the nacreous inner shell in all the three species and the AMS had minor different compositions from the nacreous shell layer. SDS-PAGE (sodium dodecyl-sulfate polyacrylamide gel electophoresis) study of the proteins isolated from the interface indicated that there was a 70 kDa protein which seemed to be specifically located to the highly organized columnar AMS structure inMytilus coruscus. Further analysis of this protein showed it contained high level of Asx (Asp+Asn), Glx (Glu+Gln) and Gly. The special structure and composition of the AMS might play important roles in the stability, adhesion and function at this stress distribution site.

    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.(2) Here, we report a patient carrying p.P525L FUS mutation and experiencing an aggressive course of ALS presenting with dysphonia and diplopia.

    In the United States 6.8% of men, women, and children report current voice problems and approximately 29% will report some problems during their lifetime. Often this dysphonia is due to pathologies of the vocal folds. The authors (a physicist and a speech pathologist) describe an interdisciplinary approach that shows promise of detecting physiological abnormalities of the vocal folds from an analysis of the Fourier spectrum of spoken ``tokens.'' The underlying principle maintains that the normal human vocal fold is a linear oscillator that emits overtones that are very nearly precise integral values of the fundamental. Physiological problems of the vocal folds, however, introduce mechanical non-linearities that manifest themselves as frequency deviations from the ideal harmonic (that is, integral) values. The authors quantify this inharmonicity, describing and illustrating how one can obtain and analyze such data. They outline, as well, a proposed program to assess the clinical sensitivity and significance of the analysis discussed in this work.

    In previous investigations, typical phonetogram differences have been revealed between healthy and pathological voices: the average maximum and minimum sound pressure levels that a patient suffering from non-organic dysphonia can produce at different fundamental frequencies deviate significantly from the corresponding values for a healthy voice. The subglottal pressure, being the primary tool for regulating the sound pressure level of voice, was estimated from the oral pressure during the voiceless stop/p/in 10 female and 10 male subjects with normal voices and in 10 female and 10 male non-organic dysphonic patients. In loud phonation, the female patients had significantly lower values than the female healthy subjects, while no corresponding significant difference was seen between the male subjects. In soft phonation, the male patients had significantly higher values than the normal healthy subjects, while the females showed no significant difference.

    Mechanical properties of skeletal muscles are often studied for controlled, electrically induced, maximal, or supra-maximal contractions. However, many mechanical properties, such as the force-length relationship and force enhancement following active muscle stretching, are quite different for maximal and sub-maximal, or electrically induced and voluntary contractions. Force depression, the loss of force observed following active muscle shortening, has been observed and is well documented for electrically induced and maximal voluntary contractions. Since sub-maximal voluntary contractions are arguably the most important for everyday movement analysis and for biomechanical models of skeletal muscle function, it is important to study force depression properties under these conditions. Therefore, the purpose of this study was to examine force depression following sub-maximal, voluntary contractions. Sets of isometric reference and isometric-shortening-isometric test contractions at 30% of maximal voluntary effort were performed with the adductor pollicis muscle. All reference and test contractions were executed by controlling force or activation using a feedback system. Test contractions included adductor pollicis shortening over 10 degrees, 20 degrees, and 30 degrees of thumb adduction. Force depression was assessed by comparing the steady-state isometric forces (activation control) or average electromyograms (EMGs) (force control) following active muscle shortening with those obtained in the corresponding isometric reference contractions. Force was decreased by 20% and average EMG was increased by 18% in the shortening test contractions compared to the isometric reference contractions. Furthermore, force depression was increased with increasing shortening amplitudes, and the relative magnitudes of force depression were similar to those found in electrically stimulated and maximal contractions. We conclude from these results that force depression occurs in sub

Results Eight cases of compensatory type were misdiagnosed as chorditis, chronic laryngitis and two of hypertrophic type were misdiagnosed as chronic laryngitis and vocal polyp. Ventricular bands dysphonia in all cases disappeared after various therapeutic measures including voice therapy, surgical and drug treatment. Conclusion The clinical manifestations of ventricular bands dysphonia are untypical. It can easily be misdiagnosed as other voice diseases. Meticulous voice assessment, and laryngeal videostroboscopy should be considered.

    Groin pain is a condition with a high prevalence in young Australian football players. It is considered that early identification of this condition allows for optimal management. Eighty-six players from two elite under-age Australian football sides were screened weekly for hip adductor muscle strength, using a hand-held dynamometer and for the onset of groin pain. The maximum variation in the average hip adductor muscle strength values of the sample was a 2.6% decrease from baseline in week 7 of the study. Twelve players (14% of the sample studied) reported groin pain for two consecutive weeks and were considered to have an onset of groin injury. The mean hip adductor muscle strength of these players was decreased significantly from baseline by an average of 11.75+/-2.50% at the week of pain onset (F=264.76 (1,11), padductor muscle strength is decreased both preceding and during the onset of groin injury in elite under-age Australian footballers.

    Aim of the present study was to investigate the prevalence of allergy in patients affected by both organic and/or functional vocal fold disorders. The secondary aim was to assess the correlation between sex and allergy in dysphonic patients. A retrospective chart review was performed on dysphonic patients. A total of 76 patients underwent fiberoptic endoscopy to assess the objective picture. Logistic regression analyses have been conducted to assess the association between sex and the outcome variables. The laryngoscopic examination revealed the presence of poor glottic closure in 32.9%, hyperkinesias in 11.8%, redness in 11.84%, polyps in 5.3%, oedema in 3.95%, vocal fold hypertrophy in 5.3%, nodules in 42.1%, cordectomy in 2.6%. Allergic rhinitis was present in 56.6%, milk intolerance in 13.2%, asthma in 9.2%, atopic dermatitis in 3.9%, drugs intolerance in 11.8%. A total of 76.32% patients presenting with dysphonia were allergic. A statistically significant association was found between female sex and presence of allergy. In conclusion, allergy testing should be performed routinely on female professional voice users. Mild respiratory disorders must be taken into serious consideration in female professional voice users, who may primarily complain of vocal dysfunction rather than upper and lower respiratory diseases.

    Forty-five patients diagnosed as having non-organic dysphonia were assigned in rotation to one of three groups. Patients in one group received no treatment and acted as a control group. Patients in the other two groups received a programme of either 'indirect' therapy or 'direct with indirect' therapy, respectively. A self-report questionnaire of vocal performance, observed ratings of voice quality, and computer-derived acoustic measurements (signal-to-noise ratio, pitch perturbation and amplitude perturbation) were carried out on all patients before and after treatment to evaluate the changes in voice quality over time. There was a significant difference between the three groups on the self-report questionnaire, voice quality ratings and pitch perturbation measurements (P = < 0.05). Thirteen out of 15 control patients showed no significant change on any of the measures. Seven patients who received indirect treatment showed significant improvement in voice quality following treatment. Fourteen out of 15 patients who received direct treatment showed significant improvement in voice quality.

    Although many studies have been focused on muscle synergies in the lower limbs, synergies of the thigh muscles during cycling have not been investigated in detail. We examined synergies of the thigh muscles including the vastus intermedius (VI) and adductor magnus (AM) while cycling. Eight healthy men pedaled at 20%, 40%, 60%, 80% and 100% of maximal aerobic power output at a constant cadence of 60 rpm. Surface electromyography (EMG) recorded signals from the deep VI and the three superficial quadriceps femoris (QF) muscles, the two hamstrings and the AM. The root mean square of the EMG signal was averaged every 2° of crank rotation and normalized by the peak value for each muscle. We used factor analysis to assess normalized EMG recordings while cycling and to identify thigh muscle synergies. The VI, the superficial QF muscles and the AM dominated the first muscle synergy at all power output levels. The AM also formed a second synergy with the two hamstrings at all power output levels. These results suggest that the VI coordinates with the other QF and AM muscles, and that the AM coordinates with the QF and hamstring muscles while cycling.

    The relation between measurements of colour made in the m. adductor (AD) at 45min or 20 h post mortem and the quality, assessed subjectively in terms of colour and waterholding capacity, of the m. longissimus (LD) in the loin was examined. The study used data from 100 pig carcasses exhibiting a wide range of meat quality from extreme PSE (pale, soft and exudative) to extreme DFD (dark, firm and dry). The subjective assessments were confirmed by objective measures of paleness (reflectance) and waterholding capacity (drip loss in storage) in the LD. Lightness (L(∗)) measured at 20h post mortem in the AD was the best potential predictor of loin muscle quality, explaining 59% of the variation in subjective and objective quality measures. Comparable measurements at 45min post mortem explained between 21% and 44% of the variation. The equation that described the relation between AD Lightness (L(∗)) and subjectively assessed LD quality was derived. This could be used to transpose the AD L(∗) values from a population of slaughtered pigs into nominal subjective scores for the LD, allowing the frequency of the five subjective quality groups (extremely DFD, slightly DFD, normal, slightly PSE, and extremely PSE) in the population of carcasses to be defined.

    The neuroanatomy of the larynx was explored in seven dogs to assess whether there is motor innervation to the thyroarytenoid (TA) muscle from the external division of the superior laryngeal nerve (ExSLN). In 3 animals, such innervation was identified. Electrical stimulation of microelectrodes applied to the ExSLN resulted in contraction of the TA muscle, indicating that this nerve is motor in function. This was confirmed by electromyographic recordings from the TA muscle. Videolaryngostroboscopy revealed improvement in vocal fold vibration following stimulation of the ExSLN compared to without it. Previously, the TA muscle was thought to be innervated solely by the recurrent laryngeal nerve. This additional pathway from the ExSLN to the TA muscle may have important clinical implications in the treatment of neurologic laryngeal disorders such as adductor spasmodic dysphonia. PMID:9228862

    2010-12-01

    Full Text Available In the southern escarpment of the Serra da Mantiqueira, northeast geographic divider between the State of São Paulo and Minas Gerais, there was an environmental accident caused by the disruption of an adductor whose purpose is to lead the water from a reservoir located at an altitude of 1820 m to the machine house where there is an electric generator located at 750 m.  This accident resulted in the formation of a scar on the hillside forest, with removal of soil and vegetation. To reverse the erosion processes, a methodology was developed consisting of the use of four barriers (numbered I to IV formed by seedlings of Bambusa mutiplex (Lour., whose purpose was to divert the water runoff in order to provide the regeneration of native vegetation. Stalks of bamboo intercropped with Bambusa multiplex were used to contain debris in two gullies formed by erosion. The development of vegetation was monitored for 18 months and evaluated by the application of a Leopold Matrix composed of 5 points, which are: erosion, regeneration of vegetation, success of bamboo planting, installed conservation structures and functionality. The purpose of the matrix was to demonstrate the effectiveness of interventions using bamboo. The result of the classification matrix enabled the quantitative and qualitative classification of the interventions, resulting in five levels, where the barriers I, II and IV were considered to be of very high efficiency, and barrier III was considered to be of high efficiency. The contention of the gully was considered to be of medium to very high efficiency.

    To examine the anatomic MRI characteristics of the adductor magnus mini hamstring (AMMH) and explore its involvement in cases of hamstring avulsion. An IRB-approved retrospective review of patients undergoing ''hamstring protocol'' MRI between March 2009 and June 2014 was performed. Two musculoskeletal radiologists recorded multiple AMMH anatomic characteristics and involvement in cases of hamstring avulsion. Seventy-six AMMHs were analyzed in 66 patients [35 females and 31 males, mean age 49.3 ± 15.2 years (range 17-81)]. Eleven percent of AMMHs were poorly visualized, 51 % visualized, and 37 % well visualized. Seven percent demonstrated round, 73 % ovoid, and 21 % flat/lenticular tendon morphologies. Most (88 %) demonstrated typical origins. Average cross-sectional area (CSA) was 22.4 ± 10.6 mm{sup 2} (range 6-56), diameter was 7.2 ± 2.5 mm (range 2.9-15), medial distance from the semimembranosus tendon was 7.5 ± 2.5 mm (range 3-14), and tendon length was 6.8 ± 3.3 cm (range 1.2-14.1). There was no gender difference in AMMH anatomic measurements or correlation between age and CSA or diameter. Of 17 complete hamstring avulsion cases, the AMMH was intact in 13, partially torn in 3, and completely torn in 1. The AMMH is a constant finding with variable anatomic characteristics. It is visualized or well visualized by MRI in 88 % of cases and is a sizable tendon located in close proximity to the semimembranosus tendon. Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

  2. The dependence of force enhancement on activation in human adductor pollicis.

    2006-09-01

    It has been well recognized that the steady-state isometric force after active muscle/fiber stretch is greater than the corresponding isometric force for electrically stimulated muscles and maximal voluntary contractions (MVC). However, recent evidence obtained for sub-MVC suggests that force enhancement properties are different from those observed for electrically induced and MVC. Specifically, it appears that force enhancement is activation-dependent and that there is a subject-specific threshold for force enhancement in sub-MVC. To address these suggestions, the relationship between force enhancement and voluntary activation during stretch was investigated in 11 healthy subjects. Human adductor pollicis muscles were studied and force enhancement was measured while muscle activation during the steady-state isometric phase was controlled at a level of 30% of MVC. In order to study the effects of activation on force enhancement, subjects performed stretch contractions at 0, 10, 30, 60, and 100% of maximal voluntary effort while the steady-state isometric force after stretch, obtained at 30% of activation in all cases, was compared to the corresponding values measured in the isometric reference contractions. There was no force enhancement if muscle stretching occurred passively but all subjects showed force enhancement when muscle stretching occurred at maximal voluntary effort. When increasing the level of activation during the stretch phase, force enhancement increased, and the number of subjects who showed force enhancement increased as well. We conclude from these results that force enhancement during voluntary contractions is activation-dependent with a threshold that is subject-specific.

  3. Mandibular corpus strain in primates: further evidence for a functional link between symphyseal fusion and jaw-adductor muscle force.

    Previous work indicates that compared to adult thick-tailed galagos, adult long-tailed macaques have much more bone strain on the balancing-side mandibular corpus during unilateral isometric molar biting (Hylander [1979a] J. Morphol. 159:253-296). Recently we have confirmed in these same two species the presence of similar differences in bone-strain patterns during forceful mastication. Moreover, we have also recorded mandibular bone strain patterns in adult owl monkeys, which are slightly smaller than the galago subjects. The owl monkey data indicate the presence of a strain pattern very similar to that recorded for macaques, and quite unlike that recorded for galagos. We interpret these bone-strain pattern differences to be importantly related to differences in balancing-side jaw-adductor muscle force recruitment patterns. That is, compared to galagos, macaques and owl monkeys recruit relatively more balancing-side jaw-adductor muscle force during forceful mastication. Unlike an earlier study (Hylander [1979b] J. Morphol. 160:223-240), we are unable to estimate the actual amount of working-side muscle force relative to balancing-side muscle force (i.e., the W/B muscle force ratio) in these species because we have no reliable estimate of magnitude, direction, and precise location of the bite force during mastication. A comparison of the mastication data with the earlier data recorded during isometric molar biting, however, supports the hypothesis that the two anthropoids have a small W/B jaw-adductor muscle force ratio in comparison to thick-tailed galagos. These data also support the hypothesis that increased recruitment of balancing-side jaw-adductor muscle force in anthropoids is functionally linked to the evolution of symphyseal fusion or strengthening. Moreover, these data refute the hypothesis that the recruitment pattern differences between macaques and thick-tailed galagos are due to allometric factors. Finally, although the evolution of symphyseal fusion

    The incidence of dysphonia among children and adolescents is evaluated internationally at 6 % to 25 %. Nonetheless, hoarseness as a leading symptom among children is often insufficiently recognized by their parents/attachment figures, by the young patients themselves, and even by physicians. In an overview, the hereditary and acquired organic and functional causes - including secondary organic lesions of the vocal folds - their pathomechanisms and the symptoms typical for this age group are presented. For diagnostics suitable for these age groups and developmental stages, modern methods of laryngoscopy (including stoboscopy and real-time laryngoscopy), of functional diagnostics of vocal capacity and quality as well as anamnestic and psychometric procedures for the investigation of possible psychosomatic genesis are available. Frequent therapeutic measures are vocal hygienic counseling and psycho- and family dynamic therapies. Vocal exercise treatments are particularly employed for the consequences of laryngeal surgery and with voice techniques unfavorable as a precondition for increased vocal activity. Operative measures in the sound-producing areas of the vocal apparatus and in the framework of plastic reconstruction concentrate on the optimizing of vocal capacity and quality. In clinical routine, symptoms of dysphonia in children and adolescents should be consciously registered, and any long-term hoarseness, in this age group as well, should be examined by specialized physicians using the methods suitable to the age group and the developmental stage. When the appropriate indications are present, all of the therapeutic options currently available should be discussed.

    2016-01-01

    Objective To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI). Methods Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated. Results There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks. Conclusion The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI. PMID:27606266

    Suburethral tension-free slings (tapes or bands) are an essential component in the operative treatment of urinary incontinence. In the present contribution the influence of the type of suburethral sling (retropubic vs. transobturator) on the myofascial structures of the abdominal, adductor and pelvic floor muscles is examined. For this purpose, 70 patients were prospectively observed clinically and physiotherapeutically. Significant differences were seen in the improvement of the pelvic floor musculature (strength, endurance, speed) after placement of a suburethral sling, irrespective of whether it was of the retropubic or the transobturator type. Thus, after surgical treatment patients should be encouraged to undertake further pelvic floor exercising or this should be prescribed for them. There were no significant changes in the abdominal and adductor muscles but there were slight increases with regard to pain level, pain on palpation, and trigger points after placement of both types of sling; thus this is not a criterion in the decision as to which type of sling to use.

    [Purpose] This study aimed to verify the appropriate number of measurements and the intrarater reliabilities of shoulder joint horizontal adductor muscle strength measurements using a handheld dynamometer (HHD) for geriatric and stroke patients. [Subjects and Methods] The subjects were 40 inpatients, who were divided into two groups: 20 stroke patients in the stroke group (SG), and 20 geriatric patients in the no-stroke group (N-SG). Measurements were performed three times using an HHD with a belt. The reliability was verified using Bland-Altman analysis and the intraclass correlation coefficient (ICC). [Results] ICC (1, 1) was >0.9. A systematic bias was not observed between the first and second measurement values except for the right side in N-SG. A systematic bias between the maximum value obtained during the first and second measurements and third measurement value was observed on the left side in N-SG, and on the non-paralyzed side in SG: the third measurement values were small in both cases. [Conclusion] Intrarater reliabilities were high for shoulder horizontal adductor strength measurements using an HHD with a belt for geriatric and stroke patients. Taking the systematic bias into consideration, these findings suggest that the required number of measurements is two. PMID:26957727

    The aim of the present study was to investigate the immediate effects of static and proprioceptive neuromuscular facilitation (PNF) stretching on the flexibility of hip adductors in female ballet dancers. Forty-five subjects (age: 28.5 ± 8.0 years; minimum two years of ballet training) were randomly assigned to three groups: PNF (contract-release technique), Static, and Control. Subjects in the PNF and Static groups performed four sets of 30 second stretching with an interval of 30 seconds between sets. The control group stayed at rest for the same time spent by the PNF and Static groups during the stretching sessions. Maximal range of motion was measured before and immediately after the experimental and control protocols in all groups. The results indicated significant differences between pre- and post-stretching flexibility in both PNF and Static groups (p stretching methods provoked similar post-exercise acute effects on the maximal range of motion of hip adductors in highly flexible female ballet dancers.

    A case of very severe spasmodic torticollis observed for 18 months is presented and discussed. Head was so rotated that permitted only backward seeing and compressed brachial plexus between scaleni muscles with sensory, motor and trophic troubles in the hand. A toxic aethiology from parathion is likely. Brainstem Acoustic Evoked Potentials (BAEPs) showed in the beginning abnormal responses, especially as refers to waves originating in the mesencephalon. Therapy with L-5-hydroxytryptophan subdued neurological symptoms; a parallel normalization of BAEPs recording was observed. The Authors propose to call this syndrome (spasmodic torticollis with thoracic outlet syndrome) after the mythical diviner Manto, which Dante Alighieri refers to in his "Divina Commedia" (Inferno, XX, 55 e segg.).

    The goal was to identify acoustic and aerodynamic indices that allow the discrimination of a benign organic dysphonic voice from a normal voice. Fifty-three patients affected by dysphonia caused by vocal folds benign lesions, and a control group were subjected to maximum phonation time (MPT) measurements, GRB perceptual evaluations and acoustic/aerodynamic tests. All analyzed variables except the airflow variation coefficient were significantly different between the two groups. The unique significant factors in the discrimination between healthy and dysphonic subjects were the aerodynamic indices of MPT and Glottal efficiency index, and the acoustic index Shimmer. These results show that a combination of three parameters can discriminate a voice deviance and highlight the importance of a multidimensional assessment for objective voice evaluation.

    Parrotfishes (family Labridae: Scarini) are regarded to have important roles for maintaining the ecosystem balance in coral reefs due to their removal of organic matter and calcic substrates by grazing. The purpose of the present study was to clarify the interspecific differences in grazing ability of five parrotfish species (Chlorurus sordidus, C. bowersi, Scarus rivulatus, S. niger and S. forsteni) in relation to interspecific differences in jaw-lever mechanics and the relative weight of the adductor mandibulae (muscles operating jaw closing). The grazing ability was calculated by using stomach contents (CaCO3 weight/organic matter weight) defined as the grazing ability index (GAI). There were significant interspecific differences in GAI (C. sordidus = C. bowersi > S. rivulatus > S. niger = S. forsteni). Teeth of C. sordidus and C. bowersi were protrusive-shape whereas teeth of S. rivulatus, S. niger and S. forsteni were flat-shape. C. sordidus and C. bowersihave jaw-lever mechanics producing a greater biting force and have a larger weight of adductor mandibulae. S. rivulatus has jaw-lever mechanics producing a greater biting force but a smaller weight of adductor mandibulae that produce an intermediate biting force. In contrast, S. niger and S. forsteni have jaw-lever mechanics producing a lesser biting force and have a smaller weight of adductor mandibulae. Feeding rates and foray size of S. rivulatus, S. niger and S. forsteni were greater than C. sordidus and C. bowersi. The degree in bioerosion (GAI × feeding rate) was the largest for S. rivulatusand the smallest for S. forsteni. The degree in bioerosion for C. sordidus was larger than S. niger whereas relatively equal between C. bowersi and S. niger. These results suggest that interspecific difference in GAI was explained by interspecific differences in teeth shape, jaw-lever mechanics and relative weight of adductor mandibulae. The interspecific difference in the degree of bioerosion suggests the

    Full Text Available Myostracum, which is connected from the umbo to the edge of a scar, is not a single layer composed of prismatic layers, but a hierarchically complex multilayered shape composed of minerals and an organic matrix. Through the analysis of the secondary structure, the results revealed that a β-antiparallel structure was predominant in the mineral phase interface between the myostracum (aragonite and bottom folia (calcite. After the complete decalcification and deproteinization, the membrane obtained from the interface between the myostracum buried in upper folia, and the bottom folia was identified as chitin. The transitional zone in the interface between the adductor muscle scar and folia are verified. The myostracum disappeared at the edge of the scar of the posterior side. From this study, the entire structure of the myostracum from the adult oyster shell of Crassostrea gigas could be proposed.

    Occurrence of professional dysphonia was analysed in a group of 309 patients treated in the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical Academy in Białystok through the period of 1999-2001. In a group of professional voice users female teachers of primary schools and lower secondary schools predominated. Obtained results were compared with those from a group of 65 persons of other occupations. In the both groups other harmful factors affecting the voice organ were excluded. The clinical assessment included subjective and objective laryngological examination using videolaryngostroboscopy. The clinical material was evaluated in a view of functional and organic disorders of the voice organ. Early occurrence and aggravation of functional changes in the larynx was recorded in non professional voice users in the course of their seniority. In professional patients organic changes were more common and occurred earlier than functional disorders. Severity of dysphonia was related to the larynx pathology, especially of a functional character.

    Two rapid, simple and sensitive extractive specrophotometric methods has been developed for the determination of anti-tussive drugs, e.g., dextromethorphan hydrobromide (DEX) and pipazethate hydrochloride (PiCl) and anti-spasmodic drugs, e.g., drotaverine hydrochloride (DvCl) and trimebutine maleate (TM) in bulk and in their pharmaceutical formulations. The proposed methods depend upon the reaction of cobalt(II)-thiocyanate (method A) and molybdenum(V)-thiocyanate ions (method B) with the cited drugs to form stable ion-pair complexes which extractable with an n-butnol-dichloromethane solvent mixture (3.5:6.5) and methylene chloride for methods A and B, respectively. The blue and orange red color complexes are determined either colorimetrically at λmax 625 nm (using method A) and 467 or 470 nm for (DEX and PiCl) or (DvCl and TM), respectively (using method B). The concentration range is 20-400 and 2.5-50 μg mL -1 for methods A and B, respectively. The proposed method was successfully applied for the determination of the studied drugs in pure and in pharmaceutical formulations applying the standard additions technique and the results obtained in good agreement well with those obtained by the official method.

    Full Text Available Spindle cell (sarcomatoid carcinoma is a rare variant of squamous cell carcinoma (SCC. It compromises of 2–3% of laryngeal cancers. Tumor arises from the oral cavity, tonsil larynx, and pharynx. Tumor is majority times misdiagnosed as reactive lesions or mesenchymal malignancies. It is considered to be a biphasic tumor that is composed of an SCC (in situ or invasive and spindle cell carcinoma (SpCC with sarcomatous appearance. In this case report, 61-year-male with minimal throat pain and acute onset dysphonia misdiagnosed and treated as a case of bronchial asthma with gastroesophageal reflux confirmed to have exophytic laryngeal growth is the cause for clinical presentation. We performed fiberoptic laryngoscopy and diagnosed to have SpCC of larynx. High index of suspicion is a must in geriatric cases with documented history of smoking and fiberoptic laryngoscopy/bronchoscopy found to be crucial in the evaluation. Histopathology expertise in surgical oncology is essential while planning treatment.

    Hepatic encephalopathy (HE) is a late complication of liver cirrhosis and is clearly associated with poor outcomes. Chronic liver insufficiency leads to progressive muscle wasting, impairing ammonia metabolism and thus increasing the risk for HE. Given the association between lean mass and adductor pollicis muscle thickness (APMT), it has been used to predict outcome and complications in many conditions, but not yet in cirrhotic patients. Therefore, this article aimed to study the association between HE manifestations and measures related to muscle mass and strength. This cross-sectional study included 54 cirrhotic outpatients with HE varying from subclinical to grade II according to the West-Haven criteria, who were submitted to neuropsychometric tests, electroencephalogram, brain Single Photon Emission Computed Tomography (SPECT), anthropometric measurements, handgrip strength (HGS) and dual energy X-ray absorptiometry exam (DXA). Multiple logistic regression analysis was performed to investigate the association between body composition measures and HE grade. Analysis of the area under the receiver operator characteristic (AUROC) curve revealed the values related to neurological manifestations (HE grades I and II). Reductions in APMT and HGS were associated with higher HE grades, suggesting a big impact caused by the loss of muscle mass and function on HE severity. The link between HE manifestations and anthropometric measures, namely APMT and HGS, point to a significant relation concerning skeletal muscles and the neurological impairment in this population.

    Extranodal lymphoma (ENL) occurs in approximately 30%–40% of all patients with non-Hodgkin lymphoma and has been described in almost all organs and tissues. However, diffuse large B-cell lymphoma is the most common histological subtype of non-Hodgkin lymphoma, primarily arising in the retroperitoneal region. In this article, we report a rare case of an adult male diagnosed with primary diffuse large B-cell lymphoma of the gluteal and adductor muscles with aggressive bone involvement. All appropriate radiological and histopathological studies were done for diagnosis and staging. After discussion with the lymphoma multidisciplinary team, it was agreed to start on R-CHOP protocol (rituximab, cyclophosphamide, doxorubicin (Adriamycin), vincristine (Oncovin®), and prednisone) as the standard of care, which was later changed to R-CODOX-M/R-IVAC protocol (rituximab, cyclophosphamide, vincristine (Oncovin®), doxorubicin, and high-dose methotrexate alternating with rituximab, ifosfamide, etoposide, and high-dose cytarabine) due to inadequate response. Due to the refractory aggressive nature of the disease, subsequent decision of the multidisciplinary team was salvage chemotherapy and autologous stem cell transplant. The aim of this case report was to describe and evaluate the clinical presentation and important radiological features of extranodal lymphoma affecting the musculoskeletal system. PMID:27398038

    Full Text Available A disfonia tem recebido um enfoque ocupacional crescente e torna-se necessário, ao otorrinolaringologista, atualizar a abordagem clínica dos trabalhadores que usam a voz como instrumento de trabalho, onde novas catagorias profissionais têm surgido e, com elas, as disfunções vocais conseqüentes às condições de trabalho. Hoje, há grandes preocupações com o prejuízo econômico e produtivo que o ditúrbio vocal possa gerar. Sabe-se que a disfunção vocal tem como característica a multicausalidade e, por isso, a avaliação, conclusão e emissão de relatórios médicos tornam-se incertos. OBJETIVO: Para melhor avaliar estes profissionais e garantir um atendimento com respaldo científico adequado, estabeleceu-se um protocolo multidisciplinar, que consiste em anamnese dirigida, exame físico, endoscopia laríngea, análise perceptiva da voz e aplicação do Voice Handicap Index (VHI. FORMA DE ESTUDO: Coorte histórica transversal. MATERIAL E MÉTODO: Para testar o uso do método, em caráter preliminar, o protocolo foi aplicado em 15 profissionais que usavam a voz para trabalhar. Então, realizou-se um estudo retrospectivo com estes pacientes. RESULTADO: Demonstrou-se que 13,3% dos profissionais apresentaram performance vocal normal; 33,3%, disfonia funcional e 46%, disfonia orgânico-funcional. A disfunção vocal foi relacionada ao exercício do trabalho em 40% dos pacientes e em 46,6% ela foi descartada.

    This study sought to compare the myoelectric activity of the hip adductors (HAs) and rectus femoris (RF) when the hip was in a neutral position or externally rotated by 30° or 50° (H0, H30, and H50, respectively) during a parallel squat. Ten healthy subjects performed 10 repetitions of squats in each of the 3 hip positions and the myoelectric activities of the HAs and RF were recorded. The signal was then divided into categories representing concentric (C) and eccentric (E) contractions in the following ranges of motion: 0-30° (C1 and E1), 30-60° (C2 and E2), and 60-90° (C3 and E3) of knee flexion. From those signals, an root mean square (RMS) value for each range of motion in each hip position was obtained. All values were normalized to those obtained during maximum voluntary isometric contraction. We found that HAs showed a significant increase in myoelectric activity during C3 and E3 in the H30 and H50 positions, as compared with H0. Meanwhile, RF activity did not significantly differ between hip positions. Both muscles showed higher activation during 60-90° (C3 and E3) of knee flexion, as compared with 0-30° (C1 and E1) and 30-60° (C2 and E2). The results suggest that if the aim is to increase HA activity despite the low percentage of muscle activation, squats should be performed with 30° of external rotation and at least 90° of knee flexion.

    Full Text Available Background: Hemifacial spasm (HS and spasmodic torticollis (ST are well-known disorders that are caused by a neurovascular conflict. HS is characterized by irregular, involuntary muscle contractions on one side of the face due to spasms of orbicularis oris and orbicularis oculi muscles, and is usually caused by vascular compression of the VII cranial nerve. ST is an extremely painful chronic movement disorder causing the neck to involuntary turn to the side, upward and/or downward. HS is usually idiopathic but it is rarely caused by a neurovascular conflict with the XI cranial nerve. Case Description: We present a case of a 36-year-old woman with a 2-year history of left hemifacial spasm and spasmodic torticollis. Pre-surgical magnetic resonance imaging MRI examination was performed with 3TMRI integrated by 3Ddrive and 3DTOF image fusion. Surgery was performed through a left suboccipital retrosigmoid craniectomy. The intraoperative findings documented a transfixing artery penetrating the facial nerve and a dominant left anteroinferior cerebellar artery (AICA in contact with the anterior surface of the pons and lower cranial nerves. Microvascular decompression (MVD was performed. Postoperative course showed the regression of her symptoms. Conclusions : Transfixing arteries are rarely reported as a cause of neurovascular conflicts. The authors review the literature concerning multiple neurovascular conflicts.

    Study Design Case report. Background Acute traumatic avulsion of the rectus abdominis and adductor longus is rare. Chronic groin injuries, often falling under the athletic pubalgia spectrum, have been reported to be more common. There is limited evidence detailing the comprehensive rehabilitation and return to sport of an athlete following surgical or conservative treatment of avulsion injuries of the pubis or other sports-related groin pathologies. Case Description A 29-year-old National Basketball Association player sustained a contact injury during a professional basketball game. This case report describes a unique clinical situation specific to professional sport, in which a surgical repair of an avulsed rectus abdominis and adductor longus was combined with a multimodal impairment- and outcomes-based rehabilitation program. Outcomes The patient returned to in-season competition at 5 weeks postoperation. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Measures such as the Copenhagen Hip and Groin Outcome Score and numeric pain-rating scale revealed progress beyond the minimal important difference. Discussion This case report details the clinical reasoning and evidence-informed interventions involved in the return to elite sport. Detailed programming and objective assessment may assist in achieving desired outcomes ahead of previously established timelines. Level of Evidence Therapy, level 4.

    Full Text Available Manila clam Ruditapes philippinarum is one of the most important economic species in shellfishery in China due to its wide geographic distribution and high tolerance to environmental changes (e.g., salinity, temperature. In addition, Manila clam is a good biomonitor/bioindicator in “Mussel Watch Programs” and marine environmental toxicology. However, there are several pedigrees of R. philippinarum distributed in the marine environment in China. No attention has been paid to the biological differences between various pedigrees of Manila clams, which may introduce undesirable biological variation in toxicology studies. In this study, we applied NMR-based metabolomics to detect the biological differences in two main pedigrees (White and Zebra of R. philippinarum and their differential responses to heavy metal exposures (Cadmium and Zinc using adductor muscle as a target tissue to define one sensitive pedigree of R. philippinarum as biomonitor for heavy metals. Our results indicated that there were significant metabolic differences in adductor muscle tissues between White and Zebra clams, including higher levels of alanine, glutamine, hypotaurine, phosphocholine and homarine in White clam muscles and higher levels of branched chain amino acids (valine, leucine and isoleucine, succinate and 4-aminobutyrate in Zebra clam muscles, respectively. Differential metabolic responses to heavy metals between White and Zebra clams were also found. Overall, we concluded that White pedigree of clam could be a preferable bioindicator/biomonitor in marine toxicology studies and for marine heavy metals based on the relatively high sensitivity to heavy metals.

    This study aimed to reveal the proteomic responses in the hepatopancreas and adductor muscle of a common biomonitor, Perna viridis after 14-day exposure to two model chemicals, cadmium (Cd; a toxic metal) and hydrogen peroxide (H{sub 2}O{sub 2}; a pro-oxidant), using two-dimensional gel electrophoresis coupled with multivariate statistical analyses. Unique sets of tissue-specific protein expression signatures were revealed corresponding to the two treatment groups. In the hepatopancreas, 15 and 2 spots responded to Cd and H{sub 2}O{sub 2} treatments respectively. 6 and 7 spots were differentially expressed in the adductor muscle for Cd and H{sub 2}O{sub 2} treatments, respectively. 15 differentially expressed spots were successfully identified by MALDI-TOF/TOF MS analysis. These proteins are involved in glycolysis, amino acid metabolism, energy homeostasis, oxidative stress response, redox homeostasis and protein folding, heat-shock response, and muscle contraction modulation. This is the first time, to have demonstrated that Cd exposure not only leads to substantial oxidative stress but also results in endoplasmic reticulum stress in hepatopancreas of the mussel. Such notable stress responses may be attributable to high Cd accumulation in this tissue. Our results suggested that investigations on these stress-associated protein changes could be used as a new and complementary approach in pollution monitoring by this popular biomonitor species.

    Introduction The study of the dynamic properties of vocal fold vibration is important for understanding the vocal production mechanism and the impact of organic and functional changes. The advent of high-speed videolaryngoscopy (HSV) has provided the possibility of seeing the real cycle of vocal fold vibration in detail through high sampling rate of successive frames and adequate spatial resolution. Objective To describe the technique, advantages, and limitations of using HSV and digital videokymography in the diagnosis of vocal pathologies. Methods We used HSV and digital videokymography to evaluate one normophonic individual and four patients with vocal fold pathologies (nodules, unilateral paralysis of the left vocal fold, intracordal cyst, and adductor spasmodic dysphonia). The vocal fold vibration parameters (glottic closure, vibrational symmetry, periodicity, mucosal wave, amplitude, and glottal cycle phases) were assessed. Results Differences in the vocal vibration parameters were observed and correlated with the pathophysiology. Conclusion HSV is the latest diagnostic tool in visual examination of vocal behavior and has considerable potential to refine our knowledge regarding the vocal fold vibration and voice production, as well as regarding the impact of pathologic conditions have on the mechanism of phonation.

    Cryptochromes are flavin- and pterin-containing photoreceptors of the cryptochrome/photolyase family. They play critical roles in organisms, among are which light-dependent and light-independent roles in biological rhythms. The present work aimed at describing a cryptochrome gene in the oyster Crassostrea gigas by (i) a characterization and phylogenetic analysis and (ii) by studying its expression in the relationship to rhythmic valve behavior in different entrainment regimes. Cryptochrome expression was focused on the adductor muscle of the oyster, the effector of the valve behavior. The results suggest involvement of Cgcry1 in oyster rhythmicity as a sensor of environmental zeitgebers, associated with circadian rhythms and potentially to tidal activity. The characterized gene belongs to type 1 cryptochrome/insect-type cry. Additionally, Cgcry1 presented a daily oscillation under L:D entrainment, which disappeared in constant darkness. Transcript expression of Cgcry1 also oscillated at tidal frequency under tidal entrainment and in constant darkness. Finally, exposure of tidally entrained oysters to saxitoxin (STX)-producing alga Alexandrium minutum induced a dose effect response in oysters by first altering Cgcry1 expression and then the behavior of oysters with increasing concentrations of toxins. This study initiates the characterization of the molecular clock in the oyster C. gigas and its interactions with environmental zeitgebers. PMID:27246263

    Full Text Available A disfonia aguda é um quadro comum na prática clínica. Seu tratamento, principalmente em adultos, não é bem definido na literatura. O corticoide é o tratamento medicamentoso mais recomendado. Os estudos existentes, entretanto, não são suficientes para a determinação da superioridade entre diferentes corticoides e a melhor forma de administração. OBJETIVO: Este estudo clínico prospectivo teve como objetivo comparar o efeito do corticoide inalatório na forma de pó seco com o efeito do corticoide oral, no tratamento da disfonia aguda. MÉTODO: Foram avaliados 32 pacientes adultos, divididos em dois grupos de 16 pacientes para cada um dos tratamentos, antes e após sete dias do uso da medicação. Os pacientes foram submetidos à videolaringosocpia e avaliação perceptiva e acústica da voz. RESULTADOS: O tratamento inalatório e oral reduziram significativamente a hiperemia, o edema e melhorou o movimento muco-ondulatório; entretanto, a redução do edema foi estatisticamente mais significativa (p = 0,012 nos pacientes tratados com a forma inalatória. A comparação dos valores da análise perceptiva auditiva e das medidas acústicas após tratamento entre os grupos, entretanto, não apresentou significância estatística.

    肌动球蛋白是扇贝闭壳肌中的主要功能蛋白质,对贝类制品的品质起关键的作用。文中以虾夷扇贝(Patinopecten yessoensis)闭壳肌为原料,提取其肌动球蛋白,并考察了热处理温度和时间对肌动球蛋白的α-螺旋含量、表面疏水性、活性-SH含量和浊度的影响。结果表明:在热处理过程中,扇贝闭壳肌肌动球蛋白的α-螺旋发生解旋,肽链展开,疏水性氨基酸残基暴露,蛋白表面疏水性增强;同时热处理使活性-SH氧化生成二硫键,蛋白聚集,使得扇贝闭壳肌肌动球蛋白的浊度增加。加热温度越高,这些指标变化越快。由此推断,扇贝闭壳肌肌动球蛋白在热处理过程中伴随着肽链的解旋和蛋白的无规则聚集。%Actomyosins are the main functional proteins of scallop adductor muscle proteins and they play a key role in the quality of shellfish products. Actomyosins were extracted from the adductor muscle of scallop (Patinopecten yessoensis). Effects of heating temperature and time on the α-helix content, surface hydrophobicity, reactive sulfhydryl content and turbidity of scallop actomyosins were investigated. The experiment results showed that in the heating process the α-helix and peptide chains unfolded, residues of hydrophobic amino acid exposed, surface hydrophobicity of protein enhanced. At the same time, heat treatment converted reactive sulfhydryl into disulfide key, proteins gath- ered together, and the turbidity increased. The changes in these parameters accelerated as heating temperature in- creased. A conclusion can be induced that the thermal denaturation process of scallop adductor muscle actomyosins was accompanied with peptide chains despiralization and random aggregation.

    The effects of spaceflight upon the "slow" muscle adductor longus were examined in rats flown in the Soviet Biosatellite COSMOS 2044. The techniques employed included standard methods for light microscopy, neural cell adhesion molecule (N-CAM) immunocytochemistry and electron microscopy. Light microscopic observations revealed myofiber atrophy and segmental necrosis accompanied by cellular infiltrates composed of macrophages, leukocytes and mononuclear cells. Neural cell adhesion molecule immunoreactivity (N-CAM-IR) was seen on the myofiber surface and in regenerating myofibers. Ultrastructural alterations included Z band streaming, disorganization of myofibrillar architecture, sarcoplasmic degradation, extensive segmental necrosis with apparent preservation of the basement membrane, degenerative phenomena of the capillary endothelium and cellular invasion of necrotic areas. Regenerating myofibers were identified by the presence of increased amounts of ribosomal aggregates and chains of polyribosomes associated with myofilaments. The principal electron microscopic changes of the neuromuscular junctions showed axon terminals with a decrease or absence of synaptic vesicles replaced by microtubules and neurofilaments, degeneration of axon terminals, vacant axonal spaces and changes suggestive of axonal sprouting. The present observations suggest that alterations such as myofibrillar disruption and necrosis, muscle regeneration and denervation and synaptic remodeling at the level of the neuromuscular junction may take place during spaceflight.

    In an explorative study the classification of a collective of patients with different voice disorders by discriminant and cluster analysis was tried. 21 variables, obtained from 128 patients with various diagnoses of voice disorders, were used. A first discriminant analysis on the basis of diagnoses-groups permitted no differentiation. A subsequent hierarchical cluster analysis indicated a four-cluster-solution. The clusters showed only little association with the phoniatric diagnoses. Cluster 1 is characterized by patients with non-organic voice disorders. Cluster 2 is marked by emotional unstable patients with organic dysphonia. Cluster 3 consists of patients with psychosomatic dysphonia by laryngeal contact granuloma, and cluster 4 contains emotional stable patients suffering from organic dysphonia and from spasmodic dysphonia. Thirteen psychological variables discriminated the clusters significantly: Anxiety about appearing in public, emotionality (neuroticism), life satisfaction, aggressiveness, anxiety, about physical injuries, extraversion.

    Objective: To improve the understanding of vertebrobasilar dolichoectasia (VBD). Methods: The clinical features,imaging findings,diagnosis,treatment and follow-up data of two cases of VBD presented with dysphagia and dysphonia were analyzed retrospectively,and the literatures were reviewed. Results; As a cerebrovascular disease,the main characteristics of VBD were the marked elongation,widening and tortuosity of the intracranial vertebral and basilar arteries. The clinical manifestations of VBD included not only cerebral ischemia or hemorrhage of brainstem,subarachnoid hemorrhage,compression symptoms of brainstem and hydrocephalus,but also dysphagia and dysphonia. The diagnosis of VBD mostly depended on imaging examinations. The treatment of VBD was still unclear,and anticoagulation therapy might be effective for some patients,but the risk of bleeding must be noticed. Conclusion: The VBD mainly presenting with dysphagia and dysphonia is easily misdi-agnosed and missed. Enough attention should be payed to this type of VBD.%目的:通过个案报告及文献复习,企盼提高对椎基底动脉延长扩张症(vertebrobasilar dolichoectasia,VBD)的认识.方法:分析2例以吞咽困难和言语含糊为主要表现的VBD患者的临床资料并复习相关文献.结果:VBD是一种以椎基底动脉的增长、增粗及扭曲为主要特点的脑血管病,其临床表现除了脑干缺血或出血、蛛网膜下腔出血、脑干压迫所引起的症状以及脑积水以外,还包括吞咽困难和言语含糊.VBD的诊断主要依靠影像学检查,目前尚无理想的治疗方法,抗凝治疗对部分患者可能有效,但有出血风险.结论:以吞咽困难和言语含糊为主要表现的VBD易被误诊和漏诊,临床医师应注意提高对VBD的认识.

    Background: Spasnodic torticollis (ST) is generally regarded as a disease affccting extrapyramidal system, but the real cause is still unknown. In addition to ordinary medical and surgical therapy, intramuscular botulinum toxin injection (IBTI) into appropriate neck muscles was considered as the first choice. However, the therapeutic efficacy is maintained limitedly and the advcrse reactions can not be well tolerated by all patients. From Au8 1992 to Aug 1999, we attemped d to treat 12 cases of ST with the therapy by injection of 50% alcohol into affected neck muscles combined with oral administration with composit dopar continually for about 4 months. All the patients had failed to respond to treatment by both westem and Chinese traditional medicine, includir g accupucture or IBTI before the trial. Methods: All twelve patinets (8 men and 4 women age range, 17 to 45 gers mean age,28.5-9.8) had suffered from the disease over 1 montth (course range, 1.2 to 1l;mean SD,4.27±3.46)before the therapy. In each case ,thee invclved neck-musles that were chosen for being injected into their moter points with 50% alcohol 2ml were among the splenius capitis trapezins and stemocleidomastoid museds on both sides The injections were performed twice a week in the first two weeks, then once to end. generally, the whole course stretching from 5 to 12 weeks(mean±11.67±2.10). At the beginning of the injections, the composit dopars were also started with low dosage, then gradually increasing till the stage in which the head jecks or tremor attenuated; or up to the highest dosage in which MModopar reached of 250, three times dayty or Sinemet CR 250, twice dayly. The duration of the medieation exterted form-12 weeks to 21 weeks(mean±s, 15.58±3.48). Resents: All thc patients experienced a temporary pain in the injecled muscles(100%,12/12) during and after shooting,but could tolerate. Drukenness lasting abont 20 munites appeared in 4 cases (33.23%,1/12)and a numbmess occurred-at a small injected area behind right ear in l,not disappearing completely till two months late. The neck moved with slight stiffness and the involuntary movement sibsided from 1 to 5 days after an injection. A few patients felt tired at the initial composit dopar therapy, which usually persisted throughout two weeks. If the oral therapy tumed ineffective. we stopped it for a week and then resumed effect would show again. These patients had been followed up for one to six years (mean±s,2.58± 1.35)since the end of their coures.The data showed what the curative rate touched 66.7% (8/12),relieved 8.3%(l/12),ineffective 33.3%(4/12) and the overall effective 75%. Discussion: 50% alcohol injection into monar point in a muscle was induced by Okubo and Yanagisawa, which was used to relieve the low limb extensor spasn. It was assumed that the injection might influence the Ia afferent impulses among a motor neuron, Rensaw's cell,agonist and atagonist, which can inhibit muscular spasm without myasthenia. We tried to use this mechanism for improving the neck myospasm though the later may be different from the former. Furthermore we attempted to increase the level of dopamin in the brain to make balance of netturotransitter in certain area of central nervous system,especially in the extrapyramidal one. Although the therapy with BT is decleared effective,the curative durafion can generally maintain from one to tree monthas. Moreover there may be some serious side effects:fatigoe-local pain, dysphagia,neck weakness, upper cstremity weakness or numbness and hoarseness. Condusion: The preliminary outcome demonstrates that injection with 50% alcohol combined with oral medication with composit dopar ia a effective therapy for ST without serious side effect. When the effectiveness attenuated in the oral course,never abandon it, stop for a week, then resume and there may be a dramatic improvement except the course that has been over six months.

    The following factors besides spasm and contraction of the adductor muscles contribute to the occurrence of dislocations of the hip in spastic paralysis: Spasm and contraction of the iliopsoas muscle and enhanced valgus position and antetorsion. The author holds the opinion that in case of malformation of the proximal end of the femur, it is not only the indirect action of the spastic musculature via the proximal femur-epiphyseal cartilage which is responsible for this phenomen in accordance with the law on functional adaption through longitudinal growth (Pauwels), but also the direct traction of the iliopsoas tendon. A clue in this direction is the often very pronounced elongation or enlargement of the trochanter minor. The author demonstrates the pathogenetic importance of iliopsoas contracture and malpositioning of the neck of the femur by means of analyses of the course in two patients. The following principles of treatment are postulated for spastic dislocation of the hip: Elimination of the pathogenetic factors through myotenotomy of the adductor muscles and complete resection of the obturator nerve, with observation of strict aftertreatment criteria, tenotomy of the iliopsoas, repositioning and osteotomy with turning into varus. Osteotomy without previous elimination of the pathogenetically acting muscular forces does not appear useful. Likewise, permanent re-positioning by means of muscle-relaxing operation cannot be sufficiently safe-guarded without additional osteotomy once the dislocation has taken place. In twelve patients with spastic dislocation of the hip, treated in accordance with these guidelines (two without osteotomy) aged 6 6/12 and 19 5/12 years, a roentgenologically good result was obtained in half of the cases, whereas the functional result was satisfactory not only with these patients but also with part of the other patients. If surgical treatment is instituted early enough, and if the experiences described here are taken into consideration

    Objective To compare adductor canal block with femoral nerve block under multimodal analgesia for early analgesic effect and rehabilitation after total knee replacement (TKA). Methods Eighty patients who were scheduled to undergo TKA were randomly divided into two groups:adductor canal block (ACB) group and femoral nerve block (FNB) group. All the pa⁃tients were given Celecoxib (200 mg, bid) three days preoperative. The ACB group was given adductor canal block with ropivacaine (5 g/L, 20 ml) and 0.1 mg epinephrine half an hour before the surgery. The FNB group was given femoral nerve block with ropivacaine (3.33 g/L, 30 ml) and 0.1 mg epinephrine half an hour before the surgery. Both of the two groups were given local infiltration analge⁃sia with ropivacaine (2.5 g/L, 20 ml) and 0.1 mg epinephrine after click into the prosthesis. After surgery, all the patients were given Diclofenac Sodium (50 mg, q12h, p.o.), oxycodone hydrochloride sustained⁃release tablets (10 mg, q12 h, p.o.) and Parecoxib (40 mg, q12 h, i.m.) until discharged. The resting and motion Numeric Rating Scales (NRS) scores, the knee joint range of motion, the muscle strength of quadriceps femoris, total Meperidine hydrochloride consumption, postoperative hospital stay and the side effects and complications were recorded. Results The resting and motion NRS scores were similar to the ACB group of FNB group which were not statistically significant. The range of motion (1, 2, 3 days after surgery) and muscular strength of quadriceps femofis (within 24 hours) in the ACB group was better than in the FNB group. The average length of postoperative hospital stay was shorter in the ACB group than it was in FNB group. In the ACB group the range of motion at 14 day, total Meperidine hydrochloride con⁃sumption and the side effects were similar to the FNB group. Conclusion Under multimodal analgesia, the adductor canal block had similar early analgesia effects with the femoral nerve block when TKA was

    The effects of spaceflight upon the 'slow' muscle adductor longus was examined in rats flown in the Soviet Biosatellite COSMOS 2044. Three groups - synchronous, vivarium and basal served as controls. The techniques employed included standard methods for light microscopy, N-CAM immunocytochemistry and electron microscopy. Light microscopic observations revealed myofiber atrophy, contraction bands and segmental necrosis accompanied by cellular infiltrates composed of macrophages, leucocytes and mononuclear cells. N-CAM immunoreactivity was seen (N-CAM-IR) on the myofiber surface, satellite cells and in regenerating myofibers reminiscent of myotubes. Ultrastructural alterations included Z band streaming, disorganization of myofibrillar architecture, sarcoplasmic degradation, extensive segmental necrosis with preservation of the basement membrane, degenerative phenomena of the capillary endothelium and cellular invasion of necrotic areas. Regenerating myofibers were identified by the presence of increased amounts of ribosomal aggregates and chains of polyribosomes associated with myofilaments that displayed varied distributive patterns. The principal electron microscopic changes of the neuromuscular junctions consisted of a decrease or absence of synaptic vesicles, degeneration of axon terminals, increased number of microtubules, vacant axonal spaces and axonal sprouting. The present observations indicate that major alterations such as myofibrillar disruption and necrosis, muscle regeneration and denervation and synaptic remodeling at the level of the neuromuscular junction may take place during spaceflight.

    Full Text Available This study describes preliminary laryngeal electromyography (LEMG data and botulinum toxin treatment in patients with dysphonia due to movement disorders. Twenty-five patients who had been clinically selected for botulinum toxin administration were examined, 19 with suspected laryngeal dystonia or spasmodic dysphonia (SD, 5 with vocal tremor, and 1 with Gilles de la Tourette syndrome (GTS. LEMG evaluations were performed before botulinum toxin administration using monopolar electrodes. Electromyography was consistent with dystonia in 14 patients and normal in 5, and differences in frequency suggesting essential tremor in 3 and Parkinson tremors in 2. The different LEMG patterns and significant improvement in our patients from botulinum toxin therapy has led us to perform laryngeal electromyography as a routine in UNICAMP movement disorders ambulatory.

    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.

    BACKGROUND: Selective posterior rhizotomy has been extensively acknowledged as an effective method of relieving lower limb spasticity in cerebral palsy. However, the postoperative complications such as reduced muscle strength and imbalance of the spine are of concern among surgeons and therapists. The combination of limited selective posterior rhizotomy (LSPR) with adductor tenotomy can decrease these complications without compromising the treatment effects.OBJECTIVE: To investigate the effects of combination therapy of LSPR with adductor tenotomy on lower limb spasticity, gait and movement of the patients.DESIGN: A self-controlled trial and observational follow-up taking children with cerebral palsy as the subjects.SETTING: Orthopedic Department of First Hospital Affiliated to Dalian Medical University.PARTICIPANTS: Thirty children patients with cerebral palsy treated in the Orthopedics Department of the First Affiliated Hospital of Jilin University from January 2001 to December 2002 were recruited in this trial. They presented scissors gait, flexed knee and tiptoeing of different degree. There were 18 cases of brisk tendon reflex and ankle clonus, and 15 cases of positive Babinski' s sign. All the patients had no immobile soft tissue contracture and could either accomplish walking and crouching independently or walk with arms on assistant devices.INTERVENTIONS: The patients received LSPR of L5 and S1 dorsal roots together with bilateral adductor tenotomy. Muscle tone and strength, knee and Achilles tendon reflexes, ankle clonus and pathologic signs were recorded before and after operation. X-ray examination on lumbar spine and pelvic was also taken for detection of deformity. The patients' movements were assessed according to their standing and walking postures, standing and crouching movements before operation and on follow-up. During follow-up all the mentioned indices were recorded by reference to the original case history, hospital reexamination and

    Cat scratch disease is caused by Bartonella henselae, a bacterium transmitted to humans from cats through a scratch or by fleas. In 90% of cases, the clinical presentation is that of classical cat scratch disease where an adjacent lymph node is infected. Atypical manifestations include prolonged fever, liver and spleen abscesses, infective endocarditis, central nervous system involvement etc. We present a 6 years old girl who suffered from L2 vertebral osteomyelitis and epidural abscess, initially presenting as colic left waist pain, with no back pain or high fevers. During the process of diagnosis, she recovered without surgical intervention or antibiotic treatment. A review of the literature indicates that among the wide spectrum of clinical manifestations of cat scratch disease, skeletal involvement is rare. However, in cases of osteomyelitis, vertebrae are a common site as well as formation of a contiguous phlegmon. Although no studies have investigated the efficacy of different treatment regimens, all patients presented were treated with antimicrobial combinations and recovery rates were high. In view of the patient presented here, it is questioned whether the high recovery rates are a result of efficient antibiotic treatment or due to a benign natural course of the disease.

    We formulate the problem of the late accretion phase of the evolution of an isothermal magnetic disk surrounding a forming star. The evolution is described by the six-fluid MHD equations, accounting for the presence of neutrals, atomic and molecular ions, electrons, and neutral, positively, and negatively charged grains. Only the electron fluid is assumed to be attached to the magnetic field, in order to investigate the effect of the detachment of the ions from the magnetic field lines that begins at densities as low as 10^8 cm^-3. The "central sink approximation" is used to circumvent the problem of describing the evolution inside the opaque central region for densities greater than 10^11 cm^-3. In this way, the structure and evolution of the isothermal disk surrounding the forming star can be studied at late times without having to implement the numerically costly radiative transfer required by the physics of the opaque core. The mass and magnetic flux accumulating in the forming star arecalculated , as are...

    1989-02-17

    Two voice disorders long considered to be psychological problems, stuttering and spasmodic dysphonia, have been shown in many persons to have a neurophysiological basis. Investigators at the 155th national meeting of the American Association for the Advancement of Science, in San Francisco, described their findings, which are based on new analytic techniques. The research is being done at the Dallas Center for Vocal Motor Control, Callier Center for Communication Disorders, University of Texas at Dallas Health Science Center. The technology employed to learn what's wrong with the brains, rather than the psyches, of persons with certain speech disorders includes magnetic resonance imaging (MRI), brain electrical activity mapping (BEAM), and single photon emission computerized tomography (SPECT). The results of applying these techniques are combined with quantitative behavioral measures of vocal and nonvocal motor control, language performance, and cognition to arrive at a better understanding of the problem.

    Full Text Available Abstract Background Although the c.904_906delGAG mutation in Exon 5 of TOR1A typically manifests as early-onset generalized dystonia, DYT1 dystonia is genetically and clinically heterogeneous. Recently, another Exon 5 mutation (c.863G>A has been associated with early-onset generalized dystonia and some ΔGAG mutation carriers present with late-onset focal dystonia. The aim of this study was to identify TOR1A Exon 5 mutations in a large cohort of subjects with mainly non-generalized primary dystonia. Methods High resolution melting (HRM was used to examine the entire TOR1A Exon 5 coding sequence in 1014 subjects with primary dystonia (422 spasmodic dysphonia, 285 cervical dystonia, 67 blepharospasm, 41 writer's cramp, 16 oromandibular dystonia, 38 other primary focal dystonia, 112 segmental dystonia, 16 multifocal dystonia, and 17 generalized dystonia and 250 controls (150 neurologically normal and 100 with other movement disorders. Diagnostic sensitivity and specificity were evaluated in an additional 8 subjects with known ΔGAG DYT1 dystonia and 88 subjects with ΔGAG-negative dystonia. Results HRM of TOR1A Exon 5 showed high (100% diagnostic sensitivity and specificity. HRM was rapid and economical. HRM reliably differentiated the TOR1A ΔGAG and c.863G>A mutations. Melting curves were normal in 250/250 controls and 1012/1014 subjects with primary dystonia. The two subjects with shifted melting curves were found to harbor the classic ΔGAG deletion: 1 a non-Jewish Caucasian female with childhood-onset multifocal dystonia and 2 an Ashkenazi Jewish female with adolescent-onset spasmodic dysphonia. Conclusion First, HRM is an inexpensive, diagnostically sensitive and specific, high-throughput method for mutation discovery. Second, Exon 5 mutations in TOR1A are rarely associated with non-generalized primary dystonia.

  1. Temporal discrimination thresholds in adult-onset primary torsion dystonia: an analysis by task type and by dystonia phenotype.

    2012-01-01

    Adult-onset primary torsion dystonia (AOPTD) is an autosomal dominant disorder with markedly reduced penetrance. Sensory abnormalities are present in AOPTD and also in unaffected relatives, possibly indicating non-manifesting gene carriage (acting as an endophenotype). The temporal discrimination threshold (TDT) is the shortest time interval at which two stimuli are detected to be asynchronous. We aimed to compare the sensitivity and specificity of three different TDT tasks (visual, tactile and mixed\\/visual-tactile). We also aimed to examine the sensitivity of TDTs in different AOPTD phenotypes. To examine tasks, we tested TDT in 41 patients and 51 controls using visual (2 lights), tactile (non-painful electrical stimulation) and mixed (1 light, 1 electrical) stimuli. To investigate phenotypes, we examined 71 AOPTD patients (37 cervical dystonia, 14 writer\\'s cramp, 9 blepharospasm, 11 spasmodic dysphonia) and 8 musician\\'s dystonia patients. The upper limit of normal was defined as control mean +2.5 SD. In dystonia patients, the visual task detected abnormalities in 35\\/41 (85%), the tactile task in 35\\/41 (85%) and the mixed task in 26\\/41 (63%); the mixed task was less sensitive than the other two (p = 0.04). Specificity was 100% for the visual and tactile tasks. Abnormal TDTs were found in 36 of 37 (97.3%) cervical dystonia, 12 of 14 (85.7%) writer\\'s cramp, 8 of 9 (88.8%) blepharospasm, 10 of 11 (90.1%) spasmodic dysphonia patients and 5 of 8 (62.5%) musicians. The visual and tactile tasks were found to be more sensitive than the mixed task. Temporal discrimination threshold results were comparable across common adult-onset primary torsion dystonia phenotypes, with lower sensitivity in the musicians.

    Laryngeal dystonia is a movement disorder of the muscles within the larynx, which most commonly manifests as spasmodic dysphonia (SD). Rarer reported manifestations include dystonic respiratory stridor and dyscoordinate breathing. Laryngeal dystonia has been treated successfully with botulinum neurotoxin (BTX) injections since 1984. We reviewed prospectively collected data in a consecutive series of 193 patients with laryngeal dystonia who were seen at St. Vincent's Hospital between 1991 and 2011. Patient data were analyzed in Excel, R, and Prism. Laryngeal dystonia manifested as SD (92.7%), stridor (11.9%), dystonic cough (6.2%), dyscoordinate breathing (4.1%), paroxysmal hiccups (1.6%), and paroxysmal sneezing (1.6%). There were more women (68.4%) than men (31.6%), and the average age at onset was 47 years. A positive family history of dystonia was present in 16.1% of patients. A higher incidence of extra-laryngeal dystonia (ie, torticollis and blepharospasm) and concurrent manifestations of laryngeal dystonia were present in patients with dystonic cough, dyscoordinate breathing, paroxysmal sneezing, and hiccups than in other patients (P = 0.003 and P Technical failures were rare (1.1%). Dysphonia secondary to vocal cord paresis followed 38.7% of treatments.

    Full Text Available We report a rare case of neurodegeneration with brain iron accumulation (NBIA presented with episodic inspiratory stridor. A 10-year-old boy presented with 3-year history of gradually progressive spastic gait and generalized dystonia (involving all four limbs, neck, jaw, and speech. MRI brain showed "Eye of Tiger" sign. He recently developed severe inspiratory stridor associated with almost gasping respiration. Direct video laryngoscopy showed paradoxical vocal cord closure during inspiration. He was treated with EMG-guided botulinum toxin-A injection given into bilateral thyroarytenoid muscles, resulting in dramatic response with complete disappearance of the stridor within a week. The effect lasted 18 months.

    Objetivo: Examinar la frecuencia con que se presentan lesiones orgánicas benignas de las cuerdas vocales (LOB-CV) entre los pacientes diagnosticados de disfonía funcional (DF) y explorar sus asociaciones con el desempeño de un trabajo como usuario profesional de la voz (UPV). Métodos: Estudio realizado en una serie de 132 pacientes diagnosticados de DF. Las LOB-CV se objetivaron mediante fibrolaringoscopia. Se documentaron la ocupación, variables sociodemográficas y factores de riesgo no ocupacionales. Se realizó un análisis descriptivo de la muestra, que se estratificó por las variables de exposición laboral (UPV y no-UPV) y por sexo. Se exploraron las asociaciones bivariadas entre la presencia de LOB-VC y el resto de variables. Se utilizó el paquete estadístico SPSS versión 15. Resultados: Los pacientes fueron principalmente mujeres (58,3%), con una edad media de 48 años (DE±13). Un 40% eran usuarios profesionales de la voz (UPV). El 47% presentaron alguna LOB-CV, siendo la más prevalente los pólipos/nódulos (29%). Los UPV con disfonía funcional presentaron mayor prevalencia de LOB-CV (57%) frente a los no-UPV (40%). Ser UPV se asoció a mayor riesgo de padecer LOB-CV (odds ratio de prevalencia cruda, ORPc=1,48; IC95%=0,74- 2,98), principalmente pólipos/nódulos (ORPc=1,77; IC95%=0,82-3,78) y laringitis crónica (ORPc= 2,31; IC95%=0,37- 14,32), aunque sin alcanzar significación estadística. Fumar se asocio significativamente a mayor riesgo de presentar pólipos/nódulos en todos los pacientes (ORPc=2,95; IC95%=1,33-6,53). Conclusiones: Ser trabajador UPV se asoció a un mayor riesgo de LOB-CV, principalmente pólipos/nódulos de las cuerdas vocales y laringitis crónica. Los servicios de prevención deberían evaluar este riesgo laboral siempre que la voz sea una herramienta de trabajo primaria, con el fin de poder establecer medidas preventivas precoces.

  11. Non-organic dysphonia. II. Phonetograms for normal and pathological voices.

    1988-01-01

    The clinical usefulness of the phonetogram, i.e. a graph showing the sound pressure level (SPL) of softest and loudest possible phonation over the entire fundamental frequency range of a voice, was investigated. Phonetograms of 29 female non-organic dysphonic patients, 17 healthy female subjects, 18 non-organic dysphonic male patients and 12 healthy male subjects were compared. The female patients showed significantly lower SPL values for loudest phonation when compared with healthy female subjects, while no significant difference was seen in the male subjects in this regard. With respect to the SPL values for softest phonation, on the other hand, the male dysphonic patients showed significantly higher SPL values than the healthy male subjects, whereas no significant difference was seen in the female subjects. Spectrum analysis showed that the patients had a more dominating fundamental in loud phonation than did the healthy voices.

    1991-01-01

    R. L. was a 52-year-old man who was referred for an SLP consultation to determine the nature of his fluency disorder, whether or not treatment would be beneficial, and finally whether resumption of pre-trauma vocational status was feasible. The patient was involved in a motor vehicle accident with no resulting detectable trauma. However, shortly after the accident, R. L. developed a severe dysfluency that was later described as cortical stuttering. We reviewed the medical and rehabilitation work-up that attempted to determine whether the communication disorder was functional or organic in origin. Once the fluency disorder was determined to be caused by a suspected small, focal, hemispheric lesion, a five-month treatment program was undertaken that used a noval prosthetic approach to restore fluency. Once fluency was restored with the use of an artificial larynx, a residual anomia was detected and treated. The case of R. L. illustrates a stuttering that appeared to be caused by a combined neurogenic dyspraxic (vocal control), dysarthric (motor control), and dysnomic (word-finding) dysfluency. The literature on this issue was reviewed and the underlying mechanism of recovery was discussed.

    Full Text Available Introduction: Foreign bodies in the upper airway are one of the most challenging otolaryngology emergencies and have various presentations depending on their physical properties and location. Leeches are blood-sucking hermaphroditic worms that vary in color, length, and shape. They usually reside in fresh-water streams and lakes. When rural untreated water is drunk, leeches may localize in the nose, pharynx, and esophagus, or rarely in the larynx. CaseReport: This case is a man who was referred to our otolaryngology clinic with a complaint of hemoptysis and mild respiratory distress. The patient’s symptoms were all relieved post operatively and he was discharged on the second day following the procedure.     Conclusion: Leeches should be suspected as an airway foreign body in patients with a recent history of drinking stream water.

  19. Thalamic Volume Is Reduced in Cervical and Laryngeal Dystonias.

    Directory of Open Access Journals (Sweden)

    Jeff L Waugh

    Full Text Available Dystonia, a debilitating movement disorder characterized by abnormal fixed positions and/or twisting postures, is associated with dysfunction of motor control networks. While gross brain lesions can produce secondary dystonias, advanced neuroimaging techniques have been required to identify network abnormalities in primary dystonias. Prior neuroimaging studies have provided valuable insights into the pathophysiology of dystonia, but few directly assessed the gross volume of motor control regions, and to our knowledge, none identified abnormalities common to multiple types of idiopathic focal dystonia.We used two gross volumetric segmentation techniques and one voxelwise volumetric technique (voxel based morphometry, VBM to compare regional volume between matched healthy controls and patients with idiopathic primary focal dystonia (cervical, n = 17, laryngeal, n = 7. We used (1 automated gross volume measures of eight motor control regions using the FreeSurfer analysis package; (2 blinded, anatomist-supervised manual segmentation of the whole thalamus (also gross volume; and (3 voxel based morphometry, which measures local T1-weighted signal intensity and estimates gray matter density or volume at the level of single voxels, for both whole-brain and thalamus.Using both automated and manual gross volumetry, we found a significant volume decrease only in the thalamus in two focal dystonias. Decreases in whole-thalamic volume were independent of head and brain size, laterality of symptoms, and duration. VBM measures did not differ between dystonia and control groups in any motor control region.Reduced thalamic gross volume, detected in two independent analyses, suggests a common anatomical abnormality in cervical dystonia and spasmodic dysphonia. Defining the structural underpinnings of dystonia may require such complementary approaches.

  20. Clinical use of non-A botulinum toxins: botulinum toxin type B.

    Science.gov (United States)

    Dressler, D; Eleopra, R

    2006-04-01

    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. In BT-B the relationship between autonomic and motor effects known from BT-A is substantially shifted towards autonomic effects. BT-B, therefore, should be used carefully in patients with autonomic disorders and in patients with concomitant anticholinergic therapy. If NeuroBloc/MyoBloc is used to treat cervical dystonia patients with antibody-induced failure of BT-A therapy, 86% of those will develop complete secondary therapy failure after five applications. If NeuroBloc/MyoBloc used to treat cervical dystonia patients without prior exposure to BT, 44% of those will develop complete secondary therapy failure after nine applications. NeuroBloc/MyoBloc, therefore, is associated with substantial antigenicity problems originating from a particular low specific biological potency. Systemic anticholinergic adverse effects and high antigenicity limits the clinical use of NeuroBloc/MyoBloc considerably. PMID:16785108

  1. Sporadic adult onset primary torsion dystonia is a genetic disorder by the temporal discrimination test.

    LENUS (Irish Health Repository)

    Kimmich, Okka

    2012-02-01

    Adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance; patients with sporadic adult-onset primary torsion dystonia are much more prevalent than familial. The temporal discrimination threshold is the shortest time interval at which two stimuli are detected to be asynchronous and has been shown to be abnormal in adult-onset primary torsion dystonia. The aim was to determine the frequency of abnormal temporal discrimination thresholds in patients with sporadic adult-onset primary torsion dystonia and their first-degree relatives. We hypothesized that abnormal temporal discrimination thresholds in first relatives would be compatible with an autosomal dominant endophenotype. Temporal discrimination thresholds were examined in 61 control subjects (39 subjects <50 years of age; 22 subjects >50 years of age), 32 patients with sporadic adult-onset primary torsion dystonia (cervical dystonia n = 30, spasmodic dysphonia n = 1 and Meige\\'s syndrome n = 1) and 73 unaffected first-degree relatives (36 siblings, 36 offspring and one parent) using visual and tactile stimuli. Z-scores were calculated for all subjects; a Z > 2.5 was considered abnormal. Abnormal temporal discrimination thresholds were found in 1\\/61 (2%) control subjects, 27\\/32 (84%) patients with adult-onset primary torsion dystonia and 32\\/73 (44%) unaffected relatives [siblings (20\\/36; 56%), offspring (11\\/36; 31%) and one parent]. When two or more relatives were tested in any one family, 22 of 24 families had at least one first-degree relative with an abnormal temporal discrimination threshold. The frequency of abnormal temporal discrimination thresholds in first-degree relatives of patients with sporadic adult-onset primary torsion dystonia is compatible with an autosomal dominant disorder and supports the hypothesis that apparently sporadic adult-onset primary torsion dystonia is genetic in origin.

  2. Art and dystonia.

    2015-09-15

    Dystonia has a recent history in medicine. Focal dystonia was described in the 19th century by classic authors including Gowers, whilst generalized dystonia was described at the turn of the century. However, it is possible to find precise descriptions of dystonia in art, centuries before the medical definition. We have reviewed several pieces of art (sculpture, painting and literature) across the history that might represent descriptions of dystonia, from ancient period to nowadays. In classic times, the first reference to abnormal postures can be tracked back to the new Empire of Egypt (equinus foot), not to mention some recently described examples of dystonia from the Moche sculptures in Peru or Veracruz culture from Mexico. In Middle Ages it is possible to find many examples of sculptures in European cathedrals representing peasants with dramatic, presumably dystonic postures that coexist with amputation of limbs. This unique combination of dystonia and limb amputation probably represents ergotism. The painters Brueghel, Ribera and Velazquez also represented figures with postures likely to be dystonic. Literature is also a source of precise pre-neurological descriptions, especially during the 19th century. In David Copperfield, Dickens depicts characters with generalized dystonia (Uriah Heep), cervical dystonia (Mr. Sharp) and spasmodic dysphonia (Mr Creakle). Finally, even in modern Art (19th and 20th centuries), there are dramatic descriptions of abnormal postures that are likely to be dystonic, such as painful cervical dystonia (Brancusi), cervical dystonia with sensory trick (Modigliani) and upper limb dystonia (Wyspianski). However some postures presented in works of art may simply be a form of artistic expression and only bear unintentional resemblance to the dystonic postures. Art may be a source of neurological information, and that includes primary and secondary dystonia. PMID:26139341

No relation was found between patient's gender and spectrographic improvement. Regarding diagnoses, differences caused by therapy were only significant for spectrogram regularity. CONCLUSIONS: Not all evaluated parameters showed significant improvements with therapy, however, acoustic spectrography proved to be an efficient tool to evaluate patients' progresses during vocal rehabilitation, complementing auditory-perceptual evaluation and composing a multidimensional assessment protocol.

    Conclusion: Traumatic manifestations of the laryngeal structures that occur during intubation are the most common causes of postoperative dysphonia, with a tendency toward a regressive course of the resulting dysphonia. As such, it is important to establish an early diagnosis and adopt preventive measures.

  14. Psychogenic voice disorders and traumatic stress experience: a discussion paper with two case reports.

    Science.gov (United States)

    Baker, Janet

    2003-09-01

    Psychogenic dysphonia refers to loss of voice where there is insufficient structural or neurological pathology to account for the nature and severity of the dysphonia, and where loss of volitional control over phonation seems to be related to psychological processes such as anxiety, depression, conversion reaction, or personality disorder. Such dysphonias may often develop post-viral infection with laryngitis, and generally in close proximity to emotionally or psychologically taxing experiences, where "conflict over speaking out" is an issue. In more rare instances, severe and persistent psychogenic dysphonia may develop under innocuous or unrelated circumstances, but over time, it may be traced back to traumatic stress experiences that occurred many months or years prior to the onset of the voice disorder. In such cases, the qualitative nature of the traumatic experience may be reflected in the way the psychogenic voice disorder presents. The possible relationship between psychogenic dysphonia and earlier traumatic stress experience is discussed, and the reportedly low prevalence of conversion reaction (4% to 5%) as the basis for psychogenic dysphonia is challenged. Two cases are presented to illustrate the issues raised: the first, a young woman who was sexually assaulted and chose to "keep her secret," and the second, a 52-year-old woman who developed a psychogenic dysphonia following a second, modified thyroplasty for a unilateral vocal fold paresis.

The emotional scores were the highest in spasmodic dysphunia, and followed by functional dysphoina. In another group, the physical scores were higher than functional scores and emotional scores. Treatment resulted in statistical improvement in VHI scores (P<0.05). The total scores were different significantly between different educational background and age groups(F from 8.701 to 27. 371, P=0.000). The higher the educational degree, the higher the VHI scores. As to age groups, the juvenile group' s scores were the lowest, while the youth' s group the highest, then the scores declined when ages increased. Conclusion As a useful supplementary instrument to measure the voice disorder severity and the treatment' s effect, VHI can comprehensively assess the voice handicap' s affect to the life quality and the difference after the treatment, especially in physical, functional and emotional aspects, but it is somehow subject to the educational degree and age.

    2004-05-01

    Analysis of professional dysphonia in 309 patients treated in Phoniatric Outpatient Clinic of the (chair and) Department of Otolaryngology AM in Bialystok was performed. The teachers of primary and lower secondary schools were the majority of the patients. The teachers were compared with the 65 patients of other occupations. Additional harmful factors were excluded in both groups. In all patients' otolaryngologic, phoniatric and videostroboscopic examinations were completed. The analysis paid attention to functional and organic dysphonias. In the group of voice workers there were found early functional laryngeal disorders, which were progressive with the period of work. In other patients organic disorders were more common and occurred earlier than functional ones. The degree of dysphonia depended on laryngeal pathology, especially in case of functional dysphonia.

    We reviewed the clinical records of 62 patients with voice disorders without organic diseases of the larynx who were examined in the Department of Otolaryngology, Kurume University Hospital during the 10 years from 1971 to 1980. There were 9 patients with psychogenic dysphonia, 24 with vocal abuse, 4 with spastic dysphonia, 9 with mutational voice disturbance, 8 with virilization of voice, 7 with dysphonia attributed to diseases of other organs than the larynx, and 1 with senile change of voice. The clinical service to the patients with these kinds of dysphonia has been poor in Japan for lack of trained voice pathologists. This has been also the case with our department. Recognition for the necessity of voice pathologists is strongly demanded.

  1. [Differential diagnosis of hoarseness].

    Science.gov (United States)

    Voigt-Zimmermann, S; Lampe, K; Arens, C

    2014-04-01

    Hoarseness can be the leading symptom of dysphonia. In combination with impaired vocal performance and subjective voice-related discomfort, it can represent an individually different handicap for patients and lead to limited participation in social and professional life. Since the reasons for dysphonia may be not only functional but also organic with a potentially poor prognosis, hoarseness must be clarified using differential diagnosis. In addition to the knowledge of possible diseases, pathogenesis, and treatment options for dysphonia, the differential diagnostic approach requires profound knowledge of the various diagnostic methods, and of the interpretation of the results in particular. The etiology of dysphonia is very diverse and rarely monocausal. Therefore, a team-based and interdisciplinary differential diagnostic approach is recommended.

    2012-11-01

    Full Text Available Background: Laryngeal videostroboscopy is an important noninvasive diagnostic tool in patients with dysphonia. More than 50% of patients with dysphonia have a benign laryngeal lesion on vocal fold examination. The aim of this study was to evaluate patients with benign laryngeal lesions by videostroboscopy.Methods: This cross-sectional study was done on 159 patients with dysphonia in Amiralam Hospital in Tehran, Iran during 2006-2007. All the patients underwent stroboscopic examination of the vocal folds, including their movement. We also evaluated the patients for mucosal status, mucosal wave and patterns of glottal closure.Results: Eighty-two patients participating in the study were female and 77 were male. Reflux laryngitis and muscle tension dysphonia were the most observed disorders in the patient population. Patients with sulcus vocalis and intracordal cysts had the worst mucosal wave patterns.Conclusion: Laryngeal videostroboscopy is a useful tool for the diagnosis and treatment planning in patients with benign laryngeal lesions.

  3. EMG analysis of the lower extremities during pitching in high-school baseball.

    Science.gov (United States)

    Yamanouchi, T

    1998-01-01

    I evaluated the contractions of the muscles of the lower extremities during baseball pitching using video imaging and simultaneous surface EMG. The subjects were 10 members of a high school baseball club and, for contrast, 10 students without any baseball club experience. I divided their pitching movements into two phases determined with respect to the landing of the non-pivot leg. The EMG signal intensities over the 2 seconds prior to landing, and over the 2 seconds after landing, were then integrated to give an EMG value to each phase. I then computed this value as the % MMT. The abductor and adductor of the hip muscles of both lower extremities in the players were strongly contracted, especially the adductor. This finding was consistent with the observation that pitching tends to lead to adductor muscle disorders. Strengthening the adductor and its antagonist abductor can therefore directly influence the capability for pitching, and can reduce the risk for the adductor disorders. PMID:9658746

  11. Homology of the jaw muscles in lizards and snakes-a solution from a comparative gnathostome approach.

    Science.gov (United States)

    Johnston, Peter

    2014-03-01

    Homology or shared evolutionary origin of jaw adductor muscles in lizards and snakes has been difficult to establish, although snakes clearly arose within the lizard radiation. Lizards typically have temporal adductors layered lateral to medial, and in snakes the muscles are arranged in a rostral to caudal pattern. Recent work has suggested that the jaw adductor group in gnathostomes is arranged as a folded sheet; when this theory is applied to snakes, homology with lizard morphology can be seen. This conclusion revisits the work of S.B. McDowell, J Herpetol 1986; 20:353-407, who proposed that homology involves identity of m. levator anguli oris and the loss of m. adductor mandibulae externus profundus, at least in "advanced" (colubroid) snakes. Here I advance the folded sheet hypothesis across the whole snake tree using new and literature data, and provide a solution to this homology problem.

    Transfemoral amputations with more proximal amputation levels have the problem of secondary development into flexion and abduction contractures. This is induced by muscle imbalance, especially the loss of adductor muscle insertions when abductor muscle insertions are preserved. This causes considerable problems when fitting prosthetics. Myodesis with insertion of the distally detached adductor magnus muscle to the lateral femoral cortex, introduced here, results in a stronger stump with good muscle balance, and prosthetics fitting is significantly improved.

    Helmi, C; Cracraft, J

    1977-07-01

    This study was designed to investigate the growth patterns of three hindlimb muscles of the chicken relative to the functional-biomechanical demands of increasing body size. The biceps femoris, a bipennate non-postural muscle, grew relatively faster in terms of wet and dry weight than did the parallel-fibred adductor superficialis or the unipennate adductor profundus, both postural muscles. All three muscles exhibited positive allometry (relative to body weight) in muscle length but only biceps femoris and adductor profundus showed positive allometry in cross sectional area adductor superficialis having isometric growth in this parameter. In biceps femoris and adductor superficialis the lengths of the longest and shortest fasciculi grew at equal rates, whereas in adductor profundus the shortest fasciculi grew faster than the longest. We conclude that muscle weight alone is an insufficient indicator of changing function in growing muscle. Hence, growth studies should include other functionally relevant parameters such as cross sectional area, which is proportional to the force-producing capabilities of the muscle, or fibre (fasciculus) length, which is indicative of the absolute amount of stretching or shortening that is possible and of the contraction velocity.

    In this study, structure and validity of the German version of the Voice-Related Quality of Life (V-RQOL) questionnaire and its correlation to age, gender, and type of dysphonia (organic vs. functional) were assessed. Correlations of the V-RQOL result on the one hand and emotional and physical complaints on the other hand were investigated. Data were collected in 62 adult patients with dysphonia of benign origin and the following results were found: the German version of the V-RQOL questionnaire describes voice-related quality of life in one single value. Age, gender and type of dysphonia do not influence its result. Dysphonic patients present with an increased number of emotional and physical complaints when compared with normative values derived from the literature. However, not all of these complaints correlate with voice-related quality of life at a significant level.

    1998-08-01

    The aim of this study was to determine the relationship between glottic space and breathy voice. Using a new computerized method of analysing the glottic area of video images with the Vocim computer system, 16 patients with a vocal cord palsy and 31 with non-organic dysphonia were examined. The quality of the breathy voice was assessed and correlated with the size of the glottic space during phonation. There was a positive (r = 0.70) correlation between glottic area and breathy voice in vocal cord palsy. There was no correlation (r = 0.002) in non-organic dysphonia. Therefore in this study population, for vocal cord palsy, glottic area is the dominant feature in determining voice quality. This relationship is not maintained in non-organic dysphonia.

    Full Text Available INTRODUCTION: Dysphonia is the main symptom of the disorders of oral communication. However, voice disorders also present with other symptoms such as difficulty in maintaining the voice (asthenia, vocal fatigue, variation in habitual vocal fundamental frequency, hoarseness, lack of vocal volume and projection, loss of vocal efficiency, and weakness when speaking. There are several proposals for the etiologic classification of dysphonia: functional, organofunctional, organic, and work-related voice disorder (WRVD.OBJECTIVE: To conduct a literature review on WRVD and on the current Brazilian labor legislation.METHODS: This was a review article with bibliographical research conducted on the PubMed and Bireme databases, using the terms "work-related voice disorder", "occupational dysphonia", "dysphonia and labor legislation", and a review of labor and social security relevant laws.CONCLUSION: WRVD is a situation that frequently is listed as a reason for work absenteeism, functional rehabilitation, or for prolonged absence from work. Currently, forensic physicians have no comparative parameters to help with the analysis of vocal disorders. In certain situations WRVD may cause, work disability. This disorder may be labor-related, or be an adjuvant factor to work-related diseases.

    Hip adductor injuries are frequent in football, and players with low adductor strength appear to be at increased risk of injury. High adductor muscle activity has been shown in the Copenhagen Adduction exercise (CA); however, an associated strength gain has not been investigated. This study aims...... to examine the eccentric hip adduction strength (EHAD) gain using the CA in-season. Two U-19 sub-elite football teams, including 24 football players, were randomized to either an 8-week supervised progressive training program in addition to the usual training (intervention) or to continue training as usual......

    Full Text Available The types of tissues accumulating glycogen and seasonal changes in glycogen content were investigated in the following shell species: pen shell Atrina lischkeana, ark shell Scapharca kagoshimensis, and Manila clam Ruditapes philippinarum. Comparison of the results showed that the adductor muscle or foot was the main glycogen reservoir and the levels varied seasonally. The adductor muscle in the pen shell showed higher glycogen content during spring and lower content during autumn. The ark shell, on the other hand, showed higher content during winter and spring and lower content during summer and autumn, while the Manila clam showed higher glycogen content during spring and summer and lower content during autumn and winter. These results revealed that the adductor muscle in pen shells and the foot in ark shells and Manila clams act as the main storage tissues for glycogen in the three species studied and that these tissues are suitable to analyze glycogen prevalence to estimate individual physiological condition.

    Cholinesterase (ChE, EC 3.1.1.7) activity was investigated in gills and adductor muscle of two bivalve species: Arca noae and Venus verrucosa. The properties of ChEs were investigated using acetylcholine iodide (ASCh), butyrylcholine iodide (BSCh) and propionylcholine iodide (PrSCh) as substrates and eserine, BW254c51 and iso-OMPA as specific inhibitors. The highest level of ChE activity in crude tissue extracts was detected with PrSCh followed by ASCh, while values obtained with BSCh were apparently low, except in A. noae adductor muscle. The enzyme activity in A. noae gills and V. verrucosa gills and adductor muscle was significantly inhibited by BW254c51, but not with iso-OMPA. ChE activity in adductor muscle of A. noae was significantly reduced by both diagnostic inhibitors. The effect of organophosphorous pesticide trichlorfon on ChE activity was investigated in vitro in both species as well as in the gills of mussels Mytilus galloprovincialis. The highest sensitivity of ChE to trichlorfon was observed in A. noae gills and adductor muscle (IC50 1.6×10(-7)M and 1.1×10(-7)M, respectively), followed by M. galloprovincialis gills (IC50 1.0×10(-6)M) and V. verrucosa gills and adductor muscle (IC50 1.7×10(-5)M and 0.9×10(-5)M, respectively). The results of this study suggest the potential of ChE activity measurement in the tissues of A. noae as effective biomarker of OP exposure in marine environment.

  6. On Risk Forecast and Risk Reduction of Tectonic Rock Bursts and Earthquakes

    Avershin, Shrepp, Kvochkin, Bojarkin and others observed that before strong rock bursts, considered as weak earthquakes, for several hours, sometimes for 2-5 days, there occurred spasmodic and sign-variable changes in deformations of rock massif adjacent areas. The works of seismologists Rikitaki, Asada, Isibasi, Matsuda, Saverensky, etc. describe a number of cases of an earthquake before which spasmodic and sign-variable deformations of earth's crust have been observed. The results of our own experimental research conducted during last decades show that abnormal spasmodic and sign-variable deformations are observed only in rocks having residual stresses. As a rule, these rocks at test after such abnormal deformations collapse dynamically, like explosions, and as a rule, such rocks represent dangerous rock bursts in deposits, located in seismically active areas (Tazhibaev K. Conditions of dynamic destruction of rocks and causes of rock bursts, Frunze 1989). It is necessary to notice that these spasmodic deformations are accompanied by formation and movement of internal discontinuities: dislocations, micro-cracks, and, hence, by redistribution of electric charges in a crystal lattice, and also in the rock as a whole. Redistribution and change in position of electric charges lead to the change of the natural electric potential and intensity of the magnetic field in the rocks massif. Before tectonic rock bursts and earthquakes together with abnormal changes of deformation, the same spasmodic and sign-variable changes of the natural electric and magnetic fields intensity occur. Based on the above-stated experimental findings, for solution of the problem of tectonic earthquakes forecast, we suggest placing the deformation measuring tool, the magnetic field intensity measuring tool and the device for measurement of natural electric potential along with seismic measurement into the seismic stations. Using abnormal, simultaneous changes of indications of all above listed

    1997-02-01

    The development of a biospecific affinity chromatographic method for the purification of octopine dehydrogenase from molluscs is described. The method utilizes immobilized NAD+ derivatives in conjunction with soluble specific substrates to promote binding. Using this method, octopine dehydrogenase has been purified to electrophoretic homogeneity in a single chromatographic step from three different marine invertebrate sources [the queen scallop, Chlamys opercularis (adductor muscle), the great scallop, Pecten maximus (adductor muscle), and the squid Loligo vulgaris (mantle muscle)]. However, the system is not applicable to the purification of octopine dehydrogenase from some other marine invertebrate sources investigated (the mussel Mytilus edulis and the topshell Monodonta lineata).

    In this study, we compared the isokinetic torques of hip flexors/extensors and abductors/adductors in soccer players suffering from osteitis pubis (OP), with normal soccer players. Twenty soccer male athletes with OP and 20 normal soccer athletes were included in this study. Peak torque/body weight (PT/BW) was recorded from hip flexor/extensor and abductor/adductor muscles during isokinetic concentric contraction modes at angular velocity of 2.1 rad · s(-1), for both groups. The results showed a significant difference between the normal and OP groups for hip flexors (P adductor and abductor muscles (P > 0.05). Regarding the hip adductor/abductor PT ratio, there was no significant difference between the normal and OP groups of athletes (P > 0.05). The OP group displayed increase in hip flexor strength that disturbed the hip flexor/extensor torque ratio of OP. Therefore, increasing the hip extensor strength should be part of rehabilitation programmes of patients with OP. PMID:24499182

  12. Evolutionary patterns of shape and functional diversification in the skull and jaw musculature of triggerfishes (Teleostei: Balistidae).

    McCord, Charlene L; Westneat, Mark W

    2016-06-01

    The robust skull and highly subdivided adductor mandibulae muscles of triggerfishes provide an excellent system within which to analyze the evolutionary processes underlying phenotypic diversification. We surveyed the anatomical diversity of balistid jaws using Procrustes-based geometric morphometric analyses and a phylomorphospace approach to quantifying morphological transformation through evolution. We hypothesized that metrics of interspecific cranial shape would reveal patterns of phylogenetic diversification that are congruent with functional and ecological transformation. Morphological landmarks outlining skull and adductor mandibulae muscle shape were collected from 27 triggerfish species. Procrustes-transformed skull shape configurations revealed significant phylogenetic and size-influenced structure. Phylomorphospace plots of cranial shape diversity reveal groupings of shape between different species of triggerfish that are mostly consistent with phylogenetic relatedness. Repeated instances of convergence upon similar cranial shape by genetically disparate taxa are likely due to the functional demands of shared specialized dietary habits. This study shows that the diversification of triggerfish skulls occurs via modifications of cranial silhouette and the positioning of subdivided jaw adductor muscles. Using the morphometric data collected here as input to a biomechanical model of triggerfish jaw function, we find that subdivided jaw adductors, in conjunction with a unique cranial skeleton, have direct biomechanical consequences that are not always congruent with phylomorphospace patterns in the triggerfish lineage. The integration of geometric morphometrics with biomechanical modeling in a phylogenetic context provides novel insight into the evolutionary patterns and ecological role of muscle subdivisions in triggerfishes.

    In professional choirs one would like to identify the incidence and severity of vocal problems due to ageing, and know how to influence them. The aim of the current study was to investigate to what extent easily obtainable voice parameters were age-related. From 47 singers of the Netherlands Radio Choir the Voice Range Profile parameters and the vibrato characteristics were measured. Dysphonia Severity Index (DSI) was calculated. We found that the age of male and female singers correlated negatively to the highest fundamental frequency and the Dysphonia Severity Index. No signs of slower and wider vibrato were found. These findings can lead to identifying adequate parameters e.g. for the ageing voice, useful in larger groups of professional singers. PMID:23116370

    2015-01-01

    Full Text Available Introduction: A microsurgical anterior cervical approach with discectomy and fusion (MACDF is one of the most widely used procedures for treating radicular disorders. This approach is highly successful; however, it is not free from complications. These can be associated with soft tissue injuries. Aim of the Study: The recognition of the risks for these complications should be identified for timely prevention and safe treatment. Materials and Methods: Study Design: Retrospective case control study. This study includes a retrospective case series of 37 patients, paying special attention to immediate complications related to the use of mechanical retraction of soft tissue (dysphagia, dysphonia, esophageal lesions and local hematoma; and a comparative analysis of the outcomes after changes in the retraction method. Results: All selected cases had a positive neurological symptom response in relation to neuropathic pain. Dysphagia and dysphonia were found during the first 72 h in 94.1% of the cases in which automatic mechanical retraction was used for more than one hour during the surgical procedure. A radical change was noted in the reduction of the symptoms after the use of only manual protective blades without automatic mechanical retraction: 5.1% dysphagia and 0% dysphonia in the immediate post-operative period, P = 0.001. Conclusions: Soft tissue damage due to the use of automatic retractors in MACDF is not minor and leads to general discomfort in the patient in spite of good neurological results. These problems most often occur when automatic retractors are used continuously for more than 1 hour, as well as when they are used in multiple levels. Dysphagia, dysphonia and local pain decreased with the use of transient manual blades for retraction, and with intermittent release following minimally invasive principles.

    Introduction. Clinical assessment of dysphonia relies on perceptual as much as instrumental methods of analysis [1]. The perceptual auditory analysis is potentially subject to several internal and external sources of bias [2]. Furthermore acoustic analyses which have been used to objectively characterize pathological voices are likely to be affected by confusion variables such as the signal processing or the hardware and software specifications [3]. For these reasons the poor correlation betw...

    Groin pain is defined as tendon enthesitis of adductor longus muscle and/or abdominal muscles that may lead to degenerative arthropathy of pubic symphises in an advanced stage. Pubic region is a point where kinematic forces cross. The balance between the adductor and abdominal muscles is of great importance, as well as the elasticity of pubic symphises which enables movement of up to 2 mm and rotation of up to 3 degrees. The weakness of the abdominal muscle wall, known as the sportsman's hernia, is the most common cause of painful groin. Groin pain is the most common in soccer players (6.24% in Croatia). Most authors believe that the main cause of groin pain is the adductor muscle overload. When active, sportsmen start to feel a dull pain in the groin region. The adductor test is of great importance for physical examination; the patient should be lying supine with his hips abducted and flexed at 80 degrees. The test is positive if the patient, while attempting to pull his/her legs against pressing in the opposite direction, feels a sharp pain in the groins. The treatment of groin pain is complex and individual, as its causes may vary from patient to patient. Gradual physical therapy combined with pharmacotherapy should be effective in most cases. The latter includes nonsteroid anti-inflammatory drugs and muscle relaxants. A physical therapy programme usually involves stretching and strengthening of adductor muscles, abdominal wall muscles, iliopsoas muscle, quadriceps, and hamstrings. In case that physical therapy and pharmacotherapy fail, surgery is needed, depending on the cause. PMID:11831125

  11. Comparative myology of the mandibular and hyoid arches of sharks of the order hexanchiformes and their bearing on its monophyly and phylogenetic relationships (Chondrichthyes: Elasmobranchii).

    2013-02-01

    The order Hexanchiformes currently comprises two families, Chlamydoselachidae (frilled sharks) and Hexanchidae (six- and seven-gill sharks), but its monophyly and relationships with other elasmobranchs are still discussed. Previous studies of hexanchiforms addressing these issues were based mainly on external morphology, teeth, skeletal features, and molecular data, whereas the employment of characters derived from variations in muscles has not been significantly explored. Dissections of four species of Hexanchiformes (including Chlamydoselachus anguineus) are reported here describing the mandibular (musculus adductor mandibulae dorsalis, m. adductor mandibulae ventralis, m. levator labii superioris, m. intermandibularis, and m. constrictor dorsalis) and hyoidean (m. constrictor hyoideus dorsalis and ventralis) arch muscles. Our results provide new data concerning the relationships of hexanchiforms to other elasmobranchs. The m. adductor mandibulae superficialis is described and illustrated in C. anguineus, contradicting previous accounts in which is was considered absent. The anteroposterior orientation of the m. adductor mandibulae superficialis in Chlamydoselachus is similar to the pattern found in hexanchids, squaloids, and hypnosqualeans (including batoids), suggesting it was secondarily lost in Echinorhinus. This muscle therefore provides further support for the inclusion of the Chlamydoselachidae and Hexanchidae in the Squalomorphi, and not basal to all other elasmobranchs or nested within an all-shark collective, as has been previously proposed. However, the m. adductor mandibulae superficialis originating at the jaw joint and with an aponeurotic insertion in hexanchids, squaliforms, and hypnosqualeans, may be a separate derived feature uniting these taxa. The insertion of the m. constrictor dorsalis is restricted to the postorbital articulation in hexanchids, whereas it extends farther anteriorly in C. anguineus. The insertion of the m. constrictor

  13. Is an Apicomplexan Parasite Responsible for the Collapse of the Iceland Scallop (Chlamys islandica Stock?

    Directory of Open Access Journals (Sweden)

    Árni Kristmundsson

    Full Text Available Due to the total and unexpected collapse of the Iceland scallop, Chlamys islandica, stocks around Iceland during the 2000s, a commercial fishing ban has been imposed on this valuable resource since 2003. Following the initial identification of an apicomplexan parasite in the scallops, a long-term surveillance program was established to evaluate the effect of the parasite on the population. The infections were highly prevalent in all shell sizes throughout the study. However, the parasite only impacts mature scallops where they cause severe macroscopic changes, characterized by an extensively diminished and abnormally coloured adductor muscle. A highly significant relationship was observed between infection intensity and gonad and adductor muscle indices. The first four years of the study, were characterized by high infection intensity and very poor condition of the adductor muscle and gonads, whilst during subsequent years, infections gradually decreased and the condition of the scallops improved. Histopathological changes were restricted to the presence of apicomplexan zoites which were widely distributed, causing varying degrees of pathology in all organs. In heavy infections, muscular and connective tissues were totally necrotized, destroying significant parts of numerous organs, especially the adductor muscle, digestive gland and gonads. The progression of the disease was in good synchrony with the mortality rates and the subsequent decline observed in the scallop stock and recruitment indices. Our findings strongly suggest that the apicomplexan parasite played a major role in the collapse of the Iceland scallop stock in Breidafjordur. In addition to causing mortality, the infections significantly impact gonad development which contributes further to the collapse of the stock in the form of lower larval recruitment. Furthermore, compelling evidence exists that this apicomplexan pathogen is causing serious disease outbreaks in other scallop

  14. Relationships between CSID and vocal fold vibratory function

    Science.gov (United States)

    Cooke, Melissa L.

    High correlations have been reported between the acoustic-based Cepstral/Spectral Index of Dysphonia (CSID) and perceptual judgments of dysphonia. This study explores whether CSID provides additional insight and explains more of the variance in HSV-based properties of vocal fold vibratory function than has been reported for other acoustic measures. Using the Analysis of Dysphonia in Speech and Voice (ADSV) program, CSID and its component variables were correlated with HSV-based measures of glottal cycle aperiodicity and glottal area for 20 subjects who underwent phonomicrosurgery. Results indicate CSID is only marginally correlated with glottal cycle aperiodicity in pre- and post-surgical conditions and does not correlate as highly as the cepstral peak prominence alone. Additionally, results reveal higher correlations when examining within-subject change from pre-surgical to post-surgical assessments rather than correlating measures across subjects. Future directions are discussed that aim at improving our understanding of the relationships between acoustic parameters and underlying phonatory function.

    Full Text Available OBJECTIVE: To evaluate the complications of anterior approach to the cervical spine in patients who underwent cervical arthrodesis with instrumentation. METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

  16. Reversal of functional disorders by aspiration, expiration and cough reflexes and their voluntary counterparts

    Full Text Available Agonal gasping provoked by asphyxia can save ~15% of mammals even from untreated ventricular fibrillation, but it fails to revive infants with sudden infant death syndrome. Our systematic study of airway reflexes in cats and other animals indicated that in addition to cough, there are 2 distinct airway reflexes that may contribute to auto-resuscitation. Gasp- and sniff-like spasmodic inspirations can be elicited by nasopharyngeal stimulation, strongly activating the brainstem generator for inspiration, which is also involved in the control of gasping. This aspiration reflex (AspR is characterized by spasmodic inspiration without subsequent active expiration and can be elicited during agonal gasping, caused by brainstem trans-sections in cats. Stimulation of the larynx can activate the generator for expiration to evoke the expiration reflex, manifesting with prompt expiration without preceding inspiration. Stimulation of the oro-pharynx and lower airways provokes the cough reflex which results from activating of both generators. The powerful potential of the AspR resembling auto-resuscitation by gasping can influence the control mechanisms of vital functions, mediating reversal of various functional disorders.The AspR in cats interrupted hypoxic apnea, laryngo- and bronchospasm, apneusis and even transient asphyxic coma, and can normalize various hypo- and hyper-functional disorders. Introduction of a nasogastric catheter evoked similar spasmodic inspirations in premature infants and interrupted hiccough attacks in adults. Coughing on demand can prevent anaphylactic shock and resuscitate the pertinent subject. Sniff representing nasal inspiratory pressure and maximal inspiratory and expiratory pressures are voluntary counterparts of airway reflexes, and are useful for diagnosis and therapy of various cardio-respiratory and neuromuscular disorders.

    Seizure is defined as "a strong shrinkage state of the skeletal muscle which is involuntary, and occurs spasmodically" and it is often accompanied by disturbance of consciousness. The typical disease which causes seizure is epilepsy. But there is many conditions causing seizure. Therefore, diagnosis of epilepsy should be careful. Seizure among eldery increases in an era of an aging population in Japan. The risk of recurrence of seizure or epilepsy in elderly is higher than that in youth. In considering of the treatment of seizure among elderly, differential diagnosis from various condition must be done. PMID:23855204

    Djenkol beans or jering (Pithecellobium jeringa) is a traditional delicacy consumed by the local population in Malaysia. Jering poisoning or djenkolism is characterized by spasmodic pain, urinary obstruction and acute renal failure. The underlying pathology is an obstructive nephropathy, which is usually responsive to aggressive hydration and diuretic therapy. We present a case of djenkolism following ingestion of jering. The patient required urgent bilateral ureteric stenting following the failure of conservative therapy. Healthcare providers need to recognize djenkolism as a cause of acute renal failure and the public educated on this potential health hazard.

    Full Text Available Background: The herbal formulation consisting of Andrographis paniculata Nees., Cassia fistula L., Foeniculum vulgare Mill. and Cuminum cyminum L. is widely used by the local traditional practitioners in rural Northern Karnataka for spasmodic abdominal pain. Objective: The present study was undertaken to evaluate safety and spasmolytic effect of poly-herbal formulation. Materials and Methods: Acute toxicity studies were carried out in Swiss mice, as per the Organization for Economic Co-operation and Development (OECD guidelines. The spasmolytic activity of the formulation was studied in isolated guinea pig ileum model using histamine and acetylcholine as agonists. The data were analyzed by one-way ANOVA, followed by Dunnetts post-hoc test and P ≤ 0.05 was considered as significant. Results: The formulation did not show any adverse toxic effects and found to be safe. It also showed significant (P < 0.05 relaxation in different agonist like histamine and acetylcholine-induced contractions in guinea pig ileum. Conclusions: Antispasmodic activity of the herbal formulation can be attributed to its atropine-like activity. The present findings, therefore, support its utility in spasmodic abdominal pain.

    AIM To study the relationship between preformation of gallstone and the kinetics and ultrastructure of sphincter of Oddi.METHODS Adult female rabbits were used and divided into 3 groups, and fed with either normal or high cholesterol diet for four or eight weeks.Each group contained eight rabbits. The manometry of sphincter of Oddi, biliary cineradiography, gallbladder volume measurement and ultrastructure observation under electron microscope were performed.RESULTS In groups Ⅰ and Ⅱ, the basal pressure in low-pressure ampulla or high pressure zone of sphincter of Oddi was elevated, the amplitude of phasic contraction was decreased and the volume of gallbladder were increased, with a significant difference (P<0.01) from those of control. Gallstones were found in group Ⅱ rabbits (7/8). Under cineradiography, low-pressure ampulla showed a spasmodic status without apparent peristaltic contraction. Under electron microscope, inside the muscular cells of sphincter of Oddi,loosening of microfilament and swelling of plasmosomes which congregated at the top were observed. The amount showed no obvious change under nitric oxide synthase (NOS) stain.CONCLUSION Twisting of the microfilament and disarrangement of kink macula densa inside the muscular cells suggested that the sphincter of Oddi was under spasmodic status. The impaired diastolic function caused and aggravated the stasis of cystic bile. The swelling plasmosome could be one of the important factors in elevating the tonic pressure of sphincter of Oddi.

    Bilateral obturator nerve injury during pelvic surgery is an infrequent cause of lower limb paraparesis. We report the case of a 45-year-old woman with a large uterine leiomyoma who underwent simple total hysterectomy and bilateral salpingectomy. At 24 h after the surgery, the patient noticed loss of muscle strength when adducting both legs. She had no problem with other movements and no sensory or sphincter abnormalities. Neurological examination confirmed that there was loss of strength only in the adductor muscles, with preserved sensory function and reflexes, suggesting bilateral obturator nerve involvement. Pelvic MRI showed a small postsurgical haematoma in the Douglas recess, but far from the obturator nerves. 2 weeks later, electromyography showed positive sharp waves and low motor unit recruitment in the adductor magnus muscles, confirming acute, bilateral obturator nerve neuropathy. The few cases of bilateral obturator neuropathy that have been reported were mostly related to abdominopelvic interventions. PMID:26689250

    A 39-year-old female with facioscapulohumeral muscular dystrophy (FSHD) was scheduled for thoracoscopic resection of an anterior mediastinal tumor. She had slowly progressive weakness and atrophy in the fascial and shoulder girdle muscles. General anesthesia was induced and maintained with propofol, remifentanil, and fentanyl combined with thoracic paravertebral block. Rocuronium-induced neuromuscular blockade was evaluated with acceleromyography at the corrugator supercilii, masseter, and adductor pollicis muscles. There was no reaction at the atrophic corrugator supercilii muscle in response to train-of-four (TOF) stimulation even before rocuronium administration. In contrast twitch responses at the masseter and adductor pollicis muscles to TOF stimulation could be evoked and the duration of action of rocuronium was found to be similar to that of the normal population. The perioperative course was uneventful. Neuromuscular monitoring sites should be carefully selected in FSHD patients because of possible inability to monitor neuromuscular function at the atrophic muscles. PMID:26790332

    The superficial veins of the lower limb can vary in their course and termination. We report a relatively rare type of variation in the course and termination of small saphenous vein. The small saphenous vein had normal origin and course in the leg. However, instead of terminating into the popliteal vein, it continued up in the posterior compartment of the thigh and terminated into the femoral vein after piercing the fleshy part of the adductor magnus muscle. This course might lead to varicosity of the small saphenous vein due to the compression by the fleshy fibres of adductor magus near its termination. The case may be of interest to general and plastic surgeons and even cardiothoracic surgeons. PMID:27134850

    Knee valgus is a potential risk factor for lower extremity (LE) injuries. Clinical movement screenings and passive range of motion (PROM) measurements may help identify neuromuscular patterns, which contribute to knee valgus. The purpose of this study was to compare LE muscle activation and PROM between subjects who display visual medial knee displacement (MKD) during a single leg squat (SLS) and those who do not. We hypothesized that muscular activation and PROM would differ between the groups. Forty physically active adults (20 controls, 20 MKDs) participated in this study. Subjects completed 10 LE PROM assessments and performed 5 SLS trials while electromyography (EMG) data were collected from 8 LE muscles. Three separate multivariate analysis of variance were used to identify group differences in EMG data, muscle coactivation, and PROM. Results during the SLS indicated hip coactivation ratios revealed smaller gluteus medius to hip adductor (GMed:Hip Add) (p = 0.028) and gluteus maximus to hip adductor (GMax:Hip Add) coactivation ratios (p = 0.007) compared with the control group. Also, the MKD group displayed significantly less passive ankle dorsiflexion with the knee extended (p = 0.047) and flexed (p = 0.034), and greater talar glide motion (p = 0.012). The findings of this study indicate that MKD during a SLS seems to be influenced by decreased coactivation of the gluteal to the hip adductor muscles and restricted dorsiflexion. Therefore, conditioning, rehabilitation, and injury prevention programs should focus on decreasing hip adductor activity, increasing hip abductor and external rotator activity, and increasing ankle dorsiflexion in hopes to decrease the incidence of these injuries.

    The "sportsman's hernia" commonly presents as a painful groin in those sports that involve kicking and twisting movements while running, particularly in rugby, football, soccer, and ice hockey players. Moreover, sportsman's hernia can be encountered even in normally physically active people. The pain experienced is recognized at the common point of origin of the rectus abdominis muscle and the adductor longus tendon on the pubic bone and the insertion of the inguinal ligament on the pubic bone. It is accepted that this chronic pain caused by abdominal wall weakness or injury occurs without a palpable hernia. We proposed the new name "pubic inguinal pain syndrome." In the period between January 2006 and November 2013 all patients afferent in our ambulatory clinic for chronic groin pain without a clinically evident hernia were assessed with medical history, physical examination, dynamic ultrasound, and pelvic and lumbar MRI. All patients were proposed for a conservative treatment and then, if it was not effective, for a surgical treatment. Our etiopathogenetic theory is based on three factors: (1) the compression of the three nerves of the inguinal region, (2) the imbalance in strength of adductor and abdominal wall muscles caused by the hypertrophy and stiffness of the insertion of rectus muscle and adductor longus muscle, and (3) the partial weakness of the posterior wall. Our surgical procedure includes the release of all three nerves of the region, the correction of the imbalance in strength with the partial tenotomy of the rectus and adductor longus muscles, and the repair of the partial weakness of the posterior wall with a lightweight mesh. This treatment reported excellent results with complete relief of symptoms after resumption of physical activity in all cases. PMID:24526429

    Background: Quadriceps muscle weakness is common in chronic obstructive pulmonary disease (COPD) but is not observed in a small hand muscle (adductor pollicis). Although this could be explained by reduced activity in the quadriceps, the observation could also be explained by anatomical location of the muscle or fibre type composition. However, the abdominal muscles are of a similar anatomical and fibre type distribution to the quadriceps, although they remain active in COPD. Cough gastric pre...

    Full Text Available Background and Aim: Spasticity is a velocity-dependent increase in tonic stretch reflexes (muscle tone with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex. The measurement of spasticity is necessary to determine the effect of treatments. The Modified Ashworth Scale is the most widely used method for assessing muscle spasticity in clinical practice and research. The purpose of this study was to investigate the interrater reliability of Modified Ashworth Scale in hemiplegic patients. Materials and Methods: Thirty subjects (16 males, 14 females with a mean age of 59.40 (SD =14.013 recruited. Shoulder adductor , elbow flexor , wrist dorsiflexor , hip adductor , knee extensor and ankle plantarflexor on the hemiplegic side were tested by two physiotherapists. Results: In the upper limb, the interrater reliability for shoulder adductor and elbow flexor muscles was fair (0.372 and 0.369, respectively. The reliability for the wrist flexors was good (0.612. The difference in Kappa value for the proximal muscle (shoulder adductor; 0.372 and the distal muscle (wrist flexor; 0.612 was significant (²X=33.87, df=1, p0.05. The mean value for the upper limb (0.505 and the lower limb (0,.516 was not significantly different (²X=0.1407, df=1, p>0.05. Conclusion: The interrater reliability of Modified Ashworth Scale was not good . The limb, upper or lower, had no significant effect on the reliability. In the upper limb, the reliability for the proximal and distal muscle was significantly different. However. The difference in the lower limb was not significant.When using the scale, one should consider it's limitation.

    2009-01-01

    Purpose The most important function of the larynx is airway protection which is provided through a polysynaptic reflex closure triggered by the receptors in the glottic and supraglottic mucosa, evoking the reflex contraction of the laryngeal muscles especially by strong adduction of vocal cords. Based on the hypotheses that central facilitation is essential for this bilateral adductor reflex and that its disturbance can result in weakened laryngeal closure, we designed this study to elucidate...

    Macintyre, Jim; Johson, Chris; Schroeder, Erik L

    2006-12-01

    Groin pain is a common and often frustrating problem in athletes who engage in sports involving kicking, rapid accelerations and decelerations, and sudden direction changes. The most common problems are adductor strain, osteitis pubis, and sports hernia. Other causes must be considered, including nerve pain, stress fractures, and intrinsic hip pathology. There is significant overlap and multiple problems frequently coexist. Accurate diagnosis leads to directed treatment, with rehabilitation focused on functional closed-chain strengthening and core stability. PMID:17067496

    The shoulder impingement syndrome may occur through the imbalance of the muscle strength around the shoulder of baseball players. Our previous study suggested that latissimus dorsi (LD), the back muscle which is the adductor and internal rotator of the shoulder, would possibly prevent shoulder impingement. The purposes of this study were to clarify the correlation between the muscle strength around shoulder and impingement signs in baseball players and to identify the influence of LD on impin...

    The selection of a DNA extraction method is a critical step when subsequent analysis depends on the DNA quality and quantity. Unlike mammals, for which several capable DNA extraction methods have been developed, for molluscs the availability of optimized genomic DNA extraction protocols is clearly insufficient. Several aspects such as animal physiology, the type (e.g., adductor muscle or gills) or quantity of tissue, can explain the lack of efficiency (quality and yield) in molluscs genomic D...

    Long non-coding RNAs (LncRNAs) are abundant in the genome of higher forms of eukaryotes and implicated in regulating the diversity of biological processes partly because they host microRNAs (miRNAs), which are repressors of target gene expression. In vertebrates, miR-133 regulates the differentiation and proliferation of cardiac and skeletal muscles. Pinctada martensii miR-133 (pm-miR-133) was identified in our previous research through Solexa deep sequencing. In the present study, the precise sequence of mature pm-miR-133 was validated through miR-RACE. Stem loop qRT-PCR analysis demonstrated that mature pm-miR-133 was constitutively expressed in the adductor muscle, gonad, hepatopancreas, mantle, foot, and gill of P. martensii. Among these tissues, the adductor muscle exhibited the highest pm-miR-133 expression. Target analysis indicated that pm-RhoA was the potential regulatory target of pm-miR-133. Bioinformatics analyses revealed that a potential LncRNA (designated as Lnc133) with a mature pm-miR-133 could generate a hairpin structure that was highly homologous to that of Lottia gigantea. Lnc133 was also highly expressed in the adductor muscle, gill, hepatopancreas, and gonad. Phylogenetic analysis further showed that the miR-133s derived from chordate and achordate were separated into two classes. Therefore, Lnc133 hosting pm-miR-133 could be involved in regulating the cell proliferation of adductor muscles by targeting pm-RhoA.

    1999-05-01

    Obturator neuropathy is a cause of exercise-related groin pain, particularly in those who play sports that involve much running, twisting and turning, and kicking. Symptoms include pain that begins insidiously at the adductor origin on the pubic bone and worsens with exercise. Diagnostic measures include reproduction of pain by stretching the pectineus muscle after exercise, electromyography, and a local anesthetic block of the obturator nerve. Surgery allows most patients to resume previous levels of activity.

    We evaluated the leg and thigh muscles of 4 control subjects and 10 patients with myotonic dystrophy using computed tomography. Taking previous reports about the skeletal muscle CT of myotonic dystrophy into account, we concluded that the following 5 features are characteristic of myotonic dystrophy: 1. The main change is the appearance of low-density areas in muscles; these areas reflect fat tissue. In addition, the muscle mass decreases in size. 2. The leg is more severely affected than the thigh. 3. In the thigh, although the m. quadriceps femoris, especially the vastus muscles, tends to be affected, the m. adductor longus and magnus tend to be preserved. 4. In the leg, although the m. tibialis anterior and m. triceps surae tend to be affected, the m. peroneus longus, brevis, and m. tibialis posterior tend to be preserved. 5. Compensatory hypertrophy is often observed in the m. rectus femoris, m. adductor longus, m. adductor magnus, m. peroneus longus, and m. peroneus brevis, accompanied by the involvement of their agonist muscles.

    During extended periods of skeletal unloading, losses in strength and density of the proximal femur will occur. In long-duration spaceflight, resistive exercise is used to replace the normal loads exerted on the spine and hip. At the present time, there is no conclusive evidence that hip bone loss has been prevented in this scenario. Our group has recently developed and clinically evaluated a multifunctional exercise system, the Combined Countermeasure Device (CCD). The CCD comprises a low-footprint Stuart Platform for lower-body resistance exercise and balance training, and a cardiovascular exercise bicycle. A consideration for resistance exercise was targeting of the hip abductor and adductor muscles, which attach directly at the hip and which should subject it to the largest loads. In our training study, we found that CCD exercise increased hip adductor and abductor strength, and modeling results suggest that this exercise exerts forces on the hip of approx. 4-6 body weights at 1g, compared to forces of approx.2.5 body weight y squatting exercise. In our current study, we hypothesize that abductor and adductor exercise will increase the density and strength of the proximal femur.

    We describe a new technique of single interfascial injection for 25 patients scheduled for transurethral bladder tumor resection. An ultrasound probe was placed at the midline of inguinal crease and moved medially and caudally to visualize the fascial space between the adductor longus (or pectineus) and adductor brevis muscles. We injected 20 mL 1% lidocaine containing epinephrine into the interfascial space using a transverse plane approach to make an interfascial injection, not an intramuscular swelling pattern. And just distally, firm pressure was applied for 3 min. Afterwards, surgery was performed under spinal anesthesia. The time required for identification and location of the nerve was 20 ± 15 and 30 ± 15 s, respectively. Adductor muscle strength, which was measured with a sphygmomanometer, decreased in all patients, from 122 ± 26 mmHg before blockade to 63 ± 11 mmHg 5 min after blockade. No movement or palpable muscle twitching occurred in 23 cases, slight movement of the thigh not interfering with the surgical procedure was observed in 1 case, thus the obturator reflex was successfully inhibited in 96% of cases. Ultrasound-guided single interfascial injection is an easy and successful technique for obturator nerve block. PMID:21918855

    Aim: To investigate whether the prophylactic local delivery of mobilized periph-eral blood mononuclear cells (M-PBMNC) could prevent peripheral microangio-pathy in diabetic nude mice. Methods: Diabetic nude mice were induced with intraperitoneal injections of streptozotocin. With the time course of diabetes, we detected the capillary and arteriole density of mice adductor muscles by immuno-histopathy. In situ apoptosis was detected by using TdT-mediated dUTP nick end labeling (TUNEL) methods. M-PBMNC were labeled and locally delivered to the adductor muscles. Mononuclear cells were also isolated and cultured in vitro for the detection and counting of endothelial progenitor cells(EPC). Results: Rarefication of capillaries and arterioles, enhanced apoptosis in adductor muscles,and reduced circulating EPC in diabetic nude mice. Prophylactic local delivery of M-PBMNC halted the progression of microvascular rarefaction in hind-limb skel-etal muscles by inhibiting apoptosis. We detected the survival, migration and incorporation of transplanted M-PBMNC into the murine vasculature in vivo. In addition, more EPC were available from M-PBMNC than non-mobilized cells.Conclusion: These results suggested that the prophylactic local delivery of M-PBMNC may represent a novel approach for the treatment of microvascular complications in diabetics.

    Full Text Available Background: During transurethral resection surgery (TUR, accidental stimulation of the obturator nerve can cause violent adductor contraction, leading to serious intraoperative complications. General anesthesia with muscle relaxation is currently the preferred technique for TUR surgery. Spinal anesthesia combined with obturator nerve block has also been used for TUR surgery in geriatric population. Blind, anatomical methods for identifying the obturator nerve are often unsatisfactory. Therefore, we conducted this prospective study to validate the efficacy of ultrasound-guided obturator nerve block (USONB during TUR procedures. Methods: Eighteen male patients undergoing TURP surgery under spinal anesthesia were included in the study. Bilateral USONB with maximum 20 ml of 1% lidocaine per patient was performed. An independent observer was present to monitor any adduction movements during the operation and to record patient and surgeon satisfactions. Results: In all patients, obturator nerve was visualized from the first attempt, requiring an average of 4.3 min for blocking of each side. USONB was successful (97.2% in preventing an adductor spasm in all except one patient. Patient′s and surgeon′s satisfaction were appropriate. In all patients, adductor muscle strength recovered fully within 2 h following the surgical procedure. Conclusions: USONB is safe and effective during TUR surgery. It provides optimal intra-and postoperative conditions.

  11. Distribution of skeletal muscle involvement in autosomal recessive distal muscular dystrophy

    International Nuclear Information System (INIS)

    Distribution of skeletal muscle involvement in 5 cases with autosomal recessive distal muscular dystrophy was studied clinically and by computed tomography (CT). Manual muscle test showed muscle involvement with a predilection for flexors in the lower leg and adductors in the thigh. Flexion and extension of the thigh and the lower leg was impaired to similar degree. In progressed cases, neck flexors and trunk muscles were also affected mildly. CT disclosed more clearly the preferential involvement of flexors in the lower leg, and involvement of both hamstrings · adductors group and extensors group of the thigh to similar degree. However, m. popliteus was curiously well preserved. In addition, there was a stage showing high density and hypertrophy of m. sartorius, m. gracilis, m. adductor, m. biceps femoris, m. semimenbranosus, m. semitendinosus or m. rectus femoris, which in thought to be compensatory hypertrophy. M. gluteus minimus in the pelvic girdle and m. dorsi proprii in the trunk were also liable to be affected. The CT findings are regarded as characteristic features noted clearly before muscle weakness and atrophy become apparent clinically. CT is very useful for distinguishing distal muscular dystrophy from rimmed vacuolar distal myopathy in which m. quadriceps femoris and flexors of the lower leg are usually well preserved without compensatory hypertrophy on CT.

    We examined the soft tissues of live freshwater mussels, Eastern elliptio Elliptio complanata, via magnetic resonance imaging (MRI), acquiring data with a widely available human whole-body MRI system. Anatomical features depicted in the profile images included the foot, stomach, intestine, anterior and posterior adductor muscles, and pericardial cavity. Noteworthy observations on soft tissue morphology included a concentration of lipids at the most posterior aspect of the foot, the presence of hemolymph-filled fissures in the posterior adductor muscle, the presence of a relatively large hemolymph-filled sinus adjacent to the posterior adductor muscle (at the ventral-anterior aspect), and segmentation of the intestine (a diagnostic description not reported previously in Unionidae). Relatively little is known about the basic biology and ecological physiology of freshwater mussels. Traditional approaches for studying anatomy and tissue processes, and for measuring sub-lethal physiological stress, are destructive or invasive. Our study, the first to evaluate freshwater mussel soft tissues by MRI, clarifies the body plan of unionid mussels and demonstrates the efficacy of this technology for in vivo evaluation of the structure, function, and integrity of mussel soft tissues. ?? 2008, The American Microscopical Society, Inc.

  14. Variations in the pallial organ sizes of the invasive oyster, Crassostrea gigas, along an extreme turbidity gradient

    2009-11-01

    Spatial size variations of labial palps, gills and the adductor muscle of the invasive feral oyster, Crassostrea gigas, were studied along two gradients of suspended particulate matter (SPM) concentrations in the temperate macrotidal Bourgneuf Bay, (annual mean SPM concentration gradient of 21.0-154.0 mg l -1) and the adjacent Loire Estuary (annual mean SPM concentration gradient of 24.1-630.4 mg l -1) on the French Atlantic Coast. The gill-to-palp (G:P) ratios decreased with increasing turbidity, both in the bay and the estuary. Changes in G:P ratios were chiefly related to palp area variations, increasing gradually from low turbidity to very high-turbidity sites, while gill area showed no clear relationship with turbidity conditions. The G:P ratio, showing a significant relationship ( r2 = 0.97) with SPM concentrations, is proposed as a pallial organ index of oyster acclimation to turbidity conditions. The area of the striated part of the adductor muscle was always greater than that of the smooth one, and adductor muscle area tended to decrease when SPM concentration increased. These observations show the morphological capacity of the oyster C. gigas to tolerate SPM concentrations above the feeding cessation thresholds previously determined experimentally. They also suggest that pallial organ size variations could help explain the success of recent feral oyster invasions in temperate turbid ecosystems.

  15. Influences of laryngeal afferent inputs on intralaryngeal muscle activity during vocalization in the cat.

    1997-01-01

    The present study was undertaken to elucidate the possible role of the laryngeal afferent inputs in the regulation of intralaryngeal muscle activity during vocalization. We studied the influences of airflow and/or pressure applied to the larynx on intralaryngeal muscle activity during vocalization in ketamine-anesthetized cats. Vocalization was induced by airflow applied to the upper airway, which was isolated from the lower airway, during pontine call site stimulation. When the upper airway was open to the atmosphere through the nostrils and mouth, the airflow increased not only the vocal fold adductor and tensor activities but also the duration of these activities. The adductor and tensor activities were increased suddenly at a critical subglottic pressure level equivalent to the subglottic pressure threshold for vocalization. These effects were significantly reduced by sectioning of the internal branch of the superior laryngeal nerve or by lidocaine application to the laryngeal mucosa. Sustained pressure applied to the isolated upper airway, when the mouth and nostrils were occluded, did not affect adductor or tensor activities. These results indicate that the afferent inputs evoked by vocal fold stretching or vibration play an important role in the motor control of intralaryngeal and respiratory muscles during vocalization.

    Introduction Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. Objective To identify factors associated with clinical and topographical features of LTB. Method a retrospective cross-sectional study was conducted from the medical records of 36 patients with confirmed LTB diagnosis. Results Dysphonia and cough were the main symptoms presented by patients and the true vocal folds the most frequently affected site. The average of the duration of the disease evolution was significantly higher in patients with dysphonia than in patients without this symptom. We observed association between dysphonia and true vocal fold lesions and between odynophagia and lesions in the epiglottis, arytenoids and aryepiglottic folds. Odynophagia was more frequent in individuals with lesions in four or more laryngeal sites. Weight loss equal or above 10% of the body weight was more frequent in patients with odynophagia as first symptom and in patients with ulcerated lesion. Dyspnea on exertion was more frequent in individuals with more extensive laryngeal lesions. The percentage of smokers with lesions in four or more laryngeal sites was greater than that found in non-smokers. Laryngeal tissue fragment bacilloscopy and culture examinations were less positive than sputum ones. Conclusions Smoking appears to be associated with the development of more extensive LTB lesions, and LTB with dyspnea on exertion and odynophagia with consequent impairment of nutritional status. We emphasize the need for histopathologic confirmation, once positive sputum bacteriological examinations seem not to necessarily reflect laryngeal involvement. PMID:27077734

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

    Full Text Available Hoarseness and dysphonia are often a result of vocal cord polyps which in turn, are linked to vocal trauma. We report the case of vocal polyps in the setting of a 27-year old male with a history only remarkable for Tourette syndrome. We review the literature regarding etiology and pathophysiology of vocal cord lesions and propose vocal tics in Tourette syndrome as an under-recognized etiology. In this way, we also review therapies that may aid in treating not only the vocal cord lesions but also particularly in the setting of vocal tics.

    2013-01-01

    Full Text Available A 79-year-old man, with history of recent laparoscopic cholecystectomy, came to our attention for persistent hiccup, dysphonia, and dysphagia. Noninvasive imaging studies showed a nodular lesion in the right hepatic lobe with transdiaphragmatic infiltration and increased tracer uptake on positron emission tomography. Suspecting a malignant lesion and given the difficulty of performing a percutaneous transthoracic biopsy, the patient underwent surgery. Histological analysis of surgical specimen showed biliary gallstones surrounded by exudative inflammation, resulting from gallbladder rupture and gallstones spillage as a complication of the previous surgical intervention.

    Full Text Available Foreign body aspiration is unusual in adults, except those who are debilitated or have neuropsychiatric disorders. It can be a life-threatening situation and it often requires a high index of suspicion, because the diagnosis can be obscure. Prompt diagnosis and intervention through foreign body retrieval are critical to prevent significant morbidity and mortality. We present a case of denture aspiration by a debilitated 90 years old man. He had aspirated his complete upper denture to pharynx causing incomplete obstruction with pleasure whistling respiratory sound, dyspnea, dysphagia and dysphonia. He underwent successful retrieval of the dental plate manually by fingers with complete resolution of symptoms.

    Epidermolysis bullosa acquisita is a rare entity belonging to the auto-immune cutaneous blistering disorders of the dermo-epidermal junction. Clinical manifestations are generally cutaneous including the development of sub-epidermal blisters. Mucosal manifestations should be systematically looking for, but laryngeal involvement remains uncommon. We report an 81-year-old woman who presented with dysphagia, dyspnea and dysphonia as the presenting features of laryngeal involvement of an epidermolysis bullosa acquisita. This is the tenth reported case in the literature. We describe our diagnostic approach and the therapeutic management, comparing them with the literature.

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

    Penetrating atherosclerotic aortic ulcer is a rare entity with poor prognosis in the setting of acute aortic syndrome. In the literature, cases like the present one, located in the aortic arch, starting with chest pain and evolving with dysphonia, are even rarer. The present report emphasizes the role played by computed tomography in the diagnosis of penetrating atherosclerotic ulcer as well as in the differentiation of this condition from other acute aortic syndromes. Additionally, the authors describe a new therapeutic approach represented by a hybrid endovascular surgical procedure for treatment of the disease. (author)

    The doctoral thesis is based on eight papers published in peer-reviewed journals and a review of the literature. The papers are published between 1997 and 2013 in cooperation with Sankt Elisabeth Hospital, Herlev Hospital, Glostrup Hospital, Rigshospitalet, Hvidovre Hospital, Amager Hospital, Copenhagen Trial Unit, and Institute of Preventive Medicine, Copenhagen. Groin injuries in sport are very common and in football they are among the most common and most time-consuming injuries. These injuries are treated very differently around the world. There is no consensus in the literature regarding definitions, examination methods, diagnosis or treatment and in general the level of evidence is very low. There is a need for identification of the painful anatomical structures, how to examine them and how to define clinical entities to develop effective treatment and prevention. The aim of these studies were: - To review the literature to create an overview of the ideas and the knowledge in order to plan future studies in this field. - Develop and test clinical examination techniques of the relevant tendons and muscles in the region. - Since no evidence-based diagnosis exist; to develop a set of clinical entities to identify the different groups of patients. - To test the effect of a dedicated exercise program developed for treatment of long-standing adductor-related groin pain in athletes in a randomised clinical trial comparing it to the treatment modalities used at that time. - To examine the long-term effect of the above mentioned training program for treatment of long-standing adductor-related groin pain. - To develop a training program for prevention of groin injuries in soccer and test it in a randomised clinical trial. - To describe the occurrence and presentation in clinical entities of groin injuries in male football and to examine the characteristics of these injuries. - Evaluate if radiological signs of femuro-acetabular impingement (FAI) or dysplasia affect the

    Full Text Available Parkinson’s disease (PD is a progressive and chronic nervous system disease that impairs the ability of speech, gait, and complex muscle-and-nerve actions. Early diagnosis of PD is quite important for alleviating the symptoms. Cost effective and convenient telemedicine technology helps to distinguish the patients with PD from healthy people using variations of dysphonia, gait or motor skills. In this study, a novel telemedicine technology was developed to detect PD remotely using dysphonia features. Feature transformation and several machine learning (ML methods with 2-, 5- and 10-fold cross-validations were implemented on the vocal features. It was observed that the combination of principal component analysis (PCA as a feature transformation (FT and k-nearest neighbor (k-NN as a classifier with 10-fold cross-validation has the best accuracy as 99.1%. All ML processes were applied to the prerecorded PD dataset using a newly created program named ParkDet 2.0. Additionally, the blind test interface was created on the ParkDet so that users could detect new patients with PD in future. Clinicians or medical technicians, without any knowledge of ML, will be able to use the blind test interface to detect PD at a clinic or remote location utilizing internet as a telemedicine application.

    Full Text Available Vocal folds play a crucial role in voice production. The physiological vibrations of vocal folds depend on the unchanged multilayered structure of the vocal folds mucosa. Morphological changes of mucosa are the cause of voice quality disorders — dysphonia. The aim of this study was to determine the morphological base of dysphonia in patients with vocal folds atrophy. A group of 24 patients with larynx atrophy confirmed by endoscopic (VLS and stroboscopic (VLSS examination of the larynx was included in the study. The morphological assessment of the larynx mucosa was carried out with the use of the transmission electron microscopy (TEM. Ultramorphological examinations revealed changes in the epithelium, basal membrane and lamina propria of the vocal folds mucosa. An increased number of collagenous fibers, fibroblasts with signs of vacuolar degeneration inflammatory cells and a decreased number of blood vessels and pericytes were observed. Morphological changes found in the epithelium, basal membrane and lamina propria of the vocal folds mucosa were the cause of disorders of vocal folds vibrations registered in the stroboscopic examination of the larynx (VLSS.

    Full Text Available Automatic detection of voice pathologies enables non-invasive, low cost and objective assessments of the presence of disorders, as well as accelerating and improving the process of diagnosis and clinical treatment given to patients. In this work, a vector made up of 28 acoustic parameters is evaluated using principal component analysis (PCA, kernel principal component analysis (kPCA and an auto-associative neural network (NLPCA in four kinds of pathology detection (hyperfunctional dysphonia, functional dysphonia, laryngitis, vocal cord paralysis using the a, i and u vowels, spoken at a high, low and normal pitch. The results indicate that the kPCA and NLPCA methods can be considered a step towards pathology detection of the vocal folds. The results show that such an approach provides acceptable results for this purpose, with the best efficiency levels of around 100%. The study brings the most commonly used approaches to speech signal processing together and leads to a comparison of the machine learning methods determining the health status of the patient
