    Full Text Available Objective:The study aimed at differentiating Adductor Spasmodic Dysphonia (ADSD from Muscle Tension Dysphonia (MTD using acoustic measurements . Method: Perceptual as well as acoustic analysis of the voice was done on 12 patients of Adductor Spasmodic dysphonics and Muscle tension dysphonics each. The age of these patients ranged between 30 to 64 years . Results: Adductor spasmodic dysphonics statistically differed from muscle tension dysphonia in the acoustic parameters of voice break, harmonic to noise ratio, and jitter. The parameters which showed maximum significance of differences were voice break which was presented only by the adductor spasmodic dysphonics and harmonic to noise ratio which was affected in muscle tension dysphonia. Conclusion: Voice breaks were found to be more sensitive in discriminating adductor spasmodic dysphonia from muscle tension dysphonia in the present study. Percentage of voice break correlated with perceptual assessment of severity.

    Type II thyroplasty, or laryngeal framework surgery, is based on the hypothesis that the effect of adductor spasmodic dysphonia (AdSD) on the voice is due to excessively tight closure of the glottis, hampering phonation. Most of the previous, partially effective treatments have aimed to relieve this tight closure, including recurrent laryngeal nerve section or avulsion, extirpation of the adductor muscle, and botulinum toxin injection, which is currently the most popular. The aim of this study was to assess the effects of type II thyroplasty on aerodynamic and acoustic findings in patients with AdSD. Case series. University hospital. Ten patients with AdSD underwent type II thyroplasty between August 2006 and December 2008. Aerodynamic and acoustic analyses were performed prior to and six months after surgery. Mean flow rates (MFRs) and voice efficiency were evaluated with a phonation analyzer. Jitter, shimmer, the harmonics-to-noise ratio (HNR), standard deviation of the fundamental frequency (SDF0), and degree of voice breaks (DVB) were measured from each subject's longest sustained phonation sample of the vowel /a/. Voice efficiency improved significantly after surgery. No significant difference was found in the MFRs between before and after surgery. Jitter, shimmer, HNR, SDF0, and DVB improved significantly after surgery. Treatment of AdSD with type II thyroplasty significantly improved aerodynamic and acoustic findings. The results of this study suggest that type II thyroplasty provides relief from voice strangulation in patients with AdSD.

    Adductor spasmodic dysphonia (AdSD) is a controversial and enigmatic voice disorder. It is generally accepted that it has a neurologic, although undetermined, cause, and it is accompanied by much psychological and physical distress. In this prospective study, standardized psychometric tests were use

    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.

    Spasmodic dysphonia voices form, in the same way as substitution voices, a particular category of dysphonia that seems not suited for a standardized basic multidimensional assessment protocol, like the one proposed by the European Laryngological Society. Thirty-three exhaustive analyses were performed on voices of 19 patients diagnosed with adductor spasmodic dysphonia (SD), before and after treatment with Botulinum toxin. The speech material consisted of 40 short sentences phonetically selected for constant voicing. Seven perceptual parameters (traditional and dedicated) were blindly rated by a panel of experienced clinicians. Nine acoustic measures (mainly based on voicing evidence and periodicity) were achieved by a special analysis program suited for strongly irregular signals and validated with synthesized deviant voices. Patients also filled in a VHI-questionnaire. Significant improvement is shown by all three approaches. The traditional GRB perceptual parameters appear to be adequate for these patients. Conversely, the special acoustic analysis program is successful in objectivating the improved regularity of vocal fold vibration: the basic jitter remains the most valuable parameter, when reliably quantified. The VHI is well suited for the voice-related quality of life. Nevertheless, when considering pre-therapy and post-therapy changes, the current study illustrates a complete lack of correlation between the perceptual, acoustic, and self-assessment dimensions. Assessment of SD-voices needs to be tridimensional.

    To understand the vowel duration and statement reading of the adductor spasmodic dysphonia (ADSD) patients compared with their normal controls, and provide ideas for clinical diagnosis and treatment. Twenty-nine ADSD patients were included in the research, with 31 normal controls. All subjects filled in form voice handicap index (VHI) by themselves. Maximum phonetic time (MPT) and maximum loudness phonetic time(MLPT) were tested on /a/ sound for all patients. Also, all the patients were required to read aloud a standard mandarin assay named , duration were measured with Praat5. 0 software after sounds were collected. A one-way t-test was performed to compare spasmodic group with control group on VHI, MPT, MLPT and duration for reading standard sentences. Pearson/Spearman correlation was tested. Result: The VHI of the 29 ADSD patients is 89±12, and their normal controls 15±16, indicating that the VHI in ADSD group is significantly higher than in the control group(Preading of the ADSD group is (55.0±14. 2)s, and the control group is (37. 8±4. 8)s, indicating that the duration of standard sentence reading in the ADSD group is significantly longer than the control group (Pvowels are not lasting compared with normal people. In the meantime, their ability to read sentences is worse than normal people, needing longer time to complete the reading task. There is a significant correlation between MLPT and MPT, which can be used as an alternative to MPT.

    Spasmodic dysphonia (SD) remains one of the most difficult of laryngeal pathologies to treat. With limited role for speech therapy, various surgical modalities have been tried with various success rates. The objective of the study is to report the results of vocal outcome after thyroarytenoid myoneurectomy in patients of adductor spasmodic dysphonia (ASD). 15 patients of ASD were selected. GRBAS, and voice handicap index (VHI) were used for perceptual evaluation of voice. Thyroarytenoid myoneurectomy was performed by vaporizing the muscular layer of the vocal fold with CO2 laser, at an intensity of 6 W with 1.2 mm diameter in scanner mode. Voice analysis was repeated at 12, 24 and 48 months follow-up. Preoperative GRBAS scores and VHI score of all the patients were poor. At 12 months 12/15 (80 %) patients having strain score of 0. There was marked improvement in VHI scores at 6 months. 10/15 (67 %) patients have been followed up for 24 months. 5/10 (50 %) patients have strain (S) value of 0. VHI scoring of 5/10 (50 %) patients was <30. Two of the four patients completed 48 months follow-up had a strain (S) value of 0, one patient has strain value of 1 and one patient had strain value of 2. 2/4 patients had VHI score of <30; one patient had that of 40. Trans-oral CO2 laser thyroarytenoid myoneurectomy shows significant long-term improvement in voice quality in terms of reduced speech brakes, effort and strain in voice.

    In this prospective study, the efficacy of botulinum toxin (Botox) injections in patients with adductor spasmodic dysphonia (AdSD) was assessed by 3 different modalities: perceptual and acoustic analyses and subjective self-assessment. This was done by comparing AdSD patients' pretreatment and posttreatment values and comparing these values with those of normal control speakers. In contrast to most other studies, the posttreatment status was defined as the optimal voice quality as judged by the patient. The aim of the study was to assess to what extent Botox injections actually improve voice quality and function. The AdSD subjects rated a significantly improved voice quality and function after Botox treatment. However, the results were never within normal limits. Perceptually, the characteristic and severely impaired AdSD voice improved, but another "type" of pathological voice was detected after Botox treatment. Acoustic analyses demonstrated a significant improvement, as well. Nevertheless, the "optimally" treated AdSD voice still remained significantly deviant as compared to normal voice production. Currently, Botox injection is the therapy of first choice for AdSD. Although significant improvement could be measured in our study perceptually, acoustically, and subjectively, the optimal voice that was achieved never fully matched normal voice quality or function.

    The purpose of this study was to examine the effect of severity of adductor spasmodic dysphonia (ADSD) and information about it on unfamiliar listeners' attitudes about speakers' personal characteristics, perceived vocal effort, and listener comfort on the basis of ratings of speech recordings. Fifteen women with ADSD and 5 controls provided speech samples. Forty-five unfamiliar listeners were randomized into 3 groups. Listeners in Group 1 received no information, listeners in Group 2 were told that some speakers had voice disorders or had no voice concerns, and listeners in Group 3 were provided diagnostic labels for each speaker and information about ADSD. Listeners then rated speech samples for attitudes, perceived vocal effort, and listener comfort. Speakers with ADSD were judged significantly worse than controls for attitudes related to "social desirability" and "intellect." There was no effect of severity on "personality" attributes. However, provision of a diagnostic label resulted in significantly more favorable personality ratings than when no label was provided. Perceived vocal effort and comfort became significantly more negative as ADSD severity increased. Finally, most listener ratings were unaffected by provision of additional information about ADSD. Listeners' perceptions about speakers with ADSD are difficult to change. Directions for counseling and public education need future study.

    Individuals with adductor spasmodic dysphonia (ADSD) have reported that unfamiliar communication partners appear to judge them as sneaky, nervous or not intelligent, apparently based on the quality of their speech; however, there is minimal research into the actual everyday perspective of listening to ADSD speech. The purpose of this study was to investigate the impressions of listeners hearing ADSD speech for the first time using a mixed-methods design. Everyday listeners were interviewed following sessions in which they made ratings of ADSD speech. A semi-structured interview approach was used and data were analyzed using thematic content analysis. Three major themes emerged: (1) everyday listeners make judgments about speakers with ADSD; (2) ADSD speech does not sound normal to everyday listeners; and (3) rating overall severity is difficult for everyday listeners. Participants described ADSD speech similarly to existing literature; however, some listeners inaccurately extrapolated speaker attributes based solely on speech samples. Listeners may draw erroneous conclusions about individuals with ADSD and these biases may affect the communicative success of these individuals. Results have implications for counseling individuals with ADSD, as well as the need for education and awareness about ADSD.

    Type II thyroplasty (TPII) is one of the surgical options offered in the management of adductor spasmodic dysphonia (AdSD); however, there have been no detailed reports of its safety and associated complications during the perioperative period. Our aim was to assess the complications and safety of TPII. TPII was performed for consecutive 15 patients with AdSD from April 2012 through May 2014. We examined retrospectively the perioperative complications, the degree of surgical invasion, and recovery process from surgery. All patients underwent successful surgery under only local anesthesia. Vocal fold erythema was observed in 14 patients and vocal fold edema in 10 patients; however, all of them showed complete resolution within 1 month. No patient experienced severe complications such as acute airway distress or hemorrhage. Fourteen patients were able to have oral from the 1st postoperative morning, with the remaining patient able to have oral intake from the 2nd postoperative day. In addition, no patient experienced aspiration postoperatively. In conclusion, only minor complications were observed in association with TPII in this study. No dysphagia was observed postoperatively, which is an advantage over other treatments. The results of our study suggest that TPII is a safe surgical treatment for AdSD.

    The purpose of this study was to compare cortical inhibition in the hand region of the primary motor cortex between subjects with focal hand dystonia (FHD), adductor spasmodic dysphonia (AdSD), and healthy controls. Data from 28 subjects were analyzed (FHD n=11, 53.25 ± 8.74 y; AdSD: n=8, 56.38 ± 7.5 y; and healthy controls: n=941.67 ± 10.85 y). All subjects received single pulse TMS to the left motor cortex to measure cortical silent period (CSP) in the right first dorsal interosseus (FDI) muscle. Duration of the CSP was measured and compared across groups. A one-way ANCOVA with age as a covariate revealed a significant group effect (p<0.001). Post hoc analysis revealed significantly longer CSP duration in the healthy group vs. AdSD group (p<0.001) and FHD group (p<0.001). These results suggest impaired intracortical inhibition is a neurophysiologic characteristic of FHD and AdSD. In addition, the shortened CSP in AdSD provides evidence to support a widespread decrease in cortical inhibition in areas of the motor cortex that represent an asymptomatic region of the body. These findings may inform future investigations of differential diagnosis as well as alternative treatments for focal dystonias.

    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.

    G. Paul Moore influenced the study of spasmodic dysphonia (SD) with his 1960 publication that examined the neurological, medical, and vocal fold behavior in a group of patients with adductor spasmodic dysphonia (ADSD). This review of advances in the diagnosis and treatment of SD follows a time line of research that can be traced in part to the early work of Moore et al. This article reviews the research in ADSD over the past 50 plus years. The capstone events that brought SD to its present day level of management by laryngologists and speech-language pathologists are highlighted. A look to the future to understand more of the disorder is offered for this debilitating disorder.

    Spasmodic dysphonia (SD) is rather a rare voice disorder. It is most often seen in woman aged 40-50. The disease is caused by deep emotional and neurological disorders of extrapyramidal system. Two main clinical forms of SD are distinguished: about 90% of cases - adductor spasmodic dysphonia and abductor spasmodic dysphonia roughly 10%. Conservative therapy does not always yield sufficient effects. Botulinum toxin - type A injections into the thyroarytenoid muscle are also used in therapy. Though results are temporary and reversible. Among phonosurgical methods thyroplasty type II according to Isshiki and tyroarytenoid muscle myectomy (TAM) should be also mentioned among phonosurgical methods. The aim of the work is to evaluate results of conservative and phonosurgical treatment of SD. Spasmodic dysphonia markedly restricts communication process of patients and public relations both social and occupational.

    Botulinum toxin has been widely accepted as an effective therapy for controlling the symptoms of adductor spasmodic dysphonia (ADSD). Reported experience with botulinum treatment for abductor spasmodic dysphonia (ABSD) has been less impressive. Factors that may impair outcomes for ABSD include differences in the pathophysiology of ADSD and ABSD and limitation of maximal dose from airway restriction with posterior cricoarytenoid muscle (PCA) weakness. We report our experience with botulinum injection of the PCA with an asymmetric dose escalation protocol, based on clinical observations that in ABSD, abductor spasms are often stronger on one side, usually the left. The nondominant side was injected with 1.25 units. Dominant side dose began at 5 units, with step-wise increments of 5 units per week until one of three endpoints was reached: Elimination of breathy voice breaks, complete abductor paralysis of the dominant side, or airway compromise. Fourteen of 17 patients achieved good or fair voice, with dominant-side doses ranging from 10 to 25 units. Exercise intolerance limited PCA dose in two patients. One patient had persisting breathiness that improved with medialization thyroplasty. Asymmetric botulinum toxin injection into PCA muscles can suppress abductor spasm in patients with ABSD, but breathiness may persist, because of inadequate glottal closure.

    Parry-Romberg syndrome is a rare clinical entity characterised by progressive hemifacial atrophy with appearance of 'saber'. Various neurological and otorhinolaryngological disorders are associated with this syndrome. The association of Parry -Romberg syndrome with Spasmodic dysphonia has rarely been reported. A 37 year old female presented with progressive atrophy of tissues of left side of face for 10 years and change in voice for 1 year. On examination, wasting and atrophy of tissues including tongue was noted on left side of the face. ENT examination revealed adductor spasmodic dysphonia. We report the rare association of Parry -Romberg syndrome with spasmodic dysphonia.

    Spasmodic dysphonia, a form of the neurologic condition known as dystonia, results from involuntary spasms of the larynx, producing interruptions of speech and changes in voice quality. The pathogenesis of spasmodic dysphonia is not well understood. However, several genetic mutations have been identified that cause different forms of dystonia. In some individuals, these genetic mutations result in spasmodic dysphonia, either with no other signs of dystonia or as part of a broader dystonia phenotype. Thus, research in the growing field of dystonia genetics may help to inform our understanding of the pathogenesis of spasmodic dysphonia.

  12. Recurrent laryngeal nerve pathology in spasmodic dysphonia.

    1978-08-01

    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.

    Objective The effect of botulinum toxin among patients with adductor spasmodic dysphonia (AdSD) is temporary. To optimize long-term treatment outcome, other therapy options should be evaluated. Alternative treatment options for AdSD comprise several surgical treatments, such as thyroarytenoid myotomy, thyroplasty, selective laryngeal adductor denervation-reinnervation, laryngeal nerve crush, and recurrent laryngeal nerve resection. Here, we present the first systematic review comparing the effect of botulinum toxin with surgical treatment among patients diagnosed with AdSD. Data Sources MEDLINE (PubMed), EMBASE, and the Cochrane Library. Methods Articles were reviewed by 2 independent authors, and data were compiled in tables for analysis of the objective outcome (voice expert evaluation after voice recording), the subjective outcome (patient self-assessment scores), and voice-related quality of life (Voice Health Index scores). Results No clinical trials comparing both treatment modalities were identified. Single-armed studies evaluated either the effect of botulinum toxin or surgical treatment. Thirteen studies reported outcomes after botulinum toxin treatment (n = 419), and 9 studies reported outcomes after surgical treatment (n = 585 patients). A positive effect of bilateral botulinum toxin injections was found for the objective voice outcome, subjective voice outcome, and quality of life. The duration of the beneficial effect ranged from 15 to 18 weeks. Surgical treatment had an overall positive effect on objective voice improvement, subjective voice improvement, and quality of live. Conclusion No preference for one treatment could be demonstrated. Prospective clinical trials comparing treatment modalities are recommended to delineate the optimal outcomes by direct comparison.

    Spasmodic dysphonia (SD) is a task-specific focal dystonia of unknown pathophysiology, characterized by involuntary spasms in the laryngeal muscles during speaking. Our aim was to identify symptom-specific functional brain activation abnormalities in adductor spasmodic dysphonia (ADSD) and abductor spasmodic dysphonia (ABSD). Both SD groups showed increased activation extent in the primary sensorimotor cortex, insula, and superior temporal gyrus during symptomatic and asymptomatic tasks and decreased activation extent in the basal ganglia, thalamus, and cerebellum during asymptomatic tasks. Increased activation intensity in SD patients was found only in the primary somatosensory cortex during symptomatic voice production, which showed a tendency for correlation with ADSD symptoms. Both SD groups had lower correlation of activation intensities between the primary motor and sensory cortices and additional correlations between the basal ganglia, thalamus, and cerebellum during symptomatic and asymptomatic tasks. Compared with ADSD patients, ABSD patients had larger activation extent in the primary sensorimotor cortex and ventral thalamus during symptomatic task and in the inferior temporal cortex and cerebellum during symptomatic and asymptomatic voice production. The primary somatosensory cortex shows consistent abnormalities in activation extent, intensity, correlation with other brain regions, and symptom severity in SD patients and, therefore, may be involved in the pathophysiology of SD.

    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.

    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.

    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.

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

    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.

    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.

    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.

    Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS.

    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. We used positron emission tomography with the radioligand [(11)C]raclopride (RAC) to study striatal dopaminergic neurotransmission at the resting state and during production of symptomatic sentences and asymptomatic finger tapping in spasmodic dysphonia patients. We found that patients, compared to healthy controls, had bilaterally decreased RAC binding potential (BP) to striatal dopamine D2/D3 receptors on average by 29.2%, which was associated with decreased RAC displacement (RAC ΔBP) in the left striatum during symptomatic speaking (group average difference 10.2%), but increased RAC ΔBP in the bilateral striatum during asymptomatic tapping (group average difference 10.1%). Patients with more severe voice symptoms and subclinically longer reaction time to initiate the tapping sequence had greater RAC ΔBP measures, while longer duration of spasmodic dysphonia was associated with a decrease in task-induced RAC ΔBP. Decreased dopaminergic transmission during symptomatic speech production may represent a disorder-specific pathophysiological trait involved in symptom generation, whereas increased dopaminergic function during unaffected task performance may be explained by a compensatory adaptation of the nigrostriatal dopaminergic system possibly due to decreased striatal D2/D3 receptor availability. These changes can be linked to the clinical and subclinical features of spasmodic dysphonia and may represent the neurochemical basis of basal ganglia alterations in this disorder.

    This article is a compilation of own research performed during the European COoperation in Science and Technology (COST) action 2103: 'Advance Voice Function Assessment', an initiative of voice and speech processing teams consisting of physicists, engineers, and clinicians. This manuscript concerns analyzing largely irregular voicing types, namely substitution voicing (SV) and adductor spasmodic dysphonia (AdSD). A specific perceptual rating scale (IINFVo) was developed, and the Auditory Model Based Pitch Extractor (AMPEX), a piece of software that automatically analyses running speech and generates pitch values in background noise, was applied. The IINFVo perceptual rating scale has been shown to be useful in evaluating SV. The analysis of strongly irregular voices stimulated a modification of the European Laryngological Society's assessment protocol which was originally designed for the common types of (less severe) dysphonia. Acoustic analysis with AMPEX demonstrates that the most informative features are, for SV, the voicing-related acoustic features and, for AdSD, the perturbation measures. Poor correlations between self-assessment and acoustic and perceptual dimensions in the assessment of highly irregular voices argue for a multidimensional approach.

    Speech-related changes in regional cerebral blood flow (rCBF) were measured using H(2)(15)O positron-emission tomography in 9 adults with adductor spasmodic dysphonia (ADSD) before and after botulinum toxin (BTX) injection and 10 age- and gender-matched volunteers without neurological disorders. Scans were acquired at rest and during production of continuous narrative speech and whispered speech. Speech was recorded during scan acquisition for offline quantification of voice breaks, pitch breaks, and percentage aperiodicity to assess correlations between treatment-related changes in rCBF and clinical improvement. Results demonstrated that speech-related responses in heteromodal sensory areas were significantly reduced in persons with ADSD, compared with volunteers, before the administration of BTX. Three to 4 weeks after BTX injection, speech-related responses were significantly augmented in these regions and in left hemisphere motor areas commonly associated with oral-laryngeal motor control. This pattern of responses was most strongly correlated with the objective measures of clinical improvement (decreases in the frequency of voice breaks, pitch breaks, and percentage aperiodicity). These data suggest a pathophysiological model for ADSD in which BTX treatment results in more efficient cortical processing of sensory information, making this information available to motor areas that use it to more effectively regulate laryngeal movements.

    Tremor, affecting a dystonic body part, is a frequent feature of adult-onset dystonia. However, our understanding of dystonic tremor pathophysiology remains ambiguous as its interplay with the main co-occurring disorder, dystonia, is largely unknown. We used a combination of functional MRI, voxel-based morphometry and diffusion-weighted imaging to investigate similar and distinct patterns of brain functional and structural alterations in patients with dystonic tremor of voice (DTv) and isolated spasmodic dysphonia (SD). We found that, compared to controls, SD patients with and without DTv showed similarly increased activation in the sensorimotor cortex, inferior frontal (IFG) and superior temporal gyri, putamen and ventral thalamus, as well as deficient activation in the inferior parietal cortex and middle frontal gyrus (MFG). Common structural alterations were observed in the IFG and putamen, which were further coupled with functional abnormalities in both patient groups. Abnormal activation in left putamen was correlated with SD onset; SD/DTv onset was associated with right putaminal volumetric changes. DTv severity established a significant relationship with abnormal volume of the left IFG. Direct patient group comparisons showed that SD/DTv patients had additional abnormalities in MFG and cerebellar function and white matter integrity in the posterior limb of the internal capsule. Our findings suggest that dystonia and dystonic tremor, at least in the case of SD and SD/DTv, are heterogeneous disorders at different ends of the same pathophysiological spectrum, with each disorder carrying a characteristic neural signature, which may potentially help development of differential markers for these two conditions.

    DYT6 is a primary, early-onset torsion dystonia; however, unlike in DYT1 dystonia, the symptoms of DYT6 dystonia frequently involve the craniocervical region. Recently, two mutations in THAP1, the gene that encodes THAP (thanatos-associated protein) domain-containing apoptosis-associated protein 1 (THAP1), have been identified as a cause of DYT6 dystonia. We screened THAP1 by sequence analysis and quantitative real-time polymerase chain reaction (PCR) in 160 white patients of European ancestry who had dystonia with an early age at onset (n=64), generalised dystonia (n=35), a positive family history of dystonia (n=56), or facial or laryngeal dystonia. Another 160 patients with dystonia were screened for reported and novel variants in THAP1. 280 neurologically healthy controls were screened for the newly identified and previously reported changes in THAP1 and these and an additional 75 controls were screened for a rare non-coding mutation. We identified two mutations in THAP1 (388_389delTC and 474delA), respectively, in two (1%) German patients from the 160 patients with dystonia. Both mutation carriers had laryngeal dystonia that started in childhood and both went on to develop generalised dystonia. Thus, two of three patients with early-onset generalised dystonia with orobulbar involvement had mutations in THAP1. One of the identified patients with DYT6 dystonia had two family members with subtle motor signs who also carried the same mutation. A rare substitution in the 5'untranslated region (-236_235GA-->TT) was found in 20 of 320 patients and in seven of 355 controls (p=0.0054). Although mutations in THAP1 might have only a minor role in patients with different, but mainly focal, forms of dystonia, they do seem to be associated with early-onset generalised dystonia with spasmodic dysphonia. This combination of symptoms might be a characteristic feature of DYT6 dystonia and could be useful in the differential diagnosis of DYT1, DYT4, DYT12, and DYT17 dystonia. In

    Glyphosate is a commonly used nonselective herbicide which inhibits plant growth through interference with the production of essential aromatic amino acids. Toxicity for humans has been reported after suicidal ingestion. Here we describe a 26-year-old teacher who used glyphosate correctly but suffered from severe dysphonia after some hours. Laryngostroboscopy revealed decreased vocal fold mobility suggesting innervation impairment. The symptoms resolved spontaneously 6 weeks later and vocal fold mobility returned to normal. Glyphosate neurotoxicity has been discussed in the literature therefore, the dysphonia observed here may have been due to an intermittent neuropraxia of the laryngeal nerve. However, to our knowledge a similar case has not been reported in literature.

    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.

    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.

    Vocal symptoms are common among the pediatric population and are often caused by vocal abuse. Laryngoscopy is essential for their diagnosis because it helps differentiate several laryngeal lesions, leading to a decision for suitable treatments considering each case. This study aims to present the clinical characteristics, and the laryngoscopic diagnosis of a dysphonic child population. The parents of 304 children, aged from 4 to 18 years and presenting prolonged hoarseness, answered a questionnaire about their children's voice, and all children were subjected to videolaryngostroboscopy. Male children aged from 7 to 12 years (64%) were predominant. Vocal abuse (n-162) and nasal obstruction symptoms (n-10) were the most frequent associated symptoms. The vocal symptoms had a chronic evolution (over 1 year) and were reported by most parents (n-200). The most commonly diagnosed lesions in the laryngoscopic exams were vocal nodules (n-175) and epidermal cysts (n-47). Furthermore, there was an association of some lesions, especially minor structural alterations. In the present study, dysphonia occurred mainly in children aged from 7 to 12 years, predominantly males. Vocal abuse and nasal obstruction symptoms were frequently reported. Vocal nodules and cysts were the most commonly diagnosed laryngeal lesions in the laryngoscopic exams. Copyright © 2012 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    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.

  7. Spasmodic torticollis: a behavioral perspective

    1982-06-01

    The literature on spasmodic torticollis is critically reviewed. The currently most popular etiological hypothesis characterizes torticollis as an extrapyramidal disorder, the symptoms of which are aggravated by stress, but there is no unequivocal evidence available to support this view. Psychological mechanisms have been suggested but not elaborated or tested in any detail. A wide range of treatments has been advocated but controlled studies have not been reported, and the problems of assessing outcome have never been tackled adequately. Behavioral treatments have been evaluated more rigorously than other approaches (particularly EMG feedback training), and the literature suggests that they benefit some patients. It is argued that psychologists have the potential for making a very significant contribution to the understanding and management of torticollis. In discussing outcome measures, the more promising techniques that have been used are summarized and a list is presented of the factors which must be considered when assessing torticollis symptoms. Directions for future research are outlined and priorities suggested.

    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.

    Dysphonia is common in children, but practice varies considerably regarding what, if any, investigations are performed and how the condition is managed. Although childhood dysphonia is mostly due to non-serious causes such as voice misuse, very serious pathology such as papillomatosis or malignancy needs occasionally to be excluded, and treatable congenital anomalies such as webs and cysts can be missed. Voice clinics and voice therapy services are now well established in most adult health services in the developed world, but equivalent services for children are less common, at least in the UK. We retrospectively reviewed the records of all children presenting to our large children's hospital with a primary complaint of dysphonia between January 2001 and October 2007, in order to determine their management, investigations and final diagnosis. We identified 142 children. Case records were found for 137 (97 per cent). Eight-three children were male (61 per cent) and 54 female (39 per cent). Ages ranged from two months to 15 years (median 5.3 years). In 10 children (7 per cent), hoarseness was congenital, presenting as a hoarse, weak cry at birth. In 15 children (11 per cent), onset of hoarseness was related to a specific surgical procedure. The larynx was visualised by mirror alone in 23 children (17 per cent), by awake fibre-optic laryngoscopy in 27 (20 per cent) and by microlaryngoscopy-bronchoscopy under anaesthesia in 42 (31 per cent). Forty children (29 per cent) did not undergo laryngeal visualisation at any time and were diagnosed based on history alone. A further five (4 per cent) were scheduled for direct laryngoscopy but this was not performed due to resolution of symptoms. Voice abuse accounted for 62 (45 per cent) of all diagnoses. Childhood dysphonia accounts for a large number of referrals. There is considerable variation in how these children are managed. A more structured approach to diagnosis and investigation would be beneficial, perhaps within the

    Chronic childhood dysphonia is a common condition in the school-age period. Perceived functional disorder is subjective and the alert is usually given by a person not belonging to the child's immediate environment. History-taking often suggests a malformation or acquired lesion. Functional assessment helps measure and diagnose the vocal impairment. Physical and endoscopic assessment in consultation is the key examination: it is only rarely impossible in children and can often found diagnosis. Additional examinations are sometimes necessary.

    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.

    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.

    Because voice disorders in childhood may have a negative impact on communicative effectiveness, social development, and self-esteem, the objective was to determine the impact of voice disorders on lives of children from the perspective of chronically dysphonic children and their parents. This study consisted of focused interviews with chronically dysphonic children and their caregivers. Focused interviews were conducted with 10 children in each of the following age groups: Toddler (2-4 years old), Young Child (5-7 years old), School-Aged Child (8-12 years old), and Adolescent (13-18 years old). Interview questions were formulated to elicit attitudes in the following conceptual domains: emotional, social/functional, and physical. Interviews were transcribed and subjected to systematic qualitative analyses that identified common themes within each age group for each conceptual domain. For Toddlers, interviews relied heavily on parents and the biggest concerns were found in the physical and functional domains. Young Children expressed that their biggest issues related to voice were physical ("run out of air," "sometimes voice does not work"). Ninety percent of Young Children were repeatedly asked to use a quieter voice. Emotional factors and physical factors were prominent in the interviews of School-Aged Children and Adolescents. Children and Adolescents often felt that their dysphonic voice received undue attention and also limited their participation in important events. Anger, sadness, and frustration were also expressed. Chronic dysphonia negatively affects the lives of children. This work will serve as the basis for development of a valid, reliable, and age-appropriate measure of voice-related quality of life in children.

    Assessing dysphonic symptoms is a noninvasive and effective approach to detect Parkinson's disease (PD) in patients. The main purpose of this study is to investigate the effect of different dysphonia measurements on PD detection by support vector machine (SVM). Seven categories of dysphonia measurements are considered. Experimental results from ten-fold cross-validation technique demonstrate that vocal fundamental frequency statistics yield the highest accuracy of 88 % ± 0.04. When all dysphonia measurements are employed, the SVM classifier achieves 94 % ± 0.03 accuracy. A refinement of the original patterns space by removing dysphonia measurements with similar variation across healthy and PD subjects allows achieving 97.03 % ± 0.03 accuracy. The latter performance is larger than what is reported in the literature on the same dataset with ten-fold cross-validation technique. Finally, it was found that measures of ratio of noise to tonal components in the voice are the most suitable dysphonic symptoms to detect PD subjects as they achieve 99.64 % ± 0.01 specificity. This finding is highly promising for understanding PD symptoms.

    The hip adductor group, innervated predominantly by the obturator nerve, occupies a large volume of the lower limb. However, case reports of patients with obturator nerve palsy or denervation have described no more than minimal gait disturbance. Those facts are surprising, given the architectural characteristics of the hip adductors. Our aim was to investigate which regions of the adductor magnus are innervated by the obturator nerve and by which sciatic nerve and to consider the clinical implications. Twenty-one lower limbs were examined from 21 formalin-fixed cadavers, 18 males and 3 females. The adductor magnus was dissected and was divided into four parts (AM1-AM4) based on the locations of the perforating arteries and the adductor hiatus. AM1 was supplied solely by the obturator nerve. AM2, AM3, and AM4 received innervation from both the posterior branch of the obturator nerve and the tibial nerve portion of the sciatic nerve in 2 (9.5%), 20 (95.2%), and 6 (28.6%) of the cadavers, respectively. The double innervation in more than 90% of the AM3s is especially noteworthy. Generally, AM1-AM3 corresponds to the adductor part, traditionally characterized as innervated by the obturator nerve, and AM4 corresponds to the hamstrings part, innervated by the sciatic nerve. Here, we showed that the sciatic nerve supplies not only the hamstrings part but also the adductor part. These two nerves spread more widely than has generally been believed, which could have practical implications for the assessment and treatment of motor disability.

    To consider the feasibility of diagnosing intrinsic laryngeal muscle myofascial pain syndrome (MPS) in dysphonic patients who demonstrated immediate symptom and stroboscopic finding improvement after laryngeal electromyography (LEMG) without further treatment. A chart review of patients who showed subtle vocal fold movement abnormalities on a stroboscopic examination and underwent ultrasonography (US)-guided LEMG was performed. Patients with vocal fold paralysis, mucosal lesions, spasmodic dysphonia, and vocal tremor on stroboscopic examination were excluded. Among them, patients with normal EMG findings were included in this study. The patients who reported voice symptom improvement after LEMG without further treatment were placed in laryngeal MPS (LMPS) group and the other patients were placed in non-laryngeal MPS (non-MPS) group. Predisposing factors, voice symptom, symptom-duration, and stroboscopic findings of these patients were reviewed. Among the 16 patients, LEMG findings were normal, five (31%) were included in the LMPS group and the other 11 patients (69%) were included in the non-MPS group. All LMPS group patients had a history of voice abuse and reported odynophonia. The Korean Voice Handicap Index-10 score decreased significantly after US-guided LEMG without additional treatment in the LMPS group. The stroboscopic findings revealed that vocal fold hypomobility was the most common finding in the LMPS group, and two patients showed a muscle tension dysphonia pattern. The LMPS groups showed improvement of vocal fold mobility on 1-week stroboscopic evaluation. LMPS is a potential diagnosis for patients with vocal fold hypomobility finding on stroboscopic findings but with normal EMG results. Diagnosis of LMPS could be considered in patients who showed symptom and vocal fold movement improvement after LEMG. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    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.)

In numerous studies of the analgesic effect of the so-called adductor canal block for total knee arthroplasty, the needle insertion point has been the midpoint of the thigh......, determined as the midpoint between the anterior superior iliac spine and base of patella. "Adductor canal block" may be a misnomer for an approach that is actually an injection into the femoral triangle, a "femoral triangle block." This block probably has a different analgesic effect compared...... with an injection into the adductor canal. We sought to determine the exact location of the adductor canal using ultrasound and relate it to the midpoint of the thigh. METHODS: Twenty-two volunteers were examined using ultrasound. The proximal end of the adductor canal was identified where the medial border...

    Acute adductor longus ruptures occur infrequently and have been rarely described in the literature. Schlegel et al. reviewed a series of adductor longus tendon ruptures and found that all ruptured proximally. A 42-year-old man with right hip pain 3 weeks following a skiing injury underwent magnetic resonance imaging (MRI), which demonstrated a distal adductor longus avulsion. The diagnosis of acute adductor longus injury can be difficult on physical examination alone, but MRI can accurately depict the site of injury. Surgery may be indicated for a proximal avulsion, but a distal injury may heal with nonoperative treatment, as in our case. Copyright © 2016 Elsevier Inc. All rights reserved.

    The exact homologies of tetrapod jaw muscles remain unresolved, and this provides a barrier for phylogenetic analysis and tracing character evolution. Here, lepidosaur jaw muscles are surveyed using direct examination of species from 23 families and published descriptions of species from 10 families. A revised nomenclature is applied according to proposed homologies with Latimeria. Among lepidosaurs, variation was found in many aspects of jaw muscle anatomy. The superficial layers mm. levator and retractor anguli oris (LAO and RAO) are present in Sphenodon but not all squamates. The external jaw adductor muscles universally present in lepidosaurs are homologous with the main adductor muscle, A2, of Latimeria and include four layers: superficialis (A2-SUP), medialis (A2-M), profundus (A2-PRO), and posterior (A2-PVM). The A2-SUP appears divided in Agamidae, Gekkota, Xantusiidae, and Varanidae. The A2-M is layered lateromedial in lizards but anteroposterior in snakes. The names pseudotemporalis (PS) and pterygomandibularis (PTM) are recommended for subdivisions of the internal adductors of reptiles and amphibians, because the homology of this muscle with the A3' and A3 ″ of Latimeria remains inconclusive. The intramandibularis of lepidosaurs and Latimeria (A-ω) are homologous. The distribution of six jaw muscle characters was found to plot more parsimoniously on phylogenies based on morphological rather than and molecular data. Character mapping indicates that Squamata presents reduction in the divisions of the A2-M, Scincoidea presents reduction or loss of LAO, and two apomorphic features are found for the Gekkota.

    Chronic groin pain in the athlete can be a difficult problem to manage. Adductor dysfunction is the most common cause of groin pain in athletes, with the adductor longus being the tendon most commonly involved. The most reproducible finding for adductor longus tendinopathy is tenderness along the tendon with passive abduction and resisted hip adduction in extension. Magnetic resonance imaging and injection of a corticosteroid and anesthetic into the proximal muscle-tendon junction are both helpful in confirming the diagnosis. Nonoperative treatment may consist of protected weight bearing, ice application, ultrasonography, electrical stimulation, and gentle stretching with progressive strengthening. However, nonoperative management is not always successful. In these instances, surgical treatment can be quite effective. We present the indications, surgical technique, and rehabilitation protocol of adductor tenotomy for chronic tendinopathy. This can prove a useful tool for the treatment of recalcitrant groin pain attributable to the adductor longus.

    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.

    To study the gender differences of amount of neurons in the nodose ganglions of rats. Fourteen Sprague-Dawley rats (7 males and 7 females) were selected. Bilateral nodose ganglions were dissected and serial sections of nodose ganglion were cut in a cryostat, followed by Cresyl-violet staining for neurons. Eight to ten consecutive sections from mid-portion of each nodose ganglion sample, which represent the most neuron number per section, were counted and averaged. Gender difference in the amount of neurons in the nodose ganglions was compared. No gender difference of neuron numbers was found in either side of nodose ganglion (p > 0.05). However, average neuron number of nodose ganglions on the left side of male (654 ± 60) and female (616 ± 37) were significantly more than that on the right side of male (470 ± 22) and female (453 ± 40) respectively (p < 0.05). There is no gender difference in total neuron number of nodose ganglions between male and female rat. However, the neuron number in the left nodose ganglion is greater than that in the right one. The difference may be due to the fact that left and right nodose ganglion is receiving different visceral sensory impulses separately, which is associated with different physiological functions. Further work should be carried out with retrograde tracing on neurons of nodose ganglions in an animal model, which are directly related to laryngeal sensory transmission, in order to determine the gender difference in the neuron number and morphology related to laryngeal functions.

    Full Text Available Introduction: Adductor spasticity at hips is the main barrier in functional activities and rehabilitation of spastic cerebral palsy patients. The aim of this study is to evaluate the results of percutaneous adductor release under general anesthesia. Methods: From July 2005 to July 2010, 64 hips in 32 patients (19 males and 13 females were recruited from outpatient department having adductor contracture at hips in cerebral palsy children. All children were operated under general anesthesia. All children were followed for twenty-four months. The clinical results were evaluated radiologically, including measurement of CE- angle, AC-index and femoral head coverage and in terms of activity level of children. Results: Of the thirty-two children, twenty-eight showed marked and immediate improvement. None of our children was functionally worse at follow-up. The CE-angle and femoral head coverage did not change significantly. The AC-index improved significantly (p = 0.01.The results were excellent in 12.5% children, good in 50%, fair in 25% and poor in 12.5%. Conclusions: Bilateral mini-invasive adductor release can be an effective treatment for children suffering from adductor contracture refractory to nonoperative management and early adductor release can prevent subluxation and possibly the need for future bony procedure on the proximal femur and pelvis.

    2014-03-01

    An incarcerated inguinal hernia is a common diagnosis, since the risk of an inguinal hernia incarcerating or strangulating is around 0.3-3%. An acute rupture of the adductor longus tendon is rarely seen and mostly affects (semi-) professional sportsmen. We present a case of a patient with an assumed incarcerated inguinal hernia which turned out to be a proximal adductor longus tendon rupture. If patients without a history of inguinal hernia present themselves with acute groin pain after suddenly exorotating the upper leg, a rupture of the adductor longus tendon should be considered. Both surgical and non-surgical treatment can be performed.

    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.

    1988-03-01

    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.

    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 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.

    Full Text Available Eighty-five patients with idiopathic spasmodic torticollis were compared with an equally chronic group of 49 cervical spondylosis sufferers in terms of body concept, depression, and disability. The torticollis patients were significantly more depressed and disabled and had a more negative body concept. Depression had different determinants in the two groups. Extent of disfigurement was a major predictor of depression in torticollis. Neuroticism accounted for the greatest proportion of the variance of depression in cervical spondylosis.

    Background: Theoretically, the ideal volume of local anaesthetic for adductor canal block (ACB) would ensure sufficient filling ofthe canal and avoid proximal spread to the femoral triangle. In this dose-finding study, we aimed to investigate the minimaleffective volume for an ACB needed to fill...... the adductor canal distally in at least 95% of patients (ED95). Methods: We performed a blinded trial, enrolling 40 healthy men. All subjects received an ACB with lidocaine 1%. Volumes wereassigned sequentially to the subjects using the continual reassessment method followed by Bayesian analysis to determine...... theED95. Distal filling of the adductor canal was assessed by magnetic resonance imaging (primary outcome). Secondary outcomeswere the effect of volume on proximal spread to the femoral triangle (also assessed by magnetic resonance imaging), quadricepsmuscle weakness (decrease by ≥25% from baseline...

    We present a rare case of spontaneous rupture of the adductor longus tendon induced by ciprofloxacin. 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.

    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.

    Functional dysphonia (FD) refers to a voice problem in the absence of a physical condition. 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. An international multicentric effort, involving a large population of voice-disordered patients with no physical pathology, could produce enough data for

    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.

    Dysphonia is a potential long-term complication of preterm birth. Childhood voice disorders caused by vocal hyperfunction resolve with pubertal changes to the vocal mechanism in many cases. In extremely preterm children, whose voice quality is affected by supraglottic hyperfunction adapted secondary to underlying structural laryngeal pathology sustained during neonatal intubation, the prognosis is unknown. A pilot study was conducted to assess the incidence and severity of dysphonia in children born at dysphonia severity scores were significantly lower on repeat assessment, but no differences were observed in objective or quality of life scores. Individual variation was observed: the difference in CAPE-V scores ranged from -36 to + 1. No participant presented with normal voice quality on repeat assessment. Analysis of group data masked individual variability in this series. Mechanisms underlying such individual variation are currently unknown. These data suggest that dysphonia is persistent in extremely preterm children. Further investigation is warranted to elucidate the progression of voice disorders in extremely preterm children, to inform prognostic predictors and treatment decisions.

    Full Text Available [b]introduction[/b]. In a group of persons using the voice occupationally, the frequent symptoms are hoarseness, voice fatigability and aphonia. 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 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.

    Acute adductor injuries account for the majority of acute groin injuries; however, little is known about specific injury characteristics, which could be important for the understanding of etiology and management of these injuries. The study aim was to describe acute adductor injuries in athletes using magnetic resonance imaging (MRI). Male athletes with acute groin pain and an MRI confirmed acute adductor muscle injury were prospectively included. MRI was performed within 7 days of injury using a standardized protocol and a reliable assessment approach. 156 athletes presented with acute groin pain of which 71 athletes were included, median age 27 years (range 18-37). There were 46 isolated muscle injuries and 25 athletes with multiple adductor injuries. In total, 111 acute adductor muscle injuries were recorded; 62 adductor longus, 18 adductor brevis, 17 pectineus, 9 obturator externus, 4 gracilis, and 1 adductor magnus injury. Adductor longus injuries occurred at three main injury locations; proximal insertion (26%), intramuscular musculo-tendinous junction (MTJ) of the proximal tendon (26%) and the MTJ of the distal tendon (37%). Intramuscular tendon injury was seen in one case. At the proximal insertion, 12 of 16 injuries were complete avulsions. This study shows that acute adductor injuries generally occur in isolation from other muscle groups. Adductor longus is the most frequently injured muscle in isolation and in combination with other adductor muscle injuries. Three characteristic adductor longus injury locations were observed on MRI, with avulsion injuries accounting for three-quarters of injuries at the proximal insertion, and intramuscular tendon injury was uncommon. © 2017 John Wiley & Sons A/S.

    Full Text Available We reconstructed the jaw adductor resultant in 34 primate species using new data on muscle physiological cross-sectional area (PCSA and data on skull landmarks. Based on predictions by Greaves, the resultant should (1 cross the jaw at 30% of its length, (2 lie directly posterior to the last molar, and (3 incline more anteriorly in primates that need not resist large anteriorly-directed forces. We found that the resultant lies significantly posterior to its predicted location, is significantly posterior to the last molar, and is significantly more anteriorly inclined in folivores than in frugivores. Perhaps primates emphasize avoiding temporomandibular joint distraction and/or wide gapes at the expense of bite force. Our exploration of trends in the data revealed that estimated bite force varies with body mass (but not diet and is significantly greater in strepsirrhines than in anthropoids. This might be related to greater contribution from the balancing-side jaw adductors in anthropoids.

    Rodríguez, Hugo; Cuestas, Giselle; Zanetta, Adrián

    2013-01-01

    Dysphonia is common in children. Its main cause is the abuse or misuse of the voice. Congenital, neoplastic, infectious, neurological or iatrogenic causes are less frequent. The laryngeal web is a rare congenital anomaly resulting from an incomplete recanalization of the primitive larynx. This condition should be suspected in any newborn with dysphonic cry with or without stridor and respiratory distress. The diagnosis is confirmed by endoscopic examination. Therapy depends on the extent and thickness of the membrane and the severity of the symptoms. We describe our experience with 8 patients suffering this condition, and we emphasize the need to recognize voice disorders and to evaluate the airway for accurate diagnosis and appropriate treatment in every newborn, infant or child with persistent dysphonia.

    To suggest a phonosurgical management strategy that can be used for children who have previously undergone laryngotracheal reconstruction. This cases series describes three children who presented with complex, multi-level airway stenosis and marked dysphonia. Phonosurgical intervention involved endoscopic and open approaches, and was combined with voice therapy. A phonosurgical reconstruction management algorithm is suggested for evaluating and treating these complex conditions. Pre-operative assessment is critical, and should involve voice analysis and glottal anatomy assessment using office laryngoscopy and stroboscopy. The risks must be weighed up against the benefit of vocal improvement. Surgical intervention should involve combined endoscopic and open approaches. Voice restoration after paediatric airway reconstruction is a complex challenge. Surgical intervention should be conducted in a step-by-step manner to reduce the risk of worsening dysphonia and airway compromise. The risks and benefits must be carefully explored and discussed.

    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 Objectives: This study determined the prevalence of vocal nodules associated with dysphonia in teachers aged from 35 to 65 years, taking into consideration both individual and occupational variables. Methodology: Descriptive study that included the information contained in 262 medical records of teachers diagnosed with dysphonia in occupational health consultations at the institutions that provide health services in Bogotá, Colombia from March 2009 to March 2012. The presence of laryngeal nodules was based on the findings of a nasofibrolaryngoscopy procedure. Results: Nodules were found in 67 teachers, which corresponded to a rate of 25.5%, being apparently (highest observed rates associated primarily with the following variables: females, ages from 45 to 54 years, bilateral nodules, and teaching position (preschool and physical education. Of the teachers with nodules, 76.1% had fewer than five doctor's appointments, and 75% had more than 90 days of sick leave. Conclusion: A high percentage of teachers have vocal nodules associated with dysphonia. This may be apparently related to different variables such as sex, type of nodule, area and teaching position. Was observed only a statistically significant association among presence of nodules and age (p=0.018. In addition this disorder generates a large number of incapacities and employee absenteeism.

    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.

  2. 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.

    There is only very limited information on the prevalence of voice disorders, particularly for the pediatric population. This study examined the prevalence of dysphonia in a large cohort of children (n = 7389) at 8 years of age. Data were collected within a large prospective epidemiological study and included a formal assessment by one of five research speech and language therapists as well as a parental report of their child's voice. Common risk factors that were also analyzed included sex, sibling numbers, asthma, regular conductive hearing loss, and frequent upper respiratory infection. The research clinicians identified a dysphonia prevalence of 6% compared with a parental report of 11%. Both measures suggested a significant risk of dysphonia for children with older siblings. Other measures were not in agreement between clinician and parental reports. The clinician judgments also suggested significant risk factors for sex (male) but not for any common respiratory or otolaryngological conditions that were analyzed. Parental report suggested significant risk factors with respect to asthma and tonsillectomy. These results are discussed in detail.

    This study's objectives are to 1) to assess the prevalence of dysphonia in the primary care community, 2) evaluate the severity of dysphonia, 3) explore potential risk factors for dysphonia, 4) examine the treatment of dysphonic patients, and 5) assess treatment-related barriers. The hypotheses are that 1) dysphonia is common in the primary care community, 2) it adversely impacts patients' quality of life (QOL), and 3) patients are underevaluated and experience obstacles with respect to seeking treatment. Cross-sectional, practice-based study in the primary care population. English-speaking patients 18 years of age and older were recruited from a primary care research network. Patients presenting to their primary care practices were given a packet of questionnaires to complete that documented demographic information, risk factors, presence of dysphonia, prior treatment, and reasons for not seeking treatment. The Voice-Related Quality of Life (VRQOL) and Center for Epidemiological Studies-Depression Scale (CES-D) served as quality-of-life outcome measures. A priori sample size calculations were performed indicating a sample size of 780. Univariate analyses, descriptive statistics, odds ratios and 95% confidence intervals, and multivariate analyses were performed. A total of 789 patients with a mean age of 49.9 years and range of 18 to 94 years participated. Lifetime prevalence of dysphonia was 29.1%, point prevalence of dysphonia 7.5%, and 4.3% had had dysphonia for >4 weeks. Of those with current dysphonia, only 46% had not missed work. Of those with current dysphonia, 73.3% had had dysphonia more than once. Patients with dysphonia had lower VRQOL scores and higher CES-D scores (t test, P ≤.001). Risk factors for dysphonia and impaired VRQOL on multivariate analysis included neurologic disease, dry mouth, family history of dysphonia, college or postgraduate level education, allergies or sinus problems, neck pain, medication for depression/anxiety, more than three

    Full Text Available Spasticity is motor alteration characterized by muscle hypertonia and hyperreflexia. It is an important complication of spinal cord injury, traumatic brain injury, cerebral palsy, and multiple sclerosis. If uncorrected, fibrosis and eventually bony deformity lock the joint into a fixed contracture. Chemical neurolysis using various agents is one of the therapeutic possibilities to alleviate spasticity. We are, hereby, reporting 3 patients in whom 65% alcohol was used as neurolytic agent for the treatment of hip adductor spasticity, and the effect lasted for a variable period.

    Muscle strain of the lower extremities is among the most common injuries in sports. Excessive force, rather than direct trauma, causes disruption of the muscle-tendon unit, usually at the myotendinous junction, and improper rest and rehabilitation of a minor strain can often lead to a far more disabling injury. High-resolution ultrasonography is useful for direct imaging of muscle injuries. We present a case where ultrasonography was used to detect, treat and follow-up an adductor longus tear in a soccer player. (author)

    The problem of the late accretion phase of the evolution of an axisymmetric, isothermal magnetic disk surrounding a forming star has been formulated in a companion paper. The ``central sink approximation'' is used to circumvent the problem of describing the evolution inside the opaque central region for densities greater than 1011 cm-3 and radii smaller than a few AU. Only the electrons are assumed to be attached to the magnetic field lines, and the effects of both negatively and positively charged grains are accounted for. After a mass of 0.1 Msolar accumulates in the central cell (forming star), a series of magnetically driven outflows and associated outward-propagating shocks form in a quasi-periodic fashion. As a result, mass accretion onto the protostar occurs in magnetically controlled bursts. We refer to this process as spasmodic accretion. The shocks propagate outward with supermagnetosonic speeds. The period of dissipation and revival of the outflow decreases in time, as the mass accumulated in the central sink increases. We evaluate the contribution of ambipolar diffusion to the resolution of the magnetic flux problem of star formation during the accretion phase, and we find it to be very significant albeit not sufficient to resolve the entire problem yet. Ohmic dissipation is completely negligible in the disk during this phase of the evolution. The protostellar disk is found to be stable against interchange-like instabilities, despite the fact that the mass-to-flux ratio has temporary local maxima.

    The problem of the late accretion phase of the evolution of an axisymmetric, isothermal magnetic disk surrounding a forming star has been formulated in a companion paper. 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 and radii smaller than a few AUs. Only the electrons are assumed to be attached to the magnetic field lines, and the effects of both negatively and positively charged grains are accounted for. After a mass of 0.1 solar mass accumulates in the central cell (forming star), a series of magnetically driven outflows and associated outward propagating shocks form in a quasi-periodic fashion. As a result, mass accretion onto the protostar occurs in magnetically controlled bursts. We refer to this process as spasmodic accretion. The shocks propagate outward with supermagnetosonic speeds. The period of dissipation and revival of the outflow decreases in time, as the mass accumulated in ...

    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.

    Jaw mechanics in ornithischian dinosaurs have been widely studied for well over a century. Most of these studies, however, use only one or few taxa within a given ornithischian clade as a model for feeding mechanics across the entire clade. In this study, mandibular mechanical advantages among 52 ornithischian genera spanning all subclades are calculated using 2D lever arm methods. These lever arm calculations estimate the effect of jaw shape and difference in adductor muscle line of action on relative bite forces along the jaw. Results show major instances of overlap between taxa in tooth positions at which there was highest mechanical advantage. A relatively low bite force is seen across the tooth row among thyreophorans (e.g., stegosaurs and ankylosaurs), with variation among taxa. A convergent transition occurs from a more evenly distributed bite force along the jaw in basal ornithopods and basal marginocephalians to a strong distal bite force in hadrosaurids and ceratopsids, respectively. Accordingly, adductor muscle vector angles show repeated trends from a mid-range caudodorsal orientation in basal ornithischians to a decrease in vector angles indicating more caudally oriented jaw movements in derived taxa (e.g., derived thyreophorans, basal ornithopods, lambeosaurines, pachycephalosaurs, and derived ceratopsids). Analyses of hypothetical jaw morphologies were also performed, indicating that both the coronoid process and lowered jaw joint increase moment arm length therefore increasing mechanical advantage of the jaw apparatus. Adaptive trends in craniomandibular anatomy show that ornithischians evolved more complex feeding apparatuses within different clades as well as morphological convergences between clades.

    The study was done to prove the etiopathogenetical power of some personality traits, proceeding life events, and strain effects when exposed to an experimental work-stress. 20 functional dysphonics, 14 individuals suffering from organic voice disorders and a group of 20 control persons were examined. The results show that the group of functional dysphonics produced a significant more positive self-evaluation regarding their personality with a clear tendency to restraint. Compared to the control group they showed a higher level of state anxiety in situations causing stress. Furthermore the influence of proceeding life events for the etiopathogenesis of functional dysphonia has become clear.

    Inhalation of a laryngotracheobronchial foreign body is a common pediatric emergency situation. It is a source of morbidity and even mortality, especially among children under 3 years of age. A 14-month-old child presented suddenly combining bitonal dysphonia and dyspnea. Given the persistence of symptoms after 1.5 months and the normality of examinations requested by his doctor (pH, cervical ultrasonography, cervical and thoracic radiography), an ENT opinion was sought. An aerodigestive tract endoscopy was carried out in the emergency setting, finding a glottic foreign body associated with subglottic granulomas. The foreign body extraction led to the immediate disappearance of dyspnea. Dysphonia gradually improved under Budesonide aerosols. The lack of penetration syndrome in the interrogation and non specific symptoms may lead to an important diagnosis and treatment delay with dramatic consequences in case of airway foreign body. Endoscopy under general anesthesia must be practiced if there is any doubt for a thorough examination of the airways. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    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.

  16. Symphysis Pubis Osteomyelitis with Bilateral Adductor Muscles Abscess

    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.

    The composite tissue flap of the descending genicular vessels with the adductor magnus tendon is a newly developed, reliable method to repair the Achilles tendon and relevant skin defects. The aim of this study was to evaluate the anatomy of the adductor magnus tendon-descending genicular artery bone flap, and the feasibility and value for the repair of the Achilles tendon and relevant skin defects. There were 34 adult specimens used for the anatomy of this flap. The descending genicular artery originates 10.5 ± 1.6 cm above the adductor tubercle, with a diameter of 1.8 ± 0.6 mm and a length of 1.2 ± 0.5 cm. Its articular branch is distributed in the adductor magnus tendon and the medial condyle of the femur. The saphenous branch has a diameter of 1.1 ± 0.3 mm and is distributed in the skin of the upper medial calf. A total of 16 cases of trauma-induced Achilles tendon damage and calcaneus and skin defects were repaired with the vascularized adductor magnus tendon bone flap, including the reconstruction of Achilles tendon insertion and repair of relevant skin defects. All of the composite tissue flaps were viable, the skin sensation of the flaps was recovered, and all patients walked with a normal gait. Our results suggested that the adductor magnus tendon-descending genicular artery bone flap is an alternative method to repair composite tissue defects of the Achilles tendon.

    The aim of this study was to examine anatomical properties of the adductor magnus through a detailed classification, and to hypothesize its function and size to gather enough information about morphology. Ten cadaveric specimens of the adductor magnus were used. The muscle was separated into four portios (AM1-AM4) based on the courses of the corresponding perforating arteries, and its volume, muscle length, muscle fiber length and physiological cross-sectional area were assessed. The architectural characteristics of these four portions of the adductor magnus were then classified with the aid of principal component analysis. The results led us into demarcating the most proximal part of the adductor magnus (AM1) from the remaining parts (AM2, AM3, and AM4). Classification of the adductor magnus in terms of architectural characteristics differed from the more traditional anatomical distinction. The AM2, AM3, and AM4, having longer muscle fiber lengths than the AM1, appear to be designed as displacers for moving the thigh through a large range of motion. The AM1 appears instead to be oriented principally toward stabilizing the hip joint. The large mass of the adductor magnus should thus be regarded as a complex of functionally differentiable muscle portions.

    The adductor reflex (AR) is a tendon reflex that has various features that differ from other tendon reflexes. This reflex was tested in different disorders presenting with diminished patellar reflexes such as diabetic lumbosacral radiculoplexus neuropathy (DLRPN), L2-L4 radiculopathy, and distal symmetric diabetic neuropathy (diabetic PNP). The AR and crossed-AR (elicited by tapping the contralateral patellar tendon) were recorded using concentric needle electrodes. Additionally, the patellar T reflex (vm-TR) and vastus medialis H reflex (vm-HR) were recorded using surface electrodes. AR was recorded in only one out of eight patients with DLRPN, but it was recorded in 21 out of 22 patients with L2-L4 radiculopathy (95.5%). Of these reflexes, only AR showed prolonged latency in the L2-L4 radiculopathy group. The latencies of AR, vm-TR, and vm-HR were prolonged in patients with diabetic PNP. We conclude that AR can be useful in the differential diagnosis of some lower motor neuron disorders that present with patellar reflex disturbance. Muscle Nerve 40: 264-270, 2009.

    García-Esponda, César M; Candela, Adriana M

    2015-06-01

    Anatomical comparative studies including myological data of caviomorph rodents are relatively scarce, leading to a lack of use of muscular features in cladistic and morphofunctional analyses. In rodents, the hip adductor muscles constitute an important group of the hindlimb musculature, having an important function during the beginning of the stance phase. These muscles are subdivided in several distinct ways in the different clades of rodents, making the identification of their homologies hard to establish. In this contribution we provide a detailed description of the anatomical variation of the hip adductor muscle group of different genera of caviomorph rodents and identify the homologies of these muscles in the context of Rodentia. On this basis, we identify the characteristic pattern of the hip adductor muscles in Caviomorpha. Our results indicate that caviomorphs present a singular pattern of the hip adductor musculature that distinguishes them from other groups of rodents. They are characterized by having a single m. adductor brevis that includes solely its genicular part. This muscle, together with the m. gracilis, composes a muscular sheet that is medial to all other muscles of the hip adductor group. Both muscles probably have a synergistic action during locomotion, where the m. adductor brevis reinforces the multiple functions of the m. gracilis in caviomorphs. Mapping of analyzed myological characters in the context of Rodentia indicates that several features are recovered as potential synapomorphies of caviomorphs. Thus, analysis of the myological data described here adds to the current knowledge of caviomorph rodents from anatomical and functional points of view, indicating that this group has features that clearly differentiate them from other rodents.

    Neural mechanisms of motor signal transmission in ventrooral (Voi) nucleus of motor thalamus during the realization-of voluntary and involuntary abnormal (dystonic) movements in patients with spasmodic torticollis were investigated by means of microelectrode technique. The high reactivity of the cellular Voi elements to various functional (mainly motor) tests was proved. Analysis of neuronal activity showed: (1) the difference of neural mechanisms of motor signal transmission in the realization of voluntary movement with and without the involvement of the pathological axial neck muscles, as well as passive and abnormal involuntary dystonic movements; (2) significance of sensory component in the mechanisms of sensorimotor interactions during realization of voluntary and involuntary dystonic head and neck movements, causing the activation of the axial neck muscles; (3) important role of the rhythmic and synchronized neuronal activity in motor signal transmission during the realization of active and passive movements. Participation of Voi nucleus in pathological mechanisms of spasmodic torticollis was shown. The data obtained can be used for identificatiori of Voi thalamic nucleus during stereotactic neurosurgical operations in patients with spasmodic torticollis for selection the optimum destruction (stimulation) target and reduction of postoperative effects.

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

    Oskouei, Ali E; Herzog, Walter

    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.

    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.

    Psychogenic dysphonia is a functional disorder with variable clinical manifestations. To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series. 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. 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.

    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.

    Inhibitory glycine receptors (GlyRs) are pentameric ligand gated ion channels composed of α and β subunits assembled in a 2:3 stoichiometry. The α1/βheteromer is considered the dominant GlyR isoform at 'native' adult synapses in the spinal cord and brainstem. However, the α3 GlyR subunit is concentrated in the superficial dorsal horn (SDH: laminae I-II), a spinal cord region important for processing nociceptive signals from skin, muscle and viscera. Here we use the spasmodic mouse, which has a naturally occurring mutation (A52S) in the α1 subunit of the GlyR, to examine the effect of the mutation on inhibitory synaptic transmission and homeostatic plasticity, and to probe for the presence of various GlyR subunits in the SDH.We usedwhole cell recording (at 22-24◦C) in lumbar spinal cord slices obtained from ketamine-anaesthetized (100 mg kg⁻¹, I.P.) spasmodic and wild-type mice (mean age P27 and P29, respectively, both sexes). The amplitude and decay time constants of GlyR mediated mIPSCs in spasmodic micewere reduced by 25% and 50%, respectively (42.0 ± 3.6 pA vs. 31.0 ± 1.8 pA, P spasmodic GlyRs (EC50 =130 ± 20 μM vs. 64 ± 11 μM, respectively; n =8 and 15, respectively). Differential agonist sensitivity and mIPSC decay times were subsequently used to probe for the presence of α1-containing GlyRs in SDHneurones.Glycine sensitivity, based on the response to 1-3 μM glycine, was reduced in>75% of neurones tested and decay times were faster in the spasmodic sample. Together, our data suggest most GlyRs and glycinergic synapses in the SDH contain α1 subunits and few are composed exclusively of α3 subunits. Therefore, future efforts to design therapies that target the α3 subunit must consider the potential interaction between α1 and α3 subunits in the GlyR.

    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.

    Full Text Available Background: Sacroiliac joint dysfunction (SIJD is a common problem that causes pain and disability. Adductor pull back exercise is widely used for treating sacroiliac joint dysfunction. No yet research has been directly examined the efficacy of adductor pull back exercise for sacroiliac joint dysfunction. The purpose of the study to find the efficacy of adductor pull back exercise on pain and functional disability for subjects with sacroiliac joint dysfunction. Methods: An experimental study design, 40 subjects with unilateral Sacroiliac joint dysfunction were randomized into two groups: study group (n=20, and control group (n=20. Subjects in study group received adductor pull back exercise along with conventional exercise and Subjects in control group received conventional exercise. The duration of treatment was given for two weeks, three times a day, total six days per week. Outcome measures such as pain was measured using Visual analog scale (VAS, and functional disability was measured using Oswestry Disability Index questionnaire (ODI before and after 2 weeks of the treatment in both the groups.

    Anterior cervical discectomy (ACD) is widely used for symptomatic cervical spine pathologies. The most common complications associated with this type of surgery are dysphagia and dysphonia; however, the risk factors associated with them have not been adequately elucidated. The purpose of this study is to assess the incidence of self-reported dysphagia and dysphonia and the associated risk factors after ACD. This study used a retrospective chart review of 149 patients who underwent ACD at a tertiary care facility operating in the New York metropolitan area over a period of 2½ years. Charts for ACD patients were reviewed by 6 trained researchers. Incidence rates for self-reported dysphagia and dysphonia were calculated using 95% exact confidence intervals (CI). Risk factors such as age, sex, surgical hours, number of disc levels, airway class, American Society of Anesthesiologists class, fiberoptic intubation, and intubation difficulty were assessed using logistic regression. The incidence of self-reported dysphagia was 12.1% (95% exact CI, 7.3%-18.4%); for dysphonia the self-reported incidence was 5.4% (95% exact CI, 2.3%-10.3%). Patients who underwent surgery at ≥4 cervical levels had a significant 4-fold increased risk (odds ratio=4; 95% CI, 1.1-13.8) of developing dysphonia and/or dysphagia compared with patients who underwent surgery at a single surgical level. This study confirms previous findings that the risk of developing dysphagia and/or dysphonia increases with the number of surgical levels, with multiple cervical levels representing a significantly higher postoperative risk, as compared with surgery at 1 level.

    An adductor canal catheter may facilitate early ambulation after total knee arthroplasty, but there is concern over preoperative placement since intraoperative migration of catheters may occur from surgical manipulation and result in ineffective analgesia. We hypothesized that catheter type and subcutaneous tunneling may influence tip migration for preoperatively inserted adductor canal catheters. In a male unembalmed human cadaver, 20 catheter insertion trials were divided randomly into one of four groups: flexible epidural catheter either tunneled or not tunneled; or rigid stimulating catheter either tunneled or not tunneled. Intraoperative patient manipulation was simulated by five range-of-motion exercises of the knee. Distance and length measurements were performed by a blinded regional anesthesiologist. Changes in catheter tip to nerve distance (p = 0.225) and length of catheter within the adductor canal (p = 0.467) were not different between the four groups. Two of five non-tunneled stimulating catheters (40 %) were dislodged compared to 0/5 in all other groups (p = 0.187). A cadaver model may be useful for assessing migration of regional anesthesia catheters; catheter type and subcutaneous tunneling may not affect migration of adductor canal catheters based on this preliminary study. However, future studies involving a larger sample size, actual patients, and other catheter types are warranted.

    2010-12-01

    Full Text Available Objective: To evaluate and compare the effectiveness of different methods used for nutritional assessment of outpatients who had hemiplegic stroke. Methods: A cross-section study with adult and elderly patients of both genders enrolled in a rehabilitation center. The analyzed variables were anthropometric measurements, bioelectrical impedance, hand grip strength and thickness of the adductor pollicis muscle. The Pearson χ2 test was used to check the association between variables with a significance level of α = 5%. Results: When evaluating the association between indicators of muscle mass, it was observed that the hand grip strength in both genders was positively correlated with arm muscle circumference (p = 0.0196 and lean mass (p = 0.0002. Fat mass measured by the bioelectrical impedance method already showed a significant inverse relationship with the grip (r = -0.3879. The thickness of the adductor pollicis muscle showed significant association with lean mass (p = 0.0052 and hand grip (p = 0.0024. Conclusion: In this study, the hand grip strength and thickness of the adductor pollicis muscle were well correlated with measurements determined by anthropometry and bioimpedance. The results show the applicability of grip strength and thickness of the adductor pollicis muscle in clinical practice as nutritional assessment methods for this population, especially elderly patients, since they detect functional changes not captured by other parameters in the short term and are important for early identification of risk nutrition.

    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.

    2004-01-01

    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.

    Voice dysfunction or dysphonia may be associated with several clinical conditions. Among these, laryngeal human papillomavirus (HPV)-induced lesions should be considered as a possible causative factor. We report a case of dysphonia in a patient presenting with an HPV laryngeal lesion. We also discuss the clinical features of the disease, its histopathological findings, and treatment and rigorous follow-up. We report a case of laryngeal papilloma in a 29-year-old, Afro-descendant, male patient with dysphonia. He was a non-smoker and was not a drug user. Videolaryngostroboscopy revealed signs suggestive of pharyngolaryngeal reflux. The right vocal fold presented with a papillomatous aspect in the posterior third, which underwent excision. Histopathological examination showed a nodular lesion of the right vocal fold, conclusive of squamous papilloma with absence of malignancy. Patients presenting with persistent voice dysfunction or dysphonia should be investigated for possible laryngeal HPV infection. Diagnostic confirmation by HPV genotyping is important for follow-up of potential recurrence.

    2013-01-01

    A melt fluxing technique has been used to undercool Ag-Cu eutectic alloy by 10-70 K and the subsequent recalescence has been studied using high speed imaging. Spasmodic growth of the solidification front was observed, in which the growth front would make a series of quasi-periodic jumps separated by extended periods during which time growth appeared to arrest. Evidence of this previously unreported mode of growth is presented. The high speed images and microstructural evidence support the theory that anomalous eutectics form by the growth and subsequent remelting of eutectic dendrites.

  1. Spasmodic Torticollis—A Multicentre Study on Behavioural Aspects III: Psychosocial Changes and Coping

    Directory of Open Access Journals (Sweden)

    T. Nickel

    1996-01-01

    Full Text Available Psychosocial changes in spasmodic torticollis (ST affect predominantly social life, professional life and psychological well-being. Concerning social life, 84.6% of the patients felt that they attracted considerable public attention due to their neurological illness and 65% had reduced participation in social events. A substantial number of patients had retired from professional activities; others felt severely impaired in their working capacity. The psychosocial sequelae in ST, however, seemed to depend less on the neurological signs per se than on the physical symptoms and on coping. Depressive coping in particular emerged as a predictor of psychosocial distress.

    The pathophysiology of spasmodic torticollis, a focal dystonia involving neck muscles, is still unclear. Positron emission tomography (PET) studies showed either an increase as well as a decrease of regional cerebral metabolic rate of glucose (rCMRglu) in basal ganglia. In the present study, [18F]FDG and PET was used to measure rCMRglu in 10 patients with spasmodic torticollis (mean age 50.37 {plus_minus} 11.47) and 10 age matched controls. All cases with a short disease duration, were untreated. A factorial analysis of variance revealed a significant bilateral increase of glucose consumption in caudate nucleus and pallidum/putamen complex (p>0.004) and in the cerebellum (p>0.001). The rCMRglu increase in the motor/premotor cortex and in the thalamus reached a trend towards significance (p<0.05). These preliminary data show enhanced metabolism in basal ganglia and cerebellum as the functional correlate of focal dystonia. A recently proposed model suggests that dystonia would be the consequence of a putaminal hyperactivity, leading to the breakdown of the pallidal inhibitory control on thalamus and thalamo-cortical projections.

  3. Hip adductor activations during run-to-cut manoeuvres in compression shorts: implications for return to sport after groin injury.

    2014-01-01

    Athletes at high risk of groin strains in sports such as hockey and soccer often choose to wear shorts with directional compression to aid in prevention of or recovery from hip adductor strains. Large, eccentric contractions are known to result in or exacerbate strain injuries, but it is unknown if these shorts have a beneficial effect on hip adductor muscle activity. In this study, surface electromyography (EMG) of the adductor longus and ground reaction force (GRF) data were obtained simultaneously on 29 healthy individuals without previous history of serious injury while performing unanticipated 45° run-to-cut manoeuvres in a laboratory setting wearing shorts with non-directional compression (control, HeatGear, Under Armour, USA) or shorts with directional compression (directional, CoreShort PRO, Under Armour, USA), in random order. Average adductor activity in the stance leg was significantly lower in the directional condition than in the control condition during all parts of stance phase (all P < 0.042). From this preliminary analysis, wearing directional compression shorts appears to be associated with reduced stance limb hip adductor activity. Athletes seeking to reduce demand on the hip adductors as they approach full return to activities may benefit from the use of directional compression shorts.

    The block of nerves in the adductor canal is considered to cause a sensory block without a motor component. In this report, we describe a case of significant quadriceps muscle weakness after an adductor canal block (ACB). A 65-year-old female patient for ambulatory knee surgery was given an ACB for postoperative pain management. The block was performed under ultrasound guidance at the midthigh level using the transsartorial approach. Twenty milliliters of 0.5% ropivacaine was deposited adjacent to the anterior and posterior areas of the femoral artery. On discharge from the hospital, the patient realized that her thigh muscles were weak and she was unable to extend her leg at the knee. A neuromuscular examination indicated that the patient had no strength in her quadriceps muscle, along with sensory deficit in the medial-anterior lower leg and area in front of knee up to the midthigh. The weakness lasted 20 hours, and the sensory block lasted 48 hours before complete recovery. The optimal level and amount of local anesthetic for adductor canal block are currently not well defined. Proximal spread of local anesthetic and anatomical variation may explain our observation. Several studies have reported that ACB involves no motor blockade. However, our case report illustrates that the ACB can result in clinically significant quadriceps muscle paralysis. This report suggests that patients should be monitored vigilantly for this occurrence to decrease the risk of falls.

  6. An evaluation study of voice therapy in non-organic dysphonia.

    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.

    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.

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.

    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.

    Femoroacetabular impingement (FAI) is a common debilitating condition that is associated with groin pain and limitation in young and active patients. Besides FAI, various disorders such as hernias, adductor tendinopathy, athletic pubalgia, lumbar spine affections, and others can cause similar symptoms. To determine the prevalence of inguinal and/or femoral herniation and adductor insertion tendinopathy using dynamic ultrasound in a cohort of patients with radiographic evidence of FAI. Case series; Level of evidence, 4. This retrospective study consisted of 74 patients (36 female and 38 male; mean age, 29 years; 83 symptomatic hips) with groin pain and radiographic evidence of FAI. In addition to the usual diagnostic algorithm, all patients underwent a dynamic ultrasound examination for signs of groin herniation and tendinopathy of the proximal insertion of the adductors. Evidence of groin herniation was found in 34 hips (41%). There were 27 inguinal (6 female, 21 male) and 10 femoral (9 female, 1 male) hernias. In 3 cases, inguinal and femoral herniation was coexistent. Overall, 5 patients underwent subsequent hernia repair. Patients with groin herniation were significantly older than those without (33 vs 27 years, respectively; P = .01). There were no significant differences for any of the radiographic or clinical parameters. Tendinopathy of the proximal adductor insertion was detected in 19 cases (23%; 11 female, 8 male). Tendinopathy was coexistent with groin herniation in 8 of the 19 cases. There were no significant differences for any of the radiographic or clinical parameters between patients with or without tendinopathy. Patients with a negative diagnostic hip injection result were more likely to have a concomitant groin hernia than those with a positive injection result (80% vs 27%, respectively). Overall, 38 hips underwent FAI surgery with satisfactory outcomes in terms of score values and subjective improvement. The results demonstrate that groin

    Full Text Available Cervical dystonia (CD is a prevalent and incapacitating movement disorder which needs a thorough clinical evaluation of every patient to better tailor treatment strategies. In Brazil, there are no validated CD scales that measure the burden of dystonia. The aim of our study was to translate and adapt the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS to Brazilian Portuguese. After translation and back-translation according to international methods, a pre-test was carried out with 30 patients. Patients under 8 years of formal schooling had severe difficulty in understanding the whole scale. The scale went through a remodeling process, without loss of its conceptual and semantic properties. The new scale was tested in 15 patients, with good understanding scores. We are now in the process of validation of the adapted scale.

    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.

    To assess the clinical efficacy of acupuncture at key acupoints combined with the routine rehabilitation training of limb function on spasmodic hemiplegia after cerebral infarction. Eighty-six cases were randomized into an acupuncture combined with rehabilitation group (group A, 44 cases) and a rehabilitation group (group B, 42 cases). In group A, the key acupoints were selected from head, face, chest, abdomen, shoulder, back, hands, feet and ankles such as Cuanzhu (BL 2), Danzhong (CV 17), Jianyu (LI 15) and Yanglao (SI 16) were stimulated with acupuncture. In combination, the routine limb rehabilitation training was applied, once every day. In group B, the routine limb rehabilitation training was applied alone. In both groups, 10 treatments made one session and 2 sessions were required totally. Before and after treatment, Fugl-Meyer scale and functional independent measurement (FIM) scale were adopted to assess the limb motor level and the activity of daily life in the patients respectively. The modified Ashworth scale was used to assess the effect of anti-spasm. The total effective rate of anti-spasm was 90.9% (40/44) in the group A, which was superior to 73.8% (32/42) in the group B (P rehabilitation therapy effectively relieves the spasmodic condition of the patients with post-stroke spasmodic hemiplegia, improves the limb function and the life activity of the patients.

    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.

    We have examined the anatomy and fibre type composition of the human adductor pollicis in muscles taken post mortem. Histochemical staining of muscle fibres showed that type I fibres predominated in all cases with a mean occurrence of 80%. This composition is similar to that of the soleus muscle and unlike that of the quadriceps which has approximately equal proportions of the two fibre types. Comparing the contractile characteristics, however, the adductor pollicis has similar properties to the quadriceps and both are quite distinct from those of the slowly contracting soleus muscle. The lack of correlation between fibre composition, as revealed by histochemical staining, and contractile properties in these muscles must mean that fibres of the same type from different muscles do not necessarily have the same contractile speed. The results also suggest that the type I fibres of the human adductor pollicis are faster than those of both the soleus and quadriceps muscles.

    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.

  10. Elbow joint adductor moment arm as an indicator of forelimb posture in extinct quadrupedal tetrapods.

    Fujiwara, Shin-ichi; Hutchinson, John R

    2012-07-07

    Forelimb posture has been a controversial aspect of reconstructing locomotor behaviour in extinct quadrupedal tetrapods. This is partly owing to the qualitative and subjective nature of typical methods, which focus on bony articulations that are often ambiguous and unvalidated postural indicators. Here we outline a new, quantitatively based forelimb posture index that is applicable to a majority of extant tetrapods. By determining the degree of elbow joint adduction/abduction mobility in several tetrapods, the carpal flexor muscles were determined to also play a role as elbow adductors. Such adduction may play a major role during the stance phase in sprawling postures. This role is different from those of upright/sagittal and sloth-like creeping postures, which, respectively, depend more on elbow extensors and flexors. Our measurements of elbow muscle moment arms in 318 extant tetrapod skeletons (Lissamphibia, Synapsida and Reptilia: 33 major clades and 263 genera) revealed that sprawling, sagittal and creeping tetrapods, respectively, emphasize elbow adductor, extensor and flexor muscles. Furthermore, scansorial and non-scansorial taxa, respectively, emphasize flexors and extensors. Thus, forelimb postures of extinct tetrapods can be qualitatively classified based on our quantitative index. Using this method, we find that Triceratops (Ceratopsidae), Anhanguera (Pterosauria) and desmostylian mammals are categorized as upright/sagittally locomoting taxa.

    Full Text Available Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle. Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P<0.001. A statistically significant improvement in the peak torque of the quadriceps muscle and flexor was observed for 60°/sec and 180°/sec angular velocities (P=0.01. Our results confirm the efficacy of MPFL reconstruction using the adductor magnus tendon in children and adolescents with recurrent patellar dislocation.

    Full Text Available The postmortem catabolism of adenosine triphosphate (ATP in cold-stored adductor muscles from scallops (Zygochlamys patagónica was studied. Changes in the pH of stored muscles were also studied. The ATP content increased for a short time after death and afterwards decreased up to 24 hr of storage. Thereafter, the nucleotide level remained unchanged up to the end of storage. The ADP content slightly decreased up to 48 hr and after that remained unchanged. The AMP slowly accumulated to around 15% of the total nucleotide concentration when the ATP decreased. Small amounts of IMP were detected in all samples. Conversely, adenosine (Ado was not detected. Inosine (HxR increased slightly after 48 hr of storage and hypoxanthine (Hx increased significantly after 24 hr. The 260/250 absorbance ratio of muscle extracts and the pH of stored muscles fell sharply up to 24 hr and then decreased slowly up to the end of storage. The hypoxanthine concentration and the 260/250 absorbance ratio could be reliable indicators of storage age in adductor muscles from scallops.

    Neuronal activity of 50 neurons in nonspecific (Rt, MD) and relay (Voi, Voa) thalamic nuclei was analyzed. Data were obtained by microelectrode technique during 14 stereotactic operations in patients with spasmodic torticollis. Application of Poincare maps and Gap-statistics allowed to reveal 3 main patterns of neuronal activity: irregular single spikes, low-threshold Ca(2+)-dependent rhythmic (3-5 Hz) bursts and combination of bursts and single spikes. In some cases, grouping (in Voi and Rt nuclei) and long burst (in Voa nucleus) patterns were observed. Grouping pattern consist of low-density groups of spikes with tendency to periodicity in range 1-1.5 Hz. Long burst pattern consist of long dense groups of spikes with random length and invariant interburst intervals. Main numerical estimations of 3 most spread patterns of neuronal activity were obtained by parametric analysis. In results, investigated thalamic nuclei significantly distinguished from each other by characteristics of burst activity but average firing rate of these nuclei hadn't significant differences. These data may be useful for functional identification of thalamic nuclei during stereotactic neurosurgery operation in patients with movement disorders.

    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.

    Wilson disease (WD) is an autosomal-recessive disorder of hepatic copper metabolism that has tremendous variability in its presentation. Phenotypic diversity of the disease can lead to delayed diagnosis. We describe a case of WD in a 10-year-old boy presenting with 3 months of increasingly intense, spasmodic lower extremity muscle cramps. Physical examination revealed tenderness on calf palpation and dark flat lesions over his ankles, knees, and elbows. Initial testing revealed creatine kinase of 302 IU/L (normal 24-248 IU/L), hemoglobin of 8.9 g/dL (11.5-15.5 g/dL), aspartate aminotransferase of 114 IU/L (16-52 IU/L), alanine aminotransferase of 54 IU/L (2-30 IU/L), and myoglobinuria. Extensive evaluation of his myopathy, including MRI and muscle biopsy, was negative. Additional laboratory tests revealed a prothrombin time of 21.3 seconds (11.8-15.5 seconds), total bilirubin of 1.4 mg/dL (muscle weakness. In patients with unexplained musculoskeletal symptoms and hepatic abnormalities, a diagnosis of WD should be considered and appropriate evaluation initiated.

    2011-01-01

    This work aims to create a scale to evaluate posture, quick and easy to perform during the assessment of voice in patients with simple dysfunctional dysphonia. The "S-TRAV" scale was evaluated on 60 subjects with dysphonia and 60 control subjects. It assesses "the overall severity" of the alteration of posture, the "Tension", the "Breathing", the "Ground anchoring" and the "Verticality" both quantitatively (score 0-3) and qualitatively. The patient also assesses his voice disorder and his posture. Postural observation was carried out in five conditions: at rest, conversational voice, reading, projected voice and singing voice. The comparison between the dysphonic subjects and control subjects was used to assess the sensitivity of this tool. Two reviewers rated the scale to determine its reproducibility. The scale is sensible for the majority of criteria with a significance coefficient less than 0.05. The most discriminate criteria relate to the cervical spine, the overall score of postural severity assessed by the therapist and verticality. All criteria have a low level of variability between the reviewers under all conditions. Most criteria are correlated with the criterion "Overall Severity" of postural alterations under all conditions. Non-sensible criteria were eliminated from the final scale). This tool is sensitive, reproducible and relevant in assessing the severity of postural alterations and their location. Further studies will validate the scale on a consistent population.

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

    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.

    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.

    Myasthenia gravis is an autoimmune disease, manifested by progressive muscular weakness and fatigue. There are frequent ocular and bulbar symptoms, among them, dysphonia. This article reports a case of dysphonia that contributed to the diagnosis of myasthenia gravis through a speech evaluation. The patient sought speech therapy with the ENT diagnosis of presbyphonia. The perceptual voice assessment and acoustic analysis pointed out respiration, glottal voice source and resonance affections. Considering that some of the data obtained from anamnesis and vocal assessments were not directly related to presbyphonia, the speech therapist discussed the case with the physician and they both concluded it was necessary to refer the patient to a neurological evaluation. The neurologist then raised the diagnostic hypotheses of myasthenia gravis and requested further examinations. The patient underwent speech therapy and drug treatment. A vocal reassessment, which occurred two months after the initial treatment, showed improvement in voice quality, with great impact on quality of life. This article shows the importance of detailed clinical speech evaluation and participation of a speech therapist in an interdisciplinary team.

  3. 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

    Based on our previous finding that the concentrations of total mercury in mussel adductor muscle approximated those of methylmercury, we compared concentrations of total mercury in the adductor muscle of the mussel Mytilus galloprovincialis, collected from four sites around Minamata City from 1993 to 1995 and four sites in Kagoshima Bay from 1997 to 1998, to assess the level of localized methylmercury contamination. Though the input of mercury from the chemical plant had stopped by around 1970, concentrations of total mercury in the mussel adductor muscle were higher at two sites (26-121 ng/g, n = 135) near the main fallout of wastewater from the chemical plant in Minamata Bay than at the other sites, i.e. two sites 1-5 km from the former sites in Minamata City (6-28 ng/g, n = 52), and all sites in Kagoshima Bay (2-30 ng/g, n = 287). The localized methylmercury contamination around the chemical plant in Minamata Bay was documented also by our sensitive analysis of mercury concentrations in seawater and sediment samples. The survey of concentrations of total mercury in the mussel adductor muscle seems to be useful for monitoring the methylmercury contamination in coastal areas.

  8. Complete avulsion of the adductor longus in a semi-professional football player: Rapid return to play with nonoperative treatment

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The adductor longus has become recognized as one of the more commonly injured muscles in the medial compartment. Acute complete rupture injuries occurring at the proximal aspect of the muscle are less common. Limited data exist regarding management of the injuries in athletes required for return to play and functioning. The current data favors operative management; however, nonoperative treatment may be a viable option. Nonoperative management of avulsion injuries of the proximal adductor longus tendon may prove equal results to surgical repair in return to play and functioning. A semi-professional football player sustained a left groin injury while participating in the play. Due to continued pain, swelling, and suspicion of injury, a magnetic resonance imaging was performed diagnosing a complete tear of proximal adductor longus tendon. Physical examination, strength, and range of motion were recorded until the patient was able to function normally without strength deficit, the range of motion loss, and the return of speed. The player was treated nonoperatively and was eventually allowed to return to play. The time of return to play was 6 weeks. Strength deficit was not appreciated or loss of motion and player was able to return to baseline function. Nonoperative management of complete avulsion injuries of the proximal adductor longus tendon result in faster return to play than operative management even if significant retraction is present.

  9. Contractile properties of the striated adductor muscle in the bay scallop Argopecten irradians at several temperatures.

    Olson, J M; Marsh, R L

    1993-03-01

    The isometric and isotonic contractile properties of the cross-striated adductor muscle of the bay scallop (Argopecten irradians) were measured in vitro at 10, 15 and 20 degrees C. The length at which twitch force was maximal as a function of the closed length in situ (L0/Lcl) averaged 1.38 +/- 0.01 (mean +/- S.E.M.) at 10 degrees C. This length is very close to the typical length at maximum gape during natural swimming at this temperature. Passive force was very low over the range of lengths measured here; at L0, passive force averaged approximately 0.08 N cm-2, or only 0.5% of the corresponding peak twitch force. The mean peak isometric twitch force (Ptw,max) at 10 degrees C was 21.43 +/- 0.68 N cm-2 (S.E.M.), and the ratio of peak twitch force to tetanic force (Ptw,max/P0) averaged 0.89 +/- 0.01. Temperature did not affect either twitch force (Ptw), once fatigue was taken into account, or Ptw,max/P0. In contrast, the time-related properties of twitch contractions (latent period, tL; time to peak tension, tPtw; and time from peak tension to half-relaxation, t50%R) were positively modified by temperature at all temperatures measured (Q10 > 1.8). All three properties were more temperature-sensitive over the range 10-15 degrees C than over the range 15-20 degrees C. The force-velocity relationships of the striated adductor muscle were fitted to the hyperbolic-linear (HYP-LIN) equation. The force-velocity curves of the striated adductor muscle of the scallop were strongly influenced by temperature. Maximal velocity at zero force (Vmax), and therefore maximal power output, increased significantly with temperature. The Q10 over the temperature range 10-15 degrees C (1.42) was significantly lower than that over the range 15-20 degrees C (2.41). The shape of the force-velocity relationship, assessed through comparisons of the power ratio (Wmax/VmaxP0), was not influenced by temperature.

  10. A Preliminary Study on the Pattern, the Physiological Bases and the Molecular Mechanism of the Adductor Muscle Scar Pigmentation in Pacific Oyster Crassostrea gigas

    Full Text Available The melanin pigmentation of the adductor muscle scar and the outer surface of the shell are among attractive features and their pigmentation patterns and mechanism still remains unknown in the Pacific oyster Crassostrea gigas. To study these pigmentation patterns, the colors of the adductor muscle scar vs. the outer surface of the shell on the same side were compared. No relevance was found between the colors of the adductor muscle scars and the corresponding outer surface of the shells, suggesting that their pigmentation processes were independent. Interestingly, a relationship between the color of the adductor muscle scars and the dried soft-body weight of Pacific oysters was found, which could be explained by the high hydroxyl free radical scavenging capacity of the muscle attached to the black adductor muscle scar. After the transcriptomes of pigmented and unpigmented adductor muscles and mantles were studied by RNAseq and compared, it was found that the retinol metabolism pathway were likely to be involved in melanin deposition on the adductor muscle scar and the outer surface of the shell, and that the different members of the tyrosinase or Cytochrome P450 gene families could play a role in the independent pigmentation of different organs.

    Full Text Available Objective: The hip dislocation especially in spastic form of cerebral palsy frequently occurs. It results in significant morbidity in terms of pain in the dislocated hip and destabilization of the pelvis. The aim of this study was to evaluate the migration percentage in patients where only tenotomies of the adductor muscles were performed compared to patients where tenotomies of the adductor muscles were combined with neurectomy of the obturator nerve. Methods: We retrospectively evaluated 50 patients (80 hips divided in two groups. In 32 patients (47 hips tenotomies of the adductor muscles were performed, in 18 patients (33 hips tenotomies of the adductormuscles were combined with neurectomy of the obturator nerve in order to prevent and to decrease the incidence of hip dislocation. We used the Reimers’ hip migration percentage to evaluate the stability of the articulation. Results: In the group where tenotomies of the adductor muscles were combined with neurectomy of the obturator nerve, we cannot find a statistically significant difference when compared to the group where only tenotomies of the adductor muscles were performed. In the two year follow up period after the operations, a decrease of the migration percentage was noted in both groups of patients with gradual increase in the following period. Conclusion: There was no significant difference in the end result when performing tenotomies of the adductor muscles combined with neurectomy of the obturator nerve compared with tenotomies of the adductor muscles only

    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.

    Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle). Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P magnus tendon in children and adolescents with recurrent patellar dislocation.

  16. Force depression following muscle shortening in sub-maximal voluntary contractions of human adductor pollicis.

    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

    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.

    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.

    This investigation explored the potential usefulness of topical lidocaine in the treatment of muscle tension dysphonia. Three patients with this disorder, who were previously unresponsive to standard voice therapy, were treated with lidocaine. In each case, the outcome was prompt, clinically significant, and sustained. Persistently high-pitched and shrill vocal quality was converted to near normal voice patterns within 15 minutes after transcricothyroid membrane lidocaine injection. We suggest that this temporary and simple laryngeal and tracheal anesthetic technique may have helped to break the perverse cycle of hyperactive glottal and supraglottal muscle contractions evident in each of these patients during phonation efforts. We discuss the possible sensorimotor mechanism of action of this therapeutic technique.

    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.

    Aim of this review is to summarize the studies carried out, with particular interest in those who dealt with otilonium bromide in treatment of IBS. Irritable bowel syndrome (IBS). IBS is a frequent gastrointestinal disease, characterized by a combination of several symptoms including abdominal pain or discomfort, flatulence and problems related to bowel habits (constipation and/or diarrhea). It affects about 15% of the western population, with a negative impact on the quality of life and also on health care costs. Face to such important complexity and negative impact, therapeutic options are still very limited and most of the pharmacological compounds mostly validated for short term use, are only partially controlling symptoms. Among those, anti-spasmodics are commonly used in clinical settings. Despite a discrete literature in support of these drugs, systematic collections of clinical evidence to support the use of anti-spasmodics and in particular the use of otilonium bromide in course of IBS are scarce. Otilonium bromide is a systemically poorly absorbed antispasmodic, which has shown clear efficacy compared to placebo, in controlling symptoms related to IBS. Otilonium bromide was effective also in comparison to other drugs, such as pinaverium bromide and mebeverine, with a favorable tolerability profile. Further studies are necessary to better define duration of treatment and maximum therapeutic dose.

    To study the effectiveness of ansa-recurrent laryngeal nerve laryngeal reinnervation to improve glottal incompetence causing dysphonia and dysphagia for children with unilateral vocal fold paralysis. DESIGN We reviewed a series of consecutive cases treated from January 1, 2006, through December 31, 2011. Otolaryngology division of a children's hospital. PATIENTS Thirteen children with unilateral vocal fold paralysis. Surgical complications, parent surrogate quality-of-life measures, global overall assessment of improvement, and auditory perceptual assessment. Thirteen children underwent laryngeal reinnervation. Ages ranged from 2.2 to 8.8 years (mean [SD] age, 5.3 [2.6] years). No major complications were identified. Nine children had preoperative and 6- to 12-month postoperative data on voice and swallowing. Mean parental global voice rating (0 indicates no voice; 100%, normal voice) changed from 43% (range, 20%-65%) preoperatively to 79% (range, 50%-100%) postoperatively. Regarding perceptual assessment, the mean GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) Rating Scale sum score (0 indicates normal voice; 15, profoundly abnormal voice) improved from 6.3 to 2.9. Parental assessment of dysphagia with liquids also improved for all children with preoperative symptoms and worsened for none. Our early experience suggests that ansa-recurrent laryngeal nerve laryngeal reinnervation is a safe and effective treatment for unilateral vocal fold paralysis with symptomatic dysphonia and dysphagia in young children. The procedure has advantages compared with other treatments. This option should be discussed with parents when the paralysis is identified. The child should be observed for several years in the event that voice and swallowing symptoms from glottal incompetence do not improve.

    Full Text Available Background: Special consideration has recently been given to cepstral analysis with mel-frequency cepstral coefficients (MFCCs. The aim of this study was to assess the applicability of MFCCs in acoustic analysis for diagnosing occupational dysphonia in comparison to subjective and objective parameters of voice evaluation. Materials and Methods: The study comprised 2 groups, one of 55 female teachers (mean age: 45 years with occupational dysphonia confirmed by videostroboscopy and 40 female controls with normal voice (mean age: 43 years. The acoustic samples involving sustained vowels "a" and four standardized sentences were analyzed by computed analysis of MFCCs. The results were compared to acoustic parameters of jitter and shimmer groups, noise to harmonic ratio, Yanagihara index evaluating the grade of hoarseness, the aerodynamic parameter: maximum phonation time and also subjective parameters: GRBAS perceptual scale and Voice Handicap Index (VHI. Results: The compared results revealed differences between the study and control groups, significant for MFCC2, MFCC3, MFCC5, MFCC6, MFCC8, MFCC10, particularly for MFCC6 (p < 0.001 and MFCC8 (p < 0.009, which may suggest their clinical applicability. In the study group, MFCC4, MFCC8 and MFCC10 correlated significantly with the major objective parameters of voice assessment. Moreover, MFCC8 coefficient, which in the female teachers correlated with all eight objective parameters, also showed the significant relation with perceptual voice feature A (asthenity of subjective scale GRBAS, characteristic of weak tired voice. Conclusions: The cepstral analysis with mel frequency cepstral coefficients is a promising tool for evaluating occupational voice disorders, capable of reflecting the perceptual voice features better than other methods of acoustic analysis.

    The scallop adductor muscle consists of striated fibres responsible for the fast closure of the shells, and smooth fibres able to maintain tension in a prolonged state of contraction called catch. Formation of the force-bearing catch linkages has been demonstrated to be initiated by dephosphorylation of the key catch-regulating factor twitchin by a calcineurin-like phosphatase, while the involvement of other thick filament proteins is uncertain. Here we report on the development of catchability of the adductor smooth muscle in the great scallop (Pecten maximus) by analysing the spatio-temporal gene expression patterns of the myosin regulatory light chain (MLCr), twitchin, myorod and calcineurin using whole mount in situ hybridization and real-time quantitative PCR. The MLCr signal was identified in the retractor and adductor muscles of the pediveliger larvae, and the juvenile and adult scallop displayed abundant mRNA levels of MLCr in the smooth and striated adductor muscles. Twitchin was mainly expressed in the smooth adductor muscle during metamorphosis, whereas the adult striated adductor muscle contained seven-folds higher twitchin mRNA levels compared to the smooth portion. Calcineurin expression predominated in the gonads and in the smooth adductor, and five-folds higher mRNA levels were measured in the smooth than in the striated fibres at the adult stage. In contrast to the other genes examined, the expression of myorod was confined to the smooth adductor muscle suggesting that myorod plays a permissive role in the molluscan catch muscles, which are first required at the vulnerable settlement stage as a component of the predator defence system.

    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. This study also suggests using

    This is the first study to evaluate the mechanical sensitivity, clinical classifications and prevalence of groin pain in Australian football players. Case-control. Professional (n=66) and semi-professional (n=9) Australian football players with and without current or previous groin injuries were recruited. Diagnoses were mapped to the Doha Agreement taxonomy. Point and career prevalence of groin pain was calculated. Pressure pain thresholds (PPTs) were assessed at regional and distant sites using handheld pressure algometry across four sites bilaterally (adductor longus tendon, pubic bone, rectus femoris, tibialis anterior muscle). To assess the relationship between current groin pain and fixed effects of hyperalgesia of each site and a history of groin pain, a mixed-effect logistic regression model was utilised. Receiver Operator Characteristic (ROC) curve were determined for the model. Point prevalence of groin pain in the preseason was 21.9% with a career prevalence of 44.8%. Adductor-related groin pain was the most prevalent classification in the pre-season period. Hyperalgesia was observed in the adductor longus tendon site in athletes with current groin pain (OR=16.27, 95% CI 1.86 to 142.02). The ROC area under the curve of the regression model was fair (AUC=0.76, 95% CI 0.54 to 0.83). Prevalence data indicates that groin pain is a larger issue than published incidence rates imply. Adductor-related groin pain is the most common diagnosis in pre-season in this population. This study has shown that hyperalgesia exists in Australian football players experiencing groin pain indicating the value of assessing mechanical pain sensitivity as a component of the clinical assessment.

    Patellar dislocations are associated with injuries to the medial patellofemoral ligament (MPFL). Several techniques for MPFL reconstruction have been recently published with some disadvantages involved, including large skin incisions and donor site morbidity. Arthroscopic stabilizing techniques carry the potential of inadequate restoration of MPFL function. We present a minimally invasive technique for MPFL reconstruction using adductor magnus tendon autograft. This technique is easily performed, safe, and provides a stabilizing effect equal to current MPFL reconstructions. Skin incision of only 3-4 cm is located at the level of the proximal half of the patella. After identifying the distal insertion of the adductor magnus tendon, a tendon harvester is introduced to harvest the medial two-thirds of the tendon, while the distal insertion is left intact. The adductor magnus tendon is cut at 12-14 cm from its distal insertion and transferred into the patellar medial margin. Two suture anchors are inserted through the same incision at the superomedial aspect of the patella in the anatomic MPFL origin. The graft is tightened at 30 degrees knee flexion. Aftercare includes 4 weeks of brace treatment with restricted range of motion.

    2003-09-01

    Sex differences in fatigue resistance of the adductor pollicis (AP) muscle were studied in 24 older adults who were divided into three groups: 12 older men (69.8 +/- 4.60 years), 6 older women not on hormone replacement therapy (HRT) (70.2 +/- 4.02 years), and 6 older women on HRT (68.7 +/- 6.47 years). Fatigue in the AP muscle was induced using an intermittent (5 s contraction, 5 s rest) submaximal voluntary contraction (50% of maximal voluntary contraction (MVC)) protocol, which was continued until exhaustion (i.e., when subjects could either no longer maintain a 5-s contraction at 50% MVC or when the MVC was deemed to be lower than the target force). There was no effect of HRT on MVC or time to fatigue (TTF); therefore, the older women were pooled as one subject group. At baseline, men were stronger than women for MVC (75.9 +/- 18.8 N in men vs. 56.8 +/- 10.0 N in women; P 0.20), nor was there a significant relationship between baseline muscle force and TTF (r = 0.14). There was also no difference in the pattern of fatigue and recovery between the men and women. These results suggest that there is no difference in endurance or fatigue characteristics of the AP muscle in men and women over the age of 65 years, and that baseline muscle force does not predict fatigue resistance in this muscle.

  12. Towards microprocessor-based control of droplet parameters for endoscopic laryngeal adductor reflex triggering

    Directory of Open Access Journals (Sweden)

    Fast Jacob Friedemann

    2017-09-01

    Full Text Available The so-called Laryngeal Adductor Reflex (LAR protects the respiratory tract from particle intrusion by quickly approximating the vocal folds to close the free glottal space. An impaired LAR may be associated with an increased risk of aspiration and other adverse conditions. To evaluate the integrity of the LAR, we recently developed an endoscopic prototype for LAR triggering by shooting accelerated droplets onto a predefined laryngeal target region. We now modified the existing droplet-dispensing system to adapt the fluid system pressure as well as the valve opening time to user-chosen values autonomously. This has been accomplished using a microcontroller board connected to a pressure sensor and a mechatronic syringe pump. For performance validation, we designed a measurement setup capable of tracking the droplet along a vertical trajectory. In addition to the experimental setup, the influence of parameters such as system pressure and valve opening time on the micro-droplet formation is presented. Further development will enable the physician to adjust the droplet momentum by setting a single input value on the microcontroller-based setup, thus further increasing usability of the diagnostic device.

    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.

    2015-01-01

    The purpose of this study was to use spectral and cepstral analyses of speech to investigate whether underlying physiological changes in voice result in changes in acoustic estimates of dysphonia severity in continuous speech contexts within a single breath group. The effect of dysphonia on acoustic estimates of dysphonia severity, frequency, relative intensity, and vocalization time across initial and terminal segments of a single breath group using a common clinical stimulus was investigated. Prospective quasi-experimental controlled design. Digitized recordings of the Consensus Auditory-Perceptual Evaluation of Voice sentence "We were away a year ago" were obtained from 20 treatment-seeking dysphonic individuals (females, mean age = 39 years) and 20 normal controls (females, mean age = 39 years). Each recorded sample was separated into the first four syllables ("We were away … ") and second four syllables ("…a year ago.") of the breath group. Cepstral and spectral measures, intensity measures, and temporal analyses were obtained and used in calculations of the Cepstral Spectral Index of Dysphonia (CSID, an acoustic estimate of dysphonia severity), fundamental frequency (F0), vocalization time, and relative vocal intensity (dB SLP). Statistical analyses were applied to calculations of change (delta [Δ]) in these measures from one breath group segment to the next. Results revealed a significant effect of group on measures of CSID and F0, but not relative intensity or vocalization time. Dysphonic speakers exhibited a significant increase in the CSID from the first to second breath group segment and limited variation in F0 compared with controls. These results may support the hypothesis that voice impairment increases in severity toward the termination of a breath group even within a short temporal frame (i.e., 2 seconds or less of connected speech), and that this portion of the breath group may be an important determinant of perceptual impressions.

    Volcanic tremors are seismic indicators providing clues for magma behavior, which is related to volcanic eruptions and activity. Detection of spatial and temporal variations of volcanic tremors is important for understanding the mechanism of volcanic eruptions. However, temporal variations of tremor activity in short-term than a minute have not been previously detected by seismological observations around volcanoes. Here, we show that volcanic tremor sources were activated at the top of the conduit (i.e. the crater) and at its lower end by analyzing seismograms from a dense seismic array during the 2011 Kirishima eruption. We observed spasmodic switching in the seismic ray direction during a volcanic tremor sequence. Such fine volcanic tremor structure suggests an interaction between tremor sources located in both deep and shallow depths. Our result suggests that seismic array observations can monitor the magma behavior and contribute to the evaluation of the activity's transition.

    The main objective of this study is to check the correlation between vocal self-assessment and results of the Voice-Related Quality of Life (V-RQOL) protocol, and whether there is a correlation between perceptual vocal assessment made by voice therapists and the results from the V-RQOL protocol. The study included 245 subjects with vocal complaints. This was a prospective analytical clinical study. Vocal perceptual assessment of each subject with dysphonia was made by three voice therapists, followed by self-assessment made by the subjects themselves, and the application of the V-RQOL protocol. The results have shown poor level of agreement between vocal assessment made by the voice therapists and self-assessment made by the subjects. The statistical analysis indicated that the results of V-RQOL protocol showed significant correlation with the vocal assessment made by the voice therapists and the self-assessment by the subjects. The agreement between the assessments was low and variable; age, gender, professional voice use, and clinical laryngoscopic diagnosis did not influence the agreement level. Protocol V-RQOL is sensitive to vocal assessment made by the voice therapists and self-assessment made by the patient. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    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.

    This study aimed to evaluate the validity and reliability of a Hebrew translation of the Pediatric Voice Handicap Index (pVHI). It also examined differences between mothers and fathers in evaluating their child's dysphonia. Observational design. The pVHI was first translated and adapted to Hebrew. The translated version was, then, administered to a group of 141 parents of children aged younger than 14 years. Fifty-eight parents had a dysphonic child, and 83 had a nondysphonic child. Based on the parents' responses to the pVHI, statistical analyses were performed, evaluating validity and reliability, as well as group differences. Following, a subset of the participants, in which only cases where the responses of both parents were available, was examined for evaluating differences between the responses of mothers (n = 46) and fathers (n = 46). Statistical analyses revealed high reliability of the Hebrew version of the pVHI (Cronbach alpha = .97). Parents of the dysphonic children rated their children significantly higher than parents of the nondysphonic group (P  0.05). The Hebrew version of the pVHI is a reliable tool for quantifying parents' perception of their child's voice handicap. Mothers of dysphonic children evaluate their children's voice handicap more severely than fathers, whereas both parents of nondysphonic children perform this evaluation similarly.

    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.)

    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.

    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.

    Full Text Available This study aims to investigate the relationship between current smoking and lifetime amount smoked and the incidence of dysphonia using data from a national cross-sectional survey that represents the Korean population. Subjects were 3,600 non-institutionalised civilian adults over the age of 19 (1,501 males and 2,099 females who completed the laryngeal examination of the 2008 Korea National Health and Nutrition Examination Survey (KNHANES. For lifetime amount smoked, subjects were classified as light smokers (≤26.7 pack years, medium smokers (26.7–40.5 pack years, heavy smokers (40.5–55.5 pack years, and very heavy smokers (55.5–156 pack years based on pack years (packs smoked per day × years as a smoker. The odds ratio (OR for the statistical test was presented using hierarchical logistic regression. When adjusted for covariates (age, gender, level of education, income, occupation, alcohol consumption and pain/discomfort during the last two weeks, current smokers had a 1.8 times (OR = 1.77, 95% CI [1.17–2.68] higher risk for self-reported voice problems than non-smokers. Moreover, current smokers had a 1.6 times (OR = 1.56, 95% CI [1.02–2.38] higher risk of laryngeal disorder (p < 0.05. In terms of pack years, very heavy smokers were significantly more likely to have laryngeal disorder, while self-reported voice problems were significantly more likely for heavy smokers but not very heavy smokers. The results of this study imply that chronic smoking has a significant relationship with dysphonia. Longitudinal studies are required in future work to verify the causality between lifetime smoking amount and dysphonia.

    Objective This study investigated the role of a specialized physical therapy program for muscle tension dysphonia patients as an adjunct to standard of care voice therapy. Study Design Retrospective Cohort Study Methods Adult MTD patients seen between 2007 and 2012 were identified from the clinical database. They were prescribed voice therapy and, if concomitant neck pain, adjunctive physical therapy. In a pragmatic observational cohort design, patients underwent one of four potential treatment approaches: voice therapy alone (VT), voice therapy and physical therapy (VT+PT), physical therapy alone (PT), or incomplete/no treatment. Voice handicap outcomes were compared between treatment approaches. Results Of 153 patients meeting criteria (Median age 48 years, 68% female, and 30% had fibromyalgia, chronic pain, chronic fatigue, depression, and/or anxiety), there was a similar distribution of patients with moderate or severe pre-treatment VHI scores across treatment groups (VT 45.5%, VT+PT 43.8%, PT 50%, no treatment 59.1%; p=0.45). Patients treated with VT alone had significantly greater median improvement in VHI than those not treated: 10-point vs. 2-point (p=0.02). Interestingly, median VHI improvement in patients with baseline moderate-severe VHI scores was no different between VT (10), VT+PT (8) and PT alone (10; p=0.99). Conclusions Findings show voice therapy to be an effective approach to treating MTD. Importantly, other treatment modalities incorporating physical therapy had a similar, albeit not significant, improvement in VHI. This preliminary study suggests that physical therapy techniques may have a role in the treatment of a subset of MTD patients. Larger, comparative studies are needed to better characterize the role of physical therapy in this population. PMID:26012419

    Speech range profile (SRP) is a graphical display of frequency-intensity occurring interactions during functional speech activity. Few studies have suggested the potential clinical applications of SRP. However, these studies are limited to qualitative case comparisons and vocally healthy participants. The present study aimed to examine the effects of voice disorders on speaking and maximum voice ranges in a group of vocally untrained women. It also aimed to examine whether voice limit measures derived from SRP were as sensitive as those derived from voice range profile (VRP) in distinguishing dysphonic from healthy voices. Ninety dysphonic women with laryngeal pathologies and 35 women with normal voices, who served as controls, participated in this study. Each subject recorded a VRP for her physiological vocal limits. In addition, each subject read aloud the "North Wind and the Sun" passage to record SRP. All the recordings were captured and analyzed by Soundswell's computerized real-time phonetogram Phog 1.0 (Hitech Development AB, Täby, Sweden). The SRPs and the VRPs were compared between the two groups of subjects. Univariate analysis results demonstrated that individual SRP measures were less sensitive than the corresponding VRP measures in discriminating dysphonic from normal voices. However, stepwise logistic regression analyses revealed that the combination of only two SRP measures was almost as effective as a combination of three VRP measures in predicting the presence of dysphonia (overall prediction accuracy: 93.6% for SRP vs 96.0% for VRP). These results suggest that in a busy clinic where quick voice screening results are desirable, SRP can be an acceptable alternate procedure to VRP.

    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 post-exercise flexibility were found between PNF and Static groups (p = 0.235). It is concluded that static and PNF stretching methods provoked similar post-exercise acute effects on the maximal range of motion of hip adductors in highly flexible female ballet dancers.

    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.

Material and Methods: The examinations were performed in a study (dysphonic group of professional voice users who had developed voice disorders (N = 51 and in the control group of normophonic subjects (N = 50. All the participants underwent perceptual voice assessment and examination by means of the LMTPE scale. Additionally, phoniatric examination including VHI (Voice Handicap Index questionnaire, GRBAS (the Grade of hoarseness, Roughness, Breathiness, Asthenic, Strained perceptual evaluation, maximum phonation time (MPT measurement and videostroboscopy was performed in the study group. Results: The comparison of the LMTPE total score showed that the results of the study group were significantly poorer than those of controls (p < 0.001. In the study group, correlations were found between the LMTPE results and the VHI scores (p < 0.05, perceptual evaluation by the GRBAS (p < 0.05 and the objective parameter MPT (p < 0.05. Conclusions: The study has proven that the LMTPE scale is characterized by the high score of Cronbach’s α ratio estimating the reliability of the test. The results have confirmed that the LMTPE scale seems to be a valuable tool, useful in diagnostics of occupational dysphonia, particularly of hyperfunction origin. Med Pr 2017;68(2:179–188

    A working hypothesis is described which made it possible to take into consideration the wave processes occurring in the drilling tool, and the discrete nature of crushing of rocks in limits of a single impact. A mathematical model is given for the process of impact interaction of the drilling tool with the rock. It is indicated that the nonlinear elastic link with assigned rigid characteristics under conditions of single-frequency harmonic effect result in excitation of the highest odd harmonics. It follows from this that the contact region which is a nonlinear fluctuating contour in the same way as the wave reflector can create with definite conditions polyresonance modes of oscillations of the working end of the drilling tool, and promote intensification of the processes of spasmodic crushing of rocks in systems of direct impact or impact through the drilling machine. Practical realization of the optimal nonlinear elastic bond in the region of contact of crushing tool with the rock is possible by optimizing form, dimensions and elastic properties of the crushing tool.

    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

    In this paper, we consider the use of Modulation Spectra for voice pathology detection and classification. To reduce the high-dimensionality space generated by Modulation spectra we suggest the use of Higher Order Singular Value Decomposition (SVD) and we propose a feature selection algorithm based on the Mutual Information between subjective voice quality and computed features. Using SVM with a radial basis function (RBF) kernel as classifier, we conducted experiments on a database of sustained vowel recordings from healthy and pathological voices. For voice pathology detection, the suggested approach achieved a detection rate of 94.1% and an Area Under the Curve (AUC) score of 97.8%. For voice pathology classification, an average detection rate and AUC of 88.6% and 94.8%, respectively, was achieved in classifying polyp against keratosis leukoplakia, adductor spasmodic dysphonia and vocal nodules.

    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

    BACKGROUND Acute compartment syndrome (ACS) of the thigh after elective primary total knee arthroplasty is rare. If not recognized and treated promptly, devastating consequences may result. Certain regional anesthesia techniques are thought to mask the symptoms of acute compartment syndrome, but there are no cases reported of adductor canal catheters masking the symptoms of thigh compartment syndrome. We report a case where symptoms and diagnosis of acute anterior thigh compartment syndrome were not masked by a functioning adductor canal catheter. CASE REPORT A 56-year-old male developed anterior thigh compartment syndrome after an elective primary total knee arthroplasty. Surgery was performed under spinal anesthesia with periarticular local infiltration analgesia. Postoperatively, an adductor canal catheter was placed, atraumatically, under ultrasound guidance in the recovery room with a plan to begin a continuous infusion of 0.2% ropivacaine 10 hours after the periarticular injection. Six hours after surgery, the patient complained of tightness and 10/10 pain in his right thigh, which was initially managed with parenteral opioids with moderate success. Continuous infusion through the adductor canal catheter was started and pain improved to 6/10 aching pain. Nonetheless, two hours after starting the continuous infusion, the patient reported tightness, swelling, and 10/10 pressure-like pain that was not relieved by the peripheral catheter infusion or PRN boluses of additional opioids. Due to the patient's symptomatology compartment pressures were measured. The anterior compartment pressure was 47 mm Hg and emergent anterior compartment fasciotomy was performed. CONCLUSIONS In this case, a functioning adductor canal catheter did not mask symptoms of, or delay diagnosis of, acute compartment syndrome in the thigh.

    BACKGROUND: Single-injection adductor canal block (ACB) provides analgesia after knee surgery. Which nerves that are blocked by an ACB and what influence-if any-local anesthetic volume has on the effects remain undetermined. We hypothesized that effects on the nerve to the vastus medialis muscle...... (which besides being a motor nerve innervates portions of the knee) are volume-dependent. METHODS: In this assessor- and subject-blinded randomized trial, 20 volunteers were included. On 3 separate days, subjects received an ACB with different volumes (10, 20, and 30 mL) of lidocaine 1%. In addition......L was used (P = 0.0001). No statistically significant differences were found between volume and effect on the vastus lateralis (P = 0.81) or in muscle strength (P = 0.15). CONCLUSIONS: For ACB, there is a positive correlation between local anesthetic volume and effect on the vastus medialis muscle. Despite...

    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.

    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.

    Neuromuscular monitoring using the corrugator supercilii muscle is associated with a number of challenges. The aim of this study was to assess reversal of a rocuronium-induced neuromuscular blockade with sugammadex according to monitoring either using the corrugator supercilii muscle or the adductor pollicis muscle. We hypothesized that a larger dose of sugammadex would be required to obtain a train-of-four (TOF) ratio of 1.0 with the corrugator supercilii muscle than with the adductor pollicis muscle. Forty patients aged 20-60 years and 40 patients aged ≥ 70 years were enrolled. After induction of anesthesia, we recorded the corrugator supercilii muscle response to facial nerve stimulation and the adductor pollicis muscle response to ulnar nerve stimulation using acceleromyography. All patients received 1 mg/kg rocuronium. When the first twitch (T1) of TOF recovered to 10% of control values at the corrugator supercilii, rocuronium infusion was commenced to maintain a T1 of 10% of the control at the corrugator supercilii. Immediately after discontinuation of rocuronium infusion, 2 mg/kg or 4 mg/kg of sugammadex was administered. The time for recovery to a TOF ratio of 1.0 and the number of patients not reaching a TOF ratio of 1.0 by 5 min at each dose and muscle was recorded. When neuromuscular block at the corrugator supercilii was maintained at a T1 of 10% of control, that at the adductor pollicis was deep (post-tetanic count ≤ 5). Sugammadex 4 mg/kg completely antagonized neuromuscular block at both muscles within 5 min. The time to a TOF ratio of 1.0 at the adductor pollicis was significantly longer in the group ≥ 70 years than the group 20-60 years (mean (SD): 178 (42.8) s vs. 120 (9.4) s, P sugammadex reversed neuromuscular blockade at the corrugator supercilii but not at the adductor pollicis, with 10 patients in the group 20-60 years and 8 patients in the group ≥ 70 years requiring an additional sugammadex (P

    This paper addresses voice disorder assessment. It proposes an original back-and-forth methodology involving an automatic classification system as well as knowledge of the human experts (machine learning experts, phoneticians, and pathologists). The goal of this methodology is to bring a better understanding of acoustic phenomena related to dysphonia. The automatic system was validated on a dysphonic corpus (80 female voices), rated according to the GRBAS perceptual scale by an expert jury. Firstly, focused on the frequency domain, the classification system showed the interest of 0-3000 Hz frequency band for the classification task based on the GRBAS scale. Later, an automatic phonemic analysis underlined the significance of consonants and more surprisingly of unvoiced consonants for the same classification task. Submitted to the human experts, these observations led to a manual analysis of unvoiced plosives, which highlighted a lengthening of VOT according to the dysphonia severity validated by a preliminary statistical analysis.

    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.

    Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA). Adductor canal block (ACB) is a relatively new alternative providing pure sensory blockade with minimal effect on quadriceps strength. The meta-analysis was designed to evaluate whether ACB exhibited better outcomes with respect to quadriceps strength, pain control, ambulation ability, and complications. PubMed, Embase, Web of Science, Wan Fang, China National Knowledge Internet (CNKI) and the Cochrane Database were searched for RCTs comparing ACB with FNB after TKAs. Of 309 citations identified by our search strategy, 12 RCTs met the inclusion criteria. Compared to FNB, quadriceps maximum voluntary isometric contraction (MVIC) was significantly higher for ACB, which was consistent with the results regarding quadriceps strength assessed with manual muscle strength scale. Moreover, ACB had significantly higher risk of falling versus FNB. At any follow-up time, ACB was not inferior to FNB regarding pain control or opioid consumption, and showed better range of motion in comparison with FNB. ACB is superior to the FNB regarding sparing of quadriceps strength and faster knee function recovery. It provides pain relief and opioid consumption comparable to FNB and is associated with decreased risk of falls. PMID:28079176

    Full Text Available 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

    Muscle force potentiation affects force output during electrical stimulation. Few studies have examined stimulation train parameters that influence potentiation such as pulse number, stimulation frequency, train duration, and force-time integral and peak force produced during the train. Pulse-matched trains (100 pulses) at 7.5, 15, 25, 30, 50, and 100 Hz, and trains of varying pulse number (50, 100, and 200 pulses) at 30 and 50 Hz were delivered to the ulnar nerve of 10 (5 male, 5 female; 23.4 ± 0.9 years), healthy individuals in random order. Single twitches of the adductor pollicis muscle were elicited before and after each train with a rest interval of at least 5 min between each train. No differences in potentiation occurred across the pulse-matched trains at frequencies of 15-50 Hz (38.9 ± 5.4-44.6 ± 5.5%). Twitch force potentiation following the highest (100 Hz) and lowest (7.5 Hz) frequency trains were not significantly different and were lower than the other 100 pulse-matched trains. As pulse number increased, potentiation increased for both the 30 and 50-Hz trains. There was a significant positive correlation between force potentiation and force-time integral produced by the stimulation train, r = 0.70. The results indicate that potentiation magnitude is dependent on the force-time integral produced during the test train and the number of pulses delivered, independent of stimulation frequency.

    In vitro oxyradical effects on SR Ca2+ regulation were studied by using a SR-containing cell-free preparation from scallop (Pecten jacobaeus) adductor muscle. Ca2+ variations were fluorimetrically detected after incubation with Fluo-3 in the presence of ATP. Exposure to Fe3+/ascorbate produced dose-dependent Ca2+ release from SR vesicles, eventually leading to massive Ca2+ loss. Exposure to hypoxanthine/xanthine oxidase also caused Ca2+ release but at a much slower rate. Pre-incubations with catalase or with the hydroxyl radical scavenger KMBA led to a significant decrease in the Fe3+/ascorbate-induced Ca2+ release rate and to a delay of massive Ca2+ loss. Pre-incubations with GSH or DTT strongly reduced the Ca2+ release caused by Fe3+/ascorbate and, moreover, they prevented massive Ca2+ loss from SR vesicles. Addition of GSH or DTT after Fe3+/ascorbate promptly reduced the Ca2+ release rate and delayed massive Ca2+ release. Pre-incubation with the SR Ca2+ channel blocker ruthenium red strongly reduced the Ca2+ release caused by Fe3+/ascorbate, and also prevented massive Ca2+ loss. In the presence of ruthenium red, Fe3+/ascorbate treatments followed by Ca2+ addition revealed that Ca2+ uptake inhibition was slower than Ca2+ release. Taken together, data showed that free radicals and, in particular, hydroxyl radicals, affected the scallop SR Ca2+ regulation. This mainly occurred through Ca2+ channel opening, most likely triggered by sulfhydryl oxidation, which eventually led to massive Ca2+ release from SR vesicles. The demonstration of a specific effect of oxyradicals on SR Ca2+ channels is in line with their possible involvement in cell signaling.

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 objective was to investigate the applicability of the Dysphonia Severity Index (DSI) and the Voice Handicap Index (VHI) in evaluating effects of intervention between groups of patients and for intrasubject differences and whether DSI and VHI are complementing measurements. Analyses of measurement data before and after intervention of 171 patients with voice disorders. The voice quality was measured objectively with the DSI. The perceived voice handicap was measured with the VHI. Three groups of patients were used: patients who had voice therapy, phonosurgery, or no intervention. DSI and VHI improved significantly after intervention in the voice therapy and the surgery group (median difference DSI 1.19 and 3.03, VHI -8 and -26, respectively). The intrasubject results were analyzed based on the test-retest variability of DSI and VHI. Significant better DSI and VHI scores after intervention were found in, respectively, 22% and 38% of the patients with voice therapy, and 56% and 78% of the patients with surgery. In the no intervention group, this was 11% and 12%. In 37% of the patients, the differences before and after intervention in DSI and VHI were in discordance. The DSI and VHI are able to show significant differences after intervention for voice disorders between groups of patients. The DSI and VHI can be used to determine a significant intrasubject result of intervention. The DSI and VHI measure each different aspects of the voice and are complementing measurements. The DSI is therefore applicable in clinical practice for objective evaluation of voice quality and the VHI for subjective evaluation of the perceived handicap by the patient self.

    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(2)O(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(2)O(2) treatments respectively. 6 and 7 spots were differentially expressed in the adductor muscle for Cd and H(2)O(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.

    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.

    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.

    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.

    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 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.

    @@痉挛性斜颈(spasmodic torticollis,wry neck)或颈肌张力障碍(cervical dystonia)是最常见的限局性肌张力障碍。严格来讲称为颈肌张力障碍较为适宜,因为斜颈强调的是一种体征,不是诊断,并不能突出肌张力障碍的特点,痉挛性斜颈包括肌张力障碍性和非肌张力障碍性两种。特发性颈肌张力障碍(idiopathic cervical dystonia,ICD)是最常见的成人发病的限局性肌张力障碍。ICD的定义是:由于异常的不随意肌收缩引起的颈部不随意性扭曲和转动。因颈部肌肉不随意性持续强直或阵挛性收缩,产生头和颈部的异常姿势,例如旋颈、颈侧倾、颈前屈和颈后仰,或者几种异常的姿势混合在一起。因颈肌张力障碍对侧肌肉的拮抗作用,可出现周期性头颈短暂抽搐或震颤。颈肌张力障碍受累范围常扩大,超过颈区,但一般不发展成为全身性肌张力障碍。大约2/3的病人有颈痛,有时将手放在后头部或下颏部可以缓解斜颈的症状。大约10%的病人有缓解期,通常发生在起病的1年内。多数在缓解的数年之后复发,如不经治疗,症状往往持续不愈。

    The cDNA sequence of the myostatin gene in the Pacific lion-paw Nodipecten subnodosus (Ns-mstn) was characterized, and the temporal expression during grow-out was analyzed for the first time in a scallop. Ns-mstn encodes a 459-amino-acid protein in which two propeptide proteolytic sites were identified, the previously recognized (RSKR) and a second one at position 266-269 aa (RRKR). The alternative furin cleavage site could be related with post-translational processing, or it could be a tissue-specific mechanism for signaling activity. The Ns-mstn transcript was located by in situ hybridization in sarcomeres and around the nucleus of muscle fibers. The temporal expression analysis by qPCR in the adductor muscle showed that Ns-mstn expression was significantly different (P subnodosus as it occurs in vertebrate skeletal muscle although Ns-mstn expression in non-muscle organs/tissues suggests additional functions. © 2015 Wiley Periodicals, Inc.

    Virtual reality (VR) distraction is a nonpharmacological method to prevent acute pain that has not yet been thoroughly explored for anesthesiology. We present our experience using VR distraction to decrease routine intravenous sedation for patients undergoing preoperative perineural catheter insertion. This 1-month quality improvement project involved all elective unilateral primary total knee arthroplasty patients who received a preoperative adductor canal catheter. Clinical data were analyzed retrospectively. For the first half of the month, all patients received usual care; intravenous sedation was administered at the discretion of the regional anesthesiologist. For the second half of the month, patients were offered VR distraction with intravenous sedation upon request. The primary outcome was fentanyl dosage; other outcomes included midazolam dosage, procedure-related pain, procedural time, and blood pressure changes. Seven patients received usual care and seven used VR. In the VR group, 1/7 received intravenous sedation versus 6/7 who received usual care (P = 0.029). The fentanyl dose was lower (median [10th-90th percentiles]) in the VR group (0 [0-20] µg) versus the non-VR group (50 [30-100] µg; P = 0.008). Midazolam use was lower in the VR group (0 [0-0] mg) than in the non-VR group (1 [0-1] mg; P = 0.024). Procedure-related pain was lower in the VR group (1 [1-4] NRS) versus the non-VR group (3 [2-6] NRS; P = 0.032). There was no difference in other outcomes. VR distraction may provide an effective nonpharmacological alternative to intravenous sedation for the ultrasound-guided placement of certain perineural catheters.

    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.

    Full Text Available 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.

    Adductor canal block (ACB) has emerged as an appealing alternative to femoral nerve block (FNB) that produces a predominantly sensory nerve block by anesthetizing the saphenous nerve. Studies have shown greater quadriceps strength preservation with ACB compared with FNB, but no advantage has yet been shown in terms of fall risk. The Tinetti scale is used by physical therapists to assess gait and balance, and total score can estimate a patient's fall risk. We designed this study to test the primary hypothesis that FNB results in a greater proportion of "high fall risk" patients postoperatively using the Tinetti score compared with ACB. After institutional review board approval, informed written consent to participate in the study was obtained. Patients undergoing primary unilateral total knee arthroplasty were eligible for enrollment in this double-blind, randomized trial. Patients received either an ACB or FNB (20 mL of 0.5% ropivacaine) with catheter placement (8 mL/h of 0.2% ropivacaine) in the setting of multimodal analgesia. Continuous infusion was stopped in the morning of postoperative day (POD)1 before starting physical therapy (PT). On POD1, PT assessed the primary outcome using the Tinetti score for gait and balance. Patients were considered to be at high risk of falling if they scored <19. Secondary outcomes included manual muscle testing of the quadriceps muscle strength, Timed Up and Go (TUG) test, and ambulation distance on POD1 and POD2. The quality of postoperative analgesia and the quality of recovery were assessed with American Pain Society Patient Outcome Questionnaire Revised and Quality of Recovery-9 questionnaire, respectively. Sixty-two patients were enrolled in the study (31 ACB and 31 FNB). No difference was found in the proportion of "high fall risk" patients on POD1 (21/31 in the ACB group versus 24/31 in the FNB group [P = 0.7]; relative risk, 1.14 [95% confidence interval, 0.84-1.56]) or POD2 (7/31 in the ACB versus 14/31 in the FNB

    Full Text Available Sabe-se que a respiração oral pode ocasionar diversas alterações ósseas, posturais, musculares e funcionais, como também, alterações na qualidade e/ou comportamento vocal. Estas alterações podem comprometer a comunicação oral, na qual a voz não consegue desempenhar seu papel básico de transmissão da mensagem verbal e emocional do indivíduo. O indivíduo com respiração oral pode apresentar ressonância nasalizada e a voz pode apresentar alterações no traço de sonoridade, hiper ou hiponasal, ou rouca. A partir de pesquisa nas bases de dados LILACS, SciELO, livros, revistas especializadas sobre o tema, buscamos fazer uma revisão na literatura sobre a relação entre respiração oral e disfonia, analisando a influência das alterações causadas pela respiração oral na qualidade e/ou comportamento vocal. No entanto, foi possível observar que a respiração oral promove uma série de alterações estruturais significativas que refletem nas funções estomatognáticas, interferindo também na fonação. Contudo, poucos autores relatam a possível correlação entre esses dois parâmetros (respiração oral e disfonia.It is known that mouth breathing can lead to several bone, postural, muscular and functional alterations, and also changes on vocal quality and/or vocal behavior.

    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.

    Primary muscular Echinococcus infection is very rare without involvement of thoracic and abdominal organs. In this case a 31-year-old man who had a growing mass in the postero-medial part of his right thigh was examined. The mass was diagnosed as hydatid cyst using ultrasound, magnetic resonance imaging (MRI) and serological tests. It was removed surgically and there has been no recurrence one year after the surgery. The MRI imaging characteristics may differ depending on the life cycle stage of the parasite. In this case report, we discuss the imaging characteristics of the muscular hydatid cyst with special emphasis on the MRI findings. In regions where hydatidosis is endemic, a mass found in body muscles should be considered as a muscular hydatid cyst.

    For non-model species, as many used for aquaculture, with minimal or no genomic information, relative quantification of gene expression studies requires preliminary research including the isolation of potential reference genes and the identification of those stably expressed under the biological conditions of interest. Here we report on the isolation of five partial gene sequences from gonad tissue cDNA in the functional hermaphrodite scallop Nodipecten subnodosus to be evaluated as reference genes: 18S-rRNA, riboprotein l8 (rp-l8), actin-β (act-β), elongation factor 1α (ef-1α) and alpha-tubulin-α (tub-α). We found that 18S-rRNA was stably expressed independently of the priming method used to reverse transcribe RNA to cDNA, oligo-dT or random hexamer. Stability analysis for the five putative reference genes with geNorm and NormFinder indicated that 18S together with rp-l8 were the most stable genes for normalization of gene expression during gonad development in both, male and female sexual regions of the hermaphrodite N. subnodosus. The least stable gene was tub-α, showing a biased expression profile between sexual regions of the gonad, therefore this gene was analyzed thereafter as a target gene together with vitellogenin (vit) and a DEAD-box RNA helicase (dbx) gene. Relative expression, estimated by normalization with the combination of 18S and rp-l8 as reference genes, indicated that as gonad development advanced two of the target genes were up-regulated, tub-α in the male region and vit in the female region. Whereas an increased expression was expected during development for vit for its known role in vitellogenesis, the increased expression of tub-α in the male sexual region was unexpected, and pointed toward this gene being a testis-specific α-tubulin isotype. Further analyses of gene expression among tissues indicated that tub-α is specifically and highly expressed in the male gonad, although expression in adductor muscle was also observed at

    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.

  4. A Therapeutic Trial on 12 Cases with Spasmodic Torticollis

    2000-01-01

    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.

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

    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.

    Recently, the Voice Handicap Index (VHI), developed in the United States, has been highlighted as a means to assess a patient's perceptions of the severity of his or her voice disorder. The VHI is based on a self-administered questionnaire that quantifies the degree of a patient's disability related to his/her voice disorder. The questionnaire was translated into Japanese and applied to Japanese patients with various kinds of disordered voice or dysphonia. The results were analyzed and the usefulness discussed. In this study, 546 patients (281 males and 265 females) were included. Mean VHI scores were 36.2/120 in males and 44.1/120 in females. In the male patients, VHI scores were the highest among teens. However, VHI scores did not vary with age in the female patients. Patients with vocal fold paralysis, functional dysphonia, psychological dysphonia, and spasmodic dysphonia showed relatively high VHI scores, whereas those with laryngeal granuloma and laryngopharyngeal reflux disease showed low scores. In most diseases, functional and physiological scores were higher than emotional scores. In any treated patients, those with vocal nodule, vocal polyp, polypoid vocal fold, and recurrent laryngeal nerve paralysis, VHI scores decreased after therapeutic intervention. These findings suggest that the Japanese VHI is a useful tool for monitoring a patient's psychological status, choosing appropriate treatment, and assessing the therapeutic outcome.

    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.

    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.

    Intensive microearthquake swarms with the appearance of volcanic tremor have been observed in the southwest part of Long Valley caldera, southeastern California. This activity, possibly associated with magma injection, began 6 weeks after several strong (magnitude 6+) earthquakes in an area south of the caldera and has continued sporadically to the present time. The earthquake sequence and magmatic activity are part of a broad increase in tectonic activity in a 15,000-square-kilometer region surrounding the White Mountains seismic gap, an area with high potential for the next earthquake in the western Great Basin.

    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.

Therefore, the objective of this research was to investigate the effect of Euphorbia spinidens Bornm. Ex Prokh. on motility of rat uterus. Uterine horns were isolated form non-pregnant female rats pretreated with estrogen. E. spinidens hydroalcoholic extract was examined on KCl (80 mM) induced and spontaneous periodic contraction in isolate uterine strips suspended in an organ bath and compared with nifedipine and ritodrine. In isolated rat uterine strips, E. spinidens extract (1-500 µg/mL) showed mixed effects. At lower concentrations, firstly potentiated the spontaneous periodic contraction, while in concentrations above 256 µg/mL the spontaneous periodic contractions were completely attenuated. These findings demonstrated that although lower concentrations of hydroalcoholic extract potentiated the spontaneous periodic contraction of rat uterine smooth muscle, but at higher concentrations it had inhibitory effect on rat uterus contraction.

The mass and magnetic flux accumulating in the forming star are calculated, as are their effects on the structure & evolution of the surrounding disk. The numerical method of solution first uses an adaptive grid and later, after a central region a few AU in radius becomes opaque, switches to a stationary but nonuniform grid with a central sink cell. It also involves an implicit time integrator, an advective difference scheme that possesses the transportive property, a second-order difference approximation of forces inside a cell, an integral approximation of the gravitational and magnetic fields, and tensor artificial viscosity that permits an accurate investigation of the formation and evolution of shocks in the neutral fluid.

    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.

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

    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.

    Although an association between psychosocial distress (depression, anxiety, somatization, and perceived stress) and voice disorders has been observed, little is known about the relationship between distress and patient-reported voice handicap. Furthermore, the psychological mechanisms underlying this relationship are poorly understood. Perceived control plays an important role in distress associated with other medical disorders. The objectives of this study were to (1) characterize the relationship between distress and patient-reported voice handicap and (2) examine the role of perceived control in this relationship. This is a cross-sectional study in a tertiary care academic voice clinic. Distress, perceived stress, voice handicap, and perceived control were measured using established assessment scales. Association was measured with Pearson correlation coefficients; moderation was assessed using multiple hierarchical regression. A total of 533 patients enrolled. Thirty-four percent of the patients met criteria for clinically significant distress (ie, depression, anxiety, and/or somatization). A weak association (r = 0.13; P = 0.003) was observed between severity of psychosocial distress and vocal handicap. Present perceived control was inversely associated with distress (r = -0.41; P relationship between voice handicap and psychosocial distress was moderated by perceived control (b for interaction term, -0.15; P < 0.001); greater vocal handicap was associated with greater distress in patients with low perceived control. Severity of distress and vocal handicap were positively related, and the relation between them was moderated by perceived control. Vocal handicap was more related to distress among those with low perceived control; targeting this potential mechanism may facilitate new approaches for improved care.

    A patient's self-assessment of his/hers vocal problem and the analysis of the results of a treatment are means used to verify the effectiveness of an intervention and to develop directive procedures for clinical health practice. Psychometric instruments are the most common tools used to perform this task. Validation of self-assessment instruments may be carried out in several ways; however there should be clear and structured criteria involved in this process. To present the validation process of three voice self-assessment instruments for the Brazilian Portuguese language: Voice-Related Quality of Life--V-RQOL, Voice Handicap Index--VHI and, Voice Activity and Participation Profile--VAPP. These instruments received respectively the following names: Qualidade de Vida em Voz - QVV, Indice de Desvantagem Vocal--IDV and Perfil de Participação e Atividades Vocais--PPAV, emphasizing their specificities and the necessary adaptations for their use in Brazil. The three questionnaires were validated following the guidelines suggested by the Scientific Advisory Committee of Medical Outcomes Trust--SAC. The psychometric measures of validity, reliability, reproducibility and sensitiveness were statistically demonstrated for each instrument. The Brazilian versions of the V-RQOL, VHI and VAPP demonstrated to be valid, reliable and sensitive instruments that specifically assess patients who present voice problems. These instruments can be used in the assessment of the life quality related to voice, as well as for the analysis of treatment outcomes.

    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.

    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.

    2010-10-01

    Dysarthria refers to a collective name for a group of neurologic motor speech disorders, resulting from central and/or peripheral nervous system abnormalities. Speech alteration in Parkinson's disease, so-called hypokinetic dysarthria, presents with prosodic insufficiency, related to a monotony of pitch and intensity, a reduction of accentuation, variable speech rate and possible phoneme imprecision. In most cases, voice is harsh and breathy. This symptom can affect both voice and speech quality, as well as prosody and intelligibility. As a consequence, many patients complain about speech impairments, which affect their communication in daily living activities. Perceptual and instrumental assessments require different and numerous investigation methods, which use may help to further understand the specific dysarthria pathophysiology. This is of importance in order to adjust treatments for dysarthria; as a matter of fact, dopa-therapy, functional neurosurgery or even behavioural speech therapy have variable effects on voice and speech quality in Parkinson's disease.

    2009-09-01

    Full Text Available Abstract Introduction Although recurrent laryngeal nerve injury has been described following central venous access via the jugular route, it has not previously been reported following access via the subclavian route. Case presentation A 63-year-old man presented with acute dysphonia immediately after insertion of a Hickman line via the subclavian route. Flexible laryngoscopy revealed a left vocal fold palsy. A computed tomography scan from the skull base to the thoracic inlet showed no obvious abnormality other than an abducted left vocal cord. The timing of the events and the computed tomography scan results strongly support the conclusion that the left recurrent laryngeal nerve was injured during insertion of the Hickman line, resulting in a left adductor vocal cord palsy. Conclusion This case illustrates an unusual example of iatrogenic injury to the recurrent laryngeal nerve. It is important to recognize the possibility that such injuries may occur in order to prevent them.

    Full Text Available Abstract Background Myrsine africana is an herbaceous plant that is traditionally used as appetizer and carminative. Locally, it is used for the treatment of pulmonary tuberculosis, rheumatism and diarrhea by healers. The aims of the current study were to screen the crude methanol extract obtained from the aerial parts (leaves and stem of M. africana, for antispasmodic actions on isolated tissues and further to subject the ethyl acetate (EtOAc fraction of plant to column chromatography for isolation of pure compounds. Methods The antispasmodic action of the crude methanol extract was measured on the spontaneous rabbit's jejunum preparations at concentration 0.01, 0.03, 0.1, 0.3, 1.0, 5.0 and 10.0 mg/ml. The crude extract was also applied, in similar concentrations, on KCl (80 mM induced contractions to explain its possible mode of action. Results A new compound Myrsigenin was isolated from the EtOAc fraction of M. africana. The structure of the compound was identified with the help of 13C-NMR, 1H-NMR, HMBC, HMQC, NOESY and COSY. The plant crude methanol extract showed a significant antispasmodic action on rabbit jejunum and abolished the tissue contraction completely at concentration of 5.0 mg/ml. Conclusion The study concludes that the methanol crude extract of aerial parts of M. africana has antispasmodic action possibly through the calcium channel blocking mechanisms. A new compound Myrsigenin was isolated from the EtOAc fraction of the plant.

  3. Wavelet adaptation for automatic voice disorders sorting.

    Early diagnosis of voice disorders and abnormalities by means of digital speech processing is a subject of interest for many researchers. Various methods are introduced in the literature, some of which are able to extensively discriminate pathological voices from normal ones. Voice disorders sorting, on the other hand, has received less attention due to the complexity of the problem. Although, previous publications show satisfactory results in classifying one type of disordered voice from normal cases, or two different types of abnormalities from each other, no comprehensive approach for automatic sorting of vocal abnormalities has been offered yet. In this paper, a solution for this problem is suggested. We create a powerful wavelet feature extraction approach, in which, instead of standard wavelets, adaptive wavelets are generated and applied to the voice signals. Orthogonal wavelets are parameterized via lattice structure and then, the optimal parameters are investigated through an iterative process, using the genetic algorithm (GA). GA is guided by the classifier results. Based on the generated wavelet, a wavelet-filterbank is constructed and the voice signals are decomposed to compute eight energy-based features. A support vector machine (SVM) then classifies the signals using the extracted features. Experimental results show that six various types of vocal disorders: paralysis, nodules, polyps, edema, spasmodic dysphonia and keratosis are fully sorted via the proposed method. This could be a successful step toward sorting a larger number of abnormalities associated with the vocal system. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Symptomatic dystonia can be the result of various metabolic, degenerative diseases, the consumption of certain medications or exposure to toxic agents. However, only symptomatic dystonia with focal structural lesion provides a significant "window" for, at least indirect, perception of aetiopa-thogenesis and pathomorphological substratum of idiopathic dystonia. Our study included 57 patients with symptomatic dystonia, which as a base had focal or multifocal lesions, of whom 7 patients had generalized dystonia, 18 hemidystonia, 6 segmental dystonia, 7 torticollis, 6 blepharospasm, 7 hand dystonia, 3 spasmodic dysphonia, and 3 had oromandibular dystonia. Stroke was highly statistically the most frequent cause of structural lesions (33/57 or 58%. Relevant pathomorphological changes were present in 50/57 (88% patients, of whom 25 (50% had lesion in the lenticular nucleus (including individual damage of the putamen and globus pallidus, 12/50 (24% had damage of the thalamus and 6/50 (12% had damage of the brainstem. Generalized dystonia was most frequently associated with bilateral lesion of the putamen, hemidystonia with lesion of contralateral putamen, torticollis with damage of the caudate nucleus, hand dystonia with lesion of the thalamus and blepharospasm with lesion of the upper brainstem.

    Full Text Available Palatal myoclonus is a rare cause of pulsatile tinnitus in patients presenting to the otolaryngology office. Rhythmic involuntary contractions of the palatal muscles produce the pulsatile tinnitus in these patients. Treatment of this benign but distressing condition with anxiolytics, anticonvulsants, and surgery has been largely unsuccessful. A few investigators have obtained promising results with botulinum toxin injection into the palatal muscles. We present a patient with palatal myoclonus who failed conservative treatment with anxiolytics. Unilateral injection of botulinum toxin into her tensor veli palatini muscle under electromyographic guidance resolved pulsatile tinnitus in her ipsilateral ear and unmasked pulsatile tinnitus in the contralateral ear. A novel method of following transient postinjection symptoms using a diary is presented in this study. Botulinum toxin dose must be titrated to achieve optimal results in each individual patient, analogous to titrations done for spasmodic dysphonia. Knowledge of the temporal onset of postinjection side effects and symptomatic relief may aid physicians in dose titration and surveillance. We present suggestions on titrating the botulinum toxin dose to optimal levels. A review of the literature on the use of botulinum toxin for palatal myoclonus and some common complications are discussed.

    Objective: This work aimed to evaluate the cortical silent period (cSP) of the laryngeal motor cortex (LMC) using the bilateral thyroarytenoid (TA) muscles with transcranial magnetic stimulation (TMS). Methods: In 11 healthy participants, fine-wire electromyography (EMG) was used to record bilateral TA muscle responses to single pulse TMS delivered to the LMC in both hemispheres. Peripheral responses to stimulation over the mastoid, where the vagus nerve exits the skull, were collected to verify the central origin of the cortical stimulation responses by comparing the latencies. Results: The cSP duration ranged from 41.7 to 66.4 ms. The peripherally evoked motor-evoked potential (MEP) peak occurred 5–9 ms earlier than the cortical responses (for both sides of TAs: p < 0.0001) with no silent period. The right TA MEP latencies were earlier than the left TA responses for both peripheral and cortical measures (p ≤ 0.0001). Conclusion: These findings demonstrate the feasibility of measuring cSP of LMC based on intrinsic laryngeal muscles responses during vocalization in healthy volunteers. Significance: The technique could be used to study the pathophysiology of neurological disorders that affect TA muscles, such as spasmodic dysphonia. Further, the methodology has application to other muscles of the head and neck not accessible using surface electrodes. PMID:28326007

The aim of the presented study is to confirm a decrease in praepubic 18F-FDG accumulation in response to therapy and to describe potential correlations to other 18F-FDG PET/CT scan characteristics during the course of disease. As a secondary objective, we describe the pathological aspects of the observed praepubic 18F-FDG uptake.

    The purpose of this study was to assess the long-term development of children with cerebral palsy treated with soft tissue releases of the hip and, if necessary, also of the hamstrings and the Achilles tendon. The follow-up had to consider the functional status and the hip centration. Seventy-one patients (46 with tetrapareses, 24 with dipareses, and one with triparesis) who underwent soft tissue releases of the hip by the so-called psoas-rectus transfer at an average age of 7 years were assessed preoperatively, after 1 year and at an average age of 19 years. Functional status and the radiological lapse were assigned. The functional status of the patients significantly improved (P<0.001) after surgery. The number of patients who were able to walk increased from 49.3 to 80.3%. The migration percentage decreased from 26.6 to 17.3%. For medium-to-severe functional deficits, a clear gain of function and a safe prevention of spastic hip luxation were achieved.

  1. Art and dystonia.

    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. Copyright © 2015 Elsevier B.V. All rights reserved.

    Background 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. Methods 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. Results 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. Conclusions 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. PMID:27171035

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

    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.

    Full Text Available OBJETIVO: Avaliar os efeitos da fonoterapia nos distúrbios da voz por meio de diferentes parâmetros acústicos pré e pós-fonoterapia. MÉTODOS: Trata-se de estudo experimental retrospectivo no qual se analisou as gravações de vozes de 67 indivíduos submetidos à reabilitação vocal. Os espectrogramas pré e pós-terapia fonoaudiológica foram julgados por quatro fonoaudiólogas. Os parâmetros para análise foram: forma do traçado, grau de escurecimento dos harmônicos, estabilidade do traçado dos harmônicos, presença de ruído, presença de harmônicos e de sub-harmônicos. Os dados obtidos foram submetidos a análise estatística, em que também se buscou observar a eventual diferença de padrões entre gêneros e diagnósticos. RESULTADOS: Não houve diferença estatisticamente significante entre a forma do traçado espectrográfico nas condições pré e pós-fonoterapia, porém a maioria dos pacientes (58% obteve melhora. O grau de escurecimento manteve-se estável nas condições pré e pós-fonoterapia (p=0,000.

Não houve relação entre o gênero do paciente e o grau de melhora espectrográfica. Em relação ao diagnóstico, apenas o parâmetro forma do traçado apresentou diferenças significativas. CONCLUSÃO: Apesar de não terem sido encontradas mudanças significativas em todos os parâmetros avaliados, a espectrografia acústica demonstrou ser um instrumento eficaz para avaliar a evolução da voz do paciente no processo terapêutico, sendo complementar à avaliação perceptivo-auditiva e fazendo parte de um protocolo multidimensional.PURPOSE: To evaluate the effects of vocal therapy on voice disorders using different spectrographic parameters, before and after therapy. METHODS: This experimental retrospective study analyzed voice recordings of 67 dysphonic patients that had attended vocal therapy. Pre- and post-treatment spectrograms were analyzed by four speech-language pathologists. The following parameters were analyzed: spectrogram regularity, harmonic colors, spectrogram stability, presence of noise components, presence of harmonic and sub-harmonics. Data were submitted to statistical analysis, which aimed at identifying different patterns between genders and diagnoses. RESULTS: There was no difference between pre and post-therapy conditions for spectrogram regularity, however, most patients (58% showed improvement. Harmonic colors remained stable (p=0.000. Significant improvement was observed, after voice therapy, regarding spectrogram stability (p=0.006, and presence of noise (p=0.007, harmonics (p=0.000 and sub-harmonics components (p=0.001. 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.

    A method is proposed for hydrodynamic studies of wells in beds including the termination of the coefficient of piezoconductance by spasmodic change in pressure in the well. It is distinguished by the fact that in order to reduce the time for idling of the well, above the studied bed an output meter is installed and the output of the bed fluid is measured during the time from spasmodic change in pressure to establishment of the stationary output.

    The biological system reaction on spasmodic change of a phase of sine wave revolting force is investigated. The model researches for the biosystem unit that is described by linear differential equation of the second order are carried out. Possibility of time asymmetry in adaptation and transitional processes of biological units, at spasmodic change of phase identical modulo and opposite on the sign is shown. The residual in time of adaptation depends on state of biosystem's unit at the moment of perturbation.

  11. 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.

  12. HOARSENESS AMONG SCHOOL-AGE CHILDREN

    Full Text Available Background. The prevalence of dysphonia in schoolchildren has been reported to be from 7.1% to 23.3% and in adolescents from 0 to 80%. In Slovenia, the study on prevalence of dysphonia in schoolchildren has not been performed yet.Methods. The voice samples of 100 4th-graders and 102 8thgraders of elementary school were recorded. A lay judge and a professional assessed independently degree of hoarseness in the voice samples. One to three months after the recording, the dysphonic children were invited to an otorhinolaryngologic examination in order to find out the cause of dysphonia. All children and their parents answered the questionnaires on illnesses and vocal habits that might cause hoarseness. The prevalence of these unfavourable factors was compared between the group of children with long lasting hoarseness and the children without it.Results. At voice samples’ recording there were 34.2% dysphonic children. One to three months later, there were still 14.9% children with hoarse voice. The most frequent causes for acute dysphonia were acute respiratory infection and exacerbation of chronic laryngitis. The most frequent causes for persistent dysphonia were allergic catarrhal laryngitis, muscle tension dysphonia with or without vocal nodules and mutational voice disorder. The fast speaking rate appeared to be characteristic for children with long lasting dysphonia.Conclusions. Dysphonia in school-age children is the result of diseases of upper respiratory tract and/or functional voice disorders. Both causes of dysphonia could be successfully treated if they are detected early and the children are advised to see an otorhinolaryngologist. Adolescence is an ideal period for treatment of functional voice disorders. It is also the period when the children must decide for their future profession.

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.

    Quantitative autoradiographic analysis of receptors for GABA and acetylcholine in the forebrain of rats flown on COSMOS 2044 was undertaken as part of a joint US-Soviet study to determine the effects of microgravity on the central nervous system, and in particular on the sensory and motor portions of the forebrain. Changes in binding of these receptors in tissue from animals exposed to microgravity would provide evidence for possible changes in neural processing as a result of exposure to microgravity. Tritium-labelled diazepam and Quinuclidinyl-benzilate (QNB) were used to visualize GABA (benzodiazepine) and muscarinic (cholinergic) receptors, respectively. The density of tritium-labelled radioligands bound to various regions in the forebrain of both flight and control animals were measured from autoradiograms. Data from rats flown in space and from ground-based control animals that were not exposed to microgravity were compared.

  20. Computer modeling of the pathomechanics of spastic hip dislocation in children.

    1999-01-01

    Spastic muscles about the hip cause subluxation, dislocation, and lead to acetabular dysplasia. Spastic hip disease occurs when the muscles about the hip exert forces that are too high or in the wrong direction or both. To determine the role of the hip forces in the progression of spastic hip disease and the effect of both muscle-lengthening and bony reconstructive surgeries, a computerized mathematical model of a spastic hip joint was created. The magnitude and direction of the forces of spastic hips undergoing surgery were analyzed preoperatively and postoperatively to determine which procedure is best suited for the treatment of spastic hip disease. The muscle-lengthening procedures included (a) the adductor longus, (b) the psoas, iliacus, gracilis, adductor brevis, and adductor longus, and (3) the psoas, iliacus, gracilis, adductor brevis, adductor longus, semimembranosus, and semitendinosus. The bony reconstructive and muscle-lengthening procedures included (a) lengthening the psoas, iliacus, gracilis, adductor brevis, adductor longus, semimembranosus, and semitendinosus combined with changing femoral neck anteversion from 45 to 10 degrees , (b) lengthening of the psoas, iliacus, gracilis, adductor brevis, adductor longus, semimembranosus, and semitendinosus combined with changing neck-shaft angle from 165 to 135 degrees , and (c) lengthening of the psoas, iliacus, gracilis, adductor brevis, adductor longus, semimembranosus, and semitendinosus combined with changing femoral neck anteversion from 45 to 10 degrees and neck-shaft angle from 165 to 135 degrees . Results show that a child with spastic hip disease has a hip-force magnitude 3 times that of the a child with a normal hip in the normal physiologic position. Based on this mathematical model the best to normalize the magnitude of the hip-joint reaction force, the muscles to be lengthened should include the psoas, iliacus, gracilis, adductor brevis, and the adductor longus. To normalize the direction of

    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.

    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.

    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.

    Complex voice assessment due to European Laryngeal Society proposals (2000) contains voice self estimation based on the Polish version of the Voice Handicap Index (VHI). This study focuses on the relation between voice handicap and smoking in dysphonic patients, who are using voice professionally. Thirty outpatient (25 female and 5 male, aged 40 to 55 years) voice department attendees suffering from professional dysphonia took part in this study. All patients after phoniatric examination completed the Polish version of the Voice Handicap Index (VHI). The questions concern functional, emotional and physical complains due to dysphonia. Most of smokers did not complain of dysphonia related problems comparing to non smokers. Even the scores of functional and emotional scales of VHI in smokers shown better results (less handicap) than in nonsmokers. Smoking does not affect patients handicap due to dysphonia measured in the Voice Handicap Index.

    2000-02-01

    The authors present a study of 37 patients affected by monolateral vocal cord paralysis in order to analyze etiology, degree of dysphonia and possible recovery of vocal function. The patients underwent the following tests: case history to determine the vocal characteristics prior to the lesion; video-laryngoscopy to define the position of the paralytic cord on the horizontal glottic plane and any compensation mechanisms; determination of the degree of dysphonia (light, moderate, severe, aphonia) on the basis of psycho-perceptive parameters; spectrography evaluated in classes (I, II, III and IV) according to Yanagihara. Analysis of the data obtained makes it possible to draw the following conclusions: the most frequent etiology encountered by the otorhinolaryngologist is surgical (particularly subsequent to thyroidectomy); the position taken by the paralytic vocal cord does not appear to determine the degree of dysphonia; during the period immediately after occurrence of the lesion (0-4 months) the vocal disorder is more intense and tends to be reduced thereafter, attenuated by a spontaneous compensation mechanism. In this regard, it must be pointed out, however, that such compensation can prove bad or even dangerous for good vocal function (falsetto voice); speech therapy makes it possible to nearly totally normalize vocal function in all patients presenting moderate dysphonia and in 60% of those with severe dysphonia. In the remaining 40% of those patients with severe dysphonia a partial improvement of vocal function was seen (from severe dysphonia to moderate dysphonia). This was determined by the fact that several negative prognostic factors came into play simultaneously in these patients (i.e. advanced age, longer time gap since the lesion occurred, position assumed by the paralytic cord) which prevented them from achieving better phonatory results.

  11. Observations of two special kinds of tremor at Galeras volcano, Colombia(1989-1991

    F. Gil-Cruz

    1999-06-01

    Full Text Available Since the reactivation of Galeras volcano in 1988 its seismic activity has been dominated by a variety of LP waveforms and tremor events. Some of these signals occurred as a response to volcanic activity. Among them, two kinds of tremor deserve special attention, Flute tremor and Spasmodic tremor. Flute tremor has a spectrum of equally spaced peaks and is associated with a quasi-steady degassing process at the top of the lava dome. It is accompanied by a flute-like sound. Its spectral features and the correlation with field observations are consistent with a model generation indicating that a crack or set of cracks are excited to resonance by the release and flow of gas through the lava dome. Spasmodic tremor is composed of several distinct LP-like events joined together by a continuous signal with lower amplitudes. Two types of spasmodic tremor may be distinguished on the basis of their spectral characteristics and field observations. Spasmodic tremor type I is apparently dominated by a mix of P, SH and Rayleigh waves as determined from preliminary polarization analysis. The source appears to be located, in a region west of the active crater. As a first approximation, Spasmodic tremor type I could be associated with magmatic intrusion process occurred in 1989-1991.

    There has been considerable recent research into the connection between Parkinson's disease (PD) and speech impairment. Recently, a wide range of speech signal processing algorithms (dysphonia measures) aiming to predict PD symptom severity using speech signals have been introduced. In this paper, we test how accurately these novel algorithms can be used to discriminate PD subjects from healthy controls. In total, we compute 132 dysphonia measures from sustained vowels. Then, we select four parsimonious subsets of these dysphonia measures using four feature selection algorithms, and map these feature subsets to a binary classification response using two statistical classifiers: random forests and support vector machines. We use an existing database consisting of 263 samples from 43 subjects, and demonstrate that these new dysphonia measures can outperform state-of-the-art results, reaching almost 99% overall classification accuracy using only ten dysphonia features. We find that some of the recently proposed dysphonia measures complement existing algorithms in maximizing the ability of the classifiers to discriminate healthy controls from PD subjects. We see these results as an important step toward noninvasive diagnostic decision support in PD.

  13. Analysis of friction self-oscillations of a drilling string with the exponential law of resistance

    An analysis of the friction self-oscillations in the drilling string based on the exponential law of resistance with. A spasmodic law of resistance was obtained from it as a particular case. It is indicated that for definite parameters, the amplitude of self-oscillations with expoential law of resistance exceeds the scope of oscillations with spasmodic law. Dependences were constructed for the period of self-oscillations and time for motion from these parameters. Dangerous modes of friction self-oscillations were defined.

  14. Conversion “V” Profiles in Torticollis

    Full Text Available The assumption that spasmodic torticollis represents a conversion reaction was examined by evaluating profiles of 61 patients on the hypochondriasis, depression, and hysteria scales of the Minnesota Multiphasic Personality Inventory. Thirty-six per cent of the sample had normal profiles. A conversion “V” profile with scores above 70 was found in a minority (9% of the patients. The profile of the majority of the group was characterized by the presence of mild depression. It was concluded that a personality profile suggestive of conversion reaction is not typical of patients with spasmodic torticollis.

    Fourteen patients with spasmodic torticollis and other segmental dystonic syndromes, who were refractory to previous forms of therapy, were selected for treatment with drugs intended to elevate brain gamma-aminobutyric acid (GABA) levels. These patients were simultaneously given diazepam, isoniazid, pyridoxine, and large doses of L-glutamine. Involuntary spasmodic activity improved to varying degrees in 7 patients; in 2 the dyskinesia became worse. Transient alteration of renal or hepatic function occurred in 6 patients and mild euphoria unrelated to neurological improvement in 8. Two patients are still being treated. Deficiency of GABA may be a factor in some patients with these disorders.

    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.

    The topography and structures of the femoral triangle are presented. The femorai triangle lies between the inguinal ligament at the base, the sartoriusmuscle at the lateral border and the long adductor muscle at the medial border. The apex of the femoral triangle is situated at the meeting point of the medial borders of the sartorius and long adductor muscles. The subinguinal space, which is divided into the lacuna musculorum and lacuna vasorum, provides a passageway for the lateral cutaneous...

  19. [The importance of soft tissue stabilization in trans-femoral amputation].

    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.
