[Oral DMSO therapy in 3 patients with lipoidproteinosis. Results of long-term therapy].

Lipoid proteinosis is a rare autosomal recessive disorder with a chronic, benign course. There is no generally accepted systemic therapy apart from the experimental oral use of dimethyl sulphoxide (DMSO) and etretinate in two single cases. We treated two sisters and an unrelated man with lipoid proteinosis with longterm oral DMSO (60 mg/kg/d). At the end of an average treatment time of 3 years, DMSO was withdrawn because it produced no beneficial effects with regard to their skin, mucosal lesions or hoarseness. Additionally, one patient showed progression of her disease with worsening hoarseness and onset of dyspnea, requiring surgical removal of vocal cord infiltrates. Three patients with lipoid proteinosis failed to show any beneficial response to long term treatment with DMSO.

[Chronic hyperplastic laryngitis following treatment of hypertension with angiotensin converting enzyme-inhibitor].

We report the case of a 42 year old patient who developed chronic hyperplastic laryngitis during treatment with the angiotensin converting enzyme-inhibitor Cibacen 10. A severe cough and vocal restrictions with hoarseness were only incompletely cured after changing this anti-hypertensive medication to a adrenergic blocker, combined with a vocal rest and anti-inflammatory inhalation. Therefore we performed a laryngoscopy under general anesthesia and excised the swelling of the vocal cords. Additionally, voice therapy was prescribed and complete restitution achieved. Although hoarseness is documented as a potential side effect of angiotensin converting enzyme-inhibitors, morphological alterations in the vocal cords have not been linked to this type of drug. In our case, prolonged medication with Cibacen 10 led to chronic hyperplastic laryngitis. Initial coughing might have induced the trauma of the epithelium of the vocal cords. Due to the morphological alterations to the vocal cords the patient developed additional functional dysphonia.

Recurrent laryngeal nerve damage and phonetic modifications after total thyroidectomy: surgical malpractice only or predictable sequence?

Modifications of phonation occurring after total thyroidectomy (TT) are usually attributed to surgical malpractice, but other causes of voice impairment even in nonoperated subjects should also be taken into account. This study analyzes 208 patients who underwent TT from January 1, 1999 through December 31, 2001. Follow-up ended on December 31, 2003. Only cases in which the surgeon ruled out the possibility of operative damage to the laryngeal nerves were included. All patients underwent pre- and postoperative clinical and instrumental nose and throat examination (NTE). Preoperatively, 86 patients (41%) showed hoarseness or dysphagia: 4 (2%) monoplegia and 12 (6%) hypomobility of the vocal cords due to impaired function of the recurrent laryngeal nerve (RLN); 6 (3%) cord hypotonia due to impairment of the superior laryngeal nerve (SLN); 34 (16%) dysphagia: and 30 (14%) hoarseness due to other causes. At follow-up 1 month after surgery, 71 patients (34%) had an onset of previously absent signs and symptoms: 8 (4%) had palsy of one vocal cord (2% permanent); 6 (3%) had cord hypomobility (all temporary); 12 (6%) had cord hypotonia due to disease of the SLN, 4 of which (2%) were permanent; 44 patients (21%) had symptoms due to scarring and adhesions between the laryngotracheal axis and the prethyroid muscles and between these and the skin. One patient (0.5%) had a nodular cord lesion that occurred after 3 months. Overall, more than one-third of the patients had preoperative voice modifications or swallowing impairment, around one-third had these problems after TT, and less than one-third were free of pre- and postoperative complications. The surgeon's care to avoid damage to the anatomica integrity of the of laryngeal nerves does not exclude functional problems of the nerves and of laryngeal dynamics. In fact, such problems could be referred to outcomes linked to the operation itself (hematoma, edema, scarring adhesion) or to events that only temporarily follow surgery but must be considered as an unavoidable sequel (e.g., neuritis, viral neuritis, myopathy). The patient should undergo a careful clinical and instrumental NTE to detect conditions prior to surgery, and the information provided by the surgeons should be thorough to allow the patient to be aware of all possible sequels and consequences.

Flexible, tapered-tip tube facilitates conventional orotracheal intubation by novice intubators.

Orotracheal intubation is the standard technique for airway management, but several untoward airway complications are possible with this method. To avoid airway trauma caused by the tube tip during intubation, the Parker Flex-Tip tube (PFT), which has a flexible, tapered tip, was developed. It has been reported that the PFT facilitates fiberoptic orotracheal intubation and introducer-guided tracheal intubation. In this study, we compared the PFT to a standard endotracheal tube (SET), regarding the time of intubation during conventional orotracheal intubation and the incidence of postoperative sore throat and hoarseness. One hundred and thirty-four patients scheduled for elective anesthesia using orotracheal intubation were randomized to either the PFT or SET and 132 completed the study. The intubators were classified into three groups: staff anesthesiologists, inexperienced anesthesiologists, and anesthesia trainees. The tube was selected by another anesthesiologist and the time required for intubation was measured. PFT did not shorten the time required for intubation and did not reduce the incidence of sore throat and hoarseness. However, a detailed analysis revealed that the PFT decreased the time required for intubation in the anesthesia trainee group. The PFT may help novice intubators to conduct a smooth intubation.

Vocal problems among aerobic instructors and aerobic participants.

A questionnaire to determine the characteristics of vocal problems was distributed to 75 female aerobic instructors and 75 female aerobic participants ranging in age from 20 to 40 years. Of the questionnaires returned, 50 from each group, with completed replies to all questions, were selected for inclusion in the study. The questionnaires, constructed by the investigator, included pertinent questions relative to length of teaching/participating experience, average number of classes taught/participated in weekly, number of classes taught/participated sequentially, type of aerobics, medical history and history of vocal problems and/or conditions, water intake daily and during instructing/participating, sleep habits, and smoking habits. The results indicated that aerobic instructors generally experienced more hoarseness and episodes of voice loss during and after instructing and a significantly higher prevalence of nodules. The group differences in reported unrelated episodes of hoarseness, however, were quite similar. The results suggest that aerobic instructors experience a higher prevalence of vocal problems when compared to individuals participating in aerobics.

Voice disorders in children.

The pediatric otolaryngologist has an especially important role in the differential diagnosis and treatment of two voice disorders; these are the voice quality problems (dysphony) and the resonance problems (rhinophony). The first step in the examination is to preclude the organic causes. The functional dysphonia is mostly related to voice abuse/misuse, but may be present on a psychosomatic basis; environmental factors can also play a role in the etiology and the personality structure has been found to be very relevant. The perceptual evaluation of voice is of obvious importance. Endoscopy with a transnasal flexible scope makes it possible, in practically all cases, to identify the morphodynamic changes. Stroboscopy and phonetography can be carried out only in older children, sometimes a 'trial treatment' is of valuable help. The therapy can be divided into five groups (counselling, voice re-education, drug treatment, psychotherapy, surgery), but should be always individual. An open question: how to choose the preferable treatment of vocal nodules: surgery, conservative or wait-and-see? According to a detailed survey in Kurume University Hospital the following can be stated: if the patient is in trouble due to hoarseness, and immediate improvement of his voice is necessary, surgery should be indicated; if they need the improvement but do not need it urgently, voice therapy is recommended; without motivation vocal hygiene is proposed. No matter what treatment patients receive, their voices improve in the majority after puberty, but 15% of the patients do not show any improvement. In cases of hoarseness due to long-term postintubational glottic lesions logopedic treatment is the only therapeutic possibility. The delay of speech development of tracheotomized children can and should be avoided by applying proper cannula technique and by logopedic training. The physiological nasality which depends upon the undisturbed activity of the velopharyngeal closure, can become pathologic in four forms: closed, open, mixed and alternating nasality (rhinophonolalia). In the diagnosis of hyperrhinophony due to VPI X-ray procedures, supplemented with nasendoscopy, proved to be the most informative methods, the etiology (neuromyogen processes) may be revealed by electrophysiological methods; the voice and speech can be assessed and visualized by nasometry, but the detailed speech evaluation is indispensable. The basic possibilities of treatment are as follows: speech therapy, surgery, speech bulb, electrotherapy and medicines. The basis of operative treatment is flap surgery. The anatomical result of 1000 (velo) pharyngoplasties carried out in Madarász and Heim Pál Children's Hospital (Budapest) is good in 98%, the hyperrhinophony ceased or became minimal in 90% after surgery. The ideal age for operation is 4.5 years.

Survival predictors in advanced non-small cell lung cancer.

The authors studied the influence on survival of 21 clinical, anatomical, haematological and biochemical factors evaluated, at diagnosis, of 411 patients (pts) with advanced Non Small Cell Lung Cancer (NSCLC) followed in our department between 1984 and 1990. Most of the patients were male (347--84.4%) and only 64 (15.6%) were females. Median age was 62 years, but was slightly higher in females. Only 34 patients were aged under 45 years. Squamous cell carcinoma (215 pts--52%) and adenocarcinoma (152 pts--37%) were the most frequent histologic types. Performance status was poor--only 103 (25%) continued active; 120 (29%) spent at least half of the time in bed; 188 (46%) were severely limited. After staging, 179 (44%) presented locally advanced disease (stage IIIB) and 232 (56%) metastatic dissemination (stage IV). Therapy was defined by the oncologic group according to individual characteristics and based on clinical grounds. Anti-neoplastic therapy was performed in 225 (55%), chemotherapy alone in 121 (30%), radiation therapy alone in 67 (16%), and sequential combined treatment (chemotherapy and thoracic radiation) in 37 (9%). Until 1987, the main chemotherapy regimen was MACC (Metrotrexate + Adriamycine + Cyclophosphamide + Lomustin), afterwards VP(M) (Cisplatin + Vimblastin + Mitomycine). Radiation therapy was performed using Co60, 2 Gy/day, 5 days a week, for 4 weeks (approximately 45 Gy total). The response rate was poor--four complete responses (2%), 42 (19%) partial responses. The overall median survival was 4.3 months and only 5% of patients were alive after 18 months of follow up. Prognostic importance of each characteristic studied was initially done by unifactorial analysis, followed by multifactorial analysis according to two methods: Cox proportional hazards model and recursive partitioning amalgamation--RECPAM. Regardless of the method used, the main determinants of survival were found to be performance status (Zubrod), weight loss and serum albumin. Other factors such as the staging (presence or absence of metastasis), lymphocytes, lactic dehydrogenase, and hoarseness were also significant. It is noteworthy that age and histological type were irrelevant; sex and hoarseness only proved important when integrated within a multifactorial model. The overall prognostic evaluation and therapeutic decision of advanced NSCLC patients could be improved by combining the prognostic value of TNM with that of performance status, weight loss and serum albumin. These prognostic guidelines must be taken into account when designing new clinical trials.

Prospective computer-assisted voice analysis for patients with early stage glottic cancer: a preliminary report of the functional result of laryngeal irradiation.

In January 1987 we began a prospective study aimed at evaluating objective parameters of vocal function for all patients treated with RT for early glottic cancer. All patients underwent vocal analysis using a voice analyzer interfaced with a computer. This allowed for the determination of percent voicing (%V) (normal = presence of phonation = 90-100%V). Other parameters such as breathiness (air turbulence or hoarseness) and strain (vocal cord tension) were also measured. Patients were recorded before RT, weekly during RT, and at set intervals after RT. There have been 25 patients studied. Eighteen (18) are evaluable at 9 months after treatment. All patients were male and ranged from 45-84 years old. Fourteen (14) and T1 lesions and received 66 GY/33 fractions to their larynx and 4 had T2 tumors and received 66-70 Gy/33-35 fractions. To date, all patients are locally controlled. Three distinct patterns of %V changes have been encountered. However, all patients demonstrated normal phonation pattern by 3 months after RT, and this is sustained at 9 months follow-up. In addition, 94% of patients have had significant decrease in breathiness after RT, which objectively documents diminished hoarseness. In 83%, breathiness is normal after RT. Most patients have had increased strain after RT, which documents increased vocal cord tension. However, strain remained within normal limits in 89%. Our preliminary analysis suggests that the majority of patients irradiated for early glottic cancer demonstrate a decrease in breathiness and an increase in strain after RT, and enjoy a resultant voice that has normal phonation maintained at 9 months after RT. Our data also demonstrate three distinct phonation patterns. Further follow-up will allow us to determine the prognostic significance, if any, of these patterns, and to continue to follow objective vocal parameters on larger numbers of patient.

Reconstruction of recurrent laryngeal nerve with involvement by metastatic node in esophageal cancer.

BACKGROUND: Recurrent laryngeal nerve paralysis represents one of the major complications in esophageal cancer surgery, and patients with esophageal cancer sometimes develop recurrent laryngeal nerve paralysis before treatment. We evaluated recurrent laryngeal nerve reconstruction in patients with lymph node metastasis infiltrating the recurrent laryngeal nerve. METHODS: Five patients with preoperative recurrent laryngeal nerve paralysis as a result of involvement of metastasis were enrolled in the present study. Ansa cervicalis-recurrent laryngeal nerve anastomosis in the neck was performed in 4 patients and direct anastomosis of recurrent laryngeal nerve in the mediastinum in 1 patient. RESULTS: Six months after surgery, 3 patients who had undergone ansa cervicalis-recurrent laryngeal nerve anastomosis in the neck displayed good quality of life without hoarseness or aspiration. The patient who underwent direct anastomosis of the recurrent laryngeal nerve in the mediastinum experienced occasional aspiration and hoarseness. The remaining patient displayed poor condition because of recurrent lung tumor, and quality of life was decreased. CONCLUSIONS: If patients with recurrent laryngeal nerve paralysis before treatment can undergo potentially curative resection with lymph node dissection, including the metastatic lymph node infiltrating the recurrent laryngeal nerve, recurrent laryngeal nerve reconstruction should be performed to improve quality of life.

Jugular foramen syndrome caused by choleastatoma.

Unilateral paresis of 9th-11th cranial nerves together is defined as jugular foramen (Vernet's) syndrome. A cholesteatoma case that penetrated into intracranial area after eroding temporal bone and led to jugular foramen syndrome is presented here, since such a case has not been reported in the literature hitherto. A 46-year-old male patient was evaluated for hoarseness. It was learnt from his anamnesis that he had been operated for otitis media nearly 20 years ago. Uvula deviated towards right. Loss of gag reflex was remarkable on the left. Paresis was found on the left vocal cord. There was weakness in rotation of the head to the right. Computerized tomography (CT) scan revealed that the temporal bone lost its integrity and that there was an extra-axial hypodense mass neighboring pontocerebellum. Post-contrast magnetic resonance imaging showed that the mass, which showed thin, regular circular contrasting and which was hypointense in T1-weighted MR and hyperintense in T2-weighted MR, extended to the left jugular foramen. The mass was totally removed with left sub-occipital approach in the treatment. After the treatment, hoarseness, weakness in the rotation movement of the head and loss of gag reflex recovered totally, while deviation in the uvula was permanent. Cholesteatomas can extend to posterior fossa and cause jugular foramen syndrome. Early surgery is important to completely reverse the lost nerve functions in treatment.

Voice quality of prepubescent children with quiescent recurrent respiratory papillomatosis.

OBJECTIVE: The purpose of this study was to assess the long-term impact of recurrent respiratory papillomatosis (RRP) and its treatment on voice quality in prepubescent children. STUDY DESIGN: Case-control study. METHODS: Prepubescent children with RRP in remission for at least 12 [according to MM section] months were asked to participate. Remission was documented by absence of papillomas on fiberoptic flexible laryngoscopy. An age- and sex-matched control was selected for each patient enrolled. Voice was evaluated using the voice-related quality of life (V-RQOL) questionnaire, perceptual evaluations of voice quality by speech-language pathologists using the GRBAS (grade of hoarseness, roughness, breathiness, asthenia, strain) scale, and acoustic analysis (fundamental frequency, maximal phonation time, and relative average perturbation) using the Visi-Pitch II 3300. RESULTS: Medical records of 84 patients were reviewed and 15 met study criteria. Five agreed to participate but one was excluded due to the presence of papillomas. The four study patients and four matched controls were between 9- and 11-years old. On the V-RQOL questionnaire, each control rated V-RQOL as normal (10/50) and the average patient group score was within the normal range (11.5/50). On perceptual evaluations, the patient's voices were more hoarse, breathy, and rough compared to controls'. Acoustic analysis showed that patients' voices had a lower average fundamental frequency (F(0)) (200 Hz compared to 243 Hz for controls) and a higher relative average perturbation (RAP) (1.10 compared to 0.77), although only one patient's voice actually had elevated RAP (2.89), which had a large impact on raising the average score for the patient group. The average maximal phonation times were similar for the two groups (7.8s for patients and 7.4s for controls) but lower than average normal scores reported in the literature. CONCLUSIONS: Although children with RRP do not perceive their voice quality to have a negative impact on V-RQOL, speech-language pathologist evaluations and acoustic measurements show objective differences between the voices of children with quiescent RRP and those of normal, healthy controls.

Pediatric vocal nodules: correlation with perceptual voice analysis.

OBJECTIVE: To present the epidemiology and correlation with perceptual analysis of vocal nodules in pediatric patients. METHODS: Retrospective review of patients seen in a tertiary care pediatric hospital's voice center from 1996 to 2003. Six hundred and forty-six patients were evaluated with videostroboscopic examinations and perceptual analysis of voice characteristics by speech pathologists. Appropriate treatment was based on the pathology identified. RESULTS: Two hundred and fifty-four patients (40%) with an average age of 7.7 years (range 0.1-19.3 years) were identified as having vocal nodules. Of these, 72% were male. Six patients (2%) were under the age of 7 months. Nodules were most commonly found in males, aged 3-10 years old. Evidence of gastro-esophageal reflux disease was found in one-quarter of patients; hyperfunction of the larynx was seen in three-fourths. Hyperfunction of the larynx correlates with the size of vocal nodules. Distortion of the vocal fold mucosal wave was not present. Perceptual analysis revealed positive correlation of the severity of hoarseness, breathiness, straining and aphonia with the size of vocal nodules. CONCLUSION: The epidemiology and correlation with perceptual voice analysis in pediatric patients with vocal nodules is presented. Hyperfunction of the larynx correlates with nodule size, while the presence of reflux disease does not. The severity of hoarseness, breathiness, straining and aphonia correlates with the size of vocal nodules.

A comparison of anesthetic quality in propofol-spinal anesthesia and propofol-fentanyl anesthesia for total knee arthroplasty in elderly patients.

STUDY OBJECTIVE: To compare propofol plus spinal anesthesia during spontaneous ventilation using the Laryngeal Mask Airway and propofol plus fentanyl anesthesia during mechanical ventilation with an endotracheal tube on quality of recovery after anesthesia. DESIGN: Prospective, randomized study. SETTING: Hirosaki National Hospital. PATIENTS: 150 patients (aged > 70 years) undergoing total knee arthroplasty. INTERVENTIONS: Patients were divided randomly into two groups, to receive spontaneous ventilation with a Laryngeal Mask Airway during propofol-spinal anesthesia, or to receive propofol-fentanyl anesthesia with mechanical ventilation via endotracheal tube. MEASUREMENTS: Quality of anesthesia recovery such as nausea, vomiting, headache, pain throat, hoarse voice, back pain, dizziness, feeling comfortable, dreaming, recovery times in recovery of anesthesia, recovery times, postoperative pain, confusion, was assessed. MAIN RESULTS: The frequency of postoperative pain throat, hoarse voice, and nausea was significantly lower in the propofol-spinal anesthesia group than the propofol-fentanyl anesthesia group. The time to extubation, emergence, response to commands, and orientation were significantly faster (p < 0.001) in the propofol-spinal anesthesia group than the propofol-fentanyl anesthesia group. The frequency of postoperative confusion occurring in the propofol-spinal anesthesia group during the first 24 hours was significantly lower than that of the propofol-fentanyl anesthesia group (p = 0.03). CONCLUSIONS: Propofol-spinal anesthesia provided better and faster recovery than did propofol-fentanyl anesthesia for elderly patients undergoing total knee arthroplasty.

Typical GERD symptoms and esophageal pH monitoring are not enough to diagnose pharyngeal reflux.

BACKGROUND: Abnormal pharyngeal reflux of acid (PR) (as measured by pH monitoring) is associated with microaspiration, and is a good predictor of airway symptom response to medical and surgical anti-reflux therapy. However, in clinical practice the link between airway disease and Gastroesophageal reflux disease (GERD) is still based on the presence of typical symptoms (e.g., heartburn) and/or standard esophageal function testing (manometry and 24-pH monitoring). PR is rarely measured directly. We undertook this study to determine if typical symptoms and standard testing could reliably predict the presence of PR. METHODS: The study group consisted of 518 patients with suspected reflux induced airway disease evaluated from December 1998 through January 2002. Each patient completed a standardized symptom questionnaire, underwent esophageal manometry, and 24-h esophageal and pharyngeal pH monitoring. Patients were classified having abnormal pharyngeal reflux (PR+) if they had >1 episode of PR detected during pH monitoring. RESULTS: One hundred eighty-one patients were PR+ and 337 were PR-. The most common symptoms, namely cough (PR +73%, PR- 68%), hoarseness (PR +64%, PR- 66%), and dyspnea (PR +59%, PR- 59%) were present with similar incidence in PR+ and PR- patients. The incidence of heartburn was 54% in the PR+ and 52% in the PR- patients. Logistic regression analysis revealed that abnormal esophageal acid exposure was a predictor of PR+ (P < 0.001). Neither the presence of heartburn or specific respiratory symptoms, the pressure of the lower esophageal sphincter (LES) or upper esophageal sphincter (UES), or amplitude of esophageal contractions predicted PR+. There was substantial variability in esophageal length (UES to LES), thus the placement of the distal pH probe from the LES varied considerably (median = 13 cm, 2-20 cm). Using established normal values of acid exposure at multiple levels of the esophagus, 24% of PR+ patients had normal amounts of esophageal acid exposure. CONCLUSIONS: Typical GERD symptoms, such as heartburn, and typical symptoms of aspiration such as hoarseness, cough, or dyspnea are not enough to positively identify PR. While patients with abnormal esophageal acid exposure are three times more likely than those with normal values to have PR, abnormal esophageal acid exposure alone does not identify all patients with PR. Therefore, relying on symptoms and standard diagnostic testing may fail to identify patients with extraesophageal reflux. Pharyngeal pH monitoring should be considered for patients with suspected reflux-induced airway disease.

Prevalence of voice disorders in African American and European American preschoolers.

Several studies have reported prevalence rates for voice disorders in school-aged children. Less is known, however, about such prevalence in preschoolers, and whether racial, ethnic, or cultural diversity may influence it. The presence of voice disorders in a total of 2445 African-American and European-American preschool children, 1246 males and 1199 females, from 2 to 6 years of age is reported here. Presence of a voice disorder characterized by hoarseness was identified by a three-prong approach including teacher identification, investigator screening, and parent identification. Speech-language pathologists listened individually to each child's speech as they engaged each child in play-conversation activities. A voice disorder was identified on the basis of the judgment of two speech-language pathologists. Voice disorders characterized by hoarseness were identified in 95 children or 3.9% of the total sample by the investigators. Statistical analysis revealed no significant differences for age, gender, or race.

Acoustic prediction of voice type in women with functional dysphonia.

The categorization of voice into quality type (ie, normal, breathy, hoarse, rough) is often a traditional part of the voice diagnostic. The goal of this study was to assess the contributions of various time and spectral-based acoustic measures to the categorization of voice type for a diverse sample of voices collected from both functionally dysphonic (breathy, hoarse, and rough) (n=83) and normal women (n=51). Before acoustic analyses, 12 judges rated all voice samples for voice quality type. Discriminant analysis, using the modal rating of voice type as the dependent variable, produced a 5-variable model (comprising time and spectral-based measures) that correctly classified voice type with 79.9% accuracy (74.6% classification accuracy on cross-validation). Voice type classification was achieved based on two significant discriminant functions, interpreted as reflecting measures related to "Phonatory Instability" and "F(0) Characteristics." A cepstrum-based measure (CPP/EXP ratio) consistently emerged as a significant factor in predicting voice type; however, variables such as shimmer (RMS dB) and a measure of low- vs. high-frequency spectral energy (the Discrete Fourier Transformation ratio) also added substantially to the accurate profiling and prediction of voice type. The results are interpreted and discussed with respect to the key acoustic characteristics that contributed to the identification of specific voice types, and the value of identifying a subset of time and spectral-based acoustic measures that appear sensitive to a perceptually diverse set of dysphonic voices.

Current and emerging concepts in muscle tension dysphonia: a 30-month review.

UNLABELLED: The modern theory of hoarseness is that there are multifactorial etiologies contributing to the voice problem. The hypothesis of this study is that muscle tension dysphonia is multifactorial with various contributing etiologies. METHODS: This project is a retrospective chart review of all patients seen in the Voice Speech and Language Service and Swallowing Center at our institution with a diagnosis of muscle tension (functional hypertensive) dysphonia over a 30-month period. A literature search and review is also performed regarding current and emerging concepts of muscle tension dysphonia. RESULTS: One hundred fifty subjects were identified (60% female, 40% male, with a mean age of 42.3 years). Significant factors in patient history believed to contribute to abnormal voice production were gastroesophageal reflux in 49%, high stress levels in 18%, excessive amounts of voice use in 63%, and excessive loudness demands on voice use in 23%. Otolaryngologic evaluation was performed in 82% of patients, in whom lesions, significant vocal fold edema, or paralysis/paresis was identified in 52.3%. Speech pathology assessment revealed poor breath support, inappropriately low pitch, and visible cervical neck tension in the majority of patients. Inappropriate intensity was observed in 23.3% of patients. This set of multiple contributing factors is discussed in the context of current and emerging understanding of muscle tension dysphonia. CONCLUSIONS: Results confirm multifactorial etiologies contributing to hoarseness in the patients identified with muscle tension dysphonia. An interdisciplinary approach to treating all contributing factors portends the best prognosis.

Awareness of general practitioners towards treatment of laryngopharyngeal reflux: a British survey.

OBJECTIVE: Patients with acid reflux can occasionally present with atypical symptoms such as globus pharyngeus, constant throat clearing, chronic cough, hoarseness, catarrh, choking episodes or asthma-like symptoms. The aim of this survey was to determine whether general practitioners are aware of the atypical manifestations of reflux and the differences in treatment between laryngopharyngeal reflux and gastroesophageal reflux. DESIGN: Questionnaire Survey. SETTING: Primary Care RESULTS: One hundred and sixty general practitioners who routinely refer patients to our Department of Otolaryngology were selected and a postal survey was conducted. One hundred and fifty of these responded (94% response rate). The commonest symptoms for which proton pump inhibitors are prescribed are heartburn (65%), followed by a combination of heartburn and other symptoms (15%), chronic cough (4%), choking episodes (4%), asthma-like symptoms (3%), hoarseness (2%), globus (2%), catarrh (1%), dysphagia (1.5%), frequent throat clearing (1.5%), halitosis and/or bitter taste (1%). CONCLUSIONS: Our results suggest that the majority of the general practitioners surveyed are unaware of the entity laryngopharyngeal reflux or reflux symptom index. More awareness is required in the primary care setting for early recognition of patients with suspected laryngopharyngeal reflux.
