Lipoid proteinosis of the larynx.

Lipoid proteinosis is a rare disease that presents with hyaline deposits in many tissues. It involves predominantly the skin and upper aerodigestive tract, presenting with small yellowish papules and hoarseness. It may involve the central nervous system and cause intracerebral calcifications. Laryngeal lesions may resemble singer's nodule or chronic laryngitis. The pathogenesis of the disease is not clear although several studies suggest a defective collagen production and/or lysosomal storage disease. In this article two cases with skin and larynx involvement are reported.

Dual-probe 24-hour ambulatory pH monitoring for diagnosis of laryngopharyngeal reflux.

BACKGROUND: Patients with gastroesophageal reflux disease may suffer from a variety of symptoms from the upper aerodigestive tract. The objective of this study was to determine the impact of dual-probe 24-hr pH monitoring in the diagnosis of reflux-related otolaryngological disorders. METHODS: Twenty-two patients with symptoms such as chronic cough, globus pharyngeus, heartburn, dysphonia and burning sensation of the tongue underwent a complete ear, nose and throat examination, 24-hr dual-probe pH monitoring, and oesophago-gastro-duodenoscopy. RESULTS: pH monitoring revealed gastroesophageal (distal) reflux in all patients and pharyngeal (proximal) reflux in 21 patients. Treatment consisted of a proton pump inhibitor (esomeprazole). Within 4 weeks 68 per cent of patients had no laryngopharyngeal symptoms; within 8 weeks 95 per cent of patients were symptom-free. CONCLUSIONS: Patients with atypical reflux symptoms such as hoarseness, globus sensation or throat-clearing responded well to anti-reflux treatment.

Laryngeal tuberculosis: review of twenty cases.

Despite a dramatic reduction in incidence of laryngeal tuberculosis over the last three decades, tuberculous involvement still has to be considered in the differential diagnosis of laryngeal lesions. The majority of the 20 cases in our series consists of patients in whom the working diagnosis of carcinoma of the larynx was initially made. These patients presented with the chief complaint of hoarseness of several months duration, frequently associated with dysphagia, but in most cases with chest symptoms that were not prominent despite the fact that most of these patients had far advanced pulmonary tuberculosis. This presentation consists of a detailed analysis of 20 cases, and a discussion of the incidence, pathogenesis, clinical presentation and management of laryngeal tuberculosis.

Osteochondroma presenting as a neck mass: a case report.

Osteochondromas are benign bone tumors which rarely present as neck masses. This report reviews the literature and presents the case of a 10-year-old girl with a neck mass and hoarseness due to an osteochondroma of the cervical spine. An extensive diagnostic evaluation and partial surgical excision were necessary. Although rare, osteochondromas should be considered in the differential diagnosis of a firm neck mass. Surgical excision of these lesions is recommended.

Phonatory characteristics following surgical treatment of severe polypoid degeneration.

This paper summarizes the results of our research into the efficacy of phonosurgery. Our study group consisted of 25 women whose severe, bilateral polypoid degeneration was managed surgically by one of the following methods: Hirano's technique, mechanical stripping, or CO2 laser enucleation. We found that all three procedures improved the voice. Surgery increased the average speaking fundamental frequency level substantially and improved the phonational range. Listeners' judgments about the appropriateness of vocal pitch and severity of hoarseness also changed positively following surgery. No one method was clearly better than another in improving the voice. However, patients treated using Hirano's method experienced the most rapid return of functional voice use, probably because the procedure is less traumatic and promotes more rapid healing than mechanical stripping or laser removal.

H-Index: a new measure of glottal efficiency for the pathologic voice.

Taking advantage of the extended dynamic range of digital analysis of voice the H-Index represents the first proposed acoustical measure of glottal efficiency. "Hi" /hai/ was chosen to evaluate glottal efficiency since it provides an excellent test of glottal transformation from voiceless to voiced sound energy, the upper vocal tract having a neutral effect. Fifteen individuals with normal voices and 30 patients with hoarse voices were asked to say "hi." The power ratio of /h/ to /a/ was calculated from peak power of each measure from the power envelope. Voice quality had a highly significant effect on measured values (P < .001). A high degree of correlation (P < .001) was found with the AC/DC ratio, a standard aerodynamic measure of glottal efficiency. The results indicate that the H-Index represents an excellent measure of glottal efficiency, obviating the need of invasive techniques or expensive, highly specialized equipment.

Anterior commissure microwebs associated with vocal nodules: detection, prevalence, and significance.

Vocal fold nodules are a common cause of dysphonia generally attributed to vocal abuse. Anterior commissure microwebs have been reported as an incidental finding in surgical patients with nodules. In a series of 105 nodule patients evaluated at the University of Wisconsin Clinical Science Center voice laboratory (1987-1992), 11 microwebs were identified. Ten of these microweb patients were among the 20 nodule patients who did not respond to voice therapy and underwent microsurgery. In patients with nodules whose hoarseness is refractory to voice therapy, symptoms that occur early in life suggest the presence of occult vocal fold pathology. Microweb detection requires a high index of suspicion, observation during maximal vocal fold abduction, and clearance of secretions from the anterior commissure. Definitive identification is facilitated by gentle separation of the anterior vocal folds during direct microlaryngoscopy. The presence of these tiny shelves of tissue might be coincidental, or they might represent another expression of the tissue response to traumatic factors known to produce vocal nodules. We found little difference in vocal function parameters between two similar groups of nodule patients, one with and one without associated microwebs. Further work is needed to determine the significance of microwebs.

[Health condition of female aerobic dance instructors. Subjective symptoms and related factors].

Aerobic dance has recently become popular in all age groups, but the injuries among full-time and part-time aerobic dance instructors have rarely been pointed out in Japan. In this study the subjective symptoms of 63 female instructors in Gifu area were evaluated through health questionnaire. As a control group, 94 female students of the same age group were also included to compare the prevalence of subjective symptoms. Multiple logistic regression analysis was applied to observe the relation between instructors' symptoms and working conditions. The following results were obtained: 1) Complaints of leg and foot pain and laryngeal discomfort were significantly greater in instructors than in students even after adjusting for age and participation in other sports. 2) A significant positive relation was found in instructors between the frequency of dance lessons (times/wk) and various symptoms (calf pain, foot pain, sore throat, and hoarse voice) after adjusting for age and participation in other sports. These results suggest that leg and foot pain and laryngeal discomfort are characteristic symptoms of aerobic dance instructors. Consideration should be made to adjust the frequency of dance lessons in order to reduce these symptoms.

[Prevalence of voice alteration among educators and its relationship with self-perception].

OBJECTIVE: To verify the prevalence of self-reported voice alteration among educators in crèches, and associated factors. METHODS: This was a cross-sectional observational study carried out in 2001, in eight crèches in the city of São Paulo at which actions within the Crèche Program were being developed. This program formed part of the health promotion activities of a speech therapy investigation laboratory. The data collection was done by means of a questionnaire that was filled out by 93 educators, with questions on sociodemographic characteristics, aspects of the organization and physical environment of the work, habitual voice utilization, history of illnesses, lifestyle and perceptions regarding voice alterations. Assessment of hearing perception was done on the participants' voices. The statistical analysis utilized proportions, central trend measurements, Chi-square test with Yates correction and multiple logistic regression analysis. RESULTS: Eighty percent of the educators reported that they had voice alterations, although only 26% had sought treatment. A large proportion (39%) reported that they had had their problem for four years or more, that it was intermittent (82%) and that they had it to a slight or moderate degree (74%). They believed that the main cause of voice alteration was their use of their voices (82%), and their principal symptom was hoarseness (54%). Self-reported voice alteration was statistically associated with presence of voice alteration observed during assessment and with having had some guidance on voice usage. CONCLUSIONS: Adequate perception among educators regarding their voice problems could become an important tool for future work among this population with a view to diminishing the high prevalence of voice alteration encountered.

Amyloidosis of the larynx.

Amyloidosis of the larynx is a rare disease, accounting for less than 1% of all benign laryngeal 'tumours'. Three cases of this type of lesion are reported--one of the vocal cord, one of the false vocal cord and one of the subglottis and trachea. In 2 of the patients the amyloidosis was localized, while the third was later found also to have an epipharyngeal solitary plasmacytoma with amyloid deposits and in addition amyloidosis of the nasal cavity. However, the amyloidosis in this patient may still be regarded as being localized, as the clinical examination and laboratory tests afforded no evidence of generalized disease. Amyloidosis of the larynx may be manifested as a localized tumour or as a diffuse infiltration. The symptoms and signs will, of course, depend on the site of the amyloid deposit. When the vocal cords are involved hoarseness may result, and this was the most prominent sign in the present cases. The treatment of laryngeal amyloidosis is primarily by endoscopic excision. Amyloid substance has specific staining properties. The Congo red reaction with a green birefringence in polarized light and Phorwhite BBU using fluorescence microscopy are regarded as the most reliable staining reactions. Electron microscopy has revealed a typical fibrillar structure of amyloid.

Dysplastic collagen fibrils in the human vocal fold. An electron microscope study.

Electron microscope studies made on biopsy samples of the human vocal cord from patients suffering from chronic hoarseness revealed pathological changes in both the collagen fibrils and the elastic fibres. There was splitting and fracturing of the collagen fibrils and lacuna or cyst formation in the elastic fibres, or even the complete fibre degeneration. Further investigations must be undertaken in order to establish whether the changes observed are of a primary or secondary nature.

Retrotracheal thymoma masquerading as esophageal submucosal tumor.

A 42-year-old man presented with a two-year history of progressive dysphagia and hoarseness. Esophagogram and endoscopy revealed submucosal mass effect on the upper esophagus. Computed tomography and magnetic resonance imaging revealed an elongated mass in the retrotracheal region of the lower neck with extension to the posterior mediastinum. Partial tumor resection and histopathological evaluation revealed a WHO type B2 thymoma. Adjuvant radiation and chemotherapy were subsequently administered resulting in complete tumor regression. To our knowledge, this is the first report of ectopic retrotracheal thymoma with clinical and imaging manifestations mimicking those for esophageal submucosal tumor.

Primary malignant melanoma of the larynx.

Primary malignant melanoma of the larynx is a rare clinical entity. Only 53 cases have been reported in the medical literature to date. This report describes a case of primary malignant melanoma arising in the larynx and diagnosed by histologic examination of an excisional biopsy specimen. The patient was a 53-year-old man with a history of smoking and hoarseness. There was no clinical evidence of other primary malignant melanocytic lesions. Microscopically, the tumor consisted of polygonal-epithelioid cells admixed with more elongated, spindle-shaped cells. The majority of the cells demonstrated dark brown cytoplasmic and nuclear melanin. Marked pleomorphism and abnormal mitoses were also identified. Despite significant ulceration and disruption of the epithelium, in situ malignant melanocytes were recognized within the remaining portion of the epithelium. Immunohistochemical studies were positive for S100, HMB-45, and vimentin, while cytokeratin and iron stains were negative. Based on the clinical and histologic findings, a diagnosis of primary malignant melanoma of the larynx was established.

Respiratory tract symptoms as a clue to giant cell arteritis.

Although many manifestations of giant cell arteries are increasingly recognized, little attention has been paid to respiratory symptoms associated with this disorder. We report the cases of 16 patients with giant cell arteritis who had prominent symptoms related to the respiratory tract including cough, sore throat, and hoarseness. These symptoms were the initial finding in 10 patients and obscured the diagnosis in some instances, but resolved quickly when corticosteroids were given. It is estimated that 9% of patients with giant cell arteritis have prominent respiratory tract symptoms, which are the initial manifestation in 4%. This disorder should be considered in an older patient with a new cough or throat pain without obvious cause.

[Intermediate syndrome after acute organophosphorus pesticides poisoning: clinical analysis of 10 cases].

Ten patients with intermediate syndrome (IMS) after acute organophosphorus (OP) pesticides poisoning were observed. The occurrence rate of IMS was 5.4% among total inpatients of acute OP poisoning in the same period. The majority of IMS cases were of severe oral OP poisoning. Seven to 68 hours after poisoning there were initial signs including motor weakness of muscles innervated by the 9th and 10th cranial nerves (e.g. dysphagia, hoarse voice). The neck flexor muscles and proximal limb muscles were also involved. Patients with respiratory muscle paralysis usually required urgent tracheal intubation and mechanical ventilation. The IMS in this group persisted for 6-30 days (mean 13 days) with no fatality. The relevant kinds of pesticide, the development and regression of IMS, and the treatment and possible mechanism of IMS were discussed.

Preservation of the recurrent laryngeal nerves in thyroid and parathyroid reoperations.

BACKGROUND: The recurrent laryngeal nerve (RLN) is vulnerable to injury in thyroid and parathyroid reoperations because of the presence of scar tissue and displacement of the nerve from its normal position. METHODS: Since 1993, we have performed 132 reoperations for recurrence of thyroid or parathyroid carcinoma (102 cases), persistent hyperparathyroidism (21 cases), and recurrent goiter (9 cases). One or both RLNs were identified in all cases (208 nerves). Exposure of the nerve was accomplished by a lateral approach (159 nerves), a low anterior approach (41 nerves), or the identification of the nerve between the larynx and the upper pole of the thyroid, in parathyroid reoperations (8 nerves). Dissection was then done while the nerve was kept in view at all times. RESULTS: Preoperatively, unilateral vocal cord paralysis was noted in 6 patients. Resection of a functioning RLN encased with a tumor was intentionally carried out in 5 patients. The RLNs were identified and preserved in all other cases. Among these 121 patients, transient hoarseness lasting up to a month occurred in 12 patients. CONCLUSIONS: Careful identification and exposure of the RLN through a previously undissected area can be done safely in thyroid and parathyroid reoperations and resulted in no permanent recurrent nerve injuries in our experience.
