Head and neck cancer screening among 4611 tobacco users older than forty years.

We implemented screening for squamous cell carcinomas of the oral cavity, pharynx, and larynx with symptom assessment and systematic inspection of the oral mucosa by primary care practitioners at health care sites serving inner-city residents of Boston; 4611 tobacco users older than 40 years were screened, and 313 with specific criteria were referred to otolaryngology for diagnostic evaluations. In these screened patients, the prevalence of oral mucosal lesions was almost 13% and prevalence of persistent hoarseness was more than 11%. Although the identification of these cancers was rare (nearly 3%), abnormal findings were seen in more than 70% of referred patients. These clinical and histologic diagnoses are described. We have documented the range of pathologic conditions in high-risk patients screened for upper aerodigestive tract malignancy.

Upper airway dysfunction--an unusual presentation of Guillain-Barré syndrome.

We report the case of a 9-year-old boy who presented to the emergency department with dysphagia, respiratory distress, hoarseness, and generalized weakness. While in the ED, his respiratory status deteriorated, and he required intubation. At that time, he was found to have normal upper airway anatomy. He was admitted to the pediatric ICU and, within 24 hours, developed areflexia and muscle weakness; he was diagnosed with Guillain-Barré syndrome. Atypical presentations of Guillain-Barré syndrome are discussed, and the necessity of considering this diagnosis when evaluating patients with evidence of cranial nerve dysfunction or upper airway distress is emphasized.

Inhalation of products of combustion.

The atmosphere of a fire is deadly to breathe. Firefighters or building occupants may be victims of the heat, irritating smoke, depleted oxygen, carbon monoxide, and such other toxic gases as cyanide, hydrogen chloride, and acrolein. Increasing numbers of homes and public buildings are being built and furnished with highly flammable synthetic materials that give off copious smoke and toxic gases when burned. Whether or not there are cutaneous burns, the possibility of inhalation injury must be considered in any fire victim. All victims of a fire environment should be presumed to have CO intoxication and should be treated with 100% oxygen until the HbCO level is within normal limits. In an extreme situation, cyanide intoxication should be suspected and administration of sodium thiosulfate may be lifesaving. Upper airway occlusion may result from thermal damage or edema secondary to burns from soluble toxic gases. Chemical injury to the lower airway and alveoli may result from inhalation of insoluble irritant gases and toxic gases adsorbed on carbon particles. Upper respiratory tract obstruction may be suggested by the clinical presentation (eg, pharyngeal burns, stridor, hoarseness, dysphagia), but only by means of fiberoptic bronchoscopy can it be recognized or excluded with certainty. Intubation may be necessary. Lower respiratory tract injury may be manifest clinically by dyspneas, wheezing and chest tightness, as well as by hypoxemia and reduced FEV1 and FVC. Treatment is symptomatic, but close observation for progressive respiratory insufficiency is necessary.

Blunt laryngeal trauma associated with shoulder harness use.

A case of blunt laryngeal trauma secondary to use of a shoulder harness is presented. The patient, restrained with a lap and shoulder belt, was the occupant of an automobile involved in a rear-end collision. She presented with left anterior neck pain and two hours later developed hoarseness and hemoptysis. A laryngeal laceration, identified by laryngoscopy, was surgically repaired after tracheostomy. The patient had an uncomplicated hospital course and uneventful recovery.

Penetrating injuries of the visceral compartment of the neck.

Penetrating injuries of the visceral compartment of the neck are uncommon but potentially life threatening. A retrospective review of patients who sustained penetrating trauma to the laryngotracheal complex was conducted at the Level I trauma center of the University of Louisville Hospital in Kentucky. Sixteen patients were identified and their records reviewed for type of injuries, treatment, complications, and 1-year follow-up. The majority of patients were men who sustained injuries that were violent in nature. Zone II of the anterior neck was the most commonly injured area, with the trachea (69%), esophagus (38%), and larynx (31 %) the most commonly injured structures. Although 31% underwent angiograms, only 13% showed vascular injuries. Eighty-one percent of the patients had injuries involving more than 1 major structure of the neck. Neck exploration was performed in 81% of the patients and tracheotomies in 75% as well as repair of the trachea (50%), larynx (31%), and esophagus (38%). There is significant mortality associated with these injuries (13% in our study), and many of the patients have long-term sequelae such as dysphagia, hoarseness, and prolonged tracheotomy.

Removal of a laryngeal leech: A safe and effective method.

This article presents a case of hoarseness, dysphagia, and hemoptysis caused by the laryngeal localization of a leech. This pathological condition is extremely rare in urban areas but is frequent in endemic rural areas. Laryngoscopic evaluation of our patient has shown a leech lodged on the left arytenoid region hanging down to larynx. We present a patient living in an urban area with laryngeal leech that was removed under general induction anesthesia of sevoflurane via a face mask without endotracheal intubation.

Neurologic disorders: amyotrophic lateral sclerosis, myasthenia gravis, multiple sclerosis, and poliomyelitis.

The patient who has multiple cranial neuropathies may pose a diagnostic dilemma. The neurologic disorders of amyotrophic lateral sclerosis, multiple sclerosis, myasthenia gravis, and poliomyelitis often cause bulbar dysfunctions such as diplopia, facial weakness, slurred or hypernasal speech, dysphagia, and hoarseness. In general, treatment is supportive and is directed toward restoring or aiding lost function (i.e., tracheostomy, esophagostomy, and cricopharyngeal myotomy). The relative infrequency of these disorders can lead to delays in diagnosis and rehabilitative therapy.

Aspiration in unilateral recurrent laryngeal nerve paralysis after surgery.

PURPOSE: Dysphonia with hoarseness and breathiness are the key symptoms of unilateral recurrent laryngeal nerve (RLN) paralysis, whereas aspiration is not usually described. The aim of this prospective study was to assess the incidence of aspiration in patients with unilateral recurrent laryngeal nerve paralysis after head and neck or thoracic surgery. PATIENTS AND METHODS: Five patients were included and evaluated within the first week and again 2 months postoperatively. Position, tone, and tension of the true vocal cord as well as assessment of the glottic axis, arytenoid position, laryngeal sensation, status of the pyriform sinus, and salivary stasis were studied. Swallowing evaluation was performed using flexible fiberoptic laryngoscopy during dry swallowing, thick cream, methylene blue liquid as well as with swallowing videofluoroscopy. RESULTS: Three patients had no aspiration, one patient had silent aspiration, and one had symptomatic aspiration. CONCLUSION: We conclude that aspiration may occur in unilateral recurrent laryngeal nerve paralysis and have to be systematically evaluated after pneumonectomy.

Delayed radionecrosis of the larynx.

Radiation has been used to treat carcinoma of the larynx for more than 70 years. Radionecrosis is a well-known complication of this modality when treating head and neck neoplasms. It has been described in the temporal bone, midface, mandible, and larynx. Laryngeal radionecrosis is manifested clinically by dysphagia, odynophagia, respiratory obstruction, hoarseness, and recurrent aspiration. The vast majority of patients who develop laryngeal radionecrosis present with these symptoms within 1 year of treatment; however, delayed presentations have been reported up to 25 years after radiotherapy. We present, in a retrospective case analysis, an unusual case of laryngeal radionecrosis in a patient who presented more than 50 years after treatment with radiotherapy for carcinoma of the larynx. The cases of delayed laryngeal necrosis in the literature are presented. This represents the longest interval between treatment and presentation in the literature. The details of the presentation, clinical course, and diagnostic imaging are discussed. The pathogenesis, clinical features, and treatment options for this rare complication are reviewed. Early stage (Chandler I and II) laryngeal radionecrosis may be treated conservatively and often observed. Late stage (Chandler III and IV) cases are medical emergencies, occasionally resulting in significant morbidity or mortality. Aggressive diagnostic and treatment measures must be implemented in these cases to improve outcome. This case represents the longest interval between initial treatment and presentation of osteoradionecrosis in the literature. A structured diagnostic and therapeutic approach is essential in managing this difficult problem.

Otolaryngologic complications of the anterior approach to the cervical spine.

PURPOSE: To review current literature regarding otolaryngologic complications of the anterior approach to the cervical spine with the focus on the etiology, diagnosis, and treatment of these disorders. METHODS: A review of literature from the introduction of anterior cervical surgery (late 1950s) to the present was conducted by using computer databases and bibliographies of appropriate journal articles and texts. Key words included "anterior cervical surgery," "dysphagia," "surgical complications," and "hoarseness." CONCLUSION: Dysphagia and dysphonia are common conditions following anterior cervical fusion, and patients should be counseled on this risk preoperatively. The etiologies of these problems have not been clearly elucidated, and these complications are frequently underreported or ignored. Otolaryngologic consultation should be obtained for all patients with dysphagia or dysphonia that persists longer than 1 to 2 months, and consideration should be given to having all patients at risk (previously operated patients) evaluated both preoperatively and postoperatively.

Chondroid tumors of the larynx: computed tomography findings.

PURPOSE: Chondromas and chondrosarcomas of the larynx are rare cartilaginous tumors making up less than 1% of all laryngeal tumors. Patients typically present with symptoms of hoarseness, dysphagia, or dyspnea. The most common location in the larynx for these tumors is the cricoid cartilage. Radiographically, these lesions are typically hypodense, well-circumscribed masses containing mottled calcifications with smooth walls centered within the cartilage. MATERIALS AND METHODS: We present 6 cases of chondroid tumors of the larynx. RESULTS: One patient had a chondroma, 4 patients had low-grade chondrosarcomas, and 1 patient had an intermediate-grade chondrosarcoma. Two partial laryngeal resections and 4 total laryngectomies were performed. CONCLUSIONS: In most cases of chondroma or chondrosarcoma of the larynx, conservative surgery should be attempted, but total laryngectomy may be required for large or recurrent lesions.

[Specific respiratory manifestations of Horton disease].

Several respiratory manifestations have been described in patients with temporal arteritis. These complications may develop at the onset of the disease or later. Cough is the most frequent of them. Other complications include pleural effusions, interstitial pneumonitis, pulmonary vasculitis. Hyperreactive airways, hoarseness, diaphragm paralysis have been noted. Generally, corticosteroids cause a prompt improvement. Physicians should be aware of respiratory symptoms in patients with temporal arteritis in order to avoid delays in diagnosis and therapy.

[Isolated laryngeal candidiasis. Description of 2 cases and review of the literature].

Infection of the larynx by Candida is rare and usually accompanies lung or disseminated candidiasis. The incidence of isolated laryngeal candidiasis (ILC) is low, although it may be underestimated. We describe 2 patients with ILC confirmed during autopsy: a 45-years-old male with pulmonary fibrosis and a 4-years-old girl with acute myeloblastic leukemia. Hoarseness and dysphagia are the most common symptoms of ILC. The most effective diagnostic technique is laryngoscopy with specimen culture and/or histopathology. Specimens usually show whitish plaques on the larynx. Most ILC patients have some associated disease and/or predisposing factors, with frequent antibiotic treatment prior to the advent of candidiasis. Intravenous amphotericin B provides the most effective therapy, although other antimycotics are also useful. Early diagnosis and initiation of therapy curtail the disease and can prevent systemic dissemination.

Vagus nerve stimulation for treatment of medically intractable seizures. Evaluation of long-term outcome.

UNLABELLED: Vagus nerve stimulation (VNS) constitutes an adjunctive, modern management of medically intractable seizures, especially when surgery is inadvisable. OBJECTIVE: To evaluate the long-term results as regards efficacy, safety and tolerability of VNS in epileptic subjects, with focal and/or generalised seizures, refractory to old and new AEDs, without indication for resective surgery. PATIENTS: 51 epileptic subjects (30 males, 21 females), aged 7-49 years, have been implanted so far. RESULTS: The results refer to the 47 subjects with a follow-up longer than 6 months. 22 (46.8%) of them had a greater than 50% reduction in seizure frequency, with a more than 75% reduction in 6. No significant difference was found in relation to type of seizures. The efficacy maintained steadily over time during the follow-up (mean 26.4 months). Twelve out of the 47 subjects had an improvement in alertness, attention and psychomotor activity. Complications were observed in 5 cases, leading to removal of the stimulator in 2. A moderate vocal hoarseness (40.4%), paresthesia (6.3%), pharingodinia and cough (4.3%) were the registered adverse events. CONCLUSIONS: Our results confirm that VNS is effective, safe and well tolerated and constitutes an alternative treatment for pharmacoresistant epileptic seizures.

Clinicopathologic study and classification of vocal cord cysts.

Cysts of the true vocal cords are less common than other laryngeal cysts. They are usually easily recognized and managed. Patients present with complaints of hoarseness and/or dyspnea. We report our experience with 41 cases of cysts located in the true vocal cords. Clinical and histological aspects are reviewed and discussed. A new histological classification is proposed: A: cysts lined by columnar epithelium with mucous content; B: lined by columnar epithelium with cilia; C: lined b squamous epithelium without keratinization; D: lined by squamous epithelium with keratinization.

Involvement of the larynx by hemopoietic neoplasms. An investigation of autopsy cases and review of the literature.

Involvement of the larynx by hemopoietic tumors is generally considered a rare event and little is known about the associated clinicopathologic features. Laryngeal tissue removed at autopsy from 14 patients with known disseminated hematologic malignancies and at operation from one patient with multicentric malignant lymphoma of low-grade malignancy (MALToma) of the head and neck region was investigated. A systematic survey of the main clinicopathologic features of the published cases of hemopoietic tumors with laryngeal involvement was also performed. Primary involvement of the larynx by hemopoietic neoplasms must be clearly distinguished from secondary involvement by disseminated or leukemic tumors. Most of the primary tumors are localized lesions that may involve the regional lymph nodes (stages IE or IIE). Radiotherapy is the treatment of choice, and the prognosis is generally favorable. However, secondary involvement by disseminated or leukemic disease carries a very poor prognosis in most cases. Extramedullary plasmacytoma and non-Hodgkin's lymphoma (NHL), particularly B-cell lymphoma of high-grade malignancy, appear to be the most common hemopoietic tumors with primary laryngeal involvement, while primary tumors of myelogenous origin (granulocytic sarcoma and mast cell sarcoma) are extremely rare. Extramedullary plasmacytoma and NHL occur mainly in older persons and in men, are generally associated with a relatively short history of hoarseness and dysphagia, and exhibit preferential involvement of the supraglottic parts of the larynx, in particular the epiglottis and aryepiglottic folds. They are generally polypoid, non-ulcerated lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

Recursive partitioning analysis of 1999 Radiation Therapy Oncology Group (RTOG) patients with locally-advanced non-small-cell lung cancer (LA-NSCLC): identification of five groups with different survival.

PURPOSE: Survival of patients with locally-advanced non-small-cell lung cancer (LA-NSCLC) is predicted by the stage of the disease and other characteristics. This analysis was undertaken to identify these characteristics in a large cooperative group patient population, as well as to define subgroups of the population with differing outcomes. PATIENTS AND METHODS: Analysis included 1,999 patients treated in 9 RTOG trials between 1983 and 1994 with thoracic irradiation (RT) with (n = 355) or without chemotherapy (CT). RESULTS: In univariate analysis, the following characteristics were significantly associated with an improved survival: use of CT, CT delivered without major deviation, abnormal pulmonary function tests, normal hemoglobin, protein, LDH and BUN, presence of dyspnea, hemoptysis, cough or hoarseness, uninvolved lymph nodes, T1 or T2 stage, no malignant pleural effusion (PE), weight loss of < 8%, Karnofsky performance status (KPS) of at least 90, adenocarcinoma histology, female gender, and age less than 70 years. Recursive partitioning analysis (RPA) was subsequently applied to identify 5 patient subgroups with significantly different median survival times (MST): Group I, KPS of > or = 90, who received chemotherapy (MST 16.2 months); Group II, KPS of > or = 90, who received no CT, but had no PE (MST 11.9 months); Group III, KPS < 90, younger than 70 years, with non-large cell histology (MST 9.6 months); Group IV, KPS > or = 90, but with PE, or KPS < 90, younger than 70 years, and with large cell histology, or older than 70 years, but without PE (MST 5.6-6.4 months); Group V, older than 70, with PE (MST 2.9 months). CONCLUSION: Cisplatinum-based CT improves survival, for excellent prognosis of LA-NSCLC patients, over RT alone. The presence of a malignant pleural effusion is a major negative prognostic factor for survival. The identification of RPA prognostic groups among patients with LA-NSCLC provides prognostic information and may serve as a basis of stratification in future trials.
