1/221. mucoepidermoid tumor of trachea.

    Mucoepidermoid carcinoma of the trachea is rare. Its occurence in a 14-year-old boy is reported here. This case illustrates the typical course of tracheal tumors with clinical manifestations of cough, wheezing, and hemoptysis, the intially reported normal chest roentgenogram, and the common failure to diagnose tracheal tumor for several months. Early use of tomographic studies and bronchoscopic examination in any person with recent onset of airway obstruction unresponsive to bronchodilator therapy is recommended.

2/221. Pseudo-steroid resistant asthma.

    BACKGROUND: Steroid resistant asthma (SRA) represents a small subgroup of those patients who have asthma and who are difficult to manage. Two patients with apparent SRA are described, and 12 additional cases who were admitted to the same hospital are reviewed. methods: The subjects were selected from a tertiary hospital setting by review of all asthma patients admitted over a two year period. Subjects were defined as those who failed to respond to high doses of bronchodilators and oral glucocorticosteroids, as judged by subjective assessment, audible wheeze on examination, and serial peak flow measurements. RESULTS: In 11 of the 14 patients identified there was little to substantiate the diagnosis of severe or steroid resistant asthma apart from symptoms and upper respiratory wheeze. Useful tests to differentiate this group of patients from those with severe asthma appear to be: the inability to perform reproducible forced expiratory manoeuvres, normal airway resistance, and a concentration of histamine causing a 20% fall in the forced expiratory volume (FEV1) being within the range for normal subjects (PC20). Of the 14 subjects, four were health care staff and two reported childhood sexual abuse. CONCLUSION: Such patients are important to identify as they require supportive treatment which should not consist of high doses of glucocorticosteroids and beta2 adrenergic agonists. Diagnoses other than asthma, such as gastro-oesophageal reflux, hyperventilation, vocal cord dysfunction and sleep apnoea, should be sought as these may be a cause of glucocorticosteroid treatment failure and pseudo-SRA, and may respond to alternative treatment.

3/221. A smoker with paroxysmal dyspnea.

    A 40-year-old woman who had experienced recurring episodes of dyspnea for 28 years presented to the emergency department with increasing shortness of breath, wheezing, and dry cough of three days' duration. She had been seen at another hospital shortly after symptoms began but left against medical advice. She did not have fever, chills, or other symptoms of upper respiratory infection.

4/221. bronchiectasis: the 'other' obstructive lung disease.

    bronchiectasis belongs to the family of chronic obstructive lung diseases, even though it is much less common than asthma, chronic bronchitis, or emphysema. Clinical features of these entities overlap significantly. The triad of chronic cough, sputum production, and hemoptysis always should bring bronchiectasis to mind as a possible cause. Chronic airway inflammation leads to bronchial dilation and destruction, resulting in recurrent sputum overproduction and pneumonitis. Once the diagnosis is confirmed, any potential predisposing conditions should be aggressively sought. The relapsing nature of bronchiectasis can be controlled with antibiotics, chest physiotherapy, inhaled bronchodilators, proper hydration, and good nutrition. In rare circumstances, surgical resection or bilateral lung transplantation may be the only option available for improving quality of life. prognosis is generally good but varies with the underlying syndrome.

5/221. Severe steroid-dependent asthma with IgG-2 deficiency and recurrent sinusitis: response to treatment with high-dose intravenous immunoglobulin.

    patients with severe asthma pose a dilemma to the physician since the treatment they need, namely high doses of oral steroids, has serious side effects, especially among the pediatric population. Deficiency in one or more of the IgG subclasses has been associated with abnormal pulmonary function, as well as with recurrent sinopulmonary infections in adults and children. In the last years attention has been focused on alternative therapies for these patients. One of these alternatives is the treatment with intravenous immunoglobulin (IVIG). We report an 11-year-old boy with severe asthma since the age of two years and multiple hospital admissions due to asthmatic crisis even more frequent and severe, to the point of needing, in the last year, daily treatment with high doses of oral steroids (20 mg). During six months the patient was given high doses of intravenous immunoglobulin. After one month of treatment a clinical and spirometric improvement was apparent allowing to taper down the oral steroids until their complete substitution by inhaled budesonide (1,600 microg/day). The only side effects noted were severe headaches after gammaglobulin infusions which responded well to oral paracetamol. This improvement was sustained throughout the treatment period, but few weeks after the IVIG was suspended the clinical and spirometric parameters started to worsen again.

6/221. vocal cord dysfunction in a child.

    vocal cord dysfunction (VCD) involves paradoxical adduction of the vocal cord during the respiratory cycle. This usually occurs during inspiration, but can also be seen in expiration. Vocal cord appositioning produces airflow obstruction sufficient to cause wheezing, shortness of breath, chest tightness, and coughing. These symptoms often imitate the respiratory alterations of asthma, thus leading to inappropriate treatment; intubation or tracheotomy may prove necessary. An 11-year-old girl was admitted with intractable dyspnea. She had been diagnosed with atopic asthma, although she failed to respond to an increase in antiasthma medication, including high-dose oral steroids. Flow-volume loops were abnormal, with evidence of variable extrathoracic airway obstruction, manifested as a flat inspiratory loop. No structural abnormalities were seen with either computed tomography (CT) or magnetic resonance imaging (MRI). Fibroscopy revealed paradoxical adduction of the vocal cords during the respiratory cycle, no obstructive disorder being observed. After the diagnosis of VCD, the clinical manifestations resolved with psychiatric treatment. Adduction was not demonstrable at repeat fibroscopy after treatment. VCD may simulate bronchial asthma; it may also be associated with that disorder, thus masking the diagnosis. It should be suspected in patients with recurrent wheezing who fail to respond to usual asthma treatment. An early diagnosis avoids unnecessary aggressive management. Treatment should consist of respiratory and phonatory exercises; psychotherapy may be useful.

7/221. asthma due to inhaled chemical agents--the macrolide antibiotic spiramycin.

    One year after starting work in the pharmaceutical industry a 35-year-old non-atopic maintenance engineer developed attacks of sneezing, coughing and breathlessness. These occurred at home during the evening and early morning, never at work during the day. His employment involved contact with a wide variety of chemical agents including the macrolide antibiotic spiramycin. inhalation challenge tests carried out in hospital with gradually increasing quantities of spiramycin reproduced his symptoms and led to the development of late asthmatic reactions, during which the FEV1 fell by 25% and the FEV1/FVC ratio by 15%. No change occurred in the single breath CO transfer factor nor were crepitations heard over the lung fields which remained normal on chest X-ray. The patient showed positive immediate skin prick tests to spiramycin and developed blood eosinophilia during the late asthma attacks. inhalation of sodium cromoglycate either before, or before and hourly after the provocation challenge for 6 hr, failed to prevent the late asthma, although its onset was further delayed. On leaving the pharmaceutical industry the patient's symptoms improved but did not finally clear until his wife, who had worked in a clerical capacity in the same factory also ceased her employment.

8/221. Seven cases of complete and incomplete forms of churg-strauss syndrome not related to leukotriene receptor antagonists.

    BACKGROUND: Various forms of churg-strauss syndrome have been reported in association with the use of leukotriene receptor antagonists in asthmatic patients. OBJECTIVE: Our purpose was to increase awareness that different forms of the churg-strauss syndrome occur in patients not receiving leukotriene modifiers. methods: We searched for all the cases of churg-strauss syndrome that were seen in the University of Rochester Medical Center, new york, in the past 4 years. RESULTS: We identified 7 patients, 6 of whom fulfilled the American College of rheumatology criteria for the classification of churg-strauss syndrome. None of them used leukotriene receptor antagonists. All had asthma and sinus disease. The duration and severity of their asthma varied considerably. In the majority of the patients the features of churg-strauss syndrome became obvious as the systemic corticosteroid dose was being tapered or discontinued, although 3 patients had not been receiving maintenance oral corticosteroids at disease onset. Three patients had positive antineutrophil cytoplasmic antibodies test result (perinuclear pattern). There was histologic documentation of vasculitis in 4 patients. Five of 7 patients responded to high-dose corticosteroid treatment. CONCLUSION: Our 7 cases are similar to the various forms of churg-strauss syndrome that have been reported in association with the leukotriene receptor antagonists. Complete or incomplete forms of this syndrome can become apparent in asthmatic patients as systemic corticosteroids are being tapered but can also occur in patients with mild asthma of short duration who use only inhaled corticosteroids.

9/221. Tracheal neurilemmoma mimicking bronchial asthma--a dilemma of difficult diagnosis: case report.

    Tracheal tumors are often overlooked as a cause of pulmonary symptoms until they reach an advanced state. They are often presented with a prolonged cough and shortness of breath. Most tracheal tumors in adults are cancerous (80% to 90%). Benign tracheal tumors are rare in adult patients. A case history is presented of a 19-year-old patient with a rare tracheal neurilemmoma. He was treated as having bronchial asthma initially, but his signs and symptoms did not improve with traditional therapy. The possibility of the presence of an upper airway obstruction was not raised until the typical "inspiratory tubular sound" was heard. Flow-volume loop testing, bronchoscopy, and three-dimensional computed tomography (3-D CT) confirmed the diagnosis of upper airway obstruction caused by a tracheal tumor. Therefore, surgical intervention rather than bronchoscopic removal was performed without difficulty. The patient was leading a stable life 8 months after a surgical resection. The presence of an upper airway obstruction can be proven by flow-volume loop testing and 3-D CT. Further pathologic confirmation can be accomplished by bronchoscopy. High suspicion of an upper airway obstruction such as a tracheal lesion should be raised when bronchial asthma patients fail to respond to conventional treatment.

10/221. Cardiac involvement and left ventricular failure in a patient with the churg-strauss syndrome.

    The churg-strauss syndrome is characterised by a history of asthma and paranasal sinus disease, eosinophilia of more than 10 per cent, non-fixed pulmonary infiltrates on chest radiography and vasculitis which may affect multiple organ systems. The condition usually manifests in the 4th decade. We present a 21-year old female with a history of asthma since one year of age who developed symptoms and signs of pneumonia, a pulmonary infiltrate on chest radiography and eosinophilia. This was followed a few weeks later by vasculitis which affected the skin and myocardium and associated with a peripheral eosinophilia of more than 80%. physical examination revealed palpable purpura and signs of left ventricular failure. echocardiography confirmed significant diminution of left ventricular contractility. A rapid improvement was observed after steroid therapy. echocardiography after two months showed normal left ventricular function. In this presentation we review the cardiac manifestations of the churg-strauss syndrome and its management.
