A case of multiple granular cell myoblastomas of the tracheobronchial tree is presented. The patient is well 32 months following endobronchial removal. Only 46 cases of solitary and two cases of multiple lesions of the tracheobronchial tree have been described in the literature. These lesions occur with equal frequency in men and women; at a median age of 38 years; more frequently on the right than on the left; and most commonly with cough as the presenting symptom. Most patients have been treated with major surgical resections, but conservative endobronchial removal may be effective therapy.

We studied waking and ventilatory responses to laryngeal stimulation during sleep in three dogs. The dogs breathed through an endotracheal tube inserted caudally into the trachea through a tracheostomy. Laryngeal stimulation was produced either by inflating a small balloon that was positioned in the rostral tracheal segment, or by squirting water onto the larynx through a catheter inserted through the tracheostomy. Airflow was measured with a pneumotachograph, and sleep state was determined by behavioral, electroencephalographic, and electromyographic criteria. We found that the degree of laryngeal stimulation required to produce arousal and coughing was higher in rapid-eye-movement (REM) sleep than in slow-wave sleep (SWS). Stimuli that failed to cause arousal from SWS often produced a single expiratory effort, or brief apnea (1--2 s) and bradycardia. In contrast, during REM sleep subarousal stimuli often resulted in prolonged apnea (greater than 10 s) and marked bradycardia. We conclude that during REM sleep arousal responses to laryngeal stimulation are depressed, but ventilatory and cardiac responses are intact.

A prospective study of respiratory infections was performed in nineteen married asthmatics and their normal spouses who were examined at monthly intervals during a 1-year period. The colds described were associated with nasal symptoms, sore throat and usually malaise, fever, cough and hoarseness. The asthamtics reported a larger number of these symptomatic episodes than the non-asthmatics but significantly fewer of the episodes in the asthmatics were objectively confirmed by viral isolation or rise in serum titre of viral antibody. The frequency of respiratory infections was not influenced by the long term use of inhaled beclomethasone dipropionate and oral corticosteroid drugs. Less than 10% of the exacerbations of asthma were associated with respiratory infection. The disability resulting from respiratory infections in the asthmatics did not significantly exceed that in the non-asthmatics.

We studied waking, ventilatory, and reflex tracheal smooth muscle (TSM) responses to tracheobronchial irritation or lung inflation in three sleeping dogs. The dogs breathed through a cuffed endotracheal tube, and airflow was measured with a pneumotachograph. TSM tone was monitored directly by measuring pressure in the water-filled cuff of the endotracheal tube. Mild degrees of tracheobronchia irritation, produced by squirting 0.1--1.0 ml of water into the lower trachea, or by having the dogs inhale one breath of acetic acid vapor (concentration 17 ppm), generally caused arousal from slow-wave sleep (SWS), but not from rapid-eye-movement (REM) sleep. During wakefulness the irritant stimuli caused coughing and TSM constriction; during SWS or REM sleep, these responses occurred only if the stimulus first produced arousal. In contrast, stimulation of pulmonary stretch receptors by lung inflation did not cause arousal, but readily produced apnea and TSM relaxation during SWS. The results indicate that cough and airway smooth muscle constriction in response to bronchopulmonary irritant stimuli do not occur in the absence of arousal, and that arousal responses to such stimuli are depressed in REM sleep.

To assess clincial effects of precipitated amorphous silica (PAS), the authors reviewed serial spirograms, respiratory questionnaires, and chest radiographs of 165 workers exposed for a mean of 8.6 years. Monthly exposure was graded on a 1 to 4 scale and a "cumulative exposure index" (CEI) calculated for each worker from the sum of measured exposure. A "mean exposure index" (MEI) was calculated by dividing the CEI by total months exposed. Sputum production and dyspnea were inversely correlated with CEI, while cough and dyspnea correlated with mean pack-years of smoking but not PAS exposure. Linear regression analysis of yearly change of all pulmonary function variables (FVC, FEV1, FEV1/FVC, FEF25-75) showed no correlation with either the dose of PAS (CEI) or total years of exposure. Among 44 workers with a mean exposure time of 18 years (range 10-35 years), yearly decline of FVC and FEV1 were similar to the overall group. Of 143 workers with serial radiographs and exposure to only PAS, none had radiographic pneumoconiosis. Respiratory symptoms in PAS workers correlate with smoking but not with PAS exposure, while serial pulmonary function values and chest radiographs are not adversely affected by long-term exposure.

A 23-year-old woman, who had suffered recurrent acute bronchitis, dyspnoea, and stridor, was found to have a tracheal stenosis and complete left main bronchus obstruction. Biopsy of the tumour showed an adenoid cystic carcinoma. After pneumonectomy the trachea was closed through tumour tissue. Two weeks later a right thoracotomy showed that a tumour had invaded the trachea from the carina up to 6 cm and the right stem bronchus for 1 cm. Under extracorporeal circulation 7.5 cm of the trachea and right bronchus were resected. A direct tracheal anastomosis was easy to perform. Spontaneous respiration with efficient coughing returned after five days. Unfortunately, one month later, high fever caused by a lung abscess developed, which provoked a massive haemoptysis with fatal outcome.

In 36 patients with bronchial asthma a new inhalable corticosteroid (Fluocortin-butyl-ester) was administered to reduce systemic steroids and especially to study the recovery of pituitary-adrenal function. On the basis of the present results, it can be said that patients with the least degree of emphysema and obstruction and with good coughing dynamics and productive expectoration are most suitable for therapy with inhalable corticosteroids. If the systemic steroid reduction is adequate, the recovery phase of the pituitary-adrenocortical system begins after about 5 months and the response to ACTH appraoches normal values after about 8-9 months. About 4 mg prednisolone-equivalent per day can be assumed to be the systemically effective limiting dose. The reducibility as a percentage of the initial dose-regardless of its absolute value- and the maintenance dose achieved also appear to be of equal importance for the recovery of the functional reserve of the pituitary-adrenocortical system. No relationship to the duration of the disease and the initial steroid dose could be demonstrated. The clinical picture of the corticosteroid withdrawal syndrome is dependent on endogenous cortisol synthesis. The symptoms disappear spontaneously with increasing synthesis.

Thirty-three of 85 patients undergoing marrow transplantation between 1969 and 1973 developed interstitial pneumonia; 23 died. The clinical syndrome consisted of tachypnea, cough, fever, rales, and hypoxemia; the radiologic findings were variable. The development of interstitial pneumonia was significantly associated with graft-versus-host disease and allogenic grafting; patients with isogenic grafts were relatively spared. The increased attack rate between 1969-71 (20%) and 1972-73 (49%) was not fully explained by improved long-term survival, by an increased proportion of allogenic transplants, or by an increased incidence of graft-versus-host disease. Intranuclear inclusions typical of cytomegalovirus were identified in 9 of 17 autopsy-confirmed cases, and patients whose marrow donors had positive cytomegalovirus antibody titers developed interstitial pneumonia more often than patients whose donor had negative titers. Interstitial pneumonia is an important cause of morbidity and mortality after human marrow transplantation. No effective treatment is presently available.

Potassium guaiacolsulfonate, a highly polar, acidic substance, is readily eluted by chloroform from a pH 4.5 Celite column in the form of its ion-pair with trihexylamine, thereby effecting facile separation from other pharmaceuticals. The sulfonic acid is then back-extracted into aqueous alkali and determined spectrophotometrically. Assay of standard solutions by this procedre averaged 100.44 plus or minus 0.81%. The method was applied successfully to 4 commercial cough preparations containing a variety of other drugs.
