Intrapleural pressure, the tracheal air flow and tidal volume were recorded simultaneously in pentobarbital-anaesthetized dogs and changes occurring in them during defensive reflexes elicited by mechanical stimulation of the mucosa of different parts of the respiratory tract were evaluated quantitatively. The results show that, in addition to coughing and sneezing provoked by inserting a nylon fibre into the tracheobronchial region, the larynx and the nose, further respiratory reflexes described in other mammals also appear in these animals. Mechanical stimulation of the epipharynx with a fine polyvinylchloride catheter, for instance, also produces in dogs an aspiration reflex characterized by sniff-like inspiratory efforts without subsequent active expiration. Touching the vocal folds, however, produces an expiration reflex consisting of expiratory efforts without preceding inspiratory effort. The character of all these reflexes is typical and closely resembles their character in cats. Stimulation of the various parts of the respiratory tract sometimes evokes an apnoeic reaction instead of typical respiratory defensive reflexes.

A heavy infestation of the tussock moth caterpillar (Orgyia pseudotsugata McDonnough) in forested areas of Oregon was associated with itching of the skin and eyes, nasal discharge, cough, and, at times, respiratory difficulty, Personal interviews and inspection of forty-one occupationally exposed persons were supplemented by a questionnaire administered to 428 individuals, composing three groups at various degrees of risk and a control group. There was a cause and effect relationship between the adverse symptoms and the exposure to tussock moth larvae. The specific etiologic agent was not identified, but it was felt that the secretion, hairs, or other substances in the larvae or cocoons of the moth acted as a potent allergenic substance and, for some persons, was also a primary skin irritant.

Acute massive pulmonary hemorrhage is described as part of the clinical picture of SLE. Seven patients had sudden onset of high fever, dyspnea, tachycardia, and cough with blood-tinged sputum that within hours progressed to massive hemoptysis and death. There were no vasculitis or other inflammatory lung changes found at autopsy. Only one of the seven reported cases survived when treated with 2 g of intravenous hydrocortisone daily. The mechanism of this pulmonary bleeding is unknown but seems to be an immune complex mediated phenomenon.

There is increased recognition of hypersensitivity lung disease among workers with laboratory animals as an occupational disease. Symptoms of asthma in 44 of 78 workers with laboratory animal dander allergy reflected the serious consequences of this occupational ailment. Affected employee profiles induced family history of atopy; immediate (Type I) allergic reaction; symptoms of rhinitis, asthma, and cough; hypersensitivity to one or more species, most often rats, mice, and rabbits. Diagnosis depends on history and physical, radiologic, and laboratory examinations, including skin tests with relevant antigens. Control and treatment depend on environmental change (reemployment or reduction of antigen contact); mechanical devices (masks and filters); chemotherapy (bronchodilators, steroids), prophylaxis and immunotherapy (hyposensitization). Standardization of medico-legal criteria covering occupational asthma is needed.

Eight mature horses which had been affected with a moist cough for six weeks were found to have large numbers of eosinophils in tracheal mucus samples taken by transtracheal washing. These horses were kept on irrigated pasture and fed a hay-free diet. A companion yearling donkey was found to be passing Dictyocaulus arnfieldi larvae in its faeces. Two oral treatments with a dose of thiabendazole (440 mg/kg) resulted in the resolution of the clinical signs and the disappearance of eosinophils from transtracheal washings. The eosinophilic bronchitis seen in these horses was presumed to be a manifestation of prepatent D arnfieldi infestation.

The authors describe changes in the cough reflex in unanaesthetized cats with experimental local tracheitis. Inflammation was produced by a silk suture fixed in the trachea and cough was elicited by mechanical stimulation of different parts of the respiratory tract mucosa. The resultant cough values (the number of efforts, the intensity of the maximum effort and the intensity of the attack) were compared with the corresponding values in healthy cats. In animals with a tracheal suture, inflammation was confined to the trachea. The intensity of cough elicited by stimulation of this region increased significantly compared with normal (on the 15th to 17th day of inflammation), whereas cough elicited from the laryngopharyngeal and tracheobronchial region did not. On about the 20th day of inflammation the authors found a decrease in the intensity of the maximum effort of cough elicited from the inflamed part of the trachea and a decrease in the intensity of the maximum effort and the intensity of the coughing attack elicited from the laryngopharyngeal and tracheobronchial region. They assume that the decrease could have been due to the development of protective inhibition in central structures participating in integration of the cough reflex.

Extensive resection of the abdominal wall was performed on six patients to reconstruct defects caused by tumors or necroses. Autologous dermis covered by a flap plasty produced good clinical and functional results, documented by the measurement of intraabdominal pressures in response to coughing, pressing, and lifting of the legs. The autologous dermis graft represents a valuable tool for the closure of large defects of the abdominal wall.

Twenty patients with pathologically proved non-resectable bronchogenic carcinoma were treated with 100 aerosolized BCG (Tice strain) doses in addition to conventional treatment. The procedure is based on findings that, generally BCG must be closely associated with neoplastic cells to be effective as an immunotherapeutic agent. Bronchogenic malignancy, usually of mucosal origin, is logically treated in this manner. We report here the findings and developments of 10 patients who were treated at least five times each (for a total of 81 treatments) and pertinent experience relating to these and another 10 patients treated a total of 19 times. Local and systemic reactions were frequent and consisted of fever, cough, dyspnea, nausea, vomiting, anorexia, and malaise. Four of the 20 patients (20%) had reactions with the first treatment; by the fourth treatment 6 of 6 (100%) were affected. Prednisone given prophylactically reduced the intensity and the frequency of reactions. There were no severe side effects, obvious BCG infections, or significant changes in pulmonary or liver functions or hematologic values. No patient acquired purified protein derivative sensitivity, although 3 persons converted other skin tests to positive. There was no improvement in actuarial survival time.

A prospective study of 125 chemical workers was carried out for ten years to investigate the incidence of lung cancer. Some of the men were exposed to chloromethyl methyl ether containing bis(chloromethyl) ether as an impurity. Bronchogenic carcinoma was markedly increased among them, with a strong dose-response relationship. An unexpected inverse relationship was noted between smoking and the incidence of lung cancer. The neoplasms (all small-cell carcinomas) occurred in relatively young men. Symptoms of chronic bronchitis were reported more often among men exposed to chloromethyl ether, and a dose-response relationship was apparent, with smoking a cofactor. Ventilatory function was not significantly affected by chemical exposure. Periodic screening over the first five years of the study showed a decrease in chronic coughing and an increase in dyspnea while chemical exposure was diminishing.

Three cases illustrate the principal clinical and roentgenographic varieties of granular cell myoblastoma (GCM) of the lung. The vast majority are small benign intrabronchial tumors without roentgenographic findings. These remain asymptomatic and are detected accidentally at autopsy, surgery, or bronchoscopy (Case III). Larger obstructing lesions (Case I) cause focal atelectasis or pneumonitis, leading to cough, expectoration, and hemoptysis. Hilar enlargement from reactive lymph node hyperplasia is common. Clinically and roentgenographically these are indistinguishable from bronchial adenomas. Least often the tumor extends entirely extrabronchially (Case II) presenting as a parahilar parenchymal asymptomatic nodule, simulating a granuloma, hamartoma, arteriovenous malformation or a neoplastic nodule.
