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.

A consecutive series of 282 nurses of the University Hospital, Groningen, with complaints of the nose and/or throat associated with coughing and/or hoarseness were examined between April 1965 and February 1968. The intent was to obtain information on the incidence of viral, mycoplasma and bacterial infections, and on the relationship of these infections in nurses with chronic nonspecific lung disease (CNSLD). The following results were obtained: 1. Virus infections caused by influenza virus (A, B, and C), rhinovirus, parainfluenza virus, adenovirus, respiratory syncytial virus and/or Mycoplasma pneumoniae were confirmed in 30% of the nurses examined; if influenza was excluded, this figure was 20%. 2. Rhinovirus infections were found more often than all the other virus infections together (if influenza was excluded). 3. Approximately 25% of the nurses had signs of CNSLD. 4. In the course of the virus infections, nine out of 14 nurses with a history of chronic obstructive lung disease showed symptoms of exacerbation or recurrence of a generalized bronchial obstruction. 5. There was no difference in the incidence of virus infections in the group of nurses with and without CNSLD. 6. There were more bacterial infections (without a confirmed virus infection) in the subjects with CNSLD than in those without CNSLD. 7. There were more combined viral/bacterial infections in the patients with CNSLD than in those without CNSLD. 8. Patients with influenza did not have more bacterial infections than patients with other virus infections. This is also true for patients with CNSLD and influenza when regarded separately. The patients without CNSLD tended to have more bacterial infections with influenza than with other viral infections, but the difference was not statistically significant.

Among 40 hospitalized infants and children with cytomegalovirus infection, 14 (35%) had interstitial pneumonitis, 4 (10%) had wheezing or tachypnoea but without x-ray evidence of classical interstitial pneumonia, the remaining 22 (55%) were free of pulmonary involvement. Most patients had tachypnoea and nonproductive cough of varying durations: those with underlying pulmonary pathology tended to have persistent and prolonged respiratory symptoms. Mortality and severity of the lung disease were related to the underlying immunodeficiency or concomitant pulmonary process.

The effect of coughing on the elimination of inhaled 6 micrometer radioactively tagged teflon particles in humans was studied by external measurements of the radioactivity retained in the lungs before and after 1--2 min of voluntary coughing. In six healthy subjects coughing produced no substantial elimination of the particles. Six out of eight patients with lung disease produced expectorate and also eliminated particles from the lungs by coughing. The other two patients had no phlegm, did not produce any expectorate and did not eliminate particles by coughing. An increased amount of tracheobronchial secretion thus seems to be necessary for coughing to be effective. In the patients, the elimination of particles by coughing was fairly reproducible, suggesting that the test model may be useful for investigation of the influence of physiological and pharmacological factors on the elimination process.

Forty-one consecutive patients with suspected sarcoidosis underwent pulmonary function testing and transbronchial lung biopsy at three community teaching hospitals. Transbronchial biopsy disclosed noncaseating granulomas in 22 of 23 patients (96%) in whom parenchymal disease was roentgenographically apparent and in eight of 18 patients (44%) in whom it was not. The stage of the disease as determined by the chest roentgenogram was the most reliable determinant for a positive biopsy result. Not the presence of cough, dyspnea, or constitutional symptoms or pulmonary function as measured by forced vital capacity and carbon monoxide diffusing capacity served to predict a positive transbronchial biopsy finding any more accurately than did the roentgenographic staging of the disease itself. This study suggests that while transbronchial lung biopsy may be an acceptable initial diagnostic procedure in suspected sarcoid patients without parenchymal lung disease, clinical symptoms and pulmonary function abnormalities are not helpful in predicting the liklihood of a positive biopsy result.

The prevalence of chronic lung disease was investigated in 1284 adult residents of 11 villages situated at 1800 m in the Highlands of Papua New Guinea. Chronic cough, shortness of breath on exertion, bronchial hypersecretion, and adventitious chest sounds were increasingly common in both sexes from middle life onwards, and were associated with an irreversible obstructive ventilatory defect. Over the age of 45 years, 20% of men and 10% of women had an FEV1/FVC % less than 60%. The prevalence of active asthma was 0.25%. The smoking of home-grown, air-cured tobacco was not associated with chronic respiratory symptoms or reduction of ventilatory capacity. Smoking was, however, associated with recent cough symptom, bronchial hypersecretion and adventitiae. Mortality over the subsequent 5 years was increased 2--3 fold in those with adventitiae, but was not related to smoking status. The aetiological relevance of wood smoke in the houses and acute chest infections remains to be clarified.

A 47-year-old woman presented with cough, pleuritic chest pain and fever of three weeks duration. Although the patient lived in an area where blastomycosis is endemic, this diagnosis was not initially considered owing to the presence of consolidation and a large pleural effusion on the initial chest roentgenogram. Cultures of sputa, bronchial washings and pleural fluid documented the presence of pleuropulmonary infection with Blastomyces dermatitidis. Therapy with amphotericin B was associated with rapid clinical, roentgenographic and bacteriologic resolution of both pleural and parenchymal lung disease.

Pulmonary disease has been associated with several chemotherapeutic agents but has not been reported in patients receiving the alkylating agent mitomycin (Mutamycin). We describe here the cases of three patients who developed interstitial pneumonia while receiving mitomycin therapy. Their clinical features including dyspnea, cough, and occasionally fever; reticular infiltrates were seen on chest roentgenogram. Histologically, diffuse alveolar septal edema, mononuclear-cell interstitial infiltrates, hypertrophy of alveolar lining cells, and alveolar septal collagen deposition were characteristic. Treatment with corticosteroids was associated with a rapid therapeutic response in all three patients.

A 24 year old man had a nonproductive cough and chest pain. Chest roentgenogram showed a diffuse infiltrate, and pulmonary function studies showed restrictive lung disease. Extremity weakness, deteriorating mental status and neuropathy progressed as pulmonary findings diminished on corticosteroid therapy. Lung biopsy showed lymphomatoid granulomatosis. The neurologic status deteriorated despite treatment with Cytoxan, intrathecal methotrexate and brain irradiation. Autopsy showed mass lesions of lymphomatoid granulomatosis in the brain and healed lesions in the lungs. A review of the neurologic and pulmonary findings in reported cases show that diminution of pulmonary disease with progression of neurologic disease manifest by mass lesion is unusual. Since the etiology, prognosis and prevalence of this disease remains undefined, all patients with this disease should be reported on.

Forty-five patients (25 male and 20 female) over 12 years of age with cystic fibrosis have been studied clinically, radiologically and physiologically. Their mean age at the first visit was 17 years; they were followed for a mean period of 4 years and attended at least every six months. The first symptom which developed before the age of five in 42 of the 45 patients was respiratory. Thirty-two of the 45 patients had severe lung disease (Group III) at the start of the study of the seven patients died during the study. Cough and sputum were almost universal, 23 had haemoptyses and eight pneumothoraces. Staphylococcus pyogenes, Haemophilus influenzae and Pseudomonas aeruginosa were the common pathogens isolated from sputum and the increasing prevalence of the latter was again confirmed. Acquisition of the mucoid strain of pseudomonas signified poor prognosis. Established infection was never eradicated. Forty-three patients had evidence of pancreatic insufficiency; in all but one patient the symptoms were mild and five patients abandoned dietary restriction and pancreatin without ill effect. Seven patients had symptoms of partial bowel obstruction (meconium ileus equivalent) but only one required surgical relief. The liver was enlarged in seven patients and the spleen was felt in three. Three patients had diabetes mellitus. The influence of cystic fibrosis on growth and development is reported--the growth spurt is late in the majority but growth failure is not confined to those with severe lung infection or malabsorption and in these circumstances remains unexplained. Mean weight was low in relation to height and puberty was delayed in both sexes.
