The authors studied 20 patients undergoing operation for a carcinoma of the middle third of the oesophagus during the period January 1972 to April 1975. Postoperative pulmonary complications are extremely common in such patients. All the patients had pulmonary function study results which were compatible with this type of surgery. All underwent resection with oesophagogastric anastomosis via a left thoracophrenolaparotomy. Of the 20 patients, 14 suffered from one or more episodes of acute respiratory insufficiency, some related to pneumonia. On the basis of various associated clinical, radiological, biological, evolutive and histopathological criteria, five types of pulmonary complication were distinguished: 1-Shock lung; 2-Infective pneumonia; 3-Traumatic pulmonary disease; 4-Acute cor pulmonale; 5-Lung disease of undetermined origin. Twelve patients died as a result of pulmonary complications, 11 early (before the 16th day). One patient only died as a result of rupture of the oesophagogastric anastomosis.

Four children who developed severe lung disease after measles are described. One child died and three have been left with severe impairment of lung function. It is suggested that secondary infection with an adenovirus was responsible for causing the lung disease in these patients. The immune response to measles was abnormal. Measles virus may have rendered the children more susceptible to serious complications from infection with the adenovirus. The many deaths from 'measles pneumonia' in developing countries and the occasional occurence of post-measles bronchiectasis in this country may be due to secondary adenovirus infections. Further viral and serological studies are required to confirm this hypothesis.

In a prospective study of patients with acute pneumonia, the results of bacteriologic analysis of sputum, transtracheal aspirate (TA), and bronchial aspirate (BA) were compared. Streptococcus pneumoniae was grown from all three sources as the predominant organism in 13 of 16 cases; the remaining three patients had nonbacterial lung disease. These data support the traditional concept that culture of the sputum is highly reliable in providing a correct diagnosis in acute pneumonia.

A 5-year-old boy with acute lymphoblastic leukemia in complete continuous remission developed life-threatening varicella pneumonia and acute respiratory insufficiency (ARI). The child recovered after 92 hours of partial venoarterial perfusion with a membrane oxygenator. Functional asplenia developed. Serial pulmonary function tests after perfusion indicate moderately severe restrictive lung disease which has slightly improved during an 18 month period.

We undertook a randomized clinical trial to evaluate the efficacy of chest physiotherapy and intermittent positive-pressure breathing in the treatment of pneumonia. The diagnosis of pneumonia required a compatible clinical history and x-ray confirmation. A total of 54 patients were assigned to treatment and control groups and were similar in age, smoking history, underlying lung disease and prior antibiotic treatment. Antibiotic therapy, guided by Gram stain and sputum and blood cultures, was similar in both groups. Chest physiotherapy, consisting of postural drainage, percussion and vibration, was given concurrently with intermittent positive-pressure breathing with use of racemic epinephrine every four hours. There was no statistically significant difference in duration of fever, extent of radiographic clearing, duration of hospital stay and mortality between the control and treated groups. Chest physiotherapy and intermittent positive-pressure breathing do not hasten the resolution of pneumonia.

Platypnea nad orthodeoxia developed during an episode of adult respiratory distress syndrome in a previously healthy individual. An outstanding feature of the patient's illness was the development of numerous pneumatoceles secondary to necrotizing pneumonia. These abnormalities spontaneously improved with improvement of the underlying parenchymal lung disease.

A previously unrecognized autosomal dominant syndrome affecting oral, nasal, vaginal, urethral, anal, bladder, and conjunctival mucosa with cataracts, follicular keratosis, nonscarring alopecia, and terminal lung disease is described in a four-generation kindred of German extraction. Severe photophobia, tearing, and nystagmus in infancy heralds the development of keratitis, corneal vascularization, and lens cataracts. Repeated corneal transplants have failed. Red, periorificial mucosal lesions involving the above structures are noted by 1 year of age and may persist throughout life. Chronic rhinorrhea and repeated upper respiratory infections frequently progress to bilateral pneumonia accompanied by loss of hair, diarrhea, occasional melena, enuresis, pyuria, and hematuria. Spontaneous pneumothorax is frequent, terminating in fibrocystic-type lung disease and cor pulmonale. Women have had repeated abnormal vaginal PAP smears. Histologically the mucosal epithelium shows dyshesion, thinning of the epithelial layer, and dyskeratosis. Mucosal PAP smears show lack of epithelial maturation, cytoplasmic vacuoles and inclusions, and individual cell dyskeratosis. Histochemically there is a lack of cornification and keratinization. Ultrastructural studies show lack of keratohyalin granules, a paucity of desmosomes, intercellular accumulations, cytoplasmic vacuolization, and formation of bands and aggregates of filamentous fibers and structures in the cytoplasm resembling desmosomes and gap junctions. The condition is probably a panepithelial cell defect of desmosomal and gap junction structure most prominently affecting mucosal epithelia associated with an increased susceptibility to a variety of adventitious organisms.

A high proportion of Cree and other North American Indian children have a chronic cough and many have bronchial wall thickening on radiographs, reminiscent of white children with asthma, mild cystic fibrosis, or immune deficiency. When compared to postmortem studies, radiographs underestimate the degree of bronchial wall thickening present. As compared to white children, Indian children in the first two years of life are more susceptible to recurrent bronchitis and pneumonia, are much more likely to develop pneumonia with rubeola and pertussis, and are more likely to develop chronic lung disease after adenovirus infections. Staphylococcal complications with pneumatocele formation are more common. A greater number acquire pneumonia while in hospital with other medical or surgical problems. Indian children with pneumonia recover more slowly, and some continue to deteriorate even after admission to hospital.

Electron microscopic studies of lung were made and compared in 17 patients with lung disease (10 with idiopathic pulmonary fibrosis, 3 with collagen--vascular diseases, 3 with sarcoidosis, and 1 with chronic eosinophilic pneumonia) and in 5 control patients. In control patients, the alveolar epithelial cells were normal, and no hemidesmosomes were present between the plasma membranes and the basal laminae. In comparison, cuboidal alveolar epithelial cells were present in 15 of the patients with fibrotic lung disease; in 9 of these the alveolar epithelial cells were multilayered. In 7 of the latter 9 patients (5 with idiopathic pulmonary fibrosis and 2 with collagen-vascular diseases), the basal laminae of the alveolar epithelial cells were attached to the plasma membranes by hemidesmosomes and to the underlying interstitial connective tissue by "anchoring fibrils." These fibrils measured from 4000 to 6000 A in length and from 200 to 600 A in width. One or both ends of the anchoring fibrils inserted into thebasal lamina, often forming arcs through which collagen fibrils and connective tissue microfibrils penetrated. Anchoring fibrils showed a complex pattern of transverse banding, which differed from that of collagen and appeared to be symmetric about the center of the fibril. These anchoring fibrils, which resemble those in normal skin and other tissues, were not found in lungs of control patients. In addition, there was a significant correlation between the severity of the pulmonary fibrosis and the presence of anchoring fibrils. These observations suggest that in severe fibrotic lung disease, anchoring fibrils reinforce the attachment of the basal lamina of multilayered alveolar epithelial cells to interstitial connective tissue.

During a 5-year period, 1969-1973, 451 patients with acute severe pulmonary diseases were admitted to the three medical intensive care units (MICU) at Ullevaal Hospital. In 39% of the patients a major cardiac arrhythmia was recorded in the units during a mean observation time of 24 h. The subsequent mortality in the hospital was 31% in patients with arrhythmias in the MICU, and 8% in patients without arrhythmias. The association between arrhythmias and mortality was significant (P less than 0.004) in patients with a diagnosis of pneumonia. There was also an association (P less than 0.04) between arrhythmias and the severity of lung disease. Continuous electrocardiographic monitoring of patients with severe pneumonia or acute exacerbations of obstructive lung disease is recommended.
