One year's experience with MAS in a neonatal intensive-care unit is analyzed with follow-up information. Seventeen patients or 3.7% of all admissions had MAS. Four patients (23.5%) died of acute respiratory failure. Two patients with MAS and persistence of the fetal circulation required cardiac catheterization to exclude cyanotic congenital heart disease. No survivors had persistent chronic lung disease. However, two of three patients with MAS and seizures had significant psychomotor retardation at follow-up examination.

In reviewing the present-day status of cor pulmonale, it is clear that considerable progress has been made in almost all instances of the disease. It is clearly a preventable form of heart disease in most cases and it is treatable and curable in its most common form, i. e., in COPD. One must agree with Petty, that today we have effective means of caring for the majority of respiratory cripples. Therapy for lung disease now appears even to have reduced the expected rate of pulmonary function deterioration in some patients. Surely with improved gas exchange and early detection of respiratory insufficiency the outlook for patients with respiratory diseases leading to cor pulmonale is better today than it was 30 years ago.

The authors report 6 cases of acute respiratory failure complicating chronic bronchial and lung disease admitted to hospital with the diagnosis of: heart disease, 3 cases, pulmonary oedema, pulmonary embolism, atrial flutter; status asthmaticus : one case; neuro-psychiatric disease : 2 cases (toxic coma and agitation). The authors emphasize the frequency of chronic bronchial disease and recall the signs of acute decompensation discussing the possible difficulties in diagnosis and the therapeutic implications.

Electrocardiographic monitoring of 52 consecutive patients undergoing upper gastrointestinal endoscopy revealed that arrhythmias during the procedures were common (38.5%) and tended to occur more frequently in the elderly (75%), in persons with heart disease (54.5%), and in persons with chronic lung disease (89%). The incidence of ventricular premature contractions in patient with no evidence of heart or lung disease was 19%. In one patient with advanced chronic lung disease, the procedure had to be terminated because of development of high-degree atrioventricular block. A high incidence of arrhythmias during endoscopy has not been previously reported in patients with chronic lung disease.

Pulmonary diffusive capacity by the carbon monoxide method was evaluated in 43 patients two years after myocardial infarction, and without evidence of other types of heart disease. The patients did not have primary lung disease or clinic bronchitis. Special interest was given to the effects of cigarrette smoking and moderate pulmonary congestion. A significant decrease in diffusion capacity was observed in smokers and former smokers compared to none smokers. In moderate pulmonary congestive the oposite effects was registered. pO2 was decreased in half the patients with old myocardial infarction but there was no significant statistical correlations with D1co values. Mean values for pO2, pCO2, pH, EB did not show statistically valid differences among the subgroups under study. Different factors which may influence the evaluation of diffusion capacity are discussed.

During a gradually increasing exercise test heart rates were determined in healthy animals and in 2 groups of sick horse. These included 31 animals with a chronic pulmonary disorder and 5 with chronic heart disease. The alteration in heart rate was correlated with the clinical signs exhibited. In the horses with lung disease there was a close correlation between the stage of the diseases and the heart rate during the exercise test. In 3 animals with heart valve disease there was no apparent difference in heart rate compared with healthy horses. On the other hand the exercising heart rate of horses with atrial fibrillation showed a significant increase. The recovery rate of pulse and respiration after a 20 min trot did not show any correlation with the stage of disease or the pulse and respiration after a 20 min trot did not show any correlation with the stage of disease or the results of gradually stepping up the exercise in horses with lung disease.

Arterial oxygen tension was measured from radial artery samples in 276 infants referred for cardiological investigation. Values obtained during air breathing in infants with congenital heart disease showed considerable overlap between 'cyanotic' and 'acyanotic' groups, and are of limited diagnostic use. By contrast, values obtained while breathing oxygen in concentrations of over 80%, measured in 182 infants, allowed clear differentiation between these groups. All infants with acyanotic, but only 2 of 109 with cyanotic lesions, achieved an arterial oxygen tension of more than 150 mmHg. In the cyanotic group the response to oxygen breathing was significantly greater in common mixing situations and in the hypoplastic left heart syndrome than with either pulmonary outflow tract obstruction or transposition of the great arteries. Infants with transposition had a significantly lower mean arterial oxygen tension in air than infants with other forms of cyanotic congenital heart disease. Of 23 infants whose final diagnosis was primary lung disease but in whom cyanotic congenital heart disease had been suspected, 7 achieved arterial oxygen tensions of more than 150 mmHg during oxygen breathing, and on this basis cardiac catheterization was not performed. We therefore conclude that measurement of the arterial oxygen tension while breathing high concentrations of oxygen should be routinely performed in the initial assessment of sick infants with suspected congenital heart disease.

Chest radiographs of 39 patients with ankylosing spondylitis were studied. Three showed apical pulmonary fibrosis, two with cavitary lesions. Other known causes of lung disease were excluded. Symptoms and roentgenographic evidence of spondylitis were present for many years prior to the onset of pulmonary symptoms, which variably included shortness of breath, cough, hemoptysis, pleuritic chest pain, fever, and chills. Apical pulmonary lesions of unknown cause were absent in 53 age, sex, and racematched osteoarthritis control patients. The findings suggest that apical pulmonary fibrosis may be an extra-skeletal manifestation of ankylosing spondylitis, the frequency of which approaches that of spondylitic heart disease.

Family practitioners in Georgia and South Dakota were surveyed in order to ascertain percentage of practice devoted to various specialty areas, daily case loads, type of diagnoses, method of handling telephone calls, and patterns of agency utilization. Questionnaires were sent to all South Dakota and Georgia family practitioners. In Georgia 22% of family practitioners do no surgery and 55% do no obstetrics, while in South Dakota 90% practice obstetrics. Differences in availability of specialists and in pysician referral patterns caused marked variations in family practice patterns. Diagnoses showing geographic differences included chronic lung disease, arthritis, sore throat, heart disease, and neuroses. About 50% of all physicians handled medical phone calls personally. Less than half the respondents in each state used some agency or resource in this time period. The distribution of specialists affects the patient load and needs to be considered when primary care is planned.

To explore whether exposure among firefighters to fire smoke could lead to an increased risk of cancer, lung disease, and heart disease, the mortality of 4546 firefighters who were employed by the cities of Seattle and Tacoma, WA and Portland, OR for at least one year between 1944 and 1979 were compared with United States national mortalities and with mortality of police officers from the same cities. Between 1945 and 1989, 1169 deaths occurred in the study population and 1162 death certificates (99%) were collected. Mortality due to all causes, ischaemic heart disease, and most other non-malignant diseases was less than expected based upon United States rates for white men. There was no excess risk of overall mortality from cancer but excesses of brain tumours (standardised mortality ratio (SMR) = 2.09, 95% confidence interval (95% CI) 1.3-3.2) and lymphatic and haematopoietic cancers (SMR = 1.31, 95% CI = 0.9-1.8) were found. Younger firefighters (< 40 years of age) appeared to have an excess risk of cancer (SMR = 1.45, 95% CI 0.8-2.39), primarily due to brain cancer (SMR = 3.75, 95% CI 1.2-8.7). The risk of lymphatic and haematopoietic cancers was greatest for men with at least 30 years of exposed employment (SMR = 2.05, 95% CI 1.1-3.6), especially for leukaemia (SMR = 2.60, 95% CI 1.0-5.4).
