Three newborn infants are described with a distinctive pulmonary arterial lipid lesion, characterized by a wide foamy layer of intima partially occluding the lumen of small muscular pulmonary arteries. Lipid stains indicated lipid infiltration of the walls of these arteries, involving not only the intimal layer, but media and adventitia as well. All three infants had received intravenous lipid infusions. All three infants also had histologic evidence of pulmonary hypertension, one on the basis of chronic lung disease (BPD) and two on the basis of congenital heart disease. A retrospective autopsy study of long-term neonatal ICU dwellers receiving such infusions revealed two additional patients with lipid deposits in pulmonary arterial walls. It is speculated that the pulmonary arterial lipid deposits were derived from the lipid infusions and were dependent on antecedent or concurrent vascular damage from pulmonary hypertension.

147 case records of infants referred to the Brompton Hospital in the first year of life with a provisional diagnosis of congenital heart disease were examined. Statistical analyses were performed to evaluate selective criteria for the allocation of these infants into a group with lung disease, or into 1 of 5 major haemodynamic groups--namely, acyanotic, complete transposition of the great arteries, pulmonary outflow tract obstruction, common mixing situations, or hypoplastic left heart syndrome. Arterial PO2 in high oxygen concentration, cardiothoracic ratio, and pulmonary vascular markings on the admission chest x-ray; respiratory rate; P-wave morphology, the electrical sign of the T-wave in lead V4R, and the presence or absence of Q-waves in leads V4R and v6 on the electrocardiogram were significant. A decision tree for the differential diagnosis of infants with suspected congenital heart disease into 5 haemodynamic groups and a group with lung disease is presented, and its predictive value is assessed.

During 1976-1988 we diagnosed sleep apnea syndrome (SAS) in 1,620 adult men and women monitored in the Technion sleep laboratories. Their age at the time of diagnosis ranged between 21 and 79 years. Fifty-seven patients (53 men and 4 women) had died by 1990, 53% due to respiratory-cardiovascular causes. The observed/expected (O/E) mortality rates, calculated for men only, revealed excess mortality of patients under 70 years old. Excess mortality was significant in the fourth and fifth decades (3.33, p < 0.002; 3.23, p < 0.0002, respectively). In patients older than 70 O/E was 0.33 (p < 0.0007). Hierarchical multivariate analysis with four fixed variables [age, body mass index (BMI), hypertension and apnea index] and four additional variables added manually one at a time (heart disease, lung disease, diabetes, apnea duration) was used to determine the predictors of death from all causes, cardiopulmonary causes and from myocardial infarction (MI). All four major variables were found to be significant predictors of mortality from all causes, in addition to lung disease and heart disease. Only age and BMI were significant predictors of cardiopulmonary deaths in addition to lung disease. Age, BMI and hypertension predicted MI deaths in addition to lung disease. These results were interpreted to suggest that SAS affects death indirectly, most probably by being a risk factor for hypertension.

Animal studies show that antimony may cause lung cancer and heart and lung disease in rodents. In exposed humans, ECG abnormalities and heart and lung disease have been reported. This mortality study of 1,014 men employed between 1937 and 1971 in a Texas antimony smelter consisted primarily of workers of Spanish ancestry (n = 928, 91.5%). Hispanics are known to smoke at much lower rates than non-Hispanics, and their lung cancer and heart disease mortality is generally low. When ethnic-specific Texas lung cancer death rates were used for comparison, mortality from lung cancer among antimony workers was elevated (SMR) 1.39, 90% CI 1.01-1.88), and we observed a significant positive trend in mortality with increasing duration of employment. When ischemic heart disease death rates from three different Spanish-surnamed populations were used for comparison, the rate ratios for mortality from ischemic heart disease were 0.91 (90% CI 0.84-1.09), 1.22 (90% CI 0.78-1.89), and 1.49 (90% CI 0.84-2.63). Pneumoconiosis/ other lung disease death rates for Spanish-surnamed men were unavailable and so calculation of rate ratios used white males as a comparison population (SMR 1.22; 90% CI 0.80-1.80). These data suggest some increased mortality from lung cancer and perhaps nonmalignant respiratory heart disease in workers exposed to antimony. However, conclusions are limited by possible confounders and the difficulty of identifying appropriate referent groups.

The application of lung transplantation to the pediatric population was a natural extension of the success realized in our adult transplantation program, which began in 1982. Twenty pediatric patients (age range 3 to 18 years) have had heart-lung (n = 11), double lung (n = 8), and single lung (n = 1) transplantation procedures. The causes of end-stage lung disease were primary pulmonary hypertension (n = 7), congenital heart disease (n = 5), cystic fibrosis (n = 4), pulmonary arteriovenous malformation (n = 2), graft-versus-host disease (n = 1), and desquamative interstitial pneumonitis (n = 1). Four (20%) patients had thoracic surgical procedures before the transplantation operation. The survival was 80% at a mean follow-up of 2 years. Immunosuppressive drugs included cyclosporine (n = 9) or FK 506 (n = 11) based therapy with azathioprine and steroids. Children were followed up by means of spirometry, transbronchial biopsy, and primed lymphocyte testing of bronchoalveolar lavage fluid. The mean number of treated episodes of rejection was 1.4 at 30 days, 0.5 at 30 to 90 days, and 1.4 at more than 90 days, and the first treated rejection episode occurred on average 28 days after the operation. Obliterative bronchiolitis developed in four (25%) of 16 patients surviving more than 100 days. Results of pulmonary function tests have remained good in almost all recipients. The greatest infectious risk was that of cytomegalovirus: one death and one case of pneumonia. Posttransplantation lymphoproliferative disease was diagnosed in two (12.5%) patients; both recovered. The most common complications were hypertension (25%) and postoperative bleeding (15%). Early results indicate that lung transplantation is a most promising therapy for children with severe vascular and parenchymal lung disease.

Heart-lung transplantation is a complex, expensive, and resource-intensive procedure. It is performed more often where there is coexistence of end-stage pulmonary disease with advanced cardiac disease that is not secondary to pulmonary hypertension (e.g., some forms of congenital heart disease, some situations with Eisenmenger's syndrome, and possibly the coexistence of end-stage heart and end-stage lung disease). Available data indicate that some disease states are associated with a higher probability of successful outcome after HLT than are others. Objectively validated and reliable patient selection criteria cannot be obtained from the current medical literature. Expert opinion provided to OHTA contained varying degrees of detail and uniformity with respect to patient selection (Tables 11 and 12). While most agree that "irreversible cardiopulmonary disease" is an indication for this procedure, there are no published data that have provided details as to how patients so designated were selected as candidates for HLT. For example, for chronic obstructive pulmonary disease (emphysema), neither expert opinion nor published studies of HLT provided data indicating the stage of the disease at which a decision to transplant is reasonable and objectively justifiable. A similar lack of detail for cystic fibrosis, bronchiectasis, pulmonary fibrosis, sarcoidosis, asbestosis, and other diseases was noted. Thus, there are insufficient data regarding transplant recipients to permit the development of objective criteria for a threshold for HLT in the various disease states. The circumstances are more problematic regarding suggested contraindications for HLT. While objective survival rates obtained from registry data indicated that survival bore little relationship to recipient age, various opinions provided to OHTA specified a maximum age for HLT candidates, ranging from under 45 years to 60 years. Adverse factors and contraindications, such as "other significant disease," "recurrent pulmonary emboli," "hepatic disease," "infection," and "insulin-dependent diabetes" were nonspecific and unsupported by published, objective evidence. More ambiguous contraindications included "psychiatric illness," "poor family support structure," "history of noncompliance with medical regimens," and lack of "emotional stability." While psychiatric, psychologic, or sociologic evaluations of potential HLT recipients undeniably have relevance to patient selection, use of such criteria should be supported at least by evidence of generally consistent application across the transplant community. Of note was the recommended requirement that the recipient possess "adequate financial resources," which implies that the benefits of HLT are not expected to be equitably provided to the public.(ABSTRACT TRUNCATED AT 400 WORDS)

We reviewed 11 pediatric cases of diaphragmatic paralysis related to nonspinal-cord injury which were managed in our Intensive Care Unit over the past 10 years. Three cases were secondary to birth trauma, 7 followed surgical procedures for congenital heart disease, and 1 occurred in association with injuries sustained in a motor vehicle accident. The paralysis was bilateral in 8 children. The diagnosis was initially suspected on clinical grounds because of respiratory distress, impossibility of weaning from the ventilator, and paradoxical abdominal respiratory movements. Confirmatory investigations included chest radiography, which revealed elevation of the affected hemidiaphragm, fluoroscopy and ultrasound, both of which demonstrated diminished diaphragmatic movement. Electromyography exhibited a failure of diaphragmatic response to phrenic nerve stimulation in 8 patients. All patients were mechanically ventilated; tracheostomy was required in 5 patients. Physiotherapy was considered a beneficial adjuvant measure. Diaphragmatic plication was attempted without success in 3 children. Seven children recovered without sequelae: Partial respiratory autonomy was achieved after an average of 2.6 months, complete autonomy after an average of 5.4 months. Two patients developed chronic lung disease; one of them remains unresponsive, and one child died following accidental extubation. We conclude that the diagnosis of diaphragmatic paralysis is predominantly clinical, and that the outcome of patients treated by adequate endotracheal mechanical ventilation is usually favorable.

The purpose of this study was (1) to ascertain whether or not the elderly utilized the health care system and did follow-up after the initial free health check-up and screening; (2) to investigate the types of chronic health problems the elderly who utilize health care had and their reasons for using the health care system; and (3) to explore related factors that influence the utilization of health care by the elderly. In this study, 484 elderly individuals were interviewed by home visits. All names were from the 11 public health clinics in Kaohsiung City, and all subjects had been diagnosed with one of the following disorders: heart disease, diabetes mellitus, hypertension, liver and biliary disorder, urinary disorder, or lung disease. Data were statistically analyzed by means of descriptive and analytical methods, %, t-test, Chi-Square test and odds ratio. The major findings of this study were as follows: (1) the utilization rate by chronically ill elderly was 80.2%. (2) elderly with multiple utilization of the health care system comprised 33.8%. (3) the variables influencing the utilization of the health care system included: perceived susceptibility, fixed physician, medical insurance, doctor's attitude, social support, community health nurse follow-up, the number of diseases, perceived severity of the illness, and attitude of health.

Myasthenia gravis (MG) is an antibody-mediated muscle disease in which any skeletal muscle can be affected. MG may produce numerous symptoms and signs. To doctors and patients, it may seem like lung disease, stroke, heart disease, or the effects of emotional stress. This article explores the "territory" between MG and diseases of the heart and lungs as well as the other neuromuscular diseases.

Lung sounds (LS) analysis is a potential source of additional objective, noninvasive and quantitative information on the status of the pulmonary system. We have examined the hypothesis that the addition of lung sounds analysis to spirometry increases the sensitivity of objective population screening, as compared to the use of spirometry alone. Questionnaires, spirometry and lung sounds were obtained in 493 active workers. Lung sounds analysis consisted of the averaged power spectra of breath sounds, measured separately during inspiration and expiration at four standard locations over the trachea and the chest-wall. Of the 493 subjects, 91 had an obstructive lung disease, including 27 with chronic bronchitis identified by a history of prolonged cough and sputum production but with normal spirometry. Twelve additional workers had a restrictive lung disease. Abnormal spirometric results were found in 74 of the patients. Abnormal lung sounds analyses were found in 54 patients, including 14 of the chronic bronchitis cases, so that the overall sensitivity of objective screening tests increased from 71% to 87% by combining the two tests. Thirty three of the subjects considered normal by evaluation of their questionnaire and spirometry had abnormal lung sounds. Of the twenty four who were re-evaluated 12-18 months after the first tests, three had developed a lung or heart disease. We conclude that the combination of spirometry and lung sounds analysis significantly increased the sensitivity of detection of pulmonary diseases by objective tests, and provided an early sign of lung disease that was not detected by spirometry alone.
