Abstract
The childhood respiratory consequences of very low birth weight (birth weight < or =1,500 g) are incompletely understood, especially since the introduction of recent changes in neonatal care. To assess prevalence, trends, and risk factors for respiratory symptoms, the authors followed to age 8 years a cohort of 384 very low birth weight children from six regional neonatal intensive care units in Wisconsin and Iowa who were born between August 1, 1988, and June 30, 1991. A control group of 154 Wisconsin schoolchildren was also assembled. Respiratory symptoms in the past 12 months and history of asthma ("asthma ever") were reported by parents on a questionnaire used in the International Study of Asthma and Allergies in Childhood (ISAAC). Control group prevalence resembled ISAAC prevalence worldwide and in Canada, but respiratory symptoms were twice as common among very low birth weight children. With advent of the availability of pulmonary surfactants, the prevalence of wheezing at age 8 decreased from 50% to 16% (p = 0.002) among children with bronchopulmonary dysplasia, but it increased from 14% to 38% among those with milder neonatal respiratory disease. Bronchopulmonary dysplasia, family history of asthma, smoking in the household, and patent ductus arteriosus were predictive of wheezing in the previous 12 months. Antenatal steroid therapy had a borderline-significant protective association with wheezing (odds ratio = 0.56, 95% confidence interval: 0.29, 1.1). There were interaction effects between several of the predictors.

Abstract
Prostate cancer is a complex disease to which a multitude of genetic and environmental factors contribute. Two new studies offer insights as to how the disease may arise and progress. The first describes mapping and cloning of a new candidate gene, ELAC2, whereas the second demonstrates how cooperation between Cdkn1b and Pten contribute to suppression of prostate tumors.

Abstract
This study was designed to achieve a final modeling, validation, and standardization plan for the Wisconsin cystic fibrosis (CF) chest radiographic scoring system. Sixty chest radiographs were selected to reflect a range of severity of lung pathology in children with CF. Seven experienced volunteer raters (three radiologists and four pediatric pulmonologists) from five institutions were recruited to evaluate and score the films. Analysis of scores revealed that the subcomponents of the Wisconsin system showed considerable variation from rater to rater, but reliability assessment indicated satisfactory Cronbach's alpha coefficients (0.83-0.90) among the seven raters. It was found that an additive method of total score computation is significantly more reliable (P < 0.05) than either the original multiplicative model or the traditional Brasfield scoring system. Comparison of radiologists and pulmonologists revealed a marked, systematic difference in scoring with the former group being more conservative in interpretation of abnormalities than the pulmonologists, and some of the raters showing very limited sensitivity. Quantitative chest radiology applied to children with cystic fibrosis studied long-term in longitudinal research projects requires the careful use of sensitive scoring methods and careful selection and training of multiple raters. This is particularly important since pulmonologists and radiologists can differ systematically in interpreting/scoring abnormalities.

Abstract
The object of this study was to examine the hypothesis that meter-dosed, inhaled beclomethasone administered to premature infants beginning at birth in a tapering dosage schedule over the first 12 days of life attenuates bronchoalveolar lining fluid oxyradical inflammation concomitant with modulation of bronchopulmonary dysplasia. The design of this study was an unblinded, uncontrolled phase I, pilot investigation of inhaled beclomethasone primarily examining safety and administration. The setting was a tertiary care neonatal intensive care unit. Intubated, premature infants were studied longitudinally to 36 weeks corrected gestational age. Meter-dosed, inhaled beclomethasone was administered in a tapering dosage schedule over the first 12 days of life. Endotracheal tube aspirates were collected on Days 2, 4, and 6 of life and assayed for various markers of bronchoalveolar lining fluid oxyradical stress. Infants were also assessed with regards to a number of relevant clinical variables and presence or absence of bronchopulmonary dysplasia at 36 weeks corrected gestational age. Although no differences in clinical outcome were apparent in comparing nine control infants with nine beclomethasone-treated infants, bronchoalveolar lining fluid from control infants exhibited evidence of apparent phospholipid peroxidation (enhanced polyunsaturated fatty acid consumption) on Day 2 of life compared to beclomethasone-treated infants. Significant differences were noted for percent arachidonic acid, total polyunsaturated fatty acids and ratio of polyunsaturated fatty acids, to saturated fatty acids. The ratio of monohydroxyl linolenic acid to native linoleic acid (a more specific marker of lipid peroxidation) as well as myeloperoxidase activity (a marker of neutrophil oxyradical stress) tended to be higher in the control group but did not achieve statistical significance for this small subject number study. No adverse reactions related to meter-dosed, inhaled beclomethasone were noted in the treatment group; most specifically no evidence of hypothalamic-pituitary-adrenal axis suppression was noted in either control or beclomethasone-treated infants. Meter-dosed, inhaled beclomethasone in the dosage schedule utilized was safe and appeared to moderate bronchoalveolar lining fluid phospholipid peroxidation. Small numbers of infants entered into the present investigation preclude comments on clinical efficacy because of the likelihood of a statistical type 2 error. However, additional investigations of inhaled beclomethasone initiated at birth in premature infants at risk for bronchopulmonary dysplasia, enrolling larger number of subjects and perhaps a higher dosage of beclomethasone, are warranted.

Abstract
Very low birth weight (VLBW) infants are at risk for childhood wheezing and asthma, as are children with a family history of asthma. Family history of asthma may also be associated with premature labor and, among VLBW infants, with bronchopulmonary dysplasia (BPD) and chronic lung disease (CLD) of prematurity. This study targeted all neonates with birth weight <1,501 g who were admitted to seven perinatal centers in Wisconsin and Iowa between August 1, 1988 and June 30, 1991. Comprehensive information was collected for 723 of the 1,007 30-day survivors, and for 106 full-term controls. A representative subgroup of 257 VLBW children was contacted at age 5 years to ascertain bronchodilator and/or steroid use and diagnosis of asthma. Some evidence of an association between family history of asthma and premature birth was found, but it was not associated with neonatal BPD/CLD or BPD/CLD severity. Among BPD/CLD indicators, radiographic evidence of BPD at age 25-35 days was most strongly associated with bronchodilator use up to age 2 years (odds ratio (OR) = 10.1, 95% confidence interval (CI) 4.07-25.2) and with asthma between ages 2 years and 5 years (OR = 4.83, 95% CI 2.18-10.7). Among children without radiographic evidence of BPD, family history of asthma was associated with childhood asthma and bronchodilator use.

Abstract
Criteria in common use for the diagnosis of chronic lung disease of prematurity or bronchopulmonary dysplasia in the neonatal period have not been sufficiently compared and validated against indicators of later respiratory complications. In this study of all 680 infants < or = 1500 gm birth weight admitted to six perinatal centers August 1, 1988, to July 31, 1990, 524 were alive and had no major congenital anomalies at 5 years old. Of 419 who had given permission to release their names and addresses, 272 were located and participated in a follow-up study. The following diagnostic criteria for bronchopulmonary dysplasia and chronic lung disease of prematurity were used during the initial hospitalization: (1) use of supplemental oxygen on day 30 of life, (2) a comprehensive bronchopulmonary dysplasia severity score applied at 25 to 35 days of life developed by a clinician panel to adjust for practice variation in ventilatory support and blood gases, (3) use of supplemental oxygen on day 30 of life with radiographic evidence consistent with bronchopulmonary dysplasia between days 25 and 35 of life, (4) radiographic evidence consistent with bronchopulmonary dysplasia alone, and (5) use of supplemental oxygen at 36 weeks' postconceptional age. These criteria were assessed against use of bronchodilators or steroids during the first 2 years of life, diagnosis of asthma, and hospitalizations for respiratory causes up to age 5. Although all criteria were significantly associated with all the outcomes, radiographic evidence was most predictive. These results indicate that, during a period when 21% of neonates were exposed to antenatal steroids, 24% received surfactant and 9% received postnatal corticosteroids, radiographic evidence was more predictive of long-term respiratory outcome than other commonly used criteria.

Abstract
We examine the relation of key neonatal outcomes to pregnancy complications and to the use of antenatal steroids and investigate whether there is evidence of recent change in this relation. Complete information on pregnancy and neonatal course was available for 749 out of 949 singleton births without major congenital anomalies below 1501 g admitted to seven regional neonatal intensive care units between August 1, 1988 and June 30, 1991. Mortality was highest in infants born after labor with spontaneous rupture of fetal membranes of less than 24 hours duration (odds ratio [OR] = 1.6, 95% confidence interval [1.0, 2.6]). Spontaneous rupture of membranes of over 24 hours duration was associated with decreased risk of respiratory distress syndrome (OR = 0.42, [0.28, 0.64]) and decreased risk of patent ductus arteriosus (OR = 43, [0.28, 0.66]). Pregnancy induced hypertension was associated with increased risk of respiratory distress syndrome in those born at less than 20 weeks' gestation (OR = 6.0, [2.0, 17]). Labor with or without rupture of membranes of short duration was associated with increased risk of intraventricular hemorrhage (OR = 1.9, [1.2, 2.5]). These associations were not different in early versus late time periods of the study. Antenatal steroids were associated with dramatically reduced risk of mortality (OR = 0.20, [0.09, 0.50] ), respiratory distress syndrome (OR = 0.52, [0.32, 0.85]), and intraventricular hemorrhage (OR = 0.37, [0.21-0.65]).

Abstract
OBJECTIVE To assess the impact of recent changes in neonatal intensive care on the mortality and morbidity of very-low-birth-weight neonates (< 1501 g). DESIGN Prospective cohort study. SETTING Six neonatal intensive care units in Wisconsin and Iowa. PARTICIPANTS All very-low-birth-weight neonates who were admitted to the neonatal intensive care units the year before the availability of exogenous surfactant (n = 333), during the investigational new drug protocol for synthetic surfactant (Exosurf) (n = 347), and after the release of synthetic surfactant (n = 356) (designated as periods 1, 2, and 3, respectively). INTERVENTIONS None. MAIN RESULTS The percentage of neonates receiving exogenous surfactant in the three periods was 3%, 37%, and 56%, and the percentage receiving antenatal steroids was 12%, 17%, and 27% (P = .0001 for increase in both modalities). The percentage of neonates dying in the three periods was 23%, 14%, and 19% (P = .05 for downward trend). The percentage of neonates with intraventricular hemorrhage decreased in the subgroup weighing between 700 and 1350 g (35%, 28%, and 24%) (P = .04) and increased in the subgroup weighing below 700 g (8%, 41%, and 45%) (P = .03). The percentage of neonates with bronchopulmonary dysplasia increased from 21% to 36% between periods 1 and 2 (P = .003) and decreased to 27% (P = .04) in period 3. Antenatal steroid use was strongly associated with the decrease in intraventricular hemorrhage (odds ratio, 0.35) and mortality risk (odds ratio, 0.20). CONCLUSIONS Several developments in care have contributed to changes in mortality risk, incidence of intraventricular hemorrhage, and the severity of respiratory disease in very-low-birth-weight infants.

Abstract
OBJECTIVES To develop a simple, clinically meaningful radiographic score for bronchopulmonary dysplasia (BPD). To investigate its reliability, validity, and usefulness and to compare it to the Edwards score. WORKING HYPOTHESIS Our radiographic scoring of BPD is reliable, correlates with respiratory support, and provides a necessary standardization in comparing severity of respiratory disease between hospitals. STUDY DESIGN Prospective cohort study. PATIENT SELECTION The study included all neonates (n = 366) with birth weight below 1501 g admitted to 7 neonatal intensive care units, who had chest radiographs taken at age 25-35 days. METHODOLOGY A simple radiographic scoring system was developed. Scores ranging from 0 to 6 were assigned based on standard radiographs and descriptors of degree of abnormality. All radiographs taken between days 25 and 35 of age (n = 1087) were graded by a radiologist and a neonatologist. Radiographs from a stratified random sample of 37 neonates (10%) were also scored by the method of Edwards (n = 128 radiographs). A respiratory support index was constructed for days 25-35 and correlated with the radiographic score. RESULTS Between-reader correlation was r = 0.87 for our score and r = 0.88 for the Edwards score. The two scores correlated with each other at r = 0.94. The respiratory support index correlated with our radiographic score at r = 0.75 overall, and r = 0.56 to 0.88 within hospitals. Higher postnatal corticosteroid use was found at the hospitals with the lower correlations. CONCLUSIONS Our radiographic scoring is reliable, valid, and gives results similar to the Edwards score. Radiographs play a standardizing role in assessing severity of BPD between hospitals.

Abstract
A new clinical scoring system for patients with cystic fibrosis is needed because of recent advances in diagnosis and treatment which have changed the course of this disease. Chest radiograph scoring is the best objective measure of pulmonary disease for longitudinal studies beginning with infants; however, based on pilot studies, previous scoring systems are not sensitive enough in discriminating between degrees of mild lung disease. Therefore, a new radiographic scoring system was developed with the goal of achieving both sensitivity and reproducibility. This objective was pursued by applying multiattribute utility theory, using a panel of interpreters with expertise in cystic fibrosis radiology, and employing mathematical modeling techniques to weight the various components. The system was developed and validated in three phases including comparison to the Brasfield method of quantitative radiology. The data demonstrate that the new system can be applied reliably and conveniently to generate reproducible scores of pulmonary disease severity. Evaluation of the scores by four independent raters using chest radiographs from 61 patients at an average age of 8.37 years revealed good agreement with a .714 Kendall coefficient of concordance. Assessment of serial changes over time was performed using a group of 176 chest radiographs from 25 patients ranging from 4 weeks to 6 years old; this showed that the Wisconsin system generates score differences that are greater in magnitude with disease progression compared with the Brasfield method. Therefore, the new method is more sensitive to progression of mild disease and should be superior to prior radiographic scoring systems for evaluating therapies designed to modify the early course of disease. The Wisconsin system is designed to be useful in longitudinal clinical studies involving young children with cystic fibrosis and is capable to detecting progression from normality to mild lung disease.

Abstract
All neonates (n = 581) with birth weights less than 1501 gm admitted to seven neonatal intensive care units in Wisconsin and Iowa were candidates for a study aimed at the multivariate assessment of risk factors for chronic lung disease while controlling for baseline severity of respiratory disease. Data from 361 neonates were analyzed for all risk factors except fluids; only neonates weighing less than 1200 gm were included (n = 220). Information on traditional risk factors for chronic lung disease was abstracted. A total of 110 (30%) of the analyzed neonates were oxygen dependent on day 30 of life. The following baseline factors were associated with increased risk of oxygen dependence in a joint multivariate model: lower birth weight (odds ratio 1.4/100 gm), higher baseline severity score (odds ratio 2.7/doubling at 32 weeks gestational age), lower gestational age (odds ratio 2.4/week at severity 0), Apgar score at 1 minute (odds ratio 1.6/2 points), male gender (odds ratio 1.9), and nonblack race (odds ratio 2.2). After adjustment for all baseline factors, patent ductus arteriosus, ventilator pressure at 96 hours, oxygen at 96 hours, and fluid intake were associated with oxygen dependence. Neonates with a low baseline severity score who remained oxygen dependent had a higher intake of fluid relative to output, whereas neonates with a higher baseline severity score had higher fluid intake and output. Lack of weight loss was associated with increased severity but not with oxygen dependence. The results of this study generally confirm the significance of previously reported risk factors for chronic lung disease in a multivariate setting but show that risk factors may not have the same impact in neonates with different baseline severity.

Abstract
An accurate description of the population at risk for neonatal chronic lung disease is clearly of prime importance for comparative studies and the planning of interventions. Attempts to explain variations in chronic lung disease rates in such studies have been compromised by lack of a way of estimating the severity of the initial pulmonary disease as a risk factor. Therefore, a severity index was developed for use in very low birth weight (less than 1501 g) neonates. Special emphasis was placed on applicability of the index in the multicenter observational setting. Development followed a clinician panel approach, with the resulting index designed to capture clinical judgment of severity. The index was validated prospectively on neonates in a neonatal intensive care unit, and retrospectively using charts from nine hospitals nationwide. Correlations of the index with clinical judgment in the two samples were .95 and .93, respectively. In an additional validation the index combined with birth weight correctly predicted oxygen dependence status at 30 days in 36 of 42 neonates consecutively admitted to five neonatal intensive care units (P = .002). Birth weight and the severity index contributed about equally to the prediction, and therefore they seem to represent partly independent components of baseline propensity for prolonged oxygen dependence.

Abstract
Mammography is important in women who elect lumpectomy and radiation therapy for breast carcinoma: to record the preoperative state, to assess the completeness of resection, and to detect recurrences and second primaries. Mammography of these patients, however, is difficult since surgery and irradiation may cause changes simulating carcinoma. This article describes the findings in the postsurgical and irradiated breast and the difficulty of differentiating the changes from recurrent carcinoma. It also illustrates the findings in recurrences and second primaries.

Abstract
Bronchomalacia has not previously been described in association with Larsen syndrome. In this article, three children with Larsen syndrome are reported. All three patients have tracheomalacia, and one of them has diffuse bronchomalacia diagnosed at flexible fiberoptic bronchoscopy. The patients' symptoms of airway obstruction include stridor, cyanosis, apnea, and recurrent pneumonias. Recognition of these abnormalities may allow the institution of supportive therapy.

Abstract
Nine of 56 patients with mucopolysaccharidoses (MPS) showed small tracheal diameters on their frontal chest radiographs. Autopsy of an MPS I-H (Hurler disease) patient demonstrated that the small calibre was secondary to deposition of glycosaminoglycan (mucopolysaccharide). Autopsies of two patients with other storage diseases, one with geleophysic dysplasia and one with mucolipidosis II, also exhibited compromise of their airways because of storage material accumulation.

Abstract
To study the effects of grain dust exposure, we compared respiratory parameters between 310 grain handlers and 237 city workers of comparable age, height, weight, and smoking habits. Both populations resided and worked in the same geographic area of the United States. Information was obtained by questionnaire, interview, and examination. Pulmonary function tests included FEV1, FVC, FEF25-75, Vmax50, CV, delta N2/L, and DLCO. The prevalence of acute work-related and chronic respiratory symptoms, of auscultatory bronchi, and of airways obstruction (FEV1/FVC less than 0.7) were significantly higher (p less than 0.05) in grain handlers than in control subjects. The mean values of all lung functions except CV, delta N2/L, and DLCO were significantly lower in grain workers than in control subjects. The effects of smoking and grain handling on symptom prevalence and lung functions adjusted for age and height, analyzed by logistic regression model, were highly significant (p values ranged from 0.00001 to 0.5) and independent. The odds of having chronic bronchitis or wheezing at work were, respectively, increased 4.4-fold and 4.8-fold by grain handling and by 2.9-fold and 1.9-fold by smoking. Grain handling increased the odds of having airways obstruction 2.6-fold and smoking increased it 2.7-fold. We conclude that grain handlers have a higher prevalence of chronic bronchitis and other respiratory symptoms than do comparable workers who do not handle grain. The effect of grain dust exposure on symptom prevalence is usually greater than that of smoking. Grain handling has an adverse effect on lung function that is of the same or smaller magnitude than that of smoking.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
It is increasingly important for mental health occupational therapists to monitor trends in reimbursement for mental health care in order to ensure adequate and equitable coverage of occupational therapy services. Federal and state funds for treatment of mental illness are being divided among an increasing number of mental health professionals. Private insurers are limiting direct coverage to those services that can supply cost and utilization information. This paper reviews present coverage for occupational therapy in mental health programs. Collection of efficacy and cost benefit data, establishment of separate billing procedures, and participation in the formation of public policies for treatment of the mentally ill should be primary activities pursued by occupational therapists to expand coverage of occupational therapy services in psychiatric settings.

Abstract
Two children, aged 3 months and 4 years, respectively, were treated with ten weeks of amphotericin B for culture proved pulmonary blastomycosis. Organisms were easily demonstrated in nasopharyngeal or sputum specimens on admission. Although organisms were present until the 12th and 19th days of therapy, respectively, they were viable through only the seventh and 12th days of therapy. Both patients had thrombophlebitis, anemia, neutropenia, hypokalemia, fever, and vomiting develop during therapy. The less toxic drug hydroxystilbamidine isethionate, given for only 17 to 30 days, has been used successfully in at least six previously reported cases. Long courses of amphotericin B therapy may not be necessary for the treatment of pulmonary blastomycosis in selected children.

Abstract
Pulmonary functions of patients with allergic bronchopulmonary aspergillosis were studied during an acute episode (n = 6); during a mean follow-up period of 44 months (range four months--14.8 years) (n = 16); and for any correlation between duration of ABPA and asthma with the total lung capacity (helium dilution), 1 second forced expiratory volume (FEV1), vital capacity, 1 second forced expiratory volume-forced vital capacity ratio (FEV1:FVC per cent) and diffusing capacity of carbon monoxide (DL:CO) (single breath) for the entire group (n = 22). All patients were treated with corticosteroids (intermittent or continuous) and bronchodilators. For the 16 patients, slopes using linear regression analysis were determined from the function as per cent predicted versus time in months from diagnosis and then analyzed for significance. Significant functional loss was shown in three of 16 patients for FEV1, two of 16 patients for vital capacity, one of 16 patients for FEV1:FVC per cent, none of 10 patients for DL:CO and one of 10 patients for total lung cital capacity, FEV1:FVC per cent and the duration of asthma or allergic bronchopulmonary aspergillosis was found by multiple regression analysis correcting for age and smoking (mean 4.24 years; range 0.3 to 14.8 years). Roentgenographic criteria and blood eosinophilia were used to define a "flare" of allergic bronchopulmonary aspergillosis. The six patients during a flare showed a significant reduction in total lung capacity (P less than 0.001), vital capacity (P less than 0.05), FEV1 (P less than 0.01) and DL:CO (P less than 0.001) which uniformly returned to baseline values during steroid therapy. The FEV1:FVC per cent remained unaltered. These findings, contrary to suggestions in the literature, indicate that in the majority of our patients there was no significant progressive functional deterioration after diagnosis. However, during acute episodes of allergic bronchopulmonary aspergillosis, transient reduction of volumes and DL:CO were uniformly present.

Abstract
Two unusual cases of congenital partial eventration of the left diaphragm in young infants are described. In both cases the entity appeared as a space occupying lesion in the left anterior chest and was initially thought to represent pericardial cyst, mediastinal tumor, or cardiac enlargement. The left lobe of the liver occupied the eventration in both cases; one was proven at surgery, and the other was documented with a radionuclide liver scan. The radiographic features of eventration are discussed and the role of radionuclide liver scanning in infants with chest masses is emphasized.

Abstract
A survey of 300 grain elevator workers revealed that 77 per cent complained of eye symptoms; 64 per cent, of nasal symptoms; and 88 per cent, of one or more respiratory symptoms on exposure to airborne grain dust. Symptoms on exposure were independent of age and length of employment. Cough and wheezing on exposure were more common among smokers than nonsmokers (P less than 0.025). Nineteen per cent of the workers had had episodes of grain fever. The prevalence of chronic bronchitis was 37 per cent (42 per cent of smokers and 30 per cent of nonsmokers). Wheezes on auscultation were found in 23 per cent. Measurements of lung ventilatory function, as well as diffusing capacity, correlated significantly with age and smoking habits, but not with length of employment. Thirty-seven per cent of the workers had an abnormal mean forced expiratory flow during the middle half of the forced vital capacity (47 per cent of smokers and 13 per cent of nonsmokers), and 34 per cent had an abnormal maximal expiratory flow after exhalation of 50 per cent of the forced vital capacity (40 per cent of smokers and 13 per cent of nonsmokers), whereas only 13 per cent had an abnormal ratio of 1-sec forced expiratory volume to forced vital capacity. There was no correlation between precipitins to fungi, bacteria, grain, or grain dust antigens and acute or chronic respiratory symptoms, lung function, or grain fever. There was, however, a significant correlation between cutaneous reactivity to grain dust and wheezing on exposure (P less than 0.02). Abnormal flows at low lung volumes were more common among cutaneous reactors to common allergens. We concluded that exposure to airborne grain dust can cause acute inflammatory reaction to the exposed mucosa, and it is highly probable that grain dust contributes and, in some cases, causes chronic airway disease.

Abstract
To evaluate the usefulness of precipitin tests as a screening method to detect hypersensitivity pneumonitis, we compared persons with precipitins to organic antigens with precipitin-negative subjects from the same population of 1,072 office workers participating in a health survey examination. Thirty-three of the 53 persons with preciptins to Micropolyspora faeni, Thermoactinomyces vulgaris, T. candidus, pigeon serum, aspergillus, alternaria, pullularia, penicillium, cephalosporium, trichoderma, and phoma were matched according to age, sex, height, and smoking habits with precipitin-negative subjects. The subjects completed a self-administered standard questionnaire, they were interviewed and examined, chest radiograms were taken, and pulmonary functions were evaluated at rest and during mild and moderate exercise. No significant differences were found between the 2 populations in any of the pulmonary function measurements. In addition, clinical and radiologic evidence failed to distinguish between the 2 groups. No cases of hypersensitivity pneumonitis were found. In this population, precipitins had no apparent relationship to long disease. The frequency of precipitins was considerably higher than the frequency of hypersensitivity pneumonitis. We concluded that the detection of hypersensitivity pneumonitis in population surveys attempting to establish prevalence of the disease cannot be accomplished by the simple analysis of serum precipitating antibodies but requires, in addition, a more complex analysis of historical, radiologic, and immunologic data.
