An uncommon, but lethal, toxic side effect of busulfan (Myleran) therapy for chronic myelogenous leukemia is pulmonary fibrosis. A 16-month-old male infant treated for 11 months with busulfan for chronic myelogenous leukemia is, we believe, the first case of "busulfan lung" in the pediatric age group to be reported. Progressive roentgenographic changes in the lung of a diffuse intra-alveolar and interstitial pattern were noted. The patient died after a four-day episode of cough, fever, and progressive dyspnea. At autopsy, no evidence of infection or leukemic infiltrates were seen in the lungs. Characteristic histologic findings as a result of busulfan therapy were observed in the lung and pancreas.

Ten patients developed pulmonary fibrosis after bischloroethylnitrosourea (BCNU) therapy for malignancy. This was lethal in seven patients, four of whom had no evidence of tumor at autopsy. Presenting symptoms were either the insidious onset of cough and dyspnea or the sudden onset of respiratory failure. Physical findings were unremarkable. Chest roentgenogram usually showed interstitial infiltrates. Pulmonary function studies showed resting hypoxia with diffusion and restrictive defects. This complication of therapy does not appear to be dose related and may be made more likely by the concomitant administration of cyclophosphamide. Prednisone therapy did not benefit most patients. The literature and the implications of the use of BCNU alone or in combination are reviewed.

In 196 cases of gastro-oesophageal reflux, simple or connected to a hiatal hernia or to a cardio-tuberous misplacement, the respiratory signs that are found in 1 patient out of 4, are analyzed. The nocturnal fits of coughing (39 cases, 20% of the reflux) is the most frequent sign of laryngo-tracheal aspiration of stomach content. This symptom of great diagnostic value, though neglected, should be looked for systematically. Other troubles are less frequent: bouts of recurring broncho-pulmonary infections, asthma attack, Mendelson's syndrome, pulmonary fibrosis. In absence of a patent cause, the symptoms should lead to suspect a reflux of stomach content in the airways. Similarly to oesophagitis, respiratory signs represent a complication sometimes serious, of gastro-oesophageal reflux, needing more frequently a surgical treatment of hiatal herniae or of the cardiac inefficiency.

A 73-year-old female developed pulmonary disease during treatment with chlorambucil for polycythemia vera. Cough and dyspnea were prominent symptoms. A chest roentgenogram revealed interstitial fibrosis. The diffusing capacity was markedly reduced. Pathologic findings included alveolar lining cell dysplasia, interstitial round cell infiltrates and interstitial fibrosis. Resolution of the pulmonary symptoms and partial clearing of the fibrosis on chest roentgenogram followed discontinuation of the chlorambucil and institution of steroid treatment. Chlorambucil may cause pulmonary fibrosis similar to busulfan and cyclophosphamide and this may be a potential complication of all alkylating agents.

Chronic pulmonary histoplasmosis is best regarded as an opportunist or saprophytic infection of abnormal pulmonary spaces by a fungus of very low human pathogenicity. Tissue disease results from host immune response to dispersions of soluble antigen from these focal sources. There are two distinct types of clinical and radiological response. One is an acute or subacute illness manifested by often large segmental pneumonic lesions which tend to heal and are designated as early lesions. The other, usually developing as a complication of the first, is a chronic disease marked by persistent cavitation, low gard chronic illness, and a tendency to promote pulmonary fibrosis and often progressive pulmonary insufficiency. The early lesion is a segmental interstitial pneumonitis with central areas of infarct-like necrosis often adjacent to bullous disease and often outlining prominent emphysematous spaces which appear as radiolucencies. These radiological findings are further characterized by early clearing of the interstitial components, infarct-like contraction of the necrotic zones, obliteration of much of the contained emphysematous and bullous spaces, and healing attended by considerable loss of lung volume. Symptoms are variable but tend to be mild. Malaise, fatigability, low-grade fever, aching chest pain and mild cough lasting a few days to a few weeks are usual. Symptoms are ameliorated by rest. Rest and diminished activity are recommended as treatment. Under these circumstances, 80% of early lesions heal completely and probably most of these would heal spontaneously. Any subsequent course of the disease depends on whether or nor large air spaces, adjacent to or contained within the area of pneumonitis, become infected and persist as cavities. This occurs in 20% of early lesions. Once established, an infected cavity tends to persist and to be attended by symptoms of chronic bronchitis with chronic cough and sputum, fatigability, anorexia, and weight loss. Persisting thickwalled cavities often induce gradual development of pulmonary fibrosis, particulary in the lung bases, apparently from aspiration of antigenic material. This and the accelerated obstructive bronchopulmonary disease often lead to progressive pulmonary insufficiency. The use of amphotericin B is recommended for all persistent thick-walled cavities and in some circumstances surgical resection may be indicated.

The clinical histories of 81 patients with hypersensitivity reactions to nitrofurantoin, 66 of whom had pulmonary reactions, were studied. Of all patients, 94% were women and of these, 43% were between 40 and 59 years of age. The nitrofurantoin preparation that contained vitamin c caused significantly fewer hypersensitivity reactions than the others. Acute pulmonary reactions appeared a mean of 8.7 days after the start of nitrofurantoin treatment. Typical for these were high fever, dyspnoea, cough, blood eosinophilia, bilateral pneumonic or pleuro-pneumonic infiltrations, a reduced transfer factor of the lung and, as revealed in pulmonary biopsy specimens, vasculitis, interstitial inflammation and alveolar exudation. Symptoms of subacute and chronic pulmonary reactions developed after at least 1 and 6 months of treatment, respectively. Findings of interest were anti-nuclear antibodies in serum, capillary sclerosis, interstitial fibrosis and inflammation in pulmonary tissue. Most patients with an acute pulmonary reaction recovered within 15 days, but in more than half of those with chronic reactions slight signs of pulmonary fibrosis persisted on follow-up. The findings suggest that the interstitial pulmonary changes caused by nitrofurantoin are largely the result of an Arthus-type immune complex-mediated reaction.

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.

The thyroid carcinoma is rare in children and the optimal management is rather controversial. We report a case of a 7-year-old boy who had right neck masses and proved to be papillary thyroid carcinoma after near-total thyroidectomy. Post-operative 20 mCi radioiodine-131 (I-131) ablation scan, lung metastasis was suspected but the chest X ray was normal. After being lost to follow up for 4 years, the patient returned with the complaints of cough; the chest X ray was still normal. He then received 5 treatment with low dose (30 mCi) I-131 therapy and continued thyroxine replacement. Progressive decrease both of the thyroglobulin level and the intensity of radioactivity of lung were noted. After a total doses of 193 mCi I-131 therapy, neither pulmonary fibrosis nor bone marrow suppression was seen. Although the low dose (< or = 30 mCi) I-131 therapy was recommended, it was limited for the ablation therapy of the remnant thyroid tissue. Upon consideration of economics and the convenience of not being admitted to the isolation room, the low dose I-131 therapy seems feasible for children with thyroid carcinoma with systemic disease. However, the long term efficacy needs further evaluation.

High-resolution CT (HRCT) scans were performed on 156 patients, using a bone-reconstruction algorithm, 1.5 collimation at 4 cm intervals from apex to base of the lungs and a 512 x 512 matrix. The patients appeared to have a pathologic condition on chest film, or else they presented positive clinical symptoms--i.e., cough, dyspnea, fever--and questionable/negative chest films. Since HRCT is capable of showing the secondary lobule, we employed it to study both its anatomy and the alterations that can modify its normal morphology--i.e., thickening of interlobular septa, reticular pattern, nodular pattern, high-density areas, sub-pleural lines, honeycomb pattern. HRCT findings in secondary lobules, airways, and pleura were examined. They were: lymphangitic spread of carcinoma, pulmonary fibrosis, sarcoidosis, pneumoconiosis, interstitial edema, phlogosis, bronchiectasis, emphysema, and bullae. Even though some limitations still exist due to the aspecificity of HRCT findings, the latter is the best method currently available to recognize and locate interstitial conditions and, sometimes, to make a diagnosis--e.g., of lymphangitic spread of carcinoma, interstitial edema, fibrosis, emphysema, bronchiectasis. Moreover, HRCT can accurately locate pathologic areas for lung biopsy and can be used instead of chest radiographs in the follow-up.

Mounier-Kuhn syndrome is a congenital abnormality of the trachea and main bronchi characterized by atrophy or absence of elastic fibers and thinning of muscle, which allows the trachea and main bronchi to become flaccid and markedly dilated on inspiration with narrowing or collapse on expiration or cough. The abnormal airway dynamics and pooling of secretions in broad outpouchings of redundant musculomembranous tissue between the cartilaginous rings predispose to the development of chronic pulmonary suppuration, bronchiectasis, emphysema, and pulmonary fibrosis. A broad spectrum of clinical abnormalities has been documented in Mounier-Kuhn syndrome, ranging from minimal disease with good preservation of pulmonary function to progressive disease leading to respiratory failure and death. In the appropriate clinical setting, Mounier-Kuhn syndrome is diagnosed in women from chest radiographs when the transverse and sagittal diameters of the trachea exceed 21 mm and 23 mm, respectively, and when the transverse diameters of the right and left main bronchi exceed 19.8 mm and 17.4 mm, respectively. In men it is diagnosed when the transverse and sagittal diameters of the trachea exceed 25 mm and 27 mm, respectively, and when the transverse diameters of the right and left main bronchi exceed 21.1 mm and 18.4 mm, respectively. The diagnosis can be confirmed easily by computed tomography.
