Dendriform pulmonary ossification is a rare entity associated with chronic lung disease that is almost invariably discovered as an incidental finding at autopsy. Antemortem chest roentgenograms of patients with dendriform pulmonary ossification are often interpreted as pulmonary fibrosis and/or bronchiectasis. Radiographic and pathologic findings in two cases are described herein.

Pulmonary alveolar proteinosis is a relatively rare, diffuse lung disease for which whole lung bronchopulmonary lavage is an effective treatment. The possibility of spontaneous remission also exists, but few actual cases have been described. This report describes a 56-year-old woman in whom pulmonary alveolar proteinosis was diagnosed 18 years earlier ...
Gonzalez E B - - 1987
We studied a patient with relapsing idiopathic chronic eosinophilic pneumonia. Each one of four attacks observed during a 4-year period was characterized by dyspnea, wheezing, peripheral blood eosinophilia, elevated serum IgE levels, and pulmonary infiltrates. Glucocorticoid therapy caused prompt resolution of symptoms and disappearance of blood eosinophilia and pulmonary shadowing. ...
Sastre J - - 1987
We describe a patient with pulmonary ceroid histiocytosis. Skin pigmentation, chest x-ray film and laboratory findings were normal. Only pulmonary function tests were abnormal (TLC = 63 percent, DLco = 52 percent). Based on these functional data, the patient was submitted to a lung biopsy by thoracotomy. Brown pigmented histiocytes ...
Stentoft J - - 1987
A 26-year-old woman with extra-pulmonary Wegener's granulomatosis was treated with cyclophosphamide for 3.25 years, cumulated dose of 91 g. Six months before cessation of therapy discrete radiological signs of apical fibrosis appeared. The changes were progressive regardless of discontinuation of cyclophosphamide and led to severe restrictive ventilatory defect.
Ofner S - - 1987
We evaluated the effect of betaxolol on the pulmonary function tests of nine patients with glaucoma and chronic obstructive pulmonary disease (COPD) requiring beta-blocker therapy. The results of pre-treatment pulmonary function tests were compared to results after two weeks of betaxolol therapy. The mean ratio of forced expiratory volume in ...
Westcott J L - - 1986
Postmortem examination of the lungs of 12 patients with end-stage pulmonary fibrosis revealed the frequent (nine of 12) presence of bronchiectasis. The segmental and subsegmental bronchi were dilated, tortuous, and had a convoluted appearance that resembled a string of pearls. Bronchiectasis was confined to areas of advanced fibrosis. When fibrosis ...
Maharaj B - - 1986
An indian woman with pulmonary alveolar proteinosis whose symptoms, chest radiograph and pulmonary function tests remain unchanged 3 years after diagnosis is described. A brief discussion of this rare disease is also presented.
Gonzalez-Rothi R J - - 1986
To investigate the function of alveolar macrophages (AM) and the mechanisms of impairment in pulmonary alveolar proteinosis, we established in culture AM from three patients and from eight normal nonsmokers and assessed phagocytosis and phagolysosome fusion by the acridine orange assay with live yeast as the phagocytic challenge. Alveolar macrophages ...

Retroperitoneal fibrosis is associated with Riedel's thyroiditis, in which an unexpectedly high proportion of the plasma cells have been reported to contain IgA and lambda light chains. It has been suggested that retroperitoneal fibrosis and the inflammation and fibrosis in thick-walled abdominal aortic aneurysms are caused by a hypersensitivity reaction ...
Berry D - - 1986
We used the model of bilateral cervical vagotomy of adult rabbits to cause respiratory failure characterized by pulmonary edema, decreased lung compliance, and atelectasis. We documented an 18-fold increase in radiolabeled albumin leak from the vascular space into alveolar washes of vagotomy vs. sham-operated rabbits (P less than 0.01). Despite ...

There is conflicting and incomplete information in the literature on the pulmonary reaction which can occur following treatment of schistosomiasis. We examined the pulmonary function, bronchoalveolar lavage profile, and lung histopathology of a patient with pneumonia and peripheral eosinophilia following oxaminquine chemotherapy for intestinal Schistosoma mansoni infection. Spirometry revealed restrictive ...
Jacobsen L E - - 1986
In patients with cystic fibrosis, plain chest radiographs may suggest the presence of bronchiectasis, bronchoceles, hilar adenopathy, or pulmonary arterial hypertension. We compared computed tomography (CT) with conventional chest radiography in 12 patients. CT clearly reveals the cause of increased linear markings, nodular lesions, and enlarged hila as seen on ...
Yoshimura H - - 1986
High-resolution computed tomographic scans of 19 patients with pulmonary asbestosis revealed a subpleural curvilinear shadow (SCLS) parallel to the inner chest wall in the lungs of 15 (78.9%) patients. Most (46.7%) SCLS measured greater than 5 cm but less than 10 cm in length and occurred less than 1 cm ...
Lyons D J - - 1986
Ethanol is claimed to have a specific damaging effect on the lung and to be at least partially responsible for pulmonary dysfunction in alcoholics. Adequate allowance for the damaging effects of cigarette smoking has not, however, been made hitherto. Pulmonary function studies were undertaken in 27 alcoholic subjects. Although there ...
Basset F - - 1986
The histopathologic and ultrastructural features of intraluminal organizing and fibrotic changes were studied in open lung biopsies and autopsy specimens from 373 patients with interstitial lung disorders, including hypersensitivity pneumonitis (n = 44), idiopathic pulmonary fibrosis (n = 92), collagen-vascular diseases (n = 20), chronic eosinophilic pneumonia (n = 10), ...
Holden W E - - 1986
In this report we describe a young woman with idiopathic thoracic scoliosis associated with marked lordosis. Pulmonary function, tested in the upright standing position, showed a restrictive pattern of impairment. However, when the patient was tested in the forward-flexed position, pulmonary function was dramatically improved. Following surgical partial correction of ...
Cazzadori A - - 1986
A patient with atrial premature depolarizations developed pulmonary toxicity during long-term treatment with amiodarone. The clinical features were cough and dyspnea. Pulmonary function tests showed a restrictive defect and severe impairment of gas transfer. Diffuse interstitial and intra-alveolar shadows were noted on chest X-ray. Lung specimens obtained by transbronchial biopsy ...
Poirot G - - 1986
Based on the dissection of 30 hemi-mandibles, the authors report a study of the inferior alveolar artery in its intraosseous course. On morphologic considerations they propose a classification of the collaterals into two groups: the principal collaterals destined for the teeth and the bony alveolar tissue and the secondary collaterals ...

A cohort of 1,117 asbestos insulation workers was established in 1963 and has been prospectively followed since then. Chest X-ray abnormalities detected at the initial medical examination, and interpreted according to the International Labour Office Classification of Radiographs of Pneumoconioses are reported in this paper. The prevalence of all radiographic ...
Neukirch F E - - 1985
Epidemiologists using pulmonary function tests agree that a number of factors have to be taken into account. In a study carried out among 912 men aged 22 to 54 we found that those having a common cold and cough on the day of examination had lower pulmonary function values. So ...
Tuder R M - - 1985
Lungs of twelve patients with chronic paracoccidioidomycosis (Pb) were studied in an attempt to understand the pathogenesis of the pulmonary disease. Ribbons of the lung parenchyma including the hilar region and directed towards apical, basal and lateral regions were subdivided into sections from the hilar, intermediate and peripheral segments. The ...
Fischbein A - - 1985
Interstitial pulmonary fibrosis (IPF) is often of uncertain etiology and is therefore named 'idiopathic' pulmonary fibrosis. Some occupational exposures, however, are known to cause interstitial fibrosis, asbestos and silica being well-known examples. We present clinical and pathological findings of a case with IPF and the results of microchemical analysis of ...
Lilis R - - 1985
This report describes a patient who developed acute chemical pneumonitis following overexposure to metal mercury vapor. The exposure occurred in a gold extraction facility where a gold-mercury amalgam was heated in a confined area. Prompt treatment with penicillamine and corticosteroids was instituted; radiologic pulmonary infiltrates disappeared within a week, but ...
Tablan O C - - 1985
An unusual case of chronic interstitial fibrosis that developed as a sequela of Mycoplasma pneumoniae pneumonia is described. Predominant manifestations included progressive exertional dyspnea, shortness of breath, persisting lung infiltrates, low lung volumes, and low pulmonary diffusing capacity. Open lung biopsy one year after the acute stage of mycoplasma pneumonia ...
Galko B - - 1985
The association between digital clubbing and idiopathic pulmonary fibrosis has been well established; however, the simultaneous occurrence of hypertrophic pulmonary osteoarthropathy and interstitial fibrosis, in the absence of neoplastic disease, has only been described in two case reports and was not mentioned in any of 336 patients described in several ...
Regadera J - - 1985
Autopsy specimens of the testes, epididymides, and spermatic cords from 20 adult young and 60 elderly men were studied by angiographic and histologic techniques. Testicular alterations in elderly men were correlated to the degree of aortic atheromatosis. Elderly men without manifest atheromatosis showed no lesions. Elderly men with slight atheromatosis ...

The polymorphonuclear leukocyte (PMN) may play an important role in the pathogenesis of emphysema. Cigarette smoking is associated with the accumulation of PMN in the lung as determined by bronchoalveolar lavage. We enumerated alveolar wall PMN on histologic sections from lungs of humans and hamsters with and without cigarette smoke ...
Hasleton P S - - 1985
A series of 20 cases of radiation bowel disease (RBD) was studied qualitatively and the arterial changes were studied quantitatively. A control series of 45 cases was studied. In the control cases there were positive correlations between the medial thickness of all vessels studied and the diastolic blood pressure as ...
Cohn J R - - 1985
A patient with longstanding mild asthma presented with a several month history of almost continuous wheezing. Pulmonary function tests suggested large airway variable intrathoracic obstruction. At bronchoscopy, she was found to have severe bronchomalacia limited to the left main bronchus. There was almost complete obstruction of that airway during forced ...
Munakata M - - 1985
