In order to investigate the character of pulmonary complications in patients with adult T-cell leukemia (ATL), a pathological and bacteriological study was performed in 92 autopsy cases with hematologic malignancies including 17 cases of ATL and 103 autopsy cases with solid malignancies from 1981 to 1990. Among 17 cases with ATL, pulmonary complications were seen in 16 cases (94.1%); pulmonary infection in 14 (82.3%), leukemic cell pulmonary infiltration in 9 (52.9%), pulmonary hemorrhage in 5 (29.4%), pulmonary alveolar calcinosis in 2 (11.8%), and idiopathic interstitial pneumonia in 2 (11.8%). The causative microorganisms were virus in 10; 9 of which were cytomegalovirus, followed by bacteria infection in 4 cases, mainly pseudomonas aeruginosa, and fungal infection in 3, mainly cryptococcus. pneumocystic carinii and mycobacterium tuberculosis were not detected. It is suggested that patients with ATL are severely compromised with chiefly cellular immunodeficiency, and administration of sulfamethoxazole-trimethoprim and isoniazid is very effective in prevention of pneumocystis carinii pneumonia and pulmonary tuberculosis.

A 13-year-old girl with Fahr disease (infantile form) was reported. Her parents were consanguineous. Her elder sister had mental retardation and spasticity of the lower limbs, and died at 23 years of age. The patient suffered from infantile spasms at 3 month. She was bed-ridden, nonverbal, microcephalic and blind. Cranial CT revealed massive calcifications in the basal ganglia, periventricular white matter, dentate nucleus and cerebellar white matter. EEG showed a suppression-burst pattern. At 13 years, she died of pneumonia and hyperammonemia. Microscopic examination of brain showed perivascular non-arteriosclerotic ferro-calcinosis. The periventricular granules are 1-4 mu or 12 mu in diameter. This pathological change was observed only in the central nervous system above midbrain. No calcifications were found in the pituitary and the vessels of pia mater. Also a reduced ornithine transcarbamylase activity was found in the liver, which was probably not related with cerebral calcifications. Infantile form of Fahr disease is rare and may be heterogeneous in etiology. However, clinical manifestations and pathological findings were similar to those in previous reports of Fahr disease in childhood. It is one of the disorders causing infantile spasms.

The description is given of Shwachman syndrome in a male of 17, with a long anamnesis of malabsorption syndrome, granulocytopenia, repeated bronchopneumonia, somatogenic subnanism and hypogonadism. The death resulted from acute cardiovascular insufficiency. Post-mortem examination revealed exocrine pancreas hypoplasia with lipomatosis, Wirsung duct atresia, fibrocholangiocytosis and fat hepatosis, visceral anemia, delay in the maturation of granulocytes in the bone marrow, somatogenic polyglandular endocrinopathy, metabolic myocardium necrosis, calcinosis of the small arteries wall, lymphoid tissue atrophy, focal pneumonia of the upper lobe of the left lung.

The pathological findings in the lungs and related organs of 26 patients (21 female, 5 male) with systemic lupus erythematosus (SLE), with onset of disease before age 20 years, were reviewed. Several categories of lung lesions were found. Chronic interstitial pneumonitis was present in all 26 patients and was severe in 5. Acute pneumonia was present in 20, mild in 13, moderate in 2, and severe in 5. Alveolar hemorrhage, massive enough to cause death in 5, was seen in 18 patients, and pulmonary edema was found in 13. Fourteen patients had hyaline membranes indicative of acute alveolar damage (DAD), 12 had alveolitis obliterans, indicative of prior episodes of DAD, and 9 had bronchiolitis obliterans. Other parenchymal lesions were mild interstitial fibrosis in 12, alveolar hemosiderosis and alveolar overinflation in 10 each, and alveolar septal calcinosis with chronic renal insufficiency in 3. Pleural effusion, pleuritis, or pleural thickening were noted in 15 of 26, 6 of 23, and 7 of 23 evaluable patients, respectively. Vascular lesions were present in 16 as intimal thickening (9), thromboemboli (8), medial hypertrophy (6), calcinosis (3), and vasculitis (2). A previously unreported lesion was chronic (proliferative) peribronchitis, noted in 11 patients. Diaphragmatic lesions included mild variation in fiber size in 7, mild fibrosis in 2, and calcinosis in 1 of 13 evaluable patients. Correlation of the above lesions with previously described lung syndromes in SLE such as lupus pneumonitis, hemorrhagic lung disease, chronic interstitial fibrosis, lupus cor pulmonale, pleurisy, and "shrinking lung syndrome" are discussed.

The authors study the diagnosis and the prognosis in 25 children with systemic lupus erythematosus and in 22 children with dermatomyositis. The most frequent signs when the diagnosis is established are articular involvements, erythema of the face, renal disorders and the presence of LE cells. The symptoms are often misleading, which explains the long delay between the first sign of the disease and the time of diagnosis, which can vary between one month to nine years. The prognosis of this disease has improved because of modern treatments : only four patients died, three of them because of renal failure and one because of cerebral embolism, after six months, one year, three years and ten months, In dermatomyositis the most frequent signs at the time of diagnosis are skin involvements and muscular and articular symptoms. The period of time between the onset of the disease and the diagnosis is shorter : one month to four years, 19 times equal to or less than one year, because the clinical picture is quite clear. Ten times the clinical evolution lead to a complete cure, 9 times a clear improvement with sequelae was observed : retractile myelosclerosis, calcinosis and medullary compression. One patient died of intestinal ulceration and two of pneumonia aggravated by involvement of the respiratory muscles.

Pulmonary opacities following orthotopic liver transplantation (OLT) are frequent due to pneumonia, infarction, or pulmonary edema. Metastatic pulmonary calcifications are present as persistent opacities that may mimic these conditions. In a series of 91 patients who underwent OLT, chest radiographs of 77 were reviewed and pulmonary calcinosis was seen in 4 (5.2%). Pulmonary calcinosis may be due to a variety of conditions, including dystrophic calcification in damaged lung and primary or secondary hyperparathyroidism. In this series, patients with pulmonary calcinosis had significantly higher levels of serum phosphate and calcium postoperatively and had received more intraoperative platelets and other blood products containing exogenous calcium than other patients. Pulmonary calcinosis should be considered in patients following OLT when stable, nonspecific pulmonary opacities are present. CT or radionuclide studies will aid in confirming this diagnosis.

A case of tracheobronchopathia osteochondroplastica (TO) was diagnosed in a 68-year-old male with prolonged cough. A bronchoscopy revealed multiple nodular excrescences along the anterolateral wall of the trachea and main bronchi. Tissue specimens showed pronounced change of bronchial cartilage with massive mineralization diagnostic for TO. The literature on the subject is reviewed here. The aetiology and pathogenesis is unknown. The severity of TO range from no symptoms to severe dyspnoea, haemoptysis or pneumonitis. Treatment is seldom necessary. However, in severe cases, bronchoscopic removal of obstructing excrescences and surgery has been performed with therapeutic effect. Differential diagnosis of nodular excrescences includes amyloidosis, endobronchial sarcoidosis, calcificating lesions of tuberculosis, papilomatosis and tracheobronchial calcinosis. Awareness of the condition as a differential diagnosis to neo-plasms is important, to avoid unnecessary surgery or chemotherapy.

Francisella tularensis causes pulmonary tularemia and death in humans when left untreated. Here, using a novel aerosol infection model, we show that acute pulmonary Francisella novicida infection not only causes pneumonia and liver damage, but also induces dystrophic cardiac calcinosis (DCC) in BALB/c mice. C57BL/6 mice also develop pneumonia and hepatic damage, but fail to develop DCC. Development of DCC in BALB/c mice is associated with significant induction of RANKL but not osteopontin in their organs. Depletion of lung macrophages prior to infection markedly reduces pericarditis and calcification in BALB/c mice but does not increase their susceptibility to infection.
