Six cases of miliary pneumonia are reported, in which the marked increase in antibody titers showed that Mycoplasma pneumoniae was the probable cause. The clinical picture of these patients showed an acute and severe onset, with the appearance of diffuse alveolitis. The outcome of the disease depended on the time of initiation of treatment in relationship to the onset of symptoms. One case was seen to progress to fibrosing alveolitis with persistent impairment of diffusion. This observation suggests the possibility that some cases of pulmonary fibrosis of unknown aetiology may be due to previous mycoplasmal infection.

The histologic changes in transbronchial lung biopsy specimens of heart-lung transplant patients were graded during episodes of acute rejection and when patients were well. Infection was strictly excluded from all episodes studied. Grade of severity of rejection was determined by the magnitude and extent of the inflammatory infiltrate. Biopsy specimens, obtained 1 year after the initial biopsies, were examined for histologic evidence of airway submucosal fibrosis, and each patient's clinical status at this time was recorded. The biopsy material from 22 long-term survivors was studied. On 16 occasions the specimens showed no evidence of rejection (grade 0). Twelve of these sets of specimens were from clinically well patients, and four were from the patients who had clinical evidence of rejection. The other six sets of specimens, from clinically well patients, showed evidence of rejection: three grade 1 and three grade 2. One year later, the clinically well patients had normal biopsy histology without fibrosis and normal lung function. Bronchiolitis obliterans had not developed in any patient. There were 27 episodes of rejection in the 22 patients, of which 23 were confirmed histologically. Eleven sets of specimens had grade 1 acute rejection, eight grade 2, and four grade 3. Three of these patients died, and bronchiolitis obliterans was confirmed at necropsy. Lung fibrosis was more common in specimens taken after 1 year, and lung function was depressed in these patients. The histologic grading of transbronchial lung biopsy material, although still in the early stages of development, provides some predictive value to the long-term outcome of the lung transplant patient, in development of both bronchiolitis obliterans and lesser fibrotic changes.

Results of a prospective lung function study are presented for 48 patients with acute myeloid leukemia (AML) treated with total body irradiation (TBI) and bone marrow transplantation (BMT) at the Royal Marsden Hospital between 1978 and 1980. Patients with active disease or who were in remission following cytoreductive chemotherapy had mildly impaired gas exchange prior to grafting. After TBI and BMT all patients studied developed progressive deterioration of lung function during the first 100 days, although these changes were subclinical. Infection and graft-versus-host disease (GvHD) were associated with further worsening of restrictive ventilatory defects and diffusing capacity (DLCO). Beyond 100 days, ventilatory ability returned to normal and gas transfer improved, although it failed to reach pre-transplant levels. There was no evidence of progressive pulmonary fibrosis during the first year after grafting.

Although the intrafamilial transmission of infectious diseases has long been recognized, the induction of environmental disease in household contacts is being increasingly documented and requires a higher index of suspicion. An incidental radiographic finding, such as pleural thickening or calcification, or even interstitial pulmonary fibrosis in a young person without obvious occupational exposure to asbestos, should prompt the physician to clarify the parental occupational history. Likewise, unexpected evidence of lead induced abnormalities, such as elevated blood lead and/or erythrocyte protoporphyrin levels, should focus the examiner's attention on possible intrafamilial transmission, treatment, and prevention.

Diffuse pulmonary uptake of radiogallium was observed in 50 out of 510 scans (9.8%) performed in a general hospital over a period of 1 yr. Of the 50 cases, 80% had bilateral, diffuse distribution, and 20% unilateral. A variety of clinical conditions produced a similar picture on the pulmonary images. The most common cause of the diffuse uptake was infectious disease (48%) followed by infiltrative disorders (30%) and neoplastic conditions (22%). On a repeat study there was significant reduction in the intensity of pulmonary radiogallium uptake following drug therapy in three patients--sarcoidosis on corticosteroid therapy, pneumocystis carinii treated with trimethoprim and sulfamethoxozole, and interstitial pulmonary fibrosis on corticosteroids. No close correlation was observed between the underlying clinical disorder and the pattern or intensity of pulmonary uptake of radiogallium.

Lung transplantation is a successful alternative treatment for a variety of end-stage lung diseases. The first 20 lung transplants performed in Louisiana between November 1990 and July 1994 are reported from Ochsner Foundation Hospital. Transplant procedures included 1 heart-lung, 11 bilateral sequential lung, and 8 single-lung transplants in 8 males and 11 females (1 retransplantation). The average age was 38 years (range 7-60), and the median waiting time was 34.5 days (range 1-329). Indications for transplant included emphysema, pulmonary fibrosis, pulmonary hypertension, cystic fibrosis, bronchiectasis, and bronchiolitis obliterans. Overall 1-year and 3-year survival were 65.0% and 58.5%, respectively. Infection was the major cause of morbidity and mortality. Rejection episodes were observed but treated successfully in all 20 patients. Lung transplantation has proved to be a successful treatment for a variety of severely limiting and terminal pulmonary conditions for patients in our state.

Felt prepared from polyglycolide (PGA) polymer fibers was pasted with fibrin glue for prevention of postoperative pulmonary fistula, and its effects were evaluated. The subjects were 90 patients who underwent thoracotomy and were expected to develop air leakage between March 1990 and the end of 1993. The felt sheet was simply pasted in position in 67 patients, applied and fixed by suturing in 7, and sutured and pasted in 16. The duration of air leakage in the three groups were 4.6 +/- 4.1, 3.9 +/- 4.9, and 3.2 +/- 3.8 days, respectively. According to the surgical procedure employed, the duration of air leakage was 5.0 +/- 4.0 days in 41 patients who underwent pulmonary lobectomy, 5.0 +/- 4.3 days in 5 patients who underwent segmentectomym, 2.6 +/- 3.1 days in 26 cases who underwent partial pneumonectomy, and 4.9 +/- 4.0 days in the 14 cases who underwent bulla resection. In terms of disease, the leakage time was 4.6 +/- 4.2 days in patients with emphysema, 0.6 +/- 1.2 days in those with diffuse pulmonary fibrosis, 0.7 +/- 0.9 days in those with Infectious disease, 4.8 +/- 4.2 in those with lung cancer, 1.5 +/- 1.5 days in those with benign lung tumor, and 3.8 +/- 2.7 days in those with metastatic lung tumors. The procedure had no side-effect on liver or kidney function. No infection was observed even after decortication for empyema. The use of felt prevented excessive shrinking of the lung due to over-suturing. Therefore, intraoperative application of a PGA felt sheet was considered to be an effective method for prevention of pulmonary fistula.

Infection of the larynx by Candida is rare and usually accompanies lung or disseminated candidiasis. The incidence of isolated laryngeal candidiasis (ILC) is low, although it may be underestimated. We describe 2 patients with ILC confirmed during autopsy: a 45-years-old male with pulmonary fibrosis and a 4-years-old girl with acute myeloblastic leukemia. Hoarseness and dysphagia are the most common symptoms of ILC. The most effective diagnostic technique is laryngoscopy with specimen culture and/or histopathology. Specimens usually show whitish plaques on the larynx. Most ILC patients have some associated disease and/or predisposing factors, with frequent antibiotic treatment prior to the advent of candidiasis. Intravenous amphotericin B provides the most effective therapy, although other antimycotics are also useful. Early diagnosis and initiation of therapy curtail the disease and can prevent systemic dissemination.

Pulmonary fibrosis was induced following inoculation of Paracoccidioides brasiliensis conidia intranasally in BALB/c mice. Fibrosis was associated with formation of granulomas, increase in lung hydroxyproline, and sustained increases in tissue tumor necrosis factor-alpha and transforming growth factor-beta. This study suggests a role for these cytokines in generation of pulmonary fibrosis associated with chronic granulomatous infectious diseases.

Particular attention has been recently dedicated to the development of a sarcoidosis-like form in patients with common variable immunodeficiency (CVI). In sarcoidosis a 5-fold increase in the number of cells in the bronchoalveolar lavage compared with normal controls has been described and the predominance of CD4+ T cells is a common feature. In contrast to patients affected by sarcoidosis or CVI, patients with co-existence of the two diseases had a more favorable prognosis, as progressive pulmonary fibrosis occurred only in a few cases even when persistent alveolar lymphocytosis was present. Moreover, patients presenting with concomitant sarcoidosis and CVI, showed a lower rate of respiratory infections and of the evolution towards bronchiectasies in comparison with patients affected by CVI alone. The clinical evolution observed in our patients was similar with that reported in other studies and confirms their clinical features. One may speculate that the increase in the number of macrophages and T lymphocytes, as suggested by the increased cellularity in the bronchoalveolar lavage of these patients, can produce a peculiar microenvironment characterized by high levels of soluble factors (cytokines). In turn, the latter could be responsible for a more efficacious effector phase of the immune response. This may explain the reduced rate of infectious diseases and consequently of bronchiectasies observed in CVI patients.
