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.

An 18-year-old woman with stage IIIB Hodgkin's disease presented with minimal shortness of breath and progressed to fatal pulmonary insufficiency in five days. Biopsy and necropsy lung tissue specimens established the diagnosis of acute radiation pneumonitis. The diagnosis of radiation pneumonitis should be considered in the presence of a nonproductive cough, dyspnea, mixed interstitial and alveolar infiltrates on chest roentgenogram, negative cultures, and the characteristic findings on lung biopsy of macrophage accumulation and alveolar fibrin deposition in the face of minimal cellular infiltrate. A trial of steroid treatment may be warranted.

The aim of this study was to evaluate whether the amount of Pneumocystis carinii organisms found at fiberoptic bronchoscopy (FB) performed on HIV-positive patients correlated to the character of the P. carinii pneumonia (PCP). A consecutive series of 105 patients presented with 131 episodes of pulmonary symptoms requiring FB, and in 75 of these episodes a diagnosis of PCP was made. Specimens were stained with Giemsa and methenamine silver nitrate and the number of parasites found was given as: numerous, many, few or none. The following signs and symptoms were registered: cough, dyspnoea, fever, loss of weight, chest radiograph, haemoglobin, WBC, CD4 cell count, PO2 and HIV p24 antigen. The PCP was characterized by the clinical course: mild, moderate, severe, and by the outcome: pulmonary healthy, pulmonary insufficiency and death. No correlations between the number of P. carinii organisms and the clinical course or outcome of the PCP, the symptoms before the FB or the paraclinical examinations were found. In conclusion, the routinely obtained quantitative results of the microbiological examinations of material from the lungs were not correlated to the severity of the PCP.

The paper is concerned with pathogenetic mechanisms of cough syncope, its diagnosis, evaluation of working ability in this disease. Obesity plays a substantial role in the onset of cough syncope. The severity of pulmonary insufficiency or hypotonic dyskinesia of the tracheobronchial free are not essential for the disease course. Treatment of cough syncope should be based on therapy of pulmonary process and its complications.

A 16-year-old, 28-week pregnant woman was admitted to our hospital with multiple bone fractures caused by a traffic accident. She had massive blood transfusion because of anemia in her laboratory findings and ritodrine hydrochloride was administered because of the fear of threatened abortion. She developed a cough with bloody sputum on the 4th day after admission, and developed pulmonary insufficiency with PaO2 41.0 torr and presented bilateral diffuse infiltrates on chest roentgenograms on the next day. Swan-Ganz catheterization revealed normal pulmonary capillary wedge pressure and analysis of the lavage fluid from the patient showed an increase in the percentage of neutrophils (40.0%) and the existence of leukotriene B4 which is known to be the most potent chemokinetic and chemotactic agent for neutrophils. Her condition was considered to be permeability edema developing adult respiratory distress syndrome (ARDS) and 1 g/day of methylprednisolone was administered intravenously for 3 days, which brought about remarkable improvement of her respiratory failure. This report suggests that analysis of the lavage fluid may provide useful information for the early diagnosis of ARDS and the indications of corticosteroid treatment.

Sarcoidosis is a multisystem disease of unknown etiology that is rarely diagnosed in children. When mass screening is performed, the incidence of the disease in children approaches that of adults with similar demographics. Most childhood cases occur around ages 9 to 15 years, with small clusters of cases occurring in children under age 4 years. The disease in these two age groups has very different clinical features. Children under age 4 have a clinical triad of rash, arthritis, and uveitis. The classic syndrome in older children involves primarily lungs, lymph nodes, and eyes. In older children, constitutional symptoms (fatigue, lethargy, malaise) and pulmonary symptoms (cough, dyspnea) predominate. Mortality in childhood sarcoidosis is about 5%, with long-term sequelae in 10% to 20%. Early recognition may prevent complications such as blindness, pulmonary insufficiency, and renal impairment.

Hypersensitivity pneumonitis (extrinsic allergic alveolitis) represents a spectrum of granulomatous, interstitial, and alveolar-filling lung disorders of which farmer's lung is a classic example. A major source of offending antigens in these diseases are thermophilic actinomycetes growing in moldy vegetable matter especially Micropolyspora faeni, and members of the Thermoactinomyces genus. Acutely, hypersensitivity pneumonitis presents as cough, dyspnea and fever, with crepitant rales, leucocytosis, diffuse interstitial and alveolar pulmonary infiltrates and a restrictive-type pulmonary functional deficit. Symptoms usually begin 4 to 6 hr after exposure to large quantities of causative organic dust. Chronically, these diseases may present with the gradual onset of cough, dyspnea on exertion, fatigue, anorexia, and weight loss which may progress to pulmonary fibrosis or severe pulmonary insufficiency. While early ideas on the pathogenesis of hypersensitivity pneumonitis support the role of Type III immune complex hypersensitivity, more recent evidence attests to the important and integral role of Type IV or delayed-type hypersensitivity. It is the purpose of this review, therefore, to describe those immune mechanisms relevant to the pathogenesis of hypersensitivity pneumonitis and stress the importance of "local" pulmonary immune responsiveness.

A pediatric patient is reported who experienced fatal progressive pulmonary fibrosis as a complication of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) therapy. The patient received a cumulative dosage of 1.29 g (1.72 g/m2) over a two-year period as adjuvant therapy for a medulloblastoma. Two and one-half years after cessation of therapy, cough, tachypnea and fatigue were noted. Progressive pulmonary insufficiency developed. Pulmonary pathologic findings included interstitial fibrosis and alveolar dysplasia. Other cases of BCNU pulmonary toxicity are cited from the medical literature.

A 45-year-old Japanese woman presented with a high fever, a nonproductive coughing, and severe dyspnea, and was admitted to another hospital. During the week prior to hospitalization, she had been given Shosaikoto for treatment of liver dysfunction of unknown etiology. Mycoplasma pneumonitis was initially suspected, so she was treated with antibiotics (clindamycin and minocycline) and received oxygen therapy. Pulmonary insufficiency worsened rapidly, and she was transferred to our hospital. On admission, a chest roentgenogram revealed bilateral alveolar infiltrates predominantly in the medial lung fields. Furosemide and high-dose methylprednisolone were immediately administered, but hypoxemia increased. When the PaO2 was 55.7 Torr while the patient breathed 100% oxygen, mechanical ventilation with positive end-expiratory pressure (PEEP) was started. Arterial blood-gas values improved dramatically, and the chest roentgenogram became clear. Our diagnosis of noncardiogenic pulmonary edema is based on the chest-roentgenographic findings, infiltration of inflammatory cells as seen in two lung-biopsy specimens and bronchoalveolar lavage fluid, the lack of findings of heart failure on physical examination and electrocardiography, and the good clinical response to PEEP. A positive lymphocyte stimulation test in response to Shosaikoto implicated this non-traditional herbal medicine as an etiologic factor in the non-cardiogenic pulmonary edema. Shosaikoto has been identified as the cause of interstitial pneumonia or eosinophilic pneumonia, but pulmonary edema associated with Shosaikoto has not been previously described. This case suggests that methylprednisolone treatment may be insufficient for Shosaikoto-induced pulmonary edema, and that mechanical ventilation with PEEP is very effective.

This paper is a review of the patients with pulmonary thromboembolism hospitalized at General hospital in Teanj starting from the first case recorded in 1980 till now and 172 patients were subjects of this study. Thromboembolism was a direct cause of death in 43.7% (75 patients). Clinical and laboratory records, etiology, chest radiography, ECG data of 89 patients hospitalised and treated in the last five years were analyzed in detail. The most frequent symptoms were dyspnea and tachypnea, often accompanied with other symptoms (84.2%), chest pain (65.2%), cough (52.4%), tachycardia (40.5%), hemoptysis (25.8%). At 74% of patients with pulmonary thromboembolism a significant simultaneous increase of all examined enzymes, except CPK was found. Pulmonary insufficiency (global or partial) was found at 75% of patients. According to our results, in 57.2% of the subjects the pathologic changes on Radiography (infiltrates of the lung, with or without affection of the pleura and changed position of diaphragm) were found, and 70.9% had changes on the ECG.
