Fifty-one patients (22 male, 29 female) aged 22-60 years (mean age 41.2 years), predominantly extrinsic asthmatics, took part in this study, a follow-up to a 28-day, double-blind trial (Lal et al., Thorax 1984: 39: 809). Forty-four patients completed 12 months of treatment after a 4-week baseline; seven withdrew. A number of symptoms (e.g. coughing, wheezing, sore throat) were reported but none appeared particularly frequently; most were attributable to the technique of inhalation. After 4 weeks of treatment with nedocromil sodium (Tilade 4 mg q.i.d.), patients were encouraged to reduce use of inhaled corticosteroids (48 patients) and sodium cromoglycate (16). Inhaled bronchodilators were to be used as required and other medication was to continue as before. At the end of the study, 28 patients had stopped using inhaled steroids and 10 had significantly reduced the dosage (p less than 0.001, week 5 to end). Ten patients had stopped using sodium cromoglycate. Inhaled bronchodilator use was significantly reduced (p less than 0.001, weeks 1-8; p less than 0.05, weeks 9-12) early in the study but returned to baseline as inhaled steroid usage was reduced. Diary card assessments of wheezing and shortness of breath showed significant improvement, particularly in the early part of the study. Diary card PEFRs showed no marked changes but significant decreases, though small, were found in FEV1, FVC and PEFR on clinic visits. Clinical assessment showed improvement in the first half of the study; the differences were less marked as inhaled steroid usage declined. Final opinions of treatment effectiveness significantly favoured nedocromil sodium. This study demonstrates the acceptability, tolerability and safety of nedocromil sodium.(ABSTRACT TRUNCATED AT 250 WORDS)

Pneumocystis carinii pneumonia occurs at some point in the course of disease in approximately 85 per cent of patients with AIDS. Because of the frequency of P. carinii pneumonia and because it is readily treatable, prompt, accurate, and efficient diagnostic schemes are of extreme importance. The clinical presentation is generally characterized by fever, nonproductive cough, and shortness of breath. Such symptoms in a patient from a recognized HIV transmission category should prompt a diagnostic evaluation to identify P. carinii or other opportunistic infections. A chest radiograph usually provides an objective indication of lung disease. Pulmonary function tests, particularly the DLCO and lung imaging using 67Ga-citrate, are useful screening tests in patients with normal chest films. Examination of sputum induced by inhalation of a mist of hypertonic saline is a very useful means of identifying P. carinii. Bronchoalveolar lavage is nearly 100 per cent sensitive to the presence of P. carinii and should be performed in patients who have a nondiagnostic sputum examination. Transbronchial biopsy increases the overall yield for diagnoses other than P. carinii and should be performed in patients in whom bronchoalveolar lavage does not provide a diagnosis. Because of the effectiveness of sputum examinations and bronchoscopic procedures, open lung biopsy is rarely necessary. Measurements of circulating P. carinii antigen and antibodies are of no help in diagnosis.

A 28-year-old man developed multiple episodes of fever, cough, shortness of breath, and leukocytosis several hours after cutting live oak and maple trees. Fungal cultures of wood chips from oak and maple trees were positive for Penicillium (three species), Paecilomyces sp., Aspergillus niger, Aspergillus sp., and Rhizopus sp. Gel-immunodiffusion studies demonstrated serum precipitins to extracts of oak chips, Penicillium sp., and Paecilomyces sp., and suggested that Penicillium sp. and Paecilomyces sp. shared cross-reactive antigens that were the significant antigens in the oak chips. ELISA studies demonstrated elevated serum levels of IgG to an oak chip extract, inhibition of that ELISA by preincubation of serum with Penicillium sp., and absence of elevated IgG levels to an extract of freshly cut oak wood that had been stripped of bark to minimize mold contamination. The case analysis indicates that the patient likely had hypersensitivity pneumonitis on exposure to Penicillium sp., when he was cutting trees, and identifies cutting live trees as another occupational exposure that may cause hypersensitivity pneumonitis.

Six patients receiving CDDP, MMC, and CPM chemotherapy for adjuvant chemotherapy after a resection due to lung cancer developed interstitial pneumonia. They were re-admitted for dyspnea, shortness of breath, and dry cough from 80 to 118 days from start of their treatment. On re-admission, their chest radiographs showed reticular infiltrates, and their laboratory data showed severe hypoxemia. The pathological findings of a transbronchial lung biopsy showed a thickening of the alveolar septa. Steroid therapy resulted in a complete resolution in one patient and a partial resolution the 5 others. One year later, two patients had died, one patient remains in complete resolution, but a shortness of breath still exists in the remaining three patients. Considering the disadvantages of that shortness of breath can cause to daily life, we should be more cautious about administering antineoplastic agents for adjuvant chemotherapy to patients with a cancer in an early stage.

The effects of exposure to environmental tobacco smoke on pulmonary function were assessed in 21 subjects with asthma who claimed respiratory complaints (cough, shortness of breath, and chest tightness) on previous exposure to cigarette smoke. Exposure to mechanically produced tobacco smoke was performed in a static inhalation chamber for two-hour intervals at two distinct smoke levels (as measured by carbon monoxide, nicotine, and particulate levels). Seven of the 21 smoke-challenged subjects experienced a significant (greater than 20%) decline in FEV1 during passive exposure to tobacco smoke. One of these seven subjects was nonatopic, whereas a second subject had a negative response to methacholine challenge. The smoke-challenge responses were reproducible in all seven reactive subjects. Increasing concentrations of tobacco smoke failed to elicit pulmonary changes in previously challenged, unreactive or "smoke-tolerant" subjects. There was no association between a positive smoke challenge and the presence of serum IgE antibodies and/or a positive immediate wheal-and-flare skin test to a tobacco leaf extract. Collectively, these studies document a significant decline in pulmonary function in a substantial percentage (33%) of a population of "smoke-sensitive" subjects with asthma exposed to environmental tobacco smoke. The data also dissociate this effect from tobacco-leaf hypersensitivity.

Thirty-two workers in an electroplating plant accidently drank water contaminated with nickel sulfate and chloride (1.63 g Ni/liter). Twenty workers promptly developed symptoms (e.g., nausea, vomiting, abdominal discomfort, diarrhea, giddiness, lassitude, headache, cough, shortness of breath) that typically lasted a few hours but persisted 1-2 days in 7 cases. The Ni doses in workers with symptoms were estimated to range from 0.5 to 2.5 g. In 15 exposed workers who were tested on day 1 postexposure, serum Ni concentrations ranged from 13 to 1,340 micrograms/liter and urine Ni concentrations ranged from 0.15 to 12 mg/g creatinine. Ten subjects (with initial urine Ni concentrations greater than 0.8 mg/g creatinine) were hospitalized and treated for 3 days with intravenous fluids to induce diuresis, resulting in a mean elimination half-time (T1/2) for serum Ni of 27 hours (SD +/- 7 hour), which was significantly shorter (p less than .001) than the mean T1/2 of 60 hours (SD +/- 11 hours) in 11 subjects who did not receive intravenous fluids. Laboratory tests showed transiently elevated levels of blood reticulocytes (N = 7), urine albumin (N = 3), and serum bilirubin (N = 2). All subjects recovered rapidly, without evident sequellae, and returned to work by the eighth day after exposure.

A case of high altitude pulmonary edema with high altitude cerebral edema was reported. A young Japanese male complained of severe palpitation and shortness of breath on the third day of climbing at 3,000 m above sea level. During the next 2 d at altitude, the following symptoms occurred: cough with foamy sputum, cyanosis, and loss of consciousness. Soon after evacuation, he showed severe hypoxemia and deep coma with decerebrate rigidity; electroencephalogram showed diffuse alpha waves, indicating "alpha wave coma." Brain computerized tomography revealed brain edema, showing small compressed ventricles and diffuse low density of the cerebrum. Pulmonary edema on chest roentgenogram disappeared by the fifth hospital day, and his consciousness recovered gradually during the next 2 weeks after the admission. He was examined serially by electroencephalography and brain computerized tomography. He recovered fully, but there were transient psychological abnormalities soon after discharge and mild brain atrophy was observed by brain computerized tomography 6 years later.

162 subjects who had been exposed to isocyanates, who had developed symptoms during the exposure period, or in the evening or night and, therefore, had a history compatible with isocyanate-induced asthma, were studied with inhalation challenge testing to isocyanates (toluene diisocyanate and methylene diphenyl diisocyanate) and methacholine, because they were suspected of having occupational asthma. None of these subjects had symptomatic asthma before employment. The diagnosis of occupational asthma was delayed (duration of symptoms before diagnosis: 3.9 +/- 0.4 yrs). Isocyanate-asthma documented by a positive inhalation challenge to isocyanates was present in 57.4% of the subjects. A higher degree of airway responsiveness to methacholine was present in subjects with a positive isocyanate inhalation challenge compared to subjects with a negative challenge (Gmean and GESM: 0.407 (1.14) vs 0.942 (1.14) mg). The majority of the subjects complained of shortness of breath and cough. The low proportion of atopic subjects (21.5%) and of smokers (7.5%), and the high proportion of subjects with the late component in the asthmatic reaction (71%) appear to be common features in this disease.

Nifedipine, 30 mg/day for 4 weeks, was compared to placebo in a double-blind, randomized, crossover study, as an additional drug added to the usual treatment of 14 patients with bronchial asthma. Nifedipine did not significantly change peak expiratory flow rates or subjective symptoms like cough, sputum, wheezing, shortness of breath, or disturbed sleep. Nifedipine did not decrease the number of salbutamol rotacaps inhaled per day. Arterial blood pressure significantly decreased (p less than 0.01) after nifedipine treatment, and side effects (headache and flushing) were not uncommon. In this study, long-term treatment with nifedipine had essentially no effect on subjective symptoms at peak expiratory flow rates.
