Respiratory symptoms are a common cause of distress in patients with advanced cancer. Optimal palliative therapy requires careful assessment and the appropriate use of symptomatic measures in conjunction with specific antitumor treatments. The etiology and management of the three major respiratory symptoms, dyspnea, cough and hemoptysis, are described. The indications for antitumor treatments and surgical procedures are briefly outlined, and symptomatic treatments, including drug and nondrug measures, are discussed in detail.

Seventeen cases of pediatric malignant neoplasm with pulmonary and/or pleural lesions shown by chest radiography at initial diagnosis were reviewed and analyzed. Respiratory symptoms such as dyspnea, tachypnea, and chest pain were observed on admission in approximately one-half of them. The initial chest radiography showed pleural lesions in 7 of the 17, pulmonary lesions in 8, and both pulmonary and pleural lesions in 2. Unilateral or bilateral pleural fluids were observed in all of the seven patients with pleural lesions, and malignant cells were confirmed in the pleural fluid of all patients. The radiographic patterns of the eight patients with pulmonary lesions were solitary nodule in two, multiple nodules in two, diffuse miliary nodules in three, and diffuse honeycomb in one. Histological examination of the pulmonary lesion was performed in six patients at the initial diagnosis or after death, while in the remaining two primary or other metastatic sites were examined. The two patients with both pulmonary and pleural lesions showed multiple nodules or infiltrates with pleural fluid on chest radiography. Increased malignant cells were detected in the pleural fluid of both patients. In all cases, the lesions gradually or rapidly disappeared with multidrug chemotherapy. The review confirms the need for a combination of complete radiographic and pathological analysis at the time of initial diagnosis of malignant neoplasm in children to distinguish other causes such as infectious complications.

An evaluation of the clinical, radiological and cytohistological parameters of bronchogenic carcinoma was conducted using a sample of 25 male patients (40-80 years of age); 3 of the patients claimed they were not smokers; the rest were graded as mild/moderate/heavy smokers. The 'deep cough' method of repeated and meticulous cytologic examination of sputum samples was used to detect neoplasm. Respiratory symptoms (coughs with expectoration) were reported by 24 of the 25 cases. Bronchial biopsy in 19 cases confirmed malignancy of growth as diagnosed by bronchoscopy. Cytologic examination of sputum in 18 cases also confirmed malignant growth and illustrated the efficiency of exfoliative cytology over tissue histology. These findings support the close association between hukkah (Indian hubble bubble) smoking and lung cancer. Further research is needed however to better understand the role of hukkah smoking in the development of lung cancer.

Six patients with breast cancer developed pulmonary toxicity following mitomycin therapy. The presenting symptoms were shortness of breath and a dry cough. The radiological pictures varied from a normal chest x-ray to extensive bilateral pneumonitis. The histological findings consisted of diffuse alveolar damage progressing to interstitial pulmonary fibrosis. Corticosteroid therapy resulted in complete resolution of pneumonia in one patient. Respiratory symptoms improved in 3 patients following discontinuation of the drug. Two patients with extensive bilateral pneumonitis, who were not treated with steroids, died of respiratory failure. Mitomycin-induced lung toxicity appears to be reversible with the discontinuation of drug and the administration of corticosteroids. Lung biopsy is necessary in order to rule out other diagnoses.

Three cases with systemic rheumatic diseases who developed lung diseases compatible with BOOP were reported. Underlying diseases of these patients were: RA (1 case), SLE (2 cases). Respiratory symptoms were observed in one case such as dry cough at the time of diagnosis of BOOP. Chest radiography showed multiple infiltrates in 2 cases, bilateral reticular shadow in one case. In one case characteristic finding described as wandering shadow was observed. TBLB was done in 3 cases. Pathohistological findings were compatible with BOOP. Repeated Bacteriological examinations failed to demonstrate specific organisms implicated for lung lesions. Cytological studies of sputum and TBLB specimens were all negative for malignancy. Antibiotic agents including anti-tuberculosis drugs were not effective for pulmonary diseases. Moderate doses of prednisolone were effective in 3 cases. Although the open lung biopsy has been recommended for establishment of diagnosis of BOOP, in patient with systemic rheumatic diseases this invasive procedure is not always easily performed. Further characterizations of clinical and laboratory features are indicated for noninvasive diagnosis of BOOP.

The Japanese low ruled that the patients excreting tubercle bacilli should be treated in the isolated ward for tuberculosis. However, it is often difficult to transfer a patient with serious illness to the isolated ward with insufficient medical facilities. We investigated retrospectively the manner of the management of patients excreting tubercle bacilli in the Aichi Medical University Hospital without the isolation ward for tuberculosis. Materials were 166 patients (0.17%) out of 97,275 in-patients during 11 years since 1986 to 1996. Respiratory symptoms were observed in 114 patients (68.7% of 166 patients) on admission. The initial bacteriological examination was ordered by the attendant doctor within a week in 93 patients (81.6%) of 114 patients with respiratory symptoms. On the other hand, a half of the 52 patients without respiratory symptoms on admission were not examined for sputum bacteriology beyond a week. Anti-tuberculous treatment was started within a week after positive bacteriological results in 129 patients (77.7% of the whole 166 patients), while the treatment was not carried out or delayed in 21 patients (12.6%) because of the communication failure of the bacteriological report to the physicians. Some complications were observed in 101 patients: 21 diabetes mellitus, 20 cancers, 15 hematological disorders, 9 collagen diseases, 6 renal failures on dialysis. Serious illnesses were observed in 33 patients (20.6% of the 166 patients). Twenty-four patients (73% of the seriously ill patients) were died of renal failure, pancytopenia, cancer or respiratory failure. We considered that an isolated room for infectious tuberculosis with independent air conditioning system in a general hospital or a educational hospital was very convenient not only to the treatment of the patients with serious complications, but also to the education and training on tuberculosis for the medical student or medical stuffs.

We describe the case of a 57-yr-old female with endobronchial metastasis from stomach carcinoma. Respiratory symptoms began 3 months before the diagnosis of the gastric cancer. Chest computed tomography revealed a reticular lymphangitic carcinomatosis pattern with hilar and mediastinal lymphadenopathy. Fibreoptic bronchoscopy showed a spread submucosal infiltration which narrowed the apical segment of the left lower lobar bronchus. The biopsy specimen at that level was histologically identical to the gastric primitive cancer. To the authors' knowledge, stomach carcinoma has rarely been reported to give rise to airway metastases.

Exposures to bioaerosols in the occupational environment are associated with a wide range of health effects with major public health impact, including infectious diseases, acute toxic effects, allergies and cancer. Respiratory symptoms and lung function impairment are the most widely studied and probably among the most important bioaerosol-associated health effects. In addition to these adverse health effects some protective effects of microbial exposure on atopy and atopic conditions has also been suggested. New industrial activities have emerged in recent years in which exposures to bioaerosols can be abundant, e.g. the waste recycling and composting industry, biotechnology industries producing highly purified enzymes and the detergent and food industries that make use of these enzymes. Dose-response relationships have not been established for most biological agents and knowledge about threshold values is sparse. Exposure limits are available for some contaminants, e.g. wood dust, subtilisins (bacterial enzymes) and flour dust. Exposure limits for bacterial endotoxin have been proposed. Risk assessment is seriously hampered by the lack of valid quantitative exposure assessment methods. Traditional culture methods to quantify microbial exposures have proven to be of limited use. Non-culture methods and assessment methods for microbial constituents [e.g. allergens, endotoxin, beta(1-->3)-glucans, fungal extracellular polysaccharides] appear more successful; however, experience with these methods is generally limited. Therefore, more research is needed to establish better exposure assessment tools and validate newly developed methods. Other important areas that require further research include: potential protective effects of microbial exposures on atopy and atopic diseases, inter-individual susceptibility for biological exposures, interactions of bioaerosols with non-biological agents and other potential health effects such as skin and neurological conditions and birth effects.

Respiratory symptoms might originate sometimes in the diseases of another thoracic organ than the lungs, the esophagus, which is able to determine sufferings mimicking pulmonary diseases. The authors review a series of esophageal diseases capable of generating respiratory symptoms, as well as the criteria for differential diagnosis: Zenker diverticulum, esophageal fistula, achalasia, cancer of the esophagus, esophageal cyst and gastro-esophageal reflux disease.

Respiratory symptoms cause much of suffering in palliative care. Opioids are the first-line drugs in symptomatic treatment, and a therapeutic intervention with benzodiazepines may also be justified. If the patient does not have hypoxia, oxygen and air stream have similar effects on dyspnea. Cough reflex is attenuated with opioids, and symptoms due to respiratory secretions are alleviated with anticholinergic drugs and mucolytics. Physical therapy and methods of respiratory management are profitable in the treatment of respiratory symptoms. Radiation therapy relieves cancer-induced hemoptysis, cough, chest pain and dyspnea.
