One of the authors observed an excess of dyspnea complaints in coalminers without bronchitis, massive fibrosis or emphysema in different epidemiological surveys. An abnormally high prevalence of dyspnea complaints in coalminers has also been reported by other investigators in different countries. It seems therefore necessary to study whether the type of complaints observed in our country can be validated by appropriate functional investigations. A research on this problem is in progress in our laboratory. In this preliminary publication a review of the literature concerning the mechanisms of dyspnea is presented. Such a study was necessary in order to make an adequate choice of the functional measurements usable for our validation study.

The features of dysporia entero-broncho-pancreatica familiaris (mucoviscidosis) are described and the course of the disease over ten years is recounted. The cases are probably patients with true mucoviscidosis but in whom not all the symptoms develop in early childhood (Doerr). In the present case the symptoms only developed at the age of five years. From this time on there was increasing pancreatic insufficiency, chronic recurring bronchitis, with increasing destructive bronchitis and resulting respiratory insufficiency, dyspnoea and orthopnoea, right heart strain, sodium and chloride loss in the sweat, changes in the duodenum and the development of aganglionic megacolon.

A 23-year-old woman, who had suffered recurrent acute bronchitis, dyspnoea, and stridor, was found to have a tracheal stenosis and complete left main bronchus obstruction. Biopsy of the tumour showed an adenoid cystic carcinoma. After pneumonectomy the trachea was closed through tumour tissue. Two weeks later a right thoracotomy showed that a tumour had invaded the trachea from the carina up to 6 cm and the right stem bronchus for 1 cm. Under extracorporeal circulation 7.5 cm of the trachea and right bronchus were resected. A direct tracheal anastomosis was easy to perform. Spontaneous respiration with efficient coughing returned after five days. Unfortunately, one month later, high fever caused by a lung abscess developed, which provoked a massive haemoptysis with fatal outcome.

The disease course is described in 21 patients with low serum concentrations of alpha1-antitrypsin of the phenotype Z (genotype pi ZZ). 13 of these patients have long-standing disease characterized by bronchitis or dyspnea beginning before the age of 40 and progressing to emphysema (11 patients) and to corpulmonale (7 patients). The remaining 8 patients are children with hepatopathy characterized by prolonged jaundice at birth, persistent hepatomegaly and persistently elevated liver enzymes. In 2 children, the evolution to cirrhosis was ascertained by biopsy.

Anthracosilicosis and asbestosis are the most important types of pneumoconioses induced by inorganic dust. They produce entirely different damage to the broncho-pulmonary system. Anthracosilicosis graded B or C roentgenographically is very often accompanied by obstructive respiratory disorders; in asbestosis restrictive disturbances predominate. The question whether obstructive lesions also tend to occur remains to be solved. Dyspnoea often accompanied by bronchitis is the main clinical feature. Anthrocosilicosis is amenable to therapeutic measures which have resulted in a considerable prolongation of the life span of these cases. Improved dust control is the most rational prophylactic measure. Abstention from smoking also plays a part.

Acute massive right-sided hydrothorax is a relatively rare but serious complication of peritoneal dialysis and may be responsible for the development of dyspnea during peritoneal dialysis. The pleural fluid appears to arise from the peritoneal dialyzate based on the time of its appearance and its chemical composition. It should be included in the differential diagnosis when a patient becomes dyspneic during peritoneal dialysis along with exaccerbation of congestive heart failure, pneumonia, atelectasis, and purulent bronchitis. Its occurrence is an indication to stop the peritoneal dialysis and contraindicates further use of this form of dialysis. Treatment may be conservative or aggressive (thoracentesis) depending on the clinical condition of the patient. Etiology is poorly understood. In some cases, there may be traumatic diaphragmatic fenestrations, but the majority of cases appear to be due to less well defined communications between the peritoneal and pleural spaces.

Two epidemiological surveys were made by the same research team on the prevalence and the aetiological factors of chronic bronchitis symptoms in coalminers. The first study was made in a coalminers' community of Belgian Limburg, the other one in a representative sample of coalminers regularly at work. In both surveys an excess of dyspnea complaints was observed in comparison to the prevalence of this symptom in controls. These dyspnea complaints often presented themselves as isolated symptoms, without chronic cough or phlegm production. Dyspnea in excess could not be explained by massive fibrosis. The prevalence of the symptom was not linked, neither to the spirometric values, nor to the results of respiratory challenge tests with acetylcholine, tobacco use, or the length of exposure at the coalface. When dyspnea was associated with cough and phlegm production there was on the contrary a statistically significant relation with the spirometric values and the effect of acetylcholine. It seems therefore reasonable to explain at least partially the isolated dyspnea complaints in coalminers by specific mechanisms not related to bronchitis but resulting from the pathological lesions characteristic of simple pneumoconiosis. Complaints of cough and phlegm production appear as a rule later in the coalminer's life. In the groups taken into consideration in the study they were linked with cigarette smoking which appeared as the predominant aetiological factor for these complaints; in a subgroup a synergic action of coaldust, tobacco use and air pollution could be discussed in this respect. Notwithstanding the pathogenic independence of some dyspnea complaints versus cough and expectoration, it is quite clear that when productive bronchitis develops and causes broncho-obstruction, it may aggravate pre-existing dyspneic patterns.

A tracheal tumour was discovered by radiology in a 36-year-old man with haemoptysis, bronchitis, and dyspnoea. The tumour was situated 5 cm below the vocal cords. A frozen section of a bronchoscopic biopsy specimen confirmed it to be a neurofibroma. Resection was performed endoscopically.

73 welders were examined, who weld in an assembly room of a machine factory, mainly by an electric arc. In anamneses 60% of persons under examination notified of coughing, expectorating, dyspnoea during work, and frequent acute rhinitis. Clinical symptoms of respiratory tract disease, resulting from welding, were found in 10% of welders. Simple bronchitis, resistant bronchitis with pulmonary emphysema, pleural adhesions were diagnosed. In one case fibronodular tuberculosis was found (1%). In 8% of workers, aged 40--50, a dynamic arterial hypertension and radiological symptoms of aortosclerosis were found. 5% welders had granulocytopenia. Disturbances of the examined systems occurred in factory welders with duration of employment above 10 years.

A single-blind comparison of lymecycline and amoxycillin was performed by three general practitioners in the treatment of acute bronchitis. A total of 132 patients were treated for seven days with lymecycline (204 mg) two capsules twice daily or amoxycillin 250 mg three times daily. Symptoms and signs assessed were cough, dyspnoea, sputum volume, purulence of sputum and temperature. Both drugs brought about a statistically significant improvement. For all parameters the improvements seen with lymecycline were superior to those seen with amoxycillin although in no case did any of these reach statistical significance. However, in the case of purulent sputum those patients receiving lymecycline showed improvement which reached borderline significance (0-05 less than p less than 0-1) as compared with amoxycillin. Side-effects in the case of both drugs were negligible.
