Spirography was normal in 8% of the cases; a mixed ventilatory impairment, with an obstructive prevalence of variable extent, was present in 2/3 of the cases. Pharmacodynamic tests in 353 subjects showed a frequent non-specific bronchial sensitivity (34.2% of the whole group). Hypoxaemia (PaO2 below 75 mmHg) with normo- or hypocapnia was observed in 379 patients; hypercapnia was relatively uncommon (9.9%) and occurred mainly in bronchitic patients. The breath holding CO lung transfer test was very often disturbed, as the diffusing capacity (DLCO) was below the predicted value in about 80% of the population. Radiofunctional comparisons were carried out in an homogeneous group of 212 subjects. The data clearly demonstrate that functional abnormalities were not exclusively seen in extensive radiological forms. As far as it goes beyond a simple ventilatory study, the measurement of the breath holding lung transfer factor for CO has proved to be a valuable element in the functional statement of anthracosilicosis. The polymorphism of the pulmonary repercussions of dust exposure explains individual differences between the results of the main investigations, and this emphasizes the need for a series of diversified tests.</p>","PeriodicalId":75638,"journal":{"name":"Bulletin de physio-pathologie respiratoire","volume":"11 4","pages":"569-88"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12389578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This lung function impairment does not affect working capacity provided the dust is not fibrogenetic. Quartz, normally present in coal mine dust in concentrations between 2 and 10% is claimed to be responsible for coal workers' pneumoconiosis (CWP) by some writers. However the evidence is conflicting and firm conclusions cannot be drawn at present. From the clinical point of view CWP is characterized by an increased airway resistance. All correlations between airway resistance, arterial oxygen and carbon dioxide pressure and intrathoracic gas volumes (IGV) in patients having CWP and obstructive airway disease are similar to those in non-dust exposed patients with obstructive ariway disease. Patients with CWP, at equivalent values of airway resistance have smaller mean values of IGV. The relationship between arterial oxygen pressure and pulmonary arterial pressure is the same in patients with CWP and obstructive airway disease as in patients with chronic obstructive airway disease but without CWP. The effect of therapy in CWP with obstructive airway disease corresponds very well to that seen in patients without CWP.</p>","PeriodicalId":75638,"journal":{"name":"Bulletin de physio-pathologie respiratoire","volume":"11 4","pages":"415-27"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12388415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Close to half the men (44.3%) had a normal lung function profile and a further 26.5% some function changes but no definite profile. Amongst the remainder restrictive and obstructive function profiles occurred with equal frequency (12.8 and 12.2% respectively). Both were associated with radiologic asbestosis; both occurred infrequently in the absence of the smoking habit. These findings suggest an association between the smoking habit and the harmful effects of asbestos exposure on lung function, and by implication on the development of lung fibrosis. A similar association has been recognized in respect of bronchogenic carcinoma. This experience, in the primary mining and milling of pure chrysotile asbestos, may not be directly applicable to secondary industries concerned with the further processing of this fibre.</p>","PeriodicalId":75638,"journal":{"name":"Bulletin de physio-pathologie respiratoire","volume":"11 4","pages":"429-45"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12388411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have measured in the arterial blood : Po2, PCO2, plasmatic pH (pHp1), pHi, P50(7,40) and 2,3-DPG. From these values. the base-excess (B.E.) and the P50 to real pH [P50 I.V.] have been computed. There is a good correlation between 2,3-DPG and P50 (r = 0.707), none between P50 and Pao2. For a normal acid-base balance, P50 and 2.3-DPG also are normal. Increased in chronic alkalosis, the amount of DPG is decreased in chronic acidosis. The DPG-pHi correlation is very good (r = 0.691 ; pless 0.001) and the changes of the acid-base balance seem to be the main factors for controlling the DPG synthesis : it increases it in chronic alkalosis and reduces it in chronic acidosis. Thus the P50(I.V.) returns to the normal range on account of the Bohr effect adjustement. On the contrary, in acute acidosis and alkalosis, the amount of DPG is normal and the P50(I.V.) is increased or reduced.
