RESUMEN

The benefit of chemotherapy for patients with disseminated non small cell lung cancer (NSCLC) is controversial. The introduction of cisplatinum in the combination chemotherapy for NSCLC gave rise to higher response rates. To study the question of the usefulness of cisplatinum-based chemotherapy in disseminated NSCLC we conducted a prospective randomized trial comparing best supportive care to vindesine + cisplatin. Between December 1985 and March 1988, 49 patients with stage IV NSCLC were enrolled. Of the 46 eligible patients 24 were in the chemotherapy group and 22 in the best supportive care group. The treatment groups were not significantly different in terms of age, performance status, histology. Toxicity on the chemotherapy arm grade 3 or more was observed in 17.5% for neutropenia, in 8.75% for vomiting. There was one death related to treatment. The overall response rate in the chemotherapy group was 41.7%. Patients of the chemotherapy group had a median survival time of 199 days and the patients of the best supportive care group had a median survival time of 73 days. The difference in survival is highly significant (p less than 0.001).

RESUMEN

The spontaneous evolution of 60 patients suffering from recently diagnosed sarcoidosis was compared with their initial biological profile of "activity". 47% of this unselected group of patients belonged to an inactive group (ACE less than 35 nmol/ml/mn and the percentage of alveolar lymphocytes less than 30%). After a mean period of two years of follow up it turned out that the initial bioprofile of activity had no predicted value, even in the absence of any initial elevation of the markers (3 cases out of 28 grew worse). The repeated controls of criteria of activity did not objectively show any concordant change with the outcome in such cases. It is necessary to point out the unfavourable character of very raised ACE activity greater than 50 nmol/ml/mn (7 deteriorations out of 8 cases). It would appear that a systematic search for these criteria should be deferred principally in type 1 lymph node involvement or pulmonary and mediastinal type IIA, all the more so as in practice they have little influence on therapeutic decisions.

RESUMEN

The syndrome of ovarian hyperstimulation is a little known aetiology of pleural effusion. It should be thought of in young women who are under treatment to induce ovulation. Serous effusions which occur in these cases are a serious sign. The effusions are exudates and not transudates as occurs in Demons-Meigs syndrome. The treatment which will be undertaken ought to consider the possibility that a pregnancy is underway.

RESUMEN

We report a case of a 62 year old man who presented with effort dyspnoea accompanied by a cough and haemoptysis. The chest radiograph of the thorax showed atelectasis of the right upper lobe. Bronchoscopy showed evidence of a tumour like mass obstructing the right bronchus and this revealed itself to be a mass of organised fibrinous deposit in granulation tissue containing numerous colonies of Aspergillus. In fact it appeared to be an obstructive Aspergillus bronchitis, with a pseudo-tumour appearance attached to a carcinoid tumour which was obstructing the apical segment of the right upper lobe. Obstructive Aspergillus bronchitis makes up only a small percentage of overall respiratory disease caused by Aspergillus. They pose a problem of differential diagnosis with bronchopulmonary aspergillosis which is much more frequent.

RESUMEN

Owing to a technical analysis enabling the detection of mineral elements present in trace amounts in small volumes, an analysis of the liquid obtained in 148 broncho-alveolar lavages could be studied. The elements consistently recovered were as follows: iron, copper, zinc, nickel, lead and titanium. Normal values were established. In the absence of exposure, there was no significant difference distinguishing the different pulmonary diseases studied. In occupational disease, the presence of iron in large quantities, tungsten, nickel and rare earths could be shown objectively, as well as the persistence of gold or iodine after medical absorption. However, this preliminary work does not allow one to establish a formal correlation between the alveolar concentrations obtained and the pulmonary disease observed.

RESUMEN

We applied the energy-dispersive x-ray fluorescence technique to determination of trace elements in human bronchoalveolar lavage fluids. Our analysis of more than 200 samples allowed us to determine normal reference values, to be used in characterizing occupational exposure. These values are expressed both in nanograms per 1000 cells (of all kinds) and nanograms per 1000 macrophages to correlate lavage efficiency and dust content of the alveoli. The result expressed in milligrams per liter is not sufficient, because some healthy volunteers showed high concentrations of iron but normal values when expressed vs the number of cells. Some examples of abnormal compositions of broncho-alveolar lavages are reported and the fully automated spectrometer developed for clinical and biological investigations is described.

RESUMEN

Five cases of uninodular bronchioloalveolar cell (BAC) carcinoma are reported. These 5 cases were characterized by the protracted course of the disease: 14.5 and 11.5 years respectively in the 2 patients who died; 7.5, 12 and 12.5 years respectively in the 3 patients who are still alive. Prior to being diagnosed at excision, the tumours had been followed up for an unusual 2 to 10 years period, with phases of radiological stability and phases of very slow growth. This very slow course is exceptional in lung cancer. It differs not only from the course of diffuse BAC carcinoma, but also from the habitual course of uninodular BAC carcinoma and from that of peripheral adenocarcinoma. Similar cases could be found in the literature, and a comparative study has been conducted between these slow-course carcinomas and normal-course carcinomas. Whatever their outcome, slow-course carcinomas are asymptomatic tumours which present at radiography of the chest as a peripheral round or oval opacity devoid of pathognomonic features. The post-operative prognosis of slow-course tumours seems to be more favourable than that of the other lung cancers. At histology, carcinomas with a protracted course usually show a pattern similar to that of lesions called by some authors "benign adenomatosis"; however, some of these tumours exhibit fairly distinct signs of malignancy, and electron microscopic images also are far from being uniform.

RESUMEN

We applied energy-dispersive x-ray fluorescence to the determination of abnormally present elements or abnormal concentrations of elements in human broncho-alveolar lavage fluids. The low detection limits and the ability to perform multi-elemental analysis permit one to establish or confirm occupational exposure of workers. We also describe different methods used to check our method and our results. We report examples of abnormal compositions of broncho-alveolar lavages containing W, Ce, La, Nd, I, Fe, or Ni. We discuss the limits of the method for characterizing silicosis or asbestosis.

RESUMEN

In an attempt to find better criteria for the evaluation of prophylactic treatment of asthma, we have studied the significance and the correlations of the 3 parameters usually measured: symptoms, bronchodilator requirements, changes in Peak Expiratory Flow (PEF). We have collected these data daily over a 16 week period in 13 adult asthmatics allergic to Dermatophagoides pteronyssinus. For each patient, the 3 scores were compared graphically. Linear regression was used to analyze the individual relationship between 2 daily scores. Incomplete cards mostly revealed unexpected behaviour (e.g. normal lung function but many symptoms recorded) and cannot of course be taken into account in a trial protocol. We found a good correlation between PEF and symptom scores in 10 out of 13 patients and we could point out the poor correlation between medication score and the other scores. To our knowledge, it is the first time such an objective result has been shown in asthmatic adults. Our analysis provides data which should improve the studies of prophylactic treatment efficacy in asthma.

RESUMEN

The invasive aspergillus pneumonias have been described particularly in chemotherapy for patients with haematological disorders. In respiratory disorders such cases are exceptional. The authors report a case of invasive aspergillus pneumonia, occurring during treatment of a small cell cancer; the rapid commencement of anti-fungal treatment by Amphotericin "B" and Flucytosine enabled an apparent cure of the tumour by radiotherapy and chemotherapy. The authors stress the difficulty of definitive diagnostic criteria at the beginning of the disorder and also the need to start anti-fungal treatment as soon as possible.

RESUMEN

A precise assessment of pulmonary arterial hypertension (HTAP) in chronic lung disorders is not possible without right heart catheterisation. In spite of technological advances (floating catheters with or without balloons) the examination remains invasive, at least to a certain degree, in addition it is not currently practiced in respiratory function laboratories or in services specialising in thoracic medicine. The diagnosis of HTAP is important when considering both the prognosis and the therapeutic approach notably in chronic airflow obstruction (BPCO) and thus the interest in non-invasive diagnostic methods for HTAP. Do current methods offer such a diagnosis? It is this question that the authors endeavour to answer in analysing the possibilities of the principle methods available, from the most standard (eg ECG, chest radiographs) to the most recent (right heart echo-cardiography, myocardial scintigraphy, isotopic measurement of the right heart function). The reference factor is usually the mean pulmonary artery pressure at rest (PAP) supplied by right heart catheterisation. The ideas of sensibility and specificity of a method are defined and the importance of the correlation between the numerical results obtained by a given method and right heart catheterisation is emphasized: only a very strong correlation could assure the possibility of a correct prediction of the level of PAP. Individually no current methods allow such a prediction in a satisfactory manner. Right heart echo-cardiography is "a priori" the most tempting, but it is unfortunately difficult to accomplish in patients with BPCO. Bidimensional echo-cardiography and the Doppler have given very promising results, which need to be confirmed in patients with BPCO. By combining the results of several methods (eg. ECG, radiological measurements, echocardiography) to those of respiratory function (FEV1, PaO2, PaCO2) one can predict in a satisfactory manner the existence (or the absence) of HTAP but not the precise level of the PAP. An approach of this kind may help to limit the indications for right heart catheterisation which remains irreplaceable for the precise knowledge of pulmonary hemodynamic parameters.

RESUMEN

Ninety-three patients with severe chronic obstructive pulmonary disease (COPD) of the bronchitic (n = 74) or emphysematous type (n = 19), who all had arterial hypoxemia, underwent 2 right cardiac catheterizations in a clinical steady state, with a delay of 5 yr or more between the first and the last catheterization. No patients received long-term O2 therapy or pulmonary vasodilator drugs. Patients were divided into 2 groups according to the initial level of mean pulmonary artery pressure (Pap). Group 1 included 61 patients without initial pulmonary arterial hypertension (PAH), Pap being less than 20 mmHg; the average delay between the 2 catheterizations was 93.4 +/- 26.8 months. Group 2 included 32 patients with initial PAH (Pap greater than or equal to 20 mmHg), and the average delay was 85.0 +/- 26.0 months. The changes in Pap were small. They ranged from 15.5 +/- 2.4 to 19.6 +/- 7.0 mmHg in Group 1 (p less than 0.001) and from 25.8 +/- 5.6 to 27.8 +/- 9.5 mmHg in Group 2 (NS). The average increase in Pap was 0.65 mmHg/yr in Group 1 and 0.39 mmHg/yr in Group 2 (no statistical difference between the 2 groups). The other hemodynamic parameters (pulmonary capillary wedge pressure, right ventricle filling pressure, cardiac output) did not change. Hemodynamic "worsening," which was defined by an increase in Pap by greater than or equal to 5 mm Hg, was observed in 29% of the patients (n = 27). In these patients, there was a marked worsening of hypoxemia, which was not observed in the remaining 66 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

A total of 258 patients with suspected sarcoidosis underwent transbronchial needle aspiration lymph node biopsies and forceps bronchial biopsies during rigid bronchoscopy. Transbronchial needle aspiration biopsies revealed noncaseating granulomas in 66.3 percent of patients. When transbronchial needle aspiration biopsies were combined with forceps bronchial biopsies, the positive rate increased to 77.7 percent. No major complication occurred when using transbronchial needle aspiration. Rigid bronchoscopy with transbronchial needle aspiration biopsies appears to offer a sensitive and specific alternative to more invasive techniques used in the diagnosis of sarcoidosis.

RESUMEN

Although on the increase overall, the actual prevalence of occupational asthma is difficult to assess because of variations seen according to periods, countries, jobs, and the agents responsible. In the authors' experience, this prevalence is slightly less than 10%. Three principal mechanisms, sometimes present together, not always elucidated: immunological, reflex and irritative, are responsible for such asthma. Whilst a positive diagnosis raises few problems, the aetiological diagnosis is difficult and involves two stages: recognition of the occupational characteristic of the asthma and attribution of this asthma to an allergen or substance in the occupational environment. Skin tests and in vitro tests, but above all exposure tests, make an important diagnostic contribution. Personal examples are used to illustrate the principal aetiological factors in occupational asthma of animal, vegetable or chemical origin.

RESUMEN

Recurrence of thoracic sarcoidosis after spontaneous regression is extremely rare. Its existence is proven by two new cases associating sarcoidosis with L ofgren 's syndrome and sarcoid in skin scars, the latter facilitating the recognition of the presence of thoracic disease. Surveillance of the behaviour of scars forms part of routine examinations in the sarcoid patient. Even when there has been total spontaneous regression, subsequent clinical and radiological follow-up every two years must be continued.
