[Bronchial fibroscopy. Indications and results].

The authors report a personal experience of 1.159 bronchial fibroscopies performed in 3 years. They review the literature for the indications and results of bronchial fibroscopy (except results on trans-bronchial biopsies). The diagnostic value of this technique is highly superior, where bronchopulmonary cancers are concerned, to the traditional bronchoscopy. Besides these classical indications, the place of bronchial fibroscopy in intensive care, and its help for bacteriological and parasitological diagnoses, must be underlined.

[Respiratory and hemodynamic functional tests in funnel chest].

Fifty three patients with Pectus excavatum, 12.5 years of age on average, were studied. They frequently had respiratory history (in 36% of cases): asthma, repetitive bronchites or rhinopharyngites, and associated squeletal deformities (17%) : kyphoscoliosis, lordo-kyphosis and scoliosis. As far as ventilation is concerned, the restrictive syndrome was found in 49% of cases, severely in 23% (20% decrease in C. V.) An obstructive syndrome was found only in cases of associated asthma. Bodypletysmography done parallely in 5 cases puts in evidence or increases the ventilatory abnormalities. In the cardio-vascular check up, the chest X ray, E.C.G., the pulmonary scintigraphy or straight microcatheterization, usually reveal some abnormality (15% of cases). The synthesis of results points out two facts : 1) when the heart is in its position and the cardiomediastinal shadow enlarges, the E.C.G. abnormalities are unimportant; when the heart is displaced towards the left, the electrical disorders are bigger ; 2) microcatheterization done on 22 subjects revealed a gradient of systolic pressure, right ventricle-pulmonary artery, definite or severe in 4 cases, lesser in 9. Surgery rarely improves the spirometry and E.C.G. abnormalities, but does seem to cure the hemodynamic disorders.

[Surgical treatment of funnel chest].

The main problems of indication, operating techniques and results are recalled after 39 cases of pectus excavatum (P.E.) operated on 74 followed up children. Analysis revealed frequent family trend, respiratory past records of Marfan's morphological type and intrathoracic spur. Sternochondroplasty had varied stabilizing ways : first Garnier's technique, then Judet's costal clips, today the mediastinal rod of Morel. The relative deterioration of morphological results depended on the reliability of the manner of fixing. For good results, neither age, sex, nor the importance of the retraction interfered. The unfavourable elements are the gently sloping thorax and associated vertebral manifestation.

[Note on the complications of pleural needle biopsy: neoplastic seeding of the wall (apropos of 300 effusions and 440 puncture biopsies)].

Out of 440 pleural biopsies done with Abrams or Castelain needle, performed over 11 years in 300 pleural effusions, only 14 incidents of accidents occurred. There were 9 minor ones (intrapleural bleeding, subcutaneous emphysema, pneumoserosa by aspiration). Neoplastic graft along the biopsy tract was observed in 5 cases, of which 4 were primitive malignant mesotheliomas and one a primitive appearing neoplastic pleurisy. The risk of parietal neoplastic seeding runs high in malignant mesothelioma, considering that 11 such cases were included in this series of biopsied patients. This risk is not specific to plaural biopsy and can be encountered in simple thoracentesis. This complication therefore is not a contra-indication to needle biopsy as it is only observed in diseases beyond surgical redemption.

[Normal value and age and sex correlations of mean expiratory output (25-75%). Diagnostic value in early obstructive bronchopneumopathies].

The maximum output of half-expiration (MMFR) or DME 25-75% is studied in 136 subjects, evalued as non obstructive, after the determination of the MEVS/VC X 100. The values noted are reported to the body surface (S) in order to eliminate the biometric differences. A highly close correlation, of the exponential type, is thus put in evidence for each sex between the DME/S and the age of the subjects. The study of the DME in subjects with obstructive Tiffeneau makes possible: a) to determine an inferior limit of the normal condition; b) to bring confirmation of the fiability of the test. The study of the determination of the DME/S is then performed in subjects with normal MEVS/VC X 100 and clinically suspect of bronchial obstruction (tobacco addicts, patients at stage I of chronic bronchitis, asthmatic patients outside the attacks). The DME determination lets appear the presence of a bronchial obstruction in almost one half of the subjects submitted to study.
