Lung function in children with recurrent bronchitis.

Lung function was studied in 29 children suffering from recurrent bronchitis (average number of bronchitis attacks per year: 4.2 +/- 0.5). Most of them (73%) were 1--7 years old. The date of exploration in relation to the last acute bronchitis was on average 6 weeks. Lung mechanics, residual functional capacity, blood gases and regional lung function were measured. Most of the children were suffering from some kind of functional disorder; alteration of lung mechanics -- increase of lung resistance (22/29) decrease of dynamic compliance (15/23); increase of functional residual capacity (6/10), non specific bronchial hypersensitivity (12/17); regional ventilatory and perfusion malfunction. These functional disorders could be the first evidence of the bronchial lesions which cause chronic obstructive bronchitis in adults.

[Diagnosis of interstitial pneumopathies in infants (author's transl)].

The authors discuss the etiological features of interstitial pneumopathies, with particular emphasis on their characteristics in the newborn and in immunodeficient children, and review the diagnostic findings : clinical and radiological signs, functional disturbances, and results of pulmonary biopsy. The results of 154 needle biopsies in 124 children aged 1 month to 16 years are described. In 103 cases a diffuse pneumopathy was present and 80 % of the biopsies were successful. Precise diagnosis could be made from the histology specimen in 22 cases out of the 82 examined, while in 60 of these cases the specimen could be identified.

[Idiopathic pulmonary hemosiderosis in children. A report on 7 cases (author's transl)].

The authors describe 7 cases of idiopathic pulmonary hemosiderosis occurring in children, and emphasize the diagnostic value of the association of pulmonary and anemic manifestations, one of which could appear to be an isolated finding and thus delay diagnosis. Complementary investigations are discussed and the relative inocuity of a lung biopsy with a Gerbeaux needle, and the greater value of bronchoscopic samples over those obtained by gastric intubation for evaluating the presence of siderophagic activity emphasized. Functional pulmonary tests, especially for blood gases and ventilatory function, were also conducted. The difficulties in classifying the various types of pulmonary hemosiderosis, especially the "idiopathic" form in children, are outlined. Immunological disorders must be systematically searched for in order to choose the most effective therapy: corticoids or immunodepressants.

[Inappropriate secretion of ADH during acute respiratory infections due to adenovirus in children (author's transl)].

Four children aged between 7 and 19 months with severe bronchopneumonia due to adenovirus type 7, proved by virology and/or serology developed severe hyponatraemia. One of them is reported in detail: it was possible to estimate plasma ADH levels and thereby prove the existence of reversible hypersecretion of the hormone. Whilst the syndrome of hyponatraemia with inappropriate secretion of ADH has not yet been reported in association with severe pneumonia in the child, it is known in adults. The limits of the syndrome and its physiopathology are discussed. It may be due either to vagal stimulation as a result of a fall in left aressure, or to central involvement. Therapeutic implications of the problem are emphasized.
