[Changes in the isoniazid inactivation index during antituberculosis treatment in children].

Fluorimetric assays of serum isoniazid levels were performed in children treated either with isoniazid alone, or with isoniazid associated with other antituberculous drugs, in order to adjust the dosage. Study of the inactivation index at the 3rd hour, showed a faster metabolism in the younger children. Assays repeated twice or more in 160 patients, showed important variability in the results. The variation coefficient was 18,6% for the whole group and above 25% in 25% of cases. The younger age and the association of several other drugs (corticosteroids and possibly erythromycine) may be responsible, at least partly, for this variability. However, association with antituberculous drugs (ethambutol, rifampin) does not seem to change significantly isoniazid metabolism. The magnitude of these variations should lead to a greater caution in the interpretation of isolated isoniazid dosages.

[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.

[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.

[Tuberculous mediastinal adenopathy in a child].

One case of mediastinal tuberculous lymph node with fistulae into the esophagus is reported in a 9 years old girl. The first symptom was the appearance of epigastric abdominal pain, with secondary dysphagia. The diagnosis was confirmed by histology after thoracotomy and surgical excision. Esophageal tuberculosis is rare and seems to be secondary to contamination from mediastinal lymph nodes. Treatment is always medical and often requires surgery.
