[Tuberculosis or hepatic granulomatosis? (author's transl)].

The authors report 43 observations of pulmonary or extra-pulmonary tuberculosis, bacteriologically proved, in which liver biopsies revealed more or less complete granulomatous lesions. The culture of 29 liver fragments on Löwenstein and Colestos medium enabled the identification of the tuberculous bacillum in only one case. In the other cases the hepatic lesion has only been related to the tuberculosis because of the clinical and bacteriological context. Therefore, besides exceptional cases where Koch bacillum is revealed in the liver parenchyma, it seems that granulomatosis can be considered a control for the delayed hypersensitivity reaction to the tuberculous antigens, and not to the tuberculous infection localized to liver.

[Lung function and gastroesophageal reflux during chronic bronchitis (author's transl)].

The coexistence of gastroesophageal reflux (GER) and respiratory diseases has led us to raise three questions : 1) how frequent is GER in patients with chronic bronchitis?, 2) is the respiratory function in patients with chronic bronchitis different when they have a GER and when they do not?, 3) is the GER different in patients with chronic bronchitis and in subjects not suffering with chronic bronchitis? The study of esophageal pH after a test meal showed there was a GER in 29 out of the 47 patients studied. The measurements of lung volume, air flow, pulmonary compliance, as well as the alveolo-capillary transfer of carbon monoxide, showed that there was no difference in the lung function of bronchitics whether they had a reflux or not. On the other hand, refluxes are less frequent but longer in patients having bronchitis and a GER, than in those having a GER but not having bronchitis. This must be linked to a low esophageal clearance which could be related to the attack of bronchitis. Only a well carried out prospective study of the treatment of GER in patients will reveal if the reflux increases bronchitic symptoms.

Evaluation of large-needle biopsy for the diagnosis of cancer.

The arguments for a choice between a large or fine needle in the diagnosis of tumors are still unclear. This paper reviews the advantages and disadvantages of large-needle biopsy and fine needle aspiration. Reports indicate that although the procedures have the same diagnostic efficacy, the risk of tumor seeding is far higher following large-needle biopsy. For this reason it should be avoided for the diagnosis of cancer. The risk of tumor seeding after fine needle aspiration may be reduced by performance through a cover of normal parenchyma, by maintaining suction during withdrawal of the needle and by examining samples for quality during the procedure.
