[Chest pain]. / Il dolore toracico.

After a thorough description of the physiological background, the problem of chest pain is examined with extensive documentation including pictures. It is suggested that meticulous clinical assessment is of even greater value than laboratory tests or instrumental explorations for the accurate diagnosis and appropriate treatment of the condition causing the pain. In other words laboratory and instrumental assessments should be based on and used to confirm an approximate diagnosis formed on clinical data.

[A documented case of typical Hamman-Rich interstitial pulmonary fibrosis]. / Su di un caso accertato di tipica fibrosi polmonare interstiziale di Hamman-Rich.

Following a brief mention of the classification of Hammer-Rich disease within idiopathic diffuse pulmonary fibrosis, the main clinical, radiological and laboratory features of these disease are outlined in brief. A personal case, subsequently controlled neroptically and histologically, is then described. From comparison between reported data and findings in the personal case, it is concluded that it was a typical, rare case (less than 150 others have so far been reported in all world literature) of Hamman-Rich disease. Other diagnostic hypotheses can be rejected because they are less correspondent to the typical picture and for various other considerations.

[Phenomenon of primary resistance of Koch's bacillus: report on cases assembled at the pneumological hospital S. Luigi in Turin from 1972 to 1975]. / Il fenomeno della resistenza primaria del bacillo di Koch: casistica raccolta nell'ospedale pneumologico S. Luigi di Torino dal 1972 al 1975

In this work the authors stress the importance reached in recent years by the primary resistance phenomenon in pulmonary consumption, and they explain the results pointed out by the examination of 171 antibiograms effected from 1972 to 1975 on patients with pathological forms ascertained for the first time. They conclude by underlining the reduction of the primary resistance when employing common antibiotics and, on the contrary, its rise with the use of the rifampicin which has recently been introduced in therapy; lastly they put into evidence the epidemiological importance of the phenomenon itself.
