[Radiologic analysis of known-interval cancers after 2 years of organized mass screening for breast cancer in Ille-et-Vilaine]. / Analyse radiologique des cancers d'intervalle connus apres deux ans de campagne de dépistage de masse organisé (DMO) du cancer du sein en Ille-et-Vilaine.

The first thirty-two known interval breast cancers (appearing within the first or second year after a negative screen) occurring during a two-year breast screening round were reviewed and the radiograms analyzed. Five classes were established: true interval cancers (13/32 cases), radiologically occult cancers (2/32), cancers with no specific sign (7/32), false negative cancers (5/32) and unclassifiable cancers (5/32). In more than 50% of the cases, there was no abnormality on the initial radiographic test, although the literature reports that the rate of false-negatives in interval cancers is less than 20%. Standard classification (by at least 3 readers) is very important to provide a possible explanation of cancer development. Action should be initiated to reduce their number.

[Two monozygotic twin sisters affected with a severe form of osteogenesis imperfecta congenita (author's transl)]. / Deux jumelles monozygotes atteintes d'une forme grave d'osteogenesis imperfecta congenita (maladie de Porak et Durante).

Description of two monozygotic twin sisters both showing at 6 1/2 months of intrauterine life the existence of a severe form of osteogenesis imperfecta. On this occasion the authors insist on the necessity of X-rays in cases of stillbirths which will enable the physician to give an appropriate genetic advice.

[X-ray pictures in pneumonia caused by Pneumocystis carinii. Nine cases of immunodepressed patients (author's transl)]. / Aspects radiologiques de la pneumonie à Pneumocystis carinii. A propos de 9 observations de patients immunodéprimés.

The authors analyse the pulmonary symptoms found by X-Ray in nine immunodepressed patients who were hosts to Pneumocystis carinii. The radiological abnormalities do not generally appear early nor are they specific; the syndrome of diffuse alveolar consolidation only appears at a late stage, it is most serious in the base and the peri-hilar regions, but does not affect the apex. It would appear that no prognostic value can be ascribed to the radiological results. The authors therefore suggest bronchial scanning for tracking down the Pneumocystis whenever suspicious clinical symptoms appear.

[Application of the distal bronchial brushing technic to the bacteriological diagnosis of pulmonary tuberculosis]. / Application de la technique du brossage bronchique distal au diagnostic bactériologique de la tuberculose pulmonaire

The tubercle bacillus was sought in samples obtained by bronchial brushing in 36 patients whose tuberculosis was demonstrated and in whom a direct examination of the sputum had given only negative results. In 5 cases, the tubercle bacillus was demonstrated only in the sample obtained by brushing, by direct examination and positive cultures in one case and in the other cases, culturutum coughed up after brushing.
