[Analysis of interval cancers in the Program of Early Diagnosis of Cancer of the Breast of the Community of Valencia. Group of Readers of the Prevention Units of Cancer of the Breast].

A retrospective search was performed of interval cancers in the Programa de Prevención de Cáncer de Mama de la Comunidad Valenciana. The cancer rate observed was 0.5 per 1,000 women studied. The mean diagnostic time from the first mammography was 11 months, and the most frequent detection means was a positive palpation. The frequency was higher in women aged less than 55 years. More "non-common" histologic types were found and a lower percentage of conservative therapies regarding cancers detected at the first round of the Program, although the stage was similar to the latter.

CT findings in Swyer-James syndrome.

Swyer-James syndrome (SJS) is usually diagnosed with plain chest radiographs obtained during inspiration/expiration. The authors studied patients with CT to assess its value in the evaluation of this syndrome. In patients with SJS, CT was useful in the determination of bronchial patency (all nine patients), lung parenchymal changes (subpleural infiltrates in six patients, atelectasis in two, and cavities in two), and the extent and degree of bronchiectasis (all nine patients). If CT is used for the evaluation of bronchiectasis, knowledge of the main findings associated with SJS (hyperlucent lung without anteroposterior gradient attenuation [n = 8], small lung [n = 6], and diminished central and peripheral pulmonary arteries [n = 9]) should facilitate the diagnosis of associated SJS. Expiration CT would support the diagnosis with demonstration of air trapping.

[Extraperitoneal appendicular calculi (author's transl)].

Two retrocecal and extraperitoneal appendix cases are showed. Atypical clinical signs, slow evolution, perforation and abscess were found. Radiological diagnosis is based by seeing the calculus and the appendix by means of barium enema. When appendix calculus is demonstrated and clinical signs are present, a surgical operation must be order urgently. Profilactic appendicectomy is recommended when no symptoms.
