Systematic Chest Radiography during Pre-Employment Check-Up

ABSTRACT

The aim of this study was to specify the importance of chest radiography during pre-employment check-ups in the tropical environment. A cross-sectional study of chest X-rays of 2540 apparently healthy job applicants in seven private companies in Abidjan; Cote d'Ivoire; was carried out over a 5-year period. The chest X-rays were performed in posterior-anterior; frontal; standing position. Two senior radiologists performed a double-blind study in search of parietal; mediastinal; and pleuroparenchy-matous abnormalities. The 2540 subjects were all males with ages ranging between 20 and 36 years. In 93of the cases (2372 job applicants) the frontal chest X-ray was normal but 168 (7) presented abnormal images. The observed lesions were dominated by cardiomegaly (102 cases) followed by pulmonary parenchymatous lesions (35 cases); and by pleural liquid effusions (10 cases). The parenchymatous abnormalities were represented by 35 evolutional lesions in the form of 12 apical parenchymatous infiltrates; 7 excavated apical pneumopathies; and 16 non-excavated condensations. The 10 cases of pleural abnormality were encysted pleuritis. Frontal chest radiology can be useful in pre-employment check-ups in the tropical environment by helping to screen for contagious pulmonary lesions that may be undetected at a clinical examination
