[Comparison of annual risk for tuberculosis infection (1994-2001) in school children in Djibouti: methodological limitations and epidemiological value in a hyperendemic context].

The purpose of this report was to describe a tuberculin survey conducted in 2001 to assess the trend in the annual risk for tuberculosis infection in Djibouti and compare resulting data with those obtained in a previous survey conducted in 1994. In 2001 cluster sampling allowed selection of 5599 school children between the ages of 6 and 10 years including 31.2% (1747/5599) without BCG vaccination scar.

[Intrathoracic Pott's abscesses, radiologic pitfalls for the pneumologist].

The authors have conducted a retrospective study of 200 cases of tuberculous spondylitis, and wish to draw attention to the clinical and, chiefly, radiological aspects of the disease. Intrathoracic Pott's abscesses are principally observed in developing countries but they are not exceptional in France, and their varied semeiology deserves to be described.

[Peripheral lymph node tuberculosis in Djibouti].

153 well documented records, gathered in one year in a Tuberculosis Center, were studied. Adenoid localization represents on fourth of all tuberculosis, and 95% of all etiologies of peripheral adenopathies. Value of bacteriological tests is studied and compared to the one of histology.

[Mycobacteria encountered in Djibouti].

The authors studied 198 strains of mycobacteriae from different sources, but mainly from bronchial secretion and adenoid pus or poundings. Because the preponderance of peripheral adenoid tuberculosis, we might fear a focus of Mycobacterium bovis. But this study gives leave to state positively that Mycobacterium tuberculosis hominis is almost exclusively the responsible and consequent by that there is an human reservoir almost exclusive.
