[Detection and treatment of early forms of Mycobacterium ulcerans infection in Ivory Coast].
Mycobacterium ulcerans infection (Mu) is an emerging public health problem. The cumulative number of cases in Ivory Coast was 10,382 in 1997. One of the key points of the Yamoussoukro "global initiative" in December 1997 involved detection and treatment of cases at the early-disease stage. The threefold purpose of this transversal study was to determine the frequency of nodular-stage Mu infection, to describe the features of the nodules, and to identify nodular features suitable for early screening use. Of the 93 nodules removed, 58.1% were due to Mu, indicating that the prevalence of nodular-stage Mu in Zoukougbeu, Ivory Coast was 9 per 1000 inhabitants. All Mu nodules were recent, caused pruritus, and displayed oedematous edges. The mean duration of disease was 23 months. In endemic areas, Mu infection should be suspected for any lesion that is of recent onset (< 5 year), shows visible elevation, has a diameter of 3 cm or more, or is mobile under the skin. Cold nodules that are adherent to the superficial skin layer and located on the limbs or firm cold nodules should also be considered as suspect. Excision of cold nodules caused by Mu is recommended. The wound heals within 4 weeks and no recurrences have been reported after 6-month follow-up.
