[Necrotizing fasciitis of the breast and HIV infection. A case report]. / Fasciite nécrosante du sein: une observation chez une personne vivant avec le VIH en Côte d'Ivoire.

Necrotizing fasciitis is a severe soft tissue infection caused by flesh-eating bacteria. It usually occurs on the lower limbs. The purpose of this report is to describe a case involving Streptococcus pyogenes on the breast of a 22-year-old African woman with HIV.

[Impact of Buruli ulcer secondary prevention program in an endemic area in Côte d'Ivoire]. / Effets d'un programme de prévention secondaire de l'ulcère de Buruli dans une zone d'endémie d'ulcère de Buruli en Côte d'Ivoire.

Mycobacterium ulcerans infection or Buruli ulcer begins by a papule, nodule, blotch or oedema and develops into ulceration with complications which can lead to disabilities. Its prevalence is high in West Africa and in Côte d'Ivoire particularly. Until recently, only ulcerated forms were mostly observed, whereas nodular ones were unnoticed or did not draw patients' attention. From 1999 to 2002 we conducted a before-after survey in the endemic area of Zoukougbeu located in Daloa region, the central west part of Côte d'Ivoire in order to assess the potential impact of a screening and treatment strategy for nodular forms of Buruli ulcer on ulceration rate decrease. The survey used clinical criteria necessary to identify Buruli ulcer nodule which were defined according to a former study carried out in the same area in 1998. As result of our survey 781 Buruli ulcer cases were reported of which 34.7% were ulcerative forms, 61.1% were nodules and 4.2% were other forms (blotch and oedema). By comparing the data of 1999, when the prevention program started, to those of 2002, we observed a drop of 47.6% in the ulcerative lesions and an increase of 57.4% in nodule ones. These changes were statistically significant (p < 10-5). Annual trend, from 1999 to 2002, showed a decrease in the detection rate of the respective forms under study. It ranged from 25.8/10000 to 7.3/10000 for ulcerative lesions and from 23/10000 to 19.7/10000 for nodules. In spite of possible defects in the methodology of a before/after survey the incidence decrease of both ulcerative and nodular forms that coincided with the prevention program probably reflects the efficacy of the secondary prevention program that promotes early diagnosis and treatment of nodular forms of Mycobacterium ulcerans infection.

Caused by Mycobacterium ulcerans, Buruli ulcer is an infectious disease which leads to large cutaneous ulceration and is responsible for huge socio-economic consequences. Since 1997 the World Health Organization has started a global Buruli ulcer initiative in which African endemic countries are committed. After an epidemiological background of the disease in Côte-d'Ivoire and a description of the different clinical aspects, we report the main disease management actions carried out in the country by the National Program for Buruli ulcer control from 1998 to 2003. It seems that surgical team missions carried out in health center to treat cases, early detection and treatment of cases together with the implementation of a specific poly-chemotherapy lead to an effective control of the disease.

Ulcer caused by Mycobacterium ulcerans and called Buruli ulcer is characterised by large cutaneous ulceration which often leads to debilitating sequelae. The disease occurs in swampy and stagnant water areas in intertropical regions of Asia, the Indian Ocean, Latin America and Africa. West Africa has been affected for two decades with a significant increase in the last ten years. In Côte d'Ivoire, from 1991 to 1994, 2,246 cases have been detected. In 1995, the cumulative number was 5000 cases distributed throughout the forested and marshy areas of the southern part of the country. In order to assess the magnitude and severity of the disease in Côte d'Ivoire and to collect data necessary for developing a control plan, the National Programme of Buruli Ulcer Control (PNUM) conducted an extensive cross-sectional nation-wide survey. The results provide a total cumulative number of 10,382 cases distributed throughout almost all regions. The number of active cases was 4,642 which was equivalent to a prevalence of 0.32 per 1000. Buruli ulcer is the second most prevalent mycobacteriose in Côte d'Ivoire after tuberculosis and before leprosy. From 1996, the average annual incidence exceeded 2,000 cases. Moreover, the main identified risk factor was the presence of a watering point used by people nearby. Children were affected at a rate of 57%, with male predominance, while in adult cases, the female rate was higher. Children and women enjoyed higher recovery rates. Ulcerated cases represented 89.5% of active ones against 6.5% for oedematous forms and 4% in nodule cases. Definitive sequelae were more frequently observed in children with no difference of sex. We conclude that Buruli ulcer has been endemic in Côte d'Ivoire and is characterised by the severity of the lesions.
