RESUMO
INTRODUCTION: Mantle cell lymphoma is a rare lymphoma of the gastrointestinal tract that may present as multiple lymphomatous polyposis. We report a case of lymphomatous polyposis with a review of the literature. CASE REPORT: A 56-year-old man of Black ethnicity and Ivorian nationality with no relevant past medical history, consulted for a sudden onset symptoms of gastrointestinal obstruction, which evolved over 2 days. Macroscopic examination revealed the presence of multiple polyploid formations of the colonic mucosa. Histology showed diffuse lymphomatous proliferation of submucosa consisting off small lymphoid cells with a hyperchromatic crenelated nucleus, suggesting lymphomatous polyposis. Immunohistochemical examination showed expression by the tumor cells of antibodies to CD20, CD5, Bcl2, and cyclin D1. They did not express antibodies to CD10 and CD23. The Ki67 proliferation index was 25%. We have thus retained the diagnosis of mantle cell lymphomatous polyposis. CONCLUSION: Multiple lymphomatous polyposis is a rare entity characterized by the presence of numerous gastrointestinal polyploid lesions sometimes involving several segments of the gastrointestinal tract. Typical lymphoma presenting as lymphomatous polyposis is mantle cell lymphoma; although, other tumors may have this aspect.

Breast cancer is the second cancer of women in Mali. Immunohistochemistry is poorly performed in our African countries. OBJECTIVES: To describe the immunohistochemical aspect and determine the prognosis of breast cancer. METHODOLOGY: This is a retrospective descriptive study (March 2006-July 2016) in the General Surgery Department of Gabriel Toure University Hospital in Bamako, Mali. Immunohistochemistry was performed in all patients through a collaboration of our German partners. RESULTS: We collected 98 patients (95 women and 3 men) with an average age of 40.04 ± 13.07 years. Twenty-two patients (22.44%) had a personal history of benign breast disease. In 16 patients (16.33%), we found a family breast cancer. The most common histological types were intra ductal carcinoma with 84 (85.72%) and invasive lobular carcinoma in 9 cases (9.18%). Immunohistochemistry found a predominance of triple negative with forty nine patients (50%) followed by Luminal A subtype with 26 cases (26.23%). According to the TNM classification, 44 patients (44.90%) were received at stage III. The median survival was 60 months in the group of patients who received hormone therapy versus 28 months for the group without hormone therapy (p = 0.007). CONCLUSION: Immunohistochemistry is essential for the adequate management of breast cancer. Its realization has allowed us to improve the prognosis of hormone-dependent cancers.
Le sein est le deuxième siège du cancer chez la femme au Mali. Les examens immunohistochimiques sont peu réalisés dans nos pays africains. OBJECTIFS: Décrire l'aspect immunohistochimique et déterminer le pronostic du cancer du sein. MÉTHODOLOGIE: C'est une étude descriptive à collecte rétrospective (mars 2006-juillet 2016) dans le service de chirurgie générale du CHU Gabriel TOURE de Bamako au Mali. L'examen immunoihistochimique a été réalisé chez tous les malades grâce à la collaboration de nos partenaires allemands. RÉSULTATS: Nous avons colligé 98 malades (95 femmes et 3 hommes) avec un âge moyen de 40,04 ± 13,07 ans. Vingt-deux malades (22,44 %) avaient un antécédent personnel de pathologie bénigne du sein. Chez 16 malades (16,33 %), il y avait une notion familiale de cancer du sein. La prise d'Åtroprogestatifs a été évoquée chez 28 femmes (28,57%). Les types histologiques les plus fréquents étaient le carcinome canalaire infiltrant avec 84 (85,72%) et le carcinome lobulaire infiltrant dans 9 cas (9,18%). L'immunohistochimie a permis de trouver une prédominance du triple négatif avec quarante neuf malades (50%) suivi du sous type Luminal A avec 26 cas (26,23%).Selon la classification TNM, 44 patients (44,90 %) ont été reçus au stade III. La médiane de survie a été de 60 mois dans le groupe des patients ayant bénéficié d'une hormonothérapie versus 28 mois pour le groupe sans hormonothérapie (p=0.007). CONCLUSION: l'immunohistochimie est essentielle pour la prise en charge adéquate des cancers du sein. Sa réalisation nous a permis d'améliorer le pronostic des cancers hormono dépendant.

In April 2008, seven years after the outbreak of 2001, Abidjan faced another epidemic of yellow fever. Three weeks after the case detected in the commune of Treichville at 28(th) of April 2008, two other cases were notified, the first one in Port-Bouet and the second one in Cocody located respectively in the south and north of the city of Abidjan. In order to determine a large-scale risk of urban yellow fever epidemic, epidemiological and entomological investigations were conducted by the Ministry of Health and Public Hygiene of Cote d'Ivoire with the support of the Global Outbreak Alert and Response Network. Entomological investigations revealed the predominance of Aedes ægypti, urban vector of yellow fever in neighborhood visited with larval density indices between 2 and 5, indicating the existence of a sufficient density of the vector for cause an explosion of the epidemic. In fact, the massive influx of people from inside cities towards Abidjan caused by the socio-political crisis occurred in the country in 2002, the deterioration of environment with the creation of more breeding sites of Ae. ægypti as corollary and the circulation of the virus at mosquito level were many factors favorable to the yellow fever outbreak in Abidjan city.

In November 2009, ten suspicious cases of yellow fever, including six deaths, were notified in the region of Denguélé, in the northwest of Côte-d'Ivoire. In order to evaluate the extent of yellow fever virus circulation and the risk for local people, a mission of entomological investigation was carried out by the Ministry of Health and Public Hygiene of Côte-d'Ivoire. Entomological investigations were conducted in the villages of confirmed cases (Banakoro and Tron-Touba) and the centers of consultation and hospitalization of cases during illness. Breteau index and recipient index were quasi nil. Aedes aegypti was absent among the captured mosquitoes. On the other hand, Aedes luteocephalus and Aedes opok were present at Banakoro and Tron-Touba with respective average biting rates of 0.8 and 0.6 bite/man/twilight. This situation of epidemic in the northwest of Côte-d'Ivoire could be explained by the deterioration of Denguélé region's health system which is a consequence of the war started in the country in 2002 and which has lowered the immunity of the population.

An epidemiological study of trypanosomiasis was conducted in the rearing areas of dromedary camels in Mali. According to the parasitological and clinical surveys performed, the overall infection rates were 9.5% (29/305) in Western Sahel (region I) and 4.5% (28/627) in the areas of Tombouctou and Gao (region II). The proportion of contaminated herds was 55% in region I and 68% in region II and in some herds the infection rate exceeded 50%. The surveys showed a trend for increasing parasitological prevalence with age. While it was almost nonexistent in young camels less than one year old, it increased with age and reached a maximum in 2 to 5-year old camels. The authors showed that the infection has a significantly negative effect on PCV and on the overall status of the animals, confirming the pathogenicity of Trypanosoma evansi in dromedary camels. This trypanosome is almost the only species detected in the dromedary camel in Mali and it does not seem to cause infections in other animals reared in the same environment.
