Extended red blood cell antigens and phenotypes in Burkina Faso: potential issues to design local population-sourced red blood cell reagent panels.

To date, 43 blood group systems with 349 red blood cell (RBC) antigens have been recognized. The study of their distribution is useful for blood services to improve their supply strategies for providing blood of rare phenotypes, but also to design indigenous RBC panels for alloantibody screening and identification. In Burkina Faso, the distribution of extended blood group antigens is not known. This study aimed to investigate the extended profiles of blood group antigens and phenotypes of this population and to raise limitations and potential strategies for the design of local RBC panels. We conducted a cross-sectional study that included group O blood donors. Extended phenotyping for antigens in the Rh, Kell, Kidd, Duffy, Lewis, MNS, and P1PK systems was performed using the conventional serologic tube technique. The prevalence of each antigen and phenotype combination was determined. A total of 763 blood donors were included. The majority were positive for D, c, e, and k and negative for Fya and Fyb. The prevalence of K, Fya, Fyb, and Cw was less than 5 percent. The most frequent Rh phenotype was Dce, and the most common probable haplotype was R0R0 (69.5%). For the other blood group systems, the K-k+ (99.4%), M+N+S+s- (43.4%), and Fy(a-b-) (98.8%) phenotypes were the most frequent. Antigenic polymorphism of blood group systems by ethnicity and geography argues for the design and evaluation of population-sourced RBC panels to meet specific antibody profiles. However, some of the specificities identified in our study, such as the rarity of double-dose antigen profiles for certain antigens and the cost of antigen phenotyping tests, are major challenges to overcome.

Feasibility and performance of in-house red blood cell reagents to detect unexpected antibodies in immunized patients in Burkina Faso.

In sub-Saharan Africa, antibody detection tests remain inaccessible because of the high cost and limited shelf life of red blood cell (RBC) reagents. This study aimed at investigating the feasibility and performance of locally prepared RBC reagents for antibody detection in Burkina Faso. We conducted an experimental study comparing commercial RBC panels and a local panel prepared from phenotyped blood donors in Ouagadougou, Burkina Faso. Antibody detection testing was performed by the indirect antiglobulin test using a gel card filtration column in a low-ionic-strength solution. Judgment criteria were the concordance rate and the kappa agreement coefficient of results generated by the two panels. A total of 302 blood donors were phenotyped for the major antigens of the RH, KEL, MNS, FY, JK, LE, and P1PK blood group systems. From this pool of donors, we designed an RBC detection panel that was used to screen for unexpected antibodies in 1096 plasma samples from 832 patients with a history of transfusion and 264 recently delivered or pregnant women with no history of blood transfusion. A positive antibody detection test was observed in 8.1 percent of the samples using the local panel versus 6.4 percent with the commercial panels. A total of 23 samples were negative with the commercial panels and positive with the local panel, while the findings were reversed for four samples. The concordance rate was 97.5 percent, and the kappa agreement coefficient was 0.815. Our results suggest that the development of local RBC panels can be an alternative to commercial panels in countries with limited resources. It could also be a cost-effective intervention, mainly for children under 5 years of age, women of childbearing age, and pregnant women, all of whom are most at risk for malaria and sickle cell disease complications. Blood services could develop and implement appropriate strategies to make phenotyped donor pools available for the design of suitable RBC panels.

[Prevalence of Chronic Complications of Sickle Cell Disease at the Bobo-Dioulasso Teaching Hospital, Burkina Faso]. / Prévalence des complications chroniques de la drépanocytose au CHU de Bobo-Dioulasso, Burkina Faso.

This is a descriptive cross-sectional unicentric study, with a prospective collection of data on the frequency of chronic complications of sickle cell disease in patients monitored at Souro Sanou University Hospital in Bobo-Dioulasso in the department of medicine conducted from April 1, 2017 to July 31, 2018. Patients with confirmed adult sickle cell disease, at least 16 years of age, who had given oral consent, was seen at least twice in the inter-critical period during the study, and who had performed a biological and / or radiological screening for chronic complications. Out of 144 sickle cell patients seen, 79 met our inclusion criteria. The mean age of the patients was 28.8 ± 10.3 years with extremes of 16 and 63 years. Females predominated in 68% of cases (N = 54). Sickle cells were of SC phenotype in 68% of cases, SS in 24%, Sß + in 5% of cases and Sß0 in 3% of cases. The overall prevalence of complications was 54% (43/79), 68% (13/19) in SS individuals and 50% in SC individuals (27/54). The observed chronic complications were ocular, bony, renal, cardiac, cutaneous respectively in 19%, 13%, 6.3%, 5% and 4% of cases, biliary and neurological in 3% each, ENT and pulmonary in 1.3% each. The mean age of patients with at least one chronic complication was 30.9 ± 10.4 years; it was 32.1 ± 10.3 years old in the SC and 25.3 ± 7.8 years old in the SS. Complications were unique in 72%, double in 23% and triple in 5%. The prevalence of chronic complications of sickle cell disease is high in patients with major sickle cell syndrome. Systematic screening and evaluation of organ damage are required to interrupt or delay their evolution.

Il s'est agi d'une étude transversale descriptive unicentrique à collecte prospective des données de la fréquence des complications chroniques de la drépanocytose chez les patients suivis au CHU Sourô-Sanou (CHUSS) de Bobo-Dioulasso dans le département de médecine menée du 1er avril 2017 au 31 juillet 2018. Ont été inclus les patients ayant une drépanocytose majeure confirmée, âgés d'au moins 16 ans, ayant donné un consentement verbal, vus en période intercritique au moins deux fois au cours de l'étude, et ayant réalisé un bilan biologique et/ou radiologique de dépistage des complications chroniques. Sur 144 patients drépanocytaires vus en consultation hématologique, 79 répondaient à nos critères d'inclusion. L'âge moyen des patients était de 28,8 ± 10,3 ans avec des extrêmes de 16 et 63 ans. Le sexe féminin prédominait dans 68 % des cas (n = 54). Les drépanocytaires étaient de phénotype SC dans 68 % des cas, SS dans 24 %, Sß+ dans 5 % des cas et Sß0 dans 3 % des cas. La prévalence globale des complications était de 54 % (43/79). Elle était de 68 % (13/19) chez les drépanocytaires SS et de 50 % chez les drépanocytaires SC (27/54). Les complications chroniques observées étaient oculaires, osseuses, rénales, cardiaques, cutanées, respectivement dans 19, 13, 6,3, 5 et 4 % des cas, biliaires et neurologiques dans 3 % chacune, ORL et pulmonaires dans 1,3 % chacune. L'âge moyen des patients ayant présenté au moins une complication chronique était de 30,9 ± 10,4 ans ; il était de 32,1 ± 10,3 ans chez les SC et de 25,3 ± 8 ans chez les SS. Les complications étaient uniques dans 72 %, doubles dans 23 % et triples dans 5 %. La prévalence des complications chroniques de la drépanocytose est élevée chez les patients porteurs d'un syndrome drépanocytaire majeur au CHUSS. Le dépistage systématique et l'évaluation des dommages aux organes s'imposent pour interrompre ou retarder leur évolution.

Childhood brain tumors in Mali.

to assess epidemiologic and clinical aspects of childhood brain tumors in Mali. a retrospective, descriptive study of children aged 0-15 years with brain tumors, conducted in the pediatrics department of the Gabriel Touré University Hospital Center in Bamako, Mali, from January 31, 2007 to December 3, 2012. In all, 41 cases of brain tumors were recorded during this period (mean: 5.5 years old; range: 1-12 years). Brain tumors were most frequent in the children aged 2-5 years (53.7%) and among boys (53.7%). Late stage at presentation was relatively frequent (34.1%) with a mean time to diagnosis of 10 months. Features of elevated intracranial pressure were the most frequent mode of revelation of primary tumors (26.8%). Supratentorial tumors accounted for 83% of the cases, and gliomas were most frequently (29.3%) identified on computed tomography. Only five patients underwent surgical tumor removal. A broader study including the other hospitals in Bamako could help to assess more accurately the epidemiology of pediatric brain tumors in Mali.

INTRODUCTION: Metastatsic tumoral ascites are characterised by the presence of cancerous cells in peritoneal fluid. They are frequent at an advanced stage of cancer. The goal of our work was to study cytology's contribution in the diagnosis of metastatic ascites at the teaching hospital of Point G. MATERIAL AND METHODS: It was a 3 years retrospective and prospective study, from January 2013 to December 2015. The study included every ascitic samples containing malignant cells at the teaching hospital of Point G. We looked for clinical informations in the patient's fold to find the primary cancer site, the histological diagnosis and the folllowup. RESULTS: We collected data from 213 patients with ascite. Among them, 61 where malignant (28.6 %). Sixty-six percent (66%) of our patients were women. The most represented range age was from 46 to 60 years with a mean of 57.7 years. Housewives were the most frequent among our patients with a rate of 50.8%. Ovarian cancer was the first site with metastatic ascite (26%). It was followed by liver and stomach with respectively 20% and 18%. Ascite was the first clinical manifestation in 36% patients with cancer. It was isolated in 78%. After 6 months, the mortality rate was 76.6%. CONCLUSION: The cytology of ascite liquid is an imortant test for the diagnostic of metastatic ascites.

Radical cystectomy is the standard treatment for bladder tumors infiltrating the bladder muscle, for patients who have tumors without invasion of neighboring organs and without metastasis. After radical cystectomy, the urinary diversion is a challenge for any urologist. Ileal neo bladder is a rare surgery in our country. The ileal neo bladder is recommended in these patients. We report a case of ileal neo bladder in a 42-year-old woman with a bladder tumor. We discuss the clinical, diagnostic and therapeutic aspects.

[Quantitative And Morphological Abnormalities Of Blood Cells Counts Among Customers Received VCT Unit Of The Central Laboratory Of The CHU Of Yopougon]. / Anomalies Quantitatives Et Morphologiques De L'Hemogramme Chez Les Clients Reçus A L'Unite De CDV Du Laboratoire Central Du CHU De Yopougon.

INTRODUCTION: The hematologic abnormalities constitute a reccuring problem in the general population. The HIV infection is a favourable situation for the potentiation of these various hematologic disorders. The aim of the study was to describe the quantitative and qualitative aspects of the three blood lines of our population of study. MATERIAL AND METHOD: It was a prospective cross-sectional study of descriptive type having concerned the people received at the central laboratory of CHU de Yopougon for voluntary tracking from September 1st to September 30th, 2015. RESULTS: We colliged 154 people among whom, a female prevalence was noted with a sex ratio M/F of 0.64. The age bracket from 18 to 29 years was represented (50%) with a 32.94 years median age ± 10 with the 18 and 75 years extremes represented by 50% of single people. The HIV infection prevalence was 20.37%. Anaemia was the most frequent hematologic abnormality (44.44%) its hypochromic microcitic form microcytic (50%) especially. The HIV positive patients had primarily a normochromic normocytic non regenerative anaemia (27.27%). Among HIV positive patients, 23 (65.22%) had a leuconeutropenia combined with lymphopenia at 23 (65.22%) and 12 had bicytopenia which consisted of thrombocytopenia and anaemia. A morphological abnormality of the three blood lines (red blood cells, white blood cells and platelets) was found in 57.41% of our subjects. CONCLUSION: To be in apparent good health, does not exclude the hematologic abnormalities presence. But an HIV infection presence, even in the absence of specific treatment, increases the risk or the degree of severity of these different qualitative and quantitative abnormalities.

INTRODUCTION: Les anomalies hématologiques constituent un problème récurrent dans la population générale. L'infection par le VIH est une situation propice pour la potentialisation de ces différents désordres hématologiques. L'objectif de l'étude était de décrire les aspects quantitatifs et qualitatifs des trois lignées sanguines de notre population d'étude. MATÉRIEL ET MÉTHODE: Etude transversale prospective de type descriptif ayant concerné les personnes reçues au laboratoire central du CHU de Yopougon pour le dépistage volontaire du 1er septembre au 30 septembre 2015. RÉSULTATS: Nous avons colligé 154 personnes parmi lesquelles, une prédominance féminine a été notée avec un sex ratio H/F de 0,64. La tranche d'âge de 18 à 29 ans était la plus représentée (50%) avec un âge moyen de 32,94 ans ± 10 avec les extrêmes de 18 et 75 ans représentée par 50% de célibataires. La prévalence de la séropositivité au VIH était de 20,37%. L'anémie était l'anomalie hématologique la plus fréquente (44,44%) surtout la forme hypochrome microcytaire (50%). Les personnes vivant avec le VIH avaient essentiellement une anémie normochrome normocytaire (27,27%) arégénérative. Une leucopénie avec lymphopénie avait été observée chez 23 (65,22%) tous infectés par le VIH et 12 cas de bicytopénie faite de thrombopénie et d'anémie avaient été observés. Des anomalies morphologiques portant sur les trois lignées sanguines (globules rouges, globules blancs et plaquettes) ont été retrouvées chez 57,41% de nos sujets. CONCLUSION: Etre en bonne santé apparente, n'exclut pas la présence d'anomalies hématologiques. Mais l'association d'une infection par le VIH, même en l'absence de traitement spécifique, augmente le risque ou le degré de sévérité de ces différentes anomalies qualitatives et quantitatives.

[Case study of renal oncocytoma at the Kati hospital]. / Oncocytome renal a propos d'un cas a l'hopital De Kati.

Renal oncocytoma is a rare benign tumor of the kidney. This benign tumor of epithelial origin represents 5% of renal tumors. Preoperative diagnosis is difficult. The final diagnosis can only be made on the anatomical part; even imaging result can often be evocative. We report the case of a 41 year old patient with renal oncocytoma confirmed after radical nephrectomy for renal tumor.

L'oncocytome rénal est une tumeur bénigne rare du rein d'origine épithéliale représentant 5% des tumeurs rénales. Le diagnostic préopératoire est difficile. L'imagerie est souvent évocatrice. Le diagnostic final ne peut être fait que sur la pièce anatomique. L'exploration chirurgicale demeure la règle en absence d'une biopsie rénale pour obtenir un diagnostic histologique précis. Nous rapportons l'observation d'un patient âgé de 41 ans ayant l'oncocytome rénal confirmé après néphrectomie élargie pour tumeur rénale.

[Epidemiology and prognosis of childhood cancers at Gabriel-Touré Teaching Hospital (Bamako, Mali)]. / Épidémiologie et pronostic des cancers pédiatriques au CHU Gabriel-Touré de Bamako (Mali).

UNLABELLED: Cancer today is being treated as a public health problem in Africa, as in developed countries. OBJECTIVE: The aim of this retrospective study was to evaluate the epidemiology and outcome of children treated in the Pediatric Oncology Unit of Gabriel Touré Teaching Hospital in Bamako (Mali), six years after it opened. METHODS: Retrospective study of the files of all children aged 15 and younger diagnosed with cancer and treated by chemotherapy between January 1, 2005, and December 31, 2010. RESULTS: The study included 690 children. Their mean age was 24 months. The time from observation of first symptoms to consultation was less than 3 months in 200 cases (29%), from 3 to 10 months in 256 (37.1%), and more than 10 months in 234 (33.9%). The five most common childhood cancers were malignant non-Hodgkin's lymphoma (NHL) (n=231, 33.5%), retinoblastoma (n=170, 24.6%), nephroblastoma (n=102, 14.8%), acute lymphoblastic leukemia (n=54, 7%), and Hodgkin's disease (n=34, 4%). Six years after the unit opened and after a mean follow-up of 3 years, we recorded 272 deaths (39.4%); at least 238 children are still alive (34.5%), with 180 cases (26.1%) lost to follow-up. CONCLUSION: Childhood cancer survival is still low in Mali, and the rate of loss to follow-up quite high.

[Epidemiological characteristics and prognosis of gastric Cancer in urban areas of Mali]. / Les caracteristiques epidemiologiques et pronostiques du cancer de l'estomac en milieu urbain au Mali.

Stomach cancer remains a public health problem. It is increasingly found in our regions, probably because of the greater availability and improvement of diagnostic facilities.The goal of this work was to study the epidemiological characteristics and prognosis of gastric cancer in the hepato-gastroenterology and general surgery wards of the Gabriel Toure university hospital. METHODS: We conduct a descriptive retrospective study on patients from June 2008 to May 2009, and the enrollment of patients lasted from June 2009 to May 2010. RESULTS: We examined the records of 68 cases of gastric cancer in 115 cases of digestive cancers a frequency of 59.1%.The mean age of patients was 56.51 ± 14.8 years with extremes of 27 and 90 years. The sex ratio was 1.6 in favor for men. The social and professional groups (housewives and farmers) were the most represented with 50 cases (73.5%). Salting, smoking, consumption of tô (cereal dough) with potash were the most found risk factors in 80.9%, 94.2% and 80.6% of cases respectively. The localization of antro-pyloric site was most represented (60.3%). Adenocarcinoma was the most common histological type (94.1%), one case of Gastrointestinal Stromal Tumor (GIST), two cases of non hodgkin malignant lymphoma were found.The curative surgery was performed in 8.9% of our patients. The overall survival rate after any surgery with two-year follow-up was 9.4%. Post curative surgery survival was 83.3% at two years follow-up. CONCLUSION: Stomach cancer is common in our context, but its management is suffering from delayed diagnosis.

Le cancer de l'estomac reste un problème de santé publique.Il est de plus en plus constaté dans nos régions, du fait probablement de la disponibilité plus importante des moyens diagnostiques.Le but de ce travail était d'étudier les caractéristiques épidémiologiques et pronostiques du cancer de l'estomac dans les services d'hépato-gastroentérologie et de Chirurgie générale du CHU Gabriel Touré.Il s'agissait d'une étude rétrospective descriptive ayant porté sur les malades colligés de juin 2008 à mai 2009 et l'étude des dossiers de ces malades a duré de juin 2009 à mai 2010. Nous avons consulté les dossiers de 68 cas de cancers de l'estomac sur 115 cas de cancers digestifs soit une fréquence de 59,1%. L'âge moyen des patients était de 56,51±14,8 ans avec des extrêmes de 27 et 90 ans .Le sexratio était de 1,6 en faveur des hommes. Les couches socioprofessionnelles (ménagères et cultivateurs) étaient les plus représentées avec 50 cas soit 73,5%. La salaison, le fumage, la consommation de tô (pâte de céréales) avec potasse ont été les facteurs de risque les plus retrouvés dans respectivement 80,9%;94,2% et 80,6% des cas. Le siège antro-pylorique a été plus représenté (60,3%). L'adénocarcinome a été le type histologique le plus fréquent (94,1%), un cas de tumeur stromale, deux cas de lymphome malin non hogdkinien ont été retrouvés. La chirurgie à visée curative a été réalisée chez 8,9% de nos patients. Le taux de survie globale après toute chirurgie confondue à deux ans de suivi a été de 9,4%. La survie post chirurgie curative a été de 83,3% à deux ans de suivi. CONCLUSION: Le cancer de l'estomac est fréquent dans notre contexte mais sa prise en charge souffre du retard diagnostique.

[Bifocal Buruli ulcer: multiple cephalic lesions after initiation of medical treatment]. / Ulcère de Buruli à début bifocal: multiples lésions céphaliques après instauration du traitement médical.

BACKGROUND: Buruli ulcer (BU) denotes a cutaneous infection by Mycobacterium ulcerans endemic in certain tropical and subtropical regions. Treatment may be either medical and surgical or else purely medical for early lesions. The literature contains reports of several cases of transient aggravation of BU following initiation of medical treatment. We report a case observed in the Ivory Coast, one of the areas with the highest prevalence of BU worldwide. The distinguishing features of our case are the early onset of this paradoxical reaction and the multiple cephalic site of lesions. PATIENTS AND METHODS: A 4-year-old child with no prior medical history was referred for two painless ulcerative cutaneous nodules. Incubation of samples from the edges of these lesions revealed the presence of acid-alcohol resistant bacilli (AARB), which were shown by PCR to be M. ulcerans, the causative agent in BU. Treatment consisted of levofloxacin (100mg/d) and rifampicin (150mg/d) for 8weeks. After 7days of medical treatment, seven painless nodules appeared on the patient's scalp. Further PCR for these lesions confirmed the presence of M. ulcerans. The same medical therapy was maintained and after 54days of treatment, all lesions had been healed. DISCUSSION: The originality of this case rests on two features: the bifocal aspect of the lesions, which is uncommon, and the early development of cephalic predominance that occurred after the start of drug treatment. While cases of lesions secondary to initiation of medical therapy have already been described, such lesions generally occurred after at least 2months of treatment and did not involve the head.

[Colon amyloidosis secondary to tuberculosis: Case report and review of the literature]. / L'amylose colique secondaire a la tuberculose: A propos d'une observation et revue de la litterature.

The authors report the first case of amyloidosis diagnosed by histology and documented in Mali. The patient was a young lady of 31 years old who was hospitalized in internal medicine at the University Hospital of "Point G" for edema and ascites syndrome. She had a history of diarrhea, fever, vomiting, exercise dyspnea and diffused abdominal pain. The biological assessment such as HIV serology was negative. The research of Mycobacterium tuberculosis in sputum was positive. The diagnosis hypothesis of amyloidosis has been evoked and a biopsy of the rectal mucosa has been performed. The fragments showed by histology an acellular band between the basal membrane and the periglandular area. This band was stained in red by Rouge Congo. That confirmed the diagnosis of amyloidosis.

Les auteurs rapportent le premier cas d'amylose diagnostiqué à l'histologie et documenté au Mali. Il s'agissait d'une jeune dame de 31ans ayant été hospitalisée en médecine interne au CHU du «Point G" pour syndrome oedemato-ascitique. Elle a comme antécédent: une diarrhée, une fièvre, des vomissements, une dyspnée d'effort et des douleurs abdominales diffuses. Le bilan biologique y compris la sérologie VIH était sans particularité. La recherche de BAAR dans les crachats était positive. L'hypothèse diagnostique d'amylose a été évoquée et une biopsie de la muqueuse rectale a été effectuée. Les fragments présentaient à l'histologie une bande acellulaire entre la membrane basale et la zone périglandulaire. Cette bande a été colorée en rouge par le rouge Congo. Ceci a permis de confirmer le diagnostic d'amylose.

[Atypical fibrous epulis: Surgical treatment of 1 case]. / Epulis fibreuse remaniee: Prise en charge chirurgicale d'un cas.

Benign tumors are frequently encountered pathologies on the oral mucosa. They comprise a number of different lesions, including fibrous epulis. Its diagnosis is only possible by histological examination. We are presenting the case of a patient who consulted for an externalized maxillary swelling. Clinical examination showed an oval, painless swelling of solid consistency, independent of the alveolar bone, covered by a fibrous grayish membrane, prolonging the gingival fibro-mucosa at the vestibular level. The treatment was surgical excision of the tumor. Histological examination concluded that there was a lack of cytonuclear atypia and retained the diagnosis suggesting atypical fibrous epulis. We reviewed the clinical data, diagnosis and treatment of this type of tumor.

Les tumeurs bénignes sont des pathologies fréquemment rencontrées au niveau de la muqueuse buccale. Elles regroupent un ensemble de lésions dont l'épulis fibreuse. Le diagnostic positif de cette dernière n'est confirmé que par l'examen histologique.Nous rapportons le cas d'un patient ayant consulté pour une tuméfaction maxillaire extériorisée. L'examen clinique a permis de trouver une tuméfaction de forme ovalaire, indolore, de consistance ferme n'intéressant pas l'os alvéolaire, recouverte par une membrane grisâtre d'aspect fibreux, prolongeant la fibro-muqueuse gingivale au niveau vestibulaire. Le traitement réalisé fut l'exérèse chirurgicale de la tumeur. L'examen histologique a conclu en une absence d'atypie cytonucléaire et a retenu le diagnostic d'épulis fibreuse remaniée. Nous avons passé en revue les données cliniques, diagnostiques et thérapeutiques de ce type de tumeur.

[Upper gastrointestinal endoscopy during Kaposi's sarcoma to the Point G Hospital, Bamako (Mali): case study 20]. / Endoscopie Digestive Haute Au Cours De La Maladie De Kaposi Au CHU Du Point G, Bamako(Mali) : Etude De 20 Cas.

INTRODUCTION: Since the advent of HIV, Kaposi's sarcoma has become one of the most common opportunistic infections and the first cancer in patients with HIV. This cancerous disease occurs most often on the skin but also the viscera. Digestive localization was often observed during the search for other locations before the cutaneous form. No studies in Mali has focused on the upper gastrointestinal location. OBJECTIVES: To describe the epidemiological and clinical aspects of Kaposi's sarcoma in the upper gastrointestinal endoscopy. METHODS: This was a retrospective descriptive study from June 2005 to February 2009 in the center of endoscopy of the Point G Hospital including all patients seen in upper gastrointestinal endoscopy during the study period. RESULTS: 20 cases were reported from a total of 5068 endoscopy performed during this period a frequency of 0.39% hospital. These 20 cases were identified in all 31 patients with cutaneous localization of Kaposi's sarcoma is a frequency of 64.5%. The sex ratio was equal to 0.81. The average age was 36.8 years ± 8.92 years. The stomach and esophagus were found most locations. All patients were HIV positive. The CD4 count below 200 cells/mm3 was observed in 95% of patients.

Can visual cervical screening be sustained in routine health services? Experience from Mali, Africa.

OBJECTIVE: To assess the feasibility of sustaining visual cervical screening and treatment services in Mali, and to evaluate their performance and impact in improving the provision of cervical cancer control, following an initial cross-sectional study. DESIGN: Descriptive study. SETTING: Bamako area, Mali. POPULATION: Women aged 30-59 years. METHODS: Routine visual screening and treatment services were organised through two hospitals and 14 health centres. Patients with positive visual screening tests underwent colposcopy and/or directed biopsies, and ablative or surgical excision treatment was offered to those with cervical intraepithelial neoplasia (CIN). MAIN OUTCOME MEASURES: Test positivity, detection and treatment rates for CIN and the sustainability of screening services. RESULTS: Of the 14,141 women screened, 1682 (11.9%) were positive and were referred for further investigations and treatment. Over 75% of the screen-positive women underwent colposcopy and/or biopsy. CIN 1 was detected in 383 women, CIN 2 in 88, CIN 3 in 37 and invasive cervical cancer in 497. More than 80% of women with CIN and 35% of those with invasive cancer received treatment. The test performance characteristics and treatment coverage of routine screening were similar to those observed in the preceding cross-sectional study. CONCLUSION: Visual screening and treatment services are sustainable and effective in improving cervical cancer control provision by health services in Bamako, Mali. It is essential to organise and sustain several point-of-care services in order to extend cervical cancer prevention in low-income African countries.

Hodgkin lymphoma at the paediatric oncology unit of gabriel touré teaching hospital, bamako, mali: 5-year experience.

Introduction. The aim of this retrospective, unicentric study over 5 years is to describe the epidemiologic, pathologic, clinic and therapeutic aspects of children treated for Hodgkin lymphoma in our paediatric oncology unit. Patients and Methods. From January 2005 to December 2009, all children under 18 years of age, with Hodgkin lymphoma were included in this study. The treatment protocol was the GFAOP (Groupe Franco-Africain d'Oncologie Pédiatrique) Hodgkin lymphoma treatment protocol. Results.
