[Radiochemotherapy for the treatment ofmuscle invasive bladder tumors in a west african radiotherapy service]. / Radiochimiotherapie pour le traitement des tumeurs de vessie infiltrant lemuscle dans un service de radiotherapie ouest africaine.

OBJECTIF: The aim of this study was to describe the results of radiochemotherapy in patients after transurethral resection of muscle invasive bladder tumors. MATERIAL AND METHODS: A retrospective study from May 2014 to May 2016 in the radiotherapy department of the Mali Hospital. Have been included, all patients with bladder cancer infiltrating the muscle. Secondary cancers of the bladder and metastatic forms have been excluded from our study. Transurethral resection of bladder was performed. Neoadjuvant chemotherapy with paclitaxel- carboplatin was administered every three weeks in all patients, then external phototherapy 6 MV at a dose of 66 Gy due to 2 Gy of 5 sessions per week 6MV photon of external beam radiotherapy at a dose of 66 Gy due to 2 Gy of 5 sessions per week associated with concomitant cisplatin at dose of 40mg / m2 / week. RESULTS: Eight patients were included in ourstudy. The average age of 53.75 ± 14.84 years. The male sex was predominant 87.5% (n = 7). The history of chronic smoking wasfound in four patients. The main carcinogenic risk factor identified in our patients was urogenital bilharzia (6 cases / 8).The histological type found was urothelial carcinomain 12.5% (n = 1) and invasive squamous cell carcinomain 87.5% (n = 7). Transurethral resection of the tumor was performed in 62.5% (n = 5). Endoscopic biopsy was performed in 37.5% (n = 3). The tumor was classified pT2N0M0 in 50% (n = 4), pT3aN0M0 in 37.5% (n = 3) and pT3bN0M0 in 12.5% (n = 1). Neoadjuvant chemotherapy with paclitaxel - carboplatin every three weeks was administered to all patients. The results of radiochemotherapy (see Table: evolution). CONCLUSION: Concomitant radiochemotherapy is a conservative curative treatment that can be proposed as a replacement for cystectomy, for non-metastatic infiltrating tumors after the most complete endoscopic resection.

[Epidemiological and prognostic aspects of obstructive renal deficiency in the nephrology department of the Point "G" hospital, Bamako, Mali]. / Aspects epidemiologiques et pronostiques de l'insuffisance renale obstructive dans le service de nephrologie du CHU du Point G, Bamako, Mali.

INTRODUCTION: Obstructive renal failure or obstructive uropathy is an entity defined by the simultaneous presence of impaired renal function and dilated urinary excretory pathways in medical imaging. It accounts for 2 to 10% of the causes of acute renal failure (ARF). The purpose of this work was to evaluate the prevalence of this condition in our department. METHOD: This was a retrospective study conducted from January 1, 2017 to June 30, 2018 in the said department. The parameters studied were age, sex, etiology, type of renal failure, actions performed, surgical results of the procedure, creatinine level before and after management, and death rate. RESULTS: obstructive renal failure accounted for 7.32% of all hospitalizations during the study period. The sex ratio was 1.86 in favor of men. The average age was 48.99 ± 6.81 years with extremes of 7 and 102 years. The etiologies were dominated by lithiasis (43.4%). Renal failure was acute and chronic in 20.5% and 54.2% of cases, respectively. It was indeterminate in 25.3% of cases. The obstructive character of renal failure has been confirmed in medical imaging. Lithiases accounted for 43.4% of cases. For therapeutic management, our patients received urinary catheterization (38.6%), nephrostomy (34.9%), urological surgery (22.9%) and hemodialysis (22%). The evolution was favorable in 59% of the cases. CONCLUSION: Obstructions of the upper urinary tract are becoming more frequent in our medical practice. They occur mainly in patients with lithiasis. There is a large proportion of kidney failure requiring hemodialysis.

INTRODUCTION: L'insuffisance rénale obstructive ou encore uropathie obstructive est une entité définie par la présencesimultanée d'une altération de la fonction rénale et d'une dilatation des voies excrétrices urinaires à l'imageriemédicale. Elle représente 2 à 10% des causes d'insuffisance rénale aiguë (IRA). L'objectif de ce travail était de déterminer la prévalence de cette affection dans notre service. MÉTHODE: Il s'agissait d'une étude rétrospective réalisée du 1er janvier 2017 au 30 juin 2018 dans le service de néphrologie du CHU du Point G.Ont été inclus, tous les patients hospitalisés dans le service durant la période d'étude et ayant un dossier médical exploitable. Les paramètres étudiés étaient l'âge, le sexe, l'étiologie, le type d'insuffisance rénale, les gestes réalisés, les résultats chirurgicaux de la procédure, le taux de créatinine avant et après la prise en charge et le taux de décès. RÉSULTAT: Durant la période d'étude, 83 patients répondaient aux critères d'inclusion sur les 1133 patients hospitalisés, soit 7, 32%.Le sex-ratio était de 1,86 en faveur des hommes. L'âge moyen était de 48,99±6,81 ans avec des extrêmes de 7 et 102 ans. A l'admission 97,6% des patients avaient une créatininémie augmentée. La créatininémie moyenne était de 1284,087 µmol/l avec des extrêmes de 506 et 2063 µmol/l. La créatininémie moyenne après traitement était de 579,605 µmol/l. L'échographie de l'arbre urinaire réalisée chez tous nos patients a montré une hydronéphrose et une urétérohydronéphrose dans respectivement 61,5% et 38,5% des cas. La tomodensitométrie abdomino-pelvienne réalisée chez 42 patients, montrait une urétérohydronéphrose bilatérale dans 50% des cas. La lithiase urétérale et les séquelles bilharziennes étaient les plus fréquemment retrouvées à la TDM avec 23,53% chacune. L'infection urinaire était présente dans 59,7% des cas et le germe isolé était Escherichia coli dans 32,8% des cas. Les étiologiesétaient dominées par les lithiases (43,4%). L'insuffisance rénale était aiguë et chronique dans respectivement 20,5% et 54,2% des cas. Elle était indéterminée dans 25,3% des cas. La prise en charge thérapeutique comportait le sondage urinaire (38,6%), la néphrostomie percutanée (34,9%), la chirurgie urologique (22,9%) et l'hémodialyse (22%).L'évolution a été favorable dans 59,04% des cas dont 20,48% des cas de guérison complète, 14, 46% des cas d'amélioration et 24,10% des cas ont été transférés. Le taux de mortalité était élevé soit 36,14%. CONCLUSION: les obstructions du haut appareil urinaire sont de plus en plus fréquentes dans notre pratique médicale. Elles sont essentiellement d'origine lithiasique. On compte une importante proportion d'insuffisance rénale nécessitant une prise en charge en hémodialyse.

Smooth muscle of the male pelvic floor: An anatomic study.

Knowledge of the anatomy of the male pelvic floor is important to avoid damaging the pelvic floor muscles during surgery. We set out to explore the structure and innervation of the smooth muscle (SM) of the whole pelvic floor using male fetuses. We removed en-bloc the entire pelvis of three male fetuses. The specimens were serially sectioned before being stained with Masson's trichrome and hematoxylin and eosin, and immunostained for SMs, and somatic, adrenergic, sensory and nitrergic nerve fibers. Slides were digitized for three-dimensional reconstruction. We individualized a middle compartment that contains SM cells. This compartment is in close relation with the levator ani muscle (LAM), rectum, and urethra. We describe a posterior part of the middle compartment posterior to the rectal wall and an anterior part anterior to the rectal wall. The anterior part is split into (1) a centro-levator area of SM cells localized between the right and left LAM, (2) an endo-levator area that upholsters the internal aspect of the LAM, and (3) an infra-levator area below the LAM. All these areas are innervated by autonomic nerves coming from the inferior hypogastric plexus. The core and the infra-levator area receive the cavernous nerve and nerves supplying the urethra. We thus demonstrate that these muscular structures are smooth and under autonomic influence. These findings are relevant for the pelvic surgeon, and especially the urologist, during radical prostatectomy, abdominoperineal resection and intersphincteric resection. Clin.

Impact of seasonal malaria chemoprevention in children aged 3 to 59 months in the Kangaba and Kolokani health districts between 2013 and 2015.

INTRODUCTION: Malaria is a public health problem in Mali. Seasonal chemo prevention (SCP) is of particular importance, hence its introduction by the WHO since 2012 in children aged 3 to 59 months from the start of the transmission season. This study aims to demonstrate the impact of SCP on malaria in the health districts of Kangaba and Kolokani. MATERIALS AND METHODS: Our retrospective study was carried out from 2013 to 2015 in the health districts of Kangaba and Kolokani using the databases of the NGO AMCP / ALIMA. Data from 2014 and 2015 were compared to data from 2013. RESULTS: The number of malaria cases in children under 5year in the area covered by the SCP shows a considerable decrease in Kangaba of 52% in 2014 and 49% in 2015, compared to the reference period being the year 2013. In Kolokani the decrease is 57% in 2014 and 40% in 2015 compared to the year 2013. Compared to deaths, a decrease of 50.5% was recorded in 2014 and 60.4% in 2015 compared to the year 2013, i.e. 51 and 61 fewer deaths compared to 2013, respectively, in health facilities. CONCLUSION: The SCP had made it possible to reduce significant mortality and malaria morbidity in the two health districts of Kangaba and Kolokani.

INTRODUCTION: le paludisme est un problème majeur de santé publique au Mali. La chimio prévention saisonnier a une importance particulière d'où son instauration par l'OMS depuis 2012 chez les enfants de 3 à 59 mois à partir du début de la saison de transmission. Cette étude vise à démontrer l'impact de la CPS sur le paludisme dans les districts sanitaires de Kangaba et de Kolokani. MATÉRIELS ET MÉTHODES: Notre étude rétrospective a été réalisée de 2013 à 2015 dans les districts sanitaires de Kangaba et de Kolokani en utilisant les bases de données de l'ONG AMCP/ALIMA. Les données de 2014 et 2015 ont été comparés à ceux de 2013. RÉSULTATS: Le nombre de cas de paludisme chez les enfants de moins de 5 ans dans la zone couverte par la CPS montre une baisse considérable à Kangaba de 52% en 2014 et 49% en 2015, par rapport à la période de référence étant l'année 2013. A Kolokani la baisse est de 57% en 2014 et 40% en 2015 par rapport à 2013. Par rapport aux décès, une baisse de 50,5% a été enregistrée en 2014 et 60,4% en 2015 par rapport à 2013, soit respectivement 51 et 61 décès en moins comparé à 2013, dans les structures de santé. CONCLUSION: La CPS avait permis une réduction de la mortalité importante et de la morbidité palustre dans les deux districts sanitaires de Kangaba et de Kolokani.

[Neoadjuvant chemotherapy in locally advanced cervical cancer in patients receiving a concomitant chemoradiotherapy in a low income country]. / Chimiotherapie neo adjudante dans les cancers localement avances du col uterin chez des patientes recevant une radiochimiotherapie concomitante dans pays aux ressources limitees.

PURPOSE: Delays to access to radiotherapy are long in our context. The purpose of this study was to analyze the effect of neoadjuvant chemotherapy to concomitant chemoradiotherapy in locally advanced cervical cancers. PATIENTS AND METHODS: We conducted a retrospective study from April 2014 to April 2016 at the radiotherapy center of "Hopital du Mali" in Bamako, Mali. Patients were allocated according to age, histological type, tumor size and the 2002 classification of the FIGO. Experimental protocol was the administration of a neoadjuvante chemotherapy with association of Paclitaxel 175mg/m2 + Carboplatine AUC 5 every 3 weeks and radiothérapy cure with avec linac 6 MV at 70 Gy due to 5 sessions of 2 Gy per week associated with a concomitant chemotherapy with cisplatin at 40 mg/m2/week. The clinical response was assessed at the end of neoadjuvant chemotherapy and of concomitant chemoradiotherapy. RESULTS: Thirty patients were included in the study. The mean age was 53.63 ± 8.9 years. The mean size of the tumor was 5.17 cm (2 to 7 cm). According to the 2002 classification of the FIGO stages IIB were 33% (n = 10); IIIB were 57% (n = 17) and IVA were 10% (n = 3). Clinical evaluation at the end of neoadjuvant chemotherapy found: complete response 17 % (n = 5), partial response 10% (n = 3) and stable disease 73 % (n = 22). Evaluation at the end of the concomitant chemoradiotherapy had found the complete response in 90% (n = 27) and stable disease in 10% (n = 3). CONCLUSION: Neoadjuvant chemotherapy to concomitant chemoradiotherapy in locally advanced cervical cancer allows stabilization of the tumor and improves local control. Due to long delays to access to radiotherapy treatment in our context; neoadjuvant chemotherapy is an alternative to stabilize the disease and prevent distant metastasis from locally advanced cervical cancers.

OBJECTIF: Les délais d'attente pour accéder à la radiothérapie sont longs dans note contexte. L'objet de cette étude était d'analyser le résultat de la chimiothérapie néo adjuvante à la radiothérapie dans les cancers localement avancés du col utérin. PATIENTS ET MÉTHODES: Nous avons réalisé une étude rétrospective allant d'avril 2014 à avril 2016 au centre de radiothérapie de l'hôpital du Mali. Les patients ont été regroupés selon l'âge, le type histologique, la taille de la tumeur, la classification de la FIGO 2002. Le schéma thérapeutique était une chimiothérapie néo adjuvante associant Paclitaxel 175 mg/m2 et Carboplatine AUC 5 toutes les 3 semaines suivie d'une radiothérapie avec linac 6 MV à la dose de 70 Gy en raison de 5 séances de 2 Gy par semaine faite concomitamment à une chimiothérapie avec du cisplatine à la dose de 40 mg/m2/semaine. La réponse clinique était évaluée à la fin de la chimiothérapie néoadjuvante et de la radiochimiothérapie concomitante. RÉSULTATS: Trente patientes ont été incluses dans l'étude. L'âge moyen était de 53.63 ± 8.9 ans. La taille moyenne de la tumeur était de 5,17 cm (2 à 7 cm). Selon la classification FIGO 2002, 10 (33%) étaient en stade IIB distal, 17 (57%) étaient en stade IIIB et 3 (10%) en stade IVA. L'évaluation clinique à la fin de la chimiothérapie néo adjuvante avait retrouvé 17 % de réponses complètes (n=5), 10% de réponses partielles (n=3) 73 % d'évolutions stables (n=22). L'évaluation à la fin de la radiochimiothérapie concomitante avait trouvé une réponse complète chez 27 patientes (90%) et une maladie stable chez 3 (10%). CONCLUSION: La chimiothérapie néo adjuvante à la chimioradiothérapie concomitante dans les cancers localement avancés du col utérin permet la stabilisation de la tumeur et améliore le control local. En raison des délais d'attente longs pour accéder à la radiothérapie, la chimiothérapie néo adjuvante est une alternative pour stabiliser la maladie et réduire le risque de métastases à distance des cancers du col utérin localement avancés.

[The Ileal Neobladder With The Hautmann Technic At The Urology Depatment Of University Hospital Pr. Bocar S. SALL Of Kati]. / Le Remplacement De Vessie Selon La Technique De Hautmann Au Service D'Urologie Du Chu Pr. Bocar S. SALL De Kati.

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.

La cystectomie totale constitue le traitement de référence des tumeurs de vessie infiltrant le muscle vésical, pour les patients qui ont une tumeur sans envahissement des organes voisins et sans métastase. Après la cystectomie, la dérivation des urines est un challenge pour tout urologue. Le remplacement de vessie est un geste rarement réalisé dans notre pays. Un remplacement de vessie par l'intestin est recommandé chez ces patients. Nous rapportons un cas de remplacement de vessie chez une femme de 42 ans ayant une tumeur de vessie. Nous discutons les aspects cliniques, diagnostiques et thérapeutiques.

Screening and management of HIV infection in pregnant women in Dakar.

OBJECTIVES: To assess the feasibility and results of the implementation of systematic HIV screening of pregnant women and antiretroviral (ARV) treatment for those found to be HIV-positive and their newborns at the IHS Gynecology-Obstetrics Department in Dakar, Senegal. PATIENTS AND METHODS: This cross-sectional prospective study took place in 2014-1016 and examined the results of screening pregnant women for HIV during their prenatal consultations and treating those found to be HIV-positive and their infants with ARV. RESULTS: HIV screening was routinely proposed to the 1616 pregnant women attending antenatal clinics, and 93.9 % accepted. The test was positive for 5 of these women, for an HIV prevalence of 0.3 % of pregnant women. In addition, another 23 HIV-positive pregnant women were referred to the IHS for their prenatal care and delivery, for a total of 28 women with HIV. Their mean age was 30 years, their mean parity 1.6, and all had HIV-1. Triple therapy was initiated for all HIV-positive pregnant women, in line with the WHO guidelines' "B + option", currently adopted by Senegal. During follow-up, only 35.7 % of the women had access to a viral load assay. The outcome of pregnancy was favorable in 91.6 % of cases; 72.2% of the women had vaginal deliveries. All live-born infants were given antiretroviral prophylaxis at birth. The mode of breastfeeding used was mainly exclusive protected breastfeeding (72.2 %). During postnatal follow-up, 2 of the 17 live-born infants were lost to follow-up, and 15 had PCR testing for HIV, which was positive in only 1 case, for a transmission rate of 6.6 %. CONCLUSION: The systematic offer and performance of HIV testing in all pregnant women is feasible and acceptable. Good organization of care can provide ARV treatment for all HIV-positive pregnant women and their newborns. The accessibility of viral load testing and of PCR screening for neonates still requires improvement.

[Prevalent Of Echocardiography Anomaly In Chronic Hemodialysis Patients At The Point G Hospital]. / Prevalence Des Anomalies Echocardiographiques Chez Les Hemodialyses Au Chu Point G.

INTRODUCTION: Cardiovascular abnormalities are frequent and often early, severe and masked in patients with renal impairment. These cardiovascular complications are the main causes of death in hemodialysis patients. The diagnosis of these cardiovascular anomalies by cardiac ultrasound allows the individualization of patients at high cardiovascular risk. We conducted this study to evaluate the echo-cardiographic aspects of chronic hemodialysis in the nephrology and hemodialysis department of the G-Point CHU. METHODS: This is a retrospective study of chronic renal failure patients who have undergone extra-renal treatment for 6 months or more from January 1, 2011 to December 31, 2012. Results: During this study, 83 files were retained The sex ratio was 1.51 in favor of men. The average age of patients was 48 years old. HTA (59%) and tobacco (43.3%) remain the dominant risk factors. Vascular nephropathy was the leading cause of CKD, 44.6%. Echo-cardiac abnormalities are dominated by cavitary dilatation (78.3%), LVH (41%), cardiac dysfunction (83.2%), valvular lesion (30.1%), and pericarditis (22,9%). The cardiovascular complications were LVH (41%), hypertension (25.3%) and dilated cardiomyopathy (9.7%). The evolution was favorable for 73.5% of the patients, the mortality represented 8.4% with various complication (18.1%).

INTRODUCTION: les anomalies cardiovasculairessont fréquentes et souvent précoces, sévères et masquées chez les patients insuffisants rénaux. Ces complications cardiovasculaires sont les principales causes de mortalités et de morbidité chez les hémodialysés. Le diagnostic de ces anomalies cardiovasculaires par l'échographie cardiaque permet l'individualisationdes patients à haut risque cardio vasculaire. L'objectif de cette étude était d'évaluer les aspects échocardiographiques chez les hémodialyses chroniques dans le service de néphrologie et d'hémodialyse du CHU du point G. MÉTHODES: Il s'agit d'une étude rétrospective du 1er janvier 2011 au 31 décembre 2012 et a concerné les insuffisances rénales chroniques ayant bénéficié d'une épuration extra-rénale depuis6mois. RÉSULTATS: Au cours de cette étude 83 dossiers étaient retenus. Le sex ratio était de 1,5 en faveur des hommes. L'âge moyen des patients était de 48 ans. L'HTA (59%), le tabac (43,3%) restent les facteurs de risque dominant. La néphropathie vasculaire a été la principale cause d'IRC soit 44,6%.Les anomalies échocardiographiques sont dominées par la dysfonction cardiaque (83,2%), ladilatation cavitaire (78,3%), l'HVG (41%), la lésion valvulaire (30,1%), et l'épanchement péricardique (22,9%). Les complications cardiovasculaires étaient l'HTA (67.%), lacardiomyopathie dilatée (49,7%) et l'HVG (41%). L'évolution était favorable chez 73,5% des patients, la mortalité représentait 8,4% avec complication diverse (18,1%).

Inside-out autologous vein grafts fail to restore erectile function in a rat model of cavernous nerve crush injury after nerve-sparing prostatectomy.

Some autologous tissues can restore erectile function (EF) in rats after a resection of the cavernous nerve (CN). However, a cavernous nerve crush injury (CNCI) better reproduces ED occurring after a nerve-sparing radical prostatectomy (RP). The aim was to evaluate the effect on EF of an autologous vein graft after CNCI, compared with an artificial conduit. Five groups of rats were studied: those with CN exposure, exposure+vein, crush, crush+guide and crush+vein. Four weeks after surgery, the EF of rats was assessed by electrical stimulation of the CNs. The intracavernous pressure (ICP) and mean arterial pressure (MAP) were monitored during stimulations at various frequencies. The main outcome, that is, the rigidity of the erections, was defined as the ICP/MAP ratio. At 10 Hz, the ICP/MAP ratios were 41.8%, 34.7%, 20.9%, 33.9% and 20.5%, respectively. The EF was significantly lower in rats if the CNCI was treated with a vein graft instead of an artificial guide. Contrary to cases of CN resection, autologous vein grafts did not improve EF after CNCI. In terms of clinical use, the study suggests to limit an eventual use of autologous vein grafts to non-nerve-sparing RPs.

[Sickle cell anemia and transfusion safety in Bamako, Mali. Seroprevalence of HIV, HBV and HCV infections and alloimmunization belonged to Rh and Kell systems in sickle cell anemia patients]. / Sécurité transfusionnelle et drépanocytose à Bamako, Mali. Séroprévalence des infections à VIH, VHB, VHC et allo-immunisation anti-Rh et Kell chez les drépanocytaires.

Red cell transfusion is one of the main treatments in sickle cell disease. However there are potential risks of blood transfusions. In order to propose strategies to improve blood safety in sickle cell disease in Mali, we conducted a prospective study of 133 patients with sickle cell anemia recruited at the sickle cell disease research and control center of Bamako, November 2010 to October 2011. The study aimed to determine the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections by serum screening and the frequency of red cell alloimmunization before and after blood transfusion. The diagnosis of sickle cell syndrome was made by HPLC, the detection of markers of viral infection was performed by ELISA, and the diagnosis of alloimmunization was conducted by the Indirect Coombs test. Prevalence of viral infections observed at the time of enrolment of patients in the study was 1%, 3% and 1% respectively for HIV, HBV and HCV. Three cases of seroconversion after blood transfusion were detected, including one for HIV, one for HBV and one another for HCV in sickle cell anemia patients. All these patients had received blood from occasional donors. The red cell alloimmunization was observed in 4.4% of patients. All antibodies belonged to Rh system only. Blood transfusion safety in sickle cell anemia patients in Mali should be improved by the introduction of at least the technique for detecting the viral genome in the panel of screening tests and a policy of transfusions of blood units only from regular blood donors.

[Relationship between glomerular filtration rate, uric acid, and parathyroid hormone in children]. / Relation entre débit de filtration glomérulaire, parathormone et acide urique chez l'enfant.

INTRODUCTION: Parathyroid hormone (PTH) and uric acid (UA) levels increase early during chronic kidney disease (CKD). The objective of this study was to evaluate the relationship between these two parameters at different stages of pediatric CKD. PATIENTS AND METHODS: One hundred patients (range, 5-18 years) were included in this retrospective study: they had undergone renal exploration with a direct measurement of the glomerular filtration rate (GFR) using the reference standard (i.e., inulin clearance, Cin) and presented with increased circulating levels of PTH and/or UA. RESULTS: GFR was normal in 39% of patients, with UA increased in 44% and PTH in 75% of them. Interestingly, 29% of the children with increased PTH levels had a strictly normal GFR (i.e., above 90 mL/min/1.73 m(2)). An inverse association was found between UA and GFR (r=-0.452, P ≤ 0.0001) as well as between PTH and GFR (r=-0.226, P=0.024). The same negative relationships were found between UA and PTH (r=-0.266, P=0.007), and between UA and the phosphate reabsorption rate (r=-0.415, P<0.001). DISCUSSION: Since hyperuricemia was found at all stages of CKD, an early silent tubular impairment can be discussed to explain these findings. The early increase in PTH levels during CKD has not been described by all authors, with North American studies describing rather late increased PTH levels during CKD. Prospective studies are required to confirm these data and evaluate the role of UA in the pathophysiology of the mineral disorders observed during CKD.

[Loco-regional anesthesia practices in 1261 cases]. / Pratique de l'anesthesie loco-regionale a propos de 1261 cas.

GOAL: The aim of this study was to take stock of the practice of the loco-regional anesthesia (LRA) at the University Hospital Center of Point G from January 2004 to December 2008. MATERIALS AND METHOD: This is a retrospective study, assessing the practice of LRA. The demographic data, the surgery, the technical characteristics of the procedure made, the type of local anesthetic used, adverse events were evaluated. RESULTS: The LRA involved 1261 patients - 8.30% of the total number of surgical procedures occurring during the studied period. The American Society of Anesthesiology (ASA) classification was used for the evaluation of patients in scheduled surgery. The patients belonged to class 1 (50.40%) and Class 2 (49.60%). The main surgical procedures were: 26.20% surgical prostatic adenomectomy, 23.80% of caesarean section, and the fistulogram test for 19.04%. The LRA techniques performed were: spinal anesthesia, 87.60%, epidural anesthesia, 12%. Three hundred and three adverse events (24%) have been reported, three (1%) of them have resulted in the death of the patient. The incidence of arterial hypotension was 94.40%, and 4.6% for bradycardia. The three heart attacks were fatal (0.024 ‰). Patients operated under spinal anesthesia and patients aged 60 years and older had more adverse events with 20% and 10.38% for p <0.05 respectively. Sixty eight failures (5.4%) were observed. CONCLUSION: The practice of LRA at the University Hospital of Point G is characterized by adverse events and a low number of deaths. Patients operated under spinal anesthesia and patients aged 60 years and older are at greatest risk of adverse events.

OBJECTIF: Etait de faire le point de la pratique de l'ALR au Centre Hospitalier Universitaire (CHU) du Point G, de janvier 2004 à décembre 2008. MATERIELS ET METHODE: Il s'agissait d'une étude retrospective, évaluant la pratique de l'ALR. Les données démographiques, l'acte chirurgical, les caractéristiques techniques du geste effectué, le type d'anesthésique local utilisé, les événements indésirables ont été évalués. RESULTATS: L'ALR avait concerné 1.261 patients, soit 8,30%. La classification de l'American Society of Anesthesiology (ASA) était utilisée pour l'évaluation des patients en chirurgie programmé. Les patients étaient de la classe ASA1 (50,40%) et de la classe ASA2 (49,60%). Les principaux actes chirurgicaux étaient: l'adénomectomie 26,20%, la césarienne 23,80% et la fistulorraphie 19,04%. Les techniques d'ALR réalisées étaient: la rachianesthésie, 87,60%, l'anesthésie péridurale, 12%. Trois cents trois événements indésirables soit 24% ont été rapportés, dont trois soit 1% ont entrainé le décès du patient. L'incidence de l'hypotension artérielle a été de 94,40%, la bradycardie de 4,6%. Les trois arrêts cardiaques ont été fatals (0,024‰). Les patients opérés sous rachianesthésie et les patients âgés de 60 ans et plus avaient présenté plus d'événements indésirables avec respectivement 20% et 10,38% pour un p < 0,05. Soixante huit échecs (soit 5,4%) avaient été constatés. CONCLUSION: La pratique de l'ALR au CHU du Point G est caractérisée par des événements indésirables et un nombre de décès faible. Les patients opérés sous rachianesthésie et les patients âgés de 60 ans et plus sont les plus exposés aux événements indésirables.

Chemical and biological characterization of polysaccharides from wild and cultivated roots of Vernonia kotschyana.

ETHNOPHARMACOLOGICAL RELEVANCE: In Malian traditional medicine the roots of Vernonia kotschyana are used for treating gastric ulcer and gastritis. In 2006, 9000kg of roots from Vernonia kotschyana were used to produce Gastrosedal, an ameliorated traditional medicine in Mali. Harvesting from the wild, the main source of raw material, is causing a growing concern of diminishing populations of the plant, and Vernonia kotschyana is now being cultivated in several areas around Mali. In the current study the structures and bioactive properties of isolated polysaccharides from wild and cultivated Vernonia kotschyana were compared. MATERIALS AND METHODS: Pectin- and inulin-type polysaccharides were isolated from the roots of cultivated and wild Vernonia kotschyana. The isolated polysaccharides were investigated regarding their chemical compositions, and for their abilities to fixate human complement and activate macrophages from a mouse macrophage cell line. RESULTS: No significant differences in the carbohydrate composition of the fractions isolated from the cultivated versus the wild roots were observed. A previously reported pectic arabinogalactan Vk2a was found in both the cultivated and the wild roots in this study, and exhibited potent complement fixation activity, and a moderate activation of macrophages. CONCLUSIONS: The present study has shown that the cultivated roots of Vernonia kotschyana contain the same types of bioactive polysaccharides as the wild roots. It is therefore preliminarily feasible for the cultivated roots of Vernonia kotschyana to be used as a herbal medicine to replace the wild roots.

A metastatic case of gastrointestinal stromal tumor (GIST) treated with imatinib mesylate (Glivec(®)) in Mali.

Gastrointestinal stromal tumors (GIST) usually showing a spindle cells pattern of cell proliferation have recently benefit from a molecular definition. Indeed imatinib mesylate (Gleevec(®)) treatment has dramatically improved the management of these tumors as they frequently express the c-kit oncogene. We report the first case of a metastatic gastric GIST in a man of 45 years diagnosed and treated in Mali. The gastric tumor was particularly aggressive with a large intra-abdominal and mesenteric spreading and liver metastases. The diagnosis was done on the CD117 and CD34 expression in the tumor sample obtained by laparotomy. After a 34 months 400mg/day imatinib mesylate (Gleevec(®)) treatment a dramatic tumor regression was obtained.

[Frequency of red blood cell alloimmunization in polytransfused patients at the university teaching hospital of Point G, Bamako, Mali]. / Fréquence de l'allo-immunisation érythrocytaire chez les malades polytransfusés au centre hospitalo-universitaire du Point G, Bamako, Mali.

This prospective study conducted within 9 months period aimed to determine the frequency of red cell alloimmunization among polytransfused patients of the medical Hematology and oncology ward, and the unit of hemodialysis of the Nephrology ward at the Point-G hospital. Irregular red blood cell antibody screening and identification were performed by gel-filtration method using indirect antiglobulin test and enzymatic treated cells. We did not use saline medium. A total of 78 patients were included in this study. The mean age of the patients was 36.78±14.73 years (range: 11 and 77 years). The sex ratio was of 1.11 in favour of the women. The mean blood units transfused were 12.21±9.99 units (range: 4 and 45 units). The Rhesus phenotypes Dccee, DccEe and DCcee were most predominant, with the respective frequencies of 67.9, 15.4 and 10.3%. Kell antigen was found at a frequency of 1.28%. The total rate of red cell alloimmunization was 10.3%. There was no significant difference between the two wards. All the screened agglutinins were warm antibodies belonging to the Rhesus system: anti-E (7.7%), anti-C (1.3%) and anti-D (1.3%). Only Anti-E was present among hematologic patients. We did not find a significant link between the sex, the age, the number of blood units transfused and the positivity of the antibody screening. We conclude that the frequency of post-transfusional alloimmunization is high among polytransfused patients in Mali. A systematic antibody screening among these patients and the selection of red cells with known Rhesus/Kell phenotypes would allow an optimal blood transfusion safety.

[Cancer in Africa, a new health challenge. Examples of Mali and OncoMali]. / Le cancer en Afrique, un nouveau défi sanitaire. Exemples du Mali et de l'association OncoMali.

Oncology is perceived as a secondary problem of public health in emerging countries. Nevertheless the annual incidence of cancers is rapidly expanding (approximately 100 to 120/100 000 subsaharan Africa). It can explain by the high incidence of the infectious pathologies associated with a high oncogene risk (hepatitis, HIV, Helicobacter ...) but also by national and international prevention policies still too much reduced. If this epidemiological tendency continues, Africa will count in 2020 near a million new cases of cancers every year. The incidence increases but the morbi-mortality is also very high in these countries. This observation exceeds the simple consequence of a defect of means. The sociocultural landscape and the mental representations of this disease are also in cause. We shall evoke in this article the situation of Africa by quoting the example of Mali. We shall conclude on the individual contributions which can be made through the example of the association "OncoMali".

[Lymphocytic meningitis in Bamako, Mali]. / Les Meningites Lymphocytaires a Bamako, Mali.

We conducted a prospective survey from January 2001 to March 2002. Our objective was to study etiologic, clinic, and prognostic aspect of lymphocytic meningitis in hospital of Point G to Bamako. We included 35 patients with 25 male (71. 4%) and 10 female (28. 6%), sex - ratio (M / F) equal 2. 5. The median age was of 35 ± 25.4 years (range, 16 - 66 years). HIV serology was positive 26 cases (83. 9%). Clinical presentations were different. We observed 15 cases of encephalitis, 12 cases of meningoencephalitis, 2 cases of meningitis and 6 cases of febrile syndrome. Mean duration of hospitalization was 32. 6 ± 68 days. Mean of lymphocyte was 85.3 ± 25.9% among leukocytes in cerebrospinal fluid of 31 patients. Analysis of cerebrospinal fluid (CSF) identified in 9 cases Cryptococcocus neoformans. In 16 cases etiology was determination based on indirect arguments. In 9 cases viral meningoencephalitis diagnosis was made by exodiagnosis. It concerned 2 cases of TB meningitis, 1 case of cerebral toxoplasmosis, 1 case of decapitate bacterial meningitis and 1 case of cerebral tumor. Malaria thick smear permits to diagnosticate 1 case of cerebral malaria and 1 case of uncomplicated malaria. There are still 10 cases in which the cause remained unknown during study. HIV infection provides principally lymphocytic meningitis. Co morbidity with HIV is associated to lethality at 75%. But no statistical difference with patients without HIV (p = 0.52). Our work puts in exergue all problematic and hold correct of lymphocytic meningitis in our country.

[Epidemiology and morphology of breast benign tumors in Mali: about 186 cases]. / Epidemiologie et morphologie des tumeurs benignes du sein au Mali: a propos de 186 cas.

BACKGROUND: Mammary tumors are frequent. Benign tumors are more frequent, and are characterized by a possibility of recurrence or malignant transformation. The aim of this study was to describe the epidemiological and morphological characteristics of breast benign tumors. METHODS: The authors have undertaken a retrospective study from January 1998 to December 2003. This study was led in the laboratory of pathology of the National Institute of Public Health, in surgical and gynecological services of Bamako. The study had concerned all benign tumors confirmed by histology. FINDINGS: In total, 186 benign tumors were diagnosed over 611 mammary pathologies (30.44%). The average age was 27.1 +/- 11.7 years. Sex ratio was 17.6 in favour of women. The main complaint was feeling a nodule in the breast (91.9%). The most affected breast was the right side (50.8%). Tumor sizes were variable, and the color changed through white to yellow. Histological aspects were: fibroadenoma (72%), lipoma (8.6%), tubular adenoma (5.9%), papilloma (5.4%), lactating adenoma (3.8%), phyllodes tumor (3.8%), and syringomatous tumor (0.5%). CONCLUSION: Benign tumors are frequent in mammary pathology. The patients need a follow-up because of the recurrence or the malignant transformation of these tumors.
