Etude de la dynamique des populations d’Anopheles gambiae s.l et polymorphisme allélique du gène TEP1 en période de transmission du paludisme dans la commune rurale de Bancoumana, Mali. La lutte anti vectorielle est une stratégie importante de lutte contre le paludisme, elle permet l’interruption dans la chaîne de transmission du paludisme. Cette lutte inclut la connaissance approfondie du vecteur et les facteurs environnementaux qui ont une influence sur sa vie. L’objectif de cette étude est d’étudier la dynamique de la population adulte d’An.gambiae s.l. et d’évaluer le polymorphisme allélique du gène TEP1 impliqué dans la lyse parasitaire chez le vecteur. Cette étude était conduite dans une zone d’endémie palustre à Nanguilabougou et son hameau de culture Kouroubabougou dans la commune rurale de Bancoumana entre Juin 2014 et Novembre 2015 durant la saison de transmission du paludisme. Les moustiques étaient collectés à l’aide de pièges lumineux, conservés dans des tubes de 50 ml contenant de l’éthanol à 70%, ont été traités au laboratoire avec la PCR (extraction de l’ADN, identification des espèces et génotypage). En 2014 parmi les 1433 moustiques collectés, l’espèce An. coluzzii était prédominante 72,2%, suivi d’An. gambiae 21,1% et l’hybride An. coluzzi/gambiae 3,1%. La même situation était observée en 2015 sur 6612 moustiques collectés, An. coluzzii 72,4%, An. gambiae 16,7% et l’hybride 0,4%. Deux An. arabiensis ont été trouvés en 2015. Une forte présence du génotype R1/R1 chez l’espèce An. coluzzii 85,2% en 2014 et 66,2% en 2015 a été constatée. L’espèce An. gambiae était plus associée au génotype S1/S1 en 2014 et S1/R2 en 2015. Les autres formes alléliques étaient faiblement présentes.An. coluzzi était prédominante parmi les espèces d’An. gambiae s.l. Elle avait une fréquence élevée du gène TEP1 impliqué dans la lyse parasitaire chez les moustiques.

Aims: The goal of our work was to clarify the epidemiologicals, clinicals, etiologicals and prognostics of upper gastrointestinal bleeding at Segou Regional Hospital. Patients and methods: This cross-sectional study, which took place from October 1, 2017 to September 31, 2018, involved patients hospitalized for digestive hemorrhage. Results: Upper gastrointestinal bleeding represented 9.7% of all hospitalizations. The mean age of the patients was 50, 94 ± 21, 6 years with a sex ratio of 1.6 in favor of men. Housewives and farmers were represented in 37.7% and 34% of cases. The main modes of disclosure were hematemesis and melena. Evolution was favorable with a mortality of around 34%. Conclusion: upper gastrointestinal bleeding is relatively common in our context. High mortality is linked to delayed treatment. [ABSTRACT FROM AUTHOR]

The normal resistance and the tangential conductivity of a single fracture with Gaussian or self-affine surfaces are systematically studied as functions of the nature of the materials in contact and of the geometrical parameters. Analytical formulas are provided in the lubrication limit for fractures with sinusoidal apertures; these formulas are used to substantiate empirical formulas for resistance and conductivity. Other approximations based on the combination of series and parallel formulas are tested. [ABSTRACT FROM AUTHOR]

Introduction: Bladder and ureteral lesions are the most common urologic complications occurring during pelvic surgery with 1% and 0.5% to 3%, respectively. These lesions are rarely recognized intraoperatively and pose a major problem to urologists, gynecologists, and general surgeons. Objective: To study the factors favoring urologic complications following pelvic surgery at the University Hospital Point-G. Patients and Method: We conducted a retrospective study at the University Hospital Point-G between 2006 and 2015. It involved 23 patients with a whole urological lesion following pelvic surgery. These patients underwent a clinical and para-clinical examination (intravenous urography, methylene blue test) to confirm the urological lesion and to determine its management. Results: The average age of our patients was 32.00 years with extremes of 18 and 40 years old. The leakage of urine was found in 82.6% (19/23). Interventions that caused urologic injury were: caesarean section 52.2% (12/23), hysterectomy 30.4% (7/23), as well as a caesarean section and hysterectomy 17.4% (4/23). Methylene blue was performed in 19 patients, it was positive in 52.2% (12/23) and intravenous urography (IVU) in 7 patients. The lesions encountered were: retrotrigonal fistula vesico-vaginal 10 cases, vesico-vaginal fistula under trigonal 2 cases, uretero-vaginal fistula 7 cases, and bilateral ureteral ligation 4 cases. Fistulorraphy was performed in 52.2% followed by direct ureterovesical reimplantation. The postoperative outcome was satisfactory in 100% of cases with obtaining a good bladder tightness. The average duration of hospitalization was 12 days (+/- 4 days). Conclusion: Pelvic surgery results in urological injuries. Caesarean section and hysterectomy are contributing factors. Vesico-vaginal fistula or ureteral lesions are common. [ABSTRACT FROM AUTHOR]

Introduction: The pulmonary hydatid disease has not been the subject of many studies in Mali.Objective: List the cases hydatid cyst of the lung operated on in Mali, in order to analyze their surgical aspects.Methods and patients: This is a retrospective study of consecutive and non-selected cases. From 1960 to 2000, eleven cases of the pulmonary hydatid disease were operated on in Mali. The earliest case dates back to 1968 and the most recent was in 2000. All of these patients were taken care of at the ‹ Point G Hospital › in Bamako.Results: Patients were aged between 4 and 42 years, with an estimated average at 20. The gender ratio (F/M) was 1.75. The circumstance leading to the discovery stems from 8 cases of cough. Seven patients had at least a sign of complicated cyst. Out of a total of 12 cysts, 9 were located to the right lung. The treatment of the cyst consisted in a kystectomy accompanied by an atypical resection of the parenchyma on 6 patients and a typical resection of the attacked lobe on 5 others. The operating effects were complicated in 5 cases. No mortality was reported. Anatomopathology confirmed pulmonary hydatidosis in all cases.Conclusion: Paradoxically, the frequency of pulmonary hydatidosis is low in Mali. Patients were consulted late. This explains in part the high level of lobectomy during surgical treatment. [Copyright &y& Elsevier]

This study is aimed at the analysis of the pyrolysis kinetics of Nanche stone BSC ( Byrsonima crassifolia) as an agro-industrial waste using non-isothermal thermogravimetric experiments by determination of triplet kinetics; apparent activation energy, pre-exponential factor, and reaction model, as well as thermodynamic parameters to gather the required fundamental information for the design, construction, and operation of a pilot-scale reactor for the pyrolysis this lignocellulosic residue. Results indicate a biomass of low moisture and ash content and a high volatile matter content (≥70%), making BCS a potential candidate for obtaining various bioenergy products. Average apparent activation energies obtained from different methods (KAS, FWO and SK) were consistent in value (~123.8 kJ/mol). The pre-exponential factor from the Kissinger method ranged from 10 5 to 10 14 min -1 for the highest pyrolytic activity stage, indicating a high-temperature reactive system. The thermodynamic parameters revealed a small difference between E A and ∆H (5.2 kJ/mol), which favors the pyrolysis reaction and indicates the feasibility of the energetic process. According to the analysis of the reaction models (master plot method), the pyrolytic degradation was dominated by a decreasing reaction order as a function of the degree of conversion. Moreover, BCS has a relatively high calorific value (14.9 MJ/kg) and a relatively low average apparent activation energy (122.7 kJ/mol) from the Starink method, which makes this biomass very suitable to be exploited for value-added energy production.

This study focused on the analysis of the pyrolytic behavior of four lignocellulosic biomasses: avocado stone (AS), Agave salmiana bagasse (AB), cocoa shell (CS), and α-cellulose (CEL). According to the triplet kinetics analysis, the order of pyrolytic decomposition was AS < AB < CEL < CS. The AS was dominated by a second-order reaction, while AB followed a 2D diffusion-Valensi model. On the other hand, the pyrolysis of CS starts with an nth-order reaction and ends random nucleation model, and CEL was dominated by one-dimensional diffusion and first-order reaction. Thermodynamic studies reveal that the difference between the activation energy versus enthalpy change was<6.5 kJ/mol for all biomasses, thus showing the ease of pyrolysis reaction of these biomasses. Furthermore, the AS and AB showed that the reactions are close to thermodynamic equilibrium and stability, whereas CS and CEL indicated high reactivity., (Copyright © 2021 Elsevier Ltd.

Aim: To determine the frequency of the surgery wound infection, its favoring factors, causative germs and its antibiotic treatment of choice in the surgery "A" department of the University Hospital Point G., Method: In a retrospective descriptive study over a 6-month period in the surgery "A" department of the University Hospital Point G, we enrolled all patients who underwent surgery necessitating at least 48 hours of hospital admission during our study period and in conformity with the Atlanta CDC criteria. Surgery patients with less than 48 hours postoperative hospital stay and those admitted to the hospital without surgery were not included.After the surgery, the nature and location of the infection have been clarified. In this work, ethical considerations have been respected and there is no conflict of interest., Results: Two hundred and sixty-five (n=265) patient files were collected including 24 cases of surgery wound infection (a hospital frequency of 9%. The average age was 41.41 years (y.o) old with extremes of 7 y.o and 102 y.o. The sex ratio was 0.9 in favor of women. The commonly studied pathologies were digestive surgery in 52.8%, gynecological surgery in 24.5%, etc… Patients were seen in regular outpatient surgery visits in 75.8% and surgical emergencies in 24.2%. Of the patients urgently admitted, 26.5% presented an ISO; for those received in ordinary consultation it was 3.48%. Fifteen (15) cases were classified ASA III and two (2) ASA II. Based on the Altemeier classification, surgery was clean in 66.8% of our patients, contaminated clean in 12.4%, contaminated in 12.1%, and dirty in 8.7% (including half resulting in surgery wound infection). In total, 79% of patients whose surgeries lasted more than two (2) hours presented a surgery wound infection. Postoperative infection of patients was superficial in 58.3% and deep in 33.3%. In 8.3% of cases, it was a space infection. At the cytobacteriological examination of the pus from the operative site, Escherichia coli (E. coli) was the most common germ with 58.3%. E. coli was sensitive to amoxicillin-clavulanic acid in 57.14%. Surgically, a re-intervention was performed in 20.8% of cases, a secondary suture in 12.5%, and a single dressing in 66.7%. The average postoperative stay was 6.5 days with extremes of 2 days and 69 days. In 3 months postoperatively we recorded 4 cases of death., Conclusion: The surgery wound infection constitutes a major complication in a surgical environment starting with surgical act itself.Particular emphasis should be placed on prevention, which will reduce the risks of ISO occurrence., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

The aim of this study was to evaluate the surgical treatment of goiter in the «A» surgical department of the Point G University Hospital in Bamako., Patients and Methods: This was a retrospective and descriptive study in the «A» surgical department of the Point G University Hospital from January 2007 to August 2014. Included in the study were all the patients operated for goiter. The patients who underwent surgery for other thyroid diseases were not selected. Postoperatively patients were followed for one year. The sociodemographic, clinical, para-clinical, therapeutic aspects and the postoperative course were the study parameters. Data analysis was performed on SPSS 21. The Chi square test was used for statistical analysis. A p-value inferior to 0.05 was considered statistically significant., Results: A total of 378 patients' records were collected. Thyroidectomy represented 6.2% (378 cases) over 6027 operations. The mean age was 41.29 years with a standard deviation of 13.58. Extremes were 3 and 85 years. The sex ratio was 7.22 in favor of women. The frequent reason for consultation was due to antero-cervical tumor with 97.07% of cases (n = 367). We identified 118 cases (31.22%) of goiter in cooled hyperthyroidism patients, 211 cases (55.82%) of euthyroid goiter, 7 cases (1.85%) of the thyroid neoplasia and one case (0.3%) of hypothyroidism goiter. Pathological histology helped to highlight a micro-vesicular macro adenoma in 16.1% of cases (61 patients); adenocarcinoma in 0.7% of cases (3 patients) and papillary carcinoma in 1.1% of patients (4 patients). The patients classified as ASA I and ASA II represented the majority with respectively 248 cases (65.60%) and 120 cases (31.74%). The most performed surgical techniques were subtotal thyroidectomy (n=181; 49.7%), the isthmo-lobectomy (126; 33.3%), total thyroidectomy (n=11; 2.9%) and sternotomy in one case of endothoracic goiter. Intraoperative complications were marked by hemorrhage in 12.7% of cases (45 patients). The postoperative one month follow up was uneventful in 91.79% (n = 347) and transient recurrent nerve injury was found in 2% of cases (1 patient). In one year follow up the postoperative outcome was good in 94.17% (n = 356) of patients. The mean hospital stay was 4.18 days. Six deaths were recorded (1.7%)., Conclusion: Goiter surgery is relatively common in the surgery 'A' department of the Point G University hospital. Good patient preparation and a better postoperative monitoring could help to minimize postoperative complications., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Numerous studies have shown the influence of some bacteria colonizing the breeding sites on the development of the parasite in Anopheles malaria vectors. The aim of this study was to evaluate the impact of the breeding sites of Plasmodium falciparum on the gametocytes infectivity of Anopheles gambiae sl using the membrane feeding method. We carried out an experimental infestation study from September 2010 to January 2011 in a village located in the southern savanna of Mali. Cross sectional surveys were conducted to collect larvae and to select gametocyte carriers. Female offspring of L3 and L4 stage larvae were used for the experimental infestation. The gametocyte carriers were children aged within 4 to 12 years. Bacteria identified in breeding water of larvae and adult mosquitoes were: Escherichia coli, Salmonella spp, Klebsiella oxytoca, Pseudomonas spp, Staphylococcus spp, Shigella sp. The oocyst load of infected mosquitoes did not significantly vary according to the samples (F = 1.517, P = 0.230). Low infection rates (5.4% and 2.8%) were observed in the larval bedding and in mosquitoes containing K. oxytoca and Shigella. The blood feeding rates (62.4%; 60.9%; 67.7%) and mortality (66.4%; 64.9%; 61.9%) of An. gambiae did not significantly vary depending on the breeding sites [(P = 0.15); (P = 0.22)]., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

The aim of this study was to identify factors influencing the clinical outcomes of surgery of obstetric urogenital genital fistula. This was a cross sectional study, which focused on factors influencing results in the treatment of urogenital fistula, from January 2011 to January 2012 at the urology department of the Point-G University Hospital. This study involved 115 patients suffering from urogenital fistula. Cure of urogenital fistula accounted for 17% of the bloc's activities. Closure of the fistula was achieved in 68.7% of cases. This result was influenced by certain factors. Including factors related to condition of the tissue peri-fistula (good trophic tissue, or fibrosis peri-fistula). Fistulas operated primarily peri-sinus tissue remodeling were closed in 71.42% of cases. Factors related to the patient and care: those carried out for the first time have a success rate of 68.42%, only 47.62% of success in patients who presented after five years. Factors related to clinicopathological seat: fistula vesicovaginal septum and cervical-vaginal urethrovaginal reported a success rate of 76.92%. Care-related factors include: the experience of the surgeon, surgeons of the urology service have a 76.19% success rate against 25% from other surgeons. The incision fistula was related to the clinicopathological seat, so the trigonal-vaginal fistulas and uretero addressed by the upper route have been successful in 85%.
