Abstract
Tuberculosis disease stands for the second leading cause of death worldwide after COVID-19, most active tuberculosis cases result from the reactivation of latent TB infection through impairment of immune response. Several factors are known to sustain that process. Schistosoma mansoni, a parasite of the helminth genus that possesses switching power from an immune profile type Th1 to Th2 that favors reactivation of latent TB bacteria. The aim of the study was to assess the prevalence of the co-infection between the two endemic infections. Systematic literature was contacted at the University Clinical Research Center at the University of Sciences, Techniques, and Technologies of Bamako in Mali. Original articles were included, and full texts were reviewed to assess the prevalence and better understand the immunological changes that occur during the co-infection. In total, 3530 original articles were retrieved through database search, 53 were included in the qualitative analysis, and data from 10 were included in the meta-analysis. Prevalence of the co-infection ranged from 4% to 34% in the literature. Most of the articles reported that immunity against infection with helminth parasite and more specifically Schistosoma mansoni infection enhances latent TB reactivation through Th1/Th2. In sum, the impact of Schistosoma mansoni co-infection with Mycobacterium tuberculosis is under-investigated. Understanding the role of this endemic tropical parasite as a contributing factor to TB epidemiology and burden could help integrate its elimination as one of the strategies to achieve the END-TB objectives by the year 2035.

Abstract
INTRODUCTION The pure digestive form of COVID-19 is possible and initially considered rare. Our objectives were to determine the frequency of COVID-19 in patients treated in general surgery, identify the circumstances of COVID-19 discoveries in surgery, describe the post-operative complications in patients operated on COVID-1919 and describe the reorganization of post-operative COVID-19 diagnosis management. MATERIALS AND METHODS We conducted a prospective descriptive study from March 2020 to August 2021 (18 months). All patients who have been operated on, hospitalized or consulted in the department, the Emergency Department (ERS) or other CHU-GT departments for surgical pathology with COVID-19 or infected with COVID-19 while hospitalized were included in the study. RESULTS 23 cases collected, representing 8.91% (23/258) of COVID-19 cases identified, a frequency of 1.27/month. The age group 66-75 was the most affected, the average age was 49.13 18.75 years, the predominance was male (sex ratio of 1.3). More than 34.78% were recruited at the SAU, 16 patients (69.56%) consulted in emergency, and digestive signs of COVID-19 were: Abdominal pain 20 cases (89.96%), anorexia 19 cases (82.61%), vomiting 8 cases (34.78%) and diarrhea 3 cases (13.04%). The pulmonary signs of COVID-19 were: Cough 18 cases (78.26%), chest pain 15 cases (65.22%), and dyspnea 9 cases (39.13%). Manifestations of COVID-19 were: pulmonary 9 cases, digestive 9 cases, associated 3 cases, incidental discovery 2 cases. The diagnostic mean was Thoracic CT (100%), Test-PCR 14 cases (60.86%) with a positive PCR test in 50% of cases. Surgical pathologies were surgical emergencies in 7 cases (30.43%), cancers in 6 cases (26.09%), COVID-19 digestive event (30.43%) and other 3 cases (13.04%). More than half of patients were operated on 12 cases (52.17%). The overall mortality was 60.87% and the mortality of surgical patients was 41.67%. CONCLUSION The infectious risk of COVID-19 during hospitalization, during or after digestive surgery is a real and potentially serious risk for the patient and caregivers.

Abstract
COVID-19 was declared a pandemic in March 2020. For case management, Mali has created several treatment sites including the site of the CHU Gabriel Touré. AIMS The objective of the study was to analyse drug prescriptions for the COVID-19 treatment at the CHU Gabriel Touré. METHODS We performed a retrospective and descriptive study from April to September 2020. Drug prescriptions and hospital records were used to collect data. Prescriptions and hospital records were used to collect data. RESULTS A total of 29 patients were hospitalized. The median age was 44 years, 75.90% of patients had at least one pathology associated with COVID-19. The number of prescriptions was 333 comprising 870 lines of prescriptions including 33.21% for standard treatments, and 66.79% for associated pathologies. with 86.23% available at the Hospital Pharmacy. Chloroquine, dosed at 250mg, was administered at 500mg twice a day. The national guidelines from the treatment of COVID-19 recommends 200mg of chloroquine in two doses. Vitamin C was prescribed for all patients although not included in the national guidelines. The class of drugs for the blood and blood-forming organs was the most prescribed (31.49%). The average cost of treatments was 65,602 ± 106,858 FCFA with a maximum of 567,860 FCFA. An evaluation of prescriptions in other treatment sites is necessary.

Abstract
INTRODUCTION The use of blotting paper as a support for quantification of viral load could improve the virological monitoring of patients on Human Immunodeficiency Virus treatment in Mali. The urgency is obvious to us that the coverage in charge is only 10% for the achievement of the 3rd 90. OBJECTIVE To assess the performance of viral load screening (sensitivity, specificity, concordance) of DBS from the one spot DBS protocol according to plasma in people living with the human immunodeficiency virus (PLHIV) in Bamako. METHODS A total of 130 blotting papers were made from blood samples received from five sites for monitoring live persons with HIV. These blotting papers thus made were analyzed with the Abbott m2000 apparatus for the purpose of quantifying the viral load with plasma as reference sample. The extraction was done with the m2000SP automatic extractor, following the protocol 1.0 mL HIV-RNA DBS Protocol for paper. Furthermore, the extraction of plasma RNA on the m2000SP was done according to the 0.6 mL HIV-1 RNA protocol. RESULTS With 130 samples with detectable viral loads, we obtained a correlation of r = 0.837 (p <0.001). In addition, the average difference between the viral load on blotting paper and plasma was 0.512 log / virological copies with a kappa coefficient = 0.708. The threshold of 1000 copies / mL defined as virological success in our study allowed us to obtain a sensitivity of 87% and a specificity of 100%. CONCLUSION Decentralized zones or virological plasma monitoring is not accessible, the new Protocol one spot of Abbott laboratory offers an interesting opportunity for the follow-up of these patients with good performance at the threshold of 1000 copies. The use of DBS as a virological support can contribute effectively to the achievement of the 3rd 90.

Abstract
INTRODUCTION High blood pressure is a major cardiovascular risk factor. Patients with cardiovascular risk factors are at risk of developing COVID-19. The objective of this study was to determine epidemiology of Covid-19 infected in patients with high blood pressure. PATIENTS AND METHOD Descriptive cross-sectional study from April 2020 to June 2020 about patients hospitalized for Covid 19 by PCR diagnosis at the Hopital du Mali Bamako and having high blood pressure. Admission registry and patient charts were used to collect data. RESULTS We collected 78 out of 484 in patients which mean hospital frequency of 16.11%. The mean age was 55.21 +/- 14.61 years. Sex ratio M / F was 1.36. Patients were followed for high blood pressure in 59% of cases. Medical history was ischemic heart disease in 2.6% and dilated cardiomyopathy in 2.6%. Main functional signs were cough in 41.02% and lost of taste in 11.53%. High blood pressure on admission was grade 2 in 37.2% and grade 3 in 3.8%. Treatments received were calcium channel blockers 41.02%, inhibitors of the reninangiotensinaldosterone system 16.66% and combinations 15.38%. Hospital mortality was 10.3%. There was no statistically significant difference in mortality between known hypertensive patients and de novo hypertensive patients. There was also no statistically significant difference in mortality by grade of hypertension. CONCLUSION High blood pressure can be associated to Covid 19. Treatment is based on calcium channel blockers and reninangiotensinaldosterone system inhibitors. It has an impact on the prognosis of the disease with significant mortality.

Abstract
Cyst scar post circumcision of the stump of the prepuce is pathology of which we have not found any cases in the literature. The circumcision traditional is still practiced in our regions with its attendant complications, in particular, the high section, the whole or part of the gland, infections. The case we report concerns a patient 24 years of age, having a large cyst of 8cm diameter, evolving for the past 17 years. The patient has not informed his parents that when the desire to marry has become very pressing. The consultation was motivated by the psychological trauma, the discomfort and the pain caused by the infection, and the fistulisation. The treatment was surgical with bedroom suites. This observation underscores the importance of the knowledge of good surgical technique in order to minimize complications; it also sheds light on the taboo side of the pathologies the sphere uro-genitale.

Abstract
OBJECTIVES Our objective was to determine the frequency of bilio-digestive bypass in palliative surgery in pancreatic head cancers, to determine the clinical and para-clinical aspects and to analyze the results of the treatment. METHODS This was a-15 year retrospective study from 1999 to 2014 including any patient with confirmed pancreatic cancer in the anatomo-pathology treated by palliative surgery in the department. RESULTS In 15 years, we operated152 cases of cancer of the head of the pancreas. The bilio-digestive derivation was performed in 78 patients, or 51.32%. The average age was 58.61 years ± 11.22 years with the extremes of 34 and 79 years old, the sex ratio was 1.44. The disease duration was 4.88 months on average with a standard deviation of 4.28 months and extremes of 1 and 24 months. Courvoisier-Terrier's disease was observed in 76 cases with lesions of the cases. The average pancreatic tumor size was 62.98 mm, and standard deviation = 8.68 with the extremes of45 and 121 mm. We performed a choledoco-duodenal anastomosis and a gastro-entero-anastomosis (GEA) in 85.90% of cases (n = 67), a choledocojejunal anastomosis and a GEA in 7 cases and a choledoco-duodenal anastomosis without GEA in 4 cases. The morbidity and the mortality rates were15.4% and 6.41%, respectively. At six (6) months postsurgery, a complete disappearance the majority of the functional signs was observed. CONCLUSION Pancreatic cancer is a slowly developing tumor. Therefore its diagnosis is late; the derivation makes it possible to improve the quality of life of the patients.

Abstract
The aim of our study was to investigate the quality of information about pharmaceutical products in Mali. The study surveyed 98 prescribers, 60 pharmacists, and the package inserts of a basket of 30 generic medicines, compared to those of the corresponding proprietary versions. We made a rational choice of 98 doctors from various specialties and levels of the health system and randomly selected 60 of the 215 pharmacies in the district of Bamako (Mali). A rational sampling of generic medicines provided us with a basket of 30 drug notices for the antimalarial, antibiotic, antalgic, antipyretic, and anti-inflammatory agents used most in the Republic of Mali. This study showed that the pharmaceutical industry, through its sales representatives, are the main sources of drug information and that this information is not always adequate. The study also found that the content provided with generic medicines is sometimes different from the information for the proprietary brand-name drugs.

Abstract
BACKGROUND In 2002, following establishment of a clinical microbiology laboratory in the government hospital that admits children with severe illnesses in Bamako, Mali, surveillance to identify pathogens causing invasive bacterial infections (septicemia, bacteremia, meningitis, etc) was initiated. METHODS Parents/guardians of children aged <16 years admitted to l'Hôpital Gabriel Touré with high fever or clinical syndromes compatible with focal invasive bacterial disease were asked for consent to culture their child's blood/body fluid. Standard bacteriologic techniques speciated isolates; Salmonella serovars were determined. RESULTS From July 2002 through June 2014, 687 nontyphoidal Salmonella (NTS) isolates were obtained from 667 children; 667 yielded a single serovar and 20 grew 2 Salmonella serovars, 1 being NTS. Four serovars accounted for 87% of the 687 NTS isolates, including Salmonella Enteritidis (n = 244 [35.5%]), Salmonella Typhimurium (n = 221 [32.2%]), I:4,[5],12:i:- (n = 42 [6.1%]), and Salmonella Dublin (n = 89 [13.0%]). Of 553 patients with invasive NTS from whom 1 of the 4 predominant serovars was isolated in pure culture, 448 (81.0%) were aged <5 years and case fatality was 20.3%; Salmonella Enteritidis case fatality (27.8%) was higher than for other serovars (P = .0009). NTS disease showed a seasonal peak following the rainy season and into the cool, dry season. Since 2010, Salmonella Enteritidis cases have risen and Salmonella Typhimurium fallen. CONCLUSIONS NTS has become the predominant invasive pathogen as Haemophilus influenzae type b and pneumococcal vaccine use in Mali has diminished invasive disease due to those pathogens. The age distribution and limited serovars involved make control of NTS disease by vaccines epidemiologically feasible, if products under development prove safe and efficacious.

Abstract
Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae have been isolated from many regions of the world. Epidemiological studies are being conducted in Europe, North America, and Asia. No study has however been conducted in Africa to determine the prevalence and distribution of ESBLs on the continent. This literature review aimed at describing the prevalence of ESBL-producing Enterobacteriaceae isolated from blood cultures, as well as the ESBL genes involved at the international level. Our focus was mainly on Africa. We conducted a literature review on PubMed. Articles related to our study field and published between 1996 and 2014 were reviewed and entirely read for most of them, while we only focused on the abstracts of some other articles. Relevant articles to our study were then carefully reviewed and included in the review. The prevalence of ESBL-producing Enterobacteriaceae differs from one country to another. The results of our literature review however indicate that class A ESBLs prevail over the other types. We took into consideration articles focusing on various types of samples to assess the prevalence of ESBL-producing Enterobacteriaceae, but information on isolates from blood cultures is limited. The worldwide prevalence of ESBL-producing Enterobacteriaceae has increased over time. Evidence of ESBL-producing Enterobacteriaceae can be found in all regions of the world. Studies conducted in Africa mainly focused on the Northern and Eastern parts of the continent, while only rare studies were carried out in the rest of the continent.

Abstract
BACKGROUND AND PURPOSE ρ-Da1a, a 65 amino-acid peptide, has subnanomolar affinity and high selectivity for the human α(1) (A) -adrenoceptor subtype. The purpose of this study was to characterize the pharmacological effects of ρ-Da1a on prostatic function, both in vivo and in vitro. EXPERIMENTAL APPROACH ρ-Da1a was tested as an antagonist of adrenaline-induced effects on COS cells transfected with the human α(1) (A) -adrenoceptor as well as on human isolated prostatic adenoma obtained from patients suffering from benign prostatic hyperplasia. Moreover, we compared the effects of ρ-Da1a and tamsulosin on phenylephrine (PHE)-induced increases in intra-urethral (IUP) and arterial pressures (AP) in anaesthetized rats, following i.v. or p.o. administration. KEY RESULTS On COS cells expressing human α(1) (A) -adrenoceptors and on human prostatic strips, ρ-Da1a inhibited adrenaline- and noradrenaline-induced effects. In anaesthetized rats, ρ-Da1a and tamsulosin administered i.v. 30 min before PHE significantly antagonized the effects of PHE on IUP. The pK(B) values for tamsulosin and ρ-Da1a for this effect were similar. With regards to AP, ρ-Da1a only reduced the effect of PHE on AP at the lowest dose tested (10 μg·kg(-1) ), whereas tamsulosin significantly reduced PHE effects at doses between 10 and 150 μg·kg(-1) . CONCLUSIONS AND IMPLICATIONS ρ-Da1a exhibited a relevant effect on IUP and a small effect on AP. In contrast, tamsulosin antagonized the effects of PHE on both IUP and AP. We conclude that ρ-Da1a is more uroselective than tamsulosin. ρ-Da1a is the most selective peptidic antagonist for α(1A) -adenoceptors identified to date and could be a new treatment for various urological diseases.

We conducted a prospective study, lasting 16 months, from January 2005 to April 2006, looking at 40 cases of generalized acute peritonitis operated in several services, including a general surgery department, of the Sominé Dolo's hospital of Mopti. RESULTS We noted a hospital admittance rate of 3.1% with an average age of 26.3 years old and a 1.66 men to women ratio. Peritonitis at the Sominé Dolo hospital was dominated by intestinal perforation. The diagnosis was essentially made using the clinical approach. The treatment was medico-surgical. Operative mortality was recorded in 7 cases (17.5%) with 7 cases of inner-wall abscesses. The delay of consultations and the Mannheim score were the main factors causing bad prognostics. Excision - sutures associated with a cleansing drainage of the abdominal cavity was the most practised surgical procedure. CONCLUSION Mortality remains high. The two factors for a bad prognostic are the delay of consultation and the lack of means for reanimation.

Abstract
UNLABELLED The objectives were to determine the frequency, to describe the clinical, therapeutic aspects and to evaluate the cost of the assumption of responsibility of occlusions by supports and or adherences. It was about a retrospective study carried out in the department of surgery general of the CHU Hôpital Gabriel TOURE from January 1st, 2002 to December 2008. Were included in this study all the patients operated for occlusion of hail on Brides and Adherence confirmed in per operational. We colligé 659 acute obstructions of the bowels whose 100 occlusions of hail on supports and adherences is a frequency of 17,8%. They were 55 men (55%) and 45 women (45%). The sex-ratio was of 1,2. The average age was 39,7 years with the extremes varying between 15ans and 80 years. Eighty eight of our patients had surgical antecedents including 14 (16%) of surgery known méso colic and 74 (84%) of surgery under méso colic. Twelve patients had antecedents of contusion and untreated abdominal infections. Among the signs of the occlusive syndrome, the abdominal pain was found at all the malades100 (100%), the vomiting (98), the stop of the matters (88) and the gases (80). The ASP was carried out at 98 of our patients and 74 (75,5%) presented radiological images in favor of the occlusion of hail. The leading cause of occlusion was the supports (67), the supports and adherences (18) and adherences (15). The small intestine was hyperhémié chez14 patient, was necrosed among 16 patients and normal in the 70 cases. The surgical treatment consisted with a section of the support among 60 patients Adhésiolyse among 15 patients, a Adhésiolyse section among 10 patients, a résection Iléostomie among 10 patients and a résection - immediate anastomosis among 5 patients. The rate of morbidity was of 28%, it related to the infection of the operational site 18cas, the digestive dent 6cas and the eventration 4cas. Mortality was of 8%. Intermediate duration of hospitalization 14,8 days. The average costs of the assumption of responsibility were of 156.900 francs CFA. CONCLUSION Mortality and postoperative morbidity are not negligible. Gravity of this pathology underlines the interest of it's fast assumption.

Abstract
INTRODUCTION the omphalocèle is an evolution of the extra embryonic coulombs between the 32th and the 72th days of the pregnancy. The treatment depends on his volume. In Mali; few works were published on the omphalocèle and its treatment. MATERIALS AND METHOD we brought together 111 cases of omphalocèles during 8 years of study with the aim of determining the epidemiological factors and describing the clinical and therapeutic aspects. RESULTS 49 patients on 111 were of the male and aged between 4,2 days with weight between 2500 - 3500 g. The diameter of the r snare was superior to 8 cms in 29(26,13%) cases and has benefited a conservative treatment according to Grobb. 13 patients had a rupture of the membrane. The liver has been found in 29 time (26,13%) in the sac and 35 case and associated malformation. 20 cases of death have been observed. Antenatal ultrasound found exomphalos in 9 cases. Any mother had a story of teratogenic medications and 67 mothers were multipared. CONCLUSION Omphaloceles are multidiscipli-nary surgical emergencies. Antenatal echogra-phy is useful for the antenatal diagnosis.

Abstract
INTRODUCTION The incisional hernia is a frequent complication of the opened abdominal surgery. The objectives of this study were to determine the hospital frequency and the favoritizing factors, to analyze the therapeutic aspects. MATERIALS AND METHODS We realized a retrospective study from January, 1999 to December, 2005 in the services of general and paediatric surgery of teaching hospital Gabriel Touré. It concerned 45 cases of incisional hernia. The hernias of the abdominal wall, the abdominal and traumatic hernia were not retained. RESULTS The frequency was 0.52%; the average age of our patients was 37.8 years with a sex ratio of 2 in favour of the woman. The average delay of consultation was of 59 months with extremes going from 2 to 11 months. Favoritizing factors found were the parietal suppuration to 13 (28.8%) patients and the multiple interventions to 8 (17.8%) patients. The average dimension of the hernia was 9.5 cms ± 3.8 with extremes going from 5 to 14 cms. The 45 patients benefited from the cure of the hernia according to Mayo. We didn't lost any patient. 2 parietal suppurations happened post-operatively. CONCLUSION Incisional hernia treatment consists for Mayo's method or prosthesis. The laparoscopic surgery can reduce complications.

Abstract
AIM The study aims to describe cardiovascular risk factor according to gender in hospital. MATERIAL AND METHODS Il was a prospective study from april 2007 to march 2008 including 146 highblood pressure patients from 2 medical centre in Bamako. Gathering and analysis were performed with SPSS 11. RESULTS 67% were female, the mean age reached 48,82. the BMI was significantly higher in female (P <0,001). Female were mainly registered between 30 and 44 years, and male between 45-59 years. Overweight and obesity were more represented in female and obesity in 30-44 years old patients. Isolated highblood pressure was found in 58,90%, 7,53% of patients had the 3 major cardiovascular risk factor CONCLUSION Isolated highblood pressure was by far the most frequent. Although the cardiovascular risk rises with the others associations, they were rare and don't significantly differ in each gender. The tendency to overweight and obesity in female should be confirmed by others studies.

Abstract
BACKGROUND AND PURPOSE Venoms are a rich source of ligands for ion channels, but very little is known about their capacity to modulate G-protein coupled receptor (GPCR) activity. We developed a strategy to identify novel toxins targeting GPCRs. EXPERIMENTAL APPROACH We studied the interactions of mamba venom fractions with alpha(1)-adrenoceptors in binding experiments with (3)H-prazosin. The active peptide (AdTx1) was sequenced by Edman degradation and mass spectrometry fragmentation. Its synthetic homologue was pharmacologically characterized by binding experiments using cloned receptors and by functional experiments on rabbit isolated prostatic smooth muscle. KEY RESULTS AdTx1, a 65 amino-acid peptide stabilized by four disulphide bridges, belongs to the three-finger-fold peptide family. It has subnanomolar affinity (K(i)= 0.35 nM) and high specificity for the human alpha(1A)-adrenoceptor subtype. We showed high selectivity and affinity (K(d)= 0.6 nM) of radio-labelled AdTx1 in direct binding experiments and revealed a slow association constant (k(on)= 6 x 10(6).M(-1).min(-1)) with an unusually stable alpha(1A)-adrenoceptor/AdTx1 complex (t(1/2diss)= 3.6 h). AdTx1 displayed potent insurmountable antagonism of phenylephrine's actions in vitro (rabbit isolated prostatic muscle) at concentrations of 10 to 100 nM. CONCLUSIONS AND IMPLICATIONS AdTx1 is the most specific and selective peptide inhibitor for the alpha(1A)-adrenoceptor identified to date. It displays insurmountable antagonism, acting as a potent relaxant of smooth muscle. Its peptidic nature can be exploited to develop new tools, as a radio-labelled-AdTx1 or a fluoro-labelled-AdTx1. Identification of AdTx1 thus offers new perspectives for developing new drugs for treating benign prostatic hyperplasia.

Abstract
OBJECTIVES In resource-limited countries, HIV-1 RNA quantification is usually performed in reference laboratories. Samples from remote areas are transported under suboptimal conditions. Here we evaluated HIV-1 RNA stability in plasma stored at different temperatures for 1 week. METHODS Blood samples collected in ethylenediaminetetraacetic acid (EDTA) and processed within 6 h of collection were tested by HIV-1 RNA quantification using Roche Cobas Ampliprep-Cobas TaqMan (Roche Diagnostics). The results were compared with matched HIV-1 RNA concentrations determined from plasma stored for 1 week at 4, 22, 30 or 37 degrees C. RESULTS A total of 51 samples were evaluated: 10 stored at 4 degrees C, 15 at 22 degrees C, 16 at 30 degrees C and 10 at 37 degrees C. Keeping plasma at 4, 22 or 30 degrees C for 1 week did not affect HIV RNA measurement. Compared with HIV-1 RNA concentrations determined from fresh plasma, the correlation was significant for each of the three temperatures with no RNA decay. In contrast, HIV-1 RNA levels decreased significantly when plasma was stored at 37 degrees C. The 10 samples submitted at this temperature showed a weaker correlation (rho=0.84; P=0.012) and a significantly reduced median HIV-1 RNA concentration (-0.92 log(10) HIV-1 RNA copies/mL; P=0.005). CONCLUSION Plasma can be saved for up to 1 week at 30 degrees C before shipping to a reference laboratory for HIV-1 RNA quantification.

Abstract
This study evaluated the attitudes and practices of the personnel with respect to the prevention of nosocomial infections in a hospital environment. We carried out a qualitative survey of all categories of personnel between July 1998 and March 1999, at the five regional hospitals in Senegal (Thiés, Kaolack, Saint-Louis, Diourbel, and Louga). Data were collected in two ways: using a questionnaire to evaluate knowledge and by observing the attitudes and practices of the personnel. Hands were rarely washed before and after each procedure and surgical washing was often performed in poor conditions. The decontamination of soiled equipment was ineffective. Reusable instruments were washed directly with bare hands or by individuals wearing used surgical gloves. The equipment used for sterilization was dilapidated and unsuitable and the norms for sterilization were seldom respected. Circulation in the region of the operating theatre was disorganized, if not anarchic. The personnel had a high risk of contamination from blood. Biomedical waste was not decontaminated: it was collected poorly and disposed of directly into the environment. None of the sites visited had a program of waste incineration. In conclusion, at the sites visited, there is a high risk of nosocomial contamination during care and the reuse of equipment, for both the staff and the patients treated.

Abstract
According to data sent to Bamako in March 1998 for the annual review of National Programs for the Eradication of the Guinea Worm (NPEGV), dracunculiasis was observed in 211 villages in Burkina Faso in 1997. Of this total, 110 (52 p. 100) were new villages not previously reporting dracunculiasis. A study focusing on these new villages was carried out in June 1998. The aim of the study was to evaluate the quality of the disease monitoring system and determine if endemicity was spreading to new villages. A twofold method was used first to analyze the data used in the geographic information section of the disease monitoring system and second to test the validity of this data in field surveys. Findings showed the actual number of new villages showing endemicity could be reduced from 46 p. 100 to 12 p. 100 since 67 p. 100 of the new villages had in fact previously reported endemicity but had been wrongly eliminated from monitoring records. This probably long-standing problem has been uncovered with a decrease in the number of villages showing endemicity and an increase in prevention activities. In addition this study identified several confounding factors and defects in disease monitoring and data reporting techniques. Based on this study, several recommendations were made to improve the quality of the disease monitoring system.

Abstract
During the 1993 rainy season, 15,806 mosquitoes, including 14,304 Aedes ssp., were collected and tested for virus infection in 702 and 547 pools, respectively. Aedes furcifer (Edwards) was the most abundant species collected throughout the survey period. Yellow fever (YF) virus was detected in 187 pools: Ae. furcifer (123 isolates), Ae. taylori (Edwards) (41 isolates), and Ae. luteocephalus (Newstead) (23 isolates). A high prevalence of immunoglobulin (IgG) antibodies was found in human and simian populations. Results clearly indicated that increased sylvatic YF activity in eastern Senegal has the increased the risk of YF transmission among rural populations in West Africa. Our results showed that a minimal survey period may be effective in detecting the circulation of YF in the Kedougou area.

Abstract
The authors draw up "paludometric indications" by studying 938 children and youths, in the Kadiolo area, a humid savanna in the south of Mali, by the end of the dry season (beginning of March). These results give a global indication of 70.6% (cases of malaria) with 94.4% of P. falciparum and 9.96% cases of gametocytic indications. The numbers obtained far from the rainy season let us think that the annual transmission of malaria is continuous with a recrudescence in the humid season explaining largely the infantile mortality. The use of Nivaquine may easily protect these populations from the risk of malaria disease.
