Abstract
Burns are frequent lesions, often leading to serious functional or even life-threatening sequelae. Their care poses a problem in the countries of the South due to the lack of specialized centres. Through this study, we would like to share our experience. This was a descriptive retrospective study carried out over 36 months on 24 patients treated and followed up in the department for burn sequelae involving a limb. Functional results were classified as excellent, good, fairly good, fair and poor. Aesthetically, they have been categorized into satisfactory, unsatisfactory and poor. We recorded 1480 patients who underwent surgery, 24 of whom were operated on after burns. We noted a female predominance (sex ratio of 1.6) with an average age of 24.2 years (range 16-40). Domestic accidents (n=19) were the main circumstance of occurrence and there was a preponderance of thermal burns by flame (n=21). Twenty people were treated in the first year after burn with excellent, good and fair results in 10, 9 and 4 cases respectively. Burns can cause significant functional sequelae, the management of which requires specialized nursing staff. Training of caregivers oriented towards burn care without forgetting the related means remains a key element to minimizing the occurrence of these sequelae.

Abstract
Male infertility is common and complex, presenting a wide range of heterogeneous phenotypes. Although about 50% of cases are estimated to have a genetic component, the underlying cause often remains undetermined. Here, from whole-exome sequencing on samples from 168 infertile men with asthenoteratozoospermia due to severe sperm flagellum, we identified homozygous ZMYND12 variants in four unrelated patients. In sperm cells from these individuals, immunofluorescence revealed altered localization of DNAH1, DNALI1, WDR66, and TTC29. Axonemal localization of ZMYND12 ortholog TbTAX-1 was confirmed using the Trypanosoma brucei model. RNAi knock-down of TbTAX-1 dramatically affected flagellar motility, with a phenotype similar to the sperm from men bearing homozygous ZMYND12 variants. Co-immunoprecipitation and ultrastructure expansion microscopy in T. brucei revealed TbTAX-1 to form a complex with TTC29. Comparative proteomics with samples from Trypanosoma and Ttc29 KO mice identified a third member of this complex: DNAH1. The data presented revealed that ZMYND12 is part of the same axonemal complex as TTC29 and DNAH1, which is critical for flagellum function and assembly in humans, and Trypanosoma. ZMYND12 is thus a new asthenoteratozoospermia-associated gene, bi-allelic variants of which cause severe flagellum malformations and primary male infertility.

Abstract
RESEARCH QUESTION Do patients presenting with flagella ultrastructural defects as assessed by electron microscopy, and defined within three phenotypes (dysplasia of the fibrous sheath [DFS], primary flagellar dyskinesia [PFD] and non-specific flagellar abnormalities [NSFA]), have decreased chances of success in intracytoplasmic sperm injection (ICSI) or adverse obstetric and neonatal outcomes? DESIGN Retrospective analysis of 189 ICSI cycles from 80 men with spermatozoa flagellum ultrastructural defects (DFS [n = 16]; PFD [n = 14]; NSFA [n = 50] compared with a control group (n = 97). Cycles were cumulatively analysed. All fresh and frozen embryo transfers resulting from each ICSI attempt were included. The effect of transmission electron microscopy (TEM) phenotype on the main ICSI outcomes was assessed by a multivariate logistic regression combined with a generalized linear mixed model to account for the non-independence of the observations. RESULTS No predictive value of TEM phenotype was found on the main outcomes of ICSI, namely fertilization rates, pregnancy and delivery rates, and cumulative pregnancy and delivery rates. Cumulative pregnancy rates ranged from 29.0-43.3% in the different TEM phenotype subgroups compared with 36.8% in the control group. Cumulative live birth rates ranged from 24.6-36.7% compared with 31.4% in the control group. No increase was found in miscarriages, preterm births, low birth weights or birth abnormalities. CONCLUSIONS Data on the cumulative chances of success in ICSI of patients with ultrastructural flagellar defects, a rare cause of male infertility often associated with an underlying genetic cause, are reassuring, as are obstetrical and neonatal outcomes in this population.

Abstract
The manchette is a transient and unique structure present in elongating spermatids and required for proper differentiation of the germ cells during spermatogenesis. Previous work indicated that the MEIG1/PACRG complex locates in the manchette and is involved in the transport of cargos, such as SPAG16L, to build the sperm flagellum. Here, using co-immunoprecipitation and pull-down approaches in various cell systems, we established that DNALI1, an axonemal component originally cloned from Chlamydomonas reinhardtii, recruits and stabilizes PACRG and we confirm in vivo, the co-localization of DNALI1 and PACRG in the manchette by immunofluorescence of elongating murine spermatids. We next generated mice with a specific deficiency of DNALI1 in male germ cells, and observed a dramatic reduction of the sperm cells, which results in male infertility. In addition, we observed that the majority of the sperm cells exhibited abnormal morphology including misshapen heads, bent tails, enlarged midpiece, discontinuous accessory structure, emphasizing the importance of DNALI1 in sperm differentiation. Examination of testis histology confirmed impaired spermiogenesis in the mutant mice. Importantly, while testicular levels of MEIG1, PACRG, and SPAG16L proteins were unchanged in the Dnali1 mutant mice, their localization within the manchette was greatly affected, indicating that DNALI1 is required for the formation of the MEIG1/PACRG complex within the manchette. Interestingly, in contrast to MEIG1 and PACRG-deficient mice, the DNALI1-deficient mice also showed impaired sperm spermiation/individualization, suggesting additional functions beyond its involvement in the manchette structure. Overall, our work identifies DNALI1 as a protein required for sperm development.

Abstract
Echinococcosis disease shows clinical signs similar to many diseases. Hence we report cases that need to be confirmed using appropriate tests. A confirmatory study has been conducted to assess the accuracy of two cytopathological tests, with the histopathology test as the reference standard. The first cytopathological test evaluates the Ziehl Neelsen staining with an epifluorescence microscope (cytopath 1). The second cytopathological test uses the same staining followed by a transmitted light microscope examination (cytopath 2). Of a total of 2524 inspected pigs, 101 suspected cases of echinococcosis were detected, of which 67 were found positive with the two cytopathological tests and the histopathological one. The specificity of cytopath 1 (100 % [95 % CI 100 - 100]) and cytopath 2 (100 % [95 % CI 100;100]) were similar, as well as their respective positive predictive values: 100 % [95 % CI 100 - 100] vs. 100 % [95 % CI 100 - 100]. The sensitivity of cytopath 1 is 79.66 % [95 % CI 69.39 - 89.93], while cytopath 2 equals 66.10 % [95 % CI 54.02 - 78.18]. The difference in sensitivity of both tests was not significant. Negative predictive values found for cytopath 1, and cytopath 2 were 40 [95 % CI 18.53 - 61.47] and 28.57 [95 % CI 11.84 - 45.3], leading to the Generalized Estimating Equations (GEE) Model estimate for an odds ratio of 1.4 [95 % CI 0.41 - 5.2], p = 0.06. Cytopath 1 and cytopath 2 are equivalent in terms of specificity (100 % [95 % CI 100 - 100] vs. 100 % [95 % CI 100;100]) and positive predictive value (100 % [95 % CI 100 - 100]. Cytopath 1 is more sensitive than cytopath 2 but not significant (79.66 % [ 95 % CI 69.39 - 89.93] vs. 66.10 % [95 % CI 54.02 - 78.18]). However, the negative predictive value of cytopath 1 is better than that of cytopath 2: 40 % [95 % CI 18.53 - 61.47] vs. 28.57 % [95 % CI 11.84 - 45.3].

Abstract
BACKGROUND One out of ten deaths of children under five are attributable to indoor air pollution. And Acute Respiratory Illness (ARI) is among the direct causes. OBJECTIVE This study showed the possibilities of characterizing indoor air pollution in West African Economic and Monetary Union (WAEMU) area and it also made it possible to estimate its impact on the occurrence of ARI in children under five. METHODS It has been a secondary analysis based on Demographic and Health Surveys (DHSs) from WAEMU countries' data.. "Household level of air pollution" is the created composite variable, from questions on the degradation factors of indoor air quality (domestic combustion processes) which served to characterize indoor air pollution and to measure its impact by a logistic regression. RESULTS Burkina Faso stands out with a greater number of households with a high level of pollution (63.7%) followed by Benin (43.7%) then Togo (43.0%). The main exposure factor "Household level of air pollution" was associated with ARI symptoms (Togo: prevalence = 51.3%; chi-squared test's p-value < 0.001). Exposure to high level of pollution constitutes a risk (AOR [95 CI]), even though it is not significant ( Ivory Coast: 1.29 [0.72-2.30], Senegal: 1.39 [0.94-2.05] and Togo: 1.15 [0.67-1.95]) and this could be explained by the high infectious etiology of the ARI.

Abstract
Diarrheal diseases are the second leading cause of child mortality worldwide, occurring in about one in every nine child deaths, and were associated with water, sanitation, and hygiene (WASH) access. In this study, we provided an overview of WASH indicators' evolution from 2000 to 2017 and their impact on the occurrence of diarrhea in children under 5 years old in Senegal. It was a retrospective cross-sectional study, in which we did a secondary analysis of data from the Joint Monitoring Program (JMP) for water supply and sanitation and from the Senegal Demographic and Health Survey 2018. Our results showed that access to safely managed services increased by 18.1 and 19.1%, respectively, for water and sanitation. The prevalence of diarrhea estimated at 18.16% was associated with straining water through a cloth (adjusted odds ratio (AOR) [95% confidence interval (CI)]: 1.21 [1.00-1.45]) and getting water supplies from a source not located in a dwelling (AOR [95% CI]: 1.59 [1.21-2.09]). The prevalence of diarrhea among children under 5 years old was still relatively high in Senegal and was significantly associated with a lack of WASH access. Although the latter continues to increase, additional efforts to make water safer to drink will significantly reduce the occurrence of diarrheal diseases among children under 5 years old in Senegal.

Abstract
We report two observations of portal cavernoma diagnosed successively in Bamako and Dakar. The first is a 6-year-old male admitted to the service for ascites and abdominal pain. At admission the clinical parameters (weight, height, temperature, cranial perimeter and temperature) were within the norms for age. The clinical examination noted a moderate skin-mucosal pallor, asthenia. The biological assessment returned to moderate normochrome anemia with impaired pancreatic function while renal and hepatic functions were maintained. The abdominal scan performed after two low-contribution abdominal ultrasounds, objected signs in favor of a portal cavernoma with perisplenic and gastric varicose veins. The second is an 8-year-old male child born from an unborn marriage and from a followed pregnancy with premature delivery. His pathological history includes a notion of prematurity that required a stay in neonatology with umbilical catheterization and repeated abdominal pain. He had an acute abdominal episode in March 2015 justifying a surgical hospitalization for suspicion of appendicitis. At admission the clinical parameters (weight, height, temperature, cranial perimeter and temperature) were within the norms for age. The abdominal ultrasound prescribed for this was suggestive of portal cavernoma, later confirmed by abdominal computed tomography.

Abstract
STUDY QUESTION Are ICSI outcomes impaired in cases of severe asthenozoospermia with multiple morphological abnormalities of the flagellum (MMAF phenotype)? SUMMARY ANSWER Despite occasional technical difficulties, ICSI outcomes for couples with MMAF do not differ from those of other couples requiring ICSI, irrespective of the genetic defect. WHAT IS KNOWN ALREADY Severe asthenozoospermia, especially when associated with the MMAF phenotype, results in male infertility. Recent findings have confirmed that a genetic aetiology is frequently responsible for this phenotype. In such situations, pregnancies can be achieved using ICSI. However, few studies to date have provided detailed analyses regarding the flagellar ultrastructural defects underlying this phenotype, its genetic aetiologies, and the results of ICSI in such cases of male infertility. STUDY DESIGN, SIZE, DURATION We performed a retrospective study of 25 infertile men exhibiting severe asthenozoospermia associated with the MMAF phenotype identified through standard semen analysis. They were recruited at an academic centre for assisted reproduction in Paris (France) between 2009 and 2017. Transmission electron microscopy (TEM) and whole exome sequencing (WES) were performed in order to determine the sperm ultrastructural phenotype and the causal mutations, respectively. Finally 20 couples with MMAF were treated by assisted reproductive technologies based on ICSI. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients with MMAF were recruited based on reduced sperm progressive motility and increased frequencies of absent, short, coiled or irregular flagella compared with those in sperm from fertile control men. A quantitative analysis of the several ultrastructural defects was performed for the MMAF patients and for fertile men. The ICSI results obtained for 20 couples with MMAF were compared to those of 378 men with oligoasthenoteratozoospermia but no MMAF as an ICSI control group. MAIN RESULTS AND THE ROLE OF CHANCE TEM analysis and categorisation of the flagellar anomalies found in these patients provided important information regarding the structural defects underlying asthenozoospermia and sperm tail abnormalities. In particular, the absence of the central pair of axonemal microtubules was the predominant anomaly observed more frequently than in control sperm (P < 0.01). Exome sequencing, performed for 24 of the 25 patients, identified homozygous or compound heterozygous pathogenic mutations in CFAP43, CFAP44, CFAP69, DNAH1, DNAH8, AK7, TTC29 and MAATS1 in 13 patients (54.2%) (11 affecting MMAF genes and 2 affecting primary ciliary dyskinesia (PCD)-associated genes). A total of 40 ICSI cycles were undertaken for 20 MMAF couples, including 13 cycles (for 5 couples) where a hypo-osmotic swelling (HOS) test was required due to absolute asthenozoospermia. The fertilisation rate was not statistically different between the MMAF (65.7%) and the non-MMAF (66.0%) couples and it did not differ according to the genotype or the flagellar phenotype of the subjects or use of the HOS test. The clinical pregnancy rate per embryo transfer did not differ significantly between the MMAF (23.3%) and the non-MMAF (37.1%) groups. To date, 7 of the 20 MMAF couples have achieved a live birth from the ICSI attempts, with 11 babies born without any birth defects. LIMITATIONS, REASONS FOR CAUTION The ICSI procedure outcomes were assessed retrospectively on a small number of affected subjects and should be confirmed on a larger cohort. Moreover, TEM analysis could not be performed for all patients due to low sperm concentrations, and WES results are not yet available for all of the included men. WIDER IMPLICATIONS OF THE FINDINGS An early and extensive phenotypic and genetic investigation should be considered for all men requiring ICSI for severe asthenozoospermia. Although our study did not reveal any adverse ICSI outcomes associated with MMAF, we cannot rule out that some rare genetic causes could result in low fertilisation or pregnancy rates. STUDY FUNDING/COMPETING INTEREST(S) No external funding was used for this study and there are no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
Duplication of the inferior vena cava is a rare malformation, normally without clinical impact, explained by abnormal development and regression of certain segments of the venous system during embryonic life. However, its presence and type should be systematically reported in the radiological report because of its potential implications for diagnostic and interventional procedures. This observation describes the case of a 77-year-old man with a complete asymmetric duplication of the inferior vena cava (type III IVC according to Natsis) that was incidentally discovered on CT-scan.

Abstract
Study question
What are the feasibility and outcome of ICSI in case of presumably genetic severe asthenozoospermia with Multiple Morphological Abnormalities of the Flagellum (MMAF phenotype)?
Summary answer
ICSI outcome for couples with MMAF phenotype does not differ from that of other couples requiring ICSI, regardless to the genetic etiology
What is known already
Severe asthenozoospermia, especially when associated with multiple morphological abnormalities of the sperm flagellum (MMAF phenotype), results in male infertility. Recent findings confirm that a genetic etiology is frequently responsible for this phenotype. In such situations, pregnancies can be obtained using ICSI. However, few studies have provided detailed analyses of the flagellar ultrastructural defects underlying this phenotype, of its genetic etiologies and of the results of ICSI in such cases of male infertility.
Study design, size, duration
We performed a retrospective study including 25 infertile men showing severe asthenozoospermia associated with a MMAF phenotype identified through standard semen analysis. These men were recruited from an academic center for Assisted Reproduction in Paris between 2009 and 2017. Transmission electron microscopy (TEM) and Whole Exome Sequencing (WES) were performed in order to precise the sperm ultra-structural phenotype and identify causal mutations, respectively. Twenty of the 25 patients benefited from assisted reproductive therapy by ICSI.
Participants/materials, setting, methods
MMAF patients were recruited based on reduced sperm progressive motility and increased frequencies of absent, short, coiled or irregular flagella, in comparison with fertile control men. A quantified analysis of the ultrastructural defects was performed for the MMAF patients and for fertile control men. ICSI results for the MMAF patients were compared to those of 528 ICSI attempts performed for non-MMAF individuals considering the sperm parameters and the distribution of ultrastructural axonemal anomalies.
Main results and the role of chance
Thorough categorization by TEM analysis of the flagellar anomalies found in these patients brought important precisions about the structural defects underlying asthenozoospermia and sperm tail abnormalities detectable through standard microscopy. In particular, absence of the central pair of axonemal microtubules was the predominant anomaly, observed significantly more frequently than in control men (p < 0.01). Exome sequencing performed for 24 of the 25 patients (96%), identified in ten of them homozygous or compound heterozygous mutations that were described to be pathogenic (CFAP43, CFAP44, CFAP69, DNAH1, DNAH8, AK7, TTC29, MAATS1). A majority of those patients (55.5%,5/9) displayed the most severe ultra-structural defects of the axoneme. Forty ICSI attempts were performed for 20 MMAF patients. A hypo-osmotic swelling (HOS) test was required in 13 cycles (5 couples). Fertilization rate in MMAF group (65.7%) was not statistically different from the rate obtained for non-MMAF patients (66.0%) and did not differ according to the flagellar phenotype, nor to the use of HOS test, nor to the genotype. Clinical pregnancy rate per embryo transfer did not significantly differ between the MMAF group (23.3%) and the ICSI control group (37.1%). To date, 11 healthy babies were born among 20 MMAF patients.
Limitations, reasons for caution
The outcome of ICSI procedure was retrospectively assessed on a small sample and may be susceptible to recall bias. Moreover, TEM analysis was not available for some of the patients due to too low sperm concentration, and WES results are not yet available for all men included.
Wider implications of the findings
Couples requiring ICSI for presumably genetic severe asthenozoospermia should benefit precociously from appropriate phenotypic and genetic investigations. So far ICSI results appear similar to those observed in other ICSI indications. Identifying a genetic etiology and its mode of inheritance allows providing to these couples a most often reassuring genetic counseling.

Abstract
Background:The tremendous size of the 2013-2016 West African outbreak of Ebola virus disease (EVD) resulted in a sizeable population of survivors, many reporting short-term sequelae such as arthralgia and myalgia.Objectives:We aimed to report a detailed and long-term description of patients’ musculoskeletal (MS) symptoms.Methods:We performed a cross-sectional study following systematic rheumatological screening of patients included in the Postebogui cohort (Conakry district). We used regression models to establish the magnitude of EVD as a risk factor for developing chronic MS pain by comparison with a control cohort and to establish risk factors for developing MS pain among survivors.Results:The study included 313 patients (55.6% female), with a median age of 28.2 years (IQR 21-37), and a median time from ETC discharge to rheumatological visit of 26.2 months (IQR 23-30). Chronic MS pain was reported in 216 (69%) patients, and was predominantly mechanical (48%). Enthesis and painful peripheral joints were largely involved (91%) with symmetrical distribution. Previous Ebola infection was a major risk factor for chronic MS pain (aOR, 6.662 [95% CI, 4.522–9.921]). Among survivors, increasing age (OR 1.14, 95% CI 1.08-1.22) and female gender (OR 3.58, 95% CI 1.22-11.80) were both associated with persistent MS pain, while myalgia experienced during the acute phase of EVD appeared protective (OR 0.14, 95% CI 0.04-0.42).Conclusion:Our study provides the most accurate long-term description of MS disorders among Ebola survivors. Joint and muscle pain sequelae are frequent and require specialized care.Disclosure of Interests:None declared

Abstract
Erectile dysfunction is a common pathology in the general population. The frequency of these erectile disorders is increased in some particular populations such as patients with renal impairment in which it is estimated between 50% and 70% depending on the stage of renal failure. AIMS Our study aims to study erectile dysfunction in chronic hemodialyzed male patients. METHOD This is a descriptive prospective study carried out during the period from April 3 to August 31, 2017 having covered 65 chronic hemodialyzed patients for more than 12 months. RESULT In our study the prevalence of DE was 70.8% and moderate in 13.8%, severe in 30.8%, mild in 26.2%. Testosteronemia was normal in 83.1% of cases and significantly lower in patients with sexual disorders p = 0.030. Libido disorders were observed in 57% of our patients and significantly related to a decrease in testosteronemia p = 0.001. Vascular nephropathy was the most common etiology, i.e. 50.8% of cases followed by chronic Glomerulonephritis 24.6% and in 13.8% of cases no underlying etiology was found.

Abstract
For a long time, pregnancy in chronic hemodialysis was considered medically contraindicated, because of the many maternal complications that it could cause. Its management is as heavy for the medical teams (nephrologist, obstetrician and neonatologist) as for the patient herself. We report here a case of pregnancy in a dialysis patient observed at the Madeleine clinic in Dakar, Senegal. This pregnancy is the first described with a birth of a living child having a normal birth weight without abnormal malformative thanks to the multidisciplinary follow-up nephrologist, obstetrician and neonatologist), the intensification of dialysis care, the correction of anemia, control of blood pressure and improvement of the mother status nutritional.

Abstract
The decision to extract the last teeth represents for the patient an aesthetic, functional and moral damage. The realization of an immediate complete removable denture is indicated to remedy these difficulties. This will make it possible to ensure a rational and efficient management of this transition to total edentulous. The restorations of aesthetics and functions as well as patient comfort constitute the essential therapeutic objectives to be achieved and this thanks to the immediate denture. This work presents, through clinical cases, the indications and the management of four patients who have never worn a removable denture.

Abstract
Infertility, defined by the inability of conceiving a child after 1 year is estimated to concern approximately 50 million couples worldwide. As the male gamete is readily accessible and can be studied by a simple spermogram it is easier to subcategorize male than female infertility. Subjects with a specific sperm phenotype are more likely to have a common origin thus facilitating the search for causal factors. Male infertility is believed to be often multifactorial and caused by both genetic and extrinsic factors, but severe cases of male infertility are likely to have a predominant genetic etiology. Patients presenting with a monomorphic teratozoospermia such as globozoospermia or macrospermia with more than 85% of the spermatozoa presenting this specific abnormality have been analyzed permitting to identify several key genes for spermatogenesis such as AURKC and DPY19L2. The study of patients with other specific sperm anomalies such as severe alteration of sperm motility, in particular multiple morphological anomalies of the sperm flagella (MMAF) or sperm unability to fertilize the oocyte (oocyte activation failure syndrome) has also enable the identification of new infertility genes. Here we review the recent works describing the identification and characterization of gene defects having a direct qualitative effect on sperm morphology or function.

Abstract
Azoospermia, defined by the absence of sperm in the ejaculate, is estimated to affect up to 1% of men in the general population. Assisted reproductive technologies have revolutionized the treatment of infertility, and some azoospermic men, those with a post-meiotic defect, can conceive following the use of viable spermatoza recovered from testicular or epididymal biopsies. Although male infertility is a multifactorial disease, it is believed that genetic factors are predominant in the etiology of azoospermia and severe oligozoospermia. Despite that assumption, substantiated by the high number of infertile knockout (KO) mice and the even higher number of genes expressed essentially in the testis, little is known about the pathophysiology of reduced sperm production, its primary causes or the genetic and epigenetic consequences for the gamete and the future conceptus. The identification of genetic abnormalities is therefore paramount to understand spermatogenesis, to adopt the best course of action for the patient and to provide adequate genetic counseling. We provide here a review of the recent literature on the genetics of azoospermia and oligozoospermia, focusing on defects directly altering sperm production. New sequencing technologies are contributing to the rapid evolution of the recent field of infertility genetics.

Abstract
Isoniazid (INH), recommended by WHO (World Health Organization) in the treatment of tuberculosis (TB), is metabolized primarily by the genetically polymorphic N-acetyltransferase 2 (NAT2) enzyme. The human population is divided into three different phenotypic groups according to acetylation rate: slow, intermediate, and fast acetylators. The objective of this study was to explore the relationship between NAT2 genotypes and the serum concentrations of INH. Blood samples from 96 patients with TB were taken for the analysis. NAT2 polymorphisms on coding region were examined by polymerase chain reaction (PCR) direct sequencing; the acetylation status was obtained by measuring isoniazid (INH) and its metabolite, acetylisoniazid (AcINH) in plasma was obtained by using the liquid chromatography coupled to mass spectrometry. TB patients were distributed into two groups of fast and slow acetylators according to the acetylation index calculated based on the plasma concentration of INH in the 3rd hour (T3) after an oral dose. Our PCR analysis identified several alleles, where NAT2*4, NAT2*5A, NAT2*6A, and NAT2*13A were the most important. The concentrations of INH varied between 1.10 mg/L and 13.10 mg/L at the 3rd hour and between 0.1 and 9.5 mg/L at the 6th hour. The use of the acetylating index I3 allowed the classification of tested patients into two phenotypic groups: slow acetylators (44.3% of TB patients), and rapid acetylators (55.7%). Patient’s acetylation profile provides valuable information on their therapeutic, pharmacological, and toxicological responses.

Abstract
The purpose of the study was to determine Pb and Cd concentrations in humans and to assess the effect of co-exposure to these metals on biomarkers of oxidative stress and nephrotoxicity. Blood and urine levels of Pb and Cd, oxidative stress and urinary renal biomarkers were measured in 77 subjects neighboring a discharge and 52 in the control site. Exposed subjects showed significantly higher levels of lead and cadmium in blood and urine than the controls. Excessive production of reactive oxygen species induced by these metals in exposed subjects conducted to a decrease in antioxidant defense system (GPx, Selenium, GSH) and an increase in lipid peroxidation (MDA). Moreover, changes in markers of nephrotoxicity (high urinary concentrations of total protein, RBP and CC16, as well as GSTα and LDH increased activities) suggested the occurrence of discrete and early signs of impaired renal function for the discharge neighboring population.

We emphasize the role of imaging (X-ray and CT scan) in this work. The definitive diagnosis is confirmed by the pathological examination of biopsy samples. This location should be known in endemic tuberculosis areas.

Abstract
INTRODUCTION Prosthetic teeth size and placement must be in perfect harmony with the bucco-facial structures for a successful and esthetic removable prosthesis. This study aimed to determine among young Senegalese black people facial index estimating maxillary central incisor width and distance between canine points starting from bizygomatic width. PATIENTS AND METHODS 621 black Senegalese participated to this transversal study. Measurements were made using anthropometric slide caliper and electronic slide caliper. The comparative analysis was carried out by the test t of Student. The correlative analysis used the chi-square test. The risk of error was fixed at 5%. RESULTS Positive correlations were found between variables. Distance between canine points was significantly (p = 0.000) correlated to bizygomatic width and central incisor width. Using bizygomatic width, the average dividing factors to estimate central incisor width and distance between canine points were respectively 15.13 and 3.75. CONCLUSION Distance between canine points and central incisor width can be given starting from bizygomatic width, as guide of selecting maxillary anterior prosthetic teeth width.

Abstract
We report four cases of uterine fistula found with the multidetector CT virtual hysterosalpingography. Patients were received for suspicious of a utero-peritoneal fistula at hysterosalpingography. They were young people at childbearing age (average age of 33 years), multigravidae, two of whom were nulliparous, one primiparous and one multiparous. We noted a history of voluntary interruption of pregnancy by curettage and a cesarean section. For the opacification, we used the classic hysterography standard equipment by means of 1/5 diluted iodine with saline solution as contrast. The multidetector CT virtual hysterosalpingography revealed small uterine perforations including three which were located in uterine posterior face at cervico-isthmic area and corporeal area, bringing about a utero-peritoneal fistula. The multidetector CT virtual hysterosalpingography is a simple and powerful technique for the diagnosis of utero-peritoneal fistula. It is convenient and then deserves an important place in the evaluation of uterine fistula.

Abstract
AIMS The aim of this study was to determine sociodemographics, clinical and therapeutic aspects in patients with isolated mandibular fractures in the Bamako dentistry teaching hospital (CHU-OS). MATERIALS AND METHODS We carried out restrospective study over a period of four months involving isolated mandibular fracture cases, confirmed by a clinical and radiological examination in 2006. The data were collected from medical records, entered and analyzed using Epiinfo.fr 6.0 software. RESULTS The lesions involved 42 men and 13 women with a sex ratio of 3.23. The age group of 21-30 was the most affected. The main cause was found to be road traffic accidents with 72.72 % of the total cases. The fractures of the mandible at the level of horizontal branch were the most frequent with 34.54 %. The orthopedic treatment was used in 72.72 % of the cases, with a good and very good results. CONCLUSION This study shows the high frequency of isolated fractures of the mandible mainly from road traffic accidents, as well as their occurrence among young adults.

Abstract
The annulus is an electron-dense ring structure connecting the midpiece and the principal piece of the mammalian sperm flagellum. Proteins from the septin family have been shown to localize to the annulus. A septin complex is assembled early in spermiogenesis with the cochaperone DNAJB13 and, in mature sperm, associates with Testis Anion Transporter 1; SLC26A8 (Tat1), a transmembrane protein of the SLC26 family. Studies in mice have shown that the annulus acts as a barrier to protein diffusion and controls correct organization of the midpiece. Consistent with these findings, absence of the annulus is associated with flagellum differentiation defects and asthenozoospermia in humans.

Abstract
Ectopic pregnancy is one of the most frequent hemorrhagic emergencies encountered in gynecology and obstetrics. The purpose of this 16-month descriptive prospective study at the Ignace Deen Gynecology-Obstetric clinic at Conakry University Hospital in Guinea was to assess diagnostic techniques and therapeutic attitudes regarding ectopic pregnancy in a low-resource setting. The frequency of ectopic pregnancy was 1.4%. Mean patient age was 28.9 years. Ectopic pregnancy was often observed at the second or third pregnancy (47.1%) in women who were giving birth for the second or third time (36.0%) and had a history of sexually transmitted infections (88.2%) or abortions (43.1%). Most women had no schooling (60.8 %), were poor and lived in a marital home (86.3%). Presenting symptoms included the classic triad of amenorrhea (98.0%), abdominopelvic pain (92.2%), and vaginal bleeding (62.7%). Definitive diagnosis was achieved by ultrasound examination in 76.6% of cases and by puncture of the Douglas pouch in 84%. The most frequent site of ectopic pregnancy was the ampulla of the uterine tube (66.9%). Abdominal and ovarian pregnancy was observed in 3 and 4 of the 51 cases respectively. Surgical management was performed in all cases. The most frequent procedure was salpingectomy (80.3%). Proper treatment of sexually transmitted infections (STI), start-up of post-abortion care facilities, and provision of information during early consultation at the first signs of pregnancy would help reduce the frequency and improve the prognosis of ectopic pregnancy.

Abstract
RhoGTPases (Rho, Rac, and Cdc42) are known to regulate multiple functions, including cell motility, adhesion, and proliferation; however, the signaling pathways underlying these pleiotropic effects are far from fully understood. We have recently described a new RhoGAP (GTPase activating protein for RhoGTPases) gene, MgcRacGAP, primarily expressed in male germ cells, at the spermatocyte stage. We report here the isolation, through two-hybrid cloning, of a new partner of MgcRacGAP, very specifically expressed in the male germ line and showing structural features of anion transporters. This large protein (970 amino acids and a predicted size of 109 kDa), we provisionally designated Tat1 (for testis anion transporter 1), is closely related to a sulfate permease family comprising three proteins in human (DRA, Pendrin, and DTD); it is predicted to be an integral membrane protein with 14 transmembrane helices and intracytoplasmic NH(2) and COOH termini. In situ hybridization studies demonstrate that Tat1 and MgcRacGAP genes are coexpressed in male germ cells at the spermatocyte stage. On testis sections, Tat1 protein can be immunodetected in spermatocytes and spermatids associated with plasma membrane. Two-hybrid and in vitro binding assays demonstrate that MgcRacGAP stably interacts through its NH(2)-terminal domain with the Tat1 COOH-terminal region. Expression of Tat1 protein in COS7 cells generates a 4,4'-diisothiocyano-2,2'-disulfonic acid stilbene and chloride-sensitive sulfate transport. Therefore we conclude that Tat1 is a novel sulfate transporter specifically expressed in spermatocytes and spermatids and interacts with MgcRacGAP in these cells. These observations raise the possibility of a new regulatory pathway linking sulfate transport to Rho signaling in male germ cells.

Abstract
Hemolytic uremic syndrome (HUS) is an nonexceptional complication of infectious gastroenteritis. No one has already been reported in Senegalese publications. We made a retrospective study of the record of 7 patients with HUS among 256 cases of children with bloody diarrhea presenting to the pediatric unit of Aristide Le Dantec between august 1998 and july 1999. The mean age of the children was 33,14+/-25 months and the weight was -2,29 DS. The diagnosis is supported by the findings of an acute renal failure with urea at 1,28+/-0,51g/ l and creatinine at 41,46+/-25,48mg/l. An hemolytic anemia was constant, the blood film revealed schizocytes. We found a thrombocytemia only in two cases. A hight white blood cell count (more than 50000/mm3) was noted in for cases. Only one child made a good recovery. We insist on preventing gastroenteritis and aggressive and adapted management of the HUS.

Abstract
Nearly 200 million people in the developing world are dependent or urban gardening for food and income. This practice has been accelerated by the droughts of recent decades which have forced more and more migrants into urban areas. Numerous potential health hazards have been attributed to urban gardening but the exact risks in Sahelian areas remain unclear. The purpose of this cross-sectional study was to evaluate the incidence of diarrhea at the Tel Zatar gardening site in urban Nouakchott, Mauritania. In addition, a case-control study was carried out to identify risk factors for diarrhea in function of gardeners' activity and living conditions. Statistical analysis was performed using univariate and logistical regression methods. The annual incidence of diarrhea ranged from 6.9 (IC95 p. 100 = 5.0-8.8) to 8.5 (IC95 p. 100 = 6.2-10.8) episodes per gardener and year. Multivariate analysis identified four significant risk factors. Two of these factors were unrelated to gardening, i.e., not having spent more than USD 3.50 the previous day (odds ratio (OR = 2.8, IC95 p. 100 = 1.01-7.81) and poor food hygiene (cooking outside (OR = 4.69, IC95 p. 100 = 1.06-20.83). The other two factors were regular consumption of raw vegetables (OR = 25.5, IC95 p. 100 = 2.0-32.0) and use of untreated well water (OR = 3.85, IC95 p. 100 = 1.08-14.29). Unprotected well water was the cause of 59.2 p. 100 of diarrheal episodes reported by gardeners at Tel Zatar. The results of this study confirm that vegetable production in urban gardens such as Tel Zatar is associated with health risks. Public health measures should address not only the garden sites but also domestic hygiene.
