RESUMO

OBJECTIVE: In the past, studies on antimicrobial resistance were carried out on pathogens in the clinical areas. However, since then, this phenomenon has become a general case both in the environment and in the food sector. This systematic review aimed to review the various scientific publications on the resistance of bacteria to antibiotics in foods in West Africa. METHODS: An extensive literature search was carried out through an electronic database including PubMed, Google Scholar, Research Gate, and African Journals Online (AJOL). Articles published from fifteen countries of the Economic Community of West African States (ECOWAS) between 2010 and 2020 on antibiotic resistance of foodborne pathogens were included in the study. The titles and abstracts of the retrieved articles and then the full texts of the selected articles were reviewed. RESULTS: Out of the 565 articles found in our initial research, 149 publications (26.55%) were considered suitable for inclusion in this review. Globally, 2018, 2019, and 2020 had more included papers (n = 21 to 25) than the other years. Of the 149 publications analyzed, four types of food commodities were identified as products of high consumption based on the number of publications in the field such as poultry (39/149), read-to-eat food (22/149), meat, and animal products (20/149). Most studies have shown that E. coli has the highest prevalence followed by Salmonella and Staphylococcus. Only 33 (22.14%) of the 149 publications were based on further molecular characterization of the isolates. Publications analyzed showed that the most prevalent detected genes were tet(A), tet(B), tet(C), tet(K) blaTEM, catA1, catA2, cmlA, blaCTXM and qnrA, qnrB, qnrS, parC, and qepA4. CONCLUSION: From these results, antibiotic use in the food areas must be strongly regulated, especially in developing countries, particularly in Africa. This highlights the need to implement suitable and appropriate control strategies to reduce complications and prevent the dissemination of resistant bacteria isolates in foods. One health antimicrobial resistance surveillance system in the region must be a great concern.

RESUMO

Introduction : L'hospitalisation en néphrologie n'avait pas fait l'objet de plusieurs études au Sénégal et les données sont limitées. Notre travail avait pour but de déterminer les facteurs associés à l'hospitalisation prolongée et à la mortalité en néphrologie. Patients et méthodes : Il s'agissait d'une étude observationnelle prospective de 5 mois incluant tous les patients hospitalisés dans le service durant au moins 24H. La durée d'hospitalisation (la période allant du jour d'admission dans la chambre d'hospitalisation au jour de sortie du patient) était dite prolongée si > 12 jours. Résultats : Quatre-vingt-dix-neuf patients ont été analysés durant cette période avec une durée moyenne en hospitalisation de 11,14 ± 9,89 jours. L'âge moyen était de 45,22 ± 18,03 ans avec un sex-ratio (H/F) de 0,62. Les anomalies biologiques étaient : l'hyponatrémie (62,36%), l'hypokaliémie (23,91%), l'hypocalcémie (25%), l'hyperphosphatémie (51,21%), l'anémie (92,30%), la CRP élevée (90,90%) et l'hypoalbuminémie (80,76%). La protéinurie moyenne était de 3,38 ± 3,35 g/24h avec 34,61% de protéinurie néphrotique. La mortalité hospitalière était de 25,25%. En analyse univariée, l'hospitalisation prolongée était associée à l'âge ≤ 45 ans (p = 0,018), aux patients non dialysés chroniques (p=0,034), à la transfusion sanguine (p=0,008) tandis que la mortalité était liée à l'âge de plus de 45 ans (p=0,032), le diabète (p=0,014), l'hypokaliémie (p=0,045) et l'hospitalisation prolongé (p=0,007). En analyse multivariée, les patients présentant des œdèmes et ceux ayant été transfusés avaient respectivement 2,89 et 3,9 fois plus de risque d'avoir une hospitalisation prolongée. Les patients diabétiques avaient 4,63 fois plus de risque de décès et ceux ayant été hospitalisés de plus de 12 jours avaient 0,14 fois de risque de décès. Conclusion : La durée d'hospitalisation était relativement prolongée avec une mortalité élevée. Cependant l'impact de certains facteurs a été démontré permettant ainsi de réduire la durée d'hospitalisation et le nombre de décès.


Introduction: Hospitalization in nephrology had not been the subject of several studies in Senegal and the data are limited. Our work aimed to determine the factors associated with prolonged hospitalization and mortality in nephrology. Patients and methods: This was a 5-month prospective observational study including all patients hospitalized in the department for at least 24 hours. The duration of hospitalization (the period from the day of admission to the hospital room to the day of the patient's discharge) was said to be prolonged if > 12 days. Results: Ninety-nine patients were analyzed during this period with an average hospital stay of 11.14 ± 9.89 days. The mean age was 45.22 ± 18.03 years with a sex ratio (M/F) of 0.62. The biological abnormalities were: hyponatremia (62.36%), hypokalemia (23.91%), hypocalcemia (25%), hyperphosphatemia (51.21%), anemia (92.30 %), elevated CRP (90.90%) and hypoalbuminemia (80.76%). The mean proteinuria was 3.38 ± 3.35 g/24h with 34.61% nephrotic proteinuria. Hospital mortality was 25.25%. In univariate analysis, prolonged hospitalization was associated with age ≤ 45 years (p = 0.018), chronic non-dialysis patients (p = 0.034), blood transfusion (p = 0.008) while mortality was related to age over 45 (p=0.032), diabetes (p=0.014), hypokalaemia (p=0.045) and prolonged hospitalization (p=0.007). In multivariate analysis, patients with edema and those who had been transfused were respectively 2.89 and 3.9 times more likely to have prolonged hospitalization. Diabetic patients had a 4.63 times greater risk of death and those who had been hospitalized for more than 12 days had a 0.14 times greater risk of death. Conclusion: The duration of hospitalization was relatively prolonged with high mortality. However, the impact of certain factors has been demonstrated, thus making it possible to reduce the duration of hospitalization and the number of deaths

RESUMO

Treatment of invasive fungal infections with Caspofungin is used as the first-line antifungal agents. The minimum inhibitory concentration value is a test which indicates the degree of sensitivity of a strain regarding a drug. However, no value of minimum inhibitory concentration for caspofungin is available because very variable value is obtained. In this work, we study the link with the adsorption phenomenon of CSF previously described in literature and the lack of minimum inhibitory concentration value. A systematic study of the impact of different parameters on CSF adsorption is reported. The effect of the nature of container material, the aqueous solution pH and the organic solvent proportion was studied. In addition, the possibility of using a coating agent to minimize the adsorption was assayed and evaluated. Results obtained showed the importance of the material used during the manipulation of CSF. The use of acidic pH aqueous solution or the addition of acetonitrile or methanol proportions (50 % and 70 %, respectively) were found efficient to avoid adsorption of CSF on glassware material, which is the relevant strategy for analytical samples of caspofungin. The treatment of HPLC glass vials and 96-well plates with N-(2-aminoethyl)-3-aminopropyltrimethoxysilane reduced the adsorption. The significant adsorption observed in this work especially with plastic materials, questions the results obtained before in different assays and explained the absence of MIC value.

RESUMO

The actual scenario in the fight against fungal infections forces researchers to carry through with resistance studies to improve the therapies. These studies, which are performed in cell culture media, need accurate and sensitive analytical methodologies. That is why, in this work, an analytical method for caspofungin (CSF) concentration determination in RPMI-1640 cell culture medium with on-line sample treatment was developed and validated. CSF concentration was determined by HPLC-FLD using a column-switching procedure. The chromatographic analysis was carried out in less than 10 min using a C8 column (4 × 4 mm, 5 µm) as extraction stationary phase and a HSS T3 column (4.6 × 100 mm, 5 µm) as the analytical column. The used mobile phases were mixtures of phase A: pH 2 (adjusted with TFA) aqueous phase and phase B: ACN. For the extraction, the composition was (95:5, A:B v/v) and for the analysis (60:40, A:B v/v), both done in isocratic elution mode. These chromatographic conditions allowed reaching a limit of quantification of 10 µg/L, using 100 µL of sample with an injected volume of 40 µL. The proposed method was successfully validated in terms of selectivity, carryover, linear concentration range, accuracy and precision according to the criteria established by the Food and Drug Administration. Available amount of CSF in RPMI-1640 solution was found critical. CSF concentrations remained stable up to 2 h at room temperature. The developed method was applied for the direct analysis of CSF concentrations from in vitro experiments in presence of C. glabrata (CAGL18). The results highlight the decrease of cell proliferation even if the CSF amount decreases too, which asks question about the real value of the efficient concentration for CSF antifungal activity.

RESUMO

INTRODUCTION: The brachial plexus consists of the ventral twigs of the last four cervical nerves and the first thoracic nerve. It ensures the motor and sensitive innervations of the thoracic limb. AIM: Our goal was to describe the brachial plexus of the cervical region to the middle third of the arm. METHODOLOGY: We conducted a prospective study at the anatomy Laboratory of the Faculty of Medicine and Dentistry in Bamako from September 2016 to October 2017. We dissected the brachial plexus (PB) of 13 fresh adult corpses on both sides. The inclusion criteria were: Fresh adult corpses with cervical regions and brachial without scarring. The injected or scar-carrying corpses were not included in the cervical and brachial regions. RESULTS: Twenty-six brachial plexus of which 18 bp in men and 8 bp in women were dissected. The average age of the subjects was 42 years (extreme: 18 and 70 years). We noted nerve block variations in 3.8%, fascicular in 3.8% and late terminal in 73.1%. The involvement of the anterior branch of the fourth spinal nerve (C4) was found in 46.2%. CONCLUSION: The brachial plexus is the seat of many anatomical variations whose knowledge is indispensable to treat its lesions.

RESUMO

INTRODUCTION: The aim of this study was to determine the sociodemographic, therapeutic, pathological and clinical aspects of patients with maxillary ameloblastoma at the University Hospital of Odonto-Stomatology (CHU OS) of Bamako. MATERIALS AND METHOD: We performed a retrospective and prospective study over three years (January 2007 - December 2010), examining cases of maxillary ameloblastoma, as confirmed by clinical, associated with radiology or anatomic pathology. Data was collected from medical records, then entered and analyzed using Epiinfo. RESULTS: Tumor lesions were found in 55 men and 43 women with a sex ratio of 1.27. Housewives represented the majority of cases with 35.7%. Maxillary radiography was performed on 96% of patients and biopsy in 66.3% of cases. The most common anatomical location was mandibular in 89.80% of cases, with the preferred area being the mandibular symphysis in 34.7% of cases. Conservative surgery was performed in 50% of patients and radical surgery in 26.5% of cases. CONCLUSION: This study has shown a high frequency of maxillary ameloblastoma, and the fundamental benefits of early treatment, in order to minimize recidivism.

RESUMO

But : Décrire le traitement chirurgical des goitres volumineux au CHU du Point G.Patients et méthodes : Il s'agissait d'une étude réalisée entre 2009 et 2014 au CHU du Point G. Elle a porté sur les goitres ayant une hauteur et ou une largeur supérieure ou égale à 10 centimètres.Résultats : Nous avons colligé les dossiers de 115 cas de goitres volumineux. Les patients étaient de sexe féminin dans 87,8% des cas. Nous avons trouvé une dyspnée dans 40% descas (n=46), une dysphonie dans 13,0% des cas (n=15) et une dysphagie dans 8,6% des cas(n=10). La hauteur moyenne de la tuméfaction a été de 12,1 cm ± 3,5 et la largeur moyenne de 14,4 cm ± 5,4. Les goitres étaient hyperthyroïdiens chez 21,7% des patients (n=25) et multinodulaires dans 96,5% des cas. Il y avait 3 cas de cancer de la thyroïde. Tous les cas d'hyperthyroïdie ont été équilibrés par un anti thyroïdien de synthèse associé au Beta bloquant et au lugol fort avant la chirurgie. Le traitement chirurgical a constitué en une thyroïdectomie subtotale dans 97,4% des cas (n=112) et une thyroïdectomie totale dans 2,6% des cas (n=3). Les suites opératoires ont été simples dans 81,7% des cas (n=94). 18,3% de complications ont été notées(hématome compressif, Dysphonie, Dyspnée, Hyperparathyroïdie, Hypothyroïdie). La mortalité post opératoire était nulle.Conclusion : Le traitement chirurgical passe par la connaissance de l'anatomie de la région cervicale et une technique de thyroïdectomie bien codifiée

RESUMO

Strain FF9T was isolated in Dakar (Senegal) from a blood-culture taken from a 16-month-old child. MALDI-TOF analysis did not allow for identification. After sequencing, strain FF9T exhibited 98.18% similarity with the 16SrRNA sequence of Paenibacillus uliginis. A polyphasic study of phenotypic and genomic analyses showed that strain FF9T is Gram variable, catalase-positive, and presents a genome of 4,569,428 bp (one chromosome but no plasmid) with 4,427genes (4,352 protein-coding and 75 RNA genes (including 3 rRNA operons). The G+C content is 45.7%. On the basis of these genomic and phenotypic data analyses, we propose the creation of Paenibacillus dakarensis strain FF9T.

RESUMO

Strain FF8(T) (= CSUR P860 = DSM 28259) was isolated in Dakar, Senegal, from the urine of a 65-year-old man with acute cystitis. This strain shows a similarity of sequence of 16S rRNA of 98.38% with Weeksella virosa, and its GenBank accession numbers are HG931340 and CCMH00000000. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis had a poor score, ranging from 1.32 to 1.56, that did not allow identification of the bacterium. Using a polyphasic study made of phenotypic and genomic analyses, strain FF8(T) was a Gram-negative, aerobic rod and a member of the family Flavobacteriaceae. The sequenced genome is 2 562 781 bp with one chromosome but no plasmid. It exhibits a G + C content of 35.9% and contains 2390 protein-coding and 56 RNA genes, including a complete rRNA operon. On the basis of these data, we propose the creation of Weeksella massiliensis sp. nov.

RESUMO

Strain FF6(T) was isolated from the cervical abscess of a 4-year-old Senegalese boy, in Dakar, Senegal. MALDI-TOF MS did not provide any identification. This strain exhibited a 95.17% 16S rRNA sequence identity with Necropsobacter rosorum. Using a polyphasic study including phenotypic and genomic analyses, strain FF6(T) was an aero-anaerobic Gram-negative cocobacillus, oxidase positive, and exhibited a genome of 2,493,927 bp (1 chromosome but no plasmid) with a G+C content of 46.2% that coded 2,309 protein-coding and 53 RNA genes. On the basis of these data, we propose the creation of Necropsobacter massiliensis sp. nov.

RESUMO

The intra- and inter-observer variability in delineation of the parotids on the kilo-voltage computed tomography (kVCT) and mega-voltage computed tomography (MVCT) were examined to establish their impact on the dose calculation during adaptive head and neck helical tomotherapy (HT). Three observers delineated left and right parotids for ten randomly selected patients with oropharynx cancer treated on HT. The pre-treatment kVCT and the MVCT from the first fraction of irradiation were selected to delineation. The delineation procedure was repeated three times by each observer. The parotids were delineated according to the institutional protocol. The analyses included intra-observer reproducibility and inter-structure, -observer and -modality variability of the volume and dose. The differences between the left and right parotid outlines were not statistically significant (p > 0.3). The reproducibility of the delineation was confirmed for each observer on the kVCT (p > 0.2) and on the MVCT (p > 0.1). The inter-observer variability of the outlines was significant (p < 0.001) as well as the inter-modality variability (p < 0.006). The parotids delineated on the MVCT were 10% smaller than on the kVCT. The inter-observer variability of the parotids delineation did not affect the average dose (p = 0.096 on the kVCT and p = 0.176 on the MVCT). The dose calculated on the MVCT was higher by 3.3% than dose from the kVCT (p = 0.009). Usage of the institutional protocols for the parotids delineation reduces intra-observer variability and increases reproducibility of the outlines. These protocols do not eliminate delineation differences between the observers, but these differences are not clinically significant and do not affect average doses in the parotids. The volumes of the parotids delineated on the MVCT are smaller than on the kVCT, which affects the differences in the calculated doses.

RESUMO

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.

RESUMO

Diarrheal diseases remain a leading cause of death with 14.7 million deaths in 2001 and 26% of global mortality worldwide according to WHO. Shigella species are prevalent in tropical areas; they are present all the year, with epidemic outbreaks in rainy season. Between 2001 and 2010 one hundred ninety (190) strains of Shigella flexneri isolated from National Senegalese Enterobacteriaceae Center located at the Pasteur Institute in Dakar were studied. Susceptibility was performed by antibiogram following the CASFM recommendations. Detection and characterization of integrons and resistance genes was done by PCR using specific primers and sequencing. Antibiotic susceptibility showed high percentage resistance to tetracycline: 95%, cotrimoxazole 60%, ampicillin 55%. Nineteen strains were cephalosporin resistant (10%). Two isolates were resistant to quinolones and one was imipenem resistant. Genes tet, dfr, cat, bla tem1 , bla oxa30 , bla shv , bla CTX-M , blakpc,bla IMP , gyrA, gyrB, parC and parE were detected on isolates. Integrons harbored genes resistance. The class 1 integron predominated followed by class 2 integron. Genes bla oxa30 , aadA1/aadA2 dfrA1, dfrA7 were found on class 1 integron. Class 2 integron showed three different types cassettes. No class 3 integron was detected. Genes dfrA1, dfrA7, sat, and aadA1 were harbouring by integrons. Antibiotic susceptibility showed that Shigella flexneri strains are resistant to the first line drugs used to treat shigellosis in Senegal. Resistance to 3rd generation of cephalosporins and fluoroquinolones emerged and is of great concern. These molecules must be used with caution in the treatment of shigellosis.

RESUMO

OBJECTIVE: To evaluate the management of postoperative pain in the Point G teaching hospital. PATIENTS AND METHODS: We carried out a prospective study, in 2008. Inclusion criteria for the personnel: be a staff member from the department of surgery or anaesthesia reanimation; willing to fill out the questionnaire. Inclusion criteria for patients: to be operated and hospitalized in one of the departments of surgery and anaesthesia reanimation. RESULTS: We collated the responses of 600 patients and 113 personnel. 92% of the patients underwent post-operative analgesia. The delay between the request and treatment of the patient was extensive in 92% of cases. The medical personnel and nursing staff had not received specific training on treating the pain in respectively 55% and 70% of cases. We noted an absence of informational support and of pre-established consensual protocols, written and validated on the management of postoperative pains. CONCLUSION: The treatment of the postoperative pains shows important shortcomings within the Point G teaching hospital and these insufficiencies are found across levels.


BUT: Evaluer la prise en charge de la douleur post opératoire au CHU du Point G. PATIENTS ET MÉTHODES: Il s'agissait d'une étude prospective réalisée en 2008. Critères d'inclusion du personnel: être agent dans l'un des services de chirurgie ou d'anesthésie réanimation, disposé à remplir le questionnaire proposé. Critères d'inclusion du patient: être opéré et hospitalisé dans l'un des services de chirurgie et d'anesthésie réanimation. RÉSULTATS: Il a été colligé 600 patients et 113 personnels. 92% des patients ont bénéficié de l'analgésie post opératoire. Le délai de traitement après la demande était long dans 92%. Les personnels médical et soignant n'ont pas reçu de formation spécifique sur la douleur dans respectivement 55% et 70%. Nous avons constaté une absence de support informationnel, de protocoles consensuels préétablis, écrits et validés sur la prise en charge post opératoire de la douleur. CONCLUSION: La prise en charge post opératoire de la douleur connait des lacunes importantes au sein du CHU du Point G et les insuffisances sont à tous les niveaux.

RESUMO

OBJECTIVE: To determine the incidence of postoperative peritonitis, and describe their clinical, paraclinical and therapeutic aspects. PATIENTS AND METHODS: This was a retrospective study conducted between 1980 and 2010 in the Department of Surgery B of the Point G University Hospital. It focused on all patients who underwent surgical intra-abdominal in the Surgery B department. RESULTS: We collected 25 cases of postoperative peritonitis, 84% were male subjects. The average age of patients was 37.2 years ± 17.0. The clinical picture was dominated by abdominal pain (92%), abdominal defense (92%), and fever (84%). Abdominal ultrasound played an important role in diagnosing 72% of cases. Etiologies were dominated by anastomotic leak (32%), infection of the collection phrenic, iatrogenic perforation (28%). Interventions made at surgery were: suture of the perforation or anastomotic recovery plus peritoneal cleansing and drainage in 36% of cases, peritoneal cleansing and drainage in 36%. There were postoperative complications in five patients. The mortality rate was 4%. CONCLUSION: Postoperative peritonitis are rare in our service. When they occur their rate of morbidity and mortality are high.


BUT: Les objectifs étaient de déterminer la fréquence des péritonites postopératoires, de décrire leurs aspects cliniques, paracliniques et thérapeutiques. PATIENTS ET MÉTHODES: Il s'agissait d'une étude rétrospective réalisée entre 1980 et 2010 dans le service de de chirurgie B du CHU du Point G.Elle a porté sur tous les malades hospitalisés ayant subi une intervention chirurgicale intra abdominale en chirurgie B. RÉSULTATS: Nous avons colligés 25 cas de péritonites postopératoires dont 84% de sujet masculin. L'âge moyen des patients a été de 37,2 ans ±17,0. Le tableau clinique était dominé par la douleur abdominale (92%), la défense abdominale (92%), la fièvre (84. L'échographie abdominale a contribué au diagnostic dans 72% des cas. Les étiologies étaient dominées par la désunion anastomotique (32%), la collection infectée sous phrénique, la perforation iatrogène (28%). Les gestes réalisés à l'intervention chirurgicale étaient la suture de la perforation ou la reprise de l'anastomose plus une toilette péritonéale et un drainage dans 36%, la toilette péritonéale et drainage dans 36%. Les suites opératoires ont été compliquées chez cinq malades. La mortalité a été de 4%. CONCLUSION: Les péritonites postopératoires sont rares dans notre service. Quand elles surviennent leurs taux de morbidité et de mortalité sont élevés.

RESUMO

OBJECTIVE: To study the therapeutic aspects and prognosis of volvulus of the sigmoid colon in surgical departments. PATIENTS AND METHODS: Our study was retrospective from January 2000 to December 2009 (10 years). All patients who underwent sigmoid volvulus in the Point G teaching hospital surgical departments were taken into account. RESULTS: We recorded 96 patients operated for volvulus of sigmoid over 882 cases of bowel obstruction, a rate of 10.9%. The average age was 47.2 years ± 18.9. In per-operative, there was a necrosis of the colon rate of 16.7% (14 cases). Performed surgical treatment modalities were: sigmoidectomy with primary anastomosis in 29.2% of cases (28), sigmoidectomy followed by colostomy and secondary anastomosis in 60.4% of patients (58) and 10.4% rare of simple devolvulation. The immediate postoperative period were marked by a morbidity rate of 7.3% (7 cases) and a mortality rate of 7.3% (7 cases). CONCLUSION: In spite of various therapeutic modalities of volvulus of the sigmoid colon, the rates of postoperative morbidity and mortality are rising in the general surgery of the Point G teaching Hospital.


OBJECTIF: Le but était de décrire les aspects thérapeutiques et de déterminer le pronostic du volvulus du côlon sigmoïde dans les services de chirurgie générale. PATIENTS ET MÉTHODES: Notre étude a été rétrospective allant de janvier 2000 à décembre 2009 (soit 10 ans). Tous les patients opérés dans les services de chirurgie générale du CHU du Point G pour volvulus du sigmoïde ont été pris en compte. RÉSULTATS: Nous avons enregistré 96 patients opérés pour volvulus du sigmoïde sur 882 cas d'occlusion intestinale soit une fréquence de 10,9%. La moyenne d'âge était de 47,2 ans ±18,9 ans. En per-opératoire, il y avait une nécrose de l'anse volvulée chez 16,7% (14 cas). Les modalités thérapeutiques chirurgicales effectuées ont été: la sigmoïdectomie avec anastomose immédiate dans 29,2% (28 cas), la sigmoïdectomie suivie de colostomie puis anastomose secondaire dans 60,4% (58 cas) et la dévolvulation simple dans 10,4% (10). Les suites opératoires immédiates ont été marquées par un taux de morbidité de 7,3% (7) et un taux de mortalité de 7,3% (7). CONCLUSION: En dépit des modalités thérapeutiques variées du volvulus du côlon sigmoïde, les taux de morbidité et de mortalité postopératoires restent élevés dans les services de chirurgie générale du CHU du Point G.

RESUMO

The purpose of this study was to describe the common mesentery in its occlusive form and practice driving before this emergency. The mesentery is a common abnormality of rotation of the primitive intestinal loop or omphalomesenteric loop during embryonic development.Two cases of intestinal obstruction by strangulation were received in urgency. They were a 55 year old man who checked himself into the emergency department and a 14 year old girl brought in by her parents. These were 2 cases of acute intestinal obstruction on incomplete common mesentery. The intestine was turned to complete common mesentery in both cases. Embryologically, it is anomalies of rotation and joining of the primitive intestine that are causing the incomplete common mesentery , the source of acute intestinal obstruction due to strangulation. CONCLUSION: The common mesentery poses a diagnostic and therapeutic problem. Its symptomatology is that of occlusion by strangulation and the surgeon must note this before any obstruction.


Le but de cette étude était de décrire le mésentère commun dans sa forme occlusive et la conduite pratique devant cette situation urgente. Le mésentère commun est une anomalie de rotation de l'anse intestinale primitive ou anse omphalomésentérique, lors du développement embryonnaire.Deux cas d'occlusion intestinale par strangulation ont été reçus en urgence. Il s'agissait d'un homme de 55 ans venu de lui-même dans le service d'accueil des urgences et d'une fillette de 14 ans amenée par ses parents. Il s'agissait de 2 cas d'occlusion intestinale aiguë sur mésentère commun incomplet. L'intestin a été mis en mésentère commun complet pour les 2 cas. Embryologiquement ce sont les anomalies de rotation et d'accolement de l'anse intestinale primitive qui sont à l'origine du mésentère commun incomplet, source d'occlusion intestinale aiguë par strangulation. CONCLUSION: Le mésentère commun pose un problème diagnostique et thérapeutique. Sa symptomatologie est celle d'une occlusion par strangulation et le chirurgien doit y penser devant toute occlusion.

RESUMO

There is no data available on the ABO/Rh(D) frequencies in the Mauritanian population. We retrospectively analysed records of a 5-year database that contained ABO/Rh phenotype and ethnic origin of 10 116 volunteers giving blood at the national blood transfusion centre to derive the frequencies of ABO/Rh(D) groups in the Mauritanian population. The two race categories in the country and their sub-ethnic groups: the Moors (whites and black) and the black Africans (Pulhars, Soninkes and Wolof) were included in this study. Globally, group O had the highest frequency (49.10%) followed by A (28.28%), B (18.56%) and AB (4.05%). This order more common in North African populations was found in four of the five ethnic groups composing our population. Allele frequencies were, respectively, 70.20%, 17.74% and 12.04% giving the same order of O > A > B. We observed no significant variation in these frequencies between the different ethnic groups. Rhesus study showed that with a percentage of 94.23% Rh(D) positive is by far the most prevalent, while Rh(D) negative is present only in 5.77% of the total population. This frequency distribution supports the mixed-race composition of the Mauritanian population.
