Risk factors for loss to follow-up, transfer or death among people living with HIV on their first antiretroviral therapy regimen in Mali.

OBJECTIVES: Risk factors for loss to follow-up (LTFU) were assessed for people living with HIV (PLHIV) at various reference out-patient clinics (expertise level II) and hospitals (expertise level III) in Mali. METHODS: HIV-1-positive adults starting antiretroviral therapy (ART) in 2006-2013 were eligible for inclusion. Risk factors for LTFU, defined as no visit in the 6 months preceding the last database update, were assessed with the Cox model, taking into account the competing risks of transfer and death. Potential risk factors at the start of ART were demographic and socioeconomic variables, World Health Organization (WHO) stage, CD4 count, period of ART initiation, type of ART, region of care, expertise level and distance from home. RESULTS: We included 9821 PLHIV, 33% of whom were male, starting ART at nine out-patient clinics and seven hospitals [five and two in the capital Bamako and four and five in the 'regions' (i.e. districts outside the capital), respectively] with a median (interquartile range) CD4 count of 153 (56-270) cells/µL. Five-year cumulative incidences of LTFU, transfer and death were 35.2, 9.7 and 6.7%, respectively. People followed at Bamako hospitals > 5 km from home, at regional hospitals or at regional out-patient clinics < 5 km from home were at higher risk of LTFU than people followed at Bamako out-patient clinics, whereas people followed at regional out-patient clinics 5-50 km away from home were at lower risk for LTFU. Deaths were less frequent at hospitals, whether in Bamako or in the regions, than at Bamako out-patient clinics, and more frequent at regional out-patient clinics. CONCLUSIONS: Expertise level and distance to care were associated with LTFU. Stigmatization may play a role for PLHIV living close to the centres in the regions.

High level of HIV-1 resistance in patients failing long-term first-line antiretroviral therapy in Mali.

OBJECTIVES: In resource-limited settings, few data are available on virological failure after long-term first-line antiretroviral therapy. This study characterized the genotypic resistance patterns at the time of failure after at least 36 months of a first-line regimen in Mali, West Africa. METHODS: Plasma samples from 84 patients who were receiving first-line antiretroviral treatment and with an HIV-1 RNA viral load (VL) >1000 copies/mL were analysed. Genotypic resistance testing was performed and HIV-1 drug resistance was interpreted according to the latest version of the National Agency for HIV and Hepatitis Research algorithm. RESULTS: At the time of resistance testing, patients had been treated for a median of 60 months (IQR 36-132 months) and had a median CD4 cell count of 292 cells/mm(3) (IQR 6-1319 cells/mm(3)), a median HIV-1 RNA level of 28266 copies/mL (IQR 1000-2 93 495 copies/mL) and a median genotypic susceptibility score of 1 (IQR 1-4). The prevalence of nucleoside reverse transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance mutations was 78% and 82%, respectively. Viruses were resistant to at least one drug in 92% of cases. Although etravirine and rilpivirine were not used in the first-line regimens, viruses were resistant to etravirine in 34% of cases and to rilpivirine in 49% of cases. The treatment duration, median number of NRTI and NNRTI mutations and some reverse transcriptase mutations (T215Y/F/N, L210W, L74I, M41L and H221Y) were associated with the VL at virological failure. CONCLUSIONS: This study demonstrated a high level of resistance to NRTIs and NNRTIs, compromising second-generation NNRTIs, for patients who stayed on long-term first-line regimens. It is crucial to expand the accessibility of virological testing in resource-limited settings to limit the expansion of resistance and preserve second-line treatment efficacy.

Inactivation mechanisms of pathogenic bacteria in several matrixes during the composting process in a composting toilet.

This study aimed to compare the inactivation rate and the mechanisms of pathogenic bacteria in three matrixes (sawdust, rice husk and charcoal) during the composting process. The inactivation rate was evaluated with Escherichia coli strain and the damaged parts and/or functions were evaluated with three different media. Normalized inactivation rate constant in three media and from three matrixes had no significant difference in each process (pure, 1 month and 2 months). The value in rice husk was relatively increased during 2 months but there was no significant difference. The inactivation rate constants of Tryptic Soy Agar (TSA) and Compact Dry E. coli/Coliform in pure sawdust and rice husk were relatively lower than that of Desoxycholate Agar, but increased in 2 months. This indicated that damaging part was changed from outer membrane to enzymes and metabolisms during the 2-month composting process. In the case of charcoal, only the TSA value in apure matrix was relatively lower than that of others, but it increased in 2 months. This indicated that damaging part was changed from outer membrane and enzyme to metabolisms during the composting process. Composting matrix and composting process did not significantly affect inactivation rate of pathogenic bacteria during the process but affected the damaging part of the bacteria.

Designing slanted soil system for greywater treatment for irrigation purposes in rural area of arid regions.

To solve the unpleasant disposal of greywater in rural area and allow its collection for reuse in gardening, a slanted soil treatment system (SSTS) was designed and installed in two households. Granitic gravel of 1-9 mm size was used as the filter medium. The aim of this study was to design a SSTS and assess its suitability as a treatment system allowing greywater reuse in gardening. The efficiency of the SSTS was assessed based on organic matter and bacterial pollution removal. The developed SSTS allowed the collection of greywater from three main sources (shower, dishwashing and laundry) in rural area. The SSTS is efficient in removing at least 50% of suspended solids, chemical oxygen demand and biological oxygen demand. The study highlighted that, contrary to the common perception, greywater streams in rural area are heavily polluted with faecal indicators. The removal efficiency of faecal indicators was lower than 2 log units, and the bacteriological quality of the effluents is generally higher than the WHO reuse guidelines for restricted irrigation. Longer retention time is required to increase the efficiency. The possibility of reusing the treated greywater as irrigation water is discussed on the basis of various qualitative parameters. The SSTS is a promising greywater treatment system for small communities in the rural area in the Sahelian region. To increase the treatment efficiency, future research will focus on the characteristics of the SSTS, the grain size and the establishment of a pretreatment step.

Genetic barrier to the development of resistance to rilpivirine and etravirine between HIV-1 subtypes CRF02_AG and B.

OBJECTIVES: It has been demonstrated for some drugs that the genetic barrier, defined as the number of genetic transitions and/or transversions needed to produce a resistance mutation, can differ between HIV-1 subtypes. We aimed to assess differences in the genetic barrier for the evolution of resistance to the second-generation non-nucleoside reverse transcriptase inhibitors etravirine and rilpivirine in subtypes B and CRF02_AG in antiretroviral-naive patients. METHODS: An analysis was undertaken of 25 substitutions associated with etravirine and rilpivirine resistance at 12 amino acid positions in 267 nucleotide sequences (136 HIV-1 B and 131 HIV-1 CRF02_AG subtypes) of the reverse transcriptase gene. RESULTS: The majority (7/12) of amino acid positions studied were conserved between the two HIV-1 subtypes, leading to a similar genetic barrier. Different predominant codons between the subtypes were observed in 5/12 positions (90, 98, 179, 181 and 227), with an effect on the calculated genetic barrier only at the V179D and V179F codons (2.5 versus 3.5 for V179D, and 2.5 versus 5 for V179F, respectively, for subtype B versus subtype CRF02_AG). CONCLUSIONS: The majority of amino acids involved in etravirine and rilpivirine resistance showed a high degree of conservation of the predominant codon between the B and CRF02_AG subtypes. For rilpivirine, the genetic barrier was the same between the two subtypes. Nevertheless, subtype CRF02_AG showed a higher genetic barrier to acquiring mutations V179D and V179F (mutations associated with resistance to etravirine) compared with subtype B, suggesting that it would be more difficult to produce resistance to etravirine in the CRF02_AG subtype than the B subtype.

Clinical, paraclinical and genetic aspects of autosomal recessive cerebellar ataxias (ARCA) in Mali.

Introduction: Autosomal recessive cerebellar ataxias (ARCA) are a group of rare and heterogynous neurodegenerative diseases mainly characterized by unbalance and walking difficulty and movement incoordination. Objectives: To clinically and paraclinically characterize ARCA in the department of Neurology at the Teaching Hospital of Point G and identify the underlying genetic defect. Patients and method: We have conducted a longitudinal and prospective study from January 2018 to December 2020. Patients with ARCA phenotype seen in the Department of Neurology at the Teaching Hospital of Point "G" were enrolled. Results: We have enrolled 7 families totaling 13 patients after giving an informed verbal and written consent. The sex ratio was 2.2 in favor of males, Kayes region and Fulani ethnic group were respectively the most represented region and ethnic group.Walking difficulty represented the major symptom followed by loss of vibration and joint sense, nystagmus, dysarthria and skeletal deformities. Alpha-foetoprotein level was high in one patient. Genetic testing confirmed Friedreich ataxia in one family and was not conclusive in 4 families. Conclusion: This study showed that ARCA are not uncommon in Mali and genetic testing is crucial to confirm the diagnosis.

[Comparison of the performance of viral load screening from plasma and from the oneblotting paper (Oudried Blood Spot), protocol in people living with the human immunodeficiency virus (PLHIV) in Bamako]. / Comparaison des valeurs de charges virales realisees sur plasma et sur goutte de sang seche Oudried Blood Spot(DBS) chez les personnes vivant avec levirus de l'immunodeficience humaine (VIH) a Bamako.

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.

INTRODUCTION: L'utilisation du papier buvard comme support de quantification de la charge virale pourrait améliorer le suivi virologique des patients sous traitement antirétroviral (ARV) au Mali. L'urgence s'impose à nous vula couverture en charge faible(10%) pour l'atteinte du 3ème 90. OBJECTIF: Evaluer les performances de dépistage de la charge virale (sensibilité, spécificité, concordance) des DBS issus du protocole one spot DBS en fonction du plasma chez les personnes vivant avec le virus de l'immunodéficience humaine (PVVIH) à Bamako. MÉTHODES: Au total, 130 papiers buvards ont été confectionnés à partir d'échantillons sanguin reçus de cinq sites de suivi des personnes vivant avec le virus de l'immunodéficience humaine. Ces papiers buvards ainsi confectionnés ont été analysés avec l'appareil Abbott m2000 en vue de la quantification de la charge virale avec comme échantillon de référence le plasma. L'extraction a été faite avec l'extracteur automatique m2000SP, suivant le protocole 1.0 mL HIV-RNA DBS Protocol pour le papier buvard. Par ailleurs, l'extraction de l'acideribonucléique (ARN) plasmatique sur le m2000SP a été faite selon le protocole 0.6 mL HIV-1 RNA. RÉSULTATS: Avec les 130 échantillons avec des charges virales détectables, nous avons obtenu une corrélation de r= 0.837(p<0,001). Par ailleurs, la différence moyenne entre la charge virale sur papier buvard et sur plasma était de 0,512 log/copies virologique avec un coefficient kappa= 0,708. Le seuil de 1000 copies/mL défini comme succès virologique dans notre étude nous a permis d'obtenir une sensibilité de 100% et une spécificité de 87%. CONCLUSION: Dans les zones décentralisées où le suivi virologique sur plasma n'est pas accessible, le nouveau Protocol one spot du laboratoire Abbott offre une opportunité intéressante pour le suivi de ces patients avec de bonne performance au seuil des 1000 copies. Aussi, l'utilisation du DBS comme support virologique peut contribuer efficacement à l'atteinte du 3ème 90.

[Socio-demographic, clinical, and therapeutic aspects of adolescents treated and followed for HIV infection at the Hospital Gabriel Toure paediatric center]. / Profil epidemio-clinique et therapeutique du VIH de l'adolescent au departement de pediatrie du chu Gabriel Toure.

HIV infection is a chronic infectious disease requiring long-term management and regular follow-up of patients. OBJECTIVES: The aims of this study was to describe the socio-demographic, clinical, biological and therapeutic aspects of adolescents treated and followed for HIV infection at the Hospital Gabriel Toure paediatric center. PATIENTS AND METHODS: From 01/01/2001 to 31/12/2017, the medical records of children followed for HIV infection until adolescence were analyzed. It was a descriptive and analytical retrospective study. RESULTS: One thousand five hundred and fourteen patients received antiretroviral treatment and 587 were still in follow-up on 31 December 2017, including 393 adolescents (sex-ratio = 1.2). The median age was 14.25 years and 55.1% of children had lost at least one parent. HIV serology was positive among mothers in 61.7% of cases (n=342), and 63% of them were on ARVs. Sixty-eight per cent of children were WHO Stage III or IV at the time of ART initiation. The median age at onset of ART was 53 months (26-96 months). The combination of 2 nucleotide reverse transcriptase inhibitors (NRTIs) with a non-nucleotide reverse transcriptase inhibitor (NNRTI) was used in 89% of patients. The median CD4 count before ARV treatment was 438/mm3. The average duration of follow-up under treatment was 9.8 ± 3.4 years. Fifty-one percent of adolescents had undetectable viral load. There was a correlation between the initiation of a second line of treatment and treatment failure (p<0.001). CONCLUSION: The adherence of adolescents to ARV treatment requires the implementation of innovative strategies to improve the therapeutic success rate.

OBJECTIFS: L'objectif de ce travail était de décrire les aspects socio-démographiques, clinico-biologiques et thérapeutiques du VIH chez l'adolescentau centre d'excellence pédiatrique de prise en charge du CHU Gabriel Toure. PATIENTS ET MÉTHODES: Il s'agissait d'une étude transversale avec recueil rétrospectif de données, qui s'est déroulée du 01/01/2001 au 31/12/2017. C'était une étudetransversale à visée analytique portant sur les dossiers des adolescents d'au moins10 ans. RÉSULTATS: Trois cent quatre-vingt-treize (393) adolescents d'au moins10 ansont été inclus. La sérologie VIH était positive chez les mères dans 61,7% des cas (n=342), et 63% d'entre elles étaient sous ARV. Soixante-huit pour cent des enfants étaient classés stade III ou IV de l'OMS au moment de la mise sous TARV. L'association de 2 inhibiteurs nucléosidiques de la transcriptase inverse (INTI) à un inhibiteur non nucléotidique de la transcriptase inverse (INNTI) a été utilisée chez 89% des patients. Le taux de CD4 médian avant la mise sous traitement ARV était de 438/mm3 La durée moyenne de suivi sous traitement était de 9,8 ± 3,4 ans. Cinquante un pourcent (51%) des adolescents étaient en succès thérapeutique avec une charge virale indétectable (< 1000 copies/ml). Il y avait une corrélation entre l'instauration d'une seconde ligne de traitement et l'échec thérapeutique (p<0,001). CONCLUSION: L'adhésion des adolescents au traitement ARV nécessite la mise en place de stratégies innovantes permettant d'améliorer le taux de succès thérapeutique.

[Indications and results of pulmonary resections in a developing country]. / Indications et résultats des exérèses pulmonaires dans un pays en développement.

INTRODUCTION: Indications for pulmonary excision are dominated by infectious pulmonary pathologies in developing countries. We conducted this study to describe the indications and results of pulmonary resections in the thoracic surgery department of the Mali hospital. PATIENTS AND METHODS: This is a retrospective and descriptive study from January 2012 to December 2019, carried out in the thoracic surgery department of the Mali hospital. It involved 76 patients who had a pulmonary resection. The variables studied were the epidemiological data, the operating indications, the therapeutic data and the prognosis. RESULTS: The mean age of the patients was 35.5 years. The sex ratio was 1.7. The average consultation time in thoracic surgery was 11.6 months with extremes of 7 days and 96 months. A history of pulmonary tuberculosis was noted in 46.1% of patients. The main indications for pulmonary resection were infectious parenchymal destruction in 64.5%, bullous dystrophy in 14.5%, bronchopulmonary cancer in 11.8% and thoracic trauma in 4% of the cases. The procedures performed were: a lobectomy (39.5%), atypical resection (36.8%), culminectomy (7.9%) and pneumonectomy (15.8%). Morbidity was dominated by thoracic empyema (9.2%) postoperative hemorrhage (5.2%), parietal suppuration (7.8%) and bronchopleural fistula (1.3%). The average length of hospital stay was 14.3 days. Mortality was 10.5%. There was a statistically significant correlation between pneumonectomy and deaths (P=0.01). CONCLUSION: Infectious lung destruction is the main indication for pulmonary resection in Mali. The consultation period is quite long. Morbidity and mortality remains high.

[Clinical and laboratory features of recessive Limb Girdle Muscular dystrophies in the Department Neurology of University Hospital of Point G]. / Aspects Cliniques et Paracliniques des Myopathies des Ceintures Récessives au Service de Neurologie du CHU Point G.

INTRODUCTION: Limb-Girdle Muscular dystrophies (LGMD) is a group of inherited diseases characterized by predominantly proximal and limb muscle weakness. These are rare diseases that have not been well studied in sub-saharan Africa. The aim of our was the clinical and paraclinical characterization of patients with recessive LGMD at the Department of Neurology of the Teaching Hospital of Point G. PATIENTS AND METHODS: We conducted a longitudinal prospective study which took place from March 2014 to May 2019. Patients with recessive LGMD phenotype were enrolled. Sociodemographic, clinical and laboratory data were analyzed. RESULTS: We enrolled 46 families (67 patients), i.e. a frequency of 16.7% among the neurodegenerative diseases seen in the service. Among them, 45.6% came from the Sikasso region. Autosomal recessive inheritance pattern was suspected in 67.4% of the families. Symptoms appeared mainly in the first decade of life. Proximal muscle weakness was found in almost all patients. Cardiac examination showed dilated cardiomyopathy in 4.5% of cases. CONCLUSION: Limb-Girdle muscular dystrophy is a disabling disease that is found in Mali. Further study of these cases could elucidate the underlying genetic defects.

[Epidemiology of Covid-19 and high blood pressure association at Mali'shospital]. / Epidemiologie de l'association Covid-19 et hypertension arterielle a l'hopital du Mali.

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.

INTRODUCTION: L'hypertension artérielle (HTA) est un facteur de risque cardiovasculaire majeur. Dans la littérature elle est fréquemment retrouvée chez les patients atteints de la COVID-19.L'objectif de cette étude est de décrire l'épidémiologie de cette association chez les patients hospitalisés pour Covid-19. PATIENTS ET MÉTHODE: L'Etude est transversale et descriptive ; elle a été réalisée sur la période du 1erAvril 2020 au 30 Juin 2020. Elle a concerné les patients hospitalisés pour Covid 19 avec un test PCR positif à l'hôpital du Mali de Bamako et ayant une HTA. Les registres d'admission et les dossiers des patients ont servi pour la collecte des données. RÉSULTATS: Nous avons colligé 78 sur 484 patients hospitalisés soit une fréquence de 16,11%. L'âge moyen était de 55,21 +/- 14,61 ans. Le sex ratio H/F était de 1,36.Les patients étaient suivis pour HTA dans 59% des cas. Les antécédents médicaux étaient la cardiopathie ischémique chez 2,6% et la cardiomyopathie dilatée chez 2,6%. Les principaux signes fonctionnels étaient la toux chez 41,02% et l'agueusie chez 11,53%. L'HTA à l'admission était de grade 2 dans 37,2% des cas et de grade 3 dans 3,8% des cas. Les traitements reçus étaient les inhibiteurs calciques 41,02%, les inhibiteurs du système rénine angiotensine aldostérone 16,66% et les associations 15,38%. La mortalité hospitalière était de 10,3%. Il n'y avait pas de différence statistiquement significative concernant la mortalité entre les patients connus hypertendus et les patients hypertendus de novo. Il n'y avait pas non plus de différence statistiquement significative concernant la mortalité selon le grade de l'HTA. CONCLUSION: l'HTA peut être associée au Covid 19. Le traitement est basé sur les inhibiteurs calciques et sur les inhibiteurs du système rénine angiotensine aldostérone. Elle a un impact sur le pronostic de la maladie avec une mortalité importante.

Sludge accumulation in an anaerobic pond and viability of helminth eggs: a case study in Burkina Faso.

Accumulation rates and pathogen concentrations in primary stabilization pond sludges in developing countries are important parameters for adequate sludge management and the safeguarding of public health with sludge reuse in agriculture. An anaerobic pond has been investigated for sludge accumulation rates and helminth egg viability after four years of operation in Burkina Faso. The rate of sludge accumulation was measured at 0.037 m(3)/capita-year or 2.26 kg dry weight/capita-year. An equation describing vertical distribution of total solids in the accumulated sludge was found to be adequately represented by a regression equation. Influent helminth egg concentrations were reduced on average by 90% in the anaerobic pond effluent. Ascaris lumbricoides and Ancylostoma sp. were the most common eggs present in the sludge after four years of operation. The average concentration of helminth eggs in pond sludge was 536 eggs/g TS, and the percentages of viability ranged from 10.8% (47 viable eggs/g TS) to 57.2 (1,772 viable eggs/g TS, with an average rate of 36% (336 viable eggs/g TS). From a sludge depth and section study, egg viability was found to be randomly distributed in the sludge layer.

[Foreskin Cyst After Circumcision At The Hospital Of Sikasso (MALI)]. / Kyste Du Moignon Preputial Post Circoncision Traditionnelle A L'Hopital De Sikasso (MALI).

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.

Le kyste cicatriciel post circoncision du moignon du prépuce est une pathologie dont nous n'avons pas trouvé de cas dans la littérature. La circoncision traditionnelle est toujours pratiquée dans nos régions, avec son cortège de complications, notamment l'hémorragie, la section partielle ou totale du gland, les infections. Le kyste cicatriciel post circoncision traditionnelle que nous rapportons concerne un patient de 24 ans présentant un volumineux kyste de 08cm de diamètre, évoluant depuis 17ans. Le patient n'a informé ses parents que lorsque le désir de se marier est devenu très pressant. La consultation fut motivée par le traumatisme psychologique, la gêne et la douleur provoquée par l'infection et la fistulisation. Le traitement a été chirurgical avec des suites simples. Cette observation souligne l'importance de la maitrise de la bonne technique opératoire afin de minimiser les complications de la circoncision traditionnelle, elle met aussi la lumière sur le côté tabou des pathologies touchant la sphère uro-génitale.

[Health care-associated infections in teaching hospital Gabriel TOURE]. / Les infections associées aux soins dans le service de chirurgie generale du CHU Gabriel TOURE.

OBJECTIVES: To study health care-associated infections (HCAI) in teaching hospital Gabriel TOURE. METHODOLOGY: This was a prospective study of 6 months (from April to September 2016) which included patients admitted to the General Surgery Department, operated or not, except those who had undergone a necrosectomy. The criteria used for the diagnosis of the infection were those of the CDC of Atlanta. RESULTS: A total of 200 patients were included in the study. Twenty one patients developed IAS that is a frequency of 10.5%. There were 11 men and 10 women with a mean age of 37.7 years with a standard deviation of 17.6 years. Surgical site infection was the most common HCAI (77.3%) followed by urinary tract infection (13.6%) and burn infection (9.1%). The influencing factors were those related to the patients (nutritional status p = 0.004, anemia RR = 3.1 IC p = 0.003 and diabetes), those related to the surgical intervention (the duration of the intervention ≥ 2H, p = 0,0001, the Altemeier class 3 and 4, RR = 4.24, IC p = 0.005, the number of interveners in the blocks ≥7, p = 0.000, the NNISS score 1 and 2 p = 0.0009), invasive procedures (bladder catheter ≥ 4 days p = 0.0000). Escherichia coli was the most isolated microorganism (31.2%) followed by Klebsiella pneumonia and A baumannii (18.7%). The treatment was local (twice-daily dressing with antiseptics), surgical (necrosectomy 16% and re-intervention 10%) and general (adapted to the antibiogram). The consequences of HCAI were an extension of total hospital stay (greater than 7 days) with p = 0.0000, morbidity 3% and mortality 5%. CONCLUSION: HCAI remains a concern in our country and globally. They prolong the hospital stay. The implementation of a prevention, control and surveillance program will improve the quality of care by significantly reducing HCAI.

Une infection est dite associée aux soins (IAS) si elle survient au cours ou au décours d'une prise en charge. L'OBJECTIF ÉTAIT: d'étudier les infections associées aux soins en chirurgie générale du CHU Gabriel Touré. MÉTHODOLOGIE: Il s'agissait d'une étude prospective de 6mois (d'avril à septembre 2016) intéressant les malades hospitalisés dans le service de chirurgie générale opérés ou non, sauf ceux ayant subi une nécrosectomie. Les critères utilisés pour le diagnostic de l'infection ont été ceux du CDC d'Atlanta. RÉSULTATS: Au total 200 malades ont été inclus dans l'étude. Vingt un patients ont développé des IAS soit une fréquence de 10,5%. Il s'agissait de 11 hommes et 10 femmes ayant un âge moyen de 37,7 ans avec un écart type de 17,6 ans. L'infection du site opératoire a été la plus fréquente des IAS (77,3%) suivie par l'infection urinaire (13,6%) et l'infection des brûlures (9,1%). Les facteurs influençant ont été ceux liés aux malades (état nutritionnel p=0,004 ; anémie RR=3,1 IC p=0,003 et diabète), ceux liés à l'intervention chirurgicale (la durée de l'intervention sup ≥2H p=0,0001 ; la classe d'Altemeier 3 et 4 ; RR=4,24 ; IC p=0,005 ; le nombre d'intervenants au blocs ≥7 ; p=0,000 ; le score de NNISS 1et 2 p=0,0009), les actes invasifs (sondage vésical ≥ 4 jours p=0,0000). Escherichia coli a été le germe le plus isolé parmi les micro-organismes (31,2%) suivi de Klebsiella pneumonia et A baumannii (18,7%). Le Traitement a été local (pansement biquotidien avec des antiseptiques), chirurgical (nécrosectomie 16% et ré-intervention 10%) et général (adapté à l'antibiogramme). Les conséquences des IAS ont été le prolongement de la durée totale d'hospitalisation (supérieur à 7 jours) avec p= 0,0000, la morbidité 3% et la mortalité 5%. CONCLUSION: Les IAS demeurent préoccupantes dans notre pays comme à l'échelle mondiale. Elles prolongent le séjour hospitalier. La mise en œuvre d'un programme de prévention, de contrôle et de surveillance permettra d'améliorer la qualité des soins en réduisant considérablement les IAS.
