[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.

Fluorescein diacetate and rapid molecular testing for the early identification of rifampicin resistance in Mali.

BACKGROUND: Non-conversion on auramine smear microscopy indicates a lack of treatment response, possibly associated with initial rifampicin-resistant tuberculosis (RR-TB). However, dead bacteria still stain positive and may be detected. Fluorescein diacetate smear microscopy (FDA) shows live mycobacteria only. Therefore, we studied the potential of 2-month (2M) FDA for the identification of initial RR-TB.METHODS: Between 2015 and 2018, we enrolled new smear-positive pulmonary TB patients from five local centres in Bamako, Mali. After baseline screening, sputum samples were collected at 1M, 2M, 5M and 18M. We used rpoB sequencing to identify initial RR-TB.RESULTS: Of 1359 patients enrolled, 1019 (75%) had rpoB sequencing results. Twenty-six (2.6%, 95%CI: 1.7-3.7) had mutations conferring rifampicin resistance. Most frequent rpoB mutations were located at the codons Asp435Val (42.4%) and Ser450Leu (34.7%). Among patients with initial RR-TB, 72.2% were FDA-negative at 2M (P = 0.2). The positive and negative predictive value of 5M FDA for culture-based failure was respectively 20.0% and 94.7%.CONCLUSION: FDA did not identify the majority of patients with initial RR-TB or culture-based failure. As the full spectrum of mutations identified on sequencing was identified using Xpert, our data support its rapid universal implementation in Mali.

[Epidemiological And Clinical Aspects Of Obesity In The Medicine And Endocrinology Service Of Mali Hospital]. / Aspects Epidemiologique Et Clinique De L'Obesite Dans Le Service De Medecine Et D'Endocrinologie De L'Hopital Du Mali.

INTRODUCTION: Lifestyle changes have played an important role in increasing the prevalence of obesity. The objectives were to describe the epidemiological, clinical and progressive aspects of obesity in patients of the Mali hospital. PATIENTS AND METHOD: this is a descriptive study with retrospective collection of data from the medical records of patients hospitalized in the Medicine and Endocrinology department. Our patients benefited from weight gain, height, waist measurement and hip measurement with calculation of the body mass index. RESULTS: the study concerned 90 obese patients out of 1515 hospitalized (5.94% of frequency). The mean age was 42 ± 5 with extremes 10 and 74. The sex ratio was 0.38. Obesity was mixed: 75.4% of men, 60% of woman; Android in 36% of men, 18% of women and the only child aged 10 had morbid obesity. The reason for hospitalization was complications of obesity in 13.30%. The psychological reactions collected were: anxiety 54.40%, indifference 40% and shame 5.60%. There were 68.90% complications including 37.80% cardio metabolic (hypertension associated in 51.10%). The lipid assessment carried out showed hyper LDLdemia: 70%; HDL hypoemia: 67.80%, hyper triglyceridaemia: 66.70%. Our patients received dietary and dietary advice. No drug or surgical treatment has been initiated despite the indication. We recorded 3.30% of deaths. CONCLUSION: The epidemiological and clinical description, diagnosis and evaluation of the repercussions of obesity are easy in our daily practice. However, care remains insufficient due to the inadequacy of the technical platform, the lack of financial means and the prejudices of our patients (ignorance of obesity as a disease).

INTRODUCTION: Le changement du mode de vie a joué un rôle important dans l'augmentation de la prévalence de l'obésité. Les objectifs étaient de décrire les aspects épidémiologiques, cliniques et évolutifs de l'obésité chez les patients de l'hôpital du Mali. PATIENTS ET MÉTHODE: il s'agit d'une étude descriptive avec recueil rétrospectif des données à partir des dossiers médicaux des patients hospitalisés dans le service de Médecine et d'Endocrinologie. Nos patients ont bénéficié d'une prise de poids, de la taille, du tour de taille et du tour de hanche avec calcul de l'indice de masse corporelle. RÉSULTATS: l'étude a concerné 90 patients obèses sur 1515 hospitalisés (5.94% de fréquence). L'âge moyen était 42 ans ± 5 avec des extrêmes 10 et 74 ans. Le sex - ratio était de 0,38. L'obésité était de type mixte : 75.4% des hommes, 60% de femme ; androïde chez 36% des hommes, 18% de femme et la seule enfant âgée de 10 ans avait une obésité morbide. Le motif d'hospitalisation était les complications de l'obésité dans 13,30 %. Les réactions psychologiques recueillies étaient : l'inquiétude 54.40%, l'indifférence 40% et la honte 5.60%. Il y avait 68.90% de complications dont 37.80% cardio métaboliques (HTA associée dans 51.10%). Le bilan lipidique réalisé montrait une hyper LDLdémie : 70% ; une hypo HDLdémie : 67.80%, une hyper triglycéridémie : 66.70%. Nos patients ont reçu des conseils hygiéno-diététiques. Aucun traitement médicamenteux, ni chirurgical n'as été instauré malgré l'indication. Nous avons enregistré 3.30% de décès. CONCLUSION: La description épidémio-clinique, le diagnostic et l'évaluation du retentissement de l'obésité sont faciles dans notre pratique quotidienne. Cependant la prise en charge reste insuffisante du fait de l'insuffisance du plateau technique, le manque de moyen financier et les préjugés de nos patients (méconnaissance de l'obésité comme une maladie).

Diabetes Mellitus among new tuberculosis patients in Bamako, Mali.

INTRODUCTION: Diabetes Mellitus (DM) increases worldwide, mostly in low- and middle-income countries. In Mali, the prevalence in the adult population is estimated at 1.8%, but tuberculosis (TB) patients are not systematically screened. The goal of our study was to determine the prevalence of DM among newly diagnosed TB patients. METHODS: We conducted a cross sectional study and a pilot prospective cohort study in four health centers in Bamako. All patients underwent fasting capillary-blood glucose (FCBG) test at Day 0, and repeated after one-week of TB treatment. Venous FBG test was performed for discrepancies between the two FCBG results. Thereafter, FCBG was performed for pilot study at month-2 (M2) and M5 of TB treatment. RESULTS: Two hundred and one patients were enrolled in this study. Impaired fasting blood glucose was identified in 17 (8.5%), of whom 11 (5.5%) had DM (VFBG >7 mmol/L). Among patients with DM, seven (63.6%) had successful TB treatment outcome, versus 142 (74.7%) of those without DM (p = 0.64), and (OR: 1.69, 95%CI 0.47-6.02). CONCLUSION: The prevalence of DM among TB patients in Bamako exceeds that of the general population and screening at TB diagnosis suffices to identify those with DM. Systematic screening of both diseases will allow better treatment.

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.

Prevalence of extended-spectrum beta-lactamase phenotypes in enterobacteria isolated from blood cultures of patients at admission to the University Hospital of Bamako.

The aim of our study was to determine the frequency of extended-spectrum beta-lactamase (ESBL) phenotypes among the enterobacteria present in blood cultures of patients at admission to two university hospitals of Bamako (Mali). During a period of three months, we isolated enterobacteria from blood cultures from patients upon admission to the Point G and Gabriel Toure University Hospitals. The ESBL-positive enterobacteria were initially identified by API 20E strips and VITEK®2 and then confirmed in France by MALDI-TOF mass spectrometry at the Bichat Hospital bacteriology laboratory. Antibiotic susceptibility was determined by the diffusion method as recommended by EUCAST. The species isolated were K. pneumoniae (14/40, 35.0 %), E. coli (11/40, 27.5 %), and E. cloacae (9/40, 22.5 %); 21/34 (61.8 %) had an ESBL phenotype, including 10/14 (71.4 %) K. pneumoniae, 8/11 (72.7 %) E. coli, and 3/9 (33 3 %), E. cloacae. The ESBL strains of K. pneumoniae, E. coli, and E. cloacae were associated, respectively, with resistance to the following antibiotics: gentamicin (10/10, 100 %; 6/8, 75%; 2/3, 67%), amikacin (2/10, 20 %; 0/8, 0%; 0/3, 0%), ofloxacin (8/10, 80. %; 7/8, 87%; 3/3, 100%), cotrimoxazole (10/10, 100 %; 6/8, 75%; 3/3, 100%). Almost two thirds (61.8%) of the enterobacteria isolated from blood cultures produced extended-spectrum beta-lactamases. They retained regular sensitivity only to carbapenems and amikacin.

[High prevalence of methicillin-resistant Staphylococcus aureus strains in the Point G teaching hospital in Bamako, Mali]. / Haute prevalence des souches de staphylococcus aureus resistantes a la meticilline au centre hospitalier universitaire du Point G a Bamako (Mali).

Our aim was to study the susceptibility of Staphylococcus aureus to antimicrobial agents and to determine the methicillin-resistant S. aureus (MRSA) prevalence in the Point G teaching hospital in Bamako. METHODS: Columbia blood agar with nalidixic acid and colistin was used for the isolation of S. aureus strains. The diffusion method was used for antimicrobial susceptibility testing. RESULTS: Of 434 non repetitive strains of S. aureus isolated from 2007 to 2009 in the Point G teaching hospital, 297 (68.6%) were from hospital area and 137 (31.4%) were from extra-hospital area. The hospital strains were more resistant to penicillin than the extra-hospital strains (95% versus 88%; p = 0,016). Tetracycline was more active against hospital clinical isolates than extra-hospital clinical isolates (32% versus 21%; p = 0.024). Among 297 S. aureus clinical isolates, 195 (66%) were MRSA and 102 (34%) were methicillin-susceptible S. aureus (MSSA). The MRSA clinical isolates prevalence was higher in hospital area than in extra-hospital area (66% versus 55.5%; p = 0.0418). The MRSA clinical isolates prevalence was higher in the medical wards than in the surgical wards (74.8% vs 34.3%; p < 10-6). Among 251 MRSA clinical isolates, 169 (67.3%) were from urine, 39 (15.5%) from pus, 30 (12%) from blood culture, 7 (2.9%) from vagina and 6 (2.5%) from other sites. The MRSA clinical isolates prevalence was 46% in 2007, 63% in 2008 and 80% in 2009. The MRSA clinical isolates were highly more resistant to penicillin (p < 10-6), to amoxicillin combined with clavulanic acid (p < 10-6), to aminoglycosides (p < 10-6), to macrolides, lincosamides and streptogramins (p < 10-6), to norfloxacin (p < 10-6), to chloramphenicol (p < 10-6), to tetracycline (p = 0,0042), to sulfonamides (p < 10-6), to trimethoprim (p < 10-6), to fusidic acid (p < 10-6), and to fosfomycin (p = 0,0103) than the MSSA strains. The high level resistance to aminoglycosides, fluoroquinolones, macrolides, lincosamides and streptogramins was more frequent in the MRSA strains than in the MSSA strains. CONCLUSION: The MRSA clinical isolates prevalence was very high in the Point G teaching hospital in Bamako, in the medical wards especially. The MRSA strains were drugs multiple resistant.

Notre objectif était d'étudier la sensibilité de Staphylococccus aureus aux antibiotiques et de déterminer la prévalence des souches résistantes à la méticilline au centre hospitalier universitaire du Point G à Bamako. MÉTHODES: L'isolement des souches de S. aureus a été réalisé sur la gélose Columbia additionnée de sang de mouton, d'acide nalidixique et de colistine. L'étude de la sensibilité aux antibiotiques a été faite par la méthode des disques. RÉSULTATS: Sur 434 souches non répétitives de S. aureus isolées de 2007 à 2009 au centre hospitalier universitaire du Point G, 297 (68,6 %) sont d'origine hospitalière et 137 (31,4 %) d'origine extrahospitalière. Les souches hospitalières ont été plus résistantes à la pénicilline G que les souches extrahospitalières (95 % versus 88 %; p = 0,016). La résistance de S. aureus à la méticilline (SARM) a été plus fréquente chez les souches hospitalières que chez les souches extrahospitalières (66 % versus 55,5 %; p = 0,0418). Les plus hautes prévalences de SARM ont été observées dans les services de néphrologie (90 %), de cardiologie (87,5 %) de médecine interne (71 %), d'hématologie-oncologie médicale (66 %) et des maladies infectieuses (65 %). La prévalence des souches de SARM a été de 46 % en 2007, 63 % en 2008 et 80 % en 2009 en milieu hospitalier. Les souches de SARM ont été plus résistantes à la pénicilline G (p < 10−6), à l'association amoxicilline + acide clavulanique (p < 10−6), aux aminosides (p < 10−6), aux macrolides, lincosamides et streptogramines (p < 10−6), à la norfloxacine (p < 10−6), au chloramphénicol (p < 10−6), à la tétracycline (p = 0,0042), aux sulfamides (p < 10−6), au triméthoprime (p < 10−6), à l'acide fusidique (p < 10−6), et à la fosfomycine (p = 0,0103) que les souches de S. aureus sensibles à la méticilline (SASM). Les phénotypes de résistance aux aminosides (KTG, S+ KTG) et aux macrolides, lincosamides et streptogramines (MLSB constitutif) ont été plus fréquents chez les souches de SARM que chez celles de SASM. CONCLUSION: La prévalence des souches de SARM a été très élevée au centre hospitalier universitaire du Point G, dans les services de médecine surtout. Les souches de SARM sont multirésistantes.

[Necrotizing cervico-facial cellulitis of dental origin in a developing country]. / Les cellulites cervico-faciales nécrosantes d'origine dentaire dans un pays en voie de développement.

INTRODUCTION: Necrotizing cellulitis of dental origin is a serious disease and requires prompt and effective management to avoid adverse outcomes. The purpose of this work is to describe the diagnostic and therapeutic difficulties encountered in this condition. METHODS: This was a prospective study in the thoracic surgery department of Mali Hospital from January 2011 to February 2015. We collected consecutively 19 cases of complicating cervico-facial cellulitis of dental origin. The anatomical and clinical aspects, therapeutic modalities and difficulties are described. RESULTS: Dental pain and fever were the predominant symptoms followed by cervical edema. Chest CT-scan was the basis for the diagnosis in all cases. Cervicotomy with debridement was the most performed surgical procedure. Pleural drainage was performed in 6 cases. Three patients (15.8%) died. CONCLUSION: Necrotizing cellulitis of dental origin is a serious disease with high morbidity and mortality. The key radiological examination is the thoracic CT-scan. Early medico-surgical management by emergency care, tailored antibiotic therapy, removal of necrotizing tissues and drainage of collections are required to deliver a good outcome.

Prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae isolated from blood cultures in Africa.

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

[Alpha interferon induced hyperthyroidism: a case report and review of the literature]. / LE CAS CLINIQUE DU MOIS. Hyperthyroïdie induite par interféron alpha: rapport d'un cas et revue de la literature.

Treatment with alpha interferon in hepatitis C triggers a thyroid autoimmunity in a variable percentage of cases (2-8%). This complication raises some questions about its screening, the possibility to continue anti-viral therapy and thyroid treatment. Alpha interferon has an immunomodulatory effect on the thyroid, but also an inhibitory effect on thyroid hormone synthesis. This explains the occurrence of cases of thyroid dysfunction, which often remain undetected because of their latency. Factors predicting thyroid dysfunction with interferon use are: female sex, history of thyroid disease and previous autoimmunity. Several clinical aspects are encountered including hypothyroidism (the most frequent depending on the series) and hyperthyroidism related to Graves' disease. For their detection, a cooperation between general practionners, gastroenterologists and endocrinologists is mandatory thyroid function tests are requested before, during and after treatment,with alpha interferon. Therapeutic aspects of thyroid disorders range from simple monitoring to symptomatic treatment, such as thyroxine prescription in the presence of hypothyroidism. Antithyroid drugs radioactive iodine or thyroid surgery are used in cases of severe or persistent Graves' disease induced by alpha interferon.

[Heller myotomy by transthoracic procedure, a single center experience in Mali with 21 cases]. / Myotomie de heller par voie transthoracique : une experience monocentrique au mali de 21 cas.

AIMS: To evaluate the midterm results of myotomy for achalasia by thoracotomy procedure with the introduction of anti-reflux system by diaphragmatic flap. PATIENTS AND METHODS: This was a prospective study involved 21 patients (14 women and 7 men) operated for idiopathic megaesophagus during a period of 3 years. All the patients were operated by thoracotomy procedure. An anti-reflux system was performed using a diaphragmatic flap over the entire length of the myotomy. RESULTS: The mean age was 32 years (range 16 and 68 years). After the surgery we have seen a complete disappearance of dysphagia in 21 patients (100 %) (p <0.001) and a significant weight regain. Short term outcomes were marked by the occurrence of clinical gastroesophageal reflux disease in 1 patient (4.76%) who has received the anti-reflux system (p> 0.05). CONCLUSION: Oeso-cardio-myotomy of Heller by transthoracic procedure associated with the establishment of an anti reflux system by diaphragmatic flap has goods results.

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.

[Neuromeningeal cryptococcosis in Mali]. / La cryptococcose neuro-méningée au Mali.

Cryptococcal meningitis is the most common fatal central nervous system infection in AIDS patients in Sub-Saharan Africa. The purpose of this prospective study conducted from March 2003 to February 2004 in the internal medicine and infectious diseases departments of the Point G University Hospital Center was to investigate the clinical, prognostic and epidemiological profile of Cryptococcus neoformans infection in patients hospitalized for brain and meningeale infection (BMI). Diagnosis of neuromeningeal cryptococcosis (NMC) was based on positive identification of Cryptococcus by direct exam of the cebrospinal fluid (CSF) after India ink staining and/or culture on Sabouraud medium without actidione. During the study period, a total of 569 patients were hospitalized including 235 (41.3%) with HIV infection. Overall C. neoformans was identified in 14 patients. Median patient age was 39 +/- 8 years. There was a male preponderance with a sex ratio of 1.8 (9 men/5 women). Patients with BMI were HIV-positive in 85.7% of cases (n=12) and HIV-negative in 14.3% (n=2). The overall and HIV-specific prevalence of BMI was 2.5% and 5.1% respectively. The CD4 lymphocyte count was between I and 49 cells/mm3 in 64.3% of cases. The main clinical symptoms were cephalea in 85.7% of cases, altered consciousness in 50% and nausea/vomiting in 35.7%. Neurological manifestations (hemiparesis and cranial nerve deficit) were noted in 14.3%. HIV infection is the main purveyor of NMC in Mali. The actual incidence of cryptococcosis is unclear due to the poor sensitivity of diagnostic techniques. This study highlights diagnostic difficulties related to clinical polymorphism and poor technical facilities. Agglutination testing of blood and CSF is recommended, but mortality remains.

[Tetanus in a hospital setting in Bamako, Mali]. / Tétanos en milieu hospitalier à Bamako, Mali.

AIM: The purpose of this study was to describe the epidemiological, clinical, and prognostic profile of tetanus patients managed in the infectious diseases department of the "Hopital du Point G", in Bamako, Mall. PATIENTS AND METHODS: This retrospective descriptive study was conducted from July 2001 to August 2004. The following data were collected: age, sex, infection route, clinical features, delay to hospitalization, and outcome. RESULTS: A total of 54 patients hospitalized for tetanus were included. Men accounted for 68.5% of cases. Ages ranged from 15 to 66 years with a mean of 39 years. The most common professional activity was farming: 27.8%. The route of infection was determined in 87% of cases and involved cuts in 46.3% of cases located on the lower limbs in 42.6%. Generalized paroxystic tetanus with opisthotonos was the most prevalent form accounting for 18.5% of cases. Localized tetanus accounted for 12.9% of cases. Outcome was unfavorable with a death rate of 38.9%. All deaths occurred within the first week of hospitalization. CONCLUSION: Mass vaccination of the population should be a national priority to reduce tetanus-related morbidity and mortality to levels observed in industrialized countries.

Tétanos en milieu hospitalier à Bamako, Mali

RÉSUMÉ â€¢ Objectif. Le but de cette étude était de décrire le profil épidémiologique, clinique et évolutif du tétanos au service des maladies infectieuses de l'hôpital du Point G de Bamako au Mali. Malades et méthodes. Il s'agissait d'une étude rétrospective descriptive de juillet 2001 à août 2004. Ont été recueillis : l'âge, le sexe, la porte d'entrée, les signes cliniques, le délai d'hospitalisation ainsi que l'évolution. Résultats. Cinquante quatre patients hospitalisés pour tétanos ont été inclus. Le sexe masculin était le plus représenté avec 68,5% des cas. Les patients étaient âgés de 15 à 66 ans avec une moyenne d'âge de 39 ans. La profession paysanne dominait avec 27,8%. La porte d'entrée était présente dans 87% des cas. Sa nature était une plaie dans 46,3%,siégeant aux membresinférieurs dans 42,6%. Le tétanos généralisé paroxystique avec attitude en opisthotonos était le plusfréquent avec 18,5%, et le tétanoslocalisé avec 12,9% des cas. Le pronostic a été mauvais avec une létalité de 38,9%. Tous les décès étaient survenus pendant la première semaine d'hospitalisation. Conclusion. Pour réduire la morbidité et la mortalité liées au tétanos à l'image des pays développés, la vaccination de masse devrait être une priorité nationale au Mali

[Neuromeningeal cryptococcosis in non-HIV patients to CHU ward of Point G in Bamako (Mali): 3 case report]. / Cryptococcose neuroméningée chez des patients VIH négatif au CHU du Point G de Bamako (Mali): à propos de trois observations cliniques.

We report 3 clinical observations of neuromeningeal cryptococcosis which occurred without any immunodepression related to HIV infection. Our patients were male. They did not present any particular medical history indicating a diagnosis of cryptococcosis. Nevertheless we found a professional exposure to the risk of inhalation of C. neoformans capsules. The diagnosis was based on presence of encapsulated yeast of Cryptococcus in the direct exam by China ink and culture on Sabouraud medium. CD4 lymphocytic count was done in two patients (case 1:899 cells/mm3; case 2:347 cells/mm3). Idiopathic lymphocytopenia was noted in one case. Co-morbidity of 5. pneumoniae meningitis was reported in one patient (case 3). Treatment was based on injectable amphotericin B in monotherapy (case 1), followed by perfusion of fluconazole cure (case 2). Case 3 was treated by perfusion of amphotericin B associated with ceftriaxone (case 2). No secondary prophylactic treatment was administered. Evolution was favorable after follow-up of 5 years (case 1) and of 4 years (case 2). The third patient died during hospitalization.

[Factors affecting nosocomial infection in the surgery setting at the Hospital of Point "G"]. / Facteurs influencant l'infection nosocomiale en milieu chirurgical à l'Hôpital du Point "G".

Nosocomial infections are a common and increasing problem globally, and particularly in Africa. The significant economic burden of these infections on the health care system as well as their impact on patient morbidity and mortality is well recognised within the medical communities.The goal of this study was to investigate factors that influence nosocomial infection in all in-patients from the surgery wards (surgery ward A and B, Gynoeco-obstetrics, urology and intensive care) at the national hospital of Point G in Bamako, Mali. We report the number of nosocomial infection during a prospective study between June 2003 and January 2004. Of 1043 in-patients, 102 had had a nosocomial infection with a global prevalence of 9.7% (8.0-11.4). Of 1024 patients with surgery, 101 had had a nosocomial infection, a post-surgery nosocomial infection rate of 9.8% (8.1-11.5). We observed different site of nosocomial infection such as suppuration sup-aponevrotics (41.2%), parietal infection sub-aponevrotics (32.4%), urinary infection (17.6%) and organ suppuration (3.9%). Other nosocomial infection observed were pneumonia (2.9%) and catheterisation (2.0%). The nosocomial infection rate was 10.3% in male while it was 7.3% in female. The difference between male and female was not statistically significative (chi2 = 2.33, p = 0.12). Nosocomial infection was more prevalent in patients after emergency surgery (15.1%) than in scheduled surgery patients (8.5%) (chi2 = 8.15, p = 0.004). The classes III and IV of ALTEMEIER had the higher proportion of nosocomial infection (35.9%) against 4.8% for the classes I and II (chi2 = 144.95, p < 0.001). The patients with ASA score I had a lower nosocomial infection rate than patients from the intensive care unit or patients of Class II + III + IV (chi2 = 13.2, p = 0.001). Patients classified according to the National Nosocomial Infection Surveillance System (NNISS) with a score 0 had a nosocomial infection rate less than patients classified as NNISS score 1, 2 or 3 (chi2 = 82.0, p < 0.001). The study results underline the need for further investigations of the role of microbial agents and antimicrobial resistance in the outcome of patients with nosocomial infection.

[Association of urinary tract infections and HIV infection in an internal medicine ward of Hospital of Point G-Bamako-Mali]. / L'association infection urinairie st infection VIH a dans le service de medicine interne de l'Hopital du Point G-Bamako-Mali.

We gathered 14 clinical observations of urinary track infections in AIDS patients in Internal Medicine wards from August 1, 1998 to July 31, 1999. Urinary track infection and HIV were both present in 1.75% of 797 hospitalized patients. The specific prevalence was 14.43% among AIDS patients. The sex ratio (female/male) was 1.33. The mean age of patients was 37.2 years with ranges between 25 years and 59 years. Urinary symptoms were discret. Urinary tract infection was primarily evidenced by urine leucocytes > 10(4) organism/ml and a bacteriuria > 10(5) colony-forming units/ml. The main pathogenswere Escherichia coli (42.85%), Klebsiella pneumoniae (28.57%), Colibacilles app. (21.42%) and Enterobacter cloacae (7.14%). All isolated germs were sensible to the gentamicin, to the amikacin, to the nalidixic acid, to the cefoxitine, to the ceftazidime to the cefotaxime and the ciprofloxacin. Cephalosporin of 3rd generation, aminoglycosides, and fluoroquinolone can be used like treatment of first line in urinary tract infection suspicion case in Bamako. Our patients were highly immunosuppressed with the majority of them being in class IV C of CDC of Atlanta (90%) and CD4 count constantly bellow 200 cells/mm3. The main opportunistic affections were non bacilar bacterial pneumopathies (28.57%), oesophagal mycosis (71.42%), the association of cerebral toxoplasmosis and pulmonary tuberculosis (35.71%). All urinary infections were cured by mean of 5 days of treatment. Very few recidivism was found (1 case).

[The etiological, clinical and prognosis of diarrhea occurs during AIDS in to hospital in Bamako]. / Aspects sémiologique, étiologique et pronostique de la diarrhée au cours du SIDA en milieu hospitalier de Bamako.

UNLABELLED: Its was a descriptive survey achieved in the service of the infectious and tropical illnesses of the teaching hospital of the "Point G" from 31 December 2002 to 30 June 2004 was about the analysis of 76 files. Its goal was to determine the clinical, etiological and prognostic aspects, of the diarrhea during the AIDS. The oral-pharyngeal candidiasis (50%), the deshydratation (60,5%), the fever (67,5%) and the thinning (77,6%) were associated to the diarrhoea frequently. Cholera syndrome was (52.6%), dysenteric syndrome was (36.8%) and the diarrhea syndrome was (10.5%). According to the etiological aspect, the parasites were founded in 51,3 % of cases, bacteria 9,2 % of cases, and fungus 5,3%. Any pathogen hasn't been founded in 34,2% of cases. Cyptosporidium parvum (15,8 %), and Isospora Belli (11,8%) was the most common parasites founded, but some unusual pathogens as: Entamoeba hystolitica, Trichomonas intestinalis , Giardia intestinalis , Shistosoma mansoni , Dicrococelium dendriticum, Trichostrongylus were present . The most common bacteria were Escherichia coli 5,3%. The fungus family was represented by Candida albicans . The lethality rate was 46,1%. CONCLUSION: The etiology of diarrhea occurs during aids is variable and include opportunistic and non opportunistic. The fatality rate remains incised because the delay of care and the poverty of the patients.
