[Health-care related infections in pediatric surgery of the teaching hospital Gabriel Toure, Bamako, Mali]. / Infections associees aux soins en chirurgie pediatrique au CHU Gabriel Toure, Bamako, Mali.

OBJECTIVES: to identify the main causative agents of infection associated with care and their susceptibility to antibiotics used and to identify risk factors for care-associated infection. MATERIAL AND METHODS: This was a cross-sectional study with prospective data collection, conducted from 1 November 2016 to 1 April 2017 among all children admitted to the pediatric surgery department. Non-consenting parents and cases of necrosectomy were included in this study. RESULTS: Our study involved 200 patients, 30 of whom presented a care-associated infection (15% infection rate). The average age of patients with infection was 56.33 ± 48.66 months (1 and 180 months). The main pathogens responsible for infection of the operative site were: Escherischia coli (4 cases), Acinetobacterbaumanii (3 cases), Klebsiella pneumoniae (2 cases), Staphylococcus aureus (2 cases), Enterobacter cloacae (1case), Pseudomonas aeruginosa (1 case) and Enterobacter faecalis (1 case). In the burned patients, the organisms found were: Acinetobacter baumanii (7 cases), Klebsiella pneumoniae (6 cases), Staphylococcus aureus (6 cases), Escherischia coli (4 cases), Pseudomonas aeruginosa (2 cases) and Enterobacter faecalis (2 cases). Escherichia coli was noted in urinary tract infection. Antibiotics tested were amoxicillin, amoxicillin-clavulanic acid, ceftriaxone, imipenem, gentamicin and ciprofloxacin. The mode of recruitment and the duration of hospitalization were the risk factors noted. CONCLUSION: The infection associated with care is a frequent occurrence in our practice. These infections mainly occur at the operating sites. The germs found were: Acinetobacter, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus. They are all sensitive to imipenem and resistant to amoxicillin. The infection remains formidable in health care. It is essential to give special attention to the prevention of infectious risk, especially in the surgical setting.

[Surgical site infections at surgery service B of Point "G" hospital]. / Infections du site operatoire en chirurgie « B ¼ CHU du Point G.

BACKGROUND: Surgical site infections (SSI) complicate most operations in developing countries. A variety of germs is responsible for it. The purpose of this study was to determine the incidence of surgical site infections and the bacteriological profile. PATIENTS AND METHODS: We conducted a prospective study for descriptive purposes. The included patients were treated between August 2016 and July 2017 in the Surgery B department of the University Hospital Center Point G. The study population consisted of all patients operated on and hospitalized for at least 72 hours. Patients who had an infection of the operative site were retained. The incidence of ISOs, the different bacterial strains and their susceptibility to antibiotics were studied. Data was analyzed on SPSS 12.0. RESULTS: The incidence of surgical site infections was 4.7%. The median age of the patients was 29.5 ± 4.34, the sex ratio was 1.66. The average time to onset of infections was 7.33 days. Of the samples taken, 4 bacterial strains were identified: Escherichia coli, Staphylococcus aureus, Acinobacter baumanii and Enterobacter spp. Isolated strains of Escherichia coli and Staphylococcus aureus were sensitive to Cefotaxim, Amikacin, Nitrofurantoin, but resistant to Ceftriaxon, Amoxicillin + Clavulanic acid. The species of Acinobacter baumanii and Enterococcus spp. Were sensitive to Colistin, but resistant to Ceftriaxone, Amoxicillin + clavulanic acid. CONCLUSION: Escherichia coli and Staphylococcus aureus are the main germs of the generally antibiotic-resistant ISOs commonly used in the service.

INTRODUCTION: Les infections du site opératoire (ISO) compliquent la plupart des opérations dans les pays en développement. Une diversité de germes en est responsable. Le but de cette étude était de déterminer l'incidence des infections du site opératoire et leur profil bactériologique. PATIENTS ET MÉTHODES: Nous avons réalisé une étude prospective à visée descriptive. Les patients inclus étaient pris en charge entre Aout 2016 et Juillet 2017 dans le service de chirurgie B du centre hospitalier universitaire du Point G. La population d'étude était constituée de tous les patients opérés et hospitalisés pendant au moins 72 heures. Les patients ayant présenté une infection du site opératoire étaient retenus. L'incidence des ISO, les différentes souches bactériennes et leur sensibilité aux antibiotiques ont été étudiées. Les données ont été analysées sur SPSS 12.0. RÉSULTATS: L'incidence des infections du site opératoire était de 4,7%. L'âge médian des patients était de 29,5 ans ±4,34, le sex ratio de 1,66. Le délai moyen d'apparition des infections était de 7,33 jours. Sur les prélèvements réalisés, 4 souches bactériennes étaient identifiées : Escherichia coli, Staphylococcus aureus, Acinobacter baumanii et Enterobacter spp. Les souches d'Escherichia coli et de Staphylococcus aureus isolées étaient sensibles au Cefotaxime, à Amikacine, à Nitrofurantoïne, mais résistantes à Ceftriaxone, à Amoxicilline+Acide clavulanique. Les espèces d'Acinobacter baumanii et d'Entérocoque spp étaient sensibles à Colistine, mais résistantes à Ceftriaxone, à Amoxicilline+Acide clavulanique. CONCLUSION: Escherichia coli et Staphylococcus aureus sont les principaux germes des ISO généralement résistants aux antibiotiques couramment utilisés dans le service.

[Bacteriology of acute exacerbations of chronic obstructive pulmonary disease in Tunisia]. / Bactériologie des exacerbations aiguës des bronchopneumopathies chroniques obstructives en Tunisie.

INTRODUCTION: The role of bacteria, including atypical organisms, in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) has been assessed in various ways in Tunisia. METHODS: This was a descriptive and analytical study of patients with a mean age of 68.3±10.5 years hospitalized for AECOPD. Bacteriological examination included a cytological sputum exam and serology for atypical organisms including Mycoplasma pneumoniae, Coxiella burnetii, Chlamydophila pneumoniae and Legionella pneumophila using standard techniques. RESULTS: Of the 240 patients enrolled, 175 sputum cultures (73%) were considered significant. Twenty-nine cultures were positive (16.5%) and 31 microorganisms were isolated of which the most frequent were P. aeruginosa (25.8%), K. pneumoniae (16.2%), H. influenzae (13%) and S. pneumoniae (9.7%). The prevalence of C. pneumoniae, M. pneumoniae and C. burnetii was 8.4%, 9% and 6.6%, respectively. No L. pneumophila infection was found. The Anthonisen criteria were associated with a positive culture (P=0.04). Almost half (40.9%) of the isolates were resistant to conventional first line antibiotics (43.7% to amoxicillin-clavulanic acid). CONCLUSIONS: Awareness of the low positivity of quantitative sputum bacteriology and the large percentage of resistant strains with a predominance of exclusively multi-resistant Pseudomonas should help in the management of patients with AECOPD.

Política de prevenção da disseminação de germes multirresistentes no Hospital de Clínicas de Porto Alegre / Policy for prevention of transmission of multidrug-resistant organisms at Hospital de Clínicas de Porto Alegre

O aumento da incidência de germes multirresistentes (GMR) e a falta de opções terapêuticas a curto ou médio prazo representam um grande desafio aos hospitais no que se refere à prevenção da disseminação destas bactérias. Para a prevenção da transmissão de agentes infecciosos no ambiente hospitalar é preconizada a adoção de medidas de bloqueio epidemiológico. Essas políticas de bloqueio devem estar claramente estabelecidas, divulgadas aos profissionais de saúde e adotadas por estes a fim de minimizar a incidência de GMR. Revisamos aqui a política de prevenção da disseminação de germes multirresistentes no Hospital de Clínicas de Porto Alegre.

The increasing incidence of multidrug-resistant organisms (MDROs) and the lack of therapeutic options in the short and medium term pose a major challenge to hospitals with regard to preventing the spread of these bacteria. Infection control measures are recommended to prevent transmission of infectious agents in hospital settings. These infection control policies should be clearly established and disseminated among health professionals in order to minimize the incidence of MDROs. We reviewed a hospital policy for prevention of transmission of MDROs at Hospital de Clínicas de Porto Alegre, southern Brazil.
