Background: The emergence and spread of multidrug-resistant bacteria have become a major public health problem worldwide, particularly in developing countries such as Burkina Faso. This study aims to determine phenotypic and genotypic antibiotic resistant diarrheagenic Escherichia coli (DEC) from patients with diarrhea in Ouagadougou, Burkina Faso. Methodology: Microbiological and biochemical analysis were done to detect two hundred and ninety-two (292) strains. The susceptibility of the strains to antibiotics was determined by the agar disc diffusion method. 16-plex-PCR assays were carried out to detect both virulence and resistance genes encoding betalactams, quinolones, phenicols, tetracyclines and virulence gene of DEC. Results: Diarrheagenic Escherichia coli was detected in 8% (23/292) of patients with diarrhea using the 16-plex-PCR and 39.1% (9/23) of the DEC detected carry at least one resistance gene. Resistance rate in disc diffusion test was 86.96% to tetracycline, 65.23% to cotrimoxazole, 17.4% to nalidixic acid, 17.4% to norfloxacin, 17.4% to ciprofloxacin, 13.04% to ceftriaxone, 13.04% to cefotaxime, 8.7% to gentamicin, 8.7% to Chloramphenicol, 0% to netilmicin. The prevalence of different resistance genes in the studied strains varied from 44.4% to 5.5%. The gene Tet coding for resistance to tetracycline was found in 8 strains (44.4%). The CatA gene coding for resistance to Chloramphenicol was detected in 38.9% of isolates. The qnrS, blaSHV and blaOXA genes were each detected in 5.5% of isolates. No strain hosts the qnrA, qnrB and blaTEM genes. Conclusion: This study identified β-lactams, quinolones, phenicols and tetracyclines resistance genes in DEC isolates from patients with diarrhea in Ouagadougou, Burkina Faso. These results indicate the need for a surveillance program to reduce the prevalence of resistance to Enterobacteriaceae strains in hospitals.

Thoracic Aortic Aneurysm Revealed by Haemoptysis on a 10-Year-Old Girl at Paediatrics Department of Yalgado Ouedraogo University Hospital

Thoracic aortic aneurysm is a rather rare disorder in children and difficult to diagnose. It is generally linked to congenital heart defects or connective-tissue diseases. Our case is a 10-year-old girl admitted in the pediatric emergency care unit on January 19th, 2015 for massive haemoptysis and severe anaemia. Examination revealed severe anemia and a silent left lung. The Chest X-Ray revealed an abnormal mass on the upper left side of the mediastinum, and left lower lobe consolidation. The thoracic CT scan highlighted a 64 mm aneurysm of the subisthmic aorta with a thin 5 mm hole. It also showed pseudocoarctation of the aorta. Treatment in intensive care consisted of blood transfusion and iron supplement. She was due to travel abroad for cardio vascular surgery, but died on November 2016. Thoracic Aortic Aneurysm in our setting was discovered incidentally. In spite the fact that it is an extreme surgical emergency, in Burkina Faso, treatment can only be possible abroad upon medical evacuation.

The Destombes-Rosai-Dorfman Disease or Sinus Histiocytosis with Massive Lymphadenopathy: A Rare Case Described in the Paediatrics Department of Yalgado Ouedraogo University Hospital

Destombes-Rosai-Dorfman’ disease (DRD) is an inflammatory non-langerhansian histiocytosis with adenomegaly. It is a rare histiocytic disorder worldwide, less than 1000 reported cases. It is of unknown etiology and is characterized in its classical form by multiple adenomegalia, especially localized at cervical area, but also at mediastinal, axillary and inguinal areas. It is a benign condition, even if it is deforming, with spontaneously resolving evolution. We report a case of DRD disease in a 13-year-old girl, hospitalized in the Department of Pediatrics of the Yalgado Ouédraogo University Hospital Center in Ouagadougou, in March 2015. She was admitted for a voluminous bilateral painless cervical swelling, with no sign of local compression, having been operating for about a year. Biological tests showed signs of chronic inflammation;the imagery specified the benign character of these formations: adenomegalia. Confirmation of the diagnosis was made by pathological examination, describing the aspect of emperipolesis to histology and, immunohistochemistry, polytypic plasmacytosis and PS100 positive/CD1a histiocytosis negative. The treatment could not be properly carried out, in view of the early discharge, against medical advice from the patient. The evolution would have been marked, according to the parents, by a slight involution of swelling.
