[Neuro-Behçet in a Sub-Saharan Africa Country: a Series of Sixteen Patients in Fann Teaching Hospital, Dakar, Senegal]

Neuro-Behçet (NB) African studies are mainly North African, but Sub-Saharan Africa is not to be outdone. Our aim was to describe diagnostic and therapeutic features of NB in a Senegalese series collected in Dakar. This was a descriptive and retrospective study conducted at the Neurology department of Fann Teaching Hospital in Dakar, Senegal. All patients who met the NB's diagnostic criteria were included. Sixteen patients were collected, 14 males and 2 females with an average age of 40 years [18-71]. The main neurological signs were motor deficit (13 cases), headache (10 cases), and language disorders (4 cases). Extra-neurological signs were dermatological (14 cases), ocular (2 cases), and articular (2 cases) with aseptic unilateral gonarthritis. Fever was present in 9 patients. Neurological involvement was mostly isolated parenchymal (8 cases) or mixed (6 cases). The main clinical forms of NB were rhombencephalitis (8 cases) and retrobulbar optic neuritis (4 cases). Seven patients had a cerebral angio-Behçet with cerebral venous thrombosis (3 cases), ischemic stroke (2 cases), and intracerebral hematoma (2 cases). Under prednisone (16 cases) and azathioprine (3 cases), the short-term clinical outcome was mostly favorable (14 cases) with a modified Rankin scale at 2. NB is an under-diagnosed adult male disease in Sub-Saharan Africa and further studies are needed.

Molecular detection of CTX-M-15-type β-lactamases in Escherichia coli strains from Senegal

We aimed to detect the extended-spectrum β-lactamases (ESBLs) secreted by clinical strains of Escherichia coli at Fann University Hospital in Dakar and to characterize them molecularly. We identified 32 isolates producing ESBLs. The CTX-M-15 gene was the most frequently detected ESBL gene, detected in 90.63% of the isolates studied.

[RESAOLAB: West African network of laboratories to enhance the quality of clinical biology]

The Fondation Mérieux, in partnership with the Ministries of Health of Burkina Faso, Mali and Senegal, implemented for four years a project to reinforce the laboratory sector in the three participating countries: the RESAOLAB project (West African Network of Biomedical Analysis Laboratories).The objective of RESAOLAB project, in partnership with the WHO Office for West Africa and the West African Health Organization, was to strengthen the systems of biomedical laboratories to improve diagnostic services, access, monitoring and management of infectious diseases. Following the successful results achieved under the RESAOLAB project and due to the demand of the neighbour countries ministries, the RESAOLAB project is now extended to four other countries of the West African region: Benin, Guinea-Conakry, Niger and Togo. The RESAOLAB project has become the RESAOLAB programme, its purpose is to strengthen the quality of the medical biology services thanks to a regional and transversal approach.

[Hand washing at Fann hospital: investigation among health workers]

INTRODUCTION

Handwashing is usually neglected in hospital settings. The objective of this study was to draw attention of health workers in Fann hospital as part of the prevention of hospital-acquired infections.

MATERIALS AND METHODS

This study was carried out prospectively from April 26h to May 25th. An anonymous questionnaire was administered by 20 formed investigators to health workers, along with an inventory of available resources for hand washing in the study site allowing to collect the data by interview.

RESULTS

A total of 256 health workers were investigated. The mean age was 35.3 +/- 9.4 years [range = 20-71] with a sex ratio of 0.62. As for the education level, the secondary and university predominated. The concept of Manu carrying was ignored by 59.3% of the personnel. This proportion was higher among people with low education level. Possibility of resident and transitional floras in the hand was ignored by most of the investigated personnel. The hand washing technique to be applied while putting vesicle probe was ignored by 59% of the personnel, and 34% declared using hand towel to dry hands. Half of the personnel ignored that bread soap was not recommended. The availability of hydro alcoholic solutions was variable according to the hospital wards. The lavabo/bed ratio was 1/7 and was unacceptable.

CONCLUSION

In Fann hospital, the importance and the techniques of hand washing are not well known, that's why a training of the hospital's Personnel and an improvement of resources for handwashing are necessary for a good hospital's hygiene.

[Nosocomial Klebsiella pneumoniae infections at the Fann University Hospital Center, Dakar]

Twenty one (21) strains of Klebsiella pneumoniae are isolated from patients hospitalized since 48 hours for neurological affections, and from medical staff hands. Eighteen (18) other strains isolated from other clinics were studied for comparison. The identification used API20 E system (BioMérieux), and the susceptibility to antibiotics was tested by disc diffusion test (antibiogram). Production of extended-spectrum beta-lactamase was studied by synergy test method. Arbitrarily primed Polymerase Chain Reaction (AP-PCR) was used to compare the electrophoretic profiles of the strains. Nosocomial strains are more resistant than the other: 57.14% vs 16.67% (p = 0.02) and 28.57% among them are extended-spectrum beta-lactamase positive. Amikacin (87.5%) and Ciprofloxacin (100%) are the most efficient antibiotics, when Cotrimoxazole inhibits 31.25% of the strains. The electrophoretic profiles show an important diversity of strains and suggest an external contamination.
