Polyradiculoneuropathies (PRNs) are inflammatory disorders of the peripheral nervous system. They are diffuse in general, sparing neither the proximal portions of the elements of this system, where they predominate, nor the cranial nerves. To describe the epidemiological and diagnostic profiles, as well as the course, of patients with PRN in the Cocody university hospital center (Abidjan) neurology department over the past six years. This retrospective single-center study describes PRN cases and their course during the 6-year period of 2009-2014 in this neurology department. Among 5319 cases seen in the neurology department over the study period, 58 patients met our criteria, i.e., 1.1%. More patients were men: 55.2% for a sex ratio of 1.23. They included 4 cases of ethanol poisoning, 2 cases of undecompensated diabetes, and one reaction to vaccination for yellow fever (AAV). The electroneuromyographic tracing supported a finding of demyelination in 55.1%, axonal loss in 25.9% and both in 19%. PRN is a relatively common pathology that is often overlooked. Etiological investigation was difficult in our setting. Early management can improve the prognosis of this disorder.

We report the case of a French soldier deployed in Chad, who developed disabling pollakiuria after starting antimalarial prophylaxis by doxycycline. This rare secondary effect is not mentioned in reference books.

Cervicothoracic cellulitis is a very serious, potentially life-threatening infection of the cervical and thoracic soft tissue. It is a genuine medical and surgical emergency with substantial mortality, and its surgical therapy has not yet been standardized. It spreads through the layers of the cervical fascia and can then disseminate to the mediastinum and the pleural cavities, requiring specific management that includes the thoracic surgeon. We present reports of 3 patients with cervicothoracic cellulitis, all complicated by mediastinitis, with pericardial effusion in 1 case and unilateral or bilateral pyothorax in 2 cases. Combining these cases with a review of the literature enables us to describe the management of these complicated cases as seen by a thoracic surgeon.

After presentations of the principles of limb salvage and soft-tissue coverage for Gustilo III open tibia fractures, this third part is dedicated to management of tibial non-unions in low-resource settings. Inter-tibiofibular grafting and the induced membrane technique are preferred because they make it possible to deal with almost all situations. Key technical points of these methods are presented, followed by treatment guidelines based on Catagni's classification and bone defect size.

The objective of this work was to identify possible correlations between physicochemical parameters (water temperature, water flow velocity, electrical conductivity, dissolved oxygen, salinity, pH, nitrates, and phosphates) and the spatial distribution in the Senegal River delta of snail species that are intermediate hosts of human schistosomes. Eight water points (ME1 to ME4, NE1 and NE2, TA1 and TA2) were selected in the villages of Menguègne Boye, Ndellé Boye, and Thilla for biweekly monitoring of these snails and the physicochemical parameters of the water. The results show that the spatial distribution of the snail populations is related to pH, dissolved oxygen (mg/l), conductivity, temperature (̊C), and water flow velocity (m/s).

The most recent international symposium on research on healthcare systems took place in Liverpool in October, 2018. Its theme was the promotion of healthcare systems for all in the era of the Sustainable Development Goals. This biennial event is the occasion to bring together all the players in this domain- researchers, policy-makers, and field workers - to share the newest work. Numerous subjects were raised, some of them mentioned in the article: quality of care in healthcare systems through the necessary improvement in the practices of professionals, the issues of scaling up health interventions, mobilization of knowledge for the development of public policy, and the role of the private sector. Although this field has developed greatly over the past 20 years and has become central in both development aide and international health, it remains relatively little known in the French-speaking world and France is largely absent from it.

Its climate and environmental conditions put Niger at particularly high risk of the spread of Aedes mosquitoes, which can transmit arboviruses. In September 2016, the Republic of Niger reported its first outbreak of Rift Valley Fever (RVF) in the northern region of Tahoua, near the Mali border, particularly in the departments of Tchintabaraden, Tassara, and Abalak. The history of RVF has showed that epidemics and epizootics have a considerable socioeconomic impact in affected countries, such as Niger, whose populations are particularly concerned by livestock farming. Cross-sectional studies were conducted to investigate the abundance of Aedes aegypti and the risk of arbovirus transmission in 54 villages between 2002 and 2017. Sampling took place in 27 villages, with three methods used in each village: (a) capture of aggressive female mosquitoes landing on human adult volunteers from three households, both indoors and outdoors, during two consecutive nights ; (b) insecticide spray collections of resting mosquitoes early in the morning in five selected dwellings, different from those chosen for landing catches, and (c) capture by four Centers for Disease Control (CDC) light traps, both indoors and outdoors, for two nights. The remaining 27 villages were sampled only by insecticide spray collection of resting mosquitoes. The inventory, distribution, and abundance of mosquito species found at the sampled localities were evaluated. The mosquitoes (Culicidae) caught belonged to four genera, namely: Anopheles spp., Aedes spp., Culex spp. and Mansonia spp. Besides these Culicidae, other biting Diptera (Phlebotomes) were found during the capture. À total of 130,424 adult mosquitoes was caught during the study, 2.6% (3,444/130,423) of them Aedes spp. Aedes aegypti accounted for 96.6% of the Aedes spp. captured. Ae. Aegypti was collected in 41.0% (22/54) of the villages and was abundant (accounting for more than 15% of all mosquitoes captured) in 5 localities. The presence, geographical distribution, and abundance of Ae. aegypti near and in human habitations suggest a high risk of arbovirus transmission in Niger. The high abundance of arbovirus vectors encountered in this study should be a source of concern. Our observations highlight the importance of quantifying and monitoring the risk of arbovirus transmission in Niger. These results are of great importance for public health.
