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.

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).

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 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.

Posttraumatic diaphragmatic hernias have long been known, but the variety of their clinical expression can lead to diagnostic delay and difficulties in treatment. An intrathoracic hernia of hollow abdominal viscera with subsequent necrosis and perforation is an uncommon late complication with poor prognosis. Surgical treatment is mandatory. Laparotomy is an excellent approach, making it possible to achieve therapeutic objectives for the abdomen and thorax with a short operative time and minimal complications in these patients whose hemodynamic status is often precarious. We report 2 cases of posttraumatic left diaphragmatic hernias with intrathoracic necrosis of the digestive tract, treated by laparotomy.

There is currently a hazardous debate between the rational use of antimalarial drugs based on artemisinin derivatives and the antimalarial efficacy of plant extracts of Artemisia spp. This article recall some fundamental rules guiding progresses in malaria treatment and use of artemisinin, with the aim to provide discussion elements to identify the safest place responding to health situations for drugs and phytotherapy.
