African coastal camera network efforts at monitoring ocean, climate, and human impacts.

Regular and long-term monitoring of coastal areas is a prerequisite to avoiding or mitigating the impacts of climate and human-driven hazards. In Africa, where populations and infrastructures are particularly exposed to risk, there is an urgent need to establish coastal monitoring, as observations are generally scarce. Measurement campaigns and very high-resolution satellite imagery are costly, while freely available satellite observations have temporal and spatial resolutions that are not suited to capture the event scale. To address the gap, a network of low-cost, multi-variable, shore-based video camera systems has been installed along the African coasts. Here, we present this network and its principle of sharing data, methods, and results obtained, building toward the implementation of a common integrated coastal management policy between countries. Further, we list new contributions to the understanding of still poorly documented African beaches' evolution, waves, and sea level impacts. This network is a solid platform for the development of inter-disciplinary observations for resources and ecology (such as fisheries, and sargassum landing), erosion and flooding, early warning systems during extreme events, and science-based coastal infrastructure management for sustainable future coasts.

[Pain during peritoneum pinching, a pathognomonic sign of peritoneal disease. Clinical research. Semiological value]. / La douleur au pincement du péritoine, signe pathognomonique d'affection péritonéale. Recherche clinique. Valeur séméiologique.

Pain induced by pinching the peritoneum betrays a pathology of that membrane. It is absent when the peritoneum is perfectly healthy. Pain is elicited by a special palpation technique. Clinically and statistically, the presence of this pain is pathognomonic, but it does not inform on the aetiology. In the present study the most frequent causes of positive abdominal peritoneal pinching test were peritoneal tuberculosis, followed by portal hypertension with or without liver cirrhosis.

[Stopping persistent hiccups in the adult by endoscopic maneuver]. / Arrêt du hoquet persistant de l'adulte par manoeuvres endoscopiques.

Thirty-four patients with persistent hiccups (median duration 10 days) were treated by gentle endoscopic massage of the region of the cardia. Hiccups stopped in all cases. Its early recurrence in one patient only required a second massage, which was also effective. This simple technique is recommended for the treatment of persistent hiccups.
