The new European guidelines on the management of non-ST segment elevation acute coronary syndromes （NSTE-ACS） were published in June 2007, two months before the American College of Cardiology-American Heart Association （ACC-AHA） guideline update on the same topic.^1.2 The European Society of Cardiology （ESC） guidelines differ from the American guidelines on a certain number of points： the ESC document is much shorter,

Purpose: The aim is to show epidemiological, clinical and etiological characteristics of palpebral wounds. Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .

Flexible portable electronic devices have attracted increasing attention during the last decade. Energy consumption of such devices is ever increasing and performing power sources, that are moreover flexible, need to be developed to seamlessly integrate into such architectures. While lithium-ion batteries appear to be the best solution to meet the power and energy requirements, their structural and mechanical considerations still need to be addressed. Here, we realize and study the impact on the electrochemical performances of carbon nanotubes （CNTs） based, current collector-free and binder-free, Li-ion battery electrodes. Multi-walled carbon nanotubes acting as a mechanical and electron conductive scaffold enable structural flexibility and good electrochemical performances. Flexible Li-ion cells made with such electrodes show promising performances while being realized through simple manu- facturing approaches.
