[Focus on high speed rotational atherectomy by Rotablator in 2021 and datas from France PCI registry].

Developed in the late 1980s, rotational atherectomy has raised a lot of hope for its innovative principle of selective ablation, allowing volume reduction (instead of redistribution) of atherosclerotic plaque, while sparing healthy tissue. Long shunned for its disappointing results on restenosis, the Rotablator finally reasserted itself in the 2000s; era of drug eluting stents and coronary angioplasty boom, thus generating emergence of complex lesions. Indeed, the Rotablator has demonstrated an undeniable benefit in complex (type C) and calcified lesions preparation (before stenting), with a procedural success rate of 95%.

A new Tier 3 method to calculate methane emission inventory for ruminants.

Livestock is the main source of methane (CH) emissions. It is important to accurately determine emissions from ruminants that meet standardized international guidelines for national greenhouse gas inventories. A new method to improve the accuracy of CH emissions that complies with IPCC rules for a Tier 3 method is described and evaluated.

[Conservative transmandibular lateral pharyngectomy in cancer of the lateral oropharyngeal wall].

The authors present conservative transmandibular lateral pharyngectomy (CTLP) as a substitute for BPTM operations in cancers of the tonsillar region. The mandible is sectioned along the symphyses and the oropharynx is widely exposed through an incision of the pelvilingual sulcus. The authors propose a primary operability criterion that allows to salvage the mandibular angle, which is usually sacrificed.
