[Toxicology of synthetic cannabinoids].

Synthetic cannabinoids (CS), or synthetic endocannabinoid receptor agonists, were initially synthesized for basic research into exocannabinoid signaling pathways, as well as in clinical research for their analgesic properties. The use of CS for recreational purposes is a recent phenomenon, but one that has grown very quickly in recent years, since these molecules now represent the main category of new synthetic products (NPS). This literature review aims to bring together current data regarding the use and effects caused by CS in humans.

Computed Tomography Colonography Angiography (CTC-A) prior to colectomy for cancer: A new tool for surgeons.

The pre-operative work-up for non-metastatic colon cancer includes colonoscopy and thoraco-abdomino-pelvic computed tomography (CT) with intravenous (IV) contrast. Colonoscopic determination of the anatomical location of the tumor may be erroneous, particularly with a long redundant colon (dolichocolon), and the search for synchronous colon neoplasms is limited when the endoscope cannot traverse the tumor-bearing segment. While computed tomography colonography angiography (CTC-A) makes it possible to assess distant tumor metastasis, it remains limited for the assessment of loco-regional extension.
