The neuromodulatory peptide somatostatin(somatotropin release inhibiting factor,SRIF)-14 acts at multiple levels through five SRIF receptor subtypes(sst1 to sst5).SRIF-28 is also derived from a common propeptide translated from a single SRIF gene,although SRIF-14 is the predominant form in the mammalian nervous *** to its short half-life,synthetic SRIF analogs have been developed over the years and are available for therapeutic approaches.

Traumatic peroneal split lesion with retinaculum avulsion:Diagnosis and post-operative multymodality imaging

World Journal of Radiology 2018年第5期10卷 46-51页

作者： Aldo Fischetti Jeries P Zawaideh davide orlandi Stefano Belfiore Enzo SIlvestri Department of Health Sciences (DISSAL) Radiology SectionUniversity of Genoa Radiology Department Ospedale Evangelico Internazionale Orthopedic and Trauma Department Ospedale Evangelico Internazionale

Tears of peroneus brevis tendon represent a cause of underdiagnosed lateral ankle pain and instability. The typical clinical presentation is retro-malleolar pain, in some cases associated with palpable swelling around the fibular malleolus, pain during activities and difficulty in walking. We present a case of peroneus brevis split lesion with superior peroneal retinaculum avulsion in a young athlete who referred to the emergency ward of our hospital for left ankle pain after an inversion injury. An early diagnosis allowed treating the injury and promptly resuming sport activity, after rehabilitation training. Surgical reconstruction key-points and postsurgical follow-up were also discussed. A late diagnosis would have caused a symptomatology worsening and an increased recovery time.
