Endoscopic Treatment of Posterior Ankle Impingement Secondary to Os Trigonum in Recreational Athletes.

Background: The os trigonum (OT)-the most common accessory bone of the foot-although usually asymptomatic, may cause posterior ankle impingement syndrome (PAIS), which may be a severely debilitating problem for recreational or competitive athletes. The aim of the present study was to evaluate effectiveness of posterior ankle arthroscopy and to assess the outcome in the treatment of PAIS secondary to OT impingement or OT fractures within a group of young athletes and their return to previous sports level.

Methods: From 2011 to 2018, a retrospective review of 81 recreational athletes of mean age 27.

Large Osteochondral Lesions of the Talus Treated With Autologous Bone Graft and Periosteum Transfer.

Background: The treatment of large osteochondral lesions of the talus (OLTs) is challenging due to the poor intrinsic reparative capability of the damaged articular cartilage. Autologous transfer of bone and periosteum has been used successfully in the treatment of large defects in animals, and therefore it was believed that this technique might show similar results in humans. The purpose of this study was to assess the outcome of an innovative technique for autologous transplantation of cancellous tibial graft with periosteal transfer in large OLTs.

The role of serum total ghrelin level elevation in colon cancer patients.

Purpose: Many studies have pointed out a possible role of ghrelin, in the pathogenesis and natural history of gastrointestinal tract malignancies. The objective of this study was to estimate serum total ghrelin levels (STGL) in patients with colon cancer (CC) and to evaluate the value of this assay in research and clinical practice.

Methods: STGL were measured pre-operatively in 95 CC patients and in 39 healthy controls, and were correlated with patients' age, gender, body mass index (BMI), tumor location, Dukes stage, grade of differentiation and patients' survival.
