Blood cell differential count discretisation modelling to predict survival in adults reporting to the emergency room: a retrospective cohort study.

Objectives: To assess the survival predictivity of baseline blood cell differential count (BCDC), discretised according to two different methods, in adults visiting an emergency room (ER) for illness or trauma over 1 year.

Design: Retrospective cohort study of hospital records.

Setting: Tertiary care public hospital in northern Italy.

Does preoperative stent positioning in obstructive left sided colon cancer increase the risk of perineural invasion?

Colonic stenting as a bridge to surgery has been shown to be a safe and effective treatment for left-sided malignant colonic obstruction depending on local expertise. However, concerns still exist regarding its oncological safety. In particular, several reports showed an increased prevalence of perineural tumor invasion following stent placement.

Quasi-elective left colectomy after endoscopic colon stenting for obstructive cancer yields comparable oncologic outcome to full-elective operation.

Purpose: Whether deferring surgery after endoscopic self-expandable metal stent (SEMS) placement for neoplastic stricture, and operating patients in a quasi-elective situation, may result in similar oncologic outcomes to elective operations is unclear. This study aimed to evaluate the disease-free survival (DFS) rates of patients who underwent an interval colon resection after SEMS placement or an elective operation with comparable cancer stages.

Methods: From a prospective dataset, we retrospectively selected patients with the following characteristics: (1) left-sided colon cancer and (2) cancer stage I to III.

Spontaneous patella fracture associated with anterior tibial tubercle pseudarthrosis in a revised knee replacement following knee arthrodesis.

Background: Conversion of a knee arthrodesis to a Total Knee Arthroplasty is an uncommon procedure. Revision Total Knee Arthroplasty in this setting presents the surgeon with a number of challenges including the management of the extensor mechanism and patella.

Case Presentation: We describe a unique case of a 69 years old Caucasian man who underwent a revision Total Knee Arthroplasty using a tibial tubercle osteotomy after a previous conversion of a knee arthrodesis without patella resurfacing.
