Insulin-dependent diabetes mellitus is associated with shoulder stiffness and a propensity toward postoperative wound complications and infection. We compared our results of open repair of full-thickness rotator cuff tears in 30 diabetic patients with those of a matched, nondiabetic population. No differences were observed in preoperative range of motion,(More)
OBJECTIVES We aimed to examine the association between total number of resected nodes and survival in patients after esophagectomy with and without nCRT. BACKGROUND Most studies concerning the potentially positive effect of extended lymphadenectomy on survival have been performed in patients who underwent surgery alone. As nCRT is known to frequently(More)
BACKGROUND Initial results of the ChemoRadiotherapy for Oesophageal cancer followed by Surgery Study (CROSS) comparing neoadjuvant chemoradiotherapy plus surgery versus surgery alone in patients with squamous cell carcinoma and adenocarcinoma of the oesophagus or oesophagogastric junction showed a significant increase in 5-year overall survival in favour of(More)
The indications for glenohumeral arthroplasty are severe pain and restricted range of motion associated with radiographic evidence of advanced glenohumeral arthritis. Nonsurgical management consisting of rest, physical therapy, and antiinflammatory medication should be tried before considering surgical management. It is important that each patient be(More)
PURPOSE Esophageal adenocarcinoma (EAC) is a highly aggressive disease with poor long-term survival. Despite growing knowledge of its biology, no molecular biomarkers are currently used in routine clinical practice to determine prognosis or aid clinical decision making. Hence, this study set out to identify and validate a small, clinically applicable(More)
