BACKGROUND: In patients with locally advanced or low rectal cancers, long-course chemoradiotherapy (LCCRT) is recommended prior to surgical management.(1) The need for restaging afterwards has been questioned as it may be difficult to interpret imaging due to local tissue effects of chemoradiotherapy. The purpose of this study was to determine if restaging affected the management of patients receiving long-course chemoradiotherapy for rectal cancer. METHODS: A retrospective review of patients with rectal cancer discussed at the South Eastern Health and Social Care Trust Lower Gastrointestinal Multi-Disciplinary Team Meeting (LGIMDT) in 2013 who had received long-course chemoradiotherapy was performed...

BACKGROUND: The role of BRAF mutations in cancerogenesis has been demonstrated in several solid tumor types. However, in salivary gland tumors, this genetic alteration is very uncommon, and its role still remains unclear. Thus, the aim of this study was to analyze BRAF V600E (VE1) protein expression with BRAF mutation status in codon 600, in malignant and benign salivary gland tumors. METHODS: Studies were performed on archived formalin-fixed paraffin-embedded tissue sections derived from 95 patients who underwent surgery for tumors of the salivary gland...

BACKGROUND: Preoperative embolization is based on the preoperative digital subtraction angiography (DSA) tumor blush, and as such is considered the "gold standard" for determining tumor vascularity. However, to our knowledge reliability studies evaluating vascularity ratings of DSA tumor blush in spinal metastases have not been published previously. PURPOSE: To evaluate inter- and intra-rater agreement in the assessment of the vascularity of spinal metastases using DSA tumor blush...

OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning. Augmented reality based on an Android smartphone app, Sina neurosurgical assist, allowed a projection of the hematoma to be seen on the patient's scalp to facilitate selection of the best trajectory to the center of the hematoma...

OBJECTIVE: During total hip arthroplasty (THA), the location of the acetabular prosthesis is very important for guaranteeing successful surgery. However, this remains a challenge for many surgeons. This study aimed to investigate the feasibility of using the intraoperative fluoroscopic iliopubic tangential angle (IPTA) to determine the valgus angles of acetabular prostheses. METHODS: In the first stage, the IPTA and valgus angles of native acetabula were defined and measured in 102 THAs obtained from the picture archiving and communication systems of our hospital...

BACKGROUND: Idiopathic purulent mesenteric lymphadenitis or lymph node abscessation, even though rare in dogs, are important diseases in which rapid diagnosis and treatment is critical. This study aimed to characterise the typical features of these conditions in dogs. MATERIAL AND METHODS: Archived records from 2005 to 2015 were retrospectively evaluated for the occurrence of idiopathic purulent mesenteric lymphadenitis or lymph node abscesses in dogs. History, physical and clinicopathological abnormalities, diagnostic tests performed, treatment and outcome were reviewed...

PURPOSE: The purpose of the study was to compare the rate of secondary resurfacing in a consecutive series of five different total knee arthroplasty (TKA) systems. It was our hypothesis that different TKA design features such as sulcus angle or trochlear height influence the rate of secondary resurfacing. METHODS: A retrospective study was performed on data from patients who underwent TKA without primary patellar resurfacing from 2004 to 2012 in an university-affiliated hospital...

BACKGROUND: Increasing experience with minimally invasive surgery and the development of new instruments has resulted in a tendency toward reducing the number of abdominal skin incisions. Retrospective and randomized prospective studies could show the feasibility of single-incision surgery without any increased risk to the patient. However, large prospective multicenter observational datasets do not currently exist. OBJECTIVE: This prospective multicenter observational quality study will provide a relevant dataset reflecting the feasibility and safety of single-incision surgery...

AIM: Meningioma literature has many large surgical case series which have been references of text books and neurosurgical practice. Many of those series were investigated before stereotactic radiosurgery (SRS) practice were not so often or were in terms of WHO 2000 classification. In this study we aimed an update to the current literature by using WHO 2007 classification. MATERIAL AND METHODS: 488 intracranial meningioma patients underwent open surgery. All pathological specimens re-evaluated in terms of WHO 2007 classification...

INTRODUCTION: Treatment-limiting decisions (TLDs) are employed to actively withhold treatment from patients whom clinicians feel would derive no benefit or suffer detrimental effects from further intervention. The use of such decisions has been heavily discussed in the media and clinicians in the past have been reluctant to institute them, even though it is in the best interests of the patients. Their use is influenced by several ethical, religious and social factors all of which have changed significantly over time...

OBJECTIVE: Adrenal hemorrhages arise as a result of a number of conditions and may exhibit a variety of appearances on computed tomography (CT). On occasion, patients will undergo adrenalectomy for treatment of a presumptive adrenal neoplasm that on surgical pathology is identified as an adrenal hemorrhage. We evaluated the CT appearance of surgically resected adrenal masses from our institution over a period of 15 years that ultimately proved to be adrenal hematomas. METHODS: A surgical pathology archive was queried for all cases of adrenal hemorrhage...

BACKGROUND CONTEXT: Timely interpretation of computed tomography (CT) scans is of paramount importance in diagnosing and managing spinal column fractures, which can be devastating. Out-of-hospital, on-call spine surgeons are often asked to evaluate CT scans of patients who have sustained trauma to the thoracolumbar spine to make diagnosis and to determine the appropriate course of urgent treatment. Capturing radiographic scans and video clips from computer screens and sending them as instant messages have become common means of communication between physicians, aiding in triaging and transfer decision-making in orthopedic and neurosurgical emergencies...

BACKGROUND: Periprothetic infection after primary or revision arthroplasty is of increasing importance. The incidence of infection in primary arthroplasty is approximately 1 %. Revision arthroplasty has higher infection rates, which increase with the number of revision surgeries. Aim of this Paper: An overview of the current diagnosis of periprosthetic infection. METHODS: This selective analysis is based on a lecture by the author at the DKOU 2015. RESULTS: Periprosthetic infection is taken as having been demonstrated when either two periprosthetic cultures contain the same microorganism, or if there is a fistula communicating with a joint...

OBJECTIVE: Endolymphatic hydrops has been well described in patients with Ménière's syndrome; however, causation has not been established. Decompression of the endolymphatic sac has been proposed as a means to relieve hydrops and improve vertigo symptoms, but the efficacy of the surgery is debated. Until recently, there have been few objective measures of efficacy other than patients' subjective symptoms. Recent archival human temporal bone studies have shown that patients continue to have hydrops after shunt surgery...
