The diagnosis of ankle osteoarthritis (OA) is increasing as a result of advancements in non-invasive imaging modalities such as magnetic resonance imaging, improved arthroscopic surgical technology and heightened awareness among clinicians. Unlike OA of the knee, primary or age-related ankle OA is rare, with the majority of ankle OA classified as post-traumatic (PTOA). Ankle trauma, more specifically ankle sprain, is the single most common athletic injury, and no effective therapies are available to prevent or slow progression of PTOA...

Transcatheter valve interventions have emerged as one of the most important developments in structural heart disease over the past 20 years. Initially, these interventions were directed at patients with severe aortic stenosis and high surgical risk; however, their applications have extended to involve other native valves' pathologies, degenerated prosthetic valves, as well as patients of lower surgical risk. In this article, we discuss the importance of cardiac imaging in transcatheter aortic valve replacement (TAVR) by exploring the current practices, guidelines, and recommendations with the supporting data...

This document presents a non-rigid registration algorithm for the use of brain magnetic resonance (MR) images comparison. More precisely, we want to compare pre-operative and post-operative MR images in order to assess the deformation due to a surgical removal. The proposed algorithm has been studied in Chesseboeuf et al. ((Non-rigid registration of magnetic resonance imaging of brain. IEEE, 385-390. doi: 10.1109/IPTA.2015.7367172 , 2015), following ideas of Trouvé (An infinite dimensional group approach for physics based models in patterns recognition...

Hyperglycaemia following surgical and anaesthetic stress is a well-established entity which might have undesirable clinical consequences in known diabetics. We encountered a rare event where an undiagnosed diabetic patient developed ketoacidosis in the immediate post-operative period which was her initial presenting symptom of deranged glucoregulation. Presumably, the stress induced by surgery and anaesthesia lead to the genesis of this event. We discuss the management of this case. In addition, we highlight the importance of glycosylated haemoglobin as a subject of future research in identifying such "at risk" patients and for stratifying the risk of hyperglycaemic complications in perioperative settings...

BACKGROUND AND AIMS: Laryngoscopy and endotracheal intubation are considered as potent stimuli which lead to an increase in heart rate and blood pressure. Melatonin (N-acetyl-5-methoxytryptamine) has been studied for pre-operative anxiolysis and sedation in Intensive Care Unit. We made a hypothesis that melatonin can provide haemodynamic stability during laryngoscopy and intubation when given 120 min before the procedure. METHODS: Sixty American Society of Anesthesiologists physical status Grade I and II patients of either gender, 20-45 years old, 40-65 kg body weight, scheduled to undergo elective surgical procedures under general anaesthesia were assigned into two equal groups - Group C (control) and Group M (melatonin)...

Holmium laser enucleation of the prostate (HoLEP) is a standard surgical procedure for treatment of benign prostatic hyperplasia (BPH). A low incidence of postoperative urinary incontinence in association with anteroposterior dissection HoLEP was recently reported. We evaluated 66 patients with BPH who underwent anteroposterior dissection HoLEP from March 2013 to November 2014. The International Prostate Symptom Score (IPSS), quality of life (QOL) index, maximum flow rate (Qmax), and post-void residual urine volume (PVR) were assessed preoperatively and at 1 and 3 months after treatment...

To determine the role of immunosuppressive acidic protein(IAP)in the host defense of surgical patients, we investigated the kinetics of the post-operative elevation of IAP, as well as factors influencing the increase in serum IAP concentration, in 17 patients who underwent breast surgery. IAP was not increased in the pre-operation phase, post-operation phase, or 2 weeks after surgery, byvarious breast surgerymethods. In contrast, IL-6 was increased in the post-operation phase byall breast surgerymethods. IL-6 correlated with anesthesia time...

Postoperative chemotherapy was initially conducted with surgical treatment as part of a multimodal treatment strategy for esophageal squamous cell carcinoma. Subsequently, a randomized trial comparing post- versus pre-operative chemotherapy with cisplatin and 5-fluorouracil demonstrated the superior efficacy of neoadjuvant treatment with FP(CF). However, the results of subgroup analysis based on T factor revealed no efficacy for cT3 tumors. To improve the survival rate in patients with cT3 tumors, treatments with neoadjuvant chemotherapy using FP(CF)plus docetaxel and concurrent FP(CF)plus radiation were conducted to assess the feasibility of preoperative adjuvant treatment and surgery after neoadjuvant treatment...

BACKGROUND: In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures. METHODS: Data from patients with pre-operative LVEF ≤40 % undergoing cardiac surgery at a university hospital were reviewed and analyzed...

Achieving negative surgical margins can be challenging for skull base and spinal/paraspinal sarcomas. Data shows that pre- or post-operative radiation therapy improves local control. Delivery of sufficient dose of radiation can be difficult because of the proximity to normal organs/tissues that are sensitive to radiation therapy and therefore dose-limiting. A comprehensive literature search was conducted using PubMed search engine. The scarcity of prospective, randomized data limits the ability to generate definitive treatment recommendations...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

We used resting-state fMRI to investigate regional homogeneity (ReHo) changes in patients with TN before and after PRT procedure, and to speculate about its possible mechanisms.Thirty-one TN patients underwent the PRT procedure had MRI scans just before and 6 months after surgery. The anatomical and resting-state functional images were all acquired. Patients' visual analog scales (VAS) scores, facial numbness, and disease duration were also recorded. Voxel-wise ReHo analysis was performed to detect the altered regional clusters after surgery...

OBJECTIVE: To develop a large animal model of spinal cord injury (SCI), for use in translational studies of spinal cord stimulation (SCS) in the treatment of spasticity. We seek to establish thresholds for the SCS parameters associated with reduction of post-SCI spasticity in the pelvic limbs, with implications for patients. STUDY DESIGN: The weight-drop method was used to create a moderate SCI in adult sheep, leading to mild spasticity in the pelvic limbs. Electrodes for electromyography (EMG) and an epidural spinal cord stimulator were then implanted...
