PURPOSE: The clinical and radiographic outcomes after revision total knee arthroplasty (TKA) for instability with two rotating hinge knee prostheses were compared. METHODS: Fifty-one patients revised for TKA instability were prospectively randomized to either the Link Endo-Model (N = 26) or the EnduRo (N = 25). Clinical and radiographic outcome scores were compared pre-operatively and at 12 months' follow-up. Failure mechanisms were recorded. RESULTS: Age, BMI, operation, and tourniquet-time did not differ significantly between groups...

Julia Booth, Tim Morse
Digit hair tourniquets are relatively uncommon. There are reports in the literature of hair tourniquets involving other appendages, such as the penis and uvula, however the phenomenon is not widely recognised and is often overlooked by healthcare professionals. This article discusses two case studies in which hair was responsible for creating a tourniquet around a digit. The article explores possible causes and management options for patients, with reference to the case studies. Midwives and health visitors are central to minimising the risk of injury to children as they can educate expectant mothers about this potential problem...

The aim of the study was to find out what perioperative risk factors predicted complications in patients having reconstructions with radial forearm free flaps (RFFF). We organised a retrospective study of 169 patients (mean (range) age 54 (22-86) years, 100 of whom were female) who had oral and maxillofacial tumours resected, and reconstructed with RFFF, from January 2011-December 2016. We recorded predictive variables, subdivided into: personal and clinical (sex, age, weight, coexisting conditions, history of smoking, radiotherapy, and primary lesions); haemodynamic (perioperative concentrations of haemoglobin and albumin, blood loss, blood transfusion, urinary output (ml), and rate (ml/kg/hour), and infusion rates for crystalloids and colloids (ml/kg/hour, and volumes given intraoperatively and postoperatively for 24hours); and anaesthetic and surgical (American Society of Anesthesiologists(ASA) grade, visual analogue pain score (VAS), and duration of tourniquet and operation)...

Electrical burns are responsible for arterial and venous thrombosis, as well as weakening of the arteries. Immediate or delayed arterial occlusions, secondary to the aggression of the intima, or aneurysms, secondary to the aggression of the media, sometimes lead to artery ruptures without any warning signs. Such ruptures may trigger a hemorrhagic shock whose period of onset is variable and unpredictable. We are presenting here three cases treated in our department for electrical burns, whose complications were marked by hemorrhagic shock, secondary to late artery ruptures, sometimes occurring several months following the event...

Introduction: Methicillin resistant Staphylococcus aureus (MRSA) is transmitted through direct contact or fomites. The most important means of nosocomial spread is by hospital personnel. However, fomites are being increasingly recognized as sources of nosocomial infection. Objectives: Our aim was to describe the MRSA contamination rate of phlebotomy tourniquets and faucets in a tertiary care hospital and to compare the contamination of plastic tourniquets with that of fabric tourniquets...

The risk of hemorrhage always exists in anticoagulated patients with an elevated international normalized ratio (INR), a risk that must be measured against the necessity for surgical procedures. The objective of the present retrospective medical record study was to assess the safety with which limb salvage procedures can be conducted in patients with an INR >1.4. The medical records of 231 patients who had undergone limb salvage procedures by 1 surgeon at the Yale New Haven Health System from November 2008 through July 2014 were reviewed...

Background: Total arterial occlusive pressure (AOP) is used to prescribe pressures for surgery, blood flow restriction exercise (BFRE) and ischemic preconditioning (IPC). AOP is often measured in a supine position; however, the influence of body position on AOP measurement is unknown and may influence level of occlusion in different positions during BFR and IPC. The aim of this study was therefore to investigate the influence of body position on AOP. Methods: Fifty healthy individuals (age = 29 ± 6 y) underwent AOP measurements on the dominant lower-limb in supine, seated and standing positions in a randomised order...

BACKGROUND: Remote ischemic preconditioning (RIPC) can be protective against the damage. However, there is no consensus on the optimal amount of tissue, the number and duration of the ischemic cycles, and the timing of the preconditioning. The hemorheological background of the process is also unknown. OBJECTIVE: To investigate the effects of remote organ ischemic preconditioning on micro-rheological parameters during liver ischemia-reperfusion in rats. METHODS: In anesthetized rats 60-minute partial liver ischemia was induced with 120-minute reperfusion (Control, n = 7)...

BACKGROUND: Renal cell carcinoma has a natural tendency to extend through the renal vein. When the thrombus reaches the vena cava, thrombectomy and the necessary reconstruction of the vena cava are typically performed by open pathway. Robot-assisted technology provides advantages for performing this complex technique, using a minimally invasive access. MATERIAL AND METHODS: We present the technique we employed in the first case performed in our department. After performing renal artery embolisation, we conducted the surgery with the Vinci S robotic system...

Purpose: Obesity can result in increased blood loss, which is correlated with poor prognosis in total knee arthroplasty (TKA). Clinical application of tranexamic acid is effective in reducing blood loss in TKA. However, most previous studies focused on the effect of tranexamic acid in the whole population, neglecting patients with specific health conditions, such as obesity. We hypothesized that tranexamic acid would reduce blood loss to a greater extent in obese patients than in those of normal weight...

BACKGROUND: Mortality following shooting is related to time to provision of initial and definitive care. An understanding of the wounding pattern, opportunities for rescue, and incidence of possibly preventable death is needed to achieve the goal of zero preventable deaths following trauma. METHODS: A retrospective study of autopsy reports for all victims involved in the Pulse Nightclub Shooting was performed. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author...

REVIEW
Bryan G Fry
Many issues and complications in treating snakebite are a result of poor human social, economic and clinical intervention and management. As such, there is scope for significant improvements for reducing incidence and increasing patient outcomes. Snakes do not target humans as prey, but as our dwellings and farms expand ever farther and climate change increases snake activity periods, accidental encounters with snakes seeking water and prey increase drastically. Despite its long history, the snakebite crisis is neglected, ignored, underestimated and fundamentally misunderstood...
