Visualizing one's own painful body part appears to have an effect on reported pain intensity. Furthermore, it seems that manipulating the size of the viewed image can determine the direction and extent of this phenomenon. When visual distortion has been applied to clinical populations, the analgesic effects have been in opposition to those observed in some experimental pain models. To help resolve this problem, we explored the effect of visualisation and magnification of the visual image on reported pain using a delayed onset muscle soreness (DOMS) pain model. ⋯ We present delayed onset muscle soreness as a model for exploring visually induced analgesia. Our findings suggest that this phenomenon is expressed differently in exogenous and endogenous experimental pain models. Further exploration may offer a potential pathway for the integration of visual analgesia into the management of clinical pain.

Pulmonary artery anastomosis stenosis is a rare cause of right ventricular failure after orthotopic heart transplantation. In this case report, direct ultrasound of the pulmonary artery helped diagnose stenosis at a location not visible on transesophageal echocardiography or even with standard epicardial ultrasound views. It is important to evaluate all vascular anastomoses after heart or lung transplantation because surgical revision of these lesions is facile, but if left undiagnosed, significant morbidity or mortality is likely.

Tranexamic acid (TXA), an antifibrinolytic, is routinely used to decrease transfusion rates in total joint replacement surgery. While recent publications have indicated a low risk of TXA-associated thromboembolic events in this orthopedic population, few studies specifically address the safety of TXA administration in high-risk patients. We present a case of acute coronary thrombus requiring emergent intervention in a patient with indwelling coronary stents who underwent shoulder arthroplasty with TXA administration.

Cyclosporine before Coronary Artery Bypass Grafting Does Not Prevent Postoperative Decreases in Renal Function: A Randomized Clinical Trial.
Acute kidney injury is a common complication after cardiac surgery, leading to increased morbidity and mortality. One suggested cause for acute kidney injury is extracorporeal circulation-induced ischemia-reperfusion injury. In animal studies, cyclosporine has been shown to reduce ischemia-reperfusion injury in the kidneys. We hypothesized that administering cyclosporine before extracorporeal circulation could protect the kidneys in patients undergoing cardiac surgery. ⋯ Administration of cyclosporine did not protect coronary artery bypass grafting patients from acute kidney injury. Instead, cyclosporine caused a decrease in renal function compared to placebo that resolved after 1 month.

The American Board of Anesthesiology recently introduced the BASIC Examination, a component of its new staged examinations for primary certification, typically offered to residents at the end of their first year of clinical anesthesiology training. This analysis tested the hypothesis that the introduction of the BASIC Examination was associated with an acceleration of knowledge acquisition during the residency training period, as measured by increments in annual In-Training Examination scores. ⋯ These results support the hypothesis that the introduction of the BASIC Examination is associated with accelerated knowledge acquisition in residency training and provides evidence for the value of the new staged system in promoting desired educational outcomes of anesthesiology training.
