AIMS: Cell communication between mesenchymal stem cells and blood vessel cells are crucial for bone repair. We have previously shown that the phyto-molecule icariin significantly promoted osteogenic differentiation of rat adipose-derived stem cells (ASCs). In the present study, we aimed to investigate the relationship between icariin induced osteogenic differentiation of ASCs and angiogenesis of rat endothelial progenitor cells (EPCs). Besides, we used icariin doped 45S5 Bioglass seeded with ASCs to promote bone healing in rat calvarial bone defect models...

BACKGROUND: Established practice for the management of soft tissue sarcoma (STS) of the extremity and trunk wall combines perioperative radiotherapy (RT) with limb-preserving surgery. OBJECTIVE: The aim of this study was to explore whether high-quality surgery at high-volume centers may offer equivalent local control in selected cases, when RT needs to be avoided. METHODS: All consecutive adult cases of primary, high-risk STSs treated in a high-volume reference center over a 12-year timeframe were included, and, on retrospective analysis, were divided into two groups...

Traumatic knee dislocation is a rare but potentially limb-threatening injury. Thus proper initial diagnosis and treatment up to final ligament reconstruction are extremely important and a precondition to successful outcomes. Reports suggest that evidence-based systematic approaches lead to better results. Because of the complexity of this injury and the inhomogeneity of related literature, there are still various controversies and knowledge gaps regarding decision-making and step-sequencing in the treatment of acute multi-ligament knee injuries and knee dislocations...

Patients with complex regional pain syndrome (CRPS) exhibit diverse symptoms, such as neuropathic pain, allodynia, local edema and skin color changes in the affected lesion. Although nerve injury may cause CRPS, pathophysiological mechanisms underlying the syndrome are unclear, and local edema, a characteristic of CRPS, has not been evaluated quantitatively for technical reasons. Here, using a rat spinal nerve ligation-induced CRPS model, we show that edematous changes in gastrocnemius muscle can be detected quantitatively by diffusion magnetic resonance imaging (MRI)...

Background: After almost two decades, transabdominal robotic radical prostatectomy techniques have been fully developed and are widely practiced by many robotic urologists. Recently, a transperineal robotic radical prostatectomy, a technique not yet popular to many, was introduced as an alternative approach in patients with previous abdominal surgery. Here, we present our unique experience with robotic perineal radical prostatectomy (r-PRP) on a kidney transplant recipient. Case Presentation: A 71-year-old man who had a kidney transplant 4 months previously was diagnosed with prostate cancer (PCa) and underwent r-PRP using the da Vinci Xi robotic system...

The aim of the present study was to examine the utility of convex endoscopic ultrasonography (EUS) for the preoperative vascular evaluation of malignant biliary tract neoplasm, by comparing EUS findings with histological findings from resected specimens. Between January 2008 and January 2016, the present study retrospectively retrieved 82 cases diagnosed with malignant biliary tract neoplasm to compare findings from convex EUS with histological findings from resected specimens. A total of four groups were defined according to the results of EUS of the hepatic artery (HA) and portal vein (PV): Group 1, hyperechoic tissue between tumor and vessel; group 2, close proximity between tumor and vessel without loss of hyperechoic tissue; group 3, tumor and vessel contiguity, with loss of hyperechoic tissue; and group 4, encasement >180°...

Pneumatosis intestinalis (PI) and portomesenteric venous gas (PVG) refers to the presence of air within the intestinal wall and portomesenteric vessels. Most of the time, it is associated with mesenteric ischemia that requires immediate surgical intervention as it has high mortality rate. It may also be seen secondary to various conditions, including infections, surgeries, and some chemotherapeutic drugs. A 61-year old-male was admitted to our emergency department complaining of abdominal pain after chemotherapy...

Background: Vascularized composite tissue allotransplantation (VCA) from a cadaveric donor has now become a clinical reality and the treatment modality of choice for patients with devastating injuries, deformities, and complex tissue defects. However, many VCA patients experience severe toxicities due to the strong immunosuppression required secondary to high antigenicity of the grafts. To improve immunosuppressive protocols for VCA, feasible and reliable preclinical models are necessary...

Replantation is the reattachment of a severed body part, with attempts to restore neurovascular and musculoskeletal integrity, function, and aesthetics. On September 7, 1964, the first extremity replantation-a completely amputated hand-by vascular anastomosis technique was successfully performed.1 Soon after, the first replantation of a complete thumb amputation using microvascular anastomosis in a human was successfully conducted by Komatsu et al.2 in 1968. The overall success rate of limb replantation surgery is around 83...

Objective: Over the past few years, virtual surgical planning (VSP) has evolved into a useful tool for the craniofacial surgeon. Virtual planning and computer-aided design and manufacturing (CAD/CAM) may assist in orthognathic, cranio-orbital, traumatic, and microsurgery of the craniofacial skeleton. Despite its increasing popularity, little emphasis has been placed on the learning curve. Methods: A retrospective analysis of consecutive virtual surgeries was done from July 2012 to October 2016 at the University of Montreal Teaching Hospitals...

BACKGROUND: In patients with critical leg ischemia (CLI), the standard operative choice is an in situ bypass to the lower extremity to improve the patients´ prognosis and quality of life. Postoperative complications after surgery occur in 18 % of the patients, prolonging hospitalization and convalescence. The main operative complication is edema. This can be prevented by early mobilization or stimulation of the natural venous pump in the leg. OBJECTIVE: To investigate whether compression therapy with foot pump reduces postoperative edema, facilitates wound healing of the operation wounds, promotes healing of ischemic ulcers, and shortens hospitalization, increasing and improving the patient's subjective quality of life faster...

BACKGROUND: Postpartum haemorrhage (PPH) - heaving bleeding within the first 24 hours after giving birth - is one of the main causes of death of women after childbirth. Antifibrinolytics, primarily tranexamic acid (TXA), have been shown to reduce bleeding in surgery and safely reduces mortality in trauma patients with bleeding without increasing the risk of adverse events.An earlier Cochrane review on treatments for primary PPH covered all the various available treatments - that review has now been split by types of treatment...

The surgical connection of blood vessels, anastomosis, is a critical procedure in many reparative, transplantation, and reconstructive surgical procedures. However, effective restoration of circulation is complicated by pathological clotting (thrombosis) or progressive occlusion due to excess cell proliferation that often leads to additional surgeries and increases morbidity and mortality risk for patients. Pharmaceutical agents have been tested to prevent these complications, but many have unacceptable systemic side effects...
