background: because nerve stimulators are not always available for brachial plexus block, fmding the right injection spot for nerve blocks is important. in this study we used physical examination to determine the appropriate spot for injection. methods: all patients who were candidates for upper extremity surgery and were either in class asa i or asa ii, were selected. paresthesia was elicited ...

objectives thereby the prevalence, distribution characteristics and correlative factors of oa in mongolian middle-aged and senior residents in the inner mongolia autonomous region were investigated in this study. materials and methods rural and urban residents in hohhot, baotou and erdos were selected using stratified, multi-stage and cluster random sampling. 2000 residents aging over 45 filled...

BACKGROUND Advances in technology have pushed the boundaries of neurosurgery. Surgeons play a major role in the neurosurgical field, but robotic systems challenge the current status quo. Robotic-assisted surgery has revolutionized several surgical fields, yet robotic-assisted neurosurgery is limited by available technology. METHODS The literature on the current robotic systems in neurosurgery...

Tele-examination based on robotic technologies is a promising solution to solve the current worsening shortage of physicians. Echocardiography among examinations that would benefit more from solutions. However, most state-of-the-art solutions are development specific arms, instead exploiting COTS (commercial-off-the-shelf) arms reduce costs and make such systems affordable. In this paper, we ad...

We introduce a robotic wheelchair that can move with a companion collaboratively to facilitate easy communication between them. The system uses the Laser Range Sensor attached horizontally on the companion’s shoulder level for observing the companion’s position to follow him/her. The system tracks the companion’s position and orientation to move with the companion and to avoid collision with hi...

Abstract Background Gastrointestinal vascular malformations are rare benign neoplasms of the gastrointestinal tract, with rectosigmoid region being most frequently involved site. Patients often manifest recurrent, intermittent rectal bleeding, which might occasionally be life-threatening. Case presentation A 39-year-old man a history hemorrhoid operations twice was presented to our gastroentero...

Robotic surgery, used generally for colorectal cancer, has the advantages of a three-dimensional surgical view, steadiness, and seven degrees of robotic arms. However, there are disadvantages, such as a decreased sense of touch, extra time needed to dock the robotic cart, and high cost. Robotic surgery is performed using various techniques, with or without laparoscopic surgery. Because the resu...

BACKGROUND Robotic thyroidectomy and conventional endoscopic thyroidectomy have not been thoroughly compared. In this study, we compared the potential advantages of robotic versus endoscopic thyroidectomy. METHODS We analyzed 218 consecutive patients who underwent endoscopic (105 cases) or robotic (113 cases) thyroidectomy using a gasless unilateral axillo-breast or gasless unilateral axillar...
