By controlling robots comparable to the human body, people with profound motor deficits could potentially perform a variety of physical tasks for themselves, improving their quality of life. The extent to which this is achievable has been unclear due to the lack of suitable interfaces by which to control robotic body surrogates and a dearth of studies involving substantial numbers of people with profound motor deficits. We developed a novel, web-based augmented reality interface that enables people with profound motor deficits to remotely control a PR2 mobile manipulator from Willow Garage, which is a human-scale, wheeled robot with two arms...

PURPOSE: As the trend toward minimally invasive and percutaneous interventions continues, the importance of appropriate surgical data visualization becomes more evident. Ineffective interventional data display techniques that yield poor ergonomics that hinder hand-eye coordination, and therefore promote frustration which can compromise on-task performance up to adverse outcome. A very common example of ineffective visualization is monitors attached to the base of mobile C-arm X-ray systems...

OBJECTIVE: The aim of surgical stabilization of proximal humerus fractures is to restore the anatomical relations between the greater and lesser tubercle, to reconstruct the joint and preserve the vascular supply of the fragments. INDICATIONS: Approximately 80% of proximal humeral fractures can be treated conservatively. Surgical treatment is indicated based on the fracture pattern, patient-related factors and the risk of avascular head necrosis. Two-part fractures with a metaphyseal comminution zone and 3/4-part fractures can benefit from near to anatomic reconstruction depending on the patient's demands and bone quality...

The reconstruction of anatomical joint surfaces, limb alignment and rotational orientation are crucial in the treatment of fractures in terms of preservation of function and range of motion. To assess reduction and implant position intra-operatively, mobile C-arms are mandatory to immediately and continuously control these parameters.Usually, these devices are operated by OR staff or radiology technicians and assessed by the surgeon who is performing the procedure. Moreover, due to special objectives in the intra-operative setting, the situation cannot be compared with standard radiological image acquisition...

CASE: We describe 2 patients with nonunion of the clavicle and dynamic compression of the subclavian artery. In both patients, no structural abnormality of the subclavian vessels was evident at rest; however, with the arm in hyperabduction, arterial occlusion occurred because of the mobility of the fracture and a prominent callus. CONCLUSION: This small case series demonstrates an important and, to our knowledge, unreported clinical complication of clavicle fracture nonunion...

The use of mobile technologies in medicine, or mHealth, holds promise to improve health worker (HW) performance, but evidence is mixed. We conducted a cluster-randomized controlled trial to evaluate the effect of text message reminders to HWs in outpatient health facilities (HFs) on quality of care for malaria, pneumonia, and diarrhea in Malawi. After a baseline HF survey (2,360 patients) in January 2015, 105 HFs were randomized to three arms: 1) text messages to HWs on malaria case management; 2) text messages to HWs on malaria, pneumonia, and diarrhea case management (latter two for children < 5 years); and 3) control arm (no messages)...

BACKGROUND: Post-thrombotic obstruction can be adequately treated by percutaneous transluminal angioplasty and stenting. This procedure is rapidly emerging as a minimally invasive alternative to traditional open surgical operations. However, the patient will be exposed to a significant amount of radiation during preoperative planning and operation. The aim of this study was to evaluate the amount of radiation exposure to patients during venous recanalization. METHODS: All patients undergoing endovenous recanalization from February 2016 to February 2018 were included in this study...

Benign portal vein stenosis is a rare complication following pancreaticoduodenectomy. Because a direct surgical approach to the portal vein is difficult due to severe adhesions following pancreaticoduodenectomy, portal vein stent placement is considered a good treatment option. Herein, we report 3 cases of severe portal vein stenosis following pancreaticoduodenectomy that were treated with portal venous stent placement in a hybrid operating room, combining a conventional operating room with an angiography suite...
