The Position and orientation accuracy of robot manipulator has long become a major issue to be considered in its advanced application. The simplified expressions for the differential vector of the end-effector have been proposed based on the original expressions derived by Veitschegger and Wu in 1986. According to this new expression, a linear error model that described the end-effector positio...

purpose: to assess the efficacy and safety of laser in situ keratomileusis (lasik) for correction of residual myopia and astigmatism after penetrating keratoplasty (pk). methods: in this prospective interventional case series, lasik was performed on 14 eyes of 13 patients unable to wear glasses or contact lenses after pk. the interval between lasik and pk was at least one year. all patients had...

purpose: to study the validity and reliability of subjective refraction, predicted phoropter refraction (ppr) measured by zywave aberrometer, and final surgical plan applied for laser vision correction. methods: this prospective study was conducted on 94 myopic or myopic astigmatic eyes (48 patients) who were candidates for refractive surgery in negah eye hospital from april 2012 to july 2012. ...

BACKGROUND Dolphin® visual treatment objective (VTO) prediction software is routinely utilized by orthodontists during the treatment planning of orthognathic cases to help predict post-surgical soft tissue changes. Although surgical soft tissue prediction is considered to be a vital tool, its accuracy is not well understood in tow-jaw surgical procedures. The objective of this study was to quan...

PURPOSE To determine the reproducibility and accuracy of ultrasonographic (US) measurements of distances between the corneoscleral limbus and the insertion site of the medial (MR) or lateral rectus (LR) muscle compared with intraoperative measurements in patients with strabismus. METHODS One eye in each of 17 patients with postoperative secondary strabismus caused by over- or undercorrected e...

We evaluated a neural network model for prediction of glucose in critically ill trauma and post-operative cardiothoracic surgical patients. A prospective, feasibility trial evaluating a continuous glucose-monitoring device was performed. After institutional review board approval, clinical data from all consenting surgical intensive care unit patients were converted to an electronic format using...

A surgical complication is any undesirable and unexpected result of an operation. Surgical complications could be fatal to a patient if they are not detected earlier. One the factors that affect severity time between patient's diagnosis surgery. The might at risk doctor misdiagnoses them or concludes has no severe symptoms. This paper aims study correlation post-surgical conditions & durati...

BACKGROUND Minimally invasive surgical approaches are widely used for total hip arthroplasty (THA). However, potential problems related to a reduced visual field during surgery, such as implant malposition, neurovascular injury, and poor implant fixation, have been reported. In these situations, a shorter stem is easier to insert in the femoral canal. To evaluate the accuracy of shorter stem or...

Background: Quality assurance and peer-review practices in surgical pathology have been well described in the literature, but the majority of these reports apply to the realm of general surgical pathology. We focused on the peer-review reporting system of a specialty women’s health pathology practice consisting exclusively of breast and gynecologic pathology, with the specific aims of identifyi...
