Concerns of rising healthcare costs and the ever increasing desire to improve surgical outcome have motivated the development of a new robotic assisted surgical procedure for the implantation of artificial hearing devices (AHDs). This paper describes our efforts to enable minimally invasive, cost effective surgery for the implantation of AHDs. We approach this problem with a fundamental goal to...

Abstract Aim Surgical simulators equipped with artificial intelligence (AI) systems provide risk-free training on realistically simulated complex patient cases, objective performance assessment, and tailored error avoidance feedback. This study compared the efficacy of real-time AI instruction human instructor-mediated in surgical technical skills teaching. Method Medical students (n = 98) were...

the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...

Purpose: We evaluated the effect of myopia on lateral rectus recession in children with intermittent exotropia.Methods: Medical records patients mild to moderate who underwent for exotropia surgery were retrospectively reviewed. Patients grouped into three groups according their spherical equivalents (SEs) (group 1: SE > -1.0 diopter [D]; group 2: -3.0 D ≥ D; 3: ≤ D). The success rate after ...

Background Medical error in trauma care remains common [1]. Checklists are a cognitive aid that can be employed to standardise practice and minimise error. Their usage is ubiquitous in other high-intensity professions, such as aviation. Following the success of the World Health Organisation's surgical safety checklist they are now in the process of developing a trauma care checklist. My aim was...

Electromagnetic tracking (EMT) is used in several medical fields to determine the position and orientation of dedicated sensors, e.g., attached to surgical tools. Recently, EMT has been introduced to brachytherapy for implant reconstruction and error detection. The manuscript briefly summarizes the main issues of EMT and error detection in brachytherapy. The potential and complementarity of EMT...

A closed-form expression and an upper bound are obtained for the mean absolute error of the unbiased estimator of a probability in inverse binomial sampling. The results given permit the estimation of an arbitrary probability with a prescribed level of the normalized mean absolute error.

OBJECTIVE Knowledge of sampling errors is essential for correctly interpreting the results from household surveys and evaluating their sampling designs. The composition of household samples used in surveys gives rise to situations of complex estimation. In this light, the study was conducted with the aim of evaluating the performance of the variance estimators in surveys carried out among urban...
