Fair division algorithms, especially the ones that require continuous observation, tend to assume synchronicity in decision making and knife movements in theory. However, in practice, it is not always possible to give an exact solution to a fair division algorithm without making some assumptions or error bounds. As such, we would like implement both an exact and discrete solution to given algor...

PURPOSE Gamma Knife radiosurgery is a highly precise and accurate treatment technique for treating brain diseases with low risk of serious error that nevertheless could potentially be reduced. We applied the AAPM Task Group 100 recommended failure modes and effects analysis (FMEA) tool to develop a risk-based quality management program for Gamma Knife radiosurgery. METHODS A team consisting o...

Sir,?I must plead guilty to having performed many iridectomies unintentionally, and at the same time point out the cause of this little accident in most of my cases. This was a "bellying" of the blade of the Grafe's knife. If instead of the knife being, except at the point, of equal thickness and width there be a " belly " or greater width in the forepart of the blade, leaving the part near the...

We reported a young male with knife assault to his chest. He was transferred to the hospital without manipulating the knife. He was completely conscious and had sinus tachycardia and regular breathing. Emergency thoracotomy was performed and the knife was removed. No organ was damaged. This case presentation showed that in this kind of trauma, it is mandatory not to manipulate the penetrating f...

PURPOSE To evaluate intracranial control after surgical resection according to the adjuvant treatment received in order to assess the optimal radiotherapy (RT) dose and volume. MATERIALS AND METHODS Between 2003 and 2015, a total of 53 patients with brain oligometastases from non-small cell lung cancer (NSCLC) underwent metastasectomy. The patients were divided into three groups according to ...

INTRODUCTION No national recording systems for knife injuries exist in the UK. Understanding the true size and nature of the problem of knife injuries is the first stage in reducing the burden of this injury. The aim of this study was to survey every knife injury seen in a single inner city emergency department (ED) over a one-year period. METHODS A cross-sectional observational study was per...
