Review Meta AnalysisThe Cerebrovascular Response to Ketamine: A Systematic Review of the Animal and Human Literature.
The aim of the study was to perform a systematic review of the literature on the cerebrovascular/cerebral blood flow (CBF) effects of ketamine in both animal and human subjects. ⋯ Animal models indicate an increase in global CBF and rCBF with ketamine administration, with a trend to vasodilation of medium-sized intracranial vessels through a calcium-dependent mechanism. Human studies display an Oxford 2b, Grading of Recommendation Assessment Development and Education C, level of evidence to support a trend to increased global CBF and rCBF with ketamine administration in both healthy volunteers and elective surgical patients without neurological illness.

Association of Hemodynamic Factors With Intracranial Aneurysm Formation and Rupture: Systematic Review and Meta-analysis.
Recent evidence suggests a link between the magnitude and distribution of hemodynamic factors and the formation and rupture of intracranial aneurysms. However, there are many conflicting results. ⋯ Pooled analyses of computational fluid dynamics models suggest that an increase in WSS and gradient oscillatory number may contribute to aneurysm formation, whereas low WSS is associated with ruptured aneurysms. The location of the aneurysm at the bifurcation or sidewall may influence the correlation of these hemodynamic factors.

Meta-analysis of antegrade continence enema in adults with faecal incontinence and constipation.
Faecal incontinence and constipation affects up to 20 per cent of the general population, and can be a significant source of distress. The antegrade continence enema (ACE) procedure has been shown to be an effective alternative treatment option for children, but its use in adults requires clarification. A systematic review and meta-analysis was performed to determine outcomes of the ACE procedure in adults with faecal incontinence and constipation. ⋯ The ACE procedure is an effective long-term treatment option in patients with faecal incontinence and constipation, and should be considered before performing a definitive colostomy. Patients with faecal incontinence appear to respond better than those with constipation.

Renaissance Neurosurgery: Italy's Iconic Contributions.
Various changes in the sociopolitical milieu of Italy led to the increasing tolerance of the study of cadavers in the late Middle Ages. The efforts of Mondino de Liuzzi (1276-1326) and Guido da Vigevano (1280-1349) led to an explosion of cadaver-centric studies in centers such as Bologna, Florence, and Padua during the Renaissance period. ⋯ With increased understanding came new techniques to address various neurosurgical problems from skull fractures to severed peripheral nerves. The present study aims to review the major developments in Italy during the vibrant Renaissance period that led to major progress in the field of neurosurgery.

To describe studies evaluating 3 generations of three-dimensional (3D) displays over the course of 20 years. ⋯ Individual laparoscopic performance in 3D may be affected by a multitude of factors. It is crucial for studies to measure participant stereoscopic ability, control for system crosstalk, and use validated measures of performance.
