The primary purpose of the study was to investigate the psychosocial effects of harboring a known but untreated unruptured intracranial aneurysm (UIA), information considered important to the decision of whether to treat or not treat an unruptured aneurysm. ⋯ A decrease in overall quality of life was found to be associated with harboring an identified but untreated UIA. Findings from the current study suggest that further investigation of psychosocial outcome in other groups of untreated UIA patients is warranted. Results also suggest that some untreated UIA patients might benefit from psychological intervention.

Comparative Study Clinical Trial
Detection of root avulsion in the dominant C7 obstetric brachial plexus lesion: experience with three-dimensional constructive interference in steady-state magnetic resonance imaging and electrophysiology.
Preoperative, reliable detection by ancillary investigations of spinal nerve root avulsions in infants with severe obstetric brachial plexus lesions to avoid ineffective operative repair from deceivingly intact but actually avulsed nerve roots. ⋯ 3D CISS MRI provides good images of anterior and posterior spinal roots in infants with obstetric brachial plexus lesions. Images seem to allow accurate prediction of root avulsion in the majority of patients. In this study, electrodiagnostics were of limited value.

Comparative Study
Nausea and dizziness after vestibular schwannoma surgery: a multivariate analysis of preoperative symptoms.
Nausea and dizziness are very discomforting for patients after vestibular schwannoma surgery and they impair recovery. ⋯ It is possible to identify patients with a higher risk of postoperative nausea and dizziness after vestibular schwannoma surgery. This allows one to inform these patients preoperatively and to initiate an early postoperative drug therapy to ease their symptoms.

Comparative Study
Atlantoaxial rotatory fixation: part 2--new diagnostic paradigm and a new classification based on motion analysis using computed tomographic imaging.
This is Part II of a study on atlantoaxial rotatory fixation (AARF) that aims to introduce a new diagnostic paradigm and a new classification of this condition based on motion analysis of C1C2 rotation using computed tomographic (CT) imaging. This phase of the study is possible because Part I succeeded in defining physiological C1C2 axial rotation with CT data from 21 normal children, displayed in a highly concordant composite motion curve, which is used as the normal template for the present study. AARF is defined as flagrant departure from normal motion dynamics as delineated by abnormal motion curves. The new classification is predicated on the graded amount of pathological stickiness in the restricted rotation. ⋯ AARF can be reliably diagnosed with a simple and practical CT protocol and construction of a three-point motion curve superimposed on a reusable normal template. The type of AARF, reflective of the severity of pathological stickiness of rotation, can be identified readily by the shape of the motion curve. This system of classification is useful in selecting the best regimen of management.

Comparative Study
Rapid administration of antifibrinolytics and strict blood pressure control for intracerebral hemorrhage.
Hematoma growth is a major cause of poor outcome in patients with intracerebral hemorrhage. We evaluated the efficacy of a combination of rapid antifibrinolytic therapy and strict blood pressure control for prevention of hematoma growth in this retrospective study. ⋯ The combination of rapid administration of antifibrinolytics and strict blood pressure control may prevent hematoma growth in patients with intracerebral hemorrhage.
