Aripiprazole for prevention of delirium in the neurosurgical intensive care unit: a double-blind, randomized, placebo-controlled study.

Purpose: Delirium is reported in over 50% of critically ill ICU patients, and is associated with increased mortality and long-term cognitive consequences. Prevention and early management of delirium are essential components of ICU care. However, pharmacological interventions have not been effective in delirium prevention.

Feasibility and Data Quality of the National Spinal Cord Injury Registry of Iran (NSCIR-IR): A Pilot Study.

Background: Spinal cord injury (SCI) is one of the most disabling consequences of trauma with unparalleled economic, social, and personal burden. Any attempt aimed at improving quality of care should be based on comprehensive and reliable data. This pilot investigation studied the feasibility of implementing the National Spinal Cord and Column Injury Registry of Iran (NSCIR-IR) and scrutinized the quality of the registered data.

Intradiploic dermoid cyst: a rare cause of intracranial hypertension.

In this study, we report a rare case of intradiploic dermoid cyst in a patient who developed rapid symptoms of intracranial hypertension (ICH) that mimicked Pseudotumor cerebri syndrome clinically. A 25-year-old female presented with a history of headache, nausea, vertigo and blurred vision in the past 4 months. Images revealed a small supratentorial extradural intradiploic tumor.

Variations in the Anatomy of the Willis' circle: A 3-year cross-sectional study from Iran (2006-2009). Are the distributions of variations of circle of Willis different in different populations? Result of an anatomical study and review of literature.

Background: It is not well known whether the distributions of variations of circle of Willis (CW) are different in different populations. Previous studies have indicated: (a) The variations of the structure of the CW in different populations and ethnic and (b) some correlation between those congenital anatomical variations and possible cerebrovascular diseases. The frequency of such anatomical variations has not been evaluated sufficiently in the Iranian population.
