Diffuse axonal injury (DAI) is a common form of primary head injury. This study was done to see the association of DAI grades with extended Glasgow Outcome Scale (GOSE). ⋯ Mean GCS at presentation is a better predictor of outcome after DAI rather than its grade.

Chiari malformations include a large spectrum of anomalies of hindbrain formation that appear at different stages of development of the central nervous system. Chiari described these malformations as congenital anomalies of the hindbrain characterized by downward elongation of the brain stem and cerebellum into the cervical portion of spinal cord. Much research regarding Chiari malformation I (CMI) has focused on the cerebrospinal fluid (CSF) dynamics rather than the anatomic relationships of the tonsils and brainstem. The aim of the present study was to measure the peak CSF velocity at the foramen magnum and record the changes after foramen magnum decompression in patients with CMI aged <18 years. ⋯ Decompression of the foramen magnum was associated with decreased CSF peak velocity in patients with CMI.

Observational Study
Findings and prognostic value of contrast enhanced early MRI after coil embolization of cerebral aneurysms.
Recent studies imply an association between aneurysm wall enhancement (AWE) on contrast-enhanced magnetic resonance imaging and aneurysm rupture. We investigated the prevalence and clinical significance of AWE and enhancement within the aneurysm (inner enhancement [IE]) in coiled aneurysms. ⋯ AWE after coil embolization cannot be used for recurrence risk stratification owing to its high prevalence. IE is likely to represent contrast inflow in the coiled aneurysm.

To investigate preoperative baseline anemia, stratified by severity as a function of hematocrit level, as a risk factor for perioperative complications in geriatric patients undergoing spinal procedures. ⋯ This study indicated that patients with preoperative baseline anemia were at risk for requiring transfusions, renal failure, and infectious complications. Physicians should be cognizant of anemia as a risk factor affecting numerous perioperative complications and adverse outcomes to work toward improving health-related quality of life.

To describe the morphology and anatomical relationship of the jugular process (JP) and to elucidate its utility as a surgical landmark in the lateraland posterior lateral approaches to the jugular foramen. ⋯ The JP is an important surgical landmark in the identification of jugular foramen, especially in the lateral and posterior approaches. A better understanding of its morphology and its relationship with the surrounding structures is a prerequisite for accurate surgical planning and intraoperative orientation.
