Multicenter Study Comparative Study
Comparisons of 30-day mortalities and 90-day functional recoveries after first and recurrent primary intracerebral hemorrhage attacks: a multiple-institute retrospective study.
The aim of this study was to determine and compare 30-day mortalities and 90-day functional recoveries after first and recurrent primary intracerebral hemorrhage (PICH) attacks. The investigators sought to identify factors predisposing 30-day mortality and functional recovery and to compare patients after first and recurrent PICH attacks. ⋯ The factors found to predispose clinical outcome were similar in the two groups. This study shows that given optimal treatment, recurrent PICH patients can achieve the same clinical outcomes as first PICH patients.

To identify the specific angioarchitectural characteristics of arteriovenous malformations (AVMs) that are associated with a clinical presentation of nonhemorrhagic neurologic deficits. ⋯ The characteristics of AVM associated with nonhemorrhagic neurological deficits include female sex, deep AVM location, more than three arterial feeders, only perforating feeding artery, more than three draining veins, the presence of varices in the venous drainage, and a Spetzler-Martin grade of III to V.

Case Reports
Atypical presentation of primary central nervous system non-Hodgkin lymphoma in immunocompetent young adults.
Primary central nervous system non-Hodgkin lymphoma (PCNSL) is a malignant lymphoma limited to the cranial-spinal axis in the absence of systemic lymphoma. Historically, PCNSL accounts for fewer than 5% of all cases of primary intracranial neoplasms. PCNSL is rare in immunocompetent young adults. Although the prognosis for PCNSL is poor, approximately 20%-30% percent of cases achieve a cure. ⋯ To our knowledge, this is the first report of primary CNS lymphoma of the choroid plexus and septum pellucidum in otherwise healthy, immunocompetent young adults.

To understand better the scope of wrong-level lumbar spine surgery and current practices in place to help avoid such errors. ⋯ There is substantial heterogeneity in approaches used to localize operative levels in the lumbar spine. Existing safety protocols may not be mitigating wrong-level surgery to the extent previously thought.

The purpose of this study is to investigate trends in the incidence of subarachnoid hemorrhage (SAH) in South Korea from 2006-2009. ⋯ The age-adjusted incidence rates of SAH were slightly decreased in South Korea. Further research should be conducted to identify the clinical risk factors to reduce SAH incidence rates even more, especially in younger people.
