Multicenter Study Comparative Study
Patterns of stroke between university hospitals and non-university hospitals in mainland China: a prospective multicenter hospital-based registry study.
In China, stroke has risen to the first commonest cause of death. Currently published data on stroke come mainly from university hospitals and less from community hospitals, especially lacking information on stroke focusing on the differences between university hospitals and nonuniversity hospitals. Therefore we aimed to investigate the patterns and differences of acute stroke between university hospitals and nonuniversity hospitals in China. ⋯ This survey comparing stroke patients treated in university and nonuniversity hospitals in China showed that both cohorts were largely comparable including most demographic features, such as age and gender, history of stroke, and stroke subtypes. It may be concluded that patient cohorts treated on stroke units in university and nonuniversity hospitals are similar and stroke units in both types of institutions are also comparable in terms of workload and most patient outcomes.

Review Case Reports
Calcifying Pseudoneoplasm of the Neuraxis Arising from the Sacral Canal: A Case Report and Review of the Literature.
Calcifying pseudoneoplasm of the spine is an extremely rare lesion and has not yet been reported in the sacral canal. ⋯ Calcifying pseudoneoplasm of the neuraxis can occur throughout the spine, including the sacral canal, and should be included in the differential diagnosis of intraspinal calcified lesions.

Multicenter Study Comparative Study Clinical Trial
Efficacy and Safety of Treatment of Ruptured Intracranial Aneurysms.
To compare the treatment results of ruptured aneurysms treated endovascularly with aneurysms treated with microsurgical clipping. ⋯ Microsurgical clipping shows a lower rate of treatment-associated complications and a higher occlusion rate of ruptured intracranial aneurysms than coil embolization. The individual evaluation and decision process for choice of treatment modality in this study is very effective.

Synchronous tumors of the cerebellopontine angle (CPA) are very rare and inconsistently described. We present 2 cases of contiguous vestibular schwannoma (VS) and meningioma and a systematic literature review of all multiple CPA tumors. ⋯ Multiple CPA tumors are rare, heterogeneous lesions with a marked predisposition toward poor facial nerve outcomes, potentially attributable to a paracrine mechanism that simultaneously drives multiple tumor growth and increases invasiveness or adhesiveness at the facial nerve-tumor interface. Preceding nomenclature has been confounding and inconsistent; we recommend classifying all multiple CPA tumors as "synchronous tumors," with "schwannoma with meningothelial hyperplasia" or "tumor-to-tumor metastases" reserved for rare, specific circumstances.
