Influence of the T1-slope on sagittal alignment of the subaxial cervical spine after posterior atlantoaxial fusion in os odontoideum.
To analyze the effect of T1-slope (T1S) on sagittal alignment of the subaxial cervical spine after posterior C1-C2 fusion. ⋯ T1S was a useful parameter to evaluate postoperative alignment of the subaxial cervical spine after posterior C1-C2 fusion. To avoid postoperative misalignment of the subaxial cervical spine, C1-C2 should be fixed in less lordosis, especially in patients with high preoperative T1S.

Multicenter StudyIntracranial angiomatous meningiomas: A 15-year, multicenter study.
Angiomatous meningiomas (AMs) represent a rare subtype of meningiomas in which the vascular component prevail. They represent less than 1% of all intracranial tumors and approximately 2.1% of all meningeal tumors (Hasselblatt et al., 2004). The purpose of this study was to determine the clinical characteristics, radiological features and prognosis of AMs based on a Tunisian multicenter experience in the management of 58 successive cases of intracranial AMs. To the best of our knowledge, this is the largest series reported to date. ⋯ AMs represent a rare subtype of meningioma characterized by variable cystic components, large peritumoral edema and multiple areas of vascular signal voids. The mainstay of the treatment is gross total resection, ideally following a preoperative embolization. The fate of the tumor remnant after incomplete tumor resection still needs to be evaluated and we do not recommend the systematic use of post-operative adjuvant RT in all cases. As local recurrence can develop many years after initial treatment, Long-term follow-up is mandatory.

Predictors of 30-day perioperative morbidity and mortality of unruptured intracranial aneurysm surgery.
Large-scale studies examining the incidence and predictors of perioperative complications after surgical clipping of unruptured intracranial aneurysms (UIA) using nationally representative prospectively collected data are lacking in the literature. ⋯ Our study yields morbidity and mortality benchmarks for UIA surgery in a representative, national surgical registry. It will hopefully aid in recognizing those patients at greater risk for postoperative complications following surgical management, leading to appropriate changes in treatment strategies for this selected group of patients.

Options in treating trigeminal neuralgia: Experience with 195 patients.
For patients with medically unresponsive trigeminal neuralgia (TN), surgical options include microvascular decompression (MVD), radiofrequency rhizotomy (RF), and stereotactic radiosurgery (SRS). In an attempt to identify the risks and benefits and cost inherent with each of the three modalities, we performed a retrospective review of our experience with 195 cases of TN treated over the past 15 years. ⋯ MVD for TN is the treatment least likely to fail or require additional treatment. Patients who underwent MVD were younger than those undergoing RF or SRS. The highest rate of recurrence of TN was encountered in patients undergoing RF (64%). Facial numbness was least likely to occur with MVD (16%) compared to RF and SRS (50% and 36% respectively).

Familial occurrence of headache disorders: A population-based study in mainland China.
Headache disorders are highly prevalent worldwide, and familial occurrence and heredity are contributory factors attracting the interest of epidemiological researchers. Our purpose, in a large sample drawn nationwide from the Chinese general population, was to evaluate the frequency of similar headache in first-degree relatives (FDRs) of those with different headache types. ⋯ Headache was highly prevalent in China and common among FDRs of those with any type of headache (headache on ≥15 days/month>migraine>TTH). Against the background of the general-population prevalence of each disorder, familial occurrence was a very highly influential factor in headache on ≥15 days/month. There are important implications in this for public health and education.
