Review Meta Analysis
Risk factors for surgical site infection following spinal surgery: A meta-analysis.
Surgical-site infection (SSI) after spinal surgery is the most common complication, which results in greater morbidity, mortality, and health care costs. Identifying risk factors of SSI is an important point for preventive strategies to reduce the incidence of SSI. The aim of this meta-analysis is to investigate the most important risk factors for SSI after spinal surgery. ⋯ Diabetes, prolonged operative times (>3 hours), body mass index more than 35, posterior approach, and number of intervertebral levels (≥7) are associated with an increased risk of SSI after spinal surgery. Almost all these risk factors are in line with the known risk factors for SSI in patients who underwent spinal surgery.

Vitamin D deficiency is a relatively common occurrence in patients presenting for spinal surgery; however, whether this abnormality has any effect on spinal fusion outcomes remains unclear. We performed a systematic review of the available literature relevant to the association between vitamin D deficiency and spinal fusion outcomes. ⋯ The literature suggests that patients presenting for spinal fusion may benefit from correction of vitamin D deficiency to maximize the chance of a successful arthrodesis and to achieve optimal surgical outcomes. Future prospective studies are needed to determine whether routine preoperative treatment of this metabolic derangement is warranted.

Ectopic Suprasellar Thyrotropin-Secreting Pituitary Adenoma: Case Report and Literature Review.
Ectopic thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are rare and can often be misdiagnosed as primary hyperthyroidism. We present a case of an ectopic suprasellar TSH-secreting pituitary adenoma. A literature review of previously reported ectopic TSH-secreting and suprasellar pituitary adenomas is included to illustrate the clinical characteristics of this disease entity and the diversity of operative approaches to treating ectopic suprasellar pituitary adenomas. ⋯ To the best of our knowledge, this is the first reported case of an ectopic suprasellar TSH-secreting pituitary adenoma. Preoperative preparation and complete resection are the keys to a cure. The extended endoscopic endonasal transtuberculum sellar approach is an alternative minimally invasive method for the removal of an ectopic suprasellar pituitary adenoma.

Review Historical Article
Neurocritical Care in China: Past, Present, and Future.
Despite the lack of resources and materials, there has been an increasing demand for acute neurologic care owing to the heavy burden of neurocritical illness in most developing countries, including China, where the morbidity and mortality of severe neurologic and neurosurgical disorders remains high. Neurointensive care units did not start appearing in China until the late 1980s. Although great progress has been made over the past 2 decades in the establishment of equipped neurocritical care centers, advancements in medical infrastructure, streamlining of resident training programs, and implementation of multidisciplinary care teams, there remain areas that warrant improvement to care for our growing patient population. Here we review and discuss the history, present state, and future of neurocritical care in the People's Republic of China.

Bilateral segmental agenesis of the internal carotid artery is a rare congenital anomaly. We present a case of bilateral internal carotid artery segmental agenesis in an asymptomatic 18-year-old man. Embryology, common collateral pathways, clinical presentation, and clinical importance of this condition are discussed. According to our review of the literature, this report is the first to describe bilateral internal carotid artery segmental agenesis in a patient studied with magnetic resonance imaging, computed tomography, Doppler ultrasonography, and digital subtraction angiography. ⋯ Bilateral segmental agenesis of internal carotid artery may be completely asymptomatic and harmless, but associated conditions, such as cerebral aneurysms or abnormal collateral circulation, should alert clinicians to the possibilities of subarachnoid hemorrhage or cerebral ischemia.
