The initial stage of neurosurgery in China: Contributions from Peking Union Medical College Hospital.
Modern neurosurgery has been developing worldwide for more than a century, whereas in China, as stated in previous literature, only 7 decades have passed since the development of neurosurgery during the early 1950s after World War II and China's War of Liberation. However, as increasing evidence before the wars from medical records, annual hospital reports, and journal archives emerge, the history of neurosurgery in China, especially the initial stage, needs to be reassessed. The establishment of the Peking Union Medical College Hospital (PUMCH) in 1921, funded by the Rockefeller Foundation, marked the start of Western medicine in China. ⋯ D. and Yi-Cheng Zhao, M. D., both of whom graduated from PUMC and received further training abroad, made great contributions to the initial growth of Chinese neurosurgery. Although neurosurgery experienced slow and even stagnant development in China during the wars that took place from 1941-1949, the prewar period from 1921-1940 witnessed substantial improvement in operative skills, bedside education, resident training, and scientific research in neurosurgery at PUMCH, providing indispensable contributions that have allowed Chinese neurosurgery to flourish during the past 7 decades.

Long-standing overt ventriculomegaly in adults (LOVA) is form of hydrocephalus that develops during childhood, manifesting its symptoms during adulthood. Only a small number of LOVA case series have been published, and controversies regarding optimal management still exist. The authors collected a series of symptomatic LOVA patients treated successfully using endoscopic third ventriculostomy (ETV), aiming to strengthen what has been reported in the literature on ETV's role in both neurologic and neurocognitive outcomes. ⋯ LOVA is a form of hydrocephalus that must be correctly identified. A correct magnetic resonance study and comprehensive neuropsychologic assessment are crucial to identify it in order to define proper management. From our analysis, ETV represents the gold standard treatment granting rewarding results that are maintained in a long-term follow-up.

Randomized Controlled Trial
Application of Midazolam Injection in Patients with Intraoperative Nerve Block Anesthesia and Sedation Assisted by Imaging Guidance.
In the present study, we explored the clinical effect of midazolam as an adjuvant analgesic and tranquilizer after brachial plexus block anesthesia with the aid of imaging guidance. ⋯ The ultrasound-guided inferior intermuscular sulcus approach for brachial plexus block is suitable for unilateral upper extremity radial hand surgery. For surgery involving the upper extremity ulnar hand side, a larger dose (concentration) of local anesthetic should be used within a safe range and/or an additional ulnar nerve block might be necessary. Midazolam adjuvant medication can have a good sedative and amnestic effect in brachial plexus block anesthesia, helping to reduce pain and inhibit the increase in stress levels.

To present the outcomes of endoscopic endonasal surgery for giant pituitary adenomas and discuss the extent of resection to minimize morbidity and mortality. ⋯ Long-term follow-up results and low recurrence rate of tumors indicate that RR is effective to decrease morbidity and mortality.

Primary central nervous system lymphoma (PCNSL) is a rare manifestation of aggressive extranodal non-Hodgkin lymphoma. In patients with deep-seated lesions, stereotactic brain biopsy (SBB) is an accepted diagnostic procedure to obtain histopathologic confirmation. ⋯ In suspected cases of PCNSL, a histopathologic diagnosis is necessary to distinguish it from glioblastoma or other, nonmalignant conditions. Deep-seated PCNSLs present a higher risk of biopsy-related morbidity and mortality. Intraoperative frozen section increases the diagnostic yield and reduces the number of sampling procedures. Postoperative computed tomography seems to be warranted in patients with suspected PCNSL.
