Case Reports
Endoscopic-Assisted Microsurgical Resection of a Recurrent Conus Medullaris Dermoid Tumor.
Surgery for intramedullary spinal cord tumors presents multiple unique challenges, including the need to operate through a very narrow myelotomy window. In this operative video, we demonstrate the use of the surgical endoscope in an operation performed on a 35-year-old woman. ⋯ After consenting to surgery, she underwent reoperative posterior lumbar approach to resection of her tumor. In our video we demonstrate our use of a surgical endoscope, which allowed us to minimize the extent of our myelotomy and resect tumor rostral and caudal to our myelotomy, thus minimizing the risk of damage to normal spinal cord that is displaced by tumor (Video 1).

The far lateral approach provides wide surgical access to the lower third of the clivus, pontomedullary junction, and anterolateral foramen magnum and rarely requires craniovertebral fusion. The most common indications for this approach are posterior inferior cerebellar artery and vertebral arteryaneurysms, brainstem cavernous malformations, and tumors anterior to the lower pons and medulla, including meningiomas of the anterior foramen magnum, schwannomas of the lower cranial nerves, and intramedullary tumors at the craniocervical junction. We provide a stepwise description of how we perform the far lateral approach, as well as how to combine the far lateral approach with other skull base approaches, including the subtemporal transtentorial approach, for lesions involving the upper clivus; the posterior transpetrosal approach, for lesions involving the cerebellopontine angle and/or petroclival region; and/or lateral cervical approaches, for lesions involving the jugular foramen or carotid sheath regions.

Review Meta Analysis
Recurrent Cushing's disease: An extensive review on pros and cons of different therapeutic approaches.
Recurrent Cushing disease (CD) is characterized by the reappearance of clinical and hormonal aspects of hypercortisolism that occur more than 6 months after an initial post-treatment remission. ⋯ Compared MT and TSS, RT has a statistically lower rate of remission. Although there is robust superiority of surgery over RT, interpretation of MT data must considered with caution due to the small number of included cases and wide CI range.

Randomized Controlled Trial
The outcomes of combined endoscopic surgery and fibrinolytic treatment protocol for intraventricular hemorrhage: a randomized controlled trial.
Intraventricular fibrinolysis (IVF) and endoscopic surgery (ES) are the new promising treatment strategies to enhance the rate of hematoma clearance, which might improve functional outcome. This study investigated and compared the outcomes among these interventions. ⋯ This study demonstrated that combined ES and IVF is safe and effective for the treatment of IVH. In addition, it concluded that aggressive but safe procedures used to remove IVH could improve clinical outcome in patients with IVH.

Multicenter Study
The safety of spine surgery in the late-stage elderly of 75 years of age or older: A retrospective multicenter study.
The objective of this study was to verify that spine surgery for late-stage elderly (LSE) (age 65-74 years) is as safe as that for early-stage elderly (ESE) (age 65-74 years). ⋯ Spine surgery even for LSE can be safely done, if perioperative risk factors are appropriately managed.
