Considerable effort has been made in order to reduce surgical invasiveness while maintaining optimal exploiting of the operative space in aneurysm surgery. One aspect of this evolution is represented by the Lazic (Peter Lazic GmbH, Tuttlingen, Germany) aneurysm clip system. The purpose of this study was to illustrate the new generation clip system in practiced aneurysm surgery. ⋯ The new D-Clip system combines an attenuated design for minimally invasive clipping procedures with traditional mechanisms of common clip systems. It therefore appears to be highly versatile in the context of variable different aneurysm morphologies and locations while maintaining high standard surgical safety and efficacy.

Juxtafacet cysts (JFCs) include both synovial and ganglion cysts adjacent to a spinal facet joint or arising from the ligamentum flavum of the spinal facet joints. Various treatments have been proposed; however, a surgical approach appears to be most effective. The aim of this study was to review patients with lumbar JFCs treated using a full endoscopic approach and elaborate the details of the surgical routes and techniques and their merits and pitfalls. ⋯ JFCs could be effectively treated by full endoscopic surgery. The type of approach should be based on the anatomic site of the lesion and the condition of the patient. The interlaminar approach is appropriate for cysts located in the lower segment with larger interlaminar space. The transforaminal or transfacet approach is preferred for patients for whom general anesthesia is a high risk.

Case Reports
Reversible, position-dependent midbrain compression in a patient with spontaneous intracranial hypotension.
Intracranial hypotension is an underrecognized cause of spontaneous subdural hematoma. Failure to identify this entity and treat the underlying etiology can result in profoundly dangerous clinical consequences, prolonged and costly hospitalization, and caregiver fatigue, as seen in the case presented here. ⋯ This case demonstrates the importance of considering intracranial hypotension in cases of positional herniation syndrome and the necessity for early and aggressive attempts at identifying and treating the underlying cause to prevent unnecessary neurologic dysfunction and protracted medical care.

The Role of Flexible Neuroendoscopy in Spinal Neurocysticercosis: Technical Note and Report of 3 Cases.
Neurocysticercosis, caused by the larval form of the tapeworm Taenia solium, is the most common parasitic disease affecting the human central nervous system. The incidence of spinal neurocysticercosis in endemic regions ranges from 0.25% to 5.85%. Surgery is preferred when medical treatment fails to achieve control of the symptoms or when multiple cysts are present. ⋯ Flexible spinal endoscopy is a feasible and valuable tool in patients with spinal neurocysticercosis that do not respond adequately to standard treatment. It helps restore cerebrospinal fluid dynamics and can be used to place shunt catheters under guided vision. Longer endoscopes are needed to explore the entire spinal subarachnoid space with a single approach, and more research in this area is needed.

In patients with traumatic brain injury (TBI), whether sleep disorder is associated with disturbances in molecular rhythmicity is unclear. This study aimed to investigate the relationship between abnormal sleep and regulation by circadian rhythms in patients with TBI. ⋯ Abnormal expression levels of Per2, Clock, and Bmal1 were detected in patients with TBI-related sleep disorders. These novel findings demonstrate disturbances in the molecular clock in TBI patients and have important implications for our understanding of the aberrant rhythms reported in this disease.
