Child abuse with sewing needle is a rare but well-known homicide attempt threatening the life of victims. Information about diagnosis and treatment of such cases either in the acute or chronic phases is lacking and ambiguous in the literature. This study intends to report the experience of 6 victims of homicide attempt who presented to the authors in different decades of life and were managed in different ways. This may deliver some evidences to the literature regarding management of further cases encountered by neurosurgeons. ⋯ In spite of standard algorithms proposed for management of penetrating head wounds, selection of the best treatment in the victims harboring sewing needles in their brain needs close cooperation between neurosurgeons, pediatricians, psychiatrists, and social workers. Furthermore, there is no absolute indication for removing sewing intracranial needles detected in the later decades of life.

Comparative Study
Comparison of postoperative cognitive function in patients undergoing surgery for ruptured and unruptured intracranial aneurysm.
Patients with SAH often experience cognitive decline. Previous studies used normal volunteers, published normal test values, and orthopedic patients as controls to identify factors for postoperative cognitive decline. The present study excluded the effects of surgery by comparing cognitive function after surgical repair in patients with aneurysmal SAH and patients with unruptured intracranial aneurysm. ⋯ The cognitive function after SAH was significantly correlated with Hunt and Hess grade on admission when using patients with postoperative unruptured intracranial aneurysm as the control group.

Case Reports Randomized Controlled Trial
Clinical evaluation and follow-up outcome of presurgical plan by Dextroscope: a prospective controlled study in patients with skull base tumors.
Patient-specific approach design, comprehensive evaluation on perioperative data, and follow-up of postoperative life quality (KPS) were carried out to evaluate the application of VR technology of Dextroscope in procedures of patients with skull base tumors. ⋯ The preoperative plans with VR technology in patients with skull base tumor or CSF leakage operations can help certain the diagnosis, individually locate the position of skull base lesions, and design patient-specific approach, which also facilitate to shorten operation duration and the postoperative LOS, reduce total blood loss and injury of vessels in operation, and improve the postoperative KPS.

Although C1 lateral mass fixation technique is frequently performed in upper cervical instabilities, it requires the guidance of fluoroscopic imaging. The fluoroscopy guidance is time-consuming and has the risks of accumulative radiation. Biplane fluoroscopy is also difficult in upper cervical pathologic conditions because of the use of cranial fixations. This study aimed to demonstrate that unicortical C1 lateral mass screws could be placed safely and rapidly without fluoroscopy guidance. ⋯ C1 lateral mass screws may be used safely and rapidly in upper cervical instabilities without intraoperative fluoroscopy guidance and the use of the spinal navigation systems. Preoperative planning and determining the ideal screw insertion point, the ideal trajections, and the lengths of the screws are the most important points.

Despite a lot of research into patient selection, a significant number of patients fail to benefit from surgery for symptomatic lumbar disk herniation. We have used Fuzzy Logic-based fuzzy inference system (FIS) for identifying patients unlikely to improve after disk surgery and explored FIS as a tool for surgical outcome prediction. ⋯ Fuzzy inference system is a sensitive method of predicting patients who will fail to improve with surgical intervention.
