Microelectrode recording (MER) and intraoperative magnetic resonance imaging (iMRI) have been used in deep brain stimulation surgery for Parkinson disease (PD), but comparative methodology is lacking. Therefore, we compared the 1-year follow-up outcomes of MER-guided and iMRI-guided subthalamic nucleus (STN) deep brain stimulation (DBS) surgery in PD patients. ⋯ MER and iMRI both are effective ways to ensure adequate electrode placement in DBS surgery, but there is no superiority between both techniques, at least in terms of 1-year follow-up outcomes.

Observational Study
Head Computed Tomography-Scan in isolated Traumatic Brain Injury in a Low Income Country.
Head computed tomography scan (HCTS) is the cornerstone of the management of traumatic brain injury (TBI). The impact of performing a HCTS in TBI has been scarcely investigated in low-income countries (LICs). Furthermore, the cost of a HCTS is a burden for family finances. ⋯ No modification of guidelines can be advocated from this study. However, given the financial burden on family of performing HCTS, research may identify criteria allowing for avoiding HCTS. Guidelines specific to LICs are needed to get closer to the best interest of patients.

To analyze 3T magnetic resonance imaging (MRI) findings and clinical features of patients with trigeminal neuralgia (TN) who underwent percutaneous balloon compression and to determine whether these findings had an impact on prognosis of TN. ⋯ Symptom duration was longer and microstructural changes were more apparent in patients with recurrence. In addition to age, comorbidities, and other clinical and radiographic features, symptom duration and FA values obtained with 3T MRI might be valuable information in surgical decision making.

To investigate the role of lumbosacral transitional vertebra (LSTV) in the pathogenesis of adolescent lumbar disc herniation (ALDH) and the association between LSTV type and the herniation level of ALDH. ⋯ The LSTV is associated with LDH in adolescents and the sacralization of L5 may contribute to the L4/5 disc herniation in adolescent patients.

Gross total resection is often avoided in posterior fossa ependymoma surgery because of the fear of permanent neurologic deficits after operation. However, the extent of resection is a major prognostic factor for progression-free and overall survival. This study evaluates the outcome of posterior fossa ependymoma gross total resection in adult patients using a 4-hand suction-irrigation technique at the floor of the fourth ventricle. ⋯ Long-term progression-free survival in adult patients suffering from posterior fossa ependymoma is possible by gross total resection without adjuvant radio- or chemotherapy. By careful bimanual microsurgical dissection using the 4-hand suction-irrigation technique and avoidance of bipolar coagulation on the floor of the fourth ventricle, the risk for permanent neurologic deficits is low.
