After exposure, the musculoosseous unit was easily repositioned, thus allowing for C1-C2 laminoplasty. Grossly, no damage to the vertebral artery or regional nerves was noted.

We present a novel, unilateral minimally invasive approach to reach the atlantoaxial and craniovertebral junction. This could allow for faster postoperative recovery, less pain and opioid requirement, and increased maintenance of atlantoaxial stability. Such a technique, after being confirmed in patients, could optimize this surgical technique.

Deep brain stimulation (DBS) is an important treatment for patients with advanced Parkinson’s disease (PD). Patients after DBS implantation need specialized programming to get optimal outcomes. However, access to timely and economical postoperative programming for many patients living in remote areas is limited. Teleprogramming, which refers to deliver real-time remote programming through Internet, can help to address this gap.

We aimed to evaluate the clinical application of remote programming for PD patients with DBS.

We retrospectively studied 90 patients with PD who received remote DBS programming after implantation at Yuquan Hospital (Beijing, China) between March 2016 and June 2018. Patients’ medical records were reviewed in an electronic database. A self-designed questionnaire was performed on all patients by phone.

Over a mean follow-up period of 27.0 months, 90 patients underwent a total of 386 remote programming visits, of which the average frequency within 6 months after DBS was 2.27 times/person. The average distance between the patients’ residences and Yuquan Hospital was 1243.8 ± 746.5 km. The questionnaire survey showed that each remote programming visit saved ≥2000¥ for 76.7% of the patients and ≥12 hours for 90.0% of the patients, compared with the on-site programming visit. The acceptability of the remote programming platform was highly rated. Transient side effects related to programming were reported and were relieved after adjustments of parameters.

Remote programming may offer a feasible and acceptable approach to timely and economic management in patients with PD after DBS implantation.

Newly emerged molecular markers in gliomas provide prognostic values beyond the capabilities of histologic classification. BRAF mutation, especially BRAF V600E, is common in a subset of gliomas and may represent a potential prognostic marker. The aim of our study is to investigate the potential use of BRAF mutations on the prognosis of low-grade glioma patients.

Four electronic databases were searched for potential articles including PubMed, Web of Science, Embase, and Cochrane. Data of hazard ratio (HR) for overall survival and progression-free survival were directly obtained from original papers or indirectly estimated from the Kaplan-Meier curve. A random effect model weighted by inverse variance method was used to calculate the pooled HR. From 483 articles, we finally included 8 articles with 698 glioma patients for the final analysis. The overall estimates showed that BRAF V600E was associated with an improved overall survival in glioma patients (HR= 0.64; 95% confidence interval= 0.45-0.92).

Results for progression-free survival, however, were not statistically significant (HR= 0.97; 95% confidence interval= 0.7-1.36). In subgroup analyses, BRAF V600E showed its effect in improving survival in pediatric patients but did not have prognostic value in adult. Our meta-analysis provides evidence that BRAF mutation has a favorable prognostic impact in low-grade gliomas, and its prognostic value might be dependent on patient age.

This mutation can be used as a prognostic factor in low-grade glioma, but additional studies are required to clarify its prognostic value taking into account other confounding factors.

Lateral ventricular meningioma (LVM) is a rare entity, accounting for 0.5%-5% of all intracranial meningiomas. This type of meningioma arises from meningothelial inclusion bodies in the tela choroidea and/or mesenchymal stroma of the choroid plexus. Although not yet fully characterized, a membranous structure is frequently observed around LVMs. This study analyzed quiescent and activated fibroblast phenotypes in LVMs with focus on the relationship between tumor growth and development of the membranous structure.

This retrospective study analyzed 9 LVM cases for which gross total removal was achieved. Expression of the ependymal cell marker (Forkhead Box J1 [FoxJ1]) was histopathologically evaluated. The distribution of quiescent and activated fibroblasts was also analyzed using anti-fibroblast-specific protein-1 (FSP1)/S100A4 antibody and anti-α-smooth muscle actin (αSMA) antibody, respectively. The control group was 5 cases with primary convexity meningioma for which Simpson grade I removal was achieved.

Small LVMs (≤30 mm) were covered by a FoxJ1-positive(+) ependymal cell monolayer; no αSMA(+) cells were detected in the tumor; and a thick membrane capsule was not observed. None of the convexity meningiomas showed FoxJ1(+) cells. Large LVMs (>30 mm) had thick membrane capsules without an ependymal cell monolayer, which resembled dura mater. The FSP1/S100A4(+) and αSM(+) cells were clearly concentrated in the peripheral area just below the thick dura mater-like membrane capsules.

This study found an association between activated fibroblasts and dura mater-like membrane capsules in LVMs. The characteristics of membranous structure in LVMs may differ depending on tumor size.
