Multiple biopsy samples are warranted for the histomolecular diagnosis of diffuse gliomas in the current molecular era, which possibly increases morbidity.

We assessed diagnostic yield, safety, and risk factors of postoperative morbidity after robot-assisted serial stereotactic biopsy sampling along 1 biopsy trajectory for diffuse gliomas.

Observational retrospective analysis of consecutive magnetic resonance imaging-based robot-assisted stereotactic biopsies performed at a single institution to assess the diagnosis of nonresectable newly diagnosed supratentorial diffuse gliomas in adults (2006-2016).

In 377 patients, 4.2 ± 1.9 biopsy samples were obtained at 2.6 ± 1.2 biopsy sites. The histopathologic diagnosis was obtained in 98.7% of cases. Preoperative neurologic deficit (P= 0.030), biopsy site hemorrhage ≥20 mm (P= 0.004), and increased mass effect on postoperative imaging (P= 0.014) were predictors of a new postoperative neurologic deficit (7.7%). Postoperative neurologic deficit (P < 0.001) assisted stereotactic biopsy sampling results in high diagnostic accuracy with low complication rates. Multiple biopsy sites and samples do not increase postoperative complications.

A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach.

A retrospective review of pediatric patients with lumbar disc disease who had undergone microdiscectomy at our institution from 2005 to 2016 was conducted. The preoperative presentation, hospital course, postoperative course, and follow-up data (≥3 years) were reviewed. We evaluated the risk factors for LDH and the surgical outcomes for both groups.

A total of 52 pediatric patients had undergone 61 lumbar disc surgeries for LDH in our department from 2005 to 2016. Their average age at surgery was 16.65 years. Of the 61 procedures, 48 (78.7%) had been performed via the minimally invasive spine microdiscectomy approach and 13 (21.3%) via the open microdiscectoques are demonstrably safe and useful in this patient population.

Limited information is available about the hospital types to which patients with intracerebral hemorrhage (ICH) are admitted and treated. This could be important because some effective therapeutic measures can only be administered at comprehensive stroke centers (CSCs).

Using the Acute Hospitals Discharge database, which provides population-based information, we identified ICH patients admitted to 7 CSCs and 53 non-CSCs (from January 2015 to December 2016) in Catalonia. CSCs were defined as centers with an emergency department ready to assess and treat code stroke patients around the clock, 24-hour availability of neurology, neurosurgery, and neuroradiology services, and admission to the stroke unit and/or intensive care unit. The database provided the demographics, admitting hospital, and interhospital transfers. Crizotinib Vital status was retrieved from the Central Registry of the Catalan Public Health Insurance.

A total of 3339 ICH patients were identified (mean age, 72.2 ± 14.6 years; 56.8% men). Of the 3339 ype and whether the routing protocols for ICH patients should be modified.

Patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) are considered to have a poor prognosis. However, the underlying reason for the association between the aneurysmal characteristics and poor-grade aSAH is still unclear. In the present study, we retrospectively evaluated the independent risk factors for patients with anterior communicating artery (ACoA) aneurysms with poor-grade aSAH.

From January 2009 to January 2016, 477 consecutive patients with ruptured ACoA aneurysms were included in the present study. Poor-grade aSAH was defined as a World Federation of Neurosurgical Society grade of IV or V, and good-grade aSAH was defined as a grade of I-III. Univariate and multivariable regression analyses were used to investigate the differences in aneurysm morphology and clinical characteristics between the 2 groups.

On univariate analysis, older patients (P= 0.038), larger aneurysm size (P= 0.013), larger size ratio (P= 0.007), larger aspect ratio (P= 0.009), positive history of stroke (P= 0.0 for patients with the potential for poor-grade aSAH.

Cushing disease (CD) is a rare clinical disease in which brain structural and function are impaired as the result of excessive cortisol. However, little is known whether rich-club organization changes in patients with CD, as visualized on resting-state magnetic resonance imaging (fMRI), can reverse to normal conditions after transsphenoidal surgery (TSS). In this study, we aimed to investigate whether the functional connectivity of rich-club organization is affected and whether any abnormal changes may reverse after TSS.

In this study, 38 patients with active CD, 33 with patients with CD in remission, and 41 age-, sex-, and education-matched healthy control participants underwent resting-state fMRI. Brain functional connectivity was constructed based on fMRI and rich club was calculated with graph theory approach. We constructed the functional brain networks for all participants and calculated rich-club connectivity based on fMRI.

We identified left precuneus, right precuneus, left middle cingulum, righ excessive cortisol on brain functional connectivity in patients with CD.

To investigate the clinical characteristics and factors affecting the prognosis of myxopapillary ependymoma (MPE).

We retrospectively analyzed the clinical data of 24 patients diagnosed with MPE who were surgically treated from January 2010 to January 2020 in the Department of Neurosurgery at Tongji Hospital (Tongji Medical School, Huazhong University of Science and Technology).

Among the 24 included patients, there were 13 male and 11 female patients. The ages of the included patients ranged from 15 to 59 years old, with an average age of 35.2 years old. The Preoperative McCormick grade included 20 cases (83.3%) that were grade II and 4 cases (16.7%) that were grade III. The follow-up times ranged from 6 months to 10 years, with an average of 50.9 months. The Postoperative McCormick grade included 7 cases (29.2%) that were grade I, 4 cases (16.7%) that were grade II, 12 cases (50%) that were grade III and 1 case (4.2%) that was grade IV. The 1-year, 2-year, and 10-year recurrence rate was 8.3%, 29.2%, 41.
