World Neurosurgery: Case Reports Surgical Management of Trigeminal Neuralgia in Children.
Trigeminal neuralgia (TN) is a well-recognized facial pain syndrome. Discrete forms with disparate pain symptoms include classic and atypical. However, atypical facial pain includes neuralgiform pain along a spectrum. Most cases of TN are diagnosed in the adult population. Case reports and series of children have presented TN as a similar entity, with treatment similar to that for adults. We reviewed the pertinent data and present 2 pediatric TN cases successfully treated with microvascular decompression (MVD). ⋯ Few studies have reported on the effectiveness of MVD in the pediatric population for the management of TN. The supporting data and our 2 cases have demonstrated that MVD is effective for pediatric patients to treat their TN. Furthermore, the side effects appear to be minimal, with excellent pain relief after MVD in this patient population.

Ewing's sarcoma family tumors (ESFTs) are the second most common malignancy in children and adolescents. The purpose of the present retrospective study was to evaluate the prognostic role of inflammatory biomarkers and preoperative D-dimer levels in patients with spinal ESFTs. ⋯ Our results have indicated that the preoperative D-dimer level is an effective prognostic factor with discriminatory ability for DFS and OS, superior to other indicators. Also, CAR was favorable prognostic factor for OS. Nomograms of DFS and OS can be recommended as practical models to evaluate the prognosis for patients with spinal ESFTs.

Hypoxia-inducible factor (HIF) plays a major role in tumorigenesis and cancer progression. In hypoxic conditions, HIF is upregulated and has been shown to activate multiple genes required for cells to adapt to hypoxia. AT-rich interactive domain-containing protein 1A (ARID1A), a SWI/SNF (switch/sucrose nonfermentable) chromatin remodeling gene has context-dependent tumor-suppressive and oncogenic roles in cancer. We assessed the correlations between the expression and mutations of HIF1A and ARID1A in histopathologically confirmed pituitary adenomas. ⋯ In our patient cohort, we found that most pituitary adenomas expressed HIF1A. To the best of our knowledge, we are the first to assess the presence of ARID1A loss in pituitary adenomas, which occurred in 28.2% of cases. No individual demographic, imaging, or histopathological feature was predictive of ARID1A. Likewise, with the exception of an increased incidence of cavernous sinus invasion, no correlation was found with HIF1A. Given the prognostic value of these markers in other malignancies, their frequency in pituitary adenomas warrants further exploration of their potential role in pituitary adenoma treatment and outcome.

With a rapidly expanding elderly population in the United States, the incidence of pituitary adenomas in elderly will continue to rise. In this study, we aim to evaluate the safety and efficacy of transsphenoidal endoscopic endonasal resection for pituitary adenomas in the elderly population. ⋯ The transsphenoidal endoscopic endonasal approach can be a safe and effective technique for resection of pituitary adenomas in patients >70 years old with appropriate patient selection.

Aneurysmal subarachnoid hemorrhage secondary to ruptured small dissecting fusiform aneurysms of the posterior inferior cerebellar artery (PICA) is rare and particularly challenging. Different treatment strategies have been reported in these rare cases. We report 2 patients treated with a novel endovascular approach. ⋯ There is no single treatment strategy suitable for all PICA aneurysms. Our proposed method may be best applied to small dissecting fusiform aneurysms located on a small (≤1 mm in diameter) PICA distally to its origin.
