Spinal epidural arteriovenous fistulas (SEAVFs) are the rarest variety of spinal vascular malformation and are often misdiagnosed as type 1 spinal dural fistula. This retrospective study highlights the salient anatomic differentiating points of these entities and also highlights the importance of a planned endovascular treatment approach using different routes of access. Efficacy of the endovascular treatment at 3 months follow-up was also studied. ⋯ The differentiating points between SEAVF compared with type 1 spinal dural fistula are emphasized. The study also highlights the importance of a good angiographic assessment to best access the fistula by arterial, venous, percutaneous, or combined routes. Endovascular treatment resulted in statistically significant clinical improvement at 3 months follow-up.

Meningioma has the second highest incidence among primary intracranial tumors. There is no effective treatment or targeted therapy for meningioma except excision and radiotherapy. Sp1 (specificity protein 1) is a transcription factor that regulates tumor growth, but the literature describing the relationship between Sp1 and meningioma is scarce. The purpose of this study was to investigate the relationship between Sp1 expression and the clinicopathological parameters in meningioma by immunohistochemical staining. ⋯ High expression of Sp1 in patients with meningioma was linked to poor prognosis of recurrence-free time. Therefore Sp1 may be a candidate biomarker of prognosis and therapy target in meningioma.

This work aimed to analyze the value of serum platelet/lymphocyte ratio (PLR), carbohydrate antigen 125 (CA125), and diffusion-weighted imaging (DWI) in the diagnosis of recurrent ovarian cancer. ⋯ CA125 and PLR combined with DWI had the best diagnostic effect for patients with recurrent ovarian cancer. After treatment, the levels of PLR and CA125 were reduced and the quality of life of patients was improved.

In recent years, there has been increasing study of ossification of the posterior longitudinal ligament (OPLL), leading to many articles on this topic. We aimed to identify trends in OPLL-related research and to analyze the most highly cited scientific articles on OPLL. ⋯ The scientific literature on OPLL has rapidly expanded in recent years. This study represents the first bibliometric analysis of scientific articles on OPLL and can serve as a useful guide to clinicians and researchers in the field.

Although various predictors of adverse postoperative outcomes among patients with meningioma have been established, research has yet to develop a method for consolidating these findings to allow for predictions of adverse health care outcomes for patients diagnosed with skull base meningiomas. The objective of the present study was to develop 3 predictive algorithms that can be used to estimate an individual patient's probability of extended length of stay (LOS) in hospital, experiencing a nonroutine discharge disposition, or incurring high hospital charges after surgical resection of a skull base meningioma. ⋯ After external validation, our predictive models have the potential to aid clinicians in providing patients with individualized risk estimation for health care outcomes after meningioma surgery.
