Background: Idiopathic intracranial hypertension (IIH) is an increasingly prevalent disease bearing the risk of visual impairment and affecting quality of life. Clinical presentation and outcome are heterogeneous. Large, well-characterized cohorts are scarce.Here, we describe the Vienna-Idiopathic-Intracranial-Hypertension (VIIH) database aiming to characterize the clinical spectrum, diagnostic findings, therapeutic management, and outcome of IIH.Methods: We identified patients with IIH according to the modified Dandy criteria who were treated at our center between 2014 and 2021. Methodology and structure of the VIIH database are described in detail including demographics, clinical parameters, magnetic resonance imaging, optical coherence tomography, transorbital sonography, treatment, and outcome.Results: Of 113 patients, 89% were female (mean age 32.3 years). Median body mass index (BMI) was 31.8, with 85% overweight (BMI>25). Papilledema was found in 95% with 5% classified as IIH without papilledema. Headache was present in 84% and showed migrainous features in 43%. Median opening pressure in lumbar puncture was 31cmH2O.Pharmacotherapy (predominantly acetazolamide) was established in 99%, 56% required at least one therapeutic lumbar puncture and 13% surgical intervention. After a median follow-up of 3.7 years, 43% had not achieved significant weight loss, papilledema was present in 59% and headache in 76% (58% improved). Comparing initial presentation to follow-up, perimetry was abnormal in 67% vs. 50% (8% worsened, 24% improved) and transorbital sonography in 87% vs. 65% with a median optic nerve sheath diameter of 5.4mm vs. 4.9mm. Median peripapillary retinal nerve fiber layer thickness had decreased from 199µm to 99µm and ganglion cell layer volume from 1.13mm3 to 1.05mm3.Conclusions: The VIIH database constitutes a large representative cohort, characterizing IIH-related symptoms, diagnostic findings, treatment, and outcome parameters and emphasizing substantial long-term sequelae of IIH. Future analyses will aim to refine phenotyping and identify factors predicting outcome.

Objective To assess the prognostic impact of migraine headache in idiopathic intracranial hypertension (IIH). Background Migraine headache is common in IIH, but it is unclear whether it has prognostic relevance. Methods We investigated patients with IIH from the Vienna‐IIH‐database and differentiated migraine (IIH‐MIG) from non‐migraine headache (IIH‐nonMIG) and without headache (IIH‐noHA). Using multivariable models, we analyzed the impact of IIH‐MIG on headache and visual outcomes 12 months after diagnosis. Results Among 97 patients (89% female, mean [SD] age 32.9 [11.1] years, median body mass index 32.0 kg/m2, median cerebrospinal fluid opening pressure 310 mm), 46% were assigned to IIH‐MIG, 37% to IIH‐nonMIG (11% tension‐type, 26% unclassifiable), and 17% to IIH‐noHA. Overall, headache improvement was achieved in 77% and freedom of headache in 28%. The IIH‐MIG group showed significantly lower rates for headache improvement (67% vs. 89% in IIH‐nonMIG, p = 0.019) and freedom of headache (11% vs. 33% in IIH‐nonMIG and 63% in IIH‐noHA, p = 0.015). These differences persisted when only analyzing patients with resolved papilledema at follow‐up. In contrast, visual worsening was significantly less common in IIH‐MIG (9% vs. 28% in IIH‐nonMIG and 31% in IIH‐noHA, p = 0.045). In multivariable models, IIH‐MIG was associated with a significantly lower likelihood of achieving headache improvement (odds ratio [OR] 0.57, 95% confidence interval [CI] 0.40–0.78, p < 0.001) and freedom of headache (OR 0.29, 95% CI 0.12–0.46, p < 0.001), but also a lower risk for visual worsening (OR 0.26, 95% CI 0.04–0.82, p < 0.001). Conclusions In IIH, migraine headache is associated with unfavorable outcomes for headache, even when papilledema has resolved, and possibly favorable visual outcome.

BackgroundPenetrating brain injury (PBI) is a heterogeneous condition with many variables. Few data exist on civilian PBI. In some publications, PBI differentiation between low-velocity injury (LVI) and high-velocity injury (HVI) is made, but exact definitions are not given yet. The incidence of PBI depends heavily on the country of origin. Furthermore, captive bolt pistol (CBP) injuries represent a rare type of LVI and almost no reports exist in the human medical literature. Treatment of PBI has been controversially discussed due to high morbidity and mortality with results varying considerably between series. Prognostic factors are of utmost importance to identify patients who presumably benefit from treatment.MethodsA retrospective, single-center analysis of a consecutive patient series was performed from September 2005 to May 2018. We included all patients with PBI who reached our hospital alive and received any neurosurgical operative procedure.ResultsOf 24 patients, 38% died, 17% had an unfavourable outcome, and 46% had a favourable outcome. In total, 58% of patients with PBI were self-inflicted. Leading causes of injury were firearms, while captive bolt pistols were responsible for 21% of injuries. LVI represented 54%, and HVI represented 46%. The outcome in HVI was significantly worse than that in LVI. A favourable outcome was achieved in 69% of LVI and 18% of HVI. Low GCS and pathological pupillary status at admission correlated significantly with an unfavourable outcome and death.ConclusionsPBI is a heterogeneous injury with many variables and major geographical and etiological differences. Differentiation between LVI and HVI is crucial for decision-making and predicting outcomes. In patients presenting with object trajectories crossing the midline, no favourable outcome could be achieved. Nevertheless, in total, a favourable outcome was possible in almost half of the patients who succeeded in surgery.

Purpose To investigate the clinical value of the inflammation based prognostic scores for patients with radiosurgically treated brain metastases (BM) originating from non-pulmonary primary tumor (PT). Methods A retrospective analysis of 340 BM patients of different PT origin (melanoma, breast, gastrointestinal, or genitourinary cancer) was performed. Pre-radiosurgical laboratory prognostic scores, such as the Neutrophil-to-Lymphocyte Ratio (NLR), the Platelet-to-Lymphocyte Ratio (PLR), Lymphocyte-to-Monocyte Ratio (LMR), and the modified Glasgow Prognostic Score (mGPS), were investigated within 14 days before the first Gamma Knife radiosurgical treatment (GKRS1). Results In our study cohort, the estimated survival was significantly longer in patients with NLR < 5 (p < 0.001), LMR > 4 (p = 0.001) and in patients with a mGPS score of 0 (p < 0.001). Furthermore, univariate and multivariate Cox regression models revealed NLR ≥ 5, LMR < 4 and mGPS score ≥ 1 as independent prognostic factors for an increased risk of death even after adjusting for age, sex, KPS, extracranial metastases status, presence of neurological symptoms and treatment with immunotherapy (IT) or targeted therapy (TT). Conclusions Summarizing previously published and present data, pre-radiosurgical mGPS and NLR groups seem to be the most effective and simple independent prognostic factors to predict clinical outcome in radiosurgically treated BM patients.
