    Abstract Background: Decision about treatment of incidentally found intracranial meningiomas is controversial and conditioned by the growth potential of these tumors. We aimed to evaluate the growth rate of a cohort of incidentally found asymptomatic meningiomas and to analyze their natural course and the need for eventual treatment.
    Methods: A total of 193 patients harboring intracranial meningiomas (85 with 109 incidental and 108 with 112 symptomatic) were included between 2015 and 2019. In the prospective cohort of incidental meningiomas, we measured size at diagnosis, volumetric growth rate (by segmentation software), appearance of symptoms, and need for surgery or radiotherapy. Progression-free survival and risk factors for growth were assessed with Kaplan-Meier survival and Cox regression analyses.
    Results: Among incidental meningiomas, 94/109 (86.2%) remained untreated during a median follow-up of 49.3 months. Tumor growth was observed in 91 (83.5%) and > 15% growth in 40 (36.7%). Neurological symptoms developed in 1 patient (1.2%). Volume increased an average of 0.51 cm
    Conclusions: Overall, 86% of incidentally found meningiomas remained untreated over the first 4 years of follow-up. The majority grew within the 20% range, yet very few developed symptoms. Treatment-related morbidity was absent in the incidental meningioma group.

    Abstract Objective: To assess the effectiveness and safety of vancomycin powder as surgical site infection (SSI) prophylaxis in posterior bilateral elective spinal surgery.
    Materials and methods: Single-center quasi-experimental pre and postintervention comparative cohort study. The post-intervention group received standard intravenous antibiotic prophylaxis plus 1g of vancomycin powder into the surgical field before wound closure, and the pre-intervention group only the intravenous prophylaxis.
    Results: 150 patients were included in each group. Twelve SSI (7 superficial and 5 deep) occurred in the post-intervention group and 16 SSI (7 superficial and 9 deep) in the pre-intervention group. The risk of deep SSI decreased from 6.0% to 3.3% (OR 0,54, 95%CI 0.17-1.65, p=0.411) with vancomycin powder. The percentage of deep SSI due to gram negative-positive germs were 80%-20% and 33%-67% for the post- and pre-intervention groups, respectively (p=0.265). No local or systemic adverse effects occurred attributable to vancomycin powder.
    Conclusion: In posterior elective spinal surgery, prophylaxis with vancomycin powder did not result in a significantly reduced incidence of superficial and deep SSI. There was a trend towards a higher incidence of deep SSI caused by gram negative microorganisms among those treated with vancomycin.

    Abstract Objective: Cauda equina syndrome (CES) caused by lumbar disk extrusion is classically considered an indication of urgent surgery. CES can be subdivided into CESI (incomplete CES) and CESR (complete CES with urinary retention and incontinence). This paper evaluates the long-term functional outcome of a CES cohort operated on due to disk herniation.
    Methods: Single-center retrospective observational study. CES patients due to disk herniation that underwent surgery between 2000 and 2016 were included in the study. Demographic data, time intervals to diagnosis and surgery, preoperative neurologic status and outcome at the end of follow up were recorded.
    Results: Twenty-two patients were included (median age 44 years). Eight patients were CESR and 14 CESI. Median time from symptom onset to diagnosis was 78h (range, 12-720h), and from diagnosis to surgery 24h (range, 5-120h). Median follow up was 75 months (range, 20-195 months). At the end of follow up, in the CESR group (median time from diagnosis to surgery, 23h) only pain significantly improved after surgery (p=0.007). In the CESI group (median time from diagnosis to surgery 23h) low back pain, sciatica and urinary sphincter function significantly improved (p<0.001). There were no significant differences between early (<48h) operation (n=4) and late (n=18) in terms of sphincter recovery (Fisher's Exact Test, p=0.076).
    Conclusion: Pain associated to CES improved both in the CESI and CESR groups. However, urinary sphincter impairment significantly improved only in the CESI group. No significant differences were found regarding long-term functional outcome between early and late surgery.

    Abstract Purpose: Clinical diagnosis of human prion diseases can be challenging since symptoms are common to other disorders associated with rapidly progressive dementia. In this context, (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) might be a useful complementary tool. The aim of this study was to determine the metabolic pattern in human prion diseases, particularly sporadic Creutzfeldt-Jakob disease (sCJD), the new variant of Creutzfeldt-Jakob disease (vCJD) and fatal familial insomnia (FFI).
    Methods: We retrospectively studied 17 patients with a definitive, probable or possible prion disease who underwent FDG PET in our institution. Of these patients, 12 were diagnosed as sCJD (9 definitive, 2 probable and 1 possible), 1 was diagnosed as definitive vCJD and 4 were diagnosed as definitive FFI. The hypometabolic pattern of each individual and comparisons across the groups of subjects (control subjects, sCJD and FFI) were evaluated using a voxel-based analysis.
    Results: The sCJD group exhibited a pattern of hypometabolism that affected both subcortical (bilateral caudate, thalamus) and cortical (frontal cortex) structures, while the FFI group only presented a slight hypometabolism in the thalamus. Individual analysis demonstrated a considerable variability of metabolic patterns among patients, with the thalamus and basal ganglia the most frequently affected areas, combined in some cases with frontal and temporal hypometabolism.
    Conclusion: Patients with a prion disease exhibit a characteristic pattern of brain metabolism presentation in FDG PET imaging. Consequently, in patients with rapidly progressive cognitive impairment, the detection of these patterns in the FDG PET study could orient the diagnosis to a prion disease.

    Abstract Background: Several reports found a relationship between increased serum lead levels and the risk for essential tremor (ET), especially in carriers of the minor allele of the single nucleotide polymorphism (SNP) rs1800435 in the aminolevulinate dehydratase (ALAD) gene, which is involved in the synthesis of haem groups. Our group reported decreased risk for ET in carriers of the minor alleles of the rs2071746 and rs1051308 SNPs in the haem-oxygenases 1 and 2 (HMOX1 and HMOX2), respectively, involved in haem metabolism. We analysed whether ALAD rs1800435 alone and their interactions with the four common SNPs in the HMOX1 and HMOX2 genes are associated with the risk for ET.
    Materials and methods: We analysed the genotype and allele variants frequencies of ALAD rs1800435 in 202 patients with familial ET and 218 healthy controls using a TaqMan method. We also analysed the role of the interaction between ALAD rs1800435 and the HMOX1 rs2071746, HMOX1 rs2071747, HMOX2 rs2270363 and HMOX2 rs1051308 with the risk of developing ET.
    Results: The frequencies of genotype and allelic variants of ALAD rs1800435 did not differ significantly between patients with ET and controls, and were not influenced by gender. Subjects carrying the ALAD rs1800435CC genotype (wild-type) and the HMOX2 rs1051308GG genotype or the HMOX2 rs1051308G allele had significantly decreased risk for ET.
    Conclusions: These results suggest that the ALAD rs1800435 SNP is not related with the risk for ET, but its interaction with the HMOX2 rs1051308 SNP could be weakly associated with the risk for this disease.

    Title translation Role of surgery in spontaneous spondylodiscitis: Experience in 83 consecutive patients.
    Abstract Objective: To describe and discuss the role of surgery in the management of spontaneous spondylodiscitis.
    Patients and methods: Retrospective review on the outcome and complications of a cohort of patients undergoing surgery for spontaneous (non-postoperative) spondylodiscitis of any spinal level or aetiology.
    Results: From 1995 to 2014, 83 patients (45% females, median age 66) with spondylodiscitis were treated. Microbiological confirmation was obtained in 67.4%. Forty-four percent of patients presented with neurological defect. The most common affected level was thoracic (54.2%). The most frequent isolations were Mycobacterium tuberculosis (229%), Staphylococcus aureus (20.5%) and MRSA (7.2%). Eighty-one patients underwent surgery: simple laminectomy and/or biopsy (22.2%), debridement and posterior fixation (43.2%) and debridement and anterior fixation (34.5%). Improvement of pain or neurological defect was achieved in 86.7% of the patients; 7 patients stabilized and 2 worsened. Complications occurred in 35 patients, mainly pleural effusion (9), anaemia (7) and need for re-debridement (7). Median postoperative stay was 14days. After a median follow up of 8.5 months, 46 patients were considered completely cured, 10 presented sequelae, 22 patients were lost and 5 patients died. No readmissions occurred because of the infectious episode.
    Conclusions: Although prolonged and specific antibiotic therapy remains the mainstay of treatment in spontaneous spondylodiscitis, surgery provides samples for microbiological confirmation and histopathologic study, allows debridement of the infectious foci and stabilizes the spine. In our experience, the use of internal metallic fixation material accelerates recovery and does not predispose to chronic infection.

    Abstract Eighteen loci and several susceptibility genes have been related to Parkinson's disease (PD). However, most studies focus on single genes in small PD series. Our aim was to establish the genetic background of a large Spanish PD sample. Pooled-DNA target sequencing of 7 major PD genes (SNCA, PARK2, PINK1, DJ-1, LRRK2, GBA, and MAPT) was performed in 562 PD cases. Forty-four variants were found among 114 individuals (20.28%, p<0.05). Among these variants, 30 were found in Mendelian genes (68.18%) and 14 in PD susceptibility genes (31.82%). Seven novel variants were identified. Interestingly, most variants were found in PARK2 and PINK1 genes, whereas SNCA and DJ-1 variants were rare. Validated variants were also genotyped in Spanish healthy controls (n = 597). Carriers of heterozygous PARK2 variants presented earlier disease onset and showed dementia more frequently. PD subjects carrying 2 variants at different genes (1.42%) had an earlier age of onset and a predominantly akinetic-rigid PD phenotype (55.6%, p < 0.05), suggesting that the accumulation of genetic risk variants could modify PD phenotype.
