    Abstract Background/aim: Malignant peripheral nerve sheath tumors (MPNST) are rare soft tissue malignant tumors. To the best of our knowledge, there have been no previous reports of benign reactive histiocytosis with hematoma that mimics MPNST on medical images.
    Case report: A 57-year-old female with past history of hypertension came to our clinic due to low back pain with radiculopathy which was diagnosed with a tumor arising from L2 neuroforamen with L2 pedical erosion. Initial tentative diagnosis on the images was MPNST. However, after surgical resection, the pathologic report revealed no evidence of malignancy but only an organized hematoma with reactive histiocytosis.
    Conclusion: Images cannot provide enough diagnostic evidence for distinguishing a reactive histiocytosis from MPNST. Proper surgical procedures and expert pathological identification can correct the mistaking of the ambiguous identification as MPNST. Images can only provide precise and personalized medication accompanied by proper surgical procedures and expert pathological identification.

    Abstract Intradural disc herniation (IDH) is an extremely rare condition. The authors report the case of a 53-year-old female who had neck and right shoulder pain associated with right-sided hemiparesis and hyperesthesia. Magnetic resonance imaging (MRI) of the cervical spine (C-spine) revealed central mass-like lesions that caused the; compression of the right side of the spinal cord. The posterior surgical approach was used to remove two pieces of IDH. After surgery, the muscle strength in the right upper limb improved from Grade 0/5 to 4+/5 without surgery-related complications. Although there are some reports in literature on the radiologic features of cervical IDH (including the Halo sign, Y-sign, hawk-beak sign, and crumble disc sign), it can be difficult to diagnose radiologically. We present the clinical image of the case along with a review of the literature to remind surgeons to consider IDH as a differential diagnosis when patients are affected by anterior intradural lesions.

    Abstract Background/aim: Canonical burr-hole craniostomy (BHC) with drainage is the primary treatment for chronic subdural hematomas. However, complicated situations such as organized clots or compartmentation may result in recurrent chronic subdural hematoma (CSDH). Herein, we introduce a novel technique by applying an endoscope for tearing the inner membrane and septum, in addition to evacuating the hematoma in the subdural space where in-line visualization is not possible.
    Patients and methods: Two hundred and twenty-nine cases of CSDH were enrolled in this study. Of these, 13 patients were treated endoscopically. The 0-degree and 30-degree, 2.7 mm endoscope was applied after a BHC. The arachnoid knife for microsurgery was used to tear the inner membrane to open the compartments.
    Results: Non-endoscope-assisted operated (non-Endo group) and endoscope-assisted membranectomy patients (Endo group) demonstrated no differences in sex, age, body mass index, trauma, other diseases, or use of anticoagulation agents. Although the surgery time spent for the Endo patients was longer (128.53±49.56 min) than that for the non-Endo group (65.18±32.89 min), no recurrence was found among the Endo group, whereas a higher rate was observed in the non-Endo group.
    Conclusion: Novel endoscope-assisted membranectomy is a powerful technique capable of reducing recurrence and improving surgical outcomes.

    Abstract This study aimed to compare the differences in radiological outcomes and complications between single- and multilevel anterior cervical discectomy and fusion (ACDF) by using a polyetheretherketone (PEEK) cage-plate fusion system.Fifty-seven patients who underwent ACDF via the PEEK cage-plate fusion system were enrolled and subjected to ≥6 months of follow-up. The patients were divided into 4 groups according to different cage-plate implantation levels: 1-level group (n = 17), 2-level group (n = 24), 3-level group (n = 12), and 4-level group (n = 4). Fusion time, changes in segment and global lordotic angle, subsidence rate, and changes in disc and adjacent segmental disc height were subjected to radiological evaluation.The fusion period of multilevel ACDF was longer than that of single-level ACDF. The fusion period of the 3-level (4.09 ± 0.94, P = .004) and 4-level (5.25 ± 0.89, P = .004) group was also significantly longer than that of the 1-level group. The mean lordotic angle in all of the groups was changed in the immediate postoperative period and in the final follow-up. The cage subsidence rates were 11.76% (2/17) in the 1-level group, 20.83% (5/24) in the 2-level group, and 2/12 (16.67%) in the 3-level group. No subsidence occurred in the 4-level groups. Changes in the lower adjacent segmental disc height were significantly increased in multilevel ACDF compared with those in single-level ACDF.Despite the longer fusion time, the outcomes of the proposed system were even better with the greater number of treatment levels by using PEEK cage-plate fusion system. Changes in the lower adjacent segmental disc height should also prolong follow-up duration to investigate the symptomatic adjacent segment degeneration in multilevel ACDF.

    Abstract Primitive neuroectodermal tumors (PNETs) are easily detected, and the diagnosis made by neuroradiologic imaging. Leptomeningeal seeding is a common complication and carries a poor prognosis. Primary leptomeningeal PNETs are rarer and difficult to diagnose on magnetic resonance imaging (MRI) or cerebrospinal fluid (CSF) studies. We encountered a rare case of primary leptomeningeal primitive neuroectodermal tumor without intracranial mass lesion which was diagnosed by spinal lesion biopsy. This 25-year-old woman presented with worsening headaches and progressive visual impairment.The initial diagnosis was tubercle bacillus (TB) meningitis, and the final diagnosis of primary leptomeningeal PNET was made by spinal biopsy. We present this illustrative case, review previous cases in the literature, and suggest that diagnosis is considered in mildly affected patients with similar symptoms.

    Abstract 6-hydroxydopamine (6-OHDA) is used to induce oxidative damage in neuronal cells, which can serve as an experimental model of Parkinson's disease (PD). Jujuboside A and B confer free radical scavenging effects but have never been examined for their neuroprotective effects, especially in PD; therefore, in this study, we aimed to investigate the feasibility of jujubosides as protectors of neurons against 6-OHDA and the underlying mechanisms. 6-OHDA-induced neurotoxicity in the human neuronal cell lines SH-SY5Y and SK-N-SH, was used to evaluate the protective effects of jujubosides. These findings indicated that jujuboside A and B were both capable of rescuing the 6-OHDA-induced loss of cell viability, activation of apoptosis, elevation of reactive oxygen species, and downregulation of the expression levels of superoxide dismutase, catalase, and glutathione peroxidase. In addition, jujuboside A and B can reverse a 6-OHDA-elevated Bax/Bcl-2 ratio, downregulate phosphorylated PI3K and AKT, and activate caspase-3, -7, and -9. These findings showed that jujubosides were capable of protecting both SH-SY5Y and SK-N-SH neuronal cells from 6-OHDA-induced toxicity via the rebalancing of the redox system, together with the resetting of the PI3K/AKT apoptotic signaling cascade. In conclusion, jujuboside may be a potential drug for PD prevention.

    Abstract Background/aim: 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) is responsible for folate metabolism, and we aimed to investigate its genetic role in colorectal cancer (CRC) among Taiwanese.
    Materials and methods: A total of 362 cases and 362 controls were recruited and their MTRR rs1801394 (A66G) and rs1532268 (C524T) genotypes were examined. The behavioral factors and clinicalpathological factors were also analyzed.
    Results: MTRR rs1801394 genotypes were associated with CRC risk (p for trend=0.0087). In detail, G/G genotype was associated with lower risk (p=0.0049, OR=0.39, 95%CI=0.20-0.76). As for allelic frequency analysis, G allele was also associated with decreased CRC risk (p=0.0026, OR=0.68, 95%CI=0.53-0.88). There was no significant association as for MTRR rs1532268. Among non-smokers and non-alcohol drinkers, those with G/G genotype were at 0.38- and 0.46-fold odds of having CRC. There were no significant protective effects among smokers or alcohol drinkers.
    Conclusion: MTRR rs1801394 GG genotype can be a protective marker for CRC risk in Taiwan.

    Abstract This study aimed to verify the relationship between the number of fusion level and the risk of screw loosening by using cortical bone trajectory (CBT) screws in patients with lumbar degenerative disease.We retrospectively reviewed the serial plain radiograph images of lumbar degenerative disease patients who had undergone posterior fixation and fusion surgery with CBT from 2014. All included patients should have been followed-up with computed tomography scan or plain radiograph for at least 6 months after operation. We individually evaluated the prevalence of screw loosening according to each vertebral level. We also determined whether the number of screw fixation affected the prevalence of screw loosening and whether S1 fixation increased the risk of screw loosening.The screw-loosening rates were high at the S1 level. Moreover, although fixation involved to S1, the loosening rates evidently increased (Fisher exact test, P = .002). The screw-loosening rate was 6.56% in 2 level fusion. However, it increased with the number of fusion levels (3 level: 25.00%, 4 level: 51.16%, and 5 level: 62.50%). To investigate if the number of fusion level affected the S1 screw loosening, we classified the cohort of patients into either involving S1 (S1+ group) or not (S1- group) according to different fusion levels (). The screw loosening between 2 group in 2 (5.56% vs 6.98%) and 3 fusion level (26.32% vs 22.73%) did not exhibit any significant difference. Interestingly, significantly high screw loosening was found in 4 fusion level (60.00% vs 15.38%), indicating that the higher fusion level (4 level) can directly increase the risk of S1 screw loosening.Our data confirmed that the screw-loosening rate increases rate when long segment CBT fixation involves to S1. Therefore, in case of long-segment fixation by using CBT screw, surgeons should be aware of the fusion level of S1.
