    Abstract Low back pain (LBP) is a common affliction with numerous causes. Some individuals experience LBP attributed to disc pathology. Disc pathology has been implicated in a plurality of cases of LBP, and some cases are associated with annular fissures (AFs). AFs are weaknesses in the structure that contains the nucleus pulposus and is the site of possible disc herniations. On magnetic resonance imaging (MRI), some AFs manifest as the high-intensity zone (HIZ), otherwise known as an annular enhancement region. In this report, we present three patients with LBP, mild radiculitis, and HIZ who later developed herniated nucleus pulposus (HNP) with extrusion through the HIZ. These cases suggest that HIZ indicates a propensity for the future development of disc extrusion through the weakened tissue at the AF visualized as HIZ on MRI. With a better understanding of the association between AFs and disc herniations with HIZ, clinicians may be able to predict and prevent the pain and disability associated with disc extrusion.

    Abstract In this study, a composite of zinc tungsten oxide nanoparticles (W-ZnO NPs) has been synthesized via mixing Na2WO4 and zinc acetate in water, followed by dropwise addition of NaOH. The synthesized W-ZnO NPs were characterized using measurement methods such as XRD, dynamic light scattering (DLS), Scanning electron microscopy (SEM) and UV-Vis. Also, the results were compared with the pure synthesized ZnO and WO3 NPs. Non-linear optical properties of the synthesized composite were measured using the Z-scan technique with a continuous wave Nd-Yag laser. The negative non-linear absorption coefficient of the components was obtained which indicates that the saturation absorption occurred in this composite. In comparison with pure ZnO NPs, non-linear absorption decreases which can be attributed to the negligible optical response of WO3 structures. Also, the negative value of the close aperture Z-scan curve shows that the thermal lensing effect is the main reason for the third-order non-linear refraction.

    Abstract Background/importance: Ultrasound (US)-guided cervical selective nerve root injections (CSNRI) have been proposed as an alternative to fluoroscopic (FL) -guided injections. When choosing US guidance, the proceduralist should be aware of potential issues confirming vertebral level, be clear regarding terminology, and up to date regarding the advantages and disadvantages of US-guided CSNRI.
    Objective: Review the accuracy and effectiveness of US guidance in avoiding vascular puncture (VP) and/or intravascular injection (IVI) during CSNRI.
    Evidence review: Queries included PubMed, CINAHL and Embase databases from 2005 to 2019. Three authors reviewed references for eligibility, abstracted data, and appraised quality.
    Findings: The literature demonstrates distinct safety considerations and limited evidence of the effectiveness of US guidance in detecting VP and/or IVI. As vascular flow and desired injectate spread cannot be visualized with US, the use of real-time fluoroscopy, and if needed digitial subraction imaging, is indicated in cervical transforaminal epidural injections (CTFEIs). Given the risk of VP and/or IVI, the ability to perform and to retain FL images to document that the procedure was safely conducted is valuable in CTFEIs.
    Conclusion: US guidance remains to be proven as a non-inferior alternative to FL guidance or other imaging modalities in the prevention of VP and/or IVI with CTFEIs or cervical selective nerve root blocks. There is a paucity of adequately powered clinical studies evaluating the accuracy and effectiveness of US guidance in avoiding VP and/or IVI. US-guided procedures to treat cervical radicular pain has limitations in visualization of anatomy, and currently with the evidence available is best used in a combined approach with FL guidance.

    Abstract Introduction and importance: Pseudomeningocele formation from incidental durotomy is a known risk in spine surgery. We present a case of incidental durotomy leading to anterior neck pseudomeningocele, compressing the carotid body (CB) resulting in syncopal episodes. To our knowledge, this is the first case report implicating syncopal episodes to CB compression via a pseudomeningocele.
    Case presentation: A mid sixty-year-old patient with history of obesity, hypertension, and diabetes presented with gait impairment and hand weakness. Ossification of posterior longitudinal ligament (OPLL) was diagnosed with computed tomography imaging (CT) and magnetic resonance imaging (MRI). Elective surgery was completed with an anterior and posterior approach for decompression and fusion. Hospital course (San Jose, CA, USA) was complicated by respiratory depression and incomplete tetraplegia. On post-operative day (POD) six, CT revealed anterolateral soft tissue neck swelling; subsequent CT and MRI showed fluid collection expansion, with associated syncopal episodes on POD thirty-nine. Despite interventional radiology drainage, the fluid collection and symptoms returned five days later. The patient ultimately underwent durotomy revision and repair with muscle patch.
    Clinical discussion: This case highlights the challenges in managing anterior cervical dural tears resulting in pseudomeningocele. Risk factors include anterior cervical corpectomy and decompression, as well as an underlying diagnosis of OPLL. Untreated dural tears may develop into pseudomeningoceles which can contribute to life-threatening outcomes.
    Conclusion: This case report presents the serious consequences of incidental durotomy, the unique post-surgical complication of syncope due to compression of the CB from a pseudomeningocele, and the challenges of managing a persistent pseudomeningocele.
