    Abstract Background: Multimodal perioperative pain management including nonopioid analgesia is a major pillar of enhanced recovery after surgery programs. The aim of this study was to investigate the analgesic efficacy of the preoperative combination of 2 nonopioid drugs, oral pregabalin and intravenous magnesium sulfate, in patients undergoing posterolateral lumbar spinal fusion.
    Methods: This 4-arm, randomized, double-blind, placebo-controlled trial included 104 patients randomly allocated to receive: magnesium sulfate and pregabalin (MP), magnesium sulfate and oral placebo (M), 0.9% saline and oral pregabalin (P), and 0.9% saline and oral placebo (C). The study drugs were administered 1 hour preoperatively. The primary outcome was the cumulative morphine consumption on postoperative day 1. Secondary outcomes included visual analog scale scores for leg pain at rest and with movement, and postoperative nausea and vomiting (PONV) in the first 48 hours after surgery.
    Results: Cumulative morphine consumption on postoperative day 1 was lower in group MP (19.6±8.0 mg) compared with group M (32.6±9.5 mg; P <0.001), group P (28.9±9.4 mg; P =0.001), or group C (38.8±10.3 mg; P <0.001). Multiple linear regression demonstrated a significant association between group MP and cumulative morphine consumption (B=-5.4 [95% CI, -7.1, -3.7], P <0.001). Visual analog scale scores for leg pain at rest and with movement were lower in group MP compared with other groups ( P =0.006 and <0.001). The incidence of PONV was also lowest in group MP ( P =0.032).
    Conclusions: Preoperative administration of oral pregabalin and intravenous magnesium sulfate resulted in reduced morphine consumption and greater analgesic effect than the use of each drug individually or placebo in patients undergoing posterolateral lumbar spinal fusion.

    Abstract Background and objectives: No study has evaluated the efficacy of using preoperative antiseptic dressings in reducing the rate of surgical site infection (SSI) in spine surgery thus far. To investigate the efficacy of the use of preoperative povidone-iodine-impregnated antiseptic dressings in patients undergoing instrumented posterolateral lumbar spinal fusion.
    Methods: This was a randomized, nonblinded, active-controlled, parallel-group clinical trial. Patients were randomly assigned to the 2 study groups, including treatment and control. Patients in the treatment group received povidone-iodine-impregnated antiseptic dressing applied to the anticipated incision site 12 hours before the operation. The control group merely received the standard perioperative care with no additional intervention or placebo. Patients were followed up for 90 days, and SSIs were recorded.
    Results: A total of 200 patients were included in this study (100 in each arm). Three cases of SSI were observed in the treatment group compared with 12 in the control one. A significant reduction in the postoperative rate of SSI was observed in the treatment group compared with the control one (P = .029). In addition to study intervention (P = .029), body mass index (P = .005), smoking status (P = .005), duration of the procedure (P = .003), American Society of Anesthesiologists class (P = .002), and diabetes mellitus (P < .001) were significantly associated with the postoperative rate of SSI.
    Conclusion: To the best of our knowledge, this study for the first time showed that preoperative use of antiseptic dressings is significantly effective in reducing the rate of SSI in instrumented posterior lumbar spinal fusion surgery. Future studies are warranted to evaluate the efficacy of different preparations or the effectiveness of the present one in patients undergoing spine procedures with other surgical characteristics.

    Abstract Background: Some previous reports have shown a reduced number of admission in stroke cases during the coronavirus disease 2019 (COVID-19) pandemic period. The present study aimed to investigate this changing pattern and the potential causes behind it at an academic neurology and neurosurgery center in Iran.
    Methods: Patients admitted to our center with the diagnosis of ischemic and hemorrhagic stroke, between March 1, 2019, Jun 1, 2019, and the similar 3-month period in 2020 (COVID-19 pandemic period), were compared in terms of clinical characteristics and outcome. Poisson regression was also conducted to assess the correlation between daily admissions and the COVID-19 pandemic period.
    Results: A total of 210 patients with stroke (ischemic and hemorrhagic) in 2019 were compared with 106 patients in 2020. COVID-19 pandemic period was significantly associated with the decline in the number of daily admissions in ischemic stroke (IRR, 0.51 [95% CI, 0.4-0.64]). A significant reduction (P = 0.003) in time from onset to arrival at hospital from median 12 h [IQR, 5-32] in 2019 to median 6 h [IQR, 4-16] in 2020 was found in ischemic stroke cases. National Institute of Health Stroke Scale (NIHSS) was significantly increased (P < 0.001) from median 4 [IQR, 2-7] in 2019 to median 9 [IQR, 4-14] in 2020. Glasgow coma scale (GCS) was significantly decreased from 13.9 (SD, 2) in 2019 to 12.8 (SD, 2.9) in 2020 (P < 0.001).
    Conclusions: The present study provided new pieces of evidence regarding the changed pattern of hospital admission in stroke especially the possible reasons for its decline.

    Abstract Objective: The coronavirus disease 2019 (COVID-19) pandemic has considerably affected surgical practice. The present study aimed to investigate the effects of the pandemic on neurosurgical practice and the safety of the resumption of elective procedures through implementing screening protocols in a high-volume academic public center in Iran, as one of the countries severely affected by the pandemic.
    Methods: This unmatched case-control study compared 2 populations of patients who underwent neurosurgical procedures between June 1, 2019 and September 1, 2019 and the same period in 2020. In the prospective part of the study, patients who underwent elective procedures were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection postoperatively to evaluate the viability of our screening protocol.
    Results: Elective and emergency procedures showed significant reduction during the pandemic (59.4%, n = 168 vs. 71.3%, n = 380) and increase (28.7%, n = 153 vs. 40.6%, n = 115, respectively; P = 0.003). The proportional distribution of neurosurgical categories remained unchanged during the pandemic. Poisson regression showed that the reduction in total daily admissions and some categories, including spine, trauma, oncology, and infection were significantly correlated with the pandemic. Among patients who underwent elective procedures, 0 (0.0%) and 26 (16.25%) had positive test results on days 30 and 60 postoperatively, respectively. Overall mortality was comparable between the pre-COVID-19 and COVID-19 periods, yet patients with concurrent SARS-CoV-2 infection showed substantially higher mortality (65%).
    Conclusions: By implementing safety and screening protocols with proper resource allocation, the emergency care capacity can be maintained and the risk minimized of hospital-acquired SARS-CoV-2 infection, complications, and mortality among neurosurgical patients during the pandemic. Similarly, for elective procedures, according to available resources, hospital beds can be allocated for patients with a higher risk of delayed hospitalization and those who are concerned about the risk of hospital-acquired infection can be reassured.

    Abstract Background: Despite the abundant literature on the use of selective dorsal rhizotomy (SDR) in spastic cerebral palsy, no investigation has evaluated its use in adult patients with chronic spinal cord injury (SCI)-induced spasticity. The present investigation aimed to evaluate the safety and potential efficacy of SDR in chronic SCI-induced spasticity for the first time.
    Methods: In this open-label, single-arm, non-randomized clinical trial, all patients were assigned to the single study intervention arm and underwent SDR. The primary outcome measure was the safety profile of SDR. Secondary outcome measures were Modified Ashworth Scale, Penn Spasm Frequency Scale, visual analog scale for spasticity, Spinal Cord Injury Spasticity Tool, Spinal Cord Independence measure version III, and Short Form 36 Health Survey Questionnaire.
    Results: Six patients with cervical SCI and 4 with thoracic SCI were allocated to the single study intervention arm. No adverse event attributable to the SDR was found. Moreover, all secondary outcome measures of the study improved significantly over the study period (P < 0.001). Multiple regression analysis also found a significant association between level of injury and changes in average Modified Ashworth Scale scores (P = 0.041), Spinal Cord Injury Spasticity Tool score (P = 0.013), and Spinal Cord Independence measure version III total (P = 0.002) and mobility domain scores (P = 0.004) at 12-month postoperatively.
    Conclusions: This clinical trial indicated that SDR is a safe and potentially effective procedure in patients with severe and intractable SCI-induced spasticity. However, future clinical trials with larger sample sizes and adequate power are required to validate our findings regarding efficacy.

    Abstract Objective: Prior evidence has supported the use of local intraoperative epidural steroids in lumbar discectomy for improvements in postoperative pain and outcomes. However, currently there is a paucity of data regarding the efficacy of local epidural steroids in spinal fusion procedures. The present investigation aimed to evaluate the impact of local epidural administration of triamcinolone acetonide-soaked Gelfoam on postoperative pain and patient-reported outcomes in patients undergoing instrumented posterolateral lumbar spinal fusion.
    Methods: In this randomized, double-blind, placebo-controlled trial, patients were randomly divided into two groups (treatment and control). Patients in the treatment group received a Gelfoam carrier soaked in 1 ml of triamcinolone acetonide (40 mg), which was placed over the nerve roots in the epidural space before the closure. Patients in the control group received a Gelfoam carrier soaked in normal saline in a similar fashion to the treatment group. Patients were followed up during their hospital stay and at 4 and 12 weeks postoperatively. The primary outcome measure was early postoperative visual analog scale (VAS) scores for pain both at rest and with movement.
    Results: A total of 100 patients were recruited in this study and were randomly allocated to the treatment or control group. No significant difference was found in baseline demographic, clinical, and surgical characteristics between the two groups. Postoperative VAS scores for pain both at rest and with movement were comparable between the treatment and control groups. Cumulative morphine consumption, length of hospital stay, and incidence of postoperative complications such as surgical site infection were also similar between the two groups. There was no significant difference in patient-reported outcomes including VAS scores for back and leg pain as well as the Oswestry Disability Index at 4 and 12 weeks postoperatively. The proportion of patients who achieved a minimum clinically important difference for patient-reported outcomes were also similar between the two groups.
    Conclusions: In contrast to the existing literature on the beneficial use of local intraoperative epidural steroids in conventional lumbar discectomy, the present study did not demonstrate such significant efficacy for the use of local epidural steroids in instrumented posterolateral lumbar spinal fusion. However, there is still a lack of evidence in this regard and further high-quality clinical trials are required to evaluate the efficacy of local epidural steroids in this group of patients.

    Abstract Background: Neurogenic bowel dysfunction (NBD) caused by spinal cord injury (SCI) is a major life limiting issue for many patients. However, studies detailing the factors contributing to bowel problems are scarce. The aim of this cross-sectional questionnaire-based study was to evaluate the associations between different aspects of bowel problems and characteristics of SCI, such as time since injury (TSI), level of injury (LOI), and the cause of injury. Methods: Two questionnaires (the NBD score questionnaire and the Cleveland clinic constipation system score questionnaire) were administered to complete, traumatic patients with SCI that matched the designated criteria. The total scores and the subscales were then regressed to TSI and LOI, and the distribution patterns of NBD score severity according to LOI and cause of injury were shown in a diagram. Results: Within the subscales of the NBD score, frequency of defecation, digital stimulation or evacuation of the anorectum, and perianal skin problems were all significantly and positively correlated with the TSI, yet the frequency of fecal incontinence was negatively associated with this variable. Moreover, uneasiness, headache, or perspiration during defecation and regular use of drops against constipation were negatively associated with the LOI. In the diagrams, patterns of NBD score severity were similar according to LOI, but visibly differed according to cause. With respect to the CCCS score (Cleveland Clinic Constipation Scoring System), the score itself was shown to be positively associated with TSI. Within the subscales, difficulty, time spent in lavatory, and duration of constipation were positively correlated with TSI. Furthermore, type of assistance was negatively associated with the LOI. Conclusion: Different characteristics of SCI, TSI, LOI, and cause, each are significantly and distinctly associated with different aspects of the bowel problems that patients with SCI face.

    Abstract Introduction: The prognosis for glioblastoma multiforme (GBM), a malignant brain tumor, is poor despite recent advancements in treatments. Suicide gene therapy is a therapeutic strategy for cancer that requires a gene to encode a prodrug-activating enzyme which is then transduced into a vector, such as mesenchymal stem cells (MSCs). The vector is then injected into the tumor tissue and exerts its antitumor effects.
    Case presentation: A 37-year-old man presented to our department with two evident foci of glioblastoma multiforme at the left frontal and left parietal lobes. The patient received an injection of bone marrow-derived MSCs delivering the herpes simplex virus thymidine kinase (HSV-tk) gene to the frontal focus of the tumor, followed by ganciclovir administration as a prodrug for 14 days. For follow-up, the patient was periodically assessed using magnetic resonance imaging (MRI). The growth and recurrence patterns of the foci were assessed. After the injection on 09 February 2019, the patient's follow-up appointment on 19 December 2019 MRI revealed a recurrence of parietal focus. However, the frontal focus had a slight and unremarkable enhancement. On the last follow-up (18 March 2020), the left frontal focus had no prominent recurrence; however, the size of the left parietal focus increased and extended to the contralateral hemisphere through the corpus callosum. Eventually, the patient passed away on 16 July 2020 (progression-free survival (PFS) = 293 days, overall survival (OS) = 513 days).
    Conclusion: The gliomatous focus (frontal) treated with bone marrow-derived MSCs carrying the HSV-TK gene had a different pattern of growth and recurrence compared with the non-treated one (parietal).
