ObjectiveTo clarify the effect of visual system on the post-concussion dizziness by using virtual reality system (VR).Background: the post-concussion dizziness is most commonly reported and associated with prolonged symptom recovery. Therefore, the post-concussion dizziness is one of the most important issues.Design/MethodsThe study design was retrospective study. Facility is Toho University Ohashi Medical Center Neurosurgery Sports-related head injury clinic. The search period is April 2018 to February 2019. Inclusion criteria were as follows: 1) Sports-related head injury cases, 2) Physician-diagnosed Sports-related concussion, 3) Underwent evaluation by the same neurosurgeon, 4) More than 28 days continued follow-up. The examination items were as follows: 1) Age/sex, 2) Competition item, 3) The prediction score of persistent post concussive symptoms (PPCS) at the time of the first visit, 4) PPCS cases, 5) Reproducibility of symptoms by Virtual reality System, 6) The presence or absence of PPCS at the invasion after 60 days. Statistical analysis used t test.ResultsThe 18 SRC participants (Group VR: GVR) were selected and matched with 18 healthy controls (Group HC: GHC). The average Age of both GVR and GHC was 23.1 (16–30) vs 21.7 (16–31) years. The most majority competition item of GVR was Rugby football. The prediction score of PPCS (Low: Medium: High) of both groups was the same as 10: 8: 0 (p > 0.05, no significant). PPCS cases of both GVR and GHC were 12 vs 18 (p 0.05, no significant).ConclusionsOur result suggests that a certain number of post-concussion dizziness cases that include visual system elements, leading to prolongation of symptoms if appropriate therapeutic intervention is not performed.

ObjectiveTo evaluate the Sex differences in Sport-related Concussion in Japan.BackgroundWe dont't have the knowledge about the sex differences in SRC in Japan.Design/MethodsThe study design was retrospective study. Facility is Toho University Ohashi Medical Center Neurosurgery Sports-related head injury clinic. The search period is April 2017 to February 2018. Inclusion criteria were as follows: 1) Sports-related head injury cases, 2) Physician-diagnosed Sports-related concussion, 3) Underwent evaluation by the same neurosurgeon, 4) More than 28 days continued follow-up. The following items were compared male and female. The examination items were as follows: 1) Age/sex, 2) competition item, 3) prior concussion, 4) Migraine history, 5) persistent post concussive symptoms. Statistical analysis used t test.ResultsThe 140 selected cases were 114 male (Group M: GM) and 26 female (Group F: GF). The mean Age of both GM and GF was 20 years. The most majority competition item of GM was Rugby football. On the other hand, GF was lacrosse. 42 cases of GM and 9 cases of GF suffered prior concussion (p > 0.05, no significant). 19 cases of GM and 6 cases of GF had migraine history (p > 0.05, no significant). 37 cases of GM and 16 cases of GF had PPCS (p < 0.05).ConclusionsOur result suggests that female players explain the significant difference in the prevalence of PPCS in Japan.

The aim of this study was to investigate the effects of a virtual reality program combined with conventional therapy in upper limb function in people with tetraplegia and to provide data about patients’ satisfaction with the virtual reality system. Thirty-one people with subacute complete cervical tetraplegia participated in the study. Experimental group received 15 sessions with Toyra®virtual reality system for 5 weeks, 30 minutes/day, 3 days/week in addition to conventional therapy, while control group only received conventional therapy. All patients were assessed at baseline, after intervention, and at three-month follow-up with a battery of clinical, functional, and satisfaction scales. Control group showed significant improvements in the manual muscle test (p= 0,043, partialη2= 0,22) in the follow-up evaluation. Both groups demonstrated clinical, but nonsignificant, changes to their arm function in 4 of the 5 scales used. All patients showed a high level of satisfaction with the virtual reality system. This study showed that virtual reality added to conventional therapy produces similar results in upper limb function compared to only conventional therapy. Moreover, the gaming aspects incorporated in conventional rehabilitation appear to produce high motivation during execution of the assigned tasks. This trial is registered with EudraCT number2015-002157-35.

There have been a few case reports of head injury leading to brain tumour development in the same region as the brain injury. Here we report a case where the patient suffered a severe head injury with contusion. He recovered clinically with conservative management. Follow up Computed Tomography scan of the brain a month later showed complete resolution of the lesion. He subsequently developed malignant brain tumour in the same region as the original contusion within a very short period of 15 months. Head injury patients need close follow up especially when severe. The link between severity of head injury and malignant brain tumour development needs further evaluation. Role of anti-inflammatory agents for prevention of post traumatic brain tumours needs further exploration.

OBJECTIVEIn this study, the authors’ aim was to investigate whether obesity affects surgery rates for adjacent-segment degeneration (ASD) after transforaminal lumbar interbody fusion (TLIF) for spondylolisthesis.METHODSPatients who underwent single-level TLIF for spondylolisthesis at the University of California, San Francisco, from 2006 to 2016 were retrospectively analyzed. Inclusion criteria were a minimum 2-year follow-up, single-level TLIF, and degenerative lumbar spondylolisthesis. Exclusion criteria were trauma, tumor, infection, multilevel fusions, non-TLIF fusions, or less than a 2-year follow-up. Patient demographic data were collected, and an analysis of spinopelvic parameters was performed. The patients were divided into two groups: mismatched, or pelvic incidence (PI) minus lumbar lordosis (LL) ≥ 10°; and balanced, or PI-LL < 10°. Within the two groups, the patients were further classified by BMI (< 30 and ≥ 30 kg/m2). Patients were then evaluated for surgery for ASD, matched by BMI and PI-LL parameters.RESULTSA total of 190 patients met inclusion criteria (72 males and 118 females, mean age 59.57 ± 12.39 years). The average follow-up was 40.21 ± 20.42 months (range 24–135 months). In total, 24 patients (12.63% of 190) underwent surgery for ASD. Within the entire cohort, 82 patients were in the mismatched group, and 108 patients were in the balanced group. Within the mismatched group, adjacent-segment surgeries occurred at the following rates: BMI < 30 kg/m2, 2.1% (1/48); and BMI ≥ 30 kg/m2, 17.6% (6/34). Significant differences were seen between patients with BMI ≥ 30 and BMI < 30 (p = 0.018). A receiver operating characteristic curve for BMI as a predictor for ASD was established, with an AUC of 0.69 (95% CI 0.49–0.90). The optimal BMI cutoff value determined by the Youden index is 29.95 (sensitivity 0.857; specificity 0.627). However, in the balanced PI-LL group (108/190 patients), there was no difference in surgery rates for ASD among the patients with different BMIs (p > 0.05).CONCLUSIONSIn patients who have a PI-LL mismatch, obesity may be associated with an increased risk of surgery for ASD after TLIF, but in obese patients without PI-LL mismatch, this association was not observed.
