This retrospective study aimed to compare the patient-reported outcomes and radiographic assessment of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for degenerative spondylolisthesis with reduction versus in situ fusion. Patients receiving MI-TLIF with reduction were assigned as Group A, and those without reduction were assigned as Group B. Radiographic fusion was assessed using Bridwell's grading criteria. ⋯ However, there were no significant differences in JOA, VAS, and ODI between the two groups whenever preoperatively, or 3-month postoperatively, or at the last follow-up (p>0.05). According to MacNab criteria, the excellent and good rate was 85.37% in Group A and 86.49% in Group B (p=0.983). MI-TLIF is an effective and satisfactory surgical technique to manage degenerative spondylolisthesis regardless of reduction or not, so routine reduction may not be a requirement in MI-TLIF for degenerative spondylolisthesis.

Spinal tumors are conventionally differentiated based on location in relation to the spinal cord. Benign spinal tumors such as schwannomas and meningiomas are typically extra-axial (intradural extramedullary) lesions, whereas more aggressive primary spinal tumors such as ependymomas are typically intramedullary masses. Rarely, ependymomas can have both intramedullary and extramedullary components (typically referred to as exophytic ependymomas). ⋯ Histopathological examination confirmed ependymoma with World Health Organization grade II/IV. Pre-operative suspicion of an exophytic ependymoma influences operative planning and clinical management. We review the literature and discuss clinical management strategies for these interesting spinal tumors.

Traumatic atlanto-occipital dislocation (AOD) is an ominous injury with high mortality and morbidity in trauma patients. Improved survival has been observed with advancements in pre-hospital and hospital care. Furthermore, high quality imaging studies are accessible at most trauma centers; these are crucial for prompt diagnosis of AOD. ⋯ We found that patients with TBI are eight times more likely to die than patients without TBI. A high degree of suspicion for AOD during pre-hospital care, as well as, prompt diagnosis and management in the trauma center play a key role in the treatment of this devastating injury. The relationship between survival and factors such as TBI and SCI should be further explored.

The purpose of this study was to explore the inter-device reliability of NPi-100 pupillometers (NeuroOptics, Inc.). The pupillary examination is a fundamental element of the neurological exam. Current evidence suggests that the traditional examination of the pupil with a hand held flashlight has limited inter-rater reliability. ⋯ There was no statistically significant difference between the mean maximum pupil size at rest, the minimum pupil size during light stimulation, and the mean pupil reactivity, for both the right and left eye, when assessed by two investigators, each with a different pupillometer. In addition, Cohen's Kappa assessments of pupil size and reactivity revealed an almost perfect agreement between the two pupillometers for the maximum pupil size, the minimum pupil size, and for pupil reactivity for both eyes. There is a high inter-device reliability of automated pupillary assessments by two practitioners examining the same patient using different NPi-100 pupillometers.

Stent-assisted coil embolization has been increasingly used to treat paraclinoid aneurysms. The study was aimed to evaluate safety and efficacy of stent-assisted coil embolization for paraclinoid aneurysms and explore the factors influencing the long-term outcomes. Under an institutional review board approved protocol, the clinical and angiographic data of 129 paraclinoid aneurysms in 120 patients (Male:Female=36:84; median age, 52years; range, 21-84) treated by stent-assisted coil embolization were reviewed retrospectively. ⋯ Multivariate logistic regression analysis found that ruptured aneurysms (odds ratio [OR]=5.893, 95% confidence interval [CI], 1.512-23.054; p=0.011), larger size (OR=2.339; 95%CI, 1.148-4.781; p=0.020) and hypertension (OR=6.143; 95%CI, 1.560-24.183; p=0.009) might be predictors of recurrence. Stent-assisted coil embolization of paraclinoid aneurysm has a risk of recurrence. Ruptured aneurysms, larger size and hypertension may be the risk factors for recurrence.
