Object Brain injury from preterm birth predisposes children to cerebral palsy, epilepsy, cognitive delay, and behavioral abnormalities. The CNS often begins before the early birth, which hinders diagnosis concurrent treatment. Safe, effective postnatal interventions are urgently needed minimize these chronic neurological deficits. Erythropoietin (EPO) is a pleiotropic neuroprotective cytokine, but biological basis of its efficacy in damaged developing brain remains unclear. Coordinated...
S-2 alar-iliac (S2AI) screws are an attractive alternative to conventional fixation with iliac bolts because they lower profile, require less muscle dissection, and have greater pullout strength. Few studies, however, compare outcomes between these techniques.The authors conducted a retrospective cohort study of consecutive adult patients at single institution from December 2009 March 2012 who underwent lumbopelvic using S2AI or bolts. Medical records were reviewed for clinical failure,...
Introduction Preliminary studies suggest that flow-diverting stents may be suitable for the treatment of aneurysms posterior circulation. The safety and efficacy using vertebral artery (VA) is not well defined. Objective To examine fate covering inferior cerebellar (PICA) in patients undergoing placement a stent VA aneurysm. Methods Consecutive who underwent Pipeline Embolization Device (PED) an aneurysm V4 segment between April 2012 June 2015 at our institution were retrospectively...
Recent literature describing complications associated with spinopelvic fixation iliac screws in adult patients has been limited but suggested high complication rates. The authors' objective was to report their experience screw a large series of 2-year minimum follow-up.
BACKGROUND AND OBJECTIVES: Advanced diffusion-weighted MRI (DWI) modeling, such as diffusion tensor imaging (DTI) and basis spectrum (DBSI), may help guide rehabilitation strategies after surgical decompression for cervical spondylotic myelopathy (CSM). Currently, however, postoperative DWI is difficult to interpret, owing signal distortions from spinal instrumentation. Therefore, we examined the relationship between DTI/DBSI—extracted rostral C3 level—and clinical outcome measures at 2-year...
Study Design: Prospective cohort study. Objective: To provide a primer of the glymphatic system, discuss its potential relevance in evaluating spinal diseases like cervical spondylotic myelopathy (CSM), and describe possible imaging markers system derived from advanced diffusion-weighted (dMRI), namely diffusion tensor (DTI) basis spectrum (DBSI). Summary Background Data: The is recently described physiological process that plays an integral role macroscopic waste clearance CNS through...
The goal of this study was to gain understanding about patients' perspectives on decision making in the context invasive medical interventions and whether decision-making preferences influenced type information they desired be provided by physicians.Questionnaire consecutive patients a university-based general medicine clinic.Patients were presented with randomized list three types that physicians could provide (risk, benefit physician's opinion should undergo procedure). Patients asked...
S2-alar-iliac (S2AI) screws are 1 technique for lumbopelvic fixation to improve fusion rates across the lumbosacral junction that has gained wider acceptance. The S2AI screw crosses cortical surfaces of sacroiliac joint (SIJ), which may biomechanical strength instrumentation.To report preliminary radiographic outcomes patients who underwent with a minimum 12-month follow-up.We retrospectively reviewed adult screws. Patients computed tomography (CT) scans obtained preoperatively and ≥12...
BACKGROUND AND IMPORTANCE: As the use of flow-diverting stents (FDSs) for intracranial aneurysms expands, a small number case reports have described successful treatment blister internal carotid artery with flow diversion. Blister are uncommon and fragile lesions that historically high rates morbidity mortality despite multiple strategies. We report rebleeding after ruptured aneurysm deployment single FDS. CLINICAL PRESENTATION: A 29-year-old man presented subarachnoid hemorrhage dorsal...
Surgical arthrodesis for pediatric occipitocervical (OC) instability has a high rate of success in wide variety challenging circumstances; however, identifying potential risk factors can help to target variables that should be the focus improvement. The aim this paper was examine predictive failure population patients who underwent instrumented OC using uniform surgical philosophy.The authors conducted retrospective cohort study fusion from 2001 2013 at single institution determine failure,...
OBJECTIVEFixed sagittal spinal malalignment is a common problem in adult deformity (ASD). Various three-column osteotomy techniques, including the extended pedicle subtraction (ePSO), may correct global and regional this patient population. In contrast to number of reports on traditional PSO (Schwab grade 3 osteotomy), there limited literature outcomes ePSO 4 osteotomy) ASD surgery. The objective retrospective study was provide focused investigation radiographic complications single-level...
To assess how patients' preferences for non-numerical risk information are related to their tendency choose early surgical treatment asymptomatic gland-confined prostate cancer (a choice with high and therapeutic uncertainty), the authors conducted a cross-sectional study of 228 patients receiving continuing care in gen eral medicine clinic. After being provided three data disclosures decision, subjects were given between surgery-now watchful waiting. Data about complications presented...
Object Despite the popularity of flow-diverting stents for treatment cerebral aneurysms, there is no widely accepted scale characterization results. We present an outcomes-based grading that considers factors related to failure flow diversion. Methods The was developed using results from consecutive patients at two institutions who were treated with diversion a aneurysm. initial graded on patient, aneurysm, and characteristics. A 6-point based these data. Results One hundred seventy-one...
After a far-lateral transcondylar approach, patients may maintain neutral alignment in the immediate postoperative period, but severe occipitoatlantal subluxation occur gradually with cranial settling and possible neurological injury. Previous research is based on assumptions regarding extent of condylar resection change biomechanics that produces instability.To quantify bone removal during determine changes range motion (ROM) stiffness after resection, identify threshold predicts...
Abstract Purpose There is limited information on the clustering or co-occurrence of complications after spinal fusion surgery for neuromuscular disease in children. We aimed to identify frequency and predictive factors co-occurring perioperative these Methods In this retrospective database cohort study, we identified children (ages 10–18 years) with scoliosis who underwent elective 2012–2020 from National Surgical Quality Improvement Program-Pediatric database. The rates within 30 days were...
OBJECTIVE Flow-diverting devices have been used for the treatment of complex intracranial vascular pathology with success, but role these in treating iatrogenic injuries has yet to be clearly defined. Here, authors report their bi-institutional experience use Pipeline embolization device (PED) injuries. METHODS The reviewed a retrospective cohort patients vasculature that were treated PED between 2012 and 2016. Data collection included demographic data, indications treatment, number sizes...
