The result of hysteroscopic area of interest resection weighed against Levonorgestrel-releasing intrauterine unit in postmenstrual recognizing inside patients which has a symptomatic area of interest from the uterine cesarean scar tissue: A potential cohort examine.
Pedestrian avoidance algorithms often tacitly assume that the maneuver which minimizes collisions will also be the safest maneuver. This work shows that this is not always the case when considering pedestrian fatalities. Given the unavoidable uncertainty in vehicle motion, environmental parameters, and pedestrian behavior, emergency avoidance maneuvers often involve some chance of a collision. Maneuvers that aim to keep the vehicle as far away from the pedestrian as possible will theoretically minimize collisions; but if this strategy is followed and a collision occurs nonetheless, it will often be at a higher speed than would occur with alternative strategies. This is a result of the tires' friction ellipse which enforces a constraint between steering versus braking; for collision avoidance, braking must be reduced if pedestrian clearance is to be maximized. GPCR inhibitor This work shows that in some common pedestrian collision situations, the net effect of this increase in vehicle speed for pure avoidance offsets the benefits of reducing collisions. Pedestrians, if hit, would be hit at higher speeds leading to a net reduction in pedestrian survivability for collision-minimizing maneuvers. First, this trend is demonstrated and explained using a simplified point-mass model of a vehicle, which is then verified with a higher-fidelity vehicle model as well as experimental maneuvers with an instrumented vehicle. While real accidents involve dozens of important parameters, this research provides a general framework for an under-recognized effect under certain common conditions. The implication of this finding suggests that future research in pedestrian avoidance should consider fatality minimization as an alternative objective to collision minimization. BACKGROUND Cervical teardrop fractures are hyper-flexion and axial loading injuries associated with significant ligamentous disruption. Patients sustaining these types of injury are classically treated with a cervical corpectomy and anterior fusion. However, there are notable disadvantage of this approach, namely, disruption of the patient's true anatomic alignment and a reduction in the number of fixation points available for cervical fusion. Here we present a novel method of open reduction and internal fixation in a neurologically-intact patient with cervical teardrop fracture. CASE DESCRIPTION A 34 year old male presented to Ryder Trauma Center after a helmeted motorcycle accident. The patient was found to be neurologically intact upon arrival and imaging demonstrated a C5 teardrop fracture without bony retropulsion. The patient was taken to the OR for an open reduction and internal fixation of the fracture using a novel technique. This technique utilized traditional diskectomies at the C4-5 and C5-6 levels, along with a temporary, unicortical screw into the C5 body to capture the anteriorly displaced fragment. A bicortical screw was then placed into the contralateral side, and, now, having fully reduced the fracture, the first (temporary) screw was replaced with a bicortical screw. The patient was neurologically-intact post-operatively with 2 month followup CT demonstrating stable reduction of the fracture. CONCLUSIONS Here we present a novel technique for open reduction and internal fixation of a cervical teardrop fracture that does not require cervical corpectomy. This technique is particularly useful in patients with an anteriorly displaced fragment and without neurological deficit or compromise. OBJECTIVE The process of fellowship selection remains unclear and heterogeneous among subspecialties in neurosurgery. We surveyed neurosurgical residents applying for subspecialty fellowships about their experiences to evaluate the process and find areas for improvement. METHODS We distributed an online, nationwide survey to 153 U.S. neurosurgical residents (postgraduate years 5-7) identified via the American Association of Neurological Surgeons resident database. RESULTS Sixty-nine residents responded to the survey representing a variety of subspecialties. Most residents applied for 2-5 programs (45%) and completed 2-5 interviews (45%). The primary methods of finding fellowships were via word of mouth (68%) and faculty mentors (67%), followed by websites and reaching out to fellowship directors (54%) and online database searching (46%). Although many residents applied for fellowships in postgraduate year 5 of training (39%), there was significant variability in times for interviews and offer letters. Most residents accepted their first offer (75%). Most respondents (93%) thought that national neurosurgical societies should help improve the fellowship application process with reasons including a common application and due dates (29%), fellowship database with program details (29%), and improved coordination of interviews (23%). In regards to a nationalized match system, residents were roughly split among opposed (38.6%), neutral (26.3%), and supportive (35.1%). CONCLUSIONS These survey results suggested that the neurosurgical fellowship application process could be improved by a common application, public listing of programs, standardized dates for application, and improved coordination of interviews. Residents are generally supportive of having an improved organization of the match and/or a national fellowship match. BACKGROUND Low back pain is a common complaint during pregnancy. However, spinal pathologies, which manifest with severe pain, radiculopathy and acute neurological deficits due to disc herniation or mass lesions require special attention. Here, we present our interdisciplinary experience in the surgical management of spinal emergencies during pregnancy. MATERIALS AND METHODS The data of pregnant women who underwent surgery for spinal pathologies over a 10-year period were collected. Patient-related characteristics such as maternal age, gestational age, preoperative work-up, signs and symptoms of mothers, and diagnostic procedures were evaluated. After an interdisciplinary conference individualized treatment plans with regard to available options were developed. Fetal Doppler and cardiotocography were obtained before and after surgery. RESULTS Nine pregnant women presented with spinal disorders and underwent spinal emergency surgery within the study period. The mean maternal age was 32.2 years. Six women presented with lumbar disc herniations manifesting as severe sciatica or foot drop and three patients with thoracic mass lesions resulting in cauda equine syndrome and/or ataxia.
