OBJECTIVE To determine if Menière's disease is associated with fluctuations in afferent excitability in four human subjects previously implanted with vestibular stimulators. STUDY DESIGN Longitudinal repeated measures. SETTING Tertiary referral center, human vestibular research laboratory. PATIENTS Four human subjects with previously uncontrolled Menière's disease unilaterally implanted in each semicircular canal with a vestibular stimulator. One subject had only two canals implanted. check details INTERVENTION(S) Repeated measures of electrically-evoked slow phase eye velocity and vestibular electrically-evoked compound action potentials (vECAP) over 2 to 4 years. MAIN OUTCOME MEASURE(S) Slow phase eye velocity and N1-P1 vECAP amplitudes as a function of time. RESULTS There were statistically significant fluctuations in electrically evoked slow phase eye velocity over time in at least one semicircular canal of each subject. vECAP N1-P1 amplitudes measured at similar time intervals and stimulus intensities seem to show somewhat correlated fluctuations. One of the subjects had a single Menière's attack during this time period. The others did not. CONCLUSIONS In these four subjects originally diagnosed with Menière's disease, there was fluctuating electrical excitability of the ampullar nerve of at least one canal in each subject. These fluctuations occurred without active symptoms of Menière's disease.BACKGROUND Postdischarge nausea and vomiting after ambulatory surgery is a common problem that is not adequately addressed in current practice. This prospective, randomized, double-blind, parallel-group, placebo-controlled study was designed to test the hypothesis that oral olanzapine is superior to placebo at preventing postdischarge nausea and vomiting. METHODS In a single-center, double-blind, randomized, placebo-controlled trial, the authors compared a single preoperative dose of olanzapine 10 mg to placebo, in adult female patients 50 years old or less, undergoing ambulatory gynecologic or plastic surgery with general anesthesia. All patients received standard antiemetic prophylaxis with dexamethasone and ondansetron. The primary composite outcome was nausea and/or vomiting in the 24 h after discharge. Secondary outcomes included severe nausea, vomiting, and side effects. RESULTS A total of 140 patients were randomized and evaluable. The primary outcome occurred in 26 of 69 patients (38%) in the placebo mmon despite use of current antiemetics. WHAT THIS ARTICLE TELLS US THAT IS NEW The authors randomized women having day surgery to olanzapine 10 mg or placebo. All were also given both dexamethasone and ondansetron.Olanzapine reduced nausea and vomiting in the 24 h after hospital discharge from 38% to 14%, corresponding to a number-needed-to-treat of just four patients.The Coronavirus Disease 2019 (COVID-19) pandemic has thus far caused a total of 81,747 confirmed cases with 3,283 deaths in China, and more than 370,000 confirmed cases including over 16,000 deaths around the world by March 24, 2020. This issue has received extensive attention from the international community and has become a major public health priority. As the pandemic progresses, it is regrettable to know the healthcare workers, including anesthesiologists, being infected constantly. Therefore, we would like to share our firsthand practical experience and perspective in China, focusing on the personal protection of healthcare workers and the risk factors related to their infection, based on the different stages of the COVID-19 epidemic in China.BACKGROUND Combat-related pelvic ring injuries frequently lead to placement of a temporizing external fixation device for early resuscitation and transport. These injuries are commonly complicated by concomitant polytrauma and extensive soft-tissue injuries, which may preclude early internal fixation and lead to prolonged use of external fixation. To date, few studies have reported on the outcomes of definitive external fixation for combat-related pelvic ring injuries. QUESTIONS/PURPOSES (1) In patients treated with definitive external fixation after combat-related pelvic ring injuries, how often is the quality of reduction within radiographically acceptable parameters at the end of treatment? (2) What proportion of patients demonstrate local heterotopic ossification after these injuries? (3) What patient- and treatment-related factors are associated with increased complications and pain? METHODS We retrospectively studied all patients with pelvic ring injuries treated at a tertiary military referral center fes. LEVEL OF EVIDENCE Level IV, therapeutic study.BACKGROUND Case reports suggest that there is an increased risk of subtrochanteric femur fracture after femoral neck fixation with cannulated screws when the distal-most screw is placed distal to the lesser trochanter. However, to our knowledge, there are no biomechanical data supporting this observation. QUESTIONS/PURPOSES (1) Is there an increased risk of subtrochanteric femur fracture after femoral neck fixation with cannulated screws in normal density and osteoporotic Sawbones when the distal-most screw is started distal to the lesser trochanter? (2) Does the screw starting point position after femoral neck fixation with cannulated screws affect load to failure when normal density and osteoporotic Sawbones are loaded through their mechanical axis? METHODS Normal density and osteoporotic Sawbones femora were instrumented with three cannulated screws in a triangular apex distal configuration with the distal-most screw starting either proximal to, at, or distal to the level of the lesser trochanter. check details Specimenotic subset. Additionally, there was decreased load to failure when the distal-most screw was started distal to the lesser trochanter. CLINICAL RELEVANCE These data suggest that avoiding a screw start point distal to the level of the lesser trochanter in femoral neck fracture fixation may decrease the risk of catastrophic subtrochanteric femur fractures, especially in patients with osteoporosis. However, it should be noted that a more overall varus screw alignment could theoretically compromise the ability to achieve compression across the fracture, with attendant implications with regard to fracture union in the acute setting.
