A 36-year-old Egyptian women with both mitral and aortic valve bioprostheses and tricuspid annuloplasty became pregnant and was referred to our centre for very severe aortic prosthetic valve stenosis (mean gradient 87 mmHg) and New York Heart Association III dyspnea. Echocardiography revealed aortic bioprosthesis degeneration with patient-prosthesis mismatch. This is the first case reported about a pregnant women with a patient-prosthesis mismatch involving a bioprosthesis. MV1035 chemical structure The management is discussed and, in conclusion, a review of the literature performed.The inflammatory/immune response at the site of peripheral nerve injury participates in the pathophysiology of neuropathic pain. Nevertheless, little is known about the local regulatory mechanisms underlying peripheral nerve injury that counteract the development of pain. Here, we investigated the contribution of regulatory T (Treg) cells to the development of neuropathic pain by using a partial sciatic nerve ligation model (PSNL) in mice. We showed that Treg cells infiltrate and proliferate in the site of peripheral nerve injury. Local Treg cells suppressed the development of neuropathic pain mainly through the inhibition of the CD4 Th1 response. Treg cells also indirectly reduced neuronal damage and neuroinflammation at the level of the sensory ganglia. Finally, we identified IL-10 signaling as an intrinsic mechanism by which Treg cells counteract neuropathic pain development. These results revealed Treg cells as important inhibitory modulators of the immune response at the site of peripheral nerve injury that restrain the development of neuropathic pain. In conclusion, the boosting of Treg cell function/activity might be explored as a possible interventional approach to reduce neuropathic pain development after peripheral nerve damage.Propranolol is a non-selective beta-adrenergic receptor antagonist. A multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase 2b trial enrolled participants aged 18-65 years with temporomandibular disorder (TMD) myalgia to evaluate efficacy and safety of propranolol compared with placebo in reducing facial pain. Participants were randomized 11 to either extended-release propranolol hydrochloride (60 mg, BID) or placebo. The primary endpoint was change in facial pain index (FPI = facial pain intensity multiplied by facial pain duration, divided by 100). Efficacy was analyzed as a mean change in FPI from randomization to week 9 and as the proportion of participants with ≥30% or ≥50% reductions in FPI at week 9. Regression models tested for treatment-group differences adjusting for study site, sex, race, and FPI at randomization. Of 299 participants screened, 200 were randomized; 199 had at least one post-randomization FPI measurement and were included in intention-to-treat analysis. At week 9, model-adjusted reductions in mean FPI did not differ significantly between treatment groups (-1.8, 95%CL -6.2, 2.6; P=0.41). However, the proportion with a ≥30% reduction in FPI was significantly greater for propranolol (69.0%) than placebo (52.6%), and the associated number-needed-to-treat (NNT) was 6.1 (P=0.03). Propranolol was likewise efficacious for a ≥50% reduction in FPI (NNT=6.1, P=0.03). Adverse event rates were similar between treatment groups, except for more frequent fatigue, dizziness, and sleep disorder in the propranolol group. Propranolol was not different from placebo in reducing mean FPI but was efficacious in achieving ≥30% and ≥50% FPI reductions after 9 weeks of treatment among TMD participants.OBJECTIVE The aim of this study was to assess the effect of an enhanced recovery after surgery (ERAS) pathway on pain and opioid use following lung resection. SUMMARY BACKGROUND DATA A major component ERAS pathways is opioid-sparing analgesia; however, the effect on postoperative pain and opioid use in patients undergoing lung resection is unknown. METHODS Following implementation of an ERAS pathway for lung resection, 123 consecutive patients were identified. Patients were propensity-matched 11 with a group of consecutive patients (n = 907) undergoing lung resection before ERAS. Differences regarding in-hospital opioid consumption, discharge prescribing of opioids, and postoperative pain scores were examined. Morphine milligram equivalents were separately calculated including and excluding tramadol as an opioid medication. RESULTS There were no significant differences between matched patients regarding age, sex, performance status, receipt of preoperative treatment, extent of lung resection, or operative appventional management.OBJECTIVE To evaluate the performance changes after sequential bilateral cochlear implantation in a pediatric population of bimodal cochlear implant (CI) users. To evaluate the factors which influence the parental and recipient decision to discontinue hearing aid use and seek a second implant. STUDY DESIGN Retrospective case review, within-subject comparison. SETTING Tertiary referral center. PATIENTS Thirty-one pediatric ( less then 18 yr) bimodal CI users who underwent sequential bilateral CI. INTERVENTIONS Sequential bilateral CI. MAIN OUTCOME MEASURES Parental and/or recipient's reasons for discontinuing their hearing aid and pursuing a second implant, device usage from datalogs, speech understanding in the bimodal and bilateral CI condition. RESULTS Parents/patients were motivated to pursue sequential bilateral CI based on their positive performance with CI1, the expectation of further improvement with a second CI, and the prospect of having a second independently functional ear. In the bimodal condition, mean word recognition score (WRS), sentence recognition in quiet (SIQ), and sentence recognition in noise (SIN) scores were 87.4, 97.3, and 92.9% respectively. At 1-year post-sequential bilateral CI, the mean WRS, SIQ, and SIN score were 92.7, 98.7, and 97.7%, respectively. The improvement in bilateral CI speech scores compared with bimodal scores was statistically significant for WRS (p = 0.015). A ceiling effect limited the ability to detect further meaningful differences on speech perception testing. CONCLUSIONS The bilateral CI condition demonstrates equivalent or slightly superior performance compared with the bimodal condition. Several non-speech benefits were elicited from parents as reasons for pursuing a second implant. Close monitoring of the residual acoustic hearing, inquiring about the perceived benefits provided by the HA, and early counseling regarding the potential for sequential bilateral CI are important aspects in determining if and when a second implant is indicated.OBJECTIVE We analyzed the long-term changes in speech perception ability of pediatric cochlear implants (CIs) to evaluate the effect of the age at the time of surgery. STUDY DESIGN Retrospective. SETTING Tertiary care academic center. PATIENTS One hundred fourteen prelingually deaf children with CI use duration >10 years. MAIN OUTCOME MEASURES Categories of auditory performance (CAP) scores and monosyllabic word recognition scores using the Asan-Samsung Korean word list (ASK-WRS) and a conventional word list (KS-WRS) were the main outcomes. Outcomes were compared according to the age at surgery (group I, 1-2 yr; II, 2.1-3 yr; III, 3.1-7 yr; IV, 7.1-13 yr). RESULTS CAP scores reached plateaus at 2.6 to 3.3 years post-CI; groups I to III showed better scores than group IV. The maximum CAP score was obtained in all children of groups I to III and in 65% of group IV. ASK-WRSs reached plateaus at 3.2 to 4.8 years post-CI. Younger patients at CI operation showed better ASK-WRSs (97, 93, 90, and 54% in groups I-IV, respectively), but the differences were not significant (I versus II and II versus III). Ceiling effect (perfect score) was observed in early groups (67, 44, 30, and 0% in groups I-IV). KS-WRSs, which is a challenging test, reached plateaus at 7.2 to 8.4 years postsurgery with no ceiling effect. Early implantees showed significantly better scores (88, 82, 73, and 46% in groups I-IV). CONCLUSIONS Speech perception ability after CI showed audiological age-specific improvement evaluated by various test methods. The most challenging test demonstrated long-term performance differences by the age at CI operation.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. 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.
