Resection of a Dumbbell-Shaped Facial Nerve Schwannoma With Preservation of Facial Nerve Function Through the Extended Middle Fossa Approach: 2-Dimensional Operative Video
Authors: Almefty Kaith K , Bi Wenya Linda , Ibn Essayed Walid , Al-Mefty Ossama 
Published: September 2021

Abstract
Facial nerve schwannomas are rare and can arise from any segment along the course of the facial nerve.
1
Their location and growth patterns present as distinct groups that warrant specific surgical management and approaches.
2
The management challenge arises when the facial nerve maintains good function (House-Brackmann grade I-II).
3
Hence, a prime goal of management is to maintain good facial animation. In large tumors, however, resection with facial nerve function preservation should be sought and is achievable.
4,5

While tumors originating from the geniculate ganglion grow extradural on the floor of the middle fossa, they may extend via an isthmus through the internal auditory canal to the cerebellopontine angle forming a dumbbell-shaped tumor. Despite the large size, they may present with good facial nerve function. These tumors may be resected through an extended middle fossa approach with preservation of facial and vestibulocochlear nerve function.
The patient is a 62-yr-old man who presented with mixed sensorineural and conductive hearing loss and normal facial nerve function. Magnetic resonance imaging (MRI) revealed a large tumor involving the middle fossa, internal auditory meatus, and cerebellopontine angle.
The tumor was resected through an extended middle fossa approach with a zygomatic osteotomy and anterior petrosectomy.
6
A small residual was left at the geniculate ganglion to preserve facial function. The patient did well with hearing preservation and intact facial nerve function. He consented to the procedure and publication of images.

Authors: Santos Carlos , Velasquez Carlos , Esteban Jesus , Fernandez Leticia , Mandonnet Emmanuel , Duffau Hugues , Martino Juan 
Published: September 2021

Abstract
Transopercular approach to the insula is indicated for resection of insular low-grade gliomas, particularly for Yasargil's 3B, 5A, and 5B types. Nevertheless, the infrequent location and its challenging approach make it difficult to master the surgery. Consequently, a realistic laboratory training model might help to acquire key surgical skills.
In this video, we describe a cadaveric-based model simulating the resection of a temporo-insular low-grade glioma. Kingler's fixation technique was used to fix the cadaver head before injecting red and blue colorants for a realistic vascular appearance. Hemisphere was frozen for white matter tract dissection. Tractography and intraoperative eloquent areas were extrapolated from a glioma patient by using a neuronavigation system. Then, a fronto-temporal craniotomy was performed through a question mark incision, exposing from inferior temporal gyrus up to middle frontal gyrus. After cortical anatomic landmark identification, eloquent areas were extrapolated creating a simulated functional cortical map. Then, transopercular noneloquent frontal and temporal corticectomies were performed, followed by subpial resection. Detailed identification of Sylvian vessels and insular cortex was demonstrated. Anatomic resection limits were exposed, and implicated white matter bundles, uncinate and fronto-occipital fascicles, were identified running through the temporal isthmus. Finally, a temporo-mesial resection was performed.
In summary, this model provides a simple, cost-effective, and very realistic simulation of a transopercular approach to the insula, allowing the development of surgical skills needed to treat insular tumors in a safe environment. Besides, the integration of simulated navigation has proven useful in better understanding the complex white matter anatomy involved. Cadaver donation, subject or relatives, includes full consent for publication of the images.
For the purpose of this video, no ethics committee approval was needed. Images correspond to a cadaver head donation. Cadaver donation, subject or relatives, includes full consent for any scientific purposes involving the corpse. The consent includes image or video recording. Regarding the intraoperative surgical video and tractography, the patient gave written consent for scientific divulgation prior to surgery.
Emergencies in freestanding ambulatory surgery centre
Authors: Karlsson Elin , Jakobsson Jan G. 
Published: September 2021

Purpose of review
Ambulatory surgery is increasing, more procedures as well as more complex procedures are transferred to ambulatory surgery. Patients of all ages including elderly and more fragile are nowadays scheduled for ambulatory surgery. Enhanced recovery after surgery (ERAS) protocols are now developed for further facilitating readily recovery, ambulation, and discharge. Thus, to secure safety, a vigilant planning and preparedness for adverse events and emergencies is mandatory.

Recent findings
Proper preoperative assessment, preparation/optimization and collaboration between anaesthetist and surgeon to plan for the optimal perioperative handling has become basic to facilitate well tolerated perioperative course. Standard operating procedures for rare emergencies must be in place. These SOPs should be trained and retrained on a regular basis to secure safety. Check lists and cognitive aids are tools to help improving safety. Audit and analysis of adverse outcomes and deviations is likewise of importance to continuously analyse and implement corrective activity plans whenever needed.

Summary
The present review will provide an oversight of aspects that needs to be acknowledged around planning handling of rare but serious emergencies to secure quality and safety of care in freestanding ambulatory settings.
Patient safety education in anesthesia: current state and future directions
Authors: Harbell Monica W. , Methangkool Emily 
Published: September 2021

Purpose of review
Although patient safety is a core component of education in anesthesiology, approaches to implementation of education programs are less well defined. The goal of this review is to describe the current state of education in anesthesia patient safety and the ideal patient safety curriculum.

Recent findings
Anesthesiology has been a pioneer in patient safety for decades, with efforts amongst national organizations, such as the American Society of Anesthesiologists and the Anesthesia Patient Safety Foundation to disseminate key standards and guidelines in patient safety. However, few, if any strategies for implementation of a patient safety curriculum in anesthesiology exist.

Summary
Patient safety education is crucial to the field of anesthesiology, particularly with the advancement of surgical and anesthesia technologies and increasing complexity of patients and procedures. The ideal patient safety curriculum in anesthesiology consists of simulation, adverse event investigation and analysis, and participation in process improvement. Efforts in education must adapt with changing technology, shifts in the way anesthesia care is delivered, and threats to physician wellness. Future efforts in education should harness emerging platforms, such as social media, podcasts, and wikis.
Critical event debriefing: a checklist for the aftermath
Authors: Arriaga Alexander F. , Chen Yun-Yun K. , Pimentel Marc Philip T. , Bader Angela M. , Szyld Demian 
Published: September 2021

Purpose of review
Millions of perioperative crises (e.g. anaphylaxis, cardiac arrest) may occur annually. Critical event debriefing can offer benefits to the individual, team, and system, yet only a fraction of perioperative critical events are debriefed in real-time. This publication aims to review evidence-based best practices for proximal critical event debriefing.

Recent findings
Evidence-based key processes to consider for proximal critical event debriefing can be summarized by the WATER mnemonic: Welfare check (assessing team members’ emotional and physical wellbeing to continue providing care); Acute/short-term corrections (matters to be addressed before the next case); Team reactions and reflections (summarizing case; listening to team member reactions; plus/delta conversation); Education (lessons learned from the event and debriefing); Resource awareness and longer term needs [follow-up (e.g. safety/quality improvement report), local peer-support and employee assistance resources]. A cognitive aid to accompany this mnemonic is provided with the publication.

Summary
There is growing literature on how to conduct proximal perioperative critical event debriefing. Evidence-based best practices, as well as a cognitive aid to apply them, may help bridge the gap between theory and clinical practice. In this era of increased attention to burnout and wellness, the consideration of interventions to improve the quality and frequency of critical event debriefing is paramount.
Management of postoperative nausea and vomiting in adults: current controversies
Authors: Rajan Niraja , Joshi Girish P. 
Published: September 2021

Purpose of review
Postoperative nausea and vomiting (PONV) continue to plague the surgical patient population with an adverse impact on postoperative outcomes. The aim of this review is to critically assess current evidence for PONV management, including studies evaluating baseline risk reduction and antiemetic prophylaxis, to provide a pragmatic approach to prevention and treatment of PONV in routine clinical practice.

Recent findings
Multiple recent reviews and guidelines have been published on this topic with some limitations. In the current ERAS era, all patients irrespective of their PONV risk should receive two to three antiemetics for prophylaxis. Patients at a high risk of PONV [i.e. prior history of PONV, history of motion sickness, high opioid requirements after surgery (e.g. inability to use nonopioid analgesic techniques)] should receive three to four antiemetics for prophylaxis.

Summary
This review provides a practical approach to PONV prevention based on recent literature.
Association of Counseling and Psychotherapy on Retention in Medication for Addiction Treatment Within a Large Medicaid Population
Authors: Eren Kemal , Schuster James , Herschell Amy , Loveland David , Neimark Geoffrey , Mihalyo Mark , Hurford Matthew , Houck Patricia , Ryan Neal 
Published: September 2021

Objectives
Buprenorphine/naloxone is an effective medication for the treatment of opioid use disorder. Unlike methadone, which can only be dispensed in federally waived clinics and which must be combined with specific psychosocial treatment, buprenorphine can be dispensed by individual prescribers who have completed an 8-hour training program, with no requirement that patients receive concomitant psychotherapy. The objective of this study is to quantify the association of counseling and psychotherapy on retention in treatment. We also examine the effect of buprenorphine dosage on retention.

Methods
We examined a cohort of 4987 members of a not-for-profit managed care organization serving Medicaid members in 41 counties in Pennsylvania. This cohort was selected from all members who had a full year without any medication for opioid use disorder followed by initiation of treatment with buprenorphine/naloxone in 2016 to 2017 and who remained Medicaid eligible for at least 80% of the following 2 years. Outcomes were estimated using inverse probability weighted propensity scores.

Results
The addition of counseling and psychotherapy within the first 8 weeks of treatment was associated with greater total retention in treatment and there was a dose-response relationship. A 16 mg/d or greater dose of buprenorphine was also associated with greater retention.

Conclusions
These results provide support for an integrated approach to treating people with an opioid use disorder, through a combination of buprenorphine pharmacotherapy and targeted counseling and psychotherapy within the first 2 months of treatment.
Maternal Cannabis Use in the Perinatal Period: Data From the Pregnancy Risk Assessment Monitoring System Marijuana Supplement, 2016–2018
Authors: Sood Shefali , Trasande Leonardo , Mehta-Lee Shilpi S. , Brubaker Sara G. , Ghassabian Akhgar , Jacobson Melanie H. 
Published: September 2021

Objective
To estimate the prevalence of perinatal cannabis use (ie, before and/or during pregnancy); document the frequency, modes, and motivations for use; and identify predictors of perinatal cannabis use.

Methods
Six states in the Pregnancy Risk Assessment Monitoring System, a state-specific, population-based surveillance system, administered a supplemental questionnaire on perinatal cannabis use in 2016–2018. Women with live births were surveyed 2–6 months postpartum about behaviors ≤ 3 months preconception and during pregnancy. Demographic, psychosocial, and behavioral characteristics were examined in relation to perinatal cannabis use using multinomial regression models. Those who: (1) never used cannabis, (2) only used in preconception period, and (3) used in both preconception and prenatal periods were compared.

Results
Among 6428 respondents, 379 (5.8%) used cannabis pre-conceptionally only and 466 (4.4%) used in both the preconception and prenatal periods. Among those using prenatally, most reported smoking as their single mode (87.1%), with the two most common reasons being stress (83.8%) and nausea/vomiting (79.2%). Marital status, race/ethnicity, socioeconomic status, parity, and cigarette and alcohol use were significantly associated with perinatal cannabis use. Single (vs partnered) women were more likely to use cannabis prenatally (odds ratio = 2.4, 95% confidence interval: 1.5, 3.9) and non-Hispanic Black (vs White) women were less likely to use prenatally (odds ratio = 0.4, 95% confidence interval: 0.2, 0.8).

Conclusions
Using a population-based sample of US births in six states, several demographic, psychosocial, and behavioral characteristics were identified in relation to perinatal cannabis use. These data are valuable for counseling in prenatal care and investigations of health effects.
Clubfoot Activity and Recurrence Exercise Study (CARES)
Authors: EL-Banna Ghida , Baskar Danika , Segovia Nicole , Frick Steven 
Published: September 2021

Background:
Approximately half of treated clubfoot patients initially corrected with the Ponseti method experience relapse that requires additional treatment. The consequences of relapse on childhood activity levels have not been well studied. Ponseti noted lower functional ratings at 18-year follow-up in clubfoot patients who had undergone tibialis anterior tendon transfer for relapse.

Methods:
Clubfoot Activity and Recurrence Exercise study (CARES) is an observational, prospective cohort study that compares physical activity in 30 clubfoot patients without and with relapse. Eligible participants were 5 to 10 years old, diagnosed with idiopathic clubfoot at birth, and had not received any clubfoot treatment for at least 6 months before study. Recruitment for this study occurred in-person and through Facebook clubfoot groups. Consented participants wore Fitbits secured to their wrists for at least 14 days, and completed a demographic survey, Child Health Questionnaire (CHQ), and the clubfoot disease-specific instrument (CDSI). Participants’ daily activity was monitored through Fitabase.

Results:
Participants without and with clubfoot relapse had similar daily step counts, distance walked, and step intensities, except for moderately active step intensity, which was higher in the clubfoot relapse group. Total steps, total distance, distances (very active, moderately active), minutes (very active, fairly active), and lightly active intensity of steps were significantly higher for participants whose families earn more than $100,000 per year. Various physical activities and sports were reported by both groups in daily activity sheets. Neither demographics nor the CDSI or the CHQ scores significantly differed between the 2 groups. Step counts of children with clubfoot with or without relapse were similar to published levels for healthy children.

Conclusion:
Children with clubfoot initially treated with the Ponseti method who undergo treatment for relapse have comparable physical activity to those who have not relapsed. They also have comparable step counts to that of the general pediatric population. These reassuring findings can guide conversations with parents when addressing concerns regarding their children’s physical activity after treatment for relapse of clubfoot deformity.

Level of Evidence:
Level II—therapeutic studies—investigating the results of treatment.
Utility of Stability and Tear Location in a Classification System for Discoid Meniscus Surgical Planning
Authors: Yang Brian , Logan Catherine A. , Feroe Aliya G. , Kocher Sophia D. , Williams Kathryn A. , Kocher Mininder S. 
Published: September 2021

Background:
Despite the presence of multiple classification systems for discoid meniscus, no system has yet to demonstrate utility in predicting the need for meniscal repair. The purpose of this study was to correlate characteristics associated with meniscal repair and propose a model that can inform preoperative planning and initial counseling of surgical plans and expectations.

Methods:
Medical and operative records of 434 knees with lateral discoid meniscus in children and adolescents treated between 1991 and 2016 were reviewed retrospectively to determine the surgical procedure performed (saucerization with or without meniscal repair), discoid meniscal morphology and stability, and location and type of any associated tear. Univariate associations between discoid meniscal characteristics and surgery type were calculated and a logistic regression model of surgery type was generated.

Results:
In univariate models, unstable menisci (93%, or 179/204, P<0.001) and menisci with tears extending peripherally (75%, or 85/204, P<0.001) were more likely to receive surgery with repair. In isolation, instability demonstrated 89% sensitivity and 94% specificity in predicting surgery with repair. A logistic regression model including stability, tear, and their interaction (stability×tear) showed that that the odds of unstable lateral discoid menisci receiving surgery with repair was 114 times higher than stable menisci (P<0.001) while lateral discoid menisci with peripherally extending tears had 6.4 times higher odds of receiving repair than those that had an isolated central tear (P<0.001).

Conclusion:
Stability and tear location of lateral discoid menisci were associated with surgical treatment in univariate and logistic regression models. The proposed classification system, in which menisci are classified by stability [Stable (S0), Unstable (S1), morphology (Incomplete (M0), Complete (M1))], and tear [No tear (T0), Central tear, isolated (T1), or Central tear, peripheral extension (T2)], is easily remembered and predicts surgical repair for discoid menisci. This scheme can serve to inform preoperative planning and initial counseling of primary surgical management and postoperative expectations. Subsequent research should develop a system that predicts meniscal survival and patient outcomes following the index operation.

Level of Evidence:
Level III.
Crash Performance of Rear-facing Restraints With a Fracture Type Spica Casted 1-Year-Old Dummy
Authors: Collins Angela , McKean Lucas , Ostrander James , Nagarajan Sundar , Atkinson Patrick , Atkinson Theresa 
Published: September 2021

Background:
Motor vehicle crashes represent a significant cause of mortality and morbidity for young children. Safely restraining a child is typically more complicated for special cases such as children treated with a hip spica cast. In the current study, hip spica casts typical for treatment of a femoral fracture were applied to a crash dummy representing the size and weight of a 1-year-old child. This spica casted dummy was used to study the performance of 4 rear-facing car seats in a series of simulated frontal impacts.

Methods:
The restrained, rear-facing dummy was subjected to a frontal crash test at 30 mph (48 kph) per federal guidelines. Two of the tested car seats were specifically designed for transporting children with hip spica casts, while the other 2 were conventional seats capable of accommodating the cast. All seats were installed per the manufacturer’s instructions. As a control, tests were performed without a cast using the conventional/standard seats.

Results:
The lowest overall loading of the dummy’s head, neck, and chest occurred during tests with the standard seats. While it was easier to seat the casted child in the spica-specific seats, these designs led to greater loading on the dummy’s body. In a spica-specific seat, the chest acceleration values exceeded the federal limit in a test where the seat was installed in a reclined orientation that was within the manufacturer’s described positioning.

Conclusions:
Spica-specific seats more easily accommodate the cast, but conventional seats can provide similar levels of protection in a crash. As cast and seat designs continue to evolve, hospitals might consider having a range of seats available for patient use. It is important to help caregivers make informed decisions on how and when to transport children with hip spica casts.
Iron deficiency and early childhood caries: a systematic review and meta-analysis
Authors: Ji Shuai-Qi , Han Rui , Huang Ping-Ping , Wang Shuang-Yi , Lin Hao , Ma Lei 
Published: September 2021

Abstract

Backgrounds:
Previous surveys have found that children with iron deficiency (ID) were likely to suffer from early childhood caries (ECC). We aimed to assess the scientific evidence about whether ID is intrinsically related to ECC.

Methods:
The medical subject headings (MeSH) terms and free words were searched on PubMed, Web of Science, Cochrane, China National Knowledge Infrastructure, Wanfang, and the Database for Chinese Technical Periodicals from March 2020 to September 2020. Two researchers independently screened the articles. Data extraction and cross-checking were performed for the studies that met the inclusion criteria. Meta-analysis was performed using the Cochrane Collaboration's Review Manager 5.3 software.

Results:
After excluding duplication and irrelevant literature, 12 case-control studies were included in the study. The meta-analysis demonstrated that children with ECC were more likely to have ID (odds ratio [OR] = 2.63, 95% confidence interval [CI]: [1.85, 3.73], P < 0.001). There was no statistically significant association found between the level of serum ferritin and ECC (weighted mean difference (WMD) = −5.80, 95% CI: [−11.97, 0.37], P = 0.07). Children with ECC were more likely to have iron-deficiency anemia (OR = 2.74, 95% CI: [2.41,3.11], P < 0.001). The hemoglobin (HGB) levels in the ECC group were significantly lower compared with that in the ECC-free group (WMD = −9.96, 95% CI: [−15.45, −4.46], P = 0.0004). The mean corpuscular volume (MCV) levels in the ECC group were significantly lower compared with that in the ECC-free group (WMD = −3.72, 95% CI: [−6.65, −0.79], P = 0.01).

Conclusions:
ID was more prevalent in children with ECC, and the markers of iron status in the ECC group, such as serum ferritin, HGB, and MCV, were relatively lower than the ECC-free group.
