Introduction The middle fossa craniotomy (MFCs) is commonly utilized for spontaneous cerebrospinal fluid (CSF) leaks, encephaloceles, and superior semicircular canal dehiscence (SSCD). This study compares postoperative outcomes of MFCs with and without LD use. Methods A retrospective cohort study of adults over the age of 18 years presenting for the repair of nonneoplastic CSF leak, encephalocele, or SSCD via MFC from 2009 to 2021 was conducted. The main exposure of interest was the placement of an LD. The primary outcome was the presence of postoperative complications (acute/delayed neurologic deficit, meningitis, intracranial hemorrhage, and stroke). Secondary outcomes included operating room (OR) time, length of stay, recurrence, and need for reoperation. Results In total, 172 patients were included, 96 of whom received an LD and 76 who did not. Patients not receiving an LD were more likely to receive intraoperative mannitol (n = 24, 31.6% vs. n = 16, 16.7%, p = 0.02). On univariate logistic regression, LD placement did not influence overall postoperative complications (OR: 0.38, 95% confidence interval [CI]: 0.05–2.02, p = 0.28), CSF leak recurrence (OR: 0.75, 95% CI: 0.25–2.29, p = 0.61), or need for reoperation (OR: 1.47, 95% CI: 0.48–4.96, p = 0.51). While OR time was shorter for patients not receiving LD (349 ± 71 vs. 372 ± 85 minutes), this difference was not statistically significant (p = 0.07). Conclusion No difference in postoperative outcomes was observed in patients who had an intraoperative LD placed compared to those without LD. Operative times were increased in the LD cohort, but this difference was not statistically significant. Given the similar outcomes, we conclude that LD is not necessary to facilitate safe MCF for nonneoplastic skull base pathologies. [ABSTRACT FROM AUTHOR]

Sport-related concussion (SRC) is an evolving public health concern among youth athletes. Despite emerging evidence that race and ethnicity are important factors in determining concussion outcomes, studies examining race and ethnicity are limited. We conducted a systematic review to (1) determine the prevalence of SRC studies in which participants' race or ethnicity is reported, (2) describe how race and ethnicity are used within each study, and (3) assess predictive factors for the reporting of race and ethnicity. PubMed, Embase, PsycINFO, and CINAHL databases. Study inclusion criteria were (1) primary and peer-reviewed research; (2) related to the diagnosis, treatment, or recovery of SRC; (3) involving school-aged athletes (ages 5 to 25); and (4) with 25 or more participants. The search was performed in March 2021 and included only studies published after March 2013. For each article, we looked at whether race and ethnicity were reported, and if so, which races or ethnicities were mentioned. For each race or ethnicity mentioned, we extracted the corresponding sample size and how they were used as variables in the study. Of 4583 studies screened, 854 articles met inclusion criteria. Of the included articles, 132 (15.5%) reported race, and 65 (7.6%) reported ethnicity, whereas 721 (84.4%) reported neither. When examining the demographic characteristics of the 132 studies that reported race, 69.8% of athletes were White. Additionally, 79.5% of these studies used race solely as a demographic descriptor as opposed to a main exposure or covariate of interest. Studies published more recently were more likely to report race. Further, studies in specific study or journal topics and specific geographic locations of the authors were more likely to report race. Reporting of race and ethnicity is limited in current SRC literature. Future authors should improve the reporting of race and ethnicity, diversify study samples by focusing on enrolling athletes from underrepresented groups, and consider the potential effect of race and ethnicity as social determinants of health on risk factors, recovery, and long-term sequelae after SRC.

Repeat sport-related concussion (SRC) is anecdotally associated with prolonged recovery. Few studies have examined repeat concussion within the same athlete. We sought to explore differences in symptom burden and recovery outcomes in an individual athlete's initial and repeat SRC. A retrospective within-subject cohort study of athletes aged 12–23 years diagnosed with two separate SRCs from 11/2017–10/2020 was conducted. Primary outcomes were initial symptom severity and time-to-symptom-resolution. Secondary outcomes included return-to-learn (RTL) and return-to-play (RTP) duration. Of 868 athletes seen, 47 athletes presented with repeat concussions. Median time between concussions was 244 days (IQR 136–395). Comparing initial to repeat concussion, no differences were observed in time-to-clinic (4.3 ± 7.3vs.3.7 ± 4.6 days, p = 0.56) or initial PCSS (26.2 ± 25.3 vs. 30.5 ± 24.1, p = 0.32). While a difference was observed in time-to-symptom resolution between initial/repeat concussion (21.2 ± 16.3 vs. 41.7 ± 86.0 days, p = 0.30), this did not reach statistical significance. No significant differences were observed in time-to-RTL (17.8 ± 60.6 vs. 6.0 ± 8.3 days, p = 0.26) and RTP (33.2 ± 44.1 vs. 29.4 ± 39.1 days, p = 0.75). Repeat concussion was not associated with symptom resolution on univariate (HR 1.64, 95% CI 0.96–2.78, p = 0.07) and multivariable (HR 0.85, 95% CI 0.49–1.46, p = 0.55) Cox regression. No significant differences in symptom duration and RTP/RTL were seen between initial/repeat concussion. [ABSTRACT FROM AUTHOR]

Care-seeking behaviors for sport-related concussion (SRC) are not consistent across demographic subgroups. Not only may these differences stem from health inequities, but they can perpetuate disparities in care for SRCs. To determine whether racial differences existed in the care pathway from injury to SRC clinic of adolescent athletes. Retrospective cohort study. Regional SRC center. Of 582 total athletes, 96 (16.5%) Black and 486 (83.5%) White adolescent athletes were diagnosed with SRC and evaluated within 3 months at the SRC clinic. Race was the defined exposure, dichotomized as Black or White. The 4 primary outcomes were (1) location of the first health system contact, (2) time from injury to the first health system contact, (3) time to the in-person SRC clinic visit, and (4) whether the athlete established care (>1 visit), was released immediately to an athletic trainer, or was lost to follow-up. Black and White athletes mostly presented directly to the SRC clinic (61.5% versus 62.3%) at a median (interquartile range) of 3 (1–5) and 4 (1–8) days, respectively (P =.821). Similar proportions of Black and White athletes also first presented to the emergency department (30.2% and 27.2%) at a median of 0 (0–1) versus 0 (0–1) days, respectively (P =.941). Black athletes more frequently had care transferred to their athletic trainer than White athletes (39.6% versus 29.6%) and less frequently established care (56.3% versus 64.0%), respectively; however, these differences were not statistically significant (P =.138). Loss to follow-up was uncommon among Black (4.2%) and White (6.4%) athletes alike. Within an established SRC referral network and multidisciplinary clinic, no racial disparities were observed in how athletes were initially managed or ultimately presented to the SRC clinic despite racial differences in school type and insurance coverage. The SRC center assimilation and affiliation with school systems may be helpful in improving access and providing equitable care across diverse patient demographics. [ABSTRACT FROM AUTHOR]
