Cerebrovascular Complications Associated With Iatrogenic Fungal Meningitis Following Surgical Procedures in Mexico.

BACKGROUND: The current fungal meningitis outbreak caused by contaminated epidural anesthesia with Fusarium solani among patients who underwent surgical procedures in Matamoros, Mexico remains a cause of concern. Its association with an increased susceptibility for cerebrovascular complications (CVC) has not been reported. This single-center study describes 3 patients with a unique pattern of CVC attributed to fungal meningitis. METHODS: A retrospective case series of patients diagnosed with fungal meningitis following surgical procedures under contaminated epidural anesthesia who developed a unique pattern of CVC during their hospitalization. RESULTS: Three female patients (mean age, 35 years) with CVC due to iatrogenic fungal meningitis were included. Positive Fungitell ß-D-glucan assay in cerebrospinal fluid was documented in all cases, and F. solani was confirmed by polymerase chain reaction in case 3. All cases were complicated by severe vertebrobasilar circulation vasculopathy and arterial dissections with resultant subarachnoid hemorrhage and intraventricular hemorrhage, ultimately leading to patients' death. CONCLUSIONS: The death toll from the ongoing fungal meningitis outbreak keeps rising, underscoring the need for early recognition and aggressive treatment. We highlight the risk for vertebrobasilar circulation CVC among these patients. The angioinvasive nature of F. solani is yet to be clarified; however, a clear pattern has been observed. Public health awareness should be raised and a strong response should be pursued.

Association of Rideshare Use With Alcohol-Associated Motor Vehicle Crash Trauma.

Importance: Motor vehicle crashes (MVCs) are an important public health concern. Recent trends suggest that introducing rideshare services has decreased the incidence of MVCs. However, detailed analyses linking rideshare volume, convictions for impaired driving, and nonfatal MVC traumas remain inconclusive. Objective: To determine if there is an association between rideshare use and MVC traumas and convictions for impaired driving in Houston, Texas. Design, Setting, and Participants: This multicenter cohort study was conducted between January 2007 and November 2019 with hospital data from the Red Duke Trauma Institute within the Memorial Hermann Hospital-Texas Medical Center and Ben Taub General Hospital. Rideshare data from Uber and Google covered trips taken within Houston, Texas, from February 2014 (the date of deployment of Uber to Houston) to December 2018. Impaired driving convictions included all indictments made by the Harris County, Texas, District Attorney's office from January 2007 to December 2018. All adults with MVC traumas evaluated at both centers in the study population (individuals >16 years with a mechanism of injury classified under "motor vehicle collision") were included. Impaired driving incidents were included only if the final legal outcome was conviction. Main Outcomes and Measures: The primary study outcomes were the incident rate ratios for hourly MVC traumas and daily impaired driving convictions. Results: A total of 23 491 MVC traumas (involving patients with a mean [SD] age of 37.9 [17.8] years and 14 603 male individuals [62.1%]), 93 742 impaired driving convictions, and more than 24 million Uber rides were analyzed. Following the introduction of Uber in February 2014, MVC traumas decreased by 23.8% (from a mean [SD] of 0.26 [0.04] to 0.21 [0.06] trauma incidents per hour) during peak trauma periods (Friday and Saturday nights). The incident rate ratio of MVC traumas following Uber deployment was 0.33 (95% CI, 0.17-0.67) per 1000 indexed rides (P = .002). Furthermore, rideshare use was associated with a significant, geographically linked reduction in impaired driving convictions between January 2014 to December 2019 (incidence rate ratio, 0.76 [95% CI, 0.73-0.78]; P < .001). Conclusions and Relevance: In this study, introducing rideshare services in the Houston metropolitan area was associated with significant reductions in MVC traumas and impaired driving convictions. Increased use of rideshares may be an effective means of reducing impaired driving and decreasing rate of MVC traumas.

Factors Associated With Pregnancy and Perinatal Outcomes in Female Neurosurgeons: A Cross-Sectional Study.

Neurosurgery is male dominated with women representing only 12% of residents and 5% of practicing neurosurgeons. The conflicting demands of training versus pregnancy and motherhood are significant deterrents to women entering the field. We examined pregnancy incidence and timing, perinatal complications, and the perceived career impact of motherhood on female neurosurgeons using an anonymous survey of 643 training, practicing, and retired female neurosurgeons from the United States. Among 260 respondents, 50.8% (132/260) reported pregnancies, with an average age at first pregnancy that was significantly higher than the national average (32.1 vs 26.3 yr). In all, 40.1% (53/132) of respondents reported perinatal complications in at least one of their pregnancies. Only 25% (33/132) of respondents noted designated program maternity allowances. The most significant challenges associated with being a mother and neurosurgeon reported were issues relating to work/life balance, "mommy guilt," and sleep deprivation. A majority of respondents, 70.1% (82/116), reported fear of backlash from co-residents, partners, and staff, as well as hindered career advancement related to childbearing. Female neurosurgeons face challenges surrounding family planning different from those faced by male practitioners. Higher perinatal and fetal complications, backlash from colleagues, and demanding workload are significant issues. Progress requires institutional support and mentorship for women to create a more diverse field of practitioners.

Outcomes and prognostic factors of pediatric patients with a Glasgow Coma Score of 3 after blunt head trauma.

PURPOSE: This study aims to assess outcomes of pediatric patients with blunt traumatic brain injury (TBI) with a presenting Glasgow Coma Score (GCS) of 3. METHODS: After local institutional review board approval, we identified patients ages 0 to15 years with blunt TBI and a reported GCS of 3 between 2007 and 2017 from a pediatric level 1 trauma center prospective registry. Exclusion criteria were cardiac death on arrival and penetrating injury. We recorded clinical variables from patients with a non-pharmacologic GCS of 3 and pupillary exam documented by a neurosurgical attending or resident. The original Glasgow Outcome Scale (GOS) was used to compare with other studies. Importance of variables to survival was calculated. RESULTS: A total of 88 patients (mean age 6.9 years) were included with a mortality rate of 68%. Twelve percent had a poor long-term outcome (GOS 2 or 3) while 20% had a good long-term outcome (GOS 4 or 5). Median follow-up was 1.8 years. Initial group comparison revealed patients in group 1 (survivors) had less hypotension on arrival (14% SBP < 90 mmHg vs. 66%, p < 0.0001), higher temperatures on arrival (36.3 °C vs 34.9 °C, p = 0.0002), lower ISS (29.7 vs 39.5, p = 0.003), less serious injury to other major organs (34% vs 61%, p = 0.02), more epidural hematomas (24% vs 7%, p = 0.04), and less evidence of brain ischemia on CT (7% vs 39%, p = 0.002) or brainstem infarct, hemorrhage, or herniation (0% vs 27%, p = 0.002). Differences between the 2 groups in age, sex, race, MOI, AIS score, presence of midline shift > 5 mm, or time from injury to hospital arrival or time to surgery were not statistically significant. Classification tree analysis showed that the most important variable for survival was pupillary exam; mortality was 92% in presence of bilateral, fixed dilated pupils. The relative importance of initial temperature, MOI, and hypotension to survivability was 0.79, 0.75, and 0.47, respectively. CONCLUSION: Twenty percent of our pediatric non-pharmacologic GCS 3 cohort had a good functional outcome. Lack of bilaterally fixed and dilated pupils was the most important factor for survival. Temperature, MOI, and hypotension also correlated with survival. The data support selective aggressive management for these patients.

Management of Venous Sinus-Related Epidural Hematomas.

BACKGROUND: Epidural hematomas (EDHs) involving the venous sinuses are uncommon and carry the risk of hemorrhage or venous infarction. We report the largest case series for superior sagittal sinus- and transverse sinus-related EDHs including surgical and nonsurgical management. We compare our findings to the relevant literature. METHODS: A retrospective review of the EDH cases at our center was performed from 2013-2018. Patients were analyzed by surgical versus conservative management, outcomes, and complications. RESULTS: Of the 268 EDH patients identified, 32 involved the venous sinuses (23 supratentorial and 9 infratentorial). Ten of the patients had surgery, and 22 were managed conservatively. No surgical complications occurred, and all had a Glasgow Outcome Scale score of 5 at follow-up. All of the nonsurgical patients had a Glasgow Outcome Scale score of 4 or 5 at follow-up except for 1 patient with prior disability. The literature search resulted in 39 infratentorial and 47 supratentorial EDHs involving venous sinuses. CONCLUSIONS: Surgical and nonsurgical management of EDHs involving the venous sinuses are both viable options with good outcomes. Surgical intervention is based on location, size, neurologic examination, expansion on serial imaging, and vascular imaging findings. Surgery has the potential for significant complications, but all surgical patients in our series had good outcomes at follow-up. Similarly, nonsurgically managed patients had good outcomes and our overall series demonstrates better outcomes with fewer complications than other similar series in the literature.
