The impact of the California state lockdown during the COVID-19 pandemic on management of patients with pancreatic ductal adenocarcinoma.

BACKGROUND AND OBJECTIVES: The SARS-COVID-19 pandemic significantly limited healthcare access. We sought to evaluate whether California's lockdown in March 2020 affected staging and time to treatment of pancreatic ductal adenocarcinoma (PDAC). We hypothesized that patients diagnosed after the lockdown would have longer time to treatment and higher stage at presentation. METHODS: We retrospectively identified and categorized 1294 patients presenting to five University of California healthcare systems with a new diagnosis of PDAC into "pre-lockdown" and "post-lockdown" groups based on timing of pathologic diagnosis. RESULTS: In the 12 months pre-lockdown, 835 patients were diagnosed with PDAC, and 459 patients in the 6 months post-lockdown. Demographics, staging, and treatment type were similar between eras. There was a decreased male:female ratio post- versus pre-lockdown (0.97 vs. 1.25; p = 0.03). Time from symptom onset to first treatment was significantly increased among females post-lockdown (p = 0.001). However, overall time from diagnosis to first treatment was shorter in the post-lockdown era (median 23 vs. 26 days, p < 0.001). CONCLUSIONS: The COVID-19 lockdown did not significantly delay initial presentation, diagnosis, or treatment of newly diagnosed PDAC patients. Time from diagnosis to first treatment was shorter post-lockdown. Reduced healthcare utilization for minor complaints and increased telehealth utilization may have contributed.

The impact of routine post-anesthesia care unit extubation for pediatric surgical patients on safety and operating room efficiency.

PURPOSE: Maximizing operating room (OR) efficiency is essential for hospital cost containment and effective patient throughput. Little data is available regarding the safety and efficacy of extubation of children in the post-anesthesia care unit (PACU) by a nurse rather than in the OR. We sought to evaluate the impact of a long-standing practice of PACU extubation upon airway complications and OR efficiency. METHODS: The records of 1930 children who underwent inguinal hernia repair, laparoscopic appendectomy or pyloromyotomy at a children's hospital between July, 2018 and June, 2020 were reviewed. Extubations were performed in the OR only when the PACU was inadequately staffed or during the early months of the Covid-19 pandemic. Cases in which there was a deep extubation, a PACU hold was in effect or a patient went directly to an inpatient unit from the OR were excluded. Intra- and post-operative time metrics were recorded and emergency airway interventions were assessed. RESULTS: 1747 operations were evaluated. Time from the end of the procedure to leaving the OR ranged from 4.1 to 4.8 min when extubation was done in the PACU and was 6-9 min less than with OR extubation. (see table). There were 23 airway events (1.5% of all cases) after PACU extubation that necessitated only brief bag-mask ventilation. There were no cases of re-intubation. CONCLUSIONS: In a large population of children undergoing diverse surgical procedures, post-anesthesia care unit extubation was safe and resulted in rapid transfer of patients from the operating room after completion of their operation. Time saved because of shorter operating room times reduces hospital costs and can allow for increased throughput. Extubation in the post-anesthesia care unit may not only be as safe as operating room extubation, but may result in fewer serious airway events as patients may be less likely to have their endotracheal tube removed prematurely. LEVEL OF EVIDENCE: Treatment Study, Level III.

An assessment of dexmedetomidine as an opioid-sparing agent after neonatal open thoracic and abdominal operations.

OBJECTIVE: To evaluate the efficacy of dexmedetomidine as an opioid-sparing agent in infants following open thoracic or abdominal operations. METHODS: Retrospective review of postoperative neonates who received IV acetaminophen with or without dexmedetomidine. The primary outcome was opioid dosage within the first ten postoperative days. Secondary outcomes included times to extubation, full feedings and discharge. RESULTS: 112 infants met inclusion criteria. Those managed with dexmedetomidine received 1.8-4.3 times more opioid on postoperative days 1-3, had longer times to extubation and trended towards longer lengths of hospital stay than infants who were not. Opioid was dosed >0.2 ME/kg on only 23% of days when the acetaminophen dose was >40 mg/kg/day and 10% of days when the acetaminophen dose was >45 mg/kg. CONCLUSION: Dexmedetomidine may not be opioid sparing after major operations in neonates and its use delays recovery. IV acetaminophen dosed at 40 mg/kg/day or greater may yield the most substantial opioid-sparing effect.

Masses of the Sternoclavicular Area: Case Series and Review of the Literature.

OBJECTIVE: Masses of the sternoclavicular area are rare, and are not well described in the literature. We aim to present a series of patients with masses in this location and to review all reported English language cases of sternoclavicular masses in pediatric patients. METHODS: This is a case series of pediatric patients with masses of the sternoclavicular area presenting to a tertiary care pediatric hospital from 2010 through 2017. Data was collected by using ICD-9 and ICD-10 codes to query the electronic medical record. Chart review included age at presentation, mass characteristics, medical and surgical interventions, and pathology results. A review of the literature was then performed. RESULTS: Ten patients with masses overlying the sternoclavicular area were identified. Four patients presented with abscess and were treated with incision and drainage. Three of these patients were then treated with staged excision once infection cleared. Two additional patients were treated with primary excision. Four patients were treated with observation. The most common histopathologic finding was epidermoid. One patient was found to have a dermoid cyst, and 1 had a congenital cartilaginous rest. CONCLUSION: Epidermoids and dermoids are the most common masses overlying the sternoclavicular area. Controversy remains regarding the embryologic origin of sternoclavicular masses. The differential for masses in this area also includes branchial remnants, bronchogenic cysts, ganglion cysts, or septic arthritis.

Disparity in Opportunities: Is It Harder to Match Into Plastic Surgery Residency Without a Home Plastic Surgery Division?

ABSTRACT: Medical students pursuing plastic surgery training must overcome multiple challenges to successfully match in such a highly coveted subspecialty. This adversity is amplified in applicants from medical schools without a home plastic surgery residency program and academic division. There is a paucity of data on the advantage of medical students applying from an institution with a home residency program. Applicant data from the past 5 years were accessed from the Association of American Medical Colleges Electronic Residency Application Services statistics form. Individual home programs of successfully matched applicants were collected from plastic surgery residency websites. A survey was distributed to 32 students pursuing specialty residencies from home medical schools without a plastic surgery residency. Evaluation of a subset of incoming plastic surgery interns revealed that 72% of matched applicants attended home medical institutions with plastic surgery residency programs. Seventy-seven percent of survey respondents felt strongly that students at institutions with home residency programs had a significant advantage. The current COVID pandemic is changing the landscape of subinternships and bringing to light the disadvantage students face without home residency programs. The development of virtual subinternships, online mentorship, and selection of students for subinternships from geographic areas without home programs may help address some disparities in educational opportunities. Continuing these virtual programs and offering preferential help to disadvantaged medical students permanently is an avenue for the field of plastic surgery to be a leader in diversity and inclusion.

Influence of Pediatric Endoscopic Endonasal Skull Base Resections on Midface and Skull Base Development.

OBJECTIVE: The purpose of this study is to use imaging data to determine if endoscopic endonasal surgery (EES) for skull base tumor resection interrupts skull base growth and development, resulting in an atrophic midface skeletal structure, compared to matched normal controls. METHODS: Data were collected by a retrospective chart review done on children aged 16 years and below who underwent endoscopic tumor resection and had pre- and postoperative magnetic resonance imaging with relevant midface anatomy. 121 normal controls were matched to 20 EES patients by age and gender. Three measurements related to midface anatomy were taken from 1 sagittal T1 slice and 1 axial T2 slice of each scan. Statistical analysis was used to compare growth measures between cases and controls. RESULTS: Twenty patients who underwent EES between November 2015 and April 2018 met our inclusion criteria. The mean age of the patients, 11 males and 9 females, was 10 years, and 8 patients (38%) were aged 7 years or younger. Six patients who had a high-flow CSF leak obtained a nasoseptal flap. A student T test and multivariate regression analysis found that EES did not affect midface and skull base growth. Among the variables assessed, age appears to be the only driver of growth. CONCLUSION: There were no identified differences in craniofacial growth in pediatric patients undergoing EES for skull base tumor resection as compared to the control group. EES does not appear to significantly interfere with midface/skull base development and is a good surgical option for pediatric patients.

Electric scooter craniofacial trauma.

OBJECTIVE: The use of standing electronic scooters associated with micromobility applications (e-scooters) has risen nationally. The aim of this study was to obtain a detailed view of soft tissue and bony craniofacial injury associated with e-scooter-related trauma. METHODS: Single-institution retrospective case series of patients presenting to a level 1 trauma center emergency department or trauma unit with documented e-scooter-related craniofacial injury. RESULTS: Of 203 included patients, 188 (92.6%) patients sustained craniofacial injury. One hundred thirty-one (64.5%) had exclusively soft tissue injury, 3 (1.5%) exclusively bony injury, 51 (25.1%) both soft and bony injuries, and twenty-five (12.3%) patients sustained dental injury. Aesthetic units most frequently sustaining acute soft tissue injury were the forehead (n = 106, 34.6%), scalp (n = 36, 11.8%), chin (n = 34, 11.1%), upper lip (n = 32, 10.5%), and cheek (n = 31, 10.1%). Aesthetic subunits most often sustaining acute soft tissue injury included the brow (42, 13.7%), central forehead (39, 12.7%), lateral forehead (n = 25, 8.2%), and upper lip vermillion (n = 23, 7.5%). Craniofacial osseous fracture most often occurred in the orbit (n = 42, 24.6%) and maxilla (n = 40, 23.4%). Individual osseous segments most frequently sustaining acute fracture included the anterior maxillary sinus wall (n = 22, 12.9%), nasal bone (n = 20, 11.7%), lateral orbital wall (n = 16, 9.4%), orbital floor (n = 15, 8.8%), and zygomatic bone (13, 7.6%). CONCLUSIONS: Our analysis demonstrates that most patients presenting to our center with craniofacial trauma sustained acute bony fracture, most often to the midface. Our data of common injuries associated with e-scooter trauma could inform implementation in the form of facial safety equipment or safety skills training for e-scooter riders. LEVEL OF EVIDENCE: 4.

Approaching the Sella through the Nonpneumatized Sphenoid in Pediatric Patients.

Objective The purpose of this study is to specifically assess pediatric patients with nonpneumatized sphenoid sinuses who have undergone transsphenoidal resections of skull base tumors and assess the complications and outcomes. Methods Data was collected by a retrospective chart review done on children ages 7 and under who underwent endoscopic tumor resection and had a partially or completely nonpneumatized sphenoid sinus on preoperative computed tomography imaging. Surgical data collected included surgical corridor, gross total versus subtotal resection, repair method, use of septal flap, intraoperative and postoperative cerebrospinal fluid leak, and estimated blood loss. Results Six patients were identified that fit our inclusion criteria who underwent surgery between November 2015 and April 2018 (3 males, 3 females; average age = 4.28 years). Tumor pathologies include three craniopharyngiomas, Rathke cleft cyst, meningocele, and neuroblastoma. All cases involved varying percentages of sphenoid sinus pneumatization. All cases except one craniopharyngioma and the neuroblastoma required removal of cancellous bone to access pathology. Degree of sphenoid pneumatization tended to be greater with age and resulted in less intraoperative bleeding. The two youngest patients with completely nonpneumatized sphenoid sinuses lost 61.73 and 17.52% of their total blood volume intraoperatively. Procedures were able to be adequately performed and pathology completely addressed with minimal postoperative complications and no postoperative CSF leaks. Conclusions Intraoperative challenges including hemorrhage are likely in nonpneumatized patients, and thus surgeons should be prepared with adequate vascular access and blood products. Hemorrhage and total blood volume loss are increased in the younger patients with no sphenoid pneumatization. Despite the additional challenges, a nonpneumatized sphenoid sinus is not a contraindication for an endoscopic resection in the pediatric population.

A Comparison of Intracranial Volume Growth in Normal Children and Patients With Metopic Craniosynostosis.

BACKGROUND: The impact of metopic craniosynostosis on intracranial volume (ICV) and ICV growth is unclear. In addition, the relationship between head circumference (HC) and ICV in these patients is not previously described. METHODS: A retrospective review of 72 patients with metopic craniosynostosis was performed. The ICVs were calculated from manually segmented preoperative computed tomography scans. Magnetic resonance imaging data for 270 healthy children were available. The ICVs were calculated in FreeSurfer.First, a growth curve for metopic patients was generated and a logarithmic best-fit curve was calculated. Second, the impact of metopic craniosynostosis on ICV relative to healthy controls was assessed using multivariate linear regression. Third, the growth curves for metopic patients and healthy children were compared.Pearson's correlation was used to measure the association between HC and ICV. RESULTS: Mean metopic ICV was significantly lower than normal ICV within the first 3 to 6 months (674.9 versus 813.2 cm; P = 0.002), 6 to 9 months (646.6 versus 903.9 cm; P = 0.005), and 9 to 12 months of life (848.0 versus 956.6 cm; P = 0.038). There was no difference in ICV after 12 months of age (P = 0.916).The ICV growth in patients with metopic craniosynostosis is defined by a significantly different growth curve than in normal children (P = 0.005).The ICV and HC were highly correlated across a broad range of ICVs and patient age (r = 0.98, P < 0.001). CONCLUSION: Patients with metopic craniosynostosis have significantly reduced ICVs compared to healthy children, yet greater than normal ICV growth, which allows them to achieve normal volumes by 1 year of age. The HC is a reliable metric for ICV in these patients.

Diversity in Plastic Surgery: Trends in Minority Representation among Applicants and Residents.

BACKGROUND: Prior studies have shown a lack of diversity among plastic surgery trainees. The authors evaluate trends in minority representation among applicants to plastic surgery and the correlation with practicing residents, compared to other specialties. METHODS: The Association of American Medical Colleges Electronic Residency Application Service provided applicant data for integrated, independent plastic surgery, and other select specialties from 2010 to 2016. Journal of the American Medical Association Graduate Medical Education annual reports and Association of American Medical Colleges graduate student questionnaires provided resident and medical student data. Binomial distribution analysis was used to assess differences in Black, Hispanic, and female proportions of applicants and residents. Best-fit trend lines were compared among groups and specialties. RESULTS: Women have seen an increase in integrated and independent resident representation (+2.23 percent and +0.7 percent per year, respectively) over the past 7 years, despite a relative decrease in applicants. The proportion of female applicants and residents correlated yearly for all specialties (p > 0.05). Conversely, for all years and all specialties, the Black proportion of applicants was significantly higher than the resident representation of the same year (p < 0.05). Hispanic applicant and resident representation have seen a minimal change. CONCLUSIONS: Female representation among trainees has increased greatly, but there has been a decline in Black representation of integrated plastic surgery residents despite increases in medical school graduates and applicants. The data highlight a discrepancy between the population of applicants and residents suggesting that barriers starting from medical school may contribute to the lack of diversity in plastic surgery.
