Monitoring Intrafraction Motion of the Prostate During Radiation Therapy: Suggested Practice Points From a Focused Review.

PURPOSE: External beam radiation therapy to the prostate is typically delivered after verification of prostatic position with image guidance. Prostate motion can occur during the delivery of each radiation treatment between the time of localization imaging and completion of treatment. The objective of this work is to review the literature on intrafraction motion (IFM) of the prostate during radiation therapy and offer clinical recommendations on management. METHODS AND MATERIALS: A comprehensive literature review was conducted on prostate motion during prostate cancer radiation therapy. Information was organized around 3 key clinical questions, followed by an evidence-based recommendation. RESULTS: IFM of the prostate during radiation therapy is typically ≤3 mm and is unlikely to compromise prostate dosimetry to a clinically meaningful degree for men treated in a relatively short treatment duration with planning target volume (PTV) margins of ≥3 to 5 mm. IFM of 5 mm or more has been observed in up to ∼10% of treatment fractions, with limited dosimetric effect related to the infrequency of occurrence and longer fractionation of therapy. IFM can be monitored in continuous or discontinuous fashion with a variety of imaging platforms. Correction of IFM may have the greatest value when tighter PTV margins are desired (such as with stereotactic body radiation therapy or intraprostatic nodule boosting), ultrahypofractionated courses, or when treatment time exceeds several minutes. CONCLUSIONS: This focused review summarizes literature and provides practical recommendations regarding IFM in the treatment of prostate cancer with external beam radiation therapy.

Management of pediatric appendicitis during the COVID-19 pandemic: A nationwide multicenter cohort study.

BACKGROUND: The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes. METHODS: A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed. RESULTS: Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p < 0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p < 0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6). CONCLUSION: Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

Between a Rock and a Hard Place: Anticoagulating an Adolescent with Post-Tonsillectomy Massive PE: A Case Report.

OBJECTIVES: To report a case of a morbidly obese 17-year-old boy who presented 4 days post-tonsillectomy with acute deep venous thromboses and a massive pulmonary embolism. To describe a protocol and decision-making tree for providing anticoagulation in the immediate post-tonsillectomy period. METHODS: A chart review and review of the literature. RESULTS: The patient ultimately did well and had no bleeding from the tonsil beds or further thromboembolic complications. A review of the literature revealed no available data regarding the safety of anticoagulation in the immediate post-tonsillectomy period. CONCLUSIONS: We propose that if anticoagulation is needed within 14 days of tonsillectomy, submaximal anticoagulation with a reversible and titratable anticoagulant may be optimal. A multidisciplinary team approach is needed for these complex cases. Future reporting and investigation of anticoagulation post-tonsillectomy is needed.

Rural Otolaryngology Care Disparities: A Scoping Review.

OBJECTIVE: To broadly synthesize the literature regarding rural health disparities in otolaryngology, categorize findings, and identify research gaps to stimulate future work. STUDY DESIGN: Scoping review. DATA SOURCES: A comprehensive literature search was performed in the following databases: PubMed/MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Google Scholar, and CINAHL. REVIEW METHODS: The methods were developed in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Peer-reviewed, English-language, US-based studies examining a rural disparity in otolaryngology-related disease incidence, prevalence, diagnosis, treatment, or outcome were included. Descriptive studies, commentaries, reviews, and letters to the editor were excluded. Studies published prior to 1980 were excluded. RESULTS: The literature search resulted in 1536 unique abstracts and yielded 79 studies that met final criteria for inclusion. Seventy-five percent were published after 2010. The distribution of literature was as follows: otology (34.2%), head and neck cancer (20.3%), endocrine surgery (13.9%), rhinology and allergy (8.9%), trauma (5.1%), laryngology (3.8%), other pediatrics (2.5%), and adult sleep (1.3%). Studies on otolaryngology health care systems also accounted for 10.1%. The most common topics studied were practice patterns (41%) and epidemiology (27%), while the Southeast (47%) was the most common US region represented, and database study (42%) was the most common study design. CONCLUSION: Overall, there was low-quality evidence with large gaps in the literature in all subspecialties, most notably facial plastic surgery, laryngology, adult sleep, and pediatrics. Importantly, there were few studies on intervention and zero studies on resident exposure to rural populations, which will be critical to making rural otolaryngology care more equitable in the future.

Gender Differences in Program Factors Important to Applicants When Evaluating Orthopaedic Surgery Residency Programs.

BACKGROUND: Despite specialty-driven efforts to improve diversity in the field, few women apply to orthopaedic residency, and women are unevenly distributed among programs. There is little evidence-based information on factors that may attract female applicants. OBJECTIVE: This study aims to identify factors important to applicants when evaluating orthopaedic residency programs and to identify gender-specific differences. METHODS: All applicants to a single orthopaedic surgery residency program in the 2017 Match were asked to fill out an anonymous survey. Respondents rated the importance of 35 factors when evaluating orthopaedic residency programs. The percentage of highly rated factors was calculated. Statistical analysis was performed for each factor to assess differences by gender. RESULTS: Of 1013 applicants who applied to orthopaedic surgery residency in 2017, 815 (80%) applied to our program, and 218 (27%) completed the survey. The most important factors when evaluating a residency program for both genders were (1) perceptions of current residents; (2) interactions with members of the program; (3) program reputation and fellowship placement; (4) geographic location; and (5) impressions after rotation at a program. Female applicants rated the presence of female and minority residents and faculty and program reputation for gender and racial/ethnic diversity higher than male applicants. CONCLUSIONS: When choosing an orthopaedic surgery residency program, women more often reported the presence of female residents and faculty, program reputation for gender diversity, reputation for racial/ethnic diversity, presence of minority residents and faculty, and their personal interactions with members of the program as important factors.
