Relationship between otolaryngology interest groups and residency match results.

BACKGROUND: Many students have limited exposure to otolaryngology-head and neck surgery (OTOHNS) throughout medical school, limiting recruitment of medical students early in their medical careers. OBJECTIVE: To assess the association between otolaryngology interest groups (OIGs) at medical schools and percentage of students matching into OTOHNS residency programs. To characterize specific aspects of OIGs that may impact the percentage of students matching into OTOHNS residency programs from a given medical school. METHODS: Data was obtained from web searches of 141 accredited U.S. allopathic medical schools to see if they possessed OIGs. Information on the various activities and opportunities that OIGs participated in was collected through medical school websites. 2020 NRMP® match results data were obtained. RESULTS: Web searches found that 73 % (103 out of 141) of U.S. allopathic medical schools have OIGs. Medical schools with OIGs were associated with a 35 % increase in the median percentage of OTOHNS matches (P = 0.022). Of the 103 medical schools with OIGs, 53 % (55) of the schools had information on their websites describing activities and opportunities that their OIGs participate in. OIGs with research and/or mentorship opportunities were associated with increases in OTOHNS matches by 32 % (P = 0.043) and 83 % (P = 0.012), respectively. CONCLUSION: The presence of an OIG at a medical school is associated with an increased percentage of students matching into OTOHNS from that medical school. OIGs that provide research or mentorship opportunities are associated with an increased percentage of students matching into OTOHNS from those medical schools.

A Retrospective Genomic Landscape of 661 Young Adult Glioblastomas Diagnosed Using 2016 WHO Guidelines for Central Nervous System Tumors.

The authors present a cohort of 661 young adult glioblastomas diagnosed using 2016 WHO World Health Organization Classification of Tumors of the Central Nervous System, utilizing comprehensive genomic profiling (CGP) to explore their genomic landscape and assess their relationship to currently defined disease entities. This analysis explored variants with evidence of pathogenic function, common copy number variants (CNVs), and several novel fusion events not described in literature. Tumor mutational burden (TMB) mutational signatures, anatomic location, and tumor recurrence are further explored. Using data collected from CGP, unsupervised machine-learning techniques were leveraged to identify 10 genomic classes in previously assigned young adult glioblastomas. The authors relate these molecular classes to current World Health Organization guidelines and reference current literature to give therapeutic and prognostic descriptions where possible.

Advances in the Use of Hypoglossal Nerve Stimulator in Adolescents With Down Syndrome and Persistent Obstructive Sleep Apnea-A Systematic Review.

INTRODUCTION: The Hypoglossal Nerve Stimulator (HNS) is a novel therapy that has been extensively studied in adults and more recently, it has been incorporated in children with Down Syndrome (DS) with persistent obstructive sleep apnea after adenotonsillectomy and trial of continuous positive airway pressure treatment. This systematic review article aims to examine the existing literature on HNS use in children to explore the benefits, efficacy, and parental experiences. METHODS: MEDLINE, Web of Science and EMBASE were searched to include all studies published up to March 2nd, 2023, on the topic of HNS use in pediatric population under 21 years old. RESULTS: A total of 179 studies were initially identified from which 10 articles were consistent with the inclusion criteria. Nine articles addressed outcomes after implantation of the HNS device in children with DS and 1 article explored the parental experiences. Findings were similar across studies where after implantation of HNS, there was marked improvement in polysomnographic outcomes and quality of life scores with high level of compliance. CONCLUSIONS: HNS holds promise as an effective treatment option for pediatric patients with DS and persistent OSA after AT and CPAP trials. It significantly improves sleep-disordered breathing, quality of life, and neurocognitive measures, leading to substantial and sustained benefits for these children. While the findings are encouraging, further research is needed to explore the potential of HNS in other pediatric populations without DS and to raise awareness among healthcare providers about this treatment option. Overall, HNS may offer significant long-term benefits for the overall well-being and health of pediatric patients with DS and persistent OSA.

Internet and social media research by parents of pediatric otolaryngologic patients.

PURPOSE: Public access to medical information has increased dramatically with the growth and accessibility of the Internet. The goal of this study is to characterize how parents use the Internet to understand and make decisions about their child's otolaryngologic surgery. MATERIALS AND METHODS: A survey was distributed to parents of pediatric patients undergoing otolaryngologic procedures to assess if and how parents gather information about their child's surgery. RESULTS: 105 parents completed the survey. 59.4% of parents gathered online information about their child's surgery. 86% of these parents used Google, 36% used YouTube, 16% used Wikipedia, and 9% used a hospital website. Most searched for general information about the surgery, followed by risks, pain/recovery, and specifics about the surgery. 69% reported that the information found influenced the healthcare decisions they made for their child. 86% felt the information was trustworthy. 21% discussed the information with their child's surgeon. 17% gathered information about their child's surgeon, of which 73% were interested in the surgeon's experience. 69% reported this influenced their choice of surgeon. CONCLUSIONS: Most parents of pediatric otolaryngologic patients use the Internet to gather information about their child's surgery, view that information as accurate, and use that information to make healthcare decisions. However, less than one quarter of parents discuss the information with their child's surgeon. It is critical to understand how parents use the Internet for healthcare information so otolaryngologists can better direct their patients' parents to appropriate and accurate resources.

Opioid use in pediatric otolaryngologic surgery: A survey of caregivers' attitudes.

OBJECTIVE: Given the current opioid epidemic and the fact that children continue to be undertreated for pain following surgeries, it is important to understand care-givers' attitudes toward post-operative opioid use. DESIGN: A survey was distributed to caregivers of pediatric patients undergoing otolaryngologic procedures. SETTING: An academic hospital in Boston, Massachusetts. PARTICIPANTS: Sixty-eight caregivers completed the survey. MAIN OUTCOME MEASURE: Caregiver attitudes toward post-operative opioid use. RESULTS: The study results are as follows: 38.1 percent of parents stated they would feel comfortable giving their child opioids post-operatively, 30.2 percent would not feel comfortable, and 31.7 percent were unsure. For every increase in 1 year of age of the child, there was an increase in the odds of a parent being comfortable giving opioids. Caregivers who had taken opioids in the past were more likely to feel comfortable, while those who were employed were less likely to feel comfortable. The most common reason reported for not feeling comfortable was addiction potential. The comfort level did not differ based on the caregivers' education level, income, race, or language. CONCLUSION: The majority of caregivers are unsure about or do not feel comfortable giving their child opioids post-operatively. Most are specifically concerned about the risk of addiction. Understanding caregivers' views on opioids in a diverse patient population is essential, so surgeons can counsel caregivers and provide appropriate post-operative pain management in their patients.

Assessing Loss to Follow-up After Newborn Hearing Screening in the Neonatal Intensive Care Unit: Sociodemographic Factors That Affect Completion of Initial Audiological Evaluation.

OBJECTIVES: Neonatal intensive care unit (NICU) patients are at high risk for congenital hearing loss. Previous studies have found sociodemographic factors associated with loss to follow-up for newborn hearing screening, but none have specifically studied the NICU population. Our objective is to determine if demographics and socioeconomic status is associated with loss to follow-up in a newborn population with extended NICU stay. DESIGN: A retrospective cohort study was conducted on 443 NICU infants with extended NICU stay utilizing data extracted from infant and maternal medical records at an urban safety-net hospital. RESULTS: Younger maternal age (adjusted odds ratio [OR] 0.95, confidence interval [CI] 0.91 to 0.99), higher gravidity (adjusted OR 1.39, CI 1.12 to 1.72), and former smoking status (adjusted OR 2.57, CI 1.07-6.18) were identified as independent predictors of loss to follow-up for NHS after conducting a multivariable logistic regression. Demographic and socioeconomic variables, such as sex, parity, birth weight, mode of birth, highest level of maternal education, maternal race/ethnicity, zip code metrics, and maternal language were not found to be associated with loss to follow-up. CONCLUSIONS: Maternal age, gravidity, and smoking status are risk factors for loss to follow-up for NHS in newborns with extended NICU stay, a group at high risk for hearing loss. Our findings demonstrate that socioeconomic and demographic factors for loss to follow-up in the extended-stay NICU population are distinct from the well-baby population. Further investigation of these patients will allow prioritization of limited resources to subgroups within the extended-stay NICU population at risk for loss to follow-up for newborn hearing screening.

Severe Versus Very Severe Pediatric Obstructive Sleep Apnea Outcomes After Adenotonsillectomy.

OBJECTIVES/HYPOTHESIS: Adenotonsillectomy (AT) is generally considered the first line treatment for pediatric patients with obstructive sleep apnea (OSA). Pediatric patients with severe OSA have worse outcomes after AT than patients with milder OSA. It is currently unclear if this group of higher morbidity patients should be subdivided further. This study investigates patients with severe pediatric OSA to determine if there are differences in postsurgical outcomes based on initial severity of sleep disordered breathing, medical comorbidities, or demographic factors. STUDY DESIGN: Retrospective cohort study at a single tertiary referral center. METHODS: Patients aged 2-18 who underwent polysomnogram (PSG) from October 2012 to January 2019, had an apnea-hypopnea index (AHI) >10, and subsequently underwent AT were identified using a filter through electronic medical record. A total of 112 patients underwent both pre- and postoperative PSG. Bivariate analysis was conducted via Pearson chi-square test. Univariate and multivariate analyses via binary logistic and multinomial linear regressions were performed using SPSS. RESULTS: Of the 112 patients included in this study, 68 patients were identified as having severe OSA (AHI = 10-20) and 44 as having very severe OSA (AHI > 20). Very severe OSA patients were significantly less likely to be cured of sleep disordered breathing or have their OSA reduced to mild OSA. Obese patients were found to have less reduction in AHI after AT. CONCLUSIONS: The postsurgical outcomes of patients with severe and very severe OSA are significantly different indicating that patients traditionally categorized as having severe OSA may need to be further subcategorized. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1855-1860, 2022.

The Relationship Between Obstructive Sleep Apnea and Pediatric Obesity: A Nationwide Analysis.

OBJECTIVE: Pediatric obstructive sleep apnea (OSA) can have both acute and chronic consequences when untreated. We hypothesize that a link exists between childhood obesity and OSA at nationwide level, with race, gender, and socioeconomic status conferring their own risk for pediatric OSA. METHODS: This study examined nationwide discharges in 2016 using the Kids' Inpatient Database (KID). The International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) codes for obesity (E66.0) and OSA (G47.33) were used. Prevalence rates and odds ratios (ORs) were used to quantify associations between the obesity and OSA groups in the general pediatric inpatient population. Multiple binary logistic regression was utilized to compare cohorts of pediatric inpatient admissions. RESULTS: There were 36 266 285 weighted discharges in the 2016 KID. Among patients included in our dataset, 0.426% (26 684) were diagnosed with obesity and 0.562% (35 242) had OSA. Obesity was independently associated with a significantly increased risk of OSA (OR = 22.89; 95% C.I. = 21.99-23.84). Within the OSA inpatient population, obesity was associated with non-Hispanic black race, Hispanic ethnicity, and Native American race/ethnicity (OR = 1.45, 1.32, 2.51; 95% C.I. = 1.33-1.58, 1.21-1.44, 1.73-3.63). CONCLUSIONS: Obesity is independently associated with OSA in children after controlling for adenotonsillar hypertrophy. Non-Hispanic black race and Hispanic ethnicity are independent risk factors for OSA and are associated with obesity in the OSA inpatient population, which suggests that obesity may play a role in the increased risk of OSA within these groups.

Landscape of Biomarkers in Non-small Cell Lung Cancer Using Comprehensive Genomic Profiling and PD-L1 Immunohistochemistry.

Comprehensive genomic profiling (CGP) and immunohistochemistry (IHC) are important biomarker tools used for patients with non-small cell lung cancer (NSCLC) given the expanding number of standard-of-care therapies that require companion diagnostic testing. We examined 9450 NSCLC real-world patient samples that underwent both CGP and programmed death-ligand 1 (PD-L1) IHC to understand the biomarker landscape in this patient cohort. By assessing National Comprehensive Cancer Network (NCCN)-recommended biomarkers including genomic alterations, tumor mutational burden (≥10 mutations/Mb cut-off), and PD-L1 expression (Tumor Proportion Score (TPS) ≥ 50% cut-off), we show that CGP + PD-L1 IHC yielded potentially actionable results for 70.5% of the 9,450 patients with NSCLC. Among the remaining 29.5% (2,789/9,450) of patients, 86.7% (2,419/2,789) were potentially eligible for another biomarker-associated therapy and/or clinical trial based on their genomic profile. In addition, in the PD-L1TPS≥50% disease subset, BRAF mutations, MET mutations, MET amplifications, and KRAS mutations were significantly enriched; and in the PD-L1TPS<50%, EGFR mutations, ERBB2 mutations, STK11 mutations, and KEAP1 mutations were enriched. These findings highlight the improved clinical utility of combining CGP with IHC to expand the biomarker-guided therapeutic options available for patients with NSCLC, relative to single biomarker testing alone.

The utility of ThyroSeq® in the management of indeterminate thyroid nodules by fine-needle aspiration.

OBJECTIVE: We aim to evaluate the impact of ThyroSeq® in the management of indeterminate thyroid nodules (ITN), including Bethesda III and IV nodules. METHODS: ITNs that underwent ThyroSeq testing between 2016 and 2019 were retrospectively reviewed. A control cohort included ITNs without molecular testing. Cytological, molecular, and histological data were collected. RESULTS: We identified 202 ITNs that underwent molecular testing (128 in Bethesda III and 74 in Bethesda IV). Mutations were found in 58 nodules with mutation rates of 21.9% in Bethesda III and 40.5% in Bethesda IV. In this cohort, 49 cases had surgical resection with a resection rate of 24.3% (49/202, 15.6% in Bethesda III and 39.2% in Bethesda IV). Among the resected cases, 42 cases had positive molecular results. Thyroid cancer was diagnosed in 21 nodules with a malignancy detection rate of 10.4%. In the other cohort, we identified 236 ITNs (158 in Bethesda III and 78 in Bethesda IV). Surgical resection was performed in 127 cases, with a resection rate of 53.8% (127/236, 46.2% in Bethesda III and 69.2% in Bethesda IV). Thyroid cancer was diagnosed in 21 nodules, with a malignancy detection rate of 8.9%. The risk of malignancy (ROM) recalculated based on positive ThyroSeq results was significantly higher (21.4%-35.5% in Bethesda III and 50%-60% in Bethesda IV) than that without molecular testing (4.4%-9.6% in Bethesda III and 17.9%-25.9% in Bethesda IV). CONCLUSION: We concluded that ThyroSeq significantly decreased the surgical resection rate (from 53.8% to 24.3%) without significantly affecting the malignancy detection rate in ITNs. Furthermore, positive molecular testing significantly increased ROM in ITNs. We believe that the recalculated ROM should be incorporated into the management of ITNs.

Predictors of a Normal Sleep Study in Healthy Children with Sleep Disordered Breathing Symptoms.

OBJECTIVE: To determine the prevalence and characteristics of children with normal elective polysomnography for obstructive sleep disordered breathing (oSDB) based on the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines. STUDY DESIGN: In this retrospective cohort study, we identified patients ages 2 to 18 who underwent diagnostic polysomnography (PSG) ordered by our otolaryngology department for SDB between 2012 and 2018. SETTING: All patients were seen by otolaryngologists at an urban tertiary safety net hospital. SUBJECTS AND METHODS: There were a total of 456 patients studied (average age 5.66 ± 3.19; 263 (57.7%) males, 193 (42.3%) females. Demographic factors (age, gender, race, ethnicity, language, insurance status) and clinical findings (symptom severity, tonsil size) were recorded. The data were analyzed by univariate and multivariate analysis. RESULTS: Two hundred four patients (44.7%) had no obstructive sleep apnea (OSA) based on AHI<2 on PSG. Children with a larger tonsil size had 3.18 times the odds of OSA compared to those with a medium tonsil size (95% CI 1.64, 6.19) when adjusting for symptoms, age category, and race (P = .0007). Children ages 4 to 6 years had 0.25 times the odds of OSA compared to those ages 2-3 years (95% CI 0.12, 1.54) when adjusting for symptoms, tonsil size, and race (P = .0011). White children had 0.28 times the odds of OSA compared to Black children (95% CI 0.14, 0.57) when adjusting for symptoms, tonsil size, and age category (P = .0004). CONCLUSION: Among our patient population, 44.7% had normal sleep studies. Younger children (ages 2-3) were less likely to have normal polysomnography. This research demonstrates that obtaining sleep studies in otherwise healthy children with SDB can affect management decisions, and they should be discussed with families with a focus on patient centered decision making.

Assessing the Educational Quality of Facebook Videos as an Informative Resource on Otitis Media.

OBJECTIVE: This study analyzes the quality and reliability of otitis media (OM) videos on Facebook and investigates whether the videos shared within the Facebook community are considered to be a valuable educational tool. The results of this study are important for providing clinicians with the necessary understanding about the video content that their patients may be exposed to. STUDY DESIGN: Cross-sectional analysis of video content. SETTING: A new Facebook account was created to carry out a search for videos on OM. METHODS: Inclusion criteria were as follows: videos intended for educating patients or guardians on OM, videos in the English language, and videos with at least 1 share. RESULTS: A total of 364 videos were screened, and 62 fit our inclusion criteria for analysis. The majority (56%) of OM videos on Facebook focused on complementary and alternative medication without mentioning any current guidelines. A limited amount of videos (29%) made any mention to surgical treatment options for OM. There was a strong positive correlation (rho = 0.8419, P < .001) between a video's content and its reliability. There was no correlation seen between a video's content and its shares (rho = -0.142, P = .1359). CONCLUSIONS: The majority of OM videos on Facebook are inadequate for educational value. Clinicians should know about the existence of videos on OM and the quality of information that parents are exposed to.

Locally invasive, castrate-resistant prostate cancer in a Pten/Trp53 double knockout mouse model of prostate cancer monitored with non-invasive bioluminescent imaging.

Here we have improved an existing mouse model of prostate cancer based on prostate-specific deletion of Pten and Trp53 by incorporating a Cre-activatable luciferase reporter. By coupling the deletion of those genes to the activation of a luciferase reporter, we were able to monitor tumor burden non-invasively over time. We show that, consistent with previous reports, deletion of both Pten and Trp53 on a C57BL/6 background accelerates tumor growth and results in both the loss of androgen receptor expression and castrate resistant tumors as compared with loss of Pten alone. Loss of Trp53 results in the development of sarcomatoid histology and the expression of markers of epithelial-to-mesenchymal transition Zeb1 and vimentin, with kinetics and penetrance dependent on whether one or both alleles of Trp53 were deleted. Homozygous deletion of Trp53 and Pten resulted in uniformly lethal disease by 25 weeks. While we were able to detect locally invasive disease in the peritoneal cavity in aggressive tumors from the double knockout mice, we were unable to detect lymphatic or hematogenous metastatic disease in lymph nodes or at distant sites.

Robot-assisted epiglottopexy as a method for managing adult obstructive sleep apnea.

INTRODUCTION: Patients who do not tolerate continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSA) often seek surgical management. A variety of procedures exist to address the nasal passages, oropharynx, hypopharynx, and larynx. Diagnostic studies including drug-induced sleep endoscopy (DISE) are helpful in identifying areas of obstruction. One potential site of obstruction is at the level of the epiglottis. We describe the use of robotic technology to assist with epiglottopexy to manage epiglottic retroflexion as a cause of two patients' OSA. This is the first reported robot-assisted epiglottopexy in the adult otolaryngology literature. METHODS: This is a case series of two patients with OSA who demonstrated epiglottis collapse into the airway during DISE. They were evaluated by polysomnographic testing (PSG), Epworth Sleepiness Scale (ESS), and physical exam. Given their epiglottic collapse seen on DISE, they underwent robot-assisted epiglottopexy. RESULTS: Both patients had moderate to severe OSA preoperatively. They successfully underwent robot-assisted epiglottopexy as a surgical intervention. They tolerated the procedure, and there have been no complications. Each reported improved symptoms, with patient one showing a decrease in total AHI and a substantial decrease in oxygen desaturations at night. The second patient reported a significant decrease in AHI and ESS. CONCLUSION: There are many options for surgical intervention in patients with OSA. Epiglottopexy is one method for addressing collapse of the epiglottis and can be achieved successfully through robot-assisted epiglottopexy in adult patients with OSA. LEVEL OF EVIDENCE: IV.

Biomarkers in Breast Cancer: An Integrated Analysis of Comprehensive Genomic Profiling and PD-L1 Immunohistochemistry Biomarkers in 312 Patients with Breast Cancer.

BACKGROUND: We examined the current biomarker landscape in breast cancer when programmed death-ligand 1 (PD-L1) testing is integrated with comprehensive genomic profiling (CGP). MATERIAL AND METHODS: We analyzed data from samples of 312 consecutive patients with breast carcinoma tested with both CGP and PD-L1 (SP142) immunohistochemistry (IHC) during routine clinical care. These samples were stratified into hormone receptor positive (HR+)/human epidermal growth factor receptor negative (HER2-; n = 159), HER2-positive (n = 32), and triple-negative breast cancer (TNBC) cohorts (n = 121). RESULTS: We found that in the TNBC cohort, 43% (52/121) were immunocyte PD-L1-positive, and in the HR+/HER2- cohort, 30% (48/159) had PIK3CA companion diagnostics mutations, and hence were potentially eligible for atezolizumab plus nab-paclitaxel or alpelisib plus fulvestrant, respectively. Of the remaining 212 patients, 10.4% (22/212) had a BRCA1/2 mutation, which, if confirmed by germline testing, would allow olaparib plus talazoparib therapy. Of the remaining 190 patients, 169 (88.9%) were positive for another therapy-associated marker or a marker that would potentially qualify the patient for a clinical trial. In addition, we examined the relationship between immunocyte PD-L1 positivity and different tumor mutation burden (TMB) cutoffs and found that when a TMB cutoff of ≥9 mutations per Mb was applied (cutoff determined based on prior publication), 11.6% (14/121) patients were TMB ≥9 mutations/Mb and of these, TMB ≥9 mutations per Mb, 71.4% (10/14) were also positive for PD-L1 IHC. CONCLUSION: Our integrated PD-L1 and CGP methodology identified 32% of the tested patients as potentially eligible for at least one of the two new Food and Drug Administration approved therapies, atezolizumab or alpelisib, and an additional 61.2% (191/312) had other biomarker-guided potential therapeutic options. IMPLICATIONS FOR PRACTICE: This integrated programmed death-ligand 1 immunohistochemistry and comprehensive genomic profiling methodology identified 32% of the tested patients as eligible for at least one of the two new Food and Drug Administration-approved therapies, atezolizumab or alpelisib, and an additional 61.2% (191/312) had other biomarker-guided potential therapeutic options. These findings suggest new research opportunities to evaluate the predictive utility of other commonly seen PIK3CA mutations in hormone receptor-positive breast cancers and to standardize tumor mutation burden cutoffs to evaluate its potentially predictive role in triple-negative breast cancer.

Lemierre's syndrome in the pediatric population: Trends in disease presentation and management in literature.

OBJECTIVE: This study aims to examine literature on Lemierre's Syndrome (LS) in the pediatric population over time in order to describe patterns in disease progression, management, and prognosis. In addition, this study assesses specific rate of literature output and the location of research over the past 10 years. METHODS: A literature review was conducted through two databases, PubMed.gov and PMC. A search was conducted using the keywords "Lemierre syndrome" and "postanginal sepsis." Literature was primarily reviewed for demographic, radiographic, and clinical data. Articles were included in the study if they were published in English and within the last 10 years. All types of research studies were recorded, however primary data collection came from case reports and series. Publications were grouped into two time periods: 2009-2013 and 2014-2019, allowing for comparison of various characteristics between these two groups. RESULTS: A total of 124 research studies on LS met inclusion criteria and were reviewed. Of these, 98 case reports (79.0%) were examined. Disease Characteristics: Fusobacterium necrophorum was the most common precipitating pathogen isolated from cultures (66.2%). The main primary treatment modalities used were antimicrobials, surgery, anticoagulation, or a combination of these treatments. A total of 63.9% of the case reports indicated use of anticoagulation at some point during treatment. Publication Trends: The number of published studies has not significantly changed in the last decade, with a non-statistically significant decline of 5.6%, when comparing 2014-2019 to 2009-2013 (p = 0.21). Case reports/series were the most common study design (82.2% vs 69.5%) and level of evidence for published studies continued to be stable (level 4-5) through the years (86.9%). The number of publications within an international journal vs US based journal has also remained steady during both time periods (p = 0.698). CONCLUSION: LS is an uncommon condition but one that is important for physicians to be aware of in the pediatric population. Treatment regimens including antibiotics and anticoagulation have remained stable through the past 10 years, however the efficacy of anticoagulation in treating LS continues to be debated. Though LS is considered a severe illness with potentially life threatening complications, publications on this topic, in pediatrics specifically, have decreased within the past five years.

Reevaluation of the US Pathologist Workforce Size.

Importance: There is currently no national organization that publishes its data that serves as the authoritative source of the pathologist workforce in the US. Accurate physician numbers are needed to plan for future health care service requirements. Objective: To assess the accuracy of current pathologist workforce estimates in the US by examining why divergency appears in different published resources. Design, Setting, and Participants: This study examined the American Board of Pathology classification for pathologist primary specialty and subspecialties and analyzed previously published reports from the following data sources: the Association of American Medical Colleges (AAMC), the Accreditation Council for Graduate Medical Education (ACGME), a 2013 College of American Pathologists (CAP) report, a commercially available version of the American Medical Assoication (AMA) Physician Masterfile, and an unpublished data summary from June 10, 2019. Main Outcomes and Measures: Number of physicians classified as pathologists. Results: The most recent AAMC data from 2017 (published in 2018) reported 12 839 physicians practicing "anatomic/clinical pathology," which is a subset of the whole. In comparison, the current AMA Physician Masterfile, which is not available publicly, listed 21 292 active pathologists in June 2019. The AMA Physician Masterfile includes all pathologists in 15 subspecialized training areas as identified by the ACGME. By contrast, AAMC's data, which derive from the AMA Physician Masterfile data, only count physicians primarily associated with 3 general categories of pathologists and 1 subspecialty category (ie, chemical pathology). Thus, the AAMC pathology workforce estimate does not include those whose principal work is in 11 subspecialty areas, such as blood banking or transfusion medicine, cytopathology, hematopathology, or microbiology. An additional discrepancy relates to the ACGME residency (specialties) and fellowship (subspecialties) training programs in which pathologists with training in dermatopathology appear as dermatologists and pathologists with training in molecular genetic pathology appear as medical geneticists. Conclusions and Relevance: This analysis found that most sources reported only select categories of the pathologist workforce rather than the complete workforce. The discordant nature of reporting may pertain to other medical specialties that have undergone increased subspecialization during the past 2 decades (eg, surgery and medicine). Reconsideration of the methods for determining the pathologist workforce and for all workforces in medicine appears to be needed.

Socioeconomic variables as a predictor of indication for pediatric adenotonsillectomy.

OBJECTIVES: Adenotonsillectomy (AT) is a common pediatric procedure performed for sleep disordered breathing (SDB) or chronic/recurrent tonsillitis. A better understanding of factors associated with clinical indications for AT would positively contribute to patient-centered care of these conditions. Our objective is to assess the relationships between race, ethnicity, and socioeconomic status (SES) and indications for adenotonsillectomy in pediatric patients. METHODS: A retrospective chart review was conducted for pediatric patients between the ages 0-18 years who underwent adenotonsillectomy between October 2012 and October 2017 at Boston Medical Center. Indication for surgery was categorized as sleep disordered breathing (SDB), tonsillitis, or other. Age, race, ethnicity, gender, language, distance to hospital and insurance type were collected as demographic variables. 9-Digit patient zip codes were matched to a corresponding area deprivation index (ADI) which combines 17 neighborhood level socioeconomic markers. Logistic regression analysis was performed to assess for association between demographic variables and indication for adenotonsillectomy. RESULTS: 1315 children were included in this study (mean age = 6.4 years, 0-18 years). African American (OR = 3.90, p-value <0.0001), Latino (OR = 2.602, p-value < 0.0001), and Asian American (OR = 4.439, p-value = 0.0146) patients were more likely to have SDB as an indication than Caucasian patients. Among children undergoing AT for SDB, patients who received pre-operative polysomnogram were more likely to be under 2 years old, African American, Asian American, or of Hispanic ethnicity and have higher BMI than patients who were diagnosed clinically prior to surgery. There was no statistically significant association between indications for adenotonsillectomy and ADI, distance to hospital, insurance status or language. Males were more likely have to have SDB as an indication than females (OR = 1.67, p-value = 0.0014). Younger patients under two years of age were more likely to have SDB as an indication for surgery when compared to older patients. CONCLUSION: We found significant relationships between indications for adenotonsillectomy and race and ethnicity as well as gender and age. Additionally, our study showed that indication for AT was not associated with either ADI or insurance status. This suggests that race and ethnicity are predictors of indication independent of SES. Knowledge of predictive factors of adenotonsillectomy indications may help to improve patient centered care.

Characteristics and Frequency of Children With Severe Obstructive Sleep Apnea Undergoing Elective Polysomnography.

OBJECTIVE: To determine the prevalence and demographics features of pediatric patients with severe obstructive sleep apnea (OSA) who would not undergo preoperative polysomnography (PSG) under current American Academy of Otolaryngology (AAO) guidelines. STUDY DESIGN: In this retrospective cohort study, we identified patients from the electronic medical record who underwent elective polysomnography for evaluation of sleep-disordered breathing between 2012 and 2018. SETTING: Urban tertiary safety net hospital. SUBJECTS AND METHODS: A total of 456 patients with a mean (SD) age of 5.7 (3.2) years (263 male, 193 female). Demographic factors (age, sex, race, language, insurance status) and clinical findings (symptom severity, tonsil size) were recorded. The data were analyzed by univariate analysis. RESULTS: Of 456 patients identified, 66 (14.5%) were found to have severe OSA. African American patients had 3.7 times the odds of severe OSA compared to white patients (95% CI, 1.2-10.8). Patients aged 2 to 3 years had 2.2 times the odds of severe OSA compared to patients aged 4 to 6 years (95% CI, 1.2-4.0). Sex, ethnicity, language, and insurance type were not significantly associated with severity of OSA. The presence of apneic episodes and tonsil size were not found to be statistically significant. CONCLUSION: Up to 14.5% of healthy pediatric patients with sleep-disordered breathing may have severe OSA; young age and African American race are statistically significant predictors. Clinical findings, such as tonsil size and symptom severity, were not found to be statistically significant predictors.
