Impact of social determinants of health on access to rhinology care and patient outcomes: A pilot study.

Objective: This novel pilot study constructs a social deprivation index (SDI) and utilizes an area deprivation index (ADI) to evaluate the link between social determinants of health and rhinology patient experiences. Methods: Adult patients undergoing outpatient care of chronic rhinitis and chronic rhinosinusitis at a tertiary academic medical center were recruited to participate in a telephone survey assessing symptoms, social/emotional consequences of disease, and barriers to care on a 5-point Likert scale. Sociodemographic characteristics were utilized to rate SDI on an 8-point scale. ADI was obtained by area code of residence. Ordered logistic regression was used to examine associations between the SDI/ADI and perceptions of rhinology care. Results: Fifty patients were included. Individuals with higher SDI scores (i.e., more socially deprived) experienced more severe nasal congestion (p = .007). Furthermore, higher national ADI correlated with increased severity of smell changes (p = .050) and facial pressure (p = .067). No association was seen between either deprivation index and global/psychiatric symptoms. While no correlations were found between higher SDI and difficulties with the costs of prescriptions, rhinologist's visits, or saline, higher SDI was correlated with decreased difficulty with surgery costs (p = .029), and individuals with higher national ADI percentile had increased difficulties obtaining nasal saline (p = .029). Conclusion: Worse social deprivation is associated with difficulties obtaining saline rinses and increased severity of nasal/sinus symptoms in an urban, underserved, majority-Black population. These findings suggest social factors affect access to and quality of rhinology care in a complex and nuanced way and highlight the need for a specific SDI to further study social determinants of health in rhinology.

Systematic Review of Nonsyndromic Craniosynostosis: Genomic Alterations and Impacted Signaling Pathways.

BACKGROUND: Genetic research in nonsyndromic craniosynostosis remains limited compared with syndromic craniosynostosis. This systematic review aimed to comprehensively summarize the genetic literature of nonsyndromic craniosynostosis and highlight key signaling pathways. METHODS: The authors performed a systematic literature search of PubMed, Ovid, and Google Scholar databases from inception until December of 2021 using search terms related to nonsyndromic craniosynostosis and genetics. Two reviewers screened titles and abstract for relevance, and three reviewers independently extracted study characteristics and genetic data. Gene networks were constructed using Search Tool for Retrieval of Interacting Genes/Proteins (version 11) analysis. RESULTS: Thirty-three articles published between 2001 and 2020 met inclusion criteria. Studies were further classified into candidate gene screening and variant identification studies ( n = 16), genetic expression studies ( n = 13), and common and rare variant association studies ( n = 4). Most studies were good quality. Using our curated list of 116 genes extracted from the studies, two main networks were constructed. CONCLUSIONS: This systematic review concerns the genetics of nonsyndromic craniosynostosis, with network construction revealing TGF-ß/BMP, Wnt, and NF-κB/RANKL as important signaling pathways. Future studies should focus on rare rather than common variants to examine the missing heritability in this defect and, going forward, adopt a standard definition.

Imbrication of Anterior Digastric with Advancement of the Posterior Digastric and Its Implications in Neck Aesthetics.

Background: To describe a novel technique to modify the proportional length of the anterior-to-posterior digastric muscles to improve neck aesthetics. Objective: To provide an objective measure to quantify neck rejuvenation and a novel technique to adjust the digastric ratio. Design: We retrospectively compared 52 patients who had neck rejuvenation with or without digastric manipulation. Preoperative and postoperative images were analyzed and compared with computer software using a novel analysis technique to measure the digastric ratio and neck height. Distances between the menton, cervical point (CP), and gonion were measured. Results: The anterior-to-posterior digastric ratio improved an average of 26.5% (p < 0.01) in the new technique group, 15.9% in the control group. Distance of the CP to the inferior edge of the mandible decreased an average of 13.9% using the new technique. Conclusion: The ratio of anterior-to-posterior digastric muscle appears to improve as well as the neck height with manipulation of the digastric muscles.

Health Insurance Coverage and Survival Outcomes among Nasopharyngeal Carcinoma Patients: A SEER Retrospective Analysis.

Objectives Insurance coverage plays a critical role in head and neck cancer care. This retrospective study examines how insurance coverage affects nasopharyngeal carcinoma (NPC) survival in the United States using the Surveillance, Epidemiology, and End Results (SEER) program database. Design, Setting, and Participants A total of 2,278 patients aged 20 to 64 years according to the International Classification of Diseases for Oncology (ICD-O) codes C11.0-C11.9 and ICD-O histology codes 8070-8078 and 8080-8083 between 2007 and 2016 were included and grouped into privately insured, Medicaid, and uninsured groups. Log-rank test and multivariable Cox's proportional hazard model were performed. Main Outcome Measures Tumor stage, age, sex, race, marital status, disease stage, year of diagnosis, median household county income, and disease-specific survival outcomes including cause of death were analyzed. Results Across all tumor stages, privately insured patients had a 59.0% lower mortality risk than uninsured patients (hazard ratio [HR]: 0.410, 95% confidence interval [CI]: [0.320, 0.526], p < 0.01). Medicaid patients were also estimated to have 19.0% lower mortality than uninsured patients (HR: 0.810, 95% CI: [0.626, 1.048], p = 0.108). Privately insured patients with regional and distant NPC had significantly better survival outcomes compared with uninsured individuals. Localized tumors did not show any association between survival and type of insurance coverage. Conclusion Privately insured individuals had significantly better survival outcomes than uninsured or Medicaid patients, a trend that was preserved after accounting for tumor grade, demographic and clinicopathologic factors. These results underscore the difference in survival outcomes when comparing privately insured to Medicaid/uninsured populations and warrant further investigation in efforts for health care reform.

Determining the association of insurance coverage and survival outcomes in patients with olfactory neuroblastoma utilizing machine learning.

KEY POINTS: We use machine learning to examine health insurance and mortality in olfactory neuroblastoma. Private insurance significantly improved survival even after adjusting for confounders. The regression model also found no statistical difference between Medicare and no insurance.

Microbial Changes Associated With Oral Cavity Cancer Progression.

OBJECTIVE: To examine the oral microbiome in the context of oral cavity squamous cell carcinoma. STUDY DESIGN: Basic science research. SETTING: Academic medical center. METHODS: Oral swabs were collected from patients presenting to the operating room for management of oral cavity squamous cell carcinoma and from age- and sex-matched control patients receiving surgery for unrelated benign conditions. 16S ribosomal RNA (rRNA) sequencing was performed on genetic material obtained from swabs. A bacterial rRNA gene library was created and sequence reads were sorted into taxonomic units. RESULTS: Thirty-one control patients (17 males) and 35 cancer patients (21 males) were enrolled. Ages ranged from 23 to 89 (median 63) for control patients and 35 to 86 (median 66) for cancer patients. Sixty-one percent of control patients and 63% of cancer patients were smokers. 16S analyses demonstrated a significant decrease in Streptococcus genera in oral cancer patients (34.11% vs 21.74% of the population, p = .04). Increases in Fusobacterium, Peptostreptococcus, Parvimonas, and Neisseria were also found. The abundance of these bacteria correlated with tumor T-stage. CONCLUSION: 16S rRNA sequencing demonstrated changes in bacterial populations in oral cavity cancer and its progression compared to noncancer controls. We found increases in bacteria genera that correspond with tumor stage-Fusobacteria, Peptostreptococcus, Parvimonas, Neisseria, and Treponema. These data suggest that oral cancer creates an environment to facilitate foreign bacterial growth, rather than implicating a specific bacterial species in carcinogenesis. These bacteria can be employed as a potential marker for tumor progression or interrogated to better characterize the tumor microenvironment.

Pasteurella multocida bacteremia: A case report of pelvic cavity inflammation with abnormal uterine bleeding, fever, and sclerotic bone lesions.

Background: Pasteurella multocida, is a bacterium that is frequently transmitted to humans from domestic pets. Infections are generally localized, but previous reports have exhibited that Pasteurella can cause systemic infections such as peritonitis, bacteremia and in some rare cases tubo-ovarian abscess. Case presentation: We present a case of a 46-year-old woman who came to the emergency department (ED) with complaints of pelvic pain, abnormal uterine bleeding (AUB), and fever. A non-contrast computed tomography (CT) of abdomen and pelvis showed uterine fibroids with sclerotic changes in lumbar vertebrae and pelvic bones causing a high degree of suspicion for cancer. On admission, blood culture, complete blood count (CBC) and tumor markers were drawn. Additionally, an endometrial biopsy was performed to rule out the possibility of endometrial cancer (EC). The patient underwent an exploratory laparoscopy with hysterectomy and bilateral salpingectomy. After diagnosis with P. multocida the patient was treated with five days of Meropenem. Conclusion: There are few cases of P. multocida peritonitis reported; in addition, findings of AUB with sclerotic bony changes in a middle-aged woman is often associated with EC. Thus, clinical suspicion from patient history, infectious disease work-up and diagnostic laparoscopy are essential for proper diagnosis and management.

Outcomes of Total Knee and Hip Arthroplasty in Patients With Perioperative Thrombocytopenia.

BACKGROUND: Thrombocytopenia is an abnormally low level of blood platelets (less than 150,000/mL) resulting in an increased risk for bleeding. Typically, patients with platelet levels below 50,000/mL should delay arthroplasty or be transfused with platelets before surgery. However, existing studies are mixed regarding the effects of more moderate thrombocytopenia in terms of total knee and hip arthroplasty outcomes. METHODS: This level III retrospective chart review examined the effects of different severities of preoperative thrombocytopenia on length of hospitalization, readmission, and transfusion rates in 5,617 primary total knee and hip arthroplasties at one tertiary academic medical center. Preoperative platelet levels were sectioned into clinically relevant groups and compared with clinical outcomes using univariable and multivariable models. RESULTS: On univariate analysis, having platelet levels of <100,000/mL and 100 to 149,000/mL was associated with a longer length of stay. However, after controlling individual demographics, there was no association between platelet levels and length of stay, nor with 30-day readmission. Finally, on univariate analysis, patients with platelet levels of <100,000/mL and 100 to 149,000/mL were more likely to have a blood transfusion, which remained true for those with <100,000/mL after controlling for individual demographics. CONCLUSIONS: Total hip and total knee arthroplasty are safe in patients with varying platelet levels and not associated with increased length of stay or 30-day readmission. However, patients with more severe thrombocytopenia are more likely to receive red blood cell transfusions than patients with milder thrombocytopenia.

Embolization in Juvenile Nasopharyngeal Angiofibroma Surgery: A Systematic Review and Meta-Analysis.

OBJECTIVE: To compare outcomes of juvenile nasopharyngeal angiofibroma (JNA) resection between embolized and non-embolized cohorts, and between transarterial embolization (TAE) and direct puncture embolization (DPE). DATA SOURCES: Per PRISMA guidelines, PubMed, Embase, Web of Science, Scopus, and Cochrane databases were searched for publications prior to or in 2021. MATERIALS AND METHODS: Original English manuscripts investigating the resection of JNA with and without preoperative embolization were included. Embolization type, recurrence rate, complication rates, blood loss, and transfusions were extracted. Risk of bias was assessed by the Risk of Bias in Non-randomized Studies-of Interventions method. RESULTS: There were 61 studies with 917 patients included. Preoperative embolization was performed in 79.3% of patients. Of those embolized, 75.8% (N = 551) underwent TAE and 15.8% (N = 115) underwent DPE. JNA recurrence in embolized patients was lower than in non-embolized patients (9.3% vs. 14.4%; odds ratio [OR]: 0.61, 95% confidence interval [CI]: 0.35, 1.06). DPE resulted in lower rates of disease recurrence (0% vs. 9.5%; OR: 0.066, 95% CI: 0.016, 0.272) and complications (1.8% vs. 21.9%; OR: 0.07, 95% CI: 0.02, 0.3) than TAE. A random effects Bayesian model was performed to analyze the difference in mean blood loss in 6 studies that included both embolized and non-embolized patients. This analysis showed a mean reduction in blood loss of 798 mL in the embolized group. CONCLUSIONS: We found embolization decreases blood loss in JNA resection. DPE led to improved recurrence and complication rates when compared to TAE, but future prospective studies are needed to further evaluate which embolization technique can optimize outcomes in JNA.

Right Vocal Cord Paralysis Caused by Histoplasmosis: A Case Report.

OBJECTIVES: Histoplasma capsulatum is a prevalent dimorphic fungus, reaching an exposure rate of 90% in endemic areas such as the Midwest and Central United States. We report an unusual presentation of dysphonia due to right vocal cord paralysis caused by mediastinal lymphadenopathy from histoplasmosis. METHODS: A 73-year-old male presented to an otolaryngology clinic with 4 months of hoarseness. Flexible strobolaryngoscopy demonstrated right vocal cord paralysis in lateral position and a full length glottic gap. Computerized tomography (CT) scan showed enlargement of a right paratracheal node. RESULTS: A lymph node biopsy was obtained and showed histoplasmosis. He was treated with a 3-month course of pozaconazole. He then received a vocal cord medialization injection 2 months after symptom onset, which produced favorable improvement of his symptoms at 8-month follow up. CONCLUSIONS: One other case report in the literature has reported left vocal cord paralysis related to histoplasmosis. This first case of right vocal cord paralysis was extremely unusual and is not often included in the differential diagnosis of vocal cord paralysis.

Laryngeal and pharyngeal actinomycosis: a systematic review and report of 3 cases.

INTRODUCTION: Actinomycosis is a granulomatous infection that rarely involves the larynx or pharynx. Three cases of actinomycosis of the larynx or pharynx from our institution were reviewed and a systematic literature review was performed to better define surgical management, antibiotic therapy, risk factors, and incidence of recurrence or complications. MATERIALS AND METHODS: PubMed/Medline, Cochrane, Embase, and Google Scholar were searched on November 30, 2021 using the terms "laryngeal actinomycosis", "pharyngeal actinomycosis", "actinomycosis AND larynx", and "actinomycosis AND pharynx." Articles which did not describe appropriate sites or were non-English were excluded. Results were collected for demographic information, site(s) of infection, comorbidities, lesion characteristics and treatments. RESULTS: Along with three cases reported from our institution, 40 unique cases were reviewed from 37 studies for a total of 43 patients (Table 1). 34 (81.0 %) of the patients were male with the highest incidence of infection in the seventh decade (54.8 %). The most common site for the infection was the larynx (69.0 %) followed by the pharynx (16.7 %). Risk factors included a history of radiation therapy, immunosuppression, inhalational irritant, and diabetes (Table 3). The duration of antibiotic therapy varied greatly, from one month to one year and total follow up ranged from 1 month to 2.5 years (Table 1). CONCLUSIONS: A comprehensive review of the literature on pharyngolaryngeal actinomycosis shows that this infection has increased prevalence within the head and neck cancer patient population. Similar to cervicofacial actinomycosis, these atypical sites have shown favorable responses to extended antibiotic therapy and generally do not require aggressive surgical management.

Large non-functioning substernal parathyroid cyst: A case report and review of the literature.

OBJECTIVES: Parathyroid cysts are rare benign lesions of the head and neck that account for less than 1% of cystic neck masses. We present a rare case of a large 6 cm substernal parathyroid cyst. PRESENTATION OF CASE: An otherwise healthy 65 year-old female presented to the otolaryngology clinic for evaluation of an anterior, midline neck mass. On physical exam, she was noted to have a fullness in the anterior neck extending to the sternal notch. CT demonstrated an enlarged thyroid with a cyst extending to the aortic arch. Initial evaluation suggested a bilateral goiter with substernal extension. The cyst was managed with drainage and observation. After two years of continued growth, the patient underwent a left thyroid lobectomy and mediastinal mass resection via the cervical approach. Final pathology was consistent with a parathyroid cyst. CONCLUSIONS: Parathyroid cysts are a rare cause of neck mass in an adult, and a 6 cm substernal parathyroid cyst represents an unusual site and size for these cysts. Parathyroid cysts are not often considered on the differential of neck and mediastinal cystic lesions. However, appropriate steps should be taken to ensure a proper diagnosis for any cystic lesion in the neck.

Large tracheoesophageal granular cell tumor: An atypical case presentation, location, and management.

INTRODUCTION: Granular cell tumors (GCT) are rare tumors that most frequently present in the oral cavity. While some present within the gastrointestinal tract, a GCT near the trachea is an extremely rare occurence. PRESENTATION OF CASE: A 42-year-old man presented to the Emergency Department after a motor vehicle accident. A computerized tomography (CT) scan revealed an incidental soft tissue 3.2 × 5.5 cm mass anterior to the esophagus and posterior to the trachea with no adjacent lymphadenopathy. The patient denied dyspnea, voice changes, or dysphagia. Due to its size and location, the patient underwent a transcervical excision of the retrotracheal tumor. Tumor cells were positive for CD68, CD163, S100, and SOX10, confirming a GCT. CONCLUSION: This is a distinctive presentation of a large (5 cm) GCT in the plane between the trachea and esophagus. GCTs are not often on the differential diagnosis of masses that present in this region.

Pulmonary Parenchymal Changes in COVID-19 Survivors.

BACKGROUND: As the COVID-19 pandemic moves into the survivorship phase, questions regarding long-term lung damage remain unanswered. Previous histopathologic studies are limited to autopsy reports. We studied lung specimens from COVID-19 survivors who underwent elective lung resections to determine whether postacute histopathologic changes are present. METHODS: This multicenter observational study included 11 adult COVID-19 survivors who had recovered but subsequently underwent unrelated elective lung resection for indeterminate lung nodules or lung cancer. We compared these against an age- and procedure-matched control group who never contracted COVID-19 (n = 5) and an end-stage COVID-19 group (n = 3). A blinded pulmonary pathologist examined the lung parenchyma focusing on 4 compartments: airways, alveoli, interstitium, and vasculature. RESULTS: Elective lung resection was performed in 11 COVID-19 survivors with asymptomatic (n = 4), moderate (n = 4), and severe (n = 3) COVID-19 infections at a median 68.5 days (range 24-142 days) after the COVID-19 diagnosis. The most common operation was lobectomy (75%). Histopathologic examination identified no differences between the lung parenchyma of COVID-19 survivors and controls across all compartments examined. Conversely, patients in the end-stage COVID-19 group showed fibrotic diffuse alveolar damage with intra-alveolar macrophages, organizing pneumonia, and focal interstitial emphysema. CONCLUSIONS: In this study to examine the lung parenchyma of COVID-19 survivors, we did not find distinct postacute histopathologic changes to suggest permanent pulmonary damage. These results are reassuring for COVID-19 survivors who recover and become asymptomatic.

Neuronal and Endothelial Transglutaminase-2 Expression during Experimental Autoimmune Encephalomyelitis and Multiple Sclerosis.

Transglutiminase-2 (TG2) is a multifunctional enzyme that has been implicated in the pathogenesis of experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) using global knockout mice and TG2 selective inhibitors. Previous studies have identified the expression of TG2 in subsets of macrophages-microglia and astrocytes after EAE. The aims of the current investigation were to examine neuronal expression of TG2 in rodent models of chronic-relapsing and non-relapsing EAE and through co-staining with intracellular and cell death markers, provide insight into the putative role of TG2 in neuronal pathology during disease progression. Here we report that under normal physiological conditions there is a low basal expression of TG2 in the nucleus of neurons, however following EAE or MS, robust induction of cytoplasmic TG2 occurs in most neurons surrounding perivascular lesion sites. Importantly, TG2-positive neurons also labeled for phosphorylated Extracellular signal-regulated kinase 1/2 (ERK1/2) and the apoptotic marker cleaved caspase-3. In white and gray matter lesions, high levels of TG2 were also found within the vasculature and endothelial cells as well as in tissue migrating pericytes or fibroblasts, though rarely did TG2 colocalize with cells identified with glial cell markers (astrocytes, oligodendrocytes and microglia). TG2 induction occurred concurrently with the upregulation of the blood vessel permeability factor and angiogenic molecule Vascular Endothelial Growth Factor (VEGF). Extracellular TG2 was found to juxtapose with fibronectin, within and surrounding blood vessels. Though molecular and pharmacological studies have implicated TG2 in the induction and severity of EAE, the cell autonomous functions of this multifunctional enzyme during disease progression remains to be elucidated.
