RESUMO

Maackia amurensis lectins serve as research and botanical agents that bind to sialic residues on proteins. For example, M. amurensis seed lectin (MASL) targets the sialic acid modified podoplanin (PDPN) receptor to suppress arthritic chondrocyte inflammation, and inhibit tumor cell growth and motility. However, M. amurensis lectin nomenclature and composition are not clearly defined. Here, we sought to definitively characterize MASL and its effects on tumor cell behavior. We utilized SDS-PAGE and LC-MS/MS to find that M. amurensis lectins can be divided into two groups. MASL is a member of one group which is composed of subunits that form dimers, evidently mediated by a cysteine residue in the carboxy region of the protein. In contrast to MASL, members of the other group do not dimerize under nonreducing conditions. These data also indicate that MASL is composed of 4 isoforms with an identical amino acid sequence, but unique glycosylation sites. We also produced a novel recombinant soluble human PDPN receptor (shPDPN) with 17 threonine residues glycosylated with sialic acid moieties with potential to act as a ligand trap that inhibits OSCC cell growth and motility. In addition, we report here that MASL targets PDPN with very strong binding kinetics in the nanomolar range. Moreover, we confirm that MASL can inhibit the growth and motility of human oral squamous cell carcinoma (OSCC) cells that express the PDPN receptor. Taken together, these data characterize M. amurensis lectins into two major groups based on their intrinsic properties, clarify the composition of MASL and its subunit isoform sequence and glycosylation sites, define sialic acid modifications on the PDPN receptor and its ability to act as a ligand trap, quantitate MASL binding to PDPN with KD in the nanomolar range, and verify the ability of MASL to serve as a potential anticancer agent.

RESUMO

Radiation treatment plays a mainstream role in the management of head and neck squamous cell carcinomas (HNSCCs). Adverse effects from radiation therapy include osteoradionecrosis of the jaw, and rarely, pathologic fracture. Immune checkpoint inhibitors (ICI) such as pembrolizumab are of growing relevance to the management of metastatic and recurrent HNSCCs. Adverse impacts on bone secondary to medications such as pembrolizumab and nivolumab have been sporadically documented in the literature. The objective of this manuscript is to raise awareness of possible increase in risk for adverse jaw outcomes in patients with HNSCCs exposed to both radiation treatment to the jaws and ICI therapy. This manuscript documents adverse jaw outcomes including osteonecrosis and pathologic fracture of the mandible in two patients receiving pembrolizumab for management of HNSCC who had received prior radiation treatment. A potential link between immunotherapy and adverse jaw outcomes is consistent with the growing understanding of osteoimmunology, investigating the closely interrelated processes in bone remodeling and immune system function, in health and disease. It is important to ascertain if pembrolizumab poses an incremental risk for such outcomes, beyond the risk from prior radiation, for patients managed with radiation treatment and ICI therapy for HNSCC. The general dental practitioner may encounter such patients either in the context of facilitating dental clearance prior to initiation of chemotherapy, or rarely, with poorly explained jaw symptoms and must be alert to the possibility of occurrence of such adverse jaw events to facilitate timely diagnosis and optimal patient management.

RESUMO

Objective The Model for End-stage Liver Disease-Sodium (MELD-Na) score was designed for prognosis of chronic liver disease and has been predictive of outcomes in a variety of procedures. Few studies have investigated its utility in otolaryngology. This study uses the MELD-Na score to investigate the association between liver health and ventral skull base surgical complications. Methods The National Surgical Quality Improvement Program database was used to identify patients who underwent ventral skull base procedures between 2005 and 2015. Univariate and multivariate analyses were performed to investigate the association between elevated MELD-Na score and postoperative complications. Results We identified 1,077 patients undergoing ventral skull base surgery with laboratory values required to calculate the MELD-Na score. The mean age was 54.2 years. The mean MELD-Na score was 7.70 (standard deviation = 2.04). Univariate analysis showed that elevated MELD-Na score was significantly associated with increased age (58.6 vs 53.8 years) and male gender (70.8 vs 46.1%). Elevated MELD-Na score was associated with increased rates of postoperative acute renal failure, transfusion, septic shock, surgical complications, and extended length of hospital stay. On multivariate analysis, associations between elevated MELD-Na and increased risk of perioperative transfusions (odds ratio [OR], 1.62; 95% confidence interval [CI], 1.20-2.93; p = 0.007) and surgical complications (OR, 1.58; 95% CI, 1.25-2.35; p = 0.009) remained significant. Conclusions This analysis points to an association between liver health and postoperative complications in ventral skull base surgery. Future research investigating this association is warranted.

RESUMO

INTRODUCTION: To assess the association between time to surgery (TTS) and survival in sinonasal squamous cell carcinoma patients (SSCC). METHODS: We queried the 2004-2016 National Cancer Database for all cases of adult SSCC undergoing primary surgical treatment. Patients with missing TTS information were excluded. We conducted a multivariate analysis of patient demographic and clinicopathological characteristics' effect on overall survival (OS) using a Cox proportional hazards model enhanced with cubic spline non-linear approximation. Bootstrapping methods were utilized to detect the aggregate risk of TTS delay on patient OS. RESULTS: A total of 2,881 patients met the inclusion criteria. The majority of patients were male (63.5%), White (86.3%), and over the age of 60 (58.4%). Parametric cubic spline approximation Cox hazard model detected a non-linear association between patient OS and TTS below 30 days with the lowest risk occurring at 18 days and steadily increasing subsequently. To analyze the aggregate risk and identify the optimal TTS cut-off after 30 days of surgical delay, the cohort sample was bootstrapped and dichotomized. The largest increase in aggregated risk was identified at 59 days (Hazards Ratio [HR] = 1.006 [0.839-1.084], p = 0.003). 60 days were used as the optimal TTS cut-off for analyzing the survival rate using the Cox proportional hazard model. Undergoing surgery within 60 days translated to a 14.6% decreased chance of death (HR: 0.854 [0.83-0.96]). CONCLUSIONS: Increasing TTS is associated with worse overall survival in patients with SSCC. Our study suggests that surgery should be done within 60 days to achieve optimal survival results. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:3389-3395, 2023.

RESUMO

OBJECTIVE: We sought to investigate the utility of elective neck dissection (END) in clinically node-negative parotid malignancy through the evaluation of factors that are associated with receiving END and survival analysis of patients who received END. STUDY DESIGN: Retrospective cohort database study. SETTING: The National Cancer Database (NCDB). METHODS: The NCDB was used to extract patients with clinically node-negative parotid malignancy. END was defined as having 5 or more lymph nodes examined pathologically, as previously defined in the literature. Univariate and multivariate analyses were used to compare predictors of receiving END, rates of occult metastasis, and survival. RESULTS: Of the 9405 included patients, 3396 (36.1%) underwent an END. END was most frequently performed for squamous cell carcinoma (SCC) and salivary duct histology. All other histologies were significantly less likely to undergo END compared to SCC (p < .05). Salivary ductal carcinoma and adenocarcinoma had the greatest rates of occult node disease (39.8% and 30.0%, respectively), followed by SCC (29.8%). Kaplan-Meier survival analysis showed a statistically significant increase in 5-year overall survival in patients who received END with poorly differentiated mucoepidermoid (56.2% vs 48.5%, p = .004) along with moderately and poorly differentiated SCC (43.2% vs 34.9%, p = .002; 48.9% vs 36.2%, p < .001, respectively). CONCLUSION: Histological classification is a benchmark for determining which patients should receive an END. We demonstrated an increase in overall survival in patients who undergo END with poorly differentiated tumors of mucoepidermoid and SCC histology. As such, histology should be considered along with clinical T-stage and rate of occult nodal metastasis to determine eligibility for END.

RESUMO

BACKGROUND: Preoperative laboratory tests (PLTs) are often obtained prior to outpatient surgical procedures. The objective of this study is to examine the current practice of routine PLT in low-risk patients undergoing ambulatory endoscopic sinonasal surgery (ESS) and to assess whether such testing impacts surgical outcomes. METHODS: Patients undergoing ambulatory ESS were identified from the 2011 to 2018 NSQIP database. Low-risk patients were defined as American Society of Anesthesiologist class 1 or 2. PLTs were grouped into hematologic, chemistry, coagulation, and liver function tests. Chi-square analyses and independent samples t-tests were conducted to compare categoric and continuous variables, respectively. RESULTS: A total of 664 cases met the inclusion criteria, of which 419 (62.1%) underwent at least one PLT. Of these, the most frequent PLT obtained was a complete blood cell count (92.4%). Major complications occurred in 1.5% of patients. There were no statistically significant differences in overall postoperative complications between those with and without PLT (P = .264). Specifically, no significant difference was seen in the incidence of postoperative bleeding (P = .184), urinary tract infection (P = .444), pulmonary embolism (P = .444), or wound infection (P = .701). On multivariable analyses, PLT status was not significantly associated with any complication (P = .097) or unplanned readmission (P = .898). CONCLUSIONS: Our analysis did not reveal an association between the use of PLT and postoperative morbidity or unplanned readmission in low-risk patients undergoing outpatient ESS.

RESUMO

OBJECTIVE: Kaposi sarcoma (KS) of the larynx is a rare disease with few cases reported in the literature. This study aims to provide a comprehensive review of laryngeal KS, including patient characteristics, treatment, and clinical outcomes. DATA SOURCES: PubMed, CINAHL, SCOPUS, and Cochrane Library. REVIEW METHODS: A systematic review of the published English literature was conducted. An electronic search and bibliographic examination of articles pertaining to laryngeal KS were performed. Demographic data, tumor site, treatment strategies, follow-up, and outcome were analyzed. RESULTS: A total 77 cases from 50 articles were included in the review. The mean age was 47.6 years (range, 8-81). There was an 8.6:1 male:female ratio. The most common presenting symptoms were dyspnea (n = 35) and hoarseness (n = 25). Laryngeal KS arose most frequently in the supraglottic region (n = 16). Chemotherapy alone (n = 27) was the most common treatment modality in patients with AIDS-associated KS, and surgical excision alone (n = 7) was most common in patients with other subtypes of KS (eg, classic, transplant associated). Average follow-up was 20.4 months (range, 0.75-120). Most patients with AIDS-associated KS died of other causes (n = 25), but most patients with other subtypes of KS were alive with no evidence of disease at follow-up (n = 13). CONCLUSION: This review contains the largest pool of laryngeal KS cases to date. Long-term outcomes were generally unfavorable, often due to advanced HIV disease at the time of diagnosis.

RESUMO

OBJECTIVE: To determine how prolonged operative time (POT) impacts 30-day outcomes in patients undergoing endoscopic sinonasal surgery (ESNS). STUDY DESIGN: Retrospective study. METHODS: Data from patients who underwent ESNS (nonsinus, sinus, and extended sinus) between 2005 to 2018 were collected from the American College of Surgeons National Surgical Quality Improvement database. Univariate and multivariate analyses were performed to evaluate the effect of POT on postoperative outcomes. RESULTS: Among 1,994 ESNS cases, 495 nonsinus procedures, 1,191 sinus procedures, and 308 extended sinus procedures were identified. Median OT was 90 minutes (interquartile range [IQR], 51-165 minutes) for nonsinus procedures, 113 minutes (IQR, 66-189 minutes) for sinus procedures, and 187 minutes (IQR, 137-251 minutes) for extended sinus procedures. Other than older age (P = .008), POT was not significantly associated with baseline demographics and comorbidities for patients undergoing non-sinus procedures. Older age (P < .001), White and Black race (P < .001), ASA physical classifications III or IV (P < .001), and several preoperative comorbidities, including obesity (P = .045), and hypertension (P < .001) were associated with POT for sinus procedures. Older age (P = .030), male sex (P = .010), and lower body mass index (P = .004) were associated with POT for extended sinus procedures. After risk-adjustment, POT was independently associated with prolonged hospital stay (LOS) for all procedure categories, and associated with overall surgical complications and postoperative bleeding for sinus and extended sinus procedures specifically. CONCLUSION: POT is independently associated with several adverse outcomes following ESNS, including prolonged LOS, overall surgical complications, and bleeding. Preoperative planning should include optimizing modifiable patient risk factors for POT and identifying surgeon-specific factors to enhance surgical efficiency.

RESUMO

OBJECTIVE: Tuberculous otitis media (TOM) is a rare extrapulmonary manifestation of tuberculosis (TB) and remains challenging to diagnose due to non-specific symptoms. This systematic review identifies clinical characteristics, diagnostic evaluation, and outcomes in cases of TOM. METHODS: A comprehensive literature search utilizing the PubMed, CINAHL, Scopus, and Cochrane Library databases was conducted for relevant articles published between 2000 and 2021. Cases involving adult patients with TOM were included. Non-English studies, animal studies, and reviews were excluded. RESULTS: 41 case reports and 7 case series were included, comprising data from 67 patients. The mean age was 40 years (range, 19-87 years) and the majority were female (n = 46, 68.7 %). The mean symptom duration was 12.8 months (range, 0.25-120 months). Common symptoms included otorrhea (n = 60, 89.6 %), HL (n = 58, 86.6 %), otalgia (n = 19, 28.4 %), and FP (n = 18, 26.9 %). Otoscopy revealed tympanic membrane (TM) perforation in 45 patients (67.2 %). Most patients were diagnosed with tissue biopsy (n = 53, 79.1 %). Surgical interventions were performed in 48 patients (71.6 %) and 63 patients (94.0 %) were prescribed anti-TB chemotherapy. Long-term sequelae (e.g., HL, FP, and TM perforation) were noted in 39 patients (58.2 %) at a mean follow-up of 18.8 months (range, 1-120 months). CONCLUSION: TOM should be included in the differential diagnosis of chronic suppurative otitis media. Histopathological examination is a reliable diagnostic method. Early detection and management are recommended for optimizing outcomes. LEVEL OF EVIDENCE: 3b.

RESUMO

BACKGROUND: While extramedullary plasmacytomas are infrequently encountered plasma cell malignancies, most cases occur in the head and neck, with a predilection for the sinonasal cavity. Due to the rarity of this disease, the majority of studies on sinonasal extramedullary plasmacytoma (SN-EMP) are case reports or small retrospective case series. OBJECTIVE: To investigate the impact of patient, disease, and treatment factors on the survival of patients with SN-EMP. METHODS: The National Cancer Database was queried for all patients with SN-EMP between 2004-2016 (N = 381 cases). Univariate and multivariate analyses were used to examine patient demographics, tumor characteristics, and survival. RESULTS: The majority of SN-EMP patients were over 60 years old (57.0%), male (69.8%), and white (86.2%). The most common treatment modality was radiotherapy alone (38.6%), followed by surgery plus radiotherapy (37.8%). Five-year overall survival was 74.0% and median survival was 9.1 years. Accounting for patient demographics and tumor characteristics in a multivariate model, the following groups had worse prognosis: 60 and older (HR 1.99, p = 0.031) and frontal sinus primary site (HR 11.56, p = 0.001). Patients who received no treatment (HR 3.89, p = 0.013), chemotherapy alone (HR 5.57, p = 0.008) or radiotherapy plus chemotherapy (HR 2.82, p = 0.005) had significantly lower survival than patients who received radiotherapy alone. Patients who received surgery with radiotherapy (HR 0.57, p = 0.039) had significantly higher survival than patients who received radiotherapy alone. CONCLUSION: In patients with SN-EMP five-year overall survival was found to be 74.0% with decreased survival associated with a frontal sinus primary site and being aged 60 or older. Patients receiving no treatment, chemotherapy alone, or radiotherapy with chemotherapy was associated with lower survival. Receiving surgery plus radiotherapy was associated with the highest five-year overall survival.

RESUMO

OBJECTIVE: This study aims to provide an age-stratified analysis of associations with patient sex in pediatric inpatients with acute rhinosinusitis (ARS). STUDY DESIGN: Retrospective cohort study. SETTING: National administrative database. METHODS: The 2016 Kids' Inpatient Database was queried for pediatric inpatients (<21 years old) with ARS (ICD-10 J01). Orbital and intracranial sequelae were selected via ICD-10 codes. Statistical associations by sex were determined via univariate and multivariable analyses. Weighted measures are reported to provide national estimates. RESULTS: Of the 5882 patients identified with ARS, 2404 (40.9%) were female and 3478 (59.1%) were male. Male patients were younger than female patients (mean, 9.3 vs 9.9 years; P < .001). Multivariable analysis indicated that males and females had similar total charges ($71,094 vs $66,892, P = .464) and length of stay (5.8 vs 6.1 days, P = .263). However, male patients underwent more procedures (1.8 vs 1.5, P < .001). Mortality was similar between male and female patients (odds ratio [OR], 0.91; P = .664). Male patients also had increased odds for having orbital (OR, 1.58; P < .001) and intracranial (OR, 1.99; P < .001) complications. Differences in sex-dependent sequela risk were starkest in patients aged 14 to 20 years, with male patients being more likely to have orbital (OR, 2.91; P < .001) and intracranial (OR, 3.86; P < .001) complications. CONCLUSION: In a cohort of pediatric inpatients with ARS, males have increased odds for orbital and intracranial sequelae and undergo more procedures than females. However, males and females have similar charges and length of stay. Our study highlights age-stratified differences in ARS across patient sex.

RESUMO

OBJECTIVES/HYPOTHESIS: Preoperative anemia has been shown to be a predictor of complications in different surgeries. This has not been exclusively studied in skull base surgery. This study investigates the impact of preoperative hematocrit on complications following ventral skull base (VSB) surgery. STUDY DESIGN: Retrospective database review. METHODS: The National Surgical Quality Improvement Program was queried for all cases of VSB surgery from 2005 to 2015. Univariate and multivariate analyses were performed to investigate the impact of preoperative anemia on complications following VSB procedures. RESULTS: 3,053 patients meeting inclusion criteria were identified. On univariate analysis, low hematocrit was found in 39.7% of patients and was associated with increased mean age (55.71 vs. 53.25 years), male gender (63.6% vs. 36.4%), and Black race (18.5% vs. 10.9%). Preoperative anemia was also associated with increased incidences of postoperative pneumonia, blood transfusions, sepsis, medical complications, surgical complications, extended length of hospital stay (LOS), and mortality. On multivariate analysis, associations between low preoperative hematocrit and perioperative transfusions (odds ratio [OR] 2.57, 95% confidence interval [CI] 1.88-3.50, P < .001), total surgical complications (OR 2.12, 95% CI 1.60-2.80, P < .001), and extended LOS (OR 1.29, 95% CI 1.05-1.57, P = .013) remained significant. CONCLUSIONS: Low preoperative hematocrit is associated with increased risk of postoperative complications and extended LOS in patients undergoing VSB surgery. This study highlights the importance of careful preoperative assessment and management of anemia in these patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:1707-1713, 2022.

RESUMO

OBJECTIVE: To analyze population-level data for Burkitt's lymphoma of the head and neck. STUDY DESIGN: Retrospective study of a national cancer database. SETTING: Academic medical center. METHODS: The SEER database (Surveillance, Epidemiology, and End Results) identified all patients with primary Burkitt's lymphoma of the head and neck from 1975 to 2015. Demographic, clinicopathologic, and treatment characteristics were analyzed. Multivariable Cox regressions analyzed factors associated with survival while controlling for baseline differences. RESULTS: A total of 920 patients with a mean (SD) age of 37.6 years (25.0) were identified. A majority of patients were White (82.8%) and male (72.3%). The most primary common sites included the lymph nodes (61.3%), pharynx (17.7%), and nasal cavity/paranasal sinuses (5.2%). The majority of patients received chemotherapy (90.5%), while fewer underwent surgery (42.1%) or radiotherapy (12.8%). Choice of treatment differed significantly among patients of different ages, year of diagnosis, primary site, nodal status, and Ann Arbor stage. Overall 10-year survival was 67.8%. On multivariable Cox regression, patients with older age (hazard ratio [HR], 1.05 per year; P < .001) and higher stage at presentation had increased risk of mortality (P < .001). Furthermore, cases diagnosed between 2006 and 2015 (HR, 0.35; P < .001) and 1996 and 2005 (HR, 0.53; P = .001) had lower mortality when compared with those diagnosed between 1975 and 1995. Treatment including surgery and chemotherapy tended to have the best survival (P < .001). CONCLUSION: Burkitt's lymphoma of the head and neck diagnosed in more recent years has had improved survival. Factors significantly associated with survival include age, Ann Arbor stage, and treatment regimen. Treatment including surgery and chemotherapy was associated with the highest survival.

RESUMO

OBJECTIVES: The purpose of this study is to compare the number of citations received by open access articles versus subscription access articles in subscription journals in the Otolaryngology literature. METHODS: Using the Dimensions research database, we examined articles indexed to PubMed with at least 5 citations published in 2018. Articles were included from Otolaryngology-Head and Neck Surgery, The Laryngoscope, JAMA Otolaryngology-Head and Neck Surgery, Annals of Otology, Rhinology, and Laryngology, and American Journal of Otolaryngology. Multivariate Poisson regression modeling was used to adjust for journal, article type, and topic. Practice guidelines, position statements, or retractions were excluded as potential outliers. RESULTS: 137 open access articles and 337 subscription access articles meeting inclusion criteria were identified, with a median citation number of 8 (IQR 6-11). The most common article type was original investigation (82.5%), and the most common study topic was head and neck (28.9%). Open access articles had a higher median number of citations at 9 (IQR 6-13) when compared to subscription access articles at 7 (IQR 6-10) (P = .032). Open access status was significantly associated with a higher number of citations than subscription access articles when adjusting for journal, article type, and topic (ß = .272, CI 0.194-0.500, P < .001). CONCLUSIONS: Although comprising a minority of articles examined in this study of subscription journals, open access articles were associated with a higher number of citations than subscription access articles. Open access publishing may facilitate the spread of novel findings in Otolaryngology.

RESUMO

OBJECTIVE: To investigate the demographics of CORE grant recipients (Centralized Otolaryngology Research Efforts) over the last decade and evaluate disparity among recipients as compared with otolaryngology overall. To assess whether procurement of a grant predicts pursuit of an academic career. STUDY DESIGN: Analysis of grant recipients' bibliometrics. SETTING: Academic medical center. METHODS: The list of recipients of grants from 2010 to 2019 was obtained from the website of the American Academy of Otolaryngology-Head and Neck Surgery. Demographics of recipients were collected through an internet search, including gender, race, residency program, and h-index. Recipients from 2010 were searched to determine current academic faculty rank. Univariate and multivariate analyses were used to compare these factors with otolaryngology overall. RESULTS: The distribution of gender among recipients over the last decade remained nearly constant, with no significant difference versus residents in otolaryngology (P > .05). However, there were significantly more female recipients when adjusted for gender differences in the field overall (P < .01). Asians were relatively overrepresented, while Black and Hispanic residents were underrepresented (P < .01). Many recipients (52.6%) trained at institutions recognized as the best training programs with reputations for quality research output. The h-index of recipients decreased over the last decade (P < .01). The h-index of duplicate winners was significantly higher than those of nonduplicate winners (P < .01). After adjusting for gender and rank, recipients were significantly more likely to hold academic positions (P < .01). CONCLUSION: CORE grants are favorably distributed as related to gender and racial disparities, and recipients frequently go on to achieve high levels of academic success.

RESUMO

OBJECTIVES/HYPOTHESIS: To identify factors that may increase the risk of unplanned admission following elective outpatient endoscopic sinonasal surgery (ESS). STUDY DESIGN: Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP). METHODS: All cases of ESS were extracted from the 2010 to 2018 NSQIP database using Current Procedural Terminology codes. Only cases coded as outpatient, elective, and nonemergent procedures were included. Unplanned admissions were defined as cases with a total hospital stay of 1 day or more. Univariate and multivariate analyses were performed to identify variables that independently predicted unanticipated admission. RESULTS: A total of 971 cases met inclusion criteria, of which 274 (28.2%) were unanticipated admissions. Patients in the unplanned admission group were more likely to be older (46.8 vs. 41.1 years, P < .001), male (57.7% vs. 48.4%, P = .009), obese (54.8% vs. 43.8%, P = .003), and have hypertension (35.0% vs. 25.0%, P = .002). Unplanned admitted patients were also more likely to be included under American Society of Anesthesiologists (ASA) classification III-IV (43.1% vs. 27.2%, P < .001). There were no significant differences in race, smoking, diabetes, or chronic steroid use. Unplanned admitted patients had a higher rate of surgical complications (2.9% vs. 1.0%, P = .041). Upon multivariate analysis, independent preoperative risk factors for unplanned admission included age (OR: 1.018, P = .002), male gender (OR: 1.415, P = .025), obesity (OR: 1.527, P = .008), and ASA III-IV (OR 1.501, P = .018). CONCLUSIONS: Factors independently associated with unplanned admission following outpatient ESS were older age, male gender, obesity, and higher ASA. Identification of patients at risk may reduce unanticipated hospital admission after ESS. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:518-522, 2022.

RESUMO

BACKGROUND: To investigate the association between American Society of Anesthesiologists (ASA) physical status classification and rates of postoperative complications in patients undergoing facial fracture repair. METHODS: Patients were divided into 2 cohorts based on the ASA classification system: Class I/II and Class III/IV. Chi-square and Fisher's exact tests were used for univariate analyses. Multivariate logistic regressions were used to assess the independent associations of covariates on postoperative complication rates. RESULTS: A total of 3575 patients who underwent facial fracture repair with known ASA classification were identified. Class III/IV patients had higher rates of deep surgical site infection (P = .012) as well as bleeding, readmission, reoperation, surgical, medical, and overall postoperative complications (P < .001). Multivariate regression analysis found that Class III/IV was significantly associated with increased length of stay (P < .001) and risk of overall complications (P = .032). Specifically, ASA Class III/IV was associated with increased rates of deep surgical site infection (P = .049), postoperative bleeding (P = .036), and failure to wean off ventilator (P = .027). CONCLUSIONS: Higher ASA class is associated with increased length of hospital stay and odds of deep surgical site infection, bleeding, and failure to wean off of ventilator following facial fracture repair. Surgeons should be aware of the increased risk for postoperative complications when performing facial fracture repair in patients with high ASA classification.

RESUMO

BACKGROUND: Using a population-based database, this study investigates the risk factors, epidemiology, and outcomes of basal cell adenocarcinoma (BCAC) of the head and neck. METHODS: The Surveillance, Epidemiology, and End Results database was analyzed for all patients with BCAC of the head and neck from 1973 to 2015. RESULTS: Three hundred and twenty-two cases of BCAC of the head and neck were identified. Mean age of diagnosis was 64.1 years. 52.5% were male and 77.3% were white. The most common primary site was the parotid gland (71.7%). Most patients underwent surgery alone (51.9%). Five-year disease-specific survival (5Y-DSS) was 95.6%, and 10Y-DSS was 90.3%. Highest survival was seen with surgery alone followed by combined surgery and radiation (10Y-DSS: 93.9% vs. 88.9%, p = 0.001). Age, primary site, T-classification, grade, and treatment type significantly affected survival. CONCLUSIONS: BCAC of the head and neck presents most frequently in the parotid glands. Surgery alone is associated with highest survival.

RESUMO

OBJECTIVE: The objective of this study was to analyze national trends in human papillomavirus (HPV) testing for patients diagnosed with sinonasal squamous cell carcinoma (SNSCC). STUDY DESIGN: Retrospective database study. SETTING: National Cancer Database (2010-2016). METHODS: Cases from 2010 to 2016 with a primary SNSCC diagnosis and known HPV testing status were extracted from the National Cancer Database. Univariate and multivariate analyses were then performed to assess differences in socioeconomic, hospital, and tumor characteristics between tested and nontested patients. RESULTS: A total of 2308 SNSCC cases were collected, with 1210 (52.4%) HPV tested and 1098 (47.6%) not tested. On univariate analyses, patient age, insurance, income quartile, population density, treatment facility location, and tumor grade were significantly associated with HPV testing status. After multivariate logistic regression modeling, living in a suburban area had lower odds of HPV testing as compared with living in urban areas (odds ratio, 0.74 [95% CI, 0.55-0.99]; P = .041), while tumor grade III/IV had higher odds than grade I (odds ratio, 1.73 [95% CI, 1.29-2.33]; P < .001). HPV-tested patients had a similar 5-year overall survival to nontested patients (48.3% vs 45.3%, log-rank P = .405). A sharp increase in HPV testing rates was observed after 2010 (P < .001). CONCLUSION: Among patients with SNSCC, those with high-grade tumors were more likely to be tested for HPV, while patients with a suburban area of residence were less likely. Additionally, there was no significant survival benefit to HPV testing, with tested and nontested groups having similar overall survival. LEVEL OF EVIDENCE: 4.
