Photoangiolytic Lasers for Treatment of Benign Laryngeal Lesions: A Systematic Review and Meta-Analysis.

OBJECTIVES: To compare the efficacy of the 445-nm blue laser to the 585-nm pulsed dye laser (PDL) and 532-nm potassium-titanyl-phosphate (KTP) laser in the treatment of benign laryngeal lesions. DATA SOURCES: Cochrane Library, PubMed, Scopus, and CINAHL. REVIEW METHODS: Following PRISMA guidelines, databases were searched from inception through January 29, 2024, for studies reporting the use of photoangiolytic lasers for treatment of benign laryngeal lesions, including the 585-nm PDL, 532-nm KTP laser, and 445-nm blue laser. Outcome measures included lesion resolution (%), mean differences (Δ) in Voice Handicap Index (VHI-10), and summed dysphonia grade, roughness, and breathiness (GRB) scale. RESULTS: A total of 45 studies were included for meta-analysis, consisting of 348 patients treated with PDL, 550 patients with KTP laser, and 338 patients with blue laser. Treatment with blue laser resulted in the greatest lesion resolution (94.0%; 95% confidence interval [CI]: 90.2%-96.7%), followed by KTP laser (90.4%; 95% CI: 84.1%-95.2%), and PDL (86.9%; 95% CI: 62.9%-99.2%). VHI-10 improved significantly in patients following treatment with blue laser (Δ13.3; 95% CI: 10.7-16.0; p < 0.0001), KTP laser (Δ10.3; 95% CI: 7.4-13.3; p < 0.0001), and PDL (Δ7.4; 95% CI: 4.8-10.1; p < 0.0001). GRB improved significantly in patients following treatment with blue laser (Δ4.1; 95% CI: 2.9-5.2; p < 0.0001), KTP laser (Δ3.0; 95% CI: 2.0-4.0; p < 0.0001), and PDL (Δ2.5; 95% CI: 0.8-4.2; p = 0.005). CONCLUSIONS: Photoangiolytic lasers are effective in treating benign laryngeal lesions. Blue lasers are promising for laryngeal laser surgery. Laryngoscope, 2024.

Sex and human papillomavirus in oropharyngeal cancer: A systematic review and meta-analysis.

INTRODUCTION: While the presence of human papillomavirus (HPV) is known to affect the outcomes of oropharyngeal squamous cell carcinoma (OPSCC), there is a significant gap in research regarding the potential sex-based differences. This systematic review-metanalysis (SR-MA) aims to evaluate if sex is a prognostic factor in HPV-associated OPSCC. METHODS: A systematic review and meta-analysis was performed. COCHRANE Library, CINAHL, PubMed, and Scopus were searched for English-language articles from 1966 to October 2023. Studies with multivariable analysis of overall survival (OS) based on sex were included. Adjusted hazard ratios (aHRs) with a 95 % confidence interval (CI) were presented for the reported outcome. A meta-analysis of single means, proportions, and aHRs with a 95 % CI was conducted. RESULTS: This SR-MA included 24 studies (n = 101,574). The proportion of female patients was 16.6 % [15.4 %-17.8 %]. A meta-analysis of all included studies with OS showed no significant difference in survival between male and female patients. In US-based studies, no significant difference in OS is observed between male and female patients. International studies reported a better OS for female patients (aHR = 0.68, 95 % CI, 0.48-0.95). CONCLUSION: This meta-analysis suggests that sex does not represent a significant prognostic factor for patients affected by HPV associated OPSCC. When stratified by geographic location, findings suggests that female patients from the US with HPV OPSCC have similar OS than male patients but in international studies it suggests male patients have worse OS.

Audiovestibular outcomes in adult patients with cogan syndrome: a systematic review.

PURPOSE: To determine factors associated with steroid responsiveness and efficacy of biologic disease-modifying anti-rheumatic (DMARD) use in patients with Cogan Syndrome (CS). METHODS: A systematic search of Cochrane Library, PubMed, CINAHL, and Scopus was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Any study describing audiometric or vestibular data and pharmacologic treatment in patients with CS was included. Due to limited literature, only case reports/case series were included. RESULTS: Seventy case reports or case series studies comprising 79 individual cases of CS were included. A difference in vestibular symptoms with a higher prevalence in the steroid-resistant group than the steroid-responsive group was found (79.5% vs 57.9%, p = 0.04). Eighteen (60.0%) patients treated only with oral steroids had no audiological improvement, while twelve (n = 12; 85.7%) patients treated with biologic DMARD showed audiological improvement. The steroid-responsive group had an overall better response to DMARDs than the steroid-resistant group (62.1% vs 45.0%; 100.0% vs 77.8%). CONCLUSIONS: Our study synthesized the available literature to better characterize steroid resistance in patients with Cogan syndrome and treatment outcomes. Vestibular symptoms were noted to be more prevalent in patients who were eventually labeled as steroid resistant. There were higher rates of audiological improvement in patients given biologic DMARDs rather than conventional DMARDs or steroids only. Further studies are needed to characterize each individual vestibular symptom and investigate the utility and timing of biologic DMARDs in managing patients with Cogan syndrome.

The placebo effect of sham rhinologic procedures in randomized controlled trials: A systematic review and meta-analysis.

KEY POINTS: Sham procedures produce a clinically significant impact on patient-reported outcome measures This effect should be considered when designing and interpreting the results of RCTs.

Charcot-Marie-Tooth Disease and Hearing Loss: A Systematic Review With Meta-Analysis.

OBJECTIVE: To characterize the pattern of hearing loss in Charcot-Marie-Tooth (CMT) disease to help guide clinical management. DATABASES REVIEWED: CINAHL, PubMed, and Scopus. METHODS: Two independent investigators selected studies on CMT patients with pure-tone average (PTA) and auditory brainstem response (ABR) data. Case reports, case series <5 patients, and data that overlapped with another study were excluded. Investigators performed data extraction, quality rating, and risk-of-bias assessment using the Newcastle-Ottawa Scale. Meta-analysis of mean difference using fixed/random effects models was used. Also, data were analyzed using a weighted one-way analysis of variance, with post-hoc Tukey's test for comparison. RESULTS: Ultimately, 6 prospective studies (N = 197) were included. The most common demyelinating subtype (CMT1A) had significantly prolonged ABR latency values across wave III (0.20 ms, 95% confidence interval [CI]: 0.05-0.35), wave V (0.20 ms, 95% CI: 0.01-0.39), waves I-III (0.20 ms, 95% CI: 0.01-0.39), and waves I-V (0.20 ms, 95% CI: 0.01-0.39) when compared to matched controls. The autosomal recessive demyelinating subtype (CMT4C) had significantly worse PTA when compared to the most common subtype (CMT1A) (Δ 28.93 dB, 95% CI 18.34-39.52) and nondemyelinating subtype (CMT2A) (Δ 28.3 dB, 95% CI: 15.98-40.62). CONCLUSIONS: Patients with CMT can present with a variety of phenotypes depending on the causative mutation. The ABR interpeak latency values for the most common demyelinating form of CMT are delayed when compared to matched controls. Most subtypes have normal hearing thresholds, apart from CMT4C, which presents with mild hearing loss on average.

Dexmedetomidine and surgical field visibility in nasal surgery: A systematic review and meta-analysis.

INTRODUCTION: Nasal and sinus surgery, especially using endoscopy, relies upon adequate haemostasis to be safe and effective. Often other haemostatic methods, such as cautery are not viable, and other methods must be employed. This study examines the effectiveness of dexmedetomidine in controlled hypotension and for surgical field visibility in endoscopic sinus surgery and other nasal surgeries. REVIEW METHODS: A literature search was conducted in PubMed, Scopus, CINAHL and Central for randomised controlled trials using dexmedetomidine for controlled hypotension in adult patients undergoing endoscopic sinus surgery or other nasal surgery. Meta-analysis of mean differences and single means were performed. RESULTS: Of 935 identified studies, 31 met the inclusion criteria. A statistically significant difference in Fromme-Boezaart surgical field visibility scores was found comparing dexmedetomidine to placebo (p < 0.00001) and propofol (p < 0.0001), but not other agents. A significant difference in intraoperative blood loss volume was found compared with placebo (51.5mL, p < 0.00001) and propofol (13.6mL, p < 0.0001), but not other agents. CONCLUSION: Dexmedetomidine demonstrated significantly improved surgical field visibility and blood loss volume compared with placebo and propofol, but not other agents. Dexmedetomidine is viable and useful for controlled hypotension in nasal surgery. Choice of controlled hypotension agent should follow patient and procedure-specific considerations.

Exploring Side Effects of Sublingual Immunotherapy: A Systemic Review and Meta-Analysis.

Objective: Sublingual immunotherapy (SLIT) has emerged as a potentially safe and convenient option for allergen immunotherapy for patients with inhalant allergy. Larger studies on the overall side effects and severe reactions anaphylaxis are still lacking. Study Design: Systematic review and meta-analysis. Setting: Author's review was completed in the University of Texas Medical Branch. Methods: A systematic review and meta-analysis of prospective clinical trials focusing on SLIT safety published from January 1, 2001, to December 31, 2021, was conducted. Results: Twenty-six studies were included with analysis of 7827 patients, representing over 2.7 million SLIT doses. All studies focused on single-antigen immunotherapy. The mean duration of treatment was 11.54 months. Local side effects were present in 40.83% of patients [95% confidence interval (CI) 24.78-57.96]. Systemic side effects were encountered in 1.09% of SLIT patients (95% CI 0.57-1.78). Anaphylaxis was reported in 0.13% of patients (95% CI 0.06-0.22). Discontinuation rates due to side effects were low, at 4.32% of patients (95% CI 3.28-5.49). Conclusion: This meta-analysis shows that single-antigen SLIT is well-tolerated, with overall low rates of systemic side effects including anaphylaxis. Although there is a high rate of minor local side effect, the treatment attrition during the first year is low. With growing allergy burden worldwide, SLIT is a convenient and economically feasible option for immunotherapy. Further work is needed to evaluate long-term safety and efficacy of single as well as multi-antigen SLIT, including quality of life assessments.

Factors Associated with Head and Neck Cancer Postoperative Radiotherapy Delays: A Systematic Review and Meta-analysis.

OBJECTIVE: Initiating postoperative radiotherapy (PORT) within 6 weeks of surgery for head and neck squamous cell carcinoma (HNSCC) is included in the National Comprehensive Cancer Network Clincal Practice Guidelines and is a Commission on Cancer quality metric. Factors associated with delays in starting PORT have not been systematically described nor synthesized. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: We included studies describing demographic characteristics, clinical factors, or social determinants of health associated with PORT delay (>6 weeks) in patients with HNSCC treated in the United States after 2003. Meta-analysis of odds ratios (ORs) was performed on nonoverlapping datasets. RESULTS: Of 716 unique abstracts reviewed, 21 studies were included in the systematic review and 15 in the meta-analysis. Study sample size ranged from 19 to 60,776 patients. In the meta-analysis, factors associated with PORT delay included black race (OR, 1.46, 95% confidence interval [CI]: 1.28-1.67), Hispanic ethnicity (OR, 1.37, 95% CI, 1.17-1.60), Medicaid or no health insurance (OR, 2.01, 95% CI, 1.90-2.13), lower income (OR, 1.38, 95% CI, 1.20-1.59), postoperative admission >7 days (OR, 2.92, 95% CI, 2.31-3.67), and 30-day hospital readmission (OR, 1.37, 95% CI, 1.29-1.47). CONCLUSION: Patients at greatest risk for a delay in initiating guideline-adherent PORT include those who are from minoritized communities, of lower socioeconomic status, and experience postoperative challenges. These findings provide the foundational evidence needed to deliver targeted interventions to enhance equity and quality in HNSCC care delivery.

Headache and Facial Pain/Pressure in the Chronic Rhinosinusitis Population: A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate the severity and prevalence of headache and facial pain/pressurere in the chronic rhinosinusitis (CRS) population. DATA SOURCES: CINAHL, PubMed, Scopus. REVIEW METHODS: The literature was searched from inception through June 2023 for English language articles documenting "headache" or "facial pain/pressure" and "chronic rhinosinusitis." Data collected included Lund-MacKay computed tomography score, Lund-Kennedy endoscopy score, sinonasal outcome test, and visual analog scale. Meta-analyses were performed on continuous measures (mean), proportions (%), and regression. RESULTS: A total of 69 studies were included with 8643 CRS patients and 703 control patients. The CRS group had a mean age of 44.1 (range: 16-82; 95% confidence interval [CI]: 40.3-48) and 86.1% [95% CI: 76.4-93.5] with nasal polyposis. The control group had a mean age of 39.2 (range: 17-88; 95% CI: 28.7-49.8). All CRS subgroups had significantly more severe headache and facial pain/pressure when compared to the control (P < .0001). Patients without polyps had significantly more severe facial pain/pressure and headache when compared to patients with polyps (P < .0001). Facial pain/pressure is a moderate problem or worse in 29.8% of polypoid patients versus 56.4% of nonpolypoid patients; Δ26.6% [95% CI: 0.7-50; P = .045]. CONCLUSIONS: Across all outcome metrics, CRS patients experience significantly more severe headache and facial pain/pressure when compared to a control population. Nonpolypoid patients experience significantly more severe facial pain/pressure and headache when compared to polypoid patients. The majority of nonpolypoid patients experience facial pain/pressure that is moderate in severity or worse.

Surgical outcomes and revision rates for velopharyngeal insufficiency (VPI) in syndromic and non-syndromic children: A systematic review and meta-analysis.

PURPOSE: To evaluate pre- and post-operative resonance, surgical technique, revision rate, and revision indication among syndromic and non-syndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: A systematic review was conducted through July 2022. Children surgically treated for VPI were included. A meta-analysis of single means, proportions, comparison of proportions, and mean differences with 95 % confidence interval [CI] was conducted. RESULTS: Twenty-three articles (n = 1437) were included in the analysis. The most common surgery was Sphincter Pharyngoplasty (SP), 62.6 % [31.3-88.9] for syndromic and 76.3 % [37.5-98.9] for non-syndromic children. Among all surgical techniques, for syndromic and non-syndromic children, 54.8 % [30.9-77.5] and 73.9 % [61.3-84.6] obtained normal resonance post-operatively, respectively. Syndromic patients obtained normal resonance post-operatively in 83.3 % [57.7-96.6] of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty (CPSP), 72.6 % [54.5-87.5] of Pharyngeal Flap (PF), and 45.1 % [13.2-79.8] of Sphincter Pharyngoplasty (SP) surgeries. Non-syndromic patients obtained normal resonance post-operatively in 79.2 % [66.4-88.8] of PF and 75.2 % [61.8-86.5] of SP surgeries. The revision rate for syndromic and non-syndromic patients was 19.9 % [15.0-25.6] and 11.3 % [5.8-18.3], respectively. The difference was statistically significant, 8.6 % [2.9-15.0, p = 0.003]. Syndromic patients who underwent PF were least likely to undergo revision surgery as compared to SP and CPSP, 7.7 % [2.3-17.9] vs. 23.7 % [15.5-33.1] and 15.3 % [2.8-40.7], respectively. CONCLUSIONS: Syndromic children had higher revision rates and were significantly less likely to obtain normal resonance following primary surgery than non-syndromic patients. Among syndromic children, PF and CPSP have been shown to improve resonance and reduce revision rates more so than SP alone.

Topical steroids for chronic rhinosinusitis without nasal polyps: A systematic review and meta-analysis.

BACKGROUND: Evidence supporting topical steroids for the treatment of chronic rhinosinusitis without nasal polyposis (CRSsNP) is unclear. Recent trials describe alternative topical steroid delivery modalities, including rinses and exhalation delivery system (EDS), necessitating a re-examination of the current literature. METHODS: Cochrane Library, CINAHL, PubMed, and Scopus databases were searched from inception to February 13, 2024 for placebo-controlled randomized control trials on topical steroids used to treat CRSsNP, including topical spray, nasal irrigation, sinonasal catheter, and EDS modalities. Primary outcome measures included total symptom scores (TSS) (Δ) and response rates (odds ratio). RESULTS: Ten trials (N = 751) were included for meta-analysis, with a mean age of 47.5 years (range: 18-80 years; 95% confidence interval [CI]: 43.9-51.2 years). Topical steroids delivered by any method significantly improved TSS in CRSsNP patients (Δ0.4; 95% CI: 0.3-0.6; p < 0.0001). When stratified by allergy status, CRSsNP patients without allergy had significantly improved TSS when treated with EDS (Δ0.4; 95% CI: 0.1-0.7; p = 0.01), but not with topical spray (Δ0.04; 95% CI: -0.9 to 1.0; p = 0.94). Patients treated with EDS or sinonasal catheter responded significantly better compared to placebo (odds ratio [OR]: 3.4; 95% CI: 1.9-6.0; p < 0.0001; OR: 12.4; 95% CI: 1.8-83.8; p < 0.01), whereas patients treated with topical spray had no significant difference (OR: 1.8; 95% CI: 0.9-4.0; p = 0.12). CONCLUSIONS: Topical steroids are effective in treating CRSsNP, especially when delivered via EDS or sinonasal catheter. Future trials comparing steroid delivery mechanisms using validated outcome measures in CRSsNP populations are needed.

Medical Management of Headache and Facial Pain in CRS: A Systematic Review and Meta-Analysis.

OBJECTIVES: This study aims to characterize the effect of medical therapy on headache and facial pain/pressure among patients with chronic rhinosinusitis (CRS). DATA SOURCES: CINAHL, PubMed, and Scopus. METHODS: CINAHL, PubMed, and Scopus were searched from inception through April 10th, 2024, for English language articles reporting headache or facial pain/pressure outcomes in CRS patients. Inclusion was restricted to studies reporting results of the medical treatment of CRS in nonsurgical cohorts. Primary outcome measures included the sino-nasal outcome test (SNOT) and the visual analogue scale (VAS). Meta-analyses of continuous measures (mean), mean difference (Δ), and proportions (%) were conducted. RESULTS: The initial search yielded 2429 unique articles. After a full-text review of 272 articles, 17 studies reporting outcomes for 2269 patients were included in the meta-analysis. The mean patient age was 48.6 years (range 18.0-86.0; 95% CI: 46.5 to 50.6), among which 55.4% (95% CI: 51.5 to 59.4) were male and 82.9% (95% CI: 68.8 to 93.4) had nasal polyposis. SNOT facial pain/pressure scores improved by 1.1 points (95% CI: -1.7 to -0.5; relative reduction 40.4%) with non-biologic therapies and 1.0 point (95% CI: -1.4 to -0.6; relative reduction 54.6%) with biologic therapies. On an 11-point scale, VAS headaches scores improved by 1.8 units (95% CI: -3.3 to -0.3; 42.1% relative reduction) in CRSwNP patients and 1.0 unit (95% CI: -1.7 to -0.3; 54.0% relative reduction) in CRSsNP patients. CONCLUSIONS: Our findings suggest medical therapy significantly reduces facial pain and pressure in the CRS population. Laryngoscope, 2024.

Surgical management of headache and facial pain/pressure in chronic rhinosinusitis: A systematic review and meta-analysis.

BACKGROUND: Headache and facial pain are common symptoms of chronic rhinosinusitis (CRS). However, given the numerous etiologies that can cause these symptoms, the impact of sinus surgery is not well characterized. METHODS: A systematic review was performed by searching the literature from inception through June 6, 2023. English-language articles reporting outcomes for facial pain/pressure or headache following endoscopic sinus surgery were selected for inclusion. Meta-analyses were performed using random and fixed effect models on continuous measures (mean), mean difference (Δ), and proportions (%). RESULTS: A total of 26 articles reporting on 2839 patients were selected for inclusion. The mean patient age was 44.0 ± 3.9 (range 16.0-84.0), with an average symptom duration of 5.3 ± 2.8 years. Among these patients, 56.5% (95% confidence interval [CI]: 52.3-60.6) were male and 77.0% (95% CI: 56.6-92.3) had nasal polyposis (NP). Patients with and without NP reported substantial reductions in both 22-item sino-nasal outcome test facial pain/pressure (with NP: -1.4 [95% CI: -1.6 to -1.2; relative reduction 59.1%]; without NP: -1.5 [95% CI: -1.9 to -1.1; relative reduction 60.9%]) and visual analogue scale (VAS) headache (with NP: -2.5 [95% CI: -2.8 to -2.1; relative reduction 67.2%]; without NP: -2.8 [95% CI: -4.7 to -1.0; relative reduction 42.7%]). Symptom reductions were greater in the without NP versus with NP group; VAS facial pain/pressure: Δ0.4 (95% CI: 0.2-0.6; p = 0.0006) and VAS headache: Δ0.4 (95% CI: 0.1-0.7; p = 0.02). CONCLUSIONS: Our findings suggest that CRS patients, regardless of polyp status, benefit from significant reductions in facial pain/pressure and headache following surgical therapy.

Comparison of trigeminal lateralization with differing stimulants.

Trigeminal-specific stimulants have been shown to activate different receptors preferentially and this likely accounts for variation in sensory perception. It is unclear whether trigeminal sensitivity is similar across different transient receptor potential (TRP) receptors or if dysfunction of different receptors results in differing patient symptoms. Therefore, a prospective cohort study was conducted, consisting of trigeminal lateralization testing with three different stimulants (eucalyptol, isothiocyanate, acetic acid), olfaction testing with Sniffin' Sticks, and measurement of various patient-reported outcome measures (PROMs). A total of 50 participants were enrolled across the olfactory spectrum. Mean TDI score was 27.1 ± 8.3 (range 7.0-39.5) with 38% normosmic and 62% dysosmic. Mean trigeminal lateralization scores out of 20 in the overall cohort were 16.18 (2.78) for eucalyptol, 14.94 (3.49) for mustard oil, and 15.28 (3.68) for vinegar. Eucalyptol showed a significant correlation with threshold scores of Sniffin' Sticks. A significant correlation was found between acetic acid and various PROMs. None of the lateralization scores of the trigeminal stimulants correlated to each other significantly and there was no correlation to age. The lack of correlation suggests that the measured sensitivity of one type of TRP receptor may not translate to similar sensitivity of the other receptors. Additional investigations with TRPV1 and TRPA1 agonists are needed to corroborate our findings.

Prognosis of Bilateral Sudden Sensorineural Hearing Loss: A Systematic Review and Meta-Analysis.

OBJECTIVES: To comprehensively examine the characteristics and prognosis of bilateral sudden sensorineural hearing loss (BSSHL) and its subtypes compared to unilateral sudden sensorineural hearing loss (USSHL). DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: Databases were searched from inception to December 5, 2023, for studies reporting patient characteristics and audiometric outcomes for BSSHL and its simultaneous (Si-BSSHL) and sequential (Se-BSSHL) subtypes. Meta-analysis of continuous measures, proportions (%), mean differences (Δ), and odds ratio (OR) were performed. RESULTS: Eleven studies were included, consisting of 368 patients with BSSHL and 2,705 patients with USSHL. The pooled prevalence among all SSHL cases was 88.1% (95% CI: 81.2%-93.6%) for USSHL and 11.9% (95% CI: 6.4% to 18.8%) for BSSHL. PTA improvement following treatment with steroids was significantly worse in patients with BSSHL (Δ15.3 dB; 95% CI: 14.6 to 15.9; p < 0.0001) compared to patients with USSHL. There was no significant difference in post-treatment PTA improvement between the BSSHL subtypes. Patients with Si-BSSHL were significantly less likely to have an idiopathic etiology (OR: 0.4; 95% CI: 0.2 to 0.8; p = 0.01) and significantly more likely to have an autoimmune disease etiology (OR: 27.4; 95% CI: 2.2 to 336.1; p = 0.01), comorbid cardiovascular disease (OR: 2.3; 95% CI: 1.1 to 5.1; p = 0.03), and comorbid hypertension (OR: 2.5; 95% CI: 1.6 to 3.8; p < 0.0001) compared to patients with USSHL. CONCLUSIONS: BSSHL is a considerably rarer form of SSHL with worse prognosis compared to USSHL. BSSHL, and Si-BSSHL in particular, has significantly greater associations with systemic pathologies compared to USSHL. Laryngoscope, 134:3883-3891, 2024.

Sexual history of patients with human papillomavirus positive and negative oropharyngeal cancer: A systematic review and meta-analysis.

BACKGROUND: Increased sexual activity is associated with higher human papillomavirus (HPV) rates; however, there is a lack of analysis comparing the sexual history of patients with HPV positive and HPV negative oropharyngeal cancer (OPC). METHODS: In this meta-analysis, PubMed, Scopus, and CINAHL were searched for articles that included patients with OPC and reported information regarding HPV status and either history of oral sex, number of sexual partners, or sexually transmitted infections (STI). RESULTS: A total of 11 studies were included with 3296 patients with OPC. Patients with HPV positive OPC were more likely than patients with HPV negative OPC to report a history of oral sex (92%, 95% CI: 87.0-97.0 vs. 74.5%, 95% CI: 50.6-98.4, p < 0.0001), higher mean number of sexual partners (18.4 partners, 95% CI: 1.5-35.4 vs. 7.2 partners, 95% CI: 1.0-13.4, p < 0.0001), and more frequent history of STI (23.7%, 95% CI: 18.4-29.0 vs. 8.8%, 95% CI: 4.7-12.8, p = 0.0001). CONCLUSIONS: Compared to patients with HPV negative OPC, our analysis shows a larger proportion of patients with HPV positive OPC had participated in oral sex, had a higher number of sexual partners, and had a higher proportion of STI history.

Vascular events in patients with head and neck cancer: A systematic review and meta-analysis.

OBJECTIVE: To assess the incidence of vascular events in patients with head and neck cancer. REVIEW METHODS: Primary studies identified through April 2023. Meta-analysis was performed. RESULTS: There were 146 studies included in the systematic review. Rates of events were collected in the overall group, those with chemoprophylaxis, and those that underwent surgery, radiation, or chemotherapy. Of 1 184 160 patients, 4.3% had a vascular event. Radiation therapy had highest risk of overall events and stroke when compared to surgery and chemotherapy. Chemotherapy had a higher risk of stroke and overall events when compared to surgery. CONCLUSIONS: Vascular events occur in 4%-5% of patients with head and neck cancer. Our data does not support the use of routine anticoagulation. Patients undergoing radiation therapy had the highest frequency of events.

Characteristics and outcomes of interventions for pediatric laryngomalacia: A systematic review with meta-analysis.

OBJECTIVES: To analyze characteristics of children treated for laryngomalacia to determine predictive factors and provide an updated meta-analysis on outcomes. METHODS: A systematic review was conducted according to PRISMA guidelines from inception to May 2, 2023, using CINAHL, PubMed, and Scopus databases. Study screening, data extraction, quality rating, and risk of bias assessment were performed by 2 independent reviewers. Data were meta-analyzed using fixed-/random-effects model to derive continuous measures (mean), proportions (%), and mean difference (Δ) with 95% confidence interval (CI). RESULTS: 100 articles were identified with information on outcomes of pediatric patients with laryngomalacia (N = 18,317). The mean age was 10.6 months (range: 0 to 252, 95%CI: 9.6 to 11.6, p = 0.00) with a 1.4:1 male to female ratio. Many patients presented with stridor (87.9%, 95% CI: 69.8 to 98.4), and the most common comorbidity at time of diagnosis was gastroesophageal reflux disease (48.8%, 95%CI: 40.9 to 56.8). Based on the patient population included in our analysis, 86.1% received supraglottoplasty (95% CI: 78.7 to 92.1). A total of 73.6% (95% CI: 65.5 to 81.0) had reported complete resolution of symptoms. For patients with a concurrent diagnosis of sleep disordered breathing receiving supraglottoplasty, the apnea-hypopnea index improved with a mean difference of -10.0 (95%CI: 15.6 to -4.5) events per hour post-treatment. CONCLUSIONS: Laryngomalacia continues to be a common problem in the pediatric population. Supraglottoplasty remains an effective treatment option leading to symptomatic improvement in many cases.

The Placebo Effect on Tinnitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: To quantify the placebo effect in randomized clinical trials treating tinnitus with oral or intratympanic placebo treatment. DATA SOURCES: CINAHL, PubMed, and Scopus were searched for articles from conception to October 2022. MESH and key terms such as "tinnitus," "placebo," and "medication" were used to find randomized, placebo-controlled trials. The search was limited to articles in English. METHODS: Randomized controlled trials with adult subjects evaluating tinnitus pretreatment and posttreatment with an oral or intratympanic medication versus a placebo arm were included. Crossover studies, studies involving middle/inner ear operations or devices, and studies that exclusively included nonidiopathic etiologies of tinnitus were excluded. Mean tinnitus symptom survey scores for the Tinnitus Handicap Inventory (THI), Tinnitus Severity Index, Tinnitus Functional Index, Tinnitus Handicap Questionnaire, and Visual Analog Scales for tinnitus Intensity/Loudness (VAS-L), Annoyance (VAS-An), and Awareness (VAS-Aw) were extracted for both placebo and experimental groups. RESULTS: 953 studies were screened with 23 studies being included in the final analysis. Meta-analysis of mean difference (MD) was calculated using RevMan 5.4. MD between pretreatment and posttreatment THI scores of the placebo arms was 5.6 (95% confidence interval, 3.3-8.0; p < 0.001). MD between pretreatment and posttreatment VAS scores of the placebo groups for Loudness, Annoyance, and Awareness were 0.8 (0.0 to 1.6, p = 0.05), 0.2 (-0.2 to 0.5, p = 0.34), and 0.3 (-0.0 to 0.7, p = 0.08), respectively. CONCLUSIONS: Placebo treatment has shown effectiveness in improving patient-reported evaluations of tinnitus when using some standardized metrics such as THI and VAS-L; however, the improvement is not as substantial as nonplacebo treatment.
