Objective: To determine if librarian collaboration was associated with improved database search quality, search reproducibility, and systematic review reporting in otolaryngology systematic reviews and meta-analyses.

Methods: In this retrospective cross-sectional study, PubMed was queried for systematic reviews and meta-analyses published in otolaryngology journals in 2010, 2015, and 2021. Two researchers independently extracted data.

Article Synopsis
  • Trigeminal-specific stimulants activate different receptors, leading to variations in how sensory perception is experienced, but it's unclear if this sensitivity is uniform across various TRP receptors.
  • A study was conducted with 50 participants to test trigeminal sensitivity using three stimulants (eucalyptol, isothiocyanate, acetic acid) and olfaction assessments, revealing mixed results in sensitivity and correlations.
  • The findings indicate that there is no significant correlation between the sensitivity of different TRP receptors or with age, suggesting that dysfunction in these receptors may cause different symptoms, warranting further research on TRPV1 and TRPA1 receptor interactions.

Background: The current standard of drawing two vs three blood culture sets lacks adequate guidance. Because people who inject drugs are at higher risk for bacteraemia and life-threatening infection, consideration of a third blood culture becomes more important.

Aim: To investigate the risks and benefits of obtaining two versus three blood culture sets.

Background: Current methods of quantifying inflammation in chronic rhinosinusitis (CRS) on computed tomography (CT) imaging focus on opacification of the paranasal sinuses and show limited correlation with patient-reported outcome measures.

Objective: This study aimed to determine if quantifying CT opacification of the nasal cavity correlated with Sino-Nasal Outcomes Test scores (SNOT-22).

Methods: Thirty patients with CRS were enrolled.

Objectives: To determine the effect of developmental delay (DD) and autism spectrum disorder (ASD) on pediatric external auditory canal foreign body (EAC FB) retrieval outcomes.

Methods: A retrospective chart review of children presenting with EAC FB at a tertiary children's hospital was performed between January 2018 and December 2019. Charts were reviewed for demographics, presence of otalgia, complications, number of EAC FB episodes, indications for operating room removal, DD, and ASD status.

Objectives: To examine the volume, topics, and reporting trends in the published literature of randomized clinical trials for pharmacologic pain management of pediatric tonsillectomy and adenotonsillectomy and to identify areas requiring further research.

Data Sources: PubMed (National Library of Medicine and National Institutes of Health), Scopus (Elsevier), CINAHL (EBSCO), and Cochrane Library (Wiley).

Methods: A systematic search of four databases was conducted.

Objective: To provide an updated comparison of apnea-hypopnea index (AHI), oxygen desaturation index (ODI), respiratory disturbance index (RDI), oxygen saturation (O sat), and lowest oxyhemoglobin saturation (LSAT) measured by portable sleep study devices (PSSDs) compared to polysomnography (PSG).

Data Sources: Primary studies were identified through PubMed, Scopus, CINAHL, and Cochrane.

Review Methods: A systematic review was performed by searching databases from inception through August 2021.

Background: Trismus is a common symptom for patients with head and neck cancer. This study aimed to evaluate outcomes using the novel Trismus Intra-operative Release and Expansion (TIRE).

Methods: All patients from 2012 to 2022 with histories of head and neck cancers and trismus treated with TIRE were included.

Introduction: Patients often describe the olfactory loss as either the inability to detect unpleasant odors (eg, smoke or spoiled food) or noticeable impairment in enjoying pleasant odors (eg, food and fragrances). This complex relationship between the hedonics of various odors, their perceived magnitude in odor strength, and the impact on patient quality of life is not well understood.

Methods: Sixty-five subjects underwent testing with the Henkin olfaction test which assesses hedonics and magnitude for odors traditionally deemed unpleasant (pyridine/dead fish and thiophene/gasoline) and pleasant (amyl acetate/banana and nitrobenzene/almond).

Objective: To determine if exfoliation syndrome (XFS) is associated with hearing loss (HL) or vestibular dysfunction.

Data Sources: PubMed, Scopus, CINAHL, and Cochrane Library through April 1, 2022.

Review Methods: Two reviewers independently screened abstracts, selected articles for inclusion, and extracted data.

Purpose: Perioperative anxiety can significantly alter outcomes for pediatric patients. Parental presence at induction of anesthesia (PPIA) is one method of anxiety reduction, but the efficacy remains unclear. This systematic review and meta-analysis aimed to determine if PPIA affects child and caretaker perioperative anxiety levels.

Introduction: Psoriatic skin lesions are often seen in the auricle and external auditory canal, but middle ear and inner ear manifestations are not easily identified. Several studies have indicated hearing loss and vestibular dysfunction with psoriasis, but the extent of association has not been well defined.

Methods: A systematic search of PubMed, CINAHL, Scopus, and Cochrane Library was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Introduction: During the SARS-CoV-2 pandemic, the incidence of pediatric button battery (BB) ingestions has risen. Children have spent more time at home from school, while many parents try to balance working from home and childcare. Additionally, the amount of electronics powered by BB has increased.

Article Synopsis
  • * After analyzing 13 studies with nearly 4,000 patients, results showed that Otolaryngologists had the highest success rate at 92.9% when no prior attempts at removal were made, while Emergency Departments had the lowest at 64.0%.
  • * The findings suggest that prior attempts at removal by other healthcare providers may decrease success rates for Otolaryngologists due to complications like decreased patient cooperativeness and ear canal injuries, highlighting the need for improved collaboration among healthcare settings for better patient outcomes.

Objective: To examine the effectiveness of Eustachian tube procedures for the treatment of baro-challenge Eustachian tube dysfunction.

Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, databases, including PubMed (National Library of Medicine, National Institutes of Health), Scopus (Elsevier), and CINAHL (EBSCO), were searched for articles examining the effectiveness of Eustachian tube procedures for baro-challenge Eustachian tube dysfunction. Outcome measures included symptom resolution, ability to return to work, equalization problems (EP) scores, Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores, and pressure chamber testing parameters.

Background: Otologic symptoms consistent with Eustachian tube dysfunction (ETD) are common in patients with chronic rhinosinusitis (CRS), but can also occur independently of CRS as primary ETD. It is unclear if CRS+ETD is similar to primary ETD or how treatment outcomes compare.

Methods: A systematic search of PubMed, CINAHL, Scopus, and Cochrane Library was conducted following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA).
