Lower Cranial Nerves in the Neck: An Anatomical Study.

Objectives The aim of this anatomical study was to analyze distances and anatomical relations between the lower cranial nerves and important neck landmarks. Methods Anatomical study based on neck dissection in Thiel-embalmed cadavers. Anatomical relations and distances between the vagus (X), accessory (XI), and hypoglossal (XII) nerves and important neck landmarks were registered and compared.

Laryngeal dystonia and vocal tremor response to botulinum toxin injection.

Purpose: The main objective of this study was to compare laryngeal dystonia (LD) and vocal tremor's (VT) response to botulinum toxin injection.

Methods: Retrospective study including every patient with LD or VT injected with botulinum toxin guided by electromyography, from January 1, 2010, to September 30, 2022, at a tertiary hospital centre. Improvement was assessed with the VHI-10, grade of dysphonia in a visual analogue scale (VAS; 0-10), GRBAS(I) scale (0-3) and maximum phonation time (MPT).

Nodal Yield in Level II-IV Neck Dissections in Head and Neck Squamous Cell Carcinoma.

Objectives: The main objective of this study is to analyze factors associated with nodal yield in level II-IV selective neck dissections (NDs) and the secondary objective is to assess its impact on overall and disease-free survival.

Methods: Observational retrospective study including adult patients submitted to level II-IV ND from January 2015 to December 2021 in the otorhinolaryngology department of a tertiary hospital center.

Results: A total of 44 patients and 78 level II-IV NDs (34 bilateral and 10 unilateral) were included.

Rigid Esophagoscopy for Foreign Body Extraction: Results and Complications in the Endoscopic Era.

Introduction Rigid esophagoscopy (RE) has long been a part of otolaryngology practice. In the past decades, the procedure was less commonly performed due to the advances and availability of flexible endoscopic techniques. This study aims to describe the outcomes of RE performed to treat foreign body ingestion and to evaluate risk factors associated with postoperative complications.

Laryngeal Dystonia, Dystonic Tremor and Vocal Tremor: Three Different Entities.

Objective: The main objective of this study was to compare the demographic and clinical characteristics of patients with laryngeal dystonia (LD), dystonic tremor (DT), and vocal tremor (VT).

Study Design: This was a retrospective longitudinal study.

Methods: Data analysis from every patient diagnosed with LD, DT, or VT from January 1, 2010, to September 30, 2022, at a tertiary hospital center.

Comparison of Clinical and Pathological Staging in Patients with Head and Neck Cancer After Neck Dissection.

 Clinical and pathological staging plays an important role on the prognosis of head and neck cancer (HNC) patients.  The present study aims to compare clinical and pathological T, N and overall staging in patients with HNC, to identify factors associated with these discrepancies, and to analyze and compare survival or disease-free survival in staging disagreements.  Retrospective cohort including every patient submitted to neck dissection from January 2010 to December 2020 in the department of Otorhinolaryngology of a tertiary hospital center.

Allergic Rhinitis Seasonality, Severity, and Disease Control Influence Anxiety and Depression.

Objectives: Allergic rhinitis (AR) has been associated with anxiety and depression. A possible influence of frequency and intensity of the AR symptoms has remained unclear. Therefore, we evaluated the association between AR, as well as its control, seasonality and severity, and the presence of anxiety and depression.

Increased choroidal thickness is not a disease progression marker in keratoconus.

The recent findings of increased Choroidal Thickness (CT) in Keratoconus (KC) patients raised the question of whether CT could be an indicator of progressive KC. To test this hypothesis, we evaluated and compared the choroidal profile in progressive and non-progressive KC. We ran a cross-sectional observational study in 76 patients diagnosed with KC, age 14-30, to assess KC progression.

Development of two artificial neural network models to support the diagnosis of pulmonary tuberculosis in hospitalized patients in Rio de Janeiro, Brazil.

Pulmonary tuberculosis (PTB) remains a worldwide public health problem. Diagnostic algorithms to identify the best combination of diagnostic tests for PTB in each setting are needed for resource optimization. We developed one artificial neural network model for classification (multilayer perceptron-MLP) and another risk group assignment (self-organizing map-SOM) for PTB in hospitalized patients in a high complexity hospital in Rio de Janeiro City, using clinical and radiologic data collected from 315 presumed PTB cases admitted to isolation rooms from March 2003 to December 2004 (TB prevalence = 21.
