Two Teflon granulomas of the nasopharynx and paravertebral space mimicking a neoplasm.

Teflon has been proved to be able to extravasate and infiltrate into soft tissue to form an inflammatory giant-cell foreign-body reaction, a so-called Teflon granuloma. We present a rare case report of a patient with two Teflon granulomas of the head and neck, who were first interpreted as a neoplasm.

Brazilian Consumers' Perception towards Food Labeling Models Accompanying Self-Service Foods.

The study aimed to evaluate consumers' perception of self-service foods' nutrition labels. This qualitative and quantitative assessment was performed with potential consumers at food services. Four food labeling formats, traditional, simplified, traffic-light, and warning, were proposed to evaluate three types of sandwiches: simple, chicken, and hamburger.

Endoscopic and Computed Tomography Evaluation of Posterior Glottic Closure During Phonation.

Objectives/hypothesis: The anatomy of the posterior glottis, specifically the states of the posterior glottis during phonation, has not been thoroughly explored in laryngology. Conventional wisdom about the posterior glottis indicates that it tends to be completely closed in men but may be open in women. Furthermore, professional singers are expected to have a completely closed posterior glottis.

An Old Myth: Prediction of the Correct Singing Voice Classification. True or not?

Objective: Predicting the correct singing voice classification based on laryngoscopy is an old myth. The aim of this study was to evaluate if a professional phoniatrician/laryngologist can predict the correct singing voice classification only from laryngoscopy and to analyze different anatomical parameters between professional sopranos and altos to determine whether a multivariate analysis of anatomical parameters can predict the singing register.

Study Design: Prospective study METHODS: We included 49 professional female singers (25 sopranos, 24 altos).

[ReSi: Evaluation of a Program for Competency Training and Prevention of Sexual Abuse in Kindergarten].

This paper describes the "ReSi-Kompetenzförderprogramm" and its evaluation. Based on the resilience approach, this programme aims to foster the social-emotional, body-related and linguistic competencies of kindergarteners and teach them age-appropriate preventive knowledge concerning sexual abuse. A randomized-controlled trial was conducted (n = 412).

Absence of the neutrophil serine protease cathepsin G decreases neutrophil granulocyte infiltration but does not change the severity of acute pancreatitis.

Acute pancreatitis is characterized by an early intracellular protease activation and invasion of leukocytes into the pancreas. Cathepsins constitute a large group of lysosomal enzymes, that have been shown to modulate trypsinogen activation and neutrophil infiltration. Cathepsin G (CTSG) is a neutrophil serine protease of the chymotrypsin C family known to degrade extracellular matrix components and to have regulatory functions in inflammatory disorders.

Effect of Vocal Fold Implant Placement on Depth of Vibration and Vocal Output.

Objective: Most type 1 thyroplasty implants and some common injectable materials are mechanically stiff. Placing them close to the supple vocal fold mucosa can potentially dampen vibration and adversely impact phonation, yet this effect has not been systematically investigated. This study aims to examine the effect of implant depth on vocal fold vibration and vocal output.

A 5G V2X Ecosystem Providing Internet of Vehicles.

The Fifth Generation (5G) cellular network can be considered the way to the ubiquitous Internet and pervasive paradigm.The Internet of Vehicles (IoV) uses the network infrastructure to allow cars to be connected to new radio technologies, and can be supported by 5G networks. In this way, the Vehicle-to-Everything (V2X) integration needs 5G connections unavoidably.

Changes in Vocal Fold Morphology During Singing Over Two Octaves.

Objective: Vocal folds are widely assumed to only elongate to raise vocal pitch. However, the mechanisms seem to be more complex and involve both elongation and tensioning of the vocal folds in series. The aim of the present study was to show that changes in vocal fold morphology depend on vocal fold elongation and tensioning during singing.

How Age and Frequency Impact the Thyroid Cartilages of Professional Singers.

Objectives/hypothesis: Young professional singers can easily reach very high pitches. In contrast, older singers often complain that they have to exert substantially more laryngopharyngeal force to reach the same high pitch compared with their earlier years. Various factors such as the property changes of the mucosa and ossification that impact the singing apparatus were suggested as explanations in the literature.

Cricothyroid joint type as predictor for vocal fold elongation in professional singers.

Objective: Vocal fold (VF) elongation vocal folds depends on two factors: the activity of the laryngeal muscles and the cricothyroid joint (CTJ). The aim of the study was to show the influence of the CTJ on VF elongation while singing a sustained vowel at different pitches.

Study Design: Prospective study.
