Are hearing protection devices used in the workplace really efficient? A systematic review.

Background: The most common current hearing protection devices (HPDs) on the market include earplugs and earmuffs. A variety of materials can be used to manufacture these devices, and each offers a level of noise attenuation that is informed by the manufacturer although it does not always correspond to the attenuation observed in real-world use.

Objective: To evaluate the noise attenuation of HPDs available to workers exposed to noise.

Purpose: Translate into Brazilian Portuguese and culturally adapt the component scores definition from the Modified Barium Swallow Impairment Profile - MBSImP videofluoroscopy protocol.

Methods: This study was conducted based on international guidelines for creation, translation and transcultural adaptation according to domestic publications for the validation of international speech-language pathology tests. A specialist committee was convened with two otorhinolaryngologists and three speech-language pathologists familiar with videofluoroscopy examinations.

Five-Year Longitudinal Cohort Study Determines the Critical Intervals for Periodic Audiometric Testing Based on 5070 Tests of Metallurgical Workers Exposed and Nonexposed to Noise.

Objectives: To compare the progression of 3-, 4-, and 6-kHz thresholds (pure-tone average) over 5 years and determine the most critical period for occupational risk among workers exposed and nonexposed to noise.

Design: Metallurgical workers were divided into 2 groups: noise-exposed and non-noise-exposed groups. The 6 initial audiometric tests of each worker were analyzed as baseline test and annual tests 1 to 5.

Home sleep apnea testing: an accuracy study.

Aim: There are no studies comparing tests performed at home with those carried out in the laboratory, using the same device. The only studies that have been performed have compared the device used at home with the standard polygraph used in the laboratory. The purpose of this study was therefore to verify the accuracy of the home diagnosis of obstructive sleep apnea syndrome (OSAS) via unassisted type 2 portable polysomnography, compared with polysomnography using the same equipment in a sleep laboratory.

Is it necessary to perform occupational audiometric testing at 6-months of employment?

Introduction: Current Brazilian legislation requires that all workers exposed to noise are to be given an audiogram upon hiring, after 6 months of employment (first periodic test), and annually after the first periodic test. In other countries, the regulations of hearing conservation programs do not include the requirement for audiometric testing at 6 months of employment, but only annually. There is no evidence that the periodicity adopted by Brazilian legislation is the most appropriate.

Thorax necrotizing fasciitis following Bezold's abscess.

Bezold's abscess is a rare complication of acute otitis media, but it should be recognized and aggressively treated. Otolaryngologists must be aware of this diagnosis, and multidisciplinary care should be provided as soon as possible.

Laryngeal electromyography in amyotrophic lateral sclerosis.

Background: Bulbar involvement is a hallmark of amyotrophic lateral sclerosis (ALS), but surprisingly very few studies have addressed the frequency, pattern and clinical relevance of laryngeal involvement in the disease.

Methods: Twenty-six patients with spinal-onset ALS underwent nasofibroscopy (NF), followed by laryngeal electromyography (LEMG). We also studied resting activity and motor unit potentials of the genioglossus and masseter muscles.

Effect of Noise Exposure on 1,382 Metallurgical Workers in Periodic Audiometric Evaluation: A Cohort Study.

Introduction: Noise-induced hearing loss is the most preventable cause of auditory impairment. Periodic audiometric evaluations are essential to monitor the hearing health of noise-exposed workers.

Objective: To compare the evolution of audiometric thresholds in the initial three evaluations at frequencies of 3, 4, and 6 kHz in groups of workers exposed or not to noise.

Asystole during Suspension Laryngoscopy: Case Report, Literature Review, and Prophylactic Strategies.

Transoral laryngeal procedures are considered minimally invasive but may trigger important complications such as severe bradycardia and even asystole mediated by vagal reflex. The literature on this subject is rare. This article aims to review the literature, explain associated mechanisms, establish prophylactic strategies, and highlight the importance of intraoperative safety protocols.

Clinicopathologic Diagnostic and Prognostic Factors of Spindle Cell Carcinoma of Upper Airway.

Spindle cell carcinoma (SpCC) is a rare tumor, which occurs in upper respiratory tract, mainly in larynx. This study aimed to review the clinical and pathological characteristics for diagnosis and prognosis. Retrospective cohort study.

Tonsillar Lymphoma in Children According to Age Group: A Systematic Review.

Introduction: Lymphoma is a common malignant tumor of the head and neck occurring during childhood. Early diagnosis is very important in terms of prognosis in patients with tonsillar lymphoma.Our objective was to evaluate the clinical manifestations of pediatric tonsillar lymphoma according to different age groups.

Histologic correlation of VEGF and COX-2 expression with tumor size in squamous cell carcinoma of the larynx and hypopharynx.

The prognosis and survival of patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC) are related to the clinical staging. Tumor growth and metastasis are closely related to angiogenesis. Vascular endothelial growth factor (VEGF) and cyclooxygenase 2 (COX-2) are intimately related to the angiogenic process in which the blood supply required for neoplastic evolution is ensured.

Assessment of Grade of Dysphonia and Correlation With Quality of Life Protocol.

Objective: The main objective of this study is to check the correlation between vocal self-assessment and results of the Voice-Related Quality of Life (V-RQOL) protocol, and whether there is a correlation between perceptual vocal assessment made by voice therapists and the results from the V-RQOL protocol.

Study Design: The study included 245 subjects with vocal complaints. This was a prospective analytical clinical study.

Deep neck abscesses: study of 101 cases.

Introduction: Although the incidence of Deep Cervical Abscess (DCA) has decreased mainly for the availability of antibiotics, this infection still occurs with considerable frequency and can be associated with high morbidity and mortality.

Objective: This study aimed to present our clinical-surgical experience with deep neck abscesses.

Methods: A retrospective study analyzed 101 patients diagnosed with deep neck abscesses caused by multiple etiologies, assisted at a medical school hospital during 6 years.

Laryngeal Electromyography Techniques and Clinical Use.

Laryngeal electromyography is considered a valuable diagnostic tool for voice disorders. The technique, described almost 70 years ago, evolved 3 decades later, mainly because of the growing interest of laryngologists and speech pathologists. In the authors' opinion, the reduced number of neurophysiologists involved in laryngeal electromyography groups is, at some instance, related to the difficulty to start the learning process and the multidisciplinary approach the field requires.

Correlation between vascular endothelial growth factor expression and presence of lymph node metastasis in advanced squamous cell carcinoma of the larynx.

Introduction: Squamous cell carcinoma is the most common neoplasm of the larynx, and its evolution depends on tumor staging. Vascular endothelial growth factor is a marker of angiogenesis, and its expression may be related to increased tumor aggressiveness, as evidenced by the presence of cervical lymphatic metastases.

Objectives: To evaluate the expression of the vascular endothelial growth factor marker in non-glottic advanced squamous cell carcinoma of the larynx (T3/T4) and correlate it with the presence of cervical lymph node metastases.
