The role of phagocytes of children with cystic fibrosis (CF) associated with different phenotypes of chronic rhinosinusitis (CRS) is unclear. The aim of this study was to evaluate the phagocytic capacity of blood neutrophils and monocytes and production of superoxide anion by phagocytes in patients with CF with or without chronic rhinosinusitis and with or without nasal polyps (NP). This cross-sectional study was established in 2015-2017 in a tertiary reference center to the CF treatment, Brasilia, Brazil.

There is a consensus that arterial hypertension (AH) is associated with stroke. Therefore, this study aimed to evaluate the histology of the microvasculature associated with the mucosa of the posterior nasal cavity to identify possible factors related to vascular weakening and rupture. Histological sections were obtained from hypertensive and normotensive individuals, regardless of epistaxis.

Unlabelled: "Among the most common occupations, schooteachers are the ones who experience the most changes throughout their career. Considering this, the present study aims to verify whether dysphonia in three different degrees may compromise the speech intelligibility of schoolteachers in the classroom.

Method: Overall, 39 students, average age 10 years, randomly selected from a public school in the Federal District, Brazil (Distrito Federal, Brasil) performed a transcription task of 20 sentences spoken by four distinct female voices in a classroom, one with a control voice (normal), another with mild dysphonia, 1 with moderate dysphonia and another with severe dysphonia.

Statement Of Problem: What are the normative data available on the perceptual and acoustic characteristics of the voice of adults of both sexes who have hearing-impairment and who use cochlear implants?

Purpose: To identify in the literature, normative data about the perceptual auditory and acoustic characteristics of the voice of hearing-impaired cochlear implant adult users.

Search Strategy: A systematic search was carried out in the Virtual Health Library, Web of Science, Science Direct, SciELO, and SCOPUS databases with no temporal restriction.

Selection Criteria: The articles were selected if they led with citation to normative data of the acoustic analysis of the voice of deaf cochlear implant users.

Introduction: Age-related hearing loss (ARHL) is a consequence of aging of the auditory system. The best known mechanism of cell death in ARHL is apoptosis due to increased production of reactive oxygen species. In this context, it is hypothesized that melatonin, owing to its high antioxidant potential and its action in the mitochondria, helps prevent or delay outer hair cell dysfunction (HCD).

Background/aim: Cisplatin is a highly effective chemotherapeutic agent that is used to treat solid tumors; however, its severe side effects remain a limitation. In particular, the high incidence of cisplatin-induced ototoxicity has attracted interest. Melatonin has been shown to decrease the toxic effects of cisplatin due to its antioxidant activity, and could increase the efficacy of cancer chemotherapy.

Purpose: To assess whether significant changes in smell perception occur after septorhinoplasty, and evaluate whether septum deviation, allergic rhinitis, and surgical technique affect postoperative smell perception.

Methods: Thirty-four patients (> 18 years old) awaiting septorhinoplasty were included, while those with previous severe hyposmia or anosmia were excluded. The participants self-assessed their smell perception using a 100-mm visual analogue scale (VAS), where 0 mm indicated the inability to smell and 100 mm indicated normal smell perception.

 Acromegaly is a chronic disease caused by growth hormone (GH) excess due to a GH-secreting pituitary adenoma in most cases. There is reasonable data to presume the possible influence of chronic GH and insulin-like growth factor I (IGF-I) hyperproduction on the anatomical structures involved in normal sound perception, and on its conductive and/or sensorineural part.  To review the literature about acromegaly and hearing loss.

Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD), partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL) has been considered a hallmark of incomplete ossicular discontinuity.
