Cultural Adaptation Quality of Family Life Scale for the Brazilian Portuguese.

Purpose: To culturally adapt the Family Quality of Life Scale to the Brazilian Portuguese version and evaluate the instrument reliability and family quality of life of those who have children with hearing loss.

Methods: The process of cultural adaptation of the scale followed the steps of the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measure. It was conducted in three stages: translation, back translation, and application in a pilot sample, as a way to check the comprehension difficulties of the items.

Distortion-product otoacoustic emission growth curves in neonates.

Background: The recording of otoacoustic emissions (OAE) enabled us to prove that the cochlea is able not only to receive sounds but also to produce acoustic energy. Through the use of distortion-product otoacoustic emission measurements, the growth of the response was seen according to the intensity of the sound stimulus presented (growth curve).

Objective: to determine the thresholds for the emergence of distortion-product otoacoustic emissions (DPOAE) on frequencies of 2000 and 4000 Hz with a stimulus varying from 20 to 65 dB SPL, and to establish the slope values obtained in the growth curves.

Clinical and otorhinolaryngological aspects of extranodal NK/T cell lymphoma, nasal type.

Introduction: Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis.

Extramedullary nasal plasmacytoma: Literature review and a rare case report.

Introduction:  Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare.

Aim:  This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic.

Nasal paraganglioma: A case report and literature review.

Introduction:  Paragangliomas are neuroendocrine tumors that most commonly originate in the adrenal gland, a type that is called pheochromocytoma; however, 5-10% of paragangliomas are extra-adrenal and may arise in any area between the neck and pelvic region along the sympathetic nervous system. Those located in the head and neck comprise 3% of extra-adrenal tumors, with the majority originating in the tympanic-jugular region and carotid body.

Objective:  To present a rare case of nasal paraganglioma and review the literature.

Air caloric test in canal wall down mastoidectomy.

Unlabelled: Since the 1970s, few studies have been conducted to elucidate the use of caloric tests on middle ear disorders, despite the many controversies that this test may produce in anatomical structures that are so distinct. In cases of mastoidectomy, such studies are even rarer.

Objective: This study aims to analyze the findings from air caloric stimulation done in individuals submitted to unilateral radical mastoidectomy without complaints of dizziness.

Air stimulation in tympanic perforation: inverted nystagmus study.

Unlabelled: Response inversion during warm air stimulation is the most controversial finding seen in caloric tests of individuals with tympanic membrane perforation. In such cases, very few studies explore the possible interferences found in the caloric test, bringing about controversies in the interpretation of test results.

Aim: This paper aimed at analyzing warm air stimulation effects in individuals with tympanic membrane perforation in comparison with normal healthy controls.

Ricinus communis biocompatibility histological study in the nose of Cebus apella monkeys.

Unlabelled: Bone tissue lesions can be caused by congenital and acquired factors, and result in nasal deformities with cosmetic and functional repercussion. Surgical treatment in these cases frequently requires complex reconstructions and the use of biomaterials. The polyurethane derived from castor beans (Ricinus communis) has a favorable formulation in terms of ease of processing, flexibility, no emission of toxic vapors and low cost.

The characterization of the vibrato in lyric and sertanejo singing styles: acoustic and perceptual auditory aspects.

The vibrato is one of the embellishments most frequently used in the singing voice and it can be found in different singing styles, among those, lyric and Sertanejo (Brazilian country western-like singing style). Considering these two styles, the objective of the present study was to analyze the production of vibrato in the singing voice in the lyric and sertanejo genres from an acoustic and perceptual viewpoint. Twenty male singers-10 classical (operatic) singers and 10 sertanejo singers-reportedly in perfect laryngeal health, served as subjects for this study.

Rhinoscleroma: case report.

Rhinoscleroma is a chronic, granulomatous infection that most frequently affects the respiratory mucosa, especially the nasal cavity and eventually extending through the lower respiratory tract. The disease is endemic in some countries of Central America (El Salvador and Guatemala), Indonesia, India, Poland, Hungary, Russia and some African countries as well. It is a rare disease in South America.

Holoprosencephaly--report of two cases.

Holoprosencephaly (HPE) is a developmental defect resulting from incomplete cleavage of the embryonic forebrain structures during early embryogenesis. It includes a series of rare complex disorders. Chromosomal abnormalities, single gene disorders and teratogenic agents are responsible for holoprosencephaly.
