- ItemAcesso aberto (Open Access)Perda auditiva neurossensorial súbita idiopática: evolução na presença de hipertensão arterial sistêmica, diabetes melito e dislipidemias(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2010-06-01) Nagaoka, Jayson [UNIFESP]; Anjos, Marcelo Ferreira dos [UNIFESP]; Takata, Thales Takeo [UNIFESP]; Chaim, Renan Moukbel [UNIFESP]; Barros, Flavia [UNIFESP]; Penido, Norma de Oliveira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Retrospective study aiming at evaluating the interference of associate diseases in the evolution and prognosis of idiopathic sudden sensorineural hearing loss. MATERIALS AND METHODS: Case-Control Study. Thirty-five patients with idiopathic sudden sensorineural hearing loss were divided in two groups, one of them with associate diseases (hypertension, diabetes mellitus and dyslipidemias), and another one without co-occurrence of such diseases. The groups were evaluated regarding: age, gender, associate diseases, presence of tinnitus, dizziness and ear fullness sensation, presence of cerebral microangiopathy observed in magnetic resonance imaging, ophthalmoscopic findings, treatment onset, improvements in audiometric findings and at speech discrimination tests. Statistical analysis of data was performed. RESULTS: The associate disease group showed higher ages, cerebral microangiopathy observed in magnetic resonance imaging and later improvement in speech discrimination tests, being this difference statistically significant. CONCLUSION: Idiopathic sudden sensorineural hearing loss co-occurring with hypertension, diabetes mellitus or dyslipidemias, in older patients, is associated with a higher prevalence of cerebral microangiopathy, revealed by magnetic resonance imaging, and associated with a slower hearing recovering, showed by later improvements in speech discrimination tests.
- ItemSomente MetadadadosPerfil da leptina e adiponectina na perda auditiva neurossensorial súbita idiopática(Universidade Federal de São Paulo (UNIFESP), 2016-12-15) Maranhao, Andre Souza de Albuquerque [UNIFESP]; Penido, Norma de Oliveira Penido [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: To investigate the profile of leptin and adiponectin in onset of idiopathic sudden sensorineural hearing loss as also study their prognostic influence on hearing recovery of patients. Methods: A prospective cohort study, controlled, was conducted. Patients with idiopathic sudden sensorineural hearing loss, seen from August 2013 to March 2015, followed by outpatient clinic of Department of Otorhinolaryngology and Head and Neck Surgery, Paulista School of Medicine/ Federal University of São Paulo. We evaluated the initial and final audiometric parameters, the latter being obtained after at least 30 days after the end of treatment and/or hearing stabilization (minimum follow-up of 30 days). Two blood samples were collected, one prior to treatment and another at least 1 month after the end of treatment, in order to determine the serum levels of the adipokines: leptin and adiponectin. Patients were divided into 2 groups: significant hearing recovery (RSA) and non-significant hearing recovery (RNSA). Results: Twentyfour patients with ISSHL met the inclusion criteria of the study group. 17 (71%) were females and 7 (29%) were male. The mean age was 53.6 years, with a median of 56.5 years, standard deviation of 13.7, minimum age 20 years and maximum age of 76 years. The control group consisted of 22 individuals, 15 (68%) females and 7 (32%) were male. The mean age was 52.5 years, with a median of 54 years, standard deviation of 13.5, minimum age of 28 years and maximum age of 73 years. Leptin serum concentration in the control group was 33.2 ng/ml, in the RSA group 48.5ng/ml (p=0.20) and in the RNSA group 33.7 ng/ml (p=0.61). The serum concentration of adiponectin in the control group was 7.1 ?g/ml, in the RSA group it was 5.2 ?g/ml (p=0.30) and in the RNSA group 4.6 ?g/ml (p=0.10). The leptin initial plasma concentration in the RSA group was 48.5 ng/ml and the final concentration was 32.3ng/ml (p<0.002) and in the RNSA group the initial concentration was 32.7 ng/ml and the final concentration was 26.7ng/ml (p=0.07). There was no statistically significant difference in plasma concentrations of adiponectin within each group. Blood levels of adipokines before and after treatment between the RSA and RNSA groups had no statistically significant difference. Conclusion: The serum concentrations of leptin and adiponectin in the onset of sudden idiopathic sensorineural hearing loss do not differ from individuals without this condition. Serum leptin concentration significantly reduced in patients with idiopathic sudden sensorineural hearing loss wich evolved with good auditory prognosis.
- ItemAcesso aberto (Open Access)Reconhecimento de fala no nível de máximo conforto em pacientes adultos com perda auditiva neurossensorial(Sociedade Brasileira de Fonoaudiologia, 2009-01-01) Zaboni, Zuleica Costa [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To obtain the Percentage Index of Speech Recognition (PISR) at maximum comfortable level (MCL) in adults with mild to moderately severe (up to 60 dB) sensorineural hearing loss. METHODS: The subjects evaluated were grouped according to the degree of hearing loss (Groups I, II and III). The groups were further divided into subgroups (IA,IB, IIA, IIB, IIIA, IIIB) as it follows. In the subgroup A of each group, the PISR was determined at 40 dB SL, beginning with the right ear. The patient was then requested to inform how comfortable the sound was at this level of stimuli presentation, according to a scale with four possibilities: low, comfortable, high and excessively high. After that, the maximum comfortable level (MCL) was obtained, and the PISR was carried out using that intensity level. In the subgroup B of each group, the same procedure was carried out, only reversely, performing initially the PISR at MCL, and then at 40 dB SL. In this subgroup the test began with the left ear. RESULTS: After evaluating the subjects of the three groups, the mean MCL was calculated. It varied from 25 to 32.95 dB SL. The subjects had better results in the PISR when stimuli were presented at MCL. CONCLUSION: PISR evaluation at MCL, for individuals with mild to moderately severe sensorineural hearing loss, provides better Speech Recognition results.
- ItemAcesso aberto (Open Access)Transient otoacustic emissions with tone pip in individuals with sensorineural hearing loss(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2011-10-01) Takeda, Thays Bueno; Gil, Daniela [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Otoacoustic Emissions are generated by the cochlea in response to sound stimuli. They can be generated by clicks or specific frequency stimuli, such as tone pips. This is a quick and objective test with several applications. OBJECTIVE: To investigate the influence of the type of stimulus achieving otoacoustic emissions in individuals with mild and moderate sensorineural hearing loss of sloping configuration. MATERIAL AND METHOD: Thirty-two male and female patients aged from 17 to 63 years, with symmetric sensorineural hearing loss with a sloping configuration were evaluated. All subjects underwent transient otoacoustic emissions testing elicited by clicks and 2.000Hz and 4.000Hz tone pips. RESULTS: The degree of hearing loss and gender influenced otoacoustic emissions; it was significant for click stimulus and tone pips at 2.000Hz. Emissions were absent more often in females with both procedures. CONCLUSIONS: Otoacoustic emissions evoked with clicks coincided with the emissions of tone pips at 2.000Hz. Tone pips at 4.000Hz were more sensitive than clicks for detecting impairment in individuals with high frequencies hearing loss. Gender and the degree of hearing loss ere factors that affected OAE registration.
