Treatment of tympanic membrane perforation using bacterial cellulose: a randomized controlled trial.

INTRODUCTION Promising treatments for tympanic membrane perforation closure have been studied. Therapies derived from tissue engineering probably eliminate the need for conventional surgery. Bacterial cellulose is presented as an alternative that is safe, biocompatible, and has low toxicity. OBJECTIVES To investigate the effect on healing of direct application of a bacterial cellulose graft on the tympanic membrane compared to the conventional approach with autologous fascia. METHODS Randomized controlled trial. Forty patients with tympanic membrane perforations secondary to chronic otitis media were included, and were randomly assigned to an experimental group (20), treated with a bacterial cellulose graft (BC) and control group (20), treated with autologous temporal fascia (fascia). We evaluated the surgical time, hospital stay, time of epithelialization and the rate of tympanic perforation closure. Hospital costs were compared. The statistical significance level accepted was established at p<0.05. RESULTS The closure of perforations was similar in both groups. The average operation time in the fascia group was 76.50 min versus 14.06 min bacterial cellulose in the group (p=0.0001). The hospital cost by the Brazilian public health system was R

Otomicroscopic and histologic findings of induced myringosclerosis in rats: a critical study of an experimental model

Oral motor dysfunction begins after 3 months of age and is severe.

Achados otomicroscópicos e histológicos da miringoesclerose induzida em ratos: estudo crítico de um modelo experimental

UNLABELLED Temporal ordering and auditory attention are important skills in information processing, being evaluated by a behavioral test, as the frequency pattern test (FPT) in temporal ordering (TO) and electrophysiological testing, as the P300 in auditory attention. OBJECTIVE To analyze the applicability of FPT and P300 as testing for auditory processing. METHOD We performed an integrative literature review, with papers that met the inclusion criteria, using the MedLine, LILACS and SciELO databases, with the keywords: hearing attention, P300 evoked potential, P300 and electrophysiology, temporal ordering, processing and FPT. We found 13 papers concerning the use of the TPF and 16 regarding the use of P300. RESULTS The TPF was the most used test in the evaluation of TO, presented in a diotic way in individuals with language disorders, musicians, blind people, rural workers and different age groups. The P300 is used in the frequency of 1000 Hz in the frequent stimulus and 2000 Hz for the rare stimulus, applicable in individuals of both genders, different age groups, and in patients with Down syndrome, liver cirrhosis, AIDS and Sleep Apnea Syndrome. CONCLUSION The FPT and P300 are efficient instruments used to assess the intended skills.

A bulimia nervosa como fator de risco para distúrbios da voz: artigo de revisão

UNLABELLED Myringosclerosis is characterized by hyaline changes of the lamina propria of the tympanic membrane. Experimental studies have used otomicroscopy or histology to evaluate myringosclerosis in animals, but they do not correlate precisely these two methods. AIM The present study evaluates the accuracy of otomicroscopy in the diagnosis of myringosclerosis in rats. STUDY DESIGN Experimental. MATERIAL AND METHOD Myringosclerosis was induced by transtympanic inoculation of Streptococcus pneumoniae in 25 Wistar rats, which were examined weekly through otomicroscopy and sacrificed after eight weeks for histologic study of their tympanic membranes. RESULTS From the comparison of the otomicroscopic data in relation to the histologic findings, we could observe sensibility of 80% and specificity of 75% for the otomicroscopy. CONCLUSION Considering the results in this study, otomicroscopy did not represent a good method to evaluate myringosclerosis in this experimental model.

The importance of electrically evoked stapedial reflex in cochlear implant

A miringoesclerose e caracterizada por hialinizacao da lâmina propria da membrana timpânica. Trabalhos experimentais tem utilizado a otomicroscopia ou a histologia para estudar a miringoesclerose em animais, porem sem correlacionar precisamente estes dois metodos de avaliacao. OBJETIVO: Este estudo procura avaliar a acuracia da otomicroscopia no diagnostico de miringoesclerose em modelo experimental com ratos. FORMA DE ESTUDO: experimental. MATERIAL E METODO: Foi induzida miringoesclerose por inoculacao transtimpânica de Streptococcus pneumoniae em 25 ratos Wistar, que foram examinados quinzenalmente por otomicroscopia e sacrificados apos oito semanas, tendo suas membranas timpânicas examinadas por histologia. RESULTADOS: Da confrontacao das alteracoes otomicroscopicas com os achados histologicos, houve uma sensibilidade de 80% e especificidade de 75%. CONCLUSAO: Pelos resultados obtidos neste estudo, a otomicroscopia nao representou um bom metodo para avaliar a miringoesclerose neste modelo experimental.

Bulimia nervosa as a risk factor for voice disorders: literature review

Bulimia nervosa (BN) is a type of feeding disorder that starts in adolescence and presents a variety of symptoms, recurrent vomiting in the oral cavity that may reach down to the larynx - similarly to gastro-esophageal reflux, causing laryngeal and voice disorder alterations. AIM: These studies aimed at surveying the literature and investigate the studies that considered BN a risk factor for voice disorders. RESULTS: of the ninety three papers we found, twenty-three were used as a basis for this review, among them, only three discuss BN as an etiology factor associated with voice changes in adult women, and we did not find any paper associating this with bulimic teenagers. CONCLUSION: It is necessary to observe laryngeal and vocal signs and symptoms associated with BN, especially in teenagers whose voices are going through a period of change.

A importancia do reflexo estapedico evocado eletricamente no implante coclear

Introduction: The most important stage in fitting a cochlear implant is the identification of its dynamic range. The use of objective measures, in particular the electrically elicited stapedius reflex, may provide suitable assistence for initial fitting of cochlear implant, especially in children or adult with multiple disorders, because they provide specific values that serve as the basis of early cochlear implant programming. Objective: Verify through a review the use of the electrically elicited stapedius reflex threshold during the activation and mapping process of cochlear implant. Methods: Bibliographical search on the Pubmed and Bireme plataforms, and also on Medline, LILACS and SciELO databases, with standard searches until September 2012, using specific keywords. For the selection and evaluation of scientific studies found in the search, criterias have been established, considering the following aspects: author, year/location, grade of recommendation/level of evidence, purpose, sample, age, mean age in years, evaluative testing, results and conclusion. Results: Among 7,304 articles found, 7,080 were excluded from the title, 152 from the abstract, 17 from the article reading, 43 were repeated and 12 were selected for the study. Conclusion: The electrically elicited stapedius reflex may support when programming the cochlear implant, especially in patients with inconsistent responses.INTRODUCTION The most important stage in fitting a cochlear implant is the identification of its dynamic range.
