Auditory steady state response in hearing assessment in infants with cytomegalovirus

OBJETIVO:Relatar o caso de um lactente com citomegalovírus congênito e disacusia neurossensorial progressiva, analisado por três métodos de avaliação auditiva.DESCRIÇÃO DO CASO:Na primeira avaliação auditiva, aos quatro meses de idade, o lactente apresentou ausência de Emissões Otoacústicas (EOA) e Potencial Evocado Auditivo de Tronco Encefálico (PEATE) dentro dos padrões de normalidade para a faixa etária, com limiar eletrofisiológico em 30dBnHL, bilateralmente. Com seis meses, apresentou ausência de PEATE bilateral em 100dBnHL. A avaliação comportamental da audição mostrou-se prejudicada devido ao atraso no desenvolvimento neuropsicomotor. Aos oito meses, foi submetido ao exame de Resposta Auditiva de Estado Estável (RAEE) e os limiares encontrados foram 50, 70, ausente em 110 e em 100dB, respectivamente para 500, 1.000, 2.000 e 4.000Hz, à direita, e 70, 90, 90 e ausente em 100dB, respectivamente para 500, 1.000, 2.000 e 4.000Hz, à esquerda.COMENTÁRIOS:Na primeira avaliação, o lactente apresentou alteração auditiva no exame de EOA e PEATE normal, que passou a ser alterado aos seis meses de idade. A intensidade da perda auditiva só pôde ser identificada pelo exame de RAEE, permitindo estabelecer a melhor conduta na adaptação de aparelho de amplificação sonora individual. Ressalta-se a importância do acompanhamento audiológico para crianças com CMV congênito.

Anatomical changes and audiological profile in branchio-oto-renal syndrome: a literature review

Introduction  Branchio-oto-renal (BOR) syndrome is an autosomal-dominant genetic condition with high penetrance and variable expressivity, with an estimated prevalence of 1 in 40,000. Approximately 40% of the patients with the syndrome have mutations in the gene EYA1, located at chromosomal region 8q13.3, and 5% have mutations in the gene SIX5 in chromosome region 19q13. The phenotype of this syndrome is characterized by preauricular fistulas; structural malformations of the external, middle, and inner ears; branchial fistulas; renal disorders; cleft palate; and variable type and degree of hearing loss. Aim  Hearing loss is part of BOR syndrome phenotype. The aim of this study was to present a literature review on the anatomical aspects and audiological profile of BOR syndrome. Data Synthesis  Thirty-four studies were selected for analysis. Some aspects when specifying the phenotype of BOR syndrome are controversial, especially those issues related to the audiological profile in which there was variability on auditory standard, hearing loss progression, and type and degree of the hearing loss. Mixed loss was the most common type of hearing loss among the studies; however, there was no consensus among studies regarding the degree of the hearing loss.

Achados timpanométricos em um grupo de escolares

PURPOSE: to characterize and compare the tympanometric findings in a group of preschoolers. METHOD: 112 preschoolers were evaluated, both genders, aged from four years old to five years and eleven months old who attended a Municipal School of Early Childhood Education in the suburbs of Marilia city- SP. Tympanometry was used as triage procedure. It was considered that the child PASSED in the triage when it presented an A type tympanometric curve, bilaterally, being reevaluated in case of failure. RESULTS: it was observed a high failure index (63.4%) in the studied population. The older female preschoolers presented a higher index of A type tympanograms, in both ears. There was a higher incidence of failure in male preschoolers aged from four years to four years and eleven months. CONCLUSION: in this sample, there was a high index of tympanometric alteration. There was a tendency among younger male students to present a higher index of tympanometric alteration when compared to older female preschoolers, this difference was not statistically significant.

Long latency auditory evoked potential in Asperger Syndrome: two case studies

Introduction: Auditory Late Responses (ALR) assess central auditory processing by neuro electric activity of the auditory pathway and analyse the activities involved in cortical abilities of discrimination, attention and integration of the brain. Individuals withAsperger Syndrome experience changes in these skills, so it is important to research these potential this population. The objective of this paper was to describe the auditory late responses of two patients with Asperger Syndrome. Methods: The study included two male patients with Asperger Syndrome, of 7 and 12 years of age, treated in a study centre. The patients did not present any auditory complaint detected by an amnesis. The external auditory canal was inspected and audiological and auditory late responses assessed. After evaluation the components P2, N2 and P3 were analysed. Results: In both patients, the latency of the components P2, N2 and P3 were elongated in both ears. Regarding the amplitude of the P2 component, reduced values were found for the left ear of patient 1 and the right ear of patient 2. The N2 amplitude was reduced for both ears of patient 1 and only the right ear of patient 2. The two patients showed a decrease in the amplitude of the P3 only in the right ear. Conclusion:This study concludes that there were changes in the ALR results in both patients with Asperger Syndrome, suggesting alteration of the auditory function at the cortex level.

Efeito da época e sistema de semeadura da Brachiaria brizantha em consórcio com o milho, sobre os componentes de produção e propriedades físicas do solo

The objective of this study was to evaluate the development of Brachiaria brizantha- MG-4; sown in two seasons and two seeding systems in space between two rows, and to evaluate the effect of intercropping on maize yield, as well as evaluating the physical properties of the soil after the consortium. The experiment was conducted in the agricultural year 2010, the Municipality of Quatro Pontes/PR. The experimental design was randomized blocks as a factorial 2x2, and an additional treatment that was corn cultivation single, with four replications. The treatments consisted two intercropping systems: corn intercropped with Brachiaria brizantha in the row, and corn intercropped with Brachiaria brizantha in space between two rows, and two times of sowing Brachiaria brizantha: simultaneously corn, and twenty-five days after sowing corn. The seed was planted mechanically in no-tillage system, with spacing between the lines of 0,70 m. The ears were harvested by hand and in the laboratory were evaluated: yield components and productivity. Brachiaria brizantha- MG-4 was sown and harvested manually. We evaluated the production of fresh and dry mass and yield components. For soil analyzes the soil was sampled at 0-0.10 and 0,10-0,20 m. Were determined the total porosity, macroporosity and microporosity. The results demonstrated that the production components of Brachiaria brizantha were lower when it was sown twenty-five days after sowing corn, and between sowing systems when Brachiaria brizantha was sown in line. There was no reduction in grain yield of maize intercropped with Brachiaria system independent and sowing date. The consortium of pasture with corn increased the total porosity, and reduced soil bulk density.

Doses, fontes e épocas de aplicação de nitrogênio em arroz de terras altas cultivado em sistema de semeadura direta

The crop demand by nitrogen varies from one crop to other as well as the amount and application time, and this nutrient can be lost by leaching, volatilization and erosion. The objective of this study was to evaluate doses, sources and times of nitrogen application in rice of high lands cropped in no till system. The work was conducted in Selviria, State of Mato Grosso do Sul, Brazil, in a soil originally under Cerrado vegetation. A randomized blocks design, with the treatments disposed in a factorial scheme 5x3x2 was used. The treatments were constituted by five nitrogen doses (0, 50, 100, 150 and 200 kg ha(-1)), three nitrogen sources (urea; ammonium sulfonitrate plus nitrification inhitor and ammonium sulfate) and two application times (at sowing or at flower bud differentiation), with four repetitions. The sources of nitrogen, as well as the application times had similar effects for most of evaluations. The N doses influenced linearly or with quadratic adjustment the plant height, N leaf content and grains yield, in the two growing seasons. The chlorophyll content and the number of ears m(-2) were affected only, in the first year. The highest yield in the growing season of 2007/08 was obtained with the dose of 149 kg ha(-1) of N. In 2008/09 growing season the increase of N doses provided increment in the grains rice yield, until the maximum dose evaluated (200 kg ha(-1) of N).

Avaliação audiológica em trabalhadores expostos a ruído e praguicida

Noise-induced hearing loss has been studied for many years and today many experts also investigate the synergic action of chemical products, since they can be potentially ototoxic. AIM: to investigate the audiological findings in workers exposed to occupational noise and pesticide and to compare it to data from noise-exposed workers. STUDY DESIGN: Clinical retrospective. MATERIAL AND METHOD: individuals that had been exposed to pesticide and noise (group I), and individuals that had been exposed to noise only (group II). RESULTS: The classification of the audiometric findings showed in that group I: 35% had normal hearing thresholds, 53.75% had degree 1 hearing loss and 11.25% had degree 2 hearing loss; and group II had 57.5% of normal hearing, 40% had degree 1 hearing loss and only 2.5% had degree 2 hearing loss. The analysis of the audiometric findings also showed a significant worsening after comparing groups I and II thresholds, in the frequency of 3 kHz on the left ear and 4 kHz on both ears. CONCLUSION: The analysis showed that group I had worse audiometric thresholds compared to group II.

Frontonasal dysplasia: clinical evaluation on audiological and brainstem electrophysiological profiles

Frontonasal dysplasia (FND) is a rare malformative complex affecting the frontal portion of the face, the eyes and the nose; it may occur singly or associated with other clinical signs. No systematic studies describing hearing in this condition were found. AIM: To evaluate hearing sensitivity and sound stimulus conduction from cochlea to brainstem in patients with clinical signs of FND. METHODS: 21 patients with isolated or syndromic FND were submitted to a clinical (otological/vestibular antecedents and otoscopy) and instrumental (pure tone and speech audiometry, tympanometry and brainstem auditory evoked response) hearing evaluation. DESIGN: A clinical, cross-sectional observational prospective study. RESULTS: Hearing thresholds were normal in 15 (70%) patients, abnormal in 5 (25%), mostly with conductive hearing loss; one patient did not cooperate with testing. The tympanometric curve was type A in 30 (72%) ears, type C in 5 (12%), type As in 4 (9%) and type B in 3 (7%). The auditory brainstem response (ABR) showed no abnormalities. CONCLUSION: Patients with FND showed no abnormalities in the auditory system from cochlea to brainstem in this study. Mild conductive hearing loss found in some is probably related to cleft palate. Further evaluation of hearing pathways at higher levels is recommended.

Manejo pré-abate de bovinos

The pre-slaughter moment begins with the animal´s loading on the farm and ends up in its drain. It is a period in which the animal is under physical stress caused by hunger, thirst, fatigue, injuries, and extremes of temperature and psychological stress, due to restraint, handling, innovation and fear. Stress and inappropriate handling bring bad consequences for the final product´s quality, requiring better handling conditions, facilities and equipment. Examples of consequences of mishandling: meat with abnormal color, DFD meat (dark, firm and dry), reduced product´s shelf life, bruises and broken bones in carcasses. The operators should be trained and oriented on the basic principles of biology, behavior and management of cattle. At every step of the pre-slaughter moment, the animals should be handled calmly and quietly to avoid excitement and stress. Operators should avoid shouting, whistling or any noise since cattle have very sensitive ears and can become stressed. If the animals refuse to move, the cause of the problem should be determined

Relações públicas e o Brand Management: storytelling 2.0 na construção de relacionamentos

According to the Informational Society of the twentieth century, man develops society of the spectacle, where life becomes virtual and the individual ceases to be a spectator becoming the protagonist of wikiciberepopéia and organizations seeking to gain the attention and time of its consumers through new communication strategies. If the great epics of mankind brought mythical heroes, divine, with powers (mostly above the mortals), in the era of new technologies, the common man is in the hands the opportunity to become the hero of his own ciberepopéia. Increasingly resistant to traditional advertising, the new model of media consumer, the prosumer, the storytelling is transforming into one of the main communication tools of contemporary organizations. Offer your audience a creative and relevant content across several media platforms is a major brand positioning strategies currently used, in addition to providing the transmission of values and organizational principles in a subjective manner. Storytelling where objects are extensions of the human body (eg, the cell can be treated as an extension of the ears) is a strong indication of a technocratic society, because we can consider the new technologies as extensions of the human brain (as new store technologies, create meanings, share information through a specific language) and the individual who is on the edge of new technology ends up being excluded from certain social events. This new world tends to put an end to separation between seemingly contrary ideas, such as reality/fiction, natural/cultural and the man who emerges from this medium is not the creator, but rather, transforming what already exists. The current human evolution takes place from about half the human mind and tell stories that go beyond the media saturation that really emocionem and who have a real meaning for those who listen, to be interconnected with the socio-environmental reality of this new consumer, is a major chall...

Pênfigo Foliáceo em cães

Pemphigus complex in animals is considered rare, but not so when compared with the occurrence of other autoimmune diseases. Pemphigus Foliaceus in dogs is the most common varieties of pemphigus and is characterized clinically by intraepidermal pustules, starting on the face and ears, pads, groin, and may become multifocal or generalized in six months. As the pustules are very fragile, the lesions usually found are secondary, which may range from dry to collarettes epidermal crusting, and nasal depigmentation. The diagnosis is difficult because presents sintomatology similar to other diseases and laboratory diagnosis more precise through the histopathological examination of pustules integrate (biopsy), which are rarely found. The treatment, although of the individual treatment regimen, is based on treating opportunistic diseases and immunosuppressing the animal in order to decrease the production of autoantibodies. The drugs of choice depend on the clinical presentation, however is usually oral prednisone and azathioprine in the dog and combined immunosuppressive therapy. Should make use daily until the disease is inactive and gradually decrease the dose until have the minimum effective dose, preferably on alternate days for the remission of the disease. Prognosis of pemphigus varies according to disease stage and treatment established. Pemphigus foliaceus is less serious nonetheless might be fatal without treatment
