Hörselnedsättning hos för tidigt födda barn ? En litteraturstudie
A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.
In-situ audiometri ? Vägen mot rätt förstärkning?
This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.
Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie
Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.
Grad av nöjdhet och ökad livskvalitet hos uni- respektive bilaterala hörapparatanvändare
Andelen äldre i Sverige ökar. Hos normalhörande äldre människor sker det en förändring i taluppfattningen som är en del av det naturliga åldrandet. Syftet med denna studie är att belysa det biologiska åldrandets påverkan på den åldrande individens taluppfattningsförmåga. En systematisk litteraturstudie har använts som metod. Resultatet från övervägande delen av använda artiklar i denna studie visar att normalhörande äldre har sämre taluppfattning än normalhörande yngre. Den försämrade taluppfattningen är enligt artiklarna ett resultat av förändringar i det centrala hörselsystemet. Artiklarna pekar på att dessa förändringar beror på förändrad lateralisering, förlångsammad kodning av talsignalen, minskad nervaktivitet eller förtvinade nerver i hörselkortex..
Om hörselskadade i BHS-utbildningen: diskursen om hur blivande bibliotekarier förbereds att möta hörselskadades behov av tillgänglighet på biblioteken
The purpose of this thesis is to determine how well a student is prepared as a future librarian at BHS in Borås, when it comes to serving individuals with hearing disabilities at the libraries. The theory and combined methods is that of discourse theory, interviews and Webb searches. The source material for this thesis comprises course material from 2002 and 2003, with the main focus on the spring term 2003 and on what is called the users perspective användarperspektivet. The study is divided into two parts: firstly, to determine the students expected knowledge and his/her future professional identity through this knowledge. The user groups that were mentioned to the students during the education were also linked to the students knowledge.
Biblioteks- och informationsvetenskap som kunskapsområde En bibliometrisk studie.
The objective of the study is to map the cognitive structure of Library and Information Science, using a quantitative, bibliometric method. This empirical study shows how co-citation analysis combined with word-frequency analysis can be used to describe the subject content of the field. The research questions to be answered are: -Which clusters of authors can be identified? -How can these clusters be described in respect of their subject content, if the descriptors associated with the authors in the clusters are counted? The results show that the cognitive structure of Library and Information Science can be described by 13 clusters of authors, where each cluster is representing a specific aspect of the subject- domain. For the description of the subject content of the clusters, descriptors DE of the LISA database have been used..

Medborgarskap i daglig verksamhet : En jämförande analys av identitet och deltagande
The aim is first to identify concept of citizenship and the dimensions of the same, in the political science theory, which can be crucial, to that a citizenship may be found available for people who have a cognitive delay. Thereafter examine the prevalence and significance of these, in policy documents from two different organizational forms, through an analysis, in the form of a discussion, on the basis of political science theories in the field. The study's aim in a reflective way, highlighting key requirements for an accessible citizenship for the target audience, and thereby clarify the priorities in daily activities that can support an emancipatory citizenship process for people who have a cognitive delay..
Kan grad av degenerativ hjärnsjukdom prediceras med hjälp av mått på kognitiv försämring?
Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.
Hörselnedsättning bland diabetiker med typ 1-diabetes respektive typ 2-diabetes ? en jämförande metaanalys
Background: Diabetes mellitus is one of today's major public health problems, affecting up to 347 million people worldwide. Several studies have shown a correlation between hearing loss and diabetes mellitus. However, it is still unclear whether this correlation differs between type 1-diabetes and type 2-diabetes.Purpose: The purpose of this study is to investigate whether there is any difference in prevalence of hearing loss in type 1-diabetics versus type 2-diabetics.Method: A meta-analysis was performed based on ten studies that were identified through the database PubMed and through manual searching of references. Odds ratios for the risk of developing hearing loss were calculated in each study. Pooled odds ratios were calculated using a random effects model.Results: Pooled odds ratios indicates that both type 1-diabetics and type 2-diabetics are more likely to develope hearing loss compared to non-diabetic controls.
Kultur för flera marknadsföring av teater för personer med dövhet eller hörselskada
Today many people with disabilities are excluded from cultural activities. The reason for this is that activities and the environment are not adapted to people with disabilities. The aim of this study is to describe the process to make cultural activities accessible and to describe the importance of good communication between cultural suppliers and their customers. Other questions raised are accessibility to cultural activities for people with hearing disabilities, the activities in the marketing process, the interaction between theatre companies and its audience and if the interaction has contributed to the theatre's future development. Qualitative interviews with staff responsible for integration at seven theatres have been performed.
Insatsens akustik och dess påverkan på hörapparatens förstärkning
The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.
Pragmatisk förmåga hos barn med hörselnedsättning : En samtalsanalytisk studie om begäran om förtydligande
Different abilities are of importance to pragmatics, there among hearing. Hearing impairment can affect language development and also pragmatic ability. The aim of the present paper was to study the pragmatic ability in terms of request for clarification in children with Hearing Impairment (HI) in conversation with children with no known hearing impairment, henceforth normally hearing (NH). The present study also describes requests for clarification sequentially in detail, and also highlights points where there may be observable differences between children with and without hearing impairment. Eight conversational pairs consisting of one child with HI and one NH child were studied.
Grupprehabilitering för äldre i audiologisk verksamhet
The purpose of this study was to investigate the results obtained from scientific articles concerning research into group rehabilitation for people over 65 years with hearing problems. The interest arose then group rehabilitation was unusual in the audiologists work, even though previous research showed these positive effects. With a group rehabilitation, the participants can easier accept theire hearing loss and hearing aid, compaired with an individual rehabilitation. The method used was a literature study. PubMed and PsycINFO databases were used in the search for literature.
Vårdnadshavares attityd, beteende och upplevda kunskap om ljudexponering och dess risker
Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.
