A report on my thesis developing an algorithm to automatically classify a mammogram image as containing an Implant or not and segmenting and masking any present breast Implant in the image..

Osseointegrated titanium Implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after Implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of Implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the Implant and there are theories that this has effects on the marginal bone loss. The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.

Children with Reading and Writing Difficulties and Their Language and Cognitive AbilitiesA Comparison with Children with a Cochlear ImplantAbstractThe aim of this study was to examine the cognitive abilities that are important for reading in children with reading disabilities, children with a cochlear Implantation and typically developed children. 64 children aged 10-12 years participated in the study. To answer the question at issue we used the following tests: Block Design from WISC III, PPVT III, TOWRE, SL 40 and a few chosen tests out of the SIPS battery. On tests of the lexical access children with reading disabilities performed at the same level as hearing children, while the children with a cochlear Implant performed significantly lower. Test of the phonological and complex working memory showed that children with reading disabilities performed significantly higher than children with a cochlear Implant, but at the same time lower than typically developed children on the test of phonological working memory.

A study was carried in conjunction with the Orthodontic department at Halmstad General Hospital in Sweden to investigate the possibility of reducing cost and manufacture time of dental Implant drill guides. The current system involves sending a digital image in STL format to the Materialise factory in Belgium where information of the position of dental Implants is translated onto a moulded mouthpiece. Drill guides are placed in the mouth piece which is then returned to the surgeon. The mouthpiece complete with drill guides is then placed in the patients mouth and used as a guide for the Implant drill holes. The cost of 10000 sek and a turnaround time of 2 weeks gave rise to the need for a faster and cheaper solution.

Dental Implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make Implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for Implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Cochlear Implant has become a common treatment for people with severe hearing loss. As the field of cochlear Implants is developing rapidly a larger group of patients will be Implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear Implant treatment and to identify surgical issues that have to be addressed during Implantation. Method: A review of retrospective case studies regarding complications has been made.

The aim of the study was to investigate the performance of postlingually deaf adults on parts of the swedish dysarthria test Dysartribedömningen, and to compare these results with a matched group consisting of normal hearing speakers without any known speech disorder. The group consisted of 17 participants ranging between 42-86 years of age. Participants were assessed focusing on articulation, prosody, intelligibility and through a self-assessment of communicative participation. There was a statistically significant difference between groups on prosody that manifested primarily as a slower speaking rate in the cochlear Implant users. No significant differences between groups as to articulation, intelligibility or communicative participation could be found.

Denna rapport presenterar det examensarbete som gjorts i samarbete med företaget ArtImplant. Syftet med arbetet är att ta fram en prototyp av ett meniskImplantat i trikåteknik. Det kräver stickning av en given form och att prototypen ska inneha vissa egenskaper.Ämnesområden som berörs under arbetets gång är textiltillverkning med inriktning mot väfttrikå samt medicinsk textil. Förutom textila ämnesområden tas även ämnen som knäledens anatomi och meniskens uppbyggnad, funktion och skador upp. Kunskaper inom dessa områden krävs för att på bästa sätt ta fram prototyper av meniskImplantat.Att sticka det triangulära tvärsnittet och den böjda formen som krävs för ett meniskImplantat har varit ett arbete som pågått under hela projektet.

Databases are an easy way of storing information kept together and accessible and can save time by finding the information easier. CochleaImplant could be seen as a form of advanced hearing aid, this product consists of two parts, an external part that recieves sound and sends signals to the internal part through electromagnetism. The internal part is the Implant itself and is surgically placed in to the cochlea. Örebro University hospital has just started working within the field of CochleaImplants and are therefore in need of a database to store patient related information.The database problem was solved using Microsoft Access 2003 combined with the built-in support for Visual Basic, which is a sort of programming language. The result of the thesis work was a fully functioning database according to the given specification and is now being used at Örebro University hospital..

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear Implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Ett program som simulerar signalbehandlingen i ett cochleaImplantat med signalbehandlingsstrategin ACE (Advanced Combined Encoder) har konstruerats. Programmets främsta syfte är att i förväg prova ut inställningar i ett cochleaImplantat och genom detta försöka förutsäga olika användares individuella inställningar. Programmet har validerats med utsignaler bearbetade av Cochlear Limited i deras egenkonstruerade Matlab-modul för forskning inom cochleaImplantat, NMT (Nucleus Matlab Toolbox). Samma insignal som använts av Cochlear Limited har processats av programmet och utsignalerna från detta jämfördes med utsignalerna från NMT. De bägge utsignalerna, producerade med samma inställningar, stämde bra överens. Komprimeringsfunktionen i programmet, som är en vital del av signalbehandlingen, visade sig stämma bra överens med NMT:s komprimeringsfunktion, sånär som på en relativ minskning av värdet vid starka insignaler. Programmet ska nu användas på CochleaImplantat-sektionen vid Uppsala Akademiska sjukhus för att pröva ut individuella inställningar till användare av cochleaImplantat.

The literature review also illustrates the effect of the treatment opptions on soft tissue with mucositis and peri-Implantitis surrounding dental Implants. The study reviews twelve scientific articles that have been processed from the aim of the study. The result shows six therapy options, Er:YAG laser, air abrasive, ultrasonic device, hand instruments, hand instruments in combination with antibiotics and hand instruments in combination with clorhexidin. The following methods are described according to how they are used and how they affect the soft tissue surrounding dental Implants.

Background: Bone anchored hearing system is a surgically Implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for Implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..

We aim to develop knowledge of how new technology, in this case social media, can contribute to how sports fans interact with their idols. Therefore our framing of a question is to present how fans experience their contact with mixed martial arts (MMA) & ultimate fighting championship (UFC) through social media platforms. To specify our study, we also have a supplement question with in which way sports fans uses social media.We have chosen to conduct a qualitative study consisting of interviews and data observations of websites, related to the organization UFC, to approach our main question. We have interviewed nine randomly selected people with one common interest - MMA/UFC. With an Implant of theories, consisting of social media, fandom and lurking, on the result of the interview and website data, we try to come closer to a conclusion for our intention with this thesis.Our conclusion is that the interviewed fans express that through the usage of social media, they feel like they have come closer to UFC.
