Röntgenläkarna väljer ofta att byta undersökningsteknik för att fastställa misstänkt patologi som inte går att diagnostisera med en metod. Vid röntgenundersökningar av sinus (bihålor) så kan läkaren välja mellan konventionell röntgen eller en datortomografiundersökning. Skälet är att diagnoser som tumör, benpåverkan eller ansiktstrauma inte avbildas lika bra med den konventionella metoden. Syftet med den här studien är att jämföra datotomografi och konventionell röntgen vid sinusundersökningar, vilka för och nackdelar som de olika metoderna har, hur bildinformationen och diagnostiken skiljer sig, vilka risker som finns med joniserad strålning samt vilka biologiska effekter strålningen har på människan. Intervju har gjorts med odontologi läkare som berättat om för och nackdelar med de olika metoderna, och litteratur och artiklar har gett kunskap för att komma fram till resultatet.

Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. Obstruction of the small intestine is best diagnosed by using radiography, contrast-study if needed, and ultrasound. To avoid further examinations, diagnosis from plain radiographs is preferable. One of the signs of illness one can detect from these examinations is a dilation of the small intestine proximal of the obstruction, caused by gas or fluid; ileus.

Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations. The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses. The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.

There is desire to evaluate the tracheal diameter in the Swedish population of English Bulldog, a breed with breathing disorders, and if possible use it as a criteria for breeding in the hope of improving the life situation for these dogs. The Swedish Kennel Club has together with the Swedish Club for English Bulldog and veterinarians presented a five year radiological study that has the purpose to give an average look on how the tracheal situation is in the population. The trachea will be evaluated through two different methods, both measuring two distances in the thorax. The first one compares the tracheal diameter to the height of the cranial opening of the thorax, and the second one to the width of the third rib. With the measured distances one will calculate a quotient and compares it to the reference values.This study is designed to get a preliminary evaluation, based on the 65 dogs that were available on the time for the study, with measurements done by two persons on three different occasions each.

The aim of this study was to see if an increased amount of gas could be seen in the small bowel of cats subjected to trauma and if measuring the amount of gas could be of any use in the clinical evaluation of the patient. When the peristaltic waves in the small bowel decreases due to neurological damage or chock the microorganisms of the gut grow in number and possibly produce more gas and toxins. When the cat is stressed it can swallow more air then usual, and the air that is in solution with the chyme in the lumen of the gut separates from the ingesta. When the bowel isn?t moving it becomes easier for bacteria and toxins to penetrate the wall of the gut, and then get access to the bloodstream.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

Ultrasound is a well established diagnostic method in small animal veterinary practice but there appears to be limited use of ultrasound for evaluating the musculoskeletal system. The aim of this study was to investigate what publications exist concerning musculoskeletal ultrasound of dogs and to compare the use of musculoskeletal ultrasound at the University Animal Hospital (UDS) in Uppsala, to other animal hospitals in the world. The literature review is divided into three parts, the front leg, the hind leg and miscellaneous. The literature review focuses on the musculoskeletal abnormalities that can be seen with ultrasound. The front and hind leg sections are mainly focused on the joints.

The purpose of the study is, through some aspects, to make it visible and compare the education in mathematics in classes 1-3 in Sweden and Turkey. I have also studied the mathematic lessons, textbook and teaching aids, examinations and the use of calculator, on the basis of steering documents in curriculum and syllabi. The method used in this study contains of qualitative interviews and have an unstructured character but also observations noted continuously. The result is a comparison between my own experiences and the observations connected to relevant theories and the questions..

The purpose of this review was to examine in what situations patients with myocardial infarction could feel anxiety. We also wanted to examine what a nurse could do to relieve the anxiety. The results are based on eight scientific articles and one literature review. The results shows that the patient could feel anxiety before examinations and transfers. The patient's anxiety increased if relatives had anxiety and if there were a lack of information from the nurse.

Swedish schools have during the last few years started to providing pupils in high school with tablet-computers. By doing interviews I examine how pupils in high school use tablet-computers in different ways and how that affect their studies. From a sociocultural perspective and with the concept of artefacts I analyze how suitable tablet-computers are for studies on this level of education. My results show that the tablet-computers are used as the pupils primary study tool. They are available to all pupils and can be used in most parts of their studies and this creates new opportonities in how to interact with collective knowledge and with other people.

Syftet med studien är att belysa studenters copingprocesser, d.v.s. appraisal och copingstrategier, inför examinationsformerna salstentamen och hemtentamen. En intervjustudie genomfördes med åtta kvinnliga studenter inom samma program på en högskola i Sverige. Data analyserades med induktiv tematisk analys. Resultatet visade att examinationer oavsett form skapar stress, även om studenterna inte upplever en hemtentamen som lika hotfull eller utmanande som en salstentamen.

This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.

Abortion during late gestation is often caused by placental dysfunction such as placentitis. To prevent this from happening the placenta can be monitored pre partum so treatment can be started at an early stage. Methods for monitoring the placenta include hormonal monitoring, presence of clinical signs of placental dysfunction and ultrasonographic evaluation of the fetus and the placenta. Transrectal ultrasonography provides a very good image of the caudal portion of the allantochorion where an ascending placentitis normally establishes. An increased combined thickness of the uterus and the placenta, CTUP, has been associated with placental failure. This study included ten Swedish standardbred trotter mares in late gestation. They were monitored by transrectal ultrasonography of the placenta two times with approximately a month in between. CTUP was measured on each examination.

When children are hospitalized they will face a new and unknown environment. Many children experience this situation as stressful and with fear. It is important that the nurse is aware of this fact in order to facilitate the hospitalization for the child. The purpose of this study is to investigate the fear that children feel when they are hospitalized, and to investigate the meaning of being well prepared for clinical examinations and procedures. The method used was a literature review.
