Förekomst av arteriell insufficiens : och samband till postoperativa sårinfektioner i de nedre extremiteternabland patienter som opererats med Coronary Artery Bypass Graft
The purpose of this study was to investigate the presence of arterial insufficiency in patients undergoing CABG surgery and whether arterial insufficiency is a risk factor for postoperative wound infections in the harvesting leg. Patients who had CABG surgery were enrolled consecutively. A total of 144 patients participated in the study. During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.
Nipahvirus : patologi hos en nyupptäckt zoonos
Nipahvirus is most likely spread from bats to other species and causes lethal encephalitis in humans and respiratory illness in pigs. Different species are affected with varying severity but it seems to have an unprecedented zoonotic capacity and the humans affected either die or receive permanent brain damage. Full recovery is possible but very uncommon. Pigs that live and are bread in the areas that these bats frequent are constantly in danger of contracting pneumonias and meningitis and they can spread the virus further on to the people who work with the pigs and process their carcasses. These workers could then infect other humans in their immediate surroundings, their families for instance.
Lungfibros hos hund : fallbeskrivningar, histopatologi samt analys av surfaktantproteiner
Idiopathic pulmonary fibrosis (IPF) is a chronic respiratory disease with an
estimated incidence of 3-6 cases per 100 000 inhabitants in Sweden. There is no
cure for the disease, which inevitably leads to death. A similar disease has been
found among terrier dogs, with an especially high prevalence in the West
Highland White Terrier (WHWT). Dogs with pulmonary fibrosis become
lethargic with exercise intolerance, and in some cases they develop cough and
respiratory distress. This thesis gives a brief review of the field of pulmonary
fibrosis and presents a method for analyzing surfactant proteins in
bronchoalveolar lavage (BAL) in the dog.
Mastcellens funktion vid försvar mot infektioner
The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.
Blodtrycksmanschett eller manuell handkompression vid bedömning av venös insufficiens i Vena saphena magna
Bakgrund: Venduplex har på senare år vuxit fram som den mest använda metoden vid diagnostik av venös insufficiens eftersom det är en ofarlig, kostnadseffektiv, non-invasiv metod med hög sensitivitet och specificitet där både den anatomiska placeringen av insufficiensen samt den funktionella förändringen av venen kan påvisas direkt vid undersökningen. Olika manövrar kan genomföras för att påfresta venklaffarna och därmed framkalla en eventuell reflux, men det är oklart om de olika manövrerna kan påverka den reflux som provoceras fram och därmed också påverkar bedömningen av insufficiensgraden.Syfte: Syftet med studien var att undersöka om det förelåg skillnad i graderingen av insufficiensen samt om den maximala refluxhastigheten påverkades beroende på vilken manöver som användes för att framkalla en reflux.Metod: 20 v. saphena magna mitt på låret med påvisad reflux deltog i studien. Två upprepade mätningar genomfördes där venklaffarna provocerades med hjälp av en blodtrycksmanschett över vaden, med en manuell kompression över låret samt med en manuell kompression över vaden.Resultat: Den maximala refluxhastigheten blev 0,33±0,20m/s när en blodtrycksmanschett över vaden användes, 0,31±0,22m/s när en manuell handkompression över vaden användes samt 0,17±0,16m/s när en manuell lårkompression genomfördes.Slutsats: Ingen signifikant skillnad på maximal refluxhastighet kunde konstateras när en automatisk uppblåsbar blodtrycksmanschett över vaden jämfördes med en manuell handkompression över vaden. En signifikant högre maximal refluxhastighet konstaterades när en manuell vadkompression jämfördes med en manuell lårkompression..
Basalmetabolism hos barn och ungdomar med cystisk fibros : En jämförande studie av uppmätta och beräknade basalmetabolismvärden
Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.
Finns det daglig variation i resistans i de nedre luftvägarna hos häst?
Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.
Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :
Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals.
A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact.
Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial.
The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.
Äldre personers upplevelser av att leva med kronisk arteriell cirkulationsinsufficiens i benen
Den främsta orsaken till arteriell cirkulationsinsufficiens i benen är ateroskleros vilken har nått epidemiska proportioner i många länder. De två vanligaste symtomen är ?fönstertittarsjukan? och kritisk ishemi där risken är stor att patienten förlorar benet om behandling inte sätts in. Få studier har gjorts för att undersöka människors upplevelse att leva med kronisk cirkulationsinsufficiens i benen. Syftet med denna studie var att beskriva äldre personers upplevelser av att leva med kronisk arteriell cirkulationsinsufficiens i benen.
Klinisk gradering av hästens luftvägsstatus : en jämförande studie av kliniska graderingsprotokoll samt deras relation till luftvägshälsa och neutrofilförekomst i BAL-vätska
Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.
African swine fever in Uganda : description of a recent outbreak and possible differential diagnoses
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.
Vilometabolism hos barn och ungdomar med Cerebral Pares : En deskriptiv korrelationsstudie
Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).
Temporär eosinofili i lungsköljprov hos häst :
This work reveals the results of BAL performed on horses included in a larger study that assessed the relationship of amount and type of inhaled particles in equine stable air on indices of respiratory inflammation in horses and people. During this study an unanticipated and marked elevation in lung eosinophils was detected in a number of the horses. The possible significance and cause of this pulmonary eosinophilia was investigated further, and is the main focus of the work presented.
Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer
Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis. Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis. ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.
Mitralisinsufficiens hos hund : patofysiologi och behandling
Myxomatös klaffdegeneration är en vanlig hjärtsjukdom hos hund och därför av stort veterinärmedicinskt intresse, både ur patofysiologisk och ur farmakologisk synvinkel.
Hos människa kan klaffen opereras och ersättas med en konstgjord klaff, men hos hund är inriktningen framförallt att med medicin förbättra överlevnaden då en mild klaffinsufficiens är fullt möjligt att leva med. Detta för att hos det enskilda djuret förhindra att sjukdomsförloppet förvärras och hjärtsvikt uppstår.
De mediciner som används profylaktiskt idag ges ofta utan att man genom kliniska försök påvisat en positiv effekt genom ökad livskvalitet och/eller överlevnad. Detta är inte optimalt då sjukdomsförloppet är långdraget och medför stora kostnader för djurägaren utan att man vet om det verkligen har önskad effekt och dessutom kan medföra oönskade biverkningar..
