The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Working as a veterinary nurse includes advising animal owners, helping them to make discisions through well-based facts and experience. Preemptive spaying of the healthy bitch brings many advantages and disadvantages. It leads to cessation of gonadal hormone production, and how the exact extent the surgery affects the dog is not yet fully understood. The sex hormones mainly control the reproductive system, but receptors of these hormones are found in many tissues of the body, and have complex relationships with other hormone systems. Spaying decreases the metabolism although the bitch gets an increased appetite, which enhance the risk of obesity, unless the owner restricts food intake.

Bakgrund: Överviktsoperationer ökar i snabb takt runt om i världen i samband med en eskalerande fetmaepidemi. En överviktsoperation innebär stora förändringar i livet och ställer krav på att sjukvårdspersonal är kunniga om dessa förändringar ur patientens perspektiv.Syfte: Syftet med litteraturstudien var att belysa patienters upplevelser före och efter överviktskirurgi.Metod: 13 vetenskapliga artiklar granskades och analyserades. Sammanställningen resulterade i ett tema och fem presenterade underkategorier.Resultat: Överviktskirurgi blev en sista chans till ett bättre liv för patienterna. De hade förväntningar på ett förändrat liv, som i många fall till stor besvikelse inte blev bättre. Patienterna upplevde att den mentala hälsan blev åsidosatt vid överviktskirurgi, varav de önskade att vårdpersonalen la mer fokus på just detta.Slutsats: Då överviktskirurgi är en livsomvälvande process är det viktigt att sjuksköterskan har förståelse för patientens hela upplevelse, även den känslomässiga..

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

Bakgrund: Patienter som ska genomgå elektiva operationer kan uppleva preoperativ oro och ångest. Preoperativ oro kan grundas i bristande information, tanken på att mista kontrollen samt vistelse i okänd miljö. Det vilar ett stort ansvar på sjuksköterskan då hon ska möjliggöra optimal delaktighet i vård och behandling för patienten samt uppmärksamma patienter som inte själva uttrycker ett omvårdnadsbehov. Syfte: Att sammanställa kunskap om vilka omvårdnadsåtgärder som kan minska patienters preoperativa oro vid elektiva operationer. Metod: Litteraturstudie, baserad på två kvalitativa och åtta kvantitativa artiklar.

The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.

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.

Background: Children in our present society spend more time sedentary, and food has become more accessible. It is important to pay attention to obese children, because of the risk for serious diseases in the future. Obesity can also cause mental suffering for the child. Aim: The aim of this study was to describe the nurse?s care of obese children.

Bakgrund: Deposition av fibrillär amyloid beta 1-42 (A?) i hjärnan är ett välkänt kännetecken för den neurodegenerativa sjukdomen Alzheimer?s (AD). Dessa ansamlingar påverkar pericyter, en celltyp involverad i blodkärlsfunktion och upprätthållande av blodhjärnbarriären (BBB). Pericyter uttrycker både receptorn low density lipoprotein receptor related protein 1 (LRP-1) till vilken A?1-42 binder, och proteoglykanet NG2.

Degaardt, M & Rubensson, M. Postoperativt förlopp efter dagkirurgisk ljumskbråcksoperation. Uppföljningssamtal som grund för kvalitetsutveckling. Examensarbete i omvårdnad 15 högskolepoäng. Malmö högskola: Hälsa och samhälle, Utbildningsområde omvårdnad, 2010. Syftet med denna studie var att göra en bedömning av den postoperativa förloppet i hemmet hos dagkirurgiska ljumskbråcksopererade patienter. Data insamlade med hjälp av högstrukturerade telefonintervjuer.

Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.

Shivering är ett fenomen som uppstår hos patienterna postoperativt. Det innebär att patienten har okontrollerbara muskelskälvningar som gör att patienten darrar, skälver eller huttrar i mer än 15 sekunder. Shivering påverkar kroppen negativt, men är också obehagligt och ett onödigt lidande för patienten. I takt med den tekniska utvecklingen utarbetas nya operationstekniker och idag utförs flera operationer med laparoskopisk teknik. Pilotstudiens syfte var att undersöka före-komsten av postoperativ shivering hos patienter som opererats med laparoskopisk teknik.
