In this essay suggested pathogenesis of secondary hypertrophic osteoarthropathy (HOA) is reviewed. HOA, characterized by; periostitis, periosteal proliferation of tubular bones and arthritis can develop due to many different underlying diseases. The syndrome is most commonly seen with intra-thoracic malignancy or chronic pulmonary infections. HOA has previously mainly been described in humans and various domesticated species. More recently, through wildlife disease monitoring, cases have also been found among wild animals.

Pyometra is a common and life threatening disease of intact bitches. The disease is caused by a hormonal influence on the uterus in combination with a bacterial infection. The most common treatment is ovariohysterectomy, but several medical options are available to maintain fertility or avoid surgery and anaesthesia. Drugs that can be used for medical treatment are for example progesterone-receptor antagonists, Prostaglandins and dopamine agonist. The present study focused on treatment with the progesterone-receptor antagonistaglepristone in combination with antimicrobial therapy.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

Pyometra är namnet på en av våra vanligaste och allvarligaste hundsjukdomar. Sjukdomen drabbar främst äldre tikar och innebär en varig och inflammerad livmoder. Den exakta patogenesen diskuteras fortfarande, men alla är överens om att sjukdomens utveckling beror på ett samspel mellan en hormonellt påverkad livmoder och opportunistiska bakterier. Tikar som drabbas blir ofta mycket snabbt nedsatta och tillståndet kräver akut behandling. Den vanligaste och säkraste metoden innefattar en operation där livmodern och äggstockarna opereras bort. De senaste 30 åren har emellertid en hel del studier gjorts av möjligheten att behandla pyometra medicinskt för att kunna bevara den reproduktiva förmågan hos tiken.
