Records of P III fractures from 235 horses, 71 of them were standardbreds, treated at 3 major Swedish equine hospitals (Strömsholm, SLU and Mälaren hästklinik) between 1994 and 2004 were evaluated for information such as the patients age, sex, breed, type of fracture, affected leg, time and place of the injury, treatment and, if possible, result of treatment. For the standardbreds, result of treatment was also followed up through written correspondence with owners and by screening AB Trav och Galopp racing-results. Moreover, results of horses with type II and III-fractures treated with rest and therapeutic shooing only were compared to horses in which lag screw fixation were added to achieve interfragmental compression. Compared to the rest of the Swedish horse population, P III fractures were slightly more common among standardbred horses. The mean age of the affected standardbred was 5,8 years, compared to 7,9 years in the rest of the horse-population. Most horses injured themselves in the paddock.

Hospital records of 32 non-racehorses referred to Skara Animal Hospital and Halland Animal Hospital, Sweden, between January 1995 and September 2001 for intraarticular fractures of the third phalanx, were reviewed, and follow-up information on final outcome was collected to determine whether any injury or treatment factors could be associated with the outcome. Mean age of the horses was 8.3 years (range, 1-20 years), and follow-up time ranged from 1 to 7 years after injury. In 11 (34%) of the horses, injury involved the front limbs. Twenty-two (69%) horses returned to their original level of use. There was no statistically significant correlation between outcome and elapsed time from injury to treatment, treatment variables, or bony union in the present study.

Laminitis is a debilitating disease causing much suffering to horses and ponies all over the world. It is manifested in the hooves as a mechanical failure of the suspensory apparatus between the hoof capsule and the distal phalanx. Due to the weight of the horse the disease may result in a dislocation of third phalanx. Six healthy standardbred trotters were used in this study on whether standardbreds tolerate forced recumbency as well as Shetland ponies. Recumbency was induced pharmacologically but maintained only by lowering the ceiling height of the box to a height of approximately 125 ? 140 % of the horse´s thoracic height.

Ossification of the collateral cartilages of the distal phalanx has been studied primarily in cold blooded horses. The clinical relevance of this condition is unknown. Despite this fact, since 1939, all Swedish Ardenner stallions have had to be classified as being free from this ossification to be approved for breeding. Initially, palpation was used as a diagnostic method, but since 1982 radiology has been the only method used. The aim of this study was to assess the outcome of 68 years of breeding program. Dorsopalmar radiographs were taken of the front feet of 58 Ardenners (30 mares, 8 geldings and 20 stallions) and the ossification of the collateral cartilages was evaluated and graded according to three different scales; - Ruohoniemi (grade 0-5), - Swedish University of Agricultural Science (grade 0-3), - and a new scale (grade 0-3), developed for this study.

There is an old saying, that after Epaminondas nothing was ever the same again. In this thesis I will focus on three questions: "Epaminondas the man." Who was he? "Epaminondas the general." How did he change the technique of warfare that made it possible to beat the Spartans? "Epaminondas, founder of cities and wall-builder." How did he build the walls around the cities he initiated, that made them resist enemy attacks for many years to come?While seeking the answers to yhese questions I will make a contextual analysis to get the historical background to all the phenomina involved..

Polydaktyli är en medfödd missbildning där en individ får en eller flera falanger mer än vad som är normalt hos arten. Defekten uppkommer under den embryonala utvecklingen och är sporadiskt förekommande hos häst. Hos människa tillhör den däremot en av de vanligaste hand- och fot- relaterade missbildningarna. Idag är kunskapen begränsad rörande den genetiska bakgrunden till polydaktyli hos häst. Forskningen om de genetiska faktorer som orsakar polydaktyli hos andra djurslag som t.ex.

60 million years ago the horse was the size of a small dog, and walked on four toes. Today it can weigh up to 500-1000 kg and has evolved to walking on only one phalanx. The anatomy of the horses? legs and hooves allow them to run at high speeds, and at the same time enables them to bear the extremely high concussions applied to the foot at high speeds or jumps. Every horse owner has his or her own opinion on how to manage their horses? hooves, and whether the horse should be shod or unshod. The knowledge, commitment and attention of the owner determine the quality of the hoof care, but also the time between the arising of symptoms of abnormalities of the hoof until care is sought with a farrier or veterinarian. New laws will be applied at the beginning of 2015 which bring on changes in authorization for farriers.

Syftet med detta arbete är att ge en översikt om vad som publicerats avseende patogenes, symptom och diagnosticering av PPID samt översiktligt korrelera PPID till patogenes och behandling vid fång. Hypofysen delas in i neurohypofysen och adenohypofysen, som i sin tur är uppdelad i pars distalis, pars intermedia och pars tuberalis. Hypotalamus reglerar en del av hypofysens hormonproduktion, genom frisättning av corticotropin releasing homone (CRH) och dopamin som transporteras via hypofysstjälk och blodkärl. I Hypofysen initieras respektive hämmas syntesen av hormon som ACTH. ACTH stimulerar i sin tur frisättning av kortisol från endokrina celler i binjurebarken. Kortisol fungerar sedan som en negativ feedback signal som inhiberar både sekretionen av CRH och ACTH. Pituitary Pars Intermedia Dysfunction (PPID, ofta inkorrekt kallat Cushing?s Syndrome) är rapporterat hos hästar över 12 år, med ökad incidens hos hästar över 20 år.
