Sarcoid is the most common tumor in horses all over the world. The sarcoid is a benign, locally invasive, usually fibroblastic proliferative skin neoplasm. Even if the etiology is not completley verified, the epidemiology and clinical behavior suggest a infectious intervention, probably BPV type 1 or type 2. However, it is known that the cause is multifactorial. A genetic prepdispositon has been identified associated to genes within the Major Histocompatibility Complex (MHC), but also to breed, age and perhaps gender.

Anafylaxi som orsakats av insektsstick är ett akut tillstånd som i vissa fall kan ha en dödlig utgång om inte rätt behandling ges i tid. Störst risk att drabbas är under sommartid samt hösten. Syftet med följande studie var att visa vilken påverkan den anafylaktiska reaktionen har i patientens dagliga liv samt vilken betydelse immunterapin har för insektsallergiska personer. Litteraturstudien bygger på åtta kvantitativa och två kvalitativa studier och granskningsmetoden som använts är Goodman. Resultatet visade att det dagliga livet hos allergiska personer för¬ändras efter allvarliga eller upprepade allergiska reaktioner samt att immunterapi var en effektiv preventions¬åtgärd mot att drabbas flera gånger av liknande reaktioner efter insektsstick..

The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).

Dagens mjölkkor har kapacitet att producera stora mängder mjölk, men deras matsmältningssystem ser fortfarande likadant ut som när de producerade mjölk enbart till sin kalv. Detta innebär att de behöver foder med högt näringsvärde, eftersom de inte obegränsat kan öka foderkonsumtionen eller passagehastigheten om fodret har lågt näringsvärde. Vanligtvis är detta inget problem under stallperioden då korna ofta har fri tillgång på foder med väl anpassat näringsinnehåll. Under betesperioden däremot kan de högavkastande korna drabbas av näringsbrist eftersom de inte kan uppfylla sina behov enbart på betesgräs. Många faktorer inverkar på kornas konsumtion av bete, en del av dessa faktorer kan påverkas av lantbrukaren.

SUMMARYThis work consists of a review of the medical records of 142 horses that visited the Equine dermatology clinic, at the University Animal Hospital, UDS, at Ultuna, Uppsala, Sweden, between January 2007 and June 2010. The study answers certain main questions like clinical signs responsible for the visit, the most common diagnoses, their diagnostic procedures, treatment modalities and finally, the outcome of treatment.Among 50 diagnoses, four were predominant followed by additional 46 diagnoses, each presenting by few or, in many cases, only one horse. The most common dermatological problem diagnosed was Equine Sarcoid representing 18,3 % of the cases (26/142), which probably reflects the initiation of a Sarcoid treatment-trial in 2007, that resulted in an accumulation of sarcoid horses in the clinic .The second most common diagnosis was Atopy 12 % (17/142) followed by Allergy with skin affection 9,2 % (13/142) and Acute superficial pyodermia 4,9 % (7/142). If the horses were divided into diagnostic groups, the majority (34,5 %) belonged to HA5 group, (Immunological skin diseases), followed by group HA4, (Infectious and inflammatory conditions of the skin) (22,5 %) and HA6, (Neoplasia) (21,8 %). Traumatic skin injuries represented only 2,1 % of the cases, compared to 80 % of horses in the Agria insurance statistics for veterinary care.The most common clinical sign and reasons for veterinary consultation was pruritus (35,9 %), suspected sarcoids (17,6 %), alopecia (12,7 %), nodules (12 %), seborrea, scaling and crusts (9,2 %) and excoriations (5,6 %), respectively, followed by a scattered number of more uncommon symtoms.The diagnostic methods most frequently applied were cytology and biopsy, used in 41,5 % and 36,6 % of the cases, respectively.
