Abstract
Nutritional secondary hyperparathyroidism (NSH) is uncommon in horses. Aim of this report is evaluate an alternative therapeutic approach and provide more information on the diagnostic procedures, through detailed microscopic findings of the bone lesions pony with NSH. Administration of tiludronate along with a balanced diet can be used in a treatment protocol for ponies with NSH. This case report suggests that tiludronate can be used to ameliorate the clinical signs of NSH.

Abstract
Soft tissue mineralization was diagnosed in 19 captive 2-toed sloths ( Choloepus didactylus and Choloepus hoffmanni) ranging from 2 months to 41 years of age. Gross mineralization was evident at necropsy in 6 of 19 sloths and was prominent in the aorta and arteries. Histologically, 11 sloths had arterial mineralization, including mural osseous and chondroid metaplasia and smooth muscle hyperplasia consistent with arteriosclerosis. Visceral mineralization most commonly involved the gastric mucosa (17 sloths), kidneys (17 sloths), and lungs (8 sloths). Eleven sloths ranging in age from 5 to 41 years old had moderate to severe renal disease, which may be an important underlying cause of soft tissue mineralization in adult sloths. However, 5 sloths (juveniles and adults) had severe soft tissue mineralization with histologically normal kidneys or only mild interstitial inflammation or fibrosis, suggesting other causes of calcium and phosphorus imbalance. Degenerative cardiac disease was a common finding in 10 sloths with vascular mineralization and varied from mild to severe with fibrosis and acute noninflammatory myocardial necrosis. Although the prevalence of cardiac disease in adult sloths has not been documented, disease may be exacerbated by hypertension from degenerative arteriosclerosis as noted in this study group. Although renal disease likely contributed substantially to mineralization of tissues in most sloths in this study, nutritional causes of soft tissue mineralization—such as imbalances in dietary vitamin D or calcium and phosphorus—may be an important contributing factor.

Abstract
Relata-se a ocorrência de osteodistrofia fibrosa em 38 equinos criados em pastagens de Panicum maximum cultivar Aruana, da raça Mangalarga Marchador, provenientes de uma propriedade localizada no estado do Paraná. No exame clínico geral, observou-se aumento bilateral e simétrico dos ossos da face e, também, aumento de volume na porção distal do rádio. A análise radiológica das áreas afetadas demonstrou redução da densidade óssea, e, na bioquímica sanguínea, 24 (63%) animais apresentaram níveis de fósforo elevados. O exame bromatológico revelou níveis elevados de oxalato na pastagem de Aruana. Conclui-se que a ingestão de Aruana, forragem com altos níveis de oxalato, foi responsável pelo aparecimento de lesões de osteodistrofia fibrosa em equinos.

Abstract
A 6-year-old, gelded, Paint horse displayed clinical signs of muscle wasting and limb stiffness for a 6-month period. The horse's clinical signs abated with corticosteroid therapy, but returned upon cessation of treatment. Upon necropsy, severe lesions of aortic thickening and aortic valve rigidity were observed. Histologically, the tunica media of the aorta, coronary arteries, and pulmonary arteries were expanded by foci of elastin fiber calcification and extracellular matrix with lacunae formation. The vascular lesions are comparative to what has been described as medial arterial calcification, seen in humans suffering from chronic renal failure or diabetes mellitus. No exposure to vitamin D-containing plants or feedstuff could be documented at the time of onset or during the period of clinical signs. The current case describes dramatic lesions of arterial medial calcification of the aorta, coronary, and pulmonary arteries of undetermined cause.

Abstract
Cases of equine abortion and perinatal foal losses were investigated in Hungary during a three-year period (1998-2000). Samples from aborted equine fetuses and newborn foals (total n = 96) were examined using bacteriological, virological, pathological, immunohistochemical (IHC), molecular biological and serological methods. The cause of abortion and perinatal foal loss was identified in 67/96 cases (70%); viral infection was found in 22 (23%), viral and bacterial coinfection in 1 (1%), bacterial infection in 23 (24%), protozoan infection in 1 (1%) and fungal infection in 2 cases (2%). Morphological lesions suggestive of infection were recorded in 2 (2%) and non-infectious causes in 16 cases (17%).
