Xanthogranulomatosis is an inflammatory lesion characterized by lipid-containing macrophages, extracellular lipid, hemorrhage, and necrosis. We describe disseminated intracoelomic xanthogranulomatosis in 5 eclectus parrots ( Eclectus roratus) and 2 budgerigars ( Melopsittacus undulatus). Postmortem, clinicopathologic, and historical case material was reviewed. Ages ranged from 3 to 24 years; there were 5 males and 2 females. Table food was included in the diet of 3/5 cases, and animal products were included in 2/3 cases. Common clinicopathologic abnormalities included leukocytosis (4/5 cases) and elevated concentrations of bile acids (3/4 cases) and cholesterol within 6 months prior to death (2/4 cases). At postmortem examination, all 7 birds had grossly visible, irregular, soft, tan to yellow, amorphous plaques distributed on the surfaces of the viscera and body wall. Histologic evaluation and oil red O stain revealed xanthogranulomatous inflammation with phagocytized and extracellular lipid, necrosis, cholesterol clefts, fibrosis, and mineralization. Infectious agents were not identified with special stains in all cases. Concurrent hepatobiliary disease was present in 6/7 cases, and 6/7 had lipid accumulation within the parenchyma of various visceral organs. Five cases had atherosclerosis of great vessels. We describe a unique form of disseminated coelomic xanthogranulomatosis in 2 psittacine species. This condition should be recognized as a differential diagnosis in cases of disseminated coelomic mass formation and coelomic distension in psittacine birds, particularly in eclectus parrots and budgerigars.

The earliest distinctive lesions in human atherosclerosis are fatty streaks (FS), characterized initially by lipid-laden foam cell formation. Fibrous plaques (FP), the clinically significant lesions, differ from FS in several respects. In addition to foam cells, the FP also exhibit fibromuscular proliferation and a necrotic core region rich in extracellular lipid. The possible transition of FS into mature FP has long been debated, however. A subset of FS described by Katz etal., was intermediate in lipid composition between ordinary FS and FP. We investigated this hypothesis by electron microscopic cytochemistry by employing a tissue processing technique previously described by our laboratory. Osmium-tannic acid-paraphenylenediamine (OTAP) tissue preparation enabled ultrastructural analysis of lipid deposits to discern features characteristic of mature fibrous plaques.

Aim: Nutritional vitamin B12 deficiency in infants may occur because the maternal diet contains inadequate animal products. Clinical presentations of the infants who had nutritional vitamin B12 deficiency were analyzed in this study. Subjects and Methods: Patients with nutritional vitamin B12 deficiency were enrolled in the study between 2003 and 2010. The diagnosis was based on a nutritional history of mothers and infants, clinical findings, hematological evaluation, and low level of serum vitamin B12. Results: Thirty children aged 1 - 21 months constituted the study group. Poverty was the main cause of inadequate consumption of animal products of the mothers. All infants had predominantly breastfed. The most common symptoms were developmental delay, paleness, apathy, lethargy, anorexia, and failure to thrive. Hematological findings were megaloblastic anemia (83.3 %), thrombocytopenia (30 %), and severe anemia (13.3 %). All of the mothers had low serum B12 levels; eight of them had megaloblastic anemia. Conclusion: The unusual clinical manifestations of vitamin B12 deficiency may also be seen apart from neurological and hematological findings. Nutritional vitamin B12 deficiency due to maternal deficiency might be a serious health problem in infants. Therefore, screening and supplementation of pregnant and lactating women to prevent infantile vitamin B12 deficiency should be considered.

In recent years, the number of pasture species and cultivars commercially available to farmers in New Zealand has increased significantly. Reasons for this include increased commercial activity in the development and supply of proprietary cultivars, and more specialisation in New Zealand's pastoral agriculture. In particular, pasture cultivars are increasingly marketed as proprietary products with associated technical support. This year there are 109 certified cultivars available, belonging to 23 grass, legume and herb species. As a result, farmers are now able to develop improved pasture feed supply, but they are somewhat confused about pasture species and cultivars, and this frustrates their aims to produce high quality animal products from productive pastures. Accordingly, the herbage seeds industry needs to work from a clear reference list, to avoid any confusion when supplying farmers and overseas clients with their seed requirements. Our list of pasture species, types and cultivars available within New Zealand aims to be that reference. Keywords: birdsfoot trefoil, brome grass, caucasian clover, chicory, clover, cocksfoot, cultivars, herbs, lotus, lucerne, pasture, phalaris, plantain, prairie grass, red clover, ryegrass, seeds, species, strawberry clover, sub clover, tall fescue, timothy, types, white clover, Yorkshire fog

An epicardial mesothelial cyst, which can be defined as a mesothelial cyst attached to the epicardium surrounding the heart and the great vessels inside the pericardial sac, is a rare condition. We herein report a case of epicardial cyst, which was attached to the ascending aorta. The patient was a 76-year-old male who underwent coronary artery bypass surgery, and the cyst was found incidentally. It was approximately 5 cm in diameter, and histological examination confirmed mesothelial cell origin. The ascending aorta has not previously been reported as the origin of an epicardial mesothelial cyst. This case gives new insight into the embryology of these cysts
