The present study reports the clinico-pathologic changes observed in spontaneous hepatic coccidiosis caused by Eimeria stiedae in rabbits at Bannerghatta Biological Park (BBP) in Karnataka state of India. The clinical signs observed in the affected rabbits included sudden death, stunted growth, anorexia, weight loss, diarrhoea and abdominal pain. Increased liver enzymes and bilirubin was noticed upon biochemical examination. At necropsy, lesions included grossly enlarged liver (hepatomegaly) with presence of discrete yellowish-white nodules ranging from 1mm to 5mm size throughout the parenchyma containing a thick creamy white fluid. Faecal sample examination demonstrated the presence of Eimeria oocyts. The impression smears from the liver and intestinal mucosa also showed Eimeria oocysts, degenerative changes, necrotic cells and mononuclear cell aggregation to form oocyst granuloma. Histological observation revealed distension of bile duct, hyperplasia of epithelium along with numerous coccidian oocysts at the centre. Granulomatous tissues were observed to have encircled the bile duct with infiltration of inflammatory cells. Microscopic examination of exudates from liver also revealed numerous oocysts of E. stiedae. Multiple areas of coagulative necrosis of hepatic cells surrounded with inflammatory cells were also found.

Thirty young domesticated rabbits (age 2-2.5 mo) of sexes showed clinical signs of anorexia, debilitation, diarrhea, icterus, rough hair coat and pendulous abdomen with hepatomegaly. Fecal samples were collected for demonstrated the presence of oocysts. Postmortem examination revealed the presence of discrete yellowish-white nodules of 1mm to 2 cm size on the surface and throughout the parenchyma containing a thick creamy white fluid. The histopathological changes showed biliary hyperplasia with different developmental stages of Eimeria stiedae in the epithelial cells, cholangitis and peribiliary fibrosis with newly formed bile ductules, severe congestion, and dilation of central veins and sinusoids with disruption hemorrhagic areas. The hepatocytes showed degenerative changes to necrosis with areas of fibrosis and mononuclear cell aggregation, obstructive jaundice and a tendency to form oocyst granuloma. In conclusion hepatic coccidiosis lead to severe pathological changes both in bile ducts and liver parenchyma especially in young animals.

This investigation describes histologic lesions in the livers of 18 Doberman Pinschers suffering from subclinical doberman hepatitis (DH). The dogs' ages ranged from 2.5 to 7 years; 15 were females and 3 were males. At the time of liver biopsy, the dogs had no clinical signs of liver disease, although serum alanine aminotransferase (ALT) values had been elevated in two samples in successive months. In the histologic examination, all biopsies revealed parenchymal and portal mononuclear inflammation. In the parenchyma, the inflammation was diffuse, with multifocal clusters of inflammatory cells. The periportal reaction was usually mild to moderate. Bridging necrosis (3/18) and bile duct proliferation (2/18) were rare. Excessive copper was detected by rubeinic acid stain in every specimen. Postmortem liver samples were obtained from nine dogs 3.5–65 months after the initial biopsy specimen; five of these dogs had been euthanatized for reasons other than DH, and liver specimens revealed piecemeal necrosis (5/5), bridging necrosis (3/5), and bile duct proliferation (2/5). Four of them had been euthanatized because of DH. Liver lesions of these dogs were typical for chronic active hepatitis, with bridging and piecemeal necrosis (4/4), portal expansion (4/4), bile duct proliferation (4/4), and fibrosis (4/4). A scoring system was used to evaluate changes numerically from biopsy to postmortem samples. Lesions in all dogs had progressed. The most important histologic changes were expansion of portal areas ( P = 0.008), increased periportal and bridging necrosis ( P = 0.008), increased fibrosis ( P = 0.016), and proliferation of the bile ducts ( P = 0.063).

Background and Objectives: Diagnostic delay is common in attenuated Mucopolysaccharidosis Type I (MPS Ia) due to the rarity of the disease and the variability of clinical presentation. Short stature and impaired growth velocity are frequent findings in MPS Ia, but they rarely raise suspicion as paediatric endocrinologists are generally poorly trained to detect earlier and milder clinical signs of this condition. Materials and Methods: Following a consensus-based methodology, a multidisciplinary panel including paediatric endocrinologists, paediatricians with expertise in metabolic disorders, radiologists, and rheumatologists shared their experience on a possible clinical approach to the diagnosis of MPS Ia in children with short stature or stunted growth. Results: The result was the formation of an algorithm that illustrates how to raise the suspicion of MPS Ia in a patient older than 5 years with short stature and suggestive clinical signs. Conclusion: The proposed algorithm may represent a useful tool to improve the awareness of paediatric endocrinologists and reduce the diagnostic delay for patients with MPS Ia.

This chapter illustrates photos of clinical signs seen in uveitis and interesting cases of lens pathologies. Anterior uveitis is the inflammation of the iris and the ciliary body. Anterior uveitis can be idiopathic, isolated, or associated with systemic diseases. The clinical findings observed in anterior uveitis include keratic precipitates, inflammatory cells and flare in anterior chamber, hypopyon, rarely hyphema, miosis, iris nodules and atrophy, synechiae, and band keratopathy in chronic cases (shown in corneal degenerations chapter). The inflammation in anterior uveitis is almost always immune. Treatment includes steroid eye drops, cycloplegic drops, sub-Tenon steroid injections when cystoid macular edema is present. Chronic macular edema can be treated with intravitreal Triamcinolone injection and Dexamethasone implants. In cases of refractory anterior uveitis or associated immune systemic diseases, immunomodulatory treatment or biologic agents are prescribed.

Although there have been many previous studies of IgG4-related SC focusing on the differential diagnosis from cholangiocarcinoma, only a few patients with cholangiocarcinoma against a background of IgG4-related SC have been reported. We herein present a case of intraductal papillary neoplasm of the bile duct (IPNB) associated with invasive carcinoma complicating IgG4-related sclerosing cholangitis. A 71-year-old female with icterus was admitted to a local hospital, where stricture of the extrahepatic bile duct were detected, and subsequently referred to our hospital for possible surgery. Abdominal multidetector-row computed tomography demonstrated marked wall thickening along the entire extrahepatic bile duct. The left lateral superior bile duct (B2) and left lateral inferior duct (B3) were individually obstructed, and percutaneous transhepatic biliary drainage catheters were placed in B2 and B3 separately. The patient was diagnosed to have diffusely spread cholangiocarcinoma and underwent right hepatic trisectionectomy with caudate lobectomy and pancreatoduodenectomy. A histological examination revealed intraductal papillary tumors composed of fibrovascular stalks covered by neoplastic epithelium. Carcinomatous invasion of the papillary tumors was observed in the fibromuscular layer, and there was abundant infiltration of inflammatory cells with fibrosis outside of the cancerous tissue. The inflammatory cells were primarily composed of plasma cells, a majority of which were positive for IgG4 (>30 cells/high-power field); the postoperative serum IgG4 level was 890 mg/dL. Therefore, a diagnosis of coexisting IPNB associated with invasive carcinoma and IgG4-related sclerosing cholangitis was made. To the best of our knowledge, this is the first report of IPNB complicating IgG4-related sclerosing cholangitis.

ABSTRACT: Horse leukoencephalomalacia (ELEM) is a disease caused by the ingestion of mycotoxins (fumonisins) produced by fungi of the genus Fusarium that infect corn and/or its byproducts. This disease has been described by ingestion of mature corn with humidity above 15% at temperatures below 20°C. The aim of this paper was to report an outbreak of leukoencephalomalacia in horses fed with immature corn. Two horses out of three showed neurological signs approximately seven days after eating immature corn in its reproductive phase (R2, milky grains). Corn was harvested and administered directly to the animals, with no storage. Deaths occurred approximately 24 hours after the onset of clinical signs. Grossly, there were multifocal dark red to brown areas in the white matter of the telencephalon and hyppocampus and thalamus. Histologically, there was edema and hemorrhage in several areas of the telencephalon white matter, which corresponded to dark red to brown areas observed in the macroscopy. There was also foci of malacia with presence of reactive astrocytes with abundant eosinophilic cytoplasm and inflammatory cells. Diffuse capillary wall degeneration and endothelial cell swelling were also observed. Two ppm of fumonisin were detected by immunoaffinity column method (VICAM) in the immature corn sample. The water activity in this cereal, when the grain is still milky, is 0.98 and can predispose it to growth of mycotoxin-producing fungi. In the present case, fumonisin was found in milky grains in the beginning of the reproductive phase (R2), which suggested that even immature corn may be infected by Fusarium spp. and should not be administered to horses.

An attempt has been made to investigate the toxicity of cancer immunotherapy based on the dendritic cells pulsed with lysate of allogenic melanoma cell, DM401. Dendritic cells pulsed with lysate of clone M3 were subcutaneously administered once a week eight times to C57BL/6 mice at 0, 2.5, 5, and 10 × 107 cells/kg. No changes attributable to the administration were observed in clinical signs and food and water consumption. The administration induced slight increases in body weights, white blood cells, total protein, total cholesterol, triglyceride, phospholipids, and absolute spleen weights, but a slight decrease in albumin/globulin ratio. Microscopic examinations revealed the infiltration of inflammatory cells in the lung, mainly in the pulmonary arteriole, in which the tunica media thickened, and in the pulmonary alveoli and alveolar space. Thickened tunica media of pulmonary arteriole was observed in both males and females at all selected doses. In addition, the subcutis at the test substance-application site showed inflammation and fibrosis. In conclusion, lung is a target organ of DM401, and most of the changes including the findings in lung are considered as the immunomodulatory functions of dendritic cells.
