A 2-month-old foal with septic shock and severe respiratory distress was referred to the Veterinary Teaching Hospital. Due to poor prognosis, the foal was euthanized. Histopathology showed lesions suggestive of Rhodococcus equi infection associated with a diffuse interstitial infiltrate of foamy macrophages and syncytial cells presenting large acidophilic intranuclear inclusion bodies, fibrin e...

Despite the worldwide distribution and prevalence of Schizophyllum commune, an emerging basidiomycetous pathogen, human infections occur only rarely. We describe the first well-documented pulmonary infection caused by S. commune which disseminated to the brain of a 58-year-old patient undergoing empiric corticosteroid therapy. Magnetic resonance imaging scans revealed ring-enhancing masses. His...

IN SUMMARIZING THE RESULTS OF THIS WORK I FEEL JUSTIFIED IN DRAWING THE FOLLOWING CONCLUSIONS: 1. The fuchsin body represents a type of body subject to wide variations in morphology and in staining reaction. 2. Though more frequently associated with plasma cells than with any other cell type, these bodies may and do occur in a great variety of cells. 3. Further, certain sections show unmistakab...

Sex cord-stromal tumors with annular tubules (SCTAT) of the ovary are rare. They have two clinical presentation forms: the syndromic form, which is associated with Peutz-Jeghers syndrome, and the non-syndromic form, which is frequently seen in the second or third decades. We describe a 13-year-old patient who underwent left oophorectomy. Macroscopically, the mass was 16×13×8 cm in diameter, enc...

Refractile eosinophilic granular cells, when present in abundance in a glioma, may trigger a diagnosis of the relatively familiar and inherently malignant 'granular cell astrocytoma'. The following two cases remind us that refractile eosinophilic granular cells are not unique to granular cell astrocytoma but can also dominate the histology of oligodendroglioma confirmed by 1p19q loss, and the i...

Primary synovial chondromatosis is a rare, benign, proliferative disease of hyaline cartilaginous bodies within the synovium of joints. We report a rare case of primary synovial chondromatosis diffusely affecting the ulnohumeral joint causing pain and motion limitations with extrusion into the cubital tunnel and compressing the ulnar nerve but without any preoperative signs or symptoms of ulnar...

While non-alcoholic fatty liver disease (NAFLD) is highly prevalent (15% to 45%) in modern societies, only 10% to 25% of cases develop hepatic fibrosis leading to cirrhosis, end-stage liver disease or hepatocellular carcinoma. Apart from pre-existing fibrosis, the strongest predictor of fibrotic progression in NAFLD is steatohepatitis or non-alcoholic steatohepatitis (NASH). The critical featur...

Hopping provides efficient and energy saving locomotion for kangaroos, but it results in great forces in the knee joints. A previous study has suggested that a unique fibrous cartilage in the central region of the tibial cartilage could serve to decrease the peak stresses generated within kangaroo tibiofemoral joints. However, the influences of the microstructure, composition and mechanical pro...

J Bone Joint Surg [Br] 2009;91-B:997-1006. Chondral damage to the knee is common and, if left untreated, can proceed to degenerative osteoarthritis. In symptomatic patients established methods of management rely on the formation of fibrocartilage which has poor resistance to shear forces. The formation of hyaline or hyaline-like cartilage may be induced by implanting autologous, cultured chondr...

Cartilage has a poor intrinsic repair capacity, requiring surgical intervention to effect biological repair. Tissue engineering technologies or regenerative medicine strategies are currently being employed to address cartilage repair. Mesenchymal stem cells (MSCs) are considered to be an excellent cell source for this application. However, the different gene expression profiles between the MSCs...
