A model for spontaneous tumour formation in the rat pancreas is described that requires neither cocarcinogens nor dietary manipulation. Short term hypercholecystokininaemia, when induced by raw soya flour feeding, induces benign and malignant tumours of the rat pancreas. Pancreaticobiliary diversion (PBD) results in hypercholecystokininaemia and in the(More)
We present a case of plasmacytosis of the mucous membrane of the upper aerodigestive tract. This is a rare benign condition characterized by plasma cell infiltration of the mucosa, with only nine cases described previously (Ferreiro et al., 1994). The lesions, which have a cobblestone appearance, cause throat discomfort, dysphonia and mild dyspnoea. All the(More)
The histopathological appearance of proliferative squamous lesions removed from the skin of iatrogenically immunosuppressed patients differs subtly from that of classical malignant and premalignant epidermal lesions. The majority of cases show 'Bowenoid' changes with a marked degree of cellular atypia including characteristic multinucleate cells.
In an effort to reduce morbidity associated with transfusion of blood products, Amicar is used as a prophylactic inhibitor of hyperfibrinolysis associated with diffuse perioperative bleeding in patients undergoing open heart surgery. Previous studies indicate a significant reduction of intraoperative and postoperative bleeding in patients receiving Amicar(More)
Twenty-six benign oncocytic lesions of the salivary glands, excluding Warthin's tumours, have been reviewed and criteria for their classification as oncocytoma, multifocal nodular oncocytic hyperplasia, diffuse oncocytosis, pleomorphic adenoma with oncocytic change or oncocytic monomorphic adenoma have been proposed. The histological and clinical features(More)
Fine needle aspiration cytology (FNAC) was performed on 91 patients with lesions of salivary glands and cervical lymph nodes. The results were compared with histopathology in 58 patients who subsequently underwent surgery. Of a total of 105 aspirates, a definitive cytodiagnosis was possible in 88 (83.8%). An overall sensitivity of 77.7% and specificity of(More)
The incidence of pancreatic cancer is increased in patients who have undergone gastric surgery. An animal model is described in which pancreatic hyperplasia and adenoma formation developed within 56 weeks. The effects of a simple gastrojejunostomy were compared with those after a split gastrojejunostomy, in which the jejunum was transected and the two limbs(More)
Haemosuccus pancreaticus is a rare cause of gastrointestinal haemorrhage, and when it presents in otherwise healthy people, can prove difficult to diagnose. The cardinal features are episodic epigastric pain associated with a raised serum amylase and the passage of melaena. Failure to make the connection between recurrent gastrointestinal bleeding and(More)
