Experimental model of Opisthorchis felineus superinvasion was reproduced in 30 piglets aged 3 months. The pigs were infected by feeding them 100 g of sausage fish with the mean invasion intensity of 0.8-1 metacercaria per g of muscle tissue. A repeated infestation with a similar dose was carried out in a month. The invasion developed in 14 of the 30 animals. Histologic examinations of the liver, carried out in 2.5 months after the first infestation, have revealed diffuse persistent hepatitis in 9 animals and aggressive hepatitis in 4. Proliferative changes in the epithelium of the intrahepatic gall ducts with polyposis and diffuse focal infiltration of the wall mucosa with plasma and lymphoid cells, fibroblasts and eosinophils were found, characteristic of human opisthorchiasis. Pigs may be used as a model for experimental opisthorchiasis in research.

The number of reports about blood transfusion-related HIV and hepatitis virus infections is increasing, presently. Thus, it should seriously be considered to inform the patient of any anticipated blood loss necessitating a transfusion of blood products. This is especially necessary for surgical procedures with only a low risk for high blood loss, such as endonasal surgery as a common otorhinolaryngological procedure. However, reports about the incidence of blood transfusion during this kind of surgery are very rare. The medical histories of 6,296 patients who underwent sinus surgery between 1982-1993 in the Department of Otorhinolaryngology at the University of Kiel were analyzed. Twenty-nine of these patients received a transfusion. Risk factors for required blood, the necessity of pre-operative information and the recommendation policy for pre-operative donation of autologous blood are discussed. The intra-operative blood losses of 120 patients who did not require a transfusion and who underwent sinus surgery in 1986 and 1989, were analyzed. The transfusion rate was 0.46% on average during the 12-year period. The incidence of blood transfusion and the amount of intra-operative blood loss decreased after combination of endonasal surgery with controlled intra-operative hypotension (0.07%; p < 0.01). Risk factors for the necessity of a transfusion in these cases were extensive polyposis and purulent exacerbation of the disease. There are risks for a blood transfusion in endonasal surgery. Every transfusion carries a certain risk for the infection with HIV or hepatitis, therefore every patient should be informed about the possibility of a blood transfusion prior to the operation. Endonasal microscopic sinus surgery performed by well-trained surgeons, combined with controlled intra-operative hypotension lowered the risk for a transfusion significantly (p < 0.01).

The genomic alterations in preneoplastic lesions are summarized in this review. 3p and 9p in the lung, 9p in the bladder, 8p in the prostata, 19q and 1p in oligodendroglioma, and 22q in meningioma were reported to be deleted. Somatic mutation of p53 was found in preneoplastic lesions of the esophagus, stomach, colon, thyroid, and astrocytoma. Adenoma-carcinoma sequence (Apc, ras, p53 gene alterations) in colon, LKB1 gene in Peutz-Jeghers syndrome, Smad4 in juvenile polyposis, hMSH2, hMLH1, PMS1, PMS2 genes in HNPCC, VHL gene in kidney, WT1 in Wilms tumor, RB gene in retinoblastoma, and ret gene in MEN were reportedly altered in preneoplastic lesions involved in hereditary tumors. Cervical dysplasia and papilloma of the head and neck infected by human papilloma virus and liver infected by B-type hepatitis virus are also precancerous. Genomic instability, APC gene alteration, point mutation of K-ras in preneoplastic lesions of stomach and K-ras and p16 alterations in metaplasia of pancreas were also found. Advances in research on genomic alterations in preneoplastic lesions will contribute to prevention and early detection of cancer.
