Benign tumors and tumor-like lesions that involve temporo mandibular joint are very rare. Those more frequent are osteochondroma, chondroma, osteoma, pigmented villonodular synovitis and synovial chondromatosis. The Authors report six cases of patients affected by these pathologies in which imaging, such as TC, MRI and/or ortopantomography have been useful to have a diagnosis.
The Authors report an interesting case of liposarcoma of the leg and review the international Literature. Moreover, a particular analysis of different aspects such as anatomy, clinic, diagnosis and treatment has been carried out.
The aim of this work is the investigation of the level of expression of the vascular endothelial growth factor (VEGF) and metalloproteases (such as Cox-2) in the colon rectal cancer. The final goal is the correlation with liver metastases. Molecular biology approaches will be adopted: in particular: RT-PCR, quantitative real time PCR with fluorescent probes, immunolocalizations and Western blotting This is a proposal of research. The work is under development and results and conclusions cannot be at the moment anticipated. However, in recent publication we found human polyomavirus DNA sequences in colorectal tumors.
A modified esophagocardioplasty with gastric patch in the treatment of advanced achalasia is presented. The technique was employed in 4 patients from 1977 through 1993 and satisfactory results were obtained in follow up studies up to 16 years. This procedure provides better passage through the esophagogastric junction with preservation of the antireflux mechanism.
The trend of the National mortality rate for gastric cancer in the general population and in the old people between 1955 and 1990 was studied. A decreased incidence of mortality in the general population whereas an increased mortality rate in elderly was found. Between 1990 and 1994, 17 patients over 70 years of age were operated on for gastric cancer. The influence of the ASA classification on postoperative complications was then evaluated registering a significant statistical difference between patients included in ASA III group and or > and major complications and mortality (P = 0.044). The surgical strategy in the management of elderly patients with gastric cancer is also discussed.
