Surgery is the only hope to cure gastric cancer. The aim of surgery is the complete removal of the tumor (UICC RO-resection), which is known to be the only treatment modality proven effective and the most important treatment-related prognostic factor. The type of surgical treatment for gastric cancer is determined by the patient's medicosurgical status and the stage of disease. Improved survival and quality of life(QOL) are the major criteria for the therapeutic strategy. For patients with early gastric cancer, minimal invasive surgery is attempted for the improvement of QOL. Minimal invasive surgery can be performed only when there is no evidence for residual disease, especially in lymphnodes. Therefore, precise prediction and selection of node-negative patients is important for the application of minimal invasive surgery. However, long-term survival data are needed for these new techniques to become more generally accepted. For patients with advanced gastric cancer, aggressive and extended surgical approaches are recommended for the improvement of survival. Distal subtotal gastrectomy is the procedure of choice whenever tumor-free margin can be obtained, with the exception of proximal tumors that can be treated by total gastrectomy. Extended lymphadenectomy should be the choice of lymphadenectomy for experienced surgeons with a low morbidity and mortality. If a surgeon can perform combined resection of adjacent organs safely, it is recommended when a direct invasion is suspicious. Distal pancreatectomy should be avoided unless direct invasion is definite. Splenectomy for the purpose of lymph node dissection is be mandatory, and surgeons should consider preservation of the spleen when there is no definite splenic hilar lymph node enlargement or any direct invasion to the spleen. Cytoreductive surgery with intraperitoneal chemotherapy is a useful and promising procedure for the treatment of peritoneal metastasis. The therapeutic approach should be stratified according to the patient's status, tumor status,and QOL after resection. Above all, the treatment strategy should be specific and tailored to each patient for the improved survival and QOL.

It has been postulated that programmed cell death via apoptosis may be critical for remodelling of glomeruli after inflammatory injury. To understand the regulatory mechanism of apoptosis in experimental crescentic glomerulonephritis (CGN), we examined the MIB-1 score (proliferation index, PI) and apoptotic index during the progression of experimental CGN to end-stage renal failure. CGN was induced in New Zealand White rabbits by administration of guinea pig anti-GBM IgG after sensitization with guinea pig IgG and their kidneys were analyzed for the development of crescents through sequential renal biopsies. Serum creatinine levels progressively increased in a time course until day 45. The PI in glomeruli, tubular epithelial cells, and interstitium progressively increased during the progression of experimental CGN. The mean numbers of MIB-1 positive intraglomerular nuclei (PI) were significantly correlated with degrees of crescent formation and the numbers of apoptotic cells in the glomeruli, tubules, and interstitium. Significant apoptosis was present from day 1 (15.8 10.16 cells/glomerular cross section) and increased in number with the proliferative lesions as glomerular inflammation continued. Moreover, apoptosis increased during the resolution of the glomerular inflammation, and many apoptotic cells were present in the sclerotic lesions in day 17 (18.6 12.99 cells/glomerular cross section). As glomerular inflammation subsided, cellular crescents progressed to fibrous crescents with a reduction of cellularity by day 45. On day 45, the glomerular PI and the numbers of apoptotic cells were markedly decreased. The correlations found in CGN between the creatinine level and the percentage of crescents, between the percentage of crescent and PI, and between the PI and number of apoptotic cells support the hypothesis that there is a change in the glomerular and tubulo-interstitial apoptosis under pathologic conditions. These findings indicate that apoptosis plays an essential role in the resolution of intra- and extraglomerular inflammation and in the elimination of glomerular cells within the sclerotic regions for progressive CGN. The regulation of the apoptotic phenomenon and increased PI during CGN may be important in the progression of glomerular inflammation and the development of pathologic glomerular sclerosis.

This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.
